While racialized youth are often central in debates on citizenship, multiculturalism and belonging, those ascribed as ‘British Chinese’ are constructed as model minorities, lacking a hybridized culture but insulated from racism, and thus invisible in these discussions. This article argues, however, that the model minority discourse is itself a specific form of contemporary racialization that revives ‘yellow peril’ discourses on the capacities of particular ‘Oriental’ bodies. Drawing on ethnographic fieldwork, it examines how young people challenge these constructions, by drawing on popular culture to organize and participate in what they call ‘British Chinese’ and, more provocatively, ‘Oriental’ nightlife spaces. It analyses how through these spaces participants forge a sense of identity that allows them to reimagine themselves as racialized subjects. It demonstrates how these spaces constitute transient sites of experimental belonging, facilitating new cultural politics and social identifications that at once contest reified conceptions of British Chineseness yet also create new exclusions.  相似文献

A number of finite element analyses (FEAs) for the dental implant were performed without regard for preload and with all interfaces ‘fixed-bonded’. The purpose of this study was comparing the stress distributions between the conventional FEA model with all contacting interfaces ‘fixed-bonded’ (bonded model) and the model with the interfaces of the components in ‘contact’ with friction simulated as a preloaded implant (contact model). We further verified the accuracy of the result of the FEA using model experiment. In the contact model, the stress was more widely distributed than in the bonded model. From the model study, the preload induced by screw tightening generated strain at the peri-implant bone, even before the application of external force. As a result, the bonded model could not reproduce the mechanical phenomena, whereas the contact model is considered to be appropriate for analysing mechanical problems.  相似文献

While ‘ethnicity and everyday life’ is a familiar collocation, sociologists concerned with racism and ethnicity have not engaged very much with the extensive body of social theory that takes the ‘everyday’ as its central problematic. In this essay, I consider some of the ways in which the sociology of the everyday might be of use to those concerned with investigating ethnicity and racism. For its part, however, the sociology of the everyday has tended to be remarkably blind to the role played by racism and racialization in the modern world. It is thus no less crucial to consider how the experiences of racialized groups might help us rethink influential accounts of the everyday. To this end, I provide a discussion of pioneering texts by C. L. R. James and W. E. B. du Bois, both of whom were driven by their reflections on racism and resistance to recognize the everyday not as an unremarked context, but as, precisely, a problematic one.  相似文献

This article critically analyzes the arguments of the ‘generalized Darwinism’ recently proposed for the analysis of social-economical systems. We argue that ‘generalized Darwinism’ is both restrictive and empty. It is restrictive because it excludes alternative (non-selectionist) evolutionary mechanisms such as orthogenesis, saltationism and mutationism without any examination of their suitability for modeling socio-economic processes and ignoring their important roles in the development of contemporary evolutionary theory. It is empty, because it reduces Darwinism to an abstract triple-principle scheme (variation, selection and inheritance) thus ignoring the actual structure of Darwinism as a complex and dynamic theoretical structure inseparable from a very detailed system of theoretical constraints. Arguing against ‘generalised Darwinism’ we present our vision of the history of evolutionary biology with the help of the ‘hourglass model’ reflecting the internal dynamic of competing theories of evolution.  相似文献

It has been suggested that numerosity is an elementary quality of perception, similar to colour. If so (and despite considerable investigation), its mechanism remains unknown. Here, we show that observers require on average a massive difference of approximately 40% to detect a change in the number of objects that vary irrelevantly in blur, contrast and spatial separation, and that some naive observers require even more than this. We suggest that relative numerosity is a type of texture discrimination and that a simple model computing the contrast energy at fine spatial scales in the image can perform at least as well as human observers. Like some human observers, this mechanism finds it harder to discriminate relative numerosity in two patterns with different degrees of blur, but it still outpaces the human. We propose energy discrimination as a benchmark model against which more complex models and new data can be tested.  相似文献

Over the past two decades, writings generalizing about the place of Aborigines in Australia at the national level and proposing policies have been dominated by what I will call the ‘self-determination’ approach. This approach has made little theoretical or substantive contribution at the level at which moral judgement and policy have been directed because moral and political concerns have constrained and biased inquiry. This paper offers a critique of the self-determination approach by focusing on the works of Professor Tatz, who has been a major influence in its development and proselytization.  相似文献

