The Impacts Of Network Governance On The Erformance Of Ito: A Study Of Taiwanese Firms

Information technology outsourcing (ITO) has been a topic of great interest, one that organization researchers have studied extensively. Previous studies have suggested that ITO research has expanded from one organization and bilateral partnerships to a network form of organization that links multiple organizations and spans inter-organizational boundaries. Yet, little research has been conducted on the link between network governance and ITO performance as a way to understand an organization’s ITO efforts. This study proposes a model that employs several constructs: inter-organization coordination, contractual governance and relational governance, and technological hegemony. The model explores the mediating roles of these governance mechanisms and the moderating role of technological hegemony as it influences the IT manager’s perception of the performance of ITO. Empirical testing of the model is based on a sample of 191 companies from Taiwanese industries. The results support the mediating effect of relational governance and the moderating effect of technological hegemony. The implications of these findings for ITO management are discussed

The Context of Cloud Computing/Services Adoption in Business: A Systematic Review with Activity Theory perspective

Cloud computing has been established as a prominent research topic with the rise of a ubiquitous provision of computing resources over the last decade. According to literature review, previous studies are found focusing on the technical issue mostly; however, accompanying with the cloud service developing progress, there are a wide range of applications for adopting cloud computing/services and without an overall comprehension. This study aims to proposed a conceptual framework to systematically explore the activities and elements related to cloud computing/services adoption in business. The research framework is found useful for understanding the context of cloud computing and services and the preliminary findings are helpful to further explore the related activities and relationships behind on cloud computing/services adoption in business

ICT Integrated in Higher Education: The Activities, Context and Effects

Accompanying with the development and advancement of ICT integrated in higher education, it enabled the progressive changes in centered pedagogies and practices. This study attempts to explore the context in ICT integrated education with student perspective and to propose a research model combining with readiness and activity theory to exam the effects of ICT integrated in higher education and the learning performance. 603 questionnaires were collected from the universities in Taiwan and analyzed with AMOS. The results indicate that informational-based readiness has positive effect on user’s readiness, user’s readiness and schools’ ICT support both have positive effects on ICT actual use, and ICT actual use also has positive effect on their perceived satisfaction (performance). The findings could enrich the research of ICT integrated education with different perspectives, and would be helpful to extend to the long-term development in academics and practical ICT application

Ripple effect and regional house prices dynamics in China

This paper examines the stationarity properties, the long-run equilibrium and the leadlag relationship among the regional house prices in China from December 2000 to July 2013. Unlike traditional unit-root tests, the panel seemingly unrelated regressions augmented Dickey-Fuller (SURADF) unit-root test reveals that the regional house prices in China are a mixture of I(0) and I(1) processes. There is concrete evidence in favor of the hypothesis of a long-run equilibrium relationship among all regions, except for Shanghai region, and supporting the price diffusion or ripple effect among these Chinese cities. Finally, we determine that these regional house prices exhibit uni-directional causalities running from Beijing, Chongqing, and Shenzhen to Guangzhou and Tianjin, respectively

Genomic sequence of temperate phage Smp131 of Stenotrophomonas maltophilia that has similar prophages in xanthomonads

Stenotrophomonas maltophilia is a ubiquitous Gram-negative bacterium previously named as Xanthomonas maltophilia. This organism is an important nosocomial pathogen associated with infections in immunocompromised patients. Clinical isolates of S. maltophilia are mostly resistant to multiple antibiotics and treatment of its infections is becoming problematic. Several virulent bacteriophages, but not temperate phage, of S. maltophilia have been characterized

Reconstruction of phyletic trees by global alignment of multiple metabolic networks

Background: In the last decade, a considerable amount of research has been devoted to investigating the phylogenetic properties of organisms from a systems-level perspective. Most studies have focused on the classification of organisms based on structural comparison and local alignment of metabolic pathways. In contrast, global alignment of multiple metabolic networks complements sequence-based phylogenetic analyses and provides more comprehensive information. Results: We explored the phylogenetic relationships between microorganisms through global alignment of multiple metabolic networks. The proposed approach integrates sequence homology data with topological information of metabolic networks. In general, compared to recent studies, the resulting trees reflect the living style of organisms as well as classical taxa. Moreover, for phylogenetically closely related organisms, the classification results are consistent with specific metabolic characteristics, such as the light-harvesting systems, fermentation types, and sources of electrons in photosynthesis. Conclusions: We demonstrate the usefulness of global alignment of multiple metabolic networks to infer phylogenetic relationships between species. In addition, our exhaustive analysis of microbial metabolic pathways reveals differences in metabolic features between phylogenetically closely related organisms. With the ongoing increase in the number of genomic sequences and metabolic annotations, the proposed approach will help identify phenotypic variations that may not be apparent based solely on sequence-based classification.National Institutes of Health (U.S.) (Grant GM081871

Nocturnal CPAP improves walking capacity in COPD patients with obstructive sleep apnoea

BACKGROUND: Exercise limitation is an important issue in patients with chronic obstructive pulmonary disease (COPD), and it often co-exists with obstructive sleep apnoea (overlap syndrome). This study examined the effects of nocturnal continuous positive airway pressure (CPAP) treatment on walking capacity in COPD patients with or without obstructive sleep apnoea. METHODS: Forty-four stable moderate-to-severe COPD patients were recruited and completed this study. They all underwent polysomnography, CPAP titration, accommodation, and treatment with adequate pressure. The incremental shuttle walking test was used to measure walking capacity at baseline and after two nights of CPAP treatment. Urinary catecholamine and heart rate variability were measured before and after CPAP treatment. RESULTS: After two nights of CPAP treatment, the apnoea-hypopnoea index and oxygen desaturation index significantly improved in both overlap syndrome and COPD patients, however these changes were significantly greater in the overlap syndrome than in the COPD group. Sleep architecture and autonomic dysfunction significantly improved in the overlap syndrome group but not in the COPD group. CPAP treatment was associated with an increased walking capacity from baseline from 226.4 ± 95.3 m to 288.6 ± 94.6 m (P < 0.05), and decreased urinary catecholamine levels, pre-exercise heart rate, oxygenation, and Borg scale in the overlap syndrome group. An improvement in the apnoea-hypopnoea index was an independent factor associated with the increase in walking distance (r = 0.564). CONCLUSION: Nocturnal CPAP may improve walking capacity in COPD patients with overlap syndrome. TRIAL REGISTRATION: NCT0091426
