Social networks play a significant role in learning and thus in farmers’ adoption of new agricultural technologies. This study examined the effects of social network factors on information acquisition and adoption of new seed varieties among groundnut farmers in Uganda and Kenya. The data were generated through face-to-face interviews from a random sample of 461 farmers, 232 in Uganda and 229 in Kenya. To assess these effects two alternative econometric models were used: a seemingly unrelated bivariate probit model and a (...) recursive bivariate probit model. The statistical evaluation of the SUBP shows that information acquisition and adoption decisions are interrelated while tests for the RBP do not support this latter model. Therefore, the analysis is based on the results obtained from the SUBP. These results reveal that social network factors, particularly weak ties with external support, partially influence information acquisition, but do not influence adoption. In Uganda, external support, gender, farm size, and geographic location have an impact on information acquisition. In Kenya, external support and geographic location also have an impact on information acquisition. With regard to adoption, gender, household size, and geographic location play the most important roles for Ugandan farmers, while in Kenya information from external sources, education, and farm size affect adoption choice. The study provides insight on the importance of external weak ties in groundnut farming, and a need to understand regional differences along gender lines while developing agricultural strategies. This study further illustrates the importance of farmer participation in applied technology research and the impact of social interactions among farmers and external agents. (shrink)

Considering liberty as a social notion implies the adoption of both an innovative method and style. With this aim in mind, Axel Honneth provides a fresh outlook on notions typically found with Hegel, Marx, Dewey, or Habermas. At last, inspired by psychoanalysis, he pioneers fruitful and unprecedented social therapeutics.

The present article is devoted to two issues. The first is the identification of lead and tin in medieval Arabic alchemy. The second is the investigation of whether Arabic alchemists differentiate between these problematic substances or not. These two issues are investigated in the light of a comparison which is made between the facts that are stated about the two problematic substances in the original Arabic alchemical works and those stated in modern chemical literature. It is proved that Arabic alchemists (...) made a sharp distinction between lead and tin. Also, it becomes clear that these two metals were used in a satisfactory purity in the era of medieval Arabic alchemy. As a consequence of the present study, some conclusions are drawn about the existence of some categories of ‘derivatives’ of fusible bodies in Arabic alchemy which are degenerate to modern categories of oxides, carbonates, etc. (shrink)

The history of organizations and collectives is something alive. It is a network of memories, actions, collaborations, dreams, encounters, and disconnections that live within each of its members. The EcoDialogue Center is an academic space of the University of Veracruz for promoting dialogue between disciplines. In this article we are presenting the stories, both personal and collective, and the values and ideals that create our Center. We are using this opportunity to reflect on the cultural, geographical, emotional, intellectual, and societal (...) conditions that have allowed this innovative process within the rules and customs of a university.

O objetivo deste artigo é analisar as relações entre agnotologia (construção social da ignorância) e o princípio da precaução (PP) sob dois aspectos. O primeiro diz respeito à crítica de que parcela dos defensores do PP teria utilizado estratégias de construção de ignorância. A partir do trabalho do filósofo Daniel Steel, mostro como elas enfraquecem um critério interno ao próprio princípio: a proporcionalidade. Sob o segundo aspecto, comento documentos tornados públicos que evidenciam estratégias de agnotologia por setores da indústria tanto (...) sobre o PP como sobre resultados científicos para que ele não fosse aplicado. Semelhante exposição ainda não foi realizada na literatura especializada no PP. A partir dessa análise, busco contribuir para identificar estratégias de agnotologia em debates sobre o PP. (shrink)

The need for the axiological determinants of cognition of law to be theoretically justified as a constituent of legal progress that includes the humanization of law makes the problem under the study relevant. The purpose of this article is to distinguish the value determinants of cognition of law. The main methodological approaches used in the study are axiological and anthropological approaches, which allow us to consider law as a valuable constituent of human life, inextricably linked with the human personality. The (...) article reveals that the modern understanding of the term “law” is characterized by axiological and anthropological approaches to its cognition; founds out that the human legal value has an integral-synthesizing character to all other values and, as a result, is embodied in the absolute legal value and inherent worth; establishes that the human dimension of law has become the result and, at the same time, the source of value-legal human understanding, which indicates the value of law and its axiological characteristics.

