Perceptions of Mental Illness Essay -- Biology Essays Research Papers

Perceptions of Mental Illness Throughout this course, much of what we have discussed has depended strongly on an interpretation of scientific information. We have questioned, criticized, accepted, rejected, and formed our own ideas about topics in neural and behavioral science. A book which I have read recently seems to fit in with this type of discussion. Blaming the Brain, by Eliot Valenstein, describes the major biological theories of mental illness and the lack of evidence we have to fully support them. What Valenstein argues is that we have come to a point where we accept all mental illness as purely biological in origin, and have discarded older ideas about social and psychological effects, rather then attempting to see how these two different types of explanations fit together. While some may argue that this shift has helped to significantly de-stigmatize mental illness, it also has caused a neglect of important factors which must play a role in these disorders. In 1999, in a report by the Surgeon General, it was stated that research into the biology of the brain is "a potent antidote to stigma," but it was also emphasized that psychotherapy not be forgotten as it sometimes plays a large role in recovery. Finding middle ground: Although we do not know all there is to know about disorders of the nervous system, I believe that it is very plausible that mental illness is mostly the result of disturbances in the nervous system. Although in extreme situtions, some claim things like, "it reduces a complex human activity to a slice of damaged brain tissue" (4). I wouldn't go this far to assume that this is all there is to it, although I also don't believe that all mental illnesses can fit into the same box.

Consumer negotiation Essay

Introduction Negotiations have a significant impact on the savings of a customer during the business relationship. The authors of this article assume that the transfer price lies between the manufactures production costs and the maximum retail price and that the negotiations occur in an incomplete and the producer is not sure on the consumer price. Every negotiator has the ability to convince the other that the surplus is smaller than it real is. The article also uses the game-theoretic model (Perry & Grossman 1986)  Ã‚   to predict the outcomes and behavior in a negotiation scenario.   In both experiments described by this article fail to describe the bargaining outcomes and behaviors since the players took too much time to agree.   The authors conclude that the negotiation mechanisms depend on the economic characteristics of the negotiation situation and that social and individual contexts influence the outcome of the consumer negotiation.

