In this study, we investigate a nonlinear heat equation incorporating both a viscoelastic term and a reaction-diffusion term that depends on space-time variables. Initially, we establish the local Hadamard well-posedness results using the standard Faedo-Galerkin method. Subsequently, we demonstrate that the solution exhibits finite-time blowup for initial energy values that are both negative and nonnegative. Finally, we establish the global existence of the solution and provide general decay estimates for the energy functions with small initial energy, utilizing Martinez’s inequality.

The transportation sector is one of the main sources of greenhouse gas emissions, exacerbating environmental pollution and climate change. This has a significant economic effect on sustainable performance (SUS). This study aims to understand how digital technology adoption (DIG) affects SUS, considering the mediating role of circular economy practice (CIR). The research surveyed 706 individuals working in small and medium-sized enterprises in the transport industry in Southern Vietnam, employing quantitative and qualitative methods for analysis. The findings reveal that CIR has a positive effect on SUS. DIG has a positive impact on CIR and SUS. Additionally, the results also confirm the positive mediating role of CIR in the effects of DIG on SUS. The research results have made certain theoretical contributions. These insights also provide practical implications for policymakers and managers in the transportation sector to foster holistic sustainable development in Vietnam.

Previous studies have largely ignored the role of green practices as a value cocreation strategy to generate positive experiences for consumers and retrieve their values for luxury hotels. By adopting service‐dominant logic and engagement theory, this study establishes a model focusing on green value cocreation experience, including green participation and green value in use, as the starting point that leads to green satisfaction and emotional attachment and ultimately, customer brand engagement with environmental apathy as a boundary condition. To test the hypotheses, partial least squares structural equation modeling (PLS‐SEM) is utilized on a sample of 401 luxury hotel guests. The testing results confirm the proposed hypotheses, suggesting that green value cocreation experience can foster green satisfaction and emotional attachment and finally, customer brand engagement under the moderating role of environmental apathy. Based on the results, some important theoretical and practical implications are proposed.

This study examines the relationships between carbon emissions, firm‐level climate change exposure, and corporate cash reserves, with a focus on whether climate exposure mediates the link between carbon emissions and cash holdings. Using a dataset of 15,889 firm‐year observations from 2,537 firms across 51 countries during the period 2002 to 2021, the findings reveal a partial mediating effect of climate change exposure on the relationship between carbon emissions and corporate cash reserves. Specifically, firms with higher carbon risks tend to exhibit increased climate exposure, as reflected in earnings conference calls, which subsequently leads to higher cash reserves. This pattern is consistent across both general indicators of climate exposure and firm‐specific vulnerabilities to regulatory changes. Furthermore, the results remain robust after addressing endogeneity concerns through difference‐in‐difference estimations based on the Paris Agreement (COP21) event. These insights deepen our understanding of how high‐carbon‐emitting firms adjust their cash management strategies in response to market concerns about climate change.

In this fast and unprecedented changing world, graduate students are to be competent in dealing with the social problems and contribute to uplift the communities and save the planet they are living in. It is undeniable that academics play a crucial role in helping students to achieve the mentioned outcomes. The purpose of this study is to explore the factors influencing the pursuit of institutional work for social innovation among academics in Vietnamese higher education institutions (HEIs). A qualitative research design along with the theories of self-determination and institutional work was deployed. Twelve participants, who are practitioners, researchers and lecturers from a social enterprise and seven universities across Vietnam, were invited to join seven deep interviews conducted in the form of individual conversations and focus groups. A hybrid methodology of both inductive and deductive reasoning provides significant opportunities to approach and obtain the robust analysis of the empirical data. Apart from the findings of specific needs that successfully motivate the academics, the study also highlights the factors influencing SI promotion among academics in Vietnamese HEIs. Feasible initiatives are also recommended for practitioners seeking to cultivate social innovation within HEIs. The study also offers avenues for further research and exploration in the domain of psychological needs and institutional work.

Traditionally, firms have pursued the objective of maximizing firm value. However, the concept of business ethics has undergone a transformation and is now referred to as corporate social responsibility (CSR), which holds significant importance in today’s business landscape. The contemporary understanding of CSR emphasizes that a firm, as a corporate citizen, is not only accountable for its economic obligations but also for its social and environmental commitments. Built on this new definition, this study aims to empirically investigate the relationship between corporate sustainability development and performance of small and medium enterprises (SMEs) over the period from 2002 to 2018. By analyzing empirical data within an international context, the main finding reveals that fulfilling CSR has a significantly positive impact on firm profitability. However, the nonlinear model demonstrates that the development of corporate sustainability follows a U-shaped curve in relation to firm performance in terms of profitability, financial fragility, and market value. Additionally, our findings highlight that the impact of sustainability development on firm performance is more pronounced in countries with high government spending. The implication suggests that firms should consider socially responsible investment as an integral business strategy, as it has the potential to foster sustained growth. By adopting this approach, firms can simultaneously fulfill their role as responsible corporate citizens while enhancing their overall long-run performance.

