Based on the notion of bad faith, the article seeks to lay the foundations for a diagnosis of contemporaneity, having as an index, on the one hand, the lack of human determination and, on the other, the effectiveness of the world.

Internal misconduct is a universal problem in prisons and affects the maintenance of social order. Consequently, correctional institutions often develop rehabilitation programs to reduce the likelihood of inmates committing internal offenses and criminal recidivism after release. Therefore, it is necessary to identify the profile of each offender, both for the appropriate indication of a rehabilitation program and the level of internal security to which he must be submitted. In this context, this work aims to discover the most significant characteristics in (...) predicting inmate misconduct from ML methods and the SHAP approach. A database produced in 2004 through the Survey of Inmates in State and Federal Correctional Facilities in the United States of America was used, which provides nationally representative data on prisoners from state and federal facilities. The predictive model based on Random Forest performed the best, thus, we applied the SHAP to it. Overall, the results showed that features related to victimization, type of crime committed, age and age at first arrest, history of association with criminal groups, education, and drug and alcohol use are most relevant in predicting internal misconduct. Thus, it is expected to contribute to the prior classification of an inmate on time, to use programs and practices that aim to improve the lives of offenders, their reintegration into society, and consequently, the reduction of criminal recidivism.

O artigo analisa os pressupostos para a questão da existência de uma ética em Jean-Paul Sartre. Para tanto, discute a relação da forma ensaística com o pensamento de Sartre, especialmente em L’être et le néante se debate a pertinência da noção de autenticidade, questionando-a a partir da crítica da noção de origem. A partir desses dois temas, a pergunta sobre uma ética sartriana é posta sob duas dimensões irredutíveis: impossibilidade de se efetivar enquanto tal e, ao mesmo tempo, exigência da (...) questão ética em qualquer reflexão sobre a filosofia de Sartre. Por fim, o problema moral, com seus paradoxos e suas exigências, ainda se mostra como a privilegiada alternativa de uma contemporaneidade para o existencialismo. (shrink)

Proper fork algebras are algebras of binary relations over a structured set. The underlying set has changed from a set of pairs to a set closed under an injective function. In this paper we present a representation theorem for their abstract counterpart, that entails that proper fork algebras — whose underlying set is closed under an injective function — constitute a finitely based variety.1.

Pre-eminent among European political philosophers, Norberto Bobbio has throughout his career turned to the political theory of Thomas Hobbes. Gathered here for the first time are the most important of his essays which together provide both a valuable introduction to Hobbes's thought and a fresh understanding of Hobbes's place in the theory of modern politics. Tracing Hobbes's work through De Cive and Leviathan , Bobbio identifies the philosopher's relation to the tradition of natural law. That Hobbes must now be (...) understood in both this tradition as well as in the seemingly contradictory positivist tradition becomes clear for the first time in Bobbio's account. Bobbio also demonstrates that Hobbes cannot be easily labelled "liberal" or "totalitarian" in Bobbio's provocative analysis of Hobbes's justification of the state, Hobbes emerges as a true conservative. Though his primary concern is to reconstruct the inner logic of Hobbes's thought, Bobbio is also attentive to the philosopher's biography and weaves into his analysis details of Hobbes's life and world--his exile in France, his relation with the Mersenne circle, his disputes with Anglican bishops, and accusations of heresy leveled against him. The result is a revealing, thoroughly new portrait of the first theorist of the modern state. (shrink)

Despite being fairly powerful, finite non-deterministic matrices are unable to characterize some logics of formal inconsistency, such as those found between mbCcl and Cila. In order to overcome this limitation, we propose here restricted non-deterministic matrices (in short, RNmatrices), which are non-deterministic algebras together with a subset of the set of valuations. This allows us to characterize not only mbCcl and Cila (which is equivalent, up to language, to da Costa's logic C_1) but the whole hierarchy of da Costa's calculi (...) C_n. This produces a novel decision procedure for these logics. Moreover, we show that the RNmatrix semantics proposed here induces naturally a labelled tableau system for each C_n, which constitutes another decision procedure for these logics. This new semantics allows us to conceive da Costa's hierarchy of C-systems as a family of (non deterministically) (n+2)-valued logics, where n is the number of "inconsistently true" truth-values and 2 is the number of "classical" or "consistent" truth-values, for every C_n.

