The tasks ahead of the ILO at its centenary

The principles that define the normative missions of the ILO – as set out in its Constitution and in the Declaration of Philadelphia – have lost none of their value or relevance. The circumstances in which those missions are carried out have, however, changed profoundly. The global organization of labour is currently witnessing major technical, environmental and institutional upheavals which, in turn, pose legal challenges for the ILO in each of these areas. The ILO's answer to these challenges should be based on three principles whose implementation is encompassed by its constitutional mandate: the principles of solidarity, economic democracy and social and environmental responsibility.

Using heuristics to find minimal unsatisfiable subformulas in satisfiability problems

In this paper, we propose efficient algorithms to extract minimal unsatisfiable subsets of clauses or variables in unsatisfiable propositional formulas. Such subsets yield unsatisfiable propositional subformulas that become satisfiable when any of their clauses or variables is removed. These subformulas have numerous applications, including proving unsatisfiability and post-infeasibility analysis. The algorithms we propose are based on heuristics, and thus, can be applied to large instances. Furthermore, we show that, in some cases, the minimality of the subformulas can be proven with these algorithms. We also present an original algorithm to find minimum cardinality unsatisfiable subformulas in smaller instances. Finally, we report computational experiments on unsatisfiable instances from various sources, that demonstrate the effectiveness of our algorithms.     

‘Becoming Angry When Another is Treated Fairly’: On Understanding When Own and Other's Fair Treatment Influences Negative Reactions

The present research examined across two experimental studies the impact of how fairly one's partner was treated on the experience of one's own negative emotions and intentions to display antisocial behaviours. Experiment 1 revealed that one's own feelings of anger and frustration were significantly higher when one's partner was treated fairly (i.e. receiving voice in the decision‐making procedure) relative to when one's partner was treated unfairly (i.e. receiving no voice), but only so when the interaction between oneself and the other was characterized by competitive interdependence (i.e. a zero‐sum gain in which a good performance by the other is negative for oneself and vice versa). The opposite pattern of results emerged in the cooperative interdependence condition (i.e. a good performance by the other is positive for oneself and vice versa). Experiment 2 (in which also the fairness of one's own treatment was manipulated) further showed that in the competitive interdependence condition own anger and frustration were higher when one's partner received voice and oneself did not relative to when the partner did not receive voice and oneself did. A similar effect was also obtained for intentions to display antisocial behaviour, which was mediated by negative emotions. These findings thus reveal that the other's procedurally fair treatment affects own responses differently as a function of the given goal interdependence and own treatment.     

The Many Faces of a Neutral Face: Head Tilt and Perception of Dominance and Emotion

Based on the premise that human head tilt is homologous to animal dominance displays, we hypothesized that when a head is bowed, the face should be perceived as submissive, sad, displaying inferiority emotions (i.e., shame, embarrassment, guilt, humiliation, and respect) and, paradoxically, as contracting the zygomatic major muscle. Conversely, a raised head should be perceived as more dominant and displaying greater superiority emotions (i.e., contempt and pride). We conducted two experiments showing 3-D models of faces to 64 participants. The results confirmed our hypotheses and also showed that a raised head connotes happiness. In addition, we found a significant influence of the actors' sex on participants' perception, such as a bias towards perceiving stronger upward contraction of the mouth in female than male actors when the head is tilted. We discuss these findings within the context of evolution and social behavior.     

Empirical Bayes and Adjusted Estimates Approach to Estimating the Relation of Mortality to Exposure of PM10

Forward Links to Citing Articles Retraction . Risk Analysis 25: 6, 1683
In the framework of the APHEIS program (Air Pollution and Health: A European Information System), a health impact assessment of air pollution in 26 European cities was performed for particles of an aerodynamic diameter less than or equal to 10 μm (PM₁₀). For short-term effects, it was based on overall estimates from the APHEA-2 project (Air Pollution and Health: A European Approach). These city-specific risk assessments require city-specific concentration-response functions, raising the question of which concentration-response is most appropriate. Estimates from city-specific models are more specific, but have greater uncertainty than those provided from multicity analyses. We compared several estimates derived from the city-specific analyses in cities that were part of the APHEA-2 project, as well as in a city that was not included in APHEA-2 but was part of the APHEIS project. These estimates were: the estimates from a local regression model, the adjusted estimates based on two significant effect modifiers identified through meta-regression models, and the city-specific empirical Bayes (shrunken) estimates and their underlying distribution. The shrunken and adjusted estimates were used to improve the estimation of city-specific concentration-response function. From these different estimates, attributable numbers of deaths per year were calculated. The advantages and limits of the different approaches are discussed through real data and in a simulation study.
