CHAPTER TWO LITERATURE REVIEW 2. 0 Iintroduction This chapter will explain about related literature review,theoretical frame work, empirical studies as well as research gap 2. 1 Theoretical argument According to H. F Moore and F. B Kalupa (2005 :84-85) communication is the process of transmitting meaning between individuals. All human society is founded upon the human beings’ capacity to transmit intentions, desires, feelings, knowledge and experience from person to person. Second communication refers to the technical means of indirect or medicated communication embracing media from tribal drums, smoke signal and stone tablets to telegraphy printing, broadcasting and films. According to them, communication can be refer in different meaning depending on how it is used and the context. First, communication refers to the special process that makes interactions with human kind possible and enables individuals to be social beings. Communication must involve two/more processes, it is a tow-way exchange to information and understanding is applied. For example, a bulleting-broad announcement is not communication only when the announcement has been made, understanding and knowledge complete the true communication. Therefore even if we use adverts, seminars, face to face meetings and so forth, communication is effective when we get intended feedback and when an idea gets out of our mind into another Effective communication with employees, customer share holders, community neighbors and other publics is essential to good public relations. Relation with people is only established through communication with them. When communication is poor, misunderstanding and the like hood of conflict result. Barriers of successful sharing of thoughts among people in industry, labor, education, the community and government must be overcome by effective communication †¦. For a organization to have good performance it needs to have effective communication inside and outside the organization. Internal communication refers to the exchange between organization management and the internal publics that is the employees. External communication has to do with external public that are consumers, community, neighbors, dealers and distributors, suppliers, government agencies and legislators, educators and the like. The rapid growth of business organization has created various problems in both areas, external communication and internal communication. Communication with consumers, community neighbors, educators and government is increasing in volume and effectiveness. Employee is to be well informed about corporate policies so that they can communicate with the outside publics, communication involves three elements. The sender, the medium of communication and the receiver. The effectiveness of communication depends upon all three elements. If the sender is incompetent on the signal and the communication process fails. Communication is a responsibility of every employ of the institutions. It can be delegate solely to a public relation department everyone should participate, the president, staff and line management, and all rank of file employees. Employees and line executives communicate downward from lower to higher authority, competing the circuit of two – way communication at all levels of managements, there is also informal and horizontal cross communication between executives According to William,V (1992), the efficiency of group depends largely on how well the efforts of its members are coordinated but coordination doesn’t just happen. Satisfactory communication is necessary if possible are to achieve understanding and cooperation. And the higher one is on the organization ladder, the more time and energy he/she will likely devote to communication studies shows that aside from communicating-speaking writing, listening, reading and thinking (interpersonal communication) organization’s top administration does virtually nothing. And indeed there has been fantastic advancement in some areas with the aid of modern electronic equipments, it is possible to, receive, process, store, retrieve and reproduce information in speed to reach huge number of people in the process. If an organization is to succeed in competitive environment, its members will love to do more than just interdependence, they will have to collaborate and work together as a team. However, within many firms a technology skill is critical and grows more. But these skills alone will not guarantee the organization success. Above all, members of the organization must not â€Å"undo† each other. They must avoid every destructive form of competition. Some organization members are infighters back stabbers, or rumor managers. Such members at least in the short run may â€Å"win†. However the organization which tolerates such behavior generally ends up paying a dangerous cost which is the long term deterioration of its human arrest According to Haney (1995:15), trust is needed within the members of an organization and it must genuinely believe that the best way to help themselves and their organization is by being trusted of others and being trust worthy themselves. Communication includes non-verbal communication which might help in establishing trust. But also it suggests how communication/poor communication can lead to destruction. Good communication is essential in building trust within an organization but it is also crucial in maintenance of that trust. Trust is a precious but fragile commodity, it can be very challenging to create, but it can be easily weakened and even destroyed. Once that happens, trust can be extremely difficult to restore. Therefore, if an organization is to accomplish its objectives, its members must pull together but their willing to collaborate is not enough, they must know in which direction to pull. Organization objectives’ must be universally understood and accepted by its members. So here again the communication is vital. †¦Ã¢â‚¬ ¦. Effective communication is triad consisting of leader, the members of the work group and the environment in which the work is to be performed. The leader’s job is to build an environment in which the framework can be achieved. One of the major objectives is to create and maintain credibility with the group work. Four factors influence this effort: drive, dependability, competence, and credibility. This effort is important in formal organization because its purpose is to provide specific instructions about the duties of the job and how to perform them. To provide the employees with rationale of doing particularly job an understanding about how that job relates to other jobs to provide necessary data regarding the procedures policies and practices of the organization, to provide performance feedback to employees regarding how they are doing and to provide information that will convey a sense of mission and an understanding of corporate goals. †¦.. Information is provided quickly and in a direct, face to face manner when presented orally, written method communication is more formality and permanent and quite often that is what formal communication is all about, the disadvantage for this is that the dozen of memos are sent weekly and effective downward communication can help improve organization performance. ( both writer and oral communication can complete the process of information downward the organization). However, management also need to focus on ways to improve upward communication the information flow from subordinates to superior. The main benefits for upward communication include: a. Feedback regarding employees’ altitudes and feelings b. Suggestions for improved procedures and techniques as well as for new ideas c. Feedback regarding how well the down ward communication system is working d. Information about production and goal attainments e. Request from subordinates for supplies, assistance and support. However, upwards communication is not seen as very effective. †¦. Effective communication is based on strategy. A manager communicates the parameter of actions to those who must act. The massage and message receivers of effective communication are based on intended economic results. Reputation is often overlooked in strategic planning. It is an attributed character that exists outside an organization and it is largely independent of it. A company can influence its reputation, but it cannot control it. Reputation is linked directly to credibility, indirectly to esteem†¦.. According to James,L (1995) Strategy and effective communication, Strategy is found together by communication which transmits goals, purposes and decisions to those who carry them out. it is inevitably found to individuals comprising an organization and how each person interprets the content of a strategy message. A company may move quickly at the top and ignore challenges of making strategic work at the bottom. Companies do not need to define their goals and strategies formally. They do not need to define them at all as long as they can communicate and gain coordinated action from participants in the economic transaction He adds that, Credibility becomes critical component of strategy when the key participant does not believe in a company’s goal and plans. A strategic message also must fit societal and governmental expectations if not, it can create dissonance. When a society expects a company to act one way and it acts in another, the company may find that public opinion, regulation and the law are thrown against it. Hence, its performance is disturbed †¦.. Traditionally, communication has been said to have four primary communication functions within the organization context a)An integrative function b)An informative function c)A command regulative function d)A persuasive function The informative function All members of the organization have the information that enable them to do their work. Informative communication is necessary to the performance of tasks, much of information desired by members of an organization has little to do with their actual tasks. For instance employee generally like to know the company’s financial standing how other division in the organization doing, how government regulations affect their organization and some of the personal achievements of employees. Such information does not assist the actual work flow in any direct sense but employees express a need to know it and the organization to know it and the organization should therefore ensure that they get it The command to regulative function A whole communication network of manuals, policies order, instructions and directives comprises the guidelines by which the entire organization is run and by its nature it only tells people what do not but at the same time rules out all their other alternatives. It is the means by which management exercises control of the system and managements’ ability to coordinate all the activities of organization depending on how well it executes this control Two characteristic of this command regulative function: one is they are peculiarly a management into prerogative. Orders and instructions always flow from superior down wards to subordinates. An order presumes the communication is in a position of authority to issue the command and to expect the receiver to comply Secondly, the content of the command and regulative message is essentially work oriented. They centre primarily on the task necessary to do one’s job. This is to say that, there must be communication system because employees at every level of organization need to know what is expected of them and what criticism are placed on their freedom to use their own judgment. Persuasive function Persuades function operates throughout the organization wherever people find it necessary to build a case for their ideas and their behaviors. Both managers and non- managers must use it. It is important to see how persuasive function supplements the command and regulative function because much of