Race,Residence, and Underemployment: Fifty Years in Comparative Perspective, 1968–2017

High underemployment has been a chronic structural feature of the rural United States for decades. In this paper, we assess whether and how inequalities in underemployment between metropolitan (metro) and nonmetropolitan (nonmetro) areas have changed over the course of the last five decades. Drawing on data from the March Current Population Survey from 1968 to 2017, we analyze inequality in the prevalence of underemployment between metro and nonmetro areas of the United States, paying special attention to differences between white, black, and Hispanic workers. Our results show that the underlying risk of underemployment has increased in both metro and nonmetro areas over the last 50 years. Nonmetro workers have consistently faced greater employment hardship compared to their metro counterparts, and these differences cannot be fully explained by differences in population characteristics. Nonmetro ethnoracial minorities have experienced particularly poor labor market outcomes. The disadvantage of ethnoracial minority status and rural residence is especially pronounced for nonmetro black workers, among whom underemployment has remained persistently high with only modest convergence with other workers. Hispanic workers also face an elevated risk of underemployment, but we observe a unique convergence between metro and nonmetro workers within this population.     

Labour market integration of immigrants: estimating local authority effects

We propose a method for computing indicators of the relative success of local authorities at integrating new immigrants in the labour market, taking account of differences in characteristics of immigrants and local labour markets. The indicator for integration success is based on mean duration from date of residence permit to start of an employment spell. We apply this method to a Danish administrative dataset. Correcting for differences in immigrant characteristics and local labour market conditions has an important impact on the estimated ranking of local authorities. We investigate how robust the ranking is with respect to changes in the specification of criteria for integration success and controls.

Nonparametric bootstrap of sample means of positive-definite matrices with an application to diffusion-tensor-imaging data analysis

This paper presents nonparametric two-sample bootstrap tests for means of random symmetric positive-definite (SPD) matrices according to two different metrics: the Frobenius (or Euclidean) metric, inherited from the embedding of the set of SPD metrics in the Euclidean set of symmetric matrices, and the canonical metric, which is defined without an embedding and suggests an intrinsic analysis. A fast algorithm is used to compute the bootstrap intrinsic means in the case of the latter. The methods are illustrated in a simulation study and applied to a two-group comparison of means of diffusion tensors (DTs) obtained from a single voxel of registered DT images of children in a dyslexia study.     

Climatic conditions and human mortality: spatial and regional variation in the United States

Previous research on climatic conditions and human mortality in the United States has three gaps: largely ignoring social conditions, lack of nationwide focus, and overlooking potential spatial variations. Our goal is to understand whether climatic conditions contribute to mortality after considering social conditions and to investigate whether spatial non-stationarity exists in these factors. Applying geographically weighted regression to a unique nationwide county-level dataset, we found that (1) net of other factors, average July temperatures are positively (detrimentally) associated with mortality, while January temperatures mainly have a curvilinear relationship, (2) the mortality-climatic condition associations are spatially non-stationary, (3) the relationships between social conditions (e.g., social capital) and mortality are stable geographically, and (4) without a spatial approach to understanding the environment-mortality relationship, important spatial variations are overlooked. Our findings suggest that a universal approach to coping with the relationships between rapid climate changes and health may not be appropriate nor effective.     

Staff characteristics and the exclusion of persons with disabilities: evidence from the microfinance industry in Uganda

This study uses survey data from the microfinance industry in Uganda to investigate whether there are differences among industry staff members in beliefs and views regarding persons with disabilities. For several of the questions, various staff sub-groups respond significantly differently. A recurring result is that staff members who have a relative with disabilities often express views that differ from the views of other staff members. Moreover, we find significant differences related to the age of the staff members. For instance, younger staff members are more positive and optimistic regarding the potential to reach more clients with disabilities. The employment position of the individual staff member also appears to be relevant: credit officers are relatively more likely (than other staff types) to indicate that discrimination could be a problem in the microfinance industry. Interestingly, we do not observe any differences in views and beliefs that are related to staff member gender.     

Psychophysiological stress reactions,trapezius muscle activity,and neck and shoulder pain among female cashiers before and after introduction of job rotation

The aim of this study was to evaluate the effects of the introduction of a job rotation model on supermarket cashiers, with respect to psychophysiological stress reactions, muscle activity of the trapezius muscle (which covers the upper back, the neck and the shoulder), and musculoskeletal symptoms in the neck and shoulders. Thirty-one female cashiers were investigated before and after job rotation was introduced. Before the reorganization the participants were only performing cash register work at the checkout counters. After the reorganization they shifted between cash register work and work in different departments in the supermarket. At follow-up the participants, all right-handed, had a significantly lower diastolic blood pressure, and surface electromyography (EMG) showed a significantly decreased muscle activity in the trapezius muscle on the left side. Musculoskeletal symptoms of the neck and shoulders were only partly changed, and there was no change in prevalence of musculoskeletal pain, which was around 70%. From questionnaires, but not from self-ratings during work, it was found that the introduction of job rotation had been experienced as positive in several regards, although the perceptions of stress and hurry were the same at follow-up.     

The moderating role of social support in Karasek's job strain model

The potential stressfulness of an event may depend on how it is appraised by the individual, although up to now there have been no longitudinal studies on the relationship between lay beliefs concerning work stress and perceived strain. This longitudinal study examines how lay theories of work stress at baseline were related to perceived mental strain at follow up. The present paper builds on an earlier study (Furnham, ), using a longitudinal design and a much larger population of the British workforce (N=2270). Lay beliefs were assessed by a scale consisting of 36 items. Factor analysis gave a solution with five factors on perceived causes and four factors of perceived alleviation of work stress. Linear multiple regression analysis revealed significant relations between lay beliefs of work stress at baseline and perceived mental strain as well as job stress 14 months later. The effect sizes were small but of a similar magnitude to those that have been found, for example, in occupational stress-reducing interventions. A problem with the factor analytic approach was the discrepancies between the factor solutions and the relative importance of the perceived causes of work stress. The results from the study suggest that subjective beliefs about work stress merits further analysis as potentially mediating between ‘objective’ working conditions and stress outcomes.     

Migration and the Spatial Concentration of Poverty1

Current Population Survey data are used to estimate the effects of migration of the poor and nonpoor on the spatial concentration of poverty among five categories of counties defined by county poverty rates and, separately, among nonmetropolitan high-poverty areas, central city high-poverty areas, and other areas. During the 1981–1984 period studied, migration patterns of both the poor and nonpoor consistently reinforced pre-existing poverty concentrations. High migration rates of the poor into and out of high poverty counties suggests an equilibrium condition. Implications for theory, research, and policy are discussed.     

Nonmetropolitan Poor Children and Reliance on Public Assistance1

Abstract This research documents trends from 1970 through 1990 in the utilization and ameliorative effects of public assistance among poor children in nonmetropolitan (nonmetro) and metropolitan (metro) America. Results indicate that the families of nonmetro poor children rely more heavily on parental earnings and less so on public assistance when compared to their metro counterparts; that there was a sharp rise over the period in reliance on public assistance, especially among nonmetro children, and a corresponding decline in reliance on earnings; that the ability of public assistance to ameliorate child poverty is modest; and that while the ameliorative effects are always greater in metro than nonmetro areas, this disparity declined over the 1980s owing partially to improvement in nonmetro areas.
