The importance of clusters for the development of small & medium enterprises

This thesis aims to open a theoretical discussion on the importance of cluster for the development of Small and Medium Enterprises. The methodology applied was based on bibliographical and qualitative research. The basic questions raised by this study can be summarized as follows: How the creation of a cluster will help in the development of the SME?. Consequently, the final objective of the work is to identify which are the characteristics that help into the success of a Small & Medium Enterprises inserted in a cluster. The answer to this question led the research to a better understanding of (i) the characterization of the Small & Medium Enterprises; (ii) the clusters theory; (iii) evidence for a developed (Italy) and a developing (Chile) country that support our proposition to verify. The main results confirm the relevance of the cluster for the development of the Small and Medium Enterprises because of the collective efficiency that generates, improving the funding conditions, the exporter capacity and diminishing the activities costs of the small companies that are part of the conglomerate.

O que é Creative Commons?: novos modelos de direito autoral em um mundo mais criativo

Os direitos autorais encontram-se no centro do mundo. Se antes interessavam apenas a quem publicava livros, gravava músicas ou produzia filmes, hoje os direitos autorais dizem respeito a todos os que acessam a internet. Afinal, o recente desenvolvimento tecnológico passou a permitir que obras culturais sejam produzidas e distribuídas diariamente no universo digital. Contudo, as leis de direitos autorais no Brasil não estão adequadas às práticas do tempo presente. Por isso, iniciativas inovadoras, que surgem em conformidade com a lei e que têm por objetivo aproximar o artista do público, vêm ganhando importância. Este livro é sobre uma dessas iniciativas - as licenças Creative Commons. Por meio das licenças Creative Commons o autor pode comunicar ao público o modo como ele permite que sua obra seja usada. A partir de uma variedade de seis licenças (que permitem desde a simples cópia até a exploração comercial da obra, conforme escolha do autor), as obras licenciadas podem fomentar a educação, incentivar a criação de obras derivadas ou permitir projetos colaborativos. Tudo de acordo com a vontade do autor e em favor de um mundo mais criativo.

Demand- side resistance to creative destruction in schumpeterian growth theory

The Schumpelerian model of endogeno~s growlh is generalized with lhe introduction of stochastic resislance. by agenls other Ihan producers. to lhe innovations which drive growth. This causes a queue to be formcd of innovations, alrcady discovered, bUI waiting to be adopled~ A slationary stochastic equilibrium (SSE) is obtained when the queue is stable~ It is shown that in the SSE, such resistance will always reduce lhe average growth iate hut it may increa~e wclfare in certain silualions. In an example, Ihis is when innovatiuns are small anti monopoly power great. The cont1icl hetween this welfare motive for resistance and those of rent-seeking innovalors.may well explain why growth rates differ.

Pesquisa e desenvolvimento (P&D) em clusters empresariais

Nos clusters empresariais, a proximidade geográfica e cultural pode viabilizar o acesso especial a relacionamentos pessoais, qualidade em informação, e fortes incentivos ao aumento da produtividade e da inovação. Esses benefícios são importantes não só para as empresas em concorrência, mas também para as demais organizações do entorno. A partir deste quadro de referências, esta pesquisa tem como objetivo determinar como as atividades de pesquisa e desenvolvimento (P&D) podem ser utilizadas estrategicamente pelos agentes econômicos localizadas em um cluster de empresas exportadoras e intensivas em conhecimento. A pesquisa, que estudou 18 empresas âncoras do cluster de tecnologia da informação e comunicação (TIC) da região metropolitana de Campinas (RMC), revelou que os benefícios da localização são aproveitados pelas empresas, e de forma estratégica, pois resultados relacionados ao aumento da competitividade da operação no Brasil podem ser observados na amostra estudada.

Speculative bubbles and contagion: analysis of volatility’s clusters during the DotCom bubble based on the dynamic conditional correlation model

Revendo a definição e determinação de bolhas especulativas no contexto de contágio, este estudo analisa a bolha do DotCom nos mercados acionistas americanos e europeus usando o modelo de correlação condicional dinâmica (DCC) proposto por Engle e Sheppard (2001) como uma explicação econométrica e, por outro lado, as finanças comportamentais como uma explicação psicológica. Contágio é definido, neste contexto, como a quebra estatística nos DCC’s estimados, medidos através das alterações das suas médias e medianas. Surpreendentemente, o contágio é menor durante bolhas de preços, sendo que o resultado principal indica a presença de contágio entre os diferentes índices dos dois continentes e demonstra a presença de alterações estruturais durante a crise financeira.

On paternalistic leadership fit: exploring cross-cultural endorsement, leader-follower fit, and the boundary role of organizational culture

Although cross-cultural leadership research has thrived in international business literature, little attention has been devoted to understanding the effectiveness of non-western theories beyond their original contexts. The purpose of this study is to examine the cross-cultural endorsement of paternalistic leadership, an emerging non-western leadership theory, using data from GLOBE project. Using multigroup confirmatory factor analyses we found measurement equivalence of a scale derived from GLOBE’s data, which enabled us to compare the endorsement of paternalistic leadership dimensions across 10 cultural clusters and 55 societies. Our study revealed that there are significant differences in the importance societies give to each dimension, suggesting that paternalism as leadership style is not universally nor homogeneously endorsed. Furthermore, results suggest that different patterns of endorsement of each of these dimensions give rise to idiosyncratic shades of paternalistic leadership across societies. Implications for theory and future research on international business are discussed.