Conventional Morality Essay

Lawrence Kohlberg: â€Å"Physical consequences of an action determine its goodness or badness regardless of the human meaning or value of these consequences. Avoidance of punishment and unquestioning deference to power are valued in their own right, not in terms of respect for an underlying moral order supported by punishment and authority. † (Duska, R. and Whelan, M. , 1975) Summary: The concern is for self – â€Å"Will I get into trouble for doing (or not doing) it? † Good behaviour is associated with avoiding punishment. Inadequacy of Stage 1 reasoning: Avoidance of punishment regardless of the ethical value of the actions is unhealthy especially under â€Å"bad† authorities such as Adolf Hitler. * Stage 2: Instrumental Relativist Orientation Lawrence Kohlberg: Right action is â€Å"that which instrumentally satisfies one’s own needs and occasionally the needs of others. † â€Å"Human relations are viewed in terms like those of the marketplace; elements of fairness, reciprocity and equal sharing are present, but they are always interpreted in a physical or pragmatic way. Reciprocity is a matter of ‘you scratch my back and I’ll scratch yours,’ not of loyalty, gratitude or justice. † (Duska, R. and Whelan, M. , 1975) Summary: The concern is â€Å"What’s in it for me? † It is still egocentric in outlook but with a growing ability to see things from another person’s perspective. Action is judged right if it helps in satisfying one’s needs or involves a fair exchange. Inadequacy of Stage 2 reasoning: Where the needs of different individuals conflict, can there ever be a fair exchange? Doesn’t this conflict call for sacrifice from one of the parties? Level 2 – Conventional Morality People at this stage conform to the conventions / rules of a society. * Stage 3: Good Boy-Nice Girl Orientation Lawrence Kohlberg: â€Å"Good behavior is that which pleases or helps others and is approved by them. There is much conformity to stereotypical images of what is majority or ‘natural’ behaviour. Behavior is frequently judged by intention. ‘He means well’ becomes important for the first time. One earns approval by being ‘nice. ‘† (Duska, R. and Whelan, M. , 1975) Summary: The concern is â€Å"What will people think of me? † and the desire is for group approval. Right action is one that would please or impress others. This often involves self-sacrifice but it provides the psychological pleasure of ‘approval of others. ‘ Actions are also judged in relation to their intention. Inadequacy of Stage 3 reasoning: * Same person, different roles OR Different groups, different expectations * Different people, different roles * People not living up to their duties or roles * Stage 4: Law and Order Orientation Lawrence Kohlberg: â€Å"Right behavior consists in doing one’s duty, showing respect for authority and maintaining the given social order for its own sake. † A person in this stage â€Å"orients to society as a system of fixed rule, law and authority with the prospect of any deviation from rules as leading to social chaos. † (Duska, R. and Whelan, M. , 1975) Summary: The concern now goes beyond one’s immediate group(s) to the larger society †¦ to the maintenance of law and order. One’s obligation to the law overrides one’s obligations of loyalty to one’s family, friends and groups. To put it simply, no one or group is above the law. Inadequacy of Stage 4 reasoning: * Unquestioning obedience toward authority is unhealthy. * Accepted social order may not be the best possible order. The laws of society may even be bad. Level 3 – POSTConventional Morality The moral principles that underline the conventions of a society in this level are understood. * Stage 5: Social Contract Orientation Lawrence Kohlberg: â€Å"Generally with utilitarian overtones. Right action tends to be defined in terms of general individual rights and in terms of standards which have been critically examined and agreed upon by the whole society †¦ with an emphasis upon the possibility of changing law in terms of rational consideration of social utility (rather than rigidly maintaining it in terms of Stage 4 law and order). † (Duska, R. and Whelan, M. , 1975) Summary: The concern is social utility or public interest. While rules are needed to maintain social order, they should not be blindly obeyed but should be set up (even changed) by social contract for the greater good of society. Right action is one that protects the rights of the individual according to rules agreed upon by the whole society. Inadequacy of Stage 5 reasoning: How do we arrive at a consensus on the rules that are good for society? Should a majority group impose their preferences on a minority group? What if you disagree with the decision of the majority? * Stage 6: Universal Ethical Principle Orientation Lawrence Kohlberg: â€Å"Right is defined by the decision of conscience in accord with self-chosen ethical principles appealing to logical comprehensiveness, universality and consistency. These principles are abstract and ethical (the golden rule, the categorical imperative) and are not concrete moral rules like the Ten Commandments. At heart, these are universal principles of justice, of the reciprocity and equality of human rights, and of respect for the dignity of human beings as individual persons. † (Duska, R. and Whelan, M. , 1975) Summary: The concern is for moral principles †¦ an action is judged right if it is consistent with self-chosen ethical principles. These principles are not concrete moral rules but are universal principles of justice, reciprocity, equality and human dignity. Inadequacy of Stage 6 reasoning: Our conscience is not an infallible guide to behaviour because it works according to the principles we have adopted. Moreover, who or what determines these universal principles? Although moral reasoning does not necessarily lead to moral action, the latter is based in part on one’s capacity to reason about moral choices. Kohlberg was more concerned with the reasoning of the action than the action itself. And that reasoning when acted upon becomes our motivation. II – ETHICAL RELATIVISM * Cultural Relativism (sociological relativism): The descriptive view that different groups of people have different moral standards for evaluating acts as right or wrong. A. Hence, it is not an ethical doctrine–it’s a sociological or observational conclusion–even so; the view is somewhat ambiguous. B. For example, different groups might have the same basic moral principle, but apply the principle in radically different situations. 