Jóvenes y blogs : Construcciones de sentido en torno a la delgadez

La presente investigación indaga los sentidos construidos por jóvenes que producen blogs PRO ANA en castellano, en torno a la delgadez como un estilo de vida a seguir. Desde los estudios de comunicación/cultura, y a partir de una perspectiva y un análisis socioculturales, se realiza un recorrido por diferentes blogs en donde se encuentran modos de comunicarse: ayunos, credos, la determinación de mandamientos y la firma de contratos, entre otras estrategias analizadas para sostener el estilo de vida. Así mismo, se problematiza a partir de le exploración a quién/es están explícitamente dirigidas estas plataformas identitarias. Enmarcados en las condiciones sociales e históricas del mundo que transitan, los jóvenes son foco de discursos que estigmatizan sus prácticas cotidianas. Sus decisiones son puestas en cuestión cuando desean alcanzar la delgadez a través de restringir su alimentación y, a su vez, darlo a conocer en el espacio virtual. La intención de este estudio no fue la de formular una definición, sino comprender procesos de significación y producción de sentido desde una dimensión cultural que dé cuenta de la vida social de jóvenes ubicados material y simbólicamente en el espacio social actual. En la investigación se realiza, además, un posicionamiento conceptual sobre la juventud, el consumo y la relación que se establece entre jóvenes, consumo y cuerpos delgados, así como un recorrido por las investigaciones que han servido de insumo para la problematización de la tesis

PWM Control of a Buck Converter with an Amorphous Core Coil

Pulse-width modulation is widely used to control electronic converters. One of the most topologies used for high DC voltage/low DC voltage conversion is the Buck converter. It is obtained as a second order system with a LC filter between the switching subsystem and the load. The use of a coil with an amorphous magnetic material core instead of air core lets design converters with smaller size. If high switching frequencies are used for obtaining high quality voltage output, the value of the auto inductance L is reduced throughout the time. Then, robust controllers are needed if the accuracy of the converter response must not be affected by auto inductance and load variations. This paper presents a robust controller for a Buck converter based on a state space feedback control system combined with an additional virtual space variable which minimizes the effects of the inductance and load variations when a not-toohigh switching frequency is applied. The system exhibits a null steady-state average error response for the entire range of parameter variations. Simulation results are presented.

La dimensión sonora del paisaje. Herramientas, modelos y prototipos aplicados para la interpretación del paisaje sonoro pretérito

Arrancando en la definición de paisaje como construcción de un espacio virtual desde una posición referencial, la investigación constituye una inmersión en la escucha como mirada específica para llevarlo a cabo. La investigación se centra en la búsqueda de una serie de estrategias: herramientas de interpretación y modelos de análisis de la realidad que pueden interactuar con el medio espacial. Mediante el estudio del territorio a través de parámetros vinculados a las energías dinámicas existentes en el mismo, el fin es aportar una nueva lectura, una transcripción del evento sonoro generador del ser de un lugar, empleando para ello el lenguaje arquitectónico y la notación espacio-temporal. El acantilado del Pointe du Hoc se toma como primer caso de estudio para el planteamiento del análisis de la dimensión sonora del territorio, a través de la fabricación de ntermediarios espaciales, que constituirán un modelo aplicable a otros lugares cuya identidad y energía sonora formen un rasgo significativo de su existencia. PALABRAS CLAVE Paisaje sonoro, sonido, Intermediario espacial, territorio Starting in the definition of landscape as building a virtual space from a reference position, this research is an immersion in listening as specific look to carry it out. The research is focused on a number of strategies: prototypes, tools for interpretation and analysis models of reality that can interact with the space environment. By studying the area using parameters linked to existing dynamic energies in territory, the aim is to provide a new reading, a transcript of the sound event generator, employing the architectural language and space-temporary notation. The Pointe du Hoc cliff is taken as a first case study for the approach to the analysis of the sound dimension of the territory, through space intermediaries, which will be a model for other places whose sound energy is the significance of their existence.

