Preparations for a centenary exhibition to mark the 1898 Cambridge Anthropological Expedition to the Torres Strait incorporated cross-cultural collaborative work, reflecting the changing roles of museums as sites for contact and research combining curatorial expertise and indigenous knowledge. Specific objects in the collections of the University of Cambridge Museum of Archaeology and Anthropology continue to be active intermediaries in the relationship between museum staff and Torres Strait Islanders and the museum itself has become an important field site. This paper provides an ethnography of the process of creating the exhibition and explores different ways that many of the objects displayed have resonance for Islanders today.  相似文献

Termites from the genus Odontotermes are known to contain numerous species complexes that are difficult to tell apart morphologically or with mitochondrial DNA sequences. We developed markers for one such cryptic species complex, that is, Odontotermes srinakarinensis sp. nov. from Maxwell Hill Forest Reserve (Perak, Malaysia), and characterised them using a sample of 41 termite workers from three voucher samples from the same area. We then genotyped 150 termite individuals from 23 voucher samples/colonies of this species complex from several sites in Peninsular Malaysia. We analysed their population by constructing dendograms from the proportion of shared-alleles between individuals and genetic distances between colonies; additionally, we examined the Bayesian clustering pattern of their genotype data. All methods of analysis indicated that there were two distinct clusters within our data set. After the morphologies of specimens from each cluster were reexamined, we were able to separate the two species morphologically and found that a single diagnostic character found on the mandibles of its soldiers could be used to separate the two species quite accurately. The additional species in the clade was identified as Odontotermes denticulatus after it was matched to type specimens at the NHM London and Cambridge Museum of Zoology.  相似文献

This article examines the process of ethnic identity formation among two different groups of recent immigrants to the United States: secular kibbutz‐born Israelis and middle‐class Haitians. While the two groups are different in a number of ways, they share an ambivalence with the identities that American society would assign to them ‐ as Jews and blacks respectively. By contrasting these two case studies we identify the role of the ‘proximal host’, the category to which the immigrants would be assigned following immigration. The determination of the ultimate definition of the ethnic identities of these immigrants is a result of the interaction of the conception of identity the immigrants bring with them from their countries of origin, the definitions and reactions of the proximal host group, and the overall ordering and definitions of American society. The ambivalence of both groups of immigrants towards their post‐immigration identities is a result of both macro‐forces determining the definition of categories and micro‐forces of individual choice. In conclusion we show that because of the primacy of race in American society, Israelis are likely to face many more options in the determination of their identities, than are Haitians, although they both face a similar structural dilemma.  相似文献

This article explores how Hindu activism in Britain challenges our understanding of the relationship between ethnicity and religion. It argues against the prevalent model in which Hindu identity is understood as a natural ‘product’ of ethnic identity development. Instead, this article calls for thinking about current religious activism as a response to multicultural politics, national belonging and the experience of being an ethnic minority. Based on anthropological fieldwork, the article examines the development of an organization that has successfully established Hindu societies across the UK, one that changed from initially being pro-Hindu to one that espouses Hindutva. The analysis of the rhetoric of a pro-Hindu speech reveals the aims of this group to distinguish themselves from other Asians, particularly the Muslim minority. Such examples of religious activism among “diaspora” youth require us to rethink our understandings of the connections between religion and ethnicity.  相似文献

The changing boundaries of the study of ethnicity and race have been the subject of much debate in recent years. New theoretical debates have come to the fore and empirical research has broached new questions. Taking its cue from the wide range of themes covered in this special issue, this article seeks to map out some of the key areas in which this transformation has become apparent and to highlight the implications for ethnic and race relations as a field of study. In doing so it engages with some of the key questions that run through the whole of this special issue, including the relationship between race, power and politics, identity and difference and the politics of multiculturalism. It concludes by touching on some issues that need further research and analysis.  相似文献

