Immigration - Personal Statement Example I want to help people in the future who may face tribulations the same way she did. I want to be a legal professional who can stand up for the rights of all of the downtrodden, and those in difficult situations. I also want to achieve social change and equality. I ask myself what can I do as one person to change any situation. The answer is that I can do everything as long as I accept the challenge of being an agent of change regarding social progress for families and children, for the continuing pursuit of social justice through law, with a personal focus on divorce law and immigration. In terms of the growth and change I have experienced while vicariously experiencing my mother's divorce as a child, I learned my legal internship that being involved in legal work requires a great deal of leadership and determination; leaders in the field must ensure the success of their clients in every way possible by being effective team players who can make definitive, goal-oriented decisions based on skills and experience I have also learned through experience that it is not only dreams of success that bring people to the field of law. I care deeply about what happened to my mother in her divorce, and what happens to many.

Case study World Bank Essay Example | Topics and Well Written Essays - 750 words

Case study World Bank - Essay Example The Forbes Capital Hospitality Index (FCHI) measures macroeconomic indicators like GDP growth and international trade, along with societal factors affecting investment, including poverty, bureaucracy, technological advancement, and corruption." (Ravindran) World Bank has been actively involved in setting the right scene for economic development within countries on an international platform. There is a general agreement that corruption within the country can be controlled by taking active measures to involve civil societies, but the degree of involvement is still a matter of consideration. "Social marketing can make an important contribution to the creation of atmosphere in the public life that discourages fraud and corruption" (Kindra & Stapenburs, 1998) Social marketing can be used in public health campaigns (e.g., to reduce smoking and alcoholism, safe sex, and increasing physical fitness), environmental campaigns (e.g., fighting pollution, promoting recycling, saving water and power), education campaigns (to encourage literacy), and the protection of individual/group rights (e.g., racial and gender equality, gay and lesbian rights). Societal marketing based on ethical and philanthropic principle can achieve this dynamic change within a society, community and a country by raising the awareness of the citizens about the costs of the corruption to the country, addressing the concern about institutions within a country, increasing understanding regarding the factors of corruption within public behavior. World bank has taken a morally good stand to change the international scene for more humane endeavors, its contribution id noteworthy and has been a source of admiration and inspiration for many other world forums in guiding their decisions related to international trend in growth and expansion. The premier business publication said: "As access to capital markets around the world becomes commonplace for individual investors and multinational institutions alike, the race is on for countries to attract the foreign investment capital needed to fuel the engines of growth at home. Addressing this need for a "one-stop reference", Forbes began with a list of principles employed by the US Chamber of Commerce when considering international investments. FORBES has listed Denmark, Finland, Iceland, the US, the UK, Singapore, Australia, Estonia, Ireland, and New Zealand as the top 10 countries in the world in terms of capital hospitality. (Ravindran) ACT-UTILITARIANISM: Mill is an advocate of Utilitarian principle, Mill was especially impressed by the work of Jeremy Bentham. He agreed with Bentham when he argued in Introduction to the Principles of Morals and Legislation (1789), that the proper objective of all conduct and legislation is "the greatest happiness of the greatest number". Mill became a Utilitarian and at the age of seventeen formed a discussion group called the utilitarian Society. Mill argues that the moral worth of actions is to be judged in terms of the consequences of those actions and our moral feelings often conflict with our inclinations of self-interest. He aimed to show humans the way the world is and how they could accommodate themselves to it and to one another. His aim was the improvement of humankind. His guide was the

Globalization of North America, South America and the Caribbean Essay Example for Free

Globalization of North America, South America and the Caribbean Essay Globalization is the result of a development of an increasingly integrated global economy marked especially by free trade, free flow of capital, and the tapping of cheaper foreign labor markets (http://www. merriam-webster. com/dictionary/globalization). Not everyone is a proponent of globalization. This is especially true for North America. Although the textbook says North Americans have become a highly affluent society by means of transforming the environment and by extending their global, economic, cultural and political reach, the fact remains, that many citizens of North America are not wealth by any stretch of the imagination. The same can also be said about Latin America. The affluence has spread so unevenly, particularly in the United States, that many of the previously middle class have lost their homes and many are now living in tent cities. Recent college graduates are finding it very difficult to obtain employment in their chosen field. Many people have been unemployed long enough that their unemployment benefits have run out. These people are considered to be not actively seeking employment – this is hardly a fair opinion to form. Much of this can be accounted to work being outsourced, mainly to places like Mexico, or even as far as India. â€Å"Multinational corporations are often accused of social injustice, unfair working conditions (including slave labor wages and poor living and working conditions), as well as a lack of concern for the environment, mismanagement of natural resources, and ecological damage. † http://www. manufacturing. net/articles/2010/06/the-pros-and-cons-of-globalization. However, there are some benefits of globalization. Some people argue that money is now able to flow freely across boundaries that were once limited. An article found in Forbes Magazine explained how Sony could sell a Playstation game console or TV just as easily in the United States as Tokyo. The same goes for Apple with its iPhones and other tech toys. (http://www. forbes.com/sites/panosmourdoukoutas/2011/09/10/the-good-the-bad-and-the-ugly-side-of-globalization/). The textbook points out how uneven development is in Latin America. Frustrated workers, whether highly skilled or low skilled look to emigration as their only hope. Migrants frequently relocate to the United States, Europe and Japan looking for work. Remittances are sent back to their native countries, which results in billions of dollars annually directed to Latin America.

