Determinanten der Lebensqualität psychisch kranker Personen

Not only chronic mental disease, but also psycho-social factors limit the quality of life (QoL) of mentally ill persons. From three theoretical explanation models of QoL — the medical model, labeling theory, and stress process model — we deduced three hypotheses. To test our hypotheses, we re-analysed data from the study “Social integration and quality of life of mentally ill people”. Data were derived from structured interviews with 305 in-patients in psychiatric institutions in the Canton of Zurich (Switzerland), and completed with few informations from their doctors’ files. Various QoL dimensions entered the statistical analyses as dependent variables. Results indicate varied explanation power of the models under investigation depending on the dimension of QoL: psychic symptoms highly influence the health-related QoL, but have only small effects on social and material QoL. Social as well as material QoL are strongly influenced by social support as well as, though to a lesser extent, by life stress events. Chronification of mental illness and perceived discrimination because of the mental disease indirectly affect QoL through reduced social support and increased psychic symptoms. From our results we conclude that social integration and rehabilitation of mentally ill people require a bio-psycho-social treatment approach.     

A learning collaborative approach to training school-based health providers in evidence-based mental health treatment

Collaborative care models among pediatric primary care and child and adolescent mental health providers are increasingly emphasized to improve quality of and access to mental health services. The current case example of a multi-site clinical training opportunity in school-based collaborative care settings illustrates the success of a learning collaborative approach to improve children's mental health care in schools. Quality improvement data from participating sites indicated an increase in use of evidence-based practices (i.e., “core skills”) and an improvement in quality service delivery indicators for children's mental health (i.e., screening, risk assessment, diagnostic processes, associated diagnostic coding, use of core skills, associated procedural coding, and follow-up assessment and referral) over time. Clinician self-report and chart review data are supplemented by qualitative data from site leader interviews conducted following completion of the project. Implications for mental health workforce development to improve the quality of care to children and adolescents in schools and other community mental health settings are discussed.     

PEOPLE AND PLACES: WELFARE REFORM AND THE SEPARATE EFFECT OF CASELOAD CHARACTERISTICS AND LOCAL CONDITIONS

An intersectional feminist approach informs qualitative content analyses of gender and trade advocacy websites in order to gain insights into the relation between trade liberalization and women in the global South. Findings include these websites are advocating for more representation in policymaking institutions spanning the global and local divide; emphasizing the need for networks within and outside institutions; and advocating for alternatives to free trade. The diverse and often contradictory understandings and strategies displayed by these websites arise from concern with giving voice to local needs and women in the South. These findings underscore the contributions a feminist approach makes to global political economy research by bringing attention to the heterogeneity of global political economic processes and power relations, and providing insights as to how global counter-hegemonic efforts can embrace diversity rather than being homogenizing.     

DO LAB EXPERIMENTS MISREPRESENT SOCIAL PREFERENCES? THE CASE OF SELF‐SELECTED STUDENT SAMPLES

Social preference research has received considerable attention among economists in recent years. However, the empirical foundation of social preferences is largely based on laboratory experiments with self‐selected students as participants. This is potentially problematic as students participating in experiments may behave systematically different than nonparticipating students or nonstudents. In this paper we empirically investigate whether laboratory experiments with student samples misrepresent the importance of social preferences. Our first study shows that students who exhibit stronger prosocial inclinations in an unrelated field donation are not more likely to participate in experiments. This suggests that self‐selection of more prosocial students into experiments is not a major issue. Our second study compares the behavior of students and participants recruited from the general population in a trust experiment. In general, we find very similar behavioral patterns for the two groups, but nonstudents make significantly more generous repayments suggesting that results from student samples might be seen as a lower bound for the importance of prosocial behavior.     

Sustainable Development and Capabilities for the Polar Region

The paper develops a sustainable development framework for individual and collective capabilities in mixed subsistence and wage-based economies. We apply this framework to such regions of the Arctic and evaluate interactions and conflicts between two sectors of the mixed economy and between current and future generations of Arctic inhabitants. A recent Arctic Social Indicators Report published by the Arctic Human Development Report (AHDR) Task Force recognizes the importance of the mixed economy in the Arctic and aims to integrate collective assets, as well as individual assets in order to understand the human development in the Arctic. Yet due to its concerns of comparability of social development and data availability across the whole Arctic region (of which some parts do not have the similar population structure), its proposed indicators are not capable of covering the social development of predominantly indigenous regions of the North. We emphasize the importance of tracking collective capabilities, as well as individual capabilities to sustain community development. In addition we suggest that environmental sustainability, which is ignored by the AHDR Task Force, has to be integrated with social development as environmental deterioration significantly influences the social well-being and cultural stability of traditional inhabitants of the Arctic. We critically review the proposed indicators of the AHDR Task Force and make supplementary and alternative suggestions.     