In 1961 the green sulfur bacterium-containing mixed culture known asChloropseudomonas ethylicum was brought to Brookhaven National Laboratory (USA) from Moscow State University (USSR). The water-soluble bacteriochlorophylla-protein (FMO-protein) was extracted, purified and characterized by absorption and circular dichroism spectroscopy, by X-ray crystallography and by primary structure determination.  相似文献

Robin Nunn has argued that we should stop using the terms ‘placebo’ and ‘placebo effect’. I argue in support of Nunn’s position by considering the logic of why we perform placebo comparisons. Like all comparisons, placebo comparison is just a case of comparing one thing with another, but it is a mistake, I argue, to think of placebo comparison as a case where something is compared to ‘a placebo’. Rather, placebo comparison should be understood as a situation which sets-up the treatment and control groups in a particular way; not as a case involving objects or procedures called ‘placebos’ employed in order to control for ‘placebo effects’.  相似文献

We report on two sets of experiments designed to clarify the roles of sensory ‘confusion’ and prey ‘oddity’ as they interact to influence the hunting success of a pursuit predator, the largemouth bass (Micropterus salmoides), on silvery minnows (Hybognathus nuchalis). Bass quickly captured solitary minnows, but performed many unsuccessful attacks and took much longer to make a capture as prey school size was increased. At school sizes of eight and above, bass were effectively stymied, demonstrating the ‘confusion effect’. The inclusion of one or two ‘odd’ (blue-dyed) minnows in a school of eight greatly increased the ability of bass to capture both normal and odd prey, but this effect of oddity disappeared at a school size of 15. The implications of these results for understanding the adaptive basis of mixed species flocks, herds and schools is discussed.  相似文献

We present ataxonomic revision of the ‘manna lichens’ based on morphological, chemical, ecological and molecular data. A large number of herbarium specimens and fresh collections were examined. Phylogenetic analyses were performed using nuclear ribosomal (nrITS, nrLSU) and mitochondrial small subunit (mtSSU) sequences. Some notable phenotypic characters were plotted on the phylogenetic tree, and the analysis reveals that some of these characters are useful for genus and species level distinction of certain ‘manna lichens.’ Phylogeny of the Megasporaceae was revised using a combined data set of nrLSU and mtSSU and performing parsimony and Bayesian analyses. Five genera (Aspicilia, Circinaria, Lobothallia, Megaspora and Sagedia) are recognized. Further, the relationships of five presumably closely related genera of ‘manna lichens’, namely Agrestia (vagrant), Aspicilia (crustose) Circinaria (crustose), Chlorangium (vagrant) and Sphaerothallia (vagrant) with different growth forms were analysed. The analyses revealed that ‘manna lichens’ do not form a monophyletic group but occur in different clades within the genus Circinaria. The genera Agrestia, Chlorangium and Sphaerothallia are assigned as new synonyms under the genus Circinaria and no vagrant or erratic species remain in the genus Aspicilia. The analyses also show that five new erratic, vagrant and crustose species can be recognized. In this study two ‘manna lichens’, viz. Circinaria rostamii sp. nov. (Azerbaijan, Iran and Turkey), and Circinaria gyrosa sp. nov. (Armenia, Azerbaijan, Iran, Turkey, Turkmenistan and Spain) are described as new to science. Three potentially new species with crustose and erratic forms need additional study. Aspicilia fruticolosofoliacea is reduced to synonymy under C. alpicola, and a lectotype is designated for C. aspera. Thirteen new combinations in Circinaria are presented. The phenomenon of vagrancy is briefly discussed, and the biogeography of the ‘manna lichens’ is outlined. Illustrations, distribution maps, and an identification key to the species are provided.  相似文献

This article analyses the co-occurrence of two concerns often expressed by indigenous leaders involved with reparations for victims of paramilitaries in Colombia. These concerns revolve around discomfort with the intense use of hegemonic ‘gender’ discourses in the context of the reparations, and a feeling that leaders' involvement in the latter brings about a betrayal of the family and of themselves. By engaging with the local category of eirruku (flesh), I argue that ways of engaging women in reparations entail the commoditisation of caring relationships. This article, based on 13 months of fieldwork with an indigenous organisation and the communities integrated into it between 2007 and 2008, contributes to the understanding of the articulation of gender and ethnic/racial identification in the context of contemporary forms of governance of indigenous peoples, while delving into ‘carnality’ as a concept to understand gendered forms of reproduction, reparation and selfhood.  相似文献

