Notes from SA

  1. Some of the metrics for risk - Dread or lack thereof, Knowledge, Analyze, Severity

  2. Some of the broad categories of technology that Lyons introduced were:

a. Nanotechnology

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.

  1. 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.

  2. Pool (How society shapes technology) would want us to think about fads in food, nutrition, and health as we assess new technologies about food.

  3. 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 broad categories of technology that Lyons introduced?

What are other issues Lyons considered?

What are some particular technologies within each category that Lyons introduced?

Applying lenses: Small Group

Technologies to think about:

Group A:

Group B:

Group C:

Applying lenses: Big Group

Why differences?
