The paradox of independent board members and financial return of state-owned enterprises: Case of Lithuania
Authors: Voveris Donatas , Jaržemskis Andrius , Girdvainienė Ieva
Published: January 2024

The relationship between governance measures and company performance is a widely debated topic in economics, finance, and organizational analyses with diverse outcomes in the existing scholarly body of work. This study aims to examine the relationship between the share of independent members on the board and the financial return of state-owned enterprises. Lithuania was chosen as a setting for the research because the country has been successfully implementing ambitious corporate governance reforms in the public sector and thus is recognized by the Organisation for Economic Co-operation and Development for its efforts. Within the examined dataset of 27 Lithuanian state-owned enterprises spanning 2015 to 2021, there was a notable rise in the proportion of independent board members, ascending from 13% in 2015 to 61% in 2021. However, no statistically significant correlation is discerned between the share of independent board members and financial performance indicators, specifically return on assets (r (181) = –0.020, p > 0.05) and return on equity (r (181) = –0.104, p > 0.05). The quantitative results are complemented through the administration of semi-structured interviews with a subset of board members affiliated with these enterprises. The absence of a relationship between independent board members and the financial return is explained via a more significant influence of state decisions than the effect of a board. Therefore, the appointment of independent board members alone cannot be regarded as the sole guarantor of improvement in financial returns.

The increase in the number of users, hospitalizations and deaths due to overdose of synthetic opioids made the scientific community to treat this problem as “the opioid crisis”, justifying the need for the development of analytical strategies to identify and quantify these drugs. Even with the global discussion, there is no Brazilian data regarding opioids consumption, addiction or fatal intoxication cases. The aim of this work was to develop, validate and applied an analytical method based on liquid chromatography-tandem mass spectrometry for determination of fentanyl and seven analogues (acetyl norfentanyl, acetyl fentanyl, thiofentanyl, acrylfentanyl, furanylfentanyl, carfentanil and valerylfentanyl) in postmortem blood samples, to the routine analysis of the Forensic Toxicology Laboratory of São Paulo State Police. Linearity was evaluated from 1-500 ng mL-1 (correlation coefficient (r) value (r ≥ 0.99), 1/x weight linear regression), with limit of quantification of 1 ng mL-1. The method imprecision, bias and matrix effect were lower than 19.7%. No interference or carryover were observed, and extraction yield was greater than 57.7%. Analysis of postmortem blood samples (n = 1,359) showed that fentanyl was the most frequently detected opioid. The developed method proved to be useful for routine analysis of the Forensic Toxicology Laboratory.
Assessing the spatial variation of water poverty determinants in Maharashtra, India
Authors: Dhawan Aishwarya , Gundimeda Haripriya
Published: January 2024

Water scarcity is an emerging multidimensional issue concerning not only the physical availability of resources but also is linked with poverty. The existing literature has established a relationship between income poverty and water poverty. In the Indian context, various studies have explored such issues using the Water Poverty Index (WPI), but only a few have analyzed downscale spatial units. This paper constructs district-level water poverty measures and maps its spatial heterogeneity for Maharashtra, India. Using an indicator-based approach, we aggregate various dimensions of water poverty into a single index. This composite index is formulated by normalizing the indicators and assigning weights using principal component analysis. After rescaling, the aggregate WPI score varies from 0 to 1, denoting lower to higher water poverty. The overall WPI estimate of Maharashtra is 0.47, implying high water stress. The study presents district-wise WPI information by combining the results with Geographic Information System (GIS). Our findings suggest that along with the physical abundance and accessibility to water, improvement in the determinants of capacity and environment is essential to tackle water poverty. Results highlight the intra-district variations among components of water poverty, indicating the importance of local-scale policy-making for better water resource management.
Microdistrict as an element of a city’s visual representation the Tyumen region
Authors: Bubnov Dmitry O.
Published: January 2024

