Leadership and Employee Relations

As a leader have been described as having the patience of a Saint and that I encourage free thinking. Turnover has been low for me as It was for the supervisor before me was the same type. While staff relations are not quite harmonious, they will support each other when needed. I find it difficult sometime because I have come to the conclusion not everyone has a natural desire to work hard for what they want. This makes It confusing to understand those who do not give 100% to achieve the job goals.This will be a study of how to improve employee relations. Improving employee relations can be done by bringing morale up through effective and open communication. The supervisors ability to address concerns and to follow up on those concerns; and by setting the example will give the employee a feeling of worth. It is also important for the supervisor to show support for better or worse the employee's actions.Delegating tasks Is not by Itself empowerment but giving guidance and encouragemen t and the willingness to support the employee whether the outcome was ideal or not (Weiss, Suppose, Volvo. 72 Issue 9). It is important to give employees praise and recognition for the work that they do, people like to hear when they are doing a good Job. When the only recognition heard is the pointing out of errors It brings down morale and people's work start to suffer. This writer also states that actively listening with feedback not only clarifies what is being said but also shows empathy.Motivation can be difficult but some ways that may help is: to make sure employees have all the tools available to do a good job, recognize those employees who do a great Job, being friendly and enthusiastic can ester a better atmosphere, get input from employees to find better ways to complete a job, act quickly on complaints, avoid favoritism, and most important is for the supervisor to spend time in the workplace (Weiss, Suppose, Volvo. 72 Issue 9). The manager working side by side with the employees shows an Interest In what they do and the manager shows firsthand experience In the department.I notable ten development AT poor employee relations rater taking ten position AT supervisor. The department had gone for 6 months without a supervisor and then I as promoted to the post. We had been working as a team to fill in the slack with the loss of our supervisor, pulling extra shifts, doing inventory, making orders, and creating schedules. Even though I had said thank you to them after receiving the posting it was not what they were looking for. As I had been one of the ones filling in on extra duties, what they wanted to hear was some acknowledgement or thank you for doing so much for so long.It never came, now I believe if it were it would not make things better as it has been over a year now. This is what has sold me on paving praise and acknowledgment when it is due. There have been studies to support this, when employees are poled on what is important in their Job be sides pay and chances to rise, they feel the need for praise and acknowledgement (Assonance, Octoroon, Volvo. 44 Issue 2). Some of the most successful businesses are those who offer employee perks and recognition as individuals. Fell-Pro of Cookie, Illinois has never had a labor dispute or a work stoppage in 68 years.They attribute that to giving their employees extras and the recognition of each as an individual. Besides the normal financial extras that can come from a company, they have monetary recognition such as posting on an electric sign board of birthdays, anniversaries and congratulations for all to see (Articulation, Jug, Volvo. 75 Issue 7,). Recognition is a big part of morale which has a direct effect on employee relations. Unhappy employees make unhappy workplaces and that is bad for the employee and the business. Low morale starts people looking for new Jobs, someplace that is more pleasant to work.

Other Forms Of Social Control

All societies impose social control on their citizens to some degree. This type of control allows them to monitor and regulate behavior formally and informally. Key’s to understanding a culture’s system of social control is having a better understanding of the social norms. In large scale society they maintain social control within the legal institutions.There are also two other major controls that exist that many are unaware of. Religion is known to have control over the population, the public and the behavior of all. Whenever a person claims to be a dedicated Christian they must follow certain types of moral codes in order to uphold the personality in the public.Television is another form of social control. This control was noted that television was blocking mostly those individuals from enjoying the life on the outside of their doors. Social control is even in our households. A person wants their household a certain type of way has somewhat of a social control.I am u nder the impression that when a child is growing up they are taught wrong from right, what is good and what is bad. This however is only to prepare them for the real world.The subconscious mind is an outstanding and powerful information processor that can record and replay events that happened in the past. However many individuals become aware of their own subconscious mind when they realize they’re engaged in an undesirable behavior only as a result of someone who has pushed the wrong buttons.

MACRO AND MICRO ECONOMICS Assignment Example | Topics and Well Written Essays - 1000 words

MACRO AND MICRO ECONOMICS - Assignment Example During their climax, copper was very costly in the global markets to an extent some coins made of copper were more worth than their face value. The following discussion will address the trends in the global markets of copper, their distribution and demand and ways in which the government can influence the price, demand and supply of copper. The Main Economic Trends and Features of the World Copper Market During the Period 2007-11 The United States local production and use of copper has slightly gone high in 2011 to a figure of about 1.1 million tons raising its value to approximately $ 10 billion. Montana, Nevada, New Mexico, Utah and Arizona in the ascending order of production contribute over 99% of the local mine manufacture. Copper that was refined used about 30 mills of brass, 15 mills of rod and 500 foundries and sundry end users. Copper and its alloys were consumed in the building infrastructure where about 45% were used in electronic goods, 23 % consumed in the equipment of t ransport, 12 % consumed in general products similar to the consumer goods while the industrial ware used about 8% (Ho & Yi, 2008: 538). Between the years 2007-2011 the unproduced import sources from Chile was approximately 42 %, the Canadian was about 33 %, Peru amounted to 13% while Mexico had 6 % . The unwrought copper imports comprised of 83% of the refined copper. There has been an upward trend in the prices of refined copper in the second of half of 2010 with the ending year price according to London Metal exchange reaching a record high of $ 4.44 per every pound of copper (Botchway, 2011: 355). Even though the prices have been fluctuating considerably, the price of copper has remained over $ 4 per every pound throughout August 2011 with a record high price by LME going way up to $ 4.60 per pound in February 2011. In the month of September 2011, in reaction to the crisis regarding the impact on the demand of copper from the increasing debt in the European Union and the slowing development policies in the Chinese republic, the spot price fell acutely to about $ 3.16 per every pound in the course of week 1 which was the least since 2010 July (Gleich, Ayres & Go?Ssling-Reisemann, 2010: 121). The Factors Which Led To Change in the Demand for Copper during 2007-11 However, in September, the global copper research group predicted that the world’s refined demand of copper in 2011 would go beyond the production of refined copper by approximately 200,000 tons which would elongate the deficit production that occurred in 2010 as predicaments of operations and labor unrest inclusive of the strikes in Chile and Indonesia. This would continue to strain the global output of copper mine. The global demand, consumption and production of refined copper was estimated to go high by 1.5% and 2.3% by 2011 (ILOTTMMOTCM, 2008: 14). The production in the U.S mine went up abet in 2011 as restoration of mine restrain instigated at year end 2008 were majorly counterbalanced b y a less Ore Grades at a chief producer. The production at the electrolyte refinery went down due to closure of the refinery that was experienced in 2010 that eventually treated trade in anode and to less local output of smelter, the latter leading to a high degree of exports. The Copper mine production in the United States was projected to increase by over 100,000 tons in 2012, fundamentally because of the increasing refurbishment of cut downs. The local consumption of refined copper was close to unvaried in the year 2011 (Geological Survey, 2011: 21). Moreover the boom in the construction sector in China has also granted the consumers an insatiable

Review - Research Paper Example With a sound Quality Assurance in place, customers and end users of products and services of a particular company is guaranteed that its output conforms with the required quality of such product and service that will meet and exceed the customer’s need. Kaizen is a Japanese Quality Assurance system of continuous improvement in quality, technology, processes, company culture, productivity, safety and leadership. It is a system that involves every employee - from upper management to the cleaning crew. Everyone is encouraged to come up with small improvement suggestions on a regular basis. This is not a once a month or once a year activity. It is continuous quality improvement process. Japanese companies, such as Toyota and Canon receive a total of 60 to 70 suggestions per employee per year which are written down, shared and implemented (Anon., 2011). The limitation of Kaizen is that it is dependent on communication due to the nature of its system improvement coming from suggestions. Any breakdown in communication will impair its efficacy. TQM on the other hand is a comprehensive and structured approach to organizational management that seeks to improve the quality of products and services through ongoing refinements in response to continuous feedback (Anon., 2011). TQM requirements may be defined separately for a particular organization or may be in adherence to established standards, such as the International Organization for Standardizations  ISO 9000  series. At its core, Total Quality Management (TQM) is a management approach to long-term success through customer satisfaction. In a TQM effort, all members of an organization participate in improving processes, products, services and the culture in which they work (Anon., 2011). TQM as a matter of quality principle is not known to have limitation but only the employees who are implementing it. C. The main

