Background: SNOMED CT is a large terminology system designed to represent all aspects of healthcare. Its current form and content result from decades of bottom-up evolution. Due to SNOMED CT’s formal descriptions, it can be considered an ontology. The Basic Formal Ontology (BFO) is a foundational ontology that proposes a small set of disjoint, hierarchically ordered classes, supported by relations and axioms. In contrast, as a typical top-down endeavor, BFO was designed as a foundational framework for domain ontologies in the (...) natural sciences and related disciplines. Whereas it is mostly assumed that domain ontologies should be created as extensions of foundational ontologies, a post-hoc harmonization of consolidated domain ontologies in use, such as SNOMED CT, is known to be challenging. Methods: We explored the feasibility of harmonizing SNOMED CT with BFO, with a focus on the SNOMED CT Clinical Finding hierarchy. With more than 100,000 classes, it accounts for about one third of SNOMED CT’s content. In particular, we represented typical SNOMED CT finding/disorder concepts using description logics under BFO. Three representational patterns were created and the logical entailments analyzed. Results: Under a first scrutiny, the clinical intuition that diseases, disorders, signs and symptoms form a homogeneous ontological upper-level class appeared incompatible with BFO’s upper-level distinction into continuants and occurrents. The Clinical finding class seemed to be an umbrella for all kinds of entities of clinical interest, such as material entities, processes, states, dispositions, and qualities. This suggests the conclusion that Clinical finding would not be a suitable upper-level class from an BFO perspective. On closer inspection of the taxonomic links within this hierarchy and the implicit meaning derived thereof, it became clear that Clinical finding classes do not characterize the entity (e.g. a fracture, allergy, tumor, pain, hemorrhage, seizure, fever) in a literal sense but rather the condition of a patient having that fracture, allergy, pain etc. This gives sense to the current characteristic of the Clinical Finding hierarchy, in which complex classes are modeled as subclasses of their constituents. Most of these taxonomic links are inferred, as the consequence of the ‘role group’ design pattern, which is ubiquitous in SNOMED CT and has often been subject of controversy regarding its semantics. Conclusion: Our analyses resulted in the proposal of (i) equating SNOMED CT’s ‘role group’ property with the reflexive and transitive BFO relation ‘has occurrent part’; and (ii) reinterpreting Clinical Findings as Clinical Occurrents, i.e. temporally extended entities in an organism, having one or more occurrents as temporal parts that occur in continuants. This re-interpretation was corroborated by a manual analysis of classes under Clinical Finding, as well as the identification of similar modeling patterns in other ontologies. As a result, SNOMED CT does not require any content redesign to establish compatibility with BFO, apart from this re-interpretation, and a suggested re-labeling. Regarding the feasibility of harmonizing terminologies with principled foundational ontologies post-hoc, our results provide support to the assumption that this does not necessarily require major redesign efforts, but rather a careful analysis of the implicit assumptions of terminology curators and users.

The translational research community, in general, and the Clinical and Translational Science Awards (CTSA) community, in particular, share the vision of repurposing EHRs for research that will improve the quality of clinical practice. Many members of these communities are also aware that electronic health records (EHRs) suffer limitations of data becoming poorly structured, biased, and unusable out of original context. This creates obstacles to the continuity of care, utility, quality improvement, and translational research. Analogous limitations to sharing objective data in (...) other areas of the natural sciences have been successfully overcome by developing and using common ontologies. This White Paper presents the authors’ rationale for the use of ontologies with computable semantics for the improvement of clinical data quality and EHR usability formulated for researchers with a stake in clinical and translational science and who are advocates for the use of information technology in medicine but at the same time are concerned by current major shortfalls. This White Paper outlines pitfalls, opportunities, and solutions and recommends increased investment in research and development of ontologies with computable semantics for a new generation of EHRs.

