resumen está disponible en el texto completo

ABSTRACT University social responsibility is a set of actions that helps to promote the active participation of students in their university education, with ethical conduct to create a culture of social commitment based on values and academic quality. The main role of the university is to develop the functions of teaching, research and social responsibility; this allows creating a broader vision of the needs in the community, generating competent professionals and causing a positive impact (Palomino, Vázquez, Vicente, & Tomás, 2019). Objective: To identify the main authors of the subject from the systematic review of the literature, to point out the four axis that RSU has and the four university impacts. Materials and methods: This research is exploratory and documentary with a qualitative approach. The information sources used correspond to consultation pages, among which are: Google academic, and Lens.org. Likewise, inclusion and exclusion criteria were used to collect information and the results obtained were delimited after adding search conditions such as the year interval from 2017 to 2023. Another limitation is that they were only review articles and in any language. Results: The results obtained were 10 definitions of prominent authors which haves an impact on the fact that the University social responsibility has 8 dimensions among which are: Responsible Campus, Citizen Education, Social Knowledge Management, and Mutual Learning Communities for Development, Organizational, Educational, Cognitive and social. The four axis of the RSU are the basis of the organizations to be able to fulfill the mission that each university community pursues. Within the responsible campus, care is taken to ensure that environmental and sustainable care is met and students are taught to participate in it. , responsible citizen and professional training, deontology, which is the duty of people, this helps the university community to do things ethically and with good morals inside and outside universities, knowledge management is a of the main tasks of higher education institutions, social work, the reason for being of various organizations, thanks to which they can disseminate their knowledge and contribute to the development of community and group culture, and finally the need for The society of inclusion and communication between people occur within communities of mutual learning for development. The organizational impacts, within the RSU, impact people, management and sustainability. The educational impacts are related to the training of students (their ethics, their way of interpreting the world and the social role that corresponds to them) and involves all university processes (curriculum, central administration and knowledge management policies). Cognitive impacts are the dissemination of knowledge and social impacts are the relationship within and on the university campus, the treatment and participation of students; Students in the different branches offered. When reviewing and reading the different existing articles, it was observed that there is little information regarding the RSU, focusing on a chronology of the different authors from 2014 to date. Within the articles reviewed, it can be defined that RSU trains, teaches, supports, promotes, guides and organizes; involving the student community, teachers, administrative and managerial staff. The RSU transmits responsible knowledge, ethical principles and helps to train responsible citizen professionals. Conclusion: After studying the literary review, it can be mentioned that all the axis of the RSU must have the participation of the students and all the people who make up the university community in order to have a responsible university, both internally and externally, according to the different concepts that are mentioned of University Social Responsibility; In other words, it is a way to help the professional and civic training of all students, since this is part of what social responsibility seeks. It is mentioned that university students must get involved in real problems within their professional and civic training, since this helps to create links between learning and social responsibility and thus be able to promote human development, both ethically and morally, as that participation in the different projects that the same institution carries out in its activities will grow.Ramírez (2020),Quezada and Rodríguez (2019),Arauco and Apaza (2022),Évora (2017), agree that RSU is reflected in the existence of four axis for the socially responsible management of universities, so that the students are aware that everything that is done within the institution will be reflected outside of it. Complying with Social Responsibility in higher education is a transformation resource that promotes compliance with transparent practices and ethical conduct for sustainable development, generating social well-being on the university campus for the comprehensive and ideal training of its students. Currently, globalization leads to constant changes in organizations and forces them to be able to identify their challenges for the new trends that their environment requires. Therefore, globalization, competition, technology, social responsibility, knowledge and intangible assets demand serious modifications in their structures and strategies from companies.Niebles Nuñez et al. (2018)the universities have the important mission of equitably distributing knowledge and social information. That is why universities must assume the position of University Social Responsibility and analyze whether effective or null knowledge is being provided. The current era is characterized by its constant change, in social demands, in the role of traditional actors, in the situation at the regional and international level, in development approaches (Uribe et al., 2020). Addressing the issue of RSU requires articulating the various parts of the institution in an equitable and sustainable social promotion project, for the production and transmission of responsible knowledge and the training of equally responsible citizen professionals (Mosquera Tayupanta and Alba Granados, 2021; Peña y otros, 2017). There is a proposal for university social responsibility that provides a space for participation in the activities carried out and that are adapted to the new acquisition modalities for students, in addition to the fact that university social responsibility seeks not only to work on the axis of transformation within of the institution, but is also aimed at the entire society that is involved (Pedró, 2019). The university must promote the participation of its students in cultural, social, sports and environmental activities.

