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.     

A one-sided test for testino homogeneity of scale parameters against simple ordered alternative

In an earlier paper the authors (1997) extended the results of Hayter (1990) to the two parameter exponential probability model. This paper addressee the extention to the scale parameter case under location-scale probability model. Consider k (k≧3) treatments or competing firms such that an observation from with treatment or firm follows a distribution with cumulative distribution function (cdf) F_i(x)=F[(x-μ_i)/Q_i], where F(·) is any absolutely continuous cdf, i=1,…,k. We propose a test to test the null hypothesis H₀:θ₁=…=θ_k against the simple ordered alternative H₁:θ₁≦…≦θ_k, with at least one strict inequality, using the data X_i,j, i=1,…k; j=1,…,n₁. Two methods to compute the critical points of the proposed test have been demonstrated by talking k two parameter exponential distributions. The test procedure also allows us to construct simultaneous one sided confidence intervals (SOCIs) for the ordered pairwise ratios θ_j/θ_i, 1≦i<j≦k. Statistical simulation revealed that: 9i) actual sizes of the critical points are almost conservative and (ii) power of the proposed test relative to some existing tests is higher.     

Transformed generalized linear models

The estimation of data transformation is very useful to yield response variables satisfying closely a normal linear model. Generalized linear models enable the fitting of models to a wide range of data types. These models are based on exponential dispersion models. We propose a new class of transformed generalized linear models to extend the Box and Cox models and the generalized linear models. We use the generalized linear model framework to fit these models and discuss maximum likelihood estimation and inference. We give a simple formula to estimate the parameter that index the transformation of the response variable for a subclass of models. We also give a simple formula to estimate the r$r$th moment of the original dependent variable. We explore the possibility of using these models to time series data to extend the generalized autoregressive moving average models discussed by Benjamin et al. [Generalized autoregressive moving average models. J. Amer. Statist. Assoc. 98, 214–223]. The usefulness of these models is illustrated in a simulation study and in applications to three real data sets.     

Opportunities and Challenges for Public Libraries to Enhance Community Resilience

This study bridges a gap between public library and emergency management policy versus practice by examining the role of public libraries in the community resource network for disaster recovery. Specifically, this study identifies the opportunities and challenges for public libraries to fulfill their role as a FEMA‐designated essential community organization and enhance community resilience. The results indicate there are several opportunities for libraries to enhance community resilience by offering technology resources and assistance; providing office, meeting, and community living room space; serving as the last redundant communication channel and a repository for community information and disaster narratives; and adapting or expanding services already offered to meet the changing needs of the community. However, libraries also face challenges in enhancing community resilience, including the temptation to overcommit library capacity and staff capability beyond the library mission and a lack of long‐term disaster plans and collaboration with emergency managers and government officials. Implications for library and emergency management practice and crisis research are discussed.     

Family violence laws: Traditional narratives and the (in)visibility of lesbian relationships and lesbian-parented families

Abstract

Feminist advocacy and activism over the last 40 years broke historic ground in shining a light on “domestic” or “family” violence, traditionally conceptualized as male violence against female intimate partners and their children. This has resulted in a large body of research, particularly in the United States, United Kingdom, Australia, and similar jurisdictions, around the gendered nature of family violence and violence within heterosexual relationships and heterosexual-parented families. As a consequence, the predominant narrative—in political, policy, and advocacy settings—is largely heteronormative. Less research has focused on family violence in non-heterosexual relationships. The data that do exist have employed different methodological approaches and there are limitations on the extent to which they can be compared to the data on violence within heterosexual relationships. However, the existing research does demonstrate that family violence within lesbian, gay, bisexual, transgender, and intersex (LGBTI) communities is a significant issue. Even so, the current narrative does not acknowledge this, and predominantly reflects heterosexual norms of intimate relationships and family structures in society. LGBTI relationships are described as “invisible” in policy and practice responses to family violence, due to the failure to acknowledge violence in such communities. This article explores these claims in relation to lesbian relationships in the context of Australian legislative responses to family violence. It considers the extent to which family violence laws in two Australian jurisdictions recognize and frame lesbian identity in intimate relationships and lesbian-parented families. This is considered in light of the emerging conceptualization of family violence in lesbian relationships and lesbian-parented families, as evidenced by the wider scholarly literature on the nature and dynamics of such violence.     

Overcoming the ‘tyranny of the urgent’: integrating gender into disease outbreak preparedness and response

ABSTRACT

This article contributes to discussions on the gender dimensions of disease outbreaks, and preparedness policies and responses, by providing a multi-level analysis of gender-related gaps, particularly illustrating how the failure to challenge gender assumptions and incorporate gender as a priority at the global level has national and local impacts. The implications of neglecting gender dynamics, as well as the potential of equity-based approaches to disease outbreak responses, is illustrated through a case study of the Social Enterprise Network for Development (SEND) Sierra Leone, a non-government organisation (NGO) based in Kailahun, during the Ebola outbreak.     

Determinants of consistent,timely, and active responses in corporate crises

This paper investigates the individual and combined factors affecting the extent to which corporations respond to crisis events consistently, in a timely manner, and actively. The determinants examined include public relations autonomy, legal dominance, strategic orientation, and organizational factors. A survey was conducted of communications mangers, public affairs personnel, and public relations personnel, drawn from the top 500 companies operating in Taiwan. Results indicate that the relative effect of individual sources of influence on crisis response is greatest for situations in which public relations departments have the most autonomy, followed by those where crisis management is handled with a strategic orientation, those where the legal departments dominate, and those where organizational factors provide the main avenue of address. The results emphasize the intriguing role of public relations autonomy by demonstrating its significant impact on providing a consistent, timely, and active crisis response. The strategic orientation of situation analysis also predicts a consistent response, whereas legal dominance predicts strategic ambiguity or inconsistent communication.     

Some Reflections on the Legacies of Michael White: An Australian Perspective

This article, which appears in a special 30‐year anniversary edition of the Australian and New Zealand Journal of Family Therapy, reflects on the legacies of the work of Michael White. It begins by looking back on Michael's time as editor of the Australian Journal of Family Therapy. Of the many themes that were discussed in the Editorials and Letters to the Editor section of this journal in the early 1980s, this article focuses on three in particular to explore the legacies of the work of Michael White. The author describes how Michael has bequeathed not only a profound body of work, but also a distinctive spirit of originating, and ways of working that consider the effects of social issues and that examine the politics of experience. It is the author's hope that this approach to considering Michael White's legacies honours his work and also honours the contributions of the Australian and New Zealand Journal of Family Therapy in its 30th year.     

额什丁家族史论

考察 14世纪以后的苏非派 ,不应忽视额什丁家族的重要作用。这一家族并不是中亚显赫的家族 ,但在特定时期登上了历史的舞台 ,并且其家族首领扮演了较为特别的角色。同时 ,他们和上层统治者有着千丝万缕的联系。这似乎是一种历史的偶然性或者是巧合 ,但仔细探究当时的历史背景 ,不难看出宗教和政治自身需要的内在互动以及或明或暗的结合 ,完成了家族的双重“使命” ,也为一个王朝的灭亡埋下了伏笔