This article studies the formation of the visual image of the late Soviet city in 1960s – early 1990s in Western Siberia, approaches to representation and some of its elements. The author aims to show the process of formation of the visual representation of the Western Siberian city of the late Soviet period during the industrial development. The object of the study is an image of the microdistrict as a central element of urban space in late Soviet era. These cities actively developed during the development of the West Siberian oil and gas complex, which allowed to turn these cities into an experimental platform for bold everyday life solutions. This defined new approaches to the visual representation of the late-Soviet city, where the focus was not only on squares, factories and “advanced socialist districts”, like the 1930s. These changes can be traced to the emergence of new elements of the visual image of the city. One of such elements of the visual image of the late Soviet West Siberian city was a microdistrict that appeared during the transition to standardized housing construction that began in the 1950s. It was a “city in miniature” with its own social infrastructure, streets, but it was still reflecting the old idea of a “collective community of Soviet society” in general. These factors predetermined the specificity of the visual image of the late Soviet city, which was an industrial, economic, scientific and cultural center.
The functions of literary allusions in Old Possum’s Book of Practical Cats by T. S. Eliot
Authors: Marshaniya Kristina M.
Published: January 2024

This article deals with the functions of literary allusions in Old Possum’s Book of Practical Cats by T. S. Eliot. The material of the study is the book of verses included into the annotated anthology The Poems of T. S. Eliot. Vol. 2. Practical Cats and Further Verses (2015) compiled and edited by the leading contemporary Eliot scholars, British-American researcher Sir Christopher Ricks and renowned British critic and publisher Jim McCue. In this paper, the author considers different types of allusions in T. S. Eliot’s poems and determine their specificity. This has required using cultural historical approach and methods of literary structural analyses. The purpose of the study is to confirm that the intertextuality of Old Possum’s Book of Practical Cats is represented by a new type of allusiveness, which is an important element of modernist aesthetics. Intertextuality in T. S. Eliot’s book of verses is a complex system of connections between texts and phenomena of various cultural and historical layers. Allusions change the status of the texts of the book, make them heterogeneous and help to expand their figurative structure. A characteristic feature of Eliot’s modernist allusion is its multi-composition where one and the same image can be correlated to various literary texts and cultural eras. The intertextuality of Old Possum’s Book of Practical Cats proves that these verses were addressed for an adult audience as well, since only an intellectually “savvy” reader familiar with a wide range of literature and art works, various cultural traditions and historical eras is able to understand the different textual levels and the artistic intentions of the poet.
Edward Hopper and Ernest Hemingway: Problem of Creative Connections
Authors: Meister German
Published: January 2024

This paper focuses on revealing connections between the creative work of two representatives of the US realism of the early 20th c.: the painter Edward Hopper (1882–1967) and the literary artist Ernest Hemingway (1899–1961). This problem has received studied, only if superficially. Yet Hopper and Hemingway were “key” personalities of the epoch which built them: both of the artists were expatriates, absorbed experience of “European” aesthetic trends, witnessed two world wars; that led to the existentialism concepts becoming central ideas in their creative work. Being self-made men, Hopper and Hemingway went through a similar path of personal growth, were recognized in the 1920s when their artistic style developed; the artists were devoted to it despite domination of different movements in art. Regardless of difference between the artists’ “temperament”, the form of their works is mostly similar in the application of realistic method, influence of impressionist and modernist trends, the desire for simplicity, as well as the focus on light and darkness. The pictorial and thematic affinity of Hopper's and Hemingway's several works is so great that a direct mutual influence between the artists seems very likely.

Authors: Kustova Galina I.
Published: January 2024

This paper presents a study on nominalized adjectives and participles denoting a person. It distinguishes between occasional nominalizations, usual nominalizations (chuzhoi ‘alien’, postoronnii ‘outsider’, mestnyi ‘local’, prisutstvuyushchii ‘present’, zhelayushchii ‘willing’, otdykhayushchii ‘resting’) , and dictionary nominalizations (veruyushchii ‘believer’, voennyi ‘military’, podchinennyi ‘subordinate’, sluzhashchii ‘employee’). The paper discusses the specific usage of adjectives and participles from the usual group in constructions with the pronouns nikto ‘nobody’, kto-to ‘someone’, kto-nibud’ ‘anyone’: kto-to neznakomyi ‘someone unfamiliar’. Additionally, it examines the variability of number forms, for example nikogo znakomogo — nikogo znakomykh (no one familiar sg. — no one familiar pl.). The article is based on a paper presented at the 7th International Research Symposium “Russian Grammar: Constants, Contexts, Perspectives” (October 10–14, 2023, Tyumen).
Introduction of 19th century manuscripts from local historians of the Tobolsk Province into scholarly research
Authors: Bagirova Elena P.
Published: January 2024

