Gambling participation in the U.S.--results from a national survey

Demographic patterns of gambling participation in the U.S. were examined. A national telephone survey was conducted with 2,630 representative U.S. residents aged 18 or older. The sample as weighted for analysis was 48% male, 12% black, and 11% Hispanic. Respondents were questioned on 15 types of gambling: how often they played and how much they won or lost. Eighty-two percent gambled in the past year. Lottery was the most commonly played game, while casino gambling accounted for the largest extent of gambling involvement. Men and women were equally likely to gamble in the past year, but men gambled more frequently and had larger wins and losses, particularly on sports betting and games of skill. Blacks were less likely to have gambled in the past year, but blacks who gambled did so more heavily than other racial groups. Blacks and Hispanics were more likely than average to be pathological gamblers. The rate of past year gambling declined with age, but extent of gambling involvement among gamblers did not vary with age. Rates of participation in most forms of gambling increased with socioeconomic status, but higher socioeconomic status gamblers had lower rates of pathological gambling, and lower extent of gambling involvement, particularly for lottery. New Englanders gambled more heavily than other Americans. Comparison with past studies showed an increase in overall gambling participation in the U.S., and large increases in rates of participation in lottery and casino gambling.     

The effect of unions on labor markets and economic growth: An analysis of state data

Despite voluminous research on unions, there still is no consensus on how unions affect a state's economy. Using a panel of 48 U.S. states for the 1978–1994 period, we estimate a series of simultaneous equations to analyze how unions affect various economic barometers. This provides measures for the partial correlations between unions and performance. The model is then re-estimated using regional dummies to capture fixed effects and to highlight regional differences in the slope of the Phillips curve. We find that unions adversely affect unemployment rates and the growth rates of gross state product (GSP), productivity, and population, while increasing the rate of wage inflation. The impact on the employment growth rate is negative but not significant. A test for fixed effects reveals regional differences in GSP growth. Regional differences in popu-lation growth are not significant. Also, the slope of the Phillips curve is significantly dif-ferent across regions.     

Religiosity and preferences for life-prolonging medical treatments in African-American and white elders: a mediation study

Research on end-of-life treatment preferences has documented robust racial differences, with African-Americans preferring more life-prolonging treatment than Whites. Although little research has attempted to explain these racial differences systematically, speculation has centered on religiosity. We examined a dimension of religiosity frequently invoked in end-of-life research-guidance by God's will-as a potential mediator of racial differences in such treatment preferences. Three hundred African-American and White men and women aged 60 or older participated in a 35-minute telephone interview that elicited preferences for four common life-prolonging treatments in each of nine health scenarios. The questionnaire included the five-item God's will (GW) scale, a health conditions checklist, a depression measure, and sociodemographic questions. GW mediated racial differences at least partially for most treatments and in most health scenarios. Implications are discussed for understanding end-of-life treatment preferences and why races tend to differ.     

Patterns of parental bereavement following the loss of a child and related factors

This study investigated the patterns of parental bereavement in 20 parents who have lost a child to cancer, congenital heart disease, meningitis, or drowning in the last 19 months, using semi-structured interviews and standardized questionnaires of depression and grief. Qualitative content analysis of interviews identified three bereavement patterns: The majority of parents (65%) presented uncomplicated, Integrated Grief five mothers were Consumed by Grief and one mother and one father expressed Minimal Grief. Quotes from parents exemplified these patterns. Parental gender, symptoms of depression, and pre-death relationship between parents and their deceased child differentially related to these patterns. Having surviving children, social support, and being active appeared to help to integrate grief into daily life. These findings illustrate differential patterns of parental bereavement and related factors, information that has important implications for identifying at-risk parents for complicated bereavement.     

A systematic review of the relationship between urban agriculture and biodiversity

Urban agriculture is a unique form of agriculture that can provide fresh, local produce for urban residents, and may benefit biodiversity by decreasing the need to expand agriculture into natural areas as well as enhancing biodiversity in urban areas. However, although urban agriculture is also often cited as promoting biodiversity in urban areas, the extent of empirical evidence for such claims has not been studied. Here we systematically review the relationship between urban agriculture and biodiversity in the scientific literature. We strictly define urban agriculture as areas in cities that grow produce specifically for human consumption. We examined 148 papers from 2000 to 2017, of which only 24 studies fit our definition of urban agriculture, and of those, only 18 both involved urban agriculture and measured biodiversity. Of the studies that did measure biodiversity, some showed increases in diversity compared to urban vacant lots, but other showed no difference. Moreover, these studies were mostly focused on plants and invertebrates and were conducted almost exclusively in North America. In order to use the generalization that urban agriculture will have a positive influence on urban biodiversity, more studies will need to be conducted across a wider geographic range worldwide (particularly in developing countries in the tropics) and on a greater diversity of species and taxa (e.g., herpetiles, birds and small mammals). Such studies will likely increase in conservation importance as urban expansion and agricultural demands increase globally.     

Teil-autonome Arbeitsteams oder tayloristische Produktionslinie? Welche Erkenntnisgewinne bieten simulationsbasierte Work Design Trainings

Digitalisation, flexible job markets, new technologies and innovative forms of collaboration constitute increasing challenges for employers and the design of modern work. But how can we deal with these challenges and what do we know about the effect of good versus bad work design? Based on the job demands-resources model (JRM), we present a simulation-based training during which participants experience the effects of different work characteristics. We focus on the moderating effects of job control and job demands: The JRM assumes that job demands and job control interactively affect employee exhaustion and work engagement: Jobs with high control can buffer the strain-enhancing effect of job demands (buffer hypothesis) and increase work engagement (active learning hypothesis). We test these hypotheses in a workplace simulation during which participants have to produce ice-cream. Our results support the buffer hypothesis but not the active learning hypothesis. We discuss the added value of work design simulations for organisations, practitioners, and HR professionals.     

Body Image Disturbances and Predictors of Body Dissatisfaction Among Hispanic and White Preadolescents

This study assessed ethnic and gender differences in ideal body size, body dissatisfaction (BD), and the relationship between BD and various predictors (e.g., body composition indicators and cardiorespiratory fitness). The sample consisted of 190 White and Hispanic preadolescents aged 10–13 years. Demographic, percent body fat (%BF), body mass index (BMI), body image variables, and cardiorespiratory fitness (CRF) were examined. A significant Gender × Ethnicity interaction was found for ideal body size (p < .05), with Hispanic girls preferring the thinnest figures and Hispanic boys the largest figures, compared to their counterparts. No significant gender or ethnic differences in BD were observed. After controlling for demographic and cultural variables, increased %BF and BMI scores predicted greater BD, whereas CRF did not.
