Immune System - the Bodys Natural Defense Mechanism

Immune System - the Body's Natural Defense Mechanism Immune System Function Theres a mantra in organized sports that says, defense is king! In todays world, with germs lurking around every corner, it pays to have a strong defense. The immune system is the bodys natural defense mechanism. The function of this system is to prevent or reduce the occurrence of infection. This is accomplished through the coordinated function of the bodys immune cells. Cells of the immune system, known as  white blood cells,  are found in our bone marrow, lymph nodes, spleen, thymus, tonsils, and in the liver of embryos. When microorganisms, such as bacteria or viruses invade the body, non-specific defense mechanisms provide the first line of defense. Key Takeaways The immune system is the bodys natural defense mechanism whose function is to help fight infections.The innate immune system is a non-specific response that includes deterrents like the skin, enzymes in saliva, and inflammatory reactions by immune cells.If organisms get past the innate immune system, the adaptive immune system is the backup system. This backup system is a specific response to specific pathogens.The adaptive immunity system has two primary components: a humoral immune response and a cell mediated immune response.Disorders and diseases that can result from a compromised immune system include: allergies, HIV/AIDS and rheumatoid arthritis. Innate Immune System The innate immune system is a non-specific response that includes primary deterrents. These deterrents ensure protection against numerous germs and parasitic pathogens (fungi, nematodes, etc.). There are physical deterrents (skin and nasal hairs), chemical deterrents (enzymes found in perspiration and saliva), and inflammatory reactions (initiated by immune cells). These particular mechanisms are named appropriately because their responses are not specific to any particular pathogen. Think of these as a perimeter alarm system in a house. No matter who trips the motion detectors, the alarm will sound. White blood cells involved in the innate immune response include macrophages, dendritic cells, and granulocytes (neutrophils, eosinophils, and basophils). These cells respond immediately to threats and are also involved in the activation of adaptive immune cells. Adaptive Immune System In cases where microorganisms get through the primary deterrents, there is a backup system called the adaptive immune system. This system is a specific defense mechanism in which immune cells respond to specific pathogens and also provide protective immunity. Like innate immunity, adaptive immunity includes two components: a humoral immune response and a cell mediated immune response. Humoral Immunity The humoral immune response or antibody†mediated response  protects against bacteria and viruses present in the fluids of the body. This system uses white blood cells called B cells, which have the ability to recognize organisms that dont belong to the body. In other words, if this isnt your house, get out! Intruders are referred to as antigens. B cell lymphocytes produce antibodies that recognize and bind to a specific antigen to identify it as an invader that needs to be terminated. Cell Mediated Immunity The cell mediated immune response protects against foreign organisms that have managed to infect body cells. It also protects the body from itself by controlling cancerous cells. White blood cells involved in cell mediated immunity include macrophages, natural killer (NK) cells, and T cell lymphocytes. Unlike B cells, T cells are actively involved with the disposal of antigens. They make proteins called T cell receptors that help them recognize a specific antigen. There are three classes of T cells that play specific roles in the destruction of antigens: Cytotoxic T cells (which directly terminate antigens), Helper T cells (which precipitate the production of antibodies by B cells), and Regulatory T cells (which suppress the response of B cells and other T cells). Immune Disorders There are serious consequences when the immune system is compromised. Three known immune disorders are allergies, severe combined immunodeficiency (T and B cells are not present or functional), and HIV/AIDS (severe decrease in the number of Helper T cells). In cases involving autoimmune disease, the immune system attacks the bodys own normal tissues and cells. Examples of autoimmune disorders include multiple sclerosis (affects the central nervous system), rheumatoid arthritis (affects joints and tissues), and graves disease (affects the thyroid gland). Lymphatic System The lymphatic system is a component of the immune system that is responsible for the development and circulation of immune cells, specifically lymphocytes. Immune cells are produced in bone marrow. Certain types of lymphocytes migrate from bone marrow to lymphatic organs, such as the spleen and thymus, to mature into fully functioning lymphocytes. Lymphatic structures filter blood and lymph of microorganisms, cellular debris, and waste.

