BACKGROUND: Nine core domains for tendinopathy have been identified. For Achilles tendinopathy there is large variation in outcome measures used, and how these fit into the core domains has not been investigated. OBJECTIVE: To identify all available outcome measures outcome measures used to assess the clinical phenotype of Achilles tendinopathy in prospective studies and to map the outcomes measures into predefined health-related core domains. DESIGN: Systematic review. DATA SOURCES: Embase, MEDLINE (Ovid), Web of Science, CINAHL, The Cochrane Library, SPORTDiscus and Google Scholar. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Clinical diagnosis of Achilles tendinopathy, sample size ≥ ten participants, age ≥ 16 years, and the study design was a randomized or non-randomized clinical trial, observational cohort, single-arm intervention, or case series. RESULTS: 9376 studies were initially screened and 307 studies were finally included, totaling 13,248 participants. There were 233 (177 core domain) different outcome measures identified across all domains. For each core domain outcome measures were identified, with a range between 8 and 35 unique outcome measures utilized for each domain. The proportion of studies that included outcomes for predefined core domains ranged from 4% for the psychological factors domain to 72% for the disability domain. CONCLUSION: 233 unique outcome measures for Achilles tendinopathy were identified. Most frequently, outcome measures were used within the disability domain. Outcome measures assessing psychological factors were scarcely used. The next step in developing a core outcome set for Achilles tendinopathy is to engage patients, clinicians and researchers to reach consensus on key outcomes measures.

The present study examined the evolution observed in amnesic patients’ use of motor fluency when making recognition memory decisions. In this experiment, 9 patients with amnesia and 18 matched controls were presented with two recognition memory tasks composed of 3 types of items: (a) natural words, (b) nonwords difficult to pronounce, and (c) nonwords easy to pronounce, the latter having been shown to be processed in a surprisingly fluent manner as long as participants can articulate them at a subvocal level (i.e., oral motor fluency). Our results provide evidence that the motor-movement manipulation was successful to induce a fluency effect. More specifically, data revealed that both amnesic patients and control participants showed a pattern of response consistent with the use of fluency as a cue to memory for studied items. However, only control participants relied on fluency to increase their rate of “yes” responses for unstudied items. These results suggest that patients with amnesia set a more conservative response criterion before relying on oral motor fluency, showing a pattern consistent with the idea that fluency is only used as a cue to memory when it exceeds a certain threshold. These findings are discussed in terms of adaptative metacognition strategies implemented by amnesic patients to reduce fluency-based memory errors as well as in terms of the variations that seem to occur in these strategies depending on the type of fluency that is experienced.

This study aimed to examine ageist attitudes in psychology students who may become the healthcare professionals. We also compared cultural differences between attitudes in Belgium and Quebec. We hypothesized that psychology students would have more positive attitudes toward older people in Quebec than in Belgium. Quebec has indeed more invested in age-friendly initiatives that may promote socio-economic factors associated with better attitudes toward older people. A total of 236 psychology students participated in this study (81 Belgian students and 155 Quebec students). The students completed different self-reported questionnaires to assess their attitudes toward older people. As predicted, the results showed that students in Quebec were overall less negative toward older adults. Since negative attitudes may influence students’ choice to work with older people and may also have damaging consequences in the assessment and/or healing context, we discuss different directions to improve these attitudes.

This paper attempted to identify the determinant factors of innovative technologies preferences by small-scale farmers in the Volcanic Highlands in Rwanda. Data used were collected from a random sample of 401 small-scale crop producers using a structured questionnaire in the study area. A logit regression model was specified, whereby a binary maximum likelihood estimation method was used to identify the factors affecting of the adoption of chemical fertilizers, the determinants of the combined use of chemical and organic fertilizers, the determinants of the adoption of improved seeds, as well as the determinant factors of appropriate use of pesticides. The results showed that farmer’s education level, farming experience, membership to farm cooperative, the number of extension visits, and crop farming are the factors that affect positively the probability of adopting one or other of the four innovative farming techniques. From these results, we suggest the enhancement of extension services and other needed support to small-scale farmers (grants and subsidies, access to finance for example), the spread of professional trainings to farmers, and the increased farmers’ access to high-yielding seed varieties if farming professionalization and innovative farming techniques are still among the development goals.

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.

Objective: To assess the skeletal, dento-alveolar and dental effects of the class II Carriere motion® on young subjects. Materials and Methods: 32 class II subjects (mean age 9.4 ± 1.6 years) were randomly allocated to either the Carriere motion® appliance group (n=15), or to a control group (n=17). Digital dental cast measurements and cephalometric analysis were performed before treatment (T0), at removal of the device for the appliance group, and after a period of 9 months for the control group (T1). The duration of treatment was recorded and the patient’s satisfaction with the appliance was assessed through a questionnaire. Results: The effects of the Carriere Motion leading to Class I were essentially dento-alveolar. Significant decreases of ANB and SNA angles were evidenced, as well as an increase by 1.3 degree of FMA angle compared to control subjects. Distalization and distal rotation of upper molars were observed. The mandibular teeth mesialized and the lower incisors proclined. A clockwise rotation of the occlusal plane occurred. The treatment lasted 7.6 ± 1.6 months with a mean of 6.1 ± 1.1 appointments. The patient experience with the Carriere motion® was quite positive. Conclusion: The Carriere motion® proved its efficiency in correcting class II malocclusion, essentially by dento-alveolar effects. This easy-to-use appliance is indicated in early orthodontic treatment, when the correction is urgently required (prevention of incisor trauma in case of large overjet, periodontal risk for upper incisor in case of deep bite and sleep apnea).

AIM: The European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) algorithm for the management of knee osteoarthritis (OA) is available worldwide from 2014, but in 2019 an update was published. Based on this algorithm, a Working Group (WG), including ESCEO members and Chinese experts, wished to see how the new ESCEO algorithm was perceived by Chinese experts in knee OA and how it was integrated into their clinical practice. METHODS: A WG was held between members of the international ESCEO task force and a group of Chinese experts. RESULTS: Non-pharmacological approach should be combined with pharmacological interventions. In step 1, symptomatic slow-acting drugs for osteoarthritis (SYSADOA) are the most important background drugs. Evidence, supported by high-quality research, is available only for crystalline glucosamine sulfate (pCGS) and chondroitin sulfate. Topical NSAIDs could be used as an additional option. In step 2, oral NSAIDs could be useful, but cardiovascular/renal/gastrointestinal profiles of the patients should be considered. Intra-articular hyaluronic acid and corticosteroids are alternative to oral NSAIDs, but the evidence is still limited. If steps 1 and 2 are not sufficient, weak opioids could be used. Overall, the conclusions of the ESCEO algorithm are accepted in China for products available in this country. The WG suggests the importance of economic studies, specifically made in China. CONCLUSION: This work provides evidence-based advice to establish a treatment algorithm in knee OA, for practical implementation in clinical practice in China. [less ▲]

The Belgian Hematology Society (BHS) updated the 2013 guidelines for diagnosis and treatment of primary immune thrombocytopenia (ITP) [1]. As knowledge about ITP pathophysiology is increasing, the mode of action of old therapies is better understood and novel drugs are introduced to target more specific pathways. Corticosteroids with or without intravenous immunoglobulins (IgIV) remain the first-line treatment. According to the updated international guidelines a short course of corticosteroids rather than a prolonged treatment has to be recommended. The same guidelines stress that consequent therapies as thrombopoietic agents (TPO-RAs) and rituximab should be available independent of duration of ITP. Although the majority of recommendations is based on very low-quality evidence, it is strongly advised to individualize the ITP management taking patient values. and preferences in account. The main treatment goal in all ITP patients must be to maintain a safe platelet count to prevent or stop bleeding with a minimum of toxicity and not to normalize the platelet count. [less ▲]

