The aim of this study was to investigate the influence of the slaughter technique (Halal vs. Classical slaughter) on the superficial contamination of cattle carcasses, by using traditional microbiological procedures and 16S rDNA metagenetics. The purpose was also to investigate the neck area to identify bacteria originating from the digestive or the respiratory tract. Twenty bovine carcasses (10 from each group) were swabbed at the slaughterhouse, where both slaughtering methods are practiced. Two swabbing areas were chosen: one “legal” zone of 1,600 cm2 (composed of zones from rump, flank, brisket and forelimb) and locally on the neck area (200 cm2). Samples were submitted to classical microbiology for aerobic Total Viable Counts (TVC) at 30°C and Enterobacteriaceae counts, while metagenetic analysis was performed on the same samples. The classical microbiological results revealed no significant differences between both slaughtering practices; with values between 3.95 and 4.87 log CFU/100 cm2 and 0.49 and 1.94 log CFU/100 cm2, for TVC and Enterobacteriaceae respectively. Analysis of pyrosequencing data showed that differences in the bacterial population abundance between slaughtering methods were mainly observed in the “legal” swabbing zone compared to the neck area. Bacterial genera belonging to the Actinobacteria phylum were more abundant in the “legal” swabbing zone in “Halal” samples, while Brevibacterium and Corynebacterium were encountered more in “Halal” samples, in all swabbing areas. This was also the case for Firmicutes bacterial populations (families of Aerococcaceae, Planococcaceae). Except for Planococcoceae, the analysis of Operational Taxonomic Unit (OTU) abundances of bacteria from the digestive or respiratory tract revealed no differences between groups. In conclusion, the slaughtering method does not influence the superficial microbiological pattern in terms of specific microbiological markers of the digestive or respiratory tract. However, precise analysis of taxonomy at the genus level taxonomy highlights differences between swabbing areas. Although not clearly proven in this study, differences in hygiene practices used during both slaughtering protocols could explain the differences in contamination between carcasses from both slaughtering groups.

In the first part of this survey, we present classical notions arising in combinatorics on words: growth function of a language, complexity function of an infinite word, pattern avoidance, periodicity and uniform recurrence. Our presentation tries to set up a unified framework with respect to a given binary relation. In the second part, we mainly focus on abelian equivalence, $k$-abelian equivalence, combinatorial coefficients and associated relations, Parikh matrices and $M$-equivalence. In particular, some new refinements of abelian equivalence are introduced. [less ▲]

Dans l’une de ses conversations avec Joachim Gasquet sur le sens de sa peinture (et de la peinture en général), Cézanne aborde de front la conception qu’il se fait de la couleur, dans son rapport à la profondeur picturale et de son articulation à la surface : « La nature n'est pas en surface ; elle est en profondeur. Les couleurs sont l'expression, à cette surface, de cette profondeur. Elles montent des racines du monde ». Cet « organisme de couleurs » que constitue le monde est transcrit dans la peinture de Cézanne par une dynamique symbiotique de la couleur et du dessin, de la ligne et du pan. La couleur restitue, par sa masse, son surgissement, son homogénéité, presque sa viscosité, la véritable chaire perceptive du monde ; une vision qui tient à distance la perspective géométrique, photographique, cinématographique fondée sur la transparence et qui repose, comme le signale Merleau-Ponty, sur la « réversibilité des dimensions » (surface-profondeur) et l’entrelacement des choses. C’est cette épaisseur du visible rendu par la couleur que l’économie de l’image numérique nous permet de redécouvrir, moins dans le registre de la « tactilité » de l’image et la picturalité du pixel, que par l’intégration, entre le support et l’image (parfois indiscernables dans le régime optique), d’un « corps » algorithmique qui règle l’actualisation du visible. Certains défauts techniques du dispositif numérique, aujourd’hui élevés au rang de pratique artistique, permettent de révéler cette matrice qui utilise alors la couleur et la coulure comme mode de visibilité. C’est le cas du Datamoshing, technique de composition numérique qui revisite tout en la radicalisant la pratique de l’incrustation vidéo. Basée sur la perturbation volontaire d’éléments de la matrice, cette technique transforme les couleurs en une forme malléable et fluide révélant ainsi leur double nature spatiale : elles sont à la fois dans l’espace de l’image et l’espace de l’image lui-même. Ces expériences de défigurations d’images s’inscrivent dans le registre des « aberrations chromatiques » dont nous proposons ici une rapide généalogie avant d’interroger la couleur digitale dans ses spécificités.

