Treaty Of Versailles is Justified Essays -- World War I 1 WWI WW1

Treaty of Versailles World War I was ultimately ended in 1918 after the Treaty of Versailles was signed. Peace settlements were signed on June 28, 1918 at the Hall of Mirror in Versailles, Paris. The Treaty was an agreement among the United States, Great Britain, and France. Woodrow Wilson, George Clemenceau, and David Lloyd, who represented the "Big Three" countries, collaborated in negotiating the Treaty. The Treaty of Versailles was designed to weaken Germany and give Germany full blame for causing the war. The Treaty implemented massive reparations to Germany which would obliterate Germany's economy, notwithstanding the millions of dead allied soldiers. The settlement strictly limited the German's military. Germans were additionally forced to depart from their homes in Russia, Poland, and Alsace-Lorraine and return to Germany or Austria. Furthermore Germany had to give back any land belonging to other countries. With no alternative, Germany signed the peace settlements. The Treaty of Versailles was undoubtedly justified, Germany was positively the main instigator of the war and its excessive brutality of fighting provoked the war more particularly. Thus, making the amends to Germany was rational because of all the destruction Germany had triggered. The Treaty of Versailles was fair to Germany because, the primary starter of the war was Germany. Several factors ?conflicts with Serbia- Germany declared wars-invasion of Belgium-Germanys attacking plans, all led to the justification of T of V which proved it was fair. Following the assassination of Archduke Francis, of Austria-Hungry. Germany gave Austria a ?blank check in other terms, an assurance of support no matter the costs. This simple action ties to one factor ... ...the provisions weren?t harsh enough.? Yet some might argue that, ? ..severe as the treaty seemed to be it should be remembered that Germany might easily have forced much more worse, if Clemenceau?s had his way.? However through all the excessive damaged Germans have caused throughout the WWI, to treaty is justifiable. Indisputably the Treaty of Versailles is justified through all the motives that Germany had. The treaty provisions all tie to the start of the new war, World War II. The treaty helped create a cruel regime in Germany and eventually the start of the Nazi party. One fascist leader Adolph Hitler , portrayed such regime. He didn?t want to accept any of the revisions and started to fortify Germany, and went against some T of V provisions, he sent troops to into the Rhineland. Short time after Hitler invaded Poland, which eventually started WWII.

