The Children First Program: The Effectiveness of a Parent Education Program for Divorcing Parents

This study evaluated the effectiveness of the 2nd and 3rd editions of the Children First parent education programs for parents experiencing divorce or separation. Participants were 678 parents experiencing separation or divorce in 2 Midwestern counties. Changes from pretest to posttest on participants’ knowledge, attitudes, and likelihood of adaptive coparenting were assessed. Both editions of the program had a significant positive effect on all 3 measures of adaptive coparenting. The effect sizes from pretest to posttest for the 2nd edition were small, whereas the effect sizes for the 3rd edition of the program were nearly twice as large. Superiority of the 3rd edition might be due to an increased focus on explicit training on adaptive coparenting behaviors.     

Irish Women’s Ongoing Experiences of Domestic Abuse in Cases of Separation and Divorce

The issue of postseparation abuse is a significant problem for women. This qualitative research examines Irish women’s experiences of domestic abuse in cases of separation and divorce. Findings show that methods of abuse change after separation and perpetrators can use institutions of the state to continue their abusive behavior in a new forum and can continue long after marital dissolution is finalized. Such behavior is legitimized by the state’s nonaction and enabled through women’s previous experiences of institutional processes associated with separation and divorce, which resulted in feelings fear and distress.     

Parent–child gender matching and child psychological adjustment after divorce

The present study aimed to determine whether a parent–child gender match would influence child psychological adjustment after divorce. Participants included 69 parents (36 mothers) in active family law litigation to resolve issues related to postdissolution of marriage or time-sharing matters. Participants provided demographic information and completed the Child Behavior Checklist (CBCL; Achenbach, 1991 Achenbach, T. M. (1991). Manual for the child behavior checklist/4–18 and 1991 profile. Burlington, VT: Department of Psychiatry, University of Vermont. [Google Scholar]) to assess their perceptions of their child’s internalizing and externalizing behavior problems. Results demonstrated that internalizing and externalizing behaviors were not affected by whether children spent more time with the same gender parent, opposite gender parent, or split their time equally between both. Comparisons and contradictions between the results in this study and existing research are discussed, as well as practical implications.     

Minimum variance unbiased estimation of stress–strength reliability under bivariate normal and its comparisons

In many industrial and natural phenomena, we need the probability that a component is smaller than the other component. Under a stress–strength model, this is reliability of an item. Under independent setup, there are different approaches for the estimation of such reliability. Here, estimation is considered under the dependent case. Under bi-variate setup uniformly minimum variance unbiased estimator is obtained. Also comparison with available estimator based on Maximum Likelihood Estimate (MLE) is done through Mean Square Error (MSE) and bias. Also these are compared by computing L₁ distance between their distribution functions. From this idea and numerical computations, UMVUE appears to be good.     

Separations: A Personal Account of Bowen Family Systems Theory

This paper is a personal account of my own family of origin research. It explores the impact of separations from parents, nuclear family, and extended family through a Bowen family systems theory perspective using concepts pertaining to Bowen theory such as chronic anxiety, differentiation of self, multigenerational family process, and the emotional system. An outline of the process of doing research in ‘vivo’ with my mother as well as conversations with my supervisor are included. Theoretical differences between individual and system models are discussed. A Bowen theoretical approach to the anxiety of separations is investigated. The efficacy of engaging in family of origin work and the effects of thinking systems is examined in light of how it assisted me to view family members, family system disturbances, and clients’ emotional systems more objectively.     

A probabilistic approach to Wallis’ formula

We present an alternative proof of Wallis’ formula from the probabilistic point of view. Based on the classical central limit theorem, some discrete distributions with additive property, such as binomial, negative binomial, Poisson and multinomial distributions, are considered to derive π/2.     

A simple approximation for the doubly noncentral t-distribution

A simple approximation for the doubly noncentral t-distribution, based upon the Fieller-Geary Theorem (1930) and approximate normality of the square root of the noncentral chi-square variable observed by Patnaik (1949), is developed, This approximation and an Edgeworth series expansion associated with it are evaluated. The simple approximation is seen to be reasonably accurate for most practical purposes.     

A process capability index with reliable confidence intervals

A well-know process capability index is slightly modified in this article to provide a new measure of process capability which takes account of the process location and variability, and for which point estimator and confidence intervals do exist that are insensitive to departures from the assumption of normal variability. Two examples of applications based on real data are presented.     

Proportional Trapping-Removal Model with a Known Ratio

ABSTRACT

Population size estimator is derived for a proportional trapping-removal model with a known ratio between two sub-population sizes, and the corresponding asymptotic properties is obtained. The performance of the proposed estimator is checked via simulation studies and an example.
