The role of spatial epidemiology to support public health policies : case studies applied to health promotion, noncommunicable and infectious diseases in the canton of Vaud, Switzerland

Anaïs Laurence Ladoy

In a context of escalating public health challenges, including the rise of chronic diseases, the impact of climate change, and the COVID-19 pandemic, certain populations bear a disproportionate burden. As a result, there is an urgent need to develop public ...

Using machine learning to generate an open-access cropland map from satellite images time series in the Indian Himalayan region

Danya Li

Crop maps are crucial for agricultural monitoring and food management and can additionally support domain-specific applications, such as setting cold supply chain infrastructure in developing countries. Machine learning (ML) models, combined with freely-av ...

Metabolic influence of core ciliates within the rumen microbiome

Ianina Altshuler

Protozoa comprise a major fraction of the microbial biomass in the rumen microbiome, of which the entodiniomorphs (order: Entodiniomorphida) and holotrichs (order: Vestibuliferida) are consistently observed to be dominant across a diverse genetic and geogr ...

Planning: from model to modules

Florence Graezer Bideau

The tradition of planning in China is multisecular. The planning of the Chinese Imperial city was based on the model of the walled city that was reproduced and extended over several scales, from micro (courtyard) to macro (an entire city). The spatial revo ...

Geospatial digital monitoring of COVID-19 cases at high spatiotemporal resolution

Stéphane Joost, Idris Guessous, David Nicolas De Ridder

SARS-CoV-2 spreads via close contact during daily activities, forming clusters of cases mainly in households and workplaces. A crucial challenge to contain the spread lies in the early detection of these outbreak clusters, and the localisation and isolatio ...

Citizen Visual Search Engine: Detection and Curation of Urban Objects

Jeffrey Huang, Immanuel Chee Beng Koh

Increasingly, the ubiquity of satellite imagery has made the data analysis and machine learning of large geographical datasets one of the building blocks of visuospatial intelligence. It is the key to discover current (and predict future) cultural, social, ...

A temporal geography of encounters

João Vitor Meirelles de Miranda

Integrating social and spatial networks will be critical to new approaches to cities as systems of interaction. In this paper, we focus on the spatial and temporal conditions of encounters as a key condition for the formation of social networks. Drawing on ...

Spatial distribution of mammography adherence in a Swiss urban population and its association with socioeconomic status

Stéphane Joost, Idris Guessous

Purpose: Local physical and social environment has a defining influence on individual behaviour and health-related outcomes. However, it remains undetermined if its impact is independent of individual socioeconomic status. In this study, we evaluated the s ...

Delineating policies: governing spaces with no coextensive institutions : metropolitan areas and disadvantaged communities in the United States

Thomas Charles Marie Pierre Favre-Bulle

Many policies are spatially targeted: they attempt to foster or incent policy actions in areas meeting specific criteria. The identification and delineation of the spatial reality of interest is a major challenge to spatially targeted policies. In many cas ...

Penser (par) la carte : l'espace public et la marche à Mumbai et à Tokyo

Carole Thérèse Lanoix

What do Marine Drive and Shibuya have in common? Both the long promenade at the southern end of Mumbai, and the gigantic pedestrian crossing in the heart of the Japanese capital, are places where one walks. This thesis discusses places of convergence and o ...

Simple rules for an efficient use of Geographic Information Systems in molecular ecology

Stéphane Joost, Kevin Leempoel, Estelle Rochat, Solange Catherine Gaillard, Ivo Widmer

Geographic Information Systems (GIS) are becoming increasingly popular in the context of molecular ecology and conservation biology thanks to their display options efficiency, flexibility and management of geodata. Indeed, spatial data for wildlife and liv ...

Water use and quality in life cycle assessment : identifying good practices and developing operational spatial approaches

Anna Kounina Massé

Pressure on freshwater resources is increasingly covered by methodological developments addressing freshwater use in the field of Life Cycle Assessment (LCA). These developments ultimately lead to the publication of the ISO 14046 standard to define the pri ...

Adaptations to Climate-Mediated Selective Pressures in Sheep

Stéphane Joost, Sylvie Stucki

Following domestication, sheep (Ovis aries) have become essential farmed animals across the world through adaptation to a diverse range of environments and varied production systems. Climate-mediated selective pressure has shaped phenotypic variation and h ...

Algorithm for Flow Direction Enforcement Using Subgrid-Scale Stream Location Data

Producing realistic surface water flow patterns can be difficult for hydrologic models when there is insufficient grid resolution as a result of computational constraints or when available digital elevation model (DEM) data are relatively coarse. This tech ...

Statistical analysis of rainfall intermittency at small spatial and temporal scales

Alexis Berne, Marc Schleiss, Joël Jaffrain

Rainfall intermittency is analyzed and quantified at small spatial and temporal scales using 2 years of radar and disdrometer data collected in Switzerland. Analytical models are fitted and used to describe the intermittency for spatial scales between 0 an ...

La donnée géographique aux frontières des organisations : approche socio-cognitive et systémique de son appropriation

Geographic Information Technologies are now widespread. Geomatics tools are no longer restricted to a small number of technicians but impact on all of the actors within the land management sector (planners, geologists, foresters…). Many partnerships have e ...

Quantitative Geography and Genomics: Spatial analysis to detect signatures of selection along a gradient of altitude in the common frog (Rana temporaria)

Stéphane Joost

We applied a spatial approach to detect regions of the genome of the common frog (Rana temporaria) which are possibly selected along an altitude gradient. The identification of selected regions in the genome is important as it gives the possibility to unde ...
