Ethnic Stereotypes in the Discourse of Former-Yugoslav TV and Cinema

This paper is an attempt to analyze particular scenes from the TV series “Složna braća” and “Crni Gruja” and the film “Balcancan” for the purpose of surveying the featured stereotypical representations of former-Yugoslav ethnicities, identifying their roles within the said examples of film and TV discourse, and proving that familiarity with the discursive practices of these particular cultures (discourse communities) is essential for interpreting these artistic discourses (texts) in the manner intended by their authors. Ethnic stereotypes are, therefore, discussed as socio-cultural constructs or myths generated by the discursive practices of a particular culture, as, it is discourses that “bring cultural objects into being by naming them, defining them and delimiting their field of operation” (Stam, Burgoyne and Flitterman-Lewis 2005: 216). They are also viewed as part of a larger structure – a discursive universe comprised of interrelated mythical texts (Johansen and Larsen 2002: 55–56) shaped by former-Yugoslav discourse communities. For this reason, the mentioned texts will be analyzed as sharing the said discursive universe

Knowledge in shadow – misconceptions related to light phenomena that are retained in spite of education

The paper Knowledge in shadow - misconceptions related to light phenomena that are retained in spite of education by Gordana Miščević, Sanja Blagdanić and Marija Bošnjak Stepanović emphasizes the need to point out the importance of initiating science education at an early age. In both children and adults, knowledge related to natural phenomena is created through interaction with the environment and through social interaction (with adults and peers), as well as through formal and informal learning situations. The aim of this research is to identify the frequency of various misconceptions related to light phenomena in fourth-grade students and primary school class teachers. Findings of this research reveal that the majority of students show a misconception related to the apparent change of the Sun’s position during daylight. Teachers mostly show no dilemma regarding shadow shape, and the same holds true for approximately two thirds of students. Additional findings are presented and discussed in the paper. Teachers should have an insight into the most frequent and typical misconceptions of students in order to identify them and react to them adequately. One of the main roles of the educational system is to identify these misconceptions and help students overcome themCollection name: LIBRARY "PEDAGOGICAL THEORY AND PRACTICE" 52This research is part of the project “Concepts and strategies for ensuring the quality of basic education“ — Faculty of Teacher Education in Belgrade (Contract No. 451-03-9/2021-14

The Effect of Fish Oil-Based Foods on Lipid and Oxidative Status Parameters in Police Dogs

The synthesis, degradation, and reconstruction of the cell membrane as a metabolic pathway of phospholipids is a constant and dynamic process. Fatty acids as bioactive lipid components of plasma and erythrocyte phospholipids as structural lipids have biological roles in the integrity of cell membranes. Fatty acids, depending on the chain length, the degree of saturation, and the synthesis pathways, can alleviate inflammation and oxidative stress caused by excessive exercise. Considering that changing food intake or diet can influence fatty acid phospholipid metabolism, our study aimed to determine the potential benefits of fish-based diets in working (police) dogs undergoing intensive training concerning bioactive lipids such as fatty acids, phospholipids of plasma, and erythrocytes. Fatty acid esters’ composition of plasma and erythrocyte phospholipids as a bioactive lipids, in addition to markers of oxidative stress and metabolic parameters, were analysed by GC chromatography. The food was well tolerated by all dogs, and the compliance to the diet was high throughout the study. After the treatment with fish-based food, blood glucose, total, and LDL cholesterol levels were significantly reduced, indicating positive biochemical profiles of dogs. Correlations of fatty acid phospholipid compositions between plasma and erythrocytes have shown that both plasma and erythrocytes could represent markers of omega-3 eicosapentaenoic and docosahexaenoic acid intake levels in dogs. Morover, fish-based food supplementation caused a significant reduction in lipid peroxidation markers. The enrichment of dogs’ diets with marine fish could improve oxidative status and improve roles and status of bioactive lipids, such as membrane phospholipids and fatty acids, as its components in plasma and erythrocytes in police dogs exposed to intensive exercise

