COVID-19 is an acute respiratory illness with higher mortality in older adults. This condition is spread person-to-person through close contact, and among policies employed to decrease transmission are the improvement of hygiene habits and physical distancing. Although social distancing has been recognized as the best way to prevent the transmission, there are concerns that it may promote increased depression symptoms risk and anxiety, mainly in older adults. This cross-sectional study aimed to verify self-concept of social distancing in adults compared to (...) older adults. All participants, over 18 years and residents of São Paulo state, were invited to join this research study by a message application and answered an interdisciplinary questionnaire during the period from May 23 to June 23, 2020. The questions were divided into the following aspects: sociodemographic data, financial conditions, routine-related perception, perception of health, physical and emotional state, and eating habits. The younger adult group was composed of 139 participants, with a mean age of 43.15 years, and the older adult group was composed of 437 participants with a mean age of 67.59 years of both sex. Changes in routine during the period of social distance were reported by 95% of adults and 96.8% of older adults, but adults indicated more significant alterations in routine. Although there was no difference between groups for several aspects, adults revealed greater alterations in sleep quality, evacuation frequency, and more difficulty to perform daily activities at home. Further studies are necessary to follow up the impacts of social distancing among adults and older adults in different socioeconomic contexts to better understand the long-term alterations and the necessity of interventions.

In semiotics, final causation can be related to the process of determination (PAPE, 1993). From Peirce’s point of view, determination is not a causal determinism, but a delimitation of a range of possibilities. One starts from objects towards interpretants, in a process mediated by the sign, in which the dynamic object works as a force that constrains interpretants to correspond to their objects. The correspondence between object and interpretant is important because it is through a generated interpretant that the object (...) of a sign can be known. Even though this process of determination coincides with the idea of final causation, there is a certain indeterminacy in it. For Peirce (EP 2:353, 1905), vagueness and generality are two types of indeterminacy. In the terms of the phenomenological categories, vagueness is an indeterminacy of the order of firstness, generality an indeterminacy of the order of thirdness, and both, to some extent, are opposed to that which is defined, which belongs to secondness. Each aspect of the sign may vary according to the three phenomenological categories. Consequently, degrees of imprecision are added to the semiotic process, which is a determination process. Peirce asserts that the perfect precision of thought is theoretically unattainable (SS 11, 1903). Every sign is vague or general at least to some degree. In this paper, we seek to perceive degrees of indetermination and causality from an analysis of the kinds of objects and interpretants proposed by Peirce in the system of 28 sign classes. (shrink)

In the passage of time from the 1960s to the 1970s, the Brazilian artist Waldemar Cordeiro developed his first works in computer art by applying the mathematical concept of “derivative function.” Around the same time, he organized and took part in exhibitions, and composed a series of essays envisaging that the use of digital resources would become an inevitable process for the future of information reception and artistic communication. A closer look at Waldemar Cordeiro's production, both artistic and theoretical, after (...) almost 50 years of his first forays into the field of art and technology, is an excellent opportunity not only to revisit his trajectory, but to rewrite the history of digital art and our conception of it, locating Brazil and Latin America as situated centrally, not peripherally, in relation to the European and North American narratives. Drawing from theorists in the field of informational esthetics as well as scholars in the field of media such as Arlindo Machado and Vilém Flusser, this article seeks to demonstrate, through the analysis of Waldemar Cordeiro's theoretical–artistic productions, the relationship between his work, the field of cybernetics, and his utopian and social vision of artistic production.

Michel Foucault (1926-1984) ao analisar o diálogo Apologia de Sócrates de Platão afirma que Sócrates não se vale da retórica para defender-se das acusações recebidas no tribunal ateniense. Ele não faz uso de um discurso que visa a adulação do júri pela comoção e piedade. De acordo com Foucault (2009), o filósofo faz uso da fala franca (parresía) e procura examinar as acusações recebidas em busca da verdade e da promoção da justiça. Sócrates segue o conselho de seu daímon que (...) o orienta a não preparar um discurso de defesa e pratica o exame das acusações no tribunal. Sócrates age na contramão do que até então era praticado naquele espaço, colocando-se em risco de vida e sendo, posteriormente, sentenciado a pena de morte por envenenamento. (shrink)

Os signos e as classes dos signos estão entre os tópicos mais importantes do sistema filosófico de Charles S. Peirce. As 10, 28, e 66 classes de signos são classificações desenvolvidas especialmente a partir de 1903 e representam um grande refinamento da divisão fundamental de signos – ícone, índice, símbolo. Nossa abordagem aqui define uma estratégia de visualização das classificações dos signos, com especial atenção para as 10 e 66 classes de signos. O livro está dividido em duas partes: (i) (...) bases teóricas, (ii) diagramas para as classes de signos. Na Parte I (bases teóricas), são apresentadas introdutoriamente as noções fundamentais das categorias fenomenológicas, classes de signos, as tricotomias e diagramas, assim como implicações gerais de nossa abordagem, metodologia e aplicações. Na Parte II (diagramas para as classes de signos), são apresentados e discutidos os modelos das classes, propostos por Peirce e seus comentadores, incluindo uma introdução detalhadamente documental de nossos modelos, 10cubes e 3N3, diagramas dinâmicos para as classes de signos.

