‘Time’ in tourism: ‘individual time’ and ‘social time’ [PDF]

, 2009
The author does a review of the research into tourist activity and concludes that the particular character of tourist behaviour is reflected best in the study of time budgets. He proposes Max Weber's ideal-type method to be used in the analysis.

When honeybees come to town: Critical aspects of urban beekeeping and opportunities for regulation

People and Nature, EarlyView.
Abstract Urban areas are increasingly valued for their role in conserving wild pollinators. Honeybees are often regarded as ambassador species for pollinator conservation, and beekeeping is frequently perceived as a pro‐biodiversity activity, which has become highly popular in urban areas.

A VISUAL ANALYTICS OF MOVEMENT DATA OF A WASTE COLLECTION SERVICE: A TOOL FOR SMART CITIES [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Solid waste management is an important urban issue to be addressed in every city. In the smart city context, waste collection allows massive collection of data representing movements, provided by satellite tracking technologies and sensors on waste ...

High frequency wave packets for the Schr\"odinger equation and its numerical approximations [PDF]

, 2010
We build Gaussian wave packets for the linear Schr\"odinger equation and its finite difference space semi-discretization and illustrate the lack of uniform dispersive properties of the numerical solutions as established in Ignat, Zuazua, Numerical ...

Big Bird: A global dataset of birds in drone imagery annotated to species level

Remote Sensing in Ecology and Conservation, EarlyView.
Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

Amenable groups and measure concentration on spheres

, 1998
It is proved that a discrete group $G$ is amenable if and only if for every unitary representation of $G$ in an infinite-dimensional Hilbert space $\cal H$ the maximal uniform compactification of the unit sphere $\s_{\cal H}$ has a $G$-fixed point, that ...

Two loop and all loop finite 4-metrics [PDF]

, 1999
In pure Einstein theory, Ricci flat Lorentzian 4-metrics of Petrov types III or N have vanishing counter terms up to and including two loops. Moreover for pp-waves and type-N spacetimes of Kundt's class which admit a non-twisting, non expanding, null ...

Espaces odorants et espaces olfactifs

Journal of Interdisciplinary Methodologies and Issues in Sciences, 2023
Attester le partage d'une expérience olfactive par plusieurs individus est une gageure, du fait d'obstacles théoriques et méthodologiques souvent présentés comme irréductibles. Après une brève discussion de la réalité de cette irréductibilité, nous essayons de surmonter certains de ces obstacles en distinguant espaces odorants et espaces olfactifs.

Global determinants of home range sizes in felids: Evidence of human disturbance impact

Journal of Animal Ecology, EarlyView.
This study is the first to demonstrate the influence of anthropogenic factors and species richness in felids on home range size across the entire felid taxon. Felids are a taxon of major interest in conservation biology, and gaining a comprehensive view of their spatial ecology will help derive global conservation recommendations.

Botanical Fabrication: A research project at the intersection of design, botany and horticulture [PDF]

, 2015
‘Botanical Fabrication’ is an on-going research initiative which investigates how an understanding of botany and horticultural techniques can challenge the design process and lead to alternative sustainable manufacturing or ‘eco-facturing’ tools.
