African-American and white inequality in the nineteenth century American South: a biological comparison

The use of height data to measure living standards is now a well-established method in economic history. By using a new source of nineteenth century Texas state prison records, the present study contrasts the heights of comparable blacks and whites between the Civil War and Reconstruction in the American South. White stature exceeded black stature. Between 1850 and 1870, black stature declined by more than 1 cm but recovered toward the end of the nineteenth century. Postbellum white stature declined by more than 1 1/2 cm over the same period yet never recovered.

Investment model predictions of workplace ostracism on K–12 teachers’ commitment to their schools and the profession of teaching

The purpose of this study was to determine how the ostracism of K-12 teachers influences their commitment to their schools and commitment to the teaching profession. The investment model was used to situate ostracism as a predictor of teacher commitment. Participants were 200 full-time K-12 teachers who completed a survey assessing their experiences with ostracism at work and investment model variables (i.e., investments, quality of alternatives, satisfaction, and commitment). Results confirmed investment model predictions with teachers’ investments, quality of alternatives, and satisfaction predicting their commitment to their schools and profession. Results of mediation models also demonstrated that controlling for teachers’ investments and quality of alternatives, ostracism predicted commitment indirectly through its effect on satisfaction. This study revealed that teacher commitment is explained by investment model predictions, but after controlling for those predictions, is further explained by ostracism from teacher colleagues.     

Child-custody reform and the division of labor in the household

We investigate whether the adoption of joint-custody laws affects the amount of time that married mothers and fathers devote to market and household work. Our findings suggest that custody reform induces a reallocation of time within marriage, with mothers working more in the market and fathers working more in the home. However, fathers lower their labor-force-participation rates in response to custody reform. The patterns in the data are most easily reconciled with models that emphasize shifts in bargaining power to one household member, which is likely the father in the case of joint-custody reform.     

A varying coefficient approach to estimating hedonic housing price functions and their quantiles

The varying coefficient (VC) model introduced by Hastie and Tibshirani [26 T. Hastie and R. Tibshirani, Varying-coefficient models, J. R. Statist. Soc. (Ser. B) 55 (1993), pp. 757–796.[Web of Science ®] , [Google Scholar]] is arguably one of the most remarkable recent developments in nonparametric regression theory. The VC model is an extension of the ordinary regression model where the coefficients are allowed to vary as smooth functions of an effect modifier possibly different from the regressors. The VC model reduces the modelling bias with its unique structure while also avoiding the ‘curse of dimensionality’ problem. While the VC model has been applied widely in a variety of disciplines, its application in economics has been minimal. The central goal of this paper is to apply VC modelling to the estimation of a hedonic house price function using data from Hong Kong, one of the world's most buoyant real estate markets. We demonstrate the advantages of the VC approach over traditional parametric and semi-parametric regressions in the face of a large number of regressors. We further combine VC modelling with quantile regression to examine the heterogeneity of the marginal effects of attributes across the distribution of housing prices.     

A weighted Harrell–Davis distance test with applications to censored data

Consider the standard treatment-control model with a time-to-event endpoint. We propose a novel interpretable test statistic from a quantile function point of view. The large sample consistency of our estimator is proven for fixed bandwidth values theoretically and validated empirically. A Monte Carlo simulation study also shows that given small sample sizes, utilization of a tuning parameter through the application of a smooth quantile function estimator shows an improvement in efficiency in terms of the MSE when compared to direct application of classic Kaplan–Meier survival function estimator. The procedure is finally illustrated via an application to epithelial ovarian cancer data.     

The role of social work field education programmes in the transmission of developmental social work knowledge in Southern and East Africa

This paper reports on the findings of a study on the role of social work field education programmes in the transmission of developmental social work knowledge in Southern and East Africa. It highlights the challenges in locating developmental social work placements and the creativity shown by social work educators in addressing these challenges and improving learning opportunities for social work students. Both academics and students were found to be committed to developmental social work, within a willing practice environment hampered by knowledge, capacity and resource constraints. Social work education was found to be playing a transformative role through the teaching of a developmental social work curriculum and the creation of collaborative developmental social work learning experiences. Social work educators trained and supported agency supervisors in developmental social work, while students served as conduits, modelling developmental social work practice. What has yet to be determined in future research is the students’ perspective of this developmental educational environment.     

The Impact of the Physical Home Environment for Family Carers of People with Dementia: A Qualitative Study

Background: The majority of people with dementia are cared for by their families at home. This study aimed to elicit family carers' perceptions on home environmental aspects and strategies with the view to identify barriers and facilitators when caring for a person with dementia at home.

Design and methods: Thirteen co-resident family carers were engaged in semi-structured in-depth walking interviews. Interviews were recorded, transcribed and analysed using thematic analysis.

Results: Home environments can pose a number of challenges and opportunities. Aspects of the architectural and interior environment (e.g. size, condition, layout and accessibility, familiarity) are perceived as important (Theme 1) as well as a plethora of environmental strategies that encourage independence and comfort at home (Theme 2). Carers' scepticism, timing, costs, property characteristics and mistrust to services are some barriers to implementing environmental strategies (Theme 3).

Conclusions: Carers improvised solutions via trial and error and need further education on strategies to create an enabling and comfortable home environment.     

Being disabled,being a manager: ‘glass partitions’ and conditional identities in the contemporary workplace

This article critically explores the working lives and views of disabled senior staff working in UK organisations. The qualitative research at the core of the article establishes that some disabled people are confounding established notions of disabled people only working in peripheral employment roles by exploring the working lives and perceptions of disabled managers. The findings do, however, point to continued barriers to what disabled staff in senior positions can be seen to do and be organisationally. Here both practical and ontological risk inheres in organisationally induced change, openness about impairment and risky identities. Such ideas, it is argued, present limits to further promotion and workplace inclusion for some disabled managers.
