A case‐study is presented of two Los Angeles‐based cross‐cultural coalitions, the Black‐Korean Alliance [BKA] and the Latino‐Black Roundtable [LBR]. An analysis of the development and eventual dissolution of these two coalitions is presented against the backdrop of the history of relations between the African‐American, Korean‐American and Latino communities of Los Angeles. The central issues leading to the breakup of the two coalitions were: lack of resources, internal power dynamics between coalition partners, nationalistic factions within the broader communities, cross‐cultural dynamics between coalition members, the use of a dialogue model to frame coalition activities, and the analysis of intergroup relations underlying the formation of the coalitions. The applied and theoretical implications of the research are discussed. 相似文献

Using the National Longitudinal Survey of Freshmen (NLSF), we examine both between- and within-group differences in the odds of feeling intraracially harassed. Specifically, we investigate the effects of colleges’ and universities’ racial composition as well as the nature of students’ associations with non-group members, including involvement in racially homogeneous campus organizations, ethnoracial diversity of friendship networks, and interracial dating. Our findings suggest that although college racial composition appears to have little effect on experiencing intraracial harassment, the nature of students’ involvement with other-race students matters a great deal. For all groups, interracial dating increased odds of harassment. Among black and white students, more diverse friendship networks did as well. And among Asian and Latino students, involvement in any racially homogeneous campus organization was associated with increases in reports of intraracial harassment. Thus, we propose a baseline theoretical model of intraracial harassment that highlights the nature of students’ associations with outgroups. 相似文献

Studies on migration and integration in Britain have noted the paucity of research on ‘new’ migrants, especially ‘illegal’ migrants and asylum seekers. This paper focuses on one understudied group – Albanian immigrants and their children – and looks at their migration and settlement, based on sixty interviews conducted in two phases either side of a 2003 mini-amnesty that gave many indefinite leave to remain. This regularization is the fulcrum around which our analytical narrative is built. Focusing on the interaction of migrants' agency with host-country structure, the paper shows that an unsettled asylum policy and delays in implementation have had deleterious effects on migrants' integration and sense of belonging, even after citizenship acquisition. As they search for a social and ethnic positioning within a multi-ethnic host society, the eventual realization of Albanians' migration project is accompanied by culture shock, intergenerational difference and ambivalence towards integration. 相似文献

Multicultural society and everyday cultural racism: second generation of Ethiopian Jews in Israel's ‘crisis of modernization’ 总被引:1,自引:0,他引:1

Abstract The core of this article sets out to examine the extent to which a multicultural society can prevent cultural racism, which, like multiculturalism, is by definition based on a culture of diversity and separation. The ‘first modernity’ was organized along national lines, with a centralist state that opted to create an essentialist and uncontested national identity. Immigrants, especially those who came from ‘third world’ countries, were expected to undergo a process of assimilation, and to integrate into the dominant culture by relinquishing their particular past and tradition. Multiculturalism, which emerged historically as a criticism of that perspective, aims at creating a kaleidoscope of associations and cultural communities, which inevitably presents a challenge to the one ‘truth’ of the nation-state with the argument that this ‘truth’ favours some groups over others. Within the multicultural model, identity politics of various groups is perceived as a means to achieve recognition, acceptance, respect and even public affirmation of differences. However, do multicultural society and identity-related differences provide a solution to cultural racism as well? Investigating the second generation of the Ethiopian Jews, who migrated to Israel during its transformation from ethno-national republicanism to a neo-liberal, multicultural society, can help answer this question. By presenting their patterns of association, character of protest activities and the newly formed hybrid identity that Ethiopian youth have developed as a means to liberate themselves from a discriminating reality, and by examining the Others’ reaction to that challenge, this article uncovers certain mechanisms and methods of action through which a multicultural society, having a thin and mild version of multiculturalism, does not diminish cultural racism, particularly its everyday non-institutional version, but in fact augments it. 相似文献

This article identifies the phenomenon of ethnic civil society activism as mobilization that seeks to empower an ethnic community and challenges the institutional order. The case of the Palestinian Arab minority in Israel is discussed and is used to reveal the conditions under which disaffected minorities pursue the path of ethnic civil society. The study finds that an analytical framework that stresses the mutability of state structures and changes in broader state-society relations provides a better explanation than existing theories of ethnic conflict. State-society characteristics conducive to this type of mobilization are a well-institutionalized state that can prevent deviation from the state's foundational rules and a counterbalanced dispersion of authority that limits regime capacity to control society. 相似文献

