A Study on the Effects of Shared Research Facility Services on User Satisfaction and Intention to Continue Using the Service
Authors:   Academic Society of Global Business Administration, Kim Jae Whan , Kwak Chun Hwan , Ahn Tae Ho
Published: January 2025

This study aims to investigate user satisfaction and intention for continuous use from the perspective of users who share research facilities and equipment, focusing on users of the ZEUS (Research Equipment Utilization Service) portal. The research examines national policies on shared research facilities and equipment, and applies the Information Systems Success Model to assess system quality, service quality, and social benefit quality of ZEUS. It also explores user satisfaction based on the service product quality and service environment quality after reserving and using shared equipment. The results indicate that both service quality and social benefit quality significantly affect perceived usefulness and ease of use, while system quality only influences ease of use. Ease of use positively impacts perceived usefulness, which in turn positively affects user satisfaction, but ease of use does not directly influence satisfaction. Both service product quality and service environment quality significantly affect satisfaction, and satisfaction influences the intention for continuous use. The study's limitations include the inability to analyze service quality in greater detail due to regulated procedures for equipment registration. Future research should use expanded models like the Technology Acceptance Model (TAM) or E-SERVQUAL, and consider regional distribution in sample selection for broader analysis.

Este artigo discute caminhos para mudanças gradativas no Fundo de Financiamento Estudantil (Fies) com o objetivo de viabilizar um modelo de financiamento estudantil mais amplo, equitativo, eficaz e eficiente no Brasil. As reformas propostas abrangem três dimensões: i) acesso e matrícula; ii) inadimplência; e iii) fiscalização e remuneração dos agentes financeiros. Em conjunto, as mudanças propostas levariam à fusão do Fies com programas federais de bolsas e subsídios. O novo programa financiaria cursos superiores e de educação profissional e tecnológica, aproveitando isenções fiscais existentes, recursos orçamentários ordinários e a emissão de títulos públicos. Estudantes elegíveis teriam mensalidades pagas pelo governo, a serem reembolsadas se e somente se tivessem renda compatível e em ritmo que não comprometa sua saúde financeira, com a Receita Federal do Brasil (RFB) lhe recolhendo, na fonte, contribuição para essa finalidade.

In this work, we present source-tailored Wide-field Infrared Survey Explorer (WISE) mid-infrared photometry (at 3.4, 4.6, 12, and 23 μm) of 2812 galaxies in the extended Spitzer Survey of Stellar Structure in Galaxies sample, and characterize the mid-infrared colors and dust properties of this legacy nearby galaxy data set. Informed by the relative emission between W3 (12 μm) and W4 (23 μm), we rederive star formation rate (SFR) scaling relations calibrated to L
TIR, which results in improved agreement between the two tracers. By inverse–variance weighting the W3 and W4-derived SFRs, we generate a combined mid-infrared SFR that is a broadly robust measure of star formation activity in dusty, star-forming galaxies in the nearby Universe. In addition, we investigate the use of a W3-derived dust density metric, Σ12 μm (L
⊙/kpc2), to estimate the SFR deficit of low mass, low dust galaxies. This is achieved by combining WISE with existing Galaxy Evolution Explorer ultraviolet (UV) photometry, which we further use to explore the relationship between dust and UV emission as a function of morphology. Finally, we use our derived SFR prescriptions to examine the location of galaxies in the log SFR–log M
stellar plane, as a function of morphological type, which underscores the complexity of dust-derived properties seen in galaxies of progressively earlier type.
Quadrupole Moment of a Magnetically Confined Mountain on an Accreting Neutron Star in General Relativity
Authors: Rossetto Pedro H. B. , Frauendiener Jörg , Melatos Andrew
Published: January 2025

General relativistic corrections are calculated for the quadrupole moment of a magnetically confined mountain on an accreting neutron star. The hydromagnetic structure of the mountain satisfies the general relativistic Grad–Shafranov equation supplemented by the flux-freezing condition of ideal magnetohydrodynamics, as in previous calculations of the magnetic dipole moment. It is found that the ellipticity, and hence the gravitational wave strain, are up to 12% greater than in the analogous Newtonian system. The direct contribution of the magnetic field to the nonaxisymmetric component of the stress-energy tensor is shown to be negligible in accreting systems such as low-mass X-ray binaries.
Performance-portable Binary Neutron Star Mergers with AthenaK

