Three myths about codes of engineering ethics

A myth is a story or belief that is truer to fear or wish than to fact. My subject is three myths which are common in engineering ethics: (a) that the earliest codes of engineering ethics put loyalty to one's client or employer ahead of the public interest; (b) that engineering codes of ethics should be mere (moral) guidelines rather than (legalistic) rules; and (c) that codes of engineering ethics are too vague to provide much guidance. Perhaps the only thing that these myths have in common is that they are all too common in discussions of engineering ethics, but I think they have more in common than that - they seem to be mutually enforcing     

Teaching of ethics in biomedical engineering

The teaching of ethics in biomedical engineering is discussed with particular reference to the teaching of ethical principles in the B.S. Biomedical Engineering program at Louisiana Tech University. Consideration is given to such issues as organ transplantation and artificial organs, conducting research in new biomedical technology, the costs of health care, and developing and regulating new technology

探讨以外径为φ7mm或φ9mm的铜管做基管,配以三种不同宽度尺寸的铝箔为外肋片的冷凝器,即三种规格型号的冷凝器:21.65mm铝箔对应φ9mm铜管,12.7mm或18.19mm铝箔对应φ7mm铜管,将它们分别装入在同一系统(蒸发器和压缩机相同)中,通过试验比较它们的性能。根据实验和数据的结果,总体上φ7mm的冷凝器较φ9mm的制冷性能更优,并且成本更低。     

Teaching engineering ethics to non-engineering students

Because engineering decisions regarding infrastructure and consumer products affect everyone, students enrolled in non-engineering curricula can also benefit from examining issues of engineering ethics. The article explores methodologies and topics for acquainting non-engineering students with engineering ethics, including a short background of a professional ethics course     

Teaching engineering ethics in the United States

The present academic discipline of engineering ethics originated in the mid-1970s when engineering and philosophy professors began to consider ethical problems facing engineers. In addition to the role played by these two primary disciplines, disciplines such as law, history, behavior and management sciences, and religious studies shaped the emerging field, as did parallel developments in other applied ethics fields treating professional responsibility, such as medical, legal, and business ethics. Courses in engineering ethics were developed at a number of universities. In addition to stand-alone courses in engineering ethics, many universities incorporated ethical components into technical or nontechnical courses. The article summarizes significant developments at a number of top engineering schools in the US, spurred in part by National Science Foundation funding. In addition, a spring 1997 search of the World Wide Web uncovered developments at a wide range of universities and colleges. Not all schools provide information on the Web. In addition, information on the Web is constantly changing and Web searches are imperfect. Nevertheless, the information provided here gives a good picture of the kinds of initiatives in engineering ethics pedagogy that now exist     

Using history and sociology to teach engineering ethics

An overview is given of the academic discipline of engineering ethics in the United States, describing how the subject has been taught in the US, and suggesting a new method that uses the history and sociology of science and technology to teach ethical issues in engineering. Traditionally, engineering ethicists have focussed on accidents to analyze both ethical conduct and social implications of engineering. The new approach attempts to move beyond this concern with what might be called disaster ethics to study the ethical and social aspects of everyday engineering practice     

三种铅蓄电池检测仪的使用效能比较

对铅蓄电池的在线状态可靠性检测是铅蓄电池维护的关键技术。现在有三种检测方法,一是电导内阻检测法,就是用电导仪测量铅蓄电池的内阻,根据内阻的相对变化,对电池的性能做出判断。二是采用负载电压法,就是给被测电池施加足够大的负载,测量其负载能力CB值。三是用恒流放电的检测仪对铅蓄电池组进行放电,根据放出的容量判断电池是否合格。本文就三种检测仪的具体检测数据做以对比分析,结果表明负载电压的CB检测法优于其他两种方法。     

Learning from failure: terrorism and ethics in engineering education

Engineers strive for safety. This has been true for all of engineering's history. The issue in question is not whether engineers value safety, but rather how safety is defined, what its limits are, and who is responsible for ensuring it. The answers lie in the context rather than the technology of design. The events of September 11th are, like the disasters before them, the latest in a series of crises stirring discussion of the meaning of safety and responsibility. What remains to be seen, in the wake of the terrorist attacks, is whether the disasters of that day will be sufficient to cause not only a rethinking, but a reshaping of the primary canon of engineering ethics-that engineers' first and foremost obligation is to hold the public safety paramount. Whatever we take to be the lessons of September 11th for engineering design, there is an important lesson for engineering education. As we rethink the meaning of ethics codes, we must also rethink the meaning of our educational goals. The terrorist attacks may well require expansion from preventing failures that result from "human fallibility" toward also preventing failures that result from human maliciousness. What will not change is humans' essential role in engineering; technology, by definition, cannot exist without human intervention. Both the cause and prevention of technological failures must therefore rest in human hands as well, and our students require and deserve the broad education necessary to cope with this reality.

Explaining disasters: the case for preventive ethics

In 1986, the space shuttle Challenger exploded during launch, taking the lives of six astronauts and one teacher. The disaster virtually stopped U.S. space exploration for two years. How should this disaster be explained? The article discusses three types of explanation and considers the application of preventive ethics. People should be informed about unusual dangers to which they might be subjected, and given the chance to consent or not consent to the dangers     

Engineering ethics cases for electrical and computer engineeringstudents

Rarely is electrical technology at the focus of the classic case studies used in engineering ethics courses and textbooks. This makes it sometimes difficult to excite and to motivate electrical and computer engineering students to study and discuss these cases. In teaching engineering ethics to these students, it can be valuable to employ case studies that involve technical issues that electrical and computer engineers have already studied in other courses. In this paper, four engineering ethics case studies covering topics that have been shown to interest electrical and computer engineering students are presented
