Research on Prosecution Limitation of Environmental Crime in China [PDF]
, 2016 生态环境是人类生存的基础，我国在1997年修订刑法时增设了破坏环境资源保护罪，但仅对常见的环境犯罪种类加以规定。追诉时效制度是刑法中重要制度之一，决定了追诉权及求刑权的取得与消灭，具有重要价值。环境犯罪作为刑事犯罪的一种，应当适用我国追诉时效制度，然而，由于环境犯罪存在特殊性，且我国刑法对于环境犯罪追诉时效制度的规定不明确，目前学界针对环境犯罪相关问题存在争议，导致现有追诉时效制度在适用于环境犯罪时，存在追诉时效起算点不易判断、追诉时效较短、无法适用超期追诉程序，以及当行为主体为单位时无法追诉等问题 ...

A Positive Research on Convictive Standard of Illegal Fund-Raising [PDF]
, 2016 如何界定非法集资犯罪，也即非法吸收公众存款罪和集资诈骗罪的定罪标准，是非法集资犯罪最为核心的问题，也是学界一直关注但尚未完全解决的问题。目前学界对非法集资定罪的研究，集中体现在立法上为非法吸收公众存款罪的入罪标准提出修正建议，以及在司法上为明晰两罪的构成要件提供解决思路。但立法建议空有逻辑自洽却缺乏可操作性，对认定标准的阐释也并未使模糊的构成要件变得清晰，现有的研究并未对立法及司法发挥应有的指导作用。究其原因，在于研究方法上固守价值分析和教义学的规范研究，试图从价值或规范本身理解规范的应然状态。但是 ...

Feasibility study of utilizing multi-biomarkers in Sebastiscus marmoratus to monitor marine combined pollution [PDF]
, 2015 生物标志物检测技术具有效应快、灵敏度高和特异性强的优点，已广泛应用于细菌、寄生虫、病毒等方面的定性检测。但目前对于生物标志物的研究以室内为主，现场应用较少。许多在室内研究中与污染物有较好相关性的生物标志物在现场应用中却不甚理想。因此，将室内研究结果推广到现场检测研究具有十分重要的意义。 在复杂的海洋环境中，单一生物标志物只能从某一层面反应污染物的生物效应，建立一套多生物标志物的生物检测技术就显得尤为重要。综合生物标志物响应指数法(Integratedbiomarkerresponse，IBR ...
