构建与新型社区管理相匹配的警务机制

针对基层派出所防范管理主业还未完全凸显,基础工作信息体系还未完全构筑,群防群治网络还未合理严谨的问题,应通过着力推进社区治安巡访机制,强化情报信息和人口管理意识,以构建群防群治网络,严密基层的阵地控制,整治治安问题突出地区,继而调整管理防范的薄弱部位,实施新型社区警务战略。     

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.

     

行政检查公民的住宅必须使用搜查证

公民的住宅权受到宪法保护,政府是否可以通过行政检查来限制这种宪法权利,这就是本文要讨论的关键问题。行政检查与刑事搜查是不同的。相对于刑事搜查而言,行政检查的形式要件是比较简单的。既然行政检查和刑事搜查可能都会涉及被嫌疑人的住所,既然用检查证和搜查证都可以进入被嫌疑人的住所,那么两者就很容易被模糊界限而出现滥用的情况。如果行政检查不需要搜查证,那么警察是否还会刻意去获得搜查证?因此,降低行政检查的标准,就会出现以行政检查为虚、以刑事搜查为实的严重恶果。尤其当警察兼具行政执法和刑事侦查任务时,这种情况更难以避免。     

略论晚清政府关于来华外国人内地游历的执照制度

晚清时期,国门初开,护照制度开始实行。一般来说,护照是一个政府控制入境外国人的最基本、最有效的行政手段,本文拟对晚清政府关于来华外国人所持游历执照的政策作一概述,包括游历执照的分类、主要内容和实施的成效情况。此种游历执照,亦称"护照",但与现代意义上的"护照"有很大区别,是专门注明前往内地游历的通行证件,也起证明持照人身份的作用。     

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。     

当代美国的死刑制度

美国最高法院在1972年曾经宣布暂停死刑执行,但是在1976年又恢复了死刑的执行,目前美国是唯一仍然保留并适用死刑的所谓西方文明国家。美国联邦系统和38个州的刑法都规定了死刑,可以适用死刑的罪行还比较多,但是罪名相对比较集中;死刑诉讼程序严格且复杂;相对于美国庞大的犯罪数字,尤其是暴力犯罪而言,其死刑判决和实际执行死刑数量仍属较低;美国死刑执行方式呈现为以注射方式为主多种执行方法并存的特点。美国死刑程序复杂但是死刑错判率仍然较高。     

浅论加强我国公务员面试考官队伍建设

面试是公务员考录工作中的一个关键环节,公务员面试考官在面试过程中发挥着特殊的作用。但是,目前我国公务员面试考官队伍在素质、培训、确认以及管理等方面存在着诸多的不足。因此,从严把素质关、加强培训、完善监督以及加强考官库建设等方面来加强公务员面试考官队伍的建设刻不容缓。     

从绩效测评视角看企业战略管理

企业战略管理从狭义上说就是对企业战略的制定、实施、控制和修正进行的管理。要做好企业战略管理,首先要建立好企业绩效测评体系。企业绩效测评体系能给制定战略提供所需要的资料与数据,能对战略的实施过程进行监控,能反映战略管理的结果。绩效测评体系对战略管理来说,有着重要的意义。     

专用性资产对机会主义的限制作用分析

在交易成本经济学的治理概念当中,专用性资产是组织结构选择的重要的依据方式。虽然专用性资本的存在会相应的导致套牢问题,但是,专用性资产投资所具有的所有权、专用性、关系性三个特点,同时也可以对机会主义进行有效的限制。
