Published: January 2025

The study aimed to determine the placebo marketing towards consumer expectation and product integrity among health supplement users in Cavite. This also determines the participants' perception of placebo effect marketing in their consumer expectation about the performance and reliability of the product, ease of use, value for money, and emotional connection towards its consumers. The participant's perception of placebo effect marketing on product integrity in terms of transparency and expectation versus reality. It employed a descriptive-correlational research design using a survey questionnaire administered through Google Forms, considering 120 health supplement users in Cavite. For this study, the researcher also used statistical methods including frequency distribution, mean, percentage, and standard deviation. A Likert scale that used to assess participants' perceptions of marketing strategies and their influence on health supplement use and expectations. Results show that the participants towards the placebo marketing strategies have effectively created a positive initial impression among health supplement users in Cavite. These strategies, such as professional endorsements, scientific language, and attractive packaging, make products seem reliable and valuable. This means that while marketing can create strong first impressions, it is difficult to keep these impressions once the product is used. Results also show a gap between what the marketing promises and what the products actually deliver and to keep consumers' trust and uphold the brand's integrity, companies need to ensure that their marketing claims match the actual benefits of their products. For the sake of brand integrity, businesses should prioritize transparency in product labeling by providing clear and accurate information about ingredients, testing procedures, and certifications. For consumers, it is recommended to remain critical and informed when evaluating health supplement claims. The study emphasizes the need for ethical marketing practices to foster trust and loyalty in the health supplement industry.

This study examined the impact of AI-driven learning platforms on academic engagement and achievement among Business Administration students at Cavite State University-Tanza Campus. It contributes to the body of knowledge on how AI-powered learning platforms influence academic engagement, achievement, learning environment quality, and overall educational effectiveness. The researcher employed a quantitative research method, collecting data through a structured survey. A total of 200 Business Administration students participated, chosen to represent a cross-section of the student population, ensuring that the results reflected a broad range of opinions and experiences regarding AI-driven learning platforms. To gain a comprehensive understanding of the demographic background, the survey included questions on age, gender, academic year, and prior experience with technology and online learning. The data was analyzed using statistical tools, including standard deviation, weighted mean, frequency, and percentage. The findings indicated that students recognize the value of these platforms in enhancing their academic engagement and performance. The majority of students strongly believe that these platforms enrich their educational experience by providing personalized content and immediate feedback, which foster greater motivation and active participation. Additionally, the data highlighted the platforms' ability to adapt to individual learning needs and offer real-time support, leading to more effective learning outcomes. However, while the platforms are seen as effective in motivating students and improving engagement, there is still room for improvement, particularly in fostering higher-order thinking skills such as critical thinking. Further development of AI algorithms to accommodate a broader range of learning styles and needs could enhance the overall effectiveness of these platforms. Furthermore, AI-driven platforms should be integrated with traditional teaching methods to provide a more balanced and holistic learning experience, ensuring that students benefit from both personalized and conventional educational approaches.

Published: January 2025

The demand for renewable energy technologies has surged due to the global energy transition and the push for decarbonization. This study explores the development of a Hybrid Renewable Energy System (HRES) combining solar and wind energy, focusing on selecting an optimal location in Malaysia based on available resources and analyzing its power generation and efficiency. A site study using anemometers and pyranometers was conducted from 8 am to 5 pm over five days, and SMath Studio was employed for mathematical modeling to determine average wind speed at varying heights, wind energy density, peak sun hours, and the optimal photovoltaic (PV) panel angle. The HRES, consisting of a Savonius turbine blade and a thin-film PV panel, was installed atop the Fakulti Kejuruteraan Alam Bina academic building. The wind turbine achieved an average power output of 0.2129 W, producing 5.11 Wh/day, while the PV panel generated 6.9083 W, yielding 43.45 Wh/day. Combined, the HRES produced 48.56 Wh/day with an efficiency of 7.02%. The findings demonstrate the suitability of the Savonius turbine for low wind speeds and the effectiveness of solar panels under high irradiance conditions. Although the system's overall efficiency was low, it successfully stabilized power output, determined optimal resource utilization, and provided valuable insights into hybrid energy generation. This study offers practical guidelines for developing dual renewable energy systems and advancing sustainable energy solutions.

