El objetivo de este artículo es describir la percepción de riesgo y los factores de protección y de riesgo frente al consumo de sustancias psicoactivas legales e ilegales en estudiantes de la Universidad de Boyacá. Es un estudio cuantitativo y descriptivo de corte transversal, para el cual se tomó una muestra de 573 estudiantes que fueron seleccionados mediante muestreo estratificado probabilístico. El instrumento utilizado fue la encuesta sobre consumo de drogas, factores y percepción de riesgo en estudiantes universitarios (CODEU) diseñado (...) por Beverido, Salas, De San Jorge, Pavón, Blázquez, Gogeascoechea y Cruz (2012), que consta de 73 preguntas. Este instrumento fue validado y obtuvo un alpha de Cronbach de 0.787. Los hallazgos muestran que entre los factores protectores se encuentran: adecuadas relaciones familiares y practicar un deporte, como factores de riesgo se identifican principalmente: la permisividad social y las construcciones de reconocimiento social presentes ante el consumo de sustancias legales. De las sustancias ilegales, la marihuana es la que se percibe como de menor riesgo frente a la cocaína, el bazuco, los inhalantes y la heroína. (shrink)

Pedro Álvarez (Cuba) y Rafael Trelles (Puerto Rico) son dos importantes exponentes de la plástica contemporánea en el Caribe hispano que encontraron en dos hitos artísticos del siglo xix una vía para cuestionar las fórmulas fijadas por la Historia y el Arte. Ambos, a partir de la reapropiación de la obra de Víctor Patricio Landaluze y Francisco Oller, respectivamente, reflexionan sobre las complejas circunstancias de sus islas. Mediante el estudio del pasado ambos se preocupan comprometidamente por el sentido de su (...) historia patria, por la (re) actualización de su tradición artística o las funciones del intelectual en la configuración de sus contextos nacionales. La fragmentación y el collage resultan métodos constructivos eficaces que utilizan ambos artistas para descontextualizar los múltiples signos culturales de sus referentes de partida y readecuar sus múltiples significados en la nueva obra, y en el nuevo contexto. Sin embargo, a pesar de las semejanzas se advierten igualmente diferencias de intención, de acuerdo a las respectivas realidades nacionales. (shrink)

This article has a dual purpose: on the one hand, it aims to add to the study of text production from a formulation-centered perspective ; on the other, since the analysis and discussion of linguistic problems presented here focus on a specific discourse type within scientific communication, this article is intended as a contribution to scientific communication studies. As I am particularly interested in text production as a process, the corpus I examine consists of oral interviews. In particular, I explore (...) the oral interaction between scientists and specialized journalists that precedes the writing of science popularization texts targeted for the lay reader. I analyze and assess, from a structural and functional point of view, two types of recurrent formulation procedures usually deployed by experts: `illustration' and `reformulation', and claim they constitute resources for the construction of the interlocutors' discursive identities.

BackgroundThis pilot study aims to test the usability of the iACTwithPain platform, an online ACT-based intervention for people with chronic pain, to obtain information on which intervention and usability aspects need improvement and on expected retention rates.MethodsSeventy-three Portuguese women with chronic pain were invited to complete the first three sessions of the iACTwithPain intervention assess their quality, usefulness and the platform’s usability. Twenty-one accepted the invitation. Additionally, eight healthcare professionals working with chronic medical conditions assessed the platform and the intervention (...) from a practitioner’s point of view.ResultsThis study presented a considerable attrition rate (71.43%) among chronic pain participants, with six completers. There were no significant differences in demographic or clinical variables between dropouts and completers except for completed education (participants who dropped out presented less education than completers). Reasons for dropout were related to difficult personal events occurring during the time of the intervention, lack of time, or having forgotten. There seemed to be an overall satisfaction with both the intervention, its contents and form of presentation of information, and the platform, concerning its design, appearance, and usability. Real image videos were preferred over animations or audio by chronic pain participants. Healthcare professionals emphasized the appealing and dynamic aspects of the animation format.ConclusionThis study informs the ongoing improvement of the iACTwithPain platform and provides valuable information on aspects researchers should consider while developing online psychological interventions for chronic pain. Further implications are discussed. (shrink)

Une esthétique de la Mort.

