Physiology for health - Essay Example 4. Describe the mechanisms involved in regulation of energy metabolites? 5. Explain the role of the hormones involved in controlling glucose level? 6. Describe the role of structures in controlling carbon dioxide and urea? Homeostatic Mechanism Homeostatic mechanism happens in an attempt to balance the internal environment of the body despite the changes in temperature of the internal and external environment. To achieve such condition, the temperature and chemical compositions of the person’s fluid environment has to remain constant (Thibodeau & Patton, 2004). Thus, in events where there are disturbances of the homeostatic condition of the body, specific regulatory mechanisms responds to adjust the different body systems for the person to get back to its homeostatic state. The body adapts the self regulatory mechanism as a way to homeostasis. For instance, if a person’s temperature greatly fluctuates from the set point which is 37 degrees centigrade, the regulatory sys tem that controls body temperature use negative feedback to correct the temperature to bring it back to the set point. The same holds true in chemical changes where glucose and gases such as carbon dioxide and oxygen has to be maintained if the person is to survive. However, in this case, there is a gap for hormonal homeostasis to be corrected because chemical substances of the body take time to diffuse and circulate into the blood stream. Osmoregulation and Thermoregulation Process Homeostatic mechanism works to regulate the osmoregulation process through the kidneys that regulates the water and electrolytes that leaves the blood so that it equals the amount that enters. To process blood plasma and to form urine, the mechanism of filtration, tubular re absorption and tubular secretion has to take place. These mechanisms start when the water and solutes free of protein moves from plasma to the tubules of the Bowman’s capsule. As they pass through the tubules, water and import ant solutes are reabsorbed while molecules that move out of the blood are excreted. This process not only prevents water loss or retention but also maintains sodium and potassium content as well as the desirable ph level of the blood. Thermoregulation is also regulated by homeostatic mechanism with the negative feedback of the muscles. Stimulus from the outside environment is perceived by the affectors and is relayed to the hypothalamus where it is compared with the â€Å"built in† body set point. The result of the interpretation of the hypothalamus will be sent back to the effectors for the body to act appropriately. For example, when a person is exposed to cold weather, the skin and blood vessels picks up the signal and is sent to the hypothalamus which is interpreted as something that threatens the temperature. As a result, it sends nerve signal to the muscles to shiver to produce heat. Once the body temperature is regulated, the hypothalamus stops its stimulation of the e ffectors. Functions of Cardiovascular and Respiratory systems in regulating body Mechanism The function of the cardiovascular and respiratory systems regulates body mechanism by transporting hormones and nutrients , cleansing waste body products such as carbon dioxide and providing the body with fresh supply of oxygen as the blood circulates within the structures of the heart and lungs. As the blood is propelled to enter the right side of the

Emerging market Essay Example | Topics and Well Written Essays - 1500 words

Emerging market - Essay Example A developing or emerging market is one characterized by high industrial growth. This implies increase in the industrial output and India has been going through rapid industrialization. It has seen a growth of around 27% percent in Industrial output which is second only to China. Growth in Industrial output means a great deal of wealth is being generated and looking at the statistics we can see that as a result this wealth generation there was a need of an organized financial system. As a result of the unprecedented growth that India experienced, many financial firms including banks, insurance companies, consumer banking firm sprouted to serve the increasing needs of Indians in order to properly utilize their newly-earned wealth. (Lei, 2007) Another feature of an emerging market is proper governance and India is being governed by a very rational and open-minded parliament. Some credit also goes to Indian army for that as India has never faced Military coups or any other embarrassing situation like that where power is snatched from the representative of the people and given to one sole dictator. This economics stability has earned India a title of "Largest democracy in the world". One must keep in mind is that economic stability is imperative for fast growth. The reason behind why countries around India who are blessed with the same natural characteristics as India and high populations have never been able to reach the level of India, when it comes to economic growth. Almost all countries surrounding India suffer from instable political system and periods of military coups occasionally, but the real credit goes to patriotic Indian army, which has never been temped into launching a coup against their own people. This has earned India a escalated position not only in the Asian economics but also in the world economics, where Indian case studies adorn the history, present and future. (theindianpolitics, 2009) A land of around 1.5 billion people, India's climb in the social and economic spheres has been tremendous over the past few years. During this time, India has grown from strength to strength. Proving all its doubters wrong, India is reaching great new heights at a very fast pace. This growth of India is not confined only to their economy, but let it be any facet; India is growing rapidly in an attempt to escalate to nadir. India is leaving its mark on just economic progress and development but all sphere of life or all fields where it can grow any further. For example, social growth of India can be judged by the fact that entire Asia is intimating European culture, but Europe and Western Nations are intimating India's culture. India's film industry, "bollywood" has penetrated western market and became the second largest film industry of the world after Hollywood. This great success of bollywood and Indian culture has given India exposure to far flung areas and contributed heavily in the recognition of India all around the world. As a result of all this factors and blessed with tremendous amount of useful natural resources, such as cheap and skilled labor, tropical climate, great fertile land etc. (Vyas, 2003) India has become a business hub and all trading and business activities are diverting towards India. Owing to all these factors and great trust shown by the foreign investor towards India, Bombay Stock Market is growing around 17% annually which is comparable to the richest stock markets like New York Stock Exchange (NYSE)

