This article investigates the impacts of proper modeling of the wake effects and wind speed delays, between different wind turbines' rows, on the dynamic performance accuracy of the wind farms models. Three different modeling scenarios were compared to highlight the impacts of wake effects and wind speed time-delay models. In the first scenario, wind wake effect and time delay are ignored. Consequently, all wind turbines are assumed subjected to the same wind speed profile. The second scenario considers the wind wake (...) effect, and it was modeled by reducing the incident wind speed values by 0.5 m/s from one row to the next row facing the wind. The last scenario, the proposed model, used the wind wake effect model developed for wind turbines micrositting applications and considered the effect of the delay time between the wind speed profiles incident on the different wind turbines' rows.

resumenEl ensayo trata de resaltar diversos aspectos promisorios y progresistas contenidos en el llamado orden premoderno y en la época anterior a la Primera Guerra mundial. Entre estos factores se hallaban la configuración de una estructura familiar sólida, la existencia de individualidades fuertes con concepciones firmes sobre la ética cotidiana y una cultura todavía alejada del relativismo axiológico a ultranza. Esta era del liberalismo clásico se diferenciaba del actual “capitalismo volátil”, caracterizado por su narcisismo autorreferencial y sus tendencias tecnocráticas. A (...) lo positivo del mundo de ayer contribuyó una aristocracia con algunos rasgos premodernos, que reconocía los límites que nos imponen el entorno natural y las carencias humanas.Palabras clave:alta cultura, aristocracia, límites, modernidad, tradicionalidadThe essay tries to detect some promising and progressive aspects which were embodied in the so-called premodern order and in the time previous to the First World War. Among those factors we can mention a solid familiar structure, the existence of strong individualities with firm conceptions about the daily sphere of ethics and a high culture, which was still very distant from the actual and extreme relativism of values. That time of classical liberalism was very different in comparison with the actual “volatile capitalism”, which is characterized by selfrefering narcissism and technocratic tendencies. A contribution to the positive aspects of the world of yesterday was done by an aristocracy, which acknowledged the limits fixed upon us by the natural environment and the human failures.Key words:high culture, aristocracy, limits, modernity, traditionality.

ResumenBasado en elementos de la filosofía clásica, el common sense británico y la Escuela de Frankfurt, el autor postula un sentido común guiado críticamente, que serviría para evaluar las tendencias históricas y los modelos de modernización en el Tercer Mundo. Evitando extremos, este teorema rechazaría tanto las pretensiones de verdad de muchos enfoques racionalistas como el relativismo epistemológico y ético. La existencia de leyes y etapas obligatorias de la historia es uno de esos extremos; otro es la opción teórica que (...) afirma que los modelos culturales son incomparables e inconmensurables entre sí. La existencia de un solo paradigma normativo-positivo de desarrollo es insostenible, pero igualmente la posición que decreta la diversidad e incomparabilidad totales de los regímenes civilizatorios. Es conveniente adoptar una línea intermedia entre universalismo y particularismo y alcanzar una síntesis fructífera de ambos.Palabras claveEscuela de Frankfurt, Habermas, Kant, particularismo, sentido común, universalismoAbstractBased on elements of classical philosophy, the British common sense and the Frankfurt School, the author proposes a critically guided common sense, which could be used to evaluate historical tendencies and specially the modernization efforts in the Third World. Avoiding extremes, this theorem rejects the pretensions of truth of rationalist theories and also the epistemic and ethic relativism. The existence of obligatory laws and periods of historical development is one of these extremes; the other one is the position which states that cultural models are incomparable and immeasurable. It is reasonable, for instance, to take a middle way between universalism and particularism and also to reach a fruitful synthesis between both currents.KeywordsCommon sense, Frankfurt School, Habermas, Kant, particularism, universalism.

RESUMENUn intento por comprender la realidad sociopolítica podría consistir en situarse entre posiciones que marcan polos opuestos en el espectro de las ideas. Desde la filosofía griega se conocen las bondades y desventajas de colocarse en puntos intermedios que se hallan entre actitudes extremas en lo concerniente a asuntos morales y sociales. Una de las respuestas plausibles es una forma de eclecticismo, que tendría la función de una síntesis fructífera. Este teorema del sentido común guiado críticamente se asienta en concepciones (...) filosóficas clásicas, incluyendo la Escuela de Frankfurt. El ensayo pone como ejemplo principal el tratamiento de las utopías políticas.PLABARAS CLAVEARISTÓTELES, HABERMAS, HEGEL, SENTIDO COMÚN, TEORÍA CRÍTICA, UTOPÍAABSTRACTAn effort to understand the social-political reality could consist in taking a position between opposite poles in the spectrum of ideas. The advantages and disadvantages of placing oneself midway between extreme attitudes concerning moral and social problems have been aknowledged since Greek philosophy. A plausible answer is a form of eclecticism, which could have the function of a fertile synthesis. This theorem of a critically guided common sense is based on classic philosophic conceptions, including the Frankfurt School. This essay sets the analysis of political utopias as a main example.KEY WORDSARISTOTLE, COMMON SENSE, CRITICAL THEORY, UTOPY. (shrink)

