Published: December 2022

The plain grasslandsin Western Romania are real germplasm reservoirs for Birdsfoot trefoil. The Birdsfoot trefoil occupies all the gaps in the natural meadows, where other legumes fail because it has a great capacity to adapt to harsh conditions. Wild Birdsfoot trefoil populations, from the grassland flora, are reservoirs of genes with tolerance to environmental factors, resistance to diseases and pests. In this context, the paper aims to evaluate the genetic potential of some populations of trefoil, obtained from seeds harvested from the spontaneous flora of the plain grasslandsof Western Romania, in terms of important quantitative features, which will have a theoretical basis for obtaining new varieties. Birdsfoot trefoil populations analyzed in the paper come from seed harvested in natural grasslandsin the plains of the Banatregion,in WesternRomania. The seeds were sown in vegetation pots and in the spring of 2019 the plants were transplanted in the field. In this study,all data on the main characteristics analyzed were obtained in the second year of culture (2020).Birdsfoot trefoil analyzed populations fluctuate the studied characters and can be successfully used in breeding programs for creating new varieties. The Lv8population proved promising for its characters: the number of generative shoots per plant, the number of umbels per plant, the number of pods per plant, the number of seeds per plant, and the weight of seeds per plant.In the future, plant breeding will require an expansion of the genetic base to meet the challenges posed by climate change and the need to ensure food security,which requires the use of more local people in raising the productive level of Birdsfoot trefoil culture.

Breeders are permanently looking for effective methods for developing cultivars with improved yield. For that goal, they should include different genotypes in many cross combination to obtain the recombination of desirable genes. The biological material was composed of 11 winter wheat varieties with different origin: Alex, Boema, Ciprian, Izvor, Glosa (Romania); Laurentio, Renan (France); Josef, Galio (Austria); Akteor, Exotic Germany). The wheat varieties were evaluated regarding the following traits: plant height; spike length; spikelet number/spike; spike weight; grain number/spike and grain weight/spike. This study evaluated the diversity of 11 winter wheat varieties with different origins for some plant yield traits, and the possibilities of using these varieties in breeding programs. Higher plant stature of Josef, Galio and Laurentio varieties was associated with the highest values of spike weight, number and weight of grains/spike, and values above the mean for spike length and spikelets number/spike, respectively. The results of this research show that some varieties achieved high values for different traits of plant yield. Therefore, these varieties are successively used  for further breeding programs based on diallel-crossing methods, to develop new wheat varieties. For these varieties, the spike weight has the highest and significant contribution (64,83%) to the achievement of plant yield, followed by the plant height, which contributes with 10,26 % to the variability of this trait. The spike length and grain’s number/spike had the lowest influence on plant yield. According to the high diversity between some varieties like the following Glosa-Akteor; Izvor-Josef; Izvor-Akteor; Josef-Exotic, these pairs are suitable for crossing to obtain hybrids with useful gene combinations for different yield components. Considering the highest variance for plant height and spike length, we appreciate that it is possible to identify valuable gene combinations for these traits in segregating generations.

New technologies in agriculture have allowed farmers to reintroduce low-fertility land into the production circuit by using organic fertilizers based on live bacterial crops, crops that are beneficial to the soil and agricultural plants. This paper aims to present both an innovative product in Romanian agriculture - a 100% Romanian fertilizer. Within the Research-Development Station for Agriculture Suceava, an experiment was performed on the wheat agricultural crop, with a biological fertilizer (Rom-Agrobioferti NP) in parallel with a chemical fertilizer (Complex 20: 20: 0). The results obtained within the resort for the biologically fertilized lot showed increases of the established parameters, much higher increases than the chemically fertilized lot. The most important aspect of the established parameters was the parameter of agricultural production. This parameter showed an increase of approx. 43.41% (production of the biologically fertilized lot vs. production of the chemically fertilized lot).