1. A second sense of cultural relativism is less obvious. I. e. , that different cultures differ on basic moral principles. 2. A possible reason for the observation of cultural relativism is shown by the example of basic moral principles which could be said to support different moral rules according to the interpretations of different cultures. In the following diagrams, there are two vastly different interpretations listed for each moral principle. * Ethical Relativism: the prescriptive view that (1) different groups of people ought to have different ethical standards for evaluating acts as right or wrong, (2) these different beliefs are true in their respective societies, and (3) these different beliefs are not instances of a basic moral principle. A. The ethical relativist often derives support for his position by two basic mistakes: 1. The relativist confuses cultural (or sociological) relativism with ethical relativism, but cultural relativism is a descriptive view and ethical relativism is a prescriptive view. (E. g. , cultural relativismdescribes the way the way people actually behave, and ethical relativism prescribes the way people ought to behave. 2. The ethical relativist often argues as follows: â€Å"An absolute ethical standard has never been proved beyond doubt in the history of thought. Thus, an absolute ethical standard does not exist. † This argument is an instance ad ignorantiam fallacy. p is unproved; not-p is true. From the fact that a statement has not been proved, we can logically draw no conclusion. B. Objections to ethical relativism. 1. The Differing Ideals Objection (or, as it is sometimes called, the linguistic objection): it is inconsistent to say that the same practice is considered right in one society and considered wrong in another. (If â€Å"right† and â€Å"wrong† are to have consistent meaning, then the terms must be used in the same manner. ) Possible counter-objections (by the ethical relativist): a. The relativist sometimes states that â€Å"right† and â€Å"wrong† have no consistent meaning. These words reflect only emotion or perhaps the ceremonial use of language. In other words, this defense shades into ethical subjectivism. Counter-counter-objection (by ethical absolutist): The problem with believing that â€Å"right† and â€Å"wrong† have no consistent meaning is the ordinary use of words in this case results in meaninglessness. What would happen if people used the same word in different situations to refer to different things? Communication would not take place. b. Some ethical relativists believe ethical words are reducible to non-ethical values; e. g. , these words have to do with recommendations for survival or well-being. Counter-counter-objection (by ethical absolutist): the problem here is just the difficulty of understanding the nature of a non-ethical value. Would a non-ethical value be an aesthetic value? c. Some relativists believe we can justify relativism by intuition, revelation, authority, etc. Counter-counter-objection (by ethical absolutist): these attempts are subjectively based; they differ from time to time and place to place. 2. Mental Health Objection to ethical relativism (from the definition or criterion of a group): If â€Å"what is right in one group is wrong in another,† where exactly does one group end and another begin? Counter-objections to the Mental Health Objection (by the relativist): * Right and wrong are to be determined in the situation. * Right and wrong are to be determined by what the majority determine at the time and place. * Right and wrong are ultimately established by power or authority. 3. Ad Populum Objection to the relativist’s belief that ethics is established by what most people believe: Simply because most people think something is right does not thereby make it right. Simply because most people think a statement is true does notmake that statement true Counter-objections to the ad populum objection (by the relativist): a. The same difficulty of establishing the meaning of â€Å"right† and â€Å"wrong† exits for the absolutist, pari passu. The absolutist has been unable to state a universally agreed upon meaning to the terms. (Notice that this response is a variant of the ad hominem—tu quoque.) b. Other solutions to the questions of the meaning of key ethical terms according to the relativist are possible by appealing to survival value, consensus gentium, and so on 4. Moral Progress Objection: If ethical relativism were correct, there could be no such thing as moral improvement or purpose in cultures or a person’s life. To have improvement, we must have a standard by which to judge the difference in moral values. Counter-objections (by the relativist): a. That’s correct–we can make no such judgment that one society is better than another. We could only judge by our own values. b. If something like â€Å"survival value† is used to ground moral beliefs, then moral improvement might be identified with â€Å"increased knowledge concerning survival of the society. † * Ethical Absolutism: the prescriptive view that there are basic or fundamental ethical principles which are true without qualification or exception as to time, condition, or circumstance. * Ethical Nihilism: the view that ethical terms such as â€Å"right† and â€Å"wrong† have no meaning or are nonsense. A. Objection: but something is meant when we say, â€Å"X is wrong. † Counter-objections (by the nihilist): 1. If there is no empirical meaning to the terms, they have no â€Å"cash value. † (Q. v. , positivism. ) 2. â€Å"Whatever can be said, can be said clearly. † The burden of proof that the terms have meaning is on the non-nihilist. * Ethical Skepticism: the view that ethical terms such as â€Å"right† and â€Å"wrong† might have meaning but their meaning cannot be established. A. Objection to skepticism at this point is methodological. Ethical skepticism should not be held a priori at the beginning of an investigation but should only be a possible outcome after a thorough study.

