Ethnographic films hold great historical value for the communities in which they were filmed, yet people in source communities often lack access to them. Visitors engaging in ‘visual repatriation’ of ethnographic film can enrich both sides of the ethnographic exchange. I review my experiences screening ethnographic films with Trobriand Islanders, their reactions, and the various ways in which local communities regain ownership of these films, including re‐narration and renaming. My findings reiterate how source communities' reception of, and uses for, ethnographic film can sharply differ from the filmmakers' original agenda.  相似文献

ABSTRACT

When tourists visit cultural tourism destinations, the primary form of interaction between visitors and local residents is in the exchange of money for material objects and performances. While purchase of cultural commodities in tourism contexts may appear to be simple market transactions, they are often in fact morally fraught sites of ambiguous interaction, invested with disparate meanings by different participants. Drawing on Bloch and Parry's (1989 Bloch, Maurice. 1989. The symbolism of money in Imerina. In Money and the Morality of Exchange, edited by J. Parry & M. Bloch. pp. 165–190. Cambridge: Cambridge University Press. [Google Scholar]) analysis of the symbolism of money and its relationship to culturally constructed ideas about production, consumption, circulation, and exchange, this article examines the conflicting and contested views of cash transactions and other types of exchange in meetings between tourists and Trobriand Islanders in Papua New Guinea. I argue that intercultural exchange in tourism is not necessarily a straightforward commodity exchange, but evokes social relations that are often quite differently conceptualized by the producers and consumers of touristic products.  相似文献

Avian co-operative breeders show a diverse range of social and reproductive systems. Here we combined microsatellite genotyping with field observations over three consecutive breeding seasons to investigate the social structure and mating system of the White-breasted Thrasher Ramphocinclus brachyurus . Co-operative breeding was facultative in this species, with approximately one-third of nests having helpers. Breeding groups comprised a pair of breeding adults and up to three helpers of either sex. Within co-operative groups, age was associated with parentage in both sexes. Helpers were retained offspring and either rarely or never achieved parentage in current broods. There was no evidence of egg dumping and a relatively small percentage of chicks (7.5%, n  = 67) were fathered by males from outside the co-operative group. The White-breasted Thrasher is a globally Endangered species with a very small and declining population. A captive breeding programme for this species is not recommended at present, but may become necessary in the future, and any such programme should take account of our findings regarding breeding behaviour and group structure.  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

To overcome limitations of diversity measures applied to livestock breeds marker based estimations of kinship within and between populations were proposed. This concept was extended from the single locus consideration to chromosomal segments of a given length in Morgan. Algorithms for the derivation of haplotype kinship were suggested and the behaviour of marker based haplotype kinship was investigated theoretically. In the present study the results of the first practical application of this concept are presented. Full sib pairs of three sub-populations of the Goettingen minipig were genotyped for six chromosome segments. After haplotype reconstruction the haplotypes were compared and mean haplotype kinships were estimated within and between populations. Based on haplotype kinships a distance measure is proposed which is approximatively linear with the number of generations since fission. The haplotype kinship distances, the respective standard errors and the pedigree-based expected values are presented and are shown to reflect the true population history better than distances based on single-locus kinships. However the marker estimated haplotype kinship reveals variable among segments. This leads to high standard errors of the respective distances. Possible reasons for this phenomenon are discussed and a pedigree-based approach to correct for identical haplotypes which are not identical by descent is proposed.  相似文献

Rhizophora stylosa is an ecologically important mangrove tree species that is found in tropical and subtropical regions. We isolated five polymorphic microsatellite loci from R. stylosa using a dual‐suppression‐polymerase chain reaction technique. These loci provided microsatellite markers with polymorphism of four alleles in each locus for overall population. The mean expected heterozygosities ranged from 0.113 to 0.473.  相似文献

