Open Innovation in Nonprofit Sports Clubs

This research paper investigates open innovation—that is, the use of purposive inflows and outflows of knowledge in order to innovate—in the context of nonprofit sports clubs, and is based on the content analysis of semi-structured interviews held with representatives of eleven sports clubs. The study develops a framework that describes open innovation activities in nonprofit sports clubs as facets of four superordinate dimensions, namely permeability of the club’s boundary, application and implementation of open innovation practices, managerial competencies, and the environmental and organizational surroundings in which the club operates. Within these dimensions, subordinate facets such as commitment of the club’s president and the strategic use of coopetitive environments explain how and why sports clubs are successful at implementing innovations and how their nonprofit status (e.g., volunteer work) contributes to (or is in conflict with) innovation. The findings provide implications for nonprofit organizations inside and outside the sports sector.     

Visual Dominance and Visual Egalitarianism: Individual and Group-Level Influences of Sex and Status in Group Interactions

This study investigated visual dominance and visual egalitarianism of men and women (N = 94; 17 teams) in team meetings at diverse workplaces. Two novel gaze-related measures were developed: (a) a group visual dominance ratio (group-VDR) assessing each member’s visual dominance vis-à-vis all other members, and (b) a gaze distribution index (GDI) assessing each member’s visual egalitarianism to all group members. Multilevel analyses were conducted to account for influences of the team members’ sex and status on the individual level and for influences of sex and status composition of the teams, and the team leaders’ sex on the group level. Results suggested that high-status individuals displayed more visual dominance than low-status individuals. The significant interaction of individuals’ sex and status indicated that the positive relationship of status and visual dominance applied particularly to women. The more women in a team, the more visual dominance was displayed. The team leader’s sex significantly influenced visual egalitarianism: Gaze distribution was less egalitarian when the team leader was male.     

Dealing with selective dropout in clinical trials

Clinical trials in severely diseased populations often suffer from a high dropout rate that is related to the investigated target morbidity. These dropouts can bias estimates and treatment comparisons, particularly in the event of an imbalance. Methods to describe such selective dropout are presented that use the time in study distribution to generate so‐called population evolution charts. These charts show the development of a distribution of a covariate or the target morbidity measure as it changes as a result of the dropout process during the follow‐up time. The selectiveness of the dropout process with respect to a variable can be inferred from the change in its distribution. Different types of selective dropout are described with real data from several studies in metastatic bone disease, where marked effects can be seen. A general strategy to cope with selective dropout seems to be the inclusion of dropout events into the endpoint. Within a time‐to‐event analysis framework this simple approach can lead to valid conclusions and still retains conservative elements. Morbidity measures that are based on (recurrent) event counts react differently in the presence of selective dropout. They differ mainly in the way dropout is included. One simple measure achieves good performance under selective dropout by introducing a non‐specific penalty for premature study termination. The use of a prespecified scoring system to assign a weight for each works well. This simple and transparent approach performs well even in the presence of unbalanced selective dropout.

Your House,Your Car,Your Education: The Socioeconomic Situation of the Neighborhood and its Impact on Life Satisfaction in Germany

This study deals with the impact of socioeconomic conditions and social integration into a local neighborhood on individual life satisfaction in Germany. While the majority of ecological studies to date are based on very broad neighborhood concepts, using large research units for defining neighborhood the present study contains micro-geographic information on a representative sample of private households in Germany, including features of their respective residential environments. The data was derived from the German Socio-Economic Panel (SOEP) study and enriched with data from the Micromarketing-Systeme and Consult GmbH (microm) for the years 2000–2006. Our analyses reveal neighborhood effects on various facets of life satisfaction. Controlling for several covariates at the household and individual level, life satisfaction increases when a person lives in a neighborhood with a higher socioeconomic status. In addition, the individual gap between a person’s economic status and the status of the neighborhood also affects individual well-being. However, when comparing with other neighborhood aspects, the strongest effects on individual life satisfaction have social networks.
