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)

In 1982 Posner and Schmidt surveyed the values of 1400 managers. The survey revealed that honesty was one of the qualities that these managers admired most in themselves. An earlier study by Brennan and Molander indicated that managers believed that honesty in communication was their greatest ethical challenge. If honesty is a prevalent value among managers then why is honesty in communication their greatest ethical challenge? This paper presents an insight into the answer to this question and into the beliefs (...) and norms of behavior that foster either a candid corporate culture or a culture that lacks candor.

We thank the commentators for the dialog and discussion they have proposed. We begin by remarking that telling and listening to stories are not an original thesis, especially if interpretive hermeneutics and phenomenology are central references. Academic and institutional settings are diverse if we consider the universe of empirical research grounded on philosophical methods and the teaching universe of practical and clinical disciplines, like psychiatry. The teaching of these disciplines frequently presents them merely as technics. A double reduction is performed: (...) the philosophical dimension of any and every technic is removed, and those who would benefit from this knowledge are presented as simple data... (shrink)

The end of the 1990s witnessed the development of evidence-based medicine, which proposed to screen, organize, and classify knowledge production in the health sciences. In this period, an increasing number of scientific publications started to incorporate the digital format and became easily accessible through the Internet. Since then, we have become used to the idea that there is a hierarchy in medical evidence. Its upper stratum, the gold standard of evidence, contains systematic reviews and meta-analyses of randomized clinical trials. The (...) base of such hierarchy contains case studies, clinical cases, and personal opinions.This knowledge hierarchy is not harmless. It has practical influences on... (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: spreto@ime.usp.brURL:https://doi.org/10.11606/T.45.2021.tde-17062021-163257.

This paper will present a review of the approaches being taken to select the management of organizations resulting from mergers and the methods employed in determining the individuals who will be terminated when there are redundancies. Current approaches are ethically questionable and poor substitutes for a meaningful performance evaluation system.

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)

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 specifically helps non-ideal social ontologists explain oppression. We offer solutions to both problems. First, we argue that Burman’s arguments for the conclusion that telic power can exist without deontic power are unsuccessful. Burman contends that this is possible because some social roles involving telic power can exist independently of institutions as sets of constitutive rules, which are––in her opinion––the source of deontic power. Burman’s arguments are not persuasive because she disregards the plausible view 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 collective recognition of the social roles of the interacting agents and, therefore, a recognition of the associated norms, the exercise of telic power does not require recognition of the relevant norms. This is why invoking telic power is particularly useful in explaining how oppression and injustice can arise. Lastly, we suggest that the relation between teleological normativity and the forms of telic power has not been fully clarified by Burman and requires a deeper analysis. (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)

This paper brings together, for the first time, Machiavelli’s interest in political and social conflicts and some ethnographical sources concerning the contemporary discovery of cannibals in the Caribbean as well as in Brazil (Tupinamba). The hypothesis is that knowledge of these sources represents a filter that allowed Machiavelli to reinterpret social clashes notably in Florentine urban context.

“Todo o poder emana do povo...” “ Todos são iguais perante a lei...” (BRASIL, 1988) Estes pequenos trechos, respectivamente do Parágrafo Único do Artigo 1º e do Artigo 5º da constituição brasileira de 1988 não foram redigidos por acaso, ou porque os legisladores assim quiseram, pois acharam que soaria bem; e nem porque de fato acreditavam nisso, mesmo enquanto representantes escolhidos pelo povo, quando de sua promulgação. O Brasil como membro fundador da Organização das Nações Unidas, incorporou em sua constituição (...) diversos pontos da Declaração Universal dos Direitos Humanos (ORGANIZAÇÃO DAS NAÇÕES UNIDAS (UN), 1948). Em 1992, o Brasil se torna signatário da Convenção Americana Sobre Direitos Humanos (ORGANIZAÇÃO DOS ESTADOS AMERICANOS (OAS), 1969), (também conhecido como Pacto de San José da Costa Rica) que existia desde 1969, e que provavelmente não fora ratificado antes devido ao, vamos chamar assim, Estado de Exceção (1964 a 1985). A teoria é que estes tratados permitam uma maior igualdade entre as pessoas, se agreguem à política e às agendas de seus países signatários, e de alguma forma, tenham valor de lei ou ao menos de referência em questões legais. Em última instância, se alguma lei local não tiver como decidir por algo, recorre-se aos tratados internacionais. A ideia por trás deste artigo é analisar o viés individualista destas cartas, remetendo sua origem a Hobbes e Rousseau, mostrando a manutenção da desigualdade entre os homens. Vale ressaltar, no entanto, que seus artigos – são 30 no da ONU, e 82 no da OEA - transpassam, perpassam e unem diversas obras, de forma que fica impossível tratar de apenas um autor ou obra específica nos trechos analisados.