Procesamiento Asistido de Situaciones Estresantes Recientes: estudio sudamericano en personal de rescate y emergencias / Assisted Processing of Recent Stressful Situations: A South American Study in rescue and emergency Personnel

Resumen Actualmente, los rescatistas y el personal de emergencias que asiste a la comunidad en situaciones de desastre no cuentan con un tratamiento adecuado que proteja su salud mental. Las técnicas más ampliamente utilizadas como el debriefing y el defusing resultarían inefectivas para tal fin, e incluso perjudiciales a largo plazo. En el presente estudio se llevaron adelante dos cuasiexperimentos con 42 rescatistas bolivianos y 39 peruanos, para probar los efectos de la aplicación grupal de la técnica de Procesamiento Asistido en Situaciones Estresantes Recientes (PASER) en la reducción de los niveles de reactividad ansiosa vinculados al recuerdo de labores de rescate. Se utilizó el inventario de Autopercepción del Estado Emocional (APEEM), para evaluar la intensidad del recuerdo. Los resultados indicaron que la asistencia externa a la memoria de trabajo a través de la aplicación de la técnica PASER redujo significativamente la autopercepción de los niveles de perturbación emocional asociados al recuerdo en rescatistas peruanos t(38) = 6.642; p < .0001 y bolivianos t(24)=7.452; p < .0001. Estas primeras observaciones indican que la técnica PASER, aplicada de forma temprana y grupal a rescatistas y personal de emergencias, resultaría adecuada para la prevención de trastornos de ansiedad y estrés derivados de las tareas tensionantes de sus labores. La reducción temprana de esta sintomatología evitaría los frecuentes problemas de comorbilidad que conllevan los síntomas de ansiedad no tratados. Resultan necesarios nuevos estudios longitudinales para verificar la eficacia de esta intervención a largo plazo.

Abstract Currently, rescuers and emergency personnel who assist the community in disaster situations do not have adequate treatment to protect their mental health. The most widely used techniques such as debriefing and defusing would be ineffective and even harmful in the long term. In the present study, two quasi-experiments were conducted with 42 Bolivian and 39 Peruvian rescuers to test the effects of group application of the Assisted Processing in Recent Stressful Situations (PASER, for its Spanish acronym) technique on the reduction of levels of anxious reactivity associated with the memory of rescue tasks. The Self-Perception of Emotional State Inventory (APEEM, for its Spanish acronym) was used to assess the intensity of recall. Results indicated that external support of working memory through the application of the PASER technique significantly reduced self-perceived levels of emotional disturbance associated with recall in both Peruvian t(38) = 6.642; p < .0001 and Bolivian rescue workers t(24) = 7.452; p < .0001. These initial observations suggest that the PASER technique, applied early and in groups to rescuers and emergency personnel, would be appropriate for the prevention of anxiety and stress disorders resulting from the stressful tasks of their work. Early reduction of this symptomatology would avoid the frequent comorbidity problems associated with untreated anxiety symptoms. Further longitudinal studies are needed to verify the long-term effectiveness of this intervention.

Planetary health risks in urban agriculture / 《全球健康杂志（英文）》

Urban agriculture is gaining recognition for its potential contributions to environmental resilience and climate change adaptation,providing advantages such as urban greening,reduced heat island effects,and decreased air pollution.Moreover,it indirectly supports communities during weather events and natural disasters,ensur-ing food security and fostering community cohesion.However,concerns about planetary health risks persist in highly urbanized and climate-affected areas.Employing electronic databases such as Web of Science and PubMed and adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines,we identified 55 relevant papers to comprehend the planetary health risks associated with urban agriculture.The literature review identified five distinct health risks related to urban agriculture:(1)trace metal risks in urban farms;(2)health risks associated with wastewater irrigation;(3)zoonotic risks;(4)other health risks;and(5)social and eco-nomic risks.The study highlights that urban agriculture,while emphasizing environmental benefits,particularly raises concerns about trace metal bioaccumulation in soil and vegetables,posing health risks for populations.Other well studied risks included wastewater irrigation and backyard livestock farming.The main limitations in the available literature were in studying infectious diseases and antibiotic resistance associated with urban agriculture.

Chronic pain among older adults and its impact on satisfaction with social participation: development and validation of the "Instrument to Assess Older Adults' Social Participation". A descriptive quantitative study

ABSTRACT BACKGROUND: We aimed to develop and validate a practical instrument to assess older adults' satisfaction with their social participation (SP). DESIGN AND SETTING: This methodological validation study was conducted at a public higher education institution. METHODS: A two-phase study was designed, developed, and validated to assess older adults' satisfaction with their SP. In the first phase, we conceptualized SP and developed an "instrument to assess older adults' satisfaction with their SP (IAPSI)," as approved by a committee of specialists, pre-tested, and partially validated. Second, we determined the IAPSI's reproducibility using Cronbach's alpha to measure internal consistency, Pearson's and Spearman's coefficients to measure correlations, the Bland-Altman plot and intraclass correlation coefficient (ICC) to measure reproducibility. We also generated a receiver operating characteristic (ROC) curve. RESULTS: 102 older adults (mean age, 87.29) participated in the first phase. Moderate internal consistency (Cronbach's alpha 0.7) and significant moderate correlations with quality of life by World Health Organization Quality of Life (WHOQOL)-bref and by WHOQOL-old social domains (Pearson's coefficients 0.54 and 0.64, respectively; P < 0.001) were found. The ROC curve indicated an IAPSI score of 17 as the threshold for the impact of pain on satisfaction with SP (83.3% sensitivity and 88.9% specificity, P < 0.001). In the second phase, 56 older adults (between 81 and 90 years old) participated. We found adequate intra- and inter-observer reproducibility for the IAPSI (ICC 0.96 and 0.78, respectively). CONCLUSION: We have developed a practical instrument with appropriate psychometric properties to assess older adults' satisfaction with their SP.

