Innovationsverhalten in Familienunternehmen

Family businesses are publicly believed to be highly innovative and to be the “Hidden Champions” of the German industry. In recent times scholars have begun to examine this thesis and have come to starkly opposing results. On the one hand family businesses are attested to have a special ?entrepreneurial “spirit” which makes them highly innovative. On the other hand the lack of separation of ownership and control and insufficient diversification of family-investors are said to lead to less innovation activity. In this study we investigate the innovation activity of 384 German manufacturing firms differing in legal structure, size, age, industry, and—most importantly—in the degree of family ownership, family management and family control. The results of our analysis reveals differentiated results. Fundamentally, family ownership and family management are detrimental to firm innovation, at the same time family control has a positive impact on innovation activities. Our Results point to the fact that owner-managed businesses tend to innovate less due to risk aversion while a focus on controlling instead of managing a corporation by the owning family lead to an increase in innovations.     

Determinants of Rural Physicians' Life and Job Satisfaction

Objective: To identify and quantify factors that contribute to rural physicians' satisfaction with their jobs and life as a whole.Design: Cross-sectional, mailed survey. Study population: Family physicians practicing in rural communities eligible for British Columbia's Northern and Isolation Allowance. Main measures: Demographics, Domain satisfaction, Maslach Burnout Inventory, Beck Depression Inventory, and Life Satisfaction.Results: Stepwise multiple regressions reveal the greatest predicators of rural physician overall life satisfaction are satisfaction with jobs, personal relationships, health, finances, and absence of depression. These predictors account for 70% of the variation in rural physician overall life satisfaction. The greatest predictors of rural physician satisfaction with jobs and satisfaction with current place of residence/practice, on-call shifts, personal accomplishments, and absence of emotional exhaustion. The predictors account for 44% of the variation in rural physician job satisfaction.     

Regret, disappointment and the endowment effect

The endowment effect is the finding that minimum selling prices for a particular good exceed maximum buying prices. We build on and extend previous research showing that emotions influence the endowment effect, and reveal that the two negatively valenced decision-related emotions, regret and disappointment, have distinct effects on the valuation of an object. We found that an induction of regret eliminates the classic endowment effect, whereas an induction of disappointment reverses it. The findings demonstrate the necessity of a specific emotion approach to understand the effects on decision making.     

Sexual violence victimization among female secondary school students in eastern Ethiopia

Behavioral, lifestyle, and relationship factors have all been identified as risk factors that increase a woman's vulnerability to sexual violence victimization. However, it remains unclear which risk factors most strongly increase young women's vulnerability to sexual violence victimization because most studies only examine a few factors simultaneously. Using a cross-sectional sample of 764 female secondary school students from eastern Ethiopia, multivariate analyses revealed that high-rejection sensitivity, having multiple sexual partners, the frequent watching of pornography, and use of alcohol or other soft drugs (Khat or shisha) are factors associated with higher levels of sexual violence victimization. The overall rates of victimization is high in this group, with 68% of the young women studied having experienced at least one instance of sexual violence victimization. Based on type of sexual perpetration, 52% of the young women were victimized by at least one instance of sexual offence, 56% by sexual assault, 25% by sexual coercion, and 15% by sexual aggression. Qualitative data gathered from interviews of extracurricular club members and school officials and focus group discussion with students were used to further augment and illustrate results from the quantitative data. Several suggestions for intervention are presented in light of these results.     

Gerechtigkeit und Arbeitskontext – Zur Bedeutung situativer Merkmale für die Gerechtigkeitswahrnehmung von Führungskr?ften

Leaders who are perceived to act with fairness can evoke desired employee behaviour in unique ways. Until now, little attention has been paid to the influence of situational factors on judging leader??s fairness in the work context. Based on the event paradigm, this study explores the formation of employee??s perception of leader??s justice in the context of work distribution through a variety of situational factors. Using a factorial survey we show that not only well-known factors such as respectful and reasonable behaviour affect the perception of leader??s fairness but also situational factors such as speech situation, trust between leader and follower, and the quality of the task.     

Benefits of Model-based Drug Development: A Rigorous,Planned Case Study

Model-based drug development (MBDD) is useful to make better quantitative decisions within drug development. However, rigorous evaluation of the benefits has been scarce in the literature. In this study, we take a completed development program, retrospectively repeat it in a virtual setting using MBDD methodologies, and compare it to the traditional drug development process. The conclusion is that the use of MBDD could have facilitated more efficient use of resources.     

The abscissa of convergence of the laplace-stieltjes transform of a ph-distribution

If a probability distribution of phase type has an irreducible representation (α,T), the abscissa of convergence of its Laplace-Stieltjes transform is shown to be the eigenvalue of maximum real part of the matrix T.     

Neighborhood does matter!

The discontinuation of social housing projects has lead to increasing tendencies of social segregation in German cities over the past decades. American and recently also European research has frequently shown that the increasing social segregation of neighbourhoods produces contextual effects on the educational success of children and youths living in the respective neighbourhoods. This contribution draws on data from the Berlin ELEMENT-study to investigate whether socio-cultural neighbourhood characteristics have an effect on the competence development of elementary school children in the time span between 4th and 6th grade. Results indicate that—apart from individual composition effects—living in a socially deprived neighbourhood does not have a negative effect on student’s competence development. On the other hand living in a privileged neighbourhood does in fact have a positive effect on student’s competence development—independently of composition effects. Therefore, educational inequalities are indeed intensified by neighbourhood effects, but not in the way that deprived neighbourhoods have a negative effect on the competence development of students living in them but rather in the way that living in a neighbourhood characterized by a favourable social structure positively affects student’s competence development.     

Running on age in a 15-km road run: minor influence of age on performance

The importance of exercise in the elderly is widely recognized, but data on performances and drop-out in short running contests are lacking. This hinders stimulation and coaching of elderly persons in active aging. The aim of the study was to determine age-related changes in running performance in the most popular Dutch road run, and how this is influenced by gender, training, and increased participation rate over the last decade. This is a retrospective analysis of 194,560 participants of a 15-km run from 1995 to 2007. Multiple regression analysis of running time by age, gender, and training was performed. Trends in participation were examined by chi-square tests and ANOVA. Trends in running time and speed were examined by t tests. With aging, running time increased with 0.20% per year (P < 0.001). Running time was on average 13% (P < 0.001) shorter in men than in women and was 15.7% (P < 0.001) shorter in participants who trained on a regular basis. Decline in performance with age was 5.9% larger for men than women (P < 0.01) and 4.5% larger for trained than untrained participants (P < 0.01). Over the last decade, participation numbers increased most for elderly (≥60 years) and female participants, mean running performance declined with 9.9% (P < 0.001). Drop-out number was low at all ages (0.13–0.29%). It appears that aging has only minor negative influences on running performance, which can even be attenuated by training. Our data suggest that exercise by means of running is a safe and rewarding option for improvement of healthy and active aging.
