Logics for generally were introduced for handling assertions with vague notions,such as generally, most, several, etc., by generalized quantifiers, ultrafilter logic being an interesting case. Here, we show that ultrafilter logic can be faithfully embedded into a first-order theory of certain functions, called coherent. We also use generic functions (akin to Skolem functions) to enable elimination of the generalized quantifier. These devices permit using methods for classical first-order logic to reason about consequence in ultrafilter logic.

We compare fork arrow logic, an extension of arrow logic, and its natural first-order counterpart (the correspondence language) and show that both have the same expressive power. Arrow logic is a modal logic for reasoning about arrow structures, its expressive power is limited to a bounded fragment of first-order logic. Fork arrow logic is obtained by adding to arrow logic the fork modality (related to parallelism and synchronization). As a result, fork arrow logic attains the expressive power of its first-order (...) correspondence language, so both can express the same input–output behavior of processes. (shrink)

In this paper we show that the class of fork squares has a complete orthodox axiomatization in fork arrow logic (FAL). This result may be seen as an orthodox counterpart of Venema's non-orthodox axiomatization for the class of squares in arrow logic. FAL is the modal logic of fork algebras (FAs) just as arrow logic is the modal logic of relation algebras (RAs). FAs extend RAs by a binary fork operator and are axiomatized by adding three equations to RAs equational (...) axiomatization. A proper FA is an algebra of relations where the fork is induced by an injective operation coding pair formation. In contrast to RAs, FAs are representable by proper ones and their equational theory has the expressive power of full first-order logic. A square semantics (the set of arrows is U×U for some set U) for arrow logic was defined by Y. Venema. Due to the negative results about the finite axiomatizability of representable RAs, Venema provided a non-orthodox finite axiomatization for arrow logic by adding a new rule governing the applications of a difference operator. We address here the question of extending the type of relational structures to define orthodox axiomatizations for the class of squares. Given the connections between this problem and the finitization problem addressed by I. Németi, we suspect that this cannot be done by using only logical operations. The modal version of the FA equations provides an orthodox axiomatization for FAL which is complete in view of the representability of FAs. Here we review this result and carry it further to prove that this orthodox axiomatization for FAL also axiomatizes the class of fork squares. (shrink)

Também caracterizamos validadesuniversais e existenciais em termos de tautologias.

The study aimed to identify risk attitudes of users of the Food and Nutrition Unit (UAN)located in Botucatu, SP; correlate them to food safety and to observe if there were behavioral changes after indirect educational intervention. This is an exploratory qualitative analysis study, using a non-participant observation technique. Initially, we sought to identify the most common risk attitudes among users, to develop educational materials relating the conduct during self-service to the possible risks of contamination, and thus to verify if there (...) were behavioral changes. Poor hand hygiene was seen as one of the most important points to work on, as none of the diner participants performed such an attitude. It was possible to observe small changes in the behavior of some users, showing that educational measures should be applied continuously for better awareness and greater effects. (shrink)

Physical exercise is seen as the main ally for health promotion, preventing and protecting the organism from several diseases. According to WHO, there is a tendency of constant growth in the elderly population in the coming years. The regular practice of exercises by the elderly becomes relevant to minimize the deleterious effects of the aging process and to increase the fitness index. Recently, the world population started a confrontation against Corona Virus Disease (COVID-19), which is the most significant public health (...) challenge globally. Although social isolation is a reasonable measure in an attempt to stop contamination by COVID-19, this measure has limited the ability of individuals to exercise outdoors or in gyms and health clubs, which increased the risk of developing chronic illnesses related to a sedentary lifestyle. The critical point is that the recent recommendations on exercise prescription to combat the potentially harmful effects of COVID-19 failure to adequately address resistance exercise interventions as home-based exercise strategy. Thus, in this paper, we discussed the physical exercise as medicine if the training status is enough to protect the elderly against COVID-19 infection, about the role of physical activity on immunosuppression. Possible risks for COVID-19 infection, and the old training methods, such as no-load resistance training as possible resistance exercise strategies and high-intensity interval training, as new proposals of home-based exercise interventions, could perform during the current COVID-19 pandemic.

