Case Petroil

In one of Its first projects, the OLL exploration company Petrol was engendering two sites for two 011 exploration wells. Only one may be punctured. The cost of drilling the Site Numerous 1 was $ 100,000. Preliminary geological data indicated that the well could be dry, or be of low productivity or be highly productive. He had signed a contract with a development company to buy the site if a well by drilling success you had. The buyer would pay $ 250,000 for a well of low productivity and $ 600,000 for high productivity well.If the well was dry, Petrol lose $ 100,000 of the cost of drilling. By that time, the company geologist,Jane Goodwill, was unsure about the existence of a structural dome that site. A dome structure is a kind of anticlines (geological rock deformation formed as a curved folds as strata tectonic stress resulting from various types) raised to a certain depth by the accumulation of oil and the increase of the pressure produced by the natural gas . Structures are ide al for the accumulation of oil. She assigned a probably of 0. 6 to the existence of a structural dome.Their assessments for dry, low, or high productivity wells were conditioned to geological structure. Table 1 shows the odds by estimated conditions. The geologist would ether give the information in this way though as she said, â€Å"we will never know for sure if there is a structural dome, up to drill. † TABLE 1 Geological structure Well With No Doom Doom Dry 0. 60 0. 85 Low 0. 25 0. 125 High 0. 025 0. 15 1. 00 1. 00 Furthermore, the site No. 2 was quite different, the area had been thoroughly examined using seismic testing and core samples.A core sample Is a method directly by taking witnesses or cores (cores), collect rock samples taken within drill pipe, In which you can perform direct measurements of the petrochemical characteristics of the geological formation. There was almost certainly oil. The geologist assigned a probability of 0. 8 of finding oil there. The drawba ck to this place was that drilling costs were high, $ 200,000, and if oil is found, the well would be low productivity of oil. A contract was also signed with the same development company to buy the well of low production at Site No. 2 for $ 250,000.To help decide between the two sites, each drill site. Using the decision tree diagram A decision tree diagram should be developed for this problem using the concepts and the necessary rules. You must specify the uncertain events that will be revealed eased on each decision. The random variable of interest is the net contribution can be calculated at the end of each alternative or branch of the decision tree. Therefore in the branches of the diagram decision alternatives were presented with their respective probability and net contribution as a gain or loss. The decision alternatives with uncertain probabilities for drilling Site No. Events are available and would be appropriate to show them on the decision tree diagram (see Annex 1). Wh at would be the likely alternatives Drilling Site Number 1? They are not available erectly. We know the odds of having high, low or that the well is dry productivity. However, we can adjust the chart for evaluation inserting another uncertain event as the geological structure (with or without dome). By including this â€Å"extra† node, the description of the branches of the decision tree will expand to calculate the return (you only need dry, low or high to calculate the net contribution). Now include the status of the geological structure.With the expanded tree diagram decision is straightforward to calculate the probabilities required by the president of the many. Therefore, this problem has to insert the â€Å"additional† uncertain event (geological structure) so that the probability can be calculated. The uncertain event should be displayed in the diagram to have an observable result where not only the state of well productivity, but also the state of the underlyin g structure is found. Addition should be included because the geologist of the company wanted to use it as a basis for probabilistic assessments to the president of the company.

