Evidence of incomplete cortical modulation of autonomic responses in 11-to 16-year-old adolescents

This study examines response differentiation in the sympathetically innervated skin conductance response (SCR). Differentiation in such systems has been ascribed to cortical inhibitory control over subcortical autonomic centers. Developmental study of such differentiation thus provides information on cortical development and the maturation of cortical control over subcortical centers. Previous investigators have focused on the simple level of differentiation involved in discriminating response on one side the body from that on the other. In such studies several investigators reported more diffuse response among young children; some reported adultlike differentiation by approximately age 10. The present study examines a more complex instance of differentiation, the quantitative modulation of response from a given site in order to produce SCR amplitudes proportionate to the information value of the eliciting stimulus. Relatively large amplitude SCRs elicited by imperative PRESS-SIGNALS of varying information value were studied, together with smaller SCRs elicited by NONPRESS-SIGNALS also varying in information value, in two adolescent groups, aged 11–16 years, and in a young adult sample. In contrast to earlier work, the present study demonstrates a continuing difference between adolescents and adults. Adults showed consistent differentiation, with SCR amplitude reflecting changes in stimulus information values for both PRESS- and NONPRESS-SIGNALS. Adolescents displayed differentiation only for SCRs elicited by NONPRESS-SIGNALS: Response to PRESS-SIGNALS did not reflect stimulus information values, even though reaction time data demonstrated that PRESS-SIGNAL information was being registered cortically. The degree of cortical control present in these adolescents, enabling them to display differentiated SCRs to NONPRESS-SIGNALS, would likely be sufficient to allow simple left-right discrimination, perhaps accounting for the adultlike reactions previously reported for this age group. The inability of the adolescents to sustain SCR differentiation when large amplitude responses were elicited by the PRESS-SIGNALS might reflect the inability of still immature cortical controls to cope with sizable sympathetic output. A critical level of sympathetic arousal may exist for adolescents in this age range, above which cortical inhibitory controls may become ineffective.This study was supported in part by NIMH Research Grant 15633 to the first author.Received his Ph.D in psychology from the University of Buffalo.

The politics of decarbonization and the catalytic impact of subnational climate experiments

The Paris Agreement of 2015 marks a formal shift in global climate change governance from an international legal regime that distributes state commitments to solve a collective action problem to a catalytic mechanism to promote and facilitate transformative pathways to decarbonization. It does so through a system of nationally determined contributions, monitoring and ratcheting up of commitments, and recognition that the practice of climate governance already involved an array of actors and institutions at multiple scales. In this article, we develop a framework that focuses on the politics of decarbonization to explore policy pathways and mechanisms that can disrupt carbon lock-in through these diverse, decentralized responses. It identifies political mechanisms—normalization, capacity building, and coalition building—that contribute to the scaling and entrenchment of discrete decarbonization initiatives within or across jurisdictions, markets, and practices. The role for subnational (municipal, state/provincial) climate governance experiments in this new context is especially profound. Drawing on such cases, we illustrate the framework, demonstrate its utility, and show how its political analysis can provide insight into the relationship between climate governance experiments and the formal global response as well as the broader challenge of decarbonization.     

Youth alcohol use and dating abuse victimization and perpetration: a test of the relationships at the daily level in a sample of pediatric emergency department patients who use alcohol

Objective: This study retrospectively examined the daily-level associations between youth alcohol use and dating abuse (DA) victimization and perpetration for a 6-month period. Method: Timeline Followback (TLFB) interview data were collected from 397 urban emergency department patients, ages 17 to 21 years. Patients were eligible if they reported past month alcohol use and past year dating. Generalized estimating equation (GEE) analyses estimated the likelihood of DA on a given day as a function of alcohol use or heavy use (≥4 drinks per day for women, ≥5 drinks per day for men), as compared with nonuse. Results: Approximately 52% of men and 61% of women participants reported experiencing DA victimization ≥1 times during the past 6 months, and 45% of men and 55% of women reported perpetrating DA ≥1 times. For both men and women, DA perpetration was more likely on a drinking day as opposed to a nondrinking day (ORs = 1.70 and ORs = 1.69, respectively). DA victimization was also more likely on a drinking day as opposed to a nondrinking day for both men and women (ORs = 1.23 and ORs = 1.34, respectively). DA perpetration and DA victimization were both more likely on heavy drinking days as opposed to nondrinking days (2.04 and 2.03 for men's and women's perpetration, respectively, and 1.41 and 1.43 for men's and women's victimization, respectively). Conclusions: This study found that alcohol use was associated with increased risk for same day DA perpetration and victimization, for both male and female youth. We conclude that for youth who use alcohol, alcohol use is a potential risk factor for DA victimization and perpetration.     

What did Apalachin prove? Mafia skepticism in cold war politics and culture

With varying degrees of enthusiasm, federal, state, and local governments had been investigating and prosecuting gangsters since the late nineteenth century. Despite this relatively long history, the primary interpretation of the Apalachin arrests lay in the belief that the New York State Police had uncovered proof of the existence of organized crime. This essay investigates the reasons why there seemed to be an ongoing need to prove its existence, concluding that organized crime came to be defined within the cultural and political agendas of Cold War America. Drawing on media accounts, government documents, archival sources, and popular non-fiction, this essay argues that rather than the conclusive proof of the mafia, Apalachin is best viewed as an exhibit in an ongoing argument about the existence and meaning of organized crime.