George Mead Theory Essay Example for Free

George Mead Theory Essay â€Å"the self is something which has a development; it is not initially there, at birth, but arises in the process of social experience and activity, that is, develops in the given individual as a result of his relations to that process as a whole and to other individuals within that process.† * was an American philosopher, sociologist and psychologist, primarily affiliated with the University of Chicago, where he was one of several distinguished pragmatists * He is regarded as one of the founders of social psychology and the American sociological tradition in general. * Mead is well-known for his theory of the social self, which is based on the central argument that the self is a social emergent. * Mead’s most widely read work, Mind, Self and Society, gives priority to society over the mind and highlights the idea that the social leads to the development of mental states. * Mind is a process, not a thing, and it is found in social phenomena rather than within individuals. * The self occupies a central place in Mead’s theory. * Self is essentially a social structure and it arises in social experience. It is the unique combination of the roles and individual play in relation to others – the complex blending of individual motivations and socially desirable responses. * The self consists of an â€Å"I† which the active side and as object, called â€Å"me†. * Infants begin with no self. As they learn to use the language and other symbols, the self emerges through play which involves taking the roles of significant others. * Gradually children move from simpler games to more complex ones involving others such as team sports. Mead called this generalized others to refer to the general cultural norms and values people use as references in evaluating others. * Mead defines self as the ability to take oneself as an object and identifies basic mechanism of the development of the self as reflexivity the ability to put ourselves into the place of others and acts as they act. * Self can arise only through social experiences, and the traces its development to two stages in childhood: the play stage and game stage. * Play stage – children learn how to take the attitude of particular others themselves. * Game stage – children learn how to take the role of many others and the attitude of the generalized other. * I – is the immediate response of an individual to others; it is unpredictable and creative aspect of the self. * Me – is the organized set of attitudes of others that an individual assumes; it is how society dominates the individual and is a source of social control. Mead’s theory on social self * The social conception of the self entails that individual selves are the product of social interaction and not the logical or biological preconditions of that interaction. It is not initially there at birth but arises in the process of social experience and activity. * Language – allows individuals to take on the â€Å"role of the other† and allows people to respond to his or her own gestures in terms of symbolized attitudes of others. * Is communication via â€Å"significant symbols† and it is through significant communication that the individual is able to take the attitudes of others toward his/herself. Language is not only a â€Å"necessary mechanism† of the mind, but also the primary social foundation of self. * Play – individuals take on the roles of other people and pretend to be those other people in order to express the expectation of significant others. * This process of role-playing is the key to generation of self-consciousness and to the general development of the self. * In the play, the child takes the role of another and acts as though he/she were the other. This form of role-playing involves a single role at a time. Thus, the other which comes into the child’s experience in play is a â€Å"specific other† * Game – individual is required to internalize the roles of all others who are involved with him or her in the game and must comprehend the rules of the game. * Is the stage of social process at which * Generalized other- organized and generalized attitude of a social group. * consists of a composite of all those who contribute and participate in ones society * The individual defines his or her own behavior with reference to the generalized attitude of the social group(s) they occupy. When an individual can view him/herself from the standpoint of the generalized other, self-consciousness in the full sense of the terms is attained. * Me – represents the expectations and the attitudes of others (generalized others). It is the organized set of attitudes others that the individual assumes. * Is the social self * The organized set of attitudes of others which one himself assumes * is that part of the self which comes about as a result of the individuals internalization of societys values and behavior expectations * I – is the response to the â€Å"me†, or the person’s individuality. * Response of the organism to the attitudes of others * is that part of the self which is spontaneous * Self – develops by internalizing the norms of one’s society * Significant other are those with whom the individual has an important relationship

