Non-negligible amounts of Distributed Generating Units (DGUs) are already connected to power systems, predominantly to medium- and low-voltage networks. The interaction between distribution and transmission systems is gaining the attention of system operators. Given the high controlability of DGUs, the active distribution networks can potentially support the transmission system during emergency situations. Previously proposed voltage emergency controls involving distribution network assets focused on preserving the transmission system integrity, even if it implies affecting the distribution system operation (intrusive schemes). More attention needs to be devoted to supporting transmission voltages, while preserving the distribution network operation (non-intrusive schemes). This paper introduces a new adaptive and non-intrusive voltage emergency control scheme based on the synchronization of DGUs and the load tap changer of the corresponding distribution transformer. The conclusions are derived from time-domain simulations using an extended version of the IEEE Nordic test system for voltage stability assessment. [less ▲]

As in many European countries, Belgium has faced since 2015 the arrival of migrants marked by extreme vulnerability. Their reception has led European societies to shape polarized opinions around the migratory issue and it has triggered large debates on the management of migration through a securitization approach, as well as on the humanitarian responses to it. In this context, Belgium has witnessed the appearance of a number of citizens’ initiatives wishing to supplement the failings (perceived or real) of reception and integration institutions. Constructed and structured around the humanitarian aid to be provided to migrants, these initiatives contribute to the emergence of relational dynamics (and demands) that go beyond the “simple” response to primary needs and trigger political positions and claims. Based on two case studies mainly engaging migrants coming from African countries, this article brings a micro-analysis of the processes through which the relations within humanitarian action contribute to the redefinition of the goals of these citizens’ movements, bringing political objectives into an action originally focused on an ethical register. Our analysis also addresses the spaces and forms of speaking up by migrants within these dynamics, and the process of their politicization. [less ▲]

This paper explores the relatively new phenomenon of citizen participation in the Smart City context. We present a case study comparative analysis of three participatory approaches implemented in three European Smart Cities. Each of those operational perspectives is studied in view of the theoretical concepts conveyed by the scientific state of the art, this way highlighting similarities and gaps between theory and practice. The results are focused on (i) the various existing interpretations of the “citizen participation” and the “Smart City” definitions, on (ii) the different selection processes applied in all three cases to recruit the participating citizens and on (iii) the benefits and drawbacks associated with the implementation of participative processes in a Smart City. The article closes with a discussion about key elements to keep in mind when implementing a bottom-up participative approach in the context of a Smart City. Eventually, the confrontation between theoretical and practical perspectives results in a revisited version of Arstein’s ladder of citizen participation, adapted to the Smart City context. [less ▲]

Background. After a period of coma, a proportion of individuals with severe brain injury remain in an altered state of consciousness before regaining partial or complete recovery. Individuals with disorders of consciousness (DOC) classically receive hydration and nutrition through an enteral feeding tube. However, the real impact of the level of consciousness on an individual’s swallowing ability remains poorly investigated. Objective. We aimed to document the incidence and characteristics of dysphagia in DOC individuals and to evaluate the link between different components of swallowing and the level of consciousness. Methods. We analyzed clinical data on the respiratory status, oral feeding and otolaryngologic examination of swallowing in DOC individuals. Univariate and multivariate logistic regression was used to analyse the association of components of swallowing and participant groups (i.e., unresponsive wakefulness syndrome [UWS] and minimally conscious state [MCS]). Results. We included 92 individuals with DOC (26 UWS and 66 MCS). Overall, 99% of the participants showed deficits in the oral and/or pharyngeal phase of swallowing. As compared with the MCS group, the UWS group more frequently had a tracheostomy (69% vs 24%), with diminished cough reflex (27% vs 54%) and no effective oral phase (0% vs 21%). Conclusion. Almost all DOC participants had severe dysphagia. Some components of swallowing (i.e., tracheostomy, cough reflex and efficacy of the oral phase of swallowing) were related to consciousness. In particular, no UWS participant had an efficient oral phase, which suggests that its presence may be a sign of consciousness. In addition, no UWS participant could be fed entirely orally, whereas no MCS participant orally received ordinary food. Our study also confirms that objective swallowing assessment can be successfully completed in DOC individuals and that specific care is needed to treat severe dysphagia in DOC. [less ▲]

Over the period 2015-2017, the five giant technologically leading firms, Google, Amazon, Facebook, Apple and Microsoft (GAFAM) acquired 175 companies, from small startups to billion dollar deals. In this paper, we provide detailed information and statistics on the merger activity of the GAFAM and on the characteristics of the firms they acquire. One of the most intriguing features of these acquisitions is that, in the majority of cases, the product of the target is discontinued under its original brand name post acquisition and this is especially true for the youngest firms. There are three reasons to discontinue a product post acquisition: the product is not as successful as expected, the acquisition was not motivated by the product itself but by the target's assets or R\&D effort, or by the elimination of a potential competitive threat. While our data does not enable us to screen between these explanations, the present analysis shows that most of the startups are killed in their infancy. This important phenomenon calls for tighter intervention by competition authorities in merger cases involving big techs. [less ▲]

Poly(oxazolidone) is an emerging class of polyur- ethanes (PUs) that is easily accessible by an isocyanate-free pathway via the step-growth copolymerization of CO2-based monomers (bis(α-alkylidene cyclic carbonate)s) with primary diamines at room temperature. Here, we explore the scope and limitation of this process by investigating the influence of the diamine and the reaction conditions on the structure and macromolecular parameters of the polymer. Less hindered diamines (aliphatic and benzylic) provide selectively poly- (hydroxyoxazolidone)s, whereas the bulkier ones (cycloaliphatic) furnish polymer chains bearing two types of linkages, oxo- urethane and hydroxyoxazolidone ones. The increase of the reaction temperature or the addition of DBU as a catalyst enables to accelerate the polymerizations. The quantitative polymer dehydration is also achieved by refluxing in acetic acid, providing a new class of unsaturated poly(oxazolidone)s composed of α-alkylidene oxazolidone linkages (for hindered polymers) or a mixture of α- and β-alkylidene oxazolidone linkages (for the less hindered ones). These unsaturated poly(oxazolidone)s present a high glass transition temperature (90 °C ≤ Tg ≤ 130 °C) and a remarkable thermal stability (Td > 360 °C), rendering these polymers attractive for applications requiring high temperatures. This work is therefore opening an avenue to novel functional isocyanate-free PUs, with the pendant hydroxyl or olefin groups that are expected to be easily derivatized. [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.

Je donnerai différents arguments en analysant ces débats (historiques, méthodologiques et cliniques) afin de proposer une lecture singulière des pathologies de la liberté et de voir comment cette lecture s’inscrit dans le champ psychopathologique. L’objectif de ma contribution sera de rencontrer le vécu en première personne du sujet psychotique qui se retrouve mal dans la qualification de son existence comme étant privée de liberté. Comme le titre de cette étude l’annonce, la thèse que je défends est de considérer que l’interrogation des pathologies de la liberté conduit également à interroger son corollaire, la dimension inéluctablement libre inhérente aux personnes affectées de psychopathologies. Ce décalage, que nous permettra d’entrevoir Lacan, nous mènera à interroger la dimension adaptative de l’expérience psychopathologique et, dans la continuité de Canguilhem, à considérer la pathologie comme la création de normes inédites (généralement inaccessibles à autrui).

