Description : Les abattis Kotika sur la commune de Papaïchton en Guyane sont un haut lieu de mémoire de la population Alouko ou Boni sur le Haut maroni. Les intervenants vont décortiquer le fonctionnement de ce site à partir de documentations administratives et de leurs connaissances du terrain. En effet, la décision de préservation et de conservation est révélateur d'une superposition de motivation politique tant locale qu'internationale. Ainsi, un site patrimonial est un site artistique, historique, scientifique ou légendaire et même dernièrement il a été ajouté le caractère pittoresque avec l'intérêt paysager. Seulement ce sont des critères occidentaux, comment procéder alors à l'adéquation de la conservation et celle de la vie locale ? Pourquoi les populations s'investissent si peu dans ce processus de patrimonialisation ? Est-ce une nouvelle forme de colonialisme administratif ?

Résumé : The UF Smathers Libraries partner with institutions and scholars to host and preserve digital collections, support scholarly publishing with digital collections, and support digital acquisitions to build shared collections. Clear benefits from partnerships are often supported with minimal costs by leveraging UF’s infrastructure for hosting, preservation, publishing, and acquisition. However, digital collections require ongoing support. In addition to the future “care and feeding,” new collections and projects also require support for various needs which may be one-time, infrequent, or a stable and continuous commitment throughout a project. These needs draw from digital curation and other areas (e.g., bulk ingesting materials, training for partners, liaising for grant proposal development, liaising for collection development and outreach, collaboration on activities related to specific projects as with training and outreach). Because of the immediate demands and ongoing commitments required for partnerships, potential new partnerships with the UF Libraries are reviewed for consideration and possible approval. This document provides background on partnerships with the UF Libraries, considerations for reviewing potential new partnerships for approval, and procedures for establishing new partnerships and ensuring optimal ongoing support.

Résumé : LPSC14037
Scientific data collected with modern sensors or dedicated detectors exceed very often the perimeter of the initial scientific design. These data are obtained more and more frequently with large material and human efforts. A large class of scientific experiments are in fact unique because of their large scale, with very small chances to be repeated and to superseded by new experiments in the same domain: for instance high energy physics and astrophysics experiments involve multi-annual developments and a simple duplication of efforts in order to reproduce old data is simply not affordable. Other scientific experiments are in fact unique by nature: earth science, medical sciences etc. since the collected data is "time-stamped" and thereby non-reproducible by new experiments or observations. In addition, scientific data collection increased dramatically in the recent years, participating to the so-called "data deluge" and inviting for common reflection in the context of "big data" investigations. The new knowledge obtained using these data should be preserved long term such that the access and the re-use are made possible and lead to an enhancement of the initial investment. Data observatories, based on open access policies and coupled with multi-disciplinary techniques for indexing and mining may lead to truly new paradigms in science. It is therefore of outmost importance to pursue a coherent and vigorous approach to preserve the scientific data at long term. The preservation remains nevertheless a challenge due to the complexity of the data structure, the fragility of the custom-made software environments as well as the lack of rigorous approaches in workflows and algorithms. To address this challenge, the PREDON project has been initiated in France in 2012 within the MASTODONS program: a Big Data scientific challenge, initiated and supported by the Interdisciplinary Mission of the National Centre for Scientific Research (CNRS). PREDON is a study group formed by researchers from different disciplines and institutes. Several meetings and workshops lead to a rich exchange in ideas, paradigms and methods. The present document includes contributions of the participants to the PREDON Study Group, as well as invited papers, related to the scientific case, methodology and technology. This document should be read as a "facts finding" resource pointing to a concrete and significant scientific interest for long term research data preservation, as well as to cutting edge methods and technologies to achieve this goal. A sustained, coherent and long term action in the area of scientific data preservation would be highly beneficial.

Résumé : Tampa had no existing philanthropic or charitable institutions at the beginning of this immigration wave and, in comparison to other communities, religious institutions played a relatively modest role there. El Centro Español was founded by the Spanish elite who dominated Ybor City, to preserve their identity, provide recreational opportunities and to offer low-cost health care for the many single men and the increasing number of families settling in the area. The club's Sanatorio, completed in 1906, was probably the most modern and complete hospital in Florida at the time.