The coronavirus disease 2019 (COVID-19) pandemic has had profound effects on all aspects of society. Families were among those directly impacted by the first measures imposed by health authorities worldwide to contain the spread of the Sars-CoV-2 virus, where social distancing and mandatory quarantine were the main approaches implemented. Notably, little is yet known about how social distancing during COVID-19 has altered families' daily routines, particularly regarding music-related behaviors. The aim of this study was 2-fold: (i) to explore changes in (...) families' daily routine and caregivers' levels of well-being and stress during the COVID-19 outbreak in Brazil and (ii) to investigate whether musical behaviors of caregivers and the children under their care (aged from 3 to 6 years old) changed during social distancing. One hundred and eighty-eight caregivers residing in Brazil participated in an online cross-sectional study conducted between July and August 2020. Our findings suggest significant changes in families' dynamics during the COVID-19 outbreak, with parents (especially mothers) spending more time on childcare and a substantial decrease in caregiver's well-being. Regarding music-related behaviors, our results revealed considerable changes in caregivers' and children's musical activities at home during social distancing, including an increase in child-only musical behaviors and shared caregiver-child activities. Moreover, sociodemographic factors such as caregiver background and well-being as well as the child's disability status significantly influenced musical engagement at home during social distancing. This study captured some features of the home musical environment of middle-class families in Brazil in the first stages of social distancing restrictions during the pandemic and caregivers' role in providing an environment where musical experiences are nurtured. Further research is needed to better understand aspects such as the long-term impact of the changes of musical behaviors at home on musical parenting and families' well-being. (shrink)

Research on the effects of lying and memory is increasingly attracting empirical attention. In the current manuscript, a scientometric analysis was carried out on the mnemonic consequences of lying. This analysis took into account 70 published articles extracted from Scopus and Web of Science databases from 1998 to 2021. A scientometric analysis was conducted in order to visualize the state of the art on this line of research. Additionally, a keywords’ cluster analysis was executed to investigate the main keywords used (...) in the published papers. Based on the keywords’ cluster analysis, we identified the main aims and critical issues of the reviewed papers. The United States and the Netherlands are the two most productive countries into the effects of lying on memory. The top five authors are mainly from European countries and wrote from 6 to 15 articles. The cluster analysis detected three clusters of keywords. The critical issues of this line of research are mainly related to the generalizability of the achieved findings for real situations, a lack of a direct control of the manipulation adopted, and a need of additional measures. The current analysis provides a comprehensive overview and understanding of existing research on the effects of lying on memory and provides possible future directions of this research domain.

Recuperamos, na esteira de trabalhos apresentados e publicados nos anais das edições 38, 39 e 40 das Reuniões Anuais da Anped, textos que abordam a escola, a educação popular, seus cenários e personagens, na periferia e no campo. Textos que observam a escola que temos e que enunciam pesquisas e propostas para a aquisição e partilha de conhecimentos de forma mais horizontalizada e dialógica. São olhos e olhares para o passado com vistas ao futuro, que na presente proposta de texto (...) somos levados a pensá-los em paralelo às figuras mitológicas de Jano e Sankofa. Partindo do diálogo, passando pela compreensão da não-neutralidade das práticas, pela formação docente permanente, pelo trabalho constante com a diferença, e chegando à reflexão decolonial e contra-hegemônica, os debates presentes nos textos em questão pensam e abordam os limites e possibilidades atravessados pela escola, na tentativa de erigir uma escola mais democrática, humana e afeita à vida. O presente artigo partiu da revisão bibliográfica das publicações do GT6 nos três últimos encontros anuais (2017, 2019 e 2021), aplicando-se sobre eles filtros relativos à escola pública e à educação popular. Buscaram-se confluências, similaridades ou mesmo divergências que apontassem a emergência de um novo paradigma de educação, destoante do modelo hegemônico, afeito às virtudes de uma civilização orientada para o neoliberalismo, para a competitividade e para as necessidades do mercado. Indícios sugestivos nos levam a crer que assuntos caros à educação popular, como questões de gênero e localidade ganharam mais protagonismo, em momentos de forte ataque à escola pública e à educação progressista.

Since the later decades of the 20 th century, Brazilian psychologists have been questioning a theoretical and interventional model in educational contexts, which consider psychological phenomena apart from their cultural contexts, in order to develop an approach based on a contextualized viewpoint. Despite progress having been made in educational psychology, as a result of this critical paradigm, this area still has problems to overcome: Psychologists are becoming increasingly separate from schools, and it is now common to find psychologists who are (...) professionally unprepared to perform in this context and furthermore, school principals do not always understand the role of psychologists in educational settings. However, educational demands exist in psychologists’ daily work in a range of contexts, indicating the relevance of this field and the urgency to improve psychologists' qualifications. Considering that Brazilian professional development programs for educators and psychologists are usually restricted to technical learning, often ignoring professionals’ real needs and claims, this research aimed to develop a special type of professional development program looking at the group as a source of development, in order to rethink professional development process from within a collaborative perspective. Research data was generated from a professional development program offered for psychologists and professionals who work within educational settings. This programme involved collaborative group work and was organized and conducted in such a way as to create conditions for change. Concepts of cultural-historical theory – social situation of development, crisis and perezhivanie – were used as analytic tools for data analysis. Analysis indicated the importance of the group as a source of development through dialogue and the co-construction of new ideas and possibilities. (shrink)

