Most scholarship on citizenship focuses on institutional and structural analyses and extrapolates these to individual citizens' experiences. This renders citizenship a static and uniform concept that is divorced from individuals' understandings. Data gathered during qualitative and ethnographic fieldwork in Berlin, Germany, in 2000–01 show how ordinary Germans' understandings of citizenship challenge an oversimplified narrative about “Germanness” which has assigned a static notion of German citizenship as based on “blood”, or principles of jus sanguinis. By analyzing interviews with 60 working-class youth, this article demonstrates that these young people construct understandings of citizenship based primarily on cultural criteria. These findings redefine prevailing assumptions about Germans' understandings of citizenship and demonstrate that citizenship and naturalization policies cannot be used as a measure of the meaning of citizenship for ordinary citizens. Citizenship is not a static or uniform concept, but is rather imagined and re-imagined by ordinary citizens in a variety of ways.  相似文献

Political debates over the concept of “fetal rights” pose in sharp relief questions regarding the meaning of biological gender difference for gender equality. Can the state's obligation to “protect” fetal health be used to modify or control women's behavior? If so, what does this mean for women's status as full and equal citizens in a democratic society? This article addresses these questions through an analysis of the political, legal, scientific and moral debates over “fetal protection policies” in hazardous workplaces.  相似文献

The effects of maternal age and the social context on the home environment, and maternal behaviors of adolescent and older mothers, as well as the stability of the care-giving environment, were studied. Fifty low-middle socioeconomic status (SES), primiparous, Caucasian mothers and their fullterm healthy infants were included. At four months, support systems and life stress were assessed, as well as the home environment and maternal behaviors. At two years, a similar home visit was conducted in a subsample. Adolescent mothers had less education, lower SES, and a different child care support system. They also differed in the home environment and maternal behaviors at four months. Some of these differences disappeared when maternal education and SES, or child care support and life stress, were controlled. Moderate correlations were observed between four months and two years home environment and maternal verbalizations. Thus, a combination of maternal age and other social factors mediate the negative characteristics of the adolescent mother's care-giving environment, which is relatively stable during the infancy period.Received Ph.

The present study examined the mechanisms by which social competence may be associated with substance use during early adolescence. The sample consisted of rural youth (N = 1,568) attending 36 junior high schools in a midwestern state. Structural equation modeling indicated that social competence had a direct protective association with substance use in that those youth who were more socially confident, assertive, and had better communication skills reported less smoking and drinking. Further analyses revealed that the relationship between social competence and substance use was fully mediated by social benefit expectancies of use. These findings suggest that poorly competent youth turn to smoking and alcohol use because they perceive that there are important social benefits to doing so, such as having more friends, looking grown up and cool, and having more fun. Prevention programs that teach youth interpersonal skills may reduce the initiation of substance use by improving social competence and providing youth with more adaptive means of gaining approval from peers.  相似文献

Multiplex DNA typing methods using massively parallel sequencing can be used to predict externally visible characteristics (EVCs) in forensic DNA phenotyping through the analysis of single-nucleotide polymorphisms. The focus of EVC determination has focused on hair color, eye color, and skin tone as well as visible biogeographical ancestry features. In this study, we researched off-label applications beyond what is currently marketed by the manufacturer of the Verogen ForenSeq kit primer set B and Imagen primer set E SNP loci. We investigated additional EVC predictions by examining published genome wide sequencing studies and reported allele-specific gene expression and predictive values. We have identified 15 SNPs included in the ForenSeq kit panel and Imagen kits that have additional EVC prediction capabilities beyond what is published in the Verogen manuals. The additional EVCs that can be predicted include hair graying, ephelides hyperpigmented spots, dermatoheliosis, facial pigmented spots, standing height, pattern balding, helix-rolling ear morphology, hair shape, hair thickness, facial morphology, eyebrow thickness, sarcoidosis, obesity, vitiligo, and tanning propensity. The loci can be used to augment and refine phenotype predictions with software such as MetaHuman for missing persons, cold case, and historic case investigations.  相似文献

Women are forbidden from giving birth within the community in Dove, Ghana because it is against their culture. Such cultural practice is scarce in contemporary societies so studies on the impact of the practice are currently limited in development literature. This article uses key informant interviews and focus group discussion guides to gather data. Findings reveal that the Chief, the Queenmother, and other community members maintain that the practice is not negatively affecting the socio-economic development of Dove as they have strategies to mitigate the practice.  相似文献

The information inherent in cigarette ash in the form of trace‐metal concentrations may be of use in a forensic context as it can indicate the brand from which the ash originated. This knowledge might help place suspects at crime scenes or determine how many people may have been present. To develop and test statistical models capable of classifying ash samples according to brand, commercial cigarettes procured in the U.S. and overseas were “smoked” using a peristaltic pump, mimicking the range of human smoking habits. Ash samples were digested in a mixture of nitric and hydrochloric acid applying microwave digestion and analyzed using inductively coupled plasma‐mass spectrometry. Principal component analysis of the elemental data showed intrinsic differences between brands. Partial least squares‐discriminant analysis demonstrated that brand classification yields good sensitivity and specificity for a number of models tested. Varying smoking parameters did not impact the classification of ash samples.  相似文献
