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
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
Malčer za traktore manje snage
Full text linkPrikazani završni rad integrira cjelokupni postupak istraživanja, razvoja i konstruiranja uređaja za usitnjavanje trave i sitnijeg granja. U radu je napravljena analiza patenata i već postojećih proizvoda te njihovo vrednovanje. Funkcijskom strukturom se glavni problem podijelio na podfunkcije kojima su u morfološkoj matrici dodijeljeni mogući principi rješenja. Kombinacijom rješenja dobivena su 2 koncepta koja su vrednovana. Za odabrani koncept, napravljen je proračun i odabir standardnih dijelova, kreirani su 3D modeli te u konačnici, dokumentacija

This work is analyzing patents and already existing products on the market and making their evaluation. With the function structure, the main problem was divided into subfunctions that are assigned with possible solutions principle in the morphological matrix. With combination of solutions, two concepts were evaluated. For the chosen concept, calculation and selection of standard parts have been made, 3D models are created and, ultimately, documentation
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
Tractor operated device for harvesting hazelnut
No full textRučna berba lješnjaka je vrlo iscrpljujući posao koji zahtjeva veliki broj radnika kako bi učinkovitost u radu bila što veća. Kako bi se smanjio izrazito visoki broj radnih sati berača u voćnjacima relativno velikih površina, primjenjuju se razni oblici i načini mehanizacije u berbi lješnjaka, kao i u njihovom skladištenju i sušenju.
U ovom diplomskom radu, napravljeno je detaljno istraživanje i vrednovanje postojećih uređaja za berbu lješnjaka koji se mogu pronaći na današnjem tržištu, razlaganje pojedinih funkcija berbe te dodavanje odgovarajućih mogućnosti rješenja svakom problemu. Slijedi izrada koncepata koji su detaljno opisani i vrednovani prema odgovarajućim kriterijima uz pripadajuće težinske faktore. Za odabrani koncept, izrađen je kontrolni proračun te naposljetku, računalni 3D model s pripadajućom tehničkom dokumentacijom.Hand-picking of hazelnuts is a very difficult job and it is labour-intensive if maximum efficiency is to be achieved. In order to reduce the extremely high number of hours pickers work in orchards of relatively large areas, various forms and methods of mechanization are used n the hazelnut harvesting, storage and drying.
In this master's thesis, a detailed research and evaluation of existing devices for harvesting hazelnuts that can be found on the market are made individual harvesting functions are analysed and appropriate solutions to each problem are proposed. Furthermore, the proposed concepts are described in detail and evaluated according to appropriate criteria with the corresponding weighting factors. A control calculation is made for the selected concept and, finally, a computer 3D model with related technical documentation is developed