O presente artigo aborda a instituição de órgãos de polícia como representantes do poder e da autoridade do Estado sob a ótica da filosofia, sobretudo no contexto do contrato social, fundamentada em revisão bibliográfica. Ainda que o homem tenha preterido sua liberdade natural em prol de uma liberdade assistida, e sendo a polícia um dos órgãos responsáveis por essa assistência, não há como afirmar que esse trabalho está correspondendo aos anseios da sociedade, sobretudo ao se analisar os índices de violência (...) que a envolvem. Nesse sentido, a sociedade vem questionando a necessidade da existência dessas instituições, muitas vezes, inclusive, pedindo sua extinção. (shrink)

The current study verified the association between cognitive process such as attention, executive functioning, and legal capacity in patients with bipolar disorder. The sample consisted of 72 participants, assorted to episodic patients, euthymic patients, and healthy controls. We used the following neuropsychological measures: subtests of the Wechsler Abbreviated Intelligence Scale : vocabulary and matrix reasoning; Continuous Performance Test ; Five Digit Test ; and Rey–Osterrieth Complex Figure. Euthymic patients expressed slower processing speed compared to HC. They tended to make more (...) errors with slightly worse discrimination, suggesting more impulsiveness. On the contrary, episodic patients showed worse discrimination, committed more omissions, were more inconsistent with regard to response speed, showed more difficulties in organizing their actions, and were more rigid. The results suggest that bipolar patients in episode express more cognitive impairments that can compromise the quality of legal capacity. These results highlight the need for more protective support for episodic BD patients regarding legal capacity. (shrink)

La democracia vista desde premisas filosóficas críticas es la forma de poder que incentiva una estrategia vigorosa que sostiene el régimen económico globalizado y enajena los derechos fundamentales. Se explica su inicio en la antigüedad griega y su resurgimiento en el siglo de las luces en Francia con Rousseau hasta anclarse en la política contemporánea como el régimen “de las mayorías” y “de la equidad socio política”. La democracia desde la modernidad se desarrolla en América Latina como régimen de una (...) ideología que incentiva la retórica demagógica, siendo capaz de encubrir los totalitarismos y las dictaduras. La democracia, régimen político, ideología de instrumento constitucional de la economía globalizada somete hoy por hoy las consciencias y acapara con fuerza las estrategias de los dispositivos de dominación y de control. Nuestro propósito es tomar partido por una posición Latinoamericana, desde un cambio de valoración subjetiva que contrarreste los mecanismos que la promueven y respaldan. Palabras clave: democracia; democracia en América Latina; desarrollo histórico; subjetivación; autonomía social. Which Democracy for Latin America?Democracy, viewed from critical philosophical premises, is the form of power that incentives a vigorous strategy supporting the globalized economical regime and alienates fundamental rights. Its beginning can be tracked to Ancient Greece, and its resurgence in France’s Century of Lights with Rousseau, ultimately settling down in contemporary politics as the regime “of majorities” and of “socio-political equity”. From Modern Times democracy unfolds in Latin America as a regime linked with an ideology which encourages demagogical rhetoric and is capable of covering up totalitarianisms and dictatorships. Democracy, as a political regime and the ideology of globalized economy, subjugates consciences and fiercely monopolizes the devices of domination and control. Our aim is to argue for a Latin American stand, stemming from a change of subjective valuation which counteracts the mechanisms that promote and support the former.

Diderot and education as State project: The Enlightenment was not only an intellectual movement, but was also expressed in politics, such as in enlightened despotism. This was the result of an alliance between philosophers in search to spread their ideas and absolutist monarchs trying to enhance their public figures. Here we explore one among many fruits of the association between Diderot and Catherine the II, Empress of Russia: the role of the State in public education, as presented in The Plan of a University. We start from a general presentation of enlightened despotism, focusing on Diderot and Catherine the Great’s relation; next, we explore the basis of public education on the XVIII century, and finally we present Diderot’s plan itself, in which the State has the role of fostering education, relying on three key aspects: unrestricted access to education, the presence of the State in the organizational and administrative structure, and the update of the curriculum.Keywords: Enlightenment; Diderot; Education.

Elizabeth A. Povinelli, Franz Boas Professor at Columbia University, is a philosopher and anthropologist who has critically engaged with Michel Foucault’s ideas as well as scholarship inspired by his works. Povinelli has been dedicated to research on colonialism within liberalism and is also a filmmaker and founding member of The Karrabing Film Collective. The film collective is part of a larger organization of Aboriginal peoples and artists living in the Australian Northern Territory that refuses ‘fantasies of sovereignty and property’.[1] As (...) Povinelli shares with us during the interview, her trajectory was constituted in the middle of the 1980s following her life-changing encounter with the elders in Belyuen in the Australian Northern Territory. In the wake of that encounter, and with urgent issues raised about indigeneity due to changes in Australian law, Povinelli has been working even closer with her Karrabing family. The changes in law both acknowledged Aboriginal peoples' rights to their territory and imposed certain ideas of identity, family and culture, producing an entanglement between rights and government. These efforts to manage differences – cultural, race, gender – are problematized and deciphered in Povinelli’s ethnographic work with a focus on how late settler liberalism has been reconfigured with novel expressions of colonialism and imperialism.

