In the rapidly evolving digital environment, organizations face increasing pressure to adapt to technological advancements while ensuring long-term sustainability. This study was motivated by the critical need to understand how human resource (HR) leadership can effectively foster digital skills development to drive economic sustainable development. Recognizing that digital competencies are now essential for organizational resilience and competitiveness, this research explores the interplay between HR leadership, digital skills acquisition, and economic sustainable development. This study employed the SERVQUAL tool to assess gaps between employee expectations and perceptions across key demographic variables, including age, education level, and employment status. Data collected from 476 participants across several European Union countries underscore the significant influence of demographic factors on these perceptions. The findings reveal a high alignment between employee expectations and perceptions, reflecting the importance of HR leadership in bridging the digital skills gap. Moreover, this study highlights the necessity of integrating HR leadership practices to ensure that digital transformation contributes not only to immediate organizational goals but also to long-term economic sustainable development. This research provides valuable insights into the role of HR leadership in navigating the challenges of the digital era, ultimately offering a framework for fostering a skilled, adaptable, and sustainably oriented workforce.

The study of health and medical tourism is a multifaceted and intricate field. Nevertheless, it is a swiftly expanding global industry with considerable economic prospects. This sector involves the exchange of services, blending two of the world’s major domains: healthcare and tourism. This research aims to evaluate the strengths of medical tourism service providers in the Central Macedonia Region while shedding light on various challenges that could impede the sector’s growth. Additionally, it investigates crucial sustainability factors and opportunities within the Greek medical tourism industry that can effectively address obstacles, both domestic and international, to enhance sustainable medical services. The study delves into the reasons why the Central Macedonia Region can attract both local and international medical travelers seeking healthcare solutions. With this aim in mind, both Systematic Literature Review (SLR) and primary quantitative research methods were employed. The SLR aimed to locate pertinent scientific literature, which, when integrated with the outcomes of the quantitative research, facilitated the analysis, description, and interpretation of data for the formulation of conclusive findings. In brief, this article aims to contribute scientific value by engaging in interdisciplinary research and demonstrating originality through innovative approaches to sustainable development. It seeks to make a significant contribution to the field by presenting practical strategies and insights that strike a balance between the economic advantages of medical tourism and the crucial considerations of environmental and social impact.

This study investigates the impact of various educational and social factors on the digital skills of vocational education and training (VET) students, emphasizing the significance of continuous skill development in the digital age. Utilizing structural equation modeling (SEM), the paper analyzes data from 382 adult VET students in Greece, examining the effects of Erasmus program participation, daily computer use, educational platforms, and social network engagement on digital competencies. The findings reveal that participation in Erasmus programs and the use of educational platforms significantly enhance students’ digital skills, highlighting the value of international experiences and digital learning tools in VET. Conversely, daily computer use alone does not significantly impact digital skills, suggesting that structured and purposeful digital tool integration is essential for skill development. The study also underscores the positive role of social networks in improving content management skills, advocating for their strategic use in educational settings. These results demonstrate the need for targeted digital literacy initiatives within VET programs to prepare students for modern labor market demands. The research contributes to the theoretical understanding of digital skill acquisition and offers practical insights for educators and policymakers to enhance VET curricula, fostering economic and social progress through improved digital literacy.

This study explores how Human Resource Management (HRM) can help organizations to face the challenges of digital transformation, focusing on reducing digital inequalities and improving employee performance. As digital tools become more important in workplaces, many employees still experience digital exclusion, which affects not only their productivity but also their sense of fairness and inclusion, as well. To investigate these issues, quantitative research was conducted using a structured questionnaire distributed online to employees across EU-based companies. The data were analyzed through PLS-SEM, including IPMA and mediation analysis, to understand the relations between HRM practices, digital skills, and perceptions of organizational justice. The findings show that HRM strategies have a significant impact on bridging the digital divide, especially by promoting digital adaptability and supporting inclusive work environments. Inclusion was also found to mediate the relation between HRM and employee performance. This research offers practical suggestions, like using Key Performance Indicators (KPIs) to monitor digital participation and encouraging continuous learning. The study adds value by connecting digital empowerment with HRM policies in a way that supports both organizational efficiency and equality. Future research could focus on specific sectors or use longitudinal data to better capture how digital inclusion develops over time.

Wine communication management is a continuous effort to deliver a communication framework that is built on many factors such as the terroir, the grape variety, the geographical indication, the geomorphological profile of each wine zone, the producer’s philosophy, the winemaking methods, and finally the general cultural and social contribution. This paper attempts to run a systematic literature review in the field of wine communication focused on wine labels. The research is based on the combined keywords, “wine label” and “wine label communication” on databases in a range between 2010 and 2024. The purpose of this paper is to provide useful insights to researchers, students, and interested parties in the wine industry about the way dominant label information is decoded by consumers. The contribution of this work is to set a specific conceptual framework for wine label information that could be useful in the field of wine communication strategies.

Background/Objectives: Emotional intelligence has emerged as a key factor in shaping nursing performance and care quality, yet its specific mechanisms and impact within the Greek public healthcare context remain underexplored. This study aimed to investigate the role of emotional intelligence in ethical behavior, crisis management, and the perceived quality of care among nurses working in Greek public hospitals. Methods: A cross-sectional survey was conducted among practicing nurses using validated instruments to assess emotional intelligence, ethical compliance, crisis management skills, and care quality. Data were analyzed using covariance-based structural equation modeling (CB SEM) to examine both direct and indirect relationships among variables. Results: The results indicated that emotional intelligence training had a strong and significant effect on nurses’ ethical behavior and their ability to manage critical situations. However, the direct effect of emotional intelligence on the perceived quality of care was not significant; instead, its influence was mediated through improvements in ethics and crisis management. Conclusions: These findings suggest that the benefits of emotional intelligence in nursing are most evident when integrated with supportive organizational practices and ongoing professional development. Overall, this study highlights the need for comprehensive emotional intelligence training and a supportive workplace culture to enhance ethical standards, resilience, and patient care quality in Greek healthcare settings.
