Stageberichten

Als bestuurskunde-student ben je voor je stage niet gebonden aan de overheid, maar kun je ook in de private sector terecht. Zo loopt Nery Duivenvoorden momenteel stage bij de NMB Postbank Groep. Ze is inmiddels vijfdejaars en koos indertijd voor de studie bestuurskunde, omdat de interdisciplinaire benadering haar erg aansprak. Via bekenden kwam Nery aan deze interessante stageplaats. Vanuit Bloomington in de USA schreef ze een brief en terug in Nederland kon ze 1 september 1991 direct aan de slag

Room for the River: a stepping stone in Adaptive Delta Management

This paper explores how the Room for the River Program contributes to the introductionof adaptive delta management (ADM) as applied by the Delta Program in The Netherlands.The concept of Room for the River is based on a holistic, integrated approach embracing amulti-functional river in which flood safety is realized in combination with other values suchas landscape, environmental and cultural values. This new approach acknowledges the need forlearning (which is a key feature of adaptive management) and more flexibility to deal with anuncertain future as river widening inherently provides future flexibility. On the basis of the resultspresented in this paper it is argued that Room for the River can be considered a stepping stonein ADM of the Delta Program as it has become the new standard for flood risk management inthe Netherlands to take a system approach, embrace experimentation and learning and involvemultiple stakeholders. Within the development and implementation of Room for the River theseenabling elements, have influenced and shaped the institutional processes and practices on whichthe Delta Program is founded and of which new concepts and approaches could emerge (such asmulti-layer safety, adaptation pathways). This evolutionary process of strategy development hasresulted in the following unique features of ADM of the Delta Program: 1) short term actions arelinked to long term goals; 2) flexibility is valued and incorporated in strategic policy-making; 3)multiple strategies are considered in a rational manner (adaptive pathways); and 4) different investment agendas are inter-linked. These features may also provide guidance for other countriesthat are attempting to reform their flood risk management strategies

Naar een nieuw politiebestel

Na vele jaren van discussie over de slecht functionerende Nederlandse politie is men nu zover dat er daadwerkelijk iets gaat veranderen. Eén van de grootschaligste en meest complexe reorganisaties in de ambtelijke wereld is zich momenteel aan het voltrekken: het samengaan van Rijks- en Gemeentepolitie tot een regionaal georganiseerde politie. Om een goed inzicht te krijgen in deze reorganisatie hebben wij iemand geïnterviewd die er midden in zit, dhr. Poeiert, ex-commissaris van de Gemeentepolitie Leiden en na de reorganisatie plaatsvervangend hoofd van de regio Hollands-Midden, waar Leiden ook deel van uit gaat maken

Direct observation of charge inversion by multivalent ions as a universal electrostatic phenomenon

We have directly observed reversal of the polarity of charged surfaces in water upon the addition of tri- and quadrivalent ions using atomic force microscopy. The bulk concentration of multivalent ions at which charge inversion reversibly occurs depends only very weakly on the chemical composition, surface structure, size and lipophilicity of the ions, but is dominated by their valence. These results support the theoretical proposal that spatial correlations between ions are the driving mechanism behind charge inversion.Comment: submitted to PRL, 26-04-2004 Changed the presentation of the theory at the end of the paper. Changed small error in estimate of prefactor ("w" in first version) of equation

The perception of the vertical dimension (3D) through the lens of different stakeholders in the property market of China

China has experienced fast urbanization with a growing urban population, which has inevitably led to the adoption of a vertical housing style with high-rise buildings. However, how people subjectively perceive the vertical dimension (3D) in the property market is neither adequately documented nor well understood. The 3D perception helps us to understand a myriad of social and psychological effects of living in high-rise buildings. We organized and conducted semi-structured expert interviews, focus groups, and the circulation and compilation of questionnaires in Xi’an, China, to investigate how different stakeholders in the property market perceive 3D. The results show that: (1) real estate developers do not adjust property prices for specific 3D factors, and the local government does not consider 3D in housing policies; (2) the current status of 3D modeling in Xi’an is still in the embryonic state; (3) 3D factors are highly valued by buyers but not well-understood by real estate developers and local government. In addition, 3D factors score higher than horizontal (2D) factors (1.12 to 0.88). Gender and age groups do not influence housing preferences concerning 2D and 3D factors. These findings provide valuable insights for real estate developers concerning pricing policies and the local government concerning housing policies. In the future, 3D perceptions and factors should be prioritized in order to improve urban infrastructure and ensure the increased availability of, and fair public access to welfare related to 3D in urban areas