The variety of devices and the socialization of consumption have decentralized access to online information which is not retrieved directly from media websites but through social networks. These same factors have driven user interest towards a wider range of both ‘hard’ and ‘soft’ topics. The aim of this article is to identify the consumption of news on these topics among digital users in Spain. The methodology used is based on an analysis of the survey conducted as part of the Digital (...) News Report 2017. Following this analysis, a conclusion has been reached that the most popular hard news stories in Spain are those related to the local and regional community itself, and to health and education, while the most popular soft news stories relate to lifestyles and arts and culture. The analysis has revealed that increased interest in news and greater topic specialization result in more diversified use of sources, formats, and complementary routes. (shrink)

This is an interpretative, critical, and selective review of scholarly contributions that explore Latin America’s religious landscape. We present data, both qualitative and quantitative, from Latin America and analyze the explanations given to make sense of it. After assessing the literature that uses either secularization theory or the “religious economy” approach, we study explanations that highlight a Latin American style of “popular religiosity.” These three models, in different ways, put the emphasis on religious institutions—their vitality, commands, competition, and authority. We (...) propose, instead, a focus on the religious practices of regular believers. We speculate that embarking from that focus, the idea of an “enchanted modernity” will help make sense of Latin America’s religious landscape. Nuanced elucidation of Latin America’s religious particularities will situate them in dialogue with other regions of the world, like western Europe and the United States, while also acknowledging the fact that Latin America is experiencing a modernization process distinct from the North Atlantic one.

BackgroundStudies and meta-analyses found individual, meso and micro-social factors that are associated with individual well-being, as well as a positive socio-emotional climate or collective well-being.AimThis article simultaneously studies and examines these factors of well-being.MethodWell-Being is measured as a dependent variable at the individual and collective level, as well as the predictors, in three cross-sectional and one longitudinal studies. Education and social intervention workers from Chile, Spain and Uruguay participate; a subsample of educators from the south central Chile and from Chile, (...) Uruguay and Spain ; workers from organizations in Latin America and Southern Europe, military cadets from Argentina ; and teams from Spanish companies.ResultsIndividual and collective well-being indicators were related, suggesting that the emotional climate as a context improves personal well-being. Individual factors, psychosocial factors were positively associated with personal well-being in education and social intervention context. Organizational dynamic or transformational culture is directly and indirectly associated with individual well-being through previously described psychosocial factors. Group processes such as internal communication and safe participation, task orientation or climate of excellence as well as leadership style that reinforces participation and belonging, were positively associated with collective well-being in labor and military context and predict team work socio-emotional climate in a longitudinal study- but were unrelated to individual well-being. Transformational leadership plays a mediating role between functional factors and social-emotional climate in work teams. Organizational role autonomy, functional organizational leadership, integration and resources were associated with collective well-being in organizations. Organizational leadership moderates the relationship between task orientation and collective well-being in military context.ConclusionIndividual and microsocial factors influence personal well-being. Meso level factors favorable to well-being through processes which reinforce social belonging, influence directly collective well-being and indirectly personal well-being. Leadership that reinforces participation and belonging play a central role for emotional climate. Stress and emotional climate playing an important pivotal role for psychological well-being.

Desde tiempos remotos la apariencia ha sido uno de los instrumentos más importantes en el hombre para expresar sus sentimientos e ideologías. Como una seña de identidad ha servido siempre para establecer el orden social y el rango de cada individuo. Los monarcas conscientes del poder de la imagen, utilizaron todos los elementos a su alcance para conquistar a través de la vista a sus súbditos. La indumentaria, sus adornos, gestos y actitudes, sirvieron para suscitar la admiración y el respeto. (...) En esta escenografía el rey se presentaba como figura principal rodeado en numerosas ocasiones de su familia, jugando sus hijos un papel fundamental como continuadores de su estirpe. En España, donde no existía la ley sálica, la Infanta, como descendiente y posible heredera del rey, tenía la misión de reflejar los valores de su dinastía y asegurar su supervivencia. Isabel Clara Eugenia yCatalina Micaela, hijas de Felipe II e Isabel de Valois, encarnaron el poder de la monarquía absoluta de su padre y contribuyeron a personificar sus virtudes. A través de sus retratos y de diferentes documentos de los Archivos Generales de Palacio y de Simancas, el presente trabajo analiza la apariencia y la representación de las infantas Isabel Clara Eugenia yCatalina Micaela en la corte de Felipe II.

