See you later: roost fidelity of the "Boomerang Bats",Artibeus lituratus (Olfers, 1818) (Mammalia, Chiroptera) / Até mais tarde: fidelidade de abrigo dos "Morcegos Boomerang", Artibeus lituratus (Olfers, 1818) (Mammalia, Chiroptera)

Animals exhibit sociability behaviors and spatial use patterns that are important for species survival. Bats are animals that exhibit complex patterns of aggregation of individuals, which can vary according to sex and age. Aggregation can be explained by active or passive mechanisms. In this behavioural note, we report a group of female Artibeus lituratus in the reproductive stage that exhibits aggregation behavior supporting the active mechanism hypothesis. The females returned to the same roost, for two reproductive season, maintaining the aggregation with the same individuals with which the social bonds were already established.

Os animais exibem comportamentos de sociabilidade e padrões de uso espacial que são importantes para a sobrevivência das espécies. Os morcegos são animais que apresentam padrões complexos de agregação de indivíduos, que podem variar de acordo com o sexo e a idade. A agregação pode ser explicada por mecanismos ativos ou passivos. Nesta nota comportamental, relatamos um grupo de fêmeas de Artibeus lituratus em fase reprodutiva que exibe comportamento de agregação apoiando a hipótese do mecanismo ativo. As fêmeas retornaram ao mesmo poleiro, por duas estações reprodutivas, mantendo a agregação com os mesmos indivíduos com os quais os laços sociais já foram estabelecidos.

The Experience of Strengthening the Professional Motivation of Pediatricians Abroad and Its Enlightenment to China / 中国医学伦理学

At present, the contradiction between the lack of pediatricians and the increasing demand for pediatric medical services has become more and more prominent. Taking pediatricians as the research object, this paper explored the needs and motivation of professional development of pediatricians in China by referring to a series of excellent foreign research results, so as to improve the professional development of pediatricians, reconstruct the ecology of pediatricians and patients, then improve medical experience, and alleviate the "shortage of pediatricians" and "difficulty in seeing a doctor" in pediatrics. Enhancing the work enthusiasm and professional motivation of pediatricians can not only improve the satisfaction of patients, but also enhance the quality of medical services, so as to promote the growth of the hospital’s own economic and social benefits.

Diversity patterns of vascular and non-vascular epiphytes along tropical dry forest / Patrones de diversidad de epífitas vasculares y no vasculares a lo largo del bosque seco tropical

Abstract Introduction: Epiphytes (vascular and non-vascular) are one of the most diverse groups in the Neotropics, but despite their importance in the functioning of many ecosystems, much of their taxonomy and ecology is still unknown in the dry forest of Colombia. Objective: To compare the diversity patterns and species composition of vascular and non-vascular epiphytes along tropical dry forest remnants of Cauca Valley, Colombia. Methods: Ten permanent plots (50 x 20 m2) were established in tropical dry forest remnants. The epiphytes were sampled in 40-50 trees per plot. Alpha and gamma diversity were calculated using the richness (q0) and Shannon index (q1) (alpha was estimated as the average for phorophytes). Beta diversity was measured using the Whitaker index. To evaluate the relationship between diversities and environmental variables, GLM analysis was used. Results: We found 50 morphospecies of vascular epiphytes, 77 of bryophytes and 290 of lichens. The 𝛼 and 𝛾 diversity of bryophytes from each remnant was significantly explained by temperature. The abundance of lichens per tree was significantly related with the DBH and tree height of each remnant. The 𝛼 diversity of vascular epiphytes shown can be explained by temperature and precipitation. The 𝛾 diversity was strongly influenced by the beta diversity in bryophytes and lichens. This pattern is because the sites with high disturbance present a lower diversity, as a consequence of a homogenizing effect, that is, a low turnover of species between sampling units. Conclusions: Precipitation and temperature affected the diversity of bryophytes and vascular epiphytes, while it did not show a relationship with the lichen's diversity, for which there is not a high congruence between the diversity and composition of these epiphytes.

