Due to the fact that most magazines are created with an intention of convincing readers of various ideologies, most linguists would consider the use of loanwords to give a comprehensive presentation of ideas. Incorporating English loanwords is not only a requisite tool for integrating and addressing the cultural differences between various communities across the globe, but also acts as a bridge that fills the conceptual gaps that exist in various languages. This is no longer the job of a linguist, because there are many other ways through which the people of a particular country can adopt a loanword （e.g., social media）. Also, it enriches the recipient language and puts its citizens up to date with the latest developments and inventions.展开更多

Online newspapers offer their audience several opportunities to participate, for example, by submitting comments on articles or uploading pictures/videos. Audience participation has also emerged as a fast growing research field： The motives for focusing on audience participation have been analyzed and the kind of participatory opportunities that news media offer the audience have been mapped. Also, questions on whether audience participation should be regarded as an advantage or disadvantage to professional journalism have been discussed. This study relates to the latter perspective as it examines media practitioners＇ perceptions of audience participation. By focusing on the case of Swedish newspaper journalists, this study analyzes how audience participation is perceived to affect journalistic work and to what extent such participation is believed to benefit journalism. Based on a representative survey of Swedish journalists, conducted in 2011-2012, and a survey of journalists working at three local morning papers in Sweden, conducted in 2009, the analyses reveal a rather ambivalence attitude to audience participation among the journalistic corps.展开更多

Through an analysis of a sample of stories from both the paper＇s print and online editions, the study traces the origins of the broadsheet＇s ostensibly unflagging pro-ZANU-PF editorial positions, turning to article analysis to critically probe not only the motive but also the impact of the newspaper＇s assumed open allegiance to the revolutionary party. In a nation believed battered by perceived state brutality and widening political differences, The Herald has been accused of significantly influencing the pace of dictatorship while guardedly manipulating information to prop up President Robert Mugabe＇s party. So important has the paper become over the years that its often uncompromising, one-sided style of reporting has earned it praise among militant ZANU-PF hardliners while bitterly attracting widespread criticism from critics of the long-serving party.展开更多

It has chosen XRF to make a quantitative analysis. Based on multiple regression theory it regard fiberglass filter paper＇s quality, element content and the quality of the loaded sample as independent variable, while the element＇s quality that the sample has collected as dependent variable. Furthermore, it has established four multiple quadric response surface models which concerning Ca by using of Mathematica and Matlab： Y = 0.8649-2.094x1-2.08x2 -1.375x3-10.58x1x2＋8.53x1x3＋1.549x2x3-3.443x1^2＋6.555x2^2＋6. 547x3^2; Y = 0.8649-2.094x1-2.08x2-1.375x3; Y = 0.8649 -2.094x2-2.08x2-1.375x3-3.443x1^2＋6.525x2^2＋6.547x3^2 ; Y =0.8649-2.094x1-2.08x2-1.375x3-10.58x1x2＋8.53x1x3＋1.549x2x3. After comparison it has finally found the best model. In combining with the sample it present a multiple data fitting analysis method which could adjust the fiberglass filter paper model accordingly.展开更多

To investigate the performance of the achieved catalyst, which is activated through calcination, the aspects of calcination temperature, reaction time, mole ratio of methanol to oil, catalyst addition percentage, and reaction temperature are concerned. Characterization of catalyst reveals that LM could be activated through calcination to transform the carbonate and hydrate of calcium into the oxide forms and higher calcination temperature could lead to stronger basic strength. However, N2 adsorption results indicate that higher temperature causes the sintering of the catalyst and shrinkage of the catalyst grains. When LM is activated at 800℃ （LM-800） and the reac- tion is carried out at 64℃ with a methanol to oiL mole ratio of 15：1, catalyst addition percentage of 6%, and reaction time of 2 h, the maximum transesterification conversion of 94.35% could be achieved. Reusability of LM-800 is also investigated com- pared with laboratory grade CaO in five reaction cycles and the results indicate that the catalysts derived from LM can be used as an economic and efficient catalyst for biodiesel production.展开更多
