Communication Mechanism System

Communication Mechanism System Explain the importance of intercellular communication and describe the mechanism involved. Intercellular communication is important because it assist the nervous system to elongate the long-term process as growth, development, or reproduction. The endocrine system uses chemical messengers to relay information and instructions between cells. One of the mechanisms involved in intercellular communication is know as direct communication this communication is rare but is important when it occurs. This is when two cells of the same type and the cells must be in extensive physical contact. The cells are so close they function as one. The majority of the communication is known as paracrine communication which is where the cell continuously exchange chemical messages between each other so they in sink with one another. Compare and contrast the modes of intercellular communication used by the endocrine and nervous systems and discuss the functional significance of the differences between the two systems. The nervous system performs short term â€Å"crisis management† and the endocrine system regulates long-term, ongoing metabolic processes. The endocrine system uses endocrine communication which helps regulate hormones through the circulatory system and the nervous system dose not have the capability to do this. Another significant difference is synaptic communication the nervous system uses this form of communication of neurons to release neurotransmitter at a synapse very close to a target cell that bear the right receptors. This form of communication allows the body to react quickly to situations to escape from harm. 3. Explain the general mechanisms of hormonal action and identify which hormone types work through each mechanisms. A hormone receptor is a protein molecule to which a particular molecule binds strongly. Each cell has receptors for responding to several different hormones, but cells in different tissues have different combinations of receptors. For every cell, the presence or absence of a specific receptor determines the cells hormonal sensitivities. Hormone receptors are located either on the cell membrane or inside the cell. The mechanisms of hormonal action are that receptors for catecholamines, peptide hormones, and eicosanoids are in the cell membrane of target cells, Thyroid and steroid hormones cross the cell membrane and bind to receptors in the cytoplasm or nucleus, activating or inactivating specific genes. 4. Describe the control of endocrine organs. The endocrine organs are controlled by three mechanisms of the hypothalamic control. One is the secretion of regulatory hormones to control activity of anterior lobe of pituitary gland. Two the production of ADH and oxytocin. And finally is the control of sympathetic output to adrenal medullae. Explain the structural and functional relationship between the pituitary gland and the hypothalamus. The pituitary gland releases nine important peptide hormones; all bind to membrane receptors and use cyclic-AMP as a second messenger. The pituitary gland hangs inferior to the hypothalamus which all the anterior lobe of the pituitary gland to help in the function of the hypophyseal portal system. By the hypothalamus secreting specific regulatory hormones it controls the production of hormones in the anterior lobe. This whole system works to secret hormones from the hypothalamus through the pituitary gland in a network of capillaries that are connected. All this ensures that all the hypothalamic hormones entering the portal vessels will reach the target cells in the anterior lobe of the pituitary gland before entering general circulation. 6. Predict how alternations in hormone production, delivery, or reception by target tissues would affect its action and blood concentration levels. Describe the factors that could determine a cells hormonal sensitivity. Cells sensitivity is determined by two factors down-regulation and up-regulation. Down regulation is a process in which the presence of a hormone triggers a decrease in the number of hormone receptors. This process is when levels of particular hormones are high, cells become less sensitive to it. Up-regulation is a process in which the absence of a hormone triggers an increase in the number of hormone receptors. In this process the levels of a particular hormone are low, cells become more sensitive to it. Identify the hormones produced by the anterior and posterior lobes of the pituitary gland and specify the functions of those hormones. The anterior lobe produces seven hormones: Thyroid-stimulating hormone (TSH) targets the thyroid gland and triggers the release of thyroid hormones. As circulation concentrations of thyroid hormones rise, the rate of TRH and TSH production decline. Adrenocorticotropic hormone (ACTH) stimulates the release of steroid hormones by the adrenal cortex and targets cells