Improving the design and environmental effectiveness of woodlands for water Payments for Ecosystem Services
Full text linkThe EU Water Framework Directive aims to ensure restoration of Europe’s water bodies to “good ecological status” by 2027. Many Member States will struggle to meet this target, with around half of EU river catchments currently reporting below standard water quality. Diffuse pollution from agriculture represents a major pressure, affecting over 90% of river basins. Accumulating evidence shows that recent improvements to agricultural practices are benefiting water quality but in many cases will be insufficient to achieve WFD
objectives. There is growing support for land use change to help bridge the gap, with a particular focus on targeted tree planting to intercept and reduce the delivery of diffuse
pollutants to water. This form of integrated catchment management offers multiple benefits to society but a significant cost to landowners and managers. New economic instruments, in combination with spatial targeting, need to be developed to ensure cost effective solutions – including tree planting for water benefits - are realised. Payments for Ecosystem Services (PES) are flexible, incentive-based mechanisms that could play an important role in promoting land use change to deliver water quality targets. The PESFOR-W COST Action will consolidate learning from existing woodlands for water PES schemes in Europe and help standardize approaches to evaluating the environmental
effectiveness and cost-effectiveness of woodland measures. It will also create a European network through which PES schemes can be facilitated, extended and improved, for
example by incorporating other ecosystem services linking with aims of the wider forests carbon policy nexus
Business attitudes towards funding ecosystem services provided by urban forests
Full text linkUrban trees and woodlands provide a wide range of ecosystem services (ES) to society, for example, flood risk reduction, air purification, and moderation of urban heat islands. Despite this, local government budgets for tree planting and maintenance have declined in many cities throughout the world. Thus far, the academic literature has largely ignored whether businesses are willing to help fund urban forests and the ES they provide. Business financing via payments for ecosystem services (PES) within the urban realm is also under-researched and lacking in practice. This study aims to address these research gaps. Semi-structured interviews were carried out with 30 businesses of varying sizes and sectors, operating in Southampton, UK. Respondents thought a public-private partnership would be feasible, with a focus on voluntary payments towards enhancing air quality, reducing flood risk, and improving aesthetics. Respondents would prefer to choose from a list of location-specific, cost-effective, monitored projects to fund directly, for marketing and/or corporate social responsibility purposes. To facilitate business funding of urban forest-based ES, clear communication of the expected environmental benefits and a strong business case are required, drawing on the experience of similar initiatives. From our findings, we recommend the piloting and analysis of such PES schemes
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

On Demand-side Approaches to Solving the "Tragedy of High Prices" in Fisheries
Full text linkWhile overfishing frequently is explained in terms of «the Tragedy of the
Commons» model, it is argued that the economic causes of such long-run resource problems could be more accurately characterised in terms of a «Tragedy of High Prices» due to landings prices exceeding fishing costs at
the socially optimal level of resource use.
In tackling over-exploitation problems, the feasibility and relative efficiency of demand-side measures in attaining management objectives without necessitating introduction of other fishing rights is discussed. Distributional issues associated with using a market mechanism to allocate use rights and potential adoption of demand-side measures within a co-management framework are considered.
Despite apparently desirable properties, solutions based upon demand-side regulation have been much neglected in the literature, and rarely put into practice. Discussion of such systems provides a contribution towards the continuing debate regarding how best to improve fisheries management, to ensure that economic rents are neither purely dissipated, nor simply captured by a first generation of resource users
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
