This study examines the dynamic relationships of visit behavior in the multiple channels [personal computer (PC) and mobile channels] on online store sales performance.

Abstract

Purpose

This study examines the dynamic relationships of visit behavior in the multiple channels [personal computer (PC) and mobile channels] on online store sales performance.

Design/methodology/approach

The empirical data were from an online store for the period between August 14, 2015 and May 15, 2016. The data consisted of consumer visit behavior and online store sales performance. Vector autoregression with an exogenous variables model was adopted to investigate the dynamic relationships.

Findings

The empirical results show significant relationships between visit behavior metrics (number of visitors, average number of visits per visitor and average length of each visit) in the two channels and online store sales performance. The number of visitors through the PC and mobile channels strongly and positively affects online store sales performance both in the short term and in the longer term. Moreover, the number of visitors in the PC channel has the strongest influence on sales performance metrics, followed by the number of visitors and the average number of visits in the mobile channel. The PC channel's visit behavior metrics explain a larger proportion of the sales performance variance than that in the mobile channel.

Originality/value

The previous literature on consumer behavior in multichannel marketing mainly focuses on channel selection or migration, and examines the different factors affecting channel choice behavior. Little is known about the impacts of visit behavior in the multiple channels. This study adopts the heuristic-systematic information processing theory to unveil the impacts of visit behavior metrics in the PC and mobile channels on online store sales performance.

Abstract

Purpose

The extensive distribution of fake news on the internet (FNI) has significantly affected many lives. Although numerous studies have recently been conducted on this topic, few have helped us to systematically understand the antecedents and consequences of FNI. This study contributes to the understanding of FNI and guides future research.

Design/methodology/approach

Drawing on the input–process–output framework, this study reviews 202 relevant articles to examine the extent to which the antecedents and consequences of FNI have been investigated. It proposes a conceptual framework and poses future research questions.

Findings

First, it examines the “what”, “why”, “who”, “when”, “where” and “how” of creating FNI. Second, it analyses the spread features of FNI and the factors that affect the spread of FNI. Third, it investigates the consequences of FNI in the political, social, scientific, health, business, media and journalism fields.

Originality/value

The extant reviews on FNI mainly focus on the interventions or detection of FNI, and a few analyse the antecedents and consequences of FNI in specific fields. This study helps readers to synthetically understand the antecedents and consequences of FNI in all fields. This study is among the first to summarise the conceptual framework for FNI research, including the basic relevant theoretical foundations, research methodologies and public datasets.

Abstract

Purpose

Although there have been considerable discussions on the business value of adopting blockchain in supply chains, it is unclear whether such blockchain-enabled supply chains (BESCs) can help firms mitigate the negative impact resulting from the recent COVID-19 pandemic. This study aims to answer this important question.

Design/methodology/approach

The authors conduct an event study to quantify the financial effects of the COVID-19 pandemic and compare the differences in such effects between treatment firms that have adopted BESCs and matched control firms that have not adopted BESCs. The authors also perform a regression analysis to examine how the role of BESCs in mitigating COVID-19's negative impact varies across firms with different levels of supply chain leanness and complexity. The analysis is based on 88 treatment firms and 88 matched control firms, all of which are publicly listed on the US stock markets.

Findings

The test results suggest that although both the treatment and control firms are negatively affected by the COVID-19 pandemic, the effect is less negative for the treatment firms compared to the control firms, demonstrating the role of BESCs in mitigating the negative impact caused by the COVID-19 pandemic. Moreover, the mitigating role of BESCs is more pronounced for firms with lean and complex supply chains.

Originality/value

This study is among the first to provide empirical evidence on the mitigating role of BESCs during the COVID-19 pandemic, highlighting the importance of adopting blockchain in supply chains with high uncertainties and disruption risks.

Abstract

Purpose

The purpose of this paper is to propose a new approach recommending friends to social networking users who are also using weight loss app in the context of social networks.

Design/methodology/approach

Social network has been recognized as an effective way to enhance overweight and obesity interventions in past studies. However, effective measures integrating social network with weight loss are very limited in the healthcare area. To bridge this gap, this study develops a measure for friend recommendation using the data obtained by weight loss apps; designs methods to model weight-gain-related behaviors (WGRB); constructs a novel “behavior network;” and develops two measurements in experiments to examine the proposed approach.

Findings

The approach for friend recommendation is based on Friend Recommendation for Health Weight (FRHW) algorithm. By running this algorithm on a real data set, the experiment results show that the algorithm can recommend a friend who has a healthy lifestyle to a target user. The advantages of the proposed mechanism have been well justified via comparisons with popular friend recommenders in past studies.

Originality/value

The conventional methods for friend recommenders in social networks are only concerned with similarities of pairs rather than interactions between people. The system cannot account for the potential influences among people. The method pioneers to model a WGRB as recommendation mechanism that allow recommended friends to simultaneously fulfill two criteria. They are: first, similarity to the target person; and second, ensuring the positive influence toward weight loss. The second criterion is obviously important in practice and thus the approach is valuable to the literature.

