Remote sensing green-up date from SPOT-VEGETATION data at Daring Lake (1998-2012), link to GeoTIFF
No full textOne of the reported changes in arctic and boreal ecosystems in response to warming climate is the advance of the leaf and flower appearance in spring. We developed a remote sensing (RS) method, using 1km spatial resolution SPOT-VGT sensor, to estimate the date of boreal ecosystem green-up without detrimental effect of snow on the signal.
The tif file is made of 15 images, one for each year from 1998 to 2012. The pixel value gives the date at which the ecosystem starts green-up (expressed as the day of year) as estimated in Delbart et al. 2005

New Necklaces: 400 Designs in Contemporary Jewellery
No full textAfter the successful New Rings and New Earrings, New Necklaces is the third book curated by jeweller and author Nicolas Estrada, from classic forms and materials to the most daring, experimental and surprising ideas, each of the 500 necklaces included in this book has something that makes it unique and relates strongly to today's social, cultural and artistic reality. With prefaces by German jeweller Julia Wild and Leo Caballero, owner of the Barcelona gallery Klimt 02, specialised in contemporary jewellers
How Did I Get to Princess Margaret? (And How Did I Get Her to the World Wide Web?)
No full textThe paper explores the growing use of
tools from the arts and humanities for investigation
and dissemination of social science research.
Emerging spaces for knowledge transfer, such as
the World Wide Web, are explored as outlets for
"performative social science". Questions of ethnics
and questions of evaluation which emerge from
performative social science and the use of new
technologies are discussed. Contemporary thinking
in aesthetics is explored to answer questions
of evaluation. The use of the Internet for productions
is proposed as supporting the collective
elaboration of meaning supported by Relational
Aesthetics.
One solution to the ethical problem of performing
the narrations of others is the use of the writer's
own story as autoethnography. The author queries
autoethnography's tendency to tell "sad" stories and
proposes an amusing story, exemplified by "The
One about Princess Margaret" (see Appendix).
The conclusion is reached that the free and open
environment of the Internet sidelines the usual
tediousness of academic publishing and begins to
explore new answers to questions posed about
the evaluation and ethics of performative social
science
Identification of author profiles through social networks
No full textThe aim of this paper is to compile dictionaries of slang words, abbreviations, contractions, and emoticons to help the pre-processing of texts published in social networks. The use of these dictionaries is intended to improve the results of the tasks related to data obtained from these platforms. Therefore, a hypothesis was evaluated in the task of identifying author profiles (author profiling).Silva, JesúsMaria Santodomingo, Nicolas EliasRomero, LigiaJorge, MarisolHerrera, MaritzaPineda Lezama, Omar Bonerg
Spring Phenology of the Boreal Ecosystems
No full textInternational audienceEcosystem phenology, i.e. the timing of key biological events, is often considered as both a witness and an actor of climate change. Phenological interannual variations and decadal changes reflect climate variability and trends. Deciduous plant phenology also directly influences the carbon, water and energy exchanges of the ecosystem with the atmosphere. In the northern forests, a trend to earlier spring has been widely reported, often based on remote sensing methods. This trend is suggested to explain a part of the residual carbon sink. However methodological issues, especially related to the combined effects of the vegetation and of the snow cover seasonal changes on the remote sensing signal, were found to affect the results. This chapter describes a remote sensing green-up retrieval method designed to avoid signal contamination by snow. The result validation with ground observations showed that the method catches the interannual variations in phenology of the plant community. Changes in the 1998-2017 are analyzed and positioned in a longer term. This shows that the most persistent feature over the last decades is a large-scale shift in the green-up date at the end of the 1980's, and that the green-up date has not recovered yet to its status prior to 1987. Finally the green-up date maps were used to represent phenology in the northern ecosystem carbon budget simulations. No unidirectional effect of phenological changes in the annual carbon balance could be identified because of a complex interplay between vegetation, water resources and climate
