Editorial

This special issue addresses the analytical problem of agency in earth system governance, an analytical problem that begins with the assumption that the credibility, stability, adaptiveness, and inclusiveness of earth system governance is affected by a wide range of actors, including national governments and their bureaucracies as well as the growing population of non-state actors such as environmental organizations, expert networks, and corporations. The articles included in this special issue engage with questions of agency in earth system governance from several different theoretical perspectives, complemented by unique empirical cases and/or methodological approaches. Along the way, the authors confront some of the conceptual challenges associated with the study of agency and advance our understanding of this important governance challenge.     

Nanotechnology for forensic sciences: Analysis of PDMS replica of the case head of spent cartridges by optical microscopy, SEM and AFM for the ballistic identification of individual characteristic features of firearms

A novel application of replica molding to a forensic problem, viz. the accurate reproduction of the case head of gun and rifle cartridges, prior and after been shot, is presented. The fabrication of an arbitrary number of identical copies of the region hit by the firing pin and by the breech face is described. The replicas can be (i) handled without damaging the original evidence, (ii) distributed to different law enforcement agencies for comparison against other evidences found on crime scenes or ballistic tests of seized firearms, (iii) maintained on a file by the laboratories. A detailed analysis of the morphological features of the replicas has been carried out by standard microscopy techniques as well as by advanced microscopy such as scanning probe and scanning electron leading to a quantitative morphological characterization of the case heads down to the nanometer scale. The assignment of the cartridge replicas to the shooting weapon is demonstrated to hold below the micron scale, while it is hindered at the nanometer level both by the manufacturing differences and by eventual modifications occurring on the firing pin.     

Psychiatric correlates of medical care costs among veterans receiving mental health care

Research on increased medical care costs associated with posttraumatic sequelae has focused on posttraumatic stress disorder (PTSD). However, the provisional diagnosis of Disorders of Extreme Stress Not Otherwise Specified (DESNOS) encompasses broader trauma-related difficulties and may be uniquely related to medical costs. We investigated whether DESNOS severity was associated with greater nonmental health medical care costs in veterans receiving mental health care. Participants were 106 men and 105 women receiving VA outpatient mental health treatment. A standardized interview assessed DESNOS severity. The dependent variables consisted of primary and specialty medical treatment costs. Sequential zero-inflated negative binomial regression was used to evaluate the variance in medical costs accounted for by DESNOS severity, controlling for PTSD severity and established predisposing, enabling, and need-based health care factors. Contrary to our hypothesis, in fully adjusted models, DESNOS severity independently added a significant amount of variance to lower specialty medical care costs, whereas PTSD did not consistently account for significant variance in medical care costs. Greater DESNOS severity appears to be associated with lower specialty medical care costs but not primary care costs. These findings may indicate that patients with DESNOS symptoms are at risk for being underreferred for specialty care.     

Offender Presence, Available Victims, Social Disorganization and Sex Offense Rates

The present study examines the utility of social disorganization theory for identifying community characteristics associated with varying rates of sex offenses both in general and against children. Measures of economic deprivation, community stability, cohesion, informal social control, presence of known offenders, and available opportunities are used in one urban county (Louisville, KY) to identify characteristics of census tracts with high rates of sex offenses. Results show that social disorganization theory is a moderately useful explanation for sexual offenses against adults, but not for sexual offenses against children.     

Age of First Arrest,Sex, and Drug Use as Correlates of Adult Risk Behaviors Among Rural Women in Jails

Incarcerated women frequently report initiation of substance use and sexual encounters at an early age, and often engage in high-risk drug use and sexual behaviors as adults. This study examined the timing of first sex, drug use, and arrest, as well as their unique influences on specific risky behaviors in adulthood, among a high-risk population of rural women recruited from jails. Ages of initiation were all positively and significantly correlated, and each independently increased the likelihood of several risky behaviors in adulthood. Implications are discussed for screening, intervention, and treatment targeting high-risk women and girls in rural areas, particularly within criminal justice settings.     

Stalking by law: damaging victims and rewarding offenders

The introduction of anti-stalking statutes throughout Australia and much of the Western world has brought greater protection for the victims of various forms of harassment and intrusions. However, despite these new provisions, the legal system is failing some victims of stalking. This article examines those areas of the justice system that are particularly susceptible to manipulation by stalkers and the impact of these abuses on stalking victims. It also presents ways in which the problems encountered by stalking victims may be frustrated rather than alleviated by specific aspects of the enforcement of anti-stalking laws and of the functioning of certain courts and tribunals. Approaches that prevent or discourage the perpetuation of harassment and damage to victims of stalking within the legal system are discussed.     

Perceived vs. actual friends' use of alcohol,cigarettes, marijuana,and cocaine: Which has the most influence?

Determinants of the use of alcohol, alcohol without parental knowledge, cigarettes, marijuana, and crack were assessed in predominantly black, urban, fourth- and fifth-grade students. Each subject identified three best friends. Logistic and least-square regression analyses indicated that children's perceptions of friends' use, perceptions of family use, and actual use of classmates were better predictors of substance use than friends' actual use. The pattern of predictors suggested that peer behaviors and attitudes are more influential for children's socially censured behaviors such as using alcohol without parental permission than for more socially approved behaviors such as using alcohol with parental permission. The importance of perceived friends' use vs. friends' actual use supports Behavioral Intention Theory and Cognitive Developmental Theory, while the importance of classroom use supports Social Learning Theory or may reflect social and environmental conditions including neighborhood availability of drugs and neighborhood values regarding substance use.This research was supported by a grant from the National Institute on Drug Abuse (RO1 DA 04497).