This article evaluates a monograph written by linguist O. V. Trofimova and historians N. I. Zagorodniuk and E. N. Konovalova. The monograph is the first in a series of scientific publications that analyze manuscripts from the Scientific Archive of the Russian Geographical Society (RGS) regarding Tobolsk Province in the second half of the 19th century. The focus of the first book in the series is on the language used by the Russian population of Tobolsk Province. The linguistic materials were collected by Siberian local historians N. A. Abramov, V. V. Adrianov, I. V. Bednyakov, F. K. Zobnin, M. I. Kostya, I. F. Lisitsyn, V. F. Tveritin, and A. G. Khudyakov at the request of the Ethnographic Program of the RGS. The publication begins with a historical overview of the Russian Geographical Society and its programs, as well as biographies of the local historians who collected the linguistic materials. The main focus of the monograph is on “Materials for the dictionary of Russian folk speech of Tobolsk province of the 19th century (1848-1891)”. These materials, derived from eight author’s dictionaries, provide insight into the unique characteristics of Russian speech in various locations in Western Siberia. The significance of this research lies in the need to incorporate new linguistic materials into scientific discourse, as they are valuable for understanding the history of language. The novelty of this work lies in its contribution to historical and lexicographic studies, which are relatively scarce in Russian historical research, as well as its exploration of the local peculiarities of the Russian language in Western Siberia during the 19th century. The information presented in this monograph makes a substantial contribution to preserving and describing Siberian written texts. It also aids in the study of dialectal differentiation of the Russian language, particularly in the realm of secondary colloquialisms and in specific territories of Western Siberia. Additionally, it helps reconstruct a comprehensive understanding of the vocabulary used during the latter half of the 19th century.
Influence of noisy input data in accuracy of well interference coefficients by linear regression method
Authors: Ganopolskij Rodion M.
Published: January 2024

Hydrodynamic simulators are used to predict the operation of a production well. Their work demands high performance. Alternative simplified methods are appearing constantly, for example, proxy models. Firstly, these models are tuned to historical data and then they make predictions. The source data is quite inaccurate and incomplete often. It is necessary to study how an input parameter error affects quality of forecast.
This article shows an algorithm for determining the well interference coefficients by linear regression method. Study was made of the stability of the obtained solution to the noise of the initial data under various conditions. A production well forecast has been obtained, which is then compared with the exact value. The error in which initial data has the greatest impact on the forecast error is analyzed. Possible options for ensuring sustainability are proposed.
Composite structure of the magnesium ball valve element for a drilling well
Authors: Loginov Yuriy N. , Zamaraeva Yuliya V.
Published: January 2024

In the oil industry, balls are used in the process of hydraulic fracturing (HF). The material that meets the basic requirements for HF balls is magnesium. Soluble magnesium balls are designed to activate HF couplings. When the coupling seat is reached, during the pumping of HF fluid, the ball temporarily blocks the passage section inside the shank column, which makes it possible to create excess pressure and open the windows of the HF coupling. However, since magnesium has a low density, in drilling fluids with a high density, leaky contact of the ball with the valve seat is possible due to insufficient gravity. This may lead to leakage of the working fluid. The purpose of the work is to create and study a method of manufacturing a ball aimed at weighing it down.
The developed method of manufacturing a two-layer ball valve element by stamping is described. The two-layer ball consists of a magnesium shell, inside which a steel ball is placed. A steel ball is placed in a magnesium cylindrical glass with a bottom, the glass is closed with a magnesium lid. The resulting composite assembly is deformed by being compressed with two punches with ends in the form of hemispheres until the ends of the cylindrical cup are tightly closed. As a variant, the shell of the ball is proposed to be made of Mg90 grade magnesium. It is theoretically established that the mass of a bimetallic ball is 2.74 times larger than a magnesium ball. Modeling of stamping of a composite billet is performed in order to establish the possibility of obtaining a ball according to the proposed method. The stress-strain state of a composite billet in the process of shaping is considered. Successful computer simulation of the process gives grounds to recommend the proposed method for implementation in a real experiment. The smallest value of the ratio of the cylinder wall thickness to its height is also established, which ensures the stability of the cylinder wall during deformation.
Modeling the spread of an infectious disease with fly-in-fly-out work method
Authors: Podzolkov Pavel N. , Zakharova Irina G.
Published: January 2024

