Essay on Public Opinion

Essay on Public Opinion Essay on Public Opinion This is a free sample essay on Public Opinion: Public opinion, which can be swayed by the manipulation of the media and to some degree by the President’s persuasion, greatly impacts the policies made by public officials. George Bush promised tax cuts if elected as President of the United States of America. He was able to convince the public that they should be able to spend their money rather than the government. According to the Gallup Poll of September 11-13, 2000 , 74% of the public was in favor of tax cuts. The media’s support of tax cuts was divided; therefore it was not as effective in swaying public opinion as when all media are united in their opinions. Even the Democratic leaders, who were generally against the tax cuts, were unable to prevent the tax cuts. This was due to Democratic leaders like Max Baucus, John Breaux, Blanche Lincoln, and Robert Torricelli who voted in favor of the tax cuts which was guided by the wishes of their constituents. Policies made dealing with Afghanistan cannot be compared to typical policies made by our government officials. These polices are a result of terrorist attacks on America. Because of the nature of the attacks, most everyone agrees on the same policies, which are in the best interests of our country. The ability of President Bush to set specific goals and a unifying cause, has been a major affect in gathering the support of both the people and the media. The Gallup Poll shows that about 90% of the people are in favor of President Bush’s policies at this time . If public opinion should start to change, President Bush would probably reconsider his policies involving Afghanistan, as would any public official when trying to appeal to their constituents. ______________ is a professional essay writing service which can provide high school, college and university students with 100% original custom written essays, research papers, term papers, dissertations, courseworks, homeworks, book reviews, book reports, lab reports, projects, presentations and other assignments of top quality.

Retail and Investment Banking in the UK Essay Example | Topics and Well Written Essays - 2500 words

Retail and Investment Banking in the UK - Essay Example Even though the face of banking may change, the functionality may not be altered in many cases. This, therefore, means that the need to come up with strategies to accommodate the change is necessary. One of the strategies that are brought forward is the use of separation of investment banking from the retail section of banking. Separation of retail banking from investment banking is a strategy that is required as a measure to increase financial stability within a national economy. In this separation, the banks either specialize to perform retail or investment banking in an arrangement known as ring-fencing of the banks (Coppola, 5, September 2014 ). In this arrangement, a local subsidiary of a bank that takes the deposits of local customers is protected from the parent corporation through trade bans and deposits security mechanisms (Song 2004, pp 19). In this way, the deposits of the local customers are protected from external shocks of the economic uncertainties that the large international corporations could have exposed them to. In Great Britain (2012, pp11), the rules that set up the conditions for ring-fenced banks are listed. These rules set the prohibitions that are set for the banks that are set by the regulating authority. In this essay, the effectiveness of the separation of retail banking and investment banking are discussed. The focus of the essay remains if the separation can really bear intended fruits or collapse and the possible consequences of the separation. Investment banking provides services and funds to different sectors of the economy. In doing this, investment banking exposes utilizes the financial capital that is majorly drawn from the savings or deposits of the clients. It means that in a worst-case scenario, if the economic forces force the investments to collapse totally, then the bank is faced with insolvency.  

Henry A. Wallace Questions the 'Get Tough' PolicyAndrei Vishinsky's Essay

Henry A. Wallace Questions the 'Get Tough' PolicyAndrei Vishinsky's United Nations Speech - Essay Example Henry A Wallace â€Å"Questions the Get Tough Policy† The main issue revolving around the mind of Henry Wallace was how the rest of the world views the USA following their day-to-day actions. The reading expounds on the international politics of 1940s. Some of the actions that cause concern are $13 billion budget for the war and Navy Departments, continuing examinations and manufacturing of bombs, the plan to arm the Latin America among other military plans in manufacturing the B-29s and the B-36s. These plans and actions make the USA look as if it is paying so much to earn peace. They may also look as if the US is planning to intimidate the rest of the world or it is planning for an inevitable war. Truly, the best way to enhance peace is investing in arms as this will build a predominance force. However, the USA is doing a lot as far as getting prepared for a war is concerned. Henry Wallace explains these actions of Atomic bomb investment as a cheap warfare as compared with t he outdated wars. This is in reference with the fact that there are a few nations with the capacity to produce the weapon. The production process also requires little labor force and the plant itself occupy a small area as compared to the space occupied by plants manufacturing old rifles. Another reason for investment in atomic bombs is that having many bombs among other nations is of no benefit because they would be of benefit just as having enough weapons would do. Another key reason why the country is producing atomic bombs is that the production will kill the monopoly that a nation such as Russia is producing the weapon. This is through a neutralization effect. He also argues that they are producing the atomic bombs to show preparedness for war, as they are the most venerable nation following the fact that they are the wealthiest nation in the world (Baylis, Smith, and Owens 23). He refers to a philosophy in military studies, which states that there is no nation capable of winni ng a war that fully destroys modern civilization. The theory, therefore, advocates that the best preventative measure is attacking nations, which produce the weapon. The theory by its nature is unethical and immoral. The USA may be at a fix if it decided to apply the theory because if it attempts to attack Russia and all its atomic reserves, it will awaken Europe, meaning in has to destroy it as well which it would be an immense challenge. There are also issues concerning distrust of Russia by the Americans. This is following the conflicts between the two nations as far as political and economic power is concerned. However, there is also an argument that the continuing thought regarding distrust for Russia will not do the world any good because of their reaction concerning the allegation. This is in reference with the history of the nation as well as the policies of Russia to the rest of the world. Following the argument by Henry Wallace, it is evident that the Americans feel that t hey are exceptional and superior to other nations (Baylis, Smith, and Owens 56). Andrei Vishinsky's â€Å"United Nations Speech" â€Å"The Get Policy† by Henry Wallace of 1947 analyzes the need to stop the ongoing after- war propaganda that negatively affected the people. Different individuals share their own opinion about the war, and this is published in the newspapers and daily

