Evaluación de los aprendizajes de estudiantes indígenas: la voz del profesorado
Authors: Meléndez Grijalva Perla , Gill Langarica Oscar Manuel
Published: January 2025

El propósito de este trabajo fue conocer cómo percibe profesorado de primaria la evaluación de los aprendizajes de estudiantes indígenas y de qué manera lleva a cabo este proceso. Es un estudio interpretativo, con método fenomenológico y se aplicó un cuestionario a 64 docentes de la región serrana del estado de Chihuahua, México. En los resultados se identifican dos funciones de la evaluación: conocer el nivel de aprendizajes adquiridos y tomar decisiones para solucionar problemas en el aula y mejorar la propia práctica docente. Las y los participantes priorizan la evaluación diagnóstica y final, sin embargo, la evaluación del proceso se realiza de manera informal y asistemática; asimismo, las evaluaciones informales y semiformales tienen menor peso valorativo que las formales y se apoyan de instrumentos cuantitativos; se encontraron dos posicionamientos, aquellos que evalúan a partir de los indicadores del plan de estudios y quienes lo hacen según las condiciones reales del estudiantado. En ambos casos, hay coincidencia en la preocupación por mejorar las condiciones de su alumnado. Se concluye que, aun cuando persiste un enfoque tradicional en las prácticas pedagógicas, también existe un interés por mejorar la calidad educativa y de vida de estas comunidades indígenas.

Authors: Ramos Mora Dulce María , Escobar López Claudia Angélica
Published: January 2025

Frente a la crisis civilizatoria global, las universidades tienen el compromiso de formar individuos con una conciencia ética y política que contribuya a la transformación socioambiental y a la construcción de sociedades sustentables. Desde hace más de dos décadas, la Universidad Iberoamericana Ciudad de México ha trabajado en la incorporación de la sustentabilidad en su currículo. Esta iniciativa se institucionalizó en los planes de estudio Manresa de 2021, en los cuales la sustentabilidad se incluye como una competencia genérica y un tema transversal. A tres años, el proceso enfrenta desafíos, principalmente la falta de un plan estratégico institucional de ambientalización curricular. Este trabajo describe el recorrido de la Universidad Iberoamericana hacia la transversalización de la sustentabilidad en su currículo, en particular el papel que ha jugado el Programa Universitario para la Sustentabilidad. Discute los logros, las limitaciones y los retos, y plantea acciones para consolidar este proceso en la institución.

Published: January 2025

El objetivo de la presente investigación fue identificar si existe un impacto diferenciado en el acceso y uso de un aplicativo de lectura (Booksmart, de Worldreader) entre estudiantes que utilizaron tabletas comparados con aquellos que utilizaron móvil para acceder al recurso. También se buscó conocer las percepciones de las y los actores involucrados sobre el uso del aplicativo en cada dispositivo. Empleando un diseño mixto concurrente, los datos fueron recolectados el año 2021 mediante llamadas telefónicas a docentes y familias de escuelas públicas periurbanas y rurales del Perú cuando persistía la suspensión de clases debido a la pandemia. Los resultados sugieren que existe un uso diferenciado en favor de aquellos que tenían acceso a tabletas con respecto a los que tenían móviles. Esto se muestra para las variables de conocimiento de y participación en el programa, reportados por los padres. Además, algunos factores que dificultaron el involucramiento en el programa se relacionaron con la baja conectividad y el limitado acompañamiento de familiares y docentes.

