In the Congo Basin forests, local communities used to live from hunting, fishing and gathering, and from slash and burn agriculture. Nowadays, few places remain isolated from the external world, and local practices often have to integrate new parameters. How do family farming and forest activities evolve in a changing landscape, when forest disappears? To answer this question we selected three social and ecological systems positioned in specific places on the forest transition curve (Mather 1992), to constitute a synchronic sample of forested social and ecological system representative of the evolution of Congo Basin Forests. We conducted in 2013 and 2014 a deep analysis of family farming in 8 villages distributed in these 3 studied sites. The method crosses a systemic approach with a systematic approach: agrarian diagnoses were conducted in the three sites (Boulaud 2014; Ferlay 2014) to evaluate technical and economic performances of family farming and forest extractive activities, in parallel, census of households were conducted (Codina Llavinia 2014; Gillet et al. 2014; Lehnebach 2014) to range family activities according to their share in the family income and as subsistence means. Results were harmonized and allowed a deep understanding of the strategy of adaptation to changes of households. [less ▲]

With the underlying hypothesis of a shift toward neoliberal science regimes, much work has been done to analyze the multiple transformations of science institutions and policies over the last decades (e.g. Mirowski and Sent 2008; Slaughter & Rhoades, 2004; Bruno, 2008). The trends towards privatization and commodification of science are undisputable but we argue that little attention has been paid so far to the various political conceptions of research and innovation (R&I) coexisting within neoliberal science regimes. Cognitive approaches to public policy already stressed the circular relationship between meaning and power (e.g. Muller and Surel, 1998; Roe, 1994), but neoliberal science has remained out of the scope of such analyses. Regarding R&I policies, this leads to different ways to conceive of the “value” of science, some related to preexisting institutions and narratives, and some branching out toward new cognitive resources to achieve politico-economic aims. In our proposal, we hypothesize the coexistence of at least four policy narratives which help structuring the representations and actions of scientists and policymakers when they address science as a political object: ‘science for the sake of science’, ‘science, the endless frontier (continued)’, ‘knowledge-based economy’ and ‘grand societal challenges’. Each one attributes a different value to science, proposes a specific organization for the R&I system, and addresses the relation between economy and society differently. In order to understand how these policy narratives are locally articulated, and thereby grounded in R&I policymaking, we analyze the political discourses on science at three different institutional levels (biotechnology labs, university management, science policy advisory boards) in Belgium. Our data were gathered through semi-structured interviews with key members of the institutions studied. By analyzing the interplay of policy narratives for R&I in a context of neoliberal science, we aim to contribute to a better understanding of the ways science is valued at different levels. [less ▲]

Both in Europe and in the United States, scientific research and science, technology and innovation (STI) policies have undergone profound changes in the last thirty years. In the literature, these transitions are often framed along dichotomous lines : an 'old regime' characterized by strong public funding, independent academia and a linear conception of innovation has supposedly been replaced by a 'new regime' in which research and innovation are conceived in systemic terms, regarding their economic and societal relevance (Rip 2000). These conceptions have been criticized regarding their historical accuracy, or regarding their (un)political-reading of those evolutions (Pestre, 2003). More broadly, Nowotny has recently emphasized the fact that the political understanding of science has been black boxed in STS (Nowotny, 2014). My proposal aims at investigating the multiple political conceptions of science in a regional context: what value is attributed to science? What are its aims? How should it be organized and funded? More specifically, this paper relies on an analytical framework based on the notion of "policy narratives" for science to examine how coexisting, and sometimes competing narratives are embedded in situated discourses, policies and practices. Policy narratives include the following elements (Jones & McBeth, 2010): A context, a plot (a sequence with a beginning, a middle and an expected end: Roe, 1992), characters that have a role and intervene in the plot, and some kind of 'moral' of the story advanced as a policy solution. As narratives help actors to make sense of things and orient their actions, they are both descriptive and performative. Hence, they relate to the notion of imaginary in a very concrete sense: narrative are related to actual institutions, and emerging policy narrative can serve as rationale for change. In this paper, narratives like, e.g., the "Knowledge-based Economy", the "Grand societal Challenges", "Science, the endless Frontier", are studied. Each attribute a different public value to science: improving economic growth, tackling specific issues such as cancer or ageing population, or increasing knowledge as a good in itself. Each also propose a specific organization for the STI system, and assign a specific role to the various stakeholders (the scientists, the university authorities, policy makers, industrialists and entrepreneurs, etc.). In order to understand how these global policy narrative are locally articulated, and thereby grounded in regional STI policymaking, my research is based on interviews with a range of stakeholders in Wallonia: biotech lab leaders, members of university boards, and representatives of labor and employers' organizations in regional advisory boards. In the analysis, a particular attention is paid to the various narratives used by the stakeholders when answering broad questions, with regards to their position. More specifically, the way stakeholders depict and scenarize their own role(s) and their relations with other actors is highly political and hence should be assessed. A main thesis of the paper is that one narrative does not constitute the only resource of a (group of) actor(s). Actors refer to different narratives regarding the context and regarding the evolution they promote. [less ▲]

