论经济法在社会分配中的作用和边界

由于分配与法律之间的密切关系所决定,经济法在社会分配过程中具有特殊的地位和作用。但是,应对极具复杂性的社会分配问题,经济法在调整社会分配关系时,既面临着发生在国家、企业与个人之间的分配关系的范围限制,也面临着来自于政府有限理性以及预算、税收和财政支出等调整方法方面的局限。因此,经济法在社会分配中的作用和边界问题值得关注与重视。     

A Direct Aqueous Derivatization GSMS Method for Determining Benzoylecgonine Concentrations in Human Urine

A sensitive and reliable method for extraction and quantification of benzoylecgonine (BZE) and cocaine (COC) in urine is presented. Propyl‐chloroformate was used as derivatizing agent, and it was directly added to the urine sample: the propyl derivative and COC were then recovered by liquid–liquid extraction procedure. Gas chromatography–mass spectrometry was used to detect the analytes in selected ion monitoring mode. The method proved to be precise for BZE and COC both in term of intraday and interday analysis, with a coefficient of variation (CV) <6%. Limits of detection (LOD) were 2.7 ng/mL for BZE and 1.4 ng/mL for COC. The calibration curve showed a linear relationship for BZE and COC (r² >0.999 and >0.997, respectively) within the range investigated. The method, applied to thirty authentic samples, showed to be very simple, fast, and reliable, so it can be easily applied in routine analysis for the quantification of BZE and COC in urine samples.     

Correlation Between Average Tissue Depth Data and Quantitative Accuracy of Forensic Craniofacial Reconstructions Measured by Geometric Surface Comparison Method

Accuracy is the most important factor supporting the reliability of forensic facial reconstruction (FFR) comparing to the corresponding actual face. A number of methods have been employed to evaluate objective accuracy of FFR. Recently, it has been attempted that the degree of resemblance between computer‐generated FFR and actual face is measured by geometric surface comparison method. In this study, three FFRs were produced employing live adult Korean subjects and three‐dimensional computerized modeling software. The deviations of the facial surfaces between the FFR and the head scan CT of the corresponding subject were analyzed in reverse modeling software. The results were compared with those from a previous study which applied the same methodology as this study except average facial soft tissue depth dataset. Three FFRs of this study that applied updated dataset demonstrated lesser deviation errors between the facial surfaces of the FFR and corresponding subject than those from the previous study. The results proposed that appropriate average tissue depth data are important to increase quantitative accuracy of FFR.     

尼龙植绒拭子与棉拭子血痕DNA分型效果比较

目的探讨尼龙植绒拭子与棉拭子血痕DNA分型检验的效果。方法取抗凝全血用去离子水倍量稀释2、4、8、16、32、64、128倍,各取1μL分别滴加于尼龙植绒拭子与棉拭子头部,干燥制成血痕,应用Chelex-100提取每个浓度两种材质拭子的血痕样本DNA,采用Identifiler Plus试剂盒进行复合扩增,3500XL型遗传分析仪进行检测,对比各组DNA分型检验成功率。结果 1检验成功率:稀释16~64倍尼龙植绒拭子血痕均明显高于相同稀释倍数的棉拭子血痕(P0.001);其余浓度血痕两种材质拭子的检验成功率无明显差异;2分型图谱峰高和均衡性:不同浓度尼龙植绒拭子血痕峰高多为棉拭子血痕的2倍以上,16~64倍稀释血痕尼龙植绒拭子均衡性更好。结论尼龙植绒血痕拭子的检验效果优于棉拭子血痕,在微量血痕检验时优势更明显。     

绵羊与藏羊脑静脉系统整体铸型制作方法的建立

为了获得完整的脑部静脉血管通路塑料模型,经过反复试验,首次建立了脑静脉血管系统的整体铸型方法。选择新鲜的藏羊和绵羊头各15个,将用丙酮和丁酮稀释的200g/L ABS(丙烯腈、丁二烯、苯乙烯三元共聚塑料)溶液经上颌静脉灌入脑静脉窦及脑静脉血管内,经2～3d后,等待ABS溶液完全凝固时,用盐酸腐蚀掉脑、脑膜以及构成颅腔的颅骨,然后对血管铸型进行冲洗和修整。获得了完整的脑部静脉血管系统立体铸型。该铸型标本能够清楚地显示脑静脉窦和血管的位置、走向、管径及其相互之间的关系,同时还能够清晰地显示出颅内外静脉血管之间的联系。该方法的建立使整体展现脑内静脉血管系统成为现实,也为进一步深入研究脑静脉系统奠定了基础。     

侵犯商业秘密罪中“重大损失”的认定问题

侵犯商业秘密行为极大地破坏了公平诚信的市场竞争秩序。为此,我国的立法和司法均加强了对商业秘密的保护。由于侵犯商业秘密罪被立法规制为结果犯,因此“重大损失”作为区分罪与非罪的重要标准,一直备受关注,加上立法和相关司法解释没有对“重大损失”的计算问题予以明确,故理论界和实务界的争议较大,影响了对侵犯商业秘密行为的打击力度。从“重大损失”的地位、内容、计算方法三方面对该问题进行探索,可以对立法和司法有所裨益。     

JAVA程序设计课程教学改革与实践

在公安院校JAVA程序设计课实际教学中,授课教师普遍感觉教学难度大,学生普遍感觉学习起来吃力,难以掌握和应用。这需要课程教师在教学内容、教学方法以及培养学生实际操作能力方面进行一些探索和实践。