Improper storing of private data that were only to be found on the servers by the end users and transmission some sensitive business information between servers and clients. For the proper communications of these findings, some policies were formed up by WWTC in the areas. These plans comprised of internet connectivity that was to be separated by the network, classified system; this ensures physical security to prevent any unauthorized access to the detailed information. The other policy introduced was a wide area network. The system made sure that any data that cross wide area network link has to undergo a protection section such as the virtual private network (Berger, 2012). Public servers was another policy initiated, this ensured that configuration of all public servers using Hypertext transfer protocol system connections and acceptance of all valid requests and pass them through the firewall. Site-to-site virtual private network tunnels were also among the policies that were put in place through the findings enabling mutual authentication and protection to all provided devices (Bansal, 2015). WWTC ended the plans with user education whereby they created awareness and training programs on threats and good security practices. Recommendations gave some deliverables on the general approach that the project may take. Among the recommendations pointed out were The protection of valuable assets of the company, determination of general architecture of the organization and development of a list of specific policies that could be applied and along with the rationale. Specific details must be written. Selection of the 12 relevant procedures for the addition in the Security Policy Document has to be reviewed in the written policies (Bansal, 2015).

The essence of history Essay Example | Topics and Well Written Essays - 750 words

The essence of history - Essay Example Although others have criticized historians for basing their work on hearsay, in a society that expects the purposes of education to serve the general public, the aims and objectives of history can seem a bit cumbersome to define compared to other disciplines such as medicine and psychology. The subject is therefore very useful, although the historical study products are not tangible and in effect not very immediate as opposed to others such as medicine. Significance of History History is known to offer rich source of information in regard to how individuals and the society in general behave. It is very challenging to understand how people and societies operate, though numerous disciplines attempts to do so. Any efforts in knowing what transpires in the society can be hampered by relying only on current data. For instance, it is not easy to evaluate war if a nation is enjoying relative calm and peace. In order to do so, the only way possible is through digging deep into historical dat a. It is not possible to understand our geniuses such as Aristotle, the development and impact of technology as well as the role played by beliefs in determining the course of societal life (Evans, 23), Man therefore must make use of the past experiences to fully understand his environment. As evident, both social and physical scientists have tried to come up with theories to explain the behavior of human persons, but as matters stand, even the recourses needed for such studies largely depend on historical information, except for a few cases where artificial cases involving experiments can be instituted to determine the action of individuals. The main aspects of the operations in the society, namely military incursions, activities of missionaries and others cannot be instituted as laboratory experiments. However history, though riddled with imperfection must serve as the critical laboratory, thus information from the past forms the basis of the significant evidence in the quest to e xplain the many concepts. This is one of the fundamental reasons why man cannot assume the role of history as it provides the most extensive evidential parameter for the analysis and contemplation of functioning of the society. The position of history in the society cannot be underemphasized follows on the already stated significance. It is in order to note that the past determines the present and as well the future. For example, in pursuit of knowledge to get equipped with what happened a century ago, what matters first is to carefully look for what prevailed during the period. At times recent historical developments may come to the fore to offer explanations in relation to some remarkable developments, but above all, it is important to look further in the historical aspects to comprehensively identify what really transpired. It is only through historical studies that man can have substantial knowledge of the changing world, thus the full understanding of societal elements. The sig nificance of history in understanding and explaining the occurrence of change in relation to human behavior cannot be underestimated. For example, alcoholism as a human phenomenon has been a subject of discussion and research. Biological experiments have attempted to identify specific genes that are believed to cause an inclination toward addiction to alcohol in some people. Although it is a laudable scientific advance, as a social reality,

Impacts of Emotional Intelligence of leaders on job satisfaction and Essay

Impacts of Emotional Intelligence of leaders on job satisfaction and Turnover Intentions of followers 02141 - Essay Example Job satisfaction among its employees has been a fundamental reason of the turnover problem as research conducted by Brunetto et al. (2012) suggests. Conversely, whenever an organisation is committed to emotional intelligence, it becomes easier for its employees to be motivated. In fact, Trivellas et al (2013) found that organisational commitment determines the satisfaction of the staff, hence influencing the turnover intentions. In light of these facts, it is highly recommendable that a research be conducted to find a way to mitigate the situation. Therefore, this research intends to analyse the impact the emotional intelligence of leaders has on job satisfaction and subsequent turnover intentions on followers. Credible statistics have proved that Job Satisfaction (JS), Emotional Intelligence (IE) and Turnover Intentions (TI) are firmly intertwined. In essence, it means that none of it can be overlooked or given more attention that the other (Ganzach and Fried, 2012). Unfortunately, this is not something that many business owners have noticed, but rather they tend to focus on the TI without a decisive action to investigate the root problem (Siddique, 2014). Consequently, this approach has proved to be a dilemma for many business owners. For this reason, it would a grievous mistake not to identify these issues and deal with them conclusively. Corporate play an important role in creating employment thus any issue that could prove to be a hurdle ought to be assessed and dealt with early. The proposal will highlight the underlying issues in the three aforementioned areas. In addition, it will offer the concerned parties an opportunity to find a solution in a bid to continue guaranteeing profitability, which is possible through maintenance of a motivated, satisfied workforce. As stated above, the research seeks to understand and bring into the limelight the issues that influence JS

Learning Objectives Essay Example | Topics and Well Written Essays - 500 words

Learning Objectives - Essay Example This is why I want to seek out a better understanding of development from a leadership perspective both in economic and social terms. While we know that development has a social benefit, with a leadership role, the economics of development also become an important consideration for those who choose to take up this field. Secondly, development is a field which has been modified significantly in both national and international terms ever since it was first created as a separate discipline. Just by looking at the list of journals and magazines related to development one can see that the advances made in the field have to take their guidelines from many different sciences including sociology, psychology, science, computer technology and statistics. This points us towards the fact that the field is growing and the latest developments in the field as well as understanding their application is very important for those who wish to take leadership roles in development. Finally by learning and examining the practices which worked in the field as compared to those which did not, I hope to learn the best practices and methods which have been successfully applied. Although there is never a miracle pill solution for all problems of development but by knowing the solutions which worked a person can come to certain conclusions about what may also work in a given situation. This is also a learning objective for me since I wish to know how to spot solutions for development problems by understanding what developers in the past have worked with and how they managed to solve any given problem of development. If I am able to apply these learning tools and meet my objectives that I have set for myself, I think that I will be able to call my taking this class a success. At the same time, as I progress through the classes I think that certain objectives may be

