Alcohol use disorder is a burden to society creating social and health problems. Detection of AUD and its effects on the brain are difficult to assess. This problem is enhanced by the comorbid use of other substances such as nicotine that has been present in previous studies. Recent machine learning algorithms have raised the attention of researchers as a useful tool in studying and detecting AUD. This work uses AUD and controls samples free of any other substance use to assess (...) the performance of a set of commonly used machine learning classifiers detecting AUD from resting state functional network connectivity derived from independent component analysis. The cohort used included 51 alcohol dependent subjects and 51 control subjects. Despite alcohol, none of the 102 subjects reported use of nicotine, cannabis or any other dependence or habit formation substance. Classification features consisted of whole brain rsFNC estimates undergoing a feature selection process using a random forest approach. Features were then fed to 10 different machine learning classifiers to be evaluated based on their classification performance. A neural network classifier showed the highest performance with an area under the curve of 0.79. Other good performers with similar AUC scores were logistic regression, nearest neighbor, and support vector machine classifiers. The worst results were obtained with Gaussian process and quadratic discriminant analysis. The feature selection outcome pointed to functional connections between visual, sensorimotor, executive control, reward, and salience networks as the most relevant for classification. We conclude that AUD can be identified using machine learning classifiers in the absence of nicotine comorbidity. (shrink)

En esta investigación se busca analizar, a través de un texto fundamental de la obra Ciencia de la Lógica de Hegel, que versa sobre la línea nodal de relaciones de medida, un modo distinto tanto de hacer filosofía como de comprender la relación que se da entre la naturaleza y el espíritu.

No es posible seguir pensando a Zubiri desde su gran libro "Sobre la esencia" sin tener en cuenta la inmensa obra que levantó al final de su vida: "Inteligencia sentiente". Desde esta última obra, el filósofo español nos muestra la Noología y desde ella podemos ver no solamente las grandes posibilidades que nos ofrece el pensamiento último de Zubiri para resolver grandes problemas que las filosofías del siglo XX intentaron resolver, sino también para tomar distancia total de la Fenomenología de (...) Husserl y de las filosofías que nacieron de ella. Este artículo busca introducirse en esas cuestiones y señalar cómo la Fenomenología fue un espejismo necesario para el siglo pasado y cómo Zubiri desde ella y contra ella fue constituyendo su propia obra de madurez.

Lo que se pretende con este artículo es pensar el Ereignis de Heidegger a la luz del problema del Sein en un triple referente; el cual se muestra en tres palabras fundamentales: Wink, Aufriss y Destruktion. Esto nos llevará a estudiar someramente a nuestro autor desde los cursos de los años veinte anteriores a Sein und Zeit hasta el Seminario de Le Thor de 1969. Pero todo este horizonte de pensamiento estará articulado desde los Beiträge zur Philosophie. Vom Ereignis (1936-38).

En este texto analizaremos el decir filosófico zubiriano con el que pretende expresar la realidad de modo pleno y adecuado. En esto nos daremos cuenta de un grave y radical problema: la lengua que le ha sido dada social e históricamente al filósofo, la lengua en la que vive y se mueve intelectivamente y la lengua en la que quiere expresarse filosóficamente no coinciden en nada. La primera, la lengua vivencial, es una lengua románica y, por tanto, hunde sus raíces (...) en el indoeuropeo; en cambio, la segunda, la lengua filosófica, está incardinada desde la estructura lingüística semítica. ¿Por qué Zubiri busca acusar con tanto afán la realidad de un modo semítico y no lo hace en el indoeuropeo que habla y piensa? Aquí radica toda la cuestión fundamental que debemos analizar. A pesar de todas las dificultades que traerá para el desarrollo, claridad y divulgación del pensamiento zubiriano, se prefiere insistir rotundamente en el uso de la estructura semítica para expresar la realidad). Esta postura radical del pensador no es un mero capricho, sino una necesidad que se le impone (por lo menos, así lo piensa él). Y se le impone en y por la realidad misma que aprehende sentientemente. A raíz de esto, pensamos que Zubiri puede ser considerado como un pensador posmoderno". (shrink)