New Media Technologies And News Production Essay

New Media Technologies And News Production - Essay Example On the other hand, families saw the need of sitting and watching the television after a day’s work rather than reading newspapers to acquire information. Additionally, the advancement in to the World Wide Web era gave birth to personalized consumption of information since it a was faster and more detailed way of news reporting. News production and the internet Moreover, the information transmission through the internet led to great cultural diversifications in the way of consuming news. The internet is a platform of free culture in that the information provided costs less or is free. Sequentially, the newspapers in the developed nations are unable to compete with the internet in terms of revenue accumulation. Undoubtedly, journalists who find themselves on the receiving end of losing their jobs because of the financial strain in the world today have implemented the use of blogging sites on the internet (Schubert, 2011:5). These blogging sites provide an avenue for the airing o f their views through cheap and reliable means (Stuart 2003:36). They do not find themselves answerable to any one except authorities of their lands of origin. Therefore, the internet has offered a way of bridging the professional gap from that of being unemployed to that of independence for practicing journalists across the globe. On the contrary, citizens have also had their fair contribution in reporting, as the internet offers a platform for posting photographs and amateur video footage on happening events. This is what citizen journalism entails (Greer & McLaughlin, 2010:1045).Once these pictures find their way to the internet, they give room for research where the researching on more facts surrounding the developing story may get to the public domain... This essay stresses that the media has a way of portraying protests and demonstrations by the public in a violent and the non-attractive way. Usually, they portray the demonstrators as those who have high traits of anarchy. This depicts the influence of the media in explaining the actual state happening events. However, governments have emphasized the need for positive reporting rather than negative reporting through the showing of disturbing images. Ideally, negative reporting may affect a country’s economy in that it may bring down a country’s attractiveness to potential investors. Modern day media forms should act as public relations features rather than weapons of ruining public image. Therefore, the media has a role to play in restoring public trust in institutions like the police force that have had the repute of violence and brutality to the public. This paper makes a conclusion that The transformed media has a critical place in the present society because many use it as a matter of the need to feel informed. In this regard, responsible journalism should be the foundation for any coverage of information intending to reach the public domain. Ideally, the media is a tremendously powerful tool that which can influence the society either negatively or positively. Subsequently, the transformed media should ensure that it is impartial and steers the society towards the right direction. Finally, the transformed media forms have defined the standards of living for many of the urban citizens since the reception and production of news is immense quality and class.

