Resumen: El presente artículo constituye un aporte al conocimiento del arte en su vinculación con la filosofía y el psicoanálisis, en tanto aborda la tensión entre la representación y la construcción simbólica de la imagen artística en el contexto cultural/estético contemporáneo, mediante la relación entre lo Real lacaniano y la estática negativa de Adorno. Dicha relación encuentra su punto de articulación en el fenómeno estético de lo Bello, entendido como lo que encara al sujeto con el vacío de su deseo (...) radical, sin engañarlo y que permite integrar la negatividad propia de lo Real con los elementos formales que componen la obra artística, así como con los conceptos de radicalidad y autenticidad de la propuesta adorniana. La articulación entre la estética negativa de Adorno y el efecto estético de lo Bello de Lacan, se ejemplifica con una interpretación en clave psicoanalítica de la obra de la artista colombiana Doris Salcedo. Abstract: This article constitutes a contribution to the knowledge of art in its connection with philosophy and psychoanalysis, as it approaches to the tension between the representation and the symbolic construction of the artistic image in the contemporary cultural / aesthetic context, through the relationship between the Lacanian Real and Adorno's negative aesthetic. This relationship finds its articulation point in the aesthetic phenomenon of the Beautiful, understood as what confronts the subject with the emptiness of its radical desire, without deceiving it and that allows to integrate the Real´s negativity with the formal elements that make up the artistic work, as well as the Adornian proposal concepts of radicality and authenticity. At the end, a psychoanalytic interpretation of colombian artist Doris Salcedo’s work is made, in which the negative aesthetics and the aesthetic effect of the Beautiful are integrated. (shrink)

Se propone una reflexión sobre el método clínico y sus etapas, la relación médico-paciente y la presencia tecnológica en la Cardiología Pediátrica. La ecocardiografía transtorácica no puede sustituir el pensamiento médico, la anamnesis, ni el examen físico. Como medio diagnóstico realizado e interpretado por humanos, está sujeto a error, el cual se minimiza según la calidad de los datos clínicos aportados por el médico que lo solicita. El presente trabajo tiene como objetivo analizar los aspectos éticos del método clínico en (...) relación con la utilización de la ecocardiografía transtorácica en niños con cardiopatías congénitas. It is proposed a reflexion about the clinical method and its stages, the doctor-patient relation and the presence of technology in paediatric cardiology. The transthoracic echocardiography can4t substitute medical thought, neither the anamnesis nor the physical examination. As a diagnostic medium carried out and interpreted by humans, it is subject to error, which it is minimized according to the quality of the clinical data provided by the doctor who requests them. The present work has the objective to analyse the Ethical foundations of the clinical method in connection with the use of transthoracic echocardiography in children with congenital cardiopathies.

Seen from the point of view of evaluation conditions, a usual way to obtain a connexive logic is to take a well-known negation, for example, Boolean negation or de Morgan negation, and then assign special properties to the conditional to validate Aristotle’s and Boethius’ Theses. Nonetheless, another theoretical possibility is to have the extensional or the material conditional and then assign special properties to the negation to validate the theses. In this paper we examine that possibility, not sufficiently explored in (...) the connexive literature yet.We offer a characterization of connexive negation disentangled from the cancellation account of negation, a previous attempt to define connexivity on top of a distinctive negation. We also discuss an ancient view on connexive logics, according to which a valid implication is one where the negation of the consequent is incompatible with the antecedent, and discuss the role of our idea of connexive negation for this kind of view.

