Applying a critical heritage studies approach to plants, this article explores how plant knowledge and use, plant exchange, and plant symbolism and materiality feature in the social life of the dispersed Chagossian community in Mauritius, Seychelles, and the UK. First, plant use helps to sustain collective knowledge in new environmental conditions and social settings. Second, plant exchange nourishes kinship and other social relationships within the extended community. Third, plant symbolism and materiality cultivate nostalgic links to idealized homelands in the context of community dispersal. Nevertheless, the capacity of plants to contribute to these social processes is limited by challenges to intergenerational knowledge transmission across time and space, and by environmental, financial, and regulatory constraints on plant migration. The article argues that for the displaced Chagossian community, plants are living cultural heritage with social potential (albeit constrained) in the context of dislocation and loss, ongoing suffering, and geographical dispersal.  相似文献

Genes shared through common ancestry are among the oldest social bonds. Despite these ancient roots, humans often co-opt the psychology of genetic relatedness and extend it to genetically unrelated others through culturally-acquired kinship systems. We investigate how genealogical relatedness and kinship norms might mutually support or oppose each other within a known kin network in Yasawa, Fiji. Yasawans' reliance on intensive, kin-based cooperation for daily life makes Yasawan kinship an interesting test case to compare the effects of genealogy and kinship norms. Confirming qualitative ethnographic claims, we find that Yasawan kin terms can be described in two dimensions of respect/closeness and joking/authority. Individual players use different strategies for genealogical relatives and non-relatives by making economic game choices that are increasingly beneficial to partners who share a higher percentage of genes through common ancestry. However, pairs of players are most successful in coordinating their game choices despite conflicting self-interests based upon kinship norms relevant to hierarchy. Thus, while genealogical relatedness may boost generosity, the extra behavioral structuring from kinship norms facilitates more productive but difficult coordinated action even when communication is not possible.  相似文献

In many primates, close social relationships are associated with lower stress, better health, and increased life span. However, individuals do not form bonds indiscriminately; rather, they focus on a few primary partners. This suggests that the identity of the partner may be as important as the bond itself. Although dominance and kinship have repeatedly emerged as salient predictors of female relationships, most of this research comes from species with multimale, multifemale groups and strict dominance hierarchies. Further, kinship was typically determined based on either behavior or on known mother–daughter relationships alone. To understand the generality of previous findings, we use behavioral and genetic sampling to examine whether dominance rank and/or genetic relatedness mediate female social bonds in geladas (Theropithecus gelada) living in the Simien Mountains National Park, Ethiopia. First, we found that, even though females in the same unit are closely related, female geladas still preferentially bond with the closest of these relatives. Second, females that were close kin formed the strongest bonds with females of similar rank to themselves. Finally, rank disparity predicted grooming rates but did not predict whether females were nearest neighbors. This suggests that, in contrast with data from other cercopithecines, spatial proximity among females may be less indicative of strong social bonds for geladas, a species that routinely exhibits a high degree of spatial overlap with extra-unit individuals. Together, these results highlight the importance of combining genetic data with detailed behavioral observations to help us understand how individuals choose and interact with social partners.  相似文献

Comparative studies of the health, well-being, and social functioning of adolescents and youths have, in the past two decades, been focused on young people in developing countries where rapid social, cultural, and economic changes have been associated with dramatic increases in the rates of social problems indicative of poorer mental health. Young people in many Pacific Island societies suffer from some of the highest rates of social problems like suicide and substance abuse in the world. It is generally agreed that the increases in rates of social problems among youths in this region result from increases in psychosocial stress, anger, and frustration surrounding intergenerational conflict within the family. Much less is known about the aspects of everyday experiences of young people in the Pacific that can lead to psychosocial stress and the angry episodes of interpersonal conflict that often precede suicide attempts and binge drinking. This paper examines 40 cases of interpersonal conflict in young men's and women's experiences in the islands of Chuuk of the Federated States of Micronesia to better understand what can lead to elevated levels of psychosocial stress for youths in the Pacific. This study shows that the emotional crises of young people in Chuuk often emerge from the incongruence in their pursuit of valued personal and social identities within the family, the community, and the peer group. Thus youths who experience more incongruity in their engagements across the multiple activity settings of everyday life are at greater risk for stressful experiences.  相似文献

