Government of Zanzibar v British Aerospace Essay

Government of Zanzibar v British Aerospace - Essay Example In the case, the Government of Zanzibar had contracted with British Aerospace (supplier) in order to purchase an executive jet from the company. As part of the deal, the Government of Zanzibar entered into a separate contract with a financing company that eventually bought the plane before leasing it back to the government. However, the plane was soon found to be defective. It was returned back to British Aerospace for repair but the faults persisted even after the repair. The Government of Zanzibar immediately stopped its payments of the semiannual installments to the financing company. In order to recover their costs, the financing company (CIBC) took possession of the plane and sold it. The Government of Zanzibar then initiated an action against British Aerospace either to rescind the contract or alternatively be awarded damages under the British contract laws.Additionally, the government of Zanzibar accused the supplier (British Aerospace) of false representation in the contract for having claimed that the Jet was airworthy, reliable and without any construction or design defect. They also appealed to rescind the contract and put them back to the pre-contractual position. For example, it could be by returning plane to the Government in its original position or compensation for damages due to misrepresentation. This was particularly because the government claimed that the contract with British Aerospace is subjected to fraudulent misrepresentation (deceit).

How duration affects the rate of electrolysis in a Voltaic Cell Essay Example for Free

How duration affects the rate of electrolysis in a Voltaic Cell Essay Design and Conduct an experiment to investigate the effect of ONE FACTOR on redox reactions. Introduction:- The two main components of redox reactions are reduction and oxidation. Reduction is a gain in electrons and the decrease in oxidation number whereas oxidation is the loss of electrons and the increase in oxidation number. Voltaic cells, also known as galvanic cells generate their own electricity. The redox reaction in a Voltaic cell is a spontaneous reaction. For this reason, voltaic cells are commonly used as batteries. Voltaic cell reactions supply energy which is used to perform work. The energy is harnessed by situating the oxidation and reduction reactions in separate containers, joined by an apparatus (known as the salt bridge which primarily completes a circuit and maintains electrical neutrality) that allows electrons to flow. The functions of a voltaic cell are quite simple. There happens to be an anode and a cathode. The positive ions go the negative electrode (anode) whereas the negative ions go to the positive electrode (cathode). Electrons always flow from the anode (where oxidation takes place) to the cathode (where reduction takes place). Electrons flow across wires whereas ions flow across the electrolyte and the salt bridge. Aim:- The objective of this experiment is to see how the time affects the mass of the zinc electrode (anode) and the copper electrode (cathode) in a voltaic cell. Variables:- Variable Type of variable How it will be controlled Time (s) Independent (The one you change) Values from 5 to 35 minutes will be used Mass of anode cathode (g) Dependent (The one you measure) Electrodes will be measured after each time interval Current (A) Controlled Measure the current with the help on an ammeter Initial mass of cathode and anode (g) Controlled Weigh out the electrodes using top pan balance from the beginning of the experiment Charge on ion Controlled Use the same solution for all the trials. The charge on the copper ion should be 2+ since the copper 2+ is being converted to copper metal. The charge on the zinc ion should be 0 because Zn is being converted to Zn 2+ Concentration of electrolyte Controlled Use the same solution for all the trials. The solution primarily should be 1 mol dm-3 (just like standard conditions) Area of electrodes (cm2) Controlled Measure the electrodes to ensure they have the same dimensions (92.5cm). Use the same electrodes for all the trials. Volume of electrolyte (cm3) Controlled Use a measuring cylinder to measure out the electrolytes volume Atmosphere which we are working under Controlled Primarily we are working under standard room temperature of 298 K Apparatus:- * 122.5cm2 copper electrode * 122.5cm2 zinc electrode * 100cm3 1mol dm-3 Zinc sulphate solution * 100cm3 1mol dm-3 copper (II) sulphate solution * Filter paper (required to create a salt bridge) * 100cm3 of potassium nitrate solution (the spectator ion which I will require for creating the salt bridge which will complete the circuit and maintain electrical neutrality) * 2x200cm3 beakers * Stopwatch (à ¯Ã‚ ¿Ã‚ ½0.01s) * 1x100cm3 measuring cylinder (à ¯Ã‚ ¿Ã‚ ½1.0cm3) * Voltmeter * 2 connecting wires * Top pan balance (à ¯Ã‚ ¿Ã‚ ½0.01g) Method:- 1) Set up the voltaic cell. Use a measuring cylinder to measure out 100cm3 of copper sulphate solution. Pour it into the 200 cmà ¯Ã‚ ¿Ã‚ ½ beaker. 2) Next do the same for zinc sulphate. Use a measuring cylinder to help measure out 100cm3 of zinc sulphate solution. Pour it into a different 200 cmà ¯Ã‚ ¿Ã‚ ½ beaker. 3) Weigh the masses of the electrodes separately using a top pan balance. Record the initial masses. 4) Connect the wires to the outlets in the zinc and copper electrode. Place them in the corresponding outlets of the voltmeter. 5) After that we cut out some filter paper and dip that into our spectator ion (potassium nitrate) in order to build a salt bridge. The salt bridge will primarily complete the circuit, allow flow of ions and maintain electrical neutrality. The salt bridge will be placed in such a way that the ends of the salt bridge will be touching separate solutions of zinc sulphate and copper sulphate. The overall circuit should resemble the diagram in Figure.1. 6) Place the zinc electrode into the beaker with the zinc sulphate solution and the copper electrode into the beaker with the copper sulphate solution and at the same time, start the stopwatch. Keep the stopwatch running until 200 seconds elapse. *Note- we will be recording the time every 5 minutes because 1 or 2 minutes simply isnt enough for the change to take place 7) Take the cathode out of the solution and measure its mass (remember, before doing so, shake it a couple of times in order to remove any moisture). Record the mass. Do the same for the zinc electrode 8) Place the electrodes into their respective solutions once again and start timing. Repeat steps 5 to 6 9) Repeat the same steps until we get mass readings for up to 60 minutes of experimenting. Data Collection and Processing Raw data:- Initial mass of anode (zinc electrode): 31.29 à ¯Ã‚ ¿Ã‚ ½0.01g Initial mass of cathode (copper electrode): 32.05 à ¯Ã‚ ¿Ã‚ ½0.01g Table 1 Mass of anode and cathode obtained from different time intervals Duration of electrolysis (à ¯Ã‚ ¿Ã‚ ½0.21s) Mass of anode (zinc electrode) (à ¯Ã‚ ¿Ã‚ ½0.01g) Mass of cathode (copper electrode) (à ¯Ã‚ ¿Ã‚ ½0.01g) 300.00 (5 minutes) 31.27 32.08 600.00 (10 minutes) 31.14 32.16 900.00 (15 minutes) 31.08 32.27 1200.00 (20 minutes) 31.00 32.42 1500.00 (25 minutes) 30.83 32.49 1800.00 (30 minutes) 30.61 32.80 2100.00 (35 minutes) 30.25 33.08 Qualitative observations:- We can see that the copper is deposited at the cathode where the cathode begins to get more pink/ brownish colour. Blue colour of copper sulphate solution begins to get paler. Zinc electrode begins to corrode a bit. Most corrosion can be observed at 35 minutes time interval. Note* Uncertainties: The average reaction time was à ¯Ã‚ ¿Ã‚ ½0.5s even though it did alter from interval to interval. Note that there is also a à ¯Ã‚ ¿Ã‚ ½0.01s time uncertainty in the stopwatch itself. The