Edge caching and Dynamic Vision Sensing for low delay access to visual medical information.

A new system is proposed to reduce the transmission delay of visual and non-visual medical records by using edge caching and Dynamic Vision Sensing (DVS) technologies. The results of simulation show that the proposed scheme can decrease the transmission delay by 36.35% to 86.

Exchanging implements: the micro-materialities of multidisciplinary work in the operating theatre.

Surgical procedures rely upon an array of commonplace tools, implements and materials that mediate practice and disciplinary collaboration within the operating theatre. Substantial time is dedicated to the issue and provision of these artefacts and their timely exchange is critical to the successful accomplishment of surgical procedures. In this article, we consider the practice, knowledge and agency that informs how particular implements and materials are passed by the scrub nurse to the surgeon that in turn enables their deployment with regard to the particular procedure and the contingencies 'at hand'.

Embedding instruction in practice: contingency and collaboration during surgical training.

In this paper we address the ways in which surgeons, in collaboration with other members of the surgical team, create occasions for demonstration and instruction within the highly complex and demanding tasks of a surgical operation. Drawing on video recordings of surgical operations, augmented by field studies, we examine how particular phenomena and procedures are made accessible and intelligible to trainees and the ways in which brief episodes of insight and instruction enable complex procedures to be followed and understood. We consider the ways in which demonstration and instruction are achieved, whilst preserving the integrity of medical practice, and explore how trainees are provided with the opportunity to witness, and learn from, the contingent deployment of formal procedures in particular cases.

Ordering competition: the interactional accomplishment of the sale of art and antiques at auction.

Auctions provide an institutional solution to a social problem; they enable the legitimate pricing and exchange of goods where those goods are of uncertain value. In turn, auctions raise a number of social and organizational issues that are resolved within the interaction that arise in sales by auction. In this paper, we examine sales of fine art, antiques and objets d'art and explore the ways in which auctioneers mediate competition between buyers and establish a value for goods.

Video and qualitative research: analysing medical practice and interaction.

Context: Video has long been recognised as providing an important resource within medical education, particularly, perhaps, for training in primary health care. As a resource for research, and more specifically within qualitative social science studies of medical practice, video has proved less pervasive, despite its obvious advantages.

Methods: In this paper, we sketch an approach to using video to inform the analysis of medical practice and the ways in which health care is accomplished through social interaction and collaboration.

Technology and medical practice.

One of the most significant developments in healthcare over the past 25 years has been the widespread deployment of information and communication technologies. These technologies have had a wide-ranging impact on the organisation of healthcare, on professional practice and on patients' experience of illness and its management. In this paper we discuss the ways in which Sociology of Health and illness has provided a forum for the analysis of these new technologies in healthcare.

Overseeing organizations: configuring action and its environment.

Despite the widespread deployment of CCTV through most major cities and towns in great Britain, and the importance of surveillance to contemporary debates within the social sciences, there remains relatively little detailed research concerned with the practical use of these technologies in the workplace. In this paper, we examine how personnel in the operation rooms in London Underground use CCTV and related equipment to identify problems and events and to develop a co-ordinated response. In particular, we consider how personnel configure scenes to make sense of and interpret the conduct of the travelling public in organizationally relevant ways, and how they shape the ways in which both passengers and staff see and respond to each others' actions.

Technology and social interaction: the emergence of 'workplace studies'.

Despite the substantial body of literature concerned with the ways in which digital media are transforming contemporary society and institutional life, we have relatively little understanding of the ways in which new technologies feature in day to day organizational conduct and interaction. There is however a growing corpus of empirical research which places the situated and contingent character of new technologies at the heart of the analytic agenda, but as yet, these studies are relatively little known within sociology. They include ethnographies of command and control centres, financial institutions, the news media, and the construction industry.

How do desk-top computers affect the doctor-patient interaction?

General practice consultations were video-recorded before and after the introduction of a desk-top computer system into the practice. The recordings were analysed by detailed qualitative scrutiny of tape and transcripts (conversation analysis) to discover regular patterns of interaction. This analysis confirmed that the introduction of computers into the consultation had a significant impact on the communication between patient and doctor.

Control of manufacture--principles and purposes.

The control of manufacture is centred on the assessment of the operation based on information supplied by the manufacturer and on detailed physical inspection. The purpose of controlling manufacture is to ensure, as far as practicable, that products are manufactured within premises, and by processes and personnel, of such standard that the quality of the final product is assured. The required standards are written in the "Guide to Good Manufacturing Practice for Medicinal Products", and its several supplementary guidelines, so in practical terms the purpose of inspection is to assess compliance with these guidelines.

The serological response of calves to Leptospira interrogans serovar hardjo vaccines and infection as measured by the microscopic agglutination test and anti-IgM and anti-IgG enzyme-linked immunosorbent assay.

The microscopic agglutination test (MAT) and the anti-IgM and anti-IgG enzyme-linked immunosorbent assays (ELISA) were used to examine sera taken over the course of 16 weeks from 35 calves vaccinated and/or infected with Leptospira interrogans serovar hardjo. The relationship between the IgM and IgG responses to vaccination and infection were determined. The rapid and high rise in IgM levels following challenge made the anti-IgM ELISA a potentially good indicator of recently established infection although some transitory high levels were seen where infection did not become established.

Inactivated canine parvovirus vaccines: an alternative method for assessment of potency.

Groups of three-week-old chickens were given graded doses of inactivated canine parvovirus vaccines. Blood samples were taken three weeks later and the sera examined by ELISA for antibodies to canine parvovirus. Reproducible, linear, log-dose serological responses were observed, enabling the potency of the vaccines to be compared.

Serology-based potency test for inactivated Newcastle disease vaccines.

Twenty-seven inactivated oil-emulsion Newcastle disease vaccines were tested for potency in chickens. Serum samples from groups given 1/50 dose of vaccine were examined by the haemagglutination inhibition (HI) test and the indirect enzyme-linked immunosorbent assay (ELISA). Good correlations were observed between potency and HI titres and between potency and ELISA absorbance.

Canine parvovirus serology: a collaborative assay.

Fifteen laboratories were supplied with coded samples of canine sera for testing for the presence of antibodies against canine parvoviruses. One of these sera had been designated as a potential British standard canine parvovirus antiserum. Most of these laboratories were either providing a canine parvovirus serology service, or represented pharmaceutical companies which manufacture canine parvovirus vaccines for the United Kingdom market.

Efficacy of porcine parvovirus vaccines.

Three inactivated porcine parvovirus vaccines were tested for efficacy in 66 susceptible gilts. The gilts were challenged with virulent virus on the 40th day of gestation. All the vaccines provided excellent protection against fetal mortality despite insignificant serological responses to one of them.
