Marijuana use and repeated attempted suicide among senior high school students in Ghana:Evidence from the WHO Global School-Based Student Health Survey,2012

Background The association between substance use including marijuana use and attempted suicide has been well documented.However,little is known about marijuana use and its association with attempted suicide repetition among young people in low-income and middle-income contexts.Aims This analysis was conducted to assess the factors associated with marijuana use and ascertain marijuana use as a determinant of repeated attempted suicide among senior high school(SHS)students in Ghana.Methods Data from the 2012 Global School-Based Student Health Survey in Ghana was used for this study.Modified Poisson,Logistic and Probit models weighted with Mahalanobis distance matching within propensity calliper were employed separately to determine the hypothetical association between marijuana use and repeated attempted suicide.All analysis was performed using Stata 16 and p<0.05 was deemed statistically significant.Results The prevalence estimates of marijuana use and repeated attempted suicide among SHS students in Ghana were 3.4%(95%Cl:2.3 to 5.1)and 11.5%(95%Cl:9.1 to 14.4),respectively.The prevalence of marijuana use was significantly associated with school grade,smoking exposure,parent smoker,alcohol intake and truancy.Marijuana use was positively associated with repeated attempted suicide among SHS in Ghana correlation=0.23,p<0.001.Repeated attempted suicide among students who use marijuana was approximately threefold and fivefold significant compared with nonmarijuana use students,based on the Poisson(adjusted prevalence ratio:3.02;95%Cl:1.67 to 5.43,p<0.001)and Logistic(adjusted OR:5.06;95%Cl:3.19 to 11.64,p<0.001)estimates respectively.Also,the Probit model showed that marijuana use significantly increased the log count of repeated attempted suicide by 95%(ap:0.95;95%CI:0.49 to 1.41,p<0.001).Conclusion Marijuana use does not only influence the onset of suicidal attempts but also repeated attempted suicide among SHS students in Ghana.Special attention is required for suicide attempters with a history of repeated attempts and current marijuana use among SHS students in Ghana.Early identification of the potential risk and protective factors is recommended to inform school-based interventions.National level structured school-based substance abuse interventions and health promotion programmes would be useful.

Self-Genital Mutilation and Attempted Suicide by Cut Throat in the Same Patient at Presentation: A Rare Event

A Survey of Crime Scene Investigation Image Retrieval Using Deep Learning

Crime scene investigation(CSI)image is key evidence carrier during criminal investiga-tion,in which CSI image retrieval can assist the public police to obtain criminal clues.Moreover,with the rapid development of deep learning,data-driven paradigm has become the mainstreammethod of CSI image feature extraction and representation,and in this process,datasets provideeffective support for CSI retrieval performance.However,there is a lack of systematic research onCSI image retrieval methods and datasets.Therefore,we present an overview of the existing worksabout one-class and multi-class CSI image retrieval based on deep learning.According to theresearch,based on their technical functionalities and implementation methods,CSI image retrievalis roughly classified into five categories:feature representation,metric learning,generative adversar-ial networks,autoencoder networks and attention networks.Furthermore,We analyzed the remain-ing challenges and discussed future work directions in this field.

The Windy City’s Dark Side: A Statistical Exploration of Crime in the City of Chicago

This paper presents a detailed statistical exploration of crime trends in Chicago from 2001 to 2023, employing data from the Chicago Police Department’s publicly available crime database. The study aims to elucidate the patterns, distribution, and variations in crime across different types and locations, providing a comprehensive picture of the city’s crime landscape through advanced data analytics and visualization techniques. Using exploratory data analysis (EDA), we identified significant insights into crime trends, including the prevalence of theft and battery, the impact of seasonal changes on crime rates, and spatial concentrations of criminal activities. The research leveraged a Power BI dashboard to visually represent crime data, facilitating an intuitive understanding of complex patterns and enabling dynamic interaction with the dataset. Key findings highlight notable disparities in crime occurrences by type, location, and time, offering a granular view of crime hotspots and temporal trends. Additionally, the study examines clearance rates, revealing variations in the resolution of cases across different crime categories. This analysis not only sheds light on the current state of urban safety but also serves as a critical tool for policymakers and law enforcement agencies to develop targeted interventions. The paper concludes with recommendations for enhancing public safety strategies and suggests directions for future research, emphasizing the need for continuous data-driven approaches to effectively address and mitigate urban crime. This study contributes to the broader discourse on urban safety, crime prevention, and the role of data analytics in public policy and community well-being.

