Valorisation des prairies IE ASTER
No full textCe jeu de données détaille les modes de valorisation des prairies temporaires et permanentes de l’installation expérimentale INRAE ASTER. Les données sont géolocalisées sur les parcelles de l’installation expérimentale. Les données concernent la nature de l’occupation du sol (prairies permanentes ou temporaires, cultures) et détaillent les récoltes de fourrages (date de fauche et d’enlèvement des fourrages, rendements observés) et les périodes de pâturage. La biomasse pâturée par les animaux est estimée selon (i) la localisation des animaux, (ii) la composition des lots d’animaux et (iii) la consommation individuelle
Modélisation matricielle de la structure et du fonctionnement des systèmes expérimentés sur l’IE ASTER Mirecourt
No full textfr@ Ce jeu de données représente l’organisation et la répartition des flux de matières au sein des systèmes expérimentés sur l’installation expérimentale de Mirecourt. Le système est organisé en différents compartiments dont l’organisation s’appuie sur le système le plus diversifié. Ainsi, le système est décrit par 2 compartiments de production primaire (prairies permanentes et surfaces labourables), 3 compartiments de productions animales (bovins laitiers, ovins allaitants et porcs engraissement) ainsi que 3 compartiments de stockage (fourrages, effluents d’élevage et grains). Les intrants, ventes et pertes permettent d’identifier les interactions des systèmes avec leur environnement. Les flux sont exprimés en kgN/an.
Les données décrivent différents systèmes issus des expérimentations systèmes. Un premier lot de matrices décrit le système herbager (SH) et le système de polyculture-élevage (SCPE) expérimentés entre 2006 et 2015 (seules les années 2011 à 2015 sont présentées). Un second lot de matrice décrit le système diversifié (TEMPO) mis en place à partir de 2016 (seules les années 2018 à 2020 sont présentées).
Les données proviennent des systèmes d’information de l’installation expérimentale, et en particulier de la base de données ASTER-ix (Application pour la Saisie et le Traitement des Evènements Recensés sur l’Installation eXpérimentale – IDDN.FR.001.130016.000R.P.2010.000.10300) et de la base de données ALADIN pour caractériser les flux de matières entre les compartiments décrivant le système. Les analyses réalisées régulièrement sur le système (composition des fourrages, effluents d’élevage, qualité des productions animales et végétales, dépôts atmosphériques…) ont été complétées par des références issues de la bibliographie (notamment la base de données Animal Feed Ressources Information System). La fixation d’azote symbiotique par les légumineuses et les pertes par lixiviation et volatilisation ont été modélisées à partir de travaux de recherche adaptés aux systèmes étudiés (Anglade 2015, Peyraud et al, 2012).en@ This dataset represents the organisation and distribution of material flows within the systems tested at the Mirecourt experimental farm. The system is organised into different compartments based on the most diversified system. Thus, the system is described by 2 primary production compartments (permanent grasslands and arable land), 3 animal production compartments (dairy cattle, suckling sheep and fattening pigs) as well as 3 storage compartments (fodder, livestock effluents and grains). Inputs, sales and losses allow to identify the interactions of the systems with their environment. Flows are expressed in kgN/year.
The data describe different systems from system experiments. A first batch of matrices describes the grassland system (SH) and the mixed crop-livestock system (SPCE) experimented between 2006 and 2015 (only the years 2011 to 2015 are presented). A second batch of matrices describes the diversified system (TEMPO) implemented from 2016 (only the years 2018 to 2020 are presented).
Data were obtained from the experimental facility's information systems, in particular from the ASTER-ix database (Application pour la Saisie et le Traitement des Evènements Recensés sur l'Installation eXpérimentale - IDDN.FR.001.130016.000R.P.2010.000.10300) and the ALADIN database to characterize the material flows between the compartments describing the system. Regular analyses of the system (forage composition, livestock manure, quality of animal and plant production, atmospheric deposition, etc.) were supplemented by references from the literature (in particular the Animal Feed Resources Information System database). Symbiotic nitrogen fixation by legumes and losses by leaching and volatilization were modeled from research works adapted to the studied systems (Anglade 2015, Peyraud et al, 2012)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