The present paper presents the variability of some yields and non-yields components of a group of ten varieties of spring wheat. Flag leaf area, chlorophyll concentration, spike length, number of grains/spike, weight of grains/spike and estimated grain yield were analyzed as yield components or morpho-physiological traits with a high impact on final grain yield. Flag leaf area surface has a direct an important contribution to determine increased number and weight of grains per spike. Chlorophyll concentration determined from flag leaf at early milky stage is significant correlated with weight of grains per spike (0.64*) which means that maintaining of a high level of chlorophyll pigments in leaf contributes decisively to high grain yield. Grain yield performance of genotypes can be appreciated based on the preliminary information given by chlorophyll concentration measured in advanced generative stage. Obtaining information previous final grain yield creates the possibility of pursuing more closely of a valuable breeding material while eliminating non-conforming genotypes.

Published: December 2022

The study analyzed in dynamics a rapeseed culture based on remote sensing. Satellite images from the Landsat 8 system were used. The images were taken at 8 different time points, t1 (March), t2, t3 (April), t4, t5 (May), t6, t7 (June), t7 (July). Based on spectral information, NDVI and MSAVI indices were calculated. The variation of the values of NDVI and MSAVI indices in relation to time was described by polynomial models of 2nd degree, in conditions of statistical accuracy (R2=0.798, p=0.0182, F=9.9134 for NDVI, respectively R2=0.851, p=0.00856, F=14.286 for MSAVI). In the case of both indices, a deviation of the values of the moment t4 (flowering period) was found in relation to the theoretical model obtained. The regression analysis facilitated the obtaining of a production prediction equation (YP) based on the values of the NDVI and MSAVI indices, in statistical accuracy conditions, R2=0.994, p=0.0105, F=94.1279. The prediction error (PE) was calculated compared to the actual production obtained, and the moments t1, t2 and t3 facilitated the estimation of the production under the most accurate conditions (PE values were minimal). 3D and isoquants models were obtained and they have described the variation in estimated YP output in relation to NDVI and MSAVI. A high level of similarity regarding PE was recorded in the case of t1, t2 (SDI=17.098), respectively t2 and t4 (SDI=18.098). According to the PCA, PC1 explained 67.745% of the variance, and PC2 explained 32.037% of the variance.

At A.R.D.S. Secuieni (Agricultural Reseach and Development Station Secuieni) was followed the evolution of the structure of the vegetal carpet to some mixtures of perennial grasses and legumes, with mixed use, taking into account the mode and duration of use, but also the capacity of competition between the studied species. In the technology of cultivation of temporary meadows, the composition of the mixtures is the most important work because it largely depends on the yield and evolution of the composition of the plant carpet. During 2018-2020, research was carried out on three mixtures of perennial grasses and legumes, under the influence of doses of nitrogen fertilizers on phosphorus agrofund. The experience was placed on a phaeozium-type soil, according to the method of subdivided plots into a bifactorial experience, in four repetitions. In the experience, the A factor was represented by fertilization, with four graduations a1 - N0P0, a2 - N40P40, a3 - N80P40, a4 - N80 + 40P40, and B factor was represented by the mixture between grasses and perennial legumes, with three graduations b1 - 85% grasses + 15% legumes (control), b2 – 90% graminee + 10% legumes, b3 – 90% graminee + 10% legumes. In the structure of the vegetal carpet, the percentage of participation of legumes increased slightly, and the grasses had a decreasing tendency compared to the percentage of participation at the sowing norm. Various species from the group were present, and the participation percentage was between 0 - 3.1% at scythe I, with a tendency to increase from one scythe to another.

This study evaluates the influence of agronomic biofortification with zinc on the productivity and quality of winter wheat. The large number of people, globally, affected by the nutritional deficiency of minerals, requires urgent measures to remedy this shortcoming. Agronomic biofortification of zinc cereals is much faster than biofortification through breeding programs. The experiment took place at ARDS Lovrin and was placed in the field according to the randomized block method, in three repetitions. The three experimental factors - factor A - seed treatment, with the following graduations: a1 - without seed fertilization, a2 - with seed fertilization, factor B - variety: b1 - Ciprian variety, b2 - Glosa variety, b3 - Dacian variety and factor C - zinc treatment - c1 - unfertilized control, c2 - soil fertilization, c3 - foliar fertilization at the end of the tillering period, c4 - foliar fertilization in the heading phase, c5 - foliar fertilization in the milk phase, were study both unilaterally and in different combinations. It is noted, in the climatic conditions of the experimental period, as the fertilization variant to increase the zinc content in the grain, the variant with soil fertilization with zinc sulfate, when combined with seed treatment. In this combination, the highest values of zinc in the green plant, in the grain, the best production and quality results, statistical assurance for the probability of transgression of 5% and 1% respectively, are recorded. Regarding the formation of productivity elements - spike length, spike weight, number of spikelets in spike, number of grains in spike, weight of grains in spike - obvious correlations are established between them and the fertilization system approached. Thus, the number of spikelets in main spike correlates very significantly with the length of the spike (r = 0.73***), the number of grains in the spike correlates significantly with the length of the spike (r = 0.68**) and with the number of spikelets/ spike (r = 0.65**), the weight of the spike correlates very significantly with the number of grains / spike (r = 0.73***) and significantly different with the weight of the spike (r = 0.59**) and with the length of the spike (r = 0.57**).

