美国国家公园建设过程中,以国家为主导,注重国家意识,定位服务功能,体现其教育理念,并在此过程中将管理和利用模式由开始的保护转变为现在的保护与利用并行,为全世界提供了一个成功的模板。但在其100年的发展过程中,环境的破坏,原住民权利的漠视,游客管理的混乱,是其曾遇到或正在面临的问题。建议我国在进行国家公园建设时,应扬长避短,突出国家名义,强调社区参与和游客管理先行,并注重国家公园的公益性和教育功能。  相似文献

On 18 December 2015, the spatial planning bill was finally passed by the Legislative Yuan in Taiwan. That was a special moment for planning community and authority since they had anticipated this moment for more than two decades. However, this is not the end of the story. On the contrary, the battle between the economic development promoters and environmental conservation supporters just starts. The Act introduces several new changes to secure its goal of nationwide sustainable development, but the introduction also raises some tensions. This article reviews the tensions and their socio-political context, and gives some suggestions to the Taiwanese government.  相似文献

Despite the continuous asymmetrical power relations between the Global North and South, the “global race for talent” is no longer a privilege enjoyed only by developed countries. Comparative analysis of policy content and effectiveness has attracted increasing interest. The examination of policy initiatives resulting in return migration of highly‐skilled migrants from the Global North to the Global South, however, remains inadequate. In this article, we provide a comparative analysis of policies targeting high‐level Chinese and Indian professionals including full‐time returnees. Two key differences in policy instruments and outcomes in the two countries are identified and they have implications for migration policies in other countries in the Global South and North.  相似文献

An oriented graph \(G^\sigma \) is a digraph without loops or multiple arcs whose underlying graph is G. Let \(S\left( G^\sigma \right) \) be the skew-adjacency matrix of \(G^\sigma \) and \(\alpha (G)\) be the independence number of G. The rank of \(S(G^\sigma )\) is called the skew-rank of \(G^\sigma \), denoted by \(sr(G^\sigma )\). Wong et al. (Eur J Comb 54:76–86, 2016) studied the relationship between the skew-rank of an oriented graph and the rank of its underlying graph. In this paper, the correlation involving the skew-rank, the independence number, and some other parameters are considered. First we show that \(sr(G^\sigma )+2\alpha (G)\geqslant 2|V_G|-2d(G)\), where \(|V_G|\) is the order of G and d(G) is the dimension of cycle space of G. We also obtain sharp lower bounds for \(sr(G^\sigma )+\alpha (G),\, sr(G^\sigma )-\alpha (G)\), \(sr(G^\sigma )/\alpha (G)\) and characterize all corresponding extremal graphs.  相似文献

In this work we investigate the online over-list MapReduce processing problem on two identical parallel machines, aiming at minimizing the makespan. Jobs are revealed one by one, and each job consists of one map task and one reduce task. The map task can be arbitrarily split and processed on both machines simultaneously, while the reduce task has to be processed on a single machine and it cannot be started unless the map task has been completed. We first show that the general case of the problem reduces to the classical two machine online scheduling model with an optimal competitive ratio of 3/2. For a special case where the map task is at least as long as the reduce task, we prove that no online algorithm can be less than 4/3-competitive. An optimal Greedy algorithm with a matching competitive ratio is proposed as well.  相似文献

We propose a new typology of paternalistic leadership styles based on how leaders demonstrate authoritarianism and benevolence, the two essential components of this type of leadership. Benevolence-dominant paternalistic leadership refers to leaders' sole dependence on the use of benevolence without their strong assertion of authority, whereas authoritarianism-dominant paternalistic leadership is based mainly on authoritarianism itself; classical paternalistic leadership, which best fits early observations of paternalistic leaders, refers to the salient combination of both leadership components. We used two distinct samples and methods to test this typology and the association with subordinate performance. Across the two studies, a field investigation with Taiwanese military supervisor-subordinate dyads and a hypothetical scenario experiment with U.S. working adults, we found a positive relationship between classical paternalistic leadership and subordinate performance as strong as that between benevolence-dominant paternalistic leadership and performance. Our findings echo the phenomenon that paternalistic leaders tend to combine benevolence with authoritarianism to affect subordinate performance.  相似文献

本文基于2011年国际比较项目(ICP)设定的参考购买力平价(PPP)和亚太地区的数据,分别从定性和定量两个维度对使用参考PPP对更高层级PPP和最终PPP测算结果的影响进行了分析与考察。通过对参考PPP的梳理发现,其与经济现实的匹配性还存在诸多有待商榷的地方,应在加强对参加经济体现实情况了解的基础上进行适时修订。通过对比不使用参考PPP与使用参考PPP的更高层级中国PPP测算结果的变动情况发现,参考PPP的使用对部分小类、中类、大类的PPP测算结果有较大影响,但是对GDP总量PPP的影响有限。因此,ICP一方面应加强与参加经济体统计部门的协调与沟通,优化参考PPP的设计,另一方面应借助现代技术优化数据采集范围和效率,缩小对参考PPP的使用,以此从基础上优化PPP的整体测度水平。  相似文献
