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.

Multiple Affiliations explores the autobiographical negotiations of memory and multilocality articulated by five (im)migrant women writers writing from, and being read (primarily) within, the US. Texts as diverse as Korean-American Theresa Hak Kyung Cha's Dictée (1982), Polish (Jewish)-American Eva Hoffman's Lost in Translation: Life in a New Language (1989), Chinese-American Maxine Hong Kingston's The Woman Warrior Memoirs of a Girlhood among Ghosts (1976) and China Men (1980), Caribbean/African-American Audre Lorde's Zami: A New Spelling of My Name (1982), and Pakistani-American Sara Suleri's Meatless Days (1989) highlight how various (cross-race and transnational) experiences of location, dislocation, and relocation resonate with each other and "immigrant America." Whereas the conventional immigration/assimilation paradigm assumes the resolvability of difference, (im)migration, related to the concept of diaspora, is sensitive to "different differences," related to race, class, gender, etc. Further, (im)migration points to the variability and mobility within the immigrant experience. I use the concept of diaspora, not as a metaphor, but as a lens through which to investigate subjectivities that disturb the assumed union between place, culture and identity. I further employ various exigencies of "locational feminism" to take into account shifting, unstable, postmodern identities and, at the same time, pay attention to historical and material particularities. Multiple Affiliations shows how "diasporic" dialectics - negotiations of here and there, continuity and change, roots and routes - continually shape (im)migrant subjectivities, even if the possibility of returning to the homeland is precluded and even if the experience of immigration is not firsthand. Acts of imaginative memory are called upon to re-configure diasporic identity by linking the present and the past, here and there, self and ethnic group, and with marked insistence, to rewrite history, frequendy to trouble national schemes. I propose that, far from inhabiting separate spheres, immigrant and diasporic sensibilities often overlap. / digitalisering@umu

The global flows of foreign direct investment (FDI) to Africa have increased steadily in recent years but the research on what determines the location of these investments is scarce. Research focusing on FDI flows from small and open economies such as Sweden is even more uncommon. From the locational factors found in the OLI paradigm we developed a model that was tested on a dataset of 25 African countries over the period of 2007 to 2010. The model proved inadequate in explaining the African inward FDI flows from Sweden. However, it well explains the aggregated inward FDI flows from firms around the world to Africa. Our results implies that the locational determinants derived from the OLI paradigm are inadequate in explaining Swedish FDI flows to Africa and maybe even in explaining flows from a small and open economy to developing countries. The answer to the question of what locational determinants are important for Swedish companies investing in African countries should perhaps be sought for elsewhere.

In the last three decades, depending on advances in communication technologies, there is a popular discussion that urban functions can be located independent from space. In other words, each urban function can locate to any zones of a city due to communication technology-based connections, in a so called deterritorialization. These new sprawl-based locations can be seen in the central business districts (CBD) of cities, especially by producer service functions. This thesis will investigate the validity of deterritorialization-based post-modern theoretical studies concerning recent transformation of CBDs based solely on the Western city, with reference to the distribution of such activities in Ankara and its CBD structure. Producer services can be used to test the space relations of urban functions due to their complexity and more flexible connection capacities. For this purpose, first the concepts and the fields of concepts that are based on CBDs and producer services are examined. Thereafter, these theoretical and analytical frameworks are tested in a comprehensive evaluation of urban and central growth. Ankara has been chosen as the subject of the case study due to the new locational nodes in the city and the significant threat of decline in the CBD of Kizilay, which is still the main core of city. The relations between urban space and the locational preferences of producer services in Ankara are assessed to illustrate the reterritorialization-based movements within the urban space. Finally, the implications and contributions of the study and also suggestions for possible further studies are presented as concluding remarks.

abstract: This thesis pursues a method to deregulate the electric distribution system and provide support to distributed renewable generation. A locational marginal price is used to determine prices across a distribution network in real-time. The real-time pricing may provide benefits such as a reduced electricity bill, decreased peak demand, and lower emissions. This distribution locational marginal price (D-LMP) determines the cost of electricity at each node in the electrical network. The D-LMP is comprised of the cost of energy, cost of losses, and a renewable energy premium. The renewable premium is an adjustable function to compensate `green' distributed generation. A D-LMP is derived and formulated from the PJM model, as well as several alternative formulations. The logistics and infrastructure an implementation is briefly discussed. This study also takes advantage of the D-LMP real-time pricing to implement distributed storage technology. A storage schedule optimization is developed using linear programming. Day-ahead LMPs and historical load data are used to determine a predictive optimization. A test bed is created to represent a practical electric distribution system. Historical load, solar, and LMP data are used in the test bed to create a realistic environment. A power flow and tabulation of the D-LMPs was conducted for twelve test cases. The test cases included various penetrations of solar photovoltaics (PV), system networking, and the inclusion of storage technology. Tables of the D-LMPs and network voltages are presented in this work. The final costs are summed and the basic economics are examined. The use of a D-LMP can lower costs across a system when advanced technologies are used. Storage improves system costs, decreases losses, improves system load factor, and bolsters voltage. Solar energy provides many of these same attributes at lower penetrations, but high penetrations have a detrimental effect on the system. System networking also increases these positive effects. The D-LMP has a positive impact on residential customer cost, while greatly increasing the costs for the industrial sector. The D-LMP appears to have many positive impacts on the distribution system but proper cost allocation needs further development. / Dissertation/Thesis / M.S. Electrical Engineering 2011

