2. Changes in emissions of NOx and PM2.5 as a result of the implementation of measures in sectors close to the population : energy efficiency in residential buildings, and passenger cars substitutionAna R. Gamarra, Marta G. Vivanco, Mark R. Theobald, Coralina Hernández, Yolanda Lechón, 2025, original scientific article Abstract: This paper examines different strategies for reducing air pollution through measures implemented in key sectors. Current environmental and energy policies at the European and Spanish levels are focused on increasing energy efficiency and the penetration of renewable energy sources. In this study, changes in emissions of two major pollutants affecting human health — nitrogen oxides (NOx) and fine particulate matter (PM2.5) — are quantified as a result of implementing a set of planned measures, considering Spain’s 2030 policy targets and using 2021 as the reference year. The measures target sectors that are directly connected to the population: residential buildings and passenger cars. The results indicate that the greatest benefits in terms of emission reductions are achieved through the replacement of combustion-based passenger road transport with electric vehicles, as well as through improvements to building envelopes, particularly once the electricity mix reaches the 2030 renewable energy penetration target.

3. Interdependence of nursing staff work engagement, quality of workplace relationships and patient safetyHilda Maze, Sanja Zorić, Bojan Rosi, Branko Lobnikar, 2023, original scientific article Abstract: Background and Purpose: Quality within a healthcare system does not comprise only actions defined through certificates or required by law, standards and protocols; it is also defined by the well-being of healthcare workers on the one hand and patients on the other. The purpose paper is to analyse the link between the engagement of nurses and factors related to enhancing patient quality and safety. Methods: The research involved 206 nursing employees from Slovenia’s general hospitals. The questionnaire con-sists of four sections: employee engagement, the measure of self-efficacy, statements referring to various tools and methods that are used in nursing in daily work and that contribute to the quality of work, interpersonal relationships in the workplace between different professional groups within medical treatment, and attitude towards changes.Results: Compared to other professions, nursing employees showed an above-average level of engagement. Younger respondents were more engaged in their work, and their self-efficacy level was higher. The frequency of using tools intended to enhance the quality of nursing correlates statistically typically and positively with self-effica-cy, engagement and willingness to accept change. The analysed factors are interdependent. Engagement results from workplace interactions; employees who feel better in their workplace will be more oriented towards the future, be more open to innovation, and use various tools and approaches to enhance the work’s quality.Conclusion: Analysed concepts are closely connected and interdependent. The findings are essential for the suc-cessful and efficient management of hospitals and for ensuring patient quality and safety.

5. Assessment of harmonic distortion in school buildings equipped with grid-connected PV systemsFranjo Pranjić, 2025, professional article Abstract: The integration of photovoltaic systems into power grids can impact power quality, particularly concerning voltage and current harmonics. This study investigates the power quality of a photovoltaic system integrated into the electrical system of an educational facility, focusing on harmonic distortion in both voltage and current. Comprehensive measurements were conducted across three phases and analysed according to the EN 50160 and IEEE 519 Standards. The results demonstrated that, while the voltage quality meets EN 50160 requirements consistently, indicating stable voltage levels, the current measurements revealed significant harmonic distortion. Notably, Phase 2 exhibited Total Harmonic Distortion values substantially above the acceptable limits, with Phase 1 and Phase 3 also showing elevated Total Harmonic Distortion. To address these issues, the study recommends the implementation of advanced harmonic filters and optimisation of inverter technologies. These measures are crucial for enhancing power quality, and ensuring compliance with the industry Standards in high photovoltaic penetration scenarios.
Keywords: power quality analysis, grid-connected PV systems, EN 50160 standard, IEEE 519 Standard, IEC 61000 standard, voltage harmonics, current harmonics, harmonic distortion, renewable energy integration, compliance assessment

7. Aligning business solutions and business requirements for digital transformation – case research : V.Uroš Zabukovšek, Simona Sternad Zabukovšek, Samo Bobek, 2025, independent scientific component part or a chapter in a monograph Abstract: This study explores how Business and IT Alignment (BITA) influences business performance (PERFO) and corporate sustainability (SPACS) using a mixed-methods case study of an international manufacturing enterprise. The quantitative analysis (PLS-SEM) indicated BITA affects PERFO indirectly through IT service quality (ITSQ), while remote work (EWORK), despite its relation to BITA, showed no significant impact. BITA strongly predicted SPACS by enhancing employees’ sustainability knowledge, confidence, and willingness to act. Qualitative findings from semi-structured interviews revealed a BITA maturity of 3.3 (on a 5-point scale), highlighting its role in sustainability via better decision-making, process optimization, and IT-enabled transparency. Notable discrepancies between managerial and employee perceptions of BITA maturity were identified. Results suggest successful BITA fosters sustainability-oriented behaviour and IT-driven performance improvements, though continuous reinforcement within organizations is required. The study emphasizes the value of integrating qualitative and quantitative methods for comprehensive insights into BITA's impact.
Keywords: business and IT alignment (BITA), IT service quality (ITSQ), business performance (PERFO), corporate sustainability (SPACS), remote work (EWORK), mixed methods research (MMR), PLS-SEM, organizational maturity, sustainability awareness, case study

