Animal Essays (1984 words) - Meat Industry, Animal Welfare

Animal Suffering When you go out to eat and look at your thick and juicy T-bone steak what do you think about? When you look at that gorgeous mink coat in the department store what is going through your mind? When you here that cigarette smoke causes cancer in lab animals what is the first thing that comes to mind? Chances are that in each of these cases you were not thinking about how the cow suffered while it was being fattened up, ho painful the trap was that caught those mink, or the conditions those lab animals hat to endure to develop that cancer. Most people do not think about these things. However, in this paper, you will be enlightened on the pain and suffering of animals in three different industries and you will also hear from the other side of this issue. First, one of the biggest culprits of animal suffering is the animal food industry. This is an industry in which people have a tendency to block out or ignore the animal mistreatment; this is done by disassociating oneself with the direct harm and ignoring the indirect harm (Harnack 133). A good start under this example in the case of pigs. Normally, pigs are intelligent animals capable of showing affection. They have very good senses of smell, which is why pigs have been used as hunting animals (Coats 31). This normal behavior is disrupted however in the food industry. Pigs are taken to slaughter at about twenty-four weeks of age when they are approximately 220 pounds (Coats 32). Pigs are usually mass-caged into groups that consist of other pigs of the same sex and age. This can cause excessive aggressiveness in the animals due to the stifling of the natural social orders, which are accomplished though mixing (Coats 33). Due to inactivity in cages, pigs become "bored" and do things such as gnaw on the bars of the cage or on the body parts of other pigs. Factory owners attempt to remedy this by doing things such as cutting off a piglet's tail shortly after being born (Coats 33). There is also gender specific cruelty. To reduce aggressiveness, male pigs are castrated. Most of the time, this is done without anesthetic. This is a practice seen in other divisions of the farm industry as well (Coats 33). "A factory breeding sow [pig] averages two and a half litters a year and ten litters in a life time. With ten or eleven piglets per litter, she brings 100-110 piglets into the systems during the first four to five years of her life" (Coats 34). The pig factory owners try to get the greatest amount of piglets in the least amount of time. They do this by trying to find the optimum amount of time to leave a piglet with his mother. The later a piglet is weaned away from his mother, the better chance it will live, however this is time that the mother is not pregnant (Coats 34). Pigs confined in cages in factories have a high rate of disease and physical problems that range from respiratory diseases to lame and broken legs (Coats 45). Next, we have cows. Cows have the "opportunity" to go into three different division of the farming industry: dairy cow, veal calf, or beef cow (Coats 7). Firstly, concerning milk cows, the only time that a female cow produces milk is after she has had a calf, and she only produces for as long as the calf suckles (Coats 50). To keep the cows producing milk, they must be impregnated about once a year and give birth (Coats 56). While a calf is still getting milk from its mother, it drinks small quantities about twenty times a day. The cow replenishes itself as needed. In the dairy farm, a cow is "sucked dry" approximately two to three times per day. This forces a cow to be over loaded and weighed down with milk (Coats 50-51). When an exceptional cow is found, she is put aside for breeding. She is given drugs to induce the production of more eggs. These eggs are fertilized with the sperm of "super-bulls" and the embryos are implanted into different cows. This can cause problems if the calf implanted is larger than the mother can bear (Coats 56-57). Secondly, under cows, we have the veal calf. The main resource for veal calves is the calves of dairy cows (Coats 61). According to David Coats, "The concept is simple yet very cruel; from birth, calves are

Ethics of Bottled Water

Ethics of Bottled Water Introduction The manufacture of bottled water began in Europe in the 1970s. This was because tap water was considered unsafe after the industrial revolution. Its market grew rapidly in the1990s when it became a business venture.Advertising We will write a custom term paper sample on Ethics of Bottled Water specifically for you for only $16.05 $11/page Learn More Marketers and advertisers promoted it as a symbol of status. Celebrities were seen drinking bottled water during their interviews, concerts, and shows, hence, this further increased its prestige. Moreover, it was used to demonstrate a healthy image. Marketers targeted young people in the gym and sports facilities. Over the years, its consumption has increased making it a household good. It is the fastest selling non- alcoholic beverage according to Doria ( 2006). Different brands have emerged, making its market segment extremely competitive. Similarly, many multinational companies have been created. They extract water from aquifers and springs, package and sell at a competitive price. Some of the leading bottlers include; Fiji Water, Evian, Aquafina, and Dasani among others. The ethics of supplying bottled water have been debated for a long time. Perhaps, this is because water, as a public good has been converted into a private good. Various researchers on the topic, have outlined critical issues facing bottled water. Brei and Bohm (2011) indicate that some communities in the world have no reliable water supply, thus, the consumption of bottled water seems socially unjust. Besides, processing and transporting of bottled water consumes a lot of energy.Advertising Looking for term paper on ethics? Let's see if we can help you!

