Epidemiology of tornado destruction in rural northern Bangladesh: risk factors for death and injury

The epidemiology of tornado-related disasters in the developing world is poorly understood. An August 2005 post-tornado cohort study in rural Bangladesh identified elevated levels of death and injury among the elderly (≥ 60 years of age) (adjusted odds ratio (AOR) = 8.9 (95 per cent confidence interval (CI): 3.9-20.2) and AOR = 1.6 (95 per cent CI: 1.4-1.8), respectively), as compared to 15-24 year-olds, and among those outdoors versus indoors during the tornado (AOR = 10.4 (95 per cent CI: 5.5-19.9) and AOR = 6.6 (95 per cent CI: 5.8-7.5), respectively). Females were 1.24 times (95 per cent CI: 1.15-1.33) more likely to be injured than males. Elevated risk of injury was significantly associated with structural damage to the house and tin construction materials. Seeking treatment was protective against death among the injured, odds ratio = 0.08 (95 per cent CI: 0.03-0.21). Further research is needed to develop injury prevention strategies and to address disparities in risk between age groups and between men and women.     

农业化肥污染的政策成因及对策分析

化肥污染是农村面源污染的重要组成部分,如何解决该问题已经成为中国学者热议的话题。为了定量分析国家政策对化肥过量施用的影响,基于我国1998—2007年各省市的面板数据,借助STATA软件包和化肥施用效用模型假设,对其进行了回归分析。结果表明：一是随着经济发展水平的提升,农业化肥污染仍会不断加剧。二是多年来国家给予化肥企业＂优惠＋补贴＋限价＂的化肥行业发展政策是化肥过量施用的根本政策原因,当前国家惠农政策有助于降低化肥的需求量。三是当国家取消对化肥企业的补贴政策,继续当前的惠农政策时,则农民直补政策需以农民有利于环境的施肥方式为前提。四是若国家继续当前化肥行业发展政策和惠农政策,则视国家给予化肥企业的补贴确定一个直补额度,当对农民直补小于该额度时,则直补有利于农民减少对化肥的需求;但当直补超过这一额度时,农民则会增加对化肥的需求,因此后者需以农民施肥行为有利于环境为前提。     

Repetitive Strain in Nonrepetitive Work: A Case Study

In a Québec factory, a woman in a nontraditional job suffered from epicondylitis whereas her male coworkers were unaffected. A study was undertaken in order to enumerate the operations at risk for epicondylitis. Workers were interviewed in order to identify difficult operations and systematic observations were done over 4 work days. Although tasks were extremely varied, certain movements at risk for epicondylitis were repeated many times. Fifty-three valves were turned against resistance as part of this job, and one valve requiring a particularly difficult movement was turned 20 times in one day. There were at least 61 operations at risk for epicondylitis per day over a 4-day period. Strain on the elbow joint was particularly intense for the woman worker because the design of the workplace gave an advantage to taller workers with larger hands. Although this case study does not permit us to conclude that the worker’s epicondylitis was due to her job, it enables us to suggest that it would be wise to adapt the dimensions of relevant equipment and worksites to a wider range of potential worker sizes. We also raise some questions about the definition of repetitive strain in epidemiological studies. We suggest that it may be necessary to consider not only the cycle time but also the total of forces exerted on a joint in order to study workplace injuries to the musculoskeletal system.     

湿地退耕还湿与替代生计选择的农民响应研究——以三江自然保护区为例

通过对三江自然保护区核心区内6个村屯和实验区内5个村屯的310家农户家庭就退耕还湿和替代生计选择的问卷调查分析发现,在退耕还湿问题上,不同区域位置、年龄结构和耕地拥有量决定了他们对退耕还湿支持意愿的不同,表现在实验区内的农民和农民中的年轻人支持率要高,耕地在6~12hm²之间的农民支持率最低;农民反对退耕还湿的原因和农民接受退耕还湿的补偿选择都凝结着农民对现有耕地及补偿制度的思考。在替代生计选择上,当地居民没有明确的目标,多倾向于有保障的种植业调整。研究表明:农民对退耕还湿的支持主要取决于能否保证自身的经济利益,并且与农民的收入来源和谋生能力有关;替代生计发展的不健全和不稳定,使得农民仍把土地作为重要的生活保障。缺乏明确的退耕还湿补偿制度和替代生计引导是退耕还湿实施的制度障碍和政策缺失;基于当地农民考虑,提出了核心区生态移民、缓冲区传统农业改造和实验区多元化产业发展总体替代生计模式。     

