El artículo pretende ofrecer una visión general del exilio gallego, principalmente en América, desde 1936, incidiendo en sus características diferenciales y peculiares con respecto al conjunto del exilio republicano español. Se pasa revista, así, al peso de la imbricación entre exilio y emigración masiva, así como a las diferentes dinámicas de integración social y de interacción entre los exiliados y las colectividades de emigrantes gallegos que tuvieron lugar en los principales países de acogida.

Rho/Rac proteins constitute a subgroup of the Ras superfamily of GTP hydrolases. Although originally implicated in the control of cytoskeletal events, it is currently known that these GTPases coordinate diverse cellular functions, including cell polarity, vesicular trafficking, the cell cycle and transcriptomal dynamics. In this review, we will provide an overview on the recent advances in this field regarding the mechanism of regulation and signaling, and the roles in vivo of this important GTPase family.

The coronavirus disease 2019 pandemic is altering dynamics in academia, and people juggling remote work and domestic demands – including childcare – have felt impacts on their productivity. Female authors have faced a decrease in paper submission rates since the beginning of the pandemic period. The reasons for this decline in women’s productivity need to be further investigated. Here, we analyzed the influence of gender, parenthood and race on academic productivity during the pandemic period based on a survey answered by (...) 3,345 Brazilian academics from various knowledge areas and research institutions. Productivity was assessed by the ability to submit papers as planned and to meet deadlines during the initial period of social isolation in Brazil. The findings revealed that male academics – especially those without children – are the least affected group, whereas Black women and mothers are the most impacted groups. These impacts are likely a consequence of the well-known unequal division of domestic labor between men and women, which has been exacerbated during the pandemic. Additionally, our results highlight that racism strongly persists in academia, especially against Black women. The pandemic will have long-term effects on the career progression of the most affected groups. The results presented here are crucial for the development of actions and policies that aim to avoid further deepening the gender gap in academia. (shrink)

‘Historical thinking’ has a central role in the theory and practice of history education. At a minimum, history educators must work with a model of historical thinking if they are to formulate potential progression in students’ advance through a school history curriculum, test that progression empirically, and shape instructional experiences in order to maximize that progression. Where do they look, and where should they look, in order to construct such models? Over the past several decades, three major strands have developed, (...) one based in the empirically minded and instruction-oriented British Schools Council History Project, a second through the more philosophically oriented German field of history didactics and historical consciousness, and a third in the US. All three had roots in the historiography and philosophy of their own national traditions. Canadian history educators have been working with a pragmatic hybrid defined around six ‘historical thinking concepts.’ While this model has both been highly influential in the reform of Canadian history curricula and prompted adaptations elsewhere, there has been only minimal theoretical discussion exploring the relationship of these concepts to each other or to the three traditions which helped to shape them. This article is a contribution towards filling that gap. (shrink)

In this paper I discuss the concept of the right to the city in articulation with the concept of urban play and more specifically, the diverse body of research related with playable and playful cities. Following a brief review of these two concepts and related studies, I critically discuss the possibilities of articulating Lefebvre's radical concept of the right to the city to contemporary interventions on urban and digital play.

Aunque, para Deleuze, un empirista es capaz de seguir los desequilibrios presentes en el funcionamiento práctico de las sociedades, de guiarse en ese plano cuyas relaciones no están predeterminadas, es necesario que además pueda servirse de algún medio de orientación en ese plano móvil, representado aquí por el cuerpo de una sociedad. Deleuze extrae del cuerpo social el peso y la inmovilidad de la estructura, incapaz de pensar la lógica de esos desequilibrios, para llenarlo de líneas con cualidades desiguales, capaces (...) de movimientos diferentes. Unas son más duras, delimitando territorios aparentemente estables, otras más flexibles, produciendo siempre zonas de inestabilidad en esos territorios, siendo a veces reintegradas al equilibrio anterior, a veces apuntando a un nuevo equilibrio, o simplemente a la muerte del antiguo. Este artículo trata de explorar esa lógica de las lineas con la cual Deleuze construye otra imagen de las sociedades. (shrink)

Neste artigo, desenvolveremos algumas considerações gerais, referentes a noção de biopolítica e biopoder de Michel Foucault relacionadas com a teoria da Necropolítica, enquanto política de morte e o exercício do necropoder, proposta pelo pensador camaronês Achille Mbembe e como essa se relaciona ao fenômeno de pandemia da Covid-19. Pretendemos assim problematizar, à luz dos aportes teóricos tanto da reflexão perpetrada por Michel Foucault, a partir do conceito de Biopolítica, quanto da noção de Necropolítica proposta por Mbembe, as questões políticas e (...) éticas presentes no contexto da eclosão desta pandemia, objetivando criticar e analisar nossa atualidade política dominada por uma racionalidade neoliberal hegemônica e intensamente destrutiva, presente na forma da gestão das condições de saúde e da vida da população por parte dos Estados.

