Ethnoreligious change in Northern Ireland and Zimbabwe:A comparative study of how religious havens can have ethnic significance

This study compares the internal dynamics of religious change in the 'post-evangelical' Ikon community in Belfast, Northern Ireland, and a charismatic, multiethnic congregation in Harare, Zimbabwe. Although the theological ideas behind Ikon and the congregation vary widely, the processes whereby both groups manage change are broadly similar and have wider theoretical significance. Accordingly, this article analyses how people use the religious resources of their traditions to construct 'havens' in which change is facilitated. Havens are conceived of as safe spaces where people use religious resources to challenge ethnic boundaries and power structures. They can be seen to function as mechanisms for disrupting long-entrenched feedback patterns of opposition and conflict. © 2010 The Editor of Ethnopolitics.

Brand personification and symbolic consumption among ethnic minority teenage consumers: An empirical study

A plethora of evidence suggests that developed societies such as the United Kingdom are becoming increasingly multicultural by the day. Hence, the diversity of consumption in these societies becomes gradually evident in the form of residents’ age, gender, income and ethnicity. Accordingly, this article explores the brand personification and symbolic consumption in respect of London-based Black African teenage consumers. The study is rooted in the interpretive research paradigm with 36 in-depth interviews conducted with the target respondents. The study shows the interactions of personal, social, cultural, psychological and commercial factors in how these young ethnic minority consumers make their consumption decisions, define and manage their various ‘selves’ in the postmodern society. It specifically highlights that they use symbolic consumption to address their need for acceptance in the society. It updates the extant ethnic minority studies and enriches the current understanding about symbolic consumption and brand personification especially with a focus on a specific segment of the society. The managerial implications of the study are highlighted in the article.

Menarche, menopause, and breast cancer risk: individual participant meta-analysis, including 118 964 women with breast cancer from 117 epidemiological studies.

BACKGROUND: Menarche and menopause mark the onset and cessation, respectively, of ovarian activity associated with reproduction, and affect breast cancer risk. Our aim was to assess the strengths of their effects and determine whether they depend on characteristics of the tumours or the affected women. METHODS: Individual data from 117 epidemiological studies, including 118 964 women with invasive breast cancer and 306 091 without the disease, none of whom had used menopausal hormone therapy, were included in the analyses. We calculated adjusted relative risks (RRs) associated with menarche and menopause for breast cancer overall, and by tumour histology and by oestrogen receptor expression. FINDINGS: Breast cancer risk increased by a factor of 1·050 (95% CI 1·044-1·057; p<0·0001) for every year younger at menarche, and independently by a smaller amount (1·029, 1·025-1·032; p<0·0001), for every year older at menopause. Premenopausal women had a greater risk of breast cancer than postmenopausal women of an identical age (RR at age 45-54 years 1·43, 1·33-1·52, p<0·001). All three of these associations were attenuated by increasing adiposity among postmenopausal women, but did not vary materially by women's year of birth, ethnic origin, childbearing history, smoking, alcohol consumption, or hormonal contraceptive use. All three associations were stronger for lobular than for ductal tumours (p<0·006 for each comparison). The effect of menopause in women of an identical age and trends by age at menopause were stronger for oestrogen receptor-positive disease than for oestrogen receptor-negative disease (p<0·01 for both comparisons). INTERPRETATION: The effects of menarche and menopause on breast cancer risk might not be acting merely by lengthening women's total number of reproductive years. Endogenous ovarian hormones are more relevant for oestrogen receptor-positive disease than for oestrogen receptor-negative disease and for lobular than for ductal tumours.

Novel loci for adiponectin levels and their influence on type 2 diabetes and metabolic traits: a multi-ethnic meta-analysis of 45,891 individuals.

