Data supporting: Are high-throughput root-phenotyping platforms suitable for informing root-system architecture models with genotype-specific parameters? An evaluation based on the root model ArchiSimple and a small panel of wheat cultivars
No full text<p><span>The dataset comprises estimates of six major parameters of the root system architecture model ArchiSimple for 14 bread wheat cultivars grown in several experiment experiments carried out two high-throughput root phenotyping platforms (4MPI at INRAE, UMR AgroEcologie and RootPheAir at UCL) with different growth media and non-destructive imaging systems together with a conventional set-up in the green house in the Montpellier Plant Phenotyping Platforms (M3P, INRAE, UMR LEPSE) with a solid growth medium. Data for the two to three replicate plants in each experiments are reported. The dataset also include daily weather data in each experiment. A detailed description of the plant growth conditions and Methods can be found in theassociated publication.</span></p>
Replication Data for: Global needs for nitrogen fertilizer to improve wheat yield under climate change
No full textThe dataset reported here was created to analyze the value of physiological traits identified by the International Wheat Yield Partnership (IWYP) to improve wheat potential in high-yielding environments and asses the amount of N fertilizer that would be needed to achieve yield potential. Th dataset consists of wheat grain yield and other key crop and soil variables simulated with 12 wheat crop growth models at 34 high-rainfall or irrigated locations from key wheat growing regions in the world. Simulations are for the 1981-2010 baseline period and two mi-century (2040-2069) future climate scenarios (RCP4.5 and RCP8.5). Daily weather data for each of the 34 global locations for the baseline period (1980-2010) were obtained from the AgMERRA climate dataset. Climate projections were taken from five global climate models (GCMs; HadGEM2-ES, MIROC5, MPI-ESM-MR, GFDL-CM3, and GISS-E2-R) drawn from the Fifth Coupled Model Intercomparison Project (CMIP5). Other data include soil characteristics and initial soil conditions, and cultivar information for all locations. For each location, local mean sowing, anthesis and maturity dates were supplied with qualitative information on vernalization requirements and photoperiod sensitivity. Simulations were performed with unlimited soil nitrogen availability and with N fertilizer application rates ranging from 0 to 400 kg N ha-1 in steps of 50 kg N ha-1. Simulations include end-of-season results for 24 crop and soil variables simulated by the 12 wheat crop models. Simulation protocols used by the individual modeling teams are included, with all necessary information to execute them with a crop growth model
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
