This paper focuses on the idea of tragedy in Marx. A comparison between Capital and Economic and Philosophic Manuscripts of 1884 is proposed, in order to assert that what happens to the human being goes through the understanding of his tragic condition in the bosom of capitalist production. It maintains that tragedy is the conflict in whose development the human being sacrifices his essential forces with the intention of producing new contents of life for him.

Understanding how people behave when facing hazardous situations, how intrinsic and extrinsic factors influence the risk taking (RT) decision making process and to what extent it is possible to modify their reactions externally, are questions that have long interested academics and society in general. In the spheres of Occupational Safety and Health (OSH), the military, finance and sociology, this topic has multidisciplinary implications because we all constantly face risk taking situations. Researchers have hitherto assessed risk taking profiles by conducting questionnaires (...) prior to and after the presentation of stimuli; however, this can lead to the production of biased, non-realistic, risk taking profiles. This is due to the reflexive nature of choosing an answer in a questionnaire, which is remote from the reactive, emotional and impulsive decision making processes inherent to real, risky situations. One way to address this question is to exploit VR capabilities to generate immersive environments that recreate realistic seeming but simulated hazardous situations. We propose VR as the next-generation tool to study risk taking processes, taking advantage of the big four families of metrics which can provide objective assessment methods with high ecological validity: the real-world risks approach (high presence VR environments triggering real-world reactions), embodied interactions (more natural interactions eliciting natural behaviours), stealth assessment (unnoticed real-time assessments offering efficient behavioural metrics) and physiological real-time measurement (physiological signals avoiding subjective bias). Additionally, VR can provide an invaluable tool, after the assessment phase, to train in skills related to risk taking due to its transferability to real-world situations. (shrink)

This 1999 volume takes a critical look at the current divide over immigration policies. It hopes to shed light on the debate by bringing together papers that investigate the link between trade and factor mobility, particularly labour migration, from theoretical and empirical perspectives. It examines the substitutability between trade and migration, the impact of regional integration on the location of economic activity, the role of public goods provisions, and the political economy of migration. Several papers quantify the link between trade, (...) trade policies, migration and income distribution in sending and receiving nations using econometric methods and general equilibrium simulations. Case studies of past and present migration episodes are also presented: the impact of NAFTA on migratory pressure and wage gaps; the trade-migration links between Eastern and Western Europe; and the historical experience with migration flows in the nineteenth century.

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)

The INBIOSA project brings together a group of experts across many disciplines who believe that science requires a revolutionary transformative step in order to address many of the vexing challenges presented by the world. It is INBIOSA’s purpose to enable the focused collaboration of an interdisciplinary community of original thinkers. This paper sets out the case for support for this effort. The focus of the transformative research program proposal is biology-centric. We admit that biology to date has been more fact-oriented (...) and less theoretical than physics. However, the key leverageable idea is that careful extension of the science of living systems can be more effectively applied to some of our most vexing modern problems than the prevailing scheme, derived from abstractions in physics. While these have some universal application and demonstrate computational advantages, they are not theoretically mandated for the living. A new set of mathematical abstractions derived from biology can now be similarly extended. This is made possible by leveraging new formal tools to understand abstraction and enable computability. [The latter has a much expanded meaning in our context from the one known and used in computer science and biology today, that is "by rote algorithmic means", since it is not known if a living system is computable in this sense (Mossio et al., 2009).] Two major challenges constitute the effort. The first challenge is to design an original general system of abstractions within the biological domain. The initial issue is descriptive leading to the explanatory. There has not yet been a serious formal examination of the abstractions of the biological domain. What is used today is an amalgam; much is inherited from physics (via the bridging abstractions of chemistry) and there are many new abstractions from advances in mathematics (incentivized by the need for more capable computational analyses). Interspersed are abstractions, concepts and underlying assumptions “native” to biology and distinct from the mechanical language of physics and computation as we know them. A pressing agenda should be to single out the most concrete and at the same time the most fundamental process-units in biology and to recruit them into the descriptive domain. Therefore, the first challenge is to build a coherent formal system of abstractions and operations that is truly native to living systems. Nothing will be thrown away, but many common methods will be philosophically recast, just as in physics relativity subsumed and reinterpreted Newtonian mechanics. -/- This step is required because we need a comprehensible, formal system to apply in many domains. Emphasis should be placed on the distinction between multi-perspective analysis and synthesis and on what could be the basic terms or tools needed. The second challenge is relatively simple: the actual application of this set of biology-centric ways and means to cross-disciplinary problems. In its early stages, this will seem to be a “new science”. This White Paper sets out the case of continuing support of Information and Communication Technology (ICT) for transformative research in biology and information processing centered on paradigm changes in the epistemological, ontological, mathematical and computational bases of the science of living systems. Today, curiously, living systems cannot be said to be anything more than dissipative structures organized internally by genetic information. There is not anything substantially different from abiotic systems other than the empirical nature of their robustness. We believe that there are other new and unique properties and patterns comprehensible at this bio-logical level. The report lays out a fundamental set of approaches to articulate these properties and patterns, and is composed as follows. -/- Sections 1 through 4 (preamble, introduction, motivation and major biomathematical problems) are incipient. Section 5 describes the issues affecting Integral Biomathics and Section 6 -- the aspects of the Grand Challenge we face with this project. Section 7 contemplates the effort to formalize a General Theory of Living Systems (GTLS) from what we have today. The goal is to have a formal system, equivalent to that which exists in the physics community. Here we define how to perceive the role of time in biology. Section 8 describes the initial efforts to apply this general theory of living systems in many domains, with special emphasis on crossdisciplinary problems and multiple domains spanning both “hard” and “soft” sciences. The expected result is a coherent collection of integrated mathematical techniques. Section 9 discusses the first two test cases, project proposals, of our approach. They are designed to demonstrate the ability of our approach to address “wicked problems” which span across physics, chemistry, biology, societies and societal dynamics. The solutions require integrated measurable results at multiple levels known as “grand challenges” to existing methods. Finally, Section 10 adheres to an appeal for action, advocating the necessity for further long-term support of the INBIOSA program. -/- The report is concluded with preliminary non-exclusive list of challenging research themes to address, as well as required administrative actions. The efforts described in the ten sections of this White Paper will proceed concurrently. Collectively, they describe a program that can be managed and measured as it progresses. (shrink)

