Post-war Bosnia and Herzegovina remains a society in which ethno-nationalist rhetoric and war memories permeate public discourse. This paper investigates the use of metaphors in media texts written in English and the Bosnian, Croatian, and Serbian language on the topic of ‘two schools under one roof’. Writing about this peculiar construct within the country’s educational system tackles socio-political factors and their effects on the provision of primary and second-ary education. We describe how metaphors as cognitive devices are used to portray educational developments in this post-conflict country and the effects of their use on recipients. The paper points out cases of deliberate metaphor use, which influences recipients’ perspectives on the topic at hand. Keywords: conceptual metaphor; deliberate metaphor; segregation; MIPVU.

Background and Objectives: Burden of cervical cancer in Central and Eastern Europe is higher than in other parts of Europe. We analyzed cervical cancer epidemiology in Serbia and Bosnia and Herzegovina (the Federation of Bosnia and Herzegovina and the Republic of Srpska) from January 2016 to December 2020, exploring the role of available sociodemographic factors and healthcare service parameters on incidence and mortality rates, using an ecological approach based on aggregated data. Materials and Methods: Incidence and mortality rates are standardized using the method of direct standardization with the World-ASR-W. Administrative units are grouped by tertiles of incidence and mortality to explore sociodemographic factors and healthcare parameters across these groups. Results: Average age-standardized incidence rates of cervical cancer per 100,000 females were 19.28 in Serbia, 12.48 in the Federation of Bosnia and Herzegovina, and 22.44 in the Republic of Srpska. Mortality rates per 100,000 females were 6.67, 5.22, and 4.56 in Serbia, the Federation of Bosnia and Herzegovina, and the Republic of Srpska, respectively. Several parameters of sociodemographics and health service usage differed significantly across units grouped by tertiles based on incidence level, i.e., female population ≥ 15 years old (p = 0.028), population density (p = 0.046), percent of gynecologists in the primary healthcare (p = 0.041), number of gynecologists per 10,000 females ≥ 15 years (p = 0.007), and the area-to-gynecologist ratio (p = 0.010). A moderate negative correlation was found between incidence and population density (rho = −0.465, p = 0.017), and a moderate positive correlation between incidence and area-to-gynecologist ratio (rho = 0.534, p = 0.005). Conclusions: Cervical cancer remains a leading cause of cancer among women in developing countries. Implementing tailored activities, such as educational programs, preventive services, and investments in healthcare infrastructure, particularly at the administrative units’ level, can help in reducing health disparities and improving health outcomes.

The aim of the study was to elucidate predictors associated with the initial choice of vascular access (VA) type. The secondary aim was to determine the initial VA's median utilization time and the factors governing it. This prospective cohort study included 387 hemodialysis (HD) patients admitted to the Clinic for Hemodialysis, Clinical Center University of Sarajevo, in consecutive order between January 2006 and December 2016. We selected the primary predictors for the initial VA type using a random forest algorithm. We further quantified factors governing the initial choice of VA: temporary catheters (TC), compared to arteriovenous fistula (AVF), using multivariate logistic regression. Finally, we used log-rank and Cox regression models to estimate the median time on each initial VA and find predictors governing it. Of the 387 patients, 265 (68,5%) used TC at dialysis initiation and 122 (31,5 %) AVF. Predictors of the TC's vs. AVF's initial use were older age (OR=1.02, CI=1.0, 1.03, p=0.03) and primary cause of CKD, particularly diabetes, compared to all other causes of kidney disease (CKD). Median time on initial AVF was 57.0 months (95%CI =36.9, 64.1), and on initial TC 4.99 months (95%CI =2.69, 8.48). Younger age (HR=.98,95%CI=.97, .99, p=.01), male sex (HR=1.51, 95%CI=1.05, 2.19, p=.03), and hypertension (HR=1.63, 95%CI=1.13,2.36, p=.01) predicted median time on initial TC, while older age (HR for patients>70years = 1.86, 95%CI=1.09, 3.17, p=.02), and diabetes (HR=1.97, 95%CI=1.19, 3.24, p=.01), predicted median time on initial AVF. These results point to late VA referrals and delays in transitioning to permanent VA.

