The existing literature seriously misinterprets the available evidence on the predictability of high rate criminal offending
and thus the potential value of statistical treatment rules that impose stiffer punishments on offenders with higher predicted
risk of recidivism. The misinterpretation results from the failure to take account of the fact that the data used in existing
risk assessment exercises come from environments characterized by informal (and sometimes formal) attempts by judges and other
actors to base penal treatments on expected recidivism. Findings of little or no predictive power for baseline covariates
may simply indicate the efficient use of the available information. We lay out the problem in detail, provide examples from
several literatures and then consider general solutions to the problem.

Despite the immense popularity of offender profiling as both a topic of fascination for the general public as well as an academic
field of study, concerns have been raised about the development of this area of scientific inquiry. The present study provides
a preliminary step towards moving the field forward as it reviews the type and quality of studies dealing with offender profiling
over the past 31 years. Based on a content analysis of 132 published articles, the review indicates that researchers investigating
this phenomenon rarely publish multiple articles, and they are generally reported across many different journals, thereby
making knowledge synthesis and knowledge transfer problematic. In addition, the majority of papers published in the area are
discussion pieces (e.g., discussing what profiling is, how profiles are constructed, and when profiling is useful), despite
the fact that the processes underlying offender profiling are still not well understood. Finally, although peer-reviewed articles
exploring this topic have steadily increased, the statistical sophistication of these studies is sorely lacking, with most
including no statistics or formal analyses of data. Suggestions for future research and recommendations to streamline efforts
in this field are provided based on the results of this review.

Originally developed in biology, capture-recapture methodologies have increasingly been integrated into the study of human
populations to provide estimates of the size of “hidden populations.” This paper explores the validity of one capture-recapture
model—Zelterman’s (1988) truncated Poisson estimator—used to estimate the size of the marijuana cultivation industry in Quebec, Canada. The capture–recapture
analysis draws on arrest data to estimate the number of marijuana growers “at risk of being arrested” for a period of five
years (1998–2002). Estimates are provided for growers involved in two different techniques: (1) soil-based growing, and (2)
hydroponics. In addition, the study develops an original method to estimate the prevalence of cultivation sites “at risk of
detection.” A first set of findings shows that the cultivation industry is substantial; the estimated prevalence of growers
compares to estimates of marijuana dealers in the province. Capture–recapture estimates are also used to compare the risks
of being arrested for different types of offenders. Results indicate that hydroponic growers—those involved in large scale
and sophisticated sites—face lower enforcement-related risks than growers involved in smaller enterprises. The significance
of these findings is discussed in the context of the widespread development, both in Europe and in North America, of a successful
domestic production-driven, rather than importation-driven, marijuana trade.

The Revised Conflict Tactics Scales (CTS2) are widely used to measure intimate partner aggression. Various aspects of the
CTS2 and its subscales have been examined, e.g. factor structure, internal consistency, and validity, but little or no evidence
exists regarding the stability of the self-report of aggression on the CTS2 This study examines the stability of reports of
aggression against a partner on the CTS2 among 82 men court-mandated to a batterer intervention program. At both testing times
men reported on aggression occurring in the year prior to beginning treatment. Using variety scores, stability of report was
strong for psychological aggression (r = 0.69), physical assault (r = 0.76), injury (r = 0.70), and negotiation (r = 0.60), but weaker for sexual coercion (r = 0.30). Implications for the use of the CTS2 in court-mandated populations are discussed.

Using four categories of accuracy (true positive, false positive, true negative, false negative), this study explored (1)
how accurately intimate partner violence (IPV) victims are able to assess their risk of re-abuse; and (2) potential predictors
of accuracy. Women seeking help for IPV (N = 246) rated the likelihood that they would experience physical re-abuse in the coming year and then reported 18 months later
whether those risks had been realized. Victim assessments were more likely to be right than wrong, and were subject to neither
a pessimistic nor optimistic bias. In the multivariate analysis, significant/marginally significant predictors of the accuracy
categories were the history of violence from this and former partners, level of substance use, PTSD symptoms, and the recency
of the violence. Among the more robust findings were the connection between level of stalking and true positives, and between
substance use and false negatives. This study suggests that victim assessments have significant potential to inform practice,
and deserve further exploration.

