The Effectiveness of an Attachment-focused Treatment Model in a Therapeutic Preschool for Abused Children

Child maltreatment is associated with detrimental developmental effects. In view of the fact that child maltreatment typically occurs within the context of a caretaking relationship, attachment theory can give us insight into the nature of difficulties experienced by survivors. Therapeutic preschool has been found effective in addressing developmental problems in abused children. This study examines the effectiveness of an attachment-based therapeutic preschool for maltreated children. Means tests indicate that, at the time of discharge, the children being served had made significant overall developmental gains as well as significant gains in the personal–social and adaptive domains of development.     

Regression Models and Risk Estimation for Mixed Discrete and Continuous Outcomes in Developmental Toxicology

Multivariate dose-response models have recently been proposed for developmental toxicity data to simultaneously model malformation incidence (a binary outcome), and reductions in fetal weight (a continuous outcome). In this and other applications, the binary outcome often represents a dichotomization of another outcome or a composite of outcomes, which facilitates analysis. For example, in Segment II developmental toxicology studies, multiple malformation types (i.e., external, visceral, skeletal) are evaluated on each fetus; malformation status may also be ordinally measured (e.g., normal, signs of variation, full malformation). A model is proposed is for fetal weight and multiple malformation variables measured on an ordinal scale, where the correlations between the outcomes and between the offspring within a litter are taken into account. Fully specifying the joint distribution of outcomes within a litter is avoided by specifying only the distribution of the multivariate outcome for each fetus and using generalized estimating equation methodology to account for correlations due to litter clustering. The correlations between the outcomes are required to characterize joint risk to the fetus, and are therefore a focus of inference. Dose-response models and their application to quantitative risk assessment are illustrated using data from a recent developmental toxicology experiment of ethylene oxide in mice.     

Spillover in the Home: The Effects of Family Conflict on Parents' Behavior

Conflict with a spouse or child may generate spillover, defined as short‐term affective changes in parents that affect their behavior with other family members. In a diverse sample of 86 parents, this 56‐day diary study examined daily bidirectional spillover between conflict in the marital or parent–child dyad and parents' irritable, frictional behavior with their child or spouse, respectively. Tests of daily associations between conflict and parent behavior revealed robust spillover effects according to parent as well as spouse and child reports. Parents' daily negative mood and child externalizing behavior contributed to several but not all of these associations. Daily spillover findings were largely unaffected by parents' neuroticism, suggesting that parents' day‐to‐day fluctuations in negative mood, not average levels of negative affectivity, promoted spillover. Significant direct effects of conflict on parent behavior even when controlling for negative mood, however, implicate additional cognitive or social processes as contributors to conflict spillover in families.     

Dynamic Pricing and Demand Estimation for a Single Unique Asset*

We address the situation of a firm that needs to dispose of a large, expensive asset (e.g., car, machine tool, earth mover, turbine, house, airplane), with or without a given deadline (and either known or unknown to the buyer). If a deadline exists, the asset is salvaged at a known value which may be zero, or even negative if there is a disposal cost. The asset has a known holding cost and may also have an initial nominal (undiscounted) price. The question is how, if at all, the price should be discounted as time progresses to maximize the expected proceeds. We use a dynamic recursion where each decision stage can be optimized based on classic economic monopoly pricing theory with a demand intensity function estimated from sales data, and show that the model is well‐behaved in the sense that the optimal price and optimal expected revenue monotonically decline as the deadline approaches. We test the model by comparing its optimal price pattern to the official pricing policy practiced at a used‐car dealer. We then extend the model to situations where the buyer knows the seller's deadline and thus may alter his behavior as the deadline approaches.     

The careful balance of gender and sexuality: rural gay men, the heterosexual matrix, and "effeminophobia"

Based on life narratives, this article explores rural gay men's subjectivity in France and the United States. After growing up in rural cultures, these gay men tend to adopt similar hetero-centered ideas about masculinity. We show that these "conventional" ideas impact their sense of self as they express feelings of "effeminophobia." They differentiate themselves from effeminate gay men and emphasize their similarities with straight men. These ideas are both coercive and disciplinary as they homogenize rural gay men's discourse and masculine identities.     

Knowledge dissemination in operations management: Published perceptions versus academic reality

The channels for knowledge generation and dissemination in the business disciplines are many: presenting research at conferences, writing books, distributing working papers, offering insights in society newsletters, giving invited talks, publishing studies in academic journals, and many other venues, including even blogs and perhaps Facebook^®. But the most important venue is probably published research in “top-level” academic journals. In the discipline of Operations Management, many studies and lists have been published that attempt to determine which of these journals are supposedly the “top” according to either citation analyses, the opinion of recognized experts, author affiliations, bibliometric studies, and other approaches. These lists may then, in turn, be used in different degrees to evaluate research. However, what really counts is what the academic institutions actually use for guidance in evaluating faculty research. Based on a new source of ranking data from AACSB-accredited schools, we compare published journal-ranking studies against that of academe to determine the degree to which the studies reflect academic “reality”. We present rankings of OM journals based on this new source of data and on an aggregate of the stream of published studies, and evaluate their consistency.     

The indirect effect of perceived burdensomeness on the relationship between indices of social support and suicide ideation in college students

Objective: Research has demonstrated that a lack of social support is related to suicide risk. This study examines perceived burdensomeness and thwarted belongingness, of the Interpersonal Theory of Suicide, as mechanisms of the social support–suicide relationship in college students. Method: The study consisted of 207 students from a Midwestern university. Data were collected from 2007 to 2008. Two multiple mediation analyses were conducted to examine whether perceived burdensomeness and thwarted belongingness mediated the relationship between indices of social support and suicide ideation. Results: Perceived burdensomeness mediated the relationships between perceived social support and suicide ideation (95% confidence interval [CI] ?.02 to ?.00, effect size = ?.01) and social connectedness and suicide ideation (95% CI ?.03 to ?.00, effect size = ?.03). Thwarted belongingness did not mediate either relationship. Conclusions: Results suggest that a lack of social support could lead to perceptions of being a burden on others, which could lead to suicide ideation.     

Preparing social workers for ecosocial work practice and community building

ABSTRACT

In the context of the global ecological crisis, the profession of social work is increasingly shifting to embrace an ecosocial lens, recognizing the centrality of the ecological environment for human existence and the inextricable linkages of wellbeing for people and planet. Social work educators are contributing to this shift as leaders in the transformation of their home institutions and communities. We present examples within two models of education for ecosocial work, the infusion model and the integration model. Exemplars are based on the authors’ expertise and contributions to ecosocial work education, community building, and ecosocial change, both locally and globally.
