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
Characteristics and presence changes of Natura habitat types 7210 and 7230 (calcareous and alkaline fens) in small lakes of Estonia
No full textKäesolevas töös on lühike ülevaade soo mõistest, selle tekkest ning põhjalikumalt madalsoost väikejärvede ääres. Madalsoid ning nende taimestikku pole Eesti väikejärvedelt kogutud andmestiku põhjal siiani käsitletud. Et tegemist on kiiresti väheneva elupaigaga, oleks vaja saada ettekujutust, millisel määral neid on järvede ääres. Töö käsitleb NATURA elupaigatüüpe 7210 ja 7230 ning seda, kas on võimalik neid eristada väikejärvede ääres.
Töö eesmärkideks on:
1. Selgitada, kas elupaigatüübid 7210 ja 7230 eristuvad allikarohkete ja/või karbonaatsel aluskivimil tekkinud väikejärvede veepiiril olevais soodes.
2. Millised elupaigatüüpide 7210 ja 7230 kooslustest järvede ääres esinevad?
3. Kas on toimunud muutusi, mille põhjal võib oletada varem järvekallastel esinenud liigirohkete madalsoode degradeerumist?
Töös kasutati Limnoloogiakeskuse väikejärvede andmebaasis (2011. a. seisuga) olevate 509 järve andmetest 68 veekogu omi, mille veepiiril võis oletada vaatlustaluste elupaigatüüpide olemasolu. Lisaks käis töö autor ka ise mõnede Lõuna-Eesti orujärvede ääres ning kirjeldas sealset taimekooslust. Andmeanalüüsiks on leitud liikidele keskmised ohtrused igas järves, mille põhjal on tehtud klasteranalüüs. Samuti on võrdlus mõõdukalt kareda- ja karedaveeliste järvede ja pehmeveeliste järvede taimestiku vahel.
Elupaigatüübi 7210 Lääne-mõõkrohu Cladium mariscus ja raudtarnakoosluste (Caricion davallianae) liikidega lubjarikast madalsood on võimalik eristada peamiselt Lääne-Eesti järvedes ning rannikujärvedes. Elupaigatüüpi 7230 Aluselised ja nõrgalt happelised liigirikkad madalsood Limnoloogiakeskuse väikejärvede andmebaasis olevate taimede järgi eristada ei saanud. Põhjuseks võiks lugeda teatud taimerühmade osas (samblad, puud-põõsad) puudulikku andmebaasi ja/või selle elupaiga tugevat vähenemist Eestis väikejärvede ääres.
Elupaigatüüp 7210 kooslustest sai klasteranalüüsi tulemusena eristada lääne-mõõkrohu kooslust (Cladietum marisci), mis esines 13. järves, millest enamus järvi kuuluvad Läänesaarte vesikonda ning on kareda- või mõõdukalt karedaveelised ja tumeda värvusega. Tulemuste järgi võib ka oletada, et mõõkrohu kooslus on varasemalt laiemalt levinud Ida-Eestis, kuid praegu esineb see siiski Lääne-Eesti saartel ning rannikujärvedes. Elupaigatüübi 7230 kooslustest sai eristada, toetudes andmebaasile ning mitte klasterdamisele, luhttarna kooslust (Caricetum elatae) ja ahtalehise villpea kooslust (Eriophoretum angustifolii). See elupaigatüüp esineb 44. järves, millest enamus on kareda- või mõõdukalt karedaveelised ning
heleda värvusega. Üle poolte järvedest kuuluvad Peipsi alamvesikonda, mille järgi võib öelda, et see tüüp on pigem Ida-Eestis.
Nii andmebaasi põhjal tehtud analüüsi kui ka enda kogutud andmete põhjal võib väita, et mõõdukalt kareda- ja karedaveeliste järvede ääres esineb kohati liigirikast madalsood, kuid selle floora vajab veel täiendavat uurimist nii liigirikaste madalsoode klassifitseerimise kui ka kaitse seisukohalt. Varem esinenud liigirohkete madalsoode vähenemises võib suuresti süüdi olla pilliroo (Phragmites australis) ohtruse suurenemine ning järvede alandamine.
Kõige sagedasemate kaldaveeliikide võrdlemisel pehmeveelistes järvedes tähtsamate liikidega selgus rida liike, mida võib pidada meie järvedes universaalseteks. Selgusid ka liigid, mis on iseloomulikud just mõõdukalt kareda- ja karedaveelistele järvedele.The aim of this bachelor’s thesis was to describe NATURA habitat 7210 and 7230, also if it’s possible to distinguish them from small lakes with moderately hard or hard water. To do that, the author used the database of small lakes and also visisted some of the Southern Estonian lakes to describe their flora. The author found frequencys for each species and also did the cluster analysis. There is also a comparision with soft-water lakes.
Habitat 7210 calcareous fens with Cladium mariscus and species of the Caricion davallianae is mostly in the lakes of Western Estonia and in coastal lakes. Habitat 7230 alkaline fens didn’t distinct based on the database. The reason might be regarded as lack of data in certain plant groups (mosses, trees, shrubs) and/or in a strong decrease of this habitat.
Using cluster analysis it was possible to distinguish Cladium mariscus habitat type 7210, which occured in 13 lakes of 68, most of which belong to Western Estonia and have hard or moderately hard water and are dark-coloured. Based on the results it can be said that Cladium mariscus was more widespread earlier in Eastern Estonia, but now it appears in Western Estonian islands and in coastal lakes. It was possible to distinguish Caricetum elatae and Eriophoretum angustifolii of habitat type 7230 based on their frequency, not by cluster analysis. This habitat type was presented in 44 lakes, most of them with hard or moderately hard water and light-coloured. They are mainly situated in the sub-basin of the lake Peipsi and it can be said that this type is most common in Eastern Estonia.
Several lakes with moderately hard and hard water have species-rich fens, but this fen type needs more investigaion regarding both classification as well as the protection. Increase of Phragmites australis abundance and the lowering of lakes could be the reasons why this type of fen is decreasing.
In comparision with soft-water lakes, there were revealed many species that are universal and very frequent in all types of our lakes. This work also shoved, which species are specific to lakes with hard or moderately hard water
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