The islands of French Polynesia cover an area the size of Europe, though total land area is smaller than Rhode Island. Each hot spot archipelago (Societies, Marquesas, Australs) is chronologically arranged. With the advent of molecular techniques, relatively precise estimations of timing and source of colonization have become feasible. We compile data for the region, first examining colonization (some lineages dispersed from the west, others from the east). Within archipelagos, blackflies (Simulium) provide the best example of adaptive radiation in the Societies, though a similar radiation occurs in weevils (Rhyncogonus). Both lineages indicate that Tahiti hosts the highest diversity. The more remote Marquesas show clear examples of adaptive radiation in birds, arthropods and snails. The Austral Islands, though generally depauperate, host astonishing diversity on the single island of Rapa, while lineages on other islands are generally widespread but with large genetic distances between islands. More recent human colonization has changed the face of Polynesian biogeography. Molecular markers highlight the rapidity of Polynesian human (plus commensal) migrations and the importance of admixture from other populations during the period of prehistoric human voyages. However, recent increase in traffic has brought many new, invasive species to the region, with the future of the indigenous biota uncertain.  相似文献

Genetic parentage analyses provide a practical means with which to identify parent–offspring relationships in the wild. In Harrison et al.'s study (2013a), we compare three methods of parentage analysis and showed that the number and diversity of microsatellite loci were the most important factors defining the accuracy of assignments. Our simulations revealed that an exclusion‐Bayes theorem method was more susceptible to false‐positive and false‐negative assignments than other methods tested. Here, we analyse and discuss the trade‐off between type I and type II errors in parentage analyses. We show that controlling for false‐positive assignments, without reporting type II errors, can be misleading. Our findings illustrate the need to estimate and report both the rate of false‐positive and false‐negative assignments in parentage analyses.  相似文献

The effect of kinship on growth and growth variability was studied by rearing young-of-the-year Arctic charr in full-sibling, mixed-sibling or non-kin groups for 11 weeks. Both weight and length were found to be significantly greater among full-sibling v. mixed or non-kin groups. Also, variance in weight and length of the individuals within groups was found to be significantly lower in full-sibling v. mixed or non-kin groups. These data suggest that relatedness of group members has a significant effect on both the growth rate and variation in growth of juvenile Arctic charr.  相似文献

Captive studies can make a unique contribution to primate socioecology by documenting species-typical social dispositions under controlled conditions. Recent theories seek to connect the dominance relationships, group cohesiveness, and feeding ecology of primates. The present study explores the first two aspects by comparing the social organization of rhesus (Macaca mulatta) and stumptail monkeys (M. arctoides). Data were collected over a period of eight years, with five different methods, on three well-established captive groups in identical environments. The groups were found to share one characteristic: a clear-cut, linear formal dominance hierarchy as expressed in teeth-baring displays. The two main study groups (one of each species) differed significantly, however, with respect to nine of eleven behavioral measures. In addition to a previously reported higher frequency of reconciliation in the stumptail group, this group showed (1) more frequent but less severe aggressive behavior, (2) greater symmetry of contests, (3) greater social tolerance, (4) more nonagonistic approaches, and (5) more allogrooming. The differences can be summarized as a contrast in dominance “style,” with the stumptails having a more relaxed style and placing greater emphasis on social cohesion than the rhesus monkeys. An egalitarian attitude was also reflected in approach behavior: contacts in the rhesus group were mostly initiated by dominants, whereas contacts in the stumptail group were initiated independent of rank. Comparisons with a second rhesus group, and with published reports, suggest that while some of the observed differences are probably representative of the two species, considerable intraspecific variation does exist, and a more comprehensive program of comparative studies is needed.  相似文献

In a studbook, MULT is used in a parent ID field when the actual parent is unknown but the parent is known to be one of a set of possible parents. Probabilities of being the actual parent are assigned to each possible parent in the MULT group, and that information is used in the calculation of mean kinships (MKs). Parental probabilities are typically assigned based on the species biology and/or what was known about how the animals were being managed at the time of conception. If there is no additional information, the default is to assign each possible parent the same probability. What has not been considered to date is the impact of different MKs among the group of possible parents. Methods are developed which allow a combination of parental probabilities and MKs into parental weights. These weights replace parental probabilities in the analysis. One important conclusion is that even when the MKs of possible parents are quite different, the difference between the parental weights and probabilities is typically less than 30%. This highlights the importance of correct estimation of parental probabilities, whenever possible, instead of reliance on a default.  相似文献

