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
A Study of the Childhood Writings of Ch`i Chun and Hai-yin Lin
No full textThe research motivation is to study how two significant female writers in the fifties, Ch`i Chun and Hai-Yin Lin, resolved inner female anxiety resulting from conflict and insecurity of mind and body after moving to Taiwan. The aim to explore their childhood writings is to understand how the two female writers examined their own childhood, interpreted hometown, and defined value of women autonomy.
The thesis intends to start from the influence of \ue2patriarchy\ue2 in education and personality in the two writer s\ue2 childhood and further analyze their domestic life in terms of father and daughter, mother and daughter relationship extending from \ue2patriarchy\ue2, followed by how the two female writers expose traditional mothers\ue2 silence by interpreting \ue2patriarchy\ue2 in childhood writings. Another focus is the construction from \ue2home\ue2 to \ue2hometown\ue2: it begins with the family space experienced by females, which quotes the illustration of house space in The Poetic of Space by Gaston Bachelard, the control of patriarchy extension in Surveiller et punir: Naissance de la prison by Michel Foucault, and the exploration of female body geography in Gender, Identity and Place by Linda McDowell to explain the relationship and symbol of body and power in spaces. Last, \ue2cultural geography\ue2 is applied to recreate the two female writers\ue2 identity and a sense of belonging toward \ue2hometown\ue2, interpret their value of \ue2childhood living space\ue2 and \ue2hometown reproduction.\ue2 With words, old Zhejiang and Peiping are reconstructed to render what these spaces mean to female self-identity
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Full text linkWe 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
Proton lifetime from SU(5) unification in extra dimensions
No full textWe provide detailed estimates of the proton lifetime in the context of simple supersymmetric SU(5) grand unified models with an extra compact spatial dimension, described by the orbifold S1/(Z2 × Z2') and by a large compactification scale Mc ≈ 1014÷1016 GeV. We focus on a class of models where the grand unified symmetry is broken by the compactification mechanism and where baryon violation proceeds mainly through gauge vector boson exchange so that the proton lifetime scales as Mc4. We carefully compute Mc from a next-to-leading analysis of gauge coupling unification and we find that Mc can only be predicted up to an overall factor 10±1. The simplest model, where the dominant decay mode is π0e+ and has no flavour suppression, is strongly constrained by existing data, but not totally ruled out. We also analyze models where some of the matter fields are localized in the extra space and proton decay is flavour suppressed. In models associated to anarchy in the neutrino sector the preferred decay channel is K+ and the lifetime can be within the reach of the next generation of experiments
Tibetyrus Yin & Lin 2020, gen. nov.
No full textTibetyrus Yin & Lin, gen. nov. Type species. Tibetyrus formicarius sp. nov. (here designated). Diagnosis. Head with relatively small vertexal and frontal foveae; maxillary palpi elongate and basally pedunculate, length of pedunculate portion successively shorter from palpomeres 2 to 4 (Fig. 1B). Pronotum with punctiform median- and small lateral antebasal foveae, with thin and shallow antebasal sulcus connecting foveae. Elytra short and strongly constricted at base, each with two small basal foveae. Visible tergites 1–4 (IV–VII) subequal at midlength. Legs with very short tarsomeres 1, and elongate tarsomeres 2 and 3. Description. Relatively large-sized for pselaphines, body length 3.5–3.7 mm. Head with frontal rostrum moderately long, relatively narrow, formed largely by slightly prominent antennal tubercles; with setose frontal and vertexal foveae; with 11 antennomeres, clubs formed by three apical antennomeres; lacking postantennal notches at lateral margins; lacking lateral postantennal pits, at position where pits occur there are five short and thickened semi-transparent setae; maxillary palpi with small, subtriangular palpomeres 1, palpomeres 2 pedunculate for basal three-fifths, gradually widening and then narrowing again to apices, palpomeres 3 pedunculate for short distance at bases, widening to and truncate at apices, palpomeres 4 enlarged and elongate, suboval, constricted at bases and broadest at basal two-fifths, apices round, lacking apical palpal cones; gula moderately swollen, gular foveae close in shared transverse opening. Pronotum elongate, broadest at apical third, with disc moderately convex; median antebasal fovea punctiform and nude, lateral antebasal foveae relatively small and setose; lateral procoxal foveae present, lacking paranotal carinae/sulci. Elytra subtrapezoidal, each elytron with two small but distinct setose basal foveae; broad, shallow discal striae extending posteriorly from outer basal fovea to apical four-fifths. Mesoventrite lacking median mesosventral fovea, with large lateral mesosventral foveae deeply forked internally, anterolateral mesosventral foveae absent; with large lateral mesocoxal foveae; single median metaventral fovea large and densely setose, posterior margin of metaventrite with looped notch at middle. Legs noticeably elongate, lacking distinct cuticular features; femora moderately thickened, broadest at middle; pro- and mesotibiae slightly curved medially, metatibiae slightly sinuate, all tibiae narrowed at bases and thickened to apices; tarsomeres 1 very short, tarsomeres 2 and 3 elongate, 2 moderately to slightly shorter than 3; pretarsal claws paired and curved at apices. Abdomen with tergites moderately convex, visible tergites 1–4 (IV–VII) subequal at mid-length, tergites 1–3 (IV–VI) each with transverse basal impression, 1–5 (IV–VIII) lacking mediobasal foveae, and each with pair of small basolateral foveae. Visible sternites 2–5 (IV–VII) each with deep basal sulcus, lacking mediobasal foveae, with two basolateral foveae. Males with modified antennae and metaventrite. Aedeagus with apical half of median lobe strongly asymmetric; parameres reduced and symmetric; dorsal diaphragm opening oval. Comparative notes. Among the Asian genera of Tyrini, Tibetyrus gen. nov. shares only with Megatyrus Hlaváč & Nomura the basally pedunculate maxillary palpi that lack apical cones on palpomeres 4. However, Tibetyrus gen. nov. differs from Megatyrus by numerous characters: 1) area between antennal tubercles much less impressed, not deeply sulcate, 2) much shorter pedunculate portion of maxillary palpomeres 3–4, 3) scapes longer than antennomeres 2–3 combined in male, subequal in length in female, 4) a different shape of the pronotum, 5) strongly reduced elytra and total loss of the hindwings, 6) tergites 1–4 (IV–VII) being subequal at their mid-length, 7) lack of a median carina on tergite 1 (IV), and 8) male sexual characters located on antennal clubs and metaventrite. In contrast, all Megatyrus species possess a deep to moderately deep median sulcus on the frons that separates the antennal tubercles, the pedunculate portions of maxillary palpomeres 3–4 are much longer, the scapes are shorter than the following two antennomeres combined in both sexes, the pronotum is broadest at the middle, the elytra have a very broad base, tergite 1 (IV) is as long as 2–3 (V–VI) combined, and with a median carina extends through the entire tergal length, and the male characters are located on the scapes and legs. Tibetyrus gen. nov. can be otherwise separated from all known Asian genera by the form of the maxillary palpi, together with the other external characters as well as the highly distinctive habitus. Etymology. The new generic name is a combination of ‘Tibet’ and ‘ Tyrus Aubé’ (type genus of Tyrini). The gender is masculine.Published as part of Yin, Zi-Wei & Lin, Ye-Jie, 2020, Tibetyrus gen. nov., a new myrmecophilous Tyrini from Xizang, China (Coleoptera: Staphylinidae: Pselaphinae), pp. 131-137 in Zootaxa 4786 (1) on pages 132-133, DOI: 10.11646/zootaxa.4786.1.10, http://zenodo.org/record/386494
