Accounting for knowledge embedded in physical objects and environments : the role of artefacts in transferring knowledge
The intention to investigate the role of artefacts (objects and environments) in codifying, embedding and disseminating knowledge was inspired by an awareness that organisations across all sectors are increasingly being asked not only to provide products in the first instance, but also to support them throughout their service life. Thus a move from product-delivery to product-service designs is suggested. This paper considers ways in which knowledge can be embedded into the physical properties of artefacts and how this can consequently aid the dissemination and management of knowledge in and across stages of life cycles. A literature review and fieldwork based on an ethnomethodological approach are used to investigate this topic. Accounts of the situated meaning of artefacts within social processes are obtained using ethnographic armchair research. Unique adequacy is used to achieve an understanding of how people make sense of artefacts. The initial findings of the current research show that knowledge can be embedded or encoded into the physical properties of artefacts and that this can be successfully transferred from artefact to user
Facilitators and barriers to the integration of healthcare service and building design
Service design research recognises the importance of infrastructure design in the
achievement of streamlined service delivery. Although research about service design
and building design is abundant, very little is known about the integration of these
processes. Therefore, this research aimed at identifying facilitators and barriers to the
integration of service and building design processes. To this end, the initial results
from a historical investigation of the redevelopment of a hospital in Salford, UK were
used to identify facilitators and barriers to the integration of service and building
design. Data was collected through interviews, document analysis and a workshop.
Initial results present internal and external factors related to the design process
generating barriers to integration of service and building design
The gaps between healthcare service and building design : a state of the art review
Healthcare buildings are designed to achieve diverse objectives, ranging from providing appropriate environments where care can be delivered to communities to increasing operational efficiency and improving patient flows and the patient experience. Improvements in
operational efficiency should result from state-of-the-art buildings, more appropriate layouts, departmental adjacencies, efficient clinical and business processes and enhanced information systems. However, complexities around requirements and stakeholders management may prevent the achievement of such objectives. The aim of this article is to identify and understand how healthcare services (re)design and building design can be integrated to facilitate increased performance both in terms of service delivery and future changes. Findings indicate that current approaches and innovation are restricted due to functional barriers in the design process, and that there is a need to support the development of operations driven design through time (e.g. flexible and durable) that satisfies diverse needs
Study of transient behavior of finned coil heat exchangers
The status of research on the transient behavior of finned coil cross-flow heat exchangers using single phase fluids is reviewed. Applications with available analytical or numerical solutions are discussed. Investigation of water-to-air type cross-flow finned tube heat exchangers is examined through the use of simplified governing equations and an up-wind finite difference scheme. The degenerate case of zero air-side capacitance rate is compared with available exact solution. Generalization of the numerical model is discussed for application to multi-row multi-circuit heat exchangers
The Claims Culture: A Taxonomy of Industry Attitudes
This paper presents an analysis of a familiar aspect of construction industry culture that we have dubbed 'the claims culture'. This is a culture of contract administration that lays a strong emphasis on the planning and management of claims. The principal elements of the analysis are two sets of distinctions. The first comprises economic and occupational orders, referring to two kinds of control that are exercised over the construction process; predicated respectively on economic ownership and occupational competence. The second refers to contrasting attitudes towards relationships and problem solving within these orders: respectively 'distributive' and 'integrative'. The concepts of economic and occupational order entail further sub-categories. The various attitudes associated with these categories and sub-categories are described. They are assessed as to their consequences for change initiatives in the industry
Metabolomic changes in polyunsaturated fatty acids and eicosanoids as diagnostic biomarkers in Mycobacterium avium ssp. paratuberculosis (MAP)-inoculated Holstein–Friesian heifers
Mycobacterium avium subspecies paratuberculosis (MAP) is the causative organism of Johne’s disease, a chronic granulomatous enteritis of ruminants. We have previously used naturally MAP-infected heifer calves to document metabolomic changes occurring in MAP infections. Herein, we used experimentally MAP-inoculated heifer calves to identify biomarkers for MAP infections. At 2-weeks of age, 20 Holstein–Friesian (HF) calves were experimentally inoculated with MAP. These calves, along with 20 control calves, were sampled biweekly up to 13-months of age and then monthly up to 19-months of age. Sera were assessed using flow infusion electrospray high-resolution mass spectrometry (FIE-HRMS) on a Q Exactive hybrid quadrupole-Orbitrap mass spectrometer for high throughput, sensitive, non-targeted metabolite fingerprinting. Partial least squares-discriminate analysis (PLS-DA) and hierarchical cluster analysis (HCA) discriminated between MAP-inoculated and control heifer calves. Out of 34 identified metabolites, six fatty acyls were able to differentiate between experimental groups throughout the study, including 8, 11, 14-eicosatrienoic acid and cis-8, 11, 14, 17-eicosatetraenoic acid which were also detected in our previous study and so further suggested their value as biomarkers for MAP infection. Pathway analysis highlighted the role of the alpha-linoleic acid and linoleic acid metabolism. Within these pathways, two broad types of response, with a rapid increase in some saturated fatty acids and some n-3 polyunsaturated fatty acids (PUFAs) and later n-6 PUFAs, became predominant. This could indicate an initial anti-inflammatory colonisation phase, followed by an inflammatory phase. This study demonstrates the validity of the metabolomic approach in studying MAP infections. Nevertheless, further work is required to define further key events, particularly at a cell-specific level.
