La gestión del aprendizaje es una obra que refleja el quehacer educacional de los educadores que tienen la responsabilidad de formar al ser humano en la sociedad del conocimiento, bajo la óptica de la educación críti-reflexiva que permita al humano insertarse en la sociedad eficientemente. La condición cambiante del mundo contemporáneo hace que el concepto de aprendizaje tome una dimensión más amplia y que se maneje en función del cambio en el significado de la experiencia, para que puedan desarrollarse los (...) humanos con comportamientos a la altura de los tiempos en que vivimos y no a los anteriores, en que el aprendizaje era el símbolo del que más sabía. El aprendizaje es hoy algo que esta en estrecha vinculación con la formación cognitiva, afectiva, valórica y motriz, a partir de la visión holística que se requiere para poder mirar los fenómenos desde una óptica más global que nos permita ver el proceso ante nosotros como una complejidad justo en la medida de lo que es. La gestión del aprendizaje es lo que se requiere para lograr estos propósitos. (shrink)

Huge losses and serious threats to ecosystems are common consequences of forest fires. This work describes a forest fire controller based on fuzzy logic and decision-making methods aiming at enhancing forest fire prevention, detection, and fighting systems. In the proposal, the environmental monitoring of several dynamic risk factors is performed with wireless sensor networks and analysed with the proposed fuzzy-based controller. With respect to this, meteorological variables, polluting gases and the oxygen level are measured in real time to estimate the (...) existence of forest fire risks in the short-term and to detect the recent occurrence of fire outbreaks over different forest areas. Besides, the Analytic Hierarchy Process method is used to determine the level of fire spread, and, when necessary, environmental alerts are sent by a Web service and received by a mobile application. For this purpose, integrity, confidentiality, and authenticity of environmental information and alerts are protected with implementations of Lamport’s authentication scheme, Diffie-Lamport signature, and AES-CBC block cipher.

The use of wireless sensor networks and the Internet of things to detect forest fire outbreaks may help to reduce the response time and avoid natural disasters. This work proposes the deployment of WSN to enhance the real-time monitoring of dynamic variables such as polluting gases, temperature or the presence of fire flames by infrared. In addition, the activation of forest fire alerts if environmental status may involve evidence of a recent fire outbreak. A fuzzy-based controller is implemented to manage (...) the uncertainty related to estimating forest fire occurrence and dynamic update of fuzzy sets is developed to distinguish usual and unusual environmental conditions of every monitored forest area. Merkle trees, AES and hash functions are considered to protect the integrity of environmental data. (shrink)

Pan es un dios peculiar en muchos aspectos. Al contrario que los restantes dioses del panteón griego, él no es antropomorfo, sino que tiene patas, cola y cuernos de carnero. Un dios con características tan arcaicas sólo puede sobrevivir confinado a la Arcadia, una región que conserva numerosos arcaísmos religiosos. Sin embargo, a partir del 490 a.C. en que se instaura su culto en Atenas, el dios comienza a cambiar. En su evolución, Pan se asimila cada vez más a Dioniso. (...) El acercamiento entre ambas figuras deja su huella en el mito, pero sobre todo en el culto. Así, un dios que en Arcadia era venerado en santuarios construidos por la mano del hombre, en el resto de Grecia recibe culto en parajes agrestes, fundamentalmente cuevas. No parece casual el hecho de que también fuera de Arcadia la gruta sea el lugar reservado a los cultos mistéricos, incluidos los dionisíacos Pan is a god peculiar in many respects. In contrast to the other gods of the Greek pantheon, he is not anthropomorphic, but he has the legs, tail and horns of a goat. These features show his age. A god like Pan can only survive in Arcadia, a region that preserves many religious archaisms. However, from 490 BC, when his cult is established in Athens, this god begins to change. In his evolution, Pan becomes increasingly assimilated the god Dionysus. The rapprochement between the two gods left his mark on the mythology, but especially in the cult of Pan. Thus, a god who was worshiped in Arcadia in sanctuaries built by men, in the rest of Greece is worshiped in wild shrines, mainly caves. Out of Arcadia, the grotto also is the place reserved for the mystery cults, including the Dionysian ones. Does not seem a coincidence. (shrink)

