The immunometabolic gene N-Acetylglucosamine Kinase (NAGK) is uniquely involved in the heritability of multiple sclerosis severity
Authors: Nataf Serge
Published: November 2023

The clinical severity of multiple sclerosis (MS), an autoimmune disorder of the central nervous system, is thought to be determined by environmental and genetic factors. In their genome wide association study (GWAS), Harroud et al.1 identified a single nucleotide polymorphism (SNP), rs10191329, which is associated with MS severity in two large independent cohorts of MS patients. Different approaches were followed by the authors to prioritize the targeted genes which are transcriptionally regulated by such a SNP. It was concluded that the identified SNP regulate a group of proximal genes involved in brain resilience and cognitive abilities rather than immunity. Here, by conducting an alternative strategy for gene prioritization, we reached the opposite conclusion. According to our re-analysis, the main target of rs10191329 is N-Acetylglucosamine Kinase (NAGK), a metabolic gene recently shown to exert major immune functions.

Examining the influence of social media marketing on purchase intention: The mediating role of brand image
Authors: Ali Imran , Naushad Mohammad
Published: November 2023

Social media has revolutionized how businesses connect with consumers, going beyond product promotion to understanding consumer preferences. It is undeniable that social media plays a pivotal role in shaping consumer purchase decisions, as more individuals turn to these platforms to seek advice and opinions from peers. The current study engaged 410 Indian consumers, employing a quantitative approach backed by rigorous statistical methods, including descriptive statistics, correlation analysis, regression analysis, and structural equation modeling (SEM) using AMOS software. The goal was to unravel the intricate dynamics between social media marketing, brand image, and purchase intentions. The findings highlight a significant and positive relationship between social media marketing efforts and brand image perception. Moreover, it was discovered that brand image significantly influences consumers’ purchase intentions. Surprisingly, it did not find a direct and significant impact of social media marketing on purchase intentions.Notably, the study revealed a crucial insight: the influence of social media marketing on purchase intentions is fully mediated by the perception of brand image. In light of these results, businesses are encouraged to establish a strong presence on social media platforms to effectively promote their products and services. Organizations can effectively steer consumer purchase intentions by harnessing the synergy between social media marketing and brand image.

Authors: Alzghoul Amro , Abu lehyeh Salman , Ali Theeb AlNawafleh Enas , Abdulraheem Ali Alsheikh Ghaith
Published: November 2023

The objective of this study is to investigate the impact of servant leadership on employee well-being in the Jordanian hospitality sector. Furthermore, it attempted to explore the potential mediation effects of job burnout, role overload, and anxiety on this relationship. The data in this study were obtained from a sample of 341 individuals who were employed in five-star hotels located in Amman using a simple random sample. For analysis, the study employed the SEM-AMOS software. The results indicated a noteworthy and favorable influence of servant leadership on the well-being of employees (p = 0.001), emphasizing its crucial meaning in creating a nurturing work atmosphere that promotes enhanced well-being among employees. Additionally, the study has identified anxiety and job burnout as a mediator (p = 0.001), indicating that servant leadership has an impact on well-being by reducing levels of anxiety and job burnout. Nevertheless, the hypothesized mediating effect of role overload was not supported (p = 0.070) in the specific setting under investigation. The study’s theoretical implications contribute to the broader comprehension of the complex connections between servant leadership, employee well-being, and mediating variables. Furthermore, it provides empirical insights within the specific context of the Jordanian hospitality business.
Economic growth of Ukrainian regions and determinants of financial resilience: Modeling the causal nexus
Authors: Mulska Olha , Storonyanska Iryna , Patytska Khrystyna , Ivaniuk Ulana , Voznyak Halyna
Published: November 2023