Humans can consolidate and carry out habits other animals cannot. This statement is mainly sustained by the fact that humans have a unique cognitive control of their actions: we can let our attention fade away to perform automatic tasks more efficiently, we can detect if there has been an unexpected problem in their implementation, and we can regain conscious control of the action if necessary. We tend to dichotomize this cognitive process into two “systems”, namely goal-directed versus habitual (Dickinson, 1985), (...) conscious versus unconscious (Crick and Koch, 1998), or slow versus fast (Kahneman, 2011). If we just put it in those terms, these two ways of tackling the challenges of a changing environment seem to be present in non-human animals. However, all dichotomies imply a difficulty to deal with: the regulation of the transition between the two systems. Is this carried out by a third element, or regulated by one of the systems? Could it be more convenient to view it as a continuum, rather than a dichotomy? In any case, we believe this transition has a level of complexity in humans that makes it qualitatively different from its analogue in animals. In fact, this ‘cognitive bridge’ might be a major feature to characterize a reliable behavior, since a particular task or problem is more efficiently tackled when the transition between the two systems is more adequate. Moreover, the integrity of this link could be an indicator to detect prodromal psychiatric conditions, as it has been suggested for slips-of-action (Gillan et al., 2011). In order to justify these ideas, we will focus first on Kahneman’s distinction between systems 1 and 2 (Kahneman, 2011). On the one hand, System 1 is responsible for making decisions rapidly. The purpose of this system is to give us an assessment of the environment around us as quickly as possible so that we are able to respond as fast as possible. To perform this task, System 1 follows general rules or guidelines (heuristics). In all, System 1 is intended to help us make decisions more quickly, and is very useful (let’s say ‘just fine’) in most cases. However, one of the characteristics of these decisions is the lack of voluntary control, what is a problem considering this system is responsible of many of the decisions and judgments we make. Given to its “automatic” nature, System 1 also has biases and systematic errors that are likely to happen in some situations.On the other hand, System 2 acts when a problem which System 1 has no solution for arises. System 2, apparently, can take control of the whole process at any time. It is somewhat triggered by some external or internal alarm that draws its attention and makes it take “conscious” control of the situation. One of the problems of this system is that it is lazy and can be easily exhausted. Therefore, it usually accepts the decisions of System 1 without monitoring them. One proof of System 2’s negligence is what Kahneman calls WYSIATI ("What You See Is All There Is"), a general rule that “facilitates the achievement of coherence and of the cognitive ease that causes us to accept a statement as true”. System 1 easily gets that coherence, and System 2 usually allows it to jump to conclusions and act. In different sets of experiments, Kahneman demonstrates that humans are not good at all with statistics or handling mathematics; in his opinion, this is because humans simplify judgments to make them more understandable and deal with them just through heuristics that System 1 can handle. This general view of humans as poor rational decision-makers is also supported by other authors (see, for example, Ariely, 2008).In our opinion, this division of human cognition into two systems fits well with the usual opposition between goal-directed versus habitual systems (Dickinson, 1985). In general, goal-directed actions are viewed as conscious, flexible, and sensitive to outcome devaluation, whereas habits are mainly unconscious, rigid and insensitive to changes in the value of the outcome. The features of goal-directed and habit systems were mainly drawn from studies in animals. The typical experiment about this subject consists on teaching the contingency between an instrumental action (for example, a lever press) and a reward to the animal (Adams and Dickinson, 1981). At the beginning, the animal’s behavior is goal directed, and it performs the action to obtain the reward. However, this behavior becomes “habitual” (in this context, a motor routine) after many repetitions. When that happens, the value of the reward is transferred to the lever press itself: even though the outcome is devalued (gets the animal sick) or the animal is sated, it keeps pressing the lever. This is why habits have been opposed to goal-directed behavior.A quick look suggests that habits and goal-directed actions are intimately related to Systems 1 and 2, respectively. This is also supported by the identification of the goal-directed system with a model-based reinforcement learning scheme, since it can be viewed “in terms of sophisticated, computationally demanding, prospective planning, in which a decision tree of possible future states and actions is built using a learned internal model of the environment” (Dolan and Dayan, 2013). The habitual system, on the other hand, follows a model-free scheme, which “is computationally efficient, since it replaces computation (i.e., the burdensome simulation of future states) with memory (i.e., stored discounted values of expected future reward); however, the forward-looking nature of the prediction error makes it statistically inefficient” (Dolan and Dayan, 2013). Following these analogies between systems, we can assume that some actions that at the beginning fall under the domain of System 2 might be transferred to System 1 through learning, like goal-directed actions become habits through experience.Concerning the neural bases of these systems, the striatum and its cortical afferents and –indirect– target areas in the cortex play a major role. It is widely accepted that the cognitive part of the striatum –caudate nucleus and anterior putamen– are involved in the planning and execution of