Study design: This consisted of a translation and validation study. Background: Acute hamstring injury is a frequent muscle strain in sports that require high explosive strength, impulsion or running phases. Therefore, the Functional Assessment Scale for Hamstring Injury questionnaire was developed to assess pain, physical activity level and ability to perform various exercises in patients with hamstring injuries. The Functional Assessment Scale for Hamstring Injury questionnaire is currently available in English, German, and Greek. Objectives: The goal of this study was to provide a cross-culturally adapted French-translation of the FASH questionnaire and to assess its psychometric performance. Methods: The French-translation and cross-cultural adaptation process were based on international recommendations, following six rigorous steps: (a) two initial translations from English to French; (b) synthesis of the two translations; (c) back-translations; (d) comparisons between the back-translations and the original questionnaire by an expert committee; (e) pretest; and (f) approval of the final French version of the Functional Assessment Scale for Hamstring Injury questionnaire. To validate this French version, 116 subjects (17 pathological patients, 19 patients with other muscle injury, 40 athletes at risk, and 40 healthy control athletes) were recruited to complete the Functional Assessment Scale for Hamstring Injury questionnaire. The Short Form Health Survey (SF-36) was used as a comparative questionnaire. The psychometric properties of the questionnaire were evaluated by determining the test-retest reliability after a 48–60-h interval, internal consistency, construct validity, and floor/ceiling effects. Results: All of the items of the Functional Assessment Scale for Hamstring Injury questionnaire were translated without any major difficulties. The questionnaire showed excellent discriminative power by obtaining significantly different scores from the four groups (p¼0.01). Regarding psychometric performances, the test–retest reliability was excellent (IntraClass Coefficient Correlation of 0.997). Very high internal consistency was also observed (Cronbach’s alpha of 0.969). Correlations with the physical health subscales of the SF-36 were significant and considered to be strong, indicating an excellent convergent validity. The other subscales of the SF-36 (mental health) were weakly correlated with the FASH, reflecting good divergent validity. No floor or ceiling effects were observed. Conclusion: The French-translation of the Functional Assessment Scale for Hamstring Injury questionnaire and its cross-cultural adaptation can be considered to be successful. Functional Assessment Scale for Hamstring Injury-French questionnaire is now a reliable and valid tool for patients suffering from acute hamstring injury, and its application in clinical practice is particularly relevant. IMPLICATIONS FOR REHABILITATION The FASH-F can be considered to be discriminant, reliable and valid for the evaluation of the severity of symptoms and sports ability in individuals with hamstring injuries. FASH-F is now a reliable and valid tool for French-speaking patients suffering from acute hamstring injury, and its application in clinical practice is particularly relevant. A limitation of our study could be that the distribution between the different study groups was not homogeneous implying that our findings may not be fully representative of the general population.

This essay offers a reading of Shelley's "Julian and Maddalo" as a Detective Story, or rather, as a metacognitive mystery tale. The poem indeed asks important questions about the possibility and reliability of knowledge. The detective-poet's quest for higher truths is confronted with the impenetrable forces of the sublime and the grotesque and is thus bound to remain unfulfilled. Interpretation is further complicated as the roles of detective, criminal, and victim are gradually interwoven and Julian's faith in human free will is threatened by a reality in which mere chance leads those who desperately try to produce meaning to madness and death.

Purpose: Quality of life (QOL) of a patient is usually computed as the (weighted) sum of items and analysed by means of multiple regressions to evaluate its relationships with various measured factors. The aim of the present study was to compare results derived under classical statistical method with those obtained under more appropriate statistical techniques for QOL. Methods: Analyses were applied to data from 4155 subjects participated in 2012 in a community based sample study in the French speaking part of Belgium and which completed a web-based questionnaire on their weight-related experience. Confirmatory factor analysis (CFA) and structural equation modeling (SEM) were carried out to derive QOL and to test direct/indirect effects of body mass index (BMI), age, body image discrepancy (BID), latent socio-economic (SOCIO) and latent subjective-norm (SN). Results: No major differences were found under both SEM and the product of coefficients approach using SAS PROCESS macro developed by Hayes. Significant direct and indirect effects on physical and psychological dimensions of QOL were found for age, BMI and SOCIO while significant direct effects were found for BID and SN (p < 0.0001). Factor loadings were found to be significantly different according to gender (p < 0.0001). Conclusions: BID and SN are partially mediators on the relationships between BMI and QOL. The study also confirms the role of SOCIO on the (un)observable variables included in the model. However, the large sample size provided significant tests with small effect size and couldn’t highlight pertinent differences between both methods. [less ▲]

Alexithymia and Openness to Emotions (OE) are strongly linked to mood disorders. Alexithymia represents the difficulty of giving words to emotions, whilst OE refers to cognitive representation, communication and regulation aspects of emotions. We investigated variables impacting both alexithymia and OE for mood disorder patients (N = 73), before and after a treatment period in a day psychiatric hospital. Significant score changes and, notably, significant impacts of perceived social support were expected. [less ▲]

La taxe Caïman ou taxe de transparence pour but d’imposer les revenus des patrimoines qui sont artificiellement séparés du patrimoine du contribuable . Cette taxe vise tant les personnes physiques que les entités soumises à l’impôt des personnes morales (I.P.M.) , et donc notamment les A.S.B.L. qui sont soumises à cet impôt . Dans cette contribution, nous proposons un aperçu général des éléments caractéristiques de ce dispositif fiscal pour les assujettis à l’I.P.M., à savoir les différentes définitions des notions-clés (A.), le principe même de la transparence fiscale (B.), l’application différenciée selon la catégorie d’assujettis à laquelle le contribuable appartient (C.), les exceptions à l’application du régime (D.). Pour que l’I.P.M. – et partant la taxe Caïman – puisse être appliqué, l’assujetti devait en principe posséder la personnalité juridique. Le législateur vient de revoir ce principe en rendant possible l’application de la taxe Caïman aux associations de fait. C’est par ces dernières considérations que nous achèverons notre exposé (E.).