Published: January 2025

En los últimos años, el concepto de «responsabilidad social corporativa hacia los empleados» (RSCE) ha adquirido una importancia creciente, tanto en la investigación académica como en la práctica empresarial. Este concepto incluye aquellas políticas de recursos humanos dirigidas a mejorar la satisfacción y bienestar de la plantilla. En este artículo, damos un paso adelante en la investigación sobre la RSCE al examinar su relación con la sostenibilidad medioambiental o innovación ecológica. Además, para arrojar luz sobre la relación entre la RSCE y la sostenibilidad medioambiental, introducimos algunas variables explicativas como el compromiso organizativo y la capacidad de aprendizaje organizativo. Estas relaciones se probaron mediante un modelo de ecuaciones estructurales en una muestra de 300 empresas del sector turístico. Los resultados revelan una relación positiva entre ambas, por lo que la RSCE puede ser entendida como una vía novedosa para incrementar la sostenibilidad medioambiental.
La garantía de «rentas mínimas suficientes» para las personas desempleadas a la luz de la Carta Social Europea: otra asignatura pendiente en un «sistema multinivel»
Authors: Extremera Méndez Francisco Manuel , Martínez Jiménez María Marta
Published: January 2025

El Real Decreto-Ley 2/2024, de 21 de mayo, tras el primer intento fallido, por la falta de la debida convalidación del Real Decreto-Ley 7/2023, de 19 de diciembre, pretendió, y en parte ha logrado, una mejora de la protección social del nivel asistencial en la rama de desempleo. Sin embargo, en su atormentado proceso de elaboración, publicación y vigencia efectiva, estuvo siempre presente una lógica estrictamente interna y de discrecionalidad político-económica, incluso en el marco de un diálogo social fértil. Extramuros quedó, por completo, la dimensión internacional, sobre todo en el ámbito de la Carta Social Europea, que este tema presenta. Pero este nivel de exigencia tutelar y reguladora no se puede obviar, en virtud de la prevalencia que las normas internacionales tienen respecto de las internas, según el artículo 96 de la Constitución española y la Ley 25/2014, de 27 de noviembre, de tratados internacionales. Este estudio identifica las principales razones de disconformidad de la normativa aprobada tras la reforma con la Carta Social, atendiendo a la exigente doctrina jurídica del Comité Europeo de Derechos Sociales, cuyo valor está hoy en el ojo del huracán, por múltiples razones.
Una mirada económica a la protección por desempleo
Authors: Devesa Carpio José Enrique
Published: January 2025

La principal contribución del trabajo es la recopilación de una serie de datos relacionados con las distintas prestaciones generadas por el desempleo. Con ello se consigue una radiografía de la actual situación donde destaca el elevado número de prestaciones, lo cual puede ayudar a dar pistas de las posibles mejoras de actuación.
A partir de los datos recopilados, se pretende, como objetivo principal, clarificar la actual situación de las prestaciones para evitar que se superpongan sus diferentes fines y conseguir de esta forma un sistema más transparente.
La principal conclusión es que debería simplificarse el actual abanico de prestaciones y relacionarlas con el ingreso mínimo vital (IMV), de tal forma que este último resuelva los problemas generados por los escasos ingresos familiares, mientras que las prestaciones por desempleo deberían intentar conseguir la protección de los ingresos mientras se facilita la vuelta al trabajo.
Por ese motivo, se ha creído interesante incluir los últimos datos del IMV, así como clarificar la relevancia que está adquiriendo el elevado crecimiento de los contratos fijos-discontinuos.

Lagunas, disfunciones y antinomias en la protección contributiva por desempleo
Authors: Lasaosa Irigoyen Elena
Published: January 2025

La reforma de la protección por desempleo traída por el Real Decreto-Ley 2/2024 modificó principalmente el nivel asistencial e introdujo pocos cambios significativos en el nivel contributivo. Sin embargo, la ordenación de la prestación contributiva presenta importantes deficiencias, como la exclusión de algunos supuestos del ámbito protector o la obligación en determinadas situaciones de aportar cotizaciones por desempleo que no sirven para generar futuras prestaciones. Además, los requisitos de acceso y las reglas sobre duración y cuantía de las prestaciones generan algunos efectos contradictorios o desproporcionados. En este estudio se analizan las anomalías e insuficiencias del sistema de protección por desempleo contributivo en España, para aportar algunas propuestas al debate sobre su posible reforma.

