Environmental Issues in Business Aviation Assignment

Environmental Issues in Business Aviation - Assignment Example The significant environmental hazards in the Business aviation aircraft industry are the green house emissions and the noise (A Greener Future 2011). These gases emitted by business aviation aircrafts especially carbon dioxide and carbon monoxide (GAMA 2010) creates a layer in the atmosphere trapping heat on the earth’s surface. This heat in turn causes the Global warming (International Business 2011), alters the pattern of precipitation and the pattern of the heat waves. Noise causes annoyance to people; fortunately, current business aviation aircrafts produce less noise as compared to earlier business aviation aircrafts. There is a need to develop lasting solution to the management of emissions. This involves all the stakeholders to play active roles. The approach is best achieved through technology, finances or infrastructure, improvements in operations, alternative fuels and market focused measures. Technology Technology in business aviation is demanding efficiency. Business aviation aircrafts must be as light as possible and consume less fuel as possible. The business aviation has collaborated with other stakeholders in environmental issues work group, business aviation environmental projects, technology enhancements by engine manufactures, aerodynamic enhancements by business aviation aircrafts manufactures, airspace management and technology, voluntary offset programmes, flight department participation and operational measures (GAMA 2010). Establishing common and practical goals in the engine and airframe technology enhancements are particularly vital in the management of environmental issues (GAMA 2010).

Establishing common and practical goals in the engine and airframe technology enhancements are particularly vital in the management of environmental issues (GAMA 2010). The engines of today are designed to economise on fuel, produce less noise and emit fewer gases. The business aviation airframes are also built in the sense of reducing noise and carry more weight. This technology commitment is expected to continue; and in the future years, it is expected that business aviation aircrafts will be much lighter and consume less fuel. The emissions have drastically been reduced in the business aviation sector. The current business aviation aircraft engines (GAMA 2010) emit less hazardous gas and produces less noise. A business aircraft produces 3.5 tonnes of carbon dioxide per flight (International Business 2011). The carbon dioxide emissions in one year by all the business aviation aircraft combined produce emissions similar to one medium sized power plant (International Business 2011). Reduction of carbon emissions (ICAO 2011) in business aviation aircrafts is done on various ways, checking on operator practices, air traffic control, engine design, airframe design and use of alternative fuels. Carbon is the principal component. The engines use oxygen to burn the fossil fuel,

Assignment Questions Chapters 5-7 Psychology Essay 1. Most current studies aimed at understanding human memory are conducted within a framework known as information-processing theory. This approach makes use of modern computer science and related fields to provide models that help psychologists understand the processes involved in memory. The general principles of the information processing approach to memory include the notion that memory involves three distinct processes. The first process, encoding, is the process of transforming information into a form that can be stored in memory. The second process, storage, is the process of keeping or maintaining information in memory. The final process, retrieval, is the process of bringing to mind information that has been stored in the memory (p.168). Two influential theorists concerning the information-processing theory are Richard Atkinson and Richard Shiffrin. They characterized memory as three different, interacting memory systems: sensory memory, short-term memory, and long-term memory. Sensory memory is the memory system that holds information from the senses for a period of time ranging from only a fraction of a second to about 2 seconds. Sensory memory can take in an enormous amount of information, but it can only hold on to it for a very brief period of time (p.169). Short-term memory is the component of the memory system that holds about seven (from five to nine) items for less than 30 seconds without rehearsal; also called the working memory. When short-term memory is filled to capacity, displacement can occur. In displacement, each new incoming item pushes out an existing item, which is then forgotten (p.170). Long-term memory (LTM) is the memory system with a virtually unlimited capacity that contains vast stores of a persons permanent or relatively permanent memories. There are no known limits to the storage capacity of this memory system, and long-term memories can persist for years, some of them for a lifetime. Information in long-term memory is usually stored in semantic form, although visual images, sounds, and odors can be stored there as well (p.174). 2. The analogy heuristic involves comparing a problem to others you have experienced in the past. The idea is that if a particular strategy worked with similar problems in the past, it will be effective for solving a new one. Another heuristic that is effective for solving some problems is working backward, sometimes called the backward search. This approach starts with the solution, a known condition, and works back through the problem. Once the backward search has revealed the steps to be taken and their order, the problem can be solved (p.207). Another popular heuristic strategy is means-end analysis, in which the current position is compared with a desired goal, and a series of steps are formulated and then taken to close the gap between the two. When you adopt a heuristic strategy, it may or may not lead to a correct solution. By contrast, the algorithm is a problem-solving strategy that always lead to a correct solution if it is applied appropriately (p.208). 