what happens in any organization happens because of persuasion rather them orders. †¦. Integrative function The whole range of communication activities designed by management to cause the employees to identify with the organization is hoped to feel that he/she is vital part of it. management has to design some channels of communication to keep the staff informed. They can use newsletters, newspapers, films and film, strips to explain the company’s financial picture/changes within the company. visits by top managements feel that building up the employees’ identification with the total company is worth the expenditure. Also the employee get sense of integrations through informal communication in the organization this is because, social relation among employees performs an integrated functions. Principles of effective communication According http://www. sideraod. com/ There are five principles which ensure effective communication the first principle is to get appropriate feedback. The second is to really connect with your audience, it is fallacy that the mere sending out of information is a communicative act. To connect with your audience you need to address their different needs as partners because communication is a two- way process. Decide what you want the outcome of your communication to be: to inform, persuade, shock, praise, criticize, shore, please, inspire. Whatever the aims is you need to plan your message medium, to trigger the emotion and cognitive responses that will ensure you engage you audience. The third principle of effective communication is to listen and understand first. Don’t send out a message until you know what your audience need. If you are concerned about the quality of somebody’s work. For example don’t, jump in and issue on official warning. First find out what the employees perception is. The fourth principle is to understand that communication is more than the surface meaning of words. You need to be able to interpret other people message. this is just another form of feedback for example, you make an announcement and your group is discussing the information with you they may feel inhabited about disagreeing openly but ready to signs because you don’t have to be openly aggressive to show disagreement: body language, kind of words they use, the tone of voice. Some body who is receptive will give you eye contact will rearm forward and will participate by asking questions , or offering to assist in some way The fifth principle is respect. To communicate with those we want to persuade we need to respect them. Just because they don’t agree with use, doesn’t make them inferior or wrong. They have cultural back grounds and history that have led them to a particular course of action. To translate that to the workplace, you will only gain the cooperation of employees if they know you respect them by not ignoring their needs and rights 2. 2 empirical literature reviews According to John Clark (2003) good communication is one of the missing ingredient to complete the essential tool for those who aspire to move into management, those who have recently taken on a managerial or supervisory role, and those who want to improve their effectiveness when dealing with people they manager or guide as well as improve their communication with other department in their company/organization. In any type of business, effective communication is essential because of information exchange and performance in organization. It is said that a business or organization is a human decision – making system in which the quality of the decision are determined by the effectiveness of communication apparatus when communication either by fax emails, telephone, text, memo or letters should ask ourselves if the message or instructions will be easily understood by the person receiving it. The most important limitations on people’s perception are often based or cultural or emotional differences. The fact that the unexpected communication may be resented is not the issue, what often happens is if the message has not actually been received at all. It has been neither hard nor seen when we communicate there are always demands that the recipient becomes some one, does things and believes something. Before we communicate we consider the recipient expectation and make reasonable assumptions about their expectation Effective communication is good for motivation. If the communication gels with the aspiration, the values and the point of view of the recipient, it is a powerful thing. However, if it goes against the goals and ambitions of that particular individual it is highly likely that the communication will either not be received at all or meet stiff resistance Communication process According http://www. amoils. com/ The message is sent to a receiver through a medium either verbally or non- verbally. The receiver then translates the words or non- verbal gestures into a concept information and return the feedback. The success of the transmission deepens on two factors content and context Content: Is the actual words/ symbols that constitutes a part of the message known as language. It should be either spoken/ write. We all interpret words in our own ways. So much so that even simple message could be understood differently. Context : is the way the message is delivered, the tone ,expressions in the sender’ s eyes, body language, hand gestures, and state of emotion (anger, fear, uncertainty, confidence and so on) As we believe what we see more that what we hear, we trust the accuracy of non verbal behavior more than verbal behavior. So when we communicate the other person notices two things: what we say and how we say it. Normally, communication is complete once we have conveyed the message properly, message hasn’t been communicated successfully unless the receiver understand it completely and this is done by using two way communication/feedback Values of communication According to Julias,T (1992) communication in our lives also say that communication has its value that are persona value which means that humans are taken into humanity which means that we gain personal identity as we communicate with others. Relationship value it means that communication is the key of foundation of relationship, also there is other value like professional value, as well as culture value which means that communication skills are important to the health of our society. 2. 3 theoretical frameworks Behavioral theory Business communication by Lehman and Dufrene,etal (1992) theory of communication include a recognition of the social situation in which an individual finds himself, he then examine the network through which communication flows and discuss the transmission and reception of information ,the individual response and his ability to make in his own behavior. Understanding of other’s personality is possible only after observation of how that person interacts with himself and others. Behavioral theory relate also to my topic because the manager of an organization is very important to understand the behavior of other workers so as to know how to control and organize the different issues in an organization through understanding the behavior of workers and through that the manager can bring positive change in organization because it become very easily for the him/her to maintain the issue of effective communication as well as to solve different problem that face organization by knowing behavior of his workers in organization. 2. 4 Research gap The other researchers concentrate much on providing meaning of communication and effective communication in an organization rather than other alternatives like identification of communication problems faced by the managers in the organization,means by which communication problems can be solved and how effective communication contribute to improve managerial performance to achieve organizational objectives, by doing so it’s now for authors to concentrate on other ways like giving out the origin, importance as well as effect of communication in an organization . this research intend to fill the gap. CHAPTER THREE 3. 0 METHODOLOGY 3. 1 Type of research The type of research used is qualitative used approach which places primary emphasis on inductive methods. This emphasis is derived from the preposition that each social system is uniquely constructed, meaning the things are different to different people (Anderson 1987:150) This approach is possible in this research in that it allows participants to present reality in their in their natural setting it is a systematic investigation that is used to understand the meaning of various phenomenon from how people perceive it (Kisilu 2006:70) Through this approach the research was able to get the information from respondents in their natural settings. The methods choosen for this research is to concentrate on respondents who will give the required information of about the importance of effective communication in improving organization performance 3. 2 Target population The target population in this research is TBL, its various publics few customers who use TBL products. The researcher takes into consideration that these people have been access of infor since they know hoe people work and communicate in their daily activities. The research choose this people because it can provide the information on if the effective communication the determinate of their organization performance. 3. 3 Sampling technique and Sample size A sample is selected populations form the whole population under study which represents the whole people. In this research sample are used with regards to problems of money, time and distance. The researcher used simple random technique which is a probability sample where each member each member of the people has on equal chance of being selected. It requires that each member of the people be dealt with in the exactly the same way. That is no fiasing, no stacking, of the deck in favor of certain member or against others (Anderson 1987:151). The sample size of the study had a total of 45 respondents The researcher selected the sample randomly form the organization and few customers depending on the scope of the study. Respondents form TSSL), 14 respondent external officials and customers and i3 respondents form various publics 3. 4 Data collection Data were collected through structural interview, questionnaire and observation. The collection technique used will add validity to the data collection than a single method 3. 5 Structure interview Interview involves presentation of oral – verbal stimuli and reply in terms of oral verbal response it can be used through personal or telephone interview. interview is good way of accessing peoples perceptions definition of situations and construction of reality The researcher interviewed the respondent ants to understand the importance of effective communication promoting the image of the organization. The researcher used structural interview because its good way that gives an opportunity for the researcher to observe and understand what the respondents explain to him/her in relation to the research topic 3. 6 Questionnaire Questionnaire consist of a number of questions printed/typed in definite order on a form or set of forms. The questionnaire can be mailed/distributed to respondents who are expected to read and understand and write down the reply it also allows respond, who are not easy approachable to be reached conveniently. The researcher uses self- administered questionnaire with both close and open questions 3. 7 Observation The research used observation so as to note facial expression and confidence of the respondents when responding questions. The information obtained under this methods related to what is currently happening it is also complicated by either the past behavior or future altitudes. So, by observing facial expression and confidence form the respondents the researcher gets more information .

