旅游交通是旅游经济发展中重要的内容之一,通过对中国十大城市群城市旅游交通可达性、铁路交通流分布情况与旅游经济联系、总量和隶属度进行计算,借助Arcgis10.2对中国十大城市群交通空间流分布情况和旅游经济联系进行空间可视化处理,并对计算结果进行综合比较分析。研究发现:高铁使得中国十大城市群城市旅游交通可达性水平得到大幅提升,且交通流分布均衡。中国十大城市群城市可达性的提升给城市旅游经济带来了一定的积极影响。高铁网络下中国十大城市群旅游经济联系分布不均衡。  相似文献

Quasi-likelihood nonlinear models (QLNMs) are an extension of generalized linear model and include a widen class of models as special cases. This article investigates some diagnostic methods in QLNMs. An equivalency between a case-deletion model and a mean-shift outlier model in QLNM is established. Two simulation study and a real dataset are used to illustrate the proposed diagnostic methods.  相似文献

Children are central to the rhetoric supporting global climate agreements, yet they are also envisaged to play a strategic role in materialising such agreements. Along with other household actors, children are implicated in localised efforts to manage global resource sustainability. As learners in educational systems that are being redesigned to encompass messages of sustainability, children are moreover positioned as ‘agents of change’ through sustainability education. Drawing on theoretical work on children's agency and interdependence, this review calls for greater attention to the structural and relational dimensions of environmental knowledge transmission to inform sustainability education. This is presented as one move towards constructing what Middlemiss (2014) terms a more ‘socially sensitive’ model of sustainable development.  相似文献

Since 2006, one of Indonesia’s biggest corporations operating in the cement industry has been trying to build a factory at Sukolilo village in Central Java, Indonesia. The potential for of environmental damage caused by mining and the construction of this new factory is the main source of conflict between the public and the giant corporation.The focus of this research was the communication strategy adopted by women in the community to reject the construction of the cement factory in Pati, Central Java, Indonesia. This research used a qualitative method through a case study approach. Interviews, observations, and literature studies were used as data collection techniques for in this research.We found that the practices of the “Bakul Gendong” communication strategy were effective in developing women’s awareness of environmental issues based on the values they believe in. Through the women peddlers, women’s awareness of the risk of environmental damage caused by the cement factories was successfully developed. They also created female farmers’ group named “Simbar Wareh” to strengthen cooperation between them and to better-organize their resistance. The women’s movement to resist the cement factory was also conducted by building a network, meeting authorities, demonstrating, displaying traditional symbols during celebrations such as the “Agustusan” (independence day celebration) and Kartinian (women’s day) as their sites of resistance. The local government and PT. Semen Gresik tended to use technical and economical communicative approaches, while the people mainly refer to local know how PT. Semen Gresik did not use the right communication strategy to understand the conflict that arose and how to handle it, until after 10 years of trying to build a factory in Sukolilo.  相似文献

堪称伦理思想者,当有指认依据在。以梁漱溟为例,提出伦理思想的三个指认依据:一是基本稳定的形上基础;二是相对系统的伦理主张;三是较为广泛的实际影响。只有坚持论从史出,我们才有可能靠近历史人物伦理思想的历史真实和价值真实。  相似文献

The skew-generalized-normal distribution [Arellano-Valle, RB, Gómez, HW, Quintana, FA. A new class of skew-normal distributions. Comm Statist Theory Methods 2004;33(7):1465–1480] is a class of asymmetric normal distributions, which contains the normal and skew-normal distributions as special cases. The main virtues of this distribution is that it is easy to simulate from and it also supplies a genuine expectation–maximization (EM) algorithm for maximum likelihood estimation. In this paper, we extend the EM algorithm for linear regression models assuming skew-generalized-normal random errors and we develop a diagnostics analyses via local influence and generalized leverage, following Zhu and Lee's approach. This is because Cook's well-known approach would be more complicated to use to obtain measures of local influence. Finally, results obtained for a real data set are reported, illustrating the usefulness of the proposed method.  相似文献

It is known that the normal approximation is applicable for sums of non negative random variables, W, with the commonly employed couplings. In this work, we use the Stein’s method to obtain a general theorem of non uniform exponential bound on normal approximation base on monotone size bias couplings of W. Applications of the main result to give the bound on normal approximation for binomial random variable, the number of bulbs on at the terminal time in the lightbulb process, and the number of m runs are also provided.  相似文献