3.Research suggests that there are both advantages and disadvantages to learning two languages early in life. One of the pluses is that, among preschool and school-age children, bilingualism, fluency in at least two languages, is associated with better executive control skills on language tasks. Executive control skills enable bilingual children to suppress impulsive responses to verbal tasks and, as a result, think more carefully about them. Thus, executive control skills are important in learning to read and write. On the downside, even in adulthood, bilingualism is sometimes associated with decreased efficiency in memory tasks involving words. However, bilinguals appear to develop compensatory strategies that allow them to make up these inefficiencies. Consequently, they often perform such tasks as accurately as monolinguals, though they may respond more slowly. Researchers have found that there is no age at which it is impossible to learn a new language. While it is true that those who begin earlier reach higher levels of proficiency, age is not the only determining factor (p.214). There is one clear advantage to learning two languages earlier in life, however. People who are younger when they learn a new language are far more likely to be able to speak with an appropriate accent. One reason for this difference between early and late language learners may have to do with slight variations in neural processing in Brocas area, the area of the brain that controls speech production. Research suggests that bilinguals who learned a second language early rely on the same patch of tissue in Brocas area for both of the languages they speak. In those who learned a second language at an older age, two different sections of Brocas are are active while they are performing language tasks (p.215). 4. Charles Spearman observed that people who are bright in one area are usually bright in other areas as well. In other words, they tend to be generally intelligent. Spearman came to believe that intelligence is composed of a general ability that underlies all intellectual functions. Spearman concluded that intelligence tests tap this g factor, or general intelligence, and a number of s factors, or specific intellectual abilities. Spearmans influence can be seen in those intelligence tests, such as the Stanford-Binet, that yield one IQ score to indicate the level of general intelligence. Howard Gardner also denies the existence of a g factor. Instead, he proposes a theory of multiple intelligences that includes eight important forms of intelligence, or frames of mind. The eight frames of mind are linguistic, logical-mathematical, spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, and naturalistic. In recent years, he has proposed a ninth type of intelligence, one that he calls existential intelligence, deals with the spiritual realm and enables us to contemplate the meaning of life. He first developed his theory by studying patients with different types of brain damage that affect some forms of intelligence but leaves other intact. The most controversial aspect of Gardners theory is his view that all forms of intelligence are of equal importance. In fact, different cultures assign varying degrees of importance to the types of intelligence (p.216-217). 5. I would perform a fixed-ratio (FR) schedule, in which a reinforcer is given after a fixed number of correct, non reinforced responses. So, if my dog knew that after rolling over correctly ten times without getting reinforced meant that she would get a reinforced after those ten times, she would then learn that after rolling over ten times correctly, she would be reinforced (p.147). In fixed-rate schedules response rates are very high, and the higher the ratio, the more resistant to extinction (p.148). 6. Psycholinguistics is the study of how language is acquired, produced, and used and how the sounds and symbols of language are translated into meaning. Psycholinguists use specific terms for each of the five basic components of language. The smaller units of sound in a spoken language-such as b or s in English-are known as phonemes. Three phonemes together form the sound of the word cat: c (which sounds like k), a, and t. Combinations of letters that form particular sounds are also phonemes, such as the th in the and the ch in child. The same phoneme may be represented by different letters in different words; this occurs with the a in stay and the ei in sleigh. And the same letter can serve as different phonemes. This letter a, for example, is sounded as four different phonemes in day, cap, watch, and law. Morphemes are the smallest units of meaning in a language. A few single phonemes serve as morphemes, such as the article a and the personal pronoun I. The ending -s gives a plural meaning to a word and is thus a morpheme in English. Many words in English are single morphemes-book, word, learn, reason, and so on. In addition to root words, morphemes may be prefixes (such as re- in relearn) or suffixes (such as -ed to show past tense, as in learned). The single morpheme reason becomes a dual morpheme in reasonable. The morpheme book (singular) become two morphemes in books (plural). Syntax is the aspect of grammar that specifies the rules for arranging and combining words to form phrases and sentences. The rules of word order, syntax, differ from one language to another. For example, an important rule of syntax in English is that adjectives usually come before nouns. So English speakers refer to the residence of the U.S. president as the White House. In Spanish, in contrast, the noun usually comes before the advective, and Spanish speakers say la Casa Blanca, or the House White. Semantics refers to the meaning derived from morphemes, words, and sentences. The same word can have different meanings depending on how it is used in sentences: I dont mind. Mind your manners. He has lost his mind. Or consider another example: Loving to read, the young girl read three books last week. Here, the word read is pronounced two different ways, and in one case, is the past tense. Pragmatics, is the term psycholinguists use to refer to aspects of language such as intonation, the rising and falling patterns that are used to express meaning. For example, think about how you would say the single word cookie to express each of the following meanings: Do you want a cookie? or What a delicious looking cookie! or Thats a cookie. The subtle differences reflect your knowledge of the pragmatic rules of English (P.210-211). 