登记手册一直是海关监管加工贸易的重要工具,但在实物流和资金流的流转过程中会引起经济行为的变化,甚至会引发经济犯罪。为遏止经济犯罪的发生和发展,行政部门必须强化行政监管,公安机关应加强业务培训,提高经侦民警发现和甄别经济犯罪的能力,并且要充分调动社会各界大胆检举揭发经济犯罪的积极性,从而为经济建设保驾护航,维护良好的市场经济秩序。  相似文献

Proficiency testing has the potential to serve several important purposes for crime laboratories and forensic science disciplines. Scholars and other stakeholders, however, have criticized standard proficiency testing procedures since their implementation in laboratories across the United States. Specifically, many experts label current proficiency tests as non-representative of actual casework, at least in part because they are not sufficiently challenging (e.g., [1], [2], [3], [4]. In the current study, we surveyed latent print examiners (n = 322) after they completed a Collaborative Testing Services proficiency test about their perceptions of test items. We also evaluated respondents’ test performance and used a quality metric algorithm (LQMetrics) to obtain objective indicators of print quality on the test. Results were generally consistent with experts’ concerns about proficiency testing. The low observed error rate, examiner perceptions of relative ease, and high objective print quality metrics together suggest that latent print proficiency testing is not especially challenging. Further, examiners indicated that the test items that most closely resembled real-world casework were also the most difficult and contained prints of the lowest quality. Study findings suggest that including prints of lower quality may increase both the difficulty and representativeness of proficiency testing in latent print examination.  相似文献

巨大交通流量在短时间内规律性地高度集中和疏散,已经成为城市内一种日益常见的交通行为现象,典型的有如一些办学规模较大的中小学学校通学交通以及由此衍生的其他交通行为。本文结合湖南省娄底市第一中学等学校所在区域的交通问题,通过实证分析的方法,在对道路基础设施不做大型建设改造的低投入原则下,通过交通组织理论和交通管理手段的合理运用,采用单向交通、错时上下学等简便而且低投入的交通组织与管理措施,对存在交通难题进行了极为有效改善,并从此得到相应启示。  相似文献

运用西方宏观经济理论中关于经济动态效率模型理论,对近十年来台湾地区经济动态效率的变化情况进行了实证考察,研究发现:近十年来台湾地区经济动态有效状态明显且呈现逐渐增强趋势。由于经典的宏观经济增长理论并不能很好解释台湾地区经济动态效率的变化情况,深入分析发现,近十年来台湾地区资本流动是其经济动态效率改善的关键性因素。中国大陆作为台湾对外投资的最主要地区,是台湾地区经济发展的重要依托,在改善台湾地区经济动态效率方面发挥着重要作用。  相似文献

Novel hydrophobic silica based particles have been developed to visualise latent fingerprints. The composition of the particles has been designed to maximise both hydrophobic and ionic interactions between a variety of coloured and fluorescent reporter molecules and the silicate backbone within the particles. The resulting doped particles retain the incorporated dyes with high affinity. In addition, a variety of sub-particles have also been embedded to again produce coloured or magnetisable hydrophobic particles. The particles can be harvested as nanoparticles or microparticles. The former are applied to latent fingerprints as an aqueous suspension and the latter as a dusting agent using brushes or a magnetic wand. Examples of the prints produced using these agents are given. The resulting prints have good definition.  相似文献

Literature on political support broadly offers three micro-level models: socio-economic status, democratic process evaluations, and political performance evaluations explain people's differences in satisfaction with democracy. While tests show that these explanations complement each other, we do not know how. We combine for the first time all three models into one common longitudinal framework by explicitly considering aspects of time. We argue that relatively stable factors, such as socio-economic status, only explain general levels, whereas more time-sensitive factors, such as evaluations, explain differences between citizens at specific points in time. The results of latent growth curve modelling applied to nine-wave panel data support our general hypothesis of a common longitudinal framework. These results also show that economic evaluations play a prominent role as do some (but not all) electoral results. The findings have theoretical and methodological implications, and they offer a new perspective on the meaning of ’satisfaction with democracy’.  相似文献

This essay and review on criminal network analysis provides an introduction to the special issue “Human Capital and Social Capital in Criminal Networks”. It traces the history of the application of network analysis in the study of organized crime since the early 1970s. It argues that while criminal network analysis has brought a new level of methodological rigor to the study of organized crime, a number of limitations have become apparent. These include the problem of missing data and the challenges encountered in adequately capturing latent structures, individual characteristics of network members and socio-ecological conditions.  相似文献
