‘The whole is always smaller than its parts’ – a digital test of Gabriel Tardes' monads

In this paper we argue that the new availability of digital data sets allows one to revisit Gabriel Tarde's (1843–1904) social theory that entirely dispensed with using notions such as individual or society. Our argument is that when it was impossible, cumbersome or simply slow to assemble and to navigate through the masses of information on particular items, it made sense to treat data about social connections by defining two levels: one for the element, the other for the aggregates. But once we have the experience of following individuals through their connections (which is often the case with profiles) it might be more rewarding to begin navigating datasets without making the distinction between the level of individual component and that of aggregated structure. It becomes possible to give some credibility to Tarde's strange notion of ‘monads’. We claim that it is just this sort of navigational practice that is now made possible by digitally available databases and that such a practice could modify social theory if we could visualize this new type of exploration in a coherent way.     

Interpretations of Child Emotion Expressions and Coercive Parenting Practices Among Adolescent Mothers

This study examined the relation between adolescent mothers' interpretations of various child emotion expressions and coercive parenting practices (n = 4 mother-child dyads, child ages = 10–34 mos.). The more coercive mothers decoded a range of child emotion expressions as exhibiting greater anger, and attributed greater defiant intentions to the child, compared to less coercive mothers. The findings for attributions of defiance were robust, as they were independent of both emotion decoding and level of child difficulty. Findings are discussed with regard to (a) mothers' basic assumptions about the child; (b) the robust character of attributions of defiance in relation to coercive parenting; (c) the potential implications of this study for research with adult mothers; and (d) investigation of temporal precedence and developmental pathways in the interrelations among child behavior, maternal cognition, and parenting behavior.

Potential and probable pathological gamblers: Where do the differences lie?

A large proportion of adolescents engage in gambling activities and the prevalence of pathological gambling is high. This study presents a factor analysis of responses from 122 college students who obtained a score of 3 or greater on the South Oaks Gambling Screen (SOGS), the most widely used instrument to identify probable and potential pathological gamblers. The analysis showed five dimensions: Illegal Behaviors, Heavy Gambling, Eating Disorders, Parentally Modelled/Less Impulsive, and Worry. Analyses revealed that except for the Eating Disorders factor, all factors clearly differentiated the probable from potential pathological gamblers, as identified by the SOGS. Results raise important questions about the relationship of pathological gambling to other psychopathological or antisocial behaviors. Thus the probable pathological gambler category represents a wide-ranging behavioral profile that goes beyond gambling per se. Avenues for future research as well as clinical implications are discussed.This research was partially supported by grants from Le Fonds Richelieu, le Conseil Québécois de la Recherche Sociale and the Social Sciences and Humanities Research Council of Canada.     

The Endowment Effect,Status Quo Bias and Loss Aversion: Rational Alternative Explanation

The endowment effect, status quo bias, and loss aversion are robust and well documented results from experimental psychology. They introduce a wedge between the prices at which one is willing to sell or buy a good. The objective of this paper is to address this wedge. We show that the presence of asymmetric information in a rational-agent framework can also account for the endowment effect, status quo bias and loss aversion without invoking psychology-based explanations proposed in the past.     

Some Further Results on the Manipulability of Social Choice Rules

A typology of electoral environments in which strategic manipulation of voting rules can occur is proposed. From this typology, six different concepts of equilibria (or quasi-equilibria) are defined, including the usual ones. Then, focusing on three alternative elections, we derive some analytical representations for the vulnerability of a large number of voting rules to strategic manipulation by considering successively each type of equilibrium. Our results show that the hierarchy of the rules changes when the voting framework is modified. However, some rules are clearly dominated and some others (among which the Borda and the Nanson rules) appear to be uniquely the best in some specific contexts.
