Fiedler and Garcias Cognitive Resource Theory Essay

Fiedler and Garcia - Essay Example The theory predicts that uncertainty and stress are the two factors, which worry a leader. Fiedler connects this to his Least Preferred Co-worker Theory (LPC theory) where a high LPC leader will be more likely to give high scores to the people he has worked with earlier while a low LPC leader will be more inclined to assign low scores for the same. When the control of a leader over a situation and his LPC score are in tune with each other, good performance of leadership will result. Again, when a low LPC score leader is in a situation of moderate control and high LPC leaders are in situations of high control or low control, the LPC and situational control are not in line with each other. The transition from his â€Å"in match† condition to the not â€Å"in match† condition will bring about stress and worries in the leader owing to a â€Å"perceived inability to deal with situations of this nature† (Miner, 2005, p.250). When a particular circumstance causes anxiety in the leader he tries to gain confidence from his â€Å"previous successful reinforced behavioral patterns†. On one hand, the effective level finds this behavior has dealt with earlier cases of dealing with interpersonal issues while on the other hand, the cognitive level finds that such behaviors show what one learned from experience. The efficacy of the behavior of the leader is conditioned by the matching of the situations’ demands and the leader’s response to the same. Thus the model works under two assumptions. First, managers let their subordinates know their plans via directive behavior and second, leaders with greater experience and smartness have better decision-making ability than the ones who are less intelligent or experienced. Hence, one may say that when a leader is under stressful conditions, intelligence does not function efficiently or with full effect and even might have a negative impact. A leader should search for previous experience under similar situations from where he might derive some strength and decision making power. Again under a high-stress scenario, the intelligence is often damaged, but experience might help the leader respond well to the situation. Again when the task is simple then the leaders’ effectiveness does not matter because even the subordinate will be able to handle it. (Cognitive Resource Theory n.d.) Therefore when the situation is stressful a leader with greater experience will be more reliable to handle it. When a leader has the lesser level of experience he should undertake relatively stress-free assignments and the level of stress should be gradually increased with experience.            

Gdp And Economic Welfare Essay Example for Free

Gdp And Economic Welfare Essay Gross Domestic Product (GDP) is the most important economic indicator and it is used for comparison purposes to see how countries are doing economic wise. It entails the aggregate production or output in a country. GDP can be measured using either the expenditure approach where all final expenditures are added or by the income approach where all compensations of employees and other forms of incomes are added up. GDP is used to measure an economy’s economic growth. Hartzenberg T et al (2005, 114). The real GDP can be used to establish how an economy is performing and hence compare various economies as one can compare their outputs. It is also important in the sense that it can be used for forecasting purposes and hence important in planning. This paper will distinguish the difference between economic growth which can be measured using GDP statistics and national welfare or people’s well being. According to McConnel and Brue in their distinguished book ‘Economics’, a country can be said to have economic growth when there is a positive increase in its GDP. Economic growth is different from economic welfare and economic development. Economic growth is characterized by an increment in natural resources, the quantity or quality for the human resources, as well as an improvement in technology that translates to increased productivity. Economic growth refers to a positive shift in the production possibility curve to the right or where economic efficiency is attained. McConnel and Brue (2005, 149). A country A could register a higher GDP than country B but this does not necessarily mean that country A is doing better in terms of economic welfare as there is a clear distinction between economic growth and national welfare. This can be blamed on the limitations attached or rather linked to GDP calculation and analysis. (facstaff. uww. edu). Walter in the book ‘Economics’, noted that GDP ignores or rather omits household production which is an important sector in as far as determining the welfare of people is concerned. Wessels W (2006, 75). Alan and Laurence backed this idea in their book ‘Macroeconomics an integrated approach’ where they argued that GDP does not account for the unreported incomes which are earned in the ‘underground economy’. A good illustration of unreported incomes is a situation where waiters fail to report all the tips they acquire while on duty. People may fail to report their actual incomes to evade taxes. Statistical problems could also have occurred creating the impression that country A had a higher GDP than country B though this may not be actually be the case. Some people may not divulge all the information regarding their incomes or expenditure leading to wrong GDP estimates. If country B has a very significant ‘underground economy’ then her citizens could be doing better than those in country A even though the latter had a lower GDP. This is an indication that high GDP rates do not necessarily translate to better welfare for the citizens. Auerbach and Kotlikoff (1998, 136). When calculating GDP the aspect of leisure is ignored although it is very critical in as far as defining people’s welfare is concerned. Country A could register a higher GDP than country B but the citizens in country A could have been overworked leading to health complications. In this case, the high GDP could be at the expense of the people’s health and we cannot conclude that it ensured their welfare or well being. Wessels W (2006, 75). Using GDP figures to determine the people’s welfare is inappropriate as it fails to include ecological costs incurred in the process of attaining the said GDP. Ecological costs include the costs of pollution. Country A could register a higher GDP than country B due to the fact that country A had better technology that ensured increased production. However, the increased production could have been realized in the face of increased air, water and land pollution all of which poses health hazards to the citizens. Wessels W (2006, 75). When such is the case then we cannot conclude that country B is doing better than country A. People’s well being encompasses the people’s health and not just their economic well being. A country with lower GDP but ensuring that her environment is safe for her citizens is doing well in terms of national welfare even though it could record a lower GDP than one with a higher GDP but has a polluted environment. GDP ignores a country’s environmental quality and it fails to account for the consequences that an economic growth could come along with. Auerbach and Kotlikoff (1998, 136). GDP also focuses on output or production although it is consumption that could best explain people’s welfare. For instance country A could sell more goods to other nations like country B since the demand for such goods in country B is higher. In this context, country B could be doing better than country A but since country A exports more it may create the impression that it is doing better. On the other hand, country B may register a lower GDP translating to being worse off as her net exports are negative but in the real sense they could be doing