Adolescent bullying is a common problem in schools across America. The consequences of bullying are significant, and can include severe psychological trauma and suicide. A better understanding of the mechanisms that link bullying and suicidal ideation is needed in order to develop effective prevention and intervention initiatives. Meaning in life is a potential mechanism that has not been studied in this context. It was hypothesized that meaning in life could serve as both a mediator and a moderator of the relationship between bullying victimization and suicidal ideation. As a mediator, meaning in life is considered to explain why bullying victimization leads to suicidal ideation. As a moderator, meaning in life is considered to buffer the ill effect of bullying victimization on suicidal ideation. Data collected from an ethnically diverse sample of 2,936 (50 % female), 6th–12th grade students from one urban school district in the Northeastern US were used to examine the hypotheses. The model for girls was consistent with mediation (i.e., meaning in life may explain how victimization leads to suicidal ideation). The model for boys was consistent with moderation (i.e., the ill effect of victimization on suicidal ideation was attenuated as meaning in life increased). Implications for prevention are discussed. 相似文献

Red deer is the most valuable game of the fauna in Hungary, and there is a strong need for genetic identification of individuals. For this purpose, 10 tetranucleotide STR markers were developed and amplified in two 5‐plex systems. The study presented here includes the flanking region sequence analysis and the allele nomenclature of the 10 loci as well as the PCR optimization of the DeerPlex I and II. LD pairwise tests and cross‐species similarity analyses showed the 10 loci to be independently inherited. Considerable levels of genetic differences between two subpopulations were recorded, and FST was 0.034 using AMOVA. The average probability of identity (PIave) was at the value of 2.6736 × 10?15. This low value for PIave nearly eliminates false identification. An illegal hunting case solved by DeerPlex is described herein. The calculated likelihood ratio (LR) illustrates the potential of the 10 red deer microsatellite markers for forensic investigations. 相似文献

Baden-Württemberg's innovation system, which is characterised by a high degree of institutionalisation as well as a predominance of incremental innovations and medium technology finds itself in a profound process of transition. The paper discusses whether Baden-Württemberg's strength as an industrial district dominated by mature industries is an impediment or rather an asset with regard to developing new promising technological sectors in the region. The paper focuses on two newly emerging sectors: multimedia and biotechnology. Because of the strong orientation of actors in Baden-Württemberg to established companies in the core industries and the dominance of established organizational networks there is a lack of stimuli for developing new industries. Thus, institutional innovation and new networks are required to speed up the growth of the new industries. Baden-Württemberg can be expected to cope with the transition to the extent that it builds a close connection between its existing sectoral strengths and the new growth industries. 相似文献