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

The importance of the Low Countries as a centre for the study of foreign languages is well-known. The mutual relationship between the Dutch grammatical tradition and the Western European context has, however, been largely neglected. In this collection of papers on the history of linguistics in the Low Countries the editors have made an effort to present the Dutch tradition in connection with that of the neighbouring countries. Three articles by Claes, Dibbets and Klifman deal with the earliest stages of (...) the development of a grammar for the Dutch vernacular. Several important European figures worked in the Low Countries; their contribution to linguistics is discussed in articles on Vossius (Rademaker), Spinoza (Klijnsmit), and one of the most original phoneticians of European linguistics, Montanus (Hulsker). Vivian Salmon's article is a survey on the relations between English and Dutch linguistics in the field of foreign language teaching. In the 19th century Dutch linguistics had a special relationship with German general and historical linguistics; four articles deal with this period (Jongeneelen, van Driel, le Loux-Schuringa, Noordegraaf). Finally, there are three articles by Kaldewij, Hagen and van Els/Knops on the development of three branches of linguistics in the 20th century: structuralism, dialectology and applied linguistics. This volume should be of interest for all specialists in the history of linguistics in Europe, who are interested in the interdependence of the various traditions. (shrink)

"Not only one of the best but also the most comprehensive treatment of Stoicism written in this century." --Times Literary Supplement.

In lieu of an abstract, here is a brief excerpt of the content:Kinship:The Relationship Between Johnstone's Ideas about Philosophical Argument and the Pragma-Dialectical Theory of ArgumentationFrans H. van Eemeren and Peter Houtlosser1. Johnstone on the Nature of Philosophical ArgumentAs he himself declared in Validity and Rhetoric in Philosophical Argument (1978, 1), the late philosopher Henry W. Johnstone Jr. devoted a long period of his professional life to clarifying the nature of philosophical argument. His well-known view was that philosophical arguments are (...) sui generis, i.e., not to be judged by the standards of argumentation in science or everyday discourse. Philosophical arguments are not ad rem, but are based on premises that are expressed or implied commitments of a party in dialogue. This is why philosophical argumentation is, according to Johnstone, always ad hominem. In philosophical argumentation, every ad rem argument begs the question.Usually, ad hominem argumentation is dismissed as invalid. Johnstone, however, maintains that making use of argumentum ad hominem is the only way to establish a philosophical conclusion. In an argumentum ad hominem, inferences are drawn from propositions stated or implied by the other party and critical questions are raised about the conclusions that were drawn, so that it can be used to refute a philosophical position by showing that this position is inconsistent. As Walton (2001) rightly observes, this type of ad hominem argumentation boils down to arguing from commitments of the other party, i.e., ex concessis.The use of ad hominem argumentation as the criticism of a position in terms of its own presuppositions is, in Johnstone's view, the only valid argument in philosophy, if any philosophical argument is indeed valid. All philosophical polemic is in this perspective in fact addressed ad hominem. This applies not only to philosophical argumentation that concerns self-referential refutation but also to other ad hominem types of philosophical argumentation, including the tu quoque argument (1978, 11–12).According to Johnstone, there is no objective criterion for determining the validity of ad hominem argumentation. Validity must, says Johnstone in the [End Page 51] epilogue of his collected essays on philosophical argument, be viewed as "a regulative ideal" (135). Much earlier, Johnstone had already come to the conclusion that "the valid argument is the one that maintains philosophical discussion" (38). It is this self-perpetuating feature that is the distinctive rationality of philosophy. By forcing the interlocutor to elaborate his philosophical position rather than just repeat it, the gap between the interlocutors is bridged.In order to distinguish between constructive persuasive argumentation and mere repetition or other forms of paralyzing the discourse, the line must be drawn between responsible and irresponsible persuasion. This is a problem for Johnstone. Where the Ancients solved the problem by insisting that the persuader be virtuous, Johnstone proposed to base the distinction between responsible and irresponsible persuasion on the attitude of the philosopher and his interest in maintaining the philosophical enterprise. The philosopher is a critic who criticizes con amore. His intention to do so, however, is revealed "only in the way he goes about his work" (84).A more down to earth criterion for responsible persuasion that Johnstone proposed is that the discourse should not tend to degenerate. Logic, as the discipline concerned with reason, serves to prevent the discussion from degenerating, but it can do so only if the parties concerned have jointly committed themselves to certain logical principles. If in philosophical argument a defendant is under no obligation to acknowledge an inconsistency when the other party points out an inconsistency in his position, then the other party's criticism cannot count as valid. According to Johnstone, however, it will depend on the parties' presuppositions whether or not they consider two statements as being inconsistent. In other words, what is inconsistent for the one party may not be inconsistent for the other party.Few obligations are imposed on everyone; most obligations arise from commitments made by specific individuals or groups of individuals. As Johnstone says, "Even the cogent philosophical argument is not, of course, absolutely cogent; it is cogent only relatively to interlocutors who maintain the premises on which it depends" (27). Once we abandon the search for objective conditions under which philosophical arguments can be valid, according... (shrink)
