Despite broad consensus that most juvenile crimes are committed with peers, many questions regarding developmental and individual differences in criminal style (i.e., co-offending vs. solo offending) remain unanswered. Using prospective 3-year longitudinal data from 937 14- to 17-year-old serious male offenders, the present study investigates whether youths tend to offend alone, in groups, or a combination of the two; whether these patterns change with age; and whether youths who engage in a particular style share distinguishing characteristics. Trajectory analyses examining criminal styles over age revealed that, while most youth evinced both types of offending, two distinct groups emerged: an increasingly solo offender trajectory (83%); and a mixed style offender trajectory (17%). Alternate analyses revealed (5.5%) exclusively solo offenders (i.e., only committed solo offenses over 3 years). There were no significant differences between groups in individuals?? reported number of friends, quality of friendships, or extraversion. However, the increasingly solo and exclusively solo offenders reported more psychosocial maturity, lower rates of anxiety, fewer psychopathic traits, less gang involvement and less self reported offending than mixed style offenders. Findings suggest that increasingly and exclusively solo offenders are not loners, as they are sometimes portrayed, and that exclusively solo offending during adolescence, while rare and previously misunderstood, may not be a risk factor in and of itself. 相似文献

Adolescent alcohol involvement is associated with numerous negative outcomes, but also appears to have positive correlates,
including subjective well-being. Additional research is needed to understand these paradoxical findings. The current study
examines alcohol use, adverse alcohol-related (and other substance-related) consequences, and subjective well being in adolescence,
and prediction to problem alcohol use in early adulthood. Participants in this longitudinal study, which extended from age
11 to age 21, were 208 rural teens (109 girls) and their families. Covariates included early substance use, early conduct
problems, early depressed mood, gender, and parent educational attainment. Structural equation modeling showed that subjective
well-being at age 16 positively predicted increased alcohol use at age 18. Alcohol use was not a significant predictor of
subjective well-being; however, alcohol use at age 18 positively predicted alcohol problems at age 21, even while controlling
for earlier adverse consequences and other predictors. Results help to further elucidate both the negative and positive correlates
of underage drinking, and support the value of delaying alcohol initiation. 相似文献

Prior studies have documented linkages between mental disorder and both offending and victimization. However, few studies
have examined the violent offending–violent victimization overlap among mentally disordered individuals and none have examined
the factors that are jointly related to their covariation. Here, we assess this overlap during the first ten weeks following
hospital discharge among a large sample of psychiatric patients from three large cities. Findings indicate that: (1) violent
offending and violent victimization show substantial covariation; (2) although each of the two outcomes were predicted by
a few unique risk factors, several risk factors were similarly predictive of both outcomes; and (3) even after adjusting for
demographic, clinical, and social risk factors, the correlation between violent offending and violent victimization remained
robust. Implications for theory, research, and policy are highlighted. 相似文献

Telephone surveys have been a principle means of learning about the attitudes and behaviors of citizens and voters. The single
mode telephone survey, however, is increasingly threatened by rising costs, the declining use of landline telephones, and
declining participation rates. One solution to these problems has been the introduction of mixed-mode surveys. However, such
designs are relatively new and questions about their representativeness and the intricacies of the methodology remain. We
report on the representativeness of a post election mixed-mode (Internet and mail) survey design of 2006 general election
voters. We compare sample respondent means to sample frame means on key demographic characteristics and examine how mail and
Internet respondents differed in terms of attitudes, behaviors and demographics. We find that overall the Internet respondents
were representative of the population and that respondent choice of mode did not influence item response. We conclude that
mixed-mode designs may allow researchers to ask important questions about political behavior from their desktops. 相似文献

This article looks at collective decisions over the limits to consumption of a private good that produces a collective bad and studies the way in which these decisions are affected by changes in the distribution of wealth. It shows that a democratic voting program reduces the maximum permissible consumption of the good, whereas a benevolent planner, and a voting program dominated by the rich, will increase this level. It also shows that, under all programs, production of the bad is driven down by increases in inequality. 相似文献

