"Who knows how much longer it will be, but others have crossed over to the US, and have found a job, and have even sent for their families. I am not the only one crossing, I am number 57 out of 72, but we do not walk together, all 72—that would call too much attention to us. We walk at a good pace, each one with their thoughts, we walk from sun to sun without stopping almost; others have done it." (...)

RESUMEN: Abir-Am ha criticado la visión estándar de que la Fundación Rockefeller jugó un papel central en el surgimiento de la biología molecular durante la década de 1960. En su opinión, la FR aceleró la molecularización de las ciencias de la vida, pero no intervino de manera directa en el surgimiento de la biología molecular como disciplina. Aquí sostengo que esta crítica tiene consecuencias mayores a las que sospechó su autora y muestro que la tesis de la centralidad de la (...) FR en el desarrollo de la biología molecular no se puede desmantelar sin alterar también la visión de la biologia molecular como una disciplina orientada a la resolución de problemas predefinidos.ABSTRACT: Abir-Am has critiqued the standard view that the Rockefeller Foundation played a central role in the development of molecular biology during the 1960s. In her view, the RF accelerated the molecularization of the life sciences, but it did not directly contribute to building molecular biology’s disciplinary identity. Here I argue that Abir-Am’s critique has more consequences than she envisioned, and I show that the thesis of the centrality of the RF cannot be dismantled without also altering the view of molecular biology as a field oriented towards the solution of predefined problems.

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)

Although the interdisciplinary nature of contemporary biological sciences has been addressed by philosophers, historians, and sociologists of science, the different ways in which engineering concepts and methods have been applied in biology have been somewhat neglected. We examine - using the mechanistic philosophy of science as an analytic springboard - the transfer of network methods from engineering to biology through the cases of two biology laboratories operating at the California Institute of Technology. The two laboratories study gene regulatory networks, but (...) in remarkably different ways. The research strategy of the Davidson lab fits squarely into the traditional mechanist philosophy in its aim to decompose and reconstruct, in detail, gene regulatory networks of a chosen model organism. In contrast, the Elowitz lab constructs minimal models that do not attempt to represent any particular naturally evolved genetic circuits. Instead, it studies the principles of gene regulation through a template-based approach that is applicable to any kinds of networks, whether biological or not. We call for the mechanists to consider whether the latter approach can be accommodated by the mechanistic approach, and what kinds of modifications it would imply for the mechanistic paradigm of explanation, if it were to address modelling more generally.

This paper argues that the “long 1970s” (1969–1983) is an important though often overlooked period in the development of a rich landscape in the research of metabolism, development, and evolution. The period is marked by: shrinking public funding of basic science, shifting research agendas in molecular biology, the incorporation of new phenomena and experimental tools from previous biological research at the molecular level, and the development of recombinant DNA techniques. Research was reoriented towards eukaryotic cells and development, and in particular (...) towards “giant” RNA processing and transcription. We will here focus on three different models of developmental regulation published in that period: the two models of eukaryotic genetic regulation at the transcriptional level that were developed by Georgii P. Georgiev on the one hand, and by Roy Britten and Eric Davidson on the other; and the model of genetic sufficiency and evolution of regulatory genes proposed by Emile Zuckerkandl. These three cases illustrate the range of exploratory hypotheses that characterised the challenging landscape of gene regulation in the 1970s, a period that in hindsight can be labelled as transitional, between the biology at the laboratory bench of the preceding period, and the biology of genetic engineering and intensive data-driven research that followed.

ArgumentThis paper analyzes the research strategies of three different cases in the study of human genetics in Mexico – the work of Rubén Lisker in the 1960s, INMEGEN's mapping of Mexican genomic diversity between 2004 and 2009, and the analysis of Native American variation by Andrés Moreno and his colleagues in contemporary research. We make a distinction between an approach that incorporates multiple disciplinary resources into sampling design and interpretation, from one that privileges pragmatic considerations over more robust multidisciplinary analysis. (...) These choices have consequences for social, demographic, and biomedical practices, and also for accounts of genetic variation in human populations. While the former strategyunpacksfine-grained genetic variation – favoring precision and realism, the latter tends toflattenindividual differences and historical depth in lieu of generalization.