Renommée depuis la plus haute antiquité pour son ancienneté et son excellence, la médecine égyptienne a-t-elle pu influencer la médecine occidentale et, si tel est le cas, en quoi et de quelle manière ? Que s’est-il passé lorsque la médecine grecque héritée d'Hippocrate a été importée en Égypte à la suite de la conquête du pays par Alexandre le Grand, en 332 avant notre ère ? Après avoir comparé les écrits médicaux égyptiens et grecs et les pratiques médicales attestées dans le Pays du Nil et dans le monde hellénique, on examinera, à côté des sources littéraires qui font de l' « école médicale d'Alexandrie » un modèle qui restera pour longtemps inégalé, les papyrus médicaux grecs (des IVe/IIIe siècles avant notre ère au VIIe siècle de notre ère), retrouvés en nombre sans cesse croissant dans les sables égyptiens, ainsi que d'autres sources archéologiques, en vue de répondre à ces questions.

En plus de donner au concept de « désituation » une assise définitoire, je chercherai à l’inscrire dans la généalogie sartrienne de la notion de situation. Je ferai reposer mon argumentation sur la notion de situation dans l’Esquisse d’une théorie des émotions. Ce détour me permettra de relier la situation à la problématique émotionnelle qui lui est indissociable, tout en suggérant que la désituation rejoue cette dimension de l’éprouvé affectif. Enfin, et je justifierai par-là mon titre, j’utiliserai la notion de désituation dans le champ de la psychopathologie, plus particulièrement de la psychose schizophrénique. Pour ce faire, je vais convoquer les propositions contemporaines de la psychopathologie phénoménologique qui identifient des anomalies de l’expérience du soi et du rapport au monde en tant que caractéristiques centrales de l’éprouvé schizophrénique. Mon objectif consistera à démontrer que l’hypothèse de la désituation permet de peaufiner ces modèles de compréhension psychopathologique de référence et, dès lors, nous le verrons, d’identifier des zones de proximité entre l’expérience de l’artiste, en l’occurrence Flaubert, et celle du schizophrène, campée par deux patients : Séraphine et Fabien.

Following a heated local controversy over the construction of a waste incinerator in the Fos-sur-Mer industrial area near Marseille, residents pointed to the lack of knowledge of the industry’s cumulative impact on their health and environment. Under pressure, some of their representatives supported the creation of an independent scientific organization, the Ecocitizen Institute for Pollution Awareness (IECP). Its aim was to conduct independent, localized scientific research on the chronic effects of pollution, and to lobby the administration to change its regulatory practices. This paper examines the work of the IECP to ensure that the “undone science” (Frickel et al. 2010) of pollution and its impacts gets done, by focusing on the specificities of this highly industrialized site. We look at a participatory biomonitoring experiment aimed at documenting pollution in the Gulf of Fos, where scientists working for the IECP accepted anglers’ concerns and requests and switched from a standard sentinel species to another species (conger or Conger conger). We tell the many stories that were shared with us about how congers qualified as a more suitable “cosmopolitical fish” in the study of pollution. Elaborating on actor-network theory and multispecies ethnographies, we go on to discuss the appropriacy appropriateness and success of congers as the newly appointed sentinel species aiding the detection of mercury and PCB contamination hotspots. We argue that this demonstrates the importance of the “ecology of multispecies relations” (Stengers 2010) in maintaining the livability of the area. [less ▲]

Transgender MtF people (trans women) consult otorhinolaryngologists and vocologists with the aim of feminizing their voice and being consistently perceived as women. Treatment of these trans women always begins with a vocal assessment that is relatively unspecific as it was originally constructed for individuals with dysphonia. OBJECTIVES: This study examines the subjective portion of the assessment and specifically the self-assessment questionnaire. There is no French-language questionnaire designed to identify the issues facing people who want voice feminization and quantify the impact of their voice disorder on their daily lives. We present a translation and adaption into French of the questionnaire developed by Dacakis et al [6]. METHODS: This work follows the World Health Organization recommendations [12] regarding translation. Thirty-six Belgian and French trans women took part in this study. RESULTS: The results show excellent repeatability and reliability, while the construct validity measures show that the items correlate with six areas of concern for trans women identified by Davies and Johnson [7] in a previous study. The domains are the following: effect of voice on ease of social interaction, effect of voice on emotions, relationship between voice and gender identity, effort and concentration required to produce voice, physical aspects of voice production, and pitch. Concurrent validity could not be measured owing to lack of sufficiently detailed stories. CONCLUSION: The psychometric properties of the French version of the questionnaire are acceptable. The questionnaire can be used as is in daily clinical practice. [less ▲]

The competences expected from early childhood education and care professionals have evolved significantly in our Western countries following the transformation of services and the affirmation of their educational function. This article is based on action research projects carried out in the Wallonia Brussels Federation (FWB) which integrate an analysis of other education and training systems (France, Flanders, England, Sweden and Quebec). It presents a reflection on the development of professional competencies and their acquisition from the initial training in a holistic approach to education. It notes that a diversity of formations coexists, leading to an absence of clear view on professional skills and profiles. In response to this observation, it proposes a modeling that articulates organizational, relational and reflexive competencies that are needed for the development of a professional posture. That modeling is presented as a grid of analysis that can enable better understanding of the complexity of early education and care in its many dimensions (working with children, families, professionals and the local community). It can be considered as a tool to globally rethink initial and continuing education and training in a systemic perspective. [less ▲]

Acute myeloid leukemia (AML) is an aggressive hematopoietic malignancy generally associated with poor prognosis. Allogeneic hematopoietic cell transplantation (alloHCT) continues to be the most potent anti-leukemia treatment for adult patients with intermediate and high-risk AML. However, disease relapse after alloHCT remains unacceptably high and is the primary cause of treatment failure and mortality following alloHCT. It is therefore that post-transplant early cellular or pharmacologic maintenance or preemptive strategies to enhance the graft-versus-leukemia effect or to eradicate persistent minimal residual disease have been of renewed interest, particularly with the availability of more sensitive technologies to measure residual AML. Although preliminary studies have demonstrated improved outcomes with the use of post-alloHCT remission therapies, prospective randomized trials are required to determine their clinical efficacy and role in the treatment of AML. On behalf of the Acute Leukemia Working Party of the European Society for Blood and Marrow Transplantation, we summarize the available evidence on the use and efficacy of available pharmacologic post-remission therapies, including hypomethylating agents, deacetylase inhibitors, and tyrosine kinase inhibitors, as well as cellular therapies, including preemptive and prophylactic donor lymphocyte infusions for the prevention of relapse of AML. © 2018, Springer Nature Limited.

