Capitula heterogamous; pistillate marginal flowers few, inconspicuous, 5-lobed; disk flowers 3.5–4.5 mm, tubular, deep yellow, 5-lobed, lobes ±glandular, glands hyaline. Anthers exerted, yellowish; style bifid, divergent. Achenes 4–4.5 mm long, 14-ribbed, ±straight; corona ca. 0.3 mm long, denticulate. Additional specimens examined (paratypes): — IRAN. Prov. Kurdistan, West of Sunandaj, Abidar Mountain, 2000 m, 20 June 2003, H. Maroofi 5953 (HKS); same locality, 1700–1800 m, 24 May 2018, H. Maroofi & A. Hesami 13995 (HKS); same locality, 1650 m, 10 June 2018, H. Maroofi 14088 (HKS); same locality, 1800 m, 16 May 2021, H. Maroofi & A. Rastegar 14432 (HKS). Distribution and habitat: — Tanacetum kurdistanicum is restricted to Abidar Mountain, a subalpine region in Kurdistan. It grows on dry northern slopes between 1650 and 2000 m a.s.l. Phytogeographically, it is an Irano-Turanian element. Taxonomic notes: — Tanacetum kurdistanicum has no close relatives based on our comparisons with descriptions in Flora Iranica, Flora of Iran (in Persian), neighboring floras and recently published species accounts. Conservation status: —Based on our field observations during the last 15 years, we observed Tanacetum kurdistanicum at a few localities on Abidar Mountain. Each population counted fewer than 100 individuals. The total area of its range was about 3 km 2. Our annual monitoring revealed degradation in population size and reproduction structure. Based on the IUCN criteria and categories, we assess T. kurdistanicum to be Critically Endangered (IUCN 2022). Phenology: —Flowering April to May, fruiting July to September. Etymology:—The species epithet was derived from Kurdistan, the province where the new species was found.Published as part of Rastegar, Azad, Maroofi, Hosein & Tabad, Mohammad Aref, 2022, Two new species of Tanacetum (Anthemideae, Asteraceae) from western Iran, pp. 111 in Phytotaxa 561 (1) on page 111, DOI: 10.11646/phytotaxa.561.1.11, http://zenodo.org/record/705272

Receptacle convex; marginal flowers about 20, white, 7–12 mm long, 2.5–5 mm wide, apex 3- crenate; disk flowers greenish yellow, lobes brownish, narrowly tubular, ca. 2.5 mm long. Achenes immature, ca. 3 mm long; corona ca. 1.7 mm long, laciniate to base. Additional specimens examined (paratypes): — IRAN. Prov. W Azerbaijan: NW of Urmia, Dalanpar Mountain, Lat 37.176980° N, Lon 44.813662° E, 2950 m, 28 August 2018, M.A. Tabad 13978 (HKS); Prov. W Azerbaijan: NW of Urmia, Boz-e-Sina Mountain, Lat 37.151344° N, Lon 44.791709° E, 3000 m, 24 September 2021, M.A. Tabad 14433 (HKS). Distribution and habitat: — Tanacetum urmiense occurs in alpine zones close to the borders of Iraq and Turkey. It grows on humid northern slopes between 2800 and 3100 m a.s.l. Phytogeographically it is an Irano-Turanian element. Taxonomic notes: — Tanacetum urmiense is closely related to T. hololeucum but differs in the following characteristics: plant height (5–12 cm vs. 10–18 cm); indumentum (glabrous or sparsely pubescent vs. densely appressed tomentose); basal leaves dimensions (35 × 12 mm vs. 15–80 × 10–25 mm); capitula diameter (10–20 × 20–30 mm vs. 8–10 × 6–7), and indumentum of the phyllaries (glabrous or sparsely pubescent vs. sparsely or densely hirsutulose). Conservation status: — Tanacetum urmiense was collected only on Dalanpar and Boz-e-Sina mountains. Fewer than 200 individuals were on each mountain. The total area of distribution was about 6 km 2. Based on the IUCN criteria and categories, we assess T. urmiense to be Critically Endangered (IUCN 2022). Phenology: —Flowering July to September, fruiting September to October. Etymology: —The species epithet was derived from Urmia, a city close to the mountains where Tanacetum urmiense was collected.Published as part of Rastegar, Azad, Maroofi, Hosein & Tabad, Mohammad Aref, 2022, Two new species of Tanacetum (Anthemideae, Asteraceae) from western Iran, pp. 111 in Phytotaxa 561 (1) on page 111, DOI: 10.11646/phytotaxa.561.1.11, http://zenodo.org/record/705272
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
