I. INTRODUCTIONThe Parshall Flume, which was invented in 1920 by R. Parshall, is mostly used in wastewater and crop supply. Utilizing equations, Parshall established dimensions that fit the design, one of the advantages is the conversion of position energy to velocity energy since in other measurement structures there are minimum energy losses in this one it does not allow sedimentation. The structuring of the project is adhered to by different models that define its behavior and limit its use. This is (...) the case of an approach length of the channel entrance, which is nothing more than a primary distance for the action of the flow within the channel. Throughout history, some studies were conducted in an attempt to establish an approximate and realistic value of the length at the time of measurements, but the theories put forward were lost. Some people link this length with the narrowing of the gorge, and others suggest flow conditions before entering the flume. For the development of the project established with its respective objectives, the respective structuring was carried out: For the measurement, the points already established in the field will be taken with the help of a total station, GPS, to verify the respective measurements of the Parshall flume. For the calculations and the design, the points will be introduced in the civil 3D to be able to verify if the points taken are the correct ones and what distances they have between them, through this, we can apply different methods to be able to verify the design that has this Parshall flume. For the evaluation and layout of the gutter, if it is the case, we will carry out a layout in plan with the data already calculated in the office and we will evaluate the situation in which it is so that we can apply a possible solution so that a defect does not occur. In this report, we focus on the design and redesign of a hydraulic irrigation channel where we find a Parshall section, which has the function of measuring the flow found in that section. The measurements found in the field can be verified in the office using formulas and software to verify if the data are correct, if so we can say that it is well designed, otherwise we will look for a possible solution by doing a field study.

Background: Heart rate variability (HRV) has been considered as a measure of heart-brain interaction and autonomic modulation, and it is modified by cognitive and attentional tasks. In cognitive tasks, HRV was reduced in participants who achieved worse results. This could indicate the possibility of HRV predicting cognitive performance, but this association is still unclear in a high cognitive load sport such as chess Objective: To analyse modifications on HRV and subjective perception of stress, difficulty and complexity in different chess problem (...) tasks. Design: HRV was assessed at baseline. During the chess problems, HRV was also monitored, and immediately after chess problems the subjective stress, difficulty and complexity were also registered. Method: A total of 16 male chess players, age: 35.19 (13.44) and ELO: 1927.69 (167.78) were analysed while six chess problem solving tasks with different level of difficulty were conducted (two low level, two medium level and two high level chess problems). Participants were classified according to their results into two groups: high performance or low performance. Results: Friedman test showed a significant effect of tasks in HRV indexes and perceived difficulty, stress and complexity in both high and low performance groups. A decrease in HRV was observed in both groups when chess problems difficulty increased. In addition, HRV was significantly higher in the high performance group than in the low performance group during chess problems. Conclusions: An increase in autonomic modulation was observed to meet the cognitive demands of the problems, being higher while the difficulty of the tasks increased. Non-linear HRV indexes seem to be more reactive to tasks difficulty, being an interesting and useful tool in chess training. (shrink)

El objetivo del presente estudio es analizar algunos aspectos vinculados a la interpretación de la ley humana y su causa final en el pensamiento del teólogo, f ilósofo y jurista Español Francisco Suárez (1548-1617). En algunos autores resulta indudable su pertenencia a un modo de pensar determinado. Ello se observa, por mencionar algunos ejemplos, en los casos de Alberto Magno y Tomás de Aquino —identiicados con la edad media—. Por el contrario otros autores, aún medievales, desarrollaron doctrinas que se (...) constituyeron en preludio de elaboraciones posteriores modernas. Por este motivo tales figuras resultan fuertemente vinculadas a al- gunas corrientes de pensamiento modernas. Aquí puede mencionarse a Escoto, Ockham y Marsilio de Padua. Esta claridad recientemente señalada no se observa en relación a Francisco Suárez quien aparece como un autor controvertido y considerado de transición, por lo menos temporalmente, entre edad media y moderna. Las discusiones actuales en torno a Suárez se deben a la inexistencia de un cierto consenso respecto al lugar que le corresponde a su doctrina, especialmente filosófico-política, entre las concepciones que caracterizan a los períodos antiguo-medieval y moderno. Por estos motivos esta investigación persigue def inir la ubicación del pensamiento suareciano, en relación al tema propuesto, y de acuerdo a lo que nuestro autor expone en su Tratado de la Ley.