The article discusses problems related to building models for the spread of infectious diseases. It explores the relevance of epidemiological modeling in various public spheres, including how production processes can impact disease spread. The article analyzes the possibilities of using compartmental epidemiological models for epidemiological modeling, taking into account population migration and geography. It also considers methods for constructing compartmental models that account for mortality due to the disease. The article proposes an approach to constructing compartmental models that considers population heterogeneity, dividing it into non-overlapping subsets based on contact intensity indicators. Additionally, the article describes a method for modeling migrating subsets within this approach.
The article demonstrates the results of constructed epidemiological models for the spread of infection between localities, taking into account migration fly-in-fly-out worker groups. It compares models with different interactions between individuals of subsets and shows that the order of infection spread between subsets affects epidemic dynamics but not the total number of affected individuals. The article also demonstrates that direct contact can accelerate epidemic transmission between subsets compared to transmission through migrating groups.
The proposed approach can be used to implement an epidemic simulation system that accounts for migration, geographical factors, and the nature of participant interaction in the production process.
Simulation of liquid production and water cut dynamics using fluid flow model and neural networks
Authors: Legostaev Dmitry Yu. , Kosyakov Vitaly P.
Published: January 2024

In the oil industry, there is a noticeable tendency to use proxy modeling of various levels of complexity to perform operational predictive calculations, in particular machine learning methods that are actively developing in the context of digitalization and intellectualization of production processes. In this paper, using the example of a synthetic oil reservoir model development element, we present an approach to the joint use of a physically meaningful fluid flow model and machine learning methods for solving adaptation and prediction problems. A feature of the considered synthetic model is the presence of a pronounced zonal inhomogeneity of the permeability field. Within the framework of the proposed approach, a single-phase filtration model, simplified in comparison with the original formulation was used, the history matching of which was carried out by restoring the field of reservoir filtration parameters using a network of radial basis functions. Based on the reconstructed field, the connection coefficients between the wells were calculated, which qualitatively and quantitatively correspond to the true well connections. The next step was to train a recurrent neural network in order to predict the water cut of the produced fluid. The use of a recurrent neural network made it possible to reproduce the characteristic non-monotonic behavior of the water cut of the produced fluid, caused by non-stationary modes of operation of injection and production wells. A combination of the presented models makes it possible to predict the volume of the produced fluid and its phase composition. To assess the predictive properties of the models, the actual data set was divided into training and test intervals.

Published: January 2024

The article discusses ways to increase the efficiency of condensate production due to the optimal distribution of gas flows between producing wells. For a large number of wells, the solution of this problem becomes nontrivial and requires special methods of nonlinear optimization. The main aim of research is obtaining accurate solutions to the problem of optimizing condensate production using direct dependencies between gas and condensate production. The minimum set of reliable field information has been determined, which allows solving the problem of optimal distribution of gas production between wells at the maximum condensate flow rate. An optimization problem is formulated for this model. The conditions under which the initial problem is divided into a system of optimization subtasks for subgroups of wells are considered. By the method of pairwise optimization, analytical expressions were found for optimal ratios of gas flow rates in a group of wells. Based on the expressions obtained, an algorithm has been developed for the exact solution of the problem of short-term optimization of the well operation mode.

Published: January 2024

Pumping water into productive formations is one of the most common methods of oil field development. The effectiveness of reservoir flooding technology largely depends on the compliance of the design and actual volumes of water injection. Due to the violation of the tightness of the cement ring, fluid flows occur in the column space, which cause non-project withdrawal of the injected liquid into non-perforated layers. Identification and prompt elimination of backwater flows during injection of liquid into injection wells is one of the important tasks of efficient and environmentally friendly development of oil fields.
The paper considers the use of induction heating of the casing string to determine the bottom-up backflow when pumping liquid into the well. The research is based on numerical modeling in the Ansys Fluent engineering package. Scenarios of absence and presence of overflow during injection of liquid into the well are simulated. It is shown that in a well without overflow, the temperature field disturbance propagates from the heated section of the column mainly radially into cement and rocks, in a well with overflow, the thermal disturbance from the heating section also propagates vertically in the direction of the overflow, and at a distance of up to 1 m above the heating section, temperature disturbances in the column body and the column space reach 2…3 K. It was found that the signs of overflow are also a decrease in the degree of heating of the casing string and an increased dynamics of cooling of the column over time compared with the absence of the column movement of the liquid. The results obtained serve as a theoretical justification for the fundamental informativeness of the active thermometry method in the diagnosis of backwater flows in injection wells.
Investigation of the temperature distribution in a heterogeneous reservoir during fluid filtration, taking into account thermodynamic effects
Authors: Suleimanova Malika D. , Sharafutdinov Ramil F. , Kanafin Ildar V.
Published: January 2024