Eleven samples of the traditional date product " Btana" prepared by direct (DBM) and indirect method (UBM) were analysed to characterize their bacterial diversity. A total of 42 representative isolates have been chosen for molecular identification. 16S rRNA gene sequencing revealed the presence of 20 species within 30.9% belonged to the genus Bacillus, 28.6% of the Staphylococcus, and Enterococcus genus. Within the minority represented species, two isolates were identified as Paenibacillus (isolated from UBM exclusively), Streptococci salivarius, Lactobacillus sakei and Klebsiella pneumoniae. Preliminary results indicate that IBM is more selective for spore former bacilli contrary to DBM that show more diversity in the bacterial flora with a prevalence of Enterococcus. API ZYM test showed that the bacilli species have a weak hydrolase activity. [less ▲]

Damage caused by ungulates to agricultural areas are difficult to evaluate because the real extent of the damage remains usually poorly described and potentially arising conflicts. Recent advances in unmanned aerial system (UAS) provide new versatile mapping and quantification possibilities in a wide range of applications. We used crop fields (Zea mays) damaged by wild boar (Sus scrofa) and compared the extent of the damage by means of three methods: i) traditional ground-based assessment ii) UAS orthoimages with operator delineation and iii) UAS Crop Height Model with automatic delineation based on height threshold. We showed for the first time that UAS could be applied for assessing damage of ungulates to agriculture. The two methods using UAS imagery provide coherent and satisfactory results and trended to underestimate the damage area when compared to in-use ground-based field expertise. However we suggest that performance of UAS should further be tested in variable conditions in order to assess the broad application of this tool. Our study describes the potential of UAS as a tool for estimating more accurately the damage area and subsequently the compensation costs for wildlife damage. The proposed approach can come in support of local and regional policies for the definitions of compensation for farmers. [less ▲]

In this article, we propose a robust statistical approach to select an appropriate error distribution, in a classical multiplicative heteroscedastic model. In a first step, unlike to the traditional approach, we don't use any GARCH-type estimation of the conditional variance. Instead, we propose to use a recently developed nonparametric procedure (Mercurio and Spokoiny, 2004): the Local Adaptive Volatility Estimation (LAVE). The motivation for using this method is to avoid a possible model misspecification for the conditional variance. In a second step, we suggest a set of estimation and model selection procedures (Berk-Jones tests, kernel density-based selection, censored likelihood score, coverage probability) based on the so-obtained residuals. These methods enable to assess the global fit of a set of distributions as well as to focus on their behavior in the tails, giving us the capacity to map the strengths and weaknesses of the candidate distributions. A bootstrap procedure is provided to compute the rejection regions in this semiparametric context. Finally, we illustrate our methodology throughout a small simulation study and an application on three time series of daily returns (UBS stock returns, BOVESPA returns and EUR/USD exchange rates) [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 ▲]

Outlier detection techniques in spatial data should allow to identify two types of outliers: global and local ones. Local outliers typically have non-spatial attributes that strongly differ from those observed on their neighbors. Detecting local outliers requires to be able to work locally, on neighborhoods, in order to take into account the spatial dependence between the statistical units under consideration, even though the outlyingness is usually measured on the non-spatial variables. Many procedures have been outlined in the literature, but their number reduces when one wants to deal with multivariate non-spatial attributes. In this paper, focus is on the multivariate context. A review of existing procedures is done. A new approach, based on a two-step improvement of an existing one, is also designed and compared with the benchmarked methods by means of examples and simulations. [less ▲]

En croisant plusieurs textes sur le montage et la juxtaposition d’images hétérogènes de l’essayiste et théoricien des médias allemand Hans Magnus Enzensberger, cet article met à jour un lien d’ordre esthétique entre divers dispositifs médiatiques passés et contemporains. L’identification de ce lien permet d’affranchir la critique théorique du paradigme évolutionniste de l’échec et du progrès (technologique et politique), pour l’ouvrir à un ensemble d’éclairages réciproques et non linéaires. Dans ce cadre, l’usage des textes d’Enzensberger dépasse, lui aussi, toute forme de périodisation.

