Partiendo de la comprensión de Heidegger en torno a los pensadores del inicio desplegada en los cuatros cursos de principios de los años cuarenta del siglo XX, querríamos mostrar la lectura de Heidegger de los pensadores del inicio en contraste con la de Gadamer en torno a los «presocráticos» mostrada en El inicio de la Filosofía occidental. Estudiaremos para ello la palabra Anfang en uno y otro autor contextualizando sus aproximaciones hermenéuticas a los textos griegos. Finalmente prestaremos atención a la (...) interpretación del poema de Parménides de Elea en El Inicio de la Filosofía occidental. Además de una diversa comprensión del final de la filosofía y la tarea del pensar, se nos irá revelando cómo Heidegger despliega indicaciones en torno a la articulación del pensar y la palabra en los pensadores del inicio, mientras Gadamer hace referencias al «valor poético» del poema de Parménides. Tras recorrer los diversos fragmentos transmitidos del poema, concluiremos señalando cómo la cuestión del ser y la verdad interpretada por Gadamer en Parménides remite a la pregunta por el carácter unitario —o al problema del continuo— de la presencia o aparecer que dice «ser», henologicamiente incomprensible sin atender a los cruces ἀλήθεια y φύσις.

Se van mostrar algunos contrastes en los lugares de la noción de mismidad del Poema de Parménides de Elea entre diversos textos de Martin Heidegger, con especial atención a qué tiene que ver el olvido de la «palabra enigma» de Parménides en Sein und Zeit con la noción de Sí mismo que allí se elabora. A través del camino hacia los “pensadores del inicio”, distinguir el horizonte de cuestionamiento del diálogo de Platón de aquel del Poema de Parménides, nos llevará (...) a su vez a señalar los diversos sentidos en que Heidegger piensa lo mismo en el Poema de Parménides.

Introductory words to Télos vol 18, nos. 1-2.

Robust theories concerning the connection between consciousness and brain function should derive not only from empirical evidence but also from a well grounded inind-body ontology. In the case of the comparator hypothesis, Gray develops his ideas relying extensively on empirical evidence, but he bounces irresolutely among logically incompatible metaphysical theses which, in turn, leads him to excessively skeptical conclusions concerning the naturalization of consciousness.

The architecture of brain, consciousness, and behavioral processes is shown to be formally similar in that all three may be conceived and depicted as Petri net patterned processes structured by a series of elements occurring or becoming active in stochastic succession, in parallel, with different rhythms of temporal iteration, and with a distinct qualitative manifestation in the spatiotemporal domain. A patterned process theory is derived from the isomorphic features of the models and contrasted with connectionist, dynamic system notions. This empirically (...) derived formulation is considered to be optimally compatible with the dual aspect theory in that the foundation of the diverse aspects would be a highly structured and dynamic process, the psychophysical neutral “ground” of mind and matter posed (but not properly determined) by dual aspect and neutral monist theories. It is methodologically sound to approach each one of these processes with specific tools and to establish concurrences in real time between them at the organismic level of analysis. Such intra‐level and inter‐perspective correlations could eventually constitute psychophysical bridge‐laws. A mature psychology of consciousness is necessary to situate and verify the bridges required by a genuine mind‐body science. (shrink)

Ha sido mi interés en los últimos años reflexionar formalmente sobre la conciencia en referencia a sus fundamentos y aspectos biológicos, en especial los cerebrales y los de comportamiento. Urdiendo sobre sus aspectos fisiológicos, fenomenológicos, epistemológicos y ontológicos, he explorado la naturaleza del dolor como un estado paradigmático de conciencia en un cuento de “neurociencia ficción” (Díaz, 2002), en un trabajo publicado en Salud Mental (Díaz, 2007) y en un libro sobre la conciencia viviente (Díaz, 2007). Estos (...) análisis utilizan al dolor como un fenómeno de conciencia fértil para examinar las principales conjeturas vigentes sobre la relación mente cuerpo y el problema epistemológico del acceso científico a la conciencia. La presente comunicación es un breve repaso de las principales ideas exploradas que se especifican en un decálogo de afirmaciones sobre la naturaleza y el conocimiento del dolor. Medical Epistemology: Ten Postulates on Pain It has been my interest in recent years to formally reflect on consciousness’s biological aspects and foundations, especially the brain-related and behavioral ones. In dwelling on its physiological, phenomenological, epistemological and ontological aspects, I have explored the nature of pain as a paradigmatic state of consciousness in a “neuroscience-fiction” tale (Díaz, 2002), in a work published in Mental Health (Díaz, 2007), and in a book on living consciousness (Díaz, 2007). These analyses use pain as a fertile consciousness phenomenon in order to examine the main current conjectures on the mind-body relation and the epistemological problem of scientific access to consciousness. This work is a brief summary of the main ideas explored, specified as a Decalogue of statements on the nature and knowledge of pain. (shrink)