7. An intelligence test is a measure of general intellectual ability. An individuals score is determined by how his responses compare to others of his or her age. Thus, intelligence tests are norm-referenced. All psychological tests, including all the various types of tests that measure cognitive ability, are judged according to the same criteria.They must provide consistent results. An intelligence test must have reliability; the test must consistently yield nearly the same score when the same person is tested and then retested on the same test or an alternative form of the test. The higher the correlation between the two scores, the more reliable the test. Tests can be highly reliable but worthless if they are not valid. Validity is the ability or power of a test to measure what it is intended to measure. Once a test is proven to be valid or reliable, the next requirement is norm-referenced standardization. There must be standard procedures for administering and scoring the test. Exactly the same directions must be given, whether written or oral, and the same amount of time must be allowed for every test taker. But even more important, standardization means establishing norms, age-based averages, by which all scores are interpreted. A test is standardized by administering it to a large sample of people who are representative of those who will be taking the test in the future. The groups score are analyzed, and then the average score, standard deviation, percentile rankings, and other measures are computed. These comparative scores become the norms used as the standard against which all other scores on that test are measured. Reliability, validity, and standardization are especially important with regard to intelligence tests because the kinds of decisions that are sometimes based on intelligence test scores can have grave consequences. For example, a few years ago the U.S. Supreme Court ruled that is unconstitutional to execute individuals who have mental retardation. Thus, a psychologist who is charged with the responsibility of administering an intelligence test to a person who will or will not be subject to the death penalty at least partly on the basis of his or her intelligence test score must ensure that the test given is reliable and valid and has been properly standardized. Likewise, childrens scores on these tests are often used to place them in special school programs that, in a very real sense, change the course of their lives for years to come. In fact, such a goal was the impetus for the development of the first standardized intelligence test (p.219). 8. In memory loss there are two broad categories that involves this kind of memory loss, amnesia and dementia. Amnesia is a partial or complete loss of memory due to loss of consciousness, brain damage, or some psychological cause. Unlike the memory disorders that are experienced by some older adults, amnesia can be experienced at any age. In some cases, amnesia takes the form of an inability to store new information. This kind of amnesia is known as anterograde amnesia. Anterograde amnesia is the inability to form long-term memories of events occurring after a brain injury or brain surgery, although memories formed before the trauma are usually intact and short-term memory is unaffected. Some individuals with amnesia can form new memories, but they cannot remember the past, a disorder known as retrograde amnesia. Retrograde amnesia is a loss of memory for experiences that occurred shortly before a loss of consciousness. These people often lack knowledge of themselves and/or the events surrounding the development of their memory loss. It is not unusual for a person to have both retrograde and anterograde amnesia with regard to the events that immediately preceded and followed a serious car crash or other traumatic event (p. 189). Another form of memory loss is dementia. Dementia is a state of mental deterioration characterized by impaired memory and intellect and by altered personality and behavior. Dementia can result from such conditions as cerebral arteriosclerosis (hardening of the arteries in the brain), chronic alcoholism, and irreversible damage by a small series of strokes. Dementia is most common among older adults. However, diseases such as HIV/AIDS can cause dementia to develop in a younger person as well. About 50 to 60% of all cases of dementia result from Alzheimers disease. This is a progressive deterioration of intellect and personality that results from widespread degeneration of brain cells (p.190). 9. People reconstruct memories, piecing them together using schemas to organize fragments of information, a process that has both advantages and disadvantages. Information that fits with preexisting schemas can be efficiently remembered, but schemas can also introduce distortions into memory. Sir Frederick Bartletts research demonstrated how reconstructive processing changes memory over time (p.178). Most memories do not include source information, so memories for sources must be reconstructed. Source monitoring results in encoding of source memories. Flashbulb memories are different from others in that they always include source information, although the source information is subject to reconstruction changes over time (p.179). Autobiographical memories are reconstructed memories that include factual, emotional, and interpretive elements. They are subject to positive bias (p.180). 10. Bandura suspected that aggression and violence on television programs, including cartoons, tend to increase aggressive behavior in children. In several classic experiments, Bandura demonstrated how children are influenced by exposure to aggressive models. One study involved three groups of preschoolers. Children in one group individually observed an adult model punching, kicking, and hitting a 5-foot, inflated plastic Bobo Doll with a mallet, while uttering aggressive phrases. Children in the second group observed a nonaggressive model who ignored the Bobo Doll and sat quietly assembling Tinker Toys. The children in the control group were placed in the same setting with no adult present. Later, each child was observed through a one-way mirror. Those children exposed to the aggressive model imitated much of the aggression and also engaged in significantly more nonimitative aggression than did children in either of the other groups. The group that observed the nonaggressive model showed less aggressive behavior than the control group. The researchers concluded that of the three experimental conditions, exposure to humans on film portraying aggression was the most influential in eliciting and shaping aggressive behavior (p. 158-159). 11. Experiencing hunger pangs when you smell your favorite food is an example of classic conditioning.Your stomach rumbles when you smell your favorite food because smell and taste are so closely linked that food odors, functioning as conditioned stimuli, can actually make you think you are hungry even if you have just finished a large meal. The conditioned stimulus (CS) would be the presence of the smell of your favorite food which brings about the unconditioned stimulus (US) hunger pangs. Because humans do not need to be taught to be hungry for food, the act of feeling hungry would be the unconditioned response (UR). The conditioned response (CR) would be knowing that you will get hungry when you smell your favorite food (p.143). 