Conversion Of Australian Food Composition Data From Ausnut1999 To 2007 In The Clinical Trial Context, Elizabeth P. Neale, Yasmine C. Probst, Rebecca Thorne, Qingsheng Zhang, Jane E. O'Shea, Marijka J. Batterham, Linda C. Tapsell

Dr Marijka Batterham

An Australian food composition database, AUSNUT1999, does not include long chain omega-3 polyunsaturated fatty acid (LC omega-3 PUFA) data. Measurement of the fatty acid content of diets initially analysed using AUSNUT1999 requires conversion to AUSNUT2007, an updated database inclusive of LC omega-3 PUFA. The aim of this study was to convert clinical trial dietary data from AUSNUT1999 to AUSNUT2007 and measure LC omega-3 PUFA intake. Clinical trial diet history (DH) data was converted from AUSNUT1999 to 2007 using a staged approach. Macronutrient intake from AUSNUT1999 and 2007 were calculated and compared via paired t-tests and Wilcoxon Signed Ranks tests. Mean …

Effortless Building Census, Sam Kome Jun 2015

Effortless Building Census, Sam Kome

Library Staff Publications and Research

Library headcounts are tedious, time-consuming, and subject to the vagaries of scheduling, attention to detail, and incomplete (especially for consortia). If we conduct them perfectly, on-schedule without fail we can gather at best the number of patrons seated in various areas of the library at two arbitrary times per day. We don't know their home campus. We don't know how patronage varies by time of day. If only there was an automatic way of conducting counts that was automatic, unsleeping, and could differentiate between campuses The wireless infrastructure is (hopefully) always on, and devices are nearly ubiquitous, and typically signed …

Aspiring To Excellence: Maximising Data To Sustain, Shift And Reshape A Library For The Future, Margie H. Jantti

Margie Jantti

Perhaps more than ever before, libraries face the challenge of excelling during uncertain times. As library leaders, we have a responsibility to ensure our libraries are reputed as relevant, visible, valued and contemporary. It is imperative that we seek out new methods for maximizing the data that we are invested in and make it more readily accessible and comprehensible to key stakeholders: the senior leadership teams of the library and those of the institution. Yet where does the persuasive evidence lay to demonstrate outcomes aligned to the institution's aims? It is unlikely that library data on its own will be …


The Nine Circles Of Surveillance Hell: An Institutional View Of Information Flows And Information Threats In Libraries, Seeta Peña Gangadharan, Bonnie Tijerina May 2015

The Nine Circles Of Surveillance Hell: An Institutional View Of Information Flows And Information Threats In Libraries, Seeta Peña Gangadharan, Bonnie Tijerina

LACUNY Institute 2015

In the past few years, libraries have started to design public programs that educate patrons about different tools and techniques to protect personal privacy. But do end user solutions provide adequate safeguards against surveillance by corporate and government actors? What does a comprehensive plan for privacy entail in order that libraries live up to their privacy values? In this paper, the authors discuss the complexity of surveillance architecture that the library institution might confront when seeking to defend the privacy rights of patrons. This architecture consists of three main parts: physical or material aspects, logical characteristics, and social factors of …

Library Privacy Policies In 2015: Strategies For Renewed Relevance, Percy Wise May 2015

Library Privacy Policies In 2015: Strategies For Renewed Relevance, Percy Wise

LACUNY Institute 2015

In recent decades, library associations have advocated for the adoption of privacy and confidentiality policies as practical support to the Library Code of Ethics with a threefold purpose to (1) define and uphold privacy practices within the library, (2) convey privacy practices to patrons and, (3) protect against potential liability and public relations problems. The adoption of such policies has been instrumental in providing libraries with effective responses to surveillance initiatives such as warrantless requests and the USA PATRIOT ACT.

Nevertheless, as reflected in recent news stories, the rapid emergence of data brokerage relationships and technologies and the increasing need …

Error Correlation Between Co2 And Co As Constraint For Co2 Flux Inversions Using Satellite Data, H Wang, D J. Jacob, M Kopacz, D B. A Jones, P Suntharalingam, J A. Fisher, R Nassar, S Pawson, J E. Nielsen Feb 2015

Error Correlation Between Co2 And Co As Constraint For Co2 Flux Inversions Using Satellite Data, H Wang, D J. Jacob, M Kopacz, D B. A Jones, P Suntharalingam, J A. Fisher, R Nassar, S Pawson, J E. Nielsen

