Reality Check: Instructing Patrons in CD-ROM Use

This is a two-part presentation given by reference librarians Rochelle Ballard and Meg Scharf. Meg first described UCF’s new CD-ROM services. Patron expectations were very high. Although a great deal of assistance was sometimes needed, patrons wanted to be able to search autonomously, which meant they needed instruction. Instruction was delivered to individual patrons at the time of need; through demonstrations held in the area that housed the CD Rooms; in workshops; and in the regular instruction classes delivered by librarians to students at the request of teaching faculty members. Rochelle, who was instrumental in establishing UCF’s end-user services with CD-ROMs, and later with online databases and the Internet, then gave the most important part of the presentation: how UCF librarians learned about searching the 13 CD-ROM databases, and the writing and use of “How to Search” handouts. New CD-ROMs were held back from the Reference floor, so librarians could learn to use them before they fielded questions from students, faculty, and community patrons. She describes workshops held for users in the Bibliographic Instruction classroom. Rochelle, UCF’s expert on the CD-ROMs at the time, describes getting “the shakes at the thought of a new CD-ROM with a different search system.” Some librarians in the audience came from libraries with no CD-ROMs available, and others were at the beginning of offering them to patrons. So while this presentation seems very elementary, at that time it was regarded as a bit “cutting edge”

Crystal-Size Effects on Carbon Dioxide Capture of a Covalently Alkylamine-Tethered Metal-Organic Framework Constructed by a One-Step Self-Assembly

To enhance the carbon dioxide (CO2) uptake of metal-organic frameworks (MOFs), amine functionalization of their pore surfaces has been studied extensively. In general, amine-functionalized MOFs have been synthesized via post-synthetic modifications. Herein, we introduce a one-step construction of a MOF ([(NiLethylamine)(BPDC)]=MOFNH2; [NiLethylamine]2+=[Ni(C12H32N8)]2+; BPDC2-=4,4???-biphenyldicarboxylate) possessing covalently tethered alkylamine groups without post-synthetic modification. Two-amine groups per metal centre were introduced by this method. MOFNH2 showed enhanced CO2 uptake at elevated temperatures, attributed to active chemical interactions between the amine groups and the CO2 molecules. Due to the narrow channels of MOFNH2, the accessibility to the channel of CO2 is the limiting factor in its sorption behaviour. In this context, only crystal size reduction of MOFNH2 led to much faster and greater CO2 uptake at low pressures.open

The retrospective analysis of Antarctic tracking data project

The Retrospective Analysis of Antarctic Tracking Data (RAATD) is a Scientific Committee for Antarctic Research project led jointly by the Expert Groups on Birds and Marine Mammals and Antarctic Biodiversity Informatics, and endorsed by the Commission for the Conservation of Antarctic Marine Living Resources. RAATD consolidated tracking data for multiple species of Antarctic meso- and top-predators to identify Areas of Ecological Significance. These datasets and accompanying syntheses provide a greater understanding of fundamental ecosystem processes in the Southern Ocean, support modelling of predator distributions under future climate scenarios and create inputs that can be incorporated into decision making processes by management authorities. In this data paper, we present the compiled tracking data from research groups that have worked in the Antarctic since the 1990s. The data are publicly available through biodiversity.aq and the Ocean Biogeographic Information System. The archive includes tracking data from over 70 contributors across 12 national Antarctic programs, and includes data from 17 predator species, 4060 individual animals, and over 2.9 million observed locations

Breast MRI BI-RADS Assessments and Abnormal Interpretation Rates by Clinical Indication in US Community Practices

RATIONALE AND OBJECTIVES: As breast MRI use grows, benchmark performance parameters are needed for auditing and quality assurance purposes. We describe the variation in breast MRI abnormal interpretation rates (AIRs) by clinical indication among a large sample of U.S. community practices. MATERIALS AND METHODS: We analyzed data from 41 facilities across five Breast Cancer Surveillance Consortium imaging registries. Each registry obtained IRB approval for this HIPAA compliant analysis. We included 11,654 breast MRI exams conducted in 2005–2010 among women aged 18–79 years. We categorized clinical indications as: 1) screening; 2) extent of disease; 3) diagnostic (e.g., breast symptoms); and 4) other (e.g., short-interval follow-up). We characterized assessments as positive (i.e., BI-RADS 0, 4, and 5) or negative (i.e., BI-RADS 1, 2, 6), and provide results with BI-RADS 3 categorized as positive and as negative. We tested for differences in AIRs across clinical indications both unadjusted and adjusted for patient characteristics and registry, and assessed for changes in AIRs by indication over time. RESULTS: When categorizing BI-RADS 3 as positive, AIRs were 21.0% (95% CI: 19.8, 22.3) for screening, 31.7% (95% CI: 29.6, 33.8) for extent of disease, 29.7% (95% CI: 28.3, 31.1) for diagnostic, and 27.4% (95% CI: 25.0, 29.8) for other indications (p<0.0001). When categorizing BI-RADS 3 as negative, AIRs were 10.5% (95% CI: 9.5, 11.4) for screening, 21.8% (95% CI: 19.9, 23.6) for extent of disease, 17.7% (95% CI: 16.5, 18.8) for diagnostic, and 13.3% (95% CI: 11.6, 15.2) for other indications (p<0.0001). The significant differences in AIRs by indication persisted even after adjusting for patient characteristics and registry (p<0.0001). In addition, for most indications, there were no significant changes in AIRs over time. CONCLUSION: Breast MRI AIRs differ significantly by clinical indication. Practices should stratify breast MRI exams by indication for quality assurance and auditing purposes
