Physics Faculty Publications

We report on the first measurement of the beam-spin asymmetry in the exclusive process of coherent deeply virtual Compton scattering off a nucleus. The experiment uses the 6 GeV electron beam from the Continuous Electron Beam Accelerator Facility (CEBAF) accelerator at Jefferson Lab incident on a pressurized ⁴He gaseous target placed in front of the CEBAF Large Acceptance Spectrometer (CLAS). The scattered electron is detected by CLAS and the photon by a dedicated electromagnetic calorimeter at forward angles. To ensure the exclusivity of the process, a specially designed radial time projection chamber is used to detect the recoiling ^{4 …}

Perspective: The Physics, Diagnostics, And Applications Of Atmospheric Pressure Low Temperature Plasma Sources Used In Plasma Medicine, M. Laroussi

Electrical & Computer Engineering Faculty Publications

Low temperature plasmas have been used in various plasma processing applications for several decades. But it is only in the last thirty years or so that sources generating such plasmas at atmospheric pressure in reliable and stable ways have become more prevalent. First, in the late 1980s, the dielectric barrier discharge was used to generate relatively large volume diffuse plasmas at atmospheric pressure. Then, in the early 2000s, plasma jets that can launch cold plasma plumes in ambient air were developed. Extensive experimental and modeling work was carried out on both methods and much of the physics governing such sources …

Initial Construct Validity Evidence Of A Virtual Human Application For Competency Assessment In Breaking Bad News To A Cancer Patient, Timothy C. Guettermann, Frederick W. Kron, Toby C. Campbell, Mark W. Scerbo, Amy B. Zelenski, James F. Cleary, Michael D. Fetters

Psychology Faculty Publications

Background: Despite interest in using virtual humans (VHs) for assessing health care communication, evidence of validity is limited. We evaluated the validity of a VH application, MPathic-VR, for assessing performance-based competence in breaking bad news (BBN) to a VH patient.

Methods: We used a two-group quasi-experimental design, with residents participating in a 3-hour seminar on BBN. Group A (n=15) completed the VH simulation before and after the seminar, and Group B (n=12) completed the VH simulation only after the BBN seminar to avoid the possibility that testing alone affected performance. Pre-and postseminar differences for Group A were analyzed with a …

Management Strategy Evaluation For The Atlantic Surfclam (Spisula Solidissima) Using A Spatially Explicit, Vessel-Based Fisheries Model, Kelsey M. Kuykendall, Eric N. Powell, John M. Klink, Paula T. Moreno, Robert T. Leaf

CCPO Publications

The commercially valuable Atlantic surfclam (Spisula solidissima) is harvested along the northeastern continental shelf of the United States. Its range has contracted and shifted north, driven by warmer bottom water temperatures. Declining landings per unit of effort (LPUE) in the Mid-Atlantic Bight (MAB) is one result. Declining stock abundance and LPUE suggest that overfishing may be occurring off New Jersey. A management strategy evaluation (MSE) for the Atlantic surfclam is implemented to evaluate rotating closures to enhance Atlantic surfclam productivity and increase fishery viability in the MAB. Active agents of the MSE model are individual fishing vessels with …

Dental Hygienists' Perspectives On Four Periodontal Instrument Handle Designs, Susan L. Tolle, Jessica Suedbeck, Gayle M. Mccombs, Martha L. Walker

Dental Hygiene Faculty Publications

Problem: Developing new instrument designs to address the ergonomics of instrumentation and to decrease repetitive strain injuries in the dental hygienist is an ongoing area of development. Changing the weight and diameter of instrument handles has been suggested to reduce risk for trauma in the practitioner but minimal research has been conducted to determine design preferences of practicing dental hygienists. Objective: The purpose of this study was to assess dental hygienists opinions on the weight, diameter, balance and maneuverability of four different instrument handles. Methodology: After IRB approval, a convenience sample of 27 practicing dental hygienists from Virginia participated in …

Error Aggregation In The Reengineering Process From 3d Scanning To Printing, Jennifer G. Michaeli, Matthew C. Degroff, Roman C. Roxas

Engineering Technology Faculty Publications

This work aims to study the aggregation of dimensional errors in the reengineering processes using 3D scanning and printing without initial design drawings. A 57-tooth spur gear is used as an example to facilitate the discussion. Two approaches are investigated. The first one builds the gear model based upon measurement taken from a caliper, and the second approach uses a 3D scanner to collect geometry data. Dimensional errors in each stage of these two approaches are investigated. Particular attention is paid to the geometry data flow in the reengineering process from data acquisition and editing to model construction. Recommendations are …

Human Services Students Preferences For Master's Level Training, Tammi F. Dice, Mark C. Rehfuss

Counseling & Human Services Faculty Publications

Human Services students close to graduation are seeking employment in the field, but many are also considering their future career paths and the training needed to reach their long-term career goals. Knowing if bachelor's level students desire graduate degrees, which focus they prefer, and how they would like to pursue the degrees may contribute to the decision-making of educators, employers, and students. This exploratory study, therefore, examined human services students' preferences for master's level training. Students' responses reflected preferences for several types of master's programs, direct acceptance, and online delivery. These themes and their implications for educators, employers, and students …

Telehealth And Ehealth In Nurse Practitioner Training: Current Perspectives, Carolyn M. Rutledge, Karen Kott, Rebecca Poston, Christianne Fowler, Tina S. Haney

Nursing Faculty Publications

Telehealth is becoming a vital process for providing access to cost-effective quality care to patients at a distance. As such, it is important for nurse practitioners, often the primary providers for rural and disadvantaged populations, to develop the knowledge, skills, and attitudes needed to utilize telehealth technologies in practice. In reviewing the literature, very little information was found on programs that addressed nurse practitioner training in telehealth. This article provides an overview of both the topics and the techniques that have been utilized for training nurse practitioners and nurse practitioner students in the delivery of care utilizing telehealth. Specifically, this …
