CRITICAL REVIEW OF THE ROLE OF CRISIS IN INDUCING POLICY CHANGE

Introduction Most nations make policies after they enter serious crisis. There is a general notion that a critical problem requires a critical solution. Thus, nations that came under Nazi or Japanese attack in the eve of the Second World War declared a state of emergency and made sweeping changes to their national policies. These changes had far-reaching impacts on the functioning of the arms of governments and the entire nation had to suspend various activities to implement the policies in response to the crises. However, after World War II, significant events have been considered as turning points in national ...

Description

Ideally, nuclear power refers to the energy released by nuclear plants through processes of fusion and fission. Nuclear energy uses fuel generated from mined and processed uranium to produce steam and generate electricity. The process of producing electricity through nuclear reactors is relatively similar to the way other plants produce electric energy (Ferguson 40). Specifically, the nuclear power station converts the nuclear energy in uranium particles into electricity by splitting the atoms to create heat. The heat is used to turn turbines that are connected to a generator. Subsequently, the generator produces electricity. The main advantage of nuclear energy ...

It is widely believed that nuclear energy continues to grow only because of the industrial lobby from companies and corporations that manufacture equipment for nuclear plants and organizations, as well as government officials, who are associated with the nuclear industry. The first advantage is that using nuclear energy can reduce fossil fuel consumption. But the biggest problem is that despite the safety systems of nuclear power plants the human aspect has always an impact on a nuclear accident and nobody can guarantee that disasters like Chernobyl and Fukushima will not happen again. Nuclear waste is a ...

The results of the study have shown that the two most feasible sources of energy available to man are the solar and nuclear energy. If there is an already working serial production of the devices needed for the capture of solar energy, and already examples of the installation of such systems throughout the world, the future of nuclear energy is not so clear (Seba). Now the most innovative reactors are built in the USA and Japan. These are the reactor of the third generation (Murray and Holbert). However, scientists are claiming they have invented a way to re-use the ...

Nuclear energy is undisputedly a very paramount source of energy in first world countries, Japan included. It involves sophisticated nuclear fission that yields energy. It has been argued that it is not a good source of energy by some internationally known agencies like Forbes. Nuclear power generation in Japan has encountered changes following the tragedy in Fukushima in 2011 for reactor plants being erected so close to the ocean where they are vulnerable to tsunamis. The impacts of the tragedy were felt in the economic as well as political sector. The welfare economics of the state went down because ...

Understanding of the political system of Japan is critical for understanding the major interests of this country and forecasting its behavior. Since the 1950s until the early 2000s the Liberal Democratic Party remained in power. But in the 21st century, it was temporarily ousted by other political forces. In 2012, it regained power and is ruling party in Japan now. What are the reasons behind the LDP’s domination? I will try to explain it not going deep into history but illustrating the most recent developments in Japanese policy. The result of the Japanese parliamentary elections of 16 December ...
