Authors: Yan Harry Yaojun , Morrow Garrett , Yang Kai-Cheng , Wihbey John
Published: January 2025

We surveyed 1,000 U.S. adults to understand concerns about the use of artificial intelligence (AI) during the 2024 U.S. presidential election and public perceptions of AI-driven misinformation. Four out of five respondents expressed some level of worry about AI’s role in election misinformation. Our findings suggest that direct interactions with AI tools like ChatGPT and DALL-E were not correlated with these concerns, regardless of education or STEM work experience. Instead, news consumption, particularly through television, appeared more closely linked to heightened concerns. These results point to the potential influence of news media and the importance of exploring AI literacy and balanced reporting.

To reduce economic and social losses, a geriatric service has been introduced in the Russian Federation, focusing on maintaining the functionality of an older people. The functionality of older patients is evaluated using the Barthel Index based on comprehensive geriatric assessment. One of the most common geriatric syndromes is visual impairment. However, there is still no consensus on the role of vision pathology in the development of frailty.

OBJECTIVE. To assess the relationship between the function of the visual organ and the preservation of functionality according to the Barthel scale among older people.

MATERIALS AND METHODS. The article investigates the ophthalmic status of older people (n = 481) aged 75 and older, who were hospitalized for frailty in a geriatric hospital. The study assessed visual acuity using the Sivtsev — Golovin table and confirmed ophthalmological diagnoses. Older participants were categorized based on their level of functionality: severe loss (Barthel index less than 60) and preserved functionality (Barthel index 60 and above). Statistical analysis was conducted using logistic regression to determine the presence of any relationships

RESULTS. The study examined the relationship between patients' sex and age with visual acuity, leading ophthalmological diagnoses, and their connection to functionality (according to the Barthel index). The results showed significant associations between impaired functionality and cataracts (OR = 1.95, 95% CI 1.21–3.12), AMD (OR = 2.64, 95% CI 1.50–4.64), and refractive error (OR = 1.95, 95% CI 1.10–3.49).

CONCLUSION. The presence of multiple eye pathologies increased the likelihood of functionality loss in older patients. The study highlights the importance of implementing organizational solutions for managing older patients with vision problems and suggests a new approach for ophthalmologists to preserve functionality in older patients.

Objective: To comprehensively evaluate the geotechnical conditions of Cerro Kolque-parque in Ayaviri, Puno, it seeks to identify the factors that generate instability and deve-lop viable solutions to mitigate risks associated with landslides that compromise both the safety of infrastructures and that of nearby communities. Methods: A comprehensive methodological approach based on a non-experimental description was used, with the application of several techniques that included geotechnical mapping, the execution of experimental tests such as the Tilt Test (to determine basic friction angles), point load (for mechanical classifications) and uniaxial compression (to evaluate the strength of the mas-sif). In addition, computational tools such as Dips, Swedge and RocData were implemen-ted, which allowed modeling structural conditions and simulating critical scenarios. Re-sults: Areas with a probability of failure greater than 70% stand out, mainly in sectors that present steep slopes combined with significant structural discontinuities. Experimental tests indicated that the basic friction angle values range from 36° to 38°, while the safety factor obtained through Swedge showed critical values (FS < 1) in more than 70% of the Sets analyzed. Conclusion: To guarantee the stability and safety of the area, it is essential to implement structural measures such as support and drainage sys-tems, as well as continuous monitoring programs that ensure the sustainability of the mas-sif in the medium and long term

O texto analisa a formação de professores e o ensino de matemática sob a perspectiva do materialismo histórico-dialético, destacando contradições no sistema educacional e suas implicações na prática docente. Explora a relação entre estrutura e superestrutura, mostrando como práticas pedagógicas refletem e reproduzem desigualdades sociais, mas também têm potencial transformador. Propõe-se superar o modelo tecnicista predominante, centrado na reprodução de conteúdos descontextualizados, em direção a um projeto político-pedagógico crítico e emancipador. A pesquisa, de abordagem qualitativa bibliográfica, analisa as condições materiais e culturais que moldam a formação docente e o ensino de matemática, conectando-os às demandas sociais e econômicas contemporâneas. Os resultados apontam que o paradigma tecnicista permanece nos currículos, priorizando uma abordagem instrumental orientada ao mercado, desconsiderando as necessidades sociais dos estudantes e a possibilidade de uma educação crítica. Soma-se a isso a precariedade do sistema educacional, que dificulta práticas pedagógicas transformadoras. Superar essas limitações exige reformular currículos de formação docente e práticas pedagógicas, integrando teoria e prática, contextualizando o conhecimento matemático e adotando avaliações formativas. Defende-se uma formação que qualifique o professor como mediador e intelectual orgânico, capaz de transformar a sala de aula em espaço de resistência e emancipação. Assim, o ensino de matemática supera o tecnicismo e torna-se uma prática crítica e socialmente comprometida, contribuindo para uma sociedade mais justa e igualitária.

