Authors: Barrena-Herrán Mikel , Modrego-Monforte Itziar , Grijalba Olatz , Otamendi-Irizar Irati
Published: December 2024

Este artículo presenta una nueva metodología para una clasificación precisa y sistemática del parque edificado a escala municipal. Los métodos desarrollados hasta ahora consideraban variables edificatorias y obtenían resultados genéricos que no son suficientemente detallados para obtener una segmentación que recoge la diversidad del parque residencial de los municipios españoles. La principal aportación de este trabajo es la combinación de dos variables urbanas (densidad-forma urbana y tipología arquitectónica) con las dos variables propias de la edificación que se vienen utilizando más habitualmente (año de construcción y número de plantas). Ello permite desarrollar una clasificación más precisa que hace posible la identificación de cada edificio dentro de su contexto histórico y urbanístico y posibilita una caracterización del parque más detallada. Para su aplicación, se ha creado una herramienta de Sistemas de Información Geográfica (SIG) y se han utilizado software y fuentes de datos de libre acceso. Se ha implementado en el caso de estudio de Donostia-San Sebastián pero es exportable a otros contextos. Los resultados muestran que la metodología propuesta proporciona una clasificación singular y detallada de las tipomorfologías del parque residencial existentes en la ciudad y posibilita un conocimiento profundo de la realidad útil para la toma de decisiones y definición de estrategias y políticas urbanas.

Authors: Flores Matias G. , Phaup Emily , Craigie Heather , Kuronuma Atsuko
Published: December 2024

The field of community engagement in higher education has expanded significantly in the last three decades. Its varied disciplinary perspectives, diverse stakeholders, and wide-ranging cultural contexts have positively contributed to student learning outcomes and community impact. With this expansion comes methodological challenges for doctoral scholars of community engagement, who often lack guidance around conducting community-engaged research that may question traditional epistemologies and ontologies. In this systematic literature review, we analyzed 36 dissertations published between 2018 and 2022 to identify the trends, gaps, and challenges in doctoral research on community engagement. Challenges identified included rethinking research designs, expanding subjects and participants, promoting cross-cultural and global studies, and revisiting epistemological and ontological stances. Recommendations include an open-access dissertation repository, formalized support for graduate students, recognition of “trendbreaking” scholars, and wider embrace of the global network of researchers of community engagement.
Students’ Reflections in an Online Service-Learning (OS-L): An Analysis on Learning Outcomes
Authors: Camarines Teresa M. , Valeriano Elmgay , Balanquit Simon Peter
Published: December 2024

Education plays several important roles, one of which is to promote cognitive development that enriches the social aspects of learners. Service-learning as a pedagogy is reported to develop students’ personal aspects and social engagement. As a teaching tool, students can reflect and better understand their experiences by writing reflections in concluded service-learning activities. However, the unprecedented COVID-19 pandemic posed a challenge in accomplishing course deliverables that required educators to redesign learning delivery and how service-learning pedagogy can be facilitated virtually. Following Kolb’s experiential learning theory, the researchers utilized the rubric that assesses the academic service-learning (AS-L) of gathered reflection papers of Grade 12. This study aims to explore how their online experiences can contribute to a positive learning outcome using the following dimensions: (a) awareness of the purpose of service, (b) critical thinking, (c) application of the AS-L experience to the academic knowledge base and objectives of the course, (d) responsibility to the community, and (e) impact on student’s personal life. These were analyzed using reflexive thematic analysis with computer-assisted data analysis software MAX Qualitative Data Analysis. Given that service-learning plays a vital role in the academic milieu, the outcomes of this study may be used as a benchmark in the sphere of Philippine education and how it can contribute to enhancing students’ reflective process.

