The analysis of critical incidents in the pre-professional practice of teacher training is essential to promote reflection. Building upon this notion, the urgent need for a reflective practice in the training of science teachers is addressed. In this context, future educators are instructed in the preparation of reports that highlight the critical incidents experienced in their pedagogical work. From these perspectives, reflective practice emerges as a fundamental resource to solidify their identity and pedagogical mastery by incorporating experiences for guidance purposes, (...) emphasizing the significance of reflection.

Long noncoding RNAs have been described in cell lines and various whole tissues, but lncRNA analysis of development in vivo is limited. Here, we comprehensively analyze lncRNA expression for the adult mouse subventricular zone neural stem cell lineage. We utilize complementary genome-wide techniques including RNA-seq, RNA CaptureSeq, and ChIP-seq to associate specific lncRNAs with neural cell types, developmental processes, and human disease states. By integrating data from chromatin state maps, custom microarrays, and FACS purification of the subventricular zone lineage, we (...) stringently identify lncRNAs with potential roles in adult neurogenesis. shRNA-mediated knockdown of two such lncRNAs, Six3os and Dlx1as, indicate roles for lncRNAs in the glial-neuronal lineage specification of multipotent adult stem cells. Our data and workflow thus provide a uniquely coherent in vivo lncRNA analysis and form the foundation of a user-friendly online resource for the study of lncRNAs in development and disease. © 2013 Elsevier Inc.

Background: This research explores how public awareness and attitudes toward donation and transplantation policies may contribute to Spain's success in cadaveric organ donation. Materials and Methods: A representative sample of 813 people residing in Andalusia (Southern Spain) were surveyed by telephone or via Internet between October and December 2018. Results: Most participants trust Spain's donation and transplantation system (93%) and wish to donate their organs after death (76%). Among donors, a majority have expressed their consent (59%), and few nondonors have (...) expressed their refusal (14%). Only a minority are aware of the presumed consent system in force (28%) and feel sufficiently informed regarding the requirements needed to be an organ donor (16%). Participants mainly consider that relatives should represent the deceased's preferences and be consulted when the deceased's wishes are unknown, as is the case in Spain. Conclusion: Public trust in the transplant system may contribute to Spain's high performance in organ donation. High levels of societal support toward organ donation and transplantation do not correspond with similar levels of public awareness of donation and transplantation policies in Spain. (shrink)

La obra de Charles Darwin trasciende los dominios de las ciencias biológicas. En el presente ensayo se valoran los impactos de su propuesta teórica �especialmente su incorporación de la historia en la teoría� en las revoluciones científicas, en la sociedad de su tiempo y la contemporánea. Se esbozan tres rasgos de sus aportaciones como científico profesional: la incorporación de la ética y la responsabilidad social, el vínculo con el pensamiento ambientalista contemporáneo y su comprensión del método científico.

Justo antes de la pandemia por COVID-19, la Organización Mundial de la Salud definió unas prioridades de trabajo para la década 2020-2030. Un grupo interdisciplinario de profesionales de la salud reflexiona sobre estas prioridades, determinando unas categorías de análisis y, desde una perspectiva bioética, analiza cada una de ellas, ve su pertinencia, algunos eventos causales, las implicaciones que pueden tener si no son enfrentadas adecuadamente y hace sugerencias sobre la forma de llevarlas a cabo. En esta primera entrega se analiza (...) el primer grupo de prioridades estratégicas: “poblaciones más sanas”. En las conclusiones se destaca la conveniencia de acometer cada una de ellas de una manera colaborativa, gubernamental y privada; de reestructurar el sector salud con base en estas prioridades, aprovechando la experiencia obtenida en la lucha contra el COVID-19. La relación del ser humano con el medio ambiente también debe cambiar, apelando a la responsabilidad humana por el cuidado del planeta. (shrink)