Diesel and Oxyhydrogen Dual-Fuel: Reducing Emissions of a Diesel Engine using Diesel-Oxyhydrogen Dual Fuel Combustion
Authors: Mulk Waqad Ul , Abd Aziz Abd Rashid , Ismael Mhadi A. , Ghoto Asghar Ali
Published: January 2025

Diesel engines are frequently used because of their high efficiency and durability. However, they are also known for emitting high amounts of pollutants, including CO2, CO, NOx and particulate matter. Current studies have focused on alternate fuel techniques to reduce these emissions. An effective method involves using oxyhydrogen (HHO) with diesel and biodiesel can increase combustion efficiency and minimize harmful emissions. Additionally, HHO serves as a viable alternative to hydrogen, especially considering the current challenges in global hydrogen production and storage, which may not be sufficient to meet the increasing demand for transportation applications. Hence, the current study investigated the effect of using a diesel-HHO dual fuel on the emission characteristics of a single-cylinder, four-stroke diesel engine. The engine was operated at a constant speed of 1500 rpm and was tested under varying loads of 0%, 50% and 75%, with diesel (D100) serving as the primary fuel and HHO gas as the inducted fuel. The HHO gas, produced at a constant flow rate of 0.80 LPM through alkaline water electrolysis was continuously injected into the combustion chamber through air suction manifold. The results revealed that compared to diesel fuel, the injection of HHO has increased the CO2 emissions by 23.08, 23.81 and 20.0% at an engine load of 0, 50 and 100%. The CO emissions were reduced by 23.53, 34.78 and 41.38% at 0, 50 and 100% engine load. Similarly, the HC emissions were reduced by 26.09, 23.08 and 23.33% at 0, 50 and 100% engine load. The NOx emissions were increased by 25.0, 10.53 and 4.17% at 0, 50 and 100% engine load. Overall, introducing HHO has increased the CO2 and NOx emissions as the hydrogen and additional oxygen in the HHO gas promote more complete combustion and higher combustion temperatures. However, this enhancement in combustion efficiency has resulted in a significant reduction in CO and HC emissions.

Authors: Akande Roseline , Olarewaju Sunday , Adeomi Adeleye , Akande Joel , Oke Funmilola , Ige Roseline , Abodunrin Olugbemiga
Published: January 2025

Objectives: The choice of healthcare facilities is determined by the interaction of several factors and the perceived quality of care provided in the facilities. This study aimed to assess the factors influencing the choice of service providers among NHIS enrollees in public and private health facilities in Southwestern Nigeria.
Methods: A cross-sectional and mixed-method study design using both qualitative and quantitative data collection methods. Using a multistage sampling technique, 300 patients were enrolled. Four focus groups with eligible respondents were conducted in public and private health facilities. IBM SPSS was used to analyze the data, and a p-value of less than 0.05 was designated as the significance level. Qualitative data were collated and analyzed using detailed content analysis.
Results: The study found that 50 (33.3%) public and 37 (24.7%) private health facilities respondents had ever changed their health care providers respectively, but this was not statistically significant (p=0.098). Determinants of choice of healthcare providers among the public and private health facilities enrollees include; use of facility before joining the scheme (p<0.001), courteous/friendly hospital staff (p=0.042), adequate personnel and equipment (p=0.002), skills and expertise of personnel (p=0.03), use of health facility by majority of colleagues, (p<0.001) and spending greater than 10 years in the scheme (p=0.007).
Conclusion: Factors influencing the choice of healthcare providers among respondents in public and private health facilities, were mainly health facility related. Accredited healthcare providers seeking to improve the enrollment of new clients as well as retain their old clients should address these factors.
Discrete universality theorem for Matsumoto zeta-functions and nontrivial zeros of the Riemann zeta-function
Authors: Nakai Keita
Published: January 2025

In 2017, Garunkštis, Laurinčikas and Macaitienė proved the discrete universality theorem for the Riemann zeta-function shifted by imaginary parts of nontrivial zeros of the Riemann zeta-function. This discrete universality has been extended to various zeta-functions and L-functions. In this paper, we generalize this discrete universality for Matsumoto zeta-functions.

