新时期我国粮食安全问题研究

粮食安全是国家安全战略的重要组成部分,是保持国民经济健康、持续、快速发展的重要保障。影响我国粮食安全的主要问题多种多样,必须在认真分析的基础上加以解决。确保我国粮食安全的主要对策是要适应新形势,树立新型粮食安全观念;要切实保护耕地,提高农民种粮积极性;因地制宜,不断优化粮食生产的区域布局;以农业科技为支撑,不断提高粮食综合生产能力;深化粮食流通体制改革,建立新型粮食流通体系;加强粮食宏观调控,确保国家粮食安全。     

Bromadiolone poisoning: LC-MS method and pharmacokinetic data

Abstract:  Poisoning with superwarfarins, like bromadiolone, is a growing public health problem, and the mortality is high. Pharmacokinetic data on bromadiolone in humans are however scarce, and there are no reports following repeated exposures to bromadiolone. We have developed a method for quantification of bromadiolone in whole blood, using liquid chromatography–mass spectrometry (LC-MS). The analytical method is reported. Limit of detection was 0.005 mg/L and limit of quantification was 0.01 mg/L. The concentrations of bromadiolone in whole blood and plasma in serial samples from a 62-year-old woman were measured. The half-life of bromadiolone in blood was estimated to be about 6 days in the initial phase of elimination and about 10–13 days in the terminal phase. The mean plasma/blood ratio of bromadiolone was 1.7 ± 0.6. Stability testing of bromadiolone in whole blood samples after two cycles of freeze and thaw revealed that bromadiolone concentrations decreased.     

Participation rationales,regulatory enforcement,and compliance motivations in a voluntary program context

This article extends the study of regulatory compliance motivations from “traditional” regulatory settings to a government-sponsored voluntary one. We argue that the rationale(s) which motivate participants to engage a voluntary program likely shape which motivations drive them toward (or away from) program compliance. Our study examines the possible influence of program participation rationales alongside that of regulatory agents' enforcement styles and strategies. Leveraging a national survey of certified United States Department of Agriculture organic producers, we find that the more a producer pursues organic certification to increase profits, the more likely they are to report deterrent fears as an important compliance motivation. In contrast, the more a producer becomes certified to support the organic movement, the more heavily they weigh a personal sense of duty to comply. We discuss the implications of these, and other, study findings for compliance motivations theory and voluntary program integrity.     

投毒杀人案件侦查取证研究

当前在投毒杀人案件侦查取证中,存在的主要问题是:取证不及时、不全面和缺乏针对性,物证保全不当和送检不及时。针对这些问题,侦查人员在侦查时,应以投毒现场为中心,围绕投毒方法、毒物来源、因果关系、危害后果等全面取证。现场勘查时,除提取常规痕迹外,还要着重提取投毒杀人案件的特有痕迹物证;审讯犯罪嫌疑人时,要设法固定口供;要完善证据体系,学会运用间接证据证明投毒杀人的犯罪事实。     

铊中毒的法医毒理学研究进展

由于铊盐溶液无色无味,且毒性剧烈,所以近年来利用铊盐投毒的案例时有报道。利用铊盐投毒隐匿性强,给案件的侦破带来很大难度,同时也因诊断不及时而耽误治疗。本文结合文献,从中毒方式、毒代动力学、毒理作用、中毒症状、中毒致死量、尸体检查所见、法医学鉴定及鉴别诊断等方面,对铊中毒的法医毒理学研究进展进行综述。     

‘Things are not working now’: poverty,food insecurity and perceptions of corruption in urban Malawi

ABSTRACT

Malawi is one of the world's least urbanised countries, but its cities are growing rapidly and poverty in urban Malawi is becoming a prominent political issue. Food insecurity is a widespread manifestation of urban poverty in Africa, especially in informal settlements. This article is based on in-depth interviews with food insecure residents of Lilongwe’s informal settlements who, when asked why they were food insecure, overwhelmingly pointed to the Cashgate corruption scandal as a cause. There have been many political corruption scandals in Malawi, but the Cashgate scandal, which was revealed in September 2013 and reverberated throughout the political culture, has been among the most prominent and consequential of these scandals. The article seeks to contribute to literature on the political dimensions of urban food security in Africa while also presenting a way of understanding corruption from the point of view of vulnerable people whose lives have been directly and indirectly affected.     

95例尸体血中HbCO％的分析

血中碳氧血红蛋白饱和度(简称HbCO％,下同)含量是判断一氧化碳中毒,推断火灾中尸体生前状态的依据。本文证明:血中HbCO％与其年龄、性别及不同情况下CO中毒有关。一氧化碳中毒的尸体含量较高(平均大于60％);火灾事故中遇难的尸体含量中等(平均在30～50％);而被杀后投入火场或服毒后自焚则较低(平均小于20％)。     

曲马多在家兔体内的死后分布研究

目的研究曲马多在中毒家兔体内死后分布规律,为曲马多中毒检材采取提供实验依据。方法家兔经口给予10倍LD50曲马多,待家兔死亡后迅速解剖取样,气相色谱／质谱联用和气相色谱-FTD法测定其体液、脏器、大脑及右上肢和右下肢肌肉中曲马多的含量,比较其变化规律。结果血液和肝脏中曲马多的最低检出限分别为0．05μg/mL和0．05μg/g,提取回收率为97．60％±0．65％～103．10％±1．24％。曲马多在家兔体内的死后分布为：肾〉胃〉肝〉脾〉肺〉脑〉心〉上肢肌肉〉下肢肌肉〉〉体液（尿〉胆汁、心血〉玻璃体液）。结论大剂量曲马多中毒致死后在体内分布不均匀,组织中曲马多含量明显高于心血、胆汁等体液。     

试述光复初期台鸽粮荒及政府之对策

光复后不久,台湾即遭遇粮荒,主要表现为粮价高昂。粮荒源于日据时期的粮食短缺,主要原因是战争破坏了台湾农业生产的条件。台湾粮食匮乏程度不如大陆严重,但价格高涨,对习于配给而又极少经历粮荒的台湾民众来说,形成巨大的心理震撼和生活压力。台湾省行政长官公署先是沿用日据时期的食粮配给制度,后放弃配给制度,允许粮食自由流通,但采取各种措施加以控制。与此同时,政府积极洽购粮食和肥料,试图增加粮产缓解粮荒。长官公署的种种措施有利于缓解粮荒。