Attention is often conceived as a gateway to consciousness . Although endogenous spatial attention may be independent of conscious perception , exogenous spatial orienting seems instead to be an important modulator of CP . Here, we investigate the role of auditory alerting in CP in normal observers. We used a behavioral task in which phasic alerting tones were presented either at unpredictable or at predictable time intervals prior to the occurrence of a near-threshold visual target. We find, for the first (...) time in neurologically intact observers, that phasic alertness increases CP, both objectively and subjectively. This result is consistent with evidence showing that phasic alerting can ameliorate the spatial bias exhibited by visual neglect patients . The alerting network may increase the activity of fronto-parietal networks involved in top-down amplification required to bring a stimulus into consciousness. (shrink)

Husserl comenzó oponiéndose a la posibilidad de considerar el yo como centro de referencia esencial de los actos intencionales. Sin embargo, luego aceptó incluirlo en la descripción fenomenológica como centro de referencia de las vivencias intencionales. Se analizan esos dos momentos y se estudia su posible correlación con la teoría kantiana del yo, para hacer énfasis, finalmente, en una importante diferencia entre ambos autores.

The reinforcement sensitivity theory proposes that neurobiological systems mediate protective and appetitive behaviours and the functioning of these systems is associated to personality traits. In this manner, the RST is a link between neuroscience, behaviour, and personality. The theory evolved to the present revised version describing three systems: fight-flight-freezing, behavioural approach/activation, and behavioural inhibition. However, the most widely available measure of the theory, the BIS/BAS scales, only investigates two systems. Using a large longitudinal community survey, we found that the BIS/BAS (...) scales can be re-structured to investigate the three systems of the theory with a BIS scale, three BAS scales, and a separate fight-flight-freezing system scale. The re-structured scales were age, sex, and longitudinally invariant, and associations with personality and mental health measures followed theoretical expectations and previously published associations. The proposed framework can be used to investigate behavioural choices influencing physical and mental health and bridge historical with contemporary research. (shrink)

El presente artículo busca dar con la influencia de Baruch Spinoza en el pensamiento de Xavier Zubiri en torno al tema de la materia y de allí entender lo que es lo estético. Es sabido que Zubiri desde joven fue un gran lector de Spinoza; incluso lo enseñaba en detalle a su amiga-estudiante María Zambrano. Y lo que pensamos es que Zubiri siempre estuvo influenciado por el pensador holandés y esto se ve reflejado en cómo Zubiri trata su concepto de (...) materia, clave en su obra; y tal concepto nos permite, por ejemplo, entender lo estético en el pensador español.

RESUMENEste artículo es un intento de pensar lo que es el cuerpo a la luz de las filosofías de Gilles Deleuze y de Xavier Zubiri. Ambos pensadores han sido muy radicales en sus posiciones respecto al papel del sentir. A veces es más conocido, para algunos, el pensamiento deleuziano en torno al cuerpo y las sensaciones, pero la reflexión zubiriana es también una filosofía del cuerpo que a veces no ha sido atendida en su profundidad. Además, vemos que ambos pensadores (...) tienen muchos puntos en común; uno de ellos es el denominado «Cuerpo sin órganos». Desde esta categoría deleuziana se indicará la proximidad con la filosofía zubiriana y con ello la importancia que cobra el cuerpo en una filosofía para los tiempos actuales.PALABRAS CLAVEDELEUZE, ZUBIRI, LÓGICA, IMPRESIÓN, SENSACIÓN, CUERPO SIN ÓRGANOS, INTELIGENCIA SENTIENTE.ABSTRACTThis article attempts to think what the body is from the perspective of the philosophy of Gilles Deleuze and also from Xavier Zubiri. Both thinkers have been totally radicals in their positions concerning the role of sensations. It may sound more natural, for some, to associate Deleuze’s thought on body and sensations than that of Zubiri; but we have to acknowledge that the latter’s thought is also a philosophy of the body and, therefore, we shall attend it in its whole depth. Moreover, we have to recognize that both thinkers have lots of common points, one of them the so-called «Body without organs». From this deleuzian category will be indicated the proximity between deleuzian and zubirian philosophy; and with that the importance that acquires the body in a philosophy worth of our times.KEY WORDSDELEUZE, ZUBIRI, LOGIC, IMPRESSION, SENSATION, BODY WITHOUT ORGANS, SENTIENT INTELLIGENCE.