The purpose of the work is to study the temperature field in a formation with heterogeneous permeability during non-stationary non-isothermal two-phase filtration of oil and water, taking into account Joule–Thomson and adiabatic effects. The novelty of the study lies in the establishment of patterns of temperature distribution during two-phase filtration in a formation with heterogeneous permeability, non-monotonic temperature changes associated with two-phase filtration.
Numerical experiments have shown that during non-stationary two-phase non-isothermal filtration of water and oil in the bottomhole region of the formation in its heterogeneous zone, temperature formation occurs at different rates in the angular distribution at the initial moments of well operation. In this case, depending on the ratio of the permeabilities of the formation and the heterogeneity zone and on the initial water saturation of the formation, during two-phase filtration in the heterogeneity region relative to the homogeneous one, either a decrease in temperature or, vice versa, an increase in temperature can be observed.
The results obtained can be used when interpreting temperature measurement data using multi-sensor borehole equipment in formations with heterogeneous permeability in the presence of multiphase flows, and solving problems of the ecology of freshwater horizons.
The Foundation, The Network and the Climate Community come together to locate Climate Action in Europeana
Authors: Hazan Susan
Published: January 2024

This paper focuses on the implications of digital museum holdings and how cultural heritage institutions are managing their digital content and transactions while facing the climate emergency. The effects of climate change are already impacting cultural heritage in many ways, threatening our heritage landmarks, buildings, and collections. Inspired by New European Bauhaus (NEB), we are motivated to create cultural practices that can help our sector translate the Bauhaus vision into innovative and transformational urban-regeneration and efficient green-transformative processes including digital initiatives and practices. Only when we acknowledge that climate change is an emergency and make the sectoral decision take joint action will we be able to reverse this momentum and work towards a greener future. Speaking from the perspective of Europeana as an Initiative that represents over 4,000 museums libraries and archives across Europe, this paper discusses how Europeana works towards both a digital AND a green future. It is not enough simply to praise our paperless office, our digital collections systems, and electronic communications. We need to turn our attention to think about both the short- and long-term impact of our digital practice and, as soon as possible, learn to make the right choices. We turn for inspiration here to the NEB initiative directed by the European Commission to think green, sustainable and affordable, alongside accessible, inclusive, and beautiful and impacting all aspects of how we live.
Use of Large Language Models to Assess the Likelihood of Epidemics From the Content of Tweets: Infodemiology Study
Authors: Deiner Michael S , Deiner Natalie A , Hristidis Vagelis , McLeod Stephen D , Doan Thuy , Lietman Thomas M , Porco Travis C
Published: January 2024

Background

Previous work suggests that Google searches could be useful in identifying conjunctivitis epidemics. Content-based assessment of social media content may provide additional value in serving as early indicators of conjunctivitis and other systemic infectious diseases.

Objective

We investigated whether large language models, specifically GPT-3.5 and GPT-4 (OpenAI), can provide probabilistic assessments of whether social media posts about conjunctivitis could indicate a regional outbreak.

Methods

A total of 12,194 conjunctivitis-related tweets were obtained using a targeted Boolean search in multiple languages from India, Guam (United States), Martinique (France), the Philippines, American Samoa (United States), Fiji, Costa Rica, Haiti, and the Bahamas, covering the time frame from January 1, 2012, to March 13, 2023. By providing these tweets via prompts to GPT-3.5 and GPT-4, we obtained probabilistic assessments that were validated by 2 human raters. We then calculated Pearson correlations of these time series with tweet volume and the occurrence of known outbreaks in these 9 locations, with time series bootstrap used to compute CIs.