La disfasia es un término que conceptualiza una entidad gnoseológica relacionada con la organización del lenguaje en su evolución. Es un trastorno grave y de prolongada duración que afecta a niños desde el inicio del desarrollo del lenguaje, se extiende a toda la infancia y la adolescencia y puede dejar secuelas en el estado adulto. En esta revisión bibliográfica se propone un acercamiento a la comprensión de sus dimensiones, concepto, síntomas y pautas para el diagnóstico e intervención desde el enfoque (...) de la Comunicación. Dysphasia is a term that conceptualizes a gnoseologic entity related to the organization of language in its evolution. It is a severe and prolonged duration disorder that affects children since the beginning of the language development and extends to all children and adolescents; it can also leave consequences in the adult stage. This review proposes an approach to the understanding of its dimensions, concept, symptoms and guidelines for the diagnosis and involvement from a communication perspective. (shrink)

We designed an experiment to explore the learning effectiveness of three different ways of practicing dance movements. To our surprise we found that partial modeling, called marking in the dance world, is a better method than practicing the complete phrase, called practicing full-out; and both marking and full-out are better methods than practicing by repeated mental simulation. We suggest that marking is a form of practicing a dance phrase aspect-by-aspect. Our results also suggest that prior work on learning by observation (...) and learning by mental practice may not scale up to complex movements. (shrink)

RESUMEN El presente trabajo de revisión expone cómo las prácticas de gestión en la anestesiología deben ser modificadas para encarar las cambiantes necesidades de pacientes, otros profesionales y sistemas sanitarios, a fin de mantener una función significativa en la atención sanitaria. Los servicios de anestesia han adoptado una amplia variedad de modelos para hacer frente a las necesidades del medio local, la relación entre los anestesiólogos y la comunidad, y los papeles desempeñados por los anestesiólogos en el tratamiento perioperatorio. El (...) sistema sanitario cubano se encuentra inmerso en un proceso de permanente adecuación de sus servicios a los problemas, demandas y necesidades de la población cubana y sus determinantes. Por ello, objetivo es exponer consideraciones teóricas en función del perfeccionamiento del servicio de Anestesiología y Reanimación. ABSTRACT This review paper presents how anesthesiology management practices must be modified in order to deal with the changing needs patients, other professionals and health systems have, in order to maintain a significant function in health care. Anesthesiology services have adopted a wide variety of models to face up to the needs the city, the relationship between anesthesiologists and the community and the role anesthesiologists play in perioperative treatment have. The Cuban health system services are in a process of permanent adaptation to the problems, demands and needs the Cuban population and its determinants have. For that reason, this paper aims at presenting theoretical considerations towards the improvement of the Anesthesiology and Resuscitation service. (shrink)

Al cumplirse en este año el siglo de la despedida del Beato Manuel González de la diócesis de Huelva, ¿tienen todavía algo que decirnos su pensamiento y su actividad pastoral? Los tiempos de don Manuel no son los nuestros, ciertamente. El estilo de sus escritos y determinados elementos propios de su acción pastoral responden a las necesidades y espíritu de su época. Pero, a poco que se profundice en su obra, se descubren intuiciones de permanente actualidad e incluso de progreso. (...) El artículo presenta los elementos permanentes de la pastoral de don Manuel González en Huelva, sin olvidar la totalidad de su peripecia humana, sacerdotal y episcopal. (shrink)

Resumen: Este trabajo investiga las traducciones realizadas por Aphra Behn a partir de la clasificación tripartita que estableció John Dryden entre metáfrasis, paráfrasis e imitación. Behn cultiva la metáfrasis principalmente en sus traducciones de La Rochefoucauld, la paráfrasis en las versiones de Cowley o Tallemant, entre otros; mientras que aplica la imitación a las Fábulas de Esopo. Se constata que Behn rompe con la tradición de traducir principalmente a los autores clásicos, ensanchando los cauces de entrada de literatura moderna en (...) Inglaterra y ampliando las posibilidades de la traducción literaria. Analizando unas muestras, se infiere la manipulación del texto original que la autora realiza en ocasiones, en consonancia con su ideario creativo, generando un texto meta provisto de nuevas resonancias de género y políticas contextualizadas en su época. Asimismo, se deduce que la escritora profesional de la Restauración cultiva la traducción movida, entre otros motivos, por los gustos del naciente mercado literario en cuanto a las novedades del país galo y, por tanto, motivada por un afán comercial.: This paper examines the translations by Aphra Behn based on the tripartite classification that John Dryden established between metaphrase, paraphrase and imitation. Behn employs mainly metaphrase in her translations of La Rochefoucault; paraphrase in her versions of Cowley and Tallemant, among others; while applying the imitation to Aesop's Fables. It is found that Behn breaks with the tradition of translating principally classical authors, broadening channels for the entrance of modern literature into England and expanding the possibilities of literary translation. Analyzing the samples, the author's occasional manipulation of the original text is identified, consonant with her creative ideas and generating a metatext featuring new political and gender resonances contextualized in her era. It is also concluded that the professional writer of the Restoration employs translation spurred by the tastes of the burgeoning literary market, among other factors, shaped by recent developments in France and, as such, motivated by commercial interests.