Reichenbachian approaches to indexicality contend that indexicals are "token-reflexives": semantic rules associated with any given indexical-type determine the truth-conditional import of properly produced tokens of that type relative to certain relational properties of those tokens. Such a view may be understood as sharing the main tenets of Kaplan's well-known theory regarding content, or truth-conditions, but differs from it regarding the nature of the linguistic meaning of indexicals and also regarding the bearers of truth-conditional import and truth-conditions. Kaplan has criticized these (...) approaches on different counts, the most damaging of which is that they make impossible a "logic of demonstratives". The reason for this is that the token-reflexive approach entails that not two tokens of the same sentential type including indexicals are guaranteed to have the same truth-conditions. In this paper I rebut this and other criticisms of the Reichenbachian approach. Additionally, I point out that Kaplan's original theory of "true demonstratives" is empirically inadequate, and claim that any modification capable of accurately handling the linguistic data would have similar problems to those attributed to the Reichenbachian approach. This is intended to show that the difficulties, no matter how real, are not caused by idiosincracies of the "token-reflexive" view, but by deep facts about indexicality. (shrink)

The paper examines an alleged distinction claimed to exist by Van Gelder between two different, but equally acceptable ways of accounting for the systematicity of cognitive output (two “varieties of compositionality”): “concatenative compositionality” vs. “functional compositionality.” The second is supposed to provide an explanation alternative to the Language of Thought Hypothesis. I contend that, if the definition of “concatenative compositionality” is taken in a different way from the official one given by Van Gelder (but one suggested by some of his (...) formulations) then there is indeed a different sort of compositionality; however, the second variety is not an alternative to the language of thought in that case. On the other hand, if the concept of concatenative compositionality is taken in a different way, along the lines of Van Gelder's explicit definition, then there is no reason to think that there is an alternative way of explaining systematicity.

Descriptive semantic theories purport to characterize the meanings of the expressions of languages in whatever complexity they might have. Foundational semantics purports to identify the kind of considerations relevant to establish that a given descriptive semantics accurately characterizes the language used by a given individual or community. Foundational Semantics I presents three contrasting approaches to the foundational matters, and the main considerations relevant to appraise their merits. These approaches contend that we should look at the contents of speakers’ intuitions; at (...) the deep psychology of users and its evolutionary history, as revealed by our best empirical theories; or at the personal-level rational psychology of those subjects. Foundational Semantics II examines a fourth view, according to which we should look instead at norms enforced among speakers. The two papers aim to determine in addition the extent to which the approaches are really rival, or rather complementary. (shrink)

Espino, Santamaria, and Garcia-Madruga (2000) report three results on the time taken to respond to a probe word occurring as end term in the premises of a syllogistic argument. They argue that these results can only be predicted by the theory of mental models. It is argued that two of these results, on differential reaction times to end-terms occurring in different premises and in different figures, are consistent with Chater and Oaksford's (1999) probability heuristics model (PHM). It is argued that (...) the third finding, on different reaction times between figures, does not address the issue of processing difficulty where PHM predicts no differences between figures. It is concluded that Espino et al.'s results do not discriminate between theories of syllogistic reasoning as effectively as they propose. (shrink)

ABSTRACTIn recent years, with Europe witnessing its worst refugee crisis since the Second World War, the process of applying for asylum in a foreign country has become the focus of numerous studies and research programs. The aim of the present article is to explore the subject through a case study of the issues and complexities surrounding the interpreting and translation services offered by the Spanish Asylum and Refugee Office. The data is based on two surveys: the first focused on the (...) professionals’ views of the role of translators and interpreters, and the second on translators and interpreters working in the field of international protection. The findings obtained from these studies may prove useful for improving the various interpreting and translation training programs and services that are crucial for managing the refugee crisis and the multiple problems associated with it.

Este trabajo examina el diálogo entre neokantismo, fenomenología y hermenéutica en el conocido como Kriegsnotsemester impartido por Martin Heidegger en 1919, y lo hace a la luz de las posibilidades allí abiertas para una reformulación contemporánea de la filosofía trascendental. A tal fin se abordará el análisis de las aporías que entraña la filosofía del valor en Windelband y Rickert y cómo la respuesta del joven Heidegger descubre un nuevo «espacio de sentido» en el que se mueve gran parte de (...) la filosofía actual. Desde esa dimensión preteórica del sentido será posible dar con el modo de acceso adecuado a la filosofía como «ciencia originaria». (shrink)

The United Nations World Tourism Organization has acknowledged 2020 as the worst year in tourism history due to the worldwide pandemic COVID-19. Destinations, tourists, local communities, stakeholders, and residents, and their daily activities were affected. Thus, wellbeing and resilience are two crucial variables to help the industry and the people recover. This research aims to analyze early positive approaches and attitudes to respond to the negative impact of COVID-19 in tourism everyday activities that have at its core wellbeing and resilience, (...) the two main variables of the Positive Psychology field of studies. A systematic literature review was conducted, following PRISMA guidelines to achieve this aim. The research was done using the Online Knowledge Library and all the available databases. The research led to 32 articles that were screened using the inclusion and exclusion criteria. A total of 18 scientific articles met all criteria. Overall, results show that a positive and resilient approach to deal with the adverse outcomes of the pandemic is a concern for stakeholders and the future of the organizations in the tourism and hospitality sector, as is tourists’ wellbeing. However, less research has been done on wellbeing and a clear lack of research regarding residents’ wellbeing and resilience is evident. A deeper study of wellbeing and resilience in tourism is needed, and actual practices and interventions to ensure that all tourism actors have the resources to overcome the pandemic and restart the industry’s daily lives feeling well and safe.

