Morality of Abortion Essay

Introduction In this paper, I will argue that abortion is morally acceptable in certain situations. In defending this argument I will include the reason behind my decision, and I will provide an alternate example using the same general principle. After explaining my principle I will give clarity to two arguments that may be presented by others. Finally, I will conclude by describing any changes that I have made to my general principle. II. Argument 1.) If a person is in a situation in which she can prevent an individual from living a life of pain and suffering, then it is morally acceptable for her to do so. 2. ) In cases in which a mother is in a situation in which she can prevent her unborn child from living a life of pain and suffering, by having an abortion 3. ) Therefore, in this cases it is morally acceptable for a mother to have an abortion. III. Explanation Rule one states â€Å"an argument is good for you if and only if all of the premises are reasonable for you to believe. † For this rule I will use a similar situation with the same general principle. If Allison is a situation in which her favorite dog severely breaks his leg and can not be repaired, then it is morally acceptable for her to euthanize the dog. In this example it is morally acceptable to euthanize the dog because the dog will not be able to walk again and will suffer because it will not be able to move. Therefore, if a person is in a situation in which she can prevent an individual from living a life of pain and suffering, then it is morally acceptable for her to do so. The second and third premise state that (1) In a case where a mother is in a situation in which she can prevent her unborn child from living a life of pain and suffering, by having an abortion (2) Therefore, it is morally acceptable for a mother to have an abortion. In explaining my argument I will give an example that supports the second and third premise. If a mother is in a situation in which she becomes aware that her unborn child has an extremely painful and incurable disease called Epidermolysis Bullosa, EB. This disease causes skin to blister on the slightest touch. many infants that are born with this disease are are con? ned to wearing bandages at all times and can not even with stand their own parents touching them. In this case then it is ok for that mother to have an abortion. This act is ok because if the child is born with a disease that is incurable and painful then that child will be in will suffer for their whole lifetime and in many cases live a very short life. Therefore if a mother is in a situation in which she is able to prevent her unborn child from living a life of pain and suffering then it is morally acceptable for her to have an abortion. Rule two states that the argument must have a pattern such that if the premises are true, then the conclusion must follow. 1. ) If P, then Q 2. ) P 3. ) Therefore, Q 1. ) If P (a person is in a situation in which she can prevent an individual from living a life of pain and suffering), then Q (it is morally acceptable for her to do so. ) 2. ) P (In a case where a mother is in a situation in which she can prevent her unborn child from living a life of pain and suffering, by having an abortion), 3.) Therefore, Q (in some cases it is morally acceptable for a mother to have an abortion. ) IV. Objection An objection that may arise from premise one is that if a person is in a situation in which they sacri? ce their own life to prevent pain and suffering of another individual, then it is not morally acceptable for them to do so. An example of this is if Peter is in a situation in which he can take the place of a person in solitary con? nement, which causes psychological pain and suffering, it is not morally acceptable for him to do so. It is not morally acceptable because although the individual is suffering they knowingly participated in the act that resulted in the pain and suffering. This example expresses a violation of rule two because the argument does not follow a pattern in which the conclusion follows. Another objection that may arise from premise one is if a mother is in a situation in which she can violate the right to life of another person, the fetus, and the fetus is not threatening the mothers life, then it is morally wrong for the mother to violate the fetus’ right to life. My response to this argument is that although the mother’s life is not in danger by having the fetus, after the fetus is born they will live a short and extremely difficult life. This example is a violation of rule two because the premises are not reasonable to believe. V. Conclusion When thinking about the situation previously stated in the paper, I thought about the many options that could be presented when confronted with information, such as the fetus has an incurable and highly painful disease. By weighing the pros and cons of each principle I was able to construct my principle that was stated above. While writing this paper I have changed my general principle by adding the word â€Å"suffering. † By adding this one word I believe that it changes the argument by including another aspect that can make a life unbearable. When ? rst thinking about the reasoning behind my paper I thought about all view points that I could take, but I was able to stay true to my original belief of pro-choice by creating an argument that supports one aspect of the abortion debate.

Soul Food

When you think of soul food what is the first thing to come to mind? I think of southern foods as flavorful spicy foods like gumbo or jambalaya. Soul food has been around since the slave days and is described as a type of foods that are associated with African-American culture in the southern United States. Soul food recipes were typically a reflection of the chef’s creativity, after the abolition of slavery, most African Americans lived in poverty, so recipes continued to make use of cheaper ingredients.Of course, this isn’t entirely a black/white issue. Historically, there hasn’t been much of a difference between the foods eaten by poor black Southerners and poor white Southerners. They usually used meats like chicken, liver etc. newly freed slaves used this type of cooking to their advantage because they didn’t have much money to live with. Since slaves weren’t aloud to read or write, recipes were passed down orally for several generations.There were no widely distributed soul food cookbooks until the late 1960s and early 1970s. Around the 60s and 70s black-owned soul food restaurants began to appear in New Orleans, Birmingham, and other southern cities. presently soul food restaurants from fried chicken and fish â€Å"shacks† to upscale dining establishments-are in every African-American community in the nation, especially in cities with large black populations, such as Chicago, New York, New Orleans, Los Angeles and Washington, DC .Over centuries, soul food has been cooked and seasoned with pork products, and fried dishes are usually cooked with hydrogenated vegetable oil like Crisco which is a trans fat. Unfortunately, regular consumption of these ingredients without significant exercise or activity to work the calories off often contributes to disproportionately high occurrences of obesity, hypertension, cardiac/circulatory problems and/or diabetes.It has also been a factor in African-Americans often having a sho rtened lifespan. More modern methods of cooking soul food include using more healthful alternatives for frying (liquid vegetable oil or canola oil) and cooking/stewing using smoked turkey instead of pork. This is why over time soul food has been cooked with more healthy ingredients. Now, soul food is the one of the most common foods across the country and is associated with comfort and happiness for a lot of people.

A META-ANALYSIS OF ADOLESCENT OBESITY AMONG IMMIGRANT LATINO Essay

A META-ANALYSIS OF ADOLESCENT OBESITY AMONG IMMIGRANT LATINO POPULATION IN - Essay Example Thus, it is more comfortable for them to eat in fast foods and do not spend much time on cooking at home. A problem of obesity is a complex phenomenon that should be considered on the social, economic, psychological and cultural levels. A target group chosen for the research consists of immigrant Latino population in San Antonio, Texas. It has been often claimed, that ethnic minority groups are subjected to a high risk of becoming obese in comparison with other Americans. Lower living level, other spheres of occupation, a lack of proper education, inability to have a constant access to information about healthy way of life and possibilities to live this kind of life and many other factors have prevented ethnic minorities from being healthy people. Therefore, this target group is one of the most vulnerable social groups to the destructive influence of obesity. POPULATION: Latinos have become the largest racial/ethnic minority group in the United States of America, and are expected to grow to about one-fourth of the population by the year 2050 (Delva, O'Malley & Johnston, 2007). The term Hispanic is used interchangeably with Latino and refers to descendents of at least 25 different countries, all of which are Spanish speaking (Centrella-Nigro, 2009). Definition of Hispanic or Latino origin used in the 2010 Census refers to a person of Cuban, Mexican, Puerto Rican, South or Central American, or other Spanish culture or origin regardless of race (U.S. Census Bureau, 2010). Hispanics now make up 38 percent of Texas’s 25.1 million people, up from 32 percent a decade ago. Bexar County, which includes San Antonio, grew by 23.1 percent and is home to 1.7 million. In accordance with the 2010 census San Antonio population grew by 25 percent to 1.33 million people , the Hispanic population grew by 25 percent making to 63.2 percent Hispanics in San Antonio (U.S. Census Bureau, 2010). According to the Texas Department of State Health Services, over 30% of adolescents in Texas are overweight or obese. That is 1 in 3 teenagers. Obesity is not just a physical condition –it has many psychosocial implications that need to be acknowledged. PREVALENCE: According to the Health Profiles 2005 by The San Antonio Metropolitan Health District (SAMHD) the Hispanic population is expected to far outpace other ethnicities by 2040 and beyond. The Hispanic population faces well-documented health concerns, such as obesity. Programs addressing those areas should be maintained or increased. Bexar County’s Hispanic population is also younger with fewer college graduates than any other ethnic population. Those factors are often predictors of future poverty and increased risk for associated health problems such as obesity. Unfortunately, 90% of Hispanics in Bexar County have not earned at least a 4-year college degree. Moreover, the Hispanic population is burdened with additional risk factors for childhood obesity, including parental obesity, low socioecon omic status (SES), recent immigration, acculturation to US diet and lifestyle, and limited health insurance coverage, ethnic beliefs, differences in ideal body images, lack of appreciation of weight management, questionable literacy levels, and access to medical care (Wilson, Adolph, & Butte, 2009; Centrella-Nigro, 2009; & Harrington, 2008).

The School Nurse Essay Example | Topics and Well Written Essays - 1000 words

The School Nurse - Essay Example However, in today's world the school nurse position is not given the resources necessary to accomplish this goal and the role has become so unmanageable and the task so encompassing it may be placing education and students at risk. The number of students taking Ritalin has doubled since 1990 and now exceeds 3 million students (Goldberg, 1). The over worked nurses must medicate these students to insure the proper dose to the correct student. The pervasiveness of lunchtime medication has become so involved and lines of children outside nurses' offices so prevalent, that in Boston, schools are now facing a challenging dilemma; Who should have responsibility for the medicating According to Carey Goldberg, reporter for the New York Times, "...school officials have proposed that individual nurses be given permission to delegate the distribution of their ''meds'' to handpicked, supervised staff members". Many nurses who advocate the addition of higher paid nurses as a solution rather than reducing their roles have discredited the plan as unsafe. However, school officials see it as a reasonable cost cutting measure in this New World of psychoactive drugs. Untrained personnel handing out sensitive and dangerous drugs a re certainly placing the students at an increased risk. School nurses are called upon to walk obese students, insert catheters, and administer diabetic insulin. These are disciplines that call on the highest order of medical training. Food poisoning, infectious diseases, sexually transmitted diseases, and injuries from student violence complicate these situations. The nurse is required to perform the duties of a general practitioner while having the training of a nurse and the attendant pay scale. Still, school systems balk at the possibility of adding more nurses to the staff due to cost considerations. While the National Association of School Nurses recommends that a school system have one nurse per 750 students, the national average is one nurse per 1350 students (Vail). Attending to the students medical needs should be a priority to assure that the system is promoting adequate and fair education, but staffing at a 50% level can not guarantee success of the health of the student body. Obesity is running rampant through the school corridors and nutrition and healthy food have come into the spotlight. Once again, the school nurse is called on to make recommendations and plans to provide a healthy diet and reduce the problem of overweight children. Nutrition is a special discipline and often runs counter to the school's agenda of providing vending machines and a junk food cafeteria. There is more profit in a McDonald's station than there is in a healthy dietary offering. The American Medical Association advocates a proactive approach based on food types and amounts that are to be offered through school lunches ("Expert Committee Recommendations", 8). Dedicated school nurses can not be expected to protect the health of children in the existing political and economical climate of many school boards. They are not trained as nutritionists and do nor serve the political function of being socially

