The EU has become a loose kind ofsocial federation, a fact that has not been adequately taken into account due to the peculiarities ofthe Maastricht strategy for monetary integration. Yet, a new approach to the economic theory offederalism is required ifone wants to analyze the most pressing issues ofEU social policy. The social insurance view of redistribution and stabilization provides for such an approach. This view supports laboratory federalism in which it is the role ofthe EU Commission to contain systems competition in order to preserve "stability in diversity." The role ofthe EU level would be to promote horizontal and vertical learning processes and to make sure that stability concerns ofthe EU are taken seriously by member countries' governments. The minimum requirements framework for social policy that the EU Commission has adopted must be taken as a point of departure, even though it is a less than satisfactory approach from this point of view. Laboratory standardization, in contrast, would not set specific minimum requirements but meta-standards that protect systems functions and safeguard against systems failures.

Although androgens are commonly seen as male sex hormones, it has been established over the years that in both sexes, androgens also respond to social challenges. To explain the socially driven changes in androgens, two theoretical models have been proposed: the biosocial model and the challenge hypothesis. These models are typically seen as partly overlapping; however, they generate different predictions that are clarified here. In humans, sports competition and nonmetabolic competitive tasks have been used in the laboratory setting, as a proxy for agonistic interactions in animals. The results reviewed here show that the testosterone (T) response to competition in humans is highly variable – the studies present postcompetition T levels and changes in T that depend on the contest outcome and that cannot be predicted by the current theoretical models. These conflicting results bring to the foreground the importance of considering cognitive factors that could moderate the androgen response to competition. Among these variables, we elect cognitive appraisal and its components as a key candidate modulating factor. It is known that T also modulates the cognitive processes that are relevant to performance in competition. In this article, we reviewed the evidence arising from studies investigating the effect of administering exogenous T and compare those results with the findings from studies that measured endogenous T levels. Finally, we summarized the importance of also considering the interaction between androgens and other hormones, such as cortisol, when investigating the social modulation of T, as proposed by the dual-hormone hypothesis.

The previous chapter uncovered important differences between decision-making structures across the 11 processes investigated by this study. As we have noted, both historically and in much contemporary literature, the Swiss political system has been described as highly consensual. And yet, when we focus on differences between decision-making structures across different policy domains, important elements appear that point toward a more conflictual style of decision-making. Both when there is a power balance between coalitions and in the presence of a dominant coalition, coalition interactions are conflictual in the majority of cases. Based on the descriptive account of these differences in Chapter 4, the present chapter studies the conditions under which given decision-making structures emerge. Under which circumstances are actors able to form a dominant coalition, and which conditions lead to a situation where power is more evenly balanced between coalitions? Which conditions lead actors to develop a conflictual rather than a consensual type of interaction? Answering these questions can give us some indication of the factors responsible for different types of decision-making structures.
