Research On Packaging Design Innovation Of Chongqing Hot Pot Under Single Economy, Zhang Da-Lu, Tang Lan-Ling Dec 2021

Research On Packaging Design Innovation Of Chongqing Hot Pot Under Single Economy, Zhang Da-Lu, Tang Lan-Ling

Food and Machinery

Chongqing hot pot has seized the tide of “single economy” and changed the dining form of hot pot with many people eating, and then broke the traditional consumption scene of hot pot. The packaging of Chongqing hot pot gradually developed to miniaturization and convenience and reflected the emotional resonance with consumers in the packaging. Moreover, it presented the social attributes of the packaging, and met the consumption needs of consumers. “Single economy” and chongqing hot pot, the two completely different attributes of the individual integration, promote the future development of Chongqing hot pot packaging design.

Penn State Extension Services And Plain People: An Inside Perspective On A Trust-Based Relationship, Phillip Martin Dec 2021

Penn State Extension Services And Plain People: An Inside Perspective On A Trust-Based Relationship, Phillip Martin

Journal of Amish and Plain Anabaptist Studies

This perspective on Penn State Extension Services and plain people is based on my personal experiences as a plain person, in which I interacted with Extension Services first as a farmer, and then (while working on a doctorate) as a part of the Extension system. Penn State Extension started over a century ago and was deliberate in reaching out to plain (conservative Anabaptist) farmers since the beginning, which led to a history of trust-based cooperation. For all these successes there remain challenges to effective cooperation with certain plain individuals and subgroups. I suggest these challenges are broadly similar to those …
