TD-RAPD技术用于罂粟品种鉴定初探

目的探索TD-RAPD技术用于罂粟品种鉴定的可行性。方法采用改良CTAB法从罂粟叶片中提取DNA;TD-RAPD技术对种植于云南西双版纳地区的1个罂粟样品进行扩增分析。结果建立了罂粟DNA提取方法,从10个随机引物中筛选出6个引物用于罂粟TD-RAPD分析。结论TD-RAPD技术可用于罂粟DNA的分子标记,为罂粟DNA数据库建立提供技术方法,最终从DNA分子水平上追溯罂粟植物毒源。

Portable high‐resolution automated 3D imaging for footwear and tire impression capture

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners.     

Railway Sector Reform in China: controversy and problems

The railway sector in China has undergone several major rounds of reform and institutional restructuring since 1986. These reform initiatives have largely been unsuccessful due to strong resistance from vested interest groups. The development of China's railway sector has raised some challenging issues that include the centralization of power in the Ministry of Railways (MOR), state monopoly control, rampant corruption and the accumulation of a huge debt burden. The 2013 railway reform initiatives have provided very little in the way of concrete measures to deal with these thorny issues but have instead created more controversy and problems in an already crisis-ridden sector. For the railway industry, the transformation from the mixed-function MOR to a monopolistic China Railway Corporation (CRC) will not necessarily lead to better railway management.

监狱行刑的理念冲突和契合

监狱行刑理念是监狱行刑活动的灵魂,是监狱行刑的内在精神和最高原理,对监狱行刑的趋向性起着指引和引导作用。从当前我国监狱的行刑工作考察,主要存在监狱行刑的功能、罪犯权利保障、监狱行刑的模式等方面的理念冲突,影响制约着监狱行刑的文明化、法治化。监狱的行刑理念采用国际标准还是国内标准或是折衷标准,应该和我国的社会主义市场经济、政治民主和思想文化意识结合起来,综合各因素的共性,切中监狱行刑的契合点,建构适合我国国情的监狱行刑理念。     

略论我国的综合执法

我国长期以来构建的是"全能政府",同时又缺乏严密的组织法规范,行政职能部门设置随意,导致了我国现在的行政机构林立却又权责不清、行政执法政出多门却往往执行不力等不正常现象,严重地影响了行政效率,也不利于相对人合法权益的保护.对于此,我国的<行政处罚法>和<行政许可法>试图通过设立综合执法制度来解决这些问题.近几年来,我国各地的综合执法机关越来越普遍,文章结合实践,对综合执法的含义、产生、作用、形式等问题及其发展模式试作一些粗浅的探讨.     

先秦文士政治人格探析

先秦文士是中国历史中的一个特定的阶层。在特定的历史文化时空中,先秦文士通过政治社会化形成了独特的政治人格,这对其政治行为、政治品质、政治思想、政治价值乃至对整个社会都产生了重要的影响。分析先秦文士的政治人格,阐释在传统政治文化环境中文士与社会的关系及其对当代的影响,会对当今人文知识分子人格构建有所启示。
