Open innovation (OI) is currently being applied as a new mode for firms to utilise both internal and external resources for R&D and new product developments. Investigating the impact of OI on China's high-tech firms is becoming increasingly important. Under the guidance of China's national innovation policy and the rise of innovation in high-tech industries, OI is regarded as having a positive impact on the competitiveness of Chinese firms and as bringing a significant innovation outcome. By utilising and integrating external knowledge and resources, OI can promote high-tech firms' R&D development in China's current transitional environment. A key objective of this thesis is to examine the overall relationship between locational factors, ambidexterity in OI and innovation performance given absorptive capacity (ACAP). The thesis reviews the current literature regarding OI, ambidexterity in OI, the cluster effect and ACAP and then integrates these lenses to build links for constructing a new model of the research. This includes the relationships between locational factors, ambidexterity in OI and innovation performance. It also examines the moderating effect of ACAP and, more importantly, the mediation effect of ambidexterity in OI on the relationship between locational factors and innovation performance. The findings of the thesis reveal that locational factors positively affect ambidexterity in OI, while ACAP positively moderates the relationship between the two factors. In addition, ambidexterity in OI - an optimal combination of inbound and outbound OI - can significantly influence innovation performance and is crucial to the ambidextrous conduction of firms. ACAP also positively moderates the relationship between ambidexterity in OI and innovation performance. Finally, ambidexterity in OI can mediate the relationship between locational factors and innovation performance, and ACAP moderates the overall relationship between locational factors, ambidexterity in OI and innovation performance. This thesis makes a number of contributions to the existing OI literature. First, building on the cluster perspective, the thesis contributes to the literature on OI by recognising the influence of locational factors on the balance in OI. The examination of ACAP also contributes to the literature by highlighting the contingent value of ACAP on the relationship between locational factors and the balance in OI. Second, the thesis contributes to the OI literature by bringing a greater conceptual clarity to the view of balance. A more balanced portfolio can bring better innovation performance than those that are less balanced. The thesis also enriches the knowledge in the relationship between the balance in OI and innovation performance, which demonstrates the moderating effect of ACAP on this relationship. Third, the study conceptualises the balance in OI that mediates the relationship between locational factors and innovation performance. It is a key contribution to the existing OI literature by advancing our understanding of the overall relationship among locational factors, the balance in OI and innovation performance.

Esta tese visa demonstrar a aplicação do padrão ODP (Open Distributed System) no desenvolvimento de sistemas distribuídos e abertos aplicados em automação. Para atingir este objetivo define-se uma estratégia cujos elementos básicos são: a metodologia ODP e o experimento ODP. A metodologia suporta o padrão ODP, numa estrutura sistemática e o experimento, aplica-se num projeto, para observar o comportamento do processo de aplicabilidade. A metodologia ODP está composta dos conceitos, procedimentos e modelos, propostos pelo padrão ODP; das técnicas e conceitos da orientação a objetos e da estrutura de um modelo de sistema aberto de automação (SAA), constituindo uma estrutura coerente e gerenciável, de aplicação prática nos projetos de sistemas abertos em automação. No experimento ODP, a metodologia é aplicada no desenvolvimento de um sistema de automoção, cujo escopo são os projetos dos grandes empreendimentos, que utilizam em seu processo de desenvolvimento a engenharia simultânea. O resultado desta automação será caracterizada pela obtenção de um sistema distribuído, aberto e configurado como ambiente cooperativo (Groupware) de projeto. Finalmente, os resultados do experimento serão comparados com outros tipos de metodologias que não utilizam o ODP, para poder concluir sobre a utilização do padrão ODP nos projetos de sistemas de automação. / This thesis purposes to demonstrate the applicability of the open distributed processing standard, in the development of the open distributed system applied in the automation. To achieve this objective a strategy is defined, whose basic elements are the ODP methodology and the ODP experiment. The methodology supports the ODP standard in a systematic structure and the experiment applies it in one project, to observe the behavior of the applicability process. The ODP methodology is composed by concepts, procedures and models, proposed by the ODP standard; by techniques and concepts of the objects oriented, and the structure of an open automation system model (OAS), establishing an manageable and coherent structure. In the ODP experiment, this methodology is applied in the development of an automation system which scope is the large enterprise projects that use in his development process the concurrent engineering. The result of this automation will be characterized by the Open Distributed System and will be configured as a project cooperative environment (Groupware). Finally, the experiment results will be compared with other methodologies that don\'t use ODP, to obtain conclusions about the use of the ODP standard in the automation system projects.

