Teorias em estratégia

A estratégia empresarial é uma disciplina jovem. Comparado com os campos de estudo de economia e sociologia o campo de estratégia empresarial pode ser visto como um fenômeno de formação mais recente, embora extremamente dinâmico em sua capacidade de criar abordagens teóricas diferenciadas. Este trabalho discute a recente proliferação de teorias em estratégia empresarial, propondo um modelo de classificação destas teorias baseado na análise empírica do modelo de escolas de pensamento em estratégia empresarial desenvolvido por Mintzberg, Ahlstrand e Lampel em seu livro Safári de Estratégia (1998). As possíveis conseqüências relativas à interação entre teoria e prática são também discutidas apresentando o que definimos como a síndrome do ornitorrinco.

Análise de redes em procedimentos de cooperação indireta: utilização no sistema de recomendações da Biblioteca Karl A. Boedecker

Sistemas de recomendação baseados cooperação indireta podem ser implementados em bibliotecas por meio da aplicação de conceitos e procedimentos de análise de redes. Uma medida de distância temática, inicialmente desenvolvida para variáveis dicotômicas, foi generalizada e aplicada a matrizes de co-ocorrências, permitindo o aproveitando de toda a informação disponível sobre o comportamento dos usuários com relação aos itens consultados. Como resultado formaram-se subgrupos especializados altamente coerentes, para os quais listas-base e listas personalizadas foram geradas da maneira usual. Aplicativos programáveis capazes de manipularem matrizes, como o software S-plus, foram utilizados para os cálculos (com vantagens sobre o software especializado UCINET 5.0), sendo suficientes para o processamento de grupos temáticos de até 10.000 usuários.

A influência dos ativos intangíveis na análise de risco de crédito de empresas de base tecnológica

Evolution is present in world dynamics. And it is just in such transformational environment where companies have been encapsulated. In an economy of knowledge, physical assets alone are unable to provide profits to meet shareholders' demands. Now there comes an invisible component with the purpose of defining strategies and impelling results: Intangible Assets. Banking financing systems, however, have not kept pace with this knowledge revolution and its resulting new income generation techniques. Credit analysis methods for most financing agents would not employ any intangible parameters in their methodology of study as yet. This paper seeks to discuss the importance of intangible assets by focusing their role of influencial factor in decisions to finance technology-based companies. By studying the credit risk classification system employed by FINEP, Brazil's Federal Agency for innovation development, we wished to suggest indicators for intangibles which might be put to use in the Financiadora.

Election over, battle for Brazil rages

Last week I sat down with a Brazilian acquaintance who was shaking his head over the state of national politics. A graduate of a military high school, he'd been getting e-mails from former classmates, many of them now retired army officers, who were irate over the recent presidential elections. "We need to kick these no-good Petistas out of office," one bristled, using the derogatory shorthand for members of the ruling Workers Party, or PT in Portuguese.

Brazil's election: as polarized as can be

What you see above is a graphic representation of something anyone who followed the campaign that led to the re-election of Dilma Rousseff as Brazil’s president on October 26 already knows: the election was the most polarised in the country’s history. Brasil was split down the middle, not only numerically (Dilma got 52 per cent, Aécio Neves 48) and geographically (Dilma won in the less developed north, Aécio in the more prosperous south). The twitterspere, too, was divided into two camps. Not only that; they hardly talked to each other at all.

Mundos pequenos, produção acadêmica e grafos de colaboração: um estudo de caso dos Enanpads

Utilizando a base de dados dos trabalhos publicados nos Enanpads realizados em 2002-04, este artigo focaliza a área de administração da informação para realizar um estudo exploratório sobre a formação de padrões nas estruturas de disseminação do conhecimento acadêmico no Brasil, apoiado nos conceitos oriundos da análise das redes sociais e conjugados com a base proveniente da teoria dos grafos e em recursos computacionais. Procurou-se mapear os fluxos de informações que possibilitam as trocas de conhecimento através das ligações existentes no meio acadêmico. Os resultados indicam a necessidade de ampliar e estreitar os laços entre os autores, notadamente os que possuem algum grau de centralidade local, no intuito de obter o fortalecimento das instituições de ensino, de forma a quebrar as resistências à produção conjunta entre elas, em detrimento do padrão de reprodução endógena detectado.

