The present article, more than to deepen in the polemic classic Popper - Kuhn regarding the progress of the science, seeks to indicate some fundamental pillars that should be kept in mind as possibility for the elaboration of a curriculum in the teaching of the sciences. It is rescued of this discus..

La Casa de las Gallinas perteneció a la realeza nazarí granadina, teniendo categoría de casa fuerte con carácter palaciego. Por ello, los Reyes Católicos adquirieron sus propiedades tras la conquista de la ciudad de Granada, incorporándola a la Alcaidía de la Alhambra. Hasta el siglo XIX siguió perteneciendo al Patrimonio Real, siendo durante mucho tiempo celosamente guardada por la Corona española, lo que no impidió que sus propiedades acabaran finalmente en manos de particulares. Hasta tal punto llegó a ser descuidada (...) su enajenación que, a lo largo del siglo XX, la ubicación exacta de sus restos arqueológicos fue cayendo en el olvido. El análisis detallado de los testimonios gráficos y documentales que de ella se han conservado, nos permitió localizar in extremis su emplazamiento. (shrink)

El objetivo que dirige este artículo es esbozar el modo en que, desde la filosofía para niños, es pensable un ejercicio crítico de la identidad y, a partir de ello, promover una revitalización del mundo político, entendido desde el concepto arendtiano de acción. Revelar los marcos referenciales y, una vez puestos de relieve, someterlos a una crítica dialógica, comunitaria, supone la posibilidad ―quizás utópica― de proyectar desde la niñez y construir a futuro un mundo digno de ser vivido. La metodología (...) utilizada es cualitativa, de corte hermenéutico. En el primer apartado se desglosa el concepto tayloriano de identidad en su vínculo con los marcos referenciales y la idea de bien. En el segundo acápite nos concentramos en el doble concepto arendtiano de mundo, como mundo circundante y como trama política. Finalmente, y tomando como punto de partida los análisis de Lipman, se esboza el carácter político de la filosofía para niños, entendiendo aquí lo político con Hannah Arendt. (shrink)

Deleuze, en el primer capítulo de Nietzsche y la Filosofía,1 introduce los recurrentes tópicos en las obras de Nietzsche: las relaciones entre fuerzas, y la voluntad de poder, con el objetivo de cuestionar la presencia de una dialéctica dentro del pensamiento nietzscheano.Pasajes en la obra de Nietzsche, labradores de una interpretación cuestionable acerca de la confrontación de fuerzas –como el apartado “De la superación de sí mismo” en el Así habló Zaratustra2–, donde se usan las palabras «órdenes», «seres obedientes», «juez» (...) y «vengador», hacen que el estudio de Deleuze se dirija por los caminos de una aceptable duda, como lo haría cualquier estudioso minucioso.Deleuze aborda este tema desde la perspectiva propia de un conocedor de Nietzsche como crítico de Hegel, tal como lo muestra la siguiente frase: «No entenderemos bien el conjunto de la obra de Nietzsche si no vemos “contra quién” van dirigidos los principales conceptos. Los temas hegelianos están presentes en esta obra como el enemigo que se combate». (shrink)

The aim of this article is to revisit Clement of Alexandria’s Paedagogus 2.5.45-8 discussing whether Clement holds a moderate position οf laughter or, like most early Christians, tends to an “antigelastic” position. Some scholars, such as Stephen Halliwell and Laura Rizzerio, have concluded that Clement holds an intermediate position between an optimistic approach to laughter and its condemnation. However, in this essay we argue that while Clement’s position is not a straightforward antigelastic one, his apparent acceptance of laughter is so (...) narrow that his moderate view ends up being compromised. Ultimately, he is strongly inclined to condemn laughter and to prescribe an ascetic life devoid of laughter. (shrink)

We argue that it is fundamentally impossible to recover information about quantum superpositions when a quantum system has interacted with a sufficiently large number of degrees of freedom of the environment. This is due to the fact that gravity imposes fundamental limitations on how accurate measurements can be. This leads to the notion of undecidability: there is no way to tell, due to fundamental limitations, if a quantum system evolved unitarily or suffered wavefunction collapse. This in turn provides a solution (...) to the problem of outcomes in quantum measurement by providing a sharp criterion for defining when an event has taken place. We analyze in detail in examples two situations in which in principle one could recover information about quantum coherence: (a) “revivals” of coherence in the interaction of a system with the measurement apparatus and the environment and (b) the measurement of global observables of the system plus apparatus plus environment. We show in the examples that the fundamental limitations due to gravity and quantum mechanics in measurement prevent both revivals from occurring and the measurement of global observables. It can therefore be argued that the emerging picture provides a complete resolution to the measurement problem in quantum mechanics. (shrink)

To explain globalization of the Mexicandairy production more precisely, globalization indairy systems worldwide and within Mexico ispresented, using an intensive dairy operation in theregion of La Laguna (North Mexico), and a traditionaldairy operation in Los Altos de Jalisco (West Mexico)as examples. The focus is on the economic aspects ofregionalization, and how it relates to theglobalization process. In this context, the process ofregionalization of the North American dairy systemsand their relationships with the local systems in LaLaguna and Los Altos de Jalisco (...) are presented. Themain thesis in this paper is whether globalization hasacted as a factor to help homogenize the dairy systemsin terms of economic, political, and culturalprocesses affected by world tendencies as well aslocal trends.

