Purpose: Performance measurement systems (PMS) in Nonprofit Organizations (NPOs) are more complex than in for-profit organizations. NPOs have an orientation towards social mission and values, and they consider not only organizational efficiency and viability, but also the social impact of the organization. This research provides a comprehensive synthesis of PMSs in NPOs. Design/methodology/approach: Using a literature review, supported by bibliometric and network analyses. A paper set of 240 articles related to this research field is examined. Topics that are the most (...) prevalent in this research area and their interrelationships are identified, presenting an outline of current efforts. Findings: Despite the descriptive analyses for the paper set, a framework is proposed for organizing the design-implementation factors of PMSs in nonprofit organizations, identifying the main requirements for their successful development. Originality/value: Investigation on performance measurement in nonprofit organizations is still in its early stages of development with many opportunities to further develop the field. Conceptual frameworks and models, as well as specific theories, are being generated for this field of research, and the process of adapting models from the general field of performance measurement is taking place. The meta-framework that organizes the main research topics of PMS in nonprofit organizations and the framework that consolidates factors that influence the design-implementation of PMSs in nonprofit organizations developed represents this paper contribution.

The COVID-19 pandemic produced immeasurable impacts on the economy, education, and socialization, besides the loss of millions of lives. Thus, there has been an accelerated development of an unprecedented number of COVID-19 vaccine candidates to control the pandemic. The World Health Organization’s emergency use authorization of COVID-19 vaccines still in clinical trial allowed immunizing the population. This paper presents a perspective of the bioethical precepts of autonomy, non-maleficence, beneficence, and justice in the emergency use of COVID-19 vaccines. Furthermore, it emphasizes (...) the importance of surveillance at all stages of vaccine development to detect adverse effects and ensure compliance with bioethical precepts. (shrink)

A PARTIR DE UM DIÁLOGO COM ALGUMAS INTERPRETAÇÕES CONSAGRADAS DE NIETZSCHE, ESTE ARTIGO DEFENDE A CENTRALIDADE DA NOÇÃO DE INDIVÍDUO NO PERSPECTIVISMO NIETZSCHIANO, SUGERINDO COM ISSO A SUA FILIAÇÃO AO PROJETO CRÍTICO KANTIANO. TRATA-SE DE UMA LEITURA QUE SE DEIXOU INSPIRAR, EM GRANDE MEDIDA, NAS INTERPRETAÇÕES DE FRIEDRICH KAULBACH E ANTONIO MARQUES.

O desígnio do presente artigo é uma reflexão teórica, mais do que abordar a política da Psicanálise importa tratar da política frente a qual a Psicanálise precisa se posicionar, o que torna imprescindível, ao nosso ver, ir em busca dos escritos marxianos, visando aproximações. Na exposição que se apresenta, definimos o conceito de política à luz de “O 18 de Brumário de Luís Bonaparte”, do qual Marx assinalou uma leitura específica sobre a história. Todavia, lançamos mão da hipótese sustentada por (...) Lacan de que Marx “inventara o sintoma”, isto é, foi o primeiro a denunciar a espoliação de um gozo. (shrink)

This article examined the personal profiles of the Heads of Government of countries in South/North America and how they communicated with their audiences on institutional measures to contain COVID-19. Analyses were carried out on data collected from Twitter from November-2019 to November-2020. This study includes: i)quantitative analysis, measuring categories and emphases in the communication of tweets, retweets, likes, and comments on matters relevant to the pandemic; ii)qualitative analysis that allowed evaluating speeches to identify political interference and the effectiveness of communication (...) at critical moments of the pandemic. It was possible to infer that each president has his singularities and understanding about Social Media’s use as a more direct communication tool with his audience. It was also found that successful communication is not directly proportional to the volume of messages on Twitter, but to socio-political aspects and institutional leadership that can make a difference in Social Media in combating COVID-19.

Seja nos manuais de história da filosofia, seja em estudos mais especializados sobre Kant, estamos habituados a pensar a construção de sua filosofia crítica a partir de duas grandes linhas de influência: de um lado, a tradição metafísica leibniz-wolffiana, em que o filósofo se teria formado, e, de outro, o empirismo britânico, sobretudo Hume, que, segundo a conhecida explicação do próprio Kant, o teria acordado de seu sono dogmático. O mais novo livro de Marco Sgarbi, La “Kritik der reinen Vernunft” (...) nel contesto della tradizione logica aristotelica [A “Crítica da razão pura” no contexto da tradição lógica aristotélica], publicado em 2010 pela prestigiosa casa editorial Georg Olms, propõe tirar-nos a nós, estudiosos da obra kantiana, desse antigo “sono dogmático”: segundo sua tese fundamental, Kant seria tão ou mais devedor do aristotelismo quanto do leibniz-wolffianismo ou do empirismo humiano.

