    Abstract: Commercial off-the-shelf (COTS) products allow researchers to conduct studies using readily accessible systems in order to save time, effort, and/or money that would otherwise be spent designing a custom product. In this article, we discuss the potential of a low-cost and commercially available video game, FTL: Faster Than Light, to be used as a testbed for research into complex or high-workload situations. In this preliminary review, we prototype a performance assessment tool for FTL, which we call FTL Score, and evaluate its ability to distinguish performances between a pilot sample of three participants. The results of this exploratory study showed that our measurement methods were able to distinguish between the performance of two novices and an expert. This suggests that a larger follow-up study is warranted, and lends some support to the hypothesis that FTL can be used as an easy-to-deploy and low-cost testbed for research into high-workload performance.

    Confusion and Direction in Diagnostic Doppler Sonography
    SAGE Publications ; 2009
    In:  Journal of Diagnostic Medical Sonography Vol. 25, No. 3 ( 2009-05), p. 173-177

    In: Journal of Diagnostic Medical Sonography, SAGE Publications, Vol. 25, No. 3 ( 2009-05), p. 173-177
    Abstract: Spectral and color sonographic Doppler information has become critical to medical imaging and diagnosis. However, there are no standards for the display of the Doppler frequency-shifted sonographic directional information. The display of the spectral and Doppler directional information is arbitrary and under operator control. The authors discuss the current situation of the Doppler directional displays and the problems that may be caused by this confusion.

    Transjugular Intrahepatic Portosystemic Shunt: A Literature Review
    SAGE Publications ; 2018

    In: Journal of Diagnostic Medical Sonography, SAGE Publications, Vol. 34, No. 2 ( 2018-03), p. 114-122
    Abstract: Transjugular intrahepatic portosystemic shunt, or TIPS, is a procedure used to decompress the portal system resulting from portal hypertension. The technique was inadvertently discovered during a transjugular cholangiography procedure around 1969. Technological advances in the 1980s and 1990s have resulted in more positive outcomes for the TIPS procedure since its inception. There are several indications for performing the procedure, including refractory ascites, variceal bleeding, and portal hypertension. Liver disease can lead to portal hypertension, and few treatments are available; however, with TIPS, many patients obtain favorable results. The goal of placing an intrahepatic portosystemic shunt is to bypass the vascular resistance in the cirrhotic liver by creating a channel between the portal and hepatic veins, thereby reducing portal venous pressure and portal hypertension. Normal and diseased liver function is explained as well as the TIPS procedure process, materials, complications, and long-term outcomes.

    Abstract: The occurrence of an ectopic pregnancy that implants within the peritoneal cavity is a rare, life-threatening event. Poor maternal and fetal outcome, especially in pregnancies within the range considered to be viable, is the norm, with most abdominal ectopic pregnancies being terminated early in gestation. We present a case study in which the abdominal pregnancy was detected in the second trimester by sonography and confirmed by magnetic resonance imaging, both of which are considered essential diagnostic tools to provide optimal outcome for maternal and fetal well-being.

    Abstract: Wilson disease, also known as hepatolenticular degeneration, is a disorder in the liver that results in the improper metabolism of copper, which leads to accumulation of excessive amounts of this vital trace element in the liver, brain, eyes, and other organs. Although copper is essential for normal physiologic function, it can become toxic and life-threatening when too much is present within critical organs, especially the liver and the brain. There is no cure for Wilson disease, and patients affected with this disorder face a lifetime of treatment. Fortunately, the disease is very treatable if diagnosed before significant damage to the liver or brain occurs. This article presents a case study on Wilson disease and the role of sonography in helping diagnose and monitor patients with this condition.

    In: Assessment, SAGE Publications, Vol. 11, No. 4 ( 2004-12), p. 303-315
    Abstract: The purpose of this study was to investigate convergent and discriminant validity of the five-factor model of adolescent personality in a school setting using three different raters (methods): self-ratings, peer ratings, and teacher ratings. The authors investigated validity through a multitrait-multimethod matrix and a confirmatory factor analysis correlated trait, uncorrelated method model. With the exception of Emotional Stability, each analysis demonstrated similar patterns and together provided support for the convergent and discriminant validity of the five-factor model structure of adolescent personality. However, among the three raters, self-ratings of personality provided a comparatively weaker method for assessing adolescent personality. The influences of agreement between self and other raters are discussed in relation to contrast, perceiver, and target effects; expert observer effects; the degree of acquaintanceship; and the effect of the social context.

    In: Human Factors: The Journal of the Human Factors and Ergonomics Society, SAGE Publications, Vol. 63, No. 4 ( 2021-06), p. 684-695
    Abstract: The combat identification (CID) abilities of same-gender and mixed-gender dyads were experimentally assessed, along with measures of spatial skills and team communication. Background CID is a high-stakes decision-making task involving discrimination between friendly and enemy forces. Literature on CID is primarily focused on the individual, but the extensive use of teams in the military means that more team-based research is needed in this area. Method After a set of training sessions, 39 dyads were tasked with identifying 10 armored vehicles in a series of pictures and videos. Team communication was recorded, transcribed, and coded for instances of disagreements. Results Analyses indicated that males scored higher on a spatial visualization measure than did females. M-M teams performed significantly better than M-F teams on the CID task, but when spatial ability and team disagreements were added as predictors, the effect of team gender composition became nonsignificant. Spatial ability and team disagreement were significant predictors of team CID performance. Conclusion Results suggest that spatial skills and team disagreement behaviors are more important for team CID performance than a team’s gender composition. To our knowledge, this is the first lab study of team CID. Application This research highlights the importance of understanding both individual differences (e.g., spatial skills) and team processes (e.g., communication) within CID training environments in the military context.

    Abstract: Congenital diaphragmatic hernia (CDH) is an opening in the diaphragm in which the abdominal viscera protrudes into the chest as the result of an embryologic defect. CDH can be an isolated anomaly or occur simultaneously with a chromosomal abnormality or genetic syndrome. Prognosis for fetuses with CDH is widely variable and depends on numerous factors including premature birth, the presence of a chromosomal abnormality or genetic disorder, location of the herniation, lung volume, and cardiac involvement. This study presents details of a case of right-sided CDH with an intrathoracic kidney detected sonographically. Fetal echocardiography and magnetic resonance imaging (MRI) were used to further characterize the herniation. Both sonography and MRI aided in accurate diagnosis and postnatal treatment planning.

    Continuing Medical Education for Sonographers : A Brief History and an Update

    In: Journal of Diagnostic Medical Sonography, SAGE Publications, Vol. 28, No. 5 ( 2012-09), p. 260-262
    Abstract: The requirement for continuing medical education in health care originated in the early 1900s when several investigators in the United States determined that the training physicians were receiving was woefully inadequate. The Flexner Report, which was based on an extensive analysis of how the early medical schools were educating physicians, proposed several radical changes in physician instruction, including a recommendation for postgraduate training. Now known as continuing medical education (CME), this obligation is practically universal in the medical and allied health fields including sonography. Although there are many options for the diagnostic medical sonographer to earn CME credits, the Society of Diagnostic Medical Sonography (SDMS) instituted a unique program for sonographers to earn credits by providing clinical instruction to sonography students. By using electronic data collection and management systems, it is now easy for sonography program directors to submit their clinical instructors for CME credits through the SDMS.
