We propose an extension of answer sets, that we call safe beliefs, that can be used to study several properties and notions of answer sets and logic programming from a more general point of view. Our definition, based on intuitionistic logic and following ideas from D. Pearce [Stable inference as intuitionistic validity, Logic Programming 38 79–91], also provides a general approach to define several semantics based on different logics or inference systems. We prove that, in particular, intuitionistic logic can be (...) replaced with any other proper intermediate logic without modifying the resulting semantics. We also show that the answer set semantics satisfies an important property, the “extension by definition”, that can be used to construct program translations. As a result we are able to provide a polynomial translation from propositional theories into the class of disjunctive programs. (shrink)

Despite frequent calls for the overhaul of null hypothesis significance testing (NHST), this controversial procedure remains ubiquitous in behavioral, social and biomedical teaching and research. Little change seems possible once the procedure becomes well ingrained in the minds and current practice of researchers; thus, the optimal opportunity for such change is at the time the procedure is taught, be this at undergraduate or at postgraduate levels. This paper presents a tutorial for the teaching of data testing procedures, often referred to (...) as hypothesis testing theories. The first procedure introduced is Fisher's approach to data testing—tests of significance; the second is Neyman-Pearson's approach—tests of acceptance; the final procedure is the incongruent combination of the previous two theories into the current approach—NSHT. For those researchers sticking with the latter, two compromise solutions on how to improve NHST conclude the tutorial. (shrink)

Este artigo, inserido no âmbito da História das Ideias, busca elaborar um panorama das posições que se contrastam no interior do conjunto de discursos anti-escravistas do século XIX, enfatizando as nuances presentes nas posturas “emancipacionista” e “abolicionista”, e no interior desta última as nuances que podem ser identificadas e que distinguem um abolicionismo moderado de um abolicionismo radical. O ponto de partida da análise é a distinção entre dois modos de conceber a Escravidão: como Desigualdade ou como Diferença. A análise (...) desenvolve-se a partir da leitura de textos da época, incluindo autores como José Bonifácio de Andrade e Silva, André Rebouças, Joaquim Nabuco e José do Patrocínio, entre outros.

A Trifuncionalidade como Ideologia O estudo das ideologias, no âmbito da História das Idéias, tem gerado algumas das temáticas mais importantes e polêmicas da historiografia das últi­mas décadas, sendo estas particularmente significativas para a compreensão das relações entre representações sociais e Política nos vários períodos históri­cos. Neste ensaio, que examinará a clássica discussão historiográfica sobre a 'trifuncionalidade medieval', estaremos considerando "ideologia" como uma n...

O principal propósito deste artigo é discutir uma das mais importantes questões relativas à interação entre Cristianismo e Política nos vários períodos da Idade Média: a relação entre Império e Igreja. O tema será abordado com base no exame de alguns dos aspectos políticos e imaginários envolvidos nesta relação que, à partida, contrasta dois projetos de cunho universalista que terminam por se opor no contexto político e religioso do período medieval. Entre as questões examinadas, um ponto importante será constituído por (...) uma reflexão sobre as origens da noção de Império a partir do Império Romano e, posteriormente, do Império Carolíngio, assim como suas projeções subseqüentes, inclusive no período que ultrapassa a Idade Média em direção à Modernidade. O relacionamento entre Império e Papado, conforme veremos, foi constituído no período examinado por uma alternância de momentos de aliança e oposição política, mas durante todo o período também pode ser pensado nos termos de um grande confronto, entre os poderes secular e religioso, que envolve as noções de “igreja”, “império” e “reino”. Palavras-chaves : Império, Igreja, Realeza, Papado, PoderThe mainly purpose of this article is to discuss one of the most important questions refereed to the interaction between Christianism and Politics in the various periods of the Middle Ages: the relation between Empire and Ecclesia. The theme will be analyzed on basis of the examination of some political and imaginary aspects involved of this relation that, in first place, contrasts two universal projects that falls in opposition in the political and religious context of the Middle Ages. Among the questions examined, an important point will be constituted by the origins of the notion of Empire since the Roman Empire and, later, the Carolingian Empire, as also their subsequent projections, including in the period that exceeds the Middle Ages in direction to Modernity. The relationship between Empire and Papacy, as we shall see, was constituted by the alternation of moments of alliance and political opposition, but throughout the entire period it can be also thought in terms of a great confrontation between secular and religious powers that involves the notions of “ecclesia”, “empire” and “kingdom”. Key words : Empire, Church, Royalty , Papacy, Power. (shrink)