The famous Doignon-Bell-Scarf theorem is a Helly-type result about the existence of integer solutions to systems of linear inequalities. The purpose of this paper is to present the following quantitative generalization: Given an integer k, we prove that there exists a constant c(n,k), depending only on the dimension n and on the number k, such that if a bounded polyhedron {x in R^n : Ax <= b} contains exactly k integer points, then there exists a subset of the rows, of cardinality no more than c(n,k), defining a polyhedron that contains exactly the same k integer points. In this case c(n,0)=2^n as in the original case of Doignon-Bell-Scarf for infeasible systems of inequalities. We work on both upper and lower bounds for the constant c(n,k) and discuss some consequences, including a Clarkson-style algorithm to find the l-th best solution of an integer program with respect to the ordering induced by the objective function.

Neuroimaging studies have revealed the recruitment of a range of neural networks during the resting state, which might reflect a variety of cognitive experiences and processes occurring in an individual's mind. In this study, we focused on the default mode network (DMN) and attentional networks and investigated their association with distinct mental states when participants are not performing an explicit task. To investigate the range of possible cognitive experiences more directly, this study proposes a novel method of resting-state fMRI experience sampling, informed by a phenomenological investigation of the fluctuation of mental states during the resting state. We hypothesized that DMN activity would increase as a function of internal mentation and that the activity of dorsal and ventral networks would indicate states of top–down versus bottom–up attention at rest. Results showed that dorsal attention network activity fluctuated as a function of subjective reports of attentional control, providing evidence that activity of this network reflects the perceived recruitment of controlled attentional processes during spontaneous cognition. Activity of the DMN increased when participants reported to be in a subjective state of internal mentation, but not when they reported to be in a state of perception. This study provides direct evidence for a link between fluctuations of resting-state neural activity and fluctuations in specific cognitive processes. [less ▲]

Incident reporting systems (IRSs) are used in many organisations as tools that promote safety by allowing to collectively learn from incidents. In this paper, we propose a social constructivist approach to learning from incidents, in which the focus is not purely on safety, but on the technology of incident reporting itself. We employ Wiebe Bijker’s work on the Social Construction of Technology to open up the analysis of a specific IRS in use at the Belgian Nuclear Research Center. For this purpose, we carried out 28 interviews with key local actors and collected documents and observation notes. Such social constructivist perspective provides detailed insight into the practices of reporting and the meanings of learning from incidents. Our research shows that various actors within the organisation frame the IRS differently. These framings each have their own implications for the vulnerability of the organisation. [less ▲]

In this letter, we show how a simple motion-guided nonlinear filter can drastically improve the accuracy of several pedestrian detectors. More specifically, we address the problem of how to pre-filter an image so almost any pedestrian detector will see its false detection rate decrease. First, we roughly identify moving pixels by cumulating their temporal gradient into a motion history image (MHI). The MHI is then used in conjunction with a nonlinear filter to filter out background details while leaving untouched foreground moving objects. We also show how a feedback loop as well as a merging procedure between the filtered and the unfiltered frames can further improve results. We tested our method on 26 videos from 6 categories. The results show that for a given miss rate, filtering out background details reduces the false detection rate by a factor of up to 69.6 times. Our method is simple, computationally light, and can be implemented with any pedestrian detector. Code is made publicly available at: https://bitbucket.org/wany1601/pedestriandetection. [less ▲]

Freeplay is a significant source of nonlinearity in aeroelastic systems and is strictly regulated by airworthiness authorities. It splits the phase plane of such systems into three piecewise linear subdomains. Depending on the location of the freeplay, limit cycle oscillations can result that span either two or three of these subdomains. The purpose of this work is to demonstrate the existence of two-domain cycles both theoretically and experimentally. A simple aeroelastic system with pitch, plunge and control deflection degrees of freedom is investigated in the presence of freeplay in pitch. It is shown that two-domain and three-domain cycles can result from a grazing bifurcation and propagate in the decreasing airspeed direction. Close to the bifurcation, the two limit cycle branches interact with each other and aperiodic oscillations ensue. Equivalent linearization is used to derive the conditions of existence of each type of limit cycle and to predict their amplitudes and frequencies. Comparisons with measurements from wind tunnel experiments demonstrate that the theory describes these phenomena with accuracy. [less ▲]

