Galloway, Jr. 6 Issue Dedication Features 8 Ethics in Business: Every Employee’s Character and Behavior Count Chad Holliday All employees must think about how their work impacts society, the environment, and the safety of coworkers. 15 Protecting Dissent in Organizational Contexts Thomas W. Smith III and Tara L. Hoke Organizational culture must respect and facilitate dissent to ensure that engineering professionals comply with their ethical obligations. 21 Engineering Society Codes of Ethics: A Bird’s-Eye View Arthur E. Schwartz Engineering societies play a critical role in providing practical ethical guidance to engineers. 27 Engineering Codes of Ethics: Legal Protection for Engineers Jeffrey H. Matsuura Engineers can use codes of ethics to preserve their personal legal rights and reduce their risk of personal legal liability. 30 Beyond Protecting the Public from Risk Robert B. Gilbert Engineers can better serve the public by considering costs and benefits in addition to failure, and by working more closely with the public. 36 How Some Scientists and Engineers Contribute to Environmental Injustice Kristin Shrader-Frechette Flawed or misused analytic techniques for assessing pollution risk can allow environmental injustice, disproportionate health harm to children and to poor or minority communities. 45 Ethical Implications of Computational Modeling Kenneth R. Fleischmann and William A. Wallace Modelers must consider decisions from multiple perspectives, to take account of both their own values and those of their users.

Henry Corruption in engineering/construction is an important problem that national and international resources are available to combat. 59 Can Engineering Ethics Be Taught? Deborah G.

Society, University of Virginia Over the last few decades the engineering community has taken steps to better address ethical issues and to establish a climate supportive of ethical behavior. The Accrediting Board for Engineering and Technology (ABET) and professional licensing organizations have included ethics education as a requirement on the path to graduation and professional preparation as well as a prerequisite in continuing professional development.