Transient Over Voltages Analysis In Power System Engineering Essay

Transient Over Voltages Analysis In Power System Engineering Essay Transient over-voltage is one of main causes for unscheduled interruption in power transmission and distribution systems including a smart grid. A surge over-voltage due to lightning and switching operation results in damages in an electrical power system and often leads to power outages. Predictive calculations of over-voltages generated by the lightning and the switching operation in the transmission and distribution systems are most essential for an economical insulation design and a reliable operation of the transmission and distribution systems. The transient over-voltage can be high frequency, medium frequency or low frequency. The transient over-voltage is dangerous to both lines as well as the connected equipment and may cause damage to the equipment. This project analyzes the transient at the load after switching. This project will discuss about analyzing a transient over-voltages which is the cause and the effect of the transient over-voltages. The method to solve this tran sient over-voltages also been discussed in this project. The PSCAD simulation is used for the transient analysis in this project to design the power system circuits. Problem Statement Voltage transient in Electric Power System appear several disturbances, sometimes very dangerous for the electrical equipment life, for the environment and for the human life. Switching transient phenomena produce in Power Systems over-voltages, over-currents and electrical fields, which havent to neglect. Thus was modeling and simulated the switching transient phenomena, consequently the electric fields and the possible negative influence about electrical equipment, environment and human life. Voltage transient in power system are cause by switching operation, lightning and faults in the system. The over-voltages can be dangerous to both the lines as well as the connected equipment and may cause damage to the equipment. Purpose of this project is to analyze the transient over-voltages at the load and to identify the method to reduce the effect of transient over-voltages. 1.2 Project Objective The objective of this project is as follows: Identify the effect and the cause of transient over-voltages and also the method to solving transient over-voltages. Simulate the transient over-voltages at the load after switching and design the power system circuits by using PSCAD simulation. Analyze the result after switching and after use pre-insertion resistor. 1.3 Project Scope In order to achieve the objective of this project, there are several scopes had been outlined as follows: Analysis on the distribution system. Generating the transient over-voltages waveform by using PSCAD simulation. The analysis is just focusing into transient over-voltages that occur because of the switching capacitor. Chapter 2 2.0 Literature Review 2.1 Introduction Voltage transients in power systems are caused by switching actions, lightning and faults in the system. Different phenomena create different types of transients. Oscillatory transients are caused mainly by switching phenomena in the network. The most common switching action is capacitor bank switching. The most severe transients are caused by capacitor energizing while capacitor de-energizing only causes a minor transient. Oscillatory transients are characterized by duration, magnitude and spectral content. There are subclasses of oscillatory transients depending on the dominant frequency. In this project it will more focus on switching devices. 2.2 Power System Electric power system is a very important part of the infrastructure of modern society. The power system today is very complex interconnected network. Electric power system is the system that can transform and change the form of the energy into electrical energy and transmit it to consumer. Technology today still cannot store the electricity that has been produced. The electrical energy only produce when needed or it will use after it is produced. As the effect, the management on the electricity becomes hard and difficult. The power system may be subdivided into the four major subsystems which are Generation subsystem, Transmission subsystem, Distribution subsystem and utilize subsystem. Figure 2.1 shows the power system that divided into generation, transmission and distribution. Figure 2.1: The Electric Power System 2.2.1 Generation Subsystem There are two major components in the generation system which is generators and transformers. For generators, an essential component of power systems is the three phase alternating current, ac, generator known as synchronous generator or alternator [1]. The source of the mechanical power, commonly known as the prime mover, may be hydraulic turbines, steam turbines whose energy comes from the burning of coal, gas and nuclear fuel, gas turbines, or occasionally internal combustion engines burning oil [1]. Some alternate sources used are solar power, geothermal power, wind power, tidal power and biomass. The power transformer transfer power with very high efficiency from one level of voltage to another level [1]. The transformer is been used to step up or step down the voltage. Insulation requirements and other practical design problems limit the generated voltage to low value, usually 30 kV. The step up is used for transmission of power. At the receiving end of the transmission lines, step down transformers are used to reduce the voltage to suitable values for distribution or utilization. The electricity in an electric power system may undergo four or five transformations between generator and consumers [1]. 2.2.2 Transmission Subsystem An overhead transmission network transfer electric power from generating units to the distribution system which ultimately supplies the load. It also interconnects neighboring utilities which allow the economic dispatch of power within regions during normal conditions, and the transfer of power between regions during emergencies. The network that interconnected between the utilities and load is called system grid [2]. The transmission line can be categorized into two categories which are high voltage transmission line and sub transmission line system. The difference between these two systems is in the voltage where for the high voltage, the level for transmission line voltage can reach 500kV and for sub transmission are in between 69kV to 138kV. All the transmission will be terminated at the substation [1]. 