Organizational culture Essay

For a company, organizational culture is very important because the culture is like something that the employee can be based for. In addition, the organizational culture is defined as a system of shared meaning and beliefs within an organization that determines, in a large degree, how employee’s act (Robbins, et al., 2003, p. 70). Founders of new organizations and managers play an important role in creating and maintaining organizational cultures. However, ethical organizational cultures are those in which ethical values and norms are emphasized. As Jones and George (2003, p. 350) argue that ethical organizational cultures can help organizations and their members behave in a socially responsible manner. Some might believe that if they do the ethical corporate culture, they will be able to get much profit. Meanwhile, Arnold and Lampe (1999, pp. 1-19, cited in Robbins, et al., p. 154) claim that the content and strength of an organization’s culture also influences ethical behavior. Nevertheless, a strong culture will have a very powerful and positive influence on managers’ decisions to act ethically and unethically. whereas, in a weak organizational culture, managers are more likely to rely on subculture norms as a behavioral guide. Work groups and departmental standards will strongly influence ethical behaviour in organizations with weak overall cultures. Alongside with organizational culture, there are two more things that have strong correlation with it. The first one is ethics. Ethics is the code of moral principles and values that govern that behavior of a person or group with respect to what is right or wrong (Robbins, et al., 2003, p. 150). The second thing that has strong correlation with culture is social responsibility. It is a management’s obligation to make choices and take action that will contribute to the welfare and interest of society as well as to the interest of the organization (Robbins, et al., 2003, p. 138). Nevertheless, managers who have ethical behavior and social responsibility can build a good reputation for their company. As Donaldson and Werhane (1993, pp.249-254) argue that having a good reputation of a company can increase profit. In addition, Robbins (et al., 2003, pp. 161-165) defines social responsibility is â€Å"an obligation, beyond that required by the law and  economics, for a firm to pursue long-term goals that are good for society†. However, social responsibility is the duty of manager to make decision consider with well-being of stakeholders and society. In fact, there are two main views of management’s social responsibility, which are classical view and socioeconomic view (Robbins, 2003, p. 407). Additionally, classical view aims to maximize profits, whereas socioeconomic view is that social responsibility goes beyond the increasing profit to improve the welfare of society. It is very important that managers support and develop an ethical culture because employees more likely to act ethically if their leader work having an ethical role model (Jones, & George, 2003, pp.101-103). Working ethically is a responsibility to the society. Nevertheless, this is very important as it can avoid harming stakeholders and also enhance the well-being of society as a whole. Stakeholders including employees, customers, suppliers, competitors, governments, media, union, communities, social and political action groups, etc (Robbins, et al., 2003, pp. 92-93). There are still some examples for the reference of socially responsible behavior such as providing training for workers, eliminating discrimination and reducing pollution (Robbins, et al., 2003, p. 407). Providing training for workers can enhance their skills and techniques for work and it can improve the productivity and efficiency. Workers will not be obsolete by the changes of technology so it benefits employees as well as the company (Tsang, 2003, p. 25). Social responsibility and economic growth is related sometimes. At first, the profit may be reduced by the costs of training workers, however, when the trained employees can work efficiently, the productivity will be increased followed by increasing profit at last. Eliminating discrimination is a social responsibility of managers. Some companies would like to employ a specific kind of person but not the others and cause inequality is known as discrimination. For instance, some companies would prefer employ a local student to an international student or they prefer employ man to woman (Pagan, 2000, p. 619). It is harm to firm if they refuse to employ some other races people since they can provide some  new ideas to the company for reference. These new ideas may not be gained from local employers as foreigners have different culture from the local and they can offer some useful information from the other view for the decision making. This is why an organizational culture which has formally adopted a specific position, philosophy, or set of beliefs regarding the fundamental values or principles, is an important thing to be used as the basis for business decision making. Moreover, if managers keep labor Market discrimination, it would lead to society chaotic and harm the society. Therefore, managers should bear the social responsibility to reduce discrimination. Another point that supports an organization to become socially responsible is that when a company being socially responsible, which means that the company has long-term goals. Company should higher the quality of a product to benefit customers to provide a better quality of life (Samli, 1992, p.12). The real example about this is The Body Shop. Although The Body Shop is looking for the profit, they still very concern about the environment. They use goods that not give bad impact on the environment. The product that the body shop sells is more expensive than others because they use the materials that do not give bad impact to the environment. As a result, people still buy their product because people know that they choose the right product. More expensive but in their product, it can’t be found anything that can damage their self and more important damage the environment. As we have seen, by being socially responsible, the firm can gain long-run profit and improve the company’s public image (Davis, et al., 1988, p. 37). In short, it can be seen that being socially responsible and following ethical corporate culture is much more profitable. But, since not all the companies have ethical corporate culture, there are some policies or practices that can be worked to encourage it. Firstly, the company should provide some training for the new and current employee because with the training activities it will make all the employee know about the culture and can adapt with the organization’s culture. Secondly, the company should punish the person who do not obey or perform appropriate with the culture and give respect to the person who perform and do the culture. With that  punishment and respect the employee will think that obey the culture is important. Third, the leaders in the company have to do the culture, so the employee can follow the leader to do the culture. Senior management needs to zealous avoid any decision or action that could reasonably be expected to communicate selfish motive for im posing an ethics philosophy, system, or measurement on employees (www.centeronline.org/knowledge/article.cfm?ID=2431). In conclusion, social responsibility is an important element for a company to success. Social responsibility brings company reputation followed by higher profit. Those firms having social responsibility can improve people’s quality of life and their health. It can also stable the society from chaotic. Therefore, managers should follow regulations and work ethically with the consideration of society’s well-being. Briefly, if one company is concerned about the ethical corporate culture which means that the company and the employee know what is right and wrong and know how to behave in the company. Thus, in one company it is very important to have ethical corporate culture.