Published: January 2025

We introduce an extension to the AthenaK code for general-relativistic magnetohydrodynamics (GRMHD) in dynamical spacetimes using a 3+1 conservative Eulerian formulation. Like the fixed-spacetime GRMHD solver, we use standard finite-volume methods to evolve the fluid and a constrained-transport scheme to preserve the divergence-free constraint for the magnetic field. We also utilize a first-order flux correction (FOFC) scheme to reduce the need for an artificial atmosphere and optionally enforce a maximum principle to improve robustness. We demonstrate the accuracy of AthenaK using a set of standard tests in flat and curved spacetimes. Using a SANE accretion disk around a Kerr black hole, we compare the new solver to the existing solver for stationary spacetimes using the so-called “HARM-like” formulation. We find that both formulations converge to similar results. We also include the first published binary neutron star (BNS) mergers performed on graphical processing units (GPUs). Thanks to the FOFC scheme, our BNS mergers maintain a relative error of

or better in baryon mass conservation up to collapse. Finally, we perform scaling tests of AthenaK on OLCF Frontier, where we show excellent weak scaling of ≥80% efficiency up to 32,768 GPUs and 74% up to 65,536 GPUs for a GRMHD problem in dynamical spacetimes with six levels of mesh refinement. AthenaK achieves an order-of-magnitude speedup using GPUs compared to CPUs, demonstrating that it is suitable for performing numerical relativity problems on modern exascale resources.

With enough X-ray flux to be detected in a 160 s scan by SRG/eROSITA, the z = 6.19 quasar CFHQS J142952+544717 is, by far, the most luminous X-ray source known at z > 6. We present deep (245 ks) NuSTAR observations of this source; with ∼180 net counts in the combined observations, CFHQS J142952+544717 is the most distant object ever observed by the observatory. Fortuitously, this source was independently observed by Chandra ∼110 days earlier, enabling the identification of two nearby (30″ and 45″ away), fainter X-ray sources. We jointly fit both Chandra and NuSTAR observations—self-consistently including interloper sources—and find that, to greater than 90% confidence, the observed 3–7 keV flux varied by a factor of ∼2.6 during that period, corresponding to approximately two weeks in the quasar rest frame. This brightening is one of the most extreme instances of statistically significant X-ray variability seen in the Epoch of Reionization. We discuss possible scenarios that could produce such rapid change, including X-ray emission from jets too faint at radio frequencies to be observed.
On the Lunar Origin of Near-Earth Asteroid 2024 PT5
Authors: Kareta Theodore , Fuentes-Muñoz Oscar , Moskovitz Nicholas , Farnocchia Davide , Sharkey Benjamin N. L.
Published: January 2025

The near-Earth asteroid (NEA) 2024 PT5 is on an Earth-like orbit that remained in Earth's immediate vicinity for several months at the end of 2024. PT5's orbit is challenging to populate with asteroids originating from the main belt and is more commonly associated with rocket bodies mistakenly identified as natural objects or with debris ejected from impacts on the Moon. We obtained visible and near-infrared reflectance spectra of PT5 with the Lowell Discovery Telescope and NASA Infrared Telescope Facility on 2024 August 16. The combined reflectance spectrum matches lunar samples but does not match any known asteroid types—it is pyroxene-rich, while asteroids of comparable spectral redness are olivine-rich. Moreover, the amount of solar radiation pressure observed on the PT5 trajectory is orders of magnitude lower than what would be expected for an artificial object. We therefore conclude that 2024 PT5 is ejecta from an impact on the Moon, thus making PT5 the second NEA suggested to be sourced from the surface of the Moon. While one object might be an outlier, two suggest that there is an underlying population to be characterized. Long-term predictions of the position of 2024 PT5 are challenging due to the slow Earth encounters characteristic of objects in these orbits. A population of near-Earth objects that are sourced by the Moon would be important to characterize for understanding how impacts work on our nearest neighbor and for identifying the source regions of asteroids and meteorites from this understudied population of objects on very Earth-like orbits.
Predicting the Rate of Fast Radio Bursts in Globular Clusters from Binary Black Hole Observations
Authors: Rao Aryamann , Ye Claire S. , Fishbach Maya
Published: January 2025

The repeating fast radio burst (FRB) source in an old globular cluster (GC) in M81 proves that FRBs, which are typically associated with young magnetars, can also occur in old stellar populations. A potential explanation is super-Chandrasekhar binary white dwarf (BWD) coalescences, which may produce FRB-emitting neutron stars. GCs can also give rise to binary black hole (BBH) mergers detectable with gravitational waves, and the BWD coalescence rate from GCs is correlated with their BBH merger rate. For the first time, we combine independent observations of gravitational waves and FRBs to infer the origins of FRB sources. We use GC formation histories inferred from BBH observations to predict the rate of super-Chandrasekhar BWD coalescences originating from GCs as a function of redshift. We explore mass-loss and mass-conserved scenarios for BWD coalescences and find that the coalescence rates evolve differently across redshift in these two cases. In the mass-loss scenario, the BWD coalescence rates decrease with increasing redshift, similar to some recent measurements of the FRB rate as a function of redshift. We show that GCs could contribute ≲1% to the total FRB source formation rates in the local Universe. Our multimessenger approach also offers a novel method to better constrain the GC population using both FRB and gravitational-wave observations.

