Multidimensional item response theory (MIRT) was used to study the construct validity of the Static-2002R, an actuarial scale for the assessment of reoffending among adult men who sexually offended. Using a sample of 2,569 individuals with a history of sexual crime, exploratory factor analysis (EFA) extracted three factors: Persistence/Paraphilia, General Criminality, and Youthful Stranger Aggression. MIRT confirmed the factor structure identified in the EFA model and provided item-level data on discrimination and difficulty. All Static-2002R items showed moderate to very high discrimination and covered a wide range of risk levels (i.e., difficulty). MIRT analyses attested to the construct validity of the scale, as no items were identified as problematic and the resulting factor structure was consistent with that of earlier studies. Considering the stability of results pertaining to the factor structure of the Static-2002R and the advantages of dimensional scoring, we recommend the integration of dimensional scores in the scale.

We applied offending trajectory analyses to 387 men adjudicated for child sexual exploitation material (CSEM) offenses. After an average of 20 years, we found two trajectories of sexual offending and violent offending: one that peaked in late adolescence and was associated with higher rates of crimes, and one that peaked in the 30s and was associated with a lower rate of crime. We found four trajectories when modeling any crime. The findings highlight the heterogeneity of men with CSEM offenses. Although lifelong patterns of numerous sexual crimes were uncommon, men with more sexual crimes had greater indicators of sexual interest in children and a younger age of first contact with police. CSEM offenses were rarely the first offense in their criminal trajectories. As such, early intervention targeting youth before they are further advanced in their criminal careers may also reduce future CSEM offending.

Limited research exists on the impact of psychopathy within romantic relationships. We examined mental and physical health consequences reported by intimate partners of individuals with psychopathic traits. Additionally, we explored whether psychopathy severity and coping impacted the severity of posttraumatic stress disorder and depression symptoms. Four hundred fifty-seven former and current intimate partners of individuals with psychopathic traits were recruited from online support groups. Victims reported a variety of abusive experiences and various negative symptomatology involving emotional, biological, behavioral, cognitive, and interpersonal consequences. Psychopathy severity and maladaptive coping were significantly related to increased PTSD and depression, while adaptive coping was only related to decreased depression. Regression analyses revealed that experiencing many forms of victimization predicted increased PTSD and depression symptoms. Examining the specific consequences experienced by intimate partners of individuals with psychopathic traits can aid the development of individualized treatment interventions aimed at symptom mitigation, recovery, and prevention of future victimization.

Preventive detention provisions in the US and Canada assume we can identify, in advance, individuals at high risk for sexual recidivism. To test this assumption, 377 adult males with a history of sexual offending were followed for 20 years using Canadian national criminal history records and Internet searches. Using previously collected information, a high risk/high need (HRHN) subgroup was identified based on an unusually high levels of criminogenic needs ( n = 190, average age of 38 years; 83% White, 13% Indigenous, 4% other). A well above average subgroup of 99 individuals was then identified based on high Static-99R (6+) and Static-2002R (7+) scores. In the HRHN group, 40% reoffended sexually. STATIC HRHN norms overestimated sexual recidivism at 5 years (Static-99R, E/O = 1.44; Static-2002R, E/O = 1.72) but were well calibrated for longer follow-up periods (20 years: Static-99R, E/0 = 1.00; Static-2002R, E/O = 1.16). The overall sexual recidivism rate for the well above average subgroup was 52.1% after 20 years, and 74.3% for any violent recidivism. The highest risk individuals (top 1%) had rates in the 60%–70% range. We conclude that some individuals present a high risk for sexual recidivism, and can be identified using currently available methods.

Objective: The purpose of this study was to develop new 10-year recidivism rate norms as well as to update 5-year norms for the Static-99R risk tool for routine/complete samples. We also present the extrapolated sexual recidivism rates from these new 10-year norms for follow-up periods of 11 to 20 years. Hypotheses: We hypothesized that absolute-recidivism base rates (B02; i.e., the intercept centered on the median score of 2) would vary; however, the relative predictive accuracy (i.e., discrimination; B1) would be stable across samples. In addition, compared with the estimated sexual recidivism rates with a fixed 5-year follow-up time, the estimated rates with a fixed 10-year follow-up time would be expected to be consistently higher across the Static-99R scores. Method: The current study included 12 independent samples (N = 7,224 for the 5-year recidivism rate norms; N = 1,599 [k = 6] for the 10-year norms) classified as routine/complete samples, that is, relatively random samples from a correctional system. Logistic regression parameters (B02 and B1) across the studies were aggregated using fixed-effect meta-analyses. Results: There was statistically significant variability in the base rates (B02), whereas the between-sample variability in the relative-risk parameters (B1) was no more than would be expected by chance. As expected, the 10-year base rates were approximately 1.5 times higher than the 5-year base rates (7.20% vs. 4.58%), and the extrapolated 20-year sexual recidivism rates were approximately double the observed 5-year sexual recidivism rates. Conclusions: The current study provides empirical evidence to estimate 5- and 10-year sexual recidivism rates based on Static-99R total scores. Evaluators who are especially concerned about long-term sexual recidivism risk (e.g., civil commitment) can report the expected sexual recidivism risk based on the new 10-year norms and the extrapolated sexual recidivism rates for follow-up periods of 11 to 20 years.

