Higher order QCD corrections to charged-lepton deep-inelastic scattering and global fits of parton distributions

We study the perturbative QCD corrections to heavy-quark structure functions of charged-lepton deep-inelastic scattering and their impact on global fits of parton distributions. We include the logarithmically enhanced terms near threshold due to soft gluon resummation in the QCD corrections at next-to-next-to-leading order. We demonstrate that this approximation is sufficient to describe the available HERA data in most parts of the kinematic region. The threshold-enhanced next-to-next-to-leading order corrections improve the agreement between predictions based on global fits of the parton distribution functions and the HERA collider data even in the small-x region.Comment: 11 pages, 6 figures, latex, extended journal versio

Get Set for Success: An update on the EngCAT project

In 2011, the Office for Learning and Teaching (OLT) funded a national project entitled "Get set for success: Using online self-assessments to motivate first year engineering students to engage in and manage their learning". This research project aims to identify factors that lead to success in first year engineering studies. The project will deliver a prototype model of the Engineering Career Appraisal Tool (EngCAT), an online educational resource that enables individuals to self-assess their cognitive (e.g., spatial, mathematical, and technical skills) and non-cognitive (e.g., personality traits, career interests and approaches to learning) abilities. Initial data have been collected and some initial results are available for the EngCAT project. Commencing engineering students across five Australian universities completed cognitive and non-cognitive tests to help them self-assess their readiness for the programs and to empower them with self-awareness and learning skills
