Leibniz’s conception of the relativity of motion has been discussed at length for a very long time. This paper doesn’t aim to give a full solution to this question, but to contribute to the debate by clarifying how the principle of relativity is introduced, justified and used in the Dynamica. Four different principles are identified : one purely geometrical, and three (meta)physical principles, which express God’s wisdom : a principle of equivalence of hypotheses linked to the action/reaction principle, a galilean principle of relativity and a general principle which apply not only to rectilinear motions but also to circular ones. I argue that to appreciate the coherence of Leibniz’ approach, we should distinguish these principles more sharply than he himself did and pay more attention to their status : are they consequences of the definition of motion, consequences of the physical laws or necessary conditions for any physical theory ?

The aim of this contribution is to explain in a straightforward manner how Bayesian inference can be used to identify material parameters of material models for solids. Bayesian approaches have already been used for this purpose, but most of the literature is not necessarily easy to understand for those new to the field. The reason for this is that most literature focuses either on complex statistical and machine learning concepts and/or on relatively complex mechanical models. In order to introduce the approach as gently as possible, we only focus on stress-strain measurements coming from uniaxial tensile tests and we only treat elastic and elastoplastic material models. Furthermore, the stress-strain measurements are created artificially in order to allow a one-to-one comparison between the true parameter values and the identified parameter distributions. [less ▲]

A targeted CE-MS approach was developed for the chiral analysis of biologically relevant amino acids in artificial cerebrospinal fluid (aCSF). In order to achieve chiral resolution, the five amino acids (Ser, Asn, Asp, Gln and Glu) were derivatized with (+)-1-(9-fluorenyl)ethyl chloroformate ((+)-FLEC). The diastereoselectivity was found to be highly dependent on pH for all analytes and the optimized background electrolyte (BGE) consisted of 150 mM acetic acid, adjusted to pH 3.7 with NH4OH. Furthermore, a reversal of the migration order of Asp derivatives was observed. This phenomenon seems to be caused by intra-molecular interactions affecting the pKa of the second ionizable group (the side chain carboxyl). The applicability of this method was evaluated using aCSF. A solid phase extraction (SPE) protocol was developed for the selective extraction of the FLEC derivatives. A full evaluation of the matrix effect and extraction yield was performed concluding that the matrix effect is marginal and the recoveries are between 46 and 92%. The method offers adequate sensitivity (limits of detection below 1 μM). [less ▲]

This paper examines the joint effect of environmental risk and moral hazard on staging activity in venture capital financing. We show theoretically and empirically that venture capitalists face a trade-off between a) deferring and staging investments to engage in learning of the risky venture and avoid downside losses and b) committing additional funds to update the incentive of the entrepreneur. We describe this trade-off through the timing of follow-on investments and show that highly qualified entrepreneurs demand greater compensation (a larger share) than do less qualified entrepreneurs in situations of high risk.

The P1B ATPase Heavy Metal ATPase 4 (HMA4) is responsible for zinc and cadmium translocation from roots to shoots in the plant Arabidopsis thaliana. It couples ATP hydrolysis to cytosolic domain movements enabling metal transport across the membrane. Thanks to high conservation level within the P-type ATPase family, the role of the HMA4 cytoplasmic catalytic domains can be inferred from well characterized pumps. In contrast, the function of its terminal cytosolic extensions as well as the metal permeation mechanism through the membrane remains elusive. Here, homology modeling of the HMA4 transmembrane region was conducted based on the crystal structure of a ZntA bacterial homolog. The analysis highlighted amino acids forming a metal permeation pathway, whose importance was subsequently investigated functionally through mutagenesis and complementation experiments in plants. Although the zinc pathway displayed overall conservation among the two proteins, significant differences were observed, especially in the entrance area with altered electronegativity and the presence of a salt bridge/H-bond network. The analysis also newly identified amino acids whose mutation results in total or partial loss of the protein function. In addition, comparison of zinc and cadmium accumulation in shoots of A. thaliana complemented lines revealed a number of HMA4 mutants exhibiting different abilities in zinc and cadmium translocation. These observations could be instrumental to design low cadmium accumulating crops, hence decreasing human cadmium exposure . [less ▲]

Production of energy from nuclear power plants generates high-level radioactive nuclear waste, harmful during dozens of thousand years. Deep geological disposal of nuclear waste represents the most reliable solutions for its safe isolation. Confinement of radioactive wastes relies on the multi-barrier concept in which isolation is provided by a series of engineered (canister, backfill) and natural (host rock) barriers. Few underground research laboratories have been built all over the world to test and validate storage solutions. The underground drilling process of disposal drifts may generate cracks, fractures/strain localisation in shear bands within the rock surrounding the gallery especially in argillaceous rocks. These degradations affect the hydro-mechanical properties of the material, such as permeability, e.g. creating a preferential flow path for radionuclide migration. Hydraulic conductivity increase within this zone must remain limited to preserve the natural barrier. In addition galleries are currently reinforced by different types of concrete supports such as shotcrete and/or prefab elements. Their purpose is twofold: avoiding partial collapse of the tunnel during drilling operations and limiting convergence of the surrounding rock. Properties of both concrete and rock mass are time dependent, due to shotcrete hydration and hydromechanical couplings within the host rock. By the use of a hydro-mechanical coupled Finite Element Code with a Second Gradient regularization, this paper aims at investigating and predicting support and rock interactions (convergence, stress field). The effect of shotcrete hydration evolution, spraying time and use of compressible wedges is studied in order to determine their relative influence. [less ▲]

