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
Priorities for afforestation areas on a national scale
No full textThis talk aims to present a set of priorities for afforestation areas on a national scale in Italy. With the increasing need for forest restoration and conservation, identifying priority areas for afforestation is critical for achieving the national targets for ecosystem services provision, biodiversity conservation, climate change mitigation and adaptation. Reforestation in fact is not a new policy, but its main objectives may not be the same in different parts of a country, and they may depend on different environmental, social, climatic or cultural needs. This is why nation-wide reforestation projects, such as Parco Italia project in Italy, need to prioritize between different and competing demands.
To achieve this goal, we carried out a survey among experts and professionals with forestry, ecological or agronomic backgrounds. From the synthesis of the results, we identified the main goals for afforestation in Italy, and a suggested set of environmental variables (e.g. distance from roads, distance from forests, population density, ...) to be mapped and used to rank high priority areas.
For each considered goal for afforestation (e.g. connectivity, climate adaptation, ...), we produced a map with a resolution of 1 km (a raster file made with GIS). This not only shows the potential reforestation of the Italian territory, but shows the areas with the highest priority, i.e. where the effects of reforestation can best respond to the considered objective. We expressed the priority with a score between 1 and 100 that we obtained with an Analytic Hierarchy Process (AHP), a method which allows to compare several alternatives in relation to a plurality of criteria.
We will also highlight the potential benefits of afforestation, including carbon sequestration, soil conservation, and recreation opportunities. Our approach integrates GIS analysis, stakeholder engagement, and decision-support tools to identify areas with the highest potential for afforestation and to engage local communities and private landowners in the process. Our findings can provide guidance to policymakers and practitioners in Italy to achieve a more effective and efficient afforestation strategy, contributing to the country's commitments to the Paris Agreement, the EU Biodiversity Strategy and the EU restoration law
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
Riflessioni su paesaggio forestale e tutela dei beni culturali
Get PDFAccording to the European Landscape Convention (ELC), a landscape means “an area, as perceived by people, whose character is the result of the action and interaction of natural and/or human factors”. Therefore, both human actions and natural processes play a role in shaping the landscape, which is, by this definition, ever changing. “Protecting” the landscape therefore means understanding, accepting and preserving such agents of change that have created it. Conversely, protective measures should not be designed to “freeze time”, nor to restore natural or human-influenced landscape features that have long ceased to exist. These basic concepts, delineated 20 years ago in Florence, are met in some parts of Italy by a dubious interpretation. Land- scape protection agencies (Soprintendenze Archeologia Belle Arti e Paesaggio) seem to be oriented towards stopping or limiting the traditional activities that have shaped the current Italian forest landscape, with the purpose of increa- sing the forest cover for “aesthetic” reasons. Such narrow view contradicts the aims of the ELC and of the related national rules and mechanisms of land- scape conservation
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