A crescente demanda por analises rápidas, simples e eco-fiendly tem feito da busca pela miniaturização e automatização dos procedimentos de preparo de amostra uma necessidade permanente na academia e na indústria. Atualmente, embora existam diversas técnicas miniaturizadas de preparo de amostra, estas ainda são utilizadas de forma manual na maioria das situações, pois o acesso às possibilidades de automatização em muitos laboratórios de química é ainda bastante limitado. Afortunadamente, as plataformas de robótica Open-Source estão se tornado uma alternativa interessante no desenvolvimento lab made de todo tipo de instrumentos e sistemas automatizados. Esta tese apresenta três exemplos de desenvolvimento no laboratóriode sistemas robotizados para a automatização de técnicas miniaturizadas de preparo de amostras. Num primeiro estudo, foi projetado, construído e programado um robô cartesiano capaz de operar simultaneamente seis microsseringas de extração. Este sistema foi posto à prova na automatização da microextração por sorvente empacotado (MEPS) e validado na extração de HPAs em amostras de esgoto sanitário, demostrando alta precisão, exatidão e frequência de análise. Um segundo robô cartesiano, equipado com uma única unidade de extração, foi projetado, construído e programado para conseguir pela primeira vez a integração on-line da microextração em fase liquida (LPME) com a análise mediante cromatografia líquida. Este sistema possibilitou o desenvolvimento de um método para determinação de triazinas, com tempo de total de análise de 10 minutos, incluindo o preparo da amostra e a separação/detecção dos analitos. Finalmente, por integração de técnicas em fluxo, ferramentas de robótica Open-Source e impressão 3D, a microextração líquido-líquido dispersiva baseada na solidificação da fase orgânica (DLLME-SFO) foi completamente automatizada pela primeira vez. O sistema assim desenvolvido foi validado no desenvolvimento de um método para a determinação de parabenos em produtos de cuidado pessoal, águas, urina e saliva, demostrando de esta forma, o grande potencial das tecnologias modernas no desenvolvimento de novos, versáteis e eficientes sistemas automatizados nos laboratórios de química. / The growing demand for rapid, simple and eco-friendly analyzes has made the search for miniaturization and automation of sample preparation procedures a permanent necessity. Although, nowadays there are a number of miniaturized sample preparation techniques, they are used manually in most situations. The access to automation tools is limited yet, in many chemistry laboratories. Fortunately, Open-Source robotics platforms have become an interesting alternative in the lab-made development lab made instruments and automated systems. This thesis presents three examples of laboratory development of robotic systems for the automation of miniaturized sample preparation techniques. In a first study, a cartesian robot capable of simultaneously operating six extraction microsystems was designed, constructed and programmed. This system was tested in the automation of microextraction by packaged sorbent (MEPS) and validated in the extraction of HPAs in sanitary sewage samples, demonstrating high accuracy and throughput analysis. A second cartesian robot, equipped with a single extraction unit, was designed, constructed and programmed to accomplish for the first time the online integration of the liquid phase microextraction (LPME) and the liquid chromatography analysis. This system allowed the development of a method for the determination of triazines, with an analysis time of 10 minutes, including sample preparation and separation / detection of the analytes. Finally, by integrating flow techniques, Open-Source robotics tools and 3D printing, dispersive liquid-liquid microextraction based on solidification of floating organic drop (DLLME-SFO) was completely automated for the first time. The developed system was validated in the development of a method for the determination of parabens in personal care products, water, urine and saliva, thus demonstrating the great potential of modern technologies in the development of new, versatile and efficient automated systems in chemistry laboratories.

