Theories of leadership:

Theories of leadership: Introduction â€Å"The term leadership is a word taken from the common vocabulary and incorporated into the technical vocabulary of a scientific discipline without being precisely redefined. As consequences, it carries extraneous connotations that create ambiguity of meaning (Janda, 1960). Additional confusion is caused by the use of other imprecise terms such as power, authority, management, administration, control and supervision to describe similar phenomena. An observation by Bennis (1959, p. 259) is as true today as when he made it many years ago: Always, it seems, the concept of leadership eludes us or turns up in another form to taunt us again with its slipperiness and complexity. So we have invented an endless proliferation of terms to deal with it. and still the concept is not sufficiently defined.† â€Å"Most definition of leadership reflect the assumption that involves a process whereby intentional influences is exerted over other people to guide, structure, and facilitate acti vities and relationships in a group or organisation. The numerous definitions of leadership appear to have little else in common. They differ in many respects, including who exerts influence, the intended purpose of the influence, the manner in which influence is exerted, and the outcome of the influence attempt. The differences are not just t a case of scholarly nit picking; they reflect deep disagreement about identification of leaders and leadership processes.†(Gary Yukl, 2010) Theories of leadership: Douglas McGregor described Theory X and Theory Y in his book, The Human Side of Enterprise. Theory X and Theory Y each represent different ways in which leaders view employees. Theory X managers believe that employees are motivated mainly by money, are lazy, uncooperative, and have poor work habits. Theory Y managers believe that subordinates work hard, are cooperative, and have positive attitudes. Theory X is the traditional view of direction and control by managers. It is the nature of average human being who dislikes doing work and will avoid if he or she can. Because of this human characteristic of dislike of work, most people must be controlled, directed, and threatened with punishment to get them to put forth adequate effort toward the achievement of organizational objectives. The average human being prefers to be directed, wishes to avoid responsibility, and has relatively little ambition, wants security above all. Theory Y is the view that individual and organizational goals can be integrated. The expenditures of physical and mental effort in work are as natural as play or rest. External control and the threat of punishment are not the only means for bringing out effort toward organizational objectives. Commitment to objectives is a function of the rewards associated with their achievement. The average human being learns, under proper conditions, not only to accept but also to seek responsibility. The capacity to exercise a relatively high degree of imagination, ingenuity, and creativity in the solution of organizational problems in widely, not narrowly, distributed in the population. Under the condition of modern industrial life, the intellectual potentialities of the average human being are only partially utilized. Fred E. Fiedlers contingency theory postulates that there is no best way for managers to lead. Situations will create different leadership style requirements for a manager. The solution to a managerial situation is contingent on the factors that impose on the situation. For example, in a highly routinized (mechanistic) environment where repetitive tasks are the norm, a certain leadership style may result in the best performance. The same leadership style may not work in a very dynamic environment. Fiedler looked at three situations that could define the condition of a managerial task: Leader member relations: Compatibility between the manager and the employees? The task structure: Is the job highly structured, fairly unstructured, or somewhere in between? Position power: How much authority does the manager possess? Managers were rated as to whether they were relationship oriented or task oriented. Task oriented managers tend to do better in situations that have good leader-member relationships, structured tasks, and either weak or strong position power. They do well when the task is unstructured but position power is strong. Also, they did well at the other end of the spectrum when the leader member relations were moderate to poor and the task was unstructured. Relationship oriented managers do better in all other situations. Thus, a given situation might call for a manager with a different style or a manager who could take on a different style for a different situation. Another aspect of the contingency model theory is that the leader-member relations, task structure, and position power dictate a leaders situational control. Leader-member relations are the amount of loyalty, dependability, and support that the leader receives from employees. It is a measure of how the manager perceives he or she and the group of employees are getting along together. In a favorable relationship the manager has a high task structure and is able to reward or punish employees without any problems. In an unfavorable relationship the task is usually unstructured and the leader possesses limited authority. Positioning power measures the amount of power