基于多层次模型的农户土地利用决策影响因素分析——以陕西省米脂县高西沟村为例

土地利用变化驱动力研究一直是学者们关注的热点问题之一,土地利用驱动力在不同尺度的变化也越来越受学者们关注。论文以陕西省米脂县高西沟村为研究区域,在地形图、航片解译数据及2009年实际测量数据和农户调查数据的基础上,基于多层次模型的理论,借助HLM6.07(student)软件工具,构建从地块(微观尺度)到农户(中观尺度)的二层土地利用决策影响因素模型,试图揭示微观层面土地利用决策的影响因素在不同尺度上的变化机制。研究结果表明:①农户选择种植土豆、谷子作物的土地利用决策与地块的自然因素和农户的社会经济因素有关;②农户种植土豆、谷子行为决策的影响因素存在差异;③将多层次模型应用到从微观尺度到中观尺度分析农户土地利用决策影响因素是符合实际情况的,这为进一步构建影响农户土地利用决策的因素——微观尺度(地块)、中观尺度(农户)、宏观尺度(村庄)的三层模型奠定了基础,同时为研究土地利用决策机制提供了一种方法。     

基于农户视角的脱贫类型划分与路径研究——以新晃侗族自治县84个出列村为例

以新晃侗族自治县（以下称“新晃县”）84个出列村农户为研究对象,从基础设施、教育医疗、收入状况、产业发展四个方面构建脱贫成效指标体系,对2019年新晃县出列村农户脱贫成效的空间格局、脱贫类型划分与路径进行研究。结果表明：（1）新晃县出列村农户脱贫成效呈现出明显的空间分异特征,基础设施脱贫成效平均得分为2.53,整体呈“北高南低”的态势;教育医疗脱贫成效平均得分为2.65,呈现出“东南高、西北低”的空间分布格局;收入脱贫成效平均得分为2.48,呈高、中、低得分区域交替分布态势;产业脱贫成效平均得分为4.23,但差异明显,仅东部、南部少数村域得分较高。（2）新晃县出列村农户脱贫类型可分为单因素主导脱贫型、双因素驱动脱贫型、多因素综合脱贫型三个大类和F因素主导型、F-E因素驱动型、P-E-I因素综合型等13个小类,同时针对不同脱贫类型提出巩固脱贫成效的策略与路径。

Land-use choices: the case of conservation reserve program (CRP) re-enrollment in Kansas,USA

Among the important alternatives for land conservation is the US Conservation Reserve Program (CRP) that celebrated its 30th anniversary in 2015. This paper explores how landowners decide on alternative land-use choices made available by the expiration of CRP contracts in Kansas. The study uses survey data and multinomial Logit models to predict land-use choices. Two models were tested. The first model does not incorporate variables concerning farmer perceptions and attitudes about land-use choices, while the second model does. The results show that CRP re-enrollment depends on factors, such as years of experience in cropping and percent of cropland irrigated. However, when perception variables are added, the models become more robust in explaining other land choice alternatives. The results suggest that as the perception of unfairness of more inflexible environmental policy rises, these farmers may be more likely to re-enroll their marginal land in the CRP program.     

土地征用的农户收入效应——基于倾向得分匹配(PSM)的反事实估计

我国正处在经济社会发展转型期和城镇化高速推进期,土地征用和失地农户将是长期存在的社会现象,但土地征用是否会具有收入效应仍然莫衷一是,缺乏准确估计。本文基于2011年成都市"农村住户家庭问卷调查数据",利用倾向得分匹配(PSM)方法,估计了土地征用对失地农户收入的影响,为检视政府土地征用补偿制度合理性,健全政府土地征用政策、缓解土地征用冲突、完善征地后相关服务提供新观察。研究发现:1土地是否被征用确实存在着农户总收入效应和非农收入效应,被征地农户比未被征地农户总收入和非农收入显著高出19.6%和9.1%,使用OLS回归方法低估了土地征用对农户收入的促进作用,大致低估了11%,这为政府征地的合理性提供了农户收入佐证。2征地比例并不存在总收入效应和非农收入效应,被征地农户并不是被征地越多收入就会越高,但却会显著降低失地农户的农业收入,大致降低了81%,因而还要认识到土地征用对农户收入的有限性作用,打破土地征用的农户收入神话。3结合当前土地征用实践表明,过分强调土地征用农户收入效应并不能根除征地冲突和矛盾,一方面,要通过多元化就业渠道、多源化收入来源以及多样性社会保障制度避免了被征地农户"失地失业",提高被征地农户增收能力和收入水平。另一方面,更要强调征地程序公平合法,完善土地征用制度底层设计,加强对健康状况差、低收入等贫弱群体的保障,提升被征地农户人力资本和优化就业分布状态,使被征地农户能够顺利完成职业转换。