Our abstract begins with the question: what means the sentence - the life is a capital? Michel Foucault makes the question when he signalizes that the bio-power is connected to the capitalism. In this case, the question is to understand how the increase and the confiscate of wealth suppose the power’s development that captures the life strength to make them participe to the wealth creation process. What other fundamental question could be emphasized? The contemporaneous capitalism is strictly connected to method (...) of subjetictivity production. In Nascimento da biopolítica Foucault shows how the capitalism appeals to the people to construct their lives like enterprises. It refers to homo oeconomicus like a suject that considers himself as a valuable capital. We realize the human capital is managed like lives markets, through the neoliberal biogovernamentality, regulating the sujects conducts by a place of truth, the market . We propose the constitution of a new subjectivity: the homo dispensatio. Tracing the relation between the life management as a capital and the constitution of this subjectivity, we could signalize what this situation can provide from the ethical and political viewpoint.

In aiming to frame plagiarism as an academic literacy issue, this paper focuses on the strategies used by firsts years Portuguese university students, when writing from sources, along with the relationship between these strategies and the way students view themselves as readers, writers and users of sources. The study was based on 44 short summary essays written by students as well as their responses to a questionnaire and checklist on citation rules. The evaluation of the essays revealed that students often (...) use copying and patchwriting. In addition, we found that much of the time students changed the meaning of the content expressed in the source. In relation to the way students evaluated themselves, generally their view was they used appropriate strategies. The study did not reveal a relationship between perceptions of using appropriate strategies and the use of those same strategies. Nonetheless, we found an association between performance and perceptions of using copying. Perceived use of a ‘think-then-do’ strategy was also related to changing the meaning when writing from sources. Concerning school achievement, stronger students evaluated themselves as using more appropriate strategies, and those who had not previously failed school year also displayed a better knowledge of citation rules. However, we failed to find any relationship between school achievement and the use of strategies for writing from sources. The main findings of the current research point to the existence of issues concerning how to address academic literacy, findings that go beyond plagiarism and, consequently, indicate the need for pedagogical responses.

A escola é um lugar onde as crianças compartilham o espaço-tempo com seus pares, outros sujeitos que compõem seu cotidiano e, por vezes, pesquisadoras que vão a campo com suas inquietações. Para a produção deste artigo, foi utilizado como material-base o relatório de campo desenvolvido durante uma oficina realizada com crianças do 1º ano do ensino fundamental, matriculadas em uma escola municipal localizada na Zona Norte da cidade do Rio de Janeiro. A partir das falas, não falas e outras formas (...) de expressão protagonizadas por estudantes, professora e pesquisadoras, buscamos entender o lugar da palavra na elaboração de narrativas por e sobre as crianças no contexto escolar. Além dos/as autores/as do campo dos estudos da infância, apoiamo-nos em textos literários e poéticos, por fornecerem elementos que nos permitem situarmo-nos no mundo a partir de perspectivas diversas. Como exercício de reflexão sobre os movimentos e efeitos da palavra, traçamos três linhas de análise: a palavra que anseia brecha e escuta; as palavras impostas, mal endereçadas, limitantes; e, por último, as narrativas inventadas que viram de ponta-cabeça. Além de provocar educadores/as a olharem para suas práticas pedagógicas e mediações, desafiamo-nos a pensar se há espaço na escola para a expressão livre e criadora, formadora de leituras de si e da vida.

