Navegantes e surfistas: as curvaturas do ciberespaço nas vizinhanças dos portais / Sailors and surfers

Marco Antônio Macedo Gutierrez 29 March 2007 (has links)
De um território livre, construído em torno dos princípios da liberdade e da colaboração um ambiente onde pode ser exercida a liberdade de ser (ou parecer), de dizer (ou escrever) e de ouvir (ou ler), para o bem ou para o mal, a massificação do uso da Internet tem constituído um espaço social (virtual) contraditório e diversificado, onde forças cuja vocação parece ser homogeneizar (e possivelmente pasteurizar) esse território livre da diferença têm sido postas em cena. Dentre essas forças, lugar especial é ocupado pelo que se convencionou chamar portais de interesse geral. Tais sites, ao procurar responder a diferentes interesses, de modo a assegurar que o máximo possível de anseios de seus usuários seja satisfeito sem a necessidade de navegarem para fora dos seus domínios, são construídos como empreendimentos cujo sucesso requer o controle do comportamento de navegação dos usuários o que, neste caso, não pode ser feito senão através do discurso (persuasivo). A hipótese que salta aos olhos é evidente: e se este não for apenas um controle pelo discurso, mas um controle do discurso? A premissa é, evidentemente, que tais sites constituem uma categoria especial de artefatos de linguagem produzidos no interior de eventos comunicativos bem determinados, isto é, um gênero emergente do discurso. Assim, o objetivo primário da presente pesquisa consistiu em determinar como o modo de funcionamento discursivo do portal contribui para afetar os hábitos de navegação dos seus usuários, curvando e distorcendo o ciberespaço nas suas vizinhanças. Para isso procuramos abordar o que chamamos atratores retóricos, isto é, aquelas estratégias (discursivas) destinadas a seduzir, convencer ou mesmo fraudar os usuários de modo a assegurar sua permanência na órbita dos portais, fazendo desses websites vetores da ordem do discurso, um elemento de controle do caos típico do ciberespaço, um agente de exorcismo da diferença e subjugação do discurso desenfreado. / The starting point for this reasearch is a free-space built around principles of freedom and cooperation, an environment where may be exerted freedom of being (or pretend), of saying (or writting) and of listening (or reading). The massive growth in use of Internet has built, for better or worse, a social (virtual) contradictorial and varied space. Here certain strenghths have been at work, whoose purpose seems to be homogenise (or possibly pasteurise) a land-free-of-difference. Among these, a special place is occupied by what has been called general interests portals. The latter websites seek to provide answers to several desires. Their aim is to ensure that the most probable wishes of its users are satisfied inside its domains. Thus these websites are built as enterprises, whoose success depends upon the users navigational behavior control. In this particular case this cannot be achieved except by (persuasive) discourse. My research hipothesis might thus have easily seen: what if this is not just a control done through discourse but also a control of discourse? What we assume here is, evidently, that such websites form a special category of language artifacts created inside determined communicative events, e. g., an emerging discoursive genre. Thus the primary objective of the present research was to determine whether the portals discourse functioning mode contributed in altering the navigation habits of its users, bending and distorting cyberspace in its surroundings. Therefore, an effort was made to focus on what have been defined as rhetoric atractors. These are those (discoursive) strategies meant to seduce, convince or even deceive the users in order to assure their permancence in the portals orbit. These strategies, in turn, make the same websites carriers of the order of discourse, an element that controls the typical chaos of the cyberspace, an agent of exorcism of difference and domination of the un restrained discourse

Portal de conhecimento sobre critérios, estratégias, técnicas e ferramentas de teste de aplicações web / Knowledge portal about testing web application criteria, procedures, techniques and tools