better. Focusing only on the output approach would lead to distortions while addressing the issue of national welfare. Another critical issue cited by Wessels as a limitation of using GDP to evaluate a country’s or nation’s well being is the fact that government spending is valued at cost rather than at its value. Government projects in country A could have been at a higher cost than those in country B but an important aspect to consider here is how much the projects were worth to the citizens. This is because some important projects could be undervalued while worthless projects are overvalued and this will have a significant impact in as far as influencing the people’s welfare or well being is concerned. Wessels (2006, 75). GDP calculation does not include the plight of the people in terms of health and life expectancy which are quite important in assessing the people’s well being or welfare. Country A could have a higher GDP than country B but if she has a lower life expectancy rate and is performing poorly in terms of general health of her citizens then we cannot argue that her citizens are better off than those of country B especially if in country B the life expectancy and general health is better. Health which is a very important factor in determining the people’s welfare when calculating a country’s GDP people’s conditions health wise are only included if they increase the costs of the health system. A country’s health costs could be attributed to modern and advanced health technologies but this does not guarantee a nations well being health wise as the costs incurred may not match the benefits attained. Democracy or political freedom is an important part in determining people’s welfare. Good governance is one where respective freedoms are respected and most importantly democracy embraced. Using GDP to evaluate people’s welfare is inappropriate as it does not provide any information regarding a country’s governance. Country A could register a higher GDP than country B but the political organization in country A could be oppressive to the citizens. In this context, we cannot argue that country A citizens are better than those in country B which could be exercising democracy and consequently not oppressing her citizens. (facstaff. uww. edu). Another vital issue in defining people’s well being is assessing social justice in a country. If country A registered a higher GDP but was very poor in terms of the civil justice system then we cannot conclude that her citizens well being was ensured. Country B citizens could be doing better at a lower GDP level if she ensured an effective social justice system. An effective system ensures that the rule of law is embraced and people’s rights respected. This is important in ensuring that corruption which threatens people’s welfare as it only benefits a segment of the total population is kept at bay. Using GDP to compare the well being of people in country A and B could give a wrong impression of what is actually the case. This is attributed to the fact that a country could have overly adjusted for inflation leading to the impression that increase in prices translate to hikes in prices even when this could be as a result of improvement in the products produced. Morse S (2004, 39). Another aspect that makes it inappropriate to compare country’s welfare using the GDP statistics is the fact that for such comparisons one must convert the currencies into the other country’s currency and when carrying out the conversions it is possible to understate a country’s GDP especially in the developing nations. A country A could register a higher GDP than country B due to errors arising from conversions of currencies. (facstaff. uww. edu). Country A could have a higher GDP than country B but her citizens could be worse off than those of country B in terms of national welfare. This is attributed to the fact that country A could be characterized by many social evils as opposed to country B. Failure to include the non-market production in the calculation of GDP makes it an inappropriate tool in determining people’s welfare in an economy. Such services like childcare, subsistence farming and care for the aged mean a lot in as far as people’s welfare is concerned. Country A could have a higher GDP but with a lower subsistence economy when compared to country B. A significant subsistence economy would ensure that a country’s food security is ensured and this would place her citizens at a better stance in as far as their well being or welfare is concerned. GDP fails to account for the effects or consequences of technology which has an impact in its determination. In contrast GDP is more concerned on the value of the end product without taking to concern the efficiency of the technologies in question. If country A registered a higher GDP than country B but country A’s government invested more in sectors like education and health ensuring that her citizens were better off in those areas then we can conclude that country B’s welfare is doing well even if it has a lower GDP than country A. Treating investment in education and health as consumption rather than investments makes it difficult to estimate people’s welfare. Willis I (1997, 164). Distribution of resources in a country is also a point to consider when using GDP figures to estimate people’s welfare. Country A could register a higher GDP than country B but this high GDP could have been arrived from a small insignificant proportion of the total population. This is to say that it is inappropriate to say that country A citizens are doing better than those in country B as the GDP is contributed by a small proportion while a large proportion of the society could be languishing in poverty. Income distribution is of much essence when determining people’s welfare in an economy. The inequality issue and GDP arise more so in developing countries or third world as opposed to developed ones. Willis I (1997, 164). Social issues like family stability are also not reflected when calculating GDP although it has an impact on people’s welfare or well being. GDP in country A could be higher than that in country B as more money is being channelled into paying divorce cases lawyers or building more police posts in response to increased crime rates. This illustrates that it is inappropriate to make conclusions about people’s welfare using GDP. In his book ‘The Japanese Economy’, Mitsuo Saito noted the inappropriateness of GDP as a tool of evaluating people’s well being due to the fact that it does not indicate the labour conditions, housing conditions, state of the social security or the urban life which are crucial in determining people’s well being. Saito M (2000, 13). Economic growth could be based on either the demand side or the supply side of an economy. The aggregate demand could increase due to an increment in the population size while aggregate supply could be due to the discovery of new natural resources. Aggregate output is affected by the level of labour supply, the stock of accumulated capital, level of technology as well as the institutions in place. There is an inverse relationship between prices levels and output and when prices levels fall the output increases. Tanzi and Chu (1998, 203). Monetary and fiscal policies in a given economy would affect the country’s well being or welfare. The people’s welfare will be affected by the policies that an economy embraces. Good policies are those that aim for equitable economic growth in a nation. They ensure that the poor in the society are not worse off but instead uplift them. This can be achieved through the application of equitable taxes such that people’s ability to pay is what determines the amount they are to pay all taxes. The rich will pay a higher amount than the poor in such cases. The government could also apply fiscal policies to ensure development for the poor in society. References: Alan J. Auerbach, Laurence J.

