Post-1965 demographic changes in the United States [US] have brought blacks, Latinos, and Asian Americans into direct conflict, raising the question of how and whether law and public policy should attempt to adjudicate conflicts among racialized minority groups. I argue in this article that for the past few decades, national political leaders in the US have promoted an official multiculturalist discourse that actually discourages Americans from naming and addressing these intergroup tensions. This discourse superficially reimagines race and nation – by moving from a biracial, black-white focus to a formal acknowledgment of multiracial difference – while refusing to acknowledge the complex interminority inequalities and antagonisms generated by this new diversity. How might we refocus national attention on the serious interminority conflicts and racial justice struggles unfolding around us? I consider resurrecting the traditional notion of racial hierarchy as a counter-narrative to official multiculturalist discourse before arguing instead for one which involves a more complex notion of “racial positionality”.  相似文献

This paper draws from ethnographic research on entertainment television in the Philippines, in which poverty, suffering, abundance and joy are materialised and enacted as central themes. Examples are considered from a particularly successful Philippine television program, Eat Bulaga, in which audience members compete to win prizes of cash, bank accounts, feasts, appliances or vehicles. While the production of this television program creates a wider, mediated representation of poverty and abundance, suffering and joy, the paper focuses on the practices and experiences of the people – including production staff and audience members ‐ whose participation in the making of this television program is a materially, and at times spiritually, transformative event. In doing so, Eat Bulaga consolidates and remediates a large market of television audiences whose self‐understanding incorporates the mass consumption of particular goods as being central to the Philippine experience of poverty‐in‐modernity.  相似文献

Storage fungi and seed health of rice: A study in the Philippines   总被引:1,自引:0,他引:1  
Fifty seed samples of different rice varieties stored in warehouses for varying periods (1–28 months) were collected and screened for their fungal flora, using standard blotter and agar plate methods, resulting in the isolation of 36 fungal forms. The samples were also studied for moisture content, germinability, and seedling abnormalities. Significant correlations were found among the numbers of fungi, storage period, and germinability. Fourteen samples, seven each of IR64 and IR66 were studied with regard to moisture content, germination test, abnormal seedlings, speed of germination, conductance of leachates, total dehydrogenase activity, total free amino acids, total soluble sugar, fat acidity, gelatinization temperature, gel consistency, amylose content, translucency, and per cent whiteness. Significant relationships were found between the fungi and the parameters studied.  相似文献

The self/non-self model, first proposed by F.M. Burnet, has dominated immunology for 60 years now. According to this model, any foreign element will trigger an immune reaction in an organism, whereas endogenous elements will not, in normal circumstances, induce an immune reaction. In this paper we show that the self/non-self model is no longer an appropriate explanation of experimental data in immunology, and that this inadequacy may be rooted in an excessively strong metaphysical conception of biological identity. We suggest that another hypothesis, one based on the notion of continuity, gives a better account of immune phenomena. Finally, we underscore the mapping between this metaphysical deflation from self to continuity in immunology and the philosophical debate between substantialism and empiricism about identity.  相似文献

In the Chinese cultural tradition, numbers may be seen as meaningful, creative, even poetic things, and they figure prominently in accounts of the self. Rather than ‘reducing people to numbers’, quantification is used – by at least some people some of the time – as a mode of differentiating themselves from others, a means of narrating unique life experiences. This paper explores the role of numbers in accounts of the self, drawing primarily on a case study of one woman from rural Taiwan. It is suggested that a natural historical framework can help illuminate numbers and number systems as Chinese technologies of the imagination.  相似文献

Important events relating to the sovereignty dispute over the Spratly Islands have arisen by fits and starts since 2009, marking the start of a new phase in the legal battle over territorial and maritime claims in the South China Sea. While the exchange of legal arguments between the parties has gradually laid bare their maritime claims, much still remains shrouded in uncertainty. Among the obscure claims wanting clarification is China's infamous nine-dotted-line map, which in 2011 elicited a response and counterresponse between the Philippines and China. This article examines the maritime and territorial claims of the Philippines and China as revealed in the recent discord over the nine-dotted-line map.  相似文献

BACKGROUND: Findings from animal experiments suggest a link between poor maternal zinc status and increased risk of oral clefts in offspring; however, there are few human studies on this issue. METHODS: A case-control study was conducted using 74 case mothers of children with nonsyndromic cleft lip with or without cleft palate (CL/P, n=57) or cleft palate alone (CP, n=17), and 283 control mothers of unaffected children recruited in the Philippines in early 2003. Maternal zinc status was assessed by determining plasma zinc concentrations a mean of 5 years after delivery of the index child. Odds ratios (ORs) of estimates of the relative risk of oral clefts were calculated for quartiles of maternal plasma zinc concentrations. RESULTS: The mean plasma zinc concentration of CL/P case mothers (9.6+/-1.2, SD micromol/l) was significantly lower than that in control mothers (10.1+/-1.6 micromol/l; P<0.05). Low plasma zinc concentrations (<11.0 micromol/l) were found in 88% and 94% of CL/P and CP case mothers, respectively, and in 72% of controls (P<0.05). The ORs for CL/P and CP combined, adjusted for potential confounding factors, decreased with increasing quartile of plasma zinc as follows: 1.0 (lowest quartile reference), 0.83 (95% confidence interval 0.37-1.89), 0.70 (0.31-1.68), and 0.26 (0.10-0.70) (P trend=0.008). CONCLUSIONS: Low plasma zinc concentrations were common in Filipino women of reproductive age, and higher plasma zinc concentrations were associated with a lower risk for oral clefts in their children.  相似文献

