En 2010 les gastronomies marocaine et italienne sont inscrites ensemble sur la liste représentative du patrimoine immatériel de l’humanité par l’Unesco. Elles font partie de la "diète méditerranéenne", dont les cuisines partagent « savoir-faire, connaissances, pratiques et traditions qui vont du paysage à la table […] » . Cultures alimentaires sensiblement différentes sont ainsi rapprochées les unes aux autres par un discours qui vise à les préserver. Ce discours atteint aussi les individus ; en particulier, lorsque les appartenances culturelles se rencontrent grâce à la mobilité des groupes et de leurs pratiques, on observe comment un patrimoine fabriqué à plusieurs mains fait l’objet d’échanges concrets. L’analyse ethnographique d’un atelier de cuisine arabe organisé dans le nord d’Italie mettra en évidence les diversités et les convergences, les nuances régionales et générationnelles qui dotent ce patrimoine d’un dynamisme et d’une appartenance territoriale mobile et partagée.

Context: One in 4 men in the US aged >50 will suffer an osteoporosis-related fracture. Less data are available on osteoporosis treatment in men than women. Objective: Evaluate denosumab therapy in men with low BMD. Design: Phase 3 study with two treatment periods: a previously reported 12-month double-blind, placebo-controlled phase and a 12-month open-label phase. Setting: Multicenter in North America and Europe. Participants: 228 men entered the open-label phase and 219 completed the study. Intervention: Men from the original denosumab (long-term) and placebo (crossover) groups received denosumab 60 mg SC every 6 months. Main Outcome Measures: BMD, serum C-telopeptide (sCTX), and safety. Results: During the open-label phase, continued BMD increases occurred with long-term denosumab treatment (2.2% lumbar spine; 0.9% total hip; 1.3% femoral neck; 1.3% trochanter; and 0.2% 1/3 radius), resulting in cumulative 24-month gains from baseline of 8.0%, 3.4%, 3.4%, 4.6%, and 0.7%, respectively (all P<0.01). The crossover group showed BMD gains after 12 months of denosumab treatment similar to the long-term denosumab group during the first treatment year. Significant reductions in sCTX were observed following denosumab administration. Adverse events rates were similar between groups and no new safety signals identified. Conclusions: In men with low BMD, denosumab treatment for a second year continued to increase BMD, maintained reductions in bone resorption, and was well tolerated. BMD increased in men initiating denosumab during the second year. These effects were similar to those previously seen in postmenopausal women with osteoporosis and men with prostate cancer on androgen deprivation therapy. [less ▲]

Introduction: The Copper belt of Katanga presents huge resources of Cu and Co-ore. On the copper hills, mineralized rocks outcrop and a specific flora did develop as a response to the high levels of Cu and Co in soil. Soil-vegetation relationships need to be understood in order to elaborate biodiversity conservation programs prior to industrial mining of the copper hills. Literature: This paper reviews knowledge about soil characterization in the copper hills of Katanga and makes proposals for further research about the influence of the very specific chemical conditions of contaminated soils on the vegetation. The focus was put on the geochemical background and the bioavailability of Cu and Co. A lot of progress has been made recently about identification of soil-vegetation relationships. Conclusion: However, the issue of Cu and Co mobility within soil-plant systems is not entirely solved. [less ▲]

BACKGROUND: Signals of an increased risk of myocardial infarction (MI) have been identified with dabigatran etexilate in randomized controlled trials (RCTs). METHODS AND RESULES: We conducted searches of the published literature and a clinical trials registry maintained by the drug manufacturer. Criteria for inclusion in our meta-analysis included all RCTs and the availability of outcome data for MI, other cardiovascular events, major bleeding, and all-cause mortality. Among the 501 unique references identified, 14 RCTs fulfilled the inclusion criteria. Stratification analyses by comparators and doses of dabigatran etexilate were conducted. Peto odds ratio (ORPETO) values using the fixed-effect model (FEM) for MI, other cardiovascular events, major bleeding, and all-cause mortality were 1.34 (95% CI 1.08 to 1.65, P=0.007), 0.93 (95%CI 0.83 to 1.06, P=0.270), 0.88 (95% CI 0.79 to 0.99, P=0.029), and 0.89 (95% CI 0.80 to 1.00, P=0.041). When compared with warfarin, ORPETO values using FEM were 1.41 (95% CI 1.11 to 1.80, P=0.005), 0.94 (95%CI 0.83 to 1.06, P=0.293), 0.85 (95% CI 0.76 to 0.96, P=0.007), and 0.90 (95% CI 0.81 to 1.01, P=0.061), respectively. In RCTs using the 150-mg BID dosage, the ORPETO values using FEM were 1.45 (95% CI 1.11 to 1.91, P=0.007), 0.95 (95% CI 0.82 to 1.09, P=0.423), 0.92 (95% CI 0.81 to 1.05, P=0.228), and 0.88 (95% CI 0.78 to 1.00, P=0.045), respectively. The results of the 110-mg BID dosage were mainly driven by the RE-LY trial. CONCLUSIONS: This meta-analysis provides evidence that dabigatran etexilate is associated with a significantly increased risk of MI. This increased risk should be considered taking into account the overall benefit in terms of major bleeding and all-cause mortality. [less ▲]

Freeplay in aircraft control surface actuators is a common source of nonlinearity that can cause undesirable aeroelastic phenomena and, as a consequence, certification authorities place strict limits on the size of the deadband gaps of actuators. In recent years many authors have worked on determining the effects of freeplay on the dynamic behavior of aeroelastic systems; these efforts have yielded significant improvements in the understanding of the phenomena, but have concentrated on simple models. Investigations of industry-relevant aeroelastic models of complete aircraft with freeplay in the actuators have been much rarer, the main difficulty being the selection of an appropriate modal basis that can represent the full range of possible dynamic phenomena. This work presents a novel implementation of the residual vectors approach to create consistent and numerically stable reduced order models suitable for industrial-standard aeroelastic models of aircraft. The methodology relies on the piecewise linear nature of freeplay to create a single reduction basis that represents the dynamics of the system both inside and outside the freeplay deadband gap. The method is demonstrated on an Embraer generic test bench aircraft, showing that the resulting reduced order model is efficient and effective. Nonlinear analysis is carried out using equivalent linearization as well as time integrations of the full nonlinear system. It is shown that, while equivalent linearization is an indispensable tool for a preliminary mapping of the main aeroelastic instabilities, the time integration-based nonlinear analysis is an essential complementary tool to confirm the characteristics of the system behavior.

