BACKGROUND: Reasoning biases have been suggested as risk factors for delusional ideation in both patients and non-clinical individuals. Still, it is unclear how these biases are longitudinally related to delusions in the general population. We hence aimed to investigate longitudinal associations between reasoning biases and delusional ideation in the general population. METHODS: We conducted an online cohort study with 1184 adults from the German and Swiss general population. Participants completed measures on reasoning biases (jumping-to-conclusion bias JTC, liberal acceptance bias LA, (...) bias against disconfirmatory evidence BADE, possibility of being mistaken PM) and delusional ideation at baseline, and delusional ideation 7 to 8 months later. RESULTS: A greater JTC bias was associated with a greater increase in delusional ideation over the following months. This association was better described by a positive quadratic relationship. Neither BADE, LA nor PM were associated with subsequent changes in delusional ideation. CONCLUSIONS: This study suggests that jumping-to-conclusions predicts delusional ideation in the general population but that this association may follow a quadratic trajectory. While no other associations turned significant, future studies with shorter temporal distances may shed further light on the role of reasoning biases as risk factors for delusional ideation in non-clinical samples.

This book contains the text of Thomas Kuhn's unfinished book, The Plurality of Worlds: An Evolutionary Theory of Scientific Development, which Kuhn himself described as "a return to the central claims of The Structure of Scientific Revolutions, and the problems that it raised but did not resolve." The Plurality of Worlds is preceded by two related texts that Kuhn publicly delivered but never published in English: his paper "Scientific Knowledge as a Historical Product" and his Shearman Memorial Lectures, "The Presence (...) of Past Science." The book opens with an introduction by the editor that describes the origins and structure of The Plurality of Worlds, and sheds light on its central philosophical problems. Kuhn's aims in his last writings are bold. He sets out to develop an empirically grounded theory of meaning that would allow him to make sense of both the possibility of historical understanding and the inevitability of incommensurability between past and present science. Moreover, he intends to show that incommensurability is fully compatible with a robust notion of a real world that science investigates, with the rationality of scientific belief change, and with the idea that scientific development is progressive. This is a must-read follow-up to The Structure of Scientific Revolutions, one of the most important books of the twentieth century. (shrink)

A highly condensed account of the author's present view of some philosophical problems unresolved in The Structure of Scientific Revolutions. The concept of incommensurability, now considerably developed, remains at center stage, but the evolutionary metaphor, introduced in the final pages of the book, now also plays a principal role.

The author's concept of incommensurability is explicated by elaborating the claim that some terms essential to the formulation of older theories defy translation into the language of more recent ones. Defense of this claim rests on the distinction between interpreting a theory in a later language and translating the theory into it. The former is both possible and essential, the latter neither. The interpretation/translation distinction is then applied to Kitcher's critique of incommensurability and Quine's conception of a translation manual, both (...) of which take reference-preservation as the sole semantic criterion of translational adequacy. The paper concludes by enquiring about the additional criteria a successful translation must satisfy. (shrink)

A good book may have the power to change the way we see the world, but a great book actually becomes part of our daily consciousness, pervading our thinking to the point that we take it for granted, and we forget how provocative and challenging its ideas once were—and still are. _The Structure of Scientific Revolutions _is that kind of book. When it was first published in 1962, it was a landmark event in the history and philosophy of science. Fifty (...) years later, it still has many lessons to teach. With _The Structure of Scientific Revolutions, _Kuhn challenged long-standing linear notions of scientific progress, arguing that transformative ideas don’t arise from the day-to-day, gradual process of experimentation and data accumulation but that the revolutions in science, those breakthrough moments that disrupt accepted thinking and offer unanticipated ideas, occur outside of “normal science,” as he called it. Though Kuhn was writing when physics ruled the sciences, his ideas on how scientific revolutions bring order to the anomalies that amass over time in research experiments are still instructive in our biotech age. This new edition of Kuhn’s essential work in the history of science includes an insightful introduction by Ian Hacking, which clarifies terms popularized by Kuhn, including paradigm and incommensurability, and applies Kuhn’s ideas to the science of today. Usefully keyed to the separate sections of the book, Hacking’s introduction provides important background information as well as a contemporary context. Newly designed, with an expanded index, this edition will be eagerly welcomed by the next generation of readers seeking to understand the history of our perspectives on science. (shrink)

Divided into three parts, this work is a record of the direction Kuhn was taking during the last two decades of his life. It consists of essays in which he refines the basic concepts set forth in "Structure"--Paradigm shifts, incommensurability, and the nature of scientific progress.