Results

Probabilistic assessments derived from GPT-3.5 showed correlations of 0.60 (95% CI 0.47-0.70) and 0.53 (95% CI 0.40-0.65) with the 2 human raters, with higher results for GPT-4. The weekly averages of GPT-3.5 probabilities showed substantial correlations with weekly tweet volume for 44% (4/9) of the countries, with correlations ranging from 0.10 (95% CI 0.0-0.29) to 0.53 (95% CI 0.39-0.89), with larger correlations for GPT-4. More modest correlations were found for correlation with known epidemics, with substantial correlation only in American Samoa (0.40, 95% CI 0.16-0.81).

Conclusions

These findings suggest that GPT prompting can efficiently assess the content of social media posts and indicate possible disease outbreaks to a degree of accuracy comparable to that of humans. Furthermore, we found that automated content analysis of tweets is related to tweet volume for conjunctivitis-related posts in some locations and to the occurrence of actual epidemics. Future work may improve the sensitivity and specificity of these methods for disease outbreak detection.
mHealth App Usability Questionnaire for Stand-Alone mHealth Apps Used by Health Care Providers: Canadian French Translation, Cross-Cultural Adaptation, and Validation (Part 1)
Authors: Gagnon Julie , Probst Sebastian , Chartrand Julie , Lalonde Michelle
Published: January 2024

Background

An increasing number of health care professionals are using mobile apps. The mHealth App Usability Questionnaire (MAUQ) was designed to evaluate the usability of mobile health apps by patients and providers. However, this questionnaire is not available in French.

Objective

This study aims to translate (from English to Canadian French), cross-culturally adapt, and initiate the validation of the original version of MAUQ for stand-alone mobile health apps used by French-speaking health care providers.

Methods

A cross-cultural research study using a well-established method was conducted to translate MAUQ to Canadian French by certified translators and subsequently review it with a translation committee. It was then back translated to English. The back translations were compared with the original by the members of the committee to reach consensus regarding the prefinal version. A pilot test of the prefinal version was conducted with a sample of 49 potential users and 10 experts for content validation.

Results

The statements are considered clear, with interrater agreement of 99.14% among potential users and 90% among experts. Of 21 statements, 5 (24%) did not exceed the 80% interrater agreement of the experts regarding clarity. Following the revisions, interrater agreement exceeded 80%. The content validity index of the items varied from 0.90 to 1, and the overall content validity index was 0.981. Individual Fleiss multirater κ of each item was between 0.89 and 1, showing excellent agreement and increasing confidence in the questionnaire’s content validity.

Conclusions

This process of translation and cultural adaptation produced a new version of MAUQ that was validated for later use among the Canadian French–speaking population. An upcoming separate study will investigate the psychometric properties of the adapted questionnaire.

Published: January 2024

BACKGROUND

Adolescents often experience a heightened incidence of depressive symptoms that can persist without early intervention.[1] Therefore, early detection and timely treatment of depressive symptoms in adolescents are crucial.[2] However, adolescents often struggle to identify these symptoms and even when they are aware of these symptoms, seeking help is not always their immediate response.[3]

OBJECTIVE

This study aimed to explore the relationship between passive digital data, specifically keystroke and stylus data collected via mobile devices, and the manifestation of depressive symptoms.

METHODS

A total of 927 first-year middle school students from a Seoul city-based school solved Korean language and math problems. Throughout this process, 77 types of keystroke and stylus data were collected, including parameters such as the number of key presses, speed, acceleration, length, and pressure. Depressive symptoms were measured using the self-rated PHQ-9.

RESULTS

Multiple regression analysis highlighted the significance of stroke length, speed, acceleration, the average y-coordinate, tap pressure, and the number of incorrect answers in relation to the scores on the depressive scale.

CONCLUSIONS

This study presents an important demonstration of the potential of automatically collected data during school exams or classes for the early screening of students' clinical depressive symptoms.
Redox Imbalance Theory of Disease, The Triple Oxidant Sink, and The Antioxidant Lifestyle
Authors: Carlson DuWayne , Wilson Christopher
Published: January 2024

Over 200,000 papers have been written in the last two decades focused on oxidative stress and disease. Much effort has gone into detailing disease associations with pathophysiologic pathways and mechanisms involved in oxidative stress. Supplements and foods have been studied to prevent or reverse this pervasive problem. While individual behaviors have been found to improve oxidative stress, no significant progress has been made toward a broad strategy to curb this disabler and killer. This article is aimed at providing a plausible oxidative-stress-related theory on disease causation. We then provide a multimodal approach aimed at preventing and mitigating the disease-causing inflammatory fallout from redox imbalance. Together the hypotheses provide a foundational framework for research to mitigate the effects of oxidative stress.

