Researchers commonly use long-term average production inequalities to characterize cross-cultural patterns in foraging divisions of labor, but little is known about how the strategies of individuals shape such inequalities. Here, we explore the factors that lead to daily variation in how much men produce relative to women among Martu, contemporary foragers of the Western Desert of Australia. We analyze variation in foraging decisions on temporary foraging camps and find that the percentage of total camp production provided by each gender varies primarily as a function of men’s average bout successes with large, mobile prey. When men target large prey, either their success leads to a large proportional contribution to the daily harvest, or their failure results in no contribution. When both men and women target small reliable prey, production inequalities by gender are minimized. These results suggest that production inequalities among Martu emerge from stochastic variation in men’s foraging success on large prey measured against the backdrop of women’s consistent production of small, low-variance resources.

Rebecca Bliege Bird   received her Ph.D. from UC Davis in 1996. She is interested in gendered strategies of social and economic production, especially as they relate to altruism and public goods provisioning in prestige competitions. In pursuit of these and other questions related to the socioecology of subsistence, she has worked in Torres Strait among the Meriam and is currently working with Martu in Australia’s Western Desert. Brian F. Codding   received his B.S. from California Polytechnic State University, San Luis Obispo in 2005 and his M.A. in 2008 from Stanford University, where he is currently a Ph.D. student in the Department of Anthropology. His current research examines the social ecology of gender-specific foraging in archaeological and ethnographic contexts in California and Western Australia. Douglas W. Bird   received his Ph.D. from UC Davis in 1996. His interest in ethnoarchaeology led him to explore the processes of shellmidden formation among Meriam of the Torres Strait. He is currently investigating the politics of hunting among Martu and the way that sharing can, paradoxically, create social hierarchy.  相似文献

The study investigates traditional knowledge of forest plants in a community (La Quetzal) inhabited by people who returned to Guatemala at the end of the civil war, after 10–12 years in exile in Southern Mexico, and now are in the process of constructing a new community in the Lacandon jungle in the Petén, Guatemala. We ask if the basis of knowledge and the use of natural resources change when people migrate. The relevance of vascular plant diversity for consumption and other daily needs of the population is explored. Relatively few species are presently used, with the exception of timber species, where knowledge seems to be increasing. Traditional knowledge has been maintained in certain areas such as medicine. Nature as such is regarded as important primarily as potential monetary capital and not for its subsistence capital. We find that the refugee situation has led to the introduction of global consumption patterns. Still there continues to be a dynamic local intuitive knowledge arising directly from practical experiences. Two interlinked factors have been the driving forces altering the knowledge and the use of natural resources by the people in La Quetzal: Change in the natural environment and change in the social and economic environment.

This study of values placed on wildlife by Bantu and Yaka Pygmy forest dwellers (n = 200) in Northern Congo identified and analyzed two wildlife value orientations - “anthropocentric” and “biocentric.” The former, strongly displayed across all segments of both societies, was likely motivated by heavy reliance on bushmeat and human–wildlife conflicts, and was linked to attitudes approving the killing of animals for human benefit. The “biocentric” orientation was more common among formally educated male respondents who do not hunt and positively linked to attitudes favoring conservation. Wildlife management strategies should consider including 1) sustainable local wildlife exploitation, 2) livelihood projects that provide a real alternative to hunting, and 3) human–wildlife conflict mitigation.  相似文献

Hystrix Moench was a perennial genus of the Triticeae. Its members differed from those of other genera in the tribe in lacking glumes. The type species is H. patulaMoench, a North American taxon. When it became accepted that H. patula should be included in Elymus, Hystrix could not be used as a generic name. The problem became how to treat the other species that had been included in Hystrix. Hystrix patula, like many other species of Elymus, has the StH genomic composition but H. coreana (Honda) Ohwi, H. californica (Bol.) Kuntze, H. duthiei (Stapf) Bor ssp. duthiei, and H. duthiei ssp. longearistata have the NsXm genomic composition that is associated with Leymus. Using genomic in situ hybridization analysis, we showed that H. komarovii (Roshev.) Ohwi has an NsEe genomic composition, a combination not known from any other species. Hystrix sibirica (Trautv.) Kuntze and H. duthiei ssp. japonica are included in Leymus on morphological grounds. The status of H. kunlunensis K. S. Hao is not clear. In this paper, we summarize our results and those of others concerning what is now known and the problems that remain concerning the species that used to be included in Hystrix.  相似文献

Background

Low- to middle-income countries (LMICs) are believed to be characterized by the coexistence of underweight and overweight. It has also been posited that such coexistence is appearing among the low socioeconomic status (SES) groups.