uncertainty for mass is inscribed on the top pan balance as well. Data Processing: We must now calculate the mass changes which have taken place due to experimenting with different time intervals. (Different time intervals would result in a different mass change) This can be calculated simply by doing the following: Mass change = final mass initial mass Due note however that this formula can only be used for calculating the mass change taking place at the cathode (copper electrode where reduction takes place). This is because copper 2+ is being converted to copper metal and is being deposited at the cathode. Obviously this would result in a mass gain at the cathode. Therefore, it would be better for us to use the formula Mass change = final mass initial mass so that it gives us a positive value for the mass change taking place at the cathode. Example 1 Mass change = final mass initial mass = 32.08 32.05 = 0.03g Example 2 Now to calculate the mass change taking place at the anode (zinc electrode), we use the following formula, Mass change = initial mass- final mass. In this case we use this formula because we know that the zinc is being oxidized to zinc 2+ leading the zinc electrode to corrode. This therefore results in a decrease in mass of the anode (zinc electrode). Thus, it would be better for us to use the formula Mass change = initial mass final mass so that it gives us a positive value for the mass change taking place at the anode. Mass change = initial mass final mass = 31.29 31.27 = 0.02 Table 2 -Mass changes of anode and cathode for each time interval Time (à ¯Ã‚ ¿Ã‚ ½0.21s) Mass change of Anode (Zinc electrode)(à ¯Ã‚ ¿Ã‚ ½0.01g) Mass change of cathode (copper electrode) (à ¯Ã‚ ¿Ã‚ ½0.01g) 300.00 (5 minutes) 0.02 0.03 600.00 (10 minutes) 0.15 0.11 900.00 (15 minutes) 0.21 0.22 1200.00 (20 minutes) 0.29 0.37 1500.00 (25 minutes) 0.46 0.44 1800.00 (30 minutes) 0.68 0.75 2100.00 (35 minutes) 1.04 1.03 Graph 1:- Graph 2:- To derive the equation for the two separate reactions, the number of electrons gained or lost during the process has to be deduced. The mass change per minute can be deduced from the gradient. Therefore we first calculate the gradient of graph 1 (mass changes for zinc electrode). For calculating the gradient, find two points which perfectly fits in the grid. In this case, the points (0.04. 100) and (0.08, 200) Gradient= (Y2 Y1) à ¯Ã‚ ¿Ã‚ ½ (X2 X1) = (0.08- 0.04) à ¯Ã‚ ¿Ã‚ ½ (200 100) = (0.04) à ¯Ã‚ ¿Ã‚ ½ (100) = 0.0004 Therefore, the gradient of the first graph is 0.0002. So the mass change per minute for the anode is 0.0004. Next, we calculate the gradient of graph 2 (mass changes for copper electrode). To find the gradient, we work with the points (0.20. 500) and (0.24, 700) Gradient= (Y2 Y1) à ¯Ã‚ ¿Ã‚ ½ (X2 X1) = (700 500) à ¯Ã‚ ¿Ã‚ ½ (0.24- 0.20) = (200) à ¯Ã‚ ¿Ã‚ ½ (0.04) = 0.0002 Therefore, the gradient of the first graph is 0.0002. So the mass change per minute for the cathode is 0.0002. The uncertainties also need to be propagated through the summation of the fractional uncertainties. Uncertainties regarding zinc electrode:- Fractional uncertainty of mass = absolute uncertainty à ¯Ã‚ ¿Ã‚ ½ actual value = 0.01 à ¯Ã‚ ¿Ã‚ ½ 0.02 = 0.500 Fractional uncertainty of time = absolute uncertainty à ¯Ã‚ ¿Ã‚ ½ actual value = 0.21 à ¯Ã‚ ¿Ã‚ ½ 300 = 0.0007 = 0.001 Total uncertainty = 0.001 + 0.500 = 0.501 to 3 decimal places Therefore the rate of change is 0.004 à ¯Ã‚ ¿Ã‚ ½ 0.501 g/s Table 3 Rate of change for each time interval for anode (zinc electrode) Time (à ¯Ã‚ ¿Ã‚ ½0.21s) Rate of change of anode (zinc electrode) (g/s) 60.00 0.004à ¯Ã‚ ¿Ã‚ ½0.501 120.00 0.004à ¯Ã‚ ¿Ã‚ ½0.067 180.00 0.004à ¯Ã‚ ¿Ã‚ ½0.048 240.00 0.004à ¯Ã‚ ¿Ã‚ ½0.035 300.00 0.004à ¯Ã‚ ¿Ã‚ ½0.022 360.00 0.004à ¯Ã‚ ¿Ã‚ ½0.015 420.00 0.004à ¯Ã‚ ¿Ã‚ ½0.001 To calculate the number of electrons in zinc electrode, the following equation may be used:- Number of electrons = molar mass à ¯Ã‚ ¿Ã‚ ½ mass of electrode (mass of one of the samples) = 65.37 à ¯Ã‚ ¿Ã‚ ½ 31.27 = 2.09 Therefore, this would be the half-equation which would occur at the cathode: Zn Zn2.09+ + 2.09e- Due to the loss in a bit more electrons compared to the theoretical formula, it would be a stronger reducing agent therefore the electrode potential would be lower (more negative) than that of the original value. Nevertheless, the electrode potential cannot be determined. Uncertainties regarding copper electrode:- Fractional uncertainty of mass = absolute uncertainty à ¯Ã‚ ¿Ã‚ ½ actual value = 0.01 à ¯Ã‚ ¿Ã‚ ½ 0.03 = 0.333 Fractional uncertainty of time = absolute uncertainty à ¯Ã‚ ¿Ã‚ ½ actual value = 0.21 à ¯Ã‚ ¿Ã‚ ½ 300 = 0.0007 = 0.001 Total uncertainty = 0.001 + 0.333= 0.334 to 3 decimal places Therefore the rate of change is 0.002 à ¯Ã‚ ¿Ã‚ ½ 0.334 g/s Table 3 Rate of change for each time interval for cathode (copper electrode) Time (à ¯Ã‚ ¿Ã‚ ½0.21s) Rate of change of cathode (copper electrode) (g/s) 60.00 0.002à ¯Ã‚ ¿Ã‚ ½0.334 120.00 0.002à ¯Ã‚ ¿Ã‚ ½0.091 180.00 0.002à ¯Ã‚ ¿Ã‚ ½0.046 240.00 0.002à ¯Ã‚ ¿Ã‚ ½0.027 300.00 0.002à ¯Ã‚ ¿Ã‚ ½0.023 360.00 0.002à ¯Ã‚ ¿Ã‚ ½0.013 420.00 0.002à ¯Ã‚ ¿Ã‚ ½0.010 To calculate the number of electrons in copper electrode, the following equation may be used:- Number of electrons = molar mass à ¯Ã‚ ¿Ã‚ ½ mass of electrode (mass of one of the samples) = 65.50 à ¯Ã‚ ¿Ã‚ ½ 32.08 = 2.04 Therefore, this would be the half-equation which would occur at the cathode: Cu2.04+ + 2.04e- Cu Due to the gain of a bit more electrons compared to the theoretical formula, it would be a slightly weaker oxidizing agent therefore the electrode potential would be slightly lower than that of the original value. Nevertheless, the electrode potential cannot be determined. Conclusion My results show that as the duration/ time intervals increase, the mass of the anode (zinc electrode) decreases and the mass of the cathode (copper electrode) increases. We can see that there is a strong positive correlation between the time it takes for both electrodes to change in masses. If the duration is longer, then more electrons flow from the zinc electrode to the copper electrode (anode to cathode) through the electrical wires, while ions flow through the salt bridge to complete. As we know, in a voltaic cell/ galvanic cell, oxidation occurs at the anode (negative electrode) where as reduction occurs at the cathode (positive electrode). Primarily, zinc is oxidized at the anode and converted to zinc 2+. This causes corrosion at the zinc electrode due to the metal being converted to ions thus the mass of the zinc electrode (anode) decreases. On the other hand, copper undergoes reduction at the cathode and the copper 2+ ions get converted to copper metal. This causes the copper metal to be deposited at the cathode thus leading to the copper electrode (cathode) to increase in mass as the duration is increased. The following anodic reaction takes place at the zinc electrode (this is the theoretical equation):- Zn (s) Zn2+ (aq) + 2e- However the equation we found experimentally is:- Zn Zn2.09+ + 2.09e- Hence, this suggests that since the former zinc sample has more electrons to lose, it is an even stronger oxidizing agent compared to the theoretical equation and is slightly higher in the electrochemical series than the latter zinc samples. According to the results that have been gathered, there is a positive correlation between the time it takes to electrolyse an aqueous solution and the rate of electrolysis. The rate of electrolysis was measured using the mass of cathode. If the duration of electrolysis is longer, then more electrons will flow through the circuit and more ions will flow from the anode to the cathode. Oxidation occurs at the anode whereas reduction occurs at the cathode. The cathode gains electrons therefore the mass decreases. The following reaction has taken place (although this