The association between mood states and physical activity in postmenopausal, obese, sedentary women

Mood states influence evaluative judgments that can affect the decision to exercise or to continue to exercise. This study examined how mood associated with graded exercise testing (GXT) in sedentary, obese, postmenopausal women (N = 25) was associated with physical activity and predicted VO2max during and after a behavioral weight-loss program (BWLP). Measures of physical activity included planned exercise, calories from physical activity, leisure-time physical activity, and predicted VO2max. Mood before and after pre-BWLP GXT was assessed using the Profile of Mood States. Mood before and after the GXT was more strongly associated with planned exercise than other forms of physical activity, and this effect became stronger over time. Mood enhancement in response to exercise was not related to physical activity. Mood before and after exercise might yield important clinical information that can be used to promote physical activity in sedentary adults.     

THE CARING DILEMMA IN MIDWIFERY

The caring dilemma, first described by Reverby in 1987, denotes the tension caused by being obliged to provide care without the right to determine how that care is to be provided. Such a dilemma is salient in the practice of midwifery based on a continuity of care model that has recently emerged or been implemented in various jurisdictions. Briefly, this model involves the provision of care by a single midwife or pair of midwives to a woman throughout her pregnancy, birth and post-natal period. Continuity of care necessitates that midwives be on call for significant lengths of time to ensure attendance at the woman's birth. It is the on-call nature of this form of midwifery work that most significantly poses a caring dilemma for midwives. In this paper, we trace both the structural and experiential aspects of the caring dilemma through an examination of midwifery in the Canadian province of Ontario. Our analysis reveals that despite being a salient feature of midwifery practice, some work structures can be created to mediate the caring dilemma experienced by midwives.

Le dilemme de la prise en charge, que Reverby a évoqué la première fois en 1987, dénote la tension que cause le fait d’être tenu d'offrir une prise en charge sans avoir le droit d’établir de quelle manière l'offrir. L'exemple des sages-femmes, dont la pratique repose sur un type de soin continu qui est récemment apparu ou qu'on vient de mettre sur pied dans diverses administrations, illustre très clairement ce dilemme. Pour résumer, ce modèle veut qu'une femme enceinte soit prise en charge pendant sa grossesse, à son accouchement et durant sa période postnatale par une ou deux sages-femmes. La continuité de la prise en charge oblige les sages-femmes à être sur appel durant des périodes prolongées pour que la femme qui accouche bénéficie de leur présence. Pour les sages-femmes, c'est la nature même de leur travail effectué sur appel qui engendre, de façon cruciale, le dilemme de la prise en charge. Dans cet article, nous abordons les aspects structurels et expérimentaux que représente le dilemme de la prise en charge par le biais d'une étude sur la pratique du métier de sage-femme dans la province canadienne de l'Ontario. Notre analyse révèle que, si le dilemme de la prise en charge est inhérent à la profession de sage-femme, il n'empêche que des structures professionnelles peuvent être mises en place pour en atténuer les aspects négatifs.     

Sampling hyperparameters in hierarchical models: Improving on Gibbs for high-dimensional latent fields and large datasets

ABSTRACT

A common Bayesian hierarchical model is where high-dimensional observed data depend on high-dimensional latent variables that, in turn, depend on relatively few hyperparameters. When the full conditional distribution over latent variables has a known form, general MCMC sampling need only be performed on the low-dimensional marginal posterior distribution over hyperparameters. This improves on popular Gibbs sampling that computes over the full space. Sampling the marginal posterior over hyperparameters exhibits good scaling of compute cost with data size, particularly when that distribution depends on a low-dimensional sufficient statistic.     

