    The Workshop on the operational use of Food Web indicators and information (WKFoodWeb), held in Copenhagen from February 19–21, 2024, focused on the future integration of food web information into ICES advice and progress towards Ecosystem-Based Management and Ecosystem-Based Fisheries Management (EBFM). Key iscussions focused on how food web and ecosystem information could compliment the existing ICES advisory framework, including catch advice and Ecosystem Overviews. Invited presentations addressed ecosystem-informed scientific advice, the use of food web indicators, and the development and availability of food web models. Examples from academics, NGOs, and government advisors showcased how ICES might use food web indicators (such as feeding guild indicators and Ecological Network Analysis indicators) to deliver food web information to requesters which is consistent with their objectives under various policy commitments (e.g., Good Environmental Status; GES). Participants emphasised the need for standardised and accessible methods across ecoregions and ICES expert groups with improved data integration, stakeholder engagement, and transparent and robust communication of uncertainties. Breakout groups discussed options for the integration of food web information in advice, where and when needed, by means of pragmatic mechanisms for EBFM and the inclusion of more informative food web products in Ecosystem Overviews. The workshop concluded with actions and priorities focused on 1) synthesizing information and efforts regarding the development food web indicators across ICES expert groups, 2) developing and communicating options for ecosystem-informed fisheries advice, and 3) creating a roadmap for the systematic and transparent use of food web models within ICES

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

    We 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

    Identification of standard ecosystem evaluation criteria for the assessment of the Discard Mitigation Strategies

    Executive Summary Standard criteria and indicators to assess the most relevant effects of discards on MSFD descriptors are required to ensure that the evaluation of the Discard Mitigation Strategies suggested in DiscardLess focuses on aspects relevant to the Good Environmental Status. The descriptors considered in DiscardLess to evaluate whether the Discard Mitigation Strategies promote GES are: the descriptors D1 (biodiversity), D3 (commercial fish and shellfish), D4 (food web), D5 (eutrophication) and D6 (sea-floor integrity). DiscardLess uses a selection of the simulation models developed with Ecopath with Ecosim, OSMOSE, Atlantis, ISIS-Fish, and StrathE2E to assess the outcomes of scenarios in different case studies based on standard criteria. In D1.2, DiscardLess defined the criteria and indicators to be used in determining the effects of discards on marine ecosystems. Indicators were defined for the following criteria: population abundance or biomass (D1), population demographic characteristics (D1), composition and relative proportions of ecosystem components (D1), fishing mortality (D3), spawning stock biomass (D3), proportion of fish larger than the mean size of maturity (D3), performance of key predator species using their production per unit biomass (D4), proportion of large fish (D4), abundance trends of functionally groups or species (D4), nutrients concentration in the water column (D5), chlorophyll concentration in the water column (D5), dissolved oxygen changes and size of the area concerned (D5), and bottom trawling effort maps (D6). Discard Mitigation Strategies will be translated into scenarios and assessed by using projections. Resulting time series of criteria will be compared across strategies and to the baseline scenarios.This is DiscardLess Project Delliverable Report 1.2 towards Strategies for the gradual elimination of discards in European fisheries