Criado por homens de natureza poética e, portanto, obra por excelência da imaginação, o mundo civil dos primeiros tempos poderia ser conhecido, segundo Giambattista Vico, mediante a elaboração e a adoção de um aparato metodológico-científico que estabelece os princípios dos desenvolvimentos humanos. Tal aparato consistiria na própria Ciência Nova, obra viquiana que pretende conferir legitimidade ao conhecimento histórico, tão desprestigiado pela tradição cartesiana, mesmo de tempos remotos nos quais a faculdade imaginativa excedera à razão. Trata-se, então, neste artigo, de compreender (...) o conceito de imaginação na teoria do conhecimento de Vico e as rupturas e continuidades que o filósofo estabelece com o legado cartesiano proveniente do século anterior.

In his 1903 Syllabus, Charles S. Peirce makes a distinction between icons and iconic signs, or hypoicons, and briefly introduces a division of the latter into images, diagrams, and metaphors. Peirce scholars have tried to make better sense of those concepts by understanding iconic signs in the context of the ten classes of signs described in the same Syllabus. We will argue, however, that the three kinds of hypoicons can better be understood in the context of Peirce's sixty-six classes of (...) signs. We analyze examples of hypoicons taken from the field of information design, describing them in the framework of the sixty-six classes, and discuss the consequences of those descriptions to the debate about the order of determination of the 10 trichotomies that form those classes.

The management of child protection concerns arouses strong emotions and controversies and creates ethical tensions for all concerned. This paper provides a rational analysis of some of the issues involved and suggests responses to them. The ethical and legal duties of health-care professionals are to act in the best interests of the child by safeguarding children and reporting concerns. But this may involve conflicts with parents and produce reluctance of professionals to become involved, especially in controversial types of abuse. Mandatory (...) reporting of concerns might overcome such reluctance, but may be ineffective in the face of diagnostic uncertainties. Assembly of a stronger diagnostic evidence base would seem ethically justified, but organization of the necessary case controlled studies might be problematic. Even with a comprehensive evidence base, individual diagnoses of abuse will always involve value judgements that should be underpinned by effective training and assessment of core competencies of professionals. These manoeuvres are unlikely to prevent both justified and vexatious complaints, often in relation to breaches in professional duties or concerning professional misconduct. The tendency to blame experts may have contributed to a reluctance of other professionals to become involved, despite proposals for reforms in the expert witness and court systems. Current approaches to child protection may neither promote greater understanding nor be in the best interests of children. A revised social contract for the effective protection of children could include: a duty of care that adequately addresses the primacy of the child's welfare; the acquisition of a sound evidence base; professional transparency and accountability (but with protection from malicious and vexatious complaints); and a shift emphasis towards a more inquisitorial system that embraced the principles of truth and reconciliation.

As cidades brasileiras contemporâneas possuem espaços que ora privilegiam a realização de negócios e ora a construção de cidadania. Para compreender como são ocupados destes modos se faz necessário analisar as cidades; desde sua definição, passando pelo contexto político e econômico, para então compreender seu aspecto social. Assim, este artigo busca compreender se e em que medida as características dos espaços públicos impactam no processo de construção de cidadania. Analisando por meio de observação flutuante dois espaços públicos que são duas (...) praças urbanas centrais, localizadas em duas cidades no mesmo contexto metropolitanos. Perpassa-se pelo debate regional com o intuito de evidenciar que os conflitos são equivalentes nas diversas escalas; contudo a demonstração do contexto da Região Metropolitana do Vale do Paraíba e Litoral Norte/SP, objetiva tornar evidente que as estruturas físicas locais, dos espaços públicos urbanos centrais não direcionam as relações sociais e suas disputas, mas são um meio e resultado dessas.

