黎族的体成分与体质特征

1982年和1988年已经有学者报道了黎族体质人类学研究资料,近年来又报道了黎族的分子人类学研究成果。目前未见关于黎族身体组成成分的研究,也没有当前黎族的体质人类学数据。2014年11月,在海南省五指山市5个黎族村寨进行607例(男为308例,女为299例)黎族成人的人体测量。研究发现,黎族人偏瘦,肌肉较发达。随年龄增长,黎族男性体脂率的增加,主要是躯干脂肪率增大造成的,与四肢脂肪率关系不大。男性由于骨量、躯干和四肢肌肉量的下降造成瘦体质量的逐渐减小。随年龄增长,黎族女性的体脂率呈线性增大,总肌肉量呈线性减小。体脂率的逐渐增大是由于躯干和四肢的脂肪率逐渐增加造成的,总肌肉量的逐渐减小是左下肢肌肉量、躯干肌肉量逐渐下降造成的。黎族男女均为圆头型、高头型、中头型、阔面型、中鼻型、中躯干型、中胸型、宽肩型、中骨盆型、中腿型。与30年前黎族头面部资料相比,本文测量的黎族头宽、面宽值较大,头更圆些、更阔些,面更阔些,红唇较薄,形态面高值较小,男性鼻宽值较小。     

Hip-Hop to Health Jr. for Latino preschool children

Objective: Hip‐Hop to Health Jr. was a diet/physical activity intervention designed to reduce gains in BMI (kilograms per meter squared) in preschool minority children. Research Methods and Procedures: Twelve predominantly Latino Head Start centers participated in a group‐randomized trial conducted between Fall 2001 and Winter 2003. Six centers were randomized to a culturally proficient 14‐week (three times weekly) diet/physical activity intervention. Parents participated by completing weekly homework assignments. The children in the other six centers received a general health intervention that did not address either diet or physical activity. The primary outcome was change in BMI, and secondary outcomes were changes in dietary intake and physical activity. Measures were collected at baseline, post‐intervention, and at Years 1 and 2 follow‐up. Results: There were no significant differences between intervention and control schools in either primary or secondary outcomes at post‐intervention, Year 1, or Year 2 follow‐ups. Discussion: When Hip‐Hop to Health Jr. was conducted in predominantly black Head Start centers, it was effective in reducing subsequent increases in BMI in preschool children. In contrast, when the program was conducted in Latino centers, it was not effective. Although the intervention did not prevent excessive weight gain in Latino children, it was very well received. Future interventions with this population may require further cultural tailoring and a more robust parent intervention.

Minority politics in the Middle East and North Africa: the prospects for transformative change

This special issue explores the prospects for what Jacob Mundy calls ‘transformative minority politics’ in the Middle East and North Africa (MENA) region – that is, a form of minority politics that strengthens democratic reform in the region, and that helps deepen a culture of human rights and democratic citizenship. The cases examined in the special issue include the Amazigh in North Africa, the Copts in Egypt, the Kurds in Iraq, the Palestinians in Israel, the ‘minoritarian’ regimes in Syria and Bahrain, and the various ethnic minorities in Iran. In this introduction, we try to situate this debate in a larger historical and international context, identifying some of the factors that might help support a new transformative minority politics in the region, while also emphasizing the factors that have inhibited it in the past, and why they remain powerful.     

Perceived threat and exclusionary attitudes towards foreign workers in Israel

The present article focuses on determinants of attitudes towards granting social rights to overseas labour migrants in Israeli society. The analysis is based on a national representative sample of the adult population in Israel. The findings reveal that a substantial number of respondents (both Jews and Arabs) oppose granting equal social rights (i.e. education, welfare, health, housing) to foreign workers. These attitudes can partially be explained as resulting from perceived threat to social and economic well-being of individuals as well as threat to national identity and Jewish character of the state. Part of the exclusionary attitudes that cannot be attributed to threats, are explained by individuals’ socio-economic characteristics, ethnicity and political orientation. The findings are discussed within the context of Israel as an ethno-national state.     

