In this work, we focus on the problem of selecting low-level heuristics in a hyperheuristic approach with offline learning, for the solution of instances of different problem domains. The objective is to improve the performance of the offline hyperheuristic approach, identifying equivalence classes in a set of instances of different problems and selecting the best performing heuristics in each of them. A methodology is proposed as the first step of a set of instances of all problems, and the generic characteristics (...) of each instance and the performance of the heuristics in each one of them are considered to define the vectors of characteristics and make a grouping of classes. Metalearning with statistical tests is used to select the heuristics for each class. Finally, we used the Naive Bayes to test the set instances with k-fold cross-validation, and we compared all results statistically with the best-known values. In this research, the methodology was tested by applying it to the problems of capacitated vehicle routing and graph coloring. The experimental results show that the proposed methodology can improve the performance of the offline hyperheuristic approach, correctly identifying the classes of instances and applying the appropriate heuristics in each case. This is based on the statistical comparison of the results obtained with those of the state of the art of each instance. (shrink)

The present study aims to verify the psychometric properties of the Spanish versions of the Social Roles Questionnaire (SRQ; Baber & Tucker, 2006), Modern Sexism scale (MS) and Old-fashioned Sexism scale (OFS; Swim et al. Swim & Cohen, 1997). Enough support was found to maintain the original factor structure of all instruments in their Spanish version. Differences between men and women in the scores are commented on, mainly because certain sexist attitudes have been overcome with greater success in the current (...) Spanish society, while other issues, such as distribution of power in organizational hierarchies or distribution of tasks in the household, where traditional unequal positions are still maintained. In all cases, it was found that men showed greater support for sexist attitudes. The correlations between the three instruments were as expected in assessing sexist attitudes that tend to relate to each other. Eventually, we found no empirical evidence for the postulated link between sexist attitudes and traditional gender stereotypes. Our results call for the validity and effectiveness of the classic theories of gender psychology, such as gender schema theories (Well, 1981; Markus et al., 1982) and the notion of a gender belief system (Deaux & Kite, 1987; 2001).

Este trabajo se propone estudiar las características de los paralogismos de composición y división (Retórica II 24.II, 1401a), de la consecuencia (Retórica II 24.VI, 1401b20-30) y de la causa aparente (Retórica II 24.VII, 1401b30-34), de modo de analizar si Eurípides los utiliza en el agón de Andrómaca de los versos 577 a 746 This paper intends to study the characteristics of paralogisms due to composition and division (Rhetoric II 24.II, 1401a), due to consequent (Rhetoric II 24.VI, 1401b20-30), and due to (...) false cause (Rhetoric II 24.VII, 1401b30-34), in order to analyze if Euripides uses them in the agon in Andromache (577-746).

Martin Heidegger's Nietzsche's Second Untimely Meditation presents crucial elements for understanding Heidegger's thinking from 1936 to 1940. Heidegger offers a radically different reading of a text that he had read decades earlier, showing how his relationship with Nietzche's has changed, as well as how his understandings of the differences between animals and humans, temporality and history, and the Western philosophical tradition developed. With his new reading, Heidegger delineates three Nietzschean modes of history, which should be understood as grounded in (...) the structure of temporality or historicity and also offers a metaphysical determination of life and the essence of humankind. Ullrich Hasse and Mark Sinclair offer a clear and accessible translation despite the fragmentary and disjointed quality of the original lecture notes that comprise this text. (shrink)

Growing interest has been shown toward humanism in the 21st century after decades of critique and rejection. Posthumanism and transhumanism have redefined the topic primarily through developments in technology and by focusing on relations of interconnectedness between humans and the environment. A different concern with ‘being human’ can be found in the writings of Zygmunt Bauman and Ernst Bloch. The leitmotif of Bauman’s sociology and of Bloch’s utopian philosophy is their assertion that humans have the distinct capacity to transcend necessity (...) and inevitability. Their works share the concern for a good society that would ameliorate social fragmentation and disintegration. Following this, the article seeks to theorize the meaning of humanism in the contemporary era. Taking up Bauman’s notion of interregnum, the article will argue that the contemporary importance of humanism is social in the sense of redeeming the currently casualized human condition, i.e. diminished life-chances, inequality and alienation. Interregnum marks a historical epoch where the old order has decayed, but the new one is not yet present. In interregnum, or in what Bloch calls Mischzeit, humanism is about a human being-in-the-world which contains the possibility to do better. (shrink)

Među mnoštvom dimenzija kolektivnog identiteta, ovaj rad istražuje identitet kao retorički alat. Identitetska oznaka je upravo primjer pragmatične učinkovitosti. Kako bi se objasnila ta moć, izložit će se hipotetički model identitetskih kategorija. Njegovi konstitutivni moduli oblikuju četiri osnovne dimenzije: pozicija, deindividualizacija, isključenje i kognitivna zaštita. Tako ocrtan narativni identitet postaje ekvivalentan neformalnoj ideologiji . Kao konstitutivna retorika , narativna konstrukcija identiteta pretvara autoreferencijalnu tautologiju u strategije diskriminacije, pročišćenja i istrebljenja nositelja drugosti. Masovna uništenja u prošlom stoljeću – totalitarizam, kolonijalizam, etno-nacionalizam (...) – proizvodi su identitetske paradigme. (shrink)

