Analysing flexural response in RC beams: a closed-form solution designer perspective from detailed to simplified modelling
Denis Imamović, Matjaž Skrinar, 2024, izvirni znanstveni članek

Opis: This paper presents a detailed analytical approach for the bending analysis of reinforced concrete beams, integrating both structural mechanics principles and Eurocode 2 provisions. The general analytical expressions derived for the curvature were applied for the transverse displacement analysis of a simply supported reinforced concrete beam under four-point loading, focusing on key limit states: the initiation of cracking, the yielding of tensile reinforcement and the compressive failure of concrete. The displacement’s results were validated through experimental testing, showing a high degree of accuracy in the elastic and crack propagation phases. Deviations in the yielding phase were attributed to the conservative material assumptions within the Eurocode 2 framework, though the analytical model remained reliable overall. To streamline the computational process for more complex structures, a simplified model utilising a non-linear rotational spring was further developed. This model effectively captures the influence of cracking with significantly reduced computational effort, making it suitable for serviceability limit state analyses in complex loading scenarios, such as seismic impacts. The results demonstrate that combining detailed analytical methods with this simplified model provides an efficient and practical solution for the analysis of reinforced concrete beams, balancing precision with computational efficiency.

Sustainable synergy: unveiling the symbiotic relationship between personal lifestyles and corporate sustainable business practices
Matevž Obrecht, Tina Cvahte Ojsteršek, Lazar Pavić, 2024, izvirni znanstveni članek

Opis: This study, conducted among 596 employees across various industries, investigates the interplay between personal sustainable lifestyle scores and corporate sustainable business practices, including energy consumption and renewable energy use. The research reveals a strong correlation between individuals’ personal sustainable lifestyles and their organisations’ sustainable business practices. Notably, employees consistently practising personal sustainable behaviours, including energy efficiency, tend to work in companies with robust sustainability initiatives and low-carbon strategies. Women, in particular, displayed higher engagement in sustainable behaviours. Age-related trends suggest younger employees prioritise corporate sustainability policies more than older counterparts, who focus more on personal sustainable behaviour. Among all studied sectors the production sector stands out for its high sustainable lifestyle and sustainable business practices, reflecting the impact of industry-specific sustainability trends like lean and green operations. On the one hand, sustainable lifestyle involves making choices and taking actions that enable rational consumption of goods and products, protecting natural resources, using renewable energy sources, and utilising low-emission transport means. These findings underscore the critical link between personal sustainability habits and organisational sustainability business practices, highlighting a significant avenue for promoting sustainability and reduced energy consumption in the workplace and at home

Cross-sectional personal network analysis of adult smoking in rural areas
Bianca-Elena Mihǎilǎ, Marian-Gabriel Hâncean, Matjaž Perc, Jürgen Lerner, Iulian Oană, Marius Geanta, José Luis Molina González, Cosmina Cioroboiu, 2024, izvirni znanstveni članek

Opis: Research on smoking behaviour has primarily focused on adolescents, with less attention given to middle-aged and older adults in rural settings. This study examines the influence of personal networks and sociodemographic factors on smoking behaviour in a rural Romanian community. We analysed data from 76 participants, collected through face-to-face interviews, including smoking status (non-smokers, current and former smokers), social ties and demographic details. Multilevel regression models were used to predict smoking status. The results indicate that social networks are essential in shaping smoking habits. Current smokers were more likely to have smoking family members, reinforcing smoking within familial networks, while non-smokers were typically embedded in non-smoking environments. Gender and age patterns show that women were less likely to smoke, and older adults were more likely to have quit smoking. These findings suggest that targeted interventions should focus not only on individuals but also on their social networks. In rural areas, family-based approaches may be particularly effective due to the strong influence of familial ties. Additionally, encouraging connections with non-smokers and former smokers could help disrupt smoking clusters, supporting smoking cessation efforts.

