Abstract
Purpose
To overcome the limitations of traditional multi-attribute decision making (MADM) methods, which only provide deterministic rankings of decision objects, this paper proposes a novel multi-attribute 3WD model. This model presents three-parameter interval grey number decision-theoretic rough sets (TPIGNDTRSs), aiming to offer a reasoned interpretation of loss functions in grey environments and ensure objective assessment of conditional probabilities.
Design/methodology/approach
Firstly, the traditional equivalence relation is replaced with the probabilistic dominance relation (PDR), categorizing decision objects into two state sets in DTRS for more objective conditional probabilities. Secondly, as the three-parameter interval grey number (TPIGN) introduces the most probable value on the basis of the traditional two-parameter interval grey number, it provides a more comprehensive method for describing grey information. Consequently, integrating TPIGN into DTRS refines the interpretations of loss functions in grey environments. Finally, by utilizing two main sorting techniques, relative kernel and degree of accuracy ranking and possibility ranking, two types of 3WD rules with TPIGNDTRSs, are constructed.
Findings
This study has successfully developed and validated a new multi-attribute 3WD model. The model was tested in two distinct domains: evaluating innovation efficiency in high-tech enterprises and recommending movies in a practical case. The findings reveal that the model can effectively integrate relevant information of high-tech enterprises, provide the government with enterprise-level assessments, and gather consumer preferences to recommend the most suitable movies.
Research limitations/implications
This study treats the loss function as grey information in the 3WD model but overlooks the grey nature of evaluation values, limiting its applicability. Additionally, the model’s reliance on subjective expert judgments and historical data to establish the loss function may affect its objectivity. The implications of this research are that the novel model overcomes traditional MADM limitations, enhancing decision-making quality and efficiency in complex and grey scenarios. The model’s successful application in evaluating high-tech enterprises and recommending movies illustrates its dual value in both theory and practice.
Originality/value
Initially, the model proposed in this study is of significant importance for the development of the 3WD field, as it successfully addresses the challenges of uncertain loss functions and unknown conditional probabilities in grey information environments. Moreover, by integrating the 3WD model with MADM problems, it has broken through the bottlenecks of traditional MADM methods, offering new perspectives and strategies for solving MADM issues. Therefore, this research not only advances theoretical research but also provides powerful tools for practical applications.

Abstract
Purpose
This study aims to provide a comprehensive overview of social contract theory (SCT) utilization in cybersecurity literature, elucidating the current state of research, identifying major applications and themes and highlighting gaps, particularly in empirical studies, and the integration of emerging technologies. The study also maps the contractual parties and governance tools discussed in SCT and cyberspace interactions.
Design/methodology/approach
This study uses a systematic literature review to investigate the application of SCT within the cybersecurity domain. Using a mixed-methods approach that combines quantitative and qualitative content analysis with the Grounded Theory strategy, over 30,000 documents were initially screened. The final data set comprised 873 peer-reviewed papers from multiple databases. MAXQDA software facilitated coding and thematic analysis to identify key SCT applications, governance tools and research gaps.
Findings
The review revealed the following: emerging technologies such as artificial intelligence (AI) and blockchain are sparsely researched within the SCT-cyberspace intersection, yet they offer solutions to various SCT-related issues; empirical studies are underrepresented, with theoretical explorations dominating the discourse; there is a notable gap in integrating emerging technologies such as AI within SCT frameworks; governance tools discussed are varied, including economic incentives, regulatory measures and informational strategies.
Originality/value
This study synthesizes SCT applications in cybersecurity, highlighting the interdisciplinary nature and potential for richer theoretical integration. By systematically mapping the literature, it identifies crucial gaps and offers a foundation for future empirical and theoretical research. The findings emphasize the importance of considering traditional SCT themes and contemporary technological contexts, contributing to the development of more robust frameworks for cyberspace governance.

Abstract
Purpose
This study aims to provide insights into wine consumers in Hong Kong and Mainland China, and the diversity of their behavior, by investigating their motivations, consumption and purchasing behavior and segmenting the sample based on wine knowledge and frequency of consumption to identify three distinct clusters that are then profiled.
Design/methodology/approach
Data was collected through an online survey of wine consumers of ethnic Chinese origin residing in Mainland China and Hong Kong, using two methods of recruitment (a convenience sample from wine-related databases, a panel survey undertaken by an international market research firm). The final sample comprised 477 respondents, about equally divided among Mainland Chinese and Hong Kong wine consumers. Analysis of the data using the Statistical Package for Social Sciences for Windows (SPSS) 29 included a series of descriptive analyses, followed by a two-step cluster analysis using an Euclidean distance method.
Findings
Wine knowledge and frequency of wine consumption were relatively higher within the sample as a whole than previous studies, but three distinct consumer segments are evident. There is evidence of a democratization of wine consumption, and a greater focus on wine consumption for enjoyment in relaxed and informal settings. rather than consumption driven by health and status, occurring primarily in commercial or business settings. The dominance of red wine in this market is also declining, and intrinsic cues – specifically, prior experience of the wine – are becoming important in wine purchase decisions.
Originality/value
This study uses a broad sample of wine consumers to identify trends in wine consumption patterns and motivations, and purchase decision-making behavior, of Mainland Chinese and Hong Kong wine consumers. The identification of three clusters of wine consumers offers both points of comparison with previous segmentation research globally and within China, whilst also identifying scope for further research.