Analyzing of Organs for Sale Essay Example | Topics and Well Written Essays - 750 words

Analyzing of Organs for Sale - Essay Example Paying people for offering their kidneys would increase donors and this would save lives as opposed to waiting and wishing to get people to donate their kidneys voluntarily at no cost. The author poses a great question to support her argument that, if it is legal and right to pay men for giving out or donating sperm, why then is it hard to pay people for donating kidney? This question helps readers to think critically about why it would be great to donate body organs to save the society. The author concludes her article that, legalizing organ selling would benefit the society by saving thousands of lives. Overall, the article is great in content as the author does an outstanding job at giving facts to reinforce her points and convince readers why they should believe in her argument. The article creates a platform for readers to understand various benefits that would emerge in a society if the government regulated and emulated organ selling. This would save lives and eradicate the high rate of poverty especially in third world countries. From these points, it is evident that organ selling would be profitable for health and economic purposes. Additionally, the article is well-written and documented with facts that many people suffer from kidney disorders. For instance, the article highlights that over 300, 000 Americans suffer from kidney disorder. Unfortunately, most victims die since there are no drugs that revive a damaged kidney rather than replacing another kidney. At this point, the author argues that kidney transplantation is the best option to cure the disorder since it is reli able and safer than other treatment that may negatively affect the patients’ body. These facts outlay the benefits of kidney transplantation and why many people should opt for the idea. In great thoughts, the author uses facts to support her argument. For instance, she brings into attention that there is a surplus of kidneys especially in third countries

Embryo Gene Activation Essay Example | Topics and Well Written Essays - 1000 words

Embryo Gene Activation - Essay Example Embryonic genes, which are active prior to the 4-cell stage, are small in number and they code for proteins used in controlling and stabilizing maternal mRNA and proteins. Parental proteins regulated at the post-translational glassy by adjusting the proteins phosphorylation form. Alternatively, these protein states created by the embryonic kinases can stimulate the activities of proteins and change their cell location. For embryo development, change and degradation of maternal mRNA proteins are crucial just before the embryo gene activation. This paper discusses embryo gene activation, DNA repair and the pathways involved in the processes (Lauritzen 240). During the 4-cell phase of embryo gene activation, remodeling of chromatin, which allows transcription of the embryo, and hence synthesizing the translation machinery. The genome of embryos becomes active and starts transcription of metabolic, apoptosis and cell cycle protein regulation (Khanna &Yosef 119). The proteins for maternal mRNAs continuously reduce in the early phases of the 4-cell phase. Signaling pathways for embryonic gene activation example is the hedgehog signaling. The signaling pathway that transfers information to embryonic cells helps for right development. Each part of the embryo can contain different concentrations of these signaling proteins. Not only in embryonic cell development, this kind of pathway has a bigger role in adults and malfunction can cause diseases like, basal cell carcinoma. This signaling pathway is a focus regulator in most animals’ growth (Song & Lee 48). In some other animals, lack of this pathway can lead to poor development of the brain, lungs, and the skeleton. Hedgehog signaling is crucial in regulating the maintenance and regeneration of most adult cells and tissues. Pharmaceutical companies have associated this pathway as a cause of cancer and developed drugs to cure the signaling causing diseases (Polin, William, & Steven 58). Breast cancer susceptibilit y gene 1 (BRCA1) and BRCA2 are genes which suppress tumor and the mutant phenotypes that predispose to both ovarian and breast cancers. These proteins are involved in most cellular processes and contribute DNA repair and regulation in response to the damage of DNA (Ensley 113). BRCA proteins protect the genome from damage by providing maintenance of the stability of chromosomes. The big number of cellular proteins, which interact with the BCRA, propels most functions of the BRCA proteins and their functions linked to different phosphorylation events. Reasons why these proteins cause both ovarian and breast cancer are unknown today (Knobil, Jimmy & Neill 69). These proteins are present in breast cells where they help repair the damaged DNA or destroy the cells in cases where the DNA is unrepaired body (Alpi, Pasierbek, Gartner & Loidl 16). Damaging the BRCA1 by any chance causes the damaged DNA not repaired and this may increase the chances of cancer. Most mammals have complex mechan isms to monitor damage of DNA and the required responses to maintain their integrity and repair. Some of the mechanisms for detection, repair, and cell cycle arrest to prevent damage from gametes or embryo cells (Gordon 670). The repair of the DNA in these newly formed embryos relies on the mRNA proteins from prior ovulation. These repair genes developed in the early stages of the animal development need to be enough to equip the embryo with the maternal products for the gene expression to start at the right

Final examination - Essay Example stede’s dimensions for comparative cross-cultural studies, and they have led to many useful explanations of cross-cultural differences in consumer behavior. The main reason that may have rendered Hofstede’s useful is that these dimensions are independent. Only two dimensions are interdependent, and these are collectivism and power distance. Together with national wealth, Hofstede’s dimensions can be used to explain more than half of the differences in consumer behavior. Tompenaars’ dimensions do not show results that are as consistent as the Hofstede dimensions. The word cultura is a Latin word closely related to cultus which means cult or worship. Therefore, culture may be considered as the result of human action. According to Hofstede (2001), national culture is the broadest level of culture that a person can be a member of. People are shaped by their national culture from their early childhood through beliefs, values and assumptions inherent in it. The theory of cultural dimensions is central to the study of consumer behavior across the world especially in analyzing the effect of culture on consumer behavior. The Theory of Cultural Dimensions was introduced in 1980 by Geert Hofstede. This theory was based on his study of cultural solutions to organizational problems involving 117,000 employees at IBM in 40 countries. According to Hofstede (2001), the individualism dimension describes the relations between the individual and the collectivity that exists in a given society. His dimension represents a society that has loose ties between ind ividuals. Individualistic countries stress the importance of human independence, and individual liberty and self-reliance. Individualists promote the unrestricted exercise o individual goals and desires. Mooij (2010) terms power distance as the degree to which less influential members of the public admit that power is unevenly distributed. In the world, there are both high-power and low-power distance cultures.

History of Modern Architecture Essay Example | Topics and Well Written Essays - 1000 words - 1

History of Modern Architecture - Essay Example The postmodern structures aimed seeking meaning and expression various architectural techniques, styles, forms. In order to meet with the aims, the postmodern architecture had to reject the strict rules of the modernism movement. On the other hand the modern structures were purely based on a thrifty use of material and other aspects of postmodern architectures like ornamentation, were absent (Curtis, 1987). The functionalism of modernism movement was dull and unattractive. It compelled the postmodern architects to focus on the communicating meaning; therefore, they start quoting historic traditions of architecture and merging it with modern designing creating new meaning. The revival of columns in structures is a common example, widely practiced throughout the world. This revival was to meet the aesthetical need but to fulfill a technological requirement. Similarly, Prairie home concept was based on designing structures that match humanity and the environment. Frank Lloyd Wright was the leader of this movement, and he named this philosophy organic evolution. Prairie house plan is sweeping horizontal lines and wide open floor plans. Furthermore, the concept of Prairie is characterized with central chimney, one-story projection, and numerous small windows. His ‘Falling water’ is considered as the best example of organic architecture (Curtis, 1987). Postmodernist architecture has evolved from modernism, incorporating traditional ways of architecture through modern technology and innovations. Contrary to a formalism of the International Style of modernism, the postmodernist architecture is based traditional wit, ornamental and reference. In other words the formal styles and functional way developed during modernism is replaced by styles, collide, a form is used. Hence, postmodern architecture revitalized the centuries old traditional

Catering for a variety of learners Essay Example | Topics and Well Written Essays - 500 words

Catering for a variety of learners - Essay Example With the tremendous pace of globalization it is seen that multilingual students exist all over the world and this has created a subject for research. It is believed by many that these multilingual students are at a loss if they do not excel in the primary language which is being used in schools and universities. However this belief is denied by many when it comes to excellence and perfection. This essay would further analyze the works of Cummins and Clarkson in relation to these aspects (Cummins 2006; Clarkson 2006). Multilingual and Bilingual students are able to speak two or more languages which gives them an edge over others who can speak only one language. English is primarily used for educational curriculums and hence these multilingual students are encouraged to excel in that specific language. In many schools English as a language is promoted for these multilingual students whereby their mother language is ignored. The teachers in these schools believe that English as a primary language is more important than other languages when it comes to studies. However this is denied by several researches done by Cummins and Clarkson. It is seen that Cummins in his researches is denying these beliefs and stating that it is necessary for students to learn all the languages and excel in them accordingly. According to his researches it is seen that students who have a grip on different languages are able to build up excellent rational critical techniques (Cummins 1979; Cummins 2006) These techniques he lp them to excel in education and further improve their base. Clarkson affirms this view by researching on Australian Vietnamese students and how their bilinguals help in developing their rationality of mind. Mathematics is a subject of thought and being bilingual helps these students to think even more. The research by Clarkson showed that students who had a grip on many languages showed more positivity when it came to studying mathematics in the

