BackgroundPreprint usage is growing rapidly in the life sciences; however, questions remain on the relative quality of preprints when compared to published articles. An objective dimension of quality that is readily measurable is completeness of reporting, as transparency can improve the reader’s ability to independently interpret data and reproduce findings.MethodsIn this observational study, we initially compared independent samples of articles published in bioRxiv and in PubMed-indexed journals in 2016 using a quality of reporting questionnaire. After that, we performed paired comparisons (...) between preprints from bioRxiv to their own peer-reviewed versions in journals.ResultsPeer-reviewed articles had, on average, higher quality of reporting than preprints, although the difference was small, with absolute differences of 5.0% [95% CI 1.4, 8.6] and 4.7% [95% CI 2.4, 7.0] of reported items in the independent samples and paired sample comparison, respectively. There were larger differences favoring peer-reviewed articles in subjective ratings of how clearly titles and abstracts presented the main findings and how easy it was to locate relevant reporting information. Changes in reporting from preprints to peer-reviewed versions did not correlate with the impact factor of the publication venue or with the time lag from bioRxiv to journal publication.ConclusionsOur results suggest that, on average, publication in a peer-reviewed journal is associated with improvement in quality of reporting. They also show that quality of reporting in preprints in the life sciences is within a similar range as that of peer-reviewed articles, albeit slightly lower on average, supporting the idea that preprints should be considered valid scientific contributions.

Evidence is accumulating that individual and environmental factors in childhood and adolescence should be considered when investigating adult health and aging-related processes. The data required for this is gathered by comprehensive long-term longitudinal studies. This article describes the protocol of the Zurich Longitudinal Studies, a set of three comprehensive cohort studies on child growth, health, and development that are currently expanding into adulthood. Between 1954 and 1961, 445 healthy infants were enrolled in the first ZLS cohort. Their physical, motor, cognitive, (...) and social development and their environment were assessed comprehensively across childhood, adolescence, and into young adulthood. In the 1970s, two further cohorts were added to the ZLS and assessed with largely matched study protocols: Between 1974 and 1979, the second ZLS cohort included 265 infants, and between 1970 and 2002, the third ZLS cohort included 327 children of participants of the first ZLS cohort. Since 2019, the participants of the three ZLS cohorts have been traced and invited to participate in a first wave of assessments in adulthood to investigate their current health and development. This article describes the ZLS study protocol and discusses opportunities, methodological and conceptual challenges, and limitations arising from a long-term longitudinal cohort recruited from a study about development in early life. In the future, the ZLS will provide data to investigate childhood antecedents of adult health outcomes and, ultimately, will help respond to the frequent call of scientists to shift the focus of aging research into the first decades of life and, thus, to take a lifespan perspective on aging.

The Operation Lava Jato, initiated in 2014 by the Ministry of Finance and carried out by the Brazilian Government Agency for Law Enforcement and Prosecution of Crimes, brought to light the unethical practices of several national contractors, despite their declared commitment to social responsibility and ethical management—a corporate conduct epitomized in the popular saying: “Do what I say; don’t do what I do”. In this chapter, we analyze such disconnection between discourse and practice vis-a-vis the literature on leadership and business (...) ethics, Brazilian culture and historical analyses of the Brazilian contractors industry. We examine the official discourse of a Brazilian contractor, as observed in documents retrieved from websites and statements to the press, and its practices, as depicted in the media and documented in testimonies already conducted by the federal courts and attached to the original case-files. Specifically, we aim to contribute to the reflection on management and ethics in Brazil by identifying and discussing the factors that seem to have promoted such disconnection, including aspects of national culture and the institutional environment, together with organizational culture and leadership.