BackgroundSevere brain injury is a leading cause of death and disability. Diagnosis and prognostication are difficult, and errors occur often. Novel neuroimaging methods can improve diagnostic and prognostic accuracy, especially in patients with prolonged disorders of consciousness (PDoC). Yet it is currently unknown how family caregivers understand this information, raising ethical concerns that disclosure of neuroimaging results could result in therapeutic misconception or false hope.MethodsTo examine these ethical concerns, we conducted semi-structured interviews with caregivers of patients with PDoC who were (...) enrolled in a concurrent neuroimaging research program designed to detect covert consciousness following severe brain injury. Caregivers held surrogate decision-making status for a patient. Interviews were conducted at two time points for each caregiver. The first interview occurred before the disclosure of neuroimaging results. The second occurred after disclosure. Descriptive analysis was applied to the data of four interview topics: (1) expectations for neuroimaging; (2) reactions to evidence of preserved cognition; (3) reactions to null results; and (4) understanding of the results and study.ResultsTwelve caregivers participated in the study; two caregivers shared surrogate decision-making status for one patient with PDoC. Twenty-one interviews were completed; one caregiver declined to participate in the post-disclosure interview. Three patients with PDoC associated with the study displayed evidence of covert consciousness. Overall, caregivers understood the neuroimaging research and results. Caregivers who received results of covert consciousness were generally pleased. However, there was some variation in expectations and reactions to these data and null results.ConclusionThis study, for the first time, reveals caregiver expectations for and reactions to neuroimaging evidence of covert consciousness in patients with PDoC. Caregivers understood the neuroimaging research and results, casting doubt on speculative ethical concerns regarding therapeutic misconception and false hope. However, disclosure of neuroimaging result could be improved. Pre-disclosure consultations might assist professionals in shaping caregiver expectations. Standardization of disclosure might also improve comprehension of the results. (shrink)

Work stress is consistently linked with the deterioration of cognitive and mental health, limitations in everyday workplace performance, and an increased risk of developing diseases. A common thread binding these consequences appears to be stress-associated alterations in neuropsychological functions and affective domains, especially those reliant on hippocampal, prefrontal, and amygdala brain area. Although research broadly supports the claim that the practice of mindfulness meditation for the reduction of the consequences of stress and the promotion of health exert positive effects on (...) workplaces, the precise neuropsychological benefits of Mindfulness-based interventions in the context of organizations remain elusive. In this review, we will analyze the impairments imposed by stress on the brain areas and functions and the benefits of MBIs from a neuropsychological point of view. This is significant since there is a centrality of cognitive functions in core processes necessary for work achievements, such as emotion regulation, problem-solving, and learning. The promotion of wellbeing is a responsibility shared between workers and organizations. Developing healthy environments allows workers to exercise greater control over their work, face work challenges, work productively and develop their talent. (shrink)

Abstract. The notion of similarity has been studied in many areas of Computer Science; in a general sense, this concept is defined to provide a measure of the semantic equivalence between two pieces of knowledge, expressing how “close” their meaning can be regarded. In this work, we study similarity as a tool useful to improve the representation of arguments, the interpretation of the relations between arguments, and the semantic evaluation associated with the arguments in the argumentative process. In this direction, (...) we present a novel mechanism to determine the similarity between two arguments based on descriptors representing particular aspects associated with these arguments. This mechanism involves a comparison process influenced by the context in which the process develops, where this context provides the relevant aspects that need to be analyzed in the application domain. Then, we use this similarity measure as a quantity to compute the result of attacks and supports in the argumentation process. These valuations, applied to a Bipolar Argumentation Frameworks, allowed us to refine the argument relations, providing the tools to establish a family of new argumentation semantics that considers the similarity between arguments as a crucial part for the argumentation process.

El presente escrito tiene como propósito señalar algunas características de un nuevo tipo de razón que se basa en el pensamiento complejo y en sus principios: dialógico, hologramático y transdisciplinar, y su estrecha relación con el componente humano, el cual involucra la relación entre lo emocional y lo racional. Para lograrlo, el artículo está dividido en tres partes. La primera parte señala algunas limitaciones que ha tenido el paradigma científico moderno clásico, especialmente desde la desviación del concepto de la razón (...) gestado en la Ilustración; la segunda parte señala cómo, a su vez, la tendencia posmodernista no solo critica los alcances del proyecto moderno, sino que lanza una negación de los discursos basados en la ciencia y en la razón (ilustrada) e invita a las posturas relativistas extremas, y, en la tercera parte, se nombran algunas características que debe tener un nuevo tipo de razón basada en el pensamiento de Morin.

