THE UNIVERSITY BELL: A RESEARCH INTO TRADITIONAL METHODS OF BELL FOUNDING

poster abstractBell manufacturing companies no longer exist in the United States that utilize traditional craft procedures or are able to tune bells to standards based on ‘true-harmonic’ formula. Most bells in the United States used in the many forms of Campanology, or bell ringing, are imported from European foundries. These European bells are made using sensibilities that have exist-ed for over 800 years. The few remaining foundries, John Taylor and Co. in England, Paccard of France, Petit Fritsen and The Royal Eijsbouts Bell Found-ry located in The Netherlands, all provided the opportunity to conduct inten-sive study into the craft of bell making. By incorporating these craft tradi-tions into a contemporary fine art practice, viewers and listeners are able to access an otherwise obsolete aspect of the history of our material culture. Following closely in the theory and manufacturing procedures of these European founders, a bell of 110 lbs. titled The University Bell was cast at the Herron School of Art and Design’s foundry. The metal for the project was sourced from a redundant bell of St. Michael’s Parish Church Cornhill, Lon-don that was originally made in 1728 by Thomas Lester, one of the original founders of our 1752 Liberty Bell. The University Bell is currently in the earliest stages of being tuned in Mooresville, Indiana for a final nominal tone of C#3 at A=440Hz. Assistance from Smith’s Bell and Clock Service Inc., Bell Expert Richard Strauss, and John Taylor and Co. are contributing to the effort. The University Bell will later be installed in a series of sight specific performances. The successful cast of The University Bell and the continuing efforts to oversee the professional creation of tuned bells in this country marks the re-turn of a historic trade whose product has long resounded the democratic overtones of liberty and freedom.

Utilizing Guided Simulation in Conjunction with Digital Learning Tools in Air Traffic Control Training to Enhance Learning at the Collegiate Level

Students in an air traffic control program are required to learn and apply advance knowledge and skills in a limited time frame. All students learn at different rates as well as through different learning styles. Swivl is a video capture tool designed to enhance student learning by allowing students to refer back to their individual classroom lab training session videos via an online portal. Swivl is being utilized in two ATC lab courses. During this research, two technological shortcomings were discovered: (1) Swivl lacks the ability to capture audio from the COA’s existing communication software and (2) Swivl cannot focus on the radar display. As a result, the videos have lacked visual clarity when reviewing the session. Consequently Swivl has been shown to be an ineffective digital learning tool for this situation. Swivl, used in conjunction with a simulated ATC tower, has proven to be effective in enhancing overall learning due to the visual nature of the tower learning environment. The nature of the tower simulator allows for better visual acuity and effective communication exchange within the Swivl videos. Once these two issues are resolved, Swivl will have the potential to be an effective tool in ATC training, and may enhance learning by allowing students to sharpen those skills necessary for advancement in the field of air traffic control

Educating Social Scholars: Examining Novice Researchers’ Practices with Social Media

Recent articles in the educational research fi eld have called for a stronger research focus on students’ learning with everyday technologies in-and-out-of classrooms and on the changing nature of scholars’ practices in light of technological advancements. We present fi ndings from a mixed methods study of whether and how novice researchers understand and practice social scholarship – a concept currently being debated in various disciplines – which seeks to leverage social media affordances to create expanded sites for research collaboration, peer review, dissemination, and evaluation of research impact. We found that novice researchers focused almost exclusively on social scholarship of discovery and much less on interdisciplinary, teaching, or applied scholarship. Insights from this study will appeal to those interested in examining the theory and design of graduate student learning and faculty development

Microultraound and small bowel inflammation:Tissue phantom studies

Capsule endoscopy represents a highly convenient but limited means of imaging inflammatory conditions of the small bowel. The inclusion of high frequency microultrasound into a capsule endoscope has the potential to enhance diagnostic capabilities with subsurface imaging of the bowel wall. Experimental studies on abattoir-obtained porcine small bowel have been carried out as an ethical means to characterize healthy and altered tissue in a preclinical setting as well as to explore other means of imaging pathology. Samples of small bowel were cannulated and perfused with phosphate buffered saline followed by variable dilutions of polystyrene microspheres. All samples were scanned with a purpose built step scanner employing a 47 MHz single element transducer. Results indicated that tissue high frequency ultrasound demonstrated sufficient sensitivity to detect the disruption normal histology with microsphere infusion. The combination of microultrasound and capsule endoscopy has the potential to enhance the diagnostic capabilities with improved qualitative and quantitative dimensions