The negative impacts of agriculture on the environment and the inequity that limits access to healthy food for the entire population impede sustainable development. This article reflects contributions to food security and alternatives for transitioning to sustainable food systems. It is concluded that food, as a human right, is a complex and transdisciplinary issue, which must be integrated as a transversal axis in the economic, social, environmental, governance, and cultural dimensions to contribute to sustainable development and therefore the convenience of (...) making the transition from the concept of food security to that of food sustainability.

This research analyzed the ethical-political discussions of distributive justice in national minorities and its incorporation into the Constitutions of Latin American countries. Ethics stands out in its search to dignify the human being, finding two immeasurable positions: (a) the deontological models of justice and equality and their detached subjects, and (b) the communitarian models that rescue the identity contingencies of the subjects. The latter have allowed reflections that recognize the defense of cultural, territorial and linguistic identity as fundamental issues. Finally, (...) the discussion ventures to delimit equity and positive discrimination. (shrink)

En la filosofía y psicología actual existe una discusión actualmente de vital importancia para la comprensión del ser humano, esto es la relación entre las emociones y la vida moral. En este contexto Martha Nussbaum ofrece importantes puntos de reflexión que nos llevan a preguntarnos por aquellas facultades cognitivas que estructuran las emociones morales como la compasión y que diferencian la expresión emocional humana de la de animales no humanos.

En el debate sobre la definición de vida algunos autores consideran que vida ha de entenderse como un género natural. Sin embargo, cuando se afirma que vida es un género natural se asumen también otras ideas vinculadas con la idea de género natural que conviene explicitar, tal y como han mostrado recientemente Bich y Green aunque de manera programática, y ese es precisamente el objetivo planteado aquí; mostrar cuáles son esas implicaciones y señalar las dificultades que surgen al adoptar el (...) discurso sobre los géneros naturales para entender y analizar categorías científicas complejas como, por ejemplo, vida. En este trabajo extendemos esta crítica a las distintas formas de entender los géneros naturales y señalamos cuál es la principal causa de las dificultades que derivan de este planteamiento. In the contemporary philosophy of biology, some authors claim that life is better undertood as a natural kind. This paper questions the metaphysical commitments related to the natural kind approach in relation with the debate of defining life. The goal of this paper is to show how considering life as a natural kind carries out some difficulties and costs. Those difficulties have been partialy shown by Bich and Green concerning the essentialist view of natural kinds. In this paper we extended this criticism to other ways of understanding natural kinds and we argue that such a difficulties are due to the acceptance of an inadequate frame of reference, based on a naïve idea of naturalness and on a natural/conventional dichotomy that is not properly justified.