that produce glucocorticoids. Gonadotropins regulate the activities of the gonads. Follicle-stimulating hormone (FSH) promotes follicle development in females and, in combination with luteinizing hormone, stimulates the secretion if estrogen by ovarian cells. In males, FSH stimulates sustentacular cells, specialized cells in the tubules where sperm differentiate. Luteinizing hormone (LH) induces ovulation, the production of reproductive cell in females. Also promotes the secretion, by the ovaries, of estrogen and the progestin, which prepare the body for pregnancy. In male hormone is sometimes called interstitial cell-stimulating hormone (ICSH), because it stimulates the production of sex hormones by the interstitial cells of the testes. Prolactin (PRL) works with other hormones to stimulate mammary gland development. Growth hormone (GH) stimulates cell growth and replication by accelerating the rate of protein synthesis. The posterior lobe produces two hormones: Antidiuretic hormone (ADH) is released in response to a variety of stimuli, most notably a rise in the solute concentration in the blood or a fall in blood volume or blood pressure. A rise in the solute concentration stimulates specialized hypothalamic neurons. Oxytocin (OT) stimulates smooth muscles contraction in the wall of the uterus, promoting labor and delivery. After delivery this hormones stimulates the contraction of myoepithelial cells around the secretory alveoli and the ducts of the mammary gland, promoting the ejection of milk. Discussion the results of abnormal levels of pituitary hormones Abnormal levels of pituitary hormones can have a cast and complex impact on the growth, fertility, and function on the human body via the effect of the hormones on their target organs. Diseases anywhere from asthma to growth problems can occur. Identify the hormones produced by the thyroid gland, specify the functions of those hormones, and discuss the causes and results of abnormal levels of thyroid hormones. The thyroid gland produces thyroglobulin, tyrosine, and thyroxine. The functions of these hormones are: Thyroid hormones enter target cells by means of an energy dependent transport system and they affect almost every cell in the body. Thyroid hormones bound to cytoplasmic receptors are held in storage until intracellular levels of thyroid hormone decline. Thyroid hormones bound to mitochondria increase ATP production. Thyroid hormones bound to receptors in the nucleus activates genes that control energy utilization. The calorigenic effect: the cell consumes more energy resulting in increased heat generation. In growing children, thyroid hormones are essential to normal development of the skeletal, muscular, and nervous systems. The thyroid gland is primarily responsible for a strong, immediate, and short-lived increase in the rate of cellular metabolism. The major factor controlling the rate of thyroid hormone release is the concentration of TSH in the circulating blood. The causes of abnormal levels of thyroid hormones can create an iodide deficiency because in the U.S. we consume more than they daily amount needed. Thyroid hormone production declines, regardless of the circulating levels of TSH. Describe the functions of the parathyroid hormones, and the effects of abnormal functions of each hormone. Parathyroid hormone has four major effects: 1. It stimulates osteoclasts, accelerating mineral turnover and the release of Ca2+ from bone. 2. It inhibits osteoblasts, reducing the rate of calcium deposition in bone. 3. It enhances the reabsorption of Ca2+ at the kidneys, reducing urinary losses. 4. It stimulates the formation and secretion of calcitriol at the kidneys. The effects of calcitriol complement or enhance those of PTH, but one major effect of calcitriol is the enhancement of Ca2+ and PO43- absorption by the digestive tract. The parathyroid glands, aided by calcitriol, are the primary regulators of blood calcium I levels in healthy adults. When the parathyroid calcium levels become abnormal there are two disorders that can occur. Hypoparathyroidism the gland secretes low calcium concentrations in body fluid. Hyperparathyroidism is when calcium concentrations become abnormally high. Identify the hormones produced by the adrenal cortex and medulla and specify the functions of each hormone The adrenal cortex secrets the hormones adrenocortical, mineralocorticoids, glucocorticoids, and androgens. The adrenocortical steroids or corticosteroids are vital: if the adrenal glands are destroyed or removed, the individual will die unless corticosteroids are administered. Mineralocorticoids increase renal reabsorption of Na+ and water which accelerates urinary loss of potassium. Glucocorticoids release amino acids from skeletal muscles and lipids from adipose tissue; promote liver formation of glucose and glycogen; promotes peripheral utilization of lipids; anti-inflammatory effects. Androgens are