Smartphones abrangem várias funcionalidades – telefonia, e-mails, dispositivo de áudio e vídeo, interação por meio de aplicativos – que têm operado transformações nas formas como os sujeitos se movimentam, aprendem e habitam os centros urbanos. Inscrita no referencial dos Estudos Culturais, este artigo é resultado de uma pesquisa exploratória que problematiza os usos de smartphones e certos deslocamentos no entendimento sobre aprendizagem. Assim, dois movimentos de investigação se interligam, sendo o primeiro uma exposição sobre a emergência de smartphones, e o (...) segundo um exame das relações entre os sujeitos e um tipo de mobilidade operada por smartphones. Os resultados indicam um tipo de aprendizagem diante das telas ao estilo móvel, ensinando formas de ser sujeito na sociedade contemporânea. (shrink)

This article addresses the modern concept of sovereignty as a multivocal and conflictual semantic field, arguing for the necessity to trace its genealogy based on the structural tensions that haunt its logical framework – as well as its representations – rather than on a linear historiographic reconstruction. In particular, the scrutiny I propose aims to examine a series of exchanges that have been characterizing this concept since the beginning: the global and the European, the maritime and the territorial, the colony (...) and the state, the imperial and the proprietary. The problematic balance between ‘imperium’ and ‘dominium’ is indeed assumed here as the turning point of the rise of a sovereign power that appears to be originally rooted in the very production and governance of the global space, thus giving up all possible Eurocentric narratives of modernity. To illustrate my argument, I focus on the frontispieces to three of Thomas Hobbes’s most important books, that is, his translation of Thucydides’ Peloponnesian Wars, De Cive and Leviathan. A thorough analysis of these images enables us to understand how these lines of force traverse the very heart of modern European political concepts, along with the mirroring effects that constantly bounce their normative construction of subjectivity back and forth from the periphery to the centre and, ultimately, from the market to the state.

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)

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.

The 3sg pronouns “he” and “she” impose descriptive gender conditions (being male/female) on their referents. These conditions are standardly analysed as presuppositions (Cooper in Quantification and syntactic theory, Reidel, Dordrecht, 1983; Heim and Kratzer in Semantics in generative grammar, Blackwell, Oxford, 1998). Cooper argues that, when 3sg pronouns occur free, they have indexical presuppositions: the gender condition must be satisfied by the pronoun’s referent in the actual world. In this paper, we consider the behaviour of free 3sg pronouns in conditionals (...) and focus on cases in which the pronouns’ gender presuppositions no longer seem to be indexical and project locally instead. We compare these cases to previously reported shifty readings of indexicals in so-called “epistemic conditionals” (Santorio in Philos Rev 121(3):359–406, 2012) and propose a unified account of locally projected gender presuppositions and shifty indexicals based on the idea that indicative conditionals are Kaplanian monsters.

English summary: The relationship between Jean-Paul Sartre and the left in France and Europe has always been a tense one. This work examines the integration of the figure of Trotsky and his ideas into the broad range of Sartre's discourse and traces its importance for the development of an independent intellectual course with respect to philosophy and politics. German description: Die Beziehung zwischen Jean-Paul Sartre und der Linken in Frankreich und Europa gestaltete sich stets spannungsreich.

