    Abstract The aim of the present study was to examine the psychometric properties of the German version of the revised Violence Risk Appraisal Guide (VRAG), the VRAG-R. Therefore, VRAG-R ratings were made retrospectively in an Austrian sample of 534 individuals convicted of a sexual offense who were followed up with an average of 7.62 years. The VRAG-R showed large effect sizes for the predictive accuracy of violent (AUC = .75) and general recidivism (AUC = .78) and significant but rather small effect sizes (AUC = .63 and .61, respectively) in predicting any sexual and sexual contact recidivism. Furthermore, for the prediction of violent recidivism but not for sexual recidivism the VRAG-R was incrementally predictive beyond the Sex Offender Risk Appraisal Guide (SORAG) and the Static-99. Finally, the VRAG-R absolute recidivism rates for the risk bins showed satisfactory calibration properties. Taken together, the results of the present study support the cross-national utility of the VRAG-R and its use in applied risk assessment settings also in German-speaking countries.

  3. Article ; Online: The predictive and incremental validity of ADHD beyond the VRAG-R in a high-risk sample of young offenders.

    Abstract The VRAG-R is a well-established actuarial risk-assessment instrument, which was originally developed for assessing violent recidivism risk in adult male offenders. Whether or not the VRAG-R can also predict violent recidivism in young offenders is unclear so far. In the emergence of juvenile offending, attention-deficit/hyperactivity disorder (ADHD) seems to be of major importance suggesting that it could be relevant for risk assessment as well. Thus, we examined the predictive accuracy of the VRAG-R in a high-risk sample of N = 106 (M = 18.3 years, SD = 1.8) young offenders and assessed the incremental predictive validity of ADHD symptomatology beyond the VRAG-R. Within a mean follow-up time of M = 13 years (SD = 1.2), n = 65 (62.5%) young offenders recidivated with a violent offense. We found large effect sizes for the prediction of violent and general recidivism and re-incarcerations using the VRAG-R sum scores. Current ADHD symptomatology added incremental predictive validity beyond the VRAG-R sum scores concerning the prediction of general recidivism but not of violent recidivism. The results supported the use of the VRAG-R for predicting violent recidivism in young offenders. Because ADHD symptomatology improves the predictive performance of the VRAG-R regarding general recidivism, we argue that addressing ADHD symptoms more intensively in the juvenile justice system is of particular importance concerning a successful long-term risk management in adolescents and young adults.

    Abstract Der Violence Risk Appraisal Guide Revised (VRAG-R) ist ein aktuarisches kriminalprognostisches Instrument, welches für die Einschätzung des Rückfallrisikos gewalttätiger inklusive sexueller hands-on Delikte entwickelt wurde. Die prädiktive Validität des VRAG-R wurde retrospektiv an einer Stichprobe von Sexualstraftätern aus dem österreichischen Strafvollzug mittels ROC-Analysen untersucht. Der VRAG-R zeigte eine gute Diskriminationsfähigkeit zwischen zukünftigen Rückfälligen und Nicht-Rückfälligen. Nach den vorliegenden Ergebnissen ist die Nützlichkeit des revidierten VRAG für die Vorhersage des gewalttätigen inklusive sexuellen Rückfalls bei Sexualstraftätern im deutschsprachigen Raum zu unterstützen.

In this note, we show that if two trees T1 and T2 of order at least two are r-equitably k-colorable for r ≥ 1 and k ≥ 3, then all trees obtained by adding an arbitrary edge between T1 and T2 are also r-equitably k-colorable.

    Abstract A fundamental part of the adolescent self is formed through interaction with intimates, usually family members whose roles are reasonably well-defined. However, donor siblings-children who share a sperm donor-lack social scripts for interacting with one another, particularly when they are raised in different households. Moreover, they are often challenged to figure out their relationship to newly discovered genetic relatives. This article examines how donor-conceived teens and young adults navigate relationships with their half siblings and form intimate relationships. Drawing on Garfinkel's concept of indexing, or the use of familiar categories to make sense of new situations, these youth rely upon their personal knowledge of friends and family to figure out what kinds of relationship they can develop with donor siblings. Based on interviews with 62 youth aged 14-28, who had their own social media accounts and who had chosen to establish contact with their donor siblings, the articles discusses the three stages most donor siblings go through-"anticipation", "first contact", and "relationship building"-and the way those stages shape individual identity formation. In the course of the analysis, the article also explores whether interaction with donor siblings affected individual's sense of identity and whether feelings of closeness with donor siblings differ for youth raised as solo children versus those who have siblings with whom they share a household. For those who report feeling close, youth describe how intimacy is sustained and negotiated at a distance. Finally, as much as youth pick and choose intimates from their larger network, the article also argues that their collective identity as related-kin members remains.

    Title translation "Population and xenograft" investigation. Preliminary results.
    Abstract The chronic shortage of human organs is the argument for xenotransplantation. In emergencies, acceptability is closely linked to the benefit. Little information is available on attitudes towards xenotransplantation. A poll of the attitudes was carried out, based on a questionnaire with targeted questions and background information. The goal of the study was to have a better understanding of people's attitudes towards xenotransplantation and to know the eventual changes in the answers after having been given information. For 75% of the sample, xenotransplantation would be a future biotechnology. The animal sources that would be considered for xenotransplantation were the pig and monkey. A period of ten years or more is necessary for 69% of the respondents before xenografts are performed routinely; for 19%, five years or less are needed. Human organ donation should be continued, according to 90% of the sample. Roughly, 46.4% support xenotransplantation, though in the case of a life-or-death situation acceptance reaches 65.7%. This level is higher (77%) for relatives or unknown people (71%); 74% of respondents were in favour of using normal animals and a large majority (88%) support research on xenotransplantation. A good level of confidence in medical biotechnology research and practice is suggested by this study, contrary to the results of a European survey on biotechnology.

    Abstract A fundamental part of the adolescent self is formed through interaction with intimates, usually family members whose roles are reasonably well-defined. However, donor siblings—children who share a sperm donor—lack social scripts for interacting with one another, particularly when they are raised in different households. Moreover, they are often challenged to figure out their relationship to newly discovered genetic relatives. This article examines how donor-conceived teens and young adults navigate relationships with their half siblings and form intimate relationships. Drawing on Garfinkel’s concept of indexing, or the use of familiar categories to make sense of new situations, these youth rely upon their personal knowledge of friends and family to figure out what kinds of relationship they can develop with donor siblings.