Abstract: Background: The use of symptomatic slow-acting drugs for osteoarthritis (OA) (e.g., glucosamine, chondroitin) is largely debated in the scientific literature. Indeed, multiple formulations of these agents are available, both as pharmaceutical-grade products and as nutritional supplements, but while all preparations may claim to deliver a therapeutic effect, not all are supported by clinical evidence. Moreover, few data are available regarding the cost-effectiveness of all these formulations. Usually, access to individual patient data is required to perform economic evaluations of treatments, but it can be challenging to obtain. We previously developed a model to simulate individual health utility scores from aggregated data obtained from published OA trials. Objective: In the present study, using our new simulation model, we investigated the costeffectiveness of different glucosamines used in Germany. Methods: We used our validated model to simulate the utility scores of 10 published trials that used different glucosamine preparations. Using the simulated utility scores, the quality-adjusted life years (QALYs) were calculated using the area-under-the-curve method. We used the 2018 public costs of glucosamine products available in Germany to calculate the Incremental Cost/Effectiveness Ratio (ICER). We performed analyses for pharmaceutical-grade Crystalline Glucosamine Sulfate (pCGS) and other formulations of glucosamine (OFG). A cost-effectiveness cut-off of 30,000 €/QALY was considered. Results: Of 10 studies in which utility was simulated, four used pCGS, and six used OFG. The ICER analyses showed that pCGS was cost-effective compared to a placebo, with an ICER of 4489 €/QALY at month 3, 4112 €/QALY at month 6, and 9983 €/QALY at year 3. The use of OFG was not cost-effective at any of the time points considered. Conclusion: Using our previously published model to simulate the individual health utility scores of patients, we showed that, in the German context, the use of pCGS could be considered costeffective, while the use of OFG could not. These results highlight the importance of the formulation of glucosamine. [less ▲]

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. Unilateral vocal fold paralysis (UVFP) often leads to significant morbidity that may include dysphonia, swallowing problems and aspiration. The best timing for medialization procedures is still controversial. Published data suggest that early intracordal injection positively affects long-term outcomes. Objectives. To critically review current literature in order to determine if early treatment of acute UVFP influences clinical outcomes of the patients. Type of Review. Nonsystematic literature review. Methods. A literature review was performed, using the Pubmed database. All relevant articles published in English addressing the effect of early treatment in acute unilateral focal fold paralysis were analyzed. Twenty-six articles were included due to their scientific interest. Results. Published literature suggests that early intracordal injection in patients with UVFP reduces pulmonary infections, hospital length of stay and improves voice parameters. Also, patients who receive early intracordal injection seem to be less likely to undergo subsequent medialization thyroplasty. Conclusions. Early intracordal injection should be offered to patients with newly diagnosed UVFP since it promotes a satisfactory position of the vocal fold and seems to improve clinical outcomes. More investigation, with long-term follow up data and treatment randomization, is necessary to develop clinical consensus for these patients. [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.

Zu Beginn des 10. Jahrhunderts wurden acht Briefe auf die Rückseite des 1882 entdeckten ‚Rotulus von Ravenna‘ niedergeschrieben: Sieben haben Erzbischof Johannes von Ravenna (905–914), den zukünftigen Papst Johannes X. (914–928), einer Papst Sergius III. (904–911) zum Autor. In der Forschung wurden diese Schreiben bisher ausschließlich als einzelne Dokumente wahrgenommen. Der folgende Aufsatz verfolgt das Ziel, die Briefe erstmals in ihrer Gesamtheit zu betrachten, als Briefsammlung deren einzelne Teile bewusst ausgewählt und angeordnet wurden. Dazu wird zunächst das schwierige Verhältnis zwischen der Datierung der Briefe und ihrer Platzierung auf der Rolle behandelt: Die Argumente, die bisher für eine stringent chronologische Anordnung der Briefe angeführt wurden, sind nämlich nicht stichhaltig. Gleichzeitig können jedoch keine Faktoren ausgemacht werden, die eine präzise Datierung ermöglichen würden. Anschließend wird die Ausrichtung der Sammlung näher betrachtet. In sämtlichen Briefen tritt Johannes als unermüdlicher Verteidiger der Kirche von Ravenna in Erscheinung. Darüber hinaus ist die Abfolge der Schreiben geprägt von der Bedeutungssteigerung der verschiedenen Personen, mit denen Johannes in Kontakt tritt.

Objective. To analyze the range of values of the contact pressure between the membranous vocal folds with Reinke’s edema and to compare it to those observed in the absence of such a lesion. Methods. Two human larynges were separately tested on the experimental bench, one of them with a bilateral loose swelling of the vocal folds. Once in a glottal prephonatory configuration, airflow was increased until achievement of self-sustained oscillations while recording aerodynamic, acoustic, electroglottographic data, and contact pressure between the folds. Results. We observed well-documented variations in acoustical parameters, as the decrease of the fundamental frequency and the increase of the phonation threshold pressure. The results of the study also point to a significant increase in the amplitude of the contact pressure in presence of the Reinke’s edema, and a lower degree of harmonicity of the produced sounds. Conclusion. This is the first report of ex vivo study of a larynx with Reinke’s edema. It highlights the increase in the contact pressure during phonation, which possibly contributes to sustain the lesion once it appeared. [less ▲]

As the inverter-based generation replaces the conventional synchronous generators, it may also need to fill in the missing ancillary service support. One of these ancillary services is dynamic reactive power provision and voltage control. This paper analyzes optimal strategy of reactive and active fault-current support of the inverter-based generation leading to fast voltage recovery of the system. For the purpose of the analysis, new ramping active current controller able to emulate different behavior of active current injection is proposed. By optimizing its parameters for different case studies of the system, the conclusions about optimal behavior of the inverter based generation with respect to system parameters and operating conditions are drawn. It is observed that the optimal combination of active and reactive fault-current is the most sensitive to the dynamic load component penetration levels in the system. With the increasing penetration levels, the significance of active fault current injection increases. The results show that with higher penetration levels of dynamic load component in the heavy load areas, the ramping down of the inverter-based generation active fault-current results in slower voltage recovery of the system. Following this conclusion, a recommendation on update of current European grid codes is proposed. [less ▲]

In France, the Rassemblement National and, in Austria, the Freiheitliche Partei Österreichs aim to “recover”, “restore” or “protect” democracy. In this article, I will study their use of the term “democracy” by focusing on its temporal dimension. Their discourse tells a story, that of a glorious past which should be revived. Adopting a critical discourse analysis approach, I will answer the following questions: what kind of temporality is conveyed by the term “democracy”?, and, if “democracy” is perceived as a “lost world”, then what vision do those politicians who support the ideology of the two political parties have of tomorrow’s “democracy”? I would maintain that whilst these parties present themselves as agents of a democratic renewal, their vision of “democracy” remains traditional, i.e. essentially representative and vertical. The term “direct democracy” is limited to particular subjects (the EU, immigration, international agreements) and these parties are critical of electoral reforms or new forms of participation.

