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 ▲]

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 ▲]

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 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 ▲]

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 ▲]

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.

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 ▲]

Objective To quantify whole‐brain functional organization after complete hemispherotomy, characterizing unexplored plasticity pathways and the conscious level of the dissected hemispheres. Methods Evaluation with multimodal magnetic resonance imaging in two pediatric patients undergoing right hemispherotomy including complete callosotomy with a perithalamic section. Regional cerebral blood flow and fMRI network connectivity assessed the functional integrity of both hemispheres after surgery. The level of consciousness was tested by means of a support vector machine classifier which compared the intrinsic organization of the dissected hemispheres with those of patients suffering from disorders of consciousness. Results After hemispherotomy, both patients showed typical daily functionality. We found no interhemispheric transfer of functional connectivity in either patient as predicted by the operation. The healthy left hemispheres displayed focal blood hyperperfusion in motor and limbic areas, with preserved network‐level organization. Unexpectedly, the disconnected right hemispheres showed sustained network organization despite low regional cerebral blood flow. Subcortically, functional connectivity was increased in the left thalamo‐cortical loop and between the cerebelli. One patient further showed unusual ipsilateral right cerebello‐cortical connectivity, which was explained by the mediation of the vascular system. The healthy left hemisphere had higher probability to be classified as in a minimally conscious state compared to the isolated right hemisphere. Significance Complete hemispherotomy leads to a lateralized whole‐brain organization, with the remaining hemisphere claiming most of the brain's energetic reserves supported by subcortical structures. Our results further underline the contribution of nonneuronal vascular signals on contralateral connectivity, shedding light on the nature of network organization in the isolated tissue. The disconnected hemisphere is characterized by a level of consciousness which is necessary but insufficient for conscious processing, paving the way for more specific inquiries about its role in awareness in the absence of behavioral output.

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 ▲]

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.

Through an examination of the sessions of the congress, the accompanying exhibition and the drafting of the charter that was one of its outcomes, it questions the views of experts of the time on the reconstruction of archaeological sites. The result is a contrasted landscape in terms of projects and principles and the observation of a certain unresolved uneasiness in the face of a practice which, after the second reconstruction, is justified, to the great regret of a part of the profession, by the development of the tourism economy.

In this study, we investigated the ability of children with developmental language disorder (DLD) to extend nouns referring to different categories of novel objects. In a word extension task, we used several types of object entities (solid, animate, non-solid, functional and spatial relations) for which children had to attend to diverse properties (either shape, or texture, or role, or spatial relation) to decide category membership. We compared 15 school-aged children with DLD to typically developing (TD) children matched on either age or vocabulary. Our results indicate that children with DLD were impaired extending novel words for non-solid substances and relational objects, whereas age-matched TD children performed well for all object classes. Similar to children with DLD, TD children matched on language had difficulty extending spatial relation categories. We also show that children with DLD needed more learning exemplars and relied more on shape-based information than TD children did, especially for spatial configuration objects.

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.

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).

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 ▲]

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 ▲]

• The presence of acrylamide (AA), a potentially carcinogenic and neurotoxic compound, in food has become a major concern for public health. AA in plant-derived food mainly arises from the reaction of the amino acid asparagine (Asn) and reducing sugars during processing of foodstuffs at high temperature. • Using a selection of genotypes from the chicory (Cichorium intybus L.) germplasm we performed Asn measurements in storage roots and leaves to identify genotypes contrasting for Asn accumulation. We combined molecular analysis and grafting experiments to show that leaf to root translocation controls asparagine biosynthesis and accumulation in chicory storage roots. • We could demonstrate that Asn accumulation in storage roots depends on Asn biosynthesis and transport from the leaf, and that a negative feedback loop by Asn on CiASN1 expression impacts Asn biosynthesis in leaves. • Our results provide a new model for asparagine biosynthesis in root crop species and highlight the importance of characterizing and manipulating asparagine transport to reduce AA content in processed plant-based foodstuffs.

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.