From the early to mid-1970s, Michel Foucault posited that power consists of a relation rather than a substance and that this relation is comprised of unequal forces engaged in a warlike struggle against each other, resulting invariably in the domination of some forces over others. This understanding of power, which he retrospectively dubbed `Nietzsche's hypothesis' and `the model of war', underpinned his well-known analyses of disciplinary power. Yet, Foucault in his Collège de France course from the academic year 1975-6, `Society (...) Must Be Defended', suddenly began to call into question this understanding and his doubts about it did not abate well into the late 1970s. In this article, we suggest that his militant politics in the early 1970s sustained his adherence to the war model and that his more cautious political attitude later in the decade underpinned his suspicions about this model. Key Words: biopolitics • Henri de Boulainvilliers • Michel Foucault • Thomas Hobbes • militancy • F. W. Nietzsche • politics • power • race • war. (shrink)

Au cours de cet entretien, Emmanuel Renault nous offre un aperçu de la manière dont la thématique de la reconnaissance est traitée en France aujourd’hui, notamment à travers le renouveau des études sur Hegel et Marx. Il explique la façon dont la reconnaissance a pu s’ériger en paradigme (en dépit de ses usages multiples et variés en France comme ailleurs), au cours de la dernière décennie et le rôle joué par Axel Honneth dans ce procès. Finalement, il explicite sa manière (...) d’envisager la pratique de la philosophie politique et son projet d’une critique du capitalisme. Emmanuel Renault nous livre également un commentaire critique mais constructif sur la manière dont Paul Ricœur envisage la reconnaissance et suggère quelques pistes concernant les possibles développements futurs des usages de la reconnaissance.

Suszko's Thesis maintains that many-valued logics do not exist at all. In order to support it, R. Suszko offered a method for providing any structural abstract logic with a complete set of bivaluations. G. Malinowski challenged Suszko's Thesis by constructing a new class of logics (called q-logics by him) for which Suszko's method fails. He argued that the key for logical two-valuedness was the "bivalent" partition of the Lindenbaum bundle associated with all structural abstract logics, while his q-logics were generated (...) by "trivalent" matrices. This paper will show that contrary to these intuitions, logical two-valuedness has more to do with the geometrical properties of the deduction relation of a logical structure than with the algebraic properties embedded on it.

This article discusses the contribution to evolutionary theory of Leonard Darwin, the eighth child of Charles Darwin. By analysing the correspondence Leonard Darwin maintained with Ronald Aylmer Fisher in conjunction with an assessment of his books and other written works between the 1910s and 1930s, this article argues for a more prominent role played by him than the previously recognised in the literature as an informal mentor of Fisher. The paper discusses Leonard’s efforts to amalgamate Mendelism with both Eugenics and (...) Darwinism in order for the first to base their policies on new scientific developments and to help the second in finding a target for natural selection. Without a formal qualification in biological sciences and as such mistrusted by some “formal” scientists, Leonard Darwin engaged with key themes of Darwinism such as mimicry, the role of mutations on speciation and the process of genetic variability, arriving at important conclusions concerning the usefulness of Mendelian genetics for his father’s theory.