Conflict resolution attempts in self-determination disputes: the significance of local minority groups concerns in the Philippines and Sri Lanka

The way in which the minority within minority question is solved has implications for settlement of self-determination conflicts. This paper examines how this question plays out in connection with negotiations of peace agreements. It focuses on the negotiations on the Bangsamoro Juridical Entity in the Philippines in 2008 and the Fifth Peace Process in Sri Lanka in 2002–06. By analysing constitutional design options in terms of integration, power sharing and power dividing, it outlines how minority concerns are articulated and eventually how they have implications for negotiations. The absence of power-sharing guarantees was a major concern among elites not associated with the self-determination project, both at the national and the local level. They blocked implementation of the deals, insisting instead on integration and power dividing. These findings highlight the shortcomings of negotiations that overlook the multifaceted majority/minority conflicts at national and local levels and how they are interlinked.     

Organizational life and political incorporation of two Asian immigrant groups: A case study

Civil society is the foundation of a healthy democracy but its immigrant element has received little attention. This paper is a case study of immigrant organizations of highly skilled Asian Indians and Chinese immigrants in a suburban town of Edison, New Jersey. I find that civic participation of Asian Indian immigrants spills over into political incorporation while Chinese immigrant organizations remain marginalized. I argue that local processes of racialization are central in explaining differences in political incorporation of immigrants. In the local context, the Chinese are seen as successful but conformist model minorities and Asian Indians as invaders and troublemakers. The racialization of Asian Indians has resulted in more political activity and higher levels of political visibility of their organizations. The results highlight shortcomings of current assimilation theories, which give little space to civic and political incorporation and view human capital in an unqualifiedly positive light.     

Genetic polymorphism of mitochondrial DNA HVS-I and HVS-Ⅱ of Chinese Tu ethnic minority group

We analyzed the two hypervariable segments HVS-Ⅰ and HVS-Ⅱ of 108 Chinese Tu ethnic minority group samples for forensic and population genetics purposes.Comparing with Anderson sequence,79 polymorphic loci in HVS-Ⅰ and 40 in HVS-Ⅱ were found in Chi-nese Tu ethnic minority group mtDNA sequences,and 90 and 64 haplotypes were then defined.Haplotype diversity and the mean pair-wise differences were 0.9903:±0.0013 and 5.7785 in HVS-Ⅰ,and 0.9777±0.0013 and 3.5819 in HVS-Ⅱ,respectively.By analyzing the hypervariable domain from nucleotide 1,6180 to 1,6193 in HVS-Ⅰ,we defined some new types of sequence variations.We also compared the relationship between Tu population and other populations using mtDNA HVS-Ⅰ sequences.According to Rst genetic distances,the phylogenetic tree showed that the Tu population,the Xi'an Han population,the Chinese Korean,and the Mongol ethnic group were in a clade.This indicated a close genetic relationship between them.There were far relations between the Tu population and other Chinese southern Han populations,Siberian,European,African,and other foreign populations.The results suggest that Tu population has a multi-origin and has also merged with other local populations.

The Relationship of Ethnicity,Socioeconomic Factors,and Overweight in U.S. Adolescents

Objective: To examine the extent to which race/ethnic differences in income and education account for sex‐specific disparities in overweight prevalence in white, African American, Hispanic, and Asian U.S. teens. Research Methods and Procedures: We used nationally representative data collected from 13,113 U.S. adolescents enrolled in the National Longitudinal Study of Adolescent Health. Logistic regression models were used to examine the relationship of family income and parental education to overweight prevalence (body mass index ≥ 85th percentile of age and sex‐specific cutoff points from the 2000 Centers for Disease Control and Prevention/National Center for Health Statistics growth charts). In addition, we used coefficients from our logistic regression models to project the effects on overweight prevalence of equalizing the socioeconomic status (SES) differences between race/ethnic groups. Results: Keeping adolescents in their same environments and changing only family income and parental education had a limited effect on the disparities in overweight prevalence. Ethnicity‐SES‐overweight differences were greater among females than males. Given that overweight prevalence decreased with increasing SES among white females and remained elevated and even increased among higher SES African‐American females, African‐American/white disparity in overweight prevalence increased at the highest SES. Conversely, disparity was lessened at the highest SES for white, Hispanic, and Asian females. Among males, disparity was lowest at the average SES level. Discussion: One cannot automatically assume that the benefits of increased SES found among white adults will transfer to other gender‐age‐ethnic groups. Our findings suggest that efforts to reduce overweight disparities between ethnic groups must look beyond income and education and focus on other factors, such as environmental, contextual, biological, and sociocultural factors.