Impacts of mining on local fauna of wildlife in District Mardan & District Mohmand Khyber Pakhtunkhwa Pakistan / Impactos da mineração na fauna local da vida selvagem nos Distritos de Mardan e de Mohmand, Khyber Pakhtunkhwa, Paquistão

Abstract Mining is vital for human sustenance and a crucial sector in the state economy. However, its impacts on the environment and biodiversity cannot be underestimated. Which are potent to the attract government's attention. Environment and wildlife are subject to the harmful impacts of mining and its related activities. In this study, districts, namely Mardan and Mohmand have been targeted with respect to mining impacts. The assessment was carried out on wildlife adversely affected by the mining sector. The fauna has been keenly observed to bring the calculated risks and threat perception of the regional wildlife. Total 9 species of mammals, 21 species of birds, were recorded in District Mardan. While in District Mohmand 2 species of mammals, 9 species of birds, and 4 species of reptiles were studied. The Study explored that mining primarily responsible for land degradation. Which lead to food and agriculture losses. Several other factors like blasting, pollution, hunting, deforestation, habitat loss was also observed. Deforestation surfaced one of the major causes for extinction of fauna in the said region. preemptive measures are needed to seize the man-made catastrophe.

Resumo A mineração é vital para o sustento humano e um setor crucial na economia do Estado. No entanto, seus impactos sobre o meio ambiente e a biodiversidade não podem ser subestimados, visto serem potentes para atrair a atenção do governo. O meio ambiente e a vida selvagem estão sujeitos aos impactos prejudiciais da mineração e de suas atividades relacionadas. Neste estudo, os distritos, nomeadamente Mardan e Mohmand, foram selecionados ​​no que diz respeito aos impactos da mineração. A avaliação foi realizada em animais selvagens afetados negativamente pelo setor de mineração. A fauna tem sido observada atentamente para trazer os riscos calculados e a percepção de ameaça à vida selvagem regional. Um total de nove espécies de mamíferos, 21 espécies de pássaros, foi registrado no Distrito Mardan. Enquanto no Distrito Mohmand, duas espécies de mamíferos, nove espécies de pássaros e quatro espécies de répteis foram estudadas. O estudo explorou essa mineração que é principalmente responsável pela degradação do solo, acarretando perdas de alimentos e na agricultura. Vários outros fatores como explosões, poluição, caça, desmatamento, perda de habitat também foram observados. O desmatamento veio à tona como uma das principais causas de extinção da fauna da região, e tem-se que medidas preventivas são necessárias para dimensionar a catástrofe provocada pelo homem.

Assessment of particulate matter (PM) in ambient air of different settings and its associated health risk in Haripur city, Pakistan

Abstract Particulate matter (PM) is a major air pollutant causing serious health problems. The aim of the present study was to find out concentration of PM in ambient air and its associated health risk in Haripur city, Pakistan. Twenty-three samples were taken at various educational institutes, hospitals, recreational areas and industries in Haripur city. Concentration of PM2.5 (µg/m3) and PM10 (µg/m3) was measured with Youngteng YT-HPC 3000A portable PM counter. The results revealed that values of both PM2.5 and PM10 were above the permissible limits (35 µg/m3 for PM2.5 and 150 µg/m3 for PM10) set by Environmental Protection Agency Pakistan (Pak-EPA) in all the educational institutes, hospitals, recreational areas and industries investigated. Furthermore, significant (p 0.05) variation was found in the concentration of both PM2.5 and PM10 in all the educational institutes, hospitals, recreational areas, and industries studied. The concentration of PM2.5 was positively correlated with the concentration of PM10 in all the sampling sites. Therefore, from 1-14 scale standard of health index, the values of PM2.5 and PM10 exhibited that the ambient air quality of Haripur city Pakistan is under high risk. If the regulatory authorities such as Environmental Protection Agency, Health Department and Local Government monitor PM pollution in different settings of Haripur city, then a decrease can be possible in the pollution level. The remedies that can be taken to overcome the problem of ambient air pollution such as PM are plantation of trees at the sites where there are higher levels of air pollutants and use of masks on personal protection basis along with implementation of pollution control system in industries of Hattar Industrial Estate Haripur city, Pakistan.