The current drive for increased efficiency in aeronautic structures such as aircraft, wind turbine blades and helicopter blades often leads to weight reduction. A con- sequence of this tendency can be increased flexibility, which in turn can lead to un- favourable aeroelastic phenomena involving large amplitude oscillations and non- linear effects such as geometric hardening and stall flutter. Vibration mitigation is one of the approaches currently under study for avoiding these phenomena. In the present work, passive vibration mitigation is applied to a nonlinear experimental aeroelastic system by means of a linear tuned vibration absorber. The aeroelastic apparatus is a pitch and flap wing that features a continuously hardening restoring torque in pitch and a linear restoring torque in flap. Extensive analysis of the sys- tem with and without absorber at pre-critical and post-critical airspeeds showed an improvement in flutter speed of around 36%, a suppression of a jump due to stall flutter, and a reduction in LCO amplitude. Mathematical modelling of the exper- imental system is used to demonstrate that optimal flutter delay is achieved when two of the system modes flutter at the same flight condition. Nevertheless, even this optimal absorber quickly loses effectiveness as it is detuned. The wind tunnel mea- surements showed that the tested absorbers were much slower to lose effectiveness than those of the mathematical predictions. [less ▲]

It is established that the WLE always returns finite ability estimates. This general result is valid for dichotomous (one-, two-, three- and four-parameter logistic) IRT models, the class of polytomous difference models and divide-by-total models, independently of the number of items, the item parameters and the response patterns. Further implications of this result are outlined. [less ▲]

This paper describes the development of a complete methodology for the aeroservoelastic modeling of horizontal axis wind turbines at the conceptual design stage. The methodology is based on the implementation of unsteady aerodynamic modeling, advanced description of the control system and nonlinear finite element calculations in the SWT wind turbine design package. The aerodynamic modeling is carried out by means of fast techniques, such as the Blade Element Method and the unsteady Vortex Lattice Method, including a free wake model. The complete model also includes a description of a doubly fed induction generator and its control system for variable speed operation. The SWT software features a non-linear finite element solver with multi-body dynamics capability. The full methodology is used to perform complete aeroservoelastic simulations of a realistic 2MW wind turbine model. The interaction between the three components of the approach is carefully analyzed and presented here. [less ▲]

Introduction: The Attitudes to Aging Questionnaire (AAQ) was developed to measure attitudes toward the aging process as a personal experience from the perspective of older people. The present study aimed to validate the French version of the AAQ. Participants and methods: This study examined factor structure, acceptability, reliability and validity of the AAQ’s French version in 238 Belgian adults aged 60 years or older. In addition, participants provided information on demographics, self-perception of their mental and physical health (single items), quality of life (WHOQOL-OLD) and social desirability (DS-36). Results: Exploratory Factor Analysis produced a three-factor solution accounting for 36.9% of the variance. No floor or ceiling effects were found. The internal consistency, measured by Cronbach’s alpha coefficients for the AAQ subscales were 0.62 (Physical Change), 0.74 (Psychological Growth), and 0.75 (Psychosocial Loss). A priori expected associations were found between AAQ subscales, self-reported health and quality of life, indicating good convergent validity. The scale also showed a good ability to discriminate between people with lower and higher education levels, supporting adequate known-groups validity. Finally, we confirmed the need to control for social desirability biases when assessing self-reported attitudes toward one’s own aging. Conclusion: The data support the usefulness of the French version of the AAQ for the assessment of attitudes toward their own aging in older people. [less ▲]

Polymers with repeating phosphoester linkages in the backbone are biodegradable materials that emerge as a promising class of novel biomaterials, especially in the field of drug delivery systems. In contrast to aliphatic polyesters, the pentavalency of the phosphorus atom offers a large diversity of structures and as a consequence a wide range of properties for these mate- rials. In this paper, it is focused on the synthesis of well-defined polyphosphoesters (PPEs) by organocatalyzed ring-opening polymerization, improving the functionalities by combination with click reactions, degrada- tion of functional PPEs and their cytotoxicity, and inputs for applications in drug delivery.

Fundamentals of vernacular architecture have been used in bioclimatic architecture which has gradually become the inspiration of various movements in contemporary architecture. The study points out that the development of bioclimatism in architecture has followed the pattern of a natural evolutionary process in which “natural selection” is likely motivated by several factors, including resources and environment problems, and driven by different mechanisms including novel building design concepts and methods, new standards and codes, discoveries in building science and construction costs. This study is an effort aimed to clarify the evolution process of the bioclimatic approach in architecture over time and its influences on contemporary movements in architecture. The paper shows also that the evolutionary theory generated new scientific tools able to improve building design thanks to simulation-based optimization methods applied to building performances. Finally, this study investigates new motivations in the era of climate change whose effects are expected to introduce more challenges as well as more trends towards a sustainable built environment through the new concept of Eco-adaptive architecture.

