省直管县改革背景下市县横向分治与合作机制之构建

省直管县改革是为适应经济社会快速发展而进行的行政层级调整,对于破除市管县体制藩篱、激活和增强县域经济发展活力、提高行政效率具有重大意义。实践中,市县科层结构"交错纠缠"、省级政府管理幅度偏大、市县资源依赖关系受到冲击等问题一定程度上影响了省直管县改革的推进,导致改革的政策红利未能充分释放。应从增加省直管县试点数量、推动市县科层结构扁平化、维护市县共生性资源依赖关系、引导市县从资源竞争走向差异化合作等方面着手构建并完善市县横向分治与合作机制,以推动省直管县改革取得更大成效。     

什么样的“闹大”成功了?--基于40个案例的定性比较分析

社会中层出不穷的"闹大"是公共治理状况的一面"镜子",也是转型时期政策议程建构的重要路径。本文采用清晰集定性比较分析(csQCA),对2003-2019年发生的40个"闹大"案例进行比较研究。研究结果表明,上级(层)政府支持是"闹大"成功的必要条件。推动"闹大"成功的充分条件组合共有八种,可具体归纳为制度框架使用模式、集体施压模式、专家引导模式和暴力强推模式等四种解释模型。公民"闹大"成功是多个条件组合的结果,在核心条件发挥基础作用的前提下,适当的辅助条件更容易触发政策议程,推动问题解决。文章为公民"闹大"的行动逻辑提供了新的因果解释机制,也为理解形形色色的"闹大"现象提供了新的理论工具。     

A mixed DNA profile controversy revisited

Semaan et al. (J Forensic Res, 2020, 11, 453) discuss a mock case “where eight different individuals [P₁ through P₈] could not be excluded in a mixed DNA analysis. Even though … expert DNA mixture analysis software was used.” Two of these are the true donors. The LRs reported are incorrect due to the incorrect entry of propositions into LRmix Studio. This forced the software to account for most of the alleles as drop-in, resulting in LRs 60–70 orders of magnitude larger than expected. P₁, P₂, P₄, P₅, and P₈ can be manually excluded using peak heights. This has relevance when using LRmix which does not use peak heights. We extend the work using the same two reference genotypes who were the true contributors as Semaan et al. (J Forensic Res, 2020, 11, 453). We simulate three two-donor mixtures with peak heights using these two genotypes and analyze using STRmix?. For the simulated 1:1 mixture, one of the non-donors’ LRs supported him being a contributor when no conditioning was used. When considered in combination with any other potential donors (i.e., with conditioning), this non-donor was correctly eliminated. For the 3:1 mixture, all results correctly supported that the non-donors were not contributors. The low-template 4:1 mixture LRs with no conditioning showed support for all eight profiles as donors. However, the results from pair-wise conditioning showed that only the two ground truth donors had LRs supporting that they were contributors to the mixture. We recommend the use of peak heights and conditioning profiles, as this allows better sensitivity and specificity even when the persons share many alleles.     

Observer determination of the make,model, and year of questioned vehicles

Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year.     

“一带一路”背景下国际发展经济学学科综述

国际发展研究是反映现实世界变化的窗口之一。最近几年的发展经济学文献对诸如援助的动因、援助有效性等传统议题的研究更为深入,对新议题的探索也逐渐涌现。移民问题、局部地区的战争与恐怖主义活动与援助的相互关系,援助是如何塑造受援国行为及其所产生的效果,是反映援助国政治诉求的现实性研究。除此之外,源自其他学科的新研究方法也丰富了学者们对传统议题研究手段,补充了传统研究方法在诸如内生性等问题上存在的缺陷。     

论人工智能赋值国家治理:方法、视角与维度

赋值是智能政治学的重要研究课题,赋值研究是智能政治学的重要分析方法。人工智能赋值国家治理,从分析视角来看,表现为人工智能科学、人工智能技术、人工智能形态和人工智能体对国家治理的多重赋值和多源性影响作用。从分析维度来讲,表现为人工智能从赋益、赋义、赋能、赋权、赋则和赋责等多维度影响作用或赋值国家治理,甚至推动国家治理从"人工智能+国家治理"的形式赋值质变为"人机智能治理"的实质赋值。选择"赋值"术语工具、赋值理论和赋值分析方法,以分析研究人工智能影响作用国家治理,将有助于探明人工智能赋值国家治理的理论逻辑、历史逻辑和实践逻辑,从而推动智能政治学以及国家智能治理问题的理论研究和学术创新。     

未来十年增长潜力预测与“十四五”时期战略目标、战略重点

“十四五”时期是我国从全面建成小康社会向基本实现社会主义现代化迈进的关键过渡期。基于数量和质量双重维度，采用趋势外推法预测未来经济增长潜力，未来十年中国的潜在经济增长率呈现明显下降态势，而经济增长质量潜力则出现显著上升趋势。“十四五”时期建设社会主义现代化国家的战略目标包括以推动高质量发展为基本导向、以提升国家核心竞争力为集中体现、以增进人民福祉为最终目的、以推进国家治理现代化为重要保障。在此基础上，“十四五”时期的战略重点是更加有力的创新驱动、更加优化的经济结构、更加完善的基础设施体系和更加现代化的发展道路。     

Covid-19 Pandemic,Social Mitigation and Taxation: The Open Veins of Inequality in Latin America

The pandemic of Covid-19 has exposed the veins of inequality in Latin America. With a socioeconomic disaster looming, social emergency policies seemed inevitable. Yet while governments argue over the continuity of such policies and whether the fiscal rules in place should be respected, no sustainable response has come out. This essay problematises whether the pandemic could represent a critical juncture to forge ahead with political narratives that highlight tax exemptions and privileges enjoyed by the rich. We analyse the mitigation measures adopted by Argentina, Brazil, Chile and Uruguay and their repercussions on the debate surrounding progressive tax reforms to fund social schemes.     

DNA Recovery From Tape-Lifting Kits: Methodology and Practice

In the case of suspicious deaths, the technique of 1:1 taping is often used in Belgium. It consists of affixing a large number of adhesive tapes to the body of the victim. It is conventionally aimed at obtaining microtraces (e.g., fibers, hair) and is usually not used for DNA analysis. However, in some cases, DNA analysis of certain areas of interest identified on the 1:1 taping material can offer a last resort solution. The four-step method that is described in this article involves the selection of areas of interest on the body (Step 1), the selection of the corresponding tapes (Step 2), the decontamination of the tapes (Step 3), the selection of areas of interest on the tapes, for DNA sampling (Step 4). The method is illustrated by its successful application in four murder cases. In each case, DNA profiles of good quality could be identified, including profiles of persons different from the victim.