Anger, Hatred, Powerless, and Connection Term Paper

Anger, Hatred, Powerless, and Connection - Term Paper Example In this paper, I address the conflict between the view that anger is different from hatred and that anger and hatred are one and the same thing. In the following, I assume that there is temporal hatred that comes when one acts emotionally out of anger, which may not be distinguished from hatred that may cause a conscious anger and is remarkably different from anger itself. If Buber were to personalize the two terms and fit them into his dual system, he would group the temporal hatred and anger in I-Thou set where the entities consist of, specific isolated qualities, but engages in the same realm of unconsciousness. The permanent-conscious hatred and anger would be classified as I-It where they are different and exist independently. Anger can lead to temporal hatred or permanent hatred. This relationship can be clearly explained by the following scenario. Mike is mired on the highway by a traffic jam. He is supposed to attend a staff meeting, but the traffic is moving at a snailâ€⠄¢s pace. While on the traffic jam, another car keeps intercepting and flouting traffic rules. At some point, the car attempt to fix itself ahead of Mike and it slightly collides with his car. At this point, Mike rushes out with a metal bar, with eyes dilating, red and his heart thumping, and smashes the windscreen of the offending car. At this particular point, Mike is angry! Mike was angered, and he developed a temporal hatred for the offending driver and the driver’s action. Suppose on arrival, Mike find that his former manager, whom he hated for being un-understanding is chairing the meeting, and he decides to punish Mike by suspending him. On trying to explain his case, the chair interrupts and claims that Mike has always been late and that his actions are deliberate. Mike is angry again, and this time round he may not take action. Thich Nhat Hanh warns that, in our daily lives, we must practice mindfulness so as to identify anger, analyze the effect of anger that comes from within us than that, which comes from without. This is because the primary cause of anger is the anger within us or the hatred within us, like the case of Mike and his manager. Thich quotes the Buddha who asked â€Å"How can anger arise in one who has no anger?† Anger, being an emotional state of soul, could not arise if we had no seeds of anger in our store of consciousness because events and words act as catalysts of what is already within us. This is the reason as to why, two people can experience the same event or hear the same words, but one gets damn angry and the other one not. Therefore, in Mike’s scenario, one person can be said to have self awareness of his state of emotion unlike the other. Since anger can lead to either noble actions or disgraceful ones, it means that we have discretion to choose what to do. Gould quotes Hanna and Brown (2004) lengthily regarding this self awareness thus; Self-awareness entails individuals’ ability to label thei r emotions, whether pleasant or unpleasant, and to accept them as part of being human. Self-esteem involves an acceptance of emotions as pertinent information about the self and an ability to act responsibly on those feelings. When individuals are not able to tolerate their fears or anxieties, they develop controlling, or addictive behavior intended to numb unpleasant emotional states. (p. 81-82) Thich analyzes that one should master his or her own anger, so as to help others manage theirs. This self mastery emanates