goal-directed actions, together with the prefrontal cortex (Balleine et al., 2007). On the other hand, the sensorimotor striatal aspects –mainly the posterior putamen– and the supplementary motor area of the cortex are particularly active when the agent is performing a well-learned action (Ashby et al., 2010; Miyachi et al., 2002). Furthermore, the activity of the neurons in these areas follows a “chunked” pattern: they are mainly active at certain stages of the motor routine (for example at the beginning and the end of the sequence, when a particular switch or turn is needed, etc), and this activity is reduced in the rest of the motor sequence (Graybiel, 1998). Although some authors question a sharp neuroanatomical basis of Kahneman’s Systems 1 and 2 (Gold and Shadlen, 2007), our train of thought in this manuscript suggests that the more reflective System 2 should be based in the prefrontal cortex –both dorsal and ventral–, and the cognitive regions of the basal ganglia. Likewise, the more automatic System 1 would lie on motor and premotor cortical regions, as well as on the sensorimotor aspects of those subcortical nuclei.This neuroscientific framework identifies the habit system with automaticity, rigidity and unconsciousness; however, we are intending to challenge this view in past and forthcoming contributions (Bernacer et al., 2014; Bernacer and Gimenez-Amaya, 2013). In a nutshell, we propose to view the phenomenon of action from the point of view of the agent as a whole, and not from an isolated movement. Hence, it could be more convenient to understand System 1 –or habits– as a resource of System 2, rather than as opposed systems in competition. Whereas a motor routine (i.e., what is commonly called “habit” in neuroscience) implies the sequential and unconscious performance of movements, they usually pursue the goal set by the agent. In fact, the more engrained the routine is, the easier for the agent to achieve that goal. Furthermore, the agent can consciously stop or correct the movement at any point, since the habit releases the higher cognitive regions of the brain to improve the performance of the action. A very simple example of this is a tennis service, which should be “goal directed” to place the ball wherever the player wants. It involves a set of movements such as throwing the ball upwards, moving the feet, putting the arm back, etc. Only when these motor routines are learned correctly, the player is able to concentrate on other aspects of the service such as the speed, spin, or exploiting the weaknesses of the receiver. This can be also exemplified with other kinds of habits such as driving, playing an instrument, tackling a mathematical problem, and so on. They all suggest that “automatic” routines are governed by higher cognitive functions to better achieve a particular goal.Kahneman’s Systems 1 and 2 allow as well this release of consciousness from everyday decisions to focus on more complicated situations. As Kahneman himself and other authors defend (Ariely, 2008), the problem arises when System 2 is rarely used or either system is applied to inadequate situations. However, we believe that the most effective agent does not exclusively rely on System 2, but efficiently uses all resources of ‘each system’ in the right situation and, more importantly, carries out an appropriate transition between them. That is, in our opinion, a ‘rational’ agent. This could be also said about goal-directed and habitual systems. Moreover, we believe that this transition between systems is subject to learning, and it can be performed more effectively through experience.If we understand these fragmentations of cognition as independent systems in competition, we encounter an important problem: is there an additional mechanism in charge of the transition between systems, or is this regulated by one of the systems itself? If the first option were true, we would find the difficulty of defining the nature –both conceptually and anatomically– of a “third system” qualitatively different than the other two. This would lead us to an ad infinitum process –the need of a fourth element to regulate the activity of the third, and so on–, and therefore we believe this hypothesis should be rejected. Considering the second option, it seems that only the highly cognitive System 2 could be in charge of leading the transition between systems, which in turn dissolves a rigorous separation in two systems. The role of System 2 in leading the transition is clear when the agent decides to regain conscious control of a task generally performed in an unconscious manner. In this sense, the interaction of the orbitofrontal cortex with either the cognitive or sensorimotor aspects of the striatum plays a central role in shifting between goal-directed actions and motor routines (Gremel andCosta, 2013). In other situations, an external cue such as an error may set the alarm for System 2 to retake control of the action. Regarding this, the anterior cingulate cortex has been reported to be active in highly-conflictive decision making situations (Goñi et al., 2011); for that reason, some authors relate this cortical area with error monitoring (Carter, 1998; Botvinick et al., 2004). A recent report suggests a new model of reinforcement learning and conflict monitoring, which involves a wide network including different areas of the cortex (posterior parietal, precentral, anterior cingulate and prefrontal) and the basal ganglia (Zendehrouh et al., 2013).To sum up, this opinion article suggests viewing Kahneman’s systems as analogous to the goal-directed/habits dichotomy in order to improve the understanding of some aspects of human cognition. Further, we believe a strict separation between systems in competition is problematic, since System 2 is always in charge of governing the interplay between systems: therefore, System 1 –or habits– should be understood as a resource of System 2. This view could shed some light on the understanding of habits as a source of learning, plasticity and freedom for the agent. Finally, an inappropriate cognitive control of habits could be an indicator of certain psychiatric conditions. (shrink)