PROBLEMS AND PROSPECTS OF MUSEUM PEDAGOGY IN MODERN ART EDUCATION
Authors: Bekova G.A , Jou-Yi Chen
Published: January 2025

In the present contribution, we approach museum pedagogy and reflect on its limits and potentials in modern art education to enrich learning through practical involvement with works of art traversed by real-life experiences. Employing a mixed-methods approach, the paper draws on qualitative evidence collected from interviews and focus groups with education professionals alongside quantitative data obtained through surveys to paint a picture of how museum pedagogy is being practiced today, examining current challenges educators are experiencing in doing so, as well as what they may encounter when applying the educational strategy going forward. The key findings from the study are that museum pedagogy is perceived to have a positive impact on critical thinking and cultural awareness, but its adoption in wider education practices is hindered due to limited accessibility, inadequate training of educators, and complex curriculum integration. It also highlights key opportunities for broadening access through digital technology as well as enhancing partnerships between museums and higher education. This research solidifies the argument for focused professional development and systemic transformation to maximize museum pedagogy in the art education setting. We believe that these findings enrich an ongoing background discussion and offer directions for future technical or/and practical developments. This article explains that through addressing the challenges and embracing new opportunities, museum pedagogy will bring a brighter future for arts education, progressing toward more inclusive and creative learning atmospheres.
Southern Ocean control on atmospheric CO2 changes across late Pliocene Marine Isotope Stage M2

Published: January 2025

Abstract. During the Pliocene, atmospheric CO2 concentrations (pCO2) were probably sometimes similar to today's, and global average temperature was ∼3 °C higher than preindustrial. However, the relationships and phasing between variability in climate and pCO2 on orbital timescales are not well understood. Specifically, questions remain about the nature of a lag of pCO2 relative to benthic foraminiferal δ18O in late Pliocene Marine Isotope Stage (MIS) M2 (3300 ka), which was longer than during the Pleistocene. Here, we present a multiproxy paleoceanographic reconstruction of the late Pliocene subtropical–subantarctic zone. New dinoflagellate cyst assemblage data are combined with previously published sea surface temperature reconstructions to reveal past surface conditions, including latitudinal migrations of the subtropical front (STF) over the late Pliocene at Ocean Drilling Program (ODP) Site 1168, offshore of western Tasmania. We observe strong oceanographic variability at the STF over glacial–interglacial timescales, especially the interval (3320–3260 ka) across MIS M2. By providing tight and independent age constraints from benthic foraminiferal δ18O, we find that, much more than benthic δ18O or local SST, latitudinal migrations of the STF are tightly coupled to global pCO2 variations across the M2. Specifically, a northerly position of the STF during the MIS M2 deglaciation coincides with generally low pCO2. We postulate that the Southern Ocean CO2 outgassing varied strongly with migrations of the STF and that this in part accounted for the variability in pCO2 across MIS M2.
Sustainability of regional Antarctic ice sheets under late Eocene seasonal atmospheric conditions
Authors: Vermeulen Dennis H. A. , Baatsen Michiel L. J. , von der Heydt Anna S.
Published: January 2025

