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

Fixed Drug Eruption - An analysis.
Get PDFINTRODUCTION :
World Health Organisation has defined a drug as “a substance or
product that is used or intended to be used to modify or explore
physiological system or pathological state of the recipient”.
Adverse drug reaction is defined by WHO as “a response to a drug
that is noxious, unintended and undesired and occurs at doses used in
man for modification of physiological function”. ADRs affect upto 7% of
the general population and constitute upto 8% of hospital admissions.
Cutaneous ADRs are among the more commonly observed adverse
reactions to medications. Among the various morphological drug reaction
patterns encountered, Fixed Drug Reactions account for upto one third of
cases. According to many Indian studies, Fixed drug eruption is the most
common cutaneous adverse drug reaction pattern, constituting 25-40% of
cases. In the western world, it is next only to maculopapular rash as
the common cause of CADR. Several studies analysing the
epidemiological, pathophysiological, pharmacological and clinical
aspects of FDE are available in literature. Though clinically less severe,
FDE causes cosmetic embarrassment in many patients.
AIMS OF THE STUDY :
To find out the incidence, age and sex distribution of Fixed Drug
Eruption among patients attending the Department of
Dermatology, Government General Hospital, Chennai.
* To find out the proportion of FDE cases among various cutaneous
adverse drug reactions.
* To find out the common offending drugs and study the drug
specific clinical patterns and sites of involvement in the FDE cases.
* To study the different parameters of fixed drug reaction - Number
of episodes in a patient and mean length of time from drug
exposure to the development of FDE lesions during initial and
subsequent episodes.
* To confirm the drugs responsible for causation through patch
testing.
* To study the various histopathological characteristics of fixed drug
eruptions.
* To ascertain the role of CD8+ T-cells in causation through
Immunohistochemistry.
CONCLUSION :
1. The incidence of Fixed Drug Eruption among Dermatology OPD
attendees from Aug 2008 to Aug 2010 was found to be 0.54%.
2. The main age group affected was 21 – 30 years.
3. An almost equal sex incidence. was observed with the male to
female ratio being 1.23:1.
4. The incubation period observed during the first and subsequent
episodes was 13.4 days and 4.6hrs respectively.
5. The most common offenders were fluoroquinolones especially
ciprofloxacin seen in 14.5% of cases and levofloxacin in 10.5% of
cases. The next common offender was cotrimoxazole inducing
FDE in 11.8% of cases. Nonsteroidal antiinflammatory drugs were
the causative drugs in 19.73% of cases with diclofenac being the
main inducer followed by paracetamol.
6. Classical presentation was seen in 81.57% of cases. The other two
morphological patterns encountered were Bullous FDE(18.42%)
and Nonpigmenting FDE(1.33%).
7. Multifocal pattern was the most common pattern of distribution of
lesions. Solitary and generalised patterns were also encountered.
8. Extremities were the most frequently involved sites seen in 44.73%
of cases, followed in decreasing order of frequency by trunk, face,
oral mucosa, genital mucosa, lips and palms and soles.
9. There was no statistically significant difference between males and
females regarding the site of involvement . Clinically mucosal
lesions and lesions on the palms and soles were more commonly
encountered in males. Involvement of the lip was commonly seen
in females.
10. Though statistically insignificant, clinically significant associations
were observed regarding drug specific site of involvement.
Phenytoin induced FDE exclusively on the trunk. Paracetamol was
observed to induce bullous FDE preferentially on palms and soles
Ciprofloxacin induced lesions mainly on the extremities.
11. The rate of occurrence of associated local and systemic symptoms
was 78.95% and 14.47% respectively which is relatively high when
compared to previous studies.
74
12. Drug patch tests done to establish the causality of offending drugs
revealed positivity in 32.9% of patients. The testing was found to
be positive when done on lesional skin when compared to
nonlesional skin.
13. Histopathological examination of biopsy specimens produced
consististent findings in all the 33 cases in whom biopsy was
performed.
14. Immunohistochemical analysis done using antibodies to CD8
revealed positivity in both acute and chronic cases, establishing the
role of these cells in causation of FDE.
In the current study, the number of patients observed was less
when compared to the previous studies. So statistical analysis did not
reveal any significance regarding the sex specific and drug specific site
of involvement
Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