Looking back looking forward essays

Looking back looking forward essays The policies, acts and legislations aimed at inclusion or exclusion of First Nations have had an enormous impact on the development of Fist Nation organizations in Canada. The fact that the process of colonization and nation building did not included consultation with or respect for the culture, tradition, sovereign or organizations of First Nations drove this oppressed group to form political and non-political lobbying organizations. Prior to the arrival of European new comers, First Nations people had organized societies. These societies had law, tradition, culture, leadership and religion. Their concept of sovereignty was intangible, an inherent feeling of reverence of land, the mother from which life came and that that land should be preserved for future generations, as it had been since time immemorial. First Nations believe that they live with the land, not simply on it. The Federal Government and Aboriginal peoples understand the definition of Sovereignty differently, each t aking the understanding from two different directions. However, the most crucial issue in this paper is the treatment and understanding of the policies, acts and legislations that affects the plight of aboriginal peoples of Canada. Through this essay it is hoped an understanding of how the policies and treatment of these people lead to the desire for self-government and self-determination and development of Aboriginal political organizations. Comparison of settlements of government and aboriginal peoples across the country it might be better understood why certain policies, acts and treaties caused certain movements with in aboriginal regions and territories. The stages of growth of both government and aboriginal societies and nations took many turns with events of government attempting to assimilate these people into a European culture. Indian agents were introduced to the aboriginal communities in the early 1800s. Their mandate was to live in a...

