Lapposmittia succinea Magoga & Montagna & Marziali & Rossaro & Disaa 2017, comb. nov.
No full textLapposmittia succinea (Goetghebuer, 1942), comb. nov. (Figs 13–19) Orthocladius succineus Goetghebuer, 1942: 664. Type material examined. Orthocladius succineus: LECTOTYPE and PARALECTOTYPE (here designated): two ♁♁, in isinglass, now mounted on the same slide, labelled: ‘ Orthocladius succineus Goetgh. // Lectotype // Paralectotype // Allemagne 1941 dr. Thienemann // R.I.SC.N.B. 18.073 / Coll. et det. M. Goetghebuer’. The labels “ Lectotype ” and “ Paralectotype ” are added on the slide near the respective specimens, an Indian ink line separates the two specimens. Comments. GOETGHEBUER (1942) wrote in his original publication, in a footnote on page 664: ‘came from the Grossen Plöner See, more precise data on the collecting locality and time cannot be given’. ASHE & O’CONNOR (2012) listed Orthocladius succineus among nomina dubia in Orthocladiinae. The specimens are in very poor condition, but the observable characters allow to conclude that the species fits reasonably well in Lapposmittia because of bare wings, eyes and squama, well visible pulvilli, a transparent triangular anal point, well developed virga, a sternapodeme with oral projections, inferior volsella with a rectangular dorsal lobe, and a gently curved gonostylus without crista dorsalis. The generic diagnosis must be emended, because the costa is moderately extended, the antennal plume is not reduced, and the sternapodeme has only moderately developed anterior projections.Published as part of Magoga, Giulia, Montagna, Matteo, Marziali, Laura, Rossaro, Bruno & Disaa, 2017, Revision of type and non-type material assigned to the genus Orthocladius by Goetghebuer (1940 - 1950), deposited in the Royal Belgian Institute of Natural Sciences (Diptera: Chironomidae), pp. 723-749 in Acta Entomologica Musei Nationalis Pragae (Acta.

Parachaetocladius retezati Albu, 1972: 19, syn. nov. Type material examined. Orthocladius collarti: LECTOTYPE (present designation): pinned♁, now mounted on slide, labelled:‘ Orth.collarti n.sp. ♁ D. M.Goetghebuer det.// Lectotype // type locality:Hockai Hautes Fagnes 21.IV.1939 // R.I.SC.N.B.18.073 en grand nombre (éclosion) près du sol, dans un endroit très marecageux’. PARALECTOTYPES: two pinned ♁♁ without hypopygium, now mounted on the same slide, labelled: ‘ Orthocladius collarti // Paralectotypes // same locality. R. Mus. Hist. Nat. Belg. I.G. 12.190 Coll. et det. M. Goetghebuer’. Comments. Orthocladius collarti was listed among nomina dubia in Chaetocladius by ASHE & O’CONNOR (2012). The species is now assigned to Georthocladius Strenzke, 1941 because of the presence of a squama with setae, sinuate Cu1, presence of acrostichals, well developed pulvilli, tarsal pseudospurs present on ta1 and ta2 of p3, a strong triangular anal point with numerous setae, a stout digitiform inferior volsella, and of a gonostylus that is distally enlarged, with a pronounced outer corner. A strong seta at the apex of the antenna seems to be present, but broken in the examined sample. The male hypopygium is identical with the one of Parachaetocladius retezati Albu, 1972; the presence of acrostichals reported in ALBU (1972) also supports inclusion in Georthocladius. We therefore consider P. retezati as a junior synonym of G. collarti.Published as part of Magoga, Giulia, Montagna, Matteo, Marziali, Laura, Rossaro, Bruno & Disaa, 2017, Revision of type and non-type material assigned to the genus Orthocladius by Goetghebuer (1940 - 1950), deposited in the Royal Belgian Institute of Natural Sciences (Diptera: Chironomidae), pp. 723-749 in Acta Entomologica Musei Nationalis Pragae (Acta.

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

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
