Estimation in a Multivariable Two-Phase Regression

A likelihood approach is considered for the problems of estimating the changepoint and other parameters in a multivariable two-phase regression.Methods for finding the maximum likelihood estimates are given for the cases when the covariance matrix is known, and unknown.The distribution of the usual likelihood ratio test statistic is Investigated using simulations, and a Monte-Carlo aporoach is suggested for testing for the existence of a change-point.Numerical1 Illistrute aie provided.     

Characterizing Mother’s Dating After Divorce

Mothers dating after divorce is a dynamic process, where not all mothers date the same way after divorce. However, few studies have examined the different ways that mothers date after divorce, which should influence maternal well-being, risk behaviors, and the quality of their relationships. This study characterizes four different approaches to mothers’ repartnering (referred to as repartnering histories): no dating, dating one partner monogamously, dating multiple partners serially, and dating multiple partners simultaneously. Each repartnering history is characterized by demographic variables, relationship quality, and maternal well-being. Implications of the study are discussed.     

Shame and pride in second-generation German identity in Melbourne,Australia: emotions and white ethnicity

As members of an established, well-integrated, white ethnic group, second-generation Germans are largely invisible in Australian society. Given this, they are easily presumed a group for whom Gans’ notion of ‘symbolic ethnicity’ might apply. However, based on interviews with adult children of German immigrants in Melbourne, Australia, this article suggests an alternative interpretation using recent literature on the role of emotions for identity. In the interviews with adult children of German immigrants in Melbourne, Australia, the notions of shame and pride in relation to ethnic identity were clearly evident. Shame often emerged in interaction with other people in Australia, and particularly in relation to Nazism and the Second World War. However, most respondents felt equally proud of their German heritage, particularly later in life. These findings suggest that ethnic identity for these second-generation Germans is a deeper, embodied experience that is similar to what Bourdieu terms habitus.     

EXPLORING A FOURTH DIMENSION: SPIRITUALITY AS A RESOURCE FOR THE COUPLE THERAPIST

This article explores ways in which the therapist's own spirituality can serve as a resource in couple therapy. Spirituality is defined as subjective engagement with a fourth, transcendent dimension of human experience. This engagement enhances human life and evokes corresponding behavior. Spiritually based therapy may be influenced by three assumptions: that God or a Divine Being exists, that human-kind yearns innately for connection with this Being, and that this Being is interested in humans and acts upon and within their relationships to promote beneficial change. In therapy these assumptions affect how the therapist listens and responds throughout sessions. The authors incorporate a case example illustrating the application of this fourth dimension in couple therapy.     

Maximum-likelihood estimates and likelihood-ratio criteria for multivariate elliptically contoured distributions

For a class of multivariate elliptically contoured distributions the maximum-likelihood estimators of the mean vector and covariance matrix are found under certain conditions. Likelihood-ratio criteria are obtained for a class of null hypotheses. These have the same form as in the normal case.     

Court-ordered foster family care reform: a case study

The authors examine the implications of G. L. v. Zumwalt, a case that resulted in a far-reaching consent decree that mandates specific reforms in policy and practice to be implemented by a public social welfare agency in its delivery of services to foster children and their families.