Цифровая трансформация стандартизации и контроля качества в строительном производстве на основе реализации реестрового принципа управления требованиями нормативно-технической документации
Authors: Звонов Илья Александрович
Published: January 2024

Обеспечение качества выполнения строительно-монтажных работ традиционно является приоритетной задачей строительной отрасли, а сегодня в условиях становления цифровой экономики выступает основой формирования критериев эффективности трансформационных процессов. Статья посвящена поиску путей развития методического инструментария цифровой трансформации стандартизации и контроля выполнения строительно-монтажных работ для широкого круга участников строительства. Масштабное применение технологий информационного моделирования и цифровых моделей на всех этапах жизненного цикла объектов капитального строительства, требует радикальных изменений в организации и развитии отраслевой нормативно-технической базы обеспечения качества. Во многом повышение качества строительно-монтажных работ зависит от лояльности проектировщиков и строителей к реестровому принципу технического регулирования. Автор ориентировался на критерии повышения качества проработки технологических процессов в строительстве. Для достижения цели автор предлагает в статье к рассмотрению концепцию формирования и применения реестров нормативных требований (РНТ), призванных изменить подход к работе с нормативным документом, в том числе при оценке качества предъявляемых строительно-монтажных работ (СМР), проводимых в соответствии с данным нормативом. Применяемые РНТ предполагают иную структуру информации, где ключевым элементом является именно требование. Структура требования содержит в себе числовые параметры, формируемые для конкретных процессов.

Концепция предполагает интеграцию реестров требований с информационной моделью здания, формирование запроса и применение выгружаемых из модели данных по перечню работ, их объемам, организационно-технологическим связям между работами и др.

Authors: Silva Felix Bruna , Crnkovic Octaviani Maria Inês , de Oliveira Falcão Freitas Rafaela
Published: January 2024

Entre os principais desafios no cenário atual da Educação Infantil, está o desenvolvimento integral do sujeito aprendiz. Essa discussão ganha maior relevância quando se considera a experiência de aprendizagem com o ensino remoto vivenciada durante a pandemia da covid-19. Desse modo, definiu-se como objetivos deste estudo: investigar as implicações das Tecnologias Digitais de Informação e Comunicação (TDICs) no desenvolvimento integral de crianças na etapa da Educação Infantil; compreender o contexto histórico acerca da evolução das tecnologias no ambiente educacional e do desenvolvimento da criança; identificar as possibilidades e contribuições da integração das tecnologias emergentes no contexto da Educação Infantil. Para tanto, foi realizada uma pesquisa bibliográfica, de caráter exploratório, com análise qualitativa dos dados. Verificou-se que a integração das tecnologias pode contribuir para o desenvolvimento das crianças quando as práticas pedagógicas buscam possibilitar as aprendizagens por meio de uma ação intencional e planejada de ensino.

Authors: Borges Moreira Thaís , Andrade da Silva Wanderson Diogo , Crosara Maia Leite Raquel
Published: January 2024

A vivência de pandemia, problemas climáticos e desastres ambientais experienciados com maior frequência nos últimos tempos fazem a humanidade refletir sobre como estamos lidando com o planeta. Com isso, a Educação Ambiental (EA) vem se tornando um caminho para auxiliar no processo de transformação das pessoas e futuros cidadãos. Assim, esta pesquisa buscou mapear e analisar estudos sobre EA no contexto da Base Nacional Comum Curricular (BNCC) na perspectiva da EA Crítica. A literatura foi mapeada a partir do Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) entre 2017 e 2022. Apenas 2 estudos foram selecionados diante dos critérios de busca, os quais revelam a incipiência dos estudos sobre EA Crítica no contexto da BNCC. Verificou-se que a literatura selecionada direciona para a necessidade de se estudar EA para formar cidadãos mais críticos e reflexivos, e a escola tem seu papel fundamental em tal mudança.
Desafios do conservadorismo nas políticas de inclusão do surdo negro: o resgate da memória para superar obstáculos
Authors: Meira Silva Wemerson , Ramos dos Santos Igor Tairone
Published: January 2024