Abstract. The Eocene–Oligocene transition (EOT) is marked by a sudden δ18O excursion occurring in two distinct phases approximately 500 kyr apart. These phases signal a shift from the warm middle to late Eocene greenhouse climate to cooler conditions, with global surface air temperatures decreasing by 3–5 °C and the emergence of the first continent-wide Antarctic ice sheet (AIS). While ice sheet modelling suggests that ice sheet growth can be triggered by declining pCO2, it remains unclear how this transition was initiated, particularly the first growth phase that appears to be related to oceanic and atmospheric cooling rather than ice sheet growth. Recent climate model simulations of the late Eocene show improved accuracy but depict climatic conditions that are not conducive to the survival of incipient ice sheets throughout the summer season. This study therefore examines whether it is plausible to develop ice sheets of sufficient scale to trigger the feedback mechanisms required to disrupt the atmospheric regime above the Antarctic continent during warm and moist late Eocene summers and establish more favourable conditions for ice expansion. We aim to assess the sustainability of an incipient AIS under varying radiative, orbital and cryospheric forcing. To do so, we evaluate Community Earth System Model 1.0.5 simulations, using a 38 Ma geographical and topographical reconstruction, considering different radiative and orbital forcings. The climatic conditions prevailing during (and leading up to) the EOT can be characterised as extremely seasonal and monsoon-like, featuring a short yet intense summer period and contrasting cold winters. A narrow convergence zone with moist convection around the region with high sub-cloud equivalent potential temperature exhibits a ring-like structure, advecting moist surface air from the Southern Ocean in both summer and winter. This advection leads to high values of moist static energy and subsequent precipitation in coastal regions. Paradoxically, this atmospheric regime – particularly its coastal precipitation in winter – appears to be necessary for the sustenance of the moderately sized regional ice sheets we imposed on the continent, contrary to our assumption that these ice sheets would disrupt the atmospheric regime. This underscores a hysteresis effect for regional ice sheets on the Antarctic continent, suggesting the potential for a significant volume of ice on the continent without imminent full glaciation prior to the EOT.

Published: January 2025

Abstract. We have performed an extensive statistical investigation of how interplanetary fast forward shocks affect certain turbulence parameters – namely, the normalised cross-helicity (𝜎𝑐), residual energy (𝜎𝑟) and magnetic helicity (𝜎𝑚). A total of 371 shocks detected by Wind at 1 au and seven shocks by Solar Orbiter below 0.5 au have been analysed. We explore how the aforementioned turbulence parameters and their variations across the shock depend on the shock characteristics, i.e. the gas compression ratio, upstream plasma beta, velocity jump and shock angle. We find that in the shock vicinity, fluctuations tend to show outward imbalance (measured by 𝜎𝑐), dominance of magnetic energy (negative 𝜎𝑟) and zero 𝜎𝑚 when averaged over longer periods. The tendency for imbalance and high Alfvénicity (𝜎𝑟 ∼ 0) increases with increasing shock velocity jump, and decreasing upstream beta and shock angle. Shocks with large velocity jumps and gas compression ratio have considerably more balanced (𝜎𝑐 ∼ 0) and less Alfvénic fluctuations in their downstream than upstream, presumably resulting both from Alfvénic fluctuations not passing to the downstream and generation of new compressive fluctuations. We also find that frequency of periods fulfilling the criteria for Alfvén fluctuations (AF) usually decreases, while those meeting the criteria for small-scale flux ropes (SFR) increases from upstream to downstream. The occurrence of AF-like periods peaks for quasi-parallel shocks with large velocity jump, and small upstream beta values. The occurrence of SFR in turn increases with increasing gas compression ratio and upstream beta. The shocks observed by Solar Orbiter at 0.3 – 0.5 au feature overall similar distributions of turbulence parameters and similar upstream-to-downstream changes as detected at 1 au. These results are relevant for understanding turbulence and charged-particle acceleration at collisionless shocks.

Published: January 2025

Abstract. The heterogeneous hydrolysis of dinitrogen pentoxide (N2O5) is a critical process in assessing NOx fate and secondary pollutants (e.g. particulate nitrate) formation. However, accurate quantification of the N2O5 uptake coefficient (γ(N2O5)) in the ambient conditions is a challenging problem which can causes unpredictable uncertainties in the predictions of the air quality models. Here, the γ(N2O5) values were directly measured using an improved aerosol flow tube system in a city located on the plateau in southwestern China to investigate its influencing factors and the performance of current γ(N2O5) parameterization under this typical environmental condition. The nocturnal mean γ(N2O5) value ranged from 0.0018 to 0.12 with an average of 0.023±0.021. The aerosol water significantly promoted N2O5 uptake, while particulate organic and nitrate generally showed suppression effect. We found that median γ(N2O5) predicted by some parameterizations agreed well with observation, whereas the parameterizations failed to reproduce the range of observed values and showed poor correlations (R2=0.00~0.09). Elevated differences between prediction and observation specifically occurred at high aerosol liquid water content (ALWC) with an underestimation by -37 %~-1 % and low ALWC with an overestimation by 34~189 %, respectively. Such differences between the measured and parameterized γ(N2O5) would lead to biased estimation (-77 %~74 %) on particulate nitrate production potential. Our findings suggest the need for more direct field quantifications of γ(N2O5) and the laboratory measurements under extreme ALWC conditions to re-evaluate the response coefficients between γ(N2O5) and aerosol chemical compositions.
The significant role of snow in shaping alpine treeline responses in modelled boreal forests
Authors: Haupt Sarah , Gloy Josias , Farkas Luca , Schildt Katharina , Trimborn Lisa , Kruse Stefan
Published: January 2025

