Analysis of Higher Education Indicators Coherency in Central and Eastern Europe
Background: Higher education has the main role in generating innovative activity in knowledge-based economies. Therefore, the efficiency of the higher education sector reflects the alignment of the higher education policy with government expenditure. However, countries in Central and Eastern Europe (CEE region) have been struggling with national budget optimisation, which can cause fiscal stress and thus affect the efficiency of higher education. Objectives: The main objective is to examine mutual interaction of higher education indicators, through formulating financial models that connect performance and financial indicators. Methods/Approach: A total of 4 higher education indicators were analysed and observed in the time period of 10 years in selected CEE countries. The statistical analysis was based on panel data models. Results: The main result of the paper is the analysis of coherency of selected higher education indicators in selected CEE countries in order to establish functional links between government expenditure and efficiency through formulating financial models. Conclusions: Formulated financial models can predict the behaviour of selected performance indicators, depending on financial indicators. Therefore, the obtained models can contribute to the efficient allocation of funds and comprehensive macro-level decision making assessments in higher education policy reforms
Comparison of chemical and biological wireworm control options in Serbian sunflower fields and a proposition for a refined wireworm damage assessment
Recent European Union regulations aim at reducing the use of chemical pesticides in
agriculture. In sunflower production in Serbia, the use of synthetic insecticides for soil and seed
treatments has become a prevailing practice for wireworm (Coleoptera: Elateridae) control. However,
a number of compounds efficiently used as seed treatments have been phased out. This work aimed
at assessing the potential of an environmentally friendly “Attract and Kill” strategy (A&K) for
controlling wireworms in sunflower in comparison to conventional insecticides. The experiments
were carried out in 2018, 2019 and 2021 involving (a) soil treatments with ATTRACAP® and a Force
1.5 G; (b) seed treatments with Sonido, Force 20 CS, Lumiposa and Buteo Start 480 FS; (c) controls
(i.e., untreated seeds). The efficacy of the treatments was assessed based on the plant density and
emerging plant damage (%). A damage rating scale (levels 0–5) was created, aiming for a more reliable
and concrete interpretation of the results. Data were processed using binomial and multinomial
regressions, followed by modelling of the damage and calculating the odds of damage occurrence,
depending on the applied insecticide. In all experimental years and at all localities, the Force 20 CS
and/or Force 1.5 G treatments resulted in the highest plant density and the lowest percentage of plant
damage. ATTRACAP® showed good effectiveness, since plant density and percentage of damaged
plants were at the same level of significance as the commonly used conventional insecticides in
sunflower production (Sonido for seed treatment and Force 1.5 G for soil treatment). Thus, the
A&K strategy was efficient in controlling wireworms at conditions of low abundance, based on
three-year experimental results. Although the damage rating scale enabled a clear differentiation
of plant damage caused by wireworms responsible for reduced plant density, more reliable models
were obtained by binomial regressions, classifying plants as damaged or undamaged

1.1. The Special Colombeau Algebra
Abstract. Positivity and positive definiteness in algebra of generalized functions are studied. Basic definitions and notions of Colombeau algebra of generalized functions are given and some special classes of positive definite generalized functions on those algebras are introduced. Their relation to distributions is also investigated. AMS Mathematics Subject Classification (2000): Key words and phrases: Colombeau generalized functions, positive definite
The application of multimedia and its effects on teaching physics in secondary school
The paper presents the results of the pedagogical research conducted to
examine the effects of multimedia application on teaching physics compared to
the traditional method of teaching. The research was carried out on the
sample of 140 students of the first grade of technical school. The influence
of multimedia application in teaching physics on the quantum, quality and
retention of students’ knowledge was examined by the experimental method.
Knowledge tests were used as research instrument. Tests questions were
divided based on Bloom’s taxonomy into three basic categories: remembering,
understanding and applying. It was determined that multimedia application in
teaching physics had resulted in a significant increase of the quantum and
quality of students’ knowledge in all categories, as well as the retention of
knowledge quality in the category of applying compared to the traditional
method of teaching. Research results have shown the validity of multimedia
application in teaching practice with the aim of enhancing understanding of
fundamental physical concepts and laws, and therefore increasing the
efficiency of teaching physics
Cigarette Smoking among Medical Students from the Western Balkan
University student’s smoking is a significant public health problem. It is estimated that, globally, every fifth medical student is a smoker. So far, no research dealing with cigarette smoking among medical students has been conducted in the countries of the Western Balkans. The aim of this study was to examine the prevalence and risk factors of cigarette smoking among Western Balkans medical students. A cross-sectional study was conducted among 2452 students from 14 medical faculties in the Western Balkans (Republic of Slovenia, Republic of Croatia, Bosnia and Herzegovina, Republic of North Macedonia and Republic of Serbia). The data were gathered through an online survey. There were significantly more non-smokers than smokers among medical students. Only gender and parents smoking status were statistically significantly associated with students smoking status. The smokers were more often male students, who lived in urban areas prior their studies, and whose parents were both smokers. With the aim of monitoring and enhancing student population health, it is necessary for public health activists and health officials to continually survey the students’ smoking status in order to recognize the smoking influencing factors, and form and take on appropriate activities to improve the prevention of cigarette smoking among students, as well as motivate those who smoke to give up smoking, which would contribute to improving the health of the student population
Substituent effects on chromatographic retention data of 5-arylidene-2,4-thiazolidinediones in qsar methodology
Quantitative structure-retention relationship (QSRR) study of retention data of thirteen 5-arylidene-2,4-thiazolidinediones obtained by reversed phase HPTLC. The effect of substituents attached to aryliden ring on the properties of TZD molecule, whose retention is closely correlated to the inhibitory activity, was investigated. PCA was used to show similarities/dissimilarities among the compounds. Stepwise regression models were calculated for each mobile phase modifier used. The obtained models were characterized by good fit and predictive abilities. The descriptors included in the models are connected with both lipophilic and donor/acceptor interactions
