RESUMEN Se presentan los resultados de la investigación La calidad de vida en pacientes con catarata senil atendidos en Nuevitas de junio a diciembre del 2016, con el objetivo de demostrar el impacto social de la cirugía. Para el estudio descriptivo, longitudinal, prospectivo realizado se seleccionaron 65 pacientes, los cuales constituyen la muestra seleccionada. Para medir el impacto se aplicó una planilla de recolección de datos, y el cuestionario de calidad de vida relativa a la visión pre y postoperatoria. Se (...) concluye que todos los pacientes fueron operados debido a un deterioro visual y funcional marcado. Luego de la cirugía se logró una recuperación visual satisfactoria, con una mejor calidad de vida que revela valores altamente significativos desde el punto de vista clínico, psicológico y social que contribuyeron a la reincorporación de estos ancianos a la sociedad. ABSTRACT It is presented the results of the investigation “The quality of life in patients with senile cataract attended in Nuevitas from June to December, 2016", with the objective to demonstrate the social impact of the surgery. For the descriptive, longitudinal, pilot study were selected 65 patients, which constitute the chosen sample. To measure the impact there was applied a chart of information compilation, and the questionnaire of quality of life relative to the vision pre and postoperative. It was concluded that all the patients were operated due to a pronounced visual and functional deterioration. After the surgery a satisfactory visual recovery was achieved, with a better quality of life that reveals highly significant values from the clinical, psychological and social point of view that they contributed to the reincorporation of these elders to the society.

Este artículo muestra los resultados de un estudio de caso centrado en la puesta en marcha de un programa didáctico en un centro de primaria. El programa constó de dos actuaciones didácticas distintas en dos períodos de prácticum de magisterio. La primera se realizó con 2 grupos de 6º durante 5 sesiones y la segunda con 2 grupos de 5º durante 4 sesiones. Participaron 53 estudiantes. El tema escogido fue la Guerra Civil. Se combinaron conocimientos y emociones. De las observaciones (...) de la docente en prácticas, así como del análisis temático realizado sobre las intervenciones y producciones del alumnado, se evidencia cómo la simbiosis entre una educación patrimonial crítica, asentada sobre la memoria como forma de entender el paisaje, y la realización de salidas contextualizadas al entorno, refuerzan en el alumnado destrezas cívico-sociales.

Nowadays, there is a quite considerable amount of literature on the use of analogy or more generally of inferences by parallel reasoning in contemporary legal reasoning, and particularly so within Common Law. These studies are often motivated by researches in artificial intelligence seeking to develop suitable software-support for legal reasoning. Recently; Rahman/Iqbal/Soufi (2020) developed a dialogical approach in the framework of Constructive Type Theory to what in Islamic Jurisprudence was called qiyās or correlational inferences. In their last chapter the authors (...) suggested that such an approach contributes to the study of patterns of reasoning by precedent cases within contemporary common Law. In the present paper we will further motivate the deployment within Civil and Common Law of the dialogical framework developed in Rahman/Iqbal/Soufi (2020). After a presentation of Scott Brewer's take on analogy within Common Law, that has striking structural similarities to reasoning by precedent case rooted in ratio legis (known in Islamic Jurisprudence as qiyās al-'illa or correlational inference by the occasioning factor), we will illustrate the implementation of the framework with a brief discussion of some cases of legal reasoning based in Spanish Civil Law but where the accent is put in the emerging ruling rather than in the existing of a case as in Common Law. Moreover; quite surprisingly, the case under study suggests that even cases of Law-interpretation fit the argumentation pattern of qiyās al-'illa. A caveat: in the present paper we will focus mainly in discussing the dynamics of the meaning constitution involved rather than in setting the rules of the underlying dialogical framework, the latter is the subject of a follow-up paper.

En la primera parte de este trabajo se busca explicar por qué tanto la figura personal de Jorge Luis Borges como su propia obra han generado alguna clase de recelo o “miedo”. Las prevenciones de orden político hacia su persona, por un lado, y las complejas relaciones entre la dificultad y disfrute que surgen en el tratamiento sus textos, por el otro, son dos dimensiones interconectadas que participan en la configuración de una representación cultural sobre Borges en su propio país, (...) Argentina. Como un método para vencer “el miedo a Borges”, en la segunda parte se muestra cómo muy diversas y heterogéneas producciones de la cultura popular pueden llegar a ser vías de acceso para empezar a tratar temas de su obra. En la tercera parte, que es el núcleo de este trabajo, se presenta el desarrollo una investigación que recurrió a un capítulo de la serie de dibujos animados “Los Simpson” como vía de acceso a un texto de Borges. Los resultados ofrecen evidencia empírica a favor de las dos hipótesis evaluadas. En primer lugar, una tarea preparatoria con una producción de la cultura popular parece favorecer la comprensión global. En segundo lugar, la lectura en voz alta y comentada parece favorecer no sólo la comprensión en general sino también el disfrute de los textos. (shrink)