Using data from the Large Area Multi-Object fiber Spectroscopic Telescope Medium-Resolution Spectroscopic Survey of Nebulae, we create a sample of 17,821 diffuse ionized gas spectra in the anticenter region of the Milky Way by excluding fibers in the directions of H ii regions and supernova remnants. We then analyze the radial and vertical distributions of three line ratios ([N ii]/Hα, [S ii]/Hα, and [S ii]/[N ii]), as well as the oxygen abundance. [N ii]/Hα and [S ii]/Hα do not exhibit a consistent, monotonic decrease with increasing Galactocentric distance (R
gal). Instead, they show enhancement within the interarm region, positioned between the Local Arm and the Perseus Arm. [S ii]/[N ii] has a radial gradient of 0.1415 ± 0.0646 kpc−1 for the inner disk (8.34 < R
gal < 9.65 kpc) and remains nearly flat for the outer disk (R
gal > 9.65 kpc). In the vertical direction, [N ii]/Hα, [S ii]/Hα, and [S ii]/[N ii] increase with increasing Galactic disk height (∣z∣) in both southern and northern disks. Based on the N2S2Hα method, which combines [S ii]/[N ii] and [N ii]/Hα, we estimate the oxygen abundance. The oxygen abundance exhibits a consistent radial gradient with R
gal, featuring a slope of −0.0559 ± 0.0209 dex kpc−1 for the inner disk and a similar slope of −0.0429 ± 0.0599 dex kpc−1 for the outer disk. A single linear fitting to the entire disk yields a slope of −0.0317 ± 0.0124 dex kpc−1. In the vertical direction, the oxygen abundance decreases with increasing ∣z∣ in both southern and northern disks.

From these abundances, we place an upper limit on the carbon-to-oxygen ratio for HD 143105 b, C/O < 0.2 at 95% confidence, and find the atmospheric metallicity is approximately 0.1 × solar. The low metallicity may be responsible for the lack of a thermal inversion, which at the temperature of HD 143105 b would likely require significant opacity from TiO and/or VO. With these results, HD 143105 b joins the small number of nontransiting hot Jupiters with detected atmospheres.

Published: January 2025

We estimate the Einstein-radius-enclosed total mass for 177 cluster-scale strong gravitational lenses identified by the ChicagO Optically selected Lenses Located At the Margins of Public Surveys (COOL-LAMPS) collaboration with lens redshifts ranging from 0.2 ⪅ z ⪅ 1.0 using the brightest-cluster-galaxy (BCG) redshift and an observable proxy for the Einstein radius. We constrain the Einstein-radius-enclosed luminosity and stellar mass by fitting parametric spectral energy distributions to aperture photometry from the Dark Energy Camera Legacy Survey (DECaLS) in the g-, r-, and z-band Dark Energy Camera filters. We find that the BCG redshift, enclosed total mass, and enclosed luminosity are strongly correlated and well described by a planar relationship in 3D space. We find that the enclosed total mass and stellar mass are correlated with a logarithmic slope of

In tandem with the small radii within which these slopes are constrained, this may suggest invariance in baryon conversion efficiency and feedback strength as a function of cluster-centric radii in galaxy clusters. Additionally, the correlations described here should have utility in ranking strong-lensing candidates in upcoming imaging surveys—such as Rubin/Legacy Survey of Space and Time—in which an algorithmic treatment of strong lenses will be needed due to the sheer volume of data these surveys will produce.
Discrepancies between JWST Observations and Simulations of Quenched Massive Galaxies at z > 3: A Comparative Study with IllustrisTNG and ASTRID

Published: January 2025

Recent JWST observations have uncovered an unexpectedly large population of massive quiescent galaxies at z > 3. Using the cosmological simulations IllustrisTNG and ASTRID, we identify analogous galaxies and investigate their abundance, formation, quenching mechanisms, and post-quenching evolution for stellar masses

. We apply three different quenching definitions and find that both simulations significantly underestimate the comoving number density of quenched massive galaxies at z ≳ 3 compared to JWST observations by up to ∼2 dex. In both simulations, the high-z quenched massive galaxies often host overmassive central black holes above the local M
BH–M
⋆ relation, implying that AGN feedback is key in quenching galaxies in the early Universe. The typical quenching timescales for these galaxies are ∼200–600 Myr. IllustrisTNG primarily employs AGN kinetic feedback, while ASTRID relies on AGN thermal feedback at z > 2.3, which is less effective and has a longer quenching timescale. Although these simulations differ in many aspects, making a direct comparison challenging, our findings suggest the need for improved physical models of AGN feedback in galaxy formation simulations. At lower stellar masses, the quenched galaxies have denser local environments than the star-forming galaxies, suggesting that environmental quenching helps quench less-massive galaxies. We also study the post-quenching evolution of the high-z massive quiescent galaxies and find that many experience subsequent reactivation of star formation, evolving into primary progenitors of z = 0 brightest cluster galaxies.
Electron Acceleration by Multiple Fast Fermi Reflections at Earth’s Bow Shock
Authors: Liu Y. Y. , Cao J. B. , Liu C. M. , Song Y. T. , Hu D. K.
Published: January 2025

