Advantages of Using Databases in Linguistic Research
Authors:   Petrozavodsk State University, Lebedev A. A.
Published: February 2025

The paper examines special opportunities that databases provide for linguistic research. The role and significance of databases are analyzed using four specific projects that have been developed or are in the process of development with the active participation of the staff of the Russian Language Department of Petrozavodsk State University. The presented databases illustrate how an interdisciplinary approach, including close interaction of linguistics with information technology and other scientific disciplines, can enrich and simplify the research process. The paper emphasizes the advantages of this approach in collecting, systematizing and analyzing linguistic material, as well as in using the results obtained for further scientific research. One of the key aspects of the discussion is the fact that databases allow storing, processing and analyzing large amounts of information, which is difficult with traditional methods of work: databases simplify access to a wide range of linguistic data, allow to quickly and accurately find the necessary information, as well as to conduct multivariate analyses, which can increase the depth of research. Examples of additional capabilities, such as integration of data from different sources, semi-automated analysis and the ability to quickly update information, which are practically unavailable when using traditional approaches to working with material, are given. It is concluded that databases not only simplify the work of a linguist, but also open up new horizons for interdisciplinary research, providing innovative tools for solving complex problems in the field of linguistics.

Published: February 2025

Novel foods have recently gained increasing popularity. Given their diversity and nutritional values, which are comparable to commonly consumed foods, novel foods had to be regulated both in terms of the procedural stages required for market introduction at the European Union level, implicitly in Romania, and the requirements they must meet for safe consumption. The analysis methods used for their characterization are generally classic, standardized ones or can be developed "in-house", as is the case for methods developed for the determination of mycotoxins. The method of analysis used for the determination of mycotoxins involves high performance liquid chromatography coupled with a mass spectrometer (LCMSMS) after the prior extraction of mycotoxins using QuEChERS extraction. The novelty of recent years is the inclusion on the list of novel foods approved at the European Union level of laboratory-grown meat and insects, such as flour beetle larvae available in frozen, paste, or dried form, and house crickets, available in frozen, powdered or desiccated form.

Historia e identidad nacional contenida en videojuegos
Authors: Rodríguez Herrejón Guillermo Fernando
Published: February 2025

Los videojuegos son herramientas multifacéticas sumamente complejas y hoy en día su industria es una de las más importantes a nivel mundial. En los últimos años ha habido varios debates en torno a su eficacia como herramientas didácticas, ya que al ser altamente interactivos se puede aprender mucho con ellos, pero en muchas ocasiones se les mira con desconfianza. Los juegos comerciales contienen muchos elementos históricos y de identidad, pero tienden a ser inexactos, ya que su objetivo es entretener, sin embargo, también existen los que son creados exclusivamente con el propósito de servir como herramientas educativas. Por lo tanto, este trabajo tiene como objetivo ejemplificar algunos casos de juegos contemporáneos que contengan nociones de identidad nacional o contenidos históricos, para reflexionar sobre su importancia como medios de transmisión, ya que sin dudas ayudan a dibujar ideas de la realidad y deben ser catalogados como serious games. Específicamente se usarán casos de algunos esfuerzos hechos por profesionales, en historia y disciplinas afines, desde varios países de América Latina, como Argentina, Chile, Ecuador, México y Perú, para observar cómo se han construido proyectos educativos en años recientes utilizando esas nuevas tecnologías para el impulso de la identidad nacional.

