Resumen El objetivo principal del artículo es terminar quién es el Dasein desde el aparecer del mundo en la obra de Martin Heidegger Ser y tiempo. Para ello, se plantea la posibilidad de aprehensión del horizonte del sí mismo del Dasein, en contra de los propios análisis heideggerianos sobre el uno, y, también, se muestra de qué manera la mismidad del Dasein se presupone ya en el modo de aparición del mundo-entorno a través del existenciario significatividad. La conclusión del artículo (...) intentará descubrir los posibles rendimientos fenomenológicos de la apertura del horizonte del sí-mismo del Dasein.The main goal of the paper is to determine who is the Dasein itself from the appearance of the world in the Book of Martin Heidegger Being and time. For this, it raises the possibility of understanding the horizon of the self of Dasein itself differently to Heidegger’s analysis about the they and also it shows how the Selfhood of Dasein is presupposed already in the appearance of the world-environment through the existential meaningfulness. The conclusion of this paper will try to discover the phenomenological yields of Dasein’s openness as horizon of its Selfhood. (shrink)

Resumen En este texto se intenta mostrar que la radicalización de la tesis expresada por Platón en el libro X de la República no permite "apreciar" el valor que el filósofo ateniense sabe que posee la poesía, pues ella podría ser un medio para el ejercicio reflexivo si se sirve de la sobriedad que la filosofía propone. Para realizar esta tarea es menester trazar tres puntos sobre los cuales gira este texto: primero, se ubica al lector en la discusión entre (...) poesía y filosofía para comprender el contexto de la crisis entre estos dos factores de la educación en la antigüedad griega; segundo, se aborda la crítica establecida en el libro X sobre la falta de rigor que muestran los poetas en la búsqueda del conocimiento; finalmente se vislumbra o abre una posibilidad interpretativa acerca del interés que puede tener la proposición de una "poesía filosófica" en la obra de Platón.The following text will try to show that radicalization of the thesis expressed by Plato in the book X does not allow "to "estímate" the value that the Athenian philo-sopher knows that poetry possesses, since poetry might be a means for the reflexive exercise if it takes advantage of the sobriety that philosophy proposes. To carry out this task it is necessary to define three points on which this paper will be about: first, the author will inform the reader about the old discussion among poetry and philosophy to understand the context of the crisis between these two forms of teaching; Second, criticism established in the book X on the lack of rigor in the search of knowledge that poets have will be addressed. Finally, the paper glimpses or opens an interpretive possibility about the interest that the proposition of a "philosophical poetry" can have in Plato's work. (shrink)

This paper investigates the link between the consumer perception that a company is socially oriented and the consumer intention to buy products marketed by that company. We suggest that this link exists when at least two conditions prevail: (1) the products sold by that company comply with ethical and social requirements; (2) the company has an acknowledged commitment to protect consumer rights and interests. To test these hypotheses, we conducted a survey among the clients of retail chains offering Fair Trade (...) products. The results show that socially oriented companies can successfully leverage their reputation to market products with high symbolic values. (shrink)

Emotion regulation is an umbrella term to describe interactive, goal-dependent explicit and implicit processes that are intended to help an individual manage and shift an emotional experience. The primary window for appropriate emotion regulation development occurs during the infant, toddler, and preschool years. Atypical emotion regulation development is considered a risk factor for mental health problems and has been implicated as a primary mechanism underlying childhood pathologies. Current treatments are predominantly verbal- and behavioral-based and lack the opportunity to practice in-the-moment (...) management of emotionally charged situations. There is also an absence of caregiver-child interaction in these treatment strategies. Based on behavioral and neural support for music as a therapeutic mechanism, the incorporation of intentional music experiences, facilitated by a music therapist, may be one way to address these limitations. Musical Contour Regulation Facilitation is an interactive therapist-child music-based intervention for emotion regulation development practice in preschoolers. The Musical Contour Regulation Facilitation intervention uses the deliberate contour and temporal structure of a music therapy session to mirror the changing flow of the caregiver-child interaction through the alternation of high arousal and low arousal music experiences. The purpose of this paper is to describe the Therapeutic Function of Music, a theory-based description of the structural characteristics for a music-based stimulus to musically facilitate developmentally appropriate high arousal and low arousal in-the-moment emotion regulation experiences. The Therapeutic Function of Music analysis is based on a review of the music theory, music neuroscience, and music development literature and provides a preliminary model of the structural characteristics of the music as a core component of the Musical Contour Regulation Facilitation intervention.

