Até o início da idade moderna,Deus ocupava o centro do universo.Os humanistas da renascença elaboraram uma nova imagem do mundo,cujo senhor era o homem.A natureza foi devassada e 'desencantada':uma nova aliança substituiu a antiga.Parece que se materializaram os 'não-lugares' de todas as utopias.Contudo,todas elas padeciam de grave doença:não conseguiam discernir possibilidades reais de impossibilidades.

Arts, Real-Time Video and Interactivity for Sustainability is an ongoing collaborative research project investigating how real-time video, DIY surveillance technologies and sensor data can be used as a tool for environmental awareness, activism and artistic explorations. The project consists of a series of digital contexts for aesthetic contemplation of nature and civic engagement, aiming to foster awareness and empowerment of local populations through DIY surveillance. At the core of the ARTIVIS efforts are a series of interactive installations, that make use (...) of surveillance technologies and real-time video as raw material to promote environmental awareness through the emotion generated by real-time connections with nature. Throughout the project development, the surveillance concept has been shifting from the use of surveillance technology in a centralized platform, to the idea of veillance with distributed peer-to-peer networks that can be used for science and environmental monitoring. In this paper we present the history of the ARTiVIS project, related and inspiring work, describe ongoing research work and explore the present and future challenges of appropriating surveillance technology for artistic, educational and civic engagement purposes.

Recently, it has been argued that the phenomenon of direct transfer of intermediate metabolites between adjacent enzymes, also known as metabolic channelling, would not decrease the concentration of those intermediates in the bulk solution. However, this conclusion has been drawn by extrapolation from the results of simulations with a rather restricted set of parameters. We show that, for a number of kinetic cases, the existence of metabolic channelling can decrease the size of the soluble pool of intermediates. When the enzyme(s) (...) downstream of the channel have a catalytic capacity that is large relative to the enzymes upstream of the channel, the decrease of concentration can be substantial (3 orders of magnitude).

Our goal was to explore self‐care practices among men who have sex with men in the context of Mpox in Brazil. This study used qualitative research methods, including interviews and thematic analysis, to collect and analyze data from male participants across the Brazilian territory. The narratives unveil men's perspectives on self‐care, risk reduction, and health beliefs during the Mpox pandemic. Our findings highlight a multifaceted approach to self‐care among men, encompassing hygiene, physical contact management, mask usage, skin lesion vigilance, and (...) adherence to official guidelines. Men's attitudes toward sexual behaviors emphasize the importance of reducing sexual partners, practicing safe sex, and combating misinformation through accurate information dissemination. The development of these behaviors and self‐care practices can be facilitated by nurses guided by Dorothea Orem's Self‐Care Theory, supported by patient‐centered care, with strategies to address and confront the stigma associated with the disease and provide emotional support. Thus, the study underscores the pivotal role of self‐care in mitigating infection risks, especially in the context of emerging infectious diseases. It acknowledges the impact of socio‐cultural factors and healthcare policies on men's preventive measures. However, it also recognizes limitations, such as potential bias due to stigma concerns and a nonrepresentative sample. Ultimately, the research advocates for tailored education, promotion of gender equity, and healthcare empowerment to effectively manage health risks in such contexts. (shrink)

The main goals of this study were, to test the motivational determinants of athletes perceived effort in football considering the four-stage motivational sequence at the contextual level proposed by Hierarchical Model of Intrinsic and Extrinsic Motivation: task-involving, basic psychological needs, self-determined motivation and perceived effort. The multi-group analysis across different age-groups (U15, U17, U19, U21 years) and mediation role of basic psychological needs and self-determined motivation on the task-involving climate and the perceived effort were also analysed. Two independent samples of (...) male football athletes (N= 403, N= 403), aged 13-20 were enrolled in this study. The results demonstrated that structural model provided a good fit to data for all samples under analysis, and was invariant across U17, U19, and U21. However, it was not invariant across U15 and U17, U19 and U21. Additionally, in the results from the mediation analysis, there were significant indirect effects in all samples, supporting theoretical by self-determination theory assumptions, reinforcing the importance of basic psychological needs satisfaction and behavioral regulation in the relation in analysis. The results allow concluding that when coaches promote a task-involving climate, the basic psychological needs satisfaction of athletes improves. This climate will facilitate the regulation of their behaviors towards more autonomous forms of motivation, with positive results in the perceived effort of the athletes. (shrink)