or authority the manager perceives the organization has given him or her for the purpose of directing, rewarding, and punishing subordinates. Positioning power of managers depends on the taking away (favorable) or increasing (unfavorable) the decision-making power of employees. The task-motivated style leader experiences pride and satisfaction in the task accomplishment for the organization, while the relationship-motivated style seeks to build interpersonal relations and extend extra help for the team development in the organization. There is no good or bad leadership style. Each person has his or her own preferences for leadership. Task-motivated leaders are at their best when the group performs successfully such as achieving a new sales record or outperforming the major competitor. Relationship-oriented leaders are at their best when greater customer satisfaction is gained and a positive company image is established. Hersey-Blanchard Situational Leadership The Hersey-Blanchard Situational Leadership theory is based on the amount of direction (task behaviour) and amount of socio-emotional support (relationship behaviour) a leader must provide given the situation and the level of maturity of the followers. Task behaviour is the extent to which the leader engages in spelling out the duties and responsibilities to an individual or group. In task behaviour the leader engages in one-way communication. Relationship behaviour is the extent to which the leader engages in two-way or multi-way communications. This includes listening, facilitating, and supportive behaviours. In relationship behaviour the leader engages in two-way communication by providing socio-emotional support. Maturity is the willingness and ability of a person to take responsibility for directing his or her own behaviour. People tend to have varying degrees of maturity, depending on the specific task, function, or objective that a leader is attempting to accomplish through th eir efforts. To determine the appropriate leadership style to use in a given situation, the leader must first determine the maturity level of the followers in relation to the specific task that the leader is attempting to accomplish through the effort of the followers. As the level of followers maturity increases, the leader should begin to reduce his or her task behavior and increase relationship behaviour until the followers reach a moderate level of maturity. As the followers begin to move into an above average level of maturity, the leader should decrease not only task behaviour but also relationship behaviour. Houses Path-Goal Model The path-goal theory developed by Robert House is based on the expectancy theory of motivation. The managers job is viewed as coaching or guiding workers to choose the best paths for reaching their goals. Best is judged by the accompanying achievement of organizational goals. It is based on the precepts of goal setting theory and argues that leaders will have to engage in different types of leadership behavior depending on the nature and demands of the particular situation. It is the leaders job to assist followers in attaining goals and to provide direction and support needed to ensure that their goals are compatible with the organizations. A leaders behaviour is acceptable to subordinates when viewed as a source of satisfaction and motivational when need satisfaction is contingent on performance, and the leader facilitates, coaches and rewards effective performance. Path goal theory identifies achievement-oriented, directive, participative and supportive leadership styles. In achievement-oriented leadership, the leader sets challenging goals for followers, expects them to perform at their highest level, and shows confidence in their ability to meet this expectation. This style is appropriate when the follower suffers from lack of job challenge. In directive leadership, the leader lets followers know what is expected of them and tells them how to perform their tasks. This style is appropriate when the follower has an ambiguous job. Participative leadership involves leaders consulting with followers and asking for their suggestions before making a decision. This style is appropriate when the follower is using improper pr ocedures or is making poor decisions. In supportive leadership, the leader is friendly and approachable. He or she shows concern for followers psychological well being. This style is appropriate when the followers lack confidence. Path-Goal theory assumes that leaders are flexible and that they can change their style, as situations require. Effective leaders clarify the path to help their followers achieve their goals and make the journey easier by reducing roadblocks and pitfalls. Research demonstrates that employee performance and satisfaction are positively influenced when the leader compensates for the shortcomings in either the employee or the work setting. Leadership plays an important role in ones life. If one is a business owner he needs to be a leader in the field of your business. To be a successful leader, one must demonstrates some or all of the following characteristics: The ability to listen: Most leaders do too much talking but not enough listening. Feedbacks to a persons company services or products are important to that person as they demonstrate the customers needs. The ability to acknowledge and change: This is probably the hardest part to do. People often refuse to change. They