Bodybuilding Essay Example for Free

Bodybuilding Essay Bodybuilding BY adam5701 When a bodybuilder, fitness, figure, or physique competitor begins to prepare for a contest there are so many different variables that go into how you are supposed to train. From personal experience, exercise order has not made a huge impact for the results I was striving to achieve. As long as I do not work the same muscle group within a 48-hour period (since that is the typical recovery time for your muscles to fully repair), I have achieved amazing results. Here are a few other things I highly recommend doing, which if not done properly it almost makes it impossible to ucceed. First hire a reputable coach, I initially made the mistake of taking a shortcut and hired someone because they were cheap which made me place dead last in my first competition. Since then I paid the money and hired someone who knew the ins and outs of competing and it has done wonders for me. A coachs Job is to typically plan out your diet, workout routine, supplementation, posing routine, and best of all its great to have someone else looking at you once or twice a week to see how you change and what else you need to improve on. Yes, I could have done all this on my own but this outside eye makes a huge difference and trying to plan all this out while youre brain dead from dieting can be difficult at times. Next thing is to plan out every little detail in your workout, diet, and sleep schedule for every hour each day. Consistency is a big part of competing and if you are not consistent you will not see any of the results you desire. When attempting to gain muscle mass or density, most people automatically think they have to lift heavy in order to grow. Personally I have found it much more useful o lift at a lower weight with a rep range from 8-20 depending on the exercise. I still see amazing results because each time I do this I make sure I fatigue the muscle and push it until failure. The way I achieve this is by making my rest time between sets and exercises no more than 60 seconds for a single workout, and up to 90 seconds for a drop set (which is starting off with a high weight for a low amount of reps and increasing the reps as you drop the weight, I typically drop the weight about 3-4 times). There was also a study performed where Regardless of the number of reps erformed, the subjects burned 52% more calories when they rested Just 30 seconds between sets as compared to three minutes or more. Working at 10 reps per set burned about 7% more calories than five-rep sets did (Stoppani, Jim, Flex pg. 1). There are also other things I do in order to fatigue my muscle and cause growth, rather than Just focusing on rest time. As shown in my workout plan notes you will notice that my 1 5 to 20 repetition exercises are more towards the beginning of my workout. I have it set up this way because I do not do conventional stretching before orking out since it essentially lowers the amount of weight or reps I can perform. Instead I do these warm up sets of 15 to 20, and this isnt Just light easy rep weight, I make sure its enough to where once I get to those last two reps I feel as if my muscle will give out. This enables blood to flow into the muscles and essentially gets them warmed up and ready for the heavier tasks. Another thing I love incorporating are three workouts of 1 or 2 muscle groups you are training, which I normally choose exercises that are opposite in movement), focus on the time and length of ontraction, and lastly a rest pause (which if I do not perform all 20 reps and only get to 13, I will rest for 20 seconds and complete the remaining 7). Training with these different intensities on random workouts makes a huge difference for strength and muscle gain. The main reason I have found this effective is because I am constantly tearing down my muscle fibers with a different method each workout. Another big thing to think about when training for competitions, or even Just working out in general is to achieve the mind and body connection. My theory on this s that its impossible to workout the muscle you are targeting if you are unable to feel it. In other words an isometric contraction, because any type of muscle growth and performance depend primarily on the neuromuscular system (Yessis pg. 1). A good way to practice would be Just to attempt to flex each individual muscle, which at first is very difficult for someone who is Just starting out. Also doing this between sets for 6-10 seconds can actually promote muscle growth and density. Flexing the targeted muscle(s) between sets lets you know the feeling you want to duplicate during the set. With practice, this will strengthen your focus so you can better work that area (Flex pg. 98). If you talk to almost any bodybuilder or physique athlete, they would be able to make almost any muscle they train contract on its own and will be the first to tell you its extremely difficult to hold. If you continue to train your muscles with these so-tension types of exercises you essentially get them accustomed to being in that position which is crucial for stage presence. If you do not practice this before going onto a stage, you tend to be more susceptible to cramps or its difficult o hold the pose for minutes and points will be deducted from shaking or relaxing on the pose. When training or developing a program, each muscle group needs to be trained for this sport. For me personally I have a few weak areas, which is why my individual workout I train deltoids twice a week and only incline chest workouts on there respected day. Also notice the time spread between the deltoid workouts, its Monday and Friday so I am staying within that time frame for optimal muscle repair. The reason I have so much attention on these two muscle groups are because Judges in hysique competition love the big rounded shoulder look, and a full chest. I have a disadvantage in these areas mainly because I am still only 21 so I dont have fully matured muscles yet, and many other competitors are 24 and above. The only way I compensate for this lack of size is to focus on them more than everyone else. Also for the deltoids I have a day that is more heavy, but still at that 12 rep range and another that goes up to 20 reps known as my day. I find it great to have two different variations for optimal muscle growth, especially since it is a small muscle group and s extremely easy to over stress with too much weight in turn causing injury (which I had when I first began lifting at 18). When training this muscle group I focus on the contraction, as well as the time it takes me to fully go through the concentric and eccentric motion. This method insures for me ensures optimal stress without the risk The sport of fitness competing is always plagued for injury, and there will always be that risk. Basically every muscle you train will be susceptible to injury, and there is no way to get around it. However, there are ways to significantly minimize the risks. Workout form has to be at the top of this list hands down, I see many people training and sometimes I cringe Just watching them because it looks as if they will snap their back or tear a muscle. Always make sure to have great form and control with each exercise, and this in my opinion should be applied to any workout you do not Just resistance training. Second thing would have to be the amount of weight you choose to use. I see so many individuals, guys in particular try to do so much damn weight in order to impress that pretty girl, and in turn end up getting hurt and making a fool ut of themselves. Always keep in mind everyone has to start somewhere, and remember no girl is going to care how much weight you can bench. Also perform exercises that are plausible and not these ridiculous crossflt types of movement exercises. I am sorry, but I am not a firm believer in picking up 2001b from the ground and lifting it over your head. That to me is an instant sign for so many different injuries, and not to mention the trainers instructing you allow you to do it with the most horrendous form. Make sure to stretch before working out with warm up sets to et the blood flow throughout the muscle, and after working out with conventional stretches to increase flexibility. Lastly, mind your peers when training because you in fact can injure someone else. I had an incident with a New Years resolution individual that was doing 801b with dumbbell press, and he decides it is too heavy and Just throws them on the ground and it almost bounced onto my foot, which most likely would have broken it. Now with all that being said there are some freak accidents I have seen people with perfect form and mediocre weight have one of heir muscles Just tear, and it is one of the most painful things to witness. I personally had an incident when I was doing incline dumbbell press with 1001b, I performed the exercise without any issues. However when I set the weights down on my knees to put them down, my wrist Just snapped and made this loud popping noise and it hurt terribly. I have no idea what happened and Just took a break for a few weeks because it was painful to grip anything, and it slowly went away for the most part. Since then I use wrist straps and weight belts to help stabilize those parts of my body, which I have found to help. The goal with this program is not only strength gains, but to basically look the best you can physically. It is not all about size, you want to find a nice balance between size, lean muscle mass, and proportionality for your specific division. The program I have set up is the one I currently use for my offseason training (typically the time when there are no shows for 4-6 months). This specific one is to help me gain size, while retaining majority of my lean muscle mass and density so when I have to prepare for a show I will be able to do so with an 8 week program. While prepping for show a lot of my training changes, and I add a few plyometric workouts in as well as interval cardiovascular training 4-6 days a week depending how far out I am from competing. Any type of cardiovascular training I typically do fasted in the morning, difference personally. There are millions of different workouts for different individuals, this specific one I wouldnt say should be used by every competitor since I conformed it to address my weaknesses. For a basic individual who is intermediately experienced with training, and is trying to look great however this would be a great tarting point.

Midieval Church Essay Example for Free

Midieval Church Essay The schism of 1378-1415 involved a division in the church due to existence of two popes. The italians elected a pope as St. Urban VI to succeed St. Peter. The French cardinals at the same time ailed to agree with the italians and elected their own pope called Clement VII. One of the issues leading to the churchs division was the fact that, the christedom couldnt agree on which pope to accept. The second issue was the fact that the two popes were in two different places, ssince St. Urban remained in Rome while Clement VII withdrew to Avignon according to Nelson (1999). In addition, Nelson also argues that there was growing corruption in both papacies,expansion of heresy and the continuation of a cchurch without real leadership or discipline. b. How the schism served to undermine the authority of the popes The papal authority was undermined since financial decisions grew worse during avignon papacy, as there were two papal capitals as well as two administrations. Secular leaders also supported either one pope or the other causing lack of unified support to a single papacy. Furthermore, according to Nelson (1999), theological situation became difficult as the two papal organizations condemned the other. c. New Religious ideas that emerged A number of new religious ideas emerged as a result of the great Schism of 1378-1415. Such religious ideas were as an attempt to resolve the issue of dual papacy and try to regain a single papacy to the church. Some of these religious ideas according to Nelson (1999) included the following: theological faculty of the university of Paris was asked to find a resolve to the problem, the popes were also asked to abdicste for the good of christedom, influential writers decided that monarchy was superior to the church. In addition, Priestly powers were placed in the hands of individuals which later formed the foundation for the refformation of the protestant churches. Furthermore, intellectuals and reformists decided that the churchs sovereighnity rested on its members (Nelson, 1999). This reformists supported their ideas by arguing on the basis of: the scripture according to paul and the early church, History acoording to Constantin and the council of Nicaea among others. d. How the need of the Church to re-establish authority manifested itself in the Fifteenth century. Th e church had a need to re-establish its authority was manifested in the fifteenth century in the following ways; The church formed the council of Pisa according to Nelson (1999) in an attempt to find a solution. This council cardinals decided to depose both pontifs and elected a third in 1408. All the cardinals were excommunicated by the two popes,making matters even worse by creating a third pope. By 14 15 the issues involving the three popes such as increased corruption and heresy led to the Holy Roman Emperor throwing his support behind concilliarists and arranged for another council meeting (Nelson,1999). These attempts were manifested by the church as a way of trying to resolve the issues. In this council,also reffered to as the council of constance, the three â€Å"phantom popes† were deposed in favour of a new pope by the name Martin V. This new pontiff was based at Rome and had a greater responsibility of re-establishing the position of the pope as Gods representative on earth (Nelson, 1999). Works Cited Nelson, L. H. (1999).

