Data curation standards and social science occupational information resources
Occupational information resources - data about the characteristics of different occupational positions - are widely used in the social sciences, across a range of disciplines and international contexts. They are available in many formats, most often constituting small electronic files that are made freely downloadable from academic web-pages. However there are several challenges associated with how occupational information resources are distributed to, and exploited by, social researchers. In this paper we describe features of occupational information resources, and indicate the role digital curation can play in exploiting them. We report upon the strategies used in the GEODE research project (Grid Enabled Occupational Data Environment, http://www.geode.stir.ac.uk). This project attempts to develop long-term standards for the distribution of occupational information resources, by providing a standardized framework-based electronic depository for occupational information resources, and by providing a data indexing service, based on e-Science middleware, which collates occupational information resources and makes them readily accessible to non-specialist social scientists
Data curation standards and the messy world of social science occupational information resources
Occupational information resources – data about the characteristics of different occupational positions – play a unique role in social science research. They are of relevance across diverse research disciplines and in numerous disparate contexts. They are also very widely available, typically freely downloadable from research-oriented academic web-pages. But they are also one of the most uncoordinated types of information resource that social scientists routinely come across. In this paper we describe issues in curating occupational information resources during the GEODE research project (Grid Enabled Occupational Data Environment, http:/www.geode.stir.ac.uk). This project attempts to develop long-term standards for the distribution of occupational information resources, by providing a standardised framework electronic depository for occupational information resources, and by providing a data-indexing service, premised upon eScience middleware, which collates occupational information resources and makes them readily accessible to non-specialist social scientists
Analytic Expression for the Joint x and Q^2 Dependences of the Structure Functions of Deep Inelastic Scattering
We obtain a good analytic fit to the joint Bjorken-x and Q^2 dependences of
ZEUS data on the deep inelastic structure function F_2(x, Q^2). At fixed
virtuality Q^2, as we showed previously, our expression is an expansion in
powers of log (1/x) that satisfies the Froissart bound. Here we show that for
each x, the Q^2 dependence of the data is well described by an expansion in
powers of log Q^2. The resulting analytic expression allows us to predict the
logarithmic derivatives {({\partial}^n F_2^p/{{(\partial\ln Q^2}})^n)}_x for n
= 1,2 and to compare the results successfully with other data. We extrapolate
the proton structure function F_2^p(x,Q^2) to the very large Q^2 and the very
small x regions that are inaccessible to present day experiments and contrast
our expectations with those of conventional global fits of parton distribution
functions.Comment: 4 pages, 3 figures, a few changes in the text. Version to be

Ultra-high energy neutrino scattering
Estimates are made of the ultra-high energy neutrino cross sections based on
an extrapolation to very small Bjorken x of the logarithmic Froissart
dependence in x shown previously to provide an excellent fit to the measured
proton structure function F_2^p(x,Q^2) over a broad range of the virtuality
Q^2. Expressions are obtained for both the neutral current and the charged
current cross sections. Comparison with an extrapolation based on perturbative
QCD shows good agreement for energies where both fit data, but our rates are as
much as a factor of 10 smaller for neutrino energies above 10^9 GeV, with
important implications for experiments searching for extra-galactic neutrinos.Comment: 4 pages, 1 figure, 1 table; Title, abstract and text changed,

ATLAS Commander: an ATLAS production tool
This paper describes the ATLAS production tool AtCom (for ATLAS Commander).
The purpose of the tool is to automate as much as possible the task of a
production manager: defining and submitting jobs in large quantities, following
up upon their execution, scanning log files for known and unknown errors,
updating the various ATLAS bookkeeping databases on successful completion of a
job whilst cleaning up and resubmitting otherwise. The design of AtCom is
modular, separating the generic basic job management functionality from the
interactions with the various databases on the one hand, and the computing
systems on the other hand. Given the near future reality of different flavors
of computing systems (legacy and GRID) deployed concurrently at the various, or
even a single ATLAS site, AtCom allows several of them to be used at the same
time transparently.Comment: Talk from the 2003 Computing in High Energy and Nuclear Physics

Small x Behavior of Parton Distributions from the Observed Froissart Energy Dependence of the Deep Inelastic Scattering Cross Section
We fit the reduced cross section for deep-inelastic electron scattering data
to a three parameter ln^2 s fit, A + beta ln^2 (s/s_0), where s= [Q^2/x] (1-x)
+ m^2, and Q^2 is the virtuality of the exchanged photon. Over a wide range in
Q^2 (0.11 < Q^2 < 1200 GeV^2) all of the fits satisfy the logarithmic energy
dependence of the Froissart bound. We can use these results to extrapolate to
very large energies and hence to very small values of Bjorken x -- well beyond
the range accessible experimentally. As Q^2 --> infinity, the structure
function F_2^p(x, Q^2) exhibits Bjorken scaling, within experimental errors. We
obtain new constraints on the behavior of quark and antiquark distribution
functions at small x.Comment: 10 pages, 2 figure
Extension of the Wu-Jing equation of state (EOS) for highly porous materials: thermoelectron based theoretical model
A thermodynamic equation of state (EOS) for thermoelectrons is derived which
is appropriate for investigating the thermodynamic variations along isobaric
paths. By using this EOS and the Wu-Jing (W-J) model, an extended Hugoniot EOS
model is developed which can predict the compression behavior of highly porous
materials. Theoretical relationships for the shock temperature, bulk sound
velocity, and the isentrope are developed. This method has the advantage of
being able to model the behavior of porous metals over the full range of
applicability of pressure and porosity, whereas methods proposed in the past
have been limited in their applicability.Comment: 18 pages, 1 figure, appeared at J. Appl. Phys. 92, 5924 (2002
An Exploratory Study of Extended Health Care Practitioner Roles in Medication Supply and Management in a Rural Community
Australia has a recognised shortage of qualified health professionals, particularly in rural and regional areas. Research has shown that rural patients indeed have poorer health status compared to metropolitan communities, with rates of mortality and morbidity constantly higher in rural regions.
A number of ‘novel’ and ‘extended’ roles have been developed for existing health care professionals. Some of these roles have application to rural areas, such as additional functions in terms of provision of medicines. In Queensland in particular, the Health (Drugs and Poisons) Regulation 1996 (the Regulation), which provides the regulatory framework for the handling of medicines, has been amended to include a range of endorsements, including Indigenous Health Workers (IHW) and Rural and Isolated Practice-endorsed Nurses (RIPRN). Another development is the amendment of the Regulation to allow for a range of health professionals, namely optometrists, physicians’ assistants and nurse practitioners, to prescribe medicines. Whether such developments have addressed the needs of rural communities remains unknown.
Inherently, rural communities will suffer from limited access to health care services, and the services of the existing health care providers may be stretched to, or beyond, the scope of their recognised practice in order to meet the needs of the community. Little is known about the extent and nature of these ‘extended’ practices, the perceived need for (or obligation on) health professionals to adopt these roles, and the ethical, professional and legal considerations if/when they extend their services into non-traditional territories.
This research specifically focussed on the involvement of various health care providers in patients’ medication management in a defined community or region. In doing so, it aimed to identify medication-related issues of a community and the potential roles for pharmacists to enhance safe, effective and efficient access to medicines in a rural setting.Griffith Health, School of PharmacyFull Tex