believe their services or products are the best, which, theres nothing wrong with that. But when there are feedbacks coming from customers you have to listen, then acknowledge them and make changes to provide better customer service. The ability to form one-on-one relationships: People will need to be able to reach you. If you are just starting a business its especially important for you to be able to spend some time to get to know your customers, and/or employees. If you do that, over time, you will develop a strong trust between you and your customers. Successful people make sure they surround themselves with like-minded people. Im not saying millionaires should just ignore the poor. But you need to spend time to communicate with like-minded people. You cannot survive by yourself, and by interacting with others you can motivate others or give others a chance to motivate you. The ability to know yourself: It is very important to know what youre best at, and what your weaknesses are. A business is a team sport. Often one cannot handle all the aspects of a business and need to know when to seek for assistance. Successful people refuse to let other people dictate how they should do certain things. We are not living under someone elses shadow. We must take control and ownership of our lives and careers and never let go. The ability to communicate: Communication is really very important. Even if you are running a home online business and you use email as a communication channel. Down the road, you might want to do a video to promote your company. You might receive TV interviews. Its never too late to practice your presentation and communication skills. Successful people display high levels of optimism and confidence. They believe in themselves and they are not afraid of failures. They see every obstacle as a stepping-stone to their success. They turn challenges into motivators and become their advantages. People who are successful are the ones who are passionate at what they do. People who are successful are the ones who develop high levels of patience and dedication to see the results. http://ezinearticles.com/?Top-10-Characteristics-of-a-Successful-Leaderid=1552997 Characteristics of Successful and Effective Leadership It is not only inborn personality traits that are important but also styles and behaviours that a person learns. Strong autocratic leaders set their goals without considering the opinions of their followers, and then command their followers to execute their assigned tasks without question. Consultative leaders solicit the opinions and ideas of their followers in the goal-setting process but ultimately determine important goals and task assignments on their own. Democratic or participative leaders participate equally in the process with their followers and let the group make decisions. Extremely laid-back leaders, so called laissez-faire leaders, let the group take whatever action its members feel is necessary. A research team at the University of Michigan, inspired and led by Renis Likert, studied leadership for several years and identified two distinct styles, which they referred to as job-centered and employee-centered leadership styles. The job-centered leader closely supervises subordinates to make sure they perform their tasks following the specified procedures. This type of leader relies on reward, punishment, and legitimate power to influence the behaviour of followers. The employee-centered leader believes that creating a supportive work environment ultimately is the road to superior organizational performance. The employee-centered leader shows great concern about the employees emotional well-being, personal growth and development, and achievement. A leadership study group at Ohio State University, headed by Harris Fleishman, found similar contrasts in leadership style, which they referred to as initiating structure and consideration. The leadership style of initiating structure is similar to the job-centered leadership style, whereas consideration is similar to the employee-centered leadership style. It was the initial expectation of both research groups that a leader who could demonstrate both high initiating structure (job centered) and high consideration (employee centered) would be successful and effective in all circumstances. Many students of leadership today believe that there is no one best way to lead, believing instead that appropriate leadership styles vary depending on situations. Fred Fiedler (1967), for instance, believes that a task-oriented leadership style is appropriate when the situation is either extremely favorable or extremely unfavorable to the leader. A favorable situation exists when the relationship between the leader and followers is good, their tasks are well-defined, and the leader has strong power; when the opposite is true, an unfavorable situation exists. When the situation is moderately favorable, a people-oriented leadership style is appropriate. Some theorists suggest that situational factors—the type of task, nature of work groups, formal authority system, personality and maturity level of followers, experience, and ability of followers—are critical in determining the most effective leadership style. For instance, when followers are inexperienced and lack maturi ty and responsibility, the directive leadership style is effective; when followers are experienced and willing to take charge, supportive leadership is effective.