Published: December 2024

This study investigated the impact of the service-learning PLACE model on the social and civic competencies, and motivation and engagement in secondary school students. The methodological design was quasi-experimental with a nonequivalent control group. With the data collected from 232 secondary school students from five European countries, the following hypothesis was tested: students who engage in service-learning will have more developed social and civic competencies, higher motivation and engagement in school, and a lower tendency to drop out. Before and after the intervention, the measurement showed statistically significant differences between the groups in several traits and attributes related to social competency measures, social responsibility, personal values, academic perseverance, learning mindset, and overall student engagement and motivation. The results confirmed that service-learning can work effectively on social and civic competencies, to prevent social exclusion risks.
Service Learning in the First Year: Enhanced Retention and Graduation Rates for First-Year and Transfer Students from Underrepresented Groups
Authors: Wyels Cynthia , Martinez Marco V.
Published: December 2024

This study constitutes an assessment of the service-learning program at a minority-serving institution, using data spanning nine years. It focuses on two student populations: those who enrolled as first-time students and the larger population of students who transferred from other institutions, primarily two-year colleges. Within these groups, we examine the effects of service-learning in the first year on Latinx/Hispanic students, low-income students, and other underrepresented student subpopulations on first-year retention and on graduation rates. Using propensity score analysis with full matching techniques means this study may be considered a quasi-experimental design in the cases for which strong balance is obtained. Results indicate that service-learning increases first-year retention rates and increases two types of graduation rates in each case demonstrating strong balance and significance. Results for Hispanic students are particularly notable.

Authors: Mtengwane Gcina
Published: December 2024

South Africa has one of the highest unemployment rates in the world. This unemployment is more pronounced for those living in rural areas. As a result, many unemployed rural people turn to informal trading as a gateway to employment and economic activity. The study aims to explore the experiences and challenges of digital transformation in the informal business sector in a rural South African town. A case study design was used. Data was collected through interviews with a sample of 20 purposefully selected informal traders. The data was then analysed thematically. The study revealed that there is a lack of knowledge on digital transformation among formal traders. The study further revealed that the challenges concerning digital technology include a lack of ICT skills, network and internet connectivity problems, mistrust of technology, and fear of fraudulent activity. The study recommends greater expansion of digital technology support and training to informal traders. This study further recommends that digital technologies must be developed with the end user in mind. Moreover, the study recommends greater internet and connectivity investment in rural areas. Lastly, the study recommends the development of greater security features for digital technologies aimed at informal traders with low literacy levels. The study contributes to knowledge on the benefits and enhancement of the potential of digital technologies to assist small businesses against the background of high unemployment in the rural town of Mthatha, Eastern Cape Province, South Africa.
BOARD ATTRIBUTES AND ENVIRONMENTAL SUSTAINABILITY REPORTING: THE INFLUENCE OF OWNERSHIP STRUCTURE
Authors: Blay Marshall Wellington , Hoeyi Prosper Kweku , Badu Ebenezer Agyemang
Published: December 2024

This study aims to investigate the influence of ownership structure on the extent to which the board attributes in Sub-Saharan Africa (SSA) promote environmental Sustainability Reporting. Using the dynamic panel-data estimation method, the paper uses 1,970 firm-year observations manually extracted from publicly listed non-financial firms' financial reports in SSA from 2012 to 2021. The paper finds that the block ownership structure does not significantly moderate board attributes and environmental sustainability reporting in publicly listed SSA forms.  Also, Government-owned firms moderate board independence and environmental sustainability reporting. The paper further finds that foreign ownership structure influences the relationship between board gender diversity and environmental sustainability reporting in SSA. The paper finds that the relationship between board attributes and ecological sustainability reporting differs and depends on the ownership structure type. These findings imply that corporate governance reforms in the ownership structure should be implemented to improve environmental reporting in SSA.  To strengthen sustainability reporting, policymakers in SSA should prioritize the development of robust regulatory frameworks and consider the nature of ownership structure since the influence of corporate governance characteristics depends on the type of ownership structure. The paper presents a new perspective on board attributes and environmental sustainability literature by uncovering the influence of ownership structure on board attributes and environmental sustainability reporting in SSA. The paper contributes to board attributes and environmental sustainability literature and holds significant theoretical, conceptual, and practical implications.