Capgras delusion is characterized by the misidentification of people and by the delusional belief that the misidentified persons have been replaced by impostors, generally perceived as persecutors. Since little is known regarding the neural correlates of Capgras syndrome, the cerebral metabolic pattern of a patient with probable Alzheimer’s disease (AD) and Capgras syndrome was compared with those of 24 healthy elderly subjects and 26 AD patients without delusional syndrome. Compared to the healthy and AD groups, the patient had significant hypometabolism in frontal and posterior midline structures. In light of current neural models of face perception, our patient’s Capgras syndrome may be related to impaired recognition of a familiar face, subserved by the posterior cingulate/precuneus cortex, and impaired reflection about personally relevant knowledge related to a face, subserved by the dorsomedial prefrontal cortex.

Scientists in many fields of research have developed models, theories and concepts attempting to grasp and manage dangers that are often difficult to imagine. Among the different perspectives, the Science and Technology Studies (STS) Vulnerability Approach seems very promising. Relying on a constructivist paradigm, it is based on an inductive collection and analysis of a wide range of factors, with a particular focus on cultural factors and actual day-to-day practices. In this paper, we present the roots of this approach and we display findings based on three case studies exploring emergency planning in three different contexts (a city near a SEVESO plant, a school near a nuclear plant, and a city confronted to multiple catastrophic scenarios). The cases studies were realized by conducting three Focus Groups with different types of stakeholders (citizens, teachers, firemen, decision makers, etc.). After presenting the results of the case studies, we discuss how stakeholders’ participation can inform such type of vulnerability analysis in the context of emergency planning. We argue that participation fosters a deep understanding of actual safety governance practices which allows innovative results to emerge as well as it initiates a learning process among the participants. It contributes to questioning the relations between decision-makers, experts and citizens. It has the potential of bypassing the positivist and quantitative rationale of safety, and thus, of redefining the vulnerability governance. As a conclusion, we question the role of such STS vulnerability approach within the actual vulnerability governance. [less ▲]

Genetic variability related to the catechol-O-methyltransferase (COMT) gene has received increasing attention in the last 15 years, in particular as a potential modulator of the neural substrates underlying inhibitory processes and updating in working memory (WM). In an event-related functional magnetic resonance imaging (fMRI) study, we administered a modified version of the Sternberg probe recency task (Sternberg, 1966) to 43 young healthy volunteers, varying the level of interference across successive items. The task was divided into two parts (high vs. low interference) to induce either proactive or reactive control processes. The participants were separated into three groups according to their COMT Val158Met genotype [Val/Val (VV); Val/Met (VM); Met/Met (MM)]. The general aim of the study was to determine whether COMT polymorphism has a modulating effect on the neural substrates of interference resolution during WM processing. Results indicate that interfering trials were associated with greater involvement of frontal cortices (bilateral medial frontal gyrus, left precentral and superior frontal gyri, right inferior frontal gyrus) in VV homozygous subjects (by comparison to Met allele carriers) only in the proactive condition of the task. In addition, analysis of peristimulus haemodynamic responses (PSTH) revealed that the genotype-related difference observed in the left SFG was specifically driven by a larger increase in activity from the storage to the recognition phase of the interfering trials in VV homozygous subjects. These results confirm the impact of COMT genotype on inhibitory processes during a WM task, with an advantage for Met allele carriers. Interestingly, this impact on frontal areas is present only when the level of interference is high, and especially during the transition from storage to recognition in the left superior frontal gyrus.

In birds and mammals, randomness is known to have excitatory effects on exploratory behavior, but this phenomenon has not extensively been studied in invertebrates. Four experiments examined the propensity of woodlice (Porcellio scaber) to choose between the exploration of an environment composed of random visuo-tactile patterns and the exploration of an environment composed of regular visuo-tactile patterns. Rearing-up behavior and distance traveled were measured to determine (i) woodlice’s reactivity to a forced exposure to random or regular patterns, (ii) the effect of random and regular patterns on exploratory choice, (iii) the effect of random and regular patterns on exploratory choice in preexposed animals, and (iv) the effect of a shelter available in the less explored environment on exploratory choice. The results suggest that random visuo-tactile patterns have an excitatory effect on the exploratory behavior of woodlice and that this effect develops more rapidly if the woodlice were initially preexposed to those patterns. They also suggest that exploration is related to the search for better habitat conditions because the presence of a shelter abolishes that behavior. [less ▲]

Siting controversies are commonplace, as well against the construction of roads, railways, nuclear waste disposals, as against windfarms. Local citizens resist against siting decisions taken by the authorities, following a dynamics often quoted as ‘Not In My Back Yard’. Yet contested for its lack of analytical value, NIMBY is still used strategically by actors to qualify citizens as irrational and egoistic. Beyond this labelling, many factors are investigated to understand the dynamics behind siting controversies. In this paper, we focus on the impact of the legal procedure structuring the implantation of windfarms in the Walloon Region (Belgium), and its translations within different decision making processes in specific case studies. To that regard, we consider the legal procedure as a ‘public policy instrument’. It is neither neutral nor natural, and carry values and interests. It organizes inter-personal relations between actors, and is potentially catalyzer of frustrations. In addition, this legal procedure is the object of translations within different contexts, including different actors participating to specific decision making processes. The empirical approach of this paper is based on case studies data and on the use of an innovative methodology called ‘Open Process Workshop’. This methodology consists in a structured workshop with key stakeholders, during which the legal procedure is questioned. Overall, we demonstrate that the focus on the legal procedure - and its translations within different decision making processes - allows systemic analysis providing deep understandings of controversies and reaffirming the interlinks between ‘the social’ and ‘the technical’ in such controversies. In addition, we argue that the methodology used fosters the production of innovative knowledge, mutual understanding and collective learning between the participants. [less ▲]