We provide a model in which students must choose whether or not to cheat on a course exam. By assuming that the moral cost of acting dishonestly decreases as the number of other people who behave in the same way increases, our model explains one important channel by which unethical behavior of other individuals can influence observers’ behavior. Through the use of the Global Games approach of equilibrium selection, we build a framework that provides the micro-foundations of peer effects on (...) academic dishonesty and shows how better student technology of cheating and higher disutility of effort make the cheating equilibrium more likely to be selected. By extending the model, we find that the peer effect strength is not affected by the level of homogeneity of the cohort, but decreases in the size of the class. Our approach may be seen as an important step towards reduced-form models of peer effects on dishonest behavior. (shrink)

This article sets out to revisit Herbert Marcuse’s “transcendent project” of liberation, as well as his notion of “post-technological rationality,” which grounded this project, articulated in outline form in the last section of One-Dimensional Man and in fragments throughout his middle writings between 1955 and 1972. The aim is to assess this project’s continued validity for the struggle for alternatives to the disorganizations and enclosures of neoliberal capitalism and its perpetual moments of crises. This article first reviews Marcuse’s place within (...) substantivist critiques of technology. It then works through how Marcuse’s “post-technological rationality”—the other side of his technology critique—envisions social change happening via a rerationalized, revalued, and reaestheticized technological base spurred by the openings for alternatives made possible by a reconstituted subjectivity, determinate negation, and moments of crisis.

blandior ratio : C, 34). I will first survey how extensive, albeit usually overlooked, is Leibniz’s concern with these “weaker” forms of reasoning, and how crucial they are for many of his practical and theoretical endeavors. I will then trace back this acute need of Leibniz´s brand of rationalism to the peculiar nature of the Principle of Sufficient Reason (PSR), as opposed to the other basic principle of his philosophy, the Principle of Contradiction (PC). I will present here only the (...) bare bones of the argument, in a sort of extended summary, omitting the textual support as well the references to the relevant secondary literature. (shrink)

In 1940 Dugundji proved that no system between S1 and S5 can be characterized by finite matrices. Dugundji’s result forced the development of alternative semantics, in particular Kripke’s relational semantics. The success of this semantics allowed the creation of a huge family of modal systems. With few adaptations, this semantics can characterize almost the totality of the modal systems developed in the last five decades. This semantics however has some limits. Two results of incompleteness showed that not every modal logic (...) can be characterized by Kripke frames. Besides, the creation of non-classical modal logics puts the problem of characterization of finite matrices very far away from the original scope of Dugundji’s result. In this sense, we will show how to update Dugundji’s result in order to make precise the scope and the limits of many-valued matrices as semantic of modal systems. A brief comparison with the useful Chagrov and Zakharyaschev’s criterion of tabularity for modal logics is provided. (shrink)

We present a distributed control modeling approach for an automated manufacturing system based on the dynamics of one-dimensional cellular automata. This is inspired by the fact that both cellular automata and manufacturing systems are discrete dynamical systems where local interactions given among their elements can lead to complex dynamics, despite the simple rules governing such interactions. The cellular automaton model developed in this study focuses on two states of the resources of a manufacturing system, namely, busy or idle. However, the (...) interaction among the resources such as whether they are shared at different stages of the manufacturing process determines the global dynamics of the system. A procedure is shown to obtain the local evolution rule of the automaton based on the relationships among the resources and the material flow through the manufacturing process. The resulting distributed control of the manufacturing system appears to be heterarchical, and the evolution of the cellular automaton exhibits a Class II behavior for some given disordered initial conditions.

Purpose– The purpose of this paper is to examine how Slow Tech can support the celebration of the 20-year series of ETHICOMP conferences, with its ethical and societal focus, building on earlier descriptions of Slow Tech. The paper takes Slow Tech’s ideas a step further to explore how a roadmap and concrete checklist of activities can be developed.Design/methodology/approach– The paper is a thought leadership or conceptual piece. Its approach is based on a normative, qualitative discourse. It, nevertheless, indicates a shift (...) towards concrete actions.Findings– Extracting from a brief historical overview, the paper lays out the means of building a Slow Tech roadmap and a Slow Tech checklist of actions. It also investigates a number of the challenges that might face Slow Tech in the future.Research limitations/implications– The paper has implications for stakeholder fields as far-ranging as corporations, computing professional associations, universities and research institutions and end-users.Originality/value– As with other investigations of Slow Tech, the value of this paper is in its call for reflection followed by action. It provides a useful complement and counterbalance to an earlier paper by the same authors: “Slow Tech: a quest for good, clean and fair ICT” published inJournal of Information, Communication and Ethics in Society(Vol. 12, issue 2, pp. 78-92).

