Eating and Exercise Disorders in Young College Men

Abstract

The authors used the computerized Eating and Exercise Examination to investigate eating, weight, shape and exercise behaviors in a convenience sample of 93 male college students. One fifth of the men worried about their weight and shape, followed rules about eating, and limited their food intake. Between 9% and 12% were unhappy with their body shape, felt fat, and seriously wanted to lose weight. Exercise was important for the self-esteem of 48% of the students. Thirty-four percent were distressed when they could not exercise as much as they wanted, 27% followed rules about exercising, and 14% worried about the amount of exercise they were doing. The respondents met clinical diagnoses for objective binge eating (3%), self-induced vomiting (3%), bulimia nervosa (2%), and exercise disorders (8%). Although 9% reported disordered eating, none had sought treatment. Health professionals should be aware that eating and exercise disorders may be present in college men and that screening may help in the early identification of these problems.     

Influence of Prenatal Mercury Exposure Upon Scholastic and Psychological Test Performance: Benchmark Analysis of a New Zealand Cohort

This paper presents benchmark (BMD) calculations and additional regression analyses of data from a study in which scores from 26 scholastic and psychological tests administered to 237 6- and 7-year-old New Zealand children were correlated with the mercury concentration in their mothers' hair during pregnancy. The original analyses of five test scores found an association between high prenatal mercury exposure and decreased test performance, using category variables for mercury exposure. Our regression analyses, which utilized the actual hair mercury level, did not find significant associations between mercury and children's test scores. However, this finding was highly influenced by a single child whose mother's mercury hair level (86 mgkg) was more than four times that of any other mother. When that child was omitted, results were more indicative of a mercury effect and scores on six tests were significantly associated with the mothers' hair mercury level. BMDs calculated from five tests ranged from 32 to 73 mgkg hair mercury, and corresponding BMDLs (95% lower limits on BMDs) ranged from 17 to 24 mgkg. When the child with the highest mercury level was omitted, BMDs ranged from 13 to 21 mgkg, and corresponding BMDLs ranged from 7.4 to 10 mgkg.     

Using partially observed Markov processes to select optimal termination time of TV shows

This paper presents a method for optimal control of a running television show. The problem is formulated as a partially observed Markov decision process (POMDP). A show can be in a “good” state, i.e., it should be continued, or it can be in a “bad” state and therefore it should be changed. The ratings of a show are modeled as a stochastic process that depends on the show's state. An optimal rule for a continue/change decision, which maximizes the expected present value of profits from selling advertising time, is expressed in terms of the prior probability of the show being in the good state. The optimal rule depends on the size of the investment in changing a show, the difference in revenues between a “good” and a “bad” show and the number of time periods remaining until the end of the planning horizon. The application of the method is illustrated with simulated ratings as well as real data.     

The once and future crisis

The insurance crisis of the mid-1980s produced a number of legal and public policy reactions. Although many of the immediate symptoms of that crisis have disappeared, a number of its underlying causes remain. This article analyzes the continuing effect of these factors on the insurance markets, and predicts the occurrence of a milder crisis during the mid-1990s.     

The emerging self in conceptualizing and treating mental illness

1. The course of severe mental illnesses is more heterogeneous than previously thought and is influenced by many complex, interacting factors. 2. The experience of self and capacity to cope of people with mental illnesses contribute to the recovery process. 3. Changes in traditional treatment models and a focus on broader societal interventions are needed to facilitate recovery. 4. Psychiatric nurses play an important role in these new developments as evident, for example, in the 3R Program (relapse, recovery, and rehabilitation).     

Practical problems associated with programme evaluation in third world countries

Problems in conducting programme evaluation in third world countries can be divided into four interrelated categories: those associated with design, personnel, time, and budget. Some of the problems in each of these areas are considered and suggestions for dealing with them are presented.     

Isolation as a Form of Marital Violence: The South Asian Immigrant Experience1

Isolation is an important factor in marital abuse among South Asian immigrant families. It lends itself to the invisibility immigrant women experience based on their ethno-gender status in the United States. Drawnfrom unstructured interviews with abused South Asian immigrant women, three different levels of isolation are explained. The first level involves the quality of a woman’s relationship with her spouse; the second is related to thefrequency and quality of social interaction with friends, relatives, and coworkers; and the third is explained in terms of the level of access to and participation in the ethnic community and other formal institutions.     

Linking Perceived External Prestige and Intentions to Leave the Organization: The Mediating Role of Job Satisfaction and Affective Commitment

ABSTRACT

The present study examines social workers' beliefs about the prestige that outsiders (e.g., patients, suppliers, competitors, and the public) attribute to their organization and the way these beliefs influence the social workers' commitment to the organization they work for, job satisfaction, and turnover intentions (i.e., intentions to leave the organization). We collected two primary data sets (N = 160 and N = 489, respectively) from social workers in nonprofit social service organizations in Israel in 2001 and 2002. In general, the results show that perceived (construed) external prestige results in higher employee commitment and satisfaction, which, in turn, leads to lower levels of intention to leave the organization. The implications of these findings for research on organizational image and employee commitment are discussed, with particular emphasis on social workers in nonprofit social service organizations.     

Indicators of family resilience after the death of a child

The aim of this study was to identify and describe resilience qualities in families after losing a child. Questionnaires, including an open-ended question, were utilized to collect data independently from the parents and siblings of the deceased in 89 Belgian families. The results indicate that family strengths in general, and commitment to the family in particular, helped the families' adaptation after the loss. In addition, the adaptation process after the loss was aided if the family members viewed the crisis as a challenge. Both the siblings and the parents indicated that the extent to which a family experienced support from the community was directly related to family adaptation after the loss. Redefining the situation and utilizing social support from friends and family were underlined as effective family coping strategies. The findings could be used in interventions to promote family resilience, thereby affirming the reparative potential of families.
