Atrial fibrillation is the most common cardiac arrhythmia in clinical practice. It often starts with asymptomatic and short episodes, which are difficult to detect without the assistance of automatic monitoring tools. The vast majority of methods proposed for this purpose are based on quantifying the irregular ventricular response during the arrhythmia. However, although AF totally alters the atrial activity reflected on the electrocardiogram, replacing stable P-waves by chaotic and time-variant fibrillatory waves, this information has still not been explored for automated (...) screening of AF. Hence, a pioneering AF detector based on quantifying the variability over time of the AA morphological pattern is here proposed. Results from two public reference databases have proven that the proposed method outperforms current state-of-the-art algorithms, reporting accuracy higher than 90%. A less false positive rate in the presence of other arrhythmias different from AF was also noticed. Finally, the combination of this algorithm with the classical analysis of RR series variability also yielded a promising trade-off between AF accuracy and detection delay. Indeed, this combination provided similar accuracy than RR-based methods, but with a significantly shorter delay of 10 beats. (shrink)

We prove a number of results on the determinacy of σ-projective sets of reals, i.e., those belonging to the smallest pointclass containing the open sets and closed under complements, countable unions, and projections. We first prove the equivalence between σ-projective determinacy and the determinacy of certain classes of games of variable length <ω^2 (Theorem 2.4). We then give an elementary proof of the determinacy of σ-projective sets from optimal large-cardinal hypotheses (Theorem 4.4). Finally, we show how to generalize the proof (...) to obtain proofs of the determinacy of σ-projective games of a given countable length and of games with payoff in the smallest σ-algebra containing the projective sets, from corresponding assumptions (Theorem 5.1, Theorem 5.4).

La actual dificultad para sostener la existencia de una ley natural estriba fundamentalmente en que se niega la existencia de una esencia o bien la posibilidad de su conocimiento. A este respecto se analiza la posición de Tomás de Aquino, haciendo hincapié en su realismo, que lo hace afirmar que las esencias de las cosas nos son desconocidas. No obstante lo anterior, al analizar esta afirmación en el contexto de su obra, se puede colegir que eso no significa que no (...) sea posible conocer nada acerca de ella. (shrink)

Desde el punto de vista de los derechos humanos, el desplazamiento forzado no signif ica la violación puntual de un derecho, sino la vulneración múltiple, masiva y continua de muchos derechos fundamentales; fenómeno que ataca la titularidad de los derechos de la persona desplazada. Este ataque, en la mayoría de los casos, es provocado por el desplazador, y en algunas ocasiones por el Estado, siendo este, quien tiene la obligación primordial de prestar al desplazado la atención necesaria y de proporcionarle (...) una protección integral que frene la violación tanto de los derechos humanos, como del derecho humanitario, teniendo en cuenta siempre las diferentes aportaciones y elaboraciones que sobre el caso, proporcionan las organizaciones internacionales que trabajan al respecto.

El problema de la libertad es uno de los más áridos de la filosofía. Paul Ricoeur intenta reconstruir el problema tomando el eje del análisis: la naturaleza dicotómica de los discursos sostenidos sobre la cuestión. De un lado, tenemos la “perspectiva de la tercera persona”. Desde esta mirada, cada acto que realizamos está causalmente determinada. Por el otro lado, tenemos la “perspectiva de la tercera persona”, en la que todas nuestras acciones libres parecieran brotar del “yo”. El problema comienza cuando (...) intentamos reconciliar ambas perspectivas. Este trabajo revisará algunos de los argumentos presentados por ambos lados, y el posicionamiento de Ricoeur en el debate.