not important in men; encourages bone growth, muscle growth, and blood formation in children and women. The adrenal medulla secrets epinephrine and norepinephrine. These hormones increase cardiac activity, blood pressure, glycogen breakdown, blood glucose levels; releases lipids by adipose tissue. Also this is where the fight or flight syndrome is sparked. Discuss the results of abnormal levels of adrenal hormone production When the adrenal hormone becomes abnormal it produces several different disorders. The first is hypoaldosteronism; the zona glomerulosa fails to produce enough aldosterone, generally either as an early sign of adrenal insufficiency or because the kidneys are not releasing adequate amounts of rein. A rare but serious disorder can occur called Addisons disease which results from inadequate stimulations of the zona fasciculata by the pituitary hormone ACTH or, more commonly, from the inability of the adrenal cells to synthesize the necessary hormones, generally from adrenal cell loss caused by autoimmune problems. Another disease is Cushings disease which results from overproduction of glucocorticoids. There is another aspect of abnormal production of adrenal hormones that affects men and womens sexual characteristics called adrenogenital syndrome. In women, this condition leads to the gradual development of male secondary sex characteristics, including body and facial hair patters. In male to causes an increase of estrogen resulting in larger breast tissue or other female secondary sex characteristics. Last but not least there is a disorder of the adrenal medulla called pheochromocytoma which is an overproduction of epinephrine that causes a tumor that produces catecholamines in massive quantities. Describe the functions of the hormones produced by the pineal gland. It contains pinealocytes, which synthesize the hormone melatonin. The suggested functions of the pineal gland is that it inhibits reproductive functions, protects against damage by free radicals, and sets circadian rhythms. Identify the hormones produced by the pancreas and specify the functions of those hormones. The pancreas contains both exocrine and endocrine cells. Cells of the endocrine pancreas form clusters called pancreatic islets (islets of Langerhans). The pancreatic islets release insulin and glucagons. Insulin is released when blood glucose levels rise, and it stimulates glucose transport into, and utilization by, peripheral tissues. Glucagon is released when blood glucose levels decline, and it stimulates glycogen breakdown, glucose synthesis, and fatty acid release. Discuss the results of abnormal levels of pancreatic hormone production. When the pancreatic hormones produce abnormal levels of insulin and glucose it causes an individual to be diabetic. Diabetes mellitus is characterized by glucose concentration that is high enough to overwhelm the reabsorption capabilities of the kidneys. Glucose appears in the urine, and urine production generally becomes excessive. Describe the functions of the hormones produced by the kidneys, heart, thymus, testes, ovaries, and adipose tissue. Control of the heart, kidneys, thymus, gonads, and adipose tissue. The kidneys release erythropoietin and calcitriol into the red bone marrow, intestinal lining, bone and kidneys. All of the hormones releases are to stimulate red blood cell production and calcium and phosphate absorption and it also stimulates calcium ions from bone; inhibits PTH secretion. The heart controls the hormones natriuretic that targets the kidneys, hypothalamus, and adrenal gland. These hormones increase water and salt loss at kidneys; decrease thirst; and suppress secretion of ADH and aldosterone. The adipose tissue contain two hormones that support to different functions, first is leptin which targets the hypothalamus for suppression of appetite; permissive effects on GnRH and gonadotropin synthesis. Second is resistin that targets cell throughout the body that suppresses insulin response. Last but not least are the gonads with the hormones androgens, inhibin, estrogen and progestin. All these hormones a re targeted by the pituitary glands to support the reproductive organs in males and females. In males the interstitial cells of the testes produce androgens. Testosterone is the most important sex hormone in males. Sustentacular cells in the testes support the differentiation and physical maturation of sperm. Under FSH stimulation, these cells secrete the hormone inhibin, which inhibits the secretion of FSH at the anterior lobe. The female body develops oocytes in the follicles; follicle cells produce estrogens, especially estradiol. After ovulation, the remaining follicle cells reorganize into a corpus luteum. Those cells release a mixture of estrogens and progestins, especially progesterone. Explain how hormones interact to produce coordinated physiological responses. Hormones interact to produce coordinated