New stable phase of non uniform black strings in AdSd{AdS}_d

We consider the non uniform $AdS$ black string equations in arbitrary number of dimension in a perturbative approach up to order 2 and in a non perturbative. We restrict the study in the perturbative approach to the backreacting modes, since they provide the first relevant corrections on the thermodynamical quantities of the solutions. We also present some preliminary results in the construction of non-perturbative solutions, in particular, we present a first part of the non uniform - uniform black string phase diagram. Our results suggests the existence of a new stable phase for $AdS$ non uniform black strings, namely long non uniform black string, with the extra direction length of the order of the $AdS$ curvature.Comment: Results extended. 14 pages, 5 figure

Sustainability of the effects of multisystemic therapy for juvenile delinquents in The Netherlands: effects on delinquency and recidivism

Objectives: The present study focused on the sustainability of the effects of Multisystemic Therapy (MST) on delinquency and recidivism. Methods: A sample of 256 juveniles with severe and persistent antisocial behavior were randomly assigned to MST (147) and Treatment As Usual (TAU) (109) condition. Pre-test assessment took place before the start of MST/control group treatment. Post-test assessment took place at 6 months after termination of the program. Delinquency (parent and adolescent reported) was assessed 6 months after termination of the treatment. Official judicial data were collected to assess recidivism, with a mean length of follow-up of 3.06 years. ANCOVAs and survival analyses were used to test the effectiveness of MST. Results: The multi-informant data showed that MST is effective in diminishing delinquent behavior as reported by adolescents and parents, with d's larger than at post-test assessment immediately after ending of the intervention. The official judicial data, however, suggest that there are no differences between MST and TAU in recidivism. Few and inconsistent moderator effects were found. Conclusions: According to parent and adolescent reports, the beneficial effects of MST were sustained at the follow-up. This was not supported by official data. These results stress the importance of using multi-informant data on delinquency, as each source of information has its own advantages and disadvantages. © 2014 Springer Science+Business Media Dordrecht