This study investigates the meteorological variation in revealed preference travel data. The main objective of this study is to investigate the impact of weather conditions on daily activity participation (trip motives) and daily modal choices in the Netherlands. To this end, data from the Dutch National Travel Household Survey of 2008 were matched to hourly weather data provided by the Royal Dutch Meteorological Institute and were complemented with thermal indices to indicate the level of thermal comfort and additional variables to indicate the seasonality of the weather conditions. Two multinomial logit–generalised estimation equations (MNL-GEE) models were constructed, one to assess the impact of weather conditions on trip motives and one to assess the effect of weather conditions on modal choice. The modelling results indicate that, depending on the travel attribute of concern, other factors might play a role. Nonetheless, the thermal component, as well as the aesthetical component and the physical component of weather play a significant role. Moreover, the parameter estimates indicate significant differences in the impact of weather conditions when different time scales are considered (e.g. daily versus hourly based). The fact that snow does not play any role at all was unexpected. This finding can be explained by the relatively low occurrence of this weather type in the study area. It is important to consider the effects of weather in travel demand modelling frameworks because this will help to achieve higher accuracy and more realistic traffic forecasts. These will in turn allow policy makers to make better long-term and short-term decisions to achieve various political goals, such as progress towards a sustainable transportation system. Further research in this respect should emphasise the role of weather conditions and activityscheduling attributes. [less ▲]

The submarine part of the North Anatolian Fault (NAF) in the Marmara Sea is a significant hazard for the city of Istanbul (Turkey). The use of paleoseismological data to provide an accurate seismic risk assessment for the area is constrained by the fact that the NAF system is submarine near Istanbul; thus a history of paleoearthquakes can be inferred only by using sediment cores. Here a record of turbidites was obtained in two cores and used to reconstruct the earthquake history along a main branch of the NAF, the Cinarcik Segment. Kullenberg core Klg04 (4 m long) was collected during Marmarascarps mission from a berm north of the fault and a second core (Klg03, 3.5 m long) was positioned in the Cinarcik Basin, 3 km south of the fault. Sedimentary sequences in the two cores were correlated using variations in Ca/Ti ratio, which reflect the local aquatic productivity compared with more terrigenous input. The turbidites between the two cores were then classified to distinguish the synchronous ones from the other ones. Radionuclide measurements suggest that the most recent turbidite recorded in both cores was triggered by the M=7.3 1894 earthquake. We conclude that the turbidites are earthquake-generated, based on: 1) their distinctive sedimentological and geochemical signatures, previously described and applied in the Marmara Sea; 2) the correlation of turbidites between cores at berm and basin sites; 3) the match of the most recent turbidites with a 19th century historical earthquake; and 4) the elimination of others processes. Because of its specific geomorphological location, core Klg04 likely records only mass wasting events related to the rupture on the Cinarcik Segment. To date older turbidites, we used 14C and paleomagnetic data to build an OxCal age model with a local reservoir correction (ΔR) of 400±50 yr. The Cinarcik Segment is found to have ruptured in AD1894, AD1509, sometime in the 14th century, AD989, AD740 and in the 5th century and have a mean recurrence interval of rupture between 243 and 396 years. Following the age model obtained we finally used the earthquake record history of the Cinarcik Segment to infer the rupture history of adjacent segments of the North Anatolian Fault during six earthquake cycles over the past 1500 years.

Objectives - This review studies the concept of affective security in children living outside of their family environment by a brief exposition of its practical illustration in institution. We want to show that sufficient affective security can be achieved even in children institutionalized with major attachment difficulties. Method - We will first examine the original meaning of the concept by a theoretical review of its evolution over the years in the literature. Then, we will consider various questions concerning the legitimacy of institutionalization in link with affective security through a case analysis illustrating the issue. We will finally end by mentioning the main practical implications about the optimization of affective security in children institutionalized. Results - It is foremost by the predictable and expected daily acts posed by the professional caregivers in institution that the child may find sufficient affective security, generating emotional well-being and ultimately, an overall adequate development. Discussion – Children early separated from their family home to be placed in residential institution most often suffer from serious difficulties in terms of attachment to others. In this context, the institution has to deal with a specifically challenge: that is, to help the child to (re-)find sufficient internal security to allow him to grow on solid foundations. The institutional life which replaces family life primarily consists of an organizational structure that seeks to make child life as predictable as possible so that it has the necessary daily benchmarks to evolve adequately. Conclusion – In the everyday life in institution, the professionals struggling with children’s attachment disorders constantly try to achieve a right emotional-body balance through their psycho-educational practices with the child deprived of secure attachment strategies.

Urban sprawl is transforming our landscapes and rural areas at a spectacular pace. Measuring the strength of the phenomenon and proposing dynamic ways to delineate suburban areas have been the object of much debate amongst scientists. The present article takes the view that, beyond measuring and delineating suburban areas, more efforts should be directed to qualifying the morphology of built settlements within these areas. Therefore it proposes a method based on a semi-automatic classification system of building clusters, designed to describe and interpret the phenomenon from a morphological perspective. This method is based on a combination of field surveys with numerical analyses of digital land cadastre maps. The application of this classification system to the suburban area around Liege reveals that, far from developing in a complete indifference of local conditions, contemporary suburban settlements are influenced by landscape structures inherited from the past.

Acute cardiorenal syndrome (CRS) corresponds to an association of acute heart failure and a worsening of renal function. The detection of acute kidney injury (AKI) unfortunately occurs at a late stage of CRS, leading to an increased mortality of the patients. In this review, we described the pathophysiology of CRS and discussed the potential interest of biochemical biomarkers (namely creatinine, cystatin C, NGAL, KIM-1, fatty acid binding protein, Nacetyl-β-D-glucosaminidase and IL-18) that could potentially help to detect AKI earlier and thus reduce the morbi-mortality of the patients suffering from CRS.

We investigated the accuracy of auditory inferences of personality of Belgian children with vocal fold nodules (VFN). External judges (N=57) were asked to infer the personality of normophonic (NP) children and children with VFN (N=10) on the basis of vowels and sentences. The auditory inferred profiles were compared to the actual personality of NP and VFN children. Positive and partly accurate inferences of VFN children’s personality were made on the basis of connected speech, while sustained vowels yielded negative and inaccurate inferences of personality traits of children with VFN. Dysphonic voice quality, as defined by the overall severity of vocal abnormality, conveyed inaccurate and low degrees of Extraversion. This effect was counterbalanced in connected speech by faster speaking rate that accurately conveyed higher degrees of Extraversion, a characteristic trait of VFN children’s actual personality.

