Can a perceptual peer deviance measure accurately measure a peer's self-reported deviance?

Purpose

Social learning theory and self-control theory differ considerably in their interpretation of what qualifies as a “valid” measure of peer deviance. While the two theories are epistemological opposites in regards to how to operationalize the peer deviance construct, their differences are reconcilable. The current study seeks to identify a set of perceptual items that accurately measure a peer's self-reported deviance. This measure would satisfy the preferences of both learning and control theories because the measure is perceptual but also accurate.

Methods

Using data from 2,154 individuals in friendship pairs where each respondent perceived 26 peer behaviors and self-reported the same behaviors, regression, item-response, and mean difference tests are used to perform item deletion.

Results

Five perceptual peer deviance items are identified which are not significantly different from the peer's self-reported deviance. When scaled together and inserted into multivariate regressions, however, the perceptual peer deviance items are still related to the respondent's deviance more strongly than the peer's self-reported deviance.

Conclusions

We are unable to identify a set of perceptual items that is interchangeable with a peer's self-reported deviance. Accordingly, the theoretical debate between Akers and Gottfredson and Hirschi regarding the measurement of differential association may not be empirically resolvable.     

Healthy, wealthy, and wise: Incorporating health issues as a source of strain in Agnew's general strain theory

The current study uses Agnew's general strain theory (GST) as a foundation to argue that poor health may lead to delinquency. Those who suffer frequently from minor health problems and lack resources to afford proper medical care are expected to experience elevated levels of health-related strain, negative emotional affect, and report engaging in more delinquent acts. Using longitudinal data from the National Longitudinal Study of Adolescent Health (Add Health), negative binomial regression models were estimated and show that health strains increase the subsequent frequency of non-violent delinquency even when controlling for important demographic and theoretically derived variables. Health strain's influence on non-violent delinquency was not conditioned by anger, depression, self-esteem, low constraint, or religiosity. Implications for GST are discussed and a modest research agenda for investigating health strain is identified.     

Community violence and PTSD in selected South African townships

Given the high rates of crime in South Africa's townships, nonpolitical violence out-side the home and its psychological impact on women were investigated within two samples, the primary a help-seeking sample and the secondary a community sample. In the help-seeking sample, two thirds of the women reported having experienced several traumatic events outside the home. Those women displayed a median of 9 PTSD (post-traumatic stress disorder) symptoms, with nearly half meeting all criteria for PTSD. In the community sample, 40 women of color were interviewed at a community festival for women, and again two thirds reported having experienced several traumatic events outside the home during the previous year. These women displayed a median of 8.8 PTSD symptoms, with none meeting all criteria for PTSD. South Africa's distinctive culture of violence is discussed as context for understanding issues of community violence and PTSD among women in its minority townships.     

Maternal cigarette smoking during pregnancy and life-course-persistent offending

Evidence exists documenting the relationship between maternal cigarette smoking and offspring criminal behavior. Although efforts to understand this relationship in a theoretical framework have only recently emerged, attempts made have been grounded in Moffitt's developmental taxonomy of antisocial behavior. Specifically, maternal cigarette smoking is generally viewed as a potential disruption in the offspring's neuropsychological development, which is subsequently associated with life-course-persistent offending. Using a birth cohort of 987 African Americans, the authors extend previous research by empirically assessing, prospectively, the link between maternal cigarette smoking and life-course-persistent offending while using different operationalizations of Moffitt's offending categorization. The authors' findings offer some support for the relationship between maternal cigarette smoking and life-course-persistent offending, which is dependent on how this concept is operationalized.     

A shot in the arm for the military: consent to immunisation against biological warfare agents

The risk to Britain's Armed Forces from Biological Warfare (BW) is low but without protection their use would be devastating. Available protective measures include immunisation. The Government owes a legal duty of care to Servicemen to provide protection against a range of hazards, including those of BW. The State also owes Servicemen a duty of care to allow free and informed consent or free and informed refusal to medical procedures, including immunisation. However, refusal by key personnel to accept BW immunisation could degrade operational capability. Resolution between these two, potentially conflicting, duties of care may be controversial. To override a soldier's expressed interests would rank society's needs higher than those of the individual. Yet there are circumstances, such as exposure of Servicemen to BW used by an aggressor, where this would be ethically acceptable. The State's interests, combined with the best interests of the Servicemen, provide adequate ethical argument for both occupational immunisation (where it is an entry criterion for the Armed Forces) and mandatory immunisation (where disciplinary action may be taken against the non-compliant). Historically, both approaches have been used for public health immunisations and the legal framework already exists for both.     

Has Legislative Television Changed Legislator Behavior?: C-SPAN2 and the Frequency of Senate Filibustering

Using data from 1959–1998, this studyexamines the impact of legislativetelevision (C-SPAN2) on the number offilibusters in the United States Senate. As previous work has suggested, theinstitutional rules of the federallegislative branch of government in theU.S. often allow for politicalgrandstanding and posturing, and theseactivities are enhanced with the presenceof television cameras on the legislativefloor. Like those previous studies, thepresent work builds a theoretical modelwherein political services are consideredsearch/experience goods, and serviceproviders (federal legislators) areexpected utility maximizers who areconcerned with promoting their policypreferences and their re-electionprospects. Poisson model estimates suggestthat the presence of legislative televisionhas worked to increase the filibuster countin the Senate. As a result, such posturingand positioning on the issues by incumbents(in front of television cameras) is costlyfor challengers to replicate and likelycontributes to lower turnover rates in thelegislative branch.