Stable economic progress and upward dynamics of economic growth in the regions depend on their level of security and ability to withstand adverse macroeconomic and other shocks, as well as the state of affairs in which risks cannot be transformed into threats and dangers. The study aims to assess the causal nexus and the level of sensitivity of regional economic growth components to changes in financial resilience determinants. The research methods include systemic and structural analyses (building an information and analytical model for studying financial resilience), Granger test (identifying causal relationships between the variables under study), risk theory (studying the nature of fluctuations), and spatial and temporal approach. Data from the regions (oblasts) of Ukraine between 2015 and 2021 form the informational and analytical basis of the study. The paper reveals that the targeted use of transfers for socio-economic progress, increasing investment capacity, and bolstering financial and budgetary autonomy through increasing local budget revenues are the dominant financial determinants of regional economic growth. The results show that the most dominant causal nexus exists between (1) budgetary efficiency, interest rates on consumer/mortgage loans, and SME development, (2) the volume of loans/deposits and labor market efficiency and SME development, and (3) innovation development and foreign economic cooperation. Intensification of investment activity is crucial for ensuring real changes in the economic structure of all regions, particularly outsiders, accelerating transformation processes, mitigating regional economic divergence, and increasing competitiveness.
AcknowledgmentsThe study was conducted within the framework of the “Financial Determinants of Ensuring Economic Growth of Regions and Territorial Communities based on Behavioral Economics” project (№ 2020.02/0215) funded by the National Research Foundation of Ukraine (Competition “Support for Research of Leading and Young Scientists”).

USE OF ARROWS IN THE CONTEXT OF LEARNING IN CHEMISTRY AND THE IMPORTANCE OF ITS SYMBOLISM. The representation of arrows in Chemistry learning is routinely applied in classrooms and textbooks. Arrows of different shapes like horizontal, curved, vertical, or wavy have been used as symbols since the beginning of ancient civilizations, representing elements or compounds. The arrow is one of the most used symbols in Chemistry, as different types have presented different functions, especially in chemical reactions, and because there is no consensus, their use has generated ambiguities and confusion when applying them. In this sense, the present work sought to present and differentiate the types of arrows used in Chemistry to provide a better understanding of this symbol in the learning process. Furthermore, a historical overview of the emergence of arrows in the world of chemistry and the process of acceptance as chemical symbolism in chemical reactions is provided. The use of arrows in some chemical phenomena (e.g., resonance, tautomerism, symmetry operations, and movement of electrons) is also detailed. This work reflects that arrows, as chemical symbolism, require an increasingly concrete standardized notation system to avoid ambiguities of concepts. Finally, when using them, let us consider why the arrow is being symbolized and, above all, what is the scientific concept behind its symbolism.

CONTRIBUTIONS OF FEDERAL INSTITUTES TO THE DEVELOPMENT OF INITIAL GRADUATION OF CHEMISTRY TEACHERS IN BRAZIL. Federal institutes work in the formation of chemistry teachers, since the implementation of Law 11.892 of 2008, which created the Federal Institutes of Education, Science and Technology. In this study, we sought to know, through data found on the e-MEC and INEP platforms, the vacancies, flow of formation in chemistry and the formation of chemistry teachers in federal institutes and compare their role with public universities from Brazil. In view of the data, it was possible to perceive that the federal institutes offer 30% of the training of chemistry professionals, and 34% of the vacancies in chemistry teacher’s degree. It can still be seen that this advance in vacancies has taken place in the last 14 years. Another point observed was the training flow, in which the number of enrollees was analyzed in relation to the number of graduates over a period of up to 5 years. The data show that federal institutes have an average of 25% of graduates, which is higher than the average of public universities. Thus, we can say that federal institutes play a satisfactory role in the offer of vacancies and in the formation flow, when compared to public universities.
A reziliencia értelmezési kereteinek és lehetséges vizsgálati módszereinek összefoglalása a turizmusban
Authors: Debreceni János , Fekete-Frojimovics Zsófia
Published: November 2023

A turizmus ágazat vállalkozásai 2020 tavasza óta több nemkívánatos és kedvezőtlen időszakkal voltak kénytelenek szembenézni. Azt a képességet, hogy a szervezet képes-e a nemkívánatos esemény közepette változatlanul vagy a körülményekhez újszerűen alkalmazkodva tovább működni, a reziliencia jelöli. Jelen tanulmány a reziliencia szerteágazó fogalmi és értelmezési keretét foglalja össze a turizmus kontextusában. Bár a Covid19 közvetlen, kedvezőtlen hatása már a múlté, a turizmus több szakágazata jelenleg is válságos életképet mutat. A szálláshely-szolgáltatás, valamint az utazásszervezés- és közvetítés forgalma jelen­tősen elmarad a 2019. év értékektől. A vendéglátás szakágazatának bevételei pedig megközelítik ugyan a válság előttit, de a vállalkozások és üzletek száma jelentősen csökkent. A szakirodalom szisztematikus feldolgozása nem csak a jelenlegi helyzet megértése miatt hasznos, hanem hatékony megküzdési stratégiával szolgálhat egy újabb válságos időszakra. Bár a válság lefolyása és hatása egye­lőre megjósolhatatlan, a nemkívánatos körülmények alkalmat teremtenek a turisztikai vállalkozások ellenállási képességének valós idejű vizsgálatára. Ezért jelen tanulmány a reziliencia vizsgálati és mérési javaslatait is bemutatja.
Assessing Global Competitiveness: A Comparative Analysis of Financial Institutions Development through the Global Competitiveness Index
Authors: Sallai Dóra
Published: November 2023

