基于区块链技术的建筑材料供应链质量数据安全共享方法

传统方法在建筑材料供应链质量数据安全共享中应用效果不佳，不仅数据误码率比较高，而且数据共享时延比较长，无法达到预期的数据安全共享效果。为此提出基于区块链技术的建筑材料供应链质量数据安全共享方法。利用区块链技术对建筑材料供应链质量数据属性加密，建立建筑材料供应链质量数据安全共享链，整合建筑材料供应链质量数据加密、解密程序，通过对用户身份验证实现对质量数据安全共享，以此完成基于区块链技术的建筑材料供应链质量数据安全共享。实验证明，设计方法的数据误码率在1%以内，数据共享时延在1s以内，具有良好的数据安全共享效果。     

转让方社会责任与主并方企业价值——主并方社会责任的中介效应检验

以并购事件为联结，设置企业社会责任、企业价值等主要变量，实证检验转让方企业社会责任与并购完成后主并方企业社会责任之间、主并方企业社会责任与其企业价值之间、并购前转让方企业社会责任与并购后主并方企业价值之间等三对关系。结果显示，上述三对关系均为显著正相关，且在并购前转让方企业社会责任与并购完成后主并方企业价值之间的关系中，并购完成当年主并方企业社会责任起到中介作用。     

Identifying Worldviews on Corporate Sustainability: A Content Analysis of Corporate Sustainability Reports

Companies commonly issue sustainability or corporate social responsibility (CSR) reports. This study seeks to understand worldviews of corporate sustainability, or the corporate message conveyed regarding what sustainability or CSR is and how to enact it. Content analysis of corporate sustainability reports is used to position each company report within stages of corporate sustainability. Results reveal that there are multiple coexisting worldviews of corporate sustainability, but the most dominant worldview is focused on the business case for sustainability, a position anchored in the weak sustainability paradigm. We contend that the business case and weak sustainability advanced in corporate sustainability reports and by the Global Reporting Initiative are poor representations of sustainability. Ecological embeddedness, or a locally responsive strategy that is sensitive to local ecosystems, may hold the key to improved ecological sensemaking, which in turn could lead to more mature levels of corporate sustainability worldviews that support strong sustainability and are rooted in environmental science. This must be supported by government regulation. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment     

Are they telling the truth? Revealing hidden traits of satisfaction with a public bike-sharing service

Public bike-sharing systems (BSSs) are an emerging mode of transportation introduced by municipalities to solve congestion problems in metropolitan areas, especially when integrated with other types of transportation. In the last years, the number of public bike-sharing services has been constantly on the rise all over the world, and generally the overall satisfaction with them is high. However, satisfaction with public services is driven by mechanisms that can differ from those in the private sector. It is important to establish to what extent a high satisfaction is genuine or simply ephemeral. Even “old” public services (like public transportation) become “gold” when accompanied by the introduction of new technologies. In this paper we analyze this phenomenon using data from a satisfaction web-survey conducted among customers of the public BSS “BikeMi” in Milan, Italy, in a period when mobile technologies have been introduced to speed up the service. On analyzing the responses to satisfaction questions using simple summary statistics, the level of satisfaction resulted very high. However, our aim was to look for potential “darker” sides of the service by detecting possible hidden satisfaction components. For this purpose, we used the Nonlinear Principal Components Analysis, which is particularly powerful in this context. A simple textual analysis was also performed as a validating test. Results from our analysis indicated that satisfaction is flawed by a set of factors like the mechanics of the bikes, the picking and dropping system, and the apps used to organize the service. Less concern was detected for more general aspects of the service.     