Circulating levels of adiponectin, a hormone produced predominantly by adipocytes, are highly heritable and are inversely associated with type 2 diabetes mellitus (T2D) and other metabolic traits. We conducted a meta-analysis of genome-wide association studies in 39,883 individuals of European ancestry to identify genes associated with metabolic disease. We identified 8 novel loci associated with adiponectin levels and confirmed 2 previously reported loci (P = 4.5×10(-8)-1.2×10(-43)). Using a novel method to combine data across ethnicities (N = 4,232 African Americans, N = 1,776 Asians, and N = 29,347 Europeans), we identified two additional novel loci. Expression analyses of 436 human adipocyte samples revealed that mRNA levels of 18 genes at candidate regions were associated with adiponectin concentrations after accounting for multiple testing (p<3×10(-4)). We next developed a multi-SNP genotypic risk score to test the association of adiponectin decreasing risk alleles on metabolic traits and diseases using consortia-level meta-analytic data. This risk score was associated with increased risk of T2D (p = 4.3×10(-3), n = 22,044), increased triglycerides (p = 2.6×10(-14), n = 93,440), increased waist-to-hip ratio (p = 1.8×10(-5), n = 77,167), increased glucose two hours post oral glucose tolerance testing (p = 4.4×10(-3), n = 15,234), increased fasting insulin (p = 0.015, n = 48,238), but with lower in HDL-cholesterol concentrations (p = 4.5×10(-13), n = 96,748) and decreased BMI (p = 1.4×10(-4), n = 121,335). These findings identify novel genetic determinants of adiponectin levels, which, taken together, influence risk of T2D and markers of insulin resistance.

Emancipatory pedagogies in a grade 11 social studies classroom

This study aimed to uncover the incorporation of transformative pedagogies into the social studies curriculum. This educational approach aims to educate students about a variety of forms of oppression based on race, gender, sexuality, class, ethnicity, and culture, through the use of dialogue to uncover the students' understanding and personal experience with these concepts. This study examined the impact of discussing these topics in a grade 11 class of 22 White students (of various cultural, ethnic, and religious backgrounds). The teacher, Kelvin, and two of his students were interviewed and his class was observed on four occasions over a 2-week period. Based on the data I collected, I argue that a range of emancipatory teaching approaches should be used in critical classroom discourse. These different approaches emphasize the importance of critical thinking, the ability to recognize and combat oppression, the understanding and respect of different cultures, and the ability to recognize the impact of gender and sexuality on the past and present. These are life skills that extend beyond the curriculum (Freire, 1970; Giroux, 1988; hooks, 1994). This study fills a theory to practice gap in the research literature on transformative practice within Canadian contexts. The findings are important for several reasons. Firstly, they illustrated how the teacher's ideology and personal history affect hislher teaching and learning philosophies and approach to teaching. This has implications for the overall classroom environment, what students learn, and how teachers are trained. Secondly, this study provided a glimpse of what transformative pedagogy could look like from a pragmatic standpoint and demonstrated the complexity of using these multiple approaches in the classroom.

Ethnic Minority Parents' Involvement in Education: Exploring and Understanding Their Experiences

Lopez, Scribner and Mahitivanichcha (2001) discuss the limited volume of literature that directly addresses ethnic minority parents' involvement in their children's education and they call upon researchers to fill this gap in the literature. This study is one such positive step with its focus on exploring how ethnic minority parents of secondary school students in southern Ontario understand their involvement in their children's education. Participants in the study included three ethnic minority parents recruited from a local adult education centre, and my parents who, as ethnics minority parents, also faced challenges trying to support their children as we progressed through the Ontario educational system. Primary data were collected through in-depth, open-ended interviews approximately one hour in length. Each of the five participants was interviewed twice. Secondary data included Ontario Ministry of Education documents that addressed programs, policies, and supports for ethnic minority students in Ontario secondary schools. Fieldnotes and a research journal also provided secondary data. The findings highlight, among other things, the challenges the participants faced as ethnic minority parents with a deep desire to support their children's education, but often lacking the cultural capital valued in the Ontario school system to meet that goal. As well, I benefited greatly from this research learning about the various ways in which, in my future work as a teacher of ethnic minority students, I can integrate the knowledge, skills, and experiences of ethnic minorities into my practice to ensure that parents of the non-dominant culture have an opportunity to become highly involved in the education of their children.