Human nature is a puzzling matter that must be analysed through a holistic lens. In this commentary, I foray into anthropology's biosocial dimensions to underscore that human relations span from microorganisms to global commodities. I argue that the future of social-cultural anthropology depends on the integration of evolutionary theory for its advancement. Ultimately, since the likelihood of novel zoonoses' emergence, digital ethnography could offer remarkable opportunities for ethical and responsible inquiries.

Indecent Theology has provided both Feminist Theology and Liberation Theology with new contours for rethinking bodies, power, dominance, and submission. With regard to the logic of dominance that radically pushes the margins of the margins into a form of inexistent living, I suggest a material turn to rethink the contours that are evoked with Indecent Theology. Materialism has long stood as a philosophy opposing the overwhelming dominance of language and the poststructuralist emphasis that has emerged as the ‘linguistic turn’. Considering (...) ‘new materialism’ as a theoretical platform to reread Indecent Theology provides theologies and ethics an opportunity to re-imagine indecent methodologies through indecency, a sort of ethical perversion. I suggest an indecent turn in mobilizing materialism and kink as theories to reread indecent theology for a productive queer materialist sexual theology. The feminist liberation theology of Marcella Althaus-Reid pushes both feminism and liberation into new contours of power and submission and initiates new contours of queer sexuality into the discourse. When analysing Althaus-Reid’s work, we are brought to attention to the margins of the margins, an awareness of the struggle for power and control by those deemed less than. There are contours of power at and in the margins of the margins, those who occupy ‘bottom space’. From a kink/bdsm orientation, I propose to reread Alrhaus-Read’s feminist liberation theology as decolonial erotics that helps to generate a productive materialist queer sexuality. The overarching methodology of this article is a quasi-auto ethnographic investigation into the ways in which the contours of race, class, gender, sex, sexuality, and ability affect power and submission and in turn reframes both queer theology and queer sexuality that is rooted in the living out of a very particular theology and ethics, which is rooted in queer relating. Theology can neither materialize in a vacuum nor in isolation. An indecent turn to a queer sexual theology that is rooted in a queer relationality demands attention to the interdependence of queer relating that is materialized through the interdependency of the growing queer desires of bodies, power, dominance, and submission.

The aim of this research is to propose a framework to remedy potential dignity violations to families with children with disabilities seeking tourism experiences. We build on a systematic literature review on the topic of tourism of families with children with disabilities to propose a conceptual framework of dignity protection for this segment. This framework analyzes the responsibilities of four stakeholders (service providers, government, other tourists, and families) classified into dignity thresholds, to reduce attitudinal, information, and infrastructure barriers faced by (...) children with disabilities and their families when traveling. This paper is one of the few studies that connects the concept of dignity to the family tourism literature (with a special focus on a type of family variation neglected in terms of adequate tourism experiences) through a stakeholder approach focusing on the collaboration among actors within the industry to advance the creation of suitable tourism experiences for families with children with disabilities.

