Without this, our society fall into social dilemma situations, and gets worse and worse. Such a situation in an organization leads to violation of social or organizational rules, and at the worst case it suffers from serious accidents or scandals. Therefore, it is important for organizational managers to make efforts and take measures to enhance cooperative behaviors. Although there seem to be many ways to constantly elicit cooperative behaviors, the punishment is one of the most effective measures for enhancing cooperation. This study focused on the effects of penalty and probability of the revelation of defection on the cooperation, and getting insight into how punishment strategy should be used to get rid of social dilemmas and enhance cooperation. This study conducted a simulation experiment to find the proper penal regulations condition that can suppress violations （defective behavior） in a 2-person prisoner＇s dilemma situation. The effects of probability of the revelation of defection and penalty to revelation on the cooperative behavior were identified with the interactive effect of both experimental factors. The defection （uncooperative behavior） decreased when the penalty to the defection was heavy and the probability of the revelation of defection was low than that when the penalty to the defection was light and the probability of the revelation of the defection was high.展开更多

Scepticism, cynicism, anxiety and penitence as well as the employment of numerous religious images construct the unique and profound characteristics of John Donne＇s poetry. The paper focuses on the Protestant pretence in Donne＇s poetry. In order to avoid religious persecution and to realize his ambition, Donne deserted Catholicism and converted into a Protestant. Inner conflicts and struggle are revealed in many of his poems. Scepticism and penitence are also embodiments of Donne＇s Protestant pretence in poetry.展开更多

First, an analysis is proposed for distributed spectrum sharing based on Prisoners' Dilemma (PD) in Cognitive Radios (CRs). In one-shot game, selfish and rational CRs greedily full spread their own spectrum space in order to maximize their own rates, which leads to Nash Equilibrium (N.E.). But with long term interaction, i.e., Iterated Prisoner's Dilemma (IPD), CRs can come to cooperate and acquire the social optimal point by using different evolutionary strategies such as Tit For Tat (TFT), Generous TFT (GTFT), etc. Also we compare the performances of the different evolutionary strategies in noise-free and noisy environments for two-player games. Finally, N-player IPD (N-IPD) is simulated to verify our conclusions that TFT is a good strategy for spectrum sharing in CRs.展开更多

The content of the statement is obtained by a presentation of the theme in a wide spectrum of writings and pronouncements made by Pope John Paul II who led the Catholic Church from 1978 to 2005, and who is considered to be one of the most prominent voices regarding human dignity and existential issues in contemporary times. Contemplating the crucified and risen Christ enables Christians to talk about a new meaning to suffering as well as of a ＂Gospel of suffering＂. The article enters into themes such as the human predicament when faced with suffering, the mission of those who suffer and solidarity with the suffering.展开更多

By constructing homogeneous random networks from a regular ring graph, we investigate the effects of topologicaJ randomness on cooperation. In contrast to the ordinary view that the presence of smaJ1 amount of shortcuts in ring graphs favors cooperation, we find the cooperation inhibition by weak topological randomness. The explanations on the observations are presented.展开更多

We find that influences of dimets on cooperation depend on the type of dimers and the population structure. For those dimers in which players interact with each other, the cooperation level increases with the number of dimers though the cooperation improvement level depends on the type of network structures. On the other hand, the dimers, in which there are not mutual interactions, will not do any good to the cooperation level in a single community, but interestingly, will improve the cooperation level in a population with two communities. We explore the relationship between dimers and self-interactions and find that the effects of dimers are similar to that of self-interactions. Also, we find that the dimers, which are established over two communities in a multi-community network, act as one type of interaction through which information between communities is communicated by the requirement that two players in a dimer hold a same strategy.展开更多

Different schools thought to aim at savaging the environmental problems which have emerged. While some blame this environmental mess on Social Darwinism, others blame it on Biblical Creationists. On the other side of the ecological debate is the New Age Movement （pantheism）, which to some extent are evolutionist and opposed to the Creator God, though they worship and serve nature （Rom 1：25）. The New-Agers believe that it was as a result of the ＂dominion mandate＂ God gave to humanity that has led to human destruction of the ecology. Some Christians have been indifferent towards nature; because they oppose the New-Agers, they do not want to have anything to do with their views about controlling the environmental problem. Christians are being called upon either to compromise with Darwinian evolution or pantheism （New-Age）. The main concern of this study is to find the meanings of kabash and radah as used in Gen 1：26-28. It also aims at ascertaining the kind of dominion God gave to humanity. Did God grant to man a totalitarian despotic dominion over nature？ Or was the dominion given to man in the form of stewardship？ These are the concerns of this paper.展开更多

Shylock was victimized by the Christian society along with his own. His daughter left him in favor of the Christians. He later became a victimizer but was ironically victimized in turn in wreaking vengeance on his foes in the court. Similarly, Heathcliffs true spiritual love was rejected by His Catherine, neglected by everyone, physically and mentally abused. Later, he wreaked vengeance upon his foes but was victimized to death in turn. Shylock entered the court as a victimizer but left it as a victimized individual just as Heathcliff entered the Heights, after self-imposed exile, as a victimizer and left it as a victimized individual for good. Therefore, both of them experienced a cycle of victimization.展开更多

Over a period of study, I eventually accept the simple emic explanation that ＂it is easy when you are a Christian＂ to be an important explanation. Central to this view is that Christianity provides an alternative religion that allows the people to avoid the need to observe the many troublesome taboos that hinder frequent traveling and engaging in various kinds of economic activities. The influence of relatives is an important factor, too, and as more people become Christians, the traditional Bungan followers lose the support to continue with the traditional religion and eventually almost all follow their relatives to adopt the new religion, which they find do not hinder practicing their culture other than replacing the traditional worship with the Christian way. The ethnographic study provides the opportunity to relate to recent scholarship on the anthropology of Christianity, and facilitates anthropological reflection on the study of cultural change, in particular, in relation to the work of Marshall Sahlins.展开更多

On the other hand, many Evangelical Christians believe that the dead go directly to Heaven to be with the Lord. But in Roman Catholicism, purgatory is considered as the place where most dead believers expiate their remaining sins before entering the visible presence of God. This doctrine has been criticized extensively both by Catholics and Evangelicals in spite of its massive defence by the Holy office. Several alternative views about the resurrection of the dead have been propounded by some twentieth-century Protestants and some notable Catholic theologians. Although the doctrine of purgatory has been approved and reaffirmed by several Church councils, the questions that still remain are： Is the doctrine of purgatory biblically justifiable？ Does the work of salvation extend beyond the grave？ This study attempts to find answers to these questions. The study therefore surveys the doctrine of purgatory in the light of the biblical teachings about death. The second section surveys the background to the doctrine with reference to Judaism, the Apocrypha, the New Testament, the Church Fathers, and Church Councils. The third section looks at the nature of purgatory, the duration and the nature of the punishment meted out to those who go to purgatory and how souls are released from purgatory. The fourth section also examines the biblical teaching on death. The study concludes that the doctrine of purgatory is based on tradition rather than the Bible. The Bible emphasizes the finality of one＇s destiny in this life rather than after this life.展开更多