Résumé : Tourism economic development and traditional culture preservation has been a topic of concern and discussion in academic fields. Based on the development of the tourism economy in Xijiang Miao Village of China, the paper focuses on the analysis of the preservation methods and effects of traditional culture in Chinese ethnic communities. Finally, it points out that the preservation of traditional cultures and tourism development in ethnic communities are not always contradictory. Including the community’s participation can help achieve a “win-win” situation for all actors.
Le développement économique du tourisme et la préservation de la culture traditionnelle est un sujet de préoccupation et de discussion dans les milieux universitaires. Basé sur le développement de l'économie du tourisme du village Miao Xijiang en Chine, cet article se concentre sur l'analyse des méthodes de préservation et leurs conséquences sur la culture traditionnelle des communautés ethniques chinoises. Enfin, l’étude souligne que la préservation des cultures traditionnelles et le développement du tourisme dans les communautés ethniques ne sont pas toujours contradictoires ; la participation de la communauté peut aider à atteindre une situation "gagnant-gagnant" pour tous les acteurs.

Résumé : International audience
STUDY QUESTION: Do freezing and in vitro culture procedures enhance the expression of proteins involved in apoptotic or autophagic pathways in murine pre-pubertal testicular tissue? SUMMARY ANSWER: IVM strongly modified apoptosis- and autophagy-related relative protein levels in mice testicular tissue whereas the impact of cryopreservation procedures was minimal at the end of the culture. WHAT IS KNOWN ALREADY: In vitro spermatogenesis remains a challenging technical issue as it imposes to find a very close balance between survival and death of germ cell natural precursors (i.e. gonocytes and spermatogonia), which will eventually undergo a complete spermatogenesis close to in vivo conditions. The establishment of efficient culture conditions coupled with suitable cryopreservation procedures (e.g. controlled slow freezing [CSF] and solid surface vitrification [SSV]) of pre-pubertal testicular tissue is a crucial step in the fields of fertility preservation and restoration to improve the spermatic yield obtained in vitro. STUDY DESIGN, SIZE, DURATION: Here, we study cryopreservation procedures (i.e. CSF or SSV) and the impact of culture media compositions. A first set of 66 mouse pre-pubertal testes were directly cultured during 30, 36, 38 and 60 days (D) from 2.5 to 6.5-day-old CD-1 mice to evaluate the impact of time-aspect of culture and to endorse the reverse phase protein microarrays (RPPM) technique as an adapted experimental tool for the field of in vitro spermatogenesis. Ninety others fresh, slow-frozen and vitrified pre-pubertal testes were cultured during 30 days for the principal study to evaluate the impact of cryopreservation procedures before and after culture. Thirty-four testes dissected from 2.5, 6.5, 36.5, 40.5, 42.5 and 62.5 days postpartum (dpp) mice, corresponding to the time frames of spermatogenesis orchestrated in vitro, were used as in vivo controls. PARTICIPANTS/MATERIALS, SETTING, METHODS: After in vitro culture, testicular tissue samples originated from 2.5 or 6.5-day-old CD-1 male mice were analyzed using RPPM. This targeted proteomic technique allowed us to assess the expression level of 29 apoptosis- and autophagy-related factors by normalizing blank-corrected signal values. In addition, morphological analyses (e.g. HES, PAS, TRA98 and CREM) and DNA fragmentation in intra-tubular cells (i.e. terminal deoxynucleotidyl transferase dUTP nick end labeling; TUNEL) were assessed for the distinct experimental conditions tested as well as for in vivo control mouse testes. MAIN RESULTS AND THE ROLE OF CHANCE: A validation of the RPPM procedure in the field of in vitro spermatogenesis was completed with assay and array robustness before a principal study concerning the evaluation of the impact of in vitro culture and cryopreservation procedures. The proportion of elongated spermatids and the total cell number per seminiferous tubule tended to be very different between the in vivo and in vitro conditions (P < 0.05), suggesting the presence of a beneficial regulation on the first spermatogenesis wave by intrinsic apoptosis (Caspase₉) and autophagy (Atg5) factors (P < 0.0003 and r2 = 0.74). Concerning the impact of culture media compositions, a basic medium (BM) composed of αMEM plus 10% KnockOut™ serum replacement and gentamicin supplemented with retinol (Rol) and vitamin E (Vit. E) was selected as the best culture medium for fresh 6.5 dpp tissue cultured during 30D with 27.7 ± 8.10% of seminiferous tubules containing elongated spermatids. Concerning the impact of cryopreservation procedures, SSV did not have any impact on the morphological parameters evaluated after culture in comparison to fresh tissue (FT) controls. The proportion of tubules with elongated spermatids on testicular explants cultured with BMRol+Vit. E was not different between SSV (6.6 ± 1.6%) and CSF (5.3 ± 1.9%); however, round spermatids were observed more frequently for SSV (19 ± 6.2%) than CSF (3.3 ± 1.9%, P = 0.0317). Even if the proportion of TUNEL-positive cells for BMRol+Vit. E was higher at D30 after SSV (4.12 ± 0.26%) than CSF (1.86 ± 0.12%, P = 0.0022) and FT (2.69 ± 0.33%, P = 0.0108), the DNA damages observed at the end of the culture (i.e. D30) were similar to respective 6.5 dpp controls. In addition, the relative protein level expression ratio of an apoptotic factor, the phosphorylated FADD on Fas, was reduced by 64-fold in vitrified testes cultured with BMRol+Vit. E. Furthermore, we found in this study that the StemPro®-34 SFM culture medium supplemented with growth factors (e.g. EGF, bFGF, GDNF and LIF) prevented the differentiation of spermatogonial stem cells in favor of a significant proliferation with a better architectural pattern than in vivo 6.5 dpp controls with an increase of seminiferous tubules area for FT (P = 0.0357) and CSF (P = 0.0317). LIMITATIONS REASONS FOR CAUTION: Despite our promising results, the evaluation of apoptotic- and autophagic-related proteins was studied for a limited amount of proteins and on global testicular tissue. WIDER IMPLICATIONS OF THE FINDINGS: The data presented herein will help to improve apoptotic and autophagic understanding during the first spermatogenic wave. Moreover, our findings illustrate for the first time that, using finely-tuned experimental conditions, a testicular in vitro culture combined with proteomic technologies may significantly facilitate the study of cryopreservation procedures and in vitro culture evaluations. This study may also contribute to improve work on testicular tissues from pre-pubertal and adolescent cancer survivors. STUDY FUNDING/COMPETING INTEREST(S): This study was supported by a Ph.D. grant from the Rouen Normandie Université and a financial support from 'la Ligue nationale contre le cancer' (both awarded to L.D.), funding from Institute for Research and Innovation in Biomedicine (IRIB), Agence de la Biomédecine, and co-supported by European Union and Région Normandie.

