徇私舞弊不移交刑事案件罪若干问题探析

现行刑法规定徇私舞弊不移交刑事案件罪之后,理论及实践中对该罪的主客观要件等基本问题的争议甚多,对该罪的罪名、罪状、法定型的修订建议更是歧见迭出.文章首先根据现行立法对该罪的基本构成的相关要件进行了全面阐述,探讨了该罪在立法领域的缺陷,建议将本罪罪名更改为"故意不移交刑事案件罪",在基本构成要件中取消"徇私舞弊"和"情节严重"的规定,在规定基本法定型的基础上,规定升格法定型并明确其构成条件,总体上提高本罪之法定型.     

Comparative physical mapping of rice BAC clones linked to resistance genes Glh,Bph-3 and xa-5 in Oryza sativa L. and O. granulata Nees et Arn. ex Watt.

Oryza granulata Nees et Arn. ex Watt. is one of the three wild relatives of rice,which are the most valuable for study and utilization in China.In this study,the homology and physical locations of three rice resistance genes,Glh,Bph-3 and xa-5 are comparatively analyzed between O.sativa and O. granulata by Southern blotting and fluorescence in situ hybridization (FISH).The results of Southern blotting indicate that there exist homologous sequences of the tested RFLP markers in O. granulata.By using three bacterial artificial chromosome (BAC) clones scanned by the tested RFLP as probes, FISH signals are detected on both mitotic and pachytene chromosomes in O.sativa and O.granulata.Dual-color FISH demonstrates that two of the three BAC clones (14E16 and 38J9) are located on the short arm of the same chromosome pair in O. granulata. Additionally, colinearity is shown for the two clones between O.sativa and O.granulata. Another BAC clone 44B4 is located on the end of the short arm of other chromosome pair in these two species.Although the phylogenetic relationship between O.sativa and O.granulata is the most distinct in Oryza and these two species have evidently different biological features and ecological habits, the relative lengths and arm ratios of the detected chromosomes and the relative positions of the tested clone signals on chromosomes in O. granulata are quite similar to those in O. sativa.

区域创新网络知识溢出效应研究

区域创新网络内正式或非正式互动学习的存在 ,使网络内部各个成员的研究开发活动产生知识溢出效应。通过建立知识溢出效应模型 ,认为区域创新网络中知识溢出呈现螺旋上升态势 ;知识溢出带来区域集聚经济、规模经济形成的同时也造成区域产品雷同化和网络内部企业的竞争加剧。解决问题的有效途径是将知识溢出效应的外部性内在化 ,通过某种方式将外部收益或成本内含于某种经济关系中。内在化的过程就是使个别厂商的成本与社会成本相等的过程 ,也是通过外力对企业生产函数调整的过程。具体实施方式主要包括政府干预、产权制度安排和道德约束     

三车道元胞自动机交通流模型研究

在Nagel-Schrekenberg（NS）元胞自动机交通流模型的基础上，提出了一种高速公路三车道元胞自动机交通流模型．该模型中所有的车辆均遵循相同的演化规则，并允许车辆以一定概率换道．根据计算机数值模拟．研究了车辆减速概率、换道概率对车流量、车道利用率影响关系，结果表明，在相同情况下，此模型所得到的基本图显示出交通流量比单车道NS模型大，并且发现减少不必要的车辆换道行为可以使驾驶更安全．这些研究为管理三车道的道路系统提供了一定的参考依据．

The Intelligent Decision Support System Model of SARS

Based on the intelligent decision support system, a new method was presented to defense the catastrophic infectious disease such as SARS, Bird Flu, etc.. By using All Set theory, the decision support system (DSS) model can be built to analyze the noise information and forecast the trend of the catastrophe then to give the method or policy to defend the disease. The model system is composed of four subsystems: the noise analysis subsystem, forecast and simulation subsystem, diagnosis subsystem and second recovery subsystem. They are discussed briefly in this paper. This model can be used not only for SARS but also for other paroxysmal accidences.     

园林照明对窄叶石楠光合指标的影响

为得出园林照明对园林植物光合指标的影响,对园林植物窄叶石楠(Photiniaserrulata)进行5种不同光谱的发光二极管(LED)照射,每种光谱设置3级光照强度,并测量植物净光合速率及植物光合有效辐射.结果表明:相同光照强度,天然光照下植物的光合有效辐射最高;人工光源照射下,窄叶石楠净光合速率随光照强度升高而升高;绿光LED(530nm)照射,植物的光合有效辐射随光照强度增高,但净光合速率始终为负.     

Integrated heat and power dispatch model for wind-CHP system with solid heat storage device based on robust stochastic theory

This paper built a combined heat and power (CHP) dispatch model for wind-CHP system with solid heat storage device (SHS) aiming at minimizing system coal consumption, and set system demand-supply balance and units’ operation conditions as the operation constraints. Furthermore, robust stochastic optimization theory was used to describe wind power output uncertainty. The simulation result showed that SHS increased CHP peak-valley shifting capability and reduced abandoned wind rate from 12% to 6%, and reduced 5% coal consumption, compared with the original system operation by flexible charging electric power and heating. The payback period of employing SHS in wind-CHP system is far shorter than SHS expected service life.
