Influence of Online Journalism on News Reach in Kenya

Online journalism is a type of journalism practised through digital platforms such as Facebook, Twitter, Yahoo, Google, websites and blogs. It has transformed traditional journalism by enabling media practitioners to propagate news in real time to their audiences. However, online journalism and news access has not received enough research. This study sought to investigate the extent to which digital journalism platforms influence news access in Kenyan universities. The study employed descriptive research design. The target population of the study was 63,817. Random sampling was used to sample 381 respondents from the sampled four universities. Data was collected using a questionnaire. The data gathered was analyzed using descriptive statistics using statistical Package for Social Sciences (SPSS) Version 17.0. Frequencies and percentages were used for analysis. The study established that digital journalism platforms are to a larger extent is accessible to internet users for news purposes. The study recommends that media practitioners should conceptualize their audiences and adopt digital journalism platforms that are accessible and interest them. Media houses and the government to develop internet infrastructure, formulate ethical framework and policies to guide online journalism practice in Kenya. The study also recommended the review in online journalism curriculum in learning institutions to make it more current in line with online journalism digital developments.

SIMS measurement of magnesium isotopic ratios in chondrites

Isotopic ratios of ^(Mg)/^(Mg) and ^(Mg)/^(Mg) have been measured for Mg-rich and Al-poor portions of Yamato, Plainview, Bruderheim, Leedey, Potter, Murchison, Leoville, Allende and Bondoc Peninsula meteorites with a Hitachi IMA 2A ion microprobe mass analyzer. Terrestrial samples of forsterite, biotite and anorthite have been also analyzed. In the three isotope plot, the data for ordinary chondrites of petrological types 5 and 6,an achondrite, a stony-iron meteorite and terrestrial samples are along the normal mass fractionation line through the reference point. On the contrary, the data for ordinary chondrites of petrological type 4 and carbonaceous chondrites fall on a straight line with the slope of unity with a few exceptions. This line can be explained to be the mixing of original magnesium and practically pure ^(Mg). This can be an evidence for the two component hypothesis of the primordial solar nebula