Hormones and Dreaming

â€Å"I Dreamed A Dream† We all dream, it is inevitable. You dream about people, places, homework, daily doings, and even things you don’t even recognize as being a part of our life. People may often question the significance of dreaming or why humans do it, but it is an essential part for our brain function as you sleep and live day to day. It allows for our minds to process the input it receives. There have been ample researchers who have studied the brain and its relationship with dreaming.Most people are aware of the influence hormones have on the behavior of a person. However, such hormones have also been linked to the dream process and their content. My goal through this research paper is to identify several hormones, naturally secreted by the body, and the impact they have on the dreaming process for both males and females, with a particular focus on females. The articles provide evidence as to what specific hormones from the body affect dreaming and how the horm ones enable that to occur. Article 1: Sleep, dreams, and memory consolidationIn this article, Payne and Nadel did not perform any actual experiments themselves; they did review the results of a number of different studies pertaining to cortisol and dreams. Researchers focused on the effects of brain neurohormones, specifically cortisol, as it impacts sleep, dreams, and memory. Researchers believed that variations in amounts of cortisol, as well as other neurotransmitters, affect the hippocampal formation and neocortical circuits, two parts essential for fusing memories, a process which occurs during sleep usually through dreams.It is important to understand that cortisol is released by the adrenal cortex in response to stress and low levels of blood glucocorticoid meaning. Researchers of the studies that were reviewed provided background and assumptions for topics concerning sleeping and dreaming such as the sleep stages, the distribution of dreams, and the relationship between drea ms, sleep, and memory consolidation. First, sleep does not merely serve one purpose for humans.Second, content of dreams shows which portions of the brain are active. Third, if cortisol levels affect the hippocampal formation then the stages during sleep in which memory consolidation occurs will be also altered. In the studies looked at by Payne and Nadel, all findings showed that cortisol levels do fluctuate during a night’s sleep based on the sleep stage (REM, NREM, SWS). Some studies also indicated that sleep strengthens communication for the neocortical circuits and hippocampal formation.Many of the same studies continued to point out that the changes in cortisol levels interrupt the hippocampal formation function, which is the processing of episodes, and neocortical interactions. The results therefore alter dream content because the two brain parts are closely linked with dreaming during sleep. This dream interruption comes because the brain is attempting to integrate th e information with pre-existing knowledge and other related concepts.The findings compiled by Payne and Nadel are examples of biological psychology, which displays the relationship between human behavior, the mind, and biological processes in comparison with the influence of neuroscience and chemical/hormonal reactions, specifically cortisol. Cortisol is known to increase with age because of its role as a stress response hormone. Stress increases as age increases, therefore the connection between cortisol and dream interruption is also a part of developmental psychology because it is a change that occurs throughout a lifespan.These findings are also relatable to a cognitive psychological perspective since the studies investigate the mental process of dreams and how the brain sorts through new information and past information; simply stated: it is cognitive psychology because it is the brain working as one sleeps. These articles go into depth about the process of dreaming and how it is affect negatively by cortisol. Payne and Nadel also demonstrate social psychology, which is how our behavior is affected by others, in their review.Cortisol can be released by the body as a response to the stress brought about by others meaning that the behavior produced in our dreams is a result of our interactions with those around us. It would not be necessary to cut off contact with the world to decrease stress levels and attempt to control amounts of cortisol secreted by the body, but it can help people understand their own dream process through the night. Article 2: The Influence of the Hormonal Cycle on Dream Recall in Women In the dissertation by Phyllis Bales, Bales focuses on the impact of womens’ hormonal cycle in relationship to dream intensity, vividness, and content.As demonstrated in the first article, hormones can have a pronounced effect on dreams while sleeping because of hormonal influence on the brain. She hypothesized three things: first, there would b e higher dream activity and recall during the luteal phase, when large amounts of progesterone are emitted; second, dream intensity would be higher during the luteal phase; third, thematic content would co-vary with the hormonal, or menstrual, cycle. Bales performed a study with seven female subjects who were not taking birth control, since birth control is known to alter hormone balances.These participants kept a Dream Analysis Questionnaire and Menstrual Distress Questionnaire throughout the study, to track the content, intensity, and vividness of their own dreams. The findings from her study supported some of her initial hypotheses. The questionnaires showed that there was no difference in dream activity during the pre- and post-ovulatory phases, however, there was a significant increase in dream recall following the post-ovulatory phase, also known as the luteal phase as mentioned previously.Another influence seen in the luteal phase was an increase in maternal dreams along with their duration and intensity concerning maternity. These results proved to be consistent as shown through other studies that even used different methodologies. Bales’ study and dissertation are relatable to individual difference/personality with psychology as the results may vary insignificantly from person to person by extremely small numbers because of interactions with the environment, but will constantly be similar among women as a group, as long as they experience a menstrual cycle and have not entered menopause.An interesting perspective to consider is evolutionary psychology because of its inclusion of behavioral differences among individuals in response to changing physical and social environments. Women may experience such differences in dreams as part of variations between males and females. Through history, females have been the ones to bear children, never men, as told in the bible, but there is the chance that the body may have undergone experiences that have al tered the body in turn altering the mind, including dreams.Article 3: Menstrual hormone changes and instinctual tendencies in dreams In this paper by Judith Baron, Baron investigates whether the female sex hormone, progesterone, contributes to the content of dreams. Her main hypothesis was: the themes of dreams are more likely to contain maternal content when progesterone levels are high in the post-ovulatory or luteal phase. As part of the study included in the paper, seventeen female college students completed dream questionnaires for every dream remembered over two menstrual cycles.Then, scales were created to measure obvious and symbolic dream content. Menstrual cycles were divided into follicular, without progesterone, and luteal, with progesterone, phases for comparison within each subject of dream content. Conclusions taken from this study showed that there were higher obvious and symbolic maternal scores in the luteal phase. It was concluded that hormones do influence matern al instinctual tendencies as expressed in dreams and supported Baron’s beginning hypothesis concerning dream content in relation to progesterone levels.Again, this study backed the hypothesis that hormones do affect dream content. These findings suggest two things: first, hormones do impact the content of dreams; second, specifically progesterone has been linked to increase the maternal content in females’ dreams. This study is relatable to cognitive psychology because it is strongly tied with internal mental processes as the hormones influence the dreams females have and remember, even what they may learn from these dreams.Baron’s results are also representative of a biological perspective since it focuses on the biological foundations in relation with behavior and mental processes, including dreams. Progesterone released by the body affects the behavior that occurs in dreams for women. Conclusion People dream each night because it is our brain’s way of processing new experiences and information for our brain. Dreaming can be fun as it pertains to enjoyable events, like reliving a date or time with a loved one, or it can be terrifying as through nightmares, where our worst fears seem real.I have experienced both ends of the dream content spectrum as I have dreamt about a cute guy or even about death. Looking back at the findings in these articles, I am better able to understand the context in which these dreams happened and rationalize the occurrence I experienced. As a female, this research brings to light the even greater differences that are seen by scientist between men and women. We already have different physical features and behaviors which are linked to the dreams we experience.These physical features and behaviors are typically tied with hormones like testosterone, progesterone, and cortisol, the same hormones that affect dream processing, content, and vividness. With ovulation, the findings of increased maternal dreams in a sleeping pattern can also help women understand the reasoning behind why they are experiencing more dreams about being a mother. Some people may question the importance of such information concerning hormones and their effects on dreams, but it is important to note that many of our bodies’ hormones are released without real control over them.They are a response to outside stimuli or other impacts from our environment. With this research, we are able to answer two rather popular questions as to what our dreams may mean or why we had the dreams we did. Take the time to evaluate the environment around you, whether it is ovulation, stress, or even pregnancy. One thing to consider the next time you dream are the hormones your body may be producing and how they may be affecting your dreams. So next time you recall a dream, just ask â€Å"is a dream really a wish your heart makes? †

Free Essays on Macbeth Hamlet Comprison

William Shakespeare, the playwright of both Hamlet and MacBeth, conveys a theme of deceit, revenge and death throughout both plays. Deceit plays a major role in the activities that result in the death of numerous innocent victims as well as the two main characters that are victimized themselves by a series of murders and plots against them that are a direct result of revenge. The guilt and remorse Hamlet and MacBeth fell as a result of these events eventually leads to their own destruction. In the beginning of the play Hamlet, the main character’s father has been killed. His father’s ghost appears to him and tells him that is was his uncle, Claudius, who poisoned him. At this point, he cannot trust any one, not even his own family. It goes even further with the fact that Claudius will be marring his mother, Gertrude. â€Å"He cannot be sure whether he can even trust his own mother in the struggle for power that takes place later in the play† (Watt 160). Killing for revenge is a theme exhibited throughout this play. â€Å"As events continue, the reader comes to realize that by the end of the play the characters of Hamlet, Fortinbras and Laertes have all had their fathers killed, the main reason being revenge† (Campbell 109). The fact that Fortinbras father (the King of Norway) was in fact killed by Hamlet’s father before the play even began sets the tone of revenge. The theme of unending revenge killing is introduced by relaying events that took place before the play.

Free Essays on Macbeth Hamlet Comprison Free Essays on Macbeth Hamlet Comprison William Shakespeare, the playwright of both Hamlet and MacBeth, conveys a theme of deceit, revenge and death throughout both plays. Deceit plays a major role in the activities that result in the death of numerous innocent victims as well as the two main characters that are victimized themselves by a series of murders and plots against them that are a direct result of revenge. The guilt and remorse Hamlet and MacBeth fell as a result of these events eventually leads to their own destruction. In the beginning of the play Hamlet, the main character’s father has been killed. His father’s ghost appears to him and tells him that is was his uncle, Claudius, who poisoned him. At this point, he cannot trust any one, not even his own family. It goes even further with the fact that Claudius will be marring his mother, Gertrude. â€Å"He cannot be sure whether he can even trust his own mother in the struggle for power that takes place later in the play† (Watt 160). Killing for revenge is a theme exhibited throughout this play. â€Å"As events continue, the reader comes to realize that by the end of the play the characters of Hamlet, Fortinbras and Laertes have all had their fathers killed, the main reason being revenge† (Campbell 109). The fact that Fortinbras father (the King of Norway) was in fact killed by Hamlet’s father before the play even began sets the tone of revenge. The theme of unending revenge killing is introduced by relaying events that took place before the play. Hamlet and Ophelia’s relationship gives other examples of deceit and revenge that eventually result in death. At first, Hamlet cannot trust anyone, so he goes to Ophelia to confide in her.