Este artigo busca analisar os desafios enfrentados pelas políticas de inclusão de surdos negros no Brasil e seu prejuízo com o avanço do conservadorismo no Brasil, bem como destacar como a preservação da memória pode ser uma ferramenta para superar esses obstáculos. Partimos da premissa de que o crescimento das tendências conservadoras no Brasil tem impactado negativamente a luta contra o preconceito e prejudicado as políticas de inclusão, especialmente nas escolas sendo uma situação se agrava quando se trata de surdos negros, que além da surdez, ainda enfrentam preconceitos de raça. Utilizando uma abordagem qualitativa, fundamentada em autores como Silva (2011), Quadros (2004) e Santos e Obregón (2019), realizamos entrevistas semiestruturadas em uma escola da rede pública em Vitória da Conquista, Bahia. Nossos resultados indicam que os surdos negros enfrentam desafios significativos relacionados tanto à sua deficiência auditiva quanto à sua cor de pele. Nas entrevistas, também identificamos a falta de intérpretes de Libras como um dos principais problemas enfrentados por esses indivíduos. No entanto, acreditamos que o resgate da memória desses alunos e a promoção do compartilhamento e acesso às suas histórias de vida podem ser estratégias valiosas para combater a ausência de políticas inclusivas e resistir à crescente influência conservadora que avança no Brasil.
O que quer o currículo para a educação infantil? Um gesto analítico dos documentos da política curricular
Authors: Santos de Jesus Gilmara , Santos Pereira Reginaldo
Published: January 2024

Nesta investigação, foi tecida uma análise dos documentos curriculares para a Educação Infantil, a saber, o Referencial Curricular Nacional da Educação Infantil – RCNEI (1998), as Diretrizes Curriculares Nacionais da Educação Infantil – DCNEI (2009), a Base Nacional Comum Curricular – BNCC (2017) e seus engendramentos discursivos constitutivos da política curricular. Tais documentos demarcaram o contexto da Educação Infantil com o atravessamento dos seus discursos e que não trazem em si uma linha contínua das suas significações, mas revelam as continuidades, as rupturas, os liames e os entrelaços desse composto curricular. Ao diagramar-se a política curricular através dos documentos RCNEI, as DCNEI e a BNCC, percebeu-se que cada um foi elaborado sob forte influência do contexto histórico. Os saberes que se põe a falar sobre a criança e sua infância a partir dos RCNEI são os mesmos que vislumbram a Educação Infantil como etapa preparatória da escolarização. Na análise das DCNEI, percebe-se a ideia de Educação Infantil como etapa que fornece meios para progredir no trabalho e nos estudos posteriores. Já a BNCC, traz rupturas à política curricular para Educação Infantil, pois o que se põe em disputa no currículo evidencia-se no estabelecimento da gestão de competências e fixação de conteúdos.

Published: January 2024

O desenvolvimento de sobrepeso e obesidade está crescendo, e essa ocorrência é conhecida como uma pandemia do século XXI. O motivo que mais contribui para o surgimento da obesidade consiste no fácil acesso a comidas processadas, onde ocorre a instabilidade entre o consumo e o gasto energético ocasionando o aumento da gordura corporal. A microbiota intestinal equivale a uma condição ambiental que age no metabolismo de todo o corpo humano, influenciando o balanço energético, a inflamação e o papel da barreira intestinal, englobando sinais reguladores periféricos e centrais do consumo de alimentos e, deste modo, aumentando o peso corporal. A pesquisa avalia os achados científicos a respeito do conteúdo, ainda de caráter básica, natureza observacional, a forma de abordagem é qualitativa descritiva. Para a realização da revisão foram selecionados 9 artigos dentre as bases de dados, como objetivo de mostrar benefícios dos probióticos para obesos. De acordo com os critérios utilizados foi observado que a estratégia de prevenção e controle da obesidade por meio do uso de probióticos tem uma série de respostas favoráveis associado a práticas alimentares, pois os mesmos atuam no apetite e na homeostase energética resultando na redução de peso e da circunferência da cintura e quadril. Com isso, pode-se concluir que é relevante a realização de mais estudos sobre o tema já que algumas cepas de probióticos possuem um efeito positivo maior em conjunto com uma alimentação balanceada.