This paper advocates for a progressive rethinking of the day-ahead/intra-day power system security management practice in the low-carbon energy transition era. As a starting point, the need for multi-TSO coordination in order to efficiently exploit the value of grid flexibility towards operating the low-carbon, multi-area power system securely and economically is established. On this basis, the core proposal of this paper is the adoption of a new approach to day-ahead/intra-day multi-area power system security management, inspired from the principles of cooperative game theory. The proposed approach relies on counterfactual analysis to evaluate the (positive and/or negative) impact of each distinctive control-area to the common security of the multi-area system, thus providing clear economic incentives to achieve the required coordination. This proposal is not a marginal approach and notably facilitates the integration of more detailed physical modeling (including the non-convexities of the power system) in the inter-TSO settlement of the multi-area interconnected system security management cost. The proposed framework allows some level of subsidiarity and the definition of hedging products to cover ex-post costs. Further from the blueprint of the proposed approach, the paper discusses prominent research and development pathways in order to progressively put such vision into practice. [less ▲]

The goal of this commentary is to highlight the ageism that has emerged during the COVID-19 pandemic. Over 20 international researchers in the field of aging have contributed to this document. This commentary discusses how older people are misrepresented and undervalued in the current public discourse surrounding the pandemic. It points to issues in documenting the deaths of older adults, the lack of preparation for such a crisis in long term care homes, how some “protective” policies can be considered patronizing and how the initial perception of the public was that the virus was really an older adult problem. This commentary also calls attention to important intergenerational solidarity that has occurred during this crisis to ensure support and social-inclusion of older adults, even at a distance. Our hope is that with this commentary we can contribute to the discourse on older adults during this pandemic and diminish the ageist attitudes that have circulated. [less ▲]

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.

Generalized additive models (GAMs) are a well-established statistical tool for modeling complex nonlinear relationships between covariates and a response assumed to have a conditional distribution in the exponential family. To make inference in this model class, a fast and flexible approach is considered based on Bayesian P-splines and the Laplace approximation. The proposed Laplace-P-spline model contributes to the development of a new methodology to explore the posterior penalty space by considering a deterministic grid-based strategy or a Markov chain sampler, depending on the number of smooth additive terms in the predictor. The approach has the merit of relying on a simple Gaussian approximation to the conditional posterior of latent variables with closed form analytical expressions available for the gradient and Hessian of the approximate posterior penalty vector. This enables to construct accurate posterior pointwise and credible set estimators for (functions of) regression and spline parameters at a relatively low computational budget even for a large number of smooth additive components. The performance of the Laplace-P-spline model is confirmed through different simulation scenarios and the method is illustrated on two real datasets. [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.

While age differences in episodic memory are well documented, the impact of age on the structure of memories for real-world events has not been investigated in detail. Recent research has shown that the continuous flow of information that constitutes daily life events is compressed in episodic memory, such that the time needed to mentally replay an event is shorter than the actual event duration. To examine whether this process of temporal compression of prior experience in episodic memory is affected by aging, we asked young and older adults to engage in a series of events that simulated daily life activities while their experience was automatically recorded using a wearable camera. Subsequently, participants were asked to mentally replay these events in as much detail as possible and then to verbally report recalled contents and to rate the subjective qualities of their memories. Results revealed that the rates of temporal compression of events during mental replay were similar in young and older adults. In both age groups, rates of temporal compression were predicted by the density of recalled moments of prior experience per unit of time of the actual event duration. Interestingly, however, the number of recalled moments predicted the subjective vividness of memories in young but not in older adults. Taken together, these results suggest that the process of temporal compression of events in episodic memory is unaffected by age but that the subjective experience of memory vividness becomes less tied to recalled moments that represent the unfolding of events.

Background: Odanacatib, a cathepsin K inhibitor, reduces bone resorption while maintaining bone formation. Previous work has shown that odanacatib increases bone mineral density in postmenopausal women with low bone mass. We aimed to investigate the efficacy and safety of odanacatib to reduce fracture risk in postmenopausal women with osteoporosis. Methods: The Long-term Odanacatib Fracture Trial (LOFT) was a multicentre, randomised, double-blind, placebocontrolled, event-driven study at 388 outpatient clinics in 40 countries. Eligible participants were women aged at least 65 years who were postmenopausal for 5 years or more, with a femoral neck or total hip bone mineral density T-score between –2·5 and –4·0 if no previous radiographic vertebral fracture, or between –1·5 and –4·0 with a previous vertebral fracture. Women with a previous hip fracture, more than one vertebral fracture, or a T-score of less than –4·0 at the total hip or femoral neck were not eligible unless they were unable or unwilling to use approved osteoporosis treatment. Participants were randomly assigned (1:1) to either oral odanacatib (50 mg once per week) or matching placebo. Randomisation was done using an interactive voice recognition system after stratification for previous radiographic vertebral fracture, and treatment was masked to study participants, investigators and their staff, and sponsor personnel. If the study completed before 5 years of double-blind treatment, consenting participants could enrol in a double-blind extension study (LOFT Extension), continuing their original treatment assignment for up to 5 years from randomisation. Primary endpoints were incidence of vertebral fractures as assessed using radiographs collected at baseline, 6 and 12 months, yearly, and at final study visit in participants for whom evaluable radiograph images were available at baseline and at least one other timepoint, and hip and non-vertebral fractures adjudicated as being a result of osteoporosis as assessed by clinical history and radiograph. Safety was assessed in participants who received at least one dose of study drug. The adjudicated cardiovascular safety endpoints were a composite of cardiovascular death, myocardial infarction, or stroke, and new-onset atrial fibrillation or flutter. Individual cardiovascular endpoints and death were also assessed. LOFT and LOFT Extension are registered with ClinicalTrials.gov (number NCT00529373) and the European Clinical Trials Database (EudraCT number 2007-002693-66). Findings: Between Sept 14, 2007, and Nov 17, 2009, we randomly assigned 16 071 evaluable patients to treatment: 8043 to odanacatib and 8028 to placebo. After a median follow-up of 36·5 months (IQR 34·43–40·15) 4297 women assigned to odanacatib and 3960 assigned to placebo enrolled in LOFT Extension (total median follow-up 47·6 months, IQR 35·45–60·06). In LOFT, cumulative incidence of primary outcomes for odanacatib versus placebo were: radiographic vertebral fractures 3·7% (251/6770) versus 7·8% (542/6910), hazard ratio (HR) 0·46, 95% CI 0·40–0·53; hip fractures 0·8% (65/8043) versus 1·6% (125/8028), 0·53, 0·39–0·71; non-vertebral fractures 5·1% (412/8043) versus 6·7% (541/8028), 0·77, 0·68–0·87; all p<0·0001. Combined results from LOFT plus LOFT Extension for cumulative incidence of primary outcomes for odanacatib versus placebo were: radiographic vertebral fractures 4·9% (341/6909) versus 9·6% (675/7011), HR 0·48, 95% CI 0·42–0·55; hip fractures 1·1% (86/8043) versus 2·0% (162/8028), 0·52, 0·40–0·67; non-vertebral fractures 6·4% (512/8043) versus 8·4% (675/8028), 0·74, 0·66–0·83; all p<0·0001. In LOFT, the composite cardiovascular endpoint of cardiovascular death, myocardial infarction, or stroke occurred in 273 (3·4%) of 8043 patients in the odanacatib group versus 245 (3·1%) of 8028 in the placebo group (HR 1·12, 95% CI 0·95–1·34; p=0·18). New-onset atrial fibrillation or flutter occurred in 112 (1·4%) of 8043 patients in the odanacatib group versus 96 (1·2%) of 8028 in the placebo group (HR 1·18, 0·90–1·55; p=0·24). Odanacatib was associated with an increased risk of stroke (1·7% [136/8043] vs 1·3% [104/8028], HR 1·32, 1·02–1·70; p=0·034), but not myocardial infarction (0·7% [60/8043] vs 0·9% [74/8028], HR 0·82, 0·58–1·15; p=0·26). The HR for all-cause mortality was 1·13 (5·0% [401/8043] vs 4·4% [356/8028], 0·98–1·30; p=0·10).When data from LOFT Extension were included, the composite of cardiovascular death, myocardial infarction, or stroke occurred in significantly more patients in the odanacatib group than in the placebo group (401 [5·0%] of 8043 vs 343 [4·3%] of 8028, HR 1·17, 1·02–1·36; p=0·029, as did stroke (2·3% [187/8043] vs 1·7% [137/8028], HR 1·37, 1·10–1·71; p=0·0051). Interpretation: Odanacatib reduced the risk of fracture, but was associated with an increased risk of cardiovascular events, specifically stroke, in postmenopausal women with osteoporosis. Based on the overall balance between benefit and risk, the study’s sponsor decided that they would no longer pursue development of odanacatib for treatment of osteoporosis. [less ▲]

