Reputation-Based Trust Approaches in Named Data Networking

Information-Centric Networking (ICN) has arisen as an architectural solution that responds to the needs of today’s overloaded Internet, departing from the traditional host-centric access paradigm. In this paper we focus on Named Data Networking (NDN), the most prominent ICN architecture. In the NDN framework, disseminated content is at the core of the design and providing trusted content is essential. In this paper, we provide an overview of reputation-based trust approaches, present their design trade-offs and argue that these approaches can consolidate NDN trust and security by working complementary to the existing credential-based schemes. Finally, we discuss future research directions and challenges.

Purpose The purpose of this study is to critically examine the scholarly articles associated Murali Sambasivan with the diverse aspects of supply chain agility (SCA). The review highlights research insights, existing gaps and future research directions that can help academicians and practitioners gain a comprehensive understanding of SCA. Design/methodology/approach The present study has adopted author co-citation analysis as the research methodology, with a view to thoroughly investigating the good-quality articles related to SCA that have been published over a period of 22 years (1999-2020). In this study, 126 research papers on SCA – featuring diverse aspects of agility – from various reputed journals have been examined, analysed and assimilated. Findings The salient findings of this research are, namely, agility is different from other similar concepts, such as flexibility, leanness, adaptability and resilience; of the 13 dimensions of agility discussed in the literature, the prominent ones are quickness, responsiveness, competency and flexibility; literature related to SCA can be categorised as related to modelling the enablers, agility assessment, agility implementation, leagility and agility maximisation. This research proposes a more practical definition and framework for SCA. The probable areas for future research are, namely, impediments to agility, effective approaches to agility assessment, cost-benefit trade-offs to be considered whilst implementing agility, empirical research to validate the framework and SCA in the domain of healthcare and disaster relief supply chains. Practical implications This paper provides substantial insights to practitioners who primarily focus on measuring and implementing agility in the supply chain. The findings of this study will help the supply chain manager gain a better idea about how to become competitive in today’s dynamic and turbulent business environment. Originality/value The originality of this study is in: comprehensively identifying the various issues related to SCA, such as related concepts, definitions, dimensions and different categories of studies covered in literature, proposing a new definition and framework for SCA and identifying potential areas for future research, to provide deeper insights into the subject and highlight areas for future research.

Different Levels

Urbanization is taking place at an unprecedented pace and scale in China, India, and many other emerging economies. This will have profound impacts on the world economy and environment. This review provides a critical assessment of the current understanding of the intertwined relationships between agglomeration, economic growth, and environmental quality. We start by providing a brief overview of the extensive literature on the drivers of agglomeration and its economic impact. We then discuss the opposing views on the environmental impact of agglomeration and illustrate the trade-offs involved when choosing among different levels and forms of agglomeration. Finally, we discuss challenges for environmental management in a rapidly urbanizing economy and some lessons learned from history and experiences of urban development and their policy implications. The review concludes with a discussion of key knowledge gaps and future research directions.

Over Time

This paper provides a bibliometric analysis of the digital sustainability literature from four angles: economics, management/business, information systems/IT, and sociology/communication. The core contribution is to map the development of the literature in digital sustainability over time and across various clusters. Through VOSviewer analysis, we identify the main keywords used by the literature; the countries from which most of the literature is emerging; the most influential authors working in the field; and, their impacts by observing their citations and networks. Moreover, through CitNetExplorer analysis, we track the development of the field over time, i.e., identify key publications and divide those into clusters. The analysis finds a much more developed coverage of digital sustainability in the scholarship of management/business and therefore reveals a clear need for greater exploration of the sociological and economic aspects of digital sustainability. We argue that more robust collaboration patterns should be established among all four considered disciplines to achieve progress in digital sustainability. We envisage that digital sustainability as a field of study will mature as publications and ideas will become consolidated. Such integration strengthens the evolution of the field and topics across all four considered disciplines.

Core Construct

This chapter first provides an overview of both the historical and contemporary positive approaches to the workplace. More specific attention is then given to the meaning and domain of positive organizational behavior, or POB, and psychological capital, or PsyCap. Our definition of POB includes positive psychological resources that can be validly measured and developed and that have performance impact. The constructs that have been determined so far to best meet these criteria are hope, efficacy, resilience, and optimism. When combined, it has been demonstrated that they form the core construct of what we term PsyCap. Multiple measures of PsyCap have been validated. An increasing number of review articles and research studies clearly indicates that PsyCap can be developed and has performance impact. The chapter concludes with important future research directions that can help better understand and build positive workplaces to meet current and looming challenges.