generation X essays

generation X essays People think that generation X today does nothing but complains about everything and it is so apathetic. Consequently, we can realize that it is a generation that is completely different from the prior generation. Karl Zinsmeister, the writer of The Humble Generation , states that some people believe that Xers are materialistic, inconsiderate and unprogressive. The author also states that liberals accuse them of lacking exemplars. Generation X possesses different major characteristics which are very common nowadays. Generation X students experience different adversary emotive problems, such as eating disorders and depression. Xers believe that drastic slenderness implies that one is of a high social class. Kristi Lockhart Keil, the author of An Intimate Profile of Generation X , points out that, this career-minded generation seems to think that women with full hips and breasts are less intelligence and likely to succeed . Accordingly, we can perceive that generation X students tend to be slight in order to gain discipline and intelligence. Moreover, generation X students suffer from depression. In fact, there are various significant factors that cause their depression, and the most important one is being disregarded. Keil states that neglect increases their depression, and they get less attention from their parents; therefore, they will most often have superficial relationships with others. Xers do not want to be managed by others. As a matter of fact, they dont want someone looking over their shoulder. Perhaps as a result of their latchkey childhood, they are not used to being supervised and they are good at working on their own. It is very important to Xers to be seen as liberated and self-starters (Losyk). Therefore, Xers should be managed by teaching them things and be aware of their need for feedback. In addition, Xers adjust their ...

Dell Inc Paper Essay Example | Topics and Well Written Essays - 750 words

Dell Inc Paper - Essay Example In addition, the third party integration cost is higher than the cost of integration done by contract manufacturers. The US labors costs are higher than that of China. From the figure 6-4, it is obvious that in L5 the chassis (without motherboard) is shipped to the United States first, and subsequently the motherboards are airfreighted to the country (Simchi-Levi et al., p.184). Since the motherboard is not manufactured at the time of shipping the chassis, the company incurs additional logistics costs from airfreight. While analyzing the six of the proposed manufacturing solutions to the Dell, it is advisable for the company to manage the 3PI (3rd Party Integration) directly to improve its supply chain efficiency. When the 3PI is managed by Dell directly, the Dell management can enjoy more control over its supply chain activities, and ensure uninterrupted flow of finished products. Another major advantage of this manufacturing solution is that it would help the company trim down integration costs by employing cheap labor. In addition, this manufacturing option may assist the firm to minimize its dependence on external parties. The potential demerit of this solution is that Dell has not adequate expertise in the integration process and this issue may lead to product quality problems. If the supply chain shortage gets deteriorated, the company cannot manage the situation by simply practicing the option 4 (Dell managed 3PI). Under this circumstance, the organization must switch to the option 3A – Integration at SLC/hub. This option is relatively less complex for worldwide procurement, and therefore it may assist the company to resolve the issue. In addition, the management of supply quality engineering is minimized under this option, and hence the chipset supply is likely to improve. However, the option 3A is not very effective considering the difficulties associated with cost accounting. Finally, additional production control and

What issues of discrimination regarding Women in America since the Essay - 3

What issues of discrimination regarding Women in America since the 1920's have been successfully resolved -- and which issues have not yet been resolved - Essay Example ls or women to form a union between two powerful families through marriage and the marriage would be used to signify the bond between the families even if the young girl that was being married was doing so forcefully and unwillingly. However nowadays especially in America women have been given the mandate to marry when they feel like doing so (Tandon 45). This shows how far women have come so as to be liberated and to be responsible of their marital choices and decisions. Arranged marriage was also very rampant in the past where women were forced to marry husbands chosen for them by their parents and whom they did not love. Nowadays however women are given the freedom to marry whoever they choose and so they are free to marry whom they love hence introducing the concept of love in marriages. Unlike in the old days women nowadays are not considered as the man’s property or as economic assets. They are allowed to marry who they want and love (Coontz 56). Time has seen the rising status of the woman in marriage whereby in the current modern society in America women have a significant influence and say in their marriages and are allowed to marry at whatever age they please and they are also free to leave unsatisfying unions whenever they please. They are also free to establish certain rules that should be followed by them and their husbands within the marriage. Polygamy is one of these issues, since it is being practiced secretly by some people in America despite it being outlawed and it shows how the status of women in the current society is still being somehow undermined. Men marrying many wives secretly are enough proof that women are still being undermined in some societies and not being taken seriously. Just like in the old days even today in America the notion of marriage has not changed very much since many women are being forced to endure the state of a bad marriage rather than celebrate it. It has been discovered that even today bride price is being paid