BACKGROUND. Articulating design and ergonomics skills through education is a major challenge for both fields. Indeed, professional ergonomists are more and more deeply involved in design processes, and ergonomics education should train them in design skills. As courses in ergonomics education are often time-constrained, it is difficult to engage students in real-scale projects and to plunge them into design processes. Conversely, activity analysis and active involvement of users in design projects (through co-creation or co-design processes) are rarely convened in architecture and design curricula. OBJECTIVE. It is therefore necessary to develop effective and relevant pedagogical settings, enabling students of both fields to develop their abilities and equip them to take action in concrete design situations. METHODS. In this paper, we describe a large-scale pedagogical setting involving groups of students from different disciplines gathered around a real-scale design project (re-shaping the waiting room of a mental health centre). Ergonomics students’ main task is to analyse the needs and real activities of end-users; interior design students’ task is to produce the design project. This communication more precisely focuses on describing the ergonomics students’ fieldwork and the practical and pedagogical innovations put in place to help them face the various challenges encountered during the project. RESULTS Based on formal feedback from students, teachers and stakeholders, we address three main challenges (1) dealing with the temporal constraints of the intervention, (2) documenting and observing a sensitive situation and (3) involving end-users to put them at the core of the design process. For each challenge, we describe the issue at stake; the work conducted to deal with this issue and eventually the feedback collected from students, teachers and stakeholders. CONCLUSION. The paper concludes with an analysis of success and failure factors for such pedagogical settings. In particular, physical enquiry devices, co-creation processes and co-constructed pedagogical settings are reviewed and paths for further improvement are opened, thanks to the collected feedback.

AIMS: The aim of this study was to evaluate the two-year outcomes of the One Tooth-One Time (1T1T) completely digital workflow, allowing the immediate loading of a single implant in the posterior region with a final CAD-CAM crown made of a polymer-infiltrated ceramic network (PICN). MATERIALS AND METHODS: A series of 10 implants were placed, and an intra-oral scan was taken after the surgery. A final screw-retained PICN crown was manufactured chair-side and placed the same day in full occlusion. Marginal peri-implant bone changes and soft-tissue health were evaluated, as well as restoration performance using World Dental Federation criteria and Pink and White Esthetic Scores. Patient-related outcome measures (PROMs) and time consumption data were collected. RESULTS: After two years, the implant survival rate was 100%. The debonding of one crown from its Titanium Base led to a 90% prosthodontic survival rate and the remaining crowns were all considered successful. The mean marginal peri-implant bone changes yielded 0.87 (SD: 0.96) and 0.55 (SD: 0.53) mm after one and two years, respectively. Mild or no inflammation of peri-implant soft tissue was observed in most implants. The overall treatment time reached 175 min and PROMs displayed high patient satisfaction. CONCLUSIONS: This study constitutes the first report considering immediate loading of a single implant in the posterior region with a final crown in occlusion. In this case-series, the two-year outcomes of the 1T1T protocol seem rather promising and fulfil patient expectations. However, those preliminary results need to be confirmed by randomized control trials and patient selection is probably a key factor in this procedure success. [less ▲]

We aimed to evaluate the effect of different grazing management strategies on carcass characteristics traits, meat quality and CH4 intensity and yield of lambs grazing Italian ryegrass pastures in Southern Brazil. A grazing trial was performed (2014 and 2015) in a randomized complete block design with two grazing management targets and four replicates. Treatments were traditional rotational stocking (RT), with pre- and post-grazing sward heights of 25 and 5 cm, respectively, and ‘Rotatinuous’ stocking (RN), with pre- and post-grazing sward heights of 18 and 11 cm, respectively. Castrated crossbred Texel and Polwarth lambs were used. Results indicated that diet cost per kg of dry matter (p = 0.001) and per hectare (p < 0.001) were lower for RN than for RT treatment. Final live weight (p = 0.022) and hot and cold carcass weight (p = 0.006) were greater for the RN treatment. All commercial cuts were greater for RN than for RT treatment. The RN treatment presented greater (p < 0.001) production of carcass, edible food and crude protein. Feed efficiency and feed cost conversion were better for RN than for RT treatment. CH4 intensity per kg of carcass, edible food and crude protein gain were 2.6, 2.7 and 2.1 times lower (p < 0.001) for RN. Moreover, CH4 yield was lower (p = 0.014) for RN than for RT treatment, with an average of 7.6 and 8.3% of the gross energy intake, respectively. We conclude that the ‘Rotatinuous’ stocking results in a greater carcass production, carcass quality and lower diet cost, and CH4 intensity and yield of grazing lambs. Adopting this grazing management strategy could enhance both lamb production and mitigation of CH4 intensity and yield in grazing ecosystems, which could be considered a good example of climate-smart livestock production.

