IntroductionThe assessments of the motor symptoms in Parkinson’s disease are usually limited to clinical rating scales, and it depends on the clinician’s experience. This study aims to propose a machine learning technique algorithm using the variables from upper and lower limbs, to classify people with PD from healthy people, using data from a portable low-cost device. And can be used to support the diagnosis and follow-up of patients in developing countries and remote areas.MethodsWe used Kinect®eMotion system to capture the spatiotemporal (...) gait data from 30 patients with PD and 30 healthy age-matched controls in three walking trials. First, a correlation matrix was made using the variables of upper and lower limbs. After this, we applied a backward feature selection model using R and Python to determine the most relevant variables. Three further analyses were done using variables selected from backward feature selection model, movement disorders specialist, and all the variables from the dataset. We ran seven machine learning models for each model. Dataset was divided 80% for algorithm training and 20% for evaluation. Finally, a causal inference model using the DoWhy library was performed on Dataset B due to its accuracy and simplicity.ResultsThe Random Forest model is the most accurate for all three variable Datasets followed by the support vector machine. The CIM shows a relation between leg variables and the arms swing asymmetry and a proportional relationship between ASA and the diagnosis of PD with a robust estimator.ConclusionsMachine learning techniques based on objective measures using portable low-cost devices are useful and accurate to classify patients with Parkinson’s disease. This method can be used to evaluate patients remotely and help clinicians make decisions regarding follow-up and treatment. (shrink)

This paper has a double purpose: firstly, to assess the importance of seiðr magic rituals and of its practitioners within the social and mythological framework of Old norse-icelandic Literature. Secondly, by means of the analysis of certain scenes in The Saga of Gísli Súrsson, i aim to demonstrate that the inclusion of magic-religious motifs in the Sagas of icelanders has a triple objective: to provide a model to help understand apparently inexplicable phenomena, to intensify the tragic tone of the plot (...) and finally to depict those involved in the performance of seiðr in a very negative light.

El ser en su riqueza se expresa en el lenguaje que emana también del ser. El lenguaje emergió de su olvido en la filosofía griega, gracias a las ideas cristianas de encarnación y trinidad que le hicieron más justicia. El mayor milagro del lenguaje no estriba en que la palabra aparezca en su ser externo, sino en el hecho de que lo que emerge y se manifiesta sea siempre palabra. La vuelta de Gadamer al final de Verdad y método, en (...) torno a la evidencia de que el ser de lo bello consiste en presentarse, ilustra la estructura universal del ser mismo. Apalabrar a lo que es el ser mismo. Lo que determina y hace posible la interpretación es el presentarse del ser de lo que es. Being in its richness expresses itself in language, which itself emanates from Being. Language emerged from its oblivion in Greek philosophy thanks to the Christian ideas of incarnation and trinity, which did it more justice. Language's greatest miracle does not rest on the fact that the word appears in its external being, but on the fact that that which emerges and manifests itself is always word. Gadamer's turn at the end of Truth and Method, regarding the evidence according to which beauty's being consists of presenting itself, illustrates the universal structure of Being itself. Bespeaking what is Being itself. What determines and make possible interpretation is the presentation itself of the being of what is. (shrink)

Resumo: As apropriações de conceitos da teoria marxista por parte de teólogos da libertação podem ser consideradas incoerentes, seja pela histórica relação de condenação mútua entre marxistas e clérigos, seja pela distinção entre religião e economia-política, típica da modernidade. Diante disso, o conceito de afinidade eletiva de Weber, na interpretação do sociólogo franco-brasileiro Michael Löwy, possibilita renovar os estudos dos fenômenos sociais nos quais o marxismo e a teologia cristã parecem fundir-se em uma crítica social radical, como teologia da libertação. (...) Esse instrumental analítico permite identificar o sentido no qual algumas categorias marxistas são apropriadas, em forte confluência nos marcos do cristianismo de libertação. Para isso, em uma análise bibliográfica referenciada na obra de Löwy, apresenta-se o desenvolvimento do conceito de afinidade eletiva na tradição webero-marxista, identificando elementos dessa convergência na teologia do cristianismo de libertação. Por fim, buscam-se exemplos desses elementos em textos de diferentes expressões da teologia da libertação. Trata-se de um exercício teórico que almeja colaborar para a consolidação de uma abordagem específica do tema.: The appropriation of concepts of Marxist theory by liberation theologians can be considered incoherent, whether in terms of the historical relationship of mutual condemnation between Marxists and clerics, or in terms of the distinction between religion and political economy that is typical of modernity. However, Weber’s concept of elective affinity, in the interpretation of the Franco-Brazilian sociologist Michael Löwy, makes it possible to renew the studies of social phenomena in which Marxism and Christian theology seem to merge into a radical social critique, as in the case of liberation theology. This analytical approach enables us to identify the sense in which some Marxist categories are appropriated within the framework of liberation Christianity. In a bibliographical analysis that makes reference to Löwy’s work, we present the development of the concept of elective affinity in the Weberian-Marxist tradition and identify elements of its convergence with the theology of liberation Christianity. Finally, we look for examples of these elements in texts from different expressions of liberation theology. (shrink)