Abstract. Treelines across the Northern Hemisphere are shifting upward and northward in response to global warming, particularly in boreal forests, where climate change progresses more rapidly at high elevations and latitudes. These shifts intensify competition for resources, threaten endemic alpine species, and disrupt established ecological relationships, leading to biodiversity loss. However, significant heterogeneity and regional variation exist in how treelines respond to environmental changes, with many underlying drivers and constraints still poorly understood. This study aims to enhance understanding of alpine treeline dynamics and improve vegetation model predictions under changing climatic conditions. We evaluated the relative impact of key factors influencing treeline migration velocity and examined the effects of varying snow regimes on treeline migration within the alpine treeline ecotone. To achieve this, we incorporated a novel snow module into the vegetation model LAVESI (Larix Vegetation Simulator), enabling the integration of precipitation outside the growing season, snow accumulation, and snowmelt processes. This module allows for explicit modelling of the positive and negative impacts of snow depth on tree growth and treeline migration, while accounting for stochastically occurring extreme events and capturing full weather variability. Our findings reveal site-specific responses to factors driving treeline shifts and forest expansion, with localised conditions playing a critical role in shaping migration dynamics. The Canadian and the Russian sites demonstrate clear insights into primary migration drivers, while the high variability at the Alaskan site indicates more complex local dynamics and greater predictive uncertainty. The study highlights the significant role of snow in modulating migration potential, as snow accumulation creates favourable conditions for seedling germination and growth while also posing risks of increased mortality from snow loads or avalanches. These results underscore the importance of incorporating snow-related processes into vegetation models to improve the accuracy of predictions for boreal forest dynamics. Overall, this study provides valuable insights into tree migration processes, highlighting the varied predictability of treeline responses across regions. These findings carry significant implications for refining vegetation models and guiding conservation strategies to sustain alpine tundra resilience in the face of accelerating climate change.
Orbital-Radar v1.0.0: a tool to transform suborbital radar observations to synthetic EarthCARE cloud radar data

Published: January 2025

Abstract. The Earth Cloud, Aerosol and Radiation Explorer (EarthCARE) satellite developed by the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) launched in May 2024 carries a novel 94 GHz cloud profiling radar (CPR) with Doppler capability. This work describes the open-source instrument simulator Orbital-Radar, which transforms high-resolution radar data from field observations or forward simulations of numerical models to CPR primary measurements and uncertainties. The transformation accounts for sampling geometry and surface effects. We demonstrate Orbital-Radar's ability to provide realistic CPR views of typical cloud and precipitation scenes. The presented case studies show small-scale convection, marine stratus clouds, and Arctic mixed-phase cloud cases. These results provide valuable insights into the capabilities and challenges of the EarthCARE CPR mission and its advantages over the CloudSat CPR. Finally, Orbital-Radar allows for evaluating kilometre-scale numerical weather prediction models with EarthCARE CPR observations. So, Orbital-Radar can generate calibration and validation (Cal/Val) data sets already pre-launch. Nevertheless, an evaluation of synthetic CPR output data to accurate EarthCARE CPR data is missing.
Earthquake swarms frozen in an exhumed hydrothermal system (Bolfin Fault Zone, Chile)
Authors: Masoch Simone , Pennacchioni Giorgio , Fondriest Michele , Gomila Rodrigo , Poli Piero , Cembrano José , Di Toro Giulio
Published: January 2025