Purpose: To linguistically and cross-culturally translate the Anterior Knee Pain Scale into French and to evaluate the reliability and validity of this translated version of the questionnaire. Methods: The translation part was performed in six stages, according to international guidelines: (i) two initial translations from English to French; (ii) synthesis of the two translations; (iii) backward translations into the original language; (iv) expert committee to compare the backward translations with the original questionnaire; (v) pre-final version testing and (VI) expert committee appraisal. To validate the French version of the Anterior Knee Pain Scale, we assessed its validity, reliability and floor/ceiling effects. To do this, volunteer patients from the French part of Belgium and from France, with patellofemoral pain were asked to answer the French version of the Anterior Knee Pain Scale at baseline and after 7 days, as well as the generic SF-36 questionnaire. Results: The Anterior Knee Pain Scale was translated without any major difficulties. A total of 101 subjects aged 34.5 ± 11.4 years (58.4% of women) were included in this study. Results indicated an excellent test-retest reliability (Intra-class correlation coefficient (ICC) = 0.97, 95%CI: 0.96–0.98), a high internal consistency (Cronbach’s alpha = 0.87), a consistent construct validity (high correlations with the SF-36 questionnaire were found with domains related to physical function (r = 0.80), physical role (r = 0.70) and pain (r = 0.64)) and low or moderate correlations with domains related to mental health (r = 0.26), vitality (r = 0.32) and social function (r = 0.41). Moreover, no floor/ceiling effects have been found. Conclusions: A valid French version of the Anterior Knee Pain Scale is now available and can be used with confidence to better assess the disease burden associated with patellofemoral pain. It was successfully cross-culturally adapted into French.Implications for rehabilitationThe results on psychometric properties of the French Anterior Knee Pain Scale are comparable with six validated versions obtained for the Finnish, the Turkish, the Chinese, the Dutch, the Thai and the Persian populations.The French translated version of the Anterior Knee Pain Scale is a reliable and valid instrument for assessing the functional limitations associated with patellofemoral pain.The test–retest reliability of the French Anterior Knee Pain Scale was excellent, the internal consistency was high and the construct validity was consistent.

A cause of hypophosphatemia is phosphate wasting disorders. Knowledge concerning mechanisms involved in phosphate wasting disorders has greatly increased in the last decade by the identification of phosphatonins, among them FGF-23. FGF-23 is a primarily bone derived factor decreasing renal tubular reabsorption of phosphate and the synthesis of calcitriol. Currently, pharmacological treatment of these disorders offers limited efficacy and is potentially associated to gastrointestinal, renal, and parathyroid complications; therefore, efforts have been directed toward newer pharmacological strategies that target the FGF-23 pathway. This review focuses on phosphate metabolism, its main regulators, and phosphate wasting disorders in adults, highlighting the main issues related to diagnosis and current and new potential treatments.

Abstract Helical fibers are versatile building blocks used by Nature to improve mechanical performance and to tune local behavior of load-bearing materials. Helicoidal biocomposites are arranged in multiple layers with different fiber orientations. Such heterogeneity, not matched in synthetic materials, provides biological structures with superior properties. This is the case of the multilayer tube-like structure of the wood cell wall, where each ply features a compliant matrix reinforced by stiff helicoidal microfibrils. Here, 3D polyjet printing and computer simulations are combined to investigate wood-inspired helix-reinforced cylinders. Composites with a main layer containing helicoidal fibers, bordered by inner and outer plies having thinner fibrils are considered. It is shown how the mechanical functionalities of the synthetic structures can be programmed by varying fibers/fibrils orientation and matrix compliance. It is demonstrated that failure resistance can be enhanced by enclosing the main helicoidal layer with a minimum amount of thin fibrils oriented perpendicular to the applied load, as observed in wood. Finite element simulations are used to highlight the critical role of the matrix in load-transfer mechanisms among stiff elements. These structures have the potential to be assembled into larger systems, leading to graded composites with region-specific properties optimized for multiple functionalities. [less ▲]

It is well known that it is necessary to introduce a length scale parameter in a continuum damage mechanics model to correctly simulate strain localization. The second gradient model, a special case of kinematically enriched continua, considers an internal length parameter by taking into account the second order derivatives of the displacements in the virtual power principle. In this paper, we show that the original second gradient finite element of Chambon and co-workers can present spurious oscillations, especially for mode I crack propagation problems. After providing the plane stress second gradient constitutive law, we propose to add a penalty term in the original formulation in order to improve numerical convergence and to avoid spurious oscillations in the local variables distributions. Two numerical examples using classical damage mechanics laws, a three points reinforced concrete beam and a trapezoidal notched specimen are used to test the performance of the formulation. Parametrical studies are also shown on the influence of the penalty parameter. The problem of unrealistic damage spreading for damage values close to one, occurring often in mode I crack propagation problems, is finally discussed. [less ▲]

Workers may be exposed to pesticide residues when they enter an area that has been previously treated in order to realize different tasks (e.g. for pruning, cutting, picking, harvesting, pest scouting) or to handle a contaminated crop commodity (e.g. sorting, bundling, packing). A review of the scientific literature on workers exposed to pesticide residues during re-entry tasks provides a comprehensive view of possible exposure routes and a better understanding of the risk assessment context, threshold values and calculation methodology. Methods assessing the risk to workers health are also reported and discussed. The impact of re-entry activities on health and factors affecting workers exposure are examined. Finally, solutions and mitigation measures aiming to reduce their exposure to pesticide residues are recommended. [less ▲]