Strength of culture and transfer of knowledge in organizations
Nataša Pivec, Vojko Potočan, 2021, izvirni znanstveni članek

Opis: This paper analyses the effects of organizational culture on the transfer of knowledge in organizations. While prior literature has considered relations between individual classifications of organizational culture and the whole process of knowledge development, we focused our analysis on the dimension of cultural strength and its effects on the selected phase of knowledge transfer in organizations. Our study suggested that organizations need to analyse how weak and strong organizational culture affects knowledge in organizations. The study drew upon the behavioural, organizational, and knowledge management theories and analysed answers from 138 respondents in Slovenian organizations. Analysing knowledge data demonstrates that older respondents and employees in managerial positions are more prone to knowledge transfer. The analysis shows that the strength of organizational culture is positively and statistically significantly associated with knowledge transfer in organizations. The main practical implication of this study is our finding, which suggests that organizations need to further improve the transfer of knowledge through increasing the strength of organizational culture.

Teaching strategies for promoting motor creativity and motor skill proficiency in early childhood
Miha Marinšek, Nina Lukman, 2022, izvirni znanstveni članek

Opis: Existing research provides ambiguous evidence for associations between motor competency and motor creativity. Therefore, this study examined the association between motor skill proficiency and motor creativity. The Test of Gross Motor Development (second edition) and Bertsch's motor creativity test were used to assess motor skill proficiency and motor creativity among 39 children aged five to six. Results revealed that motor proficiency and motor creativity are not interrelated traits. Therefore, it is necessary to use different teaching strategies to promote these traits. Teaching with direct instructions and reproduction of demonstrated movement is probably the most appropriate to acquaint children with motor skills. Learning through play with less explicit teaching instructions and emphasis on motivating children to find novel and original solutions to the motor tasks is probably more suitable for facilitating motor creativity.

COVID-19 and social distancing : ǂa ǂcross-cultural study of interpersonal distance preferences and touch behaviors before and during the pandemic
Ilona Croy, Andreja Avsec, Tina Kavčič, Bojan Musil, Nejc Plohl, Gaja Zager Kocjan, Maja Zupančič, 2024, izvirni znanstveni članek

Opis: The COVID-19 pandemic has led to the introduction of unprecedented safety measures, one of them being physical distancing recommendations. Here, we assessed whether the pandemic has led to long-term effects on two important physical distancing aspects, namely interpersonal distance preferences and interpersonal touch behaviors. We analyzed nearly 14,000 individual cases from two large, cross-cultural surveys – the first conducted 2 years prior to the pandemic and the second during a relatively stable period of a decreased infection rate in May-June 2021. Preferred interpersonal distances increased by 54% globally during the COVID-19 pandemic. This increase was observable across all types of relationships, all countries, and was more pronounced in individuals with higher self-reported vulnerability to diseases. Unexpectedly, participants reported a higher incidence of interpersonal touch behaviors during than before the pandemic. We discuss our results in the context of prosocial and self-protection motivations that potentially promote different social behaviors.

A game theoretical model for the stimulation of public cooperation in environmental collaborative governance
Yinhai Fang, Matjaž Perc, Hui Zhang, 2022, izvirni znanstveni članek

Opis: Digital technologies provide a convenient way for the public to participate in environmental governance. Therefore, by means of a two-stage evolutionary model, a new mechanism for promoting public cooperation is proposed to accomplish environmental collaborative governance. Interactive effects of government-enterprise environmental governance are firstly explored, which is the external atmosphere for public behaviour. Second, the evolutionary dynamics of public behaviour is analysed to reveal the internal mechanism of the emergence of public cooperation in environmental collaborative governance projects. Simulations reveal that the interaction of resource elements between government and enterprise is an important basis for environmental governance performance, and that governments can improve this as well as public cooperation by increasing the marginal governance propensity. Similarly, an increase in the government's fixed expenditure item of environmental governance can also significantly improve government-enterprise performance and public cooperation. And finally, the effect of government's marginal incentive propensity on public environmental governance is moderated by enterprises' marginal environmental governance propensity, so that simply increasing the government's marginal incentive propensity cannot improve the evolutionary stable state of public behaviour under the scenario where enterprises’ marginal environmental governance propensity is low.

