Declaration of "outstanding Universal Value" and the commodification of the image of a city
No full textThe historic center of Naples has been placed in the list of the UNESCO World Heritage since 1995. Its candidature is synthetized in the record n. 726, where the area, its boundaries and its features are describes, as well as the reasons to consider it of "Outstanding Universal Value":"Naples is one of the most ancient cities in Europe, whose contemporary urban fabric preserves the elements of its long and eventful history. Its street pattern, its wealth of historic buildings from many periods, and its setting on the Bay of Naples give it an outstanding universal value without parallel, and one that has had a profound influence in many parts of Europe and beyond"
Il paesaggio senza mappa

Anisakis nascettii (Nematoda: Anisakidae) from beaked whales of the southern hemisphere: morphological description, genetic relationships between congeners and ecological data
No full textA new anisakid nematode, Anisakis nascettii n. sp., is described from beaked whales Mesoplodon spp. off the coast of New Zealand and South Africa. Morphological and molecular (allozymes and mtDNA cox2 sequence) data were used for diagnostic and identification purposes. Among the 19 allozymes studied, 10 were found to be unique and characteristic for A. nascettii n. sp. Analysis of allozymes demonstrated reproductive isolation from A. ziphidarum Paggi, Nascetti, Webb, Mattiucci, Cianchi & Bullini, 1998 and mtDNA cox2 sequences depict this Anisakis species as a distinct and unique entity. Key morphological diagnostic traits for A. nascettii with respect to the genetically closely related species A. ziphidarum include: spicule length, the spicule/body length ratio, the arrangement of the caudal papillae and the shape of the plectanes of the adult males. Genetic data confirmed that Anisakis sp. A of Pontes et al. (2005), which was partly described by Iglesias et al. (2008), and Anisakis sp. of Valentini et al. (2006) are conspecific with A. nascettii. Both molecular and morphological data indicate that the new species belongs to the 'ziphidarum-group'; however, it is genetically very distinct from A. ziphidarum (D(Nei) = 0.69, K2P = 0.09), as well as from all of the previously genetically characterised Anisakis spp. All tree topologies inferred by different methods (MP, NJ and Bayesian) support the finding that A. nascettii n. sp. and A. ziphidarum are sister-species. It is also confirmed that A. nascettii n. sp. is, at the adult stage, a parasite of beaked whales of the genus Mesoplodon, whereas, as a larva, it has been identified from the squid Moroteuthis ingens Smith. Furthermore, Mesoplodon bowdoini Andrews represents a new host record for A. ziphidarum. The parallelism between the clade formed by these two anisakine taxa, i.e. A. ziphidarum and A. nascettii, and that formed by their definitive hosts further supports the hypothesis of host-parasite co-evolutionary relationships, as previously suggested for Anisakis spp. and their cetacean hosts
A kaleidoscope on ordinary landscapes: the perception of the landscape between complexity of meaning and operating reduction.
No full textThis research has started from some issues affecting the debate in progress on policies for landscape and confronts itself with the actuality of a review of some paradigms of interpretation that could substantiate the practice of landscape transformation.
The main questions that will be addressed is what the ordinary contemporary landscape is, experimenting the perception as a tool at first of interpretation, therefore potentially operating, from the demands of the European Landscape Convention, according to which “Landscape means an area, as perceived by people, whose character is the result of the action and interaction of natural and/or human factors”.
Assuming the landscape perception as a means of expression of the relationship between society and territory, this study develops and tests a methodology for its comprehension, through kaleidoscopic visions which interpret the variety of the situated looks.
By means of the methodology we aim to explore how a variety of people experience landscapes and – as a consequence - how they perceive them. The proposed approach refers to the landscape perception as a complex system in its multiple dimensions (physical/natural, symbolic/cultural, personal/ collective) that becomes significant as expression of a contemporary condition of living places. It begets a thinking material to understand values and themes, on which could be possible basing actions and policies for landscape.
The Kaleidoscope, which is here proposed as device to represent perceived landscapes, derives from the sense of this research. Actually, the explicit reference to ordinary landscapes implies the awareness that the contemporary landscape can not be understood through a tale made of synthetic and mimetic/typological representations, but is expressed predominantly in ordinary contexts, whose not consolidated images neither shared attributions of meanings exist.
The Kaleidoscope has set as a composition of diagrams and narratives, which are translated in looks type and themes for action, contributing to reify the problems the landscape poses as challenges to planning and the perception is offering to return.
The research is substantiated by a long experimental stage, when - through an experience of understanding the perceived landscape in a valley place in Trentino - the themes tackled in the theoretical-critical part pit themselves strength the realm of a contemporary landscapes and the specificity of the ordinary ones, which more than others claim the experimentation of interpretative and operational tools.
The experience has been set up as a cognitive practice, able to be consolidated and repeatable in the ordinary planning processes. It can therefore be understood as a paradigmatic experience of approach to contemporary landscape
Contracaecum gibsoni n. sp. and C. overstreeti n. sp. (Nematoda: Anisakidae) from the Dalmatian pelican Pelicanus crispus (L.) in Greek waters: morphological and genetic evidence
No full textTwo new species of Contracaecum Railliet & Henry, 1912, previously referred to as C. multipapillatum sp. A and C. multipapillatum sp. B by Nascetti et al. (1990) from the Dalmatian pelican Pelecanus crispus (L.) in the Ambracian Gulf off Greece, are described as C. gibsoni n. sp. and C. overstreeti n. sp., respectively. Morphological analysis and the differential diagnosis of genetically recognised male specimens of C. gibsoni and C. overstreeti with respect to C. multipapillatum (von Drasche, 1882) (sensu lato) from Egretta alba (L.) in northern Colombia and other morphologically related Contracaecum spp. enabled the detection of differences between the two species in a number of characters, including spicule length and the shape of its tip, and the arrangement of the proximal and distal papillae on the male tail. Accordingly, formal descriptions are presented for C. gibsoni n. sp. and C. overstreeti n. sp. from P. crispus. The genetic characterisation of the two taxa is based on 20 allozyme loci and sequence analyses (519 bp) of the mtDNA cox2 gene. Reproductive isolation was demonstrated between these two taxa, which sympatrically infect the same definitive host, and fixed allele differences between the two species were found at some (Aat-2, PepC-1, PepC-2 and Pgm-1) of the 20 allozyme loci analysed. Their genetic divergence, estimated at the allozyme level, was D (Nei) = 0.31. The genetic relationships of C. gibsoni and C. overstreeti with respect to C. multipapillatum (s. l.) collected from E. alba in Colombia, as well as with other congeners from fish-eating birds which had previously been genetically characterised using the same genetic markers, i.e. C. rudolphii A and C. rudolphii B of Bullini et al. (1986), C. septentrionale Kreis, 1955, C. microcephalum (Rudolphi, 1809), C. bioccai Mattiucci et al., 2008, C. pelagicum Johnston & Mawson, 1942 and C. micropapillatum (Stossich, 1890), were inferred from mtDNA cox2 sequence analysis. The MP, NJ and BI trees obtained were congruent in depicting C. gibsoni and C. overstreeti as closely related species but quite distinct from each other and forming a subclade with specimens of C. multipapilllatum (s. l.) from E. alba (L.) in Colombia. This subclade was also found to be distinct from the remainder of the taxa considered