We study Hilbert spaces expanded with a unitary operator with a countable spectrum. We show that the theory of such a structure is ω -stable and admits quantifier elimination.

Why do we have social norms—of fairness, cooperation, trust, property, or gender? Modern-day Humeans, as I call them, believe these norms are best accounted for in cultural evolutionary terms, as adaptive solutions to recurrent problems of social interaction. In this paper, I discuss a challenge to this “Humean Program.” Social norms involve widespread behaviors, but also distinctive psychological attitudes and dispositions. According to the challenge, Humean accounts of norms leave their psychological side unexplained. They explain, say, why we share equally, (...) but not why we disapprove of those who don’t. I defend the Humean Program against this challenge. In particular, I suggest an idea for how to extend the Program to account for the psychological side of norms. Socially adaptive behaviors aren’t just likely to emerge in a group; They are also likely to be widely taught within it. The transmission of these behaviors through instruction explains why they are associated with distinctive normative attitudes and dispositions. These attitudes play a pedagogical role in helping transmit these behaviors to children and newcomers. (shrink)

We study the theory of a Hilbert space H as a module for a unital C*-algebra ${\mathcal{A}}$ from the point of view of continuous logic. We give an explicit axiomatization for this theory and describe the structure of all the representations which are elementary equivalent to it. Also, we show that this theory has quantifier elimination and we characterize the model companion of the incomplete theory of all non-degenerate representations of ${\mathcal{A}}$ . Finally, we show that there is an homeomorphism (...) between the space of types of norm less than 1 in this model companion, and the space of quasistates of the C*-algebra ${\mathcal{A}}$. (shrink)

En su libro Mind and World, John McDowell propone una caracterización de la percepción como un proceso cognitivo pasivo. En el presente texto quisiera mostrar que tal caracterización tiene un problema fundamental: implicaría que la percepción no tiene contenido, atendiendo al modelo mcdowelliano de la intencionalidad. Dado que tal consecuencia es indeseable en el proyecto filosófico de McDowell, esto mostraría que existe una tensión lógica y conceptual entre la concepción de McDowell de la experiencia como un proceso pasivo y su (...) concepción de las condiciones para el contenido. Para cumplir este objetivo, primero explicaré qué significa sostener que la percepción es pasiva, en el sentido en el que lo afirma McDowell. Segundo, propondré que si uno asume el modelo mcdowelliano de la intencionalidad, el contenido y la pasividad, no parecer ser posible que la percepción sea al mismo tiempo tanto pasiva como un estado con contenido (i.e. un estado intencional).

Este artigo tem o objetivo de expor a contra doutrina dionisíaca ao otimismo a partir da discussão sobre a interpretação que o filósofo Friedrich Nietzsche faz de Sócrates no livro _O nascimento da tragédia_. Nossa discussão traz em perspectiva a crítica nietzschiana ao denominado socratismo estético, o qual coloca a filosofia socrática longe da sua proposta para o dionisíaco na arte. Para tanto, reconstruímos os argumentos de Nietzsche e investigamos o alcance dos mesmos, como também apresentamos as considerações de Paul (...) de Man sobre a tensão emergente. Como conclusão, apontamos para a abrangência dos conceitos de pessimismo e otimismo dentro do escopo construído. (shrink)