This paper presents an intuitive explanation about why and how Rawlsian Theory of Justice (Rawls in A theory of justice, Harvard University Press, Harvard, 1971) provides the foundations to a solution for algorithmic bias. The contribution of the paper is to discuss and show why Rawlsian ideas in their original form (e.g. the veil of ignorance, original position, and allowing inequalities that serve the worst-off) are relevant to operationalize fairness for algorithmic decision making. The paper also explains how this leads (...) to a specific MinMaxfairness solution, which addresses the basic challenges of algorithmic justice. We combine substantive elements of Rawlsian perspective with an intuitive explanation in order to provide accessible and practical insights. The goal is to propose and motivate why and how the MinMaxfairness solution derived from Rawlsian principles overcomes some of the current challenges for algorithmic bias and highlight the benefits provided when compared to other approaches. The paper presents and discusses the solution by building a bridge between the qualitative theoretical aspects and the quantitative technical approach. (shrink)

Given research and public interest for conditions related to an extended lifespan, we addressed the questions of what matters and what matters most for subsequent survival past age 80. The data was drawn from the population-based and multidisciplinary Swedish OCTO Twin Study, in which a sample consisting of identical and same-sex fraternal twin pairs, followed from age 80 until death, provided detailed data on health, physical functioning, life style, personality, and sociodemographic conditions. Information concerning date of birth and death were (...) obtained from population census register. We estimated heritability using an ACE model and evaluated the role of multiple predictors for the mortality-related hazard rate using Cox regression. Our findings confirmed a low heritability of 12%. As expected, longer survival was associated with being a female, an apolipoprotein E e4 allele non-carrier, and a non-smoker. Several diseases were found to be associated with shorter survival as well as certain health conditions. Stronger grip and better lung function, as well as better vision, and better cognitive function was related to longer survival. Social embeddedness, better self-evaluated health, and life-satisfaction were also significantly associated with longer survival. After controlling for the impact of comorbidity, functional markers, and personality-related predictors, we found that sex, cerebrovascular diseases, compromised cognitive functioning, self-related health, and life-satisfaction remained as strong predictors. Cancer was only associated with the mortality hazard when accounting for other co-morbidities. The survival estimates were mostly in anticipated directions and contained effect sizes within the expected range. Noteworthy, we found that some of the so-called “soft-markers” remained strong predictors, despite a control for other factors. For example, self-evaluation of health and ratings of life-satisfaction provide additional and valuable information. (shrink)

Punning on names was common in Old Comedy. Aristophanes punned on the name of Lamachus, who died at Syracuse. In the same play he made the famous joke, ‘some went to Kamarina, others to Gela, and some to Katagela’—‘an invention of the poet's from the fact that the men's officers laughed at them’.

Synaptophysin (Syp) was the first synaptic vesicle (SV) protein to be cloned. Since its discovery in 1985, it has been used by us and by many laboratories around the world as an invaluable marker to study the distribution of synapses in the brain and to uncover the basic features of the life cycle of SVs. Although single gene ablation of Syp does not lead to an overt phenotype, a large body of experimental data both in vitro and in vivo indicate (...) that Syp (alone or in association with homologous proteins) is involved in multiple, important aspects of SV exo‐endocytosis, including regulation of SNARE assembly into the fusion core complex, formation of the fusion pore initiating neurotransmitter release, activation of SV endocytosis and SV biogenesis. In this article, we summarise the main results of the studies on Syp carried out by our and other laboratories, and explain why we believe that Syp plays a major role in SV trafficking.

This paper is the result of my participation in a discussion event of Problema. Anuario de filosofía y teoría del derecho entitled “The Construction of Precedent in Civil Law: Debates, Concepts and Challenges”. Several colleagues with a vast knowledge on the subject of judicial precedent participated in this seminar, which also delved into the widely debated aspects of judicial precedent focused on the case of Chile. The entire discussion aimed at proposing solutions, as well as shedding some light on some (...) of its important aspects.Starting from such transcendental concepts as, rationality and argumentative use, it is possible to find certain problems arising from the improper use of the above concepts, which in turn leads us to stare decisis, a term that if used incorrectly may result in an act against the internal independence of judges.