A growing body of evidence shows within-population variation in natal dispersal, but the effects of such variation on social relationships and the kin composition of groups remain poorly understood. We investigate the link between dispersal, the kin composition of groups, and proximity patterns in a population of black-and-white colobus (Colobus vellerosus) that shows variation in female dispersal. From 2006 to 2011, we collected behavioral data, demographic data, and fecal samples of 77 males and 92 females residing in eight groups at Boabeng-Fiema, Ghana. A combination of demographic data and a genetic network analysis showed that although philopatry was female-biased, only about half of the females resided in their natal groups. Only one group contained female-female dyads with higher average relatedness than randomly drawn animals of both sexes from the same group. Despite between-group variation in female dispersal and kin composition, female-female dyads in most of the study groups had higher proximity scores than randomly drawn dyads from the same group. We conclude that groups fall along a continuum from female dispersed, not kin-based, and not bonded to female philopatric, kin-based, and bonded. We found only partial support for the predicted link between dispersal, kin composition, and social relationships. In contrast to most mammals where the kin composition of groups is a good predictor of the quality of female-female relationships, this study provides further support for the notion that kinship is not necessary for the development and maintenance of social bonds in some gregarious species.  相似文献

For individualization of a biomechanical model, it is necessary to estimate the muscle attachments of the person to whom it is to be adapted. One of the methods to estimate muscle attachments is to use model transformations to transform a model with known muscle attachments to the bones of a person. We hypothesize that the location and shape of muscle attachment sites correlate with the shape of the bones they are attached to. If this hypothesis holds, it is possible to predict the location of muscle attachments when the shape of the bones is known. To validate this hypothesis, geometric models of three sets of shoulder bones were built. These models consist of 3-D surface models of the scapula, clavicle, and humerus, with the muscle attachment contours connected to them. By means of geometric transformations, the models were transformed, so the muscle attachments of the different data sets could be compared. Using these techniques, 50 per cent of the muscle attachment contours could be predicted with high accuracy. The muscle attachment contours that could not be predicted were all influenced by measurement errors. For 30 per cent of the muscle attachment contours, it was not possible to distinguish the interindividual differences from the inaccuracies of the method used. From this study, we concluded that most muscle attachment contours can be predicted by means of geometric models of the bones.  相似文献

Laboratory models have suggested a link between metabolism and life span in vertebrates, and it is well known that the evolution of specific life histories can be driven by metabolic factors. However, little is known regarding how the adoption of specific life-history strategies can shape aging and life span in populations facing different energetic demands from either a theoretical or a mechanistic viewpoint but significant insight can be gained by using a comparative approach. Comparative biology plays several roles in our understanding of the virtually ubiquitous phenomenon of aging in animals. First, it provides a critical evaluation of broad hypotheses concerning the evolutionary forces underlying the modulation of aging rate. Second, it suggests mechanistic hypotheses about processes of aging. Third, it illuminates particularly informative species because of their exceptionally slow or rapid aging rates to be interrogated about potentially novel mechanisms of aging. Although comparative biology has played a significant role in research on aging for more than a century, the new comparative biology of aging is poised to dwarf those earlier contributions, because: (1) new cellular and molecular techniques for investigating novel species are in place and more are being continually generated, (2) molecular systematics has resolved the phylogenetic relationships among a wide range of species, which allow for the implementation of analytic tools specialized for comparative biology, and (3) in addition to facilitating the construction of accurate phylogenies, the dramatic acceleration in DNA-sequencing technology is providing us with new tools for a comparative genomic approach to understanding aging.  相似文献

