A Sensitivity Analysis of Egocentric Measures of Peer Delinquency to Latent Homophily: A Research Note

Objectives

Egocentric measures of peer delinquency, obtained through a census of a social network, have become the preferred operationalization for examining the relationships between social influence and delinquency. Studies regressing ego’s delinquency on the delinquency of nominated friend/s (i.e. alter/s) conclude that a statistically significant coefficient provides evidence of social influence. However, the inferences drawn from these studies may be biased by the introduction of artificial statistical dependence as a consequence of using social network data in a regression framework. Recent work (Shalizi and Thomas Sociol Methods Res 40:211–239, 2011) shows that latent homophily, or unmeasured confounding of observables, may lead to nonzero estimates of social influence, even if there is no causal significance. To examine this possibility, sensitivity analyses have been created (e.g. VanderWeele and Arah Epidemiology 22:42–52, 2011; VanderWeele Sociol Methods Res 40:240–255, 2011) to determine the robustness of an estimated coefficient to latent homophily.

Methods

In this research note, I examine the robustness of estimates for social influence from two articles (Haynie Am J Sociol 106:1013–1057, 2001; Meldrum et al. J Res Crime Delinq 46:353–376, 2009) using egocentric measures of peer delinquency.

Results

Findings indicate that for large, precise point estimates, highly improbable conditions are needed to explain away the effects of social influence. However, less precise point estimates (i.e. large standard errors) are more sensitive to latent homophily.

Conclusions

The analyses indicate that studies using egocentric measures should conduct sensitivity tests, particularly when the estimated effect is weak and/or has a relatively large standard error. Scripts written in the free programming language R (R Core Team R: a language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, 2012) are provided for researchers to conduct such analyses.     

Typologies in Comparative Criminal Justice Research

This article focuses on typology construction as a focal technique in the analysis of crime and crime control systems from a world perspective. The relationship between theories and typologies is discussed. The author stresses the structure of theory when the world is defined as a system which includes sub-systems. Theoretical schemes depend on the existence of world sub-system typologies. Crime typologies and legal system typologies are needed because the formulation of a world law will be affected by the existence of typologies which clarify the similarities and dissimilarities of world legal systems.     

犯罪后的第三种法律后果:保护处分

保护处分即少年犯罪处遇中具有替代(并非补充)刑罚性质的措施,它具有超越刑罚亦超越保安处分的鲜明特点,有犯罪之后的“第三种法律后果”之称。保护处分应当遵循三大基本原则,即处分法定原则、处分优先原则和处分相称原则。保护处分包括机构性保护处分和非机构性保护处分两大基本类型。各国(地区)对于保护处分的类型设计及其运用无不以社区性保护处分为原则,而以拘禁性保护处分为例外。保护处分是现代少年刑法的核心内容,仍然停留于报应主义阶段的我国少年刑法急需加快改革,建立保护处分制度。     

Friendship Networks and Delinquency: The Relative Nature of Peer Delinquency

Although acknowledging the importance of adolescent friendships in the etiology of delinquency, prior studies have yet to provide a detailed examination of the role of actual friendship networks in delinquency. Using data from the National Longitudinal Study of Adolescent Health (1995–1996), this study's incorporation of friendship networks allows for a more rigorous conceptualization and measurement of peer delinquency based on carefully defined networks of adolescent friendships. Findings illustrate that friendship networks are very heterogenous in terms of members' participation in delinquent behavior with the majority of adolescents belonging to networks containing both delinquent and non-delinquent friends. In support of differential association's premise that delinquent behavior is influenced by the ratio of definitions favorable to those unfavorable to law violation (Sutherland, 1947), the proportion of delinquent friends in a respondent's network is most strongly associated with respondents' subsequent delinquency. This relative measure of peer delinquency is preferable to a measure of the absolute level of delinquency occurring by friends, the average delinquency committed by friends, or the absolute number of delinquent friends. Enmeshment in a friendship network where consensus about the appropriateness of delinquency is maximized (i.e., all friends are delinquent or non-delinquent) most effectively constrains the behaviors of network members to resemble the groups' behavior.     

