In this paper, a stochastic simulation model for a standalone PV system sizing is replicated and extended to supply a dairy’s power demand. A detailed hourly-based simulation is conducted considering an hourly load profile and global solar radiation prediction model. The stochastic simulation model is based on a thorough statistical analysis of the solar radiation data and simulates the energy yield, the excess energy curtailed, and the state of charge of the batteries for the sizing month and the whole year, (...) providing the designer autonomy factor values d to properly size the PV system, finding the optimum combination of installed peak power P m and battery storage capacity C L that meets the application load requirements, considering a preset reliability level at minimum cost. The model makes use of the NASA’S Surface Meteorology and Solar Energy database to obtain solar radiation data. Results show a substantial reduction of 44% in installed peak power and battery storage capacity when compared to conventional methodologies, considering three days of autonomy, and an 85% reduction considering four days. Considering the goodness of fit test results, the Wakeby distribution best represents the behavior of historical solar radiation data for the site in almost half of the months. This article seeks to contribute to the literature gap in the application of methodologies for the multicomponent power supply in the dairy industry through the use of renewable energy. (shrink)

In ”Skepticism,” Peter Klein distinguishes between the “Academic Skeptic” who proposes that we cannot have knowledge of a certain set of propositions and the “Pyrrhonian Skeptic” who refrains from opining about whether we can have knowledge. Klein argues that Academic Skepticism is plausibly supported by a “Closure Principle‐style” argument based on the claim that if x entails y and S has justification for x, then S has justification for y. He turns to contextualism to see if it can contribute to (...) the discussion between one who claims that we can have knowledge about some epistemically interesting class of propositions and the Academic Skeptic. He outlines the background of Pyrrhonian Skepticism, pointing out that the Pyrrhonist withholds assent concerning our knowledge‐bearing status because reason cannot provide an adequate basis for assent. He assesses three possible patterns of reasoning, and concludes that the Pyrrhonist view, that reason cannot resolve matters concerning the nonevident, is vindicated. (shrink)

Este artículo de investigación explora los factores relacionados con el cambio social por la educación en jóvenes en contextos de pobreza y marginación en Veracruz. Para tal efecto, recupera datos del levantamiento de información de un proyecto sobre jóvenes mediante un enfoque cualitativo realizado en ciudades medias de ese estado, en el cual se estudiaba la participación política de los jóvenes, pero el tema educativo era muy importante para comprender las trayectorias juveniles. Nuestro artículo es derivado de la investigación “Promover (...) espacios para la participación cívica, la inclusión y la reducción de la Violencia” patrocinado por el IDRC (Centro Internacional de Investigaciones para el Desarrollo de Canadá). La cual se enfocó en la inclusión social y la ciudadanía de los jóvenes en entornos de violencia, vulnerabilidad y exclusión en el estado de Veracruz. Se llevó a cabo en colaboración con la Universidad Veracruzana, el Centro de Servicios Municipales (CESEM) y el Movimiento de Apoyo a Niños Trabajadores y de la Calle (MATRACA-AC) durante al 2017 al 2020. El levantamiento del proyecto del cual recuperamos datos para este trabajo consistió en 20 grupos focales, 46 entrevistas a jóvenes y 14 a docentes en Xalapa, Coatzacoalcos, Veracruz y Poza Rica ciudades del Estado de Veracruz. Los datos indican que, al menos, existen cinco factores que constriñen los proyectos educativos juveniles: ingreso familiar, aspiraciones, contexto social, redes sociales y apoyo docente. Estos elementos de combinación contingente determinan las trayectorias juveniles individuadas en el campo escolar y pueden explicar tanto la permanencia como el abandono de la escuela en estas ciudades.