Methods

We conducted a cross-sectional analysis of nationally representative samples of 451321 women aged 20–49 years drawn from 57 Demographic and Health Surveys conducted between 1994 and 2008. Body Mass Index (BMI in kg/m2), was used to define underweight and overweight following conventional cut-points. Covariates included age, household wealth, education, and residence. We estimated multinomial multilevel models to assess the extent to which underweight (BMI<18.5 kg/m2) and overweight (BMI≥25.0 kg/m2) correlate at the country-level, and at the neighborhood-level within each country.

Results

In age-adjusted models, there was a strong negative correlation between likelihood of being underweight and overweight at country- (r = −0.79, p<0.001), and at the neighborhood-level within countries (r = −0.51, P<0.001). Negative correlations ranging from −0.11 to −0.90 were observed in 46 of the 57 countries at the neighborhood-level and 29/57 were statistically significant (p≤0.05). Similar negative correlations were observed in analyses restricted to low SES groups. Finally, the negative correlations across countries, and within-countries, appeared to be stable over time in a sub-set of 36 countries.

Conclusion

The explicitly negative correlations between prevalence of underweight and overweight at the country-level and at neighborhood-level suggest that the hypothesized coexistence of underweight and overweight has not yet occurred in a substantial manner in a majority of LMICs.  相似文献

During the past decade the relationship between biodiversity and human diversity has received increased attention, resulting in the identification of what the Declaration of Belém calls an ‘inextricable link’ between biological and cultural diversity. Although the term biocultural diversity, introduced to denote this link, is being used increasingly, there has been little critical reflection on what it precisely refers to. I argue that it is used with particular reference to ‘indigenous traditional’ people, but that there is scope for extending its application within biocultural discourse. I therefore review the concept of culture and discuss what constitutes cultural values of the natural environment. I conclude that the concept of culture must be understood as involving a dynamic process of transcultural exchange and constant re-articulations of tradition resulting in the persistence of certain cultural practices. This approach ultimately reveals that the concept of biocultural diversity is also applicable to non-indigenous traditional communities.  相似文献

Background

Economic growth is widely perceived as a major policy instrument in reducing childhood undernutrition in India. We assessed the association between changes in state per capita income and the risk of undernutrition among children in India.

Methods and Findings

Data for this analysis came from three cross-sectional waves of the National Family Health Survey (NFHS) conducted in 1992–93, 1998–99, and 2005–06 in India. The sample sizes in the three waves were 33,816, 30,383, and 28,876 children, respectively. After excluding observations missing on the child anthropometric measures and the independent variables included in the study, the analytic sample size was 28,066, 26,121, and 23,139, respectively, with a pooled sample size of 77,326 children. The proportion of missing data was 12%–20%. The outcomes were underweight, stunting, and wasting, defined as more than two standard deviations below the World Health Organization–determined median scores by age and gender. We also examined severe underweight, severe stunting, and severe wasting. The main exposure of interest was per capita income at the state level at each survey period measured as per capita net state domestic product measured in 2008 prices. We estimated fixed and random effects logistic models that accounted for the clustering of the data. In models that did not account for survey-period effects, there appeared to be an inverse association between state economic growth and risk of undernutrition among children. However, in models accounting for data structure related to repeated cross-sectional design through survey period effects, state economic growth was not associated with the risk of underweight (OR 1.01, 95% CI 0.98, 1.04), stunting (OR 1.02, 95% CI 0.99, 1.05), and wasting (OR 0.99, 95% CI 0.96, 1.02). Adjustment for demographic and socioeconomic covariates did not alter these estimates. Similar patterns were observed for severe undernutrition outcomes.