is the theoretical equation): Cu2+ (aq) + 2e- Cu (s) However, the experimental equation is: Cu1.75+ + 1.75e- Cu Therefore this implies that since the former copper sample has more electrons to gain, it is a stronger oxidizing agent and it is lower in the electrochemical series than the latter copper sample. The value of the electrode potential hasnt been calculated, however, the number of electrons is 25% off there that shows that there is a great difference between the literature value and the experimental value. According to the graph in the previous page, there is a very strong positive correlation between the mass change and duration of electrolysis as can be deduced from the high R squared value. The change in mass over a certain period of time is very gradual because of the size of the electrons. Although a lot of electrons are able to flow through the electrolyte, there is not such a drastic change. By looking at the graph, almost all the error bars for the points touch the line of best fit which means the data is fairly accurate. The theoretical mass of a copper electrode would be 31.75g. From the results that have been tabulated, the mass of a copper electrode is 36.21g. The percentage error can be calculated using the following formula: Percentage error = difference x 100 theoretical value = 4.46 x 100 31.75 = 14.04% This shows that although there is not such a big difference between the theoretical value and the experimental value. Evaluation Limitation Type of error Improvement The mass of the anode was not measured therefore the rate of electron transfer between the two electrodes could not be determined. This could have increased or decreased the mass of the cathode. Random Measure the mass of the anode The power pack has internal resistance therefore not all the current was emitted. This could have decreased the current, thus decreasing the number of electrons produced. Random Use a resistor to accurately measure the current The top pan balance had a zero offset error. This could have increased the mass of the cathode. Systematic Use the top pan balance with the 0.001 uncertainty to obtain more accurate values. a

Literature Review on Leadership Theories

Literature Review on Leadership Theories 1. Introduction This chapter examined the literature of leadership practices on organizational commitment among managers. The study of leadership is seen as complicated because there has not yet reached any agreement among the researchers in terms of the real meaning of leadership. Professions from different fields around the world such as researchers, philosophers, organizational leaders had attempted to define the concept and meaning of leadership (Woods, 2007). As there are a lot of definitions define by professions around the world about the term of leadership, this study helps to identify the concepts of leadership in order to improve leadership practices on organizational commitment. The elements that will be discussed in this chapter were about theories of leadership that have been argued centuries. Then the definitions of leadership practices and five dimensions of leadership practices will be explained in detail. Lastly, the definition of organizational commitment will also be identified and be elaborated in detail. 2. Leadership Theories There had been existence of arguments about the definition of leadership for several centuries (Woods, 2007). It was indicated that the term of leadership cannot be defined easily. However, the existence of leadership in an organization cannot be denied in terms of its role in achieving the goals and objectives of the organization (Grojean, Resick, Dickson Smith, 2004, p.224). The scientific study of leadership became popular on 20th century and a lot of studies at that time were mainly focused on the effectiveness of leadership (Weinberger, 2009; Yukl, 1998). Daft (2005) defined leadership as a relationship between two parties which were leaders and followers that who were willing to create a shared value and strive toward a shared missions and objectives together (Lee, 2008). Besides that, leadership consisted of the meaning that a leader acts as an example or role model for the employees so that they can follow the step of the leader on the path towards the accomplishment of their tasks (Knab, 2009). The members in an organization tend to create the perceptions of what capabilities and criteria should be posses by an effective leader. Therefore, leadership was seen as effective when the leaders are able to develop and maintain the commitment of the employees through efficient monitoring and encouragement (Knab, 2009). According to Weinberger (2009), leadership can be nurtured in the attitudes and behaviours of the people through consistent training and practices. As many leaders in the leading organizations today are unable to fulfil the needs of team. Therefore, the studies of the leadership in terms of teamwork had received attention by the researchers around the world (Carroll and Levy, 2010). This is because different leader have different attitudes and behaviours. Thus, they will perform in different types of leadership practices under different circumstances (Morgeson, DeRue, and Karam, 2010; McGrath, 1962). In current century, the requirement of a leader to practice well in the leadership is getting more difficult. For the situation nowadays, leaders have to confront with more dynamic environment compared to the working environment that was less challenge for a few centuries ago (Leonard and Lang, 2010). The effective leaders were those who were able to fulfil their obligation perfectly and were able to achieve the expectation of the organization and its stakeholders (Weinberger, 2009; Goleman, 2000). There is no comprehensive of the theory and meaning of the term leadership, so it is difficult to determine what a leader should react and how the leader should behave in a particular situation. Regardless of the various meaning and definition of leadership, it continues to be one of the most widely researched topics today. The previous research on leadership had spur out different types of leadership theories such as Great Man Theory, Trait theory, Contingency Theory, Behavioral Theory, Transactional Theory, and Transformational Theory. Each of the leadership theories mentioned has their own meaning and explanation. The existence of different types of leadership theories indicated the efforts of previous researchers in the studies of leadership. Those theories play important role for the further literature study of the leadership (Morgeson, DeRue, and Karam, 2010). The management styles in Asian countries are different with those in western countries. Therefore, there is difficult to practice the western style of leadership in Asian countries such as Malaysia. Consequently, the leadership styles and theories that are accepted by western countries may not have the notable impact on the management styles of organizations in Malaysia (Lee, 2008). Every leader is different in his or her attitudes, behaviours, and management styles. Hence, there is no single theory works for all leaders. Leaders need to develop their own leadership approach by learning more about the following leadership theories. Great Man Theory Trait theory Contingency Theory Leadership Theories Behavioral Theory Transactional Theory Transformational Theory 2.1.1 Great Man Theory Researchers who support the Great Man Theory believe that people are born with the ability and competency to become a leader (Penn, 2008). The earlier studies defined that Great Man Theory described the leaders that had achieved greatness in their behaviours and attitudes (Daft, 2008). In the new era of today, there are still people that are willing to believe in this theory. Although this theory may sound old-fashioned in the eyes