Resumo: Esse ensaio buscará sondar as relações entre filosofia e literatura, no pensamento de Gilles Deleuze, a despeito de sua parceria conjunta com Félix Guattari, atentando tanto para as concepções de escrita expressas ao longo de sua obra quanto para o modo como essas concepções teriam influenciado o estilo de seus escritos filosóficos. Partindo da premissa deleuziana de que a escrita possui um acentuado lastro clínico, sendo a responsável pela elaboração de um diagnóstico das forças capazes de aprisionar ou calar (...) a vida, procurar-se-á esmiuçar as ressonâncias desse lastro clínico, na concepção de filosofia como ato criativo, elaborada pelo autor. Como hipótese a ser aqui trabalhada, defende-se que a escrita deleuziana - compreendida como portadora de uma literalidade, conforme sustenta François Zourabchivili, ou como encrustada de uma poética imanentista, tal qual sugere Anita Costa Malufe - procuraria produzir uma zona de vizinhança ou indiscernibilidade entre a escrita filosófica, de caráter mais exegético, e a escrita literária, mais afectiva, de modo a produzir um deslocamento na relação do leitor com o ato de pensar.: In this essay we pretend to study the relationship between philosophy and literature in Gilles Deleuze’s thought, despite of his partnership with Félix Guattari, mapping the conceptions of writing throughout his work and considering the influence of these conceptions to forge a certain style in his philosophical texts. Starting from the deleuzian premise that writing has a strong clinical backing - being responsible for the elaboration of a diagnosis of the forces liable to imprison or silence life -, we will examine the resonances of this clinical backing in his conception of philosophy as a creative act. Our hypothesis is that the deleuzian writing - having a certain literality, as François Zourabchivili argues, or encrusted with an immanentism poetics, as Anita Costa Malufe suggests - would produce a so-called neighborhood zone or zone of indiscernibility between philosophical writing, with a more exegetical character, and literary writing, which is more affective, in order to produce a shift in the reader’s relationship with the act of thinking.

Neste artigo, a partir de tópicos presentes na obra de Newton C. A. da Costa, propomos uma fundamentação rigorosa para de uma possível formulação de teorias científicas através da abordagem semântica. Seguindo da Costa, primeiramente desenvolveremos uma teoria geral das estruturas; no contexto desta teoria de estruturas mostraremos como caracterizar linguagens formais como um tipo particular de estrutura, mais especificamente, como uma álgebra livre. Em seguida, discutiremos como associar uma linguagem a uma estrutura, com a qual poderemos formular (...) axiomas que buscam captar a teoria da estrutura. Por fim, mostraremos como podemos, utilizando este aparato conceitual, fundamentar a formalização de da Costa e Chuaqui do chamado predicado de Suppes, utilizado para caracterizar teorias científicas de modo rigoroso.

In this paper, gathering several topics present in the work of Newton da Costa, we propose a rigorous foundation for a possible formulation of scientific theories according to the semantic approach. Following da Costa, as a first step we develop a general theory of structures; inside this theory we show how we can characterize formal languages as particular kinds of structures, more specifically, as free algebras. Next we discuss how we can link a language to a structure, with (...) which we can formulate the axioms that are intended to capture the theory of the structure. Finally, we show how we can, employing the framework developed, formulate da Costa and Chaqui’s formalization of the so-called Suppes’ Predicate, used to characterize scientific theories in a rigorous way. • DOI:10.5007/1808-1711.2010v14n1p15.

