Study on the Comprehensive Tourism Development Pattern in Periphery Minority Area: A Case Study of Gannan Tibetan Autonomous Prefecture of Gansu Province,China

Abstract

The paper took the human-land relations as a basic point, and the theories of tourism industry system and sustainable development as the guidance, with Gannan Tibetan Autonomous Prefecture (Gannan) as the case study area. From microcosmic and macroscopic viewpoints, the author carried out function orientation and evaluation to the tourism industry development, and research on the comprehensive tourism industry development pattern of Gannan. Results show that the fragile ecological environment and the traditional economic growth pattern have restricted regional sustainable development, and made Gannan to become a representative of the periphery minority areas in Northwest China. Tourism development of Gannan is at the primary phase, with the characteristics of short industry chain and low economic efficiency. It is an inevitable choice to transform the way of regional economic growth and the development pattern of tourism industry from the traditional pattern to the pattern of sustainable development. Simultaneously, Gannan's natural, national and religious culture makes Gannan a broad prospect on the comprehensive tourism development. Gannan should choose the comprehensive tourism industry as its scientific pattern to realize sustainable development, promote harmonious social, economic and ecological development, alleviate the human-land contradictory, and realize dual goals in terms of ecology construction and economical development. For Gannan and the similar areas in China, studies on the sustainable development pattern of tourism have extremely important strategic sense with respect to tourism development and the sustainable development of regional economy.     

基于GO法的LNG接收站气化外输系统可靠性分析

为保障液化天然气(LNG)接收站工艺系统生产的安全,基于GO法原理,对某接收站气化外输系统进行可靠性分析。在对系统工艺流程分析的基础上建立GO图,并采用概率公式算法分别对该系统进行可靠性定性与定量分析。结果表明:GO图简单实用,能够直观准确地表征系统工艺流程。GO运算得出气化外输系统的平均工作概率为0.977 814,平均维修时间为58 h,系统可连续稳定运行107天以上。由于数据是基于保守原则确定基本事件的,因此,计算所得可靠性结果可以作为气化外输系统安全可靠性的下限。     

MANAGEMENT MODEL FOR CONTROLLING NITRATE CONTAMINATION IN THE NEW JERSEY PINE BARRENS AQUIFER1

ABSTRACT: Land use planning in rapidly developing areas can serve as an effective tool for minimizing water quality impacts on ground water supplies. A land use management model applied to Jackson Township of the New Jersey Pine Barrens was developed. The management model consisted of a simulation model for the transport of nitrates from septic tank systems through the aquifer and a multiobjective, goal programming optimization model to determine population density restrictions using 208 areawide planning population projections. Results showed that growth may have to be curtailed in several areas of Jackson Township and that current population projections over the next 30 years may result in unacceptably high nitrate concentrations downgradient of Jackson Township. The management framework provides a flexible approach to land use planning.

基于GM(1,1)模型的安全管理目标值确定方法

在事故预防中,安全目标管理是非常重要的工作之一。在确定管理目标时,由于不可能全面、真实地掌握所有信息,同时决策的信息量小,没有确定的分布规律,因此借助灰色理论建立的年伤亡次数与时间之间数值模型,可以反映安全技术措施的持续改进,安全管理的加强,安全教育工作的贯彻以及人们对安全与日俱增的要求。实例表明,采用灰理论进行预测,有以下几个优点:优于传统的以概率论和模糊数学为基础的预测方法;预测结果精度高;可以从多角度考查对象,得出的数据更能体现企业安全状况的现实规律,反映企业现阶段的安全状况。同时为制定科学、合理而可行的安全管理目标提供依据,促使企业安全管理提高到一个新水平。

Steel sharpens steel: A review of multilevel competition and competitiveness in organizations

Competition between individuals permeates people's lives as they strive for limited resources, services, and status. However, research on competition and competitiveness in organizations is limited despite its relevance to relational dynamics (e.g., rivalry), individual differences (e.g., traits and gender), social factors (e.g., competitive climate), and organizational outcomes (e.g., work performance and unethical behavior). In this article, we propose a multilevel model of competition and competitiveness that includes the individual, the group, and the situation. By providing a holistic overview of research across a broad array of disciplines, we organize the field and create a usable framework to advance knowledge of competition and competitiveness. In doing so, we identify what we know, what we still need to discover, and provide direction for future research. The article closes with an assessment of methods and measures used in studying competition. In conclusion, this review establishes a multilevel and integrative structure that incorporates individual and team competitiveness with competitive situations that prompt competitive processes and important organizational outcomes.