Histórias de empreendedores: significados, narrativas e artefatos

Compreender o processo de significação e ressignificação que o empreendedor atribui ao novo negócio através das etapas de busca, percepção e interpretação propostas por Daft e Weick (1984) ao longo do tempo. Design/metodologia/abordagem: Sob uma perspectiva interpretativista, este trabalho se valeu de abordagens qualitativas. Foram utilizadas téc nicas de análise de narrativas, antenarrativas e análise de dados qualitativos sobre entrevistas realizadas com 11 empreendedores digitais em dois momentos diferentes. Descobertas: as análises sugerem que o empreendedor ressignifica seu negócio com o passar do tempo, provavelmente em função do nível de sucesso do empreendimento. Esta pesquisa corrobora a proposição de Daft & Weick (1984) acerca da existência de um processo cíclico de busca, interpretação e ação que levaria a um contínuo de ressignificações. Implicações da pesquisa: Para os empreendedores (practioners), este trabalho lança luz sobre as possibilidades de uso das narrativas como recursos para influência e disseminação de significados (sensegiving). Para acadêmicos, este trabalho oferece melhor conceituação do constructo ‘artefato estratégico’, além de avançar na consolidação dos métodos de análise de narrativas. Originalidade/Valor: O valor dessa pesquisa se dá em fortalecer os métodos de análise de narrativas, além de apresentar um possível caminho para capturar os elementos de ressignificação. Além disso, ao propor um framework de análise e construção de narrativas empreendedoras, este trabalho pode auxiliar pesquisadores e practioners

DAPP analyzes British elections in post in the Financial Times

Everything before the election seemed to be pointing to a Labour lead. Even pollsters got it wrong. But a network analysis of the Twitter conversations about the general election highlights just how much hype there was around Labour in the run-up to the big day. Marco Ruediger and this colleagues at the department of public policy analysis at the Fundação Getulio Vargas in Rio de Janeiro analysed and visualised millions of tweets during the campaign.

BlueFriends: measuring, analyzing and preventing social exclusion between elementary school students

Social exclusion is a relatively recent term, whose creation is attributed to René Lenoir(Lenoir, 1974). Its concept covers a remarkably wide range of social and economic problems, and can be triggered for various reasons: mentally and physically handicapped, abused children, delinquents, multi-problem households, asocial people, and other social “misfits” (Silver, 1995, pp. 63; Foucault, 1992). With an increasingly multi-cultural population, cultural and social inequalities rapidly ascend, bringing with them the need for educational restructuring. We are living in an evermore diverse world, and children need to be educated to be receptive to the different types of people around them, especially considering social and cultural aspects. It is with these goals that inclusive education has seen an increased trend in today’s academic environment, reminding us that even though children may be taught under the same roof, discriminatory practices might still happen. There are, however, a number of developed tools to assess the various dimensions of social networks. These are mostly based on questionnaires and interviews, which tend to be fastidious and don’t allow for longitudinal, large scale measurement. This thesis introduces BlueFriends, a Bluetooth-based measurement tool for social inclusion/exclusion on elementary school classes. The main goals behind the development of this tool were a) understanding how exclusion manifests in students’ behaviors, and b) motivating pro-social behaviors on children through the use of a persuasive technology. BlueFriends is a distributed application, comprised by an application running on several smartphones, a web-hosted database and a computer providing a visual representation of the data collected on a TV screen, attempting to influence children behaviors. The application makes use of the Bluetooth device present on each phone to continuously sample the RSSI (Received Signal Strength Indication) from other phones, storing the data locally on each phone. All of the stored data is collected, processed and then inserted into the database at the end of each day. At the beginning of each recess, children are reminded of how their behaviors affect others with the help of a visual display, which consists of interactions between dogs. This display illustrates every child’s best friends, as well as which colleagues they don’t interact with as much. Several tips encouraging social interaction and inclusiveness are displayed, inspiring children to change their behaviors towards the colleagues they spend less time with. This thesis documents the process of designing, deploying and analyzing the results of two field studies. On the first study, we assess how the current developed tools are inferior to our measuring tool by deploying a measurement only study, aimed at perceiving how much information can be obtained by the BlueFriends application and attempting to understand how exclusion manifests itself in the school environment. On the second study, we pile on the previous to try and motivate pro-social behaviors on students, with the use of visual cues and recommendations. Ultimately, we confirm that our measurement tool’s results were satisfying towards measuring and changing children’s behaviors, and conclude with our thoughts on possible future work, suggesting a number of possible extensions and improvements.

