Copyright © 2015 by ASME.This paper uses path synthesis techniques to design four-bar linkage modules to constrain the movement of a 3R chain. The result is a 10-bar linkage. The goal is to develop a design procedure for a robotic system that guides the human leg during the walking gait cycle. A 3R chain is designed to match the dimensions of a human leg and the two four-bar linkages are synthesized using 9 point path synthesis to constrain the trajectory of (...) the ankle and the toe. Precision points are derived from a basis spline equation. A numerical example is given using data collected from a motion capture system. (shrink)

Travelling internationally to acquire medical treatments otherwise unavailable or inaccessible in one’s home country is not a novel concept. Conventionally, such medical travel largely entailed patients from developed countries or wealthy patients from the developing world seeking care in Western facilities like the Mayo Clinic in the U.S. and myriad private clinics along Harley Street in London, England. What is different about the topical phenomenon known as “medical tourism” is the growing trend of health services export in the opposite direction. (...) The number of patients travelling from the developed world to low- and middle-income countries for treatments has ballooned in recent years, primarily driven by difficulties with accessing affordable care at home. According to a liberal estimate by the Deloitte Center for Health Solutions, the number of Americans travelling abroad for care rose from 750,000 in 2007 to 1.6 million in 2012. On the flip side, Thailand reportedly treated a total of 1.3 million foreign nationals in 2007, which represented a 16% leap from 2001. (shrink)

While "A needs X" often calls for supplementation by the Y X is needed for, Thomson, Wiggins and Braybrooke have argued that there is a sense of "need" for which this is unnecessary. But Gricean conventions for conversation allow us to use ellipsis in a unified account of "need" while explaining the data Thomson and Wiggins appeal to: nondetatchment of bare needs from more fully specified ones, avoidance of serious harm as a default filling of the Y-slot, and the apparent (...) normativeness of some need-statements. Their detailed discussions also undermine the utility of demarcating a sense of "fundamental" need. (shrink)

En este ambicioso libro, el biólogo Daniel W. McShea y el filósofo de la biología Robert N. Brandon desafían las explicaciones explícitas encontradas en la litera-tura acerca del origen de la diversidad y la complejidad en los seres vivos. Estas explicaciones recurren en su mayoría a la acción de la selección natural, como ser, a la selección diversificadora/disruptiva, a la selección de niveles superiores favoreciendo a especies/clados con mayor propensión a la especiación, o a las ventajas de una mayor (...) división del trabajo, entre otras alternativas (p. 1). Si bien estas explicaciones pueden ser correctas, no constituirían toda la historia, según los autores, pues habría una tendencia de fondo no reconocida en la literatura (pero invocada en las explicaciones de casos concretos) hacia un aumento de la diversidad y la complejidad. Esta tendencia surgiría simplemente de que las variaciones azarosas, cuando se heredan, se acumulan en diferentes direcciones en diferentes poblaciones, con el resultado de que la diversidad se incrementa. Para expresar esta tendencia, los autores proponen una ley, que denominan ZFEL (por zero-force evolutionary law) y que formulan de la siguiente manera: “En cualquier sistema evolutivo en el que hay variación azarosa y he-rencia, en ausencia de fuerzas y constricciones, la diversidad y la complejidad tenderán a aumentar” (p. 4).

Using the corpus of JSTOR articles, we investigate the role of gender in collaboration patterns across the scholarly landscape by analyzing gender-based homophily--the tendency for researchers to co-author with individuals of the same gender. For a nuanced analysis of gender homophily, we develop methodology necessitated by the fact that the data comprises heterogeneous sub-disciplines and that not all authorships are exchangeable. In particular, we distinguish three components of gender homophily in collaborations: a structural component that is due to demographics and (...) non-gendered authorship norms of a scholarly community, a compositional component which is driven by varying gender representation across sub-disciplines, and a behavioral component which we define as the remainder of observed homophily after its structural and compositional components have been taken into account. Using minimal modeling assumptions, we measure and test for behavioral homophily. We find that significant behavioral homophily can be detected across the JSTOR corpus and show that this finding is robust to missing gender indicators in our data. In a secondary analysis, we show that the proportion of female representation in a field is positively associated with significant behavioral homophily. (shrink)

