Epitonium (Asperiscala?) oliverioi, a new species of Epitoniidae (Gastropoda) from Madagascar
No full textEpitonium (Asperiscala?) oliverioi new species (Gastropoda, Ptenoglossa, Epitoniidae) characterized by two different teleoconch microsculptures is described from the Tuléar region (SW Madagascar). A brief comparison of its spawn and radular morphology with those known of other epitoniids is also given in order to provide further characters for specific and supraspecific classification
Yoldiella seguenzae, a new species of nuculanidae (bivalvia; nuculoida) from the Mediterranean Sea
No full textA new species, Yoldiella seguenzae (Bivalvia, Nuculoida), from a deep sea community off the north east coast of Sardinia (Mediterranean Sea), is described. Morphometrical and statistical comparison with the very similar Yoldiella philippiana (Nyst, 1845), and general morphological comparison with other Mediterranean and Atlantic species support the distinctivness of Y. seguenzae which is distributed in deep waters of the Central Mediterranean Sea, Alboran Sea and the Atlantic Ocean
Austrodaphnella yemenensis new species (Gastropoda: Turridae) from Yemen, Red Sea, with notes on A. Alcestis (Melvill, 1906)
No full textThe genus Austrodaphnella Laseron, 1954, previously known only from Australian waters, is here reported from the Arabian Peninsula. Two species occur: A. yemenensis new species, from Yemen, Southern Red Sea, and A. alcestis (Melvill, 1906) new combination, a deep water species known only from the Gulf of Oman. SEM photographs of both species are provided
The termophilous species Echinolittorina punctata as a new descriptor of tropicalization in the Mediterranean Sea - first data.
No full textData suggest that the prosobranch gastropod Echinolittorina punctata (Gmelin, 1791) (Mollusca, Gastropoda) has extended its range northwards along the Italian coastline due to climate variability in marine conditions. Its ease of identification and mesolittoral habitat suggest this species may be a new practical indicator of Mediterranean Sea changing conditions, easy to monitor

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