Strength Characteristics of Geopolymer Mortar Formulated with Fly Ash and Ground Granulated Blast Furnace Slag Activated using Wood Ash Lye
Authors: Tan Ying Yi , Awang Hanizam , Mohd Kaus Noor Haida
Published: January 2025

Geopolymer concrete is being introduced as an alternative to conventional concrete to mitigate the consumption of ordinary Portland cement, which emits significant carbon dioxide (CO2) during production. The geopolymer concrete requires alkali activators, such as sodium hydroxide (NaOH) and sodium silicate (Na2SiO3), to enhance the geopolymerisation process. However, industrial alkali activators are costly and environmentally destructive. In this research, the properties of a geopolymer mortar based on fly ash (FA) and ground granulate blast furnace slag (GGBS) were investigated by utilising lye leached from wood ash (WA lye) as a replacement for NaOH. Various FA:GGBS ratios ranging from 0 to 60% were examined to assess the physical and mechanical properties of the mortar. A constant liquid-to-binder ratio and alkaline activator ratio of 0.5 and 3.5, respectively, were maintained for the mix design. The samples were cured at ambient temperature and tested at 3, 7, 14, 28 and 56 days. The results indicate that the compressive strength of the FA-to-GGBS geopolymer mortar increases with increasing GGBS content, with the 60:40 FA:GGBS ratio reaching a peak strength of 35 MPa at 56 days. However, an excessive GGBS content led to a decreased strength of the mortar. Despite this scenario, the flexural strength also increased with increasing GGBS content, reaching 5.11 MPa at 56 days. Additionally, the water absorption of the 60:40 FA:GGBS mixture was the lowest, at 4.73%, with a porosity of 10.41%, indicating a dense and compact microstructure with limited porosity in the mortar. The study suggested that WA lye possesses the potential to replace NaOH in the geopolymerisation process, with the optimal design utilising a FA:GGBS ratio of 60:40. This novel approach not only addresses the environmental and cost issues associated with traditional alkali activators but also contributes to the development of sustainable construction materials. The expertise demonstrated in this research underscores the potential for innovative solutions within the field of sustainable construction technologies.

Published: January 2025

Modern society's growing concern for sustainability is evident in efforts to combat environmental issues like waste accumulation and resource depletion. Recycling waste materials, such as tires and seashells, into sustainable concrete aggregates is crucial for addressing these challenges. However, integrating rubber scraps into concrete can weaken its mechanical properties, with the thickness of the interface between rubbers and cement matrix increasing with higher rubber content. Researchers are exploring ways to mitigate this strength loss by incorporating additional components into rubberized cementitious materials. Similarly, seashell waste presents challenges like soil solidification and illegal dumping, further highlighting the need for innovative solutions in waste management and construction practices. This study investigates the viability of using rubber powder (at 1%, 5%, 10%, and 15%) and clamshell powder (at 5%) as partial substitutes for sand and cement in concrete. Objectives include evaluating concrete’s mechanical properties and determining the optimal rubber powder percentage in combination with clamshell powder. Concrete proportions are meticulously calculated according to mixed design, and materials are mixed in a laboratory concrete mixer. Concrete’s fresh density was determined before pouring into cube moulds with size 100mm x 100mm x 100 mm and prism moulds with size 100mm x 100mm x 500 mm for curing. Samples are cured for 7, 14, and 28 days in water, and then subjected to compression and flexural tests. Results indicate a decrease in compression strength with higher rubber powder percentages, with 15% exhibiting the lowest compression strength (25.06 MPa) and 1% the highest (39.02 MPa). Flexural testing revealed that a combination of 1% rubber powder with clamshell powder yielded optimal results (4.97MPa). In conclusion, the study suggests that the ideal proportion of rubber with 5% clamshell powder is 1%, offering insights into sustainable construction practices.
A Review of Alkali-Activated Soil Reinforcement using Synthetic and Natural Fibers

