A stepwise algorithm for selecting category boundaries for the chi-squared goodness-of-fit test

A stepwise algorithm for selecting categories for the chisquared goodness-of-fit test with completely specified continuous null and alternative distributions is described in this paper. The procedure's starting point is an initial partitioning of the sample space into a large number of categories. A second partition with one fewer category is constructed by combining two categories of the original partition. The procedure continues until there are only two categories; the partition in the sequence with the highest estimated power is the one chosen. For illustartive purposes, the performance of the algorithm is evaluated for several hypothesis tests of the from H₀: normal distribution vs. H₁: a specific mixed normal distribution. For each test considered, the partition identified by the algorithm was compared to several equiprobable partitions, including the equiprobable partition with the highest estimated power. In all cases but one, the algorithm identified a parttion with higher estimated power than the best equiprobable partition. Applciations of the procedure are discussed.     

Time management as a moderator of relations between stressors and employee strain

The purpose of this study was to examine whether time management behaviours moderated relations between stressors (role conflict, role overload, work-family conflict, and family-work conflict) and strain, as measured by scores on the General Health Questionnaire. It was predicted that use of time management behaviours would be negatively associated with strain. These relations, however, were expected to be mediated by feelings of control over time. It was further predicted that the use of time management behaviours would attenuate stressor-strain relations. Data collected from 525 employed men and women indicated, as predicted, that use of time management behaviours was negatively associated with strain. These relations were partially mediated by feelings of control over time. Moderator tests failed to provide support for time management behaviour as a moderator of stressor-strain relations. Implications of findings are discussed and future directions for time management research are suggested.     

What You Know or Who You Know? Occupation-specific work experience and job matching through social networks

While work experience is generally seen as an indicator of human capital, it may also reflect the accumulation of social capital. This study examines how work experience facilitates informal access to employment—that is, being matched with a new employer through an informal search or informal recruitment through the non-search process (without engaging in a job search). Results from fixed effects regression on panel data from the NLSY show that experience is related to informal entry into new jobs, though in a very specific way. The odds of being informally recruited into a new job improve as work experience in related occupations rises, but this relationship holds only among men. These findings highlight the social benefits of occupation-specific work experience that accrue to men but not to women, suggesting an alternative explanation for the gender disparity in wage returns to experience.     

Organizational perspectives on digital labor market intermediaries

Dramatic changes in organizational forms and employee-employer relationships have coincided with a proliferation of labor market intermediaries. Often digital and internet-based, these new hiring technologies assist organizations in recruiting and screening potential job candidates. We identify three types of digital labor market intermediaries (dLMIs): connectors, curators, and comminglers. We examine the use of dLMIs through the lens of organizational theory, focusing on implications for organizational efficiency, power, and equity. dLMI use is patterned but variable across different organizations and has unintended outcomes that defy efficiency expectations. It poses new constraints for job seekers while allowing organizations and intra-organizational groups to negotiate institutional pressures and power imbalances. Finally, dLMI use appears to reproduce pre-existing inequalities among different types of employees.     

Peer group self-identification in samples of Russian and U.S. adolescents

Most peer group self-identification research has been conducted in the United States. This article examined the generalizability of self-identified group name research among teens in Ufa, a city in the Russian Federation. A cross-sectional, anonymous collection of data on group self-identification, drug use, addiction concern, sensation seeking, and self-rated school performance was collected from 365 10th grade youth in Ufa and 965 10th grade youth in the United States. The results supported the existence of peer group self-identification by youth in both countries and, in general, replicated the findings that youth who self-identify as a High Risk Youth, are relatively likely to use drugs, show greater concern about becoming an addict, report a greater sensation seeking preference, higher levels of depression, and poorer school performance. Implications of these results are discussed.     

Social Work Practice With LGBT Seniors

The Los Angeles Gay & Lesbian Center began providing services to LGBT seniors in 2008. Since then, the Center’s seniors program has grown to over 3,300 clients. It provides a variety of enrichment and support services with the overarching goal of empowering seniors to successfully age in place. This article outlines the service delivery program of the Center’s Seniors Services Department and describes its successes and challenges in meeting the needs of diverse LGBT seniors. It offers future directions for social work practice, policy, and research with LGBT older adults.     

Making better regulation,making regulation better?

Better Regulation is a re-regulatory strategy that has unfolded in Britain (and, of course, beyond, through Europe and the OECD) across the past decade. This article beings by setting out some quantitative indicators of trends in national and local enforcement in three key areas of protective regulation – food hygiene and food safety, workers’ health and safety, and pollution control – from 2003/2004 to 2012/2013. It then goes on, in its main sections, to detail some of the ways Better Regulation under conditions of austerity has worked through at the level of local enforcement via a case study of four Merseyside Local Authorities; in so doing, it draws principally upon qualitative insights from a series of interviews, as well as data gleaned from a further series of Freedom of Information requests. In so doing, it considers how, on the ground, Better Regulation is made. It concludes that Better Regulation appears less about ‘better’ regulation, more about business-friendly regulation with diminishing law enforcement. There is good reason to suggest that regulatory functions will likely be increasingly re-cast as part of growth initiatives.     

Production Teams and Producing Racial Diversity in Workplace Relationships

Production teams have become a dominant form of work organization as labor markets have become increasingly diverse. This transition likely affects coworker networks—possibly undermining entrenched patterns of workplace segregation. Contact theory suggests that teams can foster network diversity when workers cooperate and share values emphasizing mutual respect. Yet variants of conflict theory, including the critical teams literature, contend that the benefits of teamwork may be eroded by associated factors, including peer discipline, work intensification, and job insecurity. This study uses 2006 General Social Survey data to assess whether and how teamwork affects the racial diversity of worker acquaintance networks, contrasting worker‐ and manager‐directed teams. We find a positive relationship between teams and diversity, but only when teams are worker directed. Despite countervailing tendencies highlighted in the literature, teams foster greater cooperation between workers, which in turn promotes cross‐racial friendships. African Americans tend to receive the greatest diversity payoffs from teams. These findings suggest that teamwork can undermine segregation, though only with certain implementations and with variation across groups.
