Far from Well: The UK since COVID-19, and Learning to Follow the Science(s)*

This paper offers a five-part framework for assessing why the United Kingdom has coped poorly compared with peer countries with the medical, social and economic challenges brought by the COVID-19 pandemic – a surprising failure, given the strength of its scientific community and the internationally attested quality of its civil service. The paper also offers a proposal for how to shape an independent inquiry, one promised by the UK Prime Minister, of the kind that has the primary motivation to better prepare the country for future crises. The paper begins by providing various metrics that set out how the UK has, as of late 2020, been particularly adversely affected by the pandemic. It then details the five-part framework, which is presented as a series of propositions with initial supporting evidence that require more thorough investigation, supported by a fuller record of evidence. First, we suggest that there have been problems as to how evidence about the pandemic and its anticipated effects was collected, processed and circulated, weakening policymakers’ ability to evaluate the risk calculus. Second, particular structures and processes of government decision-making appear to have been inadequate and ill-suited to the multidimensional challenges brought by the pandemic. Third, the role of political leadership and decision-making in the public health and broader policy responses needs thorough evaluation. Fourth, we assess some aspects of economic policymaking during the pandemic. Fifth, features of the UK's institutional make-up may have been a driver of the suboptimal outcomes. Overall, we argue that UK policymakers may have over-relied on the medical sciences at the expense of other (social) scientific evidence.     

资本化研发支出减值传递了什么信号

研究以2007-2019年进行过研发支出资本化的A股上市公司为对象,从上市公司、外部投资者和交易所监管者三个维度,对开发支出减值的经济后果进行了检验。结果显示开发支出减值传递了开发支出质量较低的信号,监管者能在减值年度有效接收信号并发放含相关问题的年报问询函进行监管,但投资者未能正确解读减值信号。进一步分析发现减值计提并未达到提升开发支出质量的目的,而信息环境优化有助于投资者正确接收开发支出减值所蕴含的信息。以上发现对于研发支出资本化会计准则的细化完善、开发支出减值机会主义行为的治理、资本市场对开发支出信息解读和吸收效率的提升等,具有一定的借鉴意义。     

创业板高科技股票IPO报价行为的博弈分析

建立一个发行人和询价对象的动态博弈模型,分析询价对象在创业板高科技股票IPO询价阶段的报价行为。得出询价对象存在报价偏差行为的结论：当预期锁定期后公司股价看涨时,询价对象报价存在正偏差;反之相反。     

基于演绎面向对象数据库的查询语言

演绎数据库(DDB)和面向对象数据库(OODB)已分别沿着不同道路独立地发展,并取得了许多成果。DDB研究和OODB研究具有很大的互补性,要将两者结合起来。演绎数据库和面向对象数据库是传统数据库技术的重要扩展,通过用固定逻辑基础的递归和声明查询,演绎数据库扩展了传统数据库的表达能力。但演绎数据库缺乏强大的数据建模能力,而面向对象数据库缺乏逻辑语义和声明查询语言。在下一代信息系统中组合面向数据(结构化)、行为和演绎是必要的,但用户查询语言应含有高级面向对象和演绎原语的集合。     

Relationship learning at trade shows: Its antecedents and consequences

In spite of the increasingly recognized role of trade shows as a highly cost-effective medium, there are few established guidelines on how to capitalize on these meeting occasions. The relational view of competitive advantage, however, identifies relationship learning as an important avenue for creating differential advantage and supernormal profits in relationships. The purpose of this study is to develop a theoretical model explicating relationship-based learning activities growing out of trade shows, its determinants and performance effect. Specifically, it examines the roles of relationship properties of trade show participants, and collective inquiry approaches used for trade shows, in fostering learning between exhibitors and visitors. The model was tested by a sample of 414 exhibitor-visitor relationship dyads identified at specific trade shows. The direct effect of relationship commitment, consensus, and collective inquiry on relationship learning at trade shows was confirmed. The powerful influence of relationship learning activities on relationship performance outcomes as perceived by exhibitors at trade shows was substantiated.     

破坏自然资源犯罪构成特征及其视点探究

大多数学者论述环境犯罪都是以污染环境犯罪为例,并且涵盖了破坏自然资源保护犯罪,这种现象可能导致破坏自然资源保护犯罪中一些潜在的问题无法提升至法理层面进行探讨。基于破坏自然资源与污染环境两种类型犯罪的构成特征比较,指出破坏自然资源犯罪探究视点,以期引起学界关注和探讨。     

探究式教学——高职院校职业道德教育的主要模式

探究式教学是教师根据课堂教学的实际需要,由学生自主探索、自主分析、自主建构获取知识,灵活应用于具体教学中的一种教学方法。通过分析探究式教学模式所坚持的三个原则,提出高职院校职业道德教育要努力做好"四个构建",即构建恰当的教学角色、良好的合作模式、合理的考核体系、科学的评价机制。     

浅谈英语报刊阅读教学中的探究式策略

探究式教学强调学生知识的自主构建和学生自主学习的沟里.可从课前、课中和课后各教学过程分析探究式教学策略是如何激发学生的探究欲望,发掘学生探究潜能,提高学生知识自主建构的能力的.在英语报刊阅读课程中运用探究式教学,既要求教师有很好的理论联系实际和用英语发现问题的能力,也需有学生自主构建知识的欲望,只有两者达到有效统一,才能达到较理想的课堂效果.     

多媒体在物理探究型新授课的应用研究——《压强》教学设计

随着素质教育的发展和教育信息化的推进,信息技术与课程整合作为一种新的教学模式正日益受到广大教师的关注。虽然对整合问题专家和学者有大量的研究理论,但是与具体学科的整合实践理论和实施策略的研究还不够深入和全面。本文将着力探讨信息技术与初中物理探究型课型整合的模式作探讨,并提供教学实践案例供大家参考。     

有限理性监管、初步询价和IPO定价效率

在询价机制中加入初步询价阶段是我国累计投标询价机制区别于国际通行做法的主要特征。作为定价源头,初步询价为定价提供了最重要信息。本文从询价规则本身合理性出发,研究了初步询价在定价程序中的关键作用。研究发现,监管者的有限理性导致询价规则本身存在缺陷;由初步询价得到的初始价格区间主要受到询价家数、筹资额和市场整体回报影响,研究结果不同于成熟市场的结论;由于询价规则存在歧视性分配机制缺失、发行价受到控制和初步询价报价无有效约束等缺陷,初步询价没有改善定价效率。
