Effects of Mobile Commerce on Customer Usage Intention: An Empirical Study in Viet Nam
No full textMobile commerce has been rapidly developing in the recent years and it plays an important role in many aspects. In Vietnam, there are limited studies researching mobile commerce and its impacts. Therefore, this study aimed to discover the factors that influence the intentions of Vietnamese consumers to use mobile commerce.
Based on the theoretical background, the research model and its hypotheses were tested and developed by collecting the data from a questionnaire survey. This research provides thirteen hypotheses to determine the main factors that contribute to intention to use of mobile commerce system. Based on the traditional Technology Acceptance Model (TAM), the research included more dimensions into the study including trust, cost and playfulness factors.
The results are based on the data analysis collected from 235 Vietnamese participants through a face-to-face, a paper survey and online questionnaire. The result showed that the intention to use dominantly affected the mobile commerce usage in this model. Perceived usefulness and perceived ease of use in this paper did not affect directly to intention to use, however, PU directly affected mobile commerce usage and PEOU indirectly affects intention to use through perceived playfulness. Intention to use has direct effect on perceived trust and perceived playfulness while mobile commerce usage has direct influence on perceived playfulness and perceived cost. Finally, it is hoped that this study could provide the outcomes to help further research to have a better insight into Vietnamese consumer behavior as well as business players to develop better strategies in mobile commerce market
Porin flexibility in Providencia stuartii: Cell-surface-exposed loops L5 and L7 are markers of Providencia porin OmpPst1
No full textEpidemiologically unrelated Providencia stuartii strains isolated in hospitals in the south of France were investigated for their porin sequences and profiles. Noticeable resistance to Î2-lactams was found to be associated with production of extended spectrum Î2-lactamases or AmpC overproduction, but not metallo-Î2-lactamases. At the same time, the expression level of outer membrane porins was unmodified in these isolates. The identity of the amino acid sequences of the major porin OmpPst1 was less than 90% in the tested clinical strains, whereas sequences of the second major porin OmpPst2 were found to be identical in all isolates. Sequence diversity identified in the OmpPst1 porins was mainly located in two cell-surface-exposed loops (L5 and L7): these loops were found to be responsible for 80% of the main movements of the protein. Parallel tempering MD simulations indicated possible coordinated movement of these loops that might affect the electrostatic interaction of the porin with membrane components (e.g. LPS) or with external molecules/surfaces. This suggests that such flexibility of surface-exposed domains of OmpPst1 may participate in bacterial adaptation to the environment
Maritime Avoidance Navigation, Totally Integrated System (MANTIS)
No full textThe principal goal of marine navigation is for a ship to reach a destination point whilst avoiding other ships and keeping clear of non-navigable areas, such as shallow water and land, using Maritime Avoidance Navigation, Totally Integrated System (MANTIS). The functions of MANTIS are (C4): Compilation of navigation information using Data Fusion techniques, where a generic framework is implemented that incorporates stochastic error modelling methods with advance neurofuzzy techniques. A new variant of neurofuzzy network is introduced and appropriately labelled Transparent Reactive Online Neurofuzzy (TRON) network. Co-ordination of global vessel operations is handled automatically using a Vessel Management Expert System (VMES); capable of unambiguously solving complex multiple ship encounter scenarios as part of journey planning and en route collision avoidance. The resulting guidance way-points are efficient and takes into consideration non-navigable areas, collision avoidance regulations, ship characteristics, sea conditions, and sensor measurement accuracy. Control of ship dynamics is performed by an Autopilot for navigation precision employing developed steering and speed guidance laws, and a controller. Confirmation of current and future predicament and the validation of VMES solutions are made simple using an Integrated Display. Simulation results for each aspect of MANTIS exemplify the effectiveness of the complete system at tackling all the problems identified. In particular, the VMES demonstrator software through the functionality of its Graphical User Interface (GUI) makes the validation process intuitive and simple, and instils confidence in the system capabilities.</p

Impact of Participatory Irrigation Management (PIM) to Local Communities and Environment in Hop Tien Commune, Dong Hy
No full textThis case-study is designed to support the development of the Viet Nam – Netherlands Water Partnership on Water for Food and Ecosystems. The partnership is between Viet Nam’s Ministry of Agriculture and Rural Development (MARD) and the Netherlands Ministry of Agriculture, Nature and Food Quality (LNV). IUCN has been asked to coordinate the Partnership development process, including through undertaking study that will identify strategies for the management of water resources that balance agricultural production with the maintenance of the integrity of critical ecosystems that depend on adequate water flows. The case study is being carried out in Hop Tien commune, Dong Hy district, Thai Nguyen province, Vietnam. The purpose of the case study is to identify mechanisms based on that water resources management, which are traditionally approached as single purpose management regimes, should be enhanced to become more integrated, multi-stakeholder based management systems. At the irrigation scheme level, water resources management is considered as irrigation governance and management. The integrated approach is carried out with considerations of various interests such as irrigation, domestic water supply and fishery in Hop Tien commune. On the other hand, issues of saving water, water resources protection should be paid attention in the case study to ensure sustainable water resources development in the area
