Low frequency radio observations of bi-directional electron beams in the solar corona

The radio signature of a shock travelling through the solar corona is known as a type II solar radio burst. In rare cases these bursts can exhibit a fine structure known as `herringbones', which are a direct indicator of particle acceleration occurring at the shock front. However, few studies have been performed on herringbones and the details of the underlying particle acceleration processes are unknown. Here, we use an image processing technique known as the Hough transform to statistically analyse the herringbone fine structure in a radio burst at $\sim$20-90 MHz observed from the Rosse Solar-Terrestrial Observatory on 2011 September 22. We identify 188 individual bursts which are signatures of bi-directional electron beams continuously accelerated to speeds of 0.16$_{-0.10}^{+0.11} c$. This occurs at a shock acceleration site initially at a constant altitude of $\sim$0.6 R$_{\odot}$ in the corona, followed by a shift to $\sim$0.5 R$_{\odot}$. The anti-sunward beams travel a distance of 170$_{-97}^{+174}$ Mm (and possibly further) away from the acceleration site, while those travelling toward the sun come to a stop sooner, reaching a smaller distance of 112$_{-76}^{+84}$ Mm. We show that the stopping distance for the sunward beams may depend on the total number density and the velocity of the beam. Our study concludes that a detailed statistical analysis of herringbone fine structure can provide information on the physical properties of the corona which lead to these relatively rare radio bursts

At the Intersection of Health and Justice: How the Health of American Indians and Alaska Natives Is Disproportionately Affected by Disparities in the Criminal Justice System

American Indian and Alaska Natives (AI/AN) are a neglected population in the United States. Their health and welfare needs are often swept aside and, because of historical treaty agreements with the United States government, they suffer disparities in the justice system and, consequently, poor health. A deep look into everyday life for an AI/AN tells a story of poverty and relatively low life expectancy, proportionately high incidences of disease, high rates of incarceration, and prolific alcohol and substance abuse. AI/ANs are incarcerated at a higher rate proportionately than their white counterparts. They experience harsher sentences, due in part to jurisdictional laws, and they are the racial group most likely to be killed by law enforcement. This paper highlights concerns about how disparities in the justice system impact the health of AI/ANs

Faculty Publication Trends in a Japanese National University’s Medical Faculty: A Preliminary Diachronic Comparison

This paper presents a diachronic analysis of publication frequency and language medium for a Japanese national university’s medical faculty. Studies of trends in global writing for academic publication tend to implicate English language publication frequency increasing at the expense of publishing in national languages (Bennet, 2014). However, while increases in English language publication have been demonstrated (Fire & Guestrin, 2019), there remains little quantitative analysis of how the language publication practices of university faculty from outside the Anglophone center of higher education have changed, with Kyvik (1990, 2003), Daizen (2015), and Huang (2015) being notable exceptions. Here we diachronically analyze publication reports for a Japanese university’s medical faculty, examining annual university publication reports across two time periods, 1979 to 1980 and 2017 to 2018 for three medical subspecialties; biochemistry, internal medicine, and pathology. Across the subspecialties, English language publication in the most prestigious publication type, original journal articles, has largely come at the expense of Japanese language publication, with Japanese publications and English publications switching places in terms of frequency of publication between 1979 to 1980 and 2017 to 2018. However, less prestigious publication types have increased for both Japanese and English, suggesting that professional communication in Japanese remains important

Not Your Mother’s PDA: The Transition from PDA Pilot to Full Acquisitions Integration

Western Libraries and Ingram Content Group worked together to establish a Patron Driven Acquisition (PDA) program that has been incorporated into the regular acquisitions workflow at Western. Some features of the program include: all titles selected for addition to the PDA collection are filtered through the approval profiles established by the librarians, the library’s holdings are uploaded to Ingram weekly so that duplicate titles are avoided, invoices for purchased PDA titles are sent weekly, and holdings for un-purchased and purchased PDA records are updated weekly. A PDA Working Group established the program at Western by meeting with collections librarians to assist with profile adjustments and ease concerns of how this method of acquisition would impact the collection. The Working Group is monitoring the program and gathering data to assess the impact of PDA. In addition to collecting information about titles loaded and titles purchased, an online survey to assess user response to e-books is continuing. Western and Ingram have continued to work together closely to ensure the program is successful and to make profile adjustments as necessary

Active Semantic Electronic Medical Record

The healthcare industry is rapidly advancing towards the widespread use of electronic medical records systems to manage the increasingly large amount of patient data and reduce medical errors. In addition to patient data there is a large amount of data describing procedures, treatments, diagnoses, drugs, insurance plans, coverage, formularies and the relationships between these data sets. While practices have benefited from the use of EMRs, infusing these essential programs with rich domain knowledge and rules can greatly enhance their performance and ability to support clinical decisions. Active Semantic Electronic Medical Record (ASEMR) application discussed here uses Semantic Web technologies to reduce medical errors, improve physician efficiency with accurate completion of patient charts, improve patient safety and satisfaction in medical practice, and improve billing due to more accurate coding. This results in practice efficiency and growth by enabling physicians to see more patients with improved care. ASEMR has been deployed and in daily use for managing all patient records at the Athens Heart Center since December 2005. This showcases an application of Semantic Web in health care, especially small clinics
