THE STATE OF THE FINANCIAL MARKET OF UKRAINE DURING THE PANDEMIC COVID-19 AND THE REALITIES OF TODAY
Authors: Tataryn Nataliia , Kolba Renata
Published: August 2021

In the article, it is feasible to analyze the impact of the coronavirus on the financial sector of Ukraine as of 2021. The pandemic has become a real test both for the financial market of Ukraine and for the entire economic situation of our country. In particular, the first part analyzed the impact of the pandemic on the main macroeconomic indicators of the market. We determined that during the period from sowing to May last year, Ukraine's GDP decreased by five points, which negatively affected macroeconomic indicators and the general well-being of our population. The next one analyzed the macroeconomic indicators characterizing the state of the Ukrainian market, experienced the greatest float of COVID-19. We have determined that wages have undergone a sharp cut, which has decreased by 10% over several months. The next was the analysis of the inflation index, which increased during the quarantine period in March, but since April 2020 it has begun to file, due to the end of strict quarantine restrictions. The impact of the coronavirus on the exchange rate was also studied, which in April 2020 the dollar exchange rate began to fall, but since June we have seen its rapid growth. Next, we analyzed the NBU's foreign exchange interventions, it can be seen that in July 2020 the NBU began selling foreign currency to support the national hryvnia exchange rate. In general, during the quarantine period, the NBU sold $ 1,160,000,000 in order to support the hryvnia. Enterprises in connection with punishing them with restrictions were forced to issue stocks and bonds in order to stay afloat. As a result, we can safely say that the coronavirus epidemic had a negative impact on the financial market of Ukraine and left a "black spot" on the economy of our state. It can be concluded that the situation with the pandemic does not bode well not only for the Ukrainian market, but also for the economy as a whole, and if this virus continues to develop, the hryvnia exchange rate may collapse. To date, the consequences of the infection have caused a serious disruption in the Ukrainian economy. In this situation, one can only hope that Ukrainian exports will grow in positive dynamics, which will allow our state to receive stable financial flows in foreign currency and in accordance with strengthening its own rate.

Published: August 2021

Objective: The objective was to quantify the morphological diversity of Calophyllum brasiliense Cambes from four municipalities of the State of Tocantins employing morphological characteristics, to strengthen information on conservation and future breeding of the species.
Methodology: Seeds were collected from four municipalities in the State of Tocantins and one in the State of São Paulo. The following were evaluated: plant height, stem diameter, root length, number of leaves, leaf area, root dry mass, shoot dry mass, total dry mass, and Dickson´s quality index. The data were subjected to univariate analysis of variance, Tocher grouping method, and UPGMA, obtaining a dendrogram through the generalized Mahalanobis distance.
Results: The results showed a statistical difference of 1 and 5% probability. Dueré stood out in stem diameter(5.52 mm), Sandolandia in height (34.84 cm) and root length (42.13 cm). Formoso stood out in the number of leaves (34 leaves). Lagoa da Confusão in leaf area (856.28 cm 2 ) and São Paulo in root dry mass (16.20 g), shoot dry mass (12.38 g), total dry mass (16.20 g), and Dickson´s quality index (1.57). Implications: Variations in morphological characteristics can be used as a tool for genetic studies of guanandi progeny accordingto their similarity and/or differences.
Conclusions: The morphological divergence evidenced that among the five studied areas it is possible to direct the collection of seeds to subsidize conservation strategies and future breeding of the species.
Scientific mapping of the knowledge on the El Cielo Biosphere Reserve
Authors: Caballero Rico Carmina
Published: August 2021

