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

A narrow endemic known only from the Zagros Mountains, first found around Darab, Rostaq and Bezan passes (Rechinger, 1979) and later in Hormozgan Province, Haji Abad, Shamil-e Bala, Bukhun, by Mozaffarian (Jamzad, 2012).</p> <p> <i>Habitat and ecology</i>. This species occurs on rocky limestone slopes with shallow soil on arid mountains (see <b>Figure 6A,B</b>). The areas of distribution in Darab (Fars) and Bukhun (Hormozgan) are the transitional area between the Irano-Turanian and Saharo-Arabian floristic regions (Zohary, 1973). It typically bears leaves around its base in spring (see <b>Figure 6A</b>), these subsequently dropping due to drought. Therefore it can appear leafless for parts of the year (see <b>Figure 6B</b>).</p> <p> <i>Conservation status</i>. According the AOO of 48 km 2 and EOO of 267 km 2, <i>Lavandula sublepidota</i> is categorised as Endangered (EN) [B1ac(ii+iii+iv) + B2ac(ii+iii+iv) + D] (IUCN, 2012). During recent exploration of the area, only a single individual was recorded at the type locality (see <b>Figure 4</b>).</p> <p> <i>Ethnobotany</i>.

The scale-like adpressed stem hairs, reflected in the epithet, are unique and give the species its characteristic whitish appearance.</p> <p> Rechinger (1979) originally placed the species in sect. <i>Pterostoechas</i> and noted affinities to <i>Lavandula coronopifolia</i> (treated as <i>L. stricta</i>). Although it bears single-flowered cymes, these are spirally arranged in <i>Lavandula sublepidota</i> rather than decussate, as is diagnostic for sect. <i>Pterostoechas</i>. Its sectional affinities therefore lie elsewhere and are discussed further below.</p>Published as part of <i>Bordbar, Firouzeh & Upson, Tim M., 2021, TAXONOMIC REVIEW AND PHYLOGENETIC INVESTIGATIONS OF LAVANDULA FROM IRAN AND OMAN, pp. 1-16 in Edinburgh Journal of Botany 78 (347)</i> on pages 9-11, DOI: 10.24823/EJB.2021.347, <a href="http://zenodo.org/record/10590793">http://zenodo.org/record/10590793</a>
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

Bové</i> 55 (lectotype and isolectotype P [photos!]).</p> <p> <b>Figure 5</b> <b>.</b></p> <p> <i>Description</i>. See Upson & Andrews (2004).</p> <p> <i>Phenology</i>. In Iran, flowers from February to October, curtailed by winter cold rather than drought stress. Inflorescences up to 10 cm long are common, bearing both flowers and fruit (see <b>Figure 5D</b>).</p> <p> <i>Distribution</i>. Southwest Asia (Jordan and Palestine), Northeast Africa (Egypt, Eritrea), the Arabian Peninsula (Saudi Arabia and Republic of Yemen) and Iran (Bushehr Province).</p> <p> <i>Habitat and ecology</i>. This species is found in the moist valleys on the northern slopes of Mount Khormoj and is known from two populations 5 km apart (see <b>Figure 4</b>). Here it is restricted to mesic environments in moist valleys on the northern slopes, which are recognised as part of the Saharo-Arabian floristic region (Zohary, 1973).</p> <p> One population grows on stony margins of date palm gardens and the other on rocky slopes and stony habitats accompanied by <i>Mentha mozaffarianii</i> Jamzad, a narrow endemic species previously recorded only from Hormozgan Province (Jamzad, 1987; see <b>Figure 5A</b>). It is clearly restricted to favourable microclimates away from the intense aridity typical of the area.</p> <p> <i>Conservation status</i>. During field observations, about 30 individuals were counted in two populations with an AOO of about 12 km 2 and an EOO of 0.05 km 2. <i>Lavandula pubescens</i> is assessed as Critically Endangered (CR) in Iran [B1ac(ii+iii_iv)+B2ac(ii+iii+iv) + D] (IUCN, 2012). Its occurrence with the other restricted species strongly suggests that these habitats need protection. Globally, it is of Least Concern (LC) (Upson & Andrews, 2004).</p> <p> <i>Ethnobotany</i>. This species’ essential oil is composed largely of carvacrol, caryophyllene oxide, β-bisabolene, <i>p</i> -cymen-8-ol, β-caryophyllene, carvacrol methyl ether and terpinolene, and has shown notable antibacterial and antifungal activity (Chhetri <i>et al.</i>, 2015; Ibrahim <i>et al.</i>, 2017; Al-Badani <i>et al.</i>, 2017). It has been the subject of many studies for its application in the production of palm oil (Rashed <i>et al.</i>, 2016) and honey (Nuru <i>et al.</i>, 2015). In Yemen it is used in folk medicine as a carminative, insect repellent and antiseptic (Chhetri <i>et al.</i>, 2015). No uses are recorded in Iran, and based on fieldwork it is little known to local people.</p> <p> <i>Specimens examined</i>.

The pinnatisect leaves, which are highly dissected two or three times, are characteristic (see <b>Figure 5B</b>). It is a species of arid areas, as reflected in its woody rootstock and stem base from which annual stems are produced (Collenette, 1985; Upson & Andrews, 2004).</p> <p>Its previously known distribution followed the Syro-African Rift Valley, with the species occurring on mountains and hills along the Red Sea coast and reaching the Dead Sea depression in the north. Its occurrence in Iran is significant due to the large disjunction across the Arabian Peninsula.</p>Published as part of <i>Bordbar, Firouzeh & Upson, Tim M., 2021, TAXONOMIC REVIEW AND PHYLOGENETIC INVESTIGATIONS OF LAVANDULA FROM IRAN AND OMAN, pp. 1-16 in Edinburgh Journal of Botany 78 (347)</i> on pages 8-9, DOI: 10.24823/EJB.2021.347, <a href="http://zenodo.org/record/10590793">http://zenodo.org/record/10590793</a>
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
