The internationalization of Chinese multinational enterprises (MNEs) has triggered a rapid rise in research on their knowledge management practices. However, this literature lacks a coherent theory to explain variation in Chinese MNEs’ knowledge management strategies in and over time. In particular, we still lack an understanding of how firms navigate the unique tension between a home-country state-as-strategist and the market-led logic of global competition. To address this theoretical gap, this paper draws on a systematic review of 150 articles to develop a state-market interplay framework for the strategic knowledge management of Chinese MNEs. Our framework explains how the relationship between state-led and market-led logics generates three distinct strategic modes, each with a corresponding dominant knowledge management strategy: (1) Subordinated Interplay emphasizing knowledge acquisition; (2) Conflicting Interplay focused on knowledge transfer; and (3) Integrated Interplay concentrating on global knowledge creation. We also identify firm-level capabilities and external and internal catalysts that influence transitions between modes. The study contributes to International Business theory and the knowledge-based view by offering a typology of state–market interplay in state-capitalist economies and by explaining the institutional contingencies of firms’ knowledge strategies. We conclude by outlining avenues for future research.

Organisational self-identification (OSI) refers to a shared understanding of an organisation’s collective identity. This identity shapes the organisational culture, employee engagement and commitment, and overall performance. While policy documents define rules and interactions, both their substance and tone reinforce or diminish the OSI. However, traditional policy reviews often overlook whether the language and tone of these documents truly reflect organisational values. In this study, we introduce an AI-powered sentiment analysis framework that offers a novel and systematic approach to evaluate OSI alignment in policy texts. Our OSI Sentiment Analyser combines a customised lexicon with rule-based scoring to identify and classify sentiments at multiple levels while ensuring transparency, explainability, and respect for privacy. The analyser was validated across 78 public policies (where it achieved over 90 % agreement with expert judgement) and further tested in two NHS hospital trusts as case studies. The proposed framework not only supports evidence-based policy refinement but also fosters inclusive and value-driven communication. Its modular design promises broad application, from employee surveys to strategic organisational messaging. Accordingly, it advances both theory and practice in organisational identity analytics.

This study examines how generative artificial intelligence (GenAI) adoption announcements affect firm value in the tourism industry, focusing on online travel agencies (OTAs), hotel companies, and major technology firms. Drawing on signaling theory, two-sided market theory, competitive dynamics, and disruption theory, we analyze GenAI-related announcements made between November 2022 and October 2024 using an event study methodology. The findings reveal that market responses vary depending on the source of the announcement and the type of firm affected. While GenAI announcements from OTAs and hotels generate negative spillover effects for other tourism firms, OTAs experience positive responses to their own and hotel announcements. In contrast, announcements from tech firms trigger negative reactions across OTAs and hotels, suggesting concerns about platform dependency and value displacement. These results highlight the strategic complexity of GenAI signaling and its implications for firm positioning in platform-based industries.

This paper proposes that as climate collapse accelerates, the normative horizons underpinning critical accounting scholarship – reform, transformation and hope – are increasingly out of step with planetary and political realities. As a result, it argues for a reorientation of critical accounting scholarship in light of systemic breakdown. Drawing on recent interdisciplinary literature in environmental collapse, decolonial theory and climate activism, including those from the Global South and Indigenous perspectives, the paper proposes a collapse-aware framework to rethink the purpose of critique. Through this lens, existing concerns in the accounting literature – for example, those focused on institutional reform/critique or the construction of alternatives to prevailing dominant systems of power – appear in a different light. Rather than being underpinned by temporal assumptions that presume a still-recoverable future, a collapse-aware perspective reframes the purpose of critique, not as a pathway to systemic change but as a form of ethical engagement amidst unravelling. The paper outlines a set of practices for collapse-aware scholarship, arguing that if the task is no longer to save the system, we must remain accountable within its disintegration. This is not a call for despair or disengagement but a proposal to inhabit our scholarship differently: to stay with the trouble, hold space for grief, amplify refusal and act in solidarity with those bearing the weight of collapse. In doing so, the paper offers a renewed vision of critical accounting – one not grounded in hope for transformation but in responsibility to the world as it is.

The ongoing electrification of the transport sector, driven by the numerous advantages of electric vehicles (EVs), introduces new challenges related to charging logistics, particularly due to long charging durations and uncertain conditions, posing significant negative impacts on grid stability and user satisfaction. While existing literature on EV charging scheduling often assumes deterministic charging durations, real-world conditions introduce randomness due to uncontrollable factors such as battery state-of-charge (SoC), fluctuating grid demand, and ambient temperature. In this paper, we address the Electric Vehicle Charging Scheduling Problem (EVCSP) under uncertain charging durations. First, we introduce a novel, flexible multi-objective scheduling model operating on a continuous time horizon, considering stochastic charging durations and incorporating controlled preemptions during charging, where the non-preemptive mode is a particular case. Then, we prove that finding a feasible assignment of EVs to chargers is strongly NP-hard under this uncertainty, even assuming identical chargers. Our model accounts for realistic constraints, including heterogeneous charger power levels and vehicle-charger compatibility, aiming to minimize the conditional expected values of grid overload and total tardiness, while also minimizing the undelivered energy to users. Given the problem’s computational complexity, we adapt four evolutionary algorithms (EAs), namely, extensions of the Non-Dominated Sorting Genetic Algorithm (NSGA), namely NSGA-II and NSGA-III, alongside other state-of-the-art multi-objective metaheuristics, including the Multi-Objective Cuckoo Search (MOCS) algorithm, and the Multi-Objective Grey Wolf Optimizer (MOGWO) by defining problem-specific operators to explore the search space and efficiently approximate the optimal Pareto front. Assuming lognormally distributed charging durations, we conducted a comparative experimental analysis on real-world data to evaluate the four methods and revealed that MOCS algorithm outperforms the other competitors.

