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...

This paper reports on the implementation of a semester-long task in a university lower intermediate Chinese language course. Web-based podcasting technology, ChinesePod, was utilized to assist this implementation. The first part of this paper focuses on the task design informed by frameworks proposed in the literature. The second half of the paper presents and analyses data collected from an en...

Many-Task Computing (MTC) is a widely used computing paradigm for large-scale task-parallel processing. One of the key issues in MTC is to schedule a large number of independent tasks onto heterogeneous resources. Traditional task-level scheduling heuristics, like Min-Min, Sufferage and MaxStd, cannot readily be applied in this scenario. As most of MTC tasks are usually fine-grained, the resour...

the necessity and importance of teaching pragmatics has come to light by many researchers (e.g. rose & kasper, 2001). due to the consensus over the need to teach pragmatic competence, the main issue now centers on the question of how we should teach this competence in the most effective way. consistent with this line of research, the present study aimed to investigate the effectiveness of d...

AIM To examine the application of core concepts from Complexity Theory to explain the findings from a process evaluation undertaken in a trial evaluating implementation strategies for recommendations about reducing surgical fasting times. BACKGROUND The proliferation of evidence-based guidance requires a greater focus on its implementation. Theory is required to explain the complex processes ...