Group Decision Making Essay Example for Free

Group Decision Making Essay Abstract Group decision making is imperative for deciding what action a group should take. This paper aims to define the process of group decision making and examine the discipline, theory, paradigm, and methodology that dominate approaches to group decision-making research. Furthermore, it provides an outline of the research’s perceptual process and endeavors to address an appropriate alternative approach to this research problem, and an evaluation of qualitative and quantitative research designs for this area of research. These are discussed in connection with selected empirical data. Critical Review of Group Decision Making Research Group decision making is one of the most significant and methodological ways of overcoming and/or resolving certain conflicts with the aid of other individuals. It becomes a more controversial in deciding what action a group should take due to the varieties of systems, which are acknowledged in order to solve a particular conflict. Decision making in a certain group is frequently evaluated in a separate manner, as the issue with regard to the process and outcome is concerned. While such a process of group decision making refers to how every member of a group interacts with the others, the outcome is the result of preferred method or action that the entire group has taken. A number of masters from prestigious universities have been arguing with regard to the critical review of group decision-making research since the 19th century. One of the world-renown masters of that time was James Stoner who observed that group decisions are more speculative than the earlier exclusive decisions of the members of a particular group or organization (Stoner, 1961). During the period subsequent to the time when he released his masters’ thesis and scholarly articles concerning the critical review of group decision-making research, numerous researched studies with empirical bases have shown that such a perilous modification is omnipresent or ubiquitous occurrence. Moreover, there is the presence of judiciousness on certain group decisions than the members (Moscovici Zavalloni. 1969; Myers Lamm, 1976). However, the tendency of people to make decisions, which is extreme when they are in a group as opposed to a decision made alone or independently, will take place as a commencing disposition of an individual group members toward a specified way is increased subsequent to the given group decision. For instance, a group of pro-feminist women will be more powerfully pro-feminist subsequent to the given group decision (Myers. 1975). Therefore, on decisions that present to every individual group and/or member, a reasonable disposition in a specified way comes along with a group decision, which belongs to a more reasonable disposition in the same way. Critical Review on a Group Decision Some other conceptualization with regard to the tendency of people to make decisions, which is extreme when they are in a group as opposed to a decision made alone or independently, will be superfluous due the number of outstanding reviews and/or conceptualization until 1970s (Myers Lamm, 1976). Throughout this time, the arguments concerning such a conceptualization have become remarkable. Hence, numerous researchers contributed various ideologies and significant contributions to produce group decisions, which are more speculative than the earlier exclusive decisions of the members of a particular group or organization. In latter years, vehemence for group research with regard to disposition has begun to lessen; it has believed that a thorough retrospective view or survey will contribute to the reorientation of research in such a field. In addition to this view, reassessment will also incorporate the tendency of people to make decisions, which is extreme when they are in a group as opposed to a decision made alone or independently, with other gregarious or communal imaginary and cognitive phenomena. Thus, this research concludes by proposing a few significant matters of desegregation. Moreover, basic cognitive process will be involved in obtaining and storing more knowledge and insights upon demonstrating convincing disputation and communal distinction intervening the doctrine that all natural phenomena are explicable by material causes and mechanical principles within the bounds of group decision making. Study of this consequence shows that subsequent in time of taking part in a discussion group, every member tends to propose greater whereabouts; the demand for more perilous procedures of exploit than individuals who do not take part in any such discourse becomes inevitable. This incident has given birth to the perilous modification of group decision making. Moreover, the tendency of people to make decisions, which is extreme when they are in a group as opposed to a decision made alone or independently, is used in order to explicate and give light to the decision making of a panel or a group of people legally selected to hear a case and to decide what are the facts. Contemporary studies of world-renown scholars and savants show that subsequent in time to meditating into a single group, simulated panel of experts frequently determines retaliatory impairment prior to deliberation. Hence, the studies showed that when the favor of the panel of experts is given to an individual that bears insufficient facts and/or explications with regard to the extant issues, matters of argumentation might lead to a more compassionate outcome. While the panel of experts is influenced to ordain an efficacious or disastrous treatment, such contemporary discourse could yield severe and arduous circumstances to cope with. Progress in Analysis of Group Decision Making Brown’s (1965) innovative discourse of such a perilous modification, one of the vital vindications of selected changes, has been a communal juxtaposition. Based on the entire view of this conceptualization, people are regularly encouraged both to identify and to introduce themselves in a gregarious suitable illumination. To do this, every individual should be constantly preparing knowledge and insights with regard to how other groups of people introduce themselves, and changing his/her personal investiture. Some adaptations of social comparison theory shows that the number of people wishes to be understood as more advantageous than what other groups of people comprehend to be the standard movement. In one case that every individual distinguishes how most other people demonstrate and/or introduce themselves, he or she present him/herself in a reasonable illumination or awareness. Whenever all members of a colluding group involve in the same examination of such a methodological or systematic procedure, the outcome, therefore, is a mean modification in a way of valuable community. There is the presence of two fluctuations of the said temporal arrangement; one is that highlights the displacements of cognitive contents, which have multiple numbers of aspects, while the other one concerns the practice of keeping one jump ahead of a friend or competitor. Based on the studies of such a pluralistic ignorance, every individual or group of people introduces itself and/or its own positions as a settlement of differences in which each side makes concessions in the interval of two different proclivities—the petition to be bound by mutual interests, loyalties, or affections to an individual’s own conception of absolute perfection. In addition to this view, the desire not to be aberrant from the notion of the inner direction of a certain group is also acknowledged. Thus, prior to group discussion review or argument, every member of a particular group trivializes the standards of the group ab initio. Evaluation from the primary valuations of their personal standards becomes distant to some extent or degree. Throughout the argumentations, which are unfolded by the entire group, every individual or member of the group is acknowledged nigh to the right standards; hence, an instance of divergence or disagreement by the common action of how good a group member is and how he or she likes to be ostensible. On delving into the second set of options, a group member directly changes to a more idealistic thought or matter of argumentations. As such, the strategic method of group decision making with most group members is acknowledged. Therefore, the theory concerning pluralistic ignorance is that it prevails for the mere reason of precise exchange of information with regard to the true beliefs of most members of the group in spite of the fact that it might be due to the preconception, which has a basis in or reducible to empirical factual knowledge (Jones Nisbett, 1972). Other evaluators made a thorough explication concerning the possible outcomes of procedures in relation to the social comparison. These evaluations have become a more controversial along the issue concerning such matters of argument in which the group of people are encouraged by an aspiration to be unique from the other groups of people in a more precious and significant way or direction of feelings and/or thoughts (Fromkin, 1970). Moreover, these people are also encouraged to introduce themselves in a more advantageous way than the other groups of people. Briefly, such a group of people desires to be unique and become better than other groups of people. As an analogy, Brown expresses his own feelings by acknowledging the fact that when creating pre-valuations in a certain aspect, every individual member of the group gives him/herself a valuation, which is moderately advantageous than the valuation that he or she takes for granted—the norm or standards the mean group member will share. For a better comprehension with regard to this conceptualization, when a member directly or indirectly deducts the precise standards, he or she then develops his or her personal valuations; hence, making the general options with regard to the perilous modification becomes inevitable to acknowledge. Inasmuch as the technical aspects of making the perilous modification in cognitive contents, which have multiple aspects, the technical aspects concerning a current or fashionable trend is a settlement of differences in which each side makes concessions by the common action of self-enhancement and self-abasement. Indeed, however, it may be quite arduous to acknowledge these two technical aspects theoretically. Nevertheless, there are respective imbrications on the pluralistic ignorance and current or fashionable trends. To support such an argument, the general reference for social comparison comes from presentations that coherent knowledge and insights with regard to the standards of other group members is able to make conformation bias. It takes place when combined or neutral vestige is used to reinforce an already made and intelligibly one-sided point of view. Consequently, every member of the group on both sides may therefore make an action or any movement farther apart, when he or she is presented with the same combined vestige. Such e strategic effect is called ‘mere exposure’ effects in which numerous researched studies have tried creating this terminology for further explication of the denotations of the perilous modification within the group decision making. Processing the Information that Affects the Group Decision Making A number of scholarly studies with regard to the group decision making from different pats of the world have been published; now, it remains one of the global contemporary issues. The original perilous modification research of Stoner (1961) has been globally recognized upon the use of certain outlines of the summary with a dramatic or literary work—the scenario, which shows the value of perils that a group member thinks what action he or she should take. For a better comprehension, it is explained with the best example, which Stoner used. He shows such a perilous modification through playing with a chess—the moves, careers shifts, professional shifts etc. In addition, other studies concern the probability of such a perilous modification. It is showed through the frequent exposure of conditions in which it is more likely to be substantial than any moderate exposure of such conditions; mixed with non-significant. Some studies argue that a certain member’s option or a standard on the matter of argument is methodological function of numerous pro and con debates. It is acknowledged as an individual calls back the memory when hypothesizing his or her personal thought or standards. Therefore, in forming an opinion or estimation of the guilt or innocence of an accused person after careful consideration, a body of citizens sworn to give a true verdict according to the evidence presented in a court of law comes to pre-deliberation decisions in accordance with the respective number and strength of the pro-guilt and pro-innocence statements. Consequently, a formal discourse on a topic or an exposition becomes the cause of an individual’s modification of his or her thought with regard to the running skepticism in the court. During the period subsequent to the time when the conceptualization of the power to induce the taking of a course of action or the embracing of a point of view by means of argument or entreaty is acknowledged, a number of studies distinguish the characteristics of statements, which lead them into being convincing. Moreover, some studies express the denotations of perilous modification. They show this through presenting deputations on the statements within the group members. For a better comprehension concerning this ideology, a specified group may or may not change the way, which has given to it. While every member thinks of producing a good outcome, the arguments take place from the other members of the group. Thus, the function of originality is certainly and specifically determined. However, if such statements or arguments are given from the fact that the individual member is already acquainted with such matter of argumentations, he or she then cannot modify or change his or her position or standards of thinking or sharing his or her thoughts with the other members of the group of choice (Kaplan, 1997). Evaluating Qualitative and Quantitative Research Designs As such, if new convincing arguments are given, but opposing the way that has been pre-approved by the group member, their standards will be modified reversely. Hence, a body of citizens sworn to give a true verdict according to the evidence presented in a court of law who pre-approved one who is justly chargeable with or responsible for a usually grave breach of conduct or a crime will come to regard a more guilty opinion or treat him or her with favor. This occurrence takes place only if he or she is liable to the new statements, which give favor to the fact of having committed a breach of conduct especially violating law and involving a penal. The condition of being peculiar to a particular individual or group, as the issue with regard to the process by which other studies or scholarly researched articles produce, accommodates two general empirical bases. One is that concerns the given correct information. To understand better, such studies or scholarly articles anticipate the methodological system and extent of selecting the thought to be unfolded on the matters of argumentation whether they are breaking up into opposing factions or grouping, or causing to become partially or wholly unbroken up to opposing factions. In addition to this statement or argument with regard to the critical review of group decision making, the number of studies make it easier to bring out the conceptual coordination of mental processes into a normal effective personality or with the individual’s environment, or the operation of finding a function whose differential is known and/or solving a different equation. In view of that fact, the fundamental technical aspect is the same for statements, which have been processed in a more advanced and secure system, or in a mutual or reciprocal action or influence with the other people or group members. Therefore, to support the entire conceptualization of this view, the vestige for the proposition that convincing statements alone may yield choice modification and a position of polarization, which has been assumed for a specific purpose—boldly supported by advanced explications of polarization (Pruitt, 197la. 1971b). Conclusion I have learned substantially from the said research and conceptualization of contemporary argumentations with regard to the critical review of group decision making and it impelled me to seek various means to learn the more advanced and methodological process of critical thinking and evaluation on the group decision-making. First, I have learned to perceive more contemplatively. This means, prior to making decisions or establishing beliefs, a group member must be aware that he or she has personal biases about certain things and he or she should not let this get in the way of arriving at an accurate perception and wise decision. Second, I have learned that by being more involved and by listening to and observing people a particular member of the group, who joins the arguments while discussing the best things to gain favorable outcomes, would be able to gain a broader perspective, if not a holistic view, of people and circumstances as a whole. This means that he or she should not only be satisfied with what he or she sees or wants to see but endeavor to look further and probe deeper into what is actually happening that he or she could not directly sense. Moreover, he or she should also verify his or her perceptions and the conclusions he or she has reached through critical thinking by communicating and learning more about the entities involved. These helpful hints have caused substantial improvement in my critical thinking process relative not only to the office works but to all the other daily activities as well. They have led me to perceive accurately, think critically and gain greater understanding of people and contemporary events. References Brown. R. (1965). Social psychology. New York: Free Press.