Abstract. Earthquake swarms commonly occur in upper-crustal hydrothermal-magmatic systems and activate mesh-like fault networks. How these networks develop through space and time along seismic faults is poorly constrained in the geological record. Here, we describe a spatially dense array of small-displacement (< 1.5 m) epidote-rich fault veins (i.e., hybrid extensional–shear veins) within granitoids, occurring at the intersections of subsidiary faults with the exhumed seismogenic Bolfin Fault Zone (Atacama Fault System, northern Chile). Epidote hybrid extensional–shear veining occurred at 3–7 km depth and 200–300 °C ambient temperature. At a distance of ≤ 1 cm to fault veins, the magmatic quartz of the wall rock shows (i) thin (< 10 µm thick) interlaced deformation lamellae and (ii) systematically crosscutting veinlets healed by quartz and feldspars, and it appears shattered at the vein contact. Clasts of deformed magmatic quartz, with deformation lamellae and healed veinlets, are included in the epidote-rich fault veins. Deformation of the wall-rock quartz is interpreted to record the transient large stress perturbation associated with the propagation of small earthquakes preceding conspicuous epidote mineralization. Conversely, the epidote-rich fault veins record cyclic events of extensional-to-hybrid veining and either aseismic or seismic shearing. The dilation and shearing behavior of the epidote-rich fault veins are interpreted to record the later development of a mature and hydraulically connected fault–fracture system. In this latter stage, the fault–fracture system cyclically ruptured due to fluid pressure fluctuations, possibly correlated with swarm-like earthquake sequences.

Authors: Logroño Alulema Ana , Freire Lascanoa Marcela , Rodriguez Amán Danny , Porras Cabezas Mónica
Published: January 2025

Introducción: El fósforo blanco es una sustancia liposoluble que se absorbe principalmente por el tracto gastrointestinal, tóxico para el ser humano, utilizado para pirotecnia y municiones. Su dosis letal en humanos es de 50-60 mg o de 1 mg por kilogramo de peso, la hepatoxicidad se debe a la generación de radicales libres que lesionan la membrana externa del hepatocito. En el Ecuador no se cuenta con estadística sobre la intoxicación por fósforo blanco. Clínicamente la sintomatología se presenta en cuatro estadios: el primero se caracteriza por síntomas gastrointestinales que evoluciona a daño hepático progresivo asintomático, seguido de clínica de lesión hepática como ictericia y trastorno de la coagulación y por último, el estadio IV se presenta con falla multiorgánica. Presentación de Casos: Se describe dos casos de pacientes de 13 y 15 años con ingesta de “diablillos” (fósforo blanco) como intento autolítico llegando a desarrollar alteración en tiempos de la coagulación y función hepática se catalogan como estadios clínicos II y III; cuyo manejo se basa en N-acetilcisteína, Vitamina k, Lactulosa y especialmente Hemodiálisis y Hemoperfusión. Evolución: A pesar de la evolución rápida a los estadios clínicos en donde se ha evidenciado alto riesgo de morbilidad y mortalidad, con la terapéutica realizada se logra la normalización de la función hepática en aproximadamente 9 días con una recuperación satisfactoria, disminuyendo efectivamente el tiempo de hospitalización y las secuelas en los órganos afectados. Conclusiones: Se considera que la terapia de Hemoperfusión en casos de intoxicación grave por fósforo permite una mejoria clinica evidente, evitando la mortalidad y el daño hepatico permanente.

