A matemática no ciberespaço: um olhar fenomenológico para a expressão dos sujeitos

With the implementation of new technologies on the world stage of communication, Internet access has become increasingly numerous. Being sought by this means all kinds of information, from knowledge to entertainment. This paper intends to report the experience in two communities of the Internet, particularly in the social network Orkut, entitled I Hate Mathematics and I Love Mathematics, whose members are students, teachers and people who want to express how they feel about mathematics. The goal is to understand what took the members of these communities to hate or love Mathematics, clarifying the nature of the network Orkut and its contribution to mathematics education. For the analysis of data from field work, we use the phenomenological approach. The procedures followed by such approach allowed us to build four open categories: Research and Background, revealing that the research activities allow students to develop strategies, develop creativity and shows that what is learned in classroom is not just an accumulation of knowledge; Teacher's Role shows that it is necessary that the teacher understands the meaning of being a teacher and worry about being a student; Acquisition Technique, it is necessary that students be able to understand what is done and how it is done, and Sense of What is Done, to do is not directly linked to comprehend. The interpretation of these categories helped us understand the investigated giving us source to analyze how Information and Communication Technologies (ICT) can help the teacher understand the student's relationship with Mathematics

Comunicação Organizacional e Mídias Sociais: o uso das redes sociais nas estratégias de comunicação

The growing concern of experts in organizational communication with appropriate business relationships with its various stakeholders through digital platforms causes an upgrowth on the number of studies on the topic of social media.

The objective of this monograph is to make an exploratory study that relates to organizational communication and social media, and discuss how the theories can contribute to the optimization of communication mediated by specific platforms that bring with them opportunities for interaction and relationship in the digital environment

O citar no Twitter: o caso de Clarice Lispector

The phenomenon of the World Wide Web, the Internet, has revolutionized the way we live in a contemporary relevance. The relationships among people have changed since the media also changed: the cyberspace has been established as an important vehicle of communication in which different languages, cultures and peoples coexist. Within the virtual space there are several fica possibilities for communication, interaction, fun, knowledge etc. Everything happens extremely quickly. An interesting example of that are blogs that, to survive virtuality, require constant updating. It has become interesting to notice the factor of personal expressiveness taking a new shape in the context of network, before being seen in elements such as diaries, poetry, artistic production or debate. The chances and, thus, the need to find people to interact and to share interests has taken a gigantic proportion, and, in this way, sources of audiovisual and reading activities are always in vogue, being shared every second. Blogging can be about different subjects, but what is perceived on all blogs is the strong trace of written text is always presented. Twitter has established itself as a microblogging network for the expression of dynamism, information sharing and interaction. Thus, it was interesting to approach the manner language is expressed in these microblogs thinking about the way that literary discourse is constructed when is seen, on quotations, in the context of this social network: Twitter. Being able to attest the great increase on the occurrences of quotes from different literary genres, it was useful to pay attention to this fact. In Brazil, Twitter has thousands of users, fans and readers, that rewrite and quote authors. The number of quotations is so abundant that it has popularized several Brazilian writers, such as: Clarice Lispector and Caio Fernando Abreu; authors that are frequetenly quoted. So, we made usage of semiotic studies of the French line. In...

Burning Graphene Layer-by-Layer

Graphene, in single layer or multi-layer forms, holds great promise for future electronics and high-temperature applications. Resistance to oxidation, an important property for high-temperature applications, has not yet been extensively investigated. Controlled thinning of multi-layer graphene (MLG), e.g., by plasma or laser processing is another challenge, since the existing methods produce non-uniform thinning or introduce undesirable defects in the basal plane. We report here that heating to extremely high temperatures (exceeding 2000 K) and controllable layer-by-layer burning (thinning) can be achieved by low-power laser processing of suspended high-quality MLG in air in "cold-wall" reactor configuration. In contrast, localized laser heating of supported samples results in non-uniform graphene burning at much higher rates. Fully atomistic molecular dynamics simulations were also performed to reveal details of oxidation mechanisms leading to uniform layer-by-layer graphene gasification. The extraordinary resistance of MLG to oxidation paves the way to novel high-temperature applications as continuum light source or scaffolding material.