A Brief History of Slot Machines

A Brief History of Slot Machines According to Legal Slots, the term slot machines was originally used for all automatic vending machines as well as for the gambling devices, it was not until the 20th century that the term became restricted to the latter. A fruit machine is one British term for a slot machine. The one-armed bandit is another popular nickname. Charles Fey Liberty Bell The first mechanical slot machine was the Liberty Bell, invented in 1895 by car mechanic, Charles Fey (1862–1944) of San Francisco. The Liberty Bell slot machine had three spinning reels. Diamond, spade, and heart symbols were painted around each reel, plus the image of a cracked Liberty Bell. A spin resulting in three Liberty Bells in a row gave the biggest payoff, a grand total of fifty cents or ten nickels. The original Liberty Bell slot machine can still be seen be at the Liberty Belle Saloon Restaurant in Reno, Nevada. Other Charles Fey machines include the Draw Power, and Three Spindle and the Klondike. In 1901, Charles Fey invented the first draw poker machine. Charles Fey was also the inventor of the trade check separator, which was used in the Liberty Bell. The hole in the middle of the trade check allowed a detecting pin to distinguish fake nickels or slugs from real nickels. Fey rented his machines to saloons and bars based on a 50/50 split of the profits.​ Demand for Slot Machines Grows The demand for Liberty Bell slot machines was huge. Fey could not build them fast enough in his small shop. Gambling supply manufacturers tried to buy the manufacturing and distribution rights to the Liberty Bell, however, Charles Fey refused to sell. As a result in 1907, Herbert Mills, a Chicago manufacturer of arcade machines, began production of a slot machine, a knock-off of Feys Liberty Bell, called the Operator Bell. Mills was the first person to place fruit symbols: i.e. lemons, plums, and cherries on machines. How The Original Slots Worked Inside each cast iron slot machine there were three metal hoops called reels. Each reel had ten symbols painted on it. A lever was pulled that spun the reels. When the reels stopped, a jackpot was awarded if three of a kind of symbol lined up. The payoff in coinage was then dispensed from the machine. Age of Electronics The first popular electric gambling machine was the 1934 animated horse race machine called PACES RACES. In 1964, the first all-electronic gambling machine was built by Nevada Electronic called the 21 machine. Other all electronic versions of gambling games followed including ones for dice, roulette, horse racing, and poker (Dale Electronics Poker-Matic was very popular). In 1975, the first electronic slot machine was built by the Fortune Coin Company.

Dealing with academic challenge Essay Example | Topics and Well Written Essays - 750 words

Dealing with academic challenge - Essay Example The students feel that their peer of the dominant culture has greater experience in all or most things. Consequently, the fresh students may be reluctant to communicate their contrary opinions and may be influenced in accepting offered opinions by the other students, supervisors, or tutors. Self-concept into autonomy (Carr, 2013) is however a solution to this problem and requires input from different stakeholders such as the freshman international students, their classmates, their teachers, and their parents and family. Even though discussing the concept from a more specific perspective, Conradi (2014) explains the role of self-concept in motivation. The belief in oneself is likely to help a student confront divergent views for a better understanding of course concepts. Even when in doubt, a foreign and freshman student is able to overcome cultural limitations such as language barrier and to express opinions on learnt concepts for correcting wrong opinions from others and for facilit ating correction of personal opinions that may be wrong. Consequently foreign and freshman students should receive necessary support for developing positive self-concept towards active participation in class discussion and assertiveness in arguments for learning purposes. Teachers play an important role in creating a favorable environment for self-concept through mediation. Motivation from parents and support from peer are other factors to the role of self-concept in facilitating confidence in expressions and autonomy in learning. Interpersonal relationships with fellow students from either the dominant culture or those with experience in the culture as well as relationships with academic professionals are another solution to challenges that freshman international students face. Such associations are likely to expose a new student to academic challenges and possible solutions and therefore aid

Personal Response on Sexuality Identity Term Paper

Personal Response on Sexuality Identity - Term Paper Example So, it is very clear that the people from these different geographical areas will have totally different notions about sex. I too, being a product of the western society had a broad outlook about sex from the very beginning, though this course has, I think, made me think more critically in sexual decisions. Social factors that have a bearing on my sexuality According to the western, especially American concept of sexuality that prevails among the youth, sex is more of a recreational activity that does not have any connection with morality. It is a male dominated society where the ability to lure as many women as possible is considered a way to prove ones maleness. For females, the credibility lies in the ability to hook a man to ones armpits. The role of media cannot be denied in this social situation. According to reports, 8 out of 10 prime-time shows in America have sexual content; thus making sex a very common thing among the youth, having no emotional or ethical value (Dykeman, D uncan, Irvin, King, n. d.). The liberal view of the society I live in about sex is evident from the result of a survey. As per the survey, nearly 90% Americans believe that boys and girls will not wait until marriage to have sex; and only about 17% people were against oral sex and even they had serious doubts about the achievability of their expectations (NPR/Kaiser/Kennedy School Poll, n.d.). Thus, I found sex as a privilege to be enjoyed since adolescence, though I had little discussion with my parents about sex. Despite the liberal attitude towards sex, I would admit, it seems difficult to have open discussions with parents. In fact, my ideas about sex are all collected from friends and the media. I think it is the social freedom we people enjoy that makes sex very possible everywhere. I know there are countries where people seldom go to clubs, or are strictly under the supervision of the parents. However, being the product of an industrialized society, my parents never put a lot of pressure on me to reveal where I am going and who I am meeting. I think it is common for the youth in my country to have this freedom and as a result I had a well defined sexuality since the very beginning of my adolescence which was highly liberal in nature. Even when I got married, I would admit, I did not think that marriage was in no way going to affect my sexual relations. My perceptions on sex and the role of critical thinking Frankly speaking, I never thought of the role of ethics in sex. Though at times I read here and there about the issues associated with plurality in sex and the advantages of having a single sex partner, it seemed a rather impossible proposition in the society I live in, especially because of the lack of emotional attachment the sexual partners posses to each other. In the society I live in, there has been a gradual deviation from the traditional concept of sex as associated with marriage. Being in a society where sex is in no way connected to wedlock and childbirth, and hence not binding, I, like any other young person in the country, prefer to view sex as a physical need; the result of hormonal changes that needs to be quenched irrespective of marital status. In fact, I had adequate knowledge about STD from media but in my own case, I was not so serious about the diseases. The attitude, like any other youngster of my age, was ‘this won’t happen to me’, but now I think I am about to change. Though I live in a society that allows sex with

Film Analysis Update Essay Example for Free

Film Analysis Update Essay I have selected the film â€Å"Elizabeth: the Golden Age† because I became extremely fascinated on why of all the monarchs who have ruled England, she is the monarch that has been included in various forms of literature as well as having an era in England’s history named after her. After selecting the film for this paper, I first watched the entire movie without pausing and just noting down scenes that I considered as the most important. After that I watched the film again carefully so much so that I would pause the film once in a while in order to note down important parts of the film. My next step was to go to the Library and began to study the book â€Å"England’s Elizabeth: an Afterlife in Fame and Fantasy† by Michael Dobson and Nicola J. Watson in order to get a better understanding how authors, poets and filmmakers have depicted Queen Elizabeth I in various forms of literature and productions. The best resource materials I came across were â€Å"Behind the Mask: the Life of Queen Elizabeth I† by Jane Rush Thomas since it gave a very objective outlook on the life of Queen Elizabeth I. In the paper, the summary of the film would first be presented on the paper followed by the presentation of information from resource materials which would either support or challenge certain scenes in the movie, specifically the role of Mary Stuart in the attempted assassination of Queen Elizabeth I and the war between Spain and England. From there a comparison on the accuracy of the depiction of this chapter in the life of Queen Elizabeth I in the film will be analyzed since there were some events shown in the film that appear to contradict historical documentations.