Black Rook in Rainy Weather Essay

I an infrequently lost for words. I like to think of myself as quite an eloquent and articulate speaker and writer, but there are times when I feel neither. It is ironic that the very subject of this poem, a lack of words, or rather a lack of inspiration, is exactly what is holding me back from writing the things I would like to write. Although I know how this poem makes me feel and I know the emotions it conveys, I cannot bring myself to write about them or to speak about them, I simply cannot find the words. Each time I read the poem a rush of thoughts dash through my mind, so quickly that I cannot recollect them in time to consider them in the detail they deserve. This poem deserves consideration, thought, analysis, it deserves appreciation and admiration, because it describes exactly how even the most expressive and eloquent writers are sometimes at a loss for words. Although the poem is a metaphor and is about many things that lie deep beneath the surface of the words, it is beautifully written even in the most literal terms. Plath uses adjectives to describe every object, every movement of the poem, ‘stiff twig’, ‘spotted leaves’. She uses many other poetic devices, such as alliteration in the lines ‘rare, random’, ‘walk wary’, ‘so shine as to seize my senses’ and personification in the lines ‘mute sky’ , ‘minor light may still lean incandescent’. The poet also uses short phrases broken by commas to increase the tempo of the poem and to give it a rushed feeling. However, these poetic devices are not simply used to embellish a purely literal piece of writing. They are used to demonstrate the beauty of the mundane, the magnificence of the ordinary. The poet says ‘I do not expect a miracle or an accident’ which suggests that she is content with the mundane and can see it’s splendour. But as the poem progresses we see that she could not survive on the ordinary, but needed to express herself in her poetry and needed inspiration to do so. Though Plath tries to persuade herself she survive on the ordinary and the imple, it is obvious that desire for inspiration, ‘the angel’, are the only things that can make these mundane situations bearable. She contradicts herself when she states that ‘miracles occur. ’ She contradicts her previous idea that there is beauty in the ordinary and instead describes moments without inspiration being similar to ‘trekking stubborn through this season of fatigue’ . This suggests that during these periods of time she is not living, but barely surviving. Her entire life depends on the moments of inspiration, ‘for that rare, random descent. ’ She is a poet, and her survival depends on her writing. She can only express herself through her writing, and without it, without her inspiration, she feels nothing. This nothingness, this lack of inspiration is to her far worse than the feelings of depression she felt constantly throughout her life. Her ‘fear of total neutrality’ consumes her and scares her. This ‘fear of neutrality’ refers not only to writing, but also to life in general. If one feels nothing, if life is constantly similar to ‘trekking stubborn through this season of fatigue’ then there is no reason to live in the first place. Life is a constant wait for inspiration, for meaning, for purpose, and often this purpose does not appear. Plath realises, unlike many others, that without purpose, without inspiration, there is no beauty in the mundane. Without ‘that rare, random descent’ of an ‘angel’ there is little reason for life at all.