2.2.3 Distribution Subsystem The distribution system connects the distribution substations to the consumers service-entrance equipment. The voltage for this type of system has been reduced by using step down transformer from 66 kV to 22 kV and below. The secondary distribution network reduces the voltages for utilization by commercial and residential consumers. Lines and cables not exceeding a few hundred feet in length then deliver power to the individual consumers. The secondary distribution serves most of the customers at levels of 240 V for single phase and 415 V for three phases. Distribution systems are both overhead and underground. The growth of underground distribution has been extremely rapid and as much as 70 percent of new residential construction is via underground systems [1]. 2.2.4 Utilization Subsystem The utilities system or power system loads are divided into three main categories which are industrial, commercial and residential. Industrial loads are composite loads and induction motors form a high proportion of these loads [1]. These composite loads are functions of voltage and frequency and form a major part of the system load [1]. On the other hand, commercial and residential loads consist largely of lighting, heating, air conditioning and cooking [1]. These loads are independent of frequency and consume negligibly small reactive power [1]. The load varies throughout the day and power must be available to consumers on demand. The daily-load curve of a utility is a composite of demand made by various classes of users. The greatest value of load during 24 hour period is called the peak or maximum demand [1]. 2.3 Transient Over-voltages Transient is a sudden increase in current or voltage in a circuit that can damage sensitive components and instruments. Transient overvoltages are a voltage peak with a maximum duration of less than one millisecond. It can be high, medium, or low frequency. Transient overvoltages on power system are due to various causes and can be classified into two main categories, external and internal overvoltages [3]. Natural overvoltages on low voltage networks are caused by direct lightning strikes. Lightning is an external overvoltage. The high level of energy contained in a direct lightning strike on a lightning conductor or an overhead low voltage line leads to considerable damage of the installation. The overvoltages can be over 20 times the nominal voltage. Operating or switching overvoltages linked to a networks equipment create overvoltages of a lower level 3 to 5 times the nominal voltage but occur much more frequently, thus causing premature ageing of the equipment. Switching overvol tages is an internal overvoltage. Transient overvoltages are generally oscillatory and take the form of a damped sinusoid. The frequency of these overvoltages may vary from a few hundred Hz to a few kHz and it is governed by the inherent capacitances and inductances of the circuit. 2.2 Switching Capacitor Equipment containing electronic switching components is also likely to generate electrical disturbances comparable to over-voltages. The consequences of which on sensitive equipment, albeit not visible, are no less detrimental: premature ageing and unpredictable or fleeting breakdowns. Operating over-voltages are produced when reactive or capacitive equipment is switched on and off. Furthermore, interrupting factory production, lighting or transformers can generate over-voltages which will themselves cause greater damage to nearby electrical equipment. In general, these over-voltages are caused by transient phenomena which appear when the state of the network is changed by switching operation or fault condition. Example of these over-voltages is switching on and off equipment, such as switching of high voltage reactors and switching of a transformer at no load. The time duration of the switching over-voltages is longer than lightning. This overvoltage is most disastrous to the power system equipments because it happen many time than lightning. Closing, opening, disconnection and re-striking in a power system circuit result in over-voltages six times than the normal voltage. Shunt capacitors banks are common devices used in power system for reactive power compensation, voltage regulation and power factor correction. These capacitors are implemented in the system in order to control system voltage, increase power transfer capability, reduce equipment loading, and reduce energy costs by improving power factor of the system. However, energizing these shunt capacitors produces a transient oscillation in the power systems. Due to the fact that the operation of switching shunt capacitors happens frequently, shunt capacitor switching is regarded as the main source of generating transient voltages on many utility systems. These transients can cause damages on both utility systems and customer systems, depending on the system parameters such as switched shunt capacitor size, transformer size, and the type of customer loads connected to the system. Transient frequencies due to utility distribution capacitor switching usually fall in the range 300 Hz to 1000 Hz. Transient over-voltages which result are usually not of concern to the utility, since peak magnitudes are just below the level in which utility surge protection, such as arresters, begins to operate. However, because of the relatively low frequency, these transients will pass through step-down transformers to customer loads. Secondary over-voltages can c ause voltage magnification or nuisance tripping of adjustable-speed drives. Figure 2.2 show the example of single line diagram of the power system using shunt capacitor. Figure 2.3 show the transient voltage at the switched shunt capacitor. This is the example of the transient in the voltage waveform. Figure 2.4 show the transient voltage at the low voltage capacitor that