I propose a novel hyperintensional semantics for belief revision and a corresponding system of dynamic doxastic logic. The main goal of the framework is to reduce some of the idealisations that are common in the belief revision literature and in dynamic epistemic logic. The models of the new framework are primarily based on potentially incomplete or inconsistent collections of information, represented by situations in a situation space. I propose that by shifting the representational focus of doxastic models from belief sets (...) to collections of information, and by defining changes of beliefs as artifacts of changes of information, we can achieve a more realistic account of belief representation and belief change. The proposed dynamic operation suggests a non-classical way of changing beliefs: belief revision occurs in non-explosive environments which allow for a non-monotonic and hyperintensional belief dynamics. A logic that is sound with respect to the semantics is also provided. (shrink)

Åsa Burman has recently introduced the important notion of telic power and differentiated it from deontic power in an attempt to build a bridge between ideal and non-ideal social ontology. We find Burman’s project promising but we argue that more is to be done to make it entirely successful. First, there is a palpable tension between Burman’s claim that telic power can be ontologically independent of deontic power and her examples, which suggests that these forms of power share the same (...) basis. Second, it is not completely clear how telic power helps non-ideal social ontologists explain oppression, since Burman thinks that both forms of power are transparent to social agents. We offer solutions to both problems. First, we question the thesis that telic power can exist without deontic power. Burman contends that this is possible because some social roles involving telic power can exist independently of institutions, which are––in her opinion––the source of deontic power. Against Burman, we suggest that all social roles involve deontic power, whether or not they are institutional. Second, we argue that while the exercise of deontic power requires a mutual recognition of the social roles of the interacting agents and, therefore, an acceptance of the associated norms, the exercise of telic power does not require acceptance of the relevant norms. This is why invoking telic power is useful in explaining how oppression and injustice can arise. Lastly, we suggest that the relation between teleological normativity and telic power has not been fully clarified by Burman and requires a deeper analysis. (shrink)

Eliminative materialists argue that we can overcome the phenomenological gap between two different ways of referring to our subjective experiences – either as introspectively grasped in terms of folk psychology or as explained in neurological terms – by abandoning the pre-scientific concepts of folk psychology. However, unless these theorists can offer a plausible explanation for why the scientific view of the human mind proposed by cognitive neuroscience is so deeply counter-intuitive, this argument will remain unconvincing. In order to address the (...) difficulties involved in making the paradigm shift from folk psychology to cognitive neuroscience I briefly review the theoretical revolution that marked the transition from classical mechanics to the theory of relativity at the beginning of 20th century; identify some similarities between this paradigm shift in physics and the birth of a new scientific view of the mind; explain by means of and why neurological theories that reduce consciousness and the Self to aspects of brain dynamics appear implausible from a common sense perspective despite being sound from a scientific point of view.

We largely agree with Grimwade et al ’s1 conclusion that challenge trial participants may ethically be paid, including for risk. Here, we add further arguments, clarify some points from the perspective of economics and indicate areas where economists can support the development of a framework for ethically justifiable payment. Our arguments apply to carefully constructed and monitored controlled human infection model trials that have been appropriately reviewed and approved. Participants in medical studies perform a service. Outside the domain of research (...) participation, there is nearly universal agreement that workers providing a service should be compensated fairly, and that work involving more discomfort and risk should be compensated more generously. Accordingly, labour regulations impose floors, not caps on compensation. Caps, even if intended to protect against undue inducement, also raise concerns about illegal price-fixing that disadvantages workers. Such limits on payment for egg donors have successfully been challenged in court.i Moreover, caps on compensation may harm everyone at risk of infection, not just potential participants. Insufficient compensation may impede the recruitment of enough suitable subjects, for example, when representativeness of the subject sample is required. Delays in vaccine development not only prolong disruption of social, educational and economic activity but also lead to excess infections and deaths. Unlike paid CHIM participants, individuals exposed to such infection do not accept it voluntarily, are not compensated for it, and are unlikely to receive the level of medical supervision afforded to closely monitored CHIM participants. Payment caps can lead to attempts to circumvent the regulation. For example, many countries …. (shrink)

