Intra-ethnic and inter-ethnic marriage and divorce in Hawaii

A comparison of intra- and inter-ethnic divorce rates in Hawaii showed that inter-ethnic marriages resulted in a higher proportion of divorces than did intra-ethnic marriages when the marriage data used had to do with all marriages occurring in Hawaii. However, a sizeable portion of marriages in Hawaii are of nonresidents who, if they divorce, probably divorce elsewhere. Nonresident marriages are chiefly intra-ethnic marriages of Caucasians. When examining the proportions of divorces to resident marriages, within-group marriages are more at risk than inter-ethnic marriages. As in prior research, persons who marry members of other racial/ethnic groups tend to marry persons from groups with income levels similar to their own. As in previous reports, some cross-ethnic combinations appeared more at risk for divorce than did others. Group income appeared to be a predictor of risk. When considering only resident marriages as related to divorces, those marriages in which the bride was from a higher income group than the groom were at a significantly greater risk for divorce than marriage in which the bride came from an income group lower than that of the groom.     

Ethno-nationalist claims in southern Nigeria: insights from Yoruba and Ijaw nationalisms since the 1990s

There are several competing explanations for the rise in ethnic nationalisms in Nigeria, but there is an agreement that identity politics and conflicts tend to incubate and thrive best in underdeveloped settings. To this can be added the crises produced by prolonged military rule, during which the intensity of contestations for power translated the quest for ethnic ascendancy into the rule rather than the exception. This essay provides the contexts and extenuating circumstances in which ethnic nationalisms by the Yoruba and the Ijaw in southern Nigeria became salient and militant from the 1990s onward. Despite concrete variations in their ethno-nationalist projects, the Yoruba and the Ijaw are shown to be similar in several respects: both, for instance, contain salient strands of ‘self-determination’ translating at best to pseudo-separatist inclinations towards the decentralization and devolution of power and authority as constituted presently in Nigeria.     

Marriage and the maintenance of ethnic group boundaries: the case of Mauritius

Research on how cognitive and cultural biases shape marital decisions in Mauritius suggests that ethnic endogamy will remain the norm and maintain ethnic group boundaries. Results of a pile sorting exercise of Mauritian university students intimates that preferences for ethnic endogamy are paramount and override class-based considerations. Thus, despite socio-economic stratification within each ethnic group, inter-ethnic marriage is not common. Results from in-depth interviews suggest that individuals and their parents prefer to marry within their ethnic group to ensure that their spouse will abide by ethnically-specific norms and conventions, increasing the chances of coordinating reciprocal exchanges within a marriage. The presence of some inter-ethnic marriage does not weaken the boundaries between groups because children of inter-ethnic marriages tend to take on the ethnic identity and corresponding cultural norms of a single parent as a strategy to better negotiate social relations, and to marry someone of that same ethnicity.     

Citizenship and Resource Competition in Nigeria

This article discusses the growing tension between constitutionally defined citizenship and socially accepted practices of “we–they dichotomies” as a turbulent component of the national question discourse in Nigeria. It examines the adoption of dual citizenship across the country as well as how this generates violent ethnic conflict. Importantly, while citizenship refers to one’s full membership of a sovereign political community acquired either by birth, naturalisation or any other process legitimised and recognised by the supreme law of the state, indigeneship, on the other hand, is a discriminatory policy employed by local or provincial governments for protecting the rights of their so–called indigenous populations to employment, political power and other resources of the regions or states against domination by alien populations and outsiders. It is argued that while such distinctions have been made possible inter alia by Nigeria’s multi–ethnic character, the ensuing struggles and tensions have been driven by the normless competition over resource allocation. These have especially been the case in instances where ethno–territorial cleavages have been the primary beneficiaries and targets of such resource allocation. This article discusses land as a major economic resource over which heated ethnic conflicts have taken place in Nigeria. Drawing on the conflicts between Hausa–Fulani pastoralists and Yoruba farmers in South–Western Nigeria, it examines the question of how disputed access to land and water has underlain an almost permanent basis of conflict in Nigeria as well as their implications for the country’s fledgling democracy. How does the struggle over land affect the articulation of the citizenship question in Nigeria? How have scarcity and competition over resources affected the contest over citizenship and the forging of nationhood among natives and settlers in South–Western Nigeria? How have colonial framings of socially accepted practices of indigeneship entrenched an understanding of the state in Nigeria as a representation of permanently defined subnational conceptions of ethnic citizenship? What role can the state in Nigeria play towards transforming the multiplicities of traditional societies into coherent political societies as a basis for (i) eliciting deference and devotion from the individual to the claims of the state, and ultimately for (ii) increasing cultural homogeneity, political integration and value consensus? Drawing on data generated from an ethnographic study carried out in South–Western Nigeria between October 2009 and March 2015, this study interrogates these questions.     

