The benefits of social capital: close social bonds among female baboons enhance offspring survival

Sociality has evolved in many animal taxa, but primates are unusual because they establish highly differentiated bonds with other group members. Such bonds are particularly pronounced among females in species like baboons, with female philopatry and male dispersal. These relationships seem to confer a number of short-term benefits on females, and sociality enhances infant survival in some populations. However, the long-term consequences of social bonds among adult females have not been well established. Here we provide the first direct evidence that social relationships among female baboons convey fitness benefits. In a group of free-ranging baboons, Papio cynocephalus ursinus, the offspring of females who formed strong social bonds with other females lived significantly longer than the offspring of females who formed weaker social bonds. These survival benefits were independent of maternal dominance rank and number of kin and extended into offspring adulthood. In particular, females who formed stronger bonds with their mothers and adult daughters experienced higher offspring survival rates than females who formed weaker bonds. For females lacking mothers or adult daughters, offspring survival was closely linked to bonds between maternal sisters. These results parallel those from human studies, which show that greater social integration is generally associated with reduced mortality and better physical and mental health, particularly for women.     

The multiplier effect: how the accumulation of cultural and social capital explains steep upward social mobility of children of low-educated immigrants

ABSTRACT

We introduce what we have coined the multiplier effect. We explain the steep upward mobility of children of low-educated immigrants by studying how they overcome obstacles on their regular pathway, via alternative routes or through loopholes in the education and labour market system. The idea of the multiplier effect is that they virtually propel themselves forward in their careers. Essential is that each successful step forward offers new possibilities on which they build, thereby accumulating cultural and social capital and multiplying their chances of success. Initial small differences with their less successful co-ethnic peers generate an increasingly wider gap over time. Cultural and social capital theories primarily explain the reproduction of inequalities in society. The multiplier effect explains the breaking of the perpetual cycle of this reproduction, enabling steep upward mobility even when this group does not initially possess the right cultural and social capital to be successful.     

耦合生态资本和社会资本的生态资源价值化体系分析

运用实地调研和理论分析的方法对中国生态资源价值化体系的变迁进行分析,并进一步提出耦合生态资本和社会资本的生态资源价值化理论框架。按照价值化的逻辑总结出价值化两条路径：流量价值化和存量价值化,并通过梳理科技文献指出现有研究的不足：流量价值化缺乏"生态视角"和存量价值化缺乏"整体视角"。对比分析了不同时期中国生态资源价值化变迁的特点,发现计划经济时期国家通过生态资源的公有和单要素管理,实现流量、存量的管控和生态资源收益的合理分配;在市场化改革前期,生态资源使用权与所有权的收益逐步分离,激励了社会资本带动生产力发展,但也造成了生态危机和贫富差距拉大等问题;在市场化后期,各地不断实践探索全生态要素治理,通过政府市场社会多方位联动追求共同富裕和生态文明目标的实现。指出生态资源价值体系与社会历史进程的关系,揭示了其背后社会资本与生态资本的耦合关系。最后,提出在市场化改革后期需要坚持"公共性"政党的领导,并在耦合社会资本与生态资本这一思想指导下构建的县镇村三级联动的生态资源价值化框架。研究结论为乡村振兴背景下中国生态资源价值化体系提供理论指导,为中国共产党领导下生态文明思想的人民性提供政治经济学的解释。     

Immigration,remittances, and transnational social capital formation: a Cuban case study

Social capital takes on distinctive meaning in the context of large-scale immigration from poor to rich countries. In this article, characteristics of social capital embedded in transnational networks and norms, conditions conducive to the formation of such networks, and effects such networks have are extrapolated from an analysis of how and why cross-border relations among Cuban-Americans and Cubans in their homeland have changed since the 1959 Castro-led revolution. The transnational social capital generating benefit on which the study focuses is remittances. Remittances are of growing global importance to less developed countries, and in some countries they generate more revenue than foreign aid and foreign investment. The analysis addresses a range of unintended as well as intended consequences remittances may have.     

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.     

