Development of a Collaborative Platform for Art Education: From Pedagogy to Technology

We report on the development of a Java-based application devised to support collaborative learning of Art concepts and ideas over the Internet. Starting from an examination of the pedagogy of both Art education and collaborative learning we propose principles which are useful for the design and construction of a “lightweight” software application which supports interactive Art learning in groups. This application makes “dynamics” of an art work explicit, and supports group interaction with simple messaging and “chat” facilities. This application may be used to facilitate learning and teaching of Art, but also as a research tool to investigate the learning of Art and also the development and dynamics of collaborating groups. Evaluation of a pilot study of the use of our system with a group of 20 school children is presented.

Applications of a Collaborative Open Object Oriented Learning Environment to Electronics, Computing and Mathematics Education

A lightweight Java application suite has been developed and deployed allowing collaborative learning between students and tutors at remote locations. Students can engage in group activities online and also collaborate with tutors. A generic Java framework has been developed and applied to electronics, computing and mathematics education. The applications are respectively: (a) a digital circuit simulator, which allows students to collaborate in building simple or complex electronic circuits; (b) a Java programming environment where the paradigm is behavioural-based robotics, and (c) a differential equation solver useful in modelling of any complex and nonlinear dynamic system. Each student sees a common shared window on which may be added text or graphical objects and which can then be shared online. A built-in chat room supports collaborative dialogue. Students can work either in collaborative groups or else in teams as directed by the tutor. This paper summarises the technical architecture of the system as well as the pedagogical implications of the suite. A report of student evaluation is also presented distilled from use over a period of twelve months. We intend this suite to facilitate learning between groups at one or many institutions and to facilitate international collaboration. We also intend to use the suite as a tool to research the establishment and behaviour of collaborative learning groups. We shall make our software freely available to interested researchers.

Conhecimento, sociabilidade e lazer em jogos online : uma etnografia na "Lan House do Paulo" em São Gonçalo do Amarante-RN

In a highly dynamic society such as we live, have access to the virtual world is an increasingly common practice, is aiming to study, work or to search leisure through chat rooms, sites and games, being incorporated by the most varied groups that end up appropriating these new possibilities of interaction, shaping them in order to adapt them to their needs / wants. The specific purposes pursued through the use of tools available over the Internet can vary considerably when one takes into account specific user groups, which makes the topic quite relevant to problematization, especially when we take into account access through lan houses. This research seeks to study the networks of knowledge, sociability and leisure formed by young people who frequented the "Lan house do Paulo" in São Gonçalo do Amarante - RN based on the use of the online role-playing-game World of Warcraft, which makes possible the interaction of several users through an avatar resident in a virtual world, theoretically questioning the importance of this type of platform for the development and maintenance of social interactions among its users

Consumo del internet de los estudiantes del Colegio Herlinda Toral

El uso de Internet aparece estrechamente vinculado con la posibilidad de comunicarse a través de un soporte digital. Las tecnologías digitales permiten una gran velocidad de comunicación. Este medio acorta las distancias, uno puede conectarse a nivel de todo el mundo y a toda hora, sin embargo crea enlaces de amistad con muchas personas de diferente sexo, edad, sin lugar a duda lo que los jóvenes buscan a través de estos canales. Los programas de entretenimiento están marcando el ritmo de vida cotidiana en los jóvenes que lo utilizan, porque se ven prestos a utilizar constantemente las redes sociales y orienta a las personas en general a consumir este medio, ya que al indagar se encuentran con otras personas que en ese momento se encuentran en línea, o al no estar comunicados se dejan mensajes que exigen una respuesta. Internet nos ofrece numerosas alternativas en comparación con otros medios: se accede a través de líneas de conexión, módems con cable, acceso fijo sin cable. Son sistemas alimentados con banda ancha en telecomunicaciones a la transmisión de datos la cual se envía información, se incrementa la velocidad de transmisión efectiva, que permite que Internet llegue a todos los hogares