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

Objectives: To assess the occurrence of 3 major adverse outcomes of sarcopenia (ie, physical disabilities, institutionalizations and deaths) observed over a 3-year follow-up in older adults and compare the risk of these outcomes using 5 definitions of sarcopenia. Design: The study is a part of the ongoing SarcoPhAge (for Sarcopenia and Physical Impairment with advancing Age) longitudinal project. Setting and Participants: The SarcoPhAge study follows 534 community-dwelling older adults. Measures: Sarcopenia was defined as low muscle mass plus a decreased muscle function. Data on adverse outcomes were collected yearly during the annual follow-up or with a phone call. The association between baseline sarcopenia and the occurrence of undesirable outcomes was tested using the Cox proportional hazards model or a logistic regression model. Results: A total of 534 subjects were recruited into this prospective cohort (73.5 6.2 years, 60.5% female). After 3 years, 33 participants were lost to follow-up. If no association between baseline sarcopenia and physical disabilities or institutionalizations was highlighted, a higher number of deaths occurred in individuals diagnosed with sarcopenia than in those who were not diagnosed (16.2% vs 4.6%, P value <.001). The probability of death within 3 years when presenting with sarcopenia showed an approximately 3-fold increase compared to subjects without sarcopenia. Conclusion: Over a 3-year period, sarcopenia at baseline was associated with an increased risk of mortality. There were some variations in the ability of different definitions of sarcopenia to predict outcomes. [less ▲]

In his now classic essay on the « Régimes d’historicité », the French historian François Hartog (2003) has very well described the effect of globalisation, democratisation and mass consumerism on our relation with the past and thus, with heritage. In the course of the 1970’s, at a time when the ink of the Venice Charter was barely dry, postmodernity triggered a loss of collective anchoring and memory, paradoxically accompanied by an amplification of the thirst for commemorations, in the name of identity or heritage. Pierre Nora’s great endeavour « Les lieux de mémoire », fully corresponds to this « presentism » era, including aside from monuments, museum and archives, intellectual constructions such as the Larousse encyclopaedia (Nora 1989). It very well illustrates the « extension of the heritage domain » as defined by the sociologist Nathalie Heinich (2009). In our « post-monumental » era, anything can possibly become heritage, regardless of scale, of artistic qualities, of age or ontological degree – from tangible to intangible. This is a sign of times. Following the example of Nelson Goodman replacing the essentialist definitions of art with the question « When is there art ? » (Goodman 1976), we should consider focusing on a dynamic and operational definition of heritage. The question « When is there heritage ?» better correspond to contemporary cultural studies and our attempt to understand « heritagization »; it contains the idea of a performative action, implying new actors, new dynamics, new process, new research questions, new difficulties and new opportunities. And by necessity new concepts. We are far from rejecting theories from the past which provided us with effective and stimulating tools. But who could still imagine today, in the situation we described, that any system could fully encompass the heritage reality as the grand theories – Brandi, Riegl,… – succeeded to do? The repeated attempts to get the Venice charter revised from the 1970’s on (Houbart 2014), and the multiplication of thematic documents and charters are the best illustration of this impossibility. But while postmodern thinkers made us suspicious towards large systems, they also made us more modest and above all, more inclined to respect « bricolage », as a most helpful attitude after a shipwreck. We believe that the current return to a case by case approach – as promoted from the interwar period by theoreticians such as Ambrogio Annoni (1946) – often mostly relying on practical constraints such as reuse and technical performances, combined with the use of decontextualised concepts – separated articles from the Venice Charter, for example – and practices – using the Ise shrine periodical rebuilding to advocate any reconstruction project – doesn’t mean to accept a cynical relativism in answer to the cause of a capital-intensive machine. But in practice, we cannot deny that it has sometimes been the case: the clearest examples are the debates addressing the reconstruction of monuments all over Europe, based on a jumble of arguments confusing the pure mercantilism of the tourism industry or unconfessed political reasons with post-conflict identity issues or religious traditions (Monumental 2010). Reflecting on such reconstruction projects, raising questions of identity, has convinced us of the incompleteness of the toolkit we inherited from 20th century theoreticians. Though still perfectly relevant to address the issues that were already present at the time when they were elaborated, they might prove inappropriate to address new types of heritage, new concerns, new issues such as cultural tourism, inclusive approaches, modern heritage or the digital turn. In this context, we have been drawn to look at texts outside the conservation sphere, starting from ontology of art and analytical philosophy. We discovered that taking a step to the side could provide a stimulating insight on heritage conservation problems. In fact, it is not surprising that, facing what many have called a heritage inflation, some new actors could help us. Now that heritage has quitted the monuments sphere to encompass any material or immaterial reality worthy of conservation and that the expert point of view is challenged by the ones of a broad range of stakeholders, from the user to the investor, it becomes interesting to look at this reality from different points of view borrowed to a wide range of human sciences such as law, communication, aesthetics, semiotics, anthropology or philosophy, to name a few. Together with our colleague Muriel Verbeeck, we are currently gathering texts in order to propose an anthology that could complement the existing ones in helping to fill conceptual gaps and throw a reinvigorating light on new problems raising old questions. The originality of the project is to chose most texts outside the conservation world, and to address movable and immovable heritage at the same time. During our presentation, we will provide some examples of the usefulness of these new concepts, some already known by a number of conservators – such as the distinction proposed by Nelson Goodman between allography and autography (Goodman 1976) –, some not – the impact of intention on identity, based on texts by Theodore Scaltsas (1981), for example –, and will encourage the members of the committee who might be interested in this approach to contribute to the project.

