In this paper we analyze the resilience to decoherence of the Macroscopic Quantum Superpositions (MQS) generated by optimal phase-covariant quantum cloning according to two coherence criteria, both based on the concept of Bures distance in Hilbert spaces. We show that all MQS generated by this system are characterized by a high resilience to decoherence processes. This analysis is supported by the results of recent MQS experiments of N=3.5×104 particles.

Femtosecond laser microfabrication has emerged in the last decade as a powerful technique for direct inscription of low loss optical waveguides in practically any transparent dielectric substrate, showing outstanding versatility. Prototyping of new devices is made rapid, cheap and easy: optical circuits are written directly buried in the substrate, using the laser beam as an optical pen, without any need of costly masks as required by conventional photolithography. Many proof-of-principle demonstrations of integrated optics can be obtained, including splitters, directional couplers, (...) and Mach–Zehnder interferometers. Actually, the road towards applications has just been opened, and the unique capabilities of femtosecond laser micromachining will enable achievements inconceivable with other technologies. In this work, the femtosecond laser fabrication technique is discussed, together with its application to the realization of integrated photonic quantum circuits. (shrink)

After reviewing current opinions about the social function of literature in second-century BCE Rome, I focus on two controversial fragments assigned to Cato the Censor's Origines. In the first, Cato portrays the ancestors in a convivial setting as they sing the praises and the manly deeds of famous men; in the second, he gestures towards the pontifex maximus' specialized use of writing and the functioning of the tabula as a locus of memory. By drawing on the field of performance studies, (...) I identify the performative features inherent in both of these fragments and map out how these features inform the positioning of Cato in relation to the identity politics of his time, professionalism, and writing. The aim of this study is to return the Origines to its immediate socio-cultural purview, but working towards this aim will also entail a shift in perspective and a reassessment of our notions of “poetry” and “prose.” In fact, by stressing the performance dimension that underlies the genesis of the Origines as a text, this article will also expose the shortcomings inherent in the hyper-literary approaches that have been so far adopted.

What, if anything, is problematic about gentrification? This article addresses this question from the perspective of normative political theory. We argue that gentrification is problematic insofar as it involves a violation of city-dwellers’ occupancy rights. We distinguish these rights from other forms of territorial rights and discuss the different implications of the argument for urban governance. If we agree on the ultimate importance of being able to pursue one’s located life plans, the argument goes, we must also agree on limiting (...) the impact of gentrification on peoples’ lives. Limiting gentrification’s impact, however, does not entail halting processes of gentrification once and for all. (shrink)

This article proposes a cost-benefit analysis of argumentation, with the aim of highlighting the strategic considerations that govern the agent's decision to argue or not. In spite of its paramount importance, the topic of argumentative decision-making has not received substantial attention in argumentation theories so far. We offer an explanation for this lack of consideration and propose a tripartite taxonomy and detailed description of the strategic reasons considered by arguers in their decision-making: benefits, costs, and dangers. We insist that the (...) implications of acknowledging the strategic dimension of arguing are far-reaching, including promising insights on how to develop better argumentation technologies. (shrink)

Cancer research is experiencing ‘paradigm instability’, since there are two rival theories of carcinogenesis which confront themselves, namely the somatic mutation theory and the tissue organization field theory. Despite this theoretical uncertainty, a huge quantity of data is available thanks to the improvement of genome sequencing techniques. Some authors think that the development of new statistical tools will be able to overcome the lack of a shared theoretical perspective on cancer by amalgamating as many data as possible. We think instead (...) that a deeper understanding of cancer can be achieved by means of more theoretical work, rather than by merely accumulating more data. To support our thesis, we introduce the analytic view of theory development, which rests on the concept of plausibility, and make clear in what sense plausibility and probability are distinct concepts. Then, the concept of plausibility is used to point out the ineliminable role played by the epistemic subject in the development of statistical tools and in the process of theory assessment. We then move to address a central issue in cancer research, namely the relevance of computational tools developed by bioinformaticists to detect driver mutations in the debate between the two main rival theories of carcinogenesis. Finally, we briefly extend our considerations on the role that plausibility plays in evidence amalgamation from cancer research to the more general issue of the divergences between frequentists and Bayesians in the philosophy of medicine and statistics. We argue that taking into account plausibility-based considerations can lead to clarify some epistemological shortcomings that afflict both these perspectives. (shrink)

