Future advances in UK marine fisheries policy: Integrated nexus management, technological advance, and shifting public opinion
Full text linkHaving left the European Union, the UK Fisheries Act (hereafter referred to as the Act) provides a framework that may advance sustainable marine resource management. This requires the bias towards social-economic concerns to be recognised, and greater emphasis to be placed on securing the natural capital to support fisheries. A Joint Fisheries Statement (JFS) to be published in 2022 by the UK’s devolved fisheries authorities will set out how the objectives of the Act will be achieved. While recognising the value of principles of the Act, this article challenges the current management framework in light of the wider challenges in fisheries practice. It argues for more emphasis on ecological and fisheries regeneration, and maximising societal benefits rather than yields. Three recommendations are provided: (1) an integrated and more holistic Fisheries-Energy-Environment Nexus resource management approach would better utilise systems thinking to optimise trade-offs and synergies between competing domains to achieve fisheries, conservation and other environmental goals (e.g. delivering the national net zero strategy); (2) the use of best available technologies as is reasonably practicable to monitor compliance and facilitate enforcement should be a regulatory requirement under the JFS; (3) the fisheries and marine conservation science community should work with other stakeholders to change the media narrative, public opinion, and political direction away from a “business-as-usual” model that risks long-term degradation of the marine fisheries resource
The future of marine fisheries management and conservation in the United Kingdom: lessons learnt from over 100 years of biased policy
Full text linkMarine wild-capture fisheries depend on the capacity of the ocean to provide a flow of harvestable resources to sustain the industry. Paradoxically, conventional fishing often undermines these resources by degrading the environment and overexploiting fish stocks. Many UK fisheries have declined for over a century due to a biased focus on their social-economic value and lack of recognition that they are social-ecological systems and need to be managed as such. With the UK’s recent transition to an independent coastal state, the Fisheries Act (2020) and associated Joint Fisheries Statement provide an opportunity to correct this. Focusing on the ecological foundations, a more sustainable future for UK fisheries may be achieved by: (1) implementing a conservative quota setting system based on Maximum Sustainable Yield (MSY), defined as that which would occur when the biomass of a population of the target species is at 50% of that estimated at carrying capacity, to set catch limits rather than targets. The biomass of fish stocks should be allowed to regenerate to a minimum of 120% of that which will achieve MSY to provide a buffer against the uncertainty in ecological response to climate change. (2) Fishing capacity should be reduced while redistributing a greater share of the quota to sectors of the fleet that are demonstrably more sustainable; recognising that short term compensation may be required by some to mitigate the impacts of displaced activity until the benefits of stock recovery are realised. (3) Greater restrictions should be applied to ensure the most damaging fishing techniques (e.g. bottom trawling and dredging) are prohibited as appropriate in the network of marine protected areas. Protection should be enforced to promote the regeneration of degraded habitats and restoration of fish populations to help achieve the objectives as set out in the Act
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
The importance of rebuilding trust in fisheries governance in post-Brexit England
Full text linkThe sustainable management of common pool resources, like fisheries, relies heavily on trust and reciprocity between managers and stakeholders (fishers). The UK Fisheries Act of 2020 and the Joint Fisheries Statement of 2022 seek to reinvent post-Brexit fisheries governance and the economic and environmental sustainability of the sector. Management of the fisheries sector through Fisheries Management Plans (FMPs) is still under development but changes in governance arrangements are likely to significantly impact fishers’ livelihoods. This highlights a need for improved collaboration between fishers and the governing institutions. Using a novel survey design, representatives of the English fisheries sector were surveyed to capture their level of different forms of trust (rational, affinitive, system-based) towards national and regional governing institutions. Overall, low levels of trust were found, although regional institutions (i.e., Inshore Fisheries and Conservation Authorities) were more trusted than national institutions (i.e., Department for Environment Food and Rural Affairs and Marine Management Organisation). Exploring different forms of trust revealed nuance between the institutions and distinctive regional differences. To build on this, interviews were conducted revealing feelings of apathy and conflict towards the governing institutions rather than inclination towards collaborating. Trust has a role in fostering more resilient fisheries management and fishers discussed the need for sustained institutional efforts to rebuild trust post-Brexit through greater transparency, face-to-face interaction, and meaningful consultation. Our research also reveals that FMPs will need to factor in geographical differences and that current institutions will need to work more collaboratively in order to foster local adaptive management
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
No full textWe 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