An increasing amount of research has examined the management of competing logics, and possible tensions arising between them, within “hybrid organizations”. However, the ways in which the relationships of hybrids with other organizations shape the conciliation of these logics and tensions has received limited attention so far. In this theoretical paper, we examine how hybrid organizations deal with interorganizational collaboration, in particular whether and how their hybridity can be maintained when they partner with “dominant-logic organizations”. Drawing on empirical literature on social enterprise-corporate collaborations, we develop a framework and several propositions on how competing logics and their balancing within hybrid organizations may be affected by interactions with organizations underpinned by one dominant logic. We suggest that influences will mostly depend on the type of collaboration pursued. A collaboration based on a lower level of engagement and interaction between the two partners is likely to give precedence to one logic over the other, reducing inter-logic tensions but possibly compromising organizational hybridity. By contrast, a collaboration featuring numerous interactions and mission compatibility may facilitate sustained hybridity if tensions are acknowledged and managed. Our propositions contribute to the literatures on hybrid organizations, interorganizational collaboration, and social enterprise. [less ▲]

Following the municipal elections in the Walloon Region (Belgium) on 14 October 2018, 189 political groups won an absolute majority. Twenty-too of these decided not to exercise power alone, but to favour the formation of an oversized coalition by integrating a minority partner. The aim of this article is to identify the motivations behind the formation of a local coalition when one of the partners has an absolute majority. Semi-structured interviews with mayors and leaders of political groups in these municipalities make it possible to identify the motivations for first the choice to open and second the choice of a minority partner. By distinguishing between necessary and supporting motivations, this article shows that the search for greater representation is a necessary motivation for the choice to open, whereas personal affinities and memories of the past are necessary motivations for choosing minority partners. By prioritising motivations, this article shows that some motivations support the necessary motivations without conditioning the negotiation of an oversized coalition. [less ▲]

We study the class of symmetric $n$-ary bands. These are $n$-ary semigroups $(X,F)$ such that $F$ is invariant under the action of permutations and idempotent, i.e., satisfies $F(x,\ldots,x)=x$ for all $x\in X$. We first provide a structure theorem for these symmetric $n$-ary bands that extends the classical (strong) semilattice decomposition of certain classes of bands. We introduce the concept of strong $n$-ary semilattice of $n$-ary semigroups and we show that the symmetric $n$-ary bands are exactly the strong $n$-ary semilattices of $n$-ary extensions of Abelian groups whose exponents divide $n-1$. Finally, we use the structure theorem to obtain necessary and sufficient conditions for a symmetric $n$-ary band to be reducible to a semigroup. [less ▲]

Malaria remains one of the deadliest infectious disease in 2021. Indeed, this infection, mostly caused by a protozoon called Plasmodium falciparum, is responsible annually for more than 200 million cases and around 400 000 related deaths, mainly in Africa. Despite the availability of efficient drugs, we observe an increase of patients since 2015, which could find its origin in development of resistances from the parasite but also from its vectors, Anopheles mosquitoes. Consequently, it is necessary to search for new alternative treatments. Polyphenols, and more precisely small phenolic acids, could represent a good starting point for new antimalarials. Indeed, these molecules, such as caffeic acid (1), exhibit several pharmacological activities and an interesting pharmacokinetic profile. Therefore, we have developed several small derivatives of this scaffold to define the potential pharmacophore responsible for the antiplasmodial properties. We have obtained a good to low activity on Plasmodium (IC50 = 16-241 µM) with selectivity against human cells, especially for small esters (2-6, SI > 3). These structures have highlighted the need of catechol and carboxyl moieties in the anti-Plasmodium effect. Unfortunately, none of them seemed sufficiently effective to become a new antimalarial, but they could be new leads for future development. [less ▲]

Entomophagy is well established in the food habits of Africa; however, country-wide knowledge remains limited for several countries, including Gabon. Here, two surveys on entomophagy were conducted in Gabon through face-to-face interviews. The first survey collected information on insect eating habits from 169 potential consumers. Edible insects formed part of the diet of most Gabonese people, with more than 60% of consumers within participants, and were particularly common among the Teke ethnic group (93%). Familiarity with edible insects was influenced by culture and family, but not by gender or study level. The second survey focused on edible insect species and their host plants, by interviewing a sample of 113 both villagers and retailers. Seventy-five species of insects from six insect orders (Coleoptera, Hemiptera, Isoptera, Lepidoptera, Odonata and Orthoptera) were consumed in Gabon, and were collected from 48 species of host plant. Many insects were formerly reported in the literature related to entomophagy; however, 13 species were newly reported as edible in this study: Bidessus batekensis, Bunaeopsis licharbas, Copelatus ateles, Copelatus confinis, Copelatus fizpaci, Copelatus tondangoyei, Gonobombyx angulata, Gonometa titan, Hydrocyrius columbiae, Oxychirus semisericeus, Philobota sp., Psara sp. and Ptyelus flavescens. Consequently, these surveys highlighted that entomophagy is common in Gabon. However, strategies to promote edible insects are needed to have a significant impact on food issues in Gabon (e.g. food insecurity and dependence on foreign food supplies). Additional researches on entomophagy in Gabon are required to further develop these strategies. [less ▲]

We propose a dynamic measure of extremal connectedness tailored to the short reporting period and unbalanced nature of hedge funds data. Using multivariate extreme value regression techniques, we estimate this measure conditional on factors reflecting the economic uncertainty and the state of the financial markets, and derive risk indicators reflecting the likelihood of extreme spillovers. Empirically, we study the dynamics of tail dependencies between hedge funds grouped per investment strategies, as well as with the banking sector. We show that during crisis periods, some pairs of strategies display an increase in their extremal connectedness, revealing a higher likelihood of simultaneous extreme losses. We also find a sizable tail dependence between hedge funds and banks, indicating that banks are more likely to suffer extreme losses when the hedge fund sector does. Our results highlight that a proactive regulatory framework should account for the dynamic nature of the tail dependence and its link with financial stress. [less ▲]

In this paper, a reliable methodology is proposed in order to implement and validate a Model Predictive Control (MPC) scheme on an actual Voltage Source Converter (VSC) integrated in a scale-down multi-terminal DC grid. The objective of the investigated MPC controller is to enable AC frequency support among two asynchronous AC areas through a High Voltage Direct Current (HVDC) grid, while considering physical constraints, such as maximum and minimum DC voltage. A systematic and accurate implementation strategy is proposed, based mainly on the Hardware In the Loop (HIL) and Power Hardware In the Loop (PHIL), leading to the real-life testing on VSC, controlled by a classical microcontroller. The technical problems during the implementation process, as well as the proposed solutions, are described in detail through this paper. This procedure is deemed valuable to bridge the gap between offline simulation and the actual implementation of such advanced control scheme on experimental test rig. [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.

An interlaboratory comparison study was conducted by the Vitamin D Standardization Program (VDSP) to assess the performance of liquid chromatography - tandem mass spectrometry (LC-MS/MS) assays used for the determination of serum total 25-hydroxyvitamin D (25(OH)D), which is the sum of 25-hydroxyvitamin D(2) (25(OH)D(2)) and 25-hydroxyvitamin D(3) (25(OH)D(3)). A set of 50 single-donor samples was assigned target values for concentrations of 25(OH)D(2), 25(OH)D(3), 3-epi-25-hydroxyvitamin D(3) (3-epi-25(OH)D(3)), and 24R,25-dihydroxyvitamin D(3) (24R,25(OH)(2)D(3)) using isotope dilution liquid chromatography - tandem mass spectrometry (ID LC-MS/MS). VDSP Intercomparison Study 2 Part 1 includes results from 14 laboratories using 14 custom LC-MS/MS assays. Assay performance was evaluated using mean % bias compared to the assigned target values and using linear regression analysis of the test assay mean results and the target values. Only 53% of the LC-MS/MS assays met the VDSP criterion of mean % bias ≤ |±5%|. For the LC-MS/MS assays not meeting the ≤ |±5%| criterion, four assays had mean % bias of between 12 and 21%. Based on multivariable regression analysis using the concentrations of the four individual vitamin D metabolites in the 50 single-donor samples, the performance of several LC-MS/MS assays was found to be influenced by the presence of 3-epi-25(OH)D(3). The results of this interlaboratory study represent the most comprehensive comparison of LC-MS/MS assay performance for serum total 25(OH)D and document the significant impact of the lack of separation of 3-epi-25(OH)D(3) and 25(OH)D(3) on assay performance, particularly with regard to mean % bias.

Significance and Impact of the Study: Shiga toxin-producing Escherichia coli (STEC) are important foodborne pathogens responsible for haemorrhagic colitis and haemolytic-uremic syndrome.

Since these serogroups are most frequently implicated in human illness, more information on their presence in the bovine reservoir is required to develop efficient strategies aimed at reducing bovine carriage and the risk of human transmission.