Proton decay has been studied for decades now as one of the consequences of grand unified theories. Among those theories exists SU(5) theory, firstly postulated by H. Georgi and S. Glashow [1]. However, there were some problems with this theory such as mass degeneration and coupling unification [1-3]. This created a need for an extension of an original SU(5) model – a specific minimal SU(5) [4-5]. In this minimal SU(5) there is a viable parameter space with achievable gauge coupling unification. In this article, we present the process of gauge coupling unification for three mass scales of new physics states in this model, namely for 1 TeV, 10 TeV, and 100 TeV.

Abstract Serpentine soils are characterized as a unique environment with low nutrient availability and high heavy metal concentrations, often hostile to many plant species. Even though these unfavorable conditions hinder the growth of various plants, particular vegetation with different adaptive mechanisms thrives undisturbed. One of the main contributors to serpentine adaptation represents serpentine bacteria with plant growth-promoting properties that assemble delicate interactions with serpentine plants. Robinia pseudoacacia L. is an invasive but adaptive species with phytoremediation potential and demonstrates extraordinary success in this environment. To explore more in-depth the role of plant growth-promoting serpentine bacteria, we isolated them and tested their various plant growth-promoting traits both from the rhizosphere and roots of R. pseudoacacia. Based on the demonstrated plant growth-promoting traits such as siderophore production, phosphate solubilization, nitrogen fixation, indole-3-acetic acid production, and ACC deaminase production, we sequenced overall 25 isolates, 14 from the rhizosphere and 11 from the roots. Although more efficient in exhibiting plant growthpromoting traits, rhizospheric bacteria showed a low rate of diversity in comparison to endophytic bacteria. The majority of the isolates from the rhizosphere belong to Pseudomonas, while isolates from the roots exhibited higher diversity with genera Pseudomonas, Bacillus, Staphylococcus, Lysinibacillus and Brevibacterium/Peribacillus/Bacillus. The capacity of the described bacteria to produce siderophores, solubilize phosphate, and fix nitrogen highlights their central role in enhancing nutrient availability and facilitating R. pseudoacacia adaptation to serpentine soils. The findings highlight the potential significance of serpentine bacteria, particularly Pseudomonas, in contributing to the resilience and growth of R. pseudoacacia in serpentine environments.

In this study, we compared the effectiveness of AR-based homework, traditional homework, and mixed-approach homework in learning about circular motion. To that end, we conducted a pretest-posttest quasi-experiment involving 135 first-year students enrolled in an introductory physics course at the University of Zagreb, Faculty of Chemical Engineering and Technology, Croatia. The students in the experimental group completed augmented reality (AR)-based homework assignments. In these assignments, their learning about circular motion was supported by a meticulously designed worksheet that included four AR-supported activities. In the mixed-approach group, students were given a homework assignment that included three AR-supported activities and one quantitative textbook problem, whereas the traditional group’s homework consisted of four quantitative textbook problems covering the same content. Findings from our study suggest that the post-treatment scores for all groups were significantly higher than the pretreatment scores, with the largest pre-post gains observed in the mixed-approach group. We conclude that combining carefully selected quantitative problems with key AR activities is the most promising approach.

The aim of the research was to determine the psychometric properties of the Multidimensional Scale of Perceived Social Support in individuals with disabilities in Bosnia and Herzegovina. The research included a total sample of 232 participants, with an average chronological age of 44.21±19.31 years, of which 121 (52.2%) were male and 111 (47.8%) were female. The study was conducted among individuals with motor impairments, visual and hearing impairments, speech and language disorders, and combined disabilities. To achieve the research objective, the Multidimensional Scale of Perceived Social Support was applied, consisting of 12 assessment variables scaled from 1 to 7. The research data were processed using parametric and non-parametric statistical methods. A multivariate method of exploratory factor analysis was applied to identify factors in a given domain when the number and structure of factors are not previously known, along with confirmatory factor analysis using the maximum likelihood algorithm. Following factorization, the internal consistency coefficient (Cronbach's alpha) was calculated, and the reliability of the variables was assessed through inter-item statistics. Based on the obtained research results, it can be concluded that the Multidimensional Scale of Perceived Social Support has satisfactory reliability and internal consistency for use among individuals with disabilities in Bosnia and Herzegovina. The results of both exploratory and confirmatory factor analysis indicate a suitable three-dimensional model and confirm the original structure of the scale, which can be applied to individuals with disabilities in Bosnia and Herzegovina. Keywords: Social support, disability, validity, reliability, factor analysis.

