GaN epilayers grown at high growth rate using gas source molecular beam epitaxy method

High-quality GaN epilayers have been grown by gas source molecular beam epitaxy using ammonia as the nitrogen source. During the growth, the growth rate is up to 1.2 mu m/h and can be varied from 0.3 to 1.2 mu m. The unintentional n-type doping as low as 7x10(17) cm(-3) was obtained at room temperature. Low-temperature photoluminescence spectrum was dominated by near-edge emission without deep-level related luminescence, indicative of high-quality epilayers. (C) 1998 Elsevier Science B.V.

Marketing performance measurement : overview of approaches and practices for high technology firms

Um levantamento de 320 executivos de marketing feito pelo Conselho CMO e divulgado em junho de 2004 indicou que poucas companhias de alta tecnologia (menos de 20% das empresas entrevistadas) têm desenvolvido medidas e métricas úteis e expressivas para as suas organizações de marketing. Porém a pesquisa também revelou que companhias que estabeleceram medidas formais e compreensivas atingiram resultados financeiros superiores e tiveram mais confiança do CEO na função de marketing. Esta dissertação provê uma visão geral da informação precisa para executivos de marketing entenderem e implementarem processos para medição de performance de marketing (MPM) em suas organizações. Ela levanta questões para gerentes de marketing na industria de alta tecnologia com respeito às demandas para maior responsabilidade final, valor de medição para o melhoramento dos processos de marketing, iniciativas para determinar a lucratividade dos investimentos em marketing, e a importância das atividades de marketing nos relatórios corporativos. Esta dissertação defende a implementação de MPM, mapeando seus benefícios de medição para ambos gerentes de marketing e as suas empresas. o trabalho logo explora alguns conceitos gerais de medição de marketing e investiga algumas abordagens a MPM propostas pela industria, pela comunidade acadêmica, e pelos analistas. Finalmente, a dissertação descreve algumas práticas que todo gerente de marketing na industria de alta tecnologia deve considerar quando adotando MPM. As sugestões são gerais, mas devem familiarizar o leitor com as informações precisas para habilitar processos e rigor na sua organização com respeito a MPM.

Integration of R&D and new product development: case studies of Brazilian high-tech firms

One of the aspects that influence good performance of new product development (NPD) at high-tech companies is the integration of research and development (R&D) and the other functions involved with NPD. The objective of this paper is to examine why Brazilian medium and large sized high-tech companies are different with respect to the integration of R&D with NPD. An analysis of case studies was conducted at five Brazilian high-tech firms. Among the results, collectivism, which is characteristic of the Brazilian organisational culture, was seen to manifest itself in companies through the adoption of cross-functional teams; the valorisation of personal relations, which is stimulated by physical proximity; and project managers’ ample participation in different functions involving NPD.

Taking Root in the Silicon Forest: High-technology Firms as Surrogate Universities in Portland, Oregon

Most case studies of successful high-technology industry regions highlight the role of research universities in fostering regional economic development. The Portland, Oregon, region managed to root a thriving high-tech industry in the absence of this critical factor. In this article, I present a case study of the evolution of Portland's high-tech industry and propose that high-tech firms can act as surrogate universities that attract and develop labor, create knowledge, and function as incubators for startups. I conclude that planners working to develop high-tech industries in regions without major research universities should attract R&D-intensive firms, maintain information on key busineses and entrepreneurial ventures, support an innovation milieu, and set realistic goals.

Segmentation and Segregation Patterns of Women-Owned High-Tech Firms in Four Metropolitan Regions in the United States

Mayer H. Segmentation and segregation patterns of women-owned high-tech firms in four metropolitan regions in the United States, Regional Studies. The number of women starting and owning a business has increased dramatically and female entrepreneurs are entering non-traditional sectors such as high technology, construction and manufacturing. This paper investigates the trends in high-tech entrepreneurship by women in four US metropolitan regions (Silicon Valley, California; Boston, Massachusetts; Washington, DC; and Portland, Oregon). The research examines the sectoral and spatial segmentation patterns of women-owned high-tech firms. Although women are entering non-traditional sectors, the research finds that women entrepreneurs tend to own businesses in female-typed high-tech sectors. In established high-tech regions like Silicon Valley and Boston, male-typed and female-typed women-owned high-tech firms differ significantly in terms of sectoral and spatial segmentation regardless of firm age. While differences between male-typed and female-typed firms are not significant at the regional level for Washington, DC, the analysis shows significant intra-metropolitan differences for the female-typed high-tech firms. The paper concludes that sectoral and spatial segmentation are powerful dynamics that shape business ownership by women in high technology.

Micro-, Small- and Medium-Sized Enterprises with High-Growth Potential in the Southern Mediterranean: Identifying Obstacles and Policy Responses. CEPS Paperbacks. January 2014

The Arab Spring, which took root in Tunisia and Egypt in the beginning of 2011 and gradually spread to other countries in the southern Mediterranean, highlighted the importance of private-sector development, job creation, improved governance and a fairer distribution of economic opportunities. The developments led to domestic and international calls for the region’s governments to implement the needed reforms to enhance business and investment conditions, modernise their economies and support the development of enterprises. Central to these demands are calls to enhance the growth prospects of micro-, small- and medium-sized enterprises (MSMEs), which represent an overwhelming majority of the region’s economic activity.