En este texto se analiza la importancia de la construcción o el fortalecimiento de la autoridad y confianza epistémicas desde la perspectiva de primera persona de las mujeres y cómo estas cualidades se pueden explorar en su íntima conexión con la confianza corporizada. Las mujeres, a través de sus experiencias particulares de sí mismas, del mundo y de los otros, asimilan de manera perjudicial la desconfianza epistémica que su comunidad de conocimiento les transmite. Se desarrolla esta tesis con base en (...) la concepción fenomenológica de cuerpo vivido, tal como fue planteada por Merleau-Ponty, pero con un énfasis en los trabajos de Simone de Beauvoir e Iris Young, pues son estos los que permiten comprender cómo las estructuras fundamentales de la experiencia y los modos de ser corporizados de las mujeres recorren una ruta experiencial diferente a la de los hombres en razón del tipo de sociedad en que se encuentran. En la parte final del texto se propone una manera de reconstruir o fortalecer la confianza y autoridad epistémicas de las mujeres a partir de una ruta de autoconocimiento corporizado y del cambio de hábitos.

Cultural landscapes represent a complex category where the nature-culture dichotomy seem to not be able to unfold the main features and the profound relations that humans have with the environment. Drawing on ethnographic data collected in the saltpans of Se-ovlje (Slovene Istria) and Janubio (Lanzarote--Canary Islands) this article examines informant`s perceptions about the awareness of the importance and the enhancement of the holistic values of both saltpans, as well as the impacts and benefits of tourism. Comparing these perceptions about both (...) cultural landscapes, I try to suggest that the complex fruitfully relations between humans and nature in these saltpans are at odds with the neoliberal logic of nature which exploit and commoditize its resources depriving them of their respective agency. A sustainability to contrast the harmful activities of the market ought to be understood not as a simply isolation and fencing of nature for the sake of conservation, but as a preservation that need to foster the continuity of the deep interactions between human culture and non-human nature which are the core of the cultural landscapes.

Emotional self-regulation in childhood and adolescence constitutes a growing interest in the scientific community, highlighting in recent years the need to observe its development in their daily life. Therefore, the objective of this systematic review is to characterize publications referring to the development of emotional self-regulation of people under 18 years-old, in natural contexts. Based on the PRISMA guidelines, searches are carried out in the Web of Science, Scopus and PsycINFO databases, and in Google Scholar until May 2020. After reviewing (...) the full text of 376 publications, 14 works are selected that are observed in their extrinsic, substantive and methodological characteristics based on the GREOM and MQCOM guidelines, by two independent evaluators. Most of the studies correspond to the last 20 years, increasing the interest in observing older children, in interaction with adults and/or in different cultures. They apply mixed methodologies, not always ascribing to a low intensity design. Strengths are observed regarding the collection and analysis of the quality of the data; and weaknesses related to the failure to record the duration and sequence of behaviors, highlighting the use of guidelines as guides for future research.

RESUMEN En este artículo se plantea una discusión con el enfoque doxástico de los delirios. A pesar de que esta línea de análisis ha hecho importantes aportes a la comprensión del fenómeno, tiene dificultades importantes a la hora de aportar un marco explicativo completo de los delirios, porque deja por fuera el aspecto total de la experiencia y sigue basándose implícitamente en la idea de que podemos estudiar de manera separada e independiente los aspectos físicos, cognitivos y experienciales de un (...) fenómeno tan complejo. El artículo propone que, más allá de la decisión acerca de si se debe considerar a los delirios como creencias irracionales o no, o de si se puede concebirlos como creencias en absoluto, es necesario tener en cuenta la drástica transformación del mundo entero de la experiencia que se da en el sujeto delirante, tal como lo plantea la fenomenología. ABSTRACT This article discusses the doxastic approach to delusions. Although this analytic approach has made important contributions to our understanding of the phenomenon, it faces serious difficulties when it comes to providing a complete explanatory framework of delusions, as it leaves out the experiential aspect. This analytic approach continues to be implicitly based on the idea that the physical, cognitive and experiential aspects of such a complex phenomenon can be studied separately. The article suggests that, in addition to merely considering whether or not delusions ought to be taken as irrational beliefs, or even as beliefs at all, it is necessary to take into account the drastic transformation of the entire experiential world of the delusional subject, as suggested by the phenomenological approach.