In this article we strive to provide a detailed and principled analysis of the role of beliefs in goal processing—that is, the cognitive transition that leads from a mere desire to a proper intention. The resulting model of belief-based goal processing has also relevant consequences for the analysis of intentions, and constitutes the necessary core of a constructive theory of intentions, i.e. a framework that not only analyzes what an intention is, but also explains how it becomes what it is. (...) We discuss similarities and differences between our approach and other standard accounts of intention, in particular Bratman’s planning theory. The aim here is to question and refine the conceptual foundations of many theories of intentional action: as a consequence, although our analysis is not formal in itself, it is ultimately meant to have deep consequences for formal models of intentional agency.

The aim of this article is to explore the impact of Darwinism in metaethics and dispel some of the confusion surrounding it. While the prospects for a Darwinian metaethics appear to be improving, some underlying epistemological issues remain unclear. We will focus on the so-called Evolutionary Debunking Arguments (EDAs) which, when applied in metaethics, are defined as arguments that appeal to the evolutionary origins of moral beliefs so as to undermine their epistemic justification. The point is that an epistemic disanalogy (...) can be identified in the debate on EDAs between moral beliefs and other kinds of beliefs, insofar as only the former are regarded as vulnerable to EDAs. First, we will analyze some significant debunking positions in metaethics in order to show that they do not provide adequate justification for such an epistemic disanalogy. Then, we will assess whether they can avoid the accusation of being epistemically incoherent by adopting the same evolutionary account for all kinds of beliefs. In other words, once it is argued that Darwinism has a corrosive impact on metaethics, what if its universal acid cannot be contained? (shrink)

If you utter sentence ‘Obama was born in 1961’ now, you say something true about the past. Since the past will always be such that the year 1961 has the property of being a time in which Obama was born, it seems impossible that could ever be false in a future context of utterance. We shall consider the case of a sentence about the past exactly like , but which was true when uttered a few years ago and is no (...) longer true now. On this basis, we shall conclude that the past has changed. (shrink)

Presenting the first critical analysis of Carl Schmitt's _The Nomos of the Earth_ and how it relates to the epochal changes in the international system that have risen from the collapse of the ‘Westphalian’ international order. There is an emerging recognition in political theory circles that core issues, such as order, social justice, rights, need to be studied in their global context. Schmitt’s international political thought provides a stepping stone in these related paths, offering an alternative history of international relations, (...) of the genesis, achievements and demise of the ‘Westphalian system.’ Writing at a time when he believed that the spatial, political and legal order—the nomos of the earth—had collapsed, he highlighted the advent of the modern state as the vehicle of secularization, tracing how this interstate order was able to limit and ‘rationalize and humanize’ war. Providing a large number of case studies including: global terrorism, humanitarian intervention and US hegemony, this book will give further impetus to, and expand, the nascent debate on the significance of Schmitt’s legal and political thought for international politics. _The International Political Thought of Carl Schmitt_ will be of interest to students and scholars of international relations, law and history.

Western representation of countries from the Global South implies a dichotomist view of business ethics: on the one hand, universal ethics largely reproduces commonsensical views of the South as ‘less ethical’, and on the other hand, voices from the South are often conditioned to present themselves as substantially indigenous and unambiguous to be accepted as legitimate ethical subjects. We join the growing interest in bridging this gap by drawing on studies from human geography, and ask to what extent the materiality (...) of moral dilemmas bespeaks the disputed underpinning ethical values of a given space. Drawing on Henri Lefebvre’s perspective of the production of social space, we outline and apply the idea of ‘spatial ethics’ to organizations, in order to approach the entanglement between center and periphery. We analyze organizations in favelas, which are, for many authors, territories where experiences are extreme, and poverty and violence mix with vibrant culture and ingenuity. We critically approach the field of business ethics and suggest that one way of moving beyond the North–South debate is to consider that ethics cannot be transmitted or represented in empty milieus.

