Full text linkAgriculture, environment, and sustainable natural resources: Approaching land classifications from the perspective of eco-development
No full textThe endogenous development of local systems progresses through the evolution of agricultural space and natural resources, promoting the integration of agricultural space with other territorial aspects. This integration reflects an evolving dimension driven by human needs, production techniques, farming systems, and the growth of agricultural markets. Academic and cultural debates on rural development highlight the joint evolution of agriculture with other economic activities in developed economies. Different approaches, including an eco-compatible classification based on natural resources, have been proposed. Attitudinal Land Classifications are introduced as a knowledge tool for decision-making at different observational scales. The Integrated research methodology for the evaluation of rural territories is also presented as a detailed, multi-temporal research approach, providing maps, statistical indicators, policy assessments, and matrices of territorial potential and constraint factors. At the municipal level, policies aimed at enhancing the agricultural vocation of territories, stimulating local awareness of ecocompatible rural development, and implementing regulatory actions in collaboration with social partners and territorial stakeholders. The work addresses key issues, including the local community response to policies, confidence in natural resources, their perceptions of constraints or opportunities, and the desired type of development aimed at advising the scientific community and associations on the best policies for the protection of the territory
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
River basins and rural districts: toward a regional planning for Italian watersheds with a broader European view
No full textn spite of the extensive regulations on hydrogeological hazards and the widespread implementation of defence works, the natural fragility of the Italian territory constantly exposes this country to instability phenomena, occurring with regular frequency and causing significant damage to people, structures, and the environment, and compromising the balance of the territorial structure. Within this framework, this chapter presents a series of reflections on how the evolution of a territory due to anthropogenic impact, the increase in climatic variability, and land-use changes can accelerate or mitigate the effects of hydrological extremes. A disaster prevention system, including territorial redevelopment and rehabilitation interventions, should be encouraged not only for environmental protection, but also as an essential element of the country's sustainable socioeconomic development. In this context, an appropriate geographical reference unit is represented by the hydrographic basin, whose analysis is crucial to understanding its predisposition to the different types of instability. The basin also acquires the role of a territorial government unit, at whose scale mitigation measures and damage reduction efforts should be implemented to achieve a rational and coordinated use of the land and of its natural resources, water, and soil. Only an innovative management approach, implemented according to the guidelines suggested by scientific research on agroforestry ecosystems, can provide considerable and lasting benefits to land protection, and at least partially solve the problem of hydrogeological instability
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
