Relative Theory - Essay Example earth-bound existence) – can be regarded as tenable. This gave rise to a controversy because in classical mechanics a free fall in a non-gravitational field is known as ‘inertial motion’, i.e. there is no external force applied on the object. But gravity is a force. Therefore, classical mechanics holds the view that ‘inertial objects moving through space cannot accelerate with respect to each other’. Now we come to the crux of the problem – how to reconcile the two seemingly incompatible theoretical postulates? Einstein next proposed an alternative theory in which he argued that the space-time continuum is curved. His subsequent field equations relate the curvature of space-time to the mass, energy and the momentum within it. Hence his famous equation: Now I will come to the point in the article. So called â€Å"Grandfather paradox† is directly related to the same â€Å"traveler-homebody† paradox here. Since space-time curvature as suggested by Einstein would allow us to solve the seemingly irreconcilable twin paradox presented in this article, it might be pertinent here to examine all probabilities of the theory. According to the Grandfather paradox a time traveler who goes back in time will be able to kill his biological grandfather before the latter meets the time traveler’s grandmother so that one of his parents might not be conceived. Logically, this means that he himself might not be born. Now comes the real paradox. Since the time traveler did not go back in time, his grandfather was not killed. Therefore one of his parents was born thus enabling him or her to meet the other. Finally, the time traveler was born. The homebody finds out to his amazement that his brother is now four years younger than him. The logical sequence of events should provide an equally logical outcome. Now let’s look at what the Doppler effect has to offer us by way of an explanation. According to the Doppler effect â€Å"waves that propagate in a

Employee relations-Japan - Speech or Presentation Example include labour market deregulation, changes in nature of employment such as employment duration and permanence, wealth distribution inequality, changes in firm governance, and performance-related pay. Labour market deregulation involves measures by the government and policy makers to simplify and reduce restrictions on already existing labour regulations. The main focus of labour deregulation is to improve productivity and easing employee work. Additionally, labour deregulation seeks to achieve lower prices yet maintaining maximum efficiency and productivity. For example, in Japan there has been laws that facilitate adoption of agency workers who are in most cases women and migrants hence incur less costs in terms of wages. However, this has been met by opposition terming the government as inefficient since this policies are arguably in contrast with the 1985 amendments to the LSL seeking to reduce working hours for women (Kato & Kodama 2014, p.11). In the past, large firms in Japan had adopted a culture of recruiting young people, either fresh from universities or the final year, without necessarily seeking job experience. These young people normally remained in the firms as their career develop within the form by gaining promotions (Firkola 2011, p.2). As a result, this system has given employees a sense of belonging in the respective firms bringing hence feeling as part of the firm and consequently increasing production levels. However, with recent policies has forced a drop on the number of recruitments by the large firms and long term employments have also dropped significantly. Atypical employment refers to employment that is not permanent such as employments on the basis of a fixed term. This implies that after the agreed duration the contract can be either terminated or renewed. One of the emerging issues in Japan in the modern day is adoption of atypical employment. This can be attributed to the increased need to reduce production costs yet maintaining
