Harmful algal blooms: implications for human health and economic valuation
Get PDFAlgal blooms may have a number of harmful socio-economic impacts. The present study reviews the international literature on toxic algal blooms, with a special emphasis on available studies on the ecotoxicology of toxic algal blooms and the economic valuation of their impacts

Miljødatabaser og IT-applikasjoner i tiltaksanalyse under EUs. Rammedirektiv for Vann - metodiske utfordringer for NIVA
Get PDFRapporten går gjennom kravene EUs Rammedirektiv for Vann (Vanndirektivet) stiller til tiltaksanalyser, og diskuterer hvilke krav dette igjen stiller til miljødatabaser og vannfaglige IT-applikasjoner som brukes ved NIVA. Kostnadseffektivitets- og nytte-kostnadsanalyser av tiltak under Vanndirektivet stiller krav til integrert modellering av tiltakseffekt gjennom vannstrengen. Ideelt sett bør tiltakseffekt kunne modelleres med minst like stor sted- og tidsmessig oppløsning som brukes i økonomiske verdsettingsundersøkelser. Grunnet manglende oversiktelighet og tilgjengelighet av NIVAs mange miljødatabaser, lite "standard" bruk av vannfaglig modellverktøy i konsulent-oppdrag, og liten erfaring med integrering av disse verktøyene med økonomiske analyser av tiltak, er NIVA bare delvis klar til å ta på seg mange og simultane tiltaksanalyser som må gjennomføres under Vanndirektivet. En standardisering av "modell-familier" eller "verktøyskasser" i tiltaksanalyser ville også bidra til en bedre markedsføring av NIVAs kompetanse i Norge og utlandet

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
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
Assessing Economic Benefits of Good Ecological Status in Lakes under the EU Water Framework Directive. Case study report. Norway
Get PDFAn internet survey was conducted on 1113 households in Østfold County and southern municipalities of Akershus County in the summer of 2008. The survey focused on households’ recreational use of water bodies and their willingness to pay for improvements in lake ecological status. The main objective of the study was to evaluate at what distance from improved lakes, households willingness to pay falls to zero. This is key to correctly determining how large a population has benefits from measures under the Water Framework Directive, and making correct estimates of total benefits of a programme of measures. Valuation methods aimed at capturing recreational use values and also non-use values. The largest lakes in Østfold in three different catchments (Morsa, Glomma and Halden) were considered, Alternative valuation methods are compared for two lakes in particular in this report (Vestre Vansjø and Storefjorden). The study was the Norwegian case study for the EUFP6 AQUAMONEY research project