En partant de l’image de la servitude volontaire comme un enchantement collectif qui apparaît au début du Discours de la servitude volontaire d’Étienne de La Boétie, cet article explore la transformation que subit la notion d’enchanteur au début du XVI e siècle. Les différents contextes que cette image permet d’identifier, indiquent que le Discours s’inscrit, de manière originale, dans la longue tradition médicale sur le pouvoir des enchantements. Cette reconstruction accorde un rôle central à la figure du chef thaumaturge, dont (...) les caractéristiques sont définies par Machiavel et Pomponazzi. L’article se termine par une comparaison entre le paradigme thaumaturgique et le paradigme charismatique et s’ouvre sur une archéologie du populisme. (shrink)

O artigo versa sobre duas passagens cruciais em que toma forma o tema da comunicação entre vida humana e vida não humana: o século XVI, com Michel de Montaigne (1533-1592) e Giordano Bruno (1548-1600), e o século XVIII, com Jean-Jacques Rous-seau (1712-1778), o qual se inspira directamente nos Essais. O artigo mostra até que ponto a ética de Montaigne se concentra sobre a escuta da natureza imanente a cada indivíduo, comportando em si a ideia da solidariedade que une todos os (...) seres vivos, reconhecendo na comunicação entre a subjectividade humana e a natureza animal a primeira modalidade de identificação com a vida débil, oprimida e sofredora, a qual é condição de explicação de uma ideia de justiça "natural e universal". A piedade constitui já uma disposição para a alteridade que brota do sentimento de identificação com a vida, na sua contingência e capacidade de sofrer. O artigo mostra também até que ponto a reflexão moral de Bruno chega a uma conclusão similar, na medida em que se afasta de uma antropologia que se recusa a conceber o ser humano como centro privilegiado de sentido no universo, antes colocando o homem e o animal numa relação de reciprocidade e de copertença. Será precisamente na medida em que retoma esta elaboração antidualista que Rousseau transformará a piedade no principal eixo da moral. /// The article focuses on the two crucial moments in which the theme of communication between human life and non-human life takes form: the XVI century, with Michel de Montaigne (1533-1592) and Giordano Bruno (1548-1600), and the XVIII century, with Jean-Jacques Rousseau (1712-1778), who directly takes inspiration from the Essais. The article shows how the ethics of Montaigne is centred upon the auscultation of the nature immanent to each individual, and at the same time embraces the idea of the solidarity which connects all living beings, acknowledging in the communication between human subjectivity and the animal nature the first modality of an identification with forms of life which are weak, oppressed and suffering, as condition of explanation for an idea of justice that is both natural and universal Piety constitutes thus a disposition for the alterity which grows from the feeling of identification with life in its contingency and capacity for suffering. The article also shows to what extent Bruno's moral reflexion comes to a similar conclusion, to the extent that it distances itself from an anthropology that refuses to take the human being as a privileged centre of meaning in the universe, placing rather the human being and the animal in a relation of reciprocity and mutual belonging. It shall precisely be to the degree that he takes up this antidualistic formulation that Rousseau will transform piety into the main axis of the moral life. (shrink)

What are words? How should words be individuated? Such questions set the agenda for the metaphysics of words. Unfortunately, misunderstandings are piling up in this field. Although the discussion between Kaplan, Cappelen, Hawthorne, Lepore and others has given rise to interesting insights into many aspects of words, I contend that the debate is highly compromised by a lack of clarity about the questions in the first place. The purpose of this article is to partially clarify the debate on the metaphysics (...) of words by examining the very nature of the questions to be addressed. I shall differentiate three inquiries about words and shall provide explanations of why misunderstandings can and do arise. I claim that, in so doing, we may put the debate back on solid footing in order to rethink the real nature of words. (shrink)

The aim of the paper is resurrecting the “Demarcation Problem”, which was considered dead in a paper written by Larry Laudan in 1983. I will go through the analysis of Imre Lakatos’ thought, which represents the most mature synthesis between the fallibilism of science and the rationality of the demarcation attitude. Lakatos’ philosophical trick is directed to acknowledge the inclinations of the contemporary philosophers, to grasp the best they can offer, and to propose a more suitable philosophy of science. He (...) follows the middle path between dogmatism and skepticism: the favorite position in order to safeguard the phenomena suggesting a rational unity of the science in an “anarchic” historical period.
