Determination of disperse dyes on polyester fibers by UHPLC–Orbitrap MS

The determination of fiber dyes is important in forensic investigations. Although a variety of fiber dyes detection methods have been established, the sensitive and accurate determination of trace fiber dyes remains a challenge due to the possible interferences caused by complex environmental matrix and various fiber additives. Orbitrap mass spectrometry (Orbitrap MS) is a type of high-resolution mass spectrometry with high qualitative accuracy and detection sensitivity which highly meet the identification requirements of fiber dyes in real cases. However, the application of Orbitrap MS in fiber dye analysis is limited. In this regard, this study used polyester fiber, which is the most commonly-found fiber in forensic cases, as a model and established a UHPLC–Orbitrap MS method to analyze disperse dyes on polyester fibers. Using the optimized UHPLC–Orbitrap MS method, nine disperse dyes were accurately identified and well separated, and the limits of detection ranged between 0.1 ng/mL and 5.0 ng/mL. The developed method was applied to analyze actual fiber samples, and dyes from single fibers of 1 mm in length could be accurately detected. The established method is sensitive, accurate, and demonstrates good application prospects.     

制度运行伦理：和谐社会的伦理支撑

制度运行伦理作为制度伦理的一个重要方面,与制度设计伦理是有所不同的。它本身包含着的价值原则和道德基础与和谐社会具有同构性与一致性。作为和谐社会构建的主要组成方面,和谐社会对制度运行伦理的价值诉求体现在三个方面：社会结构层面——合理、政治层面——民主、经济层面——公平正义。     

美国与拉美民粹主义的主要区别与左右分野

民粹主义在美国和拉美地区具有不同的发生和发展史。与在拉美不同,民粹主义在美国起源时间较早,但发生频率较低,持续时间较短,彼此关联性不强,影响程度较弱,激进程度较轻。特朗普式的民粹主义在很大程度上体现了美国民粹主义的“拉美化”倾向。民粹主义在美国和拉美有很明显的左右分野,左翼民粹主义在拉美长期占据主流,右翼民粹主义在美国则是主要形式。在与何种类型的左右翼结合、是否与民族主义结盟、集权程度等多个方面,这两个地区的左右翼民粹主义也存在较大差别。目前,美国和拉美的左右翼民粹主义正在同时崛起。特朗普的民粹主义可谓集美国的左右翼民粹,尤其是极右翼民粹主义之大成。民粹主义说到底是民主政治的民粹化,源于大众民主政治的内生问题。美拉民粹主义的重要差异,主要来自两个地区不同的政治文化传统和选举民主机制,以及民主体制不同性质和程度的政治衰败。美拉民粹主义左右分野的背后,实质上是公民的基本权利保障不彰所致。具体而言,是自由议程与平等议程之间的张力以及由此导致的社会主要矛盾的不同。因此,必须认真对待左右翼民粹主义,加强制度建设,提高国家治理能力,同时还应积极参与全球治理。     

行政事业性国有资产管理问题思考

作为国有资产的一个重要组成部分,行政事业性国有资产是保障国家机关高效运转和各项社会事业快速发展的重要物质基础。但与强化经营性国有资产管理相比,各级政府对行政事业性国有资产的监管却成为整个国有资产管理中相对薄弱的环节。针对行政事业性国有资产管理中存在的主要问题及其成因,需要从制度变迁的角度加强完善并拿出应对之策。     

制度经济学视野下宽严相济的经济犯罪控制对策研究

随着"宽严相济"刑事政策的出台,刑法势必重新选择对经济犯罪的控制对策,以摆脱效益与公正性的困境。根据这种对策所形成的制度安排应当在减少交易成本和保障制度创新方面符合市场经济的基本要求,具体包括两个方面:构建非刑法的经济犯罪控制体系;根据经济违法行为的不同危害性构建相应的刑法控制体系。     