Optimal Reactive Power Planning By Using Evolutionary Engineering Essay

Optimal Reactive Power Planning By Using Evolutionary Engineering Essay This paper presents a methodology for solving Optimal Reactive Power Planning (ORPP) problem by using Evolutionary Programming (EP) Optimization Technique in order to improve the voltage stability and minimize the losses in the power system. This study has developed the Evolutionary Programming (EP) Optimization Technique using MATLAB software. The study tested two fitness functions namely total loss minimization and the voltage stability improvement in power system with two different mutation technique. Comparison in the results obtained was made in order to determine the best fitness function and the best mutation technique to be used for solving ORPP and hence the voltage stability is improved. The proposed technique was tested on the IEEE 26 bus reliability test system. Keywords: Optimal Reactive Power Planning (ORPP), Voltage Stability Improvement, Evolutionary Programming (EP) I. INTRODUCTION In general, the problem of optimal reactive power planning (ORPP) can be defined as to determine the amount and location of shunt reactive power compensation devices needed for minimum cost while keeping an adequate voltage profile. The ORPP is one of the most challenging problems since objective functions, the operation cost and the investment cost of new reactive power sources, should be minimized simultaneously [1]. Transmission loss can be minimised by performing reactive power planning which involves optimisation process. The ORPP is a large-scale nonlinear optimization problem with a large number of variables and uncertain parameters. Various mathematical optimization algorithms have been developed for the ORPP, which in most cases; use nonlinear [2], linear [3], or mixed integer programming [4], and decomposition methods [5-8]. However, these conventional techniques are known to converge to a local optimal solution rather than the global one for problems such as ORPP which have many local minima. Recently, evolutionary algorithms (EAs) have been used for optimization; in particular both the genetic algorithm and evo1ution programming have been used in the ORPP problem. The EA is a powerful optimization technique analogous to the natural selection process in genetics. It is useful especially when other optimization methods fail in finding the optimal solution [1]. Evolutionary Programming (EP) optimization technique is recently applied in solving electric power system optimization problems. It is part of the Evolutionary Algorithm (EA) optimization techniques under the artificial intelligence hierarchy. Optimization is an important issue in power system operation and planning particularly in the area of voltage stability studies [9]. In this study, EP engine was initially developed to implement the optimisation process considering two mutation techniques, each with two different objective functions. Comparative studies performed in this study aimed to identify the most suitabl e mutation technique with the best objective function for minimising transmission loss in power system and also improving the voltage stability. The parameters for this problem are: generated reactive power (Qg), injected reactive power (Qinj) and transformer tap (T). Validation on the effectiveness of the proposed technique was conducted on the IEEE-26 reliability test system. Figure 1: The IEEE 26 bus test system II. OBJECTIVES The two objective functions of this study are: To obtain the total loss minimization To improve the voltage stability Where: Total_Loss is total loss minimization LQNmax is voltage stability improvement III. BACKGROUND STUDIES A. Optimal Reactive Power Planning (ORPP) Optimal Reactive Power Planning (ORPP) is a sub-problem of Optimal Power Flow solution which has been widely used in power system operation and planning to determine the optimal control parameter settings, in order to minimize or maximize the desired objective function while satisfying a set of systems constraint. Reactive Power Planning (RPP) involves in optimizing the transformer tap setting, injection of reactive power at generator and load bus so as to fulfill the objective function. Since the OPF approach is commonly concerned with the security and economic operation of the power system, Economic Dispatch (ED) technique is also adopted in RPP scheme. The value of active power generated by the generator is also adjusted in the approach. [11] ORPP is a nonlinear programming problem which has the following mathematical formulation: Maximize or minimize f(x, u) (3) subject to g(x, u) =0 (4) hmin à ¢Ã¢â‚¬ °Ã‚ ¤ h(x, u) à ¢Ã¢â‚¬ °Ã‚ ¥ hmax (5) where u is the vector of control variables and x is the vector of dependent variables. f(x, u) is the objective function, while g(x, u) is the nodal power constraints with hmin à ¢Ã¢â‚¬ °Ã‚ ¤ h(x, u) à ¢Ã¢â‚¬ °Ã‚ ¥ hmax are the inequality constraints of the dependent and independent variables. B. Evolutionary Programming (EP) EP is one of the popular techniques which fall under the Evolutionary Computation in Artificial Intelligence (AI) hierarchy and increasingly applied for solving power system optimization problem in recent years. A new population is formed from an existing population through the use of a mutation operator. This operator produces a new solution by perturbing each component of an existing solution by a random amount. The degree of optimality is measured by the fitness, which can be defined as the objective function of the problem [12]. Through the use of a ranking