of some people in management team today, research suggests that some people actually possess the intelligence, personality traits, and characteristic that lead them to become good leader (Penn, 2008; Yaverbaum and Sherman, 2008). The term Great Man Theory was first studied by Thomas Carlyle (1841) who suggested that great men are the people that posses the intelligent and created the history of the world. Carlyle argued that great man is born with well personality traits, good behaviours, and high degree of knowledge. They are the people that able to facil itate their power and ability of leadership and open minded which lead them to become a great leader and will leave their footprints in the legend and history (Eckmann, 2005). Leader Born Personality traits Behaviours Knowledge 2.1.2 Trait Theory Trait Theory suggested that an effective leader can be identified through the recognition of his or her traits. Traits are the personal characteristic that possess by a leader, such as intelligence, knowledge, values, ideas, self-confidence, and attire or appearance (Daft, 2008). Trait theory suggested that a leader that complete with perfect and unique characteristic will become an effective leader. There were several studies found that potential leader will posses that similar straits of an effective leader. Trait theory had been neglected in the pass studies of leadership. However, as there had been more researchers explored the studies of leadership theories, more research had been done on this theory in recently years (Penn, 2008). Since the studies about straits theory has getting more popular, more research can be done on other personal traits that a leaders possess such as physical and social characteristic so that a more specific and appropriate trait of an effective leader can be develop. According to Daft (2008), there were some studies of this theory showed that same kind of personal characteristic may not suitable for every situation as the environment is always changing. Leader Characteristics or Traits Intelligence Values Self- confidence Appearance 2.1.3 Contingency Theory Contingency theory suggested that effective leaders will perform an appropriate leadership practices according to the different environment and situation (Penn, 2008). They will commit in the management styles that suitable and acceptable by the employees and organizations. According to this theory, the challenge and environment for every organization was different, so there was no a particular leadership or management style that can fit into all kinds of scenarios. A leadership style will have a positive impact for the organization and its member when the style fulfils the requirement of the situation and expectations of the employees. There were two Contingency had been identified in the past studies which were Path-Goal theory and Situational theory (Penn, 2008). According to Daft (2008), Path- Goal Theory suggested leaders can increase the commitment and enthusiasm of the employees to their jobs through the implementation of the leaders behaviours that fulfil the expectation of the employees. Besides that, this theory emphasized that employees organizational commitment can be increase through the using of reward to show the appreciation of contributions of the employees. On the other hand, Situational Theory emphasized that suitable and appropriate leadership styles will be formed for different situations and leaders have to make sure that their leadership styles are match with the abilities of the subordinates and function in the right situation (Hamilton, 1992). Contingency Theory Path-Goal Theory Situational Theory Leader Behaviour Use of Rewards Right Situation Leadership Style 2.1.4 Behavioral Theory In contrast to other theory discussed above, Behavioural Theory suggested that the actions of leaders will have a positive impact when the leaders perform appropriate behaviours that fit into the situations. In other words, everyone can learn to become a good leader if he or she can match the categories of their behaviours with the appropriate leadership styles (Katsuhiko, 2007; Shapira, 1997). According to Coleman (1986), Blake and Mouton of the University of Texas had proposed a two-dimensional leadership theory called the leadership grid. Each axis on the grid is a nine-point scale, with 1 meaning low concern and 9 meaning high concern. Figure 4.1.4 shows the leadership grid. According to Blake and Mouton (1980), Team management (9,9) was considered as the most effective leadership style because all members in the organizations that work together as a team will complete the tasks faster and can achieve a better result through the process of knowledge sharing in a team. Country club management (1,9) occurred when the leaders were behave to be more concern about the well-being of the employees instead of the productivity of the company. In a contrast, Authority- compliance management (9,1) occurred when the leaders show more concern of the productivity instead of the well-being of the employees. Nevertheless, Middle-of-the-road management (5,5) reflected a moderate amount of concern for both people and production. Impoverished management (1,1) was identified as the worst leadership style as the leaders are not concern for both people in the organization and productivity of the organization. Managers are not put their efforts in the maintaining of the relati onship with the subordinates. They also do not concern of the sustainability of the organizations production. 2.1.5 Transactional Theory Transactional leadership suggested that there was an agreement of contract made between the leader and follower about the obligations of both parties (Penn, 2008). According to the agreement, the followers need to perform and accomplish the task and instructions given by the leaders with full commitment. Instead, leaders have to recognize the contributions of the employees and reward them if the tasks given are being fulfilled effectively. Transactional leadership suggested that people tend to put in more effort in order to complete tasks given when there is existence of the rewards and reorganization. However, in the today diverse working environment that full with challenges, there are getting more people that put in effort to complete the task not by the attraction of rewards, they are doing so due to the self motivation and the inspiration of challenge themselves. Transactional leadership consists of two factors which are contingent reward and management by exception (Bass, 1990) . Contingent reward is formed when there is a mutually agreement between leaders and followers in with the ultimate purpose of achieving the objectives and goals of the company. On the other hand, management by exception is focusing on task execution which means that there is mutual trust between the leaders and the employees. Leaders will try their best in correcting the problems arise in order to maintain employees well performance (Weinberger, 2009). Transactional leadership Contingent Reward Management by Exception Mutual Agreement Focusing on task execution Correcting Problems 2.1.6 Transformational Theory Burns (1978) developed the original idea of Transformational Theory. This theory was defined as a process that transforms people through the motivation, values, and well planning goals which can lead the leaders and followers to higher level of satisfaction and successful in achieving target (Anagnoste, Agoston, Puia, 2010). This theory also indicated the ability of leaders in satisfying the needs and expectations of the followers (Kuhnert Lewis, 1987). Bass (1985) suggested that Transformational Theory emphasized the influence of leaders to the followers by developing a way that can encourage the commitment of the followers to achieve a better performance (McCall, Jr., Morgan, 