Este artículo sobre la investigación doctoral en curso: Pedagogía de la Madre Tierra y Euritmia: diálogo intercultural de saberes pedagógicos, explora la pregunta por otras formas de investigar en pedagogía, que permitan ampliar sus saberes en la formación docente. Los saberes `otros´ nacidos del diálogo entre lo ancestral y lo corporal, serán nombrados matrices pedagógicas, apelando a la cualidad femenina de la palabra matriz. Éstas serán comprendidas, incorporadas y reflexionadas desde el método denominado “Pregúntale al Cuerpo”, el cual emerge del (...) trabajo de campo. Finalmente se esbozan algunas líneas de sentido que van apareciendo en el trabajo en curso. (shrink)

After World War II, infant mortality rates started dropping steeply. We show how this was accomplished in socialist countries in East-Central Europe. Focusing on the two postwar decades, we explore comparatively how medical experts in Poland, Hungary, Czechoslovakia, and East Germany saved fragile newborns. Based on an analysis of medical journals, we argue that the Soviet Union and its medical practices had only a marginal influence; the four countries followed the recommendations of the World Health Organization instead, despite not being (...) members. Importantly, we analyze the expert clashes over definitions of livebirth, which impact infant mortality statistics. We analyze the divergent practices and negotiations between countries: since the infant mortality rate came to represent the level of socioeconomic advancement, its political significance was paramount. Analyzing the struggle to reduce infant mortality thus helps us understand how socialist countries positioned themselves within the transnational framework while being members of the “socialist bloc.”.

This study shows how institutional work contributes to institutional resilience in extreme operating environments. The authors draw from a longitudinal analysis of the operations of Desjardins International Development, a French Canadian nongovernmental organization that, both before and after the major earthquake of 2010, supported the implementation of cooperative banking in Haiti. Building on a unique access to DID’s internal documents as well as on 49 interviews with DID employees, the authors highlight the ways in which political, technical, and cultural forms (...) of institutional work triggered the emergence of social capital, which in turn supported the rise of new forms of institutional work that enabled institutional resilience. The results show how organizational activities focused on shaping institutions may have unintended effects that enable institutional resilience in EOEs, and demonstrate how the accumulation of institutional work by an organization contributes to the enhancement of its social capital.

En este segundo documento nos ocupamos del aborto realizado por motivos terapéuticos o, dicho más brevemente, del aborto terapéutico. En la Argentina, el aborto plantea serios desafíos para la salud pública, ya que, pese a estar prohibido, se practica de forma clandestina y, muchas veces, insegura, poniendo en riesgo la vida y la salud de las mujeres. Por esta razón, creemos que la sociedad y el Estado deben debatir este problema y encontrar soluciones que resguarden los derechos de las mujeres. (...) El artículo 86, inciso 1, del Código Penal argentino expresamente despenaliza el aborto cuando corre peligro la vida o la salud de la mujer. En estos casos, se habla de aborto terapéutico. Esta disposición legal no suele aplicarse ni por los médicos ni por los profesionales que trabajan en la justicia, ya sea por desconocimiento o por razones ideológicas. Más aún, en muchos casos, las interpretaciones del Código Penal se apartan de su letra y restringen arbitrariamente su aplicación. Por estas razones, nos parece importante analizar este problema y proveer información sobre los aspectos legales y éticos involucrados en el aborto terapéutico en la Argentina. Este documento comienza con el relato de un caso hipotético, elaborado a partir de experiencias reales, con el objetivo de acercar al público a una situación concreta. Intercaladas en el cuerpo del relato, se desarrollan algunas reflexiones acerca de las implicaciones médicas, éticas y legales del caso. A continuación, se presenta un apartado referido al marco legal en el que se deben encuadrar los casos de aborto no punible. El documento sigue con una serie de breves recomendaciones destinadas tanto a los profesionales que trabajan en el sistema judicial como a los profesionales de la salud. Por último, se incluye un apéndice que contiene los principios que rigen la interpretación en materia penal y el glosario médico y legal, donde se pueden buscar las palabras resaltadas a lo largo del documento.