Analysis Of The Leadership Of Kim Jong Il History Essay

Analysis Of The Leadership Of Kim Jong Il History Essay It is believed to be important to examine the life and leadership style of Kim Jong Il for several reasons. Among these reasons are the following. There is much talk about an absolute and/or unquestioning loyalty to Jong Il (e.g. Kang, 2006; Pollack, 2009), and it is deemed important to understand the reason for this. In addition, although North Korea bears the description The Democratic Peoples Republic of Korea, its political ideology appears to be in no way linked to democracy, and it is believed that the reason for this should be investigated. Also, of grave concern is how the people of North Korea continue to remain in submission to the inhumane treatment that they have been receiving, and how they have managed (i.e. despite the atrocities taking place in their country) to maintain the ideology that their homeland is literally Paradise on Earth (Hyun Sik, 2008, p.50). What allows North Koreans to perpetuate the thought that they are living in a chosen land (Hyun Sik, 2008, p.50) ? Does their political leader have anything to do with it? What about his leadership style? This paper is expected to unearth the truth behind the North Korean situation. It is believed to be important to understand the North Korean situation through the image of its leader, because of the nature of his leadership. Jong Il is described as one who has assumed absolute control of North Korea (Kang, 2006). He is what is known as a dictator. Consequently, it is believed that if he were to be properly examined then it may be understood why he is the way he is, how the people of North Korea have been affected by his rule as well as how things may be able to turn around for his country and people. To gain the above understanding, an academic research will be conducted on Jong Il in an effort to be able to assess his life and leadership style to gain the desired result. This research will be conducted in the form of a literature review. First the leaders biography will be presented followed by which his leadership style will be diagnosed and assessed within the context of Nahavandis text book on leadership (i.e. The Art and Science of Leadership, fifth edition). Through an analysis of the literature and Nahavandis text, the parallels between Jong Ils leadership style and the concepts discussed within the text will be identified in order for a critical assessment of the North Korean political leadership situation to take place. This assessment should be what will produce a conceptual understanding of the present political leadership within the North Korean context as well as how this leadership situation not only coincides with what Nahavandi (2009) presents, but also works to a ffect the lives of the North Korean people (i.e. inclusive of its leader, Jong Il, the one in question). A brief history of the leader It is unclear when Kim Jong Il was born as well as under what circumstances his birth took place. Jong Il, according to Pike (2009), was born on the 16th day of February, 1941. AE Television Networks (2009) also stated the same date of birth for Jong Il. However, both Pike (2009) and AE Television Networks (2009), acknowledge that Jong Ils year of birth was subsequently adjusted to 1942. The reason given by Pike (2009) for this change was that the same was expected to necessitate a thirty-year age difference between Jong Il and his father Il Sung. The circumstances surrounding Jong Ils birth remain a mystery. Many accounts have been given of the same. Some of these accounts include the following: Jong Ils family claimed that a swallow foretold his birth; others claim that a double rainbow appeared over Mount Baekdu when he was born, while some even stated that with the event of his birth, a new star appeared in the heavens. All these theories surrounding his birth take root in what is described as a cult of personality, which simply illustrates that legend and official North Korean government accounts describe [Jong Ils] life, character, and actions in ways that promote and legitimize his leadership (AE Television Networks, 2009). Needless to say, whether Jong Il was born in Khabarovsk, USSR or in a secret camp on Mt. Baekdu in Samjiyon County, Ryanggang Province (Pike, 2009), there appears to be something mystic about this leader. If there was not, then why would all of North Korea hail him as the Dear Leader and interpret hi s as well as his fathers existence through an analogy of Jesus Christ and God (i.e. with Jong Il being made to represent Jesus Christ in the minds of the North Korean people, while his father, Il Sung, is being made to represent God in the minds of the same) (AE Television Networks, 2009; Kang, 2006)? As Kang (2006) stated, the people of North Korea literally worship Jong Il just as they worshipped his father Kim Il Sung. One North Korean gave the following account of Jong Il: General Kim Jong Il is a rare great man of Baekdu type who was born at Mt. Baekdu, the sacred mountain of our nation, and made an unusual growth amidst the special revolutionary education of his parents, brilliant commanders of Baekdu, as well as the practical training of the revolutionary struggle. He personifies the revolutionary spirit, trait and nature of Mt. Baekdu. The revolutionary spirit of Mt. Baekdu personified by him is the spirit of independence associated with the soul of Baekdu, the spirit of gun inheriting the linage of Baekdu, the indefatigable revolutionary spirit replete with the mettle of Baekdu and the optimistic spirit consistent with cheerfulness of Baekdu. The revolutionary trait of Mt. Baekdu possessed by him is pluck and courage of Baekdu-style giant, ever-victorious sagacity of the brilliant commander of Baekdu, broad-mindedness befitting a heroic man, organizing ability of leading millions of people, indefatigable attacking spirit, strong ability of executi on (Pike, 2009). As mystic as Jong Il may have appeared, he was seen as one who demonstrated loyalty to his father Il Sung. This loyalty, according to Pike (2009), was demonstrated through Jong Ils involvement of the purging of his fathers guerrilla cronies as well as those who were not deemed personal friends of the Great Leader (Kang, 2006). It is believed that this loyalty to his father is what made him his fathers successor. Jong Il was described as forever being in politics. He was noted as being active in the Childrens Union a youth organization that promotes the concept of Juche (the spirit of self-reliance) as well as in the Democratic Youth League, where he engaged in the study of Marxist ideology (i.e. in relation to politics) (AE Television Networks, 2009). It is believed that in 1974, Jong Il was named the successor of the revolutionary cause of Juche, and that between 1971 and 1980; he was given positions of increasing importance within the Korean Workers Party (Pike, 2009). When Jong Il was named successor to the cause of Juche, he reportedly embarked on an initiative, which saw to the advancement of the program, which was concerned with the imbuing of the entire Korean society with the Juche ideology (Pike, 2009). Kim Jong Il reportedly had an interest in many disciplines, none of which he was particularly good at (Hyun Sik, 2008). One of the disciplines Jong Il was interested in was the arts. He was described by AE Television Networks (2009) as the overseer of the Propaganda and Agitation department in his country. This department was the one responsible for controlling the media as well as for censorship (AE Television Networks, 2009). As leader of this department, Jong Il reportedly used the mass media, literature and art, all media that fall under the umbrella term popular culture, to stretch his public image as well as to obtain popular support for himself (Pike, 2009). When Jong Ils father died in 1994, Jong Il reportedly assumed supreme power over the North Korean state. It is through this acquisition of power that Jong Il à ¢Ã¢â€š ¬Ã‚ ¦micro-manages every detail of government business (Pike, 2009). Pike (2009) describes Jong Il as being opposite to his father. He is described as being impatient as well as a vivid displayer of extemporaneous behaviours. Jong Il is described as being arrogant and self-centered in policy decision making, unappreciative of criticism as well as opposing opinion and emotional when it comes to displaying his likes and dislikes (Pike, 2009). However, on his softer side, Jong Il is known to be a lover of movies (e.g. James Bond movies) and is known to have a personal collection of films in excess of 20000 (AE Television Networks, 2009). Nevertheless, despite the latter, Jong Il can be thought of as a sad case, because his legitimacy as ruler of North Korea is determined by the said countrys political system. As a result, Jong Il remains prisoner to a system into which he was born. There is nothing Jong Il could do to reform his nations political system without undermining his own legitimacy. Therefore, his only rational option is to uphold the system (P ike, 2009). Jong Ils upholding of the system is notably in the best interest of his country. A critical assessment of the life and leadership style of Kim Jong Il Kim Jong Il, on the basis of his biography, can be deemed a charismatic leader. However, he is of the unethical type. He is deemed a charismatic leader because he shows forth characteristics such as a high degree of self-confidence (expressed through his firm belief in his ideology), strong convictions about his ideas (which is based on him being unaccepting of criticisms as well as opposing opinions), expressiveness (manifested through his description of being an emotionally expressive individual) as well as activeness in image building (expressed through his use of popular culture to expand his popular image) (Nahavandi, 2009; Pike, 2009). However, although the above is true of Jong Il, he is also deemed to be unethical for several reasons. Jong Il is noted to use his power for personal gain or impact and to promote his personal vision (i.e. through the use of the Propaganda and Agitation Department), to censure critical or opposing views (i.e. through his unaccepting of them), to demand that his decisions be accepted without question (as manifested through the unquestioning compliance spoken of by Kang, 2006), to use one-way communication, and to be insensitive to followers needs (accounted for through Kangs description of the sufferings that the people of Korea are made to endure at the hand of Jong Il) (Howell Avolio, 1992). Although Jong Il uses his power indiscriminately, he can still be considered an effective leader. This is because based on the circumstances in his country; he uses his power to maintain the stability required for the effective functioning of the same. It may not be the view of many outside of North Korea. However, with the level of brainwashing the people of that land have received nothing seems wrong for most of not all. As it was noted earlier, even though Jong Ils leadership style is not the best, he has no choice than to ensure that it is perpetuated. This is because if he chooses to change the way his authority is ascribed to him (i.e. to reform the political system in his country); he will be doing himself more harm than good. As Pike (2009) described, Jong Il is a prisoner to the system; a prisoner in that even if he wants to change the system, he would not, because of the unwillingness to give up his supreme, divine status. It is what grants him his legitimacy