À l’adolescence, le mouvement de désaffiliation peut constituer un élément structurant de l’évolution subjective et la transformation identitaire qui s’ensuit une maturation vers l’âge adulte. Toutefois, dans beaucoup de ces cas de bascule identitaire, la désaffiliation se fait de manière abrupte, secrète, dans un refus total des valeurs des parents et des parents eux-mêmes. Les facteurs qui aboutissent à la désaffiliation familiale sont multiples : fragilité de la construction du moi, défaillances des structures sociales et du fonctionnement familial, primauté de (...) valeurs de performance et de rapidité au détriment des liens. À partir d’une situation clinique de couple recomposé, l’auteur essaye d’analyser les effets des facteurs familiaux, incluant les diverses alliances inconscientes, qui contribuent à une transformation identitaire marquée chez un des enfants. Celle-ci, tournée vers la religion et l’idéologie, s'assoit sur une base de revalorisation narcissique et un chaos de la transmission. (shrink)

A natural extension of Natural Deduction was defined by Schroder-Heister where not only formulas but also rules could be used as hypotheses and hence discharged. It was shown that this extension allows the definition of higher-level introduction and elimination schemes and that the set $\{ \vee, \wedge, \rightarrow, \bot \}$ of intuitionist sentential operators forms a {\it complete} set of operators modulo the higher level introduction and elimination schemes, i.e., that any operator whose introduction and elimination rules are instances of (...) the higher-level schemes can be defined in terms of $\{ \vee, \wedge, \rightarrow, \bot \}$.The aim of the present work is to extend the well-known connections between Proof Theory and Category Theory to higher-level Natural Deduction. To be precise, we will show how an adjointness between cartesian closed categories with finite coproducts can be associated, in a systematic way, with any operator $\phi$ defined by the higher-level schemes. The objects in the categories will be rules instead of formulas. (shrink)

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 tries to characterize the factors determining human relations with its environment and to identify the drives of those behavioral patterns and “praxis”. One scrutinizes the physiological and psychological factors that influence those drives, and tries to determine ways of overriding instinctive drives in favor of rational, sustainable ones. It focuses its attention on the way the different ecosystemic, economic and socio-cultural systems work, and pin-points the critical issues in view of the development of sustainable behavioral patterns. Also the (...) values that must build the new behavioral paradigm, as well as the ways to ensure the evolutionary quantum-leap necessary to ensure this sustainable condition, and the fulfilment, at every level, the different needs of humans and human societies, are analyzed. In conclusion, it stresses the fact that any reliable and long lasting change towards a sustainable behavior must start at the individual and the close social groups levels, and of the development of new factors of self-fulfillment and gratification, able to support and foster that change. The proposed epistemological approach is particularly innovative, precisely because of this emphasis on the individual drives and the way they determine the global patterns of environmental use, as well as the way they can evolve into a more rational character. In short, the paper focuses itself in the way man can evolve from its natural animal instincts and drives toward more rational ones, humanizing its behavior and turning, therefore, into an able actor of the process of sustainability building.

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)

RESUMEN El artículo examina las limitaciones de un enfoque de restitución de derechos de pro piedad con resonancias en el derecho civil y su forma de narrar el sujeto propietario y la cosa-bien apropiada, para abordar las experiencias de daño sufridas por campe sinos desplazados y despojados en Colombia. Esa narración reafirma la separación entre personas y cosas, estrecha la potencialidad significativa de las relaciones entre campesino y tierra, y limita el campo interpretativo del daño y la reparación, donde las (...) experiencias de quienes son dañados no son escuchadas. ABSTRACT The article examines the limitations of the restitution of property rights approach, with its repercussions for on civil law, and its way of narrating the subject-owner and the thing-good appropriated, in order to address the experiences of harm suffered by displaced and dispossessed peasants in Colombia. Such narration reaffirms the separation between persons and things; reduces the significant potentiality of the relations between peasants and land; and limits the interpretive field of harm and reparation since the experiences of those harmed are not heard.

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)

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.

Background Moral resilience is the integrity and emotional strength to remain buoyant and achieve moral growth amid distressing situations. Evidence is still emerging on how to best cultivate moral resilience. Few studies have examined the predictive relationship of workplace well-being and of organizational factors with moral resilience. Research aims The aims are to examine associations of workplace well-being (i.e., compassion satisfaction, burnout, and secondary traumatic stress) and moral resilience, and to examine associations of workplace factors (i.e., authentic leadership and perceived (...) congruence of organizational mission and behaviors) and moral resilience. Research design This study uses a cross-sectional design. Participants and research context: Nurses practicing in a hospital in the United States were surveyed using validated instruments (N = 147). Individual factors were measured using demographics and the Professional Quality of Life Scale. Organizational factors were measured using the Authentic Leadership Questionnaire and a single item measuring organizational mission/behavior congruence. Moral resilience was measured using the Rushton Moral Resilience Scale. Ethical considerations The study was approved by an institutional review board. Findings Resilience was noted to have significant small correlations with burnout, secondary traumatic stress, compassion satisfaction, and organizational mission/behavior congruence. Burnout and secondary traumatic stress predicted less resilience, whereas compassion satisfaction and perceived congruence between organizational mission and behaviors predicted higher resilience. Discussion Burnout and secondary traumatic stress, increasingly experienced by nurses and other health professionals, have negative effects on moral resilience. Compassion satisfaction can increase resilience, which is especially important in nursing. Organizational practices promoting integrity and confidence can have positive effects on resilience. Conclusions Continued work to confront workplace well-being issues, especially burnout, is needed as a way of increasing moral resilience. Studies of organizational and work environment factors to bolster resilience are likewise needed to assist organizational leaders in devising the best strategies. (shrink)