physiological responses in four ways: 1. antagonistic (opposing) effects 2. synergistic (additive) effects 3. permissive effects, in which one hormone is necessary for another to produce its effect 4. integrative effects, in which hormones produce different, but complementary, results Identify the hormones that are especially important to normal growth, and discuss their roles. Several hormones are especially important: GH, thyroid hormones, insulin, PTH, calcitriol and reproductive hormones. The circulation concentrations of these hormones are regulated independently. Changes produce unique individual growth patterns. Growth Hormone (GH): effects are most apparent in children where GH supports muscular and skeletal development. In adults GH assists in the maintenance of normal blood glucose concentrations and in the mobilization of lipid reserves. Thyroid hormones: if these hormones are absent during fetal development or for the first year after birth, the nervous system will fail to develop normally and mental retardation will result. If T4 concentrations decline before puberty, normal skeletal development will not continue. Insulin: without insulin the passage of glucose and amino acids across cell membranes will be drastically reduced or eliminated. Parathyroid Hormone (PTH) and Calcitriol: promote the absorption of calcium salts for subsequent deposition in bone. Without adequate levels of both hormones, bones will be weak and flexible. Reproductive Hormones: the sex hormones (androgens in males, estrogens in females) stimulate cell growth and differentiation in their target tissues. Differential growth induced by each hormone accounts for gender-related differences in skeletal proportions and secondary sex characteristics. Define the general adaptation syndrome. Any condition that threatens homeostasis is a stress. Our bodies respond to a variety of stress-causing factors through the general adaptation syndrome (GAS), or stress response. The GAS can be divided into three phases: 1. the alarm phase 2. the resistance phase 3. the exhaustion phase http://www.harford.edu/faculty/SSchaeffer/Endocrine%20Outline.doc http://www.miramar.sdccd.cc.ca.us/faculty/kpetti/Bio160/Martini7DetailLectOutlines/18-Detailed_Lect_Out_LO.pdf.pdf

A Career in Electrical Engineering Essays -- Papers

A Career in Electrical Engineering Choosing the right career can mean the difference between being satisfied and being disappointed with my life. Many factors can influence the career that I may have for the rest of my life. A decision that I am going to make at the young age of nineteen will have a major impact on the next ten years if not the rest of my life. In order to make the best decision possible for my future I have decided, if not forced, to research a career of interest to me. The two major career choices I have been interested in for the past few years have been engineering and teaching. I have already done researched teaching so I decided to research engineering. There are many different types of engineering so I decided to pick the one most interesting to me. Electrical engineering is the career field I have selected to investigate. Engineering is something my parents have urged me to consider. Since a young kid I have been interested in building things. I use to tell my parents I wanted to be an inventor and build a time machine. Legos were my favorite toy growing up, and I have always been exceptionally good in math. Since my freshmen year in high school I have been interested in becoming a teacher, but during my freshmen year in college I was becoming more and more aware of the amount of money lower level teachers made. Many people were recommending engineering as a possible career option so I decided to look into it. Since I have always found electricity to be cool I decided to learn more about electrical engineering as a future career field. The Dictionary of Occupational Titles code for electrical engineering is 003.061-010, while the Guide for Occupational Exploration code is 05.01.01. There is anot... ... edge as an electrical engineer or whatever occupation I choose to enter. I feel very satisfied with the information I obtained. At times I was bored in this class being the only male, and having to listen to a bunch of females whine over stuff I didn’t care about. With regards to electrical engineering I leaned that electrical engineering is boring, and does not seem like an occupation I would enjoy. The people I talked to about engineering were happy with their jobs but were also nerds. I think I should really consider teaching as a possible career choice. Therefore, I am not certain about the career choices I have made. I think I will try to major in math and become a math teacher; I can always change my major if I am not happy with how things are going. I have learned that my happiness will be increased with better career satisfaction versus monetary gain.

