Background:Over a decade ago, the Hill report argued that a shift in vision was required to change the perception of National Health Service (NHS) Library and Knowledge Services (LKS) in England from “book repositories” to essential services that underpin clinical decision-making by patients, carers, and health care professionals. Health Education England''s Knowledge for Healthcare: A Development Framework for Library and Knowledge Services in England 2015–2020 advocates embedding librarians within clinical and management teams in order to provide access to high-quality evidence at the point of need.Case Presentation:In April 2019, Royal Papworth Hospital relocated twelve miles from its historic village location in Papworth Everard to its new state-of-the-art hospital on the Cambridge Biomedical Campus. The design for this new hospital did not accommodate a traditional library space and therefore necessitated a transformation of the LKS. The organization opted to embed the LKS staff into the clinical setting and relegate 80% of the print collection to off-site storage. This project and its associated steps are presented as an example of health care library transformation.Conclusion:Embedding the LKS team in the clinical setting, engaging in proactive outreach activity, and improving our marketing led to a 44% increase in literature searches requested compared to the same eleven-month period in the previous year. A 40% decrease in our print book loans indicates additional barriers to using a click-and-collect service and the need for greater investment in our e-book provision. However, early outcomes for our best-fit service transformation are positive. Having an open, dual mindset has enabled the service to embrace change and maximize emerging opportunities to collaborate with clinical staff on new projects. 相似文献

This paper considers two paradigms of process-aware information systems (PAIS) that are used to share knowledge about planning and executing tasks. The case-based task management (CBTM) system is based on the transduction of execution protocols, so-called cases; and the pattern-based task management (PBTM) system is based on task patterns that are derived from cases but yield more abstract information. As user motivation to contribute to a collaborative task management system is a crucial factor for its success, we consider the different motivational requirements of CBTM and PBTM from a psychological point of view. Based on experimental findings about different factors that have been shown to enhance people's motivation to contribute their knowledge to a shared pool, we compare the two approaches and assess which one is more appropriate with respect to motivation. 相似文献

Multirater feedback, often called 360‐degree feedback, is a popular development and assessment tool, especially for organizational leaders. Raters from different organizational levels, including subordinates, boss, peers, and self, rate the leader's performance. However, there seldom is strong agreement across rater groups. This study used the data from a commercially available 360‐degree leader development feedback instrument and a second‐order confirmatory factor analysis model to try to explain the differences in ratings between the groups. Rather than an explanation of the differences, what was found were two second‐order factors that may be the underlying elements that all raters consider when observing leader performance. 相似文献

The authors contend that the equity and advocacy expectations imbedded in the legal mandate for parent participation in the special education decision-making process directly contradict the hierarchy of professional status and knowledge on which the positivist paradigm of professionalism is based, and are also in conflict with the values held by many families from culturally diverse backgrounds, contributing to low levels of participation and advocacy. They argue the need for professional education to incorporate opportunities for professionals to identify the cultural assumptions imbedded in the field of special education towards more balanced and effective collaboration. 相似文献

Trichloroacetic acid (TCA) solubilized and DEAE fractionatedMycobacterium tuberculosis H37Ra excretory-secretory (ES) antigen viz., Mtb EST DE1 and affinity purified goat antibodies to the TCA solubilized ES antigen
(Mtb EST) were explored in detecting tubercular antibody and antigen respectively in sera of bone and joint tuberculosis by
indirect and sandwich ELISA. Out of total 36 bone & joint tuberculosis cases, tubercular antibody was detected by indirect
ELISA in 30 patients (sensitivity 83%), while circulating tubercular antigen was detected by sandwich ELISA in 27 patients
(sensitivity 75%). Out of 34 non tubercular disease control cases, 10 patients showed positive reaction for antibody while
only 4 patients showed positive reaction for antigen. In another group of 34 healthy subjects who were screened, 4 individuals
showed positive reaction for tubercular antibody and 2 cases for antigen. This study shows that antigen detection assay using
affinity purified anti Mtb EST antigen antibody is superior with overall specificity of 91% as compared to antibody detection
assay with 75% specificity in bone & joint tuberculosis. 相似文献

Alpha-1-antitrypsin deficiency is a hereditary disease leading to hepatitis and cirrhosis. It is the most common genetic cause
of liver disease in children which must inherit the tendency from both parents to develop. It acquires the highest priority
in the differential diagnosis in a child with chronic liver disease. In this case report we substantiate the role of serum
protein electrophoresis, in diagnosing alpha-1-antitrypsin deficiency. 相似文献

This paper uses results from a national survey of teachers in England to test a hypothesised model of teacher orientation to learning (consisting of beliefs, practice and experiences about learning) and its relationship to teacher learning change. Results from a structural equation modeling process of 1126 teacher survey responses show that teachers bring an internal, external and collaborative orientation to their professional learning. The beliefs and practices associated with these orientations are also shown to have a moderate influence, via path analysis, on teacher learning change defined as a composite outcome of change in beliefs, practices and students. 相似文献
