Scholarly Productivity of Social Work Faculty at Historically Black Colleges and Universities: Are h-Index Scores a Suitable Measure?

Faculty scholarship at historically Black colleges and universities (HBCU) has in the past served as a blueprint for the Black masses. Even today, HBCU faculty scholarship continues to be an informative source to communicate accurate information regarding marginalized groups. This study examines h-index scores of 65 faculty members at five doctorate-granting schools of social work. The majority of calculated h-index scores were considered to be low in terms of productivity. We make the argument that these scores are not a good measure of productivity because of the problematic nature of their use to evaluate HBCU faculty. Implications for future research, practice, and teaching are presented.     

Outlier detection in contingency tables based on minimal patterns

A new technique for the detection of outliers in contingency tables is introduced, where outliers are unusual cell counts with respect to classical loglinear Poisson models. Subsets of cell counts called minimal patterns are defined, corresponding to non-singular design matrices and leading to potentially uncontaminated maximum-likelihood estimates of the model parameters and thereby the expected cell counts. A criterion to easily produce minimal patterns in the two-way case under independence is derived, based on the analysis of the positions of the chosen cells. A simulation study and a couple of real-data examples are presented to illustrate the performance of the newly developed outlier identification algorithm, and to compare it with other existing methods.     

Still the Favorite? Parents' Differential Treatment of Siblings Entering Young Adulthood

This study examined within‐family stability in parents' differential treatment of siblings from adolescence to young adulthood and the effect of differential treatment in young adulthood on grown siblings' relationship quality. The author used longitudinal data on parent–child and sibling relations from the sibling sample of the National Longitudinal Study of Adolescent Health (N = 1,470 sibling dyads). Within‐dyad fixed effects regression models revealed that the adolescent sibling who was closer to parents went on to be the young adult sibling who was closer to and received more material support from parents. Results from an actor–partner interdependence model revealed that differential parental financial assistance of young adult siblings predicted worse sibling relationship quality. These findings demonstrate the lasting importance of affect between parents and offspring earlier in the family life course and the relevance of within‐family inequalities for understanding family relations.     

What are the Differences between Happiness and Self-Esteem

The present study investigated theoretically and empirically derived similarities and differences between the constructs of enduring happiness and self-esteem. Participants (N = 621), retired employees ages 51–95, completed standardized measures of affect, personality, psychosocial characteristics, physical health, and demographics. The relations between each of the two target variables (happiness and self-esteem) and the full set of remaining variables were assessed through a series of successive statistical analyses: (1) simple Pearson’s correlations, (2) partial correlations, and (3) hierarchical regression analyses. The results revealed that happiness and self-esteem, while highly correlated (r = 0.58), presented unique patterns of relations with the other measured variables. The best predictors of happiness were the following: mood and temperamental traits (i.e., extraversion and neuroticism), social relationships (lack of loneliness and satisfaction with friendships), purpose in life, and global life satisfaction. By contrast, self-esteem was best predicted by dispositions related to agency and motivation (i.e., optimism and lack of hopelessness). Implications for the understanding of happiness and self-esteem are discussed.     

Management mitigates the impact of urbanization on meadow vegetation

Urban regions often contain remnants of ecologically valuable habitats. Whilst meadow habitats have been recognized as ecologically important and much studied, little attention has been given to meadow assemblages of urban locations. We studied the effects of meadow type, urbanization level, and management on vascular plant species richness, field layer diversity and soil chemistry in 18 grassland sites in the Helsinki Metropolitan Area (60°E, 25°N), on the southern coast of Finland during the summer of 2007. We recorded a total of 252 species, though the average number of species per m² was only 12.6. The negative effects of urbanization on forbs seemed to result in particular from increased soil nitrate (NO₃^- -N) concentration. The highest NO₃^- -N and Fe concentrations and ratios of total inorganic nitrogen (N_tot) to phosphorus (P) and potassium (K), were recorded from the soils of urban rocky meadows. Management by mowing decreased soil NO₃^- -N and Fe concentrations, ratios of N_tot:P and N_tot:K, and increased species richness and diversity. Elevated NO_x deposition is considered as a major driver of urbanization effects on vegetation, though changes in soil pH and metal concentrations, such as zinc (Zn), may also negatively affect the frequency of both forbs and grasses. This study shows that regular management by mowing and removal of hay mitigates these effects. We also recommend increasing the provision of dry meadows and maintaining more areas of supplementary semi-natural grassland habitats in urban green space as concrete measures for the conservation of dry meadow assemblages and urban biodiversity.     

Calling social capital: An analysis of the determinants of success on the TV quiz show “Who Wants to Be a Millionaire?”

This paper analyzes the determinants of successful participation of candidates on the well known television quiz show “Who Wants to Be a Millionaire?”. Our study includes a survey of 660 contestants who participated in the German version of the show between 1999 and 2007. We are particularly interested in two hypotheses. The first hypothesis refers to the assumed advantage of social capital. Contestants on the show have the option of calling a friend (the phone-a-friend lifeline) whom they select from their personal networks. The person chosen to be the phone-a-friend lifeline should be especially helpful if the contestant has a large network of able contacts from which to choose. Second, according to human capital theory the participants’ education should increase the chances of success and should lead on average to higher payoffs. Since contestants on the show can answer questions correctly mainly on the basis of their knowledge and since other characteristics of the candidates are irrelevant, estimates of the human capital effect are not affected by other possible causes suggested by signaling theory. Thus, our analysis is an assessment of the effects of social capital and human capital on the show.     

Heterogeneity in life-duration preferences: Are risky recreationists really more risk loving?

We conduct multiple price list experiments that elicit life duration risk preferences from amateur auto racers, technical rock climbers, SCUBA divers, and a student control group. We posit a preference function that allows for risk aversion and probability weighting. We are particularly interested in whether the behavior of risk takers, such as risky recreationists or smokers, is best explained by a risk-tolerant utility function or if immunity to possibility bias arising from overweighting of low probabilities is a more important motivator of the choice to engage in risky activities. We find that amateur auto racers are more rational than either students or other risky recreationists because they are less likely to overemphasize low-probability events. Women, older subjects, and rock climbers are more susceptible to possibility bias than others, making them likely to overinvest in disease treatments that have a low probability of success.     

Instantanés de la situation des jeunes générations sur le marché du travail aux Pays-Bas

La relation de travail Ṣtypiqueṣ perd du terrain aujourd'hui. Les jeunes sont particulièrement touchés par cette évolution. Dans ce contexte, les auteures examinent dans le détail le parcours d'insertion des générations arrivées sur le marché du travail des Pays-Bas entre 1985 et 2014, en procédant sur le modèle de l'analyse séquentielle des parcours de vie. Avec deux indicateurs spécifiques (niveau d'entropie et de turbulence), elles montrent que la trajectoire des cohortes qui s'insèrent après 2000, notamment en 2008, est effectivement plus accidentée, et ce malgré la politique de flexisécurité à l'honneur dans le pays. Les transitions vers l'emploi stable sont l'exception plutôt que la règle.
