2. Administrative • Today - distribute m.c. answers from exam 2 • versions of better/worse 10 pt. Answers • criteria used for the grading • Wednesday • Lecture 25 - Do statistics lie? • Friday • last lecture - Decision making: how to we get supporting evidence? • Monday • review for final & return papers 2

3. a) Politics of Technology: • mention and discussion of the following elements got full points, • order • membership • power • freedom • partial answer got 1/2 of the points • b) Innovations: • Mentions the clinic as the innovation for credit.…some mentioned "relocation of the clinic" as an innovation (not as good). • The best answers mentioned the clinic as the innovation and went further to describe the non-linear model of innovation. • c) Ethics: • Mention the need to use a model to aid in assessing and making decisions about the existing situation. Some mentioned 'an ethical dilemma', but few took it a step further to integrate class materials (if you could have written the same answer without attending class, you probably didn't score as high). 3

4. d) Laws: • Mention of minimum requirements being met, but not always enough to protect the people. May mention and discussion of limitations of tort and/or contract law (tying it together to describe what might be limits for what the residents have the power to do, given their dissatisfaction). • e) What's the problem? • virtually everyone got these 2 points. • f) Better to place near your home? Why/why not? • Virtually everyone got full points for this one. However, in some cases, those who had the best answers for the other parts of this question were careless and left this out or did not give a justification. 4

5. Today • Finish technology at Work • tutorial - Labor and Technology - online. • Charlie Chaplin Video - Modern Times • 1936 • QOTD 5

6. Labor and Technology • video - Modern Times - Charlie Chaplin • 18th century - Factories • labor shift into factories • mechanization, many people needed at 1 site • however, no longer need as many highly skilled people to make things • factories located near streams and rivers- power 6

7. Mass Production and Line-Assembly • First - Henry Ford - Ford Auto - Model T • A car for the masses • inexpensive, simple and easy to make • Produce millions to allow cheaper prices • began with a series of experiments • first, a rope, 250 feet long, a car chassis was pulled • 140 assemblers, 150 ft. line; 177 assemblers, 300 ft line • time to produce a car reduced from 12.5hrs to 6hr to 3hrs to eventually only 93 min/car 7

8. The new factory included • special purpose tools • centralized decision making • standardized parts - interchangeable • large sheet metal stamping tools (presses) • 1915 - 500,000 cars/year (Detroit, Michigan) • 1919 - 800,000 cars/year (River Rouge, Ford) • 1923 2,000,000 cars/year (River Rouge, Ford) • ‘optimizing’ worker performance • time and motion analysis • workers timed with stop watch and unnecessary motions were eliminated 8
