Sustainability Assessment of Urban Systems
No full textOur world is becoming more and more urban. Already, about 50% of the population lives in cities posing new challenges for sustainable development. What does sustainability mean in the context of living in a city? This book provides guidelines for sustainability assessment of urban systems to be used by experts and policy makers alike. We integrate theory and methods around sustainability assessment with concepts of systems science. We present and discuss already employed concepts of sustainability assessment and new ways of conceptualizing sustainability assessment issues in urban settings around the world. The book highlights the need to find models and solutions in order to design the sustainable cities of the future in light of the complexity of urban social life. It further presents different aspects of urban sustainability from energy to housing, to mobility and health covering social, economic and environmental aspects.HERU

No full textHow Values Play into Sustainability Assessments: Challenges and a Possible Way Forward
No full textAny sustainability assessment uses some notion of sustainability as a reference. It is increasingly acknowledged that sustainability is a contested concept and that its different definitions are rooted in different values. Accordingly, researchers have started to develop approaches for producing knowledge in a context of diverging values. However, little attention has been paid to these values and to how they play into sustainability assessments. In this chapter, we address this question in three parts. First, we show how different ethical positions and worldviews enter notions of sustainability and shape the solution spaces for sustainability issues which are taken into consideration. Secondly, we present different stances on how the scientific method should address the presence of values and show how they can be traced back to different values about what good science is. Thirdly, we show that values are historically constructed and shaped by the socioeconomic, sociotechnological, and socioecological order and at the same time contribute to reproducing it. We also show that this process risks leading to a prevalence of notions of sustainability that reproduce the very dynamics at the origin of the sustainability problem at hand. We conclude the chapter with recommendations for how this challenge could be overcome.HERU
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
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
