Many Congolese seem to have withstood their country’s protracted economic crisis relatively well, despite its length and severity. This study analyses whether and to what extent this livelihood paradox can be explained by a strategy of asset depletion. In general, this strategy seems not to have played an important role. Marked reductions in household asset stock were limited to some secondary urban centres. Explanations for this strategy’s limited reach point to a much richer set of asset coping mechanisms which households may have developed regarding assets in times of hardship, and to a concomitant shortage of research strategies to take due account of these.  相似文献

A theory of public action will be a sociological one, for it can explain the activities of different individual stakeholders who are both driven by varied motives and interests and are required to come together for achieving some avowedly public objective. On the basis of a review of scholarly literature and three case studies of public action (based on ethnographic fieldwork) in an Indian village, this study observes that public action is far more complex than celebrated problems of collective action. In public action we want collective action to happen and deliver optimum outputs for target publics. But this should at the same time offer gains, rewards, and outcomes of different kinds to different stakeholders. This discussion aims to outline the scope and possible types of public action. Such a discussion has important implications, for policy as public action should be designed adequately as collective action with differential rewards in place for participants.  相似文献

Calliphoridae are one of the most important insect groups encountered as evidence collected from a crime scene. Age determination of the immature stages of these necrophagous flies is an important step toward estimating the time of colonization and inferring a minimum postmortem interval (PMImin) in most instances. To determine if the cuticular hydrocarbons could be used to establish whether the development stages yield characteristics profiles, allowing for age estimation, hydrocarbons were extracted from 1st and 2nd, as well as feeding and post‐feeding 3rd instar Chrysomya rufifacies, the hairy maggot blow fly. Extracted hydrocarbons were analyzed using gas chromatography coupled to mass spectrometry with the aim to investigate the changes in chemical profiles of each larval stage. A total of 23 compounds were identified with most of them being alkanes (65%) with carbon chain lengths of 9–33 carbons, alkenes (18%), and methyl‐branched alkanes (17%). All the hydrocarbons except pentadecane (C15), hexadecane (C16), and nonacosane (C29) showed significant differences in their expression throughout larval development. For 1st instars, nonane was the most abundant (17% of the total hydrocarbons content) compound. Accounting for 11% and 10% of the cuticular hydrocarbons, tricosane and pentacosane, respectively, were the notable hydrocarbons in 2nd instars. For post‐feeding 3rd instars, hentriacontane and tritriacontane were present with relative abundances 18% and 15%, respectively. On average, there was a shift from low to high molecular weight hydrocarbons as the larvae aged. These results indicate the change in hydrocarbons makeup as larvae age and could potentially be used to determine the age of immature C. rufifacies and hence aid in PMImin estimations. However, future research is needed to validate these results under natural conditions in the field.  相似文献

Abstract

Color removal from wastewater has been a matter of concern, both in the esthetic sense and health point of view. Color removal from textile effluents on a continuous industrial scale has been given much attention in the last few years, not only because of its potential toxicity, but also due to its visibility problem. The ability of wheat husk to act as biosorption medium in the removal of dyes from aqueous solution was successfylly investigated. The analysis of dye remaining in the solution was done colourimetrically using a spectrophotometer. It may be concluded that easy availability and suitability for production of bioadsorbent from wheat husk makes it one of the materials that can be used for removal of RB 19 and RB 195 from waste water.  相似文献

Abstract: Ricin is a glycoprotein from Ricinus communis seeds. It is known to have diverse toxic effects on cells of different visceral organs. In the present study, we purified and denatured ricin in a boiling water bath for different time intervals. We further made an attempt to identify native and denatured ricin by immunobased detection systems. All the antigen/antibody‐based assays identified native and denatured ricin. On SDS–PAGE, only native ricin was observed. In western blotting, ricin boiled for 3.75 min gave a strong band on X‐ray film. On native polyacryl amide gel electrophoresis, native and denatured ricin gave ricin band in 60‐kDa region. The denatured ricin did cause mortality up to 25 mg/kg, while 5 and 10 μg/kg of native ricin caused 50% and 100% mortality, respectively. Detection of native and denatured ricin is very difficult, and the investigating agencies, forensic scientists, and analysts should be very careful while interpreting the results.  相似文献

Folic acid is B‐9 vitamin. Folic acid is prescribed commonly for pregnant women to prevent neural tube defects in the fetus, patients under chemotherapy, pernicious anemia and to reduce the risk of stroke and cardiovascular disease. Acute or chronic ingestion of a large dose of folic acid generally manifests as neurological complications, which are reversible. In this present case, a 23‐year‐old pregnant woman committed suicide by consuming folic acid tablets and succumbed to death within 36 h. Postmortem toxicological analysis detected folic acid in viscera. Death following acute consumption of folic acid is rare and has been not reported in the literature, to the best of our knowledge.  相似文献

Violence against women, especially spousal violence is a common phenomenon in India which is significantly increasing over the years. In the name of socialization, male dominated orthodox Indian society raises girls to endure male aggression without protest. Indian social norms within this conservative environment discourage women’s employment; consequently, employed women are subjected to more abuse compared to their unemployed counterparts. The current study, based on the National Family Health Survey data, documents the nature and extent of spousal violence against married employed women across job categories. The study reveals that the majority of employed women are skilled or unskilled manual workers, and most of them are subjected to spousal violence. Furthermore, higher category jobs do not protect women from spousal violence. Women’s empowerment, higher education and/or occupation compared to their partner, and partner’s alcoholism further induce cruelty on employed women. However, standard of living and a husband having a comparatively better job are found to reduce spousal violence.  相似文献

A growing number of U.S. cities have large numbers of untested sexual assault kits (SAKs) in police property facilities. Testing older kits and maintaining current case work will be challenging for forensic laboratories, creating a need for more efficient testing methods. Methods: We evaluated selective degradation methods for DNA extraction using actual case work from a sample of previously unsubmitted SAKs in Detroit, Michigan. We randomly assigned 350 kits to either standard or selective degradation testing methods and then compared DNA testing rates and CODIS entry rates between the two groups. Results and conclusions: Continuation‐ratio modeling showed no significant differences, indicating that the selective degradation method had no decrement in performance relative to customary methods. Follow‐up equivalence tests indicated that CODIS entry rates for the two methods could differ by more than ±5%. Selective degradation methods required less personnel time for testing and scientific review than standard testing.  相似文献

The implementation and effective management of watershed-development projects is recognised as a strategy for rural development throughout the developing world. Several government and non-government agencies have launched watershed-development projects to tackle the challenges of soil conservation, improving land productivity, and economic upliftment of the rural poor for efficient use of natural resources. Participatory community-driven institutions of integrated watershed management are considered vital for the sustainability of natural resources. This study focuses on the impact of local institutions on watershed development in India and examines the degree of women's participation in relation to the effective management of natural resources and sustainable development.  相似文献