Published: February 2025

Third trimester pregnant women are at risk of anaemia, which can increase the risk to the mother and fetus. Pregnant women in addition to taking Fe tablets, need to be supported by nutritional patterns that contain several intermediates for haemoglobin synthesis such as avocado/ambon banana. Avocado and banana ambon are enriched with iron which is effective in controlling iron deficiency, also contains vitamin C which helps increase iron absorption. This study was a quasi-experiment with two-group pretest-posttest. The population was anaemic pregnant women in the third trimester with a sample of 20 pregnant women. The sampling method used purposive sampling. The research instruments were SOP and observation sheet. Pregnant women consumed avocado juice or banana ambon juice once a day for 14 days. Data were obtained by measuring haemoglobin levels (Easytouch GCHb). The results showed that the average Hb level before avocado juice intervention was 9.12 g/dL and after 11.15 g/dL. The average haemoglobin level before the administration of ambon banana juice was 9.42 g/dL and after 10.78 g/dL. The effectiveness of avocado juice and ambon banana juice on increasing Hb levels in third trimester pregnant women with a ρ value of 0.025. Avocado juice increases the Hb level of pregnant women more than banana ambon juice. Anaemic pregnant women can use avocado juice or banana ambon juice to increase Hb levels.
Accounting without a General Ledger: Insights from Micro, Small and Medium Enterprises in Pakistan
Authors: Asif Jaffer Muhammad
Published: February 2025

: This study examines the formality of accounting practices within Pakistan's micro, small
and medium enterprises (MSMEs). Data was gathered from 110 MSMEs located in Karachi,
Pakistan. The research focused on eight dimensions of accounting systems: chart of accounts, payroll
records, receipt and payment records, party ledgers, employee time records, segregation of duties,
documentary support, and budgetary control. These dimensions were analyzed in relation to four
firm-level attributes: organization type, firm size, firm age, and type of business. The results indicate
that most firms do not utilize these accounting dimensions, a finding that is consistent across various
firm ages and business types. However, firm size shows some association with the utilization of four
of the eight dimensions. The implications of these findings are discussed in the context of agency and
institutional theories, and some policy recommendations are provided. Future research could use this
exploratory study to investigate the motivations and structural barriers that influence the adoption
or avoidance of formal accounting practices by MSMEs, as well as how these enterprises use
accounting information and the challenges they encounter

Democracy backsliding and populism. The crisis of the Mexican republic
Authors: Linas Amezcua Bryan Hassan , Vega Mondragón Miguel Ángel
Published: February 2025

Democratic erosion is a legal-social phenomenon that destabilizes Constitutional Republics due to the rise of so-called "populist" political leaders, who are legally (electoral law protects them) and legitimately (they have majority approval) elected; their objective is to destroy the institutional order contained in the Constitution to maintain their hold on power. Mexico is no exception; conflicts between the executive and the judiciary and constant attacks on independent organisms are currently putting federal democracy under strain. For this reason, this article is a documentary investigation that deals with the general concepts that give rise to the way political power is exercised. Using the historical method, it examines the evolution of forms of government; the Mexican nation has gone through three key and unstable events: empire, centralism and federalism, the latter of which served to found both democracy and the contemporary presidential system. Subsequently, it identifies the democratic fracture and rise of populism to describe its modus operandi. Finally, it is proposed to restructure the checks on power contained in the constitution relating to transparency, citizen participation and the powers of the branches of government.
AN APPROACH TO THE JOINT APPLICATION OF TWO METHODS OF ESTIMATION OF PARAMETERS OF A LINEAR REGRESSION MODEL
Authors:   Irkutsk State Transport University, Noskov Sergey I. , Chekalova Aleksandra R. ,   Irkutsk State Transport University
Published: February 2025

The paper provides a brief overview of publications on the use of trade-off solutions in regression modeling of complex objects related to both the methods of constructing models and their practical use in solving specific applied problems. In particular, the following are considered: a relative trade-off between accuracy in modeling hidden and observed variables; trade-off relations that follow from the known tight boundaries of quantum multiparameter estimation; a trade-off between model complexity and the quality of uncertainty assessment; a classical trade-off between bias and variance, when the bias decreases and the variance increases with increasing model complexity, although this is not always true; a trade-off between carbon emissions per capita and income inequality; a trade-off between the presence of emissions and recognition accuracy in the logistic regression model. An algorithm is proposed for finding a compromise between the least absolute value method in estimating unknown parameters of a linear regression equation and an alternative modeling method, which is reduced to solving a linear programming problem. Three alternative versions of a regression model for zinc mining in the Russian Federation are constructed. The following are used as independent variables: prices for refined zinc, financing of geological exploration work for zinc at the expense of subsoil users' own funds and of federal budget funds. At the same time, the estimates of the parameters of all three variants of the model change within relatively narrow limits