Vietnamese migrant networks in Taiwan: the curse and boon of social capital

Drawing on ethnographic research on Vietnamese migrant workers in Taiwan, I seek to engage with and contribute to the scholarship on migrant networks and social capital. My research demonstrates that migrant networks are central to the social life of Vietnamese workers, offering not only a vital source of material and psychological support but also a platform where relationships are developed, sustained and contested. It reveals both productive and destructive potentials of social capital in situations where the migrant labourer becomes a disenfranchized underclass and their radius of trust is unsettled by physical displacement. Through this research I highlight the complexities and subjectivities in individual experiences of social capital and offer important insights into the various ways in which social networks are reinterpreted and reconfigured at the intersection of mobility, class and ethnicity within the context of Asia.     

Hui family migration in Northwest China: patterns,experiences and social capital

Based on an extensive questionnaire survey in three cities in Northwest China, this article identifies the factors influencing the sole, couple and family migration of Han and Hui. We find that Han migrants are more utility-oriented and tend to circulate among different places in order to maximize their utility. Hui migrants are more likely to seek opportunities to settle in destinations with their families. They rely on Hui communities and dedicate themselves to creating networks and accumulating social capital for their families. We suggest that the accumulation of bonding capital does not necessarily suggest the increase or decrease of bridging capital. Moreover, the ethnic community should be regarded neither in negative nor positive terms but rather as a coin with two sides, pro and con. The ethnic community is a vessel, which migrants can use for minimizing risks, improving livelihoods and fostering the settlement of families.     

Entrepreneurship in South African township tourism: the impact of interracial social capital

Ethnic entrepreneurship scholarship has demonstrated the importance of social capital for “minority” entrepreneurs, but these studies presume that social capital is co-ethnic. I complicate this assumption by investigating entrepreneurial black women and interracial social capital in South African township tourism, a niche market within the nation’s growing tourism industry. Drawing from ethnographic fieldwork conducted in two black townships in Cape Town, I spotlight black women who have established home-based bed and breakfasts and formed connections with white Europeans and South Africans during their entrepreneurial journeys. Employing Bourdieu’s theory of capital, I discuss how these entrepreneurs develop ties with whites to acquire social, economic, cultural, and symbolic forms of capital that have been systemically denied to them as black South African women. The interracial transference of these resources underscores the deep inequalities between blacks and whites, but also the agency of marginalized entrepreneurs to attain assets within constricting social structures.     

Gender identity and integration: second-generation Somali immigrants navigating gender in Canada

Many right-leaning politicians claim that normative Islamic perspectives on gender are at odds with the Western values and act as barriers to immigrant integration. Our interviews with 256 second-generation Somali-Canadians, however, suggest that gender-egalitarian identities are achieved – they are constructed and deployed by our participants to practice integration and express belonging in Canada. In this study, we move beyond analysis of attaining gender-egalitarian roles as a result of immigration and propose an understanding of gender as a form of Bourdieusian cultural capital that, depending on social values, functions as symbolic capital rendering individuals and groups as advantaged or disadvantaged. We, therefore, analyse modalities of “doing” gender as potential strategies of accumulating capital in furthering successful integration. Our study contributes to the emergent literature in migration studies that examines gender in relation to ethnic and national identities, and the extent to which it may impact integration experiences of second-generation Muslim immigrants.     

Constructions of race: symbolic ethnic capital and the performance of youth identity in multicultural Australia

The relationship between ethnicity and cultural and social capital has been taken up by several scholars in terms of questions of disadvantage. This paper considers the performance of race and ethnicity as positive capital among a group of Sudanese young people with refugee backgrounds in Brisbane, Australia. Based on ethnographic fieldwork, I demonstrate young people's adaptation of cultural associations in their hybridized and essentialized self-representations. In particular, I explore my informants’ use of hip hop music and style as resources in performance. Much of young people's engagement with capital in performance enables their relatively overt and self-conscious process of clarifying who they are in relationship to one another, often with particular reference to race and ethnicity. Their engagement with globally relevant mediums is indicative of young people's agency in defining their own lives in the context of the political and moral framework of Australian multiculturalism.     