The aim of this paper is to provide an approach to the etho-aesthetic dimension in Marcuse’s thought. The approach in this paper is built upon the following thesis: the etho-aesthetic dimension consists of the transformation of subjectivity based on artistic sensitivity and critical rationality from which social relations opposed to an advanced industrial society and its one-dimensional man are reconstructed materially and intellectually. The conclusion is the following: a Marcusian critical theory, inherited from Marx and Schiller, would be one capable (...) of analyzing the potential qualitative changes of the subjects and social institutions to generate a higher level of rational development, equitable in the distribution of resources and in the generation of greater spaces of freedom. Its basis would be an etho-aesthetic attitude that does not take pleasure in squandering, but in the reflective experience of the sensible. (shrink)

Historicist and political reflection of Freire, gives us a deep look promising in the world. His conviction that oppressor and oppressed can liberate each other and together build a more just and equal, is embodied in education as an emancipatory praxis, which must be built into a dialogic relationship between teacher and learner. Paulo Freire's postulates it has influence of diverse intellectual currents and in this tour, we find a permanent invocation to Antonio Gramsci's contributions. La reflexión historicista y política (...) de Freire, nos entrega una mirada profundamente esperanzadora del mundo. Su convicción que opresor y oprimido se pueden liberar mutuamente y en conjunto construir una sociedad más justa e igualitaria, se materializa en la educación como una praxis emancipadora, la cual debe construirse en una relación dialógica entre educador y educando. Los postulados de Paulo Freire tienen influencia de diversas corrientes intelectuales y en ese recorrido, encontramos una permanente invocación a los aportes de Antonio Gramsci. (shrink)

This article presents the results and conclusions of a research study aimed at analyzing the incidence of Colombian criminals’ discourses and other people’s discourses in the configuration of the criminals’ identity, as enunciated in the works of the Colombian author Mario Mendoza and other academic and journalistic narratives. Likewise, identities were studied as discursive signs constructed from social relations; and an explanation was provided for violence and criminality as manifestations of the criminals’ denial of their identities and the rupture of (...) the principle of discourse regulation. The study is based on the theoretical, methodological and interdisciplinary perspective of the Semiotics School of París. It showed that the violent and criminal behavior of the analyzed subjects is guided by a way of life and a narrative scheme that implies a specific configuration of discursive identities. This also involves the encounter with a self ­—oneself and others who are denied—, constant and intense dysphoric manifestations, states of nonsense and senseless that mobilize the destruction of others as representations of an unacceptable self, which tries to resignify and restore with a compensatory violence. In this way, the study seeks to contribute to the understanding of crime in Colombia and its multiple causes. (shrink)

El artículo recorre la obra de Rodolfo Kusch posicionando sus principales propuestas en la construcción de tres enfoques convergentes en su filosofía. El primer enfoque está relacionado con la fenomenología y la cultura. El segundo enfoque se refiere a la influencia de la antropología y el cuestionamiento por el símbolo. El tercer enfoque despliega una aproximación filosófico-política. Estos enfoques permiten introducir tres “horizontes de pregunta” principalmente relacionados con el método, con lo popular y con lo indígena, que son expuestos como (...) asuntos centrales en toda su obra. Estos “horizontes de pregunta” buscan comprender los alcances de la filosofía de Kusch y su contribución al pensamiento filosófico americano. This paper analyses the work of Rodolfo Kusch remarking his main philosophical proposals through three correlated perspectives. The first perspective refers to phenomenology and culture. The second focuses on the influence of anthropology and the problem of symbols. The third posits a political-philosophical approximation. These perspectives operate interdependently as the background for Kusch’s philosophy and allow us to introduce three “questioning horizons” related to the method, the popular and the indigenous as the central issues of his philosophical work. Thus, these “questioning horizons” build a platform to understand Kusch’s philosophy and his contribution to the Latin American philosophy. (shrink)

Bioethics needs an expanded moral vision. It is now time for bioethics to take full account of the problems of health disparities and structural injustice that are made newly urgent by the COVID-19 pandemic and the effects of climate change. Nancy M. P. King, Gail E. Henderson, and Larry R. Churchill make the case for a more social understanding and application of justice, a deeper humility in assessing expertise in bioethics consulting, a broader and more relevant research agenda, and greater (...) appreciation of the profound health implications of global warming.

