The coronavirus disease (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has had a profound impact on global health and socio-economic conditions. To date, various vaccines have been administered worldwide in an effort to curb the spread of the virus. Despite vaccination efforts, there have been complications. Existing antiviral drugs have shown limited effectiveness, prompting the use of computational methods to understand the dynamics of the virus and develop suitable treatments. The current study focuses on using biocompatible para-sulfonato-calix[4]arenes to dock against two key proteins of SARS-CoV-2, namely ribonucleic acid (RNA)-dependent RNA polymerase, and helicase. Docking results indicate a strong binding affinity of these compounds to the target proteins, with higher scores compared to commonly used medications. Molecular dynamics (MD) simulation validates the docking results, showing stable protein-ligand complexes over time. The compounds are also screened for absorption, distribution, metabolism, and excretion properties and toxicity, suggesting their potential as lead candidates for inhibiting the virus’s key proteins. However, further in vivo and in vitro studies are recommended to confirm these findings.

What motivates voters to support candidates with backgrounds in public security for Brazil’s National Congress, the so-called Law & Order (L&O) politicians? The 2018 elections witnessed a surge in parliamentarians from police and military backgrounds and the election of a president closely aligned with this agenda. We explore whether this trend correlates with municipal-level violence indicators and the presence of municipal capacity in the security sector, employing various regression models that account for socioeconomic, demographic, political, and geographic factors. Our findings from the additive model reveal a negative association between the level of violence and votes for L&O candidates. This suggests a potential disconnection between fear, victimization, and support for repressive policies, while also indicating that local capacity in the security sector tend to enhance L&O candidates’ performance. However, our model incorporating the interaction between both variables uncovers that violence exacerbates the negative impact on L&O voting when the city has capacity in the security sector. This may reflect a municipal-level preference for preventive measures, particularly in more violent areas, which contrasts with the generally repressive stance of L&O candidates.

Resumen Objetivo: este estudio estima un sistema de demanda de bienes alimenticios en México, incorporando dimensiones territoriales y de ingreso. Se evalúa el impacto diferenciado de choques en los precios en el bienestar económico y la tasa de pobreza, considerando variaciones entre hogares y entre cinco grandes regiones. Metodología: utilizando el modelo de valores unitarios de Deaton (1988) y la Encuesta Nacional de Ingresos y Gastos de los Hogares (ENIGH) de 2018, calculamos elasticidades-precios y elasticidades-ingreso y el impacto de las variaciones de precios en el ingreso y la pobreza. Resultados: revelan importantes diferencias regionales y se subraya la necesidad de considerar diferencias socioeconómicas y regionales y de adoptar un enfoque territorial en este tipo de análisis y para formular políticas efectivas. Limitaciones: existen limitaciones a este estudio que pueden afectar la comprensión completa de la dinámica de la pobreza. Hemos enfocado nuestra atención únicamente en los bienes alimenticios, excluyendo un grupo específico de productos, en este caso, los productos pesqueros. También, se considera que los hogares son únicamente consumidores de bienes, omitiendo así la dimensión productiva de autoconsumo. Originalidad: radica en la vinculación directa entre las estimaciones de pobreza y la desagregación territorial, integra patrones de consumo y elasticidades específicas a cada región. Conclusiones: se resalta la importancia de considerar las diferencias socioeconómicas y regionales al analizar la demanda de bienes alimenticios y su impacto en la pobreza. A pesar de las limitaciones, nuestros hallazgos subrayan la necesidad de un enfoque territorial en este tipo de análisis para formular políticas adaptadas y efectivas de reducción de la pobreza en diferentes regiones del país.

Abstract Objective: this study estimates a system of demand for food products in Mexico, incorporating territorial and income dimensions. The differentiated impact of shocks on prices on economic well-being and the poverty rate is evaluated, considering variations among households and across five major regions. Methodology: using Deaton’s (1988) unit values model and the 2018 National Income and Expenditure Survey (ENIGH), we calculate price and income elasticities, examining the impact of price variations on income and poverty. Results: our results reveal significant regional differences, emphasizing the need to consider socioeconomic and regional variations and to adopt a territorial approach in such analyses for effective policy formulation. Limitations: there are limitations to this study that may affect a complete understanding of poverty dynamics. We have focused our attention solely on food products, excluding a specific group of products, in this case, fishery products. We also assume that households are only consumers of goods, thus omitting the productive and self-consumption dimension. Originality: lies in the direct link between poverty estimates and territorial disaggregation, integrating consumption patterns and specific elasticities for each region. Conclusions: our study highlights the importance of considering socioeconomic and regional differences when analyzing the demand for food products and its impact on poverty. Despite the limitations, our findings underscore the need for a territorial approach in this type of analysis to formulate tailored and effective poverty reduction policies in different regions of the country.