Postmodernism is considered as the historical stage of the transition of contemporary society from mature industrial capitalism to the qualitatively new technological and social production order. The real transformations of contemporary society’s factors have been brought into the correlation with the production changes that determine transition from Modern Age machine technologies to nanotechnologies. Existence of Postmodern society is presented as the borderland of historical ages, that is, as the period of the fading away of the Modern Age social forms and (...) of the becoming of social activity’s new forms that are specific for the new age of the development of society and of the worldwide socionatural entity. The author analyzes theoretical and worldview potential of Postmodern philosophy and its inability to represent further postindustrial society evolution tendencies. Possible scenarios of Рostmodern society evolution are considered in the context of contemporary concepts on the changes in the human role in nature and society as well as in the context of the trends of socionatural Universe development. The paper reveals technical, technological and social presuppositions of the transition from the nature-historical stage of society development to the true historical stage of human development.

Excerpt from Meditaciones del Quijote: Meditación Preliminar, Meditación Primera Nada que de éste provenga puede ser nos simpático. El rencor es una emana ción de la conciencia de inferioridad. Es la supresión imaginaria de quien no pode mos con nuestras propias fuerzas real mente suprimir. Lleva en nuestra fantasía aquel por quien sentimos rencor, el aspec to lívido de un cadáver; lo hemos matado, aniquilado con la intención. Y luego al ha llarlo en la realidad firme y tranquilo, nos parece (...) un muerto indócil, más fuerte que nuestros poderes, cuya existencia signi fica la burla personificada, el desdén vi viente hacia nuestra débil condición.

La presente versión del tratado De Bono Habitu Liber o El libro sobre la buena condición, de Galeno de Pérgamo, se presenta al lector de habla hispana como un acercamiento a la prolífca obra flosófca de quien fuera reconocido en su época como un notable médico anatomista y físico. Los argumentos expuestos por el autor acerca de la ‘buena condición’ dan cuenta de la infuencia retórica de Platón y Aristóteles, al mismo tiempo, de las enseñanzas médicas de Hipócrates. Junto al (...) texto original y la traducción al español, se ofrece una versión en latín empleada en el proceso de traducción como un apoyo para resolver las difcultades textuales y léxicas que presentaba el texto griego, al permitir confrontar una recepción medieval del tratado.

This is the first book-length study of the conception of emotions in premodern, or more specifically, pre-Han Chinese philosophical traditions, ranging from the early-5th to the late-3rd centuries BCE. This era is known as the "Warring States period" in China and marked by the flourishing of a number of different schools of philosophers who advocated their visions of how society should be run. The author looks at wide-ranging views about the nature of emotions and their proper role in moral life (...) espoused by representative thinkers of the time. The approach taken by the author is based on a premise that what constitutes emotions as phenomena in the world is of primary importance to questions concerning the... (shrink)

En un libro reciente McShea y Brandon defienden que la diversidad y la complejidad de la vida se explican, principalmente, por la acción de un principio que llaman “la ley evolutiva de fuerzas cero” o “ZFEL”. Tal principio actuaría de un modo implícito por detrás de muchas explicaciones de la biología, pero nunca habría sido explicitado. Asumiendo que esta idea es interesante, y que los autores en cuestión tienen razón, discutiremos el modo metateórico en que presentan dicho principio, como (...) siendo parte de la teoría de la probabilidad. Esto permite a los autores afirmar que la teoría de la probabilidad brindaría la base reductiva para toda la biología evolutiva (dado que consideran que otros principios, como el de selección natural, también serían parte de la teoría de la probabilidad). Defenderemos que, efectivamente, ZFEL no es propio de la biología únicamente, pero no por formar parte de la teoría de la probabilidad, sino por tratarse de una versión específica del principio de causa común. -/- In a recent book, McShea and Brandon argue that the observed diversity and complexity of life are explainable by a principle they call the “zero-force evolutionary law” or “ZFEL”. Although this principle would be implicit in many explanations given by biologists, it would have never been made explicit. Assuming that this idea is interesting, and that the authors are right, we will discuss the metatheoretical way in which they present said principle, as being a part of probability theory. This allows the authors to claim that probability theory provides the reductive basis for all evolutionary biology. We will defend, in accordance with them, that ZFEL is not a solely biological principle, but not because it is a part of probability theory, but rather because it is a specific version of the principle of common cause.

Ben-Israel and Vaidman have raised objections to my arguments that there are cases where a quantum mechanical weak value can be said not to represent the system to which it pertains. They are correct in pointing out that some of my conclusions were too general. However, for weak values of projection operators my conclusions still stand.