The article is a report on the World Social Forum held in Montreal, Canada in August of 2016. It reports on philosophical ideas explored by conference participants such as Boaventura de Sousa Santos, Mireille Fanon-Mendes, Helen Lauer, and Immanuel Wallerstein. It also sums up positions articulated by activists such as Brazilians Chico Whitaker and Pedro Fuentes, and reports on some of the largest activities and highlights of the gathering.

Our work is aimed at studying the optimization of a complex motor behaviour from a global perspective. First, free climbing as a sport will be briefly introduced while emphasizing in particular its psychomotor aspect called route finding. The basic question raised here is how does the optimization of a sensorimotoricity-environment system take place. The material under study is the free climber's trajectory, viewed as the signature of climbing behaviour (i.e., the spatial dimension). The concepts of learning, optimization, constraint, and degrees (...) of freedom of a system will be discussed using the synergistic approach to the study of movement (Bernstein, 1967; Kelso, 1977). Measures of a trajectory's length and convex hull can be used to define an index whose equation resembles that of an entropy. This index is a measure of the trajectory's overall complexity. Some important concepts related to the thermodynamics of curves will also be discussed. The optimization process will be studied by examining the changes in entropy over time for a set of trajectories generated during the learning of a route (ten successive repetitions of the same climb). It will be shown that the entropy of the trajectories decreases as learning progresses, that each level of expertise has its own characteristic entropy curve, and that for the subjects tested, the mean entropy of skilled climbers is lower than that of average climbers. Basing our analysis on the concepts of degrees of freedom and constraint equations, an attempt is made to relate trajectory entropy to system entropy. Based on the postulate that trajectory entropy is equal to the difference in entropy between the unconstrained and constrained system, a model of motor optimization is proposed. This model is illustrated by an entropy graph reflecting a dynamic release process. In the light of our results, two opposing views will be examined: movement construction vs. movement emergence.

Theorists, historians, and artists address the precarious futurity of the notion of the future. Not long ago, a melancholic left and a manic neoliberalism seemed to arrive at an awkward consensus: the foreclosure of futurity. Whereas the former mourned the failure of its utopian project, the latter celebrated the triumph of a global marketplace. The radical hope of realizing a singularly different, more equitable future displaced by a belief that the future had already come to pass, limiting post-historical society to (...) an uneventful life of endless accumulation. Today, amidst an abundance of neofuturisms, posthumanisms, futurologies, speculative philosophies and accelerationist scenarios, there is as well an expanding awareness of a looming planetary catastrophe driven by the extractionist logic of capitalism. Despite this return to the future, the temporal horizon of our present moment is perhaps more aptly characterized by the “shrinking future” of just-in-time production, risk management, high-frequency trading, and the futures market. In Futurity Report, theorists, historians, and artists address the precarious futurity of the notion of the future itself.

The present study analyses the relationship between human beings, society and nature from the thought of Jean-Jacques Rousseau; European thinker inserted in a vast political-anthropological tradition that seeks to understand human existence, both in its essential and relational dimensions. In this sense, Rousseau highlights a contradiction: technical and cultural development, although necessary, can also lead to the degradation of nature and the human essence. Works such as Discourse on the Sciences and Arts, Discourse on the Origin and Foundation of Inequality (...) and Reveries of a Solitary Stroller were chosen, precisely because they allow us to examine the consequences of human alienation about its relationship with the world, also demonstrating the search for harmony as the ultimate horizon of satisfaction. A critical position in the face of social relations and the need for esteem and recognition from others. In Reveries, for example, Rousseau reflects on happiness and the relationship with nature, which, if preserved, enables a refuge from social pressures and an encounter with the true “I”. It is a criticism of itself-love (amour-propre) like the search for possessions and honours; aspects that distance humanity from self-love (amour de soi) and pity for others. (shrink)