American Identity The Spectrum of Skin Colors Professor Ramos Blog

American Identity The Spectrum of Skin Colors https://www.thoughtco.com/writers-of-the-harlem-renaissance-45326 Music, dance, literature, racial pride, painting and more various cultural and artistic expression began to overflow the in the 1920’s, this period known as the Harlem Renaissance. The Harlem Renaissance is immensely known for the African American community utilizing artistic and literary expression to establish a platform to advocate against the racial injustice (Standish 40s of themes constantly found in the writings released during this time period are â€Å"hope and oppression, the urban atmosphere, as well as racial pride and solidarity, and social and economic self-sufficiency† (Harden 11). Two authors who were greatly influenced and influencers during the Harlem Renaissance were Langston Hughes and Zora Neale Hurston. Langston Hughes and Zora Neale Hurston illustrate American identity physically, patiently, and pridefully in their writings â€Å"I, Too† and â€Å"How It Feels to Be Colored Me†. Langston Hughes was an African American poet, playwright and activist (Standish 46). Born February 1, 1902 in Joplin, Missouri and died in 1967 (Bailey). Although his father denied sending Hughes to school, Hughes graduated in 1929 from Lincoln University in Pennsylvania (Bailey). To this time today, Langston Hughes’s work is said by many to embody the â€Å"Harlem Renaissance’s themes of historical pain, racial pride, and artistic renewal† (Standish 46). Hughes was even considered an â€Å"unapologetic voice of black America† speaking for Harlem (Standish 41). In his poetry, Hughes mimic â€Å"the rhythms of jazz and blues music† (Bailey). At some point in Harlem, New York Langston Hughes collaborates in writing a play called â€Å"Mule Bone† with his new apprentice, Zora Neale Hurston (Russell 130). Zora Neale Hurston is one of the most influential American writers. Hurston was born in Notasugla, Alabama on January 7,1891 and died January 28,1960 (Jones 18). In 1929, she graduated from Barnard College in 1929 and was awarded fellowship by Columbia University after conducting two years of graduate work in anthropology (Jones 20). Hurston wrote novels, short stories, essays and more. In the majority of her writings, Hurston wrote about the â€Å"interior lives of southern blacks and whites, their gender relations, honor codes, and self-reliance† (Patterson 599). Hurston’s was also an anthropologist which gave her further insight in African American culture to create the fundamental writings of the Harlem Renaissance (Russell 130-131). Her writing is said to reveal her â€Å"quirky and fearless personality† but was looked down upon by others (Russell 126). Both authors illustrate in their writings American identity has no relation to the color of a person’s skin. In Langston Hughes’s poem â€Å"I, Too†, he declares â€Å"I, too, sing America/ I am the darker brother† (Hughes lines 1-2). By saying he also â€Å"[sings] America† Hughes is explaining he also identifies as American. Hughes the brings up the color of his skin, while it is darker, is just another way an American person comes to look. He what he calls himself â€Å"the darker brother† also indicating that they are part of the same family, the American family. While Hughes uses the analogy of family Zora Neale Hurston utilizes a metaphor to get the same message across. In Hurston’s short story â€Å"How It Feels to Be Colored Me† she explains, â€Å"I feel like a brown bag of miscellany propped against a wall. Against a wall in company with other bags, white, red, and yellow. Pour out the contents and there is discovered a jumble of small things priceless and worthless† (Hurston 943). Hurston is describing that while the outside of a person is different in color, their insides are made up of the same material. Both authors are arguing the physical attributions that cause stir when it comes to American Identity. They believe they are just as American as the lighter skinned Americans. When the authors are met with the racist attitudes from others, their responses are something that one would not believe. To clarify, Hughes and Hurston make it apparent in their writings that they do not mope or retaliate when others try to invalidate them of being American due to the color of their skin. In his poem Langston Hughes presents the example, â€Å"They send me to eat in the kitchen / When company comes, / But I laugh, / And eat well, / And grow strong† (lines 3-7). Being sent away from the table makes a person feel isolated and terrible but Hughes describes he does not take it to heart. Hughes rather than shed tears for being sent to solitude he grows from the abuse and will come back stronger. Zora Neale Hurston also displays no hurt when others attempt to discriminate her expressing, â€Å"No, I do not weep at the world – I am too busy sharpening my oyster knife† (Hurston 941). Hurston straight out states she does not cry to others for their pity but instead remains â€Å"sharpening [her] oyster knife†. Stating this Hurston means she is also preparing for her comeback. The authors state these cases to demonstrate that while they are not fighting back, but they are getting ready for when the right time comes, their time, whatever and whenever that may be. Through this the authors exhibit the composure and civility of American identity. Hughes and Hurston even go as far as to being a little vain when it comes to the rejection they face. In their writings, the authors explain it is wrong for others not be around them or treat them so unfairly because they believe they are not American due to the color of their skin but each author allows the slander to bounce off. Langston Hughes goes on to assure readers, â€Å"Besides / They’ll see how beautiful I am / And be ashamed – / I, too, am American† (Hughes lines 15-18). Hughes explains that those who have done him wrong, segregating him because of the color of his skin, will feel remorseful for what they have done. He goes as far as to call himself â€Å"beautiful† showing he feels no embarrassment for the color of his skin, he still is American. Hurston is also onboard exhibiting the same self-admiration in times of others disapproval. Zora Neale Hurston confidently expresses, â€Å"It merely astonishes me. How can any deny themselves the pleasure of my company?† (Hurston 943). Hurston also feels that because the Americans of lighter sk in do not want to accompany her in any kind of way, they are the ones that miss out on enjoying her persona. Both authors show that although the American Identity, in that time period, has negative connotations of those with darker skin they themselves keep living their own lives allowing the others to deal with their negative mindsets because they know they are American. Langston Hughes and Zora Neale Hurston wrote â€Å"I, Too† and â€Å"How It Feels to Be Colored Me† in a more positive perspective in order to show that while at first, they are not thought as part of the American identity, they truly are. Although these pieces of writing are written during the time period of the Harlem Renaissance that does not make them irrelevant today. The harmful terms and actions that these authors faced in their time do not compare to what a person of dark skin has to deal with today but there is still racism that affects people, of all skin colors, toady. This positive attitude that the authors demonstrate in their writings is a lesson to be taken, society continues to make a change for the better just as American Identity has changed over time with an infinite spectrum of skin colors.