The last 7000 years of environmental history for Paoay Lake and its surrounding landscape is examined through the analysis of pollen, diatoms, charcoal, mineral magnetics and AMS dating. Basal sediments contain shells of Cerithiidae and the saline‐tolerant diatom Diploneis indicating that this was an estuarine environment before becoming a freshwater lake after 6000 bp . Pollen analysis shows that submontane forests, characterized by Pinus pollen, underwent a major disturbance around 5000 years ago, recovering to previous levels by 1000 years ago. Charcoal as an indicator of fire is abundant throughout record, although the highest levels occur in the earlier part of the record, between 6500 and 5000 years ago. An aspect of the project was to examine whether there is evidence of land clearance and agricultural development in the region during the late Holocene. While a clear signal of human impact in the record remains equivocal, there appears to be a correspondence between submontane forest decline and mid‐Holocene ocean data that depict warmer and possibly drier conditions for the region. The study highlights the vulnerability of these montane forests to forecasts of a warmer and drier climate in the near future.  相似文献

Basidiomata of putative ectomycorrhizal fungi have been collected from under pine or dipterocarp stands in Central Luzon in the Philippines. Over 100 collections are reported. Among the material, 75 taxa have been recognised and assigned to known genera or at least placed close to already documented European, Japanese or North American taxa. Formal identifications for 46 species are given along with comments on previous collections from South-East Asia. Species collected from under the native Pinus kesiya resemble the communities found under three-needled pines in North America and the West Himalayas, whereas those from dipterocarp forests were similar to communities found in Malaysia and Japan. Members of the Sclerodermatales were particularly common and are probably the pioneer colonizers of young seedlings in these ecosystems.  相似文献

Local fisherfolk and fishpond owners have been practicing “restoration” of mangrove forests in some parts of the Philippines for decades, well before governments and non‐government organizations began to promote the activity as a conservation tool. This paper examines ecological characteristics of these mangrove plantations and compares them to natural mangroves in the same areas. Mangrove planters were interviewed and plantation and natural mangrove forests were surveyed to measure forest structure, composition and regeneration. Compared with natural forests, mangrove plantations were characterized by high densities of small stems, shorter and narrower canopies, and fewer species. For both economic and ecological reasons, the vast majority of people dispersed and planted only Rhizophora mucronata/stylosa and, furthermore, they often thinned other species out of planted areas. There was remarkably little subsequent recruitment of other, nonplanted mangrove species into plantations up to 50 and 60 years of age. This pattern held across a diversity of sites, including plantations that had not been selectively cut or weeded. Important ecological and economic benefits result from local mangrove planting, but catalyzing diverse forest regeneration—at least in the short to medium term—is not one of them. The lesson: if you want to restore diverse mangrove forests, you have to plant diverse mangrove forests.  相似文献

The worldwide degradation of reef ecosystems has promoted the advocators of restoration acts to the foreground. Here, we describe the results of the first step of large-scale restoration based on the “gardening with corals” concept. During June-September 2005, two coral nurseries were established in Bolinao, the Philippines, in front of Silaqui Island, in a shallow (2 m depth) sandy lagoon. Two types of nurseries were employed: (1) suspended nursery; (2) leg-fixed nursery. The nursery held a total number of 6824 ramets, from seven coral species representing different growth forms (branching, leaf-like and sub-massive forms) and different growth rates (fast and slow growing species). Each species was represented by several genotypes. During one year, we analyzed and compared survivorship, bleaching and growth rates of fragments between the different nurseries, species and genotypes. Survivorship, which was high in both nurseries, > 85%, fluctuated between the different species indicating that different species require different rearing methodologies. Mortality and detachment was subjected to environmental conditions, especially affected by the typhoons prevailing in this part of the world. The one-year nursery phase produced sizeable colonies, especially of branching forms, suitable for transplantation.  相似文献