The paper considers sentences in which “now” occurs in initial position and shows that the meaning they convey differs from the meaning of sentences that are otherwise identical except for “now” occurring in final position. We argue that the occurrence of “now” in initial position triggers a particular kind of modal reading for the sentence to which the adverb is prefixed. A general notion of modal forcing is proposed to provide a uniform account of this kind of reading. Armed with (...) this account, we offer a solution to two tense-modal puzzles, which have to do with fatalism and the possibility of a changing past. (shrink)

Recent work in philosophy of technology has come to bear on the question of responsibility gaps. Some authors argue that the increase in the autonomous capabilities of decision-making systems makes it impossible to properly attribute responsibility for AI-based outcomes. In this article we argue that one important, and often neglected, feature of recent debates on responsibility gaps is how this debate maps on to old debates in responsibility theory. More specifically, we suggest that one of the key questions that is (...) still at issue is the significance of the reactive attitudes, and how these ought to feature in our theorizing about responsibility. We will therefore provide a new descriptive categorization of different perspectives with respect to responsibility gaps. Such reflection can provide analytical clarity about what is at stake between the various interlocutors in this debate. The main upshot of our account is the articulation of a way to frame this ‘new’ debate by drawing on the rich intellectual history of ‘old’ concepts. By regarding the question of responsibility gaps as being concerned with questions of metaphysical priority, we see that the problem of these gaps lies not in any advanced technology, but rather in how we think about responsibility.

What the rational thing to do in the face of disagreement by an epistemic peer is has been much discussed recently. Those who think that a peer’s disagreement is itself evidence against one’s belief, as many do, are committed to a special form of epistemic dependence. If such disagreement is really evidence, it seems reasonable to take it into account and to adjust one’s belief accordingly. But then it seems that the belief one ends up with depends, in part, on (...) what someone else believes, even if one does not know why that someone believes what he does. While the practical impossibility of finding actual cases of peer disagreement has been often noted, its conceptual possibility has gone unquestioned. Here we challenge this consensus and argue, first, that, strictly speaking, peer disagreement is impossible and, second, that cases of – all-too-common – near-peer disagreement present no special puzzle and require nothing more than adhering to standard principles of sensible epistemic conduct. In particular, we argue that in such cases there is no good reason to adopt the widely accepted principle that evidence of evidence is evidence. If so, even if one takes a near-peer’s disagreement as a reason for reexamining one’s belief, one is not epistemically dependent in the sense one would be if that disagreement were evidence concerning the matter in question.

Although the sunk‐cost effect is a well‐documented psychological phenomenon in monetary investments, existing literature investigating behavioral investments (e.g., time, effort) has not replicated this effect except when such investments relate to monetary values. The current explanation for this discrepancy proposes that purely behavioral sunk‐cost effects are unlikely to be observed because they are difficult to book, track, and balance in a mental account. Conversely, we argue that, through an effort‐justification mechanism, people account for the amount of behavioral resources invested when (...) selecting an alternative, in which case they may fall prey to purely behavioral sunk‐cost effects. The results of two experiments support this prediction. Because many decisions involve behavioral investments, behavioral sunk‐cost effects should be pervasive psychological phenomena. (shrink)

