Objective: The aim of this study was to determine if first-year physical exam and interview Objective Structured Clinical Examination scores differ for medical students entering person or technique-oriented specialties. Methods: Objective Structured Clinical Examination physical exam and interview scores from 2004 to 2007 for first-year medical students (n=280) at one United States medical school were compared using t-tests based on specialty choice from this cohort of students. Results: T-test results (p<0.05) showed a significant difference in the mean physical exam (mean=92.85, sd=3.94) versus interview (mean=90.77, sd=6.76) scores for students entering person-oriented specialties (n=157, p<0.001). There was also a significant difference (p<0.05) in the mean physical exam (mean=93.46, sd=3.92) versus interview (mean=91.40, sd=5.75) scores for students entering technique-oriented specialties (n=123, p<0.001). Results indicate that physical exam scores are significantly higher than interview scores for students regardless of whether they enter person or technique-oriented specialties, except for psychiatry where interview scores were significantly higher than physical exam scores. Conclusion: Subsequent studies are needed to better understand the relationship of Objective Structured Clinical Examination performance and specialty choice by medical students.

Video games played on computers, game consoles, tablets and smart phones have become a very popular medium in our society. A growing body of scholarship suggests that video games can support substantial learning (for reviews see Gee, 2007; Honey & Hilton, 2011; Squire, 2011). Research has documented ways in which games engage students deeply in thinking, learning, and collaboration (Gee, 2005). Evidence suggests that games can support development of critical thinking (Squire, 2006), creativity (Annetta, Cheng, & Holmes, 2010), and mastery and application of target concepts (Squire, 2011).

It was believed that the reason for decline in Asian vulture population is the drug, Diclofenac sodium (DFS), used in livestock. Even after declaring the DFS use banned by the government, apparent decrease in the population of vultures was reported. Alternate hypothesis was suggested that food limitation may be a cause of Asian vulture crisis in Pakistan. Very recent shifts in livestock utilization observed in Pakistan may present a significant barrier to vulture recovery. Increased livestock utilization is translated to fewer carcasses. Since 2005, no livestock carcasses were found in 1650 km transect in the habitat of vultures. Carcasses recorded …

Oxidative stress-induced endothelial dysfunction plays a key role in ischemia/reperfusion injury. Recent evidence indicates that endothelial progenitor cell-derived microvesicles (EPC-MVs) can promote angiogenesis of endothelial cells (ECs). Here, we investigated the potential effects of EPC-MVs on hypoxia/reoxygenation (H/R) injury in human brain microvascular ECs (hb-ECs). MVs were prepared from EPCs cultured in a serum deprivation (SD) medium (starving stress, sEPC-MVs) or SD medium containing tumor necrosis factor-α (TNFα) (apoptotic stress, aEPC-MVs). H/R injury model of hb-ECs was produced by 6 hr hypoxia (1% O2) and 24 hr reoxygenation. The H/R hb-ECs were co-cultured with EPC-MVs. Results showed that …

Effects Of Nextgen Concepts For Separation Assurance And Interval Management On Atco Situation Awareness, Thomas Z. Strybel, Kim-Phuong L. Vu, Dan Chiappe, Corey A. Morgan, Vernol Battiste
International Symposium on Aviation Psychology - 2013
We examined the effects of responsibility for interval management and separation assurance on ATCo situation awareness, workload and performance. Four conditions were tested by crossing two strategies for interval management (ATCo responsible or flight deck responsible) and two strategies for separation assurance (ATCo primary or automation primary). Situation awareness and workload were assessed with an online probe technique. Workload was lowest when both functions were automated, but situation awareness for conflicts depended on the sector. Both workload and situation awareness were related to the number of ATCo-managed LOS.

Transferring Human Factors Knowledge From Aviation To Development Of A Warning System For Landslide, Ioana Koglbauer, Guenter Hohenberger, Christian Steger
International Symposium on Aviation Psychology - 2013
There is a successful history of transferring knowledge from aviation to other domains such as medicine (Thomas & Helmreich, 2002). In this study the ICAO multistage alerting service (2008) served as model for the specification of an early warning system for landslide. The early warning system is designed to monitor mass-movement data provided by GPS sensors, and to generate warnings and alarms to the National Alarm- and Warning Center of Styria, Austria. For the human factors specification of the new system a qualitative analysis was performed. Results are discussed with regard to applicability of human factors guidelines from aviation to …
Tracking And Visuospatial Working Memory, Robin Langerak, Chris M. Herdman, James Howell Ba
Tracking And Visuospatial Working Memory, Robin Langerak, Chris M. Herdman, James Howell Ba
International Symposium on Aviation Psychology - 2013
The present research examines the role of visuospatial working memory in supporting pursuit tracking. Participants completed a pursuit motor tracking task while simultaneously completing secondary tasks designed to separately place demands on either storage or processing in visuospatial working memory. The results show that simple pursuit tracking utilizes visuospatial processing in working memory without a strong requirement for visuospatial storage. These findings have implications for understanding time-sharing of tasks in the cockpit.

International Symposium on Aviation Psychology - 2013
Human factors specialists work as part of multidisciplinary teams supporting acquisition programs. Depending upon the acquisition model and culture of an organization, the exact points of involvement of human factors specialists may vary, as too will the metrics of success for each project. Acceptable/optimal level of operational performance is the goal of any Air Traffic Control (ATC) system. Human performance is a key component of operational performance. Measuring human performance can be an area of academic debate often yielding vague answers or need for more research. This is of little use or interest to project and senior managers who make …

Intrinsic optical signals (IOS) were used to evaluate volume regulation mechanisms during Schaffer collateral stimulation-induced volume changes in hippocampal slices. The effects of stimulation frequency, synaptic function, ionotropic glutamate receptor (iGluR) activation, glutamate uptake, and volume regulatory anion channels (VRAC) were examined with IOS. Data were analyzed using ANOVA with Dunnett's post hoc test (p<0.05 indicated significance). IOS changes were stimulation frequency dependent between 1 Hz and 10 Hz with full recovery of IOS within 5 min. Synaptic blockage reduced the rate of swelling by 81% compared to the control and the IOS did not fully recover. Recovery rate was reduced with iGluR inhibition. Inhibition of glutamate uptake reduced the rate of swelling by 70% compared to vehicle controls. During stimulation, action potentials, iGluR activation, and glutamate uptake contribute to swelling. Regulatory volume mechanisms during stimulation were glutamate-mediated via iGluRs and VRAC independent.
C-Bouton Coverage Of Alpha-Motoneurons Following Peripheral Nerve Injury, Esra Salah Shermadou
C-Bouton Coverage Of Alpha-Motoneurons Following Peripheral Nerve Injury, Esra Salah Shermadou
Browse all Theses and Dissertations
Peripheral nerve injuries (PNI) cause alternations in central synapses leading to loss of function. The C-bouton synapses onto a-motoneurons in the ventral horn, and has a role in regulating motor output. Following tibial nerve ligation, the somatic C-bouton coverage is depleted (Alvarez et al., 2011), however, it is unknown what happens following crush type injuries. PNI causes neuroglia activation and proliferation that contribute to synaptic alterations, a response that has not been well-characterized in the ventral horn, where motoneurons are located. Therefore, I hypothesize that glia activation following peripheral nerve injury correlates to the degree of depletion of synaptic coverage …