Abstract: The current knowledge base of the El Cielo Biosphere Reserve (RBC), Tamaulipas, Mexico is identified from scientific publications between 1993 and 2019.
Objective: Analyze, synthesize and categorize the studies published on El Cielo Biosphere Reserve (RBC), Tamaulipas.
Design/methodology/approach: The methodology focused on the search, classification, and review of existing sources in the SCOPUS database from the perspective of the knowledge base. The study covered 37 publications that were analyzed considering scientific mapping in four dimensions: size, time, space, and composition. The analyses were performed using the Bibliometrix and Biblioshiny software tools.
Results: It was found that the reviewed publications address biodiversity studies from a disciplinary approach and from an ecological perspective, which produces a fragmented knowledge of the territory and its problems.
Limitations on study/implications: It is recognized that there may be publications that do not appear in the Scopus database
Findings/conclusions: Knowledge about the El Cielo Biosphere Reserve is fragmented, with a disciplinary approach and from an ecological perspective. The lack of a critical mass of researchers to generate useful knowledge was observed. A weak intellectual structure was also found, which generates a reduced contribution to the conservation of biodiversity. The original contribution of this paper is the synthesis of the current state of knowledge about biodiversity conservation of the El Cielo Biosphere Reserve, which had not been performed previously.

Published: August 2021

Objective: Determine current and potential distribution of S. tacaco in Costa Rica with seven Species Distribution Models (SDM), in order to optimize the management of S. tacaco genetic resources, aimed at identifying patterns of geographic distribution and possible climatic adaptations allowing to have perspectives on their conservation and genetic breeding.
Design/Methodology/Approach: 21 points of occurrence together with 19 bioclimatic variables and altitude were used to evaluate seven machine learning models and an assembly of these. Open-source libraries running in Rstudio were used.
Results: Distribution models were inferred by the variables bio1, bio2, bio3, bio4, bio12, bio13, bio14, bio18 y bio19. The generalized additive model obtained the highest values ??of area under the curve (0.96) and True skill statistic (0.90), however, the seven models tested and the assembly showed adequate performance (AUC> 0.5 and TSS> 0.4). Bioclimatic variables related to temperature were the ones with the greatest contribution to the models and the main limitations in the distribution of S. tacaco.
Study limitations/implications: Possibly a greater number of occurrence points are required to evaluate distribution models.
Findings/Conclusions. Areas with high potential distribution suitability for S. tacaco are found in central valleys of Costa Rica, covering regions of the provinces of Alajuela, Cartago, San José and Puntarenas. These areas can be sources of germplasm for future conservation and breeding studies.
A Method for Deriving High-Priority Financial Data Items that Must be Improved to Increase Market Capitalization.
Authors: Tsuyoshi Yoshioka
Published: August 2021

Market capitalization is one of the most important indicators for gauging the value of a company. Normally, improving financial data increases market capitalization. However, because there are numerous financial data, it is important to derive high-priority financial data items whose improvement can increase market capitalization. To achieve this, in this study, a method was developed using a remodeled customer satisfaction analysis model with financial data of the companies that make up the Nikkei 225. A graph was created with the correlation coefficient on the horizontal axis and the deviation value of each financial data item on the vertical axis, and then the financial data items plotted in the lower right corner of the graph were extracted. Using this method, it is possible to derive high-priority financial data items to increase market capitalization from numerous financial data.

Front Page Challenge: A case study examining what the ethnic media promises and what it delivers
Authors: Lindgren April
Published: August 2021

The editors and publishers of ethnic newspapers acknowledge the importance of reporting local news in helping their readers understand Canadian society. Yet detailed analyses of news content produced by ethnic media organizations often find that information that fosters understanding of life in Canada takes second place to news from the group‟s home country. This study investigates the local news content published about the Greater Toronto Area in the Chinese-language newspaper Ming Pao(Toronto-area edition) and identifies a significant imbalance in the mix of local news versus homeland news from China, Taiwan, and Hong Kong. The author argues that newcomers trying to understand their adopted place would benefit from access to more extensive and varied local news and suggests that providing journalists who work in ethnic news media with greater opportunities for professional development would be one way to achieve this goal. Programs could include journalism skills workshops as well as seminars that explore the role of local news in helping immigrants adapt. Professional development sessions would also bring together journalists from different ethnocultural communities to discuss the challenges they face, develop joint projects, and acquaint editors and publishers with the latest research on the role of local news in fostering intercultural understanding.
Shared Experiences

