This book proposes an explicit recognition of criminology as a moral science – that is, an empirically rigorous social science that takes full account of the presence and role of values in people’s reasoning and motivation. This endeavour requires input from both criminologists and moral philosophers, and careful dialogue between them, so the book...

The study foun...
Article
Programs of offender rehabilitation aim to reduce reoffending and promote a noncriminal lifestyle. In contrast to the ‘nothing works’ doctrine of the 1970s, research on ‘what works’ has shown a desirable mean effect of 10–20% less reoffending. Cognitive–behavioral programs, hierarchical therapeutic communities, multisystemic therapy, education, voc...

... Das restriktive Klima in Bezug auf vollzugsöffnende Maßnahmen trifft insbesondere Sexualstraftäter.1 Obwohl einschlägige Rückfallraten oft unter 10 % liegen (Lösel, Carl & Link, 2023;Wößner, 2021) und andere Straftätergruppen deutlich häufiger und schneller rückfällig werden (Jehle, Albrecht, Hohmann-Fricke & Tetal, 2020), werden Sexualstraftäter als besonderes Sicherheitsrisiko wahrgenommen (Suhling & Rehder, 2009). Stück et al. (2022) fassen die bisherige Forschung dahingehend zusammen, dass Gefangene eher Lockerungen erhalten, wenn sie älter sind, die deutsche Staatsangehörigkeit haben, in einer festen Partnerschaft leben, nicht suchtgefährdet sind und eine weniger umfangreiche kriminelle Vorgeschichte aufweisen. ...
... Previous review studies have already provided an overview of protective factors for antisocial behavior (e.g., Loeber, 1990;Lösel & Bender, 2017;Lösel & Farrington, 2012;Portnoy et al., 2013). Lösel and Farrington (2012), for example, provided a brief narrative review of research findings on protective factors and found several individual, family, school, peer, and neighborhood factors that could decrease the probability of youth violence. ...
... The researcher's awareness of the reality of the messy game development process is an integral part of keeping the informants engaged in relationships or other means to motivate the busy game developers. Maintaining a high retention rate in longitudinal research requires persistent communication, frequent follow-up contacts, and tangible non-monetary incentives to make it feel rewarding to the participants [32,48,76,88] (see also [24,47,85]). One of those attempts in the game research discipline can be found in Kultima's ethnographic study of the game Noita by Nolla Games (2019). ...

Wir stellten hierzu fest, dass Therapieauflagen bei entlassenen Sexualstraftätern, die nicht in sozialtherapeutischer Behandlung waren, mit weniger Rückfälligkeit assoziiert waren (Carl & Lösel, 2021a). Besonders deutlich war dieser Effekt für in Haft nicht behandelte Sexualstraftäter. ...

Similar to general sexual offence treatment evaluations (see Carl & Lösel, 2021;Olver & Wong, 2011), high levels of participant drop-out are common in longitudinal universitybased sexual harm prevention studies (e.g., Salazar et al., 2014;Wong et al., 2020). Therefore, alongside our primary and secondary analyses, we also assessed the degree to which TG participants' attitudes, subjective normative beliefs, and perceived behavioral control influenced their intention to complete The Pathways program. ...
