No. of bitstreams: 1 Rogerio Luciano de Sousa.pdf: 1314231 bytes, checksum: 2cff9d3364a609064bd92f7dc208a856 (MD5) Previous issue date: 2017-07-25 / Technological changes, on the one hand, bring economic benefits to organizations such as increased productivity and efficiency, on the other hand, can produce human and social problems with possible consequences to the mental health of the worker. Internet addiction is also a problem associated with information and communication technologies, as well as the stress resulting from the excessive use of information and communication technology known as techno-stress. This study analyzed the effects of Internet leadership and addiction on techno-stress. The research is based on a quantitative research approach with a single cross-section. The data were analyzed through 379 questionnaires answered by information technology professional’s users. For the hypothesis tests of the study, the analysis of structural equations was performed and satisfactory measures were presented for the constructs investigated and the proposed research model. The results indicate that leadership styles influence positively the techno-stress and internet addiction can act as moderator of these relationships. The study shows that laissez-faire leadership is the style of leadership that most influences techno-stress, when compared to transformational and transactional leadership. It can be argued, therefore, that the moderation effects of Internet addiction are different in the forms studied from the relationships of leadership styles to techno-stress. / As mudanças tecnológicas, por um lado, trazem benefícios econômicos para as organizações como maior produtividade e eficiência, por outro lado, podem produzir problemas humanos e sociais com possíveis consequências à saúde mental do trabalhador. O vício em internet também é um problema associado às tecnologias de informação e comunicação, assim como o estresse resultante do uso excessivo da tecnologia de informação e comunicação conhecido como tecnoestresse. Este estudo analisou os efeitos da liderança e do vício em internet no tecnoestresse. A pesquisa fundamenta-se em uma abordagem de investigação quantitativa com corte transversal único. Os dados foram analisados por meio de 379 questionários respondidos por profissionais usuários de tecnologia de informação. Para os testes de hipóteses do estudo, foi realizada a análise de equações estruturais e apresentadas medidas satisfatórias para os construtos investigados e o modelo de pesquisa proposto. Os resultados indicam que os estilos de liderança influenciam de forma positiva o tecnoestresse e o vício em internet pode atuar como moderador dessas relações. O estudo evidencia que a liderança laissez-faire é o estilo de liderança que mais influência o tecnoestresse, quando comparada com as lideranças transformacional e transacional. Pode-se afirmar, com isso, que os efeitos de moderação do vício em internet são diferentes nas formas estudadas dos relacionamentos dos estilos de liderança com o tecnoestresse.

聚醯亞胺薄膜用於軟性電路板市場從2006年起，由於競爭者眾多，整個產業環境變得十分嚴苛，事業屬性從獨佔性變成競爭十分激烈的寡佔性市場。此篇論文通過產業的總體環境分析及產業分析來對軟板市場進行區隔，並針對不同目標市場擬定行銷策略，將產品重新定位來滿足不同目標市場的需求，以期達到杜邦公司聚醯亞胺薄膜產品在軟性電路板市場的永續成長。 從含有產品價格因素在內的問卷調查中找到產業鏈中最有議價能力廠商的最重要需求及預估用量，進而做為公司開發下一世代聚醯亞胺薄膜產品的依據。 / Start from 2006, Polyimide films industry has become very competitive in flexible printed circuits applications. The polyimide film industry has transformed from monopoly to oligopoly, major players in flexible printed circuits market are DuPont, Kaneka, SKC-Kolon and Taimide companies. After analyzing the political, economics, social, technical and industrial trends, The FPC industry has been re-segmented into two segments – Basic market and Niche market. With different strategies been developed for different markets, we re-position our different type of Kapton® polyimide films for different markets and developed an executable marketing plan which will be test in selected customers. Through price included questionarries, we also found the key industrial decision makers’ unmet needs, price expectation and potential volume. Base on the findings, we are able to develop the next generation polyimide films to satisfy customers.