How Does Technology Influence the Google Generation

Nowadays, with the advancement of technology, our current generation, the so-called â€Å"Google generation†, is being influenced in a negative way. So what is the actual meaning of â€Å"Google generation†? One of the common definitions is that â€Å"The â€Å"Google generation† is a popular phrase that refers to a generation of young people, born after 1993, growing up in a world dominated by the Internet† (Rowlands et al. 292). However, that definition is not definitely precise. Jim Ashling says, â€Å"Everyone is members of the Google generation. All age groups exhibit some Google-generation traits† (22). Thus, the Google generation encompasses not only the young, but also the other generations. Which one creates the Google generation? The answer is technology. Since it is inherent in every area of life, the Google generation is impacted by it, which consists of changing their behaviors, affecting their critical thinking, swaying their reading habit, and making the children digital-age. The internet is currently considered an integral part of the society. It provides both advantages and disadvantages. For one thing, the information literacy of young people has not been improved with the widening access to technology (Rowlands et al. 95). Further, Internet research shows that the speed of young people's web searching means that little time is spent in evaluating information, either for relevance, accuracy or authority (Rowlands et al. 295). This will make them more work-shy. In addition, young people have a poor understanding of their information needs and thus find it difficult to develop effective search strategies (Rowlands et al. 295). As a result, they exhibit a strong preference for expressing themselves in natural language rather than analyzing which key words might be more effective (Rowlands et al. 295). Moreover, young people have unsophisticated mental maps of what the internet is, often failing to appreciate that it is a collection of networked resources from different providers (Rowlands et al. 296). Consequently, the search engine, Yahoo or Google, becomes the primary brands that they associate with the internet (Rowlands et al. 296). Therefore, their ability of evaluating and searching information will principally count on the search tools, and their creativity will be restricted. In the other words, it can be considered a type of artificial literacy. When they receive information of a specific topic, they think that they understand it. However, no one recognizes that information is extracted from technology, especially the internet, not from their authentic perceptions. â€Å"Critical thinking as an attitude is embedded in Western culture. There is a belief that argument is the way to finding truth,† observes Adrian West, research director at the Edward de Bono Foundation U. K. , and a former computer science lecturer at the University of Manchester (Greengard 18). Thereby, critical thinking is very crucial in speculating the information. If one loses that ability, he cannot perceive the entity of issues. Unfortunately, currently rapid development of technology causes their thinking process to be passive. They are not able to think the way which was formerly. In contrast, their present thinking process may be called machinery sense. Greengard states about this issue: Although there is little debate that computer technology complements and often enhances the human mind in the quest to store information and process an ever-growing tangle of bits and bytes, there is increasing concern that the same technology is changing the way we approach complex problems and conundrums, and making it more difficult to really think (18). Additionally, the wealth of communications and information can easily overwhelm our reasoning abilities (Greengard 18). Accordingly, Bugeja concludes â€Å"Without critical thinking, we create trivia† (Greengard 19). Seriously, it is time to take a closer and more serious look at technology and understand the subtleties of how it affects the thinking process. What’s more, their reading habit is one of technology’s considerable victims. According to the National Endowment for the Arts, literary reading declined 10 percentage points from 1982 to 2002 and the rate of decline is accelerating (Greengard 18). That is an authentically alarming statistic. Along with a diversity of information on the internet, their reading habit has been lessened drastically. The reason is that previously, people only collected information through books, which are the chief source. They