Published: July 2023

Introduction. In El Paso, Texas, a largely Hispanic population, a large surge of COVID-19 occurred in October 2020. Using public health surveillance data and a field survey we report on the epidemiology and control of this pandemic in 2020.

Population and methods. We used reported COVID-19 cases to the notifiable disease reporting system to: 1) calculate morbidity and mortality rate ratios by age, gender, race/ethnicity, and poverty; and 2) to assess temporal trends using joinpoint regression. A door-to-door cluster sampling serologic survey assessed prevalence of SARS-CoV-2 infection. We calculated the relative excess risk due to interaction (RERI) of older age and diabetes on mortality from COVID-19.

Results. By the end of 2020, the reported morbidity and mortality were 0.8% and 216.8 per 100,000 population, respectively. The overall prevalence of infection reached 18.5%. Compared to those under 20 years of age, the reported morbidity was nearly twice among 65+ years of age (RR=1.6 [95% CI=1.6, 1.7]), but the mortality in this group was disproportionately large (RR=1,026 [95% CI=329.0, 3,171.0]). Hispanics had twice the morbidity and mortality than non-Hispanics. Essential workers had an increased prevalence of SARS-CoV-2 infection compared to other occupations. Social distancing measures appeared to have contributed to decrease the morbidity by the end of 2020. Diabetes and older age jointly increased the risk of COVID-19 mortality (RERI=27.9 [95% CI = 24.0, 32.2]).

Conclusions. US Hispanics experienced excess COVID-19 morbidity and mortality. Older age and diabetes mellitus synergistically increased the risk of COVID-19 mortality.
The “Able” Hester and the “Inhuman” Cristina in The Scarlet Letter and Lives of the Saints
Authors: Han Wenjie
Published: July 2023

Published in 1850, Hawthorne’s masterpiece, The Scarlet Letter tells a story of Hester Prynne, who irretrievably breaks the law of Puritanism by giving birth to a girl through an affair with a local respectful priest named Dimmesdale and struggles to create a new life of repentance and dignity independently. Comparatively, Lives of the Saints, begins Nino Ricci’s trilogy centered on the experience of a southern Italian family in Valle del Soles before its emigration to Canada. Different from the other two novels, it focuses on the first seven years of Vittorio, living with his mother Cristina and his grandfather. The central plot of Lives of the Saints is the snakebite that Vittorio’s mother Cristina receives on her leg while she is in the stable of her father’s house, whereas later she is proved to be engaged in an adultery with a man, which is seen as a “pernicious and contagious illness”. This essay will explore the existential elements of the reaction to adultery of the two protagonists Hester and Cristina in Hawthorne’s The Scarlet Letter and Nino Ricci’s Lives of the Saints with some core concepts of existentialism to investigate that whether Cristina is the “Canadian Hester” with the great awakening.

Authors: Gaur Sagar
Published: July 2023

The role of the planning engineer is crucial for successful planning, monitoring, controlling of the project. The Indian construction industry lacks the ability to implement project controls and project management tools leading to tremendous delays. It is crucial that at least planning engineers should be deployed for each construction projects for transparent reporting to sr. management. Collaboration & Synchronization between various departments during the project life cycle can only be achieved 100% by having a planning engineer in the project organogram. The proper organization hierarchy is essential for the implementation of the role of planning engineer. Project Controls department must be introduced for better working of planning engineers. This study examines the obstacles faced by the Indian construction sector when implementing the role of planning engineer. This study uses a questionnaire survey, answered by the industry experts. There were 140 respondents. The questions related to effectiveness of planning engineers in the Indian construction industry were also covered. The responses conclude that the Indian construction industry is struggling in managing/implementing the role of planning engineer, thus, facing a biggest failure in getting the right reports at the right time that are delaying the projects in terms of cost, time & change of scope. The Indian construction industry must be more organized. Management should be more concerned about ensuring the proper implementation of roles, responsibilities & authority of planning engineer, follow international recommended guidelines like AACE for understanding in detail about the role & responsibilities of planning engineer, provide latest software to planning engineer for digitalization of reports and provide appropriately training at the required time.