The generation of energetic particles in the Universe is an important topic in astrophysical and space physics. Although the diffusive shock acceleration has been acknowledged to play an essential role in particle acceleration, the injection problem has not been well resolved yet. Using measurements from the Magnetospheric Multiscale spacecraft, we report unexpected spiky enhancements of energetic electron flux in the upstream region of the Earth’s bow shock. Such enhancements are then demonstrated to result from the accelerated electron population by shock reflection. Meanwhile, the magnetic field exhibits no variations except an increase in radius of curvature. Based on the results above, we uncover the underlying acceleration scenario. When the interplanetary magnetic field with a proper curvature approaches the bow shock, the two ends of a magnetic field line may touch the shock front earlier than its middle part. Magnetic mirror points form at the two field-line-shock intersections. The solar wind electrons are therefore trapped and bounce between two mirror points. Eventually, these electrons undergo fast Fermi reflection several times and gain substantial energies. The spacecraft observation of accelerated electrons is reproduced with a numerical method based on the reflection model. Such an acceleration process may be a potential solution to the injection problem.
Hot Jupiters Are Asynchronous Rotators
Authors: Wazny Marek , Menou Kristen
Published: January 2025

Hot Jupiters are typically assumed to be synchronously rotating, from tidal locking. Their thermally driven atmospheric winds experience Lorentz drag on the planetary magnetic field anchored at depth. We find that the magnetic torque does not integrate to zero over the entire atmosphere. The resulting angular momentum feedback on the bulk interior can thus drive the planet away from synchronous rotation. Using a toy tidal–ohmic model and atmospheric general circulation model outputs for HD189733b, HD209458b, and Kepler7b, we establish that off-synchronous rotation can be substantial at tidal–ohmic equilibrium for sufficiently hot and/or magnetized hot Jupiters. Potential consequences of asynchronous rotation for hot Jupiter phenomenology motivate follow-up work on the tidal–ohmic scenario with approaches that go beyond our toy model.
IgG-Mediated Food Intolerance in a Patient with Allergic Symptoms, Acne and Obesity - Effect of Elimination Diet
Authors: Andjelković Marija , Vojvodić Aleksandra , Dikić Nenad
Published: January 2025

BACKGROUND: Although the association of food-specific IgG with the development and progression of specific diseases has been shown by many studies, strong correlations are still under question.  Are these antibodies a normal immune response to foods, or is the pathogenetic mechanism triggered in another way? Why do elimination diets improve, in many studies, different diseases at different ages?
CASE PRESENTATION: We will present the case of a patient who experienced significant improvement in allergic symptoms and reduced body weight by implementing an elimination diet. Type III hypersensitivity reactions are associated with IgG antibodies. They are considered to be normal reactions to food antigens. They are absorbed into the bloodstream in small amounts. However, immediately after a meal, antibodies and food antigen complexes bound to specific IgG circulate in the serum, rapidly cleared by a healthy immune system, specifically the reticuloendothelial system. If large amounts of antibodies are produced and immune complexes are deposited in the blood vessels of various organs and organ systems, various manifestations may occur.
CONCLUSION: This is a new field of medicine. Further research, better-standardized tests, and much more extensive studies are needed to prove how to utilize the IgG antibody-based elimination diet properly.

