Synthesis and derivatisation of a novel spiro [1-benzofuran-2,4'-piperidin] -3-one scaffold
No full textThe synthesis of a novel spiro[1-benzofuran-2,4'-piperidin]-3-one scaffold 6 has been achieved in five steps with an overall yield of 47%. The versatility of the spiropiperidine scaffold in the context of library synthesis is exemplified by selective and sequential derivatisation of the amino and aryl bromide functional groups, including the development of multi-step telescope reaction matrices
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
Death, disintegration of the body and subjectivity in the contemporary horror film
Get PDFThis thesis is an attempt to account for the contemporary American
horror film's increased reliance upon images of bodily dismemberment
and decay. At the core of this exploration is an inspection of the
body's capability as a metaphor by which our understanding of the
relation of self to society is articulated. The horror film is shown
to be a genre traditionally disposed towards the interrogation of
categories of human identity,and one which is now responding to the
kind of cultural developments often referred to by the expression
postmodernism. As such the genre is placed in a context of other
social discourses about the body, death, disease and decay.In proposing the body as the central metaphor of the modern horror film,
and pursuing its significance in a range of recent film texts, the
thesis triesto provide a positive basis for understanding an aspect
of popular culture often left 'explained' by accusations of exploitation
or dismissed by the traditionalists as aberrant.
The thesis does not attempt to be a theory of genre per se, nor does
it offer an exhaustive account of the field; the outlining of the emergence
of a new tendency is not meant to imply that more conventional material
has been discontinued. 'Body Horror' is argued to be the most important
development in the field however, and the work concludes after demonstrating
its vitality in recent examples where its deployment takes radically varied
positions with respect to the construction of the masculine subject in
particular.
The work is broken down into five Chapters. In Chapter One the existing
theoretical literature is critically examined. In Chapter Two, the nature of
the contemporary horror film is laid out. In Chapter Three the body as a symbo
is considered in relation to the genre. In Chapter Four this idea is developed
through textual analysis in relation to discourses of death and disease. In
Chapet Five the emergence of a postmodern horror film is considered. A conclusion acts as a summary and as a focus in which the implication of the
work for feminist and psychoanalytical theories of the subject can be drawn
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