Discussion It is well known that a change in the temperature of a solution will result in the change of conductivity. An increase in temperature results in an increase in conductivity. The increase that is observed is as a result of a number of factors. Firstly, the increase in temperature can cause ionic compounds to split resulting in an increasing number of ions in the solution. So in this experiment the diffusivity of NaCl in H2O, the NaCl compound will break apart resulting in Na and Cl ions surrounded by H2O molecules. As the NaCl (in water it is classed as an electrolyte) dissolves (diffuses) charged ions (Na and Cl) are formed that can carry charge. Secondly, the increasing temperature of a solution can result in a lower viscosity. This in turn increases ion mobility throughout the H2O, which further increases the ability of the ions to carry the charge throughout the solution and therefore increases conductivity. These two factors highlight the significance that temperature plays in the diffusivity of a compound in a solution. Not including the variation of temperature would certainly have affected the final value. The conductivity of the stock solution was given as 189.6 mS at 22 °C. This value wasnt adjusted to a more accurate temperature at which the experiment was performed at which was approximately between 32-33 °C. The measured value from the calculation of may not be completely accurate. The majority of substances that dissolve in a solvent such as NaCl in water already have diffusion coefficients predetermined which allows one to compare the accuracy of the measurement against. Diffusion coefficients are measured at specific temperatures because of the fact that there value is temperature dependent. If the experiment was not carried out at the reference diffusion coefficients temperature then a temperature compensation method may be used, which was the case in this experiment, where the measured value was adjusted to the reference value. Compensation methods include both linear and non-linear methods to adjust the conductivity value attained with a %/ °C value. However these methods are not completely accurate and it is preferable that a conductivity measurement be taken at the same temperature as the reference value. This is particularly true where highly accurate measurements are required. In this experiment no variation in temperature was assumed. To incorporate a variation in temperature one could use a temperature compensation method but as Ive mentioned this isnt entirely accurate. These factors are only likely to have relatively minor inaccuracies. Comparing the two values there are several orders of magnitude of a difference. Several factors have influenced this including errors in the actual apparatus for measuring the conductivity in the diffusion cell as well as the errors that occurred during the experiment. It can be seen from the early measurements of conductivity that something went wrong with one or more of the apparatuses as erroneous results were produced.   From the 4th to the 5th measurement there is a large jump in conductivity. This large sudden variation in conductivity was caused by an air bubble blocking the conductivity meter. The air bubble present in the diffusion cell gave the false conductivity measurement. This resulted in an outlier in the conductivity versus time graph. A trendline was fitted to the graph to allow the slope to be calculated as the outliers present result in a non-linear graph. Despite this trendline this large variation certainly affected the final measured value. From the point of view of the apparatus it does certainly have some limitations.   The heating element is at one end of the device and so it doesnt give a consistent dispersion throughout the tank as the side of the tank nearest the element would be of a slightly higher temperature than the rest of the tank. It is difficult to say how much this would affect the diffusivity but it is something to consider. Conclusion A quantitative value for the diffusivity of NaCl in water was determined. The calculated measured value attained was compared against a reference value and a large discrepancy was observed between the two values. The reasons for the discrepancy from an experimental and theoretical point of view have being outlined in the discussion. References: Barron, J. and Ashton, C.