The COVID-19 pandemic and its effect on human capital and financial performance: Evidence from Serbian banks
Authors: Pavlović Goran
Published: July 2023

Human capital holds significant importance for banks, as it includes specific knowledge and skills. It serves as a crucial determinant of financial performance. However, human capital is susceptible to various factors that can exert negative effects. The COVID-19 stands as one such factor, necessitating bank restructuring and potentially resulting in a depreciation of human capital value and subsequent performance decline. The objective of the research is to investigate the influence of the COVID-19 pandemic on the human capital of banks in the Republic of Serbia and evaluate its implications on financial performance. The research spanned across all banks operating in the Republic of Serbia throughout the period of 2019 to 2021. The Wilcoxon Signed Rank test was employed to assess the difference in human capital value over the observed period. Furthermore, the regression analysis was implemented to investigate the impact of human capital on ROA, ROE, and NPM. Results showed that COVID-19 pandemic has led to a decrease in the value of human capital in banks in the Republic of Serbia. The financial performance of banks is positively influenced by human capital in the short term. However, over the long term, the value of human capital depreciates, resulting in a diminishing impact on financial performance.

Published: July 2023

The goal of this study was the optimization of chromatographic conditions and validation of the isocratic RP-HPLC method for monitoring the stability of aripiprazole, identification and quantitative analysis of aripiprazole and its degradation products in tablets. In addition, robustness was tested by applying the methodology of experimental design. The forced degradation study of aripiprazole was conducted in accordance with the ICH guidelines. The stability of the active pharmaceutical substance was tested under the conditions of hydrolysis in acidic, neutral and basic environments, thermal degradation, oxidation and photolysis. The active pharmaceutical ingredient was degraded under oxidation conditions, and the identity of the resulting degradation product, N-oxide, was confirmed. Under the other conditions tested, the active pharmaceutical substance was found to be stable. The developed method RP-HPLC allowed the separation of degradation products and aripiprazole and was defined as a stability-indicating method. The proposed method was validated for qualitative and quantitative analysis of aripiprazole and its degradation products. Accordingly, selectivity, linearity, precision, accuracy, limit of detection, limit of quantification, and robustness of the method were tested. The Box-Behnken experimental design was used in robustness testing.
Dental age estimation using the pulp/tooth ratio in lower canines in population of Bosnia and Herzegovina
Authors: Srabović Amila , Zukić Selma , Jesenković Džan , Srabović Nedim
Published: July 2023

Background/Aim:Dental age estimation in adults is a challenging process due to the lack of sufficient information on the accuracy of dental methods applied in the identification of persons without information on identity. Previous studies on dental age estimation in adults suggested that each method should be tested on a population other than one which was used to develop the specific method. The aim of this study was to estimate dental age in adults from Bosnia and Herzegovina with the radiographic analysis of the pulp/tooth ratio of lower canines and to determine differences from chronological age. Material and Methods: The sample for the research comprised 50 periapical radiographs, with visible intact lower canine teeth, derived from an archive of the Department of Dental Morphology, Dental Anthropology and Forensics. After the selection process, all radiographs were digitalized. Additional information used is the chronological age and sex of the person to whom the images belonged. The measurements of the pulp space and the lower canine tooth were performed using the ImageJ computer methods. The results of measurements were entered in formulas for assessments of dental age, as per equations given by the authors. Results: The research has shown that there is a significant difference in examined population between the dental age estimated by the analysis of pulp/tooth ratio of lower canine teeth and the chronological age. The standard error of regression for Cameriere model was 14.12 years, and this model proved to be statistically significant (p= 0.0017). Kvaal-Solheim model from 1994 has shown a standard error of 15.07 years, and did not prove to be statistically significant (p= 0.054), while another model from 1995, by the same authors, shows a standard error of 14.64 years, and it proved to be statistically significant (p= 0.011). Conclusions: It is possible to estimate dental age by means of pulp/tooth ratio. However, it is necessary to conduct further research that will include a larger number of examinees and different age groups and also consider the specificity of teeth in Bosnia - Herzegovina's population to acquire more accurate data on accuracy and reliability of those methods in this population.

