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

Revision of the Antipatharia (Cnidaria: Anthozoa). Part V. Establishment of a new family, Stylopathidae
No full textA new family of antipatharian corals, Stylopathidae (Cnidaria: Anthozoa: Antipatharia), is established for Arachnopathes columnaris Duchassaing, 1870, and related species. The family is characterized bysmall polyps, 1.5 mm or less in transverse diameter; small, conical, smooth spines, often distally directed(especially at the tips of the branchlets and/or pinnules); and by the tendency for the pinnulesand branchlets to occur in subopposite pairs or to be arranged in verticils of three or four (rarely five)pinnules. In many species adjacent pinnules or branchlets fuse together or anastomose, resulting in theformation of cylindrical, reticulated worm runs along the stem or branches. Genera are established onthe basis of morphological features of the corallum. Stylopathes gen. nov., includes the type species,Arachnopathes columnaris Duchassaing, and is characterized by a monopodial or very sparsely branchedcorallum. Triadopathes gen nov. contains only the type species Parantipathes triadocrada Opresko, and has multiple, vertically directed, stem-like primary branches, arising primarily from the lower parts ofthe corallum. Tylopathes Brook contains the type species T. crispa Brook, and is characterized by a flabellatecorallum with short, mostly bilateral branchlets
Redescription of Antipathes dichotoma Pallas, 1766 (Cnidaria: Anthozoa: Antipatharia)
No full textThe type species of the genus Antipathes, (A. dichotoma Pallas, 1766) is redescribed and a neotype is designated. Differences in the size and shape of the spines, and in the size and density of the polyps are considered key characters in separating related species
Revision of the Antipatharia (Cnidaria: Anthozoa). Part IV.
No full textA new family of antipatharian corals, Aphanipathidae (Cnidaria: Anthozoa: Antipatharia), is established for Aphanipathes sarothamnoides Brook and related species. The family is characterized by tall, conical, acicular or cylindrical spines, which are usually covered to some degree with small tubercles (smooth spines occur in some species), and by polyps that are 0.5-1.3 mm in transverse diameter and have small, subequal tentacles. The family is divided into two subfamilies based on differences in the development of the polypar spines. In the Aphanipathinae the polypar spines are subequal. Genera are recognized on the basis of morphological features of the corallum. Aphanipathes Brook (type species A. sarothamnoides Brook) has a sparsely to densely branched corallum with straight, usually ascending, branchlets. Phanopathes gen. nov. (type species Antipathes expansa Opresko & Cairns) forms fan-shaped colonies with irregularly bilateral branchlets. Pteridopathes gen. nov. (type species P. pinnata spec. nov.) has mostly simple pinnules (sometimes with randomly occurring simple secondary pinnules) arranged in two rows. Tetrapathes gen. nov. (type species Aphanipathes alata Brook) has simple pinnules arranged in four rows, and Asteriopathes gen. nov. (type species A. arachniformis spec. nov.) has simple pinnules arranged in six or more rows. In the Acanthopathinae the polypar spines are anisomorphic, with the circumpolypar spines larger than the interpolypar spines and the hypostomal spines usually reduced or absent. As in the Aphanipathinae, genera are recognized on the basis of morphological features of the corallum. Acanthopathes gen. nov. (type species Antipathes humilis Pourtalès) forms candelabra and flabellate colonies and has reduced hypostomal spines. Rhipidopathes Milne Edwards & Haime (type species Antipathes reticulata Esper), forms flabellate colonies and has hypostomal spines that are not always reduced in size. Distichopathes gen. nov. (type species D. disticha spec. nov.) has simple, straight pinnules arranged primarily in two rows, and Elatopathes gen. nov. (type species Antipathes abietina Pourtalès) has simple pinnules arranged in four or more rows
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
Revision of the Antipatharia (Cnidaria: Anthozoa). Part II. Schizopathidae
No full textThe family of antipatharian corals, Schizopathidae (Cnidaria: Anthozoa: Antipatharia), is revised. The family is characterized by polyps elongated in the direction of the axis and having a transverse diameter of 2 mm or more. Genera are recognized on the basis of morphological features of the corallum. Schizopathes Brook (type species: S. crassa Brook) has a simple, pinnate corallum with a hook-like holdfast for support in soft sediments. Bathypathes Brook (type species: B. patula Brook) is characterized by a simple pinnate corallum and a flat discoidal basal plate for attaching to a solid substrate. Parantipathes Brook (type species: Antipathes larix Esper) has a largely monopodial corallum with simple pinnules in six or more rows. Taxipathes Brook (type species: T. recta Brook) has a branched corallum and simple pinnules in four to eight rows. Lillipathes gen. nov. (type species: Antipathes lilliei Totton) has simple pinnules in four rows. Stauropathes gen. nov. (type species: S. staurocrada spec. nov.) is branched with simple, bilateral, subopposite pinnules. Abyssopathes gen. nov. (type species: Bathypathes lyra Brook) is monopodial with two rows of simple, lateral pinnules and one (sometimes multiple) row of simple or branched anterior pinnules. Dendrobathypathes gen. nov. (type species: D. grandis spec. nov.) has a branched, planar corallum with two rows of subpinnulated primary pinnules. Saropathes gen. nov. (type species: Bathypathes scoparia Totton) is monopodial to sparsely branched, with four rows of subpinnulated primary pinnules

No full textA new species of Allopathes (Cnidaria: Antipatharia) from the eastern Atlantic
No full textA new species of antipatharian coral, Allopathes denhartogi, is described from the eastern Atlantic. The species is distinguished from the two other species in the genus by spines that are larger, less dense and not arranged in verticils. Furthermore, the colony appears to reach a smaller size and has relatively fewer ramifications compared to the other species
