A study of the usefulness of Skylab EREP data for earth resources studies in Australia

The author has identified the following significant results. Preliminary results show that the high resolution imagery has, potentially, an operational role in geological surveying and the design of major engineering works, and is much more promising in this regard than the low resolution Skylab and ERTS-1 imagery

Core content modules at Leeds Metropolitan University

As part of Leeds Metropolitan University’s review of the postgraduate curriculum in 2012–13, Libraries and Learning Innovation (LLI) was asked to lead a project group to create two core content modules for use at Level 7 (Masters level) in Research Practice and Project Management. The rationale for choosing these two areas was the sheer number of modules in these subjects taught across a wide range of disciplines, each of which is currently designed and populated by individual course teams. The group consisted of representatives from the University’s Centre for Teaching and Learning, academic staff, learning technologists and academic librarians, and was chaired by the Associate Director of LLI, Wendy Luker

Recovery of the Shape of the Mass Power Spectrum from the Lyman-alpha Forest

We propose a method for recovering the shape of the mass power spectrum on large scales from the transmission fluctuations of the Lyman-alpha forest, which takes into account directly redshift-space distortions. The procedure, in discretized form, involves the inversion of a triangular matrix which projects the mass power spectrum in 3-D real-space to the transmission power spectrum in 1-D redshift-space. We illustrate the method by performing a linear calculation relating the two. A method that does not take into account redshift-space anisotropy tends to underestimate the steepness of the mass power spectrum, in the case of linear distortions. The issue of the effective bias-factor for the linear distortion kernel is discussed.Comment: 18 pages, 4 figures; minor revision

Fluctuating loops and glassy dynamics of a pinned line in two dimensions

We represent the slow, glassy equilibrium dynamics of a line in a two-dimensional random potential landscape as driven by an array of asymptotically independent two-state systems, or loops, fluctuating on all length scales. The assumption of independence enables a fairly complete analytic description. We obtain good agreement with Monte Carlo simulations when the free energy barriers separating the two sides of a loop of size L are drawn from a distribution whose width and mean scale as L^(1/3), in agreement with recent results for scaling of such barriers.Comment: 11 pages, 4 Postscript figure

The impact of expanding advanced level secondary school students' awareness and use of metacognitive learning strategies on confidence and proficiency in foreign language speaking skills

In an increasingly multilingual world, the question of how to improve foreign language speaking skills of pupils in British schools is of paramount importance to language teachers and policy makers today. This paper examines how an explicit focus on metacognitive strategy use within secondary school foreign language lessons impacts pupils' confidence and proficiency in speaking. The small-scale action research study was conducted with a class of five Year Twelve (age 16-17) Advanced Level learners of French in a secondary school in England. While all of the pupils generally achieved well in the reading, writing and listening aspects of the course, they performed considerably less well in speaking tasks. The primary aim of this study was therefore to introduce the students to a range of metacognitive learning strategies with a view to improving their confidence and proficiency in speaking. Data was collected from questionnaires, interviews, strategy checklists and assessment marks collected both before and after a six-week period of strategy instruction. The findings indicate that the use of learning strategies seems to have had a positive impact on pupils' confidence and proficiency in speaking and after the intervention the participants reported an increase in how much they both valued and used a range of metacognitive strategies.This is the accepted manuscript.

Flight investigation of the VFR and IFR landing approach characteristics and terminal area airspace requirements for a light STOL airplane

A flight research program was conducted to determine the terminal area instrument flight capabilities of a light STOL airplane. Simulated (hooded) instrument landing approaches were made using steep single-segment and two-segment glide slopes. A brief investigation was also made of the visual flight terminal area capabilities of the aircraft. The results indicated that the airplane could be flown on a 7 deg glide-slope ILS-type approach in still air with an adequate 3 deg margin for downward correction

Compound nuclear decay and the liquid to vapor phase transition: a physical picture

Analyses of multifragmentation in terms of the Fisher droplet model (FDM) and the associated construction of a nuclear phase diagram bring forth the problem of the actual existence of the nuclear vapor phase and the meaning of its associated pressure. We present here a physical picture of fragment production from excited nuclei that solves this problem and establishes the relationship between the FDM and the standard compound nucleus decay rate for rare particles emitted in first-chance decay. The compound thermal emission picture is formally equivalent to a FDM-like equilibrium description and avoids the problem of the vapor while also explaining the observation of Boltzmann-like distribution of emission times. In this picture a simple Fermi gas thermometric relation is naturally justified and verified in the fragment yields and time scales. Low energy compound nucleus fragment yields scale according to the FDM and lead to an estimate of the infinite symmetric nuclear matter critical temperature between 18 and 27 MeV depending on the choice of the surface energy coefficient of nuclear matter.Comment: Five page two column pages, four figures, submitted to Phys.

Pulsed versus DC I-V characteristics of resistive manganites

We report on pulsed and DC I-V characteristics of polycrystalline samples of three charge-ordered manganites, Pr_{2/3}Ca_{1/3}MnO_3, Pr_{1/2}Ca_{1/2}MnO_3, Bi_{1/2}Sr_{1/2}MnO_3 and of a double-perovskite Sr_2MnReO_6, in a temperature range where their ohmic resistivity obeys the Efros-Shklovskii variable range hopping relation. For all samples, the DC I(V) exhibits at high currents negative differential resistance and hysteresis, which mask a perfectly ohmic or a moderately nonohmic conductivity obtained by pulsed measurements. This demonstrates that the widely used DC I-V measurements are usually misleading.Comment: 6 pages, 4 figures. Accepted for publication to AP

Strategy development and cross-linguistic transfer in foreign and first language writing

Abstract In an increasingly multilingual world, empirical knowledge about the reciprocal influence between the mother tongue (L1) and a learner’s acquisition of foreign languages (FL) is crucial yet remains surprisingly scarce. This paper examines how an explicit focus on metacognitive strategy use within a FL (German) classroom impacts students’ development of writing strategies in the FL, and whether any such effects transfer to another FL (French) and/or to the L1 (English). Based on a quasi-experimental design, the study involved a two-phase intervention of strategy-based instruction primarily in the FL classroom and later also in the English classroom in a secondary school in England. Data were collected using writing strategy task sheets. Key findings indicate high levels of cross-linguistic transfer, both from one FL context to another and from FL – L1, evidenced especially by an improvement in the quality of students’ planning and a reduction in the number of errors. Findings support the development of a multilingual, strategy-based pedagogy for writing where L1 and FL teachers collaborate to encourage and facilitate connection-making across language contexts.</jats:p