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

OBJECTIVES: To translate the Sarcopenia Quality of Life (SarQoL®) questionnaire into Dutch and to evaluate the psychometric properties of the Dutch version of this questionnaire. METHODS: The translation was carried out using a 5-step process, with 2 initial translations, a merging of these 2 translations, 2 backwards translations, an expert committee review and a pretest of the questionnaire. Sarcopenia was diagnosed with the EWGSOP algorithm. The validation consisted of an examination of the discriminative power, internal consistency, construct validity, test-retest reliability and floor and ceiling effects. RESULTS: No significant problems were encountered during the translation process. A total of 92 subjects were included in the validation part of this study, 30 of which were sarcopenic. Discriminative power between sarcopenic and nonsarcopenic subjects was found for all domains and the Overall score (median overall QoL score: 67.15 vs 79.72; p=0.003). High internal consistency was found (Cronbach’s alpha=0.883), as well as good construct validity with 75% of hypotheses confirmed. Test-retest reliability was excellent (ICC=0.976; 95% CI=0.947-0.989) and no floor or ceiling effects were observed. CONCLUSION: The Dutch version of the SarQoL® questionnaire is ready for use in clinical and research applications. [less ▲]

Purpose: Previous research proposed normative data on gender- and age-specific voice acoustics for adults. Such reference values are lacking for children, particularly under the age of 6. This study was intended (1) to collect reliable normative data for the acoustic parameters of 5-year-old children’s voices, and (2) to investigate potential gender-specific differences. Study: Prospective and cross-sectional. Methods: Acoustic analyses were done on the voices of 53 normophonic children (26 girls; 27 boys) aged 5;0 to 5;11 years, using Praat software. The fundamental frequency, local jitter, local shimmer, and noise-to-harmonics ratio (NHR) were measured on the sustained vowels [a], [i], and [u]. The highest frequency, lowest frequency, and frequency range were measured using ascending and descending glissandi on the vowel [a]. Results: For the three sustained vowels, the mean fundamental frequency ranged from 255 Hz to 277 Hz, mean jitter ranged from 0.394% to 0.591%, mean shimmer ranged from 2.571% to 5.824%, and mean NHR ranged from 0.009 to 0.034. The frequency range was from 190 Hz to 750 Hz, which corresponds to 23.7 semitones. No gender difference was found, except for NHR on the vowel [a]. Conclusions: The lack of gender differences – other than for NHR on the vowel [a] – led us to propose mixed norms for 5-year-old boys and girls combined. Implications: These normative data will allow clinicians to compare children’s voice assessments to specific references in order to enhance diagnostic accuracy and measure therapy outcomes. [less ▲]

This paper studies individuals’ preference for reducing advantageous inequality in the distribution of gains and losses. Combining the inequality aversion model of Fehr and Schmidt (Q J Econ 114(3):817–868, 1999) with loss aversion à la Kahneman and Tversky (Econom J Econom Soc:263–291, 1979), we predict the relative dislike for advantageous inequality is lower when outcomes are framed as losses than when outcomes are framed as gains. We test this prediction using data from two modified dictator game experiments. Consistent with the model, we find that the amount of payoff that subjects are willing to sacrifice to increase the net payoff of others and reduce advantageous inequality is smaller under a loss frame than under a gain frame. The results also show that women are more inequality averse than men in both gains and losses. [less ▲]

Since its first appearance in the early 1960s, video game has become one of the most popular forms of entertainment in France and francophone Belgium. As for other cultural industries, the last decades have seen the emergence of multiple discourses around video game, whether they come from the media, the public or the private sphere. From the themes of violence and addiction to the perception of video game as a cultural object, this paper aims to provide a comprehensive overview of game-related discourses and representations (and their recent evolution) in Francophone Europe.

Background: The remarkable progress in the treatment of childhood acute lymphoblastic leukemia (cALL) has led to a survival rate reaching 90%. This success story is unfortunately linked to increased risk of impaired skeletal mass accumulation during childhood and adolescence, predisposing the patients to osteoporosis and pathological fractures at adulthood. Objective: This study aims at characterizing the vitamin D status and bone health biomarkers in a well-characterized cohort of cALL survivors. Results: Food frequency questionnaires reveal that (i) the total vitamin D intake varies greatly (44–2132 IU/d), (ii) only 16.8% of the participants consume vitamin D supplements, and (iii) 74% of survivors' intakes are below the Recommended Daily Intakes (400 IU/d). For the 42 participants taking vitamin D supplements, the median (2.5–97.5%iles) intake is 600 IU/d (21.2–1972 IU/d). Sixteen participants are vitamin D deficient (<30 nM) and 66 insufficient (≥30 – <50 nM). Serum 24,25(OH)2D3 concentrations are directly related to those of 25OHD3, and those of 3-epi-25OHD3 below the Lower Limit of Quantification in most samples. The participants' serum concentrations of cross-linked C-telopeptide of type-I collagen and intact amino-terminal pro-peptide of type-I collagen decrease steadily with age, leveling at adulthood, and are at all times higher in males. Conclusion: The present study shows that the prevalence of vitamin D insufficiency or deficiency is not greater in cALL survivors compared to the general Canadian population despite low vitamin D food and supplement intakes. Furthermore, there seem to be no overt imbalance in the gender- and age-adjusted serum bone turnover marker concentrations. © 2018 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism [less ▲]