Saudi Students’ Perceptions Towards the Effectiveness of Code-Switching in EFL Online Classes
Authors: Algethami Abeer
Published: February 2025

The COVID-19 pandemic significantly transformed the education field worldwide, shifting the teaching-learning process from traditional face-to-face classrooms to online learning environments. However, online learning often lacks essential elements that facilitate an effective teaching process, such as physical interactions, gestures, body language, and facial expressions. Consequently, teachers struggled to connect with students and subsequently adopted code-switching (CS) which involves alternating between students’ first language (L1) and the foreign language (FL) in English language classrooms. This study examines EFL students’ perceptions of the effectiveness of CS in online classes. A quantitative research approach was employed, and data were collected via a web-based questionnaire completed by 72 third-year students who had completed English language courses online. The findings indicate that most undergraduate students had positive perceptions of CS in online English classes. The study provides the reasons for employing CS and its role in enhancing the learning process in virtual classrooms. However, the study’s limitations highlight the need for further investigation in future research.

Published: February 2025

La didactique comme discipline éducationnelle s’intéresse tant aux objets de savoirs qu’aux manières de les enseigner que l’on peut désigner comme des stratégies d’enseignement. Plusieurs classifications les répertoriant ont été publiées pour en réduire la complexité. Cet article propose une revue intégrative des classifications de stratégies d’enseignement dont l’objectif est d’identifier ce qu’elles contiennent et comment elles sont organisées afin de dégager des constats pour la recherche en didactique. Basée sur la méthode de recension des écrits de Whittemore et Knafl (2005) et sur la méthode PRISMA (Moher et al., 2009) pour la sélection des textes, nous avons procédé à une analyse critique de 14 classifications en s’appuyant sur les définitions des concepts de classification, de typologie et de taxonomie, ainsi que sur les composantes du modèle de la situation pédagogique de Legendre (1983). L’un des constats qui se dégage est que la composante Objet, soit les apprentissages potentiels que les stratégies d’enseignement peuvent engendrer chez les personnes apprenantes, est peu présente et appuyée dans les différentes classifications. Les angles morts dégagés des analyses sont ensuite discutés et conduisent à la proposition de pistes pour l’élaboration d’une éventuelle typologie tenant compte de cette revue intégrative.

Published: February 2025

Oaxaca, Mexico, coffee (Coffea arabica L.) received its denomination of origin "Pluma" (NOM-255-SE, 2022). Previous studies indicate that the intrinsic characteristics of coffee originate from chemical components that intervene in the organoleptic attributes evaluated during cupping. The objective was to analyze the physical and chemical attributes of medium roasted Coffea arabica L. beans from the farms: “La Virginia” (1058 meters above sea level; masl), “La Palma” (1149 masl) and “Nuestra Señora del Carmen” (1343 masl) located in the area of Pluma, state of Oaxaca, Mexico. The physical analysis was performed according to NOM 255-SE-2022, the chemical analysis was attached to the AOAC, 2012, the evaluation of the organoleptic quality was established with respect to the quality standards of the Specialty Coffee Association and the statistical analysis was carried out by Principal Component Analysis. The physical analysis shows that the beans from the "Nuestra Señora del Carmen" farm have greater integrity than the other two farms, categorizing them as "premium" quality. The chemical analysis allowed establishing the existence of a correlation between altitude and the content of lipids, proteins, and titratable acidity, which influence the sensory characteristics of the coffee beverage, mainly in the body and acidity.