1986). Transformational leaders tend to have the capability to inspire the subordinates. They always encourage the employees to explore deeper of their potential so that they can be more confident about themselves and can contribute more in the effort of achieving the goals of organization (Carless, 2001). According to Bass (1985), there were four major factors that must be practiced by the leaders that wanted to commit in Transformational Leadership. The first factor was Charisma which emphasized on the characteristics expressed by the leaders that can attract and retain the employees through their persuasive words and actions. The second factor was Inspirational leadership which was defined as a sub factor within charismatic leadership behaviour. The leaders that commit in this leadership have the capability to motivate and influent others through the emotional qualities. The third factor was Individualized Consideration which means that the leaders concern for the needs and development of each employee and they respect the dignity of each employee. The last factor was Intellectual Stimulation which implied the intelligent of leaders in problem solving. They encourage the subordinates in asking question and explore the potential of employees to be creative (McCall, Jr., Morgan, 1986) . Transformational Leadership Charisma Inspirational Individualized Intellectual Leadership Consideration Stimulation 2.2 Leadership Practices There were several aspects of the studies of leadership practices because it compromised by different identifications and reorganization (Morgeson, DeRue, and Karam, 2010). An effective leadership practices is the main key to improve employees achievement. Therefore, the focus on this study is to identify the effectiveness of leadership practices in promoting the followers to achieve higher level of organizational commitment. According to Knab (2009), leaders that perform well leadership practices have the ability to motivate and generate interest of the employees to the jobs. At the same time, they are the leaders that can inspire the employees to strive for the wellness of the organization and productivity and look beyond their own self interest. Kouzes and Posner (1993) suggested that credibility is characteristic that can be learnt by leaders through the experience of previous actions. Leaders that had been through different kinds of challenges tend to be more mature and know the way to handle their relationship with subordinates (Woods, 2007). Leaders are responsible to strive and maintain the credibility through continuing behaviours. With credibility as the essential ingredient of leadership, leaders need to always improve in that particular area in order to increase the trust and commitment of employees to them. Kouzes and Posner (2007) also suggested that the theory of leadership practices had been studied by many researchers and those practices can be studied jointly or independently. According to the previous research, practices of credible leaders can be defined in five categories which are: (a) Challenge the Process (b) Inspire a Shared Vision (c) Enable Others to Act (d) Model the Way (e) Encourage the Heart Leadership can happen at any location, in any form and occur in anytime. The effective leaders that organize the people well can accomplish many and different kinds of difficult tasks. According to Kouzes and Posner (2009), every leader that wanted to success in the leadership must commit in the five dimensions of leadership practices that mentioned earlier. 2.2.1 Challenge the Process The meaning of this Challenge the Process leadership practice was defined detail by Kouzes Posner (1995). The previous studies showed that this particular leadership practice described the characteristic of a leader that always look into the opportunity and space for improvement. They are the group of people that willing to confront with the challenges and risks. Besides that, they always prepare themselves to face the changing of the world (Knab, 2009). Leaders that commit in this leadership practice are not afraid of failure, instead they take failure as a process to grow up and improve. The leadership practice of Challenge the Process emphasized on the attitude of leaders that always prepared to venture out. They are the group of people that able to accept new creations and encourage the followers to accept new products, systems, and processes. In fact, they are the one that bring into the new products or services into the organization. The leaders engaged in this leadership practices are the originators of innovation. Therefore, this leadership practice suggested that the leaders to constantly think the situation from different dimensions so that they can create a different and unexpected new thing that can contribute to the productivity of the organization (Kouzes Posner, 2009). 2.2.2 Inspire a Shared Vision Members of the organization expect their leaders to have a clear image of the future and share the vision with them. Leaders who committed leadership practice of inspire a shared vision will helps everyone to formulate a clear picture about future goals that are acceptable and achievable by everyone (Knab, 2009). Leaders play a significant role in communicates the objectives and future plans to the employees in an effective way, and in the meanwhile inspires them to work towards a shared vision. According to Hyatt (2007), the effective leaders that commit in this leadership practice have to share their ideas with the employees. Therefore, the employees will know the direction that of their effort and will strive towards the goal with full commitment. Besides that, the leadership practice of Inspire a Shared Vision emphasized on the behaviours of the leaders that allow the employees to take part in the forming of future vision (Hyatt, 2007; Gabris Ihrke, 2000). Thus, employees will have a feeling that they are part of the organization and play an important part in future planning. Leaders that engaged in this practice are willing to accept known possibilities of the future. They tend to figure out the outcome first before they give the instructions to start a new project. Therefore, they will form a clear picture about what exactly they are pursuing and the best way to achieve the successful. Furthermore, they create a common and shared vision taking into account of the needs and expectations of all members in the organization (Kouzes Posner, 2009). 2.2.3 Enable Others to Act According to Knab (2009), an effective leader that engaged in leadership practice of Enable Other to Act have the ability to influent others and encourage others to act in the way that expected by the leader. They are the leaders that support and encourage the employees to speak out their mind and contribute their ideas in the projects. Besides that, they always provide options for the employees and inspire the commitment of the employees. This leadership practice emphasized the effort of leaders and subordinates work as a team (Woods, 2007). Therefore, leaders play an important part in nurturing mutual trust within the team members (Hyatt, 2007; Tan Tan, 2000). In order to achieve successful in a project, mutual trust and cooperation among the team members are extremely important. This practice also suggested that leaders enable others to act not by forcing or strictly command. Instead, they encourage others to act through the delegation of power (Hyatt, 2007; Gabris Ihrke, 2000). They allowed the employees to make their own decision as long as the decision they make was for the good of the organization. Moreover, they always use the word we to emphasize the important to work as a team (Kouzes Posner, 2009). Thus, the employees will have a perception that they are on the same boat with others member, then the organizational commitment will increase. 