Résumé : Non-use values (i.e. economic values assigned by individuals to ecosystem goods and services unrelated to current or future uses) provide one of the most compelling incentives for the preservation of ecosystems and biodiversity. Assessing the non-use values of non-users is relatively straightforward using stated preference methods, but the standard approaches for estimating non-use values of users (stated decomposition) have substantial shortcomings which undermine the robustness of their results. In this paper, we propose a pragmatic interpretation of non-use values to derive estimates that capture their main dimensions, based on the identification of a willingness to pay for ecosystem protection beyond one's expected life. We empirically test our approach using a choice experiment conducted on coral reef ecosystem protection in two coastal areas in New Caledonia with different institutional, cultural, environmental and socio-economic contexts. We compute individual willingness to pay estimates, and derive individual non-use value estimates using our interpretation. We find that, a minima, estimates of non-use values may comprise between 25 and 40% of the mean willingness to pay for ecosystem preservation, less than has been found in most studies.

Résumé : International audience
To better understand the microstructural evolution of a "serpentinized" mantle rock and the influence of various hydrous phases on the seismic properties of the mantle wedge, we have conducted the detailed microstructural analyses of a sample of tremolite-chlorite-antigorite schist collected from the Moses Rock dike (central part of the Colorado Plateau). We performed differential effective media (DEM) modelling to study the effect of three hydrous phases forming two-phase aggregates with olivine, considering the crystallographic preferred orientation (CPO) of each phase and the shape ratio of the hydrous phases. We have demonstrated that in a partially serpentinized peridotite, the olivine CPO characteristic of [100](010) dislocation glide is still preserved, and the high-temperature asthenospheric flow is preserved with a foliation normal to that of antigorite schist. The transformation of olivine into antigorite occurs predominantly (~ 75%) by the relationship (100)ol || (001)atg with [001]ol || [010]atg, with the (010)ol || (001)atg and [001]ol || [010]atg relationship observed in areas of weak antigorite CPO. Chlorite results from the phase transformation of olivine in a relatively static environment, as shown by the correlation between the olivine-chlorite CPOs with (100)ol || (100)ch, (010)ol || (001)ch and (001)ol || (010)ch. The fluid percolation that caused the localized metasomatism and partial hydration of the mantle occurred possibly along trans-lithospheric shear zones. The presence of chlorite induces the most important drop on the P-wave velocities and may help to explain some local low velocities in the fore-arc mantle wedges, but is unlikely to be of global importance due to its very high Vp/Vs ratio ~ 1.9. On the other hand, antigorite is the only phase that causes important modification on the propagation directions of P and S-waves, and the only phase to explain the polarization of the fastest shear waves parallel to the subduction trench.