This study aims to investigate the relationship between a country’s financial development and its global competitiveness, specifically focusing on financial institution efficiency. The research utilizes the Global Competitiveness Index (GCI) and the Financial Market Development Index Dataset as primary sources, covering the period from 2007 to 2019. Additionally, the study seeks to analyse and compare the rankings of European Union (EU) member countries and the United Kingdom in terms of the financial markets pillar of the GCI, while also examining the disparities between the “old” GCI and GCI 4.0. This study focuses specifically on the eighth pillar of the GCI, namely “Financial mar­ket development”. It emphasizes the significance of an efficient financial sec­tor in allocating resources, facilitating business investment, and fostering pro­duc­tivity. A sophisticated financial market, encompassing elements such as sound banking, regulated stock exchanges, and venture capital, plays a pivotal role in driving private sector investments. Transparency, credibility, and ade­quate regulation within the banking sector and financial markets are essential for protecting investors and ensuring the overall stability of the economy. By focusing on the financial institutions pillar within the EU and using the Glo­bal Competitiveness Index as a benchmark, this study can contribute valuable in­sights to policymakers and stakeholders, aiding them in making informed decisions to strengthen the EU’s financial sector and overall economic competiti­veness.
A 12-14 éves gyermekek pénzügyi személyiségének duális megközelítése egy négyéves vizsgálat alapján
Authors: Németh Erzsébet , Kálmán Botond Géza
Published: November 2023

Tanulmányunk célja olyan pénzügyi személyiségtipológia kialakítása, amely a gyerekek pénzügyi személyiségét a pénzügyi viselkedésformák, attitűdök, döntések alapján két csoportba sorolja. Saját kérdőívükkel mértük fel a 12–14 éves korosztályt Magyarországon. A felmérést online kérdőíves módszerrel végeztük, majd a kapott válaszokat statisztikai módszerekkel dolgoztuk fel. A gyerekek pénzügyi személyiségének összetevői összességében pozitív attitűdök. Vannak azonban kontroll nélküli költekezésre hajlamos, impulzív, vagy próba-szerencse alapon pénzügyi döntéseket hozó gyerekek is. A gyerekkori pénzügyi személyiség alakulását hat faktor határozza meg, melyek közül három előnyős, három pedig előnytelen. A negatív hatások erősebbek a pozitívaknál. A Takarékos és Cél­tudatos tervező faktorok magyarázottsága 10%, míg a jelentős negatív hatású Pénznyelő vonást a Kényeztető, a Követelő és az Önálló faktorok 68,2%-ban magyarázzák. Habár a mintánkban két csoportot különítettünk el, az útmodell mutatja, hogy a személyiségvonások komplex rendszert alkotnak. A negatív személyiségvonások jelentősen befolyásolják a gyerekkori pénzügyi döntéseket. Ezekre a gyerekekre a pénzügyi oktatás és nevelés programjainak kidolgozása során figyelmet kell fordítani.
EVOLUTION OF RUSSIAN NAVAL LEXICOGRAPHY: FROM MULTILINGUAL TO BILINGUAL DICTIONARIES
Authors:   Northern (Arctic) Federal University named after M. V. Lomonosov, Epimakhova Aleksandra S.
Published: November 2023

