Circular economy and big data analytics: A stakeholder perspective

Abstract: This study evaluates the transshipment productivity of circular waste in six Polish seaports between 2013 and 2022 using the Malmquist Data Envelopment Analysis (DEA) method. The model is output-oriented and incorporates transshipped waste volumes as outputs, while inputs include quay length, maximum permissible draft, and maximum ship length. The results show that Gdynia achieved the highest productivity growth (+9.9%), followed by Darłowo (+2.8%) and Szczecin (+1%). In contrast, Świnoujście and Kołobrzeg experienced notable declines. Gdynia and Szczecin exhibited constant scale efficiency, while others suffered from scale disadvantages. Overall, total productivity increased slightly (+0.3%) over the decade, primarily due to technological change. Peaks in productivity in 2015 and 2020 correlated with significant technological improvements. These findings have practical policy implications: port authorities can benchmark their operations, identify inefficiencies, and tailor infrastructure investments to optimise the handling of circular waste. The results suggest that smaller, secondary ports – often overlooked in port research - can play a strategic role in circular supply chains if supported by proper planning and targeted modernisation. The application of Malmquist DEA in this novel cargo category and port group demonstrates the model’s potential for sustainable performance evaluation in complex logistics environments.

TL;DR: In this paper , the authors examined the effects of data analytics capabilities on organizational ambidexterity and the paradoxical tensions between exploration and exploitation in the Malaysian banking sector, and found that BDAC positively influences the two contradictory aspects of organizational ambidesterity (i.e., explorative dynamic capabilities and exploitative dynamic capabilities).

Abstract: This study explores the impact of digital maturity on the environmental, social, and governance (ESG) performance of Turkish companies listed on Borsa Istanbul. The analysis is based on a sample of 49 non-financial firms included in the BIST 100 Index, covering the period of 2016-2022. A digital maturity index is constructed using a text mining approach to quantify the frequency of digital-related terms in the firm’s annual reports. Panel data analysis is employed to investigate the relationship between digital maturity and ESG performance. The findings indicate that digital maturity has a significant inverse U-shaped effect on social performance, an insignificant inverse U-shaped effect on environmental performance, and an insignificant U-shaped effect on corporate governance performance. The results suggest that moderate levels of digitalization enhance social performance, whereas excessive digitalization may have an adverse effect.

TL;DR: In this article, the authors examined the link between firm resources and sustained competitive advantage and analyzed the potential of several firm resources for generating sustained competitive advantages, including value, rareness, imitability, and substitutability.

TL;DR: In this paper, the authors describe the process of inducting theory using case studies from specifying the research questions to reaching closure, which is a process similar to hypothesis-testing research.

TL;DR: In this article, a firm is considered to have a sustained competitive advantage when it is implementing a value creating strategy that no competitor is implementing and when these competitors are unable to duplicate the benefits of this strategy.

TL;DR: In this paper, the authors define a leadership event as a perceived segment of action whose meaning is created by the interactions of actors involved in producing it, and present a set of innovative methods for capturing and analyzing these contextually driven processes.