Cinquante ans de rapprochements entre EFTS et enseignement supérieur
Authors: de Montalembert Marc
Published: January 2025

De 1968, premières grèves des étudiants en travail social, à 1978, création du dsts, de nombreuses actions vont faire évoluer les rapports entre efts et universités : la loi Edgar Faure sur l’enseignement supérieur, la loi Delors sur la formation continue, le numéro de la revue Esprit « Normalisation et contrôle social (pourquoi le travail social ?) », le riff-ts de Jacques Beauchard et la création des maîtrises de sciences sociales appliquées au travail, le réseau des Hautes Études des pratiques sociales d’Henri Desroche, ou encore les initiatives d’Éliane Leplay avec le comité de liaison des centres de formation permanente et supérieure. Dès cette période et notamment dans les années suivantes, de nombreux projets communs vont rapprocher les efts et les universités, mais c’est surtout à partir du processus de Bologne (lmd) en 1999 que les universités vont évoluer et contribuer aux grands changements du secteur du travail social (création de l’unaforis, de la chaire du travail social au Cnam, renouvellement des formations, adossements de certains diplômes au grade de licence). Les conventions et le travail conjoint vont largement se développer, mais la question de la recherche (en, dans, sur le travail social) et l’interrogation autour d’un champ disciplinaire du travail et de l’intervention sociale cristallisent toujours les positions.
Entre écoles de travail social et universités, la voie diplomatique
Authors: Ravon Bertrand
Published: January 2025

En tant qu’université de sciences humaines et sociales, l’université Lumière Lyon 2, qui vient de fêter ses 50 ans, a toujours tissé des relations étroites avec le monde du travail social et incidemment celui de ses centres de formation. Ce n’est pourtant qu’à partir des années 2000 que l’on peut rendre compte du processus d’institutionnalisation d’une filière de formation universitaire des travailleurs sociaux, du niveau bac (daeu) au doctorat, en passant par les licences de sociologie et de sciences de l’éducation option « travail social », le master Intervention et développement social couplé au deis et plusieurs du (diplômes universitaires). En revenant sur l’un des différents dispositifs de formation auxquels il a participé, l’auteur cherche à tirer les leçons de ces expériences. Leçons interinstitutionnelles tout d’abord, marquées par la dynamique prudentielle et dialogique des(dés)accords, faite de tâtonnements et de délibération patiente qu’il a fallu entretenir pour construire des alliances durables avec les efts partenaires. Leçons épistémiques ensuite, inscrites dans une dynamique de formation par la recherche consacrée à l’expérience professionnelle des travailleurs sociaux, dynamique qui s’est imposée progressivement grâce à l’analyse partagée des interdépendances des savoirs académiques et de métier. En découle une démarche originale de formation universitaire des travailleurs sociaux, centrée sur l’enquête en situation de stage, comme double mouvement de recherche et de professionnalité.

This study investigates the storage properties and sensory evaluation of palm-based chocolate spreads formulated with sunflower wax (SFW) and carnauba wax (CW) in a wide range of temperatures. Hardness, spreadability and stability assessments of chocolate spreads with 3.5% SFW and 3.5% CW were made over a 24-week storage period. The hardness, spreadability and stability of the chocolate spreads were analyzed by means of Texture Analyzer, observation and LUMiFuge Stability Analyzer, respectively. A sensory evaluation of these chocolate spreads was conducted using a 7-point hedonic scale. The hardness of both chocolate spreads was influenced by low temperatures of 5-10 °C during the storage study. Decreasing and increasing trends were observed for samples stored at 5 and 10 °C, respectively. However, both palm-based chocolate spreads remained spreadable at 5 °C even after 24 weeks of storage. Both chocolate spreads demonstrated stability at 40 °C after 24 weeks of storage. The sensory evaluation revealed that chocolate spread with 3.5% CW was the most widely accepted by sensory panelists. Therefore, chocolate spread with 3.5% CW has the potential to be utilized over a wide range of temperature applications of 5-40 °C.
Analyzing and Mitigating Attacks in IoT Smart Home Using a Threat Modeling Approach-Based STRIDE
Authors: Ouaissa Mariya , Ouaissa Mariyam
Published: January 2025