Es a todas luces evidente que los cambios globales de las últimas décadas, connotados entre otras cuestiones por el desplazamiento masivo de personas y la consolidación de identidades nacionales más borrosas y cambiantes, han repercutido de una manera significativa sobre el mundo académico, con la consecuente renovación de sus intereses. El auge adquirido por el estudio del exilio en América latina forma parte de esta nueva realidad. A la diversificación temática y aparición de nuevos y más sofisticados enfoques se han (...) sumado numerosos congresos y jornadas de estudio y debate, una importante cantidad de libros y artículos y la consolidación de grupos y redes de investigación internacionales. La publicación de Exile, Diaspora and Return es una prueba de este auge. Representa una excelente puesta al día de los alcances y sutileza de los estudios más recientes, a la vez que da cuenta de las decisivas vinculaciones de la cuestión con temas amplios como la globalización, los cambios en la idea de ciudadanía o las transiciones democráticas...

Francisco de Miranda (1750-1816), militar, viajero ilustrado, y, sobre todo, precursor de la independencia latinoamericana, ha sido objeto de numerosos estudios biográficos centrados fundamentalmente en su vida azarosa y aventurera. Sin embargo, su periplo intelectual ha sido investigado en un grado mucho menor, sobre todo en lo que se refiere a su meditación constitucional. El presente artículo tiene como fin, precisamente el de estudiar la relación de su pensamiento con la actuación política que le condujofinalmente a convertirse en Generalísimo de (...) la república de Venezuela en el año 1812, llegando a concentrar poderes excepcionales para hacer frente a la metrópoli española. De resultas de tal investigación puede concluirse que Miranda hizo una lectura de diversos autores ilustrados conocidos en Europa y el Nuevo Mundo, pero que también extrajo distintas reflexiones de su propia experiencia política por haber tomado parte en las dos grandes revoluciones del siglo XVIII.

Los Estados Unidos de América no emergieron como una auténtica nación con sólidas instituciones estatales hasta bien entrado el siglo XIX, pese a compartir una cultura común. La estructura conf igurada inicialmente para sostener su vínculo político fue el foedus o alianza entre Estados del Derecho de gentes, y el objetivo de este trabajo es precisar en qué medida influiría en la articulación constitucional de la joven república, desde su proclamación de la independencia hasta la Convención de Filadelf ia de (...) 1787. Para ello se examina la influencia de pensadores como Vattel, Montesquieu o Pufendorf en los colonos americanos y se expone el conflicto entre unos y otros Estados de la Unión. El resultado del estudio apunta a que la fórmula federativa que le permitió a la república ser reconocida por las naciones europeas le sirvió también para aplazar sus conflictos internos, y de modo muy especial el referente a la esclavitud, merced a una dinámica territorial de carácter expansivo.

As the premier early modern advocate of an Epicurean alternative to the prevailing neo-Scholastic framework of Aristotelianism, Pierre Gassendi promoted not only ancient but also innovative reasoning on behalf of atomism, probabilism, empiricism, psychological hedonism, social contractarianism, and a range of other stances associated with the philosophy of the Garden. Much commentary has focused on the extent to which Gassendi ‘baptizes’ Epicurean thought. Beyond this aspect of his Epicureanism are questions as to whether, and how, Gassendi is true to core (...) Epicurean thinking, and what he preserves and promotes as valuable to philosophical and natural investigations of his time. Indeed, much subsequent modern philosophy builds on or reacts to an Epicurean legacy bequeathed by Gassendi, comprising his adjustments to, constraints on, or corrections of, the canonical views. Yet, for all his amendments, he retains as a primary philosophical motivation the Epicurean goal of striving for ataraxia. In this, he signals his firm commitment to philosophy in the tradition of the canonical Epicurean views. And, as with Epicurus’ own notion, his account of the centrality of attaining tranquility directs us to a better understanding of our nature and that of the world around us; amenable, in Gassendi’s framework, to Christian thought and contemporary natural philosophical investigations.

In this book Saul Kripke brings his powerful philosophical intelligence to bear on Wittgenstein's analysis of the notion of following a rule.