As part of a project on Content and Language Integrated Learning (CLIL) in French-speaking Belgium, this study aims to explore the impact of formal and informal input on learners’ variability in writing, and to compare two target-language conditions (Dutch and English) in CLIL and non-CLIL settings in French-speaking Belgium. A regression model shows that CLIL is a significant predictor of L2 outcomes for both target languages, but that the relative impact of formal and informal input differs depending on the target language. In short, the amount of formal language exposure predicts the outcomes of the written productions of the learners of English, and the frequency of informal exposure those of the learners of Dutch. We argue that this observation is likely related to the difference in status that each of these languages holds among the pupils in our sample. The findings thus highlight the importance of the L2 status in research on CLIL, since different L2s can yield different results. [less ▲]

Regional connectivity-based parcellation (rCBP) is a widely used procedure for investigating the structural and functional differentiation within a region of interest (ROI) based on its long-range connectivity. No standardized software or guidelines currently exist for applying rCBP, making the method only accessible to those who develop their own tools. As such, there exists a discrepancy between the laboratories applying the procedure each with their own software solutions, making it difficult to compare and interpret the results. Here, we outline an rCBP procedure accompanied by an open source software package called CBPtools. CBPtools is a Python (version 3.5+) package that allows users to run an extensively evaluated rCBP analysis workflow on a given ROI. It currently supports two modalities: resting-state functional connectivity and structural connectivity based on diffusion-weighted imaging, along with support for custom connectivity matrices. Analysis parameters are customizable and the workflow can be scaled to a large number of subjects using a parallel processing environment. Parcellation results with corresponding validity metrics are provided as textual and graphical output. Thus, CBPtools provides a simple plug-and-play, yet customizable way to conduct rCBP analyses. By providing an open-source software we hope to promote reproducible and comparable rCBP analyses and, importantly, make the rCBP procedure readily available. Here, we demonstrate the utility of CBPtools using a voluminous data set on an average compute-cluster infrastructure by performing rCBP on three ROIs prominently featured in parcellation literature.

Young people’s romantic relationships can be marked with various forms of dating violence (DV). However, adolescents and emerging adults do not necessarily acknowledge this violence because of their attitudes toward dating violence. Our study aims to study dating violence and attitudes toward this phenomenon through two well-established questionnaires administered jointly in their entirety. Indeed, too many studies report results on some dimensions and items, neglecting the richness of available tools. The Conflict in Adolescent Dating Relationship Inventory and the Attitudes Toward Dating Violence Scale were self-administered to 1,014 participants (M age = 18.9) attending secondary schools or a regional college. They reported the frequency of their dating violence perpetration and victimization, and their attitudes toward dating violence. Results show that relational and sexual violence perpetration rates are higher for males, physical violence perpetration rate is higher for females, and relational violence victimization is higher for males. MANCOVAs not only show the same trends for scores but also underline more frequent emotional violence perpetrated by females, physical victimization for males, and sexual victimization for females. Males show higher tolerance toward every form of dating violence; younger participants are also more tolerant. Participants are more tolerant toward male-perpetrated psychological DV than femaleperpetrated ones, and more tolerant toward female-perpetrated physical and sexual DV compared with male-perpetrated physical and sexual DV. There are patterns of multiperpetration, multivictimization, bidirectionality, and multi(in)tolerance. Our paper contributes to the symmetry debate, a better understanding of the link between attitudes and violent behaviors, a further step on gendered attitudes regarding who perpetrates and who sustains.

Background: The Global Leadership Initiative on Malnutrition (GLIM) criteria have been recently launched by consensus of the major nutrition societies. GLIM criteria are partly constructed on the previous definition of malnutrition developed by the European Society of Clinical Nutrition and Metabolism (ESPEN). We aimed to assess malnutrition according to the ESPEN and GLIM criteria at baseline and to determine the corresponding risk of mortality during a 4-year follow-up in community-dwelling older adults from the SarcoPhAge (Sarcopenia and Physical Impairment with advancing Age) study. The relationship between malnutrition and incidence of 4-year adverse health consequences (institutionalization, hospitalization, falls, and fractures) was assessed. Methods: This prospective population-based cohort was part of SarcoPhAge, which included 534 older adults in Belgium, followed up from 2013 to 2019. Community-dwelling healthy volunteers ≥65 years old were recruited. Mortality and adverse health consequences were collected annually by interview or phone call. Baseline malnutrition was defined according to the GLIM and ESPEN criteria. Agreement between the two definitions was reported by Cohen's kappa coefficient. Adjusted Cox regression and Kaplan–Meier survival curves were performed for malnutrition. Logistic regression was used for the other outcomes. Results: From 534 subjects in SarcoPhAge, the records for 411 participants (73.2 ± 6.05 years old; 55.7% women) had all the variables needed to apply the GLIM criteria. Prevalence of baseline malnutrition was 23.4% for GLIM and 7% for ESPEN criteria (k = 0.30, low agreement). The adjusted Cox regression showed a significant increased mortality risk according to malnutrition status as defined by the GLIM [adjusted hazard ratio = 4.41 (95% confidence interval: 2.17–8.97)] and ESPEN [adjusted hazard ratio = 2.76 (95% confidence interval: 1.16–6.58)] criteria. Survival curves differed significantly between malnourished and non-malnourished groups, regardless of the definition used (log rank P < 0.001 for both). No association was found between baseline malnutrition according to these two criteria and 4-year risk of institutionalization, hospitalization, falls, or fractures (all P > 0.05). Conclusions: Malnutrition according to the GLIM criteria was associated with a 4.4-fold higher mortality risk, double that of the ESPEN criteria, during a 4-year follow-up. No association was found between malnutrition according to these two criteria and incidence of other health adverse consequences. GLIM criteria anticipate mortality and might guide interventions, with important implications for clinical practice and research. © 2020 The Authors.

Determining the lipid content and fatty acid (FA) composition of aquatic organisms has been of major interest in trophic ecology, aquaculture, and nutrition for over half a century. Although protocols for lipid analysis are well-described, their application to aquatic sciences often requires modifications to adapt to field conditions and to sample type. Here, we present the current state of knowledge of methods dedicated to both marine and freshwater lipid analyses, from sampling to data treatment. We review: (i) sample preservation, storage and transport protocols, and their effects on lipids, (ii) lipid extraction, separation of polar and neutral lipids, derivatization, and detection methods, and (iii) available tools for the statistical analysis of FA data. We provide recommendations for best practices in field situations and advocate for protocol standardization and interlaboratory calibration. [less ▲]

