Email has come to play a central role in task management, yet email tool features have remained relatively static in recent years, lagging behind users? evolving practices. The Taskmaster system narrows this gap by recasting email as task management and embedding task-centric resources directly in the client. In this paper, we describe the field research(More)
It is widely acknowledged that many professionals suffer from “e-mail overload.” This articlepresents findings fromin-depth fieldwork that examined thisphenomenon, uncovering six key challenges of task management in e-mail. Analysis of qualitativeandquantitativedata suggests that it is not simply thequantitybut also thecolHUMAN-COMPUTER INTERACTION, 2005,(More)
Sleep-disordered breathing and excessive sleepiness may be more common in commercial vehicle drivers than in the general population. The relative importance of factors causing excessive sleepiness and accidents in this population remains unclear. We measured the prevalence of excessive sleepiness and sleep-disordered breathing and assessed accident risk(More)
OBJECTIVES Sleep deprivation and alcohol both impair driving performance. This study assessed the interactive effect of low-dose alcohol and extended wakefulness. DESIGN Repeated-measures, crossover design evaluating psychomotor and driving function in a non-sleep-deprived state and after extended wakefulness with and without low-dose alcohol. SETTING(More)
Sleep-related breathing disorders encompass a range of disorders in which abnormal ventilation occurs during sleep as a result of partial or complete obstruction of the upper airway, altered respiratory drive, abnormal chest wall movement, or respiratory muscle function. The most common of these is obstructive sleep apnea (OSA), occurring in both adults and(More)
Mobile phone exposure-related effects on the human electroencephalogram (EEG) have been shown during both waking and sleep states, albeit with slight differences in the frequency affected. This discrepancy, combined with studies that failed to find effects, has led many to conclude that no consistent effects exist. We hypothesised that these differences(More)
OBJECTIVES To assess outcomes in patients with spinal cord injury (SCI) and a tracheostomy tube (TT), before and after the introduction of a tracheostomy review and management service (TRAMS) for ward-based patients. DESIGN Matched-pairs design with two cohorts, before and after the intervention. SETTING 900-bed tertiary hospital in Melbourne, Victoria.(More)
About 1.5 million Australians are shift workers. Shift work is associated with adverse health, safety and performance outcomes. Circadian rhythm misalignment, inadequate and poor-quality sleep, and sleep disorders such as sleep apnoea, insomnia and shift work disorder (excessive sleepiness and/or insomnia temporally associated with the work schedule)(More)
Software can be tested either manually or automatically. The two approaches are complementary: automated testing can perform a large number of tests in little time, whereas manual testing uses the knowledge of the testing engineer to target testing to the parts of the system that are assumed to be more error-prone. Despite this complementarity, tools for(More)
We investigate the persistence probability in the Voter model for dimensions d ≥ 2. This is achieved by mapping the Voter model onto a continuum reaction–diffusion system. Using path integral methods, we compute the persistence probability r(q, t), where q is the number of “opinions” in the original Voter model. We find r(q, t) ∼ exp[−f2(q)(ln t) 2] in d =(More)