We present a novel argumentation-based method for finding and analyzing communities in social media on the Web, where a community is regarded as a set of supported opinions that might be in conflict. Based on their stance, we identify argumentative coalitions to define them; then, we apply a similarity-based evaluation method over the set of arguments in the coalition to determine the level of cohesion inherent to each community, classifying them appropriately. Introducing conflict points and attacks between coalitions based on (...) argumentative (dis)similarities to model the interaction between communities leads to considering a meta-argumentation framework where the set of coalitions plays the role of the set of arguments and where the attack relation between the coalitions is assigned a particular strength which is inherited from the arguments belonging to the coalition. Various semantics are introduced to consider attacks’ strength to particularize the effect of the new perspective. Finally, we analyze a case study where all the elements of the formal construction of the formalism are exercised. (shrink)

En este artículo discutimos la tesis de Jc Beall según la cual no hay negación lógica. Evaluamos la solidez del argumento con el que defiende su tesis y presentamos dos razones para rechazar una de sus premisas: que la negación tiene que ser excluyente o exhaustiva. La primera razón involucra una presentación alternativa de las reglas de la negación en sistemas de secuentes diferentes al que Beall presupone. La segunda razón establece que la negación no tiene que ser excluyente o (...) exhaustiva. (shrink)

Patient outcome after serious brain injury is highly variable. Following a period of coma, some patients recover while others progress into a vegetative state (unresponsive wakefulness syndrome) or minimally conscious state. In both cases, assessment is difficult and misdiagnosis may be as high as 43%. Recent advances in neuroimaging suggest a solution. Both functional magnetic resonance imaging and electroencephalography have been used to detect residual cognitive function in vegetative and minimally conscious patients. Neuroimaging may improve diagnosis and prognostication. These techniques (...) are beginning to be applied to comatose patients soon after injury. Evidence of preserved cognitive function may predict recovery, and this information would help families and health providers. Complex ethical issues arise due to the vulnerability of patients and families, difficulties interpreting negative results, restriction of communication to “yes” or “no” answers, and cost. We seek to investigate ethical issues in the use of neuroimaging in behaviorally nonresponsive patients who have suffered serious brain injury. The objectives of this research are to: (1) create an approach to capacity assessment using neuroimaging; (2) develop an ethics of welfare framework to guide considerations of quality of life; (3) explore the impact of neuroimaging on families; and, (4) analyze the ethics of the use of neuroimaging in comatose patients.

Methods: an observational, longitudinal descriptive and retrospective study is presented between June 2008 and June 2011 that consisted on observation to practical state exams and training at work, in the reference degrees; in addition, a survey was applied to patients to obtain information about the barriers that affect the communication process between technologists and patients. Results: there are communication inadequacies between the future professionals and patients. Conclusions: An insufficient mastery of the communication skills is demonstrated and therefore barriers that interfere with communication as the semantic and personal barriers. (shrink)

BackgroundFor a long time, in sports, researchers have tried to understand an expert by comparing them with novices, raising the doubts if the visual search characteristics distinguish experts from novices. Therefore, the aim of the present study was to review and conduct a meta-analysis to evaluate the differences in visual search behavior between experts and novices in team sports athletes.MethodsThis systematic review with meta-analysis followed the PRISMA 2020 and Cochrane's guidelines. Healthy team athletes were included, which engaged in regular practice, (...) from any sex or competitive level, specifically classified a priori as expert or novice in the original research. We considered only research published in peer-reviewed journals, with no limitations regarding date or language. It was considered healthy team sport athletes engaged in regular practice. The scenarios could be in situ or film-based. The databases of EBSCO, PubMed, Scopus, SPORTDiscus, and Web of Science were used to perform the searches. The risk of bias was calculated through the RoBANS tool.ResultsFrom a total of 6,257 records, of which 985 were duplicates, titles and abstracts of 5,272 were screened, and 45 required full-text analysis. Of those, 23 were excluded due to not fulfilling the eligibility criteria regarding participants. In the end, 22 studies were selected, however, as two studies were part of the same trial and were analyzed conjointly.DiscussionExperts showed to be older and with more years of practice. The ability to distinguish experts from novices was not so clear regarding the variables analyzed. This could be due to the strategies chosen in each study, which were specific to each scenario, and when grouping all together, it was lost information within non-representative averages. The distinction between experts and novices was not clear, showing a lot of heterogeneity in the included studies. The expert classification itself may have been the conditioning aspect for these results, retaining the doubt and the need for more studies in the field.Systematic review registrationThe protocol was pre-registered in OSF.