Categorical imperative described by Immanuel Kant

Categorical imperative described by Immanuel Kant The Categorical Imperative which was initially described by Immanuel Kant is the theory that a person is to act only on the maxim through which you can at the same time will that it should become a universal law (ONeill, 1993, p.177). He believed that individuals are able to behave in a moral way due to their ability to think rationally and freely when making choices. He felt that a persons moral duties are categorical imperatives, in that our morals tell us how we ought to act. He stressed that these moral duties command us to take certain actions thus giving us the word imperative (Smith, 2010). Kant also felt that these moral responsibilities are relevant to individuals because of their rationality and because individuals have the ability to make their own decisions apart from others influence. The role of his categorical imperative within Kants ethics will be discussed in this essay as well as the limitations to his theory, leading to the conclusion that the categorical imperati ve may be a guiding ideal, but cannot be universally and fairly applied in the real world. Kants ethics seem grounded in the basis of the idea that we each have rights to freedom, autonomy and democracy. Because these rights are ours, we therefore have the ability to make free, rational and moral choice. We can determine our duty through our ability to reason. Kant contends that the categorical imperative begins with the premise that human beings have a free will and that ability to reason (ONeill, 1993, p.175). Kants explanations make sense because he argued that in order to act morally, it was necessary for one to first be free to have the choice of being moral or immoral (Smith, 2010). He also felt that as rational beings, individuals are compelled through their rationality to follow norms and requirements in society, thus our reasoned morality follows a set of internal laws which will then govern our actions. In Kants view, morality is characterized by the ability to universalize (ONeill, 1993, p.177). If a choice or action cannot be universalized across all agents, then it is irrational, unreasonable and therefore immoral. These choices or decisions can be called maxims, so a universalizable maxim is a moral maxim (ONeill, 1993, p.177). In contrast, subjective maxims are those which are not binding or applicable to all people and which cannot guide the actions of the moral, rational individual. So with the cornerstones of rationality and universalizability at the base of Kants categorical imperative, we add his views on duty and good will. To Kant, morality is based on the intent not on the action or outcomes of those actions. Acting with good will is acting with duty to others, through of course the reasoned conclusion that this duty is moral. According to Kant, this was the foundation of overall good. He highlighted the fact that â€Å"one cannot use action to judge whether a being was good or bad because sometimes some good actions may be an avenue for committing evil acts† (Smith, 2010). For example, to donate your money or possessions to others could be considered a good or worthy deed. However, if that donation is actually done to gain a heightened profile in the community or to hide resources from the government, then this will undermine the seemingly good act. Whether or not the action is good comes down to the intent of the individual, not the outcome. The connection can therefore be made that Kant characterized inherent good as good will, meaning that if one has pure intentions at the commencement of a n activity, then no matter the result of that activity, the individual would be considered to be good and duteous, as they have removed â€Å"empirical ego† from the decision (Schroeder, 2005, p.19). The categorical imperative therefore gives us the ability to decide if an action is a moral or immoral one, in that it tells us to make our decisions not on our desires or expected outcomes, which would be hypothetical, but by making a decision which is the right, moral or categorical imperative (Smith, 2010). This is not a simple answer, as the categorical imperative is a way of leading us to decision making which is considered and which demands we assess our motivations for those decisions. To apply Kants categorical imperative in a practical way, he offers four formulations to aid in its understanding. The first is the formula of universal law which states â€Å"act only in accordance with that maxim through which you can at the same time will that it become a universal law† (Kant, 1998, p.31). As stated earlier in this essay, this formulation relates to the universability principle. The second is the formula of the law of nature and asks us to â€Å"act as if the maxim of your action were to become through your will a universal law of nature† (Kant, 1998, p.31). This formulation relates to the parallels between the laws of nature and moral law. The third formulation of his imperative is of humanity and asks that you â€Å"act in such a way that you treat humanity, whether in your own person or in the person of another, always at the same time as an end and never simply as a means† (Kant, 1998, p.37). This describes his respect for others and our n eed in moral action to act well towards others in a universal manner. His fourth and final formulation for the categorical imperative is that of autonomy. It states that our actions are to be guided by â€Å"the idea of the will of every rational being as a will giving universal law† (Kant, 1998, p. 39). This principle of autonomy includes the concept of free and rational choice, as well as the capacity to compare and evaluate differing options. Unless directed by good will, autonomy is an ideal which will not be achieved in Kants theory. There are limitations to the belief that moral requirements must be categorical. Kants own writing on the issue of lying shows a much debated weakness to his theory. In refuting a French philosopher who maintained that truth was only a duty if it did not injure others, Kant stressed that truth was a duty in and of itself. However great the disadvantage to self or others, Kant believed that the categorical imperative demanded truth in all human action that it in fact was a sacred decree of reason (Kant, 1994, p.281). The consequences of an action held little interest for Kant, as it was in the morality of the decision or action that he held forth. Yet the implications of such a rigid and insensitive view of the actuality of human existence make Kants theory of categorical imperative unrealistic (ONeill, 1993, p.182). When a person obeys the categorical imperative, they are working within an ideal which presents them with the choice to make independent, ethical decisions (Katchy, 2007). One can only have this choice if the idea of freedom of thought and action accompanies a lack of fear of â€Å"authoritarian repercussion for not conforming to the will of another† (Katchy, 2007). Kant believed that forefront on the minds and consciousness of people, should be their own self-interest, and that republics should be established, where law would be adopted by the citizenry over violence. This would support his belief that due to the categorical imperative to act morally, these republics would lead to the possibility of peaceful existence (Schroeder, 2005, p.20). Whilst it may seem logical to some that all individuals are rational and level-headed because we as Kants individuals have the capability to use such rational and level-headed ideas to guide our actions, the truth is that reality has lit tle bearing on Kants ideals (Katchy, 2007). Kant presented sound theory which not only is used today by many, but was far-reaching for a theorist of the 1900s. His theories would by many be termed as simple common sense in todays world and the categorical imperative offers clear counsel for those who wish to place an underpinning theory to their day-to-day decision making. With an â€Å"absolute and detailed necessity of making sure that a person exercises their own will and does not conform to the ways of others† (Katchy, 2007), Kantian morality has an attitude that can be found in modern times. Individuals are able to rely upon logic to guide their actions in a rational way, but rationality is not due to logical behaviour. Kants theory is relatively simplistic, be your own person, act morally and do not simply act as others tell you to, but with your own thought and evaluation (Katchy, 2007). It is also quite clear in confirming the distinction between understanding the duty towards self and our responsibilities towar ds others. As a utilitarian however, the categorical imperative is not a sustainable view. As utilitarians, we must take into account the consequences of our actions and decisions and the impact of these actions or decisions on others. Kants murderer at the door is a prime example of how the outcome of lying is so much better than of telling the truth the correct response was to lie. But as an ideal to aspire to, the theory of the categorical imperative is a powerful one (Katchy, 2007) which transcends time or geography, upon which one can establish their own moral foundation in a world which can be confusing and contradictory.