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

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

Genetic diversity is essential for species persistence because it provides the raw material for evolution. For marine organisms, short pelagic larval duration (PLD) and small population size are characteristics generally assumed to associate with low genetic diversity. The ecological diversity of organisms may also affect genetic diversity, with an expected corollary that more restricted habitat and dietary requirements could lead to a reduced genetic diversity because of pronounced genetic structuring. Here, we tested whether groups of species with narrower trophic niches displayed lower genetic diversity than those with broader niches. In order to test those predictions, we used different trophic guilds (i.e. groups of species having similar trophic habits) of coral reef damselfishes in Moorea (French Polynesia) for which we determined their genetic diversity using Restriction site−associated DNA sequencing (RADseq) and their trophic ecology with stomach contents and stable isotope data. We found that pelagic feeders, i.e. the guild picking zooplankton in the water column, exhibited the lowest genetic diversity despite having the longest PLD and the largest population size. This guild had also the lowest variation in habitat characteristics and dietary composition compared to benthic feeders (i.e. those mainly grazing on algae) and the intermediate group (i.e. those feeding on zooplankton, filamentous algae and small benthic invertebrates). Our findings highlight the association between trophic ecology and genetic diversity that should be more commonly investigated in population genetics. [less ▲]

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

Considerable anecdotal evidence points to the usefulness of humor in the therapeutic process, but empirical evidence is still lacking. This study searched for an association between humor and therapy outcomes in a real-life population of 110 adult psychotherapy clients who attended at least 10 therapy sessions. Clients and their therapist evaluated the frequency and intensity of humorous events, as well as therapy effectiveness, therapeutic alliance, perceived hope and pleasure to participate in therapy sessions. We found a strong positive correlation between humor and therapy effectiveness, in both client (rs = .40; p < .0001) and therapist perspectives (rs = .37; p < .0001). The link between humor and effectiveness remained significant in more severe subgroups of clients, even though these clients reported less humor in their therapies. Further research is needed to determine if humor actually enhances therapy outcomes, or if positive outcomes trigger the occurrence of humor. [less ▲]

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

La frustration née du sentiment subjectif de privation et d’injustice est à la source du processus de radicalisation selon les principaux modèles explicatifs. Habituellement envisagée selon des sources socio-économiques de privation, on observe désormais une transformation progressive de ces causes de frustration en rapport avec la capacité d’expressions publiques d’habitus religieux identitaires qui renforcent le clivage entre le « nous » et le « eux ». Cette transformation ne concerne pas seulement les personnes déjà engagées dans un processus de radicalisation mais aussi des membres de la communauté arabo-musulmane a priori éloignés des mouvances salafistes. Du point de vue individuel, outre ce clivage identitaire dans les représentations du sujet, cette transformation risque d’induire une plus grande acceptation des processus violents comme moyens légitimes de revendication. Il pourrait en résulter une radicalisation des modes de pensées de la base des « sympathisants » en mettant en concordance le projet politique et les moyens violents, avec pour conséquence un risque de polarisation au sein de la société et de fracture accrue au sein même de la communauté musulmane.

Summary: Objectives. The Acoustic Voice Quality Index (AVQI) version 03.01 is a tool for quantitative assessment of the overall severity of dysphonia. Its computation includes six acoustic parameters, which are all carried out by the freeware Praat. It is based on the recordings of a sustained vowel and a part of a text read aloud. The psychometric qualities of this tool have been confirmed by numerous publications in various languages, including French. However, studies investigating the correlation between tools for objective vocal assessment and voice-related quality of life show inconsistent results. Hence, the aim of this study was to contribute to the debate in measuring the correlations between the AVQI 03.01 score computed on French samples and the Voice Handicap Index. Methods. The data of 78 patients was used, collected during initial vocal assessment and stored in the ENT caseload of the University Hospital of Liège. We measured the Spearman rank-order correlation between the VHI total and sub-scores and the scores computed by the AVQI 03.01 on French samples. Eventually, we measured the correlation between the diagnostic decisions (“normophonia” vs “dysphonia”) of both tools using Cramer’s phi. Results. The Spearman correlation between the AVQI 03.01 score and the total VHI score, when controlling for age, is moderate (rs = .62, p < .0001). The correlations between the AVQI 03.01 score and the functional, emotional and physical sub-scores of the VHI are similarly moderate (rs = .643, .543 and .514, respectively, p <.0001). The correlation between the diagnostic decisions (“normophonia” vs “dysphonia”) by both tools is also moderate (φ = .52, p = .000). Conclusions. This study allows to keep things in perspective: even though AVQI 03.01 scores are moderately correlated with the VHI total and sub-scores, one has to keep in mind that they measure two different things. The AVQI 03.01 assesses the overall voice quality in terms of acoustic parameters, whereas the VHI assesses the multi-determined impact on the patient’s everyday life situations. Both results should thus be equally taken into account, as part of a comprehensive vocal assessment. [less ▲]

Les mécanismes cognitifs de neutralisation morale participent à la mise en place du passage à l’acte et autorisent la réitération des comportements de violences conjugales. Ces mécanismes peuvent être appréhendés au travers des théories implicites que les auteurs développent à propos du comportement transgressif, du lien entre l’action et son effet ou dans la façon dont ils perçoivent la partenaire. L’étude a consisté à analyser les premières auditions policières de 69 auteurs présumés de violences conjugales, en aveu total, partiel, ou en absence d’aveu, afin d’envisager si certains modes préférentiels de justification et de neutralisation morale apparaissaient selon la reconnaissance ou non des faits délictueux. La grille d’analyse des auditions s’est basée sur le modèle de Ward & Keenan qui a été adapté à la thématique de la violence conjugale. 268 corpus de justification ont été dégagés des auditions et regroupés selon les différentes thématiques auxquelles une catégorie supplémentaire a été ajoutée afin de rencontrer l’ensemble des corpus.