Also, crude Oil, a health hazard, is used to make the containers used to transport water, hence; this poses a serious health and environmental issue. In addition, the composition of bottled water has been questioned. According to Brooks et al (2009), a brand of the coca-cola company was accused of containing high levels of bromate (2009). Consequently, it was labeled ‘cancer water’ because bromate enhances cancer. Disposing bottled water containers in a sound way poses a challenge. Consumers dispose water containers carelessly. These containers can be found in social areas and other open spaces. On the other hand, bottled water is convenient. It is easy to carry around, and it can be found in almost all the stores. This paper focuses on the ethics of bottled water by evaluating its effect on water supply and the environment. Furthermore, it examines the ethical effects transforming a public-sector good into a private-sector good. Public good Water is a public good. This means that it is nonexclusive. The rivers and lakes are national goods while the municipal water systems are communal-public goods. Private supply of such a good is costly because beneficiaries will have to be excluded from enjoying the good. Excluding individuals requires bottlers to process and package it.Advertising We will write a custom term paper sample on Ethics of Bottled Water specifically for you for only $16.05 $11/page Learn More This process consumes energy in a world where energy is limited. The bottled water culture has caused increased spending on a commodity that should be provided freely. In the past, utility companies and public agencies controlled the market, presently; multinational corporations have privatized water systems for their own benefits. Bottlers are purchasing rights to groundwater distribution channels (Brei and Bohm, 2011). This action makes water, a basic human right into a private commodity. The public is denied access to clean and safe water. Bottled water shifts the attention of the public from the public systems and municipal treatment pla nts. As a result, the community fails to provide accountability on water issues. In the end, the municipality will have little incentive to improve water infrastructure because they lack support. Consequently, the problem of bottled water will increase because consumers will lose faith in tap water. This problem is made worse when the majority can afford bottled water. In the event that the quality of municipal water decreases, the minority are prone suffer. Cost of Bottled Water Bottled water is expensive to produce. Gleick and Cooley in their article â€Å"Energy Implications of Bottled Water† claim that it requires 2000 times more energy compared to tap water (2009).Advertising Looking for term paper on ethics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Water bottles are made from a thermoplastic polymer. The material used contains energy, and more energy is used to transform the material into bottles (Gleick and Cooley, 2009). Bottled water requires energy to run the machinery and equipments used for processing and packaging. The primary source of bottled water is municipal water or groundwater. Municipal water can either be bottled without further treatment or bottled after further treatment. Further purification of water requires energy (Gleick and Cooley, 2009). Besides this, energy is required to transport bottled water and refrigerate it before it is sold. This further depletes the limited fossil fuel available globally. For example, Fiji water supplies millions of bottled water to the United States daily. The cost of transport is reflected in the final cost. According to Gleick and Cooley, production of water bottles consumes over 50 million barrels of oil in a year. This oil is enough to supply the needs of the United State s for almost three days. Apart from the cost of energy, bottled water hinders development, thereby costing the community. In some regions, individuals work in water companies to produce water for other countries. However, in their homes, the water they consume is not clean. For example, Fiji supplies over a million bottles of water to the United States daily. Nevertheless, most people in the Fiji struggle to obtain clean water. Environmental Effects of Bottled Water Bottled water disposal has presented a crucial waste management problem. Thousands of plastic bottles are carelessly disposed by consumers every day. Out of these, a small percentage is recycled while the rest is disposed in landfills. To make it worse, some of these containers end up in rivers, lakes and other water bodies. Water bottles do not attract the deposit for recycling offered to soda and beer bottles (Brooks et al., 2009). Disposal of plastic bottles pollutes the soil because the chemical composition of plasti c takes years to decompose. If these bottles are burnt, the chemicals released into the air cause pollution. Similarly, when exposed to high temperatures, these containers release harmful substances. When these chemicals are released into the ecosystem, they cause cardiovascular and gastrointestinal ailments to human beings. Consequently, the chemicals released such as dioxin, contribute to acid rain and global warming. Convenience of Bottled Water Although bottled water poses waste management challenges, it is exceptionally convenient. Distributors view that transporting small bottles are convenient, as opposed to bulk containers. In addition, consumers consider it pure compared to tap water. Tap water may be pure at the water plants, but after passing through distribution pipes, the water becomes contaminated. Besides, tap water is associated with bad taste and odor (Doria, 2006). Doria in his article â€Å"Bottled Water Versus Tap Water: Understanding Consumers’ Preferenc es† asserts that consumers prefer bottled water because of its ‘organoleptic’ characteristics (2006). Consumers also consider the fact that if contamination is discovered; the bottler will act more efficiently than the government in neutralizing the problem. Purity and contamination are not the only convenient facts about bottled water. Doria (2006) notes bottled water saves time and energy. Buying water indicates that consumers have less time to fill their own containers (Brei and Bohm, 2011). The availability of bottled water allows consumers to buy water when they need it. It saves them from carrying a container of water everywhere. Moreover, the consumer can dispose the container after consuming the water. Solutions to Bottled Water Problems The cost of bottled water, by a larger degree outweighs its benefits making it a problem. Bottlers and producers of bottled water do not consider the cost of disposing the containers. This means that the taxpayer has to co ver these costs (Brei and Bohm, 2011). One solution to this problem is to order the bottlers to pay for the cost of disposal. Given that pollution taxes will reflect on the consumer price, the price of bottled water will increase while the demand decrease. With less people buying bottled water, the environmental effect will reduce. Secondly, water containers can be washed and re-used again to ease pollution. Thirdly, bottlers can use local facilities for production instead of transporting water from far- away locations. This will reduce the price of bottled water and the amount of energy used for transportation. As a public good, government and local institutions can deal with bottled water by defining limits between what is viewed as public or private. This means that companies will no longer have to extract water from springs or aquifers and sell. In addition, the government should set sanctions for companies which violate these rules (Brei and Bohm, 2011). For this to work, the g overnment needs the cooperation and participation of the public. However, rather than trying to reduce the problem of bottled water, public water should be made clean. The government and policy makers should replace old pipes and modernize public water plants. This will ensure consumers drink clean, affordable water. If tap water is safe, then bottled water will only be a luxury. Conclusion Bottled water may be cheap and convenient, but in the long run, it has a high environmental cost. Its consumption of energy is 2000 times that of tap water. Moreover, its disposal causes water, soil, and water pollution. Plastic containers end up in landfills where the bottles take up space, since the material used for their production is not biodegradable. However, despite its energy and environmental implications, bottled water is seen as socially unethical. This is because bottled water turns a public good into a private commodity. As a social good, water should be available to everyone instea d of being sold at high prices. The other reason that makes bottled water unethical is when it is sold to communities who lack a dependable source of water. For example, some communities in Africa face famine yet water are sold in other regions of the same country. In my opinion, it is wrong to sell water while people are drying. It is also unethical to sell water because it is a human right and not a good sold to individuals who have the money to buy it. The assumption that bottled water is purer is not necessarily true. According to Doria (2006), this assumption should not be generalized because it depends on salient cases. For this reason, tap water is socially, environmentally and morally ethical as opposed to bottled water. References List Brei, V., Bohm, S. (2011).

Money, Banking, and Financial Markets Essay Example | Topics and Well Written Essays - 2250 words

Money, Banking, and Financial Markets - Essay Example In this article, I will analyze the current money neutrality and the creation of reserve without money creation as per the central banking systems. Money neutrality Numerous economics students have been taught the theory of money neutrality and its effect on how people consider the issue of monetary policy. The implications of money neutrality may be summarized as follows: in the long run, the growth of money ought to be neutral in its impact on the production growth rate and ought to affect the inflation rate. The earliest canonical works on the neutrality of money stated the superiority of monetary policy regulations that enabled the participants in the market to envisage the future money supplies. There were no debates in these abstract models for the necessity of an institution like a central bank that may be used to take the actions to apply a policy based on rules (Cecchetti 42). There were also no differences identified between the central bank’s liabilities and money. Theoretically, the gap between the inflation variables and the central bank variables (M1 and M2) are under the transmission mechanism, which is a monetary theory. The Federal Reserve utilizes the open market to withdraw or inject commercial bank reserves. The banks then create money through money multiplier. In a nutshell, banks react to the injection of extra reserves by developing loans that are financed with monetary liabilities like savings deposits and checking (Cecchetti 104). The money multiplier calculates the final adjustment in the supply of money that would be caused by a certain change in the monetary base. Irrespective of the money multiplier value, as long as it is stable, a certain percentage increase in the monetary base would cause a similar percentage increase in money. Therefore, the theory of money multiplier is a brief means of tying a policy rule under the central bank control with inflation and money. Creation of reserve without money The application of the c oncepts of the money multiplier and money neutrality have made a number of Federal Reserve observers argue that the present financial crisis has been caused by the possible result of inflation. For instance, the Financial Times, Martin Feldstein argued that when the economy starts to recuperate, the Federal Reserve will have to lessen the stock money and prevent the high volume of excess reserves in the banks from creating credit and money explosion. The negative money multiplier may be explained by liquidity creation. For instance, from 1981 to 2006, the average credit market assets that the US financial institutions hold have increased by $ 32.3 trillion. Commercial bank reserves that have been held as deposits by the Federal Reserve had reduced by $ 6.5 billion within the same period (Cecchetti 56). In 2006, the total commercial bank reserves in the Federal Reserve were only $18.7 billion. This amount was less than the equivalent amount that was held in banks, in 1951. It is quit e clear that not only have the financial institutions depended on a rise in reserves held at the Federal Reserve to increase credit they have also increased credit by 744 percent as the reserves diminished. Therefore, the subsidiary money multiplier of the augmented bank reserves has been either irrelevant or highly negative. The following figure indicates the

Stop the Massacre Essay Example | Topics and Well Written Essays - 1000 words - 1

Stop the Massacre - Essay Example Palestinians only get to hear of the data regarding their fellow citizens who have passed due to the conflict. However, the reporting is also compromised by media houses that are rooting for a western perspective, which has labeled Palestinians as terrorists yet the majority of Gaza residents are peace-loving citizens and have no arms that threaten Israel’s peace and tranquillity. The Israel army claims that it is undertaking surgical strikes aimed at only killing Hamas fighters (Yaakov 1). However, the grim reality on the ground paints a different picture. Most of the dead are innocent civilians who include children, women and the elderly. The support of the western nations for the conflict points at the eroded moral values of the strongest nations, which ought to stand for the enforcement of human rights. The above story paints a bleak future for Gaza’s residents who have become used to the torrential blasts of Israel mortar. This is a story about the contrast in the lives of Israelis and Palestinians. On the onset of the operation dubbed protective edge, Israelis, in amusement, watched from cinemas and cliffs facing Gaza as their army bombarded Gaza from the air leading to the death of innocent people (Yaakov 1). The Israelis, whom the army claims to be protecting, were celebrating as it pounded and destroyed the lives of Palestinians. This was in contrast to the picture painted by Israel’s media, which claimed that its citizens live under the constant threats of rockets. The war against Gaza was based on a false premise publicized by the Western-backed media so that world can turn a blind eye on the atrocities that are occurring during the military incursion into Gaza. The result of this war is the creation of a modern-day concentration camp and the death of even the unborn babies in the wombs of Palestine’s women. Palestinians cannot leave Gaza since they will be exposed to attacks.  

