Transportation - Essay Example Transport through water came after. As time progressed, there was invention of other forms of transport including motor vehicles and railways. Transport by air is the most current. From the evolution of transportation, it is evident that the greatest motivation was volume and speed. The newer forms of transportation led to more goods to be carried and increase in the speed. Transportation is through the land, air, water and outer-space. For all the modes of transportation, energy is needed. In traditional forms of transportation, human and animal, the energy was provided by humans and animals. In traditional water transportation, the energy needed was provided by wind [1]. The major contribution of energy for the modern mode of transportation is petroleum products. The source of fuel is very important to different modes of transport. The fuel used differs from one mode to another. Innovation of new modes of transportation led to innovations on the form of fuels used. Today, innovations that are made improve the current mode of transport and come up with other better modes. The greatest motivation to innovations is to increase speed and safety of transport. In addition, there is need for exploring other parts of space. Land transportation is the oldest mode of transport. This mode includes all forms of transports that are made though the land. ... Use of ethanol and bio diesel is already on the way but there is still more hope for automobiles. The most promising source of fuel in the future is hydrogen. Auto mobile makers are already making progress in making hydrogen fuel cell. Unlike the other types of fuel, hydrogen is renewable. Thus, when this technology is adopted, there will be no fear of losing fuel [1]. This technology on fuel makes the use of a reaction between hydrogen and oxygen. The product of the reaction is electricity that will be used to drive the vehicles. Thus, the future vehicle will be driven by electricity and thus, it will be moving at a very high speed. The speed at which the vehicles will be moving at can only be compared to the speed at which the current electric trains move at. At this speed, there will be need to change infrastructures and transport rules to accommodate the new technology. The greatest motivation to innovations is the desire to protect the environment. Fuels from fossil products are accused of releasing a lot of green house gases in the environment. Thus, there has been a desire to come up with other alternative fuels that would reduce the amount of carbon dioxide in the environment. Enhanced and synthetic gasoline Gasoline mixed with other elements is a promising alternative fuel in the future. Gasoline that does not come from petroleum products will also be produced and used as fuel. Engines that are able to use gasoline as a form of fuel have been made and implemented. The green house gases produced by gasoline are about half of the gases released by liquid petroleum products. Despite this, the desire to reduce the amount of green house gases continues [1]. The crude oil reservoirs are decreasing with the fuel. With over reliance on crude oil as

Learned Helpness - Essay Example These may cause employees to feel that success or recognition is unattainable, thereby inhibiting motivation to improve their performance levels2. Thesis Statement: The purpose of this paper is to investigate learned helplessness among employees in organizations, and examine the creation of desirable motivation states through management interventions such as motivation, and empowerment and resilience, to eliminate learned helplessness among employees. Lyn Abramson and her team suggested that objective events in themselves do not produce learned helplessness. How those events are interpreted, particularly how their attributional dimensions are perceived, play an important part. Usually, the situations that produce learned helplessness give rise to only momentary symptoms of depression, unless there already exists a ‘depressive explanatory style’3. Besides generalizing from an unpleasant experience resulting in passive acceptance of situations, another approach to the theory of learned helplessness underscores a reinforcement process as its basis. That is, when particular behaviors lead to desired rewards and outcomes, people are motivated to repeat those behaviors. The motivation to perform those behaviors is lost when the specific behaviors do not help to achieve desired outcomes4. For example, when a manager regularly takes credit for her subordinates’ successes, while blaming them for their failures, the employees may lose their motivation to work harder than is necessary to keep their jobs. Similarly, when an organization enforces the use of outdated and ineffective procedures resulting in failed outcomes, employees may show little urgency or interest in their work5. The significance of organizationally induced learned helplessness is that â€Å"It often remains even when the barriers to success are removed†6. Consequently, when an unfair manager or restrictive policies are removed, employee motivation and