This study explores the efficacy of a specific tool – the articulation of the ideal self – in job engagement, psychological well-being, and organizational citizenship behavior. We hypothesized that employees who can visualize their jobs as part of their ideal self – in particular how it helps in its development and realization – would feel higher levels of engagement and fulfillment in their lives, as well as engage in greater amounts of helping and voice OCB. A total of 239 full (...) time employees from five companies inCosta Rica filled out the ideal self questionnaire, the job engagement, and psychological well-being surveys, and were evaluated by their peers on task behavior and helping and voice OCB. Results of the SEM model showed that the ideal self was positively related to job engagement, psychological well-being and helping and voice. These findings contribute to the research on the impact and importance for organizations to help employees find meaningfulness in their work. (shrink)

Renal replacement therapy is the indicated treatment for individuals with chronic kidney disease (CKD) to survive. However, not all sick people have access to the same treatment. This study compares renal care in two developing countries with different health systems. Specifically, it explores hemodialysis treatment from the perspective of low‐income individuals. A qualitative, comparative study was performed in Brazil and Mexico. Using purposive sampling, the research was based on open‐ended interviews with nineteen participants with kidney failure undergoing hemodialysis treatment in (...) public hospitals and ten relatives. According to our results, Brazilian participants perceived hemodialysis care as satisfactory because of health personnel courtesy as well as free access to dialysis treatment, prescription drugs, hospitalization and transportation. However, they reported deficiencies in the care they were receiving due to shortages of specialists, prescription drugs, laboratory tests and transportation. Mexican participants, in contrast, highlighted the catastrophic costs of medical care because they had no free access to renal therapy, nor adequate financial resources. Our findings suggest that low‐income Brazilian CKD sufferers experience renal care differently, as they are more satisfied and face less obstacles with hemodialysis compared with those of Mexico. More studies on the topic are needed. (shrink)

