This study of 2,722 adolescents aged 14-18 years explored whether parental involvement can protect against adolescent suicide attempts. Compared to their counterparts suicide attempters were more likely to have been in trouble with the police, to report lower levels of parental interest and academic motivation, and to report suicidal ideation and using alcohol or an illegal drug when they feel stressed. They were also less likely to reside with both parents. The association between parental involvement and suicidal behaviour was not stronger for sons than for daughters or for adolescents who had experienced family disruption than for those who grew up in two-parent families. 相似文献

Validation of a 16-locus fluorescent multiplex system 总被引:24,自引:0,他引:24

STR multiplexes have been indispensable for the efficient genotyping of forensic samples. The PowerPlex 16 System contains the coreCODIS loci, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, CSF1PO, FGA, THOI, TPOX, vWA, the sex determinant locus, amelogenin, and two pentanucleotide STR loci, Penta D and Penta E. This multiplex satisfies the locus requirements for most national databases and is the most efficient currently available system due to its single PCR amplification. To provide the groundwork for judicial acceptance, including the publication of primer sequences, and to evaluate laboratory-to-laboratory variation, a developmental validation for casework on this commercially available system was performed in 24 laboratories and produced the following conclusions. Amplification was reliable on a variety of thermal cyclers and product could be analyzed on either an ABI PRISM 310 Genetic Analyzer or an ABI PRISM 377 DNA Sequencer. Genotyping using single source samples was consistent between 0.25 and 2 ng of input DNA template with a few laboratories obtaining complete genotypes at 0.0625 ng. However, heterozygote allele imbalance (<60% peak height balance) caused by stochastic effects was observed at a rate of 13% with 0.125 ng DNA and 22% at 0.0625 ng DNA. Mixture analyses were done using a total of 1 ng of DNA template. Most alleles were detected in mixtures of 4 to 1 and some minor alleles were detected in mixtures of 19 to 1. Optimum amplification cycle number was dependent on the sensitivity of the detection instrument used and could also be adjusted to accommodate larger amounts of DNA on solid supports such as FTA paper. Reaction conditions including volume, annealing temperature, and concentrations of primer, AmpliTaq Gold, and magnesium were shown to be optimal yet robust enough to withstand moderate variations without affecting genotype analysis. Environmental, matrix and standard source analyses revealed an ability to obtain complete genotypes in all sample types except those exposed to 80 degrees C for 12-48 days. Finally, comparison of genotype results from the PowerPlex 16 System with other commercially available systems on non-probative reference and forensic samples showed consistent results. 相似文献

A study of 30 cases of violence from a total sample of 199 cases of infant abductions between the years 1983 and 2000 included a subsample of six (or 20%) where the kidnapping was by cesarean section. The six cases are classified by type of crime. Four cases were classified as personal cause homicide, subtype cesarean section homicide; one case classified as personal cause, subtype domestic homicide, and one case classified as a criminal enterprise homicide. The behavioral profiles of the abductors included a confidence style approach to the victim mother, deception, and planning of the cesarean section. The forensic psychodynamics suggest a dual motive to cement a failing partner relationship and to fulfill a childbearing and delivery fantasy. Cesarean section murder suggests a new category of personal cause homicide. 相似文献

Abstract: Efforts to design merit‐based appointment systems for the boards of government agencies, boards and commissions (abcs) have gained greater priority over the past decade in order to enhance public confidence in the integrity of the political process, improve the governance of organizations operating at arm's length from ministers, and reduce the risks to the public interest and public purse that come with incompetent boards. The Nova Scotia reform experience in this regard is instructive because this province's appointment regime not only encompasses a legislative committee veto over ministerial appointments, a power unique to this province in the Canadian and comparative Westminster systems, but also uniquely sets the merit standard as relative‐merit, that is, the appointment of the most qualified of all applicants, and not merely a qualified candidate. This article reviews this provincial experience and concludes that a merit‐based appointment system that pursues relative merit can be created but only by restricting the authority of ministers to a veto over the appointment of candidates nominated by the abcs themselves. Sommaire: Ces dix demières années, les efforts déployés pour concevoir des systemes de nomination au mérite pour les conseils d'administration d'organismes, des régies et des commissions du gouvernement ont obtenu une priorité beaucoup plus grande, et cela, afin de rehausser la confiance du public envers I'intégrite du processus politique, d'ameliorer la gouvernance d'organismes fonctionnant sans contrôle ministériel direct et de réduire les risques que représentent les conseils incompétents pour le bien et les deniers publics. L'expérience de la réforme entreprise en NouvelleÉcosse est à cet égard instructive pour les partisans de la réforme. Le régime de nomination de cette province comporte non seulement un droit de veto de la part d'un comité législatif sur les nominations ministéielles, pouvoir unique à cette province dans le systéme canadien et le systéme comparatif de Westminster, mais il établit également la norme de mérite comme un mérite relatif, c'est‐à‐dire la nomination de la personne la mieux qualifiée parmi tous les candidats et non simplement la nomination d'une personne qualifiée. Le présent article examine I'expérience de cette province et conclut qu'un système de nomination au mérite visant le mérite relatif peut être mis en place, mais seulernent à condition de limiter le pouvoir des ministres à opposer leur veto à la nomination de candidats par les organismes, régies et commissions gouvernementaux. 相似文献

Regulatory Commitment to Negotiated Agreements: Evidence from the United States, Germany, The Netherlands, and France 总被引:1,自引:0,他引:1
Negotiated Agreements (NAs) are arrangements between firms and regulators in which firms voluntarily agree to reduce their pollution. This article analyzes the institutional features that facilitate or hamper the implementation of NAs. We illustrate the analysis with case studies on the implementation of NAs in the United States, Germany, the Netherlands, and France. We find that NAs are implemented when regulators are able to commit credibly to the objectives of NAs. Institutional environments marked by fragmentation of power and open access in policymaking reduce regulatory credibility and thus hamper the implementation of NAs. 相似文献

Grassroots environmental activism among Latin America's poor has altered the debate over environmental policy, social welfare, and citizenship. Yet the question remains whether this social mobilization of the poor is part of a larger trend toward broader environmental concerns and democratic political participation, or a shortlived movement susceptible to the same pressures that have dissolved community mobilization in the past. This article compares Brazil with other Latin American and European countries in surveys of environmental awareness, concerns, and reported behavior. It finds that Brazilians residing in the urban periphery link their own local environmental concerns to more global considerations, and that concern for and activism on environmental issues is positively related to wider community involvement. 相似文献

The purpose of this study was to examine differences in empathy between offender and nonoffender youth. Seventy-six male and 33 female juvenile offenders between the ages of 12 and 18 years and 33 male and 33 female nonoffenders between the ages of 15 and 19 years comprised the samples for this study. Measures of empathy, altruism, and social support were administered to all participants and then the participants were analyzed for status group differences. Only 1 dimension of empathy, emotional tone, was found to be significantly different based on group status. Gender differences were found for both status groups for another dimension of empathy, personal distress. Among offender and nonoffender youth, females yielded higher scores in personal distress than did males. Emotional tone and family structure were found to be the most predictive variables of offender status. Findings were discussed based on previous research and implications for interventions were addressed.Evaluation and Special Programs 相似文献
