Chronic undernutrition and hunger remain significant problems for children, in global perspective, and may have important implications for children's ability to function effectively at school. In this paper, we capitalize on a longitudinal data set of children in 100 villages in Gansu Province to estimate differences in achievement, behavior, and long-term persistence associated with chronic undernourishment and short term hunger. We show that chronic undernourishment and short-term hunger relate to children's school functioning in distinct ways: chronically undernourished children have poorer literacy acquisition and subsequent school persistence, while children who report subjective hunger have more behavioral problems. 相似文献

Abstract Ghrelin is a hormone that stimulates hunger. Intense exercise has been shown to temporarily suppress hunger after exercise. In the present study, we investigated whether post-exercise hunger suppression is mediated by reduced plasma total ghrelin concentrations. Nine men and nine women participated in the study. Their mean physical characteristics were as follows: age 24.8 (s x = 0.9) years, body mass index 22.9 (s x = 0.6) kg · m?2, maximal oxygen uptake ([Vdot]O2max) 57.7 (s x = 2.2) ml · kg?1 · min?1. The participants completed two 3-h trials (exercise and control) on separate days in a randomized balanced design after overnight fasts. The exercise trial involved a 1-h treadmill run at 73.5% of [Vdot]O2max followed by 2 h of rest. The control trial consisted of 3 h of rest. Blood samples were collected at 0, 0.5, 1, 1.5, 2, and 3 h. Total ghrelin concentrations were determined from plasma. Hunger was assessed following blood sampling using a 15-point scale. The data were analysed using repeated-measures analysis of variance. Hunger scores were lower in the exercise trial than in the control trial (trial, P = 0.009; time, P < 0.001; trial × time, P < 0.001). Plasma total ghrelin concentrations did not differ between trials. These findings indicate that treadmill running suppresses hunger but this effect is not mediated by changes in plasma total ghrelin concentration. 相似文献

裕固族当代作家达隆东智的中篇小说《雪落地的声音》以"讲鬼故事"的态度反思历史,通过一系列荒诞神秘、阴森诡异的事件展现主人公萨拉尔由"饿"至"疯"的心理变化过程,并在悬疑恐怖中表达作者对一个时代的理性审视。"饿"是小说的中心词之一,人物的恐惧与不幸命运,都与饥饿这一生理需要的无法满足密切相关。究其实质,"饿"即个体特定年代求生不易、求死不甘,生也恐惧、死也恐惧的矛盾心理的写照。这一二难命题的难以抉择性,最终导致了萨拉尔的疯狂。与此同时,对这一命题的哲学探讨,却赋予了文本深邃的内涵和丰富的张力,使其在或单纯再现特定历史阶段的现实主义小说,或以恐怖、悬疑取胜的恐怖小说,或形而上思考多于文学表现的哲理小说中脱颖而出,并与其独特的地域、民族文化表现一起,标志着作者题材选择的突围和文学表现的日益成熟,拥有多重阐释的空间。 相似文献

What are the experiences of health at the margins of the globe? How do the material inequities in the distributions of resources across the globe play out in the expressions of the experiences of health in the localized contexts of the global margins? In this synthesis essay, I draw upon three interconnected ethnographies conducted over several villages in West Bengal, India, over a decade-long period to explore the alternative rationalities of health that emerge at the margins. At the heart of these ethnographies is the commitment to culturally center narratives of health as hunger, foregrounding the everyday experiences of hunger and the expressions of agency at the margins in securing access to food resources. Based on the synthesis of the ethnographies, entry points are suggested for the praxis of social change communication that builds on the articulation of health as hunger and imagines localized strategies of collective resistance. 相似文献

多丽斯·莱辛的《饥饿》收录在她的《五部短篇小说》中,发表于1953年,是她后殖民主义小说中很具代表性的一部。此论文分成三个部分。第一部分解释了为什么《饥饿》是一部后殖民主义短篇小说;第二部分通过介绍后殖民主义的总的观点并具体介绍萨义德和巴巴的后殖民理论提出了此论文研究的理论基本原理;第三部分运用了后殖民理论分析文本,主要关注了莱辛的叙事策略和牙巴乌的身份探寻。 相似文献