Multicultural Literature Essay- Eleithia Essay

Author, Alice Walker’s, Elethia, is a story of young Elethia who struggles to overcome a legacy of passivity, marginalization, inferiority, and misrepresentation of the Negro. To define her own identity she must break free and simultaneously hold on to the central figure that causes her to doubt her identity. Uncle Albert is a symbol of racism and the blindness that oftentimes presents itself within the Negro culture. There is a quote given by the late Dr. Martin Luther King, Jr., â€Å"there are many Negros who will never fight for freedom, but will gladly accept it when it comes!† Dr. King’s remarks are favored by me in the fight against racism and I understand it to mean this. That while segregation, impartiality, brutality and blatant disrespect are present, there will always be a certain percentage of people, belonging to an oppressed culture, who will idly sit by and accept the countless improprieties set before them while others continuously fight to break down the walls of bigotry. In the town in which Elethia made her home, Uncle Albert had been a fixture in the window of the Old Uncle Albert’s restaurant for good length of time. So long that some of the old-timers, who had known Uncle Albert before his murder, were victims of fading memories, â€Å"perhaps both memory and eyesight were wrong (Brown p.307).† As a humanist, I am annoyed that the story is absent, perhaps accidentally or possibly on purpose, that not one member of the African American community protested or took any actions to give Uncle Albert’s likeness a release. I understand fear. The fear of retribution and death at the hands of white supremacists, however years, an entire generation in fact, had passed and Uncle Albert’s remains still stood smiling in the white-only eatery. Since slavery religious instruction was aimed â€Å"to inculcate meekness and docility (Aptheker 122).† What about after the doors  of the church were closed? Throughout the short story, there is no mention of a revolutionary plot or rebellion by any one person or persons of the community. Elethia, young and still not sure of who she was, made the horrific discovery that Uncle Albert was stuffed as if he were and animal. At that moment, she along with her friends made the conscious decision that smiling Uncle Albert had to be excluded as a fixture in a plated glass window in order to give dignity to the Negro culture. I am a firm believer in non-violence but only when you are dealing with people who share the same view of non-violence. The story does not give the reader any hint that there was a rumble from the community of Negro people at a time when a loud noise should have sounded off. At a time when the Civil Rights Movement was in its infancy, the passiveness of the entire African American community of the small southern town gave credence to the myth of the docile Negro. Throughout American history, any person or persons of the American society, whom skin is deemed to be colored has been marginalized since he has placed his foot on American soil. The Negros place in society has been viewed as less important than those of his white brethrens. In Elethia, a young black boy’s privates were left nailed to a post for the town’s people, which included blacks and whites to see. I will take this crude act and look at in two ways to support my theory of marginalization: the first angle will be taken from a white societal viewpoint in that a young Negro boy is not looked upon as a human being. He is simply a person of color who is absent of pathos, and intellect. His status in the general public is placed the lowest echelon on the societal chain, therefore he does not warrant the right to be buried properly in a grave. The act of inhumanity can secondly be viewed by the African American community as an act of intimidation by the oppressor to furt her propel the theory of marginalization and minimize their self worth as citizens of a so called pluralist society. This marginalization theory leads to societal exclusion, the act of leaving one social class at a disadvantage while elevating another social class to point where there becomes a false sense of superiority. This false sense of superiority can and will result in inferiority, a mental prison. The bedrock of inferiority, that is the views that white America or Americans  have toward their opposites, who are black Americans derived from the words set forth by one of our founding fathers, Thomas Jefferson, in his Letters to the State of Virginia. In its fourteenth query he describes what he perceives the Negro to be: â€Å"The negro differences which are physical and moral. The first difference which strikes us is that of colour. Is it not the foundation of a greater or less share of beauty in the two races? Are not the fine mixtures of red and white, the expressions of every passion by greater or less suffusions of colour in the one, preferable to that eternal monotony, which reigns i n the countenances, that immoveable veil of black which covers all the emotions of the other race? Add to these, flowing hair, a more elegant symmetry of form, their own judgment in favour of the whites, declared by their preference of them, as uniformly as is the preference of the Oranootan for the black women over those of his own species. The circumstance of superior beauty, is thought worthy attention in the propagation of our horses, dogs, and other domestic animals; why not in that of man? Besides those of colour, figure, and hair, there are other physical distinctions proving a difference of race. They have less hair on the face and body. Perhaps too a difference of structure in the pulmonary apparatus, which a late ingenious (1) experimentalist has discovered to be the principal regulator of animal heat, may have disabled them from extricating, in the act of inspiration, so much of that fluid from the outer air, or obliged them in expiration, to part with more of it. They seem to require less sleep. A black, after hard labour through the day, will be induced by the slightest amusements to sit up till midnight, or later, though knowing he must be out with the first dawn of the morning. An animal whose body is at rest, and who does not reflect, must be disposed to sleep of course. Comparing them by their faculties of memory, reason, and imagination, it appears to me, that in memory they are equal to the whites; in reason much inferior, as I think one could scarcely be found capable of tracing and comprehending the investigations of Euclid; and that in imagination they are dull, tasteless, and anomalous. It would be unfair to follow them to Africa for this investigation. We will consider them here, on the same stage with the whites, and where the facts are not apocryphal on which a judgment is to be formed. It will be right to make great allowances for the difference of condition, of education, of conversation, of the sphere in which they move. I find that a black had uttered a thought above the level of plain narration; never see even an elementary trait of painting or sculpture. In music they are more generally gifted than the whites with accurate ears for tune and time, and they have been found capable of imagining a small catch (2). Whether they will be equal to the composition of a more extensive run of melody, or of complicated harmony, is yet to be proved. Misery is often the parent of the most affecting touches in poetry. — Among the blacks is misery enough, God knows, but no poetry. Love is the peculiar ;oestrum of the poet. Their love is ardent, but it kindles the senses only, not the imagination. Religion indeed has produced a Phyllis Whately; but it could not produce a poet (Jefferson).† Mr. Jefferson claims that the Negro is less beautiful than whites and that Negro man desires the free flowing long hair of the white woman over that of the Negro women. He says the Negro lacks intelligence, so much so that he doesn’t know when to lie down when his body calls for rest. The Negro is quite capable of imagining, but lacks the skill to produce works of art. The Negro has a foul odor. The Negro has a different pulmonary apparatus than that of the Anglo- man. Thomas Jefferson’s query is the foundation in which biased racial views were built upon and the home in which inferiority breeds. In the context of Elethia, she was not allowed to eat in the white-only establishment, however, she was permitted to take a menial position as the kitchen help. This added to her as well as the other Negro worker’s persistent feelings of inadequacy. â€Å"Not good enough to eat here but good enough to clean your slop jar (Anderson, 323)!† She was able to look but not touch. In Walker’s, Elethia, Uncle Albert not only was he angry when he and his family learned that slavery had ended a decade prior to his knowledge. He felt inferior because due to the oppression of his owner he became an paradigm of Thomas Jefferson’s statement â€Å"the Negro lacks intelligence (Jefferson query XIV).† Uncle Albert did not possess the skill or intellect that kept him ignorant to the laws and abolishment of slavery. His lack of knowledge perpetuated the feelings of inferiority. Another example of inadequacy came to pass when Elethia learned the truth of Uncle Albert’s remains. She saw this as a mockery and another disregard for a Negro life. She viewed Uncle Albert’s standing in the window as a shadow  of racism. The plate glass window holding Uncle Albert’s smiling remains is a misrepresentation of the African American Community. He was placed there like a caricature advertisement to entice patrons to dine at the all white faci lity where they will be handled with the utmost care by our friendly waiter, Uncle Albert. First, the African American old-timers in the text make it clear that Uncle Albert was nobodies Uncle, â€Å"and wouldn’t sit still for anyone to call him that either (Brown 308)†. Second he never smiled, in fact the text leads the reader to believe that Uncle Albert was a bit of a surly man, who was filled with a lot of anger and nowhere to extinguish it. If occasionally he managed to open his mouth in the form of a smile, there would be vacancies where teeth had once dwelled. When the old timers, who were members of the African American community, talked about Uncle Albert, they used his name Albert Porter. This momentarily afforded a black man a little slice of dignity, a representation of a man lacking inferiorities. With the removing of the young black boy’s genitals from the post, Uncle Albert gave the boy and his family a slice of the same pie of dignity; a slice that represented that someone showed compassion for another human soul. In my opinion, the placing of Uncle Albert in the window of the segregated eatery, it says that the Negro will always be less than, enslaved, and subservient in life or in death so he should â€Å"grin and act like a nigger (Brown 309).† When in slavery, Uncle Albert was beaten severely because his oppressor wanted him to forget his past. This was a blatant misrepresentation of him and every black person housed between the walls of racism. Uncle Albert refused to forget. His refusal brought him additional pain and suffering. Stubbornness would not allow him to forget and succumb to the smiling happy Negro. In finding ones identity, one oftentimes has to look at others. Noted scholoar, WEB DuBois explore the Negro culture. In regards to identity he tells us about the double consciousness. â€Å"This double consciousness is a psychological sense experienced by the African Americans whereby they possess the national identity, â€Å"an American,† within a nation that despises their racial identity and that blacks see themselves only through the eyes of white Americans to measure intelligence beauty, and a sense of self-worth by standards set by others (DuBois 4).† Young Elethia was coming of age and her inquisitive nature uncovered truths and these truths led to more inquiries. Who am I? Who is Uncle Albert? Am I my community? Am I Uncle Albert? Am I going to let someone who keeps my community in oppression define who WE should be? Between the lines of the text these questions rang out to me. The title of the short story is Elethia, which when you search for names for girls you find that Elethia means healer. Was Elethia taking on the role as healer for the entire African American community? Was she only there to heal the memory of Uncle Albert? In a search for Elethia’s identity, I think that maybe the author, Walker, purposely named her character Elethia as a subtle way to aide her in the restorative process against inequality. The removal of the symbol of pain weaved together with a mythological symbol that helps lessen the pain in order to make a society whole, is nothing short of genius. It not only helped in the formation of young Elethia it gave a self-esteem booster to the African American community. The absence of Uncle Albert in effect may have unmasked the veil in which W.E.B. DuBois says the black folk live under (14). Uncle Albert’s persona displayed in the window puts me in the mind of Aunt Jemima, a mammy black face figure, with a big smile, whom is overly obedient, and whose primary goal in life is to be happy and subservient to the Anglo community. This is viewed as a negative stereotype in the African American community, not just in the small southern town, but all over America. Due to the veil worn by the African American community, Aunt Jemima was accepted by the African American community before the veil was lifted. The Aunt Jemima persona was juxtaposed as to what Uncle Albert was in life. With him no longer in the window that element has disappeared and the Negro has the freedom to create his own identity. By removing him from the window and giving him a proper cremation, the ‘young self imposed civil rights activist/reconciliators of the community’ not only released him from the glass plated walls of slavery but they gave him a spiritual release to heal his soul and the souls of the community. Not only was Uncle Albert a remembrance of pain he became a commemoration of healing when Elethia along with her friends decided in an act to resist racism decided to free Uncle Albert it became a cleansing for the African American’s of the town. By keeping his ashes it was a reminder of the past; albeit a past Uncle Albert refused to forget. Uncle Albert was not allowed to be free, to go  off to college to be and do better things. He was trapped. Keeping his ashes was also a symbol of humbleness to not forget where you started from. Elethia saw change that disallowed her and her friends to become trapped. This change allowed members of the African American community everywhere to claim and create who they wanted to be for themselves, as well as their families. In Elethia’s travels in life she had ran into several Uncle Alberts and Aunt Albertas who were not permitted to exist (Brown 309). The African American individuals whom were not permitted to be seen or heard by means of oppression, or their own lack or inability to seek a better life. His ashes are a constant reminder of who she is now in the present, how far she has come, and how much further she needs to maintain the feeling of wholeness. Although Wikipedia is not a scholarly source, it gave me the definition of identity and I believe it is reasonably accurate. Identity is defined as sameness, or whatever makes an entity definable and recognizable. By transcribing the memory of Uncle Albert it did just that and also Elethia also created a legacy. This legacy that can be retold without censure or wrong misgivings which gives legacy gives the African American Community a place in history; a place that says yes our people do and did exist. In addition a legacy is about the way one lived or is living in hopes that the future outcome will have results greater than the past. Elethia’s legacy also provides the African American community with history that mirrors the way they look, traditions that existed, the way they speak, and the way they were forced to live. This culmination of factors adds to Elethia as well as the Negro community and adds to each ones identity. I once read somewhere that without a legacy the meaning of life is sometimes lost. Had some of the Uncle Alberts and Aunt Albertas in Elethia path lost their meaning of life and may that loss caused them to be blind? Maybe or maybe not, however one struggle to overcome the products of racism can definitely effect the way ones views himself. In conclusion a legacy can oftentimes become the catalyst that brings about social change and is a definite component of identity.

