Analysis of seed-associated bacteria and fungi on staple crops using the cultivation and metagenomic approaches
Valerija Tkalec, Aleksander Mahnič, Peter Gselman, Maja Rupnik, 2022, izvirni znanstveni članek

Opis: One of the key factors afecting seed quality is microbial communities residing on and in the seeds. In this study, microbial populations of seeds of conventionally and organically produced wheat, barley, and maize were analyzed using two diferent approaches: the cultivation method and metagenomics. For cultivation, three basic media were used: DG18 (for fungi), and nutrient agar or tryptic soy agar supplemented with cycloheximide or nystatin (for bacteria). Metagenomic sequencing was performed using the Illumina MiSeq platform. A total of 452 bacterial isolates comprising 36 genera and 5 phyla and 90 fungal isolates comprising 10 genera and 3 phyla were obtained from the seed surfaces. Among bacteria, representatives from the genera Bacillus, Pantoea, Paenibacillus, and Curtobacterium predominated, and among fungi, Aspergillus predominated. A total of 142 fungal OTUs and 201 bacterial OTUs were obtained from all the samples. Proteobacteria, Firmicutes, Bacteroides, and Actinobacteria comprised most of the bacterial OTUs, and Ascomycota comprised most of the fungal OTUs. Only 3 fungal OTUs (representatives of Curvibasidium, Venturia, and Dermateaceae) were exclusively present only within seeds and not on the seed surfaces. Barley seeds had the highest microbial load and richness, whereas corn had the lowest. Wheat and barley shared a higher number of OTUs than either of them did with corn with higher overlap between conventionally grown cereals than between organically grown cereals. Some OTUs were farming specifc. This study demonstrates that the microbiome of cereal seeds is greatly dependent on the species of the host and is less afected by agricultural practices.

Safety culture and the positive association of being a primary care training practice during COVID-19 : the results of the multi-country European PRICOV-19 study
Bianca Silva, Zlata Ožvačić Adžić, Pierre Vanden Bussche, Esther Van Poel, Bohumil Seifert, Cindy Heaster, Claire Collins, Canan Tuz Yilmaz, Felicity Knights, Zalika Klemenc-Ketiš, 2022, izvirni znanstveni članek

Opis: The day-to-day work of primary care (PC) was substantially changed by the COVID-19 pandemic. Teaching practices needed to adapt both clinical work and teaching in a way that enabled the teaching process to continue, while maintaining safe and high-quality care. Our study aims to investigate the effect of being a training practice on a number of different outcomes related to the safety culture of PC practices. PRICOV-19 is a multi-country cross-sectional study that researches how PC practices were organized in 38 countries during the pandemic. Data was collected from November 2020 to December 2021. We categorized practices into training and non-training and selected outcomes relating to safety culture: safe practice management, community outreach, professional well-being and adherence to protocols. Mixed-effects regression models were built to analyze the effect of being a training practice for each of the outcomes, while controlling for relevant confounders. Of the participating practices, 2886 (56%) were non-training practices and 2272 (44%) were training practices. Being a training practice was significantly associated with a lower risk for adverse mental health events (OR: 0.83; CI: 0.70-0.99), a higher number of safety measures related to patient flow (Beta: 0.17; CI: 0.07-0.28), a higher number of safety incidents reported (RR: 1.12; CI: 1.06-1.19) and more protected time for meetings (Beta: 0.08; CI: 0.01-0.15). No significant associations were found for outreach initiatives, availability of triage information, use of a phone protocol or infection prevention measures and equipment availability. Training practices were found to have a stronger safety culture than non-training practices. These results have important policy implications, since involving more PC practices in education may be an effective way to improve quality and safety in general practice.

Logistics aspect of organizational culture and normative commitment in electric energy supply chain
Sebastjan Lazar, Vojko Potočan, Sonja Mlaker Kač, Gözde Yanginlar, Dorota Klimecka-Tatar, Matevž Obrecht, 2022, izvirni znanstveni članek

Opis: Companies are increasingly aware that employees are an important factor in success, so they pay more and more attention to them. Because of that, organizational culture and normative commitment are also included as ex-tremely important factors. The research includes a systematic and comprehensive review of the literature and at the same time obtaining and analysing data from practice through a survey. The research focuses on employees from the logistics departments in the supply chain of electronic component production and supply. Group of com-panies across Europe were included in the survey (Austria, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Re-public, Germany, Hungary, Latvia, Lithuania, North Macedonia, Poland, Romania, Russia, Serbia, Slovenia and Ukraine). The research demonstrates the realization that the types of classification of organizational culture have different effects on direct and indirect normative commitment. Gender differences were also found. The re-search-based on the calculated average mean values shows the classifications of organizational culture and nor-mative commitment. The latter follows the organizational culture with minor deviations. The order of classifica-tion of organizational culture follows the current economic situation, where according to the studied criteria, the first is a culture of the market. The research shows that men’s rate of normative commitment is better than wom-en's, while in organizational culture the situation is exactly the opposite. One of the most significant findings is based on the Pearson correlation coefficient with the SPSS program was found that, according to the classifica-tion, Hierarchy culture has a positive effect on indirect normative commitment.

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.

