Sviluppo socio-economico delle Alpi nel terzo millennio: una minaccia per le risorse naturali?
Full text linkNeoliberal urbanism and disaster vulnerability on the Chilean central coast
No full textThis paper examines the links between neoliberal urbanism and disaster vulnerability in Cartagena, a town on the Chilean central coast. In recent decades, this area has been transformed by speculative urban development, resulting in environmental damage and increased socio-economic segregation. We adopt a political ecology perspective to consider how these changes interact with disaster risk, drawing on ten interviews with representatives of local community organisations, a collaborative mapping exercise and census data. We find that mass tourism and informal urban expansion contribute to environmental degradation, as well as infrastructural and economic fragility, leading to increased risks for residents and tourists alike. We position our case study against the critiques of vulnerability leveraged by several critical geographers, who have come to see the term as depoliticising. While sympathising with these critiques, we argue for the usefulness of vulnerability analyses combining political ecology approaches to the study of human-nature relations and insight from critical urban studies on issues such as neoliberal planning policies, extractivism, urban informality and touristification. Articulated in these terms, vulnerability can be usefully mobilised to push for substantive policy change
Collective mapping as a methodology for participatory, disaster-responsive urban planning: lessons from Chile
No full textCollective mapping (CM) emerged in the Global South as a tool to embed local
perspectives into territorial governance, particularly addressing issues of land use and
indigenous land rights. In the last decade, several disaster risk reduction (DRR) projects
have adopted CM methodologies, recognizing the importance of community participation
in this area. So far, however, such projects remain isolated instances, scarcely integrated
into formal decision-making mechanisms. Drawing on our research experience in Chile,
this contribution argues for the usefulness of CM as a participatory methodology for the
study of disaster risk in support of disaster-responsive urban planning. Since existing
territorial planning mechanisms tend to overlook the social roots of disasters, they often
result in increased risks for vulnerable, low income communities. CM can mitigate these
risks by complementing technical information about natural hazards with local
knowledge, legitimizing local claims and fostering community-driven processes of
regeneration of the built environment. Thus, it can play an important role in supporting
innovative forms of local engagement and more inclusive spatial decision-making that
will strengthen urban resilience within a holistic and democratic DRR framework

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