Terapía pulpar radical con sistemas rotatorios en dentición decidua
Authors: Solano Altamirano Denisse Carolina , Cabrera Alejandra
Published: January 2025

La terapia pulpar es un procedimiento dental destinado a abordar lesiones cariosas profundas. En el caso de pacientes pediátricos con dentición decidua que presenten pulpitis o necrosis pulpar, la opción más recomendada es llevar a cabo una pulpectomía o terapia pulpar radical. A lo largo de los años, este procedimiento se ha realizado manualmente, pero con los avances tecnológicos, ahora es posible llevarlo a cabo utilizando sistemas rotatorios. El propósito de este estudio es describir, a través de la revisión de la literatura, el uso de sistemas rotatorios en comparación con instrumentos manuales en el tratamiento de pulpectomías en dentición decidua. Se han evaluado los ensayos clínicos aleatorizados realizados en los últimos 10 años. La intención es contribuir a un mejor entendimiento de las técnicas de pulpectomía más efectivas y menos traumáticas, especialmente en la población pediátrica. Este análisis busca una visión más completa y actualizada sobre las opciones disponibles, aprovechando los beneficios de las tecnologías modernas para mejorar la eficacia y la comodidad en el tratamiento de pulpectomías en niños con dentición decidua.
Crime rates and justice innovations in the Torres Strait Islands
Authors: Scott John , Staines Zoe , Morton James
Published: January 2025

For decades, Australian criminologists have cited crime statistics to illustrate the extreme disadvantage Indigenous peoples in Australia experience in the criminal justice system. Official statistics often present a bleak picture of Australian Indigenous communities, presented as ‘problems’. However, broad-brush understandings of Indigenous Australians’ interactions with the criminal justice system, as well as sweeping policy responses, often fail to appreciate diversity across and between Australian Indigenous communities. This briefing paper draws on research carried out as part of a Criminology Research Grant through the Australian Institute of Criminology and points to some of the solutions these communities are developing to tackle the historical and contemporary injustices of colonisation and racism.

Sharia Principles In Risk Management In Islamic Banking: A Literature Review
Authors: Haikal Mohammad , Efendi Sumardi , Ramly Arroyyan
Published: January 2025

Islamic banking operates based on sharia principles, which strictly prohibit practices such as riba (interest), gharar (excessive uncertainty), and maysir (gambling). These prohibitions directly influence the approach to risk management. This study aims to review existing literature related to the application of sharia principles in risk management within Islamic banking. To thoroughly explore the topic, this study employed a library research method, which involved collecting, analyzing, and synthesizing information from various academic sources, including scholarly journals, books, and research reports.  The findings reveal that Sharia principles not only provide a unique framework for risk management but also strengthen the financial stability of Islamic banks by avoiding speculative practices and excessive uncertainty. Furthermore, the Sharia Supervisory Board (known as DPS) plays a crucial role in ensuring compliance with these principles. Thus, the application of Sharia principles in risk management significantly contributes to the sustainability and stability of Islamic banking. However, challenges remain, such as the limited availability of Sharia-compliant financial instruments. This study recommends further study to develop innovative and Sharia-compliant risk management instruments and strategies to support the future development of Islamic banking

O Serviço de Nutrição e Dietética (SND) hospitalar deve estar atento à produção de refeições seguras, visto que são destinadas a pacientes com imunidade baixa, mais propensos a desenvolver doenças de origem alimentar. Este estudo teve por objetivo avaliar as boas práticas em dois SND hospitalares, no que se refere à preparação e armazenamento do alimento, higienização de hortifrutícolas e coleta de amostras de alimentos preparados e servidos aos pacientes e funcionários destes locais. Estudo observacional de corte transversal, realizado em cinco dias consecutivos do mês de setembro de 2024, na etapa inicial do estágio curricular obrigatório de Alimentação Institucional do curso de nutrição de uma universidade do Rio Grande do Sul, que envolve a observação do funcionamento do local, realizado por duas estagiárias em dois SND hospitalares de pequeno porte, denominados SND 1 e SND 2 para o presente estudo, localizados na Serra Gaúcha/Rio Grande do Sul. Para a coleta dos dados foram avaliados os seguintes critérios: produtos pré-preparados e preparados, higienização dos hortifrutícolas e coleta de amostras de alimentos preparados constantes na Portaria nº 799, de 06 de setembro de 2023 da Secretaria da Saúde do Estado Rio Grande do Sul. Os resultados mostraram que o SND 1 obteve 90,00% de conformidade em relação aos critérios avaliados. Já o SND 2 um índice de 70,00% de conformidade. Conclui-se que ambos os SNDs demonstraram boas condições higiênico-sanitárias, pois atenderam a maioria dos critérios de inspeção avaliados, sendo que o SND 1 apresentou maior conformidade de adequação à legislação em relação ao SND 2. Este estudo demonstra a importância da aplicação do checklist nos serviços de alimentação, como forma de inspecionar inadequações, as quais devem ser corrigidas para que não comprometam as boas práticas de manipulação de alimentos nesses serviços e possibilitem a oferta de uma alimentação segura aos pacientes e funcionários dos locais.