12. Critics argue that therapists using hypnosis and guided imagery to help their patients recover repressed memories of childhood sexual abuse are actually implanting false memories in those patients. They are especially critical of claims of recovered memories in the first three years of life, because the hippocampus and areas of the cortex are not well developed enough to store long-term memories. Therapists who use these techniques believe that a number of psychological problems can be treated successfully by helping patients recover repressed memories of sexual abuse. These therapists believe that a process called repression, a form of motivated forgetting, can cause traumatic memories to be so deeply buried in an individuals unconscious mind that he or she has lost all awareness of them (p.192-193). 13. Writing notes, making lists, writing on a calendar, or keeping an appointment book is often more reliable and accurate than trusting to memory. But if you need information at some unpredictable moment when you dont have aids handy, several mnemonics, or memory devices, and study strategies have developed over the years to aid memory. Mnemonics, or rhymes are a common aid to remembering material that otherwise might be difficult to recall. As a child, learning to recite i over e except after c when you were trying to spell a word containing that vowel combination is an example of a mnemonic. The method of loci is a mnemonic device that be used to when you want to remember a list of items such as a grocery list. Select a familiar place your home, for example and simply associate the items to be remembered with locations there. For example, visualize the first item you want to remember in its place on the driveway, the second in the garage, and the third at the front door, and so on until you have associated the item you want to remember with a specific location. Overlearning is another method of improving memory. Overlearning is practicing or studying material beyond the point where it can be repeated once without error. It makes material more resistant to forgetting (p.173). 14. Bandura proposed that four processed determine whether observational learning will occur: Attention: The observer must attend to the model. Retention: The observer must store information about the models behavior in memory. Reproduction: The observer must be physically and cognitively capable of performing the behavior to learn it. In other words, no matter how much time you devote to watching Serena Williams play tennis or listening to Beyonce sing, you wont be able to acquire skills like these unless you possess talents that are equal to theirs. Reinforcement: Ultimately, to exhibit a behavior learned through observation, an observer must be motivated to practice and perform the behavior on his own (p.156). 15. In some cases, we are hampered in our efforts to solve problems in daily life because of functional fixedness, the failure to use familiar objects in novel ways to solve problems. Objects you use everyday such as, tools, utensils, and other equipment are what help you perform certain functions. Although, you probably do not think to use the normal functions of such objects in new and creative ways. Suppose you wanted a cup of coffee, but the glass pot for you coffeemaker was broken. If you suffered from functional fixedness, you might come to the conclusion that there was nothing you could do to solve the problem at that moment. But, rather than thinking about the object you dont have, think about the function that it needs to perform. Another impediment to problem solving is mental set, the tendency to continue to use the same old method even though another approach might be better. Perhaps you hit on a way to solve a problem once in the past and continue to use the same technique in similar situations, even though it it not highly effective of efficient. The cognitive process that underlies both functional fixedness and mental set is confirmation bias, the tendency to selectively pay attention to information that concerns preexisting beliefs and ignore data that contradict them. For example, when faced with an operating system crash, most computer users know that the first line of defense is to reboot. Every time rebooting solve the problem, confirmation bias in favor of rebooting as a solution for computer problems becomes stronger. As a result, when a problem arises that proves resistant to rebooting, most of us try rebooting a few more times before we confront the reality that rebooting isnt going to solve the problem (p.209).

Fight Club by Jack Palahniuk :: Movie Film Fight Club Jack Palahniuk Essays

Fight Club by Jack Palahniuk â€Å"You are not your job. You are not how much you have in the bank. You are not the contents of your wallet. You are not your khakis. You are not a beautiful and unique snowflake. What happens first is you can’t sleep. What happens then is there’s a gun in your mouth. And what happens next is you meet Tyler Durden. Let me tell you about Tyler. He had a plan. In Tyler we trusted. Tyler says the things you own, end up owning you. It’s only after you’ve lost everything that you’re free to do anything. Fight Club represents that kind of freedom. First rule of Fight Club: You do not talk about Fight Club. Second rule of Fight Club: You do not talk about Fight Club. Tyler says self-improvement is masturbation. Tyler says self-destruction might be the answer.† The novel Fight Club, by Jack Palahniuk was published in 1996 and released as a motion picture starring Brad Pitt and Edward Norton in October of 1999. Both the novel and motion picture proved to be very successful in their release to the public for one simple reason: Fight Club is a reflection of the suffering experienced by the ‘Generation X’ male who feels trapped in a world of the grey-collar (or service) working-class, a world filled with materialism and distractions, a group of men raised in single-parent families often devoid of a male role-model, and a world where there is no great cause for the average North American male to fight for. Whether consciously, or subconsciously, the average ‘Generation X’ male of modern society can relate to and understand Fight Club, which makes both the novel and motion picture such an important proclamation regarding the state of our modern culture. In Fight Club, we meet our main character who comes to us without a name. He can be referred to as ‘Jack’ but his name is not important. He comes to us without a name because he represents ‘any man’, any one of those ‘Generation X’ males living in our society at present. Jack is a thirty-year old man employed as a recall coordinator for a major automobile company. He lives in a condo that is furnished with all the comforts of modern society, namely mass-produced furnishings that can be found in the homes of millions across North America. Jack owns a car and has obtained a respectable wardrobe for himself over the course of time.