El objetivo de este trabajo es analizar los ejemplos que se dan en las obras tradicionales del denominado καί estructural con el fin de determinar sus características desde una perspectiva más actual. Este es uno de los tipos de καί adverbial que se distinguen, pero, como veremos, se trata de una categoría compleja en la que, sobre la base de su aparición en una oración subordinada, se han mezclado al menos tres usos más o menos habituales de καί adverbial: aditivo, (...) identificativo y corresponsivo. The aim of this paper is to analyse the examples of the so-called structural καί from a modern perspective. The examples are taken from the traditional grammars, in which this adverbial use of καί is usually distinguished. As it will be shown, this is in fact a complex category, established on the basis of its appearance in a subordinate clause and including three quite common uses of adverbial καί: additive, identificational and corresponsive.

A widespread need to explain the behavior and outcomes of AI-based systems has emerged, due to their ubiquitous presence. Thus, providing renewed momentum to the relatively new research area of eXplainable AI (XAI). Nowadays, the importance of XAI lies in the fact that the increasing control transference to this kind of system for decision making -or, at least, its use for assisting executive stakeholders- already affects many sensitive realms (as in Politics, Social Sciences, or Law). The decision-making power handover to (...) opaque AI systems makes mandatory explaining those, primarily in application scenarios where the stakeholders are unaware of both the high technology applied and the basic principles governing the technological solutions. The issue should not be reduced to a merely technical problem; the explainer would be compelled to transmit richer knowledge about the system (including its role within the informational ecosystem where he/she works). To achieve such an aim, the explainer could exploit, if necessary, practices from other scientific and humanistic areas. The first aim of the paper is to emphasize and justify the need for a multidisciplinary approach that is beneficiated from part of the scientific and philosophical corpus on Explaining, underscoring the particular nuances of the issue within the field of Data Science. The second objective is to develop some arguments justifying the authors’ bet by a more relevant role of ideas inspired by, on the one hand, formal techniques from Knowledge Representation and Reasoning, and on the other hand, the modeling of human reasoning when facing the explanation. This way, explaining modeling practices would seek a sound balance between the pure technical justification and the explainer-explainee agreement. (shrink)

This paper focuses on the consolidation of Molecular Evolution, a field originating in the 1960s at the interface of molecular biology, biochemistry, evolutionary biology, biophysics and studies on the origin of life and exobiology. The claim is made that Molecular Evolution became a discipline by integrating different sorts of scientific traditions: experimental, theoretical and comparative. The author critically incorporates Timothy Lenoir’s treatment of disciplines , as well as ideas developed by Stephen Toulmin on the same subject. On their account disciplines (...) are spaces where the social and epistemic dimensions of science are deeply and complexly interwoven. However, a more detailed account of discipline formation and the dynamics of an emerging disciplinary field is lacking in their analysis. The present essay suggests focusing on the role of scientific concepts in the double configuration of disciplines: the social/political and the epistemic order. In the case of Molecular Evolution the concepts of molecular clock and informational molecules played a central role, both in differentiating molecular from classical evolutionists, and in promoting communication between the different sorts of traditions integrated in Molecular Evolution. The paper finishes with a reflection on the historicity of disciplines, and the historicity of our concepts of disciplines. (shrink)

A main selling point of predicativism is that, in addition to accounting for predicative uses of proper names, it can successfully account for their referential uses while treating them as predicates, thus providing a uniform semantics for proper names. The strategy is to postulate an unpronounced determiner that is realised with names when they appear to function as singular terms, making them effectively a concealed determiner phrase. I argue against the thesis that names are really predicates in referential uses. I (...) discuss four different environments where names do not behave like the determiner phrases that are thought to embed them. (shrink)

El presente artículo tiene como objeto llevar a cabo un estudio pragmático y analítico sobre la acción de valoración, el valor y los valores a la luz de la ciencia semiótica y de la ciencia cibernética. Por ello, se desarrollará un proceso axiológico que ilustre cómo sucede el ingreso, la transición y la salida de códigos morales en función de un esquema cognitivo. Así pues, el proceso axiológico se postula, primero, en fundamento de tres sistemas: de mentalidad, de valores y (...) de biomoralidad y, segundo, conforme a la teoría de la información y de la teoría general de sistemas.

