- Yesterday, I drove to Chicago and back for a six-hour wake, so I'm even
more behind than normal. I will do my best to catch up this weekend.

Notes from SA
Some of the metrics for risk - Dread or lack thereof, Knowledge, Analyze, Severity
Some of the broad categories of technology that Lyons introduced were:
b. Food packaging in order to achieve – General and intelligent packaging – flexibility, etc. Biodegradable composites. Antimicrobial or oxygen scavenging properties (kills small things like bacteria, and takes away oxygen so that bacteria doesn’t grow)
c. Food enhancement – nutrition, appearance, texture. Food safety or preservation, storage.
Petroski would say that as with all technologies, food technologies also have certain risk factors. he might be more careful because of the liability with consumers and food.
Pool (How society shapes technology) would want us to think about fads in food, nutrition, and health as we assess new technologies about food.
When/how do we regulate a technology? What are the ways that people engineer around regulations? We need to see if a certain technology is an attempt to engineer around a regulation and, if so, what the implications are for doing so.
Notes from TD
Food additives can be good and bad!
The agriculture/food product industry uses industrially-sourced radiation
to preserve the shelf life of certain food stuffs.
A host of regulatory issues arise around nano-particles. For example,
the FDA regulates chemical substances defined by their composition,
and nano-particles do have the same composition as their larger
counterparts. Does that mean that substances approved for macro use
also have implicit permission for use on the nano scale? Companies argue
so, but they also use nano-particles for their unique effects. How can
regulation legally confront this?
We don't definitively know how nano-particles behave during digestive
uptake and processing.
Consumer opinions are very important for the long-term success of
products. "Will we be wood by nanoparticles or repulsed by them?" We don't
know if they will end up going the way of other "high-tech" food stuffs.
"Big picture" issues: Lenses, Genres, Individual technologies
Take five minutes to think about the following questions.
What new questions (or not so new questions) do Lyons and the authors
ask us to use when we encounter a new technology?
- What are the risks of that technology?
- For food: What happens when you consume it?
- For all technologies: To the people who manufacture it.
- E.g. blue hands in nanosilver
- E.g. inhalation and skin for nanoparticles
- Metrics for risk
- Dread or lack thereof
- When/how do we regulate a technology?
- What evidence do we rely on?
- What technologies do we use to build evidence?
- What are the ways that people engineer around regulations?
- Alternately: Is this technology an attempt to engineer around a
regulation and, if so, what are the implicatios?
- We also build technologies to understand/assess technologies.
- How do we analyze new technologies?
- What technologies do we need to analyze technologies?
What are the broad categories of technology that Lyons introduced?
- Food packaging in order to achieve -
- General packaging goals - flexibility, etc.
- Intelligent food packaging - Is this food still good?
- Antimicrobial or oxygen scavanging properties
- Kill small things (e.g., bacteria)
- Takes away oxygen - helps kill microbes/bacteria
- Helps preserve in other ways, too
Food safety, preservation, storage
- Food irradiation
- Heat treatment
Food enhancement - Nutrition, Appearance, Texture
Regulation (is regulation a technology?)
What are other issues Lyons considered?
What are some particular technologies within each category that Lyons
Applying lenses: Small Group
Technologies to think about:
- Food irradiation
- What technologies that Lyons discussed would Berry consider positive?
(For this question, you can go beyond the particular ones above.)
- Back to his nine principles ... danger (particularly to the people
who work with the radiation or ...), size, ...
- Maybe pasteurization
- What would Weinberg (Can Technology Shape Social Engineering) want
you to consider as you assess these technologies?
- Move on to Group B questions.
- What would Whittaker want you to consider as you assess these
- Do people think about the technology? Some do, but often hidden.
- Is there still an niche for raw milk?
- Why do powdered eggs exist?
- What would Florman (Technology and the Tragic View) want you
to consider as you assess these technologies?
- Move on to Group C questions.
- What would Petroski say about these technologies?
- Petroski is all about risks
- But he might be more cautious with relationship to food
"You have to trust your food."
Liability with consumers and food.
- What would Pool (How Society Shapes Technology) want you to
consider as you assess these technologies?
- Move on to Group A questions.
