Making Banners and Bridges: Working Together on Global Themes

This paper is an interpretivist study of joint work between two groups of learners, one group from a Higher Education institution and the other from a small independent organisation. This collaboration provided an opening for the groups to work together from January to March in 2007 and in the same period in 2009. Before 2007, one week in the Chevening programme had been dedicated to examining community development organisations and policies in Scotland. The CD team in the Department of Adult and Continuing Education (DACE) had initially offered an annual lecture and workshop on community development and the sessions had been well received. So it was agreed in 2007 that it would be beneficial if we could include the CD students as they had much in common with the Fellows in terms of their work and studies. So both programmes were synchronised to enable the students and Fellows to work together. In 2007 the learners included the student/practitioners of the Bachelor of Community Learning and Development (BCLD) within the University of Glasgow and the Fellows of the Chevening Scholarship programme hosted and ran by the Active Learning Centre (ALC). (The BCLD was later replaced by the Bachelor of Arts in Community Development (BACD).) The joint work had gone well in 2007 so the tutors decided they would collaborate again in 2009 so the BACD student/practitioners and a different group of Fellows shared another learning experience. The University students in both the BCLD and BACD courses attended a work-based degree programme which is for people with substantial, current practice working in the community in either a paid or unpaid capacity. The Chevening programme, which has run since 2004, included ‘mid-career professionals from a variety of both Government and non-governmental organisations from all over the world’ Active Learning Centre (2003). During their time in the UK, the Fellows take part in a series of visits, lectures, workshops, roundtable discussions and placements. The collaboration had at the heart of the work some very straightforward aims which were value driven and about the benefits of mutual and reciprocal teaching and learning, supported by meaningful discussion and dialogue. The basic impetus was for the two groups of learners to come together to explore global issues from different perspectives. The groups were also given an opportunity to learn about each other’s work in civil society and governance. The aims of this partnership were simply to • to gain mutual learning • to bring the visitors into the host communities • to take the University out to relevant communities • to create sustainable relationships

A Special Purpose Architecture for Finite Element Analysis

The analysis of aerospace structures by the finite element method consumes considerable computer time. The cost of this resource and the designer's desire to have rapid feedback concerning such questions as the effect of a change in loading of the structure or in a parameter of some structural material led to the design of a special purpose parallel computing system for finite element analysis. As a special purpose computer, the architecture of this finite element computer is closely tied to computational aspects of the particular problem. Various aspects of an MIMD array of microprocessors are related to the requirements of the class of finite element analysis problems which it is intended to solve

The force on the flex: Global parallelism and portability

A parallel programming methodology, called the force, supports the construction of programs to be executed in parallel by an unspecified, but potentially large, number of processes. The methodology was originally developed on a pipelined, shared memory multiprocessor, the Denelcor HEP, and embodies the primitive operations of the force in a set of macros which expand into multiprocessor Fortran code. A small set of primitives is sufficient to write large parallel programs, and the system has been used to produce 10,000 line programs in computational fluid dynamics. The level of complexity of the force primitives is intermediate. It is high enough to mask detailed architectural differences between multiprocessors but low enough to give the user control over performance. The system is being ported to a medium scale multiprocessor, the Flex/32, which is a 20 processor system with a mixture of shared and local memory. Memory organization and the type of processor synchronization supported by the hardware on the two machines lead to some differences in efficient implementations of the force primitives, but the user interface remains the same. An initial implementation was done by retargeting the macros to Flexible Computer Corporation's ConCurrent C language. Subsequently, the macros were caused to directly produce the system calls which form the basis for ConCurrent C. The implementation of the Fortran based system is in step with Flexible Computer Corporations's implementation of a Fortran system in the parallel environment

Parallel computation with the force

A methodology, called the force, supports the construction of programs to be executed in parallel by a force of processes. The number of processes in the force is unspecified, but potentially very large. The force idea is embodied in a set of macros which produce multiproceossor FORTRAN code and has been studied on two shared memory multiprocessors of fairly different character. The method has simplified the writing of highly parallel programs within a limited class of parallel algorithms and is being extended to cover a broader class. The individual parallel constructs which comprise the force methodology are discussed. Of central concern are their semantics, implementation on different architectures and performance implications

ROSAT Observations of the Flare Star CC Eri

The flare/spotted spectroscopic binary star CC Eri was observed with the Position Sensitive Proportional Counter (PSPC) on the X-ray satellite ROSAT on 1990 July 9-11 and 1992 January 26-27. During the observations, the source was variable on time scales from a few minutes to several hours, with the X-ray (0.2-2 keV) luminosity in the range $\sim 2.5-6.8\times 10^{29} erg s^{-1}$. An X-ray flare-like event, which has a one hour characteristic rise time and a two hour decay time, was observed from CC Eri on 1990 July 10 16:14-21:34 (UT). The X-ray spectrum of the source can be described by current thermal plasma codes with two temperature components or with a continuous temperature distribution. The spectral results show that plasma at $Te\sim 10^{7}$ K exists in the corona of CC Eri. The variations in the observed source flux and spectra can be reproduced by a flare, adopting a magnetic reconnection model. Comparisons with an unheated model, late in the flare, suggest that the area and volume of the flare are substantially larger than in a solar two ribbon flare, while the electron pressure is similar. The emission measure and temperature of the non-flaring emission, interpreted as the average corona, lead to an electron pressure similar to that in a well-developed solar active region. Rotational modulation of a spot related active region requires an unphysically large X-ray flux in a concentrated area.Comment: 14 pages, compressed and uuencoded postscript file, to be published in MNRA

Biaxial constitutive equation development

In developing the constitutive equations an interdisciplinary approach is being pursued. Specifically, both metallurgical and continuum mechanics considerations are recognized in the formulation. Experiments will be utilized to both explore general qualitative features of the material behavior that needs to be modeled and to provide a means of assessing the validity of the equations being developed. The model under development explicitly recognizes crystallographic slip on the individual slip systems. This makes possible direct representation of specific slip system phenomena. The present constitutive formulation takes the anisotropic creep theory and incorporates two state variables into the model to account for the effect of prior inelastic deformation history on the current rate-dependent response of the material

The letters of Charlotte Mary Yonge (1823-1901) edited by Charlotte Mitchell, Ellen Jordan and Helen Schinske.

Charlotte Yonge is one of the most influential and important of Victorian women writers; but study of her work has been handicapped by a tendency to patronise both her and her writing, by the vast number of her publications and by a shortage of information about her professional career. Scholars have had to depend mainly on the work of her first biographer, a loyal disciple, a situation which has long been felt to be unsatisfactory. We hope that this edition of her correspondence will provide for the first time a substantial foundation of facts for the study of her fiction, her historical and educational writing and her journalism, and help to illuminate her biography and also her significance in the cultural and religious history of the Victorian age
