Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Beyond "More is Better": Ecological Footprint Accounting for Tourism and Consumption in Val di Merse, Italy
No full textHabits of conservation, consumption and recycling are important determinants of economic throughput. Provincial governments interested in tourism's role in a diverse, steady-state economy may wish to orient tourism development around the tourist segments with less intensive consumption habits. We estimate consumption of energy and materials by tourists vacationing in Val di Merse, a rural region of Tuscany, Italy. We compare tourists and their host population by means of a consumption based indicator, the Ecological Footprint. Conclusions for planning and management are explored. While the average tourist is often thought to consume more on vacation than at home, and often more than local residents, our estimate of the tourist footprint as an equivalent resident (5.28 gha) is similar to that estimated for residents (5.47 gha), excluding arrival transport. In total, the tourist population (685 equivalent residents) in Val di Merse contributes an ecological footprint of 13,500 gha annually, compared to 74,500 gha due to local residents (pop. 13,624). Both levels are lower than the average 6.74 EF estimated for the tourist countries of origin. Arrival transport contributes an additional 32.8 gha per tourist equivalent resident, and accounts for 86% of the total tourism impact. Infrastructure, information provided, and traditional knowledge are discussed as possible ways Provincial governments can maintain or grow tourism flows while maintaining low ecological footprint, and while raising economic turnover relative to material and energy throughput. © 2006.

Adaptative environmental management of tourism in the Province of Siena, Italy using the ecological footprint
No full textAdaptive management as applied to tourism policy treats management policies as experiments that probe the responses of the system as human behavior changes. We present a conceptual systems model that incorporates the gap between observed and desired levels of the ecological footprint with respect to biocapacity. Addressing this gap (or 'overshoot') can inform strategies to increase or decrease visitation or its associated consumption in the coming years. The feedback mechanism in this conceptual model incorporates a gap between observed and desired ecological footprint levels of tourists and residents. The work is based on longer-term and ongoing study of tourism impacts and ecological footprint assessments from the SPIN-Eco Project. We present historical tourism and environmental data from the province of Siena, Italy and discuss the use of discrete, static environmental indicators as part of an iterative feedback process to manage tourism within biophysical limits. We discuss a necessary shift of emphasis from certain and static numbers to a process-based management model that can reflect slow changes to biophysical resources. As underscored by ecological footprint analysis, the energy and material use associated with tourism and local activity can erode natural capital foundations if that use exceeds the area's biological capacity to support it. The dynamic, and iterative process of using such indicators as management feedback allows us to view sustainability more accurately as a transition and journey, rather than a static destination to which management must arrive
Tourism and Climate Change: Two-Way Street, or Vicious/Virtuous Circle?
No full textThis paper presents the approach and reasoning behind two central conceptual diagrams relating tourism and climate change. The first diagram describes a typical polarisation in tourism and climate change knowledge management. It is argued that this polarisation restricts the collective body of knowledge and obscures important causal links between tourism and climate change phenomena. Developments are proposed in a second conceptual model which counters the tendency of scientists, policymakers, the tourism industry and NGOs to polarise along two research interests by discussing climate's influence on tourism vs. tourism's influence on climate; either of which could be interpreted as a primary limitation to the sustainability of tourism. The paper places into context key perspectives in the tourism-climate change discussions, addresses the difficulty of including system feedbacks between human activity and climate interactions, and draws attention to the underlying drivers of unsustainable trends. New strategic conceptual models are advocated to support long-term non-territorial collaboration, to incorporate adaptation and mitigation in ways which are not mutually exclusive, and to address the following paradox: that the cross-section of the global population driving the demand for tourism resources threatened by climate change are also disproportionately responsible for increased radiative forcing. © 2006 T.

Variations on the Author
No full text“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
No full textWe 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
No full textWe 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
