Standardization proposal for the mapping of Caulerpa taxifolia expansion in the Mediterranean sea

1999

Fourteen years after the first observation of Caulerpa taxifolia (Valh) C. Agardh in the northwestern Mediterranean Sea, this green alga of tropical origin is now present in five countries (Spain, France, Monaco, Italy and Croatia). By the end of 1997, more than 46 km(2), at depths of between 0 and 50 m, were found to be affected by this expansion. A standardization of the cartographic procedure is proposed here. Such a standardization is necessary to compare maps produced by various organizations from different countries. For a given independent station, it is based on the definition of three levels of colonization:Level I refers to a station where one or several colonies less than 100 m a…

Statistical modelling and RCS detrending methods provide similar estimates of long-term trend in radial growth of common beech in north-eastern France

2011

International audience; Dendrochronological methods have greatly contributed to the documentation of past long-term trends in forest growth. These methods primarily focus on the high-frequency signals of tree ring chronologies. They require the removal of the ageing trend in tree growth, known as 'standardisation' or 'detrending', as a prerequisite to the estimation of such trends. Because the approach is sequential, it may however absorb part of the low-frequency historical signal. In this study, we investigate the effect of a sequential and a simultaneous estimation of the ageing trend on the chronology of growth. We formerly developed a method to estimate historical changes in growth, in…

Is «Social language variation» an operational category for language corpus planning?

2019

Hem constatat les dificultats d’aprofundir les relacions conceptuals entre la variació social i la funcional, que comencen quan ens preguntem quins factors socials són pertinents per descriure el col·loquial. Creiem que cal tenir en compte, en ordre decreixent, les «adscripcions identitàries» que Block (2014) analitza: capital lingüístic, capital cultural, edat, gènere, activitat habitual, «habitus/ideologia/actituds», «classe social», ètnia i religió. En aquest context d’incertesa conceptual, no és estrany que la variació social sigui una dimensió sociolingüística tractada inadequadament en la normativa catalana: Badia (1994) confon els termes diastràtic i diafàsic i llegint els textos nor…

Normalisation et individualisation de l’équipement du guerrier à l’âge du Bronze (XVIe–IXe siècle av. J.-C.) : le cas des épées et de l'armement …

2019

International audience; L'étude de la forme et de l'ornementation de l’armement offensif et défensif de l'âge du Bronze indique une standardisation des productions suivant des traditions qui varient selon la région et la période considérées. L’homogénéité de ces objets au sein d'un espace témoigne de l’adhésion, consciente ou non, des utilisateurs de ces objets à une communauté partageant une même norme et identifiable par la possession d’objets à l’identité visuelle commune, qui dépasse parfois le cadre de l’armement. Ces caractères standardisés devaient ainsi constituer une composante culturelle forte, certains utilisateurs n'hésitant pas à modifier des pièces importées afin de les adapte…

European Sero-Epidemiology Network 2: standardisation of immunoassay results for pertussis requires homogeneity in the antigenic preparations.

2008

A standardisation process, already developed during the earlier European Sero-Epidemiology Network (ESEN) project, was employed with a more robust algorithm to harmonise results of pertussis serological assays performed in 12 European and non-European countries. Initially, results from each country's own assay were compared with those obtained at the reference laboratory by means of an in-house pertussis toxin (PT)-based ELISA: seven countries used in-house or commercial PT-ELISAs; the other countries used assays based on Bordetella pertussis whole cell extracts (WCE) (three countries) or on combined PT-FHA (filamentous haemagglutinin) antigenic preparations (two countries). The WCE assays,…

Measuring basal soil respiration across Europe: Do incubation temperature and incubation period matter?

2014

The European Commission recognises the essential role of soil biology in soil functioning and delivery of ecosystem services, but information is currently lacking evaluate of how these vary across soil and land-use types at a European scale. This study evaluated the measurement of the initial rate of soil basal respiration (BR) as a potential biological indicator of ecosystem service provision. The purpose of this study was to test ISO 16072:2002 (Soil Quality: Laboratory methods for the determining of microbial soil respiration). In the literature a range of pre-incubation temperatures (pre-inc) and experimental incubation temperatures (exp-inc) have been applied when using the ISO method …

Project report : Lessons learned from terminology harmonisation

2022

A common understanding of language and the meaning of concepts is needed for communications in general, and can be crucial to save lives in large rescue operations. Redningshåndboka (the National Rescue handbook) provides a common glossary for first responders’ communications across all sectors in training and practice. However, today each sector maintains their own glossaries, acronyms and jargon, causing potential misunderstandings in joint operations. In this report we outline lessons learned from national and international standardisation and additional practical project outcomes to contribute to terminology harmonisation from the INSITU project.

Imaging standardisation in metastatic colorectal cancer: a joint EORTC-ESOI-ESGAR expert consensus recommendation

2022

Background: Treatment monitoring in metastatic colorectal cancer (mCRC) relies on imaging to evaluate the tumor burden. Response Evaluation Criteria in Solid Tumors (RECIST) provide a framework on reporting and interpretation of imaging findings yet offer no guidance on a standardized imaging protocol tailored to mCRC patients. Imaging protocol heterogeneity remains a challenge for the reproducibility of conventional imaging endpoints and is an obstacle for research on novel imaging endpoints. Patients and methods: Acknowledging the recently highlighted potential of radiomics and artificial intelligence (AI) tools as decision support for patient care in mCRC, a multidisciplinary, internatio…