Resumen Introducción: Los epífitos (vasculares y no vasculares) son uno de los más diversos grupos de plantas en el Neotrópico, pero a pesar de su importancia para el funcionamiento de varios ecosistemas, existen grandes vacíos en su conocimiento taxonómico y ecológico en el bosque seco de Colombia. Objetivo: Comparar los patrones de diversidad y composición de especies de epífitas vasculares y no vasculares a lo largo de remanentes de bosque seco tropical del Valle del Cauca, Colombia. Métodos: Se establecieron diez parcelas permanentes (50 x 20 m2) en remanentes de bosque seco tropical. Las epífitas se muestrearon en 40-50 árboles por parcela. La diversidad alfa y gamma se calculó utilizando la riqueza (q0) y el índice de Shannon (q1) (alfa se estimó como el promedio para los forófitos). La diversidad beta se midió utilizando el índice de Whitaker. Para evaluar la relación entre diversidades y variables ambientales se utilizó el análisis GLM. Resultados: Se encontraron 50 morfoespecies de epífitas vasculares, 77 de briófitas y 290 de líquenes. La diversidad de 𝛼 y 𝛾 de briófitas de cada remanente fue explicada significativamente por la temperatura. La abundancia de líquenes por árbol se relacionó significativamente con el DAP y la altura del árbol de cada remanente. La diversidad 𝛼 de epífitas vasculares que se muestra puede explicarse por la temperatura y la precipitación. La diversidad 𝛾 estuvo fuertemente influenciada por la diversidad beta en briófitas y líquenes. Este patrón se debe a que los sitios con alta perturbación presentan una menor diversidad, como consecuencia de un efecto homogeneizador, es decir, un bajo recambio de especies entre unidades de muestreo. Conclusiones: La precipitación y la temperatura afectaron la diversidad de briófitas y epífitas vasculares, mientras que no mostró relación con la diversidad de líquenes, por lo que no existe una alta congruencia entre la diversidad y composición de estas epífitas.

Ética, ecología y ecosofía: perspectivas divergentes para refundamentar la bioética global

el texto busca ampliar las fronteras del concepto de "bioética global", centro de la propuesta teórica de Van Rensselaer Potter sobre la "bioética ecológica" en su obra Global Bioethics, de cara a la "ética de la tierra" desarrollada por el ecólogo y ambientalista Aldo Leopold y el análisis de la "ecosofía" planteado por el filósofo y psicoanalista Félix Guattari en Las tres ecologías. Dicha caracterización se plantea con el fin de establecer presupuestos teóricos en torno a las nociones de bioética ecológica y ecosofía en la perspectiva de la bioética global en un renovado intento de ampliación de sus horizontes disciplinares. Se establecen tres momentos para el análisis: inicialmente se caracteriza la ética de la tierra propuesta por Arnold Leopold en su obra A Sand County Almanach. Posteriormente, se analizan los principales aspectos de la "ética ecológica" en la obra Global Bioethics. Finalmente, se destacan varios aspectos de la ecosofía de Félix Guattari que ponen en perspectiva el acento ecológico de la bioética global de Potter y que podrían considerarse como presupuestos divergentes útiles para enriquecer la bioética global en la actualidad.

the text seeks to expand the boundaries of the concept of "global bioethics," the core of Van Rensselaer Potter's theoretical proposal on "ecological bioethics" in his work Global Bioethics, in the face of the "ethics of the Earth" developed by the ecologist and environmentalist Aldo Leopold and the analysis of "ecosophy" raised by the philosopher and psychoanalyst Félix Guattari in The Three Ecologies. This characterization is proposed to establish theoretical assumptions around the notions of ecological bioethics and ecosophy from the perspective of global bioethics in a renewed attempt to broaden its disciplinary horizons. Three moments are established for the analysis: initially, the land ethics proposed by Arnold Leopold in his work A Sand County Almanach is characterized. Subsequently, the main aspects of "ecological ethics" in Global Bioethics are analyzed. Finally, several aspects of Félix Guattari's ecosophy are highlighted that put into perspective the ecological accent of Potter's global bioethics, which could be considered valid divergent presuppositions to enrich global bioethics today.

