Inhalant abuse detection and evaluation in young Tunisians

Occupational exposure biological monitoring techniques were applied for the diagnosis of inhalation abuse and for the evaluation of the levels of exposure to benzene, toluene, ethylbenzene, xylenes, and n-hexane, in 44 Tunisian adolescents and children suspected for volatile substance addiction. Urinary trans,trans-muconic acid, hippuric acid (HA), mandelic acid, and methylhippuric acids determinations were performed by high performance liquid chromatography with a photodiode array detector, and urinary o-cresol (o-Cr) and 2,5-hexanedione (HD) were extracted simultaneously and measured using gas chromatography with a flame ionization detector. Given the high linearity ranges, HD and o-Cr occupational exposure monitoring techniques could be applied without modification. However, urinary sample dilution was necessary before HA analysis. Concentrations were compared with the maxima of normal values (MNVs) in the general population and to the biological exposure indices (BEIs) used in occupational toxicology. Values as high as 6610-fold the MNV and 68 times the BEI were registered. The subjects showed high exposure to toluene and hexane. Measured metabolites HA and/or o-Cr and HD enabled the easy detection and evaluation of exposure levels. The problem of inhalant abuse should be given more attention and treated through an effective prevention strategy.     

Joint sector reviews—M&E experiments in an era of changing aid modalities: Experiences from JSRs in the education sectors of Burkina Faso,Mali and Niger

Aid policy and practice have been thoroughly shaken up over the past few years. One of the reform areas relates to monitoring and evaluation (M&E). In short, aid recipients are asked to elaborate result‐oriented frameworks while donors are expected to harmonise and align their policies and frameworks. This article examines the extent to which joint sector reviews (JSRs) could take the M&E reform agenda forward. JSRs are M&E exercises at the sector level which have the potential to satisfy the M&E needs of various stakeholders while, at the same time, also contributing to the M&E reform agenda. They are increasingly utilised on the ground, yet, so far, there do not exist any systematic stocktakings and/or analyses of them. Our own analysis of a sample of JSRs from the education sectors of Burkina Faso, Mali and Niger indicate that JSRs score highly on harmonisation, coordination, leadership and broad‐based participation, but poorly on alignment. They generally prioritise accountability over learning needs and largely neglect accountability and learning at the level of the sector institutional apparatus. In this article, findings from the field are contrasted with insights from evaluation theory and practice so as to provide suggestions for on the ground JSR improvements.

对经济安全与经济风险的思考

现实生活中形成了已经或可能对我国经济安全构成威胁的因素主要有 :耕地大量减少、资源浪费严重、环境污染、生态恶化 ,国民经济发展的基础面临严峻考验 ;金融领域的非安全因素日益增加 ;一些产业和一批企业的国际竞争能力严重削弱 ;外贸依存度和资本依存度相对较高 ,出口商品层次较低 ,出口市场过于集中 ;国有企业困难重重。与经济安全问题相联应该备受关注的是经济风险问题。从中长期看 ,我国主要存在潜在的金融风险、产业风险、技术风险、人口风险和决策风险。对我国经济安全与经济风险问题 ,应从国情出发 ,加强研究与监测 ;同时吸收国外的经验和教训 ,尽快制定出有中国特色的经济安全战略 ,建立、健全监测系统和风险防范机制     

视频监控系统在街面犯罪侦查中的应用

近年来,街面犯罪呈现出许多新特点,案件总量不断攀升,如何及时有效地侦破街面犯罪案件,已成为公安机关面临的一项重大课题。合理安装、维护、使用视频监控系统,并将其与其他常规措施、手段相结合,视频监控将在街面犯罪侦查中发挥不可替代的作用。从国内外实践状况和发展趋势看,视频监控系统在街面犯罪侦查实践中的应用成效显著。     

对生活噪声扰人行为实施警察行政管理与处罚的探讨

《治安管理处罚法》第58条对噪声扰人行为的处罚规定具有立法上的进步性,但欠缺执法申的易操作性。作为治安警察首先需要明确可以依据的关于社会生活噪声污染防治的法律规定包括哪些。相关法律条款规定不够完善与细致,干扰他人正常生活认定的主观性,收集生活噪声证据的技术欠缺,这些因素极易导致警察接手此类案件时难以实施处罚,从而影响执法主动性。对立法的修正,监测技术的配备,以及非诉讼的民事调解有助于社会生活中不和谐噪声的消除。     

视频安防监控系统的法律规制原则研究

视频安防监控系统正得到广泛的运用,同时其使用对公民权利也产生了影响。通过对国内外立法、判例中就视频安防监控系统的使用对公民权利的规定的分析,提出视频安防监控系统法律规制的基本原则即公共利益本位原则、职权法定原则、行政正当原则,为当前的立法和执法实践提供参考。     

Android forensics: Automated data collection and reporting from a mobile device

In this research, a prototype enterprise monitoring system for Android smartphones was developed to continuously collect many data sets of interest to incident responders, security auditors, proactive security monitors, and forensic investigators. Many of the data sets covered were not found in other available enterprise monitoring tools. The prototype system neither requires root privileges nor the exploiting of the Android architecture for proper operation, thereby increasing interoperability among Android devices and avoiding a spyware classification for the system. An anti-forensics analysis on the system was performed to identify and further strengthen areas vulnerable to tampering. The contributions of this research include the release of the first open-source Android enterprise monitoring solution of its kind, a comprehensive guide of data sets available for collection without elevated privileges, and the introduction of a novel design strategy implementing various Android application components useful for monitoring on the Android platform.     

Recidivism among drug offenders: A survival analysis of the effects of offender characteristics,type of offense,and two types of intervention

The determinants of recidivism are increasingly becoming the focus of public concern. This study explores the relative effect of type of intervention, offender characteristics, and type of incident offense on time to a petition to revoke probation and time to a probation revocation. Our analysis of intervention effects includes both parametric and nonparametric estimation procedures. Estimating five distributional forms of survival and a proportional hazard model for each measure of recidivism, the analysis indicates no difference in the effect of a program of drug monitoring and treatment, compared to drug monitoring only, for either of the two measures of recidivism. In addition, findings indicate that younger offenders and African American offenders have a shorter time to a petition to revoke probation. We also found a reduced time to failure for a probation revocation for African American offenders and offenders with a prior arrest record. Our findings offer empirical support for a reconsideration of the type of intervention effective in deterring offenders while on probation.     

关于完善我国警务督察程序理念的法哲学思考

在一个法治社会,执法者只有遵循公正的程序执法,才能向公众昭示其行为是具有合法性和权威性的。所以,警务督察系统必须在遵循行政执法公开、参与、便民原则的基础上,从增强程序观念、加强对违反程序规定的监督和追究等方面来培育警务督察人员的执法程序化观念,从而使我国警务督察真正体现法治特性。
