Analyse de la genèse temporelle des trajectoires scolaires
1989
Analysis of the development of schooling routes in the course of time. - The authors present an empirical analysis of two fundamental questions in the field of knowledge and action : what are the respective parts : 1) of the primary and secondary school ; 2) of educational and institutional phenomena in the explanation of social differences of scolarity ? They conclude with a methodological thinking about the empirical analysis of educational phenomena which needs to take account of time.

Stone lines and heaps on south-western Niger plateaus as remains of ancient agricultural land
2011
Les plateaux de la rive occidentale du fleuve Niger sont recouverts de lignes et de tas de pierres sèches alors que ces surfaces tabulaires sont aujourd'hui dépourvues de toutes cultures. Le sol du plateau est constitué d'un horizon argilo-sableux visible uniquement dans la zone où ces structures sont présentes. Elles témoigneraient d'un épierrage pour faciliter le travail agricole du sol. Les matériaux extraits ont été disposés en ligne puis en tas si la quantité de blocs était trop élevée. Ce parcellaire pourrait être contemporain de l'activité métallurgique située au pied des plateaux et datée de la deuxième moitié du premier millénaire.
Régulation des systèmes éducatifs et réussite des élèves de 15 ans : analyse comparative dans les pays anglo-saxons avec PISA 2009
2013
Cette communication a également été présentée le 4 juin 2013 au CIQSS (Centre Interuniversitaire Québécois de Statistiques Sociales); Cette communication présente des résultats de comparaison internationale de la réussite des élèves de 15 ans, dans les pays anglo-saxons, et note l'effet des systèmes de régulation. Elle précise les analyses, notamment en observant les effets selon les niveaux des élèves en mathématiques et en sciences.
Incomplete retention of radiation damage in zircon from Sri Lanka
2004
A suite of 18 zircon gemstones from placers in the Highland/Southwestern Complex, Sri Lanka, were subjected to a comprehensive study of their radiation damages and ages. The investigation included X-ray diffraction, Raman and PL spectroscopy, electron microprobe, PIXE and HRTEM analysis, as well as (U-Th)/He and SHRIMP U-Th-Pb age determinations. Zircon samples described in this study are virtually homogeneous. They cover the range from slightly metamict to nearly amorphous. Generally concordant U-Th-Pb ages averaging 555 ± 11 Ma were obtained. Late Ordovician zircon (U-Th)/He ages scattering around 443 ± 9 Ma correspond reasonably well with previously determined biotite Rb-Sr ages for rock…
Wykorzystanie zasobów baz danych GIS na potrzeby analizy zróżnicowania obszarów wiejskich w aspekcie działań PROW = Application of GIS databases for …
2018
Realizacja działań w ramach Programu Rozwoju Obszarów Wiejskich (PROW) wymaga obiektywnego rozpoznania potrzeb ich wdrażania, w oparciu o wyniki analiz złożonych procesów przyrodniczych i ekono- miczno-demograficznych zachodzących w czasie i przestrzeni obszarów wiejskich. Wzrastająca funkcjonalność Systemów Informacji Geograficznej (GIS) oraz powszechna dostępność do informacji przestrzennej spowodowały, że bazy danych GIS i analizy geoprzestrzenne stały się skutecznym narzędziem wpierającym implementację działań PROW. Celem pracy jest przedstawienie możliwości wykorzystania danych geoinformacyjnych wybranych baz danych GIS do analizy zróżnicowania przestrzennego obszarów wiejskich wojewód…
Préparation et spéciation d’oxo-clusters de métaux du bloc p
2022
The main subject of this thesis is the use of Pair Distribution Function (PDF) analysis for solution phase speciation during metal-cluster growth. The PDF method allows the extraction of structural information from a sample in the form of an atom-atom distance distribution via Fourier transform of synchrotron X-ray scattering data. The growth mechanisms of two solution-based systems are analysed in this thesis. Precursor materials are synthesized through a mechanochemical method that was developed and shown to be able to access a wide range of related systems.Mechanochemical routes of synthesizing bismuth Active Pharmaceutical Ingredients (APIs) were investigated and optimised. Samples were…
Paleoecological insight into the straight-tusked elephant population from the late Middle Pleistocene site of Poggetti Vecchi
Il progetto di ricerca s’incentra sullo studio della macrofauna rinvenuta nel sito paleontologico e archeologico di Poggetti Vecchi, scoperto nella località di Roselle situata in provincia di Grosseto. Nello specifico esso è stato focalizzato sulla ricostruzione paleoambientale e paleoecologica dell’area. L’analisi paleobiologica e tafonomica dei resti faunistici è stata perciò inserita all’interno di un progetto multidisciplinare e l’integrazione di tutti i dati paleontologici (relativi a vertebrati, invertebrati, macroresti vegetali e pollini) con quelli stratigrafici ha permesso di ricostruire dettagliatamente l’evoluzione paleoambientale. Nella seconda parte, lo studio paleoecologico è …
Pårørendes erfaringer med bruk av frivillige ved alvorlig sykdom i hjemmet

Next-of-kins’ experiences when using volunteers for palliative patients living at home The aim of this study was to illuminate next-of-kins’ experiences when using volunteers supplementing community health care services for palliative patients living at home. The study has a qualitative approach. Nine individual interviews were conducted with next of kin from a municipality in Southern Norway. Use of volunteers for palliative care in the home was a relief for next-of-kin, especially prominent for families who had limited social network. Planned volunteering resulted in the best results. Use of volunteer was also found helpful for families as they were given a "breathing space" and a certain…
A molecular analysis of some Eastern Atlantic grouper from the Epinephelus and Mycteroperca genus
2005
Abstract Mitochondrial cytochrome b (397 bp) and 16S rDNA (516 bp) sequences analysis was used to investigate the phylogenetic relationships among some Eastern Atlantic Epinephelinae species. Six species of Epinephelus ( E. aeneus , E. caninus , E. costae , E. haifensis , E. marginatus and E. tauvina ) and two species of Mycteroperca ( M. rubra and M. fusca ) were analysed. Neighbour-joining and maximum-parsimony analysis support the paraphyletic grouping of the Epinephelus and Mycteroperca analysed. The maximum pairwise nucleotide divergence value in cyt b among all taxa was 0.196 between E. aeneus and E. marginatus and the minimum value was 0.006 between E. costae and M. rubra . Meanwhile…
