Parental Self‐Efficacy for Reducing the Risk of Adolescent Depression and Anxiety: Scale Development and Validation

Burgeoning research suggests that parents can reduce the risk of anxiety and depression in their adolescents and that parental self‐efficacy (PSE) may be related to parental risk and protective factors for these disorders. As there are currently no measures available to assess PSE in relation to parenting behaviors that may reduce adolescent risk for depression and anxiety, we developed and validated a measure of PSE, the Parental Self‐Efficacy Scale (PSES). Using a sample of 359 parents and 332 adolescents (aged 12–15), the PSES was found to have high reliability, confirmatory factor analysis supported its validity, and most of the hypothesized relationships between the PSES and other measures of parenting practices and adolescent depressive and anxiety symptoms were supported.

On the genealogy and coalescence times of Bienaymé–Galton–Watson branching processes

Coalescence processes have received a lot of attention in the context of conditional branching processes with fixed population size and non-overlapping generations. Here, we focus on similar problems in the context of the standard unconditional Bienaymé–Galton–Watson branching processes, either (sub)-critical or supercritical. Using an analytical tool, we derive the structure of some counting aspects of the ancestral genealogy of such processes, including: the transition matrix of the ancestral count process and an integral representation of various coalescence times distributions, such as the time to most recent common ancestor of a random sample of arbitrary size, including full size. We illustrate our results on two important examples of branching mechanisms displaying either finite or infinite reproduction mean, their main interest being to offer a closed form expression for their probability generating functions at all times. Large time behaviors are investigated.

PARLIAMENT SHAPES AND SIZES

This paper proposes a model of Parliamentary institutions in which a society makes three decisions behind the veil of ignorance: whether a Parliament should comprise one or two chambers, what the relative bargaining power of each chamber should be if the Parliament is bicameral, and how many legislators should sit in each chamber. We document empirical regularities across countries that are consistent with the predictions of our model. (JEL D71, D72)     

Recursive Methods in Discounted Stochastic Games: An Algorithm for δ→ 1 and a Folk Theorem

We present an algorithm to compute the set of perfect public equilibrium payoffs as the discount factor tends to 1 for stochastic games with observable states and public (but not necessarily perfect) monitoring when the limiting set of (long‐run players') equilibrium payoffs is independent of the initial state. This is the case, for instance, if the Markov chain induced by any Markov strategy profile is irreducible. We then provide conditions under which a folk theorem obtains: if in each state the joint distribution over the public signal and next period's state satisfies some rank condition, every feasible payoff vector above the minmax payoff is sustained by a perfect public equilibrium with low discounting.     

Observer,consigner, tracer. Les usages d’un cahier électronique controversé en établissement pénitentiaire pour mineurs

This contribution, based on research conducted within a Prison for Minors, provides an analysis of the guards’ use of a software application: the “electronic observation logbook”, designed to record and disseminate various day-to-day “observations” about prisoners. The analysis of the use of this system — which simultaneously attempts to “profile” prisoners and “track” surveillance activity — not only helps conceptually identify the type of surveillance employed in a Prison for Minors, it also reveals the growing complexity of the work of prison guards, previously studied primarily in terms of the informality of the interactional frameworks in prison.     

The Social Impacts of Electronic Mail in Organizations: A case study of electronic power games using communication genres

This paper investigates the effects of the introduction of electronic mail on organizational structure and power. It provides empirical support to the view that technology, organizational context, and individual actors interact to shape the use of Information and Communication Technologies (ICTs) and their effect on organizations. Through an analysis of power games reflected in the progressive constitution of electronic mail genres, it illustrates in particular how the specific organizational configurations in which technology is deployed deeply influence its ultimate use. Far from transforming an organization, it appears that the introduction of electronic communication tools may in certain circumstances help reinforce an organization's preexisting structure.