Abstract

Purpose

In recent years, social media have attracted considerable attention. Hence, the purpose of this paper is to conduct a critical literature review of social media research with the aim of developing a conceptual framework to explain how social media applications are supported by various social media tools and technologies and underpinned by a set of personal and social behavior theories or models.

Design/methodology/approach

This study adopted a two-stage approach. The first stage involves a critical literature review of academic journals in social media research, followed by the proposal of a conceptual framework that highlights the tools and technologies as well as theories and models that serve as the foundation of social media applications. The second stage involves the use of an actual case to demonstrate how the proposed framework facilitates the development of a social media application for a regional division of an international non-government organization.

Findings

The literature review indicated that social media have been applied in diverse business areas with the support of various social media tools and technologies and underpinned by a range of personal and social behavior theories and models. Based upon such findings, a conceptual social media application framework was devised and its usability illustrated via a real-life case study. Managerial implications are also discussed.

Research limitations/implications

Social media covers a wide range of research topics and thus, the literature review presented in this study may not be exhaustive. Nevertheless, the proposed framework and case study can both serve as reference for future research and provide recommendations for practitioners in the design and development of their own social media applications.

Practical implications

This study not only explains the importance of applying social media in various business sectors, but also enhances the understanding of the infrastructure of social media applications. The study also provides insights for improving the efficiency of application solutions. Organizations are advised to adopt social media in their business based on the proposed conceptual framework.

Originality/value

With a literature review of social media research and a real-life case study, this study presents a conceptual framework using extant theories and models to form a foundation for social media applications. The framework extends existing knowledge on the design and development of information systems.

Abstract

Purpose

The purpose of this paper is to examine the problems encountered by clothing merchandisers in managing fabric sample resources, and analyses their expectations of and requirements for a desirable management solution. It then aims to consider the architectural design of an intelligent fabric sample management system prototype, and the development of a construction and implementation plan for a fashion enterprise to install the system.

Design/methodology/approach

A three‐stage methodological approach is adopted. The first stage is a preliminary study using in‐depth interviews with potential system users; the second involves the architectural design of a five‐component system prototype; and the third develops a multi‐phase construction and implementation plan using a case study.

Findings

Four categories of problems in the management of fabric sample resources are identified, the system architecture is designed, and a construction and implementation plan is proposed. Managerial and theoretical implications are also discussed.

Practical implications

The design process of the research and development (R&D) framework enables fashion enterprises to obtain a deeper understanding of their operations in managing fabric samples and to make wiser decisions in resource allocation. By taking the specific needs of system users into consideration, system solution developers are able to design tailor‐made software packages that are intelligent, user‐friendly and user‐oriented.

Originality/value

Through a logical and systematic process of designing the R&D framework, the paper identifies some “technological rules” which links up the practice of solving an industrial problem with the formulation of substantive theories. This adds to the application of design science research.

Abstract

Globalization and the borderless marketplace have created an opportunity for companies to come together to work on projects that could otherwise not be completed through the efforts of one or two companies acting independently. The formation of virtual enterprise networks combines the advantages of the various core competencies of members of the network to deliver customer satisfaction. Virtual enterprise networks consist of several firms that can be geographically dispersed, and that might be technically disparate in terms of system platforms. Coordination among members of the network and the the transfer of quality products and services among members of the network are the key factors in achieving success. The proposed framework presented in this paper utilizes a multi‐agent model to monitor quality within a virtual enterprise network to ensure that the processes among members run smoothly and efficiently.

Abstract

Purpose

The vast majority of evidence about knowledge management (KM) is based on studies within a mass‐producing context and at intra‐organizational level. Little has been reported in the complex products and systems (CoPS) literature about KM processes across firm boundaries. To contribute to this gap, this paper reviews the literature of CoPS, inter‐organizational collaboration and KM, discusses some challenges of inter‐organization KM faced by CoPS manufacturers, and explores a research framework which is helpful to provide a preliminary understanding of inter‐organizational KM within a CoPS context.

Design/methodology/approach

Literature review and research experience are presented.

Findings

The study has identified some challenges faced by CoPS manufacturers when they try to manage knowledge from an innovative network, and developed a framework extending KM processes into an inter‐firm collaborative network for CoPS development. Both, project level collaboration and firm level linkages need to be taken into consideration when attempting to implement KM at inter‐organizational level. Knowledge acquisition from network, knowledge integration, and knowledge sharing in the network are the main inter‐organizational KM activities in a CoPS context.

Originality/value

As KM based on inter‐organizational collaboration has received little attention in prior studies, especially in CoPS conditions, this study is an exploratory discussion of KM issues within a CoPS context, combining the cross‐school theories of inter‐organizational linkages, KM and CoPS innovation. This paper tries to account for knowledge‐related activities involved in CoPS development, identifying some challenges in CoPS innovation.
