Clinical use of electrical stimulation with the Veinplicity device and its effect on the first attempt success rate of peripheral intravenous cannulation: A non-randomized clinical trial.

Background: Peripheral intravenous cannulation is one of the most frequently performed medical procedures. Venodilation, which can be achieved with different techniques, is an important factor for first attempt success. The objective of this study was to compare the first attempt success rates upon peripheral intravenous cannulation after applying a tourniquet, with venous dilation by electrical stimulation using the Veinplicity device, or a combination of both techniques, in participants at moderate risk of a difficult peripheral intravenous access.

Modelling and simulating decision processes of linked lives: An approach based on concurrent processes and stochastic race.

Individuals' decision processes play a central role in understanding modern migration phenomena and other demographic processes. Their integration into agent-based computational demography depends largely on suitable support by a modelling language. We are developing the Modelling Language for Linked Lives (ML3) to describe the diverse decision processes of linked lives succinctly in continuous time.

Multistate modelling extended by behavioural rules: An application to migration.

We propose to extend demographic multistate models by adding a behavioural element: behavioural rules explain intentions and thus transitions. Our framework is inspired by the Theory of Planned Behaviour. We exemplify our approach with a model of migration from Senegal to France.

Emigration Rates From Sample Surveys: An Application to Senegal.

What is the emigration rate of a country, and how reliable is that figure? Answering these questions is not at all straightforward. Most data on international migration are census data on foreign-born population. These migrant stock data describe the immigrant population in destination countries but offer limited information on the rate at which people leave their country of origin.