Botanical preparations used by shamans in rituals for divination, prophecy, and ecstasy contain widely different psychoactive compounds, which are incorrectly classified under a single denomination such as “hallucinogens,” “psychedelics,” or “entheogens.” Based on extensive ethnopharmacological search, I proposed a psychopharmacological classification of magic plants in 1979. This paper re-evaluates this taxonomy in the context of consciousness research. Several groups of psychodysleptic magic plants are proposed: (1) hallucinogens—psilocybin mushrooms, mescaline cacti, dimethyltryptamine snuffs, and the synthetic ergoline lysergic acid diethylamide induce strong (...) perceptual changes, affective intensification, and cognitive enhancement. Their ethnobotanical uses include long lasting divination rituals, prophecy, and sacramental practice. (2) Trance-inducers—ergoline Convolvulaceae and South American Banisteriopsis produce quietness, abstraction, lethargy, mild sensorial and cognitive changes, and salient visual imagery changes used in trance rituals and specific divination practices. (3) Cognodysleptics—marijuana (tetrahydrocannabinol) and other terpene-containing plants induce changes in thought, imagination, and affective functions and are used in short-term divination or oneiromancy. (4) Deliriants—tropane-containing Solanaceae, wild tobacco, and Amanita muscaria (muscimol) induce a delirium characterized by dim and clouded consciousness, stupor, confusion, disorientation, perception distortion, difficulties in recollection, anxiety, irritability, excitation, and behavioral disorganization employed in sorcery, purification, or exorcism rituals. The core mental effects required for a drug to be used in shamanistic rituals include light-headedness, enhanced imagery, and experience intensification. This constellation was the reason why, in his classification of psychoactive compounds, the pioneer German psychopharmacologist Louis Lewin established in 1924 a group of drugs under the appropriate name of Phantastica.

Dual aspect theory has conceptual advantages over alternative mind-body notions, but difficulties of its own. The nature of the underlying psychophysical ground, for one, remains problematic either in terms of the principle of complementarity or if mind and matter are taken to be aspects of something like energy, movement, or information. Moreover, for a dual aspect theory to be plausible it should avoid the four perils of all mind-body theories: epiphenomenalism, reductionism, gross panpsychism, and the problems of emergence. An alternative (...) dual aspect theory, patterned process theory, is introduced and defended in neurological and individuality terms. The concept is grounded in a brain model of hierarchies wherein consciousness is conceived to be a cognitive aspect of the highest emergent brain inter-module activity, which is situated in the context of a living organism coping with a changing environment. The notion of individuals as psychophysical units unfolding as patterned processes is shown to constitute an integrative approach to brain, consciousness, and behavior that can avoid the conceptual perils and meet the ontological requirements of dual aspect reality and thereby advance the foundations of an integrative mind-body science.

Detecting intrusions in large networks is a highly demanding task. In order to reduce the computation demand of analysing every single packet travelling along one of such networks, some years ago flows were proposed as a way of summarizing traffic information. Very few research works have addressed intrusion detection in flows from a visualizations perspective. In order to bridge this gap, the present paper proposes the application of a novel projection method (Beta Hebbian Learning) under this framework. With the aim (...) to validate this method, 8 traffic segments, containing many flows, have been analysed by means of this projection method. The promising results obtained for these segments, extracted from the University of Twente dataset, validate the proposed application. (shrink)

The paper investigates how Catholic Social Teaching can contribute to the creation of fairer and more humane business models. It gives an outline of the main historical moments in the development of Catholic Social Teaching with regard to the economy and business management. Then it analyses the proposal of the Economy of Communion as a potential framework for companies that wish to implement Catholic Social Teaching in their activities. The EoC model suggests that company profits should be distributed in three (...) parts. The first part is dedicated to the company’s growth, development, and economic sustainability; the second toward the most needy people in the social environment of the organization; and the third part invested in education creating a new type of economic culture that is at the service of people and of the common good. The companies that belong to the EoC movement are for-profit businesses which consider reciprocity and gratuity an integral part of their businesses. Both reciprocity and gratuity are guided by the logic of the gift which is innate to human relations and should be promoted so businesses become more authentically human and favor the development of people.