AVAILABLE TREATMENT APPROACHES OF ACUTE INFLUENZA H1N1 INFECTION AND ITS CLINICAL COMPLICATIONS

Human H1N1 pandemic developed from the originally localized Mexican source early in the spring 2009. It seems that the current wave of infections slowly moves towards the southern hemisphere; however, the WHO reports on certain foci in Southeast Asia, Western Africa and tropic islands of the Middle America do not exclude another reccurrence in the northern hemisphere. This drew the attention of epidemiologists due to the fact that the virus owns a very unique capsid which expresses proteins coded by genes originating from the human, swine and avian influenza virus and was not covered by the available seasonal vaccines. Although most of the cases exibit classical clinical presentation of influenza infection, there are special features like significant gastrointestinal symptomatology and vulnerability of the young population. With respectively small but significant portion of patients there have been noticed fulminant course of infection with poor prognosis including sudden development of respiratory failure and consciousness disturbances which require intensive care unit admission. Cytokine storm should be mentioned as one of the key pathogenic events contributing to the overall mortality in substantial portion of patients. If active immunization is assumed to be preventive measure of proven efficacy, clinicians are still in doubt how to treat a complicated course of infection. We should be aware that the first choice essential drugs, for which viral sensitivity has been certainly proved, are neuraminidasis inhibitors. Here we have to distinct between more available oseltamivir and less available zanamivir and peramivir which until now have shown absolute effectiveness in inhibiting viral strains replication in vivo. Success of direct antiviral protocols has also been noticed with inhaled synthetic nucleoside ribavirine applied locally. Bacterial pneumonia superimposed by the overall patient status should be treated in accordance with the available evidence-based guidelines. We should be aware that septic lung infection caused by multiresistant organisms irrespective of intensive treatment remains the main cause of lethal outcomes in serious clinical presentations of H1N1 infection

Metformin-induced diarrhea as delayed adverse reaction after many years of use: Case report

Background: Metformin is an oral antidiabetic drug from bigvanides group. It does not cause hypoglycemia, and therefore has found its place as a first-line therapy in type 2 diabetes. It is used both as mono-therapy and as adjunctive therapy with other anti-diabetics and insulin. Some of the most common adverse reactions of metformin are: gastrointestinal upset, diarrhea, nausea, flatulence and vomiting. Adverse reactions usually occur at the beginning of the therapy. Aim: To show the potential of metformin to cause delayed adverse effects after years of use. Case report: A sixty-four-year-old woman with type 2 diabetes was treated with metformin for ten years. Several months ago she started to have diarrhea with fluctuating character and intensity. She lost 20 pounds in weight without a special diet. Gastroenterologist and surgeon were consulted, but the cause of diarrhea was not established. A clinical pharmacologist was consulted next to evaluate possible relationship between diarrhea and medication. According to the relevant literature, metformin had the highest prevalence of diarrhea among the medication that was taken by the patient. Therefore, the strategy of discontinuation and then re-challenge by the drug was used. Two days after the metformin was discontinued the diarrhea stopped, and five days later, after the patient was re-challenged by the drug, diarrhea reappeared, with similar characteristics as before. Conclusion: Metformin-induced diarrhea usually occurs at the beginning of the treatment. However, it could have delayed appearance, even after many years of continuous use of metformin

Primary School Students’ Misconceptions about Physical Properties of Water

Misconceptions are widely present among the students of all ages. The aim of this investigation was to determine the presence of misconceptions in understanding physical properties of water and to identify the most common ones. Quantitative analysis of data from the diagnostic conceptual test was performed on a sample of 243 first and third grade students from three elementary schools in Sombor, Serbia. It was shown that the impact of gender and school affiliation were not proven to be statistically significant factors in test achievements, while the children’s age significantly affects test results, as expected. Synthetic and scientifically correct answers were more frequent among the third grade students, while spontaneous answers were more common among the first graders. Nevertheless, a significant proportion of spontaneous answers implies that misconceptions about physical properties of water are almost identical and deep-rooted among students of both ages. Identifying children’s misconceptions provides a basis for development of accurate conceptual understanding

