We describe the development of 13 microsatellite markers for both species, based on 454 pyrosequencing technology. The number of alleles per locus ranged from 2 to 11 in A. alosa and from 4 to 13 in A. fallax. Gene diversity ranged from 0.364 to 0.800 for A. alosa and 0.226 to 0.849 for A. fallax. These markers will help in conservation genetics studies such as assessing the extent of population decline, defining appropriate conservation units and monitoring reintroduction programs
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
BE likely to and BE expected to, epistemic modality or evidentiality? Markers of (non)commitment in newspaper discourse
No full textInternational audienceThis paper deals with the contribution of BE likely to and BE expected to to the expression of point of view in newspaper discourse. On the basis of a unified and contextualized account of those structures’ operating modes, it is argued that they both have modal and evidential values – a combination which, by allowing the speaker to express an opinion while distancing him/herself from it, might explain their extensive use in journalistic texts. Yet, it is also shown that each marker has specific characteristics which, on the one hand, entail different contextual constraints that partly explain their coexistence as well as their diverging uses – especially when other markers of modality or reported speech are involved – and, on the other hand, inform the speaker’s choices depending on his/her level of commitment to the evaluation
Commitment in newspaper discourse and its evolution : BE X TO structures in contemporary British English
No full textCette thèse s'intéresse à la prise en charge énonciative jans le discours journalistique à travers l'étude de vingt structures BEX TO de l'anglais britannique contemporain dont BE able to, BE expected to, BE likely to, BE forced to, BE hard to, BE said to). Ce~ structures adjectivales et participiales présentent des affinités avec les domaines connexes de la modalité et de I'évidentialité et jouent ainsi un rôle important dans l'articulation de différents points de vue dans les textes journalistiques. Elles appartiennent cependant à un ensemble mal délimité, infra-catégoriel, et posent en ce sens des problèmes de description qui font qu'elles sont très peu abordées dans la littérature. Pour répondre à ce manque, nous proposons une analyse unifiée des phénomènes syntaxiques, sémantiques et pragmatiques mis en jeu car ces expressions quasi-modales dans le cadre de la ihéorie des Opérations Prédicatives et Énonciatives. lia l'élaboration de formes schématiques s'appuyant sur l'analyse d'un corpus d'énoncés authentiques (The Independent 1992-2009), nous démontrons que BEx TO est la trace d'une double opération d'attribution de propriété et de modalisation qui lui confère des propriétés à la fois factuelles et subjectives. Cette ambivalence des structures apparaît comme un facteur d'explication de leur emploi fréquent dans le discours journalistique, où elles contribuent à la mise en place de différents modes de prise en charge en interaction avec leur co-texte. Afin d'éclairer autrement le fonctionnement de ces marqueurs, nous traitons pour finir de leur évolution récente, que nous mettons en regard avec une étude critique de la théorie de la grammaticalisation.This thesis deals with commitment in newspaper discourse via the case study of twenty BE X TO structures in present-day British English (e.g. BE able to, BE expected to, BE likely to, BE forced to, BE hard to, BE said to). These adjectival and participial constructions are linked to the interrelated domains of modality and evidentiality, and as such they play an important role in the organisation of points of view in news texts. Yet they have been the object of very little research until recently, probably because they belong to an ill-defined grouping of expressions which seem to resist categorisation and pose as a consequence a number of descriptive issues. The goal of the present work is to remedy this void by providing a unified analysis of the syntactic, semantic and pragmatic phenomena involved in the uses of these quasi-modal markers, through the lens of the Theory of Predicative and Enunciative Operations. The schematic forms formulated on the basis of a detailed analysis of the Independent (1992-2009) corpus thus reveal that BE x TO structures are complex operators functioning as markers of property attribution and modalisation at the same time. Because of this double role, they are both factual and subjective, which probably contributes to their high frequency in newspaper discourse. It is also shown that depending on the co-text and the properties of individual structures, they are used by the speaker to express different types of stance or commitment. Finally, the uses of BEx TO structures are put into perspective via a study of their evolution in recent years. The data is considered with respect to grammaticalisation theory in a critical assessmen
BE able to and the categorization of modal markers in English: A corpus-based study
No full textInternational audienceThe aim of this paper is to investigate the role of BE X TO structures in English via the analysis of the quasi-modal BE ABLE TO. Based on previous accounts of the marker and its comparison with modal auxiliary CAN, defining characteristics are identified and contrasted with the description of other BE X TO structures such as BE ALLOWED TO and BE LIKELY TO. Consequently, the availability of non-finite forms along with property attribution and goal orientation stand out as unifying properties of the BE X TO quasi-modal category, which occupies a singular place within the modal system of English
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
