    Integrated Environments for Large, Complex Systems is the theme for the RICIS symposium of 1988. Distinguished professionals from industry, government, and academia have been invited to participate and present their views and experiences regarding research, education, and future directions related to this topic. Within RICIS, more than half of the research being conducted is in the area of Computer Systems and Software Engineering. The focus of this research is on the software development life-cycle for large, complex, distributed systems. Within the education and training component of RICIS, the primary emphasis has been to provide education and training for software professionals

    Since the concept of the Born Global was defined in 1993 there have been an extensive number of research papers and articles on this subject. Despite the large amount of research conducted in this area, we have found no clear evidence of papers studying the impact of the planning stage and of business model definition on the success of the internationalization process. For this study we make use of Portuguese Born Global companies and try to determine how the founders‘ initial planning, dynamic capabilities and networks contribute to shaping BGs‘ evolution and early internationalization patterns. Based on the case studies evidence we conclude that neither a detailed business plan nor external financial support are indispensable conditions for successful internationalization. Instead, the evidence clearly shows that the entrepreneur‘s networks and dynamic capabilities together with the companies‘ adaptability to market unpredictability are the necessary conditions for a Born Global to be successful at the global stage.Desde que o conceito de Born Global foi definido em 1993 um número significativo de artigos e trabalhos têm sido elaborados sobre este assunto. Apesar da enorme pesquisa efetuada sobre este tema, não encontra-mos evidências concretas de artigos ou trabalhos estudando o impacto da fase de planeamento ou o impacto da definição do modelo de negócios no sucesso da internacionalização. Na presente pesquisa utilizamos casos de Born Globals Portuguesas e tentamos determinar de que forma o planeamento inicial efetuado pelos fundadores, as suas capacidades dinâmicas e redes contribuíram na evolução da empresa Born Global e no seu processo de internacionalização. Baseando-nos nas evidências compiladas a partir dos casos estudados, concluímos que quer a existência de um plano de negócios detalhado ou o apoio financeiro externo à empresa não são condições necessárias para o sucesso no processo de internacionalização de uma Born Global. Por outro lado as evidências sugerem que as redes dos fundadores e as suas capacidades dinâmicas assim como a capacidade da empresa de se adaptar às imprevisibilidades dos mercados formam as condições necessárias para que uma empresa Born Global seja bem-sucedida no palco global

    Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2012.Cataloged from PDF version of thesis.Includes bibliographical references (p. 119-124).Crowdsourced labor markets make it possible to recruit large numbers of people to complete small tasks that are difficult to automate on computers. These marketplaces are increasingly widely used, with projections of over $1 billion being transferred between crowd employers and crowd workers by the end of 2012. While crowdsourcing enables forms of computation that artificial intelligence has not yet achieved, it also presents crowd workflow designers with a series of challenges including describing tasks, pricing tasks, identifying and rewarding worker quality, dealing with incorrect responses, and integrating human computation into traditional programming frameworks. In this dissertation, we explore the systems-building, operator design, and optimization challenges involved in building a crowd-powered workflow management system. We describe a system called Qurk that utilizes techniques from databases such as declarative workflow definition, high-latency workflow execution, and query optimization to aid crowd-powered workflow developers. We study how crowdsourcing can enhance the capabilities of traditional databases by evaluating how to implement basic database operators such as sorts and joins on datasets that could not have been processed using traditional computation frameworks. Finally, we explore the symbiotic relationship between the crowd and query optimization, enlisting crowd workers to perform selectivity estimation, a key component in optimizing complex crowd-powered workflows.by Adam Marcus.Ph.D
