一水邻苯二甲酸钙的热分解及其脱水动力学分析

采用TG-DTA分析研究了一水邻苯二甲酸钙热分解过程,对其中的脱水过程进行了动力学计算. 由Friedman和Ozawa-Flynn-Friedman法得到脱水过程的活化能和指前因子,用Archar方法计算拟合了几种机理函数,确定了脱水过程的优化动力学参数及最佳机理模型. 脱水过程的活化能Ea为141.1576 kJ/mol,反应的机理模型为Bna,即f(α) =(1-α)n*αn.     

Diels—Alder反应机理浅析

本文分析了D—A反应的三种反应机理,即完全的一步协同机理、分步机理和不对称的协同机理,着重分析了完全的一步协同机理,并指出大部分D—A反应按此机理进行。     

工学交替培养机制探析

职业教育实行工学交替势在必行。对其进行机制分析,是非常必要和及时的。市场、政策、评价“三维导向”机制,阐释了工学交替诞生的必然性、规范性和可能性;企业、学校、学生“三方共赢”机制,解释了三方在实施工学交替中的共生共荣效应;用长效、保障、激励机制,从可持续发展、管理、法规政策层面进行了相关问题透析,探索了工学交替一些运作举措。     

理性与证据制度:一个初步性的讨论

理性传统一直是西方文明中的核心命题,它对整个西方文明产生过深远影响。作为西方文明重要组成部分的法律文明也深受其影响,不仅法律本身是理性的产物,而且一些构成法律制度基础的自然法学与实证主义法学都是理性话语的产物。同样证据制度的形成与演化以及具体运用也都在理性的作用下展开。     

组织内知识共享信任机制的发展路径和改善方法研究

随着全球化、网络化经济的出现,知识管理越来越受到重视。然而在知识管理的实践过程中,还缺少对组织内知识共享信任机制的深入研究。本文在前人对知识共享和信任机制研究的基础上,从“质”的角度——信任形式和“量”的角度——信任半径分析出组织内知识共享信任机制的发展路径,并在此基础上从组织制度和组织文化两个角度提出具体的改善方法,用于改进组织知识共享行为,提升企业的知识管理实践能力。     

论新手教师和专家教师的合作对新手教师专业成长的影响机制

新手教师和专家教师的合作是一种推动新手教师专业化成长的有效途径,合作因为类型、性质、层次的不同而形成不同的运行机制,相应地会对新手教师的专业成长产生不同的影响。完善学校管理制度、构建教师合作的文化氛围、优化教师合作过程、培养教师的合作素养,是实现新手教师和专家教师高层次、规范合作以促进新教师专业成长的有效策略。     

《江门市志·宗教》勘误

《江门市志》及先其编成的《江门百年大事记（1854--1993）1对江门赖神会创立经过之记栽颇多舛误。赖神漫信会创立人之一冼锡鸿1941年手稿①《赖神缘起》、《本赖神会史略》对该会之创立经过有详尽描述,借助冼锡鸿手稿及其他相关材料,可使《江门市志》及“百年大事记”的舛误得以勘正。

A framework for analysing blockchain technology adoption: Integrating institutional,market and technical factors

The adoption of blockchain technologies require the consideration of a broad range of factors, over and above the predominantly technology focus of most current work. Whilst scholarly literature on blockchain technology is only beginning to emerge, majority are focused on the technicalities of the technology and tend to ignore the organizational complexities of adopting the technology. Drawing from a focused review of literature, this paper proposed a conceptual framework for adoption of blockchain technology capturing the complex relationships between institutional, market and technical factors. The framework highlights that varying outcomes are possible, and the change process is focal as this shapes the form blockchain applications take. Factors presented in the framework (institutional, market and technical) interact and mutually influence each other. The proposed framework can be used by organisations as a reference point for adopting blockchain applications and by scholars to expand, refine and evaluate research into blockchain technology.     

Blockchain in the operations and supply chain management: Benefits,challenges and future research opportunities

Blockchain technologies have captured the imagination of scholars, managers, and practitioners around the world. It is widely accepted by these actors that blockchain is not a buzzword, but a highly disruptive technology that is already remodeling the organizations and their supply chain business models. Despite the meaningful advance in the last years, blockchain applications regarding the operations and supply chain management (OSCM) are still in their infancy. Little is known about the role of blockchain in terms of operations traceability, as well in areas such as e-commerce, agriculture, public services, etc. Therefore, this Special Issue seeks to extend our understanding of blockchain applications in OSCM and how firms create and capture business value with blockchain. To this effect, this Special Issue will provide a well-articulated and in-depth discussion of the role of blockchain in creating value in the domain of OSCM. Specifically, it is expected that more light is shed on how blockchain integrates with and impacts new business models, transforms relationships, and improves performance and competitive advantage in OSCM. Also, the evolution of blockchain was reviewed in order to provide a strong background to the readers. The literature review was performed taking into account a bibliometric perspective of blockchain-related publications. The review supports the importance of this Special Issue by highlighting the urgent needs of this topic in this reputable journal. Finally, we provide future research directions and a guide for the papers presented in this Special Issue.
