Ethnic and sub-ethnic attachments among Chinese,Korean, and Indian immigrants in New York City

This article compares ethnic and sub-ethnic attachments in Chinese, Indian, and Korean immigrants in New York City, based on results of a survey. Indian respondents, with much higher levels of education and fluency in English, show a lower level of cultural ethnic attachment than the other two groups. The Chinese show the lowest level of formal ethnic affiliation, mainly due to their much lower level of religious affiliation. All three groups show extremely high levels of informal ethnic networks. However, Chinese and Indian respondents largely limit their close friendships to their sub-ethnic group, based on national origin, religion, regional origin and/or language, while Korean respondents, characterized by group homogeneity, tend to maintain close friendships with all other Koreans. Much larger proportions of Chinese and Indian respondents than Koreans choose the sub-ethnic identity label and they show much lower levels of loyalty to their homeland than Korean respondents.     

Racialized national identity construction in the ancestral homeland: Japanese American migrants in Japan

This article examines Japanese Americans in Japan to illuminate how ‘Japanese American’ – an ethnic minority identity in the US – is reconstructed in Japan as a racialized national identity. Based on fifty interviews with American citizens of Japanese ancestry conducted between 2004 and 2007, I demonstrate how interactions with Japanese in Japan shape Japanese Americans’ racial and national understandings of themselves. After laying out a theoretical framework for understanding the shifting intersection of race, ethnicity, and nationality, I explore the interactive process of racial categorization and ethnic identity assertion for Japanese American transnationals in Japan. This process leads to what I call racialized national identities – the intersection of racial and national identities in an international context – and suggests that US racial minority identities are constructed not only within the US, but abroad as well.     

Violence and trauma as constitutive elements in Korean American racial identity formation: the 1992 L.A. riots/insurrection/saigu

This paper proposes a new understanding of race as an artifact constructed from racist violence and the trauma it engenders. The paper applies Jeffrey Alexander's concept of ‘cultural trauma’, i.e. when ‘members of a collectivity feel they have been subjected to a horrendous event that leaves indelible marks on their group consciousness’, to the case of Korean immigrant merchants who were victims of violence during the 1992 L.A. riots/insurrection/saigu in Los Angeles, California, following the acquittal of four white police officers charged with violently assaulting a black motorist. Though the violence was contained to distinct neighbourhoods, the larger society experienced the terror because of the mass media. Over time this media-event led to the construction of a new identity rooted in violence and trauma. Through an examination of various texts, this paper argues that the Korean-American collective consciousness shifted discursively from an identity rooted in nationality to one incorporating race.     

Bridging the gap: transnational and ethnic organizations in the political incorporation of immigrants in the United States

This study was prompted by concerns about the ways in which immigrant organizations, especially those of a transnational character, may retard or prevent political integration among recent migrants to the United States. For this purpose, we constructed an inventory of all organizations created by Colombian, Dominican and Mexican immigrants in the United States, interviewed leaders of the twenty largest organizations from each group in person, and conducted a survey of 178 additional organizations by telephone or Internet. Results reveal a near-absence of perceived conflict between transnational activism and political incorporation. Almost without exception, leaders asserted that there was no contradiction between home-country loyalties and activities and US citizenship and voting. These results appear to reflect genuine conviction, rather than any social desirability syndrome. Objective indicators show that most organizations maintain close ties with US political authorities at various levels and engage in a number of US-focused civic and political activities. Determinants of such engagement are examined. Implications of the results for theory and public policy are discussed.     

Auspicious birth dates among Chinese in California

The number eight is considered lucky in Chinese culture, e.g. the Beijing Olympics began at 8:08 pm on 8/8/2008. Given the potential for discretion in selecting particular dates of labor induction or scheduled Cesarean section (C-section), we consider whether Chinese-American births in California occur disproportionately on the 8th, 18th, or 28th day of the month. We find 2.3% “too many” Chinese births on these auspicious birth dates, whereas Whites show no corresponding increase. The increase in Chinese births is driven by higher parity C-sections: the number of repeat C-sections is 6% “too high” on auspicious birth dates. Sons born to Chinese parents account for the entire increase; daughter deliveries do not seem to be timed to achieve “lucky” birth dates. We also find avoidance of repeat C-section deliveries on the 4th, 14th, and 24th of the month, considered unlucky in Chinese culture. Finally, we replicate earlier work finding that Friday the 13th delivery dates are avoided and document a particularly large decrease among Chinese. For Whites and Chinese in California, mothers with higher levels of education are particularly likely to avoid delivering on the 13th.     