This article analyzes Toole’s novel from a causal perspective, focusing on the cause-effect dynamics that make the plot advance, from the initial event at D.H. Holmes until the outcome in the Night of Joy. A combination of qualitative and quantitative methodologies has been applied to identify a series of 47 causal events that summarize all actions with an impact on plot development. Our research shows that the causal study of the novel is a useful approach that can reinforce or modify (...) qualitative assessments of previous studies. The relevance of “Night of Joy” plot within the whole narrative and its key role in the rest of the subplots are verified in numerical terms. Besides, we have expanded and quantified the causal chains operating in the novel; and we have made sure, as well, that every subplot is essential in order to reach the final outcome (with the only exception of Dr. Talc’s story). Finally, we have formulated an alternative outline of secondary plots than the ones supported by preceding research by using numeric metrics, demonstrating that “Paradise Vendors” and “Dorian Greene”, previously considered secondary storylines, exert a high impact on Confederacy’s finale, and are, perhaps, not so secondary plots after all.

Resumen: Diversos académicos han analizado la influencia de Toynbee y Spengler en la conocida saga Foundation, escrita por Isaac Asimov y considerada una de las más importantes de la ciencia ficción. Sin embargo, nuestra hipótesis es que, si bien existe un cierto diálogo transtextual con los trabajos de ambos autores, es en la obra del historiador griego Polibio, Historias, donde se halla la principal relación de tipo hipertextual. Comparando la anaciclosis descrita por Polibio con la evolución política que Asimov narra (...) en sus novelas, comprobamos que las semejanzas no solo alcanzan a los diferentes sistemas de gobierno, sino incluso a la misma secuencia en que estos se suceden. El resultado es una obra que permite una interesante lectura palimpséstica, enriqueciendo sensiblemente la experiencia del lector con formación humanística.: Several scholars have analyzed the influence of Toynbee and Spengler, in the well-known saga of the Foundation, written by Isaac Asimov and considered one of the most important of science fiction. However, although there exists a transtextual dialogue with Spengler's and Toynbee’s works, our hypothesis is that the main hypertextual relationship must be searched in the work of the Greek historian Polybius, Histories. Comparing the anacyclosis described by Polybius with the political evolution that Asimov narrates in his novels, we can see that similarities not only reach different systems of government, but even the very same sequence in which they happen. The result is a work that allows an interesting palimpsestic reading, significantly enriching the experience of those readers possessing humanistic knowledge. (shrink)

This paper aims to enhance security in IoT device networks through a visual tool that utilizes three projection techniques, including Beta Hebbian Learning (BHL), t-distributed Stochastic Neighbor Embedding (t-SNE) and ISOMAP, in order to facilitate the identification of network attacks by human experts. This work research begins with the creation of a testing environment with IoT devices and web clients, simulating attacks over Message Queuing Telemetry Transport (MQTT) for recording all relevant traffic information. The unsupervised algorithms chosen provide a set (...) of projections that enable human experts to visually identify most attacks in real-time, making it a powerful tool that can be implemented in IoT environments easily.

Surgical patient safety remains a concern worldwide as, despite World Health Organization recommendations and implementation of its Surgical Safety Checklist, adverse events continue to occur. The aim of this qualitative study was to explore the views and experiences of perioperative nurses regarding the factors that impact surgical patient safety. Data were collected through five focus groups involving a total of 50 perioperative nurses recruited from four public hospitals in Spain. Content analysis of the focus groups yielded four main themes: personal (...) qualities of the perioperative nurse, the surgical environment, safety culture, and perioperative nursing care plans. One of the main findings concerned barriers to the exercise of leadership by nurses, especially regarding completion of the Surgical Safety Checklist. Some of the key factors that impacted the ability of perioperative nurses to fulfil their duties and ensure patient safety were the stress associated with working in the operating room, time pressures, and ineffective communication in the multidisciplinary team. Targeting these aspects through training initiatives could contribute to the professional development of perioperative nurses and reduce the incidence of adverse events by enhancing the surgical safety culture.