In “Principled Compromise and the Abortion Controversy” Simon C. May argues that we do not have a principled moral reason to compromise. While I seek to understand how more precisely we are to understand this suggestion, I also object to it: I argue that we have a principled moral reason to accept democratic decisions that we disagree with, and that this can only be so if disagreement can change what the all things considered right political position is. But if this (...) is so, then also a principled moral reason to compromise is possible. I suggest that there is a class of procedures, including compromise, voting, expert delegation, and coin flip, such that when we disagree about what justice requires, we have a principled moral reason to engage in one of these procedures.

El objetivo de este trabajo es criticar un artículo de Michael B. McNulty publicado en 2015, a saber, “Rehabilitating the Regulative Use of Reason: Kant on Empirical and Chemical Laws”. En este artículo, McNulty examina la concepción kantiana de la necesidad de las leyes empíricas pertenecientes a lo que, en los Primeros principios metafísicos de la ciencia de la naturaleza, se denomina ciencia en un sentido “impropio”. McNulty considera la única ciencia en sentido impropio mencionada por Kant, a saber, la (...) química. En su artículo, McNulty presenta una interpretación original e interesante de esa concepción. Según esta interpretación, ciertas ideas de la razón, que el autor llama “elementos”, son el fundamento de la necesidad de las leyes químicas. Haremos tres críticas a esta interpretación. 1) La tesis de McNulty según la cual desde la perspectiva de la razón las leyes químicas son estrictamente necesarias es cognitivamente irrelevante para nosotros. 2) McNulty no menciona textos de Kant que muestren claramente que su interpretación del fundamento de la necesidad de las leyes químicas es correcta. 3) Nuestra interpretación de la necesidad regulativa de las leyes químicas es más cercana a la concepción kantiana de esas leyes que la lectura de McNulty.

El objetivo de este trabajo es mostrar las diferencias y relaciones entre las concepciones kantianas de dos disciplinas. La primera es la psicología empírica contenida en la Metafísica de Baumgarten, que Kant empleaba para dar sus lecciones de antropología. Consideraremos principalmente la interpretación kantiana de esta psicología. La segunda es la antropología pragmática. Con respecto a esta última disciplina, tendremos en cuenta las lecciones de antropología de Kant y la publicada Antropología en sentido pragmático. Mostraremos que, aunque las concepciones kantianas (...) de la psicología empírica y la antropología pragmática son esencialmente diferentes, hay relaciones entre las mismas. Nuestra conclusión es que la psicología empírica permanece como un cierto enfoque metodológico dentro de la antropología pragmática. Tal enfoque consiste en la consideración de los fenómenos internos, y es uno, entre otros, de los recursos metodológicos empleados por la antropología pragmática. (shrink)

The public is largely innumerate, making systematic mistakes in estimating some politically relevant facts, such as the share of foreign-born citizens. In two-step or multistep flow models, such mistakes could be corrected if better-informed citizens were able to convince their peers, in particular by using good arguments citing reliable sources. In six experiments, we find two issues that dampen the potential power of this two-step flow process. First, even though participants were more convinced by good than by poor arguments, many (...) did not change their minds, even when confronted with good arguments. Second, participants are not inclined to spontaneously generate arguments that cite reliable sources, even when they have just been influenced by such arguments. Both issues should put a significant brake in the spread of political numeracy through the two-step flow process, in particular in non-dialogic contexts. (shrink)

The scene inIliad11 where Nestor's slave Hekamede prepares a restorative κυκεών for his guests in his great cup, which only he can lift when it is full, has often been cited in connection with the skyphos from Ischia, dated toc.735–720 BC, with its verse inscription that alludes to Nestor's εὔποτον ποτήριον. Now that scholarly opinion is increasingly swinging towards a seventh-century dating for theIliad, it seems more prudent than ever to see the Ischia inscription as a reflex not of ourIliadbut (...) of a similar Nestorian drinking episode in earlier epic tradition. His cup, as described, has features of a Bronze Age vessel; and the motif of the mighty goblet is paralleled in the Ugaritic Baal epic, current not later than the fourteenth century.Here I want to consider another element in the scene, namely the grated cheese which Hekamede adds to her posset. I hope to show, by a combination of metrics and archaeology, that this too, even though it cannot be traced back to the Bronze Age, belongs to a traditional account that is many generations older than ourIliad.