Through a philosophical critique of the novelistic discourse, the aim is to highlight the theoretical power of novels which pay attention, in a rhetorical perspective, to the body thematic, body considered as a fundamental and fully component of a subjectivity determined by material and external structures. The New Novel, analysed first as an expression of a "sensible objectivity", gives rise to a materialist and negative dialectic and has to be understood as an immanent critique of social, political and historical structures.

Image paradoxale en ce qu’elle reste invisible au spectateur malgré sa force iconique, le photogramme trouve cependant, dans le flux qui le conduit insensiblement à la disparition, certaines zones de visibilité qui en révèlent le caractère à la fois fragile et intensif.

This paper describes a robust and efficient method to obtain the steady-state, nonlinear behaviour of large arrays of electrically actuated micromembranes vibrating in a fluid. The nonlinear electromechanical behavior and the multiple vibration harmonics it creates are fully taken into account thanks to a multiharmonic finite element formulation, generated automatically using symbolic calculation. A domain decomposition method allows to consider large arrays of micromembranes by efficiently distributing the computational cost on parallel computers. Two- and three- dimensional examples highlight the main properties of the proposed method. [less ▲]

Bodner and Richardson-Champion (2007) found a dissociative effect of test context on binary remember/know judgments about a critical set of details from a film sequence. Details of medium difficulty were more likely to be judged “recollected” when preceded by a set of difficult details than a set of easy details, but were similarly likely to be judged “familiar”. Using the same paradigm, we replicated this dissociation when participants independently rated recollection and familiarity. Our finding represents the first evidence that independent recollection/familiarity ratings can be dissociated. In contrast, previous studies using independent ratings have yielded parallel effects of variables that produce dissociative effects with binary judgments. Our discussion considers potential causes of this dissociation, whether test context influenced discrimination or response bias, and implications for interpreting subjective recognition experiences. Demonstrations that test context can affect recollection reports also have implications for designing and conducting eyewitness interviews. [less ▲]

The development of formal discourse about education and outreach within the Antarctic Treaty Consultative Meetings (ATCM), and the influence of major international activities in this field, are described. We reflect on the ATCM Parties’ approach to implementing the ambition of the Protocol on Environmental Protection to the Antarctic Treaty Article 6.1.a, to promote the educational value of Antarctica and its environment, and we examine the role of workshops and expert groups within the Scientific Committee on Antarctic Research (SCAR), the International Union for the Conservation of Nature (IUCN), and the Council of Managers of National Antarctic Programmes, that emerged in the 1990s, in stimulating discussion within the ATCM. These early initiatives were a prelude to the development and implementation of a large number of International Polar Year (IPY) education and outreach programmes. The establishment of an Antarctic Treaty System Intersessional Contact Group, and an on-line forum on education and outreach during the 2015 ATCM in Bulgaria, is a legacy of IPY and is the next step in fostering collaboration to engage people around the world in the importance and relevance of Antarctica to our daily lives.

Habitats being restored in Belgian quarries are easily invaded by non-native plant species, which can hamper the germination and development of vegetation deemed to be of high conservation value. Substrates of terraces created when mining limestone quarries could be inhospitable to native plants. However, they can provide opportunities for establishing specific vegetation, such as dry calcareous grasslands. Applying suitable mining spoils could be a cost-effective way to provide growing substrate when restoring limestone terraces. We assessed the efficacy of using mining spoils, collected on-site, as a potential growing substrate (bedding material). We tested gravely limestone (product of on-site mining activities), limestone dust (by-product), and no addition (bare limestone bedrock) to determine which was best for favoring the growth of native, dry calcareous grassland species and discourage the growth of two non-native invasive species that commonly invade altered mining sites: Buddleja davidii Franch and Senecio inaequidens DC. In a field experiment (in two quarries), we studied short-term (2 y) growth response of native and invasive species after sowing three seed mixtures of native grassland species, varying in functional diversity (and one no-sowing control treatment), all treatments subjected to competitive pressure exerted by invasive species. Percent cover of native and invasive species, species abundance and reproductive characteristics of the invasive species were monitored during 2-y. Native grasslands coverage was low on all substrate types, demonstrating how slowly calcareous grasslands species establish in such harsh substrate conditions. However, type of substrate did show a significant relationship with plant abundance, with limestone dust being the most beneficial for native species establishment (coverage). Although limestone dust appeared to be the best option for restoring grassland species to limestone quarries (based on its low cost, wide availability, and potential to support native species), it was also likely to support the two invasive species. Functional diversity of the seed mixture had no consistent effect. Our study shows the importance of identifying the most appropriate substrate to both establish calcareous grasslands and resist invasive species. This approach provides insights into developing strategies to conserve biodiversity in industrial and agricultural landscapes with limestone quarries. [less ▲]

