    ABSTRACT Semantic portals, such as socio-technical artifacts, involve different actors that are aligned to offer communication and information search services more quickly and accurately. The objective of this study is to describe the network of actors involved in the construction of semantic portals and their interrelationships. The precepts of the Actor-Network Theory were used as a methodology to design a network of semantic portals from selected studies in the literature. The results indicated that the design of the network of semantic portals points to actions of human actors: portal administrators, portal developers and end users, but also of non-human actors, which are made up mainly of technologies. Each actor has his or her interest contemplated as the other actors fulfill their roles towards a common goal - information of high added value. It can be concluded that the study of the features of the portal actors' network can guide changes in current standards, focusing on the quality of research results and the informational needs of the user community

    Na busca pela sustentabilidade no setor energético, a energia solar fotovoltaica (FV) vem-se destacando como solução para promover o desenvolvimento sustentável. À medida que a tecnologia FV se expande, surge a necessidade de estudos para a avaliação de como o novo mercado se comporta diante de diferentes cenários, com a consequente elaboração de indicadores diversos. Seguindo uma abordagem interdisciplinar e baseado no paradigma epistemológico da Design Science, o objetivo do presente estudo foi analisar, após seleção e avaliação, indicadores que reflitam um possível impacto da pandemia de COVID-19 no mercado de Micro e Minigeração Distribuída Fotovoltaica no Brasil (MMGD) nos anos de 2020 e 2021. Para tanto, caracterizou-se, por meio de revisão sistemática da literatura (RSL), o estado da arte a respeito do impacto da pandemia de COVID-19 no mercado fotovoltaico e de indicadores aplicados a sistemas fotovoltaicos. Com subsídios da RSL e conforme a literatura de base sobre o assunto, selecionou-se o indicador Potência Mensal Instalada de sistemas fotovoltaicos. Efetuou-se então a análise deste por meio de alimentação do indicador, por meio de consulta em banco de dados abertos da Agência Nacional de Energia Elétrica (ANEEL). Identificou-se que, com a sensibilização geral inicial causada pelo primeiro pico da pandemia de COVID-19, o mercado fotovoltaico sofreu redução na Potência Mensal Instalada; porém, passado esse momento inicial, observou-se a recuperação do indicador, o que sugere capacidade de resiliência e de adaptação desse mercado, superando as dificuldades e novos desafios encontrados e mantendo o ritmo de crescimento observado antes da pandemia.In the search for sustainability in the energy sector, photovoltaic solar energy (PV) has been highlighted as a solution to promote sustainable development. As PV technology expands, there is a need for studies to assess how the new market behaves in different scenarios with the consequent elaboration of different indicators. Following an interdisciplinary approach, and based on the epistemological paradigm of Design Science, the objective of this study was to analyse, preceded by selection and evaluation, indicators that reflect a possible impact of the COVID-19 pandemic on the Micro and Mini Photovoltaic Distributed Generation (MMDG) market in Brazil in 2020 and 2021. To do so, it was characterized through a systematic literature review - SLR, the state of the art about impact of the COVID-19 pandemic on the photovoltaic market and photovoltaic systems indicators. Subsidized by RSL and supported by the core literature on the subject, the Photovoltaic Systems Monthly Installed Power Capacity indicator was selected. Then, the analysis of this was carried out, by means of feeding the indicator using a query in the open database of the brazilian National Electric Energy Agency - ANEEL. It was identified that with the initial general awareness, caused by the first peak of the COVID-19 pandemic, the photovoltaic market suffered a reduction in the Monthly Installed Power Capacity, however, after this initial moment, the indicator recovered, suggesting a capacity for resilience and adaptation of this market, overcoming the difficulties and new challenges encountered, maintaining the pace of growth observed before the pandemic

    The quality of the information provided varies widely and the significant amount of accessible information makes it difficult to access relevant information. The aim of this study was to identify the use of indicators and metrics to assess the quality of data and information from white specialized literature available in the databases of Proquest, Web of Science and Scopus. The Prisma Recommendation Protocol and Content Analysis were used to identify the constructs, metrics and indicators used. The results showed the most frequent use of indicators of precision, reliability and completeness. There is a discrepancy and overlap of concepts in the definition of indicators that are associated with the type of indicator and the object of evaluation, that is, data or information. Assessment, context and content metrics were used to assess the quality of data, data sources and document information. The choice of indicators and metrics for analyzing the quality of information depends on the task and the subjective preferences of the information user, being preferable to use traceable, simple and easy-to-understand evaluation metrics.A qualidade de informa√ß√Ķes fornecidas varia amplamente e a expressiva quantidade de informa√ß√Ķes acess√≠veis dificulta o acesso √† informa√ß√£o relevante. O objetivo deste estudo foi identificar o uso de indicadores e de m√©tricas para avaliar a qualidade de dados e de informa√ß√Ķes a partir da literatura branca especializada dispon√≠vel nas bases de dados da Proquest, da Web of Science e da Scopus. O Protocolo de Recomenda√ß√£o Prisma e a An√°lise de Conte√ļdo foram utilizados para identificar construtos, m√©tricas e indicadores usados. Os resultados apontaram o uso mais frequente dos indicadores de precis√£o, de confiabilidade e de completude. Houve discrep√Ęncia e sobreposi√ß√£o de conceitos na defini√ß√£o dos indicadores, associadas ao tipo de indicador e ao objeto de avalia√ß√£o, ou seja, dado ou informa√ß√£o. As m√©tricas de avalia√ß√£o, de contexto e de conte√ļdo foram utilizadas para avaliar a qualidade de dados, fontes de dados e informa√ß√£o de documentos. Conclui-se que a escolha de indicadores e de m√©tricas para an√°lise da qualidade de informa√ß√£o depende da tarefa e das prefer√™ncias subjetivas do usu√°rio da informa√ß√£o, sendo prefer√≠vel usar m√©tricas de avalia√ß√£o rastre√°veis, simples e de f√°cil compreens√£o