Soliloquies Essay - A Powerful Soliloquy in Macbeth -- Macbeth essays

A Powerful Soliloquy in Macbeth The play ‘Macbeth’ uses soliloquies with great effect to express the thoughts of individual characters, particularly in the case of the protagonist, Macbeth. In Act V Scene V, strong words from Macbeth convey to the reader two themes of the play.   This soliloquy demonstrates the play's use of irony and the use of the disparity between the great opposition of light and darkness as symbols for both life and death.   This soliloquy is quite significant to the play as a whole since it demonstrates two very important themes as well as leading to a better understanding of Macbeth. Macbeth is talking to an officer, when hearing of his wife's demise his mood suddenly deepens into that of emptiness.   He begins a soliloquy and states a number of ironic things.   He states that life drags on, that it "creeps in this petty pace" when in reality the speed of his actions and the development of the play's plot are taking place at a great speed.   Furthermore he goes on to describe life as a "brief candle," thus communicating that life’s opposite; death must therefore be an eternal darkness.   Throughout the play, the character Macbeth has longed for death, perhaps so that he can be unleashed from his worldly pain and guilt.

Peer-Reviewed Article: Heart Disease Essay -- Article Review

There are many reasons I have used health care services at different times in my lifetime from birth to the present time. I have utilized pregnancy healthcare services. I have used health care services for preventive care such as a yearly Pap smear or health physicals. My friends, family and my co-workers may use health care services for the same reasons as mine, especially if they are of the same gender. The peer-reviewed article that I chose was about heart disease. Heart disease needs particular attention from health care administrators, since â€Å"Chronic heart failure (CHF) is a progressive syndrome that results in a poor quality of life for the patient and places an economic burden on the health care system†. (Ramani, Uber, & Mehra, 2010). There is no one test to diagnose heart failure. Hypertension increases the risk of heart failure 2 to 3 fold. (He, et al, 2001) The American College of Cardiology (ACC) has identified 4 stages of heart failure. (Hunt, Abraham, Chin et al, 2009). Screening patients for heart failure is sometimes controversial. Health care administrators...