Freud, Adler and Jung: Founders of Psychoanalytic Research Essay

Introduction: There are three well-known influential thinkers who are considered to be pioneers in the field of psychology. It could be argued that without †¦. , the emergence of psychology as we know it might not have ever happened, at least in its present form. Freud is considered by his modern-day counterparts to be the founding father of analytic psychology, as he is the first to have come up with an albeit rudimentary, but nevertheless valuable model of the human psyche. Prior to his groundbreaking work, the nature of human consciousness was largely debated and theorized by medical doctors and theologians. Then there is Adler, (who was the first to have suggested the societal impact on emotions and thought processes and vice-versa, arguing that consciousness and culture have what could be termed as a symbiotic relationship. He emphasized, too, the importance of self-esteem and was the first to say that without a healthy self-esteem, an individual would develop an inferiority/superiority complex which would in turn affect many aspects of life. Last but not least, Carl Jung, who was a respected colleague of Freud in his earlier years, focused on the spiritual aspects of consciousness and saw the value it played on thoughts and emotions. We will explore in this paper the commonalities between these founding fathers of psychology as well as their differences, and explore the strengths in their theories as well as the weaknesses. By understanding the founders of this very subjective field of scientific thought, we can gain a better picture of how psychology has evolved over the years and apply it to our own research and studies. Sigmund Freud: According to Freudian theory, the consciousness is composed of three opposing forces: the id, the ego, and the superego. The id (Freud used the German term Das es) which consists of our instinct-driven behavior. Governed by what he termed the â€Å"Pleasure Principle†, It is largely pleasure-seeking: when we are hungry, we seek to obtain relief from these feelings by eating. Because the id is a self-gratifying drive, it can, according to Freud, cause problems if left unchecked, since the person would have absolutely no self-control and wouldn’t be able to exercise the self-discipline necessary to function in society. In accordance with what Freud calls â€Å"The Reality Principle†, The ego (das ich) copes with the limitations of reality by putting into place coping mechanisms when one’s basest needs cannot be fulfilled. For instance, it is the ego which represses the needs of the id by waking up early for work when the id tells us to sleep in late. The Superego (uber ich) tries to rule over the ego and id with moral principles which are both conscious and unconscious. It can be described as one’s religious convictions and moral principles. The Superego can override the ego and id when something must be done â€Å"for the greater good†, i.e. for moral reasons. Another Fundamental element of Freudian theory is his stages of psychosexual development, which categorizes each stage as follows: The oral stage where a child seeks comfort from suckling, the anal stage where the child is toilet-trained, the phallic stage where a child’s awareness of a penis (or lack thereof) plays a crucial role in early development, the latent period, and finally the genital stage. In each of these stages (aside from the latent stage where it is believed no crucial psychosexual development takes place) if there is a disturbance in normal development, a â€Å"fixation† can occur. For instance, if a child is weaned from breastfeeding too early, he or she can have an â€Å"oral fixation† which would manifest itself as nail-biting or smoking later in life. Last but not least, Freud was the first to propose that when we face situations we cannot emotionally handle, we have certain defense mechanisms such as repression, suppression, denial, displacement, sublimation, intellectualization, and rationalization, regression, and reaction formation. These mechanisms can be considered normal, especially during grieving periods. Much later, Dr. Elisabeth Kubler-Ross made shock and denial one of the first stages of the grieving process, and it has been well-documented that denial can be very common if not normal as long as it doesn’t become permanent. Defense mechanisms can become very unhealthy if they don’t eventually give way to directly coping with the emotions which are being denied or repressed. These defense mechanisms, in their most extreme forms can be very difficult to understand for those who haven’t shared the same experience. For example, it is very possible for a woman to be so deep in denial of a pregnancy that she will continue to menstruate up until the time of delivery. She could also attribute the normal symptoms of pregnancy with other possible explanations, i. e. morning sickness being stomach flu and the baby’s kicks being gas. A typical example of displacement can be seen with people who abuse animals or children. If a person feels they cannot express anger or aggression to a parent or significant other for fear of repercussions, they will channel the anger and direct it to the family pet or their child, who cannot fight back. Regression can be another common defense mechanism, and it usually happens when an individual is overwhelmed with anxiety and feels they cannot directly face the source of their emotions. A very common scenario is for an adult to remain in bed all day and sleep to avoid painful feelings shortly after a loved-one dies. Another example is when a child is afraid to attend school because of a bully, and becomes extremely clingy with the parent when he or she was very independent prior to the problem. Carl Jung. Jung and Freud became friends in 1906, after Freud had read some of Jung’s writings and invited him for a meeting in Zurich. Their first conversation was said to have lasted for 13 hours, with the two men exchanging ideas and elaborating on their theories. Freud saw Jung as somewhat of a protege, referring to Jung as his â€Å"crown prince and successor†. Their correspondence and friendship lasted six years, but Jung eventually expressed dissent with Freud over the role the unconscious mind played in human behavior. While Freud saw the unconscious as somewhat of a repository of repressed memories which could be manifested unbeknownst to the conscious mind, Jung believed that the ability to tap into the unconscious mind was possible and could contribute to emotional well-being. And while he agreed that it was important to understand past trauma and its influence on present behavior, he also believed that the future didn’t necessarily need to be determined by such things. The role spirituality played in his psychoanalytic theories also made him a pioneer in his own rite, though it was never something he and Freud could agree upon. Alfred Adler. Alfred Adler was also a contemporary of Dr. Freud and even joined his analytic society in 1902. By 1911 however, he too expressed dissent with many of Freud’s opinions and left to form his own society, the ‘Society for Free Psychoanalytic Research’. It can be reiterated that while he agreed with Freud that psycho-social development could be affected by influential factors beginning early in life, he came up with theories of his own which contrasted with those of his colleague. For instance, he believed that a child feels inherently weak around his or her elders, and strives to become superior to them throughout the course of early life. This term, known as â€Å"striving for superiority†, states that if the need for personal accomplishment and success is not met, an inferiority complex can develop, causing many other problems later on. He also proposed the theory that birth order plays a crucial role in emotional development. For example, he stated that an oldest child has it the worst, as he or she starts off having both parents’ unlimited attention and time. Later on after other siblings are born, an oldest child isn’t given the same amount of attention and is left to wonder why. Childhood neglect and abuse also have a profound impact on psychosocial development according to Adler, and numerous case studies continue to arise which prove his theory to be valid even today. Conclusion While many of the theories of Freud, Adler and Jung have been either dispelled or refined by case studies and discoveries in the field of neuroscientific research, there is no doubt they were pioneers in the field of psychology. Freud’s concepts of defense mechanisms have withstood the test of time even though his theories of psychosexual development have been outmoded, and Jungian psychoanalysis is still relevant today. Adler’s views on self-esteem and childhood development have been verified by clinical research, even if some of the finer points of his research had been discarded. While there is continued debate and new findings which will always create dissent and result in new discoveries related to psychology, it is certain that the work of these three early founders will remain significant for decades to come.

Making Connections Between Three Authors - Essay Example of new players, on a new playing field, developing new processes for horizontal collaboration—that I believe is the most important force shaping global politics and economics in the early 21st century (Friedman, 7).† Friedman also warns that Americans need to keep up, or get out of the game. â€Å"There is no sugar coating on this: in a flat world, every individual is going to have to run a little faster if he or she wants to advance his or her standard of living (Friedman, 10).† Still, some low-income groups of Americans are at a disadvantage and succumb to the â€Å"roundness† of the bygone American world. Though countries like China and India are exploding ahead politically and technologically, African Americans and people of color in the United States have little opportunity to do the same. According to Barbara Ehrenreich’s article â€Å"Maid to Order† and William Julius Wilson’s book When Work Disappears: The World of the New Urban Poor, the world is definitively not flat, but limited to the socio-economic imprisonment of the lower urban class. Both Barbara Ehrenreich’s article â€Å"Maid to Order† and William Julius Wilson’s book When Work Disappears: The World of the New Urban Poor show a rethinking of the mostly-optimistic approach Friedman has towards the â€Å"flat,† expansionist and technologically forward view of the world. â€Å"Maid to Order† discusses the trials and tribulations of being a maid, and the sorry, anti-feminist history behind the booming industry of domestic work. â€Å"In a society in which 40 percent of the wealth is owned by 1 percent of the households while the bottom 20 percent reports negative assets, the degradation of others is readily purchased (Ehrenreich, 1).† This degradation comes in the form of racism, sexism and classism that has been an American mainstay since the turn of the century. â€Å"So the insight that distinguished the more radical, post-Friedan cohort of feminist was that when we talk about

In conducting a Systemic desensitization for a survivor of 9/11, Cognitive behavioral therapy is highly recommended. This is a common type of metal health planning in which a psychotherapist in a structured way and holds a number of session with the patient. This process helps to make sense of the overwhelming problem by breaking it down into smaller parts (Coble 64). It will help the patient to see how they are connected and their effect. A situation, which is the problem this is closely followed by thoughts, emotions, physical feelings then lastly actions. The most effective treatment in this case is the flexible application of a manualized cognitive behavioral therapy. Treatment delivery ranges from about 12- 25 sessions. Relaxation is an imperative component of CBT. It deals with the process of learning about somatic cues, after which the body is taught to relax. In progressive relaxation, the patient first learns the relaxation skills and latter he and the therapist create the anxiety hierarchy. He is able to provoke the situation in a gradual process. He faces the situation progressively by developing a consistent paring of relaxation. Gradual desensitization closely follows. Virtual reality exposure has proved to more effective than mental imagery (Coble

Mobile Services Research Proposal Example | Topics and Well Written Essays - 2000 words

Mobile Services - Research Proposal Example Some of the services available on a mobile phone include voice call, text messaging, video conferencing, ring tones, weather, news, horoscopes, music, emails, mobile internet, video camera, Bluetooth, MP3, still camera, WiFi, mobile television, gaming, Microsoft Office programs, multimedia messaging including pictures and photos, data access and transfer with personal computers, and a number of other value added features. Many people and organisations have carried out a number of researches to find out the impact of new and varied mobile services on users. These market researches are particularly important when new products and services are to be produced. Nielson company has announced that they will conduct a research study to find out the most frequently used mobile phone functions (Balan, 2007). The purpose of this research is to identify the areas which appeal to mobile phone users, and hence target efforts to develop new and novel ways to enhance services in these areas. For instance, if consumers prefer to use text services over watching mobile television; the companies can enhance text messaging option by providing word editor etc. on their mobile phones; and pull back from providing mobile television services since these do not attract consumers' attention. As Balan (2007) quotes, "Reliable and accurate measurement of mobile consumers will enable advertisers to properly evaluate the mobile ma rketing opportunity. Independent measurement of the cross-media behavior of the growing mobile audience will support and accelerate the evolution of mobile media business models" (Jeff Herrmann - Vice President of Nielsen Wireless). Despite the fact that an increasing number of people keep and use mobile phones, there are groups of people who think that using mobile phones in public is annoying and should be discontinued. Monk, Carroll, Parker, and Blythe conducted a study in 2004 on this topic and the results show that many people believe that face to face meeting is much more effective than mobile phone calls. In addition, the research revealed that people generally disapprove mobile phones ringing in churches, trains, funerals and other events and places of such nature. It is generally treated as unethical as per the research (Monk Carroll Parker Blythe, 2004, p.33-41). In addition, there are some controversies regarding mobile phone use, with regard to medical and health issues. Many people have raised voices against mobile phone usage claiming that it results into brain cancer and other medical disorders, especially in children. BBC News (2000) published a story regarding the cries against mobile phone usage in children, and provided results of various researches on the topic. The summarised results indicated that although there were no proven medical problems from the use of cellular phones, yet children should be kept away from mobile phones until absolutely necessary. This and similar news items and researches have contributed a great deal in reducing the number of mobile phone users and have even more affected the use of other mobile services besides voice calls and text messaging. The recent introduction of third generation (3G) mobiles has revolutionised the way mobile communication used to work. 3G mobiles provide high data speed, better voice and data transfer quality and high availability. However, as per the resear