Defensores do princípio da precaução propõem com frequência mudanças nas práticas científicas, para que elas facilitem o mesmo objetivo do princípio: evitar ameaças incertas ao ambiente ou à saúde humana. A ciência deveria ser uma ciência precautória. Apesar da importância prática da ciência precautória e da sua proximidade com os debates sobre ciência e valores, ela ainda não foi sistematicamente examinada. Neste artigo, pretende-se contribuir para a literatura sobre a ciência precautória de dois modos: sistematizando sua literatura prévia e propondo (...) uma definição de um de seus elementos principais, a precaução epistêmica, como uma orientação específica para a gestão de riscos indutivos. Conclui-se com algumas objeções que tal definição levanta, bem como caminhos de pesquisas futuras para abordá-las. (shrink)

Primeiramente, oferecemos uma apresentação teórica da representação do pensamento prático, começando pela distinção entre silogismo dialético e silogismo demonstrativo. Fazemos referência à crítica de Toulmin contra o dedutivismo dominante de seu tempo. Em seguida, fornecemos argumentos para apoiar a relevância heurística do modelo de Toulmin para entender a discussão sobre a inclusão da lógica padrão na representação do pensamento comum. Afirmamos que o projeto analítico toulmaniano permite entender, com clareza metódica, a derrotabilidade dos argumentos do senso comum por meio da (...) investigação da noção modal de probabilidade na linguagem comum. First, we offer theoretical resemblance of the representation of practical reasoning, beginning with the distinction between demonstrative and dialectical syllogism. We make reference to the Toulmin’s critique against to the dominant deductivism in his time. Then we give arguments to sustain the heuristic relevance of Toulmin’s model to understand the discussion about the inclusion of default logics in the representation of ordinary reasoning. We assert that the Toulminian analytic design allows to understand, with methodical clarity, the defeasibility of common sense arguments by means of the investigation of the modal notion of probability in ordinary language.

Este ensayo describe una particular experiencia estética, basada en la obra gráfica La confianza, de Goya, perteneciente a la serie de los Caprichos e invenciones, que son paisajes de pesadilla que ilustran la crisis social de la época de las Luces. Desde aquí, desarrollaré una hermenéutica personal que avanza por tres escenarios teóricos sobre lo que implicaría la confianza de una mujer en otra, a partir del soporte de imagen. Las diversas tesis teóricas se sitúan en la órbita del pensamiento (...) feminista de actualidad y en donde se representarán a tres autoras: Muraro, Despentes y Braidotti. Finalmente, este dispositivo de interpretación permitirá relevar el arte de Goya a propósito de una posible revisión de crítica social sobre la virtud de la confianza. (shrink)

Resumen En este trabajo se reflexiona, en primer término, acerca del valor como categoría analítica de las estrategias de cortesía atenuadora. Se sostiene que, para interpretar que se ha producido una atenuación, es necesario identificar la actividad comunicativa que se evalúa como amenazante en ese contexto. Una estrategia de cortesía atenuadora se define como aquella cuya función es disminuir el efecto social negativo que pueda tener una actividad de imagen amenazante en el estado de la relación interpersonal y en el (...) clima socio-emocional de la interlocución en curso. Con base en Bravo proponemos un modelo para la interpretación de este tipo de estrategias en su contexto de producción. En segundo término, queremos hacer un aporte al estudio de las estrategias de cortesía atenuadora, planteando las dificultades que se le presentan al/la analista a la hora de registrar este tipo de actividades de imagen en discursos públicos en los cuales el nivel de conflicto interlocutivo es elevado. Se concluye que, si bien priman las estrategias de autoimagen y las de descortesía, la atenuación matiza la confrontación en beneficio de la construcción de una identidad de imagen acorde con las expectativas de diferentes auditorios.

This paper examines two contemporary answers to the question of whether moral values and norms are apt for rational criticism and justification: Richard Rorty’s radically contextualist approach—which is centered around the notion of contingency and is characterized by a dismissal of all claims to philosophical justification—and Karl-Otto Apel’s transcendental-pragmatic version of discourse ethics—which encompasses highly ambitious claims to justification and universal validity. Contrasting the key theses of Rorty’s contextualism with those of Apel’s universalist discourse ethics and reconstructing their respective conceptions (...) of moral progress we argue that neither Rorty’s nor Apel’s position is convincing.