Reference and Existence, Saul Kripke's John Locke Lectures for 1973, can be read as a sequel to his classic Naming and Necessity. It confronts important issues left open in that work -- among them, the semantics of proper names and natural kind terms as they occur in fiction and in myth; negative existential statements; the ontology of fiction and myth. In treating these questions, he makes a number of methodological observations that go beyond the framework of his earlier book -- (...) including the striking claim that fiction cannot provide a test for theories of reference and naming. In addition, these lectures provide a glimpse into the transition to the pragmatics of singular reference that dominated his influential paper, " Speaker's Reference and Semantic Reference " -- a paper that helped reorient linguistic and philosophical semantics. Some of the themes have been worked out in later writings by other philosophers -- many influenced by typescripts of the lectures in circulation -- but none have approached the careful, systematic treatment provided here. The virtuosity of Naming and Necessity -- the colloquial ease of the tone, the dazzling, on-the-spot formulations, the logical structure of the overall view gradually emerging over the course of the lectures -- is on display here as well.

Albert and De Ruiter provide an introduction to the Conversation Analytic approach to ‘repair’: the ways in which people detect and deal with troubles in speaking, hearing and understanding in conversation. They explain the basic turn‐taking structures involved, provide examples, explain recent developments in the field and highlight some important points of contact and contrast with work in the Cognitive Sciences.

Saul Smilansky presents an original new approach to the problem of free will, which lies at the heart of morality and self-understanding. He maintains that the key to the problem is the role played by illusion. Smilansky boldly claims that we could not live adequately with a complete awareness of the truth about human freedom and that illusion lies at the center of the human condition.

O presente artigo tem como objetivo investigar quais as diferenças epistêmicas entre a Fenomenologia do Espírito de Hegel e a Fenomenologia Pura de Husserl, possibilitando um comparativo de qual a relação entre a consciência de Deus nas possibilidades fenomenológicas. Inicialmente, o artigo se constitui pelos conceitos relacionados hegelianamente, que compõem a dimensão teológica de Hegel, realizando aprofundamento no modo como a consciência religiosa se presentifica e é vivida. Consequentemente, é abordado quais as questões essenciais que constituem a plataforma da fenomenologia (...) pura, como um ponto de partida apresentasse a intencionalidade e a epoché. Como conclusão, nota-se que o que constitui desvio significativo em cada fenomenologia é em Hegel o conceito de Deus e em Husserl o conceito de intencionalidade. (shrink)

Any plausibly just market exchange must balance two conflicting moral considerations: non-worseness (Wertheimer, 1999) and euvoluntariness (true voluntariness; Munger, 2011). We propose an analytical theory of just market exchange that partly resolves this conflict.

Why is it that the modern conception of literature begins with one of the worst writers of the philosophical tradition? Such is the paradoxical question that lies at the heart of Jean-Luc Nancy's highly original and now-classic study of the role of language in the critical philosophy of Kant. While Kant did not turn his attention very often to the philosophy of language, Nancy demonstrates to what extent he was anything but oblivious to it. He shows, in fact, that the (...) question of _philosophical style_, of how to write critical philosophy, goes to the core of Kant's attempt to articulate the limits, once and for all, that would establish human reason in its autonomy and freedom. He also shows how this properly philosophical program, the very pinnacle of the Enlightenment, leads Kant to posit literature as its other by way of what is here called the _syncope_, and how this other of philosophy, entirely its product, cannot be said to exist outside of metaphysics in its accomplishment. This subtle, unprecedented reading of Kant demonstrates the continued importance of reflection on the relation between philosophy and literature, indeed, why any commitment to Enlightenment must consider and confront this partition anew.