Spatio-temporal variation in the growth of coral fragments of opportunity in the Eastern Tropical Pacific: implications for coral reef restoration

Introduction: Coral-reef communities are considered one of the most biodiverse, but also most threatened, marine ecosystems, and the accelerating loss of habitat over the past decades warrants active intervention. Objective: The present study demonstrates the successful implementation of a low-impact restoration technique in three Central Mexican Pacific degraded coral communities, using a protocol based on natural fragmentation (''fragments of opportunity") of the branching coral Pocillopora spp., considered the most abundant and primary carbonate-producing coral species of the Eastern Tropical Pacific. Methods: The restoration program was implemented in two offshore and one inshore coraline areas. The relationships between seawater temperature and coral survival, growth, and attachment rate were assessed over one year, with 183 fragments monitored each month. Results: The mean coral growth rate was 3.3 ± 0.1 mm mo-1, with annual growth rates in length and width of 39.9 ± 14.2 and 36.5 ± 19.5 mm yr-1, respectively. Self-attachment efficiency was 78 % and the survival rate was high (84 %). The growth rate differed significantly among reefs. Conclusions: Upon monitoring directly fragmented corals over a year, growth rates were deemed high enough to merit active restoration in the region. However, our data show that structural and abiotic differences and seasonal variability must be considered overall in successful long-term coral community restoration initiatives in the eastern Pacific region.

Introducción: Las comunidades de arrecifes de coral se consideran uno de los ecosistemas marinos con mayor biodiversidad, pero también los más amenazados, y la pérdida acelerada de hábitat en las últimas décadas justifica la implementación de una intervención activa. Objetivo: El presente estudio demuestra la implementación exitosa de una técnica de restauración de bajo impacto basada en la fragmentación natural (''fragmentos de oportunidad") del coral ramificado Pocillopora spp., la cual es la especie coralina más abundante y principal productora de carbonato del Pacífico Oriental Tropical. Métodos: El programa de restauración se implementó en dos sitios lejos de la costa y un sitio cercano a la costa, con comunidades coralinas degradadas. Las relaciones entre la temperatura del agua de mar y la supervivencia, el crecimiento y la tasa de adhesión de los corales se evaluaron durante un año con 183 fragmentos monitoreados cada mes. Resultados: La tasa media de crecimiento coralino fue de 3.3 ± 0.1 mm mo-1, con tasas de crecimiento anual en largo y ancho de 39.9 ± 14.2 y 36.5 ± 19.5 mm año-1, respectivamente. La eficiencia de la auto-adherencia fue del 78 % y la tasa de supervivencia fue alta (84 %). La tasa de crecimiento difirió significativamente entre los arrecifes. Conclusiones: Al monitorear directamente los corales fragmentados durante un año, las tasas de crecimiento se consideraron lo suficientemente altas como para merecer una restauración activa en la región. Sin embargo, nuestros datos muestran que las diferencias estructurales y abióticas y la variabilidad estacional deben considerarse en general en las iniciativas exitosas de restauración de comunidades de coral a largo plazo en la región del Pacífico oriental.

Change in the composition of fauna associated with Pocillopora spp. (Scleractinia, Pocilloporidae) following transplantation

Introduction: Associated fauna comprises most of the diversity of a coral reef and performs ecological functions essential to the reef's survival. Since Pocillopora corals harbor an important associated fauna, reef restoration efforts are underway in Golfo Dulce, Costa Rica, to preserve them. Objective: To describe changes in cryptofauna and fish communities associated with Pocillopora colonies to better understand the succession of associated fauna following transplantation. Methods: An experimental patch of 30 nursery-grown Pocillopora colonies and a control patch containing no colonies were monitored for 8 months following transplantation in Golfo Dulce. Cryptofauna within each colony and fish within each patch were observed using SCUBA to quantify temporal changes in the abundance, diversity, and community structure of the colonies. Results: The abundance and diversity of cryptofauna increased throughout the experiment. Obligate symbiont decapods were the most abundant. The composition of the community of cryptofauna differed between periods with fish in the genus Scarus as the main contributor to any differences. The increase in abundance and diversity of cryptofauna and fish may reflect coral growth and the corresponding availability of space and environmental complexity in the experimental patch. The composition of the cryptofauna communities was generally consistent with other studies. However, a high density of decapod symbionts could suggest that without other Pocillopora colonies to move to, they may crowd together despite their aggressive tendencies. Conclusions: Pocillopora colonies will experience an increase in symbionts that could positively contribute to the health and survival of the coral following transplantation.

