The interaction between surface waves and tidal currents
No full textThe interaction between wind-generated gravity waves and tidal currents is examined from the starting point of the gravity wave energy budget equation of Longuet-Higgins and Stewart, Equations are, developed whichIallow the variation in the short wave amplitude and wavenumber to be predicted for a linear tidal wave system having a standing wave and a progressive wave component. An additional term, unmentioned by Longuet-Higgins and Stewart, is shown to have an important role in describing the physical mechanism of the interaction and in the magnitude of the variation produced Wave data. from the North Sea is shown to exhibit this variation with the correct phase but with an amplitude variation 40% greater than predicted.A numerical model is set up to allow predictions to be computed for conditions where an analytical solution to the energy budget equation is not possible, e.g., for waves and tides in variable depths, 'Wave data from Southampton Water, under short fetch conditions, show an upward trend in wave energy when the tidal current begins to ebb and the numerical solutions are used to. show this is consistent with the wave-current',interaction. n The high variability' in wave energy between consecutive wave records in Southampton Water cannot be accounted for by this interaction theory and it is necessary to postulate the importance of other mechanisms in causing this variability.</p
Exploring the impact of a diagnosis of Huntington’s Disease on couple relationships
No full textThis study explores the impact of a diagnosis of Huntingtons Disease (HD) on couple relationships. A qualitative research method was used, based on the Free Association, Narrative and Interview Method, in order to interview three couples and four individuals. The couple relationships examined were at different stages of the HD illness trajectory, ranging from one couple where a diagnosis was made eighteen months before interview to two couples whose partners had died following several years of illness. From a thematic analysis of interview content, three over-arching themes and ten sub-themes were identified. The first over-arching theme refers to the ways that couples first became fully aware of the family history of HD and the implications this knowledge had for their lives and others within their families. The second overarching theme tracks the different ways that this knowledge was handled by the couple themselves and with other family members. The third overarching theme identifies key dilemmas faced by couples in managing the transition from a pre-illness to an illness dominated relationship. These dilemmas were-a) balancing anxious concern with a respect for independence, b) managing the loss of a sexual relationship and c) managing the move into residential care. All three of these challenges can be understood as being linked to how couples regulate emotional and physical distance during the course of the illness trajectory
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
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
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
