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
Characterizing the agroecological transition of Italian farming systems using FADN database
No full textThe Common Agricultural Policy 2023–2027 encourages the transition towards sustainable agriculture in line
with the goals of the European Green Deal. Agroecology is gaining recognition as a valuable approach to enhance
the sustainability of faming systems. However, there is limited understanding of the status quo of the farming
systems and their readiness for transition, especially at large scales such as the national one. This paper in-
vestigates the current uptake of agroecology across the Italian farming systems, by adapting the Tool for Ag-
roecology Performance Evaluation (TAPE) methodology to use secondary data from the Farm Accountancy Data
Network (FADN). Besides, a panel between-variance regression was estimated to identify the key determinants of
the transition degree. The results indicate that agroecology has not yet been widely adopted by the Italian farms.
Additionally, factors such as the type of farming, farm management, farm economic and physical size, farm
location, and farmer’s socio-demographics play a significant role in explaining the variation in the transition
intensity towards an agroecological production system. The findings provide a knowledgebase for developing
targeted policies and monitoring progress in agroecological transition. The study confirms the viability of using
the FADN to evaluate the degree of agroecological transition, while also revealing information gaps. Although
essential environmental and social information will be included in the forthcoming Farm Sustainability Data
Network, further integrative sources should be explored to capture multifaced aspects of agroecological transi-
tion within broader agri-food systems, while in-depth studies based on primary data collection could offer more
detailed and nuanced insights
Characterizing the agroecological transition of Italian farming systems using FADN database
No full textThe Common Agricultural Policy for the period 2023-2027 encourages the transition towards sustainable agriculture in line with the goals of the European Green Deal. Agroecology is gaining recognition as a valuable approach to enhance the sustainability of faming systems. However, there is limited knowledge of the status quo of the farming systems and their readiness for transition. This paper investigates the agroecological performances of the Italian farming systems and their structural and organizational determinants at farm level. The study is based on the adaptation of the Tool for Agroecology Performance Evaluation (TAPE) methodology to use Farm Accountancy Data Network (FADN). Also, a panel between-variance regression was estimated to identify the key determinants of the degree of transition. The results indicate that the agroecological approach has not yet been widely adopted by the Italian farms. Additionally, factor such as farm location, farm structural characteristics, type of farming, farm management, and farmer’s socio-demographics play a significant role in explaining the variation in the adoption of an agroecological production system. The findings provide a knowledgebase for developing targeted policies and monitoring progress towards agroecological transition
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
Urban food strategies and plans: considerations on the assessment construction
Get PDFAbstract In a context of growing attention to the issue of feeding the city, this article focuses on the role of the assessments guiding the processes of urban food policy and planning to reach Sustainable Food Security. The starting point is a collection of experiences dealing with some cities that in recent years have launched strategies for developing healthier and more sustainable food systems. Their analysis highlights the innovations in the construction of cognitive frameworks supporting food policies and planning, as well as the difficulties to explore the food phenomenon on the qualitative and quantitative level. Within a current research meant to address the food agenda in Venice, the authors take advantage from the case studies comparison to propose key themes and investigation methods a preliminary assessment of the existing food system. Considering the strong impact of the huge tourist flow that invests the city, daily, the foodservice sector is considered as the main challenging and strategical core-area for boosting impactful changes in the urban food system
