This study examines the association of self-perceptions with sixth to eighth graders' exposure to mixed-sex and dating contexts. It contrasts two hypotheses: the stress hypothesis, which suggests that the transition to romantic relationships will be associated with declines in self-esteem, especially for girls, and the leisure hypothesis, which suggests that movement into a desired role in an emotionally positive social context will be associated with positive emotions and higher self-esteem. Results indicate that adolescents experience mixed-sex settings positively, and that comfort with the other sex (for girls) and more time spent with the other sex (for boys) are predictive of more positive self-perceptions. Activity diary data suggest that these differences are due to differences in the emotional climate of same- and mixed-sex settings, rather than to the activities adolescents engage in with same- and mixed-sex groups. Dating boys who are less interested in dating experience lower self-esteem. Results are discussed in light of the transitional nature of mixed-sex relationships in early adolescence and the preparatory role played by same-sex friendships. 相似文献

The death of a parent in childhood represents a profound psychological insult. Although a number of studies have examined rates of depression and anxiety in bereaved children, less attention has been given to understanding predictors of children's adjustment to the loss. Data are presented from 83 families with school-age children in which a parent had died of cancer in the preceding 18 months. The surviving parent and one randomly selected child completed individual interviews conducted by a clinician in the families' homes. Using multiple regression, potential predictors of children's psychosocial adjustment to parental death are examined and their relative importance is discussed. Among the predictors considered were child's age, child's gender, deceased parent's gender, time since death, length of illness, presence of siblings, and parental communication patterns. The child's perception of the surviving parent's level of openness in parental communication was found to be significantly correlated with lower levels of depressive symptoms and state anxiety in bereaved children. Boys reported lower levels of depressive symptoms than did girls, and older children reported lower levels of state anxiety than did younger children. 相似文献

A validation study for the extraction and analysis of DNA from human nail material and its application to forensic casework. 总被引:5,自引:0,他引:5

A validation study was conducted to demonstrate that deoxyribonucleic acid (DNA) could be successfully extracted from human nail material and analyzed using short tandem repeat (STR) profiling and/or mitochondrial DNA (mtDNA) sequencing. This study involved the development of a DNA extraction protocol that includes a cleaning procedure designed to remove external contaminants (e.g., biological, chemical). This protocol was used to test human nail material that had been soaked in whole blood from a second donor and coated with gold-palladium to simulate scanning electron microscopic analysis. The results showed no indication of a mixture and were consistent with that of the nail donor. Fresh human nail material usually yielded both STR profiles and mtDNA sequence information; however, aged human nail material (approximately eight years old) yielded only mtDNA sequence information. Upon completion of the validation study, the extraction protocol was used for the analysis of a torn fingernail fragment recovered from the scene of a violent homicide in 1983. A partial STR profile and mtDNA sequence information indicated that the fingernail fragment was excluded as originating from the suspect and was, in fact, consistent with originating from one of the victims. 相似文献

The purpose of this article is to examine the self-reported sexual attitudes and behaviors of adolescents living in the Midwest. A survey was administered to 463 African American youths ages 11–19. The results indicate that intent to have sexual intercourse, reported likelihood toward having sexual intercourse, and whether participants felt that they would have sex in the next 3 months were predictors of whether they had sexual intercourse at the 3-month follow-up. The results also revealed that the opinions of referent others did not predict sexual intercourse at 3 months. Negative attitudes toward condoms did predict condom use at 3 months and the opinions of referent others also predicted condom use at 3 months. Limitations as well as future research are also discussed. 相似文献

Recent histories of Ancient Greece describe a transition from customary law to public criminal justice between 800 and 400 B.C. This narrative contains three pieces of evidence against the presumption that prisons are a public good and government must provide incarcerations. First, before the rise of a formal government, Ancient Greece had a functioning system of criminal law enforcement. Second, the timeline surrounding the rise of government institutions in Ancient Greece originated with Solon’s penal reforms. Lastly, the rise of a government system was more the result of private rather than public interest. 相似文献

Despite the recognition that the integration of refugees and expellees into west Germany has been one of the success stories of the post‐war period, little light has been shed on the process of political integration of this group into the political system of the nascent Federal Republic. As the ‘newcomers’ were prevented from organising themselves in political or cultural organisations, the only legitimate way of exercising political influence was the way through the licensed parties. The CDU/CSU as a conglomerate of liberal and conservative traditions made use of its historic opportunity to adapt its flexible party apparatus and encourage refugee participation. Thereby, it made an important contribution to the political representation of refugee demands as well as attracting a large proportion of the newcomers’ votes. 相似文献

Dans le présent article, le lien entre la distribution des revenus et les taux de croissance est analysé de manière empirique à l'aide d'une série de régressions. A l'opposé des études antérieures, la relation en question est examinée à la fois dans l'espace et dans le temps: l'auteur construit un panel basé sur une période de 40 ans et sur un échantillon homogène, composé par dix pays de l'Europe de l'Ouest. Démontrant une corrélation négative significative entre les deux variables, les résultats confirment la théorie qui identifie l'inégalité comme un frein à la croissance. Il en suit que les facteurs concernant la distribution du revenu se répercutent sur la croissance économique à moyen et long terme au même titre que les variables macroéconomiques traditionnelles. Ces résultats sont discutés à la lumière de deux transformations économiques récentes, le cas de la croissance américaine d'une part et la globalisation des économies d'autre part. 相似文献

Many law enforcement agencies are currently responding to the problem of online crime by establishing proactive investigative units that track criminals on the Internet. Not only do these specialized teams face problems in the area of emerging technology, they are also faced with handling emerging legal issues. The current research examined the issue of the entrapment defense, and how previously established physical realm doctrine could be applied to the investigation of online crimes such as child pornography. Relying on previous case law it would appear that entrapment claims related to online sting operations involve consideration of: a) did the law enforcement officer continuously contact the suspect with the intention of trying to convince the individual to engage in a particular type of behavior, b) how long was the relationship between the undercover officer and the suspect, and c) how much, if any, reluctance to commit the criminal act did the suspect provide evidence of? 相似文献

This study assessed the associations of characteristics of domestic violence incidents with clinically significant levels
of traumatic symptoms and behavioral problems in a socio-economically and ethnically mixed sample of 687 children participating
in a community-service program for children witnessing violence. Study predictors included child/family demographic characteristics,
type and chronicity of exposure, and child’s perceptions of control over the event and threat to personal safety. Outcomes
consisted of traumatic symptoms and behavior problems. Results showed that perceived threat and control were associated with
greater odds of clinically significant levels of several trauma symptoms (and behavior problems in the case of perceived threat)
after adjusting for effects of demographic factors and violence characteristics. Child co-victimization increased odds of
reaching clinically significant levels of traumatic symptoms compared to children who witnessed the event but were not victimized.
Female sex and White ethnicity increased odds of specific trauma symptoms and behavior problems. Increasing age reduced odds
of some trauma symptoms. Associations between predictors and one outcome measure did not generalize across the other outcome
measure. Implications of study findings, and directions for future research are discussed. 相似文献