Soybean is one of the most important crops in the world due to its high nutritional value and also because its importance in crop rotation. Soybeans have relatively high requirements for soil nutrients, but also for its structure. Adequate nutrient support can ensure both high and stable yields and a high fat and protein content, soybeans being considered an important source of macronutrients. In order to estimate the genetic parameters of some yield components and quality traits in soybean crop, a two years polifactorial experiment was carried out at Research and Development Station for Agriculture Turda, Romania (RDSA Turda). The experiment had an area of 57 x 35 m and was based on a subdivided parcel design with three replications, using plots of 5 m2. It included 13 soybean cultivars from three maturity groups fertilized with 3 different doses (without fertilization, 150 kg/ha, 200 kg/ha, 250 kg/ha complex fertilizer) and two mineral fertilizers (NPK 16:16:16 and NPK 27:13.5:0). Seven varieties (Perla, Carla TD, Felix, Onix, Caro TD, Ada TD, Raluca TD) and six perspective lines (T-295, T-161, T-165, T-6117, T-166, T-6126) developed at RDSA Turda were used for the experiment. Yield, insertion of the basal pods, number of pods/plant, number of grain/plant, grain weight/ plant and thousand kernel weight (TKW), were studied. Regarding the quality parameters, fat and protein content were analysed. The results obtained reveald that yield, yield elements, protein and fat content were very high influenced by the genotype. Small influence of the experimental factor dose of fertilization in yield was observed. Regarding the genetic parameters, for seed size (TKW) was recorded high values for heritability in broad sense, for genetic advance and also for genetic advance in percent, sugesting that soybean grain yield cand be improved by the direct selection of genotypes with high values of TKW.

Potato (Solanum tuberosum L.) is considered "the second bread of the country" due to the use of tubers in a wide range of foods and in the production of potato flakes, chips, and flour. It is also an important raw material for the alcohol, starch, glucose, dextrin etc. industry. The biological material used in the research consisted in 14 Romanian potato varieties developed in laboratories specialized in this species, namely: the National Institute of Research and Development for Potato and Sugar Beet from Braşov (cv. 'Asinaria', 'Cezarina', 'Sevastia', 'Brașovia', 'Castrum', 'Marvis', 'Sarmis' and 'Ervant'), and the Potato Research and Development Station from Târgu-Secuiesc (cv. 'Albioana', 'Armonia', 'Nemere', 'Productiv', 'Redsec' and 'Gared'). Experimental potato varieties were included in a monofactorial comparative culture, according to the four-replication randomized block method. The area of the experimental parcel was determined by the number of plants (200 plants / variant) and planting scheme. Thus, the number of plants per area unit was depended on the maturity group, namely: midlle early varieties (47,600 plants / ha; 0.70 m between rows x 0.30 m between plants / row), midlle late varieties (40,800 plants / ha; 0.70 m between rows x 0.35 m between plants / row) and late varieties (35,700 plants / ha; 0.70 m between rows x 0.40 m between plants / row). From the comparative analysis of morphological characters (number of tubers / hills) and yield (average tuber weight, yield per hill and area unit) one can highlight the following genotypes depending on maturity group, namely: midlle early Asinaria variety, and midlle late 'Albioana', 'Braşovia', 'Productiv', and 'Sarmis' potato varieties. Taking into account the costs of potato culture and the production price for consumption potatoes in pedo-climatic conditions in western Romania, efficient productions of over 45 t/ha (yield/ha of tubers φ > 55 mm) are required.

