Two experiments were carried out to examine the effect of interruption position and interruption duration on postcompletion error (PCE) occurrences in a game-like procedural task. Experiment 1 showed a significant main effect of interruption position on PCE rate; significantly more PCEs were obtained when the interruption occurred just before the PC step than interruptions at any other position...

User’s cognitive state is extremely fragile and sensitive to external interruption, especially when a user is performing a cognitively-taxing task. Given that interruptions frequently occur during human-computer interaction, and given the relative scarcity of human attention and their vulnerability to interruptions, interruption-resistance is needed to be considered when designing user interfac...

We examine people’s strategic cognitive responses to being interrupted while performing a task. Based on memory theory, we propose that resumption of a task after interruption is facilitated by preparation during the interruption lag, or the interval between an alert to a pending interruption (e.g. the phone ringing) and the interruption proper (the ensuing conversation). To test this proposal,...

this paper analyzes a renewal input  working vacations queue with change over times and bernoulli schedulevacation interruption under (a,c,b) policy.the service and vacation times are exponentially distributed.the server begins service if there are at least c units in the queue and the service takes place in batches with a minimum of size a and a maximum of size b (a

Introduction Interruption of enteral nutrition (EN) is common in the intensive care unit (ICU). Frequent episodes of EN interruption can lead to protein and calorie debt with a potential impact on outcomes in critically ill patients [1,2]. However, few studies have investigated the details of EN interruption practice including the reasons and duration of the interruption [3,4]. A standard proto...

background: the presence of small intestine in the radiation field during pelvic cancers treatment causes an interruption in radiotherapy. a non-invasive method was developed to exclude small intestine during conventional radiotherapy. materials and methods: the incidence of the radiation therapy interruption is highly dependent upon the area of the small intestine included in the portals and i...

BACKGROUND Interruption of enteral nutrition (EN) in the intensive care unit (ICU) occurs frequently for various reasons including feeding intolerance and the conduct of diagnostic and therapeutic procedures. However, few studies have investigated the details of EN interruption practices including reasons for and duration of interruptions. There is no standard protocol to minimize EN interrupti...

Deregulation of electricity market in the middle 90’s changed power distribution in Finland to more business oriented direction although the network business remained as regulated natural monopoly. According to the Electricity Market Act, the distribution companies have general obligations, e.g., to develop their electricity distribution networks and to have moderate distribution pricing. When ...