A CONCEPÇÃO SOBRE SER HUMANO PARA O DISCENTE DO CURSO DE ADMINISTRAÇÃO: APROXIMAÇÕES COM A FENOMENOLOGIA DE EDITH STEIN

As grandes Revoluções que a história oficial relata apresentam um aspecto comum: a evolução do processo de comunicação aliada à evolução tecnológica. A partir do Século XX, as informações passaram a circular em número e em velocidade escalares. A interdependência e a interligação dos países, nações e pessoas estreitaram-se, pois a mobilidade no espaço virtual, progressivamente, relativiza as distâncias e os espaços geofísicos. Todavia, a avalanche de conhecimento, de aprimoramento científico e de desenvolvimento econômico parece não ser suficiente para responder, concretamente, as questões que ainda assolam a humanidade. Neste cenário, o presente trabalho tem por objetivo aproximar a concepção de ser humano para discentes do curso de administração com as categorias existenciais presentes no pensamento de Edith Stein, por meio dos objetivos específicos: Compreender o que é ser humano para o discente do curso de administração em uma IES Confessional do ABC Paulista; descrever o que é ser humano a partir do pensamento fenomenológico de Edith Stein; buscar convergências, divergências e/ou idiossincrasias entre os relatos de discentes do curso de administração em uma IES Confessional do ABC Paulista e o pensamento de Edith Stein. Para tal, foram colhidos cinco relatos de discentes de administração, por meio dos quais foram feitas aproximações, convergências-divergências com as categorias analíticas da concepção de ser humano no pensamento de Edith Stein para cada sujeito, tendo como questão norteadora: o que é ser humano para você ? Após a coleta, as entrevistas foram analisadas tendo como referência os trabalhos de Edith Stein (fenomenologia eidética), Castro (2003), Flauzino (2012) e Estanislau (2010), cumprindo as seguintes etapas: literalização dos relatos ingênuos, levantamento das unidades de sentido, levantamento e análise fenomenológica das categorias, as quais possibilitaram o diálogo intersubjetivo e objetivo com os pressupostos teóricos sobre o tema em pauta. Categorias estas denominadas de: 1. Corpo Físico e Corpo Vivente; 2. Espírito; Sujeito Psicofísico; 3. Comunidade. A partir da análise das categorias, observou-se que a concepção de ser humano conflui para a unidade do ser, ser este que é composto por corpo vivente, psique e espírito, de forma a possibilitar relações com o outro e com o ambiente. Não é possível ser humano sem um encontro com o outro, sem o respeito mútuo, sem a liberdade de ser o que se é. Emerge a dos relatos a dimensão comunitária, somente na qual se é possível realizar a humanidade, por meio de atos de liberdade, respeito e de compaixão. Desvelou-se também dentro destes relatos, que quando se é humano, a vida em seu todo é realizada de forma harmoniosa. Poder-se-á, então, por meio do revelar-se do fenômeno, obter uma nova forma de olhar, de pensar e questionar as práticas vivenciadas na Administração, contribuindo com a formação de uma massa crítica para as ciências sociais aplicadas da administração, ao refletir sobre o que há de mais estruturante e nuclear no discente de administração.

A construção identitária em um fórum de discussão: um estudo com alunos da EAD

The aim of this study is to highlight the cultural identities of Spanish undergraduate students from Instituto Federal de Educação, Ciência e Tecnologia – IFRN, in integration with Universidade Aberta do Brasil – UAB, in the distance modality, built from utterances produced by them in a forum discussion online. For this, we chose to analyze the thematic forum “Using fragments of the internet is an ethical act?” generated in the first semester of 2011, linked to the Reading and Writing course. The interest of this researcher to highlight the cultural identities of these subjects, in the Virtual Learning Environment, emerged from the contact with this reality, in which it was found that the statements constructed by students were rich in positions, meanings and interactions. By producing their speeches, such subjects nurture a reflection on how we can establish meaning in the interaction created in online teaching as well as on the construction of cultural identities of the subject within that virtual space. The way students participate in the discussion forum represents learning experiences that lead to the construction of cultural identities, which determine the trajectory of the subjects, which makes the identity an ongoing process. Our theoretical reference follows the interdisciplinary approach of Applied Linguistics and is based on the socio-historical model of language, with language construed as a social practice. This study also established an interface with cultural studies, as it uses the concept of cultural identity in postmodernity. Analysis of the utterances lead to plurality, with a multiplicity of identities, as evidenced from the positioning of the subjects, some focused on the agreement, others on the disagreement, or even on the boldness. It was found also in the investigative path that these identities can be constructed and reconstructed if they are immersed in another set of historically determined social practices.