Introducción: La fauna asociada comprende la mayor parte de la diversidad de un arrecife de coral y realiza funciones ecológicas esenciales para la supervivencia del arrecife. Dado que los corales Pocillopora albergan una importante fauna asociada, se están realizando esfuerzos de restauración de arrecifes en Golfo Dulce, Costa Rica, para preservarlos. Objetivo: Describir los cambios en la comunidad de criptofauna y peces asociados a las colonias de Pocillopora para comprender mejor la sucesión de la fauna asociada después del trasplante. Métodos: Un parche experimental de 30 colonias de Pocillopora cultivadas en vivero y un parche de control que no contenía colonias fueron monitoreados durante 8 meses después del trasplante en Golfo Dulce. La criptofauna dentro de cada colonia y los peces dentro de cada parche se observaron usando SCUBA para cuantificar los cambios temporales en la abundancia, diversidad y estructura de la comunidad de las colonias. Resultados: La abundancia y diversidad de criptofauna aumentó a lo largo del experimento. Los decápodos simbiontes obligados fueron los más abundantes. La composición de la comunidad de criptofauna difirió entre períodos con peces del género Scarus como el principal contribuyente a cualquier diferencia. El aumento en la abundancia y diversidad de criptofauna y peces puede reflejar el crecimiento de coral y la correspondiente disponibilidad de espacio y complejidad ambiental en el parche experimental. La composición de las comunidades de criptofauna fue generalmente consistente con otros estudios. Sin embargo, una alta densidad de simbiontes decápodos podría sugerir que, sin otras colonias de Pocillopora a las que trasladarse, pueden amontonarse a pesar de sus tendencias agresivas. Conclusiones: Las colonias de Pocillopora experimentarán un aumento de simbiontes que podrían contribuir positivamente a la salud y supervivencia del coral después del trasplante.

Body size and body conditions of two dung beetles species (Coleoptera: Scarabaeidae) related to environmental temperatures

ABSTRACT Temperature affects the body size of animals, which is an important trait in natural and sexual selection. Insects do not have complex mechanisms of temperature control, thus temperature changes affect their life aspects, from enzymatic reactions to behavior. The amount of fat stored by insects is also influenced by temperature and constitutes a tissue with biosynthetic and metabolic activity, acting as an energy reservoir. We assessed the effect of environmental temperature due to elevation and seasonal temperature variations on body size and condition of two dung beetles species: Canthon rutilans cyanescens and Dichotomius sericeus (Coleoptera: Scarabaeinae). Both species are abundant in southern Brazilian forests, but they differ in habits: the first is a diurnal roller whereas the later is a nocturnal tunneler. Summer months and sites with lower elevations and higher temperatures presented larger C. rutilans cyanescens. A linear relationship exists between body size and soil temperatures, whereas the temperature positively influences the body length. Furthermore, C. rutilans cyanescens from cooler sites had more body fat. Individuals of D. sericeus were also larger in summer months, however, we did not find differences in the proportion of fat or a relation between body size and temperature. Thus, the body size of dung beetle species varies in relation to temporal factors, as both species are larger in summer. More interesting was to observe that the species with a diurnal habit, even though smaller in colder places, has a higher proportion of fat, which indicates an evolutionary response to environmental pressure.