We compute the effect of collapse models on neutrino oscillations. The effect of the collapse is to modify the evolution of the spatial part of the wave function and we will show that this indirectly amounts to a change on the flavor components. For the analysis we use the mass proportional CSL model, and perform the calculation to second order perturbation theory. As we will show, the CSL effect is very small—mainly due to the very small mass of neutrinos—and practically (...) undetectable. (shrink)

The status of wild capture fisheries has induced many fisheries and conservation scientists to express concerns about the concept of using forage fish after reduction to fishmeal and fish oil, as feed for farmed animals, particularly in aquaculture. However, a very large quantity of forage fish is being also used untransformed (fresh or frozen) globally for other purposes, such as the pet food industry. So far, no attempts have been made to estimate this quantum, and have been omitted in previous (...) fishmeal and fish oil exploitation surveys. On the basis of recently released data on the Australian importation of fresh or frozen fish for the canned cat food industry, here we show that the estimated amount of raw fishery products directly utilized by the cat food industry equates to 2.48 million metric tonnes per year. This estimate, plus the previously reported global fishmeal consumption for the production of dry pet food suggest that 13.5% of the total 39.0 million tonnes of wild caught forage fish is used for purposes other than human food production. This study attempts to bring forth information on the direct use of fresh or frozen forage fish in the pet food sector that appears to have received little attention to this date and that needs to be considered in the global debate on the ethical nature of current practices on the use of forage fish, a limited biological resource.

Scholarly research largely converges on the argument that trust is of paramount importance to drive economic agents toward mutually satisfactory, fair, and ethically compliant behaviors. There is, however, little agreement on the meaning of trust, whose conceptualizations differ with respect to actors, relationships, behaviors, and contexts. At present, we know much better what trust does than what trust is. In this article, we present an extensive review and analysis of the most prominent articles on trust in market relationships. Using computer-aided (...) content analysis and network analysis methods, we identify key, recurring dimensions that guided the conceptualization of trust in past research, and show how trust can be developed as a multifaceted and layered construct. Our results are an important contribution to a convergence of research toward a shared and common view of the meaning of trust. This process is important to ensure the body of trust research’s internal theoretical consistency, and to provide reliable and common principles for the management of business relationships – a context in which opportunism and imperfect information may induce economic actors to cheat and stray from fair and ethically compliant behaviors.

Thagard presented a framework for conceptual change in science based on conceptual systems. Thagard challenged belief revision theorists, claiming that traditional belief-revision systems are able to model only the two most conservative types of changes in his framework, but not the more radical ones. The main aim of this work is to take up Thagard’s challenge, presenting a belief-revision-like system able to mirror radical types of conceptual change. We will do that with a conceptual revision system, i.e. a belief-revision-like system (...) that takes conceptual structures as units of revisions. We will show how our conceptual revision and contraction operations satisfy analogous of the AGM postulates at the conceptual level and are able to mimic Thagard’s radical types of conceptual change.

This book reexamines the birth of quantum mechanics, in particular examining the development of crucial and original insights of Bohr. In particular, it gives a detailed study of the development and the interpretation given to Bohr's Principle of Correspondence. It also describes the role that this principle played in guiding Bohr's research over the critical period from 1920 to 1927.

I discuss two competing theories of the progressive: the theory proposed in Parsons (1980, 1985, 1989, 1990) and the theory proposed in Landman (1992). These theories differ in more than one way. Landman regards the progressive as an intentional operator, while Parsons doesn't. Moreover, Landman and Parsons disagree on what uninflected predicates denote. For Landman, cross the street has in its denotation complete events of crossing the street; the aspectual contribution of English simple past (perfective aspect) is the identity function. (...) For Parsons, both complete and incomplete events of crossing the street can be in the denotation of the base VP; perfective aspect restricts its denotation to the events that culminate. I present a version of ParsonÕs theory that avoids the problems raised by Landman, in particular the problem posed for Parsons by creation verbs. The repaired version and Landman's theory still differ in the way they analyze uninflected verbs. The repaired version and Landman's theory still differ in the way they analyze uninflected predicates. I present evidence from Slavic languages that both theories are needed. Finally, I discuss some evidence that may favor one or the other approach to the semantics of the English progressive. (shrink)