A ventilação mecânica invasiva (VMI) tem como objetivo melhorar trocas gasosas e reduzir o trabalho ventilatório de pacientes críticos. O desmame em traqueostomia é realizado usando modo ventilatório espontâneo e períodos fora da VMI de forma progressiva. O modo ventilatório utilizado pode ser, entre outros, ventilação por pressão (PSV) ou ventilação proporcional assistida (PAV). O objetivo foi comparar o uso do modo PSV e PAV no desmame de pacientes traqueostomizados. Foram recrutados 14 indivíduos, alocados em dois grupos, PSV e PAV, (...) realizaram protocolo de desmame e ao final foram avaliadas as variáveis tempo de VMI em traqueostomia, tempo de desmame ventilatório e taxas de sucesso de desmame. O grupo PAV obteve uma mediana melhor no desfecho dias de desmame, mas sem diferença estatisticamente significativa (p=0,459). Nosso estudo não sustenta o modo PAV como melhor escolha para desmame em pacientes traqueostomizados, são necessários novos estudos com tamanho amostral maior. (shrink)

Dialoguing with, but going beyond the current history of realist thought in International Relations, the article reflects on how German émigrés contributed to the reception of Realpolitik in the Anglophone political discourse in the form of political realism. It pursues the origins of the concept in mid-nineteenth-century Germany, its first reception in the US by American-born intellectuals, and by German émigrés one century later. Focusing on the work of Hans Morgenthau, it suggests that the theory of political realism stands as (...) an inheritor of Realpolitik, as a phenomenon of cultural accommodation, though not without distortions and reinterpretations. Understanding Morgenthau’s experience in broader social, political, and academic contexts throughout this reception process may help to better understand his own contribution to the scientification of realism.

O objetivo do presente artigo é analisar as relações entre a filosofia, o ofício do escritor e a tecnologia, tecendo considerações que caminharão pelo plano do atual e do atemporal. Para embasar o trabalho, autores como Nietzsche e Edgar Morin, tendo por norte a perspectiva nietzschiana de enxergar a vida e, no caso, a tecnologia, além do bem e do mal. Além disso, o diálogo com outras áreas do saber, como o xadrez, permitirá problematizar como que é possível uma simbiose (...) entre o ser humano e a tecnologia. (shrink)

Este trabalho analisa a repercussão social do cartaz do “Salão do Livro da Região Sul e Sudeste do Pará”, evento da Feira Pan-Amazônica do Livro de 2018, para compreender como o processo de resposta social (BRAGA, 2006) impôs uma mudança institucional por parte da Secretaria de Cultura do Estado. O país homenageado foi a Colômbia e a peça de divulgação destacava uma mulher negra carregando livros na cabeça, representação das palenqueras. O fato gerou repercussão nas redes sociais e na mídia (...) local e nacional. Os protestos voltaram-se contra a reiteração de uma imagem que inferioriza as mulheres negras, reproduzindo colonialidades de gênero, poder e saber. O corpuscompõe-se de postagens no Facebooke de matérias jornalísticas veiculadas em abril de 2018. Duas técnicas metodológicas foram usadas: a netnografia (RECUERO, 2012; KOZINETS, 2014) e a aplicação de um questionário online, por meio do Facebook e Whatsapp. (shrink)

O objetivo deste estudo é apresentar uma revisão sistemática da literatura acerca da aplicação de virtudes intelectuais no contexto da prática educacional. Para o levantamento dos artigos científicos foram consultadas oito bases de dados consideradas as mais relevantes devido ao rigor científico e reconhecimento da qualidade de produção. A partir dos critérios de inclusão e exclusão foram selecionados cinco artigos científicos para serem avaliados. Nos resultados obtidos foi possível verificar a escassez de produção científica na temática, especialmente no Brasil, visto (...) que as produções, em sua maioria, são internacionais. As discussões acerca do ensino de virtudes intelectuais ainda possuem muitas divergências e lacunas, o que é normal, considerando seu pouco tempo de existência. (shrink)

Metastasis is one of the clinical parameters that has a strong negative influence on the prognosis of cancer patients. In recent years, significant advances have furthered our understanding of this process at the molecular and biological levels. This paper will discuss recent discoveries relating to the earliest, intra‐tumoral stages of metastasis in cancer cells, specifically focusing on: (i) the development of metastatic traits during primary tumorigenesis; (ii) intrinsic and extrinsic cancer cell programs associated with malignant traits; (iii) the intra‐tumoral migration (...) patterns of cancer cells and the dynamic roles played by the Rho/Rac GTPases and epithelial‐mesenchymal transitions in this process; and (iv) the genetic strategies used by metastatic cancer cells to promote intra‐tumoral cell migration and their subsequent escape to peripheral tissues. Finally, the therapeutic and diagnostic relevance of this information will be discussed, as well as potential future developments. (shrink)

Experiments with cell lines have unveiled the implication of the Rho/Rac family of GTPases in cytoskeletal organization, mitogenesis, and cell migration. However, there have not been adequate animal models to investigate the role of these proteins in more physiological settings. This scenario has changed recently in the case of the T‐cell lineage after the generation of animal models for Rho/Rac family members, their regulators, and effectors. These studies have revealed the implication of these GTPases on multiple regulatory layers of T‐cells, (...) including the coordination of cytoskeletal change, activation of kinase cascades, stimulation of calcium fluxes, and the induction of gene expression. These pathways affect the transition of different T‐cell maturation stages, the positive/negative selection of thymocytes, T‐cell responses to antigens, and the homeostasis of peripheral T‐lymphocytes. Moreover, these animals have revealed interesting cross‐talks between Rho/Rac pathways and other signal transduction routes that participate in lymphocyte responses.

