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
Vulnerability and Transformation of Indonesian Peatlands
Full text linkThis open access book deals with restoring degraded peatlands to help mitigate global warming, to which SDG 15 and SDG 13 are directly related. The book analyzes peatland degradation and restoration of the Indonesian peatland ecosystem through the integrated lens of resilience, vulnerability, adaptation, and transformation. It sheds light on what constitutes "resilience" of the peat swamp forest, digs deeper into local knowledge in developing the studies on institutions, governance, and ecological conditions that support the resilience of the peat swamp forest to elaborate on the idea of transformation in today's degraded peatlands. While peat swamp forests may be resilient, they remain highly vulnerable. The book analyzes restoration efforts through rewetting, revegetation, and rehabilitation of the local livelihoods with the concepts of adaptation and transformation. The integrated analysis covers fieldwork of more than a decade and various aspects such as agrarian and social changes, biological changes (birds, mammals, and termites), carbon emission, water control, timber use, revegetation efforts, and the Indonesia Sustainable Palm Oil (ISPO) program implementation. It also employs the ideas of vulnerability, resilience, adaptability, and transformation based on expanded studies on peatlands and observations of and participation in multiple efforts to prevent fires and restore the degraded peatland by researchers, the government, non-government organizations (NGOs), private companies, and last but not least, the local people. The discussion includes the period of pre-degradation and several efforts at peatland restoration for a better understanding and analysis of the long-term peatland dynamics
Characteristics of Bird Community Response to Land Use Change in Tropical Peatland in Riau, Indonesia
No full textTropical peatlands have increasingly been targeted for logging or conversion to plantations in recent years. Tropical peatlands are unique ecosystems rich in biodiversity, but they have not attracted as much researcher attention as tropical forests, for example. There is still limited understanding of the ecological significance of peatland disturbance, or of the ecological resilience of peatland ecosystems. This study focuses on birds as indicator species in peatland ecologies. It compares bird communities in peatlands and non-peat lowlands in terms of: (1) species richness; (2) feeding guilds; and (3) responses to disturbance. Our research team analyzed bird communities in peatlands under several different land uses in Riau in comparison to those living in non-peat lowlands in Sumatra Island. We found that species richness in natural forests was lower in peatlands than in non-peat lowlands. The Jackknife estimator of species richness was 77.2 in natural forests on peatland, whereas on non-peat lowland, it was 114.8 and 241. Compared to non-peat lowland forests, the number of terrestrial insectivore and woodpeckers was lower in peatlands. Non-metric multidimensional scaling (NMDS) analysis showed that the bird community composition in peatland forests is unique compared to non-peat lowland forests, as they showed completely different lines of avifauna. Nevertheless, avifauna in disturbed sites on peatland were close to avifauna in disturbed non-peat lowland sites, which indicates that the disturbance of peatland would lead to homogenization of avifauna and loss of uniqueness, which in turn, leads to loss of biodiversity. Bird community composition in peatlands was very sensitive to land use change. Shifts in the community composition along the disturbance, as measured by Euclidean distances in the NMDS plot between each disturbed habitat and natural forest, were greater in peatland than in non-peat lowland. Although our knowledge and data of peatland ecologies are limited, it seems likely that certain peatland avifauna can only survive in natural peat swamp forest

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