Background/Aim: The objective of this research was to evaluate the level of oral hygiene, the prevalence of caries, and the condition of the soft tissues in children and adolescents referred for their first orthodontic examination. Material and Methods: The research was conducted at the Department of Orthodontics of Sarajevo University - at the Faculty of Dentistry with the Dental Clinical Center. A total of 300 patients with mixed and permanent dentition who were referred for their first orthodontic examination were included in the study. The patients were offered to sign a Letter of Informed Consent for this study. All patients were assigned a Decayed, Missing, and Filled Teeth (dmft/DMFT) index. Periodontal indices were evaluated on all first permanent molars and all permanent central incisors. The periodontal indices included the determination of PI,CI,GI, PBI. Results: The results were processed with the application of standard statistical methods, by using the SPSS computer program for statistical analyses (SPSS-Statistical Package for Social Sciences) Version 21.0. The results of this study show a high dmft and DMFT indices in patients referred for orthodontic examination. The dmft index value in the respondents with mixed dentition was 3.0 (1.0 - 6.0). The DMFT index value in the respondents with permanent dentition was 4.0 (0.0 - 6.0), while in the respondents with mixed dentition, it was 1.0 (0.0 - 3.0). Our research also shows that out of 300 patients referred to an orthodontist for their first orthodontic examination, 250 of them (83.33%) have demonstrated an increased value of the Plaque index. Conclusions: The results of this research should be peculiarly alarming for pedodontists and general dentists, cautioning them to implement caries prevention measures more intensively and make referrals to an orthodontist only in case of those patients who have been cured previously.

Professional traineeship programme as a tool facilitating participation of unemployed youth in the labour market: Case study of the Republic of Serbia
Authors: Lebedinski Lara , Pavlović Dejana
Published: July 2023

Active labour market policies (ALMPs) aim to increase employment mainly targeting vulnerable groups as beneficiaries - long-term unemployed, youth, women, people with disabilities, Roma, etc. The prevalence of ALMPs and their intensity vary from country to country as determined by available financial resources, targeted beneficiaries' characteristics as well as the labour market characteristics. The objective of this paper is to examine the 12-month Professional Traineeship Programme (PTP) implemented by the National Employment Service (NES) of the Republic of Serbia. The programme was conducted from 2017 to 2018 assigning 9,561 participants to workplace training based on their educational background with a view to easing the transition from education to work. Our analysis illustrates the characteristics and labour market outcomes of the programme's participants. Every third participant got employed in the company after completing the programme, and after one year every second participant was employed (in the same company or elsewhere). We find that those who participated in the programme in the public sector were somewhat less likely to gain employment a year after its completion. Moreover, women were more likely to be employed one year after finishing the traineeship as well as those who were better educated and those who lived in more economically developed regions. Gender, education level and one's regional background are therefore found to be important correlates of success in securing employment when young people enter the labour market following education.
Humidity and air temperature predict post count on Twitter in 10 countries: Weather changes & LIWC psychological categories
Authors: Bojić Ljubiša , Mitrović-Dankulov Marija , Pantelić Nenad
Published: July 2023

There are many indications that weather conditions influence human life and well-being. Some of these indicators, such as the influence of weather on human health, have been explored in detail. On the other hand, the influence of daily fluctuations of different meteorological variables on the human psychological state still remains unknown. We apply combined methods from statistics, psychology, machine learning, and complex networks theory to explore the influence of weather parameters on different psychological categories of Twitter users in ten different countries. Our results show that the temperature, pressure, and humidity are highly correlated with Twitter users' activity, sense, and affect. Our comparative analysis for different countries shows that the strongest correlation was found for the USA, Italy, and Portugal, indicating differences between countries. However, our results show that the level of activity of Twitter users, described as Post Count, is strongly connected to changes in temperature and humidity in all countries. We use complex networks theory to explore these connections and differences between countries further. Our findings suggest that weather parameters can be used to predict Twitter users' activity and psychological manifestations, which can be beneficial to marketing and advertising.

Published: July 2023

In the modern society of science and technology, scientific literacy is viewed as one of the key educational competencies. However, research shows that young people's interest in natural sciences is very low, that the average achievement of our 15-year-olds in the field of natural sciences is significantly lower compared to the OECD average, but also that significantly higher results in the field of natural sciences are achieved by our fourth-grade pupils who were included in the preschool education program. The paper presents the results of the research aimed at examining preschool teachers' attitudes towards natural sciences and the development of scientific competencies in preschool children. The research goal defined in this way was operationalized in the following research tasks: 1) examine how preschool teachers assess their interest in natural sciences and their knowledge in the field of natural sciences 2) examine how preschool teachers assess children's interest in the phenomena from the field of natural sciences, 3) examine what they perceive as the greatest contribution from situations during which they explore together with children the phenomena that are the subject of natural sciences. A descriptive method was used, with surveying and scaling as research techniques. The research results showed that preschool teachers have a positive attitude towards natural sciences, that they highly value children's interest in natural sciences, that they view as the greatest contribution of situations during which children explore the phenomena studied in natural sciences in that they enable children to enjoy themselves and be happy, while the smallest contribution of these situations is perceived in developing children's interest in science. Such research results show that preschool teachers have a positive attitude towards the development of scientific competences, but that they need stronger support in understanding the essential importance of the development of scientific competences in working with children.

