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)

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)

L’obiettivo di questo saggio è quello di mostrare come i discorsi razzisti che si moltiplicano e si sovrappongono in Europa sono in buona parte legati alla impossibilità di realizzare un’identità europea, che viene costruita in maniera difensiva ed immaginaria attraverso un meccanismo di differenziazione e di inferiorizzazione dell’Altro non occidentale. Nel ricostruire alcuni meccanismi della «mitologia razzista» tesi a evidenziarne il carattere «pluridimensionale», il lavoro si concentra sugli odierni processi migratori e su aspetti della legislazione adottata in Europa al fine (...) di evidenziarne i tratti intrinsecamente discriminatori.

This introduction opens the monographic issue starting from 1968 and arriving to neoliberalism as its most articulated answer, without the claim to give a complete picture but in order to illuminate the complexity and radicality of this caesura. In this reconstruction 1968 starts well before, so that it is not possible to establish a precise starting date and place. The contestation of authority, the questioning of patriarchy, the activation of heterogeneous and often “unexpected” subjects: the fierce critique of the current (...) state of things produced a crisis of legitimacy that involves the State, society, capitalism and science. In this sense 1968 was an unaccomplished and therefore never finished revolution. (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)

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)

This article argues that a manuscript dated to the summer of 1927 by the editors of Bohr’s Collected Works was written a year earlier. The re-dating allows the conclusion that Bohr was well on his way to complementarity before his famous fight with Heisenberg over the uncertainty principle early in 1927. The literature that assumes that complementarity was Bohr’s response to Heisenberg is therefore in error. The editors of the Collected Works assigned the document the date of 1927 because it (...) refers to electron-diffraction experiments by Davisson and Germer, which were published in 1927. But as the article points out, Bohr and other leading physicists such as Max Born met Davisson in Britain in 1926 and discussed the experiments with him then. That demolished the basis of the earlier dating. Finally, the article argues that when the document takes its place between the Bohr–Kramers–Slater theory (1924) and the 1927 drafts of complementarity, everything falls neatly into place. (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.

Neural networks are widely used in systems of artificial intelligence, but due to their black box nature, they have so far evaded formal analysis to certify that they satisfy desirable properties, mainly when they perform critical tasks. In this work, we introduce methods for the formal analysis of reachability and robustness of neural networks that are modeled as rational McNaughton functions by, first, stating such properties in the language of Łukasiewicz infinitely-valued logic and, then, using the reasoning techniques of such (...) logical system. We also present a case study where we employ the proposed techniques in an actual neural network that we trained to predict whether it will rain tomorrow in Australia. (shrink)

The ESR model proposes a new theoretical perspective which incorporates the mathematical formalism of standard (Hilbert space) quantum mechanics (QM) in a noncontextual framework, reinterpreting quantum probabilities as conditional on detection instead of absolute. We have provided in some previous papers mathematical representations of the physical entities introduced by the ESR model, namely observables, properties, pure states, proper and improper mixtures, together with rules for calculating conditional and overall probabilities, and for describing transformations of states induced by measurements. We study (...) in this paper the relevant physical case of the quantum harmonic oscillator in our mathematical formalism. We reinterpret the standard quantum rules for probabilities, provide new expressions for absolute probabilities, and show how the standard state transformations must be modified according to the ESR model.

We investigate the effects that different levels of transparency may have on a simple nudge. Using an incentivized task and eliminating possible confounds due to strategic reasoning, we examine how different types of information (positive, negative, or a combination of the two) affect the impact of a nudge on behaviour in an experimental task. Our results indicate that providing reasons in favour of the nudge increases its efficacy, while warning subjects about its potential drawbacks does not significantly reduce it.

The aim of this article is to interpret the naturalist epistemological project of W. Quine from a problematic nucleus that we can identify in I. Kant, especially in the Critique of Pure Reason, which is expressed in the categories of explanation-justification, experimental psychology and transcendental philosophy. The hypothesis of our work is that the naturalization of epistemology in a psychology by Quine is possible due to a dissolution of the limits of the concepts of explanation and justification, which have in (...) Quine a translation in the notions of concept and doctrine. To account for this, (i) we will propose, in a general way, the Kantian problematic nucleus about the distinction between explanation and justification and its relationship with the experimental psychology of the 18 th century; ii) we will analyze some important texts of W. Quine where he bases the project of a naturalization of epistemology. Our focus will be to establish the relationship between concept and doctrine as translations of Quine of the concepts of explanation and justification; (iii) finally; we will describe the psychology as a new epistemology and observational statements as an expression of this epistemological turn of Quine.

This article analyses how the philosopher Piero Martinetti conceptualizes the survival of a person’s soul after death. Martinetti’s stance is strongly influenced by the philosophy of Plotinus. Martinetti shows that the relation between singularity and multiplicity is expressed in human beings as two different and complimentary perspectives: a fundamental identity in the atemporal dimension of the intelligible life of the spirit and a dynamic tension in the empiric order of the spatio-temporal becoming. Both dimensions express themselves in a finalistic way, (...) attracted from the One who operates in them as a force of harmonization and concentration. The One as Omnitudo realitatis is the cornerstone of Martinetti’s position in regards to the survival of the individual soul after death: a concentration that happens mysteriously, because it transcends the ability of the human mind to understand it – yet, it certainly happens. ≪One thing only we know: what is worth living will live.≫.

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.

The research hypothesis that we call border as method offers a fertile ground upon which to test the potentiality and the limits of the topological approach. In this article we present our hypothesis and address three questions relevant for topology. First, we ask how the topological approach can be applied within the heterogeneous space of globalization, which we argue does not obey the dialectic of inclusion and exclusion. Second, we address the claim of neutrality that is often linked to the (...) topological approach. Our point is that in mapping a space of flows and porous borders, the topological approach must be grasped in its ambivalence; it can become a tool for control as well as a tool for the expansion of freedom and equality. Finally, we argue that it is useful, perhaps even necessary, to locate the topological approach on the border, investigating concrete practices of border crossing that challenge the very possibility of a neutral mapping.

When communicating, people adapt their linguistic representations to those of their interlocutors. Previous studies have shown that this also occurs at the semantic level for vague and context-dependent terms such as quantifiers and uncertainty expressions. However, work to date has mostly focused on passive exposure to a given speaker's interpretation, without considering the possible role of active linguistic interaction. In this study, we focus on gradable adjectives big and small and develop a novel experimental paradigm that allows participants to ask (...) clarification questions to figure out their interlocutor's interpretation. We find that, when in doubt, speakers do resort to this strategy, despite its inherent cognitive cost, and that doing so results in higher semantic alignment measured in terms of communicative success. While not all question–answer pairs are equally informative, we show that speakers become better questioners as the interaction progresses. Yet, the higher semantic alignment observed when speakers are able to ask questions does not increase over time. This suggests that conversational interaction's key advantage may be to boost coordination without committing to long-term semantic updates. Our findings shed new light on the mechanisms used by speakers to achieve semantic alignment and on how language is shaped by communication. (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.

Traditionally, medical professionals have taken a paternalistic stance towards their patients and have relied on a traditional approach to medical ethics. In recent years, in Britain, however, a new ‘managerialism’ has developed in the National Health Service (the NHS). This stresses consumerism and greater patient choice and is changing the relationship between doctors and patients. This paper draws out the implications for patients. It describes the ethical characteristics of the two conflicting approaches and argues the need to stress again the (...) view of the patient as an individual person. (shrink)
