论健全完善党的全面领导的基本规则

围绕坚持加强党的全面领导,党的十九届四中全会决定进一步明确了需要坚持和完善的六个方面的党的领导制度,并把制度完善作为坚持和完善中国特色社会主义制度、推进国家治理体系和治理能力现代化的重要标志。但是,在党的领导制度体系构建中,基本规则的缺失是一个明显不足。对此,要正确认识健全完善党的全面领导基本规则的必要性和紧迫性,明确健全完善新时代党的全面领导基本规则的主要思路,着重围绕信息公开规则、调查研究规则、党委(常委)会议事规则、决策规则和责任规则进行新时代党的全面领导基本规则的构建,使规则作为配套党内法规在党的领导中发挥应有作用。     

2019年国际安全形势：和平局面保持、乱象危机频发

2019年,世界多地动乱频发,特别是拉美地区,发生在一国之内的政治和社会动荡向多国蔓延,并呈持续扩散之势。西亚北非、欧洲、南亚等地区的动乱此起彼伏;传统安全问题进一步上升。除俄罗斯外,各主要国家军费开支再创新高,人工智能军备竞赛初露端倪,美国退出《中导条约》正引发严重后果,太空战也被提上大国军事战略日程,海湾地区冲突和战乱不断;特朗普政府继续坚持“美国优先”,大力推行单边主义和保护主义等霸凌政策,与传统盟友关系裂痕加深,与俄罗斯在中东地区的博弈更趋复杂,与中国的战略竞争不断加剧,大国安全合作不进反退。在上述背景下,全球动荡源和风险点明显增多,中国周边安全环境趋稳向好,但潜在热点和不确定因素增多。同时,当今世界和平、发展、合作的时代潮流未变,维护全球安全治理体系基石的积极力量在不断积聚,这将对国际安全秩序的重组、重塑产生积极影响。     

Research on the local regional similarity of automatic fingerprint identification system fingerprints based on close non-matches in a ten million people database—Taking the central region of whorl as an example

The local regional similarity of fingerprints has always been a hot issue in the field of fingerprint research. With the increasing size of ten-print databases, the appearance of close non-matches (CNMs) in automatic fingerprint identification system (AFIS) candidate lists has attracted increasing attention from forensic science departments worldwide. In this study, three categories (high-, medium-, and low-level) of standards for CNMs were established and 60 whorl samples were marked with different numbers of minutiae to explore the occurrence and influencing factors of CNMs in AFIS candidate lists based on a ten million people database. The results showed that all prints could be found with their corresponding CNMs. The average occurrence rate of CNMs for every query was 52.7% in the top 100 lists, and the most similar CNM was exactly the same in the local area of 12 coincidence points. CNMs appeared more in the middle and lower parts of the central region of the whorl. Moreover, shorter C2C distances and the same finger number and hand led to more CNMs being inspected. CNMs with higher similarity required a more extensive regional area and smaller minutiae density. We concluded that CNMs have a high occurrence rate in large-scale databases and many factors are closely related to them. Fingerprint examiners and researchers need to strengthen their understanding of CNMs to avoid the occurrence of misidentification like the Madrid bombings.

Challenging arbitral awards: A comparative study of Chinese law, british law and UNCITRAL model law

Support and supervision of a court ensure the integrity of the arbitral process and protect the public interest. However, to prevent the confidence of the arbitral system from being damaged, the judicial control should not be too strict. The support and supervision of a court can be seen in many aspects, among which is to challenge an award. Under the Chinese arbitration law, an award made by a foreign arbitration agency is regarded as a foreign award, challenge of which involves resisting recognition and enforcement in accordance with the relevant provisions of the international treaties concluded or acceded to by the People’s Republic of China or on the principle of reciprocity. Accordingly, an award made by a Chinese arbitration agency is regarded as a domestic award, challenge of which includes setting aside and resisting enforcement. As to the grounds and procedures for challenging a domestic award, including foreign-related awards and non-foreign-related awards, some Chinese provisions are either obscure or contradictory. There may be room for the Chinese system to be modernized. The Model Law and the English Arbitration Act of 1996 may be used for its reference.     

