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.

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.

This case study analyses how far donors implement aid effectiveness principles at health district level in Mali, and why. It shows that not all aid effectiveness principles are implemented at a similar degree. Most projects have limited impact on health services, but many programmes supported by donors offer positive opportunities for health system strengthening. The representations of different categories of stakeholders diverge – notably, regarding the role of different actors in service provision. A number of consistent strategic logics influence actors’ behaviour. We show that while many donors have committed at global level to respect aid effectiveness principles, implementation lags behind.

Introduction Platelet rich plasma injection (PRP) represents a recent therapy for chronic tendinopathies. However, this treatment remains controversial in clinical studies. Summary of the facts and results Based on literature and our experience, we offer few tracks in order to improve this treatment. The optimization of the technique of obtaining the PRP is paramount. Different risk factors must be corrected and the good indications carefully selected. Finally, a post-infiltration rehabilitation remains absolutely necessary. Conclusion Standardisation of the use of the PRP remains necessary in order to optimize the results. [less ▲]

Teeth are the object of multiple attentions and care but unfortunately, it is not the same case of the periodonte, their point of anchoring and essential support. What could be more commonplace than a bleeding arising during the daily brushing? Being not painful, it activates very often no concern and no request of consultation. It is nevertheless about one of the most obvious clinical signs of the periodontal diseases which affect, to varying degrees, practically 90 % of the population in France in all groups of ages and is responsible of the loss from 30 to 40 % of the teeth. For several decades, the scientific world admits a relation between the periodontal disease and certain systematic diseases, as the endocarditis, the atherosclerosis, the diabetes… And what about tendinopathies? Their appearance is often spontaneous without specific medical origin and their cure turns out long and painful. This review has for objective to highlight the relations between the oral hygiene and sportsmen. [less ▲]

Over the last decade, China has deeply affected the economic map of Latin America. All the Latin American countries quickly increased their exchanges with China and get engaged in new plans for exchanges, cooperation and partnerships. These evolutions have highlighted the American lack of leadership and the European loss of competitiveness. Numbers of researches tend to analyse the Sino-Latin American relationship with the eyes of reciprocity. This contribution rather makes the choice of analysing China’s strategy for growth on the world stage, focusing on its ties with Latin America and Brazil especially: cooperation or hegemony? According to this approach, the increase of China’s influence doesn’t only depend on its resources, nor on its capacity to mobilize them opportunely. It also depends on its external recognition. Thus, the power of China can be measured through its capacity to “assert itself as a reference” for its emerging peers, or even for Western powers. By integrating all dimensions of the Chinese power through its foreign policy and its incantatory diplomacy (anti-hegemonism, world multipolarization, South-South cooperation, etc.) , this chapter will try to identify real Chinese influence by measuring the distance between perception and reality. Against the backdrop of the following hypothesis: does the Chinese penetration in Latin America have a notable impact on the relations of Europe and the United States with this part of the world?

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 ▲]

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 ▲]