"Qu'est-ce que le droit?" est peut-être la plus essentielle des problématiques auxquelles les juristes doivent répondre. Or peu de questions touchant à l'homme et aux sociétés ont suscité des réponses aussi diverses et parfois antagonistes que "Qu'est-ce que le droit?". Dans le vaste paysage des théories juridiques, il est difficile de savoir avec précision ce qu'est le droit. Faut-il dès lors se résigner à ne jamais disposer d'un objet-droit homogène et stable, dont l'identité serait finement établie et les frontières nettement (...) tracées? Pour étudier le droit, il importe pourtant de connaître ses spécificités parmi les différents modes de régulation sociale, cela afin de délimiter le champ des normes juridiques et donc circonscrire et borner l'objet d'étude. La définition du droit exposée dans la première partie de ce livre est une définition lexicographique, une définition scientifique. Il s'agit de constater ce qu'est le droit, quelles sont ses propriétés, au terme d'une enquête objective et empirique, excluant tout jugement subjectif et toute proposition personnelle. Comme la religion romaine qui accueillait dans son Panthéon tous les dieux grecs et étrusques, la théorie syncrétique réunit toutes les définitions du droit actuellement en vigueur dans la pensée juridique. Dans ce cadre, les diverses théories du droit ne sont plus des concurrentes, mais des associées. Elles ne s'opposent plus, mais se complètent. Ensuite, en appliquant les critères de juridicité ainsi recensés à une norme donnée, on peut mesurer son niveau de force juridique sur l'échelle de juridicité. Cette échelle, expliquée et expérimentée dans la seconde partie du livre, permet d'interroger les dimensions du droit. Or son application à de multiples formes de normativité indique que, dans le monde des normes sociales, les normes fortement juridiques côtoieraient les normes moyennement juridiques et les normes faiblement juridiques. En revanche, il ne semble guère exister de normes sociales non juridiques - les différences entre normes seraient de degré et non de nature. Ainsi l'échelle de juridicité invite-t-elle à retenir une conception graduelle du droit et un panjuridisme modéré. L'intérêt de cette nouvelle forme de rationalité de la pensée juridique est d'autoriser le juriste à s'ouvrir à tout type de normes sociales tout en sauvegardant l'autonomie conceptuelle du droit.

Drawing from cognitive learning theories we hypothesize that exposure to nationalistic appeals that suggest consumers should shun foreign brands for moral reasons increases the general belief in consumers that buying foreign brands is morally wrong. In parallel, drawing from the theory of psychological reactance we posit that such appeals may, against their communication goal, increase the reputation of foreign luxury brands. We term the juxtaposition of these apparently contradictory effects the “Ambivalence Hypothesis.” Further, drawing from prior research on source-similarity effects (...) we posit that foreign luxury brands that communicate cultural proximity to target consumers (i.e., a local brand positioning) reinforce psychological reactance (“Clean Conscience Hypothesis”). We test these hypotheses experimentally in the context of luxury car brand advertising in China, a market that is heavily dominated by foreign brands, and therefore provides a breeding ground for ambivalent consumer reactions. Results show that exposure to nationalistic appeals enhances consumers’ national identity dispositions (patriotism, local identity), which results in higher levels of consumer ethnocentrism. Further, nationalistic appeals enhance the social responsibility associations that consumers hold for foreign luxury brands and their countries of origin, which results in a higher brand reputation. Finally, effects of nationalistic appeals on foreign luxury brand reputation are positively stronger for brands using a local vs. a foreign or a global positioning. These findings suggest that nationalistic appeals are a double-edged sword with important implications for ethics in political communication and luxury brand marketing. (shrink)

RESUMEN La poesía de William Wordsworth pasaba por ser, entre muchos de sus comentaristas contemporáneos, una poesía pensante. Ya sea que se hablase de un sentido edificante de su poesía, de una perspectiva refrescante acerca de las cosas cotidianas o bien de un pensamiento filosófico, la poesía de Wordsworth siempre fue considerada como un notable esfuerzo por elevar el poema a una categoría ontológica. Dentro de este contexto, la imaginación cobra una gran importancia. Se analiza en qué sentido la imaginación (...) es el centro ontológico de la poesía de Wordsworth. ABSTRACT William Wordsworth's poetry was a thinking poetry, according to many of his contemporaries. Whether it was due to the edifying nature of his poetry, his refreshing approach to everyday things, or his philosophical thought, Wordsworth's poetry was always considered as a notable effort to elevate the poem to ontological category. In this context, imagination acquires great importance. The article analyzes the sense in which imagination is the ontological center of Wordsworth's poetry.

