To be or not to be involved: a questionnaire-experimental view on Harsanyi’s utilitarian ethics

According to standard theory founded on Harsanyi (J Polit Econ 61:434–435, 1953; 63:309–321, 1955) a social welfare function can be appropriately based on the individual’s approach to choice under uncertainty. We investigate how people really do rank distributions in terms of welfare. According to Harsanyi, the evaluation can be done from the standpoint of an uninvolved external judge, a public official, for example, or by a person who knows that she holds one of the positions in society, with an equal chance for any of the available positions. Are these two structures to be viewed differently? We use a questionnaire experiment to focus on the two different interpretations of the Harsanyi approach. There are important, systematic differences that transcend the cultural background of respondents.     

Determinants of in-group bias: Is group affiliation mediated by guilt-aversion?

In-group favoritism in social dilemma situations is one of Social Identity Theory’s main findings. We investigate what causes the in-group bias: is it merely due to group affiliation or, alternatively, is guilt-aversion moderating the strength of in-group favoring? We induce group membership in a minimal group setting, observe in-/out-group transfers and elicit corresponding beliefs. According to our experimental data group affiliation affects beliefs and explains a substantial part of the bias. Evidence for guilt-aversion is found only when beliefs are elicited before actions.     

Framing human rights: exploring storytelling within internet companies

This article explores human rights storytelling within two of the dominant internet companies, Google and Facebook. Based on interview with company staff as well as analysis of publicly available statements, the article examines how human rights are framed, made sense of and translated into company norms, products, and governance structures. The paper argues that the companies’ framing in many respects resembles that of the United States’ online freedom agenda, celebrating the liberating power of the internet and perceiving human rights as primarily safeguards against repressive governments. The companies see freedom of expression as part of their DNA and do not perceive any contradiction between this standard and business practices that may impact negatively on users’ freedom of expression, such as terms of service enforcement. Likewise, there is no sense of conflict between the online business model and their users’ right to privacy.     

(Sub) Optimality and (non) optimal satisficing in risky decision experiments

We implement a risky choice experiment based on one-dimensional choice variables and risk neutrality induced via binary lottery incentives. Each participant confronts many parameter constellations with varying optimal payoffs. We assess (sub)optimality, as well as (non)optimal satisficing by eliciting aspirations in addition to choices. Treatments differ in the probability that a binary random event, which are payoff—but not optimal choice—relevant is experimentally induced and whether participants choose portfolios directly or via satisficing, i.e., by forming aspirations and checking for satisficing before making their choice. By incentivizing aspiration formation, we can test satisficing, and in cases of satisficing, determine whether it is optimal.     

$$D_s$$-optimality in copula models

Optimum experimental design theory has recently been extended for parameter estimation in copula models. The use of these models allows one to gain in flexibility by considering the model parameter set split into marginal and dependence parameters. However, this separation also leads to the natural issue of estimating only a subset of all model parameters. In this work, we treat this problem with the application of the \(D_s\)-optimality to copula models. First, we provide an extension of the corresponding equivalence theory. Then, we analyze a wide range of flexible copula models to highlight the usefulness of \(D_s\)-optimality in many possible scenarios. Finally, we discuss how the usage of the introduced design criterion also relates to the more general issue of copula selection and optimal design for model discrimination.     

Contagion of Anxiety Symptoms Among Adolescent Siblings: A Twin Study

This study examined whether social contagion of anxiety symptoms is present between siblings during early adolescence and whether this process is moderated by sex, relationship quality, and zygosity. Based on 634 monozygotic and dizygotic twins (336 females) assessed in Grades 6 and 7, anxiety symptoms and sibling relationship quality were measured with self‐report questionnaires. The predictive association of the co‐twin's level of anxiety with adolescents' own increased anxiety 1 year later was only observed in same‐sex twin dyads (monozygotic and dizygotic) and was higher for those who perceived a higher level of relationship quality with their co‐twin. Raising awareness of a possible sibling contagion of anxiety may be useful for preventing the development of anxiety symptoms in youth.     

Dementia: challenges for social work education in Europe

ABSTRACT

Dementia has been identified as a global challenge across the spectrum of health and social care (World Health Organisation. (2012) Dementia: A public health priority. Geneva: WHO). This paper will explore the implications of this for social work education and the challenges it poses. There is a lack of this focus on social work with older people and people with dementia (pwd) in social work education. Based on calls for an infusion of content on ageing and dementia in social work curricula, paper proposes that we should adopt a person-centred philosophy alongside gerontological social work competencies to achieve this. The specific aim of this paper, therefore, is to explore how we can use these ideas as teaching tools to engage social work students in the discourse on dementia and to develop appropriate skills to work with pwd, their families and carers.     

The adoption of multiple certification standards: perceived performance implications of quality,environmental and health & safety certifications

This study assesses the combined impact of multiple certifications (i.e. ISO 9001, ISO 14001, OHSAS 18001) on perceived performance dimensions related to quality, environmental and occupational health and safety. Using survey data collected from 59 Irish manufacturing plants in 2014, we employed MANCOVA and regression analysis to test our proposed hypothesis. The results suggest that companies that are simultaneously ISO 9001, ISO 14001 and OHSAS 18001 certified are significantly better performers with regard to environmental and occupational health and safety compared to companies without multiple certifications. However, from a perceived quality performance perspective, having these multiple certifications doesn’t seem to be an effective performance improvement tool.     

Co-morbidity Between Gambling Problems and Depressive Symptoms: A Longitudinal Perspective of Risk and Protective Factors

In both adolescents and adults, gambling problems and depressive symptoms co-occur and share some common risk factors (e.g., impulsivity and socio-family risk). However, little is known about (1) the developmental course of the co-morbidity of these problems; (2) variables that may moderate the effect of these common risk factors on gambling problems and depressive symptoms. Of specific interest could be individuals’ social relationships with significant others such as parents and friends, because research shows that they moderate the effect of other risk factors on gambling problems and depressive symptoms. The goals of this study were to: (a) identify developmental pathways for gambling problems and depressive symptoms, with a focus on co-morbidity; (b) assess the moderating effect of relationship quality with parents and friends on the link between common risk factors and the trajectories of gambling problems and depressive symptoms. Study participants were 878 males. Predictors were assessed during childhood and adolescence and gambling problems and depressive symptoms were assessed in late adolescence and young adulthood. Latent class analysis revealed four distinct joint trajectories of gambling problems and depressive symptoms. Subsequent logistic regression revealed that impulsivity predicted membership in all pathogenic trajectories, and quality of the relationship with parents predicted membership in depressogenic trajectories. In addition, we found that the membership in the comorbid trajectory can be predicted by an interaction between friendship quality and socio-family risk.     

Of River Linkage and Issue Linkage: Transboundary Conflict and Cooperation on the River Meuse

Abstract

It is a truism in mainstream International Relations that issue linkage promotes regime formation and integration. The present article applies this idea to the transboundary lower river Meuse and finds its history of integration to be a tortuous one. Contextual political factors have at times promoted integration, at times fragmentation. The path towards regional integration, then, has not been not linear, but has consisted of conflict and cooperation, of (Meuse–Scheldt) river linkage and issue linkage, but also counterlinkage and non-linkage. Clearly linkage is not necessarily positive. I will argue that this does not need to be problematic, but suggest accepting more complexity in the analysis of river integration. I propose a way to create some order in the many available concepts of linkage to map out the role of linkage in integration.
