Automated extraction of geomorphometric properties of relic sandy bodies in the continetal platform from a digital map geo-referenced in a GIS: the case of Cilento.
No full textThe retreat of beaches in the world is increasingly evident., often due to a negative sediment balance. To prevent this, or at least to mitigate the effects of the retreat, were considered engineering structures and / or compensatory measures with results that were not always effective. Among the best measures, the artificial beach nourishment is well considered, because of its negligible environmental impact as well as for a discrete outcome with low costs. This intervention consists in sand dredging from the continental shelf, or from adjoining shorelines in progress, or even from the access channels to ports and then the discharge of it on the beach. The main difficulty is in identifying these "deposits of sediment" in the continental shelf which are considered the most relevant in terms of volume and likeness with the beach sediments adjacent to it. This contribution has attempted to extract automatically fOlIDS related to submerged ancient beach ridges, derived from the deposition of sand during the lowstands of the sea during the late Pleistocene, though a digital terrain model. The continental shelf, where the extraction was performed automatically. is placed at the south-eastern Tyrrhenian margin. It is in front to a high morphostructural, the Cilento promontory. bounded by the subsidence basins of the Gulf of Salerno - Piana del Sele River. NW. and Gulf of Policastro. SE.
The map of this continental shelf seabed was performed using high-resolution bathymetric surveys totaling 675 km run
with multibeam echo sounder at a rate not less than 50 kHz. insonificando the seabed in a bathymetric range between 0.5 to 150 m. Subsequently for the sedimentological characterization and. in particular, of the acoustic response on the type of bottom sediments marine mobile and its immediate substrate (SAVINI et al., 1995 cum bibl.), were evaluated for the same extension of the acoustic profiles with CHIRP sonar technology. high-resolution, The survey results were integrated with bathymetric charts of the Hydrographic Institute (1971). scale 1:100,000, appropriately georefereuced. with morphological and bathymetric data obtained from the geomorphological map in Ferraro et al. (1997) and with the morphological and sedimentary data collected from Pennetta (1996 a, b), De Pippo et al. (1996) and De Pippo and Pennetta (2000. 2004). All these data, taken together, allowed to obtain in a GIS environment the geomorphological map scale 1: 150.000 and to identify potentially areas for artificial beach nourishment. For the management and processing of data were used: the design software Autodesk Map 2008, which allowed the georeferencing of bathymetric charts of the Hydrographic Institute of the Navy and in the geomorphological Ferraro et al. (1997) in the reference system UT~II and interpolation of all the points relating to different depths, in order to obtain the preparation of the Charter Bathymetric. The processed data were exported to SHP in a condition suitable for use in other software environments, was then carried out a series of integrated applications of GIS ESRl ArcGIS Desktop 9.2, through which it was possible the drafting of other thematic maps. The applications used are ArcMap, ArcCatalog, and Arc'Toolbox, accompanied by instruments and controls GIS application ArcMap for all activities on mapping. editing and querying da.ta and apply ArcCatalog to organize and manage data. Through the application Arc Toolbox, organized collection of geoprocessing tools. operations were performed on GIS data available. The cartographic processing were represented in the reference system UTM. WGS 84 - ZONE 33N.
The basis on which different calculations were made was identified in a Digital Elevation Model (DEM) of the area made using the data in depth, these values were obtained by digitizing the depth contours from the bathymetric map in scale 1:10,000. The detail of the data permitted high-resolution raster model used. consisting of cell sizes of 1Oxl 0 meters. In order to encode the
entities geomorphological of interest, it was decided to analyze. from the point of view of the statistical distribution, the values relating t.o the key characteristics that can be derived starting from the The morphology that characterizes the platform, is rather articulated owing to the presence of faults in the substrate that generate displacements in the seabottom and therefore a structure of high and low areas, The platform is characterized by a wideness and an edge somewhat variable. The edge is located generally at a depth of 200 m except for the area overlooking the coastal stretch between Punta Licosa and Acciaroli, where it. reaches a depth of about 230 m, and for the southeastern area overlooking Punta Infreschi and the Gulf of Policastro, where it is much shallower with values lower than -100 m.
The average gradient varies from 0.30 in the north and gradually increases going southward where in the narrowest portion of continental shelf reaches 0.8°. Its maximum width of about 30 kill is measured at north-west, and then it gradually shrinks down proceeding towards south-east, for instance, it is 13 km to the beam of the Telegraph Tower and 7 km offshore of Cape Palinuro. In the Gulf of Policastro, finally, it is characterized by a low wideness, which reaches 7.5 k111,and high slope gradients.