Conclusions

We failed to find consistent evidence that economic growth leads to reduction in childhood undernutrition in India. Direct investments in appropriate health interventions may be necessary to reduce childhood undernutrition in India. Please see later in the article for the Editors'' Summary  相似文献

ABSTRACT

Museums around the globe have experienced important changes in recent years in response to decolonisation processes and the demands of indigenous peoples. French museums are no exception, but the transformations have certain French hallmarks. This article explores the way France is dealing with its colonial legacy and, by means of two case studies, unravels the diverse political and historical particularities of the French context. The first looks at the results of a comparative analysis of the French and Québécois public’s response to the travelling exhibition E tū ake: Standing Strong produced by the Museum of New Zealand Te Papa Tongarewa. The second focuses on the repatriation ceremony of Māori toi moko (tattooed preserved heads) that took place in Paris in January 2012. These two case studies examine the French uses of concepts such as ‘community’, ‘minority’, and ‘indigeneity’ as well as the complex relations between religion and rationality, ancestral presence and materialism in French public life. The article investigates how these concepts participate in the fabric of French society, and thus in shaping contemporary museum landscapes.  相似文献

Background

This study aimed to generate prioritised goals for oral health services for people with disabilities as a first step in meeting the need for evidence based oral health services for people with disabilities in Ireland.

Methods

The study used a three round modified e-Delphi method, involving dental service professionals and people with disabilities or their representatives, in Ireland. Three rounds were completed online using SurveyMonkey. Round 1 asked: “List what you think dental services for people with disabilities in Ireland should be like.” Items for subsequent rounds were generated from responses to Round 1. Round 2 and Round 3 used 5 point Likert scales to rank these items by priority: from No Priority (1) to Top Priority (5). Consensus was achieved on each item where at least 80% of respondents considered an item either High or Top Priority. A consensus meeting concluded the process.

Results

Sixty-one panelists started and 48 completed the survey. The Delphi panel agreed on level of priority for 69 items and generated 16 consensus statements. These statements covered a range of topics such as access to care, availability of information and training, quality of care, dental treatment and cost. A recurrent theme relating to the appropriateness of care to individual need arose across topics suggesting a need to match service delivery according to the individual''s needs, wants and expectations rather than the disability type/diagnosis based service which predominates today.

Conclusions

This process produced a list of prioritised goals for dental services for people with disabilities. This creates a foundation for building evidence-based service models for people with disabilities in Ireland.  相似文献

Feeding and oviposition preference studies of Helopeltis theivora Waterhouse, on leaves and stems of tea, Camellia sinensis L.(O)Kuntze, revealed that the insect mostly preferred the second leaf for feeding in comparison to the first, and the third leaf and stems; while the fifth instar nymphs were the most voracious feeders among the life stages, producing themost and largest feeding lesions. The insect preferred to oviposit mainly on stems and very few eggs are found on leaves.  相似文献

Dental modifications in the Caribbean are considered to be an African practice introduced to the Caribbean archipelago by the influx of enslaved Africans during colonial times. Skeletal remains which exhibited dental modifications are by default considered to be Africans, African descendants, or post-contact indigenous people influenced by an African practice. Individual E-105 from the site of Canímar Abajo (Cuba), with a direct 14C AMS date of 990–800 cal BC, provides the first unequivocal evidence of dental modifications in the Antilles prior to contact with Europeans in AD 1492. Central incisors showing evidence of significant crown reduction (loss of crown volume regardless of its etiology) were examined macroscopically and with a scanning electron microscope (SEM) to determine if the observed alterations were due to deliberate modification or other (unintentional) factors considered: postmortem breakage, violent accidental breakage, non-dietary use of teeth, and wear caused by habitual or repeated actions. The pattern of crown reduction is consistent with deliberate dental modification of the type commonly encountered among African and African descendent communities in post-contact Caribbean archaeological assemblages. Six additional individuals show similar pattern of crown reduction of maxillary incisors with no analogous wear in corresponding mandibular dentition.  相似文献

A universal Tree of Life (TOL) has long been a goal of molecular phylogeneticists, but reticulation at the level of genes and possibly at the levels of cells and species renders any simple interpretation of such a TOL, especially as applied to prokaryotes, problematic.One of the several ways in which microbiology puts the neo-Darwinian synthesis in jeopardy is by the threatening to “uproot the Tree of Life (TOL)” [1]. Lateral gene transfer (LGT) is much more frequent than most biologists would have imagined up until about 20 years ago, so phylogenetic trees based on sequences of different prokaryotic genes are often different. How to tease out from such conflicting data something that might correspond to a single, universal Tree of Life becomes problematic. Moreover, since many important evolutionary transitions involve lineage fusions at one level or another, the aptness of a tree (a pattern of successive bifurcations) as a summary of life’s history is uncertain [24].  相似文献