Understanding, trusting, and applying scientific insights to improve your health : a latent profile analysis approach
Nejc Plohl, Bojan Musil, 2022, izvirni znanstveni članek

Opis: Various leading causes of death can be prevented or delayed through informed decision-making and lifestyle changes. Previous work has, to some extent, linked such health-promoting behavior (HPB) with variables capturing individuals’ understanding of science, trust in science, and capacity to apply evidence-based information in the health context. However, empirical research on the relationship between scientific knowledge, trust in science, health literacy, and HPB is scarce. Additionally, no study has investigated whether these characteristics interact to form homogeneous, high-risk subgroups of the population. The present online study (N = 705) revealed that trust in science and health literacy were positively related to a wide array of HPBs (e. g., healthy nutrition, physical activity, stress management), while scientific knowledge was only positively associated with COVID-19 vaccination intention. Furthermore, the results of latent profile analyses yielded four subgroups (i. e., low, moderate, and high levels of all three variables and a varied profile exhibiting very low trust in science, low health literacy, and moderate scientific knowledge). The identified subgroups differ significantly in HPB and variables determining profile membership (e. g., political conservatism). Hence, the present study offers some guidance on which groups may be targeted with public health campaigns and how they may be designed.

Microstructure, mechanical properties and fatigue behaviour of a new high-strength aluminium alloy AA 6086
Franc Zupanič, Jernej Klemenc, Matej Steinacher, Srečko Glodež, 2023, izvirni znanstveni članek

Opis: This study presents the comprehensive experimental investigation of the microstructure, mechanical and fatigue properties of a new high-strength aluminium alloy AA 6086, which was developed from a commercial aluminium alloy AA 6082. The new alloy possesses a higher content of Si, and, it also contains Cu and Zr. The alloy was characterised in the as-cast condition after homogenisation, extrusion, and T6 heat treatment. Light microscopy, scanning and transmission electron microscopy with energy dispersive spectrometry were used to analyse the microstructure and the fractography of broken specimens. The quasi-static and fatigue tests were performed on the MTS Landmark 100 kN servo-hydraulic test machine, controlled with a mechanical extensometer with a 25 mm gauge length. The quasi-static strength of the analysed aluminium alloy AA 6086 was found to be significantly higher if compared to some other AA 6xxx alloys, while the ductility was kept almost the same. The experimental results of the comprehensive fatigue tests in a Low Cycle Fatigue (LCF) and High Cycle Fatigue (HCF) regime showed a good fatigue resistance, and represent a good basis for engineering design applications of the newly developed aluminium alloy AA 6086.

Erasmus+ mobility : empirical insights into Erasmus+ tourists' behaviour
Miha Lesjak, Emil Juvan, Eva Podovšovnik, 2020, izvirni znanstveni članek

Opis: Erasmus+ students represent a large sub-segment of educational tourists, making this segment an attractive market for universities as well as destination marketing organisations. Unfortunately, very little is known about Erasmus+ students' travel behaviour; hence the present study aims at extending empirically supported knowledge about travel behaviour of students during their Erasmus+ mobility. Data was collected via an online survey among all Erasmus+ enrolling students in the academic year 2016/17 in Slovenia. The results show that 93% of the participants travelled during theirmobility. The level of studies aswell as gender affect students' travel behaviour, making the two characteristics immediately useful attributes when targeting Erasmus+ travellers. Based on perceived destination attributes, male students predominantly seek cities with attractive nightlife but female students look for easily accessible cities, which are safe and offer attractive cultural sites. These findings suggest that tourism providers, destination tourism organisations and universities should work hand in hand when designing personalised tourism experiences and their promotion among Erasmus+ students. This is crucial during the phase of planning Erasmus+ mobility, when students choose their destination and host university, as well as during students' Erasmus+ mobility, because Erasmus + students travel during their student mobility.
