El debate de la medición digital: Una piedra en el camino para la consolidación de la inversión publicitaria

La llegada de ingresos provenientes de la distribución digital de la prensa continúa siendo reducida. A pesar de su volumen de lectores, el aumento de posibilidades dentro de los formatos publicitarios, la capacidad de medición del retorno de la inversión que ofrece el medio digital y la aparente unificación en la medición de audiencia que desde 2012 está presente en el mercado. De esta manera, los diferentes medios continúan sin conseguir rentabilizar la migración digital que cada día conlleva continuos gastos sin ofrecer beneficios. La audiencia como moneda de cambio en la comercialización de espacios publicitarios ha perdido todo su valor, pese al retorno de la inversión que ofrece. Este trabajo describe esta problemática y los cambios realizados antes y después del «fin del debate de la medición de audiencias» con el objetivo de poner en valor la venta de los espacios publicitarios digitales. En concreto se analiza el caso de los diarios digitales por su elevada lectura y sus escasos ingresos.

Transgresión de las identidades tradicionales de género mediante la representación gráfica de mujeres protagonistas para videojuegos desarrollada por niños y niñas

El artículo identifica y analiza el discurso predominante que poseen 12 niños y 7 niñas de 7° y 8° año básico pertenecientes a 4 establecimientos educacionales en la ciudad de Talca en Chile, en torno a la transgresión de las identidades tradicionales de la mujer en los videojuegos. Para ello durante el 1° semestre del año 2014 al interior de un programa de formación de profesores/as en Artes Visuales se implementa una estrategia didáctica centrada en la expresión gráfica denominada “Crea tu propia personaje para videojuego”. Haciendo partícipes a niños y niñas junto a profesionales en formación de una propuesta metodológica basada en la Investigación-Acción enmarcada en las prácticas profesionales. Concluyendo tras el análisis semántico de dibujos y relatos, que las imágenes representativas de la mujer en los videojuegos transgreden las identidades tradicionales de género al interior de un marco androcéntrico predominante.

Redefinición de las TIC en el museo: del discurso invasivo al inclusivo

Las TIC son inseparables de la museografía in situ e imprescindibles en la museografía en red fija y móvil. En demasiados casos se han instalado prótesis tecnológicas para barnizar de modernidad el espacio cultural, olvidando que la tecnología debe estar al servicio de los contenidos de manera que resulte invisible y perfectamente imbricada con la museografía tradicional. Las interfaces móviles pueden fusionar museo in situ y en red y acompañar a las personas más allá del espacio físico. Esa fusión debe partir de una base de datos narrativa y abierta a obras materiales e inmateriales de otros museos de manera que no se trasladen las limitaciones del museo físico al virtual. En el museo in situ tienen sentido las instalaciones hipermedia inmersivas que faciliten experiencias culturales innovadoras. La interactividad (relaciones virtuales) debe convivir con la interacción (relaciones físicas y personales) y estar al servicio de todas las personas, partiendo de que todas, todos tenemos limitaciones. Trabajar interdisciplinarmente ayuda a comprender mejor el museo para ponerlo al servicio de las personas.

Tech Fashion : Fashion Institutionalization in Digital Technology

This thesis explores aesthetization in general and fashion in particular in digital technology design and how we can design digital technology to account for the extended influences of fashion. The thesis applies a combination of methods to explore the new design space at the intersection of fashion and technology. First, it contributes to theoretical understandings of aesthetization and fashion institutionalization that influence digital technology design. We show that there is an unstable aesthetization in mobile design and the increased aesthetization is closely related to the fashion industry. Fashion emerged through shared institutional activities, which are usually in the form of action nets in the design of digital devices. “Tech Fashion” is proposed to interpret such dynamic action nets of institutional arrangements that make digital technology fashionable and desirable. Second, through associative design research, we have designed and developed two prototypes that account for institutionalized fashion values, such as the concept “outfit-centric accessory.” We call for a more extensive collaboration between fashion design and interaction design.