Introduction > There is a growing number of articles describing the roles and impacts of the activity of pharmacists and their collaborators in the community and in health care settings. However, there is no profile of this literature related to pharmacy practice in Belgium. Method > This is a literature review. The main objective was to gather evidence in order to describe and highlight the different characteristics of the role of pharmacists and the impacts of their activities in Belgium. The literature search was carried out in three databases, PubMed, Embase and CINAHL between 01/01/2006 and 30/09/2019. Results > Of the 232 articles identified, 65 were included for analysis. The studies included only descriptive data (73.9%, 48/65) or descriptive data associated with measures of pharmacist impact (26.1%, 17/65). The study highlighted the presence of pharmacists exercising one or the other of the 21 pharmaceutical activities with, in descending order, medication reviews, advice to patients (i.e. ad hoc process that targets a drug), therapeutic education of patients (e.g. continuous, interdisciplinary process, which aims not only to inform but also to train and evaluate the patient) and drug reconciliation activities. Studies were conducted only in pharmacies (53.8%, 35/65), hospitals (29.2%, 19/65), both (7.7%, 5/65) and other practice settings (9.2%, 6/65). Seventeen of the 65 included studies included a measure of the impact of the pharmacist's presence. Of the 35 impact measures associated with pharmaceutical interventions, 23 included positive effects, 12 neutral effects and none of the negative effects. Conclusion > This is the first review of the literature on the roles and impacts of the pharmacist in Belgium. Sixty-five articles were selected, 17 of which included measures of the impact of pharmaceutical activity. Of the 35 impact measures associated with pharmaceutical interventions, 23 included positive effects, 12 neutral effects and none of the negative effects.

Mountainous South Kivu is an agro-pastoral zone in Democratic Republic of Congo where smallscale agriculture is predominant. Due to its location and potential, this region would contribute to the food security of the population of South Kivu and neighbouring territories. This research aimed to establish a characterisation of small-scale farming in this area in order to highlight the factors that differentiate farms. To achieve this objective, we adopted a holistic approach coupled with descriptive statistics, analysis of variance and student's t-test for data analysis. Data were collected from a purposive sample of 211 farmers in 2018 and 2019 respectively. The results revealed that the differentiation of farms is based on the number of plots per farm, the choice of production systems, the cropping system, the land tenure, the gross margin, the gross value added and the net farm income achieved at farm level. Therefore, solutions such as access to finance allowing farmers to diversify their production system, the restoration of security in rural areas, the rehabilitation of the existing and creation of new feeder roads, and the setting and promotion of very strong and dynamic farmers' structures would allow a significant development of agricultural activities in the study area.

The Vitamin D External Quality Assessment Scheme (DEQAS) distributes human serum samples four times per year to over 1000 participants worldwide for the determination of total serum 25-hydroxyvitamin D [25(OH)D)]. These samples are stored at -40 °C prior to distribution and the participants are instructed to store the samples frozen at -20 °C or lower after receipt; however, the samples are shipped to participants at ambient conditions (i.e., no temperature control). To address the question of whether shipment at ambient conditions is sufficient for reliable performance of various 25(OH)D assays, the equivalence of DEQAS human serum samples shipped under frozen and ambient conditions was assessed. As part of a Vitamin D Standardization Program (VDSP) commutability study, two sets of the same nine DEQAS samples were shipped to participants at ambient temperature and frozen on dry ice. Twenty-eight laboratories participated in this study and provided 34 sets of results for the measurement of 25(OH)D using 20 ligand binding assays and 14 liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods. Equivalence of the assay response for the frozen versus ambient DEQAS samples for each assay was evaluated using multi-level modeling, paired t-tests including a false discovery rate (FDR) approach, and ordinary least squares linear regression analysis of frozen versus ambient results. Using the paired t-test and confirmed by FDR testing, differences in the results for the ambient and frozen samples were found to be statistically significant at p < 0.05 for four assays (DiaSorin, DIAsource, Siemens, and SNIBE prototype). For all 14 LC-MS/MS assays, the differences in the results for the ambient- and frozen-shipped samples were not found to be significant at p < 0.05 indicating that these analytes were stable during shipment at ambient conditions. Even though assay results have been shown to vary considerably among different 25(OH)D assays in other studies, the results of this study also indicate that sample handling/transport conditions may influence 25(OH)D assay response for several assays.

METHODS: We established the limits of detection and quantification (LOD-LOQ), linearity, imprecision and the reference ranges in 119 males, 50 women (<45 years) and 120 women (>60 years) for TRACP-5b with the Nittobo assay. We compared both assays in 30 hemodialyzed (HD), and 40 stage 3-5 patients suffering from chronic kidney disease (CKD), 40 patients suffering from rheumatoid arthritis and osteoporosis and 80 post-menopausal women. We measured TRACP-5b, β-crosslaps (β-CTX), bone alkaline phosphatase (B-ALP) and PTH in 20 hemodialyzed (HD) and 40 CKD patients. RESULTS: LOD and LOQ were 0.02 and 0.35 U/L. CV ranged from 8.3 to 4.3% (2/5 samples presenting CV > desirable CV). Method was linear up to of 11.3 U/L. Upper and lower limits of normality were 0.8-7.6 U/L in men, 0.9-4.7 U/L in women <45 and 0.9-7.1 U/L in women >60. The regression equation between the 2 methods was Nittobo = 1.13 (95% CI: 1.09-1.16) × iSYS - 0.4 (95% CI: -0.5; -0.3). TRACP-5b and b-ALP were in their respective reference ranges for most of CKD and HD patients. That was not the case for β-CTX, which increased with decreasing eGFR. CONCLUSIONS: Nittobo TRACP-5b presents interesting analytical features and a good concordance with IDS iSYS. These methods could thus potentially be harmonized. [less ▲]

An intralaboratory study assessing assay variability and bias for determination of serum total 25-hydroxyvitamin D [25(OH)D] was conducted by the Vitamin D Standardization Program (VDSP). Thirteen assays for serum total 25(OH)D were evaluated in a single laboratory including 11 unique immunoassays and one liquid chromatography - tandem mass spectrometry (LC-MS/MS) assay. Fifty single-donor serum samples, including eight samples with high concentrations of 25(OH)D(2) (> 30 nmol/L), were assigned target values for 25(OH)D(2) and 25(OH)D(3) using reference measurement procedures (RMP). Using four replicate measurements for each sample, the mean total percent coefficient of variation (%CV) and mean % bias from the target values were determined for each assay using the 50 single-donor samples and a 42-sample subset, which excluded 8 high 25(OH)D(2) concentration samples, and compared with VDSP performance criteria of ≤ 10% CV and ≤ ±5% mean bias. All 12 assays achieved the performance criterion for %CV, and 9 of the 12 assays were within ≤ ±5 % mean bias. The Fujirebio Inc. assay exhibited the lowest %CV and highest percentage of individual measurements within ≤ ±5% mean bias. Ten immunoassays exhibited changes in response due to the high 25(OH)D(2) samples with Abbott, Biomérieux, DiaSorin, DIAsource, and IDS-iSYS assays having the largest deviations. The Fujirebio Inc. and Beckman Coulter assays were only minimally affected by the presence of the high 25(OH)D(2) samples. Samples with high concentrations of 25(OH)D(2) provided a critical performance test for immunoassays indicating that some assays may not have equal response or recovery for 25(OH)D(2) and 25(OH)D(3).

The recent availability of population-based studies with neuroimaging and behavioral measurements opens promising perspectives to investigate the relationships between interindividual variability in brain regions' connectivity and behavioral phenotypes. However, the multivariate nature of connectivity-based prediction model severely limits the insight into brain-behavior patterns for neuroscience. To address this issue, we propose a connectivity-based psychometric prediction framework based on individual regions' connectivity profiles. We first illustrate two main applications: 1) single brain region's predictive power for a range of psychometric variables and 2) single psychometric variable's predictive power variation across brain region. We compare the patterns of brain-behavior provided by these approaches to the brain-behavior relationships from activation approaches. Then, capitalizing on the increased transparency of our approach, we demonstrate how the influence of various data processing and analyses can directly influence the patterns of brain-behavior relationships, as well as the unique insight into brain-behavior relationships offered by this approach.