The russian gene pool: the gene geography of Alu insertions (ACE, APOA1, B65, PV92, TPA25)

For the first time, an analysis of five Alu insertion loci (ACE, APOA1, B65, PV92, TPA25) has been carried out in 10 Russian populations (1088 individuals) covering the whole historical area of the Russian ethnos. Depending on the locus, Russian populations exhibit similarity to their Western (European populations) or Eastern (populations of the Ural region) neighbors. Considering the frequencies of the studied Alu-insertions, the Russian gene pool exhibits low variation: average interpopulation variation (d) was 0.007, whereas on classical markers, mtDNA and Y chromosome, heterogeneity of the Russian gene pool is essentially higher (0.013, 0.033, 0.142, respectively). Therefore, on the intra-ethnic level, this set of five Alu insertions has low variation. However, a clear pattern was obtained in inter-ethnic comparison of 13 East European ethnic groups, which formed three clusters in accordance with their historical and geographical position: East Slavic, Caucasian and South Ural clusters. The obtained data confirm the efficiency of using Alu insertions for studying genetic differentiation and gene pool history of East European populations.     

Unexpected Consequences: Wildlife Conservation and Territorial Conflict in Northern Kenya

This article is concerned with the implementation of community-based conservancies (CBC) in conflict-ridden pastoralist areas of northern Kenya and whether the creation of protected areas can facilitate the resolution of conflict. Evidence from ethnographic research in East Pokot, Kenya, reveals a mixed picture. In the last decade, three CBCs were established along the administrative borders. Two of them are located in contested areas between the Pokot and neighboring pastoralists. In order to ensure their long-term success in terms of wildlife conservation and economic viability they must act as catalysts for inter-ethnic conflict resolution. In one case, the implementation proved successful, while in the other it exacerbated tensions and led to ethnic violence. In addition, issues of conservation are also embedded in deeper intra-societal struggles over the reconfiguration and renegotiation of access to and control over land. Drawing on ethnographic data and recent literature this research sheds light on unexpected consequences of CBC.     

Reconciling the contact and threat hypotheses: does ethnic diversity strengthen or weaken community inter-ethnic relations?

The literature on whether community diversity has a positive effect on individuals' inter-ethnic attitudes (contact hypothesis) or a negative effect (threat hypothesis) remains inconclusive. Most studies infer mechanisms of contact or threat based on the relationship between diversity and mean levels of prejudice in a community. We suggest that both processes of threat and contact may be occurring with increasing diversity. By applying a measure of individual-level contact, this paper demonstrates that increasing community diversity does have a negative effect on inter-ethnic attitudes but only among individuals without inter-ethnic ties. Among those who do form ties, increasing diversity has no effect – that is, contact moderates the negative effect of community diversity. However, this relationship is further moderated by levels of disadvantage in the community. This paper has important implications for the use of the contact/threat hypotheses in studies of contextual diversity and the wider debate on rising diversity in the UK.     

Two Renowned Nigerian Scholars: Ikenna Nzimiro and Victor Chikesie Uchendu

The article honors two Nigerian anthropologists of Igbo background who recently passed away. Both scholars made major contributions to a broad range of scholarly thought in anthropology and in general social science to crucial issues in Nigerian politics, society and life. Nzimiro is considered in terms of his traditional anthropological training in Germany and England, through which he investigated four Niger River basin communities, and then his emergence as a Marxist anthropologist for the rest of his life in Nigeria, where he consistently critiqued neocolonialism in Nigeria. He explored issues of ethnicity, the Nigerian civil war, militarism, the state of the social sciences, the environment, Oguta culture, where he was born, ethnic conflicts, conditions at Nigerian universities, and other issues. Nzimiro generally rejected the post-colonial world, arguing that it was not revolutionary enough. Uchendu dealt with many of the same issues, but in contrast to Nzimiro he did so by accepting the existence of post-colonial Nigeria, though suggesting many ways to improve education, the environment, cultural and national transition, dependency theory, and to study urbanization and ethnicity, while also writing a major work on Igbo culture. Both authors are honored for their critiques of Nigerian society, as well as their contributions to Igbo ethnology.     

Family relations and the attitude towards ethnic minorities as close kin by marriage

Using data from a nationally representative survey (N=6,632), this study examines among native Dutch adults the relationship between current family characteristics and the attitude towards having ethnic minority members as close kin by marriage. The findings indicate that the opposition to intermarriage is quite high but differs towards different ethnic minority groups. Family cohesion – strength of family ties, the adherence to family norms and contact frequency – is related to lower acceptance of inter-ethnic marriage. This supports the idea that when the ties are tightly knit, family members have an incentive to keep ‘cultural strangers’ out of the family. In contrast, family warmth – feelings of affection and emotional support – is related to higher acceptance of inter-ethnic marriage. This is in agreement with the idea that warm and emotionally supportive family relationships can lead to the development of generalized trust, empathy and open-mindedness.     

