BACKGROUND The achievement of dialysis adequacy targets in peritoneal dialysis (PD) is assessed by the calculation of the Kt/V and creatinine clearance (C(Cr)) obtained by collecting dialysate and urine, usually two or three times a year. Prescription decisions are based on such adequacy assessments, regardless of any variability in the single measurements. The aim of our study was to assess th...

The effects of driver experience delay on the dynamics of a nonlinear day-to-day traffic model are investigated. When parameters are varied oscillations may arise via flip and Neimark-Sacker bifurcations in the non-delayed and delayed cases, respectively. The nonlinear behavior is analyzed using normal form calculations which are validated by numerical continuation and simulation. It is shown t...

In medicine, it is the physician's obligation to promote and protect the patient's interest. In obstetrics, the ethical principles of beneficence and autonomy provide the fundamental framework which guides the management of all pregnant patients. As there is the need for consideration of the fetus, autonomy can become a complex issue giving rise to what is sometimes called "maternal-fetal confl...

Using examples of incidents that UK Police Forces deal with on a day-to-day basis, we explore the macrocognition of incident response. Central to our analysis is the idea that information relating to an incident is translated from negotiated to structured and actionable meaning, in terms of the Community of Practice of the personnel involved in incident response. Through participant observation...

Bailey, D.W., Walker, J.W. and Rittenhouse, L.R., 1990. Sequential analysis of cattle location: day-to-day movement patterns. Appl. Anita. Behav. Sci., 25: 137-148. Studies were conducted in Texas and Colorado to determine if there were consistent movement patterns of grazing cattle. Based on optimal foraging theory, we hypothesized that cattle would select the same area of a pasture to graze f...

In this paper we propose a “prediction-correction” framework to model traveler’s perception evolution under network disruption. Distinctive from existing models, the proposed framework assumes drivers make their trip choices according to their predictions on future traffic, since previous daily experiences become invalid when network is disrupted. Drivers predict travel costs after network disr...