The British Way of Town-making Essay Example | Topics and Well Written Essays - 2500 words

The British Way of Town-making - Essay Example The elements which have influenced Egyptian, Chinese and Islamic architecture will be explored. The influence. The elements which compose places will be explored with regards to urban design. The influence of philanthropic organizations on built constructions. The philanthropic organization which will be discussed is the Prince of Wales Foundation. Introduction To each individual, a town represents a variety of concepts. It may be the place of residence or occupational endeavors, a town may also represent a public policy structure. These concepts are implicit, especially today when many residents of the United Kingdom reside in a municipality of some classification. A town may be perceived as a collection of edifices surrounded by a park which form a silhouette with the sky. A town may also be perceived as a political structure which is composed of constables and a cul de sac. What are the characteristics of a village? If an area is established as a town, what are the factors that in fluence its development and how long may the locality be designated a town? This becomes a subject of deeper inquiry. The responses have been clarified by archaeologists who discuss the attributes. (De La Bedoyer 1992). The concept of town in the society which has been demonstrated from the legacies of the Graeco- Roman civilization continue to exist today. In Britain, there is a pronounced distinction from the oriental, central and southern regions of the landscape. There has been a geographical dividing line which is characterized as â€Å"Fosse Way†. The manner in which a town develops is equated with the environment in which it inhabits. Greece has been administered by the city- state government in where cities administered their suburbs. The city and the land which composed it became the elements of a constitution system. The same phenomenon occurred in the formation of Rome. Rome became the geographical capitol of Italy. The fact that the location of Rome enabled the fo rmation of a military system. The location of Rome also enabled the sense of citizenship and community which was expressed in the Senatus Populus Romanus which is translated into the Senate and People of Rome. Rome was acknowledged as â€Å"the City† (De La Bedoyer 1992). Discussion The construction of municipalities is one of the most recognized accomplishments of modern society. Cities have always been demonstrative of the conditions of the society in which they partake. This demonstration is manifested by the number of decisions which must be made by its inhabitants on a daily basis. In some situations, these decisions have become integrated to synthesize the perspective of clarity and form which is worthy of what has been conceived. It is the premise of concept which enables the additional comprehension of the implications of these choices. These concepts may be applied to the formation of cities in the present day. This perspective will explore the motivations of these c hoices as they have transpired in the history. The external factors which have caused the formation of cities will also be examined. The changing nature with which cities have been conceived and their synthesis will be explored. The aspiration is to dissipate the concept which has been traditionally perceived, that the cities are a unique phenomenon which occur outside of the scope of consciousness of its members. The members of these cities

Issues with Going Professional in Athletics Career

Issues with Going Professional in Athletics Career Do you think that high school athletes should be able to go professional right after they are done with their high school career? This question is a big argument between many people through out the sports world. This is a big debate because nowadays athletes are becoming bigger, stronger, and faster right out of high school. This is happening because athletes are some of the highest paid people in the world. People in the world are actually breeding for their kids to be a sort of super athlete. Many kids are starting to be trained early in age for sports and to be able to make it further in the sports world. There are some people who believe if high school athletes are physically ready for professionals in a sport that they should be able to go right into it. On the other side of this argument many people believe that high school athletes need to get there education and should go to college where they can play sports and then be drafted to a professional league after their college career is done. In many peoples minds that if an athlete is that ready for professional sports that the athletes should have no problem in collegiate athletics and should standout. Many people believe that the athletes college career will only give them more experience and will help them be better once they are able to make it to the draft and plus they are also getting their education just in case something does happen and they do not make it in the professionals. Many athletes do not make it in professional athletics and by making athletes go to college they can rely on their career and will still be well off in the world. For example, the NFL will not let you enter the draft until you have completed three years in college or in college athletics. This is a ru le to make sure that athletes go to college but after three years many athletes enter the draft and do not finish their career. This is a huge problem because the athlete will not have their career to fall back on. There are only a couple rules athletes must follow for the NBA draft. The first rule is that they must have been in college for one year in order to be entered into the draft. This is because they want athletes to at least try the college experience and to at least be able to make it to college as well. Another rule for the NBA draft is that the athlete must be nineteen years of age and one year removed from high school. These rules were made in the year 2006 and have been enforced ever since. These rules are a very good idea because it makes athletes go to college, which is a good thing. This can also be a bad thing because some athletes can not make it to college and that is a problem for some athletes. The age requirement is a good idea I think because at eighteen years old I dont know if you are ready to play with people like Shaq or someone like that. This rule can work both ways though because there has been many athletes go straight to the draft at eighteen and did very well f or them. A former player says, â€Å"The special ones who can go pro should be allowed to do it.† (Beck H. (2005, June 28)). A key example for this is LeBron James and Dwight Howard! There are amazing athletes and were drafted straight out of high school and were actually first round picks! There have been many players like this such as Kevin Garnett, Tracy McGrady, and Kobe Bryant. In some ways many people think that the age requirement is a good idea because it gives you an extra year for your body to grow or even your mind to grow. This helps athletes to be ready to be a professional and it lets them train and get even better than they already are. Many basketball coaches believe that the draft rules are very good and could change the age requirement to twenty if wanted. They believe that making the age requirement later will just encourage young athletes to go to college even more and then they might realize the importance of a college degree and what they can do with it after their basketball career is over. Many coaches believe that a lot of young athletes are not ready to compete at that high of a level many are not use to traveling that much or even being away from their family and friends that much. â€Å"If you can go to war and die for your country, or go to prison for the rest of your life at 17, then you should also be eligible to go pro at 17.†(Freeman, M. (2004)) A lot of athletes will still be maturing mentally and physically if able to be drafted straight from high school. A lot of younger athletes still do not take responsibility for themselves and their actions. With great privileges, comes great responsi bilities and many people think that high school athletes are not ready for these yet! The NFL has different rules to their draft than other professional organizations. In the NFL draft you must have completed three years in college. There is really no age limit in the NFL draft because you can enter it when you are a senior, junior or even a redshirt sophomore. The only requirement is the three years in college. There have been some athletes who have made it to the NFL straight from high school but this took place a very long time ago because the NFL has had tight rules on these types of things for quite a while. In the NHL draft which is the draft for professional hockey has slim to none rules on entering the draft. They are one of the only sports you can be drafted straight to a professional out of high school. There have been quite a few people who have done it and a major athlete who has done great things is Sid â€Å"The Kid† Crosby. He was drafted straight out of high school and was a huge impact on the NHL he is an amazing athlete and takes on all the veterans of the sport. It is said his name is going to be more known than Wayne Gretzgys. He is breaking records and making new ones as he is a magnificent scorer. The reason that hockey does not have a so called age limit is because there are young people that are better than the older people and once your good you are usually good for a long time. Then there is the MLB draft for Major League Baseball. In the MLB you can be drafted right out of high school if you are good enough. Usually if drafted straight out of high school the franchise will put you on their minor league team to test your ability and if you do well they will move you up to the majors. You can be drafted at any time as long as you are not enrolled in some sort of schooling at the time. There are a lot of high school athletes drafted to the MLB especially pitchers because they are the most needed seeming their arms do not last very long. The most high school athletes that enter the draft are from California. This happens because California is a huge state and has very good baseball programs. Immigration is a huge topic among sports these days. For high school athletes going professional immigration is a huge deal. In America we have some of the highest paying sports and the best sports in the world. Many Immigrants know this and are come to America just for sports. For instance, Sammy Sosa is from the Dominican Republic and is an amazing baseball player. His parents and he had him come to America to be able to play baseball professionally and to make money off of a career he loved. In the Dominican Republic there is not as much money there and Sammy could not afford just to play baseball, he had to work and help his family make it in tough times. There are many families bringing their kids to America if they are good at sports because they have a better shot here of making it big and doing something they love while making money. There are Immigrants all over in our high school athletes and they are very good. Their families have made sacrifices for them to be here to play the game they love in hope that they will make it professional. Baseball is a huge sport for this and so is football and basketball also. Immigration makes it so that people can make it here in sports and help take care of their families back home and there are many immigrants being drafted to the professional leagues. Some examples of Immigrants who have made it big here in sports are: Yao Ming, Paul Gasol, Peja Stolakivich, and many more. So as you can see, Immigration ties right into this topic and actually affects it a lot more than most people think. Another major role in this topic is what kind of high school you have attended. This is a big deal because there are basically two types of schools. There are public schools and private schools. As we all know most public schools are very poor funded and usually do not have a lot of money to spare. In private schools they usually have tons of money and could spare some. This is a huge factor for athletes; athletes who attend a private school have more opportunities and privileges than athletes at public schools. For example, private schools usually have very nice facilities and equipment and do not charge very much for athletes to play the game. At a public school the prices are a lot and there are not nice facilities and not very much money in the program. At private schools there are just coaches. They teach at the school also but are very intelligent in there sport. At public schools they take volunteers or pay a teacher very little to do it that has really no experience and not v ery well suited for the job. The private schools usually make better athletes because they can spend time, money, and the right training to make them good. In public schools this is hard and the athletes are kind of at a disadvantage. This affects them making to the Professionals and could make them not even be able to play in college. There are many great athletes out there but some have better situations and will make it farther because of that. This is how public schools affect high school athletes. All in all in my opinion I believe that athletes should be allowed to be drafted straight out of high school but I think there should be specific leagues just for rookies or high school athletes. I believe in like football there should be a league like the MLB. They will have some minor league teams and have all their young athletes play in that. Then if an athlete does very well in this league you can bring him up or send him back down whenever need be. I think this will help a lot on this issue. Dont get me wrong I believe athletes should be student athletes but some people are just not cut out for school. It should be the persons choice and they get to decide. The smart athletes that care about their future will still go to college and get a degree or they will do it online or something like that. Athletes will realize that they need a backup plan because their bodies are not going to last forever. So in my opinion I believe they should be able to go professional.