Plant protection strategies are strongly focused today on the development of alternative methods in order to complete or replace conventional chemical inputs. Elicitors of biological origin are increasingly considered as a promising tool as biocontrol agents. They offer the possibility, through the induction of plant natural defences, to preventively protect plants against a large spectra of diseases. Multiple elicitors have already been identified since their first discovery in the late 70s, but few research has been focused on crop pathogens although such diseases can strongly impact both yield and grain quality. We describe hereby a method of elicitor screening to protect wheat against Zymoseptoria tritici. Focus is made on the importance of a good disease infection protocol in order to achieve screening tests. [less ▲]

What are the similarities and differences between the behavior of a small vibrating test system and an F-16 fighter? To find it out, we compare measurements of the test system to measurements from the bolted connection of the wing and the missile of a F-16 Fighter Falcon from the Belgian air force. These measurements were done during a ground vibration test (GVT) campaign. Essentially, the behavior of these systems match, even though the test system is only the heart of a self-study kit for nonlinear system identification and the F-16 is a complex real life mechanical structure. This clearly shows the added value of an experiment driven nonlinear educational system identification package. It provides safe small-scale toy examples for hands-on exercises that react like real systems. We believe that this practical approach lowers the gap between learning system identification concepts and applying it on real systems. [less ▲]

Background: Mesenchymal stromal cells (MSC) are multipotent bone marrow progenitors that have demonstrated significant immunosuppressive effects in various in vivo and in vitro studies. This study aimed to be the first evaluation of the safety and tolerability of MSC infusion after liver transplantation in a prospective, controlled phase-1 study. This study aimed to be the first evaluation of the safety and tolerability of MSC infusion after liver transplantation in a prospective, controlled phase-1 study. Patients & Methods: Clinical grade MSCs were locally collected from the bone marrow of unrelated healthy donors. They were cultured in a GMP-compliant lab, underwent extensive quality controls and were frozen for storage in a MSC bank. When needed for patient treatment, MSC were thawed and intravenously injected into patients. 10 liver transplant recipients under standard immunosuppression (TAC-MMF-low dose steroids until day 30) received 1.5-3x106/kg MSC on post-operative day 3±2. These patients were prospectively compared to a group of 10 control (MSC-) liver recipients. Primary endpoints were MSC infusion toxicity, and incidence of cancer and opportunistic infections at month 6. Secondary endpoints were patient and graft survivals and rejection at month 6, as well as the effects of MSC on recipients’ immune function and on immunohistology of at month 6 graft biopsies. Results: No MSC infusional toxicity was observed. Both groups were comparable in terms of donor and recipient characteristics. There was no difference in primary end-points between control and MSC groups. No patient developed de novo cancer. There was no statistical difference in patient and graft survivals or in rejection rates. There was no graft rejection in the MSC group. Month-6 graft biopsies were not different according to Banff and fibrosis scores. Discussion: This phase 1 study showed excellent tolerability and safety of a single infusion of third-party MSC after liver transplantation. There were no graft safety issues and no excess of immunosuppression after MSC injection. Further analyses of consequences of MSC injection on the immune profile are needed. The possibility of avoiding calcineurin-inhibitors with repeated MSC injections as main immunosuppressive therapy and/of tolerance induction by MSC infusion should be investigated by further studies.

