This study aims to examine users’ experiences and perceptions associated with the use of two wiki variants in the context of collaborative learning and knowledge management in higher education.

Participants included two groups of postgraduate students from a university in Hong Kong who used MediaWiki (n=21) and TWiki (n=16) in completing course requirements. Using a multiple case study approach and a mixed methods research design, data logs on the wiki platforms were downloaded and the contents were analysed. Students’ perceptions were examined through a survey.

The findings indicate that both wikis were regarded as suitable tools for group projects, and that they improved group collaboration and work quality. Both wikis were also viewed as enabling tools for knowledge construction and sharing.

This study provides insights that may inform the decisions of educators who are considering the use of wikis in their courses as a platform to enhance collaborative learning and knowledge management.

Previous research has shown that wikis can be effectively used in education. However there are a number of wiki variants and it may be difficult to identify which variant would be the best choice. There is a dearth of research comparing the effectiveness of different types of wikis. This study compares two wiki variants on a number of outcomes which may provide some insights to teachers who are in the process of selecting an appropriate wiki for teaching and learning.

This paper aims to investigate whether intellectual capital (IC) has an impact on the financial aspects of organizational performance as well as attempting to identify the IC components that are associated with corporate financial performance indicators that signal organizational growth.

This study drew on financial data from publicly available annual reports of all the constituent companies of the Hang Seng Index of the Hong Kong Stock Exchange for the years 2001‐2009. Following the value added intellectual coefficient™ (VAIC) methodology, regression models were constructed to examine the relationships between IC and the corporate financial performance indicators.

Evidence was found to suggest that IC, as measured by VAIC, was positively associated with profitability of businesses. In particular, structural capital, as a key component of IC, played a notable part in enhancing corporate profitability, and showed a growing trend in its significance. Empirical findings, based on correlation and linear multiple regression analysis, indicated that the components of VAIC were strong predictors of corporate financial performance such as return on equity and profitability. In particular, capital employed efficiency (CEE) was a significant predictor of all four corporate financial performance indicators.

The results may extend the understanding of the role of IC in business operations in Hong Kong, and may help to identify the specific IC drivers that may have a direct impact on the financial performance of these companies. In particular, although CEE was a significant predictor of all four corporate finance performance indicators, the increasing contribution of structural capital efficiency (SCE) in predicting ROA and ROE was observed. The role that structural capital plays in strengthening business performance warrants further investigation.

There has only been one previous empirical study on the intellectual capital of constituent companies on the Hong Kong Hang Seng Index. This study adds to the literature as the second study in the field. It is the first comparative study across two time periods of the above‐mentioned data.

To better understand contributing factors and mediating mechanisms related to team dynamics in isolated, confined, and extreme (ICE) environments.

Literature review.

Our primary focus is on cohesion and adaptation – two critical aspects of team performance in ICE environments that have received increased attention in both the literature and funding initiatives. We begin by describing the conditions that define ICE environments and review relevant individual biological, neuropsychiatric, and environmental factors that interact with team dynamics. We then outline a unifying team cohesion framework for long-duration missions and discuss several environmental, operational, organizational, and psychosocial factors that can impact team dynamics. Finally, we end with a discussion of directions for future research and countermeasure development, emphasizing the importance of temporal dynamics, multidisciplinary integration, and novel conceptual frameworks for the inherently mixed work and social setting of long-duration missions in ICE environments.

A better understanding of team dynamics over time can contribute to success in a variety of organizational settings, including space exploration, defense and security, business, education, athletics, and social relationships.

We promote a multidisciplinary approach to team dynamics in ICE environments that incorporates dynamic biological, behavioral, psychological, and organizational factors over time.

This study aims to examine publications of supply chain management (SCM) researchers from across the world and maps the leadership role of authors and institutions based on how prolific they are in publishing and on network measures of centrality while accounting for the quality of the outlets that they publish in. It aims to inform stakeholders on who the leading SCM scholars are, their primary areas of SCM research, their publication profiles and the nature of their networks. It also identifies and informs on the leading SCM research institutions of the world and where leadership in specific areas of SCM research is emerging from.

Based on SCM papers appearing in a set of seven leading journals over the 15-year period of 2001-2015, publication scores and social network analysis measures of total degree centrality and Bonacich power centrality are used to identify the highest ranked agents in SCM research overall, as well as in some specific areas of SCM research. Social network analysis is also used to examine the nature and scope of the networks of the ranked agents and where leadership in SCM research is emerging from.

Authors and institutions from the USA and UK are found to dominate much of the rankings in SCM research both by publication score and social network analysis measures of centrality. In examining the networks of the very top authors and institutions of the world, their networks are found to be more inward-looking (country-centric) than outward-looking (globally dispersed). Further, researchers in Europe and Asia alike are found to exhibit significant continental inclinations in their network formations with researchers in Europe displaying greater propensity to collaborate with their European-based counterparts and researchers in Asia with their Asian-based counterparts. Also, from among the journals, Supply Chain Management: An International Journal is found to exhibit a far more expansive global reach than any of the other journals.

The journal set used in this study, though representative of high-quality SCM research outlets, is not exhaustive of all potential outlets that publish SCM research. Further, the measure of quality that this study assigns to the various publications is based solely on a publication score that accounts for the quality of the journals, as rated by Association of Business Schools that the papers appear in and nothing else.