Art History through the 19th Century (Final Compare and Contrast Term Essay

Art History through the 19th Century (Final Compare and Contrast Term Paper) - Essay Example He was born in Flanders. Rubens was raised Catholic, which was reflected in many of his paintings (Belkins, 11). The environment Rubens grew up with a Calvinist father and mother. Since Rubens father was away at King William of Orange I, his mother taught him to be a Catholic after moving to Antwerp (Belkins, 16). The anti-Protestant environment in Flanders caused this move. After studying under Titan, Rubens really came into his own. His sublime portraits dealt with the ugly subjects many would not touch. In comparison, Delacroix was a French Romantic painter. He was trained as a classical painter at the time. After visiting England, Delacroix started illustrating different works of writing. His clients included Shakespeare and Lord Byron. Both Rubens and Delacroix were affected by royal courts. Rubens was affected by William of Orange I and Delacroix was affection by the Neapolitan royal courts. Delacroix was influenced by Rubens artwork. Since Ruben was a Baroque painter, his paintings including Allegory of the Outbreak of War, is an emotional religious generated piece of art. Since being a Catholic, Ruben’s paintings had symbolism of right and wrong. Even though it might seem blasphemous to paint pictures of ancient gods, but the painting was an allegory. Since it was popular under the Catholic Medici’s to create works under the Baroque styles, Ruben fulfilled this goal with most of his work. Delacroix, on the other hand, was a painter from the Romantic era, which means Death of Sardanapalus was in that style. The painting was based on a work by Lord Byron. The sublime content of the painting was typical of the Romanticism style. The nationalism of Sardanapalus killing himself for losing in a military battle is also a factor in a Romanticism painting. Monsters, a broken lute, Mars’ feet on a book, and the women all have sorrowful looks and torn veils, all signify the horrors of war (Cooper). The allegory

Social Service Work Essay Example | Topics and Well Written Essays - 250 words

Social Service Work - Essay Example One type of work that is associated with the field of serving aged people is conducting educational programs for the elders. Such kind of programs helps the elderly people to be interested in motivating themselves and to be up to date with the current trends in the society. Most often, their education is overlooked by the society and no such programs are conducted. These workers help them by conducting programs of knowledge sharing and make them believe they have many more steps to walk in their life. One example program of educating the old people is teaching them about internet. Many of the older generations are unaware of the importance of internet in their day to day life. Teaching them about internet and its usage would help them to get their required information easily and help them spend their time leisurely. Another program that could be used as part of learning is educating the elders about the social networking sites. This would greatly help them to keep in touch with their closed ones and to interact more with the society, right from their home. There are several other opportunities similar to education programs like counseling, health care, law issues etc.

LAW OF CONSUMER PROTECTION Essay Example | Topics and Well Written Essays - 2500 words

LAW OF CONSUMER PROTECTION - Essay Example Then the consequences for recovering and claiming damages with respect to the sale of goods under a hire purchase agreement will be discussed. The first problem of note appears to be a case of misrepresentation. Keith, the sales agent with whom Vic and Gaynor negotiated the purchase of the sofa from Funky Furniture with, represented to the couple that the sofa would fit through the internal doors of their home. This concern appeared to be a pre-condition of the contract for the sale of the sofa. Having convinced the pair that the sofa would fit through the internal doors of their home, Vic and Gaynor decided to enter into a hire purchase agreement for the purchase of the sofa. Under the law of contract, misrepresentation arises in situations where there is a communication of false facts which have the effect of inducing the party who is receiving the false representation to enter into legal obligations.1 A Misrepresentation can be made either negligently, fraudulently or innocently. The extent of the applicable remedies in respect of misrepresentation will depend on the type of misrepresentation made.2 In a typical case where misrepresentation is substantiated, the innocent party can if he/she desires, rescind the contract and/or make a claim for concurrent damages.3 Vic is required to prove that she relied on Keith’s misrepresentation or that she was induced to enter into the contract because of Keith’s misrepresentation.4 If however, Vic relied on her own judgment with respect to the sofa being able to fit into the internal doors of her home she cannot claim that she relied on Keith’s misrepresentation.5 On the facts of the case for discussion however, it appears that Vic did not rely on her own judgment since she questioned whether or not the sofa would fit into the interior doors. It was only after Keith assured her that it would that she entered into the contract for the purchase of the sofa.

Global Financing Essay Example | Topics and Well Written Essays - 1000 words

Global Financing - Essay Example Countertrade is classified under five divergent types namely; barter, counter purchase, offset, switch trading and buyback. There are five distinct types of countertrade -- barter, counter purchase, offset, switch trading, and buy back. Under this essay, we will focus on the meaning and the significance of each type in the international trade scenario. Barter can be defined as a direct exchange of goods and services, or both, between two parties without a cash transaction. It involves exchange of goods for goods and does not involve cash payments or receipts. Although in theory barter appears to be the simplest arrangement, in practice it is not commonly applied or practically implemented. It can be said that the expansion of bartering in the US is mainly because of barter companies or barter exchanges. According to popular estimates, there were roughly 600 barter exchanges among which 500 acted as clearinghouses for the exchange of goods and services between their clients and 100 were corporate trade brokers that exchange trade credits for assets, and goods and services so as to make it a part trade and part cash transaction. In a manner, barter dealers or barter exchanges facilitate a common platform upon which members exchange goods and services either through pure barter or through mixture of barter and cash. The barter exchange generates its profits from membership and renewal fees and from certain commissions which are based on a percentage of the gross worth of each operation. The fees usually range between 5 to10 percent. Under certain arrangements, some barter exchanges also charge a monthly administrative fee. The most significant purpose of a barter exchang e is to match the needs of potential traders. Counter Purchase Counter purchase is a form of mutual buying agreement. It occurs when a firm agrees to purchase a certain amount of materials back from a country to which a sale is made. Typically, there will be two distinct contracts. One of them will relate to the sale of goods/services by the trading company for which it will be paid a specified amount of hard currency. The other form will require the trading company to spend some proportion of this revenue to buy goods from a list provided by the importing country. The counter-purchase may vary in value between 10 and 100% of the original export order. The imports bought require not be related in any way to the goods/services exported. Generally, there is a specific time period (normally three years) within which the counter-purchase must be made. Thus, in this form of counter-trading (unlike pure barter), exports only partly finance the purchase of imports. In fact, they simply help balance costs on imports at a later date. In this manner, a co unter-purchase transaction is not undertaken because of a lack of convertible currency or incapability to obtain credit. Nevertheless, it has often been used by planned economies as a tool for scheming foreign trade and ensuring that exports balance imports. Offset Offset is similar to counter purchase since the exporter is required to purchase goods and services with an agreed percentage of the proceeds from the original sale. The main difference is that the exporter can fulfill this obligation with any firm in the country to which the sale is being made. Certainly, its importance appears to be growing fast. It involves an agreement under which an exporter integrate into his final product, along with certain components and

Does Successful Internal Communication at the Time of Change Result in Coursework

Does Successful Internal Communication at the Time of Change Result in a Motivated Workforce - Coursework Example Information Technology provides several options for this. E-mails, intranets and other innovations help in meeting the high demand of communication during such time of alteration within the organization (Wojtecki and Peters, 2000). Face to face communication also might help a lot to sort out the differences. There have been mostly separate studies about leadership and grapevine communication. According to McKenna (2000), leadership is an art that can get the optimum work required for the organization. The leader also communicates the organization's goals to his team members. He does not discuss the communication that is more important between the leader and the team and the effectiveness when such communication occurs in an informal way that leads to more interaction and hence develops a bond with each employee and all together leads to commitment.  Most of the studies so far have taken the formal side into consideration. In Contemporary issues in management and organizational beha vior (Peter, Poole and Jones, 2005), the whole cycle of Team-leadership has been portrayed in analyzing group decision- making and learning. Later, a global perspective has been given. According to Robert E. Hoskisson, â€Å"Organisational Structure specifies the firm’s formal reporting relationships, procedures, controls, and authority and decision-making processes.† (Hoskisson, 2008, p.100) This accrues to the basic framework of assigning roles, allocation of resources and provides a basis for cooperation, coordination, and communication among the organizational hierarchy. (Hoskisson, 2008). Harris and Hartman discuss the problems of Grapevine. According to them, it is not a dependable source and cannot provide full information and may be distorted. (Harris & Hartman, 2002).  