War and Terror - It’s Time to Stop the Killing :: Argumentative Persuasive Argument Essays

War and Terror - It’s Time to Stop the Killing Somewhere within the last 120,000 thousand years, our ancestors began migrations quite different from any that appear in the archeological record preceding that time and somewhere between forty and fifty thousand years ago those migrations accelerated to the point that Cro Magnon hominids, our forebears, settled every nook and cranny on the planet. The last major migration occurred when the land bridge opened up in Siberia, as the glacier receded ten thousand years ago, and Homo Sapiens, who our species had become by then, trudged all the way to Tierra del Fuego within a thousand years or so. Jared Diamond (â€Å"The Third Chimpanzee† & â€Å"Guns, Germs, and Steel†) makes a case for some biological change, probably related to speech, as the variable making such migrations possible. He also makes the observation that these human migrations were coincident with the extinction of large mammals. The archeological evidence seems to bear this out. All over the planet there is fossil evidence of the extinction of one large mammal after another at approximately the same time the human migrations happened in that part of the world. Some scientists speculate that the cause of these extinctions is more complicated than the fact that they are coincident with the expansion of the number of humans and they are probably right; but something of major proportions in the evolution of our species definitely changed to allow humans to sweep across all but the most uninhabitable places on earth in a relatively short period of time. Dr. Diamond is careful to temper his speculation with the caution that all the facts are not yet in, and probably never will be, I might add. As a biology-oriented scientist, he continues to look to some physical/anatomical change to account for the advances made by humans resulting in our capacity to take on the unknown dangers lying beyond the next range of mountains or across the next river. For a couple of million years humans had evolved fairly slowly toward that point when a â€Å"great leap† occurred in the pace of our development. Anatomically we are about the same now as we have been for the last 125,000 years, so the guess is that some language advancement made the difference.

Jesus’ Blood Never Failed Me Yet Essay

Known as a minimalist and experimental composer, Richard Gavin Bryars unleashed an emotionally intimate constructed piece out from a lone old vagrant singing, Jesus’ blood never failed me yet, this one thing I know, for he loves me so†¦ Originally recorded from footage of a documentary by his friend Alan Power in 1971 (Grimshaw), this aged voice served as the focal point and backdrop for Bryars’ poignant yet challenging work unfolding and reiterating itself over the course of 74 minutes in length. Whereas music that falls under Minimalist movement, sometimes associated the emotional neutralization of repeated materials, Bryars’ has the reverse effect in which rather than numbing the listener’s sensibilities, he heightens them and instead of imposing postmodern indifference toward the subject matter, it forces confrontation with it (Grimshaw). The entire lengthy music might deflate the interest of its listeners as the lines simply repeated over the recording, but Bryars managed to extract the spirit of the tramp’s captive song as he slowly introduced an accompaniment. The first part was merely the sole voice of the old man then eventually enhanced by string quartet, followed by plucked bass and guitar. Moreover, as the instruments subsequently fade out, the tramp’s song continues and eventually underscored by a much richer sounding ensemble of low strings, then woodwinds, brass, and delicate percussion and finally full orchestra and choir (Grimshaw). The soul of the music originated from the compassionate nature of the old vagrant who sang the religious tune during the recording of Power’s documentary that was about the life of street-people around Elephant and Castle and Waterloo in London. Bryars’ recounted; while they are filming the documentary, some people broke into drunken ballad or opera songs, but there was a particular homeless old man sang â€Å"Jesus’ Blood Never Failed Me Yet†. When he played it at home, he noticed the exact tune of the singing to his piano, and, he discerned that the first section of the song that is 13 bars in length formed an effective loop that repeated in a slightly unpredictable way. Therefore, he took the tape to Leicester and copied the loop onto a continuous reel of tape having the idea of adding orchestrated accompaniment to it. During the act of copying, he left the door that lead to the large painting studios, and when he came back, he found people weeping and silently listening over the old man’s singing, at that point, he realized a great emotional influence from the noble faith and tranquil music (Howse), a merely accidental root behind this epic. This particular Bryars’ piece was a breakthrough as there were other versions made during the latter years. Tom Waits singing along with it in 1990 and Jars of Clay released their own version on their album Who We Are Instead in 