El presente artículo aborda las connotaciones y los fundamentos de la paráfrasis cum canere vellem en Serv. Ecl. 6. 3. El análisis del sentido del verbo volo en este contexto y la confrontación del pasaje con Serv. Ecl. 6. 5 revelan que Servio interpreta la frase cum canerem reges et proelia como referencia a un temprano empeño de Virgilio en componer poesía épica, del que pronto desistió. Esta interpretación está condicionada por la idea de que la secuencia cronológica Églogas - (...) Geórgicas - Eneida tiene un correlato jerárquico, idea que se funda en noticias biográficas y en la teoría de la tripertita varietas. This paper focuses on the connotations and grounds of the paraphrase cum canere vellem in Serv. Ecl. 6. 3. The analysis of the sense of verb volo within this context, as well as the confrontation between that passage and Serv. Ecl. 6. 5, show that Servius interprets the clause cum canerem reges et proelia as a reference to Virgil's early endeavor to compose an epic poem, from which he shortly desisted. This interpretation is conditioned by the idea that the chronological sequence Eclogues - Georgics - Aeneid has a hierarchical correlate, an idea which is founded on biographical information and the theory of tripertita varietas.

A partir de las deficiencias detectadas en la evaluación de los objetivos educativos en la asignatura Morfofisiología I de la carrera de Estomatología, determinadas en un estudio previo realizado en la Facultad de Estomatología de Camagüey, se diseñó una metodología para facilitar a los docentes indicadores que les permitan considerar los objetivos educativos dentro de la evaluación final de los estudiantes. Se incluyen etapas, procedimientos y pasos para la instrumentación de la misma. Se considera que la misma facilitará un juicio (...) de valor más objetivo respecto al cumplimiento de los objetivos educativos. Starting from the analysis of the difficulties found in the evaluation of the educative objectives of the subject Morphophysiology I in the dental career, the findings were taken from a previous study carried out in the dental faculty in Camagüey a methodology was designed to give teacher's parameters to include the educative objectives within the final evaluation of the students. Stages, procedures and steps have to be followed to put it into practice. Its implementation is considered to give a better judgment in the fulfillment of the educative objectives. (shrink)

We present a new approach to the mathematical objects of General Relativity in terms of which a generic f(R)-gravity theory gravitation is written in a first-order (à la Palatini) formalism, and introduce the concept of Dark Metric which could bypass the emergence of disturbing concepts as Dark Energy and Dark Matter. These issues are related to the fact that General Relativity could not be the definitive theory of Gravitation due to several shortcomings that come out both from theoretical and experimental (...) viewpoints. At large scales, the attempts to match it with the recent observational data lead to invoke Dark Energy and Dark Matter as the bulk components of the cosmic fluid. Since no final evidence, at fundamental level, exists for such ingredients, it could be useful to reconsider the gravitational sector in order to see if suitable extensions of General Relativity could solve the shortcomings present at infrared scales.

Este artigo é um diálogo com Hegel e Gadamer, partindo da pergunta: "O que é arte?''. Hegel é um divisor de águas; pode-se dizer que a arte antes de Hegel é uma coisa e depois de Hegel outra. Com Hegel diremos que a arte "morreu" ou foi supra assumida pelo espírito absoluto; se isso não significa morte, é, pelo menos, perda de identidade - de autonomia. Com Gadamer diremos que a arte é arte, sem estar dizendo uma tautologia; pois essa (...) seria a melhor forma de dizer que arte não tem conceito e nem depende de conceito para ser arte; a arte é enquanto tal, sem pendências e sem dependências.

The balance between births and deaths in an age-structured population is strongly influenced by the spatial distribution of sub-populations. Our aim was to describe the demographic process of a fish population in an hierarchical dendritic river network, by taking into account the possible movements of individuals. We tried also to quantify the effect of river network changes (damming or channelling) on the global fish population dynamics. The Salmo trutta life pattern was taken as an example for.We proposed a model which (...) includes the demographic and the migration processes, considering migration fast compared to demography. The population was divided into three age-classes and subdivided into fifteen spatial patches, thus having 45 state variables. Both processes were described by means of constant transfer coefficients, so we were dealing with a linear system of difference equations. The discrete case of the variable aggregation method allowed the study of the system through the dominant elements of a much simpler linear system with only three global variables: the total number of individuals in each age-class.

