大数据助推国家治理现代化：应用影响与政府对策

党的十九届四中全会指出“建立健全运用互联网、大数据、人工智能等技术手段进行行政管理的制度规则”,凸显了大数据等信息技术手段助推国家治理现代化的重要作用。大数据作为一种具有重要价值的战略资源,能够在国家治理领域中推动政府决策科学化、社会治理精准化和公共服务高效化水平的大幅提升。因此,应从组织领导、政策出台、数据中心建设、人才支持以及安全保障等多个维度加大大数据建设力度,助推国家治理体系和治理能力现代化。     

浅析公安科技信息化建设实践中应处理好的三个关系

公安科技信息化建设是公安机关在信息时代推动科技进步、实施“科技强警”战略，实现公安工作跨越式发展和可持续发展的重要手段。当前公安科技信息化建设面临着不小的压力，公安部门应统筹协调、综合处理形成上下对接融合、左右协同配合以及内外信息共享的关系，以便于在公安工作转型升级阶段，为公安科技信息化建设提供更多动力。     

中国共产党的百年青年观:发展阶段、逻辑演进与基本经验

中国共产党成立100周年来,围绕不同历史时期的中心工作,针对"如何认识青年,培养什么青年,如何培养青年"作了大量论述,逐渐形成了"革命型青年观"、"建设型青年观"、"改革型青年观"以及"复兴型青年观",这四个阶段的青年观共同构成了中国共产党青年观的发展阶段.中国共产党青年观的发展有其内在逻辑,呈现出随着时代变化不断丰富完善、继承与发展马克思主义青年观、与时代中心工作同频共振的特征.中国共产党青年观在百年发展阶段中积累了开展青年工作的基本经验,这些经验对于新时代背景下中国共产党进一步加强和改进青年工作具有重要的现实意义.     

统战宣传工作的问题与对策研究——以江门市为例

开展统一战线宣传工作是统战部的主要职责。目前,统战宣传仍存在思想重视不够、机构不健全、经费不足、效果不明显等问题。江门市素有“中国第一侨乡”的美誉,统战资源丰富,强而有力的统战宣传工作使江门统一战线各领域工作事半功倍,有力地促进了江门统战工作的发展。本课题深入调研江门市统战宣传工作情况,分析现状,找出问题,并结合实际,提出对策建议。     

Rapid and nondestructive analysis of lipstick on different substrates using ATR-FTIR spectroscopy and chemometrics

Lipstick can be an important piece of evidence in crimes like murders, rapes, and suicides. Due to its prevalence, it can be an important corroborative evidence in crime reconstruction. The analysis of such evidence can provide an evidentiary link between the suspect, the victim, object, or the crime scene. We report the use of nondestructive ATR-FTIR spectroscopy combined with chemometrics for the classification of 10 brands of lipsticks with nine samples each. Chemometric method of partial least square-discriminant analysis (PLS-DA) has been employed to interpret the data and classify the samples into their respective classes. The PLS-DA model provides an AUC figure above 0.99 in all brands except one; for which it is slightly less at 0.94. We have also tested the traces of these lipstick samples on different substrates treating them as unknowns in the already trained PLS-DA model. 100% of the samples on nine substrates viz. a cotton, nylon, plastic, dry tissue, denim (blue jeans), wet tissue, nitrile gloves, white paper, and polyester were correctly attributed to their source brand. In conclusion, the results suggest that ATR-FTIR combined with the chemometrics is a rapid, nondestructive, and accurate method for the discrimination and source attribution of lipstick. This study has potential for use in actual forensic casework conditions.     

From book to stage to screen: semiotic transformations of Gothic horror genre conventions

ABSTRACT

This paper adopts a multimodal social semiotic approach for exploring the semiotic changes involved in the transformation of a novel into stage and screen productions. It examines how semiotic resources are deployed in each medium through elements of mise-en-scène, such as speech, music, sound, lighting, props, staging, and cinematographic techniques, and the viewing perspectives that are thus established for audiences. The genre of Gothic horror is selected for this purpose, given how this form of performance has transfixed audiences for centuries and has been adapted for both the stage and the screen. In order to demonstrate how each performance medium has produced its own unique set of foregrounding devices to enthral and captivate audiences, a comparative analysis of excerpts from the novel The Woman in Black by Susan Hill, a videotaped theatrical performance, and the 1989 British television film of the same name is undertaken. The paper discusses the implications of the multimodal semiotic approach for developing a better understanding of the semiotic transformations that horror genre conventions undergo in different media and the viewership positions that are thus re-drawn for audiences. The paper concludes with a view of multimodal recontextualisation processes which form the underlying basis of human sociocultural life.     

Management and safety of a medical mission: occupational hazards of volunteering

Medical aid missions involve travel to conflict or danger zones, posing safety risks in addition to the usual occupational risks arising from daily medical work. The note reports on a volunteer mission, using personal reports, anecdotal experiences, and the formal annual report to undertake an assessment similar to worksite assessments for hazards and control measures. Hazards were found to be prevalent, including physical noise and heat, infectious exposure from patients and local vectors, poor water sanitation, and psychosocial stress from unfamiliar environments and large patient numbers with limited means. Implementable preventative measures include increasing awareness with appropriate protective equipment usage and safety guidelines. Mission planning and management should also involve occupational health input.     

Detection of Diatoms by a Combination of Membrane Filtration and Transparentness,

Diagnosis of drowning remains a difficult issue in current forensic sciences. A large number of diatoms were lost by removing the supernatant after centrifugation in the conventional forensic diatom test. We developed a novel membrane filtration method to enrich diatoms from samples. A new solution using different ratios of acetic acid and eugenol is prepared to make the membrane transparent. These processes allow the diatom‐containing membrane to be visualized and identified easily by light microscopy. The tissues contaminated by water rich in diatoms were detected by the new method for the recovery of diatoms. Eleven drowning cases were analyzed by both the new method and the conventional method to compare the sensitivity of both methods. The recovery of the novel diatom test method was 54.2 ± 23.1%. The positive rate of the novel method has been proven to be superior to the conventional method in the diagnosis of drowning.