Cognitive dysfunction in Alzheimer’s disease is caused by disturbances in neuronal circuits of the brain underpinned by synapse loss, neuronal dysfunction and neuronal death. Amyloid beta and tau protein cause these pathological changes and enhance neuroinflammation, which in turn modifies disease progression and severity. Vagal nerve stimulation, via activation of the locus coeruleus, results in the release of catecholamines in the hippocampus and neocortex, which can enhance synaptic plasticity and reduce inflammatory signalling. Vagal nerve stimulation has shown promise to enhance (...) cognitive ability in animal models. Research in rodents has shown that VNS can have positive effects on basal synaptic function and synaptic plasticity, tune inflammatory signalling, and limit the accumulation of amyloid plaques. Research in humans with invasive and non-invasive VNS devices has shown promise for the modulation of cognition. However, the direct stimulation of the vagus nerve afforded with the invasive procedure carries surgical risks. In contrast, non-invasive VNS has the potential to be a broadly available therapy to manage cognitive symptoms in early AD, however, the magnitude and specificity of its effects remains to be elucidated, and the non-inferiority of the effects of non-invasive VNS as compared with invasive VNS still needs to be established. Ongoing clinical trials with healthy individuals and patients with early AD will provide valuable information to clarify the potential benefits of non-invasive VNS in cognition and AD. Whether invasive or non-invasive VNS can produce a significant improvement on memory function and whether its effects can modify the progression of AD will require further investigation. (shrink)

Epistemological disjunctivism is a philosophical theory that has received special attention in the recent years. Particularly because it has been seen by many as a way of renewing discussions that range from the nature of justification of our daily beliefs to the possibility of unveiling the structure of the problem of radical skepticism and of responding to it. Duncan Pritchard is one of the authors who have offered a particular view of disjunctivism and ways of conceiving of disjunctivist treatments to (...) such questions. His work has as its main source of inspiration the seminal work of John McDowell. In this paper, I present a way of understanding the problem ofradicalskepticism and the mannerin which epistemological disjunctivism aimsto offer solutionsto it. In orderto do that, I present McDowell’s general proposal and discuss in which way his account differs from Pritchard’s own disjunctivism. At the end, I try to show how Pritchard’s approach tries to respond to radical skepticism not only by appealing to a disjunctivist reading of our epistemic position, but also by offering a revision of our structure of reasons.

We study an alternative embedding of IPC into atomic system F whose translation of proofs is based, not on instantiation overflow, but instead on the admissibility of the elimination rules for disjunction and absurdity. As compared to the embedding based on instantiation overflow, the alternative embedding works equally well at the levels of provability and preservation of proof identity, but it produces shorter derivations and shorter simulations of reduction sequences. Lambda-terms are employed in the technical development so that the algorithmic (...) content is made explicit, both for the alternative and the original embeddings. The investigation of preservation of proof-reduction steps by the alternative embedding enables the analysis of generation of “administrative” redexes. These are the key, on the one hand, to understand the difference between the two embeddings; on the other hand, to understand whether the final word on the embedding of IPC into atomic system F has been said.

Aiming at a better understanding of the extent to which Africa-focused research has helped develop context-bound, context-specific, and context-free knowledge, the authors present the findings from a literature review of journal articles with an African context. A systematic search resulted in 271 articles with African data and 139 Africa-focused articles published in 63 top business journals and related disciplines from 2010 onwards. The sample included all journals belonging to the University of Texas Dallas and Financial Times research rankings, as well (...) as the main international business, and business and society outlets. An in-depth analysis of the 139 Africa-focused articles shows an important imbalance in terms of publication patterns, topics covered, theoretical groundings, types of contributions, approaches to the African contexts, and empirics. Building on this exhaustive literature review, the authors provide specific suggestions regarding potential data sources and empirical strategies in African contexts, propose avenues for future research, and introduce four recent studies included in the special issue.

