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
Integrating Geographical Data with Vegetational Surveys for Developing a Management Plan in an Area with High Environmental Value.
No full textPlanning conservation and management measures in protected areas, characterized by high landscape and environmental value, requires synergical con-tributions from multiple skills. In particular, when these areas seek opportunities for tourism valorization, the management activity becomes extremely important and requires an appropriate technical approach. With reference to an area of high environmental, landscape and archaeological value, such as the ‘Pulo di Molfetta’ (Municipality of Molfetta – Southern Italy), some georeferenced floristic surveys have been carried out, so obtaining a list of tree, shrub and herbaceous species, with particular reference to invasive species, as well as to those included into the Habitat Directive. Further surveys have been then carried out on plant health status and mechanical tree stability as well. This survey, allowed to detect a priority Habitat (Laurus nobilis, cod. 5230), a residual forest coenosis very ancient, having an ecological, cultural and historical value, which deserves to be protected and valorized.
A very-low altitude drone survey has been also carried out, to create a geo-localized 3D model, included as the base for a Geographical Information System (GIS), implemented for checking the formal consistency of the cartographic layers and detecting the floristic-vegetational habitat in this area. This approach has revealed suitable for the generation of a high-resolution orthophoto and highly detailed point cloud, to be used for further environmental studies. It enables also policy makers, to implement proper planning and management strategies, together with appropriate actions aimed to mitigate anthropic interventions, so allowing the development of a more sustainable tourism
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

Sustainable Rural Buildings for Implementing the Agroecology Concept at Territorial and Landscape Level in the Mediterranean Area
No full textAgroecology is a strategy aimed to combine technical, ecological and social principles, to design and manage agro-food systems, while protecting biodi-versity, promoting soil health and optimizing resource management. This approach maximizes relationships among humans, animals, and plants within their natural environment, addressing global food demands, while minimizing the environ-mental footprint of agricultural activities. Fostering agroecology at territorial and landscape level offers a holistic approach to sustainable development, combining technical, social, political, economic, and cultural factors with local realities. In this framework, Agricultural and Biosystem Engineering may play a decisive role, particularly thanks to its contribution to the analysis and exploitation of:
-) Natural materials for farm buildings-such as wood, stone, as well as natural fibers (wool, straw, reed, hemp, etc.), and recycled waste biomass, improving mechanical and thermal characteristics of building components and introducing new bio-based materials.
-) New technologies for land survey, planning and management-includ-ing digital tools, remote-sensed data, Geographical Information Systems, Internet of Things (IoT), etc., able to optimize crop management, while also reducing chemical inputs and natural resource consumption.
This review paper presents the advancement of research and study activities on Agricultural and Biosystems Engineering and their contribution to the imple-mentation of the Agroecology concept, aimed to increase the sustainability of agricultural activities, thanks to the implementation of new specific study courses as well as whole curricula, while opening new prospects of development for the scientific community