A Note on Job Tenure and Collective Contracts

Abstract. This paper analyses the relationship between individual tenure and the application of collective contracts at the firm level under the specific institutional settings in Germany. The empirical approach is based on a multilevel model and a linked employer–employee data set for the years 1990, 1995, and 2001. The main result is that elapsed tenure is longer in firms applying collective contracts than in companies with individual wage setting: workers in firms with collective contracts benefit not only from higher wages, but also from higher job stability. Furthermore, we find no significant changes in mean tenure during the 1990s as well as stable differences across wage‐setting regimes.     

Regularized Gaussian belief propagation

Belief propagation (BP) has been applied in a variety of inference problems as an approximation tool. BP does not necessarily converge in loopy graphs, and even if it does, is not guaranteed to provide exact inference. Even so, BP is useful in many applications due to its computational tractability. In this article, we investigate a regularized BP scheme by focusing on loopy Markov graphs (MGs) induced by a multivariate Gaussian distribution in canonical form. There is a rich literature surrounding BP on Gaussian MGs (labelled Gaussian belief propagation or GaBP), and this is known to experience the same problems as general BP on graphs. GaBP is known to provide the correct marginal means if it converges (this is not guaranteed), but it does not provide the exact marginal precisions. We show that our adjusted BP will always converge, with sufficient tuning, while maintaining the exact marginal means. As a further contribution we show, in an empirical study, that our GaBP variant can accelerate GaBP and compares well with other GaBP-type competitors in terms of convergence speed and accuracy of approximate marginal precisions. These improvements suggest that the principle of regularized BP should be investigated in other inference problems. The selection of the degree of regularization is addressed through the use of two heuristics. A by-product of GaBP is that it can be used to solve linear systems of equations; the same is true for our variant and we make an empirical comparison with the conjugate gradient method.     

Risky investment decisions: How are individuals influenced by their groups?

We investigate the effect of group versus individual decision-making in the context of risky investment decisions in which all subjects are fully informed of the probabilities and payoffs. Although there is full information, the lottery choices pose cognitive challenges so that people may not be sure of their expected utility-maximizing choice. Making such decisions in a group context provides real-time information in which group members can observe others’ choices and revise their own decisions. Our experimental results show that simply observing what others in the group do has a significant impact on behavior. Coupling real-time information with group decisions based on the median value, i.e., majority rule, makes the median investment choice focal, leading people with low values to increase investments and those with high values to decrease investments. Group decisions based on the minimum investment amount produce more asymmetric effects.     

Digitalisierung und Konvergenz von Online- und Offline-Welt

The increasing diffusion of mobile phones with internet access (Smartphones) enables more and more consumers to use the mobile internet. In addition, there is a continuing integration of location-based services (LBS). By means of Global Positioning Systems or WiFi-triangulation LBS provide context-aware information to consumers. This leads to a convergence of online and offline worlds. The usage of LBS delivers additional information to consumers (e.g. alternative offers or detailed product information). Therefore LBS do have an influence on consumer behavior. Particularly during the search process, information about prices or geographic distances, that are relevant for the purchase, are of importance. This study analyzes the relevance of location-based internet search empirically. Search costs are estimated on an individual level in a choice-based conjoint analysis using two different products. As a result, location-based internet search is considered to be very relevant for search and influential on consumer behavior. The study shows different consumers preferences and different search costs depending on the product. To conclude the study, the implications are discussed. The major contribution of this study is that it shows that offline and online search do have a mutual impact on each other. Furthermore, search costs are measured in a mobile context.     

The Limits of Monetizing and Paying for Volunteering in Eldercare: A Behavioral-Economic Approach

The monetary value of informal eldercare in the family and voluntary sector has drawn much attention as it concerns a resource of welfare governments and nonprofit organizations try to activate via cash benefits. Studies addressing the issue in order to assess the economic impact of non-market activities and the willingness to accept financial rewards have largely ignored differences in the utility function of caregivers. Applying a behavioral-economic approach, we report a profound and formerly unobserved distinction between care in the household and non-household care for a family member or in a voluntary framework: whereas caregivers within the household perceive care as a burden and a positive shadow price arises, in the non-household context—and particularly in the volunteering case–care extends well-being and leads to negative shadow prices. The results show that non-market activities can only be measured in monetary terms to a limited extent and contribute to explaining the boundaries of monetary incentive policies.