The application of the literary text as a starting point in the integrative approach in teaching in the first cycle of primary education is considered in this paper. A survey was conducted on a sample of 225 primary school teachers in order to determine the following: (1) whether they use a literary text as a starting point in the integrative approach in teaching; (2) how they evaluate their methodological competence during institutionalized training for the application of the literary text as a starting point in the integrative approach; (3) did they undertake further professional trainings in terms of methodology in this area and, if so, in what ways did they do it; (4) how they assess their methodological competence for the application of the literary text in this function. The obtained results show that 38.2% of the primary school teachers regularly and 57.3% occasionally use a literary text as a starting point for the integrative approach and that they consider the preparation that requires greater engagement (68.0%) as the greatest difficulty in applying this approach. They also believe that during their university training they were partially qualified (50.2%) to apply the literary text as a starting point in the integrative approach, but that they had the opportunity (92.4%) to expand their methodological knowledge on this topic, most often through seminars (56.44%), and they estimate, in the largest percentage (53.8%), that they are competent enough to implement such an approach in practice. In the conclusions, the need for further research in this area is stressed and it is implied that methodological courses at teacher education and pedagogical faculties should be enriched with the content on integration.

Circumstances arising after the proclamation of the COVID-19 pandemic indicate the need for a permanent change in the access to education in medicine, the use of online tools and flexibility in the application of innovative learning solutions. This study aimed to determine medical students' learning styles and to use this information to improve distance learning platforms in order to promote personalized learning performance. A prospective cohort study was conducted among medical students attending the Faculty of Medicine, University of Belgrade, who were enrolled in the obligatory Medical statistics and informatics (MSI) course during 2017-18 school year. The Index of Learning Styles (ILS) questionnaire was used to measure the dimensions of learning styles: Sensing/Intuitive, Visual/Verbal, Active/Reflective, and Sequential/Global. Additional data included demographic information and formal evaluation of student achievements. The existing online teaching approach supported by Moodle LMS was upgraded for upcoming 2020-21 school year to cover all student learning preferences. Four hundred sixty-two medical students were enrolled. Most students were female (64.5%); average age 21.4±1.1 years. The average problem solving and final statistics scores were 16.8±2.6 and 82.8±12.4, respectively. The dominant learning styles on the Active/Reflective and Sensing/Intuitive scales were active (74.9%) and sensing (50%). On the Visual/Verbal and Sequential/Global scales main learning preferences were neutral to visual (48.5% and 41.3%, respectively) and neutral to sequential (72.3% and 18.4%, respectively). The strong sensing learning style and age were significant predictors in multivariate regression models, with problem solving and final statistics score as dependent variables. Based on these findings, the existing learning platform has been upgraded to cover all learning preferences and personalize learning for students with learning styles other than sensing. Students with a strong sensing learning preference have a better academic performance in MSI. Better knowledge and understanding of students learning styles can aid instructors and curriculum designers to adjust teaching methods in order to help students gain their full academic potential during COVID-19 pandemic.
Komparativni i društveno-kritički pristup romanima Pupak sveta Venka Andonovskog i Dobri dani Marka Dinića u germanističkoj nastavi
Authors: Petrović-Jilih Marina
Published: July 2023

Building on the current scientific and literary-didactic discourse, this paper has as its subject the analysis of the group discussion and the categorization of the so-called functional literary competences which students of German language studies should master. The focus of dealing with literary texts in the eighth semester of the German language studies is, apart from their literary nature, primarily their socio-political impulses and influence on the transfer from the world of the text to the world around us. By comparing the two novels, The Navel of the World by Venko Andonovski and Dobri dani by Marko Dinić, and by means of their productive treatment in the classroom, we will see whether literary texts contribute to the development of the social-critical engagement of the recipients. Along with observing and defining the didactics of literature as an applied science and a part of the literary social system, qualitative scientific methodology was applied in this research. After the semi-structured group discussion procedure, the obtained data were analyzed and categorized. The research questions supported by theoretical postulates important for this paper arose from teaching practice, while methodological examples and research results bring it back to that practice.
Govorne aktivnosti na Padletu u okviru onlajn-nastave iz fonetike francuskog jezika namenjene srbofonim studentima
Authors: Radusin-Bardić Nataša
Published: July 2023

