1. The uptake of bilirubin was studied in the perfused rat liver by a multiple-indicator dilution technique employing the three-compartment model of Goresky. 2. The kinetics of hepatic bilirubin uptake could be described by the Michaelis-Menten equation. 3. The maximal uptake velocity (V max.) and the apparent half-saturation constant (Km) were 4-4 +/- 0-5 nmol s-1 g-1 of liver and 58 +/- 16 nm...

ing the World As already mentioned, the WorldMarket of the agent-based model is actually a portal to an LCI database. This integration means that we can simulate a system in which we have a “lens” of complex dynamic behavior where agents interact with a static definition of the world.

Joining the debate on the structure of depression, S. R. H. Beach and N. Amir (2003) analyzed college students’ responses to 6 Beck Depression Inventory (BDI) items with predominantly somatic content and concluded that they identified a small latent taxon corresponding to involuntary defeat syndrome. An exact replication of these analyses yielded virtually identical taxometric results, but para...

When scientometricians are asked about the relationship between citations and quality, they often argue along the lines that citations could be seen as indicators of use and that that this implies usefulness and impact on other research, which in turn is an argument for using them as indicators of quality. This paper questions the implicit linearity of such a ‘one-dimensional model’ of represen...

Although the motivating role of feedback and progress indicators is understood in formal learning, their role in supporting incidental mobile learning is less well understood. In this paper we argue that well-designed feedback and progress indicators (FPIs) offer guidance and structure that may encourage mobile app users to move from fragmented learning episodes towards a longer term, reflectiv...

We advance scholarship about how macroeconomic forces differentially manifest themselves across local spaces by developing a holistic conceptual framework and empirical analyses involving multilevel change modeling. Unlike prior work, we examine differential rates of change in neighborhood indicators. We illustrate our approach with Chicago data measuring the crime, housing, and economic domain...

An orientation experiment was carried out in a spatially immersive virtual environment. The task of subjects was to navigate with 6 degrees of freedom flying method through a predefined route guided by visual cues. Simultaneously they should keep the model oriented in upright position as well as possible. In the experiment we had three different implementations of auditory artificial horizon, a...

For user-friendliness purposes, many modern software systems provide progress indicators for longrunning tasks. These progress indicators continuously estimate the percentage of the task that has been completed and when the task will finish. However, none of the existing program compilation tools provide a non-trivial progress indicator, although it often takes minutes or hours to build a large...