The breadth of emerging case studies and empirical evidence linking slow onset events and human mobility (migration and displacement) is difficult to succinctly summarize, owing to the wide range of slow onset hazards, their impacts, their varied interactions with other drivers of population movement, and the specificity of local contexts. Nevertheless, the growing literature demonstrates that the effects of slow onset processes interact with social, political, economic, environmental, and demographic factors to drive both human migration and displacement. One of the major impacts of slow onset events evident in the literature is the disruption of local livelihoods, particularly for those people dependent on natural resources, e.g. farmers, fishers, and pastoralists. Commonly, this underpins empirical case studies related to economic, more ‘voluntary’ migration patterns, yet these events may also contribute to displacement by decreasing ecosystem services and overwhelming populations’ capacity to withstand both slow- and rapid-onset events. The combination of these impacts can lead local communities to reach climatic and social tipping points, at which the socio-ecological capacity to cope in situ is exceeded, leading to displacement. This synthesis article, therefore, distinguishes between displacement and more voluntary forms of migration in slow onset contexts related to climate change, while acknowledging that a clear distinction between migration and displacement is often blurred in the context of slow-onset events such as sea-level rise, desertification and land and forest degradation. It recognizes that slow-onset events may in many situations interact or exacerbate rapid-onset events in multi-risk scenarios, increasing the risk of loss and damage. The article assesses the state of knowledge on human mobility related to slow onset events by distilling academic and ‘grey’ literature across geographical regions, with particular attention given to developing country contexts. It will draw from various secondary and bibliographic resources including the CLIMIG database. This contribution identifies commonalities as well as gaps and tensions in the field at different spatial scales, in order to provide scientific information that can support and inform national planning and policymaking processes in assessing and addressing the mobility impacts and risks associated with slow onset events.

Objectives: Impairments of metacognitive skills represent a critical symptom in Alzheimer Disease (AD) because it frequently results in a lack of self-awareness. However, recent findings suggest that, despite an inability to explicitly estimate their own cognitive functioning, patients might demonstrate some implicit recognition of difficulties. In this study, we tested whether a behavioral dissociation between explicit and implicit measures of metacognition can be found in both healthy older controls (n = 20) and AD patients (n = 20). Methods: Our two groups of participants (AD vs. Controls) were asked to complete a forced-choice perceptual identification test and to explicitly rate their confidence in each decision (i.e., explicit measure of metacognition). Moreover, they also had the opportunity to ask for a cue to help them decide if their response was correct (i.e., implicit measure of metacognition). Results: Data revealed that all participants asked for a cue more often after an incorrect response than after a correct response in the forced-choice identification test, indicating a good ability to implicitly introspect on the results of their cognitive operations. On the contrary, only healthy participants displayed metacognitive sensitivity when making explicit confidence judgments. Conclusion: Our findings suggest that implicit metacognition may be less affected than explicit metacognition in Alzheimer’s disease. [less ▲]

This paper presents a methodology to derive a reduced-order, “grey-box” model of an active distribution network. This dynamic equivalent is intended for dynamic simulations of large disturbances taking place in the transmission system. To deal with the uncertainty affecting dynamic model parameters, Monte-Carlo simulations are used, and the parameters of the equivalent are adjusted to match as close as possible the average randomized system responses. To avoid over-fitting, multiple disturbances are considered; they are automatically selected among a set of candidates. Moreover, to reduce the computational burden, only parameters with significant impact are adjusted in the identification procedure. Simulation results are reported on a real Australian distribution grid. The latter hosts synchronous generators and residential photovoltaic units. Its loads are modelled with a static and a motor part. [less ▲]

The purpose of this article is to study sense of parental competence in parents who experienced abuse in childhood. Many studies have shown that the kind of abuse (physical, emotional, sexual, neglect) that the parent experienced in childhood and the co-occurrence of several types of abuse affect the sense of parental competence. In particular, we focused on the difference between sexual abuse and other kinds of abuse. The instruments used to collect data were the French versions of the Childhood Trauma Questionnaire, which assesses abuse, and the Parenting Sense of Competence Scale, which assesses efficacy and satisfaction. These questionnaires were designed to quantitatively evaluate the kind of abuse experienced during childhood and the sense of parental competence. We collected 828 valid protocols. The statistical analyses show that sense of parental competence is lower in parents who were abused during their childhood than in those who were not. More specifically, our results show that these parents feel less satisfaction, one of the two components of the sense of parental competence. [less ▲]

Dating violence (DV) is a serious social problem among adolescents and emerging adults, both boys and girls are victims and perpetrators. The current study aimed to investigate correlates of dating violence perpetration among Belgian youths. We examined facets of empathy and verbal skills as protective factors, and facets of impulsivity as risk factors for psychological and physical DV perpetration. Eight hundred and thirteen adolescents and emerging adults (71.7% females, Mean Age=18.9) completed self-administered questionnaires investigating their physical and psychological DV perpetration, empathy, verbal skills and impulsivity. Findings show that male and female respondents have different patterns of correlations between the studied variables. Facets of empathy and verbal skills hinder DV perpetration, whereas facets of impulsivity foster it. The impact of the different facets can vary across regression models, gender of the perpetrator and forms of DV. The present study contributes to a better understanding of DV by examining facets of empathy, verbal skills and impulsivity. Prevention programs are encouraged to target specific facets of these variables among adolescents and emerging adults. [less ▲]

This paper investigates universal and areal structures in the lexicon as manifested by colexification patterns in the semantic domains of perception and cognition, based on data from both small and large datasets. Using several methods, including weighted semantic maps, formal concept lattices, correlation analysis, and dimensionality reduction, we identify colexification patterns in the domains in question and evaluate the extent to which these patterns are specific to particular areas. This paper contributes to the methodology of investi-gating areal patterns in the lexicon, and identifies a number of cross-linguistic regularities and of area-specific properties in the structuring of lexicons.

Inhibitory control underlies the ability to inhibit inappropriate responses and involves processes that suppress motor excitability. Such motor modulatory effect has been largely described during action preparation but very little is known about the neural circuit responsible for its implementation. Here, we addressed this point by studying the degree to which the extent of preparatory suppression relates to brain morphometry. We investigated this relationship in patients suffering from severe alcohol use disorder (AUD) because this population displays an inconsistent level of preparatory suppression and major structural brain damage, making it a suitable sample to measure such link. To do so, 45 detoxified patients underwent a structural magnetic resonance imaging (MRI) and performed a transcranial magnetic stimulation (TMS) experiment, in which the degree of preparatory suppression was quantified. Besides, behavioral inhibition and trait impulsivity were evaluated in all participants. Overall, whole-brain analyses revealed that a weaker preparatory suppression was associated with a decrease in cortical thickness of a medial prefrontal cluster, encompassing parts of the anterior cingulate cortex and superior-frontal gyrus. In addition, a negative association was observed between the thickness of the supplementary area (SMA)/pre-SMA and behavioral inhibition abilities. Finally, we did not find any significant correlation between preparatory suppression, behavioral inhibition and trait impulsivity, indicating that they represent different facets of inhibitory control. Altogether, the current study provides important insight on the neural regions underlying preparatory suppression and allows highlighting that the excitability of the motor system represents a valuable read-out of upstream cognitive processes.