The impact of tax planning and ESG disclosure on firm value, particularly in emerging markets like Vietnam, has not been widely studied. This research aims to fill that gap by examining how these two factors influence firm value, specifically in Vietnam. Using data from 206 companies listed on the Ho Chi Minh Stock Exchange from 2012 to 2021, the study looks at how foreign board membership affects the relationship between ESG disclosure, tax planning, and financial performance. The results show a negative link between tax planning, measured by the effective tax rate, and firm value. On the other hand, foreign board membership and ESG disclosure are both significant positive factors for firm value. Additionally, companies with foreign board members who implement ESG practices see a significant increase in firm value.

Renewable energy consumption has become increasingly prevalent worldwide, spanning across both developed and developing nations. This paper delves into the intricate dynamics among economic growth, governance, and renewable energy consumption within developing countries. Specifically, it investigates the moderating role of governance in shaping the relationship between economic growth and renewable energy consumption. Drawing upon data from 2000 to 2020 from nine selected Southeast Asian countries (ASEAN), this study employs fully modified ordinary least squares (FMOLS) estimation techniques. Furthermore, it scrutinizes the marginal effects of economic growth on renewable energy consumption across diverse levels of governance. Empirical findings suggest that economic growth generally augments renewable energy consumption, with the impact being either dampened or amplified by various indicators of good governance. These results underscore the nuanced influence of good governance in the nexus between renewable energy consumption and economic growth. Consequently, policymakers are encouraged to consider the multifaceted roles of good governance to facilitate the expansion of renewable energy consumption.

Despite significant investments in the drainage system by the Ho Chi Minh City government, urban flooding remains a pervasive issue. This paper investigates the willingness of local households to financially contribute to a new flood control system designed to mitigate high tide-induced inundation. Utilizing the Contingent Valuation Method (CVM), our findings indicate that residents are prepared to contribute between 220,000 VND and 250,000 VND for the project’s implementation. This study provides policymakers with demand-side evidence to inform decisions on urban flood control initiatives.

As people become more aware of the alarming environmental problems, actions to promote a sustainable economy and a better ecological environment are called. One of the most promising ways is green credit, which positively impacts the environment. This paper investigates how green credits in banks’ portfolios affect their performance, providing evidence from banks operating in Vietnam. The research is based on the panel data of 30 selected banks out of 49 banks operating in Vietnam from 2015 to 2022 from consolidated financial statements and annual reports. The study uses panel unit root tests and a fixed-effects model with moderation. The Hausman and joint F-test research results confirm that the fixed-effects model was the most appropriate method for identifying how green credit impacted the relationship between various factors and Vietnamese bank performance. Our research shows that green credit affects bank performance. Specifically, the presence of green credits in bank loan portfolios reduces the impact of the loans-to-deposit ratio, but not the bank size and capital adequacy, on both banks’ ROA and ROE, which implies that banks should implement green credit policy to mitigate the liquidity risks.

The objective of this investigation is to evaluate the influence of niche market leadership (NML) on market globalization orientation (MGO) by means of an intelligent cloud-based accounting information system (ICAIS). The study also examined the moderating function of industry dynamism (IND) in the relationship between NML and ICAIS as well as the relationship between ICAIS and MGO. The data obtained from a convenience and snowball sample of respondents employed in small and medium companies (SMEs) in Vietnam was analyzed using Partial Least Squares-Structural Equation Modeling (PLS-SEM) with the assistance of SmartPLS 4.1.0.6. The results clearly showed that NML had a significant and beneficial effect on MGO. The findings eventually demonstrated that the association between NML and MGO was partially mediated by ICAIS. The statistical outcomes also highlighted the moderating role of IND in the relationship between NML and ICAIS as well as the relationship between ICAIS and MGO. Broadly speaking, this study offers valuable insights for managers, stakeholders, and policymakers to comprehend on how to foster MGO through leveraging the potential of NML and ICAIS.

