ABSTRACT

This paper explores the livelihoods, experiences and identities of immigrant informal traders and shopkeepers in the Buffalo City Metropolitan area, which encompasses the centres of East London, Mdantsane and King Williams Town. We primarily use a socio-spatial perspective to analyse informal activity, and offer a particular perspective on how informality has encouraged a type of ‘informal citizenry’ among traders. We argue that informal trading has a very particular history in the region, and that East London’s notoriety as a ‘border city’ and a regional frontier has created a fractured space, which is best expressed through the experiences of migrants and entrepreneurs. We point out that informality is a driver of economic empowerment and equality among traders, but also of xenophobia and difference.  相似文献

A number of books and articles have been published on the relative merits of queer vs gay and lesbian, on the collisions and coalitions of queer, lesbian and feminist, on queering this and that; more has been written on the meaning of queer, its shifting semantic boundaries, its radical inclusiveness or assimilationist tactics (depending on the point of view), its role in the postmodern global market's commodification of sexuality. This paper, a contribution to social semiotics, does not contribute to the debate on queer, but continues the critical project of rethinking sexuality and gender.  相似文献

The impact of railroad development on land tenure and use in 19th‐century Mexico has long been central to interpretations of Mexico's rural history, in particular of the grievances culminating in the Revolution (1910–20). The prevailing interpretation, that railroads displaced Mexican peasants and smallholders from the land, has intuitive appeal but lacks empirical support. This article treats the question of the railroads' impact by studying the terms of the railroads' acquisition of land in southern Mexico. It argues that railroads failed to displace owners and occupants of the land, despite the governments's new laws and handpicked agents intended to oust recalcitrant residents with minimal delay and expense.  相似文献

The 15 AmpFlSTR Identifiler loci D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818 and FGA were analyzed in a sample of 378 unrelated individuals from Mexico City, Mexico. Significant deviations from HW equilibrium in 14/15 STR loci alleles were not detected. The D18S51 locus had the highest power of discrimination (0.970). Genetic admixture estimations revealed a 69% of Amerindian, 26% of European and 5% of African contribution. Comparative analyses between Mexicans and other neighboring populations reveal significant differences in genetic diversity. Our results are important for future comparative genetic studies in different Latin American ethnic groups, particularly Mexican Mestizos and Amerindians. They should also be helpful in genetics, population evolution, forensic and paternity testing.  相似文献

A five Mini-SGM multiplex which encompasses TH01, FGA, D18S51, D16S539 and D2S1338, common STR markers in human identity testing, have been performed. Two cases with different biological tissues were selected to illustrate the usefulness of this technique in forensic casework. The use of routine methodology can sometimes give only a partial genetic profile or no profile at all. However, using the Mini-STR technique, a full profile was obtained for the majority of the degraded samples. We conclude that the Mini-SGM methodology is more sensible than routine methodology for degraded samples, although a full genetic profile is not obtained in all cases as results are still very much sample-dependent. This Mini-SGM multiplex can be considered a useful tool to complement conventional STR analysis in degraded samples.  相似文献

Abstract: Improvised explosive devices (IEDs) represent one of the most common modes of arbitrarily injuring or killing human beings. Because of the heat generated by, and destruction to, an IED postconflagration, most methods for identifying who assembled the device are ineffective. In the research presented, steel pipe bombs were mock‐assembled by volunteers, and the bombs detonated under controlled conditions. The resultant shrapnel was collected and swabbed for residual cellular material. Mitochondrial DNA profiles were generated and compared blind to the pool of individuals who assembled the bombs. Assemblers were correctly identified 50% of the time, while another 19% could be placed into a group of three individuals with shared haplotypes. Only one bomb was assigned incorrectly. In some instances a contaminating profile (mixture) was also observed. Taken together, the results speak to the extreme sensitivity the methods have for identifying those who assemble IEDs, along with precautions needed when collecting and processing such evidence.  相似文献

Study questionWhen is it acceptable for a psychiatrist to break confidentiality to protect the wife of a potentially violent patient?Methods153 lay persons, 13 nursing personnel, 10 physicians, and 10 psychologists in France indicated this acceptability in 48 scenarios. The scenarios were all combinations of 5 factors: gravity of threat (death or beating), certainty of mental illness (certain or not), time spent talking with patient (considerable or little), his attitude toward psychotherapy (rejection, indecision, or acceptance), and whether the physician consulted an expert.ResultsLay people favored breaking confidentiality more than did nursing personnel or psychologists. Consulting an expert had greatest impact. Lay participants were composed of groups that found breaking confidentiality “always acceptable” (22 participants), “depending on many circumstances” (106), requiring “consultation with an expert” (31), and “never acceptable” (27).ConclusionLay people in France are influenced by situational factors when deciding if a psychiatrist should break confidentiality to protect a patient's wife.  相似文献

This article begins and ends with a call for more empirical research to understand the connection between societal views of mental illness and the legal system. The author asserts that changing social perceptions of mental illness certainly affect legal outcomes and commitment levels, but the degree remains unknown. This article explores the above two topics through the framework of the Circuit Court 'split' regarding the Constitutional rights of persons committed to state mental health institutions. A main facet of the 'split' is centered on the Circuits' disagreement about whether or not all mentally ill patients committed to institutions deserve the same Constitutional protections.  相似文献
