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
Urban political ecology III
No full text Given the ongoing importance of nature in the city, better grappling with the gendering and queering of urban political ecology offers important insights that collectively provides important political possibilities. The cross-currents of feminist political ecology, queer ecology, queer urbanism and more general contributions to feminist urban geography create critical opportunities to expand UPE’s horizons toward more egalitarian and praxis-centered prospects. These intellectual threads in conversation with the broader Marxist roots of UPE, and other second-generation variants, including what I have previously called abolition ecology, combine to at once show the ongoing promises of heterodox UPE and at the same time contribute more broadly beyond the realm of UPE. </jats:p
Cooking up Non-violent Civil-disobedient Direct Action for the Hungry: 'Food Not Bombs' and the Resurgence of Radical Democracy in the US
No full textThis paper examines the efforts of one of the fastest-growing (anarchist) social movement groups in the world, 'Food Not Bombs' (FNB), to redefine urban anti-hunger politics in the US. The aim is to understand how FNB contests the politics and processes of poor people's containment through their efforts to develop new, decommodified modes of biopolitics. As it is central to their success, the paper focuses on how FNB uses non-violent civil-disobedient direct action to provide an alternative grassroots response to the destructive market-driven imperatives of neo-liberal capitalism. The case of FNB provides an example of the continued potential for mutual aid and co-operativism in the city and does so against the backdrop of growing injustices within an ever-globalising world. Ultimately, the paper shows that FNB offers an example of the kinds of resistance necessary to secure the most fundamentally inherent right to the city, which is the right to eat and survive in the city.
Green urban political ecologies: toward a better understanding of inner-city environmental change
No full textThis research uses a Marxist urban political ecology framework to link processes of urban environmental metabolization explicitly to the consumption fund of the built environment. Instead of reinventing the wheel, I argue in this paper that Marxist notions of metabolism are ideal for investigating urban environmental change and the production of uneven urban environments. In so doing, I argue that despite the embeddedness of Harvey’s circuits of capital within urban political economy, these connected notions still have a great deal to offer regarding better understanding relations between consumption and metabolization of urban environments. From this theoretical perspective, I investigate urban socionatural metabolization as a function of the broader socioeconomic processes related to urban restructuring within the USA between 1962 and 1993 in the Indianapolis inner-city urban forest. The research examines the relations between changes in household income and changes in urban forest canopy cover. The results of the research indicate that there was a significant decline over time in the Indianapolis urban forest canopy and that median household was related to these changes, thus demonstrating a concrete example of urban environmental metabolization.
