Redefining the Academic Library Managing the Migration to Digital Information Services

Academic libraries are faced with a daunting series of challenges brought on by the digital revolution. In an era when millions of books, articles, images, and videos available instantaneously via the web, libraries across all institutional types are experiencing declining demand for their traditional services, built around the storage and dissemination of physical resources. At the same time, new demand for digital information services and collaborative learning spaces promise new areas of opportunity and engagement with patrons. A rapid and orderly transition to “the library of the future” requires difficult trade-offs, however, as no institution can afford to continue expanding both its commitment to comprehensive, local print collections as well as new investments in staff, technology, and renovations. This report illustrates how progressive academic libraries are evolving in response to these challenges, providing case studies and best practices in managing library space, staff, and resources.

A TV digital brasileira a serviço do processo judicial eletrônico: o ambiente da interatividade da TV digital brasileira como proposta para um modelo na gravação de audiência das varas federais criminais

Este trabalho descreve algumas das soluções atualmente adotadas pelos tribunais federais para a gravação de audiência, bem como indica a oportunidade que o ambiente de interatividade da TV Digital Brasileira oferece para uma proposta de modelo de documento eletrônico de escritório que sirva de suporte para o resultado da gravação de audiência (texto, som e imagem), bem como possa contribuir para a mudança de paradigma dos atuais sistemas processuais (softwares). O objetivo é estabelecer um padrão fundamentado em uma política pública (Governo Eletrônico Brasileiro e Sistema Brasileiro de TV Digital Terrestre), onde não existam restrições comerciais quanto ao uso das novas tecnologias de comunicação e informação no que se refere ao mínimo para se privilegiar a inclusão social sem perda de eficiência. O trabalho é formado por dois tipos de conteúdo: parte textual e parte digital. A parte textual contém o resultado de uma pesquisa realizada junto aos tribunais federais, bem como apresenta os principais pontos do Governo Eletrônico Brasileiro e do Sistema Brasileiro de TV Digital Terrestre. Ainda descreve a estrutura montada na elaboração e realização da parte digital. Por sua vez, a parte digital reúne o material utilizado para a apresentação de protótipos (vídeos e exemplos de aplicações), para demonstrar as possibilidades de interatividade da TV Digital Brasileira e dos benefícios que os jurisdicionados e os operadores do Direito alcançariam com a proposta.

O discurso do grotesco na mídia digital

This study presents our research on the discourse of the grotesque in digital media, specifically in two blogs. We rely on the theoretical-conceptual and methodological discourse analysis of the French School. We analyzed a set of posts in the following blogs: Eu Sou Ryca and Cleycianne, and we did it based on some propositions on the discourse of the grotesque by Mikhail Bakhtin (1999a), Muniz Sodré and Raquel Paiva (2002), Wolfgang Kayser (2003) and Mary Russo (2000). The expressions of the grotesque analyzed in the blogs Eu Sou Ryca and Cleycianne result predominantly in humorous effect, obtained by means of irony and parodization, which calls for ridicule and relegation, through a strong tension between the beautiful and the ugly, the socially acceptable and the aberration, the taste for the strange and the aesthetically striking. The grotesque appears initially as a significant feature of ornamental paintings found in Roman caves in the late fifteenth century, and today it can be seen permeating from sculptures, paintings, literary works, talk shows for television, videos hosted in cyberspace, specifically in the collective domain of weblogs. This work seeks to analyze how the discourse of the grotesque constitutes the humorous process in its insertion in cyberspace

Modelagem paramétrica linear aplicada à faixa de sinal de televisão digital para cidades densamente arborizadas

Este trabalho apresenta uma modelagem paramétrica (auto-regressiva) linear aplicável a estudos de propagação de televisão digital e telefonia celular para cidades densamente arborizadas. A modelagem proposta apresenta um forte embasamento estatístico e depende apenas de dados provenientes de medição, no caso dados relativos a potência recebida e o valor de PSNR (Peak Signal-to-Noise Ratio). Um algoritmo genético é utilizado no cálculo dos parâmetros de ajuste do modelo a um conjunto de dados. O trabalho foi realizado na faixa de televisão digital e foram analisadas duas variáveis: a potência recebida do sinal e o valor de PSNR. Foram executadas campanhas de medição na cidade de Belém. Nestas medições foram coletados dados de potência e gravados vídeos da programação diária de uma emissora de televisão. Os resultados podem ser aplicados no planejamento de serviços de telecomunicações.

Cultura da Wikipédia como Política de capacitação compartilhada em meio digital de socialização do conhecimento

Presents a developing laboratory within History of Culture, subject taught in the Library and Archive Studies at UNESP (Marilia). The project is based upon the foundations of research line Information and Technology: students from the second under graduation year participate in the improving of 27 entries in Portuguese language Wikipedia. The aim is to capacitate for scientific reading and writing in digital media, habilitate for the information identification and recuperation and for the interpretation and understanding of formal and contents aspects and its reorganization. It includes activities of search, selection, remix and republishing of texts, images, audio and videos in the convergence of diverse hypertext information sources, supported by tutors with strategic abilities in digital environments. In this sense it was adhered to the international Wikipedia Foundation University Campus Ambassadors project. It’s also aimed to induce sharing and collaboration behaviors with the purpose of creating necessary habits for the informational empowerment in Brazil. As methodology is to optimize the work of individuals already trained in wiki culture and to create in within the subject information sharing programs with a more specialized bias, giving greater credibility to the digital environment. The environment syntaxes helps in the learning of the complementary skills of reading and writing and offers itself as an open repository from which information can be reused. It is, thus, an empowerment strategy in the search of autonomy and self reliance considering intersemiotic knowledge in the edition, visualization and understanding of information in the social web. A second step of a verifying research on the environment’s credibility after the consolidation and dissemination of the entries improvement work is proposed.

