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
Protection and enhancement of the « Geodiversity » of Beni Ghedir Valley (Tataouine, south-east Tunisie)
No full textDuring last years the IUGS (International Union for Conservation of Nature and Natural Resources) and UNESCO has suggested to start projects with the idea of integration of the protection of geodiversity with sustainable economic development (Projects Geosites, Natural Monuments, etc). A better understanding of the links between cultural identity and geodiversity can help people appreciate the relevance of geodiversity in their everyday lives. In particular these links can be used to make local communities aware of their local resources and to encourage them to participate in promoting and conserving them.
The research conducted in the last two years in the area of Tataouine (south-east TUNISIE) between IGRG- University of Bologna and AAMTT- Tataouine, have helped to identify in the valley of Beni Ghedir an important witness of geologic, landscape, cultural and socio- economic values, that the local authorities are keen to preserve. The overall objective of the project for the development of this valley being the exploitation of natural and anthropic benefit of sustainable development in taking specific objective the rehabilitation and development.
The Béni Ghedir valley develops in the most southern sector of the «Chain of Matmata», a prominent monoclinalic structure with elevations of about the 300-600 m, characterized by the widespread presence of geomorphologic evidences of the type of "cuestas" or other forms of modelling of slopes linked to selective erosion . Particularly the chain is heavily dissected by a dense hydro-graphic network system where water erosion has configured a very dissected landscape valleys, gullies and badlands.
Late Jurassic – Early Cretaceous exposed strata mainly consist of an alternation of coastal to shallow-carbonatic marine deposits. Furthermore, a variety of fossil remains (primarily terrestrial and marine vertebrates, fishes, invertebrates, megaplants and remains of dinosaurs) support intervals dominated by terrestrial sediment supply and deposition. Such beds are fundamental to the reconstruction of ancient ecosystems as well as in the reconstruction of the complicated palaeogeographic setting of the area.
From a geomorphological and landscape point of view the Beni Ghedir valley show a typical arid climate, somewhat very aggressive because rainfall is highly irregular and usually intense and causing intense erosion (annual average rainfalls range between 200 and 300 mm, but daily intensities may reach 150 mm). Similarly, the accentuated topography promote the rapid concentration of runoff water thus increasing their faculty erosive.
The water management is dominated by a complex system of “jessour”, a very ancient typical hydraulic system at small scale used to bank the runoff from the mountain chain. The jessour (plural of a “jesr”) are hydraulic units made of three components: the impluvium, the terrace and the dike: 1) the impluvium is the area destined for collecting and channelling of the meteoric water; 2) the terrace, formed progressively by the decantation of the carried sediments, is the area where the agricultural activities are carried out (generally olive, fig, almond, date palm, legumes etc); 3) the dike (local called “tabia”) is a barrier intended to block the sediments and run-off.
The jessour influence and control almost completely the traditional agroforestry farming of the area (trees such as date palms, olives, figs, almonds, etc). Maintenance of traditional methods can reduce the negative impacts caused by modern activities and support their positive characteristics
The territorial and environmental framework is completed by the presence of a typical "Ksar of mountain", the oldest form of rural housing in the area. It is a hilltop collective granary with single or multi-level long barrel vaulted storage rooms («ghorfas») which are stacked and walled to form a fortified ksar
The Ksar was conceived to protect its residents and secure subsistence from ..
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.
