Low internalised restraint predicts criminal recidivism in young female prisoners

CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 5 2009
Ellen Kjelsberg
Background,The Weinberger Adjustment Inventory (WAI) measures social-emotional adjustment along two dimensions: distress and restraint. Four types of adjustment according to this measure have been shown to correlate with criminal recidivism among young male prisoners: reactive (high distress, low restraint), suppressor (high distress, high restraint), non-reactive (low distress, low restraint) and repressor (low distress, high restraint). Aim,To evaluate the predictive potential of the WAI among young female prisoners. Methods,Women under 30 years old, consecutively admitted to one of three Norwegian prisons, were asked to complete the WAI. Most of those eligible (102, 94%) did so. Re-conviction data were collected from the National Crime Register 38 months (SD = 9.0) after release. Results,The overall re-conviction rate was 38%. Rates differed according to the four WAI types: 53% in the non-reactive, 50% in the reactive, 22% in the suppressor and 11% in the repressor group (p = 0.006). Kaplan,Meier analyses showed that group differences were explained by the WAI restraint dimension (p = 0.008). Differences on the distress dimension did not influence re-conviction. Cox regression analysis (adjusting for age at first court conviction and prior offences) found that women with low restraint scores were almost three times as likely to re-offend as women with high restraint scores. Conclusion,The WAI appears to be an effective tool for identifying women who are particularly vulnerable to re-offending. Evidence of high capacity for restraint is protective, regardless of distress levels and even after adjusting for the effect of other criminologically important factors. The findings are suggestive that there may be value in individualising ,treatment' or rehabilitation programmes for prisoners. Copyright © 2009 John Wiley & Sons, Ltd. [source]


Safety pharmacology in the nonclinical assessment of new medicinal products: definition, place, interest and difficulties

FUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 2 2002
Jean-Roger Claude
Until the year 2000 there was no internationally-accepted definition for the terms used in nonclinical pharmacology (primary, secondary pharmacodynamics, discovery, safety pharmacology, etc). Now, after ICH5 (San Diego, November 2000), a harmonisation of the nomenclature is adopted: safety pharmacology is defined as the studies that investigate the potential undesirable pharmacodynamic effects of a medicinal product on physiological functions in relationship to exposure. Consequently, safety pharmacology studies are a part of the safety assessment for a new product, in the same way than toxicological studies, and a basic battery of tests (core battery) has to be conducted prior to the first administration to humans. Safety pharmacology studies are of peculiar interest: they show a good predictive potential for humans, they do not require a large number of laboratory animals, long-term studies, large amount of products and they are more dynamic and more flexible than toxicological studies. Nevertheless, many difficulties occur for the implementation in industry, related to practical and/or scientific problems: location of the studies, routine activity for the pharmacologists, sometimes difficulties in the relationship between toxicologists and pharmacologists, adaptation to the GLP requirements, elaboration of an early relevant scientific programme, necessity to go to contract-labs or to academic research for unusual or for up to date methods, etc. To conclude, a retrospective timetable of the regulatory evolution for the last 10 years will be provided, as an illustration of the worldwide progress in the concept of `harmonisation' for the assessment of new medicinal products.

Applications of Game Theory in Linguistics

LINGUISTICS & LANGUAGE COMPASS (ELECTRONIC), Issue 3 2008
Gerhard Jaeger
The article gives a brief overview over the budding field of game theoretic linguistics, by focusing on game theoretic pragmatics on the one hand, and the usage of evolutionary game theory to model cultural language evolution on the other hand. Two specific applications are discussed in detail: the derivation of scalar implicatures via rational reasoning over communicative strategies, and the predictive potential of an evolutionary interpretation of exemplar dynamics in phonetics.

Correlation of Biochemical and Hematological Changes with Graft Failure Following Pig Heart and Kidney Transplantation in Baboons

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 12 2003
Christoph Knosalla
We have explored biochemical and hematologic parameters that might indicate acute humoral xenograft rejection (AHXR) following pig organ transplantation in baboons. Baboons (n = 15) received an immunosuppressive regimen, and underwent a miniature swine or hDAF kidney (Group 1, n = 6) or heart (Group 2, n = 7) transplantation. Control baboons (Group 3, n = 2) received the immunosuppressive regimen without organ transplantation. Blood chemistry and hematologic parameters were measured daily. Baboon and porcine cytomegalovirus were monitored. In Groups 1 and 2, organ grafts survived for up to 29 days. A plasma fibrinogen of <80 mg/dL on 2 consecutive days, and a serum lactate dehydrogenase of >600 U/L and aspartate transaminase of >300 U/L, were associated with the development of AHXR in both heart and kidney grafts. In Group 1, a decrease in platelet count of >150 000/,L within 3 days, or a count of <50 000/,L, were associated with AHXR. In Group 2, a creatine phosphokinase of >500 U/L was associated with graft failure. In Group 3, no abnormalities were observed. The possibility that porcine CMV may play a role in graft injury could not be excluded. Noninvasive parameters were identified that have predictive potential for AHXR. Monitoring of these might enable therapeutic intervention to reverse rejection. [source]