as political l eader of North Korea, and it therefore cannot be changed without upsetting the present leaders legitimacy to rule over the state. Jong Il can therefore be placed within the context of the contingency era of leadership. This is because as Fiedler describes, his effectiveness as a leader is based on a match between his leadership style and the leadership situation (Nahavandi, 2009). Jong Il is effective as a leader because his leadership style matches his leadership situation (Nahavandi, 2009). Jong Ils leadership personality can also be interpreted in terms of the behaviorist perspective. It can be thought that Jong Il was trained to be the type of leader that he is. His father, Il Sung, ensured that Jong Il was groomed in a particular way from young. He (Jong Il) was made to attend specific schools; namely, Namsan Primary School (a school he later destroyed through bombing), Namsan Higher Middle School, and Kim Il Sung University (AE Television Networks, 2009; Hyun Sik, 2008). According to Hyun Sik (2008), these schools (afore mentioned) were reserved for the elite of the North Korean society, in particular, party officials above the rank of vice minister (p.47). At these schools, the concept of Juche was taught. Apart from attending these schools, Jong Il was able to nurse the Juche ideology from being in close contact with his father as well as through his involvement with the Childrens Union. Consequently, he was able to perpetuate its existence. Jong Il believably lea rned to be a dictator, an autocratic, because as his former instructor described, he was a shy young man (Hyun Sik, 2008). But what made him acquire this leadership personality? It is believed that Jong Il was predisposed to acquire certain behavioral characteristics that would have allowed him to be an effective leader today. It is believed that Jong Il was exposed to a great deal of charismatic experiences throughout his early life. As a result of this it is assumed that he has adopted a certain degree of charisma and that this very charisma is what he was able to use to sway the minds of the Korean people in the direction that he wanted them to go. Jong Il, because of his ability to manipulate the minds of the North Korean people, through the channel of indoctrination, as accounted for by Lankov (2007), can be described as an individual who scores high on the Machiavellian personality scale. Jong Il and his parents crafty use of supernatural accounts at the time of his birth were used to convince the people of North Korea that Jong Il is a deity. Consequently, the North Korean people found themselves worshipping Jong Il in much the same way as they worshi pped his father (Kang, 2006). Apart from Jong Il being made to look like a deity, he reportedly did all in his power to keep the people of North Korea thinking and acting in a particular way, a way that would ensure the continued legitimacy of his power that flows from his position as Supreme Leader/Ruler of the DPRK. For example, as stated by Lankov (2007), North Korea has maintained a self-imposed information blockade that is without parallel (p.71). North Koreans are not allowed to have free tuning radios, neither are they allowed to listen to news casts and programs that are from sources outside North Korea. This news blackout is supposed to keep North Koreans believing that their country is an earthly paradise (Lankov, 2007, p.71). In this way, North Koreans will cast a blind eye upon the inhumanities that Jong Il is said to bestow upon them, because they supposedly do not know any better. In other words, their reality is based purely on what Jong Il feeds them. So, although North Koreans may feel in their h earts and minds that something is wrong with the political leadership in their country (if even they do), they will continue to exist within a false reality, because of the unadulterated doctrine, which has been ingrained deep within their psyche. Continuing on the subject of power, the other sources of power that Kim Jong Il possesses is that of Coercive Power and Reverent Power. Nahavandi states that coercive power is the leaders ability to punish; persons comply for fear of this punishment. Kim Jong Il exercises his Coercive Power by ensuring that he attains full compliance from the people by instilling fear in them by threatening to arrest persons who refuses to adhere to his directives; deeming them political criminals. Jong Il also received Reverent Power through his coercive tactics on his people. He did this by mandating the people to worship him and his father and demanded that all believed and followed the principles of Juche. So not only was he their political leader her was their spiritual leader qualifying his Reverent power. Jong Il is accused of committing many heinous crimes against the North Korean people. Kang (2006) argues that he should be charged for crimes of war as well as of genocide. Kang (2006) argues that although Jong Il may not commit these crimes himself, he (in one way or another) sanctions them. Kang (2006) was careful to mention that the people of North Korea were mistreated on the basis of their religion and nationality. Christians and what were described as half-Han Chinese infants fathered by Chinese or other non-Koreans fell victim to Jong Ils rule. Women, who fled to China and got pregnant there, and were later forced to return to North Korea, were forced to have abortions. In the case of religion, any one who was deemed associated with any other religion besides Juche was persecuted by Jong Il. These persons were typically those who fled to countries outside North Korea seeking refuge, and were suspected of being influenced by outside intervention. However, unfortunately for th em, they were forced to return to their home land (Kang, 2006) where they paid the ultimate penalty for their supposed spiritual fornication. According to Kang (2006): One person testified that she saw prison security officers kill several Christians by pouring molten iron on them after they refused to renounce their religion and accept the state ideology of Juche. In particular, members of underground Christian churches and persons in contact with Christian missionaries have been subjected to harsh punishment, prolonged detention without charge, torture, or execution (p.99). Jong Il is so adamant about his belief in Juche that he went to great lengths to gain compliance from all persons dwelling within his territory of rule. Kang (2006) stated that the citizens of North Korea were literally mandated to worship Jong Il and his father based on what was known as the Ten Great Principles of Unique Ideology. Persons failing to comply with this order became political or ideological criminals and were made to suffer much abuse (inclusive of rape and the deprivation of food and medicine) (Kang, 2006). No one was spared the wrath of Jong Il from the smallest and most innocent of children to the oldest of adults, were made to suffer the consequences of their perceived defiance to Jong Il. For example, it was noted by Kang (2006) that Jong Il punished a nine year old and his family, because the child innocently scribbled over the faces of Jong Il and his father Il Sung that were printed in his text book. Neither the child nor his family was ever seen again; they l iterally vanished off the face of the earth. The interesting thing about Jong Il is that he ensured that he was awarded compliance from his citizens by instilling fear in them. Kang (2006) noted that In addition to [a] cult-like mentality [existing in North Korea], a culture of surveillance pervade[d] [the] North Korean societyà ¢Ã¢â€š ¬Ã‚ ¦ (p.56). Every individual was literally placed as each others watch man to ensure that each individual was living according to Jong Ils rules and/or orders. The Peoples Security Agency, the State Security Protection Agency, and the Korean Workers Party each plant[ed] their own informants in all work-places and units of organization', and since no one knew who exactly was an informant, they were all forced to be on their Ps and Qs (i.e. to be on their best behavior) (Kang, 2006). All these efforts to ensure forced compliance to Jong Il illustrates that the North Korean leader is definitely a high Mach because he is more than willing to do whatever is necessary to gain his desired end (i.e. e ven though it means manipulating other people [as he evidently did] or gaining his desires at the expense of other individuals). From the preceding essay, it can be deduced that Kim Jong Il is definitely the leader of a brutal dictatorship. He displays qualities of an autocrat, because he makes decisions on his own (i.e. without being opposed). The literature exposed him as one being intolerant of criticism and disfavoring of opposing opinions. Jong Il was described as a leader to which there was an unquestioning loyalty. Everything he ordered was executed by his subordinates (i.e. the people over which he ruled) without question. This occurred irrespective of whether the actions were right or wrong. Jong Il was termed a high Mach because he was seen as one using the legitimacy of his power to manipulate his followers into doing precisely what he wanted them to do (i.e. without care for how his desires were affecting the persons directly involved). Jong Il utilized fear tactics to ensure that he gained the compliance he required another indicator that he would score high on the Machiavellian personality scale. Apart from severely punishing people for defying him, he placed the North Korean people against each other by making them all spies for him. The North Korean leader appeared to be a possessor of charismatic qualities (i.e. he was deemed to be one born with special qualities for a special purpose). His birth was described as supernatural in occurrence, and the activities surrounding his birth were used as a tactic to gain the desired support from his followers. Jong Il, despite his negative qualities, appears to be an effective leader because he is able to maintain the stability required in his country. He appears to be operating under the contingency model of leadership because his leadership style appears to be directly related to his leadership situation. However, although Jong Il appears to be an effective leader, he is one that is unethical for various reasons. For example, Jong Il is noted to use his power for personal gain or impact and to promote his personal vision, to censure critical or opposing views, to demand that his decisions be accepted without question, to use one-way communication, and to be insensitive to followers needs all actions that are unethical by Howell and Avolios standards. Jong Il appears to be an explicit case of the nature/nurture principle. He is believed to be endowed with certain character traits (e.g. influence and/or charisma) nature that together with his ideology (Juche) and/or trained behavioral characteristics (authoritarianism or dictatorship) shapes his leadership style nurture. Jong Ils personality and leadership style have created a North Korea that sparks immense interest from the outside world. Apart from them being interpreted as treacherous, it is still unfathomable how the people of North Korea, at the hands of one man, can live to accept such an inhumane political system, and comply with it unquestioningly. Could this be a case demonstrating the share power of indoctrination or is it that North Koreas leader has emerged to be so powerful and feared, because his society provides the grounds for him to do so? Some food for thought.