Importance of Marriage and Money in Austen’s Pride and Prejudice and Today Essay

During the days of Jane Austen, a financially stable marriage was crucial to many women. On the contrary, some of the women did not think marriage was mainly about money. These concepts reflect through some of Austen’s characters in her comic novel of manners, Pride and Prejudice. While writing this novel, Austen illustrates the way of life during her time period through her characters. The idea of marriage being financially crucial to some women is not as true today like it was during Austen’s time period. Women’s lives have changed considerably over the past years, making this idea not as common. Women today do not have problems in common with those of Austen’s characters. After reading Austen’s Pride and Prejudice, readers can compare the financial problems of women today to those of the women of Austen’s time, finding the difference between them the importance of money and marriage. The female characters in Austen’s novel go through great lengths to catch a husband. Unlike marriages today, many marriages in Austen’s time were not based off love, but security for the future. Most women wanted to marry wealthy men to insure their financial and social future: â€Å"In cases nine out of ten, a woman had better show more affection than she feels.† Charlotte Lucas makes this statement to Elizabeth during the beginning of the novel. This statement shows the feeling of most women during Austen’s time, which was that a women should show more affection towards a man than she actually felt in order to get him to propose to her. Women went through great lengths to fake emotions for a marriage proposal. â€Å"Happiness in marriage is entirely based a matter of chance.† This is another statement Charlotte makes to Elizabeth in order to let her know that women can only hope to find happiness in a marriage. Marriage was only important for women so they could have balanced, secure financial and social statuses; finding happiness would only be a â€Å"matter of chance†. Austen’s novel illustrates and satirizes the importance of women finding a wealthy husband during that time period: â€Å"You must know that I am thinking of his marrying one of them.† Mrs. Bennett biggest concern was marrying her daughters off to wealthy men such as Mr. Bingley. She knew that marriage was an important issue to all women during that time. Mrs. Bennett found herself a wealthy husband in Mr. Bennett, and hopes that her daughters do the same: â€Å"If I can but see one of my daughters happily settled at Netherfield and all the others equally well married, I shall have nothing to wish for.† If all Bennett girls get married Mrs. Bennett will be happy. She wishes for nothing else but for her daughters to be married to wealthy men. Mrs. Bennett goes as far as to plot to get her daughter, Jane Bennett, sick so she will be able to stay at Netherfield with Mr. Bingley. She herself does anything to get her daughters married because she believes that marriag e is the crucial part of a woman’s life. Not all women during this time period thought marriage should be based solely off money. â€Å"As yet, she cannot be certain of the degree of her own regard, nor of its reasonableness. She has known him only a fortnight.† Elizabeth feels that people should form a relationship with one another and know a little about each other before marriage is considered. Knowing a person for only one night is not enough time for one to familiarize their selves with the other person’s character. She also does not hide her feelings and is quick to express them, which was not truly common at the time. She believes marriage should be based off happiness and is exceedingly serious about the power people have to make each other happy or unhappy. Today marriage does not play such major a role in women’s lives, unlike in Jane Austen’s times. Women, of course, dream of getting married but they do not base their marriages off of money but off of love and happiness. Time changes accompanied with the change of feelings towards women makes the concept of marrying for money archaic. For example, women are deemed equal to men in today’s society. Sequentially women are able to obtain jobs considered suitable for only men. This advancement allows women freedom from men and autonomy in their own homes. Women have become independent and are expected to be more than homemakers. Now, women have the option of daycare for their children while they hold regular jobs. Women are given more opportunities today then they were in the past, and are quick to take advantage of those opportunities. There are special circumstances in which women with little or no education try to get married to men that are â€Å"going places† or even women who are referred to as â€Å"gold-diggers,† who dedicate their lives to finding husbands. Besides these few exceptions, women do not seek out husbands to secure their future financially and socially, like those of the women in Austen’s novel, Pride and Prejudice. After finishing Pride and Prejudice good analytical readers can compare the marriage problems of women in past to women in the present. Marriage was critical to women of the past for financial and social status. On the contrary, today, marriage is not as vital to women financially. Women have not only become financially and socially independent, but independent in all aspects. The present has changed drastically from the past meaning that marriage is not as important to most women today for financial reasons, as in the past.