The influence of substrate hydrophobicity and biomacromolecules (dextran, bovine serum albumin - BSA) adsorption on the cleanability of surfaces soiled by spraying aqueous suspensions of quartz particles (10 to 30 µm size), then dried, was investigated using glass and polystyrene as substrates. The cleanability was evaluated using radial flow cell (RFC). The surface composition was determined by X-ray photoelectron spectroscopy (XPS). The interpretation of XPS data allowed the complexity due to the ubiquitous presence of organic contaminants to be coped with, and the surface composition to be expressed in terms of both the amount of adlayer and the mass concentration of adlayer constituents. When soiled with a suspension of particles in water, glass was much less cleanable than polystyrene, which was attributed to its much lower water contact angle, in agreement with previous observations on starch soil. Dextran was easily desorbed and did not affect the cleanability. The presence of BSA at the interface strongly improved the cleanability of glass while the contact angle did not change appreciably. In contrast, soiling polystyrene with quartz particles suspended in a BSA solution instead of water did not change markedly the cleanability, while the contact angle was much lower and the aggregates of soiling particles were more flat. These observations are explained by the major role of capillary forces developed upon drying, which influence the closeness of the contact between the soiling particles and the substrate and, thereby, the adherence of particles. The capillary forces are proportional to the liquid surface tension and depend in a more complex way on contact angles of the particles and of the substrate. The dependence of cleanability on capillary forces, and in particular on the liquid surface tension, is predominant as compared with its dependence on the size and shape of the soiling aggregates, which influence the efficiency of shear forces exerted by the flowing water upon cleaning.

A systematic study on the presence of bottlenose dolphins (Tursiops truncatus) in the Río Negro Estuary (RNE), Patagonia Argentina, was carried out between the months March – July from 2008 to 2011. Data on the dolphin’s activity patterns were gathered via an Ad Libitum focal group sampling mode accompanying dorsal fin images taken for identification and re-identification of individuals. A total effort of 188 h resulted in 58 h of positive observation of 124 dolphin groups (sightings per unit effort (SPUE) = 0.66 groups/h). Data analysis showed two main activity states for the observed groups, travelling (65%) and foraging (26%). The remaining 9% of the groups were involved in other activity states. The photo-identification effort, which started opportunistically in 2006, resulted in a catalogue of 21 individual dolphins, with a total mean re-identification rate of 9 days (max = 24 days). When comparing these pictures to the existing catalogue of Bahía San Antonio (approximately 200 km west from the study area) dorsal fins of 20 individuals could be positively matched and most (n = 17) could be subsequently re-identified in both areas, indicating their long distance movements along the North Patagonian coast during the austral autumn months. This season coincides with the lowest amount of feeding activity observed in Bahía San Antonio. This study suggests that bottlenose dolphins enter RNE, mainly during autumn, to forage. It appears that the search for food resources may be the trigger for their movement patterns along the North Patagonian coast during this season, at least for certain individuals. More research is needed to accurately confirm this hypothesis. [less ▲]

Pneumocystis fungi represent a highly diversified biological group with numerous species, which display a strong host-specificity suggesting a long co-speciation process. In the present study, the presence and genetic diversity of Pneumocystis organisms was investigated in 203 lung samples from woodmice (Apodemus sylvaticus) collected on western continental Europe and Mediterranean islands. The presence of Pneumocystis DNA was assessed by nested PCR at both large and small mitochondrial subunit (mtLSU and mtSSU) rRNA loci. Direct sequencing of nested PCR products demonstrated a very high variability among woodmouse-derived Pneumocystis organisms with a total number of 30 distinct combined mtLSU and mtSSU sequence types. However, the genetic divergence among these sequence types was very low (up to 3.87%) and the presence of several Pneumocystis species within Apodemus sylvaticus was considered unlikely. The analysis of the genetic structure of woodmouse-derived Pneumocystis revealed two distinct groups. The first one comprised Pneumocystis from woodmice collected in continental Spain, France and Balearic islands. The second one included Pneumocystis from woodmice collected in continental Italy, Corsica and Sicily. These two genetic groups were in accordance with the two lineages currently described within the host species Apodemus sylvaticus. Pneumocystis organisms are emerging as powerful tools for phylogeographic studies in mammals [less ▲]

In 1994, during the International Conference on Population and Development convened by the United Nations in Cairo, a shocking video was shown, realized by an operator of CNN and depicting the circumcision of a ten-year-old child living in this very same city. Discourses around female circumcision were not new in Egypt and in the international community, but what was considered as a new episode of a recurrent scandal (not the last one indeed) led to enhance the "war against bad government"[1]. A war fought by means of ideological weapons produced by expert knowledges among which the medical and the feminist ones. The assignment of a value to the state of integrity of the female body and to the women freedom of choice, both designed according to Western canons, led to different actions to “save” Egyptian women. In this context, development agencies fosters a widespread representation of the victim, constituted by the woman mutilated body. Such representation is functional to put in place programs which do not guarantee a freedom of choice, but rather require adherence to another female model, one that defines the "modern" woman. My article, based on ethnographic experience, aims at highlighting the complexity of such dynamics and the role played by humanitarianism within them. Female body becomes the arena where local and international economic powers operate, disregarding a real understanding of the practice, its meanings and its eventual change. ________________________________________ [1] Foucault, Michel.

The paper first distinguishes ritual action for sovereigns, which integrates the honoured rulers at a practical level within the religious life of a community, from other, more discrete configurations of the relation between royal and divine power. Among these trends, focus is on the rhetorical and spectacular dimension of wonder. The strategies of wonder-making are first studied in theory through paradoxography, then the categories of grandeur, exoticism and technical excellence are identified in action in Alexandrian religious life and festivals. Master of an empire with universal claims and collector of everything that is beautiful, rare and precious in the world, the king distances himself from his subjects in order to make his superior status explicit. Distance is, however, only the premise for the king to manifest himself to the great public through epiphanies that can be compared with those of divine power. The paper also discusses the way the conformism of court elites not only satisfied their own need to claim for distinguished social status, but also helped royal message spread and caused loyalty to it.

Urban sprawl is transforming our landscapes and rural areas at a spectacular pace. Measuring the strength of the phenomenon and proposing dynamic ways to delineate suburban areas have been the object of much debate amongst scientists. The present article takes the view that, beyond measuring and delineating suburban areas, more efforts should be directed to qualifying the morphology of built settlements within these areas. Therefore it proposes a method based on a semi-automatic classification system of building clusters, designed to describe and interpret the phenomenon from a morphological perspective. This method is based on a combination of field surveys with numerical analyses of digital land cadastre maps. The application of this classification system to the suburban area around Liege reveals that, far from developing in a complete indifference of local conditions, contemporary suburban settlements are influenced by landscape structures inherited from the past.

