Perturbations of bounce inflation scenario from modified gravity revisited
In this work, we revisit the perturbations that are generated in the bounce
inflation scenario constructed within the framework of theory. It has
been well known that pure theory cannot give rise to bounce inflation
behavior, so aside from the gravity part, we also employ a canonical scalar
field for minimal extension. We calculate the perturbations in theory
using the well-established ADM formalism, and find various conditions to avoid
their pathologies. We find that it is indeed very difficult to obtain a healthy
model without those pathologies, however, one may find a way out if a potential
requirement, say, to keep every function continuous, is abandoned.Comment: 5 pages, 1 figures. Comments are welcom
What Appeals to the Chinese Customers? Content Analysis of Chinese Advertisements in Newspaper and on TV
This study examines the advertising appeals delivered, and the cultural values reflected in Chinese advertisements in newspaper and on TV. It proved that the most frequently used advertising appeals are 'technological', 'status', 'enjoyment', 'vain', 'natural', and 'healthy' for print ads, 'effective', 'youth', 'enjoyment', 'technological', 'vain', 'healthy', 'traditional', 'family', and 'status' for TV ads. Most of them are product category related, but others, such as 'enjoyment', 'healthy', 'status', are universal for any products. The origin of brands makes a difference only on some appeals. Local Chinese brands tend to use more 'traditional', 'community', 'cheap' and 'morality' which are inherent in traditional Chinese culture. However, global and local brands are becoming similar on the choice of most advertising appeals. Among cultural values, group/consensus appeals are significantly more than individual/independence appeals; soft-sell appeals are significantly more than hard-sell appeals; modernity/youth appeals are significantly more than traditional/veneration of elderly appeals; product merit are significantly more than status appeals; symbolic values are significantly more than utilitarian values. Cultural values differ by product category but not by country of origin. Between global brands and local Chinese brands, there is no significant difference on cultural values except that local brands' TV ads keep more group and traditional values. The elements of 'Chinese culture' are broadly used by both local and global brands. Symbolic visuals are preferred to only literal visuals. Website addresses are shown in most print ads. Corporate image, new product ideas and life style are also given attention to. TV ads convey more group/consensus, soft-sell, traditional/veneration of the elderly, oneness of nature and symbolic values, but less hard-sell and status values than print ads. The implications of this research are: 1. Advertisers in China need to consider all the related variables-product category, origin of brands, media type, target market and culture-when choosing advertising appeals and cultural values. 2. Cultural adaptation is necessary and helpful. The issue is not what advertising appeals to pick, but how much Chinese culture to be added in delivering them
