Stygiiulus seewaldi Vagalinski & Borissov & Bobeva & Canciani & Antić 2022, comb. nov.
No full textStygiiulus seewaldi (Strasser, 1967) comb. nov. Figs 10E, 13 Alpityphlus seewaldi Strasser, 1967: 146–150, figs 4–9. Typhloiulus seewaldi – Fritsch 1998: 149–150, 16. — Vagalinski et al. 2015: 346. Diagnosis A species of Stygiiulus stat. nov. with normal mouthparts. Easily distinguishable from congeners by its specific gonopod conformation (Fig. 10E) including a narrow, pointed velum considerably exceeding the solenomere and bearing a small, pointed, distal outgrowth (do) (the latter structure present also in S. insularis comb. nov. and in (some specimens of) S. tobias comb. nov.), in combination with the complete absence of a posterior hump on the opisthomere. Also outstanding by the small and rounded internal lobe of the promere, which is positioned close to promeral base. Distribution Germany, Upper Bavaria, Berchtesgadener Land, Untersberg Massif, Cave Hollerloch (the type locality); Austria, Dachstein Mts, tunnel Warmwasserstollen near Lake Hallstatt and Obere Brangrabenhöhle Cave (Fritsch 1998) (Fig. 13, orange squares). Remark Fritsch (1998) listed this species under the genus Typhloiulus, relying on J.-P. Mauriès’ opinion expressed in a letter to him. According to Mauriès who studied material of seewaldi, the erection of the genus Alpityphlus by Strasser (1967) was unfounded, the species being a member of Stygiiulus, at that time a subgenus of Typhloiulus. A similar view was expressed by Antić et al. (2017, 2018), but without a formal transfer to Stygiiulus. Based on the detailed original drawings we fully agree on that view, hence the new name combination is formalized here.Published as part of Vagalinski, Boyan, Borissov, Simeon, Bobeva, Aneliya, Canciani, Giacomo & Antić, Dragan Ž., 2022, The mostly cavernicolous millipede genus Stygiiulus Verhoeff, 1929, stat. nov.: taxonomy, distribution and phylogenetic relationships (Diplopoda, Julida, Julidae), pp. 30-69 in European Journal of Taxonomy 798 on pages 53-55, DOI: 10.5852/ejt.2022.798.1669, http://zenodo.org/record/632300
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Growth and distribution in an AK-model with endogenous impatience
Get PDFThis paper combines two strands of the literature on inequality and distribution issues: the classical approach, which insists on the division of society into classes characterized by different saving propensities, and the social conflict approach, which considers that inequality inflicts direct and indirect costs to economic development. An endogenous-growth model is studied. We assume that each consumer's subjective discount factor is determined endogenously and depends on economic inequality through the following two channels. On the one hand, it is positively related to the individual consumer's relative wealth. On the other hand, it is negatively affected by a simple aggregate measure of social conflict. We show that, unlike models with exogenously given discount rates, steady state equilibria in our model is indeterminate and that the set of all equilibria is acontinuum which can be parameterized by a simple index of income inequality. The growth rate is ambiguously related to the inequality index. However, under some reasonable assumptions, the growth rate dependence on this index has an inverted U-shaped form.wealth distribution, intertemporal choice, growth, development
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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

Distinguishable from congeners by the combination of certain gonopodal characters (Fig. 10D), viz., a mostly straight pro- and mesomere, and an opisthomere with a faint and blunt posterior hump, a marginally broad (not tapering) and deeply serrated velum, and a solenomere with both the anterior and the posterior solenomeral branch being well developed and clearly discernible.</p> Distribution <p> This species has the widest distribution of all representatives of the genus <i>Stygiiulus</i> stat. nov.

Just two/three years later, Verhoeff (1930) described another blind julid, <i>S. maximus</i> comb. nov., from a cave in the same area. What is evident from the gonopod drawings of both Attems and Verhoeff alone – that is that Attems’ (1927) record actually refers to <i>S. maximus</i> comb. nov. – was already confirmed by Strasser (1962: 60) based on re-examination of the specimens from Monte Cavallo.</p>Published as part of <i>Vagalinski, Boyan, Borissov, Simeon, Bobeva, Aneliya, Canciani, Giacomo & Antić, Dragan Ž., 2022, The mostly cavernicolous millipede genus Stygiiulus Verhoeff, 1929, stat. nov.: taxonomy, distribution and phylogenetic relationships (Diplopoda, Julida, Julidae), pp. 30-69 in European Journal of Taxonomy 798</i> on page 48, DOI: 10.5852/ejt.2022.798.1669, <a href="http://zenodo.org/record/6323002">http://zenodo.org/record/6323002</a>