This book provides a critical reflection on automated science and addresses the question whether the computational tools we developed in last decades are changing the way we humans do science. More concretely: Can machines replace scientists in crucial aspects of scientific practice? The contributors to this book rethink and refine some of the main concepts by which science is understood, drawing a fascinating picture of the developments we expect over the next decades of human-machine co-evolution. The volume covers examples from (...) various fields and areas, such as molecular biology, climate modeling, clinical medicine, and artificial intelligence. The explosion of technological tools and drivers for scientific research calls for a renewed understanding of the human character of science. This book aims precisely to contribute to such a renewed understanding of science. (shrink)

The scope and mission of the history of science have been constant objects of reflection and debate within the profession. Recently, Lorraine Daston has called for a shift of focus: from the history of science to the history of knowledge. Such a move is an attempt at broadening the field and ridding it of the contradictions deriving from its modernist myth of origin and principle of demarcation. Taking the move from a pluralistic concept of medicine, the present paper explores the (...) actual and possible contributions that a history of knowledge can offer to the history of medicine in particular. As we will argue, the history of medicine has always been a history of knowledge, but for good reasons has always stuck to the concept of medicine as its object and problem throughout the ages, including the modern, scientific one. We argue that, in the history of medicine, the demarcation between scientific and non‐scientific represents an accident, but is not foundational as in the case of natural science. Furthermore, the history of medicine programmatically played a role in at least two academic domains (history proper and medical education), adjusting historical narratives of medical knowledge to its audience. Accordingly, we underscore that the history of both science and medicine, as traditionally defined, already provides room for almost the whole spectrum of approaches to history. Moreover, their different myths of origin can, and indeed must, be included in the reflexivity of the historical gaze. We argue that the position towards a history of science, medicine, or knowledge is not a question of narrative or theory, rather, it is a question of relevance and awareness of extant contexts.

It characterizes studies in Brazilian Information Science that connect gender and/or women and the Knowledge Organization (KO). The study is characterized as exploratory, descriptive, presenting bibliographical research as a data collection procedure. The bibliographic research was carried out in the Information Science Database (BRAPCI) and in the Brazilian Digital Library of Theses and Dissertations (BDTD). 42 scientific works were analyzed, including articles, dissertations, and theses. The first publication on the subject in the literature analyzed is from 2010, highlighting its incipience, (...) considering that 58% of publications are from 2017 to the present. Considering their objectives, the research was categorized into the three dimensions of ISKO-Brazil: epistemological, applied, political, and social. 22% of the research was categorized into the epistemological dimension, 39% into the applied dimension, and 39% into the political and social dimension. The epistemological dimension of KO concerning gender presents significant challenges, but also opportunities for theoretical and methodological advances that can contribute to a fairer and more inclusive representation of knowledge. Critical analysis of the work shows that, although there is progress, it is still incipient to ensure that KO is truly inclusive and representative of diverse gender identities. (shrink)

A fenomenologia tem como objetivo analisar os momentos constitutivos de diferentes experiências, fazendo justiça às suas formas específicas de aparecimento. Ao fazer isso, ela pode tornar visíveis (e, portanto, corrigir) as suposições problemáticas consideradas válidas desde o início. Estas suposições distorcem e manipulam coerentemente os fenômenos de tal forma que os fenômenos são transformados em algo radicalmente diferente. O fenômeno do déjà vu é muito interessante, nesse sentido, por duas diferentes razões. O déjà vu é transformado em um fenômeno diferente (...) no campo da ciência cognitiva: o déjà vu é comumente entendido como um simples erro de memória. Em segundo lugar, o déjà vu implica a repetição de uma experiência única e contingente. Essa lógica de repetição não é facilmente compatível com o logos das ciências empíricas, que se concentra na identificação de relações invariantes entre termos gerais por meio de pesquisa experimental e, portanto, exige uma abordagem diferente.