has been magnetized. Figure 2.2: Example of Single Line Diagram of the Power System Using Shunt Capacitor Figure 2.3: Transient Voltages at the Switched Shunt Capacitor Figure 2.4: Magnified Transient Voltage at the Low Voltage Capacitor 2.3 Pre-Insertion Resistor There are several techniques to mitigation the switching transient in the distribution circuit and one of the techniques that use in this project is pre-insertion resistor. A pre-insertion resistor provides a means for reducing the transient voltages associated with the energization of a shunt capacitor bank. The resistors were connected in series with the controlled capacitor bank to damp the transient inrush current. The resistor is bypassed shortly after the initial transient dissipates, thereby producing second transient event. An additional switch is use to bypass this resistor. The performance of pre-insertion resistor is evaluated using both the insertion and bypass transient magnitudes, as well as the capability to dissipate the energy associated with the event and repeat the event on a regular basis. The size for this resistor was calculated from equation 2.1 and 2.2. The optimum resistor value for controlling capacitor energizing transients depends primarily on the capacito r size and the source strength. The value of the resistor is approximately equal to the surge impedance, Zo, from equation 2.3. R = (2.1) Z = (2.2) Roptimum ≈ Z (2.3) Chapter 3 3.0 Methodology 3.1 Introduction This chapter describes about the step that needed in this project. Figure 3.1 show the block diagram of analysis and figure 3.2 show the flowchart of the process analysis. This block diagram shows the step from the first step of the project which is design the circuit to the final step which is result and analysis. Design Circuit Placing Input and Output Devices Running Simulation Result and Analysis Figure 3.1: The Block Diagram of Analysis In order to get the result from the Power System Computer Aided Design (PSCAD), the user should follow the step as follow in the Figure 3.2. Figure 3.2: Flowchart of Process Analysis 3.2 Design Circuit This is the process to build up the diagram of the circuit for the analysis. The user need to choose and selecting component from master library and put it in the main page where the user will construct the circuit. There are many components with a different type of setting. The user only need to double click on the component to edit or changes the setting and parameter. Project development consists of two parts electronic and software designs. Figure 3.2 show the three phase source that use in this project. This source impedance is type R because resistor connected series with the source. The source in this project is being controlled through fixed parameter. Figure 3.2: Three Phase Source Figure 3.3 show the three phase transformer that use in this project. The type of the transformer is a three phase and two winding transformer. The transformer is connected in star delta connection. Other characteristic for the transformer in this project is the transformer use to step up the voltage. Figure 3.3: Three Phase Transformer 3.3 Placing Input and Output Devices This process is used to get the measurement, signal and waveform of the graph in selecting part or component. The output device must be placed at the point of measurement before plotting can be done on the drawing space. Without this device, the PSCAD cannot create the plotting and the result cannot be obtained. After the circuit had already been executed and there is no error, the output from the circuit or diagram will be obtained. Figure 3.4 shows some of the output and input devices that used in this project. Figure 3.4: The input and output devices 3.4 Running Simulation After complete all the circuit design and placing input and output device, the user need to run the circuit to get the result. To run the simulation the user only need to click on the run button in the main toolbar. Figure 3.5 show the location of run button at the main toolbar. The run toolbar have a green color. When this button is pressed, PSCAD will go through several stages of processing the circuit before starting the EMTDC simulation. Figure 3.5: The run button at main toolbar During the run time, the work will be compiling by the PSCAD. The result or output only will produce if there is no error in the setting of the circuit in the drawing or all connection is connected. If there is an error, the warning will appear at output space. Once the program is no error and running, the graph and also the measurement will be produce depending on the selected node. The user also able to pause and zoomed the graph. 3.5 Graph Calculation The graph give the certain value to calculated the overshoot, resonant frequency and also the curve can be identified as an overdamped, underdamped or critical damped. Equation 3.1 is use to calculate the overshoot. Equation 3.2 is uses to calculate the resonant frequency, ωo. % OS = -100 (3.1) ωo = (3.2) The curve is overdamped if ÃŽ ± is bigger than ωo, underdamped if ÃŽ ± is smaller than ωo and critically damped if ÃŽ ± is equal to ωo. Equation 3.3 to 3.8 shows the step to get a value of ÃŽ ±. Figure 3.6 shows the example of the series RLC circuit. Figure 3.6: The Series RLC Circuit Equation 3.3 is equation for series RLC circuit. Equation 3.4 and 3.5 is a root for quadratic equation for 3.3. ( 3.3) (3.4) (3.5) The root for equation 3.4 and 3.5 can be express to equation 3.6 and 3.7. (3.6) (3.7) From equation 3.4 and 3.6, the value for damping factor, ÃŽ ±, calculated as equation 3.8. (3.8) Chapter 4 4.0 Expected Result The transient over-voltages that occur at the load during capacitor switching will be discuss base on result at all buses in the circuit that will be design before doing the simulations. The discussion is about the voltage waveform when transient over-voltages occur and voltage waveform when the simulations using pre-insertion resistors to reduce transient over-voltages. The results of waveform at all buses that will be obtain from PSCAD simulation will be discuss in term of peak voltage, overshoot and weather that waveform is overdamped, underdamped or critically damped.