The study explores communication strategies of ethno-nationalist terrorists with respect to their framing and identity building. Strategies of eight ethno-nationalist terrorist groups were analyzed using 70 articles published on the groups’ websites. Three cluster-analytic procedures and a correlational analysis were applied to strategies of problem definition, cause and responsibility attribution, treatment recommendations, and identity building. The analysis revealed various dimensions on which terrorists frame their content. No group-specific strategies of framing and identity building have been found yet, suggesting that the (...) strategies were universal across terrorist groups, and they were applied on a case-by-case basis. Knowledge about these strategies should advance counter-terrorism efforts, and assist in development of alternative identities among ethnic groups at risk of conflict. (shrink)

En el trabajo nos ocupamos de desarrollar el problema del enlace entre la filosofía teórica y la filosofía práctica o del tránsito entre naturaleza y libertad tal y como Kant lo aborda en la Introducción definitiva a la Crítica de la facultad de juzgar. Específicamente proponemos la hipótesis según la cual Kant describe el modo como dicho enlace se realiza, a través de la facultad de juzgar, a partir de dos modelos diferentes. Según el primer modelo, el tránsito se (...) efectúa a partir de la idea de un fundamento de unidad de lo suprasensible que subyace a la naturaleza y lo suprasensible por libertad. De acuerdo al segundo modelo, el tránsito es posible porque lo suprasensible por libertad es puesto como causa o fundamento de la ley natura. Nos enfrentamos, así, a dos modos de pensar diferentes el tránsito en cuestión y, por lo tanto, dos modos alternativos de pensar la realización de la libertad en la naturaleza. In the paper I develop the question of linking theory and practice or, in other words, the problem of the transition between nature and freedom in Kant's Introduction to his Critique of the Power of Judgment. I propose specifically the hypotheses according to which Kant describes indeed two different models through which the linking occurs. According to the first one the transition accomplishes thanks to the idea of a ground of the unite of the supersensible that would underlie nature and the supersensible presupposed by freedom. According to the second one, the transition is possible because the supersensible by freedom is put it as cause or ground of the law of nature. Thus we face to two different ways of thinking the linking between theory and practice and, consequently, two alternative ways of thinking the realization of freedom in nature. (shrink)

El objetivo de este artículo es proporcionar algunas claves históricas y conceptuales para comprender la historia del socialismo británico libertarian y su relación con la concepción fiduciaria del poder político y del poder económico. Las expresiones de este socialismo no son homogéneas, convivieron con otras ideas rivales llegando en ocasiones a mezclarse con ellas; y fueron formuladas siempre como respuestas concretas ante los problemas que planteaba cada momento histórico. Desde el socialismo republicano de algunos seguidores de Robert Owen hasta los (...) desafíos que planteó la New Left, las teorías fiduciarias encontraron hueco para abrirse paso en los escritos de estos socialistas libertarian. The objective of this paper is to provide some historical and conceptual keys to understand the history of libertarian British socialism, and its relationship with the fiduciary conception of political power and economic power. The expressions of this libertarian socialism are not homogeneous, they coexisted with other rival conceptions, sometimes mixing with them. Those articulations were always formulated as concrete responses to the problems laid out by different historical moments. From the republican socialism of some Robert Owen’s followers to the challenges exposed by the New Left, fiduciary theory found room to break through in the writings of these libertarian socialists.

En el artículo se plantea que la libertad de expresión es vulnerada de manera distinta a los escenarios tradicionales en razón del uso del Big Data y otras tecnologías como el análisis predictivo de datos y la personalización de contenido. Esta vulneración resulta diferente de la habitual puesto que no existe imposibilidad o limitación a expresar lo que se quiere de manera espontánea, sino que, la libertad de expresión se ve coartada ex ante a través de la generación (...) de circunstancias en las que lo que se expresa viene dado previamente a través de información adecuada de manera personalizada según el perfil de quien opina. Para lograr presentar esta tesis, se efectúa un marco de referencia en el que este fenómeno se contextualiza. Al final se realiza una propuesta para disminuir o eliminar esta vulneración a la libertad de expresión. (shrink)

