    The City as a Commons

    As rapid urbanization intensifies around the world, so do contestations over how city space is utilized and for whose benefit urban revitalization is undertaken. The most prominent sites of this contestation are efforts by city residents to claim important urban goods—open squares, parks, abandoned or underutilized buildings, vacant lots, cultural institutions, streets and other urban infrastructure—as collective, or shared, resources of urban communities. The assertion of a common stake or interest in resources shared with others is a way of resisting the privatization and/or commodification of these resources. We situate these claims within an emerging “urban commons” framework embraced by progressive reformers and scholars across multiple disciplines. The urban commons framework has the potential to provide a discourse, and set of tools, for the development of revitalized and inclusive cities. Yet, scholars have failed to fully develop the concept of the “urban commons,” limiting its utility to policymakers. In this Article, we offer a pluralistic account of the urban commons, including the idea of the city itself as a commons. We find that, as a descriptive matter, the characteristics of some shared urban resources mimic open-access, depletable resources that require a governance or management regime to protect them in a congested and rivalrous urban environment. For other kinds of resources in dispute, the language and framework of the commons operates as a normative claim to open up access of an otherwise closed or limited access good. This latter claim resonates with the social obligation norm in property law identified by progressive property scholars and reflected in some doctrines that recognize that private ownership rights must sometimes yield to the common good or community interest. Ultimately, however, the urban commons framework is more than a legal tool to make proprietary claims on particular urban goods and resources. Rather, we argue that the utility of the commons framework is to raise the question of how best to manage, or govern, shared or common resources. The literature on the commons suggests alternatives beyond privatization of common resources or monopolistic public regulatory control over them. We propose that the collaborative and polycentric governance strategies already being employed to manage some natural and urban common resources can be scaled up to the city level to guide decisions about how city space and common goods are used, who has access to them, and how they are shared among a diverse population. We explore what it might look like to manage the city as a commons by describing two evolving models of what we call “urban collaborative governance”: the sharing city and the collaborative city

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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
