RELATION BETWEEN RELEASE PARAMETERS AND THROWING DISTANCE OF THE JAVELIN THROW

The present study was clarified a three-dimensional examination of the relation between the release parameters and throwing distances, in order to understand the initial flight characteristics of javelins. The subjects were 57 right-handed javelin throwers. The measured throwing distances ranged from 45.25 m to 87.17 m. The elite throwers had tendency to significant positive correlation between theoretical distance and initial velocity of javelin release. Throwers who achieved throwing distances of over 70m were observed to have throwing distances that were shorter than their theoretical distances, while those whose throwing distances were under 70 m group had throwing distances that were longer than their theoretical distances. When the data were applied to initial velocity of javelin release, it was equivalent to 26 m/s

A comparative study of unemployment & unstable employment indicators in Great Britain and Japan using micro-data

This paper shows our analysis of comparison of unemployment & unstable employment indicators (called "UUEI" hereinafter) in Great Britain and Japan, using micro-data of Great Britain for the period from 1991 to 2002. We investigated and examined the basic framework of relevant indicators and the comparability of the indicators, and carried out a comparative analysis of UUEI in both countries, based on the framework of the study of visible unemployment indicators, invisible unemployment indicators and unstable employment indicators in Japan. Contrasting aspects exist in UUEI between both countries, partly because of the difference in the conditions in the period of comparison between both countries. The employment structure of Japan is in the process of changing to that of the USA and Europe. However, the gap between the sexes has remained a major factor for the backwardness of the unemployment & unstable employment structure in Japan such as invisibility of unemployment, the high weight of discouraged female workers, etc

An Agent-Based Approach for Social Exclusion from the Perspective of Social Networks

In this paper, we examine the effects of the current state of social exclusion. We focus particularly on the relationship between individual social networks and their effects on reducing social exclusion. To tackle these issues, first, we revise and develop our original 2013 simulation model Secondly, we show the three dimensions of social exclusion as represented in our new simulation model and how these dimensions are passed on to future generations. Thirdly, we examine the relationship between a lack of social connection and the strength of social exclusion and present our results, which show that: 1) the degree of social participation is positively correlated with the number of links for each agent; 2) the gap between agents who have the same number of links is widened at a later point of simulation; 3) the degree of social participation is not correlated with the betweeness centrality of each agent in the random network model, and 4) the degree of social participation is correlated with the betweeness centrality of each agent in the threshold model

An Agent Based Simulation Methodology for Analyzing Poverty and Inequality Problems

本稿では、マルチエージェント型のシミュレーションモデルを用いて貧困層・低所得層への扶助の効果を検討した。(1)財産扶助、(2)貧困層・低所得層の稼得能力の引き上げと稼得の場の提供、を扶助の形態としてモデルに組み込み、1人あたりの財産の変化とジニ係数の変化を比較検討した。検討の結果、以下の二点が明らかとなった。第一は、単に財産を扶助することよりも、貧困層・低所得層の稼得能力を引き上げ、稼得の場を提供することの方が、貧困層・低所得層の1人あたりの財産の伸びが大きくなるということである。第二は、貧困層・低所得層の稼得能力を引き上げると、単に財産を扶助する場合よりも、社会全体の財産格差が縮小するということである
