La régulation managériale et des équipes en contexte multiculturel : le cas d’un hypermarché en Nouvelle-Calédonie
No full textInternational audienceThe purpose of this study is to understand regulation within multicultural teams in the context of training development aimed at improving customer relations. The study, which resembles a case study, takes place within a hypermarket located in New Caledonia. Data collection involved observing exchanges during training sessions and conducting exploratory interviews. One year after the training, targeted interviews were conducted with cashiers to assess the training's benefits. Our results show that it is challenging for cashiers to envision themselves in an organization where the cultural dimension is nearly absent, and where contracts and rules are the sole foundations. Training has had unexpected effects on regulation. This study opens research perspectives on the analysis of the applicability of management practices in New Caledonia to other multicultural environments. Conducting longitudinal studies to examine group dynamics and employee adaptation to imposed regulations is also suggested.L’objet de l’étude est d’appréhender la régulation au sein des équipes multiculturelles dans un contexte de développement de la formation dans le but d’améliorer la relation client. L’étude, qui s’apparente à une étude de cas, se déroule au sein d’un hypermarché situé sur le territoire de la Nouvelle-Calédonie. Le recueil des données a consisté à observer les échanges lors de séances de formation et à mener des entretiens exploratoires. Une année après la formation, des entretiens ciblés ont été réalisés avec les caissières pour évaluer les apports de la formation. Nos résultats montrent qu’il est difficile pour les caissières de se projeter dans une organisation dans laquelle la dimension culturelle est quasi absente et pour laquelle le contrat et la règle sont les seules fondations. La formation a eu des effets inattendus sur la régulation. Cette étude ouvre des perspectives de recherche sur l’analyse de l’applicabilité des pratiques de management en Nouvelle-Calédonie dans d’autres environnements multiculturels. La réalisation de recherches longitudinales pour examiner les dynamiques de groupe et l’adaptation des employés aux régulations imposées est également suggérée
L’archivage du numérique et les dispositifs sociotechniques
No full textInternational audiencen France, depuis les années 2000, les réflexions sur l’archivage définitif du numérique se sont orientées vers la conception de plateformes pour gérer la collecte et la conservation, et se sont focalisées sur l’élaboration de réponses technologiques. La question de la finalité des données, de l’intention qu’elles concrétisent, est passée au second plan. Pourtant, les données sont produites par des systèmes d’information qui transforment des informations brutes en une information compréhensible et partagée par l’intermédiaire d’une modélisation. Ces dispositifs sociotechniques produisent des effets de cadrage. Tout n’y est pas visible, et tout n’est pas visible pour tous et toutes. Un système d’information agit dans un contexte de fonctionnement, à la fois composante cognitive et pratique, qui trie, élimine certaines données, en visibilise d’autres, et dans des conditions d’usage. Par ailleurs, l’humain agit aussi sur la technologie, il l’enrichit, voire la détourne. L’archivistique française prend-elle en compte cette dimension lors de la collecte des données ? La contextualise-t-elle ? Comment les plateformes d’archivage électronique, elles-mêmes des dispositifs sociotechniques forcément rigides, figent-elles les règles d’archivage et réifient-elles les données
SPACK, a spatio-temporal database to study the history of whaling, sealing and fishing in the French Southern Islands from the 1780s to the 1930s
No full textInternational audienceThis paper presents the building of a spatial-temporal database called SPACK, dedicated to the presence of hunting and fishing vessels in the waters of the French Southern Islands (TAAF): Saint-Paul, Amsterdam, Crozet and Kerguelen Islands, located between 37∘S and 49∘S latitudes. Although remote and uninhabited, these islands' coasts have been exploited since the late 18th century and integrated into a globalized trade network. Until France re-asserted its sovereignty a century later, they were considered res nullius. Knowledge about the vessels that hunted and fished on these islands was necessary to understand the history of the appropriation and exploitation of natural resources and the issues of public policies to preserve the environment. The SPACK database includes 1,241 hunting and fishing voyages recorded by area, involving twelve departure countries. This paper describes the methods used to collect, select and cross-reference data extracted from disparate and dispersed primary and secondary sources. It discusses the reliability of spatial and temporal data and presents the implementation of the database. Finally, it presents a use case for the SPACK database with a summary of the key findings related to sealing and whaling expeditions
Dark side of the honeymoon: reconstructing the Asian x European rose breeding history through the lens of genomics
No full textInternational audienceRoses hold significant symbolic value in Western cultural heritage, often serving as a symbol of love and romance. Despite their ancient cultivation, the appreciation for the phenotypic diversity of roses emerged relatively recently, notably during the 19th century. This period is characterized by a remarkable expansion in the number of varieties, from around 100 to over 8,000, representing a golden age for roses. To trace the history of rose breeding in Europe and unveil genetic changes during this period, we gathered phenotypic and genetic data from 204 accessions. These included botanical roses and varieties cultivated between 1800 and 1910. Whole-genome sequences from 32 accessions were also included. Our analysis revealed a temporal shift in the genetic makeup, transitioning from a historical European to a near-Asian genetic background within a few generations. This shift was accompanied by a notable reduction in genetic diversity, attributed to the backcrossing with the less diverse Asian genepool, plus some genomic signatures of selection. We have generated the largest GWAS catalog for rose to date, offering a valuable resource for future breeding initiatives. We emphasize the critical importance of preserving ancient rose collections to safeguard diversity and ensure a sustainable breeding for the long term

Engineering the interfaces of 3D-printed polylactic acid scaffolds with bioactive molecules for bone tissue engineering
No full text3D-printed tissue engineering scaffolds have emerged as a substitute to overcome the challenges faced in the reconstruction of bone. The prime objective of the study is to explore the feasibility of plasma-coated 3D-printed PLA scaffolds for bone tissue engineering. By engineering interfaces of these scaffolds with functional molecules, the surface properties can be controlled to ensure better interactions with the cells. To pursue this goal, the surface of these scaffolds was initially coated with polyoxazoline and then functionalized using L-Tryptophan. Hierarchical porous structures composed of meticulously ordered and well-connected pores were evident from the morphological analysis. The surface chemical characterisation revealed successful immobilisation of Ltryptophan on coated samples. The wettability of these scaffolds was favourable for cell adhesion and migration. They exhibited good mechanical properties, cytocompatibility and promoted the proliferation of osteosarcoma bone cells (MG-63). These results show the potential of bio-interface engineering in tailoring the surface properties of scaffolds in bone tissue engineering