Transcranial magnetic stimulation coupled to high-density electroencephalography (TMS-EEG) allows for directly and non-invasively stimulating the brain and recording the subsequent cortical response. Previous TMS-EEG studies have shown clear-cut differences between conscious and unconscious conditions. When subjects are unconscious, as in non-rapid eye movement (NREM) sleep early in the night (stage N3), anesthesia or coma, TMS typically triggers a stereotypical and local slow-wave response. When they are conscious, as in normal wakefulness and rapid eye movement sleep (REM) sleep, brain responses to TMS are long-lasting, widespread, complex, and differentiated. In this study, we performed TMS-EEG during NREM sleep in stage 2 (N2) and N3 on 7 healthy participants. Brain activity was recorded using a 60-channel TMS-compatible EEG and single-pulse TMS was applied (up to 285 pulses per session) on the superior parietal cortex. After each TMS session (5 to 15 sessions per night), subjects were awakened to ask for a dream report. TMS-EEG responses were analyzed using the global mean field amplitude (GMFA), the perturbational complexity index (PCI), as well as time-frequency measures. Our results show that the TMS-EEG response during N3 is larger and slower than during N2 sleep. The GMFA is higher and PCI is lower in N3 as compared to N2 sleep. Moreover, N3 recordings showed activation at lower frequency bands after TMS as compared to N2 sleep. Additionally, TMS-EEG responses vary depending on whether subjects do or do not report a dream. TMS-EEG might provide valuable information for characterizing neurophysiological fluctuations and levels of consciousness within NREM sleep. [less ▲]

In the present contribution, it is shown that, in the case of mechanical systems where nonlinearities are physically localised, the general structure of black-box nonlinear state-space models can be drastically simplified. A more parsimonious, grey-box state-space representation is derived, which is found to be compatible with Newton's second law of dynamics. For demonstration purposes, black-box and grey-box state-space models of the Silverbox benchmark, i.e. an electrical mimicry of a single-degree-of-freedom mechanical system with cubic nonlinearity, are identified using a maximum likelihood estimator. It is found that the grey-box approach allows to reduce markedly modelling errors with respect to a black-box model with a comparable number of parameters. It is also suggested that the greater accuracy of the grey-box model lends itself to the computation of reliable confidence bounds on the model parameters. [less ▲]

Difficulties in everyday life activities are core features of persons diagnosed with schizophrenia, and in particular during multitasking activities (Semkovska et al., 2010). Multitasking refers to activities (e.g. preparing a meal) where the person has to: (a) carry out and alternate between different tasks that vary in terms of priority, difficulty and duration; (b) define the tasks’ targets; (c) and where the person is faced with unexpected problems during the realization of these tasks (Burgess, 2000). However, the cognitive underpinnings of multitasking abilities have never been adequately explored in schizophrenia. Further, only two cognitive models exist in the literature, which are based on student (Logie et al., 2011) and neurological (Burgess et al., 2000) samples. Both of these models suggest three primary constructs: Memory, Planning and Intent. There are, however, several limitations related to the way multitasking abilities were evaluated in these studies. We thus developed a computerized real-life activity task - the Computerized Meeting Preparation Task (CPMT), which was specifically designed to take into account the multitasking nature of certain everyday life activities. Using this task, and based on previous studies (Burgess et al., 2000; Logie et al., 2011), the aim of the present study was to evaluate multitasking abilities in schizophrenia and to do so in a new cognitive model of multitasking that takes into account certain cognitive functions that are not integrated in existing models. Methods: Fifty-seven individuals with schizophrenia and 41 matched healthy controls completed the CMPT. Participants were also evaluated with a battery of cognitive tests. Results: The results suggest that the CMPT possesses good sensitivity and confirmed the three underlying constructs of multitasking (Memory, Planning and Intent), which were found to be underpinned by several cognitive functions and multitasking aspects. Conclusion: Taken together, this new cognitive model and the CMPT could be a good basis for cognitive interventions of multitasking abilities in schizophrenia. Burgess, P.W., 2000.

Physical processes are known to play major roles in marine plankton succession. However, few studies have addressed the mechanisms that regulate phyto- and zooplankton phenology in a context of changing climate. Here we used a unique long-term (1979-2011) time series performed in a Mediterranean coastal area unbiased by local anthropogenic pressure (PHYTOCLY station, Bay of Calvi, Corsica) to understand how environmental forcing affects the timing, duration and magnitude of the winter-spring phyto- and zooplankton blooms. We showed that phyto- and zooplankton blooms were bottom-up controlled by the establishment of favourable abiotic conditions, i.e. nutrient replenishment by vertical mixing under specific water temperature and wind conditions, for which thresholds were defined. According to the intensity of winter characteristics, there were strong differences in both the abundance and composition of phyto- and zooplankton during the winter-spring period. Our study is consistent with the recent reports that, when occurring, diatoms peaks were added to the initial phytoplankton groups instead of replacing them. In contrast, zooplankton groups followed a replacement sequence. Based on the results provided by our time series, we show that plankton phenology in the Bay of Calvi is highly controlled by climate variation and exhibits contrasted patterns in response to different scenarios of environmental forcing.

