Na trilha juvenil da mídia: dos suplementos teens para as tecnologias digitais

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.

Metodologia para avaliação do nível de usabilidade de bibliotecas digitais: um estudo na Biblioteca Virtual de Saúde

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.

Projeto colaborativo em ambientes digitais de atividades de aprendizagem e avaliação para aquisição de competências em informação e documentação

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.

Avaliação de uma técnica para geração de modelos digitais de superfície utilizando múltiplas imagens

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.

Descrição de recursos imagéticos digitais: apresentação de um modelo conceitual

Techniques of image capture have advanced along with the technologies of information and communication and unthinkable numbers of information available and imagery are stored in digital environments. The objective of this study is point out difficulties found in the construction of imagetic representations of digital resources using the instruments available for the treatment of descriptive information. The results we have the mapping of descriptive elements to digital images derived from analyzing of the schemes to guide the construction of descriptive records (AACR2R, ISBD, Graphic Materials, RDA, CDWA, CCO) and the conceptual model FRBRer. The result of this analysis conducted the conceptual model, Functional Requirements for Digital Imagetic Data RFDID to the development of more efficient ways to represent the use of imagery in order to make it available, accessible and recoverable from the data persistence descriptive, flexibility, consistency and integrity as essential requirements for the representation of the digital image.

Recomendações de usabilidade e de acessibilidade em projetos de ambientes informacionais digitais para idosos

The usability and accessibility, when applied to digital information environments, provide ease of use and access to information, respectively. Thus, we aim to discuss these concepts and apply them in specific digital environments to the elderly through the documentary and bibliographic study of specific recommendations on projects for elderly users. This study was conducted in conjunction with students at the Universidade Aberta à Terceira Idade (UNATI) - UNESP - Marilia, who assisted in the classification of recommendations for usability and accessibility are essential (Priority 1), important (Priority 2) and optional (Priority 3). The results indicate the importance of this type of study for the digital and social inclusion of older people by facilitating elements of access and use of information, providing the building more inclusive informational architectures. The resulting recommendations can be used as a starting point for the design of digital environments for the elderly in a specific heuristic evaluation, for example. However, it remains important to the application of usability testing with users, including the application to validate these recommendations, since different contexts may arise from the implementation of different elements, resources and information services.

Bibliotecas escolares e instrumentos digitais nos espaços escolares: uma pesquisa em Marília-SP

The article reports on research conducted with fifteen teachers and forty-five students in three high schools municipal Marília - SP, with the goal of mapping relationships between school libraries, computer labs and digital devices. The investigation is linked to the other two poles: one in the Faculty of Education, Federal University of Uberlândia and another at the French Institute of Education, in Lyon, France. Responses were obtained through questions previously formulated and recorded by scholars in an interview situation. The article initially retrieves historical projects of French in the late nineteenth century with the intention of establishing linkages with the situation in 2012, in Brazil. It then presents and comments on the graphics with data. The findings indicate the absence of organicity in relations between libraries and computer labs. Handheld devices outside of school are predominantly used to play and participate in social networking sites.

Representação e Persistência para acesso a Recursos Informacionais Digitais gerados dinamicamente em sítios oficiais do Governo Federal

The Information Access law, sanctioned in November 18, 2011, regulates the constitutional right of access to public information by Brazilian citizens. Although this law requires the provision of information of public interest, it does not define how such information should be made available. Ideally, information should be in an open format, allowing its use in an efficient and fast way. In the official sites of the federal government the way information is currently available does not allow its reuse as they are presented in dynamic pages from the selection parameters and filters. The objective aim of this paper is to present the system called MDDIR Tool, which proposes ways to persist, represent and retrieve digital information resources generated by the Federal Government official sites. Although this system had been designed for a specific purpose, it may be applied to other fields with similar characteristics. The purpose is to facilitate the access to open data, allowing such data to be consolidated and organized , generating new knowledge and information easy to be interpreted by the general population.

Representação iterativa e folksonomia assistida para repositórios digitais

Information retrieval has been much discussed within Information Science lately. The search for quality information compatible with the users needs became the object of constant research.Using the Internet as a source of dissemination of knowledge has suggested new models of information storage, such as digital repositories, which have been used in academic research as the main form of autoarchiving and disseminating information, but with an information structure that suggests better descriptions of resources and hence better retrieval.Thus the objective is to improve the process of information retrieval, presenting a proposal for a structural model in the context of the semantic web, addressing the use of web 2.0 and web 3.0 in digital repositories, enabling semantic retrieval of information through building a data layer called Iterative Representation.The present study is characterized as descriptive and analytical, based on document analysis, divided into two parts: the first, characterized by direct observation of non-participatory tools that implement digital repositories, as well as digital repositories already instantiated, and the second with scanning feature, which suggests an innovative model for repositories, with the use of structures of knowledge representation and user participation in building a vocabulary domain. The model suggested and proposed ─ Iterative Representation ─ will allow to tailor the digital repositories using Folksonomy and also controlled vocabulary of the field in order to generate a data layer iterative, which allows feedback information, and semantic retrieval of information, through the structural model designed for repositories. The suggested model resulted in the formulation of the thesis that through Iterative Representation it is possible to establish a process of semantic retrieval of information in digital repositories.

Integração do framework manakin com a plataforma dspace para múltiplas apresentações visuais de informações nos repositórios digitais

Digital repositories are currently being used by education and research institutions in Brazil as an alternative for propagating scientific and academic results, mainly to reach institutional memory and visibility. However, the way these results are presented may influence their use, affecting user-system interaction through the interface components. Thus, it is possible to state that an unique digital information environment can offer different ways of visual presentation, customizing informational and visual components for specific users communities. In this context, tools are being developed as a resource to make access and use of information easier, and to increase the usability of digital informational environments. One of these tools, Manakin, is presented in this paper, as well as its integration with the DSpace platform, in order to enable multiple visual presentations, stressing the importance of the differentiation and direction of interfaces by a single repository to the various knowledge fields. So, results and examples of repositories with multiple visual presentations are introduced, to facilitate the use of the presented tool, as well as to reinforce the importance of a differentiated visual identity by areas of knowledge in a single repository, by means of literary and exploratory analysis.

Encontrabilidade da Informação: atributos e recomendações para ambientes informacionais digitais

At first, this paper presents the epistemological and theoretical bases that support the inclusion of an operational concept for the findability of information in the field of Information Science. In a second moment, it defines the key attributes and recommendations for the findability of information, with a view to their understanding in a practical perspective, from the epistemological and theoretical support presented. From a theoretical, exploratory, bibliographic and documentary study, the results reveal that epistemologically the findability of information fits in Information Science in post-custodial paradigm that focuses on access to information and is significantly influenced by Information and Communication Technologies. The theoretical conclusions of this concept focus on the evolution of the Web and from the perspective of the dimensions of language, where there is as pragmatic trend, as technological development that combines the actions taken by informational and institutional individuals in digital information environments. Given that these actions turn enable or not the findability of information, these individuals can be understood as mediators. Therefore, the concept of infocommunicational mediation is the basis for the findability of information. For its application in digital information environments, were defined attributes and guidelines which should be considered in the context of Information Architecture. The attributes characterizing the concept and guidelines point at practical actions for the design and for evaluation of the findability of information. Epistemological, theoretical and practical concepts addressed underpin the called operative concept in information science and should be further explored in this scientific field.