The Important Role of News Reporters Essay -- Exploratory Essays Resea

The Important Role of News Reporters Every morning when I get up, the very first thing I do is turn on the TV--but not for cartoons or MTV. It has become a habit for me to watch the news in the morning. I feel the need to know what is going on because I know that no matter where the news happens, 99 percent of the time it will, directly or indirectly, affect me or people I care about. The broadcast media has become a part of my life and the lives of almost everyone in the Western world. We may not know the names of our senators, but Katie Couric or Tom Brokaw are familiar names in every American household. Not many of us realize, however, that the job of the news reporter is not as glorious as we imagine. This paper will offer you a closer look on what goes on behind the TV screen or radio microphone. Like all other discourse communities, news reporters have their own jargon. It consists mostly of technical terms describing different aspects of news production. In radio, there are voicers, readers, Q&A's, and packages--all of these are types of stories. Voicer is a news story voiced by a reporter; reader is a script of a news story read by a news anchor; Q&A is an interview; and package is a news story produced and read by a reporter that also includes parts of interviews or natural sound. A particular feature of a news reporter's jargon is that very often there are a couple of different terms for one concept. For example, other words for "package" are "wrap" and "feature"; "cut," "bite" (or "soundbite") and "actuality" all refer to a part of an interview. But in most cases, the jargon of the news reporters is much more understandable to an outsider than, for example, the specialized language of chemists.