La flexibilidad y la mercantilización de lo espiritual ¿son aspectos característicos de la cultura contemporánea? Centrado en los casos de Alemania, Inglaterra y Francia, el artículo detalla cómo el romanticismo literario se articula como un movimiento pionero de la espiritualidad flexible, proceso que se entrelaza con su rol seminal en la formación del campo literario moderno. El crecimiento económico y demográfico sostenidos en Europa desde el s. XV, así como la alfabetización impulsada por el protestantismo, construyen un moderno público lector (...) que da pie —durante el s. XVIII— a la revolución y diversificación de la lectura, lo que promueve la difusión de incipientes tendencias modernas (ciencia, Ilustración, prensa). Oponiéndose parcialmente a estas tendencias y extendiendo la diversificación de lo impreso, surge la tendencia romántica. Sus autores flexibilizan la espiritualidad más allá de las convenciones religiosas de la época —y aportan a la formación del campo literario— (1) caracterizando el desencanto y otras formas de malestar moderno; (2) multiplicando el lenguaje imaginario-trascendente; (3) brindando connotaciones metafísicas al genio artístico; (4) promoviendo la autonomía y libertad expresiva del arte. La evidencia indica que el mercado fue una condición histórica básica para la EF. Se sugiere que esta flexibilidad se muestra como una adaptación de la espiritualidad a las circunstancias empíricas de la modernidad, la cual conlleva nuevas necesidades de sentido y una mayor capacidad para divergir de los relatos religiosos tradicionales.

This paper is about the ontology of a cancer diagnosis at high-end hospitals in Colombia. Drawing on a seventeen-month ethnographic fieldwork study in this country, it pays attention to how dermatologists, pathologists, and oncologists looked at my partner’s skin during a routine medical checkup and enacted two seemingly contradictory diagnoses: a lethal melanoma and a benign dysplastic nevus—commonly known as mole. Because their differences under the microscope or through dermatology goggles may be subtle, physicians often disagree on what they see. (...) When medical services are not unrelated to the economic possibilities of patients to pay for them, what emerges through a microscope might be different. With neoliberal medical reforms in Colombia as background, this paper focuses on the ontological indeterminacy of cancer and its relationship to high-end hospitals and a patient who could, albeit not without effort, pay for the treatment. Thus, I argue that how physicians saw was not unrelated to what they saw and therefore to their practices of medicine in neoliberal Colombia. How do medical practices and ways of seeing in Colombia enter into composition with the bodies they study? Could the same skin tissue simultaneously be cancerous and noncancerous? (shrink)

La infancia es un hecho social y por este principio no se reduce a una única expresión. En Colombia, las investigaciones de la memoria histórica han omitido esta concepción sociológica al resumir la interacción de la guerra y la infancia al estudio del reclutamiento de menores de edad. Ante esto, este artículo invita a construir una memoria histórica de las infancias olvidadas y desprovistas de existencia en la narración del conflicto armado. Para tal fin, propone empezar por cuatro infancias (la (...) desplazada, la masacrada, la desaparecida y la violentada sexualmente), tomando en cuenta algunas herramientas metodológicas e interpretativas para abordarlas.

El problema que ocupa las reflexiones del siguiente texto es sobre la dificultad de la descripción del sustantivo cuir. Apoyándose en distintos textos, el presente ensayo postula el entendimiento de lo cuir como verbo, es decir encuiramiento. En este segundo sentido, lo cuir viene a ser proceso no terminado, crítica placentera que abre un espacio de futuridad en medio de una cultura condenada a repetir reactivamente el pasado. A partir de una selección de obras de la literatura latinoamericana se muestran (...) diferentes ejemplos de trama cuir que dislocan el ordenamiento heteronormado, desacralizan lo establecido, develan lo inacabado y abren de este modo posibilidades de cambio en el lenguaje.