The formation of the moral point of view in Bernard Williams’ work might be understood as taking place between two central concepts: the individual and the community. It is through the tension between these two poles that some form of knowledge is acquired. In Williams’ work, the individual virtue takes the name of authenticity, and the communitarian knowledge is, importantly, ethical confidence. A philosophical peer of Williams, Alasdair MacIntyre, has dealt with the same question, although in very different ways. They (...) are usually taken to be philosophical rivals in many respects, especially regarding their political views, their views on religion and their thoughts on Aristotle. But if we look deeper into their claims, we should discover that not only do they have similar ethical concerns, as their responses to those concerns are not, in essence, as different as they seem. My purpose with this paper, however, is not to deny the important differences between the two philosophers, but rather to make conspicuous Williams’ demanding ideas on the formation of the moral point of view by (1) connecting significant portions of his work and (2) contrasting his ideas with that of a philosophical “rival,” namely by interpreting MacIntyre’s own declarations on Williams’ work. It will stand out that both philosophers’ motivation to do ethics is to grant an equilibrium between the individual conscience and the moral knowledge that is acquired within a community. (shrink)

An analysis of Jonas' thought, focusing on three major themes: technique, vulnerability and ontology of life. Hans Jonas proposes a critique of traditional ethical approaches, which have proven incapable of dealing with the complex long-term effects of technological innovations. He suggests the "Responsibility Principle" as a new ethical paradigm, centered on considering the future consequences of human actions. In this sense, Jonas emphasizes the need for future-oriented ethics, which includes the preservation of life and the environment, ensuring that technological development (...) does not compromise future generations. The relevance of the "Responsibility Principle" lies in its ability to offer an adequate response to technological transformations and the threats they pose to planetary sustainability. Jonas highlights that the power acquired by humanity over nature, due to technological advances, requires ethical reflection that goes beyond classical paradigms such as utilitarianism and Kantian ethics. He criticizes the lack of guidance in previous approaches to dealing with long-term implications, proposing an ethics that considers the impact of current actions on future generations. (shrink)

A docência figura na lista das profissões nobres e de extrema importância social, pois é responsável pela formação acadêmica de pessoas e outros profissionais. No entanto, a ação de ensinar é, igualmente, considerada na atualidade, como uma atividade extremamente estressante. Neste estudo exploratório e qualitativo objetivou-se explorar os fatores psicossociais protetivos e de risco relacionados ao trabalho docente da educação geral da rede pública em Nampula, Moçambique. Aplicou-se um roteiro de entrevista semiestruturada a 22 profissionais de educação e oito de (...) saúde mental e ocupacional de ambos os sexos, totalizando 30 participantes. As informações tratadas através de análise temática revelaram que os fatores psicossociais protetivos mais indicados são: aprendizagem mútua, ter remuneração e reconhecimento social. Pelo contrário, baixos salários, endividamento, condições de trabalho insuficientes ou inadequadas, pouco incremento salarial, irregularidade de datas de pagamento de salários, desvalorização da classe docente, alto custo de vida, precárias condições sociais e de vida das comunidades, fraca aprendizagem dos alunos, dificuldades de conciliar trabalho-família, falta de apoio familiar e isolamento social foram apontados como principais fatores de risco psicossocial. Desse modo, é pertinente de um lado melhorar os aspectos negativos mencionados e, por outro, investigar suas repercussões na saúde mental docente. (shrink)

