Abstract
Purpose
The quality of the unstructured mesh has a considerable impact on the stability and accuracy of aerodynamic simulation in computational fluid dynamics (CFD). Typically, engineers spend a significant portion of their time on mesh quality evaluation to ensure a valid, high-quality mesh. The extensive manual interaction and a priori knowledge required to undertake an accurate and timely evaluation process have become a bottleneck in the idealized efficient CFD workflow. This paper aims to introduce a neural network-based quality evaluation approach for unstructured meshes to enable higher efficiency and the level of automation.
Design/methodology/approach
The paper investigates the capability of deep neural networks for the quality evaluation of unstructured meshes. For training the network, we build a training dataset for mesh quality learning algorithms. The dataset contains a rich variety of unstructured aircraft meshes with different mesh sizes, densities, cell distribution, growth ratios and cell numbers to ensure its diversity and availability. We also design a neural network, AircraftNet, to learn the effect of mesh quality on the convergent properties of the numerical solutions. The proposed network directly manipulates raw point data in mesh source files rather than passing it to an intermediate data representation. During training, AircraftNet extracts non-linear quality features from high-dimensional data spaces and then automatically predicts the overall quality of the input unstructured mesh.
Findings
The paper provides a series of experimental results on GPUs. It shows that AircraftNet is able to effectively analyze the quality-related features like mesh density and distribution from the extracted features and achieve high prediction accuracy on the proposed dataset with even a small number of training runs.
Research limitations/implications
Because of the limited training dataset, the research results may lack generalizability. Therefore, researchers are encouraged to test the proposed propositions further.
Originality/value
The paper publishes a benchmarking dataset for mesh quality learning algorithms and designs a novel neural network approach for unstructured mesh quality evaluation.

Abstract
Purpose
In this research, we explore the adverse impact of foreign ownership on operational security, a critical operational implication of the liability of foreignness (LOF).
Design/methodology/approach
The empirical analysis is based on a multi-country dataset from the World Bank Enterprises Survey, which contains detailed firm-level information from over 8,902 firms in 82 emerging market countries. We perform a series of robustness checks to further confirm our findings.
Findings
We find that a high ratio of foreign ownership is associated with an increased likelihood of security breaches and higher security costs. Our results also indicate that high levels of host countries’ institutional quality and firms’ local embeddedness can mitigate such vulnerability in operational security.
Originality/value
This study is one of the first to uncover the critical operational implication of the LOF, indicating that a high ratio of foreign ownership exposes firms to operational security challenges.

Abstract
Purpose
Organizations are partly responsible for the pollution in the world and are expected to contribute towards curbing climate change. Despite the growing importance of the environmental aspect of corporate social responsibility (CSR), i.e. corporate environmental responsibility (CER), current literature focuses more on its antecedents and outcomes rather than drilling deeper into the essential elements of the concept. This has resulted in conceptual confusion as researchers use different aspects to define, understand and measure CER. Hence, this study aims to identify the critical dimensions of CER from a practitioner’s point of view.
Design/methodology/approach
Twenty-eight semi-structured interviews were conducted with senior sustainability professionals across top Bombay Stock Exchange-indexed organizations in India. Manual content analysis and the Gioia method were used to arrive at the findings.
Findings
The critical components of CER are as follows: encompassing environmental responsibility mindset; optimized resource consumption; neutral water, energy and air status; multi-level environmental responsibility approach and targets; compliance, disclosure, reporting and policy formation; and green supply chain.
Originality/value
Our research introduces a comprehensive framework of dimensions to study, measure and represent CER, addressing a critical gap in the current literature. The authors identify and propose novel dimensions, such as the CER mindset and a multi-level approach, which are essential for a holistic understanding of CER. These dimensions, presently absent in academic definitions, render existing research based on those definitions incomplete. Integrating these new dimensions will significantly enhance the rigor and relevance of CER studies, offering a more robust foundation for future research and practical application.

Abstract
Purpose
The primary objective of the study is to enhance the accuracy and efficiency of assessing the proliferation index in cancer cells, specifically focusing on the role of Ki-67. The purpose is to address the limitations of traditional visual assessments conducted by pathologists by integrating AI technologies, particularly deep learning. By accurately computing the percentage of Ki-67-labeled cells, the research aims to streamline the diagnostic process, reduce subjectivity and contribute to the advancement of diagnostic precision in pathological anatomy.
Design/methodology/approach
The research employs a methodological approach that integrates Ki-67, a non-histone nuclear protein, as a vital biomarker for assessing the proliferative status of cancer cells. Given the challenges associated with traditional visual assessments by pathologists, including inter- and intra-observer variability and time-consuming efforts, the study adopts a novel methodology leveraging artificial intelligence (AI) solutions. Deep learning is applied to precisely calculate the percentage of Ki-67-labeled cells.