Learning at the Interstices; Locating Practical Philosophies for Understanding Physical/virtual Inter-spaces

Virtual worlds are relatively recent developments, and so it is tempting to believe that they need to be understood through newly developed theories and philosophies. However, humans have long thought about the nature of reality and what it means to be “real.” This paper examines the three persistent philosophical concepts of Metaxis, Liminality and Space that have evolved across more than 2000 years of meditation, contemplation and reflection. Our particular focus here is on the nature of the interface between the virtual and the physical: at the interstices, and how the nature of transactions and transitions across those interfaces may impact upon learning. This may, at first, appear to be an esoteric pursuit, but we ground our arguments in primary and secondary data from research studies in higher education.

“Digital Diagnostics and Communication (DDC) system” Redesigning the Emergency Ambulance

During the development of a new treatment space for the UK emergency ambulance participatory observations with front-line clinicians revealed the need for an integrated patient monitoring, communication and navigation system. The research identified the different information touch-points and requirements through modes of use analysis, day-in-the-life study and simulation workshops with clinicians. Emergency scenario and role-play with paramedics identified 5 distinct ambulance modes of use. Information flow diagrams were created and checked by paramedics and digital User Interface (UI) wireframes were developed and evaluated by clinicians during clinical evaluations. Feedback from clinicians defined UI design specification further leading to a final design proposal. This research was a further development from the 2007 EPSRC funded “Smart Pods” project. The resulting interactive prototype was co-designed in collaboration with ambulance crews and provides a vision of what could be achieved by integrating well-proven IT technologies and protocols into a package relevant in the emergency medicine field. The system has been reviewed by over 40 ambulance crews and is part of a newly co-designed ambulance treatment space.

Monitoring sandy shores morphologies by DGPS: a practical tool to generate digital elevation models

The highly dynamic nature of some sandy shores with continuous morphological changes require the development of efficient and accurate methodological strategies for coastal hazard assessment and morphodynamic characterisation. During the past decades, the general methodological approach for the establishment of coastal monitoring programmes was based on photogrammetry or classical geodetic techniques. With the advent of new geodetic techniques, space-based and airborne-based, new methodologies were introduced in coastal monitoring programmes. This paper describes the development of a monitoring prototype that is based on the use of global positioning system (GPS). The prototype has a GPS multiantenna mounted on a fast surveying platform, a land vehicle appropriate for driving in the sand (four-wheel quad). This system was conceived to perform a network of shore profiles in sandy shores stretches (subaerial beach) that extend for several kilometres from which high-precision digital elevation models can be generated. An analysis of the accuracy and precision of some differential GPS kinematic methodologies is presented. The development of an adequate survey methodology is the first step in morphodynamic shore characterisation or in coastal hazard assessment. The sample method and the computational interpolation procedures are important steps for producing reliable three-dimensional surface maps that are real as possible. The quality of several interpolation methods used to generate grids was tested in areas where there were data gaps. The results obtained allow us to conclude that with the developed survey methodology, it is possible to Survey sandy shores stretches, under spatial scales of kilometers, with a vertical accuracy of greater than 0.10 m in the final digital elevation models.

Parental mediation, YouTube’s networked public, and the baby-iPad encounter: mobilizing digital dexterity.

This study collected a sample of YouTube videos in which parents recorded their young children utilizing mobile touchscreen devices. Focusing on the more frequently viewed and highly-discussed videos, the paper analyzes the ways in which babies’ ‘digital dexterity’ is coded and understood in terms of contested notions of ‘naturalness’, and how the display of these capabilities is produced for a networked public. This reading of the ‘baby-iPad encounter’ helps expand existing scholarly concepts such as parental mediation and technology domestication. Recruiting several theoretical frameworks, the paper seeks to go beyond concerns of mobile devices and immobile children by analyzing children’s digital dexterity not just as a kind of mobility, but also as a set of reciprocal mobilizations that work across domestic, virtual and publically networked spaces.

Objeto e ambiente virtual de aprendizagem: análise de conceito na perspectiva evolucionária de Rodgers

