Learning Management System Transformation

Since most of the current literature of system development and implementation are focused on large and complex systems in large corporations, there is a need to study smaller scale system implementation, upgrading, and transformation. This study focuses on small scale system transformation, namely transfer learning management system (LMS) from Blackboard to Moodle at a US university, in order find the similarity and differences between large and small scaled system implementation and transformation. The goal is to identify issues specially related to smaller scale LMS upgrades, and provide insight to IT administrators and administrators of educational institutions

Synthesis, Processing and Characterization of Polymer Derived Ceramic Nanocomposite Coating Reinforced with Carbon Nanotube Preforms

Ceramics have a number of applications as coating material due to their high hardness, wear and corrosion resistance, and the ability to withstand high temperatures. Critical to the success of these materials is the effective heat transfer through a material to allow for heat diffusion or effective cooling, which is often limited by the low thermal conductivity of many ceramic materials. To meet the challenge of improving the thermal conductivity of ceramics without lowering their performance envelope, carbon nanotubes were selected to improve the mechanical properties and thermal dispersion ability due to its excellent mechanical properties and high thermal conductivity in axial direction. However, the enhancements are far lower than expectation resulting from limited carbon nanotube content in ceramic matrix composites and the lack of alignment. These problems can be overcome if ceramic coatings are reinforced by carbon nanotubes with good dispersion and alignment. In this study, the well-dispersed and aligned carbon nanotubes preforms were achieved in the form of vertically aligned carbon nanotubes (VACNTs) and Buckypaper. Polymer derived ceramic (PDC) was selected as the matrix to fabricate carbon nanotube reinforced ceramic nanocomposites through resin curing and pyrolysis. The SEM images indicates the alignment of carbon nanotubes in the PDC nanocomposites. The mechanical and thermal properties of the PDC nanocomposites were characterized through Vickers hardness measurement and Thermogravimetric Analysis. The ideal anisotropic properties of nanocomposites were confirmed by estimating the electrical conductivity in two orthogonal directions

Do People Trust Information from Social Media?

Social media may have started with the simple notion of casually connecting friends and relatives, but from those origins, have become complex of overlapping nexus involving every sort of human activity imaginable. Users of social media have shown themselves to be a contradiction- both savvy and gullible in their consumption and transfer of information. The nature of information quality in the context of social media is mostly unstudied and consequently, mostly not understood. The quality of information moving through social media, and the social media users’ confidence in the quality of the information, are vital factors to be studied in order to gain a comprehensive understanding of such an important global phenomenon. This research investigates users’ trust in information obtained from social media

Enterprise business ecological strategic capabilities and enterprise group ecosystem health: an analysis based on the Sichuan Port and Channel Development Enterprise Group

An enterprise group is a complex group of independent enterprises that are linked by a number of formal or informal relationships. Regarding enterprise group as a kind of business ecosystem, this dissertation explores the relationship between enterprise’s business ecological strategic capabilities and enterprise group’s ecosystem health based on Sichuan Port and Channel Development Enterprise Group, adopting business ecological perspective, enterprise capability theory and social network analysis theory. From ecological perspective, enterprises within a business ecosystem will be playing different roles. Therefore each of them will be having different basic strategic capabilities corresponding to its specific role, which will not only be influencing the enterprise’s own performance, but also stimulate the system’s ecosystem health. This dissertation used role-capabilities matching model to measure enterprise’s business ecological strategic capabilities, and construct a regression model of the enterprise’s role-capabilities matching rate and performance. We demonstrated and clarified enterprises business ecological strategic capabilities’ influence to the enterprise group’s ecosystem health. We proposed relevant theoretical hypotheses of the relationship between enterprise’s rolecapabilities matching rate and enterprise group’s ecosystem health, the every dimension of business ecological strategic capabilities of niche player and enterprise group’s ecosystem health, and verify our hypotheses using data from questionnaires responded by the top management in Sichuan Port and Channel Development Enterprise Group’ s enterprises. Main conclusions drawn were that 1) the higher the enterprise’s role-capabilities matching rate was, the better the enterprise group’s ecosystem health would be; 2) The niche player’s business ecological strategic capabilities of every dimensions have a positive impact on the enterprise group’s ecosystem health, yet different dimensions of business ecological strategic capabilities have different mechanisms in impacting such performance. Our findings have practical significance in enterprise group governance.Um grupo empresarial é um grupo complexo de empresas independentes ligadas por várias relações formais e informais. Considerando o grupo empresarial como um tipo de ecossistema empresarial, com base no Grupo Empresarial do Desenvolvimento do Canal e do Porto de Sichuan, esta dissertação explora a relação entre capacidades estratégicas ecológicas de negócios da empresa e a saúde do ecossistema do grupo empresarial, adotando a perspetiva ecológica de negócios, teoria de capacidade empresarial e teoria de análise de redes sociais. Do ponto de vista ecológico, as empresas num ecossistema de negócios desempenharão papéis diferentes. Por isso, cada um deles terá diferentes capacidades estratégias básicas, correspondentes ao seu papel específico, que não apenas influenciarão o desempenho da própria empresa, mas também estimularão a saúde do ecossistema. Esta dissertação usa o modelo de função-capacidade para medir as capacidades estratégicas ecológicas de negócios da empresa e constrói um modelo de regressão sobre a taxa de correspondência de função-capacidade da empresa e o seu desempenho. Demonstrámos e esclarecemos a influência das capacidades estratégicas ecológicas de negócio da empresa na saúde do ecossistema do grupo empresarial. Baseado na revisão extensiva de literatura na área de perspetiva ecológica de negócios, de teoria de capacidade empresarial e de teoria de análise de redes sociais, propomos hipóteses relevantes à relação entre a taxa de correspondência de função-capacidade da empresa e a saúde do ecossistema do grupo empresarial, entre cada dimensão das capacidades estratégias ecológicas do jogador de nicho e a saúde do ecossistema do grupo empresarial. Pesquisamos na relação entre empresas no ecossistema do grupo empresarial, as capacidades estratégicas ecológicas de empresa, a saúde do ecossistema do grupo empresarial, com base nos questionários feitos pela administração sénior das empresas do Grupo Empresarial do Desenvolvimento do Canal e do Porto de Sichuan e verificamos as nossas hipóteses através dos dados obtidos a partir dos questionários. As conclusões são: 1) mais alta a taxa de correspondência de função-capacidade da empresa, melhor saúde do ecossistema do grupo empresarial; 2) as capacidades estratégicas ecológicas de negócios de cada um dos participantes de cada dimensão têm um impacto positivo na saúde do ecossistema do grupo empresarial, mas diferentes dimensões das capacidades estratégicas ecológicas de negócios têm mecanismos diferentes para influenciar esse desempenho. Os nossos resultados não apenas contribuem para a construção do ecossistema de negócios dentro do grupo empresarial, mas também têm significado teórico para estudos quantitativos sobre micro-questões relacionadas ao ecossistema de negócios
