Taking the Pulse: perceptions of crime trends and community safety and support for crime control methods in the Canadian Prairies

The present study analyzed crime survey data extracted from the 2012 Saskatchewan Taking the Pulse survey on a sample of 1,700 adult Saskatchewan residents. The focus was on examining perceptions of crime trends, perceived effectiveness of various methods for controlling crime, and their sociodemographic correlates. The majority of survey respondents perceived crime in general to be on the rise (37%) or to have not changed at all (48%) over the last three years. Individuals who perceived crime to have decreased were significantly more likely to support alternatives to punishment as effective methods for reducing crime, while individuals who perceived crime to be on the rise were twice as likely to support the use of punitive methods. Perceptions of community safety were unrelated to preference for one crime reduction method over another. Education level was inversely related to crime trend perceptions (r = -.14) and preference for punitive methods to reduce crime (r = -.20). Finally, the results of logistic regression indicated higher levels of education, higher income, and perceptions of crime decreasing were all uniquely associated with a preference for alternatives to punishment in reducing crime. In these analyses, younger age was predictive of a preference for alternatives in reducing youth crime, while urban residential setting was associated with a preference for alternatives to punishment in reducing crime in general

Firesetting Reoffending: A Meta-Analysis

Despite the significant adverse consequences of deliberate firesetting, it has been unclear what proportion of individuals repeat this problematic behavior, owing to methodological differences and large variability in reported reoffending rates. A meta-analysis of 25 samples of untreated adults and children with a history of firesetting, examining reoffending over a follow-up period, was conducted. The base rates of reoffending from this meta-analysis indicated that between 57% and 66% of untreated firesetters engage in general reoffending, between 8% and 10% engage in criminal arson, and around 20% engage in deliberate firesetting behavior. The odds of firesetting during the follow-up period were 5 times greater for known firesetters in comparison with other offenders. Clinical and criminological correlates of reoffending, including age, are examined. Implications for enabling evidence-based practice with this population, including defensible risk assessments and treatment provision, are discussed

The Principle of Symmetric Criticality in General Relativity

We consider a version of Palais' Principle of Symmetric Criticality (PSC) that is applicable to the Lie symmetry reduction of Lagrangian field theories. PSC asserts that, given a group action, for any group-invariant Lagrangian the equations obtained by restriction of Euler-Lagrange equations to group-invariant fields are equivalent to the Euler-Lagrange equations of a canonically defined, symmetry-reduced Lagrangian. We investigate the validity of PSC for local gravitational theories built from a metric. It is shown that there are two independent conditions which must be satisfied for PSC to be valid. One of these conditions, obtained previously in the context of transverse symmetry group actions, provides a generalization of the well-known unimodularity condition that arises in spatially homogeneous cosmological models. The other condition seems to be new. The conditions that determine the validity of PSC are equivalent to pointwise conditions on the group action alone. These results are illustrated with a variety of examples from general relativity. It is straightforward to generalize all of our results to any relativistic field theory.Comment: 46 pages, Plain TeX, references added in revised versio

The Development and Validation of the Firesetting Questionnaire

This research developed and evaluated a measure to examine fire-specific constructs relevant to fire misuse. In the first study, using UK community members asked to disclose deliberate firesetting, we tested a large pool of theoretically informed questionnaire items. First, we found that 1 in 10 adults reported setting a deliberate fire that they had not been apprehended for. Then, exploratory and confirmatory factor analyses suggested an eight-factor measure with broader coverage of theoretically-informed risk factors, relative to previous measures, and acceptable test item validity and robust internal consistencies. In the second study, we tested the Firesetting Questionnaire with imprisoned men who held a record of firesetting and imprisoned and community comparisons. The findings illustrated psychometric robustness. Our results suggest that the Firesetting Questionnaire has the potential to be a useful clinical tool for highlighting fire-specific treatment needs and informing clinical formulation and associated risk management

Does specialized psychological treatment for offending reduce recidivism? a meta-analysis examining staff and program variables as predictors of treatment effectiveness