Pythagoras Theorem and Financial polynomials Essay Example for Free

Pythagoras Theorem and Financial polynomials Essay Ahmed and Vanessa have interest in locating a treasure, which is buried. It is my responsibility to help the two locate it. First, I will help them locate it by the use of Pythagorean quadratic. As per Ahmed’s half, the treasure is buried in the desert (2x + 6) paces form the Castle Rock while as per Vanessa’s half she has to walk (x) paces to the north then walk (2x + 4) paces to the east. According to the Pythagorean theorem, every right angled triangle with length (a) and (b) as well as a hypotenuse (c), has a relationship of (a2 + b2 = c2) (Larson Hostetler, 2009).                  In Ahmed and Vanessa’s case, I will let a=x, b =2x+4 and then c=2x+6. To follow, will be my efforts to put the measurements above into the real Pythagoras theorem equation as follows: X2+ (2x+4)2=(2x+6)2 this is the equation formed out of the Pythagoras Theorem X2+42+16x+16 = 42+ 24x+36 are the binomials squared x2 42 on both sides can be subtracted out. X2+16x+16 = 24x +36 subtract 16x from both sides X2+16 = 8x+36 now subtract 36 from both sides X2-20 = 8x X2-8x-20=0 I will use to solve the function by factoring using the zero factor. (x-) (x+) the coefficient of x2 Application and selection from the following (-2, 10: -10,2: -5,4; -4, -5) In this case, it seems that I am going to use -10 and 2 is as per how the expression looks like this (x-10)(x+2)=0 X-10=0 or x+2=0 creation of a complex equation x=10 or x=-2 these are the two probable resolutions to this equation.                     One of the two calculated solutions is an extraneous solutions, as it do not work with such sceneries. The remaining solution I only have is (X=10) as the number of paces Ahmed and Vanessa have to accomplish to find the lost treasure. As a result the treasure is 10 paces to the north 2x+4 connect the 10, now its 2(10)+4=24 paces to the east of Castle Rock, or 2x+6= 2(10)+6=26 paces from Castle Rock. Financial polynomial                   For the case of financial polynomials, I have first to write the polynomial without the parenthesis. Following the above, I have to solve for p= 2000 + r = 10% for part A and then solve for p= $5670 + r = 3.5% for part B, without the parenthesis as follows: P + P r + P r2/4 (the original polynomial) to reach this I followed the following steps: (1 + r/2)2 This is because it looks as if it is foil P(1 + r/2) P (1+r/2)(1+r/2) After the two equations I combine like terms. Because I am multiplying by 2 on r/2, it cancels out both 2’s and I then get left with is r as follows; P(1+ r/2 + r/2 + r2/4) P(1 + 2(r/2) + r2/4) I then write in descending order (P + Pr + Pr2) To solve for P=2000 and r=10% the following follows; P + Pr + Pr2/4 2000 + 2000 Ãâ€"(0.10) +2000Ãâ€" 0.1024 2000 + 200 + 5 = $2205 P(1+ r/2)2 2000Ãâ€"( 1 + .10)2 2000Ãâ€"(1.05)2 2000Ãâ€"( 1.1025) = $2205 For part B I will solve for P=5670 and r= 3.5% P + Pr + P Ãâ€"(r2/4) 5670 + 5670Ãâ€" (0.035) + 5670 Ãâ€" 0.0352 5670 + 198.45 + 1.7364375 = 5870.1864375 This is approximately ($5870.19) The problem 70 on page 311 has the following steps; (-93 + 32 – 15x) à · (-3x) The Dividend is (-93 + 32 – 15x), and the Divisor is (-3x). The Dividend is (-93 + 32 – 15x), and the Divisor is (-3x). -93 + 32 15x -3xAfter I divide -9 by -3 which equals +3. The x on the bottom cancels the x from the top. -93 + 32 – 15x -3x -3x -3x -9* x*x* x I am now left with 32 for the first part of the polynomial. -3 * x -9*x *x * x -3 * x I first divide 3 by -3, which equals -1 and the x from the bottom cancels out one of the x’s from the top. -93 + 32 – 15x -3x -3x -3x 3 *x *x At this point I am left with -1x, which simplifies to just –x, as the second part of the polynomial. Then -3 *x 3 *x * x -3 * x Then I divide -15 by -3, which equals positive 5, and the x on the bottom cancels out the x on the top, so you do not have any x’s to carry onto the answer of the equation. -93 + 32 – 15x -3x -3x -3x -15 *x At this point I am left with only 5 for the last part of the polynomial, and the answer is 32 – x + 5. -3 * x -15 * x -3 * x                   The negative sign from the -3 x changes the plus sign in the equation to a minus sign, it changes the minus sign to a plus sign in the final answer, and the equation is in Descending order.

LED TV Technology Overview Engineering Essay

LED TV Technology Overview Engineering Essay This paper discusses the Light Emitting Diode (LED) technology and the impact it shall have on television applications. The paper highlights the advantages and challenges for these applications and explore the specific advantages that LED technology has for DLP (Digital Light Processing) product applications. Introduction With a wide variety of applications, the LED has become a pivotal illumination technology.Since their initial invention, LEDs have been used in many diverse applications such as watches, calculators, remote controls, indicator lights, and backlights for many common gadgets and household devices. The technology is advancing at a rapid pace and as the brightness and efficiency of LEDs increases, new applications continue to emerge. From the early 1900s, scientists have been discovering ways to generate light from various materials. In 1907, Henry Joseph Round discovered that light could be generated from a sample of Silicon Carbide (SiC). For the next 50 years, scientists continued to discover the light emitting properties that exist with some compounds. In the 1950s, studies around the properties of Gallium Arsenide (GaAs) paved the way for the first official LED discoveries that soon followed.1 LED research began in the early 1960s, primarily at Bell Labs, Hewlett Packard (HP), IBM, Monsanto, and RCA. Gallium-Aresenide-Phosphide (GaAsP) provided the basis for the first commercially available red LEDs in 1968 by HP and Monsanto. In the early 1970s, the use of LEDs exploded with new applications such as calculators and watches by companies like Texas Instruments (TI), HP, and Sinclair. Other applications such as indicator lights and alphanumeric displays soon became the mainstream use for LEDs and continued to be so for many years.2 LED Technology Background As the name implies, an LED is a diode that emits light. The diode is the most basic semiconductor whose purpose is to conduct electrical current with some form of controlled variability. The diode in its simplest form is comprised of poor conducting materials that have been modified (or doped) to increase the amount of free electrons that are available. High electron materials (referred to as N-type materials) are combined with low electron materials (referred to as P-type materials) to form a junction for these free electrons to flow. This junction is often referred to as the PN junction. An LED is a PN junction diode semiconductor that emits photons when voltage is applied. This process of photon emission is called injection electroluminescence and occurs when electrons move from the N-type material to fill the lower energy holes that exist in 2 the P-type material. When the high energy electrons fall into these holes, they lose some of their energy which results in the generation of photons. The materials used for the P-type and N-type layers along with the size of the gap between them determine the wavelength and overall energy level of the light that is produced. Many materials have been developed for manufacturing LEDs. Aluminum-Gallium-Arsenide (AlGaAs), Aluminum- Indium-Gallium-Phosphide (AlInGaP), and Indium-Gallium-Nitride (InGaN) are commonly used for present LED architectures. AlInGaP is typically used for Red and Yellow dies while InGaN is used for Blue and Green. These materials efficiently produce photons that have wavelengths in the visible spectrum. These materials in combination with new manufacturing architectures have enabled the production of very bright LEDs that are beginning to find their way into general lighting and automotive applications. Some architectures have begun utilizing additional phosphor compounds to generate white light and are now beginning to compete with common incandescent and fluorescent lighting with much lower power and much longer lifetimes. The worldwide production of LEDs has risen to about 4 billion units per month. Manufacturing in Taiwan, Japan, and the U.S. comprises the most significant volumes with Taiwan leading with about one half of that volume overall. Much of the manufacturing involves the packaging of the LED die with a limited number of manufacturers creating the actual LED die material. Figure 1 illustrates the market size for low brightness and high brightness LEDs as a function of the total LED market.3 Low Brightness 36% High Brightness 64% ** Total LED Market: $5.74 Billion Figure 1 LED Market Segments LED Technology Breakthroughs Recent innovations in the manufacturing of the die material and packaging have resulted in ultra high brightness capabilities. The use of new materials for the substrate have allowed for improved thermal conductivity which allows for higher power consumption and net light output. This increase in light output has enabled new applications for LEDs such as automotive lighting, traffic signals, and more recently, television displays. An example of these new structures is illustrated in Figure 2. Al2O3 N Layer Quantum Wells Reflective Layer P Layer GaN Thermally Conductive Substrate Figure 2 Basic LED Structure Significant improvements in the production of Aluminum-Indium-Gallium-Phosphide (AlInGaP) and Indium- Gallium-Nitride structures have allowed for improved brightness in green and blue specifically. Additional colors such as amber and cyan are also 3 being developed at a rapid pace. These improvements enable system designs that can produce better color fidelity at near equivalent brightness to common lamp-based technologies with longer lifetimes. Additional performance enhancements include system level features like instant on, no mercury, no color refresh artifacts, dynamically adjustable brightness, and improved color gamuts. Figure 3 illustrates the gamut area for LED illumination as compared to the common reference standard (Rec. 709). LED Rec. 709 0 0 Figure 3 LED Color Gamut LED illumination provides a much larger color gamut (as much as 40% or more than the HDTV color standard [Rec. 709]), providing more accurate color fidelity. These performance attributes can be quite appealing for television applications where long life and excellent color fidelity are required. As LEDs continue to advance, their impact on television applications could be significant. Figure 4 illustrates the evolution of LEDs and their potential brightness efficiency in the coming years.4 200 Incandescent Lamps 180 W) 160 Flourescent Lamps / 140 (Lm High Pressure Arc 120 Lamps 100 Efficiency Light Emitting 80 Diodes 60 40 20 0 1940 1960 1980 2000 2020 Year Figure 4 Lighting Technology Evolution LED Technology Challenges Controlling the thermal stability of the LED die is critical to the performance and stability of LED illumination and reliability. The LED architecture inherently produces light from all sides and surfaces of the PN structure in a lambertian distribution (uniform distribution into a 180 degree hemisphere). While this might seem efficient, most of this light is actually absorbed into adjacent die, the mounting substrate, or other surfaces of the LED assembly. This absorption results in an increased thermal loading of the entire LED assembly. This heat must be addressed to obtain maximum light output and reliability. Additionally, for applications that require imaging of the light energy to a small display device (e.g. DLP ® HDTV), any light that is emitted outside of the system etendue is not useable and only adds to the heat and overall power loading. Controlling this absorption, shaping the light to match the system etendue, and maximizing the thermal efficiency to extract heat fr om the die are all critical to increasing the light output and usability of the LEDs. For traditional applications, LEDs are commonly driven in CW (continuous wave 100% duty cycle) mode. For high brightness applications, however, this is not as desirable. Since the average temperature of the PN junction 4 determines both the light output and lifetime of the LED, it is often more efficient to drive the LEDs with a smaller duty cycle. With a smaller duty cycle, the LEDs can potentially be driven to higher current loads to increase the overall light output while maintaining a lower average temperature of the PN junction. The challenge with this, however, is that the driver circuitry must be able to generate fast switching waveforms, switching large currents in as short a time as only a few microseconds. This certainly presents some challenges for the design of the LED power driver. But, solutions have already been developed with performance that easily meets these requirements. Another challenge that results from higher thermal loading is that of color shift. As the PN junction changes temperature, the output wavelength of the light can shift by as much as 10nm or more. This color shift obviously impacts the color point for that color, but also impacts the white point for the system since each of the colors are mixed to create white. Fundamentally, to stabilize this color shift, the LEDs must either be run at a lower power or maintain extreme thermal stability. However, with the implementation of some form of system feedback and proper power control algorithms, the stability of the white could be preserved while maintaining high brightness efficiency. DLP ® TV with LED Illumination TI has developed a DLP ® HDTV system to take advantage of LED illumination with brightness performance that is nearly equivalent to lamp based systems. By utilizing the latest generation of high brightness LEDs and implementing a unique feedback system, it is now possible for DLP ® HDTV designs to enjoy the benefits of LED illumination. Figure 5 illustrates the basic optical configuration of this system. Collimating Lenses Dichroic Filters Optical Integrator DMD TIR Prism Blue Array Green Array Red Array Condenser Lens Projection Lens  ® Figure 5 DLPP HDTV LED Optical Architecture Utilizing a unique feedback algorithm, TI has demonstrated that any color shift variations that affect the white point can be controlled to a tolerance beyond what the eye can detect. The current DLP ® products implementation with LED technology utilizes a TI DSP component to process system information in real time, offering superior stability over a wide range of operating temperatures while maximizing brightness and reliability. DLP ® Products Performance Advantages The rapid switching capabilities of LED technology match perfectly with the fast switching properties of DLP ® technology. By taking advantage of the high speed capabilities of the DMD and LEDs, it is now possible to utilize color refresh rates that are much higher than what exists with todays designs. It is also possible to randomize the color order. Ultimately, images can be created with higher bit depth, better motion fidelity, and higher brightness. By increasing the switching frequency of the LEDs, it is possible to drive them with increased power while minimizing the thermal loading of the PN junction. These fast switching capabilities of 5 DLP ® technology take advantage of the new LED colors that are becoming available, providing much more flexibility for multiple color configurations using a single DMD device. With a DLP ® system, the LEDs do not require polarization, reflecting the light precisely off of the DMD mirror surface. The light is used efficiently, only when it is needed. This maximizes brightness and system efficiency while reducing heat. The net result is a lower system cost with higher brightness and larger color gamuts that far exceed those possible by traditional systems utilizing other common illumination sources. Conclusion As LED technology developments continue to improve brightness and reliability, LED illumination may become more of a mainstream light source for many future applications. Future developments will be able to take further advantage of the fast LED switching time to improve video performance, enhance contrast without opto-mechanical components, and create adjustable color gamuts that far exceed the possibilities of traditional illumination sources. New products will soon benefit from these fundamental capabilities providing new, unique designs that offer instant on, better colors, and overall better picture using the speed of DLP ® micromirror arrays. With the advantages of LED and DLP ® technologies working together, it is expected that DLP ® HDTVs will provide even better performance with better reliability far exceeding any existing DLP ® HDTV product.