Altruism poses a problem for evolutionary biologists because natural selection is not expected to favor behaviors that are beneficial to recipients, but costly to actors. The theory of kin selection, first articulated by Hamilton (1964), provides a solution to the problem. Hamilton's well-known rule (br > c) provides a simple algorithm for the evolution of altruism via kin selection. Because kin recognition is a crucial requirement of kin selection, it is important to know whether and how primates can recognize their relatives. While conventional wisdom has been that primates can recognize maternal kin, but not paternal kin, this view is being challenged by new findings. The ability to recognize kin implies that kin selection may shape altruistic behavior in primate groups. I focus on two cases in which kin selection is tightly woven into the fabric of social life. For female baboons, macaques, and vervets maternal kinship is an important axis of social networks, coalitionary activity, and dominance relationships. Detailed studies of the patterning of altruistic interactions within these species illustrate the extent and limits of nepotism in their social lives. Carefully integrated analyses of behavior, demography, and genetics among red howlers provide an independent example of how kin selection shapes social organization and behavior. In red howlers, kin bonds shape the life histories and reproductive performance of both males and female. The two cases demonstrate that kin selection can be a powerful source of altruistic activity within primate groups. However, to fully assess the role of kin selection in primate groups, we need more information about the effects of kinship on the patterning of behavior across the Primates and accurate information about paternal kin relationships.  相似文献

Genetic tools are increasingly valuable for understanding the behaviour, evolution, and conservation of social species. In African elephants, for instance, genetic data provide basic information on the population genetic causes and consequences of social behaviour, and how human activities alter elephants' social and genetic structures. As such, African elephants provide a useful case study to understand the relationships between social behaviour and population genetic structure in a conservation framework. Here, we review three areas where genetic methods have made important contributions to elephant behavioural ecology and conservation: (1) understanding kin-based relationships in females and the effects of poaching on the adaptive value of elephant relationships, (2) understanding patterns of paternity in elephants and how poaching can alter these patterns, and (3) conservation genetic tools to census elusive populations, track ivory, and understand the behavioural ecology of crop-raiding. By comparing studies from populations that have experienced a range of poaching intensities, we find that human activities have a large effect on elephant behaviour and genetic structure. Poaching disrupts kin-based association patterns, decreases the quality of elephant social relationships, and increases male reproductive skew, with important consequences for population health and the maintenance of genetic diversity. In addition, we find that genetic tools to census populations or gather forensic information are almost always more accurate than non-genetic alternatives. These results contribute to a growing understanding of poaching on animal behaviour, and how genetic tools can be used to understand and conserve social species.  相似文献

This article explores the social reproduction of 'corruption' in Nigeria, using ethnographic data collected in the Igbo-speaking southeast. The author argues that corruption must be understood in the context of everyday instances of patronage as they occur in networks of kin, community, and interpersonal association. Kinship relationships, and other social ties rooted in similar moral obligations and affective attachments, enable Igbos to navigate Nigeria's clientelistic political economy. They also serve to perpetuate an ethic of appropriate redistribution that fuels corruption. The article analyzes a deep-seated ambivalence that is created as the reciprocal obligations of kinship articulate with structures of power and inequality that characterize contemporary Nigeria. Rather than withering away as Nigeria modernizes, the instrumental importance of kinship and community of origin may be greater than ever.  相似文献

Cultural consonance is the degree to which individuals, in their own beliefs and behaviors, approximate widely shared cultural models. In previous research in Brazil and the United States we found that higher cultural consonance in the cultural domains of lifestyle and social support was associated with lower psychological distress. The aim of this paper is to expand on these results in two ways. First, the measurement of cultural consonance has been improved through a closer link of cultural domain analyses and survey research. Second, the number of domains in which cultural consonance has been examined has been expanded to include—along with lifestyle and social support—family life, national identity, and food. We found that cultural consonance in these five domains can be conceptualized as two latent variables of generalized cultural consonance, and that this generalized cultural consonance is associated with lower psychological distress. These results continue to support the usefulness of cultural consonance as a theoretical construct in the explanation of human social suffering.  相似文献