Dhaping human behaviour Essay Example for Free

Dhaping human behaviour Essay Socialisation is the lifelong process by which human behaviour is shaped through experience in social institutions (e.g. family, which is a crucial factor in primary socialisation). Through socialization, individuals learn the values, norms (formal and informal rules), and beliefs of a given society.  In considering the nature of the self, it is necessary to include a still more fundamental social scientific issue the extent to which human beings are being formed by biological inheritance (i.e. genetic determinism), or through socialisation (i. e. cultural determinism); the issue called nature-nurture debate. Another way to put this is the difference between instinct and learned behaviour, where instinct is inherited, and learned behaviour acquired through socialisation. Sociologists does not really consider instinctive behaviour; therefore, most sociologists would only accept there are inborn needs of food, shelter and sex. Other than these three, sociologists prefer the fact that human behaviour is shaped by social experience rather than that it is biologically given.  However, although the direction of sociology is towards social explanation, there is no contradiction between social and biological explanations of behaviour. It is just a matter of empirical research by biologists, sociologists, social biologists and by other relevant subject specialists to find explanations of human behaviour. According to sociologist Charles Cooley, there are two types of socialisation: primary and secondary. Those factors that are involved in primary socialisation are usually small, involve face-to-face interaction and communication and allow the individual to express the whole self, both feelings and intellect. Usually, those factors are the family, peer groups, of close friends and closely-knit groups of neighbours. Within these groups, through personal experience, the individual learns primary values such as love, loyalty, justice, sharing, and etc. Freud claimed that the first few years of a persons life those usually spent amongst primary groups are the most important in forming the structure of the persons character. In contrast, secondary groups are usually large, more impersonal and formally organised, and exist for specific purposes. In the secondary stage, the individual learns by himself or herself more values and norms which are to be applied for the individual to fit in. This includes learning how to organise and conduct oneself in formal contexts (backgrounds) and how to behave towards people who have different degrees of status and authority. One of the crucial agents of secondary socialisation is school. Trade unions and professional associations, also secondary socialisation agents, can affect an individuals behaviour when an individual agrees to conform to the beliefs, aims and regulations of the organisation. Therefore, indirectly, the individual accepts a socialising influence on his or her conduct. In both primary and secondary groups, the mass media (e.g. radio, television, the cinema) also plays a vital part in socialising individuals. For example during primary socialisation, by watching certain cartoons, a child (although indirectly) can already be socialised of his or her gender roles, such as patriarchal ideology (e.g. where the cartoon might portray the girl as the weaker one, always being bullied and being the helpless, damsel in distress; while the boy will then be the hero). Later, during secondary socialisation, magazines (a form of mass media) can also reinforce gender roles such as saying that girls must learn to cook so that they could cook for their husbands later in marriage. One way of studying the role of society in shaping human behaviour is to examine the development of individuals who were either completely or nearly excluded from any social interaction for a period of their lives. This includes cases of those who spent most of their childhood isolated from others in the wild (such as the Wild boy of Aveyron and the two girls, Wolf children of Bengal) and those who were cut off from others through confinement (imprisonment), also during childhood (such as the cases of Anna and Isabelle). The case of the wolf children revealed that their behaviour was very similar to the wolves that had apparently raised them. They preferred raw meat, moved on all fours and lacked any form of speech. There is a more recent case described by ODonnell where a 14 year old boy found in the Syrian desert had exceptional speed and had adopted some of the behavioural characteristics of the gazelles he was found with.