THE PARENTING EXPERIENCES OF MOTHERS WITH DISSOCIATIVE DISORDERS

This article presents a qualitative analysis of the experience of parenting of mothers with dissociative disorders. This analysis was performed to complement the quantitative analysis of problems of mothers with dissociative disorders that Benjamin, Benjamin, and Rind (1996) presented previously. They found that the functioning of these mothers, as well as their subjective experience of mothering, was poorer that that of either clinical or nonclinical control mothers. Our goal was to provide a clearer, richer picture of their problems in parenting. Using the mothers' own words, we describe how the five symptom areas of dissociation (amnesia, depersonalization, derealization, identity confusion, and identity alteration) impeded their parenting efforts. We conclude with a discussion of the necessity of addressing parenting in the treatment of client-mothers with dissociative disorders.     

THE INTERACTION BETWEEN MARITAL STANDARDS AND COMMUNICATION PATTERNS: HOW DOES IT CONTRIBUTE TO MARITAL ADJUSTMENT?

Couples' cognitions about marriage and their communication patterns have both been found to be highly associated with marital distress. To examine the relationships among marital cognitions, communication, and marital adjustment, we had a sample of 387 community couples complete three self-report measures: the Dyadic Adjustment Scale, the Inventory of Specific Relationship Standards, and the Communication Patterns Questionnaire. Results indicated that the correlation of communication with marital adjustment is higher for women with more relationship-focused standards than for women with less relationship-focused standards; this interaction does not occur for men. The implications of the interaction and the gender difference as well as the importance of teaching communication skills, and working with associated cognitions are discussed.     

The American Stop Smoking Intervention Study. Conceptual framework and evaluation design.

Reducing tobacco use, especially cigarette smoking, is a public health priority. The American Stop Smoking Intervention Study (ASSIST) was initiated in 1991 to prevent and reduce tobacco use primarily through policy-based approaches to alter the social-political environment. This article describes the conceptual design, research framework, evaluation components, and analytic strategies that are guiding the evaluation of this demonstration research endeavor. The ASSIST evaluation is a unique analysis of the complex relationships between the social context, public health activity at the state level, tobacco use, and individual behavior. The measures of tobacco control activity developed for this evaluation may be useful in ongoing national cancer control surveillance efforts, and the lessons learned will enhance the development of tobacco control programs.     

What motivates adolescent bystanders to intervene when immigrant youth are bullied?

Pathways to bystander responses were examined in both generalized and bias-based bullying incidents involving immigrant-origin victims. Participants were 168 (M_age = 14.54, 57% female) adolescents of immigrant (37.5%) and nonimmigrant backgrounds, who responded to their likelihood of intervening on behalf of either an Arab or Latine victim. Models tested whether contact with immigrants and one's desires for social contact with immigrant-origin peers mediated the effects of individual (shared immigrant background, and discriminatory tendencies) and situational (inclusive peer norms) intergroup factors on active bystander responses. Findings indicated that desires for social contact reliably mediated effects across both victims; however, contact with immigrant peers was only associated with responses to Latine victims. Implications for how to promote bystander intervention are discussed.     

“Families” in International Context: Comparing Institutional Effects Across Western Societies

We review comparative evidence of institutional effects on families in Western societies. We focus on 2 key aspects of family life: gendered divisions of labor and people's transitions into, within, and out of relationships. Many individual‐level models assume the effects are robust across countries. The international evidence over the past decade suggests instead that the socioeconomic and policy contexts strongly influence the significance and even direction of individual effects. A growing body of evidence also highlights important differences across social groups and family forms within countries. The pattern of relative gender, class, and other group equality varies across countries, as do related family experiences and outcomes. We conclude with suggestions for future comparative family research.     

The social transformation of American medical education: class, status, and party influences on occupational closure, 1902–1919

Applying Weber's theorizing on action and stratification, this study examines whether the early 20th-century extinction of half of the medical schools in the United States resulted from actions intended to serve class, status, and party interests by achieving social closure. Analyses reveal closure intentions in the school ratings assigned by the American Medical Association, although not in the recommendations in the 1910 Carnegie-sponsored Flexner report. In contrast to claims that schools failed largely because of economic exigencies, analyses indicate that failures were influenced by the AMA's and Flexner's assessments, as well as by state regulatory regimes and school characteristics.
