Biochemical and histological alterations of Mytilus galloprovincialis digestive gland after exposure to okadaic acid and dirivatives.
No full textElectrophoretical and histological analysis were performed on Mytilus galloprovincialis digestive
gland samples, in order to detect the presence of a previously identified protein ca 30 kDa MW,
synthesized during Dinophysis spp. blooms, and assess a possible correlation between the occurrence
of this protein and okadaic acid (OA) exposure by ingestion. Mussels were sampled monthly from July
2000 to November 2001 in the Gulf of Trieste (upper Adriatic Sea) and immediately processed. Parallel
samples were maintained in sea water plastic tanks and fed with marine invertebrate feed mixed with
OA and derivatives at different concentration of toxins for each experimental group (25 mg, 50 mg, 100
mg). In tank reared mussels fed with OA, degeneration of digestive cells and appearance of 24.6 kDa
protein were observed, while in wild mussels, neither histological alterations nor presence of a 24.6
kDa protein, were detected. A correlation between the toxins concentration and time of appearance
was highlighted, to demonstrate this protein is synthesized in response to OA and derivatives
exposure. About the identity of 24.6 kDa protein, it could be an enzyme involved in detoxification
reactions, probably Glyoxalase I
The Underwatermuse Project: a heritage for all
No full textThe international project UnderwaterMuse - Immersive Underwater Museum Experience for a wider inclusion (https://www.
italy-croatia.eu/web/underwatermuse, https://www.facebook.com/Project-UnderwaterMuse-106106884192806), funded
under the Interreg Italy-Croatia 2014-2020 Program (Priority Axis 3 “Environment and Cultural Heritage” - Specific Objective
3.1 “Make natural and cultural heritage a leverage for sustainable and more balanced territorial development”), saw,
as Lead partner, ERPAC - Regional Body for Cultural Heritage of the Autonomous Region of Friuli Venezia Giulia and, as
partners, the Ca’ Foscari University of Venice, the Public Institution for Coordination and Development of Split - Dalmatia
County RERA S.D., the Municipality of Kastela (Croatia) and the Puglia Region - Department of Tourism, Economy of
Culture and Valorisation of the Territory . The project aimed to enhance and make accessible the huge submerged heritage
of the affected areas, otherwise invisible or reserved for a few, through the creation of submerged archaeological parks /
paths and the narrative and communicative use of virtual reality. The activities carried out have implemented widespread
actions to raise awareness and involve local actors, as well as training diving guides, also for increased accessibility. A
public, geo-referenced web portal was created for the virtual exploration of submerged archaeological sites through voice
and text information, images and animations. The core of the project, however, was the development of a methodological
protocol for the enhancement of the underwater heritage, through pilot interventions aimed at transforming the sites into
parks or underwater archaeological trails or making them usable through the narrative and communicative use of virtual
and augmented reality and other multimedia tools. The various experiences have produced a breviary of good practices
(Auriemma 2023, Toolkit) for shared management models of accessible heritage, which fully complies with the principles
and guidelines of the UNESCO Convention on the protection of submerged heritage (2001, L. 157/2009) and above all of
the Faro Convention (2005) ratified by Italy on 23 September 2020: heritage as a common good, fundamental for the cultural,
social and economic development of individuals and communities. The Toolkit offers the roadmap, declined on the
various sites affected by the interventions, for the development of a management and operational framework that involves
all the interested parties in a participatory process, through Thematic Tables and Service Conferences; the steps include a
Program Agreement, the identification of the Managing Authority and the various roles and tasks, the scientific plan for
the enhancement of the site, the shared planning and construction of the park and / or the blue paths, the economic and
communication
Relative sea-level changes during the Holocene along the coast of southern Apulia (Italy)

Full text linkThe 2020 underwater archaeological research in the inlet of Torre Santa Sabina - Baia dei Camerini (Municipality of Carovigno,
Brindisi, Italy) represented the first phase of the pilot intervention of the Interreg Italia-Croatia UnderwaterMuse project. The project
aims to enhance and make accessible the vast underwater heritage of the areas involved; this will be done by creating submerged
archaeological parks and using virtual reality's narrative and communicative tools and platforms. During the 2020 campaign, different
survey activities were carried out using several techniques and methodology to produce the area's multi-scale documentation. First of
all, the entire stretch of coast was mapped with UASs (Uncrewed Aerial Systems) flights to reconstruct the coastal landscape in various
phases. Furthermore, an underwater photogrammetric survey carried out by expert scuba divers has been achieved in the wreck's aft
area (the site analyzed during the 2020 excavation activities). The fruitful synergy between the various actors involved and the support
of the territory and the community has allowed the achievement of this campaign's objectives, preliminary to the broader and more
articulated intervention foreseen for the following year
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
