Engineering ethics is attracting increasing interest in engineering universities throughout the nation. At Texas A&M University, evidence of this interest in professional ethics culminated in the creation of a new course in engineering ethics, as well as a project funded by the National Science Foundation to develop material for introducing ethical issues into required undergraduate engineering courses. A small group of faculty and administrators actively supported the growing effort at Texas A&M, yet this group must now expand to meet the needs of increasing numbers of students wishing to learn more about the value implications of their actions as professional engineers.
The increasing concern for the value dimension of engineering is, at 1east in part, a result of the attention that the media has given to cases such as the Challenger disaster, the Kansas City Hyatt-Regency Hotel walkways collapse, and the Exxon oil spill. As a response to this concern, a new discipline, engineering ethics, is emerging. This discipline will doubtless take its place alongside such well-established fields as medical ethics, business ethics, and legal ethics.
The problem presented by this development is that most engineering professors are not prepared to introduce literature in engineering ethics into their classrooms. They are most comfortable with quantitative concepts and often do not believe they are qualified to lead class discussions on ethics. Many engineering faculty members do not think that they have the time in an already overcrowded syllabus to introduce discussions on professional ethics, or the time in their own schedules to prepare the necessary material. Hopefully, the resources presented herein will be of assistance.
Engineering ethics is a compulsory subject in every institute of science and technology in the United States.

(二)66Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case. The ridge (隆起) structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original pattern.67Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take. Finger-prints can be made very easily with printer's ink. They can by be recorded easily.68Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain.69. When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye.70Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.
F. His finger-prints can prove who he is even if his appearance has been changed by age or accident. G. Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. |