Review On The Capital Structure Debate Finance Essay

Review On The Capital Structure Debate Finance Essay Corporations fund their operations by raising capital from a variety of distinct sources. The mix between the different sources, generally referred to as the firms capital structure has attracted considerable attention from academics and practitioners. Debt and equity are raised by firms to finance new investment projects. As such, both of them are sources of funds for the business. Debt usually consists of bank loans either long term or short term whereas equity consists of stocks and bonds. Hence, capital structure refers to the mixture of debt and equity finance used by a company to finance its activities. The correct choice of the mix of debt and equity is questionable. Financial managers problem is to find out the combination of securities that have the greatest overall appeal to investors. Moreover individual firms often change their debt ratios over time, perhaps responding to changes in investment opportunities, agency costs and so on. According to R Charles Moyer, James R. McGuigan and William J. Kretlow (1982), leverage is closely related to capital structure in the financial field. 2.1.1 Importance It is found that there are basically three types of financing decisions taken by firms namely the (i) the distribution of earnings which is the consumption decision, (ii) the capital budgeting decision,i.e, the investment decision and (iii) the capital structure decision. The capital structure decision is fundamental in order to carry out the other two financing decisions, i.e how much cash should the firm lend or borrow in order to carry out the consumption and investment decision. The capital Structure decision is important since profits of various organizational constituencies are maximized as well as the organization is able to deal with its competitive milieu. 2.2 Theories of Capital Structure 2.2.1 Traditional View The traditional view specifies that when a firm uses the right mix of debt and equity, the lowest its WACC, the more it will maximize the firms value due to the tax advantage of debt. If a firm wants to make an optimal capital structure decision, it will have to choose those sources of finance that gives the lowest cost of capital which will in turn lead to the lowest WACC. However, it is to be noted that as gearing increases, the cost of equity and consequently the bankruptcy risk will increase which will in turn lead to an increase in the cost of debt. However, the validity of this theory has been criticized since there is no underlying theory which shows by how much the cost of equity should increase due to increased leverage and by how much the cost of debt should increased due to increased in bankruptcy risk. 2.2.2 Modigliani and Miller Theory In their landmark paper in 1958, the Modigliani Miller Theorem (Modigliani and Miller, 1958, 1961) says that the value of a firm and the investment decisions should be autonomous from its capital structure. In other words, leverage should have no effect on investment decisions. However, the Modigliani Miller Theorem assumes a world with no taxes, information asymmetries or agency costs. Assuming perfect capital markets, they propounded to what is today widely known theory of capital structure irrelevance which means that the capital structure that a company chooses does not affect its value. Later theories argue that leverage clearly can matter due to the effect of taxes, information and agency costs (Myers, 2001). Later, in 1963, Modigliani and Miller took taxation under consideration and proposed that companies should employ as much debt capital as possible in order to achieve the optimal capital structure. Along the lines with corporate taxation, numerous studies also analyzed the case of personal taxes imposed on individuals. Miller (1977) suggests tax rates in the tax legislation of the some of the OECD countries that evaluate the total value of the company. These are the corporate tax rate, the tax rate on income in the form of dividends and the tax rate on interest income. According to Miller, the value of the company depends on the relative percentage and importance of each tax rate, compared with the other two. With respect to theoretical studies, there are two widely acknowledged competitive models of capital structure namely the static trade off model and the pecking order hypothesis. 2.2.3 Tradeoff/ Static Theory This approach presents capital structure as a balance between positive and negative effects of leverage respectively linked to a firms tax advantages and financial risk. The trade off theory introduces into the capital structure debate the benefit of the debt tax shield on one hand and the cost associated with financial distress on the other. The implication of this theory is that each firm has an optimal debt ratio that maximises value, although this level may vary between firms. Moreover, the trade off theory is often further extended to incorporate agency considerations. This is in the spirit of Jensen and Meckling (1976) who note that debt is valuable in reducing the agency costs of equity but at the same time debt is costly as it increases the agency costs of debt. However, there are factors that this theory cannot explain such as why companies are generally conservative in using debt finance, for example, some successful companies such as major pharmaceutical manufacturers continue to operate with low leverage. Furthermore, this theory cannot explain why leverage is negatively related to profitability as reported by Myers (1993), Titman and Wessels (1988) and Fama and French (2000). 2.2.4 Pecking Order Theory Pecking Order Theory is considered as one of the most influential theories of capital structure According to Myres (1984), this theory advocates an order in the choice of finance due to different degrees of information asymmetry and related agency costs embodied in distinct sources of finance. As such, retained earnings are used first since they constitute the cheapest means of finance, hardly being affected by any information asymmetry. Second, debt is used as there is low information asymmetry due to fixed obligations acting as an effective monitoring device. Finally, external equity is used only as a last resort as it conveys adverse signaling effect as explained by event studies. This theory also claims that there is no optimal capital structure that maximises the firms value. The attraction of interest tax shields and the treatment of financial distress are therefore assumed to be second order of importance, because debt ratios change when there is an imbalance of internal cash flows net of dividends and real investment opportunities. Profitable firms work down to low debt ratios, while those whose viable investment opportunities exceed internally generated funds tend to borrow more and more. The pecking order form of financing is also influenced by information asymmetries which are where investors make inferences about a firms prospects based on managements financing decisions. A positive impact on the share price only occurs if management chooses to refinance with debt rather than equity, because the firms prospects are then viewed as being good (i.e. by investors). Managers thus avoid the alternative scenario (a decline in the share price due to new equity issues) by maintaining a borrowing capacity or financial slack that consists of retained earnings and/or marketable securities. 2.2.5 Agency Theory Jensen and Meckling (1976) pinpoint the existence of the agency problem which arises due to the conflicts either between managers and shareholders (agency cost of equity capital) or between shareholders and debt holders (agency cost of debt capital). Promoters with major shareholding usually consider the impact of raising funds via equity financing. However, more equity shareholders would imply a dilution of control. Therefore, in order to retain control over management, some firms prefer debt financing. Theory supports that leverage matters due to the effect on agency costs. Leverage is predicted to reduce the agency costs from the manager-shareholder conflict; thereby mitigating the investment inefficiency resulting from this conflict. The Free Cash Flow theory (Jensen, 1986) suggests that debt reduces the agency cost of free cash flow. He also argues that, since debt commits the firm to pay out cash, it reduces that amount of free cash flow available to managers to engage in self interest activities. Debt financing ensures that the management is disciplined to making efficient investment decisions which will maximize the firms value and that they are not pursing individual decisions which will increase the profitability of bankruptcy. The mitigation of the conflicts between managers and shareholders constitutes the benefit of debt financing. Furthermore, Jensen argues that debt also imposes strong control effects on managers. Debt holders can exert a stronger control of the firm than shareholders. A promise to shareholders to payout a certain amount in dividends is considered weak since it is not binding (dividends can be reduced in the future). Debt creation, however, forces managers to effectively bond their promise to pay out future cash flows. The debt holders have the right to take the firm to bankruptcy court if the firm cannot make its debt service payments. The threat caused by failure to make debt service payments serves as an effective motivation force for managers to make their firms more efficient. Thus, through the reduction of free cash flows and control effects, leverage is presumed to mitigate the manager-shareholder conflict and overinvestment. According to Harris and Raviv (1990), the role of debt in allowing investors to generate information useful for monitoring management and implementing efficient operating decisions. Debt-holders use their legal rights to force management to provide information. The optimal amount of debt is determined by trading-off the value of information and opportunities for disciplining management against the probability of incurring costs. Monitoring costs would be incurred by debt-holders to ensure that the managers do not increase the risk of the firm by investing in risky projects. However, by investigating in risky projects, free cash flows can fluctuate and debt holders might not be paid. To prevent this, banks will have to monitor the firm and will thus impose a number of conditions, for example, the firm will keep a particular liquidity ratio as decided by the banks analysis. Subsequently, the cost of debt will increase since it will include the agency costs. As a result WACC will increa se and eventually the value of the firm will decrease. Hence, the firm will not be able to take maximum of debt since the cost of debt will increase because of the monitoring costs that have to be adhered to. Therefore, firms with relatively higher agency costs due to the inherent conflict between the firm and the debt-holders should have lower levels of outside debt financing and leverage. 2.2.6 The Signaling Hypothesis The Signaling Theory is based n the assumption that managers possess superior knowledge as insiders as opposed to outside investors who know much less about the economic health of a firm. This hypothesis suggests that managers may choose financial leverage as means to send signals to the public about the future of the company. Ross (1977) claimed that greater average financial leverage is used by managers to signal an optimistic future about the firm. Furthermore, Leland and Pyle (1977) argued that an owners willingness to invest in his own project conveys a positive information to the market since it can be used as a signal for project quality. 2.2.7 Bankruptcy Cost Arguments against/For debt (put I table in Appendix in case in excess)

Holistic Design Essay -- Industry Industrial Essays

Holistic Design Thesis: Design is the root of action; if we can creatively construct our products and systems with purpose and understanding of the processes and side effects of these systems, we can improve our relationship to the natural world. Introduction to Industrial Design Our modern lives are full of manufactured products. Nearly everything that surrounds us in our day-to-day lives is born of intense industrial processes, yet rarely do we think of the systems that support our lifestyles. Finding a single action in a day that does not somehow depend on fossil fuels is nearly impossible. Everything we use, eat, or come in contact with has either been shipped or manufactured (or both) far away from where we live, and arrives at our door via processes that gobble up mounds of natural resources (Chiras, 2000). Because of the affluence of our lifestyle, we do not see the effects of these processes, and thus we rarely consider the long-term sustainability of our daily actions. While humans have always survived by our ability to use our surroundings, the industrial revolution increased our power to thrive, also increasing the size of our "footprint" (amount of land or resources required to sustain us). The machines that arose (and the knack for utilizing the energy in fossil fuels) during the industrial revolution greatly increased the output of manufacturing companies, also increasing the inputs of raw materials (Chiras, 2001).

kamehameha the third Essay -- essays research papers fc

Kauikeaouli was born on August 11, 1813 on the Big Island of Hawaii. He became king at age 11 when his older brother Liholiho died, who ruled as Kamehameha II. For 14 years of his reign Kauikeaouli was guided by Kaahumanu and Kinau. At age 25, he took on the responsibilities of kingship by himself as Kamehameha III. (The Reign of Kamehameha III Website) Kauikeaouli’s reign of thirty years was filled with change and accomplishment. Kamehameha III’s reign would be a desirable time to live in because of the small population, religious freedom, and the equality for all Hawaiians.   Ã‚  Ã‚  Ã‚  Ã‚  One of the biggest changes was the decrease in population of the native Hawaiians. When Kauikeaouli became king in June 1825, the native population was about 150,000, which is half of the Hawaiian population at the time of Captain Cook’s arrival in 1778. (Mrantz) Prior to 1778, Hawaiians had lived in isolation for a thousand years, practicing an ancient system of health and hygiene in perfect balance with the environment. During Kamehameha III’s reign, the small pox arrived, which decreased the population by half again. (The Reign of Kamehameha III Website) The reason why so many Hawaiians died was because they had no experience with contagious diseases and neither did their grandparents before them. When smallpox came they regarded it with curiosity rather than with fear. Few of the chiefs died, and not one of the member’s of the Legislation had caught the disease even tho...