制度伦理教育的合法性审视

制度伦理教育是指致力于使人认可、内化并践行契约伦理的教育.在我国,随着市场经济的发展,罗尔斯正义理论在教育界的影响日益深远等,它已经悄然兴起.合法性判断是对事物是否符合社会、时代发展的一个最基本的判断,所以对制度伦理教育进行合法性判断是非常必要的.道德教育合法性判断的依据包括道德伦理合法性判断的依据和道德教育方式方法合法性判断的依据.前者具体可分为民意、文化传统和超越三重依据;后者具体可分为尊重常识道德、教育者"言行一致"、旨在于使人向善、有效性四重依据.以这些依据作为评判的标准,不难发现制度伦理教育尽管有很多地方值得我们去借鉴,但它并不具有很强的合法性基础,它的兴起不能实现其已有的承诺.     

国际制度竞争、利益分配与国际秩序转型

国际秩序转型的动力、过程和方向是政策界与理论界关注的核心议题。历史上的国际秩序转型通常以暴力方式实现,旧的秩序被完全推翻,获胜大国及其集团围绕自身利益建立一套新的秩序安排。在当今时代,暴力方式难以为继,新兴大国只能通过一些相对和平的手段改变既有利益分配格局,以此推动秩序的渐进调整。进入21世纪以来,国际制度竞争成为国际秩序转型的核心动力,崛起国寻求提升在制度体系内的物质利益和规则主导权,守成国则试图利用制度体系内的优势地位维护既得利益。崛起国的制度竞争策略包括改革既有制度、创建新的包容守成国的制度和排斥守成国的制度,守成国针对崛起国的行动而制定相应的反制策略。双方的制度竞争通过改变既有利益分配的不同维度来决定国际秩序的转型模式。当前,中国通过改革既有制度和创建新的包容守成国的制度实现了物质利益和规则主导权的提升,中美两国在国际制度领域的持续互动将决定未来国际秩序转型的进程。     

Institutional quality and economic growth: Evidence from South-Asian countries

The current study investigates the relationship between institutional quality and economic growth, focusing on South-Asian countries entailing Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka, from 2002 to 2018. The data are analysed using the dynamic heterogeneous panel (panel autoregressive distributed lag [ARDL] model) approach, specifically the dynamic fixed effect (DFE), mean group (MG), and pooled mean group (PMG). Based on the findings, the three governance indicators, namely corruption control, accountability, and the rule of law, positively and significantly affect economic growth. All the nations have consistent long-run estimates but varied short-run estimates and adjustment speed for the long-term equilibrium. This is due to governance volatility that is evident in all the nations. This article offers both practical and theoretical contributions. This article contributes to the institutional quality and economic growth literature from a theoretical perspective from the South-Asian perspective. From a practical perspective, the study findings are significant for policymakers, particularly those from the countries that demonstrate major fiscal and external imbalance due to war and terrorism, low oil prices and weak trade. Hence, there is a pressing need to address economic growth issues instigated by the policymakers' negligence to ensure appropriate governance and macroeconomic management. Regulators can improve economic growth through national and regional image building by developing a stable economic and political landscape and maintaining macroeconomic stability by improving the institutional quality indicators. There is evidence that institutional quality improvement leads to better economic growth.     

Institutional shifts and punctuated patterns in digital policy

While digital policies provide significant value within contemporary governance, not many governments' digital policies are adapted to rapidly changing technologies and associated expectations. The limited adaptability can be explained by governments' focus on institutional shifts as an instrument to generate policy changes. Therefore, this article examines the impact of institutional shifts on digital policy by leveraging the Punctuated Equilibrium Theory (PET) as a lens to explore the Belgian federal government between 2000 and 2020. This is done through performing a distributional application of the PET and an explaining-outcome congruence case study. The results highlight the role of institutional shifts in directing digital policy, but also underscore the importance of other factors (i.e., policy image, attention allocation and/or structure of the political system) and the presence of policy entrepreneurs to explain the (in)stability of digital policy.