The growing global emphasis on research excellence has heightened academic attention to effective research performance management. Scientific collaboration is a crucial driver for the formation of high-impact research. However, its mechanism of action remains incompletely understood, particularly with respect to the effect of the collaboration among supervisors on the academic impact of dissertations in the context of co-supervision of graduate students. Based on the three-dimensional framework theory of social capital, this paper develops a measurement indicator system for team social capital within dissertations. Using a sample of 16,567 master's and doctoral dissertations in the field of statistics from China during 2000 to 2020, it empirically examines the mechanisms through which social capital influences citation-based performance in the context of co-supervision. The results indicate that the structural, cognitive, and relational dimensions of social capital all significantly affect citation counts. Specifically, cognitive diversity exhibits a positive effect, the strength of co-supervision relationships shows a negative effect, and structural capital demonstrates a U-shaped relationship. Furthermore, the difference in supervisors' seniority significantly moderates the relationship between structural capital and citation-based performance, whereas the moderating effects of supervisor team size and cognitive difference are not supported. This study offers empirical insights for optimizing co-supervision practices, enhancing the citation impact of dissertations, and improving graduate students training.

Multi-stage stochastic optimization is a well-known quantitative tool applied in a wide variety of decision-making problems. In this article, we focus on generalized flood risk management problems with Fréchet distributions used to describe the uncertainty. Theoretical solutions of such problems can be found explicitly only in exceptional cases due to their variational form and interdependency of uncertainty in time, e.g., due to cascading impacts of extreme floods. Nevertheless, numerical methods based on Monte Carlo sampling are inaccurate, as the Law of Large Numbers must hold for sufficient approximation quality. To overcome this shortcoming, we introduce an approximation scheme that computes and groups together optimal quantizers of Fréchet distributions. The groups are distinguished by a particular risk threshold and differentiate between higher- and lower-impact floods. We consider optimality of quantization methods in the sense of the minimal Kantorovich–Wasserstein distance. Depending on the group, to which a quantizer belongs, and on the form of the optimization problem, we propose two dynamic programming schemes: with accelerated dynamics and with non-accelerated dynamics. For the accelerated method, the groups of quantizers are used to cut scenario trees and guarantee optimality gaps close to zero. For the non-accelerated method, the probabilities of quantizers are used to weight value functions and bound the approximation error with convergence guarantees. Global solution is guaranteed under convexity and monotonicity conditions on the value functions. Considering cases with and without circular economy indicators able to reduce emissions, we apply the methods we developed to the governmental budget allocation problem under flood risk in Austria.

The increasing frequency and severity of global disruptions have underscored the structural vulnerabilities of conventional supply chains, particularly those optimized solely for efficiency. This study addresses a critical gap at the intersection of omnichannel logistics and circular economy integration by proposing a unified, resilience-oriented optimization model. The integration of these two paradigms is essential: while omnichannel networks inherently involve complex bidirectional flows, circular economy strategies provide built-in redundancy and resource recirculation capabilities. However, existing literature largely overlooks their combined potential for proactive disruption preparedness. To bridge this gap, we develop a mathematical model that simultaneously optimizes forward logistics (including facility siting, inventory allocation, cross-docking, and multimodal transport) and reverse flows (returns handling, material recovery, and recycling). Circular economy decisions are modeled as endogenous variables that dynamically adapt to disruption scenarios, allowing real-time reconfiguration of fulfillment strategies across online, in-store, and humanitarian channels. The model is validated through a real-world application in a national-scale canned food supply network. Results suggest the model maintains performance across varying disruption intensities and operational scales, revealing key trade-offs between profit efficiency, environmental impact, and service responsiveness. The findings highlight that resilience is most effectively achieved through anticipatory strategies such as capacity flexibility and fulfillment agility, rather than through reactive or compliance-driven measures alone. This study offers a scalable decision-support tool for practitioners and policymakers seeking to design sustainable, adaptive, and disruption-resilient omnichannel supply chains.

Despite the growing adoption of generative artificial intelligence (GenAI) in online travel agencies (OTAs), its impact on tourists' review behavior remains poorly understood. Within the information overload framework, this study offers a novel dual-path theoretical framework that integrates both generalized reciprocity and suppressed social loafing mechanisms. Using a multi-method design comprising a natural experiment with regression discontinuity design and controlled online experiments across three studies, we investigated how GenAI-powered review summaries shape tourists' review intention. Our findings reveal that exposure to GenAI summaries enhances review intention through generalized reciprocity. By alleviating information overload and reducing perceived processing effort, these summaries motivate tourists to reciprocate by composing their own reviews, thereby ''paying forward'' the benefits received, rather than triggering free-riding that would diminish review intention. These findings advance theoretical knowledge of information processing, GenAI's influence on tourists' decision-making, and tourists' review behavior, while providing actionable insights for OTAs and hospitality management.

Within the information overload framework, this study offers a novel dual-path theoretical framework that integrates both generalized reciprocity and suppressed social loafing mechanisms. Using a multi-method design comprising a natural experiment with regression discontinuity design and controlled online experiments across three studies, we investigated how GenAI-powered review summaries shape tourists' review intention. Our findings reveal that exposure to GenAI summaries enhances review intention through generalized reciprocity.