Published: January 2025

Purpose

To investigate the effect of art therapy on quality of life and social functioning of individuals with schizophrenia receiving community mental health services.

Method

A quasi-experimental study design was used to assess the effects of art therapy on quality of life and social functioning. The study included 14 participants with schizophrenia, seven assigned to the intervention group and seven to the control group. The intervention group participated in weekly art therapy sessions encompassing various artistic modalities over 16 weeks. Pre- and post-test measurements of quality of life and social functioning scales were administered to both groups.

Results

A significant increase was noted in total scores of quality of life and social functioning scales for the intervention group between pre- and post-test. No significant differences were observed within the control group.

Conclusion

The current study suggests that art therapy promotes quality of life and social functioning of individuals with schizophrenia. Art therapy may be suggested as a psychiatric rehabilitation approach; however, more evidence-based studies are needed for this intervention to be integrated into routine clinical treatment. [

Health Literacy Curricula in Pediatric Residency Programs: A National Survey
Authors: Meyers Nicole , Friedman Suzanne , Morrison Andrea , Costich Marguerite , Gupta Aditi , Moore Brittany , Abrams Mary Ann , Wood Margaret , Solano Joy
Published: January 2025

Objective

Using health literacy informed communication strategies can mitigate health inequities. Despite the high prevalence of limited health literacy among parents and children, pediatricians infrequently use clear communication techniques and further education is imperative. There is minimal literature exploring health literacy curricula in pediatric residencies. We sought to evaluate health literacy education across pediatric residency programs.

Methods

The Academic Pediatric Association's Health Literacy Special Interest Group performed a national, cross-sectional survey of pediatric associate program directors from July 2022 to September 2022. We asked about the presence of health literacy curricula, teaching strategies used, content highlighted, outcomes assessed, and barriers encountered.

Results

Among 55 associate program directors from programs diverse in setting, size, and geographic region who participated, most (84%) reported their residents would benefit from more health literacy training. Only 44% reported the presence of health literacy education, with minimal teaching of evidence-based principles, such as the universal precautions approach to clear communication.

Conclusion

Health literacy is infrequently taught in pediatric residency programs and there is appreciable variability among existing curricula. There is need for greater dissemination of existing resources, as well as standardization of curricula and assessment tools to ensure pediatricians are well-versed in use of health literacy-informed communication techniques.

Case study of potential design perceptions for 3D printed accessories made of used face masks
Authors: Nam Changhyun (Lyon)
Published: January 2025

This study aimed to explore consumer perceptions and acceptance of potential 3D-printed accessories made from used face masks. Based on the principles of the circular economy, a proposed conceptual framework was developed to determine the role of experiential value in the relationship between product design perception and perceived purchase intention. Data were collected through a web-based survey questionnaire, employing a nationwide convenience sample of consumers via crowdsourcing marketplaces. Among the 899 respondents, 470 were female, and 429 were male, with an average age of 38. A structural equation model was used to test the hypotheses in the proposed conceptual framework. The findings indicated that consumer experience plays a crucial role in significantly enhancing purchase intentions for 3D-printed accessories made from used face masks. Participants identified jewelry, electronic cases, and home decor items (e.g., picture frames) as the top three preferred product categories for 3D printing. Usability, social value, and environmental concerns emerged as the most influential components of consumer experience in driving purchase intentions for 3D-printed accessories. Additionally, the study confirmed the mediating role of consumer experience between design perception and purchase intention. These findings provide opportunities to rethink, redesign, and reimagine environmentally responsible, socially inclusive, and economically viable practices. The development of new 3D printing filaments using recycled plastic-based materials further aligned with 3D-printed accessories. Finally, this study offers a critical bridge between academia and industry, paving the way for a sustainable future through innovation in design and manufacturing.
Event-triggered synchronization control for neural networks against DoS attacks
Authors: Liu Yawei , Cui Guangyin , Gao Chen
Published: January 2025

This paper studied the event-triggered synchronization problem for time-delay neural networks under DoS attacks. A novel event-triggered scheme based on switching between periodic sampling and a continuous event-triggered scheme was proposed, which not only cuts down the number of data transmissions but also offsets cyberattacks. By choosing a suitable piecewise Lyapunov-Krasovskii functional and using several free-weighting matrices, sufficient conditions were established to ensure the exponential stability of the synchronization error system in the occurrence of DoS attacks. Furthermore, a co-design method was provided to acquire the desired non-fragile output-feedback control gain and event-triggering parameter. Finally, a numerical example was given to illustrate the usefulness of the proposed approach.
El hilo infinito
Authors: Martin Georges
Published: January 2025