In post-Soviet Cuba, instead of the political future envisioned by Revolutionary authorities, poor residents of Havana aspire to create kinship futures where there is no need to ‘sleep alone’. Here, the idea of ‘sleeping together’ represents a trustworthy social bond that shelters a person from loneliness over time. For these habaneros, sexual love between men and women cannot be trusted, since it is often plagued by suspicions of material interest. By contrast, they view parent-child connections as a way to secure a cared-for future for themselves. Nevertheless, as Cuban socialism undergoes transformations, gendered inequalities create obstacles for many people's aspirations for parenthood. This article explores the contrast between sexual and filial love in Cubans’ efforts to create kinship futures for themselves, thereby adding to our understandings of poor people's life projects.  相似文献

ABSTRACT

This article synthesizes foundational knowledge from multiple scientific disciplines regarding how humans develop in context. Major constructs that define human development are integrated into a developmental system framework, this includes—epigenetics, neural malleability and plasticity, integrated complex skill development and learning, human variability, relationships and attachment, self-regulation, science of learning, and dynamics of stress, adversity and resilience. Specific attention is given to relational patterns, attunement, cognitive flexibility, executive function, working memory, sociocultural context, constructive development, self-organization, dynamic skill development, neural integration, relational pattern making, and adverse childhood experiences. A companion article focuses on individual-context relations, including the role of human relationships as key drivers of development, how social and cultural contexts support and/or undermine individual development, and the dynamic, idiographic developmental pathways that result from mutually influential individual-context relations across the life span. An understanding of the holistic, self-constructive character of development and interconnectedness between individuals and their physical, social, and cultural contexts offers a transformational opportunity to study and influence the children’s trajectories. Woven throughout is the convergence of the science of learning – constructive developmental web, foundational skills, mindsets (sense of belonging, self-efficacy, and growth mindset), prior knowledge and experience, motivational systems (intrinsic motivation, achievement motivation, and the Belief-Control-Expectancy Framework), metacognition, conditions for learning , cultural responsiveness and competence, and instructional and curricular design- and its importance in supporting in integrative framework for children’s development. This scientific understanding of development opens pathways for new, creative approaches that have the potential to solve seemingly intractable learning and social problems.  相似文献

This paper presents a comparison of social kinship (patrilineage) and biological kinship (genetic relatedness) in predicting cooperative relationships in two different economic contexts in the fishing and whaling village of Lamalera, Indonesia. A previous analysis (Alvard, Human Nature 14:129-163, 2003) of boat crew affiliation data collected in the village in 1999 found that social kinship (patrilineage) was a better predictor of crew affiliation than was genetic kinship. A replication of this analysis using similar data collected in 2006 finds the same pattern: lineage is a better predictor than genetic kinship of crew affiliation, and the two together explain little additional variance over that explained by lineage alone. However, an analogous test on food-sharing relationships finds the opposite pattern: biological kinship is a better predictor of food-sharing relationships than is social kinship. The difference between these two cooperative contexts is interpreted in terms of kin preferences that shape partner choice, and the relative autonomy with which individuals can seek to satisfy those preferences. Drawing on stable matching theory, it is suggested that unilineal descent may serve as a stable compromise among multiple individuals' incongruent partner preferences, with patriliny favored over matriliny in the crew-formation context because it leads to higher mean degrees of relatedness among male cooperators. In the context of food-sharing, kin preferences can be pursued relatively autonomously, without the necessity of coordinating preferences with those of other households through the institution of lineage.  相似文献

This paper shows that the Huaorani Indians of the Ecuadorian Amazon possess a long-standing common property management regime fostered by secure ownership status of the land, the small size and kinship ties of residence groups, the existence of mutual trust and reciprocity, and culturally sanctioned rules of behavior. This regime, however, was focused on maintaining harmonious relationships between residents of the nanicabo and not on resource conservation (although it may have fostered epiphenomenal conservation). It cannot be presumed that communal management of resources invariably leads to conservation; other factors need to be present, such as a perception of resource scarcity. The common property regime was designed for a situation of plentiful resources, low population density, clear membership, and behaviors held in check by respect for kin and the desire for good standing. It was a sufficient and simple system for delimiting common property resources from private property, based on implicit social boundaries and cultural understandings. Now, confronted by powerful external forces, population growth, and intermarriage with non-Huaorani, the system is faltering. Conservationist practices, however, can be encouraged by adapting the earlier system to reflect current conditions.  相似文献

