    A Decision Support System to Evaluate Suppliers in the Context of Global Service Providers

    In this paper, we present a decision support system (DSS) developed for a global service provider (GSP), which solves a real-world supplier selection problem. The GSP operates in the Italian market of facility management, supplying customers with a variety of services. These services are subcontracted to external qualified suppliers spread all over Italy and chosen on the basis of several criteria, such as service quality, availability and proximity. Selecting the best supplier is a complex task due to the large number of suppliers and the great variety of facility management services offered by the GSP. In the proposed DSS, the choice of the best supplier for a certain service is made according to a thorough multi-criteria analysis. The weights for the criteria were generated by implementing both a simplified analytic hierarchy process and a revised Simos' procedure, later validated by the decision makers at the GSP. The DSS provides quick access to historical performance data, visual tools to aid decisions, and a suggested ranked list of suppliers for each given contract. The effectiveness of the proposed system was assessed by means of extensive simulations on a seven-year period of real-data and several rounds of validation with the company

    Micro-collinearity between switchgrass BAC clones and orthologous regions from <i>Brachypodium</i> (<i>Bd</i>), rice (<i>Os</i>), sorghum (<i>Sb</i>) and maize (<i>Zm</i>).

    <p>Colored boxes along the physical location in the genome of each species represent genes and arrows in the colored boxes indicate the transcriptional orientation of each gene. Orthologous genes are given the same color and are connected by dotted lines. Grey bars represent genes from respective genomes lacking syntenic match in switchgrass. Dashed lines represent breaks in contiguity to allow larger genomic regions of the chromosomes to fit in the scale of the figures and the genes from these regions lacking syntenic match have not been plotted. The scale is shown at the bottom of each section. NCBI accession numbers for switchgrass BAC clones are given at top left of each section. Detailed information on accession numbers and gene names is given in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0033892#pone.0033892.s008" target="_blank">File S7</a>.</p

    <p>Switchgrass BAC libraries (Pv_ABa and Pv_ABb) were screened by high-density filter hybridizations to estimate chloroplast- or mitochondrial-specific DNA and representation of single/low copy genes. Representative filter hybridization data used to estimate chloroplast (A, D) and mitochondrial (B, E) contaminants, and the library coverage based on the presence of a single copy gene, <i>brittle culm 10</i> (C, F). Black arrows in C and F identify the signal from <i>BC10</i> probes.</p

    Fashion: from Attitudes to Poses

    Borrowing some of Aby Warburg’s methods from his Mnemosyne Atlas, this paper experiments with an anti-linear, non-teleological method of writing fashion history. It investigates fashion movement, gesture and pose, and their afterlife in images and objects. It thus looks at the intersection of time and the gesture, particularly in relation to the idea of the ‘now’, a central organising principle of fashion. To this end, it juxtaposes images of the body in motion from sources as varied as scientific photography, etiquette manuals and fashion magazines. Spanning three centuries, though not chronologically, the images show a range of activities: not only fashion posing, but also tennis-playing, duelling, dancing, military marching, social gestures, and going to the races. The paper proposes that each image is charged with some quality or attribute that is also immanent in one or more of the others, even though they have no causal or temporal relationship
