Environmental assessment of urban area trip purposes in France with Life Cycle Analysis
No full textLes déplacements de personnes et de marchandises sont responsables d’une part importante des impacts environnementaux à l’échelle de la ville. Cette thèse part des hypothèses que, les impacts environnementaux des phases situées en amont ou en aval de la phase d’usage ne sont pas négligeables et que l’étude différenciée des besoins de mobilité peut apporter un éclairage nouveau aux méthodes traditionnelles d’évaluation. La façon de répondre à chaque besoin induit, a priori, des impacts environnementaux différents. Ces derniers sont calculés à l’aide de la méthode d’Analyse de Cycle de Vie. La méthodologie a été développée sur un cas d’application : les émissions de GES de l’Agglomération de Saint-Etienne afin de se confronter à la réalité du terrain et de se procurer des données spécifiques. Ce cas d’application a donné une première série de résultats, confirmant à la fois la part non négligeable d’impacts hors phase d’usage et la disparité des émissions pour une personne.kilomètre selon le besoin de déplacement. Ensuite, une proposition de typologies urbaines a été faite en réalisant une Analyse en Composantes Principales, couplée à une Classification Ascendante Hiérarchique, sur les grandes aires urbaines de France, sur des variables influentes pour la mobilité. Trois classes d’aires urbaines ont été étudiées. La méthodologie a été appliquée aux données des Enquêtes Ménages Déplacements de Bordeaux, Toulon et Valenciennes. Des disparités sont observées pour certains motifs et il est possible de calculer des marges de progression pour chaque agglomération. Enfin, l’utilisation de l’ACV, multicritère a également révélé la nécessité de travailler avec plusieurs indicateurs.Transportation of goods and people is known as a key environmental impact contributor in a city. However, traditional impact assessment methodologies don’t consider environmental issues all over the life cycle. The cause of a trip is also rarely taken into account in an environmental assessment. This thesis aims at proposing a new impact assessment methodology that considers the influence of indirect emissions (using Life Cycle Assessment (LCA) methodology) and causes of trips on the environmental footprint. Two main hypotheses are settled at the beginning: the environmental impacts of mobility do not only occur during the use phase (the trip by itself) but all over its life cycle. Also the trip purposes may change the choice of way to travel and consequently affect environmental impacts. The global Functional Unit (FU) is “transport people and good in a French urban area during a year” and is divided in intermediate FU referring to each trip purposes, such as “allow commuter trips in a French urban area during a year”. The methodology was developed, tested and validated through a real case: the agglomeration of Saint-Etienne (France). During this phase, mobility territorial actors were met and real data provided that allows facing methodology to possible field limitations. This application case shows first results. First, it confirms importance to consider impacts all over the life cycle (17% of GHG emissions occur out of the use phase). Second, it shows significant differences of emissions by person.kilometer between trip purposes categories. Then a typology of urban area was proposed based on literature about travel determinants. Principal Component Analysis used on French big urban areas (more than 250 000 inhabitants) identified 5 classes. The methodology was applied to three of them (Bordeaux, Toulon and Valenciennes) using data from a standardized survey on households and mobility in order to compare them. It shows disparities on global results partly due to total annual travel distances. The trip purposes differentiation also shows important differences between urban areas. For each cause trip category and emission reduction potentials were calculated for each urban area by extrapolating differences for a pkm to the total annual distance for the trip. This can provide helpful information to deciders. Finally, the need to provide a multicriteria evaluation that is provided by LCA was committed. However methodological improvement would be necessary to better reflect local and regional impacts in LCA
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