Marcella Letícia de Souza Costa 26 February 2008 (has links)
O advento da tecnologia da Internet, juntamente com a World Wide Web, popularizaram e permitiram uma grande expansão e demanda por aplicações web. Por executarem em um ambiete heterogêneo e complexo, as aplicações web apresentam várias características que as diferenciam dos sistemas tradicionais. As particularidades dessas aplicações tornam o fator qualidade essencial para o sucesso dessas aplicações. Alguns requisitos de qualidade, como usabilidade, confiabilidade, interoperabilidade e segurança devem, então, ser validados. Para assegurar a qualidade desejada, são necessárias executar as atividades de Verificação, Validação e Teste (VV&T). Dentre elas, as mais utilizadas são as atividades de teste. Os critérios, estratégias e ferramentas de teste precisam ser identificados e avaliados para se estabelecer uma relação entre os custos e benefícios entre elas, a fim de guiar a escolha de cada uma durante os testes de aplicações web. A realização de estudos experimentais para realizar essa análise beneficia tanto a academia, nas atividades de ensino e pesquisa, como a indústria, nas atividades de seleção e aplicação de critérios, estratégias e ferramentas de teste de aplicações web. Para que os resultados obtidos estejam acessíveis, é proposto o desenvolvimento de um portal de conhecimento que disponibilize de maneira sistemática o conhecimento obtido sobre critérios, estratégias e ferramentas de teste de aplicações web. Esse portal tem como objetivo oferecer às organizações um ambiente compartilhado de conhecimento, a fim de proporcionar a existência de um ciclo de criação, troca, retenção e reuso do conhecimento / The development of internet technology, along with the World Wide Web, made popular and allowed a demand boom and expansion of web applications. Web applications present some characteristics that differentiate them from the traditional systems, since they execute in a heterogeneous and complex environment. The particularities of these applications demand quality as an essential factor for success. Is this way, quality requirements, like usability, reliability, interoperability and security must be validated. To assure the desired quality, it\'s necessary to execute the activities of Verification, Validation and Test (VV&T), where the most used are the testing activities. The testing criteria, strategies and tools need to be identified and evaluated to establish a relation between the costs and benefits, in order to guide the choice of each one during the tests of web applications. The carrying out of experimental studies benefits the academy, in the activities of education and research, and the industry, in the activities of selection and application of criteria, strategies and tools of testing web applications. Moreover, these results need to be accessible to make available information to the interest people. This work presents the development of a knowledge portal, to facilitate knowledge sharing in a systematic way, with information of test criteria, strategies and tools for validating web applications. This portal intends to offer to the organizations and academic institutions a shared environment of web application test knowledge, in order to constitute a knowledge creation, change, retention and reuse cycle

Análise de fatores determinantes do uso de intranets e portais corporativos

Seffrin, Vinícius January 2010 (has links)
O objetivo deste trabalho é contribuir para uma compreensão mais clara sobre o desenvolvimento de intranets e portais corporativos nas organizações, através da análise do principal determinante do sucesso desses projetos: o uso efetivo da tecnologia. Para atingir esse objetivo, esta pesquisa adota uma visão multidimensional, considerando tanto a perspectiva individual como a organizacional. O suporte teórico advém de extensa revisão das pesquisas já publicadas sobre o tema, compreendendo elementos retirados da teoria da estruturação de Giddens e de modelos consagrados de aceitação da tecnologia, como UTAUT e TAM. A metodologia consiste de estudo de caso em três organizações do setor público, com estruturas bastante semelhantes, mas que desenvolveram suas intranets de modo independente. A análise dos contextos organizacionais demonstrou que o uso da tecnologia nos casos estudados, na prática, ainda é muito limitado. Os resultados da pesquisa revelam que esse uso é resultado da conjunção de complexos elementos. Além das deficiências na funcionalidade da tecnologia, os indivíduos não reconheceram a utilidade prática das intranets e, do mesmo modo, não se sentem estimulados a usar a tecnologia. Essa realidade é consequência de problemas na gestão da tecnologia, como a falta de participação efetiva de setores estratégicos, que aliados a aspectos estruturais das organizações, como a divisão entre os setores e a acentuada especialização funcional, contribuem para a manutenção desse quadro. Em sua maioria, esses elementos constituem práticas já institucionalizadas nas organizações, reforçadas pelo comportamento de seus membros no fluir de suas interações. / The goal of this paper is to help provide a clearer understanding of the development of intranets and corporate portals in organizations, by examining the main determinant behind the success of these projects: the effective use of technology. To achieve this goal, this study uses a multidimensional approach, considering both the individual and organizational perspective. The theoretical support is based on an extensive review of already published research on the subject, including elements drawn from Gidden's theory of structuration and renowned technology acceptance models, such as UTAUT and TAM. The methodology consists of a case study in three public sector organizations, with very similar structures, but which developed their intranets independently. The analysis of the organizational contexts demonstrated that the use of technology in the cases studied is still, in practice, very limited. The research findings show that using it is the result of a complex conjunction of elements. Besides the shortcomings in the functionality of the technology, people have not recognized the usefulness of intranets and, likewise, do not feel attracted to use the technology. This reality is a consequence of problems in technology management, such as lack of effective participation of strategic sectors, which combined with structural aspects of organizations, like the division between sectors and accentuated job specialization, contribute toward maintaining this state of affairs. Most of these elements are already institutionalized practices in organizations, reinforced by the behavior of their members in the course of their interactions.