We examine the Doubly Inflected Construction of Sicilian (DIC; Cardinaletti and Giusti 2001, 2003, Cruschina 2013), in which a motion verb V1 from a restricted set is followed by an event verb V2 and both verbs are inflected for the same person and tense features. The interpretation of DIC involves a complex event which behaves as a single, integrated event by linguistic tests. Based on data drawn from different sources, we argue that DIC is an asymmetrical serial verb construction (Aikhenvald (...) 2006). We propose an analysis of DIC in which V1 and V2 enter the semantic composition as lexical verbs, with V1 contributing a motion event and projecting a theme and a goal argument which are identified, respectively, with an agent and a location argument projected by V2. A morphosyntactic mechanism of feature-spread requires that the person and tense features be realized both on V1 and on V2, while, semantically, these features are interpreted only once, in a position from which they take scope over the complex predicate resulting from the combination of V1 and V2. The semantic analysis is based on an operation of event concatenation, defined over spatio-temporally contiguous events which share specific participants, and is implemented in a neo-Davidsonian framework (Parsons 1990).

Recently, approach-avoidance tendencies and visual perception biases have been increasingly studied using bistable point-light walkers (PLWs). Prior studies have found a facing-the-viewer bias when one is primed with general threat stimuli (e.g. angry faces), explained by the “error management theory”, as failing to detect a threat as approaching is riskier than the opposite. Importantly, no study has explored how disease threat – linked to the behavioural immune system – might affect this bias. This study aimed to explore whether disease-signalling cues (...) can alter how we perceive the motion direction of ambiguous PLWs. Throughout 3 experiments, participants indicated the motion direction of a bistable PLW previously primed with a control or disease-signalling stimuli – that is, face with a surgical mask (Experiment 1), sickness sound (Experiment 2), or face with a disease cue (Experiment 3). Results showed that sickness cues do not significantly modulate the perception of approach-avoidance behaviours. However, a pattern emerged in Experiments 2 and 3, suggesting that sickness stimuli led to more facing away percepts. Unlike other types of threat, this implies that disease-related threat stimuli might trigger a distinct perceptual bias, indicating a preference to avoid a possible infection source. Nonetheless, this finding warrants future investigations. (shrink)

This article aims at discussing an interesting variant of scientific realism recently proposed and defended by Sandra Mitchell (forthcoming), namely an affordances-based and pragmatist variant of scientific realism. We firstly place Mitchell’s proposal in the context of the current state of the debate over scientific realism. Secondly, we summarize the salient features of Mitchell’s proposal. Thirdly, we point out some aspects of that proposal that might require some further refinement and clarification in order to make it less prone to criticisms (...) by both realists and antirealists. More precisely, in this paper we address the following issues: 1) whether Mitchell’s proposal can be classified as a genuine form of scientific realism; 2) whether the fact that in Mitchell’s proposal figure some variants of the no miracle argument is in tension with some other of its features.

Is freedom of research protected at the constitutional level? No obvious answer can be given to this question, as European and Northern American constitutional systems are not unequivocal and the topic has not been discussed deeply enough.Looking at the constitutions of some European and Northern American countries, it is possible to immediately note that there are essentially two ways to deal with freedom of scientific research. On the one hand, in Canada and in the US, constitutions have no specific provisions (...) to protect freedom of scientific research, with the result that such freedom ends up having to be protected as a specific aspect of the wider freedom of thought and expression . On the other hand, other countries’ constitutional systems, mainly European ones, expressly recognise freedom of research and teaching arts and science. For instance, article 5 of the German Constitution states that “Art and science, research and teaching are free”, article 33 of the Italian Constitution1i establishes that “The arts and sciences as well as their teaching are free” and article 59 of the Slovenian Constitution states that “Freedom of scientific research and artistic endeavor shall be guaranteed”.Within this second group, some constitutions limit their protection to the provision of freedom of scientific research, whereas other fundamental laws engage governments in promoting and supporting it. For example, the Italian Constitution, which states that “The Republic promotes cultural development and scientific and technical research” , the Spanish Constitution, according to which “public authorities shall promote science and scientific and technical research for the benefit of general interest” and, also, the Greek Constitution, whose article 16 establishes that art, science, research and their teaching are free, and their promotion is mandatory for the State.2 It ….

