The almost simultaneous and overlapping discoveries of Mendel's forgotten work by Hugo de Vries, Carl Correns, and Erik von Tschermak gave rise to an intense rivalry, some jealousy, and more than a little illfeeling. De Vries, the first to announce the discovery, has been subjected to the charge that he wished to conceal his discovery and to obtain for himself the credit for having discovered what we now call Mendelism. This charge involves the statement that de Vries gave credit (...) to Mendel only after he had found that others had also read Mendel's papers. The evidence on which this charge is based is sketchy, and we can now show that at least that portion of it that is based on supposed alteration in the proof of de Vries' paper in the Berichte is without foundation. Unfortunately, de Vries gave three different accounts of how he was led to Mendel's work. Two of these involve Liberty Hyde Bailey.Bailey had listed Mendel's papers in a bibliography that he published in 1892 in The Rural Library. Bailey did not include this bibliography in the first edition (1895) of Plant Breeding or in its reprinting in 1896 and 1897. He did include the bibliography in the second edition (1902), but this was after de Vries and others had called attention to Mendel. In 1899, both Bailey and de Vries gave papers at the Hybrid Conference held at Chiswick, England, but we have no record of their having discussed Mendel. What evidence we have indicates that, at this time, neither of them had read Mendel's papers.De Vries wrote to Bailey that it was Bailey's listing of Mendel in the bibliography published in The Rural Library that led to his discovery of Mendel. Later, de Vries wrote to H. F. Roberts that he had first found a reference to Mendel in Bailey's Plant Breeding of 1895, where the bibliographic reference to Mendel's papers was not published. Finally, de Vries told Th. J. Stomps, who succeeded him at the University of Amsterdam, that he had first learned of Mendel early in 1900 from a reprint of Mendel's paper sent him by his friend Professor M. W. Beyerinck. Our present evidence favors Stomp's account as it shows that de Vries had not read Mendel's papers in 1899 but had early in 1900.Attempts to pinpoint de Vries' discovery of Mendel are aided in part, and in part confused, by the fact that he published five relevant papers in 1900. These papers were in press simultaneously, and some of them were altered in proof. Further confusion is due to the fact that at least three of them were published in the reverse order of their acceptance for publication. Unfortunately we do not have the crucial dates for all of the papers.J. Roy. Hort. Soc. 24: 69–75. A definitely pre-Mendelian paper given on 11 July 1899, and published in 1900 (possibly in April). The evidence for an alteration in proof after de Vries had read Mendel is shown by the fact that de Vries described a ratio of 99 to 54 as a 3 to 1 ratio.Rev. gén. botan. 12: 129–137. A Mendelian paper, giving the 3 to 1 ratio in the F2 generation of a cross between starchy and sugary corn. The paper is not dated by de Vries but it was published in the volume, 128 pages ahead of a paper de Vries dated 19 March. In a footnote, de Vries cites a paper by Correns that was published on 25 January, so we can tell that it was written or corrected in proof after this date. Here Correns showed de Vries that he had already read Mendel's paper. Any attempt by de Vries to ignore Mendel or get credit for Mendelism after 25 January would have been senseless. This date was nearly two months before de Vries' Berichte paper was submitted for publication.Ber. deut. botan. Ges. 18: 83–90. Accepted for publication 14 march, published 25 April. This paper gives Mendel full credit and stimulated the publications of Correns and von Tschermak. As de Vries was aware that Correns already knew of Mendel when the paper was first submitted, there was no occasion to alter it in proof.Rev. gén. botan. 12: 257–271. Dated by de Vries 19 March, but the proof was read after June. De Vries cites von Tschermak's paper in the Berichte that was published in June. The Revue paper is a Mendelian paper, and Mendel is cited on the last page.C. R. Acad. Sci. (Paris) 130: 845–847. Accepted for publication 26 March 1900. Reprint received by Correns 21 April. Mendel is not mentioned but de Vries' use of terms told Correns that de Vries had read Mendel's paper. First of the papers to be published, it caused Correns to assume that de Vries wanted the credit that was due Mendel.The three discoverers of Mendel did not form a mutual admiration society.