Fourty famous studies that influeneced psychology Essay

Born First, Born Smarter This study involves a person’s intellectual development in correlation to the order in which they were born in relation to their siblings. Two research psychologists, Robert B. Zajonc and Gregory B. Markus, developed a theory in an attempt to explain the relationship between birth order and intelligence. They conducted this study by gathering information from previous research and applied it to the data they collected themselves. A research project was conducted n the late 1960’s that involved testing the intellectual abilities of children born at the end of WWII. They found a strong relationship between the birth order and the Raven test scores. The ones born first scored higher, and the score decreased with the declining birth order. However, the average Raven score for the first born in a two family is only about 5 points higher then that for a last born in a family with nine children. So the more children you have, and the smaller the gap between each child is, the more intelligent each child in succession will be. In Control and Glad of It Researchers Ellen J. Langer and Judith Rodin conducted a field experiment using elderly people in an elderly home to test the outcome of when people are given control as opposed to when people have everything done for them. Langer and Rodin’s prediction was that if the loss of personal responsibility for one’s life causes a person to be less happy and healthy, then increasing control and power should have the opposite effect. Two floors of the elderly home were randomly selected to be observed. One floor was given options for certain things such as there furniture arrangement and which movie they would like to attend. The other floor, was given no such options and had everything arranged and done for them by the staff. The staff was asked to fill out questionnaires about the patients on their floor (the staff new nothing of the experiment). The questionnaires had questions on it to comment about things such as if the patents were sociable, happy, alert, and even how much they visited other patients. The differences between the two groups were incredible. They determined that overall, the increased responsibility group’s condition improved over the three weeks of  the study, while the no-control group was doing progressively poorer. They concluded that when people who have been forced to give up their control and decision-making power are given a greater sense of personal responsibility, their lives and attitudes improve, as is true with the opposing side. More Experience = Bigger Brain Mark R. Rosenzweig and Edward L. Bennett wanted to find out if the brain changes in response to experience. Because this experiment involved long periods of observation and even autopsies to observe the changes in the brain, the two researchers couldn’t use human subjects, so they used rats for the experiment. Three male rats where chosen to participate and assigned to one of three conditions. One rat remained in the colony cage with the rest of the colony. One rat was placed in an â€Å"enriched environment† and one was placed in an â€Å"impoverished environment†. There were 12 rats in each of these conditions for each of the 16 experiments. The standard cage had many rats and had adequate space with food and water always available. The improvised environment was a slightly smaller cage, isolated in a separate room, where the rat was alone with adequate food and water. Finally, the enriched environment was a large cage filled with many toys and furnished with e very luxury a rat could want. The results indicated that the brains of the enriched rats were highly different from those of the impoverished rats. The cerebral cortex of the enriched rats was significantly heavier and thicker then those of the impoverished rats. Also, the study found a significantly greater number of glial cells in the enriched rats’ brains compared with the rats raised in the dull environment. After 10 years of experiment and research the researchers could clearly and confidently state that â€Å"there is no doubt that many aspects of brain anatomy and brain chemistry are changed by experience.† However, many scientists were skeptical of there findings because there were factors that Rosenzweig and Bennett didn’t take into consideration. The enriched rats were handled more which could have been a brain stimulus and the impoverished rats could have been stressed from having no contact with anyone or anything at all. See Aggression†¦Do Aggression One of he most famous and influential experiment ever conducted in psychology history demonstrated how children learn to be aggressive. This study by Albert Bandura and his associates Dorothea Ross and Shelia Ross was carried out in 1961 at Stanford University. The researchers asked for the help of the Stanford University nursery in obtaining thirty-six boys and thirty-six girls raging from ages 3-6. The average age for he children was 4 years and 4 months. Twenty four of the children were assigned to the control group which was the group that wasn’t exposed to any model. The rest of the children were divided into two groups: one exposed to aggressive models and one exposed to non-aggressive models, they were also divided by sex. They eventually had 8 experimental groups divided by gender and level of aggression. First, the experimenter brought a child from one of the groups to a playroom with an adult model. The adult model beat a Bobo doll with a fake mallet while the child played with other toys. Another child was brought in after and the adult model ignored the Bobo doll. This went on for all the groups. 