The revised Motor Behavior Tool (MBT-r) is a clinical complementary tool aiming to identify subtle motor behaviors that might reflect residual cognition in DOC. In this prospective study including 30 DOC patients in the early stage after brain injury, we show that the revised MBT-r has an excellent inter-rater agreement and has the ability to identify a subgroup of patients, underestimated by the Coma Recovery Scale-Revised, showing residual cognition and a subsequent recovery of consciousness.

A classification for peri-implant diseases and conditions was presented. Focused questions on the characteristics of peri-implant health, peri-implant mucositis, periimplantitis, and soft- and hard-tissue deficiencies were addressed. Peri-implant health is characterized by the absence of erythema, bleeding on probing, swelling, and suppuration. It is not possible to define a range of probing depths compatible with health; of more importance are the clinical signs of inflammation. Peri-implant health can exist around implants with reduced bone support.The main clinical characteristic of peri-implant mucositis is bleeding on gentle probing. Erythema, swelling, and/or suppuration may also be present. An increase in probing depth is often observed in the presence of peri-implant mucositis due to swelling or decrease in probing resistance. There is strong evidence from animal and human experimental studies that plaque is the etiological factor for peri-implant mucositis. Peri-implantitis is a plaque-associated pathological condition occurring in tissues around dental implants, characterized by inflammation in the peri-implant mucosa and subsequent progressive loss of supporting bone. Peri-implantitis sites exhibit clinical signs of inflammation, bleeding on probing, and/or suppuration, increased probing depths and/or recession of the mucosal margin in addition to radiographic bone loss. The evidence is equivocal regarding the effect of keratinized mucosa on the longterm health of the peri-implant tissue. It appears, however, that keratinized mucosa may have advantages regarding patient comfort and ease of plaque removal. Case definitions in day-to-day clinical practice and in epidemiological or diseasesurveillance studies for peri-implant health, peri-implant mucositis, and periimplantitis were introduced. The proposed case definitions should be viewed within the context that there is no generic implant and that there are numerous implant designs with different surface characteristics, surgical and loading protocols. It is recommended that the clinician obtain baseline radiographic and probing measurements following the completion of the implant-supported prosthesis. [less ▲]

WVO Quine questions the « myth » of an ideal realm of shared meanings which every national language would express in its own way. Against the hope of transparent translations, he insists on the necessity for building equivalences from one language to another through a strategy of reducing the differences in rationality among nations as much as possible. According to Quine, otherness is not insuperable impediment to meeting/encounter and mutual understanding ; by throwing our conceptual schemes on the other communities’ uses/practices – which of course involves some symbolic violence – gaps can always been narrowed. Similarly E. Laclau questions the traditional conception of political representation, which is seen as the transparent process of transmitting someone’s will or interests on another level. For this ideal conception of representation, Laclau substitutes a pragmatic conception which takes in account the irreducible gap between the actors as well as the constitutive opacity of the process of representation : the subject’s will is constituted within the process of representation and through the representative’s productive role. In order to be transposed at the decision-making level, the subject’s interests must be translated by the representative as well as be negotiated with the other represented interests. This implies that the initial will undergoes some identity transformations. [less ▲]

This article focuses on technologies of mobility for people with physical disabilities living in a South African poor urban setting. It moves away from a perspective that exposes limitations to underline specific opportunities for people with disabilities to design the city. In the township of Mitchell’s Plain (Cape Town), known for its violence, defining when and where to use the chair involves a negotiation of moral and medical norms with a pursuit of security. In this process, the wheelchair constitutes one element of a larger continuum of wheeled mobility. The availability of public and private alternative transport enhances already present inequalities among people with disabilities. Two systems of public transport are further discussed, namely Dial-a-Ride (a specialized transport) and MyCiTi bus (a mainstream service). Initiatives of the City of Cape Town, these transports are widely discussed and criticized by people with disabilities. Through discussion with or opposition to the local government, associations participate actively in their inclusion in the post-apartheid city. My conclusions, drawn upon nineteen months of ethnographic fieldwork, call upon the theoretical framework of the anthropology of material things and the sociology of space. [less ▲]

En repartant de la notion de « société du risque », la présente étude entend montrer pourquoi la Cour européenne des droits de l’homme est amenée à évaluer des risques et comment elle y procède. À cette fin, deux approches différentes de la jurisprudence sont déployées. D’une part, à travers une lecture juridico-linguistique, on cherche à recenser et à examiner les principales expressions que la Cour utilise couramment pour traiter les cas pertinents. D’autre part, par le biais d’une approche juridico-économique, on essaie d’appliquer les grands principes de la théorie de la gestion du risque (gravité, probabilité et acceptabilité) à cette même jurisprudence, avec l’intention de contribuer à une lecture originale des arrêts de la Cour.