By informing the community of stakeholders of SCM research about the top-ranked SCM authors, institutions and countries of the world, the nature of their networks, as well as what the primary areas of SCM research of the leading authors in the world are, this research provides stakeholders, including managers, researchers and students, information that is helpful to them not only because of the insights it provides but also for the gauging of potential for embedding themselves in specific networks, engaging in collaborative research with the leading agents or pursuing educational opportunities with them.

This research is the first of its kind to identify and rank the top SCM authors and institutions from across the world using a representative set of seven leading SCM and primary OM journals based on publication scores and social network measures of centrality. The research is also the first of its kind to identify and rank the top authors and institutions within specific areas of SCM research and to identify future research opportunities relating to aspects of collaboration and networking in research endeavors.

A zero-day vulnerability is a complimentary ticket to the attackers for gaining entry into the network. Thus, there is necessity to device appropriate threat detection systems and establish an innovative and safe solution that prevents unauthorised intrusions for defending various components of cybersecurity. We present a survey of recent Intrusion Detection Systems (IDS) in detecting zero-day vulnerabilities based on the following dimensions: types of cyber-attacks, datasets used and kinds of network detection systems.

Purpose: The study focuses on presenting an exhaustive review on the effectiveness of the recent IDS with respect to zero-day vulnerabilities.

Methodology: Systematic exploration was done at the IEEE, Elsevier, Springer, RAID, ESCORICS, Google Scholar, and other relevant platforms of studies published in English between 2015 and 2021 using keywords and combinations of relevant terms.

Findings: It is possible to train IDS for zero-day attacks. The existing IDS have strengths that make them capable of effective detection against zero-day attacks. However, they display certain limitations that reduce their credibility. Novel strategies like deep learning, machine learning, fuzzing technique, runtime verification technique, and Hidden Markov Models can be used to design IDS to detect malicious traffic.

Implication: This paper explored and highlighted the advantages and limitations of existing IDS enabling the selection of best possible IDS to protect the system. Moreover, the comparison between signature-based and anomaly-based IDS exemplifies that one viable approach to accurately detect the zero-day vulnerabilities would be the integration of hybrid mechanism.

The author argues and explains that the indigenous Eastern epistemological frame of yin-yang balancing can be taken as a unique system of thinking toward a meta-perspective. It is not only deeply rooted in the indigenous Eastern culture traditions, but also bears salient global implications, especially in the domain of paradox management. The purpose and contribution of this chapter are twofold: (1) to explain the unique and salient features of yin-yang balancing (the “either/and” system to reframe paradox into duality as partially conflicting and partially complementary, both spatially and temporarily) as compared with the Western logic systems (the “either/or” and “both/or” or “both/and” systems); and (2) to explore the global implications of the “either/and” system for future paradox research, including the three unique themes of overlap between opposites with the “seed” of one opposite inside the other; threshold from the contingent balance between partial separation and partial integration in line with specific contexts through three operating mechanisms, and knot for the special role of third-party to shift paradox from a dyadic level to a triadic and even a multiplex level.

The purpose of this paper is to examine managerial perspectives in both buyer and supplier firms implementing environmental initiatives in their supply chains, and explore the impact of environmental initiatives on buyer-supplier relationships.

A qualitative, grounded theory approach is used as the methodological approach to this research, including 15 in-depth interviews with managers from buyer and supplier firms implementing environmental initiatives in their supply chains to gain multiple perspectives of the buyer-supplier relationships.

The results suggest that implementing environmental initiatives within the supply chain changes the buyer-supplier relationship from transactional to collaborative, shifting from a commodity-focused purchase to a more strategic purchase as environmental initiatives are implemented.

Although both buyer and supplier perspectives were considered, matched dyads were not used; researchers should continue to provide a holistic perspective of the phenomenon with dyadic data. Additionally, the use of a qualitative research approach suggests a lack of generalizability of results, and therefore researchers should further test the propositions.

Implementing environmental initiatives within the supply chain may require different approaches to supply management and development for long-term success. Suppliers should recognize that the capability to implement environmental initiatives with their customers is a differentiator. The nuances involved in managing the implementation of environmental initiatives between firms can be better managed by collaboratively developing metrics specifically related to the environment.

Previous research in environmental supply chain management has examined drivers and barriers of implementing environmental initiatives with suppliers, but fails to address the relationship dynamics involved when implementing environmental initiatives between organizations. This research begins to fill that gap.

The exponential growth of digital technologies and their increased importance in both organizational and everyday life poses new challenges to paradox research within management studies. Management scholars taking a paradoxical lens have predominantly focused on social paradoxes within the confines of the organization. Technological change has often been treated as an exogenous force bringing previously latent tensions to the fore. Such newly salient paradoxes are viewed as instigating managerial sensemaking and exploration of strategic responses that will re-establish equilibrium. Our investigation of how digital innovations disrupted London taxiwork and global music distribution shows something different. The paradoxical tensions raised by emerging digital technologies inevitably play out at industry and societal levels. Concomitant changes in boundaries, categories, and potentials for action that shape and channel ongoing industry transformation call for organizational responses and adaptation. Critically, such tensions must be interpreted within the context of industry arrangements absent a centrally controlling actor. Rather than episodes of exogenous change, the nature of the digital, along with interactions across multiple sources of agency, continually surface complex dynamic and systemic tensions within and across industries. Our findings highlight the importance of explicitly accounting for the inter-relatedness and mutual dependence of the social and technical elements of change. As digital innovation expands and starts to impact all aspects of human experience it is critical for management scholars to reflect how the paradoxical perspective can be expanded to better understand these contemporary large-scale changes.