1) The children who were exposed to the violent models tended to imitate the exact violent behaviors they observed when left alone with the Bobo doll. 2) Overall, girls were more likely to imitate the verbal aggression toward the Bobo doll, while the boys showed more physical violence. 3) Boys were significantly more physically aggressive then girls in nearly all the conditions. 4) The boys used the mallet significantly more then girls in almost all of the conditions. 5) The control group was generally less violent then the experimental group.6) in cases with a non-aggressive female, the children used hardly any aggressive language. What You Expect Is What You Get This study involves teacher’s expectancies of pupils and how that affects the students I.Q. gains. Robert Rosenthal and Lenore Jacobson conducted a study where they theorized that when an elementary school teacher is provided with information (such as I.Q. scores) that creates certain expectancies about a student’s potential, either strong or weak, the teacher might unknowingly behave in ways that subtly encourage or facilitate the performance of the students seen as more likely to succeed. An elementary school was chosen and  all the children grades 1-6 were given an I.Q. test near the beginning of the year. The teachers were told that there students were taking the â€Å"Harvard Test of Inflected Acquisition†. This was told to them because this test was supposed to be a predictor for a child’s academic blooming. Teachers believed that students that scored higher would enter a period of increased learning abilities. This was also not true. Children were chosen at random to be within the top 20 percentile of this test and the teachers were informed of this. All other children were the control group of this experiment. At the end of the year the children were tested again using the I.Q. test and the children originally chosen for the top 20% showed a significantly increased score then those of the control group in grades one and two. In grades 3-6 the difference was not so great. The reason for the 1st and 2nd grade development was thought to be because of how younger minds were more malleable then older children and how younger children don’t have a reputation from previous school years. I Can See It All Over Your Face Researchers Paul Ekman and Wallace V. Freisen conducted a study about how facial expressions and emotions are a universal language. The first problem with this experiment was that the researchers had to find subjects that had never been exposed to media or magazines because this would enable the subjects to not truthfully identify a certain emotional expression. Ekman and Freisen found a group of people like this in the Southeast Highlands of New Guinea called the Fore people. They were an isolated Stone Age society with not much contact of any other people outside there environment, let alone any media. They had not been exposed to emotional facial expressions other then those of there own people. The two researchers showed there experimental groups of adults and children pictures of different facial expressions of people from the United States and told them a sentence. They asked them to identify by pointing, to the correct matching facial expression. The adults were given three pictures to choose from and the children were given two. There was not much difference between male and female recognition of expressions, however the children did fair a little better in the experiment. This could have been attributed to the fact that  the children only had to choose between two pictures instead of three. The results for both adults and children clearly support the researcher’s theory that particular facial behaviors are universally associated with particular emotions. The only trouble that the Fore people had was distinguishing between fear and surprise, and this was because these people closely associated fear and surprise as one emotion. Racing Against Your Heart Using their earlier research and clinical observations, two cardiologists, Meyer Friedman and Ray H. Rosenman, developed a model of traits for a specific type of persons behavioral pattern that they believed was related to growing levels of cholesterol and to heart disease. The first pattern, pattern A, had characteristics such as a drive to achieve your goals, a competing personality, multi-tasking that involves meeting deadlines, and extreme alertness. Following this is another type of people, called pattern B. Pattern B is the exact opposite of pattern A. They lacked drive, ambition, desire to compete, and involvement in deadlines. A third set of behaviors developed was called pattern C. This was very much like pattern B but involved anxiety and insecurity. Friedman and Rosenman interviewed about 166 men for there experiment. They first questions they asked them were about there family’s medical history, so they could see if they had CHD. While in this interview the researc hers categorized each man into a pattern A or B category by the way he answered questions, or his tone, or body language. Each subject was asked to keep a log of there diet over the course of a week and blood tests were taken from each of the men to measure cholesterol levels. Friedman and Rosenman matched each man into pattern A and pattern B easily. Each man fit into one of the developed patterns. The researchers found that the men in Pattern A group had significantly higher chances of heart disease and that type A behavior was a major cause of blood abnormalities. However there could be other reasons why Type A had higher chances of heart disease such as, there family’s history. More men in the pattern A group had parents with heart disease. Another difference was that pattern A men smoked more cigarettes a day then did the subjects in group B. This study was very important in the history of psychology for a few  reasons. One way was that it proved certain behavioral