An attempt was made to determine the mechanism of implementation of this phenomenon in these periods the example of the news program ＂Facts＂ on ICTV channel and news on the TV channel ＂1＋1＂. The author makes two models of moral panic mechanism＇s formation： during the period of sociopolitical stability and in the period of sociopolitical crisis. Furthermore, it identifies the comparative characteristics of moral panic formation during the period of the sociopolitical stability and sociopolitical crisis.展开更多

There is a consensus among political economy scholars that gives advertisers power over media content. It has also been argued that advertisers usually do not associate with ideological enemies. This research therefore sought to find out whether political advertisements especially, during election time, influence media content and whether political advertisers do not associate with media houses they are not ideologically compatible with. During election times, political parties also become big advertisers and newspapers together with broadcasting media compete to get advertisements from political parties so as to boost their financial fortunes. The research focused on the March 29, 2008 Zimbabwe harmonised elections with Network Guardian News a Kwekwe based privately owned community newspaper being used as a case study. This study utilised critical discourse analysis on purposively selected newspaper stories published during the period under study; while in-depth unstructured interviews with editors, reporters from the newspaper and politicians were also conducted to gather information. The findings revealed that in spite of the pro-ZANU-PF Network Guardian News newspaper carrying both MDc and ZANU-PF advertisements, its editorial stance remained hostile to the MDC-T party.展开更多

The proximity of the channel dimension, the Debye length, and the size of biomolecules such as DNA and proteins gives the unique features of nanofluidic devices. Of various unique properties of the nanofluidics, mass transport in nanochannel plays determining roles in fundamental reaches and practical applications of nanofluidic device. Thus, much work including numerical and experimental researches has been performed to investigate the mass transport behaviors in nanofluidic devices. This review summarizes the fabrication technologies for nanofluidic devices, the mass transport behaviors in nanochannel, and their applications in bioanalysis. The main focus will be laid on the effects of nanochannel size and surface charge on mass transport including electrokinetic transport of charged analytes, diffusion of electric neutral molecules, ionic current rectification, concentration polarization, nonlinear electrokinetic flow at the micro-nanofluidic interfaces.展开更多