This study compares cognitive and emotional responses to 360-degree vs. static (2D) videos in terms of visual attention, brand recognition, engagement of the prefrontal cortex, and emotions. Hypotheses are proposed based on the interactivity literature, cognitive overload, advertising response model and motivation, opportunity, and ability theoretical frameworks, and tested using neurophysiological tools: electroencephalography, eye-tracking, electrodermal activity, and facial coding. The results revealed that gaze view depends on ad content, visual attention paid being lower in 360-degree FMCG ads than in 2D (...) ads. Brand logo recognition is lower in 360-degree ads than in 2D video ads. Overall, 360-degree ads for durable products increase positive emotions, which carries the risk of non-exposure to some of the ad content. In testing four ads for durable goods and fast-moving consumer goods (FMCG) this research explains the mechanism through which 360-degree video ads outperform standard versions. (shrink)

Resumen: En este trabajo, se observa la variación fonética del fonema oclusivo bilabial sonoro en el español no estándar en una muestra de hablantes chilenos de ocho ciudades, cuyas ubicaciones geográficas permiten cubrir los principales sectores urbanos del país. En los resultados se evidencia un marcado uso del alófono aproximante labiodental sonoro en este tipo de habla y un comportamiento relativamente homogéneo en todo el país respecto de las principales variantes del fonema oclusivo bilabial sonoro. La comparación del fonema oclusivo (...) bilabial sonoro entre el español no estándar y el estándar muestra marcadas diferencias, datos que sugieren un cambio lingüístico en proceso desde el alófono aproximante bilabial sonoro al alófono aproximante labiodental sonoro.: In this study, we observed the phonetic variation of voiced bilabial occlusive phoneme in non-standard Spanish in a sample of Chilean speakers from cities whose geographical locations allow to cover the main urban sectors of the country. The results that show a marked use of voiced labiodental approximant allophone in this type of speech an a relatively homogenous behaviour in the whole country of the main variants of the voiced bilabial occlusive phoneme are presented. The comparison of voiced bilabial occlusive phoneme between non-standard and standard Spanish shows clear differences, data that suggest a linguistic change in process from voiced bilabial approximant allophone to voiced labiodental approximant allophone.

Es bien conocida la primera filosofía de Ortega y Gasset en torno al "raciovitalismo" y al liberalismo. En cambio, su segunda navegación, en expresión suya, no ha alcanzado aún perfiles precisos ante el público interesado. Nada mejor para ello que revisitar la obra póstuma que mejor representa tal vez la tarea filosófica del último Ortega: "La idea de principio en Leibniz y la evolución de la teoría deductiva". En este libro, por un lado se examinan las raíces alemanas con especial (...) atención a Fichte y a Heidegger y la teoría del conocimiento que Ortega va diseñando. Por otro, se analiza la estructura textual del libro mientras se profundiza en algunos de los logros más generales de la "segunda navegación" de Ortega, como el tema de "ideas y creencias", el constructivismo cognitivo y la teoría de la historia. En una tercera parte, se incide en diversas consecuencias de la obra de Ortega, en la hermenéutica y en el pensamiento cívico sobre España, así como en la crítica filosófica. (shrink)

Saint Paul's "thorn in the flesh" has been the subject of much controversy in medical, historical and religious literature. It was crucial for the development of Paul's theology and, therefore, its study is important for a better understanding of early Christianity. The purpose of this article is to review the available evidence on this issue, perform a historical and medical critical analysis and suggest plausible diagnosis that have not been previously published in scientific literature. Our research on primary sources seem (...) to indicate that in 41–42 AD Paul of Tarsus developed a clinical picture with a pain similar to that of a thorn injury and bad physical appearance. It could also have a chronic course with a limited number of relapses and few global. It could remind Job’s illness and provoke humiliation in Paul and repulse in his audience. Multiple diseases could explain some of these data, but fewer explain all of them. Though a definitive diagnosis cannot be achieved, we think that cutaneous disorders are the most obvious candidates for a humiliating and painful disease which, however, would permit long journeys during more than a decade. Disorders with cutaneous involvement like lupus erythematosus, dermatomyositis, urticaria/angioedema, leukocytoclastic vasculitis or nodular vasculitis should be added to other possibilities previously reported.

Al momento de indagar sobre la experimentación en Galileo Galilei, es difícil identificar qué tipo de experimentos, efectivamente, realizó.

Building upon the insights of scholars attuned to story, narrative, and myth, this article explores the relationship between myth, science, and religion. After clarifying the interplay of the three terms—story, narrative, and myth—and the preference for the term myth, this article will argue that myth can serve as a medium through which religion, neuroscience, and mental well‐being interact. Such an exploration will cover the role of myths in religion, the neurological basis of myth, and the practices of narrative psychology and (...) bibliotherapy. The article will conclude with suggestions for understanding and utilizing the relationship between myth and the scholarly study of the relationship between science and religion. This article ultimately suggests that myth can operate as a methodological aid to the science‐and‐religion field. (shrink)