This paper centers on a case study of CSR performativity during the COVID-19 pandemic. In the extant CSR literature, CSR performativity has focused on “walking the talk” and/or “talking the walk,” wherein narrative and action around CSR are typically treated as two different things with their relationships questioned. We focus on what has been called “t(w)alking” wherein speech is understood to be performative and wherein speech acts and CSR are merged, becoming one and the same thing. Performativity then entails what (...) is (and what is not) said, whereby CSR involves taking responsibility for speech and/or silences. Our thesis is that the COVID-19 pandemic led to the “presenting” of CSR as performativity, in the presence of Levinas' Other, as noble (speech) acts. We examine what became of CSR performativity in a for-profit medical services provider when the COVID-19 pandemic turned fatal for its main client group: the infirm elderly. The performativity of the statement: “The elderly and their carers must be protected” turned out to be crucial and set the stage for the provider's emergency action. Following on insights derived from Nietzsche and Levinas, and more specifically from their views on the particularity of ethical action, we find that CSR morphed into ethical performativity in the case study at hand. Against the backdrop of the views of these thinkers, the research potential of the performativity of “t(w)alking” in future CSR studies emerges and is critically discussed. (shrink)

Resumo: O presente artigo apresenta uma epítome da dissertação “Os pressupostos filosóficos e os imperativos fundamentais da teoria crítica incipiente de Herbert Marcuse: em torno dos ensaios da ZfS (1937-1941). (SALDANHA, 2020)”. Essa pesquisa buscou identificar os traços distintivos da teoria crítica que Marcuse esboça nos ensaios publicados na Zeitschrift für Sozialforschung entre 1937-1941, tendo acedido a duas conclusões gerais: 1) que essa teoria se baseia em dois pressupostos filosóficos maiores, a saber, a dialética hegeliana e a crítica de economia (...) política de Marx; 2) que os referidos ensaios sugerem quatro tópicos cuja crítica seria impreterível para uma teoria genuinamente crítica da sociedade capitalista. Buscarei reconstituir a análise textual que levou às conclusões acima, descrevendo o contexto histórico-filosófico dos ensaios, suas premissas filosóficas mais importantes e os seus quatro tópicos fundamentais de análise. Tais tópicos constituem uma espécie de espinha dorsal da teoria crítica marcuseana da época e nos fornecem uma adequada chave de leitura para os seus ensaios. Palavras-chave: Teoria Crítica; Trabalho Alienado; Capitalismo; Liberdade; Marcuse. A key to understand Marcuse’s essays (1937-1941) Abstract: This paper provides a synthesis of the research entitled Autor. This research sought to identify the distinctive features of critical theory that Marcuse outlines in his 1937-1941 essays, reaching two major conclusions: 1) Marcusean theory is based on two philosophical assumptions, namely, Hegelian dialectics and Marx's critique of political economy; 2) Marcuse’s essays suggest four topics whose critique is imperative for a genuinely critical theory of capitalist society. I will try to reconstruct the textual analysis that led to the aforementioned conclusions, by analyzing the essays’ historical-philosophical context, their chief philosophical premises, and their four fundamental topics. I argue these topics constitute a kind of backbone of Marcuse's critical theory, and they provide us with an adequate key to comprehend his 1937-1941 essays.

A presente resenha tem por objetivo descrever o livro "Infâncias Negras: vivências e lutas por uma vida justa", o qual celebra a resiliência, a criatividade, resistência e agência das crianças negras, mostrando como elas encontram formas de se afirmar, se fortalecer e se empoderar em meio às adversidades sociais e em seu contexto escolar.

O presente artigo objetiva, ao revisitar a obra Oratio de hominis dignitate composta pelo humanista renascentista Giovanni Pico Della Mirandola, um duplo intento: sustentar que as noções de dignidade e liberdade, presentes nessa obra, se distanciam do pensamento cristão tradicional, de modo crítico, justamente porque derivam de uma leitura filosófica da teologia cristã da criação; e mostrar que a conclusão a respeito da noção de liberdade apresentada por Sartre no pensamento contemporâneo pode ser encontrada de modo germinal, guardada as devidas (...) proporções, na leitura piquiana da criação. Para tanto, exporemos uma breve retomada do contexto histórico-filosófico que permitiu ao filósofo engendrar a Oratio bem como suas pretensões para com essa obra; falaremos, em um segundo momento, como o platonismo religioso de Marsílio Ficino, principal matriz teórica a partir do qual os conceitos de dignidade e de liberdade foram modulados, foi recebido e desenvolvido no pensamento de Pico; e como as influências e as rupturas com pensamento de Ficino e a leitura filosófica da teologia cristã da criação são importantes para recolocar os conceitos de dignidade e de liberdade, permitindo assim entrever, por meio deles, semelhanças com o pensamento satreano.

