Purpose

Failing to deal with missing data patterns effectively may result in biased parameter estimates and ultimately may produce inaccurate results and conclusions. The vast majority of criminological research has addressed this issue with listwise deletion (LD) and multiple imputation (MI) techniques. Identifying the specific covariates that directly contribute to patterns of missingness is highly important in deciding which technique to use. One of the more surprising omissions from the identified list of covariates is the potential role of genetic influences in the development of missingness.

Methods

The current study addresses this gap in the literature by estimating genetic (A), shared environmental (C), and the nonshared environmental (E) influences on missingness across measures of delinquency and self-control within a longitudinal sample of twin and sibling pairs.

Results

The results indicated that genetic influences explain a significant portion of the variance in missing values related to both delinquency and self-control.

Conclusions

Current methodological techniques aimed at addressing missing data should be amended to take genetic influences into account. Such modifications and the implications of the findings for future research are discussed.  相似文献

The search for improvements in the management and quality of public services seems to be a constant in all public administrations, and there is an ever-increasing use of management techniques and models from the business sector. The aim of this paper is to show which management systems are being used by Spanish local governments to improve their management in terms of economy, quality and the environment. Our analysis is based on a questionnaire sent to Spanish local governments about the tools they use and the factors that influence their implementation. The results show that more efforts are necessary to implement performance measurement and total quality management, but they also show some positive aspects, such as the usefulness of performance measurement and its application to decisions in those local governments that have implemented it.  相似文献

ABSTRACT

The development and validation of empirically sound measures that operationalize the Triarchic model of psychopathy among youth is currently in the nascent stage. The present study aimed to examine the psychometric properties of a brief refined measure of the Triarchic model of psychopathy based on the Youth Psychopathic Traits Inventory (YPI-Tri-S) among a mixed-gender school sample of 782 youth (M?=?15.87 years, SD?=?1.72) from Portugal. Confirmatory factor analysis offered support for the theoretically expected three-factor structure. Cross-gender measurement invariance using the present sample and cross-sample measurement invariance of the YPI-Tri-S using a previously collected forensic sample of institutionalized males was established. The YPI-Tri-S showed adequate psychometric properties in terms of discriminant validity, convergent validity, concurrent criterion-related validity, known-groups validity, and internal consistency. Findings indicate that YPI-Tri-S is a valuable brief and psychometrically reliable and valid self-report measure of the Triarchic model of psychopathy for use in diverse samples of youth.  相似文献

Left realists continue to offer progressive ways of studying and solving various types of crime in the streets, in the “suites,” and in intimate relationships. This article briefly describes the central themes, assumptions, and concepts of left realism and charts new directions in research, theory, and policy. Special attention is devoted to using new electronic technologies and to responding to the rabid corporatization of institutions of higher learning.  相似文献

Since the 1970s, many studies have enhanced a social scientific understanding of the lethal and non-lethal physical abuse of women during and after separation and divorce, but less than a handful have examined sexual assaults on rural women who want to leave, are trying to leave, or who have left spouses or live-in male partners. Further, none of the work done so far on this problem has examined the role of collective efficacy. The results presented here help fill these research gaps and call into question the common assumption that there is more collective control on criminal behavior in rural settings. Moreover, our exploratory qualitative data show that collective efficacy can take many shapes and forms, and often what is perceived as the “common good” may actually be behaviors and discourses that threaten the health and well-being of women seeking freedom from abusive male partners.  相似文献

Childhood obesity has become a public health epidemic, and currently a battle exists over how to frame and address this problem. This paper explores how public policy approaches can be employed to address obesity. We present the argument that obesity should be viewed as the consequence of a "toxic environment" rather than the result of the population failing to take enough "personal responsibility." In order to make progress in decreasing the prevalence of obesity, we must shift our view of obesity away from the medical model (which focuses on the individual) to a public health model (which focuses on the population). At the same time, we must be sensitive to the problem of weight bias. Potential obstacles to taking a public policy approach are identified, as well as suggestions on how to overcome them.  相似文献

This study evaluated the extent to which divorce creates the “divided world of the child,” as well as consequences of this “divided world” for long‐term adjustment. An ethnically diverse sample of 1,375 young‐adult university students completed retrospective measures of parental nurturance and involvement, and current measures of psychosocial adjustment and troubled ruminations about parents. Results indicated that reports of maternal and paternal nurturance and involvement were closely related in intact families but uncorrelated in divorced families. Across family forms, the total amount of nurturance or involvement received was positively associated with self‐esteem, purpose in life, life satisfaction, friendship quality and satisfaction, and academic performance; and negatively related to distress, romantic relationship problems, and troubled ruminations about parents. Mother‐father differences in nurturance and involvement showed a largely opposite set of relationships. Implications for family court practices are discussed.  相似文献

Using social network analysis (SNA), we propose a model for targeting criminal networks. The model we present here is a revised version of our existing model (Schwartz and Rouselle in IALEIA Journal, 18(1):18–14, 2008), which itself builds on Steve Borgatti’s SNA-based key player approach. Whereas Borgatti’s approach focuses solely on actors’ network positions, our model also incorporates the relative strength or potency of actors, as well as the strength of the relationships binding network actors.

Data and safety monitoring boards (DSMBs) provide independent oversight to bio-medical clinical trials, ensuring safe and ethical treatment of research participants, data quality, and credibility of study findings. Recently, the type of research monitored by DSMBs has been expanded to include randomized clinical trials of behavioral and psychosocial interventions in community and justice based settings. This paper focuses on the development and role of a DSMB created by the National Institute on Drug Abuse (NIDA) to monitor six multi-site clinical trials conducted within the Criminal Justice–Drug Abuse Treatment Studies (CJ-DATS). We believe this is one of the first such applications of formal DSMBs in justice settings. Special attention is given to developing processes for measuring and monitoring a range of implementation issues for research conducted within criminal justice settings. Lessons learned and recommendations to enhance future DSMB work within this area are discussed.  相似文献
