Quadtrees Hub#5

Portraying Urban Sprawl from Space: an update and geographical effects On March 10th (NEW DATE), our fifth Quadtrees Hub will take place. The aim is to share and discuss research in progress. Quadtrees’hubs are open to anyone interested and somehow familiar with some quantitative techniques and willing to progress with these. Please contact Isabelle Pigeron-Piroth

Activity spaces in place and health research: Novel exposure measures, data collection tools, and designs

So excited to see our paper on “Activity spaces in place and health research” published in Health and Place, with Basile Chaix and Yan Kestens : https://doi.org/10.1016/j.healthplace.2019.05.008 Free access until October 9th, 2019: https://authors.elsevier.com/a/1ZbT5_Uo5A~6R5  Our commentary answers a systematic review from Lindsey Smith, Louise Foley and Jenna Panther on “Activity spaces in studies of the environment

When motility and movement meet wellbeing

Check out our new CURHA (Contrasting Urban Environments and Healthy Ageing, FNR-IRSC-FRSQ project) paper on links between mobility and wellbeing among older adults in Luxembourg ! We used the concept of motility, estimated in a structural equation model, in order to disentangle the complex relationships between locations, geographic environments and daily mobility related to wellbeing.

Is older adults’ physical activity during transport compensated during other activities?

Check out our new CURHA paper, led by Dr. Ruben Brondeel, and comparing 4 study cohorts using GPS and accelerometers !  https://www.sciencedirect.com/science/article/pii/S2214140518305048 Abstract Introduction Promoting active transport offers the potential to increase population physical activity levels. Compensation theories state that above-average physical activity in one activity is compensated in later activities; a mechanism that results

For policy-relevant measures, it is important that policymakers are able to foresee how quality improvements influence the price of land, over time and space.

Abstract Urban development projects have many effects on society, such as improving mobility, health, education, and sustainability. For policy-relevant measures, it is important that policymakers are able to foresee how quality improvements influence the price of land. Therefore, our objective is to collect a set of variables able to account for the effects of a multitude of land

Dis-equalising impact of Housing

https://www.sciencedirect.com/science/article/pii/S1051137718301293 The measure of a household’s income should include not only monetary components such as job salary but also non-monetary components and in-kind benefits, such as imputed rent. Imputed rent is the rent an owner can expect to receive were the house on the rental market. Being an owner-occupier does not provide a rental income

Now there is a formal link between standard intra-urban theory of residential choice and population scaling as of urban systems theory! A must read in Geographical Analysis

Justin Delloye, Rémi Lemoy (now at UMR Idées, Rouen) and Geoffrey Caruso just published an article where they reconcile Alonso and the scaling literature. This is done through an augmented micro-economic model where scaling exponents are explicit and the scaling with population of the profile of residential land is exogenously given to better suit empirical

The land transformation model-cluster framework: Applying k-means and the Spark computing environment for large scale land change analytics

Omrani H., has a new article published in the EMS journal.  The paper explores the challenges of simulating land change across large regions and spans of time.  The new mode, called LTM-Cluster,  is a scalable modeling framework aimed to benefit research involving large datasets. The paper uses the Spark environment to reduce the burden of high computational