The accuracy of risk assessment tools for Asian populations has received relatively little research attention. This study evaluated one of the most widely used static risk assessment tools - Static-99R - for assessing the likelihood of recidivism among men convicted of a sexual crime in South Korea. Overall, this South Korean sample ( N = 8207) appeared to have a higher risk (more paraphilic interests, more sexual/general criminality) than the Static-99R normative samples (who were mostly White individuals from Western countries). Despite the differences, Static-99R was able to discriminate recidivists from nonrecidivists in South Korea, with AUC values similar to that observed in the normative samples (e.g., 0.72 for sexual recidivism). In terms of calibration, the observed sexual recidivism rates of the current sample were higher than the international routine/complete normative samples but lower than the high-risk/high-need normative samples ( E/ O = 0.75 and 1.26, respectively). Consequently, evaluators in South Korea can have reasonable confidence in the ability of Static-99R to rank individuals according to their relative likelihood of sexual recidivism.

Although considerable research has found overall moderate predictive validity of Static-99R, a sex offender risk prediction tool, relatively little research has addressed its potential for cultural bias. This prospective study evaluated the predictive validity of Static-99R across the three major ethnic groups (White, n = 789; Black, n = 466; Hispanic, n = 719) in the state of California. Static-99R was able to discriminate recidivists from nonrecidivists among White, Black, and Hispanic sex offenders (all area under the curve [AUC] values >.70; odds ratios >1.39). Base rates (at a Static-99R score of 2) with a fixed 5-year follow-up across ethnic groups were very similar (2.4%-3.0%) but were significantly lower than the norms (5.6%). The current findings support the use of Static-99R in risk assessment procedures for sex offenders of White, Black, and Hispanic heritage, but it should be used with caution in estimating absolute sexual recidivism rates, particularly for Hispanic sex offenders.

Although there is considerable research on Caucasian sexual offenders, there has been much less research on sex offenders of Asian heritage. The current study compared East Asian (e.g., Chinese, Japanese, and Korean) sex offenders in British Columbia (B.C.), Canada, and other B.C. sex offenders on items and total score of Static-99R. This study included all provincially sentenced adult male sexual offenders (n = 4580) supervised in the community by B. C. Corrections (including 122 East Asian sex offenders). Sexual, violent, any crime, and any recidivism (including technical violations) data were collected with an average follow-up 4.3 years. The total scores of Static-99R were similar between East Asian sex offenders and other ethnic groups (M = 2.0 vs. M = 2.4). East Asian offenders scored significantly lower than other ethnic offenders on several items measuring general criminality (e.g., prior non-sexual violence, prior sentencing dates, and any prior sex offenses). In contrast, Asian offenders appeared to be more paraphilic (e.g., any convictions for non-contact sex offenses). Lastly, Static-99R significantly predicts sexual, violent, and criminal among sex offenders of East Asian heritage.

There has been little research on the sexual offending behavior of different racial groups. This study compares the characteristics and risk factors for American, non-Hispanic Whites ( n =797) and Blacks ( n = 788) who had been convicted of a sexual crime in New Jersey. The results indicated that Whites appeared more paraphilic whereas Blacks displayed higher antisociality. Despite the differences, however, the Static-99R, sexual recidivism risk tool, predicted equally well for both racial groups: Whites (area under the curve [AUC] = .76) and Blacks (AUC = .78). The findings suggest that there may be opportunities to improve treatment for the individuals at risk for sexual offending by tailoring interventions to the distinctive risk-relevant characteristics of Whites and Blacks.

Purpose To evaluate the province-wide implementation of the Strategic Training Initiative in Community Supervision (STICS) in British Columbia, Canada. Methods Probation officers (PO) audio recorded a sample of their supervision sessions with probationers prior to and after receiving STICS training. Training involved teaching POs to apply cognitive-behavioral interventions to address the criminogenic needs of their clients. Both the general and violent recidivism rates of probationers were measured using a national criminal history database. Recidivism was defined as a new conviction. Results After training, audio recordings showed clear improvements in the content of discussions and the intervention techniques used by POs. Compared to a random sample of probationers supervised prior to STICS training, clients of STICS-trained POs had significantly lower 2-year general recidivism rates (43.0% vs. 61.4%; OR = 0.48, 95% CI [0.37, 0.61]) and violent recidivism rates (14.9% vs. 21.2%; OR = 0.65, 95% CI [0.48, 0.89]). Conclusions Training POs in how to address criminogenic needs using cognitive-behavioral interventions was associated with significant reductions in client recidivism. This project demonstrated that a community corrections agency can benefit from an evidence-based approach to supervision.

