How do elites perceive poverty and the poor? In this article, we present the results of interviews with eighty members of the Filipino elite, undertaken as part of a larger six‐country study of elite perceptions of poverty and the poor. Poverty, we argue, is a highly subjective phenomenon. People's perceptions of poverty, of who is and who is not poor, of how poverty affects them and others, and of how poverty can be effectively tackled, vary enormously between different types of people (defined in terms of class, status, occupation, nationality, ethnicity, gender or a myriad of other social identities). Wherever people cohere as groups, classes or other social constructs, perceptions of poverty are aggregated and refined and then embedded in social dynamics. The study of elite perceptions of poverty and the poor, we conclude, can both add to our understanding of the social dynamics of poverty and inequality and inform pro‐poor public policy.  相似文献

While food allergy prevalence has been studied at the national level, we know little of food allergy prevalence or perceptions of prevalence/management at the local level. This paper uses Waterloo Region as a case study to 1) document self-reported individual and household food allergy and sensitivity prevalence at the local level; 2) investigate perceptions of food allergy prevalence; and 3) explore perceived confidence in anaphylaxis management. Survey data were collected from January to March 2019. Respondents (n = 500) self-reported individual and household food allergy and sensitivity, estimated the percentage of Canadians with food allergy, and were queried about their knowledge of food allergy management. Prevalence estimates were weighted to the structure of the 2016 Canadian Census, and univariate and bivariate analysis were conducted. Prevalence of self-reported food allergy was 12.1% (95%CI, 8.8%-15.3%), and prevalence of self-reported food sensitivity was 26.3% (95%CI, 21.9%-30.7%). When asked to estimate the percentage of Canadians with food allergy, the mean perceived percentage was 35.1% (SD = 22.96). Self-reported prevalence of food allergy appears higher in Waterloo Region, and the estimated percentage of Canadians with food allergy is inflated. Understanding prevalence and perceptions at the local level is important for targeted allocation of public health resources to ensure safe spaces for individuals with food allergy.  相似文献

Stimulated by several important, recent empirical advances, California archaeologists are engaged in a series of lively debates. These advances include new discoveries about the early peopling of western North America and sustained occupation of the California coasts as early as 12–13,000 BP. There also have been significant new developments in the role of paleoenvironmental change in cultural evolution, the emergence of long-distance interaction spheres, the presence of intensive craft specializations, and the appearance of sociopolitically complex hunter–gatherers. This article addresses these issues—and several others—with a view to the general interests of scholars worldwide. The exceptional heterogeneity of California ecosystems (from deserts to dense redwood forests to bountiful offshore islands) and the remarkable cultural diversity exhibited by the dozens of major groups who made these lands their home combine to produce a complex indigenous sociopolitical picture. Current understandings reveal myriad trajectories of cultural change across nine major subregions of the state.  相似文献

This article reviews the state of the two security and defence institutions available to west Europeans: NATO and the EU's common European Security and Defence Policy (ESDP). In each case, the authors assess the political maturity and stability of the institution, and then ask what it can contribute in terms of coordinated military capability to west European's strategic readiness. NATO's Prague summit in November 2002 will address the thorny issue of the next tranche of post–Cold War enlargement. But beyond the predictable debate about which candidates to admit, and what should be offered to those unsuccessful in their bid, there will be a far more urgent and important agenda to be discussed at Prague—the military capabilities of the European allies. Given that ESDP is still far from achieving its capability goals, the authors argue that the time is right for European allies to begin thinking in terms of generating a composite, joint strike force which could be configured to be interoperable with US forces and which could salvage something useful from the disheartening lack of progress in developing a European military capability.  相似文献

Florisbad, an open-air spring site with 7 m of strata, has yielded the type assemblage of Middle Stone Age (MSA) fauna, the cranium of an archaic hominid in 1932 and an extensive sequence of MSA artefacts in the 1980s. The cultural assemblages include an early MSA dated broadly to 279,000±47,000 years, a highly retouched form of MSA at 157,000±21,000 years and a minimally retouched, expedient MSA assemblage from a series of occupation horizons at 121,000±6000 years. The latter represents multiple brief visits to a hunting and butchery site on the edge of an active spring pool, where periodic sedimentation gently buried occupation debris in a near-pristine context. Periods of lower spring discharge are represented by organic horizons as swampy vegetation encroached on the springs, while periods of higher spring discharge created pools. Overall the spring sequence indicates low-energy subaqueous environments similar to lakes, ponds or backwater sites. The sequence is characterized by fine sands, silts and clays responsible for the good archaeological preservation.  相似文献

Unusually large fontanelles were found in four skeletons of children from a cemetery in the North West Province of South Africa. These remains date from the last decade of the 19th and first half of the 20th century. Three small infants (two of about nine months, and one of about six months) and one child (of about three years) were affected. In the case of the three‐year‐old child pathologic changes were evident on the rest of the skeleton, which probably resulted in the delayed closure. The cause of the unusually large fontanelles in the other three individuals is less clear. Some possibilities are discussed, but it seems as though general hardship and malnutrition, congenital syphilis or other infectious diseases like rubella syndrome may be involved.