The text is part of the investigative concerns from the authors with regard to the dialogue between literature and science teaching. It starts from several theoretical approaches around the general didactics, university or superior didactics, science’s didactics and for last, literature’s didactics. This is largely due to our search which is focused in articulate the university didactics with science and literature’s didactics, meanwhile, we pretend to answer to the questions ¿How are the specific didactics of science and literature going to (...) contribute to the university didactics and how is the last one going to contribute to these specific didactics? ¿Is it the dialogue between science and literature possible? The paper has been made in middle education, in Educative Institution José Miguel de Restrepo y Puerta, from Copacabana and also in university education, in the academic unities of Dietetics and Nutrition School, Agricultural Sciences and Medicine, from the University of Antioquia. Finally, the partial results indicate: i) the necessity of general Didactics as a discipline focused on teaching and learning processes to ask itself for its internal problems and establish relations with specific didactics.

Dichotomies are ubiquitous in deliberative thinking, in decision making and in arguing in all spheres of life.[i] Sticking uncompromisingly to a dichotomy may lead to sharp disagreement and paradox, but it can also sharpen the issues at stake and help to find a solution. Dichotomies are particularly in evidence in debates, i.e., in argumentative dialogical exchanges characterized by their agonistic nature. The protagonists in a debate worth its name hold positions that are or that they take to be opposed; they (...) argue against each other’s positions; and they defend their positions from the adversary’s attacks. In some cases, this may lead to a polarization of the debate through treating it as grounded on one or more dichotomies. In others, the contenders may construe the opposition as non-dichotomous and therefore less irreconcilable. Whereas the former attitude, which leads to ‘dichotomization’, is likely to radicalize a debate, rendering it difficult – sometimes impossible – to resolve, the latter, which leads to ‘de-dichotomization’, opens possibilities of solution of the debate other than all out victory of one side and defeat of the other. In addition to its effect on the outcome of a debate, the contenders’ attitude towards dichotomies in the debate’s management has further, important implications. It is intrinsically connected with the typology of debates and their typical argumentative moves. For the appropriateness of one or the other of these attitudes for best capturing the nature of the antagonism that underlies a debate is in fact an indicator of the kind of debate it actually is or is perceived by the contenders to be. Furthermore, such ‘attitudes’ are expressed by the contenders’ preferred choices of argumentative moves; and these, in turn, can be recognized, in a given debate context, as subservient either to a dichotomizing or to a de-dichotomizing strategy vis-à-vis a dichotomy taken to be at the root of the divergence.

L'œuvre de Michel Foucault est inclassable car elle traverse des domaines très variés (philosophie, sociologie, histoire, anthropologie, criminologie, médecine, psychologie, linguistique, droit, etc.). Foucault n'est pas un sociologue au sens classique du terme. Il existe une sociologie puissante et novatrice chez lui. Mais laquelle? À quoi peut-elle servir aujourd'hui? En quoi est-elle utile pour théoriser les problèmes sociaux? Quels sont ses avantages et ses inconvénients? Quel type de « raisonnement sociologique » se dégage de son œuvre et quelles sont ses (...) limites? Voilà les interrogations qui guident l'analyse de l'ensemble des travaux de Foucault dans cet ouvrage.

