This paper is about a support information management system for a wind power producer having an energy storage system and participating in a day-ahead electricity market. Energy storage can play not only a leading role in mitigation of the effect of uncertainty faced by a WP producer, but also allow for conversion of wind energy into electric energy to be stored and then released at favourable hours. This storage provides capability for arbitrage, allowing an increase on profit of a WP (...) producer, but must be supported by a convenient problem formulation. The formulation proposed for the support information management system is based on an approach of stochasticity written as a mixed integer linear programming problem. WP and market prices are considered as stochastic processes represented by a set of scenarios. The charging/discharging of the ESS are considered dependent on scenarios of market prices and on scenarios of WP. The effectiveness of the proposed formulation is tested by comparison of case studies using data from the Iberian Electricity Market. The comparison is in favour of the proposed consideration of stochasticity. (shrink)

Noting that one may hear without listening, the article probes the phenomenological and epistemic distinction between hearing and listening. To listen is to be attuned to voices muffled by silence or camouflaged by a defensive rhetoric resonant with a voice inflected by festering wounds, existential and political. In exploring how one is to listen to these voices of silence, I draw upon Martin Buber’s concept of dialogical “inclusion” of others’ stories, to listen without interpretation to allow the voice behind his (...) – or her or their – story, be it merely etched viscerally in the language of silence, to dwell aside one’s own story in a dialogue unencumbered by perceptions of the Other forged by cultural, social, political constructs, and perhaps most insidiously one’s own defensive postures.

The aim of this paper is to clarify the truth-functional interpretation of the logical connective of the material implication. The importance of such clarification lies in the fact that it allows avoiding the supposed paradoxes introduced by C. I. Lewis (1918). I argue that an adequate understanding of the history and purposes of logic is enough to dissolve them away. The defense is based on an exposition of propositional compositionalism. To compare, I also present Stalnaker’s (1968) alternative that seeks to (...) explain the implicit concept of conditionality of conditionals assertions. In order to reinforce my aim I expound the twelve different meanings of ‘implication’ stated by Corcoran (1993) in order to hold that a proper understanding of these meanings allows us to avoid ambiguities and confusions. Finally, I expect to show that despite the possible alternatives, compositionalism is still the best explanation for the truth-functionality account of logical connectives. (shrink)

Our work is aimed at studying the optimization of a complex motor behaviour from a global perspective. First, free climbing as a sport will be briefly introduced while emphasizing in particular its psychomotor aspect called route finding. The basic question raised here is how does the optimization of a sensorimotoricity-environment system take place. The material under study is the free climber's trajectory, viewed as the signature of climbing behaviour (i.e., the spatial dimension). The concepts of learning, optimization, constraint, and degrees (...) of freedom of a system will be discussed using the synergistic approach to the study of movement (Bernstein, 1967; Kelso, 1977). Measures of a trajectory's length and convex hull can be used to define an index whose equation resembles that of an entropy. This index is a measure of the trajectory's overall complexity. Some important concepts related to the thermodynamics of curves will also be discussed. The optimization process will be studied by examining the changes in entropy over time for a set of trajectories generated during the learning of a route (ten successive repetitions of the same climb). It will be shown that the entropy of the trajectories decreases as learning progresses, that each level of expertise has its own characteristic entropy curve, and that for the subjects tested, the mean entropy of skilled climbers is lower than that of average climbers. Basing our analysis on the concepts of degrees of freedom and constraint equations, an attempt is made to relate trajectory entropy to system entropy. Based on the postulate that trajectory entropy is equal to the difference in entropy between the unconstrained and constrained system, a model of motor optimization is proposed. This model is illustrated by an entropy graph reflecting a dynamic release process. In the light of our results, two opposing views will be examined: movement construction vs. movement emergence.

_The first major biography in English in over thirty years of the seminal modern Jewish thinker Martin Buber_ An authority on the twentieth‑century philosopher Martin Buber, Paul Mendes-Flohr offers the first major biography in English in thirty years of this seminal modern Jewish thinker. The book is organized around several key moments, such as his sudden abandonment by his mother when he was a child of three, a foundational trauma that, Mendes-Flohr shows, left an enduring mark on Buber’s (...) inner life, attuning him to the fragility of human relations and the need to nurture them with what he would call a “dialogical attentiveness.” Buber’s philosophical and theological writings, most famously _I and Thou,_ made significant contributions to religious and Jewish thought, philosophical anthropology, biblical studies, political theory, and Zionism. In this accessible new biography, Mendes-Flohr situates Buber’s life and legacy in the intellectual and cultural life of German Jewry as well as in the broader European intellectual life of the first half of the twentieth century.

The aim of this study is to show that the reopening of the “quarrel between the ancients and the moderns” proposed by Strauss is an invitation to rethink the format of social science of his time. In his interpretation, the triumph of positivism and historicism in the contemporary era directly influenced the consolidation of a kind of social science that was too technical and scientistic, far from its main object of research, the human life in society. As a result, it (...) was established a nihilistic social science, attached to methods and a theorizing vocabulary, incapable of dealing with the complexity of the human world. I intend to show, based on the criticism elaborated by Professor Strauss, which alternatives are presented to rescue social science through the revival of specific elements of classical political science.

