To what extent are individual middle Miocene eccentricity-scale benthic foraminiferal carbon isotope maxima (the so-called CM events) related to changes in marine export productivity? Here we use benthic foraminiferal accumulation rates from three sites in the Pacific and Southern Oceans and a geochemical box model to assess relationships between benthic foraminiferal δ13C records, export productivity, and the global carbon cycle. Results from Deep Sea Drilling Project Hole 588 and Ocean Drilling Program Site 747 show a distinct productivity maximum during CM 6 at 13.8 Ma, the time of major expansion of ice on Antarctica. Productivity maxima during other CM events are only recorded at high-latitude Site 747. A set of numerical experiments tests whether changes in foraminiferal δ13C records (CM events) and export productivity can be simulated solely by sea level fluctuations and the associated changes in global weathering-deposition cycles, by sea level fluctuations plus global climatic cooling, and by sea level fluctuations plus invigorated ocean circulation. Consistent with data, the periodic forcing of sea level and albedo (and associated weathering cycles) produces δ13C variations of the correct temporal spacing, albeit with a reduced amplitude. A productivity response of the correct magnitude is achieved by enhancing ocean circulation during cold periods. We suggest that the pacing of middle Miocene δ13C fluctuations is associated with cyclical sea level variations. The amplitude, however, is muted perhaps due to the competing effects of a time-lagged response to sea level lowstands but an immediate response to invigorated ocean circulation during cold phases.

Shallow lakes along minor structural bends or discontinuities of strike-slip fault are not usually paleoseismological target sites. In the present study we show that a 2m deep, 700m long lake crosscut by the North Anatolian Fault contain a reliable paleoseimological record obtain through coring. The North Anatolian Fault, a major strike-slip fault in Turkey last ruptured across the Asacipetecik Lake in 1939 with a slip of about 6 m. Seismic lines still shows remains of the fault ruptures forming minor 10 cm high scarps across the lake. Collected short cores show a set of sedimentary sequences composed of three different units. The lower unit, dark and fibrous, is similar to the present sedimentation at the top of the core. The strongly disturbed and whitish top unit 1 has anomalous organic matter content, grain size and mineralogy. The unit 2 is intermediate in between unit 1 and 3. The present stratigraphy is related to earthquake shaking inducing (1) sediment resuspension; (2) reworking of sediments coming from co-seismic scarps and lake margins; (3) increase in sedimentary runoff into the lake. The 2.5 m long core comprises 4 sequences, and thus 4 sedimentary events. Cesium and Lead data obtained in Boes et al. (2009) imply that Event 1 was triggered by the 1939 M=7.9 Erzincam Earthquake. Radiocarbon age dating suggest that Events 3 and 4 are initiated by the 1254 and the 1045 historical earthquake. Event 2 may correspond to the 1668 earthquake documented in paleoseimological trenches a few kilometers to the east. [less ▲]

This deliverable first analyzes some integration problems encountered during the integration of the O’CoP ontology that was developed by several ontologists. Then, we describe several experiments of development of CoP-specific ontologies · Natural Language processing (NLP) tools were used by Knowledge Management (KM) service developers for analyzing a corpus of e-mails of the @pretic CoP, so as to develop a “Technical Problem” ontology. We also reused an existing hierarchy in order to build the Ontopedia ontology. Last, the development of the ontologies “Human Problems” and “Learning and Teaching” for the @pretic CoP relied on brainstormings between the CoP mediator and the CoP members. · For the Form@Hetice CoP, the ontology was aimed at being used by the BayFac system offering service of document classification, and was developed by the service developers, with a validation by the Form@Hetice CoP mediator. · For Learn-Nett CoP, the ontology was also aimed at being used by the BayFac system, and was developed by the service developers and the CoP mediator (who was also a member of the CoP), with a continuous validation by a CoP focus group. · For the TFT CoP, tbe ontology was developed manually by the CoP mediator through a folksonomy obtained using tags on the CoP documents, according to social tagging approach. At the end of the deliverable, we compare these different ontologies with related work and we analyze them from reusability viewpoint [less ▲]

The present deliverable aims at providing any CoP member, CoP animator or CoP mediator with the most complete view of the PALETTE tools and services. It gives a voice to the developer, the educationalist, the ergonomist and of course the user to explain how they consider them. So, it suggests use cases, scenarios but also shows to the reader where are the obstacles of use (with the aim of avoiding a too quick discouragement on his/her part) and it provides real users’ testimonies. It illustrates the participative design, core of the project, by showing how various kinds of partners in the project work at their evolvement. Several times, it evokes how they interact in that way. More, for the sake of completeness, external services which are "social network" oriented, are described in terms of functionalities and with the concern of providing the audience with a largest view of how ICT may help CoPs to grow up.

The research presented in this deliverable aimed at observing and analysing the use of PALETTE services in authentic CoP contexts. We first present our conceptual framework based on the instrumental genesis theory. We then present our methodology for the generation of data and the analysis. Seven cases of design in use of PALETTE services and scenarios by CoPs are then described and analysed. In the discussion section, we carry out a cross-case analysis aiming at highlighting the common conditions of use of the services through the seven analysed cases. This discussion provides reflection that may inform the use of PALETTE services by other CoPs in other contexts. Finally, in the conclusion, we reflect on our methodological approach and results, and provide guidelines for further research. [less ▲]

This deliverable presents the participatory design methodology of the PALETTE project and some first results of the implementation of this process. Some principles of the Actor Network Theory and of the Agile Methodology are embedded in the different stages of this methodology whose twelve stages (described in details in the last section) will be the basis of the participative development of services and scenarios of use. The first two stages of the process, establishing the collaboration with the CoPs and modelling their activities, have been implemented. Concrete results are available, i.e. procedures implemented to enrol the partners, methodological tools to gather and analyse the data from the CoPs. Some information has been communicated to partners of WPs 2, 3, 4 and 5 that needed it to progress in the development of their work. This process is not ended; it is iterative and will be refined all along the project. [less ▲]

The purpose of this deliverable is to present the researches that have been led for modelling learning and activities in CoPs. On the basis of these models, we developed Learning and Organisational Resources (LORs) that are short activity scenarios aiming at developing learning, collaboration and uses of technological services in CoPs. The LORs are especially focused on the Generic Scenarios developed by WP5 and presented in D.IMP.08 i.e. ‘Reification’, ‘Debate & Decide’, and ‘Identity building’. The LORs have been trialled and evaluated by CoPs. In the conclusions, we synthesize the evaluation accounts from the CoPs and we provide advices for the use of the LORs by CoPs from various domains and contexts. [less ▲]

This deliverable presents services and tools developed during the PALETTE project. Online descriptions, video teasers and printable documents are available from a “Service Gallery”. The teasers provide information from different points of views: a problem evoked by a CoP member, the answer provided by the developer and a supplementary account by a CoP mediator or an educationist. A series of printable documents give information on the services from the developer’s and a learning specialist’s points of views. The interface of the Service Gallery also provides a link to the PALETTE portal. A short survey helps the potential users to choose which service start to explore. A link to the Learning and Organisational Resources and another one to examples of generic scenarios illustrate some potential uses of the tools and services in order to sustain CoP’s activities. From the end of the PALETTE project (February 2009), these resources will be available from a website hosted at the CRP. [less ▲]