On the platform were identified several limb of marine abrasion ten-aces with the edge located respectively at a depth of 30 m, 50 1119, 0 ui, 110111. 130 in, 140 m and 150 ill. Such terraces were modeled in coincidence of sea level changes occurred during the Pleistocene. Generally, they are evidenced from the hard substrate tha.t frequently rises from the bottom as well as from the irregular morphology surveyed at depths between 20 111 and 150 ill.
Depressed areas were also recognised, filled by successions of sediments in various sizes. These areas are related to extensional processes occurred 011 the southeastern sector of the Tyrrhenian Sea. probably in the Plio-Pleistocene, along NW -SE direction. Instead. a depressed area, that connects with the valley of the River Alento. is controlled by faults with anti-Apenninic trend (NE-SW). as evidenced in the intermediate portion of the platform. We also identified some channels that cut the bottom. forming a paleo-drainage network of subaerial origin, whose outlets are fans of sediments similar to the mouth complex. detected through the analysis of the seabottom morphology. Among other geomorphological features shown in the geomorphological map, two elongated sedimentary bodies with a trend NW -SE are focused at a depth of between -120 and -170 III parallel to the edge of the platform. They extend for about 23 km offshore of Punta Licosa. 3.5 kHz subbottom profiles recognise these bodies as overhead structures from the bottom, where the sea side is always presented with a slope greater than the coast side. They are characterized by a type of echo with the bottom indistinct without reflections in the substrate (Ferraro et aI., 1997), indicating the presence of sandy deposits generally more reflective than the pelitic deposits. The top of these structures is irregular and sometimes is topped by a thin layer of Holocene sediments.

L'effet de l'amorçage du stéréotype du genre sur l'effort cognitif
No full textCette recherche étudie l'effet de l'activation implicite d'un stéréotype de genre (visages d'hommes et de femmes neutres) et de la difficulté sur l'effort cognitif lors d'une tâche de mathématiques. Nous faisons l'hypothèse que les participantes de sexe féminin amorcées à l'aide des visages de femmes vont fournir plus d'effort lors d'une tâche facile, à cause de l'activation en mémoire implicite du stéréotype soulignant que les femmes sont inférieures aux hommes en mathématiques, en comparaison aux participantes amorcées à l'aide visages d'hommes. Lors d'une tâche difficile nous nous attendons au pattern inverse, c'est-à-dire que les participantes amorcées à l'aide de visages d'hommes vont fournir plus d'effort, que celles amorcées à l'aide de visages de femmes. Nous prédisons, par conséquent, un effet d'interaction entre les visages de femmes et d'hommes et la difficulté de la tâche de mathématiques. L'effort à été mesuré avec des indicateurs cardiovasculaires (pression systolique, diastoliques et fréquence cardiaque)

Mapping Energy Frames: an Innovative Approach Engaging with New Forms and Types of ‘data’ in Social Media Analysis to Frame Energy Demand
No full textUnderstanding how individuals consume energy is considered to be a fundamental step in improving energy conservation and stimulating energy efficiency. Multiple studies have shown how feedback loops encourage en-ergy conservation and efficiency among policy makers and citizens. Fischer (2008), for instance, explores the ways in which a sense of competition, social comparison, and peer pressure impels people to adopt better energy consuming behavior. The online platform ‘Social Electricity’ allows citizens to compare energy footprints with friends, neighbors, or other users. This process, Kamilaris, Pitsillides, and Fidas (2016) argue, affects people’s energy awareness, making them more sensitive to the environment and motivating them to behave more sustainably. Many other energy-saving applications have been developed (Albertarelli et al., 2018), which exploit gamification and social interaction to promote energy-efficient lifestyles.Web Information SystemsHuman-Centred Artificial Intelligenc
Individual or Group-based Approach to the Assessment of Preschool Children: A Comparison using the INTERGROWTH-21st Neurodevelopment Assessment (INTER-NDA)
No full textIntroduction: It is unclear if the assessment of early child development can be carried out using a group approach, as opposed to individually.
Objective: To compare scores obtained from children aged 22 to 26 months assessed either in small groups or individually using the INTERGROWTH-21st Neurodevelopment Assessment (INTER-NDA), which measures cognition, language, motor skills, behavior, attention and socio-emotional reactivity.
Methods: A small group based strategy for administering and scoring the INTER-NDA was developed. Thirty-six preschool children attending four Centros de Cuidado y Atención Infantil of the Sistema Nacional para el Desarrollo Integral de la Familia (DIF) of Mexico were assessed in small groups of three children by a teacher specifically trained in the INTER-NDA. A second teacher, unaware of the group results, assessed the children individually on a different day. The sex, age, weight, length and head circumference of the children at the time of assessment were recorded.
