Partisan US News Media Representations of Syrian Refugees
We investigate how representations of Syrian refugees (2011-2021) differ
across US partisan news outlets. We analyze 47,388 articles from the online US
media about Syrian refugees to detail differences in reporting between left-
and right-leaning media. We use various NLP techniques to understand these
differences. Our polarization and question answering results indicated that
left-leaning media tended to represent refugees as child victims, welcome in
the US, and right-leaning media cast refugees as Islamic terrorists. We noted
similar results with our sentiment and offensive speech scores over time, which
detail possibly unfavorable representations of refugees in right-leaning media.
A strength of our work is how the different techniques we have applied validate
each other. Based on our results, we provide several recommendations.
Stakeholders may utilize our findings to intervene around refugee
representations, and design communications campaigns that improve the way
society sees refugees and possibly aid refugee outcomes
Genome size and restriction fragment length polymorphism analysis of Vibrio cholerae strains belonging to different serovars and biotypes
The genome size of Vibrio cholerae has been determined by pulsed field gel electrophoresis following digestion of chromosomal DNA with endonucleases. The genome size of all the classical strains examined was about 3000 kb and that of El Tor biotype was 2500 kb. The NotI and SfiI digestion patterns of the genomes of several V. cholerae straimns belonging to different serovars and biotypes showed distinct restriction fragment length polymorphism (RFLP). RFLP analysis together with the genome size can be used to differentiate strains of different serovars and biotypes of V. cholera