O objetivo deste trabalho é estudar o processo de adoção do Software Livre na Universidade de São Paulo. É de especial interesse o estudo dos aspectos culturais e organizacionais que contribuíram para a adoção do Software Livre entre os administradores de sistemas. O estudo de adoção, não se limitou à adoção individual, mas se estendeu à adoção organizacional uma vez que a adoção de inovações tecnológicas em organizações difere de modo especial da adoção individual. A adoção organizacional aborda aspectos como a extensão do uso da inovação e, o quão profundamente o uso da tecnologia altera processos, estruturas e cultura organizacional. O fenômeno de adoção na Universidade revela-se particularmente importante por ter se tratado da adoção de uma nova tecnologia, em grande escala e bem-sucedida. Esta pesquisa estuda quais são os fatores condicionantes e os que favoreceram a adoção da nova tecnologia, bem como o contexto social e cultural desta adoção em diferentes Unidades da USP. / The objective of this work is to study the adoption of Free Software in the University of São Paulo. It is of special interest the study of the cultural and organizational aspects that contributed to the adoption of the Free Software among the systems administrators. The adoption study, was not limited to the individual adoption, but it extended to the organizational adoption once the adoption of technological innovations in organizations differs in special ways from the individual adoption. The organizational adoption examines aspects as the extension of the use of the innovation and, how deeply the use of the technology affects processes, structures and organizational culture. The adoption phenomenon in the University is particularly important for having it been a voluntary adoption of a new technology, in great scale and well succeeded. This research studies which factors restricted or favored the adoption of the new technology, as well as the social and cultural context of this adoption in different Units of USP

The purpose of this study was to ascertain whether the adoption of Open Educational Resources had a significant effect on student learning outcomes in seven courses taught at seven post-secondary institutions. The use of open educational resources (OER) is increasing in the United States. Initiatives focusing on expanding the use of OER as a replacement for traditional textbooks at the post-secondary level include OpenStax, Project Kaleidoscope, Open Course Library, and others. While researchers have begun to explore OER, few have sought to evaluate the quality of OER as a function of student academic success. In this dissertation, I examined measures of student success in seven courses at seven different early-adopters of Project Kaleidoscope where faculty members chose to adopt OER to replace traditional textbooks. The sample for this study consisted of students using open textbooks in courses at seven Project Kaleidoscope post-secondary institutions, as well as a control group of students at those same institutions who used traditional textbooks in sections of the same courses. I used an ex-post-facto quasi-experimental design, in which I compared students using OER to students using traditional textbooks in comparable courses. In order to control for the threat of selection bias, I used propensity score matching (PSM) to match treatment and control groups on a set of demographic variables. After creating matched treatment and control groups, I used multiple regression and logistic regression to examine whether textbook selection predicts a measurable difference in student achievement after accounting for relevant covariates. I found that students using open textbooks earned, on average, lower grades than students who used traditional textbooks, after controlling for student-level and course-level covariates. Further analysis revealed that this negative differential was isolated to students in business and psychology classes. I also found that students who used open textbooks enrolled in more credits than students using traditional textbooks, controlling for relevant covariates. Because of the finding of a variation in textbook effect from course to course, future studies may seek to understand the effects of particular OER adoption instances rather than the global effect of OER adoption.

This thesis deals with open-source software QGIS.It is a free and multiplatform geographical information system (GIS) which is distributed under the general public license (GNU). In the framework of this thesis, a teaching course was created, various types of analyses that the system allows. A set of model exercises is intended to represent a integrated course in the Quantum GIS, which will enable the user to become acquainted with this SW and will be useful in teaching, but also in the practice of public administration, especially in regional development. For this reason, the author realized a survey in the municipalities of the South Bohemian Region concerning the introduction of GIS, awareness of QGIS software, possible interest in the course and topics which the municipalities would like to dedicate to. The requirements of the municipalities have been implemented into individual exercises. The course is available in e-learning in the Moodle system on the link: https://moodle.ef.jcu.cz/course/view.php?id=2683, but also in the form of a comprehensive document which is annexed to this work.

<p>Open access to scientific literature on Internet is a concept which is supposed to change librarians' work. The aim of the thesis was to examine librarians' perception of Open access. A questionnaire survey was conducted among librarians at libraries with specialisation in technique, natural sciences, medicine and pharmacy in Sweden. Even though Open access can be regarded as an alarming for librarians' work, the results of the survey showed that the future of the librarians' profession can be positive if they flexibly adopt their work routines according to changes in publication forms and library users' needs.</p>
