Proceed To Checkout? The Impact Of Time In Advanced Ticket Purchase Decisions, Brendan Dwyer, Joris Drayer, Stephen L. Shapiro

Human Movement Studies & Special Education Faculty Publications

When purchasing tickets in advance, sports consumers are often faced with uncertainty. Most notably, in today's real-time environment, it can be challenging for consumers to determine how ticket prices and seat availability will change over time. Guided by the generic advanced-booking decision model, the current study investigated the role of time, ticket source (primary or secondary market), and team identification in advanced ticket purchasing by exploring a consumer's perceptions of ticket availability and finding a lower price. The results suggest the perceived likelihood of ticket availability and finding a lower priced ticket increased as the date of the game drew …

Children in food-insecure households are more likely to experience poorer health function and worse academic achievement. To investigate the relation between economic environmental factors and food insecurity among children, we examined the relation between general and specific food prices (fast food, fruits and vegetables, beverages) and risk of low (LFS) and very low food security (VLFS) status among low-income American households with children. Using information for 27,900 child-year observations from the Early Childhood Longitudinal Study-Kindergarten Class of 1998 1999 linked with food prices obtained from the Cost of Living Data of the Council for Community and Economic Research, formerly known …

Nanosecond Pulsed Electric Field (Nspef) Ablation As An Alternative Or Adjunct To Surgery For Treatment Of Cancer, Ru Chen, Xinhua Chen, Stephen J. Beebe

Bioelectrics Publications

Surgery as resection or transplantation remains a fundamental means for cancer treatment and often offers an opportunity for a cure. However, surgery is not always possible because of tumor proximity to blood vessels or ducts or when a patient is not healthy enough to undergo surgery. Application of nanosecond pulsed electric fields (nsPEFs) is a new approach to treat cancer using pulse power technology that was originally designed for military purposes. This novel approach deposits extremely short pulses of high power, low energy electric fields into malignant tissues using electrodes to encompass tumors. Pre-clinical studies show that treatments are effective …

Atomic Force Microscopy Characterization Of Collagen ‘Nanostraws’ In Human Costal Cartilage, Michael W. Stacey, Diganta Dutta, Anthony Asmar, H. Elsayed-Ali, R. Kelly Jr., A. Beskok

Bioelectrics Publications

Costal cartilage, a type of hyaline cartilage that bridges the bony ribs and sternum, is relatively understudied compared to the load bearing cartilages. Deformities of costal cartilage can result in deformation of the chest wall, where the sternum is largely pushed toward or away from the spine, pectus excavatum and pectus carinatum, respectively, with each condition having significant clinical impact. In the absence of extensive literature describing morphological features of costal cartilage, we characterized a sample from the costal margin immunohistologically and through atomic force microscopy. We had previously observed the presence of collagen ‘nanostraws’ running the length of costal …

Impulsivity Like Traits And Risky Driving Behaviors Among College Students, Matthew R. Pearson, Elaine M. Murphy, Ashley N. Doane

Psychology Faculty Publications

The present study examined the predictive effects of five impulsivity-like traits (Premeditation, Perseverance, Sensation Seeking, Negative Urgency, and Positive Urgency) on driving outcomes (driving errors, driving lapses, driving violations, cell phone driving, traffic citations, and traffic collisions). With a convenience sample of 266 college student drivers, we found that each of the impulsivity-like traits was related to multiple risky driving outcomes. Positive Urgency (tendency to act impulsively when experiencing negative affect) was the most robust predictor of risky driving outcomes. Positive Urgency is a relatively newly conceptualized impulsivity-like trait that was not examined in the driving literature previously, suggesting a …

Fine Tuning A Well-Oiled Machine: Influence Of Nk1.1 And Nkg2d On Nkt Cell Development And Function, Sunil K. Joshi, Mark L. Lang

Bioelectrics Publications

Natural killer T cells (NKT) represent a group of CD1d-restricted T-lineage cells that provide a functional interface between innate and adaptive immune responses in infectious disease, cancer, allergy and autoimmunity. There have been remarkable advances in understanding the molecular events that underpin NKT development in the thymus and in the complex array of functions in the periphery. Most functional studies have focused on activation of T cell antigen receptors expressed by NKT cells and their responses to CD1d presentation of glycolipid and related antigens. Receiving less attention has been several molecules that are hallmarks of Natural Killer (NK) cells, but …

Membrane Surface Charges Attracted Protons Are Not Relevant To Proton Motive Force, James Weifu Lee

Chemistry & Biochemistry Faculty Publications

[First Paragraph] Only a half-century ago, British scientist Peter Mitchell proposed the conceptual scheme known as "chemiosmotic theory" that identified the role of proton coupling in the formation of ATP in cells [1,2]. Mitchell's delocalized proton-coupling chemiosmotic theory was initially quite controversial. But it would win for him the Nobel Prize in Chemistry in 1978. However, questions about Mitchell's chemiosmotic hypothesis have never gone away and a number of credible studies indicated the full extent of Mitchell's idea didn't always hold up to experience.

Urban Adventure Racing: Using Grounded Theory To Assess Motives, Eddie Hill, Edwin Gómez, Brandi Brinkley, Marni Goldenberg

Human Movement Studies & Special Education Faculty Publications

Although urban adventure races (ARs) have grown in popularity, little research exists on the reasons for the rising interest. Typically, adventure races are defined as a series of outdoor tasks completed within a given course or timeframe that are meant to challenge individuals, both mentally and physically. ARs borrow much from adventure programming. Aspects of AR programming may include goal-setting, problem-solving activities, and processing, and is often theoretically driven. This study used Grounded Theory as a basis for exploring why participants choose ARs, and if motives vary by gender. Of the 60 questionnaires collected, 40 were suitable for data analysis. …

Disparate Health Implications Stemming From The Propensity Of Elderly And Medically Fragile Populations To Shelter In Place During Severe Storm Events, Joshua G. Behr, Rafael Diaz

VMASC Publications

Chronic conditions, disability limitations (mobility, cognitive, and sensory), and the need for assistance with activities of daily living are characteristics of elderly and medically fragile populations. Theory suggests that households with these vulnerability attributes are more likely to suffer storm-induced adverse and prolonged health consequences and, therefore, ought to evidence an increased propensity to evacuate prior to a severe storm event. Yet despite being more sensitive to storm disruption, the elderly and medically fragile populations are only slightly more likely to evacuate in the face of impending storms. This suggests, for these groups, there may be other factors such as …
