New media have changed the parameters of public relations, multiplying audiences and altering the nature of relationships. Practitioners’ ethics approaches have been slower to adapt, frequently proving inadequate to the changes. McLuhan’s theory of technological determinism predicts this lag in conceptualizing and adapting to technological evolution; with awareness of the problem, however, practitioners have an opportunity to consciously shift to using the potential of new media proactively for ethical guidance, rather than continuing to allow ethics processes to lag behind technological (...) capacity. -/- In 1967 Marshall McLuhan wrote, “When faced with a totally new situation, we tend always to attach ourselves to the objects, to the flavor of the most recent past” (74). His words referred to the gap he observed between the potentially innovative functionality of new media, and the predominately traditionalist approaches to their use. While McLuhan’s comments are now more than 40 years old, and a host of newer technologies has evolved from those he described, his point remains strikingly germane: This chapter demonstrates that there is still a chasm between the potential and the utilization of new media, and explores the implications of that chasm for the specific context of new media and ethics in the field of public relations.

The operational definition of a weak value for a quantum mechanical system involves the limit of the weak measurement strength tending to zero. I study how this limit compares to the situation for the undisturbed system. Under certain conditions, which I investigate, this limit is discontinuous in the sense that it does not merge smoothly to the Hilbert space description of the undisturbed system. Hence, in these discontinuous cases, the weak value does not represent the undisturbed system. As a result, (...) conclusions drawn from such weak values regarding the properties of the studied system cannot be upheld. Examples are given. (shrink)

Even after multiple cycles of ABET accreditation, many engineering programs are unsure of how much curriculum content is needed to meet the requirements of ABET’s Criterion 3.f (an understanding of professional and ethical responsibility). This study represents the first scholarly attempt to assess the impact of curriculum reform following the introduction of ABET Criterion 3.f. This study sought to determine how much professional and ethical responsibility curriculum content was used between 1995 and 2005, as well as how, when, why, and (...) to what effect changes in the amount of content occurred. Subsequently, the study sought to evaluate if different amounts of curriculum content generated differing student outcomes. The amount of curriculum content used by each of the participating programs was identified during semi-structured interviews with program administrators and a review of ABET Self-Study documents. Quantitative methods were applied to determine if a relationship existed between the curriculum content and performance on a nationally administered, engineering-specific standardized examination. The findings indicate a statistical relationship, but a lack of structure between the amount of required content in the curriculum and performance on the examination. Additional findings were also generated regarding the way that programs interpret the Criterion 3.f feedback generated during accreditation visits. The primary impact of this study is that it dispels the myth that more courses or course time on professionalism and ethics will necessarily lead to positive engineering education outcomes. Much of the impetus to add more curriculum content results from a lack of conclusive feedback during ABET accreditation visits. (shrink)