According to the theoretical framework relating hypnosis to attention, baseline attentional functioning in highly hypnotizable individuals should be more efficient than in low hypnotizable individuals. However, previous studies did not find differences in Stroop-like tasks in which the measure indicative of the Stroop interference effect was based on response latencies. This study was designed to determine whether subjects with different levels of hypnotic susceptibility show differences in baseline attentional functioning. To assess this hypothesis, high, medium, and low hypnotizable subjects performed (...) a Stroop task designed to evaluate accuracy performance, before being subjected to hypnotic induction. Results showed that the Stroop interference effect was smaller in high hypnotizable subjects than in low hypnotizable subjects, whereas it was not different between high, and medium hypnotizable subjects. This outcome supports the notion that baseline attentional functioning is related to hypnotic susceptibility. (shrink)

In the context of propositional logics, we apply semantics modulo satisfiability—a restricted semantics which comprehends only valuations that satisfy some specific set of formulas—with the aim to efficiently solve some computational tasks. Three possible such applications are developed.We begin by studying the possibility of implicitly representing rational McNaughton functions in Łukasiewicz Infinitely-valued Logic through semantics modulo satisfiability. We theoretically investigate some approaches to such representation concept, called representation modulo satisfiability, and describe a polynomial algorithm that builds representations in the newly (...) introduced system. An implementation of the algorithm, test results and ways to randomly generate rational McNaughton functions for testing are presented. Moreover, we propose an application of such representations to the formal verification of properties of neural networks by means of the reasoning framework of Łukasiewicz Infinitely-valued Logic.Then, we move to the investigation of the satisfiability of joint probabilistic assignments to formulas of Łukasiewicz Infinitely-valued Logic, which is known to be an NP-complete problem. We provide an exact decision algorithm derived from the combination of linear algebraic methods with semantics modulo satisfiability. Also, we provide an implementation for such algorithm for which the phenomenon of phase transition is empirically detected.Lastly, we study the game theory situation of observable games, which are games that are known to reach a Nash equilibrium, however, an external observer does not know what is the exact profile of actions that occur in a specific instance; thus, such observer assigns subjective probabilities to players actions. We study the decision problem of determining if a set of these probabilistic constraints is coherent by reducing it to the problems of satisfiability of probabilistic assignments to logical formulas both in Classical Propositional Logic and Łukasiewicz Infinitely-valued Logic depending on whether only pure equilibria or also mixed equilibria are allowed. Such reductions rely upon the properties of semantics modulo satisfiability. We provide complexity and algorithmic discussion for the coherence problem and, also, for the problem of computing maximal and minimal probabilistic constraints on actions that preserves coherence.prepared by Sandro Márcio da Silva Preto.E-mail: [email protected]:https://doi.org/10.11606/T.45.2021.tde-17062021-163257.

As conclusões enfatizam a fragilidade da proposta habermasiana e destacam a maior consistência da perspectiva freireana na luta contra a opressão social.

Este texto é uma apresentação da interpretação feita por Gilles Deleuze da filosofia de Henri Bergson. Procura-se enfocar os temas que viriam a ser retomados pela filosofia deleuziana, sendo desenvolvidos em Diferença e repetição e a partir dessa obra. Dentre os mais relevantes, encontrase o tema da ontologia afirmativa, que envolve a passagem do virtual para o atual através do processo de diferenciação do ser. O ser não deixa de ter existência ao atualizar-se, mas ele diferencia a si mesmo nesse (...) processo, individuando-se como as coisas presentes na experiência. O ser é, desse modo, pré-individual e pré-subjetivo. Em Bergson, haveria a coexistência virtual de todos os graus de diferenças na duração. (shrink)

The text is a presentation of Gilles Deleuze's interpretation of Henri Bergson's philosophy. It aims at focus on subjects that deleuzean philosophy should return to, developing them in Différence et répetition and from this work. Among the most outstandings, we find the affirmative ontology subject, that involves the passage from virtual to actual through being differentiation process. Being doesn't stop to have existence by actualizing itself, but it differentiates itself in this process, being individualized as things. Being is thus pre-individual (...) and pre-subjective. In Bergson, there should be a virtual coexistence of all differences degrees in duration.Este texto é uma apresentação da interpretação feita por Gilles Deleuze da filosofia de Henri Bergson.