The consequences of collision events can range from minor structural damages of the supporting structure to complete collapse of the wind turbine, which may lead to disruptions of the electricity production and, at worst, to sinking of the striking ship with probability of loss of human lives or/and pollution. For all these reasons, a collision risk analysis becomes mandatory at the pre-design stage in order to identify the collision scenarios having the greatest probabilities of occurrence, to estimate the consequences of collision events and to ensure safe operations through the wind farm service life. The goal of this paper is to outline the behavior of the monopile foundations during ship collision by performing non-linear finite element simulations. Many collision scenarios are analyzed in order to study the sensitivity of the monopile to various parameters like impact striking ship velocity, nacelle mass, wind direction, soil stiffness, vertical location of the impact point, wind orientation … The internal energy dissipated by deformation of the monopile, the crushing force and the indentation of the crushed area are compared for different situations, as well as the overall displacements of the supporting structure.

The purpose of the present study was to explore the ability of neglect patients to detect and exploit the predictive value of a cue to respond more quickly and accurately to targets on their contralesional side in a Posner spatial cueing task. The majority of the cues (i.e. 80%) were invalid, indicating that the target would appear on the opposite side, although patients were not informed of this bias. Our results demonstrate that some neglect patients were able to extract the cue’s predictability and use it to orient faster toward the left. This cueing effect was present even in patients who were subsequently unable to describe the predictive character of the cues, and thus was not modulated by reportable awareness of the cue-target relation.

In Belgium, Nuclear Waste Management (NWM) is conducted by a Federal Agency called ONDRAF - i.e. the “National Agency for Radioactive Waste and Enriched Fissile Materials”. Adhering to a largely accepted vision, NWM is considered by ONDRAF as a long-term and complex issue, consisting in technical, social, economic and ethical questions. In this respect, scientific literature invites to clarify and address those aspects in a decision-making process that could benefit from meaningful public participation (Callon, Lascoumes, and Barthes 2001). In this context, many stakeholders (e.g. citizens, researchers, industrialists, civil society organizations, the European Union... and ONDRAF itself) are in demand of a “conductor” that can organize, ensure and legitimize such a participatory decision-making process. Many questions emerge from this demand. Who can be the gatekeeper of this process? What could be his role? For which purposes? In addition to that, how should participation be organized/assessed/controlled? To that regard, the purpose of this paper is twofold. First, I elaborate a possible definition of “gatekeeping a participatory decision-making process concerning NWM in Belgium”. Second, I question the possible role of Technology Assessment (TA) - as an institution as well as a set of approached - in this context. To address those questions, I rely on a combination of theoretical and empirical materials – i.e. semi directive interviews with policy makers and members of Belgian and French agencies in charge of NWM.

Introduction and objectives: Colorectal cancer (CRC) is the second most frequent cancer in women and the third in men. Identification of the mechanisms of progression in these early CRC stages is important to develop new diagnostic and therapeutic tools. Formalin-Fixed Paraffin-Embedded (FFPE) specimens are materials that enable proteomic clinical research. Hence our aim was to address the comparison of FFPE samples from early CRC stages patients using shotgun proteomic analysis. Methods: We performed a retrospective study on 36 CRC tissue samples (pT1N0M0, n=16 and pT2N0M0, n=20) compared together and with 40 control tissue samples (20 patients with diverticulitis, using paired inflamed (DI) and healthy tissue (DH)). Each tissue slice was macrodissected to enrich in epithelial cells. We used FFPE-FASP kit (Expedeon) for sample preparation and protein digests were analyzed using 2D-nanoAquity UPLC separation online with Q-Tof Synapt HDMSTM G2 using ion mobility as additional separation. We performed protein identification and differential analysis using Progenesis QI for proteomics (Nonlinear Dynamics). Results and discussion: We selected 149 proteins differentially distributed between T1 and T2 CRC stages which were not significantly different between CRC and DH or DI. Only 30 proteins were significantly more abundant in T1 versus T2 and 119 were distributed inversely, with a minimum fold ratio of 2. Among those, ATP synthase subunit beta, Aspartate-tRNA ligase, Haptoglobin and Kininogen were identified. . Moreover, we validated Kininogen and 3 others proteins with a significant differential distribution between pT1N0M0 and pT2N0M0 stages by immunohistochemistry. Conclusion: This FFPE retrospective study comparing T1 and T2 CRC highlighted proteins already previously identified as potential CRC biomarkers. These proteins may reflect important early changes in cancer development and may help understanding early tumor progression. [less ▲]