Resumo O material particulado (MP) é um importante poluente do ar que causa sérios problemas de saúde. O objetivo do presente estudo foi descobrir a concentração de MP no ar ambiente e sua associação com o risco à saúde na cidade de Haripur, Paquistão. Vinte e três amostras foram coletadas em várias instituições de ensino, hospitais, áreas recreativas e indústrias na cidade de Haripur. A concentração de MP2,5 (µg/m3) e MP10 (µg/m3) foi medida por meio do contador de MP portátil Youngteng YT-HPC 3000A. Os resultados revelaram que os valores de MP2,5 e MP10 estavam acima dos limites permitidos (35 µg/m3 para MP2,5 e 150 µg/m3 para MP10) estabelecidos pela Agência de Proteção Ambiental do Paquistão (Pak-EPA) em todas as instituições de ensino, hospitais, áreas recreativas e indústrias investigadas. Além disso, foi encontrada variação significativa (p 0,05) na concentração de MP2,5 e MP10 em todos os locais estudados. A concentração de MP2,5 correlacionou-se positivamente com a concentração de MP10 em todos os locais de amostragem. Portanto, a partir da escala padrão 1-14 do índice de saúde, os valores de MP2,5 e MP10 mostraram que a qualidade do ar ambiente na cidade de Haripur, Paquistão, está sob alto risco. Se as autoridades reguladoras, como a Pak-EPA, o Departamento de Saúde e o governo local, monitorarem a poluição por MP em diferentes configurações da cidade de Haripur, pode ser que haja uma diminuição no nível de poluição. As medidas que podem ser tomadas para superar o problema da poluição do ar ambiente, como o MP, são o plantio de árvores nos locais onde há maiores níveis de poluentes atmosféricos, o uso de máscaras e a implantação de sistema de controle de poluição nas propriedades industriais de Hattar, na cidade Haripur, Paquistão.

Impactos do TDAH à Adolescência: Revisão Sistemática de Literatura / Impacts of ADHD on Adolescence: Systematic Literature Review

RESUMO: Transtorno do Déficit de Atenção com Hiperatividade (TDAH) é um transtorno do neurodesenvolvimento caracterizado por níveis prejudiciais de desatenção e/ou hiperatividade-impulsividade. Foram investigados resultados obtidos em pesquisas sobre impactos do TDAH ao adolescente e foi utilizada a recomendação PRISMA 2020. As bases de dados consultadas foram: APA PsycNet, Lilacs, Medline, PubMed Central, Scorpus, SciELO, a partir dos seguintes descritores: Transtorno do Déficit de Atenção e Hiperatividade, TDAH, Attention Deficit Hyperactivity Disorder, ADHD e Adolescente, Adolescentes, Adolescência, Adolescent, Teenager e Adolescence. Os critérios de inclusão foram: artigos publicados em periódicos entre janeiro de 2001 e janeiro de 2021, em português e inglês, completos e disponíveis online, estudos empíricos, revisados por pares, terem adolescentes como participantes e apresentarem no título, resumo ou corpo do texto os descritores referidos. Os dados foram tratados e organizados conforme check list (recomendação PRISMA 2020). Análises estatísticas descritivas foram realizadas com o Excel 2019. Para apresentar os resultados, utilizaram-se o fluxograma PRISMA, quadro e figuras. Incluíram-se 68 artigos que apontaram variedade de impactos negativos ao desenvolvimento do adolescente nas áreas sociais/relacionais, comportamentais, biológicas, neurológicas, cognitivas, psicológicas e psicopatológicas. Possível limitação desta revisão pode ser a não inclusão de artigos em outros idiomas, além do inglês e português. Os resultados sugerem multidimensionalidade dos impactos do TDAH ao adolescente, requerendo abordagem pluridimensional para evitar cronicidade, reduzindo seus efeitos ao desenvolvimento.

ABSTRACT: Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by harmful levels of inattention and/or hyperactivity-impulsivity. Results obtained from research on the impact of ADHD on adolescents were investigated and the PRISMA 2020 recommendation was used. The databases consulted: were APA PsycNet, Lilacs, Medline, PubMed Central, Scorpus, SciELO, from the following descriptors: Transtorno do Déficit de Atenção e Hiperatividade, TDAH, Attention Deficit Hyperactivity Disorder, ADHD and Adolescente, Adolescentes, Adolescência, Adolescent, Teenager and Adolescence. The inclusion criteria were: articles published in journals between January 2001 and January 2021, in Portuguese and English, complete and available online, empirical studies, peer reviewed, with adolescents as participants and presenting in the title, abstract or body of the text the referred descriptors. The data were processed and organized according to the check list (PRISMA 2020 recommendation). Descriptive statistical analyzes were performed using Excel 2019. The PRISMA flowchart, table and figures were used to present the results. Sixty-eight articles were included that pointed to a variety of negative impacts on adolescent development in the social/relational, behavioral, biological, neurological, cognitive, psychological and psychopathological areas. A possible limitation of this review may be the non-inclusion of articles in languages other than English and Portuguese. The results suggest the multidimensionality of the impacts of ADHD on adolescents, requiring a multidimensional approach to avoid chronicity, reducing its effects on development.

