德国法学教育述评

21世纪德国法学教育改革的重点是:加快培养过程的现代化和授课形式的多样化;通过优化录取和优化培养,提高学生质量和提高国际竞争力。学者建议:授予法学士学位(前提:修满6个学期的课程),以此取代到目前为止所实行的定向和中期考试;可提前用笔试和口试的形式进行第一次国家考试中的主科考试(如刑法或公法);从第5学期开始,深化通选课的学习;将第一次国家考试的校内考核比例确定为40%(5%为基础课,35%为重点课);将部分教学管理的决策权下放到院系;引入硕士学位课,以补充。     

当代公共管理研究的范式观--一项经验研究

以经验事实为依据,勾画出了指导当代美国公共管理研究的范式观.在经验分析的基础上,作者认为,有关公共管理领域是否具有知识核心及其与学科的发展之间的相关性的争论正越来越不重要,因为答案已经显现.重要的是从事公共管理研究的学者应具有清醒的学科自我意识以及对现有的范式有更为清晰的把握.公共管理学科对本领域的常规科学研究活动的自觉意识能够给本学科提供更为清晰的研究焦点,能够提升澄清谬见的敏锐性,进而推动公共管理理论的发展.     

Eyeball Position in Facial Approximation: Accuracy of Methods for Predicting Globe Positioning in Lateral View

This study measured the accuracy of traditional and validated newly proposed methods for globe positioning in lateral view. Eighty lateral head cephalograms of adult subjects from Central Europe were taken, and the actual and predicted dimensions were compared. The anteroposterior eyeball position was estimated as the most accurate method based on the proportion of the orbital height (SEE = 1.9 mm) and was followed by the “tangent to the iris method” showing SEE = 2.4 mm. The traditional “tangent to the cornea method” underestimated the eyeball projection by SEE = 5.8 mm. Concerning the superoinferior eyeball position, the results showed a deviation from a central to a more superior position by 0.3 mm, on average, and the traditional method of central positioning of the globe could not be rejected as inaccurate (SEE = 0.3 mm). Based on regression analyzes or proportionality of the orbital height, the SEE = 2.1 mm.     

多种判定方法在半同胞姐妹关系鉴定中的综合应用

目的探讨综合运用三种不同方法进行半同胞姐妹关系的鉴定。方法对案例中的甲、甲母、乙和乙母分别使用Power Plex21试剂盒、AGCU Expressmarker 21+1试剂盒、Microreader 23sp-B试剂盒和AGCU X-19 STR试剂盒进行STR分型,根据STR分型结果分别利用ITO方法、判别函数法和IBS法进行半同胞关系鉴定。同时结合X-STR结果,进而综合判定是否为同父异母半同胞姐妹亲缘关系。结果本案例中通过ITO方法计算,HSI均在1.36×102~2.09×105之间,支持甲和乙为半同胞关系,判别函数同样得到了基本一致的结果,IBS法的结果也对此结果进行了验证。结论对于同父异母的半同胞关系鉴定,综合应用多种判定方法分析可获得较为可靠的鉴定意见。     

Comparison of Catalytic and Immunological Amylase Tests for Identifying of Saliva from Degraded Samples

The stability of salivary α‐amylase is a critical factor in both catalytic and immunological method‐based forensic saliva identification. This study aimed to assess the sensitivity of catalytic and immunological tests on degraded saliva samples. Degraded saliva stains were prepared by microbial decomposition using humid soil. Salivary α‐amylase activity was catalytically detected both qualitatively and quantitatively using the Phadebas^® amylase test. As immunological methods, we conducted qualitative and quantitative tests using the RSID?‐saliva test and ELISA, respectively. Salivary α‐amylase activity of degraded samples (incubated at 37°C for 12 h) was significantly lower than that of controls in the quantitative tests. All the degraded samples obtained by the humid soil produced negative results in the Phadebas^® tests, but showed positive results in the RSID?‐saliva test and ELISA. These results suggest that immunological tests are effective for testing degraded saliva samples that have lost their enzymatic activity.