scheme, the candidate solutions in each population were sorted in ascending order according to the number of the best population. The best population form a resultant population is referred as the next generation. The ranking scheme must have more optimal solutions which has a greater chance of survival than the poorer solutions. It is a stochastic optimization strategy, which based on the mechanics of natural selections-mutation, competition and evolution. This technique stressed on the behavioural linkage between parents and their offspring. In general, EP consists of 3 major steps which briefly discussed as follow [12], [13]: i. Initialization The initial population of ÃŽÂ ¼ individuals consists of (xi, ÆÅ ¾i), ˆ¦i à ¢Ã¢â‚¬Å¡Ã‚ ¬ {1, 2,à ¢Ã¢â€š ¬Ã‚ ¦ÃƒÅ½Ã‚ ¼} are generated randomly based on its limit, whereby xi denotes the control variable and ÆÅ ¾i is the strategic parameter with respect to xi. The fitness is calculated for each individual based on its objective function, f(xi). ii. Mutation a) First Mutation Technique Each parent (xi, ÆÅ ¾i), i=1,à ¢Ã¢â€š ¬Ã‚ ¦, ÃŽÂ ¼, creates a single offspring (xi, ÆÅ ¾i), where xi and ÆÅ ¾i are given by: xi (j) = xi (j) + ÆÅ ¾i (j) Nj (0, 1) (6) ÆÅ ¾i (j) = ÆÅ ¾i (j) exp (à Ã¢â‚¬Å¾ N (0, 1) + à Ã¢â‚¬Å¾ Nj (0, 1)) (7) and à Ã¢â‚¬Å¾ = ((2(n)  ½)  ½)-1 (8) à Ã¢â‚¬Å¾= ((2n)  ½)-1 (9) xi (j), xi'(j), ÆÅ ¾i(j) and ÆÅ ¾i'(j) are the j-th component of the vectors xi, xi, ÆÅ ¾i and ÆÅ ¾i respectively. N(0,1) represents a normally distributed one-dimensional random number with mean zero and standard deviation 1. Nj(0,1) denotes that the random number is generated anew for each value of j. Subsequently, the fitness is calculated for each offspring. b) Proposed Mutation Technique The proposed mutation rule was inspired by neural network back propagation learning. The following three equations are employed for perturbing the parents to generate their offspring: In these equations, xij [k] [k] is the jth variable of an ith individual at the kth generation. The learning rate, ÆÅ ¾, and the momentum rate, ÃŽÂ ±, are real-valued constants that are determined empirically. |.| denotes an absolute value and N represents the normal distribution. Άxij [k] is the amount of change in an individual, which is proportional to the temporal error, and it drives the individual to evolve close to the best individual at the next generation. It may be viewed as a tendency of the other individuals to take after or emulate the best individual in the current generation. sxij [k] is the evolution tendency or momentum of previous evolution. It accumulates evolution information and tends to accelerate convergence when the evolution trajectory is moving in a consistent direction [14]. The best individual is mutated only by the momentum. This expands the exploitation range and increases the possibility for escaping from local minima. acci[k] in (10) is defined as follows. acci[k] = 1; if the current update has improved cost, 0; otherwise. (10) iii. Combination and Selection In combination stage, the union of parents and offspring are ranked in ascending or descending order according to its fitness and purpose of the optimisation. Hence, the top ÃŽÂ ¼ individuals are selected to be parents for the next generation. The process of mutation, combination and selection are repeated until the stopping criterion is met. In this paper, the stopping criterion is taken to be the convergence of fitness value. IV. METHODOLOGY Figure 3 explained the overall methodology for the evolutionary programming optimization technique to solve ORPP. The produced offspring vector must satisfy and consider the constraints as at the initialization. The main concept of EP is the mutation process. Then continues with learning about the MATLAB software and tested the IEEE 26-Bus Test System to observe initial values which are total power loss, initial minimum and maximum voltages and the initial line stability index (LQP LQN). These initial values have been taken by considering the unstable transmission lines in the test system (IEEE 26-BUS). The unstable line means the line stability index value is close to 1.00. The unstable voltage is when the value is not within the range of (0.90à ¢Ã¢â‚¬ °Ã‚ ¤Và ¢Ã¢â‚¬ °Ã‚ ¤1.10). Figure 3: The flow chart for the EP optimization technique The EP program was developed and the analysis of the result is tested based on objective function of the project such as minimize total loss and the voltage stability improvement. Then, the program has been run for five times for each type of objective function. Finally, this project has been concluded and the report has been written. A. Development of EP for Optimal Reactive Power Planning The optimal reactive power planning problems has been tested on the IEEE 26 bus test system. The two objective functions tested are: Fitness1 = Total_Loss; Fitness2 = LQNmax; To find the solution of the problem, the parameters d were decided. The parameters were: Reactive Power of Generator Bus Table 1 shows the parameters and size of reactive power of generation bus. There are five generator buses in IEEE 26-bus test system: Bus 2, 3, 4, 5 and 26. The size of each bus is as below. Table 1: Parameters and size of reactive power of generator bus Parameter Bus Size (MVar) Qg2 2 0 to 50 Qg3 3 0 to 40 Qg4 4 0 to 35 Qg5 5 0 to 30 Qg26 26 0 to 20 2. Injected Reactive Power to the Bus Table 2 shows the parameters and size of injected reactive power to the bus. It shows that there is nine buses have been injected by reactive power. The buses are as below. The unit of the injected reactive power is in MVar.