This article seeks to reconsider some colonial and contemporary readings around a paradigmatic figure: Malintzin. With this objective I will divide our approach into four correlated sections. The first introduces some elements around the construction of the term Malintzin, highlighting those that are related with the Nahua cultural world. The second takes up the colonial chronicles of Bernal Díaz del Castillo and Diego Muñoz Camargo, identifying their specific contents related to her figure. The third delves into some contemporary contributions of (...) a literary, historiographical and philosophical nature. To this purpose I will recover the literary appreciations of Octavio Paz, the historical proposals of Matthew Restall, and the philosophical approach of Bolívar Echeverría. The fourth section functionalizes some final considerations related to Malintzin as useful perspective to problematize the contemporaneity of the conquest of Mexico. Lately, this article seeks to ask and reflect on Malintzin in terms of the construction of an imaginary that posits a multidirectional understanding of her figure. (shrink)

Reseña del libro Filosofía de la inmunología de Thomas Pradeu.

This book views Green's philosophical opus through his public life and political commitments. It demonstrates how his main ethical and political conceptions -- his idea of 'self realisation' and his theory of individuality within community -- were informed by evangelical theology, popular Protestantism and an idea of the English national consciousness as formed by religious conflict. While the significance of Kant and Hegel is acknowledged, it is argued that 'indigenous' qualities of Green's teachings resonated with Victorian Liberal values.

First published in 1982, this reissue contains a critical exposition of the views of Frege, Dedekind and Peano on the foundations of arithmetic. The last quarter of the 19th century witnessed a remarkable growth of interest in the foundations of arithmetic. This work analyses both the reasons for this growth of interest within both mathematics and philosophy and the ways in which this study of the foundations of arithmetic led to new insights in philosophy and striking advances in logic. This (...) historical-critical study provides an excellent introduction to the problems of the philosophy of mathematics - problems which have wide implications for philosophy as a whole. This reissue will appeal to students of both mathematics and philosophy who wish to improve their knowledge of logic. (shrink)

As a preliminary step to beginning to assess the usefulness of clinical vignettes to measure ethical sensitivity in undergraduate medical students, five clinical vignettes with seven to nine ethical issues each were created. The ethical issues in the vignettes were discussed and outlined by an expert panel. One randomly selected vignette was presented to first, second and third year students at the University of Toronto as part of another examination. The students were asked to list the issues presented by the (...) patient problem. Responses from 281 students were obtained. These students identified an average of 2.72 ethical issues per vignette. Each response was classified under the domains of autonomy, beneficence and justice. Comparisons were made between classes and between vignettes. There was considerable variation between classes and the responses to different vignettes seem to indicate that different vignettes measure the various domains in different ways. It does appear that the use of vignettes is one way to measure aspects of ethical sensitivity in medical students but more study is required to clarify exactly what is being measured. (shrink)

An instrument to assess 'ethical sensitivity' has been developed. The instrument presents four clinical vignettes and the respondent is asked to list the ethical issues related to each vignette. The responses are classified, post hoc, into the domains of autonomy, beneficence and justice. This instrument was used in 1990 to assess the ethical sensitivity of students in all four medical classes at the University of Toronto. Ethical sensitivity, as measured by this instrument, is not related to age or grade-point average. (...) Sensitivity increases between the 1st and 2nd year and then decreases throughout the rest of undergraduate medical training, such that the 4th-year students identify fewer issues than those entering medical school. Students expressing a career choice of family medicine identify more issues than their peers. Several problems with the use of the instrument and the interpretation of the data were found. Nonetheless, these findings, if reproducible, are important and their meaning needs further discussion. (shrink)

Engineering is 'the people-serving profession'. The work of engineers involves interaction with clients, other engineers, and the public at large. More than any other profession, their work also directly involves and affects the environment. This book makes the case that engineers have special professional obligations to protect and enhance the environment, and the authors - one, an engineer and the other, a philosopher - seek to provide an ethical basis for these obligations. In exploring these ethical issues, the authors aim (...) to show that engineers make a difference. The text opens with a series of case studies in which engineers face complex and challenging decisions about the environment. Succeeding chapters examine different ideas about environmental ethics for engineers, including professional codes and both modern and historical discussions of environmental responsibility. The book concludes with a collection of readings that complement the text. Students, as well as practising engineers, will find much of interest in this well-argued and thought-provoking book.