Intra-luminal fluid and excessive abnormal hyper-edema are regularly used for the diagnosis of endometritis in the mare, which is routinely confirmed by the presence of neutrophils on endometrial smears. Studies show a relation between neutrophils and myeloperoxidase (MPO), an enzyme contained in and released by neutrophils during degranulation or after cell lysis. This enzyme has been found in many fluids and tissues and associated with different inflammatory pathologies in the horse. The aims of this study were to assess the presence and concentration of MPO in the equine uterus, and to investigate its relation with neutrophils, and other clinical signs of endometritis. Mares (n=51) were evaluated for presence of intra-luminal fluid and excessive endometrial edema before breeding, and a small volume lavage and cytology samples were obtained. From 69 cycles, supernatant of the uterine flushes was analysed with a specific equine MPO ELISA assay to measure MPO concentration. Cytology samples were used for the diagnosis of endometritis. MPO was present in the uterus of all estrus mares in highly variable concentrations. MPO concentrations were significantly (p<0.05) higher in samples with positive cytologies and in presence of intra-luminal fluid. Occasionally, some samples with negative cytologies showed high MPO concentration, but the opposite was never observed. Cycles presenting hyper-edema weren’t associated to high concentration of MPO, intra-luminal fluid or positive cytology making it a poor diagnostic tool of endometritis. [less ▲]

This article emphasizes the impacts of international migration on ageing processes and norms within transnational families, and, specifically, analyses the roles of the zero generation, defined as the parents of first-generation migrants (Nedelcu 2009), both as non-migrant counterparts to their children abroad and as ageing migrants themselves. Transnational caregiving research has demonstrated that for many migrants and their families care arrangements must be negotiated across national borders, yet the agency of transnational older adults has been largely neglected. Based on qualitative fieldwork conducted from 2011 to 2013 in Liège, Belgium and Oujda, Morocco, the present article examines the circulation of care between Moroccan adult migrants and their ageing ascendants. This article exposes the duality of migrants’ ascendants as care givers and recipients, asserting firstly, that receiving care is not synonymous with passivity, and that, secondly, migrants’ ascendants are also the initiators of transnational practices. In both roles, this article underlines mobility as a strategy used by migrants’ parents to maintain family solidarity across national borders, but that this care mobility is limited by macro-level migration policies, here exemplified by the Belgian migration regime.

An experiment was carried out investigating the colonization ability and specific pattern of copepods towards a provisional benthic habitat. Since copepods are known to disperse passively and actively, the experiment aimed to investigate the pool of colonizers of macrophytodetritus and the species-specific active colonization pathways. The experiment was performed in a Mediterranean seagrass Posidonia oceanica meadow on defaunated macrophytodetritus accumulations (mainly dead seagrass leaves) for two time intervals (24 h and 96 h). Active colonization by copepods, independently of their adjacent potential source pool habitat (bare sandy sediments, P. oceanica canopy, water column and macrophytodetritus) occurred within 24 h. Natural densities (as in the control treatments) were only reached by active colonization through the water column. Both neither diversities nor species composition of natural macrophytodetritus were ever reached by one single migratory pathway, therefore only a combination of interstitial migration and water column migration can explain the species occurrence under natural condition. Moreover, every potential adjacent source pool habitat, contributed species to the newly colonized macrophytodetritus. However, the main colonizers were mostly species with good swimming capabilities. The diverse pool of species present in the newly colonized macrophytodetritus underlines the complex communities and dispersion capabilities of copepods. Hence, macrophytodetritus possesses the potential ability to be a colonizer source pool for every adjacent habitat and thus behaves as a copepod hub for the entire seagrass ecosystem. [less ▲]

Much contemporary images of black women in Italian media are marked by the legacy of colonialist propaganda and tend to perpetuate a representation of black women as passive eroticized objects of the white male gaze. In this sense, Ponzanesi’s call for ‘new and less biased representations, which could help to assess the multiple subject positions that black identities now occupy’ (2005: 179) is still relevant. This article responds to this call by analyzing two Nigerian video films that thematize migration and prostitution trafficking in Italy. By highlighting the complexity of the processes of ‘subjectivation’ taking place throughout the migratory process, these videos invite their viewers to look at the postcolonial subject’s responsibility in shaping the world in which s/he lives, and offer a representation of the black female subject able to go beyond the voyeuristic attitude that characterize much of the existing contemporary Italian visual culture about this topic.

The impact of pubertal development on the psychological and social functioning of the teenager arouses a particular interest; the most recent research shows the existence of complex relationships between pubertal development and the manifestation of internalized and externalized disorders. Two predominant hypothesis are used for explain influence of pubertal timing on problem behaviors : the maturational deviance theory and the stage termination (early timing) theory. The deviance theory claims that the borderline or abnormal pubertal timing, whether early or late, causes difficulties for adolescent adaptation. The early timing theory suggests that early pubertal timing and the consequent early physical maturation put adolescents at greater risk of adjustment problems because early pubertal maturation interferes with normal progression through the developmental tasks of adolescence. Our study is interested specifically in the links between delinquency during adolescence and pubertal maturation in a population of 141 boys aged between 12 and 18. We measured the pubertal variable starting from the perceived pubertal timing (PPT), which evaluates the teenagers' perception of their pubertal maturation, compared with that of their peers, to understand its impact on various dimensions of the functioning of teenagers: the self-perception (scale of Harter), aggressiveness (scale of Buss and Perry), association with peers and self-reported delinquency (attacks on property and individuals). We began with univariate analyses in order to determine the variables associated with early or late pubertal timing through comparison of scores obtained in those subjects with reference to average maturers. Subsequently, multivariate analyses were used in an attempt to sort out which among the studied factors could be predictor or a determinant of delinquency in relation to pubertal timing. Therefore, stepwise multiple regression analysis was performed. Statistical analyses were run with the SAS software, version 9.1.Our results support the thesis of precocity, the teenagers with an advanced PPT present scores of delinquency and aggressiveness significantly higher than teenagers with a standard PPT. However, the sub-group of teenagers with delayed PPT present raw scores of self-revealed delinquency which are higher than those of teenagers with a standard PPT. These teenagers can be characterized by a significantly higher hostility than the teenagers with a standard PPT. This cognitive dimension of aggressiveness, as evaluated by Buss and Perry, characterizes the functioning of the teenagers with the delayed PPT, who also present poorer self-esteem and dissatisfaction with their physical appearance. On the basis of this assessment, an analysis of multiple regression within each type of PPT aimed at identifying the variables likely to explain the delinquency of teenagers according to their PPT. The results show that the physical factor of aggressiveness is common to the three types of PPT. It is associated with the affiliation with delinquent peers for those teenagers with advanced and normal PPT, whereas for those teenagers with delayed PPT, it interacts with the factor of hostility, which is specific to them. Association with delinquent peers recognized as a major risk factor and predictive for the self-revealed delinquency of teenagers in general does not intervene for these boys who perceive their pubertal development late, compared to the others. The delinquency of teenagers with a delayed PPT cannot be explained by the factors that are considered in the general population, their social functioning and the socialization of these teenagers with delayed puberty is different from that of the other teenagers, as is their implication in delinquency, which is not explained by a kind of socialization with delinquent peers. These results confirm the importance of integrating the puberty variable into research on delinquency, but also at the level of intervention. [less ▲]

