Creating Safety In The Diagnostic Testing Processes Of Family Medical Practices, Timothy Ryan Mcewen
Creating Safety In The Diagnostic Testing Processes Of Family Medical Practices, Timothy Ryan Mcewen
Browse all Theses and Dissertations
Four mid-Western family practices were studied using three methods (observations, interviews, and an audit of patient records) in effort to discover the dynamics and constraints of their diagnostic testing processes. We have found further evidence that errors do occur at many of the steps in the processes, but that the patterns of those errors are not independent of each other and are a function of systemic factors unique to each practice. Furthermore, while many employees or steps in the process may be considered a source of error, they were also shown to be major sources of quality and safety in …

Recent developments in organizational attitude research have focused on the concept of engagement. Despite the growing literature on engagement there is little agreement on the conceptualization of engagement. The current study sought to conceptualize and measure work engagement using Item Response Theory. The Wright Work Engagement Scale was created using two samples, a student sample for exploratory analyses and a working sample for item analyses. Results indicate engagement is a unidimensional construct. The 12 item Work Engagement Scale was created and demonstrated sufficient convergent and discriminant validity.
Effects Of Big 5 Personality Traits On Outcomes For Error Encouragement And Error Avoidant Training, Keith Alan Leas
Effects Of Big 5 Personality Traits On Outcomes For Error Encouragement And Error Avoidant Training, Keith Alan Leas
Browse all Theses and Dissertations
The purpose of this study was to examine the effects of the type of training used (error avoidant or error encouragement) as a moderator of the relationship between personality variables and training outcomes. Specifically, we hypothesized that we would observe stronger effects of personality (i.e., conscientiousness and openness) on performance (Hypothesis 1) and affectivity (Hypothesis 2) for individuals in the error encouragement condition than for individuals in the error avoidant condition. Further, we hypothesized that we would see stronger moderating effects for training type for the above personality variables than for extraversion or agreeableness (Hypothesis 3). We recruited 257 participants …

Research has found that the use of social desirability scales to measure faking is problematic. The current study employed a job desirability scale consisting of job-specific bogus biographical items as an alternative faking measure in an applied setting. Using a 2 (applicants versus incumbents) x 2 (sales versus managers) design, participants (N = 958), participants completed a set of personality, social desirability, and job desirability measures. Results indicated that applicants outscored incumbents on personality measures. However, the effect size for conscientiousness was larger for the manager job whereas the effect size for extraversion was larger for the sales job, indicating …
Attentional Limitations And The Visual Pathways, Satomi Maeda
Attentional Limitations And The Visual Pathways, Satomi Maeda
Browse all Theses and Dissertations
The present study tested the hypothesis that three visual pathways (i.e. parvocellular, magnocellular, and koniocellular pathways) may influence the degree of dual-task interference using dual-task methodology. The magnocellular pathway consists of feature-coding mechanisms that are sensitive to transients and motion, and is thought to process information about the locations and movements of objects. The parvocellular pathway consists of feature-coding mechanisms that are sensitive to red-green and brightness information, while the koniocellular pathway consists of feature-coding mechanisms that are sensitive to blue-yellow chromatic information. Both the parvocellular and the koniocellular pathway are thought to process information useful for identifying objects. The …
Role Of Enriched Representations In Collaborative Planning Processes, Elizabeth A. Lerner
Role Of Enriched Representations In Collaborative Planning Processes, Elizabeth A. Lerner