We present the dossier “Studies of Childhood: movements, limits and frontiers”, a theme discussed in the III Brazilian Congress Childhood Studies (CEI). The Congress was organized by members of the Department of Childhood Studies (DEDI) and the Graduate Program in Education (ProPEd) of the State University of Rio de Janeiro. The articles that compose the dossier review the debates that took place during the event in the fields of education, international relations, and ethno-racial issues. In this presentation, inspired by Mario (...) Benedetti's poem “The Bridge”, we explore the power of three words to think about childhood and the relationship we establish with children: borders, strangeness and movements. How many borders do childhood and children cross into the political, cultural, social, and biological order of life? Which movements or changes do they produce, reproduce, and spread? How to destrange childhood, in the sense of challenging the actions and discursive productions that promote exclusions of various forms? Which movements – in the field of research and in society in general – are instituted to encourage the agency of childhood? Starting from the idea that both our culture and our subjectivity are constituted in the relationship between an interior and an exterior that are placed in tension, we draw on philosophy, literature, psychoanalysis, and cultural studies to explore these questions. In this dossier, the texts compose a set that dialogues with the philosophy of childhood and goes beyond conceptual and methodological limits, in the sense of making moves to understand children and childhood through their perspectives, actions, languages and positions, in an objective and subjective form.

This paper analyses the suitability of Effective Altruism as an ethical frame for the practices of Education for Global Citizenship in the University. According to Effective Altruism, altruistic and solidary practices should be based not only on emotional decisions, but also on a rational analysis to achieve the greatest possible impact for the benefit of third parties. Simultaneously, Universities promote Education for Global Citizenship that includes the development of competencies for the application of ethical principles focused on the improvement of (...) the world as defined in the United Nations 2030 Agenda for Sustainable Development. But the breadth of development problems demands decision criteria to select those causes that can have a greater and better impact. Therefore, Effective Altruism enumerates a reasoned repertoire of decision criteria that could facilitate the application of ethical principles among university global citizenship. (shrink)

Este artigo tem com pano de fundo a controvérsia entre criacionismo e evolucionismo que ainda captura a imaginação de amplos segmentos religiosamente orientados, sobretudo nos Estados Unidos. Aqui destacamos as proposições elaboradas pela chamada Teoria do Design Inteligente (TDI). Essa teoria, que se apresenta como científica e desprovida de qualquer compromisso religioso, propõe demonstrar empiricamente que a complexidade observada na natureza, no universo e na vida, é resultante de um design genuíno, ou seja, produto de uma inteligência organizadora, e não (...) produto de processos puramente materiais e aleatórios, isto é, decorrentes do acaso, ou da seleção natural, tal como sugere o darwinismo. Neste artigo trataremos da emergência da Teoria do Design Inteligente e de seus principais argumentos, tal como elaborados por seus proponentes, estudados pelos seus analistas e confrontados pelos seus críticos, a fim de verificar se ela é considerada teoria científica ou uma variante mais sofisticada e atual do criacionismo cristão. Palavras-chave: Religião; Ciência; Criacionismo; Design Inteligente.This article has as a backdrop the controversy between creationism and evolutionism that still captures the imagination of large religious segments, especially in the USA. This text highlights the propositions drawn up by the so called Intelligent Design Theory. Such theory, which is presented as scientific and devoid of any religious commitment aims to demonstrate empirically that the complexity observed in nature, in the universe and in the life, is a the result of a genuine design. In this sense, it would be a product of an organizing intelligence and not a product of purely material and random processes resulting from chance, or from natural selection, as suggested by Darwinism. In this article, we will deal with the emergence of Intelligent Design and its main arguments, such as elaborated by its proponents, studied by its analysts and confronted by critics, to verify if it is considered a scientific theory or a more sophisticated variant of Christian creationism. Key-words: Religion; Science; Creationism; Intelligent Design. (shrink)