Video Quality Assessments on Digital TV and Video Streaming Services Using Objective Metrics

There is a wide range of telecommunications services that transmit voice, video and data through complex transmission networks and in some cases, the service has not an acceptable quality level for the end user. In this sense the study of methods for assessing video quality and voice have a very important role. This paper presents a classification scheme, based on different criteria, of the methods and metrics that are being studied in recent years. This paper presents how the video quality is affected by degradation in the transmission channel in two kinds of services: Digital TV (ISDB-TB) due the fading in the air interface and video streaming service on an IP network due packet loss. For Digital TV tests was set up a scenario where the digital TV transmitter is connected to an RF channel emulator, where are inserted different fading models and at the end, the videos are saved in a mobile device. The tests of streaming video were performed in an isolated scenario of IP network, which are scheduled several network conditions, resulting in different qualities of video reception. The video quality assessment is performed using objective assessment methods: PSNR, SSIM and VQM. The results show how the losses in the transmission channel affects the quality of end-user experience on both services studied.

Tecnología cloud para el hogar digital

El mundo tecnológico está cambiando hacia la optimización en la gestión de recursos gracias a la poderosa influencia de tecnologías como la virtualización y la computación en la nube (Cloud Computing). En esta memoria se realiza un acercamiento a las mismas, desde las causas que las motivaron hasta sus últimas tendencias, pasando por la identificación de sus principales características, ventajas e inconvenientes. Por otro lado, el Hogar Digital es ya una realidad para la mayoría de los seres humanos. En él se dispone de acceso a múltiples tipos de redes de telecomunicaciones (3G, 4G, WI-FI, ADSL…) con más o menos capacidad pero que permiten conexiones a internet desde cualquier parte, en todo momento, y con prácticamente cualquier dispositivo (ordenadores personales, smartphones, tabletas, televisores…). Esto es aprovechado por las empresas para ofrecer todo tipo de servicios. Algunos de estos servicios están basados en el cloud computing sobre todo ofreciendo almacenamiento en la nube a aquellos dispositivos con capacidad reducida, como son los smarthphones y las tabletas. Ese espacio de almacenamiento normalmente está en los servidores bajo el control de grandes compañías. Guardar documentos, videos, fotos privadas sin tener la certeza de que estos no son consultados por alguien sin consentimiento, puede despertar en el usuario cierto recelo. Para estos usuarios que desean control sobre su intimidad, se ofrece la posibilidad de que sea el propio usuario el que monte sus propios servidores y su propio servicio cloud para compartir su información privada sólo con sus familiares y amigos o con cualquiera al que le dé permiso. Durante el proyecto se han comparado diversas soluciones, la mayoría de código abierto y de libre distribución, que permiten desplegar como mínimo un servicio de almacenamiento accesible a través de Internet. Algunas de ellas lo complementan con servicios de streaming tanto de música como de videos, compartición y sincronización de documentos entre múltiples dispositivos, calendarios, copias de respaldo (backups), virtualización de escritorios, versionado de ficheros, chats, etc. El proyecto finaliza con una demostración de cómo utilizar dispositivos de un hogar digital interactuando con un servidor Cloud, en el que previamente se ha instalado y configurado una de las soluciones comparadas. Este servidor quedará empaquetado en una máquina virtual para que sea fácilmente transportable e utilizable. ABSTRACT. The technological world is changing towards optimizing resource management thanks to the powerful influence of technologies such as Virtualization and Cloud Computing. This document presents a closer approach to them, from the causes that have motivated to their last trends, as well as showing their main features, advantages and disadvantages. In addition, the Digital Home is a reality for most humans. It provides access to multiple types of telecommunication networks (3G, 4G, WI-FI, ADSL...) with more or less capacity, allowing Internet connections from anywhere, at any time, and with virtually any device (computer personal smartphones, tablets, televisions...).This is used by companies to provide all kinds of services. Some of these services offer storage on the cloud to devices with limited capacity, such as smartphones and tablets. That is normally storage space on servers under the control of important companies. Saving private documents, videos, photos, without being sure that they are not viewed by anyone without consent, can wake up suspicions in some users. For those users who want control over their privacy, it offers the possibility that it is the user himself to mount his own server and its own cloud service to share private information only with family and friends or with anyone with consent. During the project I have compared different solutions, most open source and with GNU licenses, for deploying one storage facility accessible via the Internet. Some supplement include streaming services of music , videos or photos, sharing and syncing documents across multiple devices, calendars, backups, desktop virtualization, file versioning, chats... The project ends with a demonstration of how to use our digital home devices interacting with a cloud server where one of the solutions compared is installed and configured. This server will be packaged in a virtual machine to be easily transportable and usable.
