How Knowledge, Experience, And Educational Level Influence The Use Of Informal And Formal Sources Of Home Canning Information, Gina M. Taylor, Allison Nichols, Ami Cook

The Journal of Extension

In the research study reported here, West Virginia University Extension educators surveyed the public about their current canning knowledge and practices in 2010. The results showed that educational background and canning experience were the most important factors in understanding how clients seek canning information and the degree to which they preserve foods safely. Home canners primarily use family members as first sources of canning information and consider Extension one of the less important sources of information. Improved marketing efforts are needed to increase canners' understanding of the importance of formal canning sources, especially those offered by Extension programs.

Spectral Band Selection For Ensemble Classification Of Hyperspectral Images With Applications To Agriculture And Food Safety, Sathishkumar Samiappan

Theses and Dissertations

In this dissertation, an ensemble non-uniform spectral feature selection and a kernel density decision fusion framework are proposed for the classification of hyperspectral data using a support vector machine classifier. Hyperspectral data has more number of bands and they are always highly correlated. To utilize the complete potential, a feature selection step is necessary. In an ensemble situation, there are mainly two challenges: (1) Creating diverse set of classifiers in order to achieve a higher classification accuracy when compared to a single classifier. This can either be achieved by having different classifiers or by having different subsets of features for …

Amyloid Fibrils: Potential Food Safety Implications, Michael Greger

Michael Greger, MD, FACLM

The demonstration of oral Amyloid-A (AA) fibril transmissibility has raised food safety questions about the consumption of amyloidotic viscera. In a presumed prion-like mechanism, amyloid fibrils have been shown to trigger and accelerate the development of AA amyloidosis in rodent models. The finding of amyloid fibrils in edible avian and mammalian food animal tissues, combined with the inability of cooking temperatures to eliminate their amyloidogenic potential, has led to concerns that products such as pâté de foie gras may activate a reactive systemic amyloidosis in susceptible consumers. Given the ability of amyloid fibrils to cross-seed the formation of chemically heterologous …

The Challenge Of Exemplification In Crisis Communication, Deborah D. Sellnow, Timothy L. Sellnow

Journal of Applied Communications

This case study characterizes the crisis communication challenges and potential response strategies of organizations facing crises of perception created by media exemplars. Exemplars are created through repeated news stories made memorable by highly vivid language, shocking visual materials, and evocative personal testimonies. ABC’s portrayal of Lean Finely Textured Beef as “pink slime” is provided as a case for analysis. The study concludes that organizations responding to crises of perception are at an extreme disadvantage when their standard operating procedures are portrayed negatively as exemplars. In addition, stigmatization increases an organization’s susceptibility to exemplars. Finally, appeals to neutral parties have the …

The Rise Of Transnational Private Meta-Regulators, Paul Verbruggen, Tetty Havinga

Transnational Business Governance Interactions Working Papers

In recent years scholars from various disciplines have turned their attention to transnational regimes of regulation that are chiefly developed outside state-driven frameworks. The rise of such "transnational private regulation" has also led to the emergence of private meta-regulation. The term 'meta-regulation' commonly refers to processes through which a regulatory body oversees another and sets standards for its activities or performance of regulation. In the public domain, meta-regulation has been associated with the devolution of regulatory activities by a statutory body to private actors with the view to enhance voluntary rule compliance, awareness of responsibilities among the regulated and reduce …