Description : L'adoption par l'UNESCO en 2003 de la convention pour la sauvegarde du patrimoine culturel immatériel a officialisé une rupture dans la notion de patrimoine et a contribué à instaurer de nouvelles dynamiques au sein des groupes ethniques et culturels du monde entier. Sur le plateau des Guyanes, où les traces patrimoniales immatérielles se distinguent par leur importance et leur diversité, de nombreux acteurs oeuvrent à la conservation et à la valorisation du patrimoine intangible. C'est à travers les exemples des expressions orales et graphiques wayãpi, du rituel maraké et d'autres, que nous aborderons la question du patrimoine culturel immatériel : les différentes manières de le préserver et de le valoriser ainsi que les conséquences de cette valorisation.

Résumé : La présente étude a été menée dans les cantons de la préfecture de Doufelgou au Nord Togo. Sur la base de la beauté du paysage, des richesses naturelles et des enquêtes semi-structurées, le potentiel écotouristique de cette préfecture a été évalué. Le traitement des données spatiales collectées a permis de réaliser la carte écotouristique et de proposer un circuit touristique. Trois catégories de potentialités ont été répertoriées : les potentialités naturelles, les potentialités culturelles et les potentialités anthropiques. Ces potentialités peu valorisées subissent à des degrés variables diverses pressions susceptibles de les mettre en péril. Cet article présente ces diverses potentialités et analyse les opportunités socio-économique et environnementale d’un développement écotouristique dans cette zone.
This study was conducted in the cantons of Doufelgou prefecture in Northern Togo. On the basis of the beauty of the landscape, natural resources and semi-structured surveys, the potential ecotourism in this prefecture was evaluated. The treatment of spatial data collected helped make ecotourism map and to propose a tourist circuit. Three categories of potential have been identified: the natural potential, cultural potential and human potential. These potentialities are little valued and suffer to varying degrees various pressures which may put them at risk. This paper presents various potential and carries an analysis on socio-economic and environmental benefits of ecotourism development in this area.

Résumé : International audience
Holocene Lake Mega-Chad (LMC) was the largest late Quaternary water-body in Africa. The development of this giant paleo-lake is related to a northward shift of the isohyetes interpreted as evidence for an enhanced Monsoon (African Humid Period). Numerous preserved coastal features have been described all around the LMC shore. Such features reveal the main paleo-hydrodynamical tendencies. In the context of a closed water-body like LMC, hydrodynamics are forced mainly by winds. We use a three-dimensional numerical model (SYMPHONIE) to simulate the mean hydrodynamics in LMC under both Harmattan-like (northeasterly trade winds) and Monsoon-like (southwesterly winds) forcings. The northern part of LMC displays coastal features, such as sand spits, that are consistent with the simulations forced by Harmattan-like winds. Geomorphic features related to Monsoon-driven hydrodynamics are not clearly expressed. They could have developed during the early stage of LMC but subsequently reworked. At the time of sand-spit building, Harmattan-like driven hydrodynamics prevailed and related coastal features were preferentially preserved in the sedimentary record.

Résumé : Mechanisms controlling the transfer and retention of silicon (Si) along continental margins are poorly understood, but play a major role in the functioning of coastal ecosystems and the oceanic biological pump of carbon. Deep-sea fans are well recognized as carbon sink spots, but we lack knowledge about the importance of the fans in the global Si cycle. Here, we provide a first estimate of the role played by the Congo deep-sea fan, one of the biggest in the world, in the Si cycle. Sediment cores sampled in the deep-sea fan were analyzed to build a Si mass balance. An exceptionally high accumulation rate of amorphous silica aSiO(2) (2.29 +/- 0.58 mol Si m(-2) y(-1)) was found, due to a high sedimentation rate and the presence of aluminum in the sediments. Although favored by bioirrigation, recycling fluxes remained low (0.3 mol Si m(-2) y(-1)) and reconstructed input fluxes could only be explained by lateral inputs coming from the canyon. Preliminary calculations show that the rapid transport of aSiO(2) through the canyon and the excellent preservation efficiency in the sediments imply that 50% of aSiO(2) river inputs from the Congo River accumulate annually in the deep-sea fan. Si:C ratios in deep-sea fan sediments were very low (0.2) and only three times as high as those measured in the river itself, which suggests that material from the river and the continental shelf was delivered directly through the canyon, with very little time for Si and C cycle decoupling to take place.