2.2.4 Model the Way The leadership practice of Model the Way suggested that leaders can develop and foster mutual trust between the leader and subordinates and within the subordinates by being the role model for the subordinates (Knab, 2009). Leaders that engaged in this practice are the leaders that ethic, honest and respect dignity of others. They will clearly define the obligations of employees and give a specific instruction so that employees will receive a clear picture of what are the expectations of leaders to them. According to the study of Woods (2007), it was defined that leaders that engaged in this particular leadership practices are able to express themselves with a clear values. Then they will make sure that their behaviour and attitudes are aligned with the values they show to the employees. Competency leaders know that they must involve in the role model expected by employees so that they can gain the trust of the employees and upgrade the commitment of the employees. To be an effective leader that model the way, leaders have to make sure their values and beliefs were accepted by the employees and demonstrate their daily actions that committed to their values and standards (Hyatt, 2007; Gabris Ihrke, 2000). Leaders actions will have more impact on the commitment of the employees than their words or instructions. However, leaders actions must be consistent with what they are promised to the employees. Besides that, leaders have to identify their position in the eyes of employees. They have to make sure that their existence in the organization is important and their instructions always followed by the subordinates. The leadership practice of Model the Way explained the right attitudes that leaders should commit in their direct interaction with employees. The leaders that act as a role model tend to be the leaders that earn the respect of the employees (Kouzes Posner, 2009). 2.2.5 Encourage the Heart Leaders that engaged in leadership practice of Encourage the Heart are willing to show their appreciation to the employees publicly, and always find ways to celebrate the achievement of the subordinates (Knab, 2009). Therefore, people will be more enthusiasm to their job as their contributions are appreciated by the leaders. Besides that, the employees that receive the recognition of the leaders will increase in their self-confidence and self-esteem (Hyatt, 2007; Javidan Waldman, 2003). Thus, they will not be afraid to share their ideas and knowledge with other colleagues. The increase of confidence of employees will then encourage the commitment of employees in their jobs. This will be a competitive advantage for the organization to compete in this challenging world. The high level of organizational commitment among the employees will then increase the productivity ultimately. In the process of upgrading the quality of the products and services require the leaders to motivate the heart of the employees. Leaders play an essential role to ensure that the employees values are align with the objectives of the company (Kouzes Posner, 2009). The leaders that appreciate the effort of the employees will increase the sense of belonging of the employees. When the employees feel that they are a part of the members in the organization, they will be more commit in their jobs and willing to stay with the organization even in the through tough times. 2.3 Organizational Commitment Organizational commitment had received highly attention of the researchers in the previous studies. Previous research had identified that organizational commitment had a significant influence in some aspect of working attitudes and behaviours such as job satisfaction, job performance, and turnover rate (Lee, 2008; Lok and Crawford, 2001; Yousef, 2000). Organizational commitment focuses on employees commitment to the organization. Mowday et al., (1974) explained the definition of organizational commitment as the belief of employees regarding the organizations objectives and values. This will imply the desire of the employees effort and the willingness to contribute to the organization. The employees will be more committed in their organizations if the values and culture of the organizations align with their expectations. Then they will stay loyalty to the organization. According to Cole (2000), a committed worker always believes in companys products and services. He or she is willing to put in a lot of effort and even willing to make sacrifices as long as the purpose is for the good of company. Besides that, the employees are willing to introduce the company to their friends. They will feel proud of their company and recommend their organization to the others as the best place to work for. Furthermore, they will choose to contribute to the company that spur out their organizational commitment rather than the company that provide high salary but absence of the sense of belonging (Lee, 2008). Meyer and Allen (1991) developed three different types of organizational commitment. According to Woods (2007), the three aspects of organizational commitment were defined as below. Affective Commitment This aspect of the commitment described the feeling of employees to the organization that expressed in a positive way. They feel attach to the organization because the organization provided them a sense of belonging. The choose stay in the organization because they want to. Continuance Commitment This aspect of the commitment explained the perceptions of the employees that they will lose their benefits if they leave the organization. Besides that, they afraid to suffer the cost of losing their friendship with colleagues and the cost of losing the economic cost such as insurance, welfare, bonus, and etc. Therefore, they will choose to stay in the organization because they have to. Normative Commitment This aspect of the commitment suggested that the employees continue to contribute to the organization as they have a feeling of obligation. There will be many causes of that feeling. For instance, an employee will have a sense of moral obligation and afraid to leave the company as the company had invested a lot in his or her training. Therefore, the employee will have a perception that he or she has the responsibility to stay still in the organization. As a result, the employees will choose to commit in the organization as they feel that they ought to. 2.4 Summary Leadership was defined in many meanings by researchers and it showed that leadership was indeed plays an important role in todays organization. Although there have been many different theories and definitions of leadership, there is still space for further research about leadership (Lee, 2008). Since it was suggested by previous studies that principal of leadership is the key to improve employees achievement, it is important that we continue to investigate what type of leadership is most effective for the organizations (Knab, 2009). The need for effective and efficient leadership practices are important for the leaders in today organization to engage in. Sufficient and efficient practices of leadership in the organization by leaders will increases the organizational commitment of the employees. As a result, the productivity will also be increased. A leader may have knowledge and skills to act effectively in one situation but he or she may not perform as effectively in a different situation as there is always consist of different challenges in different situation (Lee, 2008; Rad and Yarmohammadian, 2006). In this chapter, the theories of leadership were defined. Subsequently, in this chapter the five leadership practices was explained and its important was discussed as well. Furthermore, the meaning of organizational commitment also be defined and three-component model of commitment was identified.