In a wide-ranging, provocative anatomy of modern society and its origins, novelist and historian John Ralston Saul explores the reason for our deepening sense of crisis and confusion. Throughout the Western world we talk endlessly of individual freedom, yet Saul shows that there has never before been such pressure for conformity. Our business leaders describe themselves as capitalists, yet most are corporate employees and financial speculators. We are obsessed with competition, yet the single largest item of international trade is a (...) subsidized market in armaments. We call our governments democracies, yet few of us participate in politics. We complain about "invasive government," yet our legal, educational, financial, social, cultural and legislative systems are breaking down. While most observers view these problems separately, Saul demonstrates that they are largely manifestations of our blind faith in the value of reason. Over the last 400 years, our "rational elites" have gradually instituted reforms in every phase of social life. But Saul shows that they have also been responsible for most of the difficulties and violence of the same period. This paradox arises from a simple truth which our elites deny: far from being a moral force, reason is no more than an administrative method. Their denial has helped to turn the modern West into a vast, incomprehensible, directionless machine, run by process-minded experts - "Voltaire's bastards"--Whose cult of scientific management is bereft of both sense and morality. Whether in politics, art, business, the military, entertainment, science, finance, academia or journalism, these experts share the same outlook and methods. The result, Saul maintains, is a civilization of immense technological power whose peoples increasingly dwell in a world of illusion. Already known to millions of readers as the author of novels which portray the overwhelming effects of this power on the modern individual by weaving together international finance, the oil and arms business, guerrilla warfare, drug traffic, and the world of art, here Saul lays aside the mask of fiction to speak in his own voice. Only by withdrawing from our addiction to "solutions," he argues, reclaiming the citizens' right to question and participate in public life, and recovering a common sense capacity for intelligent panic, can we find a way out of our permanent crisis.

Purpose This paper aims to examine whether companies engaging in corporate philanthropy, a component of corporate social responsibility, disclose information about such activities publicly on their websites, analyze whether there is a relation between the kind of charitable giving, the number of donation types, or the industry sector the company belongs to, the mention on the company website and whether there is a relation between communicate company corporate philanthropy and communicate other company CSR issues. Design/methodology/approach The research methodology was descriptive (...) statistics research method. The data were collected during the months of June and July 2013 from the websites of 141 companies that had recently engaged in corporate philanthropy. Findings The study found that, surprisingly, a considerable portion of companies practicing corporate philanthropy do not disclose that information on their websites. This was especially the case when donations were made with product instead of in cash. Originality/value This study quantifies the fact that many companies engage in CSR through corporate philanthropy but do not communicate those activities to a wider public. This can be seen as a missed opportunity to take advantage of a variety of positive effects that companies related to CSR benefit from. On the other hand, it can also be interpreted as a missed opportunity for the NGOs to encourage their donors to “come out” with their philanthropic activities. (shrink)

Mathematics is a critical part of much scientific research. Physics in particular weaves math extensively into its instruction beginning in high school. Despite much research on the learning of both physics and math, the problem of how to effectively include math in physics in a way that reaches most students remains unsolved. In this paper, we suggest that a fundamental issue has received insufficient exploration: the fact that in science, we don’t just use math, we make meaning with it in (...) a different way than mathematicians do. In this reflective essay, we explore math as a language and consider the language of math in physics through the lens of cognitive linguistics. We begin by offering a number of examples that show how the use of math in physics differs from the use of math as typically found in math classes. We then explore basic concepts in cognitive semantics to show how humans make meaning with language in general. The critical elements are the roles of embodied cognition and interpretation in context. Then, we show how a theoretical framework commonly used in physics education research, resources, is coherent with and extends the ideas of cognitive semantics by connecting embodiment to phenomenological primitives and contextual interpretation to the dynamics of meaning-making with conceptual resources, epistemological resources, and affect. We present these ideas with illustrative case studies of students working on physics problems with math and demonstrate the dynamical nature of student reasoning with math in physics. We conclude with some thoughts about the implications for instruction. (shrink)

Philosophers of language have long recognized that in opaque contexts, such as those involving propositional attitude reports, substitution of co-referring names may not preserve truth value. For example, the name ‘Clark Kent’ cannot be substituted for ‘Superman’ in a context like:1. Lois believes that Superman can flywithout a change in truth value. In an earlier paper, Jennifer Saul demonstrated that substitution failure could also occur in ‘simple sentences’ where none of the ordinary opacity-producing conditions existed, such as:2. Superman leaps more (...) tall buildings than Clark Kent does.Accounts focusing on opacity were unable to explain our ‘anti-substitution intuitions’ in such cases.In Simple Sentences, Substitution, and Intuitions, Saul extends her earlier work. She provides a comprehensive presentation and criticism of recent accounts of simple sentence substitution failure, and proposes a new approach drawing on psychological evidence about cognitive processing. Saul's purpose is not merely to solve the substitution puzzle cases, but to make …. (shrink)

Against recent work by Haslanger and Leslie, I argue that we do not yet have good reason to think that we should single out generics about social groups out as peculiarly destructive, or that we should strive to eradicate them from our usage. Indeed, I suggest they continue to serve a very valuable purpose and we should not rush to condemn them.