There is increasing emphasis on patient-centred research to support the development, approval and reimbursement of health interventions that best meet patients’ needs. However, there is currently little guidance on how meaningful patient engagement may be achieved. An expert working group, representing a wide range of stakeholders and disciplines, was convened by the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) and the World Health Organization (WHO). Through a structured, collaborative process the group generated practical guidance to facilitate optimal patient engagement in clinical development and regulatory decisions. Patient engagement is a relational process. The principles outlined in this report were based on lessons learned through applied experience and on an extensive dialogue among the expert participants. This practice guidance forms a starting point from which tailoring of the approach to suit different chronic diseases may be undertaken. © 2019, The Author(s). [less ▲]

This work aims at measuring experimentally proton induced secondary electron energy spectra after interaction with Gold Nano Particles (GNPs) and polymer-coated GNPs. Backscattered electron energy spectra were collected over a 0 to 1000 eV energy range using a Retarding Field Analyzer. This paper presents the spectra obtained for proton beam energies of 0.5 and 2 MeV and diameter 2.5 and 3.8 nm GNPs. The spectra were also measured for 3.8 nm GNPs after 5 and 10 MeV proton irradiations. GNPs were deposited on a 100 nm carbon film. Each experimental spectrum was compared with dedicated simulations based on existing numerical models used in the TRAX and Geant4 Monte Carlo codes. For 100 nm carbon target, good agreement between experimental, TRAX and Geant4 simulation results can be observed. For 3.8 nm GNPs, the TRAX simulations reproduce with good agreement the electron energy spectra produced after 0.5, 2, 5 and 10 MeV proton irradiations, while Geant4 spectra display a lower secondary electron yield at low energy (<600eV) for all the studied energies. This underestimation can mostly be explained by the 790 eV threshold applied in the condensed history model used by Geant4 which impacts the secondary electron energy distribution. Results obtained for carbon and gold targets highlight the impact of the secondary electron production threshold for proton ionization process considered in condensed history models. The experimental results demonstrate that the single interaction approach used in TRAX is adapted to reproduce secondary electron emission from GNPs. On the other hand, the standard electron generation threshold implement in G4BetheBlochModel and G4BraggModel condensed-history models used in Geant4 is not adapted to reproduce low energy electron emission in gold targets. Finally, the results highlight that the GNP coating leads to a decrease of the electron yield and mostly affects low energy electrons (<500eV) emitted from GNPs. [less ▲]

Le monde des études littéraires a vu se développer, au cours de ces dernières années, une théorie des textes possibles qui confronte la réception traditionnelle des œuvres (c’est-à-dire la façon dont leur lecture se concrétise la plupart du temps et le commentaire qu’on en livre habituellement) à une réinvention de leur signification, tirant parti des impensés de la fiction, des non-dits, des interactions interrompues, des blancs, des inférences labiles et autres zones creuses du récit qui offrent des prises pour une renégociation herméneutique. À côté des réinventions herméneutiques des œuvres classiques, de l’approche génétique et du fantasme programmatique autour des productions perdues, la critique des textes possibles aurait tout à gagner à explorer un continent fictionnel, fructueux en termes d’œuvres en puissance et qui recèle d’indications sur l’évaluation des modes et tendances d’une époque émanant des représentations des écrivains eux-mêmes : les œuvres imaginaires qui n’existent qu’en tant qu’elles sont inscrites dans d’autres œuvres, qui en esquissent les contours, les présentent voire les citent. Celles-là sont au cœur de la présente enquête, menée à partir du corpus rassemblé dans la base de données du GREMLIN ; on interroge dans cette contribution la façon dont, par métonymie, elles contribuent à une représentation fictionnelle de la vie littéraire.

Les troubles du sommeil sont fréquents chez l’enfant et leurs origines sont diverses. Ces troubles ont leur ancrage dans le développement neurophysiologique et psychoaffectif de l’enfant. Les enfants souffrant de troubles du spectre autistique présentent un déficit de sommeil, qui peut durer jusqu’à l’adolescence. Les troubles du spectre autistique comportent des comorbidités multiples, dont des altérations du sommeil. Ils sont importants à caractériser dans cette population, car ils peuvent avoir un impact négatif sur les comportements diurnes. Par ailleurs, ils entrainent souvent des difficultés au sein de la famille. La prise en charge doit avant tout prendre en compte le contexte environnemental afin d’améliorer les habitudes et l’hygiène du sommeil. Des questionnaires ainsi que des agendas de sommeil ont été remplis par des parents afin de démontrer l’importance d’une évaluation et d’une prise en compte des troubles du sommeil chez les enfants souffrant d’autisme en consultation pédopsychiatrique.

This article discusses some difficulties of the theory of color propounded by Meinong in his Re-marks on the Color Solid and the Mixture Law of 1903. First, I argue that Meinong’s geometrical approach faces at least three sets of difficulties related to the following assumptions: colors pos-sess a “nature” that can be grasped through intuition; they are separated from each other by continua in color space; there are an infinite number of a priori relations between colors. Second, I confront the geometrical approach with Wittgenstein’s grammatical approach, contending that the latter escapes these difficulties. [less ▲]

In the first novel written by Valeria Luiselli, Los ingrávidos (2011, translation in English: Faces in the crowd), the prominence of Gilberto Owen as a character indicates that Luiselli wishes to give a renewed visibility to this Mexican artist and, at the same time, to create a self-image that legitimates her activity as a writer. Disarticulated content, continuous intertextuality and recurring metaliterary reflection, various of the commonalities which link up Luiselli’s poetic practice with that of Owen suggest that she vindicates a literary relationship that situates her in a family of Mexican vanguard writers. This filiation is even more explicit in the novel, because Luiselli turns Owen into a literary character (not without exaggerating some of the poet’s traits that are often associated with the figure of the artist, such as alcoholism or relational failure) and introduces him as her own double.

Introduction: The ACP recently issued guidelines for the treatment of low bone density or osteoporosis to prevent fractures. Methods : Literature review and critical review of the ACP guidelines. Results :The guideline is lacking in scope due to the endorsement of treatment based on T-scores rather than fracture risk assessment and in failure to adequately consider anabolic therapies.

Objective: The primary aim of this study was to test whether differences in the ability of amnesic and healthy participants to detect alternative sources of fluency can account for differences observed in the use of fluency as a cue for memory. Method: Patients with severe memory deficits and matched controls were presented with three forced-choice recognition tests. In each test, an external source of fluency was provided by manipulating the perceptual quality of the studied items during the test phase. The detectability of the perceptual manipulation varied in each test (i.e., a 10%, 20%, or 30% contrast reduction were given). Results: The results indicated that all participants were able to rely on fluency when making recognition decisions as long as the perceptual manipulation remained unnoticed. Interestingly, our data also revealed that the level of contrast reduction at which the alternative source is detected differs between healthy controls and amnesic patients. Specifically, patients with amnesia appeared to disqualify fluency as a cue for memory even when the contrast reduction was moderate while healthy participants only disqualified fluency when the contrast reduction was clearly visible. Conclusion: Overall, our results seem to suggest that the ability to use fluency is probably not impaired in amnesia but undergo metacognitive changes resulting in the implementation of explicit or implicit strategies aiming at tracking alternative sources in order to reduce memory errors.

