Les puits de l’oppidum de l’Ermitage (Agen, Lot-et-Garonne).
2007
Within the context of a “projet collectif de recherche”, the publication of works directed by Richard Boudet on the hillfort of the Ermitage in Agen, two wells have been studied. The analysis of structures and artefacts (pottery, metal, wood) suggests that they were probably used to draw water and not devoted to chthonian rituals. Comparisons with other wells un South West of Gaul suggest that in most cases, they may have been used in the same way, even though, in very few cases rituals relating to the domestic field cannot be excluded.
Les débats devant la commission d'esclavage
2010
On March 4, 1848, thanks to the decisive impetus given by Victor Schoelcher, the principle of the abolition of slavery was proclaimed by decree and a « Commission for the preparation of an act of immediate emancipation in all the colonies of the Republic » was established. Like the commission de Broglie under the July Monarchy, the commission, chaired by Schoelcher, provided a huge work of documentation, information and reflection on the settlements, studying also the organization of the English colonies. However, unlike the previous one, the commission of 1848 required the immediate abolition of slavery (Decree of April 27, 1848), without waiting for the election of the National Assembly, …
CLUSTERING INCOMPLETE SPECTRAL DATA WITH ROBUST METHODS
2018
Abstract. Missing value imputation is a common approach for preprocessing incomplete data sets. In case of data clustering, imputation methods may cause unexpected bias because they may change the underlying structure of the data. In order to avoid prior imputation of missing values the computational operations must be projected on the available data values. In this paper, we apply a robust nan-K-spatmed algorithm to the clustering problem on hyperspectral image data. Robust statistics, such as multivariate medians, are more insensitive to outliers than classical statistics relying on the Gaussian assumptions. They are, however, computationally more intractable due to the lack of closed-for…
A Combined Multi-Cohort Approach Reveals Novel and Known Genome-Wide Selection Signatures for Wool Traits in Merino and Merino-Derived Sheep Breeds.
2019
Merino sheep represents a valuable genetic resource worldwide. In this study, we investigated selection signatures in Merino (and Merino-derived) sheep breeds using genome-wide SNP data and two different approaches: a classical F-ST-outlier method and an approach based on the analysis of local ancestry in admixed populations. In order to capture the most reliable signals, we adopted a combined, multi-cohort approach. In particular, scenarios involving four Merino breeds (Spanish Merino, Australian Merino, Chinese Merino, and Sopravissana) were tested via the local ancestry approach, while nine pair-wise breed comparisons contrasting the above breeds, as well as the Gentile di Puglia breed, …

Siinä pitää kyllä olla vähä teflonii : tunnekokemuksia johtajana irtisanomistilanteessa
2017
The world of leadership has often been considered a callous world characterized at best only by masculine feelings, such as aggressiveness. In addition, leadership has traditionally been considered an influential skill of individuals. In this study, leadership was examined as a socially constructed phenomenon that develops as a result of interaction between leaders and their subordinates and that cannot be separated from the framework in which it takes place. The target phenomena in the present study were leaders’ emotional experiences related to those who were being dismissed. The main research task was to conduct an empirical study on leaders’ experiences as parties giving notices and ana…

Lierojen parittelumenestyksen yhteys sää- ja ympäristöoloihin, yksilötiheyteen ja yksilön kokoon
2011
Yksilön kelpoisuus riippuu jälkeläistuotosta, ja parittelumenestys on yksi jälkeläistuoton avaintekijöistä. Monien eläinlajiryhmien lisääntymistä on tutkittu laajasti sekä laboratorio-oloissa että luonnossa, mutta lierojen lisääntymismenestykseen vaikuttavia tekijöitä luonnonpopulaatioissa ei vielä juurikaan tunneta. Tämän tutkimuksen tavoitteena oli selvittää, miten kahden ekologialtaan erilaisen lierolajin parittelumenestys riippuu ympäristöoloista, yksilötiheydestä ja yksilön koosta. Tutkimuksessa käytettiin tietoja lieronäytteistä, jotka oli kerätty syksyinä 2004 ja 2005 viljelymailta eri puolilta Suomea. Spermatoforien esiintymistä yksilöillä käytettiin indikaattorina näytteenottoa ede…
Genetic diversity of a clonal earthworm : gene expression variation and impacts on decomposition in metal contaminated soil
2016
Biodiversity affects ecosystem functioning positively. Metal-contamination diminishes species diversity and ecosystem function depends on the remaining species, and the genotypes within them. I studied how the clonally reproducing earthworm Dendrobaena octaedra responds to soil metal contamination and how its genetic diversity affects decomposition. Expression of the gene for the metal tolerance protein metallothionein was compared between populations with or without metal exposure history: with exposure history expression was high and stable and without there was a slow response. Adaptation to metal contamination likely explains the differences. Clonality of D. octaedra was verified with m…
