O setor de venture capital, as startups e o empreendedorismo em Israel, nos anos recentes

Some of the factors that help to explain the Israeli success case on promoting high-tech start-ups backed by venture capital funds can be found in the risk-taking culture of the country, the vast technological know-how associated with the huge military development, the high offer of human intellectual capital due to the immigration processes, and finally also the FDI inflows, mainly from the United States. Even though, these factors would not have the same effects in the economy unless the right structures were founded by the public-private sectors partnerships for the high-tech industry development and the adaptation of the investment industry surpasses two of the deepest global financial crisis: the dot-com bubble in the 2000’s and the subprime in 2008

Políticas Industriais e de Ciência, Tecnologia e Inovação na Irlanda: ênfase em setores de alta tecnologia e comparação com o Brasil

From a theoretical foundation favorable to industrial policies, this paper intends to show the main policies followed by Ireland since the 1950s, with a special emphasis on those directed to Science, Technology and Innovation (S,T&I), FDI and high tech sectors, like software and biotechnology. We compare these policies with those used in Brazil, in a similar period, in order to have some hints for virtual transformations of current Brazilian policies. We conclude that the compromise of the State with the direction of the development and the continu-ity of industrial policies is very important to a solid building of comparative advantages in technologically dynamic sectors.

Strategic planning for dairy cattle: SWOT analysis applied to a property of a farmers' association in Dracena, São Paulo state, Brazil

The sector of milk production in Brazil is very heterogeneous (high-tech in large scale X family properties). This study aimed to develop a diagnostic as a basis for a strategic plan to face the challenges inherent in operating a dairy farm in property of a farmers' association in Dracena, São Paulo, Brazil. It was observed that the association needs a more efficient guidance in the marketing, production and finance areas, not to compromise the search for new markets and continued growth in activity.

Participative site-specific agriculture analysis for smallholders

Site-specific agriculture has been adopted in a high-tech context using, for instance, in situ sensors, satellite images for remote sensing analysis, and some other technological devices. However, farmers and smallholders without the economic resources and required knowledge to use and to access the latest technology seem to find an impediment to precision agricultural practices. This article discusses the possibility of adopting precision agriculture (PA) principles for site-specific management but in a low technology context for such farmers. The proposed methodology to support PA combines low technology dependency and a participatory approach by involving smallholders, farmers and experts. The case studies demonstrate how the interplay of low technology and a participative approach may be suitable for smallholders for site-specific agriculture analysis.

Development of a supplier and purchase order management product/service under the 4PL logistics concept: a case study

Supply chain starts with a demand arisen and ends with material transport and delivery at its final destination. With this in mind, most of manufacturing, processors or distribution companies of consumer goods, spare parts and components for production, processing and finished goods, within national or international markets, may not have information and control over its supply chain performance. This article presents concept and logistics models evolution, purchase order and international supplier management, control tower and its logistics information systems. This also presents a real process implementation for a global high tech manufacturer company.

Knowledge Flows and Networks: the Interplay between Local and Global Linkages within Bangalore IT Cluster

This doctoral work gains deeper insight into the dynamics of knowledge flows within and across clusters, unfolding their features, directions and strategic implications. Alliances, networks and personnel mobility are acknowledged as the three main channels of inter-firm knowledge flows, thus offering three heterogeneous measures to analyze the phenomenon. The interplay between the three channels and the richness of available research methods, has allowed for the elaboration of three different papers and perspectives. The common empirical setting is the IT cluster in Bangalore, for its distinguished features as a high-tech cluster and for its steady yearly two-digit growth around the service-based business model. The first paper deploys both a firm-level and a tie-level analysis, exploring the cases of 4 domestic companies and of 2 MNCs active the cluster, according to a cluster-based perspective. The distinction between business-domain knowledge and technical knowledge emerges from the qualitative evidence, further confirmed by quantitative analyses at tie-level. At firm-level, the specialization degree seems to be influencing the kind of knowledge shared, while at tie-level both the frequency of interaction and the governance mode prove to determine differences in the distribution of knowledge flows. The second paper zooms out and considers the inter-firm networks; particularly focusing on the role of cluster boundary, internal and external networks are analyzed, in their size, long-term orientation and exploration degree. The research method is purely qualitative and allows for the observation of the evolving strategic role of internal network: from exploitation-based to exploration-based. Moreover, a causal pattern is emphasized, linking the evolution and features of the external network to the evolution and features of internal network. The final paper addresses the softer and more micro-level side of knowledge flows: personnel mobility. A social capital perspective is here developed, which considers both employees’ acquisition and employees’ loss as building inter-firm ties, thus enhancing company’s overall social capital. Negative binomial regression analyses at dyad-level test the significant impact of cluster affiliation (cluster firms vs non-cluster firms), industry affiliation (IT firms vs non-IT fims) and foreign affiliation (MNCs vs domestic firms) in shaping the uneven distribution of personnel mobility, and thus of knowledge flows, among companies.

