Site factors determining epiphytic lichen distribution in a dieback-affected spruce-fir forest,on Whiteface Mountain, New York: microclimate
No full textRelationships between microclimatic site factors and cover of epiphytic lichen species were studied in a dieback-affected forest of Picea rubens and Abies balsamea on Whiteface Mountain, New York, U.S.A. Canonical correspondence analysis revealed an effect of light and water relations on epiphytic lichen abundance, but these factors only accounted for less than 10% of total variance in species data. Neither light nor evaporation, relative humidity, water-holding capacity of bark, or air temperature differed at the trunks between trees of different species or vitality. These results suggest that microclimate is probably not the main cause of significant differences in the epiphytic lichen diversity of spruce and fir and of living trees and snags. However, as canopy structure at the study site changed recently due to dense young growth of A. balsamea, it is possible that past differences in microclimate still exert an influence on present-day within-stand variation of epiphytic lichen abundance
The impact of powerful authorities and trustful tax payers: Evidence for the extended slippery slope framework from Austria, Finland and Hungary
Full text linkTax authorities utilize a wide range of instruments to motivate
honest taxpaying ranging from strict audits to fair procedures or
personalized support, differing from country to country. However,
little is known about how these different instruments and
taxpayers' trust influence the generation of interaction climates
between tax authorities and taxpayers, motivations to comply,
and particularly, tax compliance. The present research examines
the extended slippery slope framework (eSSF), which distinguishes
tax authorities' instruments into different qualities of power of
authority (coercive and legitimate) and trust in authorities (reasonbased
and implicit), to shed light on the effect of differences
between power and trust. We test eSSF assumptions with survey
data from taxpayers from three culturally different countries (N =
700) who also vary concerning their perceptions of power, trust,
interaction climates, and tax motivations. Results support
assumptions of the eSSF. Across all countries, the relation of
coercive power and tax compliance was mediated by implicit
trust, which leads to an antagonistic climate and enforced
motivation. The connection from legitimate power to tax
compliance is partially mediated by reason-based trust. The
relationship between implicit trust and tax compliance is
mediated by a confidence climate and committed cooperation.
Theoretical and practical implications are discussed
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
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
