The Impact

This study examines the impact of appearance in juvenile court on perceptions of self, associations with peers who use marijuana, beliefs that the law is morally binding on oneself, and fear of legal sanctions for the use of marijuana, and subsequent self-reported marijuana use. A basic model specifying relationships among these variables is derived from both labeling theory and the deterrence approach. Findings from panel data collected at, two points in time from high school students (n=378), and data from juvenile court records provide not support for the hypothesis of specific deterrence and only marginal support for labeling theory. Additional findings point to the group nature of marijuana use and indicate that with the group context the potential impact of appearance in juvenile court is largely negated. Finally, no support is found for the hypothesis that the fear of legal sanctions is an effective deterrent to use. Policy implications of the findings are discussed.

Negative Feelings

This article draws on data gathered in focus groups to analyze how people talk about homelessness and compares the findings to how homelessness is represented in the media, specifically newspapers. It examines how ideas about homelessness that circulate in society are taken up, used, and reproduced by people in social interaction. People “care” about homelessness and use emotion discourse in the focus group context to construct a moral identity and to manage interactional dilemmas. They express sympathy for homeless people, deflect responsibility for any negative feelings they may have, and shift responsibility for doing something about homelessness. In using emotion discourse, they reproduce conceptions of homelessness that circulate widely in the media and in society generally; this, in turn, reproduces existing social relations of inequality and exclusion.Cet article a recours à des données provenant de groupes de discussion afin d’analyser comment les gens parlent d’itinérance entre eux, puis il compare les résultats de cette analyse à la représentation de l’itinérance dans les médias contemporains, particulièrement les journaux. Il examine comment les gens dans leurs interactions adoptent, utilisent et reproduisent des idées sur l’itinérance qui circulent déjà dans la société. Les gens se « soucient » de l’itinérance et ont recours à un discours émotif dans leurs groupes de discussion pour se construire une identité morale et gérer les dilemmes interactionnels. Ils expriment de la sympathie pour les sans-abris, tout en déclinant toute responsabilité pour les sentiments négatifs que ces derniers peuvent éprouver et rejetant sur autrui le devoir d’agir sur l’itinérance. En utilisant un discours émotif, ils reproduisent des conceptions sur l’itinérance qui circulent abondamment dans les médias et dans la société en général. Leurs pratiques reproduisent ainsi des rapports d’inégalité et d’exclusion.

And Task

Task allocation among social insect workers is an ideal framework for studying the molecular mechanisms underlying behavioural plasticity because workers of similar genotype adopt different behavioural phenotypes. Elegant laboratory studies have pioneered this effort, but field studies involving the genetic regulation of task allocation are rare. Here, we investigate the expression of the foraging gene in harvester ant workers from five age- and task-related groups in a natural population, and we experimentally test how exposure to light affects foraging expression in brood workers and foragers. Results from our field study show that the regulation of the foraging gene in harvester ants occurs at two time scales: levels of foraging mRNA are associated with ontogenetic changes over weeks in worker age, location and task, and there are significant daily oscillations in foraging expression in foragers. The temporal dissection of foraging expression reveals that gene expression changes in foragers occur across a scale of hours and the level of expression is predicted by activity rhythms: foragers have high levels of foraging mRNA during daylight hours when they are most active outside the nests. In the experimental study, we find complex interactions in foraging expression between task behaviour and light exposure. Oscillations occur in foragers following experimental exposure to 13 L : 11 D (LD) conditions, but not in brood workers under similar conditions. No significant differences were seen in foraging expression over time in either task in 24 h dark (DD) conditions. Interestingly, the expression of foraging in both undisturbed field and experimentally treated foragers is also significantly correlated with the expression of the circadian clock gene, cycle . Our results provide evidence that the regulation of this gene is context-dependent and associated with both ontogenetic and daily behavioural plasticity in field colonies of harvester ants. Our results underscore the importance of assaying temporal patterns in behavioural gene expression and suggest that gene regulation is an integral mechanism associated with behavioural plasticity in harvester ants.