During the academic year 2018 – 2019, the Department of Languages and Literatures at the University of North Carolina - Asheville (UNCA) launched a pilot curriculum in Intercultural Education for intermediate-level foreign language students in French, Spanish and German. It was decided early on to adopt a performative/experiential approach, and to accompany the project with an empirical study based on qualitative data. This article lays out the parameters and contexts of the project itself and summarizes the findings of the accompanying study, including an articulation of questions that remain for future exploration. The article closes with a broader reflection on the place of such work in foreign language study and in the modern university, as well as in the context of the present (as of this writing) corona-virus pandemic.
PERSONALITY VARIABLES IN RELATION TO THE EFFECT OF FEEDBACK ON THE EFFECT OF OVERCONFIDENCE
Authors: Krause Robert
Published: August 2021

This research examined which personality variables potentially moderated the effect of feedback on the Overconfidence effect. Research sample consisted of Slovak teachers (n = 223) from across school levels, who were randomly allocated into one of the three groups, out of which two were experimental and one was control. Each group of participants filled in three personality questionnaires, the Reading Literacy Test, and questions on the Overconfidence effect. The first experimental group was given a real feedback on their achieved performance, the second experimental group was given an inaccurate feedback and the control group did not receive any feedback. It was pointed out that despite high mutual correlation between chosen personality variables, no relation was demonstrated between the Overconfidence effect and optimism, neuroticism, or participant’s self-evaluation. The results show that the impact of real feedback on the Overestimation effect depends on the level of neuroticism. Results suggested that the type of feedback on the Overconfidence effect is not moderated by the level of optimism. At the same time, the impact of real feedback on the Overconfidence effect is partially moderated by the level of self-evaluation and the impact of inaccurate feedback on the Overconfidence effect is not moderated by the level of self-evaluation.
Keywords: moderation analysis, overconfidence effect, effect of experience, personality variables

Published: August 2021

Cohesive speech has commonly become regarded as one of the essential aspects of language development, especially for pre-schoolers. This study aimed to shed light on the cohesive speech of pre-schoolers (CSP) knowledge base. Three hundred ninety-five publications close related cohesive speech research of 5-6-year-old children were collected from the Scopus database. By using the bibliometric approach, the results showed the growth rate of publications over time from 1970 to 2020. In this period, the top five countries, the United States, the United Kingdom, Australia, Brazil and France, have published over 60% of total documents. Besides, four main interests of authors in this field were discovered: “language development”, “speech pathology outcomes”, “speech therapy”, “language intervention”. Among these themes, “speech pathology outcomes” was the most relevant one. Another finding, in recent years, scholars focused on aspects of autism spectrum disorder of pre-schoolers. More importantly, the achievements of this discipline have considerably made positive contributions to various fields both in terms of theory and practice, especially in language and linguistics, speech and hearing, psychology, and medicine. Overall, these studies highlight the need for many other studies, particularly relevant to pre-schooling when new generations should be better prepared to be happy in school by their future cognitive developments.

STUDENT MISBEHAVIOUR, TEACHER SELF-EFFICACY, BURNOUT AND JOB SATISFACTION: EVIDENCE FROM CROATIA
Authors: Vidić Tomislava , Đuranović Marina , Klasnić Irena
Published: August 2021

Student misbehaviour is an increasing problem of contemporary school. The aim of this research was to examine the extent to which teachers perceive student misbehaviour, how self-efficient they are, how satisfied they feel with support from their environment and with the teaching job itself, and to which extent they experience the burnout syndrome. The research included 603 primary and secondary school teachers in the Republic of Croatia, and it found quite low, but significant negative correlations between student misbehaviour and teachers’ self-efficacy, personal accomplishment, and job satisfaction. Besides, positive correlations between student misbehaviour and teacher burnout were also proven. Statistically significant differences between primary and secondary school teachers were found in their experience of student misbehaviour, dealing with adversities related to student misbehaviour and provided support from expert associates. The results of regression analysis indicate that the overall misbehaviour and satisfaction with help from parents significantly contribute to satisfaction with the teaching profession, and emotional exhaustion and depersonalization lead to decrease of job satisfaction. The results also indicate that demographic characteristics, namely years in service and the type of school, do not contribute to the explanation of neither burnout nor job satisfaction. The implications applicable in practice could relate to the need for preventing student misbehaviour and empowering teachers, regardless of their in-service years and the type of school they work at. Keywords: burnout, classroom management, job satisfaction, quantitative methodology, self-efficacy

