A comprehensive assessment of geomorphosites in relation to both natural hazards and tourist fruition and activities
No full textIn the framework of the relationships between geomorphological heritage and natural hazards, the studies carried on by the members of the AIGeo Working Group on “Geomorphosites and cultural landscape”, focuses mainly on monitoring evolution rates of active geomorphosites in different morphoclimatic contexts, in order to evaluate risk scenarios in the context of tourism, and on the analysis of climate trends and quantification of rates of climate-related processes in areas of scientific and landscape interest. These lines of research are fundamental for forecasting evolutionary scenarios, especially regarding hazards and impacts on natural and cultural assets. There has been a growing interest in the mutability of geomorphological heritage (e.g. geomorphosites), as a consequence of both natural-climate and human pressure. Recent research has allowed inventories to be made for evaluating and analyzing geomorphosites not only in term of their geoheritage value but also for providing information on geohazards related to the intensity and frequency variation of climate-related superficial processes.
Within the framework of a comprehensive assessment of geomorphosites in relation both to natural morphodynamics and tourist fruition and activities, some main lines of research are developed:
• Assessment of natural hazard in tourist context interested by geomorphological active processes. The increasing interest in the natural environment has lead a growing presence of man in areas of active morphodynamics, thus increasing possible risk situations. Understanding the natural phenomena, also related to climate variability, and the potential consequences on tourist activities, is necessary for preventing risk situations.
• Investigations on active geomorphosites (sensu Reynard, 2004), interested by natural dynamic and climate-related processes that are able to induce changes in terms of hazards, impacts and global value. The problem of dealing with active geomorphosites is twofold: a) changes in geomorphological processes may directly influence the value of sites of geomorphological interest; b) active geomorphological processes may represent natural hazards and be a source of risk where tourist trails and activities are present.
• Contributions to the studies of interconnections between geomorphology and tourism in areas where natural processes and untouched environment are prevailing. Here possible risks are related to the environmental dynamics and the activities themselves. Researches on assessment of the natural risk for “extreme” sports like climbing or canyoning, are carried on, concerning dynamic processes, geotechnical conditions, and so on.
• Creation of geotourist maps to guide hikers through the most spectacular geomorphosites and to help tourists to better understand what they are looking at, using a simplified symbology, modified in order to highlight the landforms, which are then described with an easy scientific language. This kind of map will emphasize only the landscape elements that the tourist can recognize and observe as well as the possible hazards that could interfere with the hiking paths. A mapping campaign directed to identify and outline all geomorphological forms and processes, assessing their genesis and their state of activity: this represents the core for all further analyses and representations, functional to different purposes.
• Planning activities for sustainable management of risks related to the increasing interaction between geomorphological dynamics and human activities have their best test sites within Natural Parks. Here, risk monitoring and management activities can been performed by researchers in collaboration with territorial administration and environmental management institutions. As a first step, main hazards sectors have to be individualized along preferred alpinist routes and/or hiking tracks. For the field surveys, geomorphological maps can be coupled with digital track network. Visual monitoring of the unstable sectors is then developed by means of digital instrumentation, in collaboration with Park rangers. Finally, results on the hazards and risks studies can be used as teaching material for Park rangers and be popularized for the general public.
Valorization of technical and scientific data associated with the study of geomorphosites is crucial for enhancing geoconservation and dissemination of Earth Sciences contents. Development of innovative educational strategies within areas of high geoheritage value, can support the dissemination of scientific research results on geomorphosites and their response to climate change, favouring an easy understanding and comprehension of the landscape and of its hazards.
By defining risk as the consequences of a particular phenomenon of geomorphological instability on a particular human, social, economic condition of vulnerability, we envisage the role of scientific knowledge also in the management of natural hazards in touristic areas
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Full text linkWe 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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