Study of the relation between urban density and social equity has been mostly based upon comparative analysis at the city level. It therefore fails to address variations in intra-urban experience and sheds no light on the process of urban densification. Incremental residential development is particularly poorly recorded and underre-searched, yet cumulatively it makes a substantial contribution to the supply of dwellings. The paper presents a detailed examination of this form of development in England between 2001 and 2011 and considers its impact on urban spatial justice. We find that the incidence of soft residential densification was very uneven. It had disproportionately large effects on neighbourhoods that were already densely developed and that were characterized by lower income households with access to relatively little residential space. It thus contributed to an increase in the level of inequality in the distribution of residential space, increasing socio-spatial injustice. [less ▲]

Purpose There has been much debate regarding the use of intra-articular injections of platelet-rich plasma (PRP) as symptomatic treatment for knee osteoarthritis. The objective of this consensus was to develop guidelines for PRP injections in knee osteoarthritis according to the French National Authority for Health recommendations. Methods Fifteen physicians from different French-speaking countries (10 rheumatologists, 4 specialists in rehabilitation and sports medicine and 1 radiologist) were selected for their expertise in the areas of PRP and osteoarthritis. A comprehensive literature review was conducted on Medline including all published therapeutic trials, open studies, meta-analysis and systematic reviews focusing on the effects of PRP in knee OA, as well as fundamental studies concerning the characteristics of the various types of PRP and their mechanisms, indexed before April 2019. Using the method recommended by the French National Authority for Health inspired by the Delphi consensus process, 25 recommendations were finally retained and evaluated. The recommendations were classified as appropriate or not appropriate, with strong or relative agreement, or uncertain if a consensus was not achieved. Results Among the 25 recommendations selected, the main ones are the following: (1) Intra-articular injections of PRP are an effective symptomatic treatment for early to moderate knee osteoarthritis. This recommendation was considered appropriate with a relative agreement (Median = 8; rank = 6–9). Level of evidence 1A. (2) A PRP treatment sequence in knee osteoarthritis may include 1–3 injections. This recommendation was considered appropriate with a strong agreement (Median = 9; rank = 7–9). Level of evidence 1A. (3) Leucocytes-poor PRP should be preferred in knee osteoarthritis. This recommendation was considered appropriate with a relative agreement (Median = 8; rank = 5–9). Level of evidence 5. (4) Intra-articular PRP knee injections should be performed under ultrasound or fluoroscopic guidance. This recommendation was considered uncertain with no consensus (Median = 8; rank = 3–9). Level of evidence 5. (5) PRP should not be mixed with an anesthetic or intra-articular corticosteroid. This recommendation was considered appropriate with a relative agreement (Median = 9; rank = 6–9). Level of evidence 5 Conclusion Those 25 recommendations should standardize and facilitate the use of IA PRP injections, which are considered by experts as an effective treatment especially in early or moderate knee OA. Although a strong or relative agreement from the experts was obtained for most of the recommendations, many of them had a very low level of evidence (Level 5) and were principally based on the clinical experience of the experts.

In this study, an efficient methodology, allowing the controlled co‐immobilization of two complementary biomolecules, is reported for the production of multifunctional antibacterial surfaces. To promote long‐lasting covalent immobilization, metallic surfaces are first coated with a quinone‐bearing poly(methacrylate)‐based thin film by combining an atmospheric pressure liquid‐assisted plasma polymerization and a controlled sodium periodate‐induced catechol oxidation steps. The influence of the oxidation step on the film morphology and chemistry is investigated using an analytical multitool approach involving atomic force microscopy, ultraviolet, infrared, and X‐ray photoelectron spectroscopy techniques. Quartz crystal microbalance with dissipation monitoring (QCM‐D) analyses allow the rapid determination of the optimal biomolecule immobilization conditions in terms of kinetics of grafting and biomolecule solution concentrations. In vitro functional assays combined with QCM‐D analyses demonstrate promising, dual biologically active coated surfaces. [less ▲]

Objectives Two major objectives are presented. Firstly, we aim at optimizing and validating a HS-SPME-GC-MS method for the quantification of 5 alkylfurans in chocolate. Secondly, we focus our study on measuring the quantitative impact of engraving technique on the formation of furan and its derivatives in chocolate, from the raw callets to processed end-products. Method HS-SPME-GC-MS method operating in SIM mode and using isotope dilution technique with deuterated homologue internal standards was used to quantify alkylfurans in chocolate. Results Good repeatability (RSD% = 0.1-8%, in duplicate) and intermediate precision (RSD% = 1.7-7%, n = 6) were obtained for these five process contaminants at 10, 25, and 50 µg/kg. Trueness was varying between 81 and 109%. LoQ ranged from 0.48 to 2.50 µg/kg. Relative expanded measurement uncertainties ranged from 6 to 30%. Finally, tempering is responsible for a 24% increase in furan contamination, while the laser engraving technique results in an additional 31% increase in furan. A similar trend was also observed for 2-methylfuran and 3-methylfuran, whereas no significant increases were observed for 2,3-dimethylfuran and 2,5-dimethylfuran. Conclusions and highlights A reliable and sensitive method of HS-SPME-GC-MS was reported for the first time for the analysis of furan and four alkylfurans in chocolate. This paper demonstrated that engraving using laser-based techniques can increase the levels of these compounds by up to 30%. [less ▲]

Thiamine precursors, the most studied being benfotiamine (BFT), have protective effects in mouse models of neurodegenerative diseases. BFT decreased oxidative stress and inflammation, two major characteristics of neurodegenerative diseases, in a neuroblastoma cell line (Neuro2a) and an immortalized brain microglial cell line (BV2). Here, we tested the potential antioxidant and anti-inflammatory effects of the hitherto unexplored derivative O,S-dibenzoylthiamine (DBT) in these two cell lines. We show that DBT protects Neuro2a cells against paraquat (PQ) toxicity by counteracting oxidative stress at low concentrations and increases the synthesis of reduced glutathione and NADPH in a Nrf2-independent manner. In BV2 cells activated by lipopolysaccharides (LPS), DBT significantly decreased inflammation by suppressing translocation of NF-κB to the nucleus. Our results also demonstrate the superiority of DBT over thiamine and other thiamine precursors, including BFT, in all of the in vitro models. Finally, we show that the chronic administration of DBT arrested motor dysfunction in FUS transgenic mice, a model of amyotrophic lateral sclerosis, and it reduced depressive-like behavior in a mouse model of ultrasound-induced stress in which it normalized oxidative stress marker levels in the brain. Together, our data suggest that DBT may have therapeutic potential for brain pathology associated with oxidative stress and inflammation by novel, coenzyme-independent mechanisms. [less ▲]

