The aim of this paper is to investigate among a group of non-profit organizations: a) the effect of ethical leadership on volunteers’ satisfaction, affective organizational commitment and intention to stay in the same organization; b) the role played by job satisfaction as a mediator in the relationship between ethical leadership and volunteers’ intentions to stay in the same organization, as well as between ethical leadership and affective commitment. An anonymous questionnaire was individually administered to 198 Italian volunteers of different non-profit (...) organizations. The questionnaire contained the Ethical Leadership Scale, the Volunteers Satisfaction Index, the Affective organization Scale, as well as questions regarding the participants’ age, sex, type of work, level of education, length of their volunteer works, intention to volunteer in the following months in the same organization. The construct as well the effects of EL on volunteers is approached in light of the Social Exchange Theory and the Social Learning Theory. Structural equation models were used to test hypothesized relationships. The results confirm the role of mediation of volunteer satisfaction in the relationships between the variables studied. In particular, ethical leadership was found to be positively associated both with volunteers’ intention of staying and with their affective commitment. In the first case this relationship is fully explained by the mediation of the volunteers’ satisfaction, while the latter is explained by both direct and indirect factors. To the authors’ knowledge, this the first attempt to understand the role played by ethical leadership on volunteers’ behavior and, more in general, in the management of non-profit organizations. Findings are relevant both for practitioners and managers of non-profit organization, since they suggest the relevance of the perception of ethical leadership by volunteers, as well as for scholars, since they further deepen the knowledge on EL and its effects on the followers. Limits of the study: the questionnaire was administered only among a group of non-statistical sample of volunteers. Furthermore, the study reached only volunteers from Italian non-profit organization. (shrink)

Testimonio que recoge algunas experiencias y reflexiones de la artista visual costarricense María Rapela en Alemania y de cómo se involucró en la gestión cultural, coordinando el Fieber Festival, una plataforma colaborativa y auto-gestionada de mujeres artistas migrantes iberoamericanas en Berlín entre el 2011 y el 2017.

Enrique Leff sostiene que las causas profundas de la crisis ambiental se basan en formas dominantes de conocimiento, es decir, la crisis tiene sus raíces en las bases epistemológicas de la modernidad. Leff sistemáticamente se ha dedicado a proponer y construir conceptos que deconstruyen los supuestos modernos, y que al mismo tiempo, permiten nuevas formas de entender y aprehender el mundo. Su extensa obra ha logrado trascender y forjar un espacio para el pensamiento ambiental, no sólo en la educación y (...) la filosofía ambiental, sino también en las áreas de la economía, la sociología y el desarrollo. Su argumento central es que estos problemas son el resultado de una crisis de la civilización, e insta a todos a repensar los fundamentos de la racionalidad moderna que subyace a la sociedad global contemporánea.

El propósito de este trabajo es mostrar, primero, cómo se formaron las ciencias sociales, con qué características y presupuestos, y comprender sus dificultades para entender y abordar los problemas ambientales. En un segundo momento se presentarán unas reflexiones en torno al conocimiento y su relación con el ambiente, así como la importancia de superar la escisión entre las llamadas ciencias duras y las sociales/humanas, y la necesidad de aportes como los de las ciencias de la complejidad, de los estudios culturales, (...) de modernidad/colonialidad, y del pensamiento ambiental, como desafíos y posibilidades para abordar el problema ambiental de manera integral. Este conjunto de aproximaciones representa un reto grande para las ciencias sociales, pero sin enfrentarlo será imposible abordar los problemas ambientales de manera adecuada. (shrink)

Los derechos sociales no han estado incorporados en las Comunidades Europeas, sino como consecuencias de la libre circulación de personas. Poco a poco a través de la política social se han ido asumiendo exigencias sociales que han desembocado en la formulación de derechos sociales denominados hoy "derechos de la solidaridad" en la Carta de Derechos Fundamentales de la Unión. No obstante, su efectividad y su justicialidad continúan siendo un interrogante y expresión del déficit de la U.E.