I Have a Dream by Martin Luther King Essay

â€Å"I have a dream† was a speech delivered on August 28, 1963 by Martin Luther King in Lincoln Memorial Washington D. C. Martin Luther King’s role or position in his speech is that of an illustrator, or a mediator of peace and equality. He becomes one of those people who have seen the light and wanted to share this light to those other individuals who are still in the dark. He wanted or dreamed of a community wherein racial discrimination is no longer an issue. His ideal community is where everybody is free, no biases for either black or white people nor black or white community. He is in a position as to persuade the people to become more vigilant in watching their freedom and in receiving or wanting equality and justice. He also wanted each and every people to understand that one’s freedom or destiny is bound to the other. Because of this, he wanted everybody to properly exercise civil rights and must not prevent people from using this privilege. Generally, the intended audience of the speech is the black people, and also those who are not such as the white people, but are living with black people or in black communities. However, everybody can read or listen to his speech or statement because of the underlying principles included in his speech and his dreams or ideals can be utilized or preferred as a model for civil rights. â€Å"I have a dream† greatly inspires and effectively infuses its point of view to its audience, transforming dreams into reality and despair into hope; we dream of being free, and we become free because of this dream. Martin Luther King was prompted to write or make the statement or speech because of the continuing slavery that entangles each and every people, especially for the black people or communities. In addition to this, the belief and treatment or actions of the black people against the white people had alarmed the author to write or make this speech to the public. According to Martin Luther King, the slavery of the black people may have been released or abolished because of the signing of the Emancipation Proclamation. However, nowadays or 100 years later, this freedom from slavery is still ambiguous and it does not exist. In addition to this, Martin Luther King believes that there are still a lot of people who are experiencing police brutality and social discrimination. In addition to this, he thinks that the rights and privileges which were given to the people, especially the black people, is not properly implemented or received by the black communities. Martin Luther King takes on the affirmative side or in favor for equality amongst the black people and also the white people. He clearly shows or supports his stand through several examples and emphasis on his words or statements. Martin Luther King claims that every individual should learn to respect and give what is right to their neighbors. He is aware that there are people who are still suffering beyond the hands of law. He reasons this out by giving examples of those who were misunderstood, brutally beaten indiscriminately and provides logic as to why dreaming is an important part in one’s body. Martin Luther King is qualified to be a speaker or author of such paper because of his records and performance not only as a politician but also an individual who greatly cares for justice and freedom. I believe that the assumptions, ideas or claims of Martin Luther King are correct and good, with some deviances especially through the use of audio, video or format or instructions at more school. He was able to provide examples of real life situations where the civil rights of an individual becomes hindered. In addition to this, the audio and video formats are very much entertaining and at the same time, inform the audience of the predicaments of equality or justice in nations or communities. However, there are some claims or dreams which are somehow impossible to attain such as complete equality and freedom from prejudice from all countries or states. Being able to read Martin Luther King’s work, my perspective before to ignore claims and evidences and become settled in what the community gives me, had greatly changed. As such, the degree of my trust towards Martin Luther King did increase due to his great speech which is definitely eye-opening. The author has refutations that include the fulfillment of his dream or conditions in order to achieve a country, state or community. He also refutes the fact that freedom is already complete. The refutations made by Martin Luther King are really effective. In addition to this, he uses great emphasis on his words and greatly touches the sympathy of those who are listening to his speech. He was able to clearly state his dreams, one after the other and manage to state options or categories which would fulfill his dreams. His last statement â€Å"Free at last! Free at last! † gives hopes and restore the faith which people have for change and better living. As an individual who had already received the light from Martin Luther King, my desire for helping other people and providing equality or non-biased reactions had increased. My hopes for a better communication and media for spreading the word of the real scenario on freedom and equality also increased because of the persuasive message or speech delivered by Martin Luther King, Somehow, a part of me already wants to do something in order to help and at least be able to create balance within communities. In addition to this, his metaphor of a ring, representing one goal, and fingers representing the people, is really amazing and in reality lightens my belief. I thought that we are already saved, but the paper of Martin Luther King had taught me well.