2003, aside from the fact that it was also used for several theatrical presentations. Covering credits for its very straightforward message to the people, the unyielding constancy of the lyrics—repeated over 150 times—essentially keeps the music from achieving greater feats. It is said that no matter how many times you paint a house, it remains to be the same house. Still, that verse holds together the entirety of the minimalist piece, a factor that you cannot simply neglect. Focusing on keeping his music very simple yet haunting, this composer and double bassist is a native from Goole, East Riding of Yorkshire, England and born on January 16, 1943. His first musical reputation was as a jazz bassist working in the early sixties with improvisers Derek Bailey and Tony Oxley. He abandoned improvisation in 1966 and worked for a time in the United States with John Cage, until he collaborated closely with composers such as Cornelius Cardew and John White. He taught in the department if Fine Art in Portsmouth, Leicester from 1969 to 1978, and there he founded the legendary Portsmouth Sinfonia, an orchestra whose membership consisted of performers who â€Å"embrace the full range of musical competence† — and who played or just attempted to play popular classical works. He also founded the Music Department at Leicester Polytechnic (later De Montfort University) and served as professor in Music from 1986 to 1994. Meanwhile, his first major work as a composer owe much to the so-called New York School of John Cage—with whom he briefly studied, Morton Feldman, Earle Brown and minimalism. His earliest piece was The Sinking of Titanic (1969) and was originally released under Brian Eno’s Obscure Label in 1975 and the Jesus’ Blood Never Failed Me Yet (1971) both famously released in new versions in the 1990s on Point Music Label, selling over a quarter of a million copies. The original 1970s recordings have been re-released on CD by Virgin Records. A major turning point in his development was his first written opera Medea, premiered at the Opera de Lyon and Opera de Paris in 1984. He has written another two operas, both with libretti by his long time collaborator Blake Morrison: Doctor Ox’s Experiment, and G, commissioned by the Staatstheater Mainz for the Gutenberg 600th Anniversary. Aside from that, Bryars has also produced a large body of chamber music including three string quartets and a saxophone quartet both for his own ensemble and for other performers. He has also written extensively for strings as well as producing concertos for violin, viola, cello, double bass, saxophone and bass oboe.

The Traits Model of Leadership

The Traits Model of Leadership Hashtag: #labourleadership Mark of a Good Leader The Traits Model of Leadership There is a popular impression that being an intellectual is one thing and being an effective leader is another. Intellectuals, according to the literature, are often seen as eccentric, iconoclast, awkward, irresponsible, self-absorbed, and individualistic thus incapable of leading collective activities.   For instance, in relation to #labourleadership or UK’s Labour Party leadership where alleged anti-austerity Jeremy Corbyn was recently elected, several politicians who led this political party in the past were not effective leaders. The late Michael Foot according to author Bruce Macfarlane had very strong academic and intellectual credentials but was not prepared to compromise his beliefs for the sake of political expediency. In fact, he is always remembered as the leader who endorsed the dispatched of the task force in the Falklands War in 1982 and led the Labor Party to its greatest election defeat in 1983. The traits model of leadership suggests that the characteristics of a person are a predictor of both successful and unsuccessful leaders.   For instance, although an intelligent, self-confident, determined, honorable, and sociable person has the capacity to be a leader, he or she according to study needs to possess the five personality factors – neuroticism, extraversion, openness, agreeableness, and conscientiousness. These personality factors suggest that the most effective leaders have tendencies to be depressed, anxious, insecure, and hostile. They are not only sociable and assertive, and have positive energy, but informed, creative, insightful, and curious. They are people that have the tendency to accept, confirm, trust, and nurture. Finally, they are systematic, prepared controlled, dependable, and decisive individuals. A leader, according to the literature needs to be effective in guiding the conduct of others, thus must be effective in conveying meanings and intentions, and in receiving them. A leader for that matter does not necessarily need to be an intellectual, a quality of a person that according to organization and management expert and author Chester Bernard does not work well with leadership.   The reason is that people with superior intellect and greater intellectual accomplishments are often absent-minded, non-punctual, non-decisive, and not interested in people.   Although intellectual abilities are sometimes a critical element in leadership, it is not a substitute for the other essential qualities of leadership such as those mentioned earlier.

