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
Copy but don’t paste : From student-led to collaborative action for sustainability in higher education
No full textThe Center for Environment and Development Studies (Cemus) is a student-initiated and primarily student-led university center, straddling the two universities (Uppsala University and the Swedish University of Agricultural Sciences) inthe town of Uppsala, Sweden.Since its inception in the early 1990s, the center has initiated and expanded the space for transdisciplinary, collaborative higher education as well as research and collaboration that transcends traditional academic disciplines and boundaries between academia and society at large. Based on the idea that the young people of today are key stakeholders of the future, Cemus has for over two decades acted as a platform for students to shape their own education and future, and has also become a creative and international meeting place for the larger university community to discuss and grapple with some of the most pressing sustainability challenges of our time.In the last few years Cemus has had an increased collaboration with a number of new partners, both within and outside the university, nationally and internationally. Lasting 3 years, and spanning a range of activities, Action for Sustainability in Higher Education in the Nordic Countries (ActSHEN) has been the most comprehensive of these international collaborations that Cemus has been involved in. This paper explores the impact and value of ActSHEN upon activities at Cemus, as well as, the role of Cemus in the ActSHEN project, based on reflections from students and staff that participated in ActSHEN.</p
Perilous times : Carbon budgets and the cosmopolitics of climate mitigation
No full textIncreasingly emphatic warnings from scientists about the dire consequences of global climate change has contributed to the establishment of an international governance regime and a world-wide proliferation of policies and actions that in different ways attempt to mitigate the problem. However, the decades that have passed since the publication of the first IPCC report in 1990, have been beset by an inexorable rise in global greenhouse gas emissions, with more fossil carbon anthropogenically released into the atmosphere than previously throughout history. With the cumulative nature of emissions and rapidly dwindling size of global carbon budgets, achieving mitigation at rates concomitant with the Paris Agreement becomes increasingly urgent and challenging as time passes. This thesis explores the imaginaries, temporalities and practices involved in historical and ongoing efforts to mitigate climate change at global as well as national, regional and local levels in Sweden. The climate policy framework of Sweden is first analysed and found to fall far short of delivering on the temperature and equity commitments of the Paris Agreement. Factors contributing to the absence of a globally proportionate response are then reviewed, where a key impediment to mitigation is found to reside in various forms of power – from a dogmatic political-economic hegemony and influential vested interests to narrow techno-economic mindsets and ideologies of control. Attention is then shifted to the Swedish counties of Uppsala and Gotland, where the temporalities of urgency and acceleration accompanying emerging (net) zero carbon imaginaries are seen to have the paradoxical effect of raising fundamental and difficult questions for regional planning while also risking to undermine its capacity for envisioning alternative futures. Moving closer to the ground, a series of walking interviews reveals everyday possibilities for escaping ineffective and extractive responses to the climate crisis amongst practitioners involved in the ongoing urban development of Ulleråker, in the city of Uppsala. The findings of this thesis collectively suggest that our times are perilous in at least three ways: In the escalating effects of the climate crisis, in the responses conceived to address the problem, and in the forms of attention that the accompanying temporalities give rise to
Communal Polyethylene Biogas Systems : Experiences from on-farm research in rural West Java
No full textIn Lembang, a farming community on western Java, family-sized, plug-flow, polyethylene biogas systems fed with cow dung, are being used as an integrated solution to issues related to energy, agriculture and waste management. Through simple, on-farm research and observation, a number of key problems have been addressed and improvements made to the design. Due to the large supply of cow dung in the area, and the potential to spread the benefits of the technology beyond the homes of dairy farmers, the feasibility of developing a communal, polyethylene biogas system for several households, has been investigated. Experiments on small model-digesters were combined with observations of full-scale biogas systems in use. Measurement equipment and techniques were constructed and developed, in order to measure biogas production and other relevant process parameters. Results indicate that a communal system can be an appropriate choice, but only under a certain set of circumstances
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
