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
Pollentia Capa & Pons & Jaume 2022, GEN. NOV.

Zoobank registration: urn: lsid: zoobank. org: act: A 0 C C E E 3 2 - 9 4 F E - 4 4 C 7 - B B 1 D - C4DD85D58FB5 Diagnosis: Body flattened dorsoventrally, with ≤ 27 segments (Fig. 4). Prostomium bilobed (Fig. 5A–C). Frontal filaments absent. Eyes absent (Fig. 5A–C). Median and lateral antennae present; lateral antennae inserted subterminally on extensions of prostomium (Fig. 5A–C). Facial tubercle absent. Tentaculophores with acicula and chaetae (Figs 5, 6B). Dorsal tubercles present. Elytrophores large, 13 pairs: one pair on each of segments 2, 4, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23 and 26. Elytra large, covering dorsum, lacking papillae, each with microtubercles along external edge and posterior dorsal surface. Parapodia subbiramous; noto- and neuropodia with elongate acicular lobe. Notochaetae with spinous rows and pointed tips. Neurochaetae numerous, of two types: superior, flattened, with spinous rows and with tridentate tip; and inferior, shorter and thinner, lanceolate and pectinate, with spinous rows and tapering. Nephridial papillae present from segment 5 onwards. Remarks: The erection of a new genus is required to accommodate this taxon because it shows some unique features not reported in any other member of the subfamily Eulagiscinae, namely, the display of 13 pairs of elytra and the morphology and arrangement of noto- and neurochaetae. In addition, Pollentia shows a unique combination of features: eyelessness; tentaculophores bearing acicula and chaetae; nephridial papillae present from segment 5 onwards; only one type of notochaetae present from segment 2 onwards, stout and spinous; and two types of neurochaetae: superior flattened, spinous and tridentate; and inferior smaller, lanceolate and pectinate with spinous rows reaching the tip. Etymology: Generic name refers to Pollentia, an ancient Roman city located in the current Mallorcan municipality of Alcúdia, where the cave harbouring the new taxon is located. Gender feminine. Type species: Pollentia perezi sp. nov., described herein, by monotypy.Published as part of Capa, María, Pons, Joan & Jaume, Damià, 2022, Discovery of a new scale worm (Annelida: Polynoidae) with presumed deep-sea affinities from an anchialine cave in the Balearic Islands (western Mediterranean), pp. 479-502 in Zoological Journal of the Linnean Society 196 on pages 489-490, DOI: 10.1093/zoolinnean/zlac046, http://zenodo.org/record/703546
It is all downhill from here: a typological study of the role of syllable contact in Romance languages
No full textThe purpose of this paper is to explore, on the basis of a quite extensive set of processes drawn from Romance languages, the nature and the effects of the SYLLABLE CONTACT constraint in Optimality Theory. In order to achieve that, we investigate and formalize a) the process of regressive manner assimilation that applies in some varieties of Catalan as well as in Lenguadocian Occitan, 2) the processes of onset strengthening and epenthesis that occur in Catalan, 3) the process of 's' rhotacism that is found in Majorcan Catalan, in some dialects of Sardinian and in some dialects of Galician, among other Romance languages, 4) the process of 's' gliding that arises in Lenguadocian Occitan, and, finally, 5) the selection between epenthesis and deletion in word-initial consonantal clusters violating the minimum sonority distance constraints in Catalan. The analysis of these processes, most of them not considered in the literature devoted to SYLLABLE CONTACT, leads to some important theoretical implications: a) SYLLABLE CONTACT should not be regarded as a single constraint which categorically bans coda-onset clusters with rising sonority, but it should be decomposed into a universal hierarchy of constraints targeting all possible sonority distances between adjacent heterosyllabic segments, as originally suggested by Murray & Vennemann (1983), formalized in OT terms by Bat-El (1996) and Gouskova (2001, 2002, 2004), and applied to Romance languages in Pons (2003b, 2004a, 2005b); b) the sonority scale in Catalan should distinguish flaps and trills, the latter being less sonorous, as previously proposed for Catalan and other Romance languages in Bonet & Mascaró; (1997), Parker (2002), Pons (2004a, 2005b); c) the sonority scale of Catalan should treat separately voiced and voiceless stops, the latter being less sonorous, as traditionally put forward in some studies devoted to syllable structure (see, for instance, Steriade 1982, for Attic Greek; Davis 1990, for Italian; and Blevins 1995).The publisher of the journal in which this article appears does not permit the archiving of this or any other version of the article in the Rutgers Optimality Archive.

VIP-like and GFAP-like immunoreactivities in the chicken brain stem. II. The pons and the tegmentum of the mesencephalon.
No full textAn immunocytochemical analysis was performed on the chicken pons and mesencephalon (except the optic tectum) according to the PAP-DAB procedure, to study the distribution here of the neurons reacting to anti-VIP antibodies and the gliocytes reacting to anti-GFAP antibodies. Positive and negative controls were carried out in both the immunoreactions. The VIP-immunoreactive neurons showed a distribution essentially corresponding to that observed in other species by various Authors. They appeared scattered mainly in 3 sites: (a) the subventricular grey between pons and mesencephalon; (b) the periaqueductal grey, up to the diencephalon; (c) the rostro-ventral portion of the mesencephalic tegmentum, up to the diencephalon. Furthermore, some perivascular VIP-immunoreactive neuronal processes were seen. No differences have so far been detected as regards the GFAP-like immunoreactivity distribution, in comparison with the data reported by the authors in the chicken medulla and by others in in the brain stem of some other species

C-fos expression in the pons and medulla of the cat during carbachol- induced active sleep
No full textMicroinjection of carbachol into the rostral pontine tegmentum of the cat induces a state that is comparable to naturally occurring active (REM, rapid eye movement) sleep. We sought to determine, during this pharmacologically induced behavioral state, which we refer to as active sleep-carbachol, the distribution of activated neuron within the pons and medulla using c-fos immunocytochemistry as a functional marker. Compared with control cats, which were injected with saline, active sleep-carbachol cats exhibited higher numbers of c-fos-expressing neurons in (1) the medial and portions of the lateral reticular formation of the pons and medulla, (2) nuclei in the dorsolateral rostral pons, (3) various raphe nuclei, including the dorsal, central superior, magnus, pallidus, and obscurus, (4) the medial and lateral vestibular, prepositus hypoglossi, and intercalatus nuclei, and (5) the abducens nuclei. On the other hand, the mean number of c-fos-expressing neurons found in the masseter, facial, and hypoglossal nuclei was lower in carbachol-injected than in control cats. The data indicate that c- fos expression can be employed as a marker of state-dependent neuronal activity. The specific sites in which there were greater numbers of c- fos-expressing neurons during active sleep-carbachol are discussed in relation to the state of active sleep, as well as the functional role that these sites play in generating the various physiological patterns of activity that occur during this state.</jats:p