Sexual offenders are more likely to have a history of psychiatric hospitalization compared with the general population. This finding suggests that a history of psychiatric hospitalization is a plausible risk factor for the initiation of sexual crimes. It is less clear, however, whether psychiatric hospitalization is associated with risk factors for criminal recidivism. Consequently, the current study examined the correlates of psychiatric hospitalization and its relevance for risk assessment in a sample of sexual offenders on community supervision (N = 947). In this sample, a history of psychiatric hospitalization significantly increased the rate of sexual recidivism (hazard ratio = 1.95). After controlling for well-established risk factors, however, the association was no longer statistically significant. Consequently, this study supported an indirect effect of a history of psychiatric hospitalization, such that the association between psychiatric symptoms and recidivism was mediated by criminogenic needs (e.g., poor general self-regulation, loneliness, and social rejection). Replication studies are needed to confirm this association, and to further understand the link between mental illness and recidivism for sexual offenders. (PsycINFO Database Record

The predictive validity of the Static-99 measures with ethnic minorities in the United States has only recently been assessed with mixed results. We assessed the predictive validity of the Static-99 and Static-99R with a sample of Latino sex offenders ( N = 483) as well as with two subsamples (U.S.-born, including Puerto Rico, and non-U.S.-born). The overall sexual recidivism rate was very low (1.9%). Both the Static-99 measures were able to predict sexual recidivism for offenders born in the United States and Puerto Rico, but neither was effective in doing so for other Latino immigrants. Calibration analyses ( N = 303) of the Static-99R were consistent with the literature and provided support for the potential use of the measure with Latinos born in the United States and Puerto Rico. These findings and their implications are discussed as they pertain to the assessment of Latino sex offenders.

Today's enterprises increasingly rely on the Web to support their operations, global business alliances, and integration of their business processes with those of their suppliers, partners, and customers. In order to stay competitive, businesses, must also respond to changing business and competitive environments in near real-time. This requires that the architecture and design of business systems and applications should allow quick reconfiguration as well as collaboration among distributed software components. Existing software design methodologies often lack the Web focus and explicit support for componentization. This paper presents a methodology for requirements analysis and high-level design, specifically for component-based Web applications.Using the Web page as the fundamental building block of Web applications, the proposed methodology introduces page and component classifications, and a set of tags to implement link semantics. Based on these constructs, the methodology then specifies procedures for requirements analysis and design. A running business example is used to illustrate various stages, of the analysis and design process.

The e-tailer's dilemma refers to the difficulty web-based retailers (or e-tailers) have experienced in achieving profitability. The problem centers on the need to increase effective (purchasing) visitors and on the increased costs associated with the electronic commerce infrastructure upgrades necessary to service these additional visitors. This may lead e-tailers into a cycle of achieving increased revenues that are merely offset by rising costs. There are ample examples where commonly employed metrics (unique visitors, page views, sales, etc.) suggest success while companies struggle to obtain profitability. This paper examines several aspects of this dilemma. The formalization of both the tangible and intangible aspects of an electronic commerce infrastructure is proposed. Next, an intuitive, utility-based model to help describe and interpret e-tail visitor dynamics is developed. Finally, a visitor function model of e-tail profitability incorporating necessary infrastructure improvements and visitor characteristics is developed.

Submergence of plant organs perturbs homeostasis by limiting diffusion of oxygen, carbon dioxide and ethylene. In rice (Oryza sativa L.), the haplotype at the multigenic SUBMERGENCE1 (SUB1) locus determines whether plants survive prolonged submergence. SUB1 encodes two or three transcription factors of the group VII ethylene response factor family: SUB1A, SUB1B and SUB1C. The presence of SUB1A-1 and its strong submergence-triggered ethylene-mediated induction confers submergence tolerance through a quiescence survival strategy that inhibits gibberellin (GA)-induced carbohydrate consumption and elongation growth. SUB1C is invariably present and acts downstream of the enhancement of GA responsiveness during submergence. In this study, heterologous ectopic expression of rice SUB1A and SUB1C in Arabidopsis thaliana was used to explore conserved mechanisms of action associated with these genes using developmental, physiological and molecular metrics. As in rice transgenic plants that ectopically express SUB1A-1, Arabidopsis transgenic plants that constitutively express SUB1A displayed GA insensitivity and abscisic acid hypersensitivity. Ectopic SUB1C expression had more limited effects on development, stress responses and the transcriptome. Observation of a delayed flowering phenotype in lines over-expressing SUB1A led to the finding that inhibition of floral initiation is a component of the quiescence survival strategy in rice. Together, these analyses demonstrate conserved as well as specific roles for group VII ethylene response factors in integration of abiotic responses with development.

Identifying higher-level interface elements with which the user interacts on an e-business application should not be an arbitrary task. Unlike conventional applications, Web-based ones provide information and/or functions with the user via clickable links. These unique characteristics of Web-based applications call for a more methodical approach to identifying higher-level e-business application interface elements, their organisation, and its presentation to the user to make information consumption more efficient and effective. In this paper, we propose an interface specification method founded on the concepts of meta-information structure and information structure, as well as taking account of various page, link, and component types.