En su libro The Cinematic Footprint (2012), la teórica de los estudios sobre el cine Nadia Bozak propone un análisis de la producción cinematográfica basado en su relación con los consumos y los recursos naturales de los que ésta depende. Desde este punto de vista, este artículo parte de tres escenas de la filmografía del realizador ruso Andrei Tarkovsky para examinar, desde las condiciones materiales de su producción, un campo de interacciones entre imagen y transformación del paisaje más allá de (...) la representación. El trabajo de Tarkovsky es entonces analizado en este texto desde el marco de las relaciones trabadas a lo largo del siglo XX entre imagen, extractivismo y crecimiento vegetal. En particular, los planos examinados son puestos en relación con programas de colonización agraria, agricultura de precisión y técnicas de reforestación como el bombardeo de semillas. El contraste entre la naturaleza extractivista de la mediación por la imagen en estos casos y el carácter de "práctica de cine vegetal" con el que ha sido descrito el cine de Tarkovsky (Uhlin 2015) invitan a rearticular la diferencia entre imagen y crecimiento vegetal en términos de los llamados "medios elementales" introducidos durante la última década en el ámbito de la teoría de los medios.

El objetivo de este artículo es presentar los diferentes conceptos del Cosmismo ruso como una alternativa al vacío existencial que permea todo el Transhumanismo. Si tenemos en cuenta que el fenómeno original del Cosmismo ruso es una síntesis de enfoques científicos generales, científico-naturales y culturales para el estudio de la dimensión cosmoplanetaria del hombre, es posible ver en el movimiento del Transhumanismo, por el contrario, supone una amenaza para la humanidad que podría culminar en la realización de sus ideales y (...) sobrepasar todas las zonas de riesgo existentes: la utilización de la innovación tecnológica para el reemplazo gradual del cuerpo humano natural en un cyborg puede llegar a destruir la humanidad tal y como la conocemos. El artículo muestra que el Cosmismo ruso es fundamentalmente diferente del Transhumanismo por la presencia de una enseñanza ética según la cual las nuevas habilidades evolutivas deben tener como base la mejora espiritual y moral de la persona. Al reducir la conciencia humana a un medio electrónico, el Transhumanismo devalúa los valores de la cultura europea. Junto a los sueños audaces sobre las posibilidades evolutivas del hombre, el Cosmismo ruso contiene programas de investigación en los que demuestra que la materia viva de nuestro planeta ha sido generada por diversas radiaciones cósmicas. De ahí que su filosofía anteponga, ante la magnitud que puede llegar a alcanzar la búsqueda de la inmortalidad defendida por el Transhumanismo, el concepto de la naturaleza cósmica de la vida y el "corazón" como un centro psicofisiológico especial de una persona, y que son estos dos conceptos los que podrán contribuir a resolver el problema del estrecho contacto con las tecnologías de última generación.

RESUMEN El presente artículo trata de mostrar las varias y diversas interpretaciones y posiciones existentes con respecto a la filosofía de Feuerbach, lo cual revela la influencia e importancia de su pensamiento. Así mismo, más allá de los diversos intentos por periodizar la obra de Feuerbach, el artículo trata de mostrar en qué medida es posible afirmar la existencia de un principio interno explicativo de su filosofía, el cual puede encontrarse en el concepto mismo de crítica, referido tanto a su (...) método como a su actitud filosófica. Esta crítica tiene, en cualquier caso, un sentido positivo y trata de reafirmar una concepción plena del ser humano. ABSTRACT This paper tries to show the various and diverse interpretations and positions regarding Feuerbach's philosophy, what reveals the influence and importance of his thought. Likewise, beyond the various efforts to periodize Feuerbach's works, it tries to show how it is possible to affirm the existence of an internal explanatory principle to his philosophy, which can be found in the very concept of critique, referring both to his philosophical method and attitude. This critique has, in any case, a positive sense and tries to reassert a full conception of human beings. (shrink)

From the most prominent thinkers in Latin American philosophy, literature, politics, and social science comes a challenge to conventional theories of globalization. The contributors to this volume imagine a discourse in which revolution requires no temporalized march of progress or takeovers of state power but instead aims at local control and the material conditions for human dignity.