Published: January 2025

One well-known technique for treating problematic soils is soil stabilization. Its quick and inexpensive deployment provide it an advantage over replacing soil. The chemical stabilization of soil using an alkali-activated binder is referred to as a method to enhance the engineering properties of soil. Alkali-activated binders often have a high peak compressive strength, but they also have a propensity for post-peak brittleness, which is crucial in geotechnical applications. It is understood that shear stress, which is produced when relatively high tensile strength discrete fibers reinforcement are implanted in a treated soil matrix, is transferred to the fibers as tensile strength, increasing the overall soil strength and accelerating the transition from brittle to ductile post-peak behavior. Two different types of fibers—natural and synthetic—are typically used to enhance soil. The major goal of this work is to review, with reference to existing scientific data, the history, advantages, and uses of using various kinds of natural and/or synthetic fibers in alkali-activated soil reinforcement.

Published: January 2025

This paper considers multiple inclined edge cracks under normal stress originating at the interface of two bonded half-planes. The crack problem is formulated into the singular integral equation (SIE) using a modified complex potential (MCP) with the conditions of continuity for traction and displacement. A semi-open quadrature approach is applied for the numerical solution of the SIE. The behavior of stress intensity factors (SIFs) for both Modes I and II at all crack tips is computed and demonstrated graphically. The crack configuration, the elastic constant ratios of the planes, the inclination angle, and the distance between cracks have significantly influenced Modes I and II SIFs. By analyzing the behavior of SIF near the crack tip, engineers may predict the lifespan of the building structures.

El análisis de componentes principales explica las alteraciones en las medidas de formación foliar y acumulación de masa seca con cargas mayores a 75 frutos por rama. Por otro lado, por planta se registraron en promedio 174,92 cm en altura, 39 ramas productivas y 1.337 frutos. Estos resultados indican que hay una correlación negativa entre cargas mayores a 75 frutos por rama con el crecimiento vegetativo; de igual forma, fueron identificados rasgos fenotípicos compartidos y propios de la población evaluada, lo que resalta la utilidad del análisis multivariado para los estudios de diversidad genética de las variedades de café desarrolladas en Colombia.

A core sample of 59 unobscured type 1 active galactic nuclei (AGNs) with simultaneous XMM-Newton X-ray and UV observations is compiled from the archives to probe the nature of soft X-ray excess (SE). In the first paper of this series, our focus centers on scrutinizing the spectral profile of the soft excess. Of the sources, ≈71% (42/59) exhibit power-law-like (po-like) soft excess, while ≈29% (17/59) exhibit blackbody-like (bb-like) soft excess. We show that a cutoff power law could uniformly characterize both types of soft excesses, with a median E
cut of 1.40 keV for po-like and 0.14 keV for bb-like. For the first time, we report a robust and quantitative correlation between the SE profile and SE strength (the ratio of SE luminosity to that of the primary power-law continuum in 0.5–2.0 keV), indicating that stronger soft excess is more likely to be po-like, or effectively has a higher E
cut. This correlation cannot be explained by ionized disk reflection alone, which produces mostly bb-like soft excess (E
cut ~ 0.1 keV) as revealed by relxilllp simulation. Remarkably, we show with simulations that a toy hybrid scenario, where both ionized disk reflection (relxilllp, with all reflection parameters fixed at default values except for ionization of the disk) and warm corona (compTT, with temperature fixed at 1 keV) contribute to the observed soft excess, can successfully reproduce the observed correlation. This highlights the ubiquitous hybrid nature of the SE in AGNs, and underscores the importance of considering both components while fitting the spectra of soft excess.
Potabilizando el agua en Chile: cloración y filtración durante los años 1910-1940
Authors: Llorca-Jaña Manuel , Rivas Rodríguez Javier Eduardo
Published: January 2025

