语言是文化的裁体,文化支配着语言。不同文化背景的人们在交际的过程中,由于文化差异,交流双方很容易产生文化障碍。要获得跨文化交际的最佳效果,我们不仅要掌握语言本身的规律,更要了解语言所承载的深刻文化内涵,通过一些手段来培养学生的跨文化交际能力。 相似文献

ABSTRACT Supranational organisations can only confront politico-economic issues that are recognised as important. Typically, issues gain recognition either when they provide an external shock to the system, shaking political actors into action, or when they are framed as important in policy networks concerned with developing the appropriate scientific approach. Ideally political and scientific actors align in creating pressures to recognise the issue as salient and to mobilise organisational responses. Issues differ in their capacity to be driven by both political and scientific pressures, creating crisis management, technocratic, and reform agenda outcomes. Here we explore a further variation, where pressures around an issue are insufficient, creating a policy vacuum. We examine one such policy vacuum in Europe: demographic change. This issue belongs to no particular Directorate-General in the European Commission, but is subject to policy frames from DG EMPL and DG ECFIN. Without sufficient political and scientific pressures, no particular policy position is occupied and advocated despite recognition of the issue’s importance. We discuss the role of policy vacuums and the need for their identification in political economy research. 相似文献

In many markets, consumers use attribute information to assess the value they expect from purchasing a product or service. This includes many low involvement experience goods including take-out food, many packaged good categories and restaurants. In these markets, quality differences exist but many differences are horizontal in nature: the consumer is interested in finding a product that meets her unique tastes. Beyond ensuring that consumers know the brand, the category and the price; it seems advertising should provide consumers with attribute information. However, a significant proportion of advertising does not provide it. In fact, within the same category, competitors respond to messages that emphasize detailed attribute information with messages that are devoid of attribute information. These messages are uninformative about product attributes. We explore how competition in a differentiated market is affected by the ability of a firm has to choose uninformative messages. We construct a model to investigate the factors that affect a firm’s decision to use advertising with detailed attribute information or advertising that does not provide it. The model demonstrates that content decisions about advertising are affected by the differences between products, the range of heterogeneity in consumer tastes and the degree to which costs increase as a function of the quantity of information in advertising. Surprisingly, even when the cost to increase the quantity of information in advertising is low, uninformative campaigns can be more profitable than campaigns with attribute information. The analysis also demonstrates that firms can be more likely to provide attribute information when there are less consumers that are attribute-sensitive. Finally, the model shows that uninformative messages can create “artificial differentiation” in some situations. 相似文献

体育课程内容设计是指依据一定的课程目标,将体育学科中纷繁的构成要素组合成具有某种特定的形式结构的活动。针对目前部分高校体育课程内容设计的比较和分析,以湖南工业职业技术学院为例,从课程内容设计的依据,课程内容的结构,以及课程内容设计的资源保障等方面解读和分析,主客观两方面因素决定着休闲体育课程内容设计的原则,目前高校体育课程结构设计确实存在问题,要发挥出课程设计的整体优势,课程结构各要素的完整性及其有机联系而形成的系统性是设计的实质核心;湖南工业职院以高校公体课"三自主"的原则为纲,开发灵活互动的"三结合"模式,以及学分制课程模式的基础上,所开设的休闲体育课程内容及结构符合休闲体育课程发展的方向;此外,课程资源的丰富和全面是课程内容设计得以顺利实施的保障。 相似文献