This paper presents an overview of naval dictionaries created in Russia in the 18th–20th centuries, with an emphasis on the number of languages involved and the thematic scope. The multilingual character of these dictionaries can be explained by a range of reasons. Some of them are created on the basis of existing foreign dictionaries translated into Russian; others are the result of interest to collecting linguistic facts in different languages; the authors can also be motivated by the lack of available lexicographic resources in minor languages. 20th century dictionaries are bilingual, with a narrower thematic specialization and focus on specific professional purposes. This development corresponds to the requirements for lexicographic resources and recommendations for lexicographers formulated by V. P. Berkov. These dictionaries are mostly English-Russian ones as English is historically associated with Russian marine science and it is also the language of international maritime communication.
POEMS ABOUT THE NORTH IN THE “SOUTHERN” LANGUAGE: THE EXPERIENCE OF TRANSLATING POEMS BY J. L. BORGES ABOUT ICELAND AND NORWAY
Authors:   St. Petersburg State University, Kovalev Boris V.
Published: November 2023

The article provides an analysis of the images of the Scandinavian countries constructed in the poetry of J. L. Borges. The individual essential characteristics of Norway and Iceland are revealed, which are used by Borges to build a holistic image. A number of cases that are difficult for a translator are analyzed and possible translation solutions are proposed. In the course of the study, it turns out that the image of Iceland is the most complex and significant for Borges: constructing it, the poet uses both general cultural and personal associations. The key constructive elements, functional categories of the image of Iceland are timelessness, cumulativeness (Iceland as a “hollow of memory”, a universal library), isolation and circularity. Each category manifests itself at different levels, repeating itself in different texts and thus forming a single Icelandic hypertext in Borges’ poetry.
ABOUT NON-IMPERATIVE FORMS OF MOTIVATION IN DANISH: VIL DU HJÆLPE MIG? — VIL DU IKKE HJÆLPE MIG?
Authors:   Lomonosov Moscow State University, Krylova Elvira B.
Published: November 2023

The article for the first time offers a comparative analysis of two non-imperative forms of motivation in Danish that have common structure and propositional content, but differ in the absence or presence of negation: Vil du (ikke) + Inf.? The author studies these interrogative expressions in various contextual situations to specify their motivational meanings, to explain ways to induce one of the alternative answers (ja/jо — nej) from an interlocutor, and also to suggest ways of translating them into Russian. It is shown that unlike the expression without negation Vil du hjælpe? the expression with negation Vil du ikke hjælpe? contains the speaker’s implied confidence that the listener will agree with the assessment of the described situation expressed in the statement component of the question and will provide the requested assistance. The expression without negation does not contain such inducement, which expands the scope of its usage in communication and makes it possible to use it as part of an alternative question.
MICROTOPONYMS AND PROPER NAMES IN TRANSLATIONS OF FICTION LITERATURE: TRANSLATION KILLERS OR CHANCE FOR EXPERIMENTS?
Authors:   Moscow State Linguistic University, Naumova Anastasia V.
Published: November 2023

The article discusses the problem of microtoponyms and some proper nouns when translating fiction works from the Norwegian to the Russian language. It is noted that commonly used transliteration, as well as transcription of microtoponyms, does not seem to be the most effective solution for the translated fiction text and might be affect readers’ perception of it. As a waiver of the rule, it is analysed a number of translation solutions in novel by contemporary Norwegian fiction writer Tomas Espedal Against Art. It is also brought up translation issues of proper nouns when the translation of the proper noun might be essential for text understanding, used with effect or is substantial for the plot. As an example of a successful translation solution, it is provided Russian translation of children’s graphic novel by Vilde Kamfjord On the detour home.
THE IMAGERY METAPHORS OF SPACE IN THE DUTCH WAR NON-FICTION WORKS
Authors:   Military University named after Prince Alexander Nevsky of the Ministry of Defense of Russian Federation, Stepanenko Evgenia A.
Published: November 2023

The article explores the roles space metaphors play in the Dutch war non-fiction novels published during the period of 2010–2020. We hereby define metaphor as instrument the authors use to make up a personal view and to portray the events described, as well as to introduce and to define a war metaphor as well as to study the functions metaphors can have within a non-fiction texts. Another point of the article is a phenomenon of war metaphor seen as complex cognitive units which principal function is to underline the subjects related to the World War II. War metaphors are present in the texts explicitly (x is y) but also implicitly, as images. Among the principal war metaphors in the texts are ‘war is lack of freedom’, ‘war is a a disclosed space’, ‘war is an up-and-down movement’. These metaphors are nationally marked and are transparent for the Dutch as nation. As the notion of space is deeply rooted in the Dutch culture, we suggest that the war is also presented in the Dutch non-fiction as lack of space and distortion of common living space.
(NON-)TRANSLATION OF MURALS POETRY IN THE NETHERLANDS: BACKGROUND AND REALISATION
Authors:   Institute of Linguistics, Russian Academy of Sciences, Tereshko Ekaterina V.
Published: November 2023

