This research focuses on developing a framework for Worldwide Interoperability for Microwave Access (WiMax) technology adoption by Small and Medium Enterprises (SMEs) in the Kingdom of Saudi Arabia (KSA). WiMax has emerged as a technology to overcome the limitations of traditional and existing broadband technologies and support a great number of organisations and consumers/citizens in providing a higher speed over substantial distances i.e. in areas that are difficult for wired infrastructure to reach. Despite all the interest in the types of broadband adoption as demonstrated by SMEs in several countries, there seems to be slow progress and lack of information supporting the decision making process for WiMax technology adoption by SMEs specifically in the context of KSA. This may illustrate that SMEs adopt WiMax technology solutions at a slower pace and make them characterised as laggards in terms of new technologies adoption. This research takes into consideration this literature gap and makes a step forward and investigates on WiMax technology adoption by SMEs in KSA with an organisational cultural view, vendors’ commercialisation strategies and government policies by analysing the normative literature related to this research. The data collection of this study was carried out in two phases including quantitative and qualitative approaches. The first phase of the research provided results indicated that, the Saudi SMEs who participated in this research are strongly dominated by clan culture and adhocracy culture. These cultures also have a positive impact on the Internet technologies adoption such as WiMax by SMEs. It is found that, the combination of clan and adhocracy cultures in Saudi SMEs is making them more likely to adopt latest Internet technologies. In the second phase, the results showed a wide difference in views among SMEs, WiMax vendors and government agencies involved in WiMax technology diffusion to SMEs in Saudi Arabia. Although WiMax technology started as an innovation that has the potential to be disruptive and could replace the widely diffused fixed wire line Internet connection, the research findings showed an interesting deviation from this path. In particular, the WiMax technology market analysis in Saudi Arabia highlighted the vendors’ tendency to treat WiMax technology as a sustaining innovation. Research findings also indicated that, the Saudi government provided funds for Information and Communications Technology‘s diffusion in the country. However, the level of awareness displayed by SMEs is persistently low. Knowledge deployment, mobilisation, innovation directive and subsidy have been emphasised by SMEs as the most important government interventions that might have an impact on WiMax adoption by them. Finally, further important issues have been uncovered by the research such as taxation, experience exchange, herd culture/bandwagon, consumer right protection and customer service in relation to the adoption of WiMax by SMEs. The perceived future prospect of these additional issues has been considered as an influence on adoption of WiMax technology by SMEs. The findings of this research can be useful to guide analysts and researchers in determining critical aspects of the complex issues involved in technologies adoption, and lead to suggestions for further valid research.

[pt] A descentralização é vista como uma das possíveis formas de melhorar a provisão do serviço público. Todavia, os resultados de uma descentralização dependem do contexto local e da forma de implementação. Esta pesquisa investiga um programa que promove a autonomia escolar no Brasil. O Programa Dinheiro Direto na Escola recursos a serem administrados pela escola tendo em vista a melhoria da infraestrutura escolar e o aumento da participação da comunidade na escola. Os recursos são administrados pelo conselho escolar constituído por membros da comunidade. Considerando regras não-lineares deste programa, explora-se dois diferentes aspectos deste programa em duas amostras diferentes de escolas. A principal contribuição deste estudo é separar o efeito de introduzir o conselho escolar na administração dos recursos do efeito de mais recursos. Esta análise é realizada para escolas pequenas em ambiente rural. Os resultados apontam que a administração dos recursos pelo conselho escolar melhora a infraestrutura da escola e também eleva o desempenho escolar. Também explora-se como o contexto local afeta este resultado. Apesar da melhoria em infraestrutura ser generalizada entre as escolas, o aumento do desempenho dos alunos só ocorreu em escolas localizadas em comunidades mais escolarizadas. A outra contribuição relevante desta pesquisa é a investigação do efeito de mais recursos em escolas urbanas. Os resultados sugerem que o aumento de recursos administrados pelo conselho escolar não elevam a participação dos pais na escola. Todavia, estes recursos extras contribuem para uma melhoria dos equipamentos existentes na escola. Tais recursos são investidos mais em equipamentos do que em infraestrutura física. Também o contexto local afeta este resultado. Quanto maior a educação da mãe e o engajamento prévio da comunidade, maiores são as melhorias que beneficiam diretamente o aluno. / [en] Decentralization to lower levels of government is considered to improve public service provision. Nonetheless, decentralization outcomes are context and design dependent. This research investigates a school decentralization program that devolves authority to the school level in Brazil. The Direct Cash to School Program transfers cash direct to school management in order to improve school infrastructure and to increase community participation at school. The autonomous budget is managed by a school council constituted with community members. Considering non-linear rules in the Direct Cash to School Program, we explore two different aspects of this program within different school samples. Our main contribution is to disentangle the effects of having a school council to manage autonomous resources from the effects of additional funding. This analysis is essentially limited to small rural schools and our findings indicate that school council resource management improve school infrastructure and slightly enhance student performance. We also explore how local community educational level affects this result. Although infrastructure upgrading was generalized, investments directly benefiting students and improvement on student performance were restricted to schools with more educated community. The other relevant contribution is the investigation of whether additional locally managed resources improve school quality in an urban setting. Our findings suggest that increasing the resources under school council control do not increase overall parent participation at school. We also obtained that additional resources improve school equipment quality instead of physical infrastructure. In addition, we also consider how different local characteristics affect these outcomes. The higher the mothers education and the higher the community engagement at school, the greater the investment that directly benefit the students.