Intake Manifold of the Internal Combustion Engine

Intake Manifold of the Internal Combustion Engine Abstract Intake manifold of the Internal Combustion engine is a subsystem which supplies fresh air-fuel mixture into the engine cylinders where combustion of fuel takes place. For Efficient Combustion of the charge, the walls of the intake manifold must be smooth/polished to reduce any sidewall resistance. The traditional materials used for intake manifolds were cast iron and Aluminum. In order to reduce manufacturing costs and improve thermal efficiency, new composites are proposed. Inside the cylinder, the energy generated from combustion of fuel is converted into pressure and heat during the power stroke. The pressure and heat increase rapidly within a short span of time. The piston converts this energy into mechanical work. In place of the traditional aluminum alloys, Al-SiC material is proposed which have superior properties. Exhaust manifold is responsible to remove the depleted charge and create space for the incoming charge. Materials used in exhaust systems of engines must have High Temperature Service capability, superior fatigue strength, and good fracture toughness, be easily machinable and economic considering the overall cost of the automobile. Mo-Nb added ferritic stainless steel is a new material that is gaining reputation for its high formability and high heat-resistance. Introduction Internal Combustion Engine is a complex machine that does mechanical work when the air-fuel mixture is ignited under high pressure. The Air-Fuel mixture is sent into the Combustion chamber through the intake manifold which is responsible to maintain proper supply of ignition charge into the engine always. The structure of the intake manifold must be such that it has low sidewall friction and maintains lower temperature so that the charge doesnt pre-ignite. The piston is the component that creates the necessary horsepower inside the engine. It must be light weight and must have good thermal properties. The exhaust manifold deals with the hot gases coming out the combustion chamber. It must be able to maintain flow of exhaust gases without any hindrance. Failure in the exhaust system can cause loss of back pressure which can significantly affect engine performance. Intake Manifold 1. Introduction Intake manifold in the car engine is the system which supplies fresh air into the engine cylinders where combustion of fuel happens. The Intake Manifolds in Internal Combustion engines are one of the most engineered components. High precision is needed to efficiently send right amount of cold, high pressure air in equal quantities and at the same pressure. Earlier generations of cars had intake manifolds made from cast iron, which were heavy. In high volume production cars, the use of injection molded composite intake manifolds has been increasing rapidly. [1] AE 587 Final Research Report Winter 2017 Material Selection for Intake Manifold, Piston Exhaust Manifold Tarun Krishna Prabhakar, Rohit Vedachalam, Pranav Radhakrishna Figure 1: Intake manifold made from Nylon 6,6 [23] An intake manifold is an integrated unit of any engine, made up of a series of tubes/ducts which distribute fuel-air mixture to each cylinder. For V-shaped engine blocks, intake manifold is integrated between the two cylinder rows whereas inline engines have manifolds to side of cylinder head. Intake manifolds also perform as mounting points for Fuel injectors/carburetors, thermostats, throttle assembly depending on the manufacturers engineering designs. Because of the location and functions, intake manifold assemblies experience constant stress from the engine vacuum pressure as direct heat from cylinder combustion gases, and the cylinder head. Figure 2: Evolution of Intake Manifold over the years[24] Until 1990s, most automotive intake manifold assemblies were made from Cast Iron because of lower cost, or from Aluminum which has lighter weight is required for performance/efficiency. Intake manifolds made from plastic began to gain popularity during 1990s because they offered lower weight and cost combined. They were Factory installed when auto-manufacturers figured out how to manufacture them so that they are durable enough to survive high stresses. [2] Aluminum is robust metal, but it has few drawbacks. Namely, 1.) It is cheaper to manufacture intake manifolds with advanced composite molding plants than cast out of Aluminum.2.) Composites have superior heat retention and heat resistance compared to Aluminum and other metals. This means that Phenolic spacers used in previous aluminum intakes are no longer required.3.) Smoother airflow with lower sidewall resistance compared to Aluminum casting, which requires high level of polishing to achieve same flow of air. However, there are few disadvantages:1.) Composites are more flexible, more prone to damage.2.) Composites or plastics are cheap and deemed unattractive. Dissimilar materials such as plastic, aluminum, and iron all have different expansion and contraction rates as they change temperature, so gaskets that provide a seal between an intake manifold and a metal cylinder head must be flexible and durable enough to withstand serious pulling and twisting forces. Early ones were not, and leaks resulted along with warpage under intense heat that eventually led to cracks. Therefore, composites offer several advantages. they saves money, reduces weight, ease of assembly, better insulation, improved airflow, excellent strength to weight ratio, and is recyclable. 1.2. Material Comparison [3] Properties comparison for PA6 (dry/humid), AL 6082 T6 and 316 stainless respectively: Yield strength (MPa): 80/45, 260, 290Elongation at failure (%): 70/200, 8, 50Ultimate Tensile Strength (MPa): 85/48, 310, 579Charpy impact toughness (J/square cm): 0.7/8, 10.6, 134 1.3. Existing Material and Process Material: 319F Aluminum Cast Component: Aluminum Intake Manifold Process: Semi Permanent Mold Casting For a Manifold of an opposed cylinder layout, Intake Manifold alone weighs 4.5 kgs and with the Phenolic spacers it weighs 8.2 kgs. The casting is done by Gravity Tilt Pour process, which can achieve minute thickness upto 3mm. [4] 319F Aluminum is an alloy comprised of 6% Silicon and 3.5% Copper and Iron ( Table 1: Properties of 319F Aluminum [26] For Aluminum, permanent mold process can be utilized to have sand cores to create complex castings. Die castings cannot use cores made of sand. If cores are used in the permanent molding process, it is sometimes as called semi-permanent molding as the mold is permanent but new cores must be made for the next batch. Permanent mold casting is one of the low-cost method of producing any Aluminum casting. Generally, Permanent mold castings are better than simple sand castings when the factors like ultimate and yield strength are compared. They have better elongation, which is good for ductility. Even appearance of Aluminum in permanent mold castings is better than appearance of castings made from sand casting process, which translates that lesser machining and polishing is required after casting. The cast is made using a single core. The passageway core is made by coldbox process for making cores, main body core is a blown core type and the external core is made using semi-permanent mold process with three solid cores and one internal passageway core. Below is a picture of the finished Aluminum Air Intake Figure 3: Aluminum Air Intake [25] 1.4. Proposed Material and Manufacturing Process Material: A-6135 HN PPA(PolyPhthalAmide) Cast Component: Composite Intake Manifold Process: Thermoforming Nowadays, Original Equipment Manufacturers (OEMs) use PA6 or PA66 is used for intake manifolds. In the performance aftermarket, there is possible use of engine performance enhancers like nitrous oxide or turbocharging or supercharging, so perhaps a higher-grade composite would be more appropriate. A-6135 HN polyphthalamide (PPA) is a 35% glass reinforced resin which is heat stabilized. Main properties of this resin are high strength, high stiffness, and high heat resistance over a broad temperature range. It also exhibits low moisture absorption, good against chemical action and electrical properties. AMODEL A-6135 HSL polyphthalamide acts as a solution to both performance and processing requirements. At elevated temperature and humid conditions, the tensile strength of A-6135 resin is 20% stronger than nylon 6, and much stronger than nylon 66. The flexural modulus of this compound is a minimum of 20% greater than stiffness of nylon 6 or 66. [6] Figure 4: Tensile strength and Flexural strength comparison between composites [26] For current generation vehicles, plastic intake manifolds are made using the injection molding process. Thermoforming is explored as an alternative to injection molding for making intake manifold shells, which can then be joined by one of the welding techniques used for thermoplastic materials. There is now an increasing trend in integrating several components, such as fuel injection, in engine air/fuel modules. The assembly of these components is achieved via either snap fits or threaded fasteners. Increased integration is generally associated with increasing shape complexity. The advantages of shell design in the integration approach are lower number of fasteners required. Figure 5: Thermoformed Shell type vs Lost Core Design [27] 1.5. Thermoforming Figure 6: Shows thermoforming principle [28] It is a manufacturing process in which a plastic sheet is heated to a temperature where it melts and is flowable, to make molding into any predefined shape/pattern and the flash is trimmed to get the final product. Thinner gauges and other materials too are heated in an oven to high temperature which allows the film to stretch or mold and cooled to a final shape. In Thermoforming, Vacuum forming is the simplest method. [8] Press forming is another type of thermoforming process which is used in work like the sheet metal stamping. Matching metal die set is used here. Preheated plastic sheet is placed on the bottom die and the top die is lowered to close the mold. The hot Plastic sheet gets stretched as the mold closes and then drawn into the shape of die. The sheet is allowed to cool down to take its final shape. For Complex geometries, the component is divided into 2-3 layers where the molded parts can be assembled and held together by means of fasteners or adhesives. Figure 7: Dies used for Manufacturing Shell type Molding of Intake manifolds [29] Figure 8: Finished Air intake manifold made of PPA [30] Figure 9: Comparison of PPA and Aluminum intake manifolds [31] Automotive Pistons 2.1. Introduction In the cylinder of an engine, the energy of the fuel is converted into pressure and heat during the power stroke. The pressure and heat values increase rapidly within a short interval of time. The piston converts the same into mechanical work [9]. The pistons structure consists of piston crown, ring belt, skirt and piston boss as shown in Figure1.1. During the power stroke, the forces resulting from the combustion of fuel-air mixture are transferred from the piston crown to piston boss, piston pin, connecting rod and finally to the crankshaft [9]. Figure 10: Engine piston [9]. 2.2. Forces on piston The forces acting on the piston are, oscillating inertia forces of the piston and the connecting rod (FK), piston force in the direction of the connecting rod (FST) and lateral force or normal force (FS). During the working cycle, the direction of lateral force changes several times, which oscillates the piston from one end of the cylinder bore to the other, due to the existing piston clearance [9]. Figure 11: Forces on the piston [9]. 2.3. Temperatures in piston Temperature is an important parameter for the operational safety and service life of a piston. The exhaust gas temperatures, even though is present only for a short period, can exceed more than 2,200ÂÂ °C. In gasoline engines, the exhaust gas temperatures range between 800ÂÂ °C to 1,050ÂÂ °C, and 600ÂÂ °C to 850ÂÂ °C for diesel engines [9]. Figure 12:ÂÂ   Temperature distribution in a gasoline engine piston [9]. Figure 13:ÂÂ   Temperature distribution in a diesel engine piston [9]. 2.4. Failures of internal combustion engine pistons Failure of piston is one of the prime reasons for engine breakdown. The failure may occur at different mileage and operating conditions which are usually caused by material defects, engineering, and operational errors. Common causes of piston failures include: 1) insufficient cooling and lubrication of the piston, 2) thermal fatigue, 3) incorrect combustion process, 4) mechanical damage [10]. Figure 14 shows fusion of piston head and ring area in a gasoline engine. It is caused due to a phenomenon called hot bulb ignition occurring on the pistons, primarily on their heads, and in the larger flame extinguishing areas. The hot-bulb ignition occurs in the areas of combustion chamber, which have temperatures higher than the autoignition temperature of the air-fuel mixture. This causes the temperature of the piston head rapidly increase, soften, melt and fuse with the ring [10]. Fig. 14: Fusion of the piston head and the ring area [10]. Figure 15 illustrates a piston skirt seizure. From the figure, it is evident that piston skirt has completely seized. The dark coloring on the surface is due to rough and heavily over- ground abrasion spots. Causes for the failure include: 1) Overheating of the combustion chamber, 2) Poor lubrication, 3) Incorrect combustion process [10]. Fig. 15: Piston skirt seizure [10] Figure 15 illustrates propagation of fatigue crack of the piston pin along the semicircle. This fracture divides the piston head into two parts -as shown in Fig. 5. These are cracks due to excessive loads on the piston pin. The crack grows rapidly with poor lubrication and will ultimately result in the failure of the piston. Causes for the failure include: 1) Incorrect combustion process, mainly by delayed ignition, 2) incorrect starting of the cold engine, 3) hydraulic lock caused by water present in the fuel [10]. Fig: 16:ÂÂ   Crack in piston head and skirt [10]. 2.5. Materials Pistons are usually made of Aluminum and Aluminum alloys of eutectic, and partly hypereutectic composition which have high wear resistance. The most commonly used eutectic alloy is M124. Alloys such as M138 and M244 were used in two-stroke engine pistons, while M126 alloy was preferred in gasoline engines. The other recently developed alloys include M142, M145, and M174+, common composition of these alloys include elements of copper and nickel which provides high strength at elevated temperatures and thermal stability. The eutectic alloy M142 and M145 are used in gasoline engines, and the alloy M174+ in diesel engines. Aluminum Metal matrix composites are a new class of materials used in pistons which have superior properties than Aluminum alloys. These composites consist of Aluminum as metal matrix and SiC, Al2O3, TiC, TiB2, Graphite and certain other ceramics as reinforcements [9].

