Detecting Patterns Of Fraudulent Behavior In Forensic Accounting, Boris Kovalerchuk, Evgenii Vityaev
Detecting Patterns Of Fraudulent Behavior In Forensic Accounting, Boris Kovalerchuk, Evgenii Vityaev
All Faculty Scholarship for the College of the Sciences
Often evidence from a single case does not reveal any suspicious patterns to aid investigations in forensic accounting and other forensic fields. In contrast, correlation of sets of evidence from several cases with suitable background knowledge may reveal suspicious patterns. Link Discovery (LD) has recently emerged as a promising new area for such tasks. Currently LD mostly relies on deterministic graphical techniques. Other relevant techniques are Bayesian probabilistic and causal networks. These techniques need further development to handle rare events. This paper combines first-order logic (FOL) and probabilistic semantic inference (PSI) to address this challenge. Previous research has shown this …

This paper introduces an extended hierarchical task analysis (HTA) methodology devised to evaluate and compare user interfaces on volumetric infusion pumps. The pumps were studied along the dimensions of overall usability and propensity for generating human error. With HTA as our framework, we analyzed six pumps on a variety of common tasks using Norman’s Action theory. The introduced method of evaluation divides the problem space between the external world of the device interface and the user’s internal cognitive world, allowing for predictions of potential user errors at the human-device level. In this paper, one detailed analysis is provided as an …
Rigorously Assessing Whether The Data Backs The Back School, David T. Vinh, Craig W. Johnson, Cynthia L. Phelps
Rigorously Assessing Whether The Data Backs The Back School, David T. Vinh, Craig W. Johnson, Cynthia L. Phelps
Faculty, Staff and Student Publications
A rigorous between-subjects methodology employing independent random samples and having broad clinical applicability was designed and implemented to evaluate the effectiveness of back safety and patient transfer training interventions for both hospital nurses and nursing assistants. Effects upon self-efficacy, cognitive, and affective measures are assessed for each of three back safety procedures. The design solves the problem of obtaining randomly assigned independent controls where all experimental subjects must participate in the training interventions.
Randomized Comparisons Among Health Informatics Students Identify Hypertutorial Features As Improving Web-Based Instruction, Craig W. Johnson, Yan Xing, Lan Yang
Randomized Comparisons Among Health Informatics Students Identify Hypertutorial Features As Improving Web-Based Instruction, Craig W. Johnson, Yan Xing, Lan Yang
Faculty, Staff and Student Publications
Hypertutorials optimize five features - presentation, learner control, practice, feedback, and elaborative learning resources. Previous research showed graduate students significantly and overwhelmingly preferred Web-based hypertutorials to conventional "Book-on-the-Web" statistics or research design lessons. The current report shows that the source of hypertutorials' superiority in student evaluations of instruction lies in their hypertutorial features. Randomized comparisons between the two methodologies were conducted in two successive iterations of a graduate level health informatics research design and evaluation course. The two versions contained the same text and graphics, but differed in the presence or absence of hypertutorial features: Elaborative learning resources, practice, feedback, …

It is becoming clear that if we are to impact the rate of medical errors it will have to be done at the practicing physician level. The purpose of this project was to survey the attitude of physicians in Alabama concerning their perception of medical error, and to obtain their thoughts and desires for medical education in the area of medical errors. The information will be used in the development of a physician education program.
Encouraging Adolescents Toward Mental Health Careers Via Website Biographies, Irmi U. Willcockson, Prabhu R. Shankar, Cynthia L. Phelps, Craig W. Johnson
Encouraging Adolescents Toward Mental Health Careers Via Website Biographies, Irmi U. Willcockson, Prabhu R. Shankar, Cynthia L. Phelps, Craig W. Johnson
Faculty, Staff and Student Publications
This project designed, developed, implemented and is currently evaluating the effectiveness of an interactive, multi-media website designed to encourage adolescents to consider careers in mental health. This Web-based learning environment features biographies of mental health scientists. Evaluation is conducted in a systematic, structured way using cognitive achievement, usability (ease of use), and affective scales (e.g., fun to use) as outcome measures