En palabras de la Dra. Ivana Costa, la argumentación que aquí se propone lleva a los lectores a descubrir en la teoría epicureísta de las pasiones el fundamento de la filosofía política epicúrea [...]. Pero el eje de esta teoría está, indudablemente, en la caracterización que hace Epicuro del placer; esto es, la determinación precisa de qué lugar le cabe [...] entre los bienes para la buena vida [y] qué credenciales tiene para ser considerado el bien supremo. Este fue (...) uno de los temas centrales del debate ético-político que plantearon las diferentes líneas filosóficas en Grecia entre fines del siglo V a.C. y comienzos del siglo IV a.C. [...] Epicuro intentaba demostrar [...] que la justicia, entendida como virtud individual, se identifica con el placer, a contracorriente de la communis opinio, que la concibe destinada al beneficio de los demás. Al identificar a la virtud de la justicia con la ataraxia, al concebirla como virtud que es también capaz de "tranquilizar" con eficacia a quien la posee y la practica (porque es precisamente su contrario, la injusticia, la que provoca la turbación del alma), la noción epicúrea de justicia queda unida también a su singular teoría del placer. Que no es mero disfrute personal sino actividad que extirpa las opiniones equivocadas y las sustituye por estados mentales verdaderos y adecuados. La investigación que da origen a este libro había mostrado, con sólidas herramientas de análisis de las fuentes y exhaustiva discusión de la literatura sobre el tema, que el concepto epicúreo de justicia no puede escindirse del entramado de la lógica, la física y la ética del maestro de Samos. [...] Se parte entonces de esa trama compleja y, con delicadeza y generosidad, la argumentación va deshilvanando los motivos que han llevado tradicionalmente a una interpretación convencionalista o naturalista de la filosofía epicúrea. Finalmente, señala que el profesor Navarro nos propone considerar el concepto de justicia subrayando la posición excéntrica que insinúa Epicuro respecto de la contraposición nómos-phýsis en la que se venía dirimiendo la cuestión desde finales del siglo V a.C. El análisis [...] abre a la posibilidad de una reconstrucción global de la filosofía política epicúrea [y] permite reformular, a partir del eje naturaleza-convención, tanto su teoría física, como su gnoseología [...]. En cuanto a los aspectos específicamente políticos de la filosofía de Epicuro, la argumentación va, de los comienzos de la asociación humana, al estatuto de las leyes, el progreso de la historia y el papel de la prólepsis como criterio de lo justo.

In this paper we discuss two approaches to the axiomatization of scientific theories in the context of the so called semantic approach, according to which (roughly) a theory can be seen as a class of models. The two approaches are associated respectively to Suppes’ and to da Costa and Chuaqui’s works. We argue that theories can be developed both in a way more akin to the usual mathematical practice (Suppes), in an informal set theoretical environment, writing the set theoretical (...) predicate in the language of set theory itself or, more rigorously (da Costa and Chuaqui), by employing formal languages that help us in writing the postulates to define a class of structures. Both approaches are called internal , for we work within a mathematical framework, here taken to be first-order ZFC. We contrast these approaches with an external one, here discussed briefly. We argue that each one has its strong and weak points, whose discussion is relevant for the philosophical foundations of science. (shrink)

Da Costa and French explore the consequences of adopting a 'pragmatic' notion of truth in the philosophy of science. Their framework sheds new light on issues to do with belief, theory acceptance, and the realism-antirealism debate, as well as the nature of scientific models and their heuristic development.

The mathematical concept of pragmatic truth, first introduced in Mikenberg, da Costa and Chuaqui (1986), has received in the last few years several applications in logic and the philosophy of science. In this paper, we study the logic of pragmatic truth, and show that there are important connections between this logic, modal logic and, in particular, Jaskowski's discussive logic. In order to do so, two systems are put forward so that the notions of pragmatic validity and pragmatic truth can (...) be accommodated. One of the main results of this paper is that the logic of pragmatic truth is paraconsistent. The philosophical import of this result, which justifies the application of pragmatic truth to inconsistent settings, is also discussed. (shrink)

An introduction to the model-theoretic approach in the philosophy of science is given and it is argued that this program is further enhanced by the introduction of partial structures. It is then shown that this leads to a natural and intuitive account of both "iconic" and mathematical models and of the role of the former in science itself.

Physical superpositions exist both in classical and in quantum physics. However, what is exactly meant by ‘superposition’ in each case is extremely different. In this paper we discuss some of the multiple interpretations which exist in the literature regarding superpositions in quantum mechanics. We argue that all these interpretations have something in common: they all attempt to avoid ‘contradiction’. We argue in this paper, in favor of the importance of developing a new interpretation of superpositions which takes into account contradiction, (...) as a key element of the formal structure of the theory, “right from the start”. In order to show the feasibility of our interpretational project we present an outline of a paraconsistent approach to quantum superpositions which attempts to account for the contradictory properties present in general within quantum superpositions. This approach must not be understood as a closed formal and conceptual scheme but rather as a first step towards a different type of understanding regarding quantum superpositions. (shrink)

We investigate the higher-order modal logic , which is a variant of the system presented in our previous work. A semantics for that system, founded on the theory of quasi sets, is outlined. We show how such a semantics, motivated by the very intuitive base of Schrödinger logics, provides an alternative way to formalize some intensional concepts and features which have been used in recent discussions on the logical foundations of quantum mechanics; for example, that some terms like 'electron' have (...) no precise reference and that 'identical' particles cannot be named unambiguously. In the last section, we sketch a classical semantics for quasi set theory. (shrink)