Quest for Identity in Maxine Hong Kingstons Autobiography, The Woman W

Quest for Identity in Maxine Hong Kingston's Autobiography, The Woman Warrior Maxine Hong Kingston's autobiography, The Woman Warrior, features a young Chinese-American constantly searching for "an unusual bird" that would serve as her impeccable guide on her quest for individuality (49). Instead of the flawless guide she seeks, Kingston develops under the influence of other teachers who either seem more fallible or less realistic. Dependent upon their guidance, she grows under the influence of American and Chinese schools and the role models of Brave Orchid, Fa Mu Lan, and Moon Orchid. Her education by these counselors consequently causes her to abandon her search for an escort, the bird to be found somewhere in the measureless sky, and she begins to look inside herself for "the ideograph 'to fly'" (Kingston 35). The new song Kingston finally creates with her "talk story" of Ts'ai Yen, verifies her optimistic distinction from her educators, cultural norms, which have indoctrinated and restricted her childhood. During much of her childhood, Kingston goes to the "American School" during the day and the "Chinese School" in the evening as she filters the conflicting material given in each of these environments to determine what works in her Chinese-American life. In attending the American school, Kingston discovers American ideologies of loquaciousness and arrogance. From the influence of their American schoolmates Kingston and her siblings "never said, 'Oh, no, you're too kind. . . . I'm stupid. I'm ugly.' They were capable children. . . . But they were not modest" (Kingston 134). The children expected their Chinese parents to join in their arrogance, and Kingston proudly tells her mother, "I got straight A's, Mama" (45). H... ...d not the measureless sky, her voice begins to sing a distinctly Chinese-American song. Kingston sings just as Ts'ai Yen "sang about China and her family . . . [from] savage lands," and speaking of her newly found identity, established in America but conceived in China, Kingston decides, "It translated well" (Kingston 209). Works Cited Hunt, Linda.

Synthesis of Aspirin

Abstract: The purpose of this lab is to synthesise acetylsalicylic acid (aspirin) by creating a reaction between acetic anhydride and salicylic acid. This was be accomplished through the use of recrystallization. Acetic anhydride and salicylic acid are mixed together, and then acidified by the addition of a few drops of concentrated sulfuric acid, which catalyzed the reaction. The percent yield is calculated to determine the effectiveness of the reaction in preparing the desired product (aspirin).The limiting reactant of the equation was salicylic acid. After the limiting reactant was determined, the theoretical yield of aspirin was calculated at approximately 1.97g. The actual yield was only around 0.67g, producing a percent yield of 34.3%. These results show that the methods used were only partially successful at achieving the goal of the experiment (synthesising aspirin). The findings showed that acetylsalicylic acid can be produced through a reaction between salicylic acid and ac etic anhydride, but that a much lower yield will be produced. A higher yield could surely be achieved if several sources of error were to be eliminated.Introduction: Acetylsalicylic acid is commonly used to alleviate minor aches and pains (Wikipedia, Aspirin, 2013). The active metabolite ingredient in acetylsalicylic acid (aspirin) is salicylic acid (Wikipedia, Salicylic acid, 2013), which was first discovered by Edward Stone in 1763 (Wikipedia, Aspirin, 2013).Salicylic acid is toxic in large quantities but in small doses can be useful for food preservatives and as an antiseptic. Other than being used in the production of aspirin, acetic anhydride is used to convert cellulose to cellulose acetate, a key component in photographic film and other coated materials (Wikipedia, Acetic anhydride, 2013). Sulfuric acid has many applications, such as pigments, explosives, lubricants, batteries, antifreeze, and detergents. In the synthesis of aspirin, sulfuric acid is also used as a catalyst t o speed up the reaction (Wikipedia, Sulfuric acid, 2013).Limiting reactants are important in chemical reactions because a reaction cannot proceed without all of the reactants. That is to say, a reaction can  only occur until one reactant is used up (Kirk, 2013). Percent yields are related to limiting reactants because the formula to solve for percent yield includes theoretical and actual yield. The theoretical yield is the amount of a product formed when the limiting reactant in completely consumed, and is the maximum amount that can be produced from the amount of reactants used in the reaction. The theoretical yield is rarely obtained because of sources of error, side reactions, or other complications. The percent yield is the actual yield of a product given as a percentage of the theoretical yield (Kirk, 2013).Purpose:How can one prepare aspirin through a reaction between salicylic acid and acetic anhydride?Apparatus:(2) 250 mL beaker 10 mL graduated cylinder Filter paper Funnel support Hot plate 25 mL graduated cylinder 50 mL Erlenmeyer flask Eyedropper pipette Funnel 100 mL beaker Wash bottleMaterials:Boiling chips (calcium carbonate) Acetic anhydride 18M sulfuric acid Ethanol Salicylic acid Distilled water IceMethod: 1. Prepared a water bath by half-filling a 250 mL beaker with water and heating it on a hot plate to until it was near boiling. Placed a few boiling chips in the beaker to prevent bumping if the water began to boil. 2. Weighed out 1.5g of salicylic acid on a piece of filter paper. Recorded the weight on the data sheet. Transferred the salicylic acid to a 50 mL Erlenmeyer flask. 3. Measured out 5.0 mL of acetic anhydride in a graduated cylinder from the fume hood. Recorded the volume of acetic anhydride used on the data sheet. Poured the acetic anhydride into the 50 mL Erlenmeyer flask containing the salicylic acid.4. Took the Erlenmeyer flask to the fume hood and added 5 drops of concentrated sulfuric acid to the mixture. 5. Mixed the solut ion and placed the Erlenmeyer flask in the water bath for about 10 minutes, making sure the Erlenmeyer flask did not tip in the water bath. 6. After the 10 minutes elapsed, added 2 mL of distilled water with an eyedropper carefully to avoid splatter. Waited 6 minutes, during which time an ice water mixture was prepared in another 250 mL beaker. 7. After the 6 minutes elapsed, 10 mL of distilled water was added to the Erlenmeyer flask and placed in the ice water, avoiding getting any of the ice water in the Erlenmeyer flask. A precipitate formed as the solution cooled. Used the â€Å"scratching† method, in which the bottom of the Erlenmeyer flask is scraped, to speed up the process of precipitate formation.8. Prepared a piece of filter paper in a filter funnel and filtered off the precipitate from the Erlenmeyer flask solution. After the liquid drained through the filter paper, washed the filtrate with two 10 mL portions of cold distilled water. When all the water had drained through, the filter paper was removed, and the solid (impure aspirin) was scraped into a dry 100 mL beaker using a clean scoopula.Recrystallization9. Measured out 5 mL of ethanol from the fume hood in a graduated cylinder, and added it to the 100 mL beaker containing the solid aspirin. Swirled the beaker to dissolve as much of the solid as possible, then placed the beaker on the hot plate until the solid completely dissolved. 10. After the solid  dissolved, added about 15 mL of distilled water. Prepared another ice water mixture in the 250 mL beaker and placed the 100 mL beaker in the ice water. Waited about 10 minutes. 11. Weighed a piece of filter paper and recorded it on the data sheet. Prepared the filter paper in a funnel and filtered off the precipitate. Rinsed the dirty apparatus thoroughly with lots of water. After all of the water was filtered through, left the filter paper to dry until the next class. 12. Weighed the piece of filter paper with the aspirin on it. Recorded the weight on the data table. Discarded the aspirin.Results: Overall Findings: When the salicylic acid and acetic anhydride were mixed, a white, powdery solution formed. When the sulfuric acid was added, a clear solution formed that produced heat. After heating, then cooling and scratching the solution, a white precipitate formed. The moisture in the precipitate was filtered overnight and what was left over was the desired product, aspirin.Qualitative Data: The boiling chips (calcium carbonate) were white, opaque crystals. The acetic anhydride was a clear solution with a vinegar-like odour. The salicylic acid was a find, white solid powder. The ethanol was a clear solution with an odour similar to strong alcohol. The sulfuric acid was a clear solution with a strong odour when heated. The aspirin (acetylsalicylic acid) was a white, solid powder.When the acetic anhydride and salicylic acid were mixed, they produced a white, powdery solution. When the sulfuric acid was added to this s olution, it turned clear and was warm. Upon heating the solution and adding water, puffs of smoke were produced. When the solution cooled and the â€Å"scratching† method was used, a white precipitate formed.Quantitative Data: Density (Table #1) Substance Density Acetic anhydride 1.08 m/LVolume (Table #2) Substance Volume Acetic anhydride 5.0 mLMolar weight (Table #3) Substance Molar weight Salicylic acid 138.12 g/mol Acetic anhydride 102.09 g/mol Acetylsalicylic acid 180.16 g/mol Weight (Table #4) Substance Weight Salicylic acid 1.51 g Acetic anhydride 5.4 g Empty filter paper 1.27 g Filter paper and aspirin 1.946 g Aspirin 0.676 gPercent Yield (Table #5) Substance Percent Yield Aspirin 34.3%Analysis: Determine whether the limiting reactant is the salicylic acid or the acetic anhydride. First, convert both masses to moles. 1 mole is equal to the molar mass of a substance; therefore, the grams of acetic anhydride and grams of salicylic acid must be divided by their molar mass es respectively.Molar mass of acetic anhydride = 4(12.01) + 6(1.008) + 3(16) = 102.088g Molar mass of salicylic acid = 7(12.01) + 6(1.008) + 3(16) = 138.118 g Acetic anhydride: 5.4g C4H6O3 x 1 mole C4H6O3 l= 0.052895541 moles C4H6O3 102.088g C4H6O3Salicylic acid:1.51g C7H6O3 x 1 mole C7H6O3 = 0.01093268 moles C7H6O3 138.118 g C7H6O3Since both acetic anhydride and salicylic acid have a coefficient of 1, the smaller number is the limiting reactant. Therefore, salicylic acid is the limiting reactant of the reaction. Next, calculate the theoretical yield of aspirin by converting the mass of the limiting reactant to grams of aspirin. 1.51g C7H6O3 x 1 mole C7H6O3 x 1 mole C9H8O4 x 180.154 g C9H8O4138.118 g C7H6O3 1 mol C7H6O31 mol C9H8O4 = 1.969566168g AspirinUsing the theoretical yield and the actual yield (from the data table), calculate the percent yield.Percent yield = Actual yield x 100 = l 0.676g l x 100 = 34.3% Theoretical yield1.969566168gDiscussion: Sources of error that were pos sibly present in the synthesis of aspirin lab are an improperly calibrated balance, an inaccurate hot plate, contamination  of the substances, age of the substances, or contamination of the glassware. Inaccurate calibrations of the hot plate or balance could have shown higher or lower quantitative data which would have affected the results by producing either a higher or lower percent yield. A contamination of the substances used or the glassware could have caused the substances to react differently with each other, again causing the percent yield to change depending on how the contamination affected the substances by producing a higher or lower percent yield.Another source of error could have been due to the transport of the aspirin from the Erlenmeyer flask after cooling to the funnel to be filtered. Some of the aspirin may have been lost or left behind and that would have showed a lower percent yield. The accuracy of this lab could be improved with more precise equipment, allow ing the experimenter to be more confident in the accuracy of the measurements obtained. While the aspirin was left overnight to allow time for the moisture to be filtered out, the air could have been a contaminant.A way to get rid of the source of error would be to keep the samples in a more isolated area where there is a smaller chance of contamination. Aspirin has many real-life applications. It is a pain reliever and a non-steroidal anti-inflammatory (NSAID). It has become very common as an antiplatelet to prevent blood clot formation and is used to prevent heart attacks and strokes. It has been present for over one hundred years and is one of the most widely used medications in the world. Conclusion:The main objective of the synthesis of aspirin lab was so produce aspirin (acetylsalicylic acid) through the reaction of salicylic acid and acetic anhydride. The methods used included recrystallization and scratching to produce a precipitate, which was then filtered to remove any exc ess moisture. The results displayed a percent yield of 34.3%, from a theoretical yield of about 1.97g of aspirin and an actual yield of approximately 0.68g of aspirin. Upon completion of the lab, analysis, and calculations, it is evident that the synthesis of aspirin is possible using these methods but that the yield will be relatively low.