The author comments on a recent article by Werner Cohn concerning the kinship terms among the North American Gypsies. He suggests that since pašo, meaning wife's sister's husband, is also found among the southern Slavs, it is highly probable that it is from them that the Gypsies took the term .  相似文献

The tendency in primates for former antagonists to approach and affiliate following aggression has been termed reconciliation because the response is thought to resolve social conflicts produced by aggression. In primate societies, however, an aggressive interaction between two individuals often spreads to include other group members, especially the kin of the combatants. If post conflict affiliation resolves aggressive conflicts in a group, then affiliative increases might occur between combatants and the kin of their opponents following aggression as well as between former opponents. This hypothesis was tested in a captive group of 39 pigtail macaques (Macaca nemestrina) by comparing affiliative response frequencies of combatants during the 5 minute period following aggression to affiliative response frequencies during 5 minute baseline periods not preceded by aggressive activity. Following aggression, affiliation rates increased between combatants and their opponents, aggressors and the kin of their opponents, and aggressors and their own kin. Additional analyses showed that aggression among kin was reconciled more often than aggression among nonkin. Recipients of aggression reconciled with their attackers more often than aggressors reconciled with their victims. Animals with similar dominance ranks reconciled proportionately more often than those with large rank disparities and aggressive infractions of a calculated dominance hierarchy were reconciled more often than attacks consistent with the hierarchy. Results suggest that both dyadic and triadic reconciliations occur in M. nemestrina and that compared to other primate species M. nemestrina exhibit a moderate-to-high conciliatory tendency.  相似文献

Petr Lom's film, Bride Kidnapping in Kyrgyzstan , offers viewers a striking visual narration of the deeply routinized practices of bride capture in contemporary Central Asia. In this review, I offer historical context eschewed by the film, observing how, contrary to popular belief, bride kidnapping increased under Russian imperial supervision. It later dwindled in the activist Soviet period, but rose again in the relative anarchy of the postsocialist landscape. What the film invites but does not explicitly entertain is a complex arithmetic of culturally coded understandings of volition, personal property, and alliance.  相似文献

Time‐trees are commonly calibrated based on fossils attributed to internal nodes, thus defining the minimum age of these nodes. However, in the absence of synapomorphies, the phylogenetic position of a fossil can only be inferred based on similarity. In this study, we objectively allocated fossil shells to internal nodes based on the reconstruction of ancestral shapes and sizes in a geometric morphometric framework. Our phylogenetic analysis of 24 (putative sub)species was based on 2524 amplified fragment length polymorphism loci. In this well‐supported tree the taxa occurring in north‐west Africa and on the Iberian peninsula were paraphyletic with respect to the (sub)species from the Canary and Selvagen Islands, indicating a continental origin of the genus in contrast to our earlier sequence‐based account. Ancestral shell shapes and sizes were inferred based on landmark data using squared‐change parsimony. In a subsequent principal component analysis, only three of 20 fossil shells could be unequivocally allocated to internal nodes. However, these fossils were all Quaternary, and thus too young to infer meaningfully narrow confidence intervals for divergence estimates that probably reach back into the Miocene or even Oligocene. The apparent failure of allocating older fossils to internal nodes and achieving a reliable tree calibration was caused by the absence of phylogenetic signal in the shells of Theba due to extensive, sometimes rapid, convergent evolution, including reversals. © 2014 The Linnean Society of London  相似文献

Isozyme analyses were conducted to study the geographic variation ofCapsicum frutescens L. in Southeast and East Asia, and to investigate its dispersal routes into Japan. Eight enzymes (EST, EM, G6PD, GR, ME(A), PGI, PGM, ShDH) were variable among accessions ofC. frutescens in Southeast and East Asia. Accessions from the Ryukyu Islands were closely related to those in Indonesia, whereas accessions from the Bonin Islands showed exactly the same isozyme patterns as those from Indonesia and Northern Thailand. Accessions in the Ryukyu Islands were different from those in the Bonin Islands, suggesting that there may be two independent dispersal routes into Japan. One route was from Indonesia via the Philippines or Taiwan, or directly to the Ryukyu Islands, and another was from Indonesia via the Mariana Islands, or other islands in the Pacific, to the Bonin Islands.  相似文献