This chapter assesses the effects of "Eastern" EU-enlargement on the race for FDI and the policy implications. We start from the proposition that the evolving production patterns of incumbent and new member states determine the need for and the justification of location policy (LP) and FDI promotion policy (FDI-PP). On the basis of empirical production patterns, it is argued that while the specialisation outcome dominates in the short run, the convergence scenario is more likely to prevail in the medium term. Therefore, old and new EU-members will compete increasingly for the same type of FDI. How EU-enlargement per se affects the spatial distribution of inward FDI is described next. The role of FDI-PPs and LPs in an enlarged EU are discussed on the basis of the convergence outcome. Since the new economics of location competition and of FDI-promotion cast serious doubt on the economic justification and effectiveness of FDI-PP, the chapter concludes with a basic dilemma in the race for FDI: namely, the greater ineffectiveness of FDI incentives in the Single Market and fewer possibilities for differentiation of LPs. The latter is due to harmonisation pressures, which calls for innovative policy strategies by central and regional authorities. / Series: Department of Economics Working Paper Series

abstract: The subject of this thesis is distribution level load management using a pricing signal in a Smart Grid infrastructure. The Smart Grid implements advanced meters, sensory devices and near real time communication between the elements of the system, including the distribution operator and the customer. A stated objective of the Smart Grid is to use sensory information to operate the electrical power grid more efficiently and cost effectively. One potential function of the Smart Grid is energy management at the distribution level, namely at the individual customer. The Smart Grid allows control of distribution level devices, including distributed energy storage and distributed generation, in operational real time. One method of load control uses an electric energy price as a control signal. The control is achieved through customer preference as the customer allows loads to respond to a dynamic pricing signal. In this thesis, a pricing signal is used to control loads for energy management at the distribution level. The model for the energy management system is created and analyzed in the z-domain due to the envisioned discrete time implementation. Test cases are used to illustrate stability and performance by analytic calculations using Mathcad and by simulation using Matlab Simulink. The envisioned control strategy is applied to the Future Renewable Electric Energy Distribution Management (FREEDM) system. The FREEDM system implements electronic (semiconductor) controls and therefore makes the proposed energy management feasible. The pricing control strategy is demonstrated to be an effective method of performing energy management in a distribution system. It is also shown that stability and near optimal response can be achieved by controlling the parameters of the system. Addition-ally, the communication bandwidth requirements for a pricing control signal are evaluated. / Dissertation/Thesis / M.S. Electrical Engineering 2013

FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / Agglomerations of firms already are studied since 1890, with the pioneering British economist Alfred Marshall. At the time, Marshall was able to identify some of the main reasons that led firms to adopt this clustering behavior and the benefits that such an environment generated both companies and for the environment in which they settled. Since then, further studies have been conducted on the topic of new forms and structures were identified and baptized: cluster, a pole of growth, innovative environment, local productive arrangement (APL) etc.. Thinking about the benefits generated by these structures for companies and regions that host them, this work was performed. To this end, four territories of the State of Cearà were addressed: Curu Valley and AracatiaÃu, Caninde Hinterland, Hinterland and Central Inhamuns CrateÃs. We used the instrumental of locational indicators (location quotient, and the relative share Hichmann-Herfindahl index) to identify potential points of existence of these structures. Later, there was a test that could be instrumental use of factor analysis, the necessary condensing indicators into a single index, called the concentration index productive - ICP. Through the latter, it was possible to spatially locate the potential of each municipality in relation to the existence of concentration selected productive sectors: Agriculture, Fishing and aquaculture and processing industry. We noticed a significant potential existence of these structures in most of the municipalities analyzed, with the highlight of the territories Valley Curu and AracatiaÃu and Inhamuns CrateÃs. / As aglomeraÃÃes de firmas jà sÃo estudadas desde 1890, tendo como pioneiro o economista britÃnico Alfred Marshall. Na Ãpoca, Marshall conseguiu identificar alguns dos principais motivos que levavam as firmas a adotarem este comportamento de aglomeraÃÃo, bem como os benefÃcios que tal ambiente gerava tanto Ãs empresas, como para o meio em que se instalavam. Desde entÃo, novos estudos foram realizados sobre o tema e novas formas de estruturas foram identificadas e batizadas: cluster, polo de crescimento, ambiente inovador, arranjo produtivo local (APL) etc. Pensando nos benefÃcios gerados por estas estruturas para as empresas e as regiÃes que as abrigam, foi realizado este trabalho. Para tal, quatro territÃrios do Estado do Cearà foram abordados: Vale do Curu e AracatiaÃu, SertÃo de CanindÃ, SertÃo Central e Inhamuns CrateÃs. Utilizou-se o instrumental de indicadores locacionais (quociente locacional, participaÃÃo relativa e o Ãndice de Hichmann-Herfindahl) para identificar os pontos potenciais de existÃncia destas estruturas. Posteriormente, realizou-se um teste para que se pudesse utilizar o instrumental de anÃlise fatorial, necessÃrio ao condensamento dos indicadores em um Ãnico Ãndice, chamado de Ãndice de concentraÃÃo produtiva â ICP. AtravÃs deste Ãltimo, foi possÃvel localizar espacialmente o potencial de cada municÃpio em relaÃÃo à existÃncia de concentraÃÃo produtiva dos setores selecionados: AgropecuÃrio, Pesca e aqÃicultura e IndÃstria de transformaÃÃo. Percebeu-se um significativo potencial de existÃncia dessas estruturas na maior parte dos municÃpios analisados, tendo como destaque os dos territÃrios do Vale do Curu e AracatiaÃu e Inhamuns CrateÃs.

Knowledge workers (KW), as important individual agents who embody, exchange, create and exploit knowledge, contribute to regional competitiveness and growth. To attract and retain them in a region, it is necessary to have a better understanding of their fundamental spatially-related behaviors including residence, workplace, and commute choices. In this study, we depart from a perspective of knowledge typology (analytical-synthetic-symbolic knowledge base) to investigate the heterogeneity of knowledge workers' residence, workplace, and commute choices. The case study was conducted in the metropolitan region of Munich. Various types of data are integrated: structural statistical and individually-based web-survey data; individuals' actual choices and their assessment of importance for each criterion; positional and relational data. We find that symbolic Advanced-Producer-Services (APS) workers tend to reside in central areas and use public transport or active modes to commute. In contrast, synthetic high-tech workers are found in relatively peripheral areas and depend more on cars to reach their workplaces. The spatially-related choices of analytical high-tech and synthetic-APS workers are positioned in between symbolic APS-workers and synthetic high-tech workers. We reach three conclusions: Firstly, the features of the knowledge base are evident in the spatial choices of knowledge workers. Secondly, there is a consistency of characteristics between interrelated spaces surrounding residence, workplace, as well as along the commute path of knowledge workers. Lastly, while the influence of the knowledge base has to be weighed against socio-demographic factors, different groups of knowledge workers clearly display distinct choices of residential location and commute mode. These conclusions may provide insights for urban planners and policy-makers regarding the attraction and retention of knowledge workers.

The increasingly virtualized work life, brought on by increased demand on flexibility and work- life balance as well as technological development, has changed the way we work. At the same time the need for organizations to be creative in order to compete on the expanding market has grown. This is a fact that increases the need for groups to be creative through collaboration. Hence, this study investigates how collaborative creativity can be created in Mobile Multi-Locational Work Systems, from a managerial point of view. The existing theoretical body of knowledge on collaborative creativity and virtual structures, such as Mobile Multi-Locational Work Systems, points to communication as an area of key importance. When further investigating the factor of communication, two sub-areas were identified; Social Factors and Coordination. Moreover the role of leadership in collaborative creativity implies that managers have an important role in creating conditions for collaborative creativity. In order to investigate how collaborative creativity can be stimulated in Mobile Multi-Locational Work Systems, managerial perceptions of work within such a system were collected through interviews at our case company, Microsoft AB. The organization had implemented a Mobile Multi- Locational Work Systems called the New World of Work, allowing employees to work flexibly. Results imply that Mobile Multi-Locational Work Systems affect conditions for collaborative creativity in both stimulating and inhibiting manners. The system implementation appears to increase group external communication across organizational boundaries. It likely increases the amount of ideas and knowledge available, which is positive for collaborative creativity. However, handling factors related to communication, social factors and work coordination within work groups appears to be critical in facilitating collaborative creativity as they appear to be affected by the Mobile Multi-Locational Work System implementation. Results indicate that if managers allows freedom with responsibility, provides a clear framework, creates forums for social and work interaction, coaches their employees and acts as role models it is likely that they will stimulate collaborative creativity in their team.