The strength of respiratory muscles is crucial for quality of life, especially for patients with lung or neurological disorders. Several methods can be used to assess them: i.e direct or indirect, voluntary or involuntary. The conventional spirometry method assesses indirectly the respiratory function by measuring maximum inspiratory and expiratory pressure, which reflects the coordination of all respiratory muscles. Techniques of magnetic and electrical stimulation can detect a specific muscle dysfunction, independently of the patient's motivation, however they are invasive methods as measurements are made in the esophagus and stomach. The voluntary techniques are generally non-invasive and require patient's cooperation. Measures of respiratory muscle strength, coupled to a conventional spirometry, can predict the development of ventilatory support in patients at risk, and may be useful during weaning from mechanical ventilation in intensive care units.

Les ouvrages de Frédéric Lordon ont offert ces dernières années un éclairage nouveau des mécanismes de la finance et du capitalisme en régime néolibéral, en vertu de la place centrale qu’ils accordent aux affects. Il est frappant que cette entreprise – qui est triple: analyse de la finance, analyse du capitalisme, analyse de la domination – soit doublée d’une attention portée au discours même qui la développe. On peut repérer une telle attention dans la pluralité des genres de discours qu’investit Frédéric Lordon : ouvrages « savants » ou « universitaires », mais aussi courts essais engagés aux éditions Raisons d’agir, articles de presse dans Le Monde Diplomatique notamment, tenue du blog « La pompe à phynance » sur le site du même journal, et même pièce de théâtre récemment adaptée au cinéma, D’un retournement l’autre. Comédie sérieuse sur la crise financière. En quatre actes, et en alexandrins . Diversité de genre entre les différents types de textes, donc. Diversité interne à chacun de ces textes, aussi : le lecteur de Frédéric Lordon se trouve toujours à cheval sur plusieurs codes rhétoriques dont joue l’auteur dans un même ouvrage. On pourrait bien sûr tenir cette double diversité pour la simple conséquence du talent d’écriture de Lordon, ou d’un plaisir pris par l’auteur à jouer du langage et des ethos qu’il construit. Le présent article propose au contraire de considérer cette diversité comme le résultat d’un véritable travail sur les modalités rhétoriques du discours critique sur le capitalisme financiarisé, qu’il faut articuler aux principaux postulats de sa théorie sociale. L’hypothèse défendue sera, précisément, de considérer qu’il y a une construction rhétorique qui participe de l’entreprise critique et, du même coup, qui s’inscrit comme un geste politique dans une « société des affects ».

Le photogramme est, au cinéma, la plus petite unité de prise de vue. Image fixe, unité élémentaire du film, le photogramme forme la cellule figée d’un mouvement qui se reconstitue sous l’effet d’un défilement réglé (24 photogrammes/seconde) par le dispositif technique du cinéma. 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. Nous allons donc envisager certaines pratiques ou certains usages du photogramme cinématographique, tout en essayant de dégager, au départ de ces pratiques, les éléments d’une théorie du photogramme, que Roland Barthes et Sylvie Pierre appelaient déjà de leurs vœux.

Production and purification of hydrophobin HFBII has recently been the subject of intensive research, but the yield of production needs to be further improved for a generic use of this molecule at industrial scale. In a first step, the influence of different carbon sources on the growth of Trichoderma reesei and the production of HFBII was investigated. The optimum productivity was obtained by using 40 g/L lactose. Carbon starvation and excretion of extracellular enzyme were determined as two main conditions for the production of HFBII. In the second phase, and according to the physiological mechanisms observed during the screening phase, a bioreactor set up has been designed and two modes of cultures have been investigated, i.e. the classical submerged fermentation and a fungal biofilm reactor. In this last set-up, the broth is continuously recirculated on a metal packing exhibiting a high specific surface. In this case, the fungal biomass was mainly attached to the metal packing, leading to a simplification of downstream processing scheme. More importantly, the HFBII concentration increased up to 48.6 ± 6.2 mg/L which was 1.8 times higher in this reactor configuration and faster than the submerged culture. X-ray tomography analysis shows that the biofilm overgrowth occurs when successive cultures are performed on the same packing. However, this phenomenon has no significant influence on the yield of HFBII, suggesting that this process could be operated in continuous mode. Protein hydrolysis during stationary phase was observed by MALDI-TOF analysis according to the removal of the last amino acid from the structure of HFBII after 48 h from the beginning of fermentation in biofilm reactor. Hopefully this modification does not lead to alternation of the main physicochemical properties of HFBII. [less ▲]