Introdução: No contexto dos avanços tecnológicos incorporados ao ensino, os objetos e os ambientes virtuais de aprendizagem constituem ferramentas de apoio ao ensino colaborativo e interativo cada vez mais desenvolvidas (Aguiar, 2011; Alencar, 2012). A fim de nortear o desenvolvimento e validação destes relevantes instrumentos educacionais, verifica-se a necessidade de conhecer os conceitos que nortearam o seu desenvolvimento e identificar suas origens e aplicações, o que pode favorecer a uniformização do uso e significado pelos pesquisadores nas diversas áreas do conhecimento. Objetivos: Analisar o conceito de objeto e de ambiente virtual de aprendizagem na perspetiva evolucionária de Rodgers. Metodologia: Estudo descritivo, de abordagem mista, realizado a partir das etapas propostas por Rodgers (2000) em seu modelo de análise conceitual. A coleta de dados ocorreu em agosto de 2015 com a busca de dissertações e teses no Banco de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), Brasil. Os dados quantitativos foram analisados a partir de estatística descritiva simples e os conceitos através de análise lexicográfica com suporte do software Interface de R pour Analyses Multidimensionnelles de Textes et de Questionneires (IRAMUTEQ). Resultados: A amostra é constituída por 161 estudos, onde predominaram os decorrentes de mestrado acadêmico (67,1%). O conceito "ambiente virtual de aprendizagem" (AVA) foi apresentado em 99 (61,5%) estudos, enquanto "objeto virtual de aprendizagem" (OVA) em apenas 15 (9,3%). Em relação aos atributos dos conceitos, destacaram-se o incentivo à participação, colaboração e interação de discentes (77; 47,8%) e a integração de diversas mídias nos processos de ensino e aprendizagem (74; 46,0%). Quanto aos antecedentes, o mais citado foi a popularização da internet (52; 32,3%). Como consequentes, destacam-se a exigência de uma aprendizagem colaborativa (30; 18,6%) e a necessidade de incorporação de tecnologias à luz de abordagens pedagógicas (28; 17,4%). O conceito AVA teve 12 termos substitutos, com destaque para ambiente virtual de ensino e aprendizagem (12; 7,5%). Já o termo OVA apresentou 5 substitutos, com predomínio de Objeto de Aprendizagem (11; 6,8%). Enquanto conceito relacionado, destacou-se Educação à Distância, discutido em todos os trabalhos analisados. Conclusões: Ambiente virtual de aprendizagem foi compreendido enquanto um sistema computacional que integra funcionalidades e ferramentas que possibilitam a construção de um processo de ensino aprendizagem interativo, online, acessado por navegadores na internet ou em redes locais. Em contrapartida, objeto virtual de aprendizagem foi conceituado enquanto um recurso digital de tamanho limitado que pode ser reutilizado dentro de várias atividades e estratégias pedagógicas. Em síntese, pode-se afirmar que um ambiente virtual de aprendizagem reúne vários e diferentes tipos de objetos virtuais de aprendizagem em um contexto pedagógico comum.

The virtual class as a knowledge democratization model

This paper presents the conceptualization and use of a virtual classroom in the course EIF-200 Fundamentos de Informática, first course in the Information Systems Engineering career of the Universidad Nacional of Costa Rica. The virtual classroom is seen as a complement to the class and is conceived as a space that allows to centralize teaching resources, thereby promoting the  democratization of knowledge among students and teachers. Furthermore, this concept of virtual classroom helps to reduce the culture of individualism, present many times in university teaching practices, and contributes to create new opportunities to learn from other colleagues within a culture of reflection, analysis and respectful dialogue aimed to improve the teaching practices.

SPACE-DEPLOYED, THIN-WALLED ENCLOSURE FOR A CRYOGENICALLY-COOLED HIGH TEMPERATURE SUPERCONDUCTING COIL

The interaction of magnetic fields generated by large superconducting coils has multiple applications in space, including actuation of spacecraft or spacecraft components, wireless power transfer, and shielding of spacecraft from radiation and high energy particles. These applications require coils with major diameters as large as 20 meters and a thermal management system to maintain the superconducting material of the coil below its critical temperature. Since a rigid thermal management system, such as a heat pipe, is unsuitable for compact stowage inside a 5 meter payload fairing, a thin-walled thermal enclosure is proposed. A 1.85 meter diameter test article consisting of a bladder layer for containing chilled nitrogen vapor, a restraint layer, and multilayer insulation was tested in a custom toroidal vacuum chamber. The material properties found during laboratory testing are used to predict the performance of the test article in low Earth orbit. Deployment motion of the same test article was measured using a motion capture system and the results are used to predict the deployment in space. A 20 meter major diameter and coil current of 6.7 MA is selected as a point design case. This design point represents a single coil in a high energy particle shielding system. Sizing of the thermal and structural components of the enclosure is completed. The thermal and deployment performance is predicted.
