Le but ultime de la présente recherche est de modéliser la performance des maisons de luxe de manière transversale (nous décidons de ne pas privilégier l’approche marketing comme une grande partie de la littérature dédiée à la gestion des métiers du luxe) et atemporelle. Nous proposons d’organiser, au travers du Prime de la Performance (Neely, Adams et Kennerley, 2002), les FCS dont la mise en œuvre permet d’atteindre la performance globale. Cette recherche constitue donc un premier pas vers une modélisation de la performance de la maison de luxe. [less ▲]

Current practice in industry is to rely on linear finite element simulations. However, nonlinearity is a frequent occurrence in engineering structures. It is at the origin of rich and complex dynamical phenomena that cannot be observed in linear structures. Solving both the direct and inverse problems in nonlinear structural dynamics therefore warrants the development of appropriate methodologies. The focus of the presentation will first be on the inverse problem. We will describe the different steps of the nonlinear system identification process and discuss the current capabilities of existing methods. The presentation will then address the direct problem during which the identified model is used for accurately predicting the structure’s dynamic characteristics. A rigorous nonlinear extension of modal analysis will be presented, and we will show that it represents a very useful framework for understanding nonlinear dynamical phenomena and supporting design decisions. Two real-life aerospace structures will be considered for illustrating the proposed developments. [less ▲]

In a context of high productivity, eggs’ quality assessment is necessary for enhanced safety and quality assurance towards the consumers and feedback for producers. The quality assessment of eggs and egg products is performed using destructive and time-consuming methods, therefore the use of rapid tools becomes mandatory, especially in the case of a high production rate. Near Infrared (NIR) spectroscopy is considered a very reliable and rapid technique with large use in food industry. At the farm level, NIR spectroscopy technique would be an interesting tool to determine the chemical and physical properties of eggs, eggshell and internal quality and, moreover, this information may help the layer farm manager when a problem occurs in the flock. Its application in the egg industry is aimed at the quality changes in eggs during storage and quality assessment of the egg products, through the compositional analysis. It is possible and in some cases successful the prediction and/or determination of different parameters such as: protein, total lipid and total solids content (for liquid egg products), polyunsaturated fatty acids (for freeze-dried egg yolk), moisture, fat and protein content (for spray-dried whole eggs). In addition, for the white colored shell eggs, the detection of blood and meat spots is also successful. Further studies with NIR and near infrared hyper spectral imaging system (NIR-HSI) are needed in this direction, as the results obtained until now are very promising for the development of a rapid tool for quality assessment of eggs and egg products.

The aim of this analysis was to determine whether pregnancy loss (PL) after embryo transfer (ET) in cattle was related to maternal progesterone (P4) concentrations during and shortly after ET, and maternal bovine pregnancy-associated glycoprotein-1 (bPAG-1) concentrations in plasma at days 25–35 of gestation. Embryos (n = 260) were produced either in vivo after superovulation (n = 115), or in vitro from oocytes (obtained with ovum pick-up) in co-culture (n = 44) or cultured in a synthetic medium (n = 101). Overall, PL was 56.9% (148) and no significant differences occurred in calving rate among the three embryo production groups. There was no difference in P4 concentrations on days 7–14 of gestation in the three groups, nor between ongoing and interrupted pregnancies. Between days 25 and 35 of pregnancy, bPAG-1 concentrations were unaffected by embryo production, but in cattle that had PL between days 26 and 120, four bPAG-1 profiles could be detected. Between days 25 and 32, bPAG-1 concentrations were influenced by PL, and concentrations were significantly lower in animals in which PL occurred between days 26 and 120 than in those animals that aborted later or calved at term. Early P4 concentrations suggested that maternal luteal factors were not responsible for PL which appeared to be caused by impaired conceptus development (regardless of embryo type) as reflected by low maternal bPAG-1 concentrations prior to embryonic death [less ▲]

