Image retrieval by hypertext links
This paper presents a model for retrieval of images from a large World Wide Web based collection. Rather than considering complex visual recognition algorithms, the model presented is based on combining evidence of the text content and hypertext structure of the Web. The paper shows that certain types of query are amply served by this form of representation. It also presents a novel means of gathering relevance judgements
Demonstration of lightweight gamma spectrometry systems in urban environments
Urban areas present highly complex radiation environments; with small scale features resulting from different construction materials, topographic effects and potential anthropogenic inputs from past industrial activity or other sources. Mapping of the radiation fields in urban areas allows a detailed assessment of exposure pathways for the people who live and work there, as well as locating discrete sources of activity that may warrant removal to mitigate dose to the general public. These areas also present access difficulties for radiometric mapping using vehicles or aircraft. A lightweight portable gamma spectrometry system has been used to survey sites in the vicinity of Glasgow to demonstrate the possibilities of radiometric mapping of urban areas, and to investigate the complex radiometric features such areas present. Variations in natural activity due to construction materials have been described, the presence of 137Cs used to identify relatively undisturbed ground, and a previously unknown NORM feature identified. The effect of topographic enclosure on measurements of activity concentration has been quantified. The portable system is compared with the outputs that might be expected from larger vehicular or airborne systems. For large areas airborne surveys are the most cost effective approach, but provide limited spatial resolution, vehicular surveys can provide sparse exploratory data rapidly or detailed mapping of open areas where off-road access is possible. Backpack systems are ideally suited to detailed surveys of small areas, especially where vehicular access is difficult
Social Enterprise Education for Health Care Professionals
Stimulated by policy documents at the beginning of this millenium such as ‘A Health Service for all of the Talents’ (DOH 2000a), ‘The NHS Plan’ (DOH 2000b), ‘Working Together-Learning Together’ (DOH 2001a), and ‘Benchmarking Academic and Practitioner Standards’ (Quality Assurance Agency 2001), The Faculty of Health here at Leeds Met established, in 2006, a pre-registration Interprofessional Learning Programme (ILP) with the aim of enhancing interprofessional working practices within service delivery. This ILP is summatively assessed and embedded in a module in each student’s own professional course.
More recently there has been increasing recognition by the NHS that many aspects of health care provision, particularly reaching groups that do not effectively access existing health care services, can best be met by social enterprises with the aim of reducing health inequalities.
There are currently more than 6,000 social enterprises delivering health and social care within the NHS (State of Social Enterprise Survey, 2009, Social Enterprise Coalition). his number is set to rise considerably with the introduction in 2008 of the NHS Right to Request initiative which provides funding and support for health Care professionals who have the vision and drive to develop, through Social Entereprises (SE’s), better service delivery within health and social care. Consequently there is an need within the present ILP to develop both an awareness of the role of SE’s in service provision and intrapreneurial and enterprise skills.
Embedding enterprise education within the ILP will also enhance employability prospects for those of our graduates who in the present economic climate can no longer assume they will achieve employment within the NHS or those who already have aspirations to develop their own business practice – perhaps in partnership with practitioners from other disciplines.
In addition the Faculty portfolio of courses now includes degrees in Complementary Therapies such as Osteopathy, Acupuncture and Herbal Medicine. Graduates in these disciplines participate in the ILP but traditionally establish their own business practices
Spatial information retrieval and geographical ontologies: an overview of the SPIRIT project
A large proportion of the resources available on the world-wide
web refer to information that may be regarded as geographically
located. Thus most activities and enterprises take place in one or
more places on the Earth's surface and there is a wealth of survey
data, images, maps and reports that relate to specific places or
regions. Despite the prevalence of geographical context, existing
web search facilities are poorly adapted to help people find
information that relates to a particular location. When the name of
a place is typed into a typical search engine, web pages that
include that name in their text will be retrieved, but it is likely
that many resources that are also associated with the place may
not be retrieved. Thus resources relating to places that are inside
the specified place may not be found, nor may be places that are
nearby or that are equivalent but referred to by another name.
Specification of geographical context frequently requires the use
of spatial relationships concerning distance or containment for
example, yet such terminology cannot be understood by existing
search engines. Here we provide a brief survey of existing
facilities for geographical information retrieval on the web, before
describing a set of tools and techniques that are being developed
in the project SPIRIT : Spatially-Aware Information Retrieval on
the Internet (funded by European Commission Framework V
Project IST-2001-35047)
The impact of private sector provision on equitable provision of coronary revascularisation
Objective: To investigate the impact of including private sector data on assessments of equity of coronary revascularisation provision using NHS data only.
Design: Analyses of Hospital Episodes Statistics and private sector data by age, sex, and PCT of residence. For each PCT, the share of London's total population and revascularisations (all admissions, NHS-funded, and privately-funded admissions) were calculated. GINI coefficients were derived to provide an index of inequality across sub-populations, with parametric bootstrapping to estimate confidence intervals.
