Agora Teaching App
Professional development of teachers normally ends after formal collegiate education. Agora desires to help educators continually train, to learn the skills of good teaching in classrooms by using various, non-traditional methodologies. By translating Agoras current platform to an app, Agora can widen their scope and serve Latin American countries outside of Peru, where they are currently based. We will simply take their current business and course platform and provide a mobile user interface for it. By expanding the reach of Agora, Latin American teachers will be well equipped to teach their classes with innovation and effectiveness
Heritage Language and Culture: The Cleveland Slovenian Experience
Slovenians have played an important role in the history of Cleveland. From their origins being centered around St. Clair Avenue to their more dispersed state today, Cleveland is home to the largest population of Slovenians outside of Slovenia itself. Our study sought to explore the differences and similarities between native and heritage Slovenians. For data collection we used the picture word recognition test, sentence acceptability judgements test, and the cultural questionnaire. We designed these tests to study the Slovenian Clevelander community and shed on the understudied subjects of “heritage linguistics” and “language attrition”. Heritage speakers, or speakers that learned a language from family and outside of the country that it is spoken, are a unique group of people who have traits of both first and second language ability levels. Language attrition is a phenomena in which a language is definitively a first language but one begins to commit errors which they would not if they had stayed in an environment of only their own native language. These phenomena are fascinating and our data reflects the effects American English language and culture have caused on the language and culture of Cleveland Slovenians, previously unknown in the field of Linguistics.https://engagedscholarship.csuohio.edu/u_poster_2017/1004/thumbnail.jp

Bottomonium spectral widths at nonzero temperature using maximum likelihood
We present progress results from the Fastsum collaboration’s programme to determine the spectrum of the bottomonium system as a function of temperature using a variety of approaches. Inthese proceedings, the Maximum Likelihood approach is used with an Ansatz comprising of a Gaussian spectral function for the ground state. Fastsum anisotropic lattices with 2 + 1 dynamicalquark flavours were used with temperatures ranging from 47 to 375 MeV
Challenging dyke ascent models using novel laboratory experiments: Implications for reinterpreting evidence of magma ascent and volcanism
Volcanic eruptions are fed by plumbing systems that transport magma from its source to the surface, mostly fed by dykes. Here we present laboratory experiments that model dyke ascent to eruption using a tank filled with a crust analogue (gelatine, which is transparent and elastic) that is injected from below by a magma analogue (dyed water). This novel experimental setup allows, for the first time, the simultaneous measurement of fluid flow, sub-surface and surface deformation during dyke ascent. During injection, a penny-shaped fluid-filled crack is formed, intrudes, and traverses the gelatine slab vertically to then erupt at the surface. Polarised light shows the internal stress evolution as the dyke ascends, and an overhead laser scanner measures the surface elevation change in the lead-up to dyke eruption. Fluorescent passive-tracer particles that are illuminated by a laser sheet are monitored, and the intruding fluid's flow dynamics and gelatine's sub-surface strain evolution is measured using particle image velocimetry and digital image correlation, respectively. We identify 4 previously undescribed stages of dyke ascent. Stage 1, early dyke growth: the initial dyke grows from the source, and two fluid jets circulate as the penny-shaped crack is formed. Stage 2, pseudo-steady dyke growth: characterised by the development of a rapidly uprising, central, single pseudo-steady fluid jet, as the dyke grows equally in length and width, and the fluid down-wells at the dyke margin. Sub-surface host strain is localised at the head region and the tail of the dyke is largely static. Stage 3, pre-eruption unsteady dyke growth: an instability in the fluid flow appears as the central fluid jet meanders, the dyke tip accelerates towards the surface and the tail thins. Surface deformation is only detected in the immediate lead-up to eruption and is characterised by an overall topographic increase, with axis-symmetric topographic highs developed above the dyke tip. Stage 4 is the onset of eruption, when fluid flow is projected outwards and focused towards the erupting fissure as the dyke closes. A simultaneous and abrupt decrease in sub-surface strain occurs as the fluid pressure is released. Our results provide a comprehensive physical framework upon which to interpret evidence of dyke ascent in nature, and suggest dyke ascent models need to be re-evaluated to account for coupled intrusive and extrusive processes and improve the recognition of monitoring signals that lead to volcanic eruptions in nature
Sustaining allied health telehealth services beyond the rapid response to COVID-19 : Learning from patient and staff experiences at a large quaternary hospital
The patient, clinician and administration staff perspectives of telehealth (specifically videoconferencing) services provided by Allied Health Professions (AHP) at a large quaternary hospital were explored. The purpose was to understand stakeholders’ perceptions of the service during initial COVID-19 restrictions and examine factors that influenced the implementation and sustained use of telehealth. A sequential mixed-methods approach was undertaken. Stage 1 involved surveys completed by patients (n = 109) and clinicians (n = 66) who received and provided care via telehealth, respectively, across six AHP departments. Stage 2 involved focus groups with clinicians (n = 24) and administrative staff (n = 13) to further examine implementation and sustainability factors.
All participant groups confirmed that telehealth was a valid service model and valued the benefits it afforded, particularly during COVID-19 restrictions. Both patients and clinicians reported that not all AHP services could be delivered via telehealth and preferred a blended model of telehealth and in-person care. Increased administrative staff assistance was needed to support growing telehealth demand. Main factors to address are the need to expand AHP telehealth models and workforce/patient training, improve workflow processes and enhance technical support.
Despite rapid implementation, telehealth experiences were overall positive. Study findings are being used to generate solutions to enhance and sustain AHP telehealth services
Radiation Performance of Commercial SiGe HBT BiCMOS-High Speed Operational Amplifiers
We present results on heavy-ion and proton irradiations for commercial SiGe BiCMOS operational amplifiers: LTC6400-20 from Linear Technology and THS4304 from Texas Instruments. We found that the devices are susceptible to heavy-ion-induced SETs. The SET cross-sections increase with increasing operating frequency. The LTC6400 exhibits a LET(sub th) < 7.4 MeVsq cm/mg for frequencies ranging from 10 to 1000 MHz. The THS4304 exhibits a LET(sub th) < 4.4 MeVsq cm/mg at 200 MHz; the LET(sub th) decreases with increasing frequency. The significance of the SETs also increases with frequency. The SETs at 1000 MHz can erase several signal cycles. We al.so found that the LTC6400 is relatively robust against 198 and 54 MeV protons. We did not observe angular sensitivity from the proton irradiations
