Ethics, Engineers and Drama

This paper describes four plays which illustrate ethical themes relevant to engineers and which could be used as a resource for engineers who wish to explore ethical topics and their relationship with professional practice. The plays themselves have been chosen because a character in the play is involved in engineering activities. Each play is analysed to highlight some of the ethical issues the play raises. Often ethical topics are presented in abstract terms but the plays relate ethical issues to individuals and individual actions in specific situations that connect either directly or figuratively to practical situations engineers find themselves in. The paper describes how the resources have or could be used in an educational programme.     

Functions and Health at the Interface of Biology and Technology

Synthetic biology promises to eliminate the distinction between biology and engineering by delivering a philosophically interesting new kind of entity: a biological organism that is wholly designed and constructed by humans. The possibility of such organisms raises interesting questions in three domains: the analysis of (1) biological functions, (2) engineering functions, and (3) health and disease. This paper identifies and systematically answers these questions. This does not only establish how we should think about functions and health and disease in synthetic biological organisms, but it also reveals insights that are of broader relevance: (1) aetiological accounts of biological function need to omit or reinterpret reference to natural selection. This results in complete continuity between aetiological analyses of function in engineering and philosophy; (2) considering synthetic biology prompts interesting further questions about heritability, ancestry, and biological individuals; and (3) accounts of disease as biological dysfunction do not straightforwardly map onto our intuitive health and disease judgments regarding non-human animals. In response to the latter point I examine three possible avenues, and tentatively defend one on behalf of the ‘disease as dysfunction’ theorist.     

PRiME: Integrating professional responsibility into the engineering curriculum

Engineering educators have long discussed the need to teach professional responsibility and the social context of engineering without adding to overcrowded curricula. One difficulty we face is the lack of appropriate teaching materials that can fit into existing courses. The PRiME (Professional Responsibility Modules for Engineering) Project (http://www.engr.utexas.edu/ethics/primeModules.cfm) described in this paper was initiated at the University of Texas, Austin to provide web-based modules that could be integrated into any undergraduate engineering class. Using HPL (How People Learn) theory, PRiME developed and piloted four modules during the academic year 2004–2005. This article introduces the modules and the pilot, outlines the assessment process, analyzes the results, and describes how the modules are being revised in light of the initial assessment. In its first year of development and testing, PRiME made significant progress towards meeting its objectives. The PRiME Project can strengthen engineering education by providing faculty with an effective system for engaging students in learning about professional responsibility. An earlier version of this paper was presented at the 2005 conference, Ethics and Social Responsibility in Engineering and Technology, Linking Workplace Ethics and Education, co-hosted by Gonzaga University and Loyola Marymount University, Los Angeles, CA, USA, 9–10 June 2005.

Engineering Ethics and Identity: Emerging Initiatives in Comparative Perspective

This article describes and accounts for variable interests in engineering ethics in France, Germany, and Japan by locating recent initiatives in relation to the evolving identities of engineers. A key issue in ethics education for engineers concerns the relationship between the identity of the engineer and the responsibilities of engineering work. This relationship has varied significantly over time and from place to place around the world. One methodological strategy for sorting out similarities and differences in engineers’ identities is to ask the “who” question. Who is an engineer? Or, what makes one an engineer? While engineering ethics has attracted little interest in France and formal education in the subject might be seen as redundant, German engineering societies have, since the conclusion of World War II, demanded from engineers a strong commitment to social responsibility through technology evaluation and assessment. In Japan, a recent flourishing of interest in engineering ethics appears to be linked to concerns that corporations no longer function properly as Japanese “households.” In each case, deliberations over engineering ethics emerge as part of the process through which engineers work to keep their fields in alignment with changing images of advancement in society.     

Longitudinal relations of self-efficacy to outcome expectations, interests, and major choice goals in engineering students

We examined the nature of the temporal relations among the core person variables in the social cognitive model of academic and career choice [Lent, R. W., Brown, S. D., & Hackett, G. (1994). Toward a unifying social cognitive theory of career and academic interest, choice, and performance [Monograph]. Journal of Vocational Behavior, 45, 79-122.]. Participants were 209 students taking beginning level engineering courses at either a predominantly White or a historically Black university. They completed measures of self-efficacy, outcome expectations, interests, and goals near the end of two consecutive semesters. Path analyses indicated support for a model in which self-efficacy served as a temporal precursor of outcome expectations, interests, and goals. There was less support for a model in which the latter variables produced reciprocal paths to self-efficacy. Implications for future longitudinal research on SCCT’s (social cognitive career theory’s) choice hypotheses are discussed.     

The identification and transfer of timesharing skills

Performance on two different task combinations was examined for evidence that timesharing skills are learned with practice and can transfer between task combinations. One combination consisted of two discrete informaion processing tasks, a short-term memory task and a classification task; the other consisted of two identical one-dimensional compensatory tracking tasks. Three groups of 16 subjects were employed in the experiment. The first received dual-task training on both combinations; the second received single-task training on the discrete-task combination and dual-task training on the tracking combination; the third received dual-task training on the tracking combination only. Evidence for distinct timesharing skills was found in both combinations using a new technique designed to separate improvements in timesharing skills from improvements in single-task performance. Transfer of timesharing skills also was found. Several fine-grained analyses performed on the data from the discrete task combination and a Control Theory Analysis of the tracking data indicated that skills in parallel processing were learned in each combination and transferred between them.     

Personality types and motivational characteristics of academics versus professionals in industry in the same occupational discipline

The present study suggests that individuals belonging to different job categories—academics versus professionals in industry—differ in personality types and in motivational characteristics even though they are of the same occupational discipline. Subjects were 49 academics and 45 professionals in industry of two disciplines: engineering and management sciences. Holland's 6 personality types and 18 motivational characteristics measured in terms of Vroom's expectancy theory of motivation were used as the discriminant variables. Results indicate that academics are discriminated from professionals in industry by scoring significantly higher on the Artistic type and significantly lower on the Enterprising type even when the discipline is controlled. The distinction between the two groups is much deeper when motivational factors are examined: Academics are motivated by the opportunity for scientific contribution, for autonomy, and for the high status attained in their job. By contrast, professionals in industry are highly motivated by the opportunity for exercising power.