This paper focuses on technologies for assisting conception and considers how normative notions of conception and family formation have informed the rejection, incorporation and adaptation of technologies and their regulation in New Zealand. Drawing on a textual analysis of primary written materials and secondary sources generated between 1965 and 2004, the paper reveals how these technologies help various groups in New Zealand society make explicit their understandings of relatedness, identity and social and cultural belonging. Whilst biological/genetic connection and social connections inform understandings of kinship, reproduction, parenthood and social structure for many New Zealanders, the boundaries between the biological and social are often blurred and precedence of one over the other is very much context dependent. The incorporation of the new reproductive technologies has been an inherently politicised process, with barriers to access to these technologies emerging in relation to ethnic identity and race, sexuality, socioeconomic status, gender, and marital status.  相似文献

This paper critically analyses from a political sociology standpoint the international conceptualization of war-affected populations as traumatized and in need of therapeutic interventions. It argues for the importance of looking beyond the epidemiological literature to understand trauma responses globally. The paper explores how the imperative for international psychosocial programmes lies in developments within donor countries and debates in their humanitarian sectors over the efficacy of traditional aid responses. The aim of the paper is threefold. First, it discusses the emotional norms of donor states, highlighting the psychologizing of social issues and the cultural expectations of individual vulnerability. Second it examines the demoralization of humanitarianism in the 1990s and how this facilitated the rise of international psychosocial work and the psychologizing of war. Third, it draws attention to the limitations of a mental health model in Croatia, a country which has been receptive to international psychosocial programmes. Finally it concludes that the prevalent trauma approaches may inhibit recovery and argues for the need to re-moralize resilience.  相似文献

The human ability to form large, coordinated groups is among our most impressive social adaptations. Larger groups facilitate synergistic economies of scale for cooperative breeding, such economic tasks as group hunting, and success in conflict with other groups. In many organisms, genetic relationships provide the structure for sociality to evolve via the process of kin selection, and this is the case, to a certain extent, for humans. But assortment by genetic affiliation is not the only mechanism that can bring people together. Affinity based on symbolically mediated and socially constructed identity, or cultural kinship, structures much of human ultrasociality. This paper examines how genetic kinship and two kinds of cultural kinship--affinal kinship and descent--structure the network of cooperating whale hunters in the village of Lamalera, Indonesia. Social network analyses show that each mechanism of assortment produces characteristic networks of different sizes, each more or less conducive to the task of hunting whales. Assortment via close genetic kin relationships (r?=?0.5) produces a smaller, denser network. Assortment via less-close kin relations (r?=?0.125) produces a larger but less dense network. Affinal networks are small and diffuse; lineage networks are larger, discrete, and very dense. The roles that genetic and cultural kinship play for structuring human sociality is discussed in the context of these results.  相似文献

Pediatric genetics is growing in significance as a tool to explain childhood illness and disability. Within both medical sociology and anthropology writers have explored whether investigating genetic inheritance can overemphasize biological connection over other versions of kinship and can also lead to new forms of responsibility being imposed on parents for being “guilty” of sharing problematic “substance” with their offspring. Such considerations are complicated by the fact that a child's genetic variation is not necessarily something they inherited from their parents. This paper explores how questions of inheritance and responsibility are brought into play by pediatric genetics. It does so by drawing on ethnographic research of a genetics service in the UK. In particular we highlight how understandings of kinship can be unsettled by genetic scrutiny, but that once unsettled are not resolved by establishing whether a child has or has not inherited a genetic condition from their parents. Instead existing cultural kinship understandings of the moral substance of kinship responsibility towards producing and raising the right kinds of children are of equal (if not more) importance.  相似文献