Correctional Treatment Programmes for Young Offenders in Europe: A Survey of Routine Practice

This article presents the results of an international survey of European correctional treatment programmes for young offenders. Questionnaires gathering data on programmes’ design, implementation, structure, and evaluation were collected from 112 programme administrators in 25 European Union countries. Results demonstrated that although there was a commitment to young offender rehabilitation in almost every country, programmes adopted many different approaches and were implemented with varying levels of adherence to evidence-based principles of ‘best practice.’ The majority of programmes adopted a cognitive-behavioural approach, and clinical discretion was prioritised over systematised, empirically validated assessment instruments. Most programmes were administered by centralised government agencies; however, process and outcome evaluation was rare. These findings suggest a strong need for improved systematic evaluation in most European countries.     

Recommendations for Correctional Leaders to Reduce Boundary Violations: Female Correctional Employees and Male Inmates

The correctional profession continues to report boundary-violating behavior by correctional employees with inmates, such as aiding an inmate in an escape and engaging in sexual contact with an inmate. These criminal behaviors obviously threaten the safety within the institutions and the community; however, these types of actions are normally preceded by minor boundary crossings within the institution. Therefore, all types of boundary violations and crossings between an inmate and an employee must be examined and eliminated. This article offers correctional leaders recommendations for organizational change that may reduce the number of boundary violations and crossings between female employees and male inmates. These recommendations are built on a larger qualitative study that used portraiture methodology, by interviewing 4 former female correctional employees who developed relationships with male inmates.     

Correctional Officers and Domestic Violence: Experiences and Attitudes

This article presents the first statewide data regarding correctional officers’ attitudes about and personal experiences with domestic violence. Online surveys were administered to Florida correctional officers asking a series of questions, including their beliefs and attitudes about the prevalence of domestic violence among colleagues, and their childhood and adult experiences with domestic violence. Results from 710 officers revealed that 33?% of respondents knew about correctional officers who had committed unreported domestic violence; 30?% reported that they had directly experienced domestic violence as children; and over 11?% reported that they had been physically violent with an intimate partner. Multivariate statistics showed that age, race, and childhood experiences with domestic violence were significantly related to correctional officers reporting being physically abusive to an intimate partner or family member. These and other findings highlight the need for increased agency prevention efforts and research on the phenomenon of correctional officer-involved domestic violence.     

A Clinical-Corrections Approach: The Failure of a Residential Juvenile Delinquency Treatment Center

Abstract With the incidence of violent juvenile crime and the increasingly limited funds for residential treatment of the adolescent offender, one court jurisdiction (16th Judicial Circuit, Kane County, Illinois) attempted to develop and administer its own residential treatment facility within the walls of its detention facility. This article documents the problems encountered in this endeavor and provides recommendations for other jurisdictions which might be tempted to try to balance the fiscal and rehabilitative demands of this growing population by administering their own residential treatment facilities. The problems addressed in this article pertain to the following areas of difficulty: developing a therapeutic milieu; attracting, training, and evaluating a competent child care staff; and implementing a consistent philosophy of change designed to drive all decision-making within the center.     

Visualizing Homicide: A Research Note

This paper provides some examples of the utility of graphical methods in analyzing data. While such methods are not expected to supplant standard statistical techniques, they can help the researcher in understanding characteristics of the process in ways that cannot be replicated using the standard methods.     

Appearance and Delinquency

This article examines the relationship between appearance and self-reported delinquency. Based on prior research, it is hypothesized that (1) unattractive individuals will be more delinquent, and (2) strain, labeling, and social control variables will mediate the relationship between appearance and delinquency Data from a national sample of adolescent boys support the first hypothesis. Only partial support is provided for the second hypothesis, with social control variables explaining from 9% to 31% of the association between appearance and delinquency. Theoretical and methodological reasons for the limited support of the second hypothesis are discussed.     

Delinquency and Justice

Abstract

In an attempt to demonstrate the value of case study research on delinquency in American Indian communities, Tribal Court juvenile records from one western American Indian community, 1991 through 1998, were analyzed and interviews conducted with community members. Most arrests of juveniles were for alcohol possession and consumption, conduct offenses and status offenses. The most severe offense was simple assault. Youths were more likely to be detained for underage consumption than youths off reservation. Few bookings (26%) resulted in court hearings and all cases resulted in dismissal, deferred adjudication, or deferred sentencing. Girls had higher rates of arrest and detention than males. Interviews identified alcohol consumption and erosion of the extended family as correlates of delinquency.