When you come to the Netherlands, you don’t expect to see poems in Russian, Chinese, Berber, or North American Indian on city walls. Even more surprising is the lack of translation or explanation of these texts. However, the (non)translation of murals in the Netherlands has a social background: at the same time when the poetry projects were most active, there was a heated discussion in the Netherlands about the possibility of creating a multicultural society. This idea dictated to the creators of the projects the image of a potential reader and obviated the need to translate poetry. In this article we will look at the ideas behind Dutch poetry projects, as well as the realization and functions of (un) translated murals. The collapse of the idea of a multicultural society has led to the need to translate poetry through various means, including modern online media. This allows us to speak of the intermediality of poetry and the mutual influence of the original text and the translation.
TRANSLATION OF THE NORWEGIAN SECOND PERSON SINGULAR PRONOUN DU INTO RUSSIAN
Authors:   St. Petersburg State University, Iakovleva Dariia V.
Published: November 2023

The article says about translation challenges related to the Norwegian second person singular pronoun du. The research aims to reveal translation alternatives that help to show pronoun usage characteristics in Russian and Norwegian. The point is that, apart from few exceptions, only pronoun du is used for address to one person in Norwegian nowadays, whereas Russian has two pronouns used in such a way. Based on theory and example analysis, translation guidelines have been presented. The general conclusion is that one might use either the pronoun ты, the pronoun вы, or the verb’s infinitive form instead of one of the pronouns, which depends on the situation considered and the text type, for it is important that the option should sound natural given the context.

Published: November 2023

Hydrological runoff prediction is vital for water resource management. The non-linear and non-stationary runoff series and the complex hydrological features for large-scale basins make it difficult to predict. Long short-term memory (LSTM) is effective for runoff prediction but unstable for large-scale basins. This study develops three hybrid models combined with two-stage decomposition and LSTM, including wavelet transformation (WT) combined with complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN), variational mode decomposition (VMD), and local mean decomposition (LMD), to predict the daily runoff of the Pearl River in China. The results indicate CEEMDAN's broader signal decomposition applicability for runoff series preprocessing, while VMD is simpler to extract high-runoff characteristics. VMD–WT–LSTM is appropriate for predicting high and median runoff, whereas CEEMDAN–WT–LSTM is better for low-runoff and high and median runoffs with low-violent fluctuations. These hybrid models provide satisfactory predictions for NSE and R2 indicators, and 97.2% of indicators fall within the acceptable range for high-runoff predictions. The hybrid models outperform traditional and standalone models in high-runoff but none of the decomposition methods in this research can identify low-runoff sub-sequence. This study provided runoff prediction methods requiring fewer data and processing time, and these methods are promising alternatives for daily runoff prediction in large-scale basins.

Published: November 2023

Industrial textile wastewater contains high levels of dyes, which are potentially harmful to aquatic ecosystems by inhibiting sunlight penetration for photosynthesis activities. Adsorption is a simple method for pollutant removal for water treatment. Magnetic Chitosan Microspheres (MCM) has been developed as a natural adsorbent for dye removal. This study aimed to compare the properties of the raw adsorbent and after adsorption by FT-IR, BET, DLS, and SQUID Magnetometry. The adsorption behaviours were investigated by the influence of pH, contact time, and initial concentration on Methyl Orange removal. The result was MCM could eliminate MO until 93.60% at pH 7 with C0 100 mg L−1 in 5 min with an adsorption capacity of 187.21 mg g−1. Adsorption processes were also studied through the isotherm and kinetic. The isotherm showed a closer fit to the Langmuir model than the Freundlich model. The kinetic result showed the PSO model was more suitable than PFO. The research data using MCM for adsorption demonstrated excellent adsorption capability in terms of dye removal percentage and high adsorption capacity. Therefore, this material could be an effective adsorbent for the treatment of dye-containing wastewater.