Transformer Tap at the Transmission Line Table 3 shows the parameters and size of transformer tap at transmission line. It shows that there is seven transformer tap change at transmission line in IEEE 26-bus test system. The size of each transformer tap is (0.9 to 1.2). Table 3: Parameters and size of transformer tap at the transmission line Parameter Line Size (p.u) T1 2-3 0.9 to 1.2 T2 2-13 0.9 to 1.2 T3 3-13 0.9 to 1.2 T4 4-8 0.9 to 1.2 T5 4-12 0.9 to 1.2 T6 6-19 0.9 to 1.2 T7 7-9 0.9 to 1.2 The EP process is initialization, mutation, rank and selection and convergence test. 4.1.1 Initialization Initial population of size 20 is formed by a set of randomly generated actual value. Each member is tested using equation (12) (17) as below. Equations (12) (16) are the generation constraints. The bus voltage limits in equation (17) are stated in order to avoid any violation to the system operation. The total loss limit in equation (18) is stated in order to avoid the losses greater than the initial values. 0MVar à ¢Ã¢â‚¬ °Ã‚ ¤ Qg2 à ¢Ã¢â‚¬ °Ã‚ ¤ 50MVar (12) 0MVar à ¢Ã¢â‚¬ °Ã‚ ¤ Qg3 à ¢Ã¢â‚¬ °Ã‚ ¤ 40MVar (13) 0MVar à ¢Ã¢â‚¬ °Ã‚ ¤ Qg4 à ¢Ã¢â‚¬ °Ã‚ ¤ 35MVar (14) 0MVar à ¢Ã¢â‚¬ °Ã‚ ¤ Qg5 à ¢Ã¢â‚¬ °Ã‚ ¤ 30MVar (15) 0MVar à ¢Ã¢â‚¬ °Ã‚ ¤ Qg26 à ¢Ã¢â‚¬ °Ã‚ ¤ 20MVar (16) 0.90V à ¢Ã¢â‚¬ °Ã‚ ¤Ãƒ ¢Ã¢â‚¬ Ã¢â‚¬Å¡Và ¢Ã¢â‚¬ Ã¢â‚¬Å¡Ãƒ ¢Ã¢â‚¬ °Ã‚ ¤ 1.10V (17) Total Losses à ¢Ã¢â‚¬ °Ã‚ ¤ 16 (18) The generated random numbers must be smaller than the initial solution set in order to make sure that fitness will be improved. Only the member that satisfy the constraints are included in the initial population set. 4.1.2 Mutation Mutation is a method to execute the random number to produce offspring. An offspring vector Li is created from each parent vector by adding Gaussian random with zero mean and standard deviation. 4.1.3 Rank and Selection The offspring populations generated form mutation process is merged with the parent populations. The selection process is to generate a new 20 populations based on the objective function of total losses minimization and the voltage stability improvement. All of members were sorted in ascending order to produce the best twenty or the strongest twenty populations for next generation. 4.1.4 Convergence test The stopping criteria in order to obtain the optimal solution are by looking at the difference in maximum fitness and minimum fitness which must less then certain values. If not achieved, the process will be repeated until it converged. Where: Total_Lossmax- Total_Lossmin LQNmax LQNmin V. RESULTS AND DISCUSSION An EP optimization technique has been developed in this study and tested on IEEE 26-bus test system. The objective function is to minimize the total power loss and to improve the voltage stability in power system. The program has been developed to find the optimal value of control variables based on each objective functions. However, before this program was run, load flow solution for the IEEE 26-bus test system was obtained to determine the initial values. The initial total power loss and stability index is 18.986 MW and 0.754 respectively. For each objective function the program was run five times and the results were tabulated in tables according to the objective function. Then the best result for each objective function was selected and tabulated in Table 1 in the Appendix A in order to make a comparison between the two objective functions. According to the result which tabulated in Table 1 in the Appendix A, it was found that EP optimization technique with voltage stability improvement as the objective function give the best result which is total power loss of 14.462 MW and stability index of 0.717. The EP optimization technique with total power loss minimization as the objective function give results 14.987 MW. The EP optimization technique using proposed mutation rule with voltage stability improvement as objective function, the result MW and for the total power loss and stability index respectively. According Table 4, the total power loss and stability index is 15.534 MW and 0.734 respectively. The result after solve the Optimal Reactive Power Planning (ORPP) is 13.019 MW and 0.699. The percentage reduction for total power loss and stability index after solves the ORPP is 16.19 % and 4.77 %. Table 4: Comparison results before and after solves the Optimal Reactive Power Planning Terms Before Solve ORPP After Solve ORPP Total Power Loss (MW) 15.534 13.019 Stability Index, LQNmax 0.734 0.699 VI. CONCLUSION An evolutionary programming optimization technique has been developed to optimize the real power of generator bus, the reactive power and transformer tap control variables for minimal total cost of generation, total power loss and voltage stability improvement. In this paper, the total cost minimization is the best objective function for minimization of total cost, total power loss and stability index is reduced. The percentage reduction for the total cost and total power loss is acceptable. The percentage reduction of stability index is the highest. The percentage reduces for the total cost, total power loss and stability index is 7.77 %, 16.19 % and 4.77 % respectively. This is the acceptable and reasonable percentage reduction as compared to other objective functions. Therefore voltage stability improvement may not have to be the objective function in order to improve the voltage stability condition of a power system in solving the OPF. VII. FUTURE DEVELOPMENT For future development, the other optimization techniques are proposed to be implemented in solving the ORPP in order to minimize the total power system losses and especially to improve the voltage stability in larger power system. Further modification should be included to get more accurate results for example using different mutation rules and selection strategies. VIII. REFERENCES [1] Kwang. Y. Lee and Frank F.

