Legislative Foundations: Exploring Land Take Laws and Urban Regeneration Policies in Italy and Europe
No full textSoil is now a central issue on the European as well as the national political agenda, as it represents a fundamental ecosystem for human survival on the planet. Today, more than ever, its protection and proper use in various contexts (agricultural, natural, urban) require stringent policies that can be implemented immediately. The difficult reversibility of urban transformations is the main threat to the ecosystem integrity of soil. Starting from this statement, the main objective of the proposed work is to analyze how the main European countries (Italy, France, Germany, and Spain) are addressing the issue of the goal of zero net land take by 2050 by examining the current laws and strategies. The results highlight how the regulatory aspect plays a key role in managing the phenomenon and how the absence of a national framework law can generate strong distortions and different interpretations of the soil ecosystem. The analysis of the Nature Restoration Law, adopted by the European Commission in July 2023, enables us to assess whether the regulations and measures adopted by the major European countries align with the European Union’s trends. Through a comparative perspective, the study aims to contribute to a comprehensive understanding of sustainable development practices and provide valuable insights for policymakers, urban planners, and academics
Investigation of the redox behavior of double perovskite PrBaMn2O5+δ
No full textA multi analytical approach (in situ X-ray diffractometry, XRD, temperature programmed reduction TPR, thermogravimetry TGA) was used to deeply study the phase transition between the Pr0.5Ba0.5MnO3-δ (m-PBM) and the double layered perovskite PrBaMn2O5+δ (l-PBM). m-PBM sample was prepared by an autocombustion based citrate procedure and exposed to consecutive reduction and oxidation cycles at high temperature to understand the effect of oxidizing and reducing atmospheres on structural changes and stabilization of the layered double perovskite. XRD analysis showed the existence of a pseudo cubic structure (c-PBM), which is formed from the direct oxidation of l-PBM. TPR results confirmed the c-PBM to l-PBM reversibility to the redox processes, and the TGA characterization showed a fast transition between l-PBM to c- PBM. The oxidation of l-PBM to c-PBM seems pivotal for the stabilization of the layered reduced structure. The results are discussed in the perspective to develop versatile electrodes for SOEC/SOFC applications
The importance of urban regeneration actions: European and Italian legislative framework analysis
Full text linkThis work focuses on the measures put in place to stem and contain the phenomenon of
urbanization and soil sealing in Europe and highlights the measures that various European coun-
tries have taken to curb land consumption and promote urban regeneration. The focus is on Italy,
where the lack of a national law on land consumption and inconsistent regional regulations pose a
hard challenge. The study compares urban regeneration laws in the main European countries and
Italy, by analyzing best practices and conducting an analysis of the "Nature Restoration Law"
adopted by the European Commission in July 2023. The research emphasizes the necessity of adopt-
ing a comprehensive strategy to address urbanization challenges, as urban regeneration efforts can
enhance city sustainability and resilience through improved provision of ecosystem services
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

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
