Measuring Socio-Demographic Differences in Volunteers with a Value-Based Index: Illustration in a Mega Event

The phenomenon of volunteering can be analysed as a consumer experience through the concept of value as a trade-off between benefits and costs. In event volunteering, both the expected value (pre-experienced) and the perceived value (post-experienced) of volunteering can be assessed. With this purpose, an online quantitative survey is conducted with a sample of 711 volunteers in a religious mega event, with questions related to five dimensions of their experience: efficiency, social value, play, spirituality and time spent. These five scales, properly tested are used for building a multidimensional index of both the expected and perceived value of the volunteer experience. ANOVAs test show significant differences on the index in both moments upon the socio-demographic profiles: negative expectations/experience balance by age, contrasted results by sex, and more experienced volunteers being more critical with the value experienced. Implications for event managers are proposed, in line with the motivation of volunteers.     

Birds of a Feather,or Friend of a Friend? Using Exponential Random Graph Models to Investigate Adolescent Social Networks

In this article, we use newly developed statistical methods to examine the generative processes that give rise to widespread patterns in friendship networks. The methods incorporate both traditional demographic measures on individuals (age, sex, and race) and network measures for structural processes operating on individual, dyadic, and triadic levels. We apply the methods to adolescent friendship networks in 59 U.S. schools from the National Longitudinal Survey of Adolescent Health (Add Health). We model friendship formation as a selection process constrained by individuals’ sociality (propensity to make friends), selective mixing in dyads (friendships within race, grade, or sex categories are differentially likely relative to cross-category friendships), and closure in triads (a friend’s friends are more likely to become friends), given local population composition. Blacks are generally the most cohesive racial category, although when whites are in the minority, they display stronger selective mixing than do blacks when blacks are in the minority. Hispanics exhibit disassortative selective mixing under certain circumstances; in other cases, they exhibit assortative mixing but lack the higher-order cohesion common in other groups. Grade levels are always highly cohesive, while females form triangles more than males. We conclude with a discussion of how network analysis may contribute to our understanding of sociodemographic structure and the processes that create it.     

Does parenting correspond with children's defending behavior? Examining linkages in the context of peer social preference

Bullying intervention research points to the important role of children standing up for victims (defending behavior). This study provides an initial look at how certain parenting practices may be generally related to the socialization of defending behavior among children. Defenders typically enjoy significant social status, allowing them the social capital to intervene. With this in mind, we also assess how parenting and children's social preference scores might uniquely or interactively predict defending behavior. This cross‐sectional study employs a sample of 219 (101 boys) fourth‐grade children living in the Western United States. Both mothers and fathers self‐reported their authoritative, authoritarian, and psychologically controlling parenting practices. A peer sociometric assessment provided each child's social preference score. Peer nominations provided each child's reputation for defending behaviors. Multiple regression results showed that a few of the parenting dimensions significantly predicted girls’ defending behavior above and beyond peer social preference. In contrast, the defending behavior scores of boys were unrelated to parenting. Finally, we used interaction analyses to probe whether the association between defending and parenting meaningfully varies according to children's levels of social preference. We did not find evidence to support this. We discuss the ramifications of these findings for future research.     

Corporate Reputation: Do Board Characteristics Matter?

Our study draws on institutional and signalling theories to postulate relationships between board characteristics and corporate reputation. Based on a sample of 324 firms featured in Fortune's list of most admired corporations in the USA, our findings indicate that board characteristics significantly influence the assessment of firm reputation by the business community. Specifically, we found that firms with a greater proportion of outside directors and those with larger boards exhibited better reputation than those with smaller boards and a higher proportion of insiders. In addition, we observed an inverted‐U relationship between the average tenure of outside directors and corporate reputation. However, contrary to expectations, our findings indicate a negative association between independent leadership structure (i.e. absence of duality) and corporate reputation.     

Intergenerational Transfers to Adult Children in Europe: Do Social Policies Matter?

Understanding the role of social policies in intergenerational transfers from old to young people is especially important in times of population aging. This paper focuses on the influences of social expenditures and social services on financial support and on practical help from older parents to their adult children based on the first two waves from the Survey of Health, Ageing and Retirement in Europe (SHARE, N = 60,250 dyads from 13 European countries). Multilevel models showed that social policy plays an important role for intergenerational transfer patterns: The more public assistance was provided to citizens, the more likely parents supported their adult children financially and practically, but this support was less intense in terms of money and time given. Thus, the analyses support the specialization hypothesis that posits a division of labor between family and state for downward intergenerational transfers.

Ausbildung von Schlüsselqualifikationen im Fachbereich Wirtschaft

An important goal of the Bologna Process is the improvement of employability. Universities are required to develop courses for the acquisition of key competences. The Department of Business and Management at Bochum University of Applied Sciences has developed an extensive training program for that offers an introduction to the methods “mentoring”, “coaching” and “group dynamics” to the participants. The acquired skills can be put into practise immediately by mentoring new students.