Method For Characterisation Of Laser Beams Engineering Essay

Particularly in the field of optical maser direct authorship lithography it is necessary to derive exact cognition about the form and features of the used optical maser beam, whilst a homogenous power distribution is an indispensable parametric quantity for qualitatively good and consistent consequences in surface structuring. Several â€Å" classical † methods in word picture of optical maser beams are already applied, such as: Knife border method Slit method Pinhole method CCD camera method These techniques will be shortly explained in subdivision 2. In fact, a optical maser beam ( â€Å" standard TEM00 † ) fades bit by bit, due to its Gaussian profile ( Figure 1 ) . Therefore it is necessary to find what is known as the Centre of the beam. Chapple [ 1 ] describes the strength profile I ( x, y ) as follows: where ten and Y are the cross Cartesian co-ordinates of any point, x0 and y0 mark the Centre of the beam and R is the 1/e2 radius. This definition is frequently used in theory. McCally [ 2 ] defines the Gaussian distribution of the strength I ( x, y ) by agencies of the beam radius R belonging to the 1/e irradiance shown in Figure 1 ( left ) . The emitted power of the optical maser beginning can be determined by incorporating the irradiance ( I ) , severally the optical strength I ( x, y ) , over the affected cross sectional country A:2. Techniques of beam profilingKnife border method To derive information about the power distribution across a cross sectional plane of a optical maser beam, the use of the knife border method is the most simple attack. Thereby, a crisp edged home base, e.g. a razor blade, is ab initio covering the whole optical maser beam in forepart of a power metre for continues wave radiation or an energy metre for pulse operation. By precise line wise supplanting of the knife border mounted on a additive motion phase, more and more optical maser radiation reaches the detector unit, until the whole beam is covering the feeling country. Figure 1 ( right ) shows the consequence of this measurement process: Due to the motion of the knife edge the value of the detected power additions steadily. The derived function of this power map P ( x, Y ) yields the two dimensional Gaussian profile of the power distribution across the optical maser beam ( Figure 1, left ) . Slit method A 2nd possibility to find the power distribution within a optical maser beam is similar to the knife border method: Alternatively of a crisp edged home base, a really narrow slit is step by step moved across the optical maser beam. As a stipulation for valid measurings the gap of the slit has to be smaller than the diameter of the considered beam is. Typically this gap is in the scope of some micrometers. Drawbacks of â€Å" traditional methods † The knife edge- every bit good as the slit method offer merely a limited measure of beam features: local â€Å" hot-spots † , i.e. countries of superior power, are undetectable due to the incorporating measurement rule. However this method is suited for speedy measurings to find the diameter and the class strength profile of the considered optical maser beam. Pinhole method This method measures the strength of irradiance through a really little hole in a home base ( pinhole ) confronting the optical maser beam. The strength of light go throughing through this pinhole is instead low, so that a photomultiplier tubing ( PMT ) has to be used to observe the irradiance. Due to the feature of a PMT, e.g. its comparatively low signal to resound ration ( SNR ) , the collected informations are corrugated. However the strength distribution can be achieved within a local declaration of about 3micron by using a Gaussian tantrum. Therefore by transversal scanning across a optical maser beam, a high declaration image of the power distribution within the beam can be gained. Hot musca volitanss are noticeable and more elaborate characteristics can be located. CCD Camera method Differing from the scanning methods described above, the use of CCD ( Charge-coupled Device ) cameras for the review of optical maser musca volitanss will give a really speedy feeling of the power distribution within the beam by merely a â€Å" individual shooting † . The quality of the image, e.g. the declaration, is straight depending on size and figure of pels on the CCD-Sensor-chip. Typically the pel size is in the scope of 6 microns2, linked to a entire figure of pels in the scope of 1 to 2 mega pels. By utilizing this method it must be noted, that dust and other drosss on the CCD bit can ensue in image deformation and/or misinterpretable beam characteristics. Furthermore, attention must be taken non to destruct the CCD bit by the incident optical maser beam.3. Beam word picture by agencies of optical fibers tipsTo get the better of the limited declaration of the CCD- and pinhole method, severally, a new strength profile measuring technique has been developed. Similar to the pinhole method described above, an optical fiber tip with an aperture of a few 100 nanometer is applied to roll up light by scanning across a optical maser beam transversely. A photomultiplier tubing ( PMT ) attached at the out-coupling terminal of the fiber detects the gathered visible radiation during the scanning procedure so that a two-dimensional image of the strength distribution can be evaluated. By altering the sidelong place of the fibre tip, multiple cross sectional planes can be scanned, taking to a three-dimensional image of the strength distribution e.g. within a focussed optical maser beam.3.1 Near-field matching into the optical fiberâ€Å" Classical † attacks to picture the incoupling of visible radiation into the fibre tip fail, due to the really little gap of the fibre tip ( aperture ) , in the scope of some hundred nanometers, which is considerable smaller than the wavelength of the optical maser visible radiation within the focal point. Due to this really little gap, one can speak about the so called â€Å" close field † To derive information arising from the close field and to transport this information into the far field, it is necessary to transform the evanescent Fieldss into propagating Fieldss. This could be done by seting a Centre of dispersing, in this instance the really narrow tip, into the close field. Thereby dipole- oscillations are generated at the boundary of this tip by agencies of the evanescent field ( Figure 2 ) . With: I µ0= vacuity permittivity ; =unit vector ; = wave vector: 2/ I » ; I†°= angular frequence of the oscillation and utilizing the dipole-moment: With: a=diameter of the gap ; I µr=relative permittivity The undermentioned footings for the far field ( R & lt ; & lt ; I »/2 ) and the close field ( R & gt ; & gt ; I »/2 ) can be derived, and one gets not-propagating every bit good as propagating field constituents: Respectively: The propagating field is straight linked to the close field and can be detected afar. The simulation of the electrical field generated by a plane moving ridge of 1 V/m, heading to a fibre tip, is shown in Fig 3. Based on an optical power of 10mW dispersed on an country of 1 square micrometer, ( which is a instead large country ) , one get by utilizing: with: I= Optical Intensity ; S=Pointing vector ; v=velocity ; E0=electrical field ; D0= electric initiation denseness ; n= index of refraction ( here air: 1.0 ) ; I µ0= vacuity permittivity ( rounded: 10-11 F/m ) = 1010 V/m It has to be noted that the field within the tip is exponentially diminishing ( refer to formula N ) and by this merely a really little portion of the generated electrical field, in this illustration 5*1010 V/m straight at the tip, can be detected at the out matching terminal of the fiber by the PMT.3.2 ApparatusThe PI P-854.00 piezoelectric actuator used in this apparatus has a displacement scope of 25A µm for all right placement and can besides be pre-positioned by a micrometer-screw more approximately. The sensing of gathered visible radiation is done by a Hamamatsu H5784 type photomultiplier tubing ( PMT ) with an E5776 FC type adapter attached ( Figure 4 ) A fibre holder mounted to the piezoelectric actuator is used to take and protect the optical fiber tip during the scanning procedure. After elaboration ( x10 by transimpedance amplifier phase ) and filtering of the gathered strength informations it is converted into digital informations by agencies of a National Instruments 6025e PCI interface card.3.3 Fibre tip productionFor this application the optical fiber type used to bring forth the tips is a individual manner fiber manufactured by Newport. Its cut-off wavelength is optimised for the usage of optical masers in the wavelength scope of 400nm -500nm. There are two possibilities to develop the conelike tip of an optical fiber harmonizing to the petitions of a Scaning close field optical lithography ( SNOL ) – fibre tip: The optical fiber tip can be realised by: Pulling methods Chemical etching During the pulling process the optical fiber is preloaded before it is heated up locally with a CO2-laser or a heating-film and forced to run. As the thaw procedure begins, the puller stretches the optical fiber with extra force apart, so that the fiber is tapert first and eventually cryings itself bring forthing two tips. The belongingss of the optical fiber tips produced this manner vary on the different parametric quantities of the puller – as for illustration the drawing force. Normally, all pulled SNOL-tips show a really thin geometry ( e.g. Figure 4, left ) . This is particularly disadvantageous for the considered application, because this thin construction tends to flex and hover. More stiff fibers, which have tips with higher cone angle, are more suited Furthermore, these fibers tips feature a really little transmittal of 10-5 to 10-6 due to the long form of the tip, in which the visible radiation is evanescent ( exponentially diminishing ) . Larger cone angles and correspondingly a higher transmittal up to 10-2 is reached by engraved SNOL- fiber tips as used in this work. Several etching methods exist to bring forth fibre tips. The process used here is the so called â€Å" tube-etching † . After cleansing of the optical fiber by agencies of ethyl alcohol, the fiber is immersed into hydrofluoric acid. ( Figure 5 ) The undermentioned chemical reactions take topographic point to the Si contained in the fiber – and/or with the Ge at doped fibers: Tube-Etching is a farther development of the standard etching-method, invented by Turner in 1984, published by Stoeckel et Al. and Lambelet et Al. [ 4, 5, 6 ] This process improves the production of well smoother tip surfaces. At the tube-Etching process the coating of the optical fiber is non removed before the etching procedure. Due to gravity drawn debasement of the glass merchandises, a concentration incline arises in the hydrofluoric acid, which causes convection. The convection carries the hydrofluoric acid into the upper zone of the tip that develops therefore conically. To forestall corrosion by hydrofluoric acid exhausts at the upper parts the fiber, a light mineral oil was used as a dissolver to gain a separate stage above the hydrofluoric acid. The temperature during the production of the tips corresponded to room temperature. By completion of the tube-etching procedure the coating of the optical fiber is removed by dichlorine methane and the tip can be metallized, go forthing a little aperture.4. ConsequencesA trial rig has been build utilizing optical fiber tips for automized three-dimensional strength profile scanning ( Figure 3 ) . With this it is possible to derive information about the spacial power distribution within optical maser beams. Due to the little aperture of the fiber tip even really little focal parts can be profiled with high local declaration. Corresponding package was developed to command the traveling x-y phase, every bit good as the omega actuator automatically utilizing LabviewA © . Therefore, it is possible to scan acro ss the optical maser beam tomographically, while roll uping strength informations. The information can either be displayed or visualised by agencies of the scanning package itself. Using a new developed package based on OpenGlA © , the strength informations can be displayed in a 3 dimensional image ( Figure 7 ) with the chance to revolve the way of position in all grades of freedom. Furthermore, different mathematical filters can be applied to better image quality. By scanning more transverse sectional planes, individual pieces can be shown in an â€Å" overlayed † manner, to detect the focal point â€Å" traveling † due to the sidelong alteration of the fibre tip ( Figure 8 )3. DecisionA fresh method for high deciding beam word picture particularly for little aperture optical masers has been described. With this automized 3- dimensional series scanning method it is possible to derive information about the spacial power distribution within a optical maser topographic point.4.