Background Studies in population genetics are mainly based on the analysis of genetic variations among different populations. With the advent of advanced genotyping technology, large number of Single Nucleotide Polymorphisms (SNPs) can be used to capture the underlying population variations. Iterative pruning principal component analysis (ipPCA) is a very powerful tool to cluster subpopulations based on their SNP profiles. However, when several similar populations are considered in the analysis, differentiating these populations can become very challenging. Haplotype has been known to capture more segregation information and higher power than SNP but due to high inference complexity, this concept has not been widely used. Recently, haplotype sharing (HS) was reported as a good alternative method to evaluate variation among populations. HS interrogates the entire genotyping without estimating haplotype block, making it computational efficient, yet retaining population profile. Adopting HS technique and introducing a new haplotype encoding as the input to ipPCA to perform population clustering can yield very good outcomes. Results In this study we transformed an indigenous Thai SNP genotyping data, obtained from Pan Asian SNP consortium, into encoded haplotype profiles. The dataset include 13 indigenous populations (245 individuals) composing of approximately 54K SNPs for each individual. To do this, an encoded haplotype matrix was constructed by inferring overlapping haplotype based on sliding window approach in BEAGLE, an efficient haplotype inference tool. We fed this encoded haplotype matrix to ipPCA to cluster these individuals into sub-groups using only their genetic profiles. We compared the results obtained from standard protocol of ipPCA with the one that use the encoded haplotype matrix in terms of numbers of clustered subpopulations as well as the accuracy to correctly assign an individual to a correct subpopulation. Using the encoded haplotype matrix as input to ipPCA rendered the exact 13 subpopulations to be clustered with 99.18% of individual assignment accuracy, whereas the conventional ipPCA identified only 10 subpopulations with 93.47% of individual assignment accuracy. Conclusions Our result demonstrated the great potential of using the encoded haplotype matrix with ipPCA for population genetics studies. This new protocol can promote the clustering of individuals using only their genetic profiles. [less ▲]

The 21st century is rich in mutations regarding veterinary medicine; society has never been so far from farm animal practices in industrialized countries, and so demanding in developing nations for a continuous milk and meat production. Meanwhile, even this great distance in northern nations between agriculture and society, our work has never been so much analyzed for its potential risk on human health and production quality. As health is now globalized, following trade and science, exchange could be the source of several pathological emergences. Focusing on animal health, our responsibility toward “larga manu” use of antibiotics has been identified and criticized. This situation is also happening in a time where, nevertheless our industrialization of agricultural production, ancillary exams are still expensive, and most of the time non valuable regarding a common cattle practice time schedule. So yes, we are mainly still experiencing empirical use of antibiotics like our pairs did, back several decades before. Yet, there exists nowadays many tools to analyze whether our practice could be considered as harmful to humanity survival and good use of priority antibiotics. We therefore have to reconsider our practice of Antibiotherapy, regarding these new challenges and find new ways for medical management of infectious diseases. [less ▲]

In the wake of Richards Benton’s “Keats and Zen” (published in Philosophy East and West (1966)), this paper sets out to examine Janet Frame’s appropriation of Buddhist philosophy in Snowman, Snowman (1962). The novella’s allusions to a Buddhist-like epistemology, together with its subtle references to Scandinavian myths, however, have so far remained uncovered and are therefore best approached in the light of what has been called “the suppressed intertextuality in post-colonial writing”. The author’s intention in this paper is twofold: On the one hand, the author will suggest that post-colonial writers do not necessarily write against the Western canon and that maintaining the contrary amounts to vindicating the centrality of imperial texts in the contemporary literary scene—an endeavour which is hardly post-colonial. On the other hand, the author will go some way towards shifting eastward the core of Frame’s ontology by suggesting that her poetics is anchored not only in Western thinking, but also, perhaps more importantly so, in Eastern philosophy. The author’s primary impulse, however, in examining the interplay between canonical and peripheral intertextualities, is to illuminate in fundamental fashion the haunting beauty of the writer’s universe and the lyricism of Snowman, Snowman.

In Europe, farmers have to manage larger herds but, at the same time, want to have a normal social life. So, the automatic milking system (AMS) can bring solutions. This technology implies in most cases, the cessation of grazing although grazing is appreciated by the consumers who consider it to be a natural practice. At the experimental farm of the University of Liege, the concept of a mobile milking robot has been developed with a private company. The prototype is used indoors during the winter season and is moved outdoors during the grazing season in pastures romote from the farm. [less ▲]

Background: General practitioners (GPs) and occupational physicians (OPs) play an important role in detecting and managing substance abuse in the working population. Their collaboration is critical in coordinating care, facilitate a quicker rehabilitation and shorten sickleave. A systematic literature search was performed according to the ADAPTE-framework to explore if guidelines exist for collaboration between GPs and OPs in substance abuse management. Method: International guidelines regarding collaborative care for alcohol abuse, illicit drug use and hypnotics and tranquilizers were identified by a detailed systematic search in the Guidelines International Network (GIN) and US National Guidelines Clearinghouse (NGC) databases. Results: In total 20 guidelines were considered of sufficient methodological quality, based on criteria of the Appraisal of Guidelines for Research and Education (AGREE) II instrument. Two out of 20 eligible guidelines reported on the role of OPs. There is a lack of adequate evidence on the role of the OP in substance abuse management. No practical avenues for collaboration between GPs and OPs in the management of substance abuse were suggested. Conclusions: In order to ensure adequate substance abuse management, collaborative models for general practice and occupational health should be developed. We recommend to study pros and cons for collaboration as well as the best way to achieve it. [less ▲]
