Acceptance and Caregiving of Married and Divorced Custodial Mothers and Fathers

The study examined whether differences in gender and family status affect parental caregiving disposition and acceptance of children among parents of children in mid-childhood. The number of participants were 122 divorced-custodial fathers, 107 married fathers, 85 divorced-custodial mothers, and 82 married mothers (n?=?398). A comparison among four groups of parents revealed the following gender differences: mothers scored higher on anxious caregiving and parental acceptance than fathers, and lower on avoidant caregiving. Regression analysis indicated that the higher the caregiving avoidance or anxiety, the lower the parental acceptance. Family status moderated parental acceptance, as avoidant caregiving was associated with reduced parental acceptance among married parents, but not among divorced custodial parents. The finding that avoidant caregiving was not associated with reduced acceptance among divorced custodial parents implies that their parental acceptance behaviors toward their children are affected by their parental status as sole custodial parent, and the associated responsibilities, rather than by gender.     

The competing risks analysis for parallel and series systems using Type-II progressive censoring

Abstract

Recently, the study of the lifetime of systems in reliability and survival analysis in the presence of several causes of failure (competing risks) has attracted attention in the literature. In this paper, series and parallel systems with exponential lifetime for each item of the system are considered. Several causes of failure independently affect lifetime distributions and observations of failure times of the systems are considered under progressive Type-II censored scheme. For series systems, the maximum likelihood estimates of parameters are computed and confidence intervals for parameters of the model are obtained using Fisher information matrix. For parallel systems, the generalized EM algorithm which uses the Newton-Raphson algorithm inside the EM algorithm is used to compute the maximum likelihood estimates of parameters. Also, the standard errors of the maximum likelihood estimates are computed by using the supplemented EM algorithm. The simulation study confirms the good performance of the introduced approach.     

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.     

A court file analysis of child protection cases: What do children say?

Children's participation in legal proceedings affecting them personally has been gaining importance. So far, a primary research concern has been how children experience their participation in court proceedings. However, little is known about the child's voice itself: Are children able to clearly express their wishes, and if so, what do they say in child protection cases? In this study, we extracted information about children's statements from court file data of 220 child protection cases in Germany. We found 182 children were asked about their wishes. The majority of the statements found came either from reports of the guardians ad litem or from judicial records of the child hearings. Using content analysis, three main aspects of the statements were extracted: wishes concerning main place of residence, wishes about whom to have or not contact with, and children granting decision‐making authority to someone else. Children's main focus was on their parents, but others (e.g., relatives and foster care providers) were also mentioned. Intercoder agreement was substantial. Making sure that child hearings are as informative as possible is in the child's best interest. Therefore, the categories developed herein might help professionals to ask questions more precisely relevant to the child.     

The exponential distribution analog of the Grubbs–Weaver method

Abstract

Grubbs and Weaver (1947 Grubbs, F. E., and C. L. Weaver. 1947. The best unbiased estimate of population standard deviation based on group ranges. Journal of the American Statistical Association 42 (238):224–41. doi: 10.2307/2280652.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) suggest a minimum-variance unbiased estimator for the population standard deviation of a normal random variable, where a random sample is drawn and a weighted sum of the ranges of subsamples is calculated. The optimal choice involves using as many subsamples of size eight as possible. They verified their results numerically for samples of size up to 100, and conjectured that their “rule of eights” is valid for all sample sizes. Here we examine the analogous problem where the underlying distribution is exponential and find that a “rule of fours” yields optimality and prove the result rigorously.     

Bounded risk estimation of a linear combination of location parameters in negative exponential distributions via three-stage sampling

The paper deals with the problem of bounded risk point estimation for a linear combination of location parameters of two negative exponential distributions. Isogai and Futschik considered the situation when the location and scale parameters are all unknown. They proposed purely sequential procedures and gave second order expansions of the average sample sizes and risks. In this paper we propose three-stage procedures and derive second order expansions of the average sample sizes and risks. Further, we compare the results with those from previous work.