Gordon Baker and I had been colleagues at St John’s for almost ten years when we resolved, in 1976, to undertake the task of writing a commentary on Wittgenstein’s Philosophical Investigations. We had been talking about Wittgenstein since 1969, and when we cooperated in writing a long critical notice on the Philosophical Grammar in 1975, we found that working together was mutually instructive, intellectually stimulating and great fun. We thought that we still had much to say about Wittgenstein’s philosophy, and (...) it seemed to us that misinterpretations of passages in the Investigations were so extensive that it would be worth trying to write a detailed analytical commentary. It is difficult to recapture the excitement of those early days in being among the first to work on the microfilms and, subsequently, on the photocopies of Wittgenstein’s Nachlass. We spent many hundreds of hours poring over the typescripts and the often only semi-legible manuscripts, fascinated and privileged to be able to try to follow the development of the thoughts of a great philosophical genius. We talked endlessly about what we had found in Wittgenstein’s manuscripts and typescripts, and debated how it should be understood. The first fruit of our labours was Wittgenstein – Understanding and Meaning. Its guiding idea was to draw attention to the manner in which Wittgenstein linked the concepts of meaning, understanding and explanation, and so to bypass the connections between meaning, truth and truth-conditions that so fascinated philosophers of the 1970s, and to abandon the red-herring of assertion-conditions and anti-realism. After a hiatus of four years, during which time we wrote a controversial book entitled Frege – Logical Excavations and a polemical book on contemporary philosophy of language – Language, Sense.

Differential scanning calorimetry (DSC) has been employed to investigate the glass transition activation energy E g, thermal stability and glass-forming ability (GFA) of Se90In10− x Sb x (x = 0, 2, 4, 6, 8, 10) chalcogenide glasses. DSC runs were performed at six different heating rates. Well-defined endothermic and exothermic peaks were obtained at glass transition and crystallization temperature. The dependence of glass transition temperature T g on heating rate (α), as well as composition of Sb, has been studied. From (...) the dependence of glass transition temperature on heating rate, the E g has been calculated on the basis of the Kissinger [Anal. Chem. 29 (1957) p.1702] and Moynihan [J. Phys. Chem. 78 (1974) p.267] models. Thermal stability has been monitored through the calculation of temperature differences T c–T g, the stability parameter S, and the enthalpy released during crystallization H c. The GFA has been investigated on the basis of the Hruby parameter H r, which is strong indicator of GFA. Results for GFA are in good agreement with fragility index F i calculations, indicating that Se90In6Sb4 is an excellent glass-former. (shrink)

This article aims to read feminist new materialisms (Barad), together with ‘postulated’ linguistic or cultural primacy of Queer Theory (Butler), to show how both are engaged in similar critical-ethical endeavours. The central argument is that the criticism of Barad and new materialisms misses Butler’s materialistic insights due to a narrow interpretation of Butler's alleged social-constructivist position. There is, therefore, a specific focus on where they both make similar ethical appeals. Moreover, the article relies on Adorno's negative dialectic to highlight an (...) interpretation of Barad and Butler as being part of the same dialectical movement, in which materialism and idealism fluctuate in their mutual criticisms, thus continuing the procession towards 'new knowledge' and emancipation, or freedom, through their motions back and forth.

This study of T.H. Green views his philosophical opus through his public life and political commitments, and it uses biography as a lens through which to examine Victorian political culture and its moral climate. The book deals with the political and religious history of Victorian Britain in examining the basis of Green's Liberal partisanship. It demonstrates how his main ethical and political conceptions—his idea of "self-realisation" and his theory of individuality within community—were informed by evangelical theology, popular Protestantism and an (...) idea of the English national consciousness as formed by religious conflict. While the significance of Kantian and Hegelian elements in Green’s thought is acknowledged, it is argued that “indigenous” qualities of Green’s teachings resonated with values shared alike by elite and rank-and-file Liberals during the mid and late Victorian era. In examining Green’s beliefs about the historical evolution of English liberty, his championing of Nonconformity and Nonconformist causes and his approval of religious bases of community, this study analyzes the ripening of a Greenian moment and traces Green’s influence on Liberal, quasi-socialist and Conservative social reform down to the 1920s. The lasting impact of Green’s teachings on British and Western political philosophy, apparent in the current vogue for communitarianism in liberal theory, indicates limitations of the “secularization thesis” still tacitly accepted by historians of Western political thought.