The use of molecules and reactions as evidence, markers and/or traits for evolutionary processes has a history more than a century long. Molecules have been used in studies of intra-specific variation and studies of similarity among species that do not necessarily result in the analysis of phylogenetic relations. Promoters of the use of molecular data have sustained the need for quantification as the main argument to make use of them. Moreover, quantification has allowed intensive statistical analysis, as a condition and (...) a product of increasing automation. All of these analyses are subject to the methodological anxiety characteristic of a community in search of objectivity. It is in this context that scientists compared and evaluated protein and nucleic acid sequence data with other types of molecular data – including immunological, electrophoretic and hybridization data. This paper argues that by looking at long-term historical processes, such as the use of molecular evidence in evolutionary biology, we gain valuable insights into the history of science. In that sense, it accompanies a growing concern among historians for big-pictures of science that incorporate the fruitful historical research on local cases of the last decades. (shrink)

This paper extends previous arguments against the assumption that the study of variation at the molecular level was instigated with a view to solving an internal conflict between the balance and classical schools of population genetics. It does so by focusing on the intersection of basic research in protein chemistry and the molecular approach to disease with the enactment of global health campaigns during the Cold War period. The paper connects advances in research on protein structure and function as reflected (...) in Christian Anfinsen’s The molecular basis of evolution, with a political reading of Emilé Zuckerkandl and Linus Pauling’s identification of molecular disease and evolution. Beyond atomic fallout, these advances constituted a rationale for the promotion of genetic surveys of human populations in the Third World, in connection with international health programs. Light is shed not only on the experimental roots of the molecular challenge but on the broader geopolitical context where the rising role of biomedicine and public health had an impact on evolutionary biology.

ArgumentThis paper explores the connection between the epistemic and the “political” dimensions of the metaphor of information during the early days of the study of Molecular Evolution. While preserving some of the meanings already documented in the history of molecular biology, the metaphor acquired a new, powerful use as a substitute for “history.” A rhetorical analysis of Emilé Zuckerkandl's paper, “Molecules as Documents of Evolutionary History,” highlights the ways in which epistemic claims on the validity and superiority of molecular evidence (...) for evolution were intimately connected with authority issues in evolutionary biology. The debate is situated within the framework of the battle for resources between traditional evolutionists and molecular biologists at the beginning of the 1960s. The architects of evolutionary synthesis questioned the idea that molecular characters constitute “cleaner” and “more direct” evidence of evolution. Nevertheless, the information discourse constituted a productive space for the development of a new research program that, paradoxically, has made explicit the limitations of the information metaphor in reconstructing life's history.

In this special issue we explore practices of scientific inquiry into human populations in Latin America in order to generate new insights into the complex historical and sociopolitical dynamics that have made certain human groups integral to the production of scientific knowledge in and about the region. In important contributions, other scholars have shown that the science of human difference is racist and all too often has been a mediator of development ideologies. To further unpack these arguments we focus attention (...) on the complex interaction between scientists and the populations they study. We explore cases from across the fields of evolutionary biology, demography, epidemiology... (shrink)

Las nociones de vida y biología adquieren distintos sentidos en la teoría de las generaciones o se expresan en distintas oposiciones según se sitúen en el campo político, filosófico o científico. Este artículo afronta estas dimensiones prestando especial atención al peculiar estilo de Ortega, en particular a las reiteradas metáforas biologicistas, asumiendo que son inseparables del contenido teórico presente en sus obras. Este estilo puede ser un instrumento muy apropiado para articular la relación de los campos entre sí y con (...) la biografía de Ortega, teniendo en cuenta su heterodoxa apuesta filosófica. (shrink)