BACKGROUND: Locked-in syndrome (LIS) characterizes individuals who have experienced pontine lesions, who have limited motor output but with preserved cognitive abilities. Despite their severe physical impairment, individuals with LIS self-profess a higher quality of life than generally expected. Such third-person expectations about LIS are shaped by personal and cultural factors in western countries. OBJECTIVE: We sought to investigate whether such opinions are further influenced by the cultural background in East Asia. We surveyed attitudes about the ethics of life-sustaining treatment in LIS in a cohort of medical and non-medical Chinese participants. RESULTS: The final study sample included 1545 respondents: medical professionals (n=597, 39%), neurologists (n=303, 20%), legal professionals (n=276, 18%) and other professionals (n=369, 24%), including 180 family members of individuals with LIS. Most of the participants (70%), especially neurologists, thought that life-sustaining treatment could not be stopped in individuals with LIS. It might be unnecessary to withdraw life-sustaining treatment, because the condition involved is not terminal and irreversible, and physical treatment can be beneficial for the patient. A significant proportion (59%) of respondents would like to be kept alive if they were in that condition; however, older people thought the opposite. Families experience the stress of caring for individuals with LIS. The mean (SD) quality of life score for relatives was 0.73 (2.889) (on a -5,+5 scale), which was significantly lower than that of non-relatives, 1.75 (1.969) (P<0.001). CONCLUSIONS: Differences in opinions about end of life in LIS are affected by personal characteristics. The current survey did not identify a dissociation between personal preferences and general opinions, potentially because of a social uniformity in China where individualism is less pronounced. Future open-ended surveys could identify specific needs of caregivers so that strategic interventions to reduce ethical debasement are designed. [less ▲]

This article looks into the issue of autonomy, often portrayed as a key feature of modern work arrangements, in particular of Independent professionals (IPros). Given the absence of conclusive evidence in the current debate opposing structural and agency views on autonomy at work, we study how Ipros perform their job referring to three main analytical dimensions: formalization, verticality and openness. Our empirical material is composed of critical incidents reported by 37 executive coaches working in France. We show that IPros’ autonomy unfolds over a 3-phase process combining the three aforementioned dimensions of autonomy that we associate with power strategies. This combination therefore reflects a complex interaction between structural and agentic factors, paving the way for a political process perspective on autonomy. Therefore, our paper advocates combining rather than opposing structural and agentic views on autonomy, and also expands the traditional agentic view of IPros’ autonomy beyond the dominant psychological argument.

This study examines the contribution of the psychological contract (PC) framework to the understanding of ethnic minority employees’ employment relationships. First, it tests the generalizability of PC types (transactional, relational, and balanced) observed in the general population to ethnic minority employees. Then, to further address the unique needs and motivators of minority employees, this study considers diversity-related PCs. It adopts social exchange theory to explain how transactional, relational, balanced, and diversity-related PC breaches predict organizational citizenship behavior (OCB). Moreover, it draws insights from social identity theory and examines the mediating role of organizational identification in the relationship between types of PC breach and OCB. Data from 361 Turkish employees working as ethnic minorities in Belgium indicate that relational and diversity-related PC breaches predict OCB partially via organizational identification while transactional and balanced PC breaches directly affect OCB.

This paper presents the results of a parametric study on the occupational exposure in interventional radiology to explore the influence of various variables on the staff doses. These variables include the angiography beam settings: x-ray peak voltage (kVp), added copper filtration, field diameter, beam projection and source to detector distance. The study was performed using Monte-Carlo simulations with MCNPX for more than 5600 combinations of parameters that account for different clinical situations. Additionally, the analysis of the results was performed using both multiple and random forest regression to build a predictive model and to quantify the importance of each variable when the variables simultaneously change. Primary and secondary projections were found to have the most effect on the scatter fraction that reaches the operator followed by the effect of changing the x-ray beam quality. The effect of changing the source to image intensifier distance had the lowest effect. [less ▲]