Primary cutaneous anaplastic large cell lymphoma (pcALCL), a hematological neoplasm caused by skin-homing CD30+ malignant T cells, is part of the spectrum of primary cutaneous CD30+ lymphoproliferative disorders. To date, only a small number of molecular alterations have been described in pcALCL and, so far, no clear unifying theme that could explain the pathogenetic origin of the disease has emerged among patients. In order to clarify the pathogenetic basis of pcALCL, we performed high-resolution genetic profiling (genome/transcriptome) of this lymphoma (n=12) by using whole-genome sequencing, whole-exome sequencing and RNA sequencing. Our study, which uncovered novel genomic rearrangements, copy number alterations and small-scale mutations underlying this malignancy, revealed that the cell cycle, T-cell physiology regulation, transcription and signaling via the PI-3-K, MAPK and G-protein pathways are cellular processes commonly impacted by molecular alterations in patients with pcALCL. Recurrent events affecting cancer-associated genes included deletion of PRDM1 and TNFRSF14, gain of EZH2 and TNFRSF8, small-scale mutations in LRP1B, PDPK1 and PIK3R1 and rearrangements involving GPS2, LINC-PINT and TNK1. Consistent with the genomic data, transcriptome analysis uncovered upregulation of signal transduction routes associated with the PI-3-K, MAPK and G-protein pathways (e.g., ERK, phospholipase C, AKT). Our molecular findings suggest that inhibition of proliferation-promoting pathways altered in pcALCL (particularly PI-3-K/AKT signaling) should be explored as potential alternative therapy for patients with this lymphoma, especially, for cases that do not respond to first-line skin-directed therapies or with extracutaneous disease.

Los repositorios institucionales desarrollados por las universidades son infraestructuras necesarias para garantizar el acceso a la literatura científica a toda la ciudadanía. Argentina, desde 2013, dispone de una ley nacional que insta a las entidades del sistema de ciencia y tecnología a generar repositorios de acceso abierto y a sus investigadores a depositar allí una copia de su trabajo. En este artículo se analiza su desarrollo y evolución en las universidades nacionales argentinas en relación con las políticas públicas implementadas a nivel nacional, las cuales se detallan en una cronología. A través de la observación directa de los sitios web de las universidades, se identifican los repositorios y otras iniciativas de acceso abierto y se sistematiza la información. Luego, mediante entrevistas, se indaga la perspectiva y opinión de sus gestores para conocer los modos en que se interrelacionan las políticas públicas con las realidades institucionales. Finalmente, se discute y reflexiona acerca de las particularidades de los repositorios en la coyuntura institucional y política.

Trophic structure and resource utilization of the coastal fish community in the western Wadden Sea: evidence from stable isotope data analysis
Authors: Poiesz SSH , Witte JIJ , van der Meer MTJ , van der Veer HW , Soetaert KER
Published: August 2021

