Hacia la aldea virtual : evolución de las tecnologías comunicativas y de los modelos antropológicos

Estudiar los medios de comunicación significa estudiar al hombre, la sociedad en la que vive, su evolución y las perspectivas de desarrollo futuro. Después de haber puntualizado brevemente los avances tecnológicos salientes en la historia del hombre y de haber identificado las características más relevantes de las diversas redefiniciones antropológicas que siguieron a la introducción de algunos nuevos medios, nos detendremos principalmente en el estudio de las peculiaridades de los instrumentos de comunicación de masa más modernos, de la fotografía al cine, de la televisión a Internet. El objetivo principal de este aporte, lejos de querer proveer sistemas teóricos definitivos, es trazar un conjunto coherente de temáticas capaces de suscitar nuevas y proficuas cuestiones y de promover un debate abierto a los más diversos aportes, con particular atención a los avances de las comunicaciones telemáticas.

Rhiz'hommes: redes de subjetividades

Com a profusão de imagens fotográficas do mundo capitalista e o incentivo para que todos sejamos produtores, o modo de fruição das fotografias e a nossa relação com esses simulacros vão se alterando. A necessidade que a web traz de nos apresentarmos em imagens faz com que tenhamos que fabricá-las e através delas passamos a nos relacionar de maneira narcísica. Com o projeto artístico Rhiz'hommes vão se discutindo as construções desses avatares nos sites de relacionamento e a (des)construção da figura masculina heteronormativa como observadora ideal, ponto de fuga para onde deveriam convergir todas as representações. Junto à queda do homem cartesiano, a autoria e a originalidade artística foram se transformando e cedendo espaço a práticas mais permissivas e abrangentes. Essa diluição de fronteiras é o epíteto de tempos pós-orgânicos de relações telemáticas e rizomas de subjetividades

Educação e Cibercultura: narrativas de mobilidade ubíqua

A cibercultura, cultura contemporânea mediada pelo digital em rede, potencializada pelos usos dos dispositivos móveis, delineia novas formas de relações: econômicas, sociais, profissionais, políticas, educacionais, trazendo novos contornos à sociedade. Neste contexto, esta dissertação buscou compreender em que medida, a mobilidade dada pelas redes telemáticas sem fio podem ser utilizadas dentro de um contexto educativo, entendendo que esse contexto se dá dentrofora da universidade, nos diversos espaçostempos da cidade. Buscamos, para tanto, articular à pesquisa-formação (Macedo, Santos e Josso) com abordagem multirreferencial (Ardoino), os pressupostos das pesquisas nos dos com os cotidianos (Alves) e criamos, no contexto formativo da disciplina de Didática, da Licenciatura de Pedagogia da Universidade do Estado do Rio de Janeiro, atos de currículo com os usos dos dispositivos móveis e do digital em rede, em diálogo com os estudos da cibercultura (Lévy, Lemos, Santaella, Santos). Analisando os usos do digital em rede e dos dispositivos móveis no contexto formativo dos estudantes de Didática e suas narrativas, chegamos aos seguintes achados: a) as interfaces sociais definem a percepção do espaço em que estamos assim como as possibilidades de interação comunicacional com os outros; b) a mobilidade dada pelo digital em rede e pelos usos dos dispositivos móveis imprime outras dinâmicas ao como e quando aprenderensinar; c) expandir as estratégias de aprendizagemensino disponíveis por meio do digital em rede aumenta a possibilidade de acesso a conteúdos, informações, reconfigurando o papel da universidade; d) no que tange ao acesso livre à rede, tanto dentro da universidade quanto na cidade, há necessidade de políticas públicas efetivas para a inclusão digital; e) no âmbito da pesquisa-formação, nossa pesquisa contribuiu para a formação de docentes, criando as ambiências pedagógicas necessárias para o desenvolvimento de habilidades e competências para uma gestão mais flexível do conhecimento e dos processos de aprendizagemensino dentrofora da universidade.