Social capital and music teacher professional development: Principle,policy, and practice

Teacher professional development (PD) is often extended as a driver of good teaching and effective schools. In recent years, teacher PD has increasingly focused on developing teacher social capital by placing teachers within professional communities to collectively solve instructional problems. Using Bourdieu's and Coleman's conceptions of social capital as a theoretical and practical lens, this article explores how a social capital frame could generate more effective PD policy in music education. Areas examined also include the specific ways in which social capital becomes a lever for teacher growth and school improvement and the social dimensions of music teacher PD. The article concludes with principles of social capital-advancing PD policy, examples of principle-aligned PD policies, implications for research and advocacy, and an accounting of challenges and opportunities for the future. The author argues that centralizing social capital development as an aim of PD represents a new frontier in music teacher learning.     

Patterns of co-occurrence among arboreal marsupials in the forests of central Victoria,southeastern Australia

Abstract Patterns of co-occurrence were examined among the suite of species of arboreal marsupials that inhabit the montane ash forests of the Central Highlands of Victoria, southeastern Australia. The data used in our analyses were counts of different species of arboreal marsupials derived from stagwatching surveys of 152 sites throughout the Central Highlands region. Our work investigated both the number of species that tend to occur together, as well as identity of the taxa in such associations. A total of eight different species of arboreal marsupials were recorded from field surveys of montane ash forests: Leadbeater's Possum (Gymnobelideus leadbeateri), Sugar Glider (Petaurus breviceps), Yellow-bellied Glider (Petaurus australis), Greater Glider (Petauroides volans), Mountain Brushtail Possum (Trichosurus caninus), Feathertail Glider (Acrobates pygmaeus), Common Ringtail Possum (Pseudocheirusperegrinus), and Eastern Pygmy Possum (Cercartetus nanus). Large assemblages of taxa were rare and no sites supported the full array of species of arboreal marsupials– the maximum number of species recorded on a given 3 ha site was five. The results of our analyses indicated that if any one species of arboreal marsupials was present at a site, then on average 1. 5 other taxa will co-inhabit that site. The exception was the Common Ringtail Possum. When this species was detected, few other arboreal marsupial taxa tended to be recorded with it. Principal Co-ordinates Analysis showed that although combinations of animals comprised of either Mountain Brushtail Possum, Leadbeater's Possum, or Greater Glider were often recorded, there were no strong patterns in the identities of co-occurring taxa. This finding, together with the result that most taxa in these forests typically co-occurred with one or two other species, indicates that none of the arboreal marsupials inhabiting the montane ash forests of the Central Highlands of Victoria would be a good surrogate for (or ‘indicator’ of), the presence of the suite of other species in the assemblage.     

Beyond existence and aiming outside the laboratory: estimating frequency-dependent and pay-off-biased social learning strategies

The existence of social learning has been confirmed in diverse taxa, from apes to guppies. In order to advance our understanding of the consequences of social transmission and evolution of behaviour, however, we require statistical tools that can distinguish among diverse social learning strategies. In this paper, we advance two main ideas. First, social learning is diverse, in the sense that individuals can take advantage of different kinds of information and combine them in different ways. Examining learning strategies for different information conditions illuminates the more detailed design of social learning. We construct and analyse an evolutionary model of diverse social learning heuristics, in order to generate predictions and illustrate the impact of design differences on an organism's fitness. Second, in order to eventually escape the laboratory and apply social learning models to natural behaviour, we require statistical methods that do not depend upon tight experimental control. Therefore, we examine strategic social learning in an experimental setting in which the social information itself is endogenous to the experimental group, as it is in natural settings. We develop statistical models for distinguishing among different strategic uses of social information. The experimental data strongly suggest that most participants employ a hierarchical strategy that uses both average observed pay-offs of options as well as frequency information, the same model predicted by our evolutionary analysis to dominate a wide range of conditions.     

Dispossession, degradation and extinction: environmental history in arid Australia

Among the most popular media images of Australia are the outback heroes: the explorer, pioneer and pastoralist. However, there is insufficient attention paid to the role that pastoralists and their management strategies have played in the dispossession and degradation of arid Australia. A historical overview of ecology and land management suggests that the fragility of Australia's arid ecosystems was identified over 100 years ago, and despite repeated calls for reform, effective regional management schemes are still vehemently opposed by pastoralists. I argue that, until the role played by pastoralists and their management strategies in the degradation of arid Australia has been adequately communicated, pastoralists will remain a powerful political lobby capable of thwarting the implementation of sustainable land management practises.     

