Abstract: This paper discusses the results of a survey of ES producers conducted between October 1987 and June 1988 as part of a British Library Research and Development Department funded project. The survey aimed to establish the nature and scope of ES projects in Britain, the skills and methodologies used in their development and the background and experience of the personnel employed to develop them. A major part of the survey focused on the human input and organisational impact of ESs and this paper summarises the findings of the survey with particular reference to these issues. It includes details of the organisational background of those working in the area; a review of the nature, number and scope of ES projects in Britain; consultation procedures with both users and experts; the knowledge engineering task and methodologies currently used in undertaking it; the skills and attributes of the knowledge engineer; issues of updating and extending ESs; and hopes, projections and expectations for the future. 相似文献

Symbolic analysis is of paramount importance for parallelizing compilers and performance estimators to examine symbolic expressions with program unknowns such as machine and problem sizes and to solve queries based on systems of constraints (equalities and inequalities). This paper describes novel techniques for counting the number of solutions to a system of constraints, simplifying systems of constraints, computing lower and upper bounds of symbolic expressions, and determining the relationship between symbolic expressions. All techniques target wide classes of linear and non-linearsymbolic expressions and systems of constraints. Our techniques have been implemented and are used as part of a parallelizing compiler and a performance estimator to support analysis and optimization of parallel programs. Various examples and experiments demonstrate the effectiveness of our symbolic analysis techniques. 相似文献

In this paper, we analyse physicians’ and nurses’ practices of prescribing and administering medication through the use of
paper-based, and digitalized medication plans. Our point of departure is an ethnographic study of the implications of upgrading
an electronic medication module (EMM) that is part of an electronic health record (EHR), carried out at an endocrinology department.
The upgrade led to a temporary breakdown of the EMM, and a return to paper-based medication plans. The breakdown made visible
and noticeable the taken-for-granted capabilities of medication plans in their paper-based and digital versions, and the distribution
of functionalities between medication plans and clinicians. We see the case as an opportunity to analyse infrastructuring
in health care, the process by which medical practices and artefacts become parts of social and technological networks with
longer reaches and more channels through which coordination among distributed actors is enabled and formed. In this case,
infrastructuring means an extended scope and intensity of the coordinative capabilities of medication plans, and an increased
vulnerability to, and dependency on events outside the immediate loci of interaction. We particularly note the capacity of
the EMM to facilitate different kinds of ordering of information and practices, and propose the conceptualizing of such digitalized
artefacts as ‘ordering devices’. Ordering devices order information, stipulate action, and coordinate interaction across and
within social worlds, and achieve this through the flexible support of different kinds of ordering. 相似文献

This is an account of the origins of the concept of social mentoring and development of a social mentoring project in a local
community in the city of Brighton and Hove in the UK. The account highlights the potential of social intervention for investigating
the gaps and opportunities for mentoring services for people living with Asperger Syndrome. This initiative provides a model
for supporting a parallel dialogue alongside and beyond the practice initiative so as to create a space for reflection on
the impact and the broader application of the intervention. This project was made possible by the commitment and tenacity
of a number of local community activists and welfare entrepreneur’s on the ground who were able to set in train a number of
events. These events are mapped out starting with community concerns, campaign initiatives, survey of the area of need and
the use of evidence to secure funding and establish a client specific city-wide initiative. The role and importance of establishing
alliances between the community and the local university academic community through a participatory research approach is highlighted
and the benefits of creating space for the sharing of evidence from the literature and squaring this with evidence from practice
through the development of a wider community of practice network is discussed. The resulting knowledge synthesis regarding
the differentiation between mentoring, social mentoring and befriending is presented.
