Artificial neural networks, in interaction with fuzzy logic, genetic algorithms, and fuzzy neural networks, represent an example of a modern interdisciplinary field, especially when it comes to solving certain types of engineering problems that could not be solved using traditional modeling methods and statistical methods. They represent a modern trend in practical developments within the prognostic modeling field and, with acceptable limitations, enjoy a generally recognized perspective for application in construction. Results obtained from numerical analysis, which includes analysis of the (...) behavior of reinforced concrete elements and linear structures exposed to actions of standard fire, were used for the development of a prognostic model with the application of fuzzy neural networks. As fire resistance directly affects the functionality and safety of structures, the significance which new methods and computational tools have on enabling quick, easy, and simple prognosis of the same is quite clear. This paper will consider the application of fuzzy neural networks by creating prognostic models for determining fire resistance of eccentrically loaded reinforced concrete columns. (shrink)

We adopt the largest consistent set defined by Chwe (1994; J. Econ. Theory 63: 299–325) to predict which coalition structures are possibly stable when players are farsighted. We also introduce a refinement, the largest cautious consistent set, based on the assumption that players are cautious. For games with positive spillovers, many coalition structures may belong to the largest consistent set. The grand coalition, which is the efficient coalition structure, always belongs to the largest consistent set and is the unique one (...) to belong to the largest cautious consistent set. (shrink)

El enfoque socioeducativo de la educación, tal y como aquí lo hemos entendido, trata de agrupar y promover aquellas experiencias educativas que tienen como objetivo fortalecer la democracia y la ciudadanía participativa a través de una educación integral guiada por valores como la solidaridad, la igualdad y la justicia.

En las sociedades modernas, un gran número de las decisiones que nos afectan descansan en los datos registrados en ficheros informatizados que contienen informaciones sobre millones de personas relativas a un amplio número de facetas de su vida. Para garantizar la dignidad, libertad y el pleno ejercicio de los derechos fundamentales frente al uso torticero de las nuevas tecnologías de la información, el artículo 18.4 de nuestra Constitución ha establecido una nueva garantía constitucional denominada tradicionalmente autodeterminación informativa. Este nuevo derecho (...) es configurado por nuestro Tribunal Constitucional como un derecho fundamental autónomo aunque estrechamente ligado al derecho a la intimidad y un derecho instrumental de garantía de otros derechos fundamentales. El contenido de este derecho es desarrollado en la nueva Ley de Protección de Datos Personales, la Ley Orgánica 15/1999, de 13 de diciembre, que sin duda aporta interesantes y positivas novedades. Sin embargo, al igual que sucedía en el caso de la L. O. 5/1992 LORTAD, siguen existiendo demasiadas sombras que pueden afectar al contenido esencial del derecho a la autodeterminación informativa y que impiden que efectivamente éste pueda cumplir su misión de garantizar la dignidad y la libertad de las personas en las nuevas sociedades de la información.

Derrida muestra con agudeza el conjunto de paradojas que es preciso experimentar para exponer la política a su límite, es decir, a su (im)posibilidad. Pero, ¿alberga el concepto de hospitalidad-don algún tipo de esperanza para pensar y concebir una política diferente? ¿Abre la teoría derrideana algún espacio para la libertad, a partir de la denuncia de la estructura sacrificial comprometida en toda identidad? Como se mostrará a lo largo de este trabajo, una respuesta que haga justicia al pensamiento derrideano sólo (...) puede decir «sí y no» al mismo tiempo, moviéndose alternadamente en el terreno de lo posible y de lo imposible.

Este estudo pretende discutir as relações existentes entre mídia e educação, analisando as políticas públicas que influenciaram a criação da TV Pendrive, identificando a percepção dos professores acerca da mesma. Justifica-se pelo fato de que no ano de 2007 o governo federal criou o Programa Nacional de Tecnologia Educacional (ProInfo), com o objetivo de informatizar o ensino, buscando promover uma educação com maior qualidade. Nesse contexto, a Secretaria de Estado da Educação do Paraná, com vistas à inclusão e ao acesso (...) de alunos e professores da rede pública estadual às novas tecnologias, criou o projeto TV Pendrive. Para a concretização desse estudo, foram realizadas pesquisas e análises bibliográficas, bem como um levantamento com professores da educação básica pública estadual da cidade de Londrina/PR, visando a identificar a percepção dos mesmos em relação à TV Pendrive. Como resultado, constatou-se que as políticas públicas, especialmente as voltadas à educação, parecem ser implantadas pelo governo sem a anuência dos educadores. (shrink)

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.