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)

Between December 14 and 20, 1965, the World Health Organization Scientific Group on Haemoglobinopathies and Allied Disorders metatthe Geneva agency's headquarters. The group comprised eight well-known physicians including Tulio Arends, a leading Latin American human geneticist from the Venezuelan Institute for Scientific Investigations. Others came from North America, Northern and Southern Europe, the Middle East and South East Asia, an array that reflected the delicate geopolitical equilibriums of postwar international health programs, but also the development of highly specialized biomedical research (...) around the globe. They elected Herman Lehmann, from the Abnormal Haemoglobin Research Unit of the Medical Research... (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.

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.

Christopher Hom has recently argued that the best-overall account of the meaning of pejorative terms is a semantic account according to which pejoratives make a distinctive truth-conditional contribution, and in particular express complex, negative socially constructed properties. In addition, Hom supplements the semantic account with a pragmatic strategy to deal with the derogatory content of occurrences of pejorative terms in negations, conditionals, attitude reports, and so on, according to which those occurrences give rise to conversational implicatures to the effect that (...) the pejorative terms are non-empty, which explains the offensiveness of those occurrences. In this paper, I aim to defend this semantic strategy from several recent objections, and I will also present a novel objection, which in my view shows that we should understand the semantic account as a version of inferentialism, rather than radical externalism.

Despite the promises made by molecular evolutionists since the early 1960s that phylogenies would be readily reconstructed using molecular data, the construction of molecular phylogenies has both retained many methodological problems of the past and brought up new ones of considerable epistemic relevance. The field is driven not only by changes in knowledge about the processes of molecular evolution, but also by an ever-present methodological anxiety manifested in the constant search for an increased objectivity—or in its converse, the avoidance of (...) subjectivity.This paper offers an exhaustive account of the methodological and conceptual difficulties embedded in each of the steps required to elaborate molecular phytogenies. The authors adopt a historical perspective on the field in order to follow the development of practices that seek to increase the objectivity of their methods and representations. These include the adoption and development of explicit criteria for evaluation of evidence, and of procedures associated with methods of statistical inference, quantification and automation. All these are linked to an increasing use of computers in research since the mid 1960s. We will show that the practices of objectivity described are highly dependent on the problems and tools of molecular phylogenetics. (shrink)

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.

What does woman mean? According to two competing views, it can be seen as a sex term or as a gender term. Recently, Jennifer Saul has put forward a contextualist view, according to which woman can have different meanings in different contexts. The main motivation for this view seems to involve moral and political considerations, namely, that this view can do justice to the claims of trans women. Unfortunately, Saul argues, on further reflection the contextualist view fails to do justice (...) to those moral and political claims that motivated the view in the first place. In this article I argue that there is a version of the contextualist view that can indeed capture those moral and political aims, and in addition, I use this case to illustrate an important and more general claim, namely, that moral and political considerations can be relevant to the descriptive project of finding out what certain politically significant terms actually mean.

En su trabajo acerca del debate Putnam-Rorty, Luis Robledo supone una concepción reduccionista de la justificación en Rorty, y defiende contra ella la indepen-dencia entre justificación y consenso, a través del argumento de la posibilidad de un consenso sin justificación. A su juicio, el no sostener una independencia tal conduciría a problemas desfavorables para el pragmatismo. En este trabajo buscaré presentar una interpretación alternativa y no reduccionista de la justificación rortiana, que aún sin reconocer una total independencia entre ambas instancias, (...) no sólo evita estos proble-mas, sino que además muestra que es poco pragmático el ejemplo proporcionado por Robledo en su argumentación.

In this paper I discuss the question of what it means to say that a property is socially constructed. I focus on an influential project that many social constructivists are engaged in, namely, arguing against the inevitability of a trait, and I examine several recent characterizations of social construction, with the aim of assessing which one is more suited to the task.

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)

The metaphysics of gender and race is a growing area of concern in contemporary analytic metaphysics, with many different views about the nature of gender and race being submitted and discussed. But what are these debates about? What questions are these accounts trying to answer? And is there real disagreement between advocates of differ- ent views about race or gender? If so, what are they really disagreeing about? In this paper I want to develop a view about what the debates (...) in the metaphysics of gender and race are about, namely, a version of metaphysical deflationism, according to which these debates are about how we actually use or should use the terms ‘gender’ and ‘race’ (and other related terms), where moral and political considerations play a central role. I will also argue that my version of the view can overcome some recent and powerful objections to metaphysical deflationism of- fered by Elizabeth Barnes (2014, 2017). (shrink)
