Frameworking CRAAP: How We\u27re Correlating the ACRL Framework to Content Evaluation with the CRAAP Test in Our Instruction Practices

For years, we have used the CRAAP Test as an information evaluation mechanism in our instruction sessions. We apply it to everyday, real-life stories, and to complex research as needed. Currently, we are adapting our practices of CRAAP Test instruction by expanding the evaluation to include the ACRL Framework for Information Literacy for Higher Education. Specifically, we have given each CRAAP letter a frame for discussion when evaluating. This presentation will cover what frames we have assigned to each letter, why, and the assessment of the instruction using these concepts

transformations in the nuclear and bioenergy sectors in Sweden, Brazil, and the United States

Most of the controversies surrounding how to structure climate change mitigation and adaptation – including financing, what counts as action, and how to measure progress against uncertain goals – have technological change as an underlying assumption. Technological transformation is at the heart of mitigation in the energy system, and technological change (cultivars and management) will be a prime contributor to mitigation and adaptation in agriculture and water. Therefore, the issue of governing the diffusion of GEC- related technology is critically important. The standard analyses that assume we just need to “get the prices right” are insufficient in a world where markets are at best imperfect and equitable well-being is as much a goal as efficiency. Our research examines the ways in technological change is guided by such governance factors as governments (regulation and policy), firms with existing expertise and infrastructure, international and national needs for security, innovation networks, and leadership. We will illustrate the determinative nature of these governance factors through case studies of two major energy technologies – nuclear power and biofuels – in three countries – Brazil, Sweden, and the United States. Primary data comes from interviews with policymakers and firm managers who have been involved in these changes in the three countries. Open-ended and structured questions about a range of driving or enabling factors allow us to establish one or more configurations of factors that can inform the governance of future technological change related to mitigation and serve as the basis for further research into technological change related to adaptation

The medicine hat block and the early paleoproterozoic assembly of Western Laurentia

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. The accretion of the Wyoming, Hearne, and Superior Provinces to form the Archean core of western Laurentia occurred rapidly in the Paleoproterozoic. Missing from Hoffman’s (1988) original rapid aggregation model was the Medicine Hat block (MHB). The MHB is a structurally distinct, complex block of Precambrian crystalline crust located between the Archean Wyoming Craton and the Archean Hearne Province and overlain by an extensive Phanerozoic cover. It is distinguished on the basis of geophysical evidence and limited geochemical data from crustal xenoliths and drill core. New U‐Pb ages and Lu‐Hf data from zircons reveal protolith crystallization ages from 2.50 to 3.28 Ga, magmatism/metamorphism at 1.76 to 1.81 Ga, and εHfT values from −23.3 to 8.5 in the Archean and Proterozoic rocks of the MHB. These data suggest that the MHB played a pivotal role in the complex assembly of western Laurentia in the Paleoproterozoic as a conjugate or extension to the Montana Metasedimentary Terrane (MMT) of the northwestern Wyoming Province. This MMT–MHB connection likely existed in the Mesoarchean, but it was broken sometime during the earliest Paleoproterozoic with the formation and closure of a small ocean basin. Closure of the ocean led to formation of the Little Belt arc along the southern margin of the MHB beginning at approximately 1.9 Ga. The MHB and MMT re‐joined at this time as they amalgamated into the supercontinent Laurentia during the Great Falls orogeny (1.7–1.9 Ga), which formed the Great Falls tectonic zone (GFTZ). The GFTZ developed in the same timeframe as the better‐known Trans‐Hudson orogen to the east that marks the merger of the Wyoming, Hearne, and Superior Provinces, which along with the MHB, formed the Archean core of western Laurentia

Experimental Validation of Methods for Prophylaxis against Deep Venous Thrombosis: A Review and Proposal

The experimental procedure by which the valve cusp hypoxia (VCH) hypothesis of the etiology of deep venous thrombosis (DVT) was confirmed lends itself to testing of methods of prophylaxis. Similar animal experiments could end the present exclusive reliance on statistical analysis of data from large patient cohorts to evaluate prophylactic regimes. The reduction of need for such (usually retrospective) analyses could enable rationally-based clinical trials of prophylactic methods to be conducted more rapidly, and the success of such trials would lead to decreased incidences of DVT-related mortality and morbidity. This paper reviews the VCH hypothesis (“VCH thesis”, following its corroboration) and its implications for understanding DVT and its sequelae, and outlines the experimental protocol for testing prophylactic methods. The advantages and limitations of the protocol are briefly discussed

Rigorous and Practical Proportional-fair Allocation for Multi-rate Wi-Fi

Recent experimental studies confirm the prevalence of the widely known performance anomaly problem in current Wi-Fi networks, and report on the severe network utility degradation caused by this phenomenon. Although a large body of work addressed this issue, we attribute the refusal of prior solutions to their poor implementation feasibility with off-the-shelf hardware and their impre- cise modelling of the 802.11 protocol. Their applicability is further challenged today by very high throughput enhancements (802.11n/ac) whereby link speeds can vary by two orders of magnitude. Unlike earlier approaches, in this paper we introduce the first rigorous analytical model of 802.11 stations’ throughput and airtime in multi-rate settings, without sacrificing accuracy for tractability. We use the proportional-fair allocation criterion to formulate network utility maximisation as a con- vex optimisation problem for which we give a closed-form solution. We present a fully functional light-weight implementation of our scheme on commodity access points and evaluate this extensively via experiments in a real deployment, over a broad range of network conditions. Results demonstrate that our proposal achieves up to 100% utility gains, can double video streaming goodput and reduces TCP download times by 8x