Karl Popper postula que no puede haber una teoría científica del desarrollo histórico que sirva de base para la predicción. Para mejorar la sociedad es necesario recurrir a la ingeniería social gradual, que busca introducir cambios tentativos, en sí mismos valiosos, al margen de que exista o no un plan general. Si no se obtiene el resultado esperado, habrá oportunidad de rectificar. El progreso gradual, la necesidad de un equilibrio de fuerzas bajo el poder del Estado, y la proporción entre (...) Estado y sociedad son vitales para la conservación de la libertad. La base teórico-social se ilustra con el ejemplo de un país imaginado, en el cual luego de un comienzo promisorio, que parecía dirigido a la construcción de una sociedad más justa, se abandonó el gradualismo, surgieron las ilusiones utópicas y terminó por apartarse de toda planificación. Palabras clave: Estado; falsacionismo; gradualismo; historicismo; ingeniería social; libertad; marxismo; planificación; sociedad; utopía. Popper and freedom. Once upon a time there was a country that went off courseKarl Popper argues that there can be no scientific theory of historical development on which historical prediction might be grounded. In order to improve society it is necessary to resort to gradual social engineering, which seeks to bring about tentative changes, valuable in themselves, regardless of whether or not there exists a general plan. If one does not reach the expected result, there will be room for rectification. Gradual progress, the need for a balance of the forces under the State’s power, and the balance between State and society are vital for the preservation of freedom. The social-theoretical basis is illustrated with the example of an imaginary country, which after a promising start -seemingly aimed at building a more just society-, simply gave up gradualism, utopian illusions emerged, and finally all planning was abandoned. Keywords: State; falsationism; gradualism; historicism; social engineering; freedom; marxism; planning; society; utopia. (shrink)

La realización del sí mismo representa un cometido que interpela a nuestra propia identidad humana. La heterogeneidad y riqueza de las voces que hablan sobre el cómo responder a ello demandan una deliberación atenta y mesurada. Para algunos, esta tarea supone un alto costo intersubjetivo que eventualmente nos vemos orillados a pagar. Para otros, es apremiante establecer un límite a tal importe para, precisamente, salvaguardar al sí mismo. En esta escena, la propuesta reflexiva de Albert Camus nos ofrece un sensato (...) balance que nos permite situar las coordenadas en las que la conducción de la particular existencia se traduce en una realización compartida.

El propósito es explicar cómo la crisis de la institución familiar lleva implícita una crisis en el sujeto humano, que desde la auto­nomía y la libertad se proponía como proyecto de vida conformar una familia. El modelo de análisis está centrado en esa configu­ración de las nuevas formas de familia, mediadas por el influjo de las tecnologías, especialmente, las fotografías digitales o las selfies como formas de expresión cotidiana donde ya no está presente la narración ni la historia, aunque (...) sí está la imagen. La metodología de investigación utilizada en este análisis es la hermenéutica feno­menológica a partir de manifestaciones relacionales mediadas por un generador de significado como es la selfie que se pone presente en este espacio conjunto de realidad y virtualidad. La tarea desde la educación es ser propositivos construyendo con los jóvenes nuevos sentidos de esperanza para que esas nuevas formas de familia sean espacios de amor. (shrink)

Siempre ha existido un contante problema entre la libertad y el determinismo, como si se negaran una idea a la otra, pero ¿por qué el determinismo es tan cerrado con la idea de la libertad?, ¿qué pasaría si el determinismo no fuera tan duro y admitiera a la libertad como parte del ser humano?, ¿cuál postura es más convincente en su forma de ver la libertad?

This article reviews the development of a new epistemic discourse in Latin America. Global modernity opens up a historical time of bifurcation and cognitive emergency, which confronts the hegemony of Eurocentric thinking. An episteme that expresses the profound historical changes of the modern mind-set.

La riqueza de una dimensión humana como la libertad merece el compromiso de cuidar de ella, y nuestra manera de atender a esta tarea pone a prueba el valor que le conferimos a nuestro propio ser. El pasar por alto este cometido se traduce en una experiencia de atropello, que termina por enrolarnos a todos en un interminable ciclo de hostilidad. Albert Camus nos ofrece una mirada que nos permite reconocer el mérito de ocuparnos de nuestro ser libre, sin (...) atribuirle a nuestra libertad un carácter absoluto bajo el que se esconde la intención de obtener un provecho sobre los demás. De manera que nuestra libertad se realiza en la medida en que nos proporciona un bien que no es monopolio de ninguno, al contrario, beneficia a cada quién en tanto que lo hemos alcanzado en conjunto.

El artículo propone algunos elementos del pensamiento de San Agustín que podrían abrirse a un diálogo fecundo con la ética contemporánea, tales como: el ser sí mismo capaz de ratio y veritas; la interioridad como (...) pilar último de la comunidad y de la sociedad; temporalidad y anhelo de felicidad; la experiencia del mal y la supremacía del bien; la tensión entre caritas y cupiditas; libertad y gracia; ciudadanía terrena y celeste.