Nudibranch Facts

Nudibranch Facts Enchanting to both divers and scientists, colorful nudibranchs (pronounced nooda-bronk and including Nudibranchia, suborders Aeolidida and Doridacea) inhabit the sea floors of oceans all over the world. The unattractively named sea slug comes in a fantastic array of shapes and neon-bright colors that they themselves cannot see. Fast Facts: Nudibranchs (Sea Slugs) Scientific Name: Nudibranchia, suborders Aeolidida and DoridaceaCommon Name: Sea slugBasic Animal Group: InvertebrateSize: Microscopic to 1.5 feet longWeight: Up to just over 3 poundsLifespan: A few weeks to a year  Diet:  CarnivoreHabitat: On seafloors all over the world, between 30 and 6,500 feet below the water surfacePopulation: UnknownConservation Status: Not Evaluated Description Nudibranchs are mollusks in the class Gastropoda, which includes snails, slugs, limpets, and sea hairs. Many gastropods have a shell. Nudibranchs have a shell in their larval stage, but it disappears in the adult form. Gastropods also have a foot and all young gastropods undergo a process called ​​torsion in their larval stage. In this process, the entire top of their body twists 180 degrees on their foot. This results in the placement of the gills and anus above the head, and adults that are asymmetrical in form. The word nudibranch comes from the Latin word nudus (naked) and Greek brankhia (gills), in reference to the gills or gill-like appendages which protrude from the backs of many nudibranchs. They also may have tentacles on their heads that help them smell, taste, and get around. A pair of tentacles called rhinophores on the nudibranchs head have scent receptors that allow the nudibranch to smell its food or other nudibranchs. Because the rhinophores stick out and can be a target for hungry fish, most nudibranchs have the ability to withdraw the rhinophores and hide them in a pocket in their skin if the nudibranch senses danger. Amin Benhameurlaine  / Getty Images Species There are over 3,000 species of nudibranchs, and new species are still being discovered. They range in size from microscopic to over a foot and a half long  and can weigh up to just over 3 pounds. If youve seen one nudibranch, you havent seen them all. They come in an astonishingly wide variety of colors and shapes- many have brightly colored stripes or spots and flamboyant appendages on their head and back. Some species are transparent and/or bio-luminescent, like the Phylliroe. Nudibranchs thrive in an enormous variety of underwater environments, from shallow, temperate, and tropic reefs to Antarctica and even hydrothermal vents. cbpix/Getty Images Suborders Two main suborders of nudibranchs are dorid nudibranchs (Doridacea) and aeolid nudibranchs (Aeolidida). Dorid nudibranchs, like the Limacia cockerelli, breathe through gills that are on their posterior (back) end. Aeolid nudibranchs have cerata  or finger-like appendages that cover their back. The cerata can be a variety of shapes- thread-like, club-shaped, clustered, or branched. They have multiple functions, including breathing, digestion, and defense. Habitat and Distribution Nudibranchs are found in all the worlds oceans, from cold water to warm water. You might find nudibranchs in your local tide pool, while snorkeling or diving on a tropical coral reef, or even in some of the coldest parts of the ocean or in thermal vents. They live on or near the sea floor and have been identified at depths between 30 and 6,500 feet below the ocean surface. Diet Most Nudibranchs eat using a radula, a toothed structure that they use to scrape off prey from the rocks they cling to; some suck out the prey after predigesting its tissue with selected enzymes, rather like a wasp. They are carnivorous, so that prey includes sponges, coral, anemones, hydroids, barnacles, fish eggs, sea slugs, and other nudibranchs. Nudibranchs are picky eaters- individual species or families of nudibranchs may eat only one kind of prey. Nudibranchs get their bright colors from the food they eat. These colors may be used for camouflage or to warn predators of the poison that lies within. The Spanish shawl nudibranch (Flabellina iodinea) feeds on a species of hydroid called Eudendrium ramosum, which possesses a pigment called astaxanthin that gives the nudibranch its brilliant purple, orange, and red coloration. Some nudibranchs, like the Blue Dragon, create their own food by eating coral with algae. The nudibranch absorbs the algaes chloroplasts (zooxanthellae) into the cerata, which acquire nutrients by photosynthesis using the sun to sustain the nudibranch for months. Others have evolved other ways of farming zooxanthellae, housing them in their digestive gland. Behavior The sea slugs can see light and dark, but not their own brilliant coloration, so the colors are not intended to attract mates. With their limited vision, their sense of the world is obtained through their rhinophores (on top of the head) and oral tentacles (near the mouth). Not all nudibranchs are colorful; some use defensive camouflage to match the vegetation and hide, some can change their colors to fit, some hide their bright colors only to bring them out to warn off predators. Nudibranchs move on a flat, broad muscle called a foot, which leaves a slimy trail. While most are found on the ocean floor, some can swim short distances in the water column by flexing their muscles. Some even swim upside down. Aeolid nudibranchs can use their cerata for defense. Some of their prey such as Portuguese man-of-wars have a specialized cell in their tentacles called nematocysts that contain a barbed or venomous coiled thread. Nudibranchs eat the nematocysts and store them in the nudibranchs cerata where they can be used late to sting predators. Dorid nudibranchs make their own toxins or absorb toxins them from their food and release those into the water when needed. Despite the unsavory or toxic taste they can present to their non-human predators, most nudibranchs are harmless to humans, except those like Glaucus atlanticus which consumes nematocytes and so may consider you a predator and sting. Reproduction and Offspring Nudibranchs are hermaphrodites, meaning that they have reproductive organs of both sexes. Because they cant move too far, too fast and are solitary in nature, its important for them to be able to reproduce if the situation presents itself. Having both sexes means that they can mate with any adult that happens to pass by. Nudibranchs lay masses of spiral-shaped or coiled eggs, which are for the most part left on their own. The eggs hatch into free-swimming larvae which eventually settle onto the ocean bottom as adults. Only one species of nudibranch, the Pteraeolidia ianthina, exhibits parental care by guarding the newly-laid egg masses. Nudibranchs and Humans Scientists study nudibranchs because of their complex chemical makeup and adaptations. They have rare or novel chemical compounds which possess anti-microbial and anti-parasitic traits which may aid in the fight against cancer.   Studies of nudibranch DNA also offer assistance in tracking ocean conditions relative to climate change. Threats These beautiful animals dont live very long; some live up to a year, but some only for a few weeks. The global population of nudibranchs is currently unassessed- researchers are still discovering new ones each year- but field observations such as that conducted by Endangered Species International suggest that many species are becoming rare, due to water pollution, degradation, habitat loss, and biodiversity decline associated with global warming.   Sources Bertsch, Hans.