Haciendo uso de las bases de datos del Proceso de Admisión a la Educación Superior en Chile del año 2013, se analiza el comportamiento que tienen los componentes de Trayectoria Escolar y puntajes PSU con base a las variables de segmentación socioeducativa de los postulantes. No obstante ambos factores estar en teoría alineados con el currículum, las puntuaciones informan de una reducida correlación entre ellos. El objetivo es explorar y analizar la distribución de los puntajes que obtienen los postulantes en (...) los diferentes factores de selección con base a sus características socioeconómicas y educativas, además del impacto que tiene la incorporación del Ranking de Notas en la diversificación e inclusión de la población de estudiantes que anualmente participa de los procesos de selección. Los componentes trayectoria escolar, en especial el Ranking que establece la posición relativa del alumno dentro de su respectivo establecimiento, presentan distribuciones menos sesgadas y con mayor concentración hacia más altos puntajes en comparación a los del componente PSU, y se evidencian menos influenciados por variables sociofamiliares o económicas. El Ranking, como expresión del buen desempeño escolar, el esfuerzo y dedicación al estudio por parte del alumno, compensa los indeseables sesgos de selección haciendo más inclusiva la opción universitaria, cuyos efectos en la modificación del perfil del alumno seleccionado dependerá de la valoración que asigne la institución universitaria a la trayectoria escolar, en detrimento del tradicional componente PSU.

We examine the role of working memory's central executive in the mental model explanation of propositional reasoning by using two working memory measures: the classical “reading span” test by Daneman and Carpenter (1980) and a new measure. This new “reasoning span” measure requires individuals to solve very simple anaphora problems, and store and remember the word solution in a growing series of inferential problems. We present one experiment in which we check the involvement of the central executive in conditional and (...) disjunctive inference tasks and compare predictions of the new reasoning span test with those of the classical reading span test. The results of the experiment confirm that reasoning responses, which according to mental model theory require high cognitive work, are predicted by working memory measures. Results also show that some reasoning responses are probably obtained by means of superficial biases or strategies that do not load working memory. The reasoning span test, which involves the central executive to a greater degree, predicts reasoning performance better than the reading span test. The significance and possibilities of the new measure in studying reasoning are discussed. (shrink)

Por años, el sistema de selección universitaria ha enfrentado críticas por su intenso vínculo con características sociales y culturales de los y las postulantes, reproduciendo la segmentación que evidencia el espacio escolar. Para corregir estos sesgos, el año 2013 se incorporó el Ranking de notas como factor de ponderación, valorando componentes de trayectoria escolar y contexto educativo. El objetivo de este artículo es describir los impactos que ha tenido el Ranking de notas en el proceso de admisión 2018, en términos (...) de igualdad de oportunidades e inclusión de grupos. De metodología cuantitativa, este artículo usa bases de datos oficiales para realizar un análisis estadístico a los resultados de admisión 2018, construyendo índices y perfilando tendencias. Los resultados destacan el impacto positivo que ha tenido el Ranking sobre los puntajes ponderados y las tasas de selección, además de la compensación que hace a grupos históricamente relegados mediante la valoración del esfuerzo desplegado en contextos adversos. Las conclusiones argumentan que, si bien el Ranking es un eficiente mecanismo propulsor de mayor equidad en los procesos de selección universitaria, no es capaz de revertir la desigualdad y segmentación estructural del sistema educativo chileno.

Social and environmental ratings provided by social rating agencies are multidimensional. The first goal of our paper is to identify a small number of independent and relevant socially responsible (SR) dimensions reflecting a firms’ coherent posture toward social issues. We put forward that these dimensions are not exactly the same as the ESG ones (Environment, Social, and Governance). Using the six sub-ratings provided by the Vigeo rating agency, we perform a principal component analysis and we highlight three main independent SR (...) dimensions related to (1) business stakeholders (employees, customers, and suppliers), (2) societal stakeholders (environment and society), and (3) financial stakeholders (stockholders and debt holders). The second objective of our paper is to explore the link between stock returns and these three SR dimensions. Our most notable finding is that for each SR dimension, investors ask for an additional risk premium when they accept to hold non-socially responsible stocks. The cost of equity is thus lower for SR firms. The average premium over the period 2003–2010 is larger for the components “business stakeholders” and “financial stakeholders” than for the component “societal stakeholders.” The premium for this last component has only existed since the end of 2008. Since that time, environment and community involvement have become important risk factors strongly considered by investors. For the three dimensions, investors notably penalize large non-social firms and reward small social firms. (shrink)