Understanding the ways in which Muslims are turned into “a problem” requires an analytic incorporating the insights gained through the concepts of Islamophobia and anti-Muslim racism into a larger frame. The “Muslim Question” can provide such a frame by attending to the systematic character of this form of racism, explored here through biopolitics. This article develops a conceptualization of Europe’s “Muslim Question” along three lines. First, the “Muslim Question” emerges as an accusation of being an “alien body” to the nation, (...) often expressed through the Trojan horse legend. Second, the “Muslim Question” is elaborated through demands of integration and assimilation, in which the production of difference entangles with calls and measures to regulate Muslims. And third, the “Muslim Question” is brought to life upon the terrain of gender and sexuality, as the imaginary of threat at the heart of the “Muslim Question” is a replacement conspiracy centered on birthrates.

In this chapter we use methods of corpus linguistics to investigate the ways in which mathematicians describe their work as explanatory in their research papers. We analyse use of the words explain/explanation (and various related words and expressions) in a large corpus of texts containing research papers in mathematics and in physical sciences, comparing this with their use in corpora of general, day-to-day English. We find that although mathematicians do use this family of words, such use is considerably less prevalent (...) in mathematics papers than in physics papers or in general English. Furthermore, we find that the proportion with which mathematicians use expressions related to ‘explaining why’ and ‘explaining how’ is significantly different to the equivalent proportion in physics and in general English. We discuss possible accounts for these differences. (shrink)

Humility is increasingly recognized as an essential attribute for individuals at top management levels to build successful organizations. However, research on CEO humility has focused on how humble chief executive officers (CEOs) shape collective perceptions through their interactions and behaviors with other organizational members while overlooking CEOs’ critical role in making strategic decisions. We address this unexplored aspect of CEO humility by proposing that humble CEOs influence decision-making decentralization at the top management team (TMT) and subsequently promote an organizational ethical (...) culture. Using a sample of CEOs and TMT members from 120 small- and medium-sized enterprises, we find strong support for our hypotheses. We discuss important implications for research on CEO humility and strategic leadership. (shrink)

Tocqueville, como todos los grandes clásicos, es inagotable. A man for all seasons, como lo prueba su reciente éxito en China y Japón, dos países y dos sistemas políticos tan alejados de la historia europea y del modelo democrático que él describió que le hubiera parecido sorprendente que le utilizaran como referencia. Ser un clásico inagotable con solo dos obras de obligada lectura es un logro del que pocos pueden vanagloriarse. Quizá Hobbes, quizá John Locke, dos de los autores que (...) menciona Lucien Jaume en el primer artículo de este monográfico que presentamos en la revista Araucaria. (shrink)

Some authors have argued that consideration of alternative claims, theories, or worldviews is necessary for a proper or sound critical assessment of a claim or set of claims. However, an understanding of interpretation and beliefs as inherently holistic suggests that interpretation already involves the recogllition of alternatives, and that therefore assessment also necessarily involves their comparison. Starting from this idea, it will be argued that presuppositions can be regarded as limits to the range of alternatives that are considered by the (...) author of the claims, as seen by an interpreter making the assessment. However, a result of this consists in the fact that these assumptions can only be found in the conversational interaction between the author’s and the interpreter’s broader belief systems. Some implications for a conversational form of criticality will also be derived from here. (shrink)

El desarrollo de la actividad de estudio a partir de niveles de eficiencia cada vez mayores constituye un requisito indispensable para el tránsito de los estudiantes por la Educación Superior. De igual forma representa un reto para los docentes en el diseño del proceso enseñanza- aprendizaje. En este empeño es necesario prestar atención a los métodos, procedimientos y estrategias que permitan al estudiante la adopción de una posición reflexiva e independiente en la búsqueda del conocimiento, su actualización y aplicación en (...) la diversidad de tareas de estudio que como parte de su formación integral deben realizar. En ello resulta importante el análisis de las vías que favorecen un mejor funcionamiento de la memoria como proceso cognoscitivo fundamental. El presente artículo ofrece elementos teóricos y metodológicos esenciales que pueden servir de guía a docentes y estudiantes en la regulación y autorregulación de los procesos mnémicos desde la perspectiva del estudio eficiente, aspectos que no siempre son valorados en correspondencia con los aportes teóricos existentes. The development of the studying activity, based on ever growing efficiency levels, constitutes an indispensable requirement for the students' passing through higher education. Likewise, this fact represents a challenge for the professors to teach the students how to study. In doing so, it is necessary to pay attention to methods, procedures and strategies that allow the students to take a reflexive and independent position while searching for knowledge, its updating and application in the diversity of studying tasks which as a part of its integral formation the students have to accomplish. It is of uppermost importance the analysis of the ways that favor a better functioning of memory as a fundamental cognitive process. This article offers essential theoretical and methodological elements which may be guidelines to professors and students for regulating and self- regulating the memory processes from an efficient study perspective, which are not always valued in correspondence to the existing theoretical outcomes on the field.