In the past, castor was grown in our country on large areas, but today there are few who have heard of this plant and far fewer who rely on the establishment of a castor crop in the field. The experience was placed at Society Agricola Moldoveni from Neamt County, and the preliminary results obtained are the object of study of the doctoral thesis. The average productions obtained in 2021 were directly influenced by the experienced technological factors. The highest seed production was made at the earliest variety, Teleorman sown in the second epoch at the distance of 70 cm between rows (1669 kg / ha). The correlation between the three studied factors (variety, epoch of sowing and distance between rows) and the yield obtained was directly and very close.

The study evaluated the fertility and spatial variability of some agricultural lands, in the area of Cenei locality, Timis county, Romania. The soil samples, representative for the studied agricultural lands, were taken from nine different locations. The soil reaction (pH, H2O), total nitrogen content (Nt), mobile potassium content (K, ppm) were considered and studied, and the degree of saturation in basic cations (V,%) was calculated. The soil reaction showed values between pH = 6.29 - 7.97 ±0.20, the degree of saturation in basic cations (V,%) had values between V = 74.80 - 100.00 ±3.13%, total nitrogen showed values between Nt = 0.11 - 0.35 ±0.03%, and the potassium content showed values between K = 275 - 390 ±15.49 ppm. High variability was recorded in the Nt index values (CVNt = 38.3598) and low variability in the soil reaction (CVpH = 8.3248). For the other soil indices studied, intermediate values were recorded, respectively CVV = 9.9760 for the degree of saturation in basic cations (V%), and CVK = 13.7177 in the case of mobile potassium content (Kmobil). The variation of the mobile K content in relation to the soil reaction (pH) was described by a polynomial equation of degree 2, equation (1), in statistical safety conditions, at the level of R2 = 0.779, p = 0.0121. Under PCA, PC1 explained 69.593% of variance, and PC2 explained 25.919% of variance. Cluster analysis facilitated the grouping of soil samples into two separate clusters, with three sub-clusters, under Coph. coeff. = 0.859.

Published: December 2022

Bromus tectorum causes special problems because of its ability to reproduce through seeds and also because it’s relative tolerance to numerous herbicides. Extending new tillage systems, conservative systems specific to conservative sustainable agriculture, is a difficult task to accomplish under the circumstances of strong monocotyledonous weed infested Bromus tectorum is one of the most dangerous monocotyledonous weeds when applying unconventional system. A research was conducted in the pedoclimate condition of Agricultural Research and Development Station Turda, investigating the control of Bromus tectorum by conservative tillage. The goal was to determine the relationship between agricultural system and weeding degree on winter wheat. The use of minimum tillage and no tillage systems, caused at the end of a three year crop rotation, the increase of the Bromus tectorum pervasion in two systems, MD and NT. The occurrence of B. tectorum it is caused mainly due to the fact that the seeds are located in the first cm of the soil. Total weed density was significantly lower under the conventional tillage system (CS) and minim-chisel (MC) than under the minimum tillage-disk (MD) and no till (NT) system. The main benefit of the conventional tillage (CS) is a highly important decline of weeds.

Considering the continued and unpredictable variation of climatic condition, the yield stability has become an important topic in wheat breeding. This study evaluated the grain yield of 11 winter wheat varieties with different genetic and ecologic origin during three years, to compare  the effects of genotype, year and genotype × year interactions and to determine their stability and reliability for cultivar recommendations. The climatic conditions during the three years had the highest contribution (80.03%) to the yield variability of wheat, while the varieties had a lower influence (11.41%), and the variety x year interaction contributed only with 8.56% to the total variation. In 2020, the climatic conditions were significantly more favorable than in 2018–2019, allowing obtaining yield increases of 33.82-44.20%. Also, in 2018 there was a higher favorability of the growing conditions compared to that of 2019, associated with significant yield increases of 7.75%. The highest yield stability was observed in Boema and Galio varieties, on the background of a non-crossover genotype x environment (GE) interaction. The stability of these varieties has been associated with different yield levels, above the experience mean in Galio and below the experience mean in Boema, respectively. In Akteur and Josef varieties, the yield was strongly influenced by the GE interaction, being associated with lower levels than the experience mean. On the background of high occurrence probabilities (0.75–0.95) of unfavorable environmental conditions for wheat crop, Galio and Laurenzio varieties would have the highest yield reliability, associated with values of 5173–6328 kg/ha (Galio) and 5101–5979 kg/ha (Laurenzio). As such, given the results of all stability parameters, it turns out that the Romanian varieties showed a good adaptation to the local ecological conditions compared to most of the foreign varieties.

