Making Memories: A Consumer-Based Model Of Authenticity Applied To Living History Sites, Muhammet Kesgin, Babak Taheri, Rajendran S. Murthy, Juilee Decker, Martin Joseph Gannon

Articles

Purpose: Underpinned by the consumer-based model of authenticity (CBA), this study investigated whether leisure involvement, object-based and existential authenticity, host sincerity, and engagement stimulate positive memorable visitor experiences in a distinctive commercial hospitality setting: a living history site. Methodology: Quantitative data were gathered from living history site visitors (n=1004), with partial least squares structural equation modelling used to test the hypothesized relationships. Findings: The results confirm the inclusion of the hypothesized relationships between leisure involvement, sincerity, and authenticity, relative to engagement and subsequent memorability. The findings suggest that engagement can be a predictor of positive memorable experience, contingent on CBA …

Pandemic Transformation Of Teaching And Learning: Designing Pedagogy Using The Contents Of Instructors’ “Pedagogical Pantry,” Rather Than “Established Recipes.”, Sara Schley, Carol E. Marchetti

Articles

How can faculty successfully shift from a physical classroom environment to creating meaningful online learning experiences in the midst of a pandemic? Using a “kitchen pantry” metaphor, this essay suggests faculty use a “what’s in my pantry?” approach, rather than trying to replicate the in-class experience and following a previously identified “recipe.” Some faculty embrace new technology options with great gusto. Others are resistant; and still others wait until they’ve seen others use it first to consider incorporating it. This model allows for different entry points of interaction, and for different levels of experimentation, reflecting individual faculty’s strengths and capabilities. …

An Overview Of Planar Flow Casting Of Thin Metallic Glasses And Its Relation To Slot Coating Of Liquid Films, Eric A. Theisen, Steven J. Weinstein

Articles

Planar flow casting (PFC) is a method that can be used to make thin, long, and wide metallic alloy foils by extruding molten liquid through a thin and wide nozzle and immediately quenching on a moving roller. The quenching rates are high enough that amorphous metallic glasses may be formed which have many desirable properties for a wide variety of applications. This paper reviews how PFC processes were developed, examines the typical operability range of PFC, and reviews the defects that commonly form. The geometrical similarities between PFC and slot coating process are apparent, and this paper highlights differences between …

A Health Elearning Ontology And Procedural Reasoning Approach For Developing Personalized Courses To Teach Patients About Their Medical Condition And Treatment, Martin Michalowski, Szymon Wilk, Wojtek Michalowski, Dympna O'Sullivan, Silvia Bonaccio, Enea Parimbelli, Marc Carrier, Grégoire Le Gal, Stephen Kingwell, Mor Peleg

Articles

We propose a methodological framework to support the development of personalized courses that improve patients’ understanding of their condition and prescribed treatment. Inspired by Intelligent Tutoring Systems (ITSs), the framework uses an eLearning ontology to express domain and learner models and to create a course. We combine the ontology with a procedural reasoning approach and precompiled plans to operationalize a design across disease conditions. The resulting courses generated by the framework are personalized across four patient axes—condition and treatment, comprehension level, learning style based on the VARK (Visual, Aural, Read/write, Kinesthetic) presentation model, and the level of understanding of specific …

Locating Identities In Time: An Examination Of The Impact Of Temporality On Presentations Of The Self Through Location-Based Social Networks, Konstantinos Papangelis, Ioanna Lykourentzou, Vassilis-Javed Khan, Alan Chamberlain, Ting Cao, Micahel Saker, Nicolas Lalone

Articles

Studies of identity and location-based social networks (LBSN) have tended to focus on the performative aspects associated with marking one’s location. Yet, these studies often present this practice as being an a priori aspect of locative media. What is missing from this research is a more granular understanding of how this process develops over time. Accordingly, we focus on the first six weeks of 42 users beginning to use an LBSN we designed and named GeoMoments. Through our analysis of our users' activities, we contribute to understanding identity and LBSN in two distinct ways. First, we show how LBSN users …

Antiracist Remedial Approaches In Judge Gregory’S Jurisprudence, Leah M. Litman

Articles

This piece uses the idea of antiracism to highlight parallels between school desegregation cases and cases concerning errors in the criminal justice system. There remain stark, pervasive disparities in both school composition and the criminal justice system. Yet even though judicial remedies are an integral part of rooting out systemic inequality and the vestiges of discrimination, courts have been reticent to use the tools at their disposal to adopt proactive remedial approaches to address these disparities. This piece uses two examples from Judge Roger Gregory’s jurisprudence to illustrate how an antiracist approach to judicial remedies might work.