This paper studies an extended formulation of the Security Constrained Optimal Power Flow (SCOPF) problem, which explicitly takes into account the probabilities of contingency events and of potential failures in the operation of post-contingency corrective controls. To manage such threats, we express the requirement that the probability of maintaining all system operational limits, under any circumnstance, should remain acceptably high by means of a chance-constraint. Further, representing power flow as per the full AC model, we propose a heuristic solution approach leveraging state-of-the art methodologies and tools originally developed to tackle the standard, robust-constrained SCOPF statement. We exemplify the properties of our proposal by presenting its application on the three area version of the IEEE-RTS96 benchmark, stressing the interpretability of both the chance-constrained reliability management strategy and of the heuristic algorithm proposed to determine it. This work serves to showcase that the first step on the transition towards probabilistic reliability management can be achieved by suitably adapting presently available operational practices and tools.

Bacillus velezensisstrains, belonging to plant growth-promoting rhizobacteria (PGPR), areincreasingly used as microbial biostimulant. However, their field application to winter wheatunder temperate climate remains poorly documented. Therefore, threeB. velezensisstrainsIT45, FZB24 and FZB42 were tested for their efficacy under these conditions. Two biological in-teraction systems were firstly developed under gnotobiotic and greenhouse conditions combinedwith sterile or non-sterile soil, respectively, and finally assayed in the field during two yearscoupled with different N fertilization rates. Under gnotobiotic conditions, all three strains signifi-cantly increased root growth of 14 d-old spring and winter wheat seedlings. In the greenhouseusing non-sterile soil, only FZB24 significantly increased root biomass of spring wheat (+31%).The three strains were able to improve nutrient uptake of the spring wheat grown in the green-house, particularly for the micronutrients Fe, Mn, Zn, and Cu, but the observed increases innutrient uptake were dependent on the organs and the elements. The root biomass increases ininoculated plants coincided with lowered nutrient concentrations of P and K. In 2014, under fieldconditions and absence of any N fertilizer supply, FZB24 significantly increased grain yields by983 kg ha–1, or 14.9%, in relation to non-inoculated controls. The three strains in the 2015 fieldtrial failed to confirm the previous positive results, likely due to the low temperatures occurringduring and after inoculations. The Zeleny sedimentation value, indicative of flour quality, wasunaffected by the inoculants. The results are discussed in the perspective of bacterial applicationto wheat under temperate agricultural practices [less ▲]

Nappe oscillation is a phenomenon that can have an undesirable impact to the local environmental (e.g., nearby residences, parks) as the phenomenon has been observed to produce a significant level of noise caused by acoustic pressure waves. As a result, a detailed investigation was undertaken to identify practical and effective mitigation solutions to address these effects for free-overfall structures. Nappe oscillations were studied using a prototype-scale linear weir (weir length of 3.5 m and fall height of 3 m), a high-speed camera, and audio equipment. The effectiveness of various crest modifications to reduce nappe oscillation and any corresponding impacts to hydraulic efficiency were evaluated. The test matrix included the optimization (position and spacing of elements) of three mitigation solutions: 12 configurations with projecting elements, 5 configurations with deflectors and one configuration with a step. These three countermeasures proved to be effective after the optimization of their characteristics. In particular, deflectors or a step produced the maximum noise reduction while decreasing the discharge coefficient by less than 3 % over the range of experimental conditions. [less ▲]

Our study aimed at deepen our understanding of relationships between soil properties and vegetation distribution in metalliferous ecosystems of Tenke-Fungurume in the Democratic Republic of Congo. The first question concerned the differences and similarities between soils of the main vegetation units and four variation factors of soil properties were summarized by multivariate analysis. They were all linked to lithology and significantly contributed to explain the distribution of vegetation units. Our result suggest that the variation of soil properties which is observed within the various vegetation units (rocky steppe savanna, sward, and steppe savannas on slope or on Dembo) should partially be attributed to differences of geochemical composition of rocks between sites but the main source of variability is to be found inside each hill. The soil contamination in Cu and Co originates from rock weathering and besides site effect and topographic distribution of the rocks, the variability of soil properties within one vegetation unit may be due to variability of soil parent material and not only to erosion. The second question dealt with the changes of soil properties at small distances. Metric variation was studied from transects between adjacent vegetation units. Our results showed that the abrupt changes of vegetation units which were clearly identified on the field were all truly explained by the variations of one or more properties linked to lithology. The key point being the Cu bioavailability. [less ▲]

La démocratie reste un thème chéri par la philosophie politique contemporaine, pour l’écart entre ses théories et ses pratiques, pour la distance critique que ses théories offrent vis-à-vis des régimes démocratiques et de leur évolution, mais aussi parce qu’elle est un objet perpétuel de dissensus entre philosophes, au sujet duquel toute prétention à la véridiction est suspendue à sa réalisation pratique. À ce titre, la transmission de la volonté démocratique est un topos houleux de la philosophie politique contemporaine. Cette question catalyse les concepts pivots des philosophies politiques, la leur poser permet de mieux saisir les enjeux rivaux derrière une terminologie commune à plusieurs auteurs. C’est dans cette démarche que je vous propose d’examiner en miroir les philosophies de Cornélius Castoriadis et de Jacques Rancière. De plus en plus nombreux, des commentateurs rapprochent leurs pensées , qui peuvent s’appuyer sur plusieurs points communs : un attachement au concept de démocratie brandit contre les régimes parlementaires, une opposition contemporaine (quoique depuis des héritages différents) aux thèses défendues par Althusser, et une proximité de sources d’inspirations : la philosophie, le marxisme, et la psychanalyse. Partant de la manière dont cette proximité s’exprime dans la disjonction que chacun opère entre démocratie et science, je tenterai de discerner comment les inflexions qu’ils impriment aux concepts de volonté et d’égalité sous la guise des enjeux de la transmission dessinent des horizons politiques distincts, et dénotent des compréhensions antithétiques – mais indécidables dans la théorie – de ce que peut être la démocratie.