Pero puede suceder que la ESTA no sea aprobada o que sea revocada. En este artà ­culo se explica quà © hacer si el viaje no es autorizado a embarcar. Quà © es la ESTA La ESTA  es una autorizacià ³n electrà ³nica que permite a los ciudadanos de ciertos paà ­ses a viajar sin visa a Estados Unidos por un mximo de 90 dà ­as no que no se pueden alargar y cuando el objeto del viaje es hacer turismo, negocios o recibir atencià ³n mà ©dica. Este es el listado completo de paà ­ses cuyos ciudadanos pueden viajar sin visa. Verificar ese enlace para informarse sobre las nuevas reglas que afectan a los ciudadanos de esos paà ­ses con doble nacionalidad con ciertos estados y tambià ©n a los que han viajado a paà ­ses considerados problemticos. Adems tener en cuenta que podrà ­an viajar con la ESTA los ciudadanos de otro paà ­s en el que viven habitualmente pero que por la razà ³n que fuera, como por ejemplo por herencia de sus padres, tienen tambià ©n el pasaporte de uno de esos paà ­ses. Resultados que se pueden obtener al llenar el formulario de  la ESTA La ESTA se rellena por internet  en la pgina official del gobierno americano. Generalmente el resultado se conoce al momento y puede ser de tres tipos: Viaje autorizado. En este caso ya se puede viajar por aire o mar. Hay que tener un billete de ida y vuelta y se recomienda imprimir la autorizacià ³n porque contiene el nà ºmero de solicitud, que puede hacer falta posteriormente. Aunque la  aerolà ­nea no lo necesita, ya que el Departamento de Estado es la que se encarga de notificarla de que una determinada persona est autorizada a embarcar hacia Estados Unidos, algunas insisten en pedirlo.Autorizacià ³n pendiente. En este caso, volver a entrar en la pgina web pasadas 72 horas y se ver el resultado definitivo.Viaje no autorizado. Esto le puede pasar incluso a las celebridades de fama internacional, cuya causa ms comà ºn para no aprobase su ESTA o su visa es el consumo de drogas. Quà © hacer si la ESTA seà ±ala que el viaje no es autorizado Llenar un formulario para iniciar el proceso para solicitar una  visa de turista que se tramitar en la embajada o consulado correspondiente. El  oficial a cargo tendr la à ºltima palabra para decidir  si la concede o rechaza la peticià ³n. En este à ºltimo caso, y dependiendo de la razà ³n, ser posible solicitar un perdà ³n o waiver para los casos de inadmisibilidad. Sin embargo, para las razones que convierten a una persona en inelegible no hay posibilidad de pedir perdà ³n. Cules son las razones por las que la ESTA no autoriza el viaje Las razones pueden ser varias, como haber estado previamente en Estados Unidos y no salir a tiempo, aunque el retraso sea de sà ³lo unas horas. Tambià ©n puede haberse dado el caso de que se hubiera impedido el ingreso en una fecha anterior, por razones varias, como por ejemplo, por estar ingresando con demasiada frecuencia.   Tambià ©n puede ser porque previamente se ha denegado una visa, esto es relativamente comà ºn en el caso de personas con doble nacionalidad, que piden un visado con un pasaporte y cuando es rechazado intentan viajar a EEUU con el pasaporte espaà ±ol y la ESTA. Otra causa puede ser la condena por determinado tipo de delitos u otras muchas causas que hacen a una persona inadmisible para entrar a USA.   Por à ºltimo la ESTA puede negarse o el ingreso a Estados Unidos cuando se viaja con dicha autorizacià ³n cuando la intencià ³n de su titular es casarse en el paà ­s con un ciudadano americano o con un residente permanente legal y quedarse mientras se arreglan los papeles mediante el denominado ajuste de estatus. Y es que la intencià ³n con la ESTA no puede ser casarse. Y si bien es cierto que actualmente se permite un camino para que puedan arreglar los papeles las personas que se casan en Estados Unidos con estatus de turista, no es menos cierto que hay muchos problemas si no se respetan ciertos plazos. A tener muy en cuenta El fin de viajar a EEUU sin visa es turismo, negocios o atencià ³n mà ©dica. Por lo tanto, las personas que la utilizan para estudiar inglà ©s a tiempo completo por unas semanas tienen que saber que se arriesgan a tener problemas migratorios, porque no estn cumpliendo con la ley. Les corresponde una visa de estudiante.Asimismo, los periodistas, artistas, actores y atletas que desean viajar a EEUU por motivos profesionales deben pedir sus visas correspondientes.  Por supuesto que si se ingresa a Estados Unidos con una ESTA no se puede trabajar. Si se hace, se est cometiendo una violacià ³n migratoria que, si se descubre o se sospecha, puede tener consecuencias graves.En realidad, tampoco se puede ingresar al paà ­s con una ESTA cuando la intencià ³n es buscar trabajo. La intencià ³n es, afectos de leyes migratorias, muy importante ya que si las autoridades creen que existà ­a esa intencià ³n puede haber problemas.Tener una ESTA no garantiza la entrada en Estados Unidos. Al llegar a las Aduanas y Fronteras el oficial de inmigracià ³n tiene la à ºltima palabra para decidir quià ©n entra. Es importante saber que en la actualidad una de las causas principales  por la que se deniega la entrada en las aduanas es que van a estudiar y para eso necesitan una visa que no tienen.