The current study addressed the function of representing constraints in a display that is used for the process of planning on a team level. The experimental task was a modification of a game entitled 10 Days in Africa in which the players must complete a journey through the continent of Africa. Dyads participated in the game by constructing their own planning representations, as well as collaborating with the other player. We augmented the standard Gantt chart representation of timeline events with representations for the constraints holding between adjacent events. To examine the function of constraint representation in planning, we examined …
Bounded Rationality In The Emergency Department, Markus Alexander Feufel
Bounded Rationality In The Emergency Department, Markus Alexander Feufel
Browse all Theses and Dissertations
This research aimed at understanding bounded rationality - that is, how simple heuristics result in satisfactory outcomes - in a naturalistic setting where agents have to meet environmental demands with limited resources. To do so, two methodological approaches were taken, an observational and an experimental study of U.S. emergency physicians who have to provide a satisfactory level of care while simultaneously coping with uncertainty, time and resources constraints. There are three major findings. First, based on observations of 12 resident and 6 attending physicians at two Midwestern emergency departments (ED), ED physicians use at least two general heuristics. One heuristic …
Role Of Assigned Team Goals In The Relationship Between Individual Difference Factors And Self-Set Goals In A Pre-Team Context, Anupama Narayan
Role Of Assigned Team Goals In The Relationship Between Individual Difference Factors And Self-Set Goals In A Pre-Team Context, Anupama Narayan
Browse all Theses and Dissertations
The purpose of the present study was to examine the effects of individual difference factors, i.e., core self evaluations, cognitive ability, and task specific self-efficacy, on self-set goals and whether those effects were moderated by an assigned team goal in a pre-team context. It was hypothesized that the relationship between individual difference factors and self-set goals for potential team members would be differentially affected by the difficulty of the assigned team goal. I assessed these relationships for individual performance and individual satisfaction. In addition, I examined whether gender, task type, and team composition interacted in their effects on self-set goals. …

Following Dominguez (1997), we tested for differences among 10 resident surgeons' eye-scanning patterns during a laparoscopic cholecystectomy video. We measured time, number of fixations on anatomy and instruments, discomfort level ratings, notation of cystic artery, and conversion to open-incision. We expected our 10 residents would fall into two scanning strategies, proactive or reactive. Proactive strategists were defined as more skilled (year in residency, cases performed), anticipatory of danger (time and fixations on anatomy), observant of the pulsing cystic artery, and converting from laparoscopy to open when highly uncomfortable. Reactive strategists were expected to spend more time on instruments, have low …

Visual Contributions To Spatial Perception During A Remote Navigation Task, Candace Lee Eshelman-Haynes
Browse all Theses and Dissertations
The purpose of this study was to explore the implications of perception and action coupling for the design of control and display interfaces in remotely piloted vehicles. Three experiments were conducted: spatial arrangement, path perception, and remote navigation. The results showed that panning independent of forward motion gives observers a greater sense of depth in a scene and aides in efficient navigation while rotation during forward motion results in ambiguities during passive observation. This research has implications for the design of control and visualization interfaces for remote navigation.

This study investigated an alternative training approach that would improve transfer performance scores above traditional training approaches. Specifically, error-management training was proposed to help trainees learn complex tasks, as opposed to error-avoidant training approaches, which sought to give trainees step-by-step protocols for learning that would minimize the occurrence of errors during training. This study was designed to examine the effects of training type on transfer performance and transfer errors, as well as the effects of meta-cognition, emotion control and cognitive appraisals as mediators of the training type-performance relationship. A third issue of this study investigated the personality-training type interactions from …
The Effect Of Story Structure On Memory For Technical Instructions, Pamela R. Dowling
The Effect Of Story Structure On Memory For Technical Instructions, Pamela R. Dowling
Browse all Theses and Dissertations
Stories represent an important key to how people remember information. Psychology has characterized stories in terms of grammars, which are lists of components typically found in stories (e.g., setting, protagonist, causal sequence etc.). This has a tendency to limit the definition of a story to grammars and negate the importance of ideas such as content. The present research hopes to expand the definition of a story by introducing another set of literature, namely speech act theory. According to speech act theory, conversations include more information than regular text regarding expectations among the conversational participants and common patterns of conversational exchange. …

Type I Error Rates And Power Estimates For Several Item Response Theory Fit Indices, Bradley R. Schlessman
Browse all Theses and Dissertations
Despite frequent use of the adjusted chi-square to degrees of freedom ratio (χ2/df) test for Item Response Theory fit (Drasgow, Levine, Tsien, Williams. and Mead, 1995), there remains a lack of empirical testing of the statistic's Type I error rates and power. The present study compared the adjusted χ2/df test to two other commonly used IRT fit statistics. The other fit indices examined were S-χ2 (Orlando and Thissen, 2000) and χ2* (Stone's, 2000). This study also addressed misfit based on the possibility that the item responses analyzed were created based on a different response process than that assumed by the …