This article explores the contested meanings of the ‘Asian American’ concept in the US today. Since its emergence in the late 1960s, ‘Asian American’ has been defined by pan-Asian groups and organizations in the US as a collectivity bound by shared racial interests. Contemporary conditions have sharpened and highlighted the inherent contradictions and ambiguities of this conception of ‘Asian American’ as a racial interest group. Especially important have been the shifts in the composition of the Asian American population that followed the immigration reforms of 1965. Contestations of ‘Asian American’ also reflect larger uncertainties about the meaning of race in the US today, in particular, the nature of racial boundaries and racial disadvantage.  相似文献

The anticodon sequence is a major recognition element for most aminoacyl-tRNA synthetases. We investigated the in vivo effects of changing the anticodon on the aminoacylation specificity in the example of E. coli tRNAPhe. Constructing different anticodon mutants of E. coli tRNAPhe by site-directed mutagenesis, we isolated 22 anticodon mutant tRNAPhe; the anticodons corresponded to 16 amino acids and an opal stop codon. To examine whether the mutant tRNAs had changed their amino acid acceptor specificity in vivo, we tested the viability of E. coli strains containing these tRNAPhe genes in a medium which permitted tRNA induction. Fourteen mutant tRNA genes did not affect host viability. However, eight mutant tRNA genes were toxic to the host and prevented growth, presumably because the anticodon mutants led to translational errors. Many mutant tRNAs which did not affect host viability were not aminoacylated in vivo. Three mutant tRNAs containing anticodon sequences corresponding to lysine (UUU), methionine (CAU) and threonine (UGU) were charged with the amino acid corresponding to their anticodon, but not with phenylalanine. These three tRNAs and tRNAPhe are located in the same cluster in a sequence similarity dendrogram of total E. coli tRNAs. The results support the idea that such tRNAs arising from in vivo evolution are derived by anticodon change from the same ancestor tRNA.  相似文献

In recent years discussion about female genital mutilation (FGM) has expanded and the UN has recently called for a universal ban of the practice. The practice in Southeast Asia is widespread among Malay Muslims and, although different styles and practices exist, procedures conducted in medical clinics are extremely minor and, according to gynaecological research, have no effect on sexuality due to the clitoris being left totally untouched. One of the states in which Malay Muslims maintain such a tradition is Singapore. Nonetheless, Singapore is rarely mentioned in academic studies or even in reports discussing the ritual. Even inside Singapore, only Malays tend to know of the tradition, while other ethnic groups remain oblivious to the fact that Singapore is among the states that allow such an operation. The present article does not discuss FGM per se and avoids contributing to the diatribe about labels and values, although these are, of course, extremely relevant. Instead it focuses on the reasons for the practice remaining hidden and undiscussed in Singapore, so much so that some respondents did not know that they had been circumcised.  相似文献

Banana streak virus (BSV), a member of genus Badnavirus, is a causal agent of banana streak disease throughout the world. The genetic diversity of BSVs from different regions of banana plantations has previously been investigated, but there are relatively few reports of the genetic characteristic of episomal (non-integrated) BSV genomes isolated from China. Here, the complete genome, a total of 7722bp (GenBank accession number DQ092436), of an isolate of Banana streak virus (BSV) on cultivar Cavendish (BSAc...  相似文献

Several authors have studied identity by descent (IBD) by way of a continuous recombination process along a chromosome. Despite its potential uses in, for example, gene mapping or delineation of biological relationships there has been no exact algebraic result given for the probability density function of the IBD proportion in any familial relationship. Other authors have derived algebraic approximations in the case of half-sibs by way of the Poisson clumping heuristic and used computational methods to compute the distribution function of the IBD sharing for unilineal relationships. Here we provide a general numerical method for finding the density of IBD sharing that could be applied to any unilineal relationship and more importantly we derive algebraically an expression for the density for a grandparent-grandchild relationship. Initially we assume that recombination events occur at random along a chromosome, then go on to show how the method could be extended to incorporate a form of genetic interference.  相似文献