Bone turnover markers (BTMs) are released during the bone remodelling cycle and are measurable in blood or urine, reflecting bone remodelling rate. They have been useful in elucidating the pharmacodynamics and effectiveness of osteoporosis medication in clinical trials and are increasingly used in routine clinical management of osteoporosis, especially for monitoring therapy, in addition to their use in other metabolic bone disease such as Paget's disease of bone and osteomalacia. Serum β isomerised C-terminal telopeptide of type I collagen and pro-collagen I N-terminal propeptide have been designated as reference BTMs for use in osteoporosis. In addition, bone-specific isoenzyme of alkaline phosphatase (B-ALP) secreted by osteoblasts and tartrate-resistant acid phosphatase 5b (TRACP-5b) secreted by osteoclasts are also found to be specific markers of bone formation and resorption, respectively. The concentrations of the latter enzymes in blood measured by immunoassay provide reliable measures of bone turnover even in the presence of renal failure. B-ALP is recommended for use in the assessment of renal bone disease of chronic kidney disease, and TRACP-5b shows promise as a marker of bone resorption in that condition. BTMs in blood do not suffer from biological variation to the same extent as the older BTMs that were measured in urine. Appropriate patient preparation and sample handling are important in obtaining accurate measures of BTMs for clinical use. Reference change values and treatment targets have been determined for the reference BTMs for their use in monitoring osteoporosis treatment. Further ongoing studies will enhance their clinical applications. [less ▲]

Graft-versus-host disease (GVHD) is a major cause of toxicity after allogeneic hematopoietic cell transplantation (allo-HCT). While rapamycin (RAPA) is commonly used in GVHD prophylaxis in combination with a calcineurin inhibitor (CNI), the understanding of its mechanism of action on human T cells is still incomplete. Here, we performed an extensive analysis of RAPA effects on human T cells in a humanized mouse model of GVHD, in ex-vivo T-cell cultures and in patients given RAPA plus tacrolimus as GVHD prophylaxis after non-myeloablative allo-HCT. We demonstrate that RAPA mitigates GVHD by decreasing T-cell engraftment and differentiation, inhibiting CD8+ T-cell activation and increasing the long-term IL-2 secretion, thereby supporting regulatory T-cell (Treg) proliferation. In contrast, graft-versus-leukemia effects were not abrogated, as RAPA-treated T cells had increased resistance to apoptosis and retained their effector function and proliferative capacity upon re-stimulation. Importantly, we found that RAPA impact on Treg and CD8+ T cells was closely dependent upon IL-2 signaling and that therapeutic options interfering with IL-2, such as calcineurin inhibitors, antagonize the IL-2-dependent promotion of Treg mediated by RAPA. Our results suggest that RAPA immunological efficacy could be improved in combination with drugs having possible synergistic effects such as the hypomethylating agent 5-azacytidine. [less ▲]

OBJECTIVES: Most data on glomerular filtration rate (GFR) originate from subjects <65 years old, complicating decision-making in elderly living kidney donors. In this retrospective multi-center study, we calculated percentiles of measured GFR (mGFR) in donors <65 years old and extrapolated these to donors ≥65 years old. METHODS: mGFR percentiles were calculated from a development cohort of French/Belgian living kidney donors <65 years (n=1,983), using quantiles modeled as cubic splines (two linear parts joining at 40 years). Percentiles were extrapolated and validated in an internal cohort of donors ≥65 years (n=147, France) and external cohort of donors and healthy subjects ≥65 years (n=329, Germany, Sweden, Norway, France, The Netherlands) by calculating percentages within the extrapolated 5th-95th percentile (P5-P95). RESULTS: Individuals in the development cohort had a higher mGFR (99.9 ± 16.4 vs. 86.4 ± 14 and 82.7 ± 15.5 mL/min/1.73 m(2)) compared to the individuals in the validation cohorts. In the internal validation cohort, none (0%) had mGFR below the extrapolated P5, 12 (8.2%) above P95 and 135 (91.8%) between P5-P95. In the external validation cohort, five subjects had mGFR below the extrapolated P5 (1.5%), 25 above P95 (7.6%) and 299 (90.9%) between P5-P95. CONCLUSIONS: We demonstrate that extrapolation of mGFR from younger donors is possible and might aid with decision-making in elderly donors. [less ▲]

We explore the case for a wealth tax as part of the tax mix. Annual wealth taxes are roughly equivalent to capital income taxes on the assets to which they apply. Wealth taxes differ in purpose from inheritance taxes which are useful adjuncts to income taxes. We recount the arguments for taxing capital income, and for taxing inheritances regardless of whether capital income is taxed. We argue that if the desire to tax asset income and wealth transfers is appropriately addressed by capital income and inheritance taxation, the additional need for an annual wealth tax is minimal.

This paper presents a lab-in-the-field experiment with craftsmen working on renovation projects to assess the effect of training programs and incentive scheme on coordination and cooperation. Workers frequently fail to cooperate and coordinate their tasks when not supervised by a project coordinator. This is particularly important in the construction sector where it leads to a lack of final performance in buildings. We introduce two different incentives: a first contract paying craftsmen only according to their individual performance, and a second contract paying a group of three craftsmen with a weak-link payment according to the group’s worst performance. In addition, we test these incentives on two different subject groups: one is composed of craftsmen trained to coordinate their tasks, and the others are not. The results suggest that trained subjects coordinate at significantly higher effort levels than non-trained subjects when facing an individual-based incentive. However, when facing a group-based incentive, non-trained subjects seem to "catch up" trained subjects in terms of coordination level, while these latter subjects do not significantly increase their performance level.

As a result of growing financial pressures and changing space demands, universities are increasingly looking to modernize and rationalize their workspaces through projects of New Ways of Working (NWoW). So far, extant research has mostly investigated the managerial construct of NWoW and its outcomes on organizational members, leaving the design process leading NWoW to be implemented in local contexts understudied. By contrast, the present study sets out to redefine NWoW as open-ended projects of organizational change that are unavoidably ambiguous and conflictual, hence seeking to overcome the tendency to conceal tensions arising at early stages of the change process under the abstract black-box of “resistance to change”. It is shown that ambiguity, simultaneously understood as an organizational problem causing tensions and as a rhetorical resource enabling collective action, plays a major role in the design process of such equivocal projects. The paper further advances our understanding of ambiguity as a multifaceted concept to bridge between individual rationalities and collective decision-making in the course of complex design processes.

Silicon (Si) accumulation in plant tissues helps alleviate abiotic and biotic stresses, including infestation by insect pests. Here, we tested the hypothesis that Si concentration in maize leaves negatively impacts Spodoptera exigua Hübner (Lepidoptera: Noctuidae) with respect to: (i) feeding preferences; (ii) leaf digestion; and (iii) life history traits. We produced three groups of maize plants cultivated in a hydroponic system that had contrasting Si concentrations in their tissues (i.e., 0.21 ± 0.03, 4.45 ± 0.50 and 8.46 ± 0.61 g Si Kg-1 DW). In choice assays, fifth instars preferentially consumed leaves containing lower Si concentrations. In no choice-assays, we found that the approximate digestibility (AD) of larvae feeding on Si-enriched leaves was not affected. However, these larvae exhibited a 32% reduction in relative growth rates. Higher Si concentration in maize leaves extended larval development by three days; from 18.07 ± 0.29 when feeding on Si- diet to 21.39 ± 0.21 days on the Si++ enriched diet. Silicon also reduced larval survival by 18% and pupal weight by 20%. Our results confirm that Si supplementation in soil enhances the ability of plants to resist infestation with chewing insects, and should be considered as a viable option in the existing range of sustainable management practices.