No. of bitstreams: 1 Dissertação - Jorge Luiz Jordão.pdf: 5189561 bytes, checksum: 2257ed5406d9bea6761289e1faa3308c (MD5) Previous issue date: 2016-05-23 / Não informada / This objective study aimed to analyze how the accountability of the State Legislative Assemblies of Brazil is implemented through its Electronic Portals, specifically focusing on measuring the level of transparency of the portals of the 26 Assemblies and Legislative Chamber of the Federal District, as well as its use as instruments of accountability, transparency and democracy, creating a General Ranking of Transparency Level and analyzing the variation predecessors research correlated in time lapse 2008, 2013 and 2016, also considering the geographical regions. Therefore, bibliographical research, as a literary basis to the topics related to the theme, and case research, considering the direct observation, were necessary, using qualitative and quantitative methodology of descriptive and explanatory nature. The model for the methodology, with due adaptations, was based on Zurra’s dissertation (2008) and Zurra’s, Botelho Ferreira’s and Smith’s article (2013), initially based on the Electronic Transparency Report of the Mexican Congress, organized by Non-Governmental Organization Monitor Legislativo prepared by Hernandez, Iturbe and Moreno (2003), which in turn was based on the Law of Transparency and Access to Governmental Public Information of Mexico. Thus, the model used now considered the availability of information on: administrative function; internal control; legislative work; work of the commissions; concessions, permits and contracts; historical archive and library services; external controls; and communication channels with society, 8 items subdivided into 44 sub-items. The measurement was made item by item, with a table of transparency for each one. After, a chart of the General Ranking of Transparency Level of the Legislative Assemblies is presented, which results from the sum of their respective ratings obtained in all the surveyed items. Finally, the survey results show an increase in levels of satisfactory and reasonable transparency. Also, the average for the region decreased in the following order: South, Southeast, Midwest, Northeast and North. The portals have the technology and procedures to function as instruments of accountability, transparency and democracy, but are not used to its fullest potential. The development of a mandatory standard layout simplified and intelligible access is therefore suggested, in order to promote greater social control and facilitate the oversight of External Control Bodies. / Esta pesquisa objetiva analisar de que forma se dá a prestação de contas das Assembleias Legislativas Estaduais do Brasil através de seus Portais Eletrônicos, especificamente tendo como foco mensurar o nível de transparência dos portais das 26 Assembleias e da Câmara Legislativa do Distrito Federal, bem como sua utilização como instrumentos de accountability, transparência e democracia, criando um Ranking Geral do Nível de Transparência e analisando a variação com pesquisas antecessoras correlacionadas no lapso temporal de 2008, 2013 e 2016, considerando também as regiões geográficas. Para tanto, fizeram-se necessárias as pesquisas bibliográfica, como base literária dos assuntos relativos ao tema, e de caso, considerando a observação direta, utilizando-se metodologia quali-quantitativa de cunho descritiva e explicativa. O modelo da metodologia, com as devidas adaptações, tomou como base a dissertação de Zurra (2008) e o artigo de Zurra, Botelho, Ferreira e Soares (2013), fundamentados inicialmente no informe sobre transparência eletrônica do Congresso mexicano, realizado pela Organização Não Governamental Monitor Legislativo, elaborado por Hernandez, Iturbe e Moreno (2003), tendo como base a Lei de Transparência e Acesso a Informações Públicas Governamentais do México. Assim, o modelo ora utilizado considerou a disponibilização de informações sobre: função administrativa; controle interno; trabalho legislativo; trabalho das comissões; concessões, permissões e contratos; arquivo histórico e serviços bibliotecários; controles externos; e canais de comunicação com a sociedade, sendo 8 itens subdivididos em 44 subitens. A mensuração foi feita item a item, apresentando uma tabela da transparência para cada item. Na sequência apresenta-se uma tabela com o Ranking Geral do Nível de Transparência das Assembleias Legislativas, a qual é resultante da somatória das suas respectivas notas obtidas em todos os itens pesquisados. Por fim, os resultados da pesquisa demonstram um crescimento nos níveis de transparência satisfatório e razoável. Ainda, a média por região decresceu na seguinte ordem: Sul, Sudeste, Centro-Oeste, Nordeste e Norte. Os portais possuem tecnologia e procedimentos para figurarem como instrumentos de accountability, transparência e democracia, mas não são utilizados em sua plenitude. Sugere-se portanto, o desenvolvimento de um layout padrão obrigatório de acesso simplificado e inteligível, de modo a promover maior controle social e facilitar a fiscalização dos Órgãos de Controle Externos.