Different proprietary databases have been used extensively in research to assess the environmental performance and environmental risk of companies. This study explores the convergent validity of the environmental ratings of MSCI ESG STATS, Thomson Reuters ASSET4 and Global Engagement Services. The study shows that the ratings have common dimensions, but on aggregate, they do not converge. On the environmental opportunity side, KLD environmental strengths, and ASSET4 and GES environmental performance metrics correlate highly and provide convergent scores for US companies from (...) 2003–2011. On the environmental risk side, KLD environmental concerns converge with the GES environmental industry risk and company emissions from the ASSET4 database. Further analysis confirms that industry-related risks are drivers of company-specific environmental performance. (shrink)

John L. Austin estableció desde su teoría de los actos de habla, que la persuasión es un acto perlocucionario, es decir, uno de los efectos producido por un hablante sobre otro mediante un discurso. Aristóteles ya había definido la retórica como la facultad de considerar en cada caso lo que cabe para persuadir. Aquí nos proponemos mostrar que para Aristóteles la persuasión se produce, ciertamente, por el discurso, pero que las pasiones también son necesarias para producirla. Si esto es así, (...) ellas deben poder expresarse mediante el lenguaje discursivo. Con el fin de demostrar lo anterior, vamos a proceder de la siguiente manera: Primero se señala la conexión que se establece entre persuasión y opinión, y de ésta con la palabra. Segundo, dado lo anterior, se precisa que además de que el hombre se comunica -algo que también hacen los animales-, también se expresa mediante el lenguaje discursivo. Finalmente, haremos la siguiente consideración: si mediante las pasiones se producen cambios en el cuerpo, y ellas mismas son sentidas por el alma, entonces, sobre ellas el hombre también podría construir enunciados.

En el libro II de la Retórica se encuentra un estudio sobre las pasiones, las cuales, como bien lo afirma Aristóteles, influyen en la formación del juicio y por tanto en la toma de decisiones; esto hace pensar en su posible incidencia en la conformación de las comunidades humanas, lo cual puede ser inicialmente abordado desde los vínculos que una retórica de las pasiones tiene con la política y con la ética. En la parte final de este artículo se muestra (...) la cercanía que puede existir entre el término de pasión utilizado por Aristóteles, y el sentimiento moral de P. Strawson y E. Tugendhat, con el fin de iniciar una reflexión sobre el valor que la retórica de las pasiones de Aristóteles puede tener en los estudios contemporáneos. (shrink)

Sympathy is a powerful principle in human nature, which can change our passions, sentiments and ways of thinking. For the 18th century Scottish philosopher David Hume, sympathy is a working mechanism accountable for a wide range of communication: the ways of interacting with the others’ affections, emotions, sentiments, inclinations, ways of thinking and even opinions. The present paper intends to find a systematic reading of Hume’s Treatise of Human Nature from the point of view of what the mechanism of sympathetic (...) communication implies in terms of strengthening our action of understanding, of being sensitive to, and vicariously experiencing the feelings, thoughts, and experience of others. Hume’s description of the sympathetic mechanism appears to suggest that sympathetic passions come upon us purely by natural means in a passive manner, without the active use of any of our faculties. Consequently, scholarly attention is drawn to the mechanistic character of the sympathetic process; its automatic nature is emphasized to such an extent that some experts even find it to be completely void of any reflective process. The current study investigates to what extent the sympathetic process can actively be modified and in what manner sympathetic feelings can be generated as described in Hume’s system of emotions. The paper identifies at which points the otherwise mechanically and passively operating process of sympathetic feelings is open to be modified by actively altering or strengthening certain skeletal points of the mechanism. I argue that the alterations can be initiated by the person who receives the sympathetic feelings and also by the person whose passions are transmitted, moreover even by a third party. In a seemingly mechanic model, there is room for altering or at least amplifying one’s sympathetic feelings. (shrink)