We studied the trophic structure of the western Wadden Sea fish community through stable isotope analysis (δ13C and δ15N) of 1658 samples from 57 fish species collected between 2012 and 2016. Stable isotope values differed between species but did not vary between years or seasons, and only for some species with fish size. Stable isotope values were not different between immigrating (spring) and emigrating (autumn) fish, suggesting a similar trophic niche of the various fish species in the coastal zone and inside the Wadden Sea. For the majority of species, average δ13C values were within the range of -12 to -20.5‰, showing that both (marine) pelagic and benthic primary producers were at the base of the food web. Average δ15N values varied among species from 13-18‰, resulting in estimated trophic positions (TPs) of 2.1-5.5 with the majority between 2.2 and 3.5. Thick-lipped grey mullet Chelon labrosus, golden grey mullet C. aurata, greater pipefish Syngnathus acus and pilchard Sardina pilchardus had the lowest TP (2.2-2.4). Among the common species (>10 observations), the highest TP values (3.4-3.5) were found for twaite shad Alosa fallax, smelt Osmerus eperlanus, bull-rout Myoxocephalus scorpius, bass Dicentrarchus labrax and cod Gadus morhua. For all species, estimated TPs based on isotope values were lower than those based on stomach content composition (2.0-4.7), which could be explained by species-specific differences in trophic fractionation or by underestimation of the contribution of smaller prey species in the stomach content analysis. The trophic niche space of benthopelagic species was the smallest and overlapped with that of the pelagic and benthic species. In terms of area use, trophic niche space was smaller for juvenile marine migrant species (nursery-type species) and overlapped with that of the (near-)resident species and marine seasonal visitors. Potentially, trophic competition is highest for the functional group of benthopelagic species and the guild of juvenile marine migrant species (nursery-type species).

Profesi guru bagi anak berkebutuhan khusus yang dikenal dengan sebutan Guru Pendamping Khusus (GPK) tidak lepas dari tekanan stres. Stres dapat berdampak negatif pada kinerja untuk itu GPK perlu mengembangkan suatu strategi coping yang efektif, agar dapat melewati stres yang dialami dan tetap memiliki kualitas kerja yang baik. Penelitian ini bertujuan mengeksplorasi peran dan tanggung jawab GPK, memahami situasi yang menimbulkan stres kerja, dan menganalisis strategi coping dalam menghadapi stres yang timbul. Peneliti menggunakan metode penelitian kualitatif dengan pendekatan fenomenologis. Peneliti menggunakan manajemen resiko sebagai alat analisis untuk memetakan peluang terjadinya stres yang menjadi nature dari profesi pengajar ABK. Mitigasi yang efektif diharapkan dapat meminimalisir dampak stress, baik untuk sumber stress yang terprediksi yang tidak terprediksi. Metode pengambilan sampel adalah strategi purposive sampling yang mencakup 10 guru pendidikan khusus dari 4-unit yang berbeda di Departemen Special Education Sekolah SPK Penyelenggara Pendidikan Inklusif di Jakarta Selatan. Temuan menunjukkan bahwa ada 5 sumber stres kerja yang utama, yaitu (1) kombinasi beban kerja dan tekanan waktu, (2) perilaku tantrum / sulit dari siswa ABK, (3) kurangnya kompetensi guru (pengetahuan / pengalaman / kemampuan dalam mengajar dan menghadapi ABK), (4) faktor orang tua siswa (tidak kooperatif/sulit), dan (5) hubungan interpersonal antar rekan guru. Para GPK menggunakan berbagai strategi coping sebagai alat mitigasi dengan pendekatan problem-focused dan emotion-focused sesuai sesuai dengan kondisi yang dialami.

Robin Criterion on Divisibility
Authors: Vega Frank
Published: August 2021

Robin criterion states that the Riemann Hypothesis is true if and only if the inequality $\sigma(n) < e^{\gamma } \times n \times \log \log n$ holds for all $n > 5040$, where $\sigma(n)$ is the sum-of-divisors function and $\gamma \approx 0.57721$ is the Euler-Mascheroni constant. We show that the Robin inequality is true for all $n > 5040$ which are not divisible by any prime number between $2$ and $953$. We prove that the Robin inequality holds when $\frac{\pi^{2}}{6} \times \log\log n' \leq \log\log n$ for some $n>5040$ where $n'$ is the square free kernel of the natural number $n$. The possible smallest counterexample $n > 5040$ of the Robin inequality complies that necessarily $(\log n)^{\beta} < 1.2592\times\log(N_{m})$, where $N_{m} = \prod_{i = 1}^{m} q_{i}$ is the primorial number of order $m$ and $\beta = \prod_{i = 1}^{m} \frac{q_{i}^{a_{i}+1}}{q_{i}^{a_{i}+1}-1}$ when $n$ is an Hardy-Ramanujan integer of the form $\prod_{i=1}^{m} q_{i}^{a_{i}}$.

