Preface [Weather radar and hydrology]
No full textThe topic of “Weather Radar and Hydrology” brings together important science and technology challenges concerning the monitoring and forecasting of rainfall over space and time and how the pattern of rainfall is transformed by a varied landscape into surface water runoff and river flow across a city, region or country. It has significant practical application across a range of water resource functions, including flood forecasting and warning, flood design, urban drainage management, water supply and environmental services. The subject concerns developments in weather radar technology in combination with advances in hydrological application, and thus is of relevance to researchers in these fields, practitioners in the water industry and suppliers of weather radar systems.
These Proceedings bring together over 100 peer-reviewed papers presented at the International Symposium on “Weather Radar and Hydrology” (WRaH 2011), convened from 18 to 21 April 2011 at the University of Exeter, UK: see www.WRaH2011.org for details. The symposium was the 8th in a series that began in 1989 at the University of Salford (UK) under the title “Hydrological Applications of Weather Radar”. Subsequent symposia have been convened in Germany, Brazil, USA, Japan, Australia and France. WRaH 2011 marked a return to the UK after 20 years of successful symposia across the world. More than 250 people attended from a range of organisations – governments, academia, research bodies, national hydrometeoro¬logical services and consultancies – and travelled from countries spanning four continents. WRaH 2011 provided a forum for the exchange of experiences and ideas on the use of weather radar in hydrology with a particular emphasis on user applications for flood forecasting and water management. These Proceedings serve as a valuable record of this activity
Loneliness and Immune Gene Expression in Korean Adults: The Moderating Effect of Social Orientation
No full textObjective: Loneliness, the distress experienced from a perceived lack of desired interpersonal relationship, is detrimental to mental and physical well-being. One of the physiological correlates of chronic loneliness is alteration of immune transcriptional profiles, characterized by up-regulation of proinflammatory response and down-regulation of antiviral response, called conserved transcriptional response to adversity (CTRA) gene expression. Here, we examined whether the loneliness-CTRA link would be moderated by individual differences in social orientation-that is, the degree to which individuals are collectivistic versus individualistic. Method: In a sample of 152 Korean adults (aged 20 to 69, mean age = 44.64, 50% female), we examined the relationship between loneliness and blood cell CTRA gene expression as moderated by individual levels of collectivism (vs. individualism). Results: As predicted, social orientation significantly moderated the loneliness-CTRA link. Loneliness was associated with elevated CTRA expression among Koreans with high levels of collectivism (vs. individualism). In contrast, the loneliness-CTRA link was completely absent among those with lower levels of collectivism (vs. individualism). Conclusion: The current finding highlights the role that individual variation in social orientation plays in modulating the risk of loneliness on adverse health outcomes.
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