Abstract
Purpose
Morality in the workplace has become a significant determinant of organizational effectiveness and employee well-being. This research aims to conduct an in-depth review of the past literature on multidimensional morality and provide insight into its impact on the modern workplace and employee well-being.
Design/methodology/approach
The literature search resulted in 3,589 papers published between 2012 and 2024. This paper analyzed 30 research studies on workplace morality based on predetermined inclusion and exclusion criteria to ensure methodological rigor.
Findings
Research findings show the need to promote workplace ethics to avoid counterproductive workplace behaviors. Also, effective leadership adheres to ethical principles, together with the ethical framework of an organization, which includes codes of ethics and a commitment to corporate social responsibility, contributing to the overall well-being of individuals by providing a sense of support and resolving conflicts. Ethical conflicts are associated with decreased well-being and increased turnover, underscoring the need for organizational solutions.
Practical implications
Understanding intricate morality is essential for organizations to foster moral cultures and improve performance. HR specialists can use this knowledge to create policies that uphold moral principles and improve employee job satisfaction.
Originality/value
This study extends the current body of knowledge by synthesizing research on multifaceted moral issues in modern workplaces. It provides useful insights for researchers, practitioners, and policymakers who are interested in promoting ethical organizational cultures by addressing ethical shortcomings.

Abstract
Purpose
This paper aims to determine the conditions for the core of the Triple Helix game to exist. The Triple Helix of university-industry-government relationships is a three-person cooperative game with transferable utility. Then, the core, the Shapley value and the nucleolus were used as indicators of the synergy within an innovation system. Whereas the Shapley value and the nucleolus always exist, the core may not.
Design/methodology/approach
The core of a three-person cooperative game with transferable utility exists only if and only if the game is convex. The paper applies the convexity condition to the Triple Helix game.
Findings
The Triple Helix game is convex if and only if there is output within the system; it is strictly convex if and only if all the three bilateral and the trilateral relationships have an output.
Practical implications
Convex games are competitive situations in which there are strong incentives towards the formation of large coalitions; therefore, innovation actors must cooperate to maximise their interests. Furthermore, a Triple Helix game may be split into subgames for comprehensive analyses and several Triple Helix games may be combined for a global study.
Originality/value
This paper extends the meaning of the Shapley value and the nucleolus for Triple Helix innovation actors: the Shapley value indicates the quantity a player wins because of the coalitions he involves in and the nucleolus the return for solidarity of an innovation actor.

Abstract
Purpose
Climate change, driven by global warming, poses a significant threat to humanity and disrupts the ecological balance. In Europe, concentrations of air pollutants remain very high, and problems related to air quality and the acceleration of the phenomenon of global warming persist. As a result, carbon taxation has emerged as a key strategy to mitigate climate change. In Romania, environmental taxes are an important instrument of environmental policy as an economic instrument for environmental protection and natural resource management. Using 1990–2021 time series data and an Autoregressive Distributed Lag (ARDL) Bounds cointegration for long-run analysis and the Toda–Yamamoto test for causality analysis, we investigated whether environmental taxes, renewable energy consumption, urbanization and economic growth significantly impact CO2 emissions in Romania.
Design/methodology/approach
This paper differs from the assessment of the Environmental Kuznets Curve (EKC) hypothesis (Grossman and Krueger 1991) and instead aims to determine the impact of environmental taxes, renewable energy consumption, per capita GDP and urbanization on CO2 emissions in Romania. The study investigates both short- and long-term effects, as well as Toda–Yamamoto causality linkages (Toda and Yamamoto 1995) between these variables. We adopt an ARDL estimation technique with Bound cointegration test and error correction models (Pesaran et al., 2001) to examine the short- and long-term effects.
Findings
The findings revealed that environmental taxes positively and significantly reduce CO2 emissions, while urbanization induces CO2 emissions, in the long run. Moreover, in the short run, environmental taxes and renewable energy consumption significantly reduce CO2 emissions while per capita GDP and urbanization significantly increase CO2 emissions. A unidirectional causality exists between renewable energy consumption and CO2 emissions. Thus, to realize its 34% target of renewable energy consumption in 2030, Romania should prioritize the implementation of the Casa Verde Plus program and enforce sustainable urban planning to meet near-zero energy standards. Consequently, the government should continue to enforce carbon taxes to promote environmental sustainability.
Originality/value
Empirical evidence supports the cointegration relationship between environmental taxes and CO2 emissions, with carbon taxes effectively reducing CO2 emissions and improving environmental quality (Allan et al., 2014; Polat and Polat, 2018; Kiuila et al., 2019, etc.). While existing research (Floros and Vlachou, 2005; Wissema and Dellink, 2007; Aydin and Esen, 2018; Lin and Li, 2011) primarily focuses on country-specific or regional analyses, limited research has been conducted on the impact of carbon taxation on CO2 emissions in Romania. However, to the best of our knowledge, limited research on this phenomenon in Romania exists in response to recommendations for climate change mitigation. Furthermore, urbanization has significantly contributed to rising atmospheric carbon levels and subsequent global warming and climate change (Woldu, 2021). As economic growth, particularly in countries like Romania, drives urbanization, it leads to increased energy demand, expanding urban areas and mounting environmental concerns. This process involves industrial restructuring, and the development of new infrastructure, all of which exert pressure on energy consumption and CO2 emissions (Niu and Lekse, 2018). While economic growth is a primary objective, industrialization and urbanization inevitably generate unintended consequences, including CO2 emissions. However, limited research exists on the impact of urbanization patterns on CO2 emissions in Romania. This study investigates the dynamic causal relationships among urbanization, per capita GDP, carbon taxes, renewable energy consumption and CO2 emissions, considering both short-run and long-run effects in Romania.