Obesity is characterized by the accumulation of an excessive amount of fat mass in the adipose tissue, subcutaneous, or inside certain organs. The risk does not lie so much in the amount of fat accumulated as in its distribution. Abdominal obesity is an important risk factor for cardiovascular diseases, diabetes, and cancer, having an important role in the so-called metabolic syndrome. Therefore, it is necessary to prevent, detect, and appropriately treat obesity. The diagnosis is based on anthropometric indices that have (...) been associated with adiposity and its distribution. Indices themselves, or a combination of some of them, conform to a big picture with different values to establish risk. Anthropometric indices can be used for risk identification, intervention, or impact evaluation on nutritional status or health; therefore, they will be called anthropometric health indicators. We have found 17 AHIs that can be obtained or estimated from 3D human shapes, being a noninvasive alternative compared to X-ray-based systems, and more accessible than high-cost equipment. A literature review has been conducted to analyze the following information for each indicator: definition; main calculation or obtaining methods used; health aspects associated with the indicator ; criteria to classify the population by means of percentiles or cutoff points, and based on variables such as sex, age, ethnicity, or geographic area, and limitations.

In this article, I propose a unified account of systemic emergence, downward causation, and interlevel integrative explanations. First, I argue for a relational-transformational notion of emergence and a structural-relational account of downward causation in terms of both its transformational and conditioning effects. In my view, downward causation can avoid the problems traditionally attributed to it, provided that we are able to reconceptualize the notion of ‘whole’ and that form of causality in a purely relational way. In this regard, I distinguish (...) contextual or whole-to-part causation from downward causation, the latter defined by the existence of second-order structural relations. Finally, I argue that while emergence and downward-structural causation imply the in-principle failure of micro-determinism and therefore micro-reduction, they do not rule out the possibility of any type of explanation. On the contrary, they call for the development of interlevel integrative explanations. (shrink)

Ageing is associated with declines in several cognitive abilities including working memory. The goal of the present study was to assess whether emotional information could reduce the age gap in the quantity and quality of representations in visual WM. Young and older adults completed a serial image recognition task and a colour-image binding task. Results of the SIR task showed worse performance for negative than neutral and positive images within the older group, hence enlarging the age gap in WM. In (...) the CIB task, recall precision was lower in the old than young adults, showing an ageing decline in the quality of WM representations. Positive images tended to improve precision, but this boost was similar for both age groups. In sum, emotional content did not reduce the age gap in visual WM. (shrink)

Philosophers of well-being have tended to adopt a foundationalist approach to the question of theory and measurement, according to which theories are conceptually before measures. By contrast, social scientists have tended to adopt operationalist commitments, according to which they develop and refine well-being measures independently of any philosophical foundation. Unfortunately, neither approach helps us overcome the problem of coordinating between how we characterize well-being and how we measure it. Instead, we should adopt a coherentist approach to well-being science.

Feelings are conscious mental events that represent body states as they undergo homeostatic regulation. Feelings depend on the interoceptive nervous system (INS), a collection of peripheral and central pathways, nuclei and cortical regions which continuously sense chemical and anatomical changes in the organism. How such humoral and neural signals come to generate conscious mental states has been a major scientific question. The answer proposed here invokes (1) several distinctive and poorly known physiological features of the INS; and (2) a unique (...) interaction between the body (the ‘object’ of interoception) and the central nervous system (which generates the 'subject' of interoception). The atypical traits of the INS and the direct interactions between neural and non‐neural physiological compartments of the organism, neither of which is present in exteroceptive systems, plausibly explain the qualitative and subjective aspects of feelings, thus accounting for their conscious nature.

Mental simulation — such as imagining tilting a glass to figure out the angle at which water would spill — can be a way of coming to know the answer to an internally or externally posed query. Is this form of learning a species of inference or a form of observation? We argue that it is neither: learning through simulation is a genuinely distinct form of learning. On our account, simulation can provide knowledge of the answer to a query even (...) when the basis for that answer is opaque to the learner. Moreover, through repeated simulation, the learner can reduce this opacity, supporting self-training and the acquisition of more accurate models of the world. Simulation is thus an essential part of the story of how creatures like us become effective learners and knowers. (shrink)

We explore how principles predicting the success of a medical information commons advantaged or disadvantaged three MIC initiatives in three Canadian provinces. Our MIC case examples demonstrate that practices and policies to promote access to and use of health information can help improve individual healthcare and inform a learning health system. MICs were constrained by heterogenous health information protection laws across jurisdictions and risk-averse institutional cultures. A networked approach to MICs would unlock even more potential for national and international data (...) collaborations to improve health and healthcare. (shrink)

