If the establishment is to boost competitiveness, it must have a quite good knowledge of target market so as to formulate some efficient strategies of broadcasting in its management, and the best way to resolve such problem is to eliminate cultural barriers with the adoption of the transmission of cross-cultural advertisements. This thesis shall research cultural diversities between eastern nations and western ones, and explore the effect the diversities have upon cross-cultural transmission, thus to propose an approach of eliminating cultural isolation with the adoption of effective techniques and manners of the transmission of cross-cultural advertisements.展开更多

The network has become the main place, people express their views so also. And the popularity of media enables consumers to easily express their products, services and other aspects of the topic, spread on the network at breakneck speed, and other users of the attention and support, thus forming a kind of public opinion, influence The development of enterprises, which will undoubtedly bring unprecedented pressure, constant attention, coupled with people's comments, forwarding, dissemination media, making the crisis spread, enterprises should not reasonable, effective, will enable enterprises to establish a sense of trust collapsed, brought a negative impact to the enterprise.展开更多

It is essential for today's reader/viewer to foster the capacity to critically deconstruct and reconstruct multimodal texts. And it is a must to expand traditional conceptions of literacy to multiliteracies. This paper, from the perspective of both theories and practices, explores and analyzes visual literacy, media literacy, digital literacy, critical literacy, and postmodern literacy in college English pedagogy, so as to fully develop the learners' multiliteracies展开更多

A comparative study of proxemics phenomenon between China and America finds that those two countries have a great differences. American seems especially sensitive to their body spaces, and Chinese don't care much about it. In the book The Silence Language, Edward hall first uses the term proxemics, and he has given a detailed analysis of proxemics. Proxemics is the study of spatial distances between individuals in different cultures and situations. Cultural factors for proxemics has a great influence, and the factors such as gender and religion also has a profound significance on proximics. This thesis will mainly analyze this phenomenon in the way of the definition and theory ofproximics, especially, the ways how people deal with the international culture situation. In order to improve the readers cultural accomplishment and ability to communicate, prevent the errors in the protocol, this paper will further explain how to solve these cross-cultural problems in cross-cultural context, especially for Chinese learners. With some fresh insights into international culture communication research, hopefully the readers may benefit from this paper and communicate with foreign people in a better way.展开更多

It was revealed that while the abruptly accelerated magma movement during starting period began eruption, the registered "gravitational" waves were being emitted and were propagating with the velocity greater than that of sound and seismic waves velocity. Alteration of "gravitational" waves velocity under the magma movement can be additional feature in prognosis of the start time of volcano eruption. The considered method might be effective when making up prognoses of underwater volcano eruption.展开更多

The malaria-only and TB-only models are considered first. Global stability disease-free steady states of the two sub- models does not hold due to the co-existence of stable disease-free with stable endemic equilibria, a phenomenon known as backward bifurcation. The dynamics of the dual malari^TB model with intervention strategies are also analyzed. Numerical simulations of the malaria-TB model are carried out to determine whether the two diseases can co- exist. Lastly, sensitivity analysis on key parameters that drive the disease dynamics is performed in order to identify their relative importance to disease transmission.展开更多
