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
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.

Comparison between frame in CL-wood and light beams
No full textIn the beginning stage when a building is to be constructed it can be difficult to choose the material for the supporting frame. Today there is a lot of different materials with different properties, each material often has good properties while at the same time there is a worse property, heavy weight for example. The growing debate about climate change has led to an increased use of building with wood, as it is positive from a climate perspective. Structor Byggteknik Umeå AB has in their work as construction consultants received questions from customers who want to know more about the differences between cross-laminated wood (CL-wood) and light beams. These questions are the foundation to this project, in which the differences between how the chosen material affects the living area will be compared. The project will also include a comparison to see which material that consumes the most amount of wood. The aspect of climate impact will also be compared in the unit CO2-equivalents, which is a topical question today. To produce the data that will be used to compare the material two buildings where dimensioned, one with CL- wood and one with light beams. To perform the dimensioning a reference building made with concrete was used, from which a section of the building was retrieved as well as loads. In consultations with Structor, requirements were set for sound, U-value, and fire for the buildings that were dimensioned. The load countdown was performed with the program Statcon structure where the most loaded walls and floor slabs were checked in both serviceability limit state (SLS) and ultimate limit state (ULS). From the structure of the floor slabs and walls the amount of wood per 1 m2 were calculated for every building component. With known wall thickness two 3D-modells were produced, one for each material. From the 3D-modells the living area was compared. For the comparison of climate impact two climate declarations including module A1-A5 was created with the construction sector’s environmental calculating program (BM). The comparison of the living area resulted in a difference of 0,8 m2 per floor where the CL-wood was the larger one, despite that the exterior walls and the dividing walls were thicker for the building with CL-wood. This might be because the load-bearing inner walls in the light beam building were a lot thicker than the inner walls in the CL-building. The material consumption was compared by calculating the volume of wood for 1 m2 for every building component. The result showed a difference of 327 % where the light beam building consumed a smaller amount of wood. Most likely this is because the CL-slabs are homogeneous wood elements which increase the amount of wood per m2, while the light beam in the construction is placed with a center distance of 600 mm. One climate declaration was made for each building, the climate impact was compared both component against component and with a total of 1 m2 of every building component. The result showed that when all the building components is compared the CL-building generated a higher climate impact. A closer comparison between component against component shows that the floor slabs in the CL-building has a lower climate impact than the floor with light beams. The conclusion of the project is that both CL-wood and light beams have its advantage, but it can be difficult to say exactly which material is the better one. Despite this, light beams have two advantages in this project while CL-wood only has one. To facilitate the choice a check should be done where all the conditions and requirements are listed. With that list it’s possible to compare which material suits for the specific project.I den initierande fasen för en byggnad kan det vara svårt att välja material för den bärande stommen. Idag finns det många olika material med olika egenskaper, varje material har någon eller några fördelar samtidigt som de också har en eller flera sämre egenskaper. I och med den växande klimatdebatten har allt fler valt att bygga med trä, då det är positivt ur ett klimatperspektiv. Structor Byggteknik Umeå AB (hädanefter Structor) har i sitt arbete som byggnadskonsulter fått frågor från kunder som vill veta mer om skillnaden mellan KL-trä och lättbalkar. Structor vill ha ett underlag för att kunna visa sina kunder vilket av de två alternativen som lämpar sig bäst för deras projekt. Detta är de som låg till grund för det här projektet där KL-trä och lättbalkar jämfördes med aspekter på hur materialvalet påverkar boarean samt materialåtgången av volymen trä. Även en jämförelse av klimatpåverkan i CO2-ekvivalenter utfördes för att belysa skillnader i ett dagsaktuellt ämne. För att ta fram det underlag som senare användes för att bedöma materialens för- och nackdelar dimensionerades två byggnader, en byggnad med KL-trä samt en byggnad med lättbalkar. Dimensioneringen utgick från en betongbyggnad som Structor dimensionerat under 2021, från den hämtades en sektion av byggnaden som gav bestämda mått samt laster. I samråd med Structor sattes krav på ljud, U-värde och brand för byggnaderna som dimensionerades. Lastnedräkningen utfördes med hjälp av programmet Statcon där de mest belastade väggarna och bjälklagen sedan kontrollerades i både bruksgränstillstånd samt i brottgränstillstånd. Den färdiga uppbyggnaden av bjälklag och väggar användes för att sammanställa mängden trä för 1 m2 av respektive byggdel. Med kända väggtjocklekar 3D-modellerades en våning av varje byggnad, 3D-modellerna användes därefter för att jämföra boarean. För jämförelsen av klimatpåverkan skapades en klimatdeklaration för modul A1-A5 med byggsektorns miljöberäkningsprogram (BM). Boarean som jämfördes utifrån 3D-modellerna resulterade i en skillnad på 0,8 m2 vilket blev cirka 0,47 % per våning där KL-byggnaden var den större, trots att ytterväggarna och de lägenhetsavskiljandeväggarna var tjockare i KL-byggnaden. Detta kan bero på att de bärande innerväggarna var tjockare för lättbalks-byggnaden, vilket var den avgörande faktorn för boarean. Materialåtgången jämfördes genom att beräkna volymen trä för 1 m2 av varje byggdel för respektive byggnad. Resultatet visade en skillnad på 327 % där lättbalksbyggnaden förbrukade mindre trä. Detta beror mest sannolikt på att KL-skivorna är homogena träelement som ökar mängden trä / m2, medan väggar med lättreglar endast placeras med centrumavstånd på 600 mm. En klimatdeklaration för varje byggnad gjordes i BM, klimatpåverkan jämfördes både byggdel mot byggdel och totalt där 1 m2 av varje byggdel sammanställdes. Resultatet visade här att KL-byggnaden genererade en högre klimatpåverkan när alla byggdelar jämförs. Granskas i stället varje byggdel för sig så har bjälklagen i KL-byggnaden en lägre klimatpåverkan än bjälklagen i lättbalksbyggnaden. Slutsatsen från projektet är att KL-trä och lättbalkar har sina fördelar och att det är svårt att dra en tydlig slutsats och säga vilket av dem som är det bättre. Dock så har lättbalkar två fördelar i detta projekt och KL-trä har endast en. Kontroll av förutsättningar och krav bör göras för varje projekt där materialet sedan jämförs för att ta reda på vilket som lämpar sig bäst för just det projektet