In many healthcare settings, benchmarking for complex procedures has become a mandatory requirement by competent authorities, regulators, payers and patients to assure clinical performance, cost-effectiveness and safe care of patients. In several countries inside and outside Europe, benchmarking systems have been established for haematopoietic stem cell transplantation (HSCT), but access is not universal. As benchmarking is now integrated into the FACT-JACIE standards, the EBMT and JACIE established a Clinical Outcomes Group (COG) to develop and introduce a universal system accessible across EBMT members. Established systems from seven European countries (United Kingdom, Italy, Belgium, France, Germany, Spain, Switzerland), USA and Australia were appraised, revealing similarities in process, but wide variations in selection criteria and statistical methods. In tandem, the COG developed the first phase of a bespoke risk-adapted international benchmarking model for one-year survival following allogeneic and autologous HSCT based on current capabilities within the EBMT registry core dataset. Data completeness, which has a critical impact on validity of centre comparisons, is also assessed. Ongoing development will include further scientific validation of the model, incorporation of further variables (when appropriate) alongside implementation of systems for clinically meaningful interpretation and governance aiming to maximise acceptance to centres, clinicians, payers and patients across EBMT.

This article contributes to understanding the role and position of worker cooperatives in society, providing an socio-political explanation to their existence as well as conceptual tools that can be used to imagine and implement economic democracy practices. It uses and complexifies Habermas’ social theory and its separation between system and lifeworld to show that cooperatives may act, intentionally and idealistically, at the interface of these two domains. This positioning enables cooperatives to participate in resisting colonisation of the lifeworld by endowing individuals with resources favouring communicative action and by redefining institutional arrangements within the system. This article identifies factors explaining the varying degrees of resistance to colonisation by cooperatives. It also contributes to theorising the potential effects of organizing work in an economically democratic way. [less ▲]

In this paper, we propose an extension to the policy gradient algorithms by allowing starting states to be sampled from a probability distribution that may differ from the one used to specify the reinforcement learning task. In particular, we suggest that, between policy updates, starting states should be sampled from a probability density function which approximates the state visitation frequency of the current policy. Results generated from various environments clearly demonstrate a performance improvement in terms of mean cumulative rewards and substantial update stability compared to vanilla policy gradient algorithms where the starting state distributions are either as specified by the environment or uniform distributions over the state space. A sensitivity analysis over a subset of the hyper-parameters of our algorithm also suggests that they should be adapted after each policy update to maximise the improvements of the policies.

Polyurethane (PU) foams are indisputably daily essential materials found in many applications, notably for comfort (e.g. matrasses) or energy saving (e.g. thermal insulation). Today, greener routes for their production are intensively searched for avoiding the use of toxic isocyanates. We now describe an easily scalable process for the simple construction of self-blown isocyanate-free PU foams by exploiting the organocatalyzed chemo- and regio-selective additions of amines and thiols to easily accessible cyclic carbonates. These reactions are first validated on model compounds and rationalized by DFT calculations. Various foams are then prepared and characterized in terms of morphology and mechanical properties, and the scope of the process is illustrated by modulating the composition of the reactive formulation. Due to the impressive diversity and accessibility of the main components of the formulations, this new robust and solvent- free process is opening avenues for constructing more sustainable PU foams, and offers the first realistic alternative to the traditional isocyanate route.

La christianisation d'une communauté est un long processus, variable dans les modalités comme dans la durée d’une région à l’autre, dont il est difficile d'établir précisément la chronologie. Ce constat méthodologique a amené certains historiens à proposer des chrono-typologies permettant d'apprécier l'évolution de l'implantation du christianisme. Les recherches sur la christianisation de Huy, vicus du bassin de la Meuse moyenne, ont été pour l’auteur, l’occasion d’éprouver la chrono-typologie tri-phasée de Martine De Reu. Il postule ainsi que cette agglomération fut successivement une « région païenne » des origines au début du Ve siècle, une « région mixte » du début du Ve siècle au début du VIIe siècle et enfin une « région chrétienne » à partir du début VIIe siècle. Cette enquête met en lumière l’intérêt du cas hutois pour l’étude la christianisation du nord de la Gaule, dans la mesure où rares sont, pour cette région, les sites occupés « continuellement » entre l’Antiquité tardive et l’époque mérovingienne pour lesquels on dispose de témoignages littéraires et de traces archéologiques suffisantes pour tirer des conclusions sur le changement du paysage religieux.