8. Predicting wine quality under changing climate : An integrated approach combining machine learning, statistical analysis, and systems thinkingMaja Borlinič Gačnik, Andrej Škraba, Karmen Pažek, Črtomir Rozman, 2025, original scientific article Abstract: Climate change poses significant challenges for viticulture, particularly in regions known for producing high-quality wines. Wine quality results from a complex interaction between climatic factors, regional characteristics, and viticultural practices. Methods: This study integrates statistical analysis, machine learning (ML) algorithms, and systems thinking to assess the extent to which wine quality can be predicted using monthly weather data and regional classification. The dataset includes average wine scores, monthly temperatures and precipitation, and categorical region data for Slovenia between 2011 and 2021. Predictive models tested include Random Forest, Support Vector Machine, Decision Tree, and linear regression. In addition, Causal Loop Diagrams (CLDs) were constructed to explore feedback mechanisms and systemic dynamics. Results: The Random Forest model showed the highest prediction accuracy (R2 = 0.779). Regional classification emerged as the most influential variable, followed by temperatures in September and April. Precipitation did not have a statistically significant effect on wine ratings. CLD models revealed time delays in the effects of adaptation measures and highlighted the role of perceptual lags in growers’ responses to climate signals. Conclusions: The combined use of ML, statistical methods, and CLDs enhances understanding of how climate variability influences wine quality. This integrated approach offers practical insights for winegrowers, policymakers, and regional planners aiming to develop climate-resilient viticultural strategies. Future research should include phenological phase modeling and dynamic simulation to further improve predictive accuracy and system-level understanding.

9. Human capital efficiency and firm performance of quality-certified firms from EFQM excellence model : a dynamic panel data studyMuhammad Yousaf, 2024, original scientific article Abstract: Purpose: The study’s main purpose is to investigate the impacts of human capital efficiency (HCE) on the firm performance of non-certified and quality-certified firms from the European Foundation for Quality Management (EFQM) Excellence Model. The study also examines the relationship between firm performance and quality-certificates from the European Foundation. Design/methodology/approach: By using a sample of 282 non-certified and 22 quality-certified firms from 2017 to 2021, the current study employed a two-step system generalized method of moments (GMM) estimation to analyse the empirical data. The dummy variable is used to examine the relationship between quality-certificates and firm performance. The dummy interaction term is employed to quantify the impacts of HCE on the firm’s performance for quality-certified firms. Findings: The results revealed that quality-certificates and firm performance have a positive relationship. Quality-certified firms perform better and earn more profits than non-certified firms. HCE has a positive impact on firm performance for both types of firms. Moreover, the quality-certified firms utilize HCE in an efficient way to earn more profits compared to the non-certified firms. Originality: This is the first study to use a comprehensive analysis to emphasize the HCE for non-certified and quality-certified firms separately. The effects of quality-certificates on firm performance in the context of HCE are also being highlighted for the first time in this research. Practical implications: The current study’s findings are fruitful for academics, managers, researchers, policymakers, and other firm management. The findings will encourage the management of the firms to implement the total quality management (TQM) approach within their firms.
Keywords: human capita, quality management, Czech firms, firm size, firm age

10. Having each other’s back : the mediating role of supportive behaviours in the relationship between team autonomy and team effectivenessJoana Alexandrino, 2024, original scientific article Abstract: Background and Purpose: Incorporating autonomy in teams has been an increasingly popular practice, but the mechanisms that make autonomous teams effective still need to be completely understood. Adopting a multidimensional approach to team effectiveness, the aim of this study was to analyse the mediating role of team members’ supportive behaviours in the relationship between team autonomy and team effectiveness (team performance, team viability, quality of group experience and team process improvement). Methods: This research adopts a group-level analysis with a sample of 90 teams of 40 organisations from different sectors. Regression analysis was used to analyse the data, namely the product of the coefficients method. Results: A positive relationship between team autonomy and supportive behaviours, which, in turn, is positively related to the four criteria of team effectiveness, was found, suggesting that supportive behaviours are a team process that explains the relationship between team autonomy and team effectiveness. Conclusion: This research enriches our knowledge of the antecedents of team effectiveness and explains the mechanisms through which team autonomy relates to team effectiveness, encouraging organisations to incorporate autonomy into teams’ design to enhance supportive behaviours and team effectiveness.