lightweight truss construction

The purpose of this paper is to discuss issues concerning the use of lightweight truss construction.   The use of this construction has increased greatly in recent years.   There are many benefits to using lightweight truss constructions.   However, there are also dangers, which will be presented. The main benefit of using lightweight truss wood construction is that it offers builders the opportunity to save lots of money (Pindelski, 2006).   Construction companies are in the business of making money, and therefore many of them prefer to use this new, cheaper construction.   This allows the builders to secure more contracts because they are able to offer lower prices.   Another benefit of using lightweight truss construction is that it makes it easier to install and run utilities and ventilation systems, it is also easy to assemble.   Moreover, this new construction is as strong as traditional structures under normal conditions (Pindelski, 2006). It is clear that there are indeed benefits to using lightweight truss construction, however, as with all types of construction, safety is a major concern.   Research has demonstrated that lightweight truss construction does measure up to desired safety standards.   For example, â€Å"Fire statistics suggest that there is an urgent need for improved performance of light-weight truss construction in fire scenarios,† (Ziemba, 2006, p.2). This creates a serious danger for firefighters and people who occupy buildings, which have caught on fire.   â€Å"Buildings that contain lightweight wood truss construction are susceptible to collapse from fire exposure in a very short amount of time,† (Pindelski, 2006).   This sentiment is further supported in the article Lightweight Truss May Cause Firefighter Death.   â€Å"Without training and building codes that specifically address the fire hazards and threats caused by lightweight truss construction, many civilian and firefighter lives may be lost due to early structural collapse during fire situations,† (Lightweight Truss May Cause Firefighter Death, 2005). Construction companies and builders are now left to decide if the benefits of using lightweight truss construction are worth the risks to human lives.   Firefighter argue that this construction is simply too dangerous, and has cause death for many firefighters.   Unfortunately, many builders to not agree and they assert that firefighters are simply misinformed and exaggerating the dangers of these construction materials.   This debate is likely to continue for years to come.   But there is no doubt that most people agree that saving lives is more important than saving money.   Using lightweight truss constructions is an unsafe practice and it is not worth the risk to human lives or safety.

