Abstract

Both the current long term telecommunication trends toward optical networking and the recent growth in information bandwidth have pushed the necessity for improved optical communications. Our fabrication approach, which leverages our expertise in solid freeform fabrication in conjunction with sol‐gel technology, has advantages over these other methods because of the inherent benefits of using a direct‐write philosophy, such as design flexibility and minimal post‐processing. However, fabrication of such novel optical components requires extensive knowledge of their light guidance capabilities. This paper shows the technical issues involved in both modeling and characterizing small optical components fabricated by locally densifying sol‐gels in a modified direct‐write process.

Abstract

Purpose

Consumers of minority race/ethnicity in the US experience greater rates of foodborne illness, including Salmonellosis and Campylobacteriosis. Previous focus group research with minority consumers identified food handling and purchasing practices which might increase their risk for foodborne illness. The purpose of this paper is to determine whether practices identified in focus groups were common among a larger sample of the population.

Design/methodology/approach

A survey including focus group-derived, culturally themed questions about food handling was developed and administered. Phone surveys were administered in English, Spanish, and Chinese from September-November of 2011 in Philadelphia, Pennsylvania.

Findings

Minority consumers were significantly more likely than Caucasian consumers (p < 0.05) to purchase live poultry and to purchase eggs unrefrigerated. Minority consumers were also more likely to report cooking offals and cooking a whole turkey overnight. Washing raw poultry was found to a prevalent behavior (85.7-89.1 percent) among Caucasians as well as minority consumers (95.0-97.9 percent).

Research limitations/implications

This research surveyed consumers in a limited geographic area therefore results may not be generalizable to other geographic areas.

Originality/value

The existence of unique unsafe food handling practices among minority consumers highlights the need for researchers to understand food handling practices of minority consumers in their countries. It also highlights the need to develop culturally appropriate safe food handling messages for immigrant and minority consumers. Additionally there is a need to better advise all consumers not to wash raw poultry.