Figure 4.2 show the voltage waveform that will get at all buses after simulate it using pre-insertion resistor. The transient will be reduce after doing the simulation using pre-insertion resistor. Figure 4.1: Transient Over-voltage Waveform at Buses. Figure 4.2: Voltage Waveform at Buses after Pre-Insertion Resistor. Chapter 5 5.0 Conclusion In PSM 1 all the literature review regarding this project are been studied so at the end of PSM 1 it can be summarized that the objectives of the project will be fulfilled in the next PSM 2, which is to design the circuit, running the PSCAD simulations and analyze the result that obtain from the PSCAD simulations in term of peak voltage, overshoot and weather that waveform is overdamped, underdamped or critically damped. This progress will need more commitment and efforts. In conjunction to achieve that, scope and objectives of this project will be the guideline.

The Articles of Confederation :: American America History

The Articles of Confederation During the Revolutionary period, the United States and Britain had many conflicts. Between 1763-1776, there were issues among these two countries. Between 1780-1789, there were issues about the federal government and the states under the Articles of Confederation. Two of these issues happened to be the foreign affairs between Britain and the United States, and the economy of the federal government. Subsequently following the French and Indian War, which happened to be where the British fought for the American colonies, Britain was in great need to pay its debts. Holding the war against the colonies, Britain decided to tax the colonies to pay for their large debt. Not being treated as members of the British Empire, the colonists were angered at the thought of being a source for Britain?s revenue. Acting in protest to what the colonies considered to be unjust laws, the colonists resisted attempts to be taxed, claiming as long as they weren?t allowed fair representation in the English Parliament, they would not pay. In 1650, a series of laws called the Navigation Acts were issued for the American colonies; although they did not come into full effect until after the French and Indian War. These laws prohibited the trade of certain items, which made it difficult for merchants who relied on French, Spanish, and other foreign countries for business. These restrictions angered the merchants, seeing as they were not allowed to make specific products in the colonies any longer, Heavy tariffs made trade nearly impossible and led the colonists to believe Britain was purposely doing this to hurt the economy of the colonists. England enacted laws to create trouble with trade between the colonies and other countries. In 1764, the Sugar Act was issued; this law taxed sugar, textiles, and other goods. One year following this the Stamp Act was put into effect, taxing all legal documents, newspapers, and playing cards. Shortly after, the Townshend Acts came into place, taxing lead, glass, iron, and manufactured goods within the colonies. The colonists became infuriated at these new laws stating they were too heavy and were levied without their direct consent. Britain thought it only necessary to place troops in America for the safety and protection of their colonies. They thought since they were doing such a great favor for the colonies, that it was only fair, and that the colonists would not mind providing the supplies needed to tend and care for the troops sent there.