This paper aims to assess the competition between the priority (major) crops and the non priority (minor) crops. Competition between crops is defined as the significant major differences between two crops in terms of production costs and their performance. Data were collected using a questionnaire administered to a random sample of 226 small scale crop producers including 94 onion producers and 132 potato producers. The T-test was conducted to state whether there is significant difference of mean land sizes, mean crop yields, mean selling prices, and mean net farm incomes between the two groups of crop producers. Results showed non significant difference between the mean land size allocated to onion production and that allocated to potato farming. Results also indicate that onion yield is significantly greater than potato yield, onion selling price is significantly greater than that of potato, and the net income from onion production is far away greater than the income from potato production. It is remarkable that, in some circumstances, the authorities may prioritize and thus propose to farmers the crops that are less competitive considering their price, yield or income, if the current climatic conditions and economic settings are maintained in the medium or long term. Referring to these findings, policy efforts should encourages to the farmers to shift from potato farming to onion production, or simply inclusion of crop diversification via adopting onion may be the best option to maximize the potentials of the selected crops.

Objective. The aim of this review is to draw general lessons from several decades of empirical research on psycho-behavioural treatments for premature ejaculation. Method. Thirty-three trials reporting measures pre- and post-sex therapy were collected and assessed. Results. The improvement rates associated with sex therapies ranged from 25% to 100%, the overall effect size (d) was between 0.83 and 3.75. The effectiveness of the interventions requires penile stimulation exercises with pauses ("stop-start") and/or exercises aimed at regulating discrete components of sexual arousal ("regulatory" or "sexual-functional" approach). It is not clear whether variations involving squeezing, use of a vibratory device or a particular mode of masturbation are more effective. Exercises that focus on strengthening the pelvic muscles do not appear to be particularly effective. The most effective treatments are also those that allow for support of the beneficiaries in order to ensure an adequate integration of the therapeutic principles and to address any associated difficulties. In this respect, self-treatment formulas appear less effective. The combination of sex therapy and drug therapy generally yields better results than either of these two options alone. Conclusions. Empirical research accumulated over several decades supports the usefulness of sex therapies in the field of premature ejaculation and specifies their conditions of effectiveness. [less ▲]

We study the link between the volatility of exchange rates and interest rate differentials (IRD), motivated by the importance of currency carry trade activities in exchange rate dynamics. We examine this link by means of an extended stochastic volatility model, for which we detail an efficient estimation strategy based on Gaussian mixture sampling and a linearization of the volatility process. We apply this approach to six currency pairs over the period from January 1999 to December 2017. Our results suggest that changes in IRD affect volatility differently for low and high-interest-rate currencies. The volatility reacts strongly and positively to increases in the low interest rate, an effect consistent with the unwinding of carry trade positions. In contrast, the response to a raise in the high interest rate is negative and substantially smaller. In general, we find that the informational content of the interest rate differentials regarding the volatility of exchange rate is greater during and after the global financial crisis, compared to the pre-crisis period.

This article proposes a semio-rhetorical epistemology for visual documents, one capable of accounting for both their internal configuration, which we shall call the compositional dimension, and their persuasive force within public space, or their rhetorical dimension. The field of reference will be that of identity-related images on social networks, because compared to other kinds of images, such as artistic or professional ones, they adopt new compositional solutions and new dynamics of circulation. To test this theoretical framework, we will conduct an analysis which has never been carried out in semiotics and which, as far as we know, remains very rare even in the overall field of visual studies, that is, the analysis of the profile of an Instagram influencer’s visual production, that of Canadian artist Rupi Kaur. Taking into account the flow of images shared over time, we will focus primarily on the compositional dimension that articulates the specificity of the language of images. The most appropriate model for investigating social network photos seems to be that of the portrait, thanks to which we will identify a first series of regularities and deviations. Secondly, we will turn towards the rhetorical dimension – the persuasive strategies found within, through, and towards images – focusing on the analysis of a single photo: on the one hand, it is a shot which presents greater compositional richness than others; on the other hand, it has greatly impacted the notoriety of the influencer, due to the censorship incurred on Instagram, its abundant coverage by traditional media, and the heated debate it triggered on social media. We will thus propose a reinterpretation of Paul Ricœur’s theory of identity in order to balance the rhetorical and the compositional dimensions through a unitary theoretical hypothesis. Visual identity on social networks is always the result of a negotiation between two opposite tendencies: on the one hand, the experiential pressure expressed through images related to the body and everyday practices; on the other, the algorithmic pressure due to the delegation of the management of identity to software. The case of Rupi Kaur is a rare example of a critical mediation between these two pressures and helps us build a methodology for the examination of images belonging to other social domains. [less ▲]

Immobility and mobility are often viewed as fixed, binary opposites: one is either a migrant or a non-migrant. Yet, everyday experiences and realities elude such simple bifurcation. Non-migrants are not necessarily immobile: they frequently participate in small-scale movements and are well-engaged in social spaces that cross international borders. Similarly, migrants often engage in corporeal, material and communicative practices that anchor them to their homelands. This article applies a climate mobilities lens to a qualitative case study of an urban Senegalese fishing community, characterised by its ‘micro-mobilities’ as much as its international migration. Specifically, I take the case of Guet Ndar, Saint-Louis. Faced with rising seas, eroding coastlines, and depleting fish stocks and biodiversity, Guet Ndarians abroad and at home respond to the ensuing degradation of livelihoods and the destruction of homes by altering their mobility patterns through circular labour mobility to Mauritania, which then enables smaller-scale local movements including self-relocation via social and financial remittances. I argue that (im)mobilities are neither fixed nor all-encompassing but are rather relational and uneven – in time, space, and agency – and that environmental changes pressure people, regardless of their migration status, to redirect their (im)mobilities into new constellations.

RATIONALE & OBJECTIVE: Bone biopsy remains the gold standard for diagnosing renal osteodystrophy as comparable non-invasive alternatives have yet to be established. The aim of this study was to investigate the diagnostic accuracy of biochemical markers of skeletal remodeling to predict bone turnover. STUDY DESIGN: Cross-sectional retrospective diagnostic test study. SETTING & PARTICIPANTS: Patients with chronic kidney disease stages G4-G5D and kidney transplant recipients with successful transiliac bone biopsies. TESTS COMPARED: Bone turnover as determined by bone histomorphometry was compared to the following biochemical markers: Full-length (1-84) parathyroid hormone (PTH), bone-specific alkaline phosphatase (BsAP), intact procollagen type I N-terminal propeptide (PINP), and tartrate-resistant acid phosphatase isoform 5b (TRAP5b). OUTCOME: Diagnostic performance was evaluated by area under the receiver operator characteristics curve (AUC), sensitivity, specificity, and negative and positive predictive values. Optimal diagnostic cutoffs were determined in an exploration cohort (n=100) and validated in a separate cohort (n=99). RESULTS: All biomarkers differed across categories of low 33 (17%), normal 109 (55%), and high 57 (29%) bone turnover. AUC values were in the range of 0.75 - 0.85. High negative predictive values (≥90%) were found for both high and low bone turnover, indicating the ability to rule out both conditions using the suggested biomarker cutoffs. The highest diagnostic performances were seen with combinations of biomarkers, with overall diagnostic accuracies of 90% for high turnover, and 78% for low turnover. Results were comparable for kidney transplant candidates and recipients in a sensitivity analysis. LIMITATIONS: The single-center approach and heterogeneity of the study cohort are main limitations of this study. CONCLUSIONS: We conclude that the diagnostic performance of biochemical markers of bone turnover is acceptable, with clinical utility in ruling out both high and low turnover bone disease. [less ▲]