The purpose of this scoping review is to investigate the value of creative arts therapies in healthy older adults. This article aims to shed light on current knowledge concerning the effectiveness of art therapies for the prevention of common age-related conditions using the definition of art therapy provided by the American Art Therapy Association, as well as Cohen’s conceptual framework for the psychological conceptualization of the relationship between the arts and health in later life. The objective is to carefully capture (...) subthreshold situations of distress, which are often not taken into account and primarily involve psychological aspects that are crucial in the multidimensional perspective of healthy aging. Twelve articles were selected and examined following an initial electronic search on 3 databases. A thematic analysis of the results identified four major themes: improving cognitive performance and proprioception; enhancing self-identity and meaningful life; reducing feelings of loneliness and depressive symptoms; and the importance of socialization. All these aspects constitute the basis for preventing psychological distress and enhancing mental well-being for healthy aging. (shrink)

El presente trabajo es el resultado de mi participación en el evento de discusión de la revista Problema. Anuario de Filosofía y Teoría del Derecho, que llevó por nombre “La construcción del precedente en el Civil Law: debates, conceptos y desafíos”, en el cual participaron varios colegas con un amplio conocimiento en el tema del precedente judicial; de igual forma, ahonda en los temas de mayor debate dentro de lo referente al precedente judicial, enfocado al caso chileno. Todo ello, con (...) la finalidad de proponer algunas soluciones al respecto, así como dilucidar ciertos aspectos importantes dentro del precedente. Partiendo de conceptos tan trascendentes como la prescriptibilidad, la racionalidad y el uso argumentativo, se logra llegar a ciertas problemáticas provocadas por el mal uso de los conceptos previamente mencionados, que a su vez nos conduce al stare decisis, término que mal utilizado puede resultar en un acto contrario a la independencia interna de la cual gozan los jueces.

Model-theoretic 1-types overa given first-order theory T may be construed as natural metalogical miniatures of G. W. Leibniz' ``complete individual notions'', ``substances'' or ``substantial forms''. This analogy prompts this essay's modal semantics for an essentiallyundecidable first-order theory T, in which one quantifies over such ``substances'' in a boolean universe V(C), where C is the completion of the Lindenbaum-algebra of T.More precisely, one can define recursively a set-theoretic translate of formulae νNϕ of formulae ν of a normal modal theory Tm based (...) on T, such that the counterpart `ξi' of a the modal variable `xi' of L(Tm) in this translation-scheme ranges over elements of V(C) that are 1-types of T with value 1 (sometimes called `definite' C-valued 1-types of T).The article's basic completeness-result (2.13) then establishes that ϕvarphi; is a theorem of Tm iff [[νN(ϕ) is aconsequenceof νN(Tm) for each extension N of T which is a subtheory of the canonical generic theory (ultrafilter) u]] = 1 – or equivalently, that Tm is consistent iff[[there is anextension N of T such that N is a subtheory of the canonical generic theory u, and νN(ϕ) for all ϕ in Tm]] > 0.The proof of thiscompleteness-result also shows that an N which provides a countermodel for a modally unprovable ϕ – or equivalently, a closed set in the Stone space St(T) in the sense of V(C) – is intertranslatable with an `accessibility'-relation of a closely related Kripke-semantics whose `worlds' are generic extensions of an initial universe V via C.This interrelation providesa fairly precise rationale for the semantics' recourse to C-valued structures, and exhibits a sense in which the boolean-valued context is sharp.

Platelets have important hemostatic functions in repairing blood vessels upon tissue injury. Cytokines, growth factors, and metabolites stored in platelet α‐granules and dense granules are released upon platelet activation and clotting. Emerging evidence indicates that such platelet‐derived signaling factors are instrumental in guiding tissue regeneration. Here, we discuss the important roles of platelet‐secreted signaling factors in skeletal muscle regeneration. Chemokines secreted by platelets in the early phase after injury are needed to recruit neutrophils to injured muscles, and impeding this early (...) step of muscle regeneration exacerbates inflammation at later stages, compromises neo‐angiogenesis and the growth of newly formed myofibers, and reduces post‐injury muscle force production. Platelets also contribute to the recruitment of pro‐regenerative stromal cells from the adipose tissue, and the platelet releasate may also regulate the metabolism and proliferation of muscle satellite cells, which sustain myogenesis. Therefore, harnessing the signaling functions of platelets and the platelet secretome may provide new avenues for promoting skeletal muscle regeneration in health and disease. (shrink)

