汉语方言中来源格、处所格和目标格融合现象初探

本文通过对汉语38个方言点中49组介词融合(syncretism)现象的考察,发现汉语来源格、处所格和目标格之间的融合现象可以通过两种融合模式加以说明。其一是双向融合模式,即处所格和来源格可以双向融合,处所格和目标格也可以双向融合,因此出现三个格用一个词表示的语言现象,在这种模式中来源格与目标格融合需要另外解释。其二是单向循环融合模式,即处所格发展出目标格,目标格发展出来源格,来源格再发展出处所格,形成一个循环。汉语方言中来源格、处所格和目标格存在错综复杂的关系可能是多种因素综合作用使然。     

隐秘重负下的疯狂与毁灭——《雷雨》悲剧根源新探

关于《雷雨》的社会问题剧、伦理情爱悲剧、命运悲剧等等各种解释不一而足,但似乎都未触及悲剧的本质。品读、观赏这部剧的时候,实际上也是作者为我们抽丝剥茧,将秘密逐次揭开的过程。隐秘重负下的疯狂与毁灭或许成为《雷雨》悲剧的终极根源。     

南水北调中线水源地生态与经济系统动态分析——以汉中市为例

把生态与经济系统耦合类型划分为生态良好经济发达型、生态良好经济欠发达型、生态脆弱经济发达型、生态脆弱经济欠发达型四种。基于生态足迹理论,构建了生态资本效用指数、生态&经济协调指数,对南水北调工程水源地汉中市1990～2009年生态经济系统运行态势进行了动态分析。结果如下:生态资本供需变化较大:1993年以前为生态盈余,1994～2001年为基本持平,2002～2009年为轻度赤字;生态压力逐渐增大,由1990年的0.74提高到2009年的1.15;2009年的生态资本转换效用是1990年的1.82倍,同期生态与经济协同发展指数提高了2.01倍。研究表明,汉中市生态与经济系统目前属于生态良好经济欠发达型。据此,提出了生态资源经济化的路径与建议。     

BOC(10,5)信号的调制与解调

讨论了卫星导航中BOC调制解调的原理和实现方法，并着重研究了接收机的码跟踪技术。首先阐述了BOC信号体制出现的国际背景及信号特点，并介绍了BOC（10，5）信号形式和频谱特性，然后简要介绍了信号调制的方法，最后重点讨论信号解调方法。针对BOC信号多峰结构的自相关特性，分别研究并比较了两种解调方案，最后综合两者特点提出了组合式解调恢复方法。

Is tourism just another staple? A new perspective on tourism in remote regions

According to recent research, countries may have a positive image from a tourism perspective, but they may be seen as lacking from an economic or political viewpoint. As governments and destination management organisations spend large sums of money in promoting tourist attractions, the question of whether these activities also influence other aspects of a country's image becomes relevant. The objective of the research is to determine the effect of tourism promotions on the image of the country and that of the destination as two separate concepts, in the case of Israel, a country subject to continuous conflicts. A 2?×?2 quasi-experimental design is utilised to investigate the influence of tourism promotional brochures. Additionally, a comparative perspective is used to determine whether people from diverse countries and backgrounds may be affected differently by the same information. The findings confirm that tourism brochures influence not only the image of the destination, but also that of the country. These effects are found to be different for respondents from the two different countries compared. The article focuses on understanding how tourism communication strategies may also be used to improve the image of a country, with potential benefits for international marketing and international relations.     

外语听力理解的主要障碍及其教学对策

听力材料的特殊性和学习者自身在外语水平、文化知识方面的欠缺是干扰听力理解的主要因素。提高学生听力,应采取将多种媒体用于听力教学,创造语言环境,培养听力技巧,精听与泛听相结合等多种对策。

The dynamics of tourism’s carbon footprint in Beijing,China

Abstract

Beijing is an important hub for global tourism, but the extent of tourism’s contribution to Beijing’s carbon footprint remains unclear. We integrated an environmentally extended multiregional input–output model and the tourism satellite account in a study to estimate the dynamics of Beijing’s tourism-related carbon footprint in the post-financial crisis period. Our findings indicate that from 2007 to 2012, whereas the carbon footprint of inbound tourists in Beijing steadily decreased, that of domestic tourists increased. The composition of carbon footprints for the consumption activities of inbound and domestic tourists differed substantially. We also traced the spatial distribution of carbon sources associated with tourism consumption in Beijing. In light of our findings, we offer recommendations to target the adoption of low-carbon consumption patterns by domestic tourists, and energy optimization of service suppliers by increasing energy use efficiency and the renewable energy ratio. In addition, we recommend that public and government should seek to lower energy costs and reduce carbon emissions throughout the life cycle of commodities. We conclude that the government and tourism authorities should actively promote carbon and wider environmental awareness, and that producers must seek to improve the efficiency of their energy use by reducing carbon emissions at source.
