Waste management and circular economy: Building a CGE framework
Full text linkReuse, recycling and use of bio waste may contribute to a more sustainable bio economy. To analyse the impact of reuse and recycling can have on the bio economy and the economy as a whole, municipal solid waste generation needs to be included in a CGE framework. In this paper we focussed on developing the methodology to include a waste management system in a CGE modelling framework and on building a database to run the new waste module within the global CGE model MAGNET. It includes introducing municipal solid waste generated by households and various options of dealing with waste by including new waste treatment sectors like landfills, waste to energy, recycling and composting sectors. Recycled materials like glass, paper, compost and biomass are generated and used as a substitute for virgin materials in the relevant sectors. In the developed system there is now a direct link between waste and bio-economic sectors in the model, thus making studies analysing circular economy feasible

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

Capital Utilization and investment Decisions: A Case Study for the Netherlands
Full text linkIn this paper a data envelopment model is presented to evaluate short term investment decisions in the Dutch beam trawl and demersal fleet. We investigated how short run profit drives investment decisions and how a data envelopment analysis can be used to show what the optimal level of capital use is and how investment in variable and fixed inputs can optimize the output of the sector. The degree of capital utilization can be seen as a measure of whether firms should invest or disinvest in their capital assets. Capital utilization also measures to which extent idle and excess capacity is present in a firm. Differences in capital utilization mainly depend on the degree in which a firm can adjust fixed capital in the short run. It therefore should be a key economic parameter to evaluate the performance of a sector. We measured the physical capital utilization for the Dutch beam trawl and demersal fleet for 2005 and decomposed the capacity utilization into technical efficiency, economic capital utilization and optimal capacity idleness. Furthermore we illustrated how the economic capacity measure can be used to predict investment decisions in the fleet. Results show that economic capital utilization inefficiency is on average 13%, which indicates that landings could have been 13% higher then they were if the fleet operated 100% efficiently. About 1% of the capacity utilization inefficiency is caused by idle/excess capacity. This very low percentage indicates that there are few indivisibilities in the input for the Dutch beam trawl and demersal fleet. Based on short term profit maximization it is clear that it is optimal to make as much use of the available capital as possible. The remaining 12% can be attributed to economic capacity inefficiency and technical inefficiency in the fleet. Vessels with a low capital utilization are more likely to disinvest than vessels with a high capital utilization. Vessels with a capital utilization that is higher than unity almost always will choose to invest.Keywords: Fishers Behavior, Fish and Aquaculture Sectors Development, Fisheries EconomicsKeywords: Fishers Behavior, Fish and Aquaculture Sectors Development, Fisheries Economic
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
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