patterns can cause major heart related illness. Another is that this study began a new line of research and questioning into t he relationship between behavior and CHD. The largest long-range outcome from this study that has played an important role in creating a new branch of psychology called health psychology. Not Practicing What You Preach This study involves attitudes and actions toward different racial groups. It was determine if what people say is actually what they will do if they come face to face with the problem. Richard T. LaPiere traveled extensively with a young Chinese couple in 1930 and 1931. The couple was very nice and personable and he was glad to be traveling with them. During this time there was a lot of prejudice in the U.S. against Asians. So, LaPiere was very surprised when the Asian couple was graciously accommodated at a very fine hotel that had a reputation for greatly disliking Orientals. Two months later he called the same hotel and asked if they would accommodate a very important Chinese man and they said defiantly not. LaPiere then developed a theory that stated â€Å"What people say is often not what they do†. The study was conducted in two separate parts. First, LaPiere went with his Chinese friends to many hotels and restaurant throughout the U.S. over the course of two years. He took record of how the couple was treated and made sure to first stay out of site of the managers of the establishments to ensure that the couple wouldn’t be treated differently in his presence. The second part of the experiment was for LaPiere to wait 6 months after there trip (to make sure the effect of the Chinese couples visit had faded), and then call each establishment that they went to or stayed at, and asked them if they would accommodate a Chinese person. After almost three years, LaPiere had enough information to make a comparison of social attitudes social behavior. Out of the 251 hotels and restaurants they attended, only one refused the couple and LaPiere service because of the couple’s race. Aside from that instance, all other places accommodated them with average or above average service. When he received most of the letters back with an answer from the hotels and restaurants over 90% of them said they would absolutely not accommodate anyone of the Chinese race. This confirmed LaPiere’s theory that what people  say, is not always how they will act. The Power of Conformity Research psychologist Solomon E. Asch conducted a study to see if people will give into peer pressure and conform to there friends ideas. A person was let into a room (Subject A) with seven other subjects. These seven people, without subject A knowing, were not participants in the experiment, they were helping the experimenter. Each person was asked which line was longer on a card that was shown to them. Subject A went first and then followed was the seven other subjects and then subject A was asked again. They did this several times until one time, all the other subjects disagreed with subject A and all picked the same one, different form his choice. When the card came back to subject A he picked the one everyone else picked. Seventy-Five percent of the time the first subject will conform to the group’s consensus at least once. The powerful effects of group pressures to conform were clearly demonstrated in Asch’s study. There are four factors that could have an effect on the reduction of conformity. These factors are social support, attraction and commitment to the group, size of the group, and gender of the group. If you have people on your side you are more likely to stay with your answer rather then conform. Crowding Into The Behavioral Sink The effects of crowding on our behavior are something that has interested psychologists for decades. One man in particular, John B. Calhoun was especially interested in it when he conducted this study on crowding and social pathology. It may be hard to believe but rats do have a social side. The reason Calhoun used rats were because he needed many subjects for long periods of time that were willing to crowd together for a while. Humans wouldn’t be very good at this. He used a 10Ãâ€"14 foot room and divided it into 4 sections. Section one was connected to section 2 by a ramp, section 2 was connected to section 3 by a ramp, and section 3 was connected to section 4 by a ramp. The walls were electrified so in order to get from section 1 to section 4 you needed to go through all the rooms. The rooms were also filled  with shreds of paper, in order for the rats to make nests. The experimenter filled the rooms with rats. They started with about 4 rats and waited or the rats to multiply until they reached 80. When over 80 were reached some rats were removed so they always had a constant number. When the rats got older, they started to fight with each other for space even though it wasn’t necessarily too crowded. The two end rooms were soon fought for because they got the most space and privacy so the rat that won the fight always stayed on guard at the end of the ramp for security. Some rats became submissive and others always fought. Some of the rats were very sexually active and some wanted nothing to do with it. Some of the mothers in the two middle pens became inadequate. They often left their children and lost all maternal abilities. One environment where the same thing that happened to the rats might happen to humans is in an overcrowded prison. It was found in a very crowded prison where each inmate has approximately 50 square feet, as opposed to one with more room, there were more cases of homicides, suicide, illness, and disciplinary problems. Crowding also has negative effects on problem-solving abilities. When in a small room that’s crowded subjects had a more difficult time listening to a story and putting