The issue of what consequences to draw from the existence of non-classical logical systems has been the subject of an interesting debate across a diversity of fields. In this paper the matter of alternative logics is considered with reference to a specific belief system and its propositions :the Azande are said to maintain beliefs about witchcraft which, when expressed propositionally, appear to be inconsistent. When the Azande have been presented with such inconsistencies, they either fail to see them as such (...) or else accept them as non-problematical. Is our knowledge of logical truths a relative and culturally determined phenomenon, or is there some (transcendent) criterion that allows us to adjudicate between alternative logical systems? The authors propose an approach for resolving disputes about the status of Azande reasoning which assumes a paraconsistent framework, thus providing a new perspective on this debate. (shrink)

This paper is concerned with the particular problems raised by observations of phenomena outside the common course of nature for their validation as knowledge. It examines to what extent the content of the reports and, in particular, their lack of intrinsic plausibility affected the methods used in their authentication and the assessment of testimony at the Royal Society in the first half of the eighteenth century. I show that literary strategies were usually necessary but not sufficient for the validation of (...) these kinds of observations. Next, I discuss why visual representations were especially useful in establishing the singularity of the observations, but I point out that their high costs and other restrictions meant that they were not so widespread. In contrast I show that, for a long period of time, testimony was used in the majority of the reports as the true stamp of authenticity. I note, however, that the Royal Society accepted reports by authors of varied social status, level of education and occupation, and I discuss some of the factors responsible for the complexity of the handling of testimony at the Society. I argue against Shapin that in the case of reports of extraordinary phenomena, the competence of the reporter and witnesses was often more important than their social status. The increasing role of expertise in the assessment of observations at the Society become especially apparent by the middle of the eighteenth century.Author Keywords: Authentication; Competence; Monstrous births; Singular; Testimony; Royal Society of London.

This paper seeks to provide an approach for achieving a more socially and environmentally sustainable life by reframing the rules of engagement with the planet and with each other by setting minimum standards on essential criteria i.e., by defining “off-limits”zones for corporate action. For a more humanistic and socially just way of living life that would sustain the planet, a set of moral boundaries that cannot be breached are conceived. We offer a set of possible normative leverage points that must (...) not be violated by business in the long-term. Our paper takes a forward-looking view beyond the current generational targets for sustainability. We operate on the premise that sustainability involves preserving the future generations of the planet in both an environmental and human sense. The Moral Boundaries for Business framework embraces the Seventh Generation Principle. The moral boundaries we offer in this paper, if followed, are meant to have positive implications for humanity and the planet in the next seven generations. (shrink)

In this paper we will present the philosopher Friedrich Nietzsche’s main reflections on the scientific enterprise, its relation to the metaphysical tradition, and how the German author drew on the nineteenth century cosmological discussion to develop a worldview that ultimately endorses a dynamic and more creative form of science, whose representations and values should not be separated from human interests.

We formulate Suppes predicates for various kinds of space-time: classical Euclidean, Minkowski's, and that of General Relativity. Starting with topological properties, these continua are mathematically constructed with the help of a basic algebra of events; this algebra constitutes a kind of mereology, in the sense of Lesniewski. There are several alternative, possible constructions, depending, for instance, on the use of the common field of reals or of a non-Archimedian field (with infinitesimals). Our approach was inspired by the work of Whitehead (...) (1919), though our philosophical stance is completely different from his. The structures obtained are idealized constructs underlying extant, physical space-time. (shrink)

We discuss the hypothesis that the debate about the interpretation of the orthodox formalism of quantum mechanics might have been misguided right from the start by a biased metaphysical interpretation of the formalism and its inner mathematical relations. In particular, we focus on the orthodox interpretation of the congruence relation, '=', which relates equivalent classes of different mathematical representations of a vector in Hilbert space, in terms of metaphysical identity. We will argue that this seemingly "common sense" interpretation, at the (...) semantic level, has severe difficulties when considering the syntactic level of the theory. (shrink)

In this paper we make some general remarks on the use of non-classical logics, in particular paraconsistent logic, in the foundational analysis of physical theories. As a case-study, we present a reconstruction of P.\ -D.\ F\'evrier's 'logic of complementarity' as a strict three-valued logic and also a paraconsistent version of it. At the end, we sketch our own approach to complementarity, which is based on a paraconsistent logic termed 'paraclassical logic'.