Abstract The study analyzed the technical and environmental feasibility of using Erythrina poeppigiana to produce plywood with different adhesives: phenol-formaldehyde (PF), urea-formaldehyde (UF), and castor oil-based polyurethane (PUA). The physical and mechanical properties of the plywood were evaluated, including apparent density, moisture content, water absorption, thickness swelling, shear resistance, and static bending. Tests proved erythrina’s suitability for non-structural plywood production. The environmental impact of the production process was also evaluated, using embedded energy and CO2e emissions as indicators. The results showed that plywood produced with PU adhesive had better environmental performance compared to panels with FF and UF adhesives. T1 treatment (PF) had the highest embodied energy, while T2 (UF) had the highest CO2e emission. Overall, the study suggests that using erythrina to produce plywood can be a viable option for promoting regional socioeconomic development while also being environmentally sustainable and presents an advantage over foreign plywood in terms of environmental performance. adhesives phenolformaldehyde phenol formaldehyde PF, PF , ureaformaldehyde urea UF, oilbased oil based PUA.

Instructional leadership practices in terms of defining the school mission, managing instructional programmes, and developing a positive school learning climate are significantly and positively associated with teachers' effectiveness. Such practices have also been found to be critical in promoting teacher learning and development both at school and higher education levels. The key question posed in this study was what mathematics teachers' perceptions of their principal's management of the instructional programme of their schools were. The Principal Instructional Management Rating Scale was used as a lens for evaluating teacher perceptions in the study. The study was conducted in two Quintiles 1-3 schools in the town of Kariega, Eastern Cape, South Africa where two secondary school and three primary school teachers participated. The lower socioeconomic status of the two schools under scrutiny seemed to have played a role in the teachers' perceptions of the principals' role as instructional leader. Although the principals conducted and facilitated several professional development sessions with the mathematics teachers, the principal and his assistants were not always familiar with the mathematics pedagogical content knowledge that was required to evaluate lessons at the required level. Factors such as learner discipline, lack of parental support, and socioeconomic problems surrounding the school had an impact on the principals' ability to exercise instructional leadership in their schools.

Abstract The phenomenon of climate change has generated significant adverse consequences on coffee productivity and the income of producers around the world. The present study aims to evaluate the potential repercussions of climate change on coffee production in the Las Montañas region, Veracruz. To carry out this analysis, socioeconomic and environmental data were collected during the years 2022 and 2023, through a survey applied to a sample of 91 production units specialized in coffee cultivation. These data were subjected to ordinary least squares analysis, using the Ricardian approach. The results obtained indicate that the climate change will have a significant impact on the value of the land and that these effects will be differentiated between the different strata of producers, particularly affecting the smaller scale ones. The heterogeneity in climate sensitivity highlights the importance of considering specific strategies for different types of producers in order to reduce their dependence on coffee cultivation and reduce their vulnerability to the increasingly evident impacts of climate change.

Resumen El fenómeno del cambio climático ha generado consecuencias adversas significativas en la productividad del café y en los ingresos de los productores en todo el mundo. El presente estudio tiene como objetivo evaluar las repercusiones potenciales del cambio climático en la producción de café en la región de Las Montañas, del estado de Veracruz. Para llevar a cabo este análisis, se recopilaron datos socioeconómicos y ambientales durante los años 2022 y 2023, mediante una encuesta aplicada a una muestra de 91 unidades de producción especializadas en el cultivo del café. Estos datos se sometieron a un análisis de mínimos cuadrados ordinarios, empleando el enfoque Ricardiano. Los resultados obtenidos indican que el cambio climático tiene impacto significativo sobre el valor de la tierra y que dichas afectaciones son diferenciadas entre los distintos estratos de productores, afectando particularmente a los de menor escala. La heterogeneidad en la sensibilidad al clima destaca la importancia de considerar estrategias específicas para diferentes tipos de productores con el fin de reducir su dependencia respecto al cultivo de café y reducir su vulnerabilidad frente a los impactos del cambio climático.

