Shedding light on economic opportunity: skin tone and job quality during the Great Recession

A significant body of literature suggests that skin-tone segmentation is a salient characteristic of inter-group economic inequality in the United States. Yet, empirical investigations of this social phenomenon and its impact on labour-market outcomes for worker’s in the United States remains limited or focused on the impact of skin tone on wages. This article examines whether or not phenotypic variability in skin tone among workers influenced levels of job quality experienced during the recessionary era (2007–2012). Data from the Puerto Ricans and the Impact of the Great Recession Survey were used to estimate a Poisson Regression with Endogenous Treatment Effects to consider the impact that variations in skin tone have on levels of job quality experienced by workers. Findings suggest evidence of skin-tone labour-market segmentation, as workers with darker skin shades experienced lower levels of job quality than those workers with lighter skin tones within and across larger racial and ethnic groups. The results also suggest important regional variations in the experience of skin-tone labour-market segmentation in the United States. The article concludes by reflecting on the implications of the findings for racial economic inequalities and patterns of social stratification in the contemporary United States.     

How to take a penalty

When Rob Eastaway told friends he was embarking on a project to write a book about the maths of sport, they didn't hear the word "maths"-they heard "statistics". That, after all, is the most obvious interpretation. But, as he discovered, mechanics, geometry and even some mathematical history all play their part.     

From Cowboys to Diplomats: Challenges for Social Entrepreneurship in The Netherlands

Social entrepreneurship—a new business model that combines a social goal with a business mentality—is in a transitional phase, from a rough cowboy market to a more established market niche. This process results in two interconnected dilemmas for the social entrepreneur. First, how it can capture market share despite its role as an antagonist to current market values. Second, how it can prevent the loss of its own core values in the course of greater interaction with the incumbent regimes. Using a tool known from innovation sciences to analyse radical innovations, namely strategic niche management, and both survey data and interviews from actors in the Netherlands, this article shows that social entrepreneurs have an attitude that is still more in line with the cowboy market than with the new diplomatic role they are expected to take on. Subsequently, it provides recommendations on how to achieve this new attitude.     

Development and piloting of a mother and child intervention to promote resilience in young children of HIV-infected mothers in South Africa

This paper describes the process of developing a parallel intervention for HIV-positive mothers and their young children (6-10 years) with a view to strengthening the relationship between them. Strong mother-child relationships can contribute to enhanced psychological resilience in children. The intervention was developed through action research, involving a situation analysis based on focus group discussions; intervention planning, piloting the intervention and a formative evaluation of the intervention. Participants supplied feedback regarding the value of the intervention in mother-child relationships. The findings obtained from the formative evaluation were used to refine the intervention. Two parallel programmes for mothers and children (15 sessions each) were followed by 10 joint sessions. The intervention for mothers focused on maternal mental health and the strengthening of their capacity to protect and care for their young children. The intervention for children addressed the development of their self-esteem, interpersonal relationships and survival skills. The formative evaluation provided evidence of good participation, support and group cohesion. Qualitative feedback indicated that the activities stimulated mother-child interaction. A similar intervention can easily be applied elsewhere using the detailed manual. The insights gained and lessons learnt related to mother and child interaction within an HIV-context that emerged from this research, can be valuable in other settings, both in Sub-Saharan Africa and elsewhere.     

The Forgotten (Practical) Side of School Safety: What Do Clery Reports Say about CPTED and Crime on College Campuses?

ABSTRACT

Following incidents of school violence, common discourse often neglects the role of practical approaches, such as CPTED, to safeguard campuses. This study utilized a content analysis of U.S. Clery Act Safety Reports from a national, randomly drawn stratified sample of n=100 American universities to determine the extent CPTED techniques were implemented. Findings suggested that 1) CPTED use is limited; 2) two CPTED techniques, access control and activity support, were most common; 3) institutions with higher crime rates tended to have implemented more CPTED measures; and 4) CPTED use appears to be related to less severe campus crimes. Implications are discussed.     

A two-phase algorithm for bin stretching with stretching factor 1.5

Online Bin Stretching is a semi-online variant of bin packing in which the algorithm has to use the same number of bins as an optimal packing, but is allowed to slightly overpack the bins. The goal is to minimize the amount of overpacking, i.e., the maximum size packed into any bin.We give an algorithm for Online Bin Stretching with a stretching factor of 1.5 for any number of bins. We build on previous algorithms and use a two-phase approach. However, our analysis is technically more complicated and uses amortization over the bins with the help of two weight functions.