Introduction and objectives: In Crohn's disease (CD), there is a discrepancy between clinical activity of the disease (symptoms) and intestinal healing. However absence of tissue healing is associated with the risk of relapse and tissue damage progression. Endoscopy is costly and invasive. Hence biomarkers correlating with intestinal healing could improve disease management and potentially decrease the number of endoscopy when patients are in clinical remission. Aim: We aimed to identify potential biomarkers associated to CD mucosal healing and relapse after IFX withdrawals by a shotgun label-free proteomic study. Methods: We used the STORI1 clinical trial cohort (n=103) aiming at identifying markers associated to relapse prediction after Infliximab treatment withdrawals. We used serum samples of patients in clinical remission (at base line). We grouped these according to the degree of intestinal healing seen at endoscopy or according to relapse occurrence during the 28 month follow-up and composed pooled samples. We performed depletion of the 20 most abundant plasma proteins on each serum pools and ran a proteomic label-free differential analysis using 2D-nanoUPLC-MSE HDMS Synapt G2 for data acquisition. We performed different statistical analysis. Moreover, a Gene Ontology annotation was also performed for the potential biomarkers highlighted. Results and Discussion: We identified analysing these depleted serum pools 430 different proteins and 188 proteins common to all samples. Among these, 40 were found with a significant differential abundance in the groups compared. We selected some among the most significant one (ratio>1.3) or being by nature consistent with the context of this study (sample origin and clinical question addressed). For example, the C-reactive protein (CRP) was found with a significant Ratio of 2 between Relapsers and Non Relapsers. The other potential biomarkers associated to mucosal healing or to relapse prediction, were selected for further validation by Western Blot analysis (WB), routine laboratory tests and also by a Mass Spectrometry based technology: multiplexed selected reaction monitoring (SRM). Multiplexed SRM will enable quantitative analysis of these candidates in each individual patient as well as WB tests. Conclusions: This research strategy and the validation results on potential biomarkers associated to mucosal healing or relapse after treatment cessation in this cohort of CD patients, as well as tests done on other CD patients, might provide new opportunities for patient follow-up test developments. The next step is to perform SRM validation on the STORI cohort and design signatures using these potential biomarkers SRM data for prognosis power evaluation. 1.

Integrating social and ethical concerns in innovation practice is a well-documented and debated issue in the United States and in Europe (namely through the EU-wide PACITA project). Related developments in other parts of the world are less discernible – at least to Westerns. Yet, as witnessed by the emergence of technology assessment (TA) in countries like Japan, TA and TA-like activities have a unique and long history and continue to play a role in contemporary STI processes (e.g. in the area of citizen engagement with nanotechnologies, or energy policy). Taking these observations as its entry point, this panel asks how STI governance is locally enacted in Asian knowledge-driven economies. Like their Western counterparts, nations like China, Indonesia, Japan, the Republic of Korea, Singapore, Taiwan, etc., have undergone, and continue to undergo, rapid science- and technology-driven industrialization. In these processes, TA and TA-like activities develop with STI policies and programs and typically do so in nation- and region-specific ways. To render these processes, policies, and programs visible, and understand their implications for STI governance, this panel will discuss contributions that: • Describe and conceptualize how TA and TA-like activities have emerged in Asian KBEs, and in what particular forms (e.g. academic and parliamentary TA programs, linked to certain technologies and/or actors, which methods are used and why, etc.). • Reflect how these activities has evolved with, sustained, and/or countered, STI policies on the regional, national, and international level. • Compare and contrast how TA is, or is not, institutionalized in Asian countries and regions, e.g. through initiatives to initiate or abolish various TA forms, such as health TA, early-warning TA, and parliamentary TA; and/or point to prospects for TA capacity building. • Situate the above processes within a broader theory of, and movement towards, new STI governance frameworks, such as anticipatory governance, responsible innovation, public engagement, and/or others. By placing the development in historical, sociological, and comparative perspective, the panel seeks to open a space for critical reflection on the potential, problems, and limitations of initiating TA in Asia and draw connections to STI governance processes in other KBEs across the globe.

