Likelihood ratio order of parallel systems under multiple-outlier models

This paper studies the likelihood ratio ordering of parallel systems under multiple-outlier models. We introduce a partial order, the so-called θ-order, and show that the θ-order between the parameter vectors of the parallel systems implies the likelihood ratio order between the systems.     

Likelihood ratio tests for multivariate normality

This paper presents some powerful omnibus tests for multivariate normality based on the likelihood ratio and the characterizations of the multivariate normal distribution. The power of the proposed tests is studied against various alternatives via Monte Carlo simulations. Simulation studies show our tests compare well with other powerful tests including multivariate versions of the Shapiro–Wilk test and the Anderson–Darling test.     

Fixed T dynamic panel data estimators with multifactor errors

This article analyzes a growing group of fixed T dynamic panel data estimators with a multifactor error structure. We use a unified notational approach to describe these estimators and discuss their properties in terms of deviations from an underlying set of basic assumptions. Furthermore, we consider the extendability of these estimators to practical situations that may frequently arise, such as their ability to accommodate unbalanced panels and common observed factors. Using a large-scale simulation exercise, we consider scenarios that remain largely unexplored in the literature, albeit being of great empirical relevance. In particular, we examine (i) the effect of the presence of weakly exogenous covariates, (ii) the effect of changing the magnitude of the correlation between the factor loadings of the dependent variable and those of the covariates, (iii) the impact of the number of moment conditions on bias and size for GMM estimators, and finally (iv) the effect of sample size. We apply each of these estimators to a crime application using a panel data set of local government authorities in New South Wales, Australia; we find that the results bear substantially different policy implications relative to those potentially derived from standard dynamic panel GMM estimators. Thus, our study may serve as a useful guide to practitioners who wish to allow for multiplicative sources of unobserved heterogeneity in their model.     

The COVID‐19 Pandemic and Families in Japan

This paper, which is authored by members of the Japanese Association of Family Therapy (JAFT), describes the COVID‐19 pandemic in Japan from a family systems perspective. The authors are active members of JAFT and include current and past presidents and officers. We describe the course of the pandemic and the ways in which government policies to mitigate the pandemic have affected Japanese families. Challenges that affect Japanese families include the inability to participate in family and social rituals, prescribed gender roles that specifically affect women, high suicide rates, and prejudice against those who are at risk of spreading the infection. The need to shelter in place has also forced family homes to function as a workplace for parents, classrooms for children, and day care services for frail elders, which has resulted in psychological distress among individuals and conflicts among families. We discuss ways that therapists have worked with Japanese families using online therapy.     

Community care for adults with severe mental disorders in rural China: A case study

In China, family care is the dominant form of care for people with mental disorders. Since 2004, the government has been developing a community‐care model that places more responsibility on community organisations and the local governments at the provincial, municipal and county levels for the provision of formal care. As a large number of people with severe mental disorders live in rural China, this case study was conducted in a rural county in order to examine the development of community care. It was found that, although family care remains dominant, families’ need for formal care is increasing. Community services have improved, but their development is constrained by several contextual and micro factors. In this study, it is argued that the community‐care model introduces a process of reconfiguration of the relative responsibility for care among the family, social organisations and the government, but progress depends on further administrative and fiscal reforms.     

Sum,product and ratio of Pareto and gamma variables

The exact distributions of X+Y, X Y and X/(X+Y) are studied when X and Y are independent Pareto and gamma random variables. Applications are discussed, to real problems in clinical trials, computer networks and economics.     

现代激进主义文化思潮中的家庭重建——以《女铎》小说中的婚姻家庭观为视角

《女铎》是创刊于1912年,停刊于1951年的一份较有影响的妇女刊物。除了宣扬基督教义,还致力于提高妇女道德及普及新知识。《女铎》发表的小说多展示普通人日常生活中的温馨,所关涉的主题多为呈现于婚姻家庭中舍己的爱,这种爱又多是经历生活的艰难及双方的摩擦后而得的,因而显得愈发可贵。其中的女性常常不是软弱无力或哀怨愁苦,而是具有自尊自立自强的人格、直面人生困境的勇气以及对家庭邻舍的责任等美德。小说呈现出对女性生命价值的尊重,以及个体生命成长与贡献社会之间的平衡意识,揭示出新女性在个人与他者、感情与事业、社会与家庭等方面的调和努力,并本着建设的目的给出解决问题的答案,因而是对现代女性争取恋爱及婚姻自由之后道路的继续探索的体现。较之那些止于冲破旧家庭的新女性的塑造之作,无疑是一种深入;较之很多新文学作品中灰暗失败的新女性生活,也是一种积极的婚姻家庭模式的建造。     

Creating the Next Wave of Family Therapy

This article is an exploration of family therapy in Australia based on interviews with seven leading Australian family therapists: Max Cornwell, Carolyn Quadrio, Ron Perry, Laurie MacKinnon, Brian Stagoll, Banu Moloney and Jim Crawley. It explores the attributes and qualities of what makes a good family therapist and seeks to understand how the next generation of therapists can generate a new enthusiasm for family therapy.
