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
Reciklacija ireverzibilnih termokromnih tiskarskih boja
No full textTermokromne tiskarske boje su posebne kromogene boje koje mijenjaju svoje obojenje izlaganjem pri određenoj temperaturi. Temperaturni raspon u kojem se odvija prijelaz boje obično se naziva temperatura aktivacije. Promjena boje može biti ireverzibilna (nepovratna) ili reverzibilna (povratna). Svojstvo ireverzibilne promjene boje u odnosu na temperaturno izlaganje tijekom vremena, omogućuje razvoj brojnih indikatora. Kao takvi se mogu koristiti za praćenje stanja skladištenja i prijevoza proizvoda osjetljivih na temperaturu, kao što su ohlađena i smrznuta hrana, lijekovi, kemikalije osjetljive na temperaturu ili biološki materijali, itd. Ostale primjene uključuju praćenje procesa koji zahtijevaju izlaganje visokoj temperaturi kao što je sterilizacija i kuhanje. Budući da je formulacija tiskarske boje bitan čimbenik u deinking procesu, cilj ovog istraživanja utvrđivanje efikasnost recikliranja ireverzibilnih termokromnih otisaka. Termokromne boje razlikuju se od konvencionalnih tiskarskih boji u formulaciji i veličini pigmenata zbog prisutnosti mikrokapsula koje su mnogo veće od konvencionalnih pigmentnih čestica. Kako bi se objasnilo ponašanje ovih boja u procesu recikliranja, također će biti ispitana hidrofobnost uzoraka, kao jednoj značajnog faktora u procesu recikliranja.Thermochromic printing inks are special chromogenic inks that change their colour by exposure at a certain temperature. The temperature range in which the color transition occurs is usually called the activation temperature. The color change can be irreversible or reversible. The property of irreversible ink change over temperature exposure over time allows the development of numerous indicators. As such, they can be used to monitor storage conditions and transport of temperature sensitive products such as chilled and frozen foods, medicines, temperature sensitive chemicals or biological materials, etc. Other applications include process monitoring that require high temperature exposure such as sterilization and cooking. Since the printing ink formulation is an important factor in the deinking process, the aim of this research is to determine the efficiency of deinkability of irreversible thermochromic prints. Thermochromic inks differ from conventional printing inks in formulation and pigment size due to the presence of microcapsules that are much larger than conventional pigment particles. In order to explain the behavior of these inks in the recycling process, hydrophobicity of the prints will be studies as well

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
Utjecaj adhezijskih svojstava termokromne boje na njezina kolorimetrijska svojstva
Get PDFReverzibilna termokromna (TK) tiskarska boja otisnuta je ofsetnom tehnikom
tiska na četiri različite tiskovne podloge. Prilikom određivanja kolorimetrijskih
svojstava, svaki uzorak je zagrijavan od 35 oC do 75oC i tada ponovno hlađen do
20oC. Kako boja TK otiska ovisi o temperaturi, što ima za posljedicu histerezu
boje, uočeno je da na histerezu boje utječe i tiskovna podloga. Kako bi se
objasnio utjecaj podloge na kolorimetrijska svojstva, određeni su adhezijski
parametri boje na papirima. Međupovršinska napetost, termodinamički rad
adhezije te močenje mogu dati bolji uvid u ponašanje termokromne boje ovisno

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