We outline a process, undertaken at a large tertiary children's hospital, intended to provide practical guidance and support for those involved in the management of children with life-limiting conditions. Initial discussions with representatives of clinical and support services identified communication problems and ethical dilemmas as key issues. These were further explored in multidisciplinary hospital meetings, culminating in a conference (Living Well, Dying Well) where individual perspectives - clinical, multi-faith, parental and legal - and cases were presented. Communication problems were found (...) to involve unrealistic expectations, failures of anticipation and difficulties in discussing sensitive issues, while ethical dilemmas arose from balancing burdens and benefits, clinical uncertainty, respecting autonomy and achieving equity and justice in delivery of care. An integrated service has been developed that is intended to provide clinical and spiritual care, psychosocial and ethical support, advice and mediation for children, families and staff, and to address the latter's educational and training needs.

Countries throughout the world are counting the health and socioeconomic costs of the COVID-19 pandemic, including the strategies necessary to contain it. Profound consequences from social isolation are beginning to emerge, and there is an urgency about charting a path to recovery, albeit to a ‘new normal’ that mitigates them. Children have not suffered as much from the direct effects of COVID-19 infection as older adults. Still, there is mounting evidence that their health and welfare are being adversely affected. Closure (...) of schools has been a critical component of social isolation but has a far broader impact than the diminution of educational opportunities, as important as these are. Reopening of schools is therefore essential to recovery, with some countries already tentatively implementing it. Children’s interests are vital considerations in any recovery plan, but the question remains as to how to address them within the context of how society views children; should they be regarded as pawns, pathfinders or partners in this enterprise?

Pretendo debater, neste trabalho, três pressupostos que subjazem o desenvolvimento argumentativo do ensaio: I) a ideia presente no Tratado de que os homens se guiam pelos seus afetos ou, grosso modo, que a sociabilidade é permeada por paixões que se chocam, todo o tempo, com a vontade e interesse alheios (Hume também entende, como parece ter sido o caso de Maquiavel e Shaftesbury, que a sociedade, como um corpo, expressa um humor espelhado e forjado no jogo e conflito dos afetos (...) humanos); II) a compreensão de que o onflito, as disputas, o dissenso são constitutivos do mundo político, não devendo ser encarados como males a ser extirpados; III) a tese de que a estabilidade dos governos não requer a negação e supressão das disputas, mas antes se constituinum fino equilíbrio entre polos conflitantes, equilíbrio esse que é resultante de certos artifícios humanos (a saber, da invenção, instituição e controle das leis, de um sistema jurídico capaz de mediar as disputas políticas e sociais).

This article presents some results of a research on computational strategies for the visualization of sign classification structures and sign processes. The focus of this research is the various classifications of signs described by Peirce. Two models are presented. One of them concerns specifically the 10-fold classification as described in the 1903 Syllabus (MS 540, EP 2: 289–299), while the other deals with the deep structure of Peirce’s various trichotomic classifications. The first is 10cubes, an interactive 3-D model of Peirce’s (...) 10-fold classification, as described in the Syllabus. The second is 3N3, a computer program that builds equivalent diagrams for any n-trichotomic classification of signs. We are specially interested in how a graphic design methodology, associated with computer graphic resources and techniques, can contribute to the construction of interactive models that serve as tools for the investigation of C. S. Peirce’s theory of signs. (shrink)

This study assesses the retractions of scientific articles in engineering journals indexed on the Web of Science from 1945 to 2015. The data set was built based on documents containing the keywords retracted, retraction, withdrawal, or redress. We used database exploration techniques, including Structured Query Language and analysis of variance, for data analysis. We analyzed 238 retractions published by 117 journals. The most common reason for retraction was unethical research, and higher impact factors journals tended to publish more retractions. In (...) conclusion, most of the analyzed retractions were the result of unethical research and were retracted by editors. (shrink)

OBJECTIVES: To investigate the need for hospital clinical ethics committees by studying the frequency with which ethical dilemmas arose, the perceived adequacy of the process of their resolution, and the teaching and training of staff in medical ethics. DESIGN: Interviews with individuals and three multidisciplinary teams; questionnaire to randomly selected individuals. SETTING: Two major London children's hospitals. RESULTS: Ethical dilemmas arose frequently but were resolved in a relatively unstructured fashion. Ethical concerns included: the validity of consent for investigations and treatment; (...) lack of children's involvement in consent; initiation of heroic or futile treatments; resource allocation. Staff expressed the need for a forum which would provide consultation on ethical issues, develop guidelines for good ethical practice, undertake teaching and training, and provide ethical reflection outside the acute clinical setting. CONCLUSION: Multidisciplinary, accountable and audited clinical ethics committees with predominantly advisory, practice development and educational roles could provide a valuable contribution to UK clinical practice and perhaps in other countries that have not developed hospital clinical ethics committees.