Résumé : International audience
The rich capital of the French Antilles, Saint-Pierre, was destroyed by the Pelée mountain eruption wich killed about 30 000 people on 8th May 1902. This town still nowadays looks overwhelmed by that tragedy despite the diversity of its natural and marine, religious and military, commercial and administrative heritage. Space was filled again without taking into account the sites and buildings which had existed previously, and efforts in favour of tourism have been limited. The authors first analyse the diversity of these patrimonies, then examine the views and purposes which have divided the people : preservation, development or ignorance.
Ancienne et riche capitale, des Antilles françaises, Saint-Pierre fut détruite le 8 mai 1902 par l’éruption de la montagne Pelée, qui fit près de 30 000 morts. Cette commune donne toujours aujourd’hui l’impression d’être écrasée par cette tragédie, malgré la variété et la richesse de son patrimoine, naturel et marin, religieux et militaire, commercial et administratif. La réappropriation spatiale, s’est faite sans mémoire des lieux ; la mise en valeur touristique et restée limitée. Après avoir analysé la diversité de ces héritages, les auteurs s’interrogent ici sur les logiques qui ont opposé les acteurs, entre préservation, exploitation et ignorance.

Résumé : SUBSURF
Statistical sequential analysis was performed on a series of sediment cores collected from the Têt prodelta in the Gulf of Lions, northwestern Mediterranean Sea, between October 2003 and October 2004. Seabed changes during that period were correlated to hydrodynamic conditions (waves and currents) and river discharge. Low sediment supply prevents full preservation of new sediment strata on this low-accumulation prodelta located on a microtidal, storm-dominated inner shelf. Severe meteorological events caused a rapid succession of erosion and deposition phases. For example, the December 2003 flood and storm produced a flood layer deposit that persisted for 2 months with only slight transformations due to early diagenesis and/or bioturbation, until a new storm event eroded this layer. A typical sedimentary sequence was observed for the secular deposits composed of a 10-cm-thick sandy layer overlaying siltyclayey layers. These characteristic features were used to analyse the last millennia sedimentary record of the Têt prodelta. The low preservation of freshly deposited sediments and variable sedimentation rates during the last millennia period yield a sedimentary sequence formed by the outcropping of muddy prodeltaic units intersected by heterogeneous siltysandy units similar to those formed under present day hydrodynamic conditions. No flood layer was found related to catastrophic flooding of the last century in the sedimentary record. The Little Ice Age ( 1550–1850 AD) probably favoured the formation of a well-developed muddy prodelta in the mouth of the Têt River. Later on, the decrease of sediment supply by rivers due to climate change and/or human activities (damming, irrigation), and the increase of the number of high-energy storms reaching the coast, induced a coarsening of the top sediment layer on this prodelta. This modern change of the substrate is also observed in the composition of benthic biota found in the substrate

Résumé : Cette étude permet une approche distincte de la réflexion sur les ressources marines dans le cadre d’une aire protégée. En effet, les écosystèmes marins sont essentiels d’autant plus, qu’ils présentent en Nouvelle-Calédonie une grande richesse, notamment en termes de patrimoine culturel. Ce sont majoritairement les Kanak qui habitent sur la Côte Est de la Province nord, où la Collectivité et le WWF collaborent à la mise en place de plusieurs aires marines protégées (AMP). Jusqu’à présent, la gestion coutumière Kanak a permis une relative préservation de ces écosystèmes dans un secteur littoral non soumis aux pressions de l’urbanisation, du tourisme ou de la navigation. L’étude s’attache à souligner les enjeux autour de la mise en place des AMP et des perspectives de développement local, sur le milieu marin et les populations locales. Il s’agit de voir comment cette expérimentation est envisagée par les différents acteurs (État, Province Nord, associations, coutumiers, etc.) et de s’interroger sur les mécanismes de gouvernance.
This study allows a distinct approach to thinking about the marine resources in a protected area. Indeed, marine ecosystems are essential, especially as they are in New Caledonia, particularly in terms of cultural heritage. It is mainly Kanak who live on the East Coast of the North Province, where the Community and WWF collaborate on the installation of several marine protected areas (MPAs). So far, the Kanak customary management allowed a relative preservation of these ecosystems in a coastal area not subject to the pressures of urbanization, tourism and navigation. The study aims to highlight the issues surrounding the establishment of MPAs and opportunities for local development on the marine environment and local populations. This is to see how this experiment is considered by the various actors (State, Northern Province, associations, etc. customary). And to consider the mechanisms of governance.