Este libro versa sobre la historiografía regia de los territorios cristianos noroccidentales de la península ibérica (Asturias, León, Castilla y Navarra), así como sobre la de su aledaño “cidiano” entre finales del siglo IX y finales del XII. La perspectiva es fundamentalmente la de una interpretación semántica orientada por el hecho de que hasta muy avanzado el siglo XIII –en concreto, hasta la redacción de las Siete partidas–, la historiografía fue, en la península ibérica, la forma más relevante del discurso político. Pero interpretar la intencionalidad política de una obra participa de una operación global que incluye la determinación de un contexto compositivo, la cual, a su vez, aunque obedezca a métodos e imperativos propios, es indisociable de la cuestión del sentido. La dilucidación genética constituye una dimensión importantísima de este libro, llegando a ser dominante en el caso de la enigmática historiografía dedicada al Campeador. Es asimismo la más polémica, debido a la escasez de datos que brindan las obras de la alta Edad Media sobre las circunstancias de su producción. De ningún modo se pretende ofrecer al lector un panorama interpretativo de la historiografía hispana altomedieval. Al contrario, la obra reúne estudios puntuales y profundizados motivados ora por la relevancia de la propuesta política que brinda una fuente, ora por el interés que ofrece una peculiar dimensión de su sentido, ora por la intensidad de los debates que suscita su composición entre los estudiosos. No por eso carece de una profunda unidad, pues el análisis de cada texto supone la consideración de su contextura con otros, lo que permite apreciar tanto el continuum funcional del saber histórico como la lógica de su constante renovación. Acabado el libro, viene a formar parte del perpetuo entrecruzamiento de creaciones y de lecturas –del hilo infinito– que es y que genera la historiografía medieval.
Analyse sociodémographique de la stratégie de mobilité sociale par la migration et la scolarisation des acteurs populaires haïtiens (1950-2020)
Authors: Dorvilier Fritz
Published: January 2025

Pour les besoins de l’économie postcoloniale, la grande majorité de la population haïtienne a été contrainte d’habiter dans le milieu rural et de cultiver la terre au profit des classes dominantes. Après la levée juridique de cette assignation sociospatiale, l’État haïtien avait continué à priver les paysans d’instruction afin de maintenir leur domination. Cependant, face à la crise agraire survenue environ un siècle et demi plus tard, ils ont vu dans la migration interne et la scolarisation de leurs enfants les moyens les plus appropriés pour changer leurs conditions d’existence et donc occuper une meilleure position dans la société haïtienne. Cet article analyse les dynamiques migratoire et scolaire en Haïti afin de déterminer si elles constituent globalement des facteurs de mobilité sociale.
Étendue, causes et effets de la rareté de main-d’œuvre dans les exploitations agricoles de la commune de la Vallée de Jacmel dans le sud-est d’Haïti
Authors: Daméus Alix , Lespérance Roberson-Joseph
Published: January 2025

Depuis le tremblement de terre de 2010, on assiste à une déperdition de main-d’œuvre dans différents secteurs en Haïti. Ce phénomène a pris une dimension considérable dans la conjoncture sociopolitique et a un effet dévastateur dans le secteur agricole. Cette étude évalue à 20 977 le nombre de travailleurs manquant en 2023 pour l’exploitation normale de toutes les terres agricoles de la commune de la Vallée de Jacmel. Elle détermine, à partir d’un modèle économétrique, les causes internes et externes aux exploitations agricoles de la rareté de main-d’œuvre agricole dans la commune. Elle considère les effets techniques et financiers de cette rareté, avec un regard sur la sécurité alimentaire. Pour déterminer les effets financiers, elle utilise une approche de budget partiel qui évalue s’il y a gain ou perte pour les exploitations agricoles à partir des décisions de changement occasionnées par la rareté de main-d’œuvre. Elle dégage des pistes de solutions pour faire face au problème de rareté de main-d’œuvre agricole dans la commune.
Crise de performance économique et facteurs associés dans les exploitations agricoles en Haïti
Authors: Gabellus Kervline , Joseph Matino , Paul Bénédique
Published: January 2025