Prospects of integration of aquaculture with animal husbandry and land crop culture in Tripura State

Tripura is a densely populated small state with meagre water resources. 47.51% of the population is constituted by socio-economically backward, illiterate, orthodox, tribal and scheduled castes. Some of them are nomad and a majority of the rest of the population is refugees from Bangladesh, but almost 100% is fish eater. Settlement of tribes in villages, provision of nutritious food and employment therefore calls for proper utilization of every resource they have. The State is poor in water resources but recently has created 21,636.23 ha of new water area. Tripura is rich in pig population, besides poultry birds. Paddy is the main crop cultivated in arable lands. An integration of livestock raising and land based agriculture with pisciculture practices around mini barrages will help in solving the problems to a great extent. The paper is an attempt to outline the prospects of integration of aquaculture with animal husbandry and land based crop culture in Tripura State.

The Ocean Colour Climate Change Initiative: III. A round-robin comparison on in-water bio-optical algorithms

Satellite-derived remote-sensing reflectance (Rrs) can be used for mapping biogeochemically relevant variables, such as the chlorophyll concentration and the Inherent Optical Properties (IOPs) of the water, at global scale for use in climate-change studies. Prior to generating such products, suitable algorithms have to be selected that are appropriate for the purpose. Algorithm selection needs to account for both qualitative and quantitative requirements. In this paper we develop an objective methodology designed to rank the quantitative performance of a suite of bio-optical models. The objective classification is applied using the NASA bio-Optical Marine Algorithm Dataset (NOMAD). Using in situRrs as input to the models, the performance of eleven semi-analytical models, as well as five empirical chlorophyll algorithms and an empirical diffuse attenuation coefficient algorithm, is ranked for spectrally-resolved IOPs, chlorophyll concentration and the diffuse attenuation coefficient at 489 nm. The sensitivity of the objective classification and the uncertainty in the ranking are tested using a Monte-Carlo approach (bootstrapping). Results indicate that the performance of the semi-analytical models varies depending on the product and wavelength of interest. For chlorophyll retrieval, empirical algorithms perform better than semi-analytical models, in general. The performance of these empirical models reflects either their immunity to scale errors or instrument noise in Rrs data, or simply that the data used for model parameterisation were not independent of NOMAD. Nonetheless, uncertainty in the classification suggests that the performance of some semi-analytical algorithms at retrieving chlorophyll is comparable with the empirical algorithms. For phytoplankton absorption at 443 nm, some semi-analytical models also perform with similar accuracy to an empirical model. We discuss the potential biases, limitations and uncertainty in the approach, as well as additional qualitative considerations for algorithm selection for climate-change studies. Our classification has the potential to be routinely implemented, such that the performance of emerging algorithms can be compared with existing algorithms as they become available. In the long-term, such an approach will further aid algorithm development for ocean-colour studies.

Social Networks Usage Profile: Descriptive study with students in the University of Murcia

Telematic tools are very important for our lives in the present era and moreover this idea is made more evident if we analyse young people behaviours. However, it seems that the possibilities that these tools allow subjects from a professional point of view, beyond the purely playful aspects, are still not fully exploited both by subjects, neither by educational institutions where they learn. Our work studies the uses of social media in the context of university students. In order to this we have designed a research based on quantitative methodology with a survey. We have applied a questionnaire to students in the University of Murcia. The questionnaire was answered by 487 students in the first half of 2014. The survey results confirm our hypothesis that social networks are part of the basic and habitual tools of communication between the youth of our university and eminently used for leisure purposes, and that the tools used for more academic activities are those allowing greater control of privacy.

Visualising Invisible Networks as Collaborative Arts Practice

This paper examines approaches to the visualisation of ‘invisible’ communications networks. It situates network visualisation as a critical design exercise, and explores how community artists might use such a practice to develop telematic art projects – works that use communications networks as their medium. The paper’s hypotheses are grounded in the Australian community media arts field, but could be applied to other collaborative contexts.