Downward causation exercised by emergent properties of wholes upon their lower-level constituents’ properties has been accused of conceptual and metaphysical incoherence. Only upward causation is usually peacefully accepted. The aim of this paper is to criticize and refuse the traditional hierarchical-vertical way of conceiving both types of causation, although preserving their deepest ontological significance, as well as the widespread acceptance of the traditional atomistic-combinatorial view of the entities and the relations that constitute the so-called ‘emergence base’. Assuming those two perspectives (...) with no reserves, we are condemned to confine our debate to the question of whether reified wholes can have the power to downwardly change or influence their lower-level parts, a question which seems profoundly misleading to me. I therefore propose an alternative relational ontological view, assuming a straightforward horizontal and intra-level way of representing those putative cases of cross-level causation. I finally confront two recent replies to Kim’s well-known objections to DC—Craver and Bechtel and Kistler :595–609, 2009)—, emphasizing their global positive approaches, as well as the reasons why their accounts still seem insufficient to me. I conclude arguing that both Kim’s principle of the causal closure of the physical domain and its allegation of an overdetermination in cases of DC can be surpassed by the new relational ontological perspective presented here.

Both philosophers and psychologists have argued for the existence of distinct kinds of explanations, including teleological explanations that cite functions or goals, and mechanistic explanations that cite causal mechanisms. Theories of causation, in contrast, have generally been unitary, with dominant theories focusing either on counterfactual dependence or on physical connections. This paper argues that both approaches to causation are psychologically real, with different modes of explanation promoting judgments more or less consistent with each approach. Two sets of experiments isolate the (...) contributions of counterfactual dependence and physical connections in causal ascriptions involving events with people, artifacts, or biological traits, and manipulate whether the events are construed teleologically or mechanistically. The findings suggest that when events are construed teleologically, causal ascriptions are sensitive to counterfactual dependence and relatively insensitive to the presence of physical connections, but when events are construed mechanistically, causal ascriptions are sensitive to both counterfactual dependence and physical connections. The conclusion introduces an account of causation, an "exportable dependence theory," that provides a way to understand the contributions of physical connections and teleology in terms of the functions of causal ascriptions.

Educational policy and social sciences researchers have been studying dishonest behaviors among students for a long time. In this bibliometric study we examine the extant literature on academic dishonesty until 2017. We also analyze the specific case of the literature on plagiarism since it is arguably one of the most common academic dishonest behavior. We aim at identifying the intellectual structure of the field of academic dishonesty and plagiarism. Results show that Donald L. McCabe and Richard L. Marsh appear as (...) the most productive authors. Furthermore, Whitley, 235–274, 1998) “Factors associated with cheating among college students: A review”, and Pennycook, 201–230, 1996), entitled “Borrowing others’ words: Text, ownership, memory, and plagiarism” are the most cited publications on academic dishonesty and on plagiarism, respectively. Additionally, a strong connection between the McCabe and Treviño articles emerged from the co-citation analysis on academic dishonesty, and also a strong relationship between Pennycook, 201–230, 1996) and Pecorari, 317–345, 2003), suggesting that these articles are strongly connected. Results suggest that these are the most influential authors and articles of the field. (shrink)

ABSTRACTThe understanding of a wide array of practices related to fraud, bribery, corruption, and more widely, illicit practices have been capturing the attention of practitioners and management researchers worldwide. A substantial portion of the extant research has used university students to measure their actual or intended cheating behaviours and often studies have tested for variations across countries and cultures. We highlight some major concerns in this stream of inquiry and discuss both the definition and some inconclusive results in prior studies, (...) namely those deriving from differences in cheating behaviour across different cultural contexts. We suggest the need to examine intentionality, and further advance that intentionality may assume a reactive or a proactive essence. Depending on the social and formal contexts of different countries, both reactive and proactive intentions lead to distinct moral concerns, which we name in this work omorality or immorality.

