A study to determine the forensic quality of records and record keeping by dentists in the greater Cape Town area
Full text linkMagister Chirurgiae Dentium - MChD (Maxillo-Facial & Oral Surgery)South African dentists have a legal and ethical obligation to maintain complete and
comprehensive dental records. In addition to the legal and ethical requirements, dental records
are also important in the case of medico-legal issues, quality assurance processes and forensic
purposes. Valuable forensic evidence contained in dental records are used in the identification
of victims of mass disasters, personal victim identification e.g. in severely decomposed or
skeletonized remains where DNA or other biometric data are not available. The victim
identification process is highly dependent on complete, legible and accurate dental records. A
review of the literature however shows that dental record keeping practices are sub-optimal
worldwide.
There is a paucity of studies in South Africa regards to dental record keeping practices. The
aim of this study was to assess the record keeping practices of a sample of private practicing
dentists in Cape Town and surrounding towns, for forensic dental purposes. Knowledge and
awareness regards to forensic odontology as well as adherence to the guidelines prescribed by
the Health Professional Council of South Africa were also assessed. This was a cross-sectional
descriptive study, employing a researcher-administered questionnaire and a dental checklist for
forensic valuable items in the dental file. The results were entered in a MS Excel spreadsheet
and statistically analysed using IMB SPSS Statistics.
This study concluded that most of the dental records kept by Cape Town dentists are near to
optimal and would be helpful during forensic odontology investigations. However,
shortcomings in record keeping practices exists which may compromise the forensic accuracy
of their dental records. The study also shows a significant difference in dental record keeping
practices by dentists practicing in lower income areas in Cape Town, compared to those
practicing in economic affluent areas. The dentists in this study adhered to most of the
guidelines prescribed by the Health Professional Council of South Africa however, important
medico-legal information was missing from most dental records. This study hopes to contribute
to future comprehensive studies in the broader South Africa to determine the validity of dental
records for forensic odontology purposes
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