Biochemical Impact Of Solar Radiation Exposure On Human Keratinocytes Monitored By Raman Spectroscopy; Effects Of Cell Culture Environment, Ulises Lopez Gonzalez, Alan Casey, Hugh Byrne

Articles

Understanding and amelioration of the effects of solar radiation exposure are critical in preventing the occurrence of skin cancer. Towards this end, many studies have been conducted in 2D cell culture models under simplified and unrealistic conditions. 3D culture models better capture the complexity of in vivo physiology, although the effects of the 3D extracellular matrix have not been well studied. Monitoring the instantaneous and resultant cellular responses to exposure, and the influence of the 3D environment, could provide an enhanced understanding of the fundamental processes of photocarcinogenesis. This work presents an analysis of the biochemical impacts of simulated solar …

Bursting The Auto Loan Bubble In The Wake Of Covid-19, Pamela Foohey

Articles

Before the COVID-19 pandemic, auto loans outstanding in the United States had soared to record highs. The boom in lending spanned new and used cars and traditional and subprime loans. With loan delinquencies also hitting new highs almost every quarter, predictions that the auto lending market could burst soon abounded. When the economy came to a grinding halt and unemployment skyrocketed in the wake of the pandemic, auto lenders knew they were facing a crisis. Throughout 2020, auto lenders granted more payment forbearances to consumers, while slashing interest rates on new loans. Auto manufacturers similarly made promises to buyers, such …

Food And The Irish Short Story Imagination, Anke Klitzing

Articles

Short fiction is a format heartily embraced by the Irish literary imagination since the nineteenth century. This paper takes a gastrocritical approach to investigate the role of food in selected stories from the recently published anthology The Art of the Glimpse (2020). It shows that through the years, food and foodways have been valuable tools for Irish writers, providing setting and context, themes and symbols, plot points, conflicts, characterisation, as well as the quintessential epiphanies.

A Rare Case Of Jejunal Perforation Due To Post-Transplant Lymphoproliferative Disease 27 Years After Liver Transplant, Marcos Rosado, Thomas Serena, Zophia Martinez, Erich Schwartz, Harris Mainster

Articles

Post-transplant lymphoproliferative disease (PTLD) is a well-known post-transplant malignancy common in both solid organ and stem cell transplants. The incidence of PTLD in adult liver transplant recipients is approximately 2.8%. While most often presenting in the first year after transplant, PTLD can occur at any time. This case report narrates a 61-year-old female with a history of liver transplant in 1992 for autoimmune hepatitis that was found to have a jejunal perforation due to PTLD 27 years later. The patient presented to the hospital with a fifteen hour history of left sided abdominal pain that was progressively worsening. The patient …

Research activity in autonomous drone navigation has increased rapidly in the past five years, and drones are moving fast towards the ultimate goal of near-complete autonomy. However, while much work in the area focuses on specific tasks in drone navigation, the contribution to the overall goal of autonomy is often not assessed, and a comprehensive overview is needed. In this work, a taxonomy of drone navigation autonomy is established by mapping the definitions of vehicular autonomy levels, as defined by the …

1d Conditional Generative Adversarial Network For Spectrum-To-Spectrum Translation Of Simulated Chemical Reflectance Signatures, Cara Murphy, John Kerekes

Articles

The classification of trace chemical residues through active spectroscopic sensing is challenging due to the lack of physics-based models that can accurately predict spectra. To overcome this challenge, we leveraged the field of domain adaptation to translate data from the simulated to the measured domain for training a classifier. We developed the first 1D conditional generative adversarial network (GAN) to perform spectrum-to-spectrum translation of reflectance signatures. We applied the 1D conditional GAN to a library of simulated spectra and quantified the improvement in classification accuracy on real data using the translated spectra for training the classifier. Using the GAN-translated library, …