Working in groups Essay Example | Topics and Well Written Essays - 250 words

Working in groups - Essay Example Successful group work requires tolerance, inclusivity and assertiveness to achieve the desired goal. Group communication is known as the interaction of three or more interdependent people who work towards a certain goal. Successful groups learn how to balance the contradictory and competing forces that operate in that group. The entire group should be able to work should know their roles and be able to establish professional rapport with other members of the group (Ephross 56). The merit of working in a group is the group members learn a great deal from each other thereby performing better than individual working alone. The demerit is conflicts may be difficult to solve. When I was in high school, I had difficulties in understanding Chemistry but good in Mathematics. My friends and I decided to form a study group. In this group I found out that there were people who were good in Chemistry but poor in Mathematics. We helped each other and by the time the final exam reached, we were well prepared and the entire group member excelled. Steinberg’s book, The mutual-aid approach to working with groups offer imperative information on how effective a group can be. The key message that is passed across is forming a group that works for you and establishing clear goals. The group member should know each other so as to avoid misunderstandings (Steinberg 78). In conclusion, group work requires tolerance, inclusivity and assertiveness to achieve the desired goal. For any group to work effectively, all members should understand their roles within the group. Each member should actively contribute towards the set goals. The group members should be able to solve any issue that comes up amicable. To be able to do this, there should be effective communication amongst all group members. Without communication there is nothing constructive that that can take place in a

EBay's Overall Digital Marketing Efforts Case Study

EBay's Overall Digital Marketing Efforts - Case Study Example With up to 4.5 million likes on Facebook and over 170 thousand followers on Twitter, eBay is actively increasing its popularity all around the world. It has a modern website that is quite user friendly, it easy for one to find his or her way around the site be it to buy or sell a phone, a car or an accessory among others. Consequently, its default search engine gives results of all its networks; the item to be sold or bought, the price range and the even geographical location. Finally, eBay has a mobile application that allows e-mail and message notifications about specific services (O’Reilly, 1). The New York Times has featured news about eBay. Buying a few items on eBay guarantees one to be conversant with the mechanisms and operations of the site. More information and ideas were outsourced from other people who have used eBay before or are still using. Overall Marketing Strategy A marketing strategy refers to the process(s) or model(s) that a company employs to realize sust ainable competition and maximize their sales, by optimally using their resources. This would include all the short and long term ideologies in the marketing area, strategy formation, assessment and selection of a good plan, hence to help the organization reach its goal. Marketing, therefore, entails the efforts used to get word out about a product. O’Reilly (1) claims that, no matter how big the brand, the products they have a need to be showcased to the rest of the globe to at least get a hearing. These strategies include: spreading the news, using e-mail, allowing for customer feedback, using business cards, rewarding frequent customers and giving out freebies. These ideas enable one to make an overall marketing plan, but with a good website the number of these strategies can be doubled. Located all over Europe, eBay has got more than 90 million users worldwide. As a marketing plan, it launched daily email offers service, and is focusing to push fashion sales. With its slog an, ‘free shipping’, eBay has been able to significantly attract sellers and buyers from all over U.S. eBay. It redesigned its website into a superstore. Recently, Sainsbury’s digital marketer, Tanya Lawler joined eBay to be the vice president in order to boost sales says O’Reilly, (1). Target Audience eBay is one of the largest online marketplaces all around the world. It allows trade to occur on local, national and even international scale. This trade happens through auction listings, buy it now basis or through the eBay stores. It has acted as a neutral intermediary between buyers and sellers, hence referred to as a market maker. eBay oversees trade between a number of goods and services namely; motors (cars, motorcycles, bicycles etc.), fashion, Electronics, collectibles or art, sporting goods, toys and hobbies, jewelry, health and beauty, deals and gifts and finally, home, outdoors and decor (Ebay.com, 1). A number of eBay users find it safer than oth er online marketplace, it is, therefore, considered a reliable online source for buying and selling of goods and services. eBay offers free shipping within the U.S while rival online marketplaces do not offer such service. eBay differentiate itself by getting involved or acting as a mediator between the two parties (buyers and sellers), hence the idea of auctioning goods and services.  

Carl Linnaeus Essay Example for Free

Carl Linnaeus Essay Linnaeus Report Born in 1707 to a country parson in Rashult, southern Sweden, the young Linnaeus showed a keen interest in plants and flowers and by the age of eight, was given the nickname ‘the little botanist’. Linnaeus studied medicine, first at the University of Lund and then at the University of Uppsala. Medicine at this time was based on herbals so it meant he also studied plants. He shared his passion for plants with Olaf Celsius whom he met at Uppsala. Linnaeus is most widely known for creating systems for naming and classifying plants and animals. Realizing that new plants were being discovered faster than their relationships could be established, he first came up with a simple classification based upon the number of floral parts of each plant. This system remained popular into the nineteenth century. Gradually Linnaeus also developed a system of names in which each species of plant and animal had a genus (class or group) name followed by a specific name. For example,  Plantago virginica  and  Plantago lanceolata  were the names of two species of  plantain  (an herb). Botanists agreed in 1905 to accept his  Species plantarum  (1753) and zoologists (scientists who study animals) agreed to accept his  Systema naturae  (1758) as the official starting points for scientific names of plants and animals. He  was one of the most influential scientists of his time. His  theory of classication allowed for clear and easy descriptions of plants, animals and minerals. So straightforward was his new naming system, it is still used by scientists today.

Security in Healthcare: How Bring Your Own Device (BYOD) violates Healt

Bring Your Own Device policy (BYOD) in health care organizations is a growing trend that shows a considerably positive effect that few people could notice any violations that may accompany it. The policy allows staff in an organization to carry their personal electronic devices like mobile phones, computers, and laptops to facilitate their work by helping store and access certain information (Herzig 20). Health Insurance Portability and Accountability Act (HIPAA) was enacted in 1996. It entails security and privacy regulations constructed to ensure good security measures are applied to protect patient data in health facilities, especially where BYOD policy is active. The policies provided in HIPAA also ensure that only authorized people access information stored in the devices used by health providers (Powell 1-2). HIPAA security regulations offer standards for ensuring that patient data on electronic devices are safeguarded. HIPAA cover how we can use and disclose patient information while the HIPAA privacy policies explain how patient information should be accessed and disclosed. Schneider (55) reviews that violation of HIPAA security and privacy laws majorly entail the attainment, retrieving and using medical information by a person who is not subject to the health data or is not permitted to offer medical services. How BYOD can violate HIPAA security/privacy laws Lack of Confidentiality BYOD policy may not promote confidentiality and integrity, which is a major requirement in the HIPAA regulations (Health Information Privacy). Health providers should come up with strategies to follow up on and protect information they have concerning their client. 5111 Physical Security Policy ensures that the security of the devices used by ... ...Security in Healthcare: Building a Security Program.

A Wrinkle in Time Novel

Madeleine L’Engle’s novel A Wrinkle in Time is about a young girl named Meg Murry, who is far from perfect. While she does come from a close, loving family, Meg has low self-esteem and a stubborn personality. As she gets caught up in the battle to save the universe from evil, Meg uses both her strengths and her weaknesses to help her. The novel begins by introducing Meg as a girl who has very low self-esteem.L’Engle describes Beg making horrible faces at herself in the mirror, flashing a snarling smile of braces and messing up her mouse-brown hair. If Meg sighing loudly at her own reflection isn’t enough to convince the reader that Meg doesn’t like herself, the scene when she yells, â€Å"I hate being an oddball! † should prove the point. Though Meg doesn’t feel good about herself, she does care deeply about her family. She worries about her missing father and eventually goes to Camazotz to save him.While she’s tessering around the universe, Meg sees her mother crying back on Earth. Meg’s love for her mom is so strong that she reacts by getting angry, gaining more strength to use in the battle against evil. In the end, it is Meg’s love for her brother Charles Wallace that gives her the power to save him from IT. Throughout the novel, people tell Meg hat she’s too stubborn. She gets in trouble in math class because she refuses to show her work and do problems the teacher’s way.She’s even stubborn when she’s sent to the office, and Principal Jenkins tells her to â€Å"†¦be less antagonistic. † But it is this stubborn quality that keeps Meg going in the fight against the Man with Red Eyes. A less strong-willed person would have backed down from fear when faced with such an evil character. In conclusion, Meg is such an interesting character because she is not perfect. She is a stubborn girl with low self-esteem, but her love for her family helps her use her weaknesses for strength.