El artículo describe, por primera vez, la naturaleza y temporalidad de la introducción de la filtración y la cloración de agua para consumo humano en Chile. Ambos fueron procesos indispensables para asegurar la potabilidad del agua entregada por cañerías a la población, así como en la batalla para evitar altas tasas de mortalidad general e infantil. Entre mediados de los años 1920 e inicios de los 1930, el estado chileno aseguró la cloración casi universal del agua entregada por cañerías, mientras que las obras de filtración ocuparon un periodo más largo, principalmente durante la primera mitad del siglo XX. Nuestra nueva evidencia muestra que la tasa de mortalidad de enfermedades asociadas a la ingesta de agua no potable, como la fiebre tifoidea y la disentería cayó dramáticamente cuando se comenzó a filtrar y clorar el agua en Chile, salvo en zonas rurales excluidas de la provisión de agua por cañerías.
L’histoire de l’art engagée : Linda Nochlin
Authors: Oléron Evans Émilie
Published: January 2025

Si aujourd’hui, on parle d’histoire de l’art au féminin, c’est grâce à Linda Nochlin (1931-2017), dont l’essai intitulé Pourquoi n’y a-t-il pas eu de grands artistes femmes ?, a fait grand bruit à sa parution, en 1971. Le présent ouvrage retrace la vie et le parcours intellectuel de cette historienne de l’art américaine en articulant histoire de l’art et études de genre. À travers une relecture de ses travaux, dont de nombreux inédits en français, il positionne le féminisme de Nochlin au sein d’autres formes d’engagement. Il montre que son œuvre peut être lue comme un engagement enthousiaste et constant pour la cause de groupes marginalisés, à l’écoute desquelles l’historienne de l’art a passé sa carrière, sous le double signe de l’ouverture et du dialogue. Il démontre que l’engagement a non seulement été un principe fondateur et un moteur des recherches de Nochlin, mais aussi qu’il a constitué une force libératrice qui lui a permis de révolutionner sa discipline.
Il saggio Della condizione della donna di Cristina Trivulzio di Belgiojoso
Authors: Tatti Silvia
Published: January 2025

Écrit pour inaugurer le premier numéro de la prestigieuse revue Nuova Antologia en 1866, l’essai de Cristina di Belgiojoso, Della condizione della donna, présente de nombreux points communs avec des écrits similaires de femmes écrivains et éducatrices de l’époque : avant tout, il prône la nécessité de fournir à toutes les filles une éducation, indispensable pour leur permettre de faire des choix et d’affronter la vie avec dignité, tout en restant dans le cadre d’une vision conservatrice des rôles sociaux et conforme à la morale traditionnelle. Pourtant, l’écriture d’une intellectuelle non-conformiste et militante comme Cristina introduit également des nouveautés importantes dans le débat, comme la revendication du bonheur des femmes, l’appel à une véritable équité éducative qui n’exclut pas les femmes, même si elles sont destinées à être épouses et mères, de toutes les sphères de connaissance, et la constatation, enfin, qu’il n’y aura pas de véritable progrès social et politique sans un profond processus de changement dans la vie des femmes. Tous ces éléments font de cet écrit l’une des interventions les plus significatives et lucides sur la condition des femmes dans les années de construction de l’Italie unifiée.
Appropriation et artificialisation des basses plaines littorales au Moyen Âge en Languedoc. La tourbière littorale de la Palus Nord à Marsillargues
Authors: Leal Émilie , Jorda Christophe , Martin Sophie
Published: January 2025

Le site de la Palus Nord est localisé dans l’Hérault, à la jonction du système lagunaire de l’étang de l’Or et de la plaine deltaïque du Vidourle. Un diagnostic archéologique y a été mené sur près de 45 ha. Jusqu’à 8 m de stratigraphie ont pu être observés, révélant l’évolution de cette zone littorale stratégique tout au long du Moyen Âge. Entre les IXe et XIe siècles, les occupants du site exploitent les ressources offertes par un paysage de tourbière. Après le XIe siècle et de manière brutale, les terres sont asséchées, puis progressivement mises en culture. Ce changement reflète une dynamique de conquête des zones humides, bien connue dans le Bas-Languedoc, qui se met en place au moment où les enjeux économiques d’ordre spéculatif prennent le pas sur l’économie vivrière grâce à un contrôle accru de l’hydrologie et l’extension des terres cultivées.