March or Die: road-killed herpetofauna along BR-040 highway, an ancient road on the Atlantic Forest from Southeastern Brazil / Marche ou Morra: herpetofauna atropelada ao longo da rodovia BR-040, uma antiga estrada na Mata Atlântica do Sudeste do Brasil

Abstract The construction of highways is responsible for access to previously protected areas, resulting in changes in landscape and dynamics of the animal populations that live in these areas. These enterprises are the major responsible for the mortality of wild animals, surpassing hunting and even the trafficking of animals. The objective of this study was to make a list that reflects the diversity of amphibians and reptile's road-killed along the BR-040, a highway that crosses the threaten lowland Atlantic Forest in Southeastern region of Brazil, including the use of microhabitats, lifestyle, activity pattern, reproductive cycles, and possible rare or endangered species. The study area consists of 180,4 km of highways. Monitoring began in 2006 and continues to the present day. A total of 1,410 individuals from 60 species were recorded in this study. The reptiles were more frequent in number of individuals and species. The commonest species recorded were Crotalus durissus and Dipsas mikanii. We have registered a single endangered species: Ranacephala hogei. The highest rates of road-kill were recorded during the wet season. Road-kills of fauna is a major threat to species, studies are of great importance to define plans that seek to mitigate the effects generated by these enterprises.

Resumo A construção de rodovias é responsável pelo acesso a áreas anteriormente protegidas, resultando em alterações na paisagem e na dinâmica das populações animais que vivem nessas áreas. Esses empreendimentos são os maiores responsáveis pela mortalidade de animais silvestres, superando a caça e até mesmo o tráfico de animais. O objetivo deste estudo foi realizar uma lista que reflita a diversidade de anfíbios e répteis atropelados ao longo da BR-040, uma rodovia que atravessa a ameaçada Mata Atlântica na região Sudeste do Brasil, incluindo o uso de microhabitats, estilo de vida, padrão de atividade, ciclos reprodutivos, e possíveis espécies raras ou ameaçadas. A área de estudo é constituída por 180,4 km de rodovias. O monitoramento começou em 2006 e segue até os dias atuais. Ao todo 1.410 indivíduos de 60 espécies foram registrados nesse estudo. Os répteis foram mais frequentes, em número de indivíduos e espécies. As espécies mais comumente registradas foram Crotalus durissus e Dipsas mikanii. Registramos uma espécie ameaçada de extinção: Ranacephala hogei. A maior taxa de atropelamento foi registrada durante a estação chuvosa. O atropelamento de fauna é uma grande ameaça as espécies, sendo de grande importância estudos para definição de planos que busquem mitigar os efeitos gerados por esses empreendimentos.

Democracia e educação escolar em tempos de pós-pandemia / Democracy and school education in post-pandemic times / La democracia y la educación escolar en tiempos de post-pandemia

RESUMO O objetivo desta nota é colocar em evidência alguns apontamentos para se pensar a educação escolar em tempo de pós-pandemia. As interfaces entre o processo formativo do sujeito e a educação escolar em tempo de pós-pandemia se encontram em um paradoxo: por um lado, a dificuldade na construção, pelo viés democrático, da proposta de ensino da unidade escolar como lugar para se fazer o espaço do comum, na partilha da cultura escolar; por outro lado, a exclusão que se encontra instituída no sistema educacional e que restringe o direito à educação.

ABSTRACT The aim of this article is to highlight some notes to think about school education in post-pandemic times. The interfaces between the subject's formative process and school education in post-pandemic times are in a paradox: on the one hand, the difficulty building, through democratic bias, the proposal of teaching the school unit as a place to make the space of the common, in sharing the school culture; on the other hand, the exclusion that is established in the educational system and that restricts the right to education.

RESUMEN El objetivo de esta nota es poner en evidencia algunos apuntes para pensar en la educación escolar en el tiempo post-pandemia. Las interfaces entre el proceso formativo del sujeto y la educación escolar en tiempo de post-pandemia se encuentran en una paradoja: por un lado, la dificultad de construir, por el sesgo democrático, la propuesta de enseñar la unidad escolar como lugar para hacer el espacio de lo común, compartir la cultura escolar; por otra parte, la exclusión que se ha establecido en el sistema educativo y que limita el derecho a la educación.