Medicine: Portfolio Tasks Essay

Portfolio Task: Module 1 â€Å"Effective study skills are the sole foundation of a sound education†. Study skills or study strategies are approaches applied to learning. They are generally critical to success in school, considered essential for acquiring good grades, and useful for learning throughout one’s life. Study skills are fundamental to academic competence. Effective study skills are associated with positive outcomes across multiple academic content areas and for diverse learners. Study skills improve the competences associated with acquiring recording, organizing, remembering and using information. These skills also contribute to success in both employment and non – academic settings. Studying is often an individual activity and what works for one student with regards to study may not work for someone else. Self regulation is an important aspect of study skills. Having the ability to goal set, work towards deadlines and have persistence in the subject the student is studying will help achieve success. In effect good studiers are good strategy users, they know how to use a variety of goal specific tactics, to execute them in a planned requence and monitor their use. A sufficient amount of time needs to be dedicated to studying to achieve the best outcome. Effective study skills may also help with issues such as confidence and organisational skills which are used in every day activities some students take notes whilst they are reading to help them understand what they are reading. Others students may wish to â€Å"think about† as it helps students to understand and retain information. Many students find that by repeating information they retain it. There is little doubt that no two people study the same way, and it is a near certainty that what works for one person may not work for another. The results of poor study skills are wasted time, frustration, and low or failing grades. It’s your life, your time, and your future. Effective study skills must be practiced in order for you to improve. It is not enough to simply â€Å"think about† studying; you have to actually do it, and in the process use information from what you do t o get better. http://www.wikihow.com/Improve-Your-Study-Skills http://psychcentral.com/lib/top-10-most-effective-study-habits/000599 http://www.adprima.com/studyout.htm http://www.palgrave.com/skills4study/studyskills/learning/effective.asp http://en.wikipedia.org/wiki/Study_skills Portfolio Task: Module 2 â€Å"Briefly describe the importance of the interaction between the respiratory and cardiovascular systems in maintaining the body s internal balance†. When you breathe in air through your mouth and nose it travels to your lungs. Oxygen from the air is absorbed into your bloodstream through your lungs. Your heart then pumps oxygen-rich (oxygenated) blood through a network of blood vessels (arteries) to tissues including your organs, muscles and nerves, all around your body. When blood reaches the capillaries in your tissues it releases oxygen, which cells use to function. Cells release waste products, such as carbon dioxide and water, which your blood absorbs and carries away. The used (deoxygenated) blood then travels through your veins and back towards your heart. Your heart pumps the deoxygenated blood back to your lungs, where it absorbs fresh oxygen, releases the carbon dioxide and the cycle starts again. The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhal e oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. Respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube that enters the chest cavity. In the chest cavity, the trachea splits into two smaller tubes called the bronchi. Each bronchus then divides again forming the bronchial tubes. The bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to tiny sacs called alveoli. The average adult’s lungs contain about 600 million of these spongy, air-filled sacs that are surrounded by capillaries. The inhaled oxygen passes into the alveoli and  then diffuses through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. T he carbon dioxide follows the same path out of the lungs when you exhale. The diaphragm’s job is to help pump the carbon dioxide out of the lungs and pull the oxygen into the lungs. The diaphragm is a sheet of muscles that lies across the bottom of the chest cavity. As the diaphragm contracts and relaxes, breathing takes place. When the diaphragm contracts, oxygen is pulled into the lungs. When the diaphragm relaxes, carbon dioxide is pumped out of the lungs. The cardiovascular system is part of the larger circulatory system, which circulates fluids throughout the body. The circulatory system includes both the cardiovascular system and the lymphatic system. The cardiovascular system moves blood throughout the body, and the lymphatic system moves lymph, which is a clear fluid that’s similar to the plasma in blood. Blood contains nutrients from the foods you eat and oxygen from the air you breathe. It also contains hormones and cells that fight infection. The blood also transports waste products to various places that then promptly remove the waste from the body. The parts of the cardiovascular system include the heart, which is the organ that pumps the blo od, and a network of blood vessels: Arteries: The blood vessels that take blood away from the heart Veins: Blood vessels that return blood to the heart Capillaries: Very small vessels that lie between the arteries and veins The portal vein and its tributaries carry blood from parts of the digestive system to the liver before reaching the heart. The heart is a muscular pump with four chambers inside: the right and left atria and the right and left ventricles. Those four chambers allow the heart to pump blood through the following two circulatory pathways: Systemic circulation: Takes oxygen-rich blood to the tissues and organs of the body Pulmonary circulation: Takes oxygen-depleted blood to the lungs and oxygen-rich blood back to the heart again. 1. The left ventricle of the heart receives oxygenated blood from the left atrium. 2. Blood is ejected from the left ventricle into the aorta, a large artery. The ascending aorta sends blood to the upper thorax, upper extremities, neck, and head. The descending aorta sends blood to the lower thorax, the abdomen, the pelvis, and the lower extremities. 3. The blood leaves the ascending and descending parts of the aorta and enters a network  of systemic arteries that run to all places of the body. 4. Blood passes from the smallest arteries (called arterioles) into the capillary beds. In the capillary beds, blood exchanges oxygen, nutrients, and waste products with the tissues. 5. The oxygen-poor blood leaves the capillary beds via small veins (called venules) and drains into a network of systemic veins that eventually lead to the venae cavae (either of the two large veins leading into the heart). The superior vena cava receives blood from the upper thorax, head, neck, and upper extremities. The inferior vena cava receives blood from the lower thorax, the abdomen, the pelvis, and the lower extremities. 6. The venae cavae empty the oxygen-poor blood into the right atrium of the heart. After systemic circulation, the blood in the right atrium is depleted of oxygen, so it needs to go to the lungs to exchange carbon dioxide for oxygen. The pathway from the heart to the lungs and back to the heart is called pulmonary circulation, and it takes the following path: 1. The right ventricle receives the oxygen-depleted blood from the right atrium. 2. The blood leaves the right ventricle and enters the pulmonary trunk, which splits into two pulmonary arteries. 3. The pulmonary arteries lead to the lungs, where exchange of gases takes place. Carbon dioxide is removed from the blood, and oxygen enters the blood. 4. Blood leaves the lungs via the pulmonary veins.  The pulmonary veins carry freshly oxygenated blood to the heart while the systemic veins carry oxygen-poor blood to the heart. 5. The oxygenated blood enters the left atrium of the heart. The blood in the left atrium moves into the left ventricle and enters the systemic circulation. http://www.fi.edu/learn/heart/systems/respiration.html http://www.mayoclinic.com/health/circulatory-system/MM00636 http://www.dummies.com/how-to/content/what-is-the-cardiovascular-system.html Portfolio Task: Module 3 â€Å"When you ask a patient to plantar flex a foot, what changes occur within the muscles involved?† Plantar flexion is the movement which increases the approximate 90 degree angle between the front part of the foot and the skin, as when depressing an automobile pedal or standing on the tip toes. The movement in the opposite  direction is dorsifexion, where the dorsal part (top) of the foot is moved in a manner towards the tibia. It ocurs at the ankle. The range of motion for planter flexion is usually indicated in the lterature as 30 to 40 degree, but sometimes also 50 degree. The nerves are primarily from the sacral spinal cord roots S1 and S2. Compression of S1 roots may result in weakness in plantar flexion. These nerves run from the lower back to the bottom of the foot. Plantar flexion is the movement of the foot away from the body by bending the ankle. The joints in the ankle are highly involved in plantar flexion.  Ankle movement is made possible by the meeting of three bones: tibia (shinbone or leg), fibula (the small bone in leg) and the talus (a large bone in foot). The end of tibiaconstitutes the inner postion of the ankle, wheareas the outer portoon of the ankle is formed by fibula. The ony bulges on either side of toe ankle are called malleoli which aid is stability of the ankle, joints while standing or walking. Primary muscles for plantar flexion are: Posterior compartment of leg Superficial Gastrocnemius Soleus Plantaris (only weak participation) Deep Flexor hallucis longus Flexor digitorum longus Tibialis posterior Lateral compartment of leg (only weak participation) Fibularis longus Fibularis brevis http://en.wikipedia.org/wiki/Plantarflexion#Flexion_and_extension_of_the_foot Portfolio Task: Module 4 â€Å"A patient comes in with a hot inflamed toe, how does the circulatory system contribute to this process?† When inflammation occurs in the toes it can be caused by a number of conditions, such as gout, rheumatoid arthritis, bunions, bursitis, or ingrown toenails. Toe inflammation is typically a protective measure that the body takes in reaction to injury or the presence of bacteria. This is generally a normal occurrence and it is a part of the natural way that the body heals. It may also be incorrectly triggered by certain conditions or diseases. Gout, which is a type of arthritic condition, is one of the more common causes of toeinflammation. Symptoms of gout often affect the big toe, in which case it may be referred to as podagra. The inflammation is a result of excess uric acid building up in the toe joint. Inflammation that is caused by gout is often seen in people who are overweight, diabetic, havekidney disease, or that are taking certain medications. Toe inflammation may also be caused by the autoimmune disease known as rheumatoid arthritis. For people with this condition, their body’s immune system attacks tissue that is healthy as opposed to responding to injury or bacteria. When this occurs at the toe joints, the result is inflammation. Eventually this will cause other toe problems that can lead to changes that affect a person’s ability to walk and wear most types of shoes. Inflammation is at the root of the most serious complications that occur after infection and injury. But while the course of molecular events leading to microbial infection of the inflammatory condition called sepsis is fairly well understood, is much less clear how and why physical injury can result in an inflammatory response similar dangerous. The process of acute inflammation is initiated by cells already present in all tissues, mainly resident macrophages, dendritic cells, histiocytes, Kupffer cells and mast cells. At the onset of infection, burns or other injury, these cells are activated and release inflammatory mediators responsible for clinical signs of inflammation. Vasodilation and increased blood flow resulting causes redness (rubor) and heat gain (heat), increased permeability of blood vessels produce an exudation (output) of plasma proteins and fluid in the tissues (edema), which manifests as a swelling (tumor). Some of the released mediators such as bradykinin increased pain sensitivity (hyperalgesia, pain). Mediator molecules also alters the blood vessels to allow migration of leukocytes, primarily neutrophils, outside the blood vessels (extravasation) in the tissue.  