The objective of the communication is to analyze the characteristics of the training projects and their relationship with the development of collaborative work in Higher Education Institutions. As a study methodology, a documentary investigation was carried out, through the review and obtaining of information in various bibliographical sources. The results indicate that training projects are a strategy aimed at training people who, in a collaborative way and with the support of new technologies, are able to mobilize their knowledge in solving (...) their most pressing context problems, so they differ from traditional educational practices, in which knowledge are transmitted by the teacher in an academic manner. In conclusion, it is necessary to continue carrying out theoretical and empirical studies that enable the educational change required by the society of our time. (shrink)

Aunque el denominado problema de marco generó múltiples debates a finales del siglo pasado, aún es un problema fundamental para el avance en las Ciencias Cognitivas, en general, y para la Inteligencia Artificial, en particular. En este trabajo, y restringiéndonos al aspecto lógico del problema, postulamos que la discusión actual y subyacente a este aspecto gira en torno a cómo determinar lo que no cambia en términos de acciones y propiedades dentro de un sistema lógico formal. Es sobre este aspecto, (...) y en función de sus dificultades (i) definicional y (ii) resolutiva, que en este trabajo argumentaremos que el denominado “criterio temporal” no solamente puede estimarse como uno los principales requerimientos teóricos para (i) resolverlo sino también para (ii) explicitar más claramente su dificultad principal, a saber, “lo que es relevante” frente al cambio en el tiempo. De esta manera, sostenemos que el razonamiento lógico-temporal resulta necesario para construir cualquier solución íntegramente satisfactoria del aspecto lógico del problema de marco entendido como el modo en que, inmediatamente, determinamos relevancia frente al cambio.

Background. The study of entrepreneurial activity has undergone intense development in recent decades. Traditionally this topic has been addressed from three approaches: economic, sociological and psychological. In the study of enterprising personality, two fundamental perspectives stand out: the use of general personality traits, like the Big Five, and the use of more specific traits related to entrepreneurial spirit, such as self-efficacy, autonomy, innovation, optimism, and others. The objective of this study is to provide validity evidence for a new instrument for (...) measuring eight specific dimensions of entrepreneurial personality (BEPE). Method. The sample was composed of 1,170 adults from the general population (59.9% women). The average age was 42.34 years with a standard deviation of 12.96. Of the sample, 13% were self-employed. Internal factorial structure and reliability of BEPE were examined. The relationships with other variables and the discriminative capacity of the BEPE between different groups of workers were analyzed. Results. First order factor analyses show the essential unidimensionality of each of the eight proposed sub-scales, with factorial weights ranging between 0.341 and 0.825. A second-order factor analysis was carried out, obtaining a general dimension of entrepreneurial personality. With regards to reliability, the eight BEPE sub-scales gave high alpha coefficient values, between 0.825 and 0.899, as did the total battery (0.97). BEPE sub-scales show a high canonical correlation with the Big Five personality factors (.795), and with the sub-scales of the Measure of Entrepreneurial Talents and Abilities questionnaire (.815). Conclusions. The BEPE questionnaire for the evaluation of the eight fundamental specific dimensions of the entrepreneurial personality presents adequate psychometric properties. Its relationships with other measures of personality traits are in line with what is expected. Therefore, the BEPE is a new measurement instrument that can be used with confidence both in the applied field and in research. (shrink)

El comentario de texto es una práctica habitual en la enseñanza de la filosofía y de otras disciplinas. En general, los modelos existentes se centran en la comprensión del texto y del contexto del autor y la época, pero menos en la apropiación dialogada por parte del lector de los problemas a los que el texto hace frente. Basados en las aportaciones de algunas de las corrientes hermenéuticas más significativas del siglo XX, los autores fundamentan y exponen un modelo de (...) comentario de texto centrado en el diálogo establecido entre el lector y el texto.

As a result of the complexity inherent in some natural systems, mathematical models employed in ecology are often governed by a large number of variables. For instance, in the study of population dynamics we often find multiregional models for structured populations in which individuals are classified regarding their age and their spatial location. Dealing with such structured populations leads to high dimensional models. Moreover, in many instances the dynamics of the system is controlled by processes whose time scales are very (...) different from each other. For example, in multiregional models migration is often a fast process in comparison to the growth of the population.Approximate reduction techniques take advantage of the presence of different time scales in a system to introduce approximations that allow one to transform the original system into a simpler low dimensional system. In this way, the dynamics of the original system can be approximated in terms of that of the reduced system. This work deals with the study of that approximation. In particular, we work with a non-autonomous discrete time model previously presented in the literature and obtain different bounds for the error we incur when we describe the dynamics of the original system in terms of the reduced one.

In this work we extend approximate aggregation methods in time discrete linear models to the case of time varying environments. Approximate aggregation consists in describing some features of the dynamics of a general system involving many coupled variables in terms of the dynamics of a reduced system with a few number of variables. We present a time discrete time varying model in which we distinguish two time scales. By using perturbation methods we transform the system to make the global variables (...) appear and build up the aggregated system. The asymptotic relationships between the general and aggregated systems are explored in the cases of a cyclically varying environment and a changing environment in process of stabilization. We show that under quite general conditions the knowledge of the behavior of the aggregated system characterizes that of the general system. The general method is also applied to aggregate a multiregional time dependent Leslie model showing that the aggregated model has demographic rates depending on the equilibrium proportions of individuals in the different patches.

The relationships among character strengths (forgiveness and gratitude), happiness, and pro-social bystander behavior in bullying were analyzed. The sample includes 500 (early adolescents) and 500 (middle adolescents) of both genders, between 12 and 18 years old (M age = 14.70, SD = 1.58). Two structural equation models were calculated. Results of the first model indicated that forgiveness, gratitude, and happiness had a direct positive relation with pro-social bystander behavior. Furthermore, human strengths were indirectly related to prosocial behavior in bullying for (...) this effect in happiness. The second model showed that pro-social bystander behavior had a positive effect on human strengths and happiness. Multi-group analyses indicated that gender and stage of adolescence did not moderate the relations found in the model. Overall findings suggest a reciprocal relationship between character strengths, happiness, and pro-social bystander behavior. (shrink)
