    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The 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

    Dispelling the Myths Behind First-author Citation Counts

    We 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

    Genus Vappolotes Zhao & Li, 2019 Type species. Vappolotes ganlongensis Zhao & Li, 2019, from Guizhou Province. Remarks. The genus Vappolotes originally was described with only two species: V. ganlongensis Zhao & Li, 2019 (♀ ³) and V. jianpingensis Zhao & Li, 2019 (♀). Some diagnostic characters of this genus are amended here, eg. conductor with dorsal and ventral apophyses in Li et al. (2019a) corrected to dorsal conductor and anterior conductor; tegular apophysis in Li et al. (2019a) corrected to posterior conductor; retrolateral tibial apophysis in Li et al. (2019a) corrected to lateral tibial apophysis; ventrolateral tibial apophysis in Li et al. (2019a) corrected to retrolateral tibial apophysis (Fig. 1A–C); atrium with longitudinal setae plexus, copulatory ducts and spermathecae located anteriorly, medially or posteriorly (Fig. 1D, E). Li et al. (2019a) and Okumura & Zhao (2022) proposed Vappolotes, Longicoelotes Wang, 2002, Platocoelotes Wang, 2002, Papiliocoelites Zhao & Li, 2016 and Spiricoelotes Wang, 2022 are sister groups belonging to lacking epigynal teeth clade, as: {[(Vappolotes + Papiliocoelotes) + Spiricoelotes] + Longicoelotes} + Platocoelotes.Published as part of Li, Bing, Zhao, Zhe & Li, Shuqiang, 2023, Three new species of the genus Vappolotes Zhao & Li, 2019 (Araneae, Agelenidae) from southwest China, pp. 325-336 in Zootaxa 5270 (2) on page 326, DOI: 10.11646/zootaxa.5270.2.8, http://zenodo.org/record/786501

    2. Stenus (Hypostenus) yiae Zhao & Zhou, sp. nov. Type Material. Holotype: male, CHINA, Beijing, Chaoyang, Datunxiang (116°24′E, 39°59′N), 21.V. 1996, Hong-zhang Zhou collected [Deposited in Institute of Zoology, Chinese Academy of Sciences (IZ-CAS)]; Paratypes: 1 female, same data as holotype; 1 male, 1 female, CHINA, Beijing (116°28′E, 40°13′N), 1942; 1 male, 2 females, CHINA, Fujian, Shaxian (117°46′E, 26°25′N), 15.VII.1977, Xiao-nan Luo collected; 2 males, 3 females, CHINA, Shanghai (121°29′E, 31°13′N), A. SAVIO collected; 14 ex., CHINA, Shanghai (121°29′E, 31°13′N), O. PIEL collected. [Deposited in Institute of Zoology, Chinese Academy of Sciences (IZ-CAS)] Diagnosis. This new species belongs to the cicindeloides group. It can be easily distinguished from S. (H.) verticalis Benick and S. (H.) primivenatus Zhao & Zhou sp. nov. by the absence of spots on elytra. It is similar to S. (H.) cicindeloides (Schaller), but differs from the latter by having a broad apical part of median lobe and a different spermatheca structure. Detailed description and illustrations of the species are provided by Zhao & Zhou (2008).Published as part of Zhao, Cai-Yun & Zhou, Hong-Zhang, 2020, Validation of Stenus (Hypostenus) primivenatus and Stenus (Hypostenus) yiae (Coleoptera, Staphylinidae, Steninae), pp. 591-592 in Zootaxa 4881 (3) on page 591, DOI: 10.11646/zootaxa.4881.3.11, http://zenodo.org/record/428387

    Nanoimprint lithography for planar chiral photonic meta-materials

    No full text
    Room temperature nanoimprint lithography has successfully been applied to the fabrication of planar chiral photonic meta-materials. For dielectric chiral structures a single layer of thick HSQ was used while for metallic chiral structures a bi-layer technique using PMMA/hydrogen silsequioxane (HSQ) was applied. The polarization conversion capabilities of planar chiral structures imprinted in dielectric materials have experimentally been observed. This indicates that the developed processes in this work have the prospect of manufacturing planar photonic meta media in high volume at low cost

    No full text
    This 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