Le terme ktitor accompagne souvent la représentation d'un acte de don dans la peinture murale byzantines et post-byzantines. Même si le terme "ktitor" a été traduit le plus souvent par "fondateur", sémantiquement et historiquement, on retrouve dans le mot le sens de possession. Les ktitores - des propriétaires modaux, offrent leurs dons, dont le destinataire final est Dieu. Les panneaux votifs de Théodore Métochite , du sebastokrator Kalojan , de Stefan Uroš III , de Mircea l'Ancien témoignent des droits, des (...) intentions et de la foi du ktitor. Avec le christianisme, le sens du don s'est inversé et out don humain n'est qu'un contre-don à Dieu pour son sacrifice premier. (shrink)

In this article I address the issue of the ontological conditions of possibility for a naturalistic notion of emergence, trying to determine its fundamental differences from the atomist, vitalist, preformationist and potentialist alternatives. I will argue that a naturalistic notion of ontological emergence can only succeed if we explicitly refuse the atomistic fundamental ontological postulate that asserts that every entity is endowed with a set of absolutely intrinsic properties, being qualitatively immutable through its extrinsic relations. Furthermore, it will be shown (...) that, ironically enough, this metaphysical assumption is implicitly shared by all the above mentioned alternatives to Emergentism. The current article concludes that the notion of organization by itself is not enough, and that ontological emergence can only be justified by assuming a relational ontological perspective that, in opposition both to atomism and holism, defends that the existence-conditions, the identity and the causal behavior of any emergent systemic property can only be conceived, and explained, as constructed by and through specific networks of qualitatively transformative relational processes that occur between the system’s components and between the system and its environment. Additionally, I try to explain how one can make sense of the idea that an emergent phenomenon is both dependent on, and autonomous from, its emergence base. (shrink)

This study sought to assess barriers and enhance readiness to consent to home and Planned Parenthood HIV testing among 60 out-patients from a mental health and substance abuse clinic in rural Appalachia. Testing barriers included not knowing where to get tested, lack of confidentiality, and loss of partners if one tested sero-positive. The intervention yielded lowered HIV stigma, increase in HIV knowledge, and agreement to take the HIV home test. These results are encouraging because they suggest that a brief educational (...) intervention is a critical pathway to the success of the National Institutes on Drug Abuse’s Seek, Test, Treat, and Retain initiative in poor rural counties.

Assisted suicide, many argue, honors self‐determination in returning control of their dying to patients themselves. But physician assistance and measures proposed to safeguard patients from coercion in fact return ultimate authority over this “private and deeply personal” decision to medicine and society.

Generating an account that can sidestep the disagreement among substantive theories of well-being, while at the same time still providing useful guidance for well-being public policy, would be a significant achievement. Unfortunately, the various attempts to remain agnostic regarding what constitutes well-being fail to either be an account of well-being, provide useful guidance for well-being policy, or avoid relying on a substantive well-being theory. There are no theory-free lunches in well-being policy. Instead, I propose an intermediate account, according to which (...) well-being is constituted by endorsed veridical experiences. This account refers back to theories of well-being but does so as agnostically as possible. An intermediate account of well-being is meant as a policy guiding compromise between the different theories of well-being that make claims regarding what constitutes well-being. An intermediate account does as well as can be hoped for in providing a basis for well-being policy. (shrink)

The issue of how to incorporate the individual's first‐hand experience of illness into broader medical understanding is a major question in medical theory and practice. In a philosophical context, phenomenology, with its emphasis on the subject's perception of phenomena as the basis for knowledge and its questioning of naturalism, seems an obvious candidate for addressing these issues. This is a review of current phenomenological approaches to medicine, looking at what has motivated this philosophical approach, the main problems it faces and (...) suggesting how it might become a useful philosophical tool within medicine, with its own individual, but interrelated, contribution to make to current medical debates. After the general background, there is a brief summary of phenomenological ideas and their current usage in a medical context. Next is a critique of four key claims within current phenomenological medical works, concerning both the role phenomenology plays and the supposedly clear divide between phenomenology and other approaches. There are significant problems within these claims, largely because they overlook the complexity of the questions they consider. Finally, there is some more in‐depth examination of phenomenology itself and the true complexity of phenomenological debate concerning subjectivity. The aim is to show that it will be both more productive and truer to phenomenology itself, if we use phenomenology as a philosophical method for explicating and gaining deeper understanding of complex and fundamental problems, which are central to medicine, rather than as providing simple, but flawed solutions.

This paper proposes a five-part empirical typology of interconnections of race and class. We describe the mechanisms whereby (1) race is a form of class relation; (2) race relations and class relations reciprocally affect each other; (3) race acts as a sorting mechanism into class locations; (4) race acts as a mediating linkage to class locations; and (5) race interacts with class in determining other outcomes. Rather than insisting on one or another mechanism as the overarching framework for conceptualising the (...) interconnections between race and class, we propose a theoretical integration of all five within a functionalist model. The model reconciles the empirical effects of race variables with a class-functionalist explanation of race. Our typology of interconnections is useful for situating concrete empirical phenomena, and our theoretical integration of those interconnections offers a coherent explanatory system that captures the recursive causality of race and class.