Integrity: Morality Essay

The definition of integrity is vague and rather open ended. Morals are the premise for all perceptions of integrity and should be further explored to better understand the cloudiness behind integrity. Morals are the standing personal ideas of what basic fibers construct all decisions, right or wrong. But morals are personal, and ever changing, never exactly the same person to person. For example, the Ten Commandments, implemented on primitive people for thousands of years attempted to instill basic morality into barbaric people who, with the fear of a higher power, abided. The late George Carlin summarized these ten into a basic 4. Don’t lie, cheat, steal, or kill. Now, in a civilized world, in a country that defines social civility, these 4 seem easy and almost givens. But, in third world countries where life is not easy, and everyday is eat or be eaten, morals are far less important. Millions, everyday, commit all four acts without hesitation. Morals are expendable when survival lies in the balance. Survival, of what? Survival of life, survival of an idea, survival of a relationship? Millions have killed millions because they thought their agenda was more prevalent, or their god justified it, or because they needed to in order to fulfill the instinctual desire to live at all costs. In no way am I saying that ethics should be readily broken for personal gain, but the principles that so many try to live by aren’t as universally important as they seem. I truly believe that if you are not living for other people, you are not truely living. Relationships mean everything. Its not just the way you treat family, or your friends, its everyone. I treat people how I would want to be treated and give respect where respect is due. My morals are much more diverse then just don’t lie, steal, cheat, or kill . My morals are reflective of today’s day and age, not as dated and black n’ white as those four. My morals are competitive, like our present society. I never intend to hurt anyone, and my actions are far from malicious, but if the survival of something I hold close lies in the balance, I am willing to bend my moral code in order to ensure the continued existence of what I view jeopardized. I stand by what I believe; those are my morals. Live for others, but never forget who is left at the end of the day. I’ve always viewed integrity as personal. Its how you a carry yourself. Its how you act when no one is watching. But, this is all personal. I don’t let other people dictate my integrity, I let my actions speak, and I ask myself at the end of the day, if I acted like the man I want to be. Many days, when I reflect on myself, I realize I haven’t been. And this is life, improving day to day so you never repeat mistakes.

Crime in Society

Crime is something that is within our world every day. If you were to ask people just walking down the street how they would describe a criminal, most would probably speak of the street criminals. Many people do not pay attention to the white collar crimes or the crimes that are not happening around the area that the live in. Crime to me is something that someone does to break a law. Crime is basically something someone would do if they had lost their job and could not take care of their family.They would fend or what they could get, even if it meant break a law or committing a crime. These people would feel as if there was nothing else out there. Society has the options to view crime as they will. Some will define crime as everything is bad if they are breaking a law, they should be punished. Others would define it to be light for some criminals that have punishments and for crimes like murder some would consider this crime is a death penalty case in some societies. Someone can defi ne crime with any of their opinions.Many people define crime as murder, robbery, or even damage to someone else’s property. Many people would consider these crimes to be punishable by law. An accurate statement and crime that we know to be true would be the shooting that happened this year at the movie theater in Colorado. We know that this crime is true because he had guns and ammo hidden within the theater before the incident occurred. Also, that he killed twelve people and injured more than fifty would be another way to show that it is true.It was well planned and thought out for what he was doing and when he was going to do it. There was also eye witnesses that said he looked ready for way. This was one of the deadliest mass shootings in the United States history to date. After they was finished at the scene of the crime, the cops decided to visit his home, in which to find it booby-trapped and found more guns and ammo. One widely misconception that many people have in th e world is that finding someone to pic the crime on is the only thing that the police are worried about when solving a case.This misconception has many mixed feelings throughout the world. My opinion is that as long as they have someone to call a suspect or someone to pin the crime on, they do not care. Another would be that our judicial system is fair to everyone. This statement can be very broad because many things affect the way our system is operated. One last misconception that we have today within the world would be that the death penalty is wanted by everyone. Defenders of the death enalty also suggest that it is a cost-effective way to eliminate the added expense of housing serious criminals in prison for life (Collica & Furst, 2012). Many people with the thoughts of the death penalty have mixed thoughts. Many people share the same feelings I share meaning, I do not think that they should be trying to enforce the death penalty until they fix the corrections within the system s and know that for one hundred percent fact they have the person that committed the crime.Other proponents argue that the execution of the offender will bring closure and will allow survivors to move on with their lives (Armour & Umbreit, 2007; Gross & Matheson, 2003). â€Å"Killing innocents is murder, and if the state does it in our name, because we have demanded it, then we are guilty of it. And if we are all guilty of premeditated murder, then we should all get the death penalty (that is one instance where crime will certainly drop dramatically)† (Leman-Langlois).