When Morality Opposes Justice: Conservatives Have Moral Intuitions that Liberals may not Recognize 总被引:5,自引:2,他引:3
Researchers in moral psychology and social justice have agreed that morality is about matters of harm, rights, and justice.
On this definition of morality, conservative opposition to social justice programs appears to be immoral, and has been explained
as a product of various non-moral processes such as system justification or social dominance orientation. In this article
we argue that, from an anthropological perspective, the moral domain is usually much broader, encompassing many more aspects
of social life and valuing institutions as much or more than individuals. We present theoretical and empirical reasons for
believing that there are five psychological systems that provide the foundations for the world’s many moralities. The five
foundations are psychological preparations for detecting and reacting emotionally to issues related to harm/care, fairness/reciprocity,
ingroup/loyalty, authority/respect, and purity/sanctity. Political liberals have moral intuitions primarily based upon the
first two foundations, and therefore misunderstand the moral motivations of political conservatives, who generally rely upon
all five foundations.

Inherent to any substantive social change is the disruption of the status quo. To the extent that individuals are motivated
to preserve the current social system (e.g., Jost & Banaji, British Journal of Social Psychology, 33, 1–27, 1994), even social change in pursuit of positive goals might evoke ambivalent reactions. Although activist groups might elicit
positivity because they are assumed to have positive qualities and they seek positive goals, they might evoke negativity because
their actions disrupt the current social system. These experiments examined two different forms of disruption of the status
quo. In Experiment 1, a group gaining power elicited greater ambivalence than a group losing power, regardless of the valence
of the group’s goal. Importantly, the conditions that evoked ambivalence did not inhibit behavioral support. Experiment 2
found that a new group elicited more ambivalence than an established group when pursuing a positive goal. Consistent with
theories emphasizing maintenance of the status quo, these findings demonstrate that attitudes toward activist groups do not
derive solely from self-interest.

Much research on adolescent delinquency pivots on the notion of peer influence. The peer effect that is typically employed
emphasizes the transmission of behaviors and attitudes between adolescents who are directly linked. In this paper, we argue
that to rely solely on those direct social ties to capture peer influence oversimplifies the realities of adolescent society.
We use data from the National Longitudinal Study of Adolescent Health to show that indirect peer relations can exercise independent
influences on adolescent delinquency. Adolescents actively draw on the examples of friends of friends, and even more distal
peers, as they develop their repertoires of action and identity. We argue, however, that this behavior actually reflects adolescents’
ongoing struggle to impress their closest friends and to preserve their social circle. Indeed, the extent to which adolescents
are willing to model the behavior of indirect contacts seems to decline as that behavior becomes more dissimilar from that
of their close friends. Our findings dovetail with an account of the adolescent as a rational actor who struggles for social
acceptance in a complex peer environment which offers conflicting behavioral models.

In jurisdictions across the United States, the mandated arrest of individuals perpetrating domestic violence crimes termed
“mandatory arrest” or “pro-arrest” policies has become a key policy solution to the issue of domestic violence. The purposes
of the policies are to standardize the police response to, and increase the number of, arrests stemming from domestic violence
incidents by removing or reducing police discretion to arrest. In 1994, the New York state legislature passed the Family Protection
and Domestic Violence Intervention Act, which contained provisions enacting a mandatory arrest statute. Using information
from 183 callers to a telephone helpline for victims of domestic violence, we describe four unintended consequences of the
policy: “unwanted,” “dual,” “retaliatory,” and “no” arrest. Bi- and multivariate analyses are used to identify victim and
perpetrator sociodemographic, situational, and legal factors associated with each arrest type. Results are discussed in the
context of the effects of mandatory arrest policies and minimizing problems associated with it in the future.

This paper discusses issues related to measuring organized crime as they have become manifest in the Dutch contribution to
the EU Organised Crime Threat Assessment (OCTA). It intends to convey to a wider academic community certain issues of definition,
methodology and accountability, understanding the NTA process in terms of the communication of risks in a context of competitive
defining institutions.