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 ▲]

Osteoarthritis (OA) is the most prevalent musculoskeletal disease and a major cause of negative relevant outcomes, associated with an ever-increasing societal burden. Pharmaceutical-grade chondroitin sulfate (CS) was repeatedly reported to reduce pain and improve function in patients with OA. This article aims to review the evidence for the role of highly purified (hp) CS (Condrosulf®, IBSA) in the treatment of OA. We collected and reported evidence concerning (1) efficacy of hpCS 800 mg/day in the treatment of OA affecting the knee, hand and hip; (2) efficacy and safety of hpCS 1200 mg/day also in the oral gel formulation; (3) the safety profile of hpCS; (4) the difference of hpCS and pharmaceutical-grade formulations versus food supplements; (5) pharmacoeconomic added value of hpCS. The data support that hpCS is an effective and safe treatment of OA, with its effect already evident at 30 days; in addition, its beneficial action is prolonged, being maintained for at least 3 months after the drug is discontinued. Full safety reports’ analyses confirm that CS is safe to use and has almost no side effects, in particular, it showed better gastrointestinal tolerance if compared with non-steroidal anti-inflammatory drugs (NSAIDs). Moreover, the therapeutic strategy has proved to be cost-effective: treatment with CS reduced the use of NSAIDs and their side effects. © 2020, The Author(s). [less ▲]

Objectives: To evaluate patients’ preferences for sarcopenia outcomes. Design: Discrete-choice experiment (DCE) Setting and Participants: Community-dwelling individuals older than 65 years suffering from sarcopenia recruited in Belgium, France, Germany, Italy, Spain, and Switzerland, who visited the clinic and were cognitively able to understand and fill out the survey. Methods: In the DCE survey, participants were repetitively asked to choose which one of the 2 patients suffering from sarcopenia deserves treatment the most. The 2 patients presented different levels of risk for 5 preselected sarcopenia outcomes: quality of life, mobility, domestic activities, fatigue, and falls. The DCE included 12 choice sets. Mixed logit panel model was used to estimate patients’ preferences and latent class model was conducted to identify profiles of responses. Results: Atotal of 216 sarcopenic personswere included for the analysis (68%women;mean age 78 years). All 5 preselected sarcopenia outcomes were shown to be significant. Overall, the most important sarcopenia outcome was mobility (30%), followed by the ability to manage domestic activities (22%), the risk of falls (18%), fatigue (17%), and quality of life (14%). The latent class model identified 2 classes of respondents. In the first class (probability of 56%), participants valued mobility the most (42%), followed by the ability to manage domestic activities (23%) and risk of falls (17%). In the second class, fatiguewas the most important outcome (27%) followed by domestic activities (19%) and risk of falls (19%). No statistically significant associations between the latent classes and sociodemographic characteristics were found. Conclusions and Implications: This study suggests that all 5 preselected outcomes were important for sarcopenic older individuals. Overall, the most important outcomes were mobility and the ability to manage domestic activities, although variations in preferenceswere observed between respondents. This could help in incorporating patient preferences when designing appropriate solutions for individuals with sarcopenia. [less ▲]

In Antarctica, amphipods form a highly diverse group, occupy many different ecological niches and hold an important place in food webs. Here, we aimed to test whether differences in Antarctic amphipod feeding habits were reflected in their mandible morphology, and if mouthpart specialization could be used to describe amphipod trophic ecology. To do so, we compared mandible morphology in nine species spanning seven families and five functional groups (grazers, suspension feeders, generalist predators, specialist predators and scavengers). Mandible morphology adequately depicted some aspects of amphipod trophic ecology, such as the trophic level at which animals feed or their degree of dietary specialization. On the other hand, links between mandible morphology and amphipod diet were seldom unambiguous or straightforward. Similar adaptations were found in distinct functional groups. Conversely, mandible morphology could vary within a single functional group, and phylogenetic effects sometimes complicated the interpretation of form-function relationships. Overall, mandible morphology on its own was generally not sufficient to precisely predict amphipod feeding strategies. However, when combined with other methods (e.g. gut contents, trophic markers), it constitutes a valuable source of information for integrative studies of amphipod ecological diversity in the Southern Ocean.