Le secteur agricole est au cœur de l’activité économique dans la plupart des pays en développement, jouant un rôle crucial dans leur croissance industrielle et leur transformation structurelle. Il revêt un caractère multidimensionnel dans le développement, touchant à divers aspects tels que la relance économique, la création d’emplois, la contribution aux chaînes de valeur, la réduction de la pauvreté et la garantie de la sécurité alimentaire.En Haïti, l’agriculture emploie environ la moitié de la population active, mais elle est en déclin continu au point de ne représenter qu’environ 17 % de la valeur ajoutée totale du PIB pour l’année 2023. La crise de performance économique des unités de production agricoles se caractérise par des revenus agricoles négatifs au niveau des exploitations agricoles. Une telle crise pourrait représenter une menace pour les investissements et la relance agricole. Ainsi, l’objectif de cette étude a été d’analyser les facteurs associés à la probabilité de revenus négatifs des exploitations agricoles se trouvant dans cette situation de déficit de performance économique. Nous avons utilisé des données secondaires provenant de mille quatre cent trente-quatre exploitations agricoles sélectionnées dans cinq des dix départements géographiques d’Haïti. Une analyse multivariée a été réalisée en utilisant un modèle régression logistique multinomiale pour étudier les facteurs associés à la probabilité d’avoir un revenu négatif.Les résultats du modèle ont révélé six prédicteurs de la probabilité de revenus négatifs au niveau des exploitations agricoles : l’utilisation de la mécanisation agricole, l’impact des événements climatiques (inondation, cyclone), la localisation géographique, la taille du cheptel et l’accès au crédit. En termes de recommandations, nous préconisons d’étendre les services de mécanisation agricole, d’adopter des cultures résilientes aux aléas climatiques, d’utiliser des innovations financières pour améliorer l’accès au financement agricole, de renforcer les services de vulgarisation agricole en intégrant des techniques durables comme l’agroforesterie et la rotation des cultures, et de promouvoir des activités économiques complémentaires telles que l’apiculture, l’artisanat et l’écotourisme pour diversifier les sources de revenus et augmenter la résilience économique des exploitations agricoles. En termes de perspectives, nous suggérons de mener des études sur l’importance du revenu agricole dans le revenu global des exploitants agricoles. De plus, nous proposons de prendre en compte d’autres variables dans l’étude des facteurs associés au revenu agricole, variables que notre étude n’a pas pu considérer, telles que la fluctuation des prix (début de campagne agricole et période de récolte), la taille des pertes agricole et le niveau d’éducation du chef d’exploitation.
Situation socio-économique des exploitations agricoles dirigées par les femmes dans les départements Sud et Artibonite (Haïti)
Authors: Joseph Matino , Gabellus Kervline , Paul Bénédique
Published: January 2025

Dans un contexte marqué par des inégalités de genre persistantes, les femmes jouent un rôle essentiel dans l’agriculture, contribuant de manière significative à la production alimentaire. En Haïti, bien qu’elles participent à toutes les étapes du processus de production, elles restent souvent marginalisées et font face à des contraintes socio-économiques freinant leur potentiel.Cette étude examine les disparités entre les exploitations agricoles dirigées par des femmes et celles dirigées par des hommes, à partir d’un échantillon de 252 exploitations (126 pour chaque genre) situées dans cinq communes des départements du Sud et de l’Artibonite. Ces exploitations, spécialisées dans la production de céréales et légumineuses, ont été analysées à l’aide de statistiques descriptives, de tests du Khi2 et de tests de comparaison de moyennes.Les résultats montrent que les exploitations dirigées par des femmes sont désavantagées en termes de taille, d’accès à l’irrigation, à la mécanisation et aux semences de qualité. De plus, les agricultrices sont moins formées au métier d’agriculteur et bénéficient rarement de projets de développement, ce qui pourrait s’expliquer par des responsabilités domestiques limitant leur disponibilité pour les formations agricoles. Une discrimination dans l’accès aux ressources et aux formations est également plausible, les projets agricoles en Haïti intégrant rarement la dimension genre. En termes de performance socio-économique des exploitations agricoles, aucune différence significative n’a été constatée dans les revenus agricoles et non agricoles moyens ni dans la situation de sécurité alimentaire et nutritionnelle. Pour réduire ces inégalités observées, il est recommandé de renforcer l’accès des femmes aux ressources agricoles clés, comme les semences de qualité et les équipements mécanisés, et de promouvoir leur formation professionnelle dans le secteur agricole.
Une analyse décoloniale et matérialiste des politiques de développement à travers la lecture de Tran Duc Thao
Authors: Lasserre Dimitri
Published: January 2025

Les objectifs de développement durable (ODD) s’inscrivent dans une relation de coopération entre les pays industrialisés et les pays en développement. L’interprétation des politiques coloniales par le philosophe Tran duc Thao peut être éclairante pour saisir les enjeux néocoloniaux à l’œuvre dans ce genre de politique. À travers la lecture de cinq articles de Thao parus entre 1946 et 1949, nous montrerons en quoi les ODD s’ancrent dans une logique de colonialité, au sens décolonial du terme, et placent les petits États insulaires en développement dans un rapport de subordination néocoloniale.
Écologie occidentale et cosmovision andine
Authors: Bourguignon Rougier Claude
Published: January 2025

