Overview of building information modelling in healthcare projects

In this paper, we explore how BIM functionalities together with novel management concepts and methods have been utilized in thirteen hospital projects in the United States and the United Kingdom. Secondary data collection and analysis were used as the method. Initial findings indicate that the utilization of BIM enables a holistic view of project delivery and helps to integrate project parties into a collaborative process. The initiative to implement BIM must come from the top down to enable early involvement of all key stakeholders. It seems that it is rather resistance from people to adapt to the new way of working and thinking than immaturity of technology that hinders the utilization of BIM

A review of tertiary BIM education for advanced engineering communication with visualization

SPECT with Tc-99m-labeled agents is better able to detect viability after nitrate administration. Nitrates induce vasoclilation and may increase blood flow to severely hypoperfused but viable myocardium, thereby enhancing tracer delivery and improving the detection of viability. Quantitative data on the changes in blood flow are lacking in SPECT but can be provided by PET. The aim of the present study was to use PET to evaluate whether nitrate administration increases blood flow to chronically dysfunctional but viable myocardium. Methods: N-13-Ammonia PET was used to quantitatively assess blood flow, and F-18-FDG PET was used as the gold standard to detect viable myocardium. Twenty-five patients with chronic ischemic left ventricular dysfunction underwent N-13-ammonia PET at rest and after nitrate administration. Results: A significant increase in nitrate-enhanced blood flow was observed in viable segments (from 0.55 +/- 0.15 to 0.68 +/- 0.24 mL/min/g, P <0.05). No statistically significant change in blood flow was observed in nonviable segments (0.60 +/- 0.20 vs. 0.55 +/- 0.18 mL/min/g). A ratio of at least 1.1 for nitrate-enhanced flow to resting flow allowed optimal detection of viable myocardium, yielding a sensitivity of 82% with a specificity of 100%. Conclusion: N-13-Ammonia PET showed a significant increase in nitrate-enhanced blood flow in viable myocardium, whereas blood flow remained unchanged after nitrate administration in nonviable myocardium. Nitrate use during myocardial perfusion imaging will lead to improved assessment of myocardial viability

A multi-disciplinary perspective on emergent and future innovations in peer review [version 1; peer review: 2 approved with reservations]

Peer review of research articles is a core part of our scholarly communication system. In spite of its importance, the status and purpose of peer review is often contested. What is its role in our modern digital research and communications infrastructure? Does it perform to the high standards with which it is generally regarded? Studies of peer review have shown that it is prone to bias and abuse in numerous dimensions, frequently unreliable, and can fail to detect even fraudulent research. With the advent of Web technologies, we are now witnessing a phase of innovation and experimentation in our approaches to peer review. These developments prompted us to examine emerging models of peer review from a range of disciplines and venues, and to ask how they might address some of the issues with our current systems of peer review. We examine the functionality of a range of social Web platforms, and compare these with the traits underlying a viable peer review system: quality control, quantified performance metrics as engagement incentives, and certification and reputation. Ideally, any new systems will demonstrate that they out-perform current models while avoiding as many of the biases of existing systems as possible. We conclude that there is considerable scope for new peer review initiatives to be developed, each with their own potential issues and advantages. We also propose a novel hybrid platform model that, at least partially, resolves many of the technical and social issues associated with peer review, and can potentially disrupt the entire scholarly communication system. Success for any such development relies on reaching a critical threshold of research community engagement with both the process and the platform, and therefore cannot be achieved without a significant change of incentives in research environments

We’ve got something for everyone: How individual differences predict different blogging motivations

The principal aims of this study were to develop a Blogging Motivations Questionnaire (BMQ) and to test the hypothesis that sex, age, and personality would be associated with individual blogging motivations. One hundred and sixty bloggers completed the BMQ and the International Personality Item Pool (Goldberg, 1999). Six motivations for writing blogs were confirmed: personal revelation, emotional outlet, creative outlet, selective disclosure, social networking and advertising. Conscientiousness predicted the ‘social networking’ motivation, Agreeableness predicted ‘selective disclosure’ and Openness ‘creative outlet’. Women were motivated by ‘selective disclosure’, and men for ‘advertising’ and as an ‘emotional outlet’. Finally, older bloggers were motivated to use their blogs as a ‘creative outlet’. With reference to the Uses and Gratifications paradigm, it is likely that bloggers actively construct blogs to satisfy very personal needs. Moreover, the types of needs that one wishes to satisfy are likely to vary with personality type and with one’s age and sex.University of Wolverhampto

KanBIM workflow management system: Prototype implementation and field testing

Research Question: can a BIM-based workflow information system help construction personnel implement lean pull flow strategies? If so, how, and to what extent? Purpose: to test a prototype system in the field, measure and monitor its impact, and evaluate and discuss the implications. Research Method: we have implemented an early prototype of a novel workflow management information system for construction, called ‘KanBIM’, and tested it on a large residential construction site in three stages. Findings: the main significance of the results lies in the site personnel’s positive experience with the system and their observations of the ways in which it could influence the behavior and productivity of crews. These included recognition of the effect the system had in encouraging well-informed discussion and negotiation between crews concerning coordination of work. Limitations: although PPC and other quantitative measures were collected, the duration of the field tests and the depth of integration in company information systems insufficient to provide conclusive results. Implications: while the results are positive and indicate the value of BIM-enabled process flow control, further development and testing is needed. Value for researchers and practitioners: the prototype and the findings are an essential guide for future development of lean process flow control systems. We identify specific benefits a full implementation could bring to subcontractor trade managers, superintendents and other project management functions

Field tests of the KanBIM™ lean production management system

The KanBIM™ system is designed to support lean work flow control on construction sites. It facilitates short-term work planning and monitoring, providing clear visualization of the maturity of tasks planned and the status of work under way. The goal of the KanBIM research is to determine whether a BIM based workflow information system can help construction personnel implement lean pull flow strategies. An early prototype of system, with field reporting interfaces, a central database and a building information model, was implemented and tested on a large residential construction site. Although PPC and other results were measured, the main significance of the results lie in the site personnel's positive experience with the system and their observations of the ways in which it could influence the behaviour and productivity of crews. These included recognition of the strong impact the system had in encouraging well-informed discussion and negotiation between crews concerning coordination of their work. The participants identified specific benefits a full implementation could bring to subcontractor trade managers, superintendents and various project management functions