Neutrophils migrate along a chemotactic gradient created by local cells to reach the site of injury. The loss of function (functio Laesa) is probably the result of a neurological reflex in response to pain. In addition to cell-derived mediators, several acellular biochemical cascade systems is preformed plasma protein s act in parallel to initiate and propagate the inflammatory response. These include the complement system activated by the bacteria, and the systems of coagulation and fibrinolysis activated by necrosis, such as a burn or trauma. Human tissues respond to trauma by a complex series of events that have yet to be fully understood. This trauma may be mechanical, thermal, photo or chemical, or brought about through allergic or autoimmune events. If blood vessels have been injured, damaged platelets will activate the clotting cascade. Damaged tissues will release chemical messengers, which start the inflammatory process. In health, sequential phases of proliferation, maturation and repair of the damaged tissue follow inflammation. Blood cells and platlets, the immune system and nerves, chemical transmitters, and tissue cells such as macrophages are among the tissues and systems involved in inflammation. The molecular and cellular events during inflammation flow into and overlap with one with the other. Initially, neutrophils arrive, followed by macrophages, lymphocites and then fibroblasts, which lay down collagen. Epithelial cells migrate on from wound edges over the newly laid down dermis and healing is complete. Healing by first intention will close over 2 – 5 days; a wound healing by second intention will take longer, the time taken depending on the tissue area that needs to be filled in and covered. The predominance and sequence of mediator release will allow different types of inflammatory response to occur. The classic and clinical features of inflammation are redness, heat, swelling and pain; loss of function is sometimes included in this list. These features are brought about through chemical/inflammatory mediators released from damaged tissues. The main effects of these mediators are on the blood supply, causing vasodilation (redness and heat) and increased blood vessel permeability that allow plasma proteins and immunoglobulins to pass easily into the tissues. Pressure or nerve endings from the  interstitial fluid and the effect of some inflammatory mediators such as substance P and prostaglandins cause pain. Hot inflamed toe it is might be acute or chronic inflammation. Acute inflammation is the initial response of the body to harmful stimuli and is by the increaced movement of plasma and leukocytes from the blood into the injured tissues. A coscade of biochemical events propagates and matures the inflammatory response, involving the local vascular system, the immune system, and various cells within the injured tissue. Chronic inflammation leads to a progressive shift in the type of cells present at the site of inflammation and is characterized by simultaneous destruction and healing of the tissue from the inflammatory process. The respiratory system gets the oxygen it needs and the circulatory system bring the oxygen along with many other products in the blood to the toe. The digestive system helps obtain nutrients for the toe which the blood brings as part of the circulatory system. http://lyceum.algonquincollege.com/lts/AandPResources/videos/2-4_Inflammatory.html http://en.wikipedia.org/wiki/Inflammation http://www.researchomatic.com/essay/Role-Of-Circulatory-System-Inflammatory-Response-56305.aspx http://www.wisegeek.com/what-causes-toe-inflammation.htm Portfolio task: Module 5 â€Å"Discuss the possible presenting symptoms after a hard knock on the leg in the area behind the knee†. A hard knock on the leg to the area behind the knee would certainly be painful. A hard knock to the posterior of the knee could cause many symptoms, depending on the severity of the hit and how long ago it occured. The knee could be swollen or bruiced. Range of motion may be less, or painful. The person may limp or be unable to fear weight. The kneecap could be displaced. The patient will likely complain of moderate to severe pain. Because the knee is not meant to be hyper-extended, the person should go to an ER for X-ray or other imaging. Might be the inability to properly bend or  straighten the knee. Elevate the leg. Alternate between warm moist heat and ice. To help keep the swelling is check, use an ace bandage to supportthe knee. Dont wrap so tightly that it causes indentantion in the skin. Area behind the knee called the popliteal forsa. The nerves most important nerve travelling throught this area is the popliteal nerve that travels to the lower leg and foot and allowing both sensation and motor strength. Injury to the popliteal nerve can cause numbness, tingling, pain, and weakness in the lower leg, ankle and foot. Vascular injury could cause a bleed from either popliteal artery or vein causing a hematoma or blood pool that could causesignificant pain in the area. The main types of injury could include soft tissue, muscle, nerve and artery/vein , ligaments and menesci. A skin and soft tissue injury could include a mild contusion with some redness or brusing. Serathes may occur. If there is a deeper penetration and not appropriate would care, an infection could form causing a skin and soft tissue infection known as a cellulitis. Injury to the muscle could include a tear of the plantaris muscle which travels throught the area of the popliteal fossa. tear of this muscle will not result in too much deformity or motor deficits, but can cause significant pain. The hamstrings insert near the region of the popliteal fossa and could be affected as well causing pain, but unlikely deformity or decreased range of motion. Damage to the ligaments can result in severe pain and disability. The posterior cruciate ligament and the lateral ligaments: the medial collateral ligament and the lateral collateral ligament commonly occur with injury during sports and can cause severe disabling pain and motor dysfunction. These are the main ligaments that allow for smooth motion during knee flexion and extension and a tear which occurs commonly often requires invasive surgical repair. Finally the menisci which are cartilaginous structures found inside the knee joint that allow for smooth movement of the bones in the leg. A meniscal tear can occur in a sports  accident as above with the ligamentous injuries and cause significant pain and decreased range of motion at the knee. This may likewise require surgical evaluation and correction to restore function and eliminate pain. Because the knee is a complicated region and the back of it has many important structures including veins, arteries, nerves, and muscle components, a hard knock to the knee can be extremely debilitating and should be avoided whenever possible. Protection of the knee with appropriate gear is critical when dangerous activities are being attempted. http://www.justanswer.com/medical/5lrvt-500-words-referenced-study-following-discuss-possible.html http://emedicine.medscape.com/article/826792-clinical Portfolio Task: Module 6 Write a proparly referenced essay on the treatment and management of a patient with corns When we walk or stand or body weigh is carried first on the heel and then on the ball of the foot where the skin is thicker to withstand the pressure. When this pressure becomes intense, growth in the form of corns and callus may appear. Corns always occur over a bony prominence, such as a joint. A corn is a small areas of hard skin, roughly round in shape, which press into the skin. They are often found over high-pressure areas of the foot.  There are five different types of corns. The two most common are hard and soft corns. Hard corns the most common and appears as small, concentrated areas of hard skin up to the size of a small pea, usually within a wider area of thickened skin or callous, and can be symptoms of feet or toes not functioning properly. Soft corns develop in a similar way to hard corns. They are whitish and rubbery in texture, and appear between toes, where the skin is moist fromsweat or from inadequate drying. A podiatrist will be able to reduce the bulk of the corns and apply antringents to cut down on sweat  retentionbetween the toes. If a corn is left untreated it will become painful. A corn will not get better on its own unless the pressure that originally caused the corn is removed. If the cause is not removed then the skin will continue to thicken and become more painful. After some time the body may treat the corn as a foreign body and an ulcer or abscess could develop. These can be serious, especially if they become infected. Infection is a very serious complication for individuals with diabetes, poor circulation and peripheral neuropathy. There are many over the counter corn remedies and plasters that are readily available. These, however, do not treat the cause of the corn and can be risky in many individuals such as those with diabetes, poor circulation, frail skin etc. Podiatric management of corns at Podiatry includes: a thorough assessment to determine the cause of the corn implementation of a management / treatment plan Management plans for the treatment of corns commonly consist of: maintenance appointments to keep the corn reduced use of padding to prevent the pressure footwear fitting advice provision of foot orthotics or supports to relieve the pressure under the foot surgical correction of the bony prominence that may be causing the high pressure area Most corns and calleures gradually disappear when the friction or preassure stops, although doctor (cheropodist) may shave the top of a calleus to reduce the thickners. Properly positionece moleskin pads can help relieve pressure on a corn. There are also special corn and callus removal liquids and plasters, usually containing saliaytic acid, but there are not suitable everyone. Oral antibiotics generally clear up infected corns, but pus may have to be drained through a small incision. Moisturising creams may help the skin and remove cracked callures. Apply the misturiing cream to the callus and cover the area for 30-60 minutes with a  plastic bag or a rock. Than gently rub off as much of the callus as you can with a worm towel or soft brush. Using the pumice stone first to rub off a dead skin from a callus after a bath or shower and talk applying moisturaising cream can also be effective. There are also stronger creams containing urea that might be more effective, but do not use these unless recommended by doctor or cheropodist.  May consider surgery to remove a planter callus, but there are no guarantees that the callus will not come back. A conservative approach is best initially. Keep your feet dry and friction – free. Wear proparly fitted shoes and cotton socks, rather then wool or synthetic fibres that might irritate the skin. If a podiatrist thinks your corn or callus i caused by abnormal foot structure your walking motion or hip rotation, orthopaedic shoe inserts or surgery to correct foot deformitie may help correct the problem. When complete reduction of the corn is achievied than 25% or 50% silver nitrate solution may be applied. Example of products that can be used to treat corns and callus include: special rehydratation creams for thickened skin; protective corn plasters; customosed soft padding or foam insoles; small foam wedges that are placed between the toes to help relieve soft corns; special silicone wedges that change the position of your toes or redistribute pressure. http://www.manchesterpodiatry.co.uk/chiropody/corns.html http://emedicine.medscape.com/article/1089807-treatment