BackgroundUmbilical cord banks are a central component, as umbilical cord tissue providers, in both medical treatment and scientific research with stem cells. But, whereas the creation of umbilical cord banks is seen as successful practice, it is perceived as a risky style of play by others. This article examines and discusses the ethical, medical and legal considerations that arise from the operation of umbilical cord banks in Mexico.DiscussionA number of experts have stated that the use of umbilical cord goes beyond (...) the mere utilization of human tissues for the purpose of treatment. This tissue is also used in research studies: genetic studies, studies to evaluate the effectiveness of new antibiotics, studies to identify new proteins, etc. Meanwhile, others claim that the law and other norms for the functioning of cord banks are not consistent and are poorly defined. Some of these critics point out that the confidentiality of donor information is handled differently in different places. The fact that private cord banks offer their services as "biological insurance" in order to obtain informed consent by promising the parents that the tissue that will be stored insures the health of their child in the future raises the issue of whether the consent is freely given or given under coercion. Another consideration that must be made in relation to privately owned cord banks has to do with the ownership of the stored umbilical cord.SummaryConflicts between moral principles and economic interests (non-moral principles) cause dilemmas in the clinical practice of umbilical cord blood storage and use especially in privately owned banks. This article presents a reflection and some of the guidelines that must be followed by umbilical cord banks in order to deal with these conflicts. This reflection is based on the fundamental notions of ethics and public health and seeks to be a contribution towards the improvement of umbilical cord banks' performance. (shrink)

A recent quarrel over faultless disagreements assumes that disputes over evaluative sentences should be understood as regular, factual disagreements. Instead, I propose that evaluative disagreements should be understood in Lewisian terms. Language use works like a rule-governed game. In it, the assertion of an evaluative sentence is an attempt to establish one value as default in the conversation; its rejection, in turn, is in most cases the refusal to accept this move.

Este trabajo retoma las categorías que trabaja Kant en función de la emisión de juicios con respecto al gusto y la estética. Para ello, es necesario que se considere el método que se configura a partir de la sistematización de las cosas y los fenómenos que intervienen para obtener su constitución. Asimismo, todo ello está orientado a precisar el concepto de estética, para que después se comprendan los tipos de juicios que se derivan de las facultades cognitivas, como los juicios (...) analíticos y sintéticos, los juicios a priori y a posteriori, los juicios determinantes y reflexionantes, los juicios estéticos en el Arte y los juicios teleológicos.

Adults (more than 18 years old) are likely to reproduce the habits that they acquired during childhood and adolescence (from 6 to 16 years old). For that reason, teachers and parents have the responsibility to promote an active and healthy lifestyle in children and adolescents. Even though every school subject should promote healthy activities, Physical Education (PE) is the most important subject to foster well-being habits associated to healthy lifestyle during sport practice and other kinds of active tasks. Indeed, there (...) are many factors that influence the acquisition of healthy habits that should be taken into account when programs and activities are implemented in both educational and extracurricular context. In this sense, psychological and social factors are of utmost importance to achieve optimal experiences for an active and healthy lifestyle. However, due to the myriad of studies analyzing different factors in different contexts, there could be confusion when programs and pedagogical strategies are applied in educational or extracurricular contexts. The objective of this investigation is to analyze the state of art of the psychosocial factors which influence the engagement in physical activities and sport practice. The keywords used in this review were mainly: ‘Self-Determination Theory’, ‘motivation’, ‘Psychological need satisfaction, ‘physical activity and sport engagement’, ‘Elementary Education’, ‘Secondary Education’, ‘Physical Education’. The articles were selected according to the following criteria: (a) peer-reviewed original research published in international journals indexed in JCR or SJR, (b) published in English or Spanish, (c) about psychosocial factors which influence the physical activity and sport engagement, (b) in educational or extracurricular context. Research articles selected were found through nine databases. It was observed that physical activities and sport practice engagement are closely related to psychological factors. In particularly, intrinsic motivation was able to determine the active participation in any activity, including physical activity and sport practice during the implementation of Small-Sided Games and other kinds of pedagogical strategies (e.g., Pedagogical Models). Motivation was also closely related to flow state. Finally, these variables should be considered in order to organize effective programs to promote an active and healthy lifestyle in Physical Education classes. (shrink)