seguindo a linha interpretativa de Deleuze, em Diferença e repetição, o artigo apresenta como, em Aristóteles e em Platão, a diferença é de! nida desde a primazia da identidade e como Deleuze rompe com ela, ao definir a diferença em si mesma. A filosofia da diferença deleuziana se compõe a partir da apreensão da diferença como virtualidade positiva e imanente, constituinte da univocidade do ser. No mesmo movimento, ela comporta uma crítica a toda filosofia que busca subordinar a diferença à (...) representação, como em Aristóteles, em que a diferença está submetida à quádrupla raiz da identidade, da analogia, da oposição e da semelhança. Apesar disso, Deleuze explicita a noção de não-ser sem negação presente no So !sta de Platão como testemunho da potência da diferença em subverter a distinção modelo-cópia, ali onde havia um empenho em subordiná-la aos poderes da identidade e da semelhança.

Microfluidic technology – the manipulation of fluids at micrometer scales – has revolutionized many areas of synthetic biology. The bottom‐up synthesis of “minimal” cell models has traditionally suffered from poor control of assembly conditions. Giant unilamellar vesicles (GUVs) are good models of living cells on account of their size and unilamellar membrane structure. In recent years, a number of microfluidic approaches for constructing GUVs has emerged. These provide control over traditionally elusive parameters of vesicular structure, such as size, lamellarity, membrane (...) composition, and internal contents. They also address sophisticated cellular functions such as division and protein synthesis. Microfluidic techniques for GUV synthesis can broadly be categorized as continuous‐flow based approaches and droplet‐based approaches. This review presents the state‐of‐the‐art of microfluidic technology, a robust platform for recapitulating complex cellular structure and function in synthetic models of biological cells. (shrink)

O livro Paulo Freire: uma arqueologia bibliográfica é fruto de um denso esforço investigativo que reuniu pesquisadores(as) brasileiros(as) sobre o pensamento freireano, buscando analisar e evidenciar o conjunto de influências presentes em sua obra. Na forma de uma arqueologia, escava o conjunto de escritos de Freire desde o final dos anos de 1950, até as obras publicadas postumamente. Como resultado, elenca e analisa no formato de verbetes 501 presenças identificadas nos seus livros, incluindo autores e autoras, instituições, pessoas, lugares e (...) fatos históricos, proporcionando aos leitores e às leitoras um amplo panorama teórico e conceitual do seu pensamento político e pedagógico. Portanto, este livro é indicada a estudantes, pesquisadores e demais interessados em compreender a complexa e densa estrutura teórica que Paulo Freire consolidou em seus mais de 30 livros publicados. A expressão “Arqueologia bibliográfica” pretende remeter à compreensão que o próprio Paulo Freire tinha da consciência, respectivamente da conscientização, como uma construção histórica composta por complexas tramas que se relacionam de muitas formas, ora se contrapondo, ora se complementando ou confirmando, todas elas compondo um estar-no-mundo único. O livro apresenta instrumentos que auxiliam a encontrar peças e rastros deixados nas páginas por esse nosso grande educador, que inspirem olhares mais profundos e mais largos sobre a educação em nosso tempo. Com as informações sobre a bibliografia referida neste livro, cada leitor e cada leitora poderá compor com mais propriedade a sua própria narrativa sobre Paulo Freire e sua obra. (shrink)

In Italian Sign Language (LIS), when past or future time adverbs are present, the signs for verbs exhibit the same manual configurations whether the sentence reports a past event or a future event. Facts of this kind, also observed for American Sign Language (ASL) and other sign languages, have led some authors (Friedman, among others) to conclude that these languages, on a par with spoken languages like Chinese, lack grammatical tense. Neidle et al. and Jacobowitz and Stokoe have challenged this (...) view for ASL and have argued that ASL sentences contain tense markers. I present some data showing that LIS verbs inflect for tense. I argue, moreover, that the apparent lack of tense inflection when LIS past and future time adverbs are present is due to the fact that these adverbs shift the s-point and that LIS past and future tenses are absolute tenses. I provide a formal account of the LIS tense system based on these assumptions. The account is implemented in Heim’s analysis of tense. (shrink)
