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.

Word learning and individual differences in word learning reflected in event-related potentials

Adults learned the meanings of rare words (e.g., gloaming) and then made meaning judgments on pairs of words. The 1st word was a trained rare word, an untrained rare word, or an untrained familiar word. Event-related potentials distinguished trained rare words from both untrained rare and familiar words, first at 140 ms and again at 400-600 ms after onset of the 1st word. These results may point to an episodic memory effect. The 2nd word produced an N400 that distinguished trained and familiar word pairs that were related in meaning from unrelated word pairs. Skilled comprehenders learned more words than less skilled comprehenders and showed a stronger episodic memory effect at 400-600 ms on the 1st word and a stronger N400 effect on the 2nd word. These results suggest that superior word learning among skilled comprehenders may arise from a stronger episodic trace that includes orthographic and meaning information and illustrate, how an episodic theory of word identification can explain reading skill.     

Reconstructing psychopathy: clarifying the significance of antisocial and socially deviant behavior in the diagnosis of psychopathic personality disorder

A survey of clinical views suggests that the significance of antisocial and socially deviant behavior in the diagnosis of psychopathic personality disorder is unclear. To investigate this issue, we evaluated Psychopathy Checklist-Revised ratings (PCL-R; Hare, 1991) using structural equation modeling. One model, referred to as the measurement model, included PCL-R ratings related to antisocial behavior as primary symptoms of psychopathy; a second, referred to as the causal model, included the same PCL-R ratings as secondary symptoms or consequences. Compared to the measurement models, the causal model included more PCL-R items, was more parsimonious, and had equal or superior fit indices. These findings suggest that antisocial behavior is best viewed as a secondary symptom or consequence of psychopathy, In addition, the findings have important implications for future research and clinical-forensic practice, especially concerning the assessment of risk for criminality and violence.     

Synchronized cortical potentials and wavelet packets: a potential mechanism for perceptual binding and conveying information

Temporal synchronization in neuronal assemblies has been linked to the functional roles of perceptual binding, sensory-motor integration, attention, and information coding. We report new evidence for a common underlying mechanism that uses specific temporal patterns of synchronized neuronal activity as a basis for conveying information. The temporal patterns of stimulus-related synchronized neuronal discharges are structured to closely resemble specific members of the Symlet wavelet packet family employed in a computational framework. Together, these results suggest that temporal patterns of synchronized activity may act as a parallel, distributed code for information through a mechanism computationally equivalent to wavelet packet analysis.     

Parental language and verbal responsiveness to children in crowded homes.

This article is a secondary data analysis of the University of Kansas Language Acquisition Project, which intensively studied, on a regular basis, parent and child language from age 6 months to 30 months. The association between residential density and parent-child speech was examined. Parents in crowded homes speak in less complex, sophisticated ways with their children compared with parents in uncrowded homes, and this association is mediated by parental responsiveness. Parents in more crowded homes are less verbally responsive to their children. This in turn accounts for their simpler, less sophisticated speech to their children. This mediational pathway is evident with statistical controls for socioeconomic status. This model may help explain prior findings showing a link between residential crowding and delayed cognitive development.     

Predictors of Family Functioning Among Clergy and Spouses: Influences of Social Context and Perceptions of Work-Related Stressors

We wished to identify predictors of family functioning from models including perceptions of stresses associated with mobility, financial compensation, intrusiveness to family boundaries, expectations on time demands, and the lack of social support. Data were collected from 136 randomly selected couples from six denominations in which husbands were clergy. Participants completed a survey that included the Clergy Family Life Inventory which assessed perceptions of five work-related stressors and the Self Report Measure of Family Functioning scale which measured 12 dimensions of family functioning. Separate regression models were tested for husbands and wives and these analyses indicated that no single stressor seemed influential for all 12 dimensions of family functioning. However, for both husbands and wives, family boundary intrusiveness, lack of social support, and mobility stresses influenced their competence in numerous areas of family functioning. In addition, husbands and wives experienced similar effects of stress among several dimensions of family functioning (e.g. enmeshment, family organization, democratic family atmosphere expressiveness).     

A matched-subject comparison of underachievers with normals on intellectual,behavioral, and emotional variables

Children labeled as under achievers are compared to a matched group functioning normally within the classroom. Factor analyses of the data from several tests reveal that the normal children not only have achieved higher academic performance but also have better learning aptitude. The inference may be made that many underachievers actually have a low general aptitude when carefully measured.This study was supported from funds from the Holden Foundation at the Children's Hospital of Michigan.