Published: December 2024

El lupus eritematoso sistémico (LES) es una enfermedad autoinmune crónica, caracterizada por una respuesta inmunitaria anómala que afecta diversos órganos y sistemas del cuerpo, siendo más prevalente en mujeres durante su etapa fértil. Esta enfermedad puede complicar significativamente el embarazo, con riesgos para la salud materna y fetal, incluyendo condiciones graves como taponamiento cardíaco, neumonitis, preeclampsia, trombosis, e incluso muerte fetal. Estas complicaciones son parte de la razón por la cual el diagnóstico y manejo del LES durante el embarazo representan un desafío considerable, ya que las manifestaciones de la enfermedad pueden imitar o confundirse con otras patologías asociadas al embarazo. Sin embargo, los avances en el tratamiento han permitido un mejor control de la enfermedad, con el uso de glucocorticoides, inmunosupresores y anticoagulantes que contribuyen a la estabilización de la condición materna, logrando en algunos casos partos prematuros exitosos y la mejora de la salud fetal. El diagnóstico temprano, junto con un manejo adecuado y oportuno, son esenciales para reducir las tasas de morbilidad y mortalidad en mujeres embarazadas con LES, minimizando los riesgos tanto para la madre como para el recién nacido. Por este motivo, el artículo de revisión en cuestión abordará en detalle los nuevos avances, los cambios recientes y las recomendaciones más actualizadas sobre el manejo del lupus eritematoso sistémico durante el embarazo, con el objetivo de ofrecer a los profesionales de la salud información relevante y actualizada para mejorar los resultados en estas pacientes.

Antecedentes: La enfermedad cardiaca es la principal causa de muerte en Estados Unidos. Uno de los procedimientos invasivos no quirúrgico cuyo objetivo es aliviar el estrechamiento u oclusión de la arteria coronaria y mejorar el suministro de sangre al tejido isquémico es la intervención coronaria percutánea. La cirugía de revascularización coronaria se introdujo en la década de 1960 como el primer procedimiento de revascularización coronaria directa y rápidamente se convirtió en uno de los procedimientos quirúrgicos más comunes en todo el mundo. Esta cirugia sigue siendo el procedimiento quirúrgico cardíaco más común que se realiza y ha sido una de las terapias más estudiadas. Metodología: Se realizó una revisión sistematica a través de diversas bases de datos de Enero de 2014 a Diciembre de 2024; la búsqueda y selección de artículos fue llevada a cabo en revistas indexadas en idioma inglés. Se utilizaron como palabras clave: Epidemiologia, revascularización, coronaria, intervención percutánea. Resultados: La intervención coronaria percutánea (ICP-I) y la cirugía de revascularización coronaria (CRC) han demostrado ser efectivos en la mejora del flujo sanguíneo coronario y la reducción de los síntomas en pacientes con enfermedad coronaria. La ICP-I es más exitosa en pacientes con lesiones menos complejas, mientras que la CRC es preferida para aquellos con enfermedad multivaso o en la arteria coronaria principal izquierda. La ICP-I ofrece una recuperación más rápida y una menor duración de hospitalización, los pacientes sometidos a CRC suelen tener una tasa de éxito a largo plazo superior, especialmente en aquellos con riesgo elevado de eventos cardiovasculares. Conclusiones: Tanto la intervención coronaria izquierda como la cirugía de revascularización coronaria son procedimientos fundamentales. Ambos tratamientos tienen sus ventajas y limitaciones, y la decisión debe ser tomada de manera individualizada, teniendo en cuenta no solo la eficacia, sino también los costos, los riesgos y la calidad de vida de los pacientes a largo plazo.

Background. Methanol is a toxic alcohol that causes severe poisoning due to its metabolites — formic and lactic acid — which lead to metabolic acidosis with a high anion gap and toxic encephalopathy. The severity of clinical features typically manifests within 6 to 72 hours and may include seizures and altered mental status. Case report. We present the case of a 45-year-old patient, a chronic alcoholic with no significant medical history, who was admitted to the Emergency Department in a comatose state (Glasgow Coma Scale [GCS] 4), tachypneic, and following a seizure episode. The patient also had a history of a minor head trauma 24 hours prior. Laboratory results revealed severe metabolic acidosis with a high anion gap, hepatocellular injury, renal insufficiency, and elevated serum levels of amylase and lipase. Toxicology screening, including a urinary sample, ethanol measurement (0 mmol/L), and imaging (MRI), strongly suggested methanol poisoning as the likely diagnosis. The patient was transferred to the Intensive Care Unit, where hemodialysis was performed. Subsequent brain scans revealed typical methanol toxicity patterns, including symmetrical necrosis of the basal ganglia and gliosis of the occipital and optic nerves. These findings underscore the importance of not attributing a low GCS solely to ethanol abuse, highlighting the need for a broader differential diagnosis.