The business world is facing a very complicated situation due to the COVID-19 pandemic. Small- and medium-sized companies —both in Spain and at the global level—are seeing their survival jeopardized by a fall in revenues. This scenario is aggravated in the case of micro-SMEs headed by female entrepreneurs. Accordingly, micro-SMEs, particularly those led by female entrepreneurs, need to reinvent themselves to overcome the current adversities that could lead to the destruction of their businesses and hence their jobs. One of the (...) ways to do this is to take advantage of digital transformation. Therefore, the aim of this paper is to analyze which variables influence the financial results of female-led Spanish micro-SMEs when they carry out social marketing actions. For that purpose, an online survey was designed and analyzed using the “PROCESS” macro. Results show that social media marketing actions have significant effects on financial performance. (shrink)

Los avances de la biotecnología y las fascinantes perspectivas de la genómica nutricional en el escenario de la práctica clínica conducen a la consideración de distintos aspectos que impactan en el beneficio integral del ser humano. En ese sentido, la integración de la nutrición personalizada en la atención clínica requiere de un análisis bioético centrado en la unidad de la persona que, con base en su perfil nutrigenético único, contribuya al cuidado de la salud por medio del tratamiento nutricional individualizado. (...) El análisis bioético contempla los principios de totalidad terapéutica, libertad e integridad. Además, el uso de las pruebas nutrigenéticas destaca no solo la confidencialidad de datos, que se presupone, sino que lleva a considerar el derecho a la intimidad. (shrink)

University program dropout is a problem that has important consequences not only for the student that leaves but also for the institution in which the withdrawal occurs. Therefore, higher education institutions must study the problem in greater depth to establish appropriate prevention measures in the future. However, most research papers currently focus primarily on the characteristics of students who leave university, rather than on those who choose to pursue alternative courses of study and therefore fail to take into account the (...) different kinds of abandonment. The aim of this paper is to identify the different types of dropout to define their characteristics and propose some recommendations. Thus, an ex post facto study was carried out on a sample of 1,311 freshmen from a university in the north of Spain using data gathered using an ad-hoc designed questionnaire, applied by telephone or an online survey, and completed with data available in the university data warehouse. A descriptive analysis was performed to characterize the sample and identify five different groups, including 1. Students persisting in their initiated degree 2. Students who change of program (within the same university) 3. Students transferring to a different university 4. Students enrolling in non-higher-education studies 5. Students that quit studying. Also, data mining techniques (decision trees) were applied to classify the cases and generate predictive models to aid in the design of differentiated intervention strategies for each of the corresponding groups.

One of the most characteristic features of Comparative Literature in terms of methodological practice is that of operating in “in between” spaces. Not only does this feature suggest the comparative approach as something which originates through movement, thus making it imperative for the researcher to deal with the notion of mobility, it also characterizes many of the concepts with which it operates. Considering the possibility, as well as the fertility, of practicing this methodology in the analysis and critique of contemporary (...) visual art, we understand that it fits the analysis of any enterprise regarding the in-betweens of visual and verbal texts. These fundamental aspects were elected for a comparative analysis of two visuals artists whose œuvres operate in in-between spaces between the visual and the verbal as much as between the self and the Other. José Leonilson (Brazil 1957-1993) and Louise Bourgeois (France/EUA 1911-2010) reveal, through a comparative analysis, creative and constitutive actions which elaborate a space we could best understand through the image of a seaside landscape where the line we try to draw to divide the saltwater from the sand never stands. But, in what manners could the constituted poetic space created by them be of significance for a broader spectrum than the literary interest? In our understanding, Leonilson’s and Bourgeois’s poetics operate through a silent hearing of the Other, might that be their loved ones, the stone or cloths. This conceptual notion, required for the creative action, thus establishes a particular notion of balance between them and the Other. It is this precise aspect that also operates the mobility of the notion of love through their œuvre, and through the election of personal emotional narratives as the thriving force for creation. And what could be more needed nowadays, here as elsewhere, than considering together with Leonilson’s and Bourgeois’ images that love shall be the perpetual moving space that at times nears, and later distances us from each other?

Jane Addams (1860-1935), activista y pensadora feminista estadounidense, nos permite reencontrarnos con una perspectiva del feminismo de antaño. Su trabajo intelectual como escritora y filósofa pragmatista fue muy influyente para el sufragio en Estados Unidos y la creación de leyes que buscaban mejorar las condiciones laborales de las mujeres y poblaciones afrodescendientes. También fue cofundadora de la primera residencia social de Estados Unidos que apoyó la población inmigrante europea, conocida como la Hull-House. Además de ser la primera mujer en la (...) Universidad de Yale en recibir un Master of Arts honorario, también fue la primera mujer ganadora del premio Nobel de la Paz en 1931.

Jane Addams es relevante actualmente porque puede sumarse a las voces que configuran el diálogo sobre la prostitución. (shrink)

This article presents a review of the theoretical support of the Portfolio of Evidence as a pedagogical tool to be used at the higher level with the aim of improving writing products, understanding the importance of developing in students’ skills for the optimal construction of academic writings. The portfolio then becomes a resource used by teachers not only to obtain evidence of the progress of students in the subject that is developed, but also constitutes an indicator to assess the progress (...) in the acquisition of learning in the studentfrom the writings it produces. The particularity of being continuous and progressive also allows the student to self-assess their progress through the writing they make and can generate strategies for continuous improvement.
