Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
Strategisk tilpasning i skiftende landskap En kvalitativ studie av én entreprenørs respons på økende kompleksitet i byggebransjen
No full textDenne masteroppgaven undersøker hvordan den lokale entreprenøren Eiendom & Norske Hus AS utvikler og implementerer strategier for å navigere seg gjennom skiftede krav og forventninger i markedet. Måten det blir gjort på er å undersøke hvordan en lokal entreprenør i Tromsø gjør konkrete tilpasninger i sin daglige drift for å bli mer og opprettholde egen konkurransedyktighet. Derfor er studiens problemstilling:
«Hvordan navigerer entreprenører i bygge- og anleggsbransjen stadig mer komplekse anbudsprosesser, og hvilke faktorer påvirker deres strategiske valg?»
Problemstillingen blir svart på gjennom en kvalitativ studie hvor det har blitt gjennomført en rekke dybdeintervjuer både internt i bedriften, men også av oppdragsgivere som bidrar til å forme hvordan ENH navigerer seg strategisk i markedet. For å supplere dybdeintervjuene ble det også gjennomført en triangulering for å få en bredere forståelse av deres strategi. Derfor ble det også gjennomført dokumentgjennomgang og søk i offentlige registre for å både bekrefte det som ble redegjort i intervjuene, og supplere med faktaopplysninger.
For å belyse funnene i denne studien har jeg jobbet ut fra noen teoretiske rammeverk: Framvoksende strategi, interessentteori og institusjonell teori. Disse teoriene har hjulpet meg å skape en forståelse for hvordan bedriftens endringer og valg kan forklares akademisk. Med hjelp av GIOIA-metode satt jeg igjen med 4 sentrale funn angående ENHs navigering i markedets økende kompleksitet: (1) Endringsfokus, (2) Omdømmefokus, (3) fokus på mobilisering av arbeidsstokken og intern kompetanse og (4) risikofokus. Sentrale funn viser at ENH har gjort mange endringer de siste årene for å imøtekomme markedets krav, og deres strategi virker å være framvoksende heller enn en nedskrevet langsiktig plan. Det kommer frem mange interne, eksterne og markedsmessige årsaker til at endringene skjer, men i all hovedsak drives endringene som gjøres av et ønske om å være proaktiv i tilnærmingen heller enn reaktiv. Konklusjonen er at deres måte å navigere seg i stadig mer komplekse anbudsprosesser er å la krav styre investeringene, samtidig som eksterne og interne interessenters forventninger skaper nyanser i deres måte å drive på
Utilization of Phasor Measurement Units in Hybrid Linear State Estimation
No full textThe Phasor Measurement Unit (PMU) introduces new functionality to the measurement spectrum, with accurate time tagging and synchronization capability, and is thus the next step in the technological evolution of state estimation in electrical power systems. This thesis presents the theoretical basis behind a two-pass hybrid linear state estimation model, the aim of which is to utilize PMU measurements in conjunction with classical state estimation. Following this, the construction of a hybrid linear state estimator application is discussed. Numerical simulation has been conducted to evaluate the feasibility of the model as a way of utilizing the increasing availability of synchrophasor measurements to improve state estimation. The results indicate a significant potential improvement of state estimation, especially in aspects of monitoring dynamic behaviour within the system

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
