Determinants of wage arrears and their implications for the socioeconomic wellbeing of China's migrant workers: Evidence from Guangdong province

The recent unprecedented scale of Chinese migration has had far-reaching consequences. Within China, many villages have been drained of their young and most able workers, cities have been swamped by the ‘floating population’, and many rural migrants have been unable to integrate into urban society. Internationally, the Chinese have become increasingly more mobile. This Handbook provides a unique collection of new and original research on internal and international Chinese migration and its effects on the sense of belonging of migrants.

Overweight and obesity in children from Shenzhen, Peoples Republic of China

We describe overweight and obesity prevalence in Shenzhen school children (2146 girls and 2428 boys) aged 7 to 12 years, Guangdong Province, China. Nineteen percent of boys and 11% of girls were overweight or obese. Boys had odds of almost 2 to 1 (1.92, 95% CI 1.62,2.27) of being overweight or obese compared to girls and children aged 9 years and over were at greater odds of being overweight or obese than those aged 7 years (p<0.05). Overweight and obesity prevalence among children from Shenzhen rivals that of children from developed nations. Current obesity levels in Shenzhen may represent future levels for urban China.

Epidemiological and evolutionary inference of the transmission network of the 2014 highly pathogenic Avian Influenza H5N2 outbreak in British Columbia, Canada

The first North American outbreak of highly pathogenic avian influenza (HPAI) involving a virus of Eurasian A/goose/Guangdong/1/1996 (H5N1) lineage began in the Fraser Valley of British Columbia, Canada in late November 2014. A total of 11 commercial and 1 non-commercial (backyard) operations were infected before the outbreak was terminated. Control measures included movement restrictions that were placed on a total of 404 individual premises, 150 of which were located within a 3 km radius of an infected premise(s) (IP). A complete epidemiological investigation revealed that the source of this HPAI H5N2 virus for 4 of the commercial IPs and the single non-commercial IP likely involved indirect contact with wild birds. Three IPs were associated with the movement of birds or service providers and localized/environmental spread was suspected as the source of infection for the remaining 4 IPs. Viral phylogenies, as determined by Bayesian Inference and Maximum Likelihood methods, were used to validate the epidemiologically inferred transmission network. The phylogenetic clustering of concatenated viral genomes and the median-joining phylogenetic network of the viruses supported, for the most part, the transmission network that was inferred by the epidemiologic analysis.