Managing the water of the Border Rivers in Australia: irrigation,Government and the wetland environment

Humans remove considerable amounts of water from rivers in Australia's Murray-Darling Basin. As a result, many wetlands no longer flood for as long or as frequently as they used to. Even though the extent of ecological damage is becoming better understood, the policies which contributed to increased water use are not well known. The Border Rivers Region of Australia provides an opportunity to more closely examine these issues. Water use rose by more than 2,700% between 1969 and 1991, mostly to irrigate cotton crops. Between 1969 and 1984, only about 5% of the water, measured at Goondiwindi on the main river channel of the Macintyre River, was used for irrigation. Water use to irrigate cotton increased to 60–69% of this measure in the period 1992–1995, which included two extremely dry years. This development was driven primarily by Governments through building dams. The ecological and economic costs of such changes were never adequately measured or forecasted. The key question for the future is whether Government should insist on proponents paying these costs or continue to promote and build infrastructure for water resource developments. Whatever the verdict, there must be better recognition of the economic and ecological costs through transparent processes of environmental assessment. This includes the economic benefits of riverine and wetland conservation. In addition, governmental environment protection and conservation agencies should participate more fully in decisions of water resource management if there is to be balance between resource exploitation and protection.     

The economic returns of bonding and bridging social capital for immigrant men in Germany

Using longitudinal data, this paper analyses the effect of different forms of social capital on the likelihood of employment and the occupational status of first generation immigrant men in Germany. This allows me to examine to what extent social capital of the bonding and the bridging types yield different returns. The study considers how contacts with natives, co-ethnic ties and family-based social capital are beneficial to the economic position of immigrant men. Random effects and fixed effects models show that strong inter-ethnic ties are beneficial both for employment and occupational status. There is no effect of co-ethnic ties and family-based social capital. It is concluded that, when using panel data, bridging social capital contributes to a better economic position and bonding social capital does not.     

Levelling the playing field: patterns of ethnic philanthropy among Los Angeles' middle- and upper-class Latino entrepreneurs

This paper examines whether middle- and upper-class Latino entrepreneurs retain a sense of ethnic solidarity expressed through community giving that is aimed at promoting the mobility of co-ethnics. I find that middle-class Latino entrepreneurs engage in more unstructured philanthropic activities, such as volunteering their time at Latino-centric organizations or mentoring low-income Latinos. In contrast, elite Latino entrepreneurs are creating ethnic social structures that focus on education and Latino business development.     

Social circulation and consumption of breast cancer health information among Yamatji in Western Australia

Breast cancer is one of the most common cancers in Australia, and other parts of the world, especially for women. Over the last few decades, more and more information has become available to the public about breast cancer. Throughout Yamatji country various formats for the dissemination of this information have been implemented, with varying degrees of success. Data collected as part of a doctoral research project on Yamatji breast cancer experiences shows that for information to be considered trustworthy and valid, it needs to be passed along social pathways that allow information ‘consumers’ to evaluate the information ‘provider’. Through this social circulation of health information, Yamatji actively engage and shape health information provision, as well as distribution. Likewise, by rejecting certain health information as untrustworthy, Yamatji assert agency in their self‐health management.     

Sick Again,Well Again: Sorcery,Christianity and Kinship in Northern Aboriginal Australia

This article concerns the ways in which Yolngu people of the Galiwin'ku settlement in northern Australia employ contemporary constructions of sorcery doctrines and Christian practices to rearticulate their kinship relations. In particular, I discuss the adaptation of sorcery ideas and accusations to present-day circumstances and the Christian healing processes that have emerged alongside traditional healing behaviours and biomedicine. Sorcery and Christianity at Galiwin'ku, I argue, are intertwined ethical models that enable the person and community to heal over and over again in accordance with the vicissitudes of postcolonial life. They continue the moral imperative of ‘looking after’ kin even as the net of ‘looking after’ has expanded to encompass new experiences, behaviours, and persons.
