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.

乡风文明建设的理论探究与现实思考

党和国家明确提出了建设社会主义新农村的五项指标,其中,“乡风文明”和“村容整洁”共同构成社会主义新农村的内在和外在形象。乡风是否文明直接关系到建设社会主义新农村的进程。“乡风文明”包含在“社会主义精神文明建设”和“中国特色社会主义文化建设”的活动内容之中。因此,要加大精神文明建设的力度,大力发展社会主义先进文化,为建设社会主义新农村、构建和谐社会提供强大的精神支撑,促进农村经济社会的协调发展。     

浅谈朝核问题六方会谈中的中国国家利益

国家利益一词历来是理解政府目标和政策的关键,“每个政府在面对他国的情况下都要为维护和增强本国的利益而采取行动。”[1]在处理朝鲜核危机中,中国采取了“积极介入”姿态,发起并推动朝核问题六方会谈,积极参与“国际管理”,这是中国外交史上一次有转折意义的事件。本文试就和平解决朝核问题——六方会谈中的中国国家利益进行简要分类和界定。     

"传统"与"现代"的对话:论遗传资源获取及惠益分享与知识产权

信息社会中随着研究视角从"文化多样性"深入到"遗传多样性"领域,遗传资源荻取及惠益分享与知识产权的法律问题得到彰显.其根本冲突主要表现在三个层面:传统知识与原有知识产权保护体系的协调;遗传资源提供方与利用方的利益协调;经济利益与环境利益矛盾冲突的协调.就主体要件而言,群体主义权利主体模式具有可行性;就程序要件而言,事先知情同意规则、许可规则、来源地规则具有必要性;就知识产权体系下的惠益分享方式而言,积极参与具体研发过程具有战略性.在调整遗传资源与知识产权的诸多利益关系过程中,需要警惕四大风险:知识产权过度扩张而导致"反公有物悲剧";知识产权成为利益集团谋求私利工具并危害公共福利:利益分配新失衡致使"弱势主体"再次错失发展机遇;以牺牲环境利益为代价的技术开发.