Having access to food is a human entitlement and one of the essential goals of the sustainable development agenda. Despite growing concern about the impact of slow‐onset disasters on food security, most interventions have primarily targeted sudden‐onset disasters. As such, there has been limited attention to understanding the effectiveness of adaptation strategies in safeguarding food security during disaster events. The aim of this research was to synthesize all existing evidence on the effectiveness of adaptation strategies in addressing food insecurity during gradual‐onset disasters. This study employs Hadley et al.'s food security framework to examine the effectiveness of existing adaptation strategies in mitigating food insecurity concerns during slow‐onset disasters. A mixed‐method systematic review was conducted using five electronic databases up to July 2023 and followed the guidelines regarding the convergent segregated approach to synthesize the findings. The review showed that most studies (94.1%) focused on drought, neglecting other slow‐onset disasters. The strategies mostly focused on ensuring the availability and accessibility of food while giving little attention to food utilization. Most food security components have somewhat identified their effectiveness, except for food safety, with no studies exploring it. Findings from the mixed‐methods approach also highlight the double‐edged effects of adaptation strategies and the notable absence of reliable intervention evidence using randomized controlled trials. It is crucial for future research to broaden the scope to include the less studied types of slow‐onset disasters. Emphasizing neglected and underutilized species, along with food safety aspects, might unveil novel approaches to boost food utilization in fluctuating climates. Given the heterogeneous nature of slow‐onset disaster impacts, it is important to explore these dynamic and context‐specific aspects of adaptation strategies in different conditions. Utilizing methods like randomized controlled trials in future research will enhance the evidence base.

This article offers a comprehensive overview of Business Sustainability (BuS), and directly addresses the lack of consensus around this important concept. Through a mixed-methods approach, we conduct the first systematic literature review of BuS employing Latent Dirichlet Allocation (LDA) topic modeling to uncover hidden thematic structures, Narrative Synthesis to refine and extend BuS definitions within different contexts, and the LDA-HSIM method to classify topics and design a new framework. We analyzed an extensive dataset comprising 92,311 articles sourced from 11,579 journal outlets. From this dataset, we identified 9,561 articles suitable for LDA topic modeling by applying funnel criteria, focusing on articles with clear theoretical underpinnings. A text extraction technique enabled us to identify and analyze theories used in BuS studies. This analysis revealed 150 underlying theories that advance the BuS concept across different research topics. The study contributes to BuS theory development with great potential to improve ethical decision-making by establishing meaningful, context-specific definitions and providing clear guidance for future researchers in selecting appropriate theoretical perspectives for their work. We identify research gaps, propose a prioritized research agenda focused on theory development, and formulate key implications for practitioners and policymakers. This study demonstrates the effectiveness of machine learning methods in conducting large-scale literature reviews to accelerate theoretical advancements and generate research agendas.

The goal of this paper is to investigate the finite‐time blow‐up of weak solutions to a class of wave equations involving the fractional 1/2 1/2 ‐Laplace operator with critical exponential growth, where the initial energy is supercritical. These results extend the recent work regarding the finite‐time blow‐up of weak solutions. We emphasize that there are no effective methods to study this problem. Hence, we need to find some suitable assumptions and the appropriate technique to achieve this.

Only a small portion of entrepreneurs who would like to be their own bosses eventually succeed and maintain their own businesses after the initial startup phase. Building upon self-determination theory, we develop a conceptual model that examines the relationships among harmonious passion, entrepreneurial persistence, time-based resources and career achievement of entrepreneurs. In Study 1, we collected longitudinal survey data using two measurement waves and found that harmonious passion affects career achievement directly and indirectly via entrepreneurial persistence. Time-based resources were found to moderate the impact of entrepreneurial persistence on career achievement. The fuzzy-set qualitative comparative analysis results confirmed that personal resources (harmonious passion, persistence and time-based resources) are needed as prerequisites for career achievement. In Study 2, we conducted an experiment and confirmed the findings in Study 1. Our research extends the existing theory and suggests implications for entrepreneurs.

Drawing upon social exchange theory and extending it into a team context, this study investigated a moderated mediation model in which shared team psychological contract fulfillment mediates the relationship between inclusive leadership and team innovation, and team proactive personality moderates the relationship between inclusive leadership and shared team psychological contract fulfillment. The results, based on a survey dataset collected from 300 team leaders in retail services in Vietnam, provided support for these relationships. The study findings extend the existing literature on inclusive leadership and psychological contract fulfillment to the team level and suggest possible ways for team leaders to enhance team innovation performance. 概述 本研究借助社会交换理论并将其延伸至团队环境中去，进而对一 项有调节的中介模型进行了深入的调查学习。在此模型中，共同 团队心理契约满足能促成在包容性领导力和团队创新力之间建立 起关系。此外，团队积极性人格也能对包容性领导力和共同团队 心理契约满足的关系起到调和的作用。研究中的调查数据源自越 南零售业的300名团队领导，研究结果为上述这些关系提供了支 持。对于现有的关于包容性领导力和心理契约满足的文献，本研 究结果能令其延伸拓展至团队层面，并且也为领导如何提升团队 创新表现力提供了潜在的解决方法。 ARTICLE HISTORY
