BACKGROUND Responsiveness is an indicator by WHO to evaluate the performance of health systems on nonmedical expectations of consumers. This study measures the health system responsiveness and the factors affecting responsiveness in Iran health system. METHODS World Health Survey (WHS) questionnaire was used to collect data on a two-stage cluster sampling in 17th District of Tehran in 2003. O...

It is well known that TCP does not fully utilize the available bandwidth in fast long-distance networks. To solve this scalability problem, several high speed transport protocols have been proposed. They include HighSpeed TCP (HS-TCP), Scalable TCP (S-TCP), Binary increase control TCP (BIC-TCP), and H-TCP. These protocols increase (decrease) their window size more aggressively (slowly) compared...

We present an integrated approach for real-time performance prediction of volume raycasting that we employ for load balancing and sampling resolution tuning. In volume rendering, the usage of acceleration techniques such as empty space skipping and early ray termination, among others, can cause significant variations in rendering performance when users adjust the camera configuration or transfe...

This paper proposes a bi-objective reliable supply chain network design that immunizes the network against different sources of uncertainties. In this regard, scenario based stochastic programming method is applied to model different disruption scenarios affecting accurate performance of network stages. Also, reliable and unreliable facilities are suggested for lessening vulnerability of networ...

• Marketing skills and market responsiveness are vital for emerging exporting firms operating in advanced markets. Market mediates the influence of marketing on performance. The mediating is positively moderated by competitive intensity Emerging economies must manage a highly dynamic landscape owing to factors such as changing needs fierce competition. Hence, these need develop unique superior ...

BACKGROUND Responsiveness refers to a measurement tool's ability to detect change in performance over time. The aim of the review was to summarise studies of responsiveness of lower limb physical performance measures during inpatient care after stroke. METHODS A systematic literature review was conducted. Prospective studies that included participants with a diagnosis of stroke, were commence...

BACKGROUND Health systems increasingly try to make their services more responsive to users' expectations. In the context of the World Health Report 2000, WHO developed the concept of health system responsiveness as a performance parameter. Responsiveness relates to the system's ability to respond to service users' legitimate expectations of non-medical aspects. We used this concept in an effort...

UNLABELLED In studies of cognitive processing using tasks with externally directed attention, regions showing increased (external-task-positive) and decreased or "negative" [default-mode network (DMN)] fMRI responses during task performance are dynamically responsive to increasing task difficulty. Responsiveness (modulation of fMRI signal by increasing load) has been linked directly to successf...