Strukturbildung in dünnen Filmen aus Mischungen statistischer Copolymere

Dünne Polymerfilme besitzen einen weiten Anwendungsbereich in vielen High-Tech Applikationen. All diese Anwendungen erfordern ein bestimmtes Anwendungsprofil des dünnen Films. Diese Anforderungen umschließen sowohl die physikalischen Eigenschaften des Films als auch seine Struktur. Um sie zu realisieren, werden oftmals Mischungsfilme aus verschiedenen Polymeren verwendet. Diese neigen jedoch in vielen Fällen zur bereits während der Präparation zu Phasenseparation.Vor diesem Hintergrund wurde untersucht welchen Einfluss die Verträglichkeit der gemischten Polymere auf die Strukturbildung des dünnen Films ausüben. Als Modellsystem hierfür dienten Mischungen statistischer Poly-styrol-stat-para brom-styrol Copolymere.Die Oberflächenstrukturen, die sich währen der Präparation der Mischungsfilme einstellten, wurden mit Rasterkraftmikroskopie untersucht. wobei die Topologie einer statistischen Analyse unterzogen wurde. Zum einen wurde hierzu die spektrale Leistungsdichte der Oberflächenkontour zum anderen die zugehörigen Minkowski-Funktionale berechnet.Neben Oberflächenstrukturen bilden sich während der Präparation auch Entmischungsstrukturen im inneren des Filmes. Zur Charakterisierung dieser Strukturen wurden die Filme durch Streuung unter streifendem Einfall untersucht. Durch eine modellfreie Interpretation der Streuexperimente gelang der Nachweis der inneren StrukturenFür nur schwach unverträglich Filme konnte auf Basis der Streuexperimente eine Replikation der Oberflächenstruktur des Substrates auf die Filmoberflächen nachgewiesen werden. Diese Replikation wurde für verschieden raue Substrate und bezueglich der Kinetik ihrer Abnahme beim Quellen der Filme untersucht.

Power consumption analysis for self-diagnosis of Wireless Sensor Nodes

Wireless sensor networks can transform our buildings in smart environments, improving comfort, energy efficiency and safety. Today however, wireless sensor networks are not considered reliable enough for being deployed on large scale. In this thesis, we study the main failure causes for wireless sensor networks, the existing solutions to improve reliability and investigate the possibility to implement self-diagnosis through power consumption measurements on the sensor nodes. Especially, we focus our interest on faults that generate in-range errors: those are wrong readings but belong to the range of the sensor and can therefore be missed by external observers. Using a wireless sensor network deployed in the R\&D building of NXP at the High Tech Campus of Eindhoven, we performed a power consumption characterization of the Wireless Autonomous Sensor (WAS), and studied through some experiments the effect that faults have in the power consumption of the sensor.

Farbe und Funktion neuer Molekülarchitekturen auf Rylencarbonsäureimid-Basis

Perylencarbonsäureimide sind Farbmittel mit ausgezeichneter chemischer und photochemischer Stabilität, hohen molaren Extinktionskoeffizienten und hohen Fluoreszenzquantenausbeuten, weswegen ihre Anwendung über die reine Farbgebung hinausgeht und von der Grundlagenforschung bis hin zum funktionellen High-Tech-Material reicht. Ziel der vorliegenden Dissertation mit dem Titel „Farbe und Funktion neuer Molekülarchitekturen auf Rylencarbonsäureimid-Basis“ war die Synthese und Charakterisierung von neuen chromophoren Systemen ausgehend von bekannten Perylenfarbmitteln. Im ersten Teil der Arbeit wird die Synthese eines Konstruktes beschrieben, das es ermöglicht, die Rotation eines Perylenfarbstoffs einzelmolekülspektroskopisch zu visualisieren. Mit der Methode der defokussierten Einzelmolekülspektroskopie kann die Immobilisierung des molekularen Rotors nachgewiesen und die Umorientierung des Farbstoffs detektiert werden. In den folgenden Kapiteln steht die gezielte Variation bekannter chromophorer Systeme im Vordergrund. Die Veränderung der Größe, der Topologie und der Substitution des aromatischen π-Systems hat erheblichen Einfluss auf die optischen Eigenschaften sowie auf die Eignung der Moleküle als funktionelle Farbmittel, beispielsweise in optoelektronischen Bauteilen. Anhand der Eigenschaften der dargestellten Derivate können systematische Zusammenhänge zwischen Struktur, Farbe und Funktion abgeleitet werden.

Three essays in industrial organization

This dissertation comprises three essays on the topic of industrial organization. The first essay considers how different intellectual property systems can affect the incentives to invest in R&D when innovation is cumulative. I introduce a distinction between plain and sophisticated technological knowledge, which plays a crucial role in determining how different appropriability rules affect the incentives to innovate. I argue that the positive effect of weak intellectual property regimes on the sharing of intermediate technological knowledge vanishes when technological knowledge is sophisticated, as is likely to be the case in many high tech industries. The second essay analyzes a two-sided market for news where advertisers may pay a media outlet to conceal negative information on the quality of their own product (paying positive to avoid negative) and/or to disclose negative information on the quality of their competitors products (paying positive to go negative). It is shown that whether advertisers have negative consequences on the accuracy of media reports or not, ultimately depends on the extent of correlation among advertisers products. The third essay considers the role of social learning in the diffusion of a new technology. A population of agents can choose between two risky technologies: an old one for which they know the expected outcome, and a new one for which they have only a prior. Different environments are confronted. In the benchmark case agents are isolated and can perform costly experiments to infer the quality of the new technology. In the other cases agents are settled in a network and can observe the outcomes of neighbors. We observe that in expectations the quality of the new technology may be overestimated when there is a network spread of information.
