Comparing families of dynamic causal models

Mathematical models of scientific data can be formally compared using Bayesian model evidence. Previous applications in the biological sciences have mainly focussed on model selection in which one first selects the model with the highest evidence and then makes inferences based on the parameters of that model. This "best model" approach is very useful but can become brittle...

Striatal prediction error modulates cortical coupling

Both perceptual inference and motor responses are shaped by learned probabilities. For example, stimulus-induced responses in sensory cortices and preparatory activity in premotor cortex reflect how (un)expected a stimulus is. This is in accordance with predictive coding accounts of brain function, which posit a fundamental role of prediction errors for learning and adaptive behavior...

Lateralisation of self-esteem: An investigation using a dichotically presented auditory adaptation of the Implicit Association Test

Introduction: Self-esteem is one of the most prominent and influential constructs in psychological science, yet very few neuropsychological/neuroscientific investigations have been undertaken in this area of research. The current study investigated the possibility of hemispheric lateralisation of self-esteem.
Methods: By creating an auditory version of the Implicit Association...

Do international labor standards contribute to the persistence of the child-labor problem?

In recent years, a number of governments and consumer groups in rich countries have tried to discourage the use of child labor in poor countries through measures such as product boycotts and the imposition of international labor standards. The purported objective of such measures is to reduce the incidence of child labor in developing countries and thereby improve children’s welfare...

Interaction of natural survival instincts and internalized social norms exploring the Titanic and Lusitania disasters

To understand human behavior, it is important to know under what conditions people deviate from selfish rationality. This study explores the interaction of natural survival instincts and internalized social norms using data on the sinking of the Titanic and the Lusitania. We show that time pressure appears to be crucial when explaining behavior under extreme conditions of life and...

Academic Rankings and Research Governance

Academic rankings today are the backbone of research governance, which seem to fit the aims of “new public management” on the one side and the idea of the “republic of science” on the other side. Nevertheless rankings recently came under scrutiny. We discuss advantages and disadvantages of academic rankings, in particular their unintended negative consequences on the research process...

Is the Welfare State Sustainable? Experimental Evidence on Citizens' Preferences for Redistribution

The sustainability of the welfare state ultimately depends on citizens’ preferences for income redistribution. They are elicited through a Discrete Choice Experiment performed in 2008 in Switzerland. Attributes are redistribution as GDP share, its uses (the unemployed, old-age pensioners, people with ill health etc.), and nationality of bene?ciary. Estimated marginal willingness to...

Der Minergie-Boom unter der Lupe : Eine Marktanalyse der ZKB

Der Minergie-Standard ist seit der Lancierung 1998 auf erfolgreichem Kurs. Insgesamt wurden bisher rund 15 000 Gebäude nach Minergie, Minergie-P oder Minergie-Eco gebaut oder modernisiert. Damit hat Minergie im internationalen Vergleich die Nase vorn: Mit 15 Prozent Anteil am Neubau ist Minergie weltweit das wohl am besten umgesetzte Energie- oder Nachhaltigkeitslabel. Vor diesem...

What determines the inclusion in a sustainability stock index? A panel data analysis for European firms

This paper empirically examines the determinants of the inclusion of European firms in the Dow Jones Sustainability World Index and the Dow Jones Stoxx Sustainability Index. While a restricted econometric analysis implies a positive effect of corporate financial performance, this impact becomes ambiguous in more flexible panel probit models. Our estimation results therefore...

Ten simple rules for dynamic causal modeling

Dynamic causal modeling (DCM) is a generic Bayesian framework for inferring hidden neuronal states from measurements of brain activity. It provides posterior estimates of neurobiologically interpretable quantities such as the effective strength of synaptic connections among neuronal populations and their context-dependent modulation. DCM is increasingly used in the analysis of a wide...