Atherosclerosis is the major cause of death in the industrialised world. Though much work on the pathogenesis of atherosclerosis points to 'oxidised' low density lipoprotein (LDL) as a key aetiological feature in the generation of the atherosclerotic plaque, the nature of this 'oxidised' LDL in vivo remains an enigma. We argue here that glycated LDL shows many of the characteristics attributed to 'oxidised LDL' and may be the source of the latter in vivo. These include the increased uptake and impaired (...) degradation of glycated LDL by macrophages and the stimulation of transendothelial chemotaxis of monocytes, cytokine secretion and platelet aggregation. We hypothesise that the covalent binding of glycated LDL to the endothelial cell wall may result in the formation of the early atherosclerotic lesion of the fatty streak and that apolipoprotein E may mediate the physiological clearance of glycated moieties. The proposed role of glycation in the pathogenesis of atherosclerosis would explain its high incidence among diabetics and the contentious epidemiological and experimental correlations between dietary sugar and atherosclerosis.

The study on argumentation has been developed until it becoming into an independent studying field since mid last century. Nowadays, this field embraces its own academic structure of magazines, books series, societies, symposiums, Internet Web Pages, experts systems, and it even takes place within departments and curriculums concerning certain Universities' media, which attempt to give an academic discipline shape to the argumentation..

For more than a century, Harlem has been the epicenter of black America, the celebrated heart of African American life and culture—but it has also been a byword for the problems that have long plagued inner-city neighborhoods: poverty, crime, violence, disinvestment, and decay. Photographer Camilo José Vergara has been chronicling the neighborhood for forty-three years, and Harlem: The Unmaking of a Ghetto is an unprecedented record of urban change. Vergara began his documentation of Harlem in the tradition of such (...) masters as Helen Levitt and Aaron Siskind, and he later turned his focus on the neighborhood’s urban fabric, both the buildings that compose it and the life and culture embedded in them. By repeatedly returning to the same locations over the course of decades, Vergara is able to show us a community that is constantly changing—some areas declining, as longtime businesses give way to empty storefronts, graffiti, and garbage, while other areas gentrify, with corporate chain stores coming in to compete with the mom-and-pops. He also captures the ever-present street life of this densely populated neighborhood, from stoop gatherings to graffiti murals memorializing dead rappers to impersonators honoring Michael Jackson in front of the Apollo, as well as the growth of tourism and racial integration. Woven throughout the images is Vergara’s own account of his project and his experience of living and working in Harlem. Taken together, his unforgettable words and images tell the story of how Harlem and its residents navigated the segregation, dereliction and slow recovery of the closing years of the twentieth century and the boom and racial integration of the twenty-first century. A deeply personal investigation, Harlem will take its place with the best portrayals of urban life. (shrink)

Dentro de las tesis que definen la metafísica de Leibniz, destaca aquella según la cual las esencias encierran una pretensión a la existencia. Esta tesis ha despertado un singular interés entre los comentaristas de Leibniz, dando origen a un debate que enfrenta a aquellos que defienden una interpretación metafórica con aquellos que profesan una interpretación literal: si el primer grupo sostiene que tal pretensión ha de entenderse como una atribución metafórica en virtud de la cual las esencias, desprovistas de tal (...) característica, son susceptibles de alcanzar la existencia al ser actualizadas por Dios, para el segundo grupo, las esencias son portadoras en sí de tal característica, la que debe entenderse entonces como una cualidad real e inherente presente en ellas. A partir de un examen de diversos manuscritos de Leibniz, nuestro propósito es reivindicar una interpretación literal de la tesis de la pretensión de las esencias a la existencia, explicando por qué la interpretación metafórica, además de carecer de fundamento, entraña contradicciones.

Resumen En la siguiente discusión presento algunas objeciones al artículo de Federico Raffo Quintana “La noción de ‘espacio’ en los escritos juveniles de Leibniz”.1 Contra la interpretación de Raffo, quien considera que la concepción del espacio como lugar universal de las cosas es una idea que Leibniz abandona de manera muy temprana -según el autor en 1671-, intento mostrar que esta concepción trasciende sin duda el periodo de los escritos juveniles de Leibniz y que ciertas confusiones conceptuales en la lectura (...) de Raffo hacen que, en vez de ver una armónica continuidad en la teoría del espacio de Leibniz, vea en ella una ruptura en su evolución histórica, a la que, además, asocia algunas dicotomías discutibles o espurias.In this paper I introduce objections to Federico Raffo Quintana’s paper “The Notion of ‘Space’ in the Young Leibniz Writings”. Against Raffo, who considers that the Leibnizian conception of space as the universal place of things is an idea that Leibniz early abandons -Raffo says in 1671-, I will try to show that such a conception goes beyond the Leibniz’s young writings and that it is because of some conceptual confusions in Raffo’s survey that he, instead of seeing a harmonic continuity in Leibniz’s theory of space, sees a rupture in its historical evolution, associating to it some disputable or spurious dichotomies.