Archaea are microorganisms that are distinct from bacteria and eukaryotes. They are prevalent in extreme environments, and yet found in most ecosystems. They are a natural component of the microbiota of most, if not all, humans and other animals. Despite their ubiquity and close association with humans, animals and plants, no pathogenic archaea have been identified. Because no archaeal pathogens have yet been identified, there is a general assumption that archaeal pathogens do not exist. This review examines whether this is (...) a good assumption by investigating the potential for archaea to be or become pathogens. This is achieved by addressing: the diversity of archaea versus known pathogens, opportunities for archaea to demonstrate pathogenicity and be detected as pathogens, reports linking archaea with disease, and immune responses to archaea. In addition, molecular and genomic data are examined for the presence of systems utilised in pathogenesis. The view of this report is that, although archaea can presently be described as non‐pathogenic, they have the potential to be (discovered as) pathogens. The present optimistic view that there are no archaeal pathogens is tainted by a severe lack of relevant knowledge, which may have important consequences in the future.

What shape can radical politics take today in a time abandoned by the great revolutionary projects of the past? In light of recent uprisings around the world against the neoliberal capitalist order, Saul Newman argues that anarchism - or as he calls it postanarchism - forms our contemporary political horizon. In this book, Newman develops an original political theory of postanarchism; a form of anti-authoritarian politics which starts, rather than finishes, with anarchy. He does this by asking four central questions: (...) who are we as subjects; how do we resist; what is our relationship to violence; and, why do we obey? By drawing on a range of heterodox thinkers including La Boétie, Sorel, Benjamin, Stirner and Foucault, the author not only investigates the current conditions for radical political thought and action, but proposes a new form of politics based on what he calls ontological anarchy and the desire for autonomous life. Rather than seeking revolutionary emancipation or political hegemony, we should affirm instead the non-existence of power and the ever-present possibilities of freedom. As the tectonic plates of our time are shifting, revealing the nihilism and emptiness of our political and economic order, postanarchisms disdain for power in all its forms offers us genuine emancipatory potential.

Ubico indicios de mitos nacionales analizando obras narrativas (de Borges y algunos otros autores), y dichos acerca de Borges, centrándome en cómo se verifica, en la narrativa de Borges, (y también en sus intervenciones públicas y en lo que se dice sobre su figura) la irrupción del peronismo. Propongo un cambio de escala: sin intentar interpretar los grandes momentos constitutivos entendiéndolos como mitos de origen, intento constituir series, de características cuasi-míticas, a partir de poner en relación a breves sintagmas que (...) se reiteran en distintas unidades narrativas. Elementos transversales, que van de un relato a otro. Sintagmas que se analizan tomando al conjunto de la obra de Borges como paradigma, y no sólo relatos aislados. En primer término, exploro ciertas constantes en algunos relatos del período 1945-54. Luego me detengo en una serie de versiones contemporáneas sobre un Borges ciego a quien un joven peronista ayuda a cruzar la calle. En tercer lugar. el tema de la aparición de relatos oníricos, literariamente enunciados, sobre personas con garra de pájaro, vinculándolos a los dilemas morales de la élite intelectual en los tiempos del primer peronismo. En tanto estos conjuntos tienen mucho en común con los mitos al ser reelaboraciones sucesivas de un elemento narrativo, podrían ser abordadas con métodos de análisis míticos propios de la antropología estructural. No obstante, el material utilizado tiene diferencias con las mitologías clásicas: a) tiene versiones orales, pero también escritas; b) hechos ficcionales, pero también históricos; c) admiten un orden cronológico verificable. Por lo tanto, arriesgo aquí una exploración metodológica y teórica más bien experimental, aunque deudora de Lévi-Strauss. Concluyo que en estos dos conjuntos se verifica el funcionamiento un sistema ideológico, que es el de la formación nacional argentina, con sus tensiones y crisis. (shrink)