The issue of what constitutes a valid logical inference is a difficult question. At a minimum, we believe a permissible step in a proof must provide the reader with rational grounds to believe that the new step is a logically necessary consequence of previous assertions. However, this begs the question of what constitutes these rational grounds. Formalist accounts typically describe valid rules of inferences as those that can be found by applying one of the explicit rules of inference in the (...) formal system in which the proof is couched. However, philosophers of mathematics find such a description unhelpful because many inferences in the proofs that mathematicians actually produce cannot be expressed in a formal language, at least not without seriously distorting the semantic content of the inference (e.g., Larvor, 2012). In this chapter, we investigate mathematicians’ perceptions of a particular kind of inference in a particular setting. Specifically, we shed light on what types of graphical inferences mathematicians find permissible in a real analysis proof. Following Larvor (in press), we examine mathematicians’ reactions to metrical graphical inferences (i.e., inferences whose validity depends on the accuracy of the graph that was drawn and whose validity can be changed by minor deformations) and nonmetrical graphical inferences (i.e., inferences whose validity does not depend on a the accuracy of the graph and whose validity is not vulnerable to local deformations). The goal of this chapter is threefold. First, we demonstrate that most mathematicians reject metrical graphical inferences as impermissible in a real analysis proof. Second, we show that many mathematicians regard nonmetrical graphical inferences as permissible in a real analysis proofs. Third, we illustrate how mathematicians collectively disagree on the permissibility of nonmetrical inferences. (shrink)

Nursing is at the same time a vocation, a profession and a job. By nature, nursing is a moral endeavor, and being a ‘good nurse’ is an issue and an aspiration for professionals. The aim of our qualitative research project carried out with 18 nurse teachers at a university nursing school in Brazil was to identify the ethical image of nursing. In semistructured interviews the participants were asked to choose one of several pictures, to justify their choice and explain what (...) they meant by an ethical nurse. Five different perspectives were revealed: good nurses fulfill their duties correctly; they are proactive patient advocates; they are prepared and available to welcome others as persons; they are talented, competent, and carry out professional duties excellently; and they combine authority with power sharing in patient care. The results point to a transition phase from a historical introjection of religious values of obedience and service to a new sense of a secular, proactive, scientific and professional identity.

In this paper, we present a new questionnaire for the assessment of self-control as an individual trait. We describe the process of construction of this assessment tool. We also report the results of relevant validation studies. The questionnaire has two independent versions, one based on self-reports and another one based on other-reports. The first version consists of five subscales, called Initiative and Persistence, Proactive Control, Switching and Flexibility, Inhibition and Adjournment, and Goal Maintenance. Seven samples of participants took part in (...) the validation study. The second version has not been split into subscales. Both versions obtained satisfactory indices of internal consistency, assessed with Cronbach’s alpha. The NAS-50 and NAS-40 scores were highly correlated with other measures of self-control, including Tangney, Baumeister, and Boone’s self-control scale. They also proved to be entirely independent of general intelligence. In conclusion, both versions can be regarded reliable and valid enough, and therefore suitable for the assessment of trait self-control for research purposes. (shrink)

The existence of embodied communication in humans places them among other living systems and helps to differentiate sign patterns that are common to all bioforms from those that are peculiarly human. Despite the fact that the biological roots of communication have been proven, the understanding of human forms of discourse is still far from being clarified. The main question remains: when and why did humans acquire the ability to exchange messages via speech? My thesis is that it became possible only (...) after humans made a shift from on-line to off-line interaction and learned to communicate in the interpersonal mode via externalized analog codes that constitute the various forms of human culture.

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)

Mathematical explanations are poorly understood. Although mathematicians seem to regularly suggest that some proofs are explanatory whereas others are not, none of the philosophical accounts of what such claims mean has become widely accepted. In this paper we explore Wilkenfeld’s suggestion that explanations are those sorts of things that generate understanding. By considering a basic model of human cognitive architecture, we suggest that existing accounts of mathematical explanation are all derivable consequences of Wilkenfeld’s ‘functional explanation’ proposal. We therefore argue that (...) the explanatory criteria offered by earlier accounts can all be thought of as features that make it more likely that a mathematical proof will generate understanding. On the functional account, features such as characterising properties, unification, and salience correlate with explanatoriness, but they do not define explanatoriness. (shrink)