Using hands-On Versus Virtual Manipulatives to Assist Basic Seven (7) Students in Understanding the Concept of Algebraic Expressions : A Case Study of Bagabaga Demonstration Junior High School
Authors: Sadiq Zakaria A. , Abdulai Nashiru , Dramani Abdulai B. , Ayamah Richard
Published: February 2025

This research study employs a quasi-experimental research design. The primary objective is to compare the effectiveness of hands-on and virtual manipulatives in enhancing the comprehension of the concept of algebraic expressions among Basic Seven (7) students at Bagabaga Demonstration Junior High School in Sagnarigu Municipality located in Tamale, Ghana. The research population comprised 100 students, selected through purposive and simple random sampling techniques. The population was divided into two groups: the Experimental group and the Control group. Prior to the intervention, both groups underwent a pretest, resulting in nearly identical mean and standard deviation scores (i.e.,1.08 and 1.44). Following the intervention, a Posttest was conducted to assess the impact of the intervention methods. The Experimental group achieved a mean score of 7.3, accompanied by a standard deviation of 5.9 while the Control group attained a mean score of 8.86, with a standard deviation of 1.5. These findings suggest that the use of hands-on and virtual manipulatives has a substantial influence on the understanding of the concept of algebraic expressions among the Bagabaga Demonstration Junior High School Basic Seven (7) students. The study recommends the use of diverse approaches which employ both hands-on and virtual manipulatives to address various learning styles, integrating them with other teaching strategies as well as continuous training of teachers to effectively integrate manipulatives into the classroom, and collaborate with colleagues to share best practices.

Starburst Galaxies in Their Last Billion Years: An Hδ Absorption Line Selected Sample
Authors: Wu Shumei , Huang Jia-Sheng , Cheng Cheng , Dai Y. Sophia
Published: February 2025

In this paper, we focus on the study of starburst galaxies in their final billion years. Our galaxy selection is based solely on the presence of the Hδ absorption line, which permits the later evolution of starburst galaxies to be traced, coinciding with the emergence of A-type stars in these galaxies. We propose a novel method that utilizes star formation rate and UVJ colors to classify galaxies in the sample, and use the spectral features to mark their stages of evolution. Our in-depth analysis of the Mg ii line indicates the substantial increase in the number of F- and G-type stars when a galaxy evolves from star-forming to quiescent phase. Furthermore, we identify active galactic nuclei in this sample to explore their roles in the later stage of the star formation history of galaxies.
Double Consciousness and Afro-Descent

Cet article propose une réflexion sur la condition noire en interrogeant l’application du concept de « double conscience » duboisien dans le contexte français contemporain. Il participe d’une étude qualitative et inductive réalisée sur le modèle de l’enquête de terrain et qui s’appuie sur des entretiens non directifs réalisés auprès de personnes afro-descendantes françaises. S’inscrivant dans une démarche interdisciplinaire, l’analyse psychanalytique que nous proposons se veut à la croisée de regards socio-historiques et philosophiques sur la condition noire en contexte français. Cette analyse met en lumière la prépondérance de la ligne de partage des couleurs dans la structure de nos sociétés modernes. Partant de là, elle rend compte de l’implication de cette ligne dans les processus de subjectivations des personnes afro-descendantes, de l’identification à la blancheur à la révolte sociale en passant par la guerre contre soi-même.
Hématopoïèse clonale de signification indéterminée et risque cardiovasculaire
Authors: Couffinhal Thierry , Leroy Harmony , James C. , Omnès Sophie
Published: February 2025