Abstract
Purpose
This study aims to examine the impact of COVID-19 pandemics on subjective well-being (SWB) and mental health in Hungary, with a particular focus on the roles of socioeconomic and COVID-19-related factors in shaping these outcomes.
Design/methodology/approach
A cross-sectional online survey was conducted among 2,000 Hungarian adults from May 25 to June 8, 2021. The data was collected using standardized questionnaires, including the SWLS, GAD-7 and PHQ-9. Correlation analysis, one-way ANOVA and linear regression were used.
Findings
The study found significant anxiety (41.5%), depression (48.1%) and life dissatisfaction (41.9%) among 2,000 participants. Females reported higher anxiety and depression than males. Single individuals had the lowest life satisfaction. Higher income levels are correlated with greater life satisfaction. Quarantine and vaccination were linked to higher life satisfaction and lower psychological distress. The regression showed that older age, being married and higher income were linked to lower depression and anxiety. Severity of infection and quarantine increased both depression and anxiety. Infection reduced life satisfaction, but severe cases showed a slight improvement in satisfaction, highlighting complex health and well-being relationships.
Practical implications
The findings reveal complex relationships, including unexpected resilience in severe COVID-19 cases.
Originality/value
This study offers insights into the impact of the COVID-19 pandemic on SWB and mental health in Hungary. By analyzing socioeconomic, demographic and pandemic-related factors in a large sample, it highlights complex relationships between quarantine, infection severity, vaccination and well-being. The findings contribute to understanding how these factors influence mental health, informing targeted interventions during health crises.

Abstract
Purpose
This paper focuses on the commitment of a leading Middle Eastern country – Saudi Arabia – to the United Nations (UN) Sustainable Development Goals (SDGs), particularly SDG13, climate preservation. This paper aims to investigate the determinants of greenhouse gas emissions by examining their correlation with economic growth, population growth, renewable energies, forest area, digitalization and monetary policy.
Design/methodology/approach
This research observes greenhouse gas (GHG) emissions and the potential influencing factors during 1990–2023. It employs the autoregressive distributed lag model (ARDL) after testing the stationarity of the variables.
Findings
The findings show that population growth, gross domestic product (GDP) growth, percentage of individuals using the internet and forest rents are significant determinants of carbon oxide (CO2) emissions. Further, methane (CH4) emissions are significantly associated with population growth, GDP growth, percentage of individuals using the internet and renewable internal freshwater resources. Nitrous oxide (N2O) emissions depend significantly on the percentage of individuals using the internet and renewable internal freshwater resources.
Practical implications
This research helps policymakers in Saudi Arabia and worldwide identify the factors moderating GHG emissions, and accordingly design targeted interventions. These initiatives would substantially reduce GHG and further global climate goals. Additionally, focusing on Saudi Arabia, a significant emerging country in the Middle East, has broader implications. The findings offer insights that extend beyond its borders, providing valuable lessons for governments in the Middle East and worldwide to assess and improve their initiatives toward SDG13. Therefore, monitoring greenhouse gas emissions in this key country boosts global progress toward the UN’s 2030 Agenda for Sustainable Development. Furthermore, this paper aligns with the Principles for Responsible Management Education (PRME) by leveraging academic and managerial strategies toward sustainability and climate action initiatives.
Originality/value
This study adds to the limited literature on the determinants of GHG emissions in the Middle Eastern region, particularly in Saudi Arabia. In addition to CO2, it also focuses on CH4 and N2O emissions. It shows the beneficial effect of renewable internal freshwater resources. It uses the ARDL model to distinguish between the short- and long-run associations.
