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
Aanpak wateroverlast in polders op basis van risicobeheer
No full textThe subject of this dissertation is flooding in lowland areas caused by intense precipitation. The probability of flooding will increase when we do not adapt our water systems. For example because of expected changes in climate and the consequences of subsidence, sea level rise, and urbanization. While the probability of flooding will increase, the degree of acceptance by Dutch society of possible flooding is decreasing. Society expects from the water manager that it may count on "dry feet". Within this context the task of water boards is to determine whether water systems are still suitable to provide sufficient protection against flooding. If not, the boards have to determine which improvements are necessary to raise the level of protection. However, nowadays more scenarios need to be incorporated in the analysis. This leads to the question whether the classic methods most commonly applied need to be adjusted or not. The thesis of this dissertation is that assessing the urgency to adapt an existing water system needs to be based on risk analysis. Next, identification of improvements should be based on cost/benefit analysis, because (1) this approach enables the specific local circumstances to be taken into account better than the present standards do; (2) it provides insights in the consequences of all kinds of future scenarios in a unit everyone can understand: money; and (3) the analysis supports a more transparent decision making process since it forces decision-makers to make explicit why it is attractive to take certain measures.Civil Engineering and Geoscience
