Annoyance Caused by Environmental Noise: Elements for Evidence-Based Noise Policies

Because effects of environmental noise do not require extremely high or long exposures, they occur, with different degrees of intensity, in a substantial part of the world population, especially in areas with a dense population and dense transportation networks. As a consequence, noise is a global issue that continues to detract from sustainable development. This article attempts to contribute to evidence-based noise policies by providing a review and systematization of noise-effects modeling and findings. The results presented can be used in noise abatement policy to find the best practical ways of reducing noise-induced effects through the reduction of noise exposure. At present, it is possible to calculate noise maps showing the exposures to noise in residential areas. With the relationships between exposure and effects as presented here, these can be translated into estimates of the number of people affected. Estimates of effects can be made on the basis of existing noise exposures, but also on the basis of scenarios for future noise levels, so that the consequences of different scenarios can be explored and decisions with respect to noise abatement measures can be optimized. Such an evidence-based approach may be instrumental in reducing the worldwide burden of environmental noise.     

Indexation of public pension benefits on a legal basis: Some experiences in European countries

Legal provisions concerning indexation of social benefits to wage or price movements are a common feature of social security systems in European countries. At the moment, there is a lively debate in some countries whether such mechanisms should be continued in a modern, flexible Welfare State. This paper analyses whether indexation provisions are effective, i.e. whether they limit the range of political decision-making on benefit adjustments. Evidence from Germany, the United Kingdom, France and the Netherlands shows that trends in benefit adjustment are quite pronounced in time and comparable between countries, indicating that changing economic circumstances may be of more importance to changes in benefit levels than the precise contents of indexation clauses. Also, indexation clauses have frequently been adjusted to changing circumstances. Nevertheless, it appears that the incorporation of indexation provisions in the law still has a strong symbolic meaning.     

The institutional logics of love: measuring intimate life

Building on a long tradition of measuring cultural logics from a relational perspective, we analyze a recent survey of American university students to assess whether institutional logics operate in the lived experience of individuals. An institutional logic is an analytic troika of object, practice, and subject linked together through dually ordered systems of articulations. Using the formal method of correspondence analysis (MCA) we identify two latent dimensions that order physical, verbal, emotional, categorical, and moral practices of and investments in love. We take these dimensions as evidence of an institutional logic. The dominant first dimension is organized through talk of love, non-genital physical intimacies, and affective investment. It has no sexual specificity. The subsidiary second dimension is organized through moral investment and it has a genital sexual specificity. There is little difference between women and men, either in the way these dimensions are organized or in the location of men and women within these dimensionalized spaces. We find that romantic love has a situated material effect in terms of increasing the probabilities of orgasm.     

The demise of the population regulation controversy?

For many decades a controversy in population dynamics theory has been raging concerning whether or not populations are regulated by density dependent factors, without reaching a satisfactory conclusion. It is suggested that this failure to solve the problem is due to asking the wrong question and it is suggested that this controversy should be buried and forgotten.     

The Role of Group Member Affect in the Relationship between Trust and Cooperation

It is widely acknowledged that trust greatly affects work group functioning. Whereas trust may facilitate cooperation, distrust may impede it. Insight into when distrusters may be prompted to cooperate may therefore be of importance. Empirical studies point to several moderators of the effect of trust on cooperation. Unfortunately, these studies largely ignored the potential role of group member affect. Our study shows that group members' affective displays (particularly the activation level of the displays) have a substantial impact on the relationship between trust and cooperation. First, a scenario experiment (n=80) revealed that low trusting individuals were more willing to cooperate when confronted with group members who display high (versus low) activation affective states, whereas for more high trusting individuals cooperation was not contingent on other group members' affective displays. Second, a laboratory experiment (n=78), employing a social dilemma paradigm, replicated these findings and indicated that this effect is explained by the extent to which others are expected to cooperate. The discussion focuses on theoretical implications and managerial ramifications. Our study testifies to the significant role that affect may play in keeping up cooperation in organizations and work groups when trust is withering.