INTRODUCTION Dalton's Law of Partial Pressures states that for a mixture of gases in a container, the total pressure is equal to the sum of the pressures of each gas. Where P1 is the partial pressure of gas 1, P2 is the partial pressure of gas 2, and so on†¦ OR In the experiment of the steam distillation,we applied the Dalton’s Law of Partiaal Pressure combined with Ideal Gas Law.Steam distillation is a special type of distillation (a separation process) for temperature sensitive materials like natural aromatic compounds. Steam distillation is employed in the manufacture of essential oil, for instance, perfumes. In this method steam is passed through the plant material containing the desired oils. It is also employed in the synthetic procedures of complex organic compounds. Eucalyptus oil and orange oil are obtained by this method in industrial scale. Figure 1 : Laboratory set-up for steam distillationDistillation Temperature and Composition of Distillate As with ordinary distillations, the boiling point is the temperature at which the total vapor pressure equals the atmospheric pressure. If the vapor pressures of the two components are known at several temperatures, the distillation temperature is found readily by plotting the vapor pressure curves of the individual components and making a third curve showing the sum of the vapor pressures at the various temperature. The steam distillation temperatures will be the point where the sum equals the atmospheric pressure.K nowing the distillation temperature of the mixture and the vapor pressures of the pure components at that temperature, one can calculate the composition of the distillate by means of Dalton’s law of partial pressures. According to Dalton’s law, the total pressure(P) in any mixture of gases is equal to sum of the partial pressures of the individual gaseous components (? A , ? B, etc). The proportion by volume of the two components in the distilling vapor will consequently be equal to the ratio of the partial pressures at that temperature; the molar proportion of the two components (?A and ? B) in steam distillation will be given by the relationship ? A/? B = ? A/ ? B, where ? A + ? B equals the atmospheric pressure. The weight proportion of the components is obtained by introducing the molecular weight (MA and MB) Weight of A / weight of B = (? A x MA) / (? B x MB) Example . Consider a specific case, such as the steam distillation of bromobenzene and water. Since the su m of the individual vapor pressures (see Figure below) attains 760 mm at 95. 2? , the mixture will distill at this temperature. At 95. 2? the vapor pressures are bromobenzene, 120mm and water, 640mm. ccording to Dalton’s law, the vapor at 95. 2? will be composed of molecules of bromobenzene and of water in the proportion 120:640. the proportion by weight of the components can be obtained by introducing their molecular weights. Weight of bromobenze / weight of water = (120 x 157)/(640 x 18) = 1. 63/1. 00 Bromobenzene= {1. 63/(1. 00 + 1. 63)} x 100% = 62% Water = {1. 00/(1. 00 + 1. 63)} x 100% = 38% The weight composition of the distillate will therefore be 62% bromobenzene and 38% water. OBJECTIVE To demonstrate a separation of a mixture by using steam distillation MATERIALS/APPARATUS/EQUIPMENT 00 ml round-bottomed flask, 50 ml Erlenmeyer flask, stoppers, naphthalene, salicylic acid. METHOD Steam Distillation of Turpentine 1. The apparatus for steam distillation are arranged a s shown in Figure 1. 50 ml of distilling flask and 10 ml graduated cylinder is used as the receiver. 2. In the flask, 5 ml, (4. 3g) of turpentine ( bp 156-165 at 760 mm) and 15 ml, of water is placed. 3. Two boiling chips are added and the heating mantle is adjusted to give vigorous boiling. It is essential for the success of this experiment that the mixture boiled rapidly with good mixing of the two phases.Because the point of this experiment is to measure an equilibrium composition and the initial distillate may not have time to equilibrate, the first 1. 5 ml of distillate is discarded and the next 5 ml is collected. 4. The volumes of the water and the turpentine layers at this distillate are recorded. 5. The ratio of the volumes actually found is compared with the ratio calculated from the ideal steam distillation law using the tabulated vapor pressure and densities. 6. The distillation temperature observed is compared with the calculated value.

What properties must a substanc e have for a steam distillation to be practical? For steam distillation of a substance to be carried out, the substance must be heat sensitive. It must possess a lower boiling point than water.This method is also advisable for highly volatile liquids because highly volatile liquids denatures at high temperatures. 2. What are the advantages and the disadvantages of steam distillation as a method of purification? Among the advantages of steam distillation is organic compounds which is steam distilled will evaporate at lower temperatures, most probably below their temperature of denaturation. Besides that, heat sensitive aromatic compounds which cannot be distilled by direct heating can be processed. On the other hand, the disadvantages of this method are this method is not exactly suitable for all types of aromatic oils.Only certain types of aromatic oils are suitable to be processed using this method. Furthermore the heat is difficult to control causing the rate of distillation to be variable. -Our group apparatus got some problems. The turpentine that has been distillated accumulated at the joint of the apparatus. This is because the apparatus less slope, leads the turpentine to accumulate, resulting long time to collect the distillated turpentine. CONCLUSION Steam distillation is a special type of distillation (a separation process) for temperature sensitive materials like natural aromatic compounds.Many organic compounds tend to decompose at high sustained temperatures. Separation by normal distillation would then not be an option, so water or steam is introduced into the distillation apparatus. By adding water or steam, the boiling points of the compounds are depressed, allowing them to evaporate at lower temperatures, preferably below the temperatures at which the deterioration of the material becomes appreciable. Therefore, as the conclusion, it is proven that turpentine and water can be separated by using steam distillation.It is also known that water ha s a higher density than turpentine. Next, Dalton's law (also called Dalton's law of partial pressures) states that the total pressure exerted by a gaseous mixture is equal to the sum of the partial pressures of each individual component in a gas mixture. This empirical law was observed by John Dalton in 1801 and is related to the ideal gas laws. On the other hand, the ideal gas law is stated as the equation of state of a hypothetical ideal gas. It is a good approximation to the behavior of many gases under many conditions, although it has several limitationsTherefore, as both of these laws are involved, we can conclude that both Dalton’s Law and Ideal Gas Law are applicable in steam distillation. Based on the result of the experiment, water contains 80% and turpentine contain 20% portion. Some errors might have occurred during the experiment that caused the results to be differed from the theory. During the experiment, the apparatus must handle carefully because it is easily broken. To increase the accuracy of the result, thermometer is used in the flask so we can read the temperature in the flask.We must use stopper to close the flask because it can avoid the water vapour escape to the environment REFERENCES John R.

Pacific Grove, CA: Brooks/Cole Publishing Company APPENDICES Steam Distillation Experiment 2: Isolation of Eugenol from Cloves Background; Readings on Vapor pressure, Raoult’s Law from TRO: A mixture of the essential oils, eugenol and acetyleugenol, will be steam distilled from cloves. These compounds are isolated from aqueous distillate by extraction into dichloromethane. The dichloromethane solution is shaken with aqueous sodium hydroxide, which will react with eugenol, to yield the sodium salt of eugenol in the basic aqueous layer, and acetyleugenol in the organic layer. The basic aqueous layer can be acidified to re-extract eugenol from it.And the organic layer can be dried and concentrated to yield acetyleugenol The principle of steam distillation is based on the fact that two immiscible liquids will boil at a lower temperature than the boiling points of either pure component, because the total vapor pressure of the heterogeneous mixture is simply the sum of the vapor pressures of the individual components (i. e. PT = PoA + PoB, where Po is the vapor pressure of the pure liquids). This leads to a higher vapor pressure for the mixture than would be predicted for a solution using Raoult’s Law(applies for iscible mixtures) (that is PT = Po(A)n(A) + Po(B)n(B), where n is the mole fraction of the component in the mixture). The higher total vapor pressure leads to a lower boiling point for the mixture than for either single component. The boiling point of eugenol, an oil found in cloves, is 248  °C, but it can be isolated at a lower temperature by performing a co-distillation with water. Steam distillation allows separating substances at lower temperatures which is useful since many organic compounds tend to decompose at high temperatures which regular distillation would require.For steam distillation to be successful, the material to be isolated must be insoluble in water. Usually   these compounds have a low vapour pressure. After mixing them with water, however, the mixture will distil when the sum of the two vapour pre ssures reaches atmospheric pressure. It follows, then, that this must happen below the boiling point of water. Note that by steam distillation, as long as water is present, the high-boiling component vaporizes at a temperature well below its normal boiling point without using a vacuum.Since eugenol is not soluble in water, the concentration of the eugenol in the vapor over the boiling eugenol– water suspension does not depend on concentration of the eugenol. The relative amounts of eugenol and water in the vapor simply depend on the vapor pressures of the pure materials. The vapor pressure of water at 100  °C is 760 torr, and the vapor pressure of eugenol at 100  °C is approximately 4 torr; (Note, the suspension boils when it’s vapor pressure is equal to the external pressure.Since both the eugenol and the water are contributing to the vapor pressure of the suspension, the suspension will boil before either pure substance would normally boil. ) Since the distillate will contain both water and eugenol, the eugenol must be extracted from the water using an organic solvent. Once the eugenol is extracted into an organic solvent,the organic layer is separated from the aqueous layer and dried. The eugenol is finally isolated by evaporation of the organic solvent. When   the sum of the separate vapor pressures equals the total pressure, he mixture boils and P =P(A) + P(B) Where PA is vapor pressure of pure water A PB is vapor pressure of pure B 1 Then the vapor composition is Y (A)= PA/P Y(B) =PB/P Dalton’s Law: PAV1 = nART1 and PBV2 = nBRT2 V1 = V2 and T1 = T2 n = moles, The ratio moles of B distilled to moles of A distilled is OH OCH3 OAc OCH3 Eugenol AcetyleugenolObjectives: To extract Eugenol and Acetyleugeonol from cloves To separate the mixture of eugenol and acetyleugenol using their acid- ­? base properties. To characterize eugenol and acetyleugenol using TLC(Rf values) andRefractive index. Glassware: Beaker to mass the cloves, Er lenmeyer flasks(2, 50- ­? ml), storage container+ distillation glassware(there should be an assembly in the fume hood) Procedure: Week 1: Steam Distillation Place 10 g of whole cloves (ground using a mortar and pestle by the teacher) in a 100-mL round-bottom flask, add 50 mL of water, and set up an apparatus for simple distillation- steam (will be set up in the fumehood and you can draw the set up while in the lab) will be generated in situ(50 ml of water added to the flask will generate the steam).Heat the flask until boiling begins, then reduce the heat just enough to prevent foam from being carried over into the receiver. Use a 50-mL Erlenmeyer flask as a receiver(the distillate will collect in the flask thro a funnel) and transfer periodically your distillate to a 50-mL graduated cylinder. While you have removed one receiver, do not forget to replace the Erlenmeyer flask with a second one(that is clean and dry). 2 Caution: It is important that the cloves remain covered with wa ter at all times. Or else, the cloves will burn and smoke!Also, the distillation has to be steady. If not the mixture will foam and the foam will drop down the condenser into the receiving flask. And this would contaminate the distillate. Save the distillate in a tightly capped bottle for the following week. Week 2: Separation of Eugenol and Acetyleugenol via acid/base extraction Place the 50 mL of distillate in a 125-mL separatory funnel and extract with three 10-mL portions of dichloromethane. Combine the dichloromethane extracts and reserve 1 mL for thin layer chromatography. teacher will explain this step) To separate eugenol from acetyleugenol: pour back the dichloromethane extracts into the separatory funnel, extract the dichloromethane solution with 5% aqueous sodium hydroxide solution. Carry out this extraction three times, using 5-mL portions of sodium hydroxide each time. KEEP the aqueous extracts (it contains eugenol) and dry the organic layer over sodium sulfate (add eno ugh so the drying agent no longer clumps together but appears to be a dry powder as it settles in the solution).Swirl the flask to complete the drying process and let the drying agent settle for 1 minute before decanting into a DRY and TARED Erlenmeyer flask, rinse the drying agent with two 2-mL portions of dichloromethane. Evaporate the solution on a steam bath, the residue should be aetyleugenol. Acidify the combined aqueous extracts to pH 1 with concentrated hydrochloric acid (use Litmus paper to monitor the pH), and then extract the eugenol with three 5-mL portions of dichloromethane.Dry the combined extracts over sodium sulfate, as done before, decant into a DRY and TARED Erlenmeyer flask, and evaporate the solution on a steam bath, the residue should be eugenol. Cleaning Up: Combine all aqueous layers, neutralize with sodium carbonate, dilute with water, and flush down the drain. Any solutions containing dichloromethane should be placed in the halogenated organic waste contain er. Wash up all glassware with soap and water. Analysis: Calculate the weight percent yields of eugenol and acetyleugenol oils based on the weight of cloves used. Analyze your products sing refraction index. Analyze your products using thin layer chromatography (TLC).

Then the TLC plate is developed. For the next step (co-spotting), an authentic sample of the 3 ompound closest in Rf value to the unknown is chosen. TLC co-spotting of a second plate allows for preliminary identification of your compound. Three spots are applied to the adsorbent on the baseline of the TLC plate: the purified unknown, an authentic sample, and a co-spot of unknown and authentic sample. If the developed TLC plate shows only one row of spots, it can be concluded that the unknown has been purifed, and that the unknown is possibly the same compound as the authentic sample.However, because Rf values are relative, not absolute, some compounds may have very similar Rf values Pre- ­? ab: FOR WEEK 1 only: All the required formulae for the caculations have been presented here.

The Failure of the League of Nations essays

The Failure of the League of Nations essays In the beginning of the 1930's, there was a world-wide economic depression. This lead to the creation of expansive policies of strong countries, such as Japan and Italy, in order to overcome the depression by building strong empires. The League of Nations dependent on the obedience of the Covenant by its members in order to succeed. However, in 1930's the League failed in stopping dictators deliberately breaking the Covenant. Already in 1931, Japan controlled most of the economy in Manchuria, part of China. It owned the most important assets in Manchuria, such as the Manchurian Railway. As the world-wide depression hit Japan hardly, the Japanese saw the invasion as the only way how to get out of depression. During the night of 28th September, an explosion of the Manchurian Railway, gave the Japanese an excuse to occupy the city of Shenyang. Instantly, China asked for the help of the League of Nations. After having a close look at the case, the League ordered the Japanese troops to leave Manchuria. The Japanese government agreed with the League's decision. However, the Japanese troops were already settled in Manchuria and refused to withdraw. The government no longer had control over its army and the army continued to advance in Manchuria. This event was a major blow to the League. The League was meant to keep peace by collective security, however, the Japanese refused to accept the terms of the League. Thus, this meant that if persuasion did not work then the League had to use economical sanctions. However, personal interest played a major role in the failure of applying economical sanctions on Japan. Both Britain and France, the main leaders of the League, were also recovering from the Great Depression and they did not want to risk losing trade with Japan, as it was vital for their economy. It soon became clear that economical sanctions could not work. Therefore, the League was left with their last resource&qu...

Business Ethics

Business Ethics Essay Ethics in Business From a business perspective, working under government contracts can be a very lucrative proposition. In general, a stream of orders keep coming in, revenue increases and the company grows in the aggregate. The obvious downfalls to working in this manner is both higher quality expected as well as the extensive research and documentation required for government contracts. If a part fails to perform correctly it can cause minor glitches as well as problems that can carry serious repercussions, such as in the National Semiconductor case. When both the culpable component and company are found, the question arises of how extensive these repercussions should be. Is the company as an entity liable or do you look into individual employees within that company? From an ethical perspective one would have to look at the mitigating factors of both the employees and their superiors along with the role of others in the failure of these components. Next you would have to analyze the final ruling from a corporate perspective and then we must examine the macro issue of corporate responsibility in order to attempt to find a resolution for cases like these. The first mitigating factor involved in the National Semiconductor case is the uncertainty, on the part of the employees, on the duties that they were assigned. It is plausible that during the testing procedure, an employee couldnt distinguish which parts they were to test under government standards and commercial standards. In some cases they might have even been misinformed on the final consumers of the products that they tested. In fact, ignorance on the part of the employees would fully excuse them from any moral responsibility for any damage that may result from their work. Whether it is decided that an employees is fully excused, or is given some moral responsibility, would have to be looked at on an individual basis. The second mitigating factor is the duress or threats that an employee might suffer if they do not follow through with their assignment. After the bogus testing was completed in the National Semiconductor labs, the documentation department also had to falsify documents stating that the parts had surpassed the governmental testing standards. From a legal and ethical standpoint, both the testers and the writers of the reports were merely acting as agents on direct orders from a superior. This was also the case when the plant in Singapore refused to falsify the documents and were later falsified by the employees at the have California plant before being submitted to the approval committees (Velazquez, 53). The writers of the reports were well aware of the situation yet they acted in this manner on the instruction of a supervisor. Acting in an ethical manner becomes a secondary priority in this type of environment. As stated by Alan Reder, . . . if they the employees feel they will suffer retribution, if they report a problem, they arent too likely to open their mouths. (113). The workers knew that if the reports were not falsified they would come under questioning and perhaps their employment would go into jeopardy. Although working under these conditions does not fully excuse an employees from moral fault, it does start the divulging process for determining the order of the chain of command of superiors and it helps to narrow down the person or department that issued the original request for the unethical acts. The third mitigating factor is one that perhaps encompasses the majority of the employees in the National Semiconductor case. We have to balance the direct involvement that each employee had with the defective parts. Thus, it has to be made clear that many of the employees did not have a direct duty with the testing departments or with the parts that eventually failed. Even employees, or sub-contractors, that were directly involved with the production were not aware of the incompetence on the part of the testing department. READ: Comparison Of The Piano Lesson And Sonnys Blues Essay For example, the electrical engineer that designed the defective computer chip could act in good faith that it would be tested to ensure that it did indeed meet the required government endurance tests. Also, for the employees that handled the part after the testing process, .

Current Events in International Entrepreneurship Essay

Current Events in International Entrepreneurship - Essay Example What is observable is the general rise in the Total Early-stage Entrepreneurial Activity throughout the world between the year 2010 and 2011 which contradicts with the experience in previous years. While efficiency-driven economies improved by nearly 25%, innovation-driven economies followed with a 22% increase. In fact, there are various factors that can be measured in order to understand entrepreneurship in a nation. The first one among them is the percentage of working age population who own or are engaged in setting up a new business. In addition, it is helpful to understand the informal investment rate. It means the percentage of the population who has personally invested in the business run by some other one. According to the GEM 2011 Global Report, some other important measures are the percentage of ventures with new products and new services, the percentage of foreign customers, and people’s belief about the chances for setting up a new business in their country. In or der to understand the situation in the nation, it may also be useful to assess people’s attitude towards new entrepreneurs in the society. It can be understood by checking if people believe entrepreneurs get high status in the society. Another vital measure is the involvement of media. For example, people’s perception of the degree of media exposure new successful ventures get has an impact on the entrepreneurship in total. 2. Entrepreneurial Ecosystem and Its Components In fact, the entrepreneurship ecosystem consists of six domains which effectively classify the hundreds of elements the ecosystem. They are conducive culture, enabling policies and leadership, availability of appropriate finance, quality human capital, venture-friendly markets, and infrastructural supports. The mere fact is that each ecosystem is in fact unique in nature with its own features. For example, in Taiwan, the ecosystem developed in the context of a huge accrual of highly successful Taiwanes e expatriates in the US. Similarly, the Chinese ecosystem is marked by a totalitarian government and diverse regional policies. Another interesting point is that a time comes when an entrepreneurship ecosystem becomes self-sustaining in nature. To illustrate, when it is found that all the six domains are strong enough to reinforce mutually, it is possible for the government to reduce its control over the market. As Isenberg points out, the various domains of entrepreneurship ecosystem can be identified as leadership, government financial capital, early customers, networks, labor, educational institutions, infrastructure, support professions, nongovernment institutions, societal norms, and success stories. Out of these factors, the leadership helps through social legitimacy, support, and policies. Also, there can be investment support, regulatory frameworks, and tax benefits. While educational institutions help in the form of special entrepreneurship training and degrees, societal no rms help through tolerance of risk, mistakes and failure. 3. Entrepreneurial Finance across the World It is generally found that in all countries, young and new firms have les dependence on bank financing and are more inclined towards informal financing. However, it is seen that in those nations with strict rules and better credit information, the
