  • Human Rights As a Lens for Engineering Ethics?
    Paper ID #26018 Human Rights as a Lens for Engineering Ethics? Dr. Angela R. Bielefeldt, University of Colorado, Boulder Angela Bielefeldt is a professor at the University of Colorado Boulder in the Department of Civil, Environ- mental, and Architectural Engineering (CEAE). She has served as the Associate Chair for Undergraduate Education in the CEAE Department, as well as the ABET assessment coordinator. Professor Bielefeldt was also the faculty director of the Sustainable By Design Residential Academic Program, a living- learning community where interdisciplinary students learn about and practice sustainability. Bielefeldt is also a licensed P.E. Professor Bielefeldt’s research interests in engineering education include service- learning, sustainable engineering, social responsibility, ethics, and diversity. c American Society for Engineering Education, 2019 Human Rights as a Lens for Engineering Ethics? Abstract This paper illustrates how the United Nations Universal Declaration of Human Rights can be used to frame engineering ethics discussions. Examples are provided for how engineering ethics relates to the rights to: nondiscrimination, life and security of persons, privacy, property ownership, work, and a basic standard of living. The recent Statement on Scientific Freedom and Responsibility from the American Association for the Advancement of Science was rooted in the right to science and recognizes the important link between freedom and responsibility. This philosophy includes attention to the broader impacts of research activities and argues against higher education tenure and promotion criteria that preference self-serving academic outcomes over real-world benefits and engagement. The practices of engineering education itself are probed in relation to Article 26 on the right to education, in terms of accessibility and promoting peace.

  • Business and Engineering Ethics – Similarities, Differences and Challenges
    Ljerka Tomljenović Polytechnic of Rijeka, Croatia E-mail: [email protected] Anita Stilin Polytechnic of Rijeka, Croatia E-mail: [email protected] Saša Hirnig Polytechnic of Rijeka, Croatia E-mail: [email protected] BUSINESS AND ENGINEERING ETHICS – SIMILARITIES, DIFFERENCES AND CHALLENGES JEL classification: M19 Abstract Issues of applied ethics and its influence on the behaviour of people in the wider social context have been investigated from many different aspects. The aim of this paper is to clarify the fundamental differences and similarities between business and engineering ethics, determine the areas which represent potential source of conflict and explore specific ethical dilemmas that occur with individuals who are engaged in the engineering profession in the business surroundings. Previous research lacks agreement. Practice has proved that the ethical dilemmas are integral part of engineering work due to various challenges such as: relationship between quality and safety, quality and costs, safety and costs; intellectual property issues, etc. Considering that in most cases engineers are employed by business subjects who adopt economic principles, engineering and business aspects of engineering decisions are inseparable. The empirical part of the paper will consist of research of the engineer’s attitudes referring to: different domains of engineering in which ethical issues arise, conditions at work associated with ethical issues; common difficulties encountered and the level of support ensured by firm in dealing with ethical dilemmas, and the attitude toward engineering ethics as professional ethics. Theoretical and empirical research are expected to give an evaluation of key areas that determine the ethical challenges faced by engineers and open questions about BUSINESS ETHICS 58 guidelines that will assist in solving specific engineering ethical dilemmas.

  • Ethical Issues in the Global Arms Industry
    draft: March 7, 2015 Michael Davis, Illinois Institute of Technology Ethical Issues in the Global Arms Industry: A Role for Engineers Ethical Dilemmas in the Global Defense Industry Conference University of Pennsylvania Law School Philadelphia, April 16, 2015 This paper has four parts. The first two seek to clarify the subject of this conference, ethical issues in the global arms industry. The third sketches the role engineers have in much of the global arms industry. The last part considers one way that engineers might help with resolving some of the industry’s ethical issues. While the first part of this paper should contain few surprises, the last three will, I hope, contain more. 1. Dilemmas and Defense Let me begin with two differences between the official title of this conference and the title of my paper. First, I have substituted “issues” for “dilemmas”. Second, I have substituted “arms” for “defense”. The purpose of these changes is to avoid unnecessary disputes rather than to change the subject of the conference. Let me explain. A “dilemma” is a situation in which a difficult choice has to be made between two (or more) equally undesirable alternatives.1 If the alternatives were not equally undesirable, the choice would be easy: choose the more desirable alternative. There would be no dilemma (though the choice might, like most good choices, have its cost). My impression is that the main ethical issues, questions, problems, or quandaries posed by the global arms industry are not dilemmas (in this sense) but complex situations in which most of the choices on offer are hard to assess and many of the best choices have yet to be devised.

  • New Ethical Challenges for Today Engineering and Technology
    New Ethical Challenges for Today Engineering and Technology Josep M. Basart Engineering School Universitat Autònoma de Barcelona (08290) Cerdanyola del Vallès Catalonia (Spain) [email protected] +34 935 812 167 Mireia Farrús N-RAS Research Centre Universitat Pompeu Fabra (08018) Barcelona Catalonia (Spain) [email protected] +34 935 421 118 Montse Serra Computer Science, Telecommunication and Multimedia Dept. Universitat Oberta de Catalunya (08018) Barcelona Catalonia (Spain) [email protected] +34 933 263 744 Abstract This paper is about the intersection of three related areas: ethics, gender and the field of engineering. It is important to focus on the attitudes and values woven through this intersection because they become essential for the complete development of the moral life of the engineering profession and of the awareness of the fact that this is a profession made up of both male and female professionals. Thus, specific behaviour coming from the feminine part is necessary in order to contribute to enriching the features of the engineering profile. An approach particularly attached to feminine values, in comparison to the masculine perspective, is a sign of commitment rather than rights, a collective social group rather than the individual and of an ethic based on caring for others rather than the traditional rationalistic arguments. Because of this, the introduction of qualitative diversity within this professional field is an important fact to highlight when women contribute to the engineering community through the enrichment, expansion and transformation of the values and attitudes that are predominant in the people who work and/or study within the area of engineering and technology.