O Debate das Relações Étnico-Raciais na Disciplina de História no Novo Ensino Médio - (BNCC): algumas problematizações
Authors: Cesar Alves da Mota Marcos
Published: January 2025

Este trabalho tem por objetivo analisar as problematizações envolvendo o ensino de relações étnico-raciais na disciplina de História, conforme orientações da Base Nacional Comum Curricular (BNCC) para o Novo Ensino Médio. O estudo, de natureza teórico-bibliográfica e abordagem qualitativa ao discutir a relevância do tema a partir Frigotto (2023), Mignolo (2020), entre outros ao que tratar da inclusão de conteúdos relacionados à história e cultura afro-brasileira e indígena no currículo escolar, destacando desafios e avanços. A análise evidencia que, apesar das diretrizes da BNCC, as práticas pedagógicas e os materiais didáticos ainda apresentam lacunas significativas. Constatou-se que as iniciativas para garantir a efetiva inserção dessas temáticas na educação pública são esparsas e fragmentadas, dificultando a construção de um ensino de História que contemple, de forma abrangente, as relações étnico-raciais.
Regelungen zur Gesellschaft bürgerlichen Rechts aus der Perspektive der Reform
Authors:   Korean Civil Law Association, Kim Sejun
Published: January 2025

Die externen und internen Beziehungen der Gesellschaft bürgerlichen Rechts (GbR) sollten getrennt geregelt werden. In diesem Zusammenhang können Parteifähigkeit und Grundbuchfähigkeit aus legislativer Sicht befürwortet werden, da es notwendig ist, die externe Stabilität in den Rechtsverhältnissen der GbR zu sichern. Gleichzeitig ist die GbR ein Vertrag, dessen Inhalt von den Parteien frei gestaltet werden können muss. Dementsprechend sollte der Inhalt des Gesellschaftsvertrags auf der Privatautonomie der Parteien basieren, und sobald dadurch die Zugehörigkeit des Gesellschaftsvermögens bestimmt ist, muss diese entsprechend der absoluten Wirkung des dinglichen Rechts geregelt werden. Jedoch unterstützen die derzeitigen §704 und §271(2) des KBGB dieses Regulierungssystem nicht.
Daher schlägt dieser Beitrag eine Änderung des §704 vor, unter der Annahme einer vorherigen Reform des §271. Dieser Änderungsvorschlag sieht das Weggefallen des §271(2) vor, um das Eigentum zur gesamten Hand als zwingende Vorschrift festzulegen, und basiert auf der Voraussetzung, die Gesamthandseigenschaft im §271 ausdrücklich zu benennen. Wenn durch §704 das Gesellschaftsvermögen in das Gesamthandseigentum der Gesellschafter übergeht, können die Parteien dessen Inhalt nicht anderweitig vereinbaren. Es bleibt jedoch den grundlegende Zweck, dass die Parteien des Gesellschaftsvertrags die Eigentumsverhältnisse der Gesellschaft auch anders als im Gesamthandseigentum regeln können.