Le terme « hématopoïèse clonale de signification indéterminée » ( Clonal Hematopoiesis of Indeterminate Potential ou CHIP) désigne le fait d’acquérir au cours de la vie des mutations, associées au développement de leucémies, dans des cellules souches de la moelle osseuse (mutations somatiques), mais en absence de toute pathologie hématologique. Ce concept encore récent est le fruit de près de 50 ans de recherche qui ont permis de les caractériser et de comprendre, au moins partiellement, leurs conséquences. Les cellules souches hématopoïétiques mutées donnent ensuite naissance à des cellules sanguines matures normales, mais qui portent, elles aussi, la mutation. Les mutations identifiées au cours des CHIP peuvent affecter une grande variété de gènes, mais touchent le plus souvent ceux impliqués dans la régulation de l’expression génique comme DNMT3A, TET2 et ASXL1 . Pour retenir actuellement le diagnostic de CHIP, il faut qu’elle soit détectée à une fréquence d’au moins 2 % et que l’hémogramme ou le myélogramme ne présente aucune anomalie. La fréquence des CHIP augmente avec l’âge, près de 10 % des sujets de plus de 60 ans en étant porteurs. Elles sont associées à un surrisque de développer, non seulement une hémopathie maligne, mais aussi et de façon plus inattendue, un infarctus du myocarde ou un accident vasculaire cérébral. L’étude de modèles animaux a permis de démontrer que les macrophages portant la mutation impliquée dans la CHIP sécrètent plus de cytokines pro-inflammatoires, créant un environnement propice à l’athérosclérose et à un dysfonctionnement cardiaque. Les CHIP seraient donc un facteur de risque de maladies cardiovasculaires à part entière, dont la place reste à définir dans la stratégie diagnostique, thérapeutique et préventive de ces pathologies.

Contrairement à de nombreux lymphomes où l’étude anatomopathologique est prépondérante, les syndromes lymphoprolifératifs B sont des pathologies fréquentes où le biologiste médical est impliqué en première ligne. La connaissance des principales caractéristiques de chacune des pathologies classées par l’OMS est nécessaire afin que le diagnostic proposé au clinicien soit le plus précis possible, permettant évaluation du pronostic et mise en route du traitement le mieux adapté. L’objet de cet article est d’indiquer les principaux critères cliniques, morphologiques, immunophénotypiques, cytogénétiques et moléculaires de ces pathologies hétérogènes, en rappelant, sur différentes figures, les principaux aspects observables par le cytologiste.
Maladie de Verneuil, une affection cutanée reliée à un dysfonctionnement immunitaire de la peau
Authors: Nassif Aude
Published: February 2025

L’hidradénite suppurée, ou maladie de Verneuil, est une affection cutanée inflammatoire chronique et récidivante, dont le primum movens est l’occlusion d’un follicule pilo-sébacé par un bouchon de kératine (comédon). Ce dernier est responsable du piégeage et de la prolifération de bactéries commensales dans la racine du poil, entraînant secondairement des abcès se rompant dans le derme. La maladie se manifeste cliniquement par des nodules et des abcès douloureux, notamment dans les plis cutanés (axillaire, inguinal, interfessier). Relativement fréquente, avec une prévalence dans la population générale estimée à environ 1 %, elle atteint plus souvent la femme. Outre divers facteurs exogènes favorisant l’hidradénite suppurée, des anomalies génétiques lui sont également associées et contribuent à une altération de l’immunité locale de la peau à l’égard de la flore microbienne cutanée (microbiote). Elle est à l’origine de diverses antibiothérapies et biothérapies, bien que la chirurgie des lésions reste le traitement de référence, n’empêchant cependant pas l’extension de la maladie dans d’autres zones ; le meilleur traitement repose probablement sur la combinaison des deux stratégies.
Nueva demanda demográfica y escasez de vivienda en España: políticas de vivienda en una población postransicional
Authors: Módenes Juan A. , Marcos Mariana , García-García Diva Marcela
Published: February 2025