Free Essays on The Slave Trade

At the end of the 14th century Europeans started to take people from Africa against their will. Initially they were mainly used as servants for the rich. The Europeans justified the taking of slaves by arguing that they were providing an opportunity for Africans to become Christians. By the 17th century the removal of slaves from Africa became a holy cause that had the full support of the Christian Church. When Spanish and Portuguese sea-captains began to explore the Americas they took their African servants with them. Some of these Africans proved to be excellent explorers. The most important of these was Estevanico, who led the first European expedition to New Mexico and Arizona. The people living in the Americas resisted the attempt by the Europeans to take over their land. One of he most important struggles took place in Cuba in 1512. The Cubans, led by Chief Hatuey, were eventually defeated by the superior weapons of the Spanish. It is estimated that over a million people lived in Cuba before the arrival of the Europeans. Twenty-five years later there were only 2,000 left. Large numbers had been killed, while others died of starvation, disease, committed suicide or had died from the consequences of being forced to work long hours in the gold mines. After the arrival of the Europeans there was a sharp decline in the local population of most of the islands in the Caribbean Sea. This created a problem for the Europeans as they needed labour to exploit the natural resources of these islands. Eventually the Europeans came up with a solution: the importation of slaves from Africa. By 1540, an estimated 10,000 slaves a year were being brought from Africa to replace the diminishing local populations. British merchants became involved in the trade and eventually dominated the market. They built coastal forts in Africa where they kept the captured Africans until the arrival of the slave-ships. The merchants obtained the s... Free Essays on The Slave Trade Free Essays on The Slave Trade At the end of the 14th century Europeans started to take people from Africa against their will.

Sandras Fantasy Professor Ramos Blog

Sandras Fantasy Many artists use their personal lives and experiences they face in order to draw inspiration as well as create art that can only come from within. In the story Never marry a mexican it follows the character Clemencia a young student who falls in love with her teacher who is married yet it leads to a darker turn. When she starts to feel the power she has from within herself to control different aspects in his life and soon starts to obsess over this new found energy. However to the people who have analyzed this character all seem to have the same answer as to why it may be that Clemencia is the way she is. Yet it is never brought up how the author herself can have a direct tie in with the character development placing some of her personal life experiences that are escalated into a dark creative art piece. In this we explain how Sandra Cisneros creative ability to develop this character by not only adding in her our life but in helping us understand the bigger picture of real life prob lems that are presented in a beautiful piece of art. In order to truly understand why Clemencia is the way she is we have to look at the author herself to get a full understanding of why she made this character the way she is. Besides just an author Cisneros dabbles in many different forms of work from poetry, activism, and painting. These play an important part as certain aspects of her life leak into her stories and Clemencia herself. One example of this is from a section of the book in which the author says â€Å"I admit, there was a time when all I wanted was to belong to a man. To wear that gold band on my left hand and be worn on his arm like an expensive jewel brilliant in the light of day.† (Cisneros51). This plays a very crucial role due to the fact the in real life Sandra is not married nor does she have any romantic relationships and appears she would rather be alone. With that being said Sandra may not want a relationship in real life just as the character does not as well in the story but she turns it into a more in teresting read by making it so that Clemica is an over exaggerated version of herself. This opening scene is just one of the many that Cisneros continues to show this fantasy version of herself. Now in the story the author could have chosen any occupation for the young Clemencia to be but she plays out the character to be a substitute teacher who has a strong passion for art. In one scene she talks about how she loves to paint day and night as well as considers the jobs to be compared to prositutuion. She also mentions in that sense that rich people love her creativity and buy their artwork at her exhibitions. It even states in one article that â€Å"Now, the coming-of-age novel – an important contribution to Chicana feminist literature – has also inspired an art exhibit at the National Hispanic Cultural Center in Albuquerque†.(Gonzalez, Carolina Dalia,remeclza.com) . To further help you understand this its almost as Sandra is giving us the more relatable things about herself before driving into the more darker and fictional side side of her. Furthermore Clemencia goes on to talk about buying an apartment with her sister as well as it states in the book that â€Å"Im a person who doesnt belong to any class†.(cisneros55) . As I said prior the author is very well known author and is also recognized for her arts. This shows a direct simile to the character clemencia shes not rich nor poor which in my interpetions means that both the author and the character both share traits of being an artist as well as living very simple kickback life styles . To further back up this claim it also good to note that Cisneros has the funds to be able to live a very fancy lifestyle but just like the book she decides not to and would rather spend her time in her house in mexico.(â€Å"Sandra Cisneros.† Sandra Cisneros, sandracisneros.com/0.) With her involvement in activities sandra is also known to be a femminist which means she believes in equal rights for women so that men and women are on the same level. Thought the stories in her book they all seem to start with a very young girl being taken advantage of or treated horribly by the men in their lives. Now relating back to the story Clemencia appears to have power over Drew and her ability to make him do whatever she feels free too. This could have a big connection to Cisneros personal live in which in her real life she feels women are still dominated in a mans world and the story is her own way of expressing that anger. In order to drive the nail in the coffin there is a statistic of womens labor force in 2024 for hispanc women and it states that in 2024 there will only be 8.4 percent of hispacinc women in the labor force.(U.S Department of Labor.gov). With shocking statistics like that we could see why she would use her stories as a way to vent and get the challeng ing frustration of the problems women face on a daily basis. Through Clemica she is able to fantasize aspects of the women dominating the mans life and even in the process destroying other womens lives. They say art is a replication of life in which we like to use our personal lives and experiences to create art thats different than another. Thats what makes art so beautiful everyone has a different interpretation on it and brings people together to further discuss it. Now the majority of people will say that its just a fictional story and its just the authors way of entertaining the people while telling the truth. While yes I do believe to some extent it does have some entertainment aspect but more so of the author telling us her experience through means of creative storytelling and eventually coming to a life lesson. Regardless artists have inspiration and to me there is always some truth in all fiction.