No presente artigo busco apresentar o caráter moderno da filosofia de Gaston Bachelard. Tal modernidade se funda numa compreensão da ideia de homem que se pode depreender da obra do filósofo. A hipótese que se pretende defender é a de que, para além de suas reflexões epistemológicas e literárias, é o modo como sua filosofia se insere em seu tempo, estabelecendo uma relação com o presente que converge com as reflexões sobre a modernidade que encontramos em pensadores como Michel Foucault (...) e Charles Baudelaire, que permite identificá-lo como moderno. Constituída essa chave de leitura sugerimos, ao final, a ideia de que se pode reconhecer certa aura rimbaudiana no pensamento de Bachelard com um todo. (shrink)

For (S, Σ) a measurable space, let ${\cal C}_1$ and ${\cal C}_2$ be convex, weak* closed sets of probability measures on Σ. We show that if ${\cal C}_1$ ∪ ${\cal C}_2$ satisfies the Lyapunov property , then there exists a set A ∈ Σ such that minμ1∈ ${\cal C}_1$ μ1(A) > maxμ2 ∈ ${\cal C}_2$ (A). We give applications to Maxmin Expected Utility (MEU) and to the core of a lower probability.

BackgroundHeavy media use has been linked to sleep problems in children, which may also extend to the infancy period. While international parent-advisory agencies, such as the American Academy of Pediatrics, advise no screen time before 18 months, parents often do not follow this recommendation. Research on Italian infants’ early access to media is sparse, and only very few studies have investigated links with sleeping habits.MethodTo address this gap, we examined concurrent associations between parent-reported surveys of child technology use and sleeping (...) patterns. The Italian version of the 60 item Comprehensive Assessment of Family Media Exposure Survey, developed as part of a larger international study,, the Brief Screening Questionnaire for Infant Sleep Problems Sadeh, 2004) were completed online by 264 Italian parents of 8- to 36-month-olds and a subset completed the Parenting Stress Index Abidin, 1995) between April 2017 and April 2018.ResultsMore devices located in the child’s room and the more time spent watching TV or using an iPad were associated with less hours of sleep at night. Furthermore, more time spent watching TV or using a smartphone, as well as the number of devices in the room was associated with going to sleep later at night. Instrumental media use was associated with less sleep.ConclusionLike other countries, Italian infants have high levels of exposure to media, and differences in media patterns were associated with sleep patterns. Cultural factors influence both instrumental reasons for media use and sleep practices. Further research should explore how media use may serve to regulate emotion as a function of both contextual factors and individual differences. (shrink)

Riassunto: In una prospettiva naturalistica, lo studio della religione presenta subito un punto problematico: se essa è così diffusa, tanto da apparire un tratto inscritto nella natura umana, ciò significa che la religione comporta dei vantaggi adattivi o, quantomeno, significa che essa non comporta svantaggi tali da ostacolare la sopravvivenza di chi la pratica. Nel primo caso, si tratta di individuare la possibile funzione della religione, ovvero una qualche utilità che ne giustificherebbe il suo permanere nella storia umana. Alla luce (...) di un modello antropologico che vede l’identità soggettiva segnata da una fragilità ontologica, in questo articolo offriremo una particolare versione della tesi che assegna alla religione, quale byproduct, una funzione positiva, ipotizzando quella che potrebbe essere una sua utilità nella difesa dell’unità dell’autocoscienza. Sarà dunque sulla religione quale insieme di tecniche difensive del self che concentreremo la nostra indagine. Parole chiave : Ernesto De Martino; Naturalismo darwiniano; Meccanismi di difesa; Identità soggettiva; Religione Religion as a Defensive Technique for Subjective Identity: From a naturalistic perspective, the study of religion immediately leads to a problematic point: if religion is so widespread, to the extent that it seems to be a trait inscribed in human nature, then it should have adaptive advantages or, at the very least, it should not have disadvantages that would stand in the way of the survival of those who practice religion. In the former case, we need to understand the function of religion, viz. a utility it confers that may justify its persistence across human history. Against the backdrop of an anthropological model that considers subjectivity identity to be characterized by ontological fragility, this article will offer a special version of the claim that religion, viewed as a byproduct, has a positive function: we will make the hypothesis that it contributes to the defense of the unity of self-consciousness. Thus our focus will be on religion construed as a repertoire of strategies designed to protect the self. Keywords: Ernesto De Martino; Darwinian Naturalism; Defense Mechanisms; Subjective Identity; Religion. (shrink)