El artículo propone una reinterpretación desde la demografía de la evolución reciente del sistema español de demanda agregada de vivienda. Mientras que hasta hace poco se le podía considerar un sistema en cambio paulatino tendente a una demanda cero o negativa, en paralelo al proceso de envejecimiento, actualmente es evidente que la demanda es oscilante y, en ciertos momentos intensa y muy positiva. La demanda residencial demográfica se caracteriza por la sucesión de ciclos y crisis, y es determinada por olas inmigratorias y cambios en los comportamientos de formación de hogar. Empíricamente se ha descompuesto el crecimiento reciente de hogares de España en sus factores demográficos básicos: crecimiento demográfico, cambio en la estructura por edad, flujos migratorios y comportamiento de formación de hogares. La descripción de resultados constata que la oferta de nueva vivienda es cada vez más sensible a los puntos bajos de los ciclos de demanda demográfica, lo que tenderá a producir escasez si se consolida. Por último, se argumentará que se necesita, en coherencia con el cambio del sistema demográfico de demanda residencial, que las nuevas políticas de vivienda se orienten adecuadamente hacia asegurar una construcción suficiente en un entorno cíclico y de incertidumbre y hacia la gestión eficaz del parque de vivienda ya existente que asegure su uso demográfico.
Análisis y modelización de los cambios en la inundabilidad tras el incendio forestal de Sierra Bermeja en 2021 (Provincia de Málaga,España)
Authors: Gallegos Reina Antonio
Published: February 2025

En septiembre de 2021 se produjo en Sierra Bermeja (Málaga) uno de los mayores incendios forestales acaecidos en Andalucía en los últimos años. Más allá del daño biológico en una zona de gran importancia ecológica, en regiones mediterráneas existe también una correlación muy directa entre incendios e inundaciones. Este trabajo analiza la afección potencial que ha tenido el incendio sobre la inundabilidad en los municipios del entorno. Para ello, desarrolla dos líneas metodológicas, consistentes en evaluar la escorrentía previa y posterior al incendio, y modelizar diacrónicamente las láminas de inundación en las principales cuencas hidrográficas afectadas. Para orientar los estudios hidrológico-hidráulicos y para testar los resultados se ha tomado como referencia un evento tormentoso posterior al incendio, que ocasionó importantes inundaciones. Los resultados coinciden con los registros de dicho evento, por lo que la metodología podría ser de utilidad para orientar las acciones de gestión y ordenación territorial que las administraciones pueden y deben llevar a cabo tras grandes incendios en regiones mediterráneas.

Illustration as Transmission: Leslie Saalburg and The Ambassadors
Authors: Leroy Maxime
Published: February 2025

L’article porte sur les illustrations de Leslie Saalburg réalisées au début des années 1960 pour Les Ambassadeurs de Henry James. Saalburg était un illustrateur reconnu qui travaillait pour des magazines consacrés à la mode, aux voyages ou aux automobiles. Cette commande de The Limited Editions Club semble avoir été sa seule contribution à l’illustration littéraire. La première partie de l’article montre comment les aquarelles de Saalburg empruntent à l’illustration commerciale et reflètent ses idées conservatrices sur l’élégance vestimentaire, dans le contexte d’une nostalgie pour l’époque édouardienne durant les années 1960. En lien avec la place centrale du vêtement, la deuxième partie compare la façon dont les illustrations et le texte de James mettent en scène le regard de Strether, protagoniste et focalisateur du récit, dans son rapport à la fois fétichiste et magique à certains personnages féminins. Il est montré qu’en raison du parti pris conservateur de Saalburg, les illustrations ignorent le concept de formes évolutives de transmission sociale à l’œuvre dans le roman. La troisième partie prolonge cette analyse en montrant la dimension interpictoriale de certaines planches, et en s’appuyant sur la notion de « façons de voir » de Charles Goodwin. Elle se termine par l’idée que l’échange de regards dans les illustrations, confiné aux interactions entre individus d’un même milieu, contourne la représentation jamesienne des tensions entre communautés sociales ou épistémiques opposées.