Setting: London Participants London residents undergoing coronary revascularisation April 2001 - December 2003. Intervention Coronary artery bypass graft or angioplasty
Main outcome measures: Directly-standardised revascularisation rates, GINI coefficients.
Results: NHS-funded age-standardised revascularisation rates varied from 95.2 to 193.9 per 100,000 and privately funded procedures from 7.6 to 57.6. Although the age distribution did not vary by funding, the proportion of revascularisations among women that were privately funded (11.0%) was lower than among men (17.0%). Privately funded rates were highest in PCTs with the lowest death rates (p=0.053). NHS-funded admission rates were not related to deprivation nor age-standardised deaths rates from coronary heart disease. Privately-funded admission rates were lower in more deprived PCTs. NHS provision was significantly more egalitarian (Gini coefficient 0.12) than the private sector (0.35). Including all procedures was significantly less equal (0.13) than NHS funded care alone.
Conclusion: Private provision exacerbates geographical inequalities. Those responsible for commissioning care for defined populations must have access to consistent data on provision of treatment wherever it takes place
Task planning and control synthesis for robotic manipulation in space applications
Space-based robotic systems for diagnosis, repair and assembly of systems will require new techniques of planning and manipulation to accomplish these complex tasks. Results of work in assembly task representation, discrete task planning, and control synthesis which provide a design environment for flexible assembly systems in manufacturing applications, and which extend to planning of manipulatiuon operations in unstructured environments are summarized. Assembly planning is carried out using the AND/OR graph representation which encompasses all possible partial orders of operations and may be used to plan assembly sequences. Discrete task planning uses the configuration map which facilitates search over a space of discrete operations parameters in sequential operations in order to achieve required goals in the space of bounded configuration sets
Meeting of the MINDS: an information retrieval research agenda
Since its inception in the late 1950s, the field of Information Retrieval (IR) has developed tools that help people find, organize, and analyze information. The key early influences on the field are well-known. Among them are H. P. Luhn's pioneering work, the development of the vector space retrieval model by Salton and his students, Cleverdon's development of the Cranfield experimental methodology, Spärck Jones' development of idf, and a series of probabilistic retrieval models by Robertson and Croft. Until the development of the WorldWideWeb (Web), IR was of greatest interest to professional information analysts such as librarians, intelligence analysts, the legal community, and the pharmaceutical industry

Determinants of satisfaction amongst tenants of UK Offices
Purpose – Corporate Occupiers require offices and services which meet their business needs, whilst
landlords must attract and retain occupiers in order to maximise occupancy and rental income. The purpose
of this research is to help landlords and corporate occupiers understand each other better, in order to achieve a mutually beneficial relationship.
Design/methodology/approach - This paper analyses interviews with 1334 office tenants in the UK,
conducted over an 11-year period, to investigate determinants of occupier satisfaction, loyalty and advocacy. Structural equation modelling and regressions are performed using respondents’ ratings of satisfaction with many aspects of occupancy as explanatory variables. The dependent variables include satisfaction with
property management, value for money, overall occupier satisfaction, lease renewal intentions and occupiers’
willingness to recommend their landlord.
Findings - The aspects with most impact on occupiers’ satisfaction are the office building itself, its location
and amenities, and also communication with their property manager, a belief that their business needs are
understood and the property manager’s responsiveness to occupiers’ requests. Occupiers’ loyalty depends
mainly upon feeling that their rent and service charges provide value for money, an amicable leasing
process, the professionalism of their property manager and the Corporate Social Responsibility of the
Landlord. ‘Empathy’ is crucial to occupiers’ willingness to recommend their landlord, and clear
documentation and efficient legal process improve occupiers’ perception of receiving ‘Value for Money’.
Research Limitations - The sample is skewed towards occupiers of prime office buildings in the UK, owned
by landlords who care sufficiently about their tenants to commission studies into occupier satisfaction.
Practical implications - This research should help to improve the landlord – tenant relationship, benefitting
the businesses that rent property and helping building managers understand where to focus their efforts to
achieve maximum effect on occupier satisfaction, loyalty and advocacy.
Originality/value - There has been little academic research into the determinants of satisfaction of occupiers of UK commercial property. This large-scale study enables the most influential factors to be identified and
prioritised
Ecosystem Management in Pasture Communities: Tools from Restoration Ecology
Pasture systems have the potential to improve both economic and environmental sustainability in agricultural communities worldwide. To achieve maximum benefits, pasture plant communities must be tailored to the climate, the site type and the goals of the producer. Little is known about how to accomplish this, beyond very broad recommendations. We approached the problem by adapting a three-step conceptual framework from restoration ecology for use in managed pasture communities of the northeastern United States. The three steps, inventory, assessment and remediation, were designed for managers interested in restoring degraded native ecosystems, but can be applied equally well in managed ecosystems