Its technology has hardly changed over the years. Using a simple pulley system, passengers and freight are still lifted steep slopes with minimal energy consumption. This demonstrates the lasting value of simple solutions and engineering intelligence. The article discusses the world’s funiculars and their design characteristics. A correlation analysis for the number of funiculars per country (N) and the country mountainousness index (M) has been carried out. 3 types of regression models have been developed and their determination and correlation coefficients have been calculated. The highest correlation coefficient values are for quadratic and linear mathematical models. The critical values of the correlation coefficients were calculated and compared with the correlation coefficients obtained from the study. For all 36 countries, the correlation coefficient for N and M variables is above the critical value only when a quadratic regression model is used. The correlation coefficients for all models are above the critical value for the 15 economically advanced and tourism-developing countries. The study shows that the number of cable cars in economically developed countries is more strongly correlated with the degree of mountainousness of the country in question.

With the recognition of the impact of the transport sector on climate change and human health, decision-makers are under the pressure to shape the transport sector in a more sustainable way, considering more sustainable options and technologies. Besides that, it is also important to ensure such aspects as affordability, security, reliability and convenience of transport services and the effective functioning of the whole system. Therefore, transport-related policy actions require not only an economic point of view, but also environmental and social actions. The article aims to overview the application of Multi-Criteria Decision-Making (MCDM) techniques for solving sustainability issues in the transport sector and to provide the main insights for methods and sustainability criteria selection. The Search, Appraisal, Synthesis and Analysis (SALSA) framework and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement were applied as the basis for the research. The detailed content analysis of studies is arranged according to the application areas and the methods applied. In order to increase the applicability of the performed analysis and to simplify the decision-making for further studies, the thematic areas for criteria selection are proposed, the most popular MCDM techniques alongside their advantages and disadvantages are briefly discussed.

Fainter standard stars are essential for the calibration of larger telescopes. This work adds to the calibration spectra (CALSPEC) database of 19 faint white dwarfs (WDs) with all-sky coverage and V magnitudes between 16.5 and 18.7. Included for these stars is a new ultraviolet (UV) Hubble Space Telescope (HST) Space Telescope Imaging Spectrograph between 1150 and 3000 Å with a resolution of ∼500. Pure hydrogen WD models are fit to these UV spectra and to six-band HST/Wide Field Camera 3 photometry at 0.28–1.6 μm to construct predicted model spectral energy distributions covering wavelengths from 900 Å to the James Webb Space Telescope limit of 30 μm using well-established CALSPEC procedures for producing flux standards with the goal of 1% accuracy.

Combining Chandra, Atacama Large Millimeter/submillimeter Array, EVLA, and Hubble Space Telescope archival data and newly acquired data from the Apache Point Observatory/Dual Imaging Spectrograph, we detect a double-lobed 17 kpc X-ray emission with plumes oriented approximately perpendicular and parallel to the galactic plane of the massive lenticular galaxy NGC 5084 at 0.3–2.0 keV. We detect a highly inclined (

Three formation scenarios are considered to explain these multiwavelength archival observations: (1) active galactic nuclei (AGN) reorientation caused by accretion of surrounding material, (2) AGN-driven hot gas outflow directed along the galactic minor axis, or (3) a starburst/supernovae driven outflow at the core of the galaxy. This discovery is enabled by new imaging analysis tools including the Selective Amplification of Ultra Noisy Astronomical Signal, demonstrating the abundance of information still to be exploited in the vast and growing astronomical archives.

No X-ray or radio pulsed signal is detected from ROSAT and FAST archive observations. J0606+2132 could evolve into either a Type Ia supernova or an NS through accretion-induced collapse if it is a WD or into an intermediate-mass X-ray binary if it is an NS.
