Assessment of Self-Archiving in Institutional Repositories: Depositorship and Full-Text Availability
No full textThis research evaluates the success of open access self-archiving in several well-known institutional repositories. Two assessment factors have been applied to examine the current practice of self-archiving: depositorship and the availability of full text. This research discovers that the rate of author self-archiving is low and that the majority of documents have been deposited by a librarian or administrative staff. Similarly, the rate of full-text availability is relatively low, except for Australian repositories. By identifying different practices of self-archiving, repository managers can create new strategies for the operation of their repositories and the development of archiving policies
Factors to Assess Self-Archiving in Institutional Repositories
No full textThis paper proposes a group of factors that may be used to assess the success of open access self-archiving. It concentrates on self-archiving in institutional repositories. The authors emphasize the importance of examining content materials, particularly the availability of full text versus abstracts and the deposits archived by authors versus by others.Peer reviewe

Competences and responsibilities of social science data librarians: an analysis of job descriptions
No full textThis study examines job announcements for social science data librarians and professionals to identify trends in the profession. A collection of 167 job postings in 2005–2012 from the International Association for Social Science Information Services &Technology website was analyzed on the frequencies of term occurrence and co-occurrence in job qualifications and responsibilities. The study verifies that employers valued non-technical skills as heavily as technical skills, and detects dissimilar emphases of data activities for data librarians and non-librarian professionals: the former on data discovery and collection, and the latter on data analysis and preservation. An increasing requirement of data management planning was also found for data librarians.Peer reviewe
Ultra-sensitive carbon based molecular sensors
No full textThis thesis presented the study of carbon-based materials for ultra-sensitive molecular sensing.
Reduced Graphene Oxide (rGO), a 2-dimensional one-atomic layer thick carbon material, had the advantage of low-cost, aqueous and industrial-scalable production route. Using rGO as the transducer platform could potentially lower the cost of sensors down to a few dollars per chip. However, there were still limitations in rGO that prevented its widespread usage as a biosensor transducer or in electronics: its low electrical conductivity and large electrical deviations. This thesis was structured to understand and solve these problems for transducer application. The thesis could be broken down into 3 parts:
The first part of the thesis presented the critical review of the background and limitations of graphene research, followed by the background and importance of biosensor developments for the detection of sweat sodium ions and circulatory Interleukin-6 proteins.
The second part of the thesis tested the hypothesis that the rGO limitations could be eliminated to create a highly sensitive biosensor transducer via (A) improving rGO synthesis (B) pristine Carbon Nanotubes-rGO hybrid film and (C) growth of rGO. The mechanism of ultra-large graphene oxide synthesis and graphene oxide growth was also elucidated in this section.
The third part of the thesis then presented the fabrication and test of the practical and homogenous carbon-based biosensor using the transducer synthesized earlier. The thesis showed that through proving the hypothesis correct, it enabled the synthesis of an all organic sodium ion sensor with integrated pump and an ultra-sensitive interleukin-6 bio-sensor. Both of these novel sensors were able to detect the respective molecules in their physiological ranges

Personal name identification in the practices of digital repositories
No full textThis paper finds that the variations of authors' names have negatively affected the retrieval capability of digital repositories. Two possible solutions include using composite identifiers that combine author name, publication date, and author affiliation, and also asking authors to input the variants of their name, if any, at the time of depositing articles

No full textTwo-dimensional jets in a weak crossflow
No full textThe behaviours of a two-dimensional and line jets in a weak cross-flow are studied in the laboratory and through the development of analytical and numerical models.Laser Induced Fluorescence (LIF) and Image Processing (IP) techniques are employed to visualize the flow and provide quantitative information about the jet behaviour. This information includes data for the mean properties, such as jet dilution, spread and trajectory, and turbulent properties, such as Root-Mean-Square (RMS) of tracer concentration fluctuation and intermittency (ITY) of concentration distribution.Predictive models are developed for 2D weakly-advected jets, where it is assumed that the flow behaviour is similar to that of a jet in a still ambient fluid. Both numerical and analytical solutions are obtained. Analytical solutions require the control volume surfaces through which the jet flows to be perpendicular to the direction of the initial discharge. The numerical solution allows a control volume that is perpendicular to the excess velocity profile and it therefore rotates as the discharge is deflected. Comparisons of these two models show that in the weakly-advected region the solutions are very similar and the relatively simple analytical solution is adequate.Comparisons between the experimental data and model predictions show that the transition from weakly-advected region to strongly-advected region happens when z/Zws=0.4. In weakly-advected region, the spread of the weakly-advected jet is significantly larger than that of a jet in a still ambient fluid. Although there appears to be a weak dependence on the strength of the ambient current, a significant increase in spread rate is evident at initial velocity ratios (ambient to discharge) as low as 0.0117. Beyond z/Zws=0.4, dilution rate increases rapidly and model predictions are no longer valid. These comparisons also show that in order to predict the location of the jet it is necessary to incorporate the impact of pressure variations across the jet. Hence, A drag term is incorporated into the model for this purpose. For a two-dimensional jet in a week cross-flow, the drag coefficient CD has a value of 0.8.The experiments also enable comparisons to be made between the behaviour of line jets and two-dimensional jets. These comparisons show the ambient current dominates the line jet behaviour much closer to the source, when compared to an equivalent two-dimensional jet in a cross-flow.</p