O coração e o dragão: perspectivas da vida urbana em uma cidade fragmentada

This research aims to study dimensions of urban life in the contemporaneous city. It is an effort to understand the functioning of the contemporary city as an artifact that somehow affects social relations. The study focuses on the limits and possibilities of urbanity in the city today, understanding urbanity as a set of factors that favor wealth, diversity and spontaneity of public life. The research aims to show that cities today tend to criate fragmented urban life into at least one of the three urbanity dimensions: spatial dimension, social and temporal dimension. The study involves the analysis of two public spaces in Fortaleza (Praça do Ferreira and the open urban public spaces of the Centro Cultural Dragão do Mar), using Space Syntax Analysis methods and for Post Occupancy Evaluation procedures. Research shows that temporal dimension of urbanity is limited in the public spaces studied. In Praça do Ferreira, spatial and social dimensions are present, but their effects are limited by the temporal dimension. The Dragão do Mar, on the other hand, the spatial and social dimensions of urban life are more limited and more concentrated in time

Ecomorfologia de dez espécies de peixes marinhos mais abundantes de Galinhos/RN

Ecomorphology is a science based on the idea that morphological differences among species could be associated with distinct biological and environmental pressures suffered by them. These differences can be studied employing morphological and biometric indexes denominated Ecomorphological attributes , representing standards that express characteristics of the individual in relation to its environment, and can be interpreted as indicators of life habits or adaptations suffered due its occupation of different habitats. This work aims to contribute for the knowledge of the ecomorphology of the Brazilian marine ichthyofauna, specifically from Galinhos, located at Rio Grande do Norte state. 10 different species of fish were studied, belonging the families Gerreidae (Eucinostomus argenteus), Haemulidae (Orthopristis ruber,Pomadasyscorvinaeformis,Haemulonaurolineatum,Haemulonplumieri,Haemulonsteindachneri), Lutjanidae (Lutjanus synagris), Paralichthyidae (Syaciummicrurum), Bothidae (Bothus ocellatus) and Tetraodontidae (Sphoeroidestestudineus), which were obtained during five collections, in the period time of September/2004 to April/2005, utilizing three special nets. The ecomorphological study was performed at the laboratory. Eight to ten samples of each fish specie were measured. Fifteen morphological aspects were considered to calculate twelve ecomorphological attributes. Multivariate statistical analysis methods such as Principal Component Analysis (PCA) and Cluster Analysis were done to identify ecmorphological patterns to describe the data set obtained. As results, H.aurolineatumwas the most abundant specie found (23,03%) and S.testudineusthe less one with 0,23%. The 1st Principal component showed variation of 60,03% with influence of the ecomorphological attribute related to body morphology, while the 2nd PC with 23,25% variation had influence of the ecomorphological attribute related to oral morphology. The Cluster Analiysis promoted the identification of three distinct groups Perciformes, Pleuronectiformes and Tetraodontiformes. Based on the obtained data, considering morphological characters differences among the species studied, we suggest that all of them live at the medium (E.argenteus,O.rubber, P.corvinaeformis,H.aurolineatum,H.plumieri,H.steindachneri,L.synagris) and bottom (S.micrurum,B.ocellatus,S.testudineus) region of column water.