“There`s only beauty if there is an interlocutor. The beauty of the lagoon is always someone” (Mãe, 2017, p.40). Valter Hugo Mãe expresses our desire in the making of this paper to share our experience of meeting refugee children, as part of an ongoing research project dedicated to exploring the conditions in which they live in Baixada Fluminense, Rio de Janeiro, Brazil, and the influences they bring with them from their birth countries. In the process of conducting this research, we (...) were surprised by a group of children who belong to the Warao ethnic group, and who have been welcomed by the municipality of Nova Iguaçu, which is part of Baixada Fluminense. The Warao are indigenous peoples from the North of Venezuela and their name means “canoe,” given their close relationship with water. A group of displaced Warao children and their families arrived in Nova Iguaçu after having “camped” out in the surroundings of Novo Rio bus station for a few weeks, followed by a sojourn in a public shelter, where the differences between them and the existing members of the institution led to conflict. Through a religious institution’s initiative, the families then found shelter in a small farm in the city of Japeri. They stayed there for six months, but once again were threatened by the prospect of eviction, after which they were finally welcomed in the city of Nova Iguaçu. The families–five interconnected units–expressed the wish to remain together and a social service institution found them a closed school building, which was modified to accommodate the group. When the Covid pandemic struck, the research and study group GEPELID began following the daily routine of these children at the shelter school and at the Marambaia welfare center. In their meetings with the Warao, the researchers were struck by their references to the Buriti tree as the “tree of life,” and the depths of its implications for their identity. In exploring this concept, the research group’s experience of radical cultural difference revealed the extent to which research in the human sciences is always a meeting with the other, and the relation between researcher and subjects an occasion for dialogue.

Parmenides and Melissus employ different deductive styles for their different kinds of argumentation. The former’s poem flows in an interesting sequence of passages: contents foreword, methodological premises, krisis, conclusions and corollaries. The latter, however, organizes an extensive process of deduction to show the characteristics of what is. In both cases, the strength of their argument rests on their deductive form, on the syntactical level of their texts: the formal structure of their reasonings help to identify the features and logical intersections (...) of their thoughts. On the one hand, Parmenides uses modal reasoning, enforcing the employment of the principle of the excluded middle. On the other hand, Melissus radicalizes the use of modal reasoning and employs counterfactual statements in order to develop his doctrine of what is. Despite their differences, both deserve a place in the Stone Age of logic and theory of argumentation due to their common ambition to demonstrate what is. (shrink)

This highly multidisciplinary collection discusses an increasingly important topic among scholars in science and technology studies: objectivity in science. It features eleven essays on scientific objectivity from a variety of perspectives, including philosophy of science, history of science, and feminist philosophy. Topics addressed in the book include the nature and value of scientific objectivity, the history of objectivity, and objectivity in scientific journals and communities. Taken individually, the essays supply new methodological tools for theorizing what is valuable in the pursuit (...) of objective knowledge and for investigating its history. The essays offer many starting points, while suggesting new avenues of research. Taken collectively, the essays exemplify the very virtues of objectivity that they theorize—in reading them together, the reader can sense various anxieties about the dangerously subjective in our age and locate commonalities of concern as well as differences of approach. As a result, the volume offers an expansive vision of a research community seeking a communal understanding of its own methods and its own epistemic anxieties, struggling to enunciate the key problems of knowledge of our time and offer insight into how to overcome them. -/- (Contributors: Alex Csiszar, Scott Edgar, Peter Galison, Ian Hacking, Sandra Harding, Moira Howes, Paolo Savoia, Judy Segal, Joan Steigerwald, and Alison Wylie).