Published: November 2023

Objective. To evaluate the influence of lutropin alfa (recombinant human LH, r-hLH) administered at 12 and 24 h post-progesterone device removal (CIDR) on the response of hours to the onset of estrus, ovulatory rate, unfertilized oocytes, transferable embryos and plasmatic levels of LH, in a multiple ovulation protocol based on FSHp in Pelibuey sheep. Materials and methods. Eighteen sheep of Pelibuey sheep were used, which were randomly distributed into three treatments (n=6): T1 (200 mg FSHp-Folltropin®); T2 (200 mg pFSH + 75 IU r-hLH at 12 h post-CIDR withdrawal) and T3 (200 mg pFSH + 75 IU r-hLH at 24 h post-CIDR withdrawal). Results. Hours from start to estrus and ovulatory rate (OR) no significant differences were found. In unfertilized oocytes (UO) it was higher (p<0.05) in T2 (5.0 ± 2.3) compared to T1 (0.8 ± 0.6) and T3 (1.3 ± 0.7). The number of Quality 1 Embryos (Q1E) was higher (p<0.05) in T3 (3.1 ± 1.1) compared to T1 (1.1 ± 0.3) and T2 (0.6 ± 0.5) and for Transferable Embryos (TE) it was higher (p< 0.05) for T3 (6.6 ± 0.9) in relation to T2 (2.0 ± 1) and T1 (4.0 ± 0.6). Conclusions. The application of r-hLH 24 h after removing the CIDR increases plasma levels of LH, in effect, the number of unfertilized oocytes is reduced, and the number and quality of transferable embryos in Pelibuey sheep are improved.

Published: November 2023

Objective. To estimate the heritability (h2) of age at first parturition (AFP), longevity (L), useful life (UL), and productivity (P), as well as the genetic (rg) and phenotypic correlations between those traits in Brown Swiss and Holstein cows in Northwestern Honduras. Materials and methods. Cattle were raised under tropical conditions and intensive management. The model for AFP assessed the effect of contemporary group (herd, year and birth season combination) as fixed. The model used for L, UL and P included the contemporary group, age group at first calving and their interaction. Data were analyzed using restricted maximum likelihood procedure, adjusted to a univariate and to a bivariate animal model. Results. The h2 estimated for AFP, L, UL and P were 0.16, 0.18, 0.25 and 0.09, respectively, in Brown Swiss cows, and 0.53, 0.49, 0.7 and 0.22, respectively in Holstein. Negative but favorable rg among Brown Swiss cow traits ranged from 0.31 to 0.46 between AFP and the other traits. However, for Holsteins cows, positive rg among AFP and the other traits here studied varied from 0.49 to 0.96. In both cattle breeds, rg among L, UL and P, traits were positive. Conclusions. For all traits evaluated low to medium heritability’s for BS suggest that a slow genetic improvement could be achieved if independent selection of traits is applied, and better response could be expected for H breed. For both breeds the positive rg among L, UL and P suggest thar similar selection criteria could be used.

Published: November 2023

Objective. To evaluate pre-weaning growth traits of Angus-, Brahman- and Wagyu-sired calves. Materials and methods. One-hundred seventy one calves were produced by artificial insemination in nine herds in the state of Puebla (subtropical environment; n=83) and four herds in the state of Veracruz (tropical environment; n=88), Mexico. Eleven Angus, 15 Brahman, and 5 Wagyu bulls, sired the calves. Average age at weaning was 219 days. The analyses were carried out with the MIXED procedure of SAS. The model included the effects of breed of sire, sex of calf, birth season, state of the country, and herd nested within state. In addition, the model for actual weaning weight included the linear effect of calf age at weaning. Results. Brahman-sired calves were heavier at birth (p<0.05) than Angus- and Wagyu-sired calves; however, Angus-, Brahman- and Wagyu-sired calves had similar average daily gains from birth to weaning (p>0.05). Angus- and Wagyu-sired calves had similar actual weaning weights (p>0.05), but Brahman-sired calves were heavier at weaning (p<0.05) than Wagyu-sired calves. Sex of calf and season of birth were not significant sources of variation (p>0.05) for any trait. Calves reared in subtropical conditions were heavier at weaning (p<0.05) than those reared in tropical conditions. Conclusions. In general, Brahman-sired calves had a better pre-weaning performance than Angus- and Wagyu-sired calves.

Published: November 2023

Background

CKD has been implicated as a risk factor of venous thromboembolism, but the evidence is limited to relatively healthy populations. The objective of this study was to discern whether parameters of kidney function and damage are associated with the occurrence of venous thromboembolism after hospitalization.