Nos livros impressos, nem sempre as imagens estão de acordo com os textos que deveriam ilus­trar. Neste artigo, o autor analisa algumas estampas xilográficas que estão em desacordo com os textos que 'ilustram', em O Flos Sanctorum em linguagem português, impresso em Lisboa, por Hermão de Campos & Roberto Rabelo, em 1513.

Offering a contemporary perspective on the theory of modernity that differentiates it from its predecessors, this reconstruction has been expanded to include a fourth instrumental aspect. In addition to the recognition of the three parts of traditional modernity—freedom, equality, and solidarity—that follow the basic ideas of the constitutional revolutions of the 18th century, this updated vision introduces responsibility. Concerning itself with what the sociology of development, risk, and ecological crisis have added to these classical ideas, the addition of the fourth (...) part, responsibility, seeks to recognize the experiences of successive eras, and the 20th century in particular.

O texto apresenta a apropriação feita pela extrema-direita brasileira ao redor da obra de George Orweel, em especial, de '1984' e 'Animal Farm'. Argumentamos que a adjudicação 'conservadora' é inadequada para tal apropriação. Os intelectuais e editoriais implicados na circulação atual de Orwell nas redes bolsonaristas permite ver como clássicos do pensamento conservador ocidental são aqui canonizados em chave, mais que conservadora, reacionária. Além disso, o duelo de distopias empunhados pelos ideólogos da extrema-direita dá também acesso a uma indústria cultural, (...) na qual um sem-fim de produtos culturais são vendidos para forjar e cativar uma plateia potencial reacionária.

This paper analyses the gender pay determinants between top and lower level of Portuguese employees. A relatively large data pool, for 2003, covering business functions hitherto neglected, sheds a new light into the factors that lead to the earnings of men and women. Our analysis combines human capital with internal-labour-markets theories. Our findings allow the identification of jobsegregation as one important source of the gender pay gap. Moreover, they confirm that earnings are determined by different factors and suggest a reasonable (...) opportunity for women to combine career and family. (shrink)

A revista Logos apresenta o dossiê “Realidade e Ficção” como contribuição ao desenvolvimento de pesquisas empíricas e reflexões sobre fronteiras e hibridismos entre realidade e ficção nas narrativas midiáticas. Ainda que, em alguns trabalhos, o tema não desponte na linha de frente, suas implicações podem ser desveladas nas marcas das textualidades que compõem lógicas próprias e peculiares de suas abordagens. O conjunto de artigos, entretanto, permite visualizar soluções comuns encontradas pelos autores para o enfrentamento da questão, presente nos processos, métodos (...) e linguagens que conduzem ao entendimento de conceitos-chave como representação, imaginário e identidade. Do ponto de vista dos objetos empíricos analisados, o dossiê, além de contemplar o campo jornalístico, abre também espaço para o cinema e a televisão, ora situando o debate na intercessão entre tais veículos, ora explorando as especificidades de cada um.

ABSTRACT This article1 reports an ongoing experience involving the application of research to teaching that articulates various disciplines and curricular contexts within a Post-graduate Program in Literature and Literary Criticism. Through the use of active teaching-learning methodologies and digital information and communication technologies, we seek to put some core dilemmas of literary studies into dialogue with notions and practices of open science. Throughout this process, we laid the groundwork for a digital platform that would bring together the results of research (...) developed in the context of these various disciplines and make them readily available to their respective audiences and sociocultural territories. By raising awareness concerning the social impact of the program’s research, this report should prompt reflection on how to foster articulation between heterogeneous academic and social contexts, both within the classroom connected to other environments and in open scientific productions, accessible to different audiences.