Post-translational histone modifications and their biological effects have been described as a ‘histone code’. Independently, Barbieri used the term ‘organic code’ to describe biological codes in addition to the genetic code. He also provided the defining criteria for an organic code, but to date the histone code has not been tested against these criteria. This paper therefore investigates whether the histone code is a bona fide organic code. After introducing the use of the term ‘code’ in biology, the criteria a (...) putative organic code such as the histone code must conform to in order to be recognised as an organic code are described. Our current knowledge of histones and their major post-translational modifications, and the specific protein binding domains that recognise and translate these into specific biological effects, is then reviewed in detail. The histone modification system is then placed in the context of an organic code and it is concluded that it fulfils all the requirements of an organic code. The marks produced on histones by processes such as acetylation and methylation act as organic signs that are translated into unique biological effects, their biological meanings. These translations are accomplished by effector proteins that consist of a binding domain that recognises a specific histone mark and a regulatory domain that mediates the biological effect. Crucially, these domains can be experimentally interchanged between different effector proteins, thus altering the rules that specify the relationships between sign and meaning. The effector proteins therefore fulfil the role of adaptor molecules. (shrink)

On this occasion, and in this place, I feel that I ought, and am probably expected, to look back at the things which have happened to the philosophy of science since I first began to take an interest in it over half a century ago. But I am both too much an outsider and too much a protagonist to undertake that assignment. Rather than attempt to situate the present state of philosophy of science with respect to its past — a (...) subject on which I’ve little authority — I shall try to situate my present state in philosophy of science with respect to its own past — a subject on which, however imperfect, I’m probably the best authority there is.As a number of you know, I’m at work on a book, and what I mean to attempt here is an exceedingly brief and dogmatic sketch of its main themes. I think of my project as a return, now underway for a decade, to the philosophical problems left over from the Structure of Scientific Revolutions. (shrink)

Corporate social responsibility in developing countries has recently received increasing attention, and scholars have pointed to the strong contextuality of CSR in the respective regions. Regarding the latter, however, sub-Saharan Africa has been scrutinized only marginally by academia. Moreover, empirical research on the impact of the institutional context has been scant, despite its attributed importance for CSR. Our article seeks to fill a part of this research gap by investigating CSR website reporting of 211 companies in seven sub-Saharan countries. The (...) study’s aim is twofold: First, we identify to what extent sub-Saharan companies report on CSR and which contents they disclose. Second, by building on institutional theory, we investigate how the socio-economic and political environments influence CSR reporting. For this purpose, we examine the impact of country-level and company-level determinants. We find that the sample African companies’ CSR efforts focus strongly on local philanthropy and therefore differ substantially from Western CSR approaches. Furthermore, we evidence that GDP and level of governance standard positively affect CSR reporting. Our study contributes to the literature by empirically evidencing the contextuality of CSR in Africa and by explaining how specific country- and company-level determinants contribute to or hamper the development of CSR in developing countries.

Thomas S. Kuhn acuno la expresion tension esencial para aludir al conflicto entre las tendencias conservadora y revolucionaria en la ciencia. Estas dan lugar respectivamente a la ciencia normal, que trata de salvar al paradigma dominante de las refutaciones, y a la extraordinaria, que responde a las dificultades sustituyendo las viejas teorias por otras radicalmente novedosas. La actitud adoptada en cada momento no esta dictada por normas de racionalidad, sino por la psicologia y la sociologia de los cientificos y sus (...) comunidades. Al conceder una funcion central a la psicosociologia en la explicacion del desarrollo cientifico, Kuhn creo la alta tension hoy omnipresente entre racionalidad e irracionalidad, objetividad y subjetividad, universalismo y relativismo, realismo e idealismo. Este homenaje a la obra de Kuhn recoge diversas contribuciones a las principales caras de esta tension, desde la perspectiva de la filosofia, la sociologia, la psicologia y la historia de la ciencia.

Researchers seeking to engage in projects related to Tribal communities and their citizens, lands, and non-human relatives are responsible for understanding and abiding by each Tribal nation’s research laws and review processes. Few studies, however, have described the many diverse forms of Tribal research review systems across the United States (US). This study provides one of the most comprehensive examinations of research review processes administered by Tribal Research Review Boards (TRRBs) in the US. Through a systematic analysis, we consider TRRBs’ (...) online presence, online documentation, and themes across documents, for five entity types: Tribal nations and Tribal consortiums, Tribal colleges and universities, Tribal health organizations, Indian Health Services, and other Tribal organizations. Results include an assessment of online presence for 98 potential TRRBs, identification of 118 publicly available online documents, and analysis of 41 themes across four document types: Tribal research codes and TRRBs’ guidelines, applications, and post-approval documents. Altogether, this research provides a macro-level analysis of the most common types of TRRBs in the US in an effort to increase researchers’ understanding of these important processes as they prepare to ethically engage Tribal communities in research. These results aim to empower Tribal decision makers as they align their TRRBs’ online visibility and documentation with community priorities and strengthen their protections for the rights and wellbeing of their citizens and community. Ultimately, by expanding our knowledge of TRRBs across the US, this contribution seeks to uphold Tribal sovereignty in research and promote ethical approaches to research with Indigenous communities.