En este artículo se parte de la asunción común de que los ordenamientos jurídicos modernos exigen que las decisiones judiciales deben ser fundamentadas. Algunos filósofos del derecho, partiendo de esta exigencia práctica, han desarrollado diversas propuestas teóricas para explicar la estructura y el funcionamiento de las decisiones judiciales, pero también para ofrecer criterios de valoración que permitan determinar si cierta decisión judicial se encuentra propiamente justificada. En este artículo, en primer lugar, se reconstruyen algunas de estas propuestas teóricas y se (...) clasifican en dos modelos diferentes: la teoría estrecha del silogismo judicial y la teoría amplia del silogismo judicial. En segundo lugar, se explicita un complicado problema que aqueja a estos modelos, a saber, la paradoja del seguimiento de reglas. En tercer lugar, se propone una manera de disolver este espinoso problema y, a su vez, de dar un paso adelante en la construcción de una nueva línea explicativa, que aquí llamaré “teoría pragmatista de las decisiones judiciales”. Por último, se ofrece una manera plausible de acomodar conceptualmente los aportes teóricos más relevantes de cada uno de los tres enfoques. (shrink)

We leverage insights and theories from the extensive inter-firm alliance literature to explore the effect of the sector of the partners on Firm–NGO alliance governance. Our analysis suggests that the sector of the partners has an important impact on alliance governance, not only because it constrains the availability of some governance mechanisms but also because it makes alternative mechanisms available or relevant to the partners. Specifically, we predict that B2N alliances will rely on contracts, a restricted scope, and non-equity hostages, (...) such as reputational hostages and stakeholder involvement, rather than equity, leading to limited protection against opportunism. As a consequence, B2N alliance partners will need to rely on trust-based governance mechanisms to a greater extent than B2B alliance partners, although trust will be harder to build in B2N alliances.

En este trabajo se analiza la cuestión de la ontología y metafísica de las normas jurídicas, i.e., qué tipo de entidades son las normas jurídicas y cómo estas entidades adquieren existencia. Con respecto a la primera pregunta, se rechazan las posiciones que sostienen que las normas jurídicas sean: (i) entidades abstractas e independientes de otras entidades, o (ii) entidades concretas y dependientes de otras entidades. En cambio, se defiende que las normas jurídicas son entidades abstractas y dependientes de otras entidades. (...) En cuanto a la segunda pregunta, se rechazan las posiciones que sostienen que dicha relación de dependencia sea correctamente explicada por (i) la noción de causalidad o (ii) por la noción de superveniencia. En cambio, se defiende que esta relación de dependencia es correctamente explicada por una noción liberal de fundamentación (grounding). (shrink)

This essay, written in memory of Erik Olin Wright, considers Wright’s project of constructing and identifying real utopias. It confronts a tension in Wright’s oeuvre, the question of the knowledge by means of which reformers can identify the utopias that ground the really existing real utopias.

Graphical displays of simple moving geometrical figures have been repeatedly used to study the attribution of animacy in human observers. Yet little is known about the relevant movement characteristics responsible for this experience. The present study introduces a novel parametric research paradigm, which allows for the experimental control of specific motion parameters and a predictable influence on the attribution of animacy. Two experiments were conducted using 3D computer animations of one or two objects systematically introducing variations in the following aspects (...) of motion: directionality, discontinuity and responsiveness. Both experiments further varied temporal kinematics. Results showed that animacy experience increased with the time a moving object paused in the vicinity of a second object and with increasing complexity of interaction between the objects . The experience of animacy could be successfully modulated in a parametric fashion by the systematic variation of comparably simple differential movement characteristics. (shrink)

Stem cells have the capacity both to self‐renew and to give rise to differentiated progeny, and are vital to the organization of multicellular organisms. Stem cells raise a number of fundamental questions regarding lineage restriction and cellular differentiation, and they hold enormous promise for cell‐based therapies. Here I propose a theoretical framework for stem cell biology based on the concepts of autopoiesis (self‐production) and complementarity. I argue that stem cells are pivotal in the self‐production of the organism and that we (...) need complementary approaches to understand their probabilistic behavior. I discuss how this framework generates testable hypotheses regarding stem‐cell functions. BioEssays 26:1013‐1016, 2004. © 2004 Wiley Periodicals, Inc. (shrink)