Contact,trust and social capital in Northern Ireland: a qualitative study of three mixed communities

In a recent paper, Robert Putnam (2007) challenges the contact hypothesis by arguing that ethnic diversity causes people to ‘hunker down’ and essentially withdraw themselves from society. Drawing on qualitative data collected from three mixed communities in Northern Ireland, this paper explores the extent and quality of contact experienced by Protestants and Catholics in their everyday lives. Themes emerging from our data are generally consistent with the contact hypothesis. There is also some support for Putnam's theory that mixed environments can induce ‘hunkering down’ and that inter-group trust may be compromised. However, our data challenge Putnam's argument that these responses are a consequence of ‘anomie’ or ‘social malaise’. Rather, we find that withdrawal from social activity in the neighbourhoods we observed was a calculated response at times of threat, often aimed at protecting existent positive inter-ethnic relations.     

Accommodating ethnic diversity in a modernizing democratic state: theory and practice in the case of Mauritius

This article examines the accommodation of diverse ethnic communities in developing democratic states. We examine those means of managing or reducing ethnic conflicts identified in the literature that have actually been employed in Mauritius, one of the most successful ethnically-diverse developing states in the world. Our findings suggest that traditional elite-dominated means of regulating conflicts are becoming less effective in an age of growing populism and declining deference to elites, and that new means of incorporating ethnic communities into the functioning of the state are required. The key means in the case of Mauritius seem to have been the development of a competent and representative public service; the incorporation of civic associations, including those with an ethnic character, in the policy process by means of a civic network; and the evolution of political parties into ethnically diverse organizations. Inclusiveness appears to be more important than strict proportionality.     

Metabolic specialization and the assembly of microbial communities

Metabolic specialization is a general biological principle that shapes the assembly of microbial communities. Individual cell types rarely metabolize a wide range of substrates within their environment. Instead, different cell types often specialize at metabolizing only subsets of the available substrates. What is the advantage of metabolizing subsets of the available substrates rather than all of them? In this perspective piece, we argue that biochemical conflicts between different metabolic processes can promote metabolic specialization and that a better understanding of these conflicts is therefore important for revealing the general principles and rules that govern the assembly of microbial communities. We first discuss three types of biochemical conflicts that could promote metabolic specialization. Next, we demonstrate how knowledge about the consequences of biochemical conflicts can be used to predict whether different metabolic processes are likely to be performed by the same cell type or by different cell types. We then discuss the major challenges in identifying and assessing biochemical conflicts between different metabolic processes and propose several approaches for their measurement. Finally, we argue that a deeper understanding of the biochemical causes of metabolic specialization could serve as a foundation for the field of synthetic ecology, where the objective would be to rationally engineer the assembly of a microbial community to perform a desired biotransformation.     

国家公园原住民对野生动物肇事的认知、意愿及其影响因素——以武夷山国家公园为例

国家公园原住民对野生动物肇事的态度直接影响野生动物保护政策有效实施以及人与野生动物共存机制。迄今,学术界鲜有从原住民认知与意愿角度探讨野生动物肇事的成果,基于自然保护地国家公园的相关研究尚未见报道。根据449份有效调查问卷及深度访谈数据,论文采用有序多分类Logistic回归方法,探讨武夷山国家公园原住民对野生动物肇事的认知、意愿及其影响因素。结果表明：（1）多数原住民经历过野生动物肇事,其农作物及牲畜受到严重损害,野猪（Sus scrofa）为研究区域主要的肇事动物。（2）种群数量增加、食物短缺和生存空间受限是野生动物肇事的主要原因。（3）学历、经历及认可政府应对肇事的方式对原住民防范野生动物肇事意愿的影响显著。在此基础上,提出遵循生态规律、保护栖息地、提升认知与意愿、实行社区共管、建立野生动物致害补偿机制以及引入野生动物致害赔偿保险等对策,希望能够深化对野生动物肇事特征及机理的科学认识,为有效缓解人与野生动物冲突、推进国家公园人与野生动物和谐提供政策参考。     