Relating Moles to Coefficients of a Chemical Equation Essay

Introduction: The definition of a mole is Avogadro’s number (6.02 x 1023) of particles (atoms, molecules, ions, electrons etc.). Moles are a very important part of chemistry especially in stoichiometry since it is part of many other calculation quantities and formulas including molar mass, solution calculations and gas volume calculations. The mole is also used in chemical reactions and equations to calculate the amount of reactant needed to react completely with another reactant or to calculate the product produced from the amount of reactant provided and vice versa. This is done by using the ratio of the coefficients in a balanced equation. This ratio of coefficients is also known as the mole ratio. In the following experiment, a simple displacement reaction would occur from the reaction of an aqueous solution of copper (II) sulphate and zinc powder. Zn (s) + CuSO4 (aq) à ¯Ã‚ ¿Ã‚ ½ ZnSO4 (aq) + Cu (s) This reaction would be set up to allow the zinc to be the limiting factor therefore react completely, in order for that to happen, copper (II) sulphate would be in excess. As zinc is the limiting factor, it will be used to calculate the expected amount of copper produced from the 1 to 1 mole ratio of zinc and copper from the balanced equation above. Aim: To find the mole ratio of a reactant to a product in a chemical reaction . Apparatus: – Balance – Bunsen Burner – Two 150 cm3 Beaker – Glass Stirring Rod – Tripod – Gauze – 100 cm3 Graduated Cylinder – Goggles – Heat Proof Mat – Pure Distilled Water – Tongs – Balance to 0.01 g Reagents: – Copper (II) Sulphate Crystals – Zinc Powder Method: 1. Weigh the mass of a clean, dry 150 cm3 beaker. Then weigh out 7.0 g of copper (II) sulphate using the beaker 2. Add 50.0 cm3 of pure distilled water into the beaker and heat the solution gently until all the copper (II) sulphate has dissolved 3. Determine the mass of the second clean, dry 150 cm3 beaker. Then weigh out as accurately as possible, 1.30 g of zinc powder using the beaker 4. Record the mass of the beaker and the zinc powder in the results table, nearest to 0.01 g 5. Slowly pour the copper (II) sulphate into the beaker containing the zinc. Stir continuously for 1-2 minutes 6. Leave the beaker for 10 minutes while the reaction continues. Record your observations 7. When the copper has settled, pour out the light blue liquid. 8. Add 10 cm3 of pure distilled water into the beaker. 9. Leave it for 10 minutes again and pour out the liquid again 10. Repeat steps 8 and 9, two times 11. Place the beaker in the oven to dry for 24 hours 12. Remove the beaker from the oven and determine the mass. Results: 1. Mass of empty 250 cm3 beaker 97.37g 2. Mass of the 250 cm3 beaker and copper (II) sulphate 104.37g 3. Mass of copper (II) sulphate 7.0g 4. Mass of empty 150 cm3 beaker 98.66g 5. Mass of 150 cm3 beaker and zinc powder 99.96g 6. Mass of zinc powder 1.30g 7. Mass of the 150 cm3 beaker and copper formed (after drying overnight) 98.78g 8. Mass of copper 1.41g Calculations: 1. Number of moles of copper produced n = = = 0.0222 mol 2. Number of zinc moles reacted n = = = 0.0199 mol 3. Zn : Cu 0.0199 mol : 0.0222 mol 1 : 1 4. Mass of copper expected = n(Cu) = 1 x 0.0199 = 0.0199 mol m = nM = 0.0199 x 63.55 = 1.26 g 5. Percentage Yield: x 100 = 89.4% Conclusion: The mole ratio from calculation 3 is approximately 1 to 1, same as the expected mole ratio from the balanced equation. The expected mass of copper is 1.26 g but 1.41g of copper was weighed out therefore, the percentage yield of the above experiment is 89.4%. This is mostly caused by the impurity of the copper since there might be a small amount of leftover zinc sulphate in the beaker. Evaluation: From the experiment above, some things could have been done better to achieve a higher percentage yield. The glass rod should’ve been dipped into water before stirring the copper (II) sulphate and zinc in order for no copper to attach to the glass rod after stirring. More importantly, I could have improved and made this experiment more accurate by rinsing the copper more thoroughly so no zinc sulphate would be left in the beaker.