Online piracy in the context of routine activities and subjective norms

Why do mainstream consumers who would not typically engage in illegal behaviour routinely resort to online piracy of copyrighted software? This paper provides answers to this research query by applying routine activity theory and the theory of reasoned action. The paper’s study analyses consumers’ role as possible offenders that can have the opportunity to engage in online software piracy as part of their routine online activities. Although it is problematic to measure the exact magnitude of the negative impact on the US economy, as stated by the Government Accountability Office it is sizeable. After analysing the conceptual model using a US national consumer sample of over 700 consumers, results show the influence of proximity to motivated offenders, target suitability, and capable guardianship on consumers’ attitudes and perceived subjective norms towards online software piracy, as well as their intentions to engage in this illegal behaviour on the Internet. By integrating routine activity theory, a criminology theory with the theory of reasoned action from psychology and analysing a widespread online software piracy phenomenon, several academic and practical contributions are made.     

Supply Chain Integrity: A Key to Sustainable Supply Chain Management

As stakeholders continue to increasingly hold firms accountable for environmental and social performance in their supply chains, the importance of understanding how firms can be more sustainable becomes more prescient. Based on the underlying premise of stakeholder theory that business and ethics decisions are intertwined, the current research introduces the concept of supply chain integrity (SCI) to explore how the interdependence of business and ethics decisions can lead to improvements in sustainable supply chain management (SSCM) practices. Exploratory analysis employing secondary data sources in an elastic net (EN) logistic regression provides support for the proposed construct, by providing preliminary empirical evidence that SCI, measured through two subdimensions of structural and moral SCI, can be linked to firm sustainability. The research contributes to the supply chain management literature by: (1) introducing the concept of SCI; (2) performing an exploratory econometric analysis to provide initial validity of the SCI construct; and (3) providing a research agenda to guide further research on the concept of SCI and its role in SSCM.     

信息分享对原始设备制造商与其合同制造商竞争的影响

研究了原始设备制造商的预测信息分享对一个原始设备制造商和一个与其同时有合作和竞争的合同制造商组成的供应链系统的影响,建立制造商间信息分享的模型,该模型包括一个原始设备制造商和一个合同制造商。研究发现,原始设备制造商关于市场潜在需求预测信息的分享对其预期利润是不利的,同时需求信息预测的精度对原始设备制造商信息分享的决策也有影响,原始设备制造商没有动机与其供应链成员进行信息分享,但信息分享使得供应链整体利润增加。最后,建立一个信息分享补偿机制分享供应链利润的增加量,以期通过信息分享补偿机制促使原始设备制造商有动机进行信息分享,从而实现其与合同制造商的“双赢”。     

Corporate social responsibility in international hotel chains and its effects on local employees: Scale development and empirical testing in China

This study aims to investigate the corporate social responsibility (CSR) practices of international hotel chains operating in China and their effects on local Chinese employees. As CSR practices vary across countries and contexts, this study developed a scale of CSR metrics, which was based on CSR reports published by international hotel chains in China and a comprehensive literature review. Subsequently, the proposed model, which depicts the relationships between CSR practices and local employee work metrics, was tested with a PLS-SEM. Multiple phases of qualitative and quantitative investigations of 2451 local Chinese employees of international hotel chains allowed for validating a formative construct of CSR with four dimensions: environment protection, employee wellness, business ethics, and customer wellness. The PLS-SEM results confirmed the significant effects of CSR practices of international hotel chains in China on local Chinese employee engagement, commitment, job satisfaction, and organizational citizenship behaviors. Theoretical and practical implications are presented.     

Cause-related marketing persuasion research: an integrated framework and directions for further research

This paper presents an integrative review of the literature on cause-related marketing (CRM) persuasion research (i.e. studies of how CRM influences evaluations of the partner brand). The aim of the study was to review CRM persuasion research and to integrate the findings into a theoretical framework that could direct future research efforts in the area. Drawing on Bergkvist and Taylor's model of Leveraged Marketing Communications (LMC), a dual-path model of CRM persuasion effects was developed. According to the model, CRM affects brand evaluations along two paths: the indirect transfer path which is mediated by attribution of motives and the direct transfer path in which attitude towards the cause is transferred to the brand. The model incorporates results from extant research and provides guidance for future studies.