Ethnic Identity and School Ambition : the Case of Second Generation Youth from a Latin-American Background in Montreal

Ce mémoire propose d’étudier l’articulation entre l’identité ethnique (à l’adolescence) et l’ambition scolaire – ici définie comme l’ensemble des motivations, des moyens de persévérance et du niveau scolaire – notamment à travers les concepts d’assimilation et de la résistance culturelle (McAndrew 2008). Nous nous intéressons aux jeunes issus de l’immigration latino-américaine à Montréal. Il s’agit d’une analyse qualitative, plus précisément d’analyse de discours qui nous a permis de comprendre comment leurs expériences et leurs représentations des Latinos et des Québécois influencent leur identification ethnique ainsi que leurs perceptions et décisions en milieu scolaire. Les résultats de cette étude démontrent que l’identification ethnique, en corrélation avec le statut socio-économique et le genre, semble être liée à l’ambition scolaire. Malgré une certaine confirmation de la relation classique entre statut socio-économique et niveau de scolarité, les discours des participants ont permis de faire ressortir une particularité ethnique susceptible de contribuer à expliquer le choix de continuer aux études supérieures. Cet impact est plus important chez les jeunes femmes de notre échantillon; celles avec le niveau de scolarité le moins élevé, ont un statut socio-économique moindre et s’identifient davantage à la culture latino, en contraste avec celles les plus éduquées ayant aussi un statut socio-économique supérieur et qui s’identifiaient davantage à la culture québécoise.

Lorrie Moore collection, 'A Little Ethnic Kink Is Always Good to See”: Jewish performance anxiety and anti-passing in the fiction of Lorrie Moore

This essay explores the ways in which the performance of Jewish identity (in the sense both of representing Jewish characters and of writing about those characters’ conscious and unconscious renditions of their Jewishness) is a particular concern (in both senses of the word) for Lorrie Moore. Tracing Moore's representations of Jewishness over the course of her career, from the early story “The Jewish Hunter” through to her most recent novel, A Gate at the Stairs, I argue that it is characterized by (borrowing a phrase from Moore herself) “performance anxiety,” an anxiety that manifests itself in awkward comedy and that can be read both in biographical terms and as an oblique commentary on, or reworking of, the passing narrative, which I call “anti-passing.” Just as passing narratives complicate conventional ethno-racial definitions so Moore's anti-passing narratives, by representing Jews who represent themselves as other to themselves, as well as to WASP America, destabilize the category of Jewishness and, by implication, deconstruct the very notion of ethnic categorization.

Role of genetic polymorphism peroxisome proliferator-activated receptor-gamma2 Pro12Ala on ethnic susceptibility to diabetes in South-Asian and Caucasian subjects: Evidence for heterogeneity

OBJECTIVE: To determine whether the peroxisome proliferator-activated receptor (PPAR)-gamma Pro12ala polymorphism modulates susceptibility to diabetes in South Asians. RESEARCH DESIGN AND METHODS: South Asians (n = 697) and Caucasians (n = 457) living in Dallas/Forth Worth, Texas, and South Asians living in Chennai, India (n = 1,619), were enrolled for this study. PPAR-gamma Pro12Ala was determined using restriction fragment-length polymorphism. Insulin responsiveness to an oral glucose tolerance test (OGTT) was measured in nondiabetic subjects. RESULTS: The Caucasian diabetic subjects had significantly lower prevalence of PPAR-gamma 12Ala when compared with the Caucasian nondiabetic subjects (20 vs. 9%, P = 0.006). However, there were no significant differences between diabetic and nondiabetic subjects with reference to the Pro12Ala polymorphism among the South Asians living in Dallas (20 vs. 23%) and in India (19 vs. 19.3%). Although Caucasians carrying PPAR-gamma Pro12Ala had lower plasma insulin levels at 2 h of OGTT than the wild-type (Pro/Pro) carriers (76 +/- 68 and 54 +/- 33 microU/ml, respectively, P = 0.01), no differences in either fasting or 2-h plasma insulin concentrations were found between South Asians carrying the PPAR-gamma Pro12Ala polymorphism and those with the wild-type genotype at either Chennai or Dallas. CONCLUSIONS: Although further replication studies are necessary to test the validity of the described genotype-phenotype relationship, our study supports the hypothesis that the PPAR-gamma Pro12Ala polymorphism is protective against diabetes in Caucasians but not in South Asians.