Concrete survivors: the herpetofauna of an urban green area over 100 years of increasing urbanization / Sobreviventes do concreto: a herpetofauna de uma áreaverde urbana ao longo de 100 anos de urbanização

Abstract Low biodiversity in urban areas is associated with habitat loss. However, the effects of urbanization on biodiversity should also consider the historical background of land-use, explored herein. Our goal was to evaluate changes in the assemblage of reptiles in an urban habitat over 100 years, aiming to identify which ecological attributes allowed the persistence of species that can be found in the area today. We accessed historical records in scientific collections and carried out fieldwork to access reptile assemblage in an urban green area, in São Paulo, Brazil. Considering land-use changes in the area, we defined three-time intervals between 1901 and 2020. We established species richness for each time interval, categorizing them into three ecological attributes: habitat preference, substrate use, and food habits. We recorded 27 reptile species from 1901 until 2020, 14 resulting from historical data, eight from both historical and fieldwork, and five species exclusively in fieldwork. Amphibians were also sampled during fieldwork, but not used in historical comparison. Reptile's species richness decreased 59% regardless of ecological attributes, and snakes were the group with most species' loss. Fossorial reptiles were the least affected group. We concluded that habitat loss culminated in a species richness decline, and the reptiles that remain until today were likely present since the fragment isolation. Ecological attributes of the remaining taxa include species that use terrestrial substrates and feed on prey commonly found in urban environments.

Resumo A baixa biodiversidade em áreas urbanas está associada à perda de habitat. No entanto, os efeitos da urbanização sobre a biodiversidade também devem considerar o histórico de uso da terra, explorado aqui. Nosso objetivo foi avaliar as mudanças na comunidade de répteis em um habitat urbano ao longo de 100 anos, visando identificar quais atributos ecológicos permitiram a persistência de espécies que podem ser encontradas na área hoje. Acessamos registros históricos em coleções científicas e realizamos trabalho de campo para levantar as espécies de répteis em uma área verde urbana, em São Paulo, Brasil. Considerando as mudanças de uso da terra na área amostrada, definimos três intervalos de tempo entre 1901 e 2020. Estabelecemos a riqueza de espécies para cada intervalo de tempo, categorizando-as em três atributos ecológicos: preferência de habitat, uso de substrato e hábitos alimentares. Registramos 27 espécies de répteis de 1901 até 2020, sendo 14 resultantes de dados históricos, oito de dados históricos e de campo e cinco espécies amostradas exclusivamente de campo. Anfíbios também foram amostrados durante o trabalho de campo, mas não foram usados na comparação histórica. A riqueza de espécies de répteis diminuiu 59% independentemente dos atributos ecológicos, e serpente foi o grupo com maior perda de espécies. Os répteis fossoriais foram o grupo menos afetado. Concluímos que a perda de habitat culminou em um declínio da riqueza de espécies, e os répteis que permanecem até hoje provavelmente estavam presentes desde o isolamento do fragmento. Os atributos ecológicos dos táxons remanescentes incluem espécies que utilizam substratos terrestres e se alimentam de presas comumente encontradas em ambientes urbanos.

Historia del Proyecto de Investigación en Servicios de Salud: Entrevista a Kerr White / History of Health Services Research Project: Interview with Kerr White

RESUMEN Se presenta la entrevista realizada en 1998 a Kerr L. White (1917-2014), traducida al español. White fue un economista, epidemiólogo, estadístico, médico general, sanitarista, muy crítico de la separación entre la investigación, la clínica, la epidemiología, la salud pública y las políticas de salud. Fue uno de los fundadores de la investigación sobre los servicios de atención médica. Su preocupación básica fue la responsabilidad de la sociedad para asignar recursos de atención médica de la manera más apropiada para mejorar la salud de las poblaciones. La producción de White señala críticamente la ausencia de una mirada poblacional en la epidemiología aplicada a servicios y sistemas de salud, y en la evaluación del impacto social y económico de las prácticas, señalando además la deshumanización de los procesos de atención y cuidado. Sus trabajos han sido poco citados en los textos del campo de la salud, por lo que recuperamos su figura con el objetivo de difundir la vigencia de su pensamiento y su obra.

ABSTRACT The interview conducted in 1998 with Kerr L. White (1917-2014) is presented, translated into Spanish. White, an economist, epidemiologist, statistician, general physician, and health advocate, was highly critical of the separation between research, clinical practice, epidemiology, public health, and health policies. He was one of the pioneers in healthcare services research. His primary concern was society's responsibility to allocate healthcare resources in the most appropriate way to improve the health of populations. White's work critically addresses the absence of a population perspective in epidemiology applied to healthcare services and systems, and the lack of evaluation of the social and economic impact of practices. He also highlights the dehumanization of care processes. Despite being undercited in health literature, we reintroduce his figure with the aim of disseminating the relevance of his thoughts and contributions.

