Recurrence relations for moments of different orders of extremes from gamma distribution

Certain recurrence relations for the moments of different orders of the largest order statistic from a gamma distribution with shape parameter p are obtained. By using this it is shown that for obtaining the moment of any order of each order statistic of a sample of size n from the gamma distribution, one has to evaluate at most n-2 single integrals.     

The Role of Positive Psychology in Enhancing Satisfaction,Motivation, and Productivity in the Workplace

Abstract

Positive psychology offers scope for enhancing satisfaction, motivation, and productivity in the workplace. Wiegand and Geller (2004, this issue) point to a number of strategies to enhance individuals' success orientation and conclude their discussion with the actively caring model which appears to be a useful means of representing pivotal facets of a positive and supportive workplace climate. The discussion in this article extends some of the concepts presented in their paper, adapts a model of motivation to develop the Occupational Motivation and Engagement Wheel, and also further discusses some particularly key strategies alluded to by Wiegand and Geller. These include a discussion of workplace resilience, authoritarian versus authoritative leadership/management styles, motivating workplace climates, personal bests, staff morale, flow in work, the value individuals attach to tasks and outcomes, and the centrality of relationships in the performance context. The article concludes with a multi-level “broaden and build” framework for enhancing satisfaction, motivation, and productivity in the workplace.     

A Measure of partial association between disease and genotype for the two-parent problem

The two-parent disease-genotype association problem is studied from the point of view of a coefficient of association between the disease phenotype of the child and the disease phenotypes of the parents, in the presence of some genotypic information about the parents. This coefficient of partial association is derived, and certain tests of hypotheses are constructed. The results are shown to be useful in estimation of recurrence risks, and in understanding the nature of the association between child and parental disease phenotypes.

崛起的中国与国际组织：一种互动关系的分析

国际组织在国际事务中日益活跃是当今世界全球化浪潮的一个重要表现和特征。每个国家的兴衰成败已与国际组织密切相关。中国的崛起、中国国际地位的重要性和特殊性,对中国参与国际组织以及国际组织对中国的认同和接纳,产生了不容忽视的重要影响。当前,中国与国际组织已形成相互影响、彼此促进、良性互动的态势,这对中国的国家发展和国际社会的和平与发展都具有重大意义。     

两种情感概念：涂尔干与柏格森的情感理论比较--兼论二者对情感人类学的启示

涂尔干的消极情感理论触及了情感人类学的根本议题,即个体情感和集体情感的关系问题,同时铺陈出情感人类学的核心议题,即个体情感如何对抗集体情感的问题。柏格森的积极情感化解了这类二元论问题,有利于我们重新思考情感人类学理论的进一步发展。     

从奥尔森学说看孔孟消极革命观的积极意义

孔孟的消极革命观具有积极的意义，这在奥尔森对集体行动的逻辑分析中得到了最新 的说明，但孔孟消极革命观的缺陷也是相当明显的。

Order statistics from non-identical right-truncated Lomax random variables with applications

In this paper, we derive some recurrence relations for the single and the product moments of order statistics from n independent and non-identically distributed Lomax and right-truncated Lomax random variables. These recurrence relations are simple in nature and could be used systematically in order to compute all the single and product moments of all order statistics in a simple recursive manner. The results for order statistics from the multiple-outlier model (with a slippage of p observations) are deduced as special cases. We then apply these results by examining the robustness of censored BLUE's to the presence of multiple outliers. Received: November 30, 1998; revised version: March 8, 2000     

Generalized polya eggenberger family of distributions and its relation to lagrangian katz family

Janardan (1973) introduced the generalized Polya Eggenberger family of distributions (GPED) as a limiting distribution of the generalized Markov-Polya distribution (GMPD). Janardan and Rao (1982) gave a number of characterizing properties of the generalized Markov-Polya and generalized Polya Eggenberger distributions. Here, the GPED family characterized by four parameters, is formally defined and studied. The probability generating function, its moments, and certain recurrence relations with the moments are provided. The Lagrangian Katz family of distributions (Consul and Famoye (1996)) is shown to be a sub-class of the family of GPED (or GPED ₁ ) as it is called in this paper). A generalized Polya Eggenberger distribution of the second kind (GPED ₂ ) is also introduced and some of it's properties are given. Recurrence relations for the probabilities of GPED ₁ and GPED ₂ are given. A number of other structural and characteristic properties of the GPED ₁ are provided, from which the properties of Lagrangian Katz family follow. The parameters of GMPD ₁ are estimated by the method of moments and the maximum likelihood method. An application is provided.