This text is a polemic against the 2023 article by Sergey N. Gradirovsky who wrote about the present-day relevance of Immanuel Kant’s concept of enlightenment and challenged the idea of the modern human being as a child who needs an external guardian or guide to control his behaviour. In my polemic with Gradirovksy I point out that in addition to “self-incurred immaturity” Kant writes about the historical “immaturity” of savage or backward peoples. I also argue that for Kant “maturity” carries (...) not only biological but also socio-historical connotations. I show that in the modern world Kant’s idea of the social or even historical maturity of the modern human acquires serious problematisation which was shown to be possible and inevitable in the article “What Is Enlightenment?” (1784) and its notion of the historicity of enlightenment, i.e. the very strategy of modernity is possible only when humankind reaches a certain historical age. Using as a point of departure the ideas of the French philosopher Michel Foucault, I maintain that the Kant­ian conception of enlightenment is at once ironic and tragic. It is ironic because it does not rule out that its main thesis on the historical maturity of the human being may turn out to be wrong. It is tragic because its main thrust is “heroisation of the present”, i.e. a readi­ness to resist the temptation of being absorbed by the future, which takes on added relevance in view of the virtualisation of reality.

Si tout le propos de Kant, dans la Critique de la raison pure, est de légitimer les conditions de possibilité des jugements synthétiques a priori, il ne va pas s'agir pour nous, à travers la présente étude, de prendre pour objet de recherche les conditions de possibilité des jugements synthétiques a priori, mais de nous attarder sur l'idée même de synthèse a priori et d'ouvrir une discussion critique autour du problème du jugement qui lui est directement rattaché. L'idée même de (...) synthèse a priori inaugure chez Kant une nouvelle forme de connaissance ; or toute forme de connaissance semble toujours consubstantiellement liée à une forme de jugement, car émettre un jugement revient à participer d'un acte de connaissance au travers duquel on détermine un rapport entre concepts. Tenter ainsi de montrer comment l'idée kantienne de jugement synthétique a priori, nouvelle manière de comprendre les relations entre concepts déterminés et de concevoir un jugement, fait problème en elle-même constituera également notre objet de recherche"--Page 4 of cover.

Non è un caso che l’enhancement umano, cioè il potenziamento di capacità fisiche, cognitive ed emotive degli esseri umani con l’ausilio di tecnologie, sia diventato un tema centrale nei dibattiti etico-applicativi e nei tentativi contemporanei di arrivare a una comprensione più adeguata della natura umana. In esso si incontrano quesiti decisamente ricchi e complessi, sia dal punto di vista tecnoscientifico e medico sia da quello filosofico – e lo fanno in un modo che ci permette di vedere questi quesiti sotto (...) una nuova luce. Il numero raccoglie alcune voci italiane, tedesche, inglesi e statunitensi su diversi aspetti della problematica dell’enhancement umano. Tra le tematiche discusse troviamo il potenziamento genetico, le dimensioni etiche dell’enhancement, la relazione uomo-tecnologia, il cosiddetto enhancement morale, la relazione tra enhancement ed eugenetica, la distinzione tra potenziamento e terapia e la rilevanza delle neuroscienze per lo sviluppo futuro delle bio-tecnologie, della medicina e dell’etica.

Este estudo pretende compreender a emblemática expressão «cultura do encontro», no marco do magistério e testemunho do Papa Francisco. Desde o início de seu pontificado, a categoria «encontro» recebe destaque em seus pronunciamentos e, principalmente, nos seus gestos. Em diversos momentos da história de Israel, as palavras e os gestos foram a forma escolhida por Deus para se revelar ao seu povo, especialmente por intermédio dos profetas. Pretende-se assim, também considerar a dimensão profética de seus ensinamentos e testemunho e, dessa (...) forma constatar como a cultura do encontro é uma atualização e epifania do Reino de Deus para os nossos dias. A abordagem consistirá em analisar como Francisco explica, descreve e propõe a cultura do encontro em seus pronunciamentos para identificar seu dinamismo. E, por fim, verificar como o próprio pontífice se exercita e promove a «cultura do encontro» mediante a consideração de suas 27 viagens apostólicas fora da Itália. (shrink)

Peter van Inwagen and Colin McGinn hold that there are strong arguments for strict incompatibilism, i.e. for the claim that the free will thesis (F) is inconsistent not just with determinism but with the negation of determinism as well. Interestingly, both authors deny that these arguments are apt to justify the claim that (F) is false. I argue that van Inwagen and McGinn are right in taking the fact that epistemic commitment to (F) is deeply rooted in common sense to (...) cast doubt on arguments to the conclusion that (F) is false. However, instead of declaring free will to be a mystery (van Inwagen) or claiming that the problem of free will amounts to a problem whose correct solution is cognitively closed to human intellect (McGinn), I propose to simply view the problem of free will as a hard problem – its hardness being due to the fact that it involves a large variety of concepts whose correct explication is philosophically moot.