ObjectiveThis study aimed to analyze the influence and measurement of the relationship and interaction between the elderly lifestyles after the appearance of the SARS-CoV-2 variant and the factors analyzed comprised life satisfaction levels, social relationships, and daily-life activities.MethodsThe study population was ≥ 65 in Castile-La Mancha. The research design was quantitative and arose from primary data collected via an ad hoc survey carried out through the Computer Assisted Telephone Interview system by randomly stratified sampling. The sample size was made up (...) of 1,065 cases, and the participants were selected through a random sampling stratified by gender quotas, age, province, and habitat size.ResultsThe results obtained revealed two main lifestyles, from which a notable behavioral change in personal relationships led to infer toward alternative lifestyles.ConclusionNotwithstanding the variation in lifestyles of the elderly after the pandemic, certain relationships remained unaltered. Thus, from the analyzed variables, relatives and friends relationships were scarcely influenced by the supervened incident. (shrink)

El presente artículo tiene como fin principal publicar la traducción de la lección de fray Luis de León del título, recientemente publicada y, como homenaje a este hecho, presentar la misma ofreciendo al lector el camino que la cuestión original planteada en la lección —con una trayectoria previa en Italia- recorre en el pensamiento español del XVII. Un camino que tiene dos grandes hitos: Cervantes y Spinoza. Cervantes, como se tratará de mostrar, desde una lectura directa del texto de (...) fray Luis, reflejada en su novela quijotesca _El curioso impertinente_. Spinoza, en cambio, más bien como filósofo impregnado de la cultura española y su pensamiento moral, del que se despega, como permite mostrar precisamente la reflexión anterior, al acoger el marco cartesiano de pensamiento ya en sus inicios, en el_ Tractatus de Intellectus Emendatione_.

Adaptive optics are techniques used for processing the spatial resolution of astronomical images taken from large ground-based telescopes. In this work, computational results are presented for a modified curvature sensor, the tomographic pupil image wavefront sensor, which measures the turbulence of the atmosphere, expressed in terms of an expansion over Zernike polynomials. Convolutional neural networks are presented as an alternative to the TPI-WFS reconstruction. This technique is a machine learning model of the family of artificial neural networks, which are widely (...) known for its performance as modeling and prediction technique in complex systems. Results obtained from the reconstruction of the networks are compared with the TPI-WFS reconstruction by estimating errors and optical measurements. The reconstructed wavefronts from both techniques are compared for wavefronts of 153 Zernike modes. For this case, a detailed comparison and grid search to find the most suitable neural network is performed, searching between multi-layer perceptron, CNN and recurrent networks topologies. In general, the best network was a CNN trained for TPI-WFS reconstruction, achieving better performance than the reconstruction software from TPI-WFS in most of the turbulent profiles, but the most significant improvements were found for higher turbulent profiles that have the lowest r0 values.

En la presente reseña reflexionaré sobre algunos aspectos de la obra de José Luis Díaz: Análisis de la conducta. Díaz plantea el problema mente-cuerpo como una relación donde lo mental no se entiende como algo absolutamente independiente del cuerpo. Así, admite una relación causal entre fenómenos mentales y físicos, sin por ello negar las particularidades de cada ámbito. En la reseña plantearé dos comentarios críticos a la teoría de José Luis Díaz. El primer (...) comentario concierne a la manera en que Díaz propone analizar y clasificar las relaciones que hay entre las distintas entidades psico-físicas. En el segundo comentario cuestionaré la versión que Díaz da sobre lo mental. De acuerdo con Díaz: “el evento mental es la manera como el sistema experimenta, desde adentro, el proceso de ciertos fenómenos multisinapticos...”. Argumentaré que esta caracterización de lo mental es más adecuada para las sensaciones. Añadiré que hace falta una caracterización de las conductas mentales que permita diferenciar entre conductas intencionales y no intencionales. Como mostraré en la reseña, pienso que la manera en que Díaz caracteriza las conductas no logra este cometido. Finalmente, añadiré una aclaración sobre la atribución e interpretación de las actitudes proposicionales. (shrink)

Este libro es un recorrido por los principales temas de la filosofía orteguiana al hilo de lo que fue el tema de su (nuestro) tiempo: la superación del idealismo. Un análisis textual pone de manifiesto el fracaso de esta superación, ya que aparecen un idealismo estético basado en a metáfora, ético, en el que sustituye la utopía del "deber ser" por el "tener que ser", gnoseológico, manteniendo el planteamiento dentro-fuera y, finalmente metafísico, donde el ser es caracterizado en términos de (...)
