Integrated Numerical Models in Coastal Areas: An Example of Their Application in the North Adriatic Sea
No full textRecent decades have witnessed considerable
developments in the field of integrated numerical
models used for simulating dynamic
processes in coastal areas, that can now provide
quantitative support to decision makers
for questions such as erosion and coastal
vulnerability.
Improvements in various theoretical formulations
and an on-going increase in computing
power (alongside the growing availability of
long-term observations and numerical output
from meteorological and sea-state models) allow
the implementation of high-resolution and
long-term applications.However, the efficient use of these numerical
tools is a function of their capacity to describe
a variety of physical processes that are ‘integrated’
amongst themselves correctly. Indeed, from
the air-sea interface to the turbulent mixing of
water masses and the water-sediment interaction,
integrated numerical modelling has to face
a series of scientific and practical challenges still
open. Examples include the non-linear interaction
of waves and currents, the problem of
turbulence, the modelling of resuspension and
sediment-transport processes, the role of longperiod
waves in generating beach and dune erosion.
Dealing with these using numerical models
is necessary for a variety of reasons, from protecting
the coast to search-and-rescue activities
and support for marine construction work of all
types.Unpublished4.4. Scenari e mitigazione del rischio ambientaleope
Soil Displacement. Landscape Project as an Infrastructure Across Building Geography and Grounding Metabolism. The Case Study of Pialassa Piomboni Constructed Wetland in Ravenna
No full textIn current circumstances, man has the great responsibility of better managing the effects and products of those intense anthropic processes—such as waste disposal or excavation materials—which cannot be assimilated in a reason-able time by spontaneous renewal cycles. A systemic approach is needed for coor-dinating man-made metabolic procedures concerning the inevitable phenomena of urban and territorial transformation and ecosystem protection, admitting that one can be consequent and functional to the other. By being open to a strongly inter-disciplinary approach, landscape design can offer precise and contextualized design solutions which may involve large temporal and spatial scales in reference to the extension of the problem. The proposed case study of the Ravenna commercial docks shows how the progressive expansion and continuous maintenance of the seabed through dredging has led to the creation of newly constructed wetlands in continuity and balance with existing ones. In particular, the excavated material was transferred into Pialassa Piomboni (protected wetland pSCI and SPA) through topo-graphic modeling suitable for improving the ecological state of the humid area. After the intervention, the Pialassa area is expected to increase its ecological potential. Such an approach has turned waste treatment into an opportunity, allowing the wetland system to grow stronger and reducing costs compared to transporting the material to a remoter site. Several years late, building on the site is still ongoing in 2020. The project time schedule was not completely adhered to, with a strong impact on the expected outcome. In light of this experience, the contribution discusses different solutions for integrating and observing the regenerative time of nature in the design process and soil handling in spatial planning by activating new metabolic processes in its replacement in the environment
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