Este trabalho consistiu na análise do Projeto Político Pedagógico (PPP) de uma escola do município de Barro Preto (BA), realizada sob a ótica da abordagem sociointeracionista, no qual buscamos identificar indícios que pudessem evidenciar a preocupação com o desenvolvimento cognitivo do estudante, que segundo Vygotsky (1998), é construído, em parte, pelo processo de maturação do sujeito, mas, também, por meio das influências sociais. Foi realizada uma pesquisa documental e a análise demonstrou que a escola defende o sociointeracionismo de Vygotsky no (...) PPP como norteador pedagógico e considera os quatro pilares da educação destacando a relevância do ambiente social e das interações para o desenvolvimento cognitivo e da aprendizagem e a importância do professor nesse processo.

O presente artigo é uma discussão sobre a noção heideggeriana de Überwindung. Seu objetivo é duplo: por um lado, [1] mostrar a perspectiva que tal termo deve ser compreendido; por outro, [2] aprofundar esta perspectiva à luz de comentários ao aforismo I do texto Überwindung der Metaphysik. Para tanto, duas questões são postas: em que perspectiva e que questões estão implícitas quando Heidegger propõe o projeto da Überwindung der Metaphysik?; e por que uma Überwindung contém em si tantos problemas? De (...) modo a discutir e comentar tais questões, o artigo percorre dois caminhos: [1] faz-se uma análise da própria indicação heideggeriana da perspectiva de compreensão da Überwindung der Metaphysik, qual seja, revisitar, a partir de um olhar determinado, a construção da noção de história do ser. Esta, por sua vez, tem sua gênese antes mesmo da própria Kehre. Mais especificadamente, na reinterpretação que o próprio Heidegger faz de seu texto Vom Wesen der Wahrheit. A partir desta reconsideração feita por Heidegger e inserida em seu próprio texto, é possível detectar quatro teses fulcrais que traçam essencialmente a metafísica e que justificam a sua superação. São elas: [a] o fato de o ser, originariamente, se velar e provocar, historialmente, o seu esquecimento; [b] a relação entre a verdade do ser e a história, que se desenvolve como história do ser; [c] a ideia de que pertence ao ser um caráter originário de retração de si mesmo e que essa retração é um destino que pertence à história do pensamento metafísico e se configura na própria essência da metafísica; [d] afirmar que a certeza da manifestação da essência coincide com o seu fim. [2] Adentra-se, mediante uma aproximação pari passu, no aforismo I do texto Überwindung der Metaphysik, com intuito de comentar a problematicidade do termo Überwindung quando usado para repensar a metafísica à luz da perspectiva da história do ser.

In _Philosophy and the Idea of Freedom_ Roy Bhaskar sets out to develop a critique of the work of Richard Rorty, who must be one of the most influential authors of recent decades. In a brilliant tour de force, Bhaskar shows how Rorty falls victim to the very epistemological problematic Rorty himself describes. Roy Bhaskar argues that Rorty’s account of science and knowledge is based on a half-truth. He sees the historicity of knowledge, but cannot sustain its rationality or the (...) reality of the objects it describes. The author further argues that Rorty’s problem-field replicates the Kantian resolution of the third antinomy: we are determined as material bodies, but free as discursive subjects. Rorty’s actualism makes human agency impossible. Developing his own critical realism, Bhaskar shows just where Rorty’s system comes unstuck, and how the philosophical problems to which it gives rise can be rationally resolved and explained. In this process Bhaskar utilizes his critique of Rorty to begin to elaborate his own alternative interpretation and critique of the philosophical conversation of the West. (shrink)

