Notas sobre la flora acuática de Ciudad Real
No full textMEDINA, L., GARCÍA RÍO, R. & DRAPER, D. 2002. Notas sobre la flora acuática de Ciudad Real. Bot. Complutensis 26: 53-58. Se comentan 4 plantas hidrófilas, especies raras o amenazadas en Castilla-La Mancha, recolectadas en la provincia de Ciudad Real. Se cita por segunda vez Marsilea batardae en la provincia y se amplía el área de distibución de Butomus umbellatus, Hydrocotyle vulgaris y Marsilea strigosa. MEDINA, L., GARCÍA RÍO, R. & DRAPER, D. 2002. Notes on Ciudad Real aquatic flora. Bot. Complutensis 26: 53-58. Four aquatic plants, all of them rare or threathened species in Castilla-La Mancha, have been collected in Ciudad Real province. Marsilea batardae is recorded for the second time for the province and the distribution area of Butomus umbellatus, Hydrocotyle vulgaris and Marsilea strigosa is extended
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
A comparison of canid depredation research published in journal and gray literature
Get PDFWe evaluated whether coyote and wolf depredation management research in peer-reviewed journals differed from research in gray literature (e.g., conference proceedings, research reports). Regression analysis showed that journal published research was more likely to have used statistical analyses and have authors with academic affiliations. These results show that reliance on one literature type may lead to management and research decisions based on partial information. Focusing on journal literature may reduce the likelihood of encountering descriptive (i.e., non-statistical) analyses that could inform management and illuminate future avenues of research. For instance, half of the 76 descriptive experimental research findings we located, including 10 controlled experiments, were found only in gray literature documents. Our results highlight that canid depredation managers and researchers should utilize both journal and gray literature
Incorporating geographic context into coyote and wolf livestock depredation research
Get PDFApplying research results to new locations and situations can be confounded by differences in the geographic context between the original and the applied study sites. Replication studies and meta-analyses may be similarly hindered. We investigated how often canid management research reports (e.g., journal articles, conference proceedings) included information on historical/current lethal control, alternative prey availability, landscape features, and seasonal and settlement characteristics. We included experimental research published between 1970 and 2018, focusing on livestock depredations by wolves and coyotes in North America. Reporting on contextual factors was highly variable; seasonal context was included in 83% of research findings; human settlement characteristics were reported in only 8%. Contextual information was more common in journal versus grey literature, and in reports with academic versus government-affiliated primary authors. Discussions of the effects of contextual factors on livestock depredation mitigation strategies were underdeveloped. Yet, geographic context of research is vital; it can alter animal behaviour and reduce the efficacy of applied mitigation. We suggest reporting guidelines to improve comparisons and meta-analysis opportunities, which may enhance comparisons and management decision making
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
