No full textThe value of neighborhood greenspace for children
No full textAcross the globe, urbanization is increasing, intensifying the pressure on greenspaces, which affects all its users, including children. This is potentially concerning since exposure to nature enhances children's health and well-being. With regard to well-being, while robust evidence is present on the positive relationship between exposure to nature and well-being of children, currently no monetary valuation of the well-being benefits exists, making them more difficult to appropriately include in public decision-making regarding greenspace development. This study, for the first time, puts a monetary value on neighborhood greenspace exposure for children using the life satisfaction approach (LSA). This approach has been employed for the monetary valuation of environmental goods and issues but has not been extended yet to value the well-being of children. The LSA quantifies the influence of neighborhood greenspace on children's life satisfaction (LS) and compares it to the impact of other determinants of their LS that can be valued in monetary terms. In that way, the LSA calculates the amount of money to offset a change in neighborhood greenspace to keep the child at the same level of LS. As a result, the LSA does not require children or their parents to assign monetary values themselves. Data were gathered from 430 parent-child pairs in 29 different primary schools in Flanders (age range of children 10-12). The monetary value will be determined based on the tradeoff between the impact of the exposure of neighborhood greenspace on children’s LS and the impact of working hours of parents and time children spend with their parents on children’s LS. This time will be valued using the market replacement cost and opportunity cost method. The results of the study reveal the monetary value of neighborhood greenspace in terms of improvements in children's self-reported LS

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
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
