This study explored associations between group memberships and recovery capital amongst 20 young adults aged 18 to 21 years in residential alcohol and drug treatment. Method Participants completed an interviewer administered research interview based on measures of recovery capital and a social networks assessment mapping group memberships, group substance use, and relationships between groups...

A crucial problem in the design of multi-issue group decisions is the definition of rules that select outputs that are consistent with existing correlations between multiple issues. A less known problem arises when the collective outcome is supported by none or by the fewest individuals, bringing into question the compatibility of a collective decision with respect to individual choices. The ai...

The present article introduces a model based on cognitive consistency principles to predict how new identities become integrated into the self-concept, with consequences for intergroup attitudes. The model specifies four concepts (self-concept, stereotypes, identification, and group compatibility) as associative connections. The model builds on two cognitive principles, balance–congruity and im...

We analyse firms’ incentives to provide two-way compatibility between two network goods with different intrinsic qualities. We study how the relative importance of vertical differentiation with respect to the network effect influences the price competition as well as the compatibility choice. The final degree of compatibility allows firms to manipulate the overall differentiation. Under weak ne...

Therefore, practitioners have adapted standard tools in a simple way: first, convert the heterogeneous distribution of income and non-income characteristics into an equivalent distribution of living standards and second, apply the preferred standard tool to the distribution of living standards, either unweighted, or weighted by the number of individuals. The essence of the living standard funct...

New institutionalism is an approach to the study of social events that is becoming increasingly popular. Different lines of new institutional research can be distinguished. In one line of research it is argued that the social sciences should transcend reductionist modes of explanation, in particular the methodological individualism exemplified by the theory of rational choice. In this view, red...

Many cases of externalities in agricultural production, such as pesticide drift, crosspollination, and offensive odors, are attributable to the incompatibility of neighboring land uses and exhibit distance dependence. We characterize equilibrium spatial patterns of externality-generating and -receiving land uses on a two-dimensional lattice with noncooperative, profit-maximizing producers. In e...

Motor actions are facilitated if they are foreseeably being imitated rather than counterimitated by social partners. Such beneficial effects of anticipated imitation have been explained in terms of compatibility between one's own actions and their anticipated consequences. Previous demonstrations of these effects might alternatively be explained by consistently faster partner responses for imit...

In an infinite-horizon setting, Ferejohn and Page showed that Arrow’s axioms and stationarity lead to a dictatorship by the first generation. Packel strengthened this result by proving that no collective choice rule generating complete social preferences can satisfy unlimited domain, weak Pareto and stationarity. We prove that a domain restriction can be imposed and completeness can be dropped ...

Whether developed by a firm (de-facto) or set by a committee (de-jure), interface standards are an important element of competition in software industries. While adopting the right set of technology standards for their products is crucial for firms in the enterprise software industry, the absence of a single set of open standards or leading standards from a dominant firm makes this choice diffi...