O filósofo dinamarquês Søren A. Kierkegaard é frequentemente lido, dentro da própria tradição intérprete, como um crítico das Ciências Naturais (Naturvidenskaben). 1 Neste artigo, pretendo argumentar, ao contrário, que Kierkegaard: (i) foi crítico de uma determinada prática científica do seu tempo epistemicamente frágil e dos cientistas naturais que a adotavam construindo uma proposta judiciosa do papel da Ciência na interpretação do mundo; (ii) interessou-se pelas Ciências Naturais, inclusive pelos trabalhos do seu primo, o paleontólogo Peter Wilhelm Lund, e as pesquisas (...) de Hans Christian Ørsted, um expressivo cientista dinamarquês contemporâneo; (iii) ao criticar os pressupostos metodológicos de Carl Gustav Carus, o primeiro psicólogo a fazer referência à existência do inconsciente, Kierkegaard toma partido no vitalismus-materialismusstreit; (v) Por fim, e talvez mais importante, Kierkegaard propôs limites éticos e epistêmicos à Ciência e inspirou os pressupostos da filosofia da ciência de filósofos contemporâneos como Paul Feyerabend.

_“Emotion as an element of contemporary Criticism in the intellectual Environment of the Weimar Republic – A contextual Reading of the Presentation of the Affective in Martin Heidegger and Carl Schmitt”_ This article examines a specific use of emotional concepts as well as a particular understanding of the affective in general in the work of Heidegger and Schmitt during the years 1919-1933. The general character of this idea of the affective is that it is developed as an element of a (...) critical engagement with discourses regarding institutional change. Thus, I will be reading the two thinkers in the light of institutional disputes present in the Weimar Republic. Heidegger is read in relation to the question of university reform, with which he was deeply involved in the 1920´s. Schmitt will be analyzed through the political situation of the newly established liberal democracy. In both cases, I will argue that a conception of the affective is developed that serves to attack a perceived relativism. This is seen in the fact that, for both thinkers, certain affective categories are linked to stable existential categories: being for Heidegger and the dichotomy between friend and foe for Schmitt.

I Books and Order In an autobiographical essay, Walter Benjamin tells of moving to a new apartment and unpacking his library from the crates that had transported them to their new abode. While reassembling his library, he reflects upon the random, often fortuitous manner in which the books were acquired. But once they are placed on the shelves of his library they gain an order, at least in his imagination. As constellated in his library, the tomes form a distinctive bibliophilic (...) and intellectual landscape, marking the byways of his spiritual biography. To be sure, the order the books attained on the shelves of Benjamin's library may not have been readily discerned by others who may even have had difficulty in grasping the inner logic of his collection.

ExcerptA series of recent works have explored Hans Blumenberg's metaphorology in its relation to anthropology and the hermeneutics of the lifeworld.1 In what follows, I would like to foreground another aspect of his work by describing the metaphorology and the earlier works on the history of philosophy as works of discourse analysis. From such a perspective, linguistic forms appear less as the expression of anthropological and lifeworld circumstances than as the continuation and transformation of intra-discursive, historical-systematic decisions. I suggest that (...) the functional-anthropological and the discourse-analytical readings of Blumenberg supplement one another insofar as they each give weight to different…. (shrink)

Recently, calls have grown louder for more stakeholder democracy that is, letting stakeholders participate in the process of organizing, decision‐making, and governance in corporations, especially in the area of Corporate Social Responsibility (CSR) activities. Despite the relevance of the subject, the impact of customer involvement in CSR on their company‐related attitudes and behaviors still represents a major research void. The paper at hand develops a conceptual framework of consumer involvement in CSR based on the existing literature, theories of stakeholder democracy, (...) and organizational boundaries as well as drawing from the qualitative focus group interviews (N = 24). The framework is tested on a large scale, two‐time point field‐experimental study (N = 3,397). More specifically, consumer reactions to three degrees of customer involvement (i.e., information, feedback, and dialogue) are tested in two different CSR domains (i.e., company‐internal business process vs. company‐external philanthropic CSR). Results indicate that the customer involvement in CSR has a more beneficial effect in terms of strengthening customer outcomes in CSR domains that directly affect external stakeholders of the company (i.e., philanthropic CSR) than in domains that mainly concern company‐internal stakeholders (i.e., business process CSR).

O artigo traz resultados de uma investigação de mestrado que teve por objetivo pesquisar as concepções de um grupo de professores a respeito das funções que os mesmos exercem frente à sociedade contemporânea. Partiu-se da premissa de que suas concepções guardam relação com suas práticas educativas e pedagógicas. Trata-se de uma pesquisa desenvolvida na perspectiva qualitativa, com cinquenta e um professores que atuam em seis escolas estaduais da cidade de Ponta Grossa-PR. Elegeu-se como aporte teórico autores que tratam da formação (...) de professores e da profissão docente, como Freire, Imbernón, Ens e Behrens, Tozetto, Sacristán e Tedesco. Os dados foram coletados por meio de questionários, categorizados e analisados seguindo os pressupostos na Análise de Conteúdo. Três categorias foram configuradas a partir de significantes presentes nas respostas dos professores participantes: Categoria I – Professor como um sujeito transformador: educação em uma forma ampla, Categoria II – Professor como profissional do conhecimento, e Categoria III – Professor enquanto sujeito que desempenha vários papéis sociais. Essas categorias nos possibilitaram inferir que as concepções dos professores em relação ao seu papel na sociedade contemporânea vão além da função social da escola, pois centram-se primeiramente na figura de um profissional transformador do mundo; seguida da noção de profissional do conhecimento e, por fim, da ideia de um profissional que desempenha vários papéis sociais. A pesquisa também apontou uma necessária redefinição da profissão docente para que os professores assumam novas competências profissionais na contemporaneidade. Palavras-chave: Profissão docente. Função dos professores. Sociedade contemporânea. Concepções. (shrink)