Incorporating Digital Learning Tools in Conjunction with Air Traffic Control Simulation

Learning and applying complex information at a fast rate can be challenging for students within an air traffic control - training program. Incorporating digital learning tools into an air traffic control training programs may increase student learning and success rates. Swivl is a digital learning capture tool designed to enhance student learning by allowing students to refer back to their individual classroom lab training session videos via an online portal. Embry Riddle’s air traffic program has started using Swivl in two separate ATC courses in order to determine if it is a viable solution to increase learning. During our research, we have come to the conclusion that Swivl is most useful in the air traffic control tower simulator, and has shown to be an effective learning tool thus far from the teacher’s perspective. Additional student feedback and analysis is forthcoming . Swivl has the potential to be an effective tool in ATC training and may enhance learning by allowing students to sharpen skills that are necessary to advance in the field of air traffic control. The air traffic control - training academy (used to train air traffic controllers hired by the federal government) has a high failure rate. Incorporating digital learning tools in that setting may increase success rates as well

Applying item-response theory to the development of a screening adaptation of the Goldman-Fristoe Test of Articulation-2

PURPOSE: Item Response Theory (IRT) is a psychometric approach to measurement that uses latent trait abilities (e.g., speech sound production skills) to model performance on individual items that vary by difficulty and discrimination. An IRT analysis was applied to preschooler’s productions of the words on the Goldman-Fristoe Test of Articulation-2 (GFTA-2) to identify candidates for a screening measure of speech sound production skills. METHOD: The phoneme accuracies from 154 preschoolers, with speech skills on the GFTA-2 ranging from the 1st to above the 90th percentile, were analyzed with a two-parameter logistic model. RESULTS: A total of 108 of the 232 phonemes from stimuli in the sounds-in-words subtest fit the IRT model. These phonemes, and subgroups of the most difficult of these phonemes, correlated significantly with the children’s overall percentile scores on the GFTA-2. Regression equations calculated for the five and ten most difficult phonemes predicted overall percentile score at levels commensurate with other screening measures. CONCLUSIONS: These results suggest that speech production accuracy can be screened effectively with a small number of sounds. They motivate further research towards the development of a screening measure of children’s speech sound production skills whose stimuli consist of a limited number of difficult phonemes

“Hollywood” Hulk Hogan: Stardom, Synergy and Field Migration

During the late 1980s, World Wrestling Federation star Hulk Hogan embarked on a career as a Hollywood movie star, through roles in several modestly-budgeted films produced by New Line Cinema. Building on recent examinations of “celebrity migration” between fields and studies of “promotional culture”, we explore how Hogan’s celebrity persona adapted to various economies and structures of fame in a changing media marketplace. This article explores how Hogan negotiated of codes and conventions of different popular cultural fields and media subfields. By doing so, we identify key tensions in the wrestler’s celebrity image during the late 1980s and early 1990s and reflect on the difficulties celebrities face when trying to become film stars

Third-person self-talk facilitates emotion regulation without engaging cognitive control: Converging evidence from ERP and fMRI.

Does silently talking to yourself in the third-person constitute a relatively effortless form of self control? We hypothesized that it does under the premise that third-person self-talk leads people to think about the self similar to how they think about others, which provides them with the psychological distance needed to facilitate self control. We tested this prediction by asking participants to reflect on feelings elicited by viewing aversive images (Study 1) and recalling negative autobiographical memories (Study 2) using either I or their name while measuring neural activity via ERPs (Study 1) and fMRI (Study 2). Study 1 demonstrated that third-person self-talk reduced an ERP marker of self-referential emotional reactivity (i.e., late positive potential) within the first second of viewing aversive images without enhancing an ERP marker of cognitive control (i.e., stimulus preceding negativity). Conceptually replicating these results, Study 2 demonstrated that third-person self-talk was linked with reduced levels of activation in an a priori defined fMRI marker of self-referential processing (i.e., medial prefrontal cortex) when participants reflected on negative memories without eliciting increased levels of activity in a priori defined fMRI markers of cognitive control. Together, these results suggest that third-person self-talk may constitute a relatively effortless form of self-control