人熊冲突缓解措施研究进展——以三江源国家公园为例

人与熊科动物之间的冲突已成为亚洲、欧洲和美洲地区的一个普遍问题,科学有效的人熊冲突管控措施有助于人熊共存机制的建立。目前,全球范围内肇事熊科动物涉及7种,分别为棕熊、亚洲黑熊、美洲黑熊、北极熊、马来熊、懒熊和眼镜熊。肇事类型主要包括伤人、捕食牲畜、入侵房屋、损害庄稼、袭击蜂箱以及翻食垃圾。引发人熊冲突的原因与人类活动范围扩大、熊科动物种群数量上升、熊科动物生境质量下降、熊科动物自然食源周期性短缺、人类食物来源易获得性以及公众对肇事熊的容忍度下降有关。国际上已有的人熊冲突缓解措施包括物理措施、生物措施、化学措施以及政策导向性措施,然而,多数措施的制定仅停留在措施本身的技术层面上,缺乏对地方实际情况和冲突驱动因素的分析。西藏棕熊属于棕熊的一种稀有亚种,生活在靠近人类的中亚高海拔地区。在中国三江源国家公园地区,人类与西藏棕熊的冲突引起了人们的关注,为协助制订有效的保育目标、解决区内人熊冲突问题,提出以下缓解建议:(1)缓解措施的制定需因地而异,综合考虑地方实际情况,如地理环境、法律法规、民俗文化以及宗教信仰等;(2)冲突类型多样,防熊措施需持续更新与完善;(3)加强人类社会发展与熊科动物生存之间的关系研究,探索人们生产生活方式的改变与熊科动物行为变化之间的关系;(4)加强棕熊生态学方面的研究,从棕熊生境质量、种群动态、自然食源以及生态系统完整性等方面去深入挖掘人熊冲突的驱动因素,进而从根本上制定缓解措施,促进三江源国家公园地区人熊共存。     

Social rationality and scales of action: inter-ethnic relations in cockfighting and game-fishing,Raiatea, French Polynesia

This article challenges the notion of economic rationality as a criterion for explaining ethnic boundary maintenance. It offers an ethnographic analysis of inter-ethnic relations in the context of games (cockfights and game-fishing contests) in the island of Raiatea (French Polynesia). Although all players engage in the same basic gambling practices, money is differentially scaled and mobilized by the Tahitian and Chinese participants. Building on recent pragmatic approaches to rationality, it is shown that the players' rationalities differ not from the point of view of economic maximization, but only in so far as they participate in social relations at different scales.     

The contact–prejudice relationship among ethnic minorities: examining personal discrimination as a boundary condition

This paper contributes to the literature on how perceived discrimination influences the impact of intergroup contact among ethnic minority members. Previous research has shown that perceived group discrimination inhibits the positive outcomes of intergroup contact among ethnic minority members. In extension, this paper examines whether perceived personal discrimination has a similar negative impact as a boundary condition of the contact–prejudice relationship among ethnic minority members. Analyses expand previous intergroup contact research by showing that the impact of intergroup contact is uniform across various levels of perceived personal discrimination. This finding suggests that the otherwise harmful consequences of perceived personal discrimination can be effectively counterbalanced by positive contact experiences among ethnic minority members. Analyses use evidence from a national probability sample, which was fielded in 2006 to examine some of the largest ethnic minority groups (N?=?3,462). The concluding section discusses the theoretical implications of the empirical findings.     

Conflicting selection pressures on reproductive functions and speciation in plants

Recent developments in the field of genetic divergence and speciation focus more on diversifying processes than on geographic mode of speciation (i.e. allopatric versus sympatric). Some of these new theories concern speciation driven by conflicts between the sexes. Even though it is well known that the two reproductive functions in plants can have different selective optima, sexual selection in plants is by many assumed to be weak or non-existent. Here we outline potential sexual conflicts in plants and discuss how selection pressures generated by such conflicts may influence genetic divergence. There is opportunity for conflicting selection pressures between individuals, such as manipulative pollen traits that enhance male reproductive success at the expense of the female reproductive function. Within individual plants, fitness of the male function (pollen export) and fitness of the female function (pollen import) may be optimised by different traits, leading to conflicting selection pressures in relation to pollen transfer. This may affect selection for floral specialisation versus floral generalisation in animal-pollinated species. We believe that selection pressures generated by sexual conflict need to be appreciated in order to fully understand microevolutionary processes which may lead to genetic divergence and speciation in plants.     

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.     

Ethnic school context and the national and sub-national identifications of pupils

In various European countries, policy-makers strive for educational desegregation to enhance pupils' national identifications. Since little empirical evidence supports such a policy and social identity theorists emphasize the importance of context, this article examines the impact of ethnic school composition – measured by the proportion of non-natives and ethnic heterogeneity – on the national (Belgian) and sub-national (Flemish) identifications of pupils. Multi-level data analyses from the surveying of 2,845 pupils (aged 10–12) in sixty-eight Flemish primary schools reveal differential effects for natives and non-natives. While the proportion of non-natives at school is negatively associated with non-native pupils' identifications, it is positively related to native pupils' identifications. In general, the ethnic heterogeneity of the school is negatively associated with pupils' national and sub-national identifications. Our findings indicate that the relation between ethnic school composition and pupils' identifications is mediated by the latter's inter-ethnic friendships. The consequences of these findings for educational policy are discussed.
