Determinants of Property Crime Among Illicit Opiate Users Outside of Treatment Across Canada

Criminal activities account for a major proportion of the social costs related to illicit drug use. This article examines the factors contributing to property crime activity among a community sample of 653 untreated regular illicit opiate users in 5 Canadian cities (OPICAN study). Multivariate analyses showed the frequency of heroin, cocaine, and crack use, gender, housing status, and past criminal justice involvement as predictors of property crime. Furthermore, crack use had a significantly different impact on property crime depending on housing status and city. These findings underline the need for targeted intervention efforts toward a reduced crime burden.     

The issue of drugs and crime among a sample of incarcerated women

Based on a sample of incarcerated women in Quebec prisons in 1989, this study focuses on drug use and abuse and its relation to crime with a special concern for age of onset, nature of conviction, previous involvement in criminal activities, motivation, and other related variables. The emerging profile of these subjects is one of drug‐related problems rather than a deep involvement in criminality. Within this population of women prisoners a strong link between drugs and crime is still difficult to establish. In conclusion, it is suggested that future research rely more on qualitative analyses to gather a better understanding of the operating processes.     

Adolescents with high mental toughness adapt better to perceived stress: A longitudinal study with Swiss vocational students

A mindset of mental toughness enables an individual to cope successfully with the pressures and demands of life. This 10-month study prospectively examined the association between mental toughness and stress resilience in 865 students (M = 17.86 years, 42.7% girls) from two vocational schools. Within each school, separate cluster analyses identified groups with different profiles of risk (assessed with perceived stress) and adaptation (operationalized with depressive symptoms and life satisfaction). Four clusters emerged characterizing students with well-adjusted (low risk, good adaptation), maladjusted (elevated risk, bad adaptation), deteriorated (low initial risk, worsening adaptation) and resilient profiles (elevated initial risk, improving adaptation). The latter two clusters reported similar levels of mental toughness at baseline, but resilient adolescents scored significantly higher on mental toughness at follow-up. After controlling for possible confounds, baseline toughness levels predicted depressive symptoms and life satisfaction over time. This study shows that mental toughness operates as a stress resilience resource. Mental toughness is, therefore a topic of interest for health specialists working with adolescent populations.     

Socio‐economic status and handedness in two large cohorts of French adults

Left‐and right‐handers have coexisted since the Palaeolithic age. Hand preference is heritable. Moreover, there is extensive evidence of an association between left‐handedness and several fitness costs. In this context, the persistence of the polymorphism is interesting. Here, we explore the associations between socio‐economic status and handedness, analysing data from two large cohorts of adult men and women. Such associations are relevant to an evolutionary approach, as the socio‐economic and the reproductive value are related. Our results partly support the hypothesis that left‐handers have a socio‐economic status advantage, countervailing the health issues. Although the models explain a small proportion of the variance observed, the frequency of left‐handedness is significantly higher: (1) among women of higher educational level; (2) among categories of higher income; and (3) among individuals who have a higher position in the company. The importance of these findings for the evolution of the polymorphism of handedness is discussed.     

Effects of item difficulty on the retrieval of solutions during cognitive skill acquisition: age differences

In cognitive skill learning, shifts to better strategies for obtaining solutions often occur while associations between problems and solutions are being strengthened. In two skill learning experiments, we examined the effects of item difficulty on the retrieval of solutions and the learning of problem-solution associations in younger and older adults. The results of both experiments demonstrated an 'easy effect' in both younger and older adults, such that the retrieval of solutions as well recognition memory for problems was best for the easier items. In addition, a 'hard effect' was found in younger adults, but not in older adults, whereby the retrieval of solutions as well as recognition memory for problems was better for harder items than for medium-difficulty items. The finding that increased computational demands at the item level delayed item memorization and the retrieval of solutions in older adults but not younger adults is consistent with a general-resources account of age-related differences in skill learning.     

Secondary distinctiveness effects: Orthographic distinctiveness and bizarreness effects make independent contributions to memory performance

The secondary distinctiveness effect means that items that are unusual compared to one's general knowledge stored in permanent memory are remembered better than common items. This research studied two forms of secondary‐distinctiveness‐based effects in conjunction: the bizarreness effect and the orthographic distinctiveness (OD) effect. More specifically, an experiment investigated in young adults a possible additive effect of bizarreness and OD effects in free recall performance. Results revealed that in young adults these two secondary‐distinctiveness‐based effects appear to be largely independent and can complement each other to enhance performance. Findings are discussed in light of current distinctiveness theory.     

Effects of voluntary wheel running on heart rate, body temperature, and locomotor activity in response to acute and repeated stressor exposures in rats

Stress often negatively impacts physical and mental health but it has been suggested that voluntary physical activity may benefit health by reducing some of the effects of stress. The present experiments tested whether voluntary exercise can reduce heart rate, core body temperature and locomotor activity responses to acute (novelty or loud noise) or repeated stress (loud noise). After 6 weeks of running-wheel access, rats exposed to a novel environment had reduced heart rate, core body temperature, and locomotor activity responses compared to rats housed under sedentary conditions. In contrast, none of these measures were different between exercised and sedentary rats following acute 30-min noise exposures, at either 85 or 98 dB. Following 10 weeks of running-wheel access, both groups displayed significant habituation of all these responses to 10 consecutive daily 30-min presentations of 98 dB noise stress. However, the extent of habituation of all three responses was significantly enhanced in exercised compared to sedentary animals on the last exposure to noise. These results suggest that in physically active animals, under some conditions, acute responses to stress exposure may be reduced, and response habituation to repeated stress may be enhanced, which ultimately may reduce the negative and cumulative impact of stress.     

Rorty,religion, and humanism

This article offers a review of Richard Rorty’s attempts to come to terms with the role of religion in our public and intellectual life by tracing the key developments in his position, partially in response to the ubiquitous criticisms of his distinction between private and public projects. Since Rorty rejects the possibility of dismissing religion on purely epistemic grounds, he is determined to treat it, instead, as a matter of politics. My suggestion is that, in this respect, Rorty’s position is best construed as that of a humanist rather than a post-modernist. Ultimately, it appears that, in his view, the positive element of religion—i.e. the idea of religion as a social gospel—has been absorbed and transformed into a utopian striving which humanists associate with the ideal of democracy. Hence, in this regard, religion can be considered obsolete. Yet, without explicitly invoking the usual epistemic grounds, Rorty’s arguments for excluding religion from the public sphere remain rather thin, and an interest in reforming rather than excluding religion would have been more consistent with his general outlook.
