Aims, Challenges and Progress of the Hydrological Ensemble Prediction Experiment (HEPEX) - Following the 3rd HEPEX Workshop Held in Stresa 27-29th June 2007
No full textOver the past several years users of meteorological weather forecasting data have begun to realize the benefit of quantifying the uncertainty associated with forecasts rather than relying on single value forecasts for the most probable scenario. At the same time, hydrologists and water managers have begun to explore the potential benefit of ensemble prediction systems for hydrological applications. The Hydrologic Ensemble Prediction EXperiment (HEPEX), established in 2004, is an international project that aims to foster the development of advanced probabilistic hydrologic forecast techniques and of corresponding decision making tools. During the past 3 years, HEPEX has provided discussion opportunities for hydrological and meteorological scientists involved in the development, testing and operational management of forecasting systems, and end-users. During the third international workshop on HEPEX, organized in Stresa, Italy, on 27-29th June 2007, results from previously defined test-bed projects were presented, some key scientific questions were discussed, and some additional test-bed projects were proposed. This manuscript summarizes the project status after the conclusion of the 3rd HEPEX WS.JRC.H.7 - Land management and natural hazard
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
