  • desistance from sexual and other violent offending among child sexual abusers observations using the sex offender treatment intervention and progress scale
    Criminal Justice and Behavior, 2017
    Co-Authors: Michael P Lasher, Robert J Mcgrath
    Abstract:

    Most sex offenders appear to desist from sexual and other violent offending; however, research on this population has historically focused more on the characteristics of individuals who persist offending versus those who desist from offending. The present study examined change patterns of 563 child sexual abusers’ scores on the Sex Offender Treatment Intervention and Progress Scale, a dynamic risk measure, at three points of time over 2 years. Individuals who did versus did not commit a new serious offense, defined as a new sexual or other violent offense, at 5-year follow-up were contrasted. Desisters demonstrated most changes during their first year in treatment, whereas change among persisters more often occurred during their second year in treatment. All classes of offenders made gains in addressing dynamic risk related to sexually specific needs, whereas desisters made significantly greater gains in social stability needs. Findings are discussed in light of treatment dose allocation and community ree...

  • a developmental taxonomy of juvenile sex offenders for theory research and prevention the adolescent limited and the high rate slow desister
    Criminal Justice and Behavior, 2012
    Co-Authors: Patrick Lussier, Chantal Van Den Berg, Catrien Bijleveld, J Hendriks
    Abstract:

    The current study investigates the offending trajectories of juvenile sex offenders (JSOs) across and beyond adolescence. In doing so, the study examines the number, the rate, and the shape of nonsexual and sexual offending trajectories in a sample of JSOs followed retrospectively and prospectively from late childhood to adulthood. Using semiparametric group-based modeling, the study reveals the presence of five distinctive nonsexual offending and two sexual offending trajectories: adolescent-limited and high-rate slow desisters. The study does not find strong evidence of synchronicity between nonsexual and sexual trajectories, suggesting that the current taxonomy of antisocial behaviors may offer a limited perspective on sex offender types. Furthermore, sexual trajectories do not differ much across sex offender types, suggesting that the findings might be generalized to child and peer abusers. The study findings offer supporting evidence for the presence of two distinct JSO types with important implications for theory, research, and interventions. Language: en

  • modular mini hydrocyclone desilter type of 30 mm an experimental and optimization study
    Journal of Petroleum Science and Engineering, 2015
    Co-Authors: Jose Lucas Mogno, J M Da Silva, Isabele Cristina Icalho, Carlos Henrique Ataide, Claudio Roberto Duarte
    Abstract:

    Abstract Mini-hydrocyclones are separators widely investigated with a view to expanding their applications in operations that require efficient separation of fine particles. The purpose of this study was to analyze the effects of design and operating variables, including the vortex finder length and height of the cylindrical body, cone frustum angle, underflow diameter and feed pressure, on the separation efficiency of a modular hydrocyclone with a characteristic diameter of 30 mm especially developed for use in the petroleum industry. The particulate matter consisted of phosphate rock with a density of 3.15 g/cm 3 and an average diameter of 4.5 μm, used at a concentration of 0.5 vol% in the preparation of the suspension. The results were analyzed statistically and correlations or empirical models were generated. The proposed empirical models offered a good description of the collected experimental data. A methodology for multi-objective optimization of these models was used and an optimal geometry was proposed. The optimal geometry showed a total separation efficiency of more than 89% and a flow ratio of less than 35%.