Estratégias de trabalho com blogs no ensino de geometria em turmas de 5° ano do ensino fundamental

This paper presents a survey conducted through collaborative work, which took place in a suburb school in the city of Uberlandia-MG. The research is characterized as case study and has a qualitative approach. Had the objective to look for different strategies of teaching and learning through the use of technology in pedagogical practice. Regarding the methodology in this research, we analyzed the work with the support of blogs, whose pages were used for student records and discussions directed to the geometry content. The students who were attending the fifth (5th) year of elementary school were invited to participate in this project. However, the research subjects were only those students who accepted the invitation to participate in the study through statement signed by parents. The project was developed with 30 students in the second half of 2014 and another 30 in the first half of 2015. The physical space at school, where most of the project activities were done was at the computer lab. In the process of compiling the data, at school, the following instruments were used: field notes produced by the entire project team, photographs and footage of the activities produced in the computer lab and in classroom (recorded by the research team) questionnaires, interviews, virtual space records: the blogs. The results of this research mainly focused on the analysis of the fifth year student‟s productions records in blogs. Regarding the conclusion, the research has shown that blogs, software and differentiated dynamic studies attracted the student‟s attention, leaving them mostly instigated by the unknown. Gradually, students built their own knowledge from their mistakes and successes. The entire work process enabled the computer lab to be an environment that is used not just to solving computerized and tedious drills. The blogs production work in groups, developed in students the reading and writing of both the mother language as symbols and mathematical nomenclature. The interaction between students became noticeable throughout the project, since it provided the student‟s personal growth, respect, tolerance and mutual cooperation. In this sense, we concluded that the project greatly contributed to the students' literacy process in the mother language, mathematics and computer literacy.

Exploring Intrinsic Gender Identity Using Second Life

Virtual Worlds (VWs) provide an environment to understand and explore notions of gender and identity, particularly given the ability for users to experiment with gender in online worlds. Our study analyses gender identity using the virtual space of Second Life (SL) to explore experiences and responses to gender in an avatar. We introduced 46 novice users to the VW of SL in order to see if real life gender influenced their choices of avatar. Participants selected the gender of their original avatar and once they were used to SL, they were then asked to change the gender of that avatar. We used mixed methods research consisting of paper based questionnaires (n=34) and focus groups (n=46) conducted in SL. Nearly all participants chose an initial avatar that reflected their real-life gender with females (n=22) reporting higher levels of identification with this initial avatar. Females were significantly more concerned with the gender-specific appearance of their initial avatar. On swapping gender, females reported higher levels of discomfort and many changed back before 7 minutes. Males (n=24) did not report significant discomfort with their changed-gender avatar and did not revert back to their original avatar as quickly. Our findings suggest that female participants in this study tended to reinforce gender binaries through such things as clothing, hairstyles and behaviors of their avatars. Male participants were less likely to experience discomfort through changing the gender of their avatar (with the males noting they still perceived an avatar with a female appearance as male).

Extending body space in immersive virtual reality: a very long arm illusion

Recent studies have shown that a fake body part can be incorporated into human body representation through synchronous multisensory stimulation on the fake and corresponding real body part- the most famous example being the Rubber Hand Illusion. However, the extent to which gross asymmetries in the fake body can be assimilated remains unknown. Participants experienced, through a head-tracked stereo head-mounted display a virtual body coincident with their real body. There were 5 conditions in a between-groups experiment, with 10 participants per condition. In all conditions there was visuo-motor congruence between the real and virtual dominant arm. In an Incongruent condition (I), where the virtual arm length was equal to the real length, there was visuo-tactile incongruence. In four Congruent conditions there was visuo-tactile congruence, but the virtual arm lengths were either equal to (C1), double (C2), triple (C3) or quadruple (C4) the real ones. Questionnaire scores and defensive withdrawal movements in response to a threat showed that the overall level of ownership was high in both C1 and I, and there was no significant difference between these conditions. Additionally, participants experienced ownership over the virtual arm up to three times the length of the real one, and less strongly at four times the length. The illusion did decline, however, with the length of the virtual arm. In the C2-C4 conditions although a measure of proprioceptive drift positively correlated with virtual arm length, there was no correlation between the drift and ownership of the virtual arm, suggesting different underlying mechanisms between ownership and drift. Overall, these findings extend and enrich previous results that multisensory and sensorimotor information can reconstruct our perception of the body shape, size and symmetry even when this is not consistent with normal body proportions.