The Wingate Anaerobic Test (WAnT) and isokinetic fatigability protocols are mainly used to evaluate the anaerobic power of athletes for whom jumping is a predominant action in their sport. Nevertheless, the testing protocol must be as close as possible to the activity pattern of the sport to be valid. Therefore, for these athletes, the test should consist of repetitions of jumps that are task-specific. Our aim was to propose a new jumping protocol allowing for specific assessment of fatigue, to examine its absolute and relative reliability and to determine its ideal duration. Twenty male volleyball performed fifty countermovement jumps (CMJ) at a rate of 33 jumps per minute on two occasions, with seven days recovery between each session. Jump height was computed for each CMJ using a 3D optoelectronic system, which was subsequently added to determine cumulative performance after 10, 15, 20, 25, 30, 35, 40, 45 and 50 repetitions. Reliability of the average jump height was not affected by the lengthening of the protocol and was high for all considered durations (ICC > 0.94; SEM < 5%). A decrease in performance was directly and proportionally related to the duration of the fatigability protocol. Measuring average jump height during a protocol involving 25 CMJ at the rate of 33 jumps per minute appears to represent the best compromise between reliability, induced fatigue and physiological considerations. Moreover, until 25 repetitions, the partial sums by five repetitions can and should be used to further explore the subject's performance during the test. [less ▲]

Purpose: The aim of this study was to investigate children’s processing of dysphonic speech in a realistic classroom setting, under the influence of added classroom noise. Method: Normally developing 6-year-old primary-school children performed two listening tasks in their regular classrooms: a phoneme discrimination task to assess speech perception, and a sentence-picture matching task to assess listening comprehension. Speech stimuli were played back in either a normal or an impaired voice quality. Children performed the tasks in the presence of induced classroom noise at signal-to-noise ratios (SNR) between +2 and +9 dB. Results: Children’s performance in the phoneme discrimination task decreased significantly when the speaker’s voice was impaired. The effect of voice quality on sentence-picture matching depended on task demands: easy sentences were processed more accurately in the impaired-voice condition than in the normal-voice conditions. SNR effects are discussed in light of methodological constraints. Conclusions: Listening to a dysphonic teacher in a noisy classroom may impede children’s perception of speech, particularly when phonological discrimination is needed to disambiguate the speech input. Future research regarding the interaction of voice quality and task demands is necessary. [less ▲]

Aim: Large trees [≥ 70 cm diameter at breast height (DBH)] contribute disproportionately to aboveground carbon stock (AGC) across the tropics but may be vulnerable to changing climate and human activities. Here we determine the distribution, drivers and threats to large trees and high carbon forest. Location: Central Africa. Time period: Current. Major taxa studied: Trees. Methods: Using Gabon's new National Resource Inventory of 104 field sites, AGC was calculated from 67,466 trees from 578 species and 97 genera. Power and Michaelis–Menten models assessed the contribution of large trees to AGC. Environmental and anthropogenic drivers of AGC, large trees, and stand variables were modelled using Akaike’s information criterion (AIC) weights to calculate average regression coefficients for all p. ossible models. Results: Mean AGC for trees ≥ 10 cm DBH in Gabonese forestlands was 141.7 Mg C/ha, with averages of 166.6, 171.3 and 96.6 Mg C/ha in old growth, concession and secondary forest. High carbon forests occurred where large trees are most abundant: 31% of AGC was stored in large trees (2.3% of all stems). Human activities largely drove variation in AGC and large trees, but climate and edaphic conditions also determined stand variables (basal area, tree height, wood density, stem density). AGC and large trees increased with distance from human settlements; AGC was 40% lower in secondary than primary and concession forests and 33% higher in protected than non-managed areas. Main conclusions: AGC and large trees were negatively associated with human activities, highlighting the importance of forest management. Redefining large trees as ≥ 50 cm DBH (4.3% more stems) would account for 20% more AGC. This study demonstrates that protecting relatively undisturbed forests can be disproportionately effective in conserving carbon and suggests that including sustainable forestry in programs like reduced emissions for deforestation and forest degradation could maintain carbon dense forests in logging concessions that are a large proportion of remaining Central African forests. © 2020 John Wiley & Sons Ltd [less ▲]

In the North Sea, sympatric grey and harbour seals may compete for food resources impacted by intense fishing activities and a recent increase of seal populations. In order to reduce inter-specific competition, sympatric species must segregate at least one aspect of their ecological niches: temporal, spatial or resource segregation. Using isotopes and Se and Hg concentrations, the foraging resources of grey seals and harbour seals and the potential competition between these species in the North Sea was studied. δ13C, δ15N and δ34S values were combined with the concentrations of Hg and Se in blood samples of harbour and grey seals from the North Sea. Blood samples were collected on 45 grey seals and 37 harbour seals sampled along German and Scottish coasts. This multi-tracer approach showed spatial and resource partitioning within grey and harbour seals. Data indicated the offshore foraging distribution of grey seals as reflected by the lower δ15N values and T-Hg concentrations and higher Se concentrations, and the inshore foraging distribution of harbour seals because of higher δ15N values and T-Hg concentrations and lower Se concentrations. The SIAR mixing model revealed a more selective diet of grey seals compared to harbour seals, and the importance of sandeels in grey seal diet reflected by their high δ34S values. Lastly, diet ellipse overlaps between grey seals and harbour seals sampled along the German coasts suggested a potential sharing of food resources, possibly due to the increase number of grey seals number in this area during the foraging season - all year except breeding and moulting periods. The multi-tracer approach provided a more robust discrimination among diet resources and spatial foraging distributions of grey seals and harbour seals in the North Sea. [less ▲]

We provide an evidence base and guidance for the use of menopausal hormone therapy (MHT) for the maintenance of skeletal health and prevention of future fractures in recently menopausal women. Despite controversy over associated side effects, which has limited its use in recent decades, the potential role for MHT soon after menopause in the management of postmenopausal osteoporosis is increasingly recognized. We present a narrative review of the benefits versus risks of using MHT in the management of postmenopausal osteoporosis. Current literature suggests robust anti-fracture efficacy of MHT in patients unselected for low BMD, regardless of concomitant use with progestogens, but with limited evidence of persisting skeletal benefits following cessation of therapy. Side effects include cardiovascular events, thromboembolic disease, stroke and breast cancer, but the benefit-risk profile differs according to the use of opposed versus unopposed oestrogens, type of oestrogen/progestogen, dose and route of delivery and, for cardiovascular events, timing of MHT use. Overall, the benefit-risk profile supports MHT treatment in women who have recently (< 10 years) become menopausal, who have menopausal symptoms and who are less than 60 years old, with a low baseline risk for adverse events. MHT should be considered as an option for the maintenance of skeletal health in women, specifically as an additional benefit in the context of treatment of menopausal symptoms, when commenced at the menopause, or shortly thereafter, in the context of a personalized benefit-risk evaluation. © 2020, The Author(s).