An algebraic interpretation of multigraph networks is introduced in relation to conscious experience, brain and body. These multigraphs have the ability to merge by an associative binary operator \(\odot \), accounting for biological composition. We also study a mathematical formulation of splitting layers, resulting in a formal analysis of the transition from conscious to non-conscious activity. From this construction, we recover core structures for conscious experience, dynamical content and causal constraints that conscious interactions may impose. An important result is the (...) prediction of structural topological changes after conscious interactions. These results may inspire further use of formal mathematics to describe and predict new features of conscious experience while aligning well with formal tries to mathematize phenomenology, phenomenological tradition and applications to artificial consciousness.

Finalmente, se indicarán una serie de objeciones que obstaculizarían las pretensiones de universalidad, univocidad y neutralidad, tensionando con ello la intencionalidad teórica del filósofo italiano. Metodológicamente hablando, se tratará de un análisis descriptivo y sistemático, no prescriptivo ni tampoco axiológico. (shrink)

En el presente texto se realiza un análisis sobre la utilidad del método de los experimentos mentales en filosofía. Dicha utilidad se da en tanto que el experimento usado sea legítimo, esto es, que cumpla con ciertas exigencias teóricas.

Tomando como referencia un tipo específico de experimentos mentales ilegítimos, el texto se propone presentar una explicación al anterior fenómeno basada en la relación de (...) las nociones de conocimiento y necesidad lógica. Igualmente, se presentan dos formas posibles de evitar el recurso excesivo a experimentos mentales de poca utilidad. (shrink)

ABSTRACT Between the 1910s and the 1940s, American naturalists carried out a number of ornithological expeditions in Colombia. With the help of Colombian naturalists, thousands of skins were brought to natural history museums in the United States. By 1948 these birds had become an important treasure: American ornithologists declared Colombia the nation with the most bird species. This story sheds new light on the role science played in the expansion of U.S. political, economic, and cultural influence in Latin America in (...) the early twentieth century, as well as on the relation between nationalist movements in Latin America and the study of the natural world. Recognizing a complex but fruitful interaction between nationalist policies and imperial practices proves important for understanding the success of the naturalists' enterprise in Colombia. (shrink)

El siguiente ensayo tiene como objetivo delimitar los argumentos bases que dan origen a la teoría política conocida como atomismo. Para ello será necesario hacer un análisis de sus orígenes en las proposiciones del contrato social, así como de las razones por las cuales se considera al individuo como autosuficiente, para luego ver cómo esto mismo les da un fundamento a los derechos de esta índole. Ello nos demostrará la importancia de replantear estos argumentos, si es que hacen posible la (...) convivencia entre otros, y cómo es que un sistema que requiera de mayor cooperación es contrario al atomismo político. Finalmente, se verán las implicaciones contradictorias y los elementos que juegan en contra de formar parte de este pensamiento, sobre todo en su forma radical. (shrink)

Theoretical accounts of negative expressives such as damn have ascribed two main properties to this type of adjective, namely that they are typically speaker-oriented, and that they can be flexible with regard to their syntactic attachment. However, it is not clear what this means during online sentence processing. For example, is it effortful for comprehenders to derive the speaker's negative attitude conveyed by an expressive adjective, or is it a rapid, automatic process? And do comprehenders understand the speaker's attitude regardless (...) of the expressive's syntactic position? The current work provides the first evidence supporting theoretical claims by investigating the incremental processing of Italian negative expressive adjectives. In an eye-tracking study, we show that expressive content is rapidly integrated with information about the speaker's attitude, resulting in the anticipation of an upcoming referent, regardless of the expressive's syntactic realization. We argue that comprehenders use expressives as an ostensive cue that allows for automatic retrieval of the speaker's negative attitude. (shrink)