Adoptant une démarche interculturelle, Alfredo Gomez-Muller nous invite à mieux comprendre les notions andines de Buen Vivir et de Pachamama qu’il met en regard de notre approche écologique occidentale. Il articule ces concepts indigènes comme les deux faces d’une relation respectueuse entre humain, non-humain et cosmos, à l’opposé de l’hubris de la démesure qui menace aujourd’hui la vie sous toutes ses formes.Retraçant certains moments de l’idée de nature et d’écologie dans notre histoire occidentale, l’auteur remonte à l’ethos qui anima la réflexion d’un romantique comme Thoreau au XIXe siècle, et s’intéresse à l’un des versants les plus radicaux de la pensée écologique contemporaine : l’écologie profonde du Norvégien Arne Naess, qui refusait la marchandisation de la « nature » et la réduction de la Vie Bonne à une vie confortable.Pachamama et Buen Vivir sont présentés dans leur lien à l’utopie andine, ce projet indigène de justice sociale inspiré de l’ancien empire inca et né dans la résistance à la domination espagnole. Nous pourrions y voir la manifestation d’une modernité latino-américaine alternative, dans laquelle les réalisations heureuses du passé sont repensées, devenant des réponses aux questionnements cruciaux du présent.
Las ceremonias del verano de Marta Traba: bajo el signo de la errancia
Authors: Ponce Néstor
Published: January 2025

El presente artículo se propone analizar la novela Las ceremonias del verano de Marta Traba, publicada en 1966. La autora es conocida por su trabajo como investigadora del arte latinoamericano, pero mucho menos por su obra de ficción. En esta novela, ambientada en el Buenos Aires de los años 1950, la autora recurre al humor y a la ironía para realizar un retrato de la sociedad argentina de la época. En ese sentido, el uso de estos recursos la acerca a la obra de Jorge Luis Borges, Adolfo Bioy Casares o Julio Cortázar. El concepto de errancia es instrumento fundamental para el análisis, porque permite acercarnos a una poética a través de la temática, del estilo y del carácter autobiográfico del texto.
De lagarta à borboleta: convergências entre literatura, biologia e práticas educativas
Authors: Junqueira de Souza Renata , Martins Gutierres Jessie
Published: January 2025

Este estudo explora a integração entre literatura infantil e ensino de ciências por meio do tema da metamorfose, destacando como as histórias infantis podem promover o ensino de biologia. Analisamos os livros "A primavera da lagarta" de Ruth Rocha e "A lagarta que tomou chá de sumiço" de Milton Célio de Oliveira Filho, que utilizam o ciclo de vida da lagarta até a fase adulta para ensinar conceitos científicos e despertar o interesse pela natureza. A narrativa de Rocha (2011) enfoca a voracidade da lagarta com metáforas poéticas que abordam paciência e empatia, enquanto Oliveira Filho (2007) constrói uma trama de suspense sobre o desaparecimento da lagarta, incentivando o leitor a desvendar o mistério da metamorfose. O estudo aborda o essencialismo psicológico, uma tendência cognitiva natural em crianças de compreender a "essência" das transformações biológicas, como a metamorfose, o que facilita o entendimento intuitivo de processos complexos. Utilizando estratégias metacognitivas, mostramos como o uso de linguagem genérica consolida a metamorfose como uma característica essencial e ajuda as crianças a generalizar este processo a outros contextos. Assim, esses livros da literatura brasileira não apenas cumprem um papel estético, mas também se revelam eficazes para comunicar ciência, ajudando os jovens leitores a entenderem e valorizarem a biodiversidade e o ciclo de vida dos insetos. Ao relacionar o conteúdo literário com práticas de compreensão leitora, este estudo demonstra como a literatura infantil pode promover o gosto estético e uma relação respeitosa com o meio ambiente.
When the cricket sings & the nopal bleeds: (Re)interpreting insect commodification in Oaxaca through anthropological and environmental humanities frameworks
Authors: Pfister Anne E. , Gaytán Cuesta Andrea A.
Published: January 2025

Oaxaca boasts the greatest cultural, linguistic, and biological diversity in Mexico, so insect and human relationships take many forms there. Various insect species are found in iconic specialty foods and the cochineal bug, exported from colonial Oaxaca to dye the world’s textiles and other products, is among the most celebrated. Mexican literature, folklore, art and music celebrate insects, creating various imaginaries surrounding insect-human relationships. For example, Mixtec cosmogonies conceive of insects as spirits of creation and depict them as connections to the land. Today, tourists flock to Oaxaca to sample chapulines and gusanos de maguey or purchase textiles and fibers dyed with natural pigments, including those extracted from cochineal bugs. This paper pairs current ethnographic investigation and comparative literary analysis of contemporary children’s stories, Mixtec cosmogonies, and other media, to examine human-insect imaginaries in Oaxaca, past and present. We use ecocritical frameworks to explore how insects and humans create dialogues that establish a unity of spirits and diversity of bodies, reversing the asymmetrical and exploitative nature of the commodification of insects. We ask how current political economies surrounding the commodification of insects mirror and contradict the political economies of colonial New Spain, and how Indigenous imaginaries dialogue with modern patterns of commodification and exploitation.