Dans l’une de ses conversations avec Joachim Gasquet sur le sens de sa peinture (et de la peinture en général), Cézanne aborde de front la conception qu’il se fait de la couleur, dans son rapport à la profondeur picturale et de son articulation à la surface : « La nature n'est pas en surface ; elle est en profondeur. Les couleurs sont l'expression, à cette surface, de cette profondeur. Elles montent des racines du monde ». Cet « organisme de couleurs » que constitue le monde est transcrit dans la peinture de Cézanne par une dynamique symbiotique de la couleur et du dessin, de la ligne et du pan. La couleur restitue, par sa masse, son surgissement, son homogénéité, presque sa viscosité, la véritable chaire perceptive du monde ; une vision qui tient à distance la perspective géométrique, photographique, cinématographique fondée sur la transparence et qui repose, comme le signale Merleau-Ponty, sur la « réversibilité des dimensions » (surface-profondeur) et l’entrelacement des choses. C’est cette épaisseur du visible rendu par la couleur que l’économie de l’image numérique nous permet de redécouvrir, moins dans le registre de la « tactilité » de l’image et la picturalité du pixel, que par l’intégration, entre le support et l’image (parfois indiscernables dans le régime optique), d’un « corps » algorithmique qui règle l’actualisation du visible. Certains défauts techniques du dispositif numérique, aujourd’hui élevés au rang de pratique artistique, permettent de révéler cette matrice qui utilise alors la couleur et la coulure comme mode de visibilité. C’est le cas du Datamoshing, technique de composition numérique qui revisite tout en la radicalisant la pratique de l’incrustation vidéo. Basée sur la perturbation volontaire d’éléments de la matrice, cette technique transforme les couleurs en une forme malléable et fluide révélant ainsi leur double nature spatiale : elles sont à la fois dans l’espace de l’image et l’espace de l’image lui-même. Ces expériences de défigurations d’images s’inscrivent dans le registre des « aberrations chromatiques » dont nous proposons ici une rapide généalogie avant d’interroger la couleur digitale dans ses spécificités.

The first mirrors of optical diagnostics in ITER are exposed to high radiation and fluxes of particles which escape the plasma, in the order of 10 20 m −2 s −1 . At the position of the mirror, the flux may still reach about 10 18 m −2 s −1 . First mirrors are thus the most vulnerable in-vessel optical components, being subject to erosion, esp. by fast charge-exchange neutrals, or to deposition of impurities at flux rates which can reach 0.05 nm/s. The material selected for the reflecting surface must combine a high optical reflectivity in a wide spectral range and a sufficient resistance to physical sputtering during normal operation and during mirror cleaning discharges, if any is installed. Rhodium ( 103 Rh) was identified early as a possible or even promising candidate. It combines several attractive properties, for instance a mass which leads in most cases to low sputtering yields together with an optical reflectance (R Rh ≈75%) which is much higher than of some other options. R Rh is insensitive to large temperature changes. Rhodium is fairly inert and its low oxidation is an appreciable advantage in case of steam ingress events. The core-plasma CXRS diagnostic in ITER (UPP 3) have now turned to Rh as a baseline. The aim is to procure monocrystalline rhodium (SC-Rh) to mitigate the increase of the diffuse reflection with the damage due to physical sputtering. © 2019 Elsevier B.V. [less ▲]

Co-production of water and sanitation services, especially in the global South, implies that recipients of a service play a fundamental role in managing water resources. In the context of citizen–government synergies, service recipients are more than consumers, and (co)-production alters their involvement in the service production process, with respect to their relationships with both the natural resources and the delivery process. Our hypothesis is that a meaningful understanding of co- production for water and sanitation services is only possible through an interdisciplinary approach that takes into account natural and social dimensions. The objective is to develop a possible new conceptualization of service co-production that can foster a renewed citizenship while taking into account the risks of urban fragmentation. [less ▲]

This study aims to investigate shifts in methane (CH4) emission in cattle in relation to the time after feeding, diet composition, and feed allowance. Four non-cannulated dry Holstein cows were equipped with activity and infrared sensors to monitor feeding behavior and CH4 and carbon dioxide (CO2) levels in the breath, continuously and at a frequency of 4 Hz. The second goal pursued, was to assess the methane emission estimation (CH4, L/h) by the CO2-method based on the ratio between CH4 and CO2 in the exhaled air, using metabolic CO2 as a marker. All cows were fed twice a day at 12 h intervals with contrasting isoenergy diets in a cross-over design: LIN100 diet (5562 VEM, i.e. Voedereenheid Melk, Dutch energy unit for milk production, 1 VEM = 6.9 kJ net energy for lactation) composed of haylage, linseed and wheat, and HAY100 (5367 VEM) diet containing only haylage. After a 2 week adaptation period to the diets, 3 days were required for the measurements and immediately after, two additional experimental treatments were applied by reducing the feed allowance to 70% with the same diets to evaluate the impact of the dry matter intake, yielding the two additional treatments HAY70 and LIN70. In addition, two other rumen-cannulated cows were used to monitor time after feeding short-chain fatty acid concentrations in the rumen. On a daily basis, all indicators (daily CH4:CO2 ratio, eructation frequency and CH4 emission) followed the same trend and showed that cows on a hay-based diet produced more CH4 and feed restriction induced different production levels for the same type of diet. The average CH4 emission for the different diets were 6.86 L/h for HAY100 > 6.25 L/h for HAY70 > 4.26 L/h for LIN100 > 3.97 L/h LIN70 (P < 0.001). The LIN100 diet produced 38% lower daily CH4 emissions than HAY100 and reduced the eructation frequency by 44%. During feeding, the eructation frequency was higher (P<0.001) for HAY than LIN diets. This work underlines the daily CH4 emission dynamics observed using the CH4:CO2 ratio in the cow's exhaled air. Methane emissions (L/h) are strongly influenced by the time after feeding time (P < 0.001). They increased for up to 2 hours after the distribution of the meal, and then decreased until the next meal, with shifts between the maximum and the minimum emission of more than 100% for LIN100 and 22% for HAY100. Consistently, the acetate:proprionate ratio was smaller for the LIN100 diet between 2 to 5 hours after the meal (P < 0.001). [less ▲]

