Burnout and Mental Health in Swiss Vocational Students: The Moderating Role of Physical Activity

Few studies have focused on burnout among vocational students. This study examined the association between burnout and mental health among 56 Swiss vocational students (29 males, 27 females, M = 18.1, SD = 1.2 years) and tested whether recommended levels of moderate‐to‐vigorous physical activity (MVPA) attenuate this relationship. Burnout was strongly associated with increased depressive symptoms and decreased levels of life satisfaction, mental toughness, and quality of sleep. Students above recommended levels of MVPA reported lower burnout and higher mental health. No significant moderator effects were observed. Symptoms of burnout were associated with increased mental health problems. Physical activity should be promoted to prevent burnout, because nearly half of the students did not meet MVPA recommendations.     

Balancing inclusion and exclusion among Somali migrants in Germany

We discuss the balancing acts of inclusion and exclusion by analysing how Somali migrants in Germany attempt to manoeuvre between various norms, individual interests and various social networks. Building on Glick Schiller and Caglar (2016), whose work on urban sociabilities emphasizes social relations in which people act as equals, we argue that ethnic (self-)identification is important as it serves as a basis for boundary-making and for bonding within and bridging and linking between groups. Thus, a focus on sociability and ethnic identification (as a category of praxis) can, in some cases, go hand in hand. Moreover, we argue that inclusion into local Somali communities, which is often discussed in public discourse as leading to exclusion from German society, helps to establish connections. Simultaneously, exclusion through racism can lead to (self-)isolation of Somalis, but also places pressure on younger Somalis in particular to forge alliances with non-Somali Germans to stabilize their situation. Balancing social inclusion and exclusion among Somali migrants in Germany therefore can have ambiguous and at times paradoxical outcomes.     

A note on a Bayesian order determination procedure for vectorautoregressive processes

This paper describes the posterior distribution of the order of a vectorautoregressive model and demonstrates its practical utility via some simulations.     

GEE estimation of the covariance structure of a bivariate panel data model with an application to wage dynamics and the incidence of profit-sharing in West Germany

We propose a generalized estimating equations (GEE) approach to the estimation of the mean and covariance structure of bivariate time series processes of panel data. The one-step approach allows for mixed continuous and discrete dependent variables. A Monte Carlo Study is presented to compare our particular GEE estimator with more standard GEE-estimators. In the empirical illustration, we apply our estimator to the analysis of individual wage dynamics and the incidence of profit-sharing in West Germany. Our findings show that time-invariant unobserved individual ability jointly influences individual wages and participation in profit sharing schemes.     

The role of cognitive load in effective strategic issue management

Firms have different ways of addressing issues emerging from outside their regular calendar-driven strategy processes. These practices tend to be unstructured, organization specific, and highly dependent on the characteristics of the strategic issues themselves. Building on three dimensions of cognitive load—intrinsic, germane, and extraneous cognitive load—we extend existing research on strategic issue management by showing how different team-level choices in strategic issue processing and organizational congestion interact in their effects on a firm's strategic issue management performance. Based on an in-depth analysis of all 92 strategic issue decisions in a large multinational firm during a three-year period, we find that organizational disturbances influence strategic issue initiation by top management, which in turn influences the quality of strategic issue management practices and subsequent performance outcomes. We conclude by providing recommendations for managers on how they can decrease the sensitivity of their companies' strategic issue systems to external disturbances.     

Wage Dynamics and Unemployment in Germany: Evidence from Regional Panel Data

A stylized fact of empirical work on the relationship of wages and unemployment using macro data for European countries is a combination of strong autocorrelation of wages and a significant negative long‐run relationship of wages and unemployment. However, this view is challenged by empirical work relying on regional or micro data providing evidence for an instantaneous adjustment of wages to variations in the level of unemployment. Exploiting regional panel data for West Germany, we show that, at least for the years 1990–94, regional and macro data mirror the same phenomenon. Our results are broadly consistent with the observed increase in the natural rate of unemployment in Germany.
