论刑事案件中电子证据的收集

在刑事案件中,电子证据的收集应由侦查人员进行;根据案情不同,电子证据可按简单流程和复杂流程进行收集;可采取保全公证、技术鉴定及其他方法确保电子证据的真实性和有效性.对于手机短信可采取拍照、记录的方法固定;对于电子邮件除直接向电子邮件收件人和发件人收集电子邮件证据外,还可以从ISP的邮件服务器调取收集相关邮件信息.     

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.     

机动车盗窃犯罪研究

机动车盗窃犯罪具有严重的社会危害性.针对目前机动车盗窃犯罪成员团伙化、犯罪手段智能化和犯罪过程系统化等特点,公安机关应进一步加强公安基础工作以及信息化建设,建立多层次立体化的打防体系.     

自由贸易的神话和东亚自由贸易区的难题

一、东亚贸易：历史与当代的变化 早在几百年前,亚洲区域内部的贸易和经济交往一直就很频繁。当时的东亚国家为了获得类似胡椒和香料这些“本国所不能生产的物资”,就与东南亚国家保持着密切的贸易和经济交往关系。     

论法之难行之源

法之难行已是中国法律实际生活的显豁病症。二十年来产生数以百千万计的法律、法规和规章 ,但绝大多数难以实行。法之难行的病症不愈 ,法治国家建设和寄托于斯的其他事业 ,都将难能制胜或无以为继。为此需要探清法之难行的根源 ,以明救治之策。难行之根源出在立法、行政、司法、法学研究、历史传统等多方面。救治中国法之难行之症 ,需要察源下药。     

论德国宪法人格权的价值基础——以“人的尊严、人权、基本权”的关联为视角

德国法上人格权问题的讨论主要集中在两部分①：一是在民法中对民法人格权的探讨。具体言之,或是在民法总则部分论及姓名权时对以一般人格权为核心的人格权制度加以探讨②;或是在侵权法部分,将一般人格权放到作为侵权行为核心条款的德国民法典第823条第1款③的“其他权利”项下予以集中阐释④。二是在基本法（宪法）中对具基本权位阶的宪法一般人格权的探讨,     

Hair as a specimen to document tetramethylene disulfotetramine exposure

Tetramethylene disulfotetramine (tetramine) is a rodenticide that has been banned for many years in China. Since 2005, inhabitants of a village in the Henan Province have been suffering from grand mal seizures. To investigate the possibility of tetramine as the cause, we developed a method to determine tetramine in human hair. Sample preparation involved external decontamination, frozen pulverization, and ultrasonication in 2 mL ethyl acetate in the presence of cocaine-d3 as an internal standard. The method exhibited good linearity; calibration curve was linear over a range of 0.1-20 ng/mg hair. The limit of detection for the assay was 0.05 ng/mg hair. Except for one subject (No. 4), all head and pubic hair samples were positive for tetramine. The concentrations of tetramine in pubic hair were significantly higher than those in the same subjects' head hair samples. Because of a long retention in body, segmental head hair analysis cannot provide an accurate exposure history of tetramine in the body.     

酌定不起诉的价值辩证与制度改良

酌定不起诉作为现代公诉制度的重要组成部分,在价值层面契合诉讼的经济学原理,符合宽严相济刑事政策在刑事处遇上区别对待、繁简分流的要求,也顺应了构建和谐型司法的时代趋势。酌定不起诉制度的法律规定及实施现状与其价值纬度的合理性不相匹配,应进行必要的制度改良,以更好的舒放其分流潜能,彰显刑事法治的谦抑、轻缓趋向。     

信息经济学视角下的商标制度

为克服信息不对称对交易的负面影响,人们采取了信息、信誉与法律三种应对机制。无论何种机制,其作用的充分发挥都有赖于法律制度的有效保障。在信息经济学语境下,商标的功能就在于标示和区分商品出处,在降低信息成本的同时,激励企业保证商品质量,但激励不等于义务,企业并不因为使用商标而承担额外的品质保证义务。而商标法则通过规定商标确权条件、制止混淆和淡化,确保市场上商标的相互区分,为信息与信誉机制的建立和运行提供法律保障。尽管如此,离开相关法律的协同作用,商标法也难以有效运行。这就决定了只有合理划分商标法与相关法律的调整对象与适用边界,才能完善我国商标法乃至整个市场法制。
