The Impact of Mobile Phone Technology on Agricultural Extension Services Delivery: Evidence from India

This study examines the impact of mobile phone enhanced intervention in agricultural extension service delivery in India. Findings show that the amount, quality and speed of service delivery have improved significantly because of the intervention. There are also benefits in terms of greater knowledge and awareness of new agricultural practices, farmers’ aspiration to try new technology in the future and access to credit. The system does not discriminate against farmers from disadvantaged and low education backgrounds. Thus, a system of well-used technology, which is assisted by trained village youths, can serve as a tool for inclusive development.

2014: A Turning Point in the Global Order

The issues of war and peace captured international attention in 2014.It was the centennial of World War I,and the focus was on tensions in Asia for the first half of the year.One radical Western view went so far as to compare today’s China to pre-war Germany in the midst of rapid economic growth,rising nationalism and a beefed up military.The hype about Beijing’s alleged regional expansion peaked at the Shangri-La Security Forum(Singapore)in May 2014.However,events on the ground proved such glib accusations wrong.In October 2014,this author accompanied several other Chinese scholars in a visit to seven U.S.think tanks.Our American hosts were not worried     

液相色谱-串联质谱法检测生物样品中百草枯及其代谢物

目的建立生物样品中百草枯(paraquat,PQ)及其2种主要代谢物monoquat,paraquatmonopyridone(MP)的液相色谱-串联质谱(LC-MS/MS)检测方法,应用于百草枯中毒案件的法医学鉴定。方法生物样品经乙腈或甲醇沉淀蛋白,使用Agilent HILIC Plus(4.6×100mm,3.5μm)色谱柱,以0.1%甲酸水溶液～0.1%甲酸乙腈溶液(v/v)为流动相进行洗脱,在多反应监测模式下检测。结果百草枯及其代谢物在1～1000ng/mL内线性关系良好,相关系数(r)≥0.9996,最低检出限为0.34～6.00ng/mL,检测准确度为91.25%～113.44%,日内及日间精密度分别为1.51%～3.99%和1.92%～4.93%。结论本文建立的LC-MS/MS法具有灵敏度高、特异性好的特点,可应用于百草枯中毒相关案件的法医学鉴定。     

家兔死后体内2-氨基噻唑啉-4-羧酸分布研究

目的 建立家兔氰化钾灌胃给药致死动物模型,研究氰化物代谢物2-氨基噻唑啉-4-羧酸(ATCA)在家兔体内的死后分布规律.方法 雄性家兔7只(体重约2.0kg～2.5kg)经口灌胃2LD50(10mg/kg)氰化钾水溶液,观察家兔反应,待家兔呼吸、心跳和反射全部消失后立即对家兔进行解剖取心、肝、脾、肺、肾、脑、睾丸、胃壁...     

公益诉讼：社会保障权救济的新路径

社会保障权是社会成员从国家和社会获得基本物质条件或相关服务、保障其基本生活水准和维护人之尊严的权利。社会保障权以社会本位为价值目标,社会保障权具有公益属性。传统三大诉讼救济社会保障权存在障碍,公益诉讼作为维护社会公共利益之诉,在诉讼目标、功能、原告资格与民主法治精神方面与社会保障权救济具有契合性。社会保障权公益诉讼需扩大原告资格与受案范围,赋予当事人诉权,合理分担举证责任与诉讼费用,构建激约机制,运用多元化的法律责任,充分发挥法官的司法能动作用。     

我国盐业管制制度改革的路径选择

目前,社会各界主要提出放松盐业管制、坚持食盐专营和强化食盐专营三种盐业体制改革主张。文章基于“管制治理—管制激励—管制绩效”的管制制度分析范式,采用规范分析与实证分析相结合的方法,运用新制度经济学理论、代理理论和福利经济理论等,通过对以上三种管制改革路径的优化,认为盐业社会性管制不可行、食盐专营制度不可续、国家专营制度不可取,筛选出我国盐业管制制度的次优改革路径——盐业特许投标制度,并设计出激励兼容的特许投标政策和特许投标治理体制,以期为我国盐业体制改革提供智力支撑和决策参考。