Optically Active Polymers

Optically Active Polymers Optically active polymers play very important role in our modern society. The speciality of optically active polymers are known with its various characteristics as occurred naturally in mimicry. The present review describes the monomers and synthesis of optically active polymers from its helicity, internal compounds nature, dendronization, copolymerization, side chromophoric groups, chiral, metal complex and stereo-specific behaviour. The various properties like nonlinear optical properties of azo-polymers, thermal analysis, chiroptical properties, vapochromic behaviour, absorption and emission properties, thermosensitivity, chiral separation, fabrication and photochromic property are explained with details. This review is expected to be of interesting and useful to the researchers and industry personnel who are actively engaged in research on optically active polymers for versatile applications. Optically active materials are those which can able to rotate the plane of polarization of a beam of transmitted plane-polarized light containing unequal amounts of corresponding enantiomers. The optical activity originates from the presence of chiral elements in a polymer such as chiral centres or chiral axes due to long-range conformational order in a macromolecule. In fact, most naturally occurring macromolecules possess the ability to organize to more complex high structure rather than single one and manifest their functions. Optically active polymers are related to problems of the charged and reactive polymers, since optical activity is an inherent property of both natural macromolecules as well as a great variety of polymers synthesized. Chiral compounds are optically active and essential for life such as proteins, polysaccharides, nucleic acids, etc. and chirality is most important for existence. About 97% drugs are formed from natural sources, 2% are recemates and only 1% is achiral, in looking of chirality of nearly 800 drugs. Optically active polymers today have also become of great interest and thus play an important role in molecular arrangement and assembly, which is critical for optoelectronics super molecular structure [1-4]. The synthetic optically active polymers may also play important role like mimicry of naturally occurring polymers and that’s why the extensive studies are required on their synthesis, conformations and properties. Various kinds of optically active polymers e.g., fro m its helicity, internal compounds nature, dendronization, copolymerization, side chromophoric groups, chiral, metal complex and stereo-specific behaviour are reported, however, those are not placed in a systematic manner. In the present review an effort has been made to collect most of those works in one place for better understanding in the subject with detailed explanation of properties like nonlinear optical properties of azo-polymers, thermal analysis, chiroptical properties, vapochromic behaviour, absorption and emission properties, thermosensitivity, chiral separation, fabrication and photochromism. -Classification of optically active polymers Optically active polymers are divided into three types: Biopolymers as obtained from nature. Polymers prepared by almost completely isotactic polymerization by modification of naturally occurring polymer backbones such as polysaccharides. Synthetic polymers as per the requirement with proper tailoring of functional groups. -Speciality of optically active polymer Optical properties of polymers are not so different of other substances, excepting those characteristics related to the chain dimension and structure or conformational changes. Optically active polymers have found interesting applications because of their specific properties. The optical properties of these materials lie at the basis of many applications, for example in chromatographic methods for enantiomeric separations or creating complex optical devices. The dispersion of the specific rotation offers information regarding the conformational changes or Cotton effect. Optically active polymers characteristics as follows: Optically active polymers with configurational chirality: the optical activity is given by the presence of an asymmetric carbon atom in the backbone or in the side chain of the monomer; Optically active polymers with conformational chirality: the optical activity is related to the conformational changes; Optically active polymers with both configurational and conformational chirality: the optical activity is given by macromolecular asymmetry and by the presence of the asymmetrical centers. -Monomers of optically active polymers Some biological polymers are composed of a variety of different but structurally related monomer residues; for example, polynucleotides such as DNA are composed of a variety of nucleotide subunits. The solid-state structures of polystyrene – poly(Z-L-lysine) block copolymers were examined with respect to the polymer architecture and the secondary structure of the polypeptide using circular dichroism, quantitative small and wide-angle X-ray scattering, and electron microscopy [5]. Synthesis of optically active polymers The optically active compounds are synthesized by highly efficient methodologies and catalysts. The various synthetic approaches for optically active polymers are described below: Helical polymer: Helicity is one of the subtlest aspects of polymer chain where the polymer chain spiral structure along the chain axis acts like a spring. Helical polymers are frequently occurring in nature in single, double or triple helices form in genes, proteins, DNA, collagen, enzymes, and polypeptides. The helical conformations increase the stability of the natural polypeptides. Preparation of artificial helical polymers is a great challenge to the researchers. So far, only limited success has been achieved in constructing microscale particles using helical polymers, despite the great number of analogous microparticles created from vinyl polymers and even from other conjugated polymers like poly(thiophene), poly(phenylene ethynylene), and poly(fluorene) and polyacetylenes. Meckings et al has performed extensive investigations on preparing nanoparticles from polyacetylenes, which have shown interesting potential in inkjet printing. Later on, various group of researchers have successfully prepared both nano and microparticles consisting of optically active helical substituted polyacetylenes [6]. Such nano- and microarchitectures demonstrated remarkable optical activity and significant potential applications ranging from asymmetric catalysis, chiral recognition/resolution, and enantiomer-selective crystallization to enantio-selective release [7-9]. Synthetic helical polymers may be classified as either static or dynamic helical polymers, depending on the inversion barrier of the helical conformation [10-11]. Static helical polymers have a relatively high energy barrier for helix inversion and are stable in solution, while dynamic helical polymers have a relatively low energy barrier for helix inversion and exist as a mixture of right- and left handed helical domains that are separated by rarely occurring helix reversals. Even a slight incorporation of optically active repeat units can shift the equilibrium to excess one-handed helicity. The chiral recognition properties of biopolymers with skilled emulating of synthetic helical polymers are currently a focus of much interest. Enantioseparation, catalysis, and sensing are among the more promising applications of molecular recognition based on responsive three-dimensional intramolecular or intermolecular superchiral structures. Optically active conjugated polymers represent an attractive class of chiral macromolecules adaptable to this purpose because their chiral behaviour can be augmented by nonlinear electrically conductive or optical properties arising from conjugation along the backbone. The first example of optically active polycarbazoles, poly[N-(R)- or (S)-3,7-dimethyloctyl-3,6-carbazole]s (R- or S-PDOC) were synthesized in 60-70% yield using modified nickel coupling method [12]. Helical polymers are easily denaturalized by certain physical factors e.g. heat, ultraviolet irradiation, and high pressure and by other chemical factors such as organic solvents. Various helical polymers have been synthesized, which include polyisocyanates, polyisocyanides, polychloral, polymethacrylates, polysilanes, polythiophenes, poly(p-phenylene)s, poly(1-methylpropargyl-ester)s, poly(phenylacetylene)s and poly(-unsaturated ketone) [13-19] (Fig. 1). Other polymers are whose optical activity is main chain or side chain chirality dependent e.g. amino-acid-based polymers are nontoxic, biocompatible and biodegradable. Optically Active Polymers Optically Active Polymers Introduction Optically active polymers are related to problems of the charged and reactive polymers, since optical activity is an inherent property of both natural macromolecules as well as a great variety of polymers synthesized. Most of the naturally occurring molecules/macromolecules, such as nucleic acids, proteins, and polysaccharides are chiral and optically active. Chirality is essential for life. This situation can be very obviously seen if  we look at the chirality of nearly 800 drugs (about 97%) derived from natural sources. Only 2% are racemates and only 1% is achiral. Synthetic optically active polymers are of great interests, since they might mimic the fascinating functions of naturally occurring polymers, leading extensive studies being conducted on their synthesis, conformations and functions. In fact, most naturally occurring macromolecules possess the ability to organize to more complex high structure rather than single one and manifest their functions. Optical activity is a ph ysical spectral property of chiral matter caused by asymmetric configuration, confirmations and structures which have no plane and no centre of symmetry and consequently have two mirror image enantiomeric forms of inverse optical rotation. The recemic