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

No full textAppropriate 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
A Concept-Oriented Data Modeling and Query Language Approach to Next Generation Information Systems
No full textSeuraavan sukupolven tietojärjestelmissä (Next Generation Information systems; NGISs) tiedon dataorientoituneet, funktionaaliset ja deduktiiviset piirteet integroituvat toisiinsa. Dataorientoituneet piirteet määrittävät mitä tietoa tallennetaan ja kuinka tiedon rakenteelliset suhteet organisoidaan. Funktionaaliset piirteet liittyvät tallennetun tiedon laskennalliseen käsittelyyn. Deduktiiviset piirteet määrittävät uutta tietämystä tallennetusta tiedosta. Tutkimuksessa käsitellään näitä piirteitä ja niiden integrointia tiedon mallintamisen ja kyselykielten näkökulmasta.
Yleistyssuhde (is-a relationship), osa-kokonaisuussuhde (part-of relationship) ja assosiaatio ovat kolme perussuhdetta sovellusalueen mallintamisessa. Tutkimuksessa tarkastellaan yllä mainittuja piirteitä näiden suhdetyyppien kannalta. Osa-kokonaisuussuhde on tutkimuksessa keskeisin suhdetyyppi. Tämän sovelluksena tarkastellaan fyysisiä kokoonpanoja.
Rakenteellisten tietokantojen lisäksi usein on välttämätöntä käsitellä sovelluksiin liittyvää tekstimuotoista informaatiota. Siksi tutkimuksessa ehdotetaan, että tekstimuotoinen informaatio ja siihen liittyvä käsittely pitäisi sisällyttää NGIS-järjestelmiin. Tutkimuksessa tekstidokumentit käsitellään XML-muodossa. Tämä mahdollistaa tekstimuotoisen informaation hyödyntämisen spesifioitaessa funktionaalisia ja deduktiivisia primitiivejä. Tutkimuksessa annetaan sekä datakeskeinen että dokumenttikeskeinen näkökulma XML:ään. Datakeskeisessä näkökulmassa XML- elementtejä käsitellään kuten tietokantakyseissä kun taas dokumenttikeskeisessä näkökulmassa niitä käsitellään tiedonhaun menetelmin.
Tutkimuksessa kehitetään RDOOM-menetelmä (Relational Object-Oriented Modeling) mallintamaan kaikkia keskeisiä piirteitä NGIS-järjestelmissä. RDOOM on käsiteorientoitunut mallintamismenetelmä, joka on suunnattu tarjoamaan sellaisia mallintamisprimitiivejä, joihin sovellusspesifejä käsitteitä ja rakenteita voidaan upottaa. Käyttäjän näkökulmasta kyselyn muodostaminen muistuttaa sovellusspesifisten käsitteiden ja rakenteiden kombinointia sekä ehtojen antamista niiden välillä. Konventinalisten ekstensionaalisen kyselyiden lisäksi tutkimuksessa käsitellään intensionaalisia kyselyjä, yhdistettyjä extensionaalis-intensionaalisia kyselyjä sekä XML-elementtien relevanssilajittelua.In Next Generation Information Systems (NGISs) data-oriented, behavioral and deductive aspects of data are integrated with each other. Data-oriented aspects determine what data are stored and how structural relationships among them are organized. Behavioral aspects are associated with calculations (functionalities) of stored data. Deductive aspects define derivation of new knowledge from the stored data. This study deals with these aspects and their integration from the modeling and related querying perspective of NGISs.
The is-a relationship, the part-of relationship and the association are three fundamental relationships among data in the real world. Therefore, in this study different aspects of data are considered on the basis of these relationships. Special attention is paid to the development of an advanced modeling and manipulation approach to complex part-of relationships, called physical assemblies. In addition to data in the structured databases it is also often necessary to manipulate textual information in advanced applications. Therefore we propose that the textual information and its related manipulation should be included in NGISs. In this study we assume that textual documents are represented by XML. This affords the possibility of also utilizing the information in XML documents in the specification of the behavioral and deductive aspects of data. Further we offer both the data-centric and document-centric view of XML. In the data-centric view XML elements are manipulated as in database queries, whereas in the document-centric view they are manipulated as in information retrieval. In this study we develop and extend the RDOOM (Relational Object-Oriented Modeling) method for modeling all essential aspects in NGISs. RDOOM is a concept-oriented modeling method intended to offer such modeling primitives in which application-specific concepts and structures can be embedded. From the viewpoint of the user, query formulation based on our approach resembles a combination of applications-specific concepts and structures and specification of conditions among them. In addition to conventional extensional queries the study deals with intensional queries, extensional-intensional queries and relevance ranking of XML elements
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