  • Applying the Rules of Just War Theory to Engineers in the Arms Industry
    Science and Engineering Ethics (2006) 12, 685-700 Applying the Rules of Just War Theory to Engineers in the Arms Industry Aaron Fichtelberg Department of Sociology and Criminal Justice, University of Delaware, USA Key Words: Engineering Ethics, Just War Theory ABSTRACT: Given the close relationship between the modern arms industry and the military, engineers and other professionals who work in the arms industry should be held accountable to the principles of just war theory. While they do not deploy weapons on the battlefield and are not in the military chain of command, technical professionals nonetheless have a moral duty to abide by principles of jus ad bellum and jus in bello. They are morally responsible both for choosing the companies that employ them (and to whom these companies sell arms) and a well as what types of arms they develop. While there has been a great deal of discussion about the changes that America’s new war on terrorism will bring on the nature and morality of warfare, there are a number of lingering issues from the previous global conflict: the cold war rivalry between the United States and its now vanquished rival, the Soviet Union. One consequence of the last war which has gone without much comment from professional military ethicists,a is the formation of a large-scale, permanent military industry designed to support American and foreign militaries.b The budget of the US Department of Defense for the 2004 fiscal year was approximately 400 billion dollars. It dwarfs almost any other expenditure by the federal government, including $68.7 billion in procurement alone (even in a time of massive budget deficits, the procurement budget increased by $6.7 billion in 2003 dollars from the preceding year.)2 Arms manufacturers in the United States, largely comprised of engineers and other highly trained technicians, supply a.

  • Ethics and Ideology in Engineering Curricula
    Ethics and Ideology in Engineering Curricula Author: Rui M. L. Ferreira, IST, Technical University of Lisbon, Av. Rovisco Pais, 1049-001 [email protected] Abstract Engineering ethics is becoming a particularly valorised course in engineering curricula. Applied ethics educators in Anglo-Saxon universities often defend the case-study approach as the most effective way to introduce students to real-world ethical problems. In this text is pointed out that teaching engineering ethics involves constituting individuals as a social/professional group and, in that sense, is ideology conveying. The main concern addressed in this text is that engineering schools are not supplying students with the means to understand to role of ideology in the way they perceive, experience and act upon the world. Some emphasis is given on the analysis of synthetic case-studies in order to show that the case-study approach may overlook important issues concerning the production of reality. By recalling that there is no practice except by and in an ideology, it is concluded that the case-study approach is not ideology-free but embedded in the material existence of an ideological apparatus, in the sense of Althusser. It is claimed that unless these ideology-related problems are discussed in classrooms, topic h) of the accreditation criteria of ABET, “…the engineer must have… the broad education necessary to understand the impact of engineering solutions in a global/societal context;”, mirrored in many countries, is not being properly addressed.

  • Engineering Ethics and Computer Ethics: Twins Separated at Birth? Brian M
    Techné 8:1 Fall 2004 O’Connell & Herkert, Twins Separated at Birth? / 36 Engineering Ethics and Computer Ethics: Twins Separated at Birth? Brian M. O’Connell Central Connecticut State University Joseph R. Herkert North Carolina State University Over the past two decades, engineering ethics and computer ethics have emerged as identifiable fields of applied ethics. While some individuals have made contributions to both fields, for the most part they have developed in the USA along parallel, but separate paths. In previous presentations (O’Connell & Herkert 2001a; 2001b) we have argued that material drawn from computer ethics should be standard fare in all engineering ethics treatments, not just those aimed specifically at computer engineers and scientists. This conclusion emerges from the ever-expanding prominence of computer technology in both engineering education and practice and the form of engineered products. As noted by William Wulf (1997), a University of Virginia Professor and President of the National Academy of Engineering: The pervasive use of information technology in both the products and process of engineering…has the potential to change the practice of engineering significantly, and hence the education required to be an engineer…As the power of computers…increases exponentially, more and more routine engineering functions will be codified and done by computers, simultaneously freeing the engineer from drudgery and demanding a higher level of creativity, knowledge, and skill.

  • Ideologies of Engineering Education Introduction
    Part II Ideologies of Engineering Education Introduction Brent K. Jesiek and Christelle Didier Questions about the ideological underpinnings of engineering are not new, as evidenced by the efforts of a handful of pioneering historians and sociologists who dared tackle the topic. Edwin Layton’s classic The Revolt of the Engineers (Layton 1971), for example, showed how the professional ideals and aspirations embraced by many American engineers during the Progressive Era stood in marked tension with business imperatives and bureaucratic loyalty – and with the latter ultimately prevailing. Covering similar historical and conceptual territory but more Marxist in outlook, David Noble’s America by Design (1979) portrayed a growing alignment of the U.S. engineering profession with market capitalism and an almost mystical ideology of quasi-autonomous technology. Both works helped contextualize the profession’s development in America from the late nineteenth to mid-twentieth century and demonstrated how prevailing engineering values and attitudes were frequently interchangeable with a business ethos that was inculcated through domi- nant pathways of education and career development. Still other works have helped show how partially unique confi gurations of ideol- ogy and engineering have emerged in other national and cultural contexts, as refl ected in Ken Alder’s argument that the early modern history of the engineering profession in France was “energized by a radical ideology that justifi ed social hier- archy by reference to national service” (Alder 1999, p. xii).