Smart farming is one of the most diverse researches. In addition, the quantity of data to be stored and the choice of the most efficient algorithms to process are important elements in this field. The storage of collected data from Internet of Things (IoT), existing on distributed, local databases and open data needs particular infrastructure to federate all these data in order to make complex treatments. The storage of this wide range of data that comes at high frequency and variable throughput is particularly difficult. In this paper, we propose the use of distributed databases and high-performance computing architecture in order to exploit multiple re-configurable computing and application specific processing such as CPUs, GPUs, TPUs and FPGAs efficiently. This exploitation allows an accurate training for an application to machine learning, deep learning and unsupervised modeling algorithms. The last ones are used for training supervised algorithms on images when it labels a set of images and unsupervised algorithms on IoT data which are unlabeled with variable qualities. The processing of data is based on Hadoop 3.1 MapReduce to achieve parallels processing and use containerization technologies to distribute treatments on Multi GPU, MIC and FPGA. This architecture allows efficient treatments of data coming from several sources with a cloud high-performance heterogeneous architecture. The proposed 4 layers infrastructure can also implement FPGA and MIC which are now natively supported by recent version of Hadoop. Moreover, with the advent of new technologies like Intel Movidius; it is now possible to deploy CNN at fog level in the IoT network and to make inference with the cloud and therefore limit significantly the network traffic that result on reducing the move of large amounts of data to the cloud.

The main goal of this paper is to provide an integrated survey of the literature devoted to identifying the drivers of structural change, broadly defined as the process of reallocation of economic activity across the three broad sectors agriculture, manufacturing and services. Using the GGDC 10-Sector Database, this paper first presents the empirical facts associated with structural change in different regions of the world – i.e. Europe and the USA, Asia, Latin America, and Africa – then reviews four determinants of structural change: (i) changes in income, (ii) changes in relative (sectoral) prices, (iii) changes in input-output linkages and (iv) changes in comparative advantage(s) via globalization and trade.

L’analyse post-évènementielle est un dispositif de soutien collectif des équipes soignantes mis en place après chaque décès d’enfant hospitalisé. Sa méthodologie comprenant une régulation pour la médiation interprofessionnelle en séance oriente les échanges sous la forme d’analyse de pratiques. Elle permet le développement de l’acte individuel et collectif du travail. C’est une nouvelle voie de soutien liée à la créativité et l’expertise collective de l’équipe, dont la permanence du dispositif accompagne la progression dans le temps. La participation de l’équipe à l’amélioration de ses pratiques et de ses conditions d’organisation offre une ressource supplémentaire pour faire face à la souffrance liée à la relation à l’enfant et la famille endeuillée. L’article questionne alors la responsabilité institutionnelle dans le choix de dispositifs préventifs de soutien face aux situations générant de la souffrance au travail. Il s’appuie sur une expérience de 15 ans et illustre la méthode par une situation concrète. Post-event analysis is a collective support for healthcare teams put in place after each death of hospitalized child. Its methodology, including regulation for interprofessional mediation in session, guides exchanges in the form of analysis of practices. It increases the development of the individual and collective act of work. It is a new channel of support linked to the creativity and collective expertise of the team, and this device accompanies the team progress over time. The team's participation in improving its practices and organizational conditions provides an additional resource to deal with the suffering associated with the relationship with the child and the bereaved family. In the discussion, the article questions the institutional responsibility in the choice of preventive devices to support situations generating suffering at work. [less ▲]

Cette relation façonne l’identité et lui donne forme, en même temps qu’elle appelle le public à en répondre de différentes manières, et appelle par conséquent différentes formes de jugements publics.

Aside from modeling geometric shape, three-dimensional (3D) urban procedural modeling has shown its value in understanding, predicting and/or controlling effects of shape on design and urban planning. In this paper, instead of the construction of flood resistant measures, we create a procedural generation system for designing urban layouts that passively reduce water depth during a flooding scenario. Our tool enables exploring designs that passively lower flood depth everywhere or mostly in chosen key areas. Our approach tightly integrates a hydraulic model and a parameterized urban generation system with an optimization engine so as to find the least cost modification to an initial urban layout design. Further, due to the computational cost of a fluid simulation, we train neural networks to assist with accelerating the design process. We have applied our system to several real-world locations and have obtained improved 3D urban models in just a few seconds. [less ▲]

Of all the royal families of ancient or modern fame, few are as iconic as the eighteenth dynasty of pharaohs of the New Kingdom of Egypt, whose opulence and deeds we are still familiar to nearly 3,500 years after their time. Tenth pharaoh of this dynasty and father of Tutankhamun, Akhenaten (Amenhotep/Amenhotep IV) still fascinates Egyptologists and history lovers through the many questions surrounding his atypical rule. One of the most striking aspects of the so-called Amarna period concerns the representations of the pharaoh himself, very confusing compared to the traditional iconography of the New Kingdom. These intriguing portraits of Pharaoh raised a whole lot of medical assumptions, more or less substantiated. We review here the main theories developed throughout history. [less ▲]

We discuss Bayesian inference for the identification of elastoplastic material parameters. In addition to errors in the stress measurements, which are commonly considered, we furthermore consider errors in the strain measurements. Since a difference between the model and the experimental data may still be present if the data is not contaminated by noise, we also incorporate the possible error of the model itself. The three formulations to describe model uncertainty in this contribution are: (1) a random variable which is taken from a normal distribution with constant parameters, (2) a random variable which is taken from a normal distribution with an input-dependent mean, and (3) a Gaussian random process with a stationary covariance function. Our results show that incorporating model uncertainty often, but not always, improves the results. If the error in the strain is considered as well, the results improve even more. [less ▲]

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

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

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

Cet article examine comment les comédiens cristallisent leurs réseaux socio-professionnels pour réduire cette incertitude.