Published: January 2025

El amanecer de 1994 en Chiapas, México, dio la bienvenida a la primera rebelión indígena del siglo XXI, una revolución que surgía de la selva ante las políticas extractivistas derivadas del tratado de libre comercio y la globalización. Asimismo, surgió un corpus literario dirigido a niños y jóvenes, en el que un ejército de hormigas y un escarabajo serían los protagonistas del pensamiento del Subcomandante Marcos, portavoz del movimiento. En este ensayo, analizo fragmentos literarios de Don Durito de la Lacandona (1999), En algún lugar de la selva Lacandona (2008) y Aventuras y desventuras de Don Durito (2008), enfocándome en los conceptos de complejidad ambiental y el diálogo de saberes Maya. Planteo que, en sus textos, Marcos reivindica su pedagogía zapatista, reforzando los valores del diálogo humano-no humano, el perspectivismo amerindio y el multinaturalismo, para expandir el pensamiento a los jóvenes y niños zapatistas. Mediante el uso de Selva Lacandona como cuerpo del conflicto y los actores de la lucha zapatista como escarabajos y hormigas, Marcos se presenta como testigo y agente de los eventos, heredando un testimonio histórico de la destrucción de la selva y sus consecuencias.

AI's integration into healthcare promises operational efficiencies. This paradigm shift is driven by the unprecedented growth in data generation, advances in computational power, and sophisticated algorithms capable of learning from vast amounts of data. This approach allows for more precise targeting of therapies, reducing the trial-and-error nature of traditional treatments and improving overall efficacy. In surgical settings, AI is being integrated into robotic systems to enhance precision and control. Robotic-assisted surgeries, guided by AI algorithms, allow for minimally invasive procedures that reduce recovery times and minimize complications. These systems can perform complex tasks with greater dexterity and stability than human hands, improving surgical outcomes and patient safety. Facilitating more efficient information retrieval and analysis, this technology not only saves time for healthcare providers but also improves the accuracy of patient data, leading to better-informed clinical decisions.

This study proposed to synthesize the silver nanoparticle/kappa carrageenan-chitosan (AgNPs/KCar-Chit) hydrogel films and identify the effects of AgNPs on their physical properties and antibacterial performance. The AgNPs/KCar-Chit has been synthesized in 2 stages. The first stage was the synthesis of AgNPs/KCar colloids via the chemical reduction route assisted by microwave irradiation. In the second stage, the silver/kappa carrageenan (AgNPs/KCar) colloid was incorporated with chitosan, and a film was made using the casting technique. The silver nanoparticles formed were validated with a UV-Vis spectrophotometer through the absorption peak at about 400 nm wavelength. FTIR spectra exhibited peaks emerging at the wavenumber 1559.89 cm-1 – 1561.75 cm-1, indicating the formation of the carrageenan-chitosan polyelectrolyte complex. The AgNPs/KCar-Chit hydrogel films had an average solubility of 32%-34%, swelling of 300%-304%, and the surface morphology formed aggregates. The mechanical properties were particularly affected by the incorporation of chitosan. Still, the introduction of AgNPs into the films also influenced the tensile strength, elongation, and elasticity of the AgNPs/KCar-Chit hydrogel film. Further, the greater concentration of AgNPs enhanced the antibacterial performance of the AgNPs/KCar-Chit hydrogel films.

This research investigates the utilization of Escherichia coli and Lapindo mud in a two-chamber Microbial Fuel Cells (MFCs) series. MFCs are tools that convert chemical energy into electrical energy with the help of catalytic reactions from microorganisms. This research uses a dual chamber reactor connected by a salt bridge, with graphite electrodes placed in each chamber and connected by copper cables. Lapindo mud contains heavy metals, such as Cu and Pb. In small amounts, heavy metals required for maintaining various biochemical and physiological functions in living organisms, but in greater amounts they can become hazardous or toxic. Heavy metals are major environmental contaminants. The toxicity of heavy metals is an important issue for ecological, evolutionary, nutritional, and environmental reasons. Lapinda mud was placed in the cathode chamber to produce electricity. The cathode chamber was packed using a mixture of Lapindo mud, ammonium chloride, and sulfuric acid. Various amount Lapindo mud was applied, such as 35, 45, and 55 g. On the anode side, E. coli bacteria was used as microorganisms under anaerobic conditions with glucose as a substrate. E. coli undergoes metabolism, producing NAD+ to transfer electrons to produce electricity. Electrical voltage measurements are carried out periodically every hour for 35 h. The best performance was achieved when 55 g of Lapindo mud was used. The exponential phase of E. coli growth occurred at 10 h of cultivation, resulting in a spike in electricity production of 228.13 mV. After reaching the stationary phase of bacterial growth, the electricity generation remained constant for 19-30 h, which reached 342.9 mV; 0.01 mA, 0.034167 watts.
The impact of pre-hospital emergency medical services on the outcomes of patients with burn: a systematic review and meta-analysis

