Space, conversations and place: lessons and questions from organisational development

Physical workspace is distinguished from workplace. The latter embodies culture and should become the greater concern of FM. In the field of individual and group development spaces can add an extra gear to stimulate cognitive processes. We provide various examples and suggest modern workplaces, with their emphasis on interaction need to also focus on environments and spaces for individual and collective reflection

Integrated electronic prescribing and robotic dispensing: a case study

INTRODUCTION: To quantify the benefits of electronic prescribing directly linked to a robotic dispensing machine. CASE DESCRIPTION: Quantitative case study analysis is used on a single case. Hospital A (1,000 beds) has used an integrated electronic prescribing system for 10 years, and in 2009 linked two robotic dispensing machines to the system. The impact on dispensing error rates (quality) and efficiency (costs) were assessed. EVALUATION AND DISCUSSION: The implementation delivered staff efficiencies above expectation. For the out-patient department, this was 16% more than the business case had suggested. For the in-patients dispensary, four staff were released for re-deployment. Additionally, £500,000 in stockholding efficiency above that suggested by the business case was identified. Overall dispensing error rates were not adversely affected and products dispensed by the electronic prescribing - robot system produced zero dispensing errors. The speed of dispensing increased also, as the electronic prescribing - robot combination permitted almost instantaneous dispensing from the point of a doctor entering a prescription. CONCLUSION: It was significant that the combination of electronic prescribing and a robot eliminated dispensing errors. Any errors that did occur were not as a result of the electronic prescribing - robotic system (i.e. the product was not stocked within the robot). The direct linking of electronic prescribing and robots as a dispensing system together produces efficiencies and improves the quality of the dispensing process

Run Time Approximation of Non-blocking Service Rates for Streaming Systems

Stream processing is a compute paradigm that promises safe and efficient parallelism. Modern big-data problems are often well suited for stream processing's throughput-oriented nature. Realization of efficient stream processing requires monitoring and optimization of multiple communications links. Most techniques to optimize these links use queueing network models or network flow models, which require some idea of the actual execution rate of each independent compute kernel within the system. What we want to know is how fast can each kernel process data independent of other communicating kernels. This is known as the "service rate" of the kernel within the queueing literature. Current approaches to divining service rates are static. Modern workloads, however, are often dynamic. Shared cloud systems also present applications with highly dynamic execution environments (multiple users, hardware migration, etc.). It is therefore desirable to continuously re-tune an application during run time (online) in response to changing conditions. Our approach enables online service rate monitoring under most conditions, obviating the need for reliance on steady state predictions for what are probably non-steady state phenomena. First, some of the difficulties associated with online service rate determination are examined. Second, the algorithm to approximate the online non-blocking service rate is described. Lastly, the algorithm is implemented within the open source RaftLib framework for validation using a simple microbenchmark as well as two full streaming applications.Comment: technical repor

Inherent-Structure Dynamics and Diffusion in Liquids

The self-diffusion constant D is expressed in terms of transitions among the local minima of the potential (inherent structure, IS) and their correlations. The formulae are evaluated and tested against simulation in the supercooled, unit-density Lennard-Jones liquid. The approximation of uncorrelated IS-transition (IST) vectors, D_{0}, greatly exceeds D in the upper temperature range, but merges with simulation at reduced T ~ 0.50. Since uncorrelated IST are associated with a hopping mechanism, the condition D ~ D_{0} provides a new way to identify the crossover to hopping. The results suggest that theories of diffusion in deeply supercooled liquids may be based on weakly correlated IST.Comment: submitted to PR

University libraries and the postgraduate student: Physical and virtual spaces

Purpose – This study aims to examine the library/information issues affecting graduate students, both those on taught courses and those undertaking research. It seeks to focus specifically on their perceptions of the value to them of physical and digital resources and spaces, and how well their needs were being met. Design/methodology/approach – An online questionnaire survey of students was complemented by a series of face-to-face interviews with library staff. Findings – This group of students are different from undergraduates, whose information behaviour has more often been studied. They require silent study space, are enthusiastic book borrowers, and have limited interest in social media in the library. They have a strong requirement for digital resources and IT support, and are not inclined to ask for assistance from librarians. Research limitations/implications – The study is limited to three English universities, although they are sufficiently varied in nature to make the results more widely applicable. Practical implications – The survey provides evidence for librarians in universities and colleges serving graduate students as to the best form of provision, and for any library seeking to make best use of its space as resources become increasingly digital. Originality/value – This is one of the few studies to examine the information behaviour and needs of advanced students. It contributes to the debate on the future of the library as place in a digital age