Grasslands are spread all over the globe, their distribution being possible by various modern methods. The spatial representation of the grasslands, in correlation with other categories of land use, provides us with an overview of the activities of the geographical area and also represents a first stage in the field research. In this context, the purpose of the research is to analyze the territorial distribution of grasslands through geographic information systems (GIS), based on land use maps and to identify natural and anthropic factors with direct and/or indirect impact in their spatial modeling. The study area is characterized by variable conditions of landform, being partially located in the following physical-geographical units, Vinga plain, Gătaiei plain, Timiș plain, Lipova Hills, The Sacoș-Zăgujeni Hills and Anina Mountains. As representative of the analyzed area, we chose five ATUs, framed in a working transect. In the sub-areas of the analyzed work transect there are variations in the way of organizing the land, respectively in the territorial distribution of the grasslands. Thus, the largest areas of grassland are present in ATU Recaş (6253,83 ha) which has a hilly appearance (with altitudes between 90 – 287 m). Large areas of grasslands are also found in ATU Fârliug (3.163,23 ha) and ATU Pișchia (2255,25 ha) located in different landform conditions. The smallest areas of grasslands are found in ATU Vermeș, respectively 861,63 ha. From the point of view of the territorial distribution, the areas of grasslands shall be grafted on all forms of landform and under all environmental conditions in the territory under consideration. The share of grassland depends on natural factors (soil, climate, landform) but also on the other production activities, specific to each area, which is also found in the distribution of the other land use categories, for each ATU.

O uso de recursos tecnológicos para o ensino de leitura e de escrita baseados em princípios da Análise do Comportamento tem se mostrado eficiente e eficaz com diferentes públicos. O presente estudo avaliou a aquisição de escrita de dois alunos com deficiência intelectual empregando o Módulo 1 do currículo informatizado Aprendendo a Ler e a Escrever em Pequenos Passos (ALEPP). Esse Módulo ensina palavras regulares, do tipo consoante-vogal (exemplo, “vaca"), a partir de tarefas que envolvem a relação entre palavra ditada e palavra impressa, e a cópia e o ditado por composição de letras. Os participantes, de 19 e 25 anos, frequentavam a Educação de Jovens e Adultos e tinham repertório inicial de leitura de palavras regulares, acima de 70% de acertos, mas baixo desempenho em escrita por ditado, variando entre 6,7% e 60% de acertos. Após o ensino, observou-se aumento no repertório de escrita dos dois participantes, com acertos de 93,3% e 100%. Na avaliação de manutenção realizada com André, após um mês, e com Ana, após cinco meses, os participantes mantiveram os altos desempenhos (maior que 80% de acertos). Em uma análise de erros da escrita sob ditado, constatou-se inicialmente maior ocorrência de substituição de letras e escrita silábica. Após o ensino, os erros se pautaram na substituição e na omissão de letra. O programa de ensino se mostrou eficaz para aquisição de escrita de palavras simples para jovens com deficiência intelectual. Estudos futuros devem ampliar a amostra e verificar a generalização do repertório para a sala de aula.

