IT架构柔性对顾客参与的驱动影响——顾客类型的调节效应

将IT架构柔性解构为技术IT架构柔性和人员IT架构柔性,构建了IT架构柔性驱动顾客参与框架模型,并利用针对中国制造企业的问卷调查数据,检验IT架构柔性的两个维度对顾客参与的驱动影响,以及顾客类型在其中的调节效应。结果表明:技术IT架构柔性和人员IT架构柔性对顾客参与具有积极的驱动作用;顾客类型在人员IT架构柔性对顾客参与的积极驱动影响中发挥显著的调节效应,但在技术IT架构柔性对顾客参与的驱动影响中的调节效应不显著。     

气相色谱法测定人工合成煤气中氧含量

本文介绍了采用气相色谱法测定人工合成煤气中氧含量的分析方法,采用TDX-01(50~80目)色谱柱,外标法定量,测定氧含量。结果表明,本方法线性相关系数0.9998,检出限0.01%,平均回收率96.2%。比目前普遍采用的奥式气体吸收法、色谱法(两阀两柱),精密度高。该方法快速、简便,适合现场测定人工合成煤气中的氧含量。     

基于某工程边坡坍塌事故的分析研究

目前,建筑物的基坑开挖深度越来越深,对于基坑的支护也提出了更高的要求。基坑工程一直是建筑施工的重点,也是安全事故多发环节。本文以某工程基坑事故为例进行详细分析,对其发生事故后的支护加固措施进行研究,希望以对基坑工程合理设计与安全施工有所启示与帮助。     

外部监督与盈余管理——针对媒体关注、机构投资者与分析师的考察

从外部公司治理的角度,研究了媒体关注、机构投资者、分析师等外部治理因素对公司盈余操控行为的监督作用。研究发现：控制其他因素之后,越多的新闻报道伴随着越严重的盈余管理行为,新闻媒体能够发现、揭露上市公司的盈余管理行为,但是没有纠正功能;机构投资者交易越活跃,持股比例越高,公司盈余的操控程度越小,说明机构投资者对公司的盈余...     

HR flexibility: Precursors and the contingent impact on firm financial performance

Using data from 170 for‐profit U.S. firms with 100 or more employees from 27 North American Industry Classification System (NAICS) industry subsectors, we investigated firm‐level precursors of HR flexibility and industry‐level boundary conditions of the HR flexibility—firm financial performance relationship. The findings denote that a contingency illumination is warranted in which consideration should be given to firm‐level factors such as flexibility business strategy and high‐performance work systems, which may play a key role in engendering HR flexibility, and external factors such as industry dynamism and growth, which may serve as boundary conditions that influence the relevance and impact of HR flexibility. This study is an important extension of extant HR flexibility research and adds clarity regarding the roles and relevance of HR flexibility and the circumstances in which HR flexibility and/or its focal factors may augment (or diminish) firm competitiveness and performance.     

分析师跟踪、董事海外背景与信息披露质量

信息披露真实、准确、完整是资本市场的基石，是投资者、债权人决策的重要信息来源。本文以2010-2017 年中国沪深A 股上市公司为样本，研究机构投资者、分析师等外部监督角色，以及作为内部治理核心的董事会包括董事海外背景等重要特质是否能显著提升上市公司信息披露质量。本文实验结果表明：外部治理变量分析师跟踪度和董事会特征变量董事海外背景对公司信息披露质量有显著的正相关影响，信息披露质量评定机构可以通过使用外部监督和内部董事会特征的公司治理信息，来提高信息披露质量的准确性和可信度。本文聚焦外部治理和内部治理这两个关键与核心治理部位，将它们与企业信息披露质量放在同一个理论框架中，通过多种信息披露质量衡量方法，针对分析师的外部监督治理作用的视角和董事海外背景这两个重要变量进行研究，为提升上市公司信息披露质量提供实证启示.     

Holding back from theory: limits and methodological alternatives of randomized field experiments in development economics

ABSTRACT

In this paper, we critically and constructively examine the methodology of evidence-based development economics, which deploys randomized field experiments (RFEs) as its main tool. We describe the context in which this movement started, and illustrate in detail how RFEs are designed and implemented in practice, drawing on a series of experiments by Pascaline Dupas and her colleagues on the use of bednets, saving and governance in Kenya. We show that this line of experiments have evolved to address the limitation of obtaining policy-relevant insights from RFEs alone, characterized as their lack of external validity in the literature. After examining the two prominent responses by leading figures of evidence-based development economics, namely machine learning and structured speculation, we propose an alternative methodological strategy that incorporates two sub-fields, namely experimental economics and behavioral economics, to complement RFEs in investigating the data-generating process underlying the treatment effects of RFEs. This strategy highlights promising methodological developments in RFEs neither captured by the two proposals nor recognized by methodologists, and also guides how to combine different sub-fields of economics.     

Research on extended external reporting assurance: Trends,themes, and opportunities

The assurance of non‐financial information (NFI) included in extended external reports (EERs) is a global activity that has far‐reaching consequences for business, investors, other stakeholders, and society. EERs remain largely unregulated with few standards. Along with our companion paper (Krasodomska, Simnett, & Street, 2021, Journal of International Financial Management and Accounting, 25, 209), we contribute to the current discussion on EER assurance by providing an overview of the academic literature to inform the standard setting initiatives of the International Auditing and Assurance Standard Setting Board (IAASB), as well as the practice of assurance of EERs. We identify 121 articles on extended external reporting (EER) assurance published between 2009 and 2020 across 35 journals ranked A*, A, and B on the Australian Business Deans Council (ABDC) 2019 Journal Quality List. These articles cover archival, experimental, interviews, case studies, surveys, and content analysis research methods and serve as a possible input for standard setting activities. We document a rapid increase in this literature with almost half of the articles published in the last 3 years, 2018 to 2020. Finally, we offer ideas for future research directly linked to the proposed Guidance of the IAASB on EER assurance. We encourage researchers to engage in these and other issues of the IAASB’s Guidance to assist them with valuable input for their standard setting activities.
