Effects of silver sulfadiazine and actilite honey on bacterial wound colonisation and wound healing in children under twelve years with partial superficial burn wounds at University Adult Teaching Hospital in Lusaka, Zambia
Get PDFThesisBurn wounds are a global public health concern and Zambia has not been spared. Burn wounds account for 6% of surgical admissions yearly and yet are amongst the common causes of mortality at University Teaching Hospitals (UTH). Burn wounds seen at UTH affect children more than adults and the common size is ≤ 20 per cent and partial superficial thickness in depth. The hospital has no burns unit and as such patients are admitted in general wards where cross infection is not uncommon. With high infection and mortality rates at UTH this study is of importance as it examined the effects of honey and SSD on bacterial wound colonisation and wound healing in paediatric partial superficial burn wounds of ≤ 20 per cent TBSA. This two-arm open label randomised trial was done at UTH over a period of seven months (July 2017-January, 2018). Children under twelve years with ≤ 20% partial superficial burn wounds were recruited. They were then randomly allocated to either honey or SSD group. Demographics were noted on recruitment. Swabs for microbiological evaluation were collected on day 0, 3, 7 and 10 and wounds were assessed for healing. The University of Zambia Biomedical Research and Ethics Committee approved the research. Of the 64 patients, 32 were allocated to each group and showed 1:1 ratio in both groups. The modal age distribution was 1-2 years and the percentage burn wound surface area was 6-10 percent in both age groups. At baseline there was no significant difference in bacterial wound colonisation (80% in honey group and 83% in SSD group; p = 0.74). However, by day 10 on treatment, there was significant reduction in bacterial wound colonisation (Honey Vs SSD; P = 0.026). Wounds treated with Actilite® honey healed quicker than those treated with SSD (Mean 11± 4, 15±6, P=0.0049).The study showed that treatment of children under 12years with partial superficial burn wounds of ≤ 20 per cent TBSA using Actilite® honey significantly reduced levels of bacterial wound colonisation by day 10. It was further demonstrated that wounds treated with Actilite® honey healed at a faster rate compared to those treated with SSD.

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