In recent years, Reichenbach's 1920 conception of the principles of coordination has attracted increased attention after Michael Friedman's attempt to revive Reichenbach's idea of a "relativized a priori". This paper follows the origin and development of this idea in the framework of Reichenbach's distinction between the axioms of coordination and the axioms of connection. It suggests a further differentiation among the coordinating axioms and accordingly proposes a different account of Reichenbach's "relativized a priori".

Italian Sounding—i. e., the Italian appearance of a product or service brand irrespective of its country of origin—represents a global market phenomenon affecting a wide range of economic sectors, particularly the agro-food sector. Although its economic impact has been repeatedly stressed from different points of view, systematic scientific knowledge regarding its social–psychological bases is lacking. Three studies carried out in three different countries address this literature gap. Different consumer groups are targeted regarding major product categories pre-selected categories, which are the (...) major Italian food goods within the specific country according to piloting. In each study, the main independent variable has been manipulated by presenting real product images, whose “Italianness” degree is effectively manipulated by the main study variable across three or four levels. Main hypotheses are tested via a survey with the specific product images administered to samples in Italy, China, and the USA. Across the three studies, results show that Made in Italy products, compared to the other ones, are advantaged in terms of the main dependent variables: reputation profile, general reputation, attitude, and willingness to pay. Moreover, Italian Sounding products are endowed with corresponding significant advantages when compared to the Generic Foreign by non-Italian samples. Results reveal the specific social–psychological profile of Italian Sounding products in terms of either weaknesses or strengths when compared to both Made in Italy products and Generic Foreign ones, differently in the eyes of Italian and non-Italian consumers across different countries. Finally, consistently across the three studies, the extent to which a food product is perceived to be Italian increases consumers' WTP for that product, and this effect is consistently mediated by the product's reputation.

Species are considered the basic unit of biological classification and evolution. Hence, they are used as a benchmark in several fields, although the ontological status of such a category has always been a matter of debate. This paper aims to discuss the problem of the definition of species within the new mechanistic approach. Nevertheless, the boundary between entities, activities, and mechanisms remains difficult to establish and always requires an analysis of what is meant by explanation. As a case study, the (...) paper describes the debate concerning the species category by considering different kingdoms: Animals, Bacteria, and Fungi. The inherently biological differences between those groups prevent the use of a single, universally applicable concept of species that could fit the mechanisms responsible for the variability present in these kingdoms. The same issue is encountered within each group, as highlighted through a focus on mammals and microbes. This controversy has given rise to opposite approaches, namely: monism, which looks for a single definition that might account for all species, and pluralism, which admits that different groups of organisms require somewhat different definitions. In order to develop an adequate definition of species, we propose to apply a new mechanistic framework, which considers the ontic-epistemic dimensions of scientific explanation in close parallel. The apt correlation between epistemic and the ontic aspects highlights the way in which the concept of species and the reference to data are strictly co-determined. This suggests that the concept of species is better understandable within a dual ontic-epistemic approach. (shrink)

Es conocido el efecto de espectacularización derivado del proceso de colonialización-mundialización de la cultura: una vez que la actividad local ingresa en la economía política mundial de la cultura, cada acontecimiento se vuelve espectáculo , con su doble aspecto de “estrellato” y “museificación”. En efecto, ante la multiplicación de modos de vida que circulan en las redes telecomunicacionales, Estados e industrias culturales buscan por un lado preservar formas sociales y culturales que se consideran en peligro y, por otro, difundir y (...) explicar esas mismas formas. En este marco, el museo ha aparecido últimamente como uno de los dispositivos privilegiados para afrontar este doble propósito.

Me refiero al Museo-Taller Ferrowhite, ubicado en Ingeniero White, provincia de Buenos Aires. Propongo que se trata de un museo que se sabe un artefacto cultural hiper complejo, capaz de identificar la tensión que él mismo encarna, como institución estatal, al intentar contar la (su) historia y proponer un sentido para el rescate de esa historia en el presente.