Disparities in the risk of the ER/PR/HER2 breast cancer subtypes among Asian Americans in California

BackgroundPopulation-based studies of breast cancer often aggregate all Asians into a single category termed Asian/Pacific Islander (API).Purpose(1) Describe the demographic and clinicopathologic features of early breast cancer utilizing all eight ER/PR/HER2 subtypes among white, black, Hispanic, American Indian, seven Asian ethnicities, and the aggregate API category; (2) ascertain the risk of the ER+/PR+/HER2+, ER−/PR−/HER2−, and ER−/PR−/HER2+ subtypes when compared with the ER+/PR+/HER2− subtype, among seven Asian ethnicities versus non-Hispanic white women and (3) contrast the results with the risk of these same subtypes when using the aggregate API category.MethodsUsing the California Cancer Registry, we identified 225,441 cases of stages 1–4 first primary female invasive breast cancer. Logistic regression was used to assess the association of race with the ER+/PR+/HER2+, ER−/PR−/HER2− (triple-negative), and the ER−/PR−/HER2+ subtypes versus the ER+/PR+/HER2− when adjusted for stage, age, tumor grade, and socioeconomic status. Models were fit separately for each subtype. Odds ratios for the seven Asian ethnicities and the aggregate API category using non-Hispanic white women as the reference category were computed.ResultsThere was an increased risk of the ER+/PR+/HER2+ subtype for the combined API category (OR = 1.16; 95% CI = 1.09–1.23). But only Southeast Asians (OR = 1.17; 95% CI = 1.04–1.31), Filipino (OR = 1.23; 95% CI = 1.12–1.36), and Korean (OR = 1.63; 95% CI = 1.38–1.99) women had an increased risk of this subtype. The reduced risk of the triple-negative subtype seen in APIs (OR = 0.84; 95% CI = 0.79–0.90) was only noted in Chinese (OR = 0.80; 95% CI = 0.70–0.91) and Filipino (OR = 0.65; 95% CI = 0.58–0.73) women whereas Indian Continent (OR = 1.25; 95% CI = 1.01–1.53) women had an increased risk of the triple-negative subtype.The race × stage interaction was statistically significant for the ER−/PR−/HER2+ subtype (p < 0.05). When stratified by stage, there was no statistically significant association of race with subtype in stages 3 and 4. APIs had an increased risk of the ER−/PR−/HER2+ subtype in stage 1 (OR = 1.59; 95% CI = 1.37–1.75) and stage 2 (OR = 1.42; 95% CI = 1.28–1.58) but this risk was not seen in Pacific Islander, Indian Continent, and Japanese women for either stage.ConclusionsAmong the Asian ethnicities, there is marked variability in the demographic and clinicopathologic features of breast cancer. Use of the ER/PR/HER2 subtypes reveals that the risk of the ER−/PR−/HER2−, ER+/PR+/HER2+, and ER−/PR−/HER2+ subtypes varies among the Asian population. The API category, is sometimes, but not always reflective of all Asian women.     

Movement in spaces of liminality: Chinese dance and immigrant identities

This paper explores the roles of immigrant dance in ethnic construction. It is based on participant observation and in-depth interviews with a Chinese dance organization in the US Midwest. Chinese dance in the US, a transnational cultural practice, solidifies a sense of belonging among Chinese immigrants. As these immigrants make sense of what it means to be Chinese and to do Chinese dance in contemporary American society, they reinvent their collective identity while holding on to primordial understandings of ethnicity rooted in the constructed ideas of ancestry and homeland. A case study of the ethnic construction theory, this research sheds light on the paradox of embodied immigrant identities: they are constructed through cultural practices and yet often understood as primordial, transnational and yet necessarily place-bound.     

Bringing class back in: class consciousness and solidarity among Chinese migrant workers in Italy and the UK

The growing literature on international migration has a tendency to emphasize homogenous elements such as shared ethnic background, social network and cultural similarities in shaping immigrants' identity. We argue that this underestimates the differences (and sometimes conflicts) of interests between ethnic employers and migrant workers and that class needs to be brought back into the studies of ethnic relationship. Based upon findings from a series of fieldwork in Veneto, Italy and East Midlands, UK, this article contends that class consciousness has co-existed, sometimes uneasily, alongside co-ethnic and cultural relationships among Chinese migrant workers and has played an important part in the making of new Chinese communities. By analysing the perspectives of Chinese migrant workers and their relationship with co-ethnic entrepreneurs, this article illustrates complex factors behind the formation, diffusion and development of class consciousness among Chinese migrant workers.     

Growing old in a transnational social field: belonging,mobility and identity among Italian migrants

This article focuses on ageing in transnationalism. Drawing on the experiences of Italians in the UK as a paradigmatic example of settled European migrants, it explores the lived experiences of this group of older migrants. Using Levitt and Glick Schiller's framework, it concentrates first on migrants' ways of being and then on their ways of belonging. The article argues that a transnational lens is necessary to understand the experiences of older migrants and that a focus on older people needs to be incorporated into studies of transnationalism. Through a discussion of their narratives and experiences, the article offers a long view on the migration process and brings attention to the significance of gender, time and the life course to understand both migrants' transnationalism and their integration.     