This article is a response to Josh Reeves's recent book Against Methodology in Science and Religion: Recent Debates on Rationality and Theology that welcomes Reeves's proposal for an anti‐essentialist future for the field of science‐and‐religion, particularly because it has the potential to move the field beyond current, well‐worn methods: the dominance of Christian theology and doctrine, the importance of credibility strategies, and the dependence upon philosophical discourses. Reeves’ proposal has the potential to open the science‐and‐religion field to other topics, problems, (...) and methods, such as studying lived science‐and‐religion. One way of doing this is to study popular culture and its artifacts such as literature, which portrays a co‐mingling of religion and science at the level of day‐to‐day experiences and practices of characters. For at the level of lived experience, religion and science are not well‐defined disciplines neatly compartmentalized into separate academic departments. (shrink)

The role of academic satisfaction on persistence and successful academic behavior has been the focus of research for decades. Nevertheless, driven by positive educational psychology, subjective well-being has been highlighted as another central feature in the academic path of students. Studies aimed at identifying the variables that contribute to explain different aspects of academic performance have been widely investigated, although studies aimed at identifying the determinants of subjective well-being are still limited. The present paper examined the contribution of AS judgments (...) on subjective well-being. To this end, it was hypothesized that SWB levels depend on the balance between positive/negative emotions and life satisfaction judgments. Furthermore, it was stipulated that AS has an indirect contribution on SWB, through life satisfaction, whereas the balance of emotions influences both AS judgments and life satisfaction. Using an analysis strategy based on structural equation modeling, the results indicated that the model fitted satisfactorily, explaining 32% of the variance of SWB. Particularly, it was observed that AS judgments contributed to life satisfaction judgments. Although no direct contribution of AS on SWB was reported, a total contribution partially mediated by life satisfaction judgments was revealed. These findings support the importance of academic satisfaction judgments, not only because of their importance in academic terms, but also because of their impact on university students’ subjective well-being and health.

Karl Marx (1818-1883) was trained as a philosopher and steeped in the thought of Hegel and German idealism, but turned away from philosophy in his mid-twenties towards politics, economics and history. It is for his these subjects Marx is best known and in which his work and ideas shaped the very nature of the nineteenth and twentieth centuries. However, Marx's engagement with philosophy runs through most of his work, especially in his philosophy of history and in moral and political philosophy. (...) In this outstanding introduction to Marx's philosophy Jaime Edwards and Brian Leiter begin with an overview of Marx's life and intellectual development, before examining and assessing the following important topics: Marx's theory of history: Hegel, dialectics, teleology, materialism functionalism and the causal explanation of historical change economics, history and the transition from communism to capitalism ideology, morality and religion human nature, alienation and the good life for human beings Marx's legacy and influence, including Western Marxism and the Frankfurt School. The addition of chapter summaries, annotated further reading and a glossary of technical terms make this an indispensable introduction to Marx's philosophy. It will also be useful to those in related disciplines such as politics, sociology, history and economics. (shrink)

Resumen Debido a la polisemia que la complejidad exhibe, se pretenden exponer las distintas posturas, definiciones, descripciones y debates acerca de esta, a la luz de lo descrito por Carlos Maldonado, Edgar Morin, Ilya Progogine, Murray Gell-Mann, Leonardo Rodríguez y Julio Aguirre, quienes comportan un principio dialógico y translúcido, que integraría la lógica clásica teniendo en cuenta sus límites de facto y de jure, que además llevaría en sí el principio de la Unitas Multiplex, que escapa a la unidad abstracta (...) por lo alto y por lo bajo. Luego de la presentación de las posturas de los autores mencionados se pasa a describir los encuentros y desencuentros que de estos aparecen sobre este concepto; y finalizar al proponer una definición y caracterización personal de la complejidad.Due to the polysemy of Complexity, it is intended to expose different postures, definitions, descriptions and debates about It, in the light of what was described by Carlos Maldonado, Edgar Morin, Ilya Prigogine, Murray Gell-Mann, Leonardo Rodríguez and Julio Aguirre. For them it implies a dialogical and translucent principle that would integrate classical logic considering its de facto and de jure limits, and that in addition would take in himself the principle of Unitas Multiplex that escapes to the abstract unity by the high and by the low. After the presentation of the positions of the mentioned authors the paper goes on to describe encounters and disagreements about this concept finally proposing a definition and characterization of complexity.

This essay proposes to examine minority literature, and the scandals often associated with it, as a function of economy and choice. Rather than weighing the political strategies of identity and representation available to minority literature, this approach aims to dissect the ways its circulation is conditioned both by the modern liberal principle of self-ownership and by the flexible conversion of value among different economies characteristic of late capitalist forms of recognition. The entanglement of these spheres of value becomes explicit in (...) the moment of choice inherent to scandal, where the political or philosophical questions of minority identity are reduced to a matter of expenditure. Using the insights of Amartya Sen and Jean Baudrillard on the prerogative of choice in the constitution of capitalist subjects, I argue that it can offer a more comprehensive account of the political valence of minority literature, and its scandals, than the hermeneutics of representation.