A meta-analysis was conducted to examine whether specialized psychological offense treatments were associated with reductions in offense specific and non-offense specific recidivism. Staff and treatment program moderators were also explored. The review examined 68 studies and 55,604 individuals who had offended. Three specialized treatments were examined: sexual offense, domestic violence, and general violence programs. Across all programs, offense specific recidivism was 13.4% for treated individuals and 19.4% for untreated comparisons over an average follow up of 66.1 months. Relative reductions in offense specific recidivism were 32.6% for sexual offense programs, 36.0% for domestic violence programs, and 24.3% for general violence programs. All programs were also associated with significant reductions in non-offense specific recidivism. Overall, treatment effectiveness appeared improved when programs received consistent hands-on input from a qualified registered psychologist and facilitating staff were provided with clinical supervision. Numerous program variables appeared important for optimizing the effectiveness of specialized psychological offense programs (e.g., arousal reconditioning for sexual offense programs, treatment approach for domestic violence programs). The findings show that such treatments are associated with robust reductions in offense specific and nonoffense specific recidivism. We urge treatment providers to pay particular attention to staffing and program implementation variables for optimal recidivism reductions

Common variation near CDKN1A, POLD3 and SHROOM2 influences colorectal cancer risk

We performed a meta-analysis of five genome-wide association studies to identify common variants influencing colorectal cancer (CRC) risk comprising 8,682 cases and 9,649 controls. Replication analysis was performed in case-control sets totaling 21,096 cases and 19,555 controls. We identified three new CRC risk loci at 6p21 (rs1321311, near CDKN1A; P = 1.14 × 10(-10)), 11q13.4 (rs3824999, intronic to POLD3; P = 3.65 × 10(-10)) and Xp22.2 (rs5934683, near SHROOM2; P = 7.30 × 10(-10)) This brings the number of independent loci associated with CRC risk to 20 and provides further insight into the genetic architecture of inherited susceptibility to CRC.Swedish Research Council et al.Manuscrip

Dynamic Sexual Offense Risk Assessment Using the VRS-SO With Indeterminate Sentenced Men

Indeterminate detention (ID) is a high stakes sanction reserved for exceptionally high risk-high need (HRHN) persons who are deemed to pose an undue risk to public safety. It is one of the most extreme measures that is routinely taken by justice systems to manage sexual violence risk and prevent sexual and violent recidivism. Naturally, risk assessment is most frequently employed as a mechanism to keep dangerous people in custody; but seldom is risk assessment viewed as a possible ticket out for men with an ID designation who have made substantive risk changes and whose risk can be safely managed in the community. This article features applications of a dynamic sexual violence risk assessment and treatment planning tool, the Violence Risk Scale-Sexual Offense version (VRS-SO), with ID individuals and other HRHN men, to assess risk in a dynamic manner to inform risk management efforts and release decisions. VRS-SO data on an ID sample are presented along with clinical illustrations of dynamic risk assessment. Several propositions are made with supporting data from VRS-SO normative research with treated sexual offending samples regarding the use of dynamic tools with ID men and the perils and pitfalls of relying solely on static measures. Ultimately, dynamic risk instruments can be used to track progress and monitor risk change over multiple assessments to inform release and reintegration decisions with ID persons. In this regard, dynamic assessment has the potential to help, rather than hinder, reintegration of ID sentenced persons and can inform safe, fair, and humane decisions

Moving Coframes II. Regularization and Theoretical Foundations

The primary goal of this paper is to provide a rigorous theoretical justification of Cartan’s method of moving frames for arbitrary finite-dimensional Lie group actions on manifolds. The general theorems are based a new regularized version of the moving frame algorithm, which is of both theoretical and practical use. Applications include a new approach to the construction and classification of differential invariants and invariant differential operators on jet bundles, as well as equivalence, symmetry, and rigidity theorems for submanifolds under general transformation groups. The method also leads to complete classifications of generating systems of differential invariants, explicit commutation formulae for the associated invariant differential operators, and a general classification theorem for syzygies of the higher order differentiated differential invariants. A variety of illustrative examples demonstrate how the method can be directly applied to practical problems arising in geometry, invariant theory, and differential equations

Moving Coframes I. A Practical Algorithm

This is the first in a series of papers devoted to the development and applications of a new general theory of moving frames. In this paper, we formulate a practical and easy to implement explicit method to compute moving frames, invariant differential forms, differential invariants and invariant differential operators, and solve general equivalence problems for both finite-dimensional Lie group actions and infinite Lie pseudo-groups. A wide variety of applications, ranging from differential equations to differential geometry to computer vision are presented. The theoretical justifications for the moving coframe algorithm will appear in the next paper in this series