Philosophical discussions on cognition (ranging from computational and representational approaches to the 4E fra-mework), on the one hand, and those on sound and auditory per-ception, on the other, have hitherto remained apart. In this paper, the author addresses the concept of “auditory cognition”. While committing to the conceptual analysis of the latter, the author in-troduces the discussion of modality-specif ic approaches. Since the contributions made so far in the domain of the philosophy of sound and auditory perception are prone to (...) favor computational-repre-sentational approaches —e.g., the perceptual coherence model (Méndez-Martínez, 2022)—, the exploration of 4E possibilities will lay down a series of questions aimed to encourage future developers from that viewpoint. In that sense, the author explores conceptual entailments and connections between the genealogy of theories within the philosophy of sound and auditory perception, and the hypothesis of the extended cognition (EX).

Bergson reconoce a Kant el mérito de haber caracterizado al espacio y al tiempo homogéneos como actos del espíritu distintos de todo contenido sensible. Le reprocha no haber advertido que su función no es especulativa sino práctica. De ahí la posibilidad de la metafísica como conocimiento de la duración, una vez superado el mecanismo espacializante de la inteligencia.

Most models of lexical access assume that bilingual speakers activate their two languages even when they are in a context in which only one language is used. A critical piece of evidence used to support this notion is the observation that a given word automatically activates its translation equivalent in the other language. Here, we argue that these findings are compatible with a different account, in which bilinguals “carry over” the structure of their native language to the non-native language during (...) learning, and where there is no activation of translation equivalents. To demonstrate this, we describe a model in which language learning involves mapping native language phonological relationships to the non-native language, and we show how it can explain the results attributed to automatic activation of translation equivalents.

We apply the recently elaborated notions of 'pragmatic truth' and 'pragmatic probability' to the problem of the construction of a logic of inductive inference. It is argued that the system outlined here is able to overcome many of the objections usually levelled against such attempts. We claim, furthermore, that our view captures the essentially cumulative nature of science and allows us to explain why it is indeed reasonable to accept and believe in the conclusions reached by inductive inference.

Este artículo examina cuestiones y desarrollos de la Crítica de la Economía Política de Marx que permiten abordar las relaciones de género en el capitalismo. Para ello, se analizan la especificidad de la dominación capitalista, los límites de la crítica de Marx para abordar cuestiones de género y su potencial desarrollo a partir de la relación entre la reproducción de la fuerza de trabajo y de la totalidad social. Siguiendo esta línea, se exponen críticamente los desarrollos de la crítica de (...) Marx que han llevado a cabo el colectivo Endnotes y R. Scholz para analizar la relación interna entre género y capital. Estas propuestas plantean la existencia de un otro del valor vinculado material y simbólicamente a las categorías «mujer» y «feminidad». Se trata, en última instancia, de pensar la especificidad de la opresión de género en el capitalismo y la forma que adopta en la actualidad. (shrink)

We propose a formalization of Meinong's theory of objects with the help of Hilbert's $\epsilon$-symbol and a paraconsistent logical system, with an eye towards its application in an axiomatization of the natural sciences.

O presente trabalho pretende apresentar o conceito de ambivalência no pensamento de Winnicott, discutindo suas características no estágio do concernimento. A partir da teoria do amadurecimento humano, serão tematizados alguns elementos dos estágios anteriores ao alcance da identidade unitária, que podem ser considerados condições para a constituição da ambivalência. Sendo assim, será apresentado como, na saúde, durante o estágio do concernimento, ocorrem tanto o alcance da ambivalência como a capacidade para a manutenção dessa conquista ao longo da vida. Por fim, (...) algumas contribuições, a partir da compreensão winnicottiana do alcance, da perda ou do não-alcance da capacidade para a ambivalência, serão apresentadas como possibilidades para pesquisas no campo psicanalítico.