tighter a puzzle, then did another group with more space and the same tasks. Relaxing Your Fears Away Researcher Joseph Wolpe was a research psychologist specializing in the systematic desensitization treatment of neuroses. The word phobia comes from Phobos, the name of the Greek god of fear. Phobias are divided into three main categories. Simple phobias are phobias that involve irrational fears of animals or specific situations such as small spaces or heights. Social phobias are irrational fears about interaction with others. Agoraphobia is the irrational fear of being in an unfamiliar, open, or crowded space. These are all irrational and all can be treated in similar ways. Systematic desensitization is a behavioral technique that was credited to Wolpe as perfecting and applying it to the treatment of anxiety disorders. Systematic desensitization is the way of unlearning a learned behavior. Reciprocal inhibition is when two responses inhibit each other, and only one may exist at a given moment. There are three steps that a patient must follow in order  to rid themselves of a phobi a. Wolpe says that you cannot be in a complete relaxed state and have an irrational fear at the same time, so the first step is relaxation. He taught the patient to go into a deep state of relaxation whenever they wanted or needed too. The process involves tensing and relaxing your muscles until you have reached a state of complete relaxation. Wolpe also incorporated hypnosis to ensure full relaxation. The next step in the process is for the therapist and patient to develop a list of high anxiety-producing situations involving your phobia. Starting with the least stressful and ending with the most stressful. The final stage is called the unlearning stage. The patient has to go into a deep state of relaxation and the therapist will read off to you your fears of the list. If at any point you feel anxiety the therapist stops you return to your relaxation mode and the therapist will continue. This process continues until the therapist can go through the entire list with you feeling the least bit anxious. The success of their therapy was judged by the patients own reports and by the occasional direct observation. He had a success rate of 91% with the 39 cases he had. The average number of treatment sessions needed was 12.3. Wolpe said that he hasn’t had any patient relapse after a complete desensitization recovery. Who’s Crazy Here, Anyway? David L. Rosenhan conducted an experiment with sane people going into mental facilities claiming to hear voices, to see if the patients would be immediately released if acting completely sane. Rosenhan questioned whether the characteristics that lead to psychological diagnoses reside in the patients themselves or in the situations in which the observers find the patients. Eight subjects including Rosenhan committed themselves to eight different mental hospitals. Each subject was completely sane and in perfect mental health. When committing themselves to the hospital they complained of hearing voices and all but one where admitted and on record as having schizophrenia. Each patient once admitted, acted perfectly sane and showed no signs of schizophrenia yet were treated as though they did have a mental illness throughout their entire stay. They were given medication which they disposed of and were not treated as normal people. It was as if because they  were in the mental hospital, they were automatically considered to not be a real human being. Rosenhan’s study demonstrated rather strongly that normal â€Å"patients† cannot be distinguished from the mentally ill in a hospital setting. According to Rosenhan, this is because of the strength of the mental setting has over the patient’s actual behavior. Once patients are admitted to such a place, there is a strong inclination for them to be viewed in ways that strip them of all individuality. This study surprises me. I’m taken aback that these professionals that have worked with mentally ill patients cannot decipher between a truly mental patient and a completely mentally-healthy patient. It is extremely unprofessional that the staff member/nurse did at one of the facilities by adjusting her bra in front of patients as if they weren’t real people. Thanks For The Memories One of the leading researchers in the area of memory is Elizabeth Loftus at the University of Washington. She has found that when an event is recalled it is not accurately recreated. Instead it’s what’s called reconstructive memory. Loftus defines a presupposition as a condition that must be true in order for the question to make sense. For example, suppose that you have witnessed an automobile accident and I ask you, â€Å"How many people were in the car that was speeding?† The question presupposes that the car was speeding. One experiment done by Loftus was having students in small groups watch a car accident video that was about 1 minute long. After the film ended the students had to answer questions. For half the students the first question was â€Å"How fast was car A going when it ran the stop sign?† The other students had a question that read â€Å"How fast was car A going when I turned right?† The last question for both groups was â€Å"Did you see the stop sign?† In the group that had been asked about the stop sign 53% of the subjects said they saw a stop sign for car A, while only 35% in the â€Å"turned right† group claimed to have seen it. Based on these and other studies, Loftus argues that an accurate theory of memory and recall must include a process of reconstruction that occurs when new information is integrated into the original memory of an event. There is little doubt that in the course of criminal prosecutions, eye witness reports are subject to many sources of  error such as post event information integration.

