Road freight transport forecasting : a fuzzy Monte-Carlo simulation-based model selection approach
Dejan Dragan, Simona Šinko, Abolfazl Keshavarzsaleh, Maja Rosi, 2022, izvirni znanstveni članek

Opis: As important as the classical approaches such as Akaike's AIC information and Bayesian BIC criterion in model-selection mechanism are, they have limitations. As an alternative, a novel modeling design encompasses a two-stage approach that integrates Fuzzy logic and Monte Carlo simulations (MCSs). In the first stage, an entire family of ARIMA model candidates with the corresponding information-based, residual-based, and statistical criteria is identified. In the second stage, the Mamdani fuzzy model (MFM) is used to uncover interrelationships hidden among previously obtained models criteria. To access the best forecasting model, the MCSs are also used for different settings of weights loaded on the fuzzy rules. The obtained model is developed to predict the road freight transport in Slovenia in the context of choosing the most appropriate electronic toll system. Results show that the mechanism works well when searching for the best model that provides a well-fit to the real data.

Is there a relationship between self-enhancement, conservation and personal tax culture?
Aleksandra Hlastec, Damijan Mumel, Lidija Hauptman, 2023, izvirni znanstveni članek

Opis: Sustainability gets higher on the policy agenda of many countries in terms of the UN Sustainable Development Goals. Unethical tax behaviour diminishes the tax system’s sustainability, but paying taxes is necessary if we want to contribute to society. There is a deeper need to understand the factors that influence taxpayers’ perceptions, personal values and personal tax culture. Previous research by the OECD (2013, 2019) using the World Values Survey (WVS) did not provide a sufficient explanation of all the socio-economic factors associated with personal tax culture. As the behaviour of an individual is shaped by a set of values, and values can provide predictive and explanatory power in the analysis of attitudes, opinions and actions by policymakers, it is necessary for them to understand such when proposing tax morale incentives within the institutional pillar. A literature review showed that the research topics on personal tax culture present specific assumptions and gaps. To contribute to this topic, a conceptual model was developed, and the relationship between personal values (conservation/self-enhancement), measured by the widely accepted and recognised Schwartz’s circular model, and personal tax culture was analysed with the aim of formulating recommendations for policymakers. The survey conducted in Slovenia involved 202 respondents. Based on exploratory factor analysis and the performed correlation analysis, empirical research suggests that a relationship between personal values and personal tax culture as the cornerstones of an individual’s tax-compliant behaviour and their attitude towards the ethics of tax evasion is significant. The correlation between personal values and an individual’s attitude towards the tax system is insignificant. By understanding the relationships between individuals’ personal and tax culture values, policymakers can achieve a greater sustainable tax system.

Perceptions of the primary health care team about the implementation of integrated care of patients with type 2 diabetes and hypertension in Slovenia : qualitative study
Nataša Stojnić, Zalika Klemenc-Ketiš, Majda Mori-Lukančič, Črt Zavrnik, Tonka Poplas-Susič, 2023, izvirni znanstveni članek

Opis: Background Integrated care involves good coordination, networking, and communication within health care services and externally between providers and patients or informal caregivers. It affects the quality of services, is more cost-effective, and contributes to greater satisfaction among individuals and providers of integrated care. In our study, we examined the implementation and understanding of integrated care from the perspective of providers - the health care team - and gained insights into the current situation. Methods Eight focus groups were conducted with health care teams, involving a total of 48 health care professionals, including family physicians, registered nurses, practice nurses, community nurses, and registered nurses working in a health education center. Prior to conducting the focus groups, a thematic guide was developed based on the literature and contextual knowledge with the main themes of the integrated care package. The analysis was conducted using the NVivo program. Results We identified 12 main themes with 49 subthemes. Health care professionals highlighted good accessibility and the method of diagnostic screening integrated with preventive examinations as positive aspects of the current system of integrated care in Slovenia. They mentioned the good cooperation within the team, with the involvement of registered nurses and community nurses being a particular advantage. Complaints were made about the high workload and the lack of workforce. They feel that patients do not take the disease seriously enough and that patients as teachers could be useful. Conclusion Primary care teams described the importance of implementing integrated care for diabetes and hypertension patients at four levels: Patient, community, care providers, and state. Primary care teams also recognized the importance of including more professionals from different health care settings on their team.

Transformation of the education system in agricultural advisory towards sustainability - A Case study in Slovenia
Marina Nikšić, Lazar Pavić, Črtomir Rozman, 2023, izvirni znanstveni članek

Opis: The new role that agricultural advisory plays in innovation processes and the development of agriculture towards sustainability requires the improvement of its performance. The basic prerequisite for realizing the potential of agricultural advisory in the areas mentioned is a strongly developed education system that will enable the development of strong advisory capacities. This survey is based on three areas of the education system: organization of education, satisfaction with educators, and evaluation of education and the potential of individuals in the organization. The basic principles on which the education system is based are outdated and, therefore, inadequate for developing the performance that the new role of agricultural advisors in innovation processes requires. Multiple regression analysis results indicate that a greater evaluation of education and the potential of individuals in the organization implies greater involvement of agricultural advisors in the selection of topics that will be provided to them through education and more advanced performances of educators responsible for educating. One-factor analysis of variance (ANOVA) determined that there are no statistically significant differences, at the p < 0.05 level, in the level of perceived competence of advisors for sustainable agricultural practices depending on the frequency of attending education.

