Relations of Temperament to Maladjustment and Ego Resiliency in At‐risk Children

The relations of control/regulation‐related temperamentally based dispositions (effortful control (EC), impulsivity, and approach/avoidance) to externalizing problems and personality ego resiliency were examined in a sample of 467 children (M age = 7.46 years), some of whom were children of alcoholics (COAs). In addition, we examined if the relations of temperamental regulation/control to maladjustment/ego resiliency were moderated by COA status or sex of the child. In general, regulated, controlled temperament was negatively related to externalizing problems and EC was positively related to ego resiliency. Relations between a problematic temperament and externalizing problems were stronger and sometimes only found for COAs, especially male COAs. Ego resiliency was positively related to high father‐reported approach for boys who were not sons of alcoholics. In addition, COA status was related to high impulsivity, approach behavior, and externalizing problems and low EC.     

Comparison of two methods of measuring physical activity in South African older adults

The aim of this study was to assess the validity and reliability of the Yale Physical Activity Survey (YPAS) and the short version of the International Physical Activity Questionnaire (IPAQ) in older South African adults. The YPAS includes measures of weekly energy expenditure (EE) for housework, yard work, caregiving, exercise, and recreation. The IPAQ measures total time and EE during vigorous and moderate activity, walking, and sitting. The instruments were administered twice for test-retest reliability (men, n = 52, 68 +/- 5.4 years, and women, n = 70, 66 +/- 5.8 years). Data for criterion validity were obtained from accelerometers. YPAS reliability ranged from r = .44 to.80 for men and r = .59 to .99 for women (p < .0001). IPAQ reliability was lower for men (r = .29 to .76) than for women (r = .46 to .77). Criterion validity of the YPAS was .31 to .54 for men and .26 to .29 for women. The YPAS and short IPAQ had comparable results for reliability and criterion validity.     

Donative labor effect of the nonprofit pay: A multilevel explanation

Studies on the nonprofit pay differential find that nonprofit workers in the child day care industry earn more than comparable for‐profit workers, whereas nonprofit lawyers earn less than lawyers in for‐profit firms. Are nonprofit day care center workers less altruistic than for‐profit day care workers or nonprofit lawyers? The answer is yet to come. The study aims to test the donative labor hypothesis, which is derived from altruistic motivation. To estimate the donative labor effects on the individual level, I apply cross‐classified multilevel modeling to disentangle the confounding effects on the industry level and occupation level. Data are pooled from Census 2000 and American Community Survey 2005–2016 to provide individual, industry, and occupation information. Industries are cleaned based on the Statistics of Income data from the National Center for Charitable Statistics. My analysis finds that nonprofit workers earn 4.3% less than comparable for‐profit workers net of industry and occupation effects. The study contributes to elucidating the explanatory levels of different theories. The random‐effects modeling has established an exhaustive inventory of nonprofit pay differential across industry and occupation levels.
