Rapid urbanization is among the major processes affecting the developing world. The influx of migrants to cities frequently provokes antagonism on the part of long‐term residents, manifested in labor market discrimination, political nativism, and violence. We implemented a novel, face‐to‐face survey experiment on a representative sample of Mumbai's population to elucidate the causes of anti‐migrant hostility. Our findings point to the centrality of material self‐interest in the formation of native attitudes. Dominant group members fail to heed migrants' ethnic attributes, yet for minority group respondents, considerations of ethnicity and economic threat crosscut. We introduce a new political mechanism to explain this divergence. Minority communities facing persistent discrimination view in‐migration by coethnics as a means of enlarging their demographic and electoral base, thereby achieving “safety in numbers.” Our article sheds light on the drivers of preferences over internal migration. It also contributes insights to the international immigration literature and to policy debates over urban expansion. 相似文献

There are a number of forensic cases in which the identification of the epithelial cell type from which DNA originated would provide important probative evidence. This study aimed to develop a technique using histological staining of fixed cells to distinguish between skin, buccal and vaginal epithelium. First, 11 different stains were screened on formalin-fixed, wax-embedded cells from five women. Samples were analysed qualitatively by examining staining patterns (colour) and morphology (absence or presence of nuclei). Three of the staining methods – Dane's, Csaba's and Ayoub-Shklar – were successful in distinguishing skin epithelial cells from buccal and vaginal. Second, cells were smeared directly onto slides, fixed with one of five fixatives and stained with one of the three stains mentioned above. Methanol fixation, coupled with the Dane's staining method, specific to keratin, was the only technique that distinguished between all three cell types. Skin cells stained magenta, red and orange and lacked nuclei; buccal cells stained predominantly orange–pink with red nuclei; while vaginal cells stained bright orange with orange nuclei and a blue extracellular hue. This staining pattern in vaginal cells was consistent in samples collected from 50 women aged between 18 and 67. Identification of cell type from unlabelled micrographs by 10 trained observers showed a mean success rate of 95%. The results of this study demonstrate that histological staining may provide forensic scientists with a technique for distinguishing between skin, buccal and vaginal epithelial cells and thus would enable more conclusive analyses when investigating sexual assault cases. 相似文献

The policyholder's “duty to cooperate” is built into every liability insurance policy, either expressly or through the application of a state's common law. The scope of an insured's duty to cooperate is often difficult to discern, however, in terms of the type and extent of information that the insured should provide as part of the insurer's investigation of the underlying matter for which coverage is being sought. Traditionally, the duty to cooperate was intended to encourage information sharing to allow the insurer to afford the policyholder a comprehensive, informed defense to the underlying claimant's allegations. This article examines the scope of the duty to cooperate and how that duty impacts the insured's obligation to share some reasonable amount of information as part of the insurer's investigation and defense of the underlying claim, noting potential pitfalls and risks that may arise from information sharing. 相似文献
