河南省经济结构现状及优化升级问题研究

近年来,随着国家经济结构调整的不断深入,河南省迎来了全面发展的新时期。河南省经济结构在不断优化的同时,结构性矛盾仍然比较突出,主要表现在内需动力不足,产业结构层次低,支柱、重点行业不明显,城乡居民收入差距较大,三大产业就业结构不合理等方面。针对以上问题,结合河南省经济结构的实际状况,其经济结构战略性调整应发挥政府职能,合理分配资源;深入实施乡村振兴战略;加快新型城镇化进程;推进产业结构优化升级。只有这样,河南省经济结构优化升级问题才能真正得到根本改善。     

丝绸之路经济带建设中金融支持与保障研究

丝绸之路经济带建设坚持“政策沟通、道路联通、贸易畅通、货币流通、民心相通”的五通原则中,货币流通是基础和先导。开展金融合作不仅是经贸合作的基础,而且也是顺应金融市场全球化和金融监管国际化的内在要求。从微观、中观和宏观三个角度阐述金融在丝绸之路经济带建设中的支持作用,分析丝绸之路经济带建设中的金融支持面临的各种挑战,建议从开发性金融为先导引领区域金融支持;拓展人民币结算和扩大互换规模,推进区域性金融支持;推进国内金融机构的国际化水平;发展互联网金融,创新金融支持模式;建立丝路区域性国际金融中心;加强国际金融治理以及金融监管协调合作。     

信贷歧视、产能过剩与中国经济波动：基于金融冲击的视角

通过建立民营企业与国有企业间存在信贷歧视的动态随机一般均衡模型，考察金融冲击的宏观经济效应。研究结果表明，尽管积极性金融冲击有助于实现宏观经济稳定，但信贷歧视削弱了积极性金融冲击的宏观经济效应，忽略信贷歧视评价金融冲击的影响将导致结论偏误。在此基础上，进一步考虑了由信贷歧视引致的产能过剩问题的影响。结果显示，产能过剩进一步削弱了积极性金融冲击的实际效应，并扩大了其对通胀等名义变量的影响。而二阶矩分析的结果则表明，信贷歧视以及由信贷歧视引致的产能过剩加剧了宏观经济波动，降低了实际变量的持续性，同时提高了通胀惯性的影响。因此，为有效发挥积极性金融冲击的作用，稳定宏观经济，需要采用相关政策有效缓解信贷歧视以及产能过剩问题。     

庭审阶段补充侦查制度合理性省思——以审判中心主义为背景

庭审阶段的补充侦查制度是职权主义诉讼结构和"侦查中心主义"的产物,其理念是追求"实体真实"。该制度不符合当前以审判为中心的刑事诉讼制度改革的精神,有违控辩平衡的诉讼原则,也不利于保障被告人的人权,导致司法资源浪费和诉讼效率降低,且有侦查权僭越审判权之嫌。针对上述弊端,结合检察机关正在实行的以"案-件比"为中心的考核机制,宜尽快废除庭审阶段的补充侦查制度。作为补偿,应当赋予控辩双方平等的证据申请权,改由人民法院进行庭外调查,庭外调查的重点应是有利于被告人的证据。对于庭审阶段翻证的证人,不宜由侦查(调查)机关单方面询问核实,而应当通知其出庭作证。     

中美特殊经贸关系与“契约”之路径

晚近,中美作为非同质的两个世界大国,新兴的一方与守成的另一方发生了巨大的权力变迁,相应地,双方在国际经贸领域的收益分配也出现了反转的态势,同时中美形成的激烈经济与战略竞争使得双方经贸关系"政治化"更加明显。缘此,中美之间的既有经贸关系正面临着前所未有的变动压力,或已难以完全固守普适于各国的统一"规则",客观上需要引入一种可适时而变的专门"契约"加以修补,借以寻求双方之间收益分配的再平衡。     

当前命案发案特点与侦控对策

自2004年公安部开始开展"命案必破"专项行动以来,全国各级公安机关不断结合自身实际,创新侦查工作方法,完善侦破机制,效果明显.深入总结十年来命案侦办工作经验,从案件发生、侦查过程、作案人员以及发案地域等因素对当前命案基本情况进行实证分析,同时归纳总结近年来各地先进经验,对于有效预防以及快速侦办命案具有较强的现实意义,对于提高整体侦查效能也有所助益.     

