Consumption and production patterns for agricultural sustainable development
Agriculture has always played a key role in feeding the world population and ensuring
the development of sustainable food production systems.
However, over recent decades, many farmers have over-exploited agricultural ecosystems
in order to increase their production and incomes. This has caused a reduction or
degradation of environmental sustainability, reducing farmers’ profitability and leading
many producers to abandon rural areas. Moreover, currently, over 820 million people in
the world are hungry, while a third of the food produced is lost or wasted, with negative
implications on economic, social and environmental conditions at a global level, highlighting
how different production, educational campaigns and consumption approaches are
needed. In this context, the 2030 Agenda for Sustainable Development aims at eradicating
poverty in all its forms and dimensions, by ensuring an economic, environmental and social
sustainable development. In particular, every country by 2030 should allocate public
and private financial resources to develop and carry out relevant strategies and programs,
by means of 17 sustainable development goals. One of them is represented by “ensuring
sustainable consumption and production patterns” in agriculture that, in addition to
feeding the world population, should ensure both the development of sustainable food
production systems and promote responsible consumption by consumers. According to
the Agenda, in fact, the sustainable cropping systems, on the one hand, have to increase
productivity and production, but on the other, they should reduce the negative social and
environmental impacts, thanks also to a sustainable changes in consumers’ choices.
Therefore, the aim of this Special Issue has been to collect scientific studies worldwide
dealing with the two main topics of the “ensuring sustainable consumption and production
patterns” goal: (1) the adoption of sustainable production patterns in the agriculture sector;
(2) the study of consumers’ behavior towards sustainable food products. This Special Issue
contains 13 papers that have tried to enrich the literature on agricultural sustainable development,
taking into consideration at least one of its three dimensions: the environmental,
social and economic dimensions
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