ABSTRACT Social determinants of health are non-medical factors that have a significant impact on the health of populations. These determinants, ranging from socioeconomic conditions to the physical and social environment, influence access to health care and health outcomes. In this academic text, the theory of social determinants of health, furthermore, the importance of the concept of health equity is highlighted, differentiating it from equality, and the reflection on the positive transition from a biomedical paradigm to one with a holistic approach. Finally, the need to carry out studies of territorial relevance to promote better health in local communities is argued.

RESUMEN Los determinantes sociales de la salud son factores no médicos que tiene un impacto significativo en la salud de las poblaciones. Estos determinantes, que abarcan desde condiciones socioeconómicas hasta el entorno físico y social, influyen en el acceso a la atención médica y en los resultados de salud. En este texto académico, se explora la teoría de los determinantes sociales de la salud, además, se subraya la importancia del concepto de equidad en salud, diferenciándolo de la igualdad, y la reflexión sobre el positivo tránsito de un paradigma biomédico a uno de enfoque holístico. Finalmente, se argumenta la necesidad de realizar estudios de pertinencia territorial para promover una mejor salud en las comunidades locales.

ABSTRACT: Forests require sustainable management because of the long cycle of the species, the balance of the ecosystem, the structure or processes on which the species depend, and socioeconomic development. This study shows the effect of adopting protection measures (non-management and conservation) and their results on the forest structure of a Mixed Ombrophylous Forest, specifically for Araucaria angustifolia available in official publications and scientific articles. Bibliometric analysis was used to obtain and evaluate scientific publications based on their statistical methods, forest inventory techniques, modeling and, which contributed valuable information and scientific impact on the development of the topic. We argue that there are uncertainties about the threat of extinction and that lack of management may increase the disregard for forest resources. Excessive exploitation of the edible seeds of A. angustifolia can destabilize the dynamics and regeneration of the species. The losses of ecosystem services, economic structure, diversity, reproduction, and production of the forest due to non-use of resources are larger than the benefits.The results indicate the need for sustainable forest management as a public policy for the conservation of the species and the Mixed Ombrophilous Forest in southern Brazil.

RESUMEN: Los bosques requieren un manejo sostenible debido al largo ciclo de las especies, por el equilibrio del ecosistema, por la estructura o procesos de los que dependen las especies y por el desarrollo socioeconómico. Este estudio muestra el efecto de la adopción de medidas de protección (no manejado, conservación) y sus resultados para la estructura del Bosque Ombrófilo Mixto, específicamente para Araucaria angustifolia disponibles en publicaciones oficiales y artículos científicos. La metodología utilizada fue el análisis bibliométrico, para obtener y evaluar publicaciones científicas con base en sus métodos estadísticos, técnicas de inventario forestal, modelación y que aportaron información valiosa, impacto científico en el desarrollo del tema. Sostenemos que existen incertidumbres sobre la amenaza de extinción y que la falta de gestión puede aumentar la falta de interés en los recursos forestales. La explotación excesiva de semillas comestibles puede desestabilizar la dinámica y regeneración de la especie A. angustifolia. Las pérdidas ecosistémicas, económicas, de estructura, diversidad, reproducción y producción de las masas forestales por la no utilización de los recursos son mayores que los beneficios. Los resultados indicaron la necesidad del manejo forestal sostenible como política pública para la conservación de la especie y del Bosque Mixto Ombrófilo en el sur de Brasil.

This article investigates the transformative impact of the digital revolution on South African higher education institutions through a Systematic Literature Review. Thus, EBSCOHost, Emerald, Google Scholar, SAGE Journals, ScienceDirect, Springer Link, Elsevier, and Taylor & Francis were used to retrieve and analyse information from scholarly publications such as book chapters, reports, peer-reviewed journal articles, and other publications (n = 17) in South Africa between 2019 and 2023. The research questions of the study aided the discovery of significant themes to explore the transformative impact of the digital revolution on South African higher education institutions. The study found that challenges to embracing digital education in South African higher education institutions include resistance to change, marginalisation of certain socioeconomic groups, poor infrastructure, lack of funding, inadequate Fourth Industrial Revolution tools for instruction, and lack of Fourth Industrial Revolution skills training and development. In contrast, the opportunities include increased student enrolment, Massive Open Online Courses, use of technology to end social exclusion, research and development, and curriculum redesign. The study put forward recommendations that key stakeholders of higher education institutions can use to improve the curriculum in the digital revolution. Prospects for future research were suggested. The study concluded that while various challenges exist for the digital revolution in South African higher education institutions, opportunities can be explored.

