Background: The new human coronavirus that leads to COVID-19 has spread rapidly around the world and has a high degree of lethality. In more severe cases, patients remain hospitalized for several days under treatment of the health team. Thus, it is important to develop and use technologies with the aim to strengthen conventional therapy by encouraging movement, physical activity, and improving cardiorespiratory fitness for patients. In this sense, therapies for exposure to virtual reality are promising and have been shown to (...) be an adequate and equivalent alternative to conventional exercise programs.Aim: This is a study protocol with the aim of comparing the conventional physical therapy intervention with the use of a non-immersive VR software during COVID-19 hospitalization.Methods: Fifty patients hospitalized with confirmed diagnosis of COVID-19 will be divided in two groups under physiotherapy treatment using conventional or VR intervention: Group A: participants with COVID-19 will start the first day of the protocol with VR tasks in the morning and then in the second period, in the afternoon, will perform the conventional exercises and Group B: participants with COVID-19 will start the first day with conventional exercises in the morning and in the second period, in the afternoon, will perform activity with VR. All participants will be evaluated with different motor and physiologic scales before and after the treatment to measure improvements.Conclusion: Considering the importance of benefits from physical activity during hospitalization, VR software shows promise as a potential mechanism for improving physical activity. The results of this study may provide new insights into hospital rehabilitation.Trial Registration:ClinicalTrials.gov, identifier: NCT04537858. Registered on 01 September 2020. (shrink)

Conditional independence tests have received special attention lately in machine learning and computational intelligence related literature as an important indicator of the relationship among the variables used by their models. In the field of probabilistic graphical models, which includes Bayesian network models, conditional independence tests are especially important for the task of learning the probabilistic graphical model structure from data. In this paper, we propose the full Bayesian significance test for tests of conditional independence for discrete datasets. The full Bayesian (...) significance test is a powerful Bayesian test for precise hypothesis, as an alternative to the frequentist’s significance tests (characterized by the calculation of the p-value).

Resumo: O presente ensaio visa a interpretar o "Poema de Sete Faces", de Carlos Drummond de Andrade. O exercício de redução fenomenológica, a ambiguidade, a percepção e o corpo próprio, entre outros conceitos da Fenomenologia da percepção, de Merleau-Ponty, orientam o trabalho de leitura, estruturado a partir dos seguintes temas: o lado gauche, a correlação eu-mundo e a primazia do olhar. Tal procedimento de leitura reúne o poema hepta-partido em três faces ou tensões fundamentais, levando em conta (...) os efeitos das imagens.: The purpose of this essay is to interpret Carlos Drummond de Andrade's Poema de Sete Faces. Phenomenological reduction, ambiguity, and corporeality, among other concepts in the Phenomenology of Perception by Merleau-Ponty, lead and structure a reading based on the following themes: the left side, the correlation between self and world, and the primacy of perception. Such a reading brings together the seven part poem and dwivides it into three aspects or fundamental tensions, taking into consideration the effects of metaphor. (shrink)

The diversity in agronomic practices being used by sugarcane producers in Brazil determines differences in economic performance and cost structure. The purpose of this study is to evaluate the cost of six systems of agronomic practices using fixed or variable rates for soil amendment, fertilizer, and defensive applications and assess the profitability of these systems at three scales of sugarcane production. We then describe the data sample related to the 2019–2020 harvest season and collected from fifty-five sugarcane producers in the (...) central-south region of Brazil. Thereafter, using a quantitative approach, a cost analysis was performed, and the cumulative frequency of the net revenue for the three scales of production (small, medium, and large), was calculated using a Monte Carlo simulation. The cost analysis indicated that fertilizer had the highest cost considering the agronomic practices adopted at the three scales of production analyzed. The cumulative frequency analysis results from the Monte Carlo simulation showed the highest net revenue per hectare for medium sugarcane producers. In addition, the presence of economies of scale was not confirmed because the lowest cost was found in small-scale sugarcane producers and the highest net revenue was obtained by medium-scale sugarcane producers.

The costs of agricultural inputs added to those of labor represent almost a third of the total cost of Brazilian sugarcane production. This study analyzes the behavior of the price per ton of sugarcane in Brazil, relating it to the main production costs of this cultivation. Twelve price indicators from January 2015 to December 2020 were evaluated. First, the data were adjusted to a multiple linear regression model to identify the significant variables on variation in the price per ton of (...) sugarcane. Then, the Monte Carlo simulation was used to measure the level of certainty of occurrence of these variables, and forecasts were obtained from the adjustment of ARIMA models. The results showed the influence of the costs of diesel oil, two agricultural pesticides, and daily laborers on the price of sugarcane, besides an increasing trend of its, providing relevant short-term projections for decision-making about investments in the agribusiness sector.

Chronic migraine is a difficult disease to diagnose, and its pathophysiology remains undefined. Its symptoms affect the quality of life and daily living tasks of the affected person, leading to momentary disability. This is a pilot, randomized, controlled, double-blind clinical trial study with female patients between 18 and 65 years old with chronic migraine. The patients underwent twelve mindfulness sessions paired with anodal transcranial direct-current stimulation over the left dorsolateral prefrontal cortex, with current intensity of 2 mA applied for 20 (...) min, three times a week for 4 weeks. In addition, 20 min of mindfulness home practices were performed by guided meditation audio files. A total of 30 participants were evaluated after the treatment, and these were subdivided into two groups—active tDCS and sham tDCS, both set to mindfulness practice. The FFMQ-BR, MIDAS, and HIT-6 questionnaires were used to evaluate the outcomes. After the treatment, the active mindfulness and tDCS group showed better results in all outcomes. The sham group also showed improvements, but with smaller effect sizes compared to the active group. The only significant difference in the intergroup analysis was the outcome evaluated by HIT-6 in the post treatment result. Our results provide the first therapeutic evidence of mindfulness practices associated with left DLPFC anodal tDCS with a consequent increase in the level of full attention and analgesic benefits in the clinical symptoms of patients with chronic migraine.

Este trabajo surge a partir de la investigación general de las técnicas hidropónicas teniendo en cuenta sus ventajas y desventajas para de esta forma poder encontrar aquel factor determinante a través de una comparación de técnicas hidropónicas que permitan clasificarlas y escoger la mejor opción que genere menos impacto ambiental negativo y demuestre ser más productivo en los entornos urbanos. Adicionalmente, un factor determinante en las ciudades es su espacio limitado por lo que la mejor opción también deberá incluir un (...) óptimo manejo del espacio que permita a casi cualquier individuo poder aplicarlos desde su entorno sin recurrir a excesivas modificaciones. Como principal resultado se escogió a la Hidroponía recirculante como método predominante por los excelentes resultados que se obtienen con relación a los demás, adicionalmente, este puede ser fácilmente aplicado en los ambientes urbanos por su versatilidad y buen manejo de recursos.

Brazilian writer Carolina Maria de Jesus (1914–1977) was born in a rural community and spent most of her life in a slum. Despite this, her literary work achieved remarkable editorial success, having its value recognized by critics and academic circles. This paper analyzes Carolina Maria de Jesus’s autobiographical narratives in the light of John Dewey’s aesthetic theory, with the purpose of investigating the factors responsible for the development of her aesthetic sensitivity – intellectual and emotional dispositions favorable to involvement with (...) artistic practices. The results suggest that Carolina Maria de Jesus’s literary skills, which express not only individual but also collective yearnings, resulted from the incentive she received to think about things that do not exist and from her relationship with people who favored the formation of a personality open to varied experiences. Such results are presented as requirements for a democratic and humanist education that aims at the flowering of aesthetic sensitivity and encourages educators and students to believe in their creative potential.

There is a death by suicide in the world every 40 seconds, and suicide is the second leading cause of death for 15–29-year-olds. Experts say that one of the best ways to prevent suicide is for those in distress to hear from people who care about them. Facebook is in a unique position—through its support for networks and friendships on the site—to help connect a person in these difficult situations with people who can support them. Connecting people with the resources (...) they need is part of Facebook’s ongoing efforts to help build a safe community inside and outside of Facebook. This article provides a brief overview of how Facebook’s work to develop suicide prevention tools started and evolved, and the ethical considerations which surfaced during the process in the form of concrete product decisions around the implementation of these tools. This article is structured into three sections. Section 1 reviews what has been done in this space and lists and briefly describes other suicide prevention apps and tools. Section 2 describes Facebook’s overall approach to suicide prevention. Here, we’ll delve first into how that approach originated and how it was influenced by the external community’s proactive interactions with Facebook, highlighting our unique position to help address the problem. Afterwards, we’ll explain how that approach evolved, describing its various stages and iterations: understanding, reactive reporting, queue prioritization, and proactive reporting. This section describes the tools and resources Facebook has developed for people who may be at risk. Particular attention is devoted to the use of ArtificiaI Intelligence and Machine Learning to detect posts or live videos where someone might be expressing thoughts of suicide. Section 3 will elaborate on the ethical questions addressed when developing our approach and when making concrete product decisions to implement our suicide prevention tools. In this last section, we’ll expound the competing values and interests that were at stake during the product development process, and how we reached ethical balances between them. (shrink)

Este artigo procura expor a crítica da filósofa Hannah Arendt (1906-1975) às concepções educacionais do Pragmatismo, em especial ao pragmatismo de John Dewey (1859-1952). Primeiramente, é exposta brevemente a teoria educacional de Hannah Arendt com base no texto A crise na educação, seu único texto eminentemente educacional. Por se articular com o todo de sua obra, faz-se também incursões na vasta obra da autora, a fim de ampliar a compreensão do sentido da educação no conjunto da filosofia e da teoria (...) política arendtiana. Posteriormente, é tratada a crítica objeto deste artigo, propriamente dita, com base numa análise do texto Democracia e Educação, de Dewey, à luz da teoria arendtiana. (shrink)

ConclusionThe common assumption that Becquerel had no special reason to study uranium compounds in his search for substances emitting penetrating radiation cannot explain (a) Becquerel's own accounts, which refer to his choice as due to “the peculiar harmonic series of bands”; (b) Becquerel's systematic test of all uranium compounds (and metallic uranium), in contrast to his neglect of other substances; and (c) Becquerel's belief in invisible phosphorescence as an explanation of the radiation emitted by uranium compounds, even after his discovery (...) that non-luminescent and metallic uranium also emit penetrating radiation.By comparing Becquerel's older studies of uranium to his radioactivity research, this paper has presented a reconstruction that can explain all of these points above. According to the historical evidence presented here, it is likely that Becquerel concentrated his attention on uranium and its compounds because the mechanical theory of luminescence opened up the possibility that, precisely in the case of uranium and its compounds, a violation of Stokes's law could occur, and penetrating short-wavelength radiation could be emitted through a special type of phosphorescence.

Este artigo questiona a dimensão crítica da democracia analisada por Sheldon S. Wolin. A partir da década de 1980, o impulso de Wolin de diagnosticar as falhas da democracia americana ao conectar o liberalismo ao totalitarismo se manifesta de uma nova maneira. Ele observa que, no processo de lutar ostensiva- mente contra o totalitarismo durante a Guerra Fria, o próprio governo americano passou a incorporar uma forma totalizante de poder. Essa crítica culmina em seu diagnóstico de uma crise do século (...) XXI: a condição neoliberal de “totalitarismo invertido”. Aqui Wolin argumenta não apenas que o sistema político americano compartilha algumas características com o totalitarismo, mas também que está começando a constituir uma nova versão do totalitarismo emergindo de dentro, e não em reação ao liberalismo. Palavras-chave: Democracia. Totalitarismo. Liberalismo. (shrink)

Neste artigo, pretendo desafiar duas teses que compõem a interpretação padrão da teoria de justiça social de Hume. Primeiro, que esse entendimento não oferece recursos conceituais sufi cientes para se esboçar uma teoria de justiça distributiva e, segundo, que essa teoria é, em princípio, indiferente a ocasionais arranjos sociais fortemente desiguais. Contrariamente, proponho aqui um esboço para uma possível teoria de justiça distributiva em Hume. Argumento, com base em evidência textual, que Hume aborda sistematicamente questões como a distribuição inicial, mudanças (...) na ordem distributiva e, finalmente, ocasionais arranjos redistributivos à luz de princípios que combinam associações imaginativas, considerações de interesse público e intuições utilitaristas.

Abstract This paper describes the early history of magnetochemistry: the search for chemical effects of magnetism in the nineteenth century. Some early researchers, such as Johann Wilhelm Ritter, attempted to reproduce with magnets the effects that had been produced by electricity and Volta’s battery. For several decades, researchers successively reported positive results and denied claims concerning the effect of magnetism in oxidation, electrolysis, reduction of metals from saline solutions, crystallisation, change of colour of vegetable tinctures and other chemical reactions. In (...) the two last decades of the nineteenth century some effects were accepted as real, and a thermodynamic theory of the influence of magnetic fields upon chemical reactions was developed. Finally, Dragomir Hurmuzescu was able to create reproducible experiments and measured the electromotive force between two electrodes, with or without the presence of magnetic fields, confirming the existence of the phenomenon and obtaining results compatible with the theoretical predictions. Afterwards, this magnetochemical effect was accepted as real, but the effect was weak and its practical importance was negligible. The subject was gradually forgotten.

Escrito em 1963, três anos depois do seminário sobre A ética da psicanálise, o texto de Jaques Lacan, Kant com Sade, possibilita férteis discussões a respeito da prática analítica. Quais os limites desta prática? Qual é a razão que a sustenta? A prática analítica é um saber, uma ética ou uma terapêutica? Quais os pressupostos que orientam a sua ação? É evidente que não dispomos de condições necessárias e suficientes para respondermos a tais perguntas no limite de um artigo, tampouco (...) temos a pretensão de fazê-lo. Entretanto, as tomaremos como bússola em busca de pistas sobre a prática analítica lacaniana e o solo em que repousa até a década de 1960. A partir do texto Kant com Sade e do Seminário VII, A ética da psicanálise, ambos escritos por Lacan, buscaremos as semelhanças e diferenças irreconciliáveis entre a lei moral kantiana, a vontade de gozo sadeana e a ética psicanalítica, apontando que é a partir das consequências práticas, efetuadas pelo Marquês de Sade, da aplicação de uma razão pura, tal qual proposta por Kant, que Lacan buscará um novo horizonte para a prática analítica não mais baseada no desejo puro. Nesse sentido, tanto o filósofo alemão Immanuel Kant quanto o escritor francês Marquês de Sade, contemporâneos dos ares da modernidade, expõem um princípio universal pelo qual a ação é valorada. Princípio cuja execução evidencia sua dimensão ética, política e, com Lacan, clínica. Nessa pista, faremos uma discussão a propósito da perversão e da melancolia como limites à prática analítica.

O termo informação ganhou relevância preponderante nas décadas finais do século passado, quando, a explosão informacional, potencializada pelas tecnologias emergentes, fez com que o seu tratamento ganhasse nova dimensão, devido ao seu ritmo cada vez mais crescente. A informação é um elemento fundamental das empresas que procuram a conquista da vantagem competitiva. Para utilizá-la de forma estratégica é importante saber que informações são adequadas, deixar as informações disponíveis e acessíveis, saber as informações relevantes, sua origem e a quem endereça-las e (...) que sua transmissão seja intensa atendendo aos níveis de pertinência desejados. Entretanto, sua utilização pode não receber a devida atenção o que acarretará prejuízos tanto a eficiência quanto à eficácia organizacional. Considerando a relevância da informação, os ambientes informacionais, bem como a importância dos fluxos de informação para as Organizações, sejam elas públicas ou privadas, desenvolve-se este ensaio procurando apresentar, refletir e a provocar outras considerações e estudos a respeito da relação entre o ambiente organizacional e o ambiente informacional. Apresenta, ainda, conceitos de conjugação dos ambientes organizacional e informacional, bem como a sua dinâmica nas Organizações. INFORMATION AND ORGANIZATIONAL ENVIRONMENTS: ESSAY ON THE DYNAMICS OF INFORMATIONAL ENVIRONMENTS IN ORGANIZATIONS AbstractThe term information gained major relevance in the final decades of the last century, when the information explosion, boosted by emerging technologies, made its treatment gain a new dimension, due to its ever-increasing pace. Information is a key part of companies seeking to gain competitive advantage. To use it in a strategically form is important to know what kind of information is suitable, make it available and accessible, know the most relevant information, its origin and to whom address it and its transmission should be intense in view of the desired pertinence levels. Meanwhile, its use might not receive the due attention, what will cause losses in both efficiency and organizational effectiveness. Considering the relevance of the information, the information environments, as well as the importance of information flows for organizations, whether they are public or private, this essay was developed seeking to present, reflect and promote other considerations and works regarding the relationship between the organizational and informational environments. It also presents concepts of mixed organizational and informational environments, as well as its dynamics in organizations. (shrink)

The work fulfill two purposes. The broad objective is to relativize the division between structuralism and its alleged overcoming or continuation, with post-structuralism. This takes place within a specific procedure: the way in which Saussure develops and precedes importante theses to Deleuze's philosophy of difference. It begins with the critic that Deleuze addresses to the structuralism of the former, as unable to grasp both the differentiation and the organization of the various forms of experience. The focus on Saussure is due (...) to the fact that Deleuze considers him a discoverer of the difference in the realm of language, although he insists on reading it in oppositive and, therefore, negative terms. A “discoverer that covers-up” what he finds, it can be said, that brings to light the differential dynamics of meaning and, at the same time, covers it with the traditional image of thought that is subordinated to identity. Next, it will be clear how this reading does not consider the true positions of the philosophy of language elaborated by Saussure, and that it must be far removed from some of his reputable heirs and followers. The conclusion is that the theory of value focused on the linguistic system precedes the differential theory of the faculties that Deleuze employs to understand each of the structures of our existence.

This work relates L. S. Vygotsky’s theory to the rhetorical and poetic pedagogy, which is a set of educational ideas and practices derived from the philosophical-educational tradition initiated by the Sophists. It is verified that the Vygotskyan concepts contribute to broaden the foundations of poetic and rhetorical pedagogy, presenting a psychology of language that integrates decorum, kairos and antilogical argumentation within aesthetic experiences; communication sustains knowledge and reflection of reality, aiming at the strengthening of the individual’s identity, the education of (...) the creative subject and the improvement of the collective. It is considered that the rhetorical and poetic character of Vygotsky’s theory encourages the contemporary school to be a space for investigation and search for creative solutions, contradicting the measurementist pedagogical tendencies that dehumanize education.

This article investigates the pervasive influence of the pharmaceutical industry in Pakistan and primarily the attitudes of the medical community toward such interactions. We used an inductive approach informed by grounded theory principles to analyze interviews and focus groups with consultants, residents, medical students, and a pharmaceutical industry representative in Karachi and Lahore, and participant-observation data from two biomedical conferences. Data were then analyzed through a deontological and teleological ethical theoretical framework. Findings highlight the reasons leading to the continuation of (...) norms including weak regulations, physicians’ expectations of receiving favors, and limited exposure to bioethics education. Recommendations for practice, policy, and research are discussed. (shrink)

An analysis of the extension of the Hawking-Penrose singularity theorem to Riemann-Cartan U4 space-times with torsion and spin density is undertaken. The minimal coupling principle in U4 is used to formulate a new expression for the convergence condition autoparallels in Einstein-Cartan theory. The Gödel model with torsion is given as an example.

Há um diálogo entre os estudos antropológicos e literários não só porque a literatura está dentro do âmbito da antropologia cultural, mas também porque a literatura de um povo reflete substancialmente os aspectos da sua cultura e sua visão de mundo. Este trabalho investiga as representações de classe, raça e relações raciais em “O Romance d'A Pedra e o Príncipe do Sangue do Vai-e-Volta”, um romance do autor brasileiro contemporâneo, Ariano Suassuna (1927). Em primeiro lugar, pretende-se demonstrar como a representação (...) de Suassuna da cultura popular reflete classe, raça e relações raciais sociais em uma área particular do Brasil, o Nordeste, tradicionalmente rural. Posteriormente, investigar como a comunicação de massa, especialmente os veículos culturais de televisão e cinema, utiliza a literatura para tentar mudar ou espalhar e perpetuar atitudes racistas e formas de pensamento. Mesmo que estudos modernos tenham mostrado que o conceito de "raça" é uma construção cultural e uma falácia, a literatura e a cultura de massa exploram identidades deliberadas com base em estereótipos recebidos. Os debates linguísticos e culturais de uma cultura e país racialmente híbrido, como o Brasil, não podem deixar de considerar os conceitos de "raça" e "grupos étnicos", pois o Brasil é um país que herdou as tipologias de classe, cor e preconceito patriarcal e agrário baseadas em colonialismo português (Ribeiro, 1995). Esses debates se refletem na cultura popular de maneiras particulares; são capturados em formas eruditas de cultura, como literatura, e são então apropriados pela mídia e televisão. As obras de Suassuna podem ser vistas como um recurso valioso deste debate, apontando para questões de assimilação ou segregação de raça e / ou poder de classe, e influência, boa ou ruim, tolerância e preconceito. Observa-se o impacto de seu trabalho não só através da literatura, mas também através dos meios de comunicação. (shrink)