The creative and advanced technology economy in Brazil: executive summary

Speculative bubbles and contagion: analysis of volatility's clusters during the DotCom bubble based on the dynamic conditional correlation model

Reviewing the de nition and measurement of speculative bubbles in context of contagion, this paper analyses the DotCom bubble in American and European equity markets using the dynamic conditional correlation (DCC) model proposed by (Engle and Sheppard 2001) as on one hand as an econometrics explanation and on the other hand the behavioral nance as an psychological explanation. Contagion is de ned in this context as the statistical break in the computed DCCs as measured by the shifts in their means and medians. Even it is astonishing, that the contagion is lower during price bubbles, the main nding indicates the presence of contagion in the di¤erent indices among those two continents and proves the presence of structural changes during nancial crisis

Análise de clusters aplicada ao sucesso/insucesso em matemática

De acordo com [Mirkin B., 1996], classificação é um agrupamento existente ou ideal daqueles que se parecem (ou são semelhantes) e separação dos que são dissemelhantes. Sendo o objectivo/razão da classificação: (1) formar e adquirir conhecimento, (2) analizar a estrutura do fenómeno e (3) relacionar entre si diferentes aspectos do fenómeno em questão. No estudo do sucesso/insucesso da Matemática está de algum modo subjacente nos nossos objectivos “classificar” os alunos de acordo com os factores que se pretende que sejam determinantes nos resultados a Matemática. Por outro lado, voltamos a recorrer à classificação quando pretendemos estabelecer os tipos de factores determinantes nos resultados da Matemática. Os objectivos da Análise de Clusters são: (1) analisar a estrutura dos dados; (2) verificar/relacionar os aspectos dos dados entre si; (3) ajudar na concepção da classificação. Pensámos que esta técnica da análise exploratória de dados poderia representar uma ferramenta muito potente para o estudo do sucesso/insucesso da Matemática no Ensino Básico. O trabalho desenvolvido nesta dissertação prova que a Análise de Clusters responde adequadamente às questões que se podem formular quando se tenta enquadrar socialmente e pedagogicamente o sucesso/insucesso da Matemática.

Theoretical study of the structure and stability of NbxOy, and NbxOy+ (x = 1-3; y = 2-5, 7, 8) clusters

Geometric, thermodynamic and electronic properties of cluster neutrals NbxOy and cations NbxOy+ (x = 1-3; y = 2-5, 7, 8) have been characterized theoretically. A DFT calculation using a hybrid combination of B3LYP with contracted Huzinaga basis sets. Numerical results of the relative stabilities, ionization potentials and band gaps of different clusters are in agreement with experiment. Analysis of dissociation channels supports the more stable building blocks as formed by NbO2, NbO2+ NbO3 and NbO3+ stoichiometries. The net atomic charges suggest that oxygen donor molecules can interact more favorably on central niobium atoms of cluster cations, while the interaction with oxygen acceptor molecules is more favorable on the terminal oxygen atoms of neutral clusters. A topological analysis of the electron localization function gradient field indicates that the clusters may be described as having a strong ionic interaction between Nb and O atoms.

Uma nova forma de calcular os centros dos Clusters em algoritmos de agrupamento tipo fuzzy c-means

Clustering data is a very important task in data mining, image processing and pattern recognition problems. One of the most popular clustering algorithms is the Fuzzy C-Means (FCM). This thesis proposes to implement a new way of calculating the cluster centers in the procedure of FCM algorithm which are called ckMeans, and in some variants of FCM, in particular, here we apply it for those variants that use other distances. The goal of this change is to reduce the number of iterations and processing time of these algorithms without affecting the quality of the partition, or even to improve the number of correct classifications in some cases. Also, we developed an algorithm based on ckMeans to manipulate interval data considering interval membership degrees. This algorithm allows the representation of data without converting interval data into punctual ones, as it happens to other extensions of FCM that deal with interval data. In order to validate the proposed methodologies it was made a comparison between a clustering for ckMeans, K-Means and FCM algorithms (since the algorithm proposed in this paper to calculate the centers is similar to the K-Means) considering three different distances. We used several known databases. In this case, the results of Interval ckMeans were compared with the results of other clustering algorithms when applied to an interval database with minimum and maximum temperature of the month for a given year, referring to 37 cities distributed across continents

Direito autoral e tecnologias de informação e comunicação no contexto da produção, uso e disseminação de informação: um olhar para as Licenças Creative Commons

The development of information and communication technologies, in particular, Internet, and its Web 2.0 information environment has led to significant changes in contemporary society as to the ways of producing informational content. Collaboration and remix, favored by the new services and applications resulting from the development of the Web, are practices which contribute for the exponential growth of information producers. An important part of humanity ceases to be a mere consumer of symbolic goods and becomes a member in a society that sees in the collaboration and remix a new form of creation, use and dissemination of intellectual content. However, as such practices involve the production and use of information intelectual content, and are ruled by a legisltion which determine determines under what conditions the author and the user must produce and use the intellectual work. This legislation established for a context prior to the develompment of the Web has created an imbalance in the context of Web 2.0 which needs to be solved in some way so as to provide the required rebalance for the flow of information. This study explores the collaborative Web environment, the scope of copyright law in Web enviroment and the Creative Commons licenses as an alternative for producers and users of information to create, recreate, share, use, reuse and disseminate legally the intellectual production for the benefit of the construction of knowledge.