The history curriculum and its personal connection to students from minority ethnic backgrounds

Whereas history is seen by some as crucial in developing a sense of identity and fostering social cohesion, it is however, often based around narrowly nationalistic views of the past, and yet little is known about how students relate to the past they are taught. Thus, this paper focuses on the history curriculum and the ways in which students aged 12-14, from different ethnic backgrounds, relate to it. Moreover, the small-scale study which enabled this paper, focused, in particular, on whether students enjoyed and valued history and whether they felt any sense of personal connection to the topics studied. Drawing on survey data collected from 102 students and focus group discussions with 42 students, from two high schools, the findings indicate that although many students enjoy history, they fail to fully understand its value. Additionally most students, especially those from minority ethnic backgrounds, feel a lack of personal connection to the past, as they do not see themselves in the history they are taught.

Artificial Equations, Artificial Distinctions: Language that Poisons the Waters of Ethnic Relations

“It is my contention at this point that when race relations on campuses get better, it is in spite of, not because of, the proliferation of jargon-based rhetoric about diversity.”

Frequency of LCT -13910C>T single nucleotide polymorphism associated with adult-type hypolactasia/lactase persistence among Brazilians of different ethnic groups

Abstract Background Adult-type hypolactasia, the physiological decline of lactase some time after weaning, was previously associated with the LCT -13910C>T polymorphism worldwide except in Africa. Lactase non-persistence is the most common phenotype in humans, except in northwestern Europe with its long history of pastoralism and milking. We had previously shown association of LCT -13910C>T polymorphism with adult-type hypolactasia in Brazilians; thus, we assessed its frequency among different Brazilian ethnic groups. Methods We investigated the ethnicity-related frequency of this polymorphism in 567 Brazilians [mean age, 42.1 ± 16.8 years; 157 (27.7%) men]; 399 (70.4%) White, 50 (8.8%) Black, 65 (11.5%) Brown, and 53 (9.3%) Japanese-Brazilian. DNA was extracted from leukocytes; LCT -13910C>T polymorphism was analyzed by PCR-restriction fragment length polymorphism. Results Prevalence of the CC genotype associated with hypolactasia was similar (57%) among White and Brown groups; however, prevalence was higher among Blacks (80%) and those of Japanese descent (100%). Only 2 (4%) Blacks had TT genotype, and 8 (16%) had the CT genotype. Assuming an association between CC genotype and hypolactasia, and CT and TT genotypes with lactase persistence, 356 (62.8%) individuals had hypolactasia and 211 (37.2%) had lactase persistence. The White and Brown groups had the same hypolactasia prevalence (~57%); nevertheless, was 80% among Black individuals and 100% among Japanese-Brazilians (P < 0.01). Conclusion The lactase persistence allele, LCT -13910T, was found in about 43% of both White and Brown and 20% of the Black Brazilians, but was absent among all Japanese Brazilians studied.

SLCO1B1 rs4149056 polymorphism associated with statin-induced myopathy is differently distributed according to ethnicity in the Brazilian general population: Amerindians as a high risk ethnic group

Background Recent studies reported the association between SLCO1B1 polymorphisms and the development of statin-induced myopathy. In the scenario of the Brazilian population, being one of the most heterogeneous in the world, the main aim here was to evaluate SLCO1B1 polymorphisms according to ethnic groups as an initial step for future pharmacogenetic studies. Methods One hundred and eighty-two Amerindians plus 1,032 subjects from the general urban population were included. Genotypes for the SLCO1B1 rs4149056 (c.T521C, p.V174A, exon 5) and SLCO1B1 rs4363657 (g.T89595C, intron 11) polymorphisms were detected by polymerase chain reaction followed by high resolution melting analysis with the Rotor Gene 6000® instrument. Results The frequencies of the SLCO1B1 rs4149056 and rs4363657 C variant allele were higher in Amerindians (28.3% and 26.1%) and were lower in African descent subjects (5.7% and 10.8%) compared with Mulatto (14.9% and 18.2%) and Caucasian descent (14.8% and 15.4%) ethnic groups (p < 0.001 and p < 0.001, respectively). Linkage disequilibrium analysis show that these variant alleles are in different linkage disequilibrium patterns depending on the ethnic origin. Conclusion Our findings indicate interethnic differences for the SLCO1B1 rs4149056 C risk allele frequency among Brazilians. These data will be useful in the development of effective programs for stratifying individuals regarding adherence, efficacy and choice of statin-type.