Infância e imagem: concepções sobre imagens de crianças no Facebook

In this course conclusion work intends to initially trace a brief history of childhood, watching as their design has been changing over time until you get to today, then it will be contextualized childhood and his relationship with the image, ie as this is narrated from images and phrases linked to them shared daily on a social network of communication accessed around the world, Facebook. Seek to identify the way that these images have in childhood now, in view of the existence of a Aesthetics domination over people, in the philosophical sense of the word means that which affects the senses, so the images can be produced Aesthetic emotions: ways of being, acting and feeling. For this will be a collection of materials on this web site, and to give theoretical support to work a literature will also be held, using for the basement of research, the theories of thinkers Walter Benjamin, Foucault, Philippe Aries, René Schérer

A configuração de forças na constituição histórica do trabalho como estratégia de cuidado em saúde mental: problematizações foucaultianas

Investigated in this paper, as contributions to Foucault's genealogy of knowledge, the historical constitution of the joint activities between Work and Care in Mental Health (called Therapeutic Workshops, among other names) in their different purposes and dimensions that contributed to the production care of patients with psychological distress at different times. History is here understood as a multiplicity (and nonlinearity) of time series and various blending and shuffleforming speeches as truths. In conjunction we have discussed, we conclude that the work as a therapeutic modality in nursing homes, there emerged in the world of psychiatry, but of capitalism. Associated with measures of occupation "empty minds" of misfits, later earned the position of an instrument of discipline and social regulation. With the Psychiatric Reform, activities Work in Mental Health have been re-invented as spaces enablers of access to citizenship and contractuality social network users.

Redes sociais na Internet: uma investigação sobre práticas de compartilhamento de arquivos no Facebook

The social networking sites have experienced a large and rapid growth in recent years and bring together millions of users in Brazil and worldwide. Such networks allow adding groups of people with common interests or relationships, enabling members of this group to communicate and exchange information. Some social networks have specific goals, for example, aggregate individuals with common interests and professional relationships. However, they all share information in some way, whether in the form of short texts, photos, videos, among others. Sharing information in files is also a growing activity on the Internet and can be done in various ways, from sending files via email to multiple contacts to make available areas shared by the same contacts. However, applications are not yet available to enable file sharing on Facebook, considered the premier social network today. Given the growing demand for sharing files over the Internet, and a large number of users familiar with the use of these integrated applications for Facebook there is a demand for applications that allow users to share files with their contacts in this social network. This study aims to investigate how users use Facebook, and their practices for file sharing. It is believed that the results will substantiate future projects to develop software for file sharing on Facebook. Due to the exploratory nature of this research, the choice was made for a survey to collect data, applied through the web. From the results obtained, was possible to observe a frequent use of file sharing, but no interest in paid services. Regarding Facebook, was possible to observe their extensive use in both the frequency of access as the hours spent, as well as an increased use of applications (games, quiz, etc.). The full set of results shows a favorable environment for developing applications for sharing files on Facebook.

Instâncias de consagração na cibercultura: um estudo sobre a atuação do internauta no MySpace

With new technologies, there are fields of unprecedented artistic legitimation and consecration. On the Internet, MySpace is used as a social network whose peculiarity lies in the interactivity of between artists (established and independent) users and non-artists. The website has revealed new names in the music scene from the popularity they gained by its peers. To see how the communication happens within that environment, was chosen the band profile Restart, whose audience is the majority of MySpace teen (youth 12 to 17 years). The analysis of this article is part of a broader research and the results already obtained allow us to see, within the limits of the selected area, that the Internet not only introduces a new field of action, but new instances of artistic consecration.

Inclusão e cidadania digital no Brasil: a (des) articulação das políticas públicas

The incipient but quickly expansion action on the Information and Communications Technologies (ICT) in Africa it is now just having different impact on these societies. One of these relates bear on how users are identified with these tools. Just like that we find individuals identify as bloggers, twitter followers or cyber activist. This contribution analyzes the Senegal’s fact where a successful use of social nets and web 2.0 tools experience (at least in repercussion) as social and political involvement while presidential elections in 2012 is tied to come back an identity: Cyber activist. Senegalese circumstance shows us how this identity has a personal and assertiveness dimension as well collective aspects of belonging to a community. One as much as the other, show us personal traits in contrast to previous beliefs, basically because it fuse and confuse virtual and reality. Due to dynamics from expanding technology, this identity is youthful and urban, but not only. This situation creates new dynamics at least in this affected group. For this reason, besides knowing emergence and evolution of this fact, it raises some of the involvement in social and political involvement from groups traditionally “invisible”. Beyond the new social behavior there are new changes in the rules of the game in order to start new social revolution.

This paper discusses the possibility of receiver’s participation in the production of television content mediated by online social networks. Buoyed by media convergence, this research demonstrates how the receiver has been working in online digital media such as TV can take advantage of the specific interaction between the medias to promote the creation of collaborative content, in which the user of social network may interfere the result of the product developed, becoming a new mediatic protagonist. Tool not so used for the production of television that slowly begins to enter the virtual reality, the forging of this new compose process would not only entertain the receiver, but also enrich the language and content television constantly criticized. This study shows the influence of the television medium in which is discussed online, the attitude still shy of the user in content production, and discusses the potential of social networks as a channel of communication between producers and receivers. This work is structured from the definition of social network, in addition to conducting the study what kind of interaction between TV and online social networks is practiced today. Finally, debate whether the potential interaction between TV and social networks is used to its fullest.