Health Status Impact Of Income Health And Social Care Essay

The economic inquiries of my documents as a group involve the insouciant consequence of income ( or state ‘s income ) on wellness position of persons. The policy relevancy of these inquiries suggests that, if truly income affects wellness position, so the authorities should use income and wellness policies that are designed to back up individuals with low income which in bend alleviates the effects of low income ; hapless wellness position being a cardinal effect in this paper. The execution of such policies will enable low income individuals gain entree to wellness attention services. Possible policies include income policies such as employment insurance – that offers impermanent fiscal aid to those that are unemployed while they look for work, public assistance aid – that offers fiscal assistance to those in demand of basic necessities every bit good as wellness policy, exactly public wellness insurance such as Medicaid – for low income and destitute peop le. In this paper, I will be turn toing two major inquiries. The initial inquiry that I will turn to in this research is, â€Å" the consequence of high income and low income on the wellness position of persons severally † . It will help to verify whether individuals with really low income are at higher hazard of sing deteriorating wellness and frailty versa. The following inquiry to be addressed is the way of causality between income and wellness – income to wellness position or wellness position to income degree? This paper is structured as follows: Section two reviews the article â€Å" The Casual Effect of Income on Health: Evidence from Germany Reunification † by Paul Frijters et al. The writers used a big scale natural experiment created by the â€Å" falling of the Berlin Wall † and the attendant reunion of Germany to analyze the insouciant consequence of income alterations on the wellness satisfaction of East and West Germans. The 3rd subdivision looks at the findings from the article, â€Å" Estimating the Effect of Income on Health and Mortality Using Lottery Prizes as an Exogenous Source of Variation in Income † by Mikael Lindahl. This article builds on the huge literature that has established a strong positive relation between income and wellness position and a negative relation with mortality. The 4th subdivision reviews the article, â€Å" Does Money Protect Health Status? Evidence from South African Pensions † by Anne Case. The writer uses pension income as an instrument to analyze the relationship between income and wellness. The 5th subdivision reviews the article by Jerome Adda et Al titled, â€Å" The Impact of Income Shocks on Health: Evidence from Cohort Data. The writer surveies the consequence of income dazes on wellness for a prime-aged population. Section six examines the findings from the article, â€Å" Wealthier is Healthier † by Lant Prichett and Lawrence H. Summers. The writers estimated the effects of income utilizing cross-country, time-series informations on wellness and income per capital. The concluding subdivision of this paper provides a sum-up of the decisions from the articles mentioned above every bit good as unreciprocated inquiries and suggestions for future research. The major countries of treatment will come from the data point, natural experiments and econometric theoretical accounts that these articles use in order to reply inquiries about the impact of income on wellness. Furthermore, the strengths and failings of each article would be presented in each subdivision ; subdivision two to subdivision six. Section 2: Frijters, P. , Haisken-DeNew, J.P. , & A ; Shields, M.A. 2005, September. â€Å" The Casual Consequence of Income on Health: Evidence from Germany Reunification. † Journal of Health Economics, Vol. 24, no. 5: 997-1017. This article investigates the causal consequence of income alterations on the wellness satisfaction of East and West Germans in the old ages following reunion. The policy relevancy in this article affirms that understanding the causal pathways between income and wellness is critical for policy design aimed at bettering general wellness or contracting wellness inequalities in society ( Frijters, 2005 ) . The cardinal literature on which this article builds is the literature that has attempted to set up the insouciant consequence of income on wellness utilizing both cross-sectional and longitudinal study informations. The cardinal findings in this literature are that there is a weak nexus between wealth, income and wellness ( Frijters, 2005 ) . The writers used a big scale natural experiment created by the â€Å" falling of the Berlin Wall † and the attendant reunion of Germany in 1990, in order to better set up the causal consequence of income changed on wellness satisfaction ( Frijters, 2005 ) . It was widely acknowledged that the falling of the Berlin Wall was wholly unexpected by the huge bulk of East and West Germans, and resulted to a big income transportations to virtually all of the population of East Germany ( Frijters, 2005 ) . The information beginning used by the writers is the German Socio-Economic Panel ( GSOEP ) between 1984 and 2002 which contains the GSOEP for East Germans and West Germans from 1990 to 2002 and 1984 to 2002 severally. The GSOEP sampled persons, aged 18 and over ; this sample consisted of 46,953 individuals per twelvemonth observations ( 22,641 males ; 24, 492 females ) on 6198 East Germans and 176,770 individuals per twelvemonth observations ( 86,773 males ; 24,492 females ) on 20,617 West Germans ( Frijters, 2005 ) . The methods of analysis used are fixed-effects ordinal calculator – to command for unseen single heterogeneousness that might find both income and wellness satisfaction ; and causal decomposition technique to account for panel abrasion that allows for the designation of alterations as respondents drop out of the sample and new respondents enter the sample ( Frijters, 2005 ) . The equation used in the fixed-effects ordered logit theoretical account is as follows: H*it = Xi, tI? + I?t + fi + I µit Hit = k i H*it I µ [ I?k, I?k+1 ] where H*it is the latent wellness satisfaction ; Hit is the ascertained wellness satisfaction ; Xit is the discernible time-varying features ; I?k denotes the kth cut-off point for the classs ; I?t represents the unseen time-varying general fortunes ; fi is an single fixed features ; and I µit is the error term that is extraneous to all features. In the econometric model, the endogenous variable, H I µ { 0, †¦ 10 } , represents an ordinal index of wellness satisfaction as evaluated by the person. This step is available for a set of persons indexed by I, where I is a figure from 1 to 10 ; each figure is observed over some immediate subset of old ages indexed T, where T = 1, †¦ ..T ( Frijters, 2005 ) . The drawback of this theoretical account is that it uses a little sum of the entire information available in the sample because the theoretical account reduces all the ordinal wellness satisfaction observations to ( 0, 1 ) . The importance of this theoretical account is tha t it attempts to explicate in which old ages an person had a comparatively high wellness satisfaction position. A positive consequence of income would so intend that persons ‘ comparatively fitter periods occur when their incomes are comparatively high ( Frijters, 2005 ) . The causal decomposition theoretical account decomposes the alterations in the expected latent wellness satisfaction for males and females individually in the post-reunification period and besides in the pre-unification period for West Germans utilizing the estimations from the fixed-effects theoretical accounts. The entire alterations in latent wellness satisfaction was decomposed into alterations in: existent household income, job-related variables such as pregnancy leave, unemployed and unemployed, household related variables such as matrimonial position, family wellness related variables such as decease of partner, unseen single effects distribution and the unseen mean variables such as clip parametric quantities ( Frijters, 2005 ) . The major consequence from this probe is that increased income leads to better wellness satisfaction, but the quantitative size of this consequence is really little when alterations in current income and a step of lasting income are used ( Frijters, 2005 ) . The policy deduction of these consequences is that addition in household income improved wellness satisfaction. The strength in this article comes from the panel informations that is used ; the GSOEP covers a big sample of persons and it is a longitudinal/panel information since it compares single differences over clip which in bend strengthens the external cogency of this survey. A longitudinal information is utile in foretelling long-run or cumulative effects which are usually difficult to analyse in a cross-sectional survey. In add-on, the sample is taken over a long clip period – 19 twelvemonth period which increases external cogency. Besides, the methods of analysis used are really comprehensive which makes it one of the strengths ; the writer makes usage of the fixed-effects ordinal calculator to command for unseen single heterogeneousness and causal decomposition technique to account for panel. Persons in the survey were besides categorized based on socio-demographic features. Another strength identified is within the external cogency of the survey since the writer examines a alo ne period – Germany reunion. The Germany reunion was an ideal scene to detect the consequence of income on wellness satisfaction since this action was wholly unanticipated by the Germans. Strengths were besides found within the internal cogency of the survey because this survey entails an first-class natural experiment, hence there were no prejudices in the manner people behaved. Failings, on the other manus come from the self-reported wellness positions which might make prejudice since it would be hard to deny or corroborate many claims. Last, the consequences of this survey can non be applied to other states or metropoliss since the survey was done on a alone period in Germany. Section 3: Lindahl, M. 2005. â€Å" Estimating the Effect of Income on Health and Mortality Using Lottery Prizes as an Exogenous Source of Variation in Income. † Journal of Human Resources, Vol. 40, no. 1: 144-68. The economic inquiry that is studied by the writer is the consequence of income on wellness and mortality by utilizing information on pecuniary lottery awards to make exogenic fluctuation in income. The policy relevancy of this article involves separating an association from a insouciant relation which suggests taking in to account the effects of income policies on the wellness of persons. The cardinal literature on which this article builds is the huge literature which has established a strong positive relation between income and wellness position and a negative relation with mortality. This survey comprises of an experimental survey in which the writer uses informations sets from the Swedish Level of Living Surveys ( SLLS ) for 1968, 1974, and 1981. The SLLS follows persons across moving ridges so that many persons are included in all old ages and new persons are frequently added in each moving ridge to keep a representative sample ( Lindahl, 2005 ) . An advantage of utilizing this information set is that they contain extended inquiries on wellness and the matched informations on income and decease day of the months from administrative registries ; it besides contains a inquiry on the sum of money won on lotteries ( Lindahl, 2005 ) . The writer uses OLS and IV theoretical accounts as the method of analysis to gauge the arrested developments of wellness on mean lottery, mean income and other covariates. The writer estimated the arrested developments of wellness in 1981 on the mean lottery award from 1969 to 1981 utilizing the undermentioned equation: Hi81 = I ± + I?Li81,13 + I?'Xit + A†¹i81, where Hi81 represents the assorted steps of hapless wellness in 1981 for single I ; Li81,13 is the mean lottery award in 1969 to 1981 ; Xit is a vector of demographic and household background variables every bit good as socioeconomic variables measured in 196 ; A†¹i81 denotes a random mistake term. The writer controlled for socio-economic variables measured every bit early as 1968 and non subsequently because variables measured subsequently are potentially endogenous with regard to lottery awards before 1969 to 1981 ; the dependant variable is in bad wellness ( Lindahl, 2005 ) . Subsequently, the writer estimated the OLS and IV arrested developments of wellness in 1981 on the logarithm of mean income in 1967 to 1981 utilizing the equations below: ( 1 ) Hi81 = I ± + I? log ( Ii81,15 ) + I?'Xit + I µi81 ( 2 ) log ( Ii81,15 ) = aO + a1 Li81,13 + I„'Xit + vi81, where Ii81,15 is the mean income in 1967 to 1981 ; I µi81 and vi81 are the random mistake footings. Harmonizing to Lindahl, the grounds for bespeaking Hi81 as a map of log income are that wellness variables and log income frequently are about linearly related and that the use of log income facilitates reading. The magnitude of the estimated income consequence is I? . Therefore if I? = – 1, so a 10 per centum addition in income outputs approximately 10 per centum of a standard divergence addition in good wellness, on norm ( Lindahl, 2005 ) . The chief consequences of this survey are that higher income causally generates good wellness ; and income is non protective against bad wellness for older people. The writer besides found out that income causally produces fewer symptoms of hapless mental wellness and decreases the opportunity of a individual being overweight ( Lindahl, 2005 ) . The policy deductions of these consequences is that income redistribution had a positive consequence on wellness position. After a clear reappraisal of this article, it is evident that it exhibits both strengths and failing. The strengths of this article prevarication in the beginning of informations utilised ( SLLS ) since it follows persons across moving ridges so that many persons are included in all old ages and new persons are frequently added in each moving ridge to keep a representative sample. Strengths are found in the information beginning used since it contained extended inquiries on wellness and matched informations on income and decease position from revenue enhancement registries. Another strength identified is the method of analysis used – the manner in which mean disposable household income is calculated, the appraisal of wellness arrested developments on mean lottery award every bit good as the OLS and IV appraisal of wellness arrested developments on the logarithm of mean income. The writer besides controlled for several confusing variables such as the socio-economic variables an d the standardised index of bad wellness in order to forestall prejudice in appraisal. One major failing of this article is found in the internal cogency of the survey in that the informations beginning covers a little clip period – merely three periods ; hence it is difficult brand generalisations. Another failing is that the figure of single in the survey is unknown ; therefore it is hard to besides do generalisations. Similar to other articles, failings besides come from the self-reported wellness positions. Section 4: Case, A. 2001, October. â€Å" Does Money Protect Health Status? Evidence from South African Pensions. † National Bureau of Economic Research, Inc, NBER Working Documents: 8495, 1-32. The writer quantifies the impact of a big, exogenic addition in income on wellness position that is associated with the South African province old age pension. The province old pension was originally intended as a safety cyberspace for Whites who reached retirement age without an equal employment-based pension ; pension payments were bit by bit equalized across all racial groups during the decomposition of the Apartheid government in the early 1990s. This province old age pension constitutes an first-class natural experiment in South Africa because those who received this income ne'er expected it when they were younger and when the apartheid was still strong, therefore it represents an exogenic addition in income similar to lottery profitss ( Dr. Dooley ) . A 3rd of families in South Africa have at least one pensionary and the return up of the pension is really high. On norm, adult females aged 60 or above and work forces aged 65 or above by and large receive the full sum of the pens ion if they do non hold a private pension. The take-up rate for the province pension is approximately 80 % for inkinesss and coloured. For Whites, who are by and large covered by private pensions, the take-up rate is less than 10 % . The policy relevancy of this article involves pensions that