Resumo Introdução: O aborto espontâneo é muito comum e o seu impacto nas famílias, na sociedade e nos serviços de saúde é comprovado, mas subestimado. Este relato de caso pretende realçar a importância do acompanhamento após um aborto espontâneo, no luto, nos sintomas psicológicos associados à perda gestacional e na orientação holística do casal. Descrição do caso: Mulher de 37 anos, natural do Nepal, engravida espontaneamente após múltiplas tentativas sem sucesso. Sofre um aborto espontâneo às 10 semanas de gestação e é avaliada pela sua equipa de família, manifestando sentimentos de tristeza, solidão, ansiedade e medo, e desorientação face aos cuidados necessários. O acompanhamento centrou-se no esclarecimento de dúvidas e mitos, no reconhecimento dos sentimentos do casal, na exploração das formas de expressão do luto na cultura de origem, nos ensinos para estimular mudanças de comportamentos e na capacitação para o planeamento de uma nova gravidez. Comentário: Não existem intervenções farmacológicas eficazes para prevenir o aborto espontâneo; contudo, é uma oportunidade para intervir na adoção de hábitos de vida mais saudáveis. Apesar de frequentes, as consequências psicológicas e a psicopatologia associadas ao aborto espontâneo são muitas vezes esquecidas. A experiência do luto é individual e não se baseia necessariamente na idade gestacional, no nível socioeconómico ou educacional, ou no número de perdas ou de filhos vivos. Lidar com este caso exige à medicina geral e familiar avaliar a gestão do luto e o bem-estar físico e mental, despistando psicopatologia e acompanhando o planeamento de uma gravidez futura, atuando em cuidados transculturais e na dimensão social e familiar de cada um.

Abstract Introduction: Miscarriages are common and their impact on families, societies, and health services are proven, but yet underestimated. This case report intends to highlight the importance of follow-up after a miscarriage, especially concerning grief, psychological symptoms associated with pregnancy loss, and the holistic approach to the couple. Case report: A 37-year-old woman from Nepal becomes pregnant spontaneously after multiple unsuccessful attempts. She suffers a miscarriage at 10 weeks of gestation and she is seen by her family doctor and nurse. She expresses feelings of sadness, loneliness, anxiety and fear, and confusion regarding the follow-up care. The process of care focused on clarifying doubts and myths, recognizing the couple's feelings, exploring ways of expressing grief in their culture, encouraging changes in behavior, and helping to plan a new pregnancy. Discussion: There are no effective pharmacological interventions to prevent miscarriage, despite being an opportunity to promote the adoption of healthier lifestyle habits. Although frequent, the psychological consequences and psychopathology associated with miscarriage are often overlooked. The experience of bereavement is individual and it is not necessarily related to gestational age, socioeconomic or educational background, or the number of losses or living children. Dealing with a case of miscarriage requires family physicians to assess grief management and physical and mental well-being, screening for psychopathology and following the planning of a future pregnancy, acting on cross-cultural care and social and family dimensions of each person.

Resumen: Desde la revolución de 2011, Túnez ha experimentado una fase transformadora caracterizada por modelos emergentes de gobernanza que priorizan las iniciativas de base y la participación comunitaria en los asuntos locales. Esta renovación política, a pesar de sus múltiples desafíos, se ha llevado a cabo en períodos de crisis recurrentes que abarcan los dominios político, socioeconómico y de seguridad. A través de un estudio de caso del municipio de Mhamdia, este artículo tiene como objetivo examinar dos aspectos fundamentales: (1) cómo las comunas pueden abordar el patrimonio construido en presencia de actores nacionales, internacionales, gubernamentales, no gubernamentales, lucrativos y sin fines de lucro, y (2) cómo la gestión del patrimonio puede ser desafiante y llevar en ocasiones a la destrucción de elementos históricos. Este análisis cualitativo, enraizado en la investigación práctica, busca explorar los paradigmas cambiantes y las dinámicas en evolución tanto en prácticas tradicionales como novedosas, arrojando luz sobre su impacto en el patrimonio construido. Los resultados demuestran que, al igual que los actores nacionales, las élites locales también aprovechan el patrimonio construido para fortalecer su legitimidad, aunque a través de medios diferentes.