The consent process for publication of clinical images in medical journals varies widely. The extent of this variation is not known. It is also not known whether journals follow their own stated best practices or the guidance of the International Committee of Medical Journal Editors. We assessed consent requirements in a sample of 10 top impact factor general medicine journals that publish clinical images, examining variability in consent requirements for clinical image publication and congruence of requirements with the recommendations of (...) the ICMJE. Clinical image consent requirements varied widely from journal to journal. None of the studied journals, even amongst n = 4 ICMJE members or n = 8 journals who self-report adherence to ICMJE guidelines, comply with all of the recommendations of the ICMJE. Half of studied journals require a journal-specific consent form. Among top medical journals there is significant heterogeneity in consent requirements for clinical images. Variability of consent requirements is neither practical nor rational; inconsistent requirements create uncertainty for authors, present impediments to dissemination of scholarship, and undermine a shared professional understanding of how best to protect patient privacy. We propose adopting a standardized consent form and process for publication of identifiable images in medical journals, with uniform elements and explicit definitions. (shrink)

IntroductionThe 2019–2020 pandemic COVID-19 has become a global health crisis. While many recent studies on COVID-19 pandemic have focused on disease epidemiology and psychological status of patients, few have explored the multi-facet influential factors or combined perspectives from both the patients and healthcare workers. The purposes of this study were to: analyze the influencing factors of psychological distress of COVID-19 patients; and describe the experience of healthcare workers relieving psychological distress.Materials and MethodsThis study uses a mixed-method cross-sectional design, including a (...) quantitative study and a qualitative study, targeting two populations: COVID-19 patient and health workers, respectively. In the quantitative part, we recruited a convenience sample of patients with COVID-19 from five hospitals in Wuhan, Hubei Province from 10 to 15 April, 2020. Besides, we collected data by using participants’ socio-demographic information sheet, the Connor-Davidson Resilience Scale-10, the Herth Hope Index, the Distress Thermometer, the Revised Chinese Version of Mishel Uncertainty in Illness Scale, and the Chinese Version of Wake Forest Physician Trust Scale. In the qualitative part, the participants were healthcare workers involved in medical aid missions in Hubei Province, China. Meanwhile, we used sampling with convenient and purposive, data collection with a semi-structured online video interview, and text transcription with Colaizzi’s phenomenological method.ResultsThe results reveal that 25.7% of patients reported higher level of psychological distress. After controlling the sociodemographic variables, only severity of COVID-19 and uncertainty in illness shown significant effect on psychological distress in the regression model. The experience of healthcare workers emerged five themes: Particularly needed psychological care, Manifestation of negative emotion, Manifestation of proactive adaptation, Strategies relieving psychological distress, and gains of healthcare workers after delivering effective psychological care.ConclusionThe 25.7% of patients with COVID-19 still suffered from psychological distress, which should receive timely attention from healthcare workers. And the severity of the disease and disease uncertainty have a significant impact on distress. It is critical to train the healthcare workers on detecting the different manifestation of psychological distress, offering timely disease related information, and applying communication strategies.

The following study departs from the lecture, entitled “Creative thinking”, delivered by Claude Shannon in 1952 at the Bell Laboratories. This paper includes an interpretive and critical account of the necessary conditions, as well as the desirable procedures, which must be satisfied in the scientific and technological invention, within the frame of the so-called scientist’s spontaneous philosophy.

This study aimed to develop the Three-Dimensional Filial Piety Scale and explore its psychometric properties. Based on Wang’s Three-Dimensional Filial Piety Model, our study employed a review of the current literature, in-depth interviews, and feedback from experts and the target group. An initial 36-item scale using a bipolar Likert 6-point rating scale was developed. Then item analysis and exploratory factor analysis were conducted with sample 1 (n = 617) to explore the dimensions and final items, and a 15-item scale with (...) three factors was obtained. After that, confirmatory factor analysis was conducted to validate the 3-factor structure obtained through exploratory factor analysis with sample 2 (n = 585). Next, we tested criterion-related validity with sample 3 (n = 248) and test-retest reliability with sample 4 (n = 67). The results supported the model on which this scale was based and showed three dimensions of filial piety, namely the balance of interests, good affections, and family role norms. As a valid, reliable scale, the Three-Dimensional Filial Piety Scale can therefore be used in the Chinese context to measure filial piety for people of different genders, ages, and cohabitation situations.

Contemporary philosophy from Husserl focuses in the notion of world. Polo in his theory of knowledge explain a notion of world that solves some latent difficulties in the speeches of Husserl and Heidegger.