Organised criminality is a great concern for national/international security. The demonstration of complex crimes is increasingly dependant on knowledge distributed within law-enforcement agencies and scientific disciplines. This separation of knowledge creates difficulties in reconstructing and prosecuting such crimes. Basic interdisciplinary research in drug intelligence combined with crime analysis, forensic intelligence, and traditional law enforcement investigation is leading to important advances in crime investigation support. Laboratory results constitute one highly dependable source of information that is both reliable and testable. Their operational use can support investigation and even provide undetected connections or organisation of structure. The foremost difficulties encountered by drug analysts are not principally of a chemical or analytical nature, but methodologies to extract parameters or features that are deemed to be crucial for handling and contextualising drug profiling data. An organised memory has been developed in order to provide accurate, timely, useful and meaningful information for linking spatially and temporally distinct events on a national and international level (including cross-border phenomena). Literature has already pointed out that forensic case data are amenable for use in an intelligence perspective if data and knowledge of specialised actors are appropriately organised, shared and processed. As a particular form of forensic case data, the authors' research focuses on parameters obtained through the systematic physical and chemical profiling of samples of illicit drugs. The procedure is used to infer and characterise links between samples that originate from the same and different seizures. The discussion will not, however, focus on how samples are actually analysed and compared as substantial literature on this topic already exists. Rather, attention is primarily drawn to an active and close collaboration between magistrates, forensic scientists, law enforcement investigators and crime analysts from different institutions with the aim of generating, using and validating relevant profiling case data as integral part of investigative and crime analysis processes. Original advances are highlighted through experiences from criminal investigations of offences related to the unlawful importation, exportation, supply and possession of illicit drugs. 相似文献

Abstract: The Atomic Force Microscope (AFM) is capable of imaging fingerprint ridges on polished brass substrates at an unprecedented level of detail. While exposure to elevated humidity at ambient or slightly raised temperatures does not change the image appreciably, subsequent brief heating in a flame results in complete loss of the sweat deposit and the appearance of pits and trenches. Localized elemental analysis (using EDAX, coupled with SEM imaging) shows the presence of the constituents of salt in the initial deposits. Together with water and atmospheric oxygen—and with thermal enhancement—these are capable of driving a surface corrosion process. This process is sufficiently localized that it has the potential to generate a durable negative topographical image of the fingerprint. AFM examination of surface regions between ridges revealed small deposits (probably microscopic "spatter" of sweat components or transferred particulates) that may ultimately limit the level of ridge detail analysis. 相似文献

Purpose
Knowledge about offenders and knowledge about victims has traditionally been undertaken without formal consideration of the overlap among the two. A small but growing research agenda has examined the extent of this overlap. At the same time, there has been a minimal amount of research regarding offending and victimization among minority youth, and this is most apparent with respect to Hispanics, who have been increasing in population in the United States.Materials &; Methods
This study explores the joint, longitudinal overlap between offending and victimization among a sample of Puerto Rican youth from the Bronx, New York.Results
Results indicate: (1) an overlap between offending and victimization that persists over time, (2) a considerable overlap in the number, type, direction, and magnitude of the effect of individual, familial, peer, and contextual factors on both offending and victimization, (3) some of the factors related to offending were only relevant at baseline and not for the growth in offending but that several factors were associated with the growth in victimization, and (4) various risk factors could not explain much of the overlap between offending and victimization.Conclusions
Theoretical, policy, and future research directions are addressed. 相似文献79.
Deterrence theory has been a centerpiece of theoretical and empirical research in criminology. Largely due to the early work of Beccaria however, much of this research has focused on estimating the effect of the certainty of punishment, or the costs of crime, on criminal offending. Although the benefits/rewards of crime are as important as the costs, conceptualization and operationalization of this portion of the decision-making process has only recently accumulated. In an effort to provide a counterpart to the summary statements available regarding the costs of crime, this paper undertakes a statistical summary of the empirical studies that have examined the benefits/offending relationship, with specific attention paid not only to the overall relationship, but also to several key moderators. Using 40 specific estimates from 13 studies since 1990, the analysis provides evidence of a positive and significant relationship between benefits and offending, but that the overall relationship varies in several ways. Directions for future research are outlined. 相似文献