Abstract: Since the 2011 revolution, Tunisia has undergone a transformative phase characterized by emerging models of governance that prioritize grassroots initiatives and community participation in local affairs. Despite its manifold challenges, this political renewal has unfolded during political, socioeconomic, and security crises. Through a case study of the commune of Mhamdia, this article aims to examine two key aspects: (1) how communes can approach built heritage amidst the presence of national, international, governmental, non-governmental, profit, and non-profit actors, and (2) how heritage management can pose challenges, occasionally leading to the destruction of historical elements. This qualitative analysis, rooted in practitioner research, explores shifting paradigms and evolving dynamics within traditional and novel practices, shedding light on their impact on built heritage. The results demonstrate that, similar to national players, local elites also leverage built heritage to fortify their legitimacy, albeit through different means.

BACKGROUND. Trends data up to 2018 suggest that tobacco smoking was increasing in South Africa (SA), but only limited information is available on the impact of the COVID-19 pandemic on the current pattern of use of tobacco and nicotine products (TNPs). OBJECTIVES. To assess trends in sociodemographic patterns in the use of TNPs and the extent to which sociodemographic factors and non-cigarette tobacco use may explain possible changes in rates of TNP use between 2017/18 and 2021. METHODS. Data from three waves (2017, 2018 and 2021) of the South African Social Attitudes Survey (total N=8 140) were analysed. The sociodemographic correlates of current daily and non-daily use of factory-manufactured cigarettes (FMCs), roll-your-own (RYO) cigarettes, waterpipe/hubbly, electronic cigarettes (ECigs), snuff (a smokeless tobacco) and any combination of FMCs, RYO cigarettes and waterpipe/hubbly ('current smoking') in 2017/18 (pre-pandemic) were compared with those for 2021 (during the pandemic). Chi-square analyses and generalised linear models were used to compare the prevalence of TNP use between the two periods. A Blinda-Oaxaca decomposition analysis was also used to explore the roles of various sociodemographic factors, including any differences in the use of TNPs, that may explain any observed differences in smoking rates between 2017/18 and 2021. RESULTS. Current smoking increased significantly from 22.4% (95% confidence interval (CI) 20.4 - 24.5) in 2017/18 to 27.6% (95% CI 24.3 - 31.1) in 2021 (p=0.009). Smoking of FMCs did not change significantly overall between these two periods (20.1% v. 22.1%; p=0.240), except for a significant increase among those who self-identified as black African and a decrease among those who self-identified as coloured and those currently employed. However, the use of waterpipe/hubbly, ECigs, RYO cigarettes and snuff increased significantly. Women, individuals aged <35 years and black Africans had the largest increase in waterpipe/hubbly and ECig use. A decomposition analysis showed that increased waterpipe/hubbly and RYO use explained 52% and 15%, respectively, of the increase in smoking rates, while lower employment during 2021 compared with 2017/18 explained 15% of the increase in smoking rates during 2021. CONCLUSION. The use of all TNPs continued to increase in SA, particularly among women and unemployed people. These findings have policy and practice implications for addressing socioeconomic disparities in tobacco-related diseases.

ABSTRACT Cultural diversity is the result of a process that is formed within the framework of social, economic and cultural relations. It is essential that university professors are prepared to address the cultural diversity of their students, taking into account the particularities of their national culture and that of other groups of different origins that coexist in the same educational setting. Cultural diversity is a challenge for the educational community and must be considered in the ongoing training of professors at medical universities, fundamentally due to their contexts, socioeconomic environments and health problems, especially chronic non-communicable diseases due to their high prevalence and its impact on the individual and his or her family, influenced by risk factors and social determinants, conditioned by their origins, beliefs, experiences and representations that color current intercultural contexts worldwide.

RESUMEN La diversidad cultural es el resultado de un proceso que se conforma en el marco de las relaciones sociales, económicas y culturales. Se hace imprescindible que los profesores universitarios estén preparados para atender la diversidad cultural de sus estudiantes, teniendo en cuenta las particularidades de su cultura nacional y la de otros grupos de diferentes procedencias que coexisten en un mismo escenario educativo. La diversidad cultural es un reto de la comunidad educativa y debe estar contemplada en la formación permanente de los profesores de las universidades médicas fundamentalmente por sus contextos, los ambientes socioeconómicos y los problemas de salud, sobre todo por las enfermedades crónicas no trasmisibles debido a su alta prevalencia y su repercusión en el individuo y su familia, en los que influyen los factores de riesgo y las determinantes sociales, condicionados por sus orígenes, creencias, vivencias y representaciones que matizan los contextos interculturales actuales a nivel mundial.