Se examina la relación entre razones y causas de la acción en el psicoanálisis freudiano. Hay acuerdo en que Freud confundía, o por lo menos no hizo una distinción rigurosa a lo largo de su trabajo, entre razones y causas. Se analizarán dos interpretaciones al respecto. De un lado, la que sostiene que había en él una tendencia naturalista y que, en ese sentido, nunca abandonó su pretensión de encontrar las causas de la acción humana; de otro lado, la que (...) defiende que en Freud imperó siempre una orientación más psicologizante, con base en la cual defendió la búsqueda del sentido de actos fallidos, sueños, etc.; lo cual lo llevó a abandonar su orientación cientificista y a concentrarse en la comprensión o interpretación de la acción. Como alternativa se propone considerar que el conflicto en Freud se soluciona si dejamos de lado los dualismos razones / causas y comprensión /explicación. This paper examines the relationship between reasons and causes of action in Freudian psychoanalysis. There is an agreement on the issue that, throughout his work, Freud confused or at least did not make a rigorous distinction between reasons and causes. Two interpretations will be analyzed on this matter. On one hand, a position that holds that there was a naturalistic tendency in Freud and, in that sense, that he never abandoned his aspiration to find the causes of human action. On the other hand, a position that argues that a psychologizing orientation always prevailed in Freud, based on which he defended the search for the meaning of Freudian slips, dreams, etc; which led him to abandon his scientific orientation and to focus on understanding or interpreting the action. As an alternative it is suggested that the conflict in Freud is solved if we discard the dualisms reasons/causes and understanding/explanation. (shrink)

In this article, I present the structural consequences generated by the continuous and systematic epistemic injustices carried out in certain communities or institutions. These injustices contribute to building a structure of silencing, denial of epistemic authority, cover-up and impunity. The importance of the normative aspect that guides the reflections about these injustices will be exposed in two senses: on the one hand, insofar as it is necessary to have criteria that allow establishing the truth in the background of evaluation of (...) epistemic injustices and, on the other, in the sense of specifying how systematically attempting against it produces almost irreversible epistemic damage and guarantees the perpetuation of the structure. It will be shown how this happens within the framework of a powerful institution such as the Catholic Church, which has exhibited a pattern of testimonial injustices and the cover-up of abuses within it for decades.

Extensive research has demonstrated that rs1360780, a common single nucleotide polymorphism within the FKBP5 gene, interacts with early-life stress in predicting psychopathology. Previous results suggest that carriers of the TT genotype of rs1360780 who were exposed to child abuse show differences in structure and functional activation of emotion-processing brain areas belonging to the salience network. Extending these findings on intermediate phenotypes of psychopathology, we examined if the interaction between rs1360780 and child abuse predicts resting-state functional connectivity (rsFC) between the amygdala (...) and other areas of the salience network. We analyzed data of young European adults from the general population (N = 774; mean age = 18.76 years) who took part in the IMAGEN study. In the absence of main effects of genotype and abuse, a significant interaction effect was observed for rsFC between the right centromedial amygdala and right posterior insula (p <.025, FWE-corrected), which was driven by stronger rsFC in TT allele carriers with a history of abuse. Our results suggest that the TT genotype of rs1360780 may render individuals with a history of abuse more vulnerable to functional changes in communication between brain areas processing emotions and bodily sensations, which could underlie or increase the risk for psychopathology.