For more than a century the notion of a pre-established harmony between the mathematical and physical sciences has played an important role not only in the rhetoric of mathematicians and theoretical physicists, but also as a doctrine guiding much of their research. Strongly mathematized branches of physics, such as the vortex theory of atoms popular in Victorian Britain, were not unknown in the nineteenth century, but it was only in the environment of fin-de-siècle Germany that the idea of a pre-established (...) harmony really took off and became part of the mathematicians’ ideology. Important historical figures were in this respect David Hilbert, Hermann Minkowski and, somewhat later, Albert Einstein. Roughly similar ideas can be found also among British theorists, among whom Arthur Eddington, Arthur Milne, and Paul Dirac are singled out. Although largely limited to the period 1870–1940, the paper also considers Max Tegmark’s recent hypothesis of the universe being a one-to-one reflection of mathematical structures. (shrink)

In physics education, equations are commonly seen as calculation tools to solve problems or as concise descriptions of experimental regularities. In physical science, however, equations often play a much more important role associated with the formulation of theories to provide explanations for physical phenomena. In order to overcome this inconsistency, one crucial step is to improve physics teacher education. In this work, we describe the structure of a course that was given to physics teacher students at the end of their (...) master’s degree in two European universities. The course had two main goals: To investigate the complex interplay between physics and mathematics from a historical and philosophical perspective and To expand students’ repertoire of explanations regarding possible ways to derive certain school-relevant equations. A qualitative analysis on a case study basis was conducted to investigate the learning outcomes of the course. Here, we focus on the comparative analysis of two students who had considerably different views of the math-physics interplay in the beginning of the course. Our general results point to important changes on some of the students’ views on the role of mathematics in physics, an increase in the participants’ awareness of the difficulties faced by learners to understand physics equations and a broadening in the students’ repertoire to answer “Why?” questions formulated to equations. Based on this analysis, further implications for physics teacher education are derived. (shrink)

Microbial genome sequencing has entered a new phase, where DNA sequence information is gathered from entire microbial communities (metagenomics or environmental genomics) rather than from individual microorganisms. By providing access to the genetic material of vast numbers of organisms, most of which are organisms that have never been isolated or cultivated, a new level of insight is being gained into the diversity and extent of the microbial processes that are presently occuring in environmental communities. By extending metagenomic‐based approaches to the (...) study of very complex and methodologically recalcitrant soil environments, a recent study has found that ammonia‐oxidizing archaea are more abundant in many soils than bacteria.1 These findings not only highlight the undoubtedly critical yet unknown roles that archaea play in global nutrient cycles but illustrate the importance of genomic studies for informing us about the functional capacity of life on Earth.

In its comparison of anarchist and poststructuralist thought, From Bakunin to Lacan contends that the most pressing political problem we face today is the proliferation and intensification of power. Saul Newman targets the tendency of radical political theories and movements to reaffirm power and authority, in different guises, in their very attempt to overcome it. In his examination of thinkers such as Bakunin, Lacan, Stirner, and Foucault Newman explores important epistemological, ontological, and political questions: Is the essential human subject the (...) point of departure from which power and authority can be opposed? Or, is the humanist subject itself a site of domination that must be unmasked? As it deftly charts this debate's paths of emergence in political thought, the book illustrates how the question of essential identities defines and re-defines the limits and possibilities of radical politics today.

We uncover fundamental dimensions of the process through which organizations embed the practice of fraternity through embarking on an organizational journey in the direction of the common good. Building on the latest encyclical of Pope Francis, _Fratelli Tutti_, about fraternal and social friendship, we offer insight into the understanding of what it means to become a fraternal organization and reflect on the key ethical and paradoxical challenges for organizations aiming at collectively contributing to the common good. We add to previous (...) work by characterizing this journey as a process involving unique ethical challenges that emerge from the paradoxes associated with this process and how this might change the nature of the relationships between organizations and others within the organizational landscape.

Epistemology is in the business of formulating norms of acceptable belief. We typically arrive at beliefs through inference. So epistemology is concerned with our inferential practices. Making inferences is something individuals do. If I believe the premises of an argument and you know how to infer something from those premises, it doesn't follow that you will draw the inference, unless you believe the premises. It appears, then, that all the important epistemic work goes on in individual agents. When we build (...) an automobile together, we build it just once, but when we draw the same conclusion, each of us draws it. (shrink)