Leadership theory and practice Essay Example | Topics and Well Written Essays - 2500 words

Leadership theory and practice - Essay Example The essay also seeks to discuss and evaluate the leadership exercised by Anna Bligh during the 2011 flood crisis in Queensland. The analysis will also seek to explore how leadership theories are related to theoretical concepts in the study of motivation, communication and attitudes, and how Anna Bligh’s leadership style has incorporated these aspects. As a point of departure, it is imperative to begin by defining the term leadership in order to gain a clear understanding of the whole concept. Basically, leadership is defined as the social process of influencing people to work voluntarily and persistently towards the attainment of the group or organisational goal (Kuper, 2006). Of notable concern is that leadership may not be restricted to formal position since any person can influence the others towards the achievement of certain goals. The concept of leadership mainly draws from trait and behavioral theories. Trait theories suggest that leaders are born. However, this theory has been challenged by different critics given that any person can be a leader if given the opportunity since leadership is mainly concerned with influencing the behaviour of others. As such, the aspect of behaviour plays a pivotal role in as much as leadership is concerned where there is need for the leaders to appeal to the people to behave in a certain way for the benefit of the group or organisation. The contemporary approach to leadership proposes a principle centered rather than personality based leadership (Schultz, 2003). The leader serves as a role model to his or her followers and encourages similar values in them. As such, leadership research has changed focus from trait to behaviour approach to leadership. Behavioral theories posit to the effect that there are certain behaviours that are supposed to be displayed by the leaders in order for them to be effective in influencing other members of the group towards the attainment of a common goal. Highly influential studies of leadership were conducted at Ohio State University and the University of Michigan. Recent studies in leadership are attributed to the findings of these studies. Thus, the following section of the essay is going to focus on discussing the similarities and differences between these two studies on behavioral leadership and how contingency theories of leadership have developed from these studies. The research that was conducted at Ohio State University sought to identify independent dimensions of leader behaviour. The two dimensions they came up with are called initiating structure and consideration (Robbins, 2003). Initiating structure refers to the extent to which the leader is likely to define the structure of his or her role and those of the employees in search for goal attainment. This is also concerned with behaviour that attempts to organize work and work relationships and the leader is mainly concerned with assigning tasks and ensuring that workers maintain standards of perform ance towards the achievement of organisational goals. The other dimension is consideration which is described as the extent to which the person is likely to have work relations that are characterized by mutual trust, respect of employees’ ideas and feelings. In other words, the leader shows concern for the well being of the employees where their grievances are taken into consideration as a way of

Medical Malpractice Case Study Example | Topics and Well Written Essays - 1000 words

Medical Malpractice - Case Study Example Because we conclude that it is, we reverse and remand. A certain Doris Penrod filed an appeal to the court from a take nothing judgment in favor of David R. Schecter based from a medical malpractice claim. It was in August 2003 that she took her grandmother to a cataract surgery with Dr. Schecter. During the injection process, a small retrobullar hemorrhage occurred that can potentially cause damage to the optic nerve, if there is continued bleeding. After 15 minutes of observation, the RBH did not change; also, there were no swellings in the eyelids, no proptosis and eye discoloration. However, despite these, the surgery was cancelled to prevent any further complications. An eye patch was placed on the observed eye and the patient was discharged, yet after 25 minutes redness was observed around the patch and a large hemorrhage occurred around the eye. Immediately that afternoon, Jessica (Doris Penrod’s granddaughter) called Dr. Schecter (as advised by the doctor himself) but he refused to get the call and at the same time failed Tyenol 3 to the patient, otherwise Dr. Schecter could easily tell them to bring the patient to the hospital. The following day, a visit was paid by both Jessica and Penrod to Dr. Schecter and it was determined that the damaged eye have no vision, though it was able to perceive light. A week later, no vision was still present and the same situation continued until three weeks. Dr. Scheter advised them to see Dr. Roy Levit (a specialist) and it as found out that there was not muscular or retinal damage but a severe ischemic atrophy was diagnosed. Dr, Levit pointed out that the possible cause of this damage is the toxicity from the injection. The jury found out that the negligence of Dr. Schecter was not the proximate cause. Penrod on the other hand filed the complaint together with new and independent cause based that the proximate cause instructions was erroneous. Dr, Schecter pointed out that the error presented by the