Developmental Neural Correlates of Social Interaction

Children develop in a sea of reciprocal social interaction, but their brain development is predominately studied in non-interactive contexts (e.g., viewing photographs of faces). This dissertation investigated how the developing brain supports social interaction. Specifically, novel paradigms were used to target two facets of social experience—social communication and social motivation—across three studies in children and adults. In Study 1, adults listened to short vignettes—which contained no social information—that they believed to be either prerecorded or presented over an audio-feed by a live social partner. Simply believing that speech was from a live social partner increased activation in the brain’s mentalizing network—a network involved in thinking about others’ thoughts. Study 2 extended this paradigm to middle childhood, a time of increasing social competence and social network complexity, as well as structural and functional social brain development. Results showed that, as in adults, regions of the mentalizing network were engaged by live speech. Taken together, these findings indicate that the mentalizing network may support the processing of interactive communicative cues across development. Given this established importance of social-interactive context, Study 3 examined children’s social motivation when they believed they were engaged in a computer-based chat with a peer. Children initiated interaction via sharing information about their likes and hobbies and received responses from the peer. Compared to a non-social control, in which children chatted with a computer, peer interaction increased activation in mentalizing regions and reward circuitry. Further, within mentalizing regions, responsivity to the peer increased with age. Thus, across all three studies, social cognitive regions associated with mentalizing supported real-time social interaction. In contrast, the specific social context appeared to influence both reward circuitry involvement and age-related changes in neural activity. Future studies should continue to examine how the brain supports interaction across varied real-world social contexts. In addition to illuminating typical development, understanding the neural bases of interaction will offer insight into social disabilities such as autism, where social difficulties are often most acute in interactive situations. Ultimately, to best capture human experience, social neuroscience ought to be embedded in the social world.

Este trabajo hace un estudio de algunas de las herramientas de seguridad disponibles en .Net Framework así como la forma de usarlas en un desarrollo web bajo la metodología de desarrollo de ASP.NET siguiendo el modelo Vista-Controlador y usando como entorno de desarrollo Visual Studio. Además de repasar las herramientas disponibles y la forma de uso se ha desarrollado también una aplicación de ejemplo: ItemCoteca-Web; en la que se demuestra cómo resolver el registro de usuarios, la autenticación y autorización de forma segura. En paralelo se ha implementado un cliente Android: Itemcoteca-app que realiza autenticación, registro y dispone de un chat seguro de incidencias para hablar con administradores OnlineEste trabajo no solo presenta las APIs disponibles sino también las buenas prácticas que define Microsoft para el uso de sus herramientas. En particular nos centramos en los tres tipos de controladores que podemos encontrar en una aplicación web Asp.net que son Controllers, WebApi y SignalR, comentando sus diferencias y su uso para clientes Web y móviles.

Cybersex in portuguese chatrooms: A study of sexual behaviors related to online sex

The present article is about a particular form of sexual activity on the Internet: cybersex in chatrooms-in Portuguese by Portuguese people. This study aims to identify the reasons for engaging in cybersex on chats and the behavioral domains that characterize this activity. To carry out the study, we developed a self-report questionnaire that we made available on a website. The sample was collected online (n = 400) through the Portuguese Internet Relay Chat. Factor analyses revealed seven domain structures: (a) social skills, (b) preference for cybersex, (c) filter for a later date, (d) sex by phone, (e) fantasies, (f) using masks, and (g) impact on real relationships. We found a huge variety of sexual attitudes and behaviors connected to cybersex in chatrooms and the existence of two major trends: (a) people that use these chats as a starting place for offline relationships (online anonymity prevents the fear of rejection and social sanctions in real life), and (b) people who want and prefer online sex without any interest in further real contacts.