Several studies have recently documented projects of organizational transformation and modernization which, commonly clustered under the umbrella term “New Ways of Working” (NWoW), simultaneously entail material, technological, cultural and managerial dimensions. Academic contributions, however, have paid little attention to the mechanisms allowing such projects to progressively become legitimized in organizational discourses and practices. The paper aims to investigate the distinctive features of the legitimation process underlying the implementation of NWoW projects. [less ▲]

This paper seeks to shed light on the diversity of scaling strategies of social enterprises, which can be considered as emblematic hybrid organizations. By comparing three Flemish renewable energy cooperatives with contrasted scaling strategies, the paper shows how these strategies can be understood in relation to the organizational mission as imprinted at the founding. We extend the notion of hybridity beyond the combination of institutional logics to highlight the interest orientation (mutual versus general interest). Unlike what is suggested in extant literature, we find that mutual interest orientation may be associated with ‘scale up’, business growth strategies, while general interest orientation may lead to less growth-focused ‘scale out’ and ‘scale deep’ strategies. The findings illuminate aspects of the hybrid nature of social enterprises by explaining their diverse scaling strategies, and extend the notion of imprinting to the inter-organizational level by highlighting how social enterprises may collaborate to collectively achieve the pursuit of their multiple missions.

Summary: This network meta-analysis assessed the efficacy of abaloparatide versus other treatment options to reduce the risk of fractures in women with postmenopausal osteoporosis. The analysis indicates that abaloparatide reduces the risk of fractures in women with postmenopausal osteoporosis versus placebo and compared with other treatment options. Introduction: This network meta-analysis (NMA) assessed the relative efficacy of abaloparatide versus other treatments to reduce the risk of fractures in women with postmenopausal osteoporosis (PMO). Methods: PubMed®, Embase®, and the Cochrane Central Register of Controlled Trials were searched for randomized controlled trials published before December 20, 2017, that included women with PMO who were eligible to receive interventions for primary or secondary fracture prevention. The NMA was conducted by fracture site (vertebral [VF], nonvertebral [NVF], and wrist), with the relative risk (RR) of fracture versus placebo the main clinical endpoint. The NMA used fixed-effects and random-effects approaches. Results: A total of 4978 articles were screened, of which 22 were included in the analysis. Compared with other treatments, abaloparatide demonstrated the greatest treatment effect relative to placebo in the VF network (RR = 0.13; 95% credible interval [CrI] 0.04–0.34), the NVF network (RR = 0.50; 95% CrI 0.28–0.85), and the wrist fracture network (RR = 0.39; CrI 0.15–0.90). Treatment ranking showed that abaloparatide had the highest estimated probability of preventing fractures in each of the networks (79% for VF, 70% for NVF, and 53% for wrist fracture) compared with other treatments. Individual networks demonstrated a good level of agreement with direct trial evidence and direct pair-wise comparisons. Conclusions: This NMA indicates that abaloparatide reduces the RR of VF, NVF, and wrist fracture in women with PMO with or without prior fracture versus placebo, compared with other treatment options. Limitations include that adverse events and drug costs were not considered, and that generalizability is limited to the trial populations and endpoints included in the NMA. © 2019, The Author(s).

In eukaryotes, membrane contact sites (MCS) allow direct communication between organelles. Plants have evolved a unique type of MCS, inside intercellular pores, the plasmodesmata, where endoplasmic reticulum (ER) - plasma membrane (PM) contacts coincide with regulation of cell-to-cell signalling. The molecular mechanism and function of membrane tethering within plasmodesmata remains unknown. Here we show that the Multiple C2 domains and Transmembrane region Protein (MCTP) family, key regulators of cell-to-cell signalling in plants, act as ER-PM tethers specifically at plasmodesmata. We report that MCTPs are core plasmodesmata proteins that insert into the ER via their transmembrane region whilst their C2 domains dock to the PM through interaction with anionic phospholipids. A Atmctp3/Atmctp4 loss-of-function mutant induces plant developmental defects while MCTP4 expression in a yeast Δtether mutant partially restores ER-PM tethering. Our data suggest that MCTPs are unique membrane tethers controlling both ER-PM contacts and cell-to-cell signalling. [less ▲]

In the Kerguelen Islands, the multiple effects of climate change are expected to impact coastal marine habitats. Species distribution models (SDM) can represent a convenient tool to predict the biogeographic response of species to climate change but biotic interactions are not considered in these models. Nevertheless, new species interactions can emerge in communities exposed to environmental changes and the structure of biotic interactions is directly related to the potential resilience of ecosystems. Trophic interaction studies can help predict species vulnerability to environmental changes using carbon (δ13C) and nitrogen (δ15N) stable isotope ratios to generate trophic models. Using new available data inputs, we generated robust SDM and trophic interaction models to assess the potential response and sensitivity of three echinoid species to future worst-case scenarios of environmental change in the Kerguelen Plateau region. The two modelling approaches provide contrasting insights into the potential responses of each species to future environmental changes with both approaches identifying Abatus cordatus to be particularly vulnerable due to its narrow ecological niche and endemism to near-shore areas. Coupling insights gained from trophic niche ecology with species distribution modelling represents a promising approach that can improve our understanding and ability to predict the potential responses of species to future habitat changes.