Results: INTER-NDA domain scores for group and individual assessments were statistically significantly correlated (range r=0.35 to r=1.00) for all domains except receptive language (r=0.25, p=0.14). Bland-Altman analysis showed agreement between group and individual scores for the language, behavior, attention and socio-emotional reactivity domains, and consistency (but not agreement) between group and individual scores for the cognitive and motor domains. None of the differences between group and individual scores examined were statistically significant, even after adjusting for the children’s age, sex, nutritional status and location of the preschool.
Conclusion: INTER-NDA domain specific scores obtained following group and individual assessment of children aged 22 to 26 months are consistent. It is feasible for trained preschool teachers to administer INTER-NDA at both group and individual level.</jats:p
‘If we want things to stay as they are, things will have to change’
No full text‘If we want things to stay as they are, things will have to change’"Se vogliamo che tutto rimanga come è, bisogna che tutto cambi"(Il gattopardo, Giuseppe Tomasi di Lampedusa)It is now few months that I have been appointed as new editor in chief of the Veterinaria Italiana and first of all I would like to express my sincerest gratitude to Ferdinando Arnolfo, the Director of the Istituto Zooprofilattico Sperimentale dell’Abruzzo e del Molise ‘G. Caporale’, and his staff for the honour they have bestowed on me. It is for me a very new and exciting challenge. I firmly believe the journal has the potential to turn into a successful and important voice in the scientific veterinary community. As you might be aware, Veterinaria Italiana is an indexed journal that recently received the impact factor, thus acquiring international recognition alongside major scientific journals.In view of this, it is only right and proper to acknowledge the previous team for their collective work for bringing the journal to its the current position. First of all, I would like to thank the previous director, Vincenzo Caporale, who has always strongly believed in Veterinaria Italiana, putting in a great deal of effort and resources when others doubted the success of this initiative. Special thanks are also due to the previous associate editor, Gill Dilmitis, who has been one of the pillars of the journal taking care of all author needs always with extreme enthusiasm and competency. I am afraid that Mariarosaria Taddeo, the new associate editor, and I will have the daunting task of meeting their high standards and level of competence; even more so because we realise that, as in numerous other activities, it is easy to start but it is always harder to maintain the status quo. Nonetheless, if on one hand we know that it is a difficult task, on the other hand we are sure that we and the other team members will do our best to improve the current position of the journal. We have already created a new and modern format for Veterinaria Italiana so that it may compete with other international and better known scientific journals. Soon Veterinaria Italiana will be provided with an electronic platform and the DOI (Digital Object Identifier). Both, I am sure will be extremely beneficial to editors, referees, and authors alike. Many other innovations will be introduced to improve the readability and quality. All these changes, however, will not distract from our main purpose which is to provide information about new research results on veterinary and public health field, ensuring their reliability and integrity through relevant, strong and comprehensive proofs. Veterinaria Italiana will still represent the voice of authors who do not have the opportunity of disseminating their results widely, of course, being the Italian journal in Veterinary field with the highest impact factor, it is privileged to have the opportunity of publishing the results of the best Italian research teams on public and animal health. For myself, I know that a journal is a powerful educational tool. I will try to ensure independence of editorial work and good editorial practice as defined by international editorial organizations, bearing in mind that the work invested in a journal is never wasted as it stimulates and provokes research and culture of scientific communication
Retinal Nerve Fiber Layer thickness in Dominant Optic Atrophy: measurements by Optical Coherence tomography and correlation with age.
No full textPurpose: To measure the retinal nerve fiber layer (RNFL) thickness by means of optical coherence tomography
(OCT) in patients with dominant optic atrophy (DOA).
Design: Cross-sectional study.
Participants: Thirty-three patients from 15 pedigrees with DOA harboring heterozygous mutations in the
OPA1 gene and 43 healthy subjects were enrolled.
Methods: The RNFLs of DOA patients were studied by OCT and compared with those of 43 healthy subjects
matched for age and optic nerve head (ONH) size.
Main Outcome Measures: Retinal nerve fiber layer thickness.
Results: Dominant optic atrophy patients revealed a significant RNFL thickness reduction in all quadrants,
with a preferential involvement of the temporal and inferior sectors. The progressive decline of RNFL thickness
with age was similar to that observed in healthy subjects and was more evident in the 2 quadrants with higher
residual amounts of fibers, that is, the superior and the inferior. The temporal quadrant was profoundly depleted
of fiber so that the further rate of loss of microns per year is close to zero, whereas the nasal quadrant was spared
the most by neurodegeneration.
Conclusions: The present findings, taken in conjunction with the authors’ previous description of small ONH size
in DOA, strongly suggest that patients with this disease are born with fewer optic nerve axons and support the
hypothesis that subsequent visual loss depends on further age-related loss of fibers, which also occurs in controls.