The Internet of Things (IoT) is a network of interconnected devices that enables data exchange. It is widely used in areas such as healthcare, aviation, agriculture, energy, and home automation. Despite its rapid growth and the massive adoption of connected devices, IoT presents significant security risks. Traditional threat modeling approaches are insufficient to address these risks. Architecture-based modeling is recommended, as it considers the entire system and helps in understanding potential threats. Threat modeling is a systematic technique used to identify and evaluate potential threats that could compromise the security of a system. The main objective is to understand the vulnerabilities of a system in order to design appropriate security measures to mitigate them. This paper aims to analyze and mitigate specific IoT smart home threats using the STRIDE threat modeling framework, which systematically identifies potential vulnerabilities at the development level. By applying STRIDE, which stands for Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege, we focused on addressing key security threats, including denial of service (DoS), phishing, and man-in-the-middle (MitM) attacks. Our findings demonstrate that the proposed mitigation strategies are effective in countering these threats, providing a robust security layer for IoT smart homes. Through this study, we highlight the importance of architecture-based threat modeling to enhance security within the IoT ecosystem and offer practical solutions that strengthen IoT smart home resilience. The outcomes of the STRIDE-based analysis and the effectiveness of the mitigation techniques are detailed, offering empirical evidence to support our approach.
Navigating Noise: A Stratified Model for Scholarly Digital Editions of Arabic Manuscripts in Hebrew Script
Authors: Lanza Valentina B.
Published: January 2025

Cet article examine le rôle des éditions numériques savantes dans le développement de la recherche textuelle, en se focalisant sur le judéo-arabe, une variété linguistique unique utilisant l’alphabet hébreu pour représenter l’arabe. Nous proposons un modèle stratifié pour les éditions numériques savantes, visant à gérer les complexités orthographiques du judéo-arabe, notamment la transcription, la conversion de l’écriture, la normalisation et l’intégration des métadonnées. L’étude souligne l’importance cruciale de la gestion du « bruit » dans l’édition des textes, particulièrement lors de l’acquisition des données, où toute distorsion ou omission d’éléments orthographiques peut compromettre l’intégrité scientifique. Une étude de cas portant sur un manuscrit médiéval en judéo-arabe illustre l’application de ce modèle, en montrant comment il préserve l’intégrité textuelle tout en enrichissant l’analyse scientifique. Cette méthodologie aborde non seulement les défis spécifiques au judéo-arabe, mais elle est également adaptable à d’autres systèmes allographiques.
Transcription automatique des interactions verbales. Limites observées et perspectives envisagées à partir d’un corpus de consultations médicales
Authors: Bertin Thomas , Quellec Gwenolé
Published: January 2025

Les applications de transcription automatique de l’audio vers un texte écrit (par ex. Whisper) ont fait de fulgurants progrès ces dernières années. Cependant, généralement destinées à produire des textes conformes aux normes de l’écrit, elles tendent à gommer toute marque de l’oralité (ex. : répétitions, pauses dans le flot de paroles, phatiques comme euh…). Ainsi, même si elles laissent envisager des bénéfices importants en temps de travail comme en fidélité de transcription, elles restent globalement inadaptées pour les chercheurs analysant des interactions verbales. À partir d’un échantillon de transcriptions de consultations pré-opératoires en vue d’une intervention de neurochirurgie en conditions éveillées (recherche en cours), l’étude se donne trois objectifs : (i) recenser les difficultés que pose une application comme Whisper du point de vue d’un interactionniste de la parole ; (ii) expliciter l’origine de ces difficultés ; (iii) proposer des pistes pour les surmonter.
Quelle solution pour améliorer les performances de la reconnaissance d’entités nommées sur des données bruitées, corriger l’entrée ou filtrer la sortie ?

Published: January 2025

Cet article présente les résultats d’un travail de recherche qui vise à déterminer si la correction de l’OCR, en amont, permet d’améliorer significativement les résultats de la tâche de la Reconnaissance d’Entités Nommées (REN). Les expériences ont été appliquées aux corpus ELTeC et Très Grande Bibliothèque (TGB). Notre objectif est d’établir (i) une typologie des contaminations d’OCR issues des outils Kraken et Tesseract et (ii) une typologie des erreurs de la correction automatique produite par l’outil JamSpell. Dans le cadre de notre évaluation, nous étudions les intersections entre les EN détectées par l’outil spaCy dans les textes de référence et les deux versions d’OCR d’une part, et d’autre part la mesure cosinus utilisée pour calculer la distance textuelle entre ces versions. Nos résultats montrent que la correction automatique introduit des biais dans les données textuelles et que le filtrage des entités en sortie semble être une piste plus prometteuse. Enfin, nous constatons que les EN incorrectes sont massivement des entités courtes et hapax en corpus, ainsi que la longueur des entités et la fréquence documentaire sont les critères discriminatoires pour exclure des EN candidates avec une précision de plus de 98 %.
Élaboration de corpus pour l’enseignement de la grammaire : le corpus du jeu PP L’archer de Alloprof
Authors: Gauvin Isabelle , Leblanc Samuel , Martineau Marion Deslandes , Tanguay Marc-Antoine
Published: January 2025