The progress accomplished during the past decade in nonlinear system identi fication in structural dynamics is considerable. The objective of the present paper is to consolidate this progress by challenging the community through a new benchmark structure exhibiting complex nonlinear dynamics. The proposed structure consists of two o ffset cantilevered beams connected by a highly flexible element. For increasing forcing amplitudes, the system sequentially features linear behaviour, localised nonlinearity associated with the buckling of the connecting element, and distributed nonlinearity resulting from large elastic deformations across the structure. A finite element-based code with time integration capabilities is made available at http://sem.org/TDIV-Nonlin.asp. This code permits the numerical simulation of the benchmark dynamics in response to arbitrary excitation signals. [less ▲]

Ikaite precipitation within sea ice could act as a significant sink for atmospheric CO2. However, the fate of these ikaite crystals is still poorly understood. We quantify temporal inorganic carbon dynamics from initial sea ice formation from open water to its melt during a month-long experiment in a sea ice-seawater mesocosm pool. Within sea ice, ikaite precipitation and CO2 exchange with the atmosphere were the main processes affecting inorganic carbon dynamics, while the dissolution of ikaite was the main process affecting inorganic carbon dynamics in the underlying seawater. Based on the total alkalinity (TA) and total dissolved inorganic carbon (TCO2) within sea ice and seawater, we estimated ikaite precipitated up to 167 ± 3 µmol kg-1 within sea ice; up to 57 % of the ikaite precipitated within sea ice was exported to the underlying seawater where it was dissolved. Ikaite export from the ice to the underlying seawater was associated with brine rejection during sea ice growth, increased sea ice vertical connectivity due to the upward percolation of seawater, and meltwater flushing during sea ice melt. The dissolution of the ikaite crystals in the water column kept the seawater pCO2 undersaturated compared to the atmosphere in spite of increased salinity, TA, and TCO2 associated with sea ice growth. Results indicate that ikaite export from sea ice and its dissolution in the underlying seawater can potentially hamper the effect of oceanic acidification on the aragonite saturation state (Ωaragonite) in fall and winter in ice-covered areas, at the time when Ωaragonite is smallest.

Parmi les journaux comiques les plus en vue du XIXe siècle, l’hebdomadaire Tintamarre occupe une place de choix.

Cet article interroge les implications et les effets de cette double casquette fantaisiste en ce qui concerne la logique interne du journal et le développement en son sein d’une poétique parodique spécifique, mais également en matière d’institutionnalisation d’une forme de mystification littéraire.

The right dorsal premotor cortex (PMd) of humans has been reported to be involved in a broad range of motor and cognitive functions. We explored the basis of this behavioral heterogeneity by performing a connectivity-based parcellation using meta-analytic approach applied to PMd coactivations. We compared our CBP results to parcellations obtained through resting-state functional connectivity and probabilistic diffusion tractography,. Functional connectivity profiles and behavioral decoding of the resulting PMd subregions allowed characterizing their respective behavior profile. These procedures divided the right PMd into five distinct subregions that formed a cognitive-motor gradient along a rostro-caudal axis. In particular, we found (i) a rostral subregion functionally connected with prefrontal cortex, which likely supports high-level cognitive processes, such as working memory (ii) a central subregion showing a mixed behavioral profile and functional connectivity to parietal regions of the dorsal attention network, and (iii) a caudal subregion closely integrated with the motor system. Additionally, we found (iv) a dorsal subregion, preferentially related to hand movements and connected to both cognitive and motor regions, and (v) a ventral subregion, whose functional profile fits the concept of an eye-movement related field. In conclusion, right PMd may be considered as a functional mosaic formed by five subregions. [less ▲]