This article rereads some of Kant’s writings considered as pre-critical. It tries to investigate how in them the reflection about knowledge progressively takes a new direction against dogmatic positions. In order to do this, this article focuses on some of its specific aspects. We cannot assimilate these works to the revolution that the KrV will signify but we can read them as a preparation for that critical field. We share those interpretations which think that there is more continuity than breaking (...) off between the Kant considered pre-critical and his deployment clearly critical. (shrink)

Diese Studie der Deskription bei Franz Brentano lässt dessen Philosophie als ein «Programm der Deskription» erscheinen, das einen spezifischen Beitrag zur Gottesfrage leistet. Im Gegensatz zur scholastischen Tradition stellt er diese Frage auf sprachlicher Ebene und sucht dadurch erkenntnistheoretisch-metaphysische Engführungen zu überwinden. Er betont die deskriptive (nicht physikalische oder metaphysische) Bedeutung der Kausalität in ihrer Zeitgebundenheit und zeigt, dass die Existenz Gottes zeitlich bestimmt werden muss: Nur so ist eine sinnvolle Rede von Gott möglich. Brentanos Denken wurde in der Theologie (...) kaum wahrgenommen, aber die deskriptive Lösung des Problems von «esse et essentia», die Arten der Zeitlichkeit, die Betrachtung von Analogielehre und Univozität sind richtungsweisend.

São cento e cinquenta os códices que António Ribeiro dos Santos legou à Real Biblioteca Pública da Corte. O cuidado posto na sua organização, a exaustividade com que o trabalho foi executado, a sucessão de originais, cópias e borrões fazem deste núcleo documental uma peça indispensável para compreender a intervenção pública e profissional de Ribeiro dos Santos, sobretudo no que se relaciona com a Real Biblioteca Pública, mas também o carácter e as opções filosóficas do autor. Os códices foram organizados (...) tendo em vista preservar a memória de uma vida. Corporizam um manancial informativo que em duzentos anos despertou pouca atenção, constatação que proporcionou espaço para reflectir sobre a obra de Ribeiro dos Santos, escalpelizando o conteúdo e a organização dos códices.

Ou como um manuscrito do século XVIII, que não mereceu a glória de ser publicado, constitui uma fonte documental de indesmentível interesse. Trata-se de um relato de viagem de Lisboa a Roma na segunda metade do século XVIII o qual, embora não corresponda à descrição de uma peregrinação, revela com clareza questões culturais e religiosas que atormentam o Portugal de setecentos. Um diário de viagem que ajuda a compreender, em parte, o rótulo de exótico que a Europa iluminada atribuía a (...) Portugal. Através de uma leitura atenta, conseguem identificar-se elos, à primeira vista imperceptíveis, valorizando o próprio documento e lançando pistas para situar e compreender figuras de relevo naquele período da história portuguesa. O presente relato, como acontece com a literatura de viagens em geral, atribui ao leitor a responsabilidade de perscrutar a intenção do autor. Discute-se ainda a autoria, origem e fins do manuscrito, um conjunto de elementos que explicam a importância do mesmo. (shrink)

At the centenary of the creation of Diary of a Newlywed Poet, this paper elaborates on its metaphysical discovery. Building on the relevant concepts of the poet's aesthetics, it discovers the search for meaning in the poems in the light of sensitive enrichment, the understanding of reality and the stimulation of the receiver's conscience. The study was performed in the triple sense of cultivation, term under which the poet held a theory of human development, as cultivation of sensitivity, intelligence and (...) conscience. (shrink)

O objectivo deste artigo é a exploração de duas perspectivas contrastantes das teses de Leibniz sobre a Vida Feliz: numa, a felicidade depende da razão iluminada e da compreensão. A razão e a sabedoria são os verdadeiros fundamentos da felicidade, e se alcançarmos essa “Ciência da felicidade”, encontrá-la-emos, sem qualquer dúvida. A outra perspectiva apresenta-nos a finitude humana, a confusão que rege muitas vezes a própria vida, a fraqueza da vontade e os limites da razão, como obstáculos para a felicidade (...) e a tranquilidade. Efectivamente, a verdadeira felicidade só se pode encontrar na “delectatio in felicitate alterius”, em suma, no amor a Deus. Estas diferentes perspectivas podem entender-se como o contraste entre uma felicidade ideal que todo o homem deseja e a realidade da condição humana e da sua indigência. (shrink)