Methods

We conducted a retrospective study including 23,899 and 11,552 adult individuals hospitalized within Geisinger Health System and New York University (NYU) Langone Health from 2004 to 2019 and 2012 to 2022, respectively. A Poisson model was used to evaluate adjusted incidence rates of venous thromboembolism according to eGFR and albuminuria categories in each cohort. Cox proportional hazards models were used to analyze associations of eGFR and urinary albumin-to-creatinine ratio (UACR) with venous thromboembolism, and hazard ratios (HRs) were meta-analyzed across cohorts.

Results

Both lower eGFR and higher UACR were associated with higher risks of venous thromboembolism. In the Geisinger cohort, the incidence of venous thromboembolism after hospital discharge ranged from 10.7 (95% confidence interval [CI], 9.2 to 12.6) events per 1000 person-years in individuals in G1A1 (eGFR >90 ml/min per 1.73 m2 and UACR <30 mg/g) to 27.7 (95% CI, 20.6 to 37.2) events per 1000 person-years in individuals with G4-5A3 (eGFR <30 ml/min per 1.73 m2 and UACR >300 mg/g). A similar pattern was observed in the NYU cohort. Meta-analyses of the two cohorts showed that every 10 ml/min per 1.73 m2 reduction in eGFR below 60 ml/min per 1.73 m2 was associated with a 6% higher risk of venous thromboembolism (HR 1.06 [95% CI, 1.02 to 1.11], P = 0.01), and each two-fold higher UACR was associated with a 5% higher risk of venous thromboembolism (HR 1.05 [95% CI, 1.03 to 1.07], P < 0.001).

Conclusions

Both eGFR and UACR were independently associated with higher risk of venous thromboembolism after hospitalization. The incidence rate was higher with greater severity of CKD.

Authors: Wan Lu , Zhou Xi , Qiu Weiyao
Published: November 2023

In order to understand the effect of COVID-19 on the mental health status of college students, The Symptomatological Check List-90 (SCL-90) was used to conduct 2 psychological tests on 537 college students enrolled in a college at the 8th and 20th month after the naming of COVID-19. The results of the study showed that: 1) 1st psychological test: 98 students (18.25%) had abnormal total scores (GSI≥160) and 35 students (6.5%) had GSI ≥200; 119 students (22.16%) had abnormal number of positive items (≥43). 2nd test: 66 (12.29%) students with abnormal total score (GSI ≥160), 18 (3.35%) students with GSI ≥200; 77 (14.34%) students with abnormal number of positive items (≥43). (ii) The number of students with factor scores ≥2 on the 2nd test decreased from the 1st, with the factor with the largest decrease in scores being anxiety, with a decrease ratio of 48.53%. The order was psychoticism 45.71%, paranoia 41.03%, terror 37.10%, depression 35.44%, and compulsion 34.36%. (iii) Levene's test, independent samples t-test and comparison of means were performed on the scores of boys and girls on the 10 factors in the 1st test, and there was no statistically significant difference in all factor scores. (iv) Independent samples t-test was conducted on the 1st test for only children and non-only children, and there was a statistically significant difference in the 3 factors of obsessive-compulsive symptoms, interpersonal sensitivity, and depressive symptoms, and the scores of non-only children were higher than those of only children.
Communicative Competence in Spiral Progression Curriculum: A Study Reinforcing the Implementation of MATATAG Curriculum in the Philippines
Authors: P. Alvarado Carl Christopher
Published: November 2023

The Philippine English curriculum aims to produce communicatively competent individuals, considering that Filipinos are known to be proficient in the use of the English language. However, there has been a poor performance of Filipino learners in international assessments, and their English proficiency has been declining over the recent years. The English curriculum in the Philippines plays a crucial role in the development of communicative competence of students. One of its principles that is said to be disjointed and is presumed to have affected the communicative competence of students is the spiral progression approach. Accordingly, this research aims to identify and to interpret the teachers’ implementation of the spiral progression approach in junior high school English in selected public schools in the second district of Ilocos Sur that could have influenced the communicative competence of students that prompted the Department of Education to revise the current Philippine curriculum. Findings revealed that teachers implemented the said approach. This was later substantiated through a documentary analysis and a semi-structured interview with the school managers. However, findings also revealed that there is an inconsistency in its implementation that can be linked to the poor performance of Filipino learners in international assessments. From these findings, it was concluded that teachers shall equip themselves with strategies and techniques through a series of training, and the reduction of learning competencies can address the broken continuity to ensure mastery. Hence, curriculum change is supported.