Leisure time in contemporary society is increasingly becoming a crucial factor in shaping the personalities of children and youth. Alongside family, schools play a central role in organizing and shaping students' leisure time. The aim of this paper is to examine the role of schools in the pedagogical structuring of students’ leisure time and to explore differences in the perception of leisure time between students in urban and rural schools. The research was conducted on a sample of 140 seventh-grade students from elementary schools in the Tuzla Canton. The study analyzed students' ways of spending leisure time, the involvement and support of schools in organizing leisure time, and the perception of societal support for students' leisure activities. The results of the research indicate that students most frequently spend their leisure time in activities without significant pedagogical influence. Most students occasionally participate in school clubs, with significant differences observed between urban and rural schools in the type and number of activities available. Teachers and parents are the primary sources of support in organizing leisure time, while the broader community offers limited support. The findings suggest that schools play an important role in the organization of leisure time but that there are significant disparities in the activities available to students in different environments. Although activities such as sports and cultural clubs remain popular, students are increasingly gravitating towarddigital content, which may reduce the pedagogical value of leisure time. Schools should continue to develop and adapt leisure activities to meet students’ needs, with greater involvement from the broader community and support in fostering healthy and constructive patterns of leisure time usage. Keywords:school, children, education, leisure time.

Abstract Current literature on the privacy paradox in personalised advertising lacks insight into how consumers’ knowledge of the data types used shapes their responses to these ads. Building on privacy calculus theory, theory of reasoned action, and signalling theory, this research explores how consumers’ knowledge of data types in personalised advertising influences their reactions. Multigroup path analysis examines differences in established relationships based on consumers’ data knowledge. The moderating effect of this knowledge in the relationship between perceived invasiveness and purchase intentions is also tested. Findings from a sample of millennials indicate that privacy concerns increase perceived invasiveness. However, multigroup and moderation analyses reveal that perceived invasiveness’ impact on purchase intentions varies with consumers’ data knowledge. Specifically, in the search history group, perceived intrusiveness negatively affects purchase intentions. These results underscore the situation-specific nature of the privacy calculus and assist advertisers in understanding consumer behaviour in response to personalised ads.

This paper deals with the problem of the relationship between young people's life satisfaction and their material condition, locus of control, attitude towards studying, attitude towards work and life orientation. The concept of life satisfaction and other correlates mentioned in the paper are certainly current in psychology and have been increasingly researched lately. It is very important to investigate the life satisfaction of young people and other correlates that contribute to life satisfaction, and to observe them all together through the prism of positive psychology. In this paper, we investigated what kind of relationships exist between the life satisfaction of young people and their material condition, their locus of control, attitude towards studies and work, and life orientation. Appropriate measuring instruments were applied to a sample of N=260 respondents (M=1.63, SD=.482). A scale for assessing life satisfaction, a scale for testing locus of control, a scale for attitudes towards studying, a scale for attitudes towards work and a life orientation scale, as well as a questionnaire for collecting appropriate sociodemographic characteristics. The scales that were used in the research showed appropriate metric characteristics of 0.87 for life satisfaction and locus of control, 0.78 for attitude towards studying, while slightly lower values for attitude towards work were 0.48 and life orientation 0.49. .The results of the research showed that there is a statistically significant positive correlation between life satisfaction of young people and satisfactory material condition (r=0.316, p=0.00) and between life satisfaction and locus of control (r=0.208, p=0.001). However, there is no statistically significant correlation between young people's life satisfaction and attitudes towards studying (r=0.107, p=0.091). As for the life satisfaction of young people and attitude towards work, there is a negative correlation between these variables (r=-0.201, p=0.001) and there is a positive correlation between life satisfaction and life orientation (r=0.456, p=0.000).