Joining the university context in the middle of the 19th century, Philology served as a comprehensive basis for what nowadays is meant by literary and linguistic studies. Depending on the specialization tendency that would settle down in the academic context, each of these areas followed separate or even divergent paths, losing, to a great extent, the contact with its initial basis. Despite this state of affairs, Philology has displayed a strong capacity of resistance, maintaining its traditional dimension active or going (...) through metamorphoses that resulted from the incorporation of new technologies, as well as from the epistemological adjustment that enabled it to overcome its first positivist stages. Trying to find a new place inside the general framework of Social Sciences and Humanities, literary studies need to recover its order and credibility, two factors that the new face of Philology can inspire. The present study aims at reconstructing the most recent trajectory undergone by this field of research and education, by identifying a space of reconnection that already seems to be adequate and beneficial.

This article analyses recent social, cultural and political developments in Latin America, with special reference to the `modernity/coloniality' project, as well as offering an alternative sociological interpretation of the contemporary subcontinent. It analyses in particular Walter Mignolo's work as the main expression of that `post/decolonial' project, a general interpretive effort that reflects actual social changes but offers misguided theoretical and political perspectives. The article then proposes a discussion of modernity as a global civilization which is now unfolding its third phase, (...) characterized by greater complexity and pluralism. In addition it argues that modernity should be seen as a two-pronged phenomenon, featuring not only domination but also emancipation. Against the reification of modernity, the article suggests that we see it as woven by multiple and contingent modernizing moves. (shrink)

Two of the most well-known belief contraction operators are partial meet contractions (PMCs) and kernel contractions (KCs). In this paper we propose two new classes of contraction operators, namely the class of generalized partial meet contractions (GPMC) and the class of generalized kernel contractions (GKC), which strictly contain the classes of PMCs and of KCs, respectively. We identify some extra conditions that can be added to the definitions of GPMCs and of GKCs, which give rise to some interesting subclasses of (...) those classes of functions, namely the classes of extensional and of uniform GPMCs/GKCs. In the context of contractions on belief sets the classes of partial meet contractions, uniform GPMCs and extensional GPMCs are all identical. Nevertheless, when considered as operations on belief bases, the class of uniform GPMCs coincides with the class of partial meet contractions, but the extensional GPMCs constitute a new kind of belief base contraction functions whose characterizing postulate of irrelevance of syntax is extensionality—the same postulate of irrelevance of syntax which occurs in the classical axiomatic characterization of partial meet contractions for belief sets—rather than the postulate of uniformity—which is the irrelevance of syntax postulate used in the axiomatic characterization for partial meet contractions on belief bases. Analogous results are obtained regarding the classes of extensional and of uniform GKCs. We present the interrelations in the sense of inclusion among all the new classes of operators presented in this paper and several well known classes of PMCs and of KCs. (shrink)

The historical formation of Brazil is distinguished from the majority of ex-colonial nations by one factor that is especially characteristic: an intense process of ethnic and cultural mixing. The Portuguese colonisers, who, unlike the English Puritans in North America, left their families and arrived in Brazil in small groups mainly composed of men, naturally tended to pair off with the women they found available - first of all indigenous women and later African women. There was nothing in Brazil to prevent (...) this spontaneous behaviour similar to the role played in the English colonies of North America by the strength of the family group or the strict religious observance of the community. Thus from the outset Brazil tended to accept racial mixing as a de facto reality. As Gilberto Freyre correctly noted in his book Casa Grande e Senzala:They mixed happily with women of colour from the very first contacts and many mixed-race children resulted, so much so that only a few thousand men were enough to colonize vast areas and compete with the greatest and most numerous peoples as regards the extent of the colonial territory and the effectiveness of colonizing activity.

A reflection on how to teach philosophy with the help of theatrical techniques and scenic interpretation tools, building an allegorical environment for the presentation of philosophical content. Considering Plato's explanation of the allegory of the cave, where he starts from 'appears' or 'imagines' and describes his narrative, in a complete way, in a theatrical approach to use the imagination of his listeners. And thus building a scene, a representation of what he wanted to teach his interlocutors. In addition to reflecting (...) on contemporary caves, built in the rooms of young people, who are isolated, attentive only to the images produced on cell phone and computer screens, without being sure about the veracity of the information received in these 'walls' of modern caves. Also following the approaches and paths of Deleuze and Foucault in their considerations on the constructions relevant to the study of philosophy and its learning, this article aims at this reflection as a contribution to the art of theatre, the 'teatron', the place for to see. And to see how this seeing is a metaphorical perspective, something that is also a philosophical question, both in the direct and in the metaphysical sense. In addition to being a matter of experience made possible by immersion in the world of ideas and imagination, in a reflective, pragmatic way and with a view to learning and teaching philosophy.