Particulate matter (PM) is a major air pollutant causing serious health problems. The aim of the present study was to find out concentration of PM in ambient air and its associated health risk in Haripur city, Pakistan. Twenty-three samples were taken at various educational institutes, hospitals, recreational areas and industries in Haripur city. Concentration of PM2.5 (µg/m3) and PM10 (µg/m3) was measured with Youngteng YT-HPC 3000A portable PM counter. The results revealed that values of both PM2.5 and PM10 were above the permissible limits (35 µg/m3 for PM2.5 and 150 µg/m3 for PM10) set by Environmental Protection Agency Pakistan (Pak-EPA) in all the educational institutes, hospitals, recreational areas and industries investigated. Furthermore, significant (p<0.05) variation was found in the concentration of both PM2.5 and PM10 in all the educational institutes, hospitals, recreational areas, and industries studied. The concentration of PM2.5 was positively correlated with the concentration of PM10 in all the sampling sites. Therefore, from 1-14 scale standard of health index, the values of PM2.5 and PM10 exhibited that the ambient air quality of Haripur city Pakistan is under high risk. If the regulatory authorities such as Environmental Protection Agency, Health Department and Local Government monitor PM pollution in different settings of Haripur city, then a decrease can be possible in the pollution level. The remedies that can be taken to overcome the problem of ambient air pollution such as PM are plantation of trees at the sites where there are higher levels of air pollutants and use of masks on personal protection basis along with implementation of pollution control system in industries of Hattar Industrial Estate Haripur city, Pakistan.

O material particulado (MP) é um importante poluente do ar que causa sérios problemas de saúde. O objetivo do presente estudo foi descobrir a concentração de MP no ar ambiente e sua associação com o risco à saúde na cidade de Haripur, Paquistão. Vinte e três amostras foram coletadas em várias instituições de ensino, hospitais, áreas recreativas e indústrias na cidade de Haripur. A concentração de MP2,5 (µg/m3) e MP10 (µg/m3) foi medida por meio do contador de MP portátil Youngteng YT-HPC 3000A. Os resultados revelaram que os valores de MP2,5 e MP10 estavam acima dos limites permitidos (35 µg/m3 para MP2,5 e 150 µg/m3 para MP10) estabelecidos pela Agência de Proteção Ambiental do Paquistão (Pak-EPA) em todas as instituições de ensino, hospitais, áreas recreativas e indústrias investigadas. Além disso, foi encontrada variação significativa (p < 0,05) na concentração de MP2,5 e MP10 em todos os locais estudados. A concentração de MP2,5 correlacionou-se positivamente com a concentração de MP10 em todos os locais de amostragem. Portanto, a partir da escala padrão 1-14 do índice de saúde, os valores de MP2,5 e MP10 mostraram que a qualidade do ar ambiente na cidade de Haripur, Paquistão, está sob alto risco. Se as autoridades reguladoras, como a Pak-EPA, o Departamento de Saúde e o governo local, monitorarem a poluição por MP em diferentes configurações da cidade de Haripur, pode ser que haja uma diminuição no nível de poluição. As medidas que podem ser tomadas para superar o problema da poluição do ar ambiente, como o MP, são o plantio de árvores nos locais onde há maiores níveis de poluentes atmosféricos, o uso de máscaras e a implantação de sistema de controle de poluição nas propriedades industriais de Hattar, na cidade Haripur, Paquistão.

Thematic assessment report on invasive alien species in Brazil: summary for policymakers / Relatório temático sobre espécies exóticas invasoras no Brasil: sumário para tomadores de decisão

Abstract Biological invasions are one of the major threats to biodiversity and good quality of life, resulting from the translocation of species by human action. There are more than 500 alien species currently invading ecosystems in Brazil, particularly plants and fishes, while little is known about invasive microorganisms. Although invasive alien species are present in all ecosystems in the country, most have been recorded in habitats with greater human interference, such as urban and peri-urban areas, farmland, dams, reservoirs, ports, and canals. Historically, the southern and southeastern regions of Brazil have had more invasive alien species, but there has been an increase in the number of invasive alien species in the central-western and northern regions in recent decades. The ornamental trade of plants and fishes as well as the illegal pet trade of wild mammals and reptiles are some of the main pathways for invasive species introduction and spread in Brazil. Breeding and cultivation systems that allow escape to natural areas are a relevant route of species introductions in freshwater ecosystems, while unintentional introductions from shipping and infrastructure are of extreme concern in marine ecosystems. The negative impacts of invasive alien species on the biota mainly include changes in community structure and local decrease in native species richness, mediated by predation, competition, and ecosystem changes. Most negative impacts are recorded for intentionally introduced species, such as fishes and plants, but unintentional introductions have led to impacts on good quality of life, with associated costs and impacts on human health. The management of biological invasions faces challenges that need to be overcome, such as the lack of public knowledge about the impact of invasive alien species, the popular appeal of charismatic invasive species or those used by humans, and the use of controversial control techniques. However, successful experiences of eradication and control in terrestrial and marine ecosystems have been recorded, some of them involving public engagement in management actions. Recognizing the issue as a cross-cutting public policy and developing ongoing governance experiences are fundamental goals for the management of invasive alien species in Brazil.