The article provides a conceptualization of self(-illness) ambiguity and investigates to what extent self(-illness) ambiguity is ‘special’. First, we draw on empirical findings to argue that self-ambiguity is a ubiquitous phenomenon. We suggest that these findings are best explained by a multidimensional account, according to which selves consist of various dimensions that mutually affect each other. On such an account, any change to any particular self-aspect may change other self-aspects and thereby alter the overall structural pattern of self-aspects, potentially leading (...) to self-ambiguity. Second, we propose that self-ambiguity comes in degrees and should be understood as a spectrum (as opposed to there being qualitative differences among instances of self-ambiguity). Third, we argue that complexity is the most useful dimension to organize cases of self-ambiguity, with mundane instances of self-ambiguity on the one end and self-illness ambiguity on the other end of the spectrum. Fourth, we address the promises and perils of narrativity with regard to self-ambiguity. Finally, we link our deflationary account of self(-illness) ambiguity to pattern theories of self. (shrink)

The paper presents a dilemma for both epistemic and non-epistemic versions of conceivability-based accounts of modal knowledge. On the one horn, non-epistemic accounts do not elucidate the essentialist knowledge they would be committed to. On the other, epistemic accounts do not elucidate everyday life de re modal knowledge. In neither case, therefore, do conceivability accounts elucidate de re modal knowledge.

The article proposes a theoretical model to account for changes in self due to Deep Brain Stimulation. First, we argue that most existing models postulate a very narrow conception of self, and thus fail to capture the full range of potentially relevant DBS-induced changes. Second, building on previous work by Shaun Gallagher, we propose a modified ‘pattern-theory of self’, which provides a richer picture of the possible consequences of DBS treatment.

Background In neonatal intensive care, a child's death is often preceded by a medical decision. Nurses, social workers and pastors, however, are often excluded from ethical case deliberation. If multiprofessional ethical case deliberations do take place, participants may not always know how to perform to the fullest. Setting A level-IIID neonatal intensive care unit of a paediatric teaching hospital in the Netherlands. Methods Structured multiprofessional medical ethical decision-making (MEDM) was implemented to help overcome problems experienced. Important features were: all professionals (...) who are directly involved with the patient contribute to MEDM; a five-step procedure is used: exploration, agreement on the ethical dilemma/investigation of solutions, analysis of solutions, decision-making, planning actions; meetings are chaired by an impartial ethicist. A 15-item questionnaire to survey staff perceptions on this intervention just before and 8 months after implementation was developed. Results Before and after response rates were 91/105 (87%) and 85/113 (75%). Factor analysis on the questionnaire suggested a four-factor structure: participants' role; structure of MEDM; content of ethical deliberation; and documentation of decisions/conclusions. Effect sizes were 1.67 (p<0.001), 0.69 (p<0.001) and 0.40 (p<0.01) for the first three factors respectively, but only 0.07 (p=0.65) for the fourth factor. Nurses' perceptions of improvement did not significantly exceed those of physicians. Conclusion Professionals involved in ethical case deliberation perceived that the process of decision-making had improved; they were more positive about the structure of meetings, their own role and, to some extent, the content of ethical deliberation. Documentation of decisions/conclusions requires further improvement. (shrink)

This article is an attempt at understanding the use that Abhinavagupta, the Kashmiri Śaiva philosopher and scholar of poetics, makes of a few concepts and theories stemming from the tradition of Vedic ritual exegesis. Its starting point is the detailed analysis of a key passage in Abhinavagupta’s commentary on the “aphorism on rasa” of the Nāṭyaśāstra, where the learned commentator draws an analogy between the operation of the non-prescriptive portions of the Veda in the ritual and the “generalisation” taking place, (...) according to him, in the appreciation of a work of art. Arguing against the tendency of modern historiography to explain this analogy exclusively in terms of Kumārila’s theory of effectuation in its two modalities, the article endeavours to show how Abhinavagupta relies on a variety of other textual sources he knew extensively and presumably first-hand. Some of them belong to the great Mīmāṃsaka tradition ; others, to different trends of medieval Brahmanism claiming exegetical heritage, as in the case of Jayanta Bhaṭṭa’s Nyāyamañjarī The nature of Abhinavagupta’s debt to Bhaṭṭa Nāyaka and his concept of bhāvanā is also reconsidered in light of these new findings. This investigation finally leads to identify, in the Abhinavabhāratī, an original theory of scriptural narratives and their efficacy, irreducible to any of its exegetical sources. According to this theory, mythological passages of the Veda directly prompt action, through the same capacity of abstraction or “de-temporalisation” that is at work in our appraisal of literature and theatre.