Caribbean diaspora intellectuals have contributed significantly to African-American political struggles over the years, despite arguments by some African-American intellectuals about what they discern as West Indian negativism, extremism, and divisiveness in American political life. This essay examines the legacy of a representative sample of diasporic Caribbean intellectuals since the time of the Harlem Renaissance in the 1920s and culminating in the 1970s, notably, Garvey, members of the African Blood Brotherhood [ABB], C.L.R. James, and Walter Rodney, to demonstrate the phenomenal ideological vision, organizational capability, and political activism they have brought into fostering solidarity with African Americans in the struggle for fundamental change. The focus here is on their respective contributions to the debate on the relationship between class and race in America and the black diaspora generally, which has helped to shape the form, and orient the direction of African-American and Caribbean diasporic struggles for the better part of the twentieth century.  相似文献

This paper is concerned with a Filipino psychic surgeon confronted by a particularly challenging case of a kind perhaps unprecedented in his practice. The paper describes and analyzes how the practitioner modified his usual clinical performance and adapted his actions to demands of an extremely difficult situation. The case is viewed in wider perspective relative to the significance of performative acts of healing in a pluralistic medical setting.  相似文献

During the past decade the relationship between biodiversity and human diversity has received increased attention, resulting in the identification of what the Declaration of Belém calls an ‘inextricable link’ between biological and cultural diversity. Although the term biocultural diversity, introduced to denote this link, is being used increasingly, there has been little critical reflection on what it precisely refers to. I argue that it is used with particular reference to ‘indigenous traditional’ people, but that there is scope for extending its application within biocultural discourse. I therefore review the concept of culture and discuss what constitutes cultural values of the natural environment. I conclude that the concept of culture must be understood as involving a dynamic process of transcultural exchange and constant re-articulations of tradition resulting in the persistence of certain cultural practices. This approach ultimately reveals that the concept of biocultural diversity is also applicable to non-indigenous traditional communities.  相似文献

Focusing on ethnic Chinese as cultural citizens of the nation, this paper examines national identity in the context of generational change. In so doing, it connects to colonialist conceptions of identity the dominant framework of ethnicity that operates in Malaysia. It argues that this framework allows for the nationalist imagining of ‘Malaysian-Chinese’ as ‘outsiders’. In probing the complex conceptual relationship between ethnicity, national identity and cultural citizenship, this article asks: How does ‘ethnicity’ enter into negotiations over the ‘national’ in the cultural realm? What are the notions of cultural difference and national otherness that operate in the negative dualisms by which nation and ethnicity are defined? How are these dualisms tied to notions of authenticity and cultural citizenship? Using the novel The Harmony Silk Factory by Malaysian author Tash Aw to address these questions, this paper argues the need to rethink current policies and narratives of ethnic and national identity in Malaysia.  相似文献

This study provides a critical historical review and analysis of the variety of human expressions which have been erroneously labeled under the grandiose category mass hysteria. It is argued that Western science reductionist approaches to the classification of mass hysteria treat it as an entity to be discovered transculturally, and in their self-fulfilling search for universals systematically exclude what does not fit within the autonomous parameters of its Western-biased culture model, exemplifying what Kleinman (1977) terms a category fallacy. As a result of objectivist methodologies, the etiology of actions labeled as mass hysteria is typically viewed as deviant, irrational or abnormal behavior resulting from a malfunctioning proper social order. However, what constitutes the correct social order is a function of a researcher's historical sociocultural and/or scientific milieu. This study reviews the problem, advocating Geertz's (1973) culturally relativistic approach to understanding various cross-cultural behavior that is sensitive to and tolerant of the unique context and milieu of participants. Mass or epidemic hysteria is viewed as an invention of Western psychiatry and should be abandoned and replaced with the term collective exaggerated emotions. Instead of attempting to discover a neatly packaged, unitary external disease entity, the focus of a meaning-oriented approach emphasizes the deciphering of foreign realities, semantic networks and symbol systems.  相似文献