Huge losses and serious threats to ecosystems are common consequences of forest fires. This work describes a forest fire controller based on fuzzy logic and decision-making methods aiming at enhancing forest fire prevention, detection, and fighting systems. In the proposal, the environmental monitoring of several dynamic risk factors is performed with wireless sensor networks and analysed with the proposed fuzzy-based controller. With respect to this, meteorological variables, polluting gases and the oxygen level are measured in real time to estimate the (...) existence of forest fire risks in the short-term and to detect the recent occurrence of fire outbreaks over different forest areas. Besides, the Analytic Hierarchy Process method is used to determine the level of fire spread, and, when necessary, environmental alerts are sent by a Web service and received by a mobile application. For this purpose, integrity, confidentiality, and authenticity of environmental information and alerts are protected with implementations of Lamport’s authentication scheme, Diffie-Lamport signature, and AES-CBC block cipher.

The use of wireless sensor networks and the Internet of things to detect forest fire outbreaks may help to reduce the response time and avoid natural disasters. This work proposes the deployment of WSN to enhance the real-time monitoring of dynamic variables such as polluting gases, temperature or the presence of fire flames by infrared. In addition, the activation of forest fire alerts if environmental status may involve evidence of a recent fire outbreak. A fuzzy-based controller is implemented to manage (...) the uncertainty related to estimating forest fire occurrence and dynamic update of fuzzy sets is developed to distinguish usual and unusual environmental conditions of every monitored forest area. Merkle trees, AES and hash functions are considered to protect the integrity of environmental data. (shrink)

Se analiza la presencia intelectual de Ricardo Eduardo Latcham, ingeniero inglés, que llegado a Chile dio un mayor impulso al estudio tanto de la prehistoria latinoamericana como de la arqueología chilena, en los ámbitos del hábitat araucano y de las culturas del norte, en especial la atacameña. En este sentido, sus investigaciones prosiguieron a las de Uhle y posibilitaron integrar a los pueblos originarios del norte chileno al panorama de la prehistoria nacional. Latcham se adentró en registrar las conductas (...) de la sociedad chilena, tanto culta como popular, de fines del siglo XIX, legando agudas anotaciones etnográficas juntamente con una labor de tenaz divulgador de los progresos de la antropología europea, convirtiéndose en un corresponsal de las revistas británicas de la disciplina. Sus obras mayores las pudo difundir en el marco de sus actividades en el Museo de Historia Natural y en la Universidad de Chile. The intellectual presence of Ricardo E. Latcham, an English engineer whose arrival in Chile gave greater impulse to the study of Latin American pre-history and Chilean archaeology regarding araucano habitat and northern cultures, particularly the atacameno culture, is analyzed. His studies continued those of Uhle’s and made it possible to integrate the originary peoples of northern Chile to the panorama of the national pre-history. Latcham recorded the behaviors of both educated and popular Chilean society at the end of the 19th century, producing deep ethnographic records. He also conducted an enthusiastic dissemination of the progress made by European anthropology, becoming a correspondent of the British journals of this discipline. He disseminated his major works while working for the Museum of Natural History and the University of Chile. (shrink)