Aim: The aim of this case series was to evaluate the 4-year outcomes of implants placed in the aesthetic area using static computer-assisted implant surgery (s-CAIS) and restored with a one-abutment one-time (OAOT) protocol using custom-made zirconia abutments and cemented provisional crowns manufactured prior to surgery. Material and methods: Ten consecutive implants were placed in the aesthetic area. Based on a digital implant and prosthodontic planning, surgical guides were ordered and used for the preparation of definitive custom-made zirconia abutments and polymethylmethacrylate provisional crowns. Implants were placed using the s-CAIS guide, and prosthetic components were placed immediately. Implant outcomes were evaluated at the time of surgery, after 4 months and after 4 years. Results: All implants were successfully placed with s-CAIS and restored with final abutments and provisional crowns. No major prosthetic adverse events were observed. After 4 years, the implant survival rate was 100%, minor peri-implant bleeding on probing was reported, and very stable peri-implant bone levels were observed. The pink aesthetic score showed that the prosthetic components were well integrated, and the peri-implant soft tissues were stable. Conclusions: Within the limits of this case series, these results suggest that emerging digital workflows allow the manufacture of final custom-made abutments and provisional crowns prior to surgery. This individualised OAOT procedure may reduce cement-related complications and improve aesthetic outcomes by optimising soft tissue healing with prosthetic components. However, such protocols have evolved towards full digital workflows, and comparative clinical trials are needed. [less ▲]

Although early accounts emphasized its subfields along the medial–lateral axis, findings in recent decades have highlighted also the anterior-to-posterior (i.e., longitudinal) axis as a key contributor to this brain region’s functional organization. Hence, understanding of hippocampal function likely demands characterizing both medial-to-lateral and anterior-to-posterior axes, an approach that has been concretized by recent advances in in vivo parcellation and gradient mapping techniques. Following a short historical overview, we review the evidence provided by these approaches in brain-mapping studies, as well as the perspectives they open for addressing the behavioral relevance of the interacting organizational axes in healthy and clinical populations.

The literature has defined “right-wing populism” (RWP) as political organizations that oppose to democracy. Depending on the author, this opposition is institutional or value-driven. However, RWP presents itself as the defender of democracy. The literature argues that this is a symbolic discourse rooted in a strategy of “normalization” of the party. I aim to further revise this assumption by asking the question: in the discourse of the Rassemblent National (RN) in France and the Freiheitliche Partei Österreichs (FPÖ) in Austria, is “democracy” a “cosmetic term” or is the word “democracy” also ideologically loaded? I first propose to concentrate on the discursive relationship between RWP and the concept of democracy as studied in the literature. Second, I will present the methodology that were selected. Third, I will study the term “democracy” in RN and FPÖ speeches by carrying out a lexicometric analysis and a critical discourse analysis (CDA). I will then deal with different functions of the term “democracy” (cosmetic or symbolic, rhetorical or strategic and ideological) while highlighting tensions in the rhetoric. [less ▲]

This paper employs a sequential portfolio sorting procedure, called DSN, to factor size characteristics into returns. This leads to narrower portfolios than the original Fama-French (FF) ‘small’ and ‘big’ SMB components. The DSN sorting uncovers a purely seasonal part of the global size premium, due to a January effect. The stocks that are common to the FF and DSN small cap portfolios are smaller and of lower quality than those that are only retained by the FF procedure. This phenomenon supports a “tax-loss-pruning” hypothesis, in which investors discard small cap stocks with the lowest quality around the year end for tax reasons. [less ▲]

Purpose: To translate and validate the Identification of Functional Ankle Instability (IdFAI) into French. Methods: The IdFAI was translated according to international recommendations. Discriminative power, floor and ceiling effects, construct validity (including confirmatory factorial analysis (CFA)), internal consistency and test-retest reliability were measured. Standard Error of Measurement (SEM) and Smallest Detectable Change (SDC) were also calculated. Results: 160 participants were included. The IdFAI-F showed a very good test-retest reliability (ICC = 0.95). The SEM was 1.37 and the MDC was 3.79. The internal consistency was moderate (Cronbach's alpha coefficient = 0.68). The correlation between the IdFAI and the Cumberland Ankle Instability Tool (CAIT) was high (r =  0.75, p < 0.001). No floor, nor ceiling effects were observed. The CFA analyses did not confirm the factor structure proposed by the authors of the original English version. Conclusions: The IdFAI-F is a valid and reliable tool to accurately identify and measure chronic ankle instability in research and clinical settings for French-speaking individuals. [less ▲]

It is now well-established that regulatory T cells (Treg) represent a heterogeneous group of CD4+ T cells. Previous studies have demonstrated that Treg homeostasis was impacted by allogeneic hematopoietic cell transplantation (allo-HCT) and particularly so in patients with chronic graft-versus-host disease (GVHD). Here, we first assessed the ability of various Treg subsets to phosphorylate STAT5 in response to IL-2 or IL-7 stimulation in vitro. We then compared the frequencies of different Treg subtypes in healthy controls as well as in allo-HCT patients with or without chronic GVHD. The highest phosphorylated STAT5 (pSTAT5) signal in response to IL-2 was observed in the CD45RO+CD26−CD39+HLA-DR+ Treg fraction. In contrast, naive Treg were mostly less susceptible to IL-2 stimulation in vitro. Following IL-7 stimulation, most Treg subpopulations upregulated pSTAT5 expression but to a lesser extent than conventional T cells. Compared to healthy controls, allo-HCT patients had lower frequencies of the naive CD45RAbrightCD26+ Treg subpopulation but higher frequencies of the most differentiated memory CD45RO+CD26−CD39+ Treg subpopulations. Further, unbiased analysis revealed that six Treg clusters characterized by high expression of CD25, HLA-DR, and ICOS were significantly more frequent in patients with no or with limited chronic GVHD than in those with moderate/severe chronic GVHD.

The hippocampus is a plastic region and highly susceptible to ageing and dementia. Previous studies explicitly imposed a priori models of hippocampus when investigating ageing and dementia-specific atrophy but led to inconsistent results. Consequently, the basic question of whether macrostructural changes follow a cytoarchitectonic or functional organization across the adult lifespan and in age-related neurodegenerative disease remained open. The aim of this cross-sectional study was to identify the spatial pattern of hippocampus differentiation based on structural covariance with a data-driven approach across structural MRI data of large cohorts (n = 2594). We examined the pattern of structural covariance of hippocampus voxels in young, middle-aged, elderly, mild cognitive impairment and dementia disease samples by applying a clustering algorithm revealing differentiation in structural covariance within the hippocampus. In all the healthy and in the mild cognitive impaired participants, the hippocampus was robustly divided into anterior, lateral and medial subregions reminiscent of cytoarchitectonic division. In contrast, in dementia patients, the pattern of subdivision was closer to known functional differentiation into an anterior, body and tail subregions. These results not only contribute to a better understanding of co-plasticity and co-atrophy in the hippocampus across the lifespan and in dementia, but also provide robust data-driven spatial representations (i.e. maps) for structural studies.