O “programa fiduciário” de Polanyi desafia o ideal da racionalidade moderna de alcançar uma completa justificação de todas as crenças, submetendo-as a uma crítica prévia à sua aceitação. Este requisito é um dos malefícios que está na raiz de preconceitos filosóficos e científicos que Polanyi se propõe superar. Este artigo apresenta o confronto entre o “modelo linear” da justificação do conhecimento, a partir de um princípio absoluto, com a alternativa do “modelo circular” proposto por Polanyi. Não se trata de uma (...) circularidade viciosa, mas do reconhecimento de que os fundamentos do conhecimento radicam no compromisso pessoal e na atitude fiduciária, alicerces inegáveis de qualquer forma de conhecer. A alternativa proposta por Polanyi, de longa tradição filosófica, é, nos nossos dias, uma fonte de inspiração também para a hermenêutica contemporânea, com as suas noções de compreensão e interpretação.

Knowledge about eating habits is relevant for understanding the relations between diet, obesity and development of Chronic Non-Communicable Diseases. The storage of calories as body fat, mainly in the visceral subcutaneous adipose tissue, as consequence of hypercaloric diet poor in nutrients, is responsible for increasing sublinic inflammation and overloading the immune system. Diet plays an important role in reducing inflammation. In time of infectious pandemia, of the new corona virus (COVID-19), the food quality and nutritional status of Brazilians may interfere (...) in fighting this infection. Based on the literature, this article aims to discuss the Brazilians eating habbits and nutritional status. The data shows that Brazilian are gainning weight and tend to a diet poor in nutrient intake. Consequently this scenario favors the subclinical inflammation and the weakness of the immune response. We suggest that Brazilian Health Authorities pay attention to this issue. (shrink)

El objetivo principal de este trabajo es dar a conocer las reflexiones del filósofo alemán Robert Spaemann en torno al concepto de dignidad humana. Para ello, nos detendremos a considerar qué van antes, si los derechos humanos o la dignidad; los tipos de dignidad: ontológica y moral; así como los problemas que lleva consigo el concepto de dignidad humana. A continuación, abordaremos la argumentación de Robert Spaemann en torno a la dignidad en tres apartados: la capacidad de autotrascendencia del ser (...) humano, el ser potencialmente moral, y el poder representar a lo Absoluto.

This article provides an intellectual history of the status of wage earners as conceptualized within the natural law paradigm by European writers both on the Continent and in Britain. Historians of political discourse have mostly investigated the consequences of such a status for the political rights of labourers. This article shows that the crucial moves were made by different authors analysing the relation of servant to master either in the domestic sphere or in private contracts. The article further contends that (...) that resulting deeply ambiguous analyses implied a far from complete personal freedom for wage earners. This had a decisive impact on different visions of commercial society in early modern times, and left a significant legacy for moderns. ☆ Apart from a few changes and some abridgment, this essay is the first chapter of my forthcoming book Vite da servi. Figure del lavoro salariato dalla giurisprudenza naturale all’economia politica (Servants’ Lives: Figures of Paid Labour from Natural Law to Political Economy). I am much indebted to Matthew Armistead for translating it, and to Marco Geuna and Gabriella Silvestrini for commenting on an earlier draft. (shrink)

We introduce new proof systems for propositional logic, simple deduction Frege systems, general deduction Frege systems, and nested deduction Frege systems, which augment Frege systems with variants of the deduction rule. We give upper bounds on the lengths of proofs in Frege proof systems compared to lengths in these new systems. As applications we give near-linear simulations of the propositional Gentzen sequent calculus and the natural deduction calculus by Frege proofs. The length of a proof is the number of lines (...) in the proof. A general deduction Frege proof system provides at most quadratic speedup over Frege proof systems. A nested deduction Frege proof system provides at most a nearly linear speedup over Frege system where by "nearly linear" is meant the ratio of proof lengths is O) where α is the inverse Ackermann function. A nested deduction Frege system can linearly simulate the propositional sequent calculus, the tree-like general deduction Frege calculus, and the natural deduction calculus. Hence a Frege proof system can simulate all those proof systems with proof lengths bounded by O). Also we show that a Frege proof of n lines can be transformed into a tree-like Frege proof of O lines and of height O. As a corollary of this fact we can prove that natural deduction and sequent calculus tree-like systems simulate Frege systems with proof lengths bounded by O. (shrink)
