Public perception of air pollution sources across Europe
Full text linkAir pollution is one of the primary concerns of our society for its effect on human health and the environment. Among the policy measures that can be put in place to limit air pollutant emissions, end-of-pipe technologies and/or regulatory instruments may be implemented through legislative acts. Also, equally important are behavioural measures, requiring citizens' active involvement. The success of any measure to limit pollutant emissions requires the acceptance by the citizens that, in turn, implies a correct perception of the main pollutant emission drivers. We present here the comparison between the public perception of air pollution sources and the real-world situation through a survey carried out in seven European countries and involving 16 101 respondents. Our study shows a dramatic underestimation of the contribution of the agri-food sector to air pollution. This result is common to all respondents in the seven countries examined and only to a small extent depends on gender, age and socio-economic status of the respondents
The politics of transnational municipalism for sustainable development in the European Union. An urban analysis
Full text linkThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University LondonIn the last thirty years, European local authorities have played a pro-active role in the realm of sustainable development, taking part in several European initiatives and projects and setting up municipal networks. The latter, which connect cities scattered across Member States, may focus on specific environmental issues, such as sustainable mobility or energy, or include sustainable development in a wide range of policy priorities. These socio-ecological urban networks (hereafter SEUNs) have attracted growing academic attention. However, the bulk of the literature is located within Geography and Urban Studies, and it is more focused on the structure of the networks, the process of decision-making, and the policy outcomes than on the drivers of cities’ membership of SEUNs. Within this debate, the contribution of Political Science has been scant, and the political and economic drivers of cities’ engagement in European socio-ecological municipal networks have been overlooked. Understanding why local governments decide to participate in these networks is important for two main reasons: firstly, it contributes to shedding light on how contemporary local political elites govern cities within the European context; secondly, it allows us to understand why European cooperation for sustainable development has become a dominant discourse in urban politics. Conversely, this thesis adopts an urban approach to isolate the urban-level economic, political and institutional factors that impact on local authorities’ participations in European socio-ecological urban networks. Using a nested research design that combines a quantitative and qualitative analysis, the thesis seeks to shed light on the factors and motivations underlying the choice of cities to participate in European networks for sustainability. The results show that cities’ European commitment to sustainable development is part of a broad strategy to achieve urban regeneration. Therefore, participation in SEUNs is not necessarily motivated by environmental preoccupations but is functional to achieve economic and political objectives.College of Business Arts and Social Science, Brunel University Londo
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
The local dimension in the degrowth literature. A critical discussion
Full text linkDegrowth is establishing itself as a theory within the ecological and post-development scholarship. At the core of degrowth is a local-centric perspective, whereby small urban agglomerations are considered as the key actors of the political and economic system of an imagined post-consumerist and post-capitalist society. Degrowth proponents thus argue that the fundamental steps to achieve a truly democratic, socially just and ecological society should be taken at local level. However, in the degrowth theory a thorough debate about why the local level would be the most suitable spatial units to achieve degrowth is scarce. The importance of the small urban size appears to be axiomatic, rather than supported by substantive arguments. By engaging with non-mainstream strands of green political thought, this paper critically reflects upon the local-centred perspective at the core of the degrowth theory, identifying its main practical and theoretical shortcomings
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
‘All cities are equal, but some are more equal than others’:Policy mobility and asymmetric relations in inter-urban networks for sustainability
Full text linkKnowledge sharing is deemed an important function of transnational municipal networks. However, in the literature on these organisations, a critical discussion of the implications of this process is scant. This article unpacks the mechanisms regulating learning, and examines the cognitive and relational dynamics of knowledge exchange within socio-ecological urban networks. By analysing the experience of a small group of European post-industrial second cities in socio-ecological urban networks, this article shows that network members exchange ideas and practices to tackle urban regeneration issues. The data suggest that, despite touted as a peer-to-peer practice, knowledge sharing reinforces asymmetrical relationships among network members, enabling the ‘soft domination’ of more advanced cities over less successful ones