Many studies claim to measure decision-making under risk by employing the Domain-Specific Risk-Taking (DOSPERT) scale, a self-report measure, or the Balloon Analogue Risk Task (BART), a behavioural task. However, these tasks do not measure decision-making under risk but decision-making under uncertainty, a related but distinct concept. The present commentary discusses both the theoretical and empirical basis of the distinction between uncertainty and risk from the viewpoint of several scientific disciplines and reports how many studies wrongfully employ the DOSPERT scale and (...) BART as risk-taking measures. Importantly, we call for proper distinguishing between (tasks measuring) decision-making under uncertainty and decision-making under risk in psychology and related fields. We believe this is vital as research has shown that people’s attitudes, behaviour, and brain activity differ between both concepts, indicating that confusing the concepts may lead researchers to erroneous conclusions.

A partir de uma leitura integrada dos diálogos Fédon e Banquete, pretendemos revisar a interpretação tradicional de Platão como um filósofo que despreza o corpo e os sentidos, demonstrando que a filosofia platônica entrelaça amor, sensopercepção e saber. No Fédon, destacamos a importância das sensopercepções para a anamnese. No Banquete, apresentamos Éros como um impulso inerente à constituição humana, cujo desejo pelas coisas belas é capaz de elevar os indivíduos à contemplação das formas inteligíveis. Através da abordagem desses diálogos, torna-se (...) claro que Platão não defende um ascetismo radical, mas reconhece o corpo e o desejo como elementos fundamentais para a atividade filosófica, estabelecendo que o amor e a sensibilidade são condições de possibilidade para o acesso ao verdadeiro saber.

The paper focuses on the Epistemic Challenge for mind-independent accounts of modality. The challenge can be formulated as an inconsistency problem among three premises and, therefore, any strategy to meet the challenge will require the negation of (at least) one of its premises. The aim of the paper is not to offer a positive solution to the challenge, but rather to argue for the claim that to follow a hybrid strategy is probably the best way to meet it. With some (...) qualifications, reasons are given as to why empiricism should be the way to meet the challenge as far as de re modality is concerned, whereas rationalism might be the correct way of addressing it for the case of de dicto modality.

We assessed how synchronous speech listening and lipreading affects speech recognition in acoustic noise. In simple audiovisual perceptual tasks, inverse effectiveness is often observed, which holds that the weaker the unimodal stimuli, or the poorer their signal-to-noise ratio, the stronger the audiovisual benefit. So far, however, inverse effectiveness has not been demonstrated for complex audiovisual speech stimuli. Here we assess whether this multisensory integration effect can also be observed for the recognizability of spoken words. To that end, we presented audiovisual (...) sentences to 18 native-Dutch normal-hearing participants, who had to identify the spoken words from a finite list. Speech-recognition performance was determined for auditory-only, visual-only (lipreading) and auditory-visual conditions. To modulate acoustic task difficulty, we systematically varied the auditory signal-to-noise ratio. In line with a commonly-observed multisensory enhancement on speech recognition, audiovisual words were more easily recognized than auditory-only words (recognition thresholds of -15 dB and -12 dB, respectively). We here show that the difficulty of recognizing a particular word, either acoustically or visually, determines the occurrence of inverse effectiveness in audiovisual word integration. Thus, words that are better heard or recognized through lipreading, benefit less from bimodal presentation. Audiovisual performance at the lowest acoustic signal-to-noise ratios (45%) fell below the visual recognition rates (60%), reflecting an actual deterioration of lipreading in the presence of excessive acoustic noise. This suggests that the brain may adopt a strategy in which attention has to be divided between listening and lipreading. (shrink)

We investigate what distinguishes social entrepreneurial ecosystems (SEEs) from entrepreneurial ecosystems (EEs) through appreciation of the importance of context—the multiplex of intertwined social, spatial, temporal, historical, cultural, and political influences. Community is incorporated as a key variable and hitherto overlooked dimension of the structure and influence of SEEs. We draw on extant literature and examples of a variety of SEEs to support our propositions and demonstrate why considerations of both context and community are critical to advance understanding of SEEs. We (...) contribute to the study of SEEs by presenting a new conceptual framework and theorizing SEE as an evolving composite of interdependent actors who interact and collaborate across multiple levels to collectively generate positive externalities and drive sustainable solutions to social problems.
