The convergence of mobile commerce and internet technologies has promised users unprecedented convenience and greater enjoyment. Over the past few years, the development of mobile information and entertainment services (MIES) has been phenomenal. Recently, research has been conducted into ways toward better acceptance of these services by users. However, many of these studies are technical driven, without discussing important end user needs. To understand users' perception associated with mobile information and entertainment services the author extended and empirically tested a new antecedent model of Perceived Playfulness an intrinsic motivator toward technology acceptance by users, based on previous research. It has been shown that user's Perceived Playfulness toward information technologies has a direct impact on his/her subsequent use. Using the new antecedent model of Perceived Playfulness, the author argues users' Autotelic Personality, Perceived Service Quality, Perceived Technology Compatibility, their Motivation for Using and tolerance of Social Influence affect their Perceived Playfulness when interacting with MIES. A questionnaire was administered to students in business and computing schools at Auckland University of Technology. The closed-ended questions within the questionnaire were used to validate the proposed research model. The data were analyzed using Partial Least Squares. Most of the proposed hypotheses were supported, rendering several significant findings in this thesis. In this study, it has been found that individuals who are more innovative and confident about using MIES are more likely to develop a positive image toward these services. They also value services that are useful and easy to use and demonstrate high enthusiasm for more personalized mobile services. More importantly, their perceptions toward MIES can be further reinforced if their mobile phone functionalities are highly compatible with these services. Therefore, service providers should strive to create a seamless MIES experience for users. Furthermore, given that mobile phones have their own strengths and limitations, the motivation behind user's choices of various applications becomes an important issue for service providers to consider. It has been shown that the importance of service attributes vary with user's motivations of using MIES. This study therefore focuses on several important end user issues which are not well explored in the research of mobile internet services. Overall, this study contributed to existing research into user s perception toward MIES as an information technology based on his/her intrinsic motivator. Several important antecedents have been identified to influence user's Perceived Playfulness in this context. Limitations and suggestions for future studies are considered at the end of this thesis. Implications are also discussed.

This work comprises studies addressing fundamental questions of the diamond surface physics for different doping concentrations of nitrogen and boron, and how doping is reflected in the core shell analysis, valance band structure and work function values. A second aspect of the work is the controllable creation of nitrogen-vacancy (NVs) centers accompanied by comprehensive surface spectroscopy studies (XPS,UPS and MIES). Additionally, in order to increase and stabilize NV negative (NV-), which are required for quantum computing system, studies on diverse oxygen termination procedures has been executed. The efficiency of oxygen termination procedures compared and is confirmed by spectroscopy and wet contact angle (WCA) measurements. Furthermore, an alternative method of hydrogen termination of the diamond surface is proposed and compared to the traditional hydrogen plasma termination. As related side aspect, the deposition of C60 molecules on the diamond surface is performed and investigated by means of UPS and MIES spectroscopy. A distinctive experimental capability of studies is the implementation of the Metastable Impact Electron Spectroscopy (MIES) spectroscopy. This unique surface spectroscopy technique and individual instrumentation design for probing the electronic structure of the outermost surface layer, including measurement examples is introduced in this work.

In this scenario the architect Mies van der Rohe (1886-1968) turned out to be, through his textual and architectural discourse, a spokesman for the spiritual quest in architecture. Therefore this research aimed, at first, to outline the career of the architect. Secondly,it sought - through the articulation of studies of textual speechs on spirituality of Mies van der Rohe and the architectural design analysis of the Barcelona Pavilion (1929-30), designed by the architect - to understand the dimensions of the yearning for the expression of the spiritual dimension, and which were the spiritual nature decisions that could raise the architecture to the status of art. / Diversos movimentos arquitetônicos e artísticos marcaram de modo transformador a primeira metade do século XX. Neste cenário o arquiteto Mies van der Rohe (1886 1968) acabou se tornando, por meio de seus discursos, um porta-voz da "busca espiritual" na arquitetura. Diante disso o presente trabalho buscou, em primeiro lugar, traçar uma trajetória profissional do arquiteto e, em segundo lugar, buscou por meio da articulação dos estudos do discurso textual acerca da espiritualidade de Mies van der Rohe e a análise projetual do Pavilhão de Barcelona (1929-30), projetado pelo arquiteto, compreender as dimensões do anseio pela expressão da dimensão espiritual , e em que constituíam as "decisões" de ordem espiritual que poderiam elevar a arquitetura ao status da arte.
