2012-2013年北京市海淀区放射卫生量化分级监督管理情况对比分析

找出北京市海淀区内开展放射诊疗工作的医疗机构在放射卫生管理中存在的问题,并为下一阶段海淀区卫生监督所的监督管理重点指明方向。方法：采用普查的方法,于2012年和2013年,用自制的《北京市海淀区医疗机构放射卫生量化分级表》对辖区内已取得《放射诊疗许可证》且开展放射诊疗活动的医疗机构进行量化评级。结果：（1）2012年和2013年分别调查了269和257家医疗机构。与2012年相比,2013年A级单位所占比例由30.1%提高到了72.0%;C级和D级单位数和构成比都有了很大程度的下降,差异具有统计学意义。（2）一级以下医疗机构中A级单位增加的比例和三级医疗机构C级单位减少的比例最大。一级及以下级别的医疗机构中的C、D级单位数占全部医疗机构的比例最大。（3）2012年量化分级情况中,卫生管理、放射人员证和工作场所三个大项合格率较低,合格率分别为56.5%、61.0%和64.7%;而2013年这三项的合格率均得到较大提高,分别为81.3%、81.0%和83.7%。（4）除个人剂量检测管理和建设项目管理的合格率分别为71.6%和70.8%外,2013年其他八项管理项目的合格率均达到80%以上。结论：三级和一级以下医疗机构实行量化分级监督管理最有成效;2013年海淀区放射卫生合格率反映出个人剂量检测和建设项目管理为下一年的监督管理重点。     

治安管理处罚证明标准的构建

我国的《治安管理处罚法》未规定治安处罚的证明标准,加之行政诉讼的司法审查标准也不明确,致使公安机关在治安执法中难以正确收集证据对违法事实做出认定,乃至在行政诉讼中屡屡败诉.本文认为,我国的治安处罚应采用"优势证据"标准和"排除合理怀疑"证明标准的分层次标准.     

The Optimal Combination of Cartilage Source and Apparatus for Long‐Term In Vitro Chondrocyte Viability Analysis

Abstract: Most studies of long‐term chondrocytes survival were for tissue banks. They showed a gradual reduction in the viable chondrocytes percentage as a function of time and ambient temperature, but the samples were harvested under optimal conditions. The aim of our study was to determine the most reliable combination of cartilage source and assay for the in vitro postmortem chondrocyte viability analysis in the conditions that imitate a dead body. Osteochondral cylinders were procured from femoral condyles and talar trochleas of three male donors and stored in the cell culture media at 4 ± 2°C and 23 ± 2°C. The samples were analyzed by a cell viability analyzer and a confocal laser scanning microscope (CLSM) initially 24–36 h after death and then in 4‐week intervals. The results reconfirmed the significant influence of time (p = 0.0002), but not of the temperature (p = 0.237). The largest reproducibility was presented for the knee joint and the CLSM.

Analyzing the uncertainty of simulation results in accident reconstruction with Response Surface Methodology

This paper is focused on the uncertainty of simulation results in accident reconstruction. The Upper and Lower Bound Method (ULM) and the Finite Difference Method (FDM), which can be easily applied in this field, are introduced firstly; the Response Surface Methodology (RSM) is then introduced into this field as an alternative methodology. In RSM, a sample set is firstly generated via uniform design; secondly, experiments are conducted according to the sample set with the help of simulation methods; thirdly, a response surface model is determined through regression analysis; finally, the uncertainty of simulation results can be analyzed using a combination of the response surface model and existing uncertainty analysis methods. It is later discussed in detail how to generate a sample set, how to calculate the range of simulation results and how to analyze the parameter sensitivity in RSM. Finally, the feasibility of RSM is validated by five cases. Moreover, the applicability of RSM, ULM and FDM in analyzing the uncertainty of simulation results is studied; the phenomena that ULM and FDM can hardly work while RSM can is found in the latter two cases. After an analysis of these five cases and the number of simulation runs required for each method, both advantages and disadvantages of these uncertainty analysis methods are indicated.     

城市管理综合行政执法体制、机制创新的法理学思考——以安徽省城市管理行政执法为例

城市管理综合行政执法自建立以来,一定程度上缓解了多头执法、执法交叉、效率低下问题,但也存在的范围过窄、事权错位、处罚公信力下降等现象。为了解决这些矛盾,各地纷纷进行了诸如相对集中行政处罚权范围进一步扩大,城管综合行政执法权进一步下移,重大行政处罚群众公议等一系列体制、机制创新。这些创新在现实中取得了一定的成效,但同时也面临着合法性和合理性的质疑。为了完善创新,务必正确理解创新与法治政府建设的关系,通过完善立法,破解城管行政执法体制、机制创新的无序状态,建立专家参与与公民主体相结合的程序机制,促进体制、机制创新更加合法、合理。

消费增长与财政政策取向

促进消费稳定增长,是我国财政政策的着眼点之一。由于居民收入不确定性因素的增加、收入差距过大和个人所得税不完善、税收政策偏重于向投资倾斜、财政支出结构不合理等因素的综合作用,我国居民消费率偏低,投资与消费的矛盾不断加剧。因此,必须调整财政政策,树立正确的财政指导思想,优化税制,完善社会保障与复式预算制度,调整财政支出结构,实现财政政策的政策性转变。
