Chapter 1: What engineers do 1-1) Draw a conceptual sketch of your computer. Identify the keyboard, screen, power source, and information storage devices using arrows and labels.
Note: Eventually we will show you (if you don’t know already) how to draw a decently formatted sketch on your computer. Meanwhile this crude representation will suffice!

You are not so sure, though you cannot conclusively demonstrate a safety hazard. You request that a new safety analysis be done. Your supervisor denies your request on the grounds of time and limited budget. What do you do?)

1-13) Some American companies have refused to promote women into positions of high authority in their international operations in Asia, the Middle East, and South America. Their rationale is that business will be hurt because some foreign customers do not wish to deal with women. It might be contended that this practice is justified out of respect for the customs of countries which discourage women from entering business and the professions. Circuit Judge Warren J. Ferguson argued, however, that such practices are wrong. He ruled that gender stereotypes are not to be used in formulating job qualification, and that customer preferences do not justify gender discrimination. He added that while our legal system cannot be used to force other countries to stop gender discrimination, other countries cannot dictate gender discrimination for citizens of our country. Present and defend your view as to whether Judge Ferguson's ruling was justified. Most students will agree with the judge. However, they need to present some comments as to why they reached their conclusion. Your best approach is to write a short essay justifying your conclusions. Since your essay is your essay, there is no preferred answer to give you. Think it through and write a few paragraphs in clear and concise English supporting your opinion.

1-14) Marvin Johnson is Environmental Engineer for one of several local plants whose water discharges flow into a lake in a flourishing tourist area. Included in Marvin's responsibilities is the monitoring of water and air discharges at his plant and the periodic preparation of reports to be submitted to the Department of Natural Resources. Marvin has just prepared a report that indicates that the level of pollution in the plant's water discharges slightly exceeds the legal limitations. However, there is little reason to believe that this excessive amount poses any danger to people in the area; at worst, it will endanger a small number of fish. On the other hand, solving the problem will cost the plant more than $200,000. Marvin's supervisor says the excess should be regarded as a mere "technicality," and he asks Marvin to "adjust" the data so that the plant appears to be in compliance. He explains: "We can't afford the $200,000. It would set us behind our competitors. Besides the bad publicity we'd get, it might scare off some of tourist industry." How do you think Marvin should respond to Edgar's request?
a) Do what Edgar says b) Ask Edgar to join him in discussing this with Edgar’s boss c) Do not do what Edgar s says

a). Do what Edgar says

1-15) Derek Evans used to work for a small computer firm that specializes in developing software for management tasks. Derek was a primary contributor in designing an innovative software system for customer services. This software system is essentially the "lifeblood" of the firm. The small computer firm never asked Derek to sign an agreement that software designed during his employment there becomes the property of the company. However, his new employer did. Derek is now working for a much larger computer firm. Derek's job is in the customer service area, and he spends most of his time on the telephone talking with customers having systems problems. T his requires him to cross reference large amounts of information. It now occurs to him that by making a few minor alterations in the innovative software system he helped design at the small computer firm the task of cross referencing can be greatly simplified. On Friday Derek decides he will come in early Monday morning to make the adaptation. However, on Saturday evening he attends a party with two of his old friends, you and Horace Jones. Since it has been some time since you have seen each other, you spend some time discussing what you have been doing recently. Derek mentions his plan to adapt the software system on Monday. Horace asks, "Isn't that unethical? That system is really the property of your previous employer." "But," Derek replies, "I'm just trying to make my work more efficient. I'm not selling the system to anyone, or anything like that. It's just for my use -- and, after all, I did help design it. Besides, it's not exactly the same system -- I've made a few changes." What should be done about this situation?2
a) Derek should go ahead and make the adaptation b) Derek should suggest to his boss a meeting with the other company to discuss use of the program. c) Derek should drop the idea
Options Canons
a). Make the adaptation
b). Suggest a meeting
c). Drop the idea

1-16) Jan, a professional engineer on unpaid leave, is a part-time graduate student at a small private university and is enrolled in a research class for credit taught by Dimanro, a mechanical-engineering professor at the University. Part of the research being performed by Jan involves the use of an innovative geothermal technology. The University is in the process of enlarging its facilities, and Dimanro, a member of the University's building committee, has responsibility for developing a request for proposal (RFP) in order to solicit interested engineering firms. Dimanro plans to incorporate an application of the geothermal technology into the RFP. Dimanro asks Jan to serve as a paid consultant to the University's building committee in developing the RFP and reviewing proposals. Jan’s employer will not be submitting a proposal and is not averse to having Jan work on the RFP and proposal reviews. Jan agrees to serve as a paid consultant. Is it a conflict of interest for Jan to be enrolled in a class for credit at the University and at the same time serve as a consultant to the University? 3
a) Jan should assume a conflict of interest and drop the idea b) Jan should request a legal opinion as to the legality of this service c) Jan should go ahead and serve without inquiring further
