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.

Determining Data Information Literacy Needs: A Study Of Students And Research Faculty, Jake R. Carlson, Michael Fosmire, Chris Miller, Megan R. Sapp Nelson

Michael Fosmire

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 …

Sample Design Using Imperfect Design Data, Robert Clark

Robert Clark

A well-designed sampling plan can greatly enhance the information that can be produced from a survey. Once a broad sample design is identified, specific design parameters such as sample sizes and selection probabilities need to be chosen. This is typically achieved using an optimal sample design, which minimizes the variance of a key statistic or statistics, expressed as a function of design parameters and population characteristics, subject to a cost constraint. In practice, only imprecise estimates of population characteristics are available, but the effects of this variability are usually ignored. A general approach to sample allocation allowing for imprecise design …

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 …

Opportunities And Challenges Of Data Publication: A Case Study From Purdue, David Scherer, Lisa Zilinski, Courtney E. Matthews

Lisa Zilinski

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 …

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

Qingsheng Zhang

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 …

Labor Market Data Needs Relating To Antidiscrimination Activity: Comment, Ronald Ehrenberg

Ronald G. Ehrenberg

[Excerpt] Barbara Bergmann's background paper divides data needs in the antidiscrimination area into data that would be useful in the formulation of national policy and data that would be useful as an aid in enforcing the laws and executive orders against discrimination. Although the former are likely to be of greatest concern to the commission, she has performed a valuable service by discussing these interrelated needs in one place. I find much to agree with, and very little to disagree with or question, in her paper. The presentation is, in the main, an objective one and she tempers her desire …

Data Driven Encoding Of Structures And Link Predictions In Large Xml Document Collections, M Hagenbuchner, A C. Tsoi, M Kc, Shujia Zhang

Ah Chung Tsoi

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 …

Learning To Live Without A Statistical Abstract: Thinking About Future Access To Government Information, James Shaw

James B Shaw

Twenty-four years ago, in 1987, I made a presentation called “Basic Ready Reference: Documents that a Reference Librarian Cannot Live Without” at a meeting of the Iowa Library Association Government Documents Round Table. My top recommendation was the Statistical Abstract of the United States, that annual compendium of data so familiar and indispensible to American librarians everywhere. Twelve years ago, in 1999, I made a similar presentation at the NLA/NEMA Annual Conference, and again the Statistical Abstract took its place as the preeminent resource. The title of my presentation today, “Learning to Live Without a Statistical Abstract,” signals that our …

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 …

Ignoring A Level In A Multilevel Model: Evidence From Uk Census Data, Mark Tramner, David Steel

Professor David Steel

Because of the inherent multilevel nature of census data, it is often appropriate to use multilevel models to investigate relationships between census variables. For a local population, the data available from the census allow a three-level nested model to be assumed, with an individual level (level 1), an enumeration district (ED) level (level 2), and a ward level (level 3). The consequences of ignoring one of the three levels in this model are assessed here theoretically. Empirical results, based on 1991 UK Census data, are also provided, comparing the variance components estimated from the three-level model with analyses based on …

Restricted Quasi-Score Estimating Functions For Sample Survey Data, Yan Lin, David Steel, Raymond Chambers

Professor David Steel

This paper applies the theory of the quasi-likelihood method to model-based inference for sample surveys. Currently, much of the theory related to sample surveys is based on the theory of maximum likelihood. The maximum likelihood approach is available only when the full probability structure of the survey data is known. However, this knowledge is rarely available in practice. Based on central limit theory, statisticians are often willing to accept the assumption that data have, say, a normal probability structure. However, such an assumption may not be reasonable in many situations in which sample surveys are used. We establish a framework …

The Information In Aggregate Data, David Steel, Eric Beh, Raymond Chambers

Professor David Steel

Ecological inference attempts to draw conclusions concerning individual-level relationships using data in the form of aggregates for groups in the population. The groups are often geographically defined. A fundamental statistical issue is how much information aggregate data contain concerning the relationships and parameters that we are trying to estimate. The information affects the standard errors of estimates as well as the power of any tests of hypothesis. It also affects the ability to tell, from the aggregate data, which different models under consideration are supported by the data. In this chapter likelihood-based methods are considered. We show in general how …

Yes, But What Is It That You Do?, Amanda Rinehart

Amanda Rinehart

Despite carefully crafted job descriptions, e-science or data librarians find that there is little consensus on position responsibilities and required competencies. Consequently, these librarians tend to customize their positions around what their clientele require. Indeed, data “Curation Service Models [are] driven by user requirements”. Therefore, it’s not just about the data – it’s about the people. Specifically, it’s about the different cultures of user groups and librarians and how to communicate effectively across these groups. The “elevator speech” for a scientist might be quite different from the one for your librarian colleague. It’s no wonder that a recent survey of …

Updating The Dietadvice Website With New Australian Food Composition Data, Yasmine Probst, Holley-Anne Jones, Shannon Lin, S. Burden, David G. Steel, Linda C. Tapsell

Professor David Steel

DietAdvice is an Australian self-administered dietary assessment website initially developed in 2003- 2005. The website allows patients to enter their dietary information and dieticians to remotely access and interpret the data. DietAdvice is presently being updated with new Australian food composition data. This study aims to describe the update process for moving from 1995 to 2006 food composition data. The database for the website was developed using grouped food data from the NUTTAB 1995 database. All food groups were cross-matched with the food from the NUTTAB 2006 database using the food ID codes. Rules were applied to determine the suitability …

Dissecting The Workforce And Workplace For Clinical Endocrinology, And The Work Of Endocrinologists Early In Their Careers, Claude Desjardins, Mark A. Bach, Anne R. Cappola, Ellen W. Seely, Ronald G. Ehrenberg

Ronald G. Ehrenberg

[Excerpt] No national mechanism is in place for an informed, penetrating, and systematic assessment of the physician workforce such as that achieved by the National Science Foundation (NSF) for the periodic evaluation of the nation’s scientists and engineers. Likewise, knowledge of the workforce for clinical research is enigmatic and fragmentary despite the serial recommendations of “blue-ribbon” panels to establish a protocol for the recurrent assessment of clinical investigators early in their careers. Failure to adopt a national system for producing timely, high-quality data on the professional activities of physicians limits the application of improvement tools for advancing clinical investigation and …