公司治理的现实选择

公司治理无论从理论上还是实践上都已成为最重要的管理课题之一。主流的研究目标是通过科学合理的公司治理结构保护小股东的权益,而实践中并非只有大股东侵害小股东,中小股东通过内部人控制同样可以严重侵害大股东的利益。通过对治理结构的国际化比较,公司治理的现实选择应为:没有固定的模式;大股东有利益才能最终保护小股东;非经济因素对公司治理具有制约和促进的作用。

A comparative study on the concentrations of 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid (THCCOOH) in head and pubic hair

In this study, the concentrations of 11-nor-Δ(9)-tetrahydrocannabinol-9-carboxylic acid (THCCOOH) in pubic, axillary and beard hair were measured and the correlation between the concentrations of THCCOOH in head and pubic hair from same cannabis users were evaluated. The papers on body hair analysis for THCCOOH were rarely found although police officers submit body hair as a complimentary specimen to forensic laboratories in case cannabis users had no hair. Head, pubic, axillary, and beard hair were collected. All hair samples were cut into 0.5mm segments and decontaminated with methanol, digested with 1 mL of 1M NaOH at 85 °C for 30 min and extracted in 2 mL of n-hexane:ethyl acetate (9:1) two times after adding 1 mL of 0.1N sodium acetate buffer (pH = 4.5) and 200 μL of acetic acid followed by derivatization with 50 μL of PFPA and 25 μL of PFPOH for 30 min at 70 °C. The extracts were analyzed using gas chromatography tandem mass spectrometry operating in negative chemical ionization mode (GC/MS/MS-NCI). We determined the concentrations of THCCOOH in both pubic and head hair. The concentrations of THCCOOH in pubic hair were higher than those in head hair. We also evaluated the concentrations of THCCOOH in body hair (pubic, axillary and beard hair) and head hair according to the positive/negative urine test results. There was no statistically significant difference in the concentrations of THCCOOH in head and body hair according to urine results.     

Forged seal detection based on the seal overlay metric

This paper describes a method for verifying the authenticity of a seal impression imprinted on a document based on the seal overlay metric, which refers to the ratio of an effective seal impression pattern and the noise in the neighborhood of the reference impression region. A reference seal pattern is obtained by taking the average of a number of high-quality impressions of a genuine seal. A target seal impression to be examined, often on paper with some background texts and lines, is segmented out from the background by an adaptive threshold applied to the histogram of color components. The segmented target seal impression is then spatially aligned with the reference by maximizing the count of matching pixels. Then the seal overlay metric is computed for the reference and the target. If the overlay metric of a target seal is below a predetermined limit for the similarity to the genuine, then the target is classified as a forged seal. To further reduce the misclassification rate, the seal overlay metric is adjusted by the filling rate, which reflects the quality of inked pattern of the target seal. Experiment results demonstrate that the proposed method can detect elaborate seal impressions created by advanced forgery techniques such as lithography and computer-aided manufacturing.     

Degradation in soil of precursors and by-products associated with the illicit manufacture of methylamphetamine: implications for clandestine drug laboratory investigation

Key precursors and by-products in the Leuckardt, Nagai and dissolving metal reductive syntheses of methylamphetamine undergo degradation in soil as a result of biotic and abiotic processes. Furthermore, methylamphetamine is a product of the degradation of 1-(1',4'-cyclohexadienyl)-2-methylaminopropane and N-formylmethylamphetamine. These findings have implications for the forensic assessment of buried residues recovered from clandestine laboratory sites because markers used to infer the synthetic methods used might be absent as a result of degradation and because methylamphetamine might be present in residues as a result of degradation rather than as a direct result of its manufacture in the laboratory.
