A game theoretical model for the stimulation of public cooperation in environmental collaborative governance
Yinhai Fang, Matjaž Perc, Hui Zhang, 2022, original scientific article

Abstract: 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, original scientific article

Abstract: 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, original scientific article

Abstract: 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, original scientific article

Abstract: 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.

Common and specific large-scale brain changes in major depressive disorder, anxiety disorders, and chronic pain : a transdiagnostic multimodal meta-analysis of structural and functional MRI studies
Felix Brandl, Benedikt Weise, Satja Mulej Bratec, Nazia Jassim, Daniel Hoffmann Ayala, Teresa Bertram, Markus Ploner, Christian Sorg, 2022, original scientific article

Abstract: Major depressive disorder (MDD), anxiety disorders (ANX), and chronic pain (CP) are closely-related disorders with both high degrees of comorbidity among them and shared risk factors. Considering this multi-level overlap, but also the distinct phenotypes of the disorders, we hypothesized both common and disorder-specific changes of large-scale brain systems, which mediate neural mechanisms and impaired behavioral traits, in MDD, ANX, and CP. To identify such common and disorder-specific brain changes, we conducted a transdiagnostic, multimodal meta-analysis of structural and functional MRI-studies investigating changes of gray matter volume (GMV) and intrinsic functional connectivity (iFC) of large-scale intrinsic brain networks across MDD, ANX, and CP. The study was preregistered at PROSPERO (CRD42019119709). 320 studies comprising 10,931 patients and 11,135 healthy controls were included. Across disorders, common changes focused on GMV-decrease in insular and medial-prefrontal cortices, located mainly within the so-called default-mode and salience networks. Disorder-specific changes comprised hyperconnectivity between defaultmode and frontoparietal networks and hypoconnectivity between limbic and salience networks in MDD; limbic network hyperconnectivity and GMV-decrease in insular and medial-temporal cortices in ANX; and hypoconnectivity between salience and default-mode networks and GMV-increase in medial temporal lobes in CP. Common changes suggested a neural correlate for comorbidity and possibly shared neuro-behavioral chronification mechanisms. Disorder-specific changes might underlie distinct phenotypes and possibly additional disorder-specific mechanisms.

Varieties of 'rationality' and the question of their continued theoretical relevance
Tibor Rutar, 2020, original scientific article

Abstract: The notion of 'rationality' has always been one of the more controversial social-scientific ideas. Today there exist many conceptual varieties of rationality which are often less than clearly distinguished and the precise intellectual import of which likewise tends to be opaque. In this article I draw on classical and contemporary examples from sociology, political science and economics in the effort to clarify the many meanings of the notion and to demonstrate that it is more useful as well as more legitimate for explanatory purposes than some canonical critiques suggest. As the behavioral economics revolution has made clear, many varieties of rationality are both empirically and theoretically limited or outright falsified. However, although it is now certain that rationality cannot be the singular basis of a universal, general theory of social behavior, I argue it can and should form one important part of a larger conceptual toolbox upon which a social theorist can draw when devising tractable theoretical explanations of social phenomena.

Self-protective behaviour among young adults during public health crisis
Luka Jelovčan, Kaja Prislan Mihelič, Anže Mihelič, 2020, original scientific article

Abstract: Purpose: The purpose of this article is to examine perceptions of factors deriving from the theory of planned behaviour among younger adults in times of public health crisis, their self-protective behaviour compared to other age groups, and test the predictive factors according to the theory of planned behaviour. Design/Methods/Approach: An online survey has been conducted to examine self-protective behaviour in times of public health crisis. The survey was distributed to Slovenian citizens (n = 280) using the social network Facebook. Descriptive statistics were used to describe the sample and measured variables. Multiple regression analysis was conducted to determine associations between identified factors. Findings: The results of the study indicate that there are no significant differences in self-reported self-protection between younger adults and others. Additionally, attitude toward self-protective measures is the most important predictor of self-protective behaviour for both age groups. Only the attitude is significantly associated with self-protective behaviour among young adults, whereas among others, all three predictors are significantly associated with self-protective behaviour, explaining nearly twice the variance. Research Limitations/Implications: This research contributes to the understanding of motivators that drive individuals to engage in self-protective behaviour in times of health crises. It provides insight into young adults' self-protective behaviour. Most of the limitations are related to the sample, which only contains respondents from one social network and one country. Originality/Value: To the best of our knowledge, this is the first study that explored the self-protective behaviour of young adults during COVID-19 using the theory of planned behaviour and compares the differences in self-protective behaviour predictors among different age groups.