Padrão de reprodução do capital: uma contribuição da teoria marxista da dependência à ecologia / Capital reproduction pattern: a contribution from marxist dependency theory to ecology

Resumo: Neste artigo, por meio de revisão bibliográfica, discutimos a ecologia a partir da categoria-padrão de reprodução do capital, destacando a dialética entre valor e valor de uso. Concluímos, com base na TMD, que a categoria-padrão de reprodução do capital permite compreender a ecologia no âmbito da particularidade, evidenciando que a valorização é sempre acompanhada da produção material e que distintos padrões de reprodução do capital impactam desigualmente o meio ambiente e a sociedade.

Abstract: In this article, through a literature review, we discuss ecology based on the standard category of capital reproduction, highlighting the dialectic between value and use-value. We conclude, based on TMD, that the standard category of capital reproduction enables the understanding of ecology within the realm of particularity, demonstrating that valorization is always accompanied by material production and that different patterns of capital reproduction unevenly impact the environment and society.

Association between suicidal ideation and exposure to socialecological risk factors among middle school students in Taiyuan City / 中国学校卫生

Objective@#To understand the current situation of suicidal ideation among middle school students in Taiyuan City and its correlation with exposure to social ecological risk factors, so as to provide a reference basis for exploring the causes of suicidal ideation among middle and high school students and formulating effective preventive measures.@*Methods@#A questionnaire survey was conducted among 2 639 middle school students in urban and rural areas of Taiyuan City by multistage stratified random cluster sampling, including general demography characteristics, social ecological risk factors and suicidal ideation. SPSS 26.0 software was used for Chi squared test and binary Logistic regression analysis.@*Results@#The overall detection rate of suicidal ideation was 24.7 %. There were statistically significant differences in the detection rate of suicidal ideation among middle school students in different gender, grade, family residence, maternal education level, perceived family economic conditions, number of close friends, self-perceived academic burden ( χ 2=38.17, 13.44, 10.77, 8.15, 19.76, 18.95, 59.75, P <0.05). After adjusting the general demography characteristics, the binary Logistic regression showed that moderate and high risk in the individual, family and cultural dimension, and high risk in the school dimension of the social ecology were all positively correlated with suicidal ideation among middle school students ( OR=1.38, 2.28, 1.97, 3.28, 1.48, 2.15, 1.71, P <0.05).@*Conclusion@#The suicidal ideation among middle school students is related to individuals, families, and schools in the social ecological microsystem, as well as the cultural environment in the macro system. It is necessary to conduct intervention in suicidal ideation at the individual, family, and school levels, meanwhile, strengthening social and cultural construction to reduce the impact of adverse factors on the mental health among adolescents.

Ecological construction of ESP curriculum system in medical schools under perspective of learning science / 中华医学教育探索杂志

English for specific purpose (ESP) courses for the postgraduates in medical schools have both physical and social attributes, with emphasis to improve practical language learning of medical specialties. It's an effective way to develop the English language application ability of high-level medical college students by constructing an ESP teaching and learning ecological system with professional and social contextual characteristics. In this study, through design-based implementation research, scenario simulation class was designed and implemented to accomplish task-based language teaching and learning. Further discussions on how to integrate blended and interrelated classes, on how to define combined and interactive teachers' role were explored. Based on the teaching and learning practices, organically combining the innovative curriculum concept with the construction of ESP ecological system effectively directs the practical application of the ESP class under the perspective of learning science, and verifies the feasibility of the ecological construction of ESP curriculum system.