Published: January 2025

Burn injuries are a worldwide health issue, significantly burdening healthcare facilities. Specialized burn centres are only sometimes available near the site of burn injury. First aid greatly impacted the outcomes of burns by evaluating the severity of the burn and associated injuries. Pre-hospital Emergency Medical Services (EMS) have more remarkable contributions to healthcare systems. We aimed to reveal the interventions provided by the EMS staff on the scene of burn injuries and the impact of these interventions on the outcomes of burn injuries. Furthermore, the study aimed to identify areas for improvement in pre-hospital burn care. A systematic literature review was carried out from inception to 1st July 2023 using twelve databases. All original articles that included patients with burn injuries who received the necessary pre-hospital care by EMS staff were included. Nine articles comprehending 6149 patients with burn injuries were retrieved. The analysis revealed that EMS interventions significantly improved  the outcomes of burn management. This included better control for pain and vital parameters, and lower mortality risk. The EMS provided analgesic administration, cooling of the burn wound, and the necessary urgent therapies.  However, the study identified a need for better EMS training in assessing burn severity and managing burn injuries effectively. Enhancing EMS providers' knowledge and skills in pre-hospital burn management could substantially improve patient outcomes and reduce the burden on healthcare systems. Improving the understanding of EMS providers towards burn care can minimize the risk of burn-related poor outcomes and reduce the burden on healthcare facilities.
Thulaganyo ya seretotumišo (sa Sepedi), pesalema (ya Bibele) le sefela sa kereke (ya Lutere)

The structure of Sepedi traditional praise poem, a psalm (of the Bible) and a hymn (of Lutheran Church). Readers appear to recognise similarities in the structures of hymns, psalms, and ancient praise poems. This article examines whether the proposition is based on facts or truth. Similarity or difference will be realised by contrasting the strata of the three literary texts through the lens of the adapted narratological model. In the content of traditional praise poem, the poet uses the traditional events which are not extracted from his own source. When comparing psalm and hymnal content events, it is clear that they have similarities with traditional praise poem content. This is due to the fact that they are derived from the same source. Traditional praise poet recites the same topic of praising a chief, an animal or a thing, while a psalmist and a hymnist’s topics are related to praising and praying to the Lord and not a chief or a thing. In this manner, a psalmist and a hymnist agree on their structure of the topics, while a traditional praise poet differs with them. A traditional poet praise ancestors and people by paying tribute at the graveyard, whereas a psalmist or hymnist prays to God by giving sacrifices and prayers in church. This helps us understand the differences in how a hymnist, psalmist, and traditional praise poet express reverence to their God or ancestors.Intradisciplinary and/or interdisciplinary implications: This article seeks to examine two fields of study: African literary works and Biblical Study. It draws from scholars of Sepedi traditional praise poetry and sacred songs to re-read the Old Testament texts, in particular Psalms of David focusing on 2 Samuel 22:2–3 and hymnal song taken from Difela tša Kereke, ‘A re godišeng Morena’ by Paul Gerhardt.
Examining the Durability of an Inexpensive Intervention for Improving Point-of-care Ultrasound Documentation Rates

Background:

Point-of-care ultrasound (POCUS) has become a widely used diagnostic tool in emergency departments (EDs), and proper documentation is essential for both patient safety and reimbursement. POCUS is often underdocumented, and therefore, underbilled, by emergency medicine physicians. The absence of POCUS documentation can result in significant revenue loss for both providers and hospital administration.

Methods:

This study is a follow-up study to the manuscript published by Lahham et al. and primarily examines POCUS documentation rates for a 15-month billing period following the initial intervention of a personalized e-mail reminder. Data included rates of documented and phantom scans from three separate 11-day periods (April 2019, July 2019, and July 2020) after the performance feedback intervention in March 2019.

Results:

Documentation rates steadily declined from April 2019 to July 2020 following the intervention, with the highest success rate being immediately after the e-mail intervention.

Conclusion:

This study demonstrates that there is limited durability to a single e-mail reminder as an intervention to improve POCUS documentation in the ED and suggests that there is a need for repeated interventions to prevent deterioration of documentation rates.
