Topics in Environmental Software Systems
No full textPart 1: Keynotes and Context ArticlesInternational audienceEnvironmental software systems (ESS) are software systems supporting activities of environmental protection, environmental management, environmental policy and environmental sciences. ESS often overlap with adjacent application fields like security, agriculture, health or climate change. The ISESS conference series is one of several overlapping events which are devoted to environmental modelling and software systems. ISESS is probably the one international event which has the strongest focus on the software angle.This paper gives a historic perspective of 20 years of ISESS conferences. Starting with a historic review of the development of the field named “environmental software systems”, it puts the ISESS conference into the greater perspective of similar activities. Using the original materials the paper identifies typical themes subsumed under ESS, and highlights typical topics for the time.The paper is the only existing complete collection of activities of the IFIP working group 5.11 “Computers and Environment”. Material of all events, ISESS conferences as well as co-organised workshops has been collected in one central place and will also to be kept up to date in the future

No full textAn Information Model for a Water Information Platform
No full textPart 2: Information Systems, Information Modelling and SemanticsInternational audienceSharing of open government data is amongst other reasons hindered by incompatibility of data models in different data collections. Only a few areas in the environmental domain have progressed towards commonly used data models. The purpose of this paper is to share with the community a data model which is used in a spatial information platform being built for the purpose of sharing open government data in the domain of water sciences. The objective when building the information model was not to be restricted to one and only one (meta)data standard. The information model therefore uses several standards and extension mechanisms: the ISO19000 series, the Comprehensive Knowledge Archive Network (CKAN), dynamic tag extension and dynamic content extension. The CKAN domain model can also be mapped to semantic-web-compatible standards like Dublin Core and the Data Catalogue Vocabulary of the World Wide Web Consortium
A Software Package for Automated Partitioning of Catchments
No full textPart 7: Analytics and VisualizationInternational audienceThis paper reports about a software package which has been developed to automatically partition hydrological networks (catchments) into clusters of similar size. Such clustering is useful for parallel simulation of catchments on distributed computing systems and is typically based on heuristic graph algorithms.There have been a few approaches to automatically partition catchments, but literature research indicates that there seems to be no systematic investigation of the usefulness of different graph algorithms for catchment partitioning over a reasonable number of real world data sets. Our study aims at making a step in this direction.The paper describes the software package, which has been implemented in Java, its pluggable architecture, and initial experiments using the European catchment dataset ECRINS. The paper presents work in progress
Vision and Requirements of Scenario-Driven Environmental Decision Support Systems Supporting Automation for End Users
No full textPart 2: eEnvironment and Cross-Border Services in Digital Agenda for EuropeInternational audienceThis paper discusses the vision and requirements of a highly interactive workbench which supports decision makers using distributed resources including models as automated components of an integrated environmental decision support system. The concepts discussed are results of the SUDPLAN project, an EU FP7 project which aims at developing advanced tools for climate change adaptation for city planners and city managers. To this end, SUDPLAN incorporates access to climate change models and model results as an important common service. This paper provides an overview of SUDPLAN, with special emphasis on the highly interactive Scenario Management System. It also includes an overview of the user requirements derived through a user-centred design process engaging highly diverse user representatives of four pilot application cities
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
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