This thesis is examining the barriers that exists in the implementation of the Swedish governments broadband policy. It examines eleven municipalities in the Swedish county Östergötland and how they handle the implementation of the broadband policy. It answers three questions, what barriers exist, how do they handle them, and why do different municipalities handle barriers differently. To answer the questions, interviews with people who are in charge or knows the most about the implementation process in each municipality were conducted. There answers were analyst with an implementation analysis with focus on internal and external factors that can impact the implementation process. The answer to the thesis first question was that two types of barriers were most prominent in the implementation process, economical and collaborative barriers. In the two barriers the internal and external factors were analysed with an analysis model that provided the tools to answer the thesis second and third questions.The conclusions of the thesis are that the two most prominent barriers in the implementation process of the Swedish broadband policy are economical and collaborative barriers. The municipalities handle these barriers differently and that mainly depends on the municipalities different approach to how they can or if they want to handle the barriers.

A maior parte do ruído de aeronaves é advinda dos motores. Como houve grande avanço no controle do ruído tonal, atualmente grande parte do esforço se dá para redução do ruído de banda larga, que é menos compreendido. O ruído de banda larga é gerado pela interação entre um escoamento turbulento e uma superfície, como por exemplo, a turbulência ingerida interagindo com o rotor, o escoamento na ponta das pás, entre outros. Apesar das diversas fontes citadas, sabe-se que a principal fonte de ruído de banda larga em tal tipo de motor é a interação da esteira turbulenta do rotor com as aletas da estatora. Assim, o presente estudo manterá seu enfoque apenas em tal causa. O objetivo deste então é o desenvolvimento de um modelo capaz de previsão do ruído de banda larga pela interação da esteira turbulenta causada pelo rotor, interagindo com as aletas da estatora, bem como o entendimento da propagação do ruído em duto. A primeira abordagem em relação a tal tipo de ruído é através da previsão do ruído gerado. Para previsão de ruído podem ser utilizados métodos analíticos, numéricos, ou empíricos, cada qual com suas vantagens e penalizações. Para tal, foi utilizado um método semi-analítico, em tais métodos utiliza-se simulação numérica para previsão da característica da turbulência e uma teoria analítica para a geração e propagação do ruído no duto. A principal motivação para o método semi-analítico é sua vantagem em relação aos métodos numéricos que demandam custo computacional extremamente alto e vantagem em relação a métodos analíticos que necessitariam uma demasiada simplificação geométrica. Dessa maneira, utilizou-se a geometria do ANCF, uma plataforma de ensaios desenvolvida pela NASA, onde havia geometria e resultados divulgados, tornando possível a verificação dos resultados obtidos. Os resultados mostram que as tendências capturadas são condizentes com o esperado, e então com um tempo relativamente baixo, de maneira prática, é possível a previsão do ruído de interação e sua propagação em dutos nos motores turbofans. / The major noise source in aircraft is the engine. Since tonal noise control is well developed, the current effort concentrates on broadband noise reduction, which is less understood. The broadband noise is generated when a turbulent flow interacts with a surface as, for example, rotor blade tip flow, boundary layer and the rotor interaction. Although there are different sources of broadband noise it is known that the major broadband source in turbofan engine is the rotor turbulent wake interacting with the stator vanes. This study is focused in that source of noise and the goal is to develop a model capable of predicting the rotor/stator interaction noise as well as in duct noise propagation. Noise prediction can be carried out by analytical, numerical or empirical methods, each one with advantages and disadvantages. In the present work the semi-analytical method was used. Turbulence characteristics were estimated by a numerical method and the noise generation and duct propagation was estimated by an analytical method. The biggest advantage comparing with the numerical methods is that this method is less time consuming. A purely analytical method would require excessive geometric simplification. The ANCF, a rig developed by NASA was used as basis for the simulations, since its geometry and noise data are available. The results show that the correct trends are consistently captured. So it is concluded that it is possible to predict the broadband noise and its propagation in turbofans engines with a practical and low cost method.