When applying a multiscale approach, the material behavior at the macro-scale can be obtained from an homogenization scheme. To this end, at each integration-point of the macro-structure, the macrostress tensor is related to the macro-strain tensor through the resolution of a micro-scale boundary value problem. At the micro-level, the macro-point is viewed as the center of a Representative Volume Element (RVE). However, to be representative, the micro-volume-element should have a size much bigger than the micro-structure size. When considering structures of reduced sizes, such as micro-electro-mechanical systems (MEMS), as the size of the devices is only one or two orders of magnitude higher than the size of their microstructure, i.e. their grain size, the structural properties exhibit a scatter at the macro-scale. The representativity of the micro-scale volume element is lost and Statistical Volume Elements (SVE) should be considered in order to account for the micro-structural uncertainties. These uncertainties should then be propagated to the macro-scale in order to predict the device properties in a probabilistic way. In this work we propose a non-deterministic multi-scale approach [1] for poly-silicon MEMS resonators. A set of SVEs is first generated under the form of Voronoi tessellations with a random orientation assigned for each silicon grain of each SVE. The resolution of each micro-scale boundary problem is performed by recourse to the computational homogenization framework, e.g. [2], leading to meso-scale material properties under the form of a linear material tensor for each SVE. Applying a Monte-Carlo procedure allows a distribution of this material tensor to be determined at the meso-scale. The correlation between the meso-scale material tensors of two SVEs separated by a given distance can also be evaluated. A generator of the meso-scale material tensor is then implemented using the spectral method [3]. The generator [1] accounts for a lower bound [4] of the meso-scale material tensor in order to ensure the existence of the second-order moment of the Frobenius norm of the tensor inverse [5]. A macro-scale finite element model of the beam resonator can now be achieved using regular finite-element, i.e. not conforming with the grains, and the material tensor at each Gauss point is obtained using the meso-scale generator, which accounts for the spatial correlation. A Monte-Carlo method is then used at the macro-scale to predict the probabilistic behavior of the MEMS resonator. As an example the beam resonator illustrated in Fig. 1(a) is made of poly-silicon, and each grain has a random orientation. Solving the problem with a full direct numerical simulation combined to a Monte-Carlo method allows the probability density function to be computed as illustrated in Fig. 1(b). However this methodology is computationally expensive due to the number of degrees of freedom required to study one sample. The proposed non-deterministic multi-scale strategy allows reducing this computational cost as the Monte-Carlo processes are applied on much smaller finite-element models. The method can also be applied in the context of fracture of thin poly-silicon film [6]. In this case, a set of meso-scopic cohesive laws can be obtained at the meso-scale from the resolution of different SVEs. The meso-scopic cohesive laws are obtained for each RVE from the finite element resolution of the Voronoi tessellations using the method proposed in [7]. The resulting statistical values for the critical energy release rate and for the critical strength can then be used for macro-scale simulations. [less ▲]

Cover songs retrieval is a MIR task that has been widely studied in the recent years. The task, in its general sense, consists in retrieving covers for a given audio query. In this PhD, we focus on the more specific task of cover songs *identification*. Given an unknown cover song query, we want to find relevant information about the original song, such as the title, the artist etc. Applications are live music recognition, plagiarism detections, query by examples, etc. Our approach is based on a pruning algorithm, whose role is to discard as quickly as possible as many tracks as possible from a search database in order to keep a smaller subset that should contain the tracks relevant to the query. We introduce the concept of *rejectors* for the pruning algorithm, which are single or combined classifier using multiple audio features for selecting relevant tracks. [less ▲]

Abstract: The aim of this paper is to explore empirically and qualitatively the links between regional organizations and international norms, by using an institutionalism centered on the actors. It seeks thus to analyze the European Union (EU)’s capacity to act within the global governance of culture, and in particular its ability to promote the Convention on diversity of cultural expressions (CDCE) beyond the EU. What is at issue is of why and how the EU foreign cultural policy (EUFCP) uses the CDCE and its normative framework, of what purposes as well as of how the CDCE influences the EUFCP and its objectives. I argue that the CDCE offers an opportunity for the European Commission to establish itself as a foreign policy actor in cultural affairs. Nevertheless, I point out that the disconnect between the Commission and the EU culture organizations is a serious constraint for the effectiveness of the EUFCP, highlighting that the promotion of the CDCE has been especially instrumental in consolidating the Commission’s actorness in external cultural affairs. And finally, I conclude that not only the Commission’s practices largely rely on the willingness of some member states with strong interests in the cultural area, but also the EU’s interpretations on the scope and the goals of the CDCE are far from convergent. Consequently, the Commission’s ability to be a EUFCP’s agent clearly depends on the sensitiveness of the issue and the EU’s actorness is strongly linked to the context in which the EUFCP is made.