Explore the Different Types of Galaxies

Explore the Different Types of Galaxies Thanks to instruments such as the Hubble Space Telescope, astronomers know more about the variety of objects in the universe than previous generations could even dream of understanding.  Even so, most people dont realize just how diverse the universe is. Thats especially true about galaxies. For a long time, astronomers sorted them by their shapes but didnt really have a good idea about why those shapes existed. Now, with modern telescopes and instruments, astronomers have been able to understand why galaxies are the way they are. In fact,  classifying galaxies by their appearance, combined with data about their stars and motions, give astronomers insight into galactic origins and evolution. Galaxy stories stretch back almost to the beginning of the universe.   This Hubble Space Telescope view reveals thousands of galaxies stretching back into time across billions of light-years of space. The image covers a portion of a large galaxy census called the Great Observatories Origins Deep Survey (GOODS). NASA, ESA, the GOODS Team, and M. Giavialisco (University of Massachusetts, Amherst) Spiral Galaxies Spiral galaxies are the most famous of all galaxy types. Typically, they have a flat disk shape and spiral arms winding out away from the core.  They also contain a central bulge, within which a supermassive black hole resides. Some spiral galaxies also have a bar that runs through the center, which is a transfer conduit for gas, dust, and stars. These barred spiral galaxies actually account for most of the spiral galaxies in our universe and astronomers now know that the Milky Way is, itself, a barred spiral type.  Spiral type galaxies are dominated by dark matter, making up nearly 80 percent of their matter by mass. An artists concept of what our galaxy looks like from outside. Note the bar across the center and the two main arms, plus smaller ones. NASA/JPL-Caltech/ESO/R. Hurt Elliptical Galaxies Less than one in seven galaxies in our universe are elliptical galaxies. As the name suggests, these galaxies are either range from having a spherical to egg-like shape.  In some regards they look similar to large star clusters, however, the presence of large amounts of dark matter help distinguish them from their smaller counterparts. A giant elliptical galaxy has a small neighbor with a HUGE black hole at its heart. NASA/ESA/STScI These galaxies contain only small amounts of gas and dust, suggesting that their period of star formation has come to an end, after billions of years of rapid star-birth activity.   This actually gives a clue to their formation as they are believed to arise out of the collision of two or more spiral galaxies. When galaxies collide, the action spurs great bursts of star birth as the commingled gases of the participants are compressed and shocked. This leads to star formation on a grand scale.   Irregular Galaxies Perhaps a quarter of galaxies are irregular galaxies. As one might guess, they seem to lack a distinct shape, unlike spiral or elliptical galaxies. Sometimes astronomers have referred to them as peculiar galaxies, due to their odd shapes. No matter what theyre called, astronomers want to understand why they often look like oddballs when compared to other galaxy types. One possibility is that these galaxies were distorted by a nearby or passing massive galaxy. We see evidence for this in some of the nearby dwarf galaxies that are being stretched by the gravity of our Milky Way  as they are cannibalized by our galaxy. The Large Magellanic Cloud (middle left) and Small Magellanic Cloud (upper center) over Paranal Observatory in Chile. European Southern Observatory In some cases though, it seems that irregular galaxies have been created by mergers of galaxies. Evidence for this lies in the rich fields of hot young stars that were likely created during the interactions. Lenticular Galaxies The lenticular galaxies are, to some extent, misfits. They contain properties of both spiral and elliptical galaxies. For this reason, the story of how they formed is still a work in progress, and many astronomers are actively researching their origins.   Galaxy NGC 5010 a lenticular galaxy which has features of both spirals and ellipticals. NASA/ESA/STScI Special Types of Galaxies There are also some galaxies that contain special properties that help astronomers classify them even further within their more general classifications.   Dwarf Galaxies: These are essentially smaller versions of those galaxies listed above. Dwarf galaxies are difficult to define because there is no well-accepted cut-off for what makes a galaxy regular or dwarf. Some have a flattened shape and are often referred to as dwarf spheroidals. The Milky Way is currently cannibalizing a number of these smaller stellar collections. Astronomers can track the motions of their stars as they swirl into our galaxy, and study their chemical makeup (also known as metallicity).Starburst Galaxies: Some galaxies are in a period of very active star formation. These starburst galaxies are actually normal galaxies that have in some way been disturbed to ignite very rapid star formation. As mentioned above, galaxy collisions and interactions are the likely cause of the starburst knots seen in these objects.Active Galaxies: It is believed that virtually all normal galaxies contain a supermassive black hole at their cores. In some cases, however, this central engine can become active and drive massive amounts of energy away from the galaxy in the form of powerful jets. These Active Galactic Nuclei (or AGN for short) are widely studied, but it is still unclear what causes the black hole to suddenly become active. In some cases, passing clouds of gas and dust may fall into the gravitational well of the black hole. The material gets superheated as it swirls around in the black holes disk, and a jet may form. The activity also gives off x-rays and radio emissions, which can be detected with telescopes here on Earth. The study of galaxy types continues, with astronomers looking back to the earliest epochs of time using Hubble and other telescopes. So far, theyve seen some of the very first galaxies and their stars. These little shreds of light are the beginnings of the galaxies we see today. The data from those observations will help the understanding of galactic formation back at a time when the universe was very, very young.   This simple diagram of galaxy types is often called Hubbles tuning fork. public domain Fast Facts Galaxies exist in a variety of shapes and sizes (called their morphology).Spiral galaxies are very common, as are ellipticals and irregulars. The first galaxies were likely irregulars.Galaxies grow and evolve through collisions and mergers.

Multithreaded Delphi Database Queries With dbGo (ADO)

Multithreaded Delphi Database Queries With dbGo (ADO) By design, a Delphi application runs in one thread. To speed up some parts of the application you might want to decide to add several simultaneous paths of execution in your Delphi application. Multithreading in Database Applications In most scenarios, database applications you create with Delphi are single threaded- a query you run against the database needs to finish (processing of the query results) before you can fetch another set of data. To speed up data processing, for example, fetching data from the database to create reports, you can add an additional thread to fetch and operate on the result (recordset).