Countries have been benchmarked on the e-government development and readiness indexes have been used to decision making. The aim of this paper is to investigate whether readiness benchmark on e-government can foster innovation. The result suggests that egovernment readiness indexes can foster some strategies related to technological or social innovation, and an innovation process measurement can improve the comprehension of the scenario

    COOPERATIVE NETWORKS FOR INNOVATION: A PANORAMA OF THE BRAZILLIAN SCENARIO BETWEEN 2003 AND 2011

    Get PDF
    The complexity of the innovation process and the difficulty faced by organizations when performing their required activities to stay active and competitive have led to a large number of companies towork in a network. This network enables the sharing of risks and resources, provides access to information and solutions, and facilitates research and development among other means of innovation with regard to products and processes. In this context, this paper mainly analyzes the setting for interorganizational cooperation for innovation in the Brazilian panorama between 2003 and 2011 based on data from the Innovation Research, known as PINTEC, elaborated by the Brazilian Institute of Geography and Statistics (IBGE). Through documental research, within a qualitative framework, secondary data were used, which were obtained from the PINTEC reports on cooperation among companies in Brazil, to construct a panorama of the cooperative scenario during the selected timeframe. The analysis revealed that, for the analyzed timeframe, Brazilian companies had most of their cooperative activities with the public with whom they maintain direct contact, such as their clients or consumers and suppliers. Furthermore, it revealed that actors such as universities or research institutes are not considered to be important for cooperative relationships or as information sources. As such, it can be inferred that cooperative activities for innovation are incipiente and are not considered as strategic activities by organizations in the Brazilian panorama

    This article presents the mapping of wiki tool functions in the organizational processes of knowledge management. Mapping these functions and their individual weights in the overall process will identify opportunities for decision-making and the optimization of knowledge sharing, a recognized asset in differentiation and organizational competitiveness. This is an exploratorydescriptive case study based on data collected from a questionnaire applied to 80 IT workers employed at a multinational company in Brazil. The use of mixed methods in data analysis was complemented by content analysis of the research corpus created. A theoretical model is graphically developed following Nonaka and Takeuchi’s knowledge spiral model (1997), a conventional model in knowledge management. In addition, an indicator of the individual contribution of each step in the conversion process of tacit into explicit knowledge is introduced. This case study alone does not enable a generalization of the findings. Therefore, a replication of the process and especially multiple testing of the constructed indicator are indispensable to its validation. Validation of the use of the wiki tool functions will allow the future development of measurements that can be directly employed in the organizational decision-making process. Statistically, a theoretical model is qualitatively discussed, which enables the construction of an initial indicator of the weight of individual contribution of steps in the knowledge generation process using the knowledge spiral model

    RESUMO¬†Os modelos tradicionais de recupera√ß√£o da informa√ß√£o utilizados na web s√£o inadequados para uma busca efetiva e r√°pida, e os resultados s√£o, comumente, numerosos e irrelevantes. Por outro lado, os modelos baseados em ontologias e tecnologias de web sem√Ęntica oferecem maior rapidez no acesso √†s informa√ß√Ķes com relev√Ęncia dos resultados. O objetivo desta pesquisa foi propor condi√ß√Ķes m√≠nimas necess√°rias para o estabelecimento de potencial sem√Ęntico de portais. Um question√°rio foi aplicado para coletar dados da equipe t√©cnica respons√°vel pelos portais de universidades p√ļblicas federais brasileiras da regi√£o Sul do Brasil, a fim de identificar ferramentas e tecnologias utilizadas nos portais. Como principais resultados, apresentam-se um diagn√≥stico do uso da ontologia na estrutura√ß√£o dos portais universit√°rios pesquisados e a proposi√ß√£o de um quadro de refer√™ncia das condi√ß√Ķes m√≠nimas necess√°rias para estabelecimento de potencial sem√Ęntico dos portais. Palavras-chave: Recupera√ß√£o de Informa√ß√£o Online; Ontologia; Web Sem√Ęntica; Portal; Universidades. ABSTRACT¬†Traditional models of information retrieval used on the web are inadequate for effective and quick search and the results are often numerous and irrelevant. On the other hand, models based on ontologies and semantic web technologies offer greater speed of access to information with relevant results. The goal of this research was to propose minimum necessary conditions for establishment of semantic potential of gateways. A questionnaire was used to collect data from the technical team responsible for homepages of federal public universities in southern Brazil, in order to identify tools and technologies used in these homepages. The main results presented were a diagnosis of ontology use in structuring the investigated university portals and the proposal of a framework containing the minimum necessary conditions to establish their semantic potential.