Graduation Speech -- Graduation Speech, Commencement Address

I stand before you tonight because of love — love that was given to me and displayed in its purest, sacrificial form. This evening, I would like to share with you how that love has changed my life. When my parents enrolled me at Milkins Academy 13 years ago, they recognized the fact that the value of a Christian education is far greater than a new house or car. The material possessions that they have forfeited through the years have allowed me to remain in an environment in which I can see Christ lived out every day. For the sacrificial love that my parents have displayed, together with the parents of all my class members, I am exceedingly grateful. The teachers here at Milkins display love to us students as well. Whether in getting a little extra math help before a test or receiving a needed hug after English class, we experience the love our teachers have for us. Thank you, teachers — all of you. We know that you constantly pray for us, encourage us and reprimand us when we need it. Your love, humility and desire to know Christ have been a brilliant example of what you long to see demonstrated in our lives. God is at work in you, and we pray that everyone here is able to see Christ in us as well. However, although the love of our parents and teachers has greatly influenced our lives, their love is insignificant compared to the love of the One who first loved us. He is the source of all true love and is the ultimate example of sacrifice. One of my favorite passages of Scripture is Romans 5:1-8, which states, "Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ, through whom we have gained access by faith into this grace in which we now stand. And we rejoice in th... ...blameless died, And through it all was tested, shunned, and tried. His life on earth, as all, was but a breath, Yet lived he true until his awful death And after, for although he was but man, He was held in God’s almighty plan, And was truly God in human form; By his death the temple veil was torn. And he calls us all to follow him, Turning from a life of vile sin To perfection by a God all pure; His grace is that of which we can be sure. Blameless Jesus lived and blameless died, And he can be forevermore our Guide. "For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord." Thank you all for coming tonight, and have a lovely evening.

Examination of Some of the images Essay

Wilfred Owen fought throughout the First World War until the last week when he unfortunately died in combat. He must have seen many people in shock from the horrors and destruction of war and that is why he composed a poem about shell shocked soldiers. He said this about his poems: â€Å"My subject is War and the pity of war† this poem is another example of this. It is apparent that Owen believed that the men are no longer human and that they are in fact called â€Å"these†. Since loosing their sanity he no longer thought that the people he saw were anything he could recognise; â€Å"Who are these?† He was obviously shocked by what he had observed. He used the word â€Å"twilight† to set an atmosphere for the rest of the poem. It shows what condition the soldiers were kept in because it was a dark area; moreover it gives the whole place a spooky and chilling aura. Owen described the physical features of the shell shocked soldiers at the beginning poem in a cruel approach. â€Å"Drooping tongues† shows the reader a visual image of a motionless man who could not control his body which meant that his tongue would fall out his mouth. Owen goes on describing the victims; â€Å"jaws that slob their relish† the reader can imagine men with their mouth’s open drooling non stop, almost as if their souls have left only to leave a body to fester. These soldiers must have looked repulsive for Owen to describe a human in this manner. It is obvious that Owen was confused by what he had seen, â€Å"Baring teeth that leer like skulls’ teeth wicked†. He could not explain in a definite sentence how these soldiers became what they were; instead he used language effects like alliteration to establish how the shell shocked soldiers behaved. â€Å"Stroke on stroke of pain† is a sibilance which slowed down the poem. It also gives a harsh sound to signify the non-stop artillery which happened in battle. The writer is telling the reader that one cannot imagine what these people were feeling. â€Å"lungs loved laughter† causes a sound of calm slurring to illustrate the groans of the mental as someone passed through them. It is a very affective approach in producing an image of motionless corpses groaning with madness. This quotation further emphasises the loss of thinking because they once enjoyed their lives only to be desecrated from war. The alliteration of â€Å"m† is used twice in â€Å"Mental Cases†: â€Å"memory†¦murders† and â€Å"multitudinous murders†. The sound which this affect produced was a murmuring noise, perhaps making the reader think that Owen was contemplating something like the beginning of a finished war. He used murders because their souls had gone and were now insane. With the quotation â€Å"heads wear this hilarious, hideous† the sound which is created from it when read out loud is one of panting and gasping. This might symbolise the noise of the shell shocked men, or even Owen was making a flashback of war on the front line with the image of a gas attack and soldiers trying to get air in their lungs. There is also an oxymoron in the sentence which shows that he was confused about why the men were in that current state of health. The most significant quotation which really makes the reader imagine what Owen would have seen is†Awful falseness of set-smiling corpses†. This image makes the reader think deeply about how much the shell shocked victims were disturbed by the war. There are many words and expressions in this poem which were chosen to make sound and also to put an image into the mind of the reader. Often these words make the flashback of the battlefield in which the men became shell shocked from. The phrase â€Å"batter of guns shatter† is an internal rhyme that gives a machine gun fire sound showing pain to the reader. The whole quotation of â€Å"Batter of guns and shatter of flying muscles† gives a sound of war description. It also portrays a very graphic incident of a person that was blown to pieces. It becomes apparent that in the second stanza that Owen is trying to work out why these men had become mentally unstable. In line fifteen he refers back to the thinking of the mental by saying; â€Å"Always they must see things and hear them†. The vital word in this sentence is â€Å"must† it shows that because of their state he thought that they always get shocked by the thought of war. The poet displays his anger in the poem; â€Å"Carnage incomparable, and human squander†. He detested the killing of lives and that included people who were no longer rational. Owen felt that if war never occurred the men â€Å"that had loved laughter† would had been healthy and young. In the last line of the second stanza he came to the conclusion of what happened to the men he had seen; â€Å"Rucked too thick for these men’s extrication†. Owen thought that the problems had gone too far, such as seeing many deaths, for the men to escape from it. The poet knew that these shell shocked men were tortured as every minute went by, â€Å"still their eyeballs shrink tormented†. In â€Å"twilight† the men could cope because there were no flashes of light to distress them, the light might have symbolised the artillery and this would have meant that they did not want to go to war ever again; â€Å"Sunlight seems a blood-smear†¦.Dawn breaks open like a wound that bleeds afresh.† The light symbolises the revisit of war for the shell shocked soldiers. Throughout the poem there are dashes in the poem such as â€Å"-These are men whose minds the Dead have ravished.† Each one of these sentences was written in a slightly different style to the rest of the poem; as if Owen was being shown round a ward full of victims of war by a doctor. In line twenty seven the poem says â€Å"Snatching after us who smote them brother†. Owen wrote this because he thought that the mad people were blaming the living (sane) for what had happened to them. In the last line it says, â€Å"Pawing us who dealt them war and madness.† This excerpt could have many meanings such as the shell shocked victims wanting revenge for those who made them turn insane. Further more, Owen is emphasising the pompous leaders as if they were the people inspecting the hospital realising what they had done. Of course, they had no idea of what â€Å"hellish† orders they â€Å"dealt† to those who fought in The Great War because they were not at th e front line. The whole idea of seeing mental people meant that Owen could not describe the situation in plain English, everything is described metaphorically. The whole impression of the mental people was that they were in a nightmare (Surreal) which they had not yet awaken from. He included the horror, pity and after effects of war to show the reader how â€Å"helpless† men could no longer cope with â€Å"Carnage incomparable† which meant that, in the end, they just broke down.

