Cambiamento climatico e rischio. Proposte per una didattica geografica
No full textIl volume nasce con l’obiettivo di dare un contributo e aprire a nuove riflessioni nell’insegnamento geografico, sia attraverso elementi teorici sia attraverso la proposta di attività pratiche, che mirano ad affrontare in modo sistematico i temi del rischio e del cambiamento climatico. Partendo dall’esperienza fatta in occasione del 61° Congresso Nazionale AIIG (Termoli, 4-8 ottobre 2018) e da successivi momenti formativi promossi da alcune AIIG locali, è stato possibile testare e ragionare sul ruolo che la geografia può avere nella diffusione di queste tematiche, e sulla responsabilità che le deriva in quanto disciplina di sintesi. I temi in oggetto, infatti, sono spesso ai margini dell’insegnamento e dell’attenzione geografica, nonostante rivestano un ruolo cardine nella comprensione dei territori e nell’elaborazione/promozione delle politiche economiche, sociali e ambientali. L’idea di focalizzare l’attenzione di questo volume su un argomento specifico nasce dalla consapevolezza che ora più che mai appare necessario riconoscere la geografia del rischio come ambito di ricerca e riflessione portante della geografia italiana. Al fine di mettere a disposizione uno strumento il più esauriente possibile da proporre alle scuole e agli educatori, è stato utile e necessario guardare non solo a geografi ma più in generale ad operatori del territorio che quotidianamente si rapportano con queste tematiche. Le esperienze e le attività proposte, pertanto, provengono da attori diversi (protezione civile, ong, università) con l’obiettivo di fornire un primo strumento di lavoro, che possa avere dei risvolti pratici oltre che di stimolo. In particolare, è stato dato spazio a metodologie di lavoro differenti che guardassero a diverse tipologie di rischio (cambiamenti climatici, terremoti, multi-hazard, ecc.) capaci di offrire alcuni primi spunti di riflessione nonché esempi replicabili e ulteriormente sviluppabili da insegnanti di diverso ordine e grado
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
Wild Encounters. Toward a reinterpretation of urban green policies by the rivers in Rome and Cagliari
No full textThis chapter critically examines urban green policies and reveals underlying agendas of control and land value extraction. Two case studies – Quartucciu (a small town near Cagliari) and Rome – highlight how green initiatives often prioritize beautification and economic interests over environmental and social stewardship. In Quartucciu, a proposed linear park along the Is Cungiaus river reflects a neoliberal approach to urbanization, while in Rome, the transformation of the Tiber riverbanks represents control under the guise of ecological restoration. By embracing the concept of “wildness” this chapter challenges conventional notions of urban nature and highlights the complexities of interstitial spaces, where diverse socio-environmental practices resist commodification. Ultimately, this chapter calls for a reevaluation of urban green policies through the encounters with the spatial practices that still exist in these two contexts
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
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
