This study explores the use of augmented reality smart glasses (ARSGs) by physicians and their adoption of these products in the Turkish medical industry. Google Glass was used as a demonstrative example for the introduction of ARSGs. We proposed an exploratory model based on the technology acceptance model by Davis. Exogenous factors in the model were defined by performing semi-structured in-depth interviews, along with the use of an expert panel in addition to the technology adoption literature. The framework was tested by means of a field study, data was collected via an Internet survey, and path analysis was used. The results indicate that there were a number of factors to be considered in order to understand ARSG adoption by physicians. Usefulness was influenced by ease of use, compatibility, ease of reminding, and speech recognition, while ease of use was affected by ease of learning, ease of medical education, external influence, and privacy. Privacy was the only negative factor that reduced the perceived ease of use, and was found to indirectly create a negative attitude. Compatibility emerged as the most significant external factor for usefulness. Developers of ARSGs should pay attention to healthcare-specific requirements for improved utilization and more extensive adoption of ARSGs in healthcare settings. In particular, they should focus on how to increase the compatibility of ARSGs. Further research needs to be conducted to explain the adoption intention of physicians.

PurposeThe authors posit that one of the key enablers of the circular economy will be the digital transformation – in other words, “digitalization.” In this study, the authors examine and visualize the interaction of the circular economy and digitalization by using scientific publications. They explore possible synergies and future research avenues at this junction.Design/methodology/approachThe authors first apply bibliometrics to explore and visualize the relationships between the circular economy and digitalization in the academic literature. Following the clustering of topics, they define key emerging factors for each cluster. Based on this analysis, they suggest future research avenues.FindingsThe authors find that there are four main clusters at the junction of circular economy and digitalization, including (1) sharing economy, (2) additive manufacturing, (3) business models and (4) industrial ecology and remanufacturing. They then dig deeper into these topics to better understand what factors would shape the future of the clusters. They conclude that sharing economy perspective and additive manufacturing may be enhanced by regulation-based and behavioral change-based approaches. Circular business models should be developed to maintain circularity in industry. Finally, digital manufacturing should be implemented within the framework of industrial ecology and remanufacturing principles to increase efficiency, productivity and traceability in the circular economy.Originality/valueDigitalization offers significant potentials toward breakthrough sustainability by creating a circular economy. Hence, understanding the relationship between circular economy and digitalization is important to achieve sustainable development goals.

Purpose -In this study, some of the internal and external determinants of innovation for Turkish companies are examined. The purpose of this paper is to determine which factors significantly influence innovativeness of Turkish companies. Design/methodology/approach -The study begins with literature research. The knowledge gained from literature is used to develop a research model, which displays internal and external determinants of innovation and innovation types as product and process innovations. In order to test the model, the data of "Business Environment and Enterprise Performance Survey", provided by the World Bank, are used. The data are collected from 1,152 Turkish companies in 2008. Some statistical tests are conducted to determine significant relations between the determinants of innovation and innovation types. Finally, results are discussed in the light of previous literature. Findings -The authors' results provide clues that the companies involved in product innovation activities mostly perform process innovations. There is also a group of companies which invest in capabilities, but are not involved in any of the innovative activities. R&D activities, licensed technology usage, formal training programs, and experience of managers are significant internal factors, although the investments accomplished are not significant. International relations are an outstanding external factor for Turkish companies.Research limitations/implications -The data used in this study come from secondary source data, and it is not aimed at exploring innovation-related issues. Also, this study does not aim to rank influencing factors for Turkish companies. Thus, it is not possible to reach a conclusion that compares internal and external factors. Originality/value -This is a pioneer study that deals with internal and external influencing factors of both product and process innovations for Turkish companies.

Purpose The COVID-19 pandemic has disrupted the supply chains, and this brought researchers and practitioners to think about more on circular supply chains (CSC). The CSC concept has been discussed in the literature more than a decade. This study aims to find out the theoretical roots of CSC by analyzing scholarly articles in literature. Design/methodology/approach This paper uses document cocitation analysis for reaching this aim. After retrieving data from Web of Science database, this paper explores data set by considering used references of these publications and clusters them based on their title terms and visualizes them by using cosine similarity index. Findings This paper concludes that CSC is mainly discussed along with sustainability, sustainable supply chains and green supply chains, where the focus is integrating circular economy principles to supply chain management (SCM). On the other hand, although resiliency is an essential characteristic of SCM, contribution of CSC to supply chain resilience is neglected in the literature. Research limitations/implications CSC will gain importance in near future to increase national/firm productivity, and findings of this paper will give researchers insights for furthering their studies. Social implications To avoid supply chain and market collapse caused by natural disruptions, supply chain resilience is of paramount importance. According to the findings of this paper, the authors believe that business resilience in COVID-19-restricted environment may have exit point by using circular perspective. Originality/value The importance of CSC has increased due to the disruptions caused by the COVID-19 pandemic. Therefore, this unique study was undertaken to investigate the evolution of this crucial topic with evidence from the literature through a cocitation analysis.
