The matching law in and within groups of rats

In each of the two experiments, a group of five rats lived in a complex maze containing four small single-lever operant chambers. In two of these chambers, food was available on variable-interval schedules of reinforcement. In Experiment I, nine combinations of variable intervals were used, and the aggregate lever-pressing rates (by the five rats together) were studied. The log ratio of the rates in the two chambers was linearly related to the log ratio of the reinforcement rates in them; this is an instance of Herrnstein's matching law, as generalized by Baum. Summing over the two food chambers, food consumption decreased, and response output increased, as the time required to earn each pellet increased. In Experiment II, the behavior of individual rats was observed by time-sampling on selected days, while different variable-interval schedules were arranged in the two chambers where food was available. Individual lever-pressing rates for the rats were obtained, and their median bore the same “matching” relationship to the reinforcement rates as the group aggregate in Experiment I. There were differences between the rats in their distribution of time and responses between the two food chambers; these differences were correlated with differences in the proportions of reinforcements the rats obtained from each chamber.     

EMPIRICALLY DERIVED INJURY PREVENTION RULES

This study describes a set of empirically derived safety rules that if followed, would have prevented the occurrence of minor injuries. Epidemiologists have criticized behavioral interventions as increasing “safe” behavior but failing to demonstrate a decrease in injury. The present study documents retrospectively the link between safe behavior and injury. It demonstrates that these empirically derived rules are very similar to rules for the prevention of serious injury. The study also shows that these rules are not widely accepted and implemented by parents. Suggestions for future research in this area are advanced.     

Biased lineups: sequential presentation reduces the problem.

Biased lineups have been shown to increase significantly false, but not correct, identification rates (Lindsay, Wallbridge, & Drennan, 1987; Lindsay & Wells, 1980; Malpass & Devine, 1981). Lindsay and Wells (1985) found that sequential lineup presentation reduced false identification rates, presumably by reducing reliance on relative judgment processes. Five staged-crime experiments were conducted to examine the effect of lineup biases and sequential presentation on eyewitness recognition accuracy. Sequential lineup presentation significantly reduced false identification rates from fair lineups as well as from lineups biased with regard to foil similarity, instructions, or witness attire, and from lineups biased in all of these ways. The results support recommendations that police present lineups sequentially.     

Identity Development in Adulthood: A Longitudinal Study

Identity status interviews involving five domains of life (religious beliefs, political ideology, occupational career, intimate relationships, and lifestyle) were conducted with 249 women and men at ages 27 and 36. The results on overall identity and domain-specific identities confirmed our general hypothesis as to the strengthening of the commitment process: (1) stability was higher in the identity statuses involving commitment (identity achievement and foreclosure) than in the statuses not involving commitment (identity diffusion and moratorium); (2) an increase in the salience of identity domains could be attributed to an increase in the commitment process; (3) transitions into identity statuses involving commitment were more frequent than transitions into statuses not involving commitment; indicating that both identity achievement and foreclosure might be end points of identity development. It was concluded that the results pointed to identity development in adulthood rather than to a random fluctuation in identity statuses over time.     

Elevated prolactin levels among adult male sex offenders

A sample of 528 successive admissions to the Phoenix Program, a voluntary inpatient treatment program for sex offenders, was studied in regards to serum prolactin levels. Serum prolactins were obtained as part of a battery of endocrine tests. A substantial number of patients had prolactin levels above the normal range, i.e., 21.0 microg/L. In this sample, fully 10.0% of the men showed elevated prolactin levels (the maximum being 41.0 microg/L), compared with an expected 2.5% according to laboratory norms. None of these individuals had clinical manifestations of prolactinoma. The significance of this increased rate of hyperprolactinemia in this sample of sexual offenders is unclear. There was a negative correlation with age and no correlation with other endocrine tests.     

A Permissive Theory of Territorial Rights

This article explores the justification of states' territorial rights. It starts by introducing three questions that all current theories of territorial rights attempt to answer: how to justify the right to settle, the right to exclude, and the right to settle and exclude with reference to a particular territory. It proposes a ‘permissive’ theory of territorial rights, arguing that the citizens of each state are entitled to the particular territory they collectively occupy, if and only if they are also politically committed to the establishment of a global political authority realizing just reciprocal relations. The article is developed by introducing some key features of the permissive theory and by explaining how such an account addresses the questions of settlement, exclusion and particularity in ways that significantly improve on existing rival accounts (most prominently: acquisition theories, legitimacy‐based theories and nationalist theories).     

“Hit Me Baby”: From Britney Spears to the Socialization of Sexual Objectification of Girls in a Middle School Drama Program

This language socialization study integrates ethnographic and intertextual methods of data collection and analysis to examine how one middle school drama class’s performance of Britney Spears’s first hit song, originally titled “Hit Me Baby One More Time,” exemplifies not only how sexually charged media can contribute to the normalization of sexist, abusive, and thus also violent behavior toward women, but also how local caretaking adults can contribute to these socialization practices even within the context of official educational activities. Prior studies related to the socialization of gender equality and sexual abuse prevention in educational institutions have focused on whether and how adult intervention may prevent or stop gender and thus also sexually related abuse. This study indicates that further research into adult complicity and the need for intervention into adult behavior may also be called for. The ethnographic fieldwork for this paper was conducted during a larger language socialization study at a middle school in the western United States. This included the videotaping of rehearsals and performances by middle school students of popular songs. The intertextual data chosen for analysis is based on these ethnographic observations. The conclusion that some adults are actively socializing female sexual objectification and male dominance during school-based activities is based on observations of these locally occurring interactions.     

SCHOLARS,AMATEURS, AND ARTISTS AS PARTNERS FOR THE FUTURE OF RELIGION AND SCIENCE

We recommend that the future of religion and science involve more partnerships between scholars, amateurs, and artists. This reimagines an underdeveloped aspect of the history of religion and science. Case studies of an undergraduate course examining religious ritual and technology, seminarians reflecting on memory and identity in light of Alzheimer's disease, environmentalists responding to their guilt and shame about climate change, and Chicagoans recognizing the presence of nature in the city show how these partnerships respect insights and experiences of our varied partners, identify and resolve community problems, and advance scholarship. Sourdough starter, a new metaphor, describes these collaborative, nourishing partnerships.