We are meeting on Microsoft Teams: Forensic analysis in Windows,Android, and iOS operating systems

Microsoft released a new communication platform, Microsoft Teams, in 2017. Due in part to COVID-19, the popularity of communication platforms, like Microsoft Teams, increased exponentially. Given its user base and increased popularity, it seems likely that digital forensic investigators will encounter cases where Microsoft Teams is a relevant component. However, because Microsoft Teams is a relatively new application, there is limited forensic research on the application particularly focusing on mobile operating systems. To address this gap, an analysis of data stored at rest by Microsoft Teams was conducted on the Windows 10 operating system as well as on Android and Apple iOS mobile operating systems. Basic functionalities, such as messaging, sharing files, participating in video conferences, and other functionalities that Teams provides, were performed in an isolated testing environment. Cellebrite UFED Physical Analyzer and Magnet AXIOM Examine tools were used to analyze the mobile devices and the Windows device, respectively. Manual or non-automated investigation recovered, at least partially, the majority of artifacts across all three operating systems. In this study, a total of 77.6% of the populated artifacts were partially or fully recovered in the manual investigation. On the other hand, forensic tools used did not automatically recover many of the artifacts found with the manual investigation. Only 13.8% of artifacts were partially or fully recovered by the forensic tools across all three devices. These discovered artifacts and the results of the investigations are presented in order to aid digital forensic investigations.     

Medical examiner response to the drug overdose epidemic in King County Washington: “Real-time” surveillance,data science,and applied forensic epidemiology

As the overdose epidemic overwhelmed medicolegal death investigation offices and toxicology laboratories, the King County Medical Examiner's Office responded with “real-time” fatal overdose surveillance to expedite death certification and information dissemination through assembling a team including a dedicated medicolegal death investigator, an information coordinator, and student interns. In-house testing of blood, urine, and drug evidence from scenes was performed using equipment and supplies purchased for surveillance. Collaboration with state laboratories allowed validation. Applied forensic epidemiology accelerated data dissemination. From 2010 to 2022, the epidemic claimed 5815 lives in King County; the last 4 years accounted for 47% of those deaths. After initiating the surveillance project, in-house testing was performed on blood from 2836 decedents, urine from 2807, and 4238 drug evidence items from 1775 death scenes. Time to complete death certificates decreased from weeks to months to hours to days. Overdose-specific information was distributed weekly to a network of law enforcement and public health agencies. As the surveillance project tracked the epidemic, fentanyl and methamphetamine became dominant and were associated with other indicators of social deterioration. In 2022, fentanyl was involved in 68% of 1021 overdose deaths. Homeless deaths increased sixfold; in 2022, 67% of 311 homeless deaths were due to overdose; fentanyl was involved in 49% and methamphetamine in 44%. Homicides increased 250%; in 2021, methamphetamine was positive in 35% of 149 homicides. The results are relevant to the value of rapid surveillance, its impact on standard operations, selection of cases requiring autopsy, and collaboration with other agencies in overdose prevention.     

Impinging blood droplets on different wettable surfaces: Impact phenomena,contact line motion,post-impact oscillation and dried stains

Understanding the underlying hydrodynamics of impinging blood droplets and finding out the physical parameters determining the bloodstain characteristics are of great importance in blood related forensic investigations. In this work, the impact of non-Newtonian blood droplets on solid surfaces ranging from lyophilic to superlyophobic was systematically investigated and compared to that of Newtonian droplets with a similar dynamic shear viscosity. We show that impinging blood droplets behave as low-viscosity Newtonian droplets in the short-time spreading, which is dominated by capillary and inertial forces, but their non-Newtonian viscoelasticity would notably affect the droplet retraction and post-impact oscillation occurring in large timescales. Whereas the strong liquid–solid adhesion and the non-Newtonian elongational viscosity hinder droplet recoiling and thus alter the impact phenomena on lyophobic and superlyophobic surfaces, the shear and elongational viscosities are coupled to result in higher damping coefficients of oscillating blood droplets after deposition, in comparison to that of impinging Newtonian droplets. The size of the dried bloodstain was found to be different from both the maximum spreading radius of the droplet that can reach during impact and the final radius of the deposited droplet after oscillation, and their correlations are highly dependent on the impact velocity and surface wettability. Moreover, the morphologic characteristics of the bloodstains would also be changed by varying either the impact velocity or the surface wettability. We envision that these findings can not only find applications in the bloodstain pattern analysis, but also provide useful information for medical diagnosis based on blood droplet test.     

The Bifurcation of Politics: Two Englands

A dynamic of global economic development means that many countries are experiencing uneven development and their citizens are increasingly split between those who can access high‐skill jobs and those who cannot. As a result some citizens are living in cosmopolitan areas of growth and others in backwater areas of decline. There are emerging out of these processes two versions of England. In cosmopolitan areas we find an England that is global in outlook, liberal and more plural in its sense of identity. In provincial backwaters we find an England that is inward‐looking, relatively illiberal, negative about the EU and immigration, nostalgic and more English in its identity. This bifurcation of England is already having political effects, reflected in the outcome of the 2015 general election. It will further reconfigure politics over the next two decades, creating diverse political citizens and a complex array of challenges and dilemmas for governments, political parties, campaigners and political organisers.