Summary: Cost-effectiveness analysis of FRAX® intervention thresholds (ITs) in Singaporean women > 50 years of age showed that generic alendronate was cost-effective at age-dependent major osteoporotic fracture (MOF) IT from the ages of 65 years for both full and real-world adherence whilst hip fracture (HF) ITs were cost-effective from the ages of 60 and 65 years. Alendronate was cost-effective irrespective of age only at fixed MOF IT of 14% and HF IT of 3.5%. Introduction: FRAX®-based intervention thresholds (ITs) were recently identified for osteoporosis management in Singapore. This study aimed to assess the cost-effectiveness of ITs in Singaporean women over the age of 50 years. Methods: A validated Markov microsimulation model was used to estimate the lifetime healthcare costs (SGD2019) per quality-adjusted life-years (QALY) of generic alendronate compared with no treatment. Cost-effectiveness of age-dependent FRAX® major osteoporotic fracture (MOF) and hip fracture (HF) ITs was explored. In addition, ITs that would lead to cost-effectiveness were computed. Fracture incidence and cost data were obtained from the Ministry of Health and a previously published Singaporean study. A cost-effectiveness threshold of SGD 62,500/QALY gained was used, based conservatively on 0.7 times the Singapore GDP per capita. Results: Generic alendronate was shown to be cost-effective at MOF ITs from the ages of 65 years, while HF ITs were cost-effective from the ages of 60 and 65 years, assuming full and real-world adherence, respectively. A 14% MOF and a 3.5% HF ITs were required for alendronate to be cost-effective above 50 years. Conclusion: This study suggests that the treatment of Singaporean women with alendronate is cost-effective at age-dependant FRAX® intervention thresholds at 65 years and older. Furthermore, identifying women at any age above 50 years with a 10-year risk of MOF or HF of 14% or 3.5% would lead to efficient use of resources. Cost-effective access to therapy for patients at high fracture probability based on FRAX® could contribute to reduce the growing burden of osteoporotic fractures in Singapore. © 2020, The Author(s).

In this article, we explain the link between Pohlen's extended Hadamard product and the holomorphic cohomological convolution on C^*. For this purpose, we introduce a generalized Hadamard product, which is defined even if the holomorphic functions do not vanish at infinity, as well as a notion of strongly convolvable sets.

Whilst the links between learner corpus research (LCR) and Second Language Acquisition (SLA) have long been debated, McEnery et al. (2019, 17) claim that the promise made by Granger in 2009 that learner corpora would “soon be accepted as a bona fide data type in SLA research” has yet to be realized. This article aims to go one way towards realizing this promise by illustrating the benefits of collecting and analyzing data sets that better document multiliteracy practices. We first contextualize our work within the field of LCR where calls for more multidimensional data sets have been made. We then present a new database called MulTINCo – Multilingual Traditional, Immersion, and Native Corpus – collected within the context of a large-scale project on Content and Language Integrated Learning (CLIL) in French-speaking Belgium. As our data set contains rich metadata and blends corpus data with other data types, we explain how it can help bridge the LCR/SLA gap. In Sections 3 and 4, we describe the data collected and the interface. In the last section of the paper, we wrap up the discussion on the methodological assets of such multidimensional data sets for SLA studies, and present outlooks on future research. [less ▲]

We present a spectroscopic survey of 230 white dwarf candidates within 40 pc of the Sun from the William Herschel Telescope and Gran Telescopio Canarias. All candidates were selected from $\textit{Gaia}$ Data Release 2 (DR2) and in almost all cases had no prior spectroscopic classifications. We find a total of 191 confirmed white dwarfs and 39 main-sequence star contaminants. The majority of stellar remnants in the sample are relatively cool ($\langle T_{\rm eff} \rangle$ = 6200 K), showing either hydrogen Balmer lines or a featureless spectrum, corresponding to 89 DA and 76 DC white dwarfs, respectively. We also recover two DBA white dwarfs and 9--10 magnetic remnants. We find two carbon-bearing DQ stars and 14 new metal-rich white dwarfs. This includes the possible detection of the first ultra-cool white dwarf with metal lines. We describe three DZ stars for which we find at least four different metal species, including one which is strongly Fe- and Ni- rich, indicative of the accretion of a planetesimal with core-Earth composition. We find one extremely massive (1.31 $\pm$ 0.01 M$_{\odot}$) DA white dwarf showing weak Balmer lines, possibly indicating stellar magnetism. Another white dwarf shows strong Balmer line emission but no infrared excess, suggesting a low-mass sub-stellar companion. High spectroscopic completeness ($>$99%) has now been reached for $\textit{Gaia}$ DR2 sources within 40 pc sample, in the northern hemisphere ($\delta >$ 0 deg) and located on the white dwarf cooling track in the Hertzsprung-Russell diagram. A statistical study of the full northern sample is presented in a companion paper. [less ▲]

This paper addresses one question: What makes detective series popular today? In the past, scholars have responded that the genre is mainly focused on plot, to the point of becoming a narrative prototype. This approach explains why detective fiction appears to be more limited in its proliferation across media than other genres such as fantasy or science fiction. If plot is the dominant feature of the genre, and plot somehow works against proliferation, then why are we still producing and consuming so many detective series? Following Marie-Laure Ryan, I wish to argue that a shift from plot to worldbuilding has occurred in detective fiction. This shift follows the evolution of narrative theory which in the last decades had to expand to other disciplines and media. In the same way that narratology embraced the new concept of 'world,' popular series have adopted its potential to proliferate, an aptitude that is now truly part of its aesthetics and poetics. I want to describe and understand the increasingly important role played by storyworlds in detective fiction so as to better apprehend how popular series are made in our cultural era of mass media production.

Methods and technologies enabling the estimation at large scale of important traits for the dairy sector are of great interest. Those phenotypes are necessary to improve herd management, animal genetic evaluation, and milk quality control. In the recent years, the research was very active to predict new phenotypes from the mid-infrared (MIR) analysis of milk. Models were developed to predict phenotypes such as fine milk composition, milk technological properties or traits related to cow health, fertility and environmental impact. Most of models were developed within research contexts and often not designed for routine use. The implementation of models at a large scale to predict new traits of interest brings new challenges as the factors influencing the robustness of models are poorly documented. The first objective of this work is to highlight the impact on prediction accuracy of factors such as the variability of the spectral and reference data, the spectral regions used and the complexity of models. The second objective is to emphasize methods and indicators to evaluate the quality of models and the quality of predictions generated under routine conditions. The last objective is to outline the issues and the solutions linked with the use and transfer of models on large number of instruments. Based on partial least square regression and 10 datasets including milk MIR spectra and reference quantitative values for 57 traits of interest, the impact of the different factors is illustrated by evaluating the influence on the validation root mean square error of prediction (RMSEP). In the displayed examples, all factors, when well set up, increase the quality of predictions, with an improvement of the RMSEP ranging from 12% to 43%. This work also aims to underline the need for and the complementarity between different validation procedures, statistical parameters and quality assurance methods. Finally, when using and transferring models, the impact of the spectral standardization on the prediction reproducibility is highlighted with an improvement up to 86% with the tested models, and the monitoring of individual spectrometer stability over time appears essential. This list inspired from our experience is of course not exhaustive. The displayed results are only examples and not general rules and other aspects play a role in the quality of final predictions. However, this work highlights good practices, methods and indicators to increase and evaluate quality of phenotypes predicted at a large scale. The results obtained argue for the development of guidelines at international levels, as well as international collaborations in order to constitute large and robust datasets and enable the use of models in routine conditions.
