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
Main characteristics of type 1 and type 2 diabetes patients interested in the use of a telemonitoring platform
No full textDiabetes is one of the most challenging health problems of the 21st century. Using a telemonitoring platform could be beneficiary for persons with this condition. Such a platform could enhance the electronic communication between different actors in a private and secure way. Patients could receive timely (personalised) feedback; less transcription errors could occur and a higher reliability of direct transfer of blood glucose data into the system could be the result. Until now, it has however never been investigated whether those persons are actually interested in using such a platform.
The aim of this study was therefore to investigate whether diabetes patients are interested in using a telemonitoring platform and if so, whether characteristics of interested users could be distinguished.
Because no questionnaire existed to assess this interest, a Telemonitoring Health Effect and Readiness Questionnaire (THERQ) was developed and validated (Chapter 3). The preliminary findings suggest it is a valid, reliable, brief and easy to administer scale. In 2008, quite some patients were interested in the use of some services offered via a telemonitoring platform. In 2011, there was even a growing interest. Currently, patients recruited via a Community Health Centre (study 2011) do not use any electronic form (e.g. email) to communicate with their healthcare professional. However, also in this group of patients, about 40 percent of the patients was interested in using it. While the interest in 2008 especially was for using such a platform for communication from the home environment with their healthcare professional, in 2011 there was quite some interest in using such a platform during holidays. Even though these results cannot be compared with other studies, they seem promising.
Another important question in this study was to look for characteristics of interested users of a telemonitoring platform. Because some telemonitoring studies already showed a link with empowerment, one of the aims of this study was to look for a link between empowerment and interest in the use of a telemonitoring platform. No Dutch version of the Diabetes Empowerment Scale (DES) existed, so the DES was translated into Dutch and the psychometric properties determined (Dutch-DES-20) (Chapter 4). The preliminary results suggest the Dutch-DES-20 is a valid and reliable instrument.
To determine criterion validity, it was hypothesised that patients with high empowerment scores would have better metabolic control, thus lower HbA1c-levels. This study showed that patients with an insulin treatment and a better metabolic control were indeed more empowered. Also, patients being able to cope well and with good motivation (subscale 2) were more empowered, irrespective of the group. It was further hypothesised that patients with high empowerment scores also would have high scores on the Dutch-DES sub-questions. Indeed, patients on multiple daily insulin injections with high empowerment scores have a high self-rated understanding of diabetes and its treatment, feel themselves able to fit diabetes into their life in a positive manner and feel themselves capable to ask questions to their diabetes professional. Even though it was expected that diabetes would not prevent empowered diabetes patients from doing their normal daily activity, no significant correlations could be found. The interviews learned it was a quite difficult question to answer. Patients mentioned that it was not obvious to reflect on a life without diabetes while having it already for quite some time. In our sample, more than two thirds was already diagnosed for more than ten years.
In Chapter 5, characteristics of interested users were described. The study in 2008 was performed in a hospital setting, while in the study performed in 2011, patients were recruited via a Community Health Centre (primary care setting), via the Flemish Diabetes Centre and via an online questionnaire. The most important results were found for patients with only insulin treatment and those with a combined treatment; interesting groups also from a clinical point of view. For those patients it was found, as expected, that younger patients, patients using a computer or searching on the Internet (making use of a forum or searching for diabetes-related information), and those already keeping data on computer are more interested in using a telemonitoring platform. In 2011, the use of a smartphone and the use of social media seemed to be very important characteristics as well.
It was further found that patients with only an insulin treatment without adequate metabolic control seem to be more prone to use the telemonitoring platform. From a clinical point of view, having an adequate metabolic control is important, i.e. to diminish the risk to develop chronic complications. The present results suggest a link between eagerness to use a platform and those in need for a better control. For patients with a combined treatment regimen, a link was found with empowerment; i.e. those with lower empowerment scores seem to be more prone to use a telemonitoring platform. Even though further research is required, it could be hypothesised