Practical Implications

Purpose The purpose of this paper is to examine existing literature, including both academic and practitioner publications, related to Canadian SOX (or C-SOX as it is popularly known). The study discusses the origins of the Act, the underlying motivations for enacting this legislation in Canada and its impact on corporate decisions since its inception in 2003. Design/methodology/approach The principal focus of this literature review is on C-SOX, its inception, reception, compliance and impact in Canada, both from business’ and investors’ critical perspectives. The authors have followed a two-step process to gather all the articles. First, the authors used a keyword search at Google Scholar and ProQuest (e.g. C-SOX, Canadian SOX, Bill 198, etc.) to gather all the articles. Second, the authors retained articles and abstracts that primarily dealt with the background framework and impact of the legislation. It is to be noted that C-SOX was mainly a reactionary legislation following the adoption of US-SOX in 2002. Any discussion of C-SOX is, therefore, incomplete without referencing the literature related to US-SOX. Findings In this review paper the evolution of C-SOX over time in Canada, as well as studies on its impacts and criticisms have been summarized. Based on the extensive research that followed the enactment of US-SOX, the authors also provide suggested research directions related to C-SOX in the future. Research limitations/implications C-SOX has been relatively underexplored and therefore, not much academic work is available presently. This study highlights this gap in the literature with the hope that researchers will devote their energy to understanding the broader ramifications of major legislations such as C-SOX which will potentially also inform future public policy choices. Practical implications This research will help both businesses and investors to understand each other’s perspectives and concerns regarding C-SOX. This paper will also be helpful to policy makers to identify potential areas of improvement in this and future legislative decisions in the future. Originality/value Using a qualitative approach this study combines the development of C-SOX as a legislation in Canada, its overall effectivity/drawbacks and explores the areas it impacts, both positively and negatively, along with criticisms and appreciations.

Purpose In the crowd intelligence networking era, the smart connections of human, machines and things enable point-to-point trustable transactions and distributed efficient collaboration; the smart connections among government, enterprises, organizations and the public would enable active participation of the public in society management and decision-making and improve the efficiency of government management and services. All interactions among various agents can be viewed as the transaction activity. The social division of labor system drives the evolution of transaction. The transaction mode also differentiated into different patterns with the development of human society. What will be the intelligent transaction in the crowd intelligence networking era? What will be the transactions modes and rules in the crowd intelligence networking era? The answers to these questions are of great importance to the future development of transactions. Design/methodology/approach The authors review the evolution of traditional transaction and transaction modes and analyze the driving forces of it. They attempt to give the definitions of intelligent transaction and intelligent transaction mode. They also review the traditional transaction modes and rules, analyze the characteristics of the intelligent transaction and classify the intelligent transaction modes. Findings The authors find the intelligent transaction is mainly reflected in the intellectualization of transaction subject, transaction object and transaction process. They summarize the characteristics of intelligent transaction and develop four modes for the intelligent transactions based on the modularization level of the transaction objects and the quantity of transaction subjects, including the demand side and the supply side. The authors also show representative examples to further illustrate rules and features of these transaction modes and point out the potential research directions. Originality/value This study is among the first to analyze the characteristics of the intelligent transaction, and the proposed division framework of the intelligent transaction modes could not only add value to the future research of intelligent transaction modes and rules but also help to guide the transactions in the crowd intelligence network.

Purpose The purpose of this paper is threefold. First, it describes the general characteristics of studies on logistics and supply chain education (L&SCE). Second, it classifies identified papers on the basis of their main research methods and issues. Finally, it proposes some meaningful directions for future research. Design/methodology/approach Seventy-three papers published since 2000 in international peer-reviewed journals were reviewed using a systematic review methodology. The collected papers were analyzed and classified on the basis of research methods and issues. Findings It was found that most papers on L&SCE were published in journals in the logistics and supply chain management field and were conducted by either a single or mixed-method approach. The survey-based approach was the most preferred method. The contribution of this study is twofold. First, the identification of the five competencies and 49 skills required of logistics and supply chain talents was performed along with the analysis of the 42 courses and the teaching methods. Second, this study revealed some important aspects that have received inadequate attention in the literature and proposed potential research directions. Originality/value This paper provides academics and practitioners alike with a guide to extant literature. The proposed framework of the competencies and skills required of talents could be a guide to develop competence in both students and employees. The summary of the curriculum and the matrix of relationships between the relevant courses and competencies can be used by educators to improve L&SCE. Finally, the proposed research directions are meaningful for academics.

Cyber Risk

Purpose This paper aims to provide an overview of the main research topics in the emerging fields of cyber risk and cyber risk insurance. The paper also illustrates future research directions, from both academic and practical points of view. Design/methodology/approach The authors conduct a literature review on cyber risk and cyber risk insurance using a standardized search and identification process that has been used in various academic articles. Based upon this selection process, a database of 209 papers is created. The main research results findings are extracted and organized in seven clusters. Findings The results illustrate the immense difficulties to insure cyber risk, especially due to a lack of data and modelling approaches, the risk of change and incalculable accumulation risks. The authors discuss various ways to overcome these insurability limitations, such as mandatory reporting requirements, pooling of data or public–private partnerships in which the government covers parts of the risk. Originality/value Despite its increasing relevance for businesses at present, research on cyber risk is limited. Many papers can be found in the IT domain, but relatively little research has been done in the business and economics literature. The authors illustrate where research stands currently and outline directions for future research.