Summary The self-sterility ofHalocynthia roretzi from Mutsu Bay, Japan, was examined. This sterility is strict and not a single egg can be fertilized in self-sterile animals. Less than 2% of the animals were self-fertile (with 100% cross-fertility). All heterologous sperm can fertilize all eggs, although there are pairs of individuals in which the coelomocytes recognize each other as self. Eggs deprived of follicle cells cannot be fertilized by either autologous or heterologous spermatozoa. Detached autologous or heterologous follicle cells can reattach to the chorion in calcium-enriched sea water and the reconstituted eggs recover their ability to be fertilized. A mosaic egg can therefore be obtained, which consists of oocyte, test cells and chorion originating from one individual and follicle cells from another. The mosaic egg was used to determine the site of recognition of self and non-self. The results indicate that the recognition resides in the chorion and/or test cells, probably the chorion. The relationship between somatic alloreactivity, previously found in coelomocytes ofH. roretzi, and gamete reactivity is discussed.  相似文献

This article explains the position(s) of the United States in the maritime dispute adjacent to Svalbard. While the United States has regarded Norway's exclusive claim to the natural resources outside Svalbard as everything from “wishful thinking” to legally plausible, Washington maintains that it may have rights under the 1920 Svalbard Treaty to exploit the maritime zones adjacent to the archipelago. The U.S. reservation is the result of assessments and reassessments of legal considerations as well as national interests.  相似文献

Each year, there are approximately 1.24 million deaths due to road traffic injuries, the majority of which occur in low- and middle-income countries. Since 2008, 35 countries have passed legislation to implement road safety strategies. However, many countries have yet to pass comprehensive legislation while others lack adequate enforcement of current policies. The annual global mortality rate due to road trauma remains unacceptably high and reflects the need for governments to prioritize the passage and implementation of road safety legislation.Alcohol is a leading risk factor for road trauma globally and the leading cause of death and disability in the Western Pacific region. Despite the overwhelming evidence that strict enforcement of drunk-driving policies can lead to a drastic reduction in alcohol-related road incidents, many countries in the Western Pacific lack sufficient data that could facilitate the design of appropriate drunk-driving interventions.This paper provides an analysis of the current status of policies and attitudes related to alcohol and road injuries throughout the Western Pacific region, with a specific focus on the Philippines. Following the passage of drunk-driving legislation in 2013, a medical records review of alcohol-related road trauma patients in Manila Doctors Hospital was conducted. The findings of this pilot project further highlight the pervasive problem of missing or unreliable data regarding alcohol’s role in road trauma. Assessing the burden of drunk driving is an important step in designing effective interventions and systematically changing attitudes about driving under the influence.  相似文献

Based on 16 months of field observations on tagged seahorses Hippocampus comes in the Philippines, adults were found to be nocturnal, to maintain small home ranges, and to live mostly among corals. Prolonged pair associations suggested that H. comes , like many other seahorse species, were probably monogamous, a conclusion consistent with their low density and sparse distribution. Site and mate fidelity suggest that H. comes populations may fare poorly under current high levels of exploitation.  相似文献

Temporal variation in macroinfaunal community structure wasassessed from monthly monitoring of the sandy substrate of theLucero reef flat in Bolinao, Pangasinan (northwesternPhilippines)between November 1990 and November 1991. The community wascomposedof 98 taxa from 10 phyla and was consistently dominated by thepolychaete family Syllidae (19–33% of monthly totalabundance).Five polychaete and crustacean taxa co-dominated with thesyllidsand exhibited monthly shifts in dominance ranks. Overall,there wasno significant change in the composition of the communityafter ayear.Results of the study show that the temporal dynamics of thecommunity was a function of the seasonality in salinity and oftherelatively consistent nature of the substrate. Abundances ofmacroinfaunal crustaceans, chaetognaths, and molluscsfluctuatedsignificantly over 12 months, and corresponded to the seasonalfluctuation in salinity. Total and polychaete abundances didnotshow significant monthly variation, but tended to beinfluenced bysalinity changes. Densities of turbellarians, nemerteans, andechinoderms appeared homogeneous across 12 months, andcorrelatedwith the consistency of substrate structure in the reef flatoverthe experimental period. In addition, sipunculid numbersseemed tobe supported by the stable amount of organic matter in thesandysubstrate.  相似文献

A new genus and new species of terrestrial potamid crab ( Carpomon pomulum) is described from the island of Palawan in the Philippines. This new genus can easily be distinguished from all other Philippine potamids in its smooth and inflated carapace, no trace of an epibranchial tooth, extremely low postorbital cristae, and stout and twisted male first gonopod. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

A 56-year time series of human plague cases (Yersinia pestis) in the western United States was used to explore the effects of climatic patterns on plague levels. We found that the Pacific Decadal Oscillation (PDO), together with previous plague levels and above-normal temperatures, explained much of the plague variability. We propose that the PDO's impact on plague is conveyed via its effect on precipitation and temperature and the effect of precipitation and temperature on plague hosts and vectors: warmer and wetter climate leading to increased plague activity and thus an increased number of human cases. Our analysis furthermore provides insights into the consistency of plague mechanisms at larger scales.  相似文献