Current psychometric research is most often supported by computer software. New research perspectives often imply intensive simulation studies to validate the tested theories or hypotheses, and therefore require accurate implementation as e.g., R packages. However, it may happen that unexpected psychometric phenomena are detected almost accidentally, through such implementations with basically totally different purposes. This talk will illustrate this phenomenon by means of two recent examples from item response theory (IRT) with polytomous models: (a) the equivalence between the weighted likelihood estimator (WLE) and the Bayes modal estimator with Jeffreys prior, and (b) the relationships between observed and expected information functions. Rather than focusing on the technical details, the purpose of this talk is to highlight how the results were identified first through R implementation, then confirmed by theoretical derivations. The talk concludes by advocating for flexible and stable open-source implementations (such as R packages) to support current and ongoing psychometric research. [less ▲]

- Introduction : Pathogens have co-evolved with their host to ensure efficient replication and transmission without inducing excessive pathogenicity that would indirectly impair their persistence. This is exemplified by the bovine leukemia virus (BLV) system in which lymphoproliferative disorders develop in ruminants after latency periods of several years. Infection of sheep and cattle with BLV is a model system for the related human T-lymphotropic virus type 1 (HTLV-1) responsible for Adult T-cell Leukemia (ATL). - Aims : The goal of this work is to investigate the role of N-glycans of the viral envelope protein during viral replication and pathogenesis. - Methods and results : Using glycosylation inhibitors and lectins, we showed that N-glycosylation is involved in viral infection (i.e. cell-to-cell fusion). Using reverse genetics of an infectious molecular provirus, we next demonstrated that a particular N-linked envelope glycosylation site (N230) limits viral replication and pathogenicity in vitro and in vivo. We have thus generated a viral mutant that is more pathogenic than the wild type strain. - Conclusions : To our knowledge, this is the first time that a hyperpathogenic BLV has been identified. This unexpected observation has important consequences in terms of disease control and managing. Indeed, during evolution, pathogens and their hosts should achieve an equilibrium allowing the coexistence of the two species. Occurrence of this particular mutation may thus represent a potential threat associated with emergence of hyperpathogenic BLV strains and possibly of new variants of the related HTLV-1. [less ▲]

Envisager les études sur la mémoire comme sous-champ de la science politique francophone ouvre des pistes enrichissantes pour les politologues, notamment lorsqu’ils sont amenés à analyser les instruments mémoriels régissant un ou plusieurs système(s) politique(s). Dans cette perspective, la communication vise à présenter, d’un point de vue épistémologique, les apports découlant de l’interaction entre les sciences politique et juridique dans le processus de consolidation des études sur la mémoire comme sous-champ disciplinaire de la science politique. Plus précisément, la communication vise à offrir une typologie des instruments mémoriels en fonction du degré de contrainte et d’imposition d’une mémoire officielle. Par exemple, une résolution adoptée par une assemblée législative est faiblement contraignante alors qu’une loi réprimant le négationnisme impose à la fois une mémoire officielle tout en sanctionnant pénalement les citoyens qui ne la respectent pas. La typologie passe en revue les multiples instruments mémoriels pouvant être adoptés par les autorités publiques : résolution, loi déclarative, loi pénale, plan de commémorations ou encore mise en valeur d’un lieu de mémoire. L’accent est mis sur les instruments mémoriels de deux pays francophones : la Belgique et la France. Au final, cette communication permet d’insister sur l’apport de la science politique en analysant l’exercice de prérogatives de puissance publique et sur l’apport de la science juridique en classifiant les types d’instruments mémoriels en fonction du degré de contrainte ; tout en faisant dialoguer des cas d’étude différents.