Perceptions of the Cold War Essay -- Cold War Interviews

This is an interview project with the goal of discovering how people understand the Cold War. In this essay, I will analyze how people understand the Cold War today. I will explain to what extent their definition or understanding of the Cold War differs from the definition provided. I will explain why the respondents’ understanding of the Cold War is different from the way the Cold War is defined in this course or explain why the respondents’ definition is similar to the way the Cold War is defined in this course. This course defines the Cold War as the geopolitical tensions, and proxy wars fought between the United States and the Soviet Union. The Soviet Union and the United States repeatedly annoyed each other through political scheming, military alliances, spying, publicity, arms accumulation, financial aid, and proxy wars between other nations, but did not fight directly during the Cold War (John F. Kennedy Presidential Library and Museum, n.d.). The Cold War is a title that was given to the communication that established for the most part between the United States and the Soviet Union after World War II (Trueman, 2013). The Cold War began in 1945 and ended in 1991 (History Rocket, 2012). The Cold War began because the communist nations did not permit fundamental human freedom, so the United States had hostility against the communists (History Rocket, 2012). The increase in weapons of mass destruction had many worried. The Cold War defined American political view and molded foreign policy (Naranjo, 2014). Mary Wheatly a registered nurse born in 1968 was the first person interviewed.

Psychology of Negotiation Essay

Abstract Every day we may negotiate with people many times without being aware of it. The social reality is actually a big negotiating table, and we are playing a variety of negotiators in different situations. In the community, you might have conflict with others, and in order to solve these conflicts, you need to negotiate. Negotiation, to some extent, is a psychological game. So if we have the knowledge of it, we can make a good deal. This paper talked about the significance of studying psychological of negotiation, people’s different needs, motives, and temperaments in negotiation which could help negotiators to make successful negotiations with knowing them. Also, how to deal with the emotion problems people may have during negotiations. Negotiation is an indispensable part of our daily life, because it happens in our lives almost every day. Once we get rid of negotiation, we’re going to lose many of our rights, and right then it’s hard to express our true thoughts, and even if there are conflicts of interests, we can not protect our own benefits. In essence, the direct reason that lead to negotiation is the demands of negotiating parties, or the demand of the organization that one represents, can not be ignored when the other party meet their demand. Therefore, the main purpose of two parties participating in a negotiation, are not only to pursue their own needs, but also to find an acceptable solution for both parties through the exchanging of views and consulting. Former U.S. President John F. Kennedy had a famous saying in his inaugural speech, â€Å"let us never negotiate out of fear, but let us never fear to negotiate.† On some level, negotiation is a mental game. We can learn from psychology that people’s needs, motives and behavior are closely related. What in a person’s mind affect his behavior, so psychology of business negotiation has important impact on the behavior in negotiation. Using psychological knowledge in negotiations will help people win the game. Psychology of business negotiation refers to various mental activities of negotiators in negotiations. It is a subjective reflection of negotiators towards variety of situations, conditions and other objective facts in negotiation. For example, when negotiator first meets the opponent in negotiation, and if the opponent is polite, sincere, and easy to communicate, the negotiator will has a good impression toward the other, and  he will be more confident and hopeful to make the deal. Being familiar with psychology in negotiation, will help negotiators handle a variety of complex negotiation problem flexibly and efficiently. I t is also significant for negotiators to develop excellent psychological quality, maintain a good attitude, judge the opponent’s psychological states and motives correctly, and predict and guide opponent’s behavior. The negotiator’s self-confidence in making negotiation successful, the sincerity towards negotiation, the management and control of emotion in negotiation, and the prevention and handling with obstacles are indispensable psychological qualities that guarantee successful negotiation. Therefore, negotiator should develop and improve their own excellent psychological qualities, and abandon the bad psychological behavior. The secret of negotiation is to grasp each other’s needs. Demand is the core of the negotiation. Needs and meeting the needs is the common basis for negotiation. For example, I have my own needs and the ability to satisfy others, and others have their own needs and the abilities to satisfy my needs. Therefore, we can satisfy each other, and this becomes the common basis of negotiation. Demand is a subjective state when one lacks something, which is a reflection of the needs of the people of a certain objective things, and that the objective needs of nature and society reflected in the brain. The demands in negotiation have several types: 1. Physiological needs: the original, basic, necessary needs for human survival, such as breathing, eating, drinking, sleeping, etc. No matter how tight, intense the negotiation is, the personnel participating in the negotiation must ensure to meet the physiological needs. The better we set up the dining, resting and entertainment in the negotiation, the higher the efficiency of negotiation is going to be. On the contrary, if people’s physiological needs can be satisfied, the negotiation can be directly affected. 