Choice correspondences for public goods

We consider collective choice problems where a group of agents has to decide on the location of a public facility in a Euclidean space. A well-known solution for such problems is the coordinatewise median of the reported votes and additional fixed ballots. Instead of adding ballots, we extend the median solution by allowing set-valued outcomes. This especially applies for location problems with an even number of agents.

Code‐switching and social identities in the Eastern Maroon community of Suriname and French Guiana1

Sociolinguistic research on Creole communities has so far focused mainly on the social and linguistic distinctiveness of Creoles and on their synchronic interaction with their European lexifier. To date, little work has been done on the stylistic make‐up of Creoles and on how these styles are employed in interactions to negotiate social identities and relationships. This paper investigates patterns of code‐switching between different Creole varieties in the Eastern Maroon community using Myers‐Scotton's markedness model. It demonstrates that such patterns are structurally similar to those found in other bilingual communities and function as an important resource for creating interactional meanings. Moreover, it shows that overall similar patterns of code‐switching convey partially different meanings due to their interaction with situational factors.     

Social Support,Unfulfilled Expectations,and Affective Well‐being on Return to Employment

We conducted a longitudinal study to investigate how social support from the partner is related to mothers' affective well‐being during their return to employment after maternity leave and whether expectations of that support have an additional impact. We differentiated four forms of support and their respective expectation discrepancies: emotional, instrumental, informational, and companionship. Further, we included the impact of meeting specific support expectations. A convenience sample of 288 women filled out questionnaires 2 weeks before reentry and then 1 month and 2 months afterward. Social support was associated with well‐being, with emotional support having the strongest positive impact. Informational and instrumental support either were not related or were negatively related to affective well‐being. Expectations had an additional influence but were inconsistently associated with affect. They became more important over time.     

Coaching von etablierten Professor/innen

Coaching for professors is increasingly gaining in importance at German universities. Especially the more established professors are challenging to reach. This article identifies and analyzes the established professors as a target group for business coaching in academia. Unique requirements concerning their management tasks and professional role are presented. Basic reasons for coaching of established professors are demonstrated in three characteristic case studies from practical experience.     

Motivating teammates: The leader’s choice between positive and negative incentives

Team leaders often provide incentives for cooperation. A challenging question is how different incentive schemes and their actual choice by the leader shape the team’s culture and contribute to the team’s success. To shed light on this issue we investigate how a leader chooses between rewards or punishment in an experimental team setting and how teammates’ contributions are influenced by this choice. Leaders show a clear initial preference for rewards, which diminishes over time in some teams. Leaders who observe more free-riders in their teams tend to switch to punishment incentives. A change from rewards to negative incentives results in an immediate and enduring increase in contributions. On the other hand, contributions show a decreasing trend in teams with a leader who sticks to rewards.     

A descriptive inquiry into the corporate communication profession in Europe

This paper explores the educational backgrounds, work activities, remuneration and job satisfaction of European communication professionals. Based on factor analysis of a sample of 1410 European communicators, five major work activities are identified: lobbying external constituencies, advising and reviewing policies, positioning the firm in the marketplace, and external and internal facilitation. Using analysis of variance between groups, we argue that some of the more technical work activities are predominantly conducted by female communication professionals, whereas managerial activities are predominantly performed by their male counterparts. As will be shown, while educational background does not differ between genders, salaries as well as job satisfaction do; likewise, there are differences in respect of educational background, salaries, and job satisfaction.

Younger Age at First Childbirth Predicts Mothers’ Lower Economic and Psychological Well-Being Later in Life

Age at first childbirth affects mothers’ economic and psychological well-being later in life. Using a gender and power framework, two studies examined the associations among age at first childbirth, employment status, perceived choice, and race/ethnicity as predictors of economic and psychological well-being in a sample of middle class, married mothers (Study 1) and a nationally representative sample of married mothers (Study 2). Results indicated younger age at first childbirth is associated with less choice; lower educational attainment; lower SES; greater household labor; greater perceived chore discrepancy; lower self-esteem; less life, work, and relationship satisfaction; but is unrelated to depression or work stress. There were differences by employment status and minimal differences by race/ethnicity. The findings suggest that negative economic and psychological outcomes later in life are related to having one’s first child at a younger age.     

‘It's good to live in Järva-Jaani but we can't stay here’: Youth and belonging in rural Estonia

In the broader context of post-socialist transition and rural decline, we examine the everyday lives of young people in rural Estonia. We focus in particular on key places of belonging for youths and the practices and experiences through which rural young people develop a sense of belonging to their local places. Our aim is to identify links between the everyday context and broader changes influencing young rural lives in Estonia. The findings indicate that in contrast to the mostly negative portrait that the statistics paint of rural Estonia, a focus on the everyday level reveals significant places and practices which can provide encouraging and supportive bases for young people to negotiate and respond to global changes. In addition, the results indicate that it is fruitful to focus on the everyday context, as a more nuanced picture of continuities and discontinuities associated with post-socialist transition may be revealed.     

Training effects on motor–cognitive dual-task performance in older adults

This systematic review investigated whether healthy older adults benefit from training interventions in motor–cognitive dual-task (DT) situations and which specific aspects of the intervention and/or task selection contribute to training benefits. Training effects were analysed with regard to the training programme (e.g., general ST or DT training) and task conditions (e.g., standing or walking, complexity of secondary cognitive task). Literature was searched via OVIDsp (Medline, EMBASE, PsycINFO). DT studies were included by the following criteria: (1) investigation of at least one motor task, (2) assessment of DT performance outcomes on standing or walking, (3) conduction of an intervention, and (4) investigation of older adults in an experimental–control group design or an old–young comparison. Thirteen studies met all inclusion criteria. Four types of interventions were identified: (1) general single-task (ST) motor training, (2) specific ST motor training, (3) general DT training, and (4) task-related (specific) DT training. For DT standing conditions only DT interventions improved motor performance, whereas DT walking also benefits by ST training. Most benefits on motor and cognitive performance seem to be reached by DT training interventions whereas a GST produced lowest effects. Thus, balance orientated motor and cognitive DT performance in healthy older adults can be improved by performance related exercises. Furthermore, to reach beneficial effects, it seems necessary that the training intervention includes a certain level of exercise load such as rising difficulties, appropriate intensity and duration, a certain level of task specificity, and variable task prioritization. The transfer of training effects into everyday situations needs to be further investigated.
