The Health Professional Ethics Rubric: Practical Assessment in Ethics Education for Health Professional Schools

A barrier to the development and refinement of ethics education in and across health professional schools is that there is not an agreed upon instrument or method for assessment in ethics education. The most widely used ethics education assessment instrument is the Defining Issues Test (DIT) I & II. This instrument is not specific to the health professions. But it has been modified for use in, and influenced the development of other instruments in, the health professions. The DIT contains certain philosophical assumptions (??Kohlbergian?? or ??neo-Kohlbergian??) that have been criticized in recent years. It is also expensive for large institutions to use. The purpose of this article is to offer a rubric??which the authors have named the Health Professional Ethics Rubric??for the assessment of several learning outcomes related to ethics education in health science centers. This rubric is not open to the same philosophical critiques as the DIT and other such instruments. This rubric is also practical to use. This article includes the rubric being advocated, which was developed by faculty and administrators at a large academic health science center as a part of a campus-wide ethics education initiative. The process of developing the rubric is described, as well as certain limitations and plans for revision.     

A factor-adjusted multiple testing procedure for ERP data analysis

Event-related potentials (ERPs) are now widely collected in psychological research to determine the time courses of mental events. When event-related potentials from treatment conditions are compared, often there is no a priori information on when or how long the differences should occur. Testing simultaneously for differences over the entire set of time points creates a serious multiple comparison problem in which the probability of false positive errors must be controlled, while maintaining reasonable power for correct detection. In this work, we extend the factor-adjusted multiple testing procedure developed by Friguet, Kloareg, and Causeur (Journal of the American Statistical Association, 104, 1406-1415, 2009) to manage the multiplicity problem in ERP data analysis and compare its performance with that of the Benjamini and Hochberg (Journal of the Royal Statistical Society B, 57, 289-300, 1995) false discovery rate procedure, using simulations. The proposed procedure outperformed the latter in detecting more truly significant time points, in addition to reducing the variability of the false discovery rate, suggesting that corrections for mass multiple testings of ERPs can be much improved by modeling the strong local temporal dependencies.     

The Connection Between Happiness and Service Businesses: A Preliminary Study

Happiness may be one of the most important goals that many people pursue in the world. This study adopts a qualitative approach to investigate the determinants of happiness for Taiwanese/Chinese people. Further, we investigate related service opportunities for happiness via a field survey of 808 respondents. This study identifies four happiness segments for people in Taiwan/China: Influential & Outgoing, Adequately Settled, Pleasure Seeking, and Young & Restless. These four happiness segments differ markedly in terms of characteristics and potential service opportunities. The findings of this study have implications for researchers who are seeking to understand happiness in an Asian country.     

Functional heterogeneity of inferior frontal gyrus is shaped by linguistic experience

A crosslinguistic, positron emission tomography (PET) study was conducted to determine the influence of linguistic experience on the perception of segmental (consonants and vowels) and suprasegmental (tones) information. Chinese and English subjects (10 per group) were presented binaurally with lists consisting of five Chinese monosyllabic morphemes (speech) or low-pass-filtered versions of the same stimuli (nonspeech). The first and last items were targeted for comparison; the time interval between target tones was filled with irrelevant distractor tones. A speeded-response, selective attention paradigm required subjects to make discrimination judgments of the target items while ignoring intervening distractor tones. PET scans were acquired for five tasks presented twice: one passive listening to pitch (nonspeech) and four active (speech = consonant, vowel, and tone; nonspeech = pitch). Significant regional changes in blood flow were identified from comparisons of group-averaged images of active tasks relative to passive listening. Chinese subjects show increased activity in left premotor cortex, pars opercularis, and pars triangularis across the four tasks. English subjects, on the other hand, show increased activity in left inferior frontal gyrus regions only in the vowel task and in right inferior frontal gyrus regions in the pitch task. Findings suggest that functional circuits engaged in speech perception depend on linguistic experience. All linguistic information signaled by prosodic cues engages left-hemisphere mechanisms. Storage and executive processes of working memory that are implicated in phonological processing are mediated in discrete regions of the left frontal lobe.     