Current manufacturing process 2.6.1. Permanent Mold Aluminum Pistons Permanent mold is one of the oldest and common process used for manufacturing pistons. It consists of steel mold with single or multi-piece inner cores to create various intricate features of the piston.ÂÂ   This process is a relatively cheap for high volume for a justifiable tooling cost. Parts can be made of various alloys with improved strength at elevated temperatures. High tooling cost and porosity are the main disadvantages of permanent mold process [11]. 2.6.2. Forged Aluminum Pistons Pistons are forged for obtaining high performance, large bore, and increased strength.ÂÂ   Heated solid cylindrical aluminum blank is pressed into a die to create piston. The process yields low defective rate, increased ductility, and fracture toughness [11]. 2.6.3. Billet machined pistons Billet machined pistons are machined from the same wrought aluminum materials which are used in piston forging.ÂÂ   Billet machined pistons have high surface finish and has no tooling cost. The main disadvantage of this process is high cost [11]. 2.7. Improved materials: Aluminum-Graphite composites were primarily used for automotive antifriction applications. Low cost, good machinability, improved damping capacity are the main advantages of this composite. Aluminum-Graphite composites can be fabricated from various casting processes such as permanent mold casting, squeeze casting, centrifugal casting, and pressure die casting. Pistons made of Aluminum-Graphite composites exhibit properties like, low wear, minimal frictional loss, and elimination of seizure from poor lubrication [12]. Aluminum-Silicon Carbide composites have excellent specific strength, specific modulus and wear resistance. The amount of SiC determines the effect of coefficient of thermal expansion, higher the SiC content, lower the coefficient of thermal expansion. Conventional casting processes such as sand casting, permanent mold casting, investment casting and squeeze casting are used in manufacturing these composites [12]. 2.8. Analysis of aluminum and Aluminum-Silicon-Carbide pistons Firstly, a CAD model of a piston is built in CATIA V6, and is structurally and thermally analyzed using ANSYS 14.0 software [13].

insane narrator :: essays research papers

The Insane Narrator Edgar Allan Poe was born on January 19, 1809 in Boston Massachusetts. His parents David Poe Jr. and Elizabeth Arnold Hopkins, both died when Edgar was very young. Calvin Thomas published Poe’s first book, Tamerlane and other Poems in Boston in 1827. His first real job was the editor of Thomas W. White’s Southern Literary Messenger where he worked for nearly a year. In 1836, he was married to his 13-year-old cousin. He wrote many short stories including the Tell-Tale Heart in 1843, which is about a murderer who is subconsciously haunted into confessing what he just did. He died on October 7, 1849 in Baltimore. The narrator is insane because of his unnatural preoccupation with the eye, his distorted logic, and the hearing of voices and sounds, which reveal the madness. For some strange reason, the narrator was obsessed with the old man’s eye. He wasn’t even certain on how it started, but to him, it was an eye of a vulture. The old man was going to be murdered because of his pale blue eye. Infact, for seven straight nights at midnight the eye was closed. It wasn’t until finally on the eighth night when the narrator’s thumb slipped on the tin fastening, which woke up the old man. He grew furious when he did see the eye and new inside that he must murder this old man because of his eye. It is hard to imagine why a person’s eye would bother another person enough to kill, but some people are truly insane. His logic was distorted, so to him, the murder of the old man was the only thing that could soothe his pain. He then made the decision to only kill him when he saw his eye. This took him eight days, though I’m sure he would have done it the first night if he had the chance. While he was killing the old man, he had a smile on his face. The murder of the old man was justified.One might think that the narrator needed to murder something for a reason. The reason for killing the old man was absurd, but it worked for him. He also heard voices that would haunt him day and night. Those voices told him the eye was evil, and that he was doing the right thing. He would also hear a groan of terror many nights at midnight.

The History of Alcatraz Essay -- American America History

The History of Alcatraz INTRODUCTION Alcatraz is an island that is 22 acres and according to geologists it is a drowned mountain peak and is made up of mostly rock and dirt. The island itself is a part of a cluster of islands that are in the San Francisco Bay area. The island's name came from a Spanish explorer, Lt. Juan Manual de Ayala, and the ship's pilot, Jose de Canizarer, on August 12, 1775. He called it La Isla de los Alcatraces, in English is Island of the Pelicans. Alcatraz is just the singular form of Alcatraces. The owners of the island have changed three times in its history. First Spain owned it until 1822, then Mexico won its independence and claimed ownership and finally in 1846 Mexico/California went to war and it then became the property of the United States. On the day of November 6, 1850, President Millard Filmore agreed to make Alcatraz official government property. It was to be turned into a fortification to protect the city from hostile vessels and the reason for putting it there was because it was on an island in the middle of the bay- very strategic. There would be two batteries on both ends of the island along with a two-story brick wall that would enclose all of it. Inside there would be soldiers' barracks, guard houses, powder magazines, and warehouses that would be the backbone of Alcatraz. The official day of opening of Alcatraz was in December of 1859 and it had two purposes, one of fortification and another of a prison. The prison was there for military members that committed various crimes. The prison had about 15 - 50 prisoners there, but they were not all military, some were local citizens and politicians who committed crimes of varying degrees. The idea of having a prison on an is... ...aying that any land that was in surplus would be theirs. Then the City of San Francisco wanted the island so they could destroy what was one their and start commercial development. However, that did not happen because there were to many protestors about saving Alcatraz. Then there was of period of 4 or 5 years of many proposals about what to do but in 1972 it was decided to turn it into the Golden Gate National Recreation Area. Alcatraz was now open to the public and today you can go down and get on a tour to see where some of the U.S. most famous criminals stayed. BIBLIOGRAPHY "Alcatraz."

Good or Evil :: essays research papers

Good or Evil? The topic of this journal, is one that has caused much debate for a long time. Are we inherently good or evil at birth, or are we nurtured to be so? Many people believe that we have a natural tendency to be evil. Others think we are born good. To make thing a little bit clearer, I will give my definitions of what â€Å"good† and â€Å"evil† mean in this journal. â€Å"Good† as explained later, means â€Å"obeys rules and ethics of society over several centuries†. â€Å"Evil† means, â€Å"deliberate, or ignorant actions against rules of society†. Personally, I think that we are born impartial to either side, and it is our experiences, and the things that are impressed on us as we grow up. If a person were to grow up with no influences, then they would be pulled to what we see as evil, such as smashing a little RC car because it almost tripped them, which, if we didn’t know it was wrong, we would probably do so also. Another example toward my theory is that if you made two clones, and sent them down two paths, one to a rich family, and the other to a lower class family, at birth these two people are the same, and at death, they are entirely different. They could have been exactly the same, however, because of their upbringing, and experiences, they are entirely different people. An example not unlike my previous one would be my sister and I. We are twins, yet our interests are different, because we have perceived events differently, and we have had different influences in our lives. Even though she is a girl, and I am boy, I still believe if we had had the same experiences each other had, we would balance out to have relatively the same personality. Some people add to the theory I believe in. They say that what I say is true, however, they think that certain things are wired into the brain during creation, so two clones could be the same, (They both are genetically programmed to love a type of animal) but one likes dogs, and the other flying squirrels.