Resumo Invasões biológicas são uma das maiores ameaças à biodiversidade e à boa qualidade de vida, ocorrendo a partir da translocação de espécies por ação humana. Existem mais de 500 espécies exóticas invadindo ecossistemas atualmente no Brasil, com destaque para plantas e peixes. Pouco se sabe sobre microrganismos invasores. Apesar de existirem espécies exóticas invasoras em todos os ecossistemas no país, a maior parte dos registros foi feita em hábitats com maior interferência humana, como áreas urbanas, periurbanas, terras cultivadas, represas, reservatórios, portos e canais. Historicamente, as regiões sul e sudeste do Brasil apresentam mais espécies exóticas invasoras, mas nas últimas décadas se tem observado um aumento no número de espécies exóticas invasoras nas regiões centro-oeste e norte. O comércio de plantas e peixes ornamentais, assim como o comércio ilegal de mamíferos e répteis silvestres como animais de estimação são algumas das principais vias de introdução e disseminação de espécies exóticas invasoras no Brasil. Sistemas de criação e cultivo que possibilitam o escape para áreas naturais são uma relevante via de introdução em ecossistemas de águas continentais, enquanto introduções não intencionais a partir de navegação e de infraestrutura são de extrema preocupação em ecossistemas marinhos. Os impactos negativos de espécies exóticas invasoras sobre a biota incluem principalmente alterações na estrutura de comunidades e diminuição local da riqueza de espécies nativas, mediados por predação, competição e modificações ecossistêmicas. A maior parte dos impactos negativos registrados ocorreram para espécies introduzidas intencionalmente, como peixes e plantas, mas introduções não intencionais têm levado a impactos na boa qualidade de vida, com custos associados e impactos sobre a saúde humana. A gestão de invasões biológicas esbarra em desafios a serem superados, tais como a falta de conhecimento do público sobre o impacto de espécies exóticas invasoras, o apelo popular de espécies invasoras carismáticas ou utilizadas por humanos e o emprego de técnicas controversas de controle. Entretanto, experiências bem-sucedidas de erradicação e controle em ecossistemas terrestres e marinhos têm sido registrados, alguns deles envolvendo engajamento público nas ações de manejo. Reconhecer o tema como uma política pública transversal e desenvolver experiências continuadas de governança são metas fundamentais para a gestão e o manejo de espécies exóticas invasoras no Brasil.

Transposição do rio São Francisco: arte-fatos literários sobre saúde mental e o conto da implementação de megaempreendimentos no Brasil / The transposition of the São Francisco river: literary art-facts about mental health and the tale of mega-project implementation in Brazil

Resumo A justificativa para a implementação de megaempreendimentos no Brasil perpassa discursos de interesse político, econômico, social e ambiental, a fim de promover o desenvolvimento do país. Neste levantamento, busca-se compreender como são contadas as histórias sobre a implementação dessas iniciativas em territórios onde povos camponeses habitam cotidianamente, bem como lançar um olhar para a interface entre megaempreendimentos e saúde mental, a fim de provocar reflexões que possibilitem a criação de ações interventivas de cuidado em saúde mental com os povos camponeses. Trata-se de uma revisão integrativa que consultou quatro bases de dados e analisou 36 escritos, que apontaram importantes considerações como o fato de a implementação de megaempreendimentos impactar diversos âmbitos da vida daqueles que residem no percurso das obras, ocasionando um processo de vulnerabilização desses povos. Quanto à saúde mental da população rural, sua compreensão na literatura ainda se focaliza na presença de transtornos. Ancorada no binômio saúde-doença, verifica-se a invisibilização da pluralidade de sentidos que a saúde mental tem para povos camponeses, bem como o desinteresse em conhecer os caminhos trilhados no próprio território para o encaminhamento do cuidado em saúde mental, através de seus saberes, cosmologias e tradições.

Abstract The justification for mega-project implementation in Brazil permeates discourses of political, economic, social and environmental interest aimed at promoting its development. This survey aims to understand how stories about the implementation of mega-projects in territories in which peasant people live on a daily basis have been told, as well as to look at the interface between mental health and mega-projects to provoke reflections that enables the creation of interventional actions for the mental health care of people in rural areas. This integrative review uses four databases. A total of 36 writings were integrated for analysis, which pointed out important considerations: the implementation of mega-projects impacts several different areas, leading to a process of vulnerability experienced by the people who live at the site of these construction works. As for the mental health of the rural population, its understanding in the literature is still shown from the focus on the presence of the disorder. Anchored in the health-disease binomial, it makes the plurality of meanings mental health has for rural people invisible and shows a lack of interest in knowing the paths taken in their own territory for mental health care referrals by their knowledge, cosmologies, and traditions.

