Global supply chains are facing many changes after the COVID-19 pandemic. This change impacts the way each supply chain measures its key performance indicators and determinants for its competitiveness. Aquaculture supply chains (SCA) play an essential role in global trading and fluctuated significantly during the COVID-19 pandemic when many aquaculture supply chains from emerging countries faced disruption. Therefore, after the COVID-19 pandemic, these supply chains have changed their measures and determinants to improve global competitiveness. This paper examines the change in this measure and determinants of the aquaculture supply chain in Vietnam, one of the world’s top 10 biggest exporting countries of aquaculture products. The paper reviews the list of measures and determinants of the aquaculture supply chain before and after the COVID-19 pandemic from the literature. It forms the framework under the shade of Resource-Based View theory. A total of 38 interviews with managers and CEOs of 36 enterprises and two government agencies in the aquaculture supply chain in Vietnam were conducted to explore the strategic changes in the measures of determinants to cope with the new circumstances of current global trade. The findings contribute to enriching the theory in the new VUCA (volatility, uncertainty, complexity, and ambiguity) business environment after the COVID-19 pandemic. In this context, SCA should be defined by supply chain virtues that are associated with the new business environment, such as SC resilience, SC sustainability, SC reliability, SC integration, etc. This finding implies a new horizon for RBV applications, highlighting their adaptability. It suggests that the measures defining competitive advantage in the new business environment should extend beyond the traditional tangible and intangible resources under business certainty. They should also encompass those that differentiate the firms and their supply chain during business turbulence.

Online consumer ratings play a crucial role in determining a product's long-term success. This study examines the direct impact of consumer technology frustration and consumer passion on app ratings and evaluations over time. Beyond these direct effects, we propose that consumer passion moderates the relationship between technology frustration and evaluations-specifically, passion amplifies the negative impact of frustration, making a double-edged sword. Using data from the Google Play Store, we tracked the top 20,000 Android apps over three months (September 29, 2023-January 1, 2024), constructing a panel dataset with 11,568 panels and 13,810 observations. Our disaggregated analysis-considering download volume, app age, price, and publisher rating-confirms the hypothesized effects. Remarkably, established apps and publishers are particularly vulnerable to the intensified negative substitution effect. Our findings suggest that new app developers should prioritize a functional, intuitive platform and enhance it over time to foster consumer passion. Meanwhile, established apps must actively minimize technological frustration, as passionate users' negative experiences can significantly impact ratings and future downloads.

In recent years, big data analytics has become widely applied in cybersecurity, leading to the novel approach of big data cybersecurity analytics. While some organizations have been adopting this new approach in tackling cybercrime, there are limited guidelines to which companies can refer. Therefore, the renowned maturity model concept, which offers a systematic approach for an organization to measure and improve its maturity level, is applied in this study. On the basis of a comprehensive literature review, this chapter proposes a maturity framework for big data cybersecurity analytics. This synthesized comprehensive maturity framework comprises seven dimensions across five stage levels—namely organization, human, infrastructure, data management, analytics application, governance, and security dimensions. Knowing which dimensions need to be improved and which pathway to follow ensures the successful implementation of big data cybersecurity analytics within organizations.

Purpose: This article aims to investigate the role of supply chain collaboration as the mediator of the relationship between organisational culture and competitive edge based on differentiation in the context of garment firms in Vietnam. Design/methodology/approach: Underpinned by the relational view (RV) and organisational culture (OC) theories, a conceptual framework on the interrelationships between OC, differentiation competitive advantage and supply chain collaboration was proposed. This study collected data through a survey of 192 managers working in garment companies in Vietnam. Factor analysis was performed to assess the internal consistency of the attribute combination in SPSS. Then, the mediation effects of the constructs were analysed using the bootstrapping method. Findings: The results indicate that the internal collaboration aspect of supply chain collaboration mediates the relationship between the group culture type of OC, and differentiation-based competitive advantage, with a similar effect observed for the development culture type. However, the external collaboration aspect of supply chain collaboration does not significantly mediate the relationship between these two OC types and differentiation-based competitive advantage. Originality/value: This study contributes to the existing body of knowledge in several ways. Firstly, while previous studies investigated the importance of OC in operational performance, this research found that OC also positively impacts differentiation-based competitive advantage. Besides, it is perhaps among the first to rigorously examine both external and internal supply chain collaboration as a mediator between OC and competitive edge based on differentiating features in Vietnam's garment industry, offering an expanded understanding of the role of this construct for both supply chain management literature and practice. Moreover, it extends the application of RV and OC theories to a new research context.