Developing a support system to improve quality of life for erectile Research Paper

Developing a support system to improve quality of life for erectile dysfunction in prostatectomy - Research Paper Example The researcher states that one of the most inevitable aspects of the human life span is aging. What makes aging a great issue within the health community is that it brings with it numerous degenerative diseases and conditions. Some of these degenerative diseases include osteoarthritis, Amyotrophic Lateral Sclerosis (ALS), Alzheimer’s disease, atherosclerosis, rheumatoid arthritis, Huntington’s disease, heart diseases and numerous others. Sometimes, some degenerative diseases or conditions affect one gender more than the other. For example, females have to deal with menopause and all the complications such changes in the body bring about For males, one of the conditions most have to face is erectile dysfunction. Erectile dysfunction (ED) involves the inability to maintain, or even achieve, an erection that is adequate for satisfactory sexual intercourse. Although some temporary cases of erectile dysfunction have been documented in males, these can be attributed to factor s other than the degeneration of the human body. What is clinically relevant for healthcare providers as well as researchers is erectile dysfunction that involves a consistent failure to achieve and/or maintain erection which affects around half of all attempts at sexual intercourse. It is a common problem affecting men and thus impacting on the quality of life and their partners. This result into fear, loss of self esteem (self image), self confidence and depression. It has been estimated to affect more than 150 million men with only 20% of men seeking medical attention. (Aversa et al, 2004). In USA it affects between 20 to 30 million with risks of development being high with increasing age (Hellstrom et al, 2002). Numerous reasons have been provided for erectile dysfunction, including both psychological and physical factors. Psychological causes may involve stress, depression, relationship changes, low self-esteem, fatigue, performance anxiety, and numerous others (Ignatavicius & Workman, 2006). Although psychological causes are sometimes more common in temporary cases of erectile dysfunction, these factors can aggravate the dysfunction brought about by physical causes, especially among older males. On the other hand, physical reasons for erectile dysfunction include diminished testosterone levels, thyroid dysfunction, hyperprolactinemia, cardiovascular diseases, endocrine problems, and even the decrease in penile response to nitric oxide, the neurotransmitter responsible for the erection of the penis (LeMone, Burke, & Bauldoff, 2011). Another well-documented reason attributed to erectile dysfunction is prostatectomy. Prostatectomy involves the removal or resection of a portion of a prostate due to enlargement of the prostate or one of its lobes (Brunner, Smeltzer & Bare, 2010). Studies have established that one of the expected complications of prostatectomy, specifically radical prostatectomy, is erectile dysfunction. Such a complication is most attributed to the damage caused on nerves during the surgery involving the resection of the prostate. These damages can be attributed to actual physical trauma on the nerves involving penile erection, or to complications from the anesthetic used (Lewis, et al., 2011). Still, it must be acknowledged that almost all forms of prostatectomy, even those that aim to spare the nerves (i.e. laparoscopic and robot-assisted prostatectomy), lead to erectile dysfunction, although to varying degrees (Zippe, Nandipati, Agarwal, & Raina, 2006). Identifying problems The identified problems are lack of knowledge about the option treatments, emotional distress anxiety about performance, dissatisfaction, impaired self esteem which affect personal relationships, lack of support and understanding from other significant, spousal dissatisfaction and quality of life affected (Aversa et al, 200

Cancer Spotting Googles by Dr. Samuel Achilefu Essay

Cancer Spotting Googles by Dr. Samuel Achilefu - Essay Example He has helped in creating over 41 US issued patents that mainly relate to applications of imaging and he has authored many scientific publications. With his knowledge in different molecular imaging aspects and experiences in both industry and academia, Dr. Achilefu has offered a different aspect to the management of the Molecular Imaging centers excellence. With this overview, this article will centralize on the profile of Dr. Samuel Achilefu, and touch on the role he has played in applying change strategies that have introduced positive change in the medical field especially with the Cancer Spotting Goggles. Dr. Samuel Achilefu grew up in Ida, Nigeria. While he was still a child, his parents advised him that it was only through the pursuit of a higher education that he could possibly be able to make any visible impact on the world. Since his childhood he was attracted towards the more practical aspects of science, mainly how things worked. For a while, he actually believed that solving equations could actually address all the global problems. However, it was not until he studied biology and chemistry while in college that he realized that to have a chance of actually helping people, it was necessary for him to enter the laboratory. Currently, Dr. Achilefu manages a team of 35 researchers in his laboratory that are mainly devoted to extending the optical imaging boundaries to address the needs of molecular medicine in the current world. The broad definition of optical imaging can be described as the usage of light to be able to visualize an object. A simple microscope often used in laboratories in high school classes is an example of this optical imaging technique. The modern digital imaging system is also another example since it can detect a single molecule or cell that is within the cells. Even with the extensive availability of non-optical techniques like the magnetic resonance imaging (MRI), computed