L'hepcidine : un possible lien entre l'inflammation chronique et le métabolisme du fer dans les maladies rénales chroniques félines

Le rôle de l'inflammation dans le développement et la progression des maladies rénales chroniques (MRC) chez le chat a été peu étudié. L'hepcidine est une protéine de la phase aigue (PPA) de l'inflammation qui contribue au développement des anémies lors de MRC chez l'homme. Les objectifs de cette étude sont de comparer les concentrations en PPAs, en erythropoietine (EPO) ainsi que le statut en fer entre un groupe de chats sains et en MRC. 18 chats sains et 38 chats en MRC ont été recrutés de façon prospective. Les examens réalisés incluaient hématologie, biochimie, analyse d'urine, Serum amyloid A (SAA), haptoglobine (HAP), EPO, hepcidine,fer, TIBC et ferritinne. Nous avons observé une augmentation significative des concentrations en SAA et en hepcidine ainsi qu'une diminution significative du fer et du TIBC dans le groupe MRC (P < .05). Une corrélation positive entre la créatinine et certaines PPAs (SAA and hepcidin; P < .05) était présente. L'augmentation de SAA et hepcidine était significativement associé avec une diminution du TIBC et de l'hématocrite dans le groupe MRC. Les 14 (37%) chats anémiques du groupe MRC avaient une concentration significativement plus basse en fer et en TIBC (P < .05), changements compatibles avec une déficience fonctionelle en fer. Aucun chat n'avait un panel de fer compatible avec une carence en fer absolue. En conclusion, les résultats de cette étude suggèrent que les MRC chez le chat sont des conditions pro-inflammatoires, ayant un impact sur le métabolisme du fer.

"You have ruined this entire experiment…shall we stop talking now?" Orientations to the experimental setting as an interactional resource

One limitation widely noted in sociolinguistics is the tension presented by the ‘observer’s paradox’ (Labov, 1972), i.e. the notion that everyday language is ‘susceptible to contamination by observation’ (Stubbs, 1983: 224). The observer’s paradox has been perceived to present significant challenges to traditional sociolinguistic researchers seeking to explore the processes at work during ordinary interaction. More recently, scholars have begun to argue that in fact the presence of a recording device, rather than being a mere constraint on spoken interaction, is in itself an interactional resource explicitly oriented to by participants (Speer & Hutchby 2003; Gordon 2012). Drawing on a collection of transcripts collected in experimental conditions as part of a wider project exploring the relationship between language and identity, this paper seeks to explore how these orientations manifest themselves in the context of Instant Messaging (IM) conversations. We show different orientations to the experimental setting, and different understandings of the role of the researcher – represented in this case by the IM chat archive – as both a topic of discussion and as a participant themselves.

La gestion facultaire en contexte budgétaire difficile : analyse sous l’angle de l’activité des doyens

Cette thèse examine le comportement de quatre doyens canadiens dont les facultés sont en situation financière précaire. Dans un contexte d’imputabilité accrue des établissements universitaires et de modification constante aux rapports de pouvoir internes, cette étude présente une importance particulière pour la compréhension de l’exercice réel des fonctions administratives des cadres académiques intermédiaires. La recherche scientifique sur ce sujet attribue aux doyens une contribution vitale au bon fonctionnement des établissements; le doyen en demeure pourtant un des rouages les moins étudiés. La position intermédiaire qu’occupent les doyens les place dans un conflit de rôle évident. Pris entre des rôles et des attentes contradictoires émis par la communauté facultaire, d’une part, et par la direction de l’établissement, d’autre part, ils doivent conjuguer cette ambiguïté avec des responsabilités croissantes en matière de gestion financière, de leadership et d’opérationnalisation des visées stratégiques de l’université. Comprendre la façon dont les doyens arrivent à mobiliser les leviers institutionnels à leur disposition pour résoudre des situations critiques permettra d’améliorer notre compréhension de la complexité de la prise de décision au niveau intermédiaire et notre compréhension globale du fonctionnement des établissements universitaires. La présente étude importe de la théorie culturelle-historique de l’activité (culturalhistorical activity theory, ou CHAT) un modèle d’analyse de l’activité collective en situation de contradictions systémiques. Quatre doyens d’une même université ont été interviewés afin de présenter une situation vécue de difficulté budgétaire, et le processus de résolution qui a suivi. Les données ont été analysées qualitativement afin de décrire les interventions que réalisent les doyens sur les leviers présents dans leurs environnements. Les résultats suggèrent que les participants ont misé sur une maîtrise fine des rouages institutionnels et sur des interventions diversifiées afin de résoudre les contradictions de leurs systèmes d’activité.
