Determination of Priorities for Footway Reconstruction
This report describes a study conducted for Sheffield City
Council to obtain pedestriansr reactions to the quality and
acceptability of footways of different construction in
different conditions, and to assess pedestriansr preferences
for different types of footway construction. The results are
intended to aid the Council in identifying priorities for the
maintenance of existing footways, and preferred surfaces for
new or reconstructed footways. The study involved four
stages; a new survey to identify footway characteristics of
concern to pedestrians; interviews and objective measurements
at a total of 13 sites; interviews at a set of eight purpose
built trial sites; and analysis and interpretation of the
results
Ergonomic Standards for Disabled People in Pedestrian Areas : Results from Leeds Observation Work 1988/89
This working paper is one of a series (WP 252, 253, 254, 255, 274, 275), describing work undertaken under contract to TRRL investigating design guidance for pedestrian areas and footways to satisfy the needs of disabled and elderly people. This working paper reports on fieldwork conducted with disabled people in Leeds to investigate movement distances; assessments of surface conditions including gaps, undulation, gradients, camber and friction; and assessments of bus shelter seating

Economic Standards for Pedestrian Areas for Disabled People: Results from Observation Work
1.1.1 The Institute for Transport Studies was invited by the
Transport and Road Research Laboratory to submit a research
proposal, with costs, aimed at establishing suitable "Ergonomic
Standards for Pedestrian Areas for Disabled People". The project
commenced on 1st July, 1986 and was split into two parts, with
part one involving four months' work over the period to 31st
December, 1986 and part two finishing on 30th April, 1988.
1.1.2
The -objectives of the study laid down in the design
brief by the Transport and Road Research Laboratory were:
a) To produce a guide to good practice for the design and
maintenance of footways and pedestrianised areas;
b) To provide, where possible, recommended standards for design
and maintenance.
The good practice guide and the recommended standards were to be
primarily aimed at disabled people and the elderly, but the
requirements of the able-bodied were also to be considered, as
were conflicts between the needs of different groups of user.
The economic implications of implementation and maintenance were
also to be detailed.

Developing a competence framework for cognitive analytic therapy
Objective
This paper describes the development and summarizes the content of a competence framework for delivery of cognitive analytic therapy (CAT).
Design
The framework was developed using the evidence‐based method developed by Roth and Pilling (2008, Behavioural and Cognitive Psychotherapy, 36, 129).
Methods
A review of the CAT outcome literature identified where CAT interventions had evidence of efficacy. Standard texts on CAT were primary sources for details of theory and practice. This process was supported by an expert reference group (ERG). The role of the ERG was to provide professional advice on areas where the evidence base was lacking, but where CAT interventions were commonly used by therapists trained in the model.
Results
A framework was produced and structured in terms of core knowledge, core skills, and meta‐competences (which require therapeutic judgement rather than simple adherence to a treatment protocol).
Conclusions
The framework enables trainees, service users, service managers, and commissioners to better understand a) the core features of CAT and b) what competences need to be in place for CAT to be skilfully delivered in practice.
Practitioner points
It is possible to define the core competences of CAT.
Whilst generic competences are important, there are five CAT‐specific domains of competence.
The CAT‐specific competences reflect the three‐phase structure of the therapy: reformulation, recognition, and revision
A role for glycosaminoglycans in the development of collagen fibrils
AbstractExtensive data on the glycosaminoglycan (GAG) composition and the collagen fibril diameter distribution have been collected for a diverse range of connective tissues. It is shown that tissues with the smallest diameter collagen fibrils (mass-average diameter < 60 nm) have high concentrations of hyaluronic acid and that tissues with the largest diameter collagen fibrils (mass-average diameter ∼200 nm) have high concentrations of dermatan sulphate. It is suggested that the lateral growth of fibrils beyond a diameter of about 60 nm is inhibited by the presence of an excess of hyaluronic acid but that this inhibitory effect may be removed by an increasing concentration of chondroitin sulphate and/or dermatan sulphate. It is also postulated that high concentrations of chondroitin sulphate will inhibit fibril growth beyond a mass-average diameter of ∼150 nm. Such an inhibition may in turn be removed by an increasing concentration of dermatan sulphate such that it becomes the dominant GAG present in the tissue
Gauged Inflation
We propose a model for cosmic inflation which is based on an effective
description of strongly interacting, nonsupersymmetric matter within the
framework of dynamical Abelian projection and centerization. The underlying
gauge symmetry is assumed to be with . Appealing to a
thermodynamical treatment, the ground-state structure of the model is
classically determined by a potential for the inflaton field (dynamical
monopole condensate) which allows for nontrivially BPS saturated and thereby
stable solutions. For this leads to decoupling of gravity from the
inflaton dynamics. The ground state dynamics implies a heat capacity for the
vacuum leading to inflation for temperatures comparable to the mass scale
of the potential. The dynamics has an attractor property. In contrast to the
usual slow-roll paradigm we have during inflation. As a consequence,
density perturbations generated from the inflaton are irrelevant for the
formation of large-scale structure, and the model has to be supplemented with
an inflaton independent mechanism for the generation of spatial curvature
perturbations. Within a small fraction of the Hubble time inflation is
terminated by a transition of the theory to its center symmetric phase. The
spontaneously broken symmetry stabilizes relic vector bosons in the
epochs following inflation. These heavy relics contribute to the cold dark
matter of the universe and potentially originate the UHECRs beyond the GZK
bound.Comment: 23 pages, 4 figures, subsection added, revision of text, to app. in