通过扫黑除恶的社会治理——以贯彻落实《反有组织犯罪法》为视角

在黑恶势力及其违法犯罪严重影响基层政权稳定的严峻形势下,党和国家决定开展扫黑除恶专项斗争,经过三年的全面、深入、系统推进,成效显著,赢得全面胜利。扫黑除恶是国家专门力量直接介入基层社会治理的重要体现,但单纯通过刑事司法或综合治理均无法达到深入且快速的良好治理效果。在总体国家安全观的指导下《,反有组织犯罪法》以“四个结合”为治理理念,构建惩防并举、标本兼治的有组织犯罪治理体系。其具体体现了司法治理与综合治理并重,且重点突出、有机衔接的共治路径及其立法思路。其中,司法治理强调宽严相济刑事政策的细化落实及关联治理机制的体系性完备,综合治理则突出群众路线下治本且治标的综合预防体系健全。通过不断完善的法治来推动常态化、高质效的有组织犯罪治理,保障扫黑除恶的法律效果、政治效果与社会效果相统一,有利于促进实现国家治理体系和治理能力现代化。

侵犯商业秘密罪评价标准的修正与规范解读

《刑法修正案(十一)》完成了侵犯商业秘密罪由数额犯到情节犯的全面转型,但未跟进更新的司法解释易使得司法实务将情节犯作数额犯化处理,仅关注数额要素对于犯罪评价的影响。侵犯商业秘密罪所保护的是复合法益:一是商业秘密权利人对商业秘密享有的私权利,二是市场竞争秩序,后者又可还原为具体的个人法益——商业秘密权。以此为逻辑起点,侵犯商业秘密罪的评价体系应当坚持区分性、形式与实质相统一、强保护的原则,建构综合评价体系。各要素不可单独作为入罪标准,而应综合考量,建构起以数额要素为主,非数额要素为辅的“情节严重”解释体系。

骗取贷款罪中“重大损失”之理解

虽然《中华人民共和国刑法修正案(十一)》已经修改骗取贷款罪的入罪条件,然而关于重大损失的数额计算、产生时间和体系位置等问题的学理讨论尚不充分。重大损失不应包括放贷利息,其产生于贷款到期之后。将重大损失理解成骗取贷款罪客观处罚条件的观点,不符合立法修改主旨和刑法条文内在逻辑,缺乏刑事政策上的合理性。客观超过要素理论本身存在缺陷,其也不适合描述重大损失在骗取贷款罪中的体系位置。骗取贷款罪中“重大损失”与“特别重大损失”直接影响行为刑事可罚性,属于骗取贷款罪的构成要件要素。

Monitoring and Early Warning of New Cyber-Telecom Crime Platform Based on BERT Migration Learning

The network is a major platform for implementing new cyber-telecom crimes.Therefore,it is important to carry out monitoring and early warning research on new cyber-telecom crime platforms,which will lay the foundation for the establishment of prevention and control systems to protect citizens’property.However,the deep-learning methods applied in the monitoring and early warning of new cyber-telecom crime platforms have some apparent drawbacks.For instance,the methods suffer from data-distribution differences and tremendous manual efforts spent on data labeling.Therefore,a monitoring and early warning method for new cyber-telecom crime platforms based on the BERT migration learning model is proposed.This method first identifies the text data and their tags,and then performs migration training based on a pre-training model.Finally,the method uses the fine-tuned model to predict and classify new cyber-telecom crimes.Experimental analysis on the crime data collected by public security organizations shows that higher classification accuracy can be achieved using the proposed method,compared with the deep-learning method.

Abnormal brain activity in adolescents with Internet addiction who attempt suicide: an assessment using functional magnetic resonance imaging

Internet addiction is associated with an increased risk of suicidal behavior and can lead to brain dysfunction among adolescents.However,whether brain dysfunction occurs in adolescents with Internet addiction who attempt suicide remains unknown.This observational cross-sectional study enrolled 41 young Internet addicts,aged from 15 to 20 years,from the Department of Psychiatry,the First Affiliated Hospital of Chongqing Medical University,China from January to May 2018.The participants included 21 individuals who attempted suicide and 20 individuals with Internet addiction without a suicidal attempt history.Brain images in the resting state were obtained by a 3.0 T magnetic resonance imaging scanner.The results showed that activity in the gyrus frontalis inferior of the right pars triangularis and the right pars opercularis was significantly increased in the suicidal attempt group compared with the non-suicidal attempt group.In the resting state,the prefrontal lobe of adolescents who had attempted suicide because of Internet addiction exhibited functional abnormalities,which may provide a new basis for studying suicide pathogenesis in Internet addicts.The study was authorized by the Ethics Committee of Chongqing Medical University,China(approval No.2017 Scientific Research Ethics(2017-157))on December 11,2017.

Predicting the Type of Crime: Intelligence Gathering and Crime Analysis

Crimes are expected to rise with an increase in population and the rising gap between society’s income levels.Crimes contribute to a significant portion of the socioeconomic loss to any society,not only through its indirect damage to the social fabric and peace but also the more direct negative impacts on the economy,social parameters,and reputation of a nation.Policing and other preventive resources are limited and have to be utilized.The conventional methods are being superseded by more modern approaches of machine learning algorithms capable of making predictions where the relationships between the features and the outcomes are complex.Making it possible for such algorithms to provide indicators of specific areas that may become criminal hot-spots.These predictions can be used by policymakers and police personals alike to make effective and informed strategies that can curtail criminal activities and contribute to the nation’s development.This paper aims to predict factors that most affected crimes in Saudi Arabia by developing a machine learning model to predict an acceptable output value.Our results show that FAMD as features selection methods showed more accuracy on machine learning classifiers than the PCA method.The naïve Bayes classifier performs better than other classifiers on both features selections methods with an accuracy of 97.53%for FAMD,and PCA equals to 97.10%.