Wind power is the conversion of wind energy into a useful form of energy, such as using: wind turbines to make electricity, windmills for mechanical power, wind pumps for water pumping or drainage, or sails to propel ships. A large wind farm may consist of several hundred individual wind turbines which are connected to the electric power transmission network. Offshore wind farms can harness more frequent and powerful winds than are available to land-based installations and have less visual impact on the landscape but construction costs are considerably higher.Small onshore wind facilities are used to provide electricity to isolated locations and utility companies increasingly buy back surplus electricity produced by small domestic wind turbines. Although very consistent from year to year, wind power has significant variation over shorter timescales. The intermittency of wind seldom creates problems when used to supply up to 20% of total electricity demand, but as the proportion incre ases, a need to upgrade the grid, and a lowered ability to supplant conventional production can occur.Power management techniques such as having excess capacity storage, dispatch able backing supplies (usually natural gas), storage such as pumped-storage hydroelectricity, exporting and importing power to neighboring areas or reducing demand when wind production is low, can greatly mitigate these problems. Wind power, as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation and uses little land Any effects on the environment are generally less problematic than those from other power sources.As of 2010 wind energy production was over 2. 5% of worldwide power, growing at more than 25% per annum. The overall cost per unit of energy produced is similar to the cost for new coal and natural gas installations. Although wind power is a popular form of energy generation, the construction of wind farms is not u niversally welcomed. Fossil fuels are subsidized by many governments, and wind power and other forms of renewable energy are also often subsidized. For example a 2009 study by the Environmental Law Institute assessed the size and structure of U. S. energy subsidies over the 2002–2008 periods.The study estimated that subsidies to fossil-fuel based sources amounted to approximately $72 billion over this period and subsidies to renewable fuel sources totaled $29 billion. In the United States, the federal government has paid US$74 billion for energy subsidies to support R&D for nuclear power ($50 billion) and fossil fuels ($24 billion) from 1973 to 2003. (Energy subsidies are measures that keep prices for consumers below market levels or for producers above market levels, or reduce costs) During this same timeframe, renewable energy technologies and energy efficiency received a total of US$26 billion.It has been suggested that a subsidy shift would help to level the playing field and support growing energy sectors, namely solar power, wind power, and biofuels. History shows that no energy sector was developed without subsidies. According to the International Energy Agency (IEA) (2011) energy subsidies artificially lower the price of energy paid by consumers, raise the price received by producers or lower the cost of production. â€Å"Fossil fuels subsidies costs generally outweigh the benefits.Subsidies to renewables and low-carbon energy technologies can bring long-term economic and environmental benefits†. In November 2011, an IEA report entitled Deploying Renewables 2011 said â€Å"subsidies in green energy technologies that were not yet competitive are justified in order to give an incentive to investing into technologies with clear environmental and energy security benefits†. The IEA's report disagreed with claims that renewable energy technologies are only viable through costly subsidies and not able to produce energy reliably to meet de mand.In the US, the wind power industry has recently increased its lobbying efforts considerably, spending about $5 million in 2009 after years of relative obscurity in Washington. By comparison, the US nuclear industry alone spent over $650 million on its lobbying efforts and campaign contributions during a single ten year period ending in 2008. Following the 2011 Japanese nuclear accidents, Germany's federal government is working on a new plan for increasing energy efficiency and renewable energy commercialization, with a particular focus on offshore wind farms.Under the plan large wind turbines will be erected far away from the coastlines, where the wind blows more consistently than it does on land, and where the enormous turbines won't bother the inhabitants. The plan aims to decrease Germany's dependence on energy derived from coal and nuclear power plants. Commenting on the EU's 2020 renewable energy target, Economist, Professor Dieter Helm, is critical of how the costs of win d power are cited by lobbyists. Helm also says that the problem of intermittent supply will probably lead to another dash-for-gas or dash-for-coal inEurope, possibly with a negative impact on energy security. A House of Lords Select Committee report (2008) on renewable energy in the UK reported a â€Å"concern over the prospective role of wind generated and other intermittent sources of electricity in the UK, in the absence of a break-through in electricity storage technology or the integration of the UK grid with that of continental Europe. Many wind power companies work with local communities to reduce environmental and other concerns associated with particular wind farms. In other cases there is direct community ownership of wind farm projects.Appropriate government consultation, planning and approval procedures also help to minimize environmental risks. Some may still object to wind farms but, according to The Australia Institute, their concerns should be weighed against the ne ed to address the threats posed by climate change and the opinions of the broader community. In America, wind projects are reported to boost local tax bases, helping to pay for schools, roads and hospitals. Wind projects also revitalize the economy of rural communities by providing steady income to farmers and other landowners.In the UK, both the National Trust and the Campaign to Protect Rural England have expressed concerns about the effects on the rural landscape caused by inappropriately sited wind turbines and wind farms. Some wind farms have become tourist attractions. The White lee Wind Farm Visitor Centre has an exhibition room, a learning hub, a cafe with a viewing deck and also a shop. It is run by the Glasgow Science Centre. In Denmark, a loss-of-value scheme gives people the right to claim compensation for loss of value of their property if it is caused by proximity to a wind turbine.The loss must be at least 1% of the property’s value. There have been numerous re ports of those living close to wind turbines suffering adverse health effects from noise, vibration and shadow flicker, and in 2009 New York Pediatrician, Dr. Nina Pierpont, claimed to have identified an effect for which she coined the term â€Å"Wind Turbine Syndrome†. An industry commissioned review of the current research on the possible health effects of wind turbine noise and vibration reported in 2010 that, â€Å"the sound (including sub audible sound) is not unique, and does not pose a risk to human health.Although the sound may cause ‘annoyance’ for some people, this in itself is not an adverse health effect. † The findings of the report have, however, been questioned on a number of grounds including; that the reviewing group did not include an epidemiologist, usually a given for assessing potential environmental health hazards, and that there was no clear description of the methods the researchers used to search for available research, nor how the y rated the quality of the research. In October 2010 The Society for Wind Vigilance held an international symposium concerning the subject.A study on wind farm noise published in 2012 by The US state of Massachusetts reported that people are annoyed by sound from wind turbines at far lower sound levels than they are by noises from railroads, aircraft, or road traffic. The study found the percentage of respondents who found noise levels highly annoying rose quickly as sound levels increased above about 37dbA (about the level of a conversation). Wind Power Is A very good resource for energy I think that everybody should use win power in the future