Organizational maturity and sustainability orientation influence on DMS life cycle : case analysis
Sandra Jordan, Simona Sternad Zabukovšek, 2023, izvirni znanstveni članek

Opis: The topic of the article addresses the management of the document management system (DMS), which represents one of the important steps for organizations to speed up the implementation of business processes, achieve better control over documents, and ensure safer operations. When implementing and using DMS, the importance of the organization’s maturity shall not be forgotten, as it gives the organization a framework to evaluate and improve the overall effectiveness and efficiency of the organization’s DMS, which can contribute to better decision-making and increased productivity. On the other hand, sustainable-oriented organizations are likely to show interest in choosing, implementing, and using DMS. In the article, the impact of an organization’s maturity and the role of sustainability on the DMS lifecycle are researched. Results are presented based on a case analysis of Company X. Supporting the case analysis, structured interviews with the project leader on the clients’ and the project leader on the providers’ side have been performed, which shall give a deeper insight into DMS implementation and the importance of sustainability and organizational maturity, resulting in more successful DMS implementation and use.

Ideological differences in COVID-19 vaccine intention : the effects of trust in the healthcare system, in complementary and alternative medicine, and perceived threat from the disease
Monika Lamot, Katja Kerman, Andrej Kirbiš, 2024, izvirni znanstveni članek

Opis: Introduction: Politically left-leaning individuals are more likely to get vaccinated against COVID-19, although little is known about the mechanisms underlying the ideological differences in vaccination intentions. Understanding the extent to which trust in the healthcare system, in complementary and alternative medicine, and the perceived threat from the disease contribute to these disparities is crucial, as it could inform targeted interventions to address vaccine hesitancy across the political spectrum. Methods: The present cross-sectional study conducted among adults living in Slovenia (n  =  858) examined the mediating role of trust in the healthcare system, trust in complementary and alternative medicine (CAM), and the perceived threat from the virus on COVID-19 vaccination intention. Results: We found that leftist ideology and trust in the healthcare system positively predicted vaccination intention, whereas CAM negatively predicted this intention. In addition, left-leaning individuals expressed greater trust in the healthcare system and lower trust in CAM, resulting in higher levels of COVID-19 vaccination intention. The serial mediation model confirmed that trust in CAM was a negative predictor, while trust in the healthcare system positively predicted perceived threat. Discussion: When dealing with vaccine hesitancy among right-oriented individuals, strategies should focus on enhancing trust in the healthcare system and critically evaluating the reliance on CAM.

Multilevel analysis of COVID-19 vaccination intention : the moderating role of economic and cultural country characteristics
Monika Lamot, Andrej Kirbiš, 2024, izvirni znanstveni članek

Opis: Predictors of COVID-19 (coronavirus) vaccination have been extensively researched; however, the contextual factors contributing to understanding vaccination intention remain largely unexplored. The present study aimed to investigate the moderating role of economic development (Gross domestic product - GDP per capita), economic inequality (Gini index), the perceived corruption index and Hofstede’s measurements of cultural values—index of individualism/collectivism and power distance index—in the relationship between determinants of satisfaction with the healthcare system, trust in political institutions, conspiracy beliefs and COVID-19 vaccination intention. Methods: A multilevel modelling approach was employed on a sample of approximately 51 000 individuals nested within 26 countries. Data were drawn from the European Social Survey Round 10. The model examined the effect of individual- and country-level predictors and their interaction on vaccination intention. Results: Satisfaction with the healthcare system had a stronger positive effect on intention to get vaccinated in countries with lower perceived corruption and more individualistic countries. Trust in political institutions had a stronger positive effect on vaccination intention in countries with higher economic development and lower perceived corruption, while a negative effect of conspiracy beliefs on vaccination intention was stronger in countries with lower economic development, higher perceived corruption and a more collectivistic cultural orientation. Conclusion: Our findings highlight the importance of considering individual and contextual factors when addressing vaccination intention.

The endocannabinoid system in asthma patients and the effect of cannabinoids in the modulation of inflammatory response
Carina Esteves Pinto Kozmus, 2021, doktorska disertacija

Opis: Asthma is a chronic inflammatory condition characterised by intermittent and reversible airflow obstruction caused by inflammation, bronchospasm, and increased airway secretions. Questions about the endocannabinoid system’s function in asthma pathogenesis have arisen as evidence grows, demonstrating it is a native modulator of immune functions. The main goal of this study was to genetically characterise the endocannabinoid system in naive asthma patients and determine if there is a relationship between endogenous cannabinoids and their inflammatory response. We studied a case-control cohort of 353 patients with mild/moderate persistent asthma and 276controls. The mRNA expression levels of the selected genes were quantified in peripheral blood mononuclear cells (PBMCs) and N-acylethanolamines (NAEs) quantified from plasma samples. Our results revealed that the genes for CB1 (CNR1) andCB2 (CNR2), along with genes for the enzymes NAPE-PLD (NAPEPLD), Abhd4(ABHD4) and MAGL (MGLL) were up-regulated in asthma patients and associated with their clinical and inflammatory condition. In addition, two of the genotyped polymorphisms located in the CNR2 gene were also associated with worse clinical symptoms. Palmitoylethanolamide (PEA) levels were lower and significantly different between allergic asthma patients and the control group and associated with worse clinical symptoms. Furthermore, our findings indicate that asthma patients with highCNR1mRNA expression levels at the time of diagnosis, treated with LTA, have better treatment response, while asthma patients with highCNR1mRNA expression levels, treated with ICS, had worse treatment response. Long-term ICS or LTRA therapy reduced mRNA expression ofCNR1together withIL4andIL5.It is evident from these findings that the endocannabinoid system plays a role in asthma, but it is not possible to determine whether this up-regulation is a cause or a result of the condition. Nonetheless, our findings add to a better understanding of the endocannabinoid system’s significance in asthma pathogenesis.