Customer Order Scenario In the well-known scenario where a customer places orders containing items, you might need to display all the orders for a particular customer along the total number of items per each order. In a normal single threaded application you would need to run the query to fetch the data then iterate over the recordset to display the data. If you want to run this operation for more than one customer, you need to sequentially run the procedure for each of the selected customers. In a multithreaded scenario you can run the database query for every selected customer in a separate thread- and thus have the code execute several times faster. Multithreading in dbGO (ADO) Lets say you want to display orders for 3 selected customers in a Delphi list box control. type   Ã‚  TCalcThread class(TThread)  Ã‚  private   Ã‚  Ã‚  Ã‚  procedure RefreshCount;  Ã‚  protected   Ã‚  Ã‚  Ã‚  procedure Execute; override;  Ã‚  public   Ã‚  Ã‚  Ã‚  ConnStr : widestring;   Ã‚  Ã‚  Ã‚  SQLString : widestring;   Ã‚  Ã‚  Ã‚  ListBox : TListBox;   Ã‚  Ã‚  Ã‚  Priority: TThreadPriority;   Ã‚  Ã‚  Ã‚  TicksLabel : TLabel;   Ã‚  Ã‚  Ã‚  Ticks : Cardinal;   Ã‚  end; This is the interface part of a custom thread class we are going to use to fetch and operate on all the orders for a selected customer. Every order gets displayed as an item in a list box control (ListBox field). The ConnStr field holds the ADO connection string. The TicksLabel holds a reference to a TLabel control that will be used to display thread executing times in a synchronized procedure. The RunThread procedure creates and runs an instance of the TCalcThread thread class. function TADOThreadedForm.RunThread(SQLString: widestring; LB:TListBox; Priority: TThreadPriority; lbl : TLabel): TCalcThread;var   Ã‚  CalcThread : TCalcThread; begin   Ã‚  CalcThread : TCalcThread.Create(true) ;   Ã‚  CalcThread.FreeOnTerminate : true;   Ã‚  CalcThread.ConnStr : ADOConnection1.ConnectionString;   Ã‚  CalcThread.SQLString : SQLString;   Ã‚  CalcThread.ListBox : LB;   Ã‚  CalcThread.Priority : Priority;   Ã‚  CalcThread.TicksLabel : lbl;   Ã‚  CalcThread.OnTerminate : ThreadTerminated;   Ã‚  CalcThread.Resume;   Ã‚  Result : CalcThread; end; When the 3 customers are selected from the drop down box, we create 3 instances of the CalcThread: var   Ã‚  s, sg: widestring;   Ã‚  c1, c2, c3 : integer; begin   Ã‚  s : SELECT O.SaleDate, MAX(I.ItemNo) AS ItemCount   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   FROM Customer C, Orders O, Items I   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   WHERE C.CustNo O.CustNo AND I.OrderNo O.OrderNo ;   Ã‚  sg : GROUP BY O.SaleDate ;   Ã‚  c1 : Integer(ComboBox1.Items.Objects[ComboBox1.ItemIndex]) ;   Ã‚  c2 : Integer(ComboBox2.Items.Objects[ComboBox2.ItemIndex]) ;   Ã‚  c3 : Integer(ComboBox3.Items.Objects[ComboBox3.ItemIndex]) ;   Ã‚  Caption : ;   Ã‚  ct1 : RunThread(Format(%s AND C.CustNo %d %s,[s, c1, sg]), lbCustomer1, tpTimeCritical, lblCustomer1) ;   Ã‚  ct2 : RunThread(Format(%s AND C.CustNo %d %s,[s, c2, sg]), lbCustomer2, tpNormal,lblCustomer2) ;   Ã‚  ct3 : RunThread(Format(%s AND C.CustNo %d %s,[s, c3, sg]), lbCustomer3, tpLowest, lblCustomer3) ; end; Traps and Tricks With Multithreaded ADO Queries The main code goes in the threads Execute method: procedure TCalcThread.Execute;var   Ã‚  Qry : TADOQuery;   Ã‚  k : integer; begin  Ã‚  inherited;  Ã‚  CoInitialize(nil) ; //CoInitialize was not called   Ã‚  Qry : TADOQuery.Create(nil) ;  Ã‚  try// MUST USE OWN CONNECTION // Qry.Connection : Form1.ADOConnection1;   Ã‚  Ã‚  Ã‚  Qry.ConnectionString : ConnStr;   Ã‚  Ã‚  Ã‚  Qry.CursorLocation : clUseServer;   Ã‚  Ã‚  Ã‚  Qry.LockType : ltReadOnly;   Ã‚  Ã‚  Ã‚  Qry.CursorType : ctOpenForwardOnly;   Ã‚  Ã‚  Ã‚  Qry.SQL.Text : SQLString;   Ã‚  Ã‚  Ã‚  Qry.Open;   Ã‚  Ã‚  Ã‚  while NOT Qry.Eof and NOT Terminated do   Ã‚  Ã‚  Ã‚  begin   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  ListBox.Items.Insert(0, Format(%s - %d, [Qry.Fields[0].asString,Qry.Fields[1].AsInteger])) ;   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  //Canvas Does NOT Allow Drawing if not called through Synchronize   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Synchronize(RefreshCount) ;   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Qry.Next;   Ã‚  Ã‚  Ã‚  end;  Ã‚  finally   Ã‚  Ã‚  Ã‚  Qry.Free;   Ã‚  end;   Ã‚  CoUninitialize() ; end; There are 3 traps you need to know how to solve when creating multithreaded Delphi ADO database applications: CoInitialize and CoUninitialize must be called manually before using any of the dbGo objects. Failing to call CoInitialize will result in the CoInitialize was not called exception. The CoInitialize method initializes the COM library on the current thread. ADO is COM.You *cannot* use the TADOConnection object from the main thread (application). Every thread needs to create its own database connection.You must use the Synchronize procedure to talk to the main thread and access any controls on the main form.

Minicase-8 - Essay Example However, under the ED, only those conversion options that â€Å"establish an ownership relationship will be classified as equity† (ED-FI, p. 4). This means that, once converted, the shares are not redeemable and that the holder bears the risk of the changes in the market value of the issuer’s shares of stock. If the option does not meet this criterion, the entire convertible bond will be classified as liability. Prior to the issuance of SFAS 145, the standard used to account for early extinguishment of debt was FASB Statement No. 4, Reporting Gains and Losses from Extinguishment of Debt. Under Statement No. 4, the gains or losses realized from the early settlement of debt should be shown as part of the company’s extraordinary items in its income statement. This classification is required regardless of the reason behind the early settlement. Under SFAS 145, gains or losses from early extinguishment of debt can now be classified as part of the income or loss from continuing operations in the income statement; provided that early extinguishments of debts are part of the recurring transactions for the issuer. However, if such early extinguishments of debts are unusual or are infrequent transactions, the gains or losses realized from such early extinguishments should still be classified as extraordinary items in the income statement. The change was made because FASB recognized that early payments of debt have become part of the risk management strategy of certain companies. Such transactions are now also viewed as recurring financing activities that an entity can utilize to manage its interest rate risk. FASB also thinks that this change is consistent with the definition of unusual or extraordinary transactions under APB Opinion No. 30 and will reduce the frequency of using the caption â€Å"extraordinary items† in t he income statement. The requirement of SFAS 145 related to the classification of gains or losses from early extinguishment of debt affects

For this reason, the rights of the earth are followed for the nature, but not for the benefits and value that nature and the laws have towards humans. This means that representations of the legal rights of the earth are determined by the value that nature bears independently, and without influence from the interests of humans. In addition, all aspects of nature that fall in the sphere of moral concern and moral relevance bear a considerable amount of influence on decisions made about the environment. For this reason, they are crucial for ethics that are affiliated to the environment concerning the care that all humans should give to it. This is in addition to legal action and frameworks affiliated with the environment in cases of violation of requirements put in place to safeguard the environment and all its affiliated aspects in relation to sustenance of life (Philos 316). It is for the legal status of the environment that ethics are observed to the point of passing legislation on a global scale aimed at protecting the interests of nature and its constituent parts as are similarly held for humans. This translates to individual legal representation of the earth’s interests that are similar to the universal declaration of human rights. The other aspect of environmental aspect is the religious angle affiliated to it in regard to the problems that the environment faces according to the guilt associated with it due to a number of substantial reasons. These include the destructive alliance formed by science, technology, and democracy, which have seen the destruction of the earth (environment) in the name of development. The Christian religion in the west has pioneered the destruction through cosmology, where man views himself as a separate entity from nature. In turn, this has led to the domination of the earth by man in a quest t o attain their destiny (Jenkins 284). In relation to the aspect of religion and environmental ethics, man takes himself as taking precedence over nature due to their perceived differences, which is an aspect that is condemned by some religions and especially Buddhism and the philosophies for which it stands. Buddhism, concerning environmental ethics, stands for the belief that since the world will decline it is crucial to safeguard it. It does this by showing its followers how important the different aspects of nature are to the existence of humanity thus addresses issues of ecology and the environment (Keown 97). This also occurs through the cosmic beliefs based on tradition. For this reason, Buddhism’s ethics area call for prudential measures to conserve the environment for harmonious coexistence and support life, which makes it a moral obligation to look after the environment as is the case with the universal declaration of the rights of mother earth. However, religion as a whole does not support its ethics sufficiently due to the constant conflict between issues of technology, science, and religious beliefs. Climate and resource management is also an ethical issue that affects the environment on multiple scales. This is concerning the challenges that policymakers, scientist and researchers are faced with in creating solutions to overcome environmental problems. In addition, they grapple with issues of
