Transcending Institutions And Borders: 21st Century Digital Scholarship At K-State, Rebel Cummings-Sauls, Rachel Miles, Ryan Otto, Charlene N. Simser
Rebel Cummings-Sauls
Digital scholarship of the 21st century transcends institutions and borders with its freedom from print and physical locations. This case study reviews aspects of establishing a sustainable digital scholarship center, supporting open access through the institutional repository (K-State Research Exchange - K-REx) and an open access publishing platform (New Prairie Press – NPP) along with other outreach efforts. The Center for the Advancement of Digital Scholarship (CADS) at K-State Libraries serves our campus community, but digital scholarship extends K-State's impact far beyond Manhattan, Kansas. Highlighting the scholarship at our campus is only one small piece of the landscape. Collaboration on …

Social Explorer is a mapping and data visualization program that creates custom maps, reports, and presentations from a wide array of survey sources, including the U.S. census, the American Community Survey, FBI Uniform Crime Reports, and some international sources such as the World Bank’s development indicators. Though most of its underlying data are published free of charge by nonprofit and government agencies, Social Explorer adds interpretative value by turning complex data into visual abstractions that aid comprehension. Furthermore, Explorer’s presentation and report options help users to compare and contrast data or put them into sociohistorical context, and all through an …

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 …

Dr Marijka Batterham
Background Chronic disease risk on a population level can be quantified through health surveys, either continuous or periodic. To date, information gathered from primary care interactions, using sentinel sites, has not been investigated as a potentially valuable surveillance system in Australia. Methods A pilot study was conducted in a single General Practice in a regional area of New South Wales, Australia to assess the feasibility of accessing data obtained through a computerised chronic disease management program that has been designed for desktop application (Pen Computer Systems (PCS) Clinical Audit Tool: ™ PCS CAT). Collated patient data included information on chronic …

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

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
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 …

Anthony A Espinoza Mr
The paper presents a comparative study performed by the Centre of Medical Radiation Physics (CMRP) on three multichannel Data Acquisition Systems (DAQ) based on different analogue front-ends to suit a wide range of radiotherapy applications. The three front-ends are: a charge-to-frequency converter developed by INFN Torino, an electrometer and a charge-to-digital converter (both commercial devices from Texas Instruments). For the first two (named DAQ A and B), the CMRP has designed the read-out systems whilst the third one (DAQ C) comes with its own evaluation board. For the purpose of the characterization DAQ A and DAQ B have been equipped …

Persona Categories: Highly Sought Places For Aussies To Live, Lachlan Hastings, Katina Michael
Associate Professor Katina Michael
The site has been touted as potentially useful to retailers trying to determine where to locate future outlets.
However, Australian Privacy Foundation vice-chair Katina Michael said companies applying profiles could get it dramatically wrong or right.
Michael said that consumers had a choice to make in light of the "big data" trend, which often mischaracterised people.
"We can continue to believe the rhetoric that says: "We are doing no harm to individuals, it is hardly tracking when profiling small neighbourhoods"... or we can begin to demand an end to the on-selling of personal information,"she said.

Researchers increasingly need to integrate the disposition, management and curation of their data into their current workflows. However, it is not yet clear to what extent faculty and students are sufficiently prepared to take on these responsibilities. This paper articulates the need for a data information literacy program (DIL) to prepare students to engage in such an “e-research” environment. Assessments of faculty interviews and student performance in a geoinformatics course provide complementary sources of information, which are then filtered through the perspective of ACRL’s information literacy competency standards to produce a draft set of outcomes for a data information literacy …
Are Low-Skill Public Sector Workers Really Overpaid? A Quasi-Differenced Panel Data Analysis, Peter Siminski
Are Low-Skill Public Sector Workers Really Overpaid? A Quasi-Differenced Panel Data Analysis, Peter Siminski
Peter Siminski
Public–private sectoral wage differentials have been studied extensively using quantile regression techniques. These typically find large public sector premiums at the bottom of the wage distribution. This may imply that low skill workers are ‘overpaid’, prompting concerns over efficiency. We note several other potential explanations for this result and explicitly test whether the premium varies with skill, using Australian data. We use a quasi-differenced Generalized Method of Moments (GMM) panel data model which has not been previously applied to this topic, internationally. Unlike other available methods, this technique identifies sectoral differences in returns to unobserved skill. It also facilitates a …

Beginning in 2011, there have been several policy changes directly affecting the management, preservation, and accessibility of publically-funded research and resulting research data in the United States. In January 18, 2011 the National Science Foundation (NSF) required data management plans to be submitted with all grant proposals. On February 22, 2013, the Office of Science and Technology Policy of the President of the United States extended a similar requirement to all federal agencies who have a research and development budget of more than $100 million. These requirements illustrate the need for further coordination and management of data as scholarship and …

In recent years there have been some significant research towards the ability of processing related data, particularly the relatedness among atomic elements in a structure with those in another structure. A number of approaches have been developed with various degrees of success. This chapter provides an overview of machine learning approaches for the encoding of related atomic elements in one structure with those in other structures. The chapter briefly reviews a number of unsupervised approaches for such data structures which can be used for solving generic classification, regression, and clustering problems. We will apply this approach to a particularly interesting …

Very High Data Rate Mb-Ofdm Uwb Systems With Transmit Diversity Techniques, Ngoc Phuc Le, Le Chung Tran, Farzad Safaei
Professor Farzad Safaei
In this paper, the application of space time block codes in a very high data rate multiband-OFDM ultra-wideband (VHDR MB-OFDM UWB) system, where the Modified Dual Carrier Modulation (MDCM) scheme and Low Density Parity Check codes are deployed, is investigated. First, we present a new table-based mapping approach and derive soft-demapping expressions for the MDCM scheme. We then propose a space-time-frequency coded VHDR MB-OFDM UWB system by incorporating space time block codes into the conventional VHDR MB-OFDM UWB system. Numerical simulations of the system supporting a data rate of 1Gbps over the IEEE 802.15.3a channel models are implemented. The simulation …

Double Space-Time Transmit Diversity For Very High Data Rate Mb-Ofdm Uwb Systems, Ngoc P. Le, Le C. Tran, Farzad Safaei
Professor Farzad Safaei
In this paper, we investigate a multiband-orthogonal frequency division multiplexing ultra-wideband (MB-OFDM UWB) system with very high data rates (VHDR) of several gigabits per second (Gbps). We propose a DSTTD-based VHDR MB-OFDM UWB system by incorporating a double space-time transmit diversity (DSTTD) scheme into the conventional MB-OFDM UWB system. At the receiver, an efficient soft-demapper that takes into consideration the noise enhancement due to a zero-forcing equalization is developed. Numerical simulations of the proposed system at a very high data rate of 2.Gbps over the IEEE 802.15.3a channel models are implemented. The simulation results show that this system could achieve …