regularly read almost all pages of a book. Notwithstanding, the technology distraction level is accelerating to the point where thinking deeply is difficult (Greengard 18). They are overwhelmed by a constant barrage of devices and tasks, and increasingly suffer from the Google syndrome (Greengard 18). People accept what they read and believe what they see online is fact when it is not (Greengard 18). Nicholas Carr, a journalist, told that it used to be easy to immerse himself in a book or a lengthy article. Nonetheless, the Net distracted his concentration on reading. He has to struggle against his reading habit that used to come naturally. For more than a decade now, he has been spending most of time online, searching, and surfing on the internet. As a result, the Net seems to chip away his capacity for concentration and contemplation. It is not only Nicholas’s problem, but is ours as well. The authors of the study report say: It is clear that users are not reading online in the traditional sense; indeed there are signs that new forms of â€Å"reading† are emerging as users â€Å"power browse† horizontally through titles, contents pages and abstracts going for quick wins. It almost seems that they go online to avoid reading in the traditional sense. (Carr, par. ) Also, he supposes that the Google generation comes to rely on computers to mediate their understanding of the world; it is their own intelligence that flattens into artificial intelligence (Carr, par. 36). At any rate, they are able to absorb the benefits of reading through the internet and keep the traditional habits because reading is learning and entertaining. The most striking example of the Google generation is the â€Å"digital-age† kids (O’Brien, par. 1). Why are they called â€Å"digital-age†? O’Brien has a 15-year-old son whose study is completely distracted by the technology. She had to keep a deep eye on him whenever he took an exam. She says â€Å"Every time I crossed the threshold, the scene was the same: textbooks remained firmly closed in his bag while the laptop was open on his desk. On the screen was some history/ physics/English document, but also his Facebook and iTunes pages. In his ears were the iPod plugs, playing back a podcast. And sometimes, just to fracture his concentration even further, he might have had a half-played video running on YouTube as well† (O’Brien, par. 3 and 4). She was irritated to keep his son on concentrating. From her problem, she concludes â€Å"He’s a digital native; you’re a digital immigrant† (O’Brien, par. 6). Digital natives and digital immigrants are terms named by the American futurist, Marc Prensky, to distinguish between those who have grown up with technology and those who have adapted to it (O’Brien, par. 7). According to researchers, the children are in the midst of a sea change in the way that they read and think (O’Brien, par. 8). They have wonderfully flexible minds. Further, they absorb information quickly, adapt to changes and are adept at culling from multiple sources. But they are also suffering from internet-induced attention deficit disorder (O’Brien, par. 8). Rose Luckin, Professor of Learner- Centred Design at the London Knowledge Lab and a visiting professor at the University of Sussex, is working on a study examining the internet's impact on pupils' critical and meta-cognitive skills. â€Å"The worrying view coming through is that students are lacking in reflective awareness,† she says. â€Å"Technology makes it easy for them to collate information, but not to analyze and understand it† (O’Brien, par. ). In short, it is time the society should do something to improve the digital-age children. Therefore, the role of parents and teachers are constantly respected and highly valued, like Rose Luckin says: Because they have been using digital technology all their lives, our children feel they have authority over it. But technology cannot teach them to reflect upon and evaluate the information they are gathering online. For that, the role of teachers and parents remains fundamentally important. (O’Brien, par. 2) Even though technology brings many various utilities to the civilization of the society, there are some issues on which are scouted out seriously. The Google generation ought to be aware of how to harness it. Do not let it affect the behavior, the ability of thinking critically, reading habit, and â€Å"digital-age† children. At any events, they should utilize the best benefits of technology to improve the life in a proper way. Keep in mind that technology can be a good servant, but it can be also a bad boss.