In the new Turkish doctrine, besides the great interests in Central Asia, Middle East, Africa and the Caucasus, the Balkans are also important. Turkey is making great efforts to play a greater role on the international scene and creates its area of interest, especially where the links of Ottoman legacy can help. Although it is defined as a peaceful power in the region, some describe it as neo-ottoman, a term rejected by the Turkish authorities because of its possible imperialist connotation. This paper aims precisely to study the return of Turkey to the Balkans. Our central question is: what is the purpose of the Turkish foreign policy in the Western Balkans? Related issues will be addressed such as: is there a competition between Turkey and the European Union in this area? What are the specifics of Turkish foreign policy? In order to explore these research questions, this study focuses on the concept of soft power through which Turkey extends its power. Indeed, the Turkish government imposes itself on the Balkans not by force but with the help of economics, diplomacy, trade, culture and religion. Following the crisis in the EU, causing the collapse of Western investment and a relative decrease of attraction for the Balkans, Turkey has taken advantage of the situation in order to increase its influence in all areas. This contribution will proceed in three stages. Firstly, we will make an analysis of the authors of soft power to think about the character of the new Turkish geopolitical doctrine. Secondly, we are going to apply this theoretical framework to the case study identified, namely the influence of Turkey in the Western Balkan countries. Finally, we will show if exists a competition or a cooperation between Turkey and European Union in the Western Balkans. [less ▲]

Dans une perspective de gestion mixte du marché du travail, les services publics de l’emploi sont invités, par la Convention 181 de l’OIT de 1997, à déléguer et à confier l’exploitation et la gestion de leurs activités à des opérateurs privés de service, dans le cadre d’une entente contractuelle. Alors que les modalités de la collaboration (telles que le public-cible, le type et le nombre d’accompagnements dispensés, les résultats à atteindre, etc.) sont fixées, initialement, par les services publics de l’emploi, elles sont ensuite mises en pratique par les diverses parties-prenantes du partenariat. Les acteurs publics et privés exploitent la part de latitude inhérente à leur fonction pour interpréter et ajuster les termes du contrat ou pour pouvoir réaliser leur mission d’accompagnement des demandeurs d’emploi. Partant du postulat que la règle est incomplète, notre objectif est d’analyser la mise en œuvre du partenariat en saisissant les arguments avancés par les acteurs pour justifier et légitimer leurs actions. À partir de cette analyse, nous montrerons que les acteurs du partenariat doivent interpréter les règles – écart entre le travail prescrit et le travail effectivement presté – dans leurs pratiques quotidiennes. Agissant comme des « pseudo » street-level bureaucrats, ces derniers usent de leur pouvoir pour ajuster les règles. En outre, il semblerait que ces pratiques d'indiscipline permettent, en réalité, de maintenir les relations partenariales entre services publics de l’emploi et opérateurs privés, et d’œuvrer, in fine, à la pérennisation de celles-ci dans le champ de l’emploi. Nous appuierons notre analyse sur un matériau empirique composé d’observations participantes et d’entretiens semi-directifs réalisés auprès des parties-prenantes des PPP, situés en Belgique francophone.

Meat is worldwidely known to be a nutrient rich food. It provides valuable amounts of proteins,vitamins such as retinol and vitamin B12 and minerals namely iron, selenium and zinc with an increased bioavailability than found in other dietary sources [1]. Along the production chain, meat can get contaminated by a wide range of spoilage and/or pathogenic microorganisms from the farm, slaughtering environment and distribution. The actual number of foodborne infections attributable to meat is difficult to assess accurately, principally because only a small proportion of illness cases is officially reported. However, by using outbreak data published internationally, Greig and Ravel [2] reported that 12.7 % of reported foodborne outbreaks were attributable to beef while 10.5 and 4.6 % were associated with chicken and pork, respectively. According to the same authors, Salmonella spp. and pathogenic E.coli, respectively, were identified as the causal agents in 32.9 and 34.6 % of foodborne outbreaks of bacterial origin attributable to beef. The objective of this study was to determine the meat consumption pattern in different socio-conomical categories of the population of Kigali city and to assess the bacteriological quality of the consumed meat.

Aujourd’hui, la résistance des bactéries aux antibiotiques relève d'une préoccupation croissante dans le domaine de la santé publique et s'impose plus que jamais comme une priorité. Ce problème a un coût, sociétal et économique en Europe: 25.000 décès annuels par septicémie et 1,5 milliard d’euros d’augmentation du coût des traitements. Bien que le besoin de nouveaux agents antibactériens en milieu clinique est urgent, seules deux nouvelles classes d’antibiotiques ont pu être proposées durant ces 30 dernières années. En effet, la découverte et le développement de nouveaux antibiotiques posent des défis scientifiques, cliniques et financiers importants. [less ▲]