Color of Water essays

Color of Water essays Before I read "The Color of Water," by James McBride, I saw his appearance on 20/20, discussing his quest to discover the background of his mysterious, marvelous mother. McBride said he didn't even know his mother's maiden name, much less about her Orthodox Jewish background, until he prodded it from her because he needed it for school records. "Shilsky," she told him, impatiently, offering no further details. McBride, who is now about 42 years old, said he asked no more questions of her, but added when he was "bonding" in Black Pride with his college friends, playing bongo drums and jazz music, he'd think: "Shilsky. Shilsky. Something's funny here...". Watching him on television, such a fascinating, articulate and yet entertaining man, made me want to know more about his amazing mother. I received a copy of the book as a gift. None of Ruth McBride's 12 children knew anything of substance about her background. When they asked what color she was, she would answer, "I am no color" and say that God is "the color of water." Ruth Shilsky, whose father was an abusive Orthodox Jewish Rabbi, treated her and her mother extremely cruelly when she was a young girl in Suffolk, Virginia. Jews were discriminated against second only to blacks. But Ruth fell in love with a young black man, became pregnant by him, and was sent to live with an aunt in New York city. She never went home again. She felt much more at home in 1940s Harlem, ...

Barack Obama - Terms as President

Barack Obama - Terms as President President Barack Obama served two terms in the White House and ended up being more  popular than his predecessor, George W. Bush, at the the time he left office, according to public opinion polls. But Obamas popularity didnt mean he  could have run for a third term, as some conspiracy theorists suggested. U.S. presidents have been limited to serving only two four-year terms in the White House since 1951, when the 22nd Amendment to the Constitution was ratified.   Obamas terms as president began on Jan. 20, 2009. He served his last day  in office  Jan. 20, 2017. He served eight years in the White House and was succeeded by Republican President Donald Trump. Obama, like most ex-presidents, hit the speaking circuit after leaving office. The Third Term Conspiracy Theory Conservative critics of Obama began raising the prospect of a third term early in his tenure in the White House. Their motivation was the raise money for conservative candidates by way of scare tactics. In fact, subscribers to one of former U.S. House Speaker Newt Gingrichs email newsletters were warned of a specific scenario that must have seem rather frightening President Barack Obama running for, and winning, a third term as president in 2016. Conspiracy theorists believed the 22nd Amendment limiting presidents to two terms in office somehow would be wiped from the books by the time the 2016 campaign rolled around, after Obama had won re-election to a second term in 2012. That, of course, never happened. Trump pulled off an upset against Democrat Hillary Clinton. Spreading Rumors About a Third Term The email from Gingrich Marketplace, which is managed by the conservative group Human Events, claimed Obama would win a second term and then go on to win a third term that would begin in 2017 and last through 2020 despite a constitutional ban on such a thing. The truth is, the next election has already been decided. Obama is going to win. Its nearly impossible to beat an incumbent president. Whats actually at stake right now is whether or not he will have a third-term, wrote an advertiser to subscribers of the list. The message itself was not written by the former 2012 presidential hopeful. The email neglected to mention the 22nd Amendment, which reads in part: No person shall be elected to the office of the President more than twice ... The Notion of a Third Term in Wartime Still, even some pundits writing in the mainstream media raised the question of whether Obama could serve a third term, depending on world events at the time a second term would expire.  Faheem Younus, a clinical associate professor at the University of Maryland and founder of the website Muslimerican.com, wrote in The Washington Post that attacking Iran could give Americans reason to keep Obama as president for a third term. Wartime presidents can sell a Double Whopper to a vegetarian, Younus wrote.  As the festinate decision of bombing Iran turns into a global conflict, dont expect our constitutional law professor turned president to decline his partys suggestion: if it can be ratified; it can be repealed. Repealing the 22nd Amendment - which some argue was never vetted publicly - is not unthinkable. The notion of a third term was not unthinkable at one time. Before the ratification of the 22nd Amendment,  Franklin Delano Roosevelt  was elected to four terms in the White House - in 1932, 1936, 1940, and 1944. He is the only president to have served more than two terms. Other Obama Conspiracy Theories Obama critics spread numerous conspiracy theories during his two terms in office. At one point, nearly one in five American wrongly believed Obama is a Muslim. Numerous widely circulated emails erroneously claimed Obama  refused to recognize the National Day of Prayer. Others believed his signature accomplishment, an overhaul of health care in the United States, paid for abortions. The most nefarious of the conspiracy theories, one propagated by Trump himself, was that Obama was born in Kenya and not Hawaii, and that because he was not born here he was not eligible to serve as president. So maybe a third term for Obama wasnt such a crazy idea, all things considered.

Do the Financial Institutions Affect the Economic Growth of A Region Essay

Do the Financial Institutions Affect the Economic Growth of A Region of Not - Essay Example This theory was the base of Lucas's neutrality-of-money paper. The neoclassical tradition emphasizes that the demand for a product in the market and the quantity supplied determine the employment and labour cost. Milton Friedman had also constructed mechanisms with a similar view. The minor misconceptions in the Friedman's theory were corrected by Lucas by establishing a perfect balance between the "long-run" and the "short-run" non-neutrality essential for money based business cycles. The basis of both their constructs is that money is "exogenous†. They simply mean the central authority handling it can easily determine the constant supply of money. We all know the institution of banking is the above mentioned authority in the modern economy. By analysing the banking sector further, with the Lucas's theory, we will be able to determine whether the modern day money-creating systems lean towards neutrality or non-neutrality of money. Both the scholars did not consider the relatio n of bank assets and money as well as the borrower’s use of these assets. The banking sectors operate actively by investing on assets and lending the profits earned to others. We all know how influential the banking sector innovations can be on the core business management strategies. The best example is the 1985 game of mergers and acquisitions. Schumpeter said, innovation is the base of market power which will provide great temporary powerful positions, but this monopoly power will erode soon. It is true. We see the rise and fall of several banks, boosting the economy of a region considerably and disappearing like a bubble in a short time. The reason for this is, several banks spring up following one successful model, without any proper goal. They are just â€Å"lured imitators† according to Schumpeter and they are the main factors causing the short term monopoly in the market. Certain scholars like Hicks argue these quick profits created by the short term monopolies are quite important to keep the market active, inspired and running. Schumpeter’s innovation concept doesn’t fit the banking sector alone. In fact, they fit all technological and developing sectors. Innovations in finance will increase investments on the other sub sectors, creating a more technically sophisticated world. The role of speculators or middle men who act as a bridge between the financial sectors and the industries requiring investment also plays an important role in determining the actions of the financial institutions. Keynes’s words stating speculators are not mere bubbles, but they are capable of making a whole institution become bubble in the speculation whirlpool is worth consideration. According to Schumpeter strong financial institutions are the base of a countries economic growth, as it is innovative and kindles growth. But, Lucas, Levine and many other authors just considered the role of such organizations like banking have been â€Å"badl y over-stressed† in relations to economical growth of a country. There are some key questions to answer 1. How do the financial institutions emerge and why? 2. Under what circumstances do the financial institutions develop rapidly? 3. Are they really necessary and do they actually affect the money flow of a region or country? Any innovative organization wants more money to grow. They are the drivers behind these financial instit