Prejudice, Stereotypes, and Discrimination essayEssay Writing Service

Prejudice, Stereotypes, and Discrimination essayEssay Writing Service Prejudice, Stereotypes, and Discrimination essay Prejudice, Stereotypes, and Discrimination essayThe regulation of individuals’ social behavior is carried out through the system of individual attitudes. The forms of attitudes, stable and closed from the influence of new experience, are presented by stereotypes and prejudices. Their cognitive component contains distorted, irrational, absurd knowledge about objects that do not meet the changing reality. With respect to inanimate objects this refers, for example, to all sorts of superstitions, but in the social sphere, stereotypes and prejudices widely serve as the justification of racial, ethnic, class and economic differences. The significance of prejudices and stereotypes as an illusory, fantastic explanation of reality consists in the fact that they indirectly contribute to the preservation of social inequality and inhibit progressive change.  Prejudice and stereotypes as illusionStereotypes mean extremely stable and limited understanding of a social object or situation b y which people are guided in their behavior without a second thought (Myers, 2012; Feenstra, 2013). A major role in the structure of a stereotype belongs to its emotional charge, which clearly indicates to what is acceptable and unacceptable in relation to any object. Thus, if an object of a stereotype is another person, the major features are often one’s gender, nationality, or profession, while other differences may be unduly ignored. According to Inzlicht and Schmader (2011), the specificity of this approach lies in the unconscious division of people into â€Å"us† and â€Å"them† with ingroup experiences perceived as idealized and endowed with pculiarities in a positive way (autostereotype), while outgroups are endowed with negative assessments (heterostereotype). As a result, stereotypes form a simplified and highly superficial understanding of the social reality phenomena.In its turn, the concept of prejudice includes irrational components of social and in dividual consciousness, based on the inaccurate, distorted, stereotypized knowledge that was accepted uncritically, with the negative emotional manifestations becoming intense (Myers, 2012; Feenstra, 2013). A person with a prejudice may not like those who are different and discriminate against them by one’s actions. Thus, while prejudice is a negative attitude, discrimination is a negative behavior. In general, basing on Myers (2012) and Inzlicht and Schmader (2011) studies, negative assessments as a measure of prejudice may be linked to the emotional associations, need to justify one’s discriminatory behavior or stable negative beliefs, i.e. stereotypes.Prejudices and stereotypes have several sources as they perform several functions. In particular, they can express a sense of one’s Self and the desire to seek affectation from the society; defend self-concept from anxiety caused by uncertainty about one’s own safety or internal conflict; as well as suppo rt group interests, values, and social status. Given the latter, in our opinion, one of the most important origins of prejudice and stereotypes is social inequality. It is difficult, for example, to disagree with Inzlicht and Schmader (2011) that stereotypical views about African Americans and women help to justify the lower social status of these groups. Indeed, prejudices basically help justify the economic and social superiority of those with wealth and power. Meanwhile, attitudes can easily match the social hierarchy not only because they justify it, but also because occurring discrimination affects those who become its victims, and so the social beliefs can turn into self-fulfilling prophecies, as Myers (2012) and Feenstra (2013) argue.In addition, identifying ourselves with certain groups, we include social identification into the personal one (i.e. a sense of personal qualities and attitudes). As Myers (2012) marks, categorizing people into groups, we thus contrast our group to other groups (â€Å"they†) with a clear predisposition and manifestation of favoritism for our own groups. As a result, a sense of belonging (â€Å"we†-feeling) increases our self-concept and helps to achieve inner peace. We are looking for not only self-esteem, but also opportunities to be proud of our group. Moreover, the fact that we perceive our groups as different in the better way from the others contributes to the situation where we also tend to see ourselves in a more attractive light (Myers, 2012; Feenstra, 2013). On this basis, stereotypes successfully fix in the public mind, and conformism here plays an important role. Indeed, the shaped prejudices are kept up mainly by inertia, as Feenstra (2013) reasonably notes. If a prejudice is accepted by the society, the majority will prefer to take the path of least and will promote stereotypes not so much because of the need to hate