Les Associations des Enfants et Jeunes Travailleurs du Burkina Faso (AEJT/BF) sont une représentation nationale du Mouvement Africain des Enfants et Jeunes Travailleurs (MAEJT), créé à la fin des années 1980. Le mouvement est fondé sur deux grands principes : les douze droits prioritaires des enfants et jeunes travailleurs et le principe du « protagonisme » (l’enfant travailleur comme acteur capable) . Ce chapitre présente et analyse le fonctionnement de ce mouvement au Burkina Faso, les changements qu’il a contribué à apporter à la question sociale du travail des enfants et les résultats de la mise en application des principes annoncés. S’appuyant sur une enquête ethnographique menée en son sein, le texte offre des données inédites sur les réalités d’un acteur collectif qui, en utilisant à son avantage la rhétorique de la « participation » des enfants (art.12, Convention des droits de l’enfant), a réussi à s’insérer dans l’arène nationale de la protection de l’enfance. Toutefois, la question de la place et du rôle des enfants ainsi que celle du “vieillissement” des membres sont quelques-uns des défis auxquels la section burkinabè du mouvement doit faire face.

L’accompagnement collectif constitue un mode de développement des individus et des équipes qui bénéficie aujourd’hui d’une abondante littérature méthodologique et théorique.

Basé sur quatre études de cas, cet article propose une modélisation des différentes possibilités d’évaluations, triées en fonction de quatre critères (niveaux, temporalités, contenus, formes). Chaque modalité est illustrée à l’aide d’un cas fil rouge. Cela débouche sur une multiplicité de possibilités d’application de l’évaluation au service de l’accompagnement.

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 ▲]

Resting-state functional connectivity analysis has become a widely used method for the investigation of human brain connectivity and pathology. The measurement of neuronal activity by functional MRI, however, is impeded by various nuisance signals that reduce the stability of functional connectivity. Several methods exist to address this predicament, but little consensus has yet been reached on the most appropriate approach. Given the crucial importance of reliability for the development of clinical applications, we here investigated the effect of various confound removal approaches on the test–retest reliability of functional connectivity estimates in two previously defined functional brain networks. Our results showed that gray matter masking improved the reliability of connectivity estimates, whereas denoising based on principal components analysis reduced it. We additionally observed that refraining from using any correction for global signals provided the best test–retest reliability, but failed to reproduce anti-correlations between what have been previously described as antagonistic networks. This suggests that improved reliability can come at the expense of potentially poorer biological validity. Consistent with this, we observed that reliability was proportional to the retained variance, which presumably included structured noise, such as reliable nuisance signals (for instance, noise induced by cardiac processes). We conclude that compromises are necessary between maximizing test–retest reliability and removing variance that may be attributable to non-neuronal sources. [less ▲]

Current evidence continues to support the potential for bone turnover markers (BTM) to provide clinically useful information particularly for monitoring the efficacy of osteoporosis treatment. Many of the limitations identified earlier remain, principally in regard to the relationship between BTM and incident fractures. Important data are now available on reference interval values for CTX and PINP across a range of geographic regions and for individual clinical assays. An apparent lack of comparability between current clinical assays for CTX has become evident indicating the possible limitations of combining such data for meta-analyses. Harmonization of units for reporting serum/plasma CTX (ng/L) and PINP (mug/L) is recommended. The development of international collaborations continues with an important initiative to combine BTM results from clinical trials in osteoporosis in a meta-analysis and an assay harmonization program are likely to be beneficial. It is possible that knowledge derived from clinical studies can further enhance fracture risk estimation tools with inclusion of BTM together with other independent risk factors. Further data of the relationships between the clinical assays for CTX and PINP as well as physiological and pre-analytical factors contributing to variability in BTM concentrations are required.

Novel chocolate spreads were enriched by soluble and insoluble dietary fibers from Tunisian Deglet Nour date seeds at 1, 2, 3, 4 and 5% levels in the conventional chocolate spread. Defatted Deglet Nour date seeds (DNDS), date seed soluble fiber concentrate (DSSFC) and date seed insoluble fiber concentrate (DSIFC) were characterized by high levels of dietary fibers (80 – 90%). Chocolate spread enriched with 5% of DSSFC presented the highest OBC (304.62%) compared to the control (102%). Whatever the DSIFC and DSSFC incorporation levels, no significant difference was recorded between the firmness, chewiness and adhesiveness of prepared chocolate spreads compared to the control (P<0.05). Sensory evaluation revealed that all prepared chocolate spreads enriched by DSIFC and DSSFC were accepted by panelists. These results indicated the value of date seeds as new source of dietary fibers to develop chocolate spread and could also improve health benefits and functional properties. [less ▲]
