浅议游线基础设施规划设计对地质景观脆弱性的保护

地质景观是自然山水旅游的核心资源,得到了世界各国的高度重视。对地质景观保护最为有效的做法是把地质景观比较集中的区域进行规划设计建成地质公园,形成保护与开发的良性循环。在地质景观规划设计过程中,游线基础设施对地质景观的脆弱性保护起着至关重要的作用。针对不同地质景观脆弱性,如何进行地质景观游线基础设施的规划设计是本论文要研究的主要内容。     

A bootstrap test for jumps in financial economics

An i.i.d. bootstrap is applied for the ratio test of Barndorff-Nielsen and Shephard (2006) for jumps in jump diffusion processes. Asymptotic validity is established for the bootstrap test both under the null of no jump and under the alternative of jumps. Finite sample simulation shows that the bootstrap test has more stable size than the ratio test of Barndorff-Nielsen and Shephard (2006).     

环境与就业维度下出口商品结构优化——以江苏为例

利用计量方法从环境和就业这两个指标来考察江苏出口商品结构优化,其中环境指标主要是通过碳排放指标来体现的。通过研究发现江苏九大类出口商品在环境和就业指标上都无此消彼长现象,其中对两指标都具显著影响力的为机械及运输设备,化学品及有关产品和按原料分类的制成品这两类出口商品仅对环境有着显著影响力,对就业不具显著影响力,至于其他种类的出口商品则对环境和就业这两个指标都不具显著影响力,最后得出江苏出口商品结构优化的最明确方向,即大力促进机械及运输设备的出口,抑制化学品及有关产品和按原料分类的制成品这两类出口商品的出口。     

网络流行语“中国大妈”和“中国式X”解析--基于认知及社会文化维度

伴随着新媒体的发展，“中国大妈”和与其结构类似的“中国式X”的网络流行语正在受到越来越多的关注。代表一种独特的文化现象的“中国式X”，本身就是一个语言模因，它的各种次生语言形式在模因的作用下得以在社会大众之间广泛繁殖和衍生。我们既可以从认知语言学的概念重叠和概念整合角度对“中国大妈”的形成及其所隐含的调侃语义进行解读，也可以从社会文化学领域的模因论视角对“中国式X”的传播进行探讨。     

《中华人民共和国标准化法》修订工作若干问题之探讨

近日,国家质量监督检验检疫总局以"质检办法函[2010]891号"文件下发了《关于征求对〈中华人民共和国标准化管理法(草案)〉意见的函》,专题征求对该法的修订意见。经认真研读,初步了解了该法修订草案的修法思路和特点,也发现了一些值得进一步研究和商榷的学术、技术问题,特介绍如下,与各界标准化同仁共同探讨。

Measuring the economic impacts of major sports events: the case of Formula One Grand Prix (F1)

This study was examined the new money generated from Formula One Grand Prix (F1) and the economic impacts of this new money on the host economy using input–output analysis. We find that the impact of the new money from non-local attendees or international attendees is more pronounced compared to that from local attendees. Also, F1 event appears to influence on sports-related industry as well as other industries such as manufacturing industry. Our findings suggest that the host cities should focus on increasing the non-local and international attendees in order to enhance the economic impacts of a sport event.     

A penny for your thoughts: Inducing truth-telling in stated preference elicitation

Contingent valuation often induces hypothetical bias. In a laboratory experiment, we test three calibration mechanisms: cheap-talk, consequentialism, and a new mechanism, the Bayesian truth serum (“BTS”). We apply the BTS in a “faith-based” format: subjects are informed about the purpose and potential efficacy of the BTS, but not its theoretical foundations. We find that real and hypothetical responses differ significantly; real and consequentialist responses are statistically indistinguishable; cheap-talk and the BTS eliminate bias inconsistently; subject characteristics interact significantly with treatment.     

英语归属歧义的成因与消解

归属歧义是由于句法结构不明确而使某些词语产生了不同归属所引发的歧义.英语归属歧义很容易产生,而且易于形成语言谬误,影响正常交际.其中限定不明确所引发的定语归属歧义、修饰不明确所引发的状语归属歧义、修饰不明确所引发的句子成分归属歧义比较常见.