Safety issues in psychiatric settings
Tinkara Pavšič Mrevlje, Peter Umek, 2011, review article

Abstract: Purpose: The purpose of the paper is to establish if mental health workers (nurses, doctors, clinical psychologists) in Slovene psychiatric settings perceive their work as potentially dangerous and which factors contribute mostly to these mindsets. On the basis of gained data recommendations for safety improvement are suggested. Design/Methods/Approach: Review of three studies conducted in different psychiatric settings in Slovenia. Findings: Just a few mental health workers perceive their work as dangerous. Among those that are most frequently victims of violent behaviour are male and female nurses, especially under circumstances of involuntary admission, involuntary pharmacological treatment and when special security measures are applied. Participants think that workers would need more self defence trainings, additional competent medical staff (foremost male nurses), communication trainings and better cooperation in their working teams. Moreover, those hurt in such incidents should get more systematic help. Sometimes security personnel also intervene, however, they are not qualified for such interventions and special trainings should be provided. Research limitations/implications: Our findings have a limited value because the studies have been performed in the course of different years, different questionnaires were applied and participants also differed (their profession, working tasks, demographic data etc.). Practical implications: Our findings can be used by psychiatric hospital management to plan trainings for mental health workers and organize them according to personnel’s necessities. Results also imply the necessity to train security personnel. Originality/Value: In the past merely analyses of incident reports were made on this topic. However, this paper sheds some light on perceptions and experiences of mental health workers directly exposed to patients’ violent behaviour.

A comparison of linear and nonlinear seismic tunnel-ground interaction analyses
Elefterija Zlatanović, Marina Trajković-Milenković, Dragan Lukić, Stanko Brčić, Vlatko Šešov, 2016, original scientific article

Abstract: In order to study the effects of a seismically induced tunnel–ground interaction, two-dimensional numerical analyses are performed using the sofware ANSYS. The study employs a coupled beam–spring model subjected to earthquake loading that is simulated under pure shear conditions and determined by a free-field ground-response analysis using the code EERA. The properties of the soil material are considered as both linear and nonlinear. The results obtained by linear dynamic analyses are compared with state-of-practice analytical elastic solutions. A comparison of the results of both linear and nonlinear analyses is also performed, and significant differences, as well as important factors influencing the tunnel–ground interaction for both cases, are evaluated.
Keywords: circular tunnel, linear/nonlinear soil behaviour, beam–spring model, plane-strain conditions, simplified dynamic FE analysis, soil–structure interaction

Time-dependent behaviour of reinforced cuts in weathered flysch rock masses
Mirko Grošić, Željko Arbanas, 2014, original scientific article

Abstract: Knowledge of stress-strain rock mass behaviour is crucial for many engineering purposes. Rock mass deformations and their influences on construction are observed during construction and even during exploitation phases. These deformations in the exploitation phase are caused by the time-dependent behaviour of the rock mass. A flysch rock mass is categorised as a heterogenic weak rock that has been intensely subjected to weathering processes. Due to weathering processes, the flysch rock mass degrades from fresh rock to residual soil within only a few meters of the geological profile below the surface. Observations of reinforced cuts along the Adriatic motorway near the City of Rijeka, Croatia, were conducted over a time period of seven years of spanning construction and exploitation. Measured displacements reached significant magnitudes during the exploitation period as a consequence of the time-dependent behaviour of the rock mass. The paper presents findings related to flysch rock mass weathering profile and its characteristics based on detailed geotechnical investigations and monitoring results coupled with back analyses. It was found possible to detect the thickness of the flysch rock mass weathering profile by performing detailed geotechnical investigations. Recommendations for the strength, deformation, and creep properties of the weathering profile of a flysch rock mass are given.
