With the impetus of the WTO and the further opening of China's international service trade in education, this paper is based on the background of China's national strategy "one belt & one road", analyzing Guangzhou higher education, its internationalization driving force and popularization value, ranging from the perspectives of higher education resources excess, the domestic university funding cuts, and the transnational education services output in developed countries to alleviate its school funds shortage to further introduction of foreign high-quality educational resources due to not fully meeting the requirements of domestic demand in developing and less developed countries, with expectation to promote the development of education internationalization healthily and orderly. 展开更多

This study explained the importance of environmental protection in tourism development and illustrated the relationship between recreational resource valuation and environmental consideration.We compare different models of travel cost method and reiterates long-time existing problems of multi-destination and treats of time opportunity cost(TOC).Taking Jiayuguan's cultural sights as an example,we establish an updated method called multidestination zonal tourism cost method to evaluate the recreational values(RVs) of selected three cultural sights.We divide trip packages of Jiayuguan's tourists into 11 portfolios.Each portfolio can be seen as a separate commodity,and each commodity has its own demand curve.According to demand curves we can calculate consumer surplus(CS) of different portfolios of tourist destinations and later we sum up the total travel costs(including travel expenditure and TOC) and CS to come to the RVs of each portfolio.We then apply suitable proportions to calculate the RVs between different destinations in the portfolio.In the end,we add up all the RVs calculated for the objective destination.Using this method,we draw conclusions that Jiayuguan's RV in 2006 includes national and international values,summing up to 738.4762 million yuan.The tourist expenditure,CS and TOC of Jiayuguan is proportionating 62.96,32.28 and 4.76%,respectively.This study is also an example of non-market valuation of cultural tourism resources. 展开更多

The aim of this work is to study the interaction of spoken words and images that are used within programs targeted to popularize knowledge among teenagers. We will look into the program Bit@bit developed by Television de Catalunya, which is intended to disseminate computer concepts, tools and procedures. In this kind of program, one can find spoken language (on/off screen voices, interviews, etc.), other oral material (sounds, music, songs), written language (descriptions, title sequences, inserts and Uniform Resource Locator, or electronic addresses), and other visual material (film cut images, advertising, other TV programs, cartoons, films, both location or studio images, depicting reality, or computer screens, or logotypes). The profusion of multimodal elements used in this program helps to keep the young audience's attention. The use of references to their world or knowledge, as a target group, is based on interplay among different semiotic strategies. At the same time, the entire program's multi-segmentation into short video clips, combined with a fast paced sound track helps its audience to understand the specialized explanations presented. Of all the multimodal wealth that the program presents, we will concentrate only on the relationship between the words and the images (leaving other secondary semiotics to one side), the main strategy for achieving the objective of transmitting knowledge and winning adolescent audiences. 展开更多