Abstract
Purpose
The purpose of this study is to examine the mechanisms of absorptive capacity (ACAP) in the specific context of digital product development teams. More precisely, it explores the process of internalizing and utilizing external knowledge from sources outside the team to promote the development of innovative ambidexterity.
Design/methodology/approach
The study employs the ACAP framework and directs specific attention to the concept of knowledge assimilation, encompassing comprehension, documentation and dissemination. Seventy-five employees of one of Indonesia’s largest commercial banks were surveyed about two initiatives they participated in. To this end, 12 research hypotheses are formulated, tested and analyzed using structural equation modeling.
Findings
Knowledge comprehension, documentation and dissemination are found to mediate between knowledge acquisition and knowledge exploitation. At the same time, the relationship between knowledge acquisition and knowledge transformation is mediated by knowledge comprehension and dissemination, but not documentation. The authors also found that knowledge transformation positively mediates between knowledge comprehension and dissemination on the one hand and ambidexterity on the other hand. Importantly, knowledge exploitation negatively mediates between knowledge comprehension and documentation on the one hand and ambidexterity on the other hand.
Originality/value
This study contributes to the existing body of knowledge by offering nuanced insights into the interplay of knowledge assimilation processes within ACAP, particularly in the context of digital product development. The identification of mediating factors and their impacts on ambidexterity provides valuable implications for both theory and practice in this domain.

Abstract
Purpose
The issue of excessive carbon emissions continues to be a critical global challenge. As a prominent mode of transportation for long-distance travel, aircraft is widely acknowledged as a significant source of these emissions. Carbon offset initiatives function as ecological measures, helping to reduce the negative environmental impact. This study aims to explore how benefit appeals (BA) within the aviation industry impact tourists’ carbon offset payment intentions (COPIt).
Design/methodology/approach
In Studies 1 and 2, scenario-based experiments were conducted to explore how goal framing (GF) and (BA) interact to influence COPIt. Study 2 further investigated the mediating roles of moral responsibility and trust in airlines within this interaction. Study 3 used real-world surveys to examine the moderating influence of moral elevation, thereby supporting the interactive effects and mediation mechanisms identified in the earlier studies.
Findings
Across three studies, the authors consistently identified pivotal factors shaping COPIt in the context of air travel. Study 1 revealed that the combination of BA and GF significantly impacts COPIt, with egoistic appeals linked to loss framing and altruistic appeals connected to gain framing being particularly effective in encouraging COPIt. Study 2 extended these insights by showing that moral responsibility and trust in airlines serve as mediators between BA, GF and COPIt. In Study 3, moral elevation was found to moderate the influence of BA and GF on both moral responsibility and COPIt, deepening the understanding of these dynamics.
Originality/value
This study expands the range of factors affecting COPIt and delves into the underlying mechanisms through which BA and GF shape COPIt. Additionally, it advances current understanding by revealing the intricate processes influenced by moral elevation. The findings not only contribute to the existing knowledge on COPIt determinants but also offer practical guidance for the aviation industry and related sectors in promoting tourists’ participation in carbon offset programs.

Abstract
Purpose
This study aims to examine the impact of CEO age on corporate financialization by considering the moderating effects of CEO gender, identity and tenure in this relationship.
Design/methodology/approach
The analyses use ordinary least squares across 213 nonfinancial firms listed in Bursa Malaysia throughout 2015–2021. The author addresses potential endogeneity through propensity score matching and the generalized method of moments. The results are also robust to alternative measures of corporate financialization and CEO age.
Findings
The results show that firms with young CEOs are more likely to avoid taking short-term financial investments and, as a result, inhibit corporate financialization. Furthermore, the findings indicate that firms with female CEOs and those with family members as CEOs are less likely to invest in financial assets. The results also show that corporate financialization is weakened in the early stages of CEO tenure and strengthened in the late stages.
Practical implications
The empirical results have useful policy implications. For researchers, this study finds prominent differences in corporate financialization related to each stage of a person’s career. The study findings can be used by policymakers to guide programs that attempt to undertake the necessary measures to optimize corporate governance standards and restrict managers’ shortsighted conduct. In the long run, these kinds of projects could improve the way surplus financial reserves are used and raise economic output in general. The study also provides investors with insightful information about the possible relationship between CEO traits and company performance, especially with regard to measures for financial resource allocation.
Originality/value
This paper expands the existing research on corporate investment behavior and provides a new theoretical basis for the underlying factors of corporate financialization. It studies the influence of managerial traits on corporate financialization and deepens the understanding of CEO age and companies’ financialization levels.
