Huwelijk tussen natte waterbouw en ecologie
No full textDe Houtribdijk strekt zich uit tussen Lelystad en Enkhuizen. Wie over de weg tussen beide steden reist kan aan de Markermeerkant moerasachtig land ontwaren – kleine experimenten, die de voorboden zijn van grote ingrepen. Rijkswaterstaat experimenteert er met een omvangrijk 'wetland'
Ecodynamic design as a boundary object
No full textConsensus in Dutch society is that the existing coastal defence regime is not sustainable. Adaptation is not only a technical challenge, but affects elements like ecology, cultural heritage, recreation, urban development, making the issue complex both from a political and from a scientific point of view. And innovations must cope with the actual system of human beliefs, values and knowledges which constitute the old coastal management regime. One possible new regime is ecodynamic design. This is an approach using interactions between ecological processes and human interventions to create new coastal structures. The Building with Nature innovation program is implementing ecodynamic experiments along the Dutch coast. One of these is an experiment along the Frisian IJsselmeer coast in the Netherlands. Participating actors (governments, NGO’s, private partners) frame it as an adaptive action, potentially providing new flood defence methods to the region. The aim of this paper is to explore the role this Building with Nature experiment plays in the interactions between actors with different perspectives and how the experiment influences collaborative learning. This case is analysed using the concept of boundary objects
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Implementing Building with Nature in Complex Governance Situations
No full textTwo governance aspects of modern coastal engineering which seem to be of importance to many coastal projects all over the world are considered here. Reflections on these two aspects are related to the context in which projects take place. The first is the fragmentation of decision-making and funding. The second aspect is the growing sense of uncertainty actors experience as a result of the longer time horizons of projects and as a consequence of the integration of a growing number of functions to be served by the projects (including ecological ones). The question is: how to deal with this uncertainty? The issue of uncertainties inherent to “building with nature” is of special interest to projects and of relevance to governance
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