Vítimas indiretas da violência: um olhar sobre os impactos na saúde / Indirect victims of violence: a look at health impacts

Resumo Buscou-se investigar as percepções das vítimas indiretas, ou familiares de vítimas de homicídio, sobre as repercussões dessa morte em sua saúde. Fez-se um estudo qualitativo, exploratório, descritivo, a partir de oito entrevistas individuais semiestruturadas com dois grupos: familiares de agentes policiais vitimados por violência letal, e familiares de pessoas mortas em decorrência de intervenção policial, aqui designada como homicídio. Ambos os grupos relataram a percepção de que sua saúde piorou após o homicídio, e mencionaram problemas de depressão, síndrome do pânico, insônia, problemas cardíacos e distúrbios alimentares. Destacaram ainda a aquisição de hábitos danosos à saúde, como consumo de bebidas alcoólicas, tabaco e automedicação, e o agravamento de problemas de saúde pré-existentes. Observou-se que o homicídio praticado e sofrido por agentes policiais afeta vários aspectos da vida das vítimas indiretas que são indissociáveis das questões de saúde em sentido ampliado. Essas pessoas também são vítimas dessa violência, embora muitas vezes tenham seu sofrimento invisibilizado. Estudar o tema contribui para dar espaço ao sofrimento e ao luto, e para subsidiar a melhor atuação das instituições e serviços envolvidos.

Abstract We sought to investigate the perceptions of indirect victims or family members of homicide victims, about the repercussions of these deaths on their health. A qualitative, exploratory, descriptive study was carried out, based on eight semi-structured individual interviews with two groups: family members of police officers victimized by lethal violence, and family members of people killed as a result of police intervention, designated here as homicide. Both groups reported the perception that their health deteriorated after the homicide, and mentioned problems such as depression, panic disorder, insomnia, heart conditions and eating disorders. They also highlighted the acquisition of habits that are harmful to health, such as the consumption of alcoholic beverages, tobacco and self-medication, and the worsening of pre-existing health issues. It was observed that the homicide committed and suffered by police agents affects various aspects of the lives of indirect victims that are inseparable from health issues in a broader sense. These people are also victims of this violence, although their suffering is often made invisible. Studying this topic helps to give space to the suffering and mourning of these people and to subsidize the best performance of the institutions and services involved.

O impacto psicossocial da pandemia da covid-19 em lésbicas, gays, bissexuais e transgêneros (LGBT) na Colômbia / The psychosocial impact of the covid-19 pandemic on lesbian, gay, bisexual and transgender (LGBT) people in Colombia / El impacto psicosocial de la pandemia del covid-19 en las personas lesbianas, gais, bisexuales y transgénero (LGBT) en Colombia

Resumo Este artigo analisa o impacto dos fatores psicossociais provocado pela pandemia da covid-19 em lésbicas, gays, bissexuais e transgêneros (LGBT) na Colômbia. Trata-se de um estudo exploratório misto, que utilizou dados qualitativos para explicar os dados quantitativos, com ênfase na interpretação das relações entre ambos. Para tanto, foram utilizados como instrumentos um questionário e grupos de estudo. Participaram do estudo 219 pessoas LGBT, sendo 18 lésbicas, 128 gays, 36 bissexuais e 37 pessoas transgênero. Os impactos psicossociais mais significativos associados à covid-19 foram relacionados a fatores econômicos (como desemprego e diminuição da renda familiar), conflitos familiares (como perda da privacidade da população LGBT que tiveram que retornar a seu lar de origem) e tensões nas relações sociais, gerando insegurança, medo e ansiedade nessa população durante o lockdown. Tais aspectos evidenciam um aumento da desigualdade social vivenciada por pessoas de orientações sexuais e identidades de gênero não hegemônicas durante a pandemia.

Abstract The article presents an analysis of the impact generated by the covid-19 pandemic on the psychosocial aspects of lesbian, gay, bisexual and transgender (LGBT) people in Colombia. The methodology used was mixed, with a sequential explanatory approach, in which the qualitative results were used to explain the quantitative results and its emphasis was to interpret the relationships between the two, for this purpose the survey and discussion groups were used as research techniques. In total, 219 LGBT people participated in the study, of which 18 were lesbian, 128 gay, 36 bisexual and 37 transgender people. The most significant psychosocial impacts associated with covid-19 are related to economic aspects linked to unemployment and the decrease in family income, as well as conflicts in the family environment determined by the loss of privacy of LGBT people who must return to their homes. homes of origin; in addition to the tensions in social relationships that generate feelings of insecurity, fear and anxiety in this population due to mandatory confinement, which shows greater social inequality linked to non-hegemonic sexual orientations and gender identities that increased during the pandemic.