Slavery In the North and South

Contrary to what many people in this country believe, slavery took place in the North and the South. In fact, Massachusetts was the first colony to legalize slavery. By the year 1700, Rhode Island had surpassed Massachusetts as the chief importer of slaves in the north. Major slave ports included Boston, Salem, Providence, and New London. The tariffs that were enforced upon slave imports were used to pay for community projects, such as repairs to roads and bridges. At the beginning of importing and exporting Africans, slavery disguised itself as indentured servitude.But the reality was that indentured servants, of African origin, were often turned into slaves against their will and against the contract they had signed to enter to the New World. Indentured servitude became outdated and old-fashioned due to the fact that the general society was uncomfortable with allowing former servants to purchase land after their contract expired. Another reason for this is due the fact that servant s were much more expensive to replace than slaves. Lastly, making black slaves gave an easily identified mark— one skin color determined who the horse was and who the king was.Slavery existed in New York, Philadelphia, New Jersey, Massachusetts and the other Northern states. Famous Northerners, such as John Hancock, Benjamin Franklin, and William Henry Steward (the 24th secretary of state, in President Lincoln’s cabinet) were slave-owners. Although slaver was abolished in New England by 1804 slavery continued in the northern colonies for another 80 years. Northerners profited from slavery in many ways. New England’s manufacturing empire was based on shipping and their shipping money was acquired through the trading of slaves.Without a workforce as large as the slavery had offered, the towns, cities and companies would have taken sustainably longer to develop and prosper in the way that they did. The poor, landless white indentured servant was a problem for the c olonial establishment elevating them above the African slave solved two problems: African slaves were more abundant and easy to come by, and the landless hapless white servant now had a reason to feel superior. The white indentured servant could vent their hostility at the Africans and thus provided the upper class with a buffer.This led to an eventual phasing-out of indentured servitude, and the rise in slavery. An example of how fearful the colonial establishment was of the rising dissatisfaction that the landless felt was the Bacon Rebellion of 1676. Here slaves and Indentured servants got together and tried to overtake the planters of Virginia. The reason why slavery was abolished in the North had more to do with the expense associated with keeping slaves and with the need for the economy to have workers who could fuel the needs of the industrial revolution.The north did not have a large-scale agrarian society so slavery did not come to be relied upon the same way it was relied upon in the south; Slavery also lost its hold in the North because of the Revolutionary War with Britain. As Britain moved throughout the newly created United States of America, it freed the slaves, using them to help Britain wage its war against the new founded country. The puritan influence was also a factor in the freeing of slaves. The idea that freedom should be accessible to all came into conflict with the concept of slavery.However, it is also clear that the Puritan ethic led Northerners to erase their hand in the slave trade. Ultimately, this ability to forget their part in the slave trade led the Northern colonies to believe that the southern slave system was alien and set apart from their own lifestyle. The north was less conducive to farming. However, for the most part, this was the mainstay of families in the northern colonies. Towns were built around these farms and these towns produced areas for other industry.The church, the general store, and the entertainment indust ries of bars and hotel services all grew up alongside the farming community. Because the northern colonies were along the coastline, many industries were built up around living life near the water. To earn a living, people engaged aquatic activities in fishing, whaling, and shipbuilding. Because the land was so unsuitable for large scale farming, the northern colonies developed different than their warm, southern counterparts. Fur trading and timber were large enterprises in the Northern colonies.The harsh conditions also made it necessary that every member of the family be a part of the family’s survival. Children were not educated formally unless they were from the upper class of society. However, every white person was expected to know and be able to read the Bible. Religion was an important center of community life. The church established both secular and religious law, and enforced both. It is no surprise that higher education started in the North, with Harvard opening i n 1636. The northern states were made of people from England and the Netherlands.As a  result, the architecture, clothing, types of food enjoyed, and social activities differed from their southern counterparts. In New England for instance, stones were used to build cellars so that one could have frost free winter storage. The layout of the home was to maximize warmth from the fireplace and slope of the roof was made to compensate and distribute the weight of heavy snowfall. The northern treatment of slaves was also influenced by the British and Dutch cultures, often seemingly less harsh in their treatment of servants and slaves than their French and Spanish competitors in the south.Family life was also culturally influenced with men hunting, fishing, and tanning animal hides to make clothing. Women and children worked inside the home making textiles and preparing food. In the south, everyone had to be on hand to plant and harvest crops and thus the division of labor seemed much di fferent than in the South. The conditions under which the northern and southern colonies developed were vastly different from one another. Culture, geographic location, religious, and philosophical differences produced two distinct economic and social systems.However, it is very clear that slavery was the constant thread through which businesses flourished and many colonists got rich. The slave trade continues to be a shameful mark upon all the achievements that occurred in the Colonial Americas and in the United States. Slavery’s abolishment came as a result of economic necessity rather than moral indignation and any attempt to forget this devalues the horrors that slavery inflicted on the African people who came to the New world.
