No full textSyzygium namborense D. Dey, N. Devi & J. Sarma, sp. nov. (Figures 1–4; Table 1). Type:— INDIA. Assam: Golaghat district, Nambor Reserve Forest, Murphulani, 72m, 27 April 2019, 26 ° 22’36.53” N, 93 ° 46’55.49” E, D. Dey DDS2401 (holotype ASSAM!, isotype GUBH!). Syzygium namborense resembles S yzygium nervosum in having glabrous, chartaceous and aromatic leaves, paniculate inflorescence with second order branching, calyptrate flowers, numerous stamens and equal number of petals in the calyptra but differs in having more compressed branchlets with internodes 1.5–2 cm (versus internodes 6–7.7 cm in S.nervosum) and with up to 20 leaves (vs. up to 8 leaves), blades with acumen up to 0.6 cm (vs. up to 1 cm), strictly elliptic leaves with acuminate apex and cuneate base, greater number of lateral veins, intramarginal vein uniform along the blade, sessile yellowish white flowers with obconical hypanthium (vs. greenish white flowers with campanulate hypanthium and pedicel to 2 cm) and 20–30 ovules per locule (vs. 12–15 ovules per locule). Tree 8–15 m tall, 45–52 cm in diameter at body height. Bark coarse, olive green outside eventually turning into black, pale white inside. Branchlets terete, compressed, each with up to 20 leaves at a time, old branchlets greyish white, dry, young branchlets green, fleshy. Nodes thick, slightly angular, 1.5–2 cm apart. Leaves with petioles 1.2–2.5 cm long, the blades simple, opposite and decussate, chartaceous, glabrous, elliptic, 5–18 × 1.1–6.5 cm, cuneate at base, entire to slightly repand at margins, acuminate at apex, pellucid punctuate on both the surfaces, midrib sulcate above, raised below, secondary nerves 13–15 at each side, prominent beneath, forming intramarginal loops near the margin, acumen ca. 0.6 cm long. Inflorescences panicles, usually on leafless old twigs, axillary, 54–65-flowered, main axis 5–7 cm long, bracts minute, 0.1–0.2 cm long, caducous. Flowers yellowish white, 1–1.2 cm long, sessile, calyptrate, the calyptra 0.2 × 0.2 cm, rhombic, often persistent; hypanthium pellucid punctuate, obconical, slightly tapering towards the base, 0.4–0.5 × 0.3–0.5 cm; sepals 4, free, succulent, deciduous, deltate-prolate, rarely attached to the calyptra; petals 4, unified into a calyptra, each 0.1–0.2 cm long, orange brown at the center, white at the periphery with thin longitudinal grooves, irregularly elliptic, pellucid punctate, shortly clawed; stamens white, 60–80 per flower, 0.2–0.5 cm long, filaments slender, anther sacs parallel, dorsifixed, dehiscing by longitudinal slits; style 0.45 cm long, slightly bent; stigma falcate; ovary with axillary placentation; o vules 20–30 per locule. Fruits not seen. Distribution, habitat and ecology:—So far, Syzygium namborense is known only from the tropical semi-evergreen forests of Murphulani, Nambor Reserve Forest, Golaghat district and moist deciduous forests of Donkamukam, Rongkhang Reserve Forest, West Karbi Anglong district of Assam (Figure. 4). It generally grows on open areas of forest edge mostly at the base of hilltops between 71–77 m elev. During the entire survey, only two populations of the species were recorded in Assam. The first population was recorded from Nambor RF consisting of 1 matured individual while the second population was recorded from Rongkhang RF consisting of 5 individuals. Both locations are severely affected by various anthropogenic factors like logging and human settlements. The other associated plants located in the type locality (Nambor RF) were Carallia brachiata (Loureiro 1790: 296) Merrill (1919: 249), Gynocardia odorata R. Brown (1820: 95), Mangifera indica Linnaeus (1753: 200) and Syzygium cumini (Linnaeus 1753: 471) Skeels (1912: 25), whereas Syzygium nervosum, Clerodendrum glandulosum Lindley (1844: t. 19) and Chromolaena odorata (Linnaeus 1759: 1205) R.M. King & H. Robinson (1970: 204) were located in the other locality (Rongkhang RF). Note:—The leaves and flowers give off a strong fruity aroma and harbor a large number of insects, especially ants. They gather around at every node in large numbers and feed on the oozing sap (Figure 2C). Phenology:—Flowering occurs from April to June. Fruits were not seen. Paratypes:— INDIA.

Etymology:—This new species is named after the type location, Nambor Reserve Forest of Assam. Affinities:— Syzygium namborense has resemblances with Syzygium nervosum with which it is compared in the diagnosis and in Table 1.Published as part of Dey, Debolina, Sarma, Jatindra & Devi, Nilakshee, 2022, Syzygium namborense (Myrtaceae), a new species from Assam, India, pp. 133-140 in Phytotaxa 538 (2) on page 134, DOI: 10.11646/phytotaxa.538.2.5, http://zenodo.org/record/633368
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
Lemon basil (Ocimum africanum Lour.) a new distribution record from North East India with notes on its identity
Get PDFThe odoriferous Citronbasilika, also known as lemon basil, possesses a distinctive lemony sweetness amidst all the Ocimum L. members. While native to India, it has not been formally recognized in India\u27s North Eastern (N.E) region until now. This investigation marks the first documented occurrence of lemon basil specifically O. africanum Lour., in N.E India. This new record has been established through meticulous investigation, comparison, diagnosis, verification using herbarium specimens, and a thorough review of existing literature. The report includes a morphological description, careful scrutiny, identification keys, taxonomic notes, and photographic images of the species. The previously existing confusion regarding its identification alongside O. americanum L. and O. basilicum L. has been clarified. This study aims to facilities the accurate identification of these three Ocimum L. species
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
