Some tourists only have a slight idea of where they want to go on a holiday when planning starts. Such tourists or their travel partners are likely to look for information for making a final travel decision. As the web becomes an increasingly popular information source, tourism destination websites can play a critical role in destination choice. A rubric for comparing tourism websites put forward by Dion and Woodside (2010) is used and ideas for enhancing the rubric are introduced utilizing a growing literature. Comparisons are made for the tourism websites of Hong Kong, Shanghai, Beijing, and Taipei. Analysis involves considering websites' quality and usefulness. The study indicates that Hong Kong's site is best while Beijing has the most room for improvement. The paper concludes with implications of the research for website analysis. The discussion includes contributions to the value of criteria for websites found in the literature but not covered in an information-quality performance rubric. 相似文献

Land and water resources are two basic factors for sustaining the development of agriculture. The two are scare resources with rapid social economic development gradually, especially in Mu Us Sandy Land (MUSL) with severe desertification. Arsenic sandstone is a special rock type of MUSL with strong water holding capacity, which appropriately makes up the shortage of sand on water and fertilizer losing. Based on it, a comprehensive framework on land-water resources development was proposed including engineering treatment measures, appropriate irrigation management and farming measures after a series of experiments designed for sandy land treated with arsenic sandstone. Results of the experiments showed that both water content and fertility increased after using a 1:2 arsenic sandstone/sand ratio by mixing both together. An area of 151.3 ha arable land was newly-increased by applying the framework in Dajihan village sandy land of the MUSL, which created direct economic efficiency of 14.1 million Yuan RMB by tomato planting, and obtained 61% of water saving effect compare to untreated sand. The application of the framework in Dajihan village also got huge social-ecological efficiency such as on soil and water conservation, sand-fixing and forming high quality farmland. The framework helped to completed the process from soil synthesize to agricultural production, then to real soil, which transformed the traditional sandy land treatment to sandy land development, and was proved to be practicable and sustainable in local sandy agriculture. 相似文献

Generic budgeting systems such as PPBS and Zero-Based Budgeting (ZBB) are criticized by academics for failing to give consideration to some of the key variables affecting behaviour in budgeting endeavours. Despite this criticism, the literature has devoted little attention to modifications that can be made to make the systems more responsive to different configurations of organizational variables. This paper addresses this oversight in regard to ZBB. In particular the paper discusses ZBB within the context of two variables: (a) the degree of task uncertainty engendered by the system and (b) the character of performance measures used to evaluate units that employ ZBB. The paper argues that ZBB materially increases the degree of task uncertainty. Configured with the type of performance measures used to evaluate departments employing ZBB, the paper maintains that the increase in task uncertainty creates incentives to engage in dysfunctional behaviour, largely in the form of invalid data reporting. It is hypothesized that this problem may be responsible for the general failure of ZBB to lead to large budget re-allocations. 相似文献
