Non-Normal Bivariate Distributions with Normal Marginals

The purpose of this note is to indicate that Fieller's Theorem can be expressed in the matrix formulation of the general linear model. The practical consequence is that one general computer program which can estimate the parameters and test the validity of a pertinent model, can also compute confidence limits for the ratios of any linear combinations of the parameters.     

Does accreditation really matter in public relations practice? How age and experience compare to accreditation

Many scholars and practitioners have suggested accreditation as one way to enhance the professionalism of public relations practice. But, others have questioned whether accreditation really makes a difference and whether experience is a sufficient substitute for accreditation. This study found that, although accredited practitioners were significantly older and had significantly more years of experience compared to their non-accredited counterparts, differences between the groups with respect to seven work categories and five professional competencies remained even when age and years of experience were controlled. The affected work categories were account/client management, strategic planning, public relations program planning, project management, stakeholder relations, issues management, and crisis management. The affected professional competencies were the four-step strategic planning process; ethics and legal issues; communication theory; business literacy; and advanced communication skills. In short, this study refutes the argument that age and professional experience are sufficient substitutes for accreditation in public relations. In fact, they are not.

朝鲜核战略与东北亚地区的核扩散——兼谈对中国周边安全的影响

朝鲜之所以进行核试验，与先前印度、巴基斯坦等国家的“成功”先例不无关系。朝鲜的核武装可能带来的严重后果，会使原本就蠢蠢欲动的日本、韩国甚至台湾等纷纷步朝鲜后尘，有可能走上核开发之路。届时，东北亚必将引发核“多米诺骨牌效应”，这不仅会导致东北亚局势严重不稳，也会使中国成为唯一一个被核国家包围的国家。

图尔明辩论模式下中英新闻评论的诉诸逻辑修辞策略比较

从Aristotle提出的诉诸逻辑角度出发对比分析英汉新闻评论中各自劝说策略的异同。具体在分析诉诸逻辑中使用的劝说策略时,本文借鉴了Toulmin的辩论模式,从claim、reason、evidence和rebuttal四个方面来把握对诉诸逻辑的劝说策略分析。     

Assessing the Moderating Effects of Depressive Symptoms on Antisocial Behavior among Urban Youth in Public Housing

This study assesses whether the influences of attitude towards deviance, exposure to delinquent peers and parental supervision and encouragement on antisocial behavior are moderated by depressive symptoms. Two hundred and thirty eight African American adolescents ages 13–19 from three public housing developments participated in this study. Results indicate that approximately half of the youth did not engage in antisocial behaviors in the last year. Gender, depression, attitudes and peers were significant correlates of antisocial behavior. Parental supervision and encouragement, and age were not related to antisocial behavior. Interaction effects suggest that the relative influences of attitudes towards deviance and delinquent peers on antisocial behaviors depend upon gender and level of depression symptoms. Implications for social work practice and future research are discussed.     

治理理念对调整行业协会与政府关系的指导意义

市场经济的发展必然要求经济性行业协会承担起行业管理的重任。但是我国的行业协会还没有完全实现自治，尤其是在行业协会与政府的关系上，如政社不分和职权不明这些因素严重制约了行业协会的发展。政府应该依循治理念为行业协会提供适当的发展空间，促成政府与行业协会的合作，以实现经济社会的良性循环。     

论三四十年代的女性写作

三四十年代是中国女性写作投身社会运动的时代 ,女性意识的变异使得女作家遮蔽或忽略自身独特的体认而竭力达到一种不分性别的认识高度。导致这种主体意识变化的原因既有社会、历史的因素 ,也有创作主体自身的因素。诸多方面的影响使得她们自觉或不自觉地以社会意识、政治意识作为主体意识的新支点 ,为女性意识注入新的质素 ,从而使文学创作风貌产生新的变化。这种变化几乎是群体性的 ,即整个女性写作都表现出一种对男性趋向的认同     

On some probability distributions associated with random walks

The probability distribution of the total number of games to ruin in a gambler's ruin random walk with initial position n, the probability distribution of the total size of an epidemic starting with n cases and the probability distribution of the number of customers served during a busy period M/M/1 when the service starts with n waiting customers are identical. All these can be easily obtained by using Lagrangian expansions instead of long combinatorial methods. The binomial, trinomial, quadrinomial and polynomial random walks of a particle have been considered with an absorbing barrier at 0 when the particle starts its walks from a point n, and the pgfs. and the probability distributions of the total number of jumps (trials) before absorption at 0 have been obtained. The values for the mean and variance of such walks have also been given.