Phase change lab

We have worked with hot plates and thermometers in other labs before, so we know how to be safe. I wonder what a graph of the changing temperatures over time between the phases would look like. Hypothesis Based on prior learning, I predict that the graph of the water phase changes will not be one straight slope, but instead will plateau, or be flat, and then slope between the change of ice to water, plateau and slope once more between the change of water to steam, and then plateau once more.If we record the temperature of the H2O at regular Intervals, then we will be able to make the predicted graph. Procedure List of Materials: 1 thermometer (Tot 100 OIC 1 beaker (250 or 400 ml), 1 hot plate, CE (enough to fill the beaker), tap water (about 25 ml 1 graduated cylinder (optional), safety goggles, lab apron, at least 1 rag (to clean up spills), pencil/pen, notebook/paper, graph paper, and access to an electrical outlet. Steps: 1. Prepare a data table to collect measurements from the la b.Make sure to put the dependent and independent variables in the correct place. 2. Fill the beaker with ice and add a small amount of water (about 25 ml) 3. Place the beaker on the hot plate with the hot plate TURNED OFF. 4. Take two temperature measurements of the Ice/ water slurry 30 seconds apart. 5. Do not let go of the thermometer. 6. Do not let the thermometer touch the beaker's sides or bottom. 7. Turn the hot plate on to about 6 (about halfway). 8. Collect temperature measurements every 30 seconds.The plateaus were not completely flat and fluctuated between 2 degrees of temperature. We didn't get to record measurements after reaching 100 co because we ran out of time and our outlet wasn't working. Analysis 2. Phase changes are happening to the water during the â€Å"flat† areas of the graph. 3. The water is heating up during the slanted areas of the graph. 4. More than one phase of water is present in the â€Å"flat† areas of the graph. 5. The heat from the ho t late is converted to energy when the water is changing from ice to liquid. 6.The heat from the hot plate is changing the temperature of the water when it is only liquid. 7. The graph would have a slower change in temperature over time if we had twice the amount of water, so the graph would be longer horizontally. My hypothesis was confirmed because our data that showed minuscule fluctuating temperatures for the plateaus and the rise/Jump in temperature for the slopes. However, I had not initially accounted for the slight drop of temperature in the beginning due to the ice lolling the water because the water was room temperature.I learned that plateau points on the graph do not stay only one temperature but instead fluctuate. We did have a possible margin of error due to possible inaccurate temperature readings, not exact temperature readings, inconsistent time, and not exact time intervals. If we do this experiment again, we can try changing the temperature of the initial water ad ded or the amount of water added to see if we produce any noticeable differences. Watching H2O change phases took longer than I though!

The Great Masculine Renunciation Essay - 737 Words

The Great Masculine Renunciation At the end of the 18th century there was one of the most significant events in the history of dress. Men gave up their right to all the bright, more elaborate, and more varied forms of clothing. They left all that to the women. Men abandoned their claim to be considered beautiful. They, instead, aimed at being useful in society. Those who have studied the situation all agree that the causes for these changes were primarily of political and social nature. The also believed that in their origin the causes were associated with the great social upheaval of the French Revolution. One of the purposes of decorative dress was to emphasize distinctions of rank and wealth. These distinctions, however, were†¦show more content†¦The change came when the pants were changed to go all the way down to the ankles. The pants were also a darker color, did not require fancy shoes, because the shoes were not as noticeable with the longer pant legs. Formerly, all work connected with economic acti vities of any kind (the production and distribution of goods or services) was considered degrading to the dignity of those who generally set the fashion. With the new ideals of the French Revolution, mans most important activities were passed in the workshop, the counting-house, or the office. These were the places which had, by long tradition, been associated with a relatively simple attire. The world has become aesthetically poorer for this change, as the result of which brightness and contrast have been replaced by dullness and similarity. There can be little doubt, however, that the drastic reduction of the decorative element in male clothing has, to some extent, achieved its aim. Two questions came about with these changes in clothing. The first being, why didnt these influences change womens costume in the same way as that of men? Taking the history of humanity as a whole, there can be little doubt that men have played a greater part in social life, and have been more easily i nfluenced by social factors, than have women.
