Allele and genotype frequencies for the 15 STR loci (FGA, vWA, MBP-L, MBP-H, HumTh01, D3S1358, D3S2406, D5S818, D7S820, D8S1179, D13S317, D18S51, D19S253, and D21S11) and two VNTR loci (D1S80 and D17S5) in a sample of unrelated Koreans were determined.  相似文献

This article examines the changing patterns of poverty in Singapore. As Singapore's population ages, the poor increasingly includes the elderly. It appears that ascribed factors, such as gender and race, have significant influence on financial security at old age. As the population ages, the adequacy of existing anti-poverty policy is challenged.  相似文献

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

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

This article interprets Joon-ho Bong’s Snowpiercer (2013) as a political allegory. First, we compare Bong’s film to Danny Boyle’s Sunshine (2007) and Christopher Nolan’s Interstellar (2014), two contemporaneous films about ecological crises. We argue that Snowpiercer exposes the limits of technocratic environmentalisms that obscure the links between ecological degradation, capitalist development, and colonial domination. Second, we put Bong’s film into conversation with autonomist Marxist and postcolonial accounts of social domination and transformation. We argue that Snowpiercer is about whether or not contemporary political economy has rendered the emancipatory strategies of recent centuries obsolete. Framed this way, the film proposes that global order is still capitalist and colonialist, but that Left projects must surpass state socialism and anti-colonial nationalism. What we call Bong’s “decolonial exodus” is the demand for a real alternative to both the ideology that there is no alternative to the existing order and the pseudo-alternative of authoritarian populism.  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
