Mensen in beweging: het gebruik van "tracking" gegevens binnen de ruimtelijke planvorming

In dit artikel wordt een kort overzicht gegeven van de verschillende activiteiten die binnen deze projecten plaatsvinden. Begonnen wordt met een korte uitleg van een aantal basisconcepten en vervolgens zal een casestudie rondom een toepassing voor het analyseren van recreatie in natuurgebieden worden gepresenteer

Simlandscape: serious gaming in participatory spatial

In an attempt to improve support for contemporary spatial planning practice, Simlandscape has been developed. In this document the development of Simlandscape as ¿serious game¿ in digital form is described. In its current state, Simlandscape exists in two methodological forms; as an analogue game and as a planning support system using GIS for research and design. The game focuses on simulation of plan processes and on the resulting transformation of areas involved. Players interact with an analogue area model. The planning support system focuses on design and evaluation of plan scenarios and the data handling and presentation accompanying this process. A major challenge now is to integrate, upgrade and digitize components of the analogous game with the planning support system. Several interesting components (practical and scientific) of this project are identified and are discussed

An agent-based approach to model land-use change at a regional scale

Land-use/cover change (LUCC) is a complex process that includes actors and factors at different social and spatial levels. A common approach to analyse and simulate LUCC as the result of individual decisions is agent-based modelling (ABM). However, ABM is often applied to simulate processes at local scales, while its application in regional studies is limited. This paper describes first a conceptual framework for ABM to analyse and explore regional LUCC processes. Second, the conceptual framework is represented by combining different concepts including agent typologies, farm trajectories and probabilistic decision-making processes. Finally, the framework is illustrated through a case study in the Netherlands, where processes of farm cessation, farm expansion and farm diversification are shaping the structure of the landscape. The framework is a generic, straightforward approach to analyse and explore regional LUCC with an explicit link to empirical approaches for parameterization of AB

De digitale wichelroede en haar gebruikers : interactieve location based services voor cultuur-historische landschapsbeleving

Project de Digitale Wichelroede onderzoekt hoe op innovatieve wijze cultuurhistorische kennis beschikbaar gemaakt kan worden via een PDA met GPS en UMTS-transmissie voor de wandelaar of fietser die zijn omgeving fysiek en virtueel wil beleven, en via de Volksmondfunctie op interactieve wijze informatie kan toevoegen. Circa 70% van de deelnemers oordeelt positief over de Digitale Wichelroede. De belangrijkste conclusie is dat een wandel- of fietstocht met de digitale wichelroede een meerwaarde bevat ten opzichte van een “gewone” wandel- of fietstoch

Predictors of renal flares and long-term renal outcome in patients with lupus nephritis:results from daily clinical practice

OBJECTIVES: To describe renal outcomes of the lupus nephritis (LN) population of the University Medical Centre Groningen (UMCG) in the Netherlands and to identify predictors for renal flares and long-term renal outcome in daily clinical practice. METHODS: A retrospective analysis of biopsy-proven LN patients with induction and maintenance treatment in the UMCG between 1982 and 2016 was performed. Data were collected at time of diagnosis, after 6 months and every year up to 10 years after diagnosis. Outcome measures were renal relapse (biopsy proven), progression to chronic kidney disease (CKD) stage 3 or 4 and chronic renal replacement therapy. The ability of serum creatinine, proteinuria, creatinine clearance, serum anti-double stranded DNA (anti-dsDNA) antibodies, serum complement 3 (C3) and serum complement 4 (C4), as well as biographic data and histopathological class to predict long-term renal outcome was assessed. RESULTS: Seventy-one patients were included, with median follow-up of 120 months (IQR 48-120 months). During follow-up - up to 10 years - twenty-one (30%) patients experienced at least one relapse. Eleven (15%) patients had CKD stage 3 or 4, of whom eight showed persistent CKD since baseline and two (3%) patients required chronic renal replacement therapy. At baseline, low levels of serum C3 were a significant predictor of renal relapse. Low levels of C3 and C4 at 6 and 12 and proteinuria and high levels of anti-dsDNA at 12 months were significant predictors of renal relapse. At baseline, 6 months and 12 months serum creatinine and creatinine clearance were significant predictors for persistent or newly developed CKD 3 or 4, and need for chronic renal replacement therapy. CONCLUSIONS: Almost one-third of LN patients experience at least one renal relapse during long-term follow up, but only 3% need chronic renal replacement therapy. Our data suggests that early serological remission is associated with a low risk of renal relapse. Decreased renal function at onset and the first year after diagnosis is predictive for decreased renal function at a later stage