are designed by the authorities for individuals that have retired or are of old age when they are no longer gaining a regular income from employment. The cardinal findings in the literature on which this paper builds is that socioeconomic position has a big impact on wellness results. The information beginning used is the Langeberg study which asks information on persons ‘ wellness, mental wellness, societal connection and economic position. This study was run in 1999 on racially stratified random sample – inkinesss, coloureds and Whites of 300 families ( 1300 persons ) in the Langeberg wellness territory ( Case, 2001 ) . The information used is cross-sectional one since it interviews persons at one point in clip ( 1999 ) to compare differences amongst them. The study was developed over a four twelvemonth period and was the joint merchandise of assorted research workers at the University of Capetown, South Africa that included economic experts, geriatrician, doctors and public wellness experts ( Case, 2001 ) . The study consisted of four faculties ; the first faculty was a family faculty which collected information from the individual in the family identified as â€Å" most knowing about how income is spent by the family † . The following facul ty was for younger grownups, aged 18 to 54, which collected information on work histories, net incomes, wellness position and societal connection. The 3rd faculty was for older grownup, aged 55 or greater which asked extra inquiries on the activities of day-to-day life and about South Africa ‘s alone old age pension. The 4th faculty collected information on vaccinums from kids ‘s wellness cards and information on breastfeeding patterns every bit good as the weights and highs of the kids ( Case, 2001 ) . The writer uses ordered probits of self-reported wellness position as a method of appraisal to analyze the consequence of pension income on wellness position. Ordered probits fundamentally assumes that rankings of wellness positions are meaningful but central differences are non meaningful ( Dr. Dooley ) . For illustration, if an single rates his wellness on a graduated table of 5 and another rates his wellness on a graduated table of 1 ; 5 being first-class wellness and 1 being really hapless wellness ; it does non connote that the person is 5 times as healthier than the 1 who ranks his wellness as really hapless. The chief determination from this survey is that income, in the signifier of an old age pension, improves the wellness position of all family members, in families that pool income ( Case, 2001 ) . The policy deduction of this consequence is that there is a true consequence of pension income on kid wellness. Hence, authoritiess should see hard currency transportations as one means of bettering child wellness. The strength of this paper is evident in the type of study it uses because it interviewed persons individually in order pull out private information to which other family members do non hold entree. Another strength is that the study is designed by dependable governments which make the study reliable. Besides, the study took into history assorted races such as inkinesss, Whites and coloured and controlled for assorted confusing variables such as sex, race, age and figure of pensionaries that could make prejudices in the consequences. Furthermore, for the intent of comparing, the writer presented ordered orbits for inkinesss, Whites and coloured in the U.S, utilizing informations from the National Health Interview Survey ( NHIS ) from 1986-1995. Hence, the findings from this survey can be applicable to U.S.A. In add-on, strengths were found in the clip period for the Langeburg study because it was run 9 old ages from the clip the apartheid ended in 1990. This implies that most of the pensionaries ne'er expected such a good pension. Therefore, this represents a genuinely â€Å" exogenic † addition in old age income like winning a lottery and shows a causal consequence of an addition in income. Similar to the article above, strengths were besides found within the internal cogency of the survey because the survey entails an first-class natural experiment ; hence there were no prejudices in the manner people behaved. However, failings are seen in the study used because it samples a little figure of persons ( 1300 persons ) . Second, the information was self-reported, therefore they might hold been misreport which makes it hard to corroborate or deny many claims. Failings are besides found in the external cogency of this survey since the consequences from this survey may non be representative of other countries of South Africa and other states in Africa or the wider developing universe because South Africa is an exceeding society. Another major failing of this article is the job of gauging the impact of income on kid wellness due to omitted variables such as rearing accomplishments. Besides, the writer did non do usage of a panel information which helps to reply inquiries about the kineticss of alteration. Section 5: Adda, J. , Gaudekcer, H. , & A ; Banks, J. 2006, December 18. â€Å" The Impact of Income Dazes on Health: Evidence from Cohort Data. † Institute for Fiscal Studies, IFS Working Documents: W07/05, 32, 1-32. This article surveies the consequence of lasting income inventions ( dazes ) on wellness for a prime-aged population with peculiar focal point on the consequence of income dazes on wellness over the life-cycle. Income shocks signify alterations in the income of cohorts to bring out causal effects of income dazes on wellness. The policy relevancy of this article is the extent to which income policies really lead to betterments in wellness position. The cardinal findings in the literature on which this article builds is that those with greater degrees of economic resources have better wellness. The information beginnings used are three different cross-sectional studies that sampled more than half a million persons over a 25 twelvemonth period ( 1978 to 2003 ) and reported elaborate information on person ‘s wellness ( both subjective and nonsubjective steps ) , wellness behaviors, income, outgo and socio-economic factors ( Adda et al, 2005 ) . The first study is The Family Expenditure Survey ( FES ) which contains elaborate information on family and ingestion. This information covers the period from 1978 to 2003 and the sample size consists of 148,517 persons. The 2nd study is The General Household Survey ( GHS ) which contain inquiries on wellness steps and hazard behaviors ; it covers the period from 1971 to 2003. The 3rd study, The Health Survey for England ( HSE ) unlike the old two, sampled a little figure of people and covers a little clip period from 1991 to 2003 ( Jerome et al, 2005 ) . The writer estimates the consequence of income dazes on wellness over the life-cycle by stipulating an single dynamic theoretical account of both income and wellness which allows for the decomposition of wellness and income dazes into transitory and lasting 1s. The writer allows for a non-linear relationship between income and wellness at single degree. The writer theoretical accounts income and wellness as stochastic procedures that evolve over the lifecycle and uses collection method to place lasting dazes to income by utilizing man-made cohort informations followed for up to 25 old ages ( Adda et al, 2005 ) . An advantage of utilizing the man-made cohort informations is that it helps to work a wealth of informations with elaborate information on both income and many wellness results because it allows the combination of assorted datasets ( Adda et al, 2005 ) . In order to pattern the stochastic procedure for single income, the writer uses the undermentioned equation: Yit = Yi, t-1 + ( 1 – Liter ) uit + vit, where Yit represents income, L denotes the lag-operator and mistake footings are denoted by uit and vit. Likewise, to pattern the stochastic procedure of single wellness, the writer treats wellness as a uni-dimensional stock variable and augments it with an individual-specific attack for coherence grounds. The methods of appraisal used by the writers consisted of several stairss ; the first measure was to regress the wellness and income variables on a suited set of regressors capturing cohort and age effects, the 2nd measure was to utilize the first-differences remainders and the last was to utilize the GMM technique ( Adda et al, 2005 ) . The chief consequence from this survey is that, income dazes has small effects on wellness position, but do affect wellness behaviors ( such as eating wonts ) and mortality ( Adda et al, 2005 ) . The policy deduction of these consequences provides grounds that lasting income dazes lead to poorer wellness behavior and no grounds that it straight affects wellness steps ( such as blood force per unit area ) . Clearly, the strength of this article is found in the information beginning used since it covers the life-cycle – a 25 twelvemonth period from 1978 to 2003 and studies comprehensive information about the persons in survey. Second, strengths are found in the internal cogency of this survey such that the study samples a big figure of persons – more than half a million persons. Third, the studies used are gotten from two states U.S and England which helps for comparing, pertinence and generalisation. Conversely, failing of this article comes from the methods of appraisal because it is really ill-defined and hard to understand. For illustration, the writer does non supply the significance for the GMM technique. Failings are besides seen from the self-reported wellness position which might make prejudice in the consequences because persons might supply incorrect information. Besides, this survey is an experimental survey which involves a strictly descriptive informations ; therefore it does non do any anticipations sing causality. Weaknesses besides root from the absence of a panel information that compares differences amongst persons ‘ overtime and are peculiarly utile in replying inquiries about the kineticss of alteration. The usage of a panel information will beef up the external cogency of this survey. Section 6: Pritchett, L. , & A ; Summers, L.H. , 1996. â€Å" Wealthier is Healthier. † Journal of Human Resources, Vol. 31 no. 4: 841-68. The writers of this article examine the consequence of income on wellness utilizing cross-country, clip series informations on wellness ( infant and child mortality and life anticipation ) and per capita income. The policy relevancy of this article involves increasing a state ‘s per capital income to see its consequence on kid wellness. The cardinal literature on which this article builds is the 1 that has estimated an income-health relationship utilizing cross-national informations. The cardinal findings in the literature on which this article builds is similar to the consequences gotten in this survey but the research workers who conducted these surveies were unable to turn to issues of causality ( Pritchett et al, 1996 ) . The information beginning used is the 1 at five-year intervals over the period from 1960 up to 1985, for a upper limit of five observations per state ( Pritchett et al, 1996 ) . The writer uses the OLS and IV theoretical accounts as the method of appraisal ; the OLS consequences on infant mortality was foremost reported and so the hardiness of the OLS estimates with regard to fluctuations of timing of observation, informations quality and income definition were verified. The IV estimations for infant mortality for a individual specification and sample was besides reported. Similarly, OLS and IV estimations for entire kid ( under 5 ) mortality and life anticipation were accounted for ( Prichett et al, 1996 ) . The writer estimated the five twelvemonth log differences for states with GDP per capita below $ 6000 utilizing observations for the old ages 1960 to 1985. The writer utilised instrumental variables as an appraisal scheme to place the causal consequence of income on wellness. In strumental variables in this context are variables that are non influenced by an unseen variable suspected to be doing both income growing and wellness betterment ( Prichett et al, 1996 ) . The chief decision of this survey is that additions in state ‘s income raises wellness position ( Prichett et al, 1996 ) . The policy deduction of this consequence is that much of the betterment in kid wellness is due to the acceptance of low-priced intercessions that exists for cut downing infant mortality non attributable to income alterations. Hence, these low-priced intercessions should be implemented along with income policies for overall betterment in child wellness. The strengths of this article prevarication in the information beginning since it covers a long clip period from 1960 to 1985 utilizing a five-year interval. Strength comes from the writer ‘s usage of instrumental variables and other health-status indexs such as mortality and life anticipation. Instrumental variables are determiners of income growing but exogenic with regard to wellness. The importance of utilizing mortality as an index of wellness position is that, it is available for a big figure of old ages and states ( Pritchett et al, 1996 ) . Furthermore, it avoids the potentially more terrible contrary causing jobs associated with the relationship between grownup wellness and income growing ( Pritchett et al, 1996 ) . Another strength found was that confusing variables such as instruction and income were controlled for so as to forestall prejudice in appraisal. The failing of this article is that it does non supply information about socio-demographic features of persons and does non stipulate the figure of persons in the survey. In add-on, some of the information beginnings discussed in this article did non come from dependable beginnings.Section 7: Drumhead, Unanswered Questions, and Suggestions for Future ResearchHaving evaluated the findings and decision in these articles, we see that the overall decisions in these articles are that income has a important impact on wellness position. Given that the five articles utilised different appraisal methods every bit good as dissimilar explanatory variables, it is hard to notice on the overall effectivity of the policies involved in these articles. Measuring the articles separately, Case Anne used pension income as an instrument to analyze the relationship between income and wellness position. He found out that pension income improved the wellness position of all persons in the family that pool income. This provided the grounds that there is a true consequence of pension income on kid wellness. Therefore , we can come into a decision that pension policy was effectual in this instance. In deciding the issue with respects to the unreciprocated inquiries, it is indispensable to measure the strengths and failings of the articles. For illustration, the usage of instrumental variables and the control of confusing variables strengthened the internal cogency of the surveies. The skip of of import variables weakened the internal cogency of the survey. For case, in the article, â€Å" Does Money Protect against Health Status † Evidence from South African Pensions, there were omitted variables such as rearing accomplishments which might hold been correlated with wellness and income. Therefore, an unreciprocated inquiry will be, â€Å" what are other possible omitted variables? † A following inquiry will be in respects to external cogency, for illustration can the consequences in these surveies be applicable to Canada every bit good as other states? A subsequent inquiry will be, â€Å" What other policies could be implemented in order to relieve the impact of i ncome on wellness position? To reason, since it is clear from the analysis in each article that the being of a causal nexus between income and wellness is still unsure, an docket for future research will be to use random fluctuations in income and do usage of panel informations theoretical accounts. Another country of future research will be to include omitted variables in future surveies so as to beef up the internal cogency of the survey. A subsequent country of research will be to avoid self-reported data point in the survey so as to avoid misreport from respondents. Surveies should besides affect more of natural experiments since people in these types of surveies are non cognizant that they are being studied. This would beef up the internal cogency of the survey every bit good as prevent prejudice in consequences. In add-on, future researches should do usage of appraisal methods that are easy to understand every bit good as utilize panel data point which helps to reply inquiries about the kineticss of alter ation and utile in foretelling long-run or cumulative effects which are usually hard to analyse in a cross-sectional survey.