someone as because of the desire to be accepted and valued by this society.In its essence, the underlying cause of stereotypes’ adoption is a non-developed cognitive component (Myers, 2012; Inzlicht Schmader, 2011). In particular, explaining the actions of others, an individual often makes a fundamental attribution error: being inclined to attribute the behavior of people to their internal dispositions, one does not consider important situational forces (Feenstra, 2013). In addition, as Myers (2012) puts this, it is an attribution error that makes an individual biased in the interpretation of one’s own group members’ behavior as positive, whereas positive actions committed by the members of an out-group are usually not taken into account. In general, we sometimes make judgments or start communicating with someone having nothing but a stereotype at hand. In such cases, stereotypes and prejudice are able to fully deprive of objectivity and distort the interpretation and memories of people and environment.  ConclusionThe modern view of preju dice arising due to the recent studies leads us to an idea of how stereotypical thinking becomes a byproduct of information processing – a method individuals apply to simplify the perception of the world. However, the emergence of illusive relationships between the belonging to a certain social group and one’s behavior has both cognitive sources and cognitive consequences. Directing our interpretation and our memories, stereotypical thinking results in the fact that we find evidence in its favor, even where such evidence is not present at all. Therefore, stereotypes are resilient and difficult to modify. And yet, there are some reserve methods that can weaken them. Thus, if status inequality creates prejudice, the society should strive to create relationships where cooperation and social equality will dominate. In particular, if we know that some type of discrimination is based on prejudice, we need to get rid of discrimination, but depriving it of any institutional su pport. Generally, it is believed that the psychological and social health of a person is based on awareness of both one’s own individuality and uniqueness and group identity, as well as one’s belonging to all humanity.

Popovich, his father, Philip II of Macedon, was a brilliant ruler and strategist. His mother was Olympias, princess of Epirus, daughter of King Neoptolemus. Olympias was initiated into the cults of Dionysus and Orpheus. She was often jealous, vindictive and very protective of Alexander.Popovich describes the boy Alexander as, “fearless and strong.

Along lines of Process and emotional struggle with ADHD in the Family - Research Paper Example It is because of the abnormal function of the brain that certain disorders are seen in the human beings.Attention Deficit Hyperactivity Disorder is an example of such a disorder which diminishes the normal functions of the brain. Initially it was thought that ADHD only occurred in adults but it has been found that this condition also affects adults. This essay would revolve around the perspectives of ADHD and as to how it affects the children. ADHD is a neuropsychiatric condition which is characterized by lack of attention or concentration for a long period of time. It is because of this characteristic that the persons suffering from ADHD have difficulty in carrying out their daily life activities.This essay would revolve around the diagnosis of ADHD along with the treatment and other related issues of ADHD (Grosenbach 2000 & Whiteman et al 1995).Historical Context In order to understand the basics of ADHD it is necessary that it is studied in its historical context. ADHD was first d iscovered in the early eighteenth century by George Still. The name given to the disorder has changed ever since its discovery.George Still conducted a research to find out that 20 children were suffering from the problem of attention deficiency. It was here that he put forward a theory regarding these children that they may be suffering from a genetic problem.George Still named the disorder as the Defect of Moral Thought.... In 1970s more symptoms were associated with the disorder and this formed a complete spectrum for the disorder. It was in 1980s that the name Adult Deficiency Disorder came into being and was included in the Diagnostic and Statistic Manual III of American Psychiatric Association.

The sign s and symptoms laid down by ICD and DSM IV are then compared to see if the child is suffering from the problems laid down in it or not (Berger 2008). The sign and symptoms of ADHD are anxiety, irritability, lack of concentration and difficulty in completing organized tasks. The child suffering from ADHD has difficulties in taking his own decision and seeks the help of others in completing the tasks in his life (Whiteman et al 1995; Grosenbach 2000). Bipolar Disorder should be diagnosed properly as at times it gets difficult to differentiate between certain disorders and bipolar disorders.
