Professors on the Board: Do They Contribute to Society Outside the Classroom?
According to our data, 38.5 % of S&P 1500 firms have at least one professor on their boards. Given the lack of research examining the roles and effects of academic faculty as members of boards of directors (professorâdirectors) on corporate outcomes, this study investigates whether firms with professorâdirectors are more likely to exhibit higher corporate social responsibility (CSR) performance ratings. Results indicate that firms with professorâdirectors do exhibit higher CSR performance ratings than those without. However, the influence of professorâdirectors on firm CSR performance ratings depends on their academic backgroundâthe positive association between the presence of professorâdirectors and firm CSR performance ratings is significant only when their academic background is specialized (e.g., science, engineering, and medicine). Finally, this positive association weakens when professorâdirectors hold an administrative position at their universities
The Use of Sexually Explicit Internet Material and Its Antecedents: A Longitudinal Comparison of Adolescents and Adults
An implicit assumption in research on adolescentsâ use of sexually explicit internet material (SEIM) is that they may feel more attracted to such material than adults, given the âforbiddenâ character of SEIM for minors. However, systematic comparisons between adolescentsâ and adultsâ SEIM use and of its antecedents are missing. We conducted a two-wave panel survey among a nationally representative sample of 1,445 Dutch adolescents and a nationally representative sample of 833 Dutch adults. Adolescentsâ and adultsâ SEIM use was similar. When significant differences in the SEIM use occurred, they indicated that adults used SEIM more often than adolescents. Male adults were the most frequent users of SEIM. No difference in the antecedent structure of SEIM use emerged between adolescents and adults. In both groups, males, sensation seekers, as well as people with a not exclusively heterosexual orientation used SEIM more often. Among adolescents and adults, lower life satisfaction increased SEIM use. Our findings suggest that the frequency of SEIM use and its antecedents are largely the same among adolescents and adults

Inequitable walking conditions among older people: examining the interrelationship of neighbourhood socio-economic status and urban form using a comparative case study
<p>Abstract</p> <p>Background</p> <p>Supportive neighbourhood walking conditions are particularly important for older people as they age and who, as a group, prefer walking as a form of physical activity. Urban form and socio-economic status (SES) can influence neighbourhood walking behaviour. The objectives of this study were: a) to examine how urban form and neighbourhood SES inter-relate to affect the experiences of older people who walk in their neighbourhoods; b) to examine differences among neighbourhood stakeholder key informant perspectives on socio-political processes that shape the walkability of neighbourhood environments.</p> <p>Methods</p> <p>An embedded comparative case study examined differences among four Ottawa neighbourhoods that were purposefully selected to provide contrasts on urban form (inner-urban versus suburban) and SES (higher versus lower). Qualitative data collected from 75 older walkers and 19 neighbourhood key informants, as well as quantitative indicators were compared on the two axes of urban form and SES among the four neighbourhoods.</p> <p>Results and discussion</p> <p>Examining the inter-relationship of neighbourhood SES and urban form characteristics on older people's walking experiences indicated that urban form differences were accentuated positively in higher SES neighbourhoods and negatively in lower SES neighbourhoods. Older people in lower SES neighbourhoods were more affected by traffic hazards and more reliant on public transit compared to their higher SES counterparts. In higher SES neighbourhoods the disadvantages of traffic in the inner-urban neighbourhood and lack of commercial destinations in the suburban neighbourhood were partially offset by other factors including neighbourhood aesthetics. Key informant descriptions of the socio-political process highlighted how lower SES neighbourhoods may face greater challenges in creating walkable places. These differences pertained to the size of neighbourhood associations, relationships with political representatives, accessing information and salient neighbourhood association issues. Findings provide evidence of inequitable walking environments.</p> <p>Conclusion</p> <p>Future research on walking must consider urban form-SES inter-relationships and further examine the equitable distribution of walking conditions as well as the socio-political processes driving these conditions. There is a need for municipal governments to monitor differences in walking conditions among higher and lower SES neighbourhoods, to be receptive to the needs of lower SES neighbourhood and to ensure that policy decisions are taken to address inequitable walking conditions.</p
EFFECTS OF FEEDBACK SIGN ON GROUP GOAL-SETTING, STRATEGIES, AND PERFORMANCE
Previous research on the effects of feedback sign on goal setting and performance at the individual level suggests that individuals who receive negative feedback perform at higher levels and set higher goals than individuals who receive positive feedback. However, little research has been conducted to examine the effects of feedback sign on group goals and performance. The purpose of the present study was to examine the effects of feedback sign on group goal setting, strategy development, and task performance. Fifty-nine, three-person groups participated in a group word recognition task. Groups were exposed to either positive or negative feedback after completing the task. They were then asked to write down their strategies as a group and to perform the task a second time. The results suggested that, although groups that received negative feedback were less satisfied, these groups set higher goals, developed more strategies, and performed at higher levels than groups that received positive feedback. Exploratory path analysis of the data also suggested that both feedback sign and performance at Time 1 had an indirect effect on performance through group goals