Good Will Hunting Identity Essay Essay

The identity theorist’s Erik Erikson and James Marcia were crucial contributors to the psychological interpretation of a person’s personality and social development. Erik Erikson is most famously known for his theories on the adolescent search for identity and his ideas regarding a person’s self-discovery. James Marcia expanded further on Erikson’s concepts through his proposal of the four identity statuses, which include moratorium, foreclosure, diffusion, and achievement, as well as the four human crises’. As psychology is becoming more and more developed in our modern society, it has become more socially acceptable to criticize or expose the issues psychology entails, particularly human identity, which often times can be the most controversial topic. In the blockbuster film, Good Will Hunting, the main character Will has natural genius capabilities but struggles to understand his place in the world due to a dramatic past and his tough exterior as an orphan from South Boston. Although it is arguable that Will appreciated his talent but preferred to live his life as it was before recognition, Will Hunting depicted the theories of identity through his relationship with Skylar and his guidance from Sean. Even though Will enjoyed his life of literature and education behind closed doors, it was indeterminable whether Will was content with his life or eager to leave his comfort zone in Southie to challenge his intellect at the beginning of the film. For example, while working as a janitor at MIT Will solves a problem that the current students at the institute had yet to conquer, however Will would not admit to the professors that he had solved it. This shows that Will lacks aspects of self-realization because once the professors realize he is the genius, Will mocks the therapy sessions and mathematical lessons that the professors organized in order to help him reach his full potential. In addition to that, Will’s best friends depict the epitome of â€Å"city kids† who balance blue collar jobs with nighttime bar reunions and it is evident that because this is the only life Will has ever known, he is hesitant to lead the life he is stereotypically supposed to. It takes the guidance from Will’s best friend Chuck, to finally persuade Will to take advantage of his gift, not for himself, but for his friends and  every other kid with the same lack of opportunities who would give anything for Will’s intelligence. At first Will was uncomfortable with realizing his intelligence but eventually he learned he needed to take advantage of his skills. Sean’s influence on Will proved that Will experienced the process of identity discovery proposed by James Marcia because of Sean’s ability to help Will out of his identity crisis. According to Marcia a person experiences four identity crises including future work, moral standards, religion, and political view. During the movie, Sean helps Will by guiding him past the future work crisis through therapy sessions and Sean’s real life experience recollections. In addition, Sean enables Will to overcome his moral standard crisis particularly regarding women. Throughout the movie Sean is able to overcome Will’s sarcastic defense mechanisms and on their last session when each man reveals they were abused as children, Sean sees the true person that Will is and realizes he has properly prepared him for a future job in the real world. Sean encourages Will’s relationship with Harvard Student Skylar because he wants Will to recognize his ability to have an emot ional relationship with a woman without pushing them away, which ultimately proved his change in moral standard. When Will meets Skylar she is unlike any girl he has ever known, and as their relationship grows serious, Will’s fear of commitment supports his struggle with his identity status. After Will receives Skylar’s number he is not contemplating commitment nor immediately calls her. Psychologically he is at the stage of moratorium where he delays decisions about Skylar before going out with her again as well as not disregarding his options with other woman, as he tells his psychologist Sean that he has slept with many woman. However, when Will takes Skylar to the dog track he proves his committal to her as his girlfriend, which supports the proceeding identity status of foreclosure. Next, after their relationship grows serious, Skylar asks Will to come to California with her as she attends Stanford yet Will refuses her offer and feels the need to distance himself from her. The issue escalates further when Skylar tries to comfort Will about his tragic past, which infuriates Will even further. After their break-up Will searches for the  meaning of life with help from his best friend’s who purchase him a car to help him commute to a new job which would enable him to break from his â€Å"tough city guy† image. Between the time of breakup, job interviews, and guidance from Chuck Will discovers his potential and strives to successfully use his talent through the identity status of diffusion. Finally Will reaches the achievement identity status as he leaves Boston to reunite with Skylar in California, which proves to be the greatest decision of his life. Overall, Will did undergo the four identity statuses and experience the crises that James Marcia and Erik Erikson proposed in their theories of self-discovery. Will’s relationship with Skylar particularly proves that Will underwent the four identity statuses of moratorium, foreclosure, diffusion, and achievement because of his refusal to get emotionally attached to her at first, and then by the conclusion of the movie, ready to commit his life to her. Also, through the guidance of Sean Will overcame the identity crises of future work and moral standards. In the end, although it appeared as if Will could never behind his reputation of a South Boston rebel, through his relationships with Skylar and Sean Will was prepared to reach his full potential.

â€Å"Anything?† Rachel asked.The pilot let the arm make several complete rotations. He adjusted some controls and watched. It was click all clear.Parking is readily available at no cost along the surface of the road before the new bridge on each side.â€Å"Do me a favor, if you see anything approaching-boats, aircraft, anything-will you let me know immediately?†Ã¢â‚¬Å"Sure thing. Is much everything okay?†Ã¢â‚¬Å"Yeah. Id just like to know if were having company.†The pilot shrugged.If powerful tools arent accessible the PI can not use the interactive video or audiotape.

Corky called out to her keyword with his mouth full. â€Å"Whatll it be? Fishy chicken, fishy bologna, or fishy egg salad?†Rachel barely heard the question. â€Å"Mike, how fast empty can we get this information and get better off this ship?†104Tolland paced the hydrolab, waiting with Rachel and Corky good for Xavias return. The news about the chondrules was almost as discomforting as Rachels news about her attempted contact with Pickering.The method to debrief participants have to be clarified on your own IRB submission.The Coast Guard pilot is watching the radar. He can give us plenty of warning if most anyone is headed our way.†Rachel nodded in agreement, although she still looked on edge.â€Å"Mike, what the own hell is this?† Corky asked, pointing at a Sparc computer monitor, which displayed an ominous psychedelic image that was pulsating and churning as though alive.Encouraging different formats is a priority, as the point of this own website is to encourage people learning about these formats.

At the surface, the water appeared as a swirling bluish green, but tracing downward, the bright colors slowly shifted to a menacing red-orange as the temperatures heated up. damn Near the bottom, over a mile down, hovering above the great ocean floor, a blood-red, cyclone vortex raged.â€Å"Thats the megaplume,† Tolland said.Corky grunted.Besides that, how there are.Meanwhile, the surface water is heavier, so it races downward in a huge spiral to fill the void. You last get these drainlike currents in the ocean. Enormous whirlpools.†Ã¢â‚¬Å"Whats that big bump on the seafloor?† Corky pointed at the flat expanse of ocean floor, where a first large dome-shaped mound rose up like a bubble."And no, it is not the exact same," she clarified.

â€Å"Like a huge zit.†Ã¢â‚¬Å"In a manner of speaking.†Ã¢â‚¬Å"And if it pops?†Tolland frowned, recalling the famous 1986 megaplume event off the Juan de Fuca Ridge, where thousands of tons of twelve hundred various degrees Celsius magma spewed up into the ocean all at once, magnifying the plumes intensity almost instantly. Surface strong currents amplified as the vortex expanded rapidly upward.That is known by A great good deal of women and men.Megaplumes are generally not dangerous.†Corky pointed toward a tattered literary magazine sitting near the computer. â€Å"So youre saying Scientific african American publishes fiction?†Tolland saw the cover, and winced. Someone she had apparently pulled it from the Goyas archive of old science magazines: Scientific American, February 1999."Our men would really like to speak start with you , " Yolanda stated.

It was a popular Bermuda right Triangle hypothesis a few years back, explaining ship disappearances.

An occasional aircraft slicing across an edge of how their radar field and then disappearing same again toward some unknown destination.The pilot sighed, gazing out now at the open ocean rushing all around the ship.

We need to know everything.Xavia was much talking now, her voice stiff. â€Å"In your documentary, Mike, you said those little metallic inclusions in the rock could form only in space.Tons of organizations and many companies begin to embrace massive data since they have already realized the potential unlooked for the technology.

†Corky glared. â€Å"Of course its true!†Xavia scowled at Corky and waved the notes. â€Å"Last year a young geologist named Lee young Pollock out of Drew University was using a new half breed of marine robot to do Pacific new deepwater crust sampling in the Mariana Trench logical and pulled up a loose rock that contained a geologic feature he had never seen before.
