Expected Power for the False Discovery Rate with Independence

The Benjamini–Hochberg procedure is widely used in multiple comparisons. Previous power results for this procedure have been based on simulations. This article produces theoretical expressions for expected power. To derive them, we make assumptions about the number of hypotheses being tested, which null hypotheses are true, which are false, and the distributions of the test statistics under each null and alternative. We use these assumptions to derive bounds for multiple dimensional rejection regions. With these bounds and a permanent based representation of the joint density function of the largest p-values, we use the law of total probability to derive the distribution of the total number of rejections. We derive the joint distribution of the total number of rejections and the number of rejections when the null hypothesis is true. We give an analytic expression for the expected power for a false discovery rate procedure that assumes the hypotheses are independent.     

Prometheus by the Bay: Hollywood and tech capitalism in Silicon Valley

A sequence of recent science-fiction films set in the San Francisco Bay Area suggests that Silicon Valley corporations have become a major concern for Hollywood. These films present Silicon Valley capitalism in thrall to a technological experimentation that prompts disastrous outcomes, which the films collectively argue emerges from the corporations' drive for profit and ignorance of the precautionary principle. Yet Hollywood's response to Silicon Valley involves the valorizing of a kinder, less rapacious capitalism than that of Silicon Valley, a position that prevents a thorough critique of a major challenger to its position within our culture.     

Private Pain,Public Choices: Influence of Problems in the Family of Origin on Career Choices Among a Cohort of MSW Students

This study draws on a survey of 126 graduate social work students from a large school of social work in the United States to investigate the impact of family problems on career choices. Sixty‐nine percent of the students indicated they had a family history of problems related to substance abuse (44%), psychopathology (43%), compulsive disorders (17%), and/or violence (35%). Students who report more indicators of psychopathology and violence were more likely to see their family history as influential in their career choice. These students were also more likely to select mental health/health as a practice area. However, no differences were found between students without a family history of problems and those who did not see their family history as influential. Students' history of family problems and their perceptions of its influence on career choice did not affect the likelihood of selecting a practice method. The authors discuss the implications of these findings and conclude with a series of recommendations for social work education.     

Environmental and Policy Change to Support Healthy Aging

Given the growing evidence of the influence of the environment on older adult health, the need to design and implement effective environmental policy around healthy and vital aging is urgent. This article describes issues amenable to improvement through policy change, evidence supporting specific policy approaches and outcomes, and promising strategies for implementing those approaches. Key areas of focus are neighborhood design and safety, housing, transportation, and mobility. Strategies to build capacity for policy change are also addressed. Our goals are to foster greater attention to environmental change in support of healthy aging and to illuminate directions for policy change.     

Place,identity and football: Catalonia,Catalanisme and Football Club Barcelona, 1899–1975

A growing body of work considers sport and the social construction of identities. Drawing from that research, this article considers how football clubs are involved in the construction of national identities by making explicit the connections between sport, identity and place. The first part of the article examines the literature addressing sport and collective identification/representation and considers critical approaches that uncover the power relations that frame the sport/identity nexus. The second part of the article applies these ideas to a discussion of Football Club Barcelona's role in the social construction of Catalan nationalism and national identity from 1899 to 1975.     

Children's perceptions of playfighting, playchasing and real fighting: a cross-national interview study

Playfighting and chasing can he distinguished from real fighting, hut their significance in children's development remains uncertain. This study examines playfighting and chasing from the child's, rather than the observer's, perspective, using a questionnaire given to 8 and 11 year olds in England and South Italy and 5 year olds in England. Findings were generally similar for English and Italian children. Most hoys and girls reported both liking, and taking part in, playchasing; liking and participation in playfighting was more divided, though more so for boys, with many children disliking the perceived risk of injury in playfighting. About half the children (more boys than girls) reported having been in a serious fight, often provoked by verbal abuse or accidental injury. Most children reported that they could tell playfighting from a serious fight; at 5 years, liking and taking part in playfights was a predictor of this ability, which approached ceiling by 8 and 10 years. A wide variety of cues were given which could distinguish playful and serious fighting. Findings were consistent with the practice hypothesis for playfighting. However, most children also thought that playfighting could lead to a serious fight, especially as a result of accidental injury; escalation of this kind was also thought to be more likely if the play partner was not a best friend. Both ‘honest mistakes’ and ‘cheating’ seem to be possible explanations for playfighting leading to serious fighting. Assertion or maintenance of dominance may be a function for cheating in playfighting.     

Street Traffic,Social Integration,and Fear of Crime*

Drawing on the work of Jacobs, Newman, and Gardiner, among others, this paper investigates fear of crime by urban residents as a consequence of two interrelated characteristics of neighborhoods: 1) the perceived volume of street usage and 2) the degree of residents' social integration into the neighborhood. Secondary analysis of a 1975 survey shows that, counter to previous hypotheses, perception of increased street traffic leads to greater fear. However, when controlling for social integration, we find that for those who are socially integrated perceived volume of street traffic has no relationship to fear, while for those not socially integrated the greater the perceived street usage the greater the fear. Three mechanisms by which social integration may reduce fear of people on the streets are considered: 1) reducing the proportion of strangers versus acquaintances on the street; 2) providing networks of potential assistance; and 3) reducing the strangeness of the streets' daily rhythms and routines. We conclude that both physical design and social factors must be interrelated in attempts to understand fear of crime and in designing ameliorative programs.     

Simple measures of progress and outcome in the evaluation of mental health services.

There is a tautology regarding the use of progress and outcome measures. Such measures are easy to use in a reliable and valid fashion if the language of the measures is used as an integral part of (a) treatment planning and progress review, (b) clinical supervision, and (c) program management. The paper describes example guidelines and uses of measures in each of these functions. Also included are listings of scales with documented reliability and validity (by target population) and some sources for finding computer software for scoring some of the scales.     

Gambling and other risk behaviors on university campuses

To examine the prevalence of problem gambling and its relationship to other risk-taking behaviors, the authors surveyed 1,350 undergraduates at the 4 campuses of Connecticut State University (CSU) during fall 2000. On the basis of a modified version of the South Oaks Gambling Screen, a widely used screening instrument, they found that 18% of the men and 4% of the women reported that gambling had led to at least 3 negative life consequences (eg, felt guilty, gambled more than intended), commonly defined as problem gambling. Students identified as problem gamblers, compared with other students, were significantly more likely to be heavy drinkers, report negative consequences of alcohol consumption, and be regular tobacco and marijuana users. Problem gambling was related to binge eating and greater use of weight-control efforts. University athletes were also found to have significantly greater problem gambling rates than nonathletes. The majority of students gambled but experienced few of the negative consequences reported by problem gamblers.