Resumen Este artículo presenta un análisis del impacto generado por la pandemia del covid-19 en los aspectos psicosociales de las personas lesbianas, gais, bisexuales y transgénero (LGBT) en Colombia. La metodología empleada fue mixta, con un enfoque secuencial explicativo, en el cual los resultados cualitativos se utilizaron para explicar los resultados cuantitativos y su énfasis fue interpretar las relaciones entre ambos; para tal fin se utilizaron la encuesta y los grupos de discusión como técnicas de investigación. En total, participaron en el estudio 219 personas LGBT, de las cuales 18 eran lesbianas, 128 gais, 36 bisexuales y 37 personas transgénero. Los impactos psicosociales más significativos asociados al covid-19 están relacionados con los aspectos económicos vinculados al desempleo y la disminución de los ingresos familiares, así como los conflictos en el ámbito familiar determinados por la pérdida de la privacidad de las personas LGBT que debieron regresar a sus hogares de origen; además de las tensiones en las relaciones sociales que generan sentimientos de inseguridad, temor y ansiedad en esta población debido al confinamiento obligatorio, lo cual evidencia una mayor desigualdad social vinculada a las orientaciones sexuales e identidades de género no hegemónicas que se acrecentaron en tiempos de pandemia.

A Comprehensive Review on Climate Change and Its Effects

Organizations of all life forms from species to ecosystems are impacted by the global process of Climate Change. Human civilizations are also vulnerable to changing climatic conditions. Scientific evidence shows that anthropogenic activities have resulted in global warming of 1.1 degrees Celsius. This is increasingly impacting nature so also human life everywhere. Despite efforts to adapt to the changing climate extreme events such as heatwaves over land and in the ocean droughts and flooding have caused widespread and pervasive impacts on cities and infrastructure and limit the chances of a livable future for all. In a naturally occurring process of climate change, destructive impacts have become more likely due to human interventions. The extent and magnitude of climate change impacts are larger for each additional fraction of warming than estimated so are the risks projected for the future. The impact involves severe and widespread disruptions to nature and to society, reducing our ability to grow nutritious food or provide clean drinking water. Multiple climate hazards are also occurring simultaneously with often cascading impacts. These impacts are becoming increasingly complex and challenging to manage. How these will affect nature and people depends on the speed and level. After the study of almost 100 review articles on climate change, we have shared an overview of what exactly happening to our environment and what are repercussions the future generation is going to face.

An Overview-Effects of Covid 19 Pandemic on Climate Change in India

From a public health perspective, the spread of the COVID-19 virus has become a problem. The incredible rise in disease-related infection and death rates has brought the world to a standstill in dealing with its negative consequences. This has led to a global lockdown to prevent further spread of the virus. The blockade had a huge social and economic impact. However, it also has some positive effects on the environment, especially air quality, as many research institutes point to reduced nitrogen dioxide and carbon monoxide problems in major cities (PM) around the world. Ni#trogen dioxide emissions were reduced by 20-30% in China, Italy, France and Spain, while nitrogen dioxide emissions were reduced by 30% in the United States. Compared to last year, China's air quality improved by 11.4%. NO (-77.3%), NO2 (-54.3). Compared to five years per month, 3% and carbon monoxide (-64.8%) (Signs point to a decrease) content were found during Partial shutdown in Brazil. There are about -51.84, -53.11, -17 in India 97%, -52.68, -30.35, 0.78, and -12.33 reductions in PM10, PM2 concentrations. They are SO2, NO2, CO, O3 and NH3. This article focuses on the environmental impact of closures and also discusses air pollution before and after closures in major cities around the world. Various aspects of the environment were studied and evaluated, including air, water, noise and waste management before and after closure. Therefore, this research will serve as a guide for environmentalists, leaders, and frontline activists as they look for ways to beat this disease and reduce its long-term impact on health and the environment.

Effect of Polyethylene Terephthalate Microplastics on Tomato Plant: Experimental and AI Modeling

Microplastics impacts on terrestrial ecosystem have gained attention in recent times, after about a decade of research being limited to aquatic systems. Although the impacts on soil physical characteristics and soil organisms are beginning to manifest, there is also a noticeable negative influence on plant growth and vitality. The Plant height, branches per plant, days to first fruit set, fruits per plant, fruit diameter, fruit weight (gm), and overall yield (q/hec) overall performances were explored. The tomato (Solanum lycoper­sicum Linn.) plant variety used in our study is Pusa ruby and the MPs used was Polyethylene terephthalate (PET). Different experimental parameters were also varied like MPs weight percentage (2%-5%), Nitrogen content (0.05 % -0.15%), Carbon content (1.5 %-2%), C-N ratio (14-15) and Phosphorus content (65-75). Furthermore, numerical modeling using artificial neural network (ANN) for validating the experimental results demonstrated an overall R2 value > 0.99. Our results showed that overall yield of fruit was decreased and it has also effects on different plant morphological characteristics.