History of several mistakes: on differences between Lev Gumilev and Eurasians

This article challenges prevalent views about Gumilev’s relation to classic Eurasianism. On the basis of previously unavailable correspondence and interviews, it is argued that Lev Gumilev had substantial degree of affinity with the original Eurasian movement understood as a scholarly tradition. This was manifested both in his personal contacts with some of its key members, and in his scholarly work on the nomad history, which remained Eurasian in its spirit. However, the most significant departure from Eurasianism, under-appreciated by most scholars, was his theory of ethnogenesis, which attempted to establish a new naturalistic paradigm for study of history.

Experiencia práctica de bases de datos educativas en el campo de la parasitología.

En la presente comunicación se describe la creación y aplicación de una base de datos educativa en el campo de la parasitología, en la Facultad de Biología de la Universidad Complutense de Madrid. El material depositado en las colecciones de parasitología del departamento de zoología y antropología física de la UCM fue fotografiado en su totalidad y con las imágenes resultantes se creó una base de datos (banco de imágenes). El aprovechamiento de estas imágenes, como recurso educativo, se aplicó en tres vertientes: 1. la creación de un museo virtual que será asequible desde Internet; 2. la edición de materiales docentes en el marco de los proyectos de innovación y mejora de la calidad docente de la UCM y 3. el desarrollo de una asignatura telemática, impartida exclusivamente a través de un campus virtual.

Big and little Meccano

The emergence of the mechanical bond during the past 25 years is giving chemistry a fillip in more ways than one. While its arrival on the scene is already impacting materials science and molecular nanotechnology, it is providing a new lease of life to chemical synthesis where mechanical bond formation Occurs as a consequence of the all-important templation Orchestrated by molecular recognition and self-assembly. The way in which covalent bond formation activates noncovalent bonding interactions, switching on molecular recognition that leads to self-assembly, and the template-directed synthesis of mechanically interlocked molecules-of which the so-called catenanes and rotaxanes may be regarded as the prototypes-has introduced a level of integration into chemical synthesis that has not previously been attained jointly at the supramolecular and molecular levels. The challenge now is to carry this I vel of integration during molecular synthesis beyond relatively small molecules into the realms of precisely functionalized extended molecular Structures and superstructures that perform functions in a collective manner as the key sources of instruction, activation, and performance in multi-component integrated Circuits and devices. These forays into organic chemistry by a scientific nomad are traced through thick and thin from the Athens of the North to the Windy City by Lake Michigan with interludes on the edge of the Canadian Shield beside Lake Ontario, in the Socialist Republic of South Yorkshire, on the Plains of Cheshire beside the Wirral, in the Midlands in the Heartland of Albion, and in the City of Angels beside the Peaceful Sea.

Parallel editing, multi-positionality and maximalism: cosmopolitan effects as explored in some art works by Melanie Jackson and Vivienne Dick

Garfield produces a critique of neo-minimalist art practice by demonstrating how the artist Melanie Jackson’s Some things you are not allowed to send around the world (2003 and 2006) and the experimental film-maker Vivienne Dick’s Liberty’s booty (1980) – neither of which can be said to be about feeling ‘at home’ in the world, be it as a resident or as a nomad – examine global humanity through multi-positionality, excess and contingency, and thereby begin to articulate a new cosmopolitan relationship with the local – or, rather, with many different localities – in one and the same maximalist sweep of the work. ‘Maximalism’ in Garfield’s coinage signifies an excessive overloading (through editing, collage, and the sheer density of the range of the material) that enables the viewer to insert themselves into the narrative of the work. In the art of both Jackson and Dick Garfield detects a refusal to know or to judge the world; instead, there is an attempt to incorporate the complexities of its full range into the singular vision of the work, challenging the viewer to identify what is at stake.