The wide and complex range of technologies produced and used in the contemporary societies has challenged the analysis from the different fields of social sciences. In this sense, in order to elaborate a study that aim at understanding the relationship between technological progress and the ongoing institutional changes that mark the capitalist societies, we believe it is necessary to adopt an interdisciplinary approach combining methodologies from Economics and Sociology fields. Therefore, this study proposes the development of an interdisciplinary dialogue between (...) the economic sociology of Pierre Bourdieu and the evolutionary economics developed by authors such as Giovanni Dosi, Sidney Winter, Richard Nelson and Bhaven Sampat. In doing so, we intend to demonstrate that a theory guided by Marx’s historical materialism, as it is the case of evolutionary economics, can be enriched by a materialist theory of symbolic, such as that of Pierre Bourdieu. In searching the comprehension of the complementarity between material and symbolic forces, this study addresses the conflictual process surrounding the formulation of the regulatory institutions to the biotechnology sector in Brazil over the last two decades. More precisely, through a case study, we seek to demonstrate that the convergence of discourses and interests between prestigious scientific organizations and the multinational companies that control the agrobiotechnology industry has been relevant to allow this new technological paradigm to make progress. Finally, we raise some questions concerning this alliance between business and science and the conflicts that revolve around the rapid expansion of the genetically modified crops worldwide. (shrink)

Este artigo discute como os conceitos de mediação e representação se articulam na reflexão de Carl Schmitt em alguns de seus primeiros escritos e preparam o terreno para a formulação da ideia de representação política em um de seus trabalhos mais conhecidos: Teoria da Constituição. O procedimento mediante o qual se traduz uma realidade amorfa ou um coletivo em forma de representação política se atém à noção de presentificar algo ausente ou tornar visível algo invisível. Toda ideia entra no mundo (...) empírico como hóspede forasteiro e para ganhar existência ou visibilidade necessita de uma decisão soberana pela sua representação. A finalidade deste estudo é explicar o modo pelo qual ocorre este procedimento. (shrink)

RESUMO O objetivo do artigo é analisar como se constituem axiologicamente os discursos de réus do crime de feminicídio no Tribunal do Júri. Sob perspectiva da Análise Dialógica do Discurso (ADD), analisamos dois depoimentos de assassinos, colhidos no triênio 2018-2020. A partir das camadas componentes da dimensão extralinguística dos enunciados eleitos para análise, os resultados apontam: a) no cronotopo do Júri, os discursos dos réus se manifestam defensivo-vitimistas-acusativos; b) na esfera ideológica jurídica, constituem-se híbridos, íntimo-cotidianos, morais e legais; c) na (...) situação específica de interação discursiva, concretizam-se profórmico-hierárquico-bivocais, perpassados de relações dialógicas com leis. Já na dimensão linguística, estilístico e composionalmente, os assassinos discursivizam, em tensão, imagens negativas das mulheres vítimas, descritas como traidoras, enganadoras, ciumentas, histéricas, provocativas, desajustadas, agressivas, entre outras. Sobre si, constroem imagens de homens vitimados, perturbados e interpelados a agir. (shrink)

Information Retrieval systems benefit from the use of long queries containing a large volume of search-relevant information. This situation is not common, as users of such systems tend to use very short and precise queries with few keywords. In this work we propose a modification of the Latent Dirichlet Allocation (LDA) technique using data from the document collection and its vocabulary for a better representation of short queries. Additionally, a study is carried out on how the modification of the proposed (...) LDA weighted vectors increase the performance using relevant documents as feedback. The work shown in this paper is tested using three biomedical corpora (TREC Genomics 2004, TREC Genomics 2005 and OHSUMED) and one legal corpus (FIRE 2017). Results prove that the application of the proposed representation technique, as well as the feedback adjustment, clearly outperforms the baseline methods (BM25 and non-modified LDA). (shrink)

En este artículo se ensaya un análisis de los presupuestos, de las consecuencias, que entraña la concepción cartesiana del saber. Y se llega a la conclusión de que toda la reflexión de Descartes se puede leer también como una filosofía de la historia en la que está la raíz de la idea moderna (y contemporánea) de progreso.
