An approach to integrating “professional responsibility” in engineering into the capstone design experience

ABET 2000 Criteria encourages development of proficiency in professional responsibility in engineering as part of the undergraduate curriculum. This paper discusses the use of industrially sponsored capstone design projects to encourage active discussion of professional responsibility in engineering that naturally occurs during the engineering design process. The paper also discusses student participation in designing responses and approaches to issues such as engineering ethics. The paper includes specific examples of topics addressed by students and the approaches developed (by students) in addressing these issues. An earlier version of this paper was presented at the International Conference on Ethics in Engineering and Computer Science, Case Western Reserve University, Cleveland, March 21–24, 1999.     

Evolution: Journey or Random Walk?

Though early ideas of evolution saw it as progressive, most modern theories see it as a random walk. The theories of Richard Dawkins, Stephen Jay Gould, Edward O. Wilson, Stuart Kauffman, Steven Rose, and Robert Wesson are surveyed, showing their agreement on the fact of evolution but not on the mechanism. Evolution is an incomplete theory. Any theology should therefore be based only on its broadest features. Generally, evolution is the development of complex forms from simple ancestors. Within a Christian context, it can be seen as a journey toward the unification of all things in Christ, the ultimate complexity.     

What do the MMPI-2 restructured clinical scales reliably measure? Answers from multiple research settings

The Restructured Clinical (RC; Tellegen et al., 2003) scales were developed to improve measurement of the core constructs of the MMPI-2 (Butcher et al., 2001) Clinical scales by removing "demoralization," hypothesized to affect these scales adversely. Using 25 samples with MMPI-2 responses from 78,159 subjects across diverse clinical settings, we found that each RC scale was highly correlated with a Supplementary, Content, or Personality Psychopathology 5 (PSY-5; Harkness, McNulty, & Ben-Porath, 1995) scale: higher, in fact, than the correlation between the RC scale and its parent scale. Furthermore, for over half the RC scales (i.e., RC1, RC3, RC7, RC8, and RCd), the correlations were strong enough to conclude that the RC scales replicate MMPI-2 scales with rich empirical foundations; the remaining RC scales were not redundant. Next, we examined reliability estimates using alpha coefficients and interitem correlations and did not reveal superior reliability for most of the RC scales over existing MMPI-2 scales.     

Is there an evolutionary advantage of schizophrenia?

Schizophrenia is a universal disorder with strongly genetic aetiology. A constant prevalence rate, universally, in the face of reduced fecundity leads to the argument here that an evolutionary advantage exists, but not solely for schizophrenia. Possible areas of advantage are examined and it is argued that schizophrenia exists as a costly trade-off, in the evolution of Homo sapiens, as a by-product of a yet unknown uniquely human quality. The reason it has stayed in existence is due to a combination of advantages bestowed upon the kin, the group and, to a lesser extent, individuals who suffer from the disorder; these all contribute a different type of advantage, each of which alone would not be sufficient. Further, the evidence for the other advantages alone lack the rigour of evidence seen in the by-product theories, which provide as yet unparalleled comprehensive evolutionary evidence.     

WHAT IS PURE,WHAT IS GOOD? DISINTERESTEDNESS IN FÉNELON AND KANT

Two philosophers, Robert Spaemann and Henri Gouhier, have identified a similarity between Fénelon and Kant in the prominence of motive in their thought: disinterestedness in Fénelon's pure love and in Kant's good will . Spaemann emphasizes their common detaching of the ethical in terms of motivation from the context of happiness. In this article I explore further similarities and differences under the topics of perfectionism, pure love, good will, happiness, and disinterestedness, as these are pertinent to their thought. On perfectionism there appears a stark contrast; on pure love over against good will, on happiness, and on disinterestedness, however, there seems a balance between likenesses and differences. Finally I point out a qualification set on pure love by Fénelon and on the good will by Kant.     

Comparing Democrats and Republicans on Intrinsic and Extrinsic Values

Although claimed differences in values have played a prominent role in recent U.S. politics, the value systems of typical Republicans and Democrats have not been evaluated within a relevant dimensional framework. In 4 studies, party members were compared on extrinsic (money, popularity, image) and intrinsic (intimacy, helping, growth) values. Republicans were consistently higher on extrinsic relative to intrinsic values, a pattern suggested by past research to be personally and socially problematic. In Study 4, Republicans were also lower in a different measure of prosocial values, derived from social-dilemma research. All studies found an interaction such that only nonreligious Republicans were lower than Democrats on the intrinsic value of helping needy others. Implications for contemporary political discourse are discussed.     

Exploration of the Factor Structure of ADHD in Adolescence through Self,Parent, and Teacher Reports of Symptomatology

Factor analytic studies of attention-deficit/hyperactivity disorder (ADHD) in children and adults have shown that second-order and bifactor models better represent ADHD symptoms than two- or three-factor models, yet there is far less evidence for a bestfitting model of ADHD in adolescence. Thus, the current study examined the factor structure of ADHD in adolescence and further evaluated the external validity of the best fitting model. Participants were 588 adolescents (22 % female; 366 with a childhood ADHD diagnosis; mean age 15.9 years) from the 8-year assessment of the Multimodal Treatment Study of Children with ADHD (MTA). ADHD symptoms were assessed via adolescent self-report, parent report, and teacher report on the SNAP-IV scale. Potential factor structures for the 18 symptoms of ADHD were tested for each informant, which included traditional one-factor, two-factor, and three-factor models of ADHD, as well as second-order factor (specific factors loading onto general factor) and bifactor (items loading onto both specific and general factors) models. Unique associations between external criteria and the identified factors of each informant’s best fitting model were examined. Although several of the proposed models exhibited good fit, the second-order two-factor model best accounted for ADHD in adolescence according to self-report and parent report, and the second-order three-factor model was optimal according to teacher report. Several key measurement issues emerged for the hierarchical bifactor models, such as numerous Heywood cases and out-of-bound parameter estimates, which rendered them unfit as optimal representations of ADHD in adolescence. These findings and the implications of the best fitting model of ADHD in adolescence suggest that a possible reorganization of this disorder may eventually aid clinicians in the accurate diagnosis of ADHD in adolescents.     

Should Genetic Testing be Offered for Children? The Perspectives of Adolescents and Emerging Adults in Families with Li-Fraumeni Syndrome

Whether children should be offered genetic testing for cancer risk is much debated but young voices are rarely heard in these conversations. The current study explored perspectives of genetic testing held by adolescents and emerging adults in families with Li Fraumeni syndrome (LFS). Twelve 12- to 25-year-olds in families with LFS completed qualitative interviews for this study. All believed that testing should be offered for children but many qualified this statement saying parental approval would be needed and testing should be optional. Genetic testing was seen as way to learn of risk status, allow for disease prevention efforts, and reduce uncertainty and anxiety. Perceived disadvantages included negative emotions associated with the testing result. Participants generally felt that children should be involved in the testing decision, but that parents could unilaterally decide to have a child tested in certain circumstances (e.g., young age, high risk). All who were aware of having been tested and of their test result (n = 7; 4 positive) said testing had no negative impact on their outlook and they agreed with the decision to undergo testing. Implications of these findings for clinical practice and future research are discussed.