A family affair: how and why second-generation Filipino-Americans engage in transnational social and economic connections

In this article, I argue that second-generation migrants can engage in cross-border ties as a result of first-generation migrants mediating relationships between their children and those abroad. This paper draws on interviews with second-generation Filipino-Americans to demonstrate how and why respondents engage in mediated social and economic cross-border ties collectively with first-generation migrant parents. Second-generation Filipino-Americans feel an obligation, not necessarily to those in the Philippines, but to parents who request that their children engage in transnational social and economic ties. Just as parents serve as the means and reasoning for why these transnational connections persist among their children, parents play a role in why ties fail to manifest. By looking into why some engage in social and economic cross-border ties while others do not, I provide insight into how the children of migrants participate in the transnational social field.     

Ethnic Variation in the Thymidylate Synthase Enhancer Region Polymorphism among Caucasian and Asian Populations

Thymidylate synthase (TS) regulates the production of DNA synthesis precursors and is an important target of cancer chemotherapy. A tandem repeat sequence in a TS promoter enhancer region (TSER) was recently identified. Polymorphic variation affected in vitro expression levels of the gene. We evaluated the influence of ethnicity on TSER genotype. Allele frequency was similar in Caucasian and Southwest Asian subjects. However, homozygous triple repeat subjects were twice as common in Chinese subjects (67%) than in Caucasian subjects (38%). This demonstrates significant ethnic variation in a TS gene regulatory element which may have significant impact on pyrimidine homeostasis and drug therapy.     

Diaspora identification and long-distance nationalism among Tamil migrants of diverse state origins in the UK

Accounts of Tamil long-distance nationalism have focused on Sri Lankan Tamil migrants. But the UK is also home to Tamils of non-Sri Lankan state origins. While these migrants may be nominally incorporated into a ‘Tamil diaspora’, they are seldom present in scholarly accounts. Framed by Werbner's (2002) conception of diasporas as ‘aesthetic’ and ‘moral’ communities, this article explores whether engagement with a Tamil diaspora and long-distance nationalism is expressed by Tamil migrants of diverse state origins. While migrants identify with an aesthetic community, ‘membership’ of the moral community is contested between those who hold direct experience of suffering as central to belonging, and those who imagine the boundaries of belonging more fluidly – based upon primordial understandings of essential ethnicity and a narrative of Tamil ‘victimhood’ that incorporates experiences of being Tamil in Sri Lanka, India and in other sites, despite obvious differences in these experiences.     

Ethnic minority identity and movement politics: The case of the Roma in the Czech Republic and Slovakia

The level of political mobilization among ethnic minorities in Central and Eastern Europe has often been regarded as directly dependent on the strong or weak ethnic identity of the groups involved. Less attention has gone to the role of ethnic leaders in creating ethnic group identities for political purposes. This article explores the influence of political mobilization on ethnic group formation in the case of the Roma (Gypsies) in the contemporary Czech and Slovak Republics. It examines the various ways in which Romani activists in these two countries have “framed” Romani identity. The article suggests that activists’ conceptions of Romani identity are closely tied to their political strategies. At the same time, Romani activists have not been able to gain complete control over the production of Romani identity. They have had to deal with powerful schemes of ethnic categorization promulgated by the media, public officials and policy documents.     

Multilevel Factors Influencing Hepatitis B Screening and Vaccination among Vietnamese Americans in Atlanta,Georgia

Chronic hepatitis B virus (HBV) infection may lead to liver cirrhosis, chronic liver disease, and liver cancer. Immunization rates are suboptimal among Asian Americans/Pacific Islanders (AAPIs), who remain disproportionately affected by these illnesses. We investigated socioecological factors affecting HBV prevention among 316 Vietnamese Americans in Atlanta, Georgia. Social and community support of HBV vaccination was associated with screening (OR=1.69, 95% CI [1.21,2.38]), vaccination (OR=1.89, [1.27,2.81]), and intent to vaccinate (OR=1.77, [1.13,2.78]). Misconceptions decreased screening likelihood (OR=0.67, [0.46,0.99]) and vaccination (OR=0.55, [0.35,0.86]). Those able to pay for medical treatment (OR=1.23, [1.01,1.50]) were also more likely immunized, and greater transportation access (OR=1.42, [1.07,1.87]) was associated with greater intention to vaccinate. Multi-level factors facilitated HBV vaccination in this population. Tailored, culturally appropriate communication strategies will positively influence immunization uptake.

Genetic,acclimatizational and anthropometric factors in hand cooling among North and South Chinese

The left hands of unacclimatized North Chinese (N = 16) and South Chinese (N = 13) were exposed to 5°C water for 30 minutes followed by a 10 minute recovery period. Significant differences independent of body composition were found between the two samples on mean 30 minute temperature during immersion, time and temperature of the onset of initial CIVD (cold-induced vasodilation) at 0.01, 0.05 and 0.10 levels respectively. The result suggests the presence of a genetic component in the cold responses of Continental Asian populations and the possibility of the presence of a clinal distribution of cold response in Asia.
