Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Two new hybrid species of Salvia (S. x karamanensis and S. x doganii) from Turkey: evidence from molecular and morphological studies
No full textCelep, Ferhat/0000-0003-3280-8373Salvia L. is an ideal exemplar to demonstrate prezygotic isolation mechanisms in sympatric populations due to their well-known staminal lever mechanism. Mechanical, phenological, and ethological isolation mechanisms have been reported among sympatric species of Salvia. However, it has been shown that if closely related species are sympatric and flower at the same time, they can potentially hybridize. In this study, we describe two new hybrid species of Salvia (S. x karamanensis Celep & B.T.Drew, and S. x doganii Celep & B.T.Drew) from Turkey based on morphological and molecular evidence. Salvia x karamanensis (S. aucheri Benth. subsp. canescens (Boiss. & Heldr.) Celep, Kahraman & Dogan x S. heldreichiana Boiss. ex Benth.) is known from near Karaman city in the central Mediterranean region of Turkey, and S. x doganii (S. cyanescens Boiss. & Bal. x S. vermifolia Hedge & Hub.-Mor.) occurs near Sivas in central Anatolia, Turkey. Morphological comparisons between the hybrid species and their putative parents are given with notes on the International Union for Conservation of Nature (IUCN) red list categories, biogeography and ecology of the two hybrid species.TUBITAKBIDEB 2219 Postdoctoral Research ProgramTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK); NSF-DEB grant [DEB-1655611]We thank Dr. Ricardo Kriebel (University of WisconsinMadison) for assistance with flower scans, Prof.Dr. Esra Martin (Necmettin Erbakan University) for information about chromosome numbers of S. vermifolia, and the curators of herbaria ADO, ANK, BM, E, G, GAZI, HUB, ISTE, ISTF, K, KNYA, and LE for permitting examination of their Salvia collections.

Seed morphology and its systematic implications for genus Oxytropis DC. (Fabaceae)
No full textWOS: 000367792300007In the present study, seeds of 13 Oxytropis DC. species (including two latest synonyms) classified in subg. Oxytropis (sect. Dolichocarpon, sect. Chrysantha and sect. Eumorpha), subg. Euoxytropis (sect. Orobia) and subg. Phacoxytropis (sect. Protoxytropis, sect. Janthina and sect. Mesogaea) from Turkey were examined using light and scanning electron microscopy to evaluate the taxonomic relevance of macro- and micro-morphological seed characters. As a result of the study, species-specific characters have been determined. Seeds exhibit variation in size, shape, surface sculpturing pattern, hilum position and weight. Seeds ranged from 1.61 to 4.04mm in length and from 1.02 to 2.56mm in width. Five different seed shapes were recognised, as prolonged semielliptic, reniform, prolonged reniform, quadratic and cardiform, with a length to width ratio ranging from 1.02 +/- 0.08 to 1.75 +/- 0.27. Rugulate, rugulate-reticulate and lophate sculpturing patterns were observed in the studied species. According to the results, seed characters, such as the size (length, width and the length/width ratio), the shape, the surface sculpturing and the weight appear to have low taxonomic value in distinguishing subgenera, sections and species.Scientific and Technical Research Council of Turkey (TUBITAK) [TBAG-105 T 180]We thank all the curators of herbaria (AEF, ANK, B, E, EGE, G, GAZI, GB, HUB, LE, VANF) which first author visited for their kind permission to work and The Scientific and Technical Research Council of Turkey (TUBITAK) for financial support (Project No: TBAG-105 T 180).

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
From small-scale studies to an encompassing view: Inhibiting inflammation and clinically relevant enzymes with various extracts of Primula vulgaris using in vitro and in silico techniques
No full textThe genus Primula holds great importance as a source of traditional remedies in various folk medicine systems. In the present study, we investigated the chemical composition and biological properties of different extracts (ethyl acetate, ethanol, ethanol/water, and water) of aerial parts and rhizomes of Primula vulgaris. To determine the chemical profile, the extracts were analyzed using ultrahigh performance liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS) technique and flavonoids were a major group in this profile. The antioxidant capacity was demonstrated by in vitro chemical tests and in general the ethanol/water extract was found to be the most potent. Enzyme inhibition was studied against various enzymes and ethanol and ethanol/water extracts were more active than others. To assess the anti-inflammatory potential of the extracts at the molecular level, human dermal fibroblasts (HDF) were treated with lipopolysaccharide (LPS). In vitro experiments showed that the levels of nuclear factor kappa B (NFKB), receptor for advanced glycation endproducts (RAGE), activator protein-1 (AP-1), interleukin 6 (IL-6), interleukin 17 (IL-17) and tumor necrosis factor (TNF)-alpha were significantly reduced after treatment with the tested extracts. In addition, the extracts showed an inhibitory effect on the enzymes collagenase, elastase, and hyaluronidase, which are involved in the inflammatory process and destabilization of the extracellular matrix (ECM). P. vulgaris has been observed to modulate matrix metalloproteinase (MMP) synthesis by decreasing the concentration of cellular reactive oxygen species (ROS) during LPS-induced inflammation. This study also examined the molecular binding and dynamic behavior of various enzymes and proteins associated with skin and infections using ligands derived from the tested extracts. Simulations with AutoDock Vina V1.1.2 and GROMACS 2023.1 showed that isoquercetin in particular showed superior performance in interactions with hyaluronidase. These findings are important for the development of potential therapeutic strategies for skin health and infection control. In summary, P. vulgaris can be considered as an important source of natural bioactive compounds for the development of effective health-promoting applications in nutraceuticals, pharmaceuticals, and cosmetics