None Creature Can Fly with Just One Wing Successful leadership occurs where heart and mind meet, the two powerful wings that allow a leader to excel.   According to the study, leaders need to have enough intellect in order to understand and perform the tasks at hand, a quality that gets people in the leadership door. However, although intellect is considered a fundamental leadership trait, it is not enough to make a leader. For instance, aside from intellect, a leader need to motivate, guide, inspire, listen, persuade, and create resonance in order to execute a vision. Intellect, according to Albert Einstein, has â€Å"powerful muscles, but no personality†¦it can serve but cannot lead†.   Moreover, Swami Vivekananda, a key figure in Indian philosophy noted in one of his London lectures that â€Å"intellect is blind and cannot move by itselfInactive secondary help, the real help is feeling†.   Moreover, intellect without feelings cannot generate â€Å"authentic power†, the sustainable type of power over individual and organizations that according to the literature is the result of mastery of authenticity and emotional intelligence – unconditional trust, respect, honesty, truth, fairness, openness, care, and forgiveness.   Authentic power is generated by a leader’s capacity to do things with others while the quality of interactions and relationships is determined by the level of his or her emotional and social intelligence.

Comparison of the Etiology, Diagnosis, and Treatment of DID and PTSD

Comparison of the Etiology, Diagnosis, and Treatment of DID and PTSD Introduction Psychology is the academic discipline dealing with the study of human behaviour and mental functions (Burton, 2010). As such, psychologists are described as social or cognitive scientists. The scientists and professionals explore human characters, such as perception, emotions, and personality. The aim of such exploration is to assess and treat psychological disorders.Advertising We will write a custom essay sample on Comparison of the Etiology, Diagnosis, and Treatment of DID and PTSD specifically for you for only $16.05 $11/page Learn More Numerous studies have been conducted in the past to try and explain why people act and behave the way they do. Information gathered from such analyses is taken into consideration when making decisions in many contemporary organisations (Barlow Durand, 2011). Organisations that use such information in their operations include the government and private companies and corporations. The information is especially important when hiring personnel. Individuals psychological information helps other people in making informed decisions when dealing with the individual. The information can also be used in assigning work to the individual. Dissociative Identity Disorder (herein referred to as DID) and Post Traumatic Stress Disorder (herein referred to as PTSD) are classified as mental disorders. The two have formed the basis of research for many psychologists. The psychologists have made efforts to identify the root causes, treatment, and diagnostic procedures associated with the conditions. According to Dr. Brad Wright (and as cited in Farrell, 2011), the two conditions are significantly different from each other. Post traumatic stress disorder develops when an individual is exposed to any form of psychological trauma. Dissociative identity disorder is known by several other names. One of them is â€Å"Multiple Personality Disorder†. The condition is associated with individuals who exhibit two distinct personalities. It is characterised by forgetfulness or amnesia (Shettleworth, 2010). In this essay, the author will analyse the two conditions, comparing and contrasting their various aspects. The author will focus on the similarities and differences between the conditions’ etiology, diagnosis, and treatment. The Etiology of DID and PTSD: A Comparison Etiology of DID Etiology is the study of the origin and cause of a given phenomenon (Overskeid, 2007). It is commonly used in medicine to determine why and how things take place. The concept aims at providing a mythical explanation for a certain condition or phenomenon.Advertising Looking for essay on psychology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Over the years, many researchers and philosophers have come up with various possible causes of dissociative identity disorder. However, most are in agreement that the disorder is brought about by maladjusted r eactions to trauma. Such trauma is in most cases linked to childhood physical and sexual abuse (Hergenhahn, 2005). Most individuals suffering from this disorder had a traumatic experience in their childhood. Neglect and lack of parental care are largely associated with the disorder. Individuals exposed to extreme physical abuse in the past tend to be violent and brutal in later life. Psychologists associate this phenomenon with attempts by individuals to forget their past miseries. The failure to forget leads to frustration, which is expressed through acts of violence and brutality. Individuals who were exposed to acts of violence in the past are likely to try and expose others to similar conditions. The attempt explains the rising cases of violence in the society. Research has shown that criminals suffering from dissociative identity disorder expose their victims to ordeals that are similar to those they were exposed to in the past. Such developments give rise to a cycle of crime a nd violence, which turns victims into offenders. Self destructive behaviours have also been identified as possible causes of the disorder (Pinel, 2010). Individuals exhibiting such traits tend to be violent towards themselves and towards others. Etiology of PTSD Post traumatic stress disorder develops after an individual is exposed to an event associated with intense fear, horror, and a sense of helplessness (Reisner, 2005). However, psychologists have identified other possible causes of post traumatic stress disorder. They include past life experiences and inherited traits, such as individual personality. Individuals who had traumatic experiences in their past make the bulk of patients diagnosed with this disorder. Personality aspects that may influence the individual’s susceptibility to the disorder include, among others, temperament and ability to deal with stress. Regulation of hormones and such other chemicals as adrenaline by the brain is also associated with the condit ion. Exposure to risk factors is another possible cause of post traumatic stress disorder. Such