Los trabajos adelantados por la psicología, y en particular por la psicología educativa, han establecido relaciones entre conductas de prejuicio en los niños y procesos de exclusión en el aula. En otras palabras, se ha pensado que las conductas infantiles que se sustentan en prejuicios relacionados con la raza, la orientación sexual o las identidades de género, así como con formas distintas de la discapacidad, o los rasgos de personalidad que se hallan por fuera de parámetros de la normalidad, a menudo se asocian con procesos de exclusión. Son dos los mecanismos de aprendizaje de los organismos: los de tipo implícito (actividades adaptativas que no son el resultado de una voluntad de aprender, sino que son rutinarias entre los individuos), y los de tipo explícito (aprendizajes de mayor complejidad y exclusivamente humanos). Es objetivo del artículo mostrar cómo la educación puede contribuir a los otros a eliminar sus prejuicios (principio de toda forma de exclusión), porque todo prejuicio es adquirido por las vías del aprendizaje implícito. Para lograr este objetivo, tomamos como método la revisión y lectura temática de fuentes de dos tipos: 1) la literatura sobre el concepto de prejuicio desde el ámbito de la psicología social; 2) trabajos recientes sobre psicología del aprendizaje. Al final, proponemos que la eliminación del prejuicio se logra a través de procesos educativos que se orientan al logro de aprendizajes de tipo explícito.
Debates para uma (des)construção da política de educação especial no Brasil
Authors: Kassar Mônica de Carvalho Magalhães
Published: December 2022

Em 2008, a Política Nacional de Educação Especial na Perspectiva da Educação Inclusiva foi divulgada, fornecendo linhas orientadoras para a organização da educação especial na educação brasileira. Em novembro de 2018, uma “consulta pública” online foi veiculada pelo Ministério da Educação divulgando a revisão dessa política. A considerar o momento de avanços conservadores em torno dos direitos constitucionalmente constituídos no campo da Educação, este artigo tem o objetivo de evidenciar e analisar argumentos apresentados por representantes da sociedade civil e do governo, prós e contra a revisão, em um Seminário organizado pela Câmara do Deputados sobre esse tema, no início da consulta pública de 2018. O trabalho foi construído com a utilização de dois tipos de documentação: o registro do Seminário, elaborado pelo Departamento de Taquigrafia, Revisão e Redação – DETAQ, da Câmara dos Deputados; e notícias veiculadas sobre esse processo nas páginas WEB das entidades envolvidas no Seminário. Os argumentos escolhidos para a análise foram: a necessidade de debate democrático; os dados de pesquisa; a posição da Organização das Nações Unidas; a utilização do slogan “nada sobre nós sem nós”; e argumentos religiosos. As análises do Seminário e de seu contexto indicam a existência de disputas e uma tendência à desconsideração dos mecanismos de participação coletiva, à adoção de um viés conservador nas propostas políticas e à desconsideração da escola pública como instituição republicana.
The contribution of Dimitrije Matić to adult education in Serbia in the 19th century

Published: December 2022

The work was written with the goal of determining and describing the contribution of Dimitrije Matić to establishing and developing adult education in Serbia in the 19th century. We employed the historical method and within it an analysis of content, discourse and narrative of primary and secondary sources. The results of the research demonstrate the exceptional contribution of Matić to the development of institutional adult education through the establishment of a network of reading rooms in Serbia, the (re)opening of adult schools, the constitution of school boards, and the renewal of teacher education. We identified contributions in the sphere of instituting adult education legislature and the creation of institutional, staff, program and financial prerequisites for the operation of adult education institutions. We identified the bases for questioning the success of the functioning of certain andragogical institutions established by Matić, which doesn't undermine his importance in the pioneering endeavours of developing adult education.
The quality of adult training: Two perspectives
Authors: Milićević Aleksandra , Pejatović Aleksandra
Published: December 2022

The work examines the issue of adult training quality. Our analysis rests on two perspectives, i.e. evaluations of training quality, which frequently vastly differ from one another, as we are about to see. Both the trainees and independent estimators-andragogues reviewed the quality of the training. The research of training quality has been performed on the basis of double evaluations of certain aspects (properties, traits) and elements (constituent parts) of adult vocational training at an informal educational institution in Belgrade. Following the theoretical analysis of key terms, such as the quality of adult education and adult training, the work presents the methodological framework of the empirical segment of the research, with a more detailed analysis of the achieved results. The analysis prompted us to conclude that examining training quality from the perspective of two different participants results in two very different evaluations and thus perceptions of training quality. Such findings bring us back to certain fundamental questions regarding the quality of (adult) education and highlight the complexity of "measuring" quality and quality management, in that regard. Furthermore, within our final remarks, we presented a pathway to the present development of a quality system for training and organizational work with the status of JPOA (publicly recognized organizer of adult education activities) in Serbia and we additionally highlighted various orientations towards quality in adult education.
The Bologna process in Serbia as perceived by art faculties students and professors
Authors: Prnjat Dejana
Published: December 2022