2. Security needs: mainly refers to a person’s sense of security, stability and order. Business negotiators have strong security needs. To consider the credit security, the negotiators usually like to deal with old customers, and they feel scruples in dealing with new customers. In business negotiations, negotiators are generally concerned about the risks in transactions. For negotiators that are more sensitive, they would worry the condition of the main qualif ications, property, funds and reputation of the opponents. Sometimes they prefer to give up the attractive large  transactions, to select more solid small transactions or even give up the transaction. 3. Social needs: mainly represent the needs to seek and improve interpersonal relationship. Business negotiators have social needs. Negotiations are typical social activities. In a society that economy and culture are well-developed, people’s activities show their social needs. Social needs is a delicate and subtle needs, and it is related to one’s personality, psychological characteristics, experiences, cultural upbringing, habits, and religious beliefs. 4. Esteem needs: including being respected and self-esteem. To embody it is to hope one himself or herself having ability and achievements, be qualified for a job, be eager to get the appreciation of others, fame and glory. This kind of psychological needs showing in negotiation is that some people like to show their identity and authority, or others like to listen to people’s compliments and so on. The person who has a strong esteem needs might has aggressive and hostile behavior, or does not like to cooperate because of the working of psychological defense when his or her does not feel to be respected or the pride was hurt, and this will bring a big obstacle to negotiation. U.S. Oil Consortium would like to buy natural gas in Mexico with low price, so they had a negotiation about the price. The U.S. energy secretary believed that there was no potential buyer and Mexico would lower the price eventually since it was just a negotiation about money. However, the Mexicans needs w ere not only just selling natural gas at a good price, but also being respected and equal. And the Americans’ behavior looked like a bully for Mexicans, so the Mexico government decided not to burn the natural gas to the ground instead of selling to the U.S.. Therefore, any chance of making an agreement in politics is impossible. The case shows us that people may withdraw from the negotiation or give up the original plan of conducting transactions in order to safeguard the prestige and dignity. 5. Self-actualization needs: Self-actualization is to make one’s potential getting realistic. When you make the efforts to let others give you the special privilege, your satisfaction may reach a peak, and this is the representation of self-actualization. In actual negotiations, a strategy that people always use is to give the lowest offer, which is using this psychological phenomenon. â€Å"This is our best price†, is a typical example of using the psychology of pursuing self-actualization. In many circumstances,  negotiators are not on behalf of themselves, but on behalf of the organization to participate the negotiations. While they are trying to meet the individual needs, they also have to consider about the needs of the group or the organization. As a negotiator representing an organization, from the view of ethics, the needs of the organization should be put in the first place. One should try to satisfy the needs of group or organization through hard work. Where there is a need, there is a motive. Motive is the internal power to promote people to meet the needs. In other words, it is an internal driving force to promote people to do activities. The motive of negotiation is the driver to promote negotiators to make a negotiation to meet their needs. â€Å"Social motives determine negotiators’ preferences for resource allocation, that is, wheth er negotiators’ focus on maximizing collective or personal outcomes.† (Olekalns, M. & Smith, P.L., Jan, 2012) There are four-type motives of negotiation. 1. Economy-type motive: This kind of motive refers to that the negotiators are very sensitive to the economic factors such as transaction price and they take economic interests seriously. The negotiating behavior is mainly driven by economic interests. 2. Impulse-type motive: This means that the negotiators are impulsive in decision-making in negotiations, and their negotiating behaviors are induced by their emotions like irritation. 3. Misgiving-type motive: This means that the negotiators’ behavior is affected by suspicions and worries to cause the discreet negotiating behavior. 4. Adventurous-type motive: This means the negotiators like to take risks to pursue a more perfect outcome. Their negotiating behaviors are triggered by risks. When people have some kinds of needs but not be satisfied, they will have a nervous state of mind, and when they encounter the goal that can meet their needs, the nervous state of mind will turn into motives, to promote people engage in certain activities and achieve the goal. As a negotiator, one should have the insight to know the other party’s needs and motives, and adjust the negotiating strategy in order to have the control of negotiation. In business negotiation, the negotiators’ characteristics and personalities also have important impact on their negotiating behavior. â€Å"Personality clashes created via ‘posturing’ and ‘saving face’ can block progress in  negotiations.† (Hoffman, E., Dec, 2012) Personality affects the style, efficiency and effectiveness of negotiation. 2500 years ago, the ancient reek physician Hippocrates believed that the human body was filled with four basic substances, called humors. The four humors were black bile, yellow bile, phlegm, and blood. (Wikipedia, the free encyclopedia) The four humors form the four types of temperament. The negotiating personality of each temperament is power-type, convince-type, execute-type and misgiving-type. 1. Power-type: Power-type negotiator is a competitive opponent in negotiation. If you obey him, he will â€Å"eat you up†, and if you resist him, the negotiation will come to a dead end or be terminated. The best way to deal with this kind of people is to overcome hardness with softness. When they are furious or try to force one to make a deal, do not rush to refute or give it back, one should try his or her best to avoid direct conflict face to face, and be patient to listen. When the conflict is inevitable, one shall not surrender. One should use the facts to prove they were wrong, and fight back calmly. When you speak for the truth, they will be cool and may have respect and admire for you. It’s good to satisfy their self-esteem, stimulate challenge, make obstacles and induce risks to make the negotiation succeed. 