At T0, 30% of the population presented 25(OH)D serum levels below 20 ng/mL. In the VTD-treated group, mean serum levels increased from 21.2 ± 8.2 to 30.6 ± 8.8 ng/mL (𝑃 < 0.001) at T3mo and to 36.0 ± 9.2 ng/mL (𝑃 < 0.001) at T6mo. Despite documented VTD intake, no changes in serum levels were, however, observed in 10% of the treated group. In the placebo group, mean 25(OH)D serum levels decreased from22.8 ± 8.5 to 14.0 ± 6.9 ng/mL at T3mo (𝑃 < 0.001) but returned to values not significantly different from those observed at T0 (23.5 ± 8.6 ng/mL) at T6mo. No difference between serum calcium levels was observed between the groups throughout the study. In conclusion, monthly supplementation with50,000UIofVTDinwinter canwarrant serum25(OH)Dlevels above 20ng/mL in96.2%of thosehealthy young adultswithout inducing unacceptably high 25(OH)D concentration.

Besides being known for population overcrowding, prison staff strikes, and prisoner suicides or escapes, which are frequently reported by the press, prison might also be a place for rare innovative projects. One such project can be seen in a penitentiary policy initiated in Belgium in 2000 aimed at re-shaping the culture of detention towards a culture of ‘restorative justice’. What can be said of this attempt at introducing the concepts of victim, restoration, responsibilization, sensitizing and awareness within prison walls? The present article proposes an illustrative and interpretive account of this prison policy. Rather than restoring the broken victim-offender relationship, its implementation has something to do with detainees working on their ‘self’. [less ▲]

The Childhood Executive Functioning Inventory (CHEXI) is a new rating instrument for executive functioning developed by Thorell and Nyberg (2008). Through exploratory factor analyses, this inventory has been shown to tap into working memory and inhibition-related behaviors in young children. In this study, we present the psychometric characteristics of the French adaptation of the CHEXI in 8- to 11-year-old children. In addition, we explore the cross-cultural validity of the CHEXI in discriminating between children with ADHD and normally developing children in two culturally different samples (Belgian and Swedish). Confirmatory factor analyses replicated the two-factor solution, referred to as inhibition and working memory, that was identified in the original study with Swedish children. Supplementary analyses indicated that both subscales have good psychometric properties. From a clinical point of view, the CHEXI was found to discriminate, with high sensitivity and specificity, between children with ADHD and normally developing controls in both cultural samples. Cross-cultural clinical implications are discussed. [less ▲]

Although a great number of studies has already been devoted to the topic of sacred trees in Greco-Roman Egypt, this paper aims at offering a new contribution to this debate by shifting the focus of research from the hitherto dominant interest in ancient and modern botanical classifications to the study of the socio-cultural contexts (and their diachronic changes) in which sacred trees were used in Hellenistic and Roman Egypt. The analysis focuses on the case study of the tree called περσ(ε)ία / persea in Greek and Latin sources. After drawing attention to the non-complete overlap between the denomination adopted by Greek and Latin authors for this Egyptian sacred plant and its “emic” Hieroglyphic / Demotic correspondents, ἰšd and šw3b, the focus will be on patterns of continuity, innovation and re-contextualization of Egyptian religious traditions in Ptolemaic and Roman Egypt and on the social actors and contexts that were involved in the use and protection of sacred plants. When approached from this perspective, the evidence on persea provides a fruitful dossier to investigate some aspects of the dialectic between continuity and transformation in cultural traditions, with particular regard to cases where traditions were adapted beyond cultural and ethnic limits. Moreover, the persea dossier enables us to discuss ancient contexts in which, for religious reasons, nature was seen as worth of being protected and preserved against the risk of extinction. This will allow us to raise some preliminary questions concerning the limits of applicability of modern environmental thinking to ancient cultures, in contexts in which the preservation of vegetal species was seen as an important value for the identity of a community, thus requiring individual and institutional commitment.

The strength of thin-walled stainless steel columns has been investigated extensively over the past few years. In European standards, the concept of section classification for determining the cross-section capacity is used. In this system, for Class 4 cross-sections, the Effective Width Method (EWM) must be used to account for the effect of local buckling. Because of the complexity and limitations of this method, other methods have been developed, such as the Direct Strength Method (DSM) for cold-formed thin-walled profiles and the Continuous Strength Method (CSM), initially established for members made of nonlinear metallic materials. In the CSM, to take advantage of strain hardening, a deformation-based design approach employing a continuous relationship between the cross-sectional slenderness and the cross-sectional deformation capacity is used. To a large extent, the CSM yield accurate predictions, especially in the low slenderness range where the current DSM design procedures for members submitted to pure compression tends to produce conservative predictions, for materials with pronounced strain hardening such as stainless steel alloys. The present paper presents an extension of the traditional DSM which provides accurate design strength predictions in the low slenderness range for stainless steel thin-walled section columns failing by distortional, local and overall buckling. It contains practical information concerning the reference experimental data and draws conclusions about the justification of the proposed analytical formula. The paper is divided into three main parts: the description of the database, the establishment of the design model and a reliability analysis of the method. [less ▲]

Despite a rapid growth and an ongoing need for outplacement services, little is yet known about the perceived adequacy and benefits of these services for redundant employees using them. We surveyed 360 Belgian redundant employees (i.e., clients) using outplacement services provided by a public employment agency. The results indicate that an outplacement experience perceived as adequate for clients fosters their overall impressions of justice towards the dismissing organization; this leads in turn to benefits for them: reduction of negative emotions, enhancement of their perceived well-being, future perspectives, and job-seeking activities - confirming the mediating role of overall justice.