Dentro de la labor polemista desarrollada por los cristianos orientales destaca el trasvase de todas las conceptualizaciones religiosas, las modalidades de argumentación y defensa del dogma, la elaboración del discurso y las técnicas de debate empleadas, el léxico adaptado y generado, la reescritura desarrollada a partir del material bíblico y la crítica coránica, así como las refutaciones de los planteamientos de los musulmanes, además del ingente caudal de información contenida en la propia polémica intracristiana. En la tipología polemista el elemento (...) por excelencia que va a caracterizar el saber compendiado en todos estos tratados es el teológico en sus distintas manifestaciones, que nos permite reconstruir la rica y compleja trama que configura el `saber teológico' tanto de las diversas iglesias orientales como de las distintas tendencias musulmanas. Las polémicas contribuyen, de este modo, a esclarecer los procesos que configuran la ideología de los distintos grupos humanos en conflicto. (shrink)

"Vocablo infaltable en todas las corrientes políticas occidentales, el republicanismo ha tendido a convertirse, en los últimos tiempos, es una suerte de significante vacío al que se apela sin más como sinónimo de justicia, de balance de poderes o de plena institucionalidad. En un libro que recupera el fundamental legado de Cicerón, Juan Acerbi presenta una serie de aspectos que se sumergen en las oscuras aguas de la tradición republicana para aclarar conceptos y aristas que, aún desde su latencia, (...) determinan muy de cerca el derrotero de las prácticas gubernamentales contemporáneas. Signado por el análisis de la performatividad del discurso político, de los usos de las justificaciones religiosas y de la íntima ligazón entre símbolos, formas de participación ciudadana, temporalidades y otros recursos para la conservación y ampliación del poder, este volumen recorre los meandros de la metapolítica para dejar al desnudo el cuerpo vivo del yo que sostiene a la república. Allí, el estudio sobre virtud del líder político, comprendido como un ser diferente del resto, demuestra que hace falta todavía sospechar de los vínculos entre un republicanismo cargado de razón pública y el capitalismo, que pretende que determinadas formas vacuas, exánimes, ocupen el lugar de los pensantes. A contrapelo de la desquiciada celebración de la inmediatez que se observa en nuestros días, Acerbi retoma un aspecto cardinal para cualquier pensamiento que pretenda ser político: la distinción entre lo necesario y lo contingente y la ubicación de toda acción política en el segundo de esos polos. De ese modo, apela a la palabra como forma fundamental de lo humano y logra ver, bajo un mismo cristal, eventos pasados, presentes y futuros que desenmascaran cualquier ilusión de una vida autoevidente."

The most documented juridical studies about hispanic woman in the late Middle Ages, belong to three specialities: political law, civil or common law (matrimonial), and criminal law. It is in the sphere of matrimonial law where the influence of christian principles has been described as prominent, contributing to the juridical conjugal parity, thus recognizing woman a full civil capability.

This paper constitutes my philosophy of teaching. I aim to model self-examination of teaching practice with the use of philosophical actionresearch. I use the method of triangulation and a mix of qualitative and quantitative data to validate and to strengthen my assertions. The analysis was grounded on empirical information, relevant current literature, and reflection. I argue that self-examination of practice is a worthy exercise for educators. When conducted systematically, self-examination efforts should not be regarded as merely subjective. It can be (...) harnessed as a tool to improve an educator's academic performance and personal wellbeing. It should rather be viewed as a basic or foundational discipline to sustain one's growth and love for teaching. The reflections on experience, insights, and the external validation one gathers in the process are worth the challenge. An examined life becomes worth living. (shrink)

Extending Aanderaa’s classical result that $\pi ^{1}_{1} < \sigma ^{1}_{1}$, we determine the order between any two patterns of iterated $\Sigma ^{1}_{1}$ - and $\Pi ^{1}_{1}$ -reflection on ordinals. We show that this order of linear reflection is a prewellordering of length $\omega ^{\omega }$. This requires considering the relationship between linear and some non-linear reflection patterns, such as $\sigma \wedge \pi $, the pattern of simultaneous $\Sigma ^{1}_{1}$ - and $\Pi ^{1}_{1}$ -reflection. The proofs involve linking the lengths of (...) $\alpha $ -recursive wellorderings to various forms of stability and reflection properties satisfied by ordinals $\alpha $ within standard and non-standard models of set theory.
