Income segregation in The Netherlands - trends and analysis

Dutch society does not accept high levels of income segregation. This tendency has repeatedly been revealed in public opinion surveys. Dutch government intervenes on different levels trying to mix low and high income groups both between cities and suburbs, as well as within city neighborhoods. The question is to what extent the assumptions on actual concentration and differentiation of different income groups hold true if compared to real figures. This paper publishes income data at 500 by 500 meter cells, showing significant spatial patterns of distribution and growth of low and high income groups. Remarkably, high income groups appear to be more segregated than low income groups. All Dutch central city areas have regained high income groups in the period 1995-2000, while the reverse happens in all other city neighborhoods. Despite those tendencies, large parts of the cities have a mixed composition of low, medium and high income groups.

AC field effect flow control of EOF in complex microfluidic systems with integrated electrodes

In this work, we demonstrate that positive net flow can be induced and controlled with relatively low potential due to the parallel alignment of the integrated channel electrodes. Therefore, we present a novel method to exquisitely control Electro Osmotic Flow (EOF) by using integrated electrodes fabricated beneath a meandering channel geometry (Figure 1). Equation 1 describes EOF velocity for AC-driven flow, where εo and εr respectively are the permittivity of vacuum and that of water, ζ the zeta potential at the solid liquid interface, η the viscosity, Ex the electric field

Modal Particles in Dutch as a Second Language. Evidence from a Perception Experiment

The perception of modal particles in Dutch was studied, contrasting native and speakers of Dutch as a second language (DSL). According to expectations, non-native subjects turned out to have more significant problems with selecting the best fitting stimulus in the contexts designed to evoke a modal use of the target word. Contrary to expectation, however, the non-native subjects had problems with non-modal contexts as well. Work on spontaneous speech elicited from DSL-speakers with Spanish as L1 revealed an unexpected but clear hierarchy in the acquisition of modal particles. The results are taken as an indication that Dutch particles, as well as their interaction with prosody, merit more attention in didactic materials aimed at DSL-speakers

Simulation of Micro-Electronic FlowFET Systems

A microelectronic fluidic system has been investigated by modeling and 3D simulation of fluid flow controlled by an applied gate voltage. The simulations have helped to characterize a novel FlowFET (a fluidic Field Effect Transistor) device under fault-free conditions. The FlowFET operates by applying a voltage field from a gate electrode in the insulated side wall of a microchannel to modulate the ␣-potential at the shear plane [1]. The change in ␣-potential can be used to control both the magnitude and direction of the electroosmotic flow in the microchannel

Lower risk of atopic disorders in whole cell pertussis-vaccinated children

This study addressed whether whole cell pertussis-vaccinated children have a different risk of atopic disorders compared with children who did not receive this vaccination. Data on vaccination status, atopic disorders and child and family characteristics of the children of 700 families were collected in this retrospective study. A minority of these 700 families refused vaccinations for religious reasons. The relation between pertussis-vaccination status and atopic disorders was analysed by means of adjusted logistic regression for repeated measurements in order to account for the correlation between sibship members. The 700 families included 1,961 children. Data on vaccination status and atopic disorders were available for 1,724 children. Vaccinated children had a reduced risk of atopic disorders. Whole cell pertussis vaccination is associated with a lower risk of atopic disorders, though other vaccine components (diphtheria, tetanus, poliomyelitis) or other vaccinations may also be involved

Molluscum contagiosum in Dutch general practice

BACKGROUND: While molluscum contagiosum is considered to be a frequently encountered disease, few data on its incidence are known. AIM: The objective of this study was to describe the incidence of molluscum contagiosum in Dutch general practice and to assess the importance of venereal molluscum contagiosum. METHOD: Data were taken from the national survey of morbidity and interventions in general practice, drawn from 103 practices across the Netherlands, with a study population of 332300. RESULTS: The infection appeared to be common in childhood (cumulative incidence 17% in those aged under 15 years); the adult, sexually transmitted, form was rare. Incidence was higher between January and June than between July and December. Cases were unequally divided between recording practices, which is though to have been caused by the occurrence of small epidemics. CONCLUSION: The incidence of molluscum contagiosum in Dutch general practice was found to be 2.4 per 1000 person years. Molluscum contagiosum should still be considered as a mainly paediatric disease
