No full textKnowledge transfer between stakeholders in the field of urban forestry and green infrastructure: Results of a European survey
No full textThe establishment and management of green infrastructure in cities require the involvement of a complex network of stakeholder groups, who may differ sharply from one another in their expectations and approaches. Bridging the communication gaps between them is essential for creating and maintaining urban green spaces and expressing their full potential and multi-functionality. In this research, we investigate the ways that knowledge is transferred from one stakeholder group to another, and we identify the relative strengths and weaknesses of the different modes by which these actors collaborate and interact in practice. Data obtained from this first-ever exploratory survey of public administrators, practitioners and academic researchers involved with urban green infrastructure in Italy and other European - but also some extra-European - countries indicate that there are positive attitudes toward forms of collaboration, mainly because of the need to achieve common aims such as encouraging innovation, identifying practical problem solutions and accessing sources of funding. Our analysis suggests that stakeholders need to better understand the importance of forming cohesive teams, of optimizing financial resources, and of finding a common language to bridge their diverse disciplinary backgrounds. To be effective, future models of knowledge transfer will have to consider the current needs of end users without neglecting the long-term potential of emerging communication technologies such as e-learning, and vocational training must not only be based on high-quality content, it must also include practical activities and facilitate personal contact that can lead to enhanced collaboration
Speaking "Green": A worldwide survey on collaboration among stakeholders in Urban park design and management
Get PDFUrban parks can provide a range of valuable benefits, including essential ecosystem services. Their successful management is often in the hands of government agencies, who rely on interaction with other stakeholders for specialized knowledge. In order to examine the attitudes of different actors toward professional collaboration and to identify ways of improving the effectiveness of knowledge transfer, a global survey was conducted among the members of theWorld Urban Parks (WUP) association. The results show that representatives of public agencies, due to their lower level of up-to-date knowledge, have a pressing need for collaboration with private practitioners, academic researchers, and community advocates. Interactive, face-to-face learning is most valued, especially if it includes practical as well as theoretical information. Most respondents indicated that 'personal contacts' are more important than professional affiliation for the initiation of new collaborations, and for many, the possibilities for joint creativity are the most highly prioritized benefits. Obstacles to be addressed include 'bureaucracy' and a 'divergence of interests or approaches among stakeholders', indicating the need for a "common language"-i.e., "speaking green"-which may accommodate diverse priorities and concerns. In accomplishing this, a special role is seen for international professional associations that can help to build bridges between countries and professions
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
