Delinquency and reputational orientations of adolescent at-risk and not-at-risk males and females

This research investigated differences in delinquent activities and the reputational orientations of at-risk and not-at-risk male and female adolescents. Initially, we sought to establish that adolescent males and females differed in these respects. This was found to be the case: males (n = 722) scored significantly higher than females (n = 738) on seven self-reported delinquency variables and on eight reputation enhancement variables pertaining to social deviance, non-conforming reputation, and power/evaluation private identity. When a sample of 31 at-risk females was subsequently pair-wise age matched with 31 not-at-risk females, at-risk females scored significantly higher on all delinquency variables other than school misdemeanors. These at-risk females also scored significantly higher on four reputation enhancement variables relating to social deviance and non-conformity. Given that at-risk females did not differ from their not-at-risk counterparts in level of involvement in school misdemeanors, we sought to determine whether this was also the case for at-risk and not-at-risk males. An age-matched sample of 91 pairs revealed that at-risk males reported significantly higher involvement than not-at-risk males in all aspects of delinquency, including school misdemeanors. They also sought a more non-conforming reputation. To explore the relationships between delinquency and reputation enhancement, a canonical correlation analysis was performed. All findings are discussed in the light of reputation enhancement theory. © 2008 Taylor & Franci

Inflammatory markers predict late cardiac events in patients who are exhausted after percutaneous coronary intervention.

Contains fulltext : 48049.pdf (publisher's version ) (Closed access)Chronic inflammation is one of the main underlying mechanisms in the development of coronary artery disease (CAD). We investigated the prognostic value of inflammatory markers for cardiac events occurring more than 6 months after percutaneous coronary intervention (PCI), i.e. late cardiac events, furthermore we investigated the temporal stability of these markers. Exhausted patients (234) recently treated by successful PCI were studied. Serum samples collected about 6 weeks after PCI (baseline), 6 and 18 months after baseline were analyzed for CRP, IL-6, tumour necrosis factor (TNF-alpha), IL-10, IL-1ra, IL-8 and neopterin. In the mean cardiac follow-up of 24 months, 25 late cardiac events occurred. Cox proportional hazards analysis was used to determine the prognostic value. Elevated concentrations of IL-6 at baseline and 6 months later increased the risk of late cardiac events (RR 3.9, CI 1.7-9.0, p 0.00 and RR 3.6, CI 1.6-8.5, p 0.00). Elevated concentrations of CRP and IL-10 at baseline also increased the risk of late cardiac events (RR 2.5, CI 1.1-5.7, p 0.04 and RR 2.5, CI 1.1-5.6, p 0.03) as did IL-1 receptor antagonist at 6 months (RR 2.6, CI 1.1-6.1, p 0.04). Temporal stability was high for most markers, but highest for IL-6. These results support the assumption that chronic inflammation is a pathophysiological mechanism in the development of CAD

Virtual Visualization System for Growth of Tobacco Root

International audienceVisualization study on the growth of virtual plant roots is of great significance to enhance the overall level of research on virtual plant growth. In this study, with the tobacco root as the object, its growth was divided by systematic analysis into three stages: root emergence, root growth, and root branching. Through the quantitative analysis of the morphological data of the tobacco root and in combination with results of previous studies, the tobacco root growth, branching and other models were established, and parameter values of the models were extracted. On this basis, computer graphics technology was applied to establish a virtual visualization system for tobacco root growth that should be capable of simulating root growth and computing indicators of roots including the number, length, density, etc. Results indicated that this system can do a better job of simulating the morphological features for the tobacco root and virtually displaying the process of tobacco root growth in a more realistic way