Zusammenfassung Im illegalen Nierenhandel werden Verkaufer oft uber den Tisch gezogen, sie werden genotigt, es wird ihnen angemessene medizinische Betreuung vorenthalten und sie werden uber die Gefahren und die Illegalitat der Nierenentnahme in die Irre gefuhrt. Die Empfanger bezahlen oft fur qualitativ schlechte Operationen sowie ungesunde oder unpassende Nieren. Einige Autoren argumentieren, es sei die Illegalitat, die dieses Leid und dieses Unrecht verursachen, nicht der Handel an sich. Sie argumentieren, die Legalisierung von Nierenverkaufen wurde das Leid verringern. Dieses Leidensverringerungsargument ist (...) es, das in diesem Aufsatz entwickelt und untersucht wird. Es werden zunachst die ethischen und empirischen Bestandteile einer utilitaristischen Version von Leidensverringerung dargelegt. Und es wird erklart, wie eine Legalisierung das Leiden auf Schwarzmarkten vermutlich verringern wurde, aber auch, warum wir nicht wissen, wie die Legalisierung das Angebot an Organen oder die Anzahl leidvoller Transaktionen auf ‘weisen Markten’ beeinflussen wurde. Kurz gesagt, wir konnen nicht sicher sein, dass seine Legalisierung das Leiden insgesamt verringern wurde. Dennoch versucht dieser Aufsatz zu zeigen, dass die Argumentation zugunsten von einer Legalisierung gestarkt werden kann, wenn man dem utilitaristischen Hauptanliegen des aggregierten Wohlergehens etwas hinzufugt. Den besonderen Anliegen der am schlechtesten Gestellten und dem Unrecht des Verkaufsakts kann man durch Legalisierung besser gerecht werden als durch Kriminalisierung. Das Leidensverringerungsargument entscheidet diese Debatte uber die Legalisierung des Organhandels zwar nicht, aber es ist entscheidender als Kritiker bislang zugestehen wollten. (shrink)

Reorientation: Leo Strauss in the 1930s seeks to explain the 'change in orientation' that Strauss underwent during a decade of personal and political upheaval. Though he began to garner attention in the 1950s, it was in the 1930s that Strauss made a series of fundamental breakthroughs which enabled him to recover, for the first time since the Middle Ages, the genuine meaning of political philosophy. Despite this being a period of marked output and activity for Strauss, his research in this (...) era remains overlooked. This volume is the first to assemble in one place an examination of Strauss' various publications throughout the decade, providing a comprehensive analysis of his work during the period. It includes, for the first time in English, five newly translated writings of Strauss from 1929-37, brought to life with insight from leading scholars in the field. (shrink)

Recognize the “philo- sophia ” as such, this side of Postmodernism, means, starting from the surprising studies of Heribert Boeder, see it as a thought epochally built on a Wisdom, that is, on a initial Knowledge about the Destiny of Man. For the philo-sophical thought of the so-called “German Idealism”, that Wisdom is neither that of the Muses, as in the First epoch, neither the “Christian sapientia”, as in the Middle epoch, but the “Civil Consciousness” about Duty and Freedom.

It is not uncommon to hear that poor school performance, welfare dependancy, youth unemployment, and criminal activity result more from shortcomings in the personal makeup of individuals than from societal forces beyond their control. Are American values declining as so many suggest? And are those values at the root of many social problems today?Shaped by experience and public policies, people's values and social norms do change. What role can or should a democratic government play in shaping values? And how do (...) these values conditon the efficacy of public policy?In this book, six distinguished social scientists identify trends in America's values and their consequences, and consider public policy tools with which some of those values might be changed.Daniel Yankelovich begins with a discussion of how American values have shifted in the last half-century, and argues that affluence is the driving force behind these changes in values. James Q. Wilson argues that destructive habits which can lead to social pathologies, like crime and drug use, are set early in life; he examines how public policy might intervene when children are young to promote better values. David Popenoe maintains that America has veered too far towards industrialist values, and explores the resulting decline of families and many attendant social ills. Nathan Glazer describes the history and present status of the dispute over multicultural education. Jane Mansbridge examines the process of building cooperation, consensus, and public spirit. And George Akerlof and Janet L. Yellen discuss the problem of gang criminality.Inthe past, social scientists have often sidestepped questions about values as undefinable, unquantifiable, and somehow unscientific. The essays in this volume address these questions at last.Henry J. Aaron, director of the Economic Studies program at Brookings, is the authorof numerous books, including most recently Serious and Unstable Condition: Financing America's Health Care (1991), and coeditor of Setting Domestic Priorities (1992).

L’auteur met en évidence la façon dont Thémistius, dans sa paraphrase, réorganise les parties du texte des lignes 71a17-b8 des Seconds Analytiques. Par une analyse détaillée du propos d’Aristote dans ces lignes, il montre que la réorganisation proposée par Thémistius est fidèle à l’esprit du texte aristotélicien, et s’appuie vraisemblablement sur des indices externes dont disposait le paraphraste.