En este trabajo proponemos mostrar que las múltiples experiencias de opresión –como efecto de las imbricaciones simultáneas entre instancias de diferenciación social y relaciones de poder- tienen como reverso experiencias de lucha, organización y resistencia colectiva como formas de participación política. Para el abordaje de las desigualdades entrecruzadas y diversas formas de violencia proponemos un enfoque interseccional por su carácter multidimensional y complejo, así como por sus raíces de lucha. Para ello, en primera instancia, trazaremos genealogías políticas que permitan historizar (...) la interseccionalidad y anudarla a sus luchas y demandas fundacionales. Analizaremos en esta dirección, las experiencias de la Combahee River Collective y de laThird World Women's Alliance, organizaciones feministas negras de la década del setenta en los Estados Unidos que buscaban enfrentar las desigualdades estructurales producidas por las articulaciones entre distintos sistemas de dominación y que direccionaron su participación política antiimperialista, anticapitalista, anticolonialista y antisexista. En un segundo momento, proponemos recuperar las genealogías críticas de la interseccionalidad para repolitizar y recomplejizar la perspectiva crítica. Finalmente, proponemos subvertir los binarismos dicotómicos y excluyentes bajo los cuales se han estructurado espacios de jerarquías y privilegios; que reproducen violencias y desigualdades.

The COVID-19 outbreak required diverse strategies, such as social distancing and self-isolation, to avoid a healthcare system crisis. However, these measures have been associated with the onset or increase of anxiety and depression symptoms in the population. Music listening was previously shown to regulate emotion, consequently reducing depression symptoms. Since previous studies with Brazilian samples have already shown a high prevalence of depressive symptoms during the first confinement period, the aim of this study was threefold: (i) to compare groups with (...) severe depression symptoms and no depression in what concerns to demographic and socio-economic factors as well as symptoms of anxiety and resilience levels, (ii) to explore changes in music listening daily routine during the confinement measures by both groups (no depression and severe depression), and (iii) to investigate which were the main factors influencing both two groups to music listening during the COVID-19 pandemic. This cross-sectional study included 494 Brazilian respondents aged 18 years and above. Our online survey comprised demographics, socio-economic, and COVID-19 related questionnaires, with questions regarding music listening used during social distancing measures on which the participants rated how much each of the 41 potential reasons for listening to music changed in importance compared to the situation before the pandemic and also the evaluation of anxiety, depression, and resilience levels. The respondents with severe depression were younger and showed higher levels of anxiety symptoms and lower resilience level. Furthermore, they were increasingly likely to listen to music to feel emotionally better with the situation, to feel comfort, to forget problems, to be energetic, to decrease sad feelings, to relax, to cheer up, to forget concerns, to express feelings, to reduce anxiety, to remember better times, to relieve boredom, to mentally stimulate themselves, and to ward off stressful thoughts compared to the participants with no depression. The exploratory factor analysis (FA) identified four types of music listening functions during social distancing measures: negative mood management, cognitive functioning, positive mood management, and physical involvement, in which the participants with severe depression revealed significant differences compared to non-depressed participants for the negative mood management factor, which shows the importance of music listening to regulate their negative emotions. As a conclusion, we can argue that most of our respondents used music listening to cope with and regulate their moods during confinement, especially those who presented with severe depression symptoms.

We prove that various classical tree forcings—for instance Sacks forcing, Mathias forcing, Laver forcing, Miller forcing and Silver forcing—preserve the statement that every real has a sharp and hence analytic determinacy. We then lift this result via methods of inner model theory to obtain level-by-level preservation of projective determinacy (PD). Assuming PD, we further prove that projective generic absoluteness holds and no new equivalence classes are added to thin projective transitive relations by these forcings.

This book provides a collection of sources, many of them fragmentary and previously scattered and hard to access, for the development of Peripatetic philosophy in the later Hellenistic period and the early Roman Empire. It also supplies the background against which the first commentator on Aristotle from whom extensive material survives, Alexander of Aphrodisias (fl. c. AD 200), developed his interpretations which continue to be influential even today. Many of the passages are here translated into English for the first time, (...) including the whole of the summary of Peripatetic ethics attributed to 'Arius Didymus'. (shrink)
