法律规范的权威定义及结构理论之质疑

现有法律规范的权威定义受制于反映论的认识进路,不仅未能全面揭示法律规范的内在含义,而且在属概念不明之时,自身也晦暗不清。法律规范的概念可以界定为法律文本中表述某主体在一定条件下对其他主体就某客体当为某类行为的条文所表示的意义。以此定义观之,在现有法律规范权威定义框架下建构的法律规范结构理论,论述的其实是复数法律规范间的复合结构,而不是法律规范的结构。     

美国三权分立制度与我国议行合一制度之比较

由于历史、文化和社会条件等的差异,不同的国家所实施的国家管理形式会不相同。美国实行三权分立政治制度,中国实行的是议行合一政治体制。抑恶功能是前者的价值理念,扬善功能是后者的价值理念。它们在实践中都有所长,有所短,需要相互借鉴,取长补短。     

注重考试环节提高教学质量

考试是教学的重要环节,不同的学科、不同的课程有不同的特点。命题应严格遵循全面考核,突出重点,理论联系实际,注重考查学生的实务操作能力这一原则。在试题内容上,应难易适度;在阅卷方式上,应根据题型的不同采用不同的判分标准;在应试技巧上,应教导学生要懂、吃透基础知识,学会总结典型题型。同时应加强学生考前模拟训练。     

当代未成年人情感观现状与特点——对安徽省八城市未成年人的调查分析

对安徽省八城市未成年人的情感观的调查发现,父母、同学、朋友对未成年人影响很大,老师、兄弟姐妹影响较小。其情感表现出传承性、幼稚性、含混性等特点,与20世纪90年代未成年人相比,其情感取向更趋于功利,更具有不确定性和独立性。教育策略是加强对他们的"三观"教育,强化成年人的榜样作用并发挥社会舆论的导向作用。

陕西省级人才政策分析与评价

随着我国"一带一路"倡议和新西部大开发部署的推进,陕西省人才政策能否满足自身发展的需要值得研究。本文综合运用政策文本分析方法,对陕西省2008-2020年间颁布的101件省级人才政策文本特征属性进行量化分析。研究发现,陕西省级人才政策的文种类型多样、发文单位较广、年发文量呈波动变化。通过主题词分析,可将省级人才政策划分为初始、发展和巩固三个阶段,不同阶段的政策侧重点有差异。人才政策工具以环境型政策工具为主、供给型适中、需求型稍显不足。未来在完善政策体系的同时,提升人才政策执行的效果将更加有利于陕西省人才效益向经济效益转化。     

Analysis of sensitivity and specificity: precise recognition of neutrophils during regeneration of contused skeletal muscle in rats

In this report, we applied the TissueFAXS 200 digital pathological analysis system to rapidly and accurately identify neutrophils during regeneration of contused skeletal muscle, and to provide information for follow-up studies on neutrophils to estimate wound age. Rat injury model was established, and skeletal muscle samples were obtained from the control group and contusion groups at 1, 1.5, 2, 3, 4, and 6 h, as well as at 1, 3, 5, and 15 d post-injury (n = 5 per group). The expression of nuclei and neutrophils was detected by hematoxylin and eosin (HE) staining and immunohistochemical (IHC) staining. A total of 20 injury site areas of 0.25 mm² (0.5 mm × 0.5 mm) were then randomly selected at all time points. A TissueFAXS 200 digital pathological analysis system was used to identify the positive and negative numbers. Knowledge of five professional medical workers were considered the gold standard to measure the false positive rate (FPR), false negative rate (FNR), sensitivity, specificity, and area under the curve (AUC) of receiver operating characteristic (ROC) curves. As a result, with a staining area of neutrophils from 8 µm² to 15 µm², the FPR was 4.28%–12.14%, the FNR was 12.42%–64.08%, the sensitivity was 35.92%–87.58%, the specificity was 87.86%–95.72%, the Youden index was 0.316–0.754, the accuracy was 82.80%–88.30%, and the AUC was 0.771–0.826. The AUC was largest when the cut-off value of the staining area was 12 µm². Our results show that this software-based method is more accurate than the human eye in evaluating neutrophil infiltration. Based on the sensitivity and specificity, neutrophils can be accurately identified during regeneration of contused skeletal muscle. The TissueFAXS 200 digital pathological analysis system can also be used to optimize conditions for different cell types under various injury conditions to determine the optimal cut-off value of the staining area and provide optimal conditions for further study. Furthermore, it will provide evidence for forensic pathology cases.     

Fingerprint analysis for the determination of hand origin (right/left) using the axis slant in whorl patterns

Fingerprints are frequently encountered during both civil and criminal investigations. Fingerprints possess numerous characteristics that assist with personal identification. Determining the hand of origin (right or left) for an individual fingerprint would help reduce investigation time and potentially eliminate certain suspects. In this study, we collected a total of 2 900 single digit fingerprints from 290 individuals, and the whorl axis slant was examined in the 743 whorl pattern fingerprints (385 from the right hand and 358 from the left hand). A slant towards the right side was present in 81.82% of samples from the right hand, while a slant towards the left side was observed in 80.73% of samples from the left hand. After applying a chi-square test to the dataset, the results were found to be statistically significant for the determination of hand origin. Our results suggest that the whorl axis slant in a fingerprint is indicative of hand origin (right or left).

Key points

• Single digit fingerprints with whorl pattern were analyzed.
• Whorl “axis slant” was used to determine the hand origin.
• Right axis slant would indicate the right hand of the print.
• Left axis slant would indicate the left hand of the print.

     

委托理财协议中的保底条款效力之追问

保底条款是委托理财协议中最重要的条款,它不仅决定了这种投资方式的存在与否,同时亦是委托理财失败诉争时当事双方相持不下的根本原因。对于该条款的效力认定,目前的法律与司法实践并没有提供能真正能起到指导与评价作用的答案。因此,从合同的私法性、社会法性及保底条款与其它条款的勾连角度来追问保底条款的效力问题是合理与适法判决的关键所在。