The paper aims to investigate the ethical motive which led Husserl to defend the transcendental subjectivity. The central thesis is that phenomenological attitude is more than a pure methodical and theoretical approach on human subjectivity. Husserlian’s use of the transcendental ego has a practical purpose. Considering that phenomenology always begins by the suspension of the natural attitude, the possibility of this suspension implicates a paradox: the ego must preserve his belief in reason and science in order to carry out the (...) neutralization of its beliefs concerning natural attitude. This belief is crucial in order to understand the ethical meaning of the transcendental reduction which is the beginning of an entirely new form of life. (shrink)

Purpose– The purpose of this paper is to introduce the term Slow Tech as a way of describing information and communication technology that is good, clean and fair. These are technologies that are human centred, environmentally sustainable and socially desirable.Design/methodology/approach– The paper's approach is based on a qualitative discourse that justifies the introduction of Slow Tech as a new design paradigm.Findings– The limits of the human body, and the need to take into account human wellbeing, the limits of the planet (...) and stakeholders' interests in decision making, all suggest the need for a new paradigm, Slow Tech, in the design of ICT and ICT systems. Three scenarios are described as case studies.Practical implications– In order to prepare the next generation of researchers and computer professionals, many different actions need to be taken. Universities and colleges need to redesign education programmes for computer scientists and engineers by introducing subjects related to the social and ethical implications of computing, and computer professionals' associations need to introduce a code of ethics or ethical analysis into their members' career development. As a result, future computer professionals who are familiar with the Slow Tech approach will be able to collaborate much more easily across the kind of cross disciplinary teams suited to design human centred, sustainable and desirable technologies.Social implications– Rather than simply focusing on the role of computer professionals, all members of society are called to play a new role in the design of future ICT scenarios. Starting a societal dialogue that involves computer professionals, users, researchers, designers, ICT industrialists, and policy makers is very much needed.Originality/value– The value of this paper is in its call for reflection followed by action. Based on an holistic approach to the design of new ICT systems, the paper advocates a new starting point for systems design: it should be based on a long-term view of the desirability and social importance of technologies, their environmental impact and sustainability, and the fairness and equity of the conditions of workers involved in the computing manufacturing processes.

Communication is a crucial component of scientific activity (as of virtually any other domain of human activity, especially in this "communication age" in which we live). As researchers and as citizens, we should all be concerned with the communication of science as well as with communication within science. In this paper, I will deal with one of the key aspects of this topic ג€“ the question whether scientific communication is or should be ג€�transparentג€�. The view that this is or should (...) be the case is often taken for granted both by scientists and the general public. I will challenge this view and suggest that we should learn to live without the illusion that scientific communication is or should be transparent. This idea is closely related, if not derived from, the traditional epistemological conception according to which scientific method is the privileged tool we have for penetrating beyond appearances and discovering the true ג€�nature of thingsג€�, in terms of which all observable phenomena should be ultimately explained. Applying the scientific method should, thus, yield a fully intelligible representation of the world, which in its turn should be transparently communicable. The trouble with this enticing ideal is that it does not correspond to actual practice. Again and again we experience the fact that the ג€�true picture of the worldג€� remains veiled for everyone but a small group of initiated experts in a narrow domain. Is this only a technical problem having to do with the phenomenon of specialization and with the inevitable complexity of the language(s) of science, as it is often suggested? (shrink)

RESUMEN En este artículo abordamos la cuestión del poder en el pensamiento de Deleuze. Según nuestra hipótesis, no hay en su obra un único concepto de poder sino diferentes enfoques no incompatibles entre sí pero que no se dejan reducir a un solo punto de vista. Esta variedad de abordajes puede ser reunida alrededor de dos posiciones generales adoptadas por Deleuze: primero, tiende a relativizar su eficacia respecto de otros elementos más fundamentales, realzando así los límites o la impotencia del (...) poder; segundo, le quita valor con relación a otras entidades y procesos en los que deposita su apuesta filosófica. Nos proponemos desarrollar estas perspectivas a fin de ofrecer un panorama integral de una temática relevante de la filosofía política deleuziana. ABSTRACT In this article, we address the question of power in Deleuze's thinking. According to our hypothesis, there is not a single concept of power in his work, but different approaches not incompatible with each other but that cannot be reduced to a single point of view. This variety of approaches can be gathered around two general positions about power, adopted by Deleuze: first, he tends to relativize its effectiveness with respect to other more fundamental elements, thus enhancing the limits or impotence of power; second, he takes away value in relation to other entities and processes in which he places his philosophical commitment. We intend to develop these perspectives in order to offer a comprehensive overview of a relevant theme of Deleuzian political philosophy. (shrink)