mixture of chiral enantiomers is optically inactive. The great majority of natural molecules contain chiral centres and are optically active. This is the case because living systems and their extracts as enzymes are able to produce completely stereoselective asymmetrical synthesis or transformations. This led Pasteur to say that ‘life is asymmetrical’ at the molecular level. The majority of food and drug molecules of physiological activity are chiral [1]. Xi et al. [2-8] investigated about chirality of optically active compounds. Optically active polymers today have also become of great interest owing to their chiral structure which may play an important role in molecular arrangement and assembly, which is critical for optoelectronics super molecular structure [9-12]. Chiral polymers with helical chain backbone have received increasing attention due to their helicity generating from secondary interactions such as hydrogen bonds and van der Waals forces. These chiral helical polymers undergo conformational change as well as helical reversal easily. The concept of the optically active aromatic chromophore as ‘conformational probe’ in isotactic polymers can be further extended by the use of optically active monomers [13]. Optically active polymers have exhibited a number of interesting properties in several highly specialized areas such as chromatographic resolution of steroregular [14], chiral [15-16], asymmetric catalysis and phase of the separation of racemic mixtures [17], thermosensitivity [18], synthesis molecular receptors and chiral liquid crystals for ferroelectric and nonlinear optical applications [20]. In the last year [52], Angiolini and co-workers have synthesized and investigated methacrylic polymers bearing in the side chain the chiral cyclic (S)-3- hydroxypyrrolidine moiety interposed between the main chain and the trans azoaromatic chromophore, substituted or not in the 4’ position by an electron withdrawing group. In these materials, the presence of a rigid chiral moiety of oneprevailing absolute configuration favours the establishment of a chiral conformation of one prevailing helical handedness, at least within chain segments of the macromolecules, which can be observed by circular dichroism (CD). The simultaneous presence of the azoaromatic and chiral functionalities allows the polymers to display both the properties typical of dissymmetric systems (optical activity, exciton splitting of dichroic absorptions), as well as the features typical of photochromic materials (photorefractivity, photoresponsiveness, NLO properties). Recently, highly efficient methodologies and catalysts have been developed to synthesize various kinds of optically active compounds. Some of them can be applied to chiral polymer synthesis and in a few syntheses for optically active polymers; chiral monomer polymerization has essential advantages in applicability of monomer, apart from both asymmetric polymerization of achiral or prochiral monomers and enantioselective polymerization of a recemic monomer mixture. Optically active chiral polymers are not only fundamentally interesting, due to the rich and complex architecture of macromolecular chirality as compared to that of small molecules, but also technologically important because their unique chiral arrays give rise to a number of potential, and in some cases commercially implemented. Classification of Optically active polymers: Optically active polymers are divided into three types: Biopolymers: Biopolymers are the main type of biomaterials. According to their degradation properties, biopolymers can be further classified into biodegradable and non-biodegradable biopolymers. Many implants, such as bone substitution materials, some bone fixing materials, and dental materials, should possess long term stable performance in the body. Recently biopolymers acts as developments in bone tissue engineering, vascular tissue engineering, nerve tissue engineering, genitourinary tissue engineering, regenerative medicine, gene therapy, and controlled drug delivery have promoted the need of new properties of biomaterials with biodegradability. Biologically derived and synthetic biodegradable biopolymers have attracted considerable attention [21]. Polymers prepared by almost completely isotactic polymerization by modification of naturally occurring polymer backbones such as polysaccharides. Synthetic polymers: Polymers synthesized from low molecular weight compounds are called synthetic polymers, e.g., polyethylene, PVC, nylon and terylene [7]. This polymer is also divided into three types: (a) Addition polymers: Addition polymers are including vinyl, aldehyde, isocyanide and acetylene polymers that were prepared via addition polymerization reaction such as poly(acryl amide)s, polyolephynes, polystyrene derivatives, polyazulenes, poly(vinyl ether)s, polymethacrylate, polymethacryloylamine, polychloral, polyisocyanides, polyisocyanates, polyacethylene and polyethers [22–32]. (b) Condensation polymers: Condensation polymerization continues to receive intense academic and industrial attention for the preparation of polymeric materials used in a vast array of applications [28]. One of application is synthesis of chiral polymers. For this purpose, monomer must be optically active. (c) Cross-linked gels: One of application is synthesis of chiral polymers. For this purpose, monomer must be optically active. One of application is synthesis of chiral polymers. For this purpose, monomer must be optically active. Why optically active polymers are important? or Speciality of optically active polymer Optical properties of polymers are not so different of other substances, excepting those characteristics related to the chain dimension and structure or conformational changes. Optically active polymers have found interesting applications because of their specific properties. The optical properties of these materials lie at the basis of many applications, for example in chromatographic methods for enantiomeric separations or creating complex optical devices. The dispersion of the specific rotation offers information regarding the conformational changes or Cotton effect. Optically active polymers characteristics as follows: -Optically active polymers with configurational chirality: the optical activity is given by the presence of an asymmetric carbon atom in the backbone or in the side chain of the monomer; Optically active polymers with conformational chirality: the optical activity is related to the conformational changes; Optically active polymers with both configurational and conformational chirality: the optical activity is given by macromolecular asymmetry and by the presence of the asymmetrical centers. Monomers of Optically active polymers Polymerization is the process of combining many small molecules known as monomers into a covalently bonded chain or network. During the polymerization process, some chemical groups may be lost from each monomer. This is the case, for example, in the polymerization of PET polyester. The monomers are terephthalic acid (HOOC-C6H4-COOH) and ethylene glycol (HO-CH2-CH2-OH) but the repeating unit is -OC-C6H4-COO-CH2-CH2-O-, which corresponds to the combination of the two monomers with the loss of two water molecules. The distinct piece of each monomer that is incorporated into the polymer is known as a repeat unit or monomer residue. The identity of the monomer residues (repeat units) comprising a polymer is its first and most important attribute. Polymer nomenclature is generally based upon the type of monomer residues comprising the polymer. Polymers that contain only a single type of repeat unit are known as homopolymers, while polymers containing a mixture of repeat units are known as copolymers. Poly(styrene) is composed only of styrene monomer residues, and is therefore classified as a homopolymer. Ethylene-vinyl acetate, on the other hand, contains more than one variety of repeat units and is thus a copolymer. Some biological polymers are composed of a variety of different but structurally related monomer residues; for example, polynucleotides such as DNA are composed of a variety of nucleotide subunits. The solid-state structures of polystyrene – poly(Z-L-lysine) block copolymers were examined with respect to the polymer architecture and the secondary structure of the polypeptide using circular dic hroism, quantitative small- and wide-angle X-ray scattering, and electron microscopy [33]. Synthesis of optically active polymers Much of the attention in chiral polymers results from the potential of these materials for several specialized utilizations that are chiral matrices for asymmetric synthesis, chiral stationary phases for the separation of racemic mixtures, synthetic molecular receptors and chiral liquid crystals for ferroelectric and nonlinear optical applications. Presently optically active compounds are synthesized by highly efficient methodologies and catalysts. In a few synthetic approaches for optically active polymers, chiral monomer polymerization has essential advantages in applicability of monomer, apart from both asymmetric polymerization of achiral or prochiral monomers and enantioselective polymerization of a racemic monomer mixture [17].

1.  Ã‚  Ã‚  Ã‚  Ã‚  Review and approval of the previous meeting’s minutes. 2.  Ã‚  Ã‚  Ã‚  Ã‚  Financial overview from Rosaline, on Jim’s behalf. She shared the annual budget of Hope House (see page 7 of Hope House project proposal, Appendix A, attached). Rosaline then explained how money is obtained to meet expenses. There was a long list of either annual, monthly, or semi-regular donors. From month to month, however, there is no guarantee that money sufficient to cover expenses will come in. Rent is paid regularly, but other expenses are not. The people who usually suffer end up being the support staff, and the home is currently behind on their salaries. The home also has a large outstanding debt with Gertrude’s Garden Hospital. 3.  Ã‚  Ã‚  Ã‚  Ã‚  Rosaline then provided an overview of some of the Home’s key needs.

