Woodland fragments in urban landscapes are important bat areas: an example of the endangered Bechstein’s bat Myotis bechsteinii

Urban Ecosystems - Urban areas are increasing globally causing fragmentation and loss of habitats for many forest dwelling species. At the same time new habitats are created, which may be exploited...     

Public/Private Pension Mix,Income Inequality and Poverty among the Elderly in Europe: An Empirical Analysis Using New and Revised OECD Data

Prior studies have suggested that higher public pensions are associated with lower income inequality among the elderly, whereas the reverse is true for private pensions. Van Vliet et al. ( 2012 ) empirically test whether relative shifts from public to private pension schemes entail higher levels of income inequality among the elderly using panel data from the OECD SOCX and the EU‐SILC databases. Contrasting earlier empirical studies using either cross‐sectional or time‐series data, they do not find evidence that shifts from public to private pension provision are associated with higher levels of income inequality or poverty among the elderly. The aim of the current article is to extend the analysis of Van Vliet et al. by: (1) adding additional countries; (2) adding additionally available years; and (3) using revised OECD SOCX data. In contrast to Van Vliet et al., we find that a greater relative importance of private pensions is associated with higher levels of income inequality and poverty among the elderly. A central explanation of the difference in conclusions stems from the revision of OECD SOCX data.     

Zu aktivierenden Gefühlspraktiken und -semantiken von MitarbeiterInnen deutscher Arbeitsämter

The paper tries to fill a gap in the existing sociological literature on emotions by investigating how public employment agents actually deal with their clients emotionally under a regime of activation. The results are based on interviews and non-participant observations in German employment agencies. It is argued that there are two crucial forms of emotional practices in the interaction of agents with their unemployed clients: first, emotional evaluations of the situation and the present client, and second, empathy with the client. Furthermore, the empathy of staff members changes in the younger generations of agents from political to individualized ways of solidarity. Finally, the paper will show that the changing emotional practices are interconnected with changes of the welfare state and policies of activation, but also with general cultural changes.     

Motives and Decisions for and Against Having Children Among Nonheterosexuals and the Impact of Experiences of Discrimination,Internalized Stigma,and Social Acceptance

Same-sex parents are increasingly a topic of public discourse. A growing number of homosexuals openly speak about their desire to have children or are already living together in different family constellations. The current study examined the decisions for or against having children and the motivations behind those decisions among nonheterosexuals living in Germany. A sample of 1,283 nonheterosexuals participated by means of an online survey. As some nonheterosexual individuals do not identify themselves with a male or female gender identity, a third category, “gender different,” was generated. Motives for (not) having children, perceptions of social acceptance, experiences of discrimination in relation to one's sexual orientation, and levels of internalized stigma were taken into account regarding their influence on the decision about parenthood. Most respondents (80%) reported that they did not have children. However, among this group, 43% stated that they had decided to have children later in their lives, 24% were undecided, and 11% had already decided against having children. The most important influences on the decision of whether to have children were respondents’ age and their desire for emotional stabilization. Negative experiences as a result of sexual orientation and internalized stigma had no impact on the decisions regarding parenthood.     

Risk patterns in drug safety study using relative times by accelerated failure time models when proportional hazards assumption is questionable: an illustrative case study of cancer risk of patients on glucose‐lowering therapies

Observational drug safety studies may be susceptible to confounding or protopathic bias. This bias may cause a spurious relationship between drug exposure and adverse side effect when none exists and may lead to unwarranted safety alerts. The spurious relationship may manifest itself through substantially different risk levels between exposure groups at the start of follow‐up when exposure is deemed too short to have any plausible biological effect of the drug. The restrictive proportional hazards assumption with its arbitrary choice of baseline hazard function renders the commonly used Cox proportional hazards model of limited use for revealing such potential bias. We demonstrate a fully parametric approach using accelerated failure time models with an illustrative safety study of glucose‐lowering therapies and show that its results are comparable against other methods that allow time‐varying exposure effects. Our approach includes a wide variety of models that are based on the flexible generalized gamma distribution and allows direct comparisons of estimated hazard functions following different exposure‐specific distributions of survival times. This approach lends itself to two alternative metrics, namely relative times and difference in times to event, allowing physicians more ways to communicate patient's prognosis without invoking the concept of risks, which some may find hard to grasp. In our illustrative case study, substantial differences in cancer risks at drug initiation followed by a gradual reduction towards null were found. This evidence is compatible with the presence of protopathic bias, in which undiagnosed symptoms of cancer lead to switches in diabetes medication. Copyright © 2015 John Wiley & Sons, Ltd.     

Global Civil Society and Its Discontents

According to enthusiasts the concept of global civil society is spreading rapidly and becoming pivotal to the reconfiguring of the statist paradigm. However, critics have recently grown more numerous and outspoken in opposition to the term claiming that it is actually perpetuating statism by grafting the idea of civil society onto the global by way of an unhelpful domestic analogy. This paper examines the role the concept is playing in perpetuating/reconfiguring statism. First it summarizes current criticism by identifying three basic accusations: the ambiguity of the term, the “domestic fallacy,” and the undemocratic effects of using it. Second, these criticisms are considered in turn and it is concluded that all three points relate, ultimately, back to the failure of the critics themselves and some global civil society theorists to move beyond a state-centered framework of interpretation. In the final section it is shown how global civil society discourse is beginning to move not only the concept of “civil society” away from its state-centred historical meanings, but also how it is contributing to changing the content of the concept of “the global.”

Bonuszahlungen an Geschäftsführungen: Wodurch werden Gerechtigkeitsurteile von Erwerbstätigen beeinflusst?

Managerial compensation in large companies is subject to many critical concerns; this holds particularly for bonus payments. Empirical evidence shows that nearly three quarter of the German population perceive managers’ incomes as unfairly high. Based on an own survey, we examine what drives fairness perceptions of bonus payments for managers: When do employees assess bonus payments for managers within their own company as unfairly high? Under which conditions do they accept high bonus payments? The analyses show that acceptance decreases with the estimated amount of bonus paid. It increases, however, if aspects of procedural and distributive justice are taken into account.     

Optimum designs in complete two-way layouts

In the usual two-way layout of ANOVA (interactions are admitted) let nij ? 1 be the number of observations for the factor-level combination(i, j). For testing the hypothesis that all main effects of the first factor vanish numbers $\text{n}{}^1\text{ij}$ are given such that the power function of the F-test is uniformly maximized (U-optimality), if one considers only designs (nij) for which the row-sums ni are prescribed. Furthermore, in the (larger) set of all designs for which the total number of observations is given, all D-optimum designs are constructed.