The goal of the paper is to present our experience in organizing speaking activities on Padlet as a part of online French phonetics exercises during the summer semester of 2020/21 at the Faculty of Philosophy, University of Novi Sad. The proposed activities on Padlet (oral presentation on a favorite Francophone song, destination, and film) were primarily aimed at determining possible phonetic-phonological and morpho-phonological students' mistakes in their oral presentation. The collected audio-corpus was analyzed using the perceptive and descriptive methods, where the teacher, after carefully listening to all the recordings, singled out the most common phonetic-phonological errors, which he/she would then point out to each student individually via electronic correspondence (in the form of a text and, if necessary, audio comments), followed by a unified analysis of the common mistakes and exercises based on the principle of the articulatory method of phonetic correction in synchronous online classes on Zoom. The analysis of the collected audio-corpus and the pedagogical implications of the obtained results are shown on the example of the typology of the most frequently observed mistakes in the production of nasal vowels (/ɑ͂/, /ɛ~/, /ɔ͂/). Our paper also presents the results of a qualitative research conducted among students on the use of Padlet for the above purposes, in which they spoke positively about this digital tool and gave us useful feedback that will help us in our future work.

The purpose of this study is to determine the effect size of gender on motivation towards science learning by combining the results of studies, which were conducted to determine the effect of gender on motivation towards science learning, via the meta-analysis method. In this context, master's thesis, doctoral dissertations, and articles, which were conducted between 2010 and 2020, were suitable for the research problem, and had statistical data to be included in the meta-analysis study, were reviewed and examined in Turkish and English from national and international databases. As a result of the literature review, 2435 national and international studies were collected. Forty-nine studies, containing data suitable for coding protocol in accordance with the criteria determined by the researchers, were included in the meta-analysis. The sample size of 20.862 participants was obtained in the study (10.446 females and 10.416 males). The effect sizes and the combined effect sizes of the studies were calculated using "Comprehensive Meta-Analysis v 2.0 (CMA)." In the studies using the random effects model, the effect size of the gender variable on motivation towards science learning was determined to be 0.155 (95% CI, SE = 0.040). This value showed that the overall effect of the gender variable on motivation towards science learning was at an "insignificant" level in favor of the women. The results of the anova similarity analysis performed for the categorical moderators of publication type, scale type, and education level indicated that these moderators did not cause any statistically significant difference in the effect sizes. As a result of the meta-regression analysis performed for the publication year moderator - which was evaluated as a continuous variable - this moderator did not make any significant difference on the effect sizes of motivation towards science learning.
Strukturisanje pravougaonika kod učenika mlađeg školskog uzrasta
Authors: Milošević Mila , Đokić Olivera
Published: July 2023

U radu se bavimo problemom prostornog strukturisanja kao mentalne operacije organizovanja 2D ili 3D prostora putem ortogonalnih mernih jedinica. S jedne strane, istraživanja pokazuju da učenici imaju poteškoća da sagledaju površ pravougaonika u terminima redova i kolona. S druge strane, ova mentalna aktivnost je ključna za pojmovno razumevanje merenja površine, ali i za druge oblasti u početnoj nastavi matematike. Cilj i zadaci rada odnose se na ispitivanje i klasifikaciju strategija prostornog strukturisanja pravougaonika pre formalnog učenja površine. Intervjuisano je devetoro dece mlađeg školskog uzrasta tokom perioda pandemije virusa Kovid-19. Kvalitativna analiza video-zapisa individualnih intervjua ukazuje na to da učenici imaju različite strategije prostornog strukturisanja zavisno od razvojnog nivoa kome pripadaju i konteksta zadatka. Strategije učenika su sagledane u svetlu teorije hijerarhijskog interakcionizma i pristupa učenju zasnovanog na trajektorijama učenja prema kome je učenje integrativan i postepen proces koji se odvija kroz nivoe mišljenja. U radu je dat predlog praktičnih aktivnosti sa ciljem učenja merenja površine. Na kraju, skrećemo pažnju na dva važna problema matematičkog obrazovanja: prenaglašenost rada sa diskretnim veličinama u osnovnoškolskoj nastavi matematike i nedostajanje povezanosti nenumeričkog (geometrijskog) i numeričkog razmišljanja o površini.
