Then it analyzes the significance of CBET development in nature reserve (NR). The authors think that community participation is the evitable choice of nature reserve′s conservation and development. CBET, as the self-improved model of ecotourism, can promote tourism community sustainable development. Based on the stakeholder analysis of CBET in NRs, this paper addresses the reality, especially the problem of CBET development in NRs of China. In order to develop CBET in NRs of China, this paper takes some suggestions to promote the community participation: 1)gradual political empowerment, 2) deep level economic incentive, 3) widespread educational support, 4) impartial distribution of community benefits, and 5) stakeholders cooperation.展开更多

Although its importance is well-established, iterative usability testing is often forgone. Further, serious games present unique challenges that they must be usable, enjoyable, and effective. It is necessary that the game＇s design is evaluated at several stages during development to ensure that all of these objectives are met. A model for incorporating usability testing into development that addresses these three elements is presented, along with guidelines for implementation focused specifically on small serious games development teams. By applying this model to development should ensure that developers are able to efficiently produce more effective serious games.展开更多

We have reconstructed the two-dimensional topology of the magnetic field structure observed by C1 using Grad-Shafranov reconstruction method. Results show that CI passed through part of a plasmoid, which compressed the lobe magnetic field and formed a TCR. The size of the whole plas- moid structure in X direction is estimated to be about 3 Re. Furthermore, using multi-spacecraft observations, we have found some detailed information about this structure. First, C1 observed bi-streaming electron components, which supports our sug- gestion that the spacecraft passed through closed field lines. Second, a small magnetic field perturbation within this plasmoid accompanied by slight decrease in electron flux suggests that a flux rope core might exist at the center of the plasmoid.展开更多