Culture has been at the core of many recent developments in the social sciences, particularly after the so-called ‘linguistic turn’. This has also been seeping into discussions about the relation between culture and politics. The present paper proposes a specific theoretical approach in this respect. It mobilizes Castoriadis’s concept of the ‘imaginary’, as well as those of ‘collective subjectivity’ and ‘social creativity’. It also makes use of the rich case of ‘populism’, more generally, and Peronism, more specifically, so as to (...) make clear its workings in a sociological strategy that unfolds in both the theoretical and the empirically-oriented domains. The paper offers an alternative to Alexander’s and Laclau’s approaches to culture and politics. (shrink)

In the logic of theory change, the standard model is AGM, proposed by Alchourrón et al. (J Symb Log 50:510–530, 1985 ). This paper focuses on the extension of AGM that accounts for contractions of a theory by a set of sentences instead of only by a single sentence. Hansson (Theoria 55:114–132, 1989 ), Fuhrmann and Hansson (J Logic Lang Inf 3:39–74, 1994 ) generalized Partial Meet Contraction to the case of contractions by (possibly non-singleton) sets of sentences. In this (...) paper we present the possible worlds semantics for partial meet multiple contractions. (shrink)

Roger Garaudy é um filósofo francês que muda de uma posição inicialmente marxista para outra existencialista. A sua aproximação com o existencialismo se dá na década de 70 quando o pensador foi expulso do Partido Comunista Francês por discordar dos rumos do marxismo de então. Ao mesmo tempo ele descobre no existencialismo a chave teórica que justifica sua preocupação humanista. Da fase marxista, o filósofo preserva os elementos éticos e as preo­cupações sociais que ele transfere para sua filosofia existencial. Garaudy (...) espera com eles resol­ver os problemas de uma subjetividade que cresceu além da conta nos tempos modernos, ques­tão que lhe parece outros existencialistas não haviam ainda resolvido. Neste texto também mostramos como o filósofo considera a superação da facticidade, o que dá especificidade à sua reflexão. A complexidade e criatividade de suas formulações nos mostram uma das muitas possibilidades do existencialismo, movimento que precisamos bem balancear neste início do século XXI porque ele traduz as inseguranças e incertezas do homem do último século.

Some of the most promising advances in recent social and sociological theory have happened in connection with historical sociology, including the ‘multiple’ or ‘entangled’ modernity as well as the civilizational approaches, despite their several problems. This article critically resumes this debate, proposing specific conceptualizations of civilization and modernity, at the global level, as well as of regions. Multidimensionality and collective subjectivities and modernizing moves cut across the whole text. The discussion starts from a specific analysis of Latin American modernity, including (...) the criticism of some recent interpretations. It then moves into more general conceptual dimensions, taking Latin America in unitary terms and as a unit of analysis, regardless of its relative internal heterogeneity, and placing of the subcontinent within a comparative view of, in particular, a third, contemporary phase of modernity, vis-à-vis China, India, Africa and other civilizational coordinates.

Neste artigo, estudamos as características que o filósofo espanhol Ortega y Gasset atribuiu à vida. Mostramos que o essencial de sua meditação girou em torno do assunto. No entanto, o tema ganhou densidade metafísica somente no final dos anos 1920, quando suas considerações foram inseridas na tradição filosófica do ocidente. Foi quando ele apontou a insuficiência do realismo e do idealismo na abordagem do fundamento pretendido pela Filosofia e apresentou a filosofia da razão vital como um passo adiante das duas (...) grandes perspectivas filosóficas que marcaram a história da metafísica. In this article, we study the characteristics that the Spanish philosopher Ortega y Gasset attributed to life. We show that the essence of his meditations revolved around the subject. However, the issue gained metaphysical density only in the late 1920s, when his remarks were inserted into the philosophical tradition of the West. That is when he pointed out the failure of realism and idealism in the approach to foundations pretended by philosophy, and presented the philosophy of vital reason as a step forward from the two great philosophical perspectives that have marked the history of metaphysics.