Este artigo dialoga com autores que estudam a temática juventude e escola, problematizando a função da escola como locus de socialização. Parte do pressuposto de que muitos problemas enfrentados pelos jovens na escola é resultado de uma realidade em que as culturas juvenis, caracterizadas por determinadas formas de comportamento, como, gostos, atitudes, estilo de vida, forma de ser, vestir, dançar, falar, se divertir e se relacionar não podem se fazer presentes. Em virtude disso, analisa a desarticulação da escola com as (...) perspectivas dos jovens, ao acharem-na desinteressante por não contemplar seus anseios e suas necessidades e tampouco reconhecer a realidade em que estão inseridos. Parte da concepção de que a escola deve contemplar espaços e situações que promovam experiências de sociabilidade.

Procuramos expor o pluralismo de leituras da obra freudiana mediante a exploração da hipótese de historicização da formação psíquica dos sujeitos, especialmente relativa ao complexo de Édipo e Supereu. Partindo da perspectiva de estudos feministas, verificamos no corpus teórico freudiano se há a possibilidade de que o avanço sócio-histórico seja um fator de modificação de concepções que, na leitura freudiana clássica, seriam lidas como imutáveis, fixas e rígidas cultural e historicamente. Madelon Sprengnether, Nancy Chodorow e Judith Butler serão retomadas para (...) criticar a leitura clássica e generalizante do complexo de Édipo enquanto “estrutural”, essencializado e substancializado. Sugerimos que, sendo uma lei hegemônica, a vivência edípica não pode ser completamente ultrapassada, mas pode ser performativamente atuada de formas desviantes de sua estrutura classicamente pensada por Freud. Nesse âmbito, a transmissão geracional é nosso enfoque primordial. Ela é debatida ao menos em três momentos complementares: na análise da filogênese, da herança arcaica e do Édipo social exposta em Totem e tabu, na herança narcísica de expectativas e ideais compreendida em Introdução ao narcisismo e na teoria da perpetuação de valores e tradições morais via identificações geracionais superegoicas que consta nas Novas Conferências sobre Psicanálise.

The apparently paradoxical nature of self-deception has attracted a great deal of controversy in recent years. Focussing on those aspects of the phenomenon which involve the holding of "contradictory" beliefs, it is our intention to argue that this presents no "paradox" if a non-classical, "paraconsistent", doxastic logic is adopted. (On such logics, see, for example, N. C. A. da Costa, 'On the theory of inconsistent formal systems', Notre Dame J Formal Logic 11(1974), 497-510, and A. I. Arruda, 'A survey (...) of paraconsistent logic', in A. I. Arruda, N. C. A da Costa and R Chuaqui, _Mathematical Logic in Latin America, North-Holland, 1984, pp. 1-41.). (shrink)

Our objective will be to argue in favor of the idea that in Nietzsche there is no genealogical method, stricto sensu, with universalist and systemic-substantivist epistemic claims (traditionally conceived by justificationist and foundationalist philosophies from Plato to Hegel). However, there is a characteristic genealogical program, which opposes the majority genealogies and philosophies insofar as a self-suppression of the method is imposed as the primary and heterodox register of its reflection. We start from the hypothesis that Nietzsche’s genealogy, understood programmatically, became (...) viable because it was markedly structured on the basis of three reflexive movements that free his genealogical thinking from an analytical-methodological conduct, like the canon, which are: (i) variation of style in his writing; (ii) critical historicism or radical and (iii) discontinuity of origin. However, it would be pointless to show how clearly the Nietzschean genealogical program was outlined if we couldn’t say where it came from, for whom and for what purpose, or even more so, what it is intended to denounce. Therefore, in our conclusion, we will show, with some reservation, how the Nietzschean genealogical program lends itself to evaluating the dimension of power. (shrink)

The partial structures approach has two major components: a broad notion of structure (partial structure) and a weak notion of truth (quasi-truth). In this paper, we discuss the relationship between this approach and free logic. We also compare the model-theoretic analysis supplied by partial structures with the method of supervaluations, which was initially introduced as a technique to provide a semantic analysis of free logic. We then combine the three formal frameworks (partial structures, free logic and supervaluations), and apply the (...) resulting approach to accommodate semantic paradoxes. (shrink)

In this paper, we provide a new formulation of a coherence theory of truth using the resources of the partial structures approach − in particular the notions of partial structure and quasi-truth. After developing this new formulation, we apply the resulting theory to the philosophy of mathematics, and argue that it can be used to develop a new account of nominalism in mathematics. This application illustrates the strength and usefulness of the proposed formulation of a coherence theory of truth.Neste artigo, (...) propomos uma nova formulação de uma teoria coerentista da verdade utilizando os recursos da abordagem de estruturas parciais - em particular as noções de estrutura parcial e quase-verdade.

In view of the present state of development of non classical logic, especially of paraconsistent logic, a new stand regarding the relations between logic and ontology is defended In a parody of a dictum of Quine, my stand May be summarized as follows.
