The term context has been utilized in scholarship to reference a variety of phenomena and settings across the communication discipline and field of group communication. This chapter examines journal articles and book chapters to explore how the word context is used in group communication scholarship. The hope is that by considering how context is used in academic writing, scholars may find ways to better specify the influences and features of group communication studies. If not, the term context may continue to be used in reference to almost anything, which means the word may be unhelpful or prevent meaningful conversations across journal articles.

Smart contracts are self-executing computer programmes that have the potential to be used in several applications instead of traditional written contracts. With the recent rise of smart systems (e.g. Internet of things) and digital platforms (e.g. blockchain), smart contracts are gaining high interest in both business and academia. In this work, a framework for smart contracts was proposed with using reputation as the system currency, and conducts currency mining through fulfilling the physical commitments that are agreed upon.

A game theory model is developed to represent the proposed system, and then a system dynamics simulator is used to check the response of the blockchain with different sizes.

The numerical results showed that the proposed system could identify the takeover attacks and protect the blockchain from being controlled by an outsider. Another important finding is that careful setting of the maximum currency amount can improve the scalability of the blockchain and prevent the currency inflation.

This work is proposed as a conceptual framework for supply chain 4.0. Future work will be dedicated to implement and experiment the proposed framework for other characteristics that may be encountered in the context of supply chain 4.0, such as different suppliers' tiers, different customer typologies and smart logistics applications, which may reveal other challenges and provide additional interesting insights.

By using the proposed framework, smart contracts and blockchains can be implemented to handle many issues in the context of operations and supply chain 4.0, especially in times of turbulence such as the COVID-19 global pandemic crisis.

This work emphasizes that smart contracts are not too smart to be applied in the context of supply chain 4.0. The proposed framework of smart contracts is expected to serve supply chain 4.0 by automating the knowledge work and enabling scenario planning through the game theory model. It will also improve online transparency and order processing in real-time through secured multitier connectivity. This can be applied in global supply chain functions backed with digitization, notably during the time of the pandemic, in which e-commerce and online shopping have changed the rules of the game.

This study investigates the impact of the COVID-19 pandemic on the types and sources of information sought by older adults along with their motivations in the Midwestern United States.

Interviews were conducted with 30 older adults residing in rural communities around the Midwestern United States during late-summer (July/August) 2020, using a protocol based on Dervin's Sense-Making Methodology. The resulting data was analyzed using standard content analysis procedures, guided by the theoretical frameworks based on Dervin's Sense-Making and Williamson's Ecological Model of Information Behavior. Implications of COVID-19 for the normative behaviors described in these models are discussed.

Findings show that older adults were concerned primarily with health and political information during this period, but that this information was not necessarily sought only to address an informational need, but also to satisfy the need to maintain social and emotional connections in coping with isolation and loneliness. Sources of information that allowed for social interaction with people were favored. Wider personal networks (community members) were strained by the social distancing measures and closures. These findings have theoretical and practical implications for considering the impact of social restrictions on information seeking behaviors of older adults in a time of crisis.

This study is the first, known to the authors, that applied the two adopted theoretical frameworks to explore information seeking behaviors of older adults during the COVID-19 pandemic.