Basically there are 3 ways to make money: a solicitation campaign, selling a product, or hosting an event. There is no one-size-fits all perfect fundraising solution. Katherine emphasized the importance of having quality campaign materials (perhaps we could find a business willing to print these for us free of charge) and good publicity. The general wisdom is that no more than 2-3 initiatives should be undertaken each year so as not to exhaust either volunteers or donors. We also need to determine who our audience is: who would want to give to babies? Roz mentioned that here in Kenya it is generally best not to focus on using the money raised for wages, though Katherine K. said that this would not be a problem abroad. 5.  Ã‚  Ã‚  Ã‚  Ã‚  This led quite naturally to a productive brainstorming session on ways to fundraise.

Madness and Insanity in Shakespeares Hamlet - The Cause of Ophelias Insanity :: Shakespeare Hamlet Essays

Hamlet: The Cause of Ophelia's Insanity   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Shakespeare, through his intricate uses of symbolism and dramatic irony, arranges a brilliantly detailed account of how Hamlet's mental upheaval served as the driving force of Ophelia's   swelling insanity   and imminent suicide.   He floods the early acts with an impending sense of confusion within Ophelia, for her feelings toward hamlet greatly contrast those of her brother and father.   Ophelia begins to willingly take heed of her family's advice as the prince finds himself removed from a lucid pattern of thought. However, because her feelings for him are genuine, this serves only to exalt her mental strain.   In the height of Hamlet's incoherent rage, he provides Ophelia with the ultimate medium for her ensuing madness.   The murder of Polonius is the greatest among many factors that were contributed by Hamlet to the somber fate of Ophelia.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   A prelude, composed of warnings from Polonius and Laertes, is tactfully set up by Shakespeare during Ophelia's initial appearances in the play, aiding in the preparation for her subsequent mental deterioration.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Pol.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   What is between you?   Give me up the truth.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Oph.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   He hath, ny lord, of late made many tenders   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Of his affection to me.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Pol.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Affection, puh!   You speak like a green girl   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Unsifted in such perilous circumstance.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Do you believe his "tenders" as you call them?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Oph.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   I do not know, my lord, what I should think.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   (I, iii, ln.107-113)    Ophelia openly professes her confusion.   Polonius' response is presented in a manner which is clearly intended to sincerely disdain Hamlet before his daughter, making obvious his opinion of their involvement.   His intent for her actions, however, will merely magnify her confusion.   Ophelia concedes that she is not aware of a solution with which to halt or even improve this situation.   For this reason, no preventive measures are taken, only allowing the situation to worsen.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Hamlets mind grows more and more clouded as his goal becomes clear, and in the midst of his pervading preoccupation, he pushes Ophelia to the point of mental breakdown.   This notion appears in the second act, after Ophelia first sees a deranged Hamlet.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Oph.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Lord Hamlet†¦   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   †¦with a look so piteous in purport   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   As if he had been loosed out of hell   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   To speak of   horrors -he comes before me   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Pol.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Mad for thy love?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Oph.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   My lord I do not know   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   But I truly do fear it.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   (II, I, ln. 87-97)    Her confusion has evolved into a state of dread, and this dread will begin to penetrate her consciousness as it grows more and more intense.

In the year 710, the first permanent Japanese capital was established in Nara, a city modelled after the Chinese capital. Large Buddhist monasteries were built in the new capital. The monasteries quickly gained such strong political influence that, in order to protect the position of the emperor and central government, the capital was moved to Nagaoka in 784, and finally to Heian (Kyoto) in 794 where it should remain for over one thousand years. One characteristic of the Nara and Heian periods is a gradual decline of Chinese influence, which, nevertheless, remained strong. Many of the imported ideas were gradually "Japanized". In order to meet particular Japanese needs, several governmental offices were established in addition to the government system, which was copied after the Chinese model, for example. In the arts too, native Japanese movements became increasingly popular. The development of the Kana syllables made the creation of actual Japanese literature possible. Several new Buddhist sects that were imported from China during the Heian period, were also "Japanized". Among the worst failures of the Taika reforms were the land and taxation reforms: High taxes resulted in the impoverishment of many farmers who then had to sell their properties and became tenants of larger landowners. Furthermore, many aristocrats and the Buddhist monasteries succeeded in achieving tax immunity. As a result, the state income decreased, and over the centuries, the political power steadily shifted from the central government to the large independent landowners. The Fujiwara family controlled the political scene of the Heian period over several centuries through strategic intermarriages with the imperial family and by occupying all the important political offices in Kyoto and the major provinces. The power of the clan reached its peak with Fujiwara Michinaga in the year 1016. After Michinaga, however, the ability of the Fujiwara leaders began to decline, and public order could not be maintained. Many landowners hired samurai for the protection of their properties. That is how the military class became more and more influential, especially in Eastern Japan. The Fujiwara supremacy came to an end in 1068 when the new emperor Go-Sanjo was determined to rule the country by himself, and the Fujiwara failed to control him. In the year 1086 Go-Sanjo abdicated but continued to rule from behind the political stage. This new form of government was called Insei government. Insei emperors exerted political power from 1086 until 1156 when Taira Kiyomori became the new leader of Japan.

Monkey in the mirror

Monkey in the mirror is a book written by Ian Tattersall and it was published by the oxford university press in the year 2002 with 203 pages and the serial number is ISBN 0-19-851569-3. Tattersall a curator by profession is a PhD holder From Yale University,Tattersall, a Briton, is a curator in the Division of Anthropology of the American Museum of Natural History â€Å"Dr. Tattersall is currently working with Research Associate Jeffrey Schwartz on a multi-volume project to document the major fossils in the human fossil record. The literature as it stands is not a good resource for comparing human fossils, because standards of description and terminology vary widely. Because it employs a consistent descriptive and photographic protocol, this new work will make it possible for the first time for colleagues, students, and others to make the necessary comparisons without the extensive travel needed to consult the originals, which are in institutions all over the world. It will thus be a unique resource for pale anthropology that will spur future research† by D.S.G. POLLOCK â€Å"According to tattersall this is a great book having researched on it well and pointing to a lot of essays and as we all know human history or geology is a difficult topic and needs much research before one tries to defend his/her argument and as tattersall explain in his preface, â€Å"this is a somewhat unusual book, being â€Å"a series of loosely connected essays on evolution and related subjects† rather than a tightly constructed argument. Presumably because of this, it lacks both an index and any references or even a suggested reading list, which is a rather unfortunate limitation, especially in view of its author's somewhat contentious views† Campbell. Copyright  © Anthony Campbell (2002) The book in all has eight in which tattersall has discussed different issues brings out Where the man came from that is according to evolution theory which he has stated different parts of the world. The first two paragraphs are of general information about what science and evolution is. He firstly discuss what science is and theory and its findings and what it helps us in modern day to understand The first chapter of the book, titled What's So Special about Science?, provides a surprising insight into the cultural context in which Tattersall works. at the American museum In these, Tattersall sets the scene for what follows. He is particularly keen to counter the idea that adaptation in evolution is â€Å"for† anything. Novelty arises on a haphazard basis and it is purely a matter of luck if it turns out to have a beneficial effect on survival and reproduction. About novelty in evolution, tattersall supports the view that radial innovations can appear in select few the rest of the book is concerned in one way or another â€Å"with aspects of human evolution. In a chapter called â€Å"The Monkey in the Mirror†, which is also the title of the whole connection, Tattersall considers the question of which animals are capable of recognizing their own reflection (only humans and some though not all apes), and considers the connection, or lack of connection, between brain size and intelligence. Although we often think that a large brain is what mainly distinguishes us from other species, pre-human hominids were not chiefly remarkable for the size of their brains. Instead, Tattersall identifies three features that he thinks are important in this regard: upright stance, the use of stone tools, and a â€Å"modern† body form.† Anthony Campbell. â€Å"Tattersall devotes a full chapter to Homo erectus and the Australopithecenes who preceded him; and he is emphatic that the transition from one to the other was abrupt. Another of the evolutionary themes that Tattersall is keen to emphasize is denoted by the inelegant neologism of exaptation† pollok Neanderthals has a complete topic dedicated by tattersall and adopts the view that they were not ancestral to us but are of different species he holds a view that they were killed by our own ancestors and has a believe that the they could have interbred. Chapter Seven consist of a sustained attack on evolutionary psychology and sociobiology. Tattersall is scornful of the idea that our present-day behavior is conditioned by our long evolutionary background as hunter-gatherers or that our psychology is dependent on our genes. â€Å"However, I think there is a better case to be made out for such ideas than he allows, and his inevitably rather brief discussion of it is one-sided† Kevin N. Laland and Gillian R. Brown. â€Å"Tattersall's account of man's evolution conveys a modern message. As far as the science of paleoanthropology is concerned, it is up to the minute in the way that it reports the tenor of current thinking. It has been written with such facility and in such affluent prose that, sometimes, its cutting edge is too well concealed. It can take an effort of concentration, far beyond what the book ostensibly requires of the reader, to anatomize its rich and complex message. But, any reader who is prepared to devote time and thought to this brief book will be abundantly rewarded† Stephen Pollock. The final chapter forecast the future. in his essay he says, I quote: â€Å"It is fairly pessimistic about our chances of survival. As a consolation prize, however, if humanity is reduced to scattered pockets of survivors in relative isolation from one another there will be a chance for evolution to take off again; a large and unified population like ours today does not afford the fragmentation and isolation that is needed for selection to act.† tattersall Conclusion To conclude and in short, tattersal is a profound writer and this book is exceptional and will interest anyone who envies evolution of the current day. And as we see the book has no references and this is a set back because readers will not have an alternative incase they want an alternative view.
