Drug testing laws and employment injuries

Employer use of employee drugscreening procedures is widespread in the U.S. A state-by-state analysis of statutory law applicable to the drug testing issue is combined with state and industry data to isolate how drug testing laws affect workplace injury rates. Based on our data, injury rates are not statistically related to the state’s legal environment.     

Identification Properties of Recent Production Function Estimators

This paper examines some of the recent literature on the estimation of production functions. We focus on techniques suggested in two recent papers, Olley and Pakes (1996) and Levinsohn and Petrin (2003). While there are some solid and intuitive identification ideas in these papers, we argue that the techniques can suffer from functional dependence problems. We suggest an alternative approach that is based on the ideas in these papers, but does not suffer from the functional dependence problems and produces consistent estimates under alternative data generating processes for which the original procedures do not.     

Fast and approximate exhaustive variable selection for generalised linear models with APES

We present APproximated Exhaustive Search (APES), which enables fast and approximated exhaustive variable selection in Generalised Linear Models (GLMs). While exhaustive variable selection remains as the gold standard in many model selection contexts, traditional exhaustive variable selection suffers from computational feasibility issues. More precisely, there is often a high cost associated with computing maximum likelihood estimates (MLE) for all subsets of GLMs. Efficient algorithms for exhaustive searches exist for linear models, most notably the leaps‐and‐bound algorithm and, more recently, the mixed integer optimisation (MIO) algorithm. The APES method learns from observational weights in a generalised linear regression super‐model and reformulates the GLM problem as a linear regression problem. In this way, APES can approximate a true exhaustive search in the original GLM space. Where exhaustive variable selection is not computationally feasible, we propose a best‐subset search, which also closely approximates a true exhaustive search. APES is made available in both as a standalone R package as well as part of the already existing mplot package.     

The practice of ‘Othering’ in reaffirming white working-class boys’ conceptions of normative identities

This paper considers how the practice of ‘Othering’ is used by white working-class boys in Boremund, South London to mark identity boundaries and reaffirm their habitus. Through unearthing themes of difference within the young men’s accounts, the work identifies various ways of ‘doing masculinity’ in two social groups, ‘Boremund Boys’ and ‘emos’, who contrasted greatly in style but who were of the same race, class, and ethnicity. Focusing on the identity negotiations of a small cohort, aged 14–16, the data indicate how a normative white male identity specific to this locale is policed and how ‘Othering’ is employed as a strategy. Using Bourdieu’s tools alongside the hermeneutic of heteronormativity, the research explores how emos, through inverting a traditional working-class masculinity, brought the habitus of Boremund Boys into disjuncture. Within the field of masculinity, the habitus of Boremund Boys, through a process of reorientation, reconciles competing and contrasting conceptions of what it is to be a white working-class male in South London.     

Blurring the lines for learning: the role of out-of-school programs as complements to formal learning

As debates continue over the effectiveness of after-school programs, we need to create stronger links between schools and out-of-school activities. Where do such connections begin? How can we integrate skill-building and academic competence into the out-of-school-time context?     

The Accuracy of Respondent-Coded Occupation

This study reports results from a methodological experimentconducted in a national survey to test the accuracy of respondent-codedoccupation. For most uses, we conclude that such measures aresufficiently precise. There are, however, some systematic sourcesof error which the investigator should be aware of.     

Maternal Functioning, Time, and Money: The World of Work and Welfare

Numerous studies have assessed families' employment and financial stability following welfare reform. Yet little research has addressed whether welfare and work transitions are linked with other changes in family functioning. Using a representative sample of approximately 2,000 low-income urban families from the Three-City Study, analyses assessed whether mothers' welfare and employment experiences over a two-year period following welfare reform were related to changes in family well-being. Lagged regression models controlling for family characteristics and earlier levels of functioning found that moving into employment and stable employment (of 30 hours or more per week) were linked to substantial increases in income and improvements in mothers' psychological well-being. Movements into employment also were associated with declines in financial strain and food insecurity. Sustained or initiated welfare receipt was related to relative declines in income, physical health, and psychological well-being, but also to improved access to medical care. In contrast, mothers' welfare and work experiences showed very limited relations to changes in the quality of parenting or of children's home environments. These patterns were similar for families with young children and those with adolescent children. Results suggest that parenting behaviors are more resistant to change than are maternal emotional and economic functioning.     

Dilemmatic Constructions of Career in the Career Counseling Interview

Thirty career counseling interviews were recorded and inductively analyzed using a discourse analytic method. Findings indicate that clients in this setting present various dilemmatic themes of career in their talk. Three types of dilemmas were pervasive: uncertainty versus certainty, interests versus practical, and focus versus options. The findings suggest that career theorists and practitioners might find it useful to address the dilemmatic processes evident in “career talk.”
