Air Pollution XXII: Twenty Second Conference on Modelling, Monitoring and Management of Air Pollution
No full textAir Pollution XXIV
No full textIn these proceedings of the 24th International Conference on Modelling, Monitoring and Management of Air Pollution, international academics and air pollution practitioners contribute to the evolving understanding of the science and policy contexts of air pollution.The management of air pollution is one of the most challenging problems facing the international community. A particular strength of the series has been the attention given to regulatory and, market solutions to air pollution management. The Air Pollution series of conferences has consistently acknowledged that science remains the key to identifying the nature and scale of air pollution impacts and reaffirmed that science is essential in the formulation of policy relevant information for regulatory decision making. The conference series also acknowledged, at a very early stage, that science alone will not improve a polluted atmosphere. The scientific knowledge derived from well-designed studies needs to be allied with further technical and economic studies in order to ensure cost effective and efficient mitigation. In turn, the science, technology and economic outcomes are necessary but not sufficient
Education for sustainable development: Guidance for UK higher education providers
No full textThis guidance is intended to assist staff in UK higher education institutions seeking to incorporate education for sustainable development within the curricula. It has been produced by an expert group drawn from across the sector with the aim of supporting students from any discipline to acquire knowledge, understanding and skills relevant to sustainable development
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
Microbial and endotoxin emission from composting facilities: characterisation of release and dispersal patterns
No full textThe potential risk to human health posed by exposure to bioaerosols released from composting is an important issue. Further growth in the number of composting facilities in the UK is anticipated as biodegradable waste is diverted from landfill. To date, studies of bioaerosol emission from composting have focussed on culturable bioaerosols. This paper describes both culturable bioaerosol and endotoxin release and dispersal from two large green waste composting facilities in the UK. Aspergillus fumigatus, actinomycetes, Gram-negative bacteria, and endotoxins were simultaneously and repeatedly sampled to describe the release and dispersal from these sites. Meteorological and site operational observations were recorded, allowing analysis of factors influencing bioaerosol release and dispersal. The highest measured concentrations of bioaerosols were associated with composting activities such as shredding and turning. Between release and 50-80m downwind bioaerosol concentrations reduced by 80-90%. An unexpected second peak was detected 100-150m downwind from source at both sites. Endotoxin dispersal patterns were site specific and showed some differences to dispersal patterns of culturable microorganisms. © 2009 WIT Press
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