Modeling of Enterprise Portals with Domain-Specific Language

Wasilewski, Dominik January 2012 (has links)
Enterprise portals are comprehensive solutions that enable centralized access to information and employees. They also support the business processes taking place in companies. The diversity of functionality offered by enterprise portals is the source of the complexity of the manufacturing process of such applications. Domain-Specific Languages (DSL) are a novel approach to solving problems associated with the software development. By limiting the possibilities of expression to the concepts related to a specific area Domain-Specific Languages are more focused on solving specific problems. The subject of this thesis is DSL SharePoint – Domain-Specific Language which supports the production of enterprise portals on Microsoft SharePoint platform. Language was developed with respect to the newest achievements in area of building DSLs. By applying the language in the industry, it was possible to verify the hypothesis that its usage positively affects the quality of software products. To this end, the quality model was built, and products made with the support of language have been compared to those developed in the traditional manner.

Doporučování se zaměřením na kulturní portály / Recommender systems for culture events

Vytisková, Zuzana January 2017 (has links)
The diploma thesis deals with the topic of recommendation in culture. In the theoretical part, it compares the recommendation of digitally available works with event recommendations, which serves as the basis for describing recommendations on the cultural portal. Further, the thesis examines the domain model as several different interconnected types of objects. Using these relations to enrich data sets allows overcoming the low data density and improving the recommendations. The paper examines two common situations of practical recommendation, general user recommendation with minimal profile and recommendation to registered users with known history. As a part of the solution, hybrid algorithms have been implemented based on the introducing content information into existing collaborative filtering methods. The results are verified in offline tests on data sets consisting of both research and real-world data. The subjective quality of the resulting recommendations was examined through a user study.

Ekonomie slevových kupónů / Economics of Discount Portals

Boušková, Veronika January 2013 (has links)
This thesis examines the effect of various factors on the sale of vouchers of group buying deals. The data for the analysis were collected from the website Slevomat for four weeks. The observation was performed daily at 8 a.m., 4 p.m., 12 a.m. Based on the existing literature and theoretical considerations, six hypotheses were formulated, three of which turned out to be consistent with the data. It was confirmed, that the decrease in time remaining till the end of the offer induces bigger amount of vouchers sold per time period. Positive reviews and the fact that the offer is displayed on the main page of Slevomat also positively influence the number of sold vouchers. The influence of the amount of earlier sold vouchers on the present purchases ("bandwagon effect") and of the size of the relative or absolute discount was not found. The "Monday effect", according to which sales should be lower at the beginning of the week, was also disproved.

Establishing a library portal for integrated e-resources at Modibbo Adama University of Technology, Yola, Adamawa State, Nigeria

Dauda, Joshua January 2018 (has links)
Philosophiae Doctor - PhD (Library and Information Studies) / The study examined the availability of e-resources in the Ibrahim Babangida Library at Modibbo Adama University of Technology, Yola (MAUTECH) focusing to integrate e-resources in a dedicated portal for easy access. The study was motivated by the Nigerian vision 20:2020 and the trend in 21st century academic libraries to offer electronic resources and services to meet users? demands and use of technology. Mixed methods were sequential, concurrent, conversion and integrated approaches used. A descriptive case study approach was employed. The Technology Acceptance Model (TAM) and Diffusion of Innovation (DoI) theories framed the study. Based on these, a conceptual framework was constructed. To achieve triangulation, questionnaires, interviews and scanning of library portals were used to gather both quantitative and qualitative data. Academics, students, academic librarians, and information and communication technology experts acted as participants. Findings reflected low use of the Ibrahim Babangida Library, dissatisfaction with the quality and quantity of the library collection, insufficient and unreliable Internet access on campus, limited information literacy education, familiarity and utilization of e-resources due to flexibility and easy access to academic information, need for digitisation of library resources and the need for a dedicated library portal. The study recommends, amongst others, information literacy education for students and academics, subscription to full-text databases, provision of sufficient and free Internet access, e-resource and e-services policies, and establishing a consortium with other Nigerian academic libraries. The outcome of the study was a designed, established and functioning library portal based on the input of all the stakeholders of the MAUTECH community.