Child-rearing antecedents of intergenerational relations in young adulthood: a prospective study.

Data gathered from mothers on parenting and family climate when almost 1,000 children in the Dunedin, New Zealand, longitudinal study were 3, 5, 7, 9, 13, and 15 years of age were used to predict intergenerational relations between young adult children (age 26) and their middle-aged parents. Analyses focused on distinct developmental epochs revealed greater prediction from the middle-childhood and early-adolescent periods than from the early-childhood years: most indicated that more supportive family environments and child-rearing experiences in the family of origin forecasted more positive and less negative parent-child relationships (in terms of contact, closeness, conflict, reciprocal assistance) in young adulthood, though associations were modest in magnitude. Some evidence indicated that (modestly) deleterious effects on intergenerational relations of experiencing relatively unsupportive child-rearing environments in 1 but not 2 (of 3) developmental periods studied could be offset by relatively supportive family environments in the remaining developmental periods.     

Employees' reactions to psychological contract breach: A moderated mediation analysis

This study examined the mediating role of acquiescent silence in the relationship between psychological contract breach and employee job satisfaction, as well as the moderating roles of perceived ethical climate on that relationship and on the mediation effect of acquiescent silence. Survey data were collected from a sample of 273 full-time employees from nine high-tech firms in Taiwan. The results showed that acquiescent silence partially mediated the relationship between psychological contract breach and job satisfaction. Moreover, the results from the moderation analysis showed that perceived ethical climate moderated the influence of psychological contract breach on acquiescent silence and the results from the moderated mediation analysis revealed that this mediation of acquiescent silence was moderated by perceived ethical climate such that at the lower level of perceived ethical climate, the mediation effect of acquiescent silence became stronger. Implications for managerial practices and suggestions for future research were discussed.     

Optimal sequences of trials for balancing practice and repetition effects

This paper describes procedures for generating trial sequences to balance out practice effects and intertrial repetition effects in experiments consisting of repeated trials. In the sequences presented, each stimulus appears an equal number of times, is preceded equally often by itself and by each other stimulus, and is distributed in a “balanced” manner throughout the block of trials. Two criteria for balance are employed. One criterion aims to equalize the average position of each stimulus in the sequence. The second criterion maintains, as much as possible, a uniform interval between appearances of each stimulus in the sequence. For each criterion, optimal or near-optimal sequences are presented for experiments involving from three to nine different stimulus conditions. Suggestions are included for extending (e.g., doubling or tripling) the length of the sequences.     

BOLD activation varies parametrically with corner angle throughout human retinotopic cortex

The Alternating Brightness Star (ABS) is an illusion that provides insight into the relationship between brightness perception and corner angle. Recent psychophysical studies of this illusion have shown that corner salience varies parametrically with corner angle, with sharp angles leading to strong illusory percepts and shallow angles leading to weak percepts. It is hypothesized that the illusory effects arise because of an interaction between surface corners and the shape of visual receptive fields: sharp surface corners may create hotspots of high local contrast due to processing by center-surround and other early receptive fields. If this hypothesis is correct, early visual neurons should respond powerfully to sharp corners and curved portions of surface edges. Indeed, the primary role of early visual neurons may be to localize the discontinuities along the edges of surfaces. If so, all early visual areas should show greater BOLD responses to sharp corners than to shallow corners. On the other hand, if corner processing is exclusively constrained to certain areas of the brain, only those specific areas will show greater responses to sharp vs shallow corners. To address this we explored the BOLD correlates of the ABS illusion in the human visual cortex using fMRI. We found that BOLD signal varies parametrically with corner angle throughout the visual cortex, offering the first neurophysiological correlates of the ABS illusion. This finding provides a neurophysiological basis for the previously reported psychophysical data that showed that corner salience varied parametrically with corner angle. We propose that all early visual areas localize discontinuities along the edges of surfaces, and that specific cortical corner-processing circuits further establish the specific nature of those discontinuities, such as their orientation.