Maximizing employee engagement through artificial intelligent organizational culture in the context of leadership and training of employees : testing linear and non-linear relationships
Maja Rožman, Polona Tominc, Borut Milfelner, 2023, izvirni znanstveni članek

Opis: The paper’s main aim is to analyze five constructs of organizational culture, AI-supported leadership, AI-supported appropriate training of employees, teams’ effective performance, and employee engagement, and their relationship through the prism of artificial intelligence on a sample of large and medium-sized Slovenian companies. The second aim of the paper is to test the proposed model with two different statistical techniques in the scope of structural equation modeling (SEM) that enable us to assess linear (PLS-SEM) and non-linear relationships (CB-SEM) among the constructs. The empirical research included 437 medium-sized and large Slovenian companies. From each company, a CEO or owner participated in our research. The findings of the research with both techniques show that organizational culture had no impact on AI-supported appropriate training of employees and was not significant as well as that organizational culture had an impact on AI-supported leadership. The impact of AI-supported leadership on AI-supported appropriate training of employees were supported only for the PLS-SEM model. The impact of AI-supported leadership for employees on teams was positive. Contrary to that, the impact of AI-supported leadership for business solutions on teams was non-significant. In both cases, AI-supported appropriate training of employees’ impact on teams was strong and positive. Also, employee engagement impact on teams was positive and statistically significant with PLS-SEM and CB-SEM methods. The research yields important implications for companies seeking to integrate artificial intelligence effectively in their operations. It emphasizes the critical role of AI-supported leadership in driving positive outcomes, such as improved employee training and enhanced team effectiveness. Companies should focus on developing leaders who can leverage AI tools to foster a skilled and engaged workforce. By adopting data-driven decision-making processes and incorporating insights from structural equation modeling, organizations can develop effective AI integration strategies. These provide valuable guidance for enhancing human resource management practices and achieving successful AI adoption across companies. The findings contribute to the formation of new views in the field of artificial intelligence implementation in the companies and show companies a broader picture of which aspects of human resource management need to be improved.

Sensitivity to imidacloprid insecticide varies among some social and solitary bee species of agricultural value
Blair Sampson, Aleš Gregorc, Mohamed Alburaki, Chris Werle, Shahid Karim, John Adamczyk, Patricia R. Knight, 2023, izvirni znanstveni članek

Opis: Pollinator health risks from long-lasting neonicotinoid insecticides like imidacloprid has primarily focused on commercially managed, cavity-nesting bees in the genera Apis, Bombus, and Osmia. We expand these assessments to include 12 species of native and non-native crop pollinators of differing levels of body size, sociality, and floral specialization. Bees were collected throughout 2016 and 2017 from flowering blueberry, squash, pumpkin, sunflower and okra in south Mississippi, USA. Within 30–60 minutes of capture, bees were installed in bioassay cages made from transparent plastic cups and dark amber jars. Bees were fed via dental wicks saturated with 27% (1.25 M) sugar syrup containing a realistic range of sublethal concentrations of imidacloprid (0, 5, 20, or 100 ppb) that are often found in nectar. Bees displayed no visible tremors or convulsions except for a small sweat bee, Halictus ligatus, and only at 100ppb syrup. Imidacloprid shortened the captive longevities of the solitary bees. Tolerant bee species lived ~10 to 12 days in the bioassays and included two social and one solitary species: Halictus ligatus, Apis mellifera and Ptilothrix bombiformis (rose mallow bees), respectively. No other bee species tolerated imidacloprid as well as honey bees did, which exhibited no appreciable mortality and only modest paralysis across concentration. In contrast, native bees either lived shorter lives, experienced longer paralysis, or endured both. Overall, longevity decreased with concentration linearly for social bees and non-linearly for solitary species. The percentage of a bee’s captive lifespan spent paralyzed increased logarithmically with concentration for all species, although bumble bees suffered longest. Of greatest concern was comparable debilitation of agriculturally valuable solitary bees at both low and high sublethal rates of imidacloprid.

Safety culture in the operating room : translation, validation of the safety attitudes questionnaire - operating room version
Teodor Pevec, Tit Albreht, Eva Turk, 2023, izvirni znanstveni članek

Opis: Background: Measuring the safety culture in Healthcare is an important step in improving patient safety. One of the most commonly used instruments to measure the safety climate is the Safety Attitudes Questionnaire (SAQ). The aim of the current study was to establish the validity and reliability of the Slovenian version of the SAQ for the operating room SAQ-OR. Methods: The SAQ, consisting of six dimensions, was translated and adapted to the Slovenian context and applied in operating rooms from seven out of ten Slovenian regional hospitals. Cronbach's alpha and confirmatory factor analysis (CFA) was used to evaluate the reliability and validity of the instrument. Results: The sample consisted of 243 health care professionals who hold positions in the OR, divided into 4 distinct professional classes, namely, 76 surgeons (31%), 15 anesthesiologists (6%), 140 nurses (58%) and 12 auxiliary persons (5%). It was observed a very good Cronbach's alpha (0.77 to 0.88). The CFA and its goodness-of-fit indices (CFI 0.912, TLI 0.900, RMSE 0.056, SRMR 0.056) showed an acceptable model fit. There are 28 items in the final model. Conclusions: The Slovenian version of the SAQ-OR revealed good psychometric properties for studying the organisational safety culture.

Slow tourism in the post-Covid era : the case of Montenegro
Ivona Jovanović, Jasna Potočnik Topler, 2022, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Opis: This chapter explores slow tourism as a sustainable tourism concept with the potential for slow tourism offers in Montenegro. Namely, the post-Covid tourist faces an accelerated pace of life and often a stressful daily routine. They need relaxation and a vacation that cannot be found in the tourist offers containing lots of sightseeing tours in as short a time as possible. Accordingly, a new concept of travel has been developing in recent years, especially after the Covid-19 pandemic, one which promotes relaxation and "deep" exploration of the tourist destination - slow tourism. The slow tourist is usually not attracted to the established routes and ready tourist products. Instead, the focus is placed on traveling to the destination, using slow means of transportation, as well as on avoiding large hotels. Slow tourists are trying to get to know the local culture and establish contacts with the locals. Montenegro enables all that.