Abstract: There are discrepancies in the reports on the association of metabolic syndrome (MetS) and its components with bone mineral density (BMD) and hence more population-based studies on this subject are needed. In this context, this observational study was aimed to investigate the association between T-scores of BMD at lumbar L1–L4 and full MetS and its individual components. A total of 1587 participants (84.7% females), >35 years and with risk factors associated with bone loss were recruited from February 2013 to August 2016. BMD was done at L1–L4 using dual-energy X-ray absorptiometry (DXA). T-Scores were calculated. Fasting blood samples and anthropometrics were done at recruitment. Fasting lipid profile and glucose were measured. Screening for full MetS and its components was done according to the National Cholesterol Education Programme Adult Treatment Panel III (NCEP ATP III) criteria. Logistic regression analysis revealed that the odds of having full MetS increased significantly from the lowest T-score tertile to the highest one in both sexes (OR, odd ratio (95% CI, confidence interval) of tertile 2 and 3 at 1.49 (0.8 to 2.8) and 2.46 (1.3 to 4.7), p = 0.02 in males and 1.35 (1.0 to 1.7) and 1.45 (1.1 to1.9), p < 0.01 in females). The odds remained significant even after adjustments with age, body mass index (BMI), and other risk factors associated with bone loss. Among the components of MetS, only central obesity showed a significant positive association with T-score. The study suggests a significant positive association of T-score (spine) with full MetS irrespective of sex, and among the components of MetS this positive association was seen specifically with central obesity.

This article explores how rural Malawians used an NGO’s presence to negotiate their changing intra-community responsibilities. It responds to a perceived incompatibility between development and kinship-inspired moral economies by exploring how “becoming developed” became a (contested) way to fulfil intra-communal obligations and entitlements, which were previously enacted through resource sharing. It also shows how villagers’ understanding that donors were a patron for their entire community encouraged them to make demands on the NGO’s project’s beneficiaries. These findings should persuade practitioners to consider how their projects will be reinterpreted through community-embedded concepts of obligation and the effects of their mere presence on local meanings of development.

Resolving population genetic structure is challenging, especially when dealing with closely related populations. Although Principal Component Analysis (PCA)-based methods and genomic var- iation with single nucleotide polymorphisms (SNPs) are widely used to describe shared genetic an- cestry, improvements can be made targeting fine-level population structure. This work presents an R package called IPCAPS, which uses SNP information for resolving possibly fine-level population structure. The IPCAPS routines are built on the iterative pruning Principal Component Analysis (ipP- CA) framework to systematically assign individuals to genetically similar subgroups. Our tool is able to detect and eliminate outliers in each iteration to avoid misclassification. It can be extended to de- tect subtle subgrouping in patients as well. In addition, IPCAPS supports different measurement scales for variables used to identify substructure. Hence, panels of gene expression and methylation data can be accommodated. [less ▲]

Aims of the study - The first aim of this study was to set a battery of field tests in order to assess specific muscular function of biketrial riders. The second aim was to investigate the discrimination of these tests by comparing the performance of elite and amateur riders. Material and method - Twenty ELITE biketrial riders and 13 biketrial amateurs (AMAT) underwent field tests. The battery of field tests consisted in four non specific jumping tests (SJ, CMJ,SBJ and Reactivity) and three original specific tests on the bike (bike gap, side-hop over an elastic and holding time on the back-wheel). All the tests were performed on the field with portable equipment. Results – The results show that bike specific tests are very discriminant: ELITE riders were significantly superior in each test (p<0.001) The 20in riders seem to have a greater jumping ability in comparison with the 24in riders. The correlation between the jumping field tests and the bike specific tests is fairly high (r>0.7). Conclusion – The field tests as well as the bike specific tests showed to be selective and discriminant for the biketrial rider’s. Jumping ability appears to be very important in order to achieve the elite level. [less ▲]

The discovery that mutations of the CYP24A1 gene are a cause of idiopathic infantile hypercalcemia (IIH) has revived interest in measuring serum 24,25(OH)2D3. Several studies have also suggested that a high 25-hydroxyvitamin D3(25-OHD3):24,25(OH)2D3 ratio might provide additional diagnostic information in the investigation of vitamin D deficiency. Measurement of 24,25(OH)2D3 is necessarily restricted to laboratories with mass spectrometry methods although cross reactivity of the metabolite in immunoassays for 25-OHD is a potential cause of misleading results. The international External Quality Assessment (EQA) scheme for vitamin D metabolites (DEQAS) was set up in 1989. In 2013 DEQAS became an accuracy based EQA for 25-OHD with 'target values' assigned by the National Institute of Standards and Technology (NIST) Reference Measurement Procedure (RMP). A pilot scheme for serum 24,25(OH)2D3 was started in 2015 and participants were asked to measure the metabolite on each of the 5 samples sent out for 25-OHD. Inter-laboratory agreement was poor but this may reflect methodological differences, in particular different approaches to assay standardization. An important potential contribution to reducing variability among assays was the development by NIST of a 24,25(OH)2D3 RMP and its use in assigning values to SRMs 972a, 2973 and 2971, supported by the NIH Office of Dietary Supplements (ODS) as part of the Vitamin D Standardization Program (VDSP) effort.

BACKGROUND:Considerable differences exist among the living donor Kidney Exchange Programmes (KEPs) that are in use and being built in Europe, contributing to a variation in the number of living donor transplants [6]. Efforts of European KEPs to exchange (best) practices and share approaches to address challenges have, however, been limited.METHODS:Experts from 23 European countries, collaborating on the ENCKEP COST Action, developed a questionnaire to collect detailed information on the functioning of all existing KEPs in Europe, as well as their opportunities and challenges. Following a comparative analysis, results were synthesised and interpreted by the same experts.RESULTS:The practices, opportunities and challenges reported by 17 European countries reveal that some of the 10 operating programmes are mature, while others are in earlier stages of development. Over 1300 transplants were performed through existing KEPs up to the end of 2016, providing approximately 8\% of their countries' living kidney donations in 2015. All countries report challenges to either initiating KEPs or increasing volumes. Some challenges are shared, whilst others differ because of differences in context (eg, country size, effectiveness of deceased donor programme) and ethical and legal considerations (eg, regarding living donation as such, nonrelated donors, and altruistic donation). Transnational initiatives have started in Central Europe, Scandinavia, and Southern Europe.CONCLUSIONS:Exchange of best practices and shared advancement of national programmes to address existing challenges, aided by transnational exchanges, may substantially improve access to the most (cost) effective treatment for the increasing number of patients suffering from kidney disease.This is an open access article distributed under the Creative Commons Attribution License 4.0 (CCBY), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.
