Nation‐building is an age‐old process being implemented in new ways. It consists of two separate aspects: state‐building implemented by external actors and identity‐building implemented by grassroots actors within the state itself. However, a functioning state is a necessary precondition for identity‐building because it allows for the development of a civic identity that can incorporate group identities and create a shared sense of community. When a unifying and legitimate state structure is absent, group identifications will remain strong and counteract internal efforts at nation‐building. Unfortunately, the record of nation‐building when understood as both state‐ and identity‐building is relatively poor. The failure of international efforts to create stable states inhibits development of a civic identity and reinforces fragmentation. That in turn brings the longevity of the state into question by raising the possibility that dissatisfied groups will again turn to violence. Learning how to develop both aspects of nation‐building more effectively is an important challenge for international actors. 相似文献

Safety hazards are frequent in the homes of families reported for child abuse and neglect. The effectiveness of a videotape intervention with two families involved with child abuse and neglect was examined, using a replicated multiple probe design across settings. Data were collected using the Home Accident Prevention Inventory — Revised, and the Checklist for the Video-Trained Parent's Behavior. Social validation and expert validation data are also presented. 相似文献

Menstruation leave for women workers brings into the public domain of mining ongoing debates around protective legislation for women. It brings into focus the presumed tensions between gender equity and gender difference with regard to women's economic citizenship. Large-scale mining in East Kalimantan in Indonesia has offered some opportunities to poor and unskilled rural women to find formal jobs in the mines as truck and heavy equipment operators. This paper presents a case study of women in mining occupations, considers the implications of current menstruation leave provisions on the employment of women in the mines and raises serious issues related to gender equity in the workplace. The involvement of women in a non-conventional workplace such as the mine pits, providing a novel site for contestation over the rights of women workers, illuminates a less-debated area in feminist studies, especially in view of the significant ongoing changes in the Indonesian framework for industrial relations. 相似文献

Using co-citation analysis, the present study attempts to rationalize and organize the combined alliance and innovation literature in order to determine its intellectual structure (i.e. its shared attributes such as models, theories, methods, findings, and implications), as well as to gain a deeper understanding of the most important research trends. More specifically, our goals are: (1) to delineate the intellectual structure of research on alliance and innovation, as represented in the academic literature; (2) to determine the subfields that constitute the intellectual structure and the relationships, if any, between these subfields; (3) to identify contributions that play a pivotal role in bridging two or more conceptual domains of research; and finally, (4) to map the intellectual structure in a two-dimensional space in order to visualize spatial distances between intellectual themes. Implications for future studies are then drawn. 相似文献

Evaluation of Commercial Kits for Dual Extraction of DNA and RNA from Human Body Fluids, , 下载免费PDF全文

STR typing of DNA evidence can identify the donor with a high power of discrimination but cannot identify the tissue origin of a body‐fluid stain. Using RNA to attribute a crime scene stain to a particular tissue may aid in reconstruction efforts. With blood from 10 donors, four DNA and RNA coextraction kits were evaluated by measuring yields and STR and mRNA profiles. T tests indicated some significant differences in kit performance. The Zymo Research ZR‐Duet? kit performed best based on average DNA (41.4 ng) and mRNA (4.07 ng) yields and was the only kit to provide complete DNA/RNA profiles for all samples. The consistency of this kit was challenged by data from additional blood and saliva donors. Further testing is advised before a superior kit is unequivocally chosen. Stand‐alone DNA or RNA purification generally offers higher yield, but coextraction may still allow successful STR profiling and tissue source identification. 相似文献

This study explored the perceptions of young adolescents of the costs and benefits of cigarette smoking. These perceptions were examined as a function of the sex of the adolescent and peer smoking habits. The sample consisted of 155 White middle class male and female adolescents, aged 12 to 15. The results indicate that endorsement of particular costs and benefits was related to the respondent's sex and whether or not the respondent had friends who smoked. The girls seemed to view smoking as a sign of rebellion or autonomy, while the boys seemed to view smoking cigarettes as a social coping mechanism. The effect of having friends who smoke was always mediated by the sex of the adolescents. Boys who have friends who smoke have attitudes that appear more conducive to smoking than do boys with nonsmoking friends. This relationship did not hold for girls. The implications for smoking education and intervention are discussed.This work was supported in part by the Comprehensive Cancer Center of Metropolitan Detroit as supported by Grant CA - 22453 from the National Cancer Institute, DHHS. 相似文献