There is a death by suicide in the world every 40 seconds, and suicide is the second leading cause of death for 15–29-year-olds. Experts say that one of the best ways to prevent suicide is for those in distress to hear from people who care about them. Facebook is in a unique position—through its support for networks and friendships on the site—to help connect a person in these difficult situations with people who can support them. Connecting people with the resources (...) they need is part of Facebook’s ongoing efforts to help build a safe community inside and outside of Facebook. This article provides a brief overview of how Facebook’s work to develop suicide prevention tools started and evolved, and the ethical considerations which surfaced during the process in the form of concrete product decisions around the implementation of these tools. This article is structured into three sections. Section 1 reviews what has been done in this space and lists and briefly describes other suicide prevention apps and tools. Section 2 describes Facebook’s overall approach to suicide prevention. Here, we’ll delve first into how that approach originated and how it was influenced by the external community’s proactive interactions with Facebook, highlighting our unique position to help address the problem. Afterwards, we’ll explain how that approach evolved, describing its various stages and iterations: understanding, reactive reporting, queue prioritization, and proactive reporting. This section describes the tools and resources Facebook has developed for people who may be at risk. Particular attention is devoted to the use of ArtificiaI Intelligence and Machine Learning to detect posts or live videos where someone might be expressing thoughts of suicide. Section 3 will elaborate on the ethical questions addressed when developing our approach and when making concrete product decisions to implement our suicide prevention tools. In this last section, we’ll expound the competing values and interests that were at stake during the product development process, and how we reached ethical balances between them. (shrink)

A Political Life is the compelling autobiography of Norberto Bobbio, one of the foremost political thinkers in postwar Italy. In dramatic and lively prose, Bobbio guides us through some of the most significant events of the twentieth century, charting their influence on his life and work. Born in 1909, Norberto Bobbio's early life was marked by the experience of growing up in Mussolini's Italy - an experience that helped to shape his passionate commitment to the anti-fascist cause. As (...) a result of these early experiences, Bobbio has tirelessly emphasized the fundamental, unassailable importance of democratic rights in the modern state. He has been a voice of reason and moderation in a political context where democratic values have often been threatened by extremes. This masterly autobiography traces the development of Bobbio's political thought, providing a penetrating analysis of the changing political landscape of Italy. At the same time, it represents an intimate account of Bobbio's personal experiences, giving a rare insight into the life and work of this distinguished thinker.A Political Life will be of great interest to students and scholars of social and political theory and of Italian politics, as well as to a general readership interested in political biography and contemporary politics.

Multialgebras (or hyperalgebras) have been very much studied in the literature. In the realm of Logic, they were considered by Avron and his collaborators under the name of non-deterministic matrices (or Nmatrices) as a useful semantics tool for characterizing some logics (in particular, several logics of formal inconsistency or LFIs) which cannot be characterized by a single finite matrix. In particular, these LFIs are not algebraizable by any method, including Blok and Pigozzi general theory. Carnielli and Coniglio introduced a semantics (...) of swap structures for LFIs, which are Nmatrices defined over triples in a Boolean algebra, generalizing Avron's semantics. In this paper we develop the first steps towards the possibility of defining an algebraic theory of swap structures for LFIs, by adapting concepts of universal algebra to multialgebras in a suitable way.

In the first part of this paper we analyzed finite non-deterministic matrix semantics for propositional non-normal modal logics as an alternative to the standard Kripke possible world semantics. This kind of modal system characterized by finite non-deterministic matrices was originally proposed by Ju. Ivlev in the 70s. The aim of this second paper is to introduce a formal non-deterministic semantical framework for the quantified versions of some Ivlev-like non-normal modal logics. It will be shown that several well-known controversial issues of (...) quantified modal logics, relative to the identity predicate, Barcan’s formulas and de re and de dicto modalities, can be tackled from a new angle within the present framework.