Being on Time Essay

Being at the right place at the right time for any person is extremely important to the daily life and military life. Being dependable, accountable, and disciplined are all crucial factors that go along with it. Being on time shows that a person is dependable and have his or her priorities straight. Being where one needs to be at the right time always one of the most important aspects of everything you want to succeed in. Failure to be on time not only hinders your time to get tasks done but also wastes the time of those waiting on you. If you want to fix this use good time management. It is important to realize that it is necessary for a person to hold themselves at a higher standard if the wish to excel in life, the military, or whatever you wish to succeed in. Punctuality remains and always will be an extremely vital aspect of military bearing and discipline. It has a direct connection to a person’s appearance, task effectiveness, and essentially every aspect of life and responsibility. I cannot place enough importance on how significant being on time constantly is. For instance; a person who is late or does not report at all to a place at the time stated effectively compromises and reduces the efficiency of which the task or mission at hand can be completed. It also makes it so other people are waiting on you to put out information. This makes it so you waste their time so then they may be late for something and you make them look bad. No one should every try to be sabotaging someone else because of their laziness and inability to be considerate of others. Not being on time also shows that you are not accountable or unaccountable. This is also a direct reflection of yourself and what others feel they should treat you like. Like a wise man once said â€Å"If you act like a child you will be treated like a child.† And really what grown man or women wants to be treated like they are 15 years old and have people hold their hand constantly. Not I not you not anyone. Also by getting this cause from the effect u made of acting like a child it also makes your ability to exceed and excel in life or the military diminish greatly. Also it makes you unreliable and that’s never a good trait to have. Time management is a way to correct this problem. By setting alarms to get up on time, leaving sooner to give yourself enough time to get to one place to another, and making sure you have enough time to do the things you need to do or the things you want to do. Also if you set things up the night before you will not be in such a rush to get things done the next day. If you do not have good time management you will fail in just about every aspect of life in or out of the military. Remember to plan ahead. Good time management is a major key to not make these kinds of mistakes. In conclusion being on time greatly reflects your dependability, accountability, and discipline. These factors affect your opportunity to excel and be the best you can be. Also good time management is key and a way to correct the problem of not being on time. Being on Time Essay Being on time is very important. It is a sign of respect to the person you are meeting. If you are always late, you’re creating a bad reputation for yourself. People feel they can’t trust you or rely on you, so it impacts relationships. It also impacts self-esteem. Being late is upsetting to others and stressful for the one who is late. People’s stress level is very high when they’re late. They’re racing, worried, and anxious. They spend the first few minutes apologizing. And that’s not the best way to making a good impression. So if you want to be on time you must first figure out why you are always late. The reason can usually be classified as either technical or psychological. For example if you’re always late by a different amount of time 5 minutes sometimes, 15, or even 40 minutes other times it is likely that the cause is technical. It’s a case of bad planning, of thinking you need less time than you actually do. Another technical difficulty for some people is the inability to say â€Å"no† to additional commitments when they’re short on time. But if you are literally always 10 minutes late, it’s psychological. You’re arriving exactly when you want. The question is why? For some people, it’s a resistance thing. They don’t want to do what other people expect them to. Another category is the â€Å"crisis-maker†. These are people who cannot get themselves together until they get an adrenaline rush. They need to be under the gun to get them selves moving. There are also people who are late because they worry they won’t have nothing to do while waiting. This problem can be solved easily. Always carry a book or magazine. So you aren’t feeling bored and you don’t have the feeling of â€Å"excess† time when you are waiting. And that’s not the only thing that can help you to deal with lateness. You can also†¦ †¢ Clean out your purse or briefcase each evening so it’s ready to go the next morning. †¢ Know how much money is in your wallet so you won’t run out of cash at an awkward time. †¢ Give up that â€Å"one last thing† before walking out the door. †¢ Think about what you could do with an extra five minutes for every place where you arrive early. †¢ Review your plans for the rest of the day and make note of things that have changed. †¢ Keep a clock in a prominent location so you can check it quickly when you have to leave your activities. †¢ Always keep keys, purse and backpack on hooks and a shelf by the exit door. †¢ Set your clocks 5 to 10 minutes ahead. Although remember that at dinner party it’s rude to arrive early; you might surprise the host and find him in his bathrobe vacuuming. In Japan, China, Germany and the United States being on time is the rule. In other places, such as Latin America punctuality is rare. Punctuality exhibits respect for the time of others; you do not waste their time while they wait for you. But it makes it difficult for Germans to act spontaneously. You can’t really call someone and say, ‘Let’s go for a coffee. ‘ Many Germans will want that date in their diaries for at least a week. Back in the technological dark ages, you couldn’t contact people so easily, so you made an effort to meet them on time. Nowadays if you are running late you simply call the person and delay or cancel the meeting. However that should not become a habit, because you may delay, but time will not. I used to be late all the time. But I’ve got tired of running down the street to catch the bus and bored of explaining to everyone why I’m late again. So I decided to deal with the problem. First step was setting my clocks 5 min ahead and it really works for me. But I realized that everything is in my head. I just have to decide that the meeting or event is just too important for me to be late. I won’t say I’m always on time, but I’m trying. As someone else said: â€Å"Better late than never, but better never late! † [pic].

Do Ex-Military Make Good Police Officers Essay Example | Topics and Well Written Essays - 4000 words

Do Ex-Military Make Good Police Officers - Essay Example The essay "Do Ex-Military Make Good Police Officers?" examine this question identifying which factors will contribute to success within the two types of organizations: military and police. There are certainly parallels between the attributes which make for a successful career in either the military or the police force. However, a successful military record does not necessarily equate to a successful career in law enforcement. The general attributes, such as honesty, integrity, and discipline are commonly valued in both career positions. However, some of the skills in the second group are not necessarily valued in the military. For example, the ability to observe and remember detail has little to do with many functions of military personnel. The ability to assess situations and decide on a course of action is also of little value in many military positions, where instant obedience to the rule might be more valuable. Another factor in police work is the size of the groups, which are generally much smaller than those in the military. Many military positions seek to create groups of very similar people when large groups of very similar people are needed for power. Most groups on police forces are more demanding of dynamic interaction and cross training of team members. The behavior of a military group is expected to be extremely disciplined and nearly thoughtless after orders are given. The groups need to work like well-oiled machines. Individual thought would actually get in the way.