The goal of the research is to analyse the aspects of the application of the Bologna process principles in higher arts education by examining art faculties students' and professors' views regarding the systematic change within the higher education reform in Serbia, stemming from the Bologna Declaration. Qualitative research was conducted by employing semi-structured interviews with sixteen students and teachers at public and private art faculties. The interview agenda comprised two thematic blocks: the positive and negative aspects of the application of Bologna principles as perceived by art faculty students and the positive and negative aspects of the application of Bologna principles as perceived by art faculty teachers. Data have been analysed by employing the principles of thematic analysis. The possibility of student and teacher mobility was underlined among the positive aspects or categories. The lack of appreciation for the specificity of art education which is not disposed to formalization, i.e. the credits and administration system, was emphasized among the negative aspects or categories.

Authors: Janaćković Tanja , Georgiev Maša , Janaćković Marko
Published: December 2022

The focus of the paper is liquidity analysis, which is an essential tool of the corporate financial management process. Converting assets, especially working capital, into cash is the primary way for a company to obtain the resources it needs to pay its current liabilities. The aim of the research is to look at the movement of current, quick and cash liquidity indicators, their comparative analysis, as well as differences in the level of liquidity for the period 2011-2020 on the example of certain oil companies in the Republic of Serbia. Ratio analysis based on their official financial statements was used to measure the liquidity of selected companies (NIS, OMV and LUKOIL), while the one-way ANOVA test was used to test hypotheses. The research results show that there is a statistically significant difference in the level of current liquidity between NIS and LUKOIL and OMV and LUKOIL, while there is no significant difference between NIS and OMV. There is a statistically significant difference in terms of quick ratios between NIS and LUKOIL, while there is no significant difference between NIS and OMV and OMV and LUKOIL. Observing the cash liquidity indicator, there is no significant difference between these indicators in the companies that are the subject of the research.

Published: December 2022

On February 1st 2016, the Republic of Serbia acquired the status of a full member of the European Union Convention on Common Transit Procedure, and joined the existing members: EU countries, EFTA countries, as well as individual members Turkey and the Republic of North Macedonia. In this way, Serbia put its particularly important geopolitical position in Europe, and its openness to support and acceptance of foreign direct investments, into the function of further dynamic improvement in the sphere of economy and overall economic development.
Why people commit infidelity: 'Nothing personal' or 'very personal:' Machiavellianism and subclinical sadism as predictors of infidelity
Authors: Mraović Dunja , Borišev Nikola , Gojković Vesna
Published: December 2022

Apart from the proximate incitement, infidelity implies an intention to inflict harm and suffering to a perpetrator's regular intimate partner for the sake of the perpetrator's own pleasure. The aim of this study was to determine whether Machiavellian deceit (infidelity as a conative style, i.e., 'nothing personal') or subclinical sadism (infidelity with the overt intention to hurt, i.e., 'very personal') is the dominant impetus of infidelity. Our data collected on 111 female and 48 male respondents indicated that Machiavellian antagonism and agency were the best predictors of adulterous behaviour, thus highlighting its 'nothing personal' dimension. No indices of subclinical sadism proved their incremental predictive power in the regression model, thus challenging the 'very personal' approach to the underpinnings of infidelity. In addition, there was no evidence of sex-related differences in proclivity to infidelity.
The effects of perceived social support on loneliness
Authors: Šolak Radojka , Dragičević Jelka
Published: December 2022