Synapsins I and II are a family of synaptic vesicle‐associated phosphoproteins involved in the short‐term regulation of neurotransmitter release. In this review, we discuss a working model for the molecular mechanisms by which the synapsins act. We propose that synapsin I links synaptic vesicles to actin filaments in the presynaptic nerve terminal and that these interactions are modulated by the reversible phosphorylation of synapsin I through various signal transduction pathways. The high degree of homology between the synapsins suggests that some (...) of the functional properties of synapsin I are also shared by synapsin II. (shrink)

The concentration of high-frequency controls in a limited period of time constitutes an important feature of many law-enforcement policies around the world. In this paper, we offer a comprehensive investigation on the relative efficiency and effectiveness of various crackdown policies using a lab-in-the-field experiment with real passengers of a public transport service. We introduce a novel game, the daily public transportation game, where subjects have to decide, over many periods, whether to buy or not a ticket knowing that there might (...) be a control. Our results show that concentrated crackdowns are less effective and efficient than random controls; prolonged crackdowns reduce fare-dodging during the period of intense monitoring but induce a burst of fraud as soon as they are withdrawn; pre-announced controls induce more fraud in the periods without control. Overall, we also observe that real fare-dodgers fraud more in the experiment than non-fare-dodgers. (shrink)

Apresentação do dossiê comemorativo do centenário de publicação do livro _Duração e simultaneidade_, de Henri Bergson.

A famosa filosofia materialista e ateísta de Holbach é menos conhecida por sua dimensão política. Ainda assim, o autor propôs uma teoria original do contrato social em suas obras da década de 1770. Este artigo detalha as principais características de seu pensamento político e de sua ideia de contrato social, destacando sua proposta de uma “Etocracia”, que se fundamenta na utilidade e na justiça. Essa Etocracia abre caminho para um republicanismo pluralista com traços originais na história das ideias. Holbach era (...) leitor de Hobbes e Locke, conhecido de Rousseau e propôs várias críticas aos escritos políticos desses autores. Por meio de cinco críticas principais, este artigo mostra ainda o valor da teoria positiva de Holbach em conceitos-chave como estado de natureza, sociabilidade, propriedade, vontade geral e igualdade. Por último, a potencial contribuição de Holbach para a teoria política é destacada, mostrando como esse autor, em grande medida esquecido, merece a nossa atenção nos dias de hoje. (shrink)

This article explores the construction of offences as ‘accidental’ in police-suspect interactions. The data comprise audio-recorded investigative interviews, which were analysed using conversation analysis. In these interviews, suspects often do not explicitly state the nature of their defence when answering police officers’ questions; instead, suspects’ defensive practices or techniques are embedded in the narrative accounts they give of what happened, thus exhibiting rather claiming their ‘innocence’. My focus here is on a particular type of defence, namely, one in which suspects (...) portray an event as having been ‘accidental’. I show that this defence of ‘accident’ is associated with several discourse features including: building a plausible and trivial context in which the untoward incident occurred, describing the untoward action or series of actions, using impersonal or agentless constructions, and representing the disproportionality between the putative victim’s reaction and the aggressor’s untoward conduct. The accountability of these descriptions, however, does not rely on one unique feature, but rather on suspects’ ability to combine these features in such a way that each establishes the grounds for others.