Jenny A Fisher

Inverse modeling of CO2 satellite observations to better quantify carbon surface fluxes requires a chemical transport model (CTM) to relate the fluxes to the observed column concentrations. CTM transport error is a major source of uncertainty. We show that its effect can be reduced by using CO satellite observations as additional constraint in a joint CO2-CO inversion. CO is measured from space with high precision, is strongly correlated with CO2, and is more sensitive than CO2 to CTM transport errors on synoptic and smaller scales. Exploiting this constraint requires statistics for the CTM transport error correlation between CO2 and CO, …


Using Assessment To Leverage Collaboration With The Campus Writing Center, Heidi Gauder, Hector Escobar Feb 2015

Using Assessment To Leverage Collaboration With The Campus Writing Center, Heidi Gauder, Hector Escobar

Hector Escobar

Purpose

Like many academic libraries, the University of Dayton’s Roesch Library houses a writing center. Currently located on the Library’s 2nd floor, it will soon move and become integrated with the library’s reference service. Since the writing center operates independently from the library (e.g., it is staffed by students and reports to different campus administrators), the library reference team, comprised of tenure-line faculty librarians, wanted to better understand writing center services. Given that research and writing are often intertwined, the library was particularly interested in learning how the writing center addressed the evaluation, integration and attribution of sources, tasks similar …

The "Bring Your Own Device" Conundrum For Organizations And Investigators: An Examination Of The Policy And Legal Concerns In Light Of Investigatory Challenges, Carla J. Utter, Alan Rea

Journal of Digital Forensics, Security and Law

In recent years, with the expansion of technology and the desire to downsize costs within the corporate culture, the technology trend has steered towards the integration of personally owned mobile devices (i.e. smartphones) within the corporate and enterprise environment. The movement, known as “Bring Your Own Device” (hereinafter referred to as “BYOD”), seeks to minimize or eliminate the need for two separate and distinct mobile devices for one employee. While taken at face value this trend seems favorable, the corporate policy and legal implications of the implementation of BYOD are further complicated by significant investigatory issues that far outweigh the …

Streaming Physiological Data: General Public Perceptions Of Secondary Use And Application To Research In Neonatal Intensive Care, Carolyn P. Mcgregor, Jennifer A. Heath, Yvonne Choi

Senior Deputy Vice-Chancellor and Deputy Vice-Chancellor (Education) - Papers

High speed physiological data represents one of the most untapped resources in healthcare today and is a form of Big Data. Physiological data is captured and displayed on a wide range of devices in healthcare environments. Frequently this data is transitory and lost once initially displayed. Researchers wish to store and analyze these datasets, however, there is little evidence of any engagement with citizens regarding their perceptions of physiological data capture for secondary use. This paper presents the findings of a self-administered household survey (n=165, response rate = 34%) that investigated Australian and Canadian citizens' perceptions of such physiological data …

Age-Depth Model Of The Past 630 Kyr For Lake Ohrid (Fyrom/Albania) Based On Cyclostratigraphic Analysis Of Downhole Gamma Ray Data, Henrike Baumgarten, Thomas Wonik, D C. Tanner, Alexander Francke, Bernd Wagner, Giovanni Zanchetta, Roberto Sulpizio, Biagio Giaccio, Sebastien Nomade

Faculty of Science, Medicine and Health - Papers: part A

Gamma ray (GR) fluctuations and potassium (K) values from downhole logging data obtained in the sediments of Lake Ohrid from 0 to 240 m below lake floor (b.l.f). correlate with fluctuations in δ18O values from the global benthic isotope stack LR04 (Lisiecki and Raymo, 2005). GR and K values are considered a reliable proxy to depict glacial-interglacial cycles, with high clastic input during cold and/or drier periods and high carbonate precipitation during warm and/or humid periods at Lake Ohrid. Spectral analysis was applied to investigate the climate signal and evolution over the length of the borehole. Linking downhole logging data …

Faculty of Engineering and Information Sciences - Papers: Part A

Background: Deep-sequencing allows for an in-depth characterization of sequence variation in complex populations. However, technology associated errors may impede a powerful assessment of low-frequency mutations. Fortunately, base calls are complemented with quality scores which are derived from a quadruplet of intensities, one channel for each nucleotide type for Illumina sequencing. The highest intensity of the four channels determines the base that is called. Mismatch bases can often be corrected by the second best base, i.e. the base with the second highest intensity in the quadruplet. A virus variant model-based clustering method, ViVaMBC, is presented that explores quality scores and second …
