Known distribution. Porto Paone, Gulf of Naples, Italy (Boaden 1965). Archipel de Riou, Provence-Alpes-Côte d’Azur, France (Brunet 1968). Remarks. Our observations correspond to those of earlier authors (Boaden 1965; Brunet 1968). Live specimens measure up to 1.8 mm and have a slightly reddish pigmentation. The mouth is situated a short distance behind the proboscis. The proboscis is armed with a pair of slender hooks (15–16 μm) and bears a pair of thin, non-sclerotised sidepieces (12–13 μm). A single subterminal haptic girdle is present near the caudal body end. A single testis is present near the posterior end of the pharynx. From the testes, a pair of vasa deferentia leads to the paired seminal vesicles. Each seminal vesicle is 120–150 μm long. The seminal vesicles enter the proximal end of the male copulatory apparatus. The copulatory bulb contains a prostatic vesicle, 70–80 μm long, followed distally by a relatively short ejaculatory duct. The distal part of the ejaculatory duct is sclerotised to form an unarmed, tubular cirrus. Distally, the cirrus is provided with a number of fine, sclerotised ridges. According to Boaden (1965), only this part of the cirrus is eversible. A strongly muscular vagina externa is present in the posterior part of the body. It consists of a thin-walled canal, leading from the vaginal opening (shortly behind the common genital pore), to a thick-walled proximal section, which is divided into three chambers. Conspicuous radial striations are present on the vaginal wall in this part. Proximally, the vagina opens into a thin-walled bursa, which lies adjacent to the single ovary.Published as part of Gobert, Stefan, Diez, Yander L., Monnens, Marlies, Reygel, Patrick, Van Steenkiste, Niels W.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Sipari gotici. Lo strano caso del Dr. Boaden e Mr. Lewis
No full textStarting from the remarkable intellectual bond linking James Boaden and Matthew
Gregory Lewis, this paper investigates the nature of the relationship that, at the end
of the eighteenth century, came to be established between the theatrical adaptations
of the most popular Gothic novels and Gothic “original” plays. The fact that most authors
adapting Gothic novels for the theatre make a show of constructing a “gothicising”
kind of drama, conveying a certain cultural and social respectability, is interpreted
here as a deliberate attempt at defusing a genre, both narrative and theatrical, that was
perceived as subversive and anti-nationalistic. In this effort towards normalization, one
can see the reflections of a question of identity that runs through the society of the time
and that goes beyond the field of literature, even while involving it
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
Antidepressants in children and adolescents: meta-review of efficacy, tolerability and suicidality in acute treatment
No full textAntidepressants are prescribed for the treatment of a number of psychiatric disorders in children and adolescents, however there is still controversy about whether they should be used in this population. This meta-review aimed to assess the effects of antidepressants for the acute treatment of attention-deficit/hyperactivity disorder (ADHD), anxiety disorders (ADs), autistic spectrum disorder (ASD), enuresis, major depressive disorder (MDD), obsessive-compulsive disorder (OCD), and posttraumatic stress disorder (PTSD) in children and adolescents. Efficacy was measured as response to treatment (either as mean overall change in symptoms or as a dichotomous outcome) and tolerability was measured as the proportion of patients discontinuing treatment due to adverse events. Suicidality was measured as suicidal ideation, behavior (including suicide attempts) and completed suicide. PubMed, EMBASE, and Web of Science were systematically searched (until 31 October 2019) for existing systematic reviews and/or meta-analyses of double-blind randomized controlled trials. The quality of the included reviews was appraised using AMSTAR-2. Our meta-review included nine systematic reviews/meta-analyses (2 on ADHD; 1 on AD; 2 on ASD; 1 on enuresis; 1 on MDD, 1 on OCD and 1 on PTSD). In terms of efficacy this review found that, compared to placebo: fluoxetine was more efficacious in the treatment of MDD, fluvoxamine and paroxetine were better in the treatment of AD; fluoxetine and sertraline were more efficacious in the treatment of OCD; bupropion and desipramine improved clinician and teacher-rated ADHD symptoms; clomipramine and tianeptine were superior on some of the core symptoms of ASD; and no antidepressant was more efficacious for PTSD and enuresis. With regard to tolerability: imipramine, venlafaxine, and duloxetine were less well tolerated in MDD; no differences were found for any of the antidepressants in the treatment of anxiety disorders (ADs), ADHD, and PTSD; tianeptine and citalopram, but not clomipramine, were less well tolerated in children and adolescents with ASD. For suicidal behavior/ideation, venlafaxine (in MDD) and paroxetine (in AD) were associated with a significantly increased risk; by contrast, sertraline (in AD) was associated with a reduced risk. The majority of included systematic reviews/meta-analyses were rated as being of high or moderate in quality by the AMSTAR-2 critical appraisal tool (one and five, respectively). One included study was of low quality and two were of critically low quality. Compared to placebo, selected antidepressants can be efficacious in the acute treatment of some common psychiatric disorders, although statistically significant differences do not always translate into clinically significant results. Little information was available about tolerability of antidepressants in RCTs of OCD and in the treatment of ADHD, ASD, MDD, and PTSD. There is a paucity of data on suicidal ideation/behavior, but paroxetine may increase the risk of suicidality in the treatment of AD and venlafaxine for MDD. Findings from this review must be considered in light of potential limitations, such as the lack of comparative information about many antidepressants, the short-term outcomes and the quality of the available evidenc
