Discrete Linnik Weibull distribution

Abstract

We introduce a new family of distributions using truncated discrete Linnik distribution. This family is a rich family of distributions which includes many important families of distributions such as Marshall–Olkin family of distributions, family of distributions generated through truncated negative binomial distribution, family of distributions generated through truncated discrete Mittag–Leffler distribution etc. Some properties of the new family of distributions are derived. A particular case of the family, a five parameter generalization of Weibull distribution, namely discrete Linnik Weibull distribution is given special attention. This distribution is a generalization of many distributions, such as extended exponentiated Weibull, exponentiated Weibull, Weibull truncated negative binomial, generalized exponential truncated negative binomial, Marshall-Olkin extended Weibull, Marshall–Olkin generalized exponential, exponential truncated negative binomial, Marshall–Olkin exponential and generalized exponential. The shape properties, moments, median, distribution of order statistics, stochastic ordering and stress–strength properties of the new generalized Weibull distribution are derived. The unknown parameters of the distribution are estimated using maximum likelihood method. The discrete Linnik Weibull distribution is fitted to a survival time data set and it is shown that the distribution is more appropriate than other competitive models.     

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.     

Interdisciplinary Practice in Developmental Disabilities

ABSTRACT

This article explores the development of interdisciplinary team practice within the field of development disabilities. Various interdisciplinary models are described, and the role of the social worker is specifically reviewed. As social workers practice as members of teams in a variety of contexts, a greater understanding of an interdisciplinary approach is warranted.     

唐代的家族、地域与国家认同——唐代“归葬”现象考察

出土的唐代墓志中出现了较多的归葬现象：从唐帝国的边缘地区归葬于国家的中心长安、洛阳。唐代国家观念中的天下观与家国观,蕴含着地域观念和家族观念：地域上是对天下中心的王朝核心区的归属与认同,家族上以忠孝方式表达对家国的忠诚。这为分析唐代的国家认同提供了理路。迁葬或归葬这种耗资巨大的行为仪式即唐代士大夫阶层朴素的国家认同的表达方式。分析唐人的国家认同与唐代社会的互动,有助于吸取历史养分,理解影响国家认同的因素,促进现代的国家认同。     

Spirituality and child welfare reunification: a narrative analysis of successful outcomes

When children are removed from their families because of maltreatment, the child welfare system seeks reunification whenever possible. Despite the importance of this goal, little is known about families who are able to achieve and maintain successful reunification. This qualitative study conducted in‐depth interviews with 15 families who completed their child welfare case plans, were reunited with their children and remained together for at least 1 year post‐reunification. Narrative analysis using a combination of thematic and structural coding was completed to examine the strengths and process families discussed related to their successful child welfare outcomes. This paper discusses one of those strengths, spirituality, in greater depth. Specifically, 12 participants situated the strength of spirituality within their stories as an important narrative element they perceived as critical, leading to important changes. Findings highlight the benefits some families receive from their spiritual beliefs, practices and faith communities when working towards reunification, suggesting child welfare practitioners be prepared to identify and honour this family strength.     

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

年轻夫妇“两头走”——乡村家庭权力结构变迁的新现象

近年来,年轻夫妇“两头走”这一新型家庭居住模式逐渐在鄂西农村变得普遍起来。通过实地调查着重分析了这种物理空间意义上的居住模式重塑的微观家庭权力结构,进而探讨家庭成员间的权利义务关系的变迁。不同于传统从父居模式下的以男方父代家庭与年轻夫妇为主、女方父代家庭较为次要的主次型家庭权力结构,两头走的婚居模式形塑的家庭权力结构为男女双方父代家庭与年轻夫妇的三角平等结构。这对我们认识当下的代际关系与养老、年轻人的独立等问题有着现实意义。     

社会工作视野下失独家庭问题研究现状与前瞻

失独家庭理论的研究最初以问题视角为主,对全面认识和了解失独家庭相关问题具有启示意义,但问题视角对失独家庭成员的潜能和资源的挖掘缺乏关注,而优势视角对失独家庭的问题研究则是一个弥补。在实务研究中,研究者通过实际的干预,探索相关实务介入方法,实现了失独家庭问题研究从“理论”向“实务”的范式转换,但就整体而言实务研究仍处于初级阶段。在失独家庭的社会政策研究中,研究者从社会保障和社会救助2个范畴探讨了现有政策的不足并提出了完善的建议,但是失独家庭的社会政策定位尚不明确,并且相关具体政策的研究相对缺乏。因此,失独家庭的研究可以通过增加行动研究的数量、深化相关实务研究、加强失独家庭的分类研究、明确失独家庭社会政策定位和细化相关社会政策的研究等方面来拓展失独家庭问题的研究。
