No full textCitation: Hause, B. M., Myers, O., Duff, J., & Hesse, R. A. (2016). Senecavirus A in Pigs, United States, 2015. Emerging Infectious Diseases, 22(7), 1323-1325. doi:10.3201/eid2207.151951Senecavirus A (SVA) has been sporadically identified in pigs with idiopathic vesicular disease in the United States and Canada (1–3). Clinical symptoms observed include ruptured vesicles and erosions on the snout and lameness associated with broken vesicles along the coronary band. A recent report characterized SVA in pigs in Brazil with similar clinical symptoms in addition to a higher proportion of deaths than would be expected in pigs 1–4 days of age (4,5). Several outbreaks of this infection in pigs were reported in the summer of 2015 in the United States; the more severe clinical features resembled those seen in outbreaks in Brazil (6). Subsequent testing by PCR of 2,033 oral fluid samples from material submitted during 441 routine diagnostic testing procedures (from 25 states) identified 5 SVA-positive cases (1%) (7). Besides affecting animal health, SVA infection is notable because its clinical symptoms resemble those caused by foot-and-mouth disease and vesicular stomatitis viruses. When vesicular disease is observed in US swine, mandatory reporting and testing of animals for foreign animal diseases are required
Genotyping porcine circovirus 3 (PCV-3) Nowadays: Does it make sense?
No full textThe discovery of a globally distributed porcine circovirus (Porcine circovirus 3; PCV-3) has led to intense research activity and the production of a large amount of molecular data. Different research groups have proposed several, not always concordant, genotypes for this virus. While such categories could aid an easier interpretation of PCV-3 molecular epidemiology, any classification, to be useful in practical settings, must be univocal and of help in the understanding of underlying biological features and epidemiology. Based on these premises, the possibility of defining PCV-3 genotypes was evaluated on the broadest available dataset of PCV-3 complete genome (n = 357) and open reading frame 2 (ORF2, n = 653) sequences. Genetic distance and phylogenetic clustering were selected as the main objective criteria. Additional factors, including the number of within-cluster sequences, host and geographic clustering, concordance between different genomic regions, and analysis method were als..
Consumer Information in the food service industry vs. food retailing
No full textIn order to define consumer expectations over a traceability and information system for the entire food supply chain, the information behaviour of consumers in the food service industry has been subject to an analysis for the first time. In comparison to consumers in retailing, significant differences appear in information seeking behaviour as well as in the information desired.meat traceability, consumer behaviour, food service industry, Consumer/Household Economics,

The Covariance Structure of Earnings and Income, Compensatory Behavior and On-the-Job Investments
No full textObservationally alike individuals who make different choices about on-the-job investments should have earnings profiles that differ in systematic ways. In particular, investments in non-specific human capital should result in lower initial earnings but higher earnings growth rates. Human capital models of this sort admit testing, then, by examining the covariance between the level of earnings and the growth rate of earnings. This paper reports estimates of this covariance using the sample covariance among income observations across time for the same individuals. The sample covariances are drawn from the Utah Panel Data, a panel of some 16,000 households with income and wealth observations at various intervals over the period from 1850 to 1900. The parameter of interest is negative. This estimate is robust to various specifications of the model. I also reexamine earlier work by Lillard and Weiss and Hause, who use data on earnings, and conclude that there is strong support for the on-the-job investment hypothesis using data from thre equite different sources covering different economies and different time periods.