Spatial representations have been considered for their high didactical efficacy, as concept maps and mind maps. Graphical and spatial representations may be seen as key elements of knowledge management and may contribute to enhancing spatial knowledge. Even if isomorphisms between the physical and the mental dimension can be controversial in the field of spatial knowledge, it is nevertheless interesting to study the role of spatial interpretation in knowledge management processes. In science education, spatial skills are actually highly required due to (...) the development of new technologies and their highly demanding spatial tasks they often work intertwined with other abilities, such as logical reasoning and verbal skills. Despite spatial knowledge being significative in the overall field of learning management, there is instead little research that shows its complex role in the comprehension of concepts in the humanistic fields, e.g. in philosophical conceptual reasoning. The Elementary Logic Theory—which underlies the philosophical maps of this Atlas—identifies at the basis of complex thinking prototypical knowledge units that may be activated in the possible collaboration between explicit and implicit thinking. In EL Theory, spatiality is considered the most suitable transition format for the hypothesized collaboration between implicit and explicit processing because it shares common aspects with both of them. The focus of EL Theory is to research particularly the role of the implicit in knowledge comprehension through spatial representations. In this Atlas, the role of Elementary Logic Theory is highlighted in shaping philosophical knowledge and comprehension of philosophical concepts and their intertwining. (shrink)

In this article the author maintains that complexity theory relies on reductionist assumptions, showing itself not to be completely convincing in dealing with the issue of novelty. First, an outline of Mark C. Taylor's The Moment of Complexity is presented as an exemplary case, particularly for his attempt to import complexity theory into the social sciences. Then, the connection between complexity theory and evolutionism is considered, arguing that this connection prevents complexity theory from giving a convincing account of the emergence (...) of novelty. A provisional conclusion is offered by arguing that novelty should be conceived as arising from a "widening" of reduction at the individual level. (shrink)

May implicit and explicit collaboration influence text comprehension and spatial recognition interaction? Visuospatial representation implies implicit, visual and spatial processing of actions and concepts at different levels of awareness. Implicit learning is linked to unaware, nonverbal and prototypical processing, especially in the early stages of development when it is prevailing. Spatial processing is studied as knowledge prototypes , conceptual and mind maps . According to the hypothesis that text comprehension and spatial recognition connecting processes may also be implicit, this paper (...) analyzes the possibility to identify and to define implicit non verbal criteria for organizing concepts into spatial representation. The focus of the research question is if prototypical processing (mainly implicit, but also explicit) criteria of conceptual organization may be model based. According to Thinking Prototypes Theory , explicit knowledge could be supported by implicit models of basic processing. On implicit side, conceptual development could be the resultant of the increasing complexity of prototypical implicit models interaction during individual lifespan, as in conceptual change research explicit conceptual development may be dependent on correlation . Unlike Theory Theory in Thinking Prototypes Theory implicit processing may collaborate with explicit knowledge without transforming itself from implicit to explicit. Prototypical implicit processing is considered as an entanglement of basic functions operating synergically in a complex way. Prototypical implicit processing units may be classified as far as they concern different basic thinking operations ( add , chain , each , compare , focus and link ). The experimental design was developed with primary school students in Naples. (shrink)

In his Scientific Representation (2008), van Fraassen argues that measuring is a form of representation. In fact, every measurement pinpoints its target in accordance with specific operational rules within an already-constructed theoretical space, in which certain conceptual interconnections can be represented. Reichenbach’s 1920 account of coordination is particularly interesting in this connection. Even though recent reassessments of this account do not do full justice to some important elements lying behind it, they do have the merit of focusing on a different (...) aspect of his early work that traditional interpretations of relativized a priori principles have unfortunately neglected in favour of a more “structural” role for coordination. In Reichenbach’s early work, however, the idea of coordination was employed not only to indicate theory-specific fundamental principles such as the ones suggested in the literature on conventional principles in science, but also to refer to more “basic” assumptions. In Reichenbach, these principles are preconditions both of the individuation of physical magnitudes and of their measurement, and, as such, they are necessary to approach the world in the first instance. This paper aims to reassess Reichenbach’s approach to coordination and to the representation of physical quantities in light of recent literature on measurement and scientific representation. (shrink)