Ces cristallisations prennent forme autour d’une diversité d’éléments cristallisateurs, dépassant une vision exclusivement centrée sur un projet ou une personne. Ces résultats enrichissent le modèle réticulaire de création organisationnelle de Larson et Starr (1993), lui donnant un caractère plus systémique, et contribuent à la compréhension des processus d’insertion socio-professionnelle des artistes grâce au prisme de l’entrepreneuriat.

In the 1990s and the 2000s, Spain and Italy experienced a considerable growth in immigration. In just two decades, the foreign population has multiplied more than fivefold in both countries and by 2010 accounted for 12 and 6 per cent of the total population, respectively (INE, 2015; ISTAT, 2015). This demographic change has put pressure on the democratic representative system of both countries, with large numbers of new residents wishing to have a voice in the direction of collective affairs. Yet, at the same time, public opinion has become increasingly concerned about immigration and immigrants’ integration in both countries, with attitudes towards immigrants becoming increasingly negative in both. This article examines how these competing pressures can help us better understand the strategies of political parties in relation to the incorporation of citizens of immigrant origin into elected office in the national parliaments of both countries. Drawing on an original and unique dataset on the socio-demographic characteristics and political profiles of all national MPs elected in Spain and Italy since the beginning of the 1990s, this study aims at examining the dynamics which encourage or hinder the political representation of citizens of immigrant origin in these two Southern European countries.

Recently, SarQoL® (Sarcopenia and Quality of Life), a quality of life (QoL) questionnaire specific to sarcopenia, was successfully developed. For practical reasons, there is a great interest in validating this questionnaire in other populations. The aim of this cross-sectional study was to translate and adjust the SarQoL® into Polish and to standardize the validity of this method for the assessment of sarcopenic individuals in Poland with regard to psychometric properties. The English version was used for the translation process. A total of 106 community-dwelling Caucasian subjects aged 73.3 5.94 years (65.1% females) were studied, with 60 participants being diagnosed sarcopenic. The translation and cross-cultural adaptation was carried out in five phases according to specific standard guidelines. There were no major linguistic issues in the translation process. The data confirmed a good discriminant validity, i.e., significantly lower scores for all domains (reduced global QoL in sarcopenic subjects compared to non-sarcopenic ones; 54.9 16.5 vs. 63.3 17.1, p = 0.013), and high internal consistency (Cronbach’s alpha coefficient was 0.92). The significant correlation of the SarQoL® scores with those of other questionnaires (SF-36v2® Health Survey and EuroQoL-5-Dimension) that are supposed to have similar dimensions indicated the consistent construct validity of the SarQoL®-PL questionnaire. No floor/ceiling effects were found. An excellent agreement was found between the test and the re-test (intraclass coefficient correlation (ICC): 0.99). The first Polish version of the SarQoL® questionnaire is valid and consistent and therefore may be used with reliability for clinical and research purposes regarding QoL assessment of sarcopenic individuals. However, further research, in particular prospective studies, is needed to determine potential limitations and the suitability of the new tool for the Polish scenario and specificity. [less ▲]

From a survival analysis perspective, bank failure data are often characterized by small default rates and heavy censoring. This empirical evidence can be explained by the existence of a subpopulation of banks likely immune from bankruptcy. In this regard, we use a mixture cure model to separate the factors with an influence on the susceptibility to default from the ones affecting the survival time of susceptible banks. In this paper, we extend a semi-parametric proportional hazards cure model to time-varying covariates and we propose a variable selection technique based on its penalized likelihood. By means of a simulation study, we show how this technique performs reasonably well. Finally, we illustrate an application to commercial bank failures in the United States over the period 2006-2016.

Abaloparatide (ABL) is a 34-amino acid peptide designed to be a selective activator of the parathyroid hormone receptor type 1 signaling pathway. In the Abaloparatide Comparator Trial In Vertebral Endpoints (ACTIVE), subcutaneous ABL reduced the risk of new vertebral, nonvertebral, clinical, and major osteoporotic fracture compared with placebo and of major osteoporotic fracture compared with teriparatide. To further evaluate the effectiveness of ABL, we calculated the number needed to treat (NNT) to prevent one fracture using ACTIVE data. To estimate the potential effectiveness of ABL in populations at higher fracture risk than in ACTIVE, we calculated NNT for vertebral fracture using reference populations from historical placebo-controlled trials, assuming an 86% relative risk reduction in vertebral fracture with ABL treatment as observed in ACTIVE. NNT was calculated as the reciprocal of the absolute risk reduction in ACTIVE. The projected NNT for ABL in other populations was calculated based on incidence rate (IR) for vertebral fractures in the placebo arms of the FREEDOM (placebo IR 7.2%), FIT-1 (placebo IR 15.0%), and FIT-2 (placebo IR 3.8%) trials. NNT for ABL in ACTIVE was 28 for vertebral, 55 for nonvertebral, 37 for clinical, and 34 for major osteoporotic fracture. NNT for these fracture types for teriparatide in ACTIVE were 30, 92, 59, and 75, respectively. Using placebo IRs from FREEDOM, FIT-1, and FIT-2, projected NNTs for vertebral fracture with ABL were 17, 8, and 31. These data are useful for further evaluating ABL for the treatment of osteoporosis in postmenopausal women. [less ▲]

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