2. Convince-type: The most common negotiators are convince-type in negotiation. They are shrewd, cautious, affable in appearance, and full of charm. They are good at discover and cater the opponents’ interest, and convince people gradually. Under many circumstances, even if they do not agree with other parties’ proposals, they would not refuse directly, and they always try to convince the other parties or illustrate their reason why they do not accept. The best way to deal with this kind of people is to persuade them repeatedly, because they like to hear from others and love to take advices. As long as your products fit their needs, and the price is reasonable, they will take it eventually. In addition, they are concerned about relationships, and they do not like making conflict, so repeated persuasion will be very effective. It’ll be good to make small conflicts and prepare some compliments and many questions in details to make the deal quick in negotiation. â€Å"It’s a fact of life that dealing with an intelligent well-balanced person will be the toughest negotiation, but it also offers the prospect of creating a genuine â€Å"win-win† agreement in the shortest possible time.† (Palmer, A., 2006) 3. Execute-type: The negotiators have  this kind of temperament can not work independently in negotiations. They like to play by the rules and implement with the plan in advance toward superiors’ orders and instructions. They usually do not have their own ideas and insights, and they lack of the ability to think and imagine. They often have poor decision-making and adapting ability. Trying to keep the status quo as it is is their greatest wish. The most effective way to deal with this kind of people is to be calm, patient and try to use more detailed information and precedents. They like safe and orderly negotiation. As far as possible to negotiate as planed when they are your opponents. They are concerned about the details, so try to show more information to support your idea and gain their trust. It’s good to divide negotiation to some periods with specific goals, and try to speed up the process of negotiation. 4. Misgiving-type: This kind of opponents have strong security needs and risk awareness. They always have scruples when dealing with new customers. They are worried about having disadvantage and being cheated, so they are anxious for gains and losses, sensitive, suspicious, defensive, close-minded and critical. They like to spy on their opponents’ minds, so it is advised to take a moderate negotiation with them. The effective way to deal with them is to provide more witnesses, evidences and other proofs. This kind of opponents is very suspicious. Whatever you say, they want to confirm to be assured. If you fool them with one answer, it seems to be impossible to gain their trust again. You have to be honest and passionate with these people. It is good to be cautious with your behavior, give them time to consider, make small conflict when they are doubted with the apparent facts. Therefore, when we observe and understand the opponents’ types, we can accept their shortcomings and deficiencies calmly, and take effective measures according to their psychological characteristics to control the direction of negotiations. Although we know the types of people we are going to deal with in negotiations, everyone has emotions that may blow off the negotiations. Business negotiations are complex and variable, and both parties’ emotions may fluctuate with the process of negotiation. Being too emotional is not good for negotiation. â€Å"The most successful negotiators are able to rise above the emotional aspects separating the people from the tasks.† (The Psychology of Negotiation) We have to make effective regulations on emotions of each party, we can make the negotiations proceed  in the way we expected. Negotiators should have self-control of their emotions. Whether the negotiations are going well or bad for their own party, they should be ratio nal rather than being manipulated by the opponents. â€Å"Mueller and Curhan found that negotiators with emotionally intelligent opponents were more satisfied with the negotiation outcome, liked their partners better, and were more willing to engage in future negotiations with the same partner than those negotiators with opponents who did not understand emotion as well.† (Gelafand, M.J., Fulmer, A. & Severance, L.) Sometimes people can use good-cop, bad-cop strategy to control the opponents in order to make the deal. U.S. tycoons Howard Hughes once wanted to buy a fleet of aircraft. Because he wanted to purchase a huge amount, it was a very good deal for the manufacturers. But Hughes stated that he wanted to write down his specific requirements on the agreement which were 34 clauses totally, and the manufacturer had to fulfill 11 clauses of the requirements. Hughes’s attitude in the negotiation is domineering, and hard-lined. He refused to consider about others, which aroused the anger of the manufacturer. At last, the m anufacturer announced that they would not have any negotiation with him. So later, Hughes sent his private representative to come forward to negotiate, and finally they made the deal with fulfilling 30 clauses of the requirements. But how did the representative win the negotiation? The answer is simple. Every time they had a conflict, the representative would ask, â€Å"Who do you prefer to settle this problem with, me or Howard Hughes?† So they eventually made it work by playing â€Å"good-cop and bad-cop†. Negotiation is an activity we may have to participate almost every day. Where there is a conflict, there will be a negotiation or compromise. However, we could use psychology to analysis people’s minds and behavior in negotiation to help us make a successful negotiation. Reference Hoffman, E.(Dec.2012).