Stakeholder participation is crucial for the success and well-being of any organization. The study aimed to explore challenges facing stakeholder’s participation in improving teaching and learning process in public secondary schools. The study employed an explanatory sequential mixed method design under a mixed research approach where the information was collected through questionnaires, interview guides and documentary reviews. The sample size of this study was 195, and simple random sampling, stratified sampling and purposive sampling techniques were applied to choose the respondents. Quantitative data were analyzed through SPSS version 20, while qualitative information was analyzed thematically. Again, the results of the study show that political interference, lack of awareness, poverty, negligence of some parents, lack of transparency and poor relationships with parents were the major challenges identified to affect stakeholders in supporting teaching and learning process. The study recommended that parents and other stakeholders should be enlightened about their duties and responsibilities in education to enhance their participation in supporting education issues. Additionally, a government should prepare a good policy that clearly states parents’ roles and duties in education to be aware of what they are required to contribute to supporting students’ learning.

This study evaluated the impact of chilling decline rates on carcass and meat quality parameters of Bos indicus cattle. Eighty Nellore bull carcass halves were used, allocated equally into 2 treatments: conventional and dynamic chilling environment. Temperature and pH were recorded at 0, 2, 4, 6, 12, and 24 h in the longissimus thoracis muscle. Cold carcass weight and meat samples were extracted 24 h post-slaughter. Cold carcass weight tended to be lower in the dynamic environment (P=0.096). Shrink percentage was higher in the conventional than in the dynamic chilling environment (P=0.049). The pH values were significantly higher in the dynamic chilling environment at 2, 4, 6, and 12 h after slaughter (P<0.022). Also, there was a tendency for high ultimate pH in the dynamic treatment (P=0.059). Temperature values were significantly lower in the dynamic treatment from 4 to 24 h postmortem (P<0.001) compared with the conventional treatment. Carcasses subjected to the conventional chilling rate presented higher temperatures at pH 6 (P<0.001), which was reached in a shorter period (P=0.024). Carcasses in the conventional treatment had a lower pH at the temperature of18°C than in the dynamic chilling environment (P<0.001). There were no differences in water losses and sarcomere length between chilling environments (P≥0.344). However, meat samples from the conventional chilling environment had higher mean values for color parameters a*, b*, oxymyoglobin, and chroma (P≤0.006) and a tendency for lower shear force (P=0.06). In contrast, the deoxymyoglobin value was higher in the dynamic than the conventional chilling treatment (P=0.002). The variation in chilling rate impacted mainly the decline in meat pH and meat color, with the dynamic chilling environment producing a less bright red color.

Published: November 2023

Актуальной научной проблемой в сетях связи пятого и последующих поколений является эффективная организация одновременной работы совокупности направленных радиолиний при сверхплотном распределении устройств. Одним из решений является концепция диаграммообразования на основе позиционирования LAB (Location Aware Beamforming). Настоящее исследование посвящено описанию модели двух радиолиний, в которых управление диаграммой направленности антенны на стационарных базовых станциях выполняется на основе текущего местоположения подвижных пользовательских устройств. Результаты имитационного моделирования показывают, что при реализации концепции LAB необходимо учитывать как территориальный, так и угловой разнос пользовательских устройств.

supervisión de acuerdos de soluciones amistosas entre las comisiones regionales de derechos humanos
Authors: Hernández Barrera Yeshu
Published: November 2023

El acceso a la justicia pronta no es efectivo en los mecanismos internacionales de protección de derechos humanos. La admisión de una petición individual ante la Comisión Interamericana y de la Comisión Africana de Derechos Humanos y de los Pueblos tarda entre uno y seis años y para obtener un informe de fondo pueden transcurrir cuatro años más. En caso de que los asuntos lleguen y la Corte Interamericana o a la Corte Africana de Derechos Humanos y de los Pueblos emitan una sentencia, habrá transcurrido una década. Para reducir los tiempos procesales, el Consejo de Europa eliminó a la Comisión Europea de Derechos Humanos, permitiendo el acceso directo a su Tribunal. No obstante, en América y África esto no es conveniente, pues en el caso europeo, todos los Estados están sometidos a la jurisdicción de su Tribunal.