The principal objective of this research is to test the effects of perceived social support on loneliness with various age-dependent respondents during the COVID-19 pandemic. The sample is made up of 442 respondents (41% male), who are arranged into five age categories: up to 25, 26-35, 36-45, 46-55, over 55 years old. These subsamples are administered according to the UCLA Loneliness Scale (Russell et al., 1980) and The Multidimensional Scale of Perceived Social Support (Zimet et al., 1988), which measures perceived social support from three sources - family, friends, and significant other. The results of regression analysis show that in all five models the perceived support of a friend is a statistically significant negative predictor of loneliness, while the perceived support of family is a significant negative predictor of loneliness with respondents up to 25, from 36 to 45 and over 55. Support of significant other is a statistically significant negative predictor only in the sample of respondents from 46 to 55 years old. Results show that a significant predictor of loneliness for respondents of a specific age category is the sense of support from a person who is largely not fulfilling that role.
The level of English language competence among employees in foreign trading companies in Serbia
Authors: Živković Milan , Drašković Jana
Published: December 2022

Due to the globalization and high demand of international market, business correspondence is being performed mainly in English, making the English language lingua franca in international trade. This paper shows in what degree the English language is, as the language for specific purposes, important in the international trading companies; it studies the connection between the professional position of an employee in a company, the usage and understanding of the language. Together with examples from the research conducted, this paper provides some answers to the questions - what professional positions are most likely to change in terms of the English language usage, that is, on which professional positions is the language known best?
Antibiotic treatment of community-acquired pneumonia
Authors: Jovanović Saša
Published: December 2022

Major cause of infective diseases morbidity and mortality is community-acquired pneumonia (CAP). Incidence is constantly increasing, particularly among older population. Therefore, more and more attention is given to progress in diagnostics, prevention and treatment of the disease. Most of the patients with CAP are treated empirically, and selection of universal antibiotic treatment is difficult due to changeable epidemiology, partly because of the antimicrobial resistance, partly because of the geographic variations of most common pathogens. In the selection of antibiotic therapy security profile and efficiency of known antibiotics must be taken under consideration as well as principle of rational use due to the risk of resistance. Therapy guidelines are taking in consideration regional specificity like available diagnostic procedures and antimicrobial resistance and recommend appropriate therapy regimes.

In a Banach space we consider a class of linear non-autonomous neutral type differential equations with several delays. For the considered equations we derive explicit delay-dependent input-output stability conditions. Applications to neutral type integro-differential equations are also discussed.
Structural, production and development characteristics of sessile oak on Fruska Gora mountain
Authors: Matović Bratislav , Stojanović Marko , Stojnić Srđan , Kostić Saša , Stojanović Dejan
Published: December 2022

In the paper, the structural, production and development characteristics of a potentially overripe and devitalized sessile oak stand on Fruška Gora were investigated. Structural and production characteristics were investigated on the ICP Forests plot Level 2, where data from two surveys in 2015 and 2020 were used. Developmental characteristics were investigated using center cores of 22 dominant sessile oak trees sampled in 2014 and using electronic and manual dendrometers on six trees from 2015 Topola/Poplar 2022, 210, 29-40 www.ilfe.org 30 to 2022. The diameter distribution shows that the researched stand is two-storeyed and mixed, and based on the diameter distribution of the first floor, it was a pure even-aged stand of sessile oak in the past. Productivity in the period from 2015 to 2020 shows stagnation, but with a clear decrease in the share of sessile oak, especially in the total basal area and volume. By analyzing the age and development characteristics, individual trees show clear signs of devitalization during most of their life, and for the whole stand we can conclude that it is significantly too old and in clear devitalization, especially after 2019. The diameter growth in the growing season is characterized by small values and predominantly occurs in May and June. The general conclusion is that the researched stand is overaged, devitalized (the main species of the stand is the sessile oak), with the regression of the sessile oak in relation to other competing species and very slow growth dynamics even on an annual basis, which from the perspective of future management puts the forestry profession in a very unenviable role and requires an adaptive approach to managing such stands.
Population ageing in selected ex-Yugoslav states
Authors: Sekulić Milena
Published: December 2022

This article presents main indicators of population ageing in Republic of North Macedonia, Republic of Slovenia and Republic of Serbia. Main indicators used in this paper are proportion of old population and "older-old" population, old dependency ratio, ageing coefficient and median age. The aim is to observe and detect similarities and differences in the age structure of the region based on indicators of ageing. The results are shown that Serbia is a country with the oldest population: 13.8% old population, 3.6% "older-old" population, the old dependency ratio 25.45 people per 100 people of working age, and 42.5 median ages. The Republic of North Macedonia has a younger population compared to other countries.