A qualitative study to analyse the reasons for delayed medical treatment in diabetic foot patients based on a health ecology model / 中国实用护理杂志

Objective:To explore the reasons for delayed medical treatment in diabetic foot patients using the health ecology model as a framework.Methods:From November of 2021 to March of 2022, descriptive phenomenological research methods was used in 20 patients with diabetic foot who delayed medical treatment were interviewed face-to-face semi-structured in depth, and the data analysis was carried out using the seven-step method of Colaizzi phenomenology to refine the theme.Results:According to the five levels of the health ecology model, the reasons for delayed medical treatment were summarized into 11 themes, and the reasons for the personal trait layer included foot ulcers are not detected promptly, and the perceptual decline of advanced patients. Behavioral characteristics included lack of knowledge of diabetic foot, negative medical psychology. Reasons for the interpersonal network included insufficient family support and lack of social support; reasons for living and working conditions included high economic pressure, low electronic health literacy, and inconvenient medical treatment; the reasons for the policy environment included uneven medical insurance reimbursement ratios and limited medical conditions.Conclusions:The reason for the delay in seeking medical treatment for diabetic foot patients is multi-layered and systematic, and medical staff need to improve the self-management ability of diabetic patients′ feet from the individual level, and also need to guide patients from the system level on how to obtain the best medical resources.

Research progress on the influencing factors of health literacy in patients with coronary heart disease based on the perspective of health ecology / 中国实用护理杂志

The self-health management level of patients with coronary heart disease depends largely on their health literacy level. The theory of health ecology believes that the factors affecting individual health are multi-level. Based on the perspective of health ecology, this paper analyzed the influencing factors of health literacy of patients with coronary heart disease from five aspects: personal characteristics, behavior, interpersonal network, living and working conditions, environmental policies, so as to provide a basis for formulating targeted and systematic strategies for improving the health literacy of patients with coronary heart disease in the future.

Ambiente, saúde e covid-19: da crise global à existência sustentável / Environment, health, and the COVID-19: from global crisis to sustainable existence

Resumo Este ensaio busca analisar os impactos sociossanitários exercidos pelo meio ambiente, incorporando as dinâmicas trazidas pela covid-19 e evidenciando as repercussões da pandemia. O coronavírus atingiu sobretudo países que falharam na prevenção e não estabeleceram medidas de intervenção eficazes e colaborativas. A destruição da natureza se intensificou na pandemia, assim como as ameaças enfrentadas por seus defensores, o que agravou ainda mais a crise. Nesse contexto pode-se destacar os riscos apresentados aos indígenas brasileiros e aos ambientalistas latino-americanos; o surgimento de grupos perigosos; e a implementação de políticas governamentais de efeitos críticos que afetam a preservação ambiental e colocam em risco os modos de vida tradicionais. Assume-se, desse modo, que o planeta enfrenta uma crise sanitária, mas também socioeconômica e ambiental. Para que tal crise heterogênea seja superada, os esforços precisam ser multiformes, envolvendo: cuidados à saúde e aos ecossistemas; diminuição da pobreza global e da desigualdade sanitária; redução de riscos ambientais; proteção dos modos de vida tradicionais; defesa das democracias e dos direitos humanos; fomento de políticas de desenvolvimento sustentável; e cooperação internacional. Tais esforços também incidirão sobre os anos vindouros, minimizando os riscos de novas pandemias e atuando na preservação ambiental.

Abstract This essay analyzes the socio-sanitary impacts exerted by the environment, incorporating the dynamics brought about by the COVID-19 pandemic and unveiling its repercussions. Countries that failed to prevent the virus spread and to established effective and collaborative intervention measures were hit the hardest. Environmental destruction reached new heights in the pandemic, as have the threats faced by its defenders, further aggravating the crisis. In this scenario one can highlight the risks posed to Brazilian Indigenous peoples and Latin American environmentalists; the emergence of dangerous groups; and the implementation of government policies with critical effects on environmental preservation that put traditional ways of life at risk. It is thus recognized that the planet faces not only a health crisis, but also a socioeconomic and environmental one. To overcome such heterogeneous crisis, efforts must be multifaceted, involving: caring for health and ecosystems; eliminating global poverty and sanitary inequality; reducing environmental risks; protecting traditional ways of life; defending democracies and human rights; and fostering sustainable development policies and international cooperation. These efforts will also affect the years to come, minimizing the risks of new pandemics and acting to preserve the environment.