Adapting An Agent-Based Model Of Infectious Disease Spread In An Irish County To Covid-19, Elizabeth Hunter, John D. Kelleher

Articles

The dynamics that lead to the spread of an infectious disease through a population can be characterized as a complex system. One way to model such a system, in order to improve preparedness, and learn more about how an infectious disease, such as COVID-19, might spread through a population, is agent-based epidemiological modelling. When a pandemic is caused by an emerging disease, it takes time to develop a completely new model that captures the complexity of the system. In this paper, we discuss adapting an existing agent-based model for the spread of measles in Ireland to simulate the spread of …

Deal Protection Devices, Albert H. Choi

Articles

In mergers and acquisitions transactions, a buyer and a seller will often agree to contractual mechanisms (deal protection devices) to deter third parties from jumping the deal and to compensate a disappointed buyer. With the help of auction theory, this Article analyzes various deal protection devices, while focusing on the two most commonly used mechanisms: match rights and target termination fees. A match right gives the buyer a right to “match” a third party’s offer so as to prevent the third party from snatching the target away, while a termination fee compensates the buyer when a third party acquires the …

Pivot Points In Bivariate Linear Regression, David L. Farnsworth, Carl V. Lutzer

Articles

There are little-noticed points in the plane, which are artifacts of linear regression. The points, which are called pivot points, are the intersections of sets of regression lines. We derive the coordinates of the pivot point and explain its sources. We show how a pivot point arises in a certain notable data set, which has been analyzed often for points of high leverage. We obtain the application of pivot points that shortens calculations when updating a set of bivariate observations by adding a new point.

A Geometric Approach To Conditioning And The Search For Minimum Variance Unbiased Estimators, David L. Farnsworth, James E. Marengo

Articles

Our purpose is twofold: to present a prototypical example of the conditioning technique to obtain the best estimator of a parameter and to show that this technique resides in the structure of an inner product space. The technique uses conditioning of an unbiased estimator on a sufficient statistic. This procedure is founded upon the conditional variance formula, which leads to an inner product space and a geometric interpretation. The example clearly illustrates the dependence on the sampling methodology. These advantages show the power and centrality of this process.

Temperature-Sensitive Holograms With Switchable Memory, Muhammad Irfan Dr, Suzanne Martin Dr, Izabela Naydenova Prof

Articles

Abstract

Herein, the dynamics and reversibility of temperature-induced changes in volume phase holographic gratings (VPHGs) recorded in the low-toxicity self-processing photopolymer poly(N-isopropyl acrylamide) (poly-NIPA) are reported on. Transmission and reflection gratings are exposed to temperatures ranging 8–60 °C to study the effect of temperature on their properties. First, the role of the photopolymer chemical composition is investigated by comparing layers containing NIPA with those containing acrylamide (AA) and measuring the normalized diffraction efficiency (DE) at 60 °C; higher thermal sensitivity is observed for poly-NIPA gratings (24% drop) versus low sensitivity for AA gratings (2% increase). The impact of …

Raman Spectroscopic Characterisation Of Non Stimulated And Stimulated Human Whole Saliva, Genecy Calado, Isha Behl, Hugh Byrne, Fiona Lyng

Articles

Human saliva is a unique biofluid which can reflect the physiopathological state of an individual. The wide spectrum of molecules present in saliva, compounded by the close association of salivary composition to serum metabolites, can provide valuable information for clinical diagnostic applications through highly sensitive vibrational spectroscopic techniques such as Raman spectroscopy. However, the nature of saliva, in terms of collection and patient-related characteristics, can be considered factors which may strongly affect the Raman spectral profile of salivary samples and disrupt the search for specific salivary biomarkers in the detection of diseases. The main objective of this study was to …

Mining And Managing Big Data Refactoring For Design Improvement: Are We There Yet?, Eman Abdullah Alomar, Mohamed Wiem Mkaouer, Ali Ouni