Given any numeration system, we call carry propagation at a number N the number of digits that are changed when going from the representation of N to the one of N+1, and amortized carry propagation the limit of the mean of the carry propagations at the first N integers, when N tends to infinity, if this limit exists.In the case of the usual base p numeration system, it can be shown that the limit indeed exists and is equal to p/(p −1). We recover a similar value for those numeration systems we consider and for which the limit exists.We address the problem of the existence of the amortized carry propagation in non-standard numeration systems of various kinds: abstract numeration systems, rational base numeration systems, greedy numeration systems and beta-numeration. We tackle the problem with three different types of techniques: combinatorial, algebraic, and ergodic. Fo r each kind of numeration systems that we consider, the relevant method allows for establishing sufficient conditions for the existence of the carry propagation and examples show that these conditions are close to being necessary conditions.

Introduction: Several pharmacological treatments aiming at a better symptomatic control of osteoarthritis (OA) are used in daily practice but their efficacy is often disputed. The purpose of this network meta-analysis (NMA) is to assess the efficacy on pain and function of the drugs that are most widely prescribed against knee OA. Methods: Medline, Scopus, and Cochrane database of systematic reviews were searched for randomized controlled trials published up to August 2019 and assessing the efficacy of knee OA treatments using a 6-month time horizon. Pain and function changes from baseline were the primary outcomes. A Bayesian network meta-analysis was run and standardized mean differences (SMDs) with 95% credibility intervals (95% CrIs) were calculated. Results: 9697 references were identified and 80 RCTs were concordant with our inclusion criteria (79 studies involving 15,609 individuals reported pain outcomes and 55 studies involving 13,655 individuals reported function outcomes). A significant decrease in pain was observed for the intra-articular (IA) combination of hyaluronic acid (HA) and triamcinolone (SMD − 0.49, 95% CrI − 0.78; − 0.19), vitamin D (SMD − 0.31, 95% CrI − 0.56; − 0.06), IA HA (SMD − 0.29, 95% CrI − 0.40; − 0.17), prescription-grade crystalline glucosamine sulfate (pCGS) (SMD − 0.29, 95% CrI − 0.58; − 0.004), and prescription-grade chondroitin sulfate (pCS) (SMD − 0.26, 95% CrI − 0.44; − 0.08). Significant improvements in physical function were found with pCGS (SMD − 0.44, 95% CrI − 0.66; − 0.21), vitamin D (SMD − 0.30, 95% CrIs − 0.49; − 0.11) and IA HA (SMD − 0.21, 95% CrIs − 0.31; − 0.11). Conclusion: Six months of treatment with IA HA, pCGS, pCS, vitamin D and the combination of IA HA and triamcinolone improve pain and/or physical function in patients suffering from knee OA. [less ▲]

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 ▲]

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 ▲]

1. Paedomorphosis, a developmental heterochrony involving the retention of larval traits at the adult stage, is considered a major evolutionary process because it can generate phenotypic variation without requiring genetic modifications. Two main processes underlie paedomorphosis: neoteny, a slowdown of somatic development, and progenesis, a precocious maturation associated to body size reduction. Being essentially a truncation of ontogeny, progenesis has often been deemed an evolutionary dead-end with advantages attributed to precocious reproduction or small body size required in specific environmental contexts (e.g. parasitism, interstitial life), but there is a lack of studies on the immediate ecological consequences of progenesis. 2. Because body size is a key factor determining trophic ecology in animals, we hypothesized that progenesis might intrinsically promote ecological opportunity via body size reduction (i.e. ‘the trophic advantage of progenesis’ hypothesis). We tested this hypothesis in facultatively progenetic palmate newts (Lissotriton helveticus) using stable isotope niche modelling and diet reconstruction in conjunction with traditional stomach content analyses and body condition assessment. 3. We show that not only did progenetic individuals occupy a different trophic niche than metamorphic individuals in all populations, but the smaller they were compared to metamorphs due to progenesis, the more different they were in terms of trophic ecology, with no negative effect on their body condition. 4. Altogether, the results suggest that via body size reduction, progenesis may generally act as an intrinsic factor of ecological opportunity, allowing the use of existing but previously unavailable resources, even in habitats where seemingly little opportunity exists. We argue that beyond the classically recognized fitness advantages of progenetic development, this process may also generally bring an immediate trophic advantage via body size reduction, which would have important implications to understand the evolution and adaptiveness of this process in many different taxa, from marine meiofauna to primates.

