No full textZorotypus (Octozoros) hirsutus Mashimo, sp. n. (Figs. 1, 2) Holotype: Alate female; Myanmar, Kachin State, Hukawng Valley (Kania et al. 2015: fig. 1; Jałoszyński et al. 2017: fig. 1); Albian-Cenomanian boundary, mid Cretaceous. The holotype is deposited in Patrick Müller’s private collection (depository number BUB 2785). Etymology. The specific name is taken from a Latin adjective hirsutus meaning “hairy, shaggy”, and refers to the bristly or hirsute appearance, with a dense vestiture of long and slender setae. Diagnosis. Zorotypus hirsutus sp. n. is tentatively assigned to the subgenus Octozoros based on the eightsegmented antenna. This species is readily distinguished from the other species of Octozoros by the combination of the following characters: strongly developed vestiture of bristles on the entire body; very slender, elongate antennomeres; elongated head with concave genal region; absence of thorn-like protuberances on mesonotal anterolateral corners; absence of jugate setae along posterior margin of forewings; relatively slender tibiae; empodium of meta-pretarsus reduced to a slender hair-like structure. Description. Alate female. Integument blackish brown except antennomeres VII and VIII (Fig. 1A, B). Head subtriangular, moderately elongated, with concave genal region (Figs. 1C, 2A). Surface covered with vestiture of long setae (Figs. 1C, 2A). Compound eyes prominent; three ocelli present. Antennae 8-segmented, with vestiture of setae of moderate length (Fig. 1A, B); antennomere I elongate, approximately 4.5 times longer than wide; antennomere II relatively short, about one-third as long as antennomere I; antennomere III elongate, approximately twice as long as antennomere II; antennomeres IV–VI distinctly elongated, slender, approximately six times as long as wide; antennomeres VII-VIII very slender, approximately four times as long as wide. Maxilla only partly visible; galea with comb of mesally directed setae on apical region (Figs. 1C, 2A); slender lacinia with two small mesally directed teeth on distal part (Fig. 2A); maxillary palpus with palpomere I not visible; palpomeres II, III and V distinctly elongated; palpomere IV slightly longer than wide. Labial palpus with palpomere I partly visible; palpomere II slightly elongated and palpomere III distinctly elongated (Figs. 1C, 2A). Pronotum subrectangular, longer than wide, slightly narrowing anteriorly; with vestiture of setae of moderate length on surface and also densely covered with long setae along margins (Fig. 1D). Mesonotum only partly visible; distinctly broader than long, about half as long as pronotum; thorn-like protuberances on the anterolateral corners absent; with vestiture of setae of moderate length on surface and along margins. Metanotum (and part of wings) covered by bubble; distinctly broader than long, slightly shorter than mesonotum, with setae of moderate length along lateral and posterior margin. Legs densely covered with setae of moderate length; tarsi 2-segmented. Protibia with bristles arranged as comb along distal ventral half and pair of spurs inserted apically (Fig. 1C, E). Mesotibia with apical pair of spurs (Fig. 1F). Metafemur proximally expanded, gently tapering towards apex; eight stout spines (sp1–8) placed on tubercles along posterior border of ventral surface (1–7 in Fig. 1F); sp5 and sp7 distinctly elongated; sp1 slightly longer than remaining spines (Fig. 1E); right metafemur with one additional small spine between sp6 and sp7 (6+ in the inset in Fig. 1F); three stiff bristles inserted at preapical region of anterior border of ventral surface (Fig. 1F). Metatibia slender, with two stout spines at apical one-third and at apex (a, b in Fig. 1A), additionally with tiny spine near most apical spine (white arrow in Fig. 1A, G). Meta-pretarsus with pair of small pulvilli (black arrowhead in the inset in Fig. 1G); empodium reduced to slender hair-like structure (white arrowhead in the inset in Fig. 1G). Stiff spine present between metacoxae (black arrow in Fig. 1F). Abdominal setae dense (Fig. 2C). Abdominal tergum I (T1) with transverse row of setae of moderate length along posterior margin (Fig. 2B); T2–10 with vestiture of setae of moderate length; T2–7 with pair of long, erect setae on both sides of posterior region; T8–9 with two pairs of long, erect setae on both sides of posterior region. Median up-curved projections missing (Fig. 2C). Cercus unsegmented, conical, with four or five long subapical setae almost as long as cercus, proximally with moderate to long, fine setae (Figs. 1A, B, 2B, C). Abdominal sterna I–III (S1–3) not visible; S4–8 with setae of moderate length (Fig. 2C). Wing venation (Fig. 1A, B) visible as faint, fuscous lines; membrane hyaline except for brownish pterostigma of forewing, covered with minute setae; both fore and hind wings with dense fringes of short setae, slightly longer than those of membrane; posterior margin of forewings lacking stiff, jugate setae.

A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Dissipative Range Scaling of Higher Order Structure Functions for Velocity and Passive Scalars
No full textDifferently to Kolmogorov's second similarity hypothesis, we find that the 2n-th order velocity and scalar structure functions scale with n-th order moment of the energy dissipation and the scalar dissipation, respectively. The origins of this scaling are analyzed by the transport equations of the fourth order velocity and scalar increment moments and by direct numerical simulations
