Analysis on traffic characteristics and transmission efficiency of instant messager services

Traffic characteristics of several typical instant messager services under certain scenarios are firstly analyzed,based on real-time data collected in the commercial mobile network.Then criteria for the evaluation of the efficiency of the mobile network for the transmission of packet services are proposed in both transport layer and physical layer over air interface.The transmission efficiency of IM services is evaluated and compared under the proposed criteria.Furthermore,a so-called smart resource adaptation algorithm is verified in the effectiveness of improving the wireless transmission efficiency.Finally,improvements to the smart resource adaptation are proposed to further improve the wireless transmission efficiency,and its effectiveness is verified by the calculations.

Hidden Crises and Communication： An Interactional Analysis of Hidden Crises

In this paper I describe the ways in which the communication discipline can make a hidden crisis transparent. For this purpose I examine the concept of crisis entrepreneurship from a communication point of view. Using discourse analysis, I analyse the discursive practices of crisis entrepreneurs in the domain of education in the Netherlands. This paper is part of my Ph.D. project in which I examine the dilemmas encountered by crisis entrepreneurs and the interactional solutions they choose in addressing a crisis. In my Ph.D. project I have analysed how crisis entrepreneurs use discursive practices： （1） to show thefactuality of the problem. For example, the way the problem is presented is too theoretical and is not a problem in reality; （2） to present the credibility of the messenger as an authentic, legitimate spokesman. Crisis entrepreneurs may be accused of wanting to attract attention to their own cause; （3） to create the accountability for the problem and the solution. For example, crisis entrepreneurs can be accused of nursing personal grievances or of drawing attention to the issue without actively attempting to solve it. The conclusion is that a communication professional is able to recognize a problem raised by crisis entrepreneurs. Knowledge of interactional dilemmas helps communication professionals understand the potential of crisis entrepreneurs. A communication professional can therefore contribute to the recognition of crises by acknowledging that a crisis entrepreneur is someone who can have a strong hand in the public agenda, i.e., public affairs that are important to the authorities.

Open Government and ＂E-Government＂ in Russia

With the advent and widespread information and communication technologies, pace of human activity has accelerated markedly new industries, new management techniques. And in the world community, now prevalent idea of democracy with equal rights and freedoms for all citizens of a democratic state is a risk and a challenge to the integrity of a community. Against this background, it becomes important not only process control, but also a system of communication between society and the state. For effective interaction between society and the state, the government needs a new, streamlined platform for the provision of public services. This site was e-government. Currently, the concept of ＂open government＂ is implemented in the administration of the state in all developed countries. This paper deals with modern communication mechanism of the state and society in Russia, for example, ＂e-government＂, and the effectiveness of this mechanism in the process of changing demands of society.

Modeling Corporate Communication in Social Media

Social media are used in corporate communication more and more actively. Operating in conditions of the attention economy companies are fighting for the audience attention and that＇s why social media become valuable for them. However, the popular corporate communication theories and models were created at the time, when social media did not exist and could not fully reflect the special nature of the communication that is typical for the social media environment. This generates the need for a new corporate communication model. As a result of analysing the habits employed by users and br^mds in social media, as well as the existing models of corporate communication, the author proposes an ＂added value model＂, which illustrates the process of corporate communication in social media. According to this model, the process of corporate communication in social media is ongoing taking into account both the company＇s and users＇ goals, selecting particular social media on the basis of their message and enriching communication with a communicative added value. The element of added value indicates that social media have a potential to become not only a communication channel, but also a platform, which provides a limited or full range of services, service support, and satisfies users＇ needs. Thus, the proposed model could serve as a point of reference and evaluation, which is crucial for starting or improving corporate communication in social media.