Pupils' Preconceptions about the Natural Phenomena at the Beginning of Primary Education – A Burden and/or an Opportunity

Learning about the world that surrounds a child begins well before the start of primary education. Experiential concepts, which children form in direct interaction with the environment, represent an experiential basis on which the formation of scientific concepts in the teaching process relies. Experiential notions based on ungrounded generalisations and misconceptions are also known as preconceptions, alternative ideas, and naive beliefs. The aim of this paper was to examine pupils' preconceptions about physical phenomena in the fields Physical Properties of Materials, Movement and Light at the beginning of primary education. The survey was conducted on a sample of 324 students, by using a criteria-based test of knowledge. The results of the research indicate that seven-year-olds from Serbia have some typical preconceptions and doubts that were confirmed by the previous research conducted in other countries (United Kingdom, USA). The respondents had the fewest misconceptions about the movement of bodies, while they mostly had wrong beliefs about the physical properties of materials. Given that the identification of the preconceptions that pupils have at the beginning of primary school can be useful for the creators of educational policies, textbook authors and teachers when deciding which physical phenomena should be given additional attention because they are not well understood by students, or what phenomena are pupils already familiar with, a more in-depth research of this content in teaching is necessary

Impaired endothelial function in lone atrial fibrillation

Background/Aim. Impaired endothelial function has been previously documented in patients with atrial fibrillation (AF) and underlying comorbidities or older patients with idiopathic AF. The aim of this study was to evaluate systemic endothelial function in younger AF patients (less than 7 days) lone AF. The second group comprised of 28 healthy controls in sinus rhythm (the mean age 43 ± 13, 53% male), matched by age, gender and atherosclerotic risk factors. All the participants underwent physical examination, laboratory analysis [including determination of C-reactive protein (CRP)], standard echocardiography and exercise-stress testing. Brachial artery FMD and endothelium independent dilation (NMD) were assessed with a high-resolution ultrasound probe and arterial diameters taken from 5 consecutive cardiac cycles were averaged for each measurement to accommodate to beat-to-beat flow variations in AF. Results. There were no differences between the 2 groups regarding age, gender and most clinical, laboratory and echocardiographic characteristics (all p > 0.05), apart from the increased heart rate (p = 0.018), body mass index (p = 0.027), CRP levels (p = 0.007) and left atrial anteroposterior dimension (p 0.05). In the multivariate analysis, the independent FMD determinants in our study population were the presence of AF, smoking and total cholesterol levels (all p < 0.001). In patients with AF, the strongest independent FMD determinant was arrhythmia duration (p < 0.001), followed by smoking (p = 0.013) and total cholesterol levels (p = 0.045). Conclusions. Our findings confirm that sustained AF is associated with systemic endothelial dysfunction even in relatively young patients with no cardiovascular disorders or risk factors. AF is an independent contributor to lower FMD and a prolonged arrhythmia duration may confer the risk for more profound endothelial damage

The use of the research method in teaching the physical properties of water in introductory science instruction

The research method provides an opportunity for students to be gradually involved in the process of active learning, leading to the development and comprehension of educational content through the asking of questions, information analysis and critical thinking. The paper presents the results of research on the effectiveness of using an instruction model with the applied research method in teaching the physical properties of water in introductory science instruction. The sample comprised 109 primary school students (55 in the experimental group and 54 in the control group) in the town of Sombor and the village of Gajdobra, Serbia. Initial and final knowledge tests were used to measure the quality of students' knowledge of the physical properties of water, and the descriptive, causal and comparative methods were used to analyze the findings. The analysis suggests that the use of the research method results in higher quality knowledge compared to traditional approaches to introductory science teaching
