Bewältigungs- und Aneignungsmuster staatlich geförderter Beschäftigung bei ehemaligen Langzeitarbeitslosen

The article analyses the experiences made in publicly subsidized employment by long-term-unemployed in theoretical and empirical perspectives. The heterogeneity of the investigated population requires a differentiation between various types of personal employment histories as well as the examination of patterns of coping with subsidized employment from a differential perspective: Only a subgroup of the target-group share the notions of normality on which its construction is based. Furthermore, the wage subsidy can fulfill different functions with regard to the recipient’s personal employment history. Finally, problematic employment situations can result in the termination of a subsidized employment relationship. Since heterogeneous groups of persons can be affected by a permanent exclusion from the labour market, it seems problematic to tackle the problems connected with this situation by applying a single labour market measure.     

Rethinking the Foundations of Sustainability Measurement: The Limitations of the Environmental Sustainability Index (ESI)

The objective of sustainability measurement is to move environmental decision making toward more rigorous, quantitative and empirical foundations. One of the most comprehensive attempts to lay out the foundations for sustainability measurement has been offered by the Environmental Sustainability Index (ESI). This paper aims to advance the science of sustainability measurement by assessing the validity and reliability of this composite index in order to provide new insights for future indicator development. The architecture of the ESI is validated against the Pressure-State-Response (PSR) model, after which an exploratory factor analysis is conducted to reveal the latent structure of the index. Further, the performance of the ESI is tested in cross-national regression models. The results indicate a lack of consistency with the well established PSR model and a potential bias towards economically developed countries grounded in the architecture and weighting mechanism of the index. A re-weighted index (Equivalised ESI) is constructed, resulting in a new ranking of countries’ sustainability. The Equivalised ESI improves the measurement qualities of the index, and in so doing actually reinforces the rich-country bias of the ESI. Put differently, the Equivalised ESI brings the deficiencies of the original ESI to the fore. This paper illustrates that there are serious conceptual problems and validity concerns with defining the ESI as a sustainability measure. Taken together, the findings reinforce the need to reconsider future foundations of sustainability measurement in order to ensure that it is clear both what is being measured and how well.     

The Influence of Commitment,Trust, Satisfaction,and Involvement on Donor Retention

Due to certain developments in the business of fundraising, there exists an increasing necessity to theoretically and empirically analyze donor behavior. This article examines donor retention from the donor’s point of view. It concretizes four antecedents and their relationships with one another. The influencing variables investigated are commitment, trust, satisfaction, and involvement. The empirical analysis conducted in Germany among donors of four representative social non-profit organizations shows that all variables have an influence on donor retention, although some of them only indirectly.     

Correlated variables in regression: Clustering and sparse estimation

We consider estimation in a high-dimensional linear model with strongly correlated variables. We propose to cluster the variables first and do subsequent sparse estimation such as the Lasso for cluster-representatives or the group Lasso based on the structure from the clusters. Regarding the first step, we present a novel and bottom-up agglomerative clustering algorithm based on canonical correlations, and we show that it finds an optimal solution and is statistically consistent. We also present some theoretical arguments that canonical correlation based clustering leads to a better-posed compatibility constant for the design matrix which ensures identifiability and an oracle inequality for the group Lasso. Furthermore, we discuss circumstances where cluster-representatives and using the Lasso as subsequent estimator leads to improved results for prediction and detection of variables. We complement the theoretical analysis with various empirical results.     

Leaders as role models: Effects of leader presenteeism on employee presenteeism and sick leave

ABSTRACT

There is a broad consensus that associations exist between leadership behaviour and employee health. However, much less is known about potential mediating processes underlying links between specific leader behaviours, for instance presenteeism (i.e. working while being ill), and indicators of employee health, such as sick leave. Integrating theories of social information processing, social learning, and the allostatic load hypothesis, we propose that employee presenteeism mediates the positive association between leader presenteeism and employee sick leave. This hypothesis was tested with a multilevel mediation model using three-wave longitudinal data from 74 leaders and their 412 team members across a time period of 22 months. As hypothesised, leader presenteeism had a positive effect on employee presenteeism which, in turn, had a positive effect on employee sick leave, controlling for baseline measures of employee presenteeism and sick leave, as well as employee general health status, shared workload and job autonomy, and demographic characteristics. Additionally, leader presenteeism had a positive indirect effect on employee sick leave through employee presenteeism. These results contribute to the occupational health psychology literature by suggesting that leader health-related behaviour can have consequences for employee health-related behaviour and employee health.     

A Case Study on the Informational Efficiency of Markets: The Market for Horse Racing in Australia

This paper describes a study of the informational efficiency of the thoroughbred horse racing market in Australia. It is based on the theory of stock market efficiency which explains the process by which information becomes reflected in share prices. In this paper, the theory is applied to the thoroughbred horse racing market to determine the predictive accuracy of alternative informative sources. The results obtained from the study are consistent with the underlying theory:(i) aggregated information (as reflected in a consensus of opinions) is a more accurate prediction of success than less information (as reflected in individual opinions), and;(ii) the most recent information (as reflected in race-time betting odds, known as starting prices) has greater predictive ability than less recent information (as reflected in an earlier consensus of opinions).The study examines predictive accuracy in a gambling context, but does not consider the profitability of alternative prediction processes.     

The Termination of Public Organizations: Theoretical Perspectives to Revitalize a Promising Research Area

While many studies deal with comparative public sector reform, the fundamental question of whether and to what extent states are actually able to abolish parts of their administrative structure remains untackled. Despite some efforts to solve this puzzle, the topic remains underestimated. This article identifies the main conceptual and theoretical problems associated with existent research on the termination of public organizations. Furthermore, the article systemizes various causal factors of termination into two broad dimensions: “organizational stickiness” and “political incentives.” Taken together, these constitute a typology, which is able to guide future empirical investigation of the termination of public organizations.