Introducción: Se presenta un análisis cualitativo del acompañamiento psicosocial a jóvenes en condiciones de vulnerabilidad desde la ecología humana durante 12 meses entre 2010 a 2011; utilizando técnicas pedagógicas evaluativas participativas. Éstas, son una alternativa para crear espacios reflexivos con el propósito de potenciar la resiliencia en las relaciones comunicativas y formar en el respeto. Objetivo: Generar bienestar, prevenir la farmacodependencia y contribuir a la promoción de la salud. Material y Métodos: Se revisaron los antecedentes temáticos, fueron seleccionados 100 estudiantes (...) entre 11 y 19 años de dos instituciones educativas públicas en condiciones vulnerables;se desarrollaron cuatro talleres reflexivos y cuatro prácticas lúdicas y se realizaron tres grupos focales con estudiantes, profesores y padres de familia. Resultados y Discusión: El contexto social de la población intervenida, revela problemas de abuso sexual, violencia intrafamiliar y eventos violentos en el vecindario por grupos armados ilegales, entre otros, que constituyen factores de riesgo importantes para la farmacodependencia. Conclusión: Se infiere que lo psicosocial incide en la farmacodependencia, afectando la convivencia de la población estudiada por múltiples causas del orden psicoafectivo, sociocultural, económico y político que van desde el consumo cultural hasta la seguridad alimentaria. Introduction: A qualitative analysis of the psycho-social support to young people in situations of vulnerability from human ecology is presented for 12 months between 2010 to 2011; using participatory evaluative pedagogical techniques. These are an alternative to create reflective spaces with the purpose of enhancing resilience in communicative relationships and working in respect. Objective: to generate well-being, prevent drug abuse and contribute to the health promotion. Material aids and methods: the thematic background was reviewed, 100 students between 11 and 19 years of two public schools in vulnerable conditionswere selected; four reflective workshops and four playful practices were developed and three focus groups with students, teachers and parentswere conducted. Results and discussion: the social context of the manipulated population reveals sexual abuse problems, domestic violence and violent events in the neighborhood by illegal armed groups, among others, which constitutemajor risk factors for drug abuse. Conclusion: It can be inferred that the psychosocial factors impact on drug dependence, affecting the coexistence of the population studied by multiple causes of the psychological, socio-cultural, economic and political order, ranging from cultural consumption to food security.

Recientes innovaciones en la teoría social están abocadas a desarrollar puntos de encuentro y colaboración con la teoría de la complejidad. Por supuesto, tal aproximación conlleva una reconceptualizacion profunda de la noción de sistema y de diversas dinámicas y procesos asociados.

The small-improvement argument is usually considered the most powerful argument against comparability, viz the view that for any two alternatives an agent is rationally required either to prefer one of the alternatives to the other or to be indifferent between them. We argue that while there might be reasons to believe each of the premises in the small-improvement argument, there is a conflict between these reasons. As a result, the reasons do not provide support for believing the conjunction of the (...) premises. Without support for the conjunction of the premises, the small-improvement argument for incomparability fails. (shrink)

We introduce a novel experimental paradigm for eliciting metaphoric expressions in spontaneous speech, under controlled conditions. Participants were presented with a pair of words on a PC monitor and were asked to provide a verbal response describing a conceptual relation between the stimuli. The proportion of metaphoric responses depended on the stimuli in a predictable manner. A large proportion of metaphoric responses was obtained for stimuli that were derived from existing metaphors. The chronometric study of metaphor production in this paradigm (...) produced 3 major findings: (a) a figurative-literal difference: responses that included metaphorical expressions showed greater reaction times (RTs) than responses with only literal expressions; (b) familiarity effect: responses that included more-familiar metaphorical expressions showed smaller RTs than responses that included less-familiar metaphorical expressions; (c) degree of metaphoricity effect: responses that included highly metaphorical expressions showed greater RTs than responses that included less metaphorical expressions. We discuss the processing implications of these results. (shrink)

Una vez (...) aclarado estos distintos puntos podremos comprender la oculta pero significativa función del mito de los metales en la constitución del orden social platónico. ABSTRACT:This article attempts an interpretation of the account of the myth of the metals as expounded by Plato in the Politeia. We address the following question: How is the social order established in the Platonic polis? To answer this question we must clarify: i) the role of education in the constitution of the social order; ii) the correlation between the myth of the metals and the social order; iii) the tripartite constitution of the human psyche. Once these various points have been made clear, we can understand the hidden but significant function of the myth of the metals in the constitution of the Platonic social order. (shrink)
