A autora procura discutir as consequências de a cultura juvenil ser hoje o ingrediente fundamental da comunicação digital, e os efeitos desta cultura sobre o comportamento dos jovens e sobre o próprio conceito de juventude. Ela enfatiza que nas últimas décadas tal conceito passou definir, mais do que uma faixa etária, uma espécie de mercadoria, oferecida, para qualquer interessado, na mídia, em academias de ginástica, casas de shows, shopping centers e nos mais variados espaços urbanos. A pesquisadora analisa o comportamento de várias gerações de jovens, especialmente depois da Segunda Guerra Mundial, a partir da consolidação da TV e de mídias voltadas especificamente para esse público, como os suplementos teen. E mostra que as novas tecnologias digitais - com sua portabilidade, mobilidade e interatividade - estão trazendo novos cenários, novas conformações da vida social, múltiplas configurações de tempo e desenhando espaços antes inimagináveis, ocupados principalmente pelos jovens. Trata-se de uma geração extremamente conectada e rebelde à sua maneira contra os valores tradicionais, que está desenvolvendo um novo estilo e um novo modo de entender o processo comunicativo, com grande dinamismo. No entanto, trata-se também de uma geração que não consegue fugir do aspecto mais perverso das tecnologias digitais, pois estas, ao evoluírem e se transformarem praticamente a cada dia e quase sempre a reboque do mercado, exigem seguidas adaptações, que os jovens nem sempre conseguem acompanhar de forma rápida e sistemática, de modo a ficarem imunes a frustrações.

The aim of this paper was to discuss aspects of applying a methodology to evaluate usability in digital libraries. A methodology that deals with the systematization of a usability assessment tool for digital libraries was used. The aim was to investigate the level of usability of the Virtual Health Library, applying a method that measures effectiveness, efficiency and users' satisfaction when using the digital library. Methodologically, it is characterized as a formal test of usability. This test consisted of a list of ten tasks to be performed while using the website of the Virtual Health Library and the Likert scale was used to assess users' satisfaction. A quantitative approach based on descriptive statistics was adopted to analyze the results. The test was applied between December 5 and December 21, 2011, at the computer lab of the Health Sciences Center of the Universidade Federal da Paraíba. The results of the usability test enabled us to measure the level of usability of the Virtual Health Library, which is considered to provide a high level of usability.

The search for international impact and the need to create formal or informal networks of academic cooperation are some of the most common features of the current training offered by many universities. Aware of this difficulty and the desirability of creating synergies to enrich teaching and academic collaboration networks between universities, an experience is presented, in the context of the teaching of Information and Documentation, of inter-university collaboration for the joint design of learning activities and skills assessment, developed by teachers in the public universities of Zaragoza and Salamanca (Spain) and the São Paulo Universidade Estadual Paulista Júlio de Mesquita Filho (São Paulo, Brazil). The experience is developed using models that facilitate the structuring of learning activities aimed at the acquisition of common skills. Each activity that is proposed and developed is recorded in a spreadsheet which collects the information arranged in various fields such as: description, skills, objectives, expected learning outcomes, tools, required resources and materials, evaluation criteria, amongst others, so that the student can see what he is asked to do, how to do it and how useful it will be. This way of designing skills-based learning activities is possible, in geographically diverse academic settings through the use of Information Technology and Communication, enabling both remote cooperation between teachers and also materials offered on the platforms of each of the universities.

This study investigated Social Care as an institution that creates mechanisms for the production of subjectivity in the care of children and adolescents. For this, we used some analytical coordinates, both conjectural and structural, models of care for mapping care in confrontation in the field of Social Care. It was concluded that there was two contradictory paradigms, in the dialectical sense, organizing social care, one being the philanthropic mode and the other the socioeducative mode. The first, which is hegemonic in the field, corresponds to a care entity still organized from philanthropic care and is guided by a minority age logic, articulated by a discourse of criminalizing the lower classes. It is informally based on the legal concept of irregular situations, which would develop preventive, repressive, correctional and moralizing care practices. The construction of a socioeducative mode implies socioeducative care that aims for an effective increase in the rights of children and adolescents, based on their status as subjects and citizens, through democratic, dialogic, participatory, multi-disciplinary and fundamentally emancipatory institutional practices.

The efficient generation of digital surface model (DSM) from optical images has been explored for many years and the results are dependent on the project characteristics (image resolution, size of overlap between images, among others), of the image matching techniques and the computer capabilities for the image processing. The points generated from image matching have a direct impact on the quality of the DSM and, consequently, influence the need for the costly step of edition. This work aims at assessing experimentally a technique for DSM generation by matching of multiple images (two or more) simultaneously using the vertical line locus method (VLL). The experiments were performed with six images of the urban area of Presidente Prudente/SP, with a ground sample distance (GSD) of approximately 7cm. DSMs of a small area with homogeneous texture, repetitive pattern, moving objects including shadows and trees were generated to assess the quality of the developed procedure. This obtained DSM was compared to cloud points acquired by LASER (Light Amplification by Simulated Emission of Radiation) scanning as wells as with a DSM generated by Leica Photogrammetric Suite (LPS) software. The accomplished results showed that the MDS generated by the implemented technique has a geometric quality compatible with the reference models.