该文对姬松茸液体发酵条件进行了研究。考察了发酵时间对姬松茸液体发酵的影响,确定最佳发酵周期为9天.对发酵培养基中葡萄糖、豆粕及麸皮这三个组分选择了三水平进行正交试验、方差分析。结果表明发酵培养基中葡萄糖组分对姬松茸生物量的影响极显著。最优培养基组合为葡萄糖3%,麸皮1.5%,豆粕1.5%。按最优培养基组合进行发酵试验,姬松茸生物量可达到最高值8.576 g/L。     

A method for enhancing gunshot residue patterns on dark and multicolored fabrics compared with the modified Griess test

In using infrared or infrared-enhanced photography to examine gunshot residue (GSR) on dark-colored clothing, the GSR particles are microscopically examined directly on the fabric followed by the modified Griess test (MGT) for nitrites. In conducting the MGT, the GSR is transferred to treated photographic paper for visualization. A positive reaction yields an orange color on specially treated photographic paper. The examiner also evaluates the size of the powder pattern based on the distribution of nitrite reaction sites or density. A false-positive reaction can occur using the MGT due to contaminants or dyes that produce an orange cloud reaction as well. A method for enhancing visualization of the pattern produced by burned and partially unburned powder is by treatment of the fabric with a solution of sodium hypochlorite. In order to evaluate the results of sodium hypochlorite treatment for GSR visualization, the MGT was used as a reference pattern. Enhancing GSR patterns on dark or multicolored clothing was performed by treating the fabric with an application of 5.25% solution of sodium hypochlorite. Bleaching the dyes in the fabric enhances visualization of the GSR pattern by eliminating the background color. Some dyes are not affected by sodium hypochlorite; therefore, bleaching may not enhance the GSR patterns in some fabrics. Sodium hypochlorite provides the investigator with a method for enhancing GSR patterns directly on the fabric. However, this study is not intended to act as a substitute for the MGT or Sodium Rhodizonate test.

检测丁丙诺啡的胶体金标记单克隆抗体免疫试剂盒研制

目的采用免疫竞争法原理,建立一种简便快速检测丁丙诺啡的方法。方法将20nm胶体金颗粒标记的抗丁丙诺啡单克隆抗体,均匀浸在吸水玻璃纤维上,将丁丙诺啡-BSA和纯化后的羊抗鼠IgG多克隆抗体在硝酸纤维薄膜分别划1mm宽的检测线(T线)和质控线(C线),制成丁丙诺啡胶体金标记单克隆抗体免疫层析检测条,并组装成检测板。结果以GC/MS为标准对照,100例样品检测结果显示,本检测板的准确率为99.0%。丁丙诺啡胶体金标记单克隆抗体免疫层析检测板在对45种药(毒)物的测试中,仅识别丁丙诺啡及其主要代谢产物。结论丁丙诺啡胶体金标记单克隆抗体免疫层析检测板在5min内可检出样品中的丁丙诺啡及其代谢物,检测丁丙诺啡的阈值为100ng/mL。     

单亲亲子鉴定的分析研究

目的从理论和实际应用方面客观评价13～15个STR位点应用于单亲亲子鉴定的准确性。方法依据中国人群基因频率资料,计算单亲亲子鉴定的非父排除率及单亲亲子鉴定的亲子关系概率,并选择有明确排除结论的104例排除案例,分析统计其中父-子二联体出现的排除指标数。结果对于单亲亲子鉴定,选用13～15个STR位点,联合非父排除率为0.9805～0.9906;亲子关系概率均大于99.73%。104例二联体排除案例中,有3例的排除指标数小于2,未发现排除指标为零的现象。结论若应用ProfilerPlus和CofilerPlus试剂盒的13个STR位点进行日常单亲亲子鉴定工作,存在微弱漏判非父的风险,必要时增加检测指标数。不排除案例的单亲亲子鉴定,其亲子概率均可达国际认定标准。
