With over 1 million children in the United States affected by parental divorce or separation each year, there is interest in interventions to mitigate the potential negative consequences of divorce on children. Family mediation has been widely heralded as a better solution than litigation; however, mediation does not work for all families. One proposed improvement involves bringing the child’s ...

A key aim of social psychology is to understand the psychological processes through which independent variables affect dependent variables in the social domain. This objective has given rise to statistical methods for mediation analysis. In mediation analysis, the significance of the relationship between the independent and dependent variables has been integral in theory testing, being used as ...

Research has consistently shown that males play violent video games more frequently than females, but factors underlying this gender gap have not been examined to date. The present approach examines the assumption that males play violent video games more, because they anticipate more enjoyment and less guilt from engaging in virtual violence than females. This may be because males are less empa...

a hydroethanolic extract (he-ext) of bacopa monnieri (bm) was studied for antinociceptive effect in the animal models of acetic-acid-induced writhing test and antilocomotive effect in mice. standard centrally-acting analgesic, morphine (mp), and peripherally-acting one, diclofenac (diclo), were also tested along with the extract for comparison. the extract exhibited significant antinociceptive ...

The Equal Employment Opportunity Commission (EEOC) has experienced dramatic backlogs of pending charges over the years. In 1977, the backlog reached an all-time high of 130,000 cases pending. Recently, the EEOC announced that the backlog had been reduced to 29,890 cases. A significant portion of this reduction is attributab le to an increased use of mediation. During FY 2001, 7,800 of the 94,59...

We conduct principal stratification and mediation analysis to investigate to what extent the positive overall effect of treatment on postoperative pain control is mediated by postoperative self administration of intra-venous analgesia by patients in a prospective, randomized, double-blind study. Using the Bayesian approach for inference, we estimate both associative and dissociative principal s...

Mediation does not only mean a specific procedure or protocol but the related attitude, mindset as well. This perspective gives opportunity to demonstrate the problem in a different way than previously. In the present study the participatory theory of communication (PTC) appears as a framework which makes the communication of participants of the mediation interpretable and transparent.

Mediation analysis is often based on fitting two models, one including and another excluding a potential mediator, and subsequently quantify the mediated effects by combining parameter estimates from these two models. Standard errors of such derived parameters may be approximated using the delta method. For a study evaluating a treatment effect on visual acuity, a binary outcome, we demonstrate...

Motivated by recent advances in causal inference on mediation analysis and problems in the analysis of metagenomic data, we consider the effect of a treatment on an outcome transmitted through microbes, or compositional mediators. Compositional and high dimensional natures of such mediators make the standard mediation analysis not directly applicable. In this paper, we propose a method for esti...