In this review paper, we discuss how gravity and spin can be obtained as the realization of the local Conformal-Affine group of symmetry transformations. In particular, we show how gravitation is a gauge theory which can be obtained starting from some local invariance as the Poincaré local symmetry. We review previous results where the inhomogeneous connection coefficients, transforming under the Lorentz group, give rise to gravitational gauge potentials which can be used to define covariant derivatives accommodating minimal couplings of matter, (...) gauge fields (and then spin connections). After we show, in a self-contained approach, how the tetrads and the Lorentz group can be used to induce the spacetime metric and then the Invariance Induced Gravity can be directly obtained both in holonomic and anholonomic pictures. Besides, we show how tensor valued connection forms act as auxiliary dynamical fields associated with the dilation, special conformal and deformation (shear) degrees of freedom, inherent to the bundle manifold. As a result, this allows to determine the bundle curvature of the theory and then to construct boundary topological invariants which give rise to a prototype (source free) gravitational Lagrangian. Finally, the Bianchi identities, the covariant field equations and the gauge currents are obtained determining completely the dynamics. (shrink)

Resumen. La consideración de una nueva visión para sustituir y revisar las concepciones humanasen relación con el ambiente, plantea necesariamente mantener una misión educativa, dirigiendo laatención al complejo mundo natural, porque bajo esta perspectiva, educar representa una formaviable entre la realidad y el medio, condición indispensable para replantear la promoción de lasactividades ecológicas mediante el panorama gerencial, bajo el rol que desempeña el gerente deaula, para obtener cambios en el futuro posicionamiento humano en relación con la naturaleza. Elestudio tiene como (...) objetivo describir el rol gerencial del docente para la promoción de lasactividades ecológicas en la educación primaria. Tomando como caso el Colegio Jorbalán y EscuelaBásica San José, San Cristóbal, República Bolivariana de Venezuela. El estudio se fundamentó en laactividad promovida por el docente en cuanto a la participación ciudadana y el trabajo colaborativo,así mismo, la gerencia estratégica con referencia a la planificación, organización y dirección deactividades ecológicas. La investigación presentada es de nivel descriptivo, de campo, proyectofactible. Los resultados obtenidos indicaron, que los docentes promueven actividades departicipación ciudadana sobre acciones proambientales y valores ambientales; argumento del cualdiscreparon estudiantes y padres; también se detectaron deficiencias en el desarrollo de la gerenciaestratégica, concluyendo que el trabajo es importante porque hay necesidad de diseñar técnicas parala promoción de actividades ecológicas. Recomendando a los docentes como protagonistasmotivacionales, el ejercicio de los principios gerenciales con mayor firmeza a fin de mejorar lacalidad de vida.Palabras claves. Gerente de aula, promoción actividades ecológicas. Considering a new vision to replace and check the human conceptions in relation to theenvironment, necessarily arises maintain an educational mission, drawing attention to the complexnatural world, because from this perspective, education is a viable way between reality and theenvironment , which is essential to reconsider the promotion of environmental activities bymanagement scenario, in the role played by the manager class, for change in the future positioning inrelation to human nature. The study aimed to describe the managerial role of teachers in thepromotion of environmental activities in primary education. Case: Jorbalán College ElementarySchool and San Jose, San Cristobal, Bolivarian Republic of Venezuela.

Este artigo é uma tentativa de mostrar, a partir de Gadamer, que o Mito está em estreita relação dialética com o Logos e que a compreensão de ambos pertence a um mesmo movimento circular e hermenêutico, que conecta os conceitos de indeterminado e determinada, incerto e certo, infinitude e finitude.

E. S. de Beer's eight-volume edition of the correspondence of John Locke is a classic of modern scholarship. The intellectual range of the correspondence is universal, covering philosophy, theology, medicine, history, geography, economics, law, politics, travel and botany. This first volume covers the years 1650 to 1679. 'When the eight volumes of correspondence have appeared they will be recognized as one of the great scholarly achievements of their day.' K. H. D. Haley, Times Literary Supplement.

Borsboom and colleagues have recently proposed a “network theory” of psychiatric disorders that conceptualizes psychiatric disorders as relatively stable networks of causally interacting symptoms. They have also claimed that the network theory should include non-symptom variables such as environmental factors. How are environmental factors incorporated in the network theory, and what kind of explanations of psychiatric disorders can such an “extended” network theory provide? The aim of this article is to critically examine what explanatory strategies the network theory that includes (...) both symptoms and environmental factors can accommodate. We first analyze how proponents of the network theory conceptualize the relations between symptoms and between symptoms and environmental factors. Their claims suggest that the network theory could provide insight into the causal mechanisms underlying psychiatric disorders. We assess these claims in light of network analysis, Woodward’s interventionist theory, and mechanistic explanation, and show that they can only be satisfied with additional assumptions and requirements. Then, we examine their claim that network characteristics may explain the dynamics of psychiatric disorders by means of a topological explanatory strategy. We argue that the network theory could accommodate topological explanations of symptom networks, but we also point out that this poses some difficulties. Finally, we suggest that a multilayer network account of psychiatric disorders might allow for the integration of symptoms and non-symptom factors related to psychiatric disorders and could accommodate both causal/mechanistic and topological explanations.