The paper aims to produce the first-ever approach of the Goethean Morphology (GM) that reads it as the forerunner of contemporary techniques of pattern recognition, generation and exploration via natural computing and computer graphics, based on the analysis of the specific visualization techniques that ground Goethe’s morphological method. I propose to read GM as an original practice of reduction, departing from the phenomenological realm to intuit nature’s self-generating processes. In this context, the main remit of reduction is not to simplify complexity, as is usually the case in modern natural sciences, but rather to let visually emerge the autonomous processes that superintend the generation of complexity itself. In this sense, I understand Goethe’s main gesture as an attempt to comprehend the logic of nature from within, instead of merely trying to represent or mimic it. My project intend to explore the visual devices that ground the construction of Goethe’s Urtype, the key-feature to its morphological method. I understand the Urtype as a matrix capable of generating the structures of actual and virtual entities [less ▲]

Let $X$ be a nonempty set. Denote by $\mathcal{F}^n_k$ the class of associative operations $F\colon X^n\to X$ satisfying the condition $F(x_1,\ldots,x_n)\in\{x_1,\ldots,x_n\}$ whenever at least $k$ of the elements $x_1,\ldots,x_n$ are equal to each other. The elements of $\mathcal{F}^n_1$ are said to be quasitrivial and those of $\mathcal{F}^n_n$ are said to be idempotent. We show that $\mathcal{F}^n_1=\cdots =\mathcal{F}^n_{n-2}\subseteq\mathcal{F}^n_{n-1}\subseteq\mathcal{F}^n_n$ and we give conditions on the set $X$ for the last inclusions to be strict. The class $\mathcal{F}^n_1$ was recently characterized by Couceiro and Devillet \cite{CouDev}, who showed that its elements are reducible to binary associative operations. However, some elements of $\mathcal{F}^n_n$ are not reducible. In this paper, we characterize the class $\mathcal{F}^n_{n-1}\setminus\mathcal{F}^n_1$ and show that its elements are reducible. We give a full description of the corresponding reductions and show how each of them is built from a quasitrivial semigroup and an Abelian group whose exponent divides $n-1$. [less ▲]

This study presents a calibration method based on machine learning techniques to identify parameters of hardening law of aluminum alloy sheets in complex manufacturing processes. A V-shape test is designed to characterize material behavior during an incremental sheet forming (ISF) process. A series of virtual materials is first generated using three physical features observed in a standard uniaxial tensile test: initial yield stress, maximum uniform plastic strain and yield-to-strength ratio. These virtual materials are then employed in simulating the designed V-shape tests to numerically collect the material responses, such as forming forces, displacements, or their combinations. Several feed-forward neural networks (FFNNs) are developed and trained to relate the collected material responses to the relevant virtual materials. Then, the trained FFNNs were used to estimate the flow curve of AA5052-H32 sheets up to a plastic strain value of 1.0 using the experimentally measured response from the V-shape test during ISF. The FFNN-based flow curves appear to capture well the stress–strain data obtained from the uniaxial tensile test with the coefficients of determination up to 0.98. The identified flow curves are also employed to simulate the uniaxial tensile and ISF truncated cone tests. The simulated uniaxial tensile forces are in good agreement with the experimentally measured results. A maximum difference of 5% is observed in the comparison between the simulated and measured ISF loading forces in the steady-state deformations. The comparisons demonstrate the efficiency of the proposed method to characterize the plastic flow of metal. [less ▲]

Using a simple hydrothermal method, CuFe1−xMnxO2 delafossite materials are produced and investigated by means of X-ray diffraction, ultraviolet-visible reflectance measurements, and electron microscopy. Up to nominally x = 0.3, the synthesis yields delafossite material, which generally consists of both the 2H and R3 phase without any impurities. Lattice parameters and the indirect optical band gap of delafossite close to about 1.3 eV decrease upon increasing Mn content, which confirms the successful doping with Mn up to an actual Mn content of x = 0.05. The 2H phase fraction shows a pronounced and peaked dependence on Mn content with a maximum 2H mass fraction of about 27% at nominally x = 0.01, whereas the hexagonal particle morphology and the platelet size of about 500 nm as measured by both scanning and transmission electron microscopy are independent from the latter.

The problem to decide which patient-donor pairs in a kidney exchange program should undergo a crossmatch test is modelled as a two-stage stochastic optimization problem. We give an integer programming formulation of this so-called selection problem, and describe a solution method based on Benders decomposition. We extensively test various solution methods, and observe that the solutions, when compared to solutions found by recourse models, lead to an improvement in the expected number of transplants. We also investigate the computational efficiency of our approach as a function of different parameters, such as maximum cycle length and the presence of altruistic donors. [less ▲]

BACKGROUND: The identification of coronavirus disease 2019 (COVID-19) risk factors is requested to implement prevention strategies. AIM: To explore the associations between the COVID-19 incidence and malnutrition, sarcopenia, and frailty, identified as potential risk factors in previous cross-sectional studies. METHODS: Malnutrition, sarcopenia, and frailty were assessed at the last available follow-up from the Sarcopenia and Physical Impairments with Advancing Age (SarcoPhAge) cohort (i.e., the fifth year that ended in 2019) according to the Mini-Nutritional Assessment short-form, the European Working Group on Sarcopenia in Older People (EWGSOP2), and the Fried criteria, respectively. Information regarding the COVID-19 was gathered by phone calls interviews in April 2021 to measure its self-declared incidence. Adjusted Cox regressions and Kaplan-Meier curves were performed. RESULTS: The present study included 241 participants [median age 75.6 (73.0-80.6) years, 63.1% women]. Among them, 27 participants (11.2%) developed the non-fatal Covid-19. No significant increased risks of COVID-19 were observed in patients with malnutrition [adjusted HR 1.14 (0.26-5.07)] and sarcopenia [adjusted HR 1.25 (0.35-4.42)]. Nevertheless, the incidence of COVID-19 was significantly higher in frail (44.4%) than in robust participants (8.5%) [Adjusted HR 7.01 (2.69-18.25)], which was confirmed by the Kaplan-Meier curves (p < 0.001). Among the frailty syndrome components, a low physical activity level was the only one significantly associated with an increased risk of COVID-19 [adjusted HR 5.18 (1.37-19.54)]. CONCLUSION: Despite some limitations in the methodology of this study (i.e., limited sample size, COVID-19 incidence self-reported and not assessed systematically using objective measurements) requiring careful  consideration, an increased risk to develop COVID-19 was observed in the presence of the frailty syndrome. Further investigations are needed to elaborate on our findings. [less ▲]

Since its release in 1974, Thierry Zéno's Vase de Noces has been at the centre of various controversies that reveal its marginal character. Going far beyond the simple surrealist zoophile love story to which it has sometimes been reduced, the film focuses, more fundamentally, on undermining a series of pairings (e.g., high/low, pure/impure, humanity/animality), on requalifying borders and on making light of categories. After introducing Vase de Noces as a film of indeterminacy, this article will approach the feature film from the detail by first formulating some proposals relating to the motif of nausea, which itself brings into play a series of structuring oppositions and surfaces an exorbitant principle of oscillation. This introductory step sets the stage for a conceptual and analytical shift by opening the reflection to Long Live the New Flesh (Nicolas Provost, 2009), where the question of the abject plays out on another level. By making the blind spot of the analysis a point of continuity between these two absolutely different Belgian films, the article considers the complementarity of these two objects to think of a fundamental indeterminacy specific to abjection, as it was approached by Julia Kristeva in The Powers of Horror. Abjection Essay (1980). [less ▲]

Recently a new 3-group clinical classification was reported by an International Consortium to stratify CMML patients with regard to prognosis. The groups were defined as follows: 1. Myelodysplastic (MD)-CMML: WBC ≤10 x 109/L, circulating immature myeloid cells (IMC) = 0, no splenomegaly; 2. MD/MP (overlap) –CMML: WBC 10-20 x 109/L or WBC ≤10 x 109/L but IMC >0 and/or splenomegaly; 3. Myeloproliferative (MP)-CMML: WBC >20 x 109/L. By analysing EBMT Registry patients who underwent allo-HCT for CMML between 1997 and 2016, we aimed to determine the impact of this classification on transplantation outcome and to make a comparison with the conventional WHO classification (CMML-0/CMML-1/CMML-2). Patient grouping was based on the data registered at time of transplantation, with IMC replaced by peripheral blasts. Among 151 patients included in the analysis, 38% were classified as MD-CMML, 42% as MD/MP-CMML and 20% as MP-CMML. With a median survival of 17 months in the whole series, MD-CMML patients were distinguished as a low-risk group with higher CR rate at transplant and a longer post-transplant 2-year progression-free survival in comparison to others (44.5% vs 33.5%, respectively), whereas the WHO classification was superior in identifying high-risk patients (CMML-2) with inferior survival outcomes.
