No full textAloestrela Molteno & Gideon F.Sm., gen. nov. Photographer unknown. ©The National Herbarium of South Africa (PRE), South African National Biodiversity Institute, Pretoria. Reproduced with the permission of the Curator. Type: Aloestrela suzannae (Decary) Molteno & Gideon F.Sm. (≡ Aloe suzannae Decary). Number of species: one. Diagnosis: Solitary, very large, tall-growing, single-stemmed, aloe-like perennial, reaching a height of 4m. Leaves erect to gracefully curved upwards, glaucous-green (Figure 4); surface rough to the touch, margins dentate; apices blunt-rounded. Inflorescence araceme, to 3m tall. Flowers tubular, perigone apices recurved. Description: Perennial, solitary, very large, single-stemmed, leaf succulent. Stem to 3–4(– 7?)m tall, up to 25cm in diameter, brown, rough, usually unbranched, less frequently branched. Leaves 100 × 8–10cm, amplexicaul, succulent, nu-merous, erect to gracefully curved upwards, cymbiform in cross-section, remains of old leaves persistent for a short time; surface dull glaucous green, roughened, lacking spots and scattered teeth, leathery; margins armed with small, triangular teeth; apices blunt- to obtuse-rounded, small-toothed. Inflorescence asimple, erect, densely flowered, cylindrical, brush-like raceme, to 3m tall including peduncle; peduncle to 1m long; pedicels to 30mm long; bracts to 15mm long, not exceeding pedicels, ± elongated-deltoid. Flowers 30–40(–45)mm long, with aslight basal swelling, nocturnal; tepals spreading to strongly recurved apically, white to creamy white, orangey pink-infused; anthers well-exserted, spreading fan-like beyond mouth of flower; filaments pinkish orange; ovary cylindrical; ovules placed almost horizontally, 24–30 per locule (Steyn & Smith, 1998: 195). Fruit a loculicidal capsule. Seed shortly winged. Chromosome number: 2 n = 14 (Brandham, 1971: 387). Genome size (2 C /pg) 33.3 picograms (Zonneveld, 2002: 8). . Distribution: Toliara Province (formerly Toliary or Tuléar), aformer province of Madagascar (endemic). Conservation: The species is of conservation concern (Smith & Swartz, 1997, 1999; Castillon & Castillon, 2010: 274) and is regarded as Critically Endangered (Rakotoarisoa et al., 2014: 89). Etymology:The genus Aloestrela is named for Professor Dr Estrela Figueiredo of the Department of Botany of the Nelson Mandela University in Port Elizabeth, South Africa (Figure 1). Estrela has a longstanding interest in succulent plants and authored or co-authored over 100 scientific papers and several books on aloes alone. The specific epithet suzannae commemorates Mademoiselle Suzanne Decary, daughter of Raymond Decary. Decary first described the species as an aloe (Decary, 1921: 26, foot note no. 2).Published as part of Smith, Gideon F. & Molteno, Steven, 2019, Aloestrela Molteno & Gideon F. Sm.

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
Aloestrela suzannae Molteno & Gideon F. Sm. 2019, comb. nov.
No full textAloestrela suzannae (Decary) Molteno & Gideon F.Sm., comb. nov. ≡ Aloe suzannae Decary in Bull. Econ. Madag. 18 (1): 26 (1921). Type: MADAGASCAR. Ambovombe, 21 July [1923] 1924, [R.] Decary 2913, MNHN-P-P00413803 (neo-), here designated. Note on the type of the name Aloe suzannae, basionym of Aloestrela suzannae:The name Aloe suzannae was published on page 26 of Decary (1921). There is no citation of specimens in the protologueof thename, only mention of localities, as follows: “sud d’Ambaro [south of Ambaro], nord est du Faux Cap [northeast of Faux Cap], Anta-ramaitsy, suddu cirquede Malaimpioky[south of the ‘circus’; in ageological sense it means ahalfopen, steep-sided hollow at the head of avalley or on a mountainside, formed by glacial erosion]”. Further, on page 10 of the text of Decary (1926), before starting his notes on plants, he states that he had an opportunity to record some observati-ons on a certain number of plants of the Tsihombe district, which he presented in the text that follo-wed [“Il m’a été donné de faire sur un certain nom-bre de plantes du district de Tsihombe quelques observations que je donne ci-après”.] Seven of the Decary specimens of Aloe suzannae that are held at Herb. P are databased. In one case the specimen does not have a collector’s num-ber, i.e., it is to be cited as Decary s.n.; the six other specimens are numbered. The six numbered specimens and the unnumbered one resolve as fol-lows, with an indication of the type-status labels that have been affixed to them: Decary 2913; MNHN-P-P00413800; 21 Juillet 1924; purple-stamped “ Ambovombe ”; red-labelled “ ISOTYPE ”. Decary 2913; MNHN-P-P00413801; 21 July 1924; specimen databased, but no image available online at P; “Verbatim locality Ambovombe ”. Decary 2913; MNHN-P-P00413802; 21 Juillet 1924 [“donné par M. Henri Perrier de la Bâthie en 1932”; purple-stamped “ Ambovombe ”; red-labelled “ ISOTYPE ”. Decary 2913; MNHN-P-P00413803; 21 Juillet 192 3;“ Ambovombe ” written by hand in black ink; red-labelled “ TYPE ”. This specimen was also seen by G.W. Reynolds, well-known student of Aloe,as he placed his signature on the specimen, and dated his signature to “ 18/8/55 ”. Decary 3450; MNHN-P-P00413806; 23 November 1924 [“Reçu le”, i.e., “Received on”, presumably at Herb. P] 1 octobre 1925; “ Ambovombe ” written by hand in black ink; Decary 9283; MNHN-P-P00413805; 2 October 1931, [“Reçu le”, i.e., “Received on”, presumably at Herb. P] 20 Mai 1932; red-stamped “ Ambovombe ”; envelope with fragments. Decary s.n.; MNHN-P-P00413804; no collecting date [“Reçu le”, i.e., “Received on”, presumably at Herb. P] 12 Novembre 1921; no locality given; envelope with fragments. Note that six of the seven specimens enumerated above unambiguously have collecting dates that postdate the publication of the name Aloe suzannae,so they cannot be regarded as the holo-type /isotypes. Furthermore, the seventh specimen, Decary s.n., does not have acollecting date (nor a collecting locality, for that matter), with only adate on which it was received, presumably at Herb. P. Since the collecting date of Decary s.n. (and the locality from which it was collected) are unknown, and because it consists of only an envelope with fragments, we did not consider this specimen as aviable option for typification purposes. In addition, since Decary (1926) did not mention any specimens in the protologue of the name A. suzannae, this name clearly does not have a holotype. We here neotypify the name Aloe suzannae, basionym of Aloestrela suzannae,with R. Decary 2913, MNHN-P-P00413803, the only one of the seven specimens listed above that is dated 21 July 192 3.However, the date (July 1923) is considered to be amistake as other collections of Decary that fall in the 2900s range were made in 1924. For example, Decary 2985, P P00508553, dates from 20 July 1924. The other three Decary 2913 specimens (1 to 3, above) are all dated 21 July 1924, and therefore isoneotypes, i.e., duplicates of the neotype designated here.Published as part of Smith, Gideon F. & Molteno, Steven, 2019, Aloestrela Molteno & Gideon F.

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