This work presents development of statistical shape models based on robust and rigid-groupwise registration followed by pointset non-rigid registration. The main advantages of the pipeline include automation in that the method does not rely on manual landmarks or a regionalization step; there is no bias in the choice of reference during the correspondence steps and the use of the Probabilistic Principal Component Analysis framework increases the domain of the shape variability. A comparison between the widely used Expectation Maximization- Iterative Closest Point algorithm and a recently reported groupwise method on publicly available data (hippocampus) using the well-known criteria of generality, specificity and compactness is also presented. The proposed method gives similar values but the curves of generality and specificity are superior to those of the other two methods. Finally the method is applied to the human scapula, which is a known difficult structure, and the human humerus. [less ▲]

Ni–Cu/SiO2 xerogel catalysts have been synthesized by cogelation of industrial tetraethoxysilane (Dynasil) and chelates of Ni and Cu with industrial 3-(2-aminoethylamino)propyltrimethoxysilane (Dynasylan DAMO) in industrial ethanol denatured with diethyl phthalate. Despite the use of industrial grade reagents, highly dispersed bimetallic Ni–Cu/SiO2 xerogel catalysts were obtained. These samples are composed of completely accessible Ni–Cu alloy crystallites with sizes of 1.6–3.4 nm located inside silica particles exhibiting a monodisperse microporous distribution. It appears that the bimetallic complex acts as a nucleation agent in the formation of silica particles. The combination of results obtained from the calculation of the metal ratio in catalysts, H2 chemisorption and transmission electron microscopy allowed calculating the surface composition of the nickel–copper particles in Ni–Cu/SiO2 cogelled xerogel catalysts. Values obtained indicate a very pronounced surface enrichment with copper. While 1,2-dichloroethane hydrodechlorination over pure nickel mainly produces ethane, increasing copper content in bimetallic catalysts results in an increase in ethylene selectivity. The specific consumption rate of 1,2-dichloroethane decreases when copper loading increases. The turnover frequency, that is, the number of catalytic cycle per active site (nickel atom and its surrounding copper atoms) and per second, seems to be independent of surface composition of alloy particles.

Dans le vaste champ de l’aide et des soins à l’égard de l’enfant et de l’adolescent, les questions liées au diagnostic transcendent souvent les aspects de prises en charge et de liens thérapeutiques ainsi que les multiples échanges entre professionnels concernés. Le diagnostic pédopsychiatrique est un processus dynamique, modifiable et momentané, les organisations pathologiques étant pour la plupart en transformation permanente. De manière spécifique et en fonction du processus développemental, la thématique du diagnostic en pédopsychiatrie renvoie plus à la question du risque évolutif qu’à la question d’un état pathologique en soi. Les aspects de la continuité des troubles mentaux de l’enfance à l’âge adulte représentent en effet un véritable enjeu développemental. Deux points de vue s’opposent dans la littérature. Le premier, en lien avec un prédéterminisme, estime que les trajectoires sont toutes tracées, l’incertitude reposant dans le diagnostic ; concrètement, il s’agit de repérer de manière précoce des individus à risque parce qu’ils sont porteurs d’un trouble qu’il faut traiter. Le second point de vue considère que les trajectoires ne sont pas déterminées mais sont en réécriture permanente ; ici, le risque ne se situe plus au niveau du diagnostic mais du pronostic, dans un souci de prévention et non de prédiction. L’article propose les réflexions de quatre cliniciens psychiatres infanto-juvéniles sur cette thématique, à la lumière de leur pratique et de leurs échanges. [less ▲]

Chronic kidney disease is frequent and usually responsible of mineral and bone disorder. These abnormalities lead to increased morbidity and mortality. To become active, native vitamin D needs a first hydroxylation in the liver, and a second one in the kidney. Next to its action on bone metabolism, vitamin D also possesses pleiotropic actions on cardiovascular, immune and neurological systems as well as antineoplastic activities. End-stage renal disease (ESRD) is also associated with a decrease in vitamin D activity by mechanisms including the increase of plasma phosphate concentration, secretion of FGF- 23 and decrease in 1a-hydroxylase activity. The prevalence of 25 hydroxy-vitamin D deficiency depends on the chosen cut-off value to define this lack. Currently it is well established that a patient has to be substituted when 25 hydroxy-vitamin D level is under 30 ng/mL. The use and monitoring of 1.25 hydroxy-vitamin D is still not recommended in routine practice. The goals of vitamin D treatment in case of ESRD are to substitute the deficiency and to prevent or treat hyperparathyroidism. Interest of native vitamin D in first intention is now well demonstrated. This review article describes the vitamin D metabolism and physiology and also the treatment for vitamin D deficiency in ESRD population. [less ▲]

This study aims to highlight what benefits, if any, Google Scholar (GS) has for academic literature searches in the field of geography, compared to three commercial bibliographic databases: Web of Science (WoS) and FRANCIS (multidisciplinary databases) and GeoRef (specialized in geosciences). To ensure a valid comparison, identical bibliographic searches were applied using each of the four bibliographic tools. To exclude automatic variations of the ten keywords tested, they were placed between quotation marks and searched only in the “title” field of the respective search tools’ interfaces. The results were limited to bibliographic references published from 2005 to 2009. In order to assess the repeatability of the results, the exact same process was repeated monthly between November 2010 and July 2011. Initially the whole set of results was analyzed, after which the search results for two keywords (selected since they yielded a manageable number of results) were studied in more detail. The results indicate that GS search results show a large degree of overlap with those of the other databases but, moreover, yield numerous unique hits, which should be useful to researchers in both the fields of human and physical geography. GS leads the other tools widely on number of results, independently of keyword, subfield, year of publication, or time of search. [less ▲]

Purpose Recent studies have suggested that metabolic factors (obesity, diabetes, hypertension and dyslipidemia) and their clustering in metabolic syndrome (MetS) might be involved in the pathophysiology of knee osteoarthritis (OA). We investigated their impact on radiographic progression by an annualised measure of the joint space narrowing (JSN) of the medial tibiofemoral compartment. Methods 559 patients older than 50 years with symptomatic knee OA were recruited for the placebo arm of the SEKOIA trial. The presence of diabetes, hypertension and dyslipidemia was determined at baseline interview. BMI was calculated, obesity was considered >30 kg/m2. MetS was defined by the sum of metabolic factors ≥3. Minimal medial tibiofemoral joint space on plain radiographs was measured by an automated method at baseline and then annually for up to 3 years. Results The mean age of patients was 62.8 [62.2-63.4] years; 392 were women. A total of 43.8% was obese, 6.6% had type 2 diabetes, 45.1% hypertension, 27.6% dyslipidemia and 13.6% MetS. Mean annualised JSN was greater for patients with type 2 diabetes than without diabetes (0.26 [-0.35 - -0.17] vs. 0.14 [-0.16 - -0.12] mm; p=0.001). This association remained significant after adjustment for sex, age, BMI, hypertension and dyslipidemia (p=0.018). In subgroup analysis, type 2 diabetes was a significant predictor of JSN in males but not females. The other metabolic factors and MetS were not associated with annualised JSN. Conclusion Type 2 diabetes was a predictor of joint space reduction in men with established knee OA. No relationships were found between MetS or other metabolic factors and radiographic progression.