BACKGROUND: Functional ankle instability affects 20-40% of individuals who have already suffered from a sprain. Such dysfunctions are difficult to diagnose. Therefore, the information provided by self-administered questionnaires is essential. Thus, the Ankle Instability Instrument (AII) was developed and initially validated in English. Our goal is to create a French version of the instrument, named AII-F, by scrupulously respecting the cultural adaptation phases and to make sure the new instrument has good psychometric properties. METHODS: International recommendations have been rigorously followed for the cultural adaptation and the French-translation phase. Six steps are recommended: I) two initial translations from English to French; II) synthesis of the two versions; III) back-translations from French to English; IV) comparisons between the back-translations and the original questionnaire by the expert committee; V) pretest; and VI) approval of the final French version of the AII. In order to validate this French-translation, 91 subjects suffering from ankle instability matched to 91 healthy subjects were asked to complete the AII-F. The Short Form Health Survey (SF-36) was used as a comparative questionnaire as well as the French Cumberland Ankle Instability Tool (CAIT-F). The psychometric properties of the questionnaire were evaluated by determining the test-retest reliability after a 10-14-day interval, the internal consistency, construct validity, and the floor/ceiling effects. RESULTS: The French-translation did not pose a problem and could be validated by the expert committee. The AII-F showed a very good test-retest reliability for the total score, with an Intra Class Coefficient of 0.983. The internal coherence is high with an alpha coefficient of Cronbach of 0.861. The association of the AII-F with the CAIT-F was high, for the summary of the physical component of the SF-36, meaning a great convergent validity. The other subscales of the SF-36 (mental health) were weakly correlated with the AII-F, reflecting good divergent validity. An optimal cut-off score was obtained to dissociate pathological patients from healthy subjects: when the subject responded to "yes" 5 times or more, he is considered, with a very high degree of confidence, to be pathological. CONCLUSION: The AII-F is reliable and valid for evaluating and measuring functional ankle instability. [less ▲]

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.

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 ▲]

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.

Transmission line outage rates are fundamental to power system reliability analysis. Line outages are infrequent, occurring only about once a year, so outage data are limited. We propose a Bayesian hierarchical model that leverages line dependencies to better estimate outage rates of individual transmission lines from limited outage data. The Bayesian estimates have a lower standard deviation than estimating the outage rates simply by dividing the number of outages by the number of years of data, especially when the number of outages is small. The Bayesian model produces more accurate individual line outage rates, as well as estimates of the uncertainty of these rates. Better estimates of line outage rates can improve system risk assessment, outage prediction, and maintenance scheduling. [less ▲]

Cette étude est faite dans la fonction publique en RDC, elle consiste à identifier les barrières individuelles, organisationnelles et sociétaux qui empêchent les femmes à accéder aux postes supérieurs. Celles-ci peuvent créer une démotivation et un manque de confiance de la part des femmes envers les organisations. L’observation faite dans les divisions provinciales de la fonction publique du Haut-Katanga est qu’ aux emplois de collaboration les femmes représentent 21% contre 79% d’hommes, à ceux de coordination et d’encadrement 12% contre 88%, aucune femme directeur de province. L’objectif est d’identifier les causes du plafond de verre dans ces divisions et proposer une piste de solution pour l’amélioration de l’égalité professionnelle hommes-femmes. Nos résultats ont identifié quatre barrières : la différence ethnoculturelle, les promotions subjectives suite aux interférences politiques, le harcèlement sexuel et le manque de politique écrite d’égalité hommes-femmes.

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 ▲]

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 ▲]

The generalisation of linguistic constructions is performed through analogical reasoning. Children with developmental language disorders (DLD) are impaired in analogical reasoning and in generalisation. However, these processes are improved by an input involving variability and similarity. Here we investigated the performance of children with or without DLD in a construction generalisation task. We also compared their performance following training with an input involving progressive alignment (combining similarity and variability) or high variability. Progressive alignment improves construction generalisation in children with or without DLD, which could have implications for our understanding of language development and for interventions conducted with children with DLD.