Les corpus en didactique de la grammaire sont peu étudiés, alors qu’ils apparaissent centraux pour soutenir l’enseignement et, surtout, l’apprentissage de notions grammaticales. Après avoir clarifié leur rôle dans l’enseignement et dégagé les caractéristiques d’un corpus bien construit, nous analysons le corpus du populaire jeu numérique PP L’archer de la plateforme Alloprof. Nous constatons qu’il comporte un nombre limité de phrases et qu’elles manquent de diversité dans leur construction. Nous discutons de la pertinence de nos constats pour l’amélioration de la version du jeu en ligne et, plus largement, pour l’amélioration des corpus grammaticaux présentés aux élèves.
“Everything moves, ever forward”: Motherhood and Midlife in Pamela Adlon’s Better Things
Authors: Columpar Corinn
Published: January 2025

This article reads Pamela Adlon’s Better Things (FX, 2016-2022) as the relatively rare television series that foregrounds a mother’s drama, as opposed to that of her child/ren, and thereby represents midlife as a period of ongoing change. More specifically, it draws on discussions of televisual aesthetics, feminist cultural production, and maternal experience and subjectivity in order to explore the series’s representation of protagonist Sam—and, by extension, creator Adlon—as a self in process, developing in dynamic interaction with her career, desires, physiology, and community of family and friends. In the process, it focuses on certain defining features of Better Things, including its fragmented structure, which sidesteps the demands of both episodic and serial form; its maternal aesthetics, which I dub a televisual aesthetics of interruption; and its increasingly greater interest, over the course of a five-season run, in the experience of aging.
Public disconnection and private expansion: Digital privatization of village-level administration in India
Authors: Dahdah Marine Al , Alam Javed
Published: January 2025

Indian Administration has long been portrayed as ineffective, corrupt, and uncaring. An image that the government has been trying to fix for the past 15 years in part through the National e-governance plan and “Digital India” programme that are contributing to the massive digitalisation of India’s administration in the name of development. Cornerstone of this digital transformation, Common Service Centres (CSCs) seek to ensure the last mile of the Government-citizen relationship in every village of India. Using state-funded digital infrastructure - such as Aadhaar, UPI, eDistrict and eSevai platforms – these Internet centres are intended to serve as vital links between citizens and government services, providing access to public services. However, this digital layer has made the State services increasingly expensive for millions of people, preventing them from accessing essential services such as healthcare, education and food. Unique point-of-sales for digitised State services as well as bottom-of-the-pyramid private services, CSCs became unavoidable fee-based intermediaries of administrative work.

Published: January 2025

The proposed chapter delves into the implementation and outcomes of a pilot study conducted in a tertiary hospital setting focusing on competency-based training for healthcare professionals in the context of caring for patients with oropharyngeal dysphagia. Oropharyngeal dysphagia, a condition characterized by difficulty swallowing, poses significant challenges for patients and healthcare providers alike. Addressing the complexities of dysphagia care requires a multidisciplinary approach involving various healthcare professionals, including speech therapists, nurses, nutritionists, and physicians from diferente specyalitties. This chapter aims to elucidate the mission and concerns surrounding competency-based training in this specialized area. By fostering interdisciplinary collaboration, healthcare institutions can work towards building a competent and adaptable workforce capable of addressing the diverse and evolving needs of patients across all areas of healthcare
Comparative evaluation of aircraft joint stiffness between intermediate and high level of detail models
Authors: Santos Marco Tulio dos , Greco Marcelo
Published: January 2025

The present work aims to compare results in aircraft joints, focusing on spar and skin regions, considering two levels of detail to understand the differences in the structural response using different types of modeling (numerical and semi-amalytical Rutman approach). Several studies were already performed to obtain the correct understanding of how actual loads are distributed through the joints. Finite Element Analysis modeling made using Nastran software were performed here. The study has shown the differences between the models analyzed by comparing the stiffness of the fasteners at the specific region analyzed. Results indicate good agreement between models for translational stiffness and more significant differences for rotational stiffness. The finite elements model with high level of detail presents larger rotational stiffness when compared with the Rutman approach.
