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
Lisäosien välinen vuorovaikutus laajennettavissa ohjelmistoalustoissa
No full textIn the recent decades, it has become customary that feature-rich software products are designed to be extendable with external components, plug-ins. While the architectural pattern enabling this design has become well established, a substantial limitation has been recognized: it only poorly supports interoperation between plug-ins, making plug-in dependencies difficult to maintain.
Practice has shown that in many systems designed in this way, plug-in interoperation is nevertheless needed. This raises the question: How could plug-in interoperation be designed to keep the problems that it causes in check?
This thesis tackles the question by analyzing the problems of plug-in interoperation. It turns out that dependencies between plug-ins are prone to incompatibility issues that are hard to predict and even harder to handle when they occur. Furthermore, due to the dynamic nature of the plug-in architecture, the integrity of a system with interdependent plug-ins is difficult to assure when releasing new versions.
To these design problems of plug-in interoperation, I search for potential solutions among the design patterns and practices of the software architecture literature. I consider the issue from the perspectives of both a plug-in and and the system it extends. Based on this analysis, I argue that by applying good software engineering practices, such as explicitly defined programming interfaces, controlled versioning, and sound code structure, software designers can remarkably reduce the complexity caused by plug-in interdependencies.
As a concrete example of a plug-in system, I study the IntelliJ IDE platform developed by JetBrains, and observe how plug-in interoperation materializes in it. As a case study, I present an IntelliJ plug-in that I co-developed as part of a team and review its design in the light of plug-in interoperability issues.Viime vuosikymmeninä on tullut tavanmukaiseksi, että laajatoiminnalliset ohjelmistotuotteet suunnitellaan laajennettaviksi ulkoisilla lisäosilla. Tähän tarkoitukseen usein käytetty arkkitehtoninen suunnittelumalli on vakiintuneisuudestaan huolimatta havaittu rajoittuneeksi: se ei kunnolla tue lisäosien välistä vuorovaikutusta tehden lisäosien välisten riippuvuuksien ylläpidosta hankalaa.
Kokemus on osoittanut, että monissa tällä tavoin suunnitelluissa ohjelmistoissa lisäosien välistä vuorovaikutusta kuitenkin tarvitaan. Tästä seuraa kysymys: Kuinka lisäosien välinen vuorovaikutus tulisi suunnitella, jotta siitä aiheutuvat ongelmat kyettäisiin hallitsemaan?
Tämä diplomityö lähestyy kysymystä analysoimalla lisäosien väliseen vuorovaikutukseen liittyvää ongelmakenttää. Osoittautuu, että lisäosien väliset riippuvuudet ovat alttiita yhteensopivuusongelmille, joita on hankala sekä ennustaa että jälkikäteen selvittää. Lisäosa-arkkitehtuurin dynaamisesta luonteesta johtuen lisäosien välisiä riippuvuuksia sisältävien järjestelmien eheyden varmistaminen on vaikeaa uusia versioita julkaistaessa.
Näihin lisäosien väliseen vuorovaikutukseen liittyviin ongelmakohtiin etsin mahdollisia ratkaisuja kirjallisuudessa tunnetuista suunnittelumalleista ja käytänteistä. Tarkastelen kysymystä niin lisäosan kuin alustaohjelmistonkin näkökulmasta. Analyysiini tukeutuen esitän, että ohjelmistosuunnittelijat voivat huomattavasti vähentää lisäosien välisistä riippuvuuksista aiheutuvaa mutkikkuutta soveltamalla ohjelmistokehityksen hyviä käytänteitä, kuten tarkasti määriteltyjä ohjelmointirajapintoja, hallittua versiointia ja hyvää lähdekoodin rakennetta.
Konkreettisena esimerkkinä laajennettavasta ohjelmistosta käsittelen JetBrainsin kehittämää IntelliJ-ohjelmointiympäristö-alustaa ja tutkin, miten lisäosien välinen vuorovaikutus siinä toteutuu. Tapaustutkimuksena esittelen ryhmämme kehittämän IntelliJ:n lisäosan ja arvioin sen ohjelmistoarkkitehtuuria lisäosien välisen vuorovaikutuksen kannalta
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