Since the adoption of the ICH Q8 document concerning the development of pharmaceutical processes following a Quality by Design (QbD) approach, there have been many discussions on the opportunity for analytical procedure developments to follow a similar approach. While development and optimization of analytical procedure following QbD principles have been largely discussed and described, the place of analytical procedure validation in this framework has not been clarified. This article aims at showing that analytical procedure validation is fully integrated into the QbD paradigm and is an essential step in developing analytical procedure that are effectively fit for purpose. Adequate statistical methodologies have also their role to play: such as design of experiments, statistical modelling and probabilistic statements. The outcome of analytical procedure validation is also an analytical procedure Design Space and from it, control strategy can be set. [less ▲]

Charged nanofibers were prepared by electrospinning (ESP) poly(ε-caprolactone) with a copolymer bearing carboxylic acid functions. The presence of these functions allowed exposing some negative charges on the fiber surface, by dipping the fibers in a phosphate buffer. A layer of chitosan, a polycation in acidic medium, was then deposited on the nanofiber surface, thanks to electrostatic attraction. Fibers were characterized at each step of the process and the influence of the copolymer architecture on chitosan deposition was discussed. The antibacterial activity of the resulting fibers was finally assessed. [less ▲]

This paper proposes a novel approach to detect differential item functioning (DIF) among dichotomously scored items. Unlike standard DIF methods that perform an item-by-item analysis, we propose the “LR lasso DIF method”: logistic regression (LR) model is formulated for all item responses. The model contains item specific intercepts, an effect of the sum score and item-group interaction (i.e. DIF) effects, with a lasso penalty on all DIF parameters. Optimal penalty parameter selection is investigated through several known information criteria (AIC, BIC and cross-validation) as well as through a newly developed alternative. A simulation study was conducted to compare the global performance of the suggested “LR lasso DIF” method to the logistic regression and Mantel-Haenszel methods (in terms of false alarm and hit rates). It is concluded that for small samples the LR lasso DIF approach globally outperforms the logistic regression method, and also the Mantel-Haenszel method, especially in the presence of item impact, while it yields similar results with larger samples.

Herpesviruses have mainly co-evolved with their hosts for millions of years. However, bovine herpesvirus 1 (BoHV1) and related ruminant alphaherpesviruses have been reported to cross the species barrier. Bubaline herpesvirus 1 (BuHV1) is an alphaherpesvirus closely related to BoHV1 and BoHV5. According to the serological cross-relationships between ruminant alphaherpesviruses, several surveys have studied the occurrence of BoHV1-related virus infection in wild and domestic ruminant species. Recent studies in Argentina showed an increase in serological prevalence against BoHV1 related viruses in water buffaloes (Bubalus bubalis) population. The aim of this study was to investigate the presence of related ruminant alphaherpesvirus in the Argentinean water buffalo population. BuHV1 was successfully isolated from 5 out of 225 buffaloes analyzed. One isolate was obtained from nasal secretions, and the others were from vaginal swabs. The buffaloes belonged to four different farms located in northeastern Argentina. The isolates were characterized as alphaherpesvirus by direct immunofluorescence using FITC-anti-BoHV1 IgG. Restriction analysis performed with BamHI and BstEII on the complete genome showed differences between the isolates and those from BoHV1 and BoHV5 subtypes. Phylogenetic analysis on both UL27 and US6 showed similarity in tree topology. While three of the isolates grouped together with sequences of BoHV5, two other isolates clustered separately. Genetic analysis of eight concatenated sequences from all isolates and references strains showed high nucleotide sequence identity between BuHV1 and BoHV5. While three of the isolates clustered together with the BoHV5 reference strain, the last two isolates were closely related to an Australian BuHV1 strain. To our knowledge, this is the first report on the isolation and molecular characterization of BuHV1 in South America. Phylogenetic analysis suggested that two different BuHV1 lineages circulate in the Argentinean water buffalo population. [less ▲]

Fossils of Mesozoic vertebrates are rare in Scotland, particularly specimens of marine reptiles such as plesiosaurs and ichthyosaurs. We describe a suite of ichthyosaur fossils from the Early to Middle Jurassic of Skye, which to our knowledge are the first ichthyosaurs from Scotland to be described and figured in detail. These fossils span approximately 30 million years, from the Sinemurian to the Bathonian, and indicate that ichthyosaurs were a major component of Scottish marine faunas during this time. The specimens include isolated teeth that could represent the most northerly known occurrences of the widespread Sinemurian species Ichthyosaurus communis, a characteristic component of the famous Lyme Regis faunas of England, suggesting that such faunas were also present in Scotland during the Early Jurassic. An associated humerus and vertebrae from Toarcian–Bajocian-aged deposits are named as a new genus and species of basal neoichthyosaurian, Dearcmhara shawcrossi. The taxonomic affinities of this taxon, which comes from a critical but poorly sampled interval in the fossil record, suggest that non-ophthalmosaurid neoichthyosaurians dominated European assemblages around the Early–Middle Jurassic boundary, and were later replaced by ophthalmosaurids, whose radiation likely took place outside Europe. Many of these specimens were collected by amateurs and donated to museum collections, a co-operative relationship essential to the preservation of Scotland’s fossil heritage. [less ▲]

Since its creation in 1830, Belgium has experienced tensions between language and politics. The question of the linguistic or community-related nature of these tensions should be raised since they have regularly been referred to as linguistic by some researchers and as community-related by others. But the choice of these adjectives is not unimportant considering they frame the representations of the political issues at hand. The aim of this article is to tackle this question from the combined perspective of linguistics and political science. In the first, the article explores the genealogy of the adjectives ‘linguistic’ and ‘community-related’ as well as the multiplicity of their uses in the scientific literature. In the second part, it focuses on the ways citizens see and talk about Belgian federalism through the respective analyses of their mental representations and their conceptual metaphors. Such interdisciplinary endeavour, bringing together theoretical and empirical insights, seeks to yield a renewed understanding of the political relations in Belgium and to contribute to the debate about plurilingual societies.