The objective of this study is to compare the quantity of citations that retracted and nonretracted articles received in engineering based on articles indexed in the Web of Science database and published between 1945 and 2015. For data analysis, the Statistical Package for the Social Sciences was used along with the Kolmogorov–Smirnov, Mann–Whitney, Tukey–Kramer tests and descriptive statistics. The data set included 238 retracted and 236 nonretracted articles, with the retracted articles cited 2,348 times and nonretracted articles cited 2,957 times. (...) The results highlight that retraction does not end citation, thus threatening scientific credibility. (shrink)

The paucity of research data to guide current paediatric practice has led to children being termed therapeutic orphans. This difficulty is especially pertinent to research in emergency situations, such as acute resuscitation or critical care, where accepted ethical standards for overall research, have historically created practical difficulties for researchers. The welcome establishment of organisations to support UK paediatric research is helping to ensure safer and more effective medications for children, however as the balance between protection and access at the heart (...) of the paediatric research ethical debate shifts to ever increasing access for researchers to children, it remains crucial to ensure the protection for these vulnerable participants. The fundamental protection for research subjects, namely their full informed consent before any recruitment, is not tenable in true emergency situations and so other approaches are warranted if standards are to be improved by human subjects research in such areas. Proxy, deferred and retrospective consent have all been advocated as solutions to this difficulty and this paper explores the ethical justification for these approaches and their utility in safeguarding children and families in emergency situations when traditional informed consent, as currently defined, cannot be obtained in the necessary time frame to enable research.

The human attempts to access, measure and organize physical phenomena have led to a manifold construction of mathematical and physical spaces. We will survey the evolution of geometries from Euclid to the Algebraic Geometry of the 20th century. The role of Persian/Arabic Algebra in this transition and its Western symbolic development is emphasized. In this relation, we will also discuss changes in the ontological attitudes toward mathematics and its applications. Historically, the encounter of geometric and algebraic perspectives enriched the mathematical (...) practices and their foundations. Yet, the collapse of Euclidean certitudes, of over 2300 years, and the crisis in the mathematical analysis of the 19th century, led to the exclusion of “geometric judgments” from the foundations of Mathematics. After the success and the limits of the logico-formal analysis, it is necessary to broaden our foundational tools and re-examine the interactions with natural sciences. In particular, the way the geometric and algebraic approaches organize knowledge is analyzed as a cross-disciplinary and cross-cultural issue and will be examined in Mathematical Physics and Biology. We finally discuss how the current notions of mathematical (phase) “space” should be revisited for the purposes of life sciences. (shrink)

This article presents the first results of a research on visual models for the classifications of semiotic processes. The main issue discussed is how a graphic design methodology, associated with computer graphics resources, may contribute to the construction of interactive models, that can be used as tools for the investigation of C. S. Peirce theory of signs. Two models are presented: the first is an interactive 3-D model of Peirce's 3-trichotomic classification; the second is a computer program that builds diagrams (...) for any n-trichotomic classification of signs, and facilitates the analysis and comparison of different hypothesis regarding their structures.

[fr] Dans les Ḫaṣā’iṣ, Ibn Ǧinnī (m. 392/1002) fait état, incidemment, d’une différenciation entre parlers arabes nomades et sédentaires, ces derniers étant caractérisés par une perte partielle de la flexion désinentielle (’i‘rāb). Dans la mesure où Ibn Ǧinnī se réfère sur ce point à une source antérieure de près de deux siècles d’une part, indique qu’il n’y a presque plus, à son époque, de bédouin au parler « châtié » (faṣīḥ, c’est-à-dire fléchi mu‘rab) d’autre part, on peut voir dans ses (...) remarques une reconnaissance implicite d’une situation de diglossie, les parlers nomades étant à l’origine de la variété haute (al-luġa al-‘arabiyya al-faṣīḥa). Cette situation est d’ailleurs révélée par une anecdote, où l’on voit un même usager, d’origine bédouine, alterner ce qu’Ibn Ǧinnī appelle « les deux manières de parler » (ǧihatā al-kalām), avec et sans flexion désinentielle. Malgré les apparences, il ne s’agit pas de sociolinguistique et d’histoire de la langue. Il s’agit de théorie du langage, avec l’hypothèse d’un phénomène d’entropie, liée à l’utilisation de la langue, l’utilisateur se passant, par d’autres moyens, de la flexion désinentielle, source de difficulté et d’erreurs. Il s’agit aussi et surtout d’un discours épilinguistique, conforme à l’idéologie linguistique (thèse de la faṣāḥa bédouine) et à la théologie (thèse de la « langue du Ḥiǧāz » comme al-luġa alfuṣḥā), deux thèses difficilement conciliables.