This paper analyzes the immensely popular animated film Ratatouille as a social and cultural document. It begins with a recapitulation of the movie's story line – a saga of an astute, ambitious and talented rat, who becomes transformed into an accomplished haute cuisine chef. The film illustrates recent anthropological writings on the central role of cooking in human evolution. It also shows how varieties of cooking and table manners provide key indications of the civilizing process. Ultimately, Ratatouille explores distinctions and similarities between “man and beast”. It communicates the idea that all living creatures share more in terms of aptitude and feeling than divides them. 相似文献

Nuclear medicine physicians are very involved in French's oncology announcement procedure. However, their role needs to be analysed and evaluated. Before diagnosis’ announcement, information provided by nuclear medicine physicians are never neutral for patients. Information must not increase patient's anxiety or false patient's sense of reassurance. In this context, it seems necessary to engage in ethical reflexions about nuclear medicine physicians communication challenges. 相似文献

Abstract From the measurements of the profiles of hydraulic conductance and water potential from soil through to the leaf system in fully established melon plants, the limits to water flow set by coupling of hydraulic conductance (k) with water relation parameters was evaluated in the laboratory using high pressure flow device (HPFM) and evaporative flux method (EF). The rootstock Arava was grafted onto self, and onto two genotypes (AR57 and AR82) using side and V graft types, and there was an ungrafted control. Hydraulic transport efficiency was estimated from measurements of evaporative flux (transpiration rate) and leaf water potential (ψL) measured between pre-dawn and sunset during the growth cycle. Measured parameters to characterize the hydraulic efficiency (architecture) of the vascular system of melon were normalized to areas of leaves and stem cross section; this enabled the examination of their physiological and ecological functions. The effects of rootstock genotype were more marked on graft union and scion water relations. Differences in the magnitudes of water relation parameters of hydraulic conductance, water potential (lwp) and evaporative water loss (EF) were detected. AR/RS82 side grafted exhibited high EF and Kh despite its lower leaf water potential compared to AR/RS57 V grafted. Self grafting (Arava/Arava grafts) in melon seems to improve water relations and xylem water transport efficiency. Parameters describing the hydraulic efficiency (architecture) of vascular system of melon plants were described in relation to plant attributes. The expression of hydraulic conductance of the root and shoot system relative to plant attributes did not eliminate differences in the magnitudes of conductance elements in tomato and melon. Differences obtained among the different melon grafts in whole plant leaf and stem area specific hydraulic conductance (Kl) indicate the carbon efficiency and hence the cost of resource allocation to areas of root surface and leaves. The role of plant water relations in root-shoot communications and whole plant regulation of water flux are inferred from this study. 相似文献

A method for in situ monitoring of the isotope composition of tree xylem water using laser spectroscopy 总被引:1,自引:0,他引:1 下载免费PDF全文

Field studies analyzing the stable isotope composition of xylem water are providing important information on ecosystem water relations. However, the capacity of stable isotopes to characterize the functioning of plants in their environment has not been fully explored because of methodological constraints on the extent and resolution at which samples could be collected and analysed. Here, we introduce an in situ method offering the potential to continuously monitor the stable isotope composition of tree xylem water via its vapour phase using a commercial laser‐based isotope analyser and compact microporous probes installed into the xylem. Our technique enables efficient high‐frequency measurement with intervals of only a few minutes per sample while eliminating the need for costly and cumbersome destructive collection of plant material and laboratory‐based processing. We present field observations of xylem water hydrogen and oxygen isotope compositions obtained over several days including a labelled irrigation event and compare them against results from concurrent destructive sampling with cryogenic distillation and mass spectrometric analysis. The data demonstrate that temporal changes as well as spatial patterns of integration in xylem water isotope composition can be resolved through direct measurement. The new technique can therefore present a valuable tool to study the hydraulic architecture and water utilization of trees. 相似文献

The question of Kurdish language rights has been a central issue in the Turkish–Kurdish conflict. The current study examined endorsement of Kurdish language rights in relation to intergroup factors (i.e. group identifications, cross-group friendships, perceived discrimination, and perceived out-group beliefs about state unity) among self-identified Turkish and Kurdish participants. The results indicate that Turks were much less in favour of these rights than the Kurds. In addition, for the Turks, higher national and ethnic identification were associated with lower support for Kurdish language rights, while cross-group friendship, perceived discrimination of Kurds and the belief that Kurds endorse national unity were associated with more support for rights. For the Kurdish participants, stronger national identification seems to undermine the mobilizing meaning that Kurdish group identification has for language rights support. Furthermore, friendship with Turks can undermine the support for rights because it strengthens national identification and reduces ethnic identification. 相似文献
