对足球运动员比赛中攻击与暴力行为的分析研究

现代体育运动竞争激烈,在足球运动中球场上的暴力事件层出不穷,足球运动员在比赛中攻击和暴力行为也频频出现。本文通过对体育竞赛中攻击性行为和暴力行为的概念以及攻击理论的分析研究,归纳了足球运动员在比赛中攻击性行为和暴力行为产生的因素,以及对此现象的控制和预防措施,以期在足球比赛中运动员尽量避免不文明行为的发生,净化赛场风气。     

从全球化视角探讨武术教育的生存与发展

在以“西欧崛起”为标志的现代全球化背景下,古代武术教育体系经西洋“军事和强权文化”淹没而向近现代转型。淹没和转型,既在一定程度促进了武术教育的新生和发展,也在一定程度上导致武术教育个性的失落。在由征服与扩张,向世界、地域、本土相互对应而又相互统一方向发展的当代全球化背景下,应该突破百年来形成的专注共性、忽略个性的习惯,树立以“张扬个性”为核心的观念,通过张扬个性弘扬共性,推动武术教育的科学发展。

加强改制企业人事档案管理的思考

随着我国社会主义市场经济建设的不断发展,国有企业的改制工作逐步深入,许多企业的所有制性质也发生了变化,由原来的国营、集体所有制企业,改制为股份制企业、民营企业等多种形式的经济实体。由于企业的性质及管理模式发生了变化,企业人事档案管理中就出现了一些新的矛盾和问题。研究新情况、解决新问题,不断加强和改进企业的人事档案管理,已成为改制企业人事档案管理部门的一个新课题。一、存在的问题及原因企业改制后,普遍存在人事档案管理意识淡薄、管理疏散、档案归属和流向不明等问题。造成这种状况的原因是多方面的,既有思想认识上的…

The more multidisciplinary the better? – The prevalence and interdisciplinarity of research collaborations in multidisciplinary institutions

Scientific research is increasingly relying on collaborations to address complex real-world problems. Many researchers, policymakers, and administrators consider a multidisciplinary environment an important factor for fostering research collaborations, especially interdisciplinary ones that involve researchers from different disciplines. However, it remains unknown whether a higher level of multidisciplinarity within an academic institution is associated with internal collaborations that are more prevalent and more interdisciplinary. Analyzing 90,000 publications by 2500 faculty members in over 100 academic institutions from three multidisciplinary areas, information, public policy, and neuroscience, we investigated the connection between multidisciplinarity and research collaborations. Based on social network analysis and text mining, our analysis suggests that more multidisciplinary institutions are not necessarily more collaborative, although they do feature collaborations that are more interdisciplinary. Our findings provide implications for academic administrators and policymakers to promote research collaborations and interdisciplinarity in academic institutions.     

Smart responsive organic microlasers with multiple emission states for high-security optical encryption

Modern high-security cryptography and optical communication call for covert bit sequences with high coding capacity and efficient authentication. Stimuli-responsive lasing emissions with easily distinguishable readout are promising in the coding field as a novel cryptographic primitive, while the application is frequently restricted by the limited number of emission states. Here, we report a strategy of achieving multiple competitive lasing signals in responsive organic microspheres where a donor–acceptor pair was introduced. The competitive lasing from the donor and acceptor was reversibly switched by modulating the competition between the radiative rate of the donor and the rate of energy transfer, and the generated multiple lasing signals enabled a quaternary coding for recognizable cryptographic implementation. Data encryption and extraction were demonstrated using a 4 × 4 microlaser array, showing vast prospects in avoiding the disclosure of security information. The results offer a comprehensive understanding of excited-state dynamics in organic composite materials, which may play a major role in high-security optical recording and information encryption.

A CRISPR/Cas12a-empowered surface plasmon resonance platform for rapid and specific diagnosis of the Omicron variant of SARS-CoV-2

The outbreak of the COVID-19 pandemic was partially due to the challenge of identifying asymptomatic and presymptomatic carriers of the virus, and thus highlights a strong motivation for diagnostics with high sensitivity that can be rapidly deployed. On the other hand, several concerning SARS-CoV-2 variants, including Omicron, are required to be identified as soon as the samples are identified as ‘positive’. Unfortunately, a traditional PCR test does not allow their specific identification. Herein, for the first time, we have developed MOPCS (Methodologies of Photonic CRISPR Sensing), which combines an optical sensing technology-surface plasmon resonance (SPR) with the ‘gene scissors’ clustered regularly interspaced short palindromic repeat (CRISPR) technique to achieve both high sensitivity and specificity when it comes to measurement of viral variants. MOPCS is a low-cost, CRISPR/Cas12a-system-empowered SPR gene-detecting platform that can analyze viral RNA, without the need for amplification, within 38 min from sample input to results output, and achieve a limit of detection of 15 fM. MOPCS achieves a highly sensitive analysis of SARS-CoV-2, and mutations appear in variants B.1.617.2 (Delta), B.1.1.529 (Omicron) and BA.1 (a subtype of Omicron). This platform was also used to analyze some recently collected patient samples from a local outbreak in China, identified by the Centers for Disease Control and Prevention. This innovative CRISPR-empowered SPR platform will further contribute to the fast, sensitive and accurate detection of target nucleic acid sequences with single-base mutations.