exposure explains why many soldiers and people living in war torn areas are more likely to suffer from post traumatic stress disorder compared to other individuals.Advertising We will write a custom essay sample on Comparison of the Etiology, Diagnosis, and Treatment of DID and PTSD specifically for you for only $16.05 $11/page Learn More There are several similarities between the etiologies of the two psychological disorders. For example, both conditions are associated with past traumatic experiences. Individuals suffering from either of the two conditions are likely to have witnessed traumatic events in their life (Carver Scheier, 2004). Individuals react variously to such traumatic events. As a result of this, some of the individuals exposed to the traumatic events may fail to develop the condition. For example, those suffering from dissociative identity diso rder are violent towards other people. On the other hand, those suffering from post traumatic stress disorder live in perpetual fear of being abused or experiencing the traumatic events again. Diagnosing DID and PTSD: A Comparison Overview In most cases, individuals suffering from these disorders are unaware of their condition. It is also hard for family members and the society at large to diagnose the disorders. The inability to diagnose is attributed to the fact that the effects of these disorders are mainly psychological. As such, it is not easy to point out the characteristics. The case is different for other disorders, whose effects are expressed physically (Gelder Geddes, 2005). In most cases, the individual is not aware of their condition when they seek medical assistance. Diagnosing DID To diagnose dissociative identity disorder, the psychologist needs to conduct a thorough psychological examination of the patient. A medical examination is necessary to determine whether the patient has any physical disorders that may explain their symptoms (Glaser Strauss, 2005). Examinations are carried out through oral interviews or questionnaires prepared in advance. Hypnosis or drugs are also used to make it easy for the patient to reveal personal information to the doctor (Barlow Durand, 2011). In most cases, patients complain of amnesia. The individual is unable to remember events that took place within a particular period of time. They also suffer from memory loss. In extreme cases, the patient may forget about close friends and family members. The individuals are depressed and may exhibit suicidal tendencies in extreme cases (Ron, 2008). In addition, some patients diagnosed with dissociative identity disorder complain of either audio or visual hallucinations.Advertising Looking for essay on psychology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Diagnosing PTSD To diagnose post traumatic stress disorder, the professional needs to take into consideration the signs and symptoms exhibited by the individual. Patients are asked to explain their signs and symptoms. They try to explain what the signs are, the time they occur, and their intensity (Reinders, 2008). Individuals are also required to narrate the events preceding the symptoms. A patient has to meet a set of pre-defined criteria before the professional comes to a conclusion. Diagnosing post traumatic stress disorder and dissociative personality disorder calls for a series of psychological and medical assessments. Assessments are carried out orally or through the use of a questionnaire. Examinations to check for other medical problems are carried out to ensure that the correct diagnosis is made (Boysen, 2011). Treating DID and PTSD: A Comparison Treating DID calls for the combination of various states of personality (Stern, 2012). Interaction between the different persona lities helps the person to function normally. Drug therapy is used to relieve such symptoms as fear, anxiety, and depression. Psychotherapy is considered as emotionally painful. Individuals undergoing therapy experience emotional crises especially when recalling traumatic memories during therapy sessions. Hypnosis is also applied in therapy. Therapy sessions take place over a long period of time, usually over 3 to 6 years. Individuals are treated for other serious health problems that are exhibited, such as drug and substance abuse. Treating PTSD aims at helping individuals gain control over their own life. Individuals suffering from the disorder are advised to accept their condition. They are also empowered to cope with stress and such other phenomena. Unlike dissociative personality disorder, treating post traumatic stress disorder requires a combination of drug therapy and psychotherapy. There are various forms of drugs administered to those suffering from the disorder. They incl ude antipsychotics, antidepressants, and prazosin (Spiegel, 2006). Each of these drugs has a particular function. In psychotherapy, various interventions are used. The interventions include cognitive therapy, which involves empowering the individual to perceive things accurately to reduce trauma. Cognitive therapy is used together with other interventions, such as exposure therapy. The latter encourages the patient to face or confront the situations that scare them the most (Ross, 2009). Other interventions, such as eye movement desensitisation and reprocessing therapy, help the individuals in processing traumatic memories. There are obvious similarities between the treatment procedures for the two disorders. In both cases, the doctor attending to the patient aims at reducing the effects of the trauma (Farrell, 2011). In addition, treating the two conditions involves psychotherapy. A close relationship between the patient and the doctor in-charge must be maintained. The aim here is to increase the efficiency of the therapy sessions. Conclusion Psychology is a field of study dealing with human behaviour and brain functions. The discipline involves the assessment of such human characteristics as perceptions and emotions in efforts to explain individual actions (Singh Chakrabarti, 2008). Psychology has helped in diagnosing and treating various mental disorders, among them post traumatic stress disorder and dissociative identity disorder. Many people suggest that DID and PTSD are the same. However, significant disparities exist between the two with regard to etiology, diagnosis, and treatment. But there are also similarities between the two conditions. For example, the two disorders are associated with past traumatic experiences. References Barlow, D. H., Durand, V. M. (2011).
