Strength through diversity? Learning outcomes and student satisfaction with group projects in marketing

Undergraduate students majoring in Marketing are required to engage in group projects throughout their study. The main educational rationale behind requiring students to work on group projects as an integral part of their study in marketing is that the experience of group projects is a good preparation for working in teams and managing work teams in the future. Little research has been conducted which examines the individual differences of learning outcomes with group projects. Results from a principles of marketing class (n=61) suggest that older students (>21 years) reported learning more about subject matter covered in group assignments, than younger students (<21 years). Students from non-Australian ESB and multilingual backgrounds reported gaining greater knowledge of working in teams than students from non-Australian ESB who were monolingual. Results also showed a number of interactions between age, gender and hours of work govern the degree of satisfaction students have with group learning

Time-synchronized VLF phase-tracking receiver

Coded signals transmitted at very low frequencies by National Bureau of Standards via its radio facility WWVL contain both primary time and frequency information. Synchronization of local time with WWVL signal standard requires comparison of phase differences between transmitted signal and output of traveling atomic clock such as rubidium frequency standard

A methodology to investigate and visualise the geographical provenance of road traffic casualties in deprived areas

This paper demonstrates a methodology based on spatial overlay techniques, casualty data and national deprivation scores, to quantify and visualise the geographical provenance of road traffic casualties in deprived areas. A case study of four districts with varying deprivation in Greater Manchester, UK is presented. It is shown that most injuries to pedestrians and car occupants occur in areas of similar levels of affluence/deprivation to that of where the casualties live. Thus, it is proposed that the phenomenon underlying the cause of road traffic injuries are probably universal despite the differences in factors such as demography and level of deprivation

Viscoelastic deformation near active plate boundaries

Model deformations near the active plate boundaries of Western North America using space-based geodetic measurements as constraints are discussed. The first six months of this project were spent gaining familarity with space-based measurements, accessing the Crustal Dynamics Data Information Computer, and building time independent deformation models. The initial goal was to see how well the simplest elastic models can reproduce very long base interferometry (VLBI) baseline data. From the Crustal Dynamics Data Information Service, a total of 18 VLBI baselines are available which have been surveyed on four or more occasions. These data were fed into weighted and unweighted inversions to obtain baseline closure rates. Four of the better quality lines are illustrated. The deformation model assumes that the observed baseline rates result from a combination of rigid plate tectonic motions plus a component resulting from elastic strain build up due to a failure of the plate boundary to slip at the full plate tectonic rate. The elastic deformation resulting from the locked plate boundary is meant to portray interseismic strain accumulation. During and shortly after a large interplate earthquake, these strains are largely released, and points near the fault which were previously retarded suddenly catch up to the positions predicted by rigid plate models. Researchers judge the quality of fit by the sum squares of weighted residuals, termed total variance. The observed baseline closures have a total variance of 99 (cm/y)squared. When the RM2 velocities are assumed to model the data, the total variance increases to 154 (cm/y)squared

The operational performance of hydrogen masers in the deep space network: The performance of laboratory reference frequency standards in an operational environment

Hydrogen masers used as aids in meeting the routine frequency and time operational requirements within the 64 m antenna Deep Space Network. Both the operational syntonation (frequency synchronization) and the the clock (epoch) synchronization requirements were established through the use of specifically calibrated H-P E215061A flying clock. The sync/synt to UTC was maintained using LORAN and TV in simultaneous reception mode. The sync/synt within the 64 m net was maintained through the use of very long base interferometry. Results indicate that the hydrogen masers perform well within the required specifications

Dokshitzer-Gribov-Lipatov-Altarelli-Parisi Evolution and the Renormalization Group Improved Yennie-Frautschi-Suura Theory in QCD

We show that the recently derived renormalization group improved Yennie-Frautschi-Suura (YFS) exponentiation of soft $(k_o\to 0)$ gluons in QCD is fully compatible with the usual Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) evolution of the structure functions of hadrons in the respective hadron-hadron hard interactions. We show how to implement the YFS exponentiation without double or over counting effects already implied by the DGLAP equation. In this way, we arrive at a theory which allows for the development of realistic, multiple gluon Monte Carlo event generators for hard hadron-hadron scattering processes in which the DGLAP evolved structure functions are correctly synthesized with the respective YFS exponentiated soft gluon effects in a rigorous way.Comment: 10 pages, 0 figures, 1 Latex fil
