BACKGROUND Chlamydia trachomatis (chlamydia) is the most commonly diagnosed sexually transmitted infection (STI) in England; approximately 70% of diagnoses are in sexually active young adults aged under 25. To facilitate opportunistic chlamydia screening in general practice, a complex intervention, based on a previously successful Chlamydia Intervention Randomised Trial (CIRT), was piloted in E...

Medical simulation is a new method of education in medicine. It allows training medical students or practitioners without the need to involve patients and makes them familiar with various kinds of examinations, especially related to medical imaging. Simulators that visualize examinations or operations require large computing power to keep time constraints of output presentation. A common approa...

To err is human. Clinical practice guidelines (CPGs) are often not followed and lead to adverse outcomes. The issue on implementation of CPG is complex. A review of CPG implementation is done to identify the barriers and enablers. For the first time, a fishbone diagram is used to delineate the root-causes. And Haddon matrix is applied to help understand the complexity of evidence-based implemen...

The aim of this study was to explore participants' experiences and opinions about a free-choice system in relation to policy objectives articulated by the national government and local authorities. A case study was conducted. Thirty-five informants participated. Qualitative interviews were undertaken. Results are discussed on how to address different dimensions of choice, not only where, but al...

Let HilbS be the Hilbert scheme of g points on a K3 surface S. Suppose that PicS = ZC where C is a smooth curve with C = 2(g − 1)n. We prove that HilbS is a Lagrangian fibration.

Scientific reasoning is a key skill in academic contexts and may be trained with interactive learning tasks, that require learners to explicitly give reasons for their solution. We provide a general, mathematically motivated algebraic model for reasoning tasks that enables computer-based analysis of answers and feedback generation, especially in the case of tasks that have distinct permissible ...

The NTP network is an important part of the Internet’s infrastructure, and one of the most challenging times for the NTP network is around leap seconds. In this paper we look at the behaviour of public servers in the NTP network in 2005 and over the period from 2008 to present, focusing on leap seconds. We review the evolution of the NTP reference implementation with respect to leap seconds and...

Reasons for a successful or unsuccessful implementation of infection prevention and control (IPC) guidelines are often multiple and interconnected. This article reviews key elements from the national to the individual level that contribute to the success of the implementation of IPC measures and gives perspectives for improvement. Governance approaches, modes of communication and formats of gui...
