Given such differences, the analysis of destination risk and its dimensions is of substantial interest.

In order to analyze qualitative observations, methods of quantification or optimal scaling have been proposed by Fisher, Guttman, and Hayashi. According to these methods, scores are assigned optimally in some objective and operational sense to the qualitative categories. The present paper mainly reviews Hayashi's four methods of quantification from the mathematical point of view. They are widel...

The research objective of this study was to explore the cultural differences and challenges encountered by the Chinese Immersion Teacher (CIT) and how the CIT deal with the cultural differences in the immersion classroom. A qualitative case study approach was chosen for this research. The participant was a novice kindergarten immersion teacher who was born and educated in a Chinese-speaking cou...

We have isolated seven DNA fragments from Caenorhabditis elegans that enhance the mitotic segregation of autonomously replicating plasmids in the yeast Saccharomyces cerevisiae. These segregators, designated SEG1-SEG7, behave like isolated yeast chromosomes: they increase the stability and simultaneously lower the copy number of circular plasmids during mitotic growth in yeast. During meiosis, ...
