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
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
Testing Different Methods of Grape Seed Germination
Full text linkV letu 2016 smo ugotavljali vpliv različnih načinov priprave pečk vinske trte pred setvijo na začetek in dinamiko kalitve. Poskus je bil izveden v rastlinjaku na Fakulteti za kmetijstvo in biosistemske vede s pečkami desetih sort v treh ponovitvah (160 pečk v ponovitvi). Pred pripravo pečk na setev so bile pečke stratificirane 160 dni pri 9 °C. Potem so bile vse pečke namočene v vodi (48 ur) in pred sejanjem pripravljene na štiri načine: a) brušenje, b) brušenje in namakanje 2 uri v 30% vodikovem peroksidu (H2O2), c) brušenje in namakanje 2 uri v 15% H2O2 in d) kontrola (samo namakanje v vodi). Setev pečk je bila opravljena 20. 4. 2016 v setvene plošče s sadilnim substratom, ki je bil na vrhu pokrit z vermikulitom. Dinamiko kalitve smo spremljali do 30. 6. 2016. Kalitev pečk se je začela najhitreje pri sorti ˈMuscat letniiˈ(35. dan po sejanju) in najkasneje pri sorti ˈEvitaˈ (44. dan). Kalitev pečk je trajala od 28 do 40 dni. Priprava pečk ni imela vpliva na začetek kalitve in dinamiko kalitve, razen pri sorti ˈZelenecˈ. Večji vpliv na kalitev so imele sorte, saj je skalilo od 7 % (ˈRanfolˈ) do 85,8 % (ˈZelenecˈ 2).The study took place in 2016 and its aim was to analyse the influence of different grape seed treatments, prior to sowing, on the beginning and the dynamics of germination. The experiment was carried out in a greenhouse at the Faculty of Agriculture and Life Sciences and involved treated seeds of ten varieties planted in three replications (160 seeds per replication). The seeds were stratified at 9 °C, for 160 days. They were soaked in water (48 h) before sowing and their treatments involved the following four methods: a) scarification, b) scarification and 2 hour soaking in 30 % H2O2, c) scarification and 2 hour soaking in 15 % H2O2 and d) control (soaking in water). The seeds were planted on 20. 4. 2016 in transplanting trays, filled with sowing substrate and topped with vermiculite. The dynamics of germination was monitored until 30. 6. 2016. The earliest germination was observed in the variety ˈMuscat letniiˈ (35 days after sowing), while the latest occurred in the variety ˈEvitaˈ (44 days). The germination was taking place between 28 and 40 days. The treatments had no effect on the beginning and the dynamics of the grape seed germination. The only exception was the variety ˈZelenecˈ. The genotype (variety) had the highest impact on germination rate which ranged from 7 % (ˈRanfolˈ) to 85,8 % (ˈZelenecˈ 2)

Ampelographic and molecular characterisation of open pollination grapevine (vitis vinifera l.) seedlings
Full text linkV letih od 2015 do 2019 smo na UC za vinogradništvo in vinarstvo Meranovo, Fakultete za kmetijstvo in biosistemske vede, Univerze v Mariboru, proučevali uspešnost naravnega križanja vinske trte. Leta 2015 so bila socvetja maternih sort oprašena s socvetji potencialnih očetnih sort iz obstoječega sortnega materiala v genski banki na ta način, da so mladike s socvetji moške in ženske komponente rasle ena ob drugi. Kalitev pečk in vzgoja sejancev je bila opravljena v rastlinjaku v letu 2016. 92 sejancev desetih maternih sort je bilo analiziranih z 20 izbranimi ampelografskimi OIV deskriptorji in 21 molekulskimi SSR markerji. Večina sejancev je bila morfološko zelo podobna maternim sortam (opisani trije odrasli listi med 8. in 12. nodijem). Ampelografske značilnosti so bile preveč variabilne in premalo informativne v primerjavi z SSR markerji. Vsi sejanci so imeli dolžino vsaj enega alela na vsakem opazovanem lokusu enako dolžini enega alela materne sorte. Večina sejancev (79,3 %) je bila posledica samooplodnje. Samo 2,2 % proučevane populacije je nastala z naravnim križanjem med materno sorto in potencialno očetno sorto. Ostali sejanci (18,5 %) pa so nastali z naravnim križanjem materne sorte z neznanim virom peloda. Največji delež sejancev iz naravnega križanja je bil pri starševskem paru sort ˈMuškat Ottonelˈ in ˈŠentlovrenka\u27.From 2015 to 2019, we studied the incidence of natural cross-pollination of grapevines, at the UC for Viticulture and Enology of the Faculty of Agriculture and Life Sciences, University of Maribor, at Meranovo, NE Slovenia. In 2015, inflorescences of several maternal varieties from the gene bank were exposed to pollen from inflorescences of potential paternal varieties in such a way, that the shoots with inflorescences of male and female components were grown side by side. Germination of seedlings and seedling cultivation were carried out in a greenhouse in 2016. 92 seedlings of ten maternal varieties were analysed by 20 selected ampelographic OIV descriptors and 21 molecular SSR markers. Most of the seedlings were morphologically very similar to the maternal varieties (description was based on three fully developed leaves, between 8th and 12th node). The ampelographic characteristics were too variable and less informative when compared to the SSR markers. All seedlings, at each observed locus, had at least one allele size identical to the size of one allele of the maternal variety. The majority of seedlings (79.3 %) were the result of self-pollination. Only 2.2 % of the studied population was formed by natural crossing between the maternal and the potential paternal variety. The remaining seedlings (18.5 %) were formed by natural crossing involving the maternal variety and unknown pollen sources. The highest proportion of seedlings derived from natural cross-pollination was originating from the parental pair involving \u27Muscat Ottonel\u27 and \u27St. Laurent\u27 varieties