Objectives: Good oral heath not only promotes an individual to look and feel good, it also helps in preserving oral functions. The study was carried out to assess oral health knowledge and practices, attitudes as well as their oral hygiene habits among university students in the UAE.
Method: A structured and revised questionnaire was distributed to 300 university students that were randomly sampled from the selected universities of the UAE. The questionnaires were answered anonymously by the students and paper consisted of questions to study and assess the prevalence of oral diseases amongst these students. The answers were then subjected to statistical analysis to determine if there is a significant correlation between oral health knowledge and attitude.
Results: Data showed a positive correlation with a Pearson coefficient value of 0.4 given at a positive gradient when plotted as a linear graph. The students had good knowledge on the basic oral health measures but still students had poor oral health practices they brush their teeth once daily and brushed for less than the optimal time of two minutes. Lack of time and cost were reported to be the most common causes that prevented visiting the dental clinic. While some students reported no importance to visit the dentist if there is any pain as the second most common reason.
Conclusion: Students had good knowledge on the basic oral health measures but efforts towards spreading proper dental education is very important to minimize and prevent the escalation of oral diseases that may develop due to lack of correct dental knowledge. Oral health education programs should be conducted with reinforcement to close the gap between knowledge and practice.

Published: August 2021

Self-awareness is an essential concept in physiology and psychology. Accurate overall self-awareness benefits the development and well being of an individual. The previous research studies on self-awareness mainly collect and analyze data in the laboratory environment through questionnaires, user study, or field research study. However, these methods are usually not real-time and unavailable for daily life applications. Therefore, we propose a new direction of utilizing lifelog for self-awareness. Lifelog records about daily activities are used for analysis, prediction, and intervention on individual physical and psychological status, which can be automatically processed in real-time. With the help of lifelog, ordinary people are able to understand their condition more precisely, get effective personal advice about health, and even discover physical and mental abnormalities at an early stage. As the first step on using lifelog for self-awareness, we learn from the traditional machine learning problems, and summarize a schema on data collection, feature extraction, label tagging, and model learning in the lifelog scenario. The schema provides a flexible and privacy-protected method for lifelog applications. Following the schema, four topics were conducted: sleep quality prediction, personality detection, mood detection and prediction, and depression detection. Experiments on real datasets show encouraging results on these topics, revealing the significant relation between daily activity records and physical and psychological self-awareness. In the end, we discuss the experiment results and limitations in detail and propose an application,Lifelog Recorder, for multi-dimensional self-awareness lifelog data collection.
Purinergic Signaling in Liver Pathophysiology
Authors: Jain Shanu , Jacobson Kenneth A.
Published: August 2021

Extracellular nucleosides and nucleotides activate a group of G protein-coupled receptors (GPCRs) known as purinergic receptors, comprising adenosine and P2Y receptors. Furthermore, purinergic P2X ion channels are activated by ATP. These receptors are expressed in liver resident cells and play a critical role in maintaining liver function. In the normal physiology, these receptors regulate hepatic metabolic processes such as insulin responsiveness, glycogen and lipid metabolism, and bile secretion. In disease states, ATP and other nucleotides serve as danger signals and modulate purinergic responses in the cells. Recent studies have demonstrated that purinergic receptors play a significant role in the development of metabolic syndrome associated non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), fibrosis, hepatocellular carcinoma (HCC) and liver inflammation. In this concise review, we dissect the role of purinergic signaling in different liver resident cells involved in maintaining healthy liver function and in the development of the above-mentioned liver pathologies. Moreover, we discuss potential therapeutic strategies for liver diseases by targeting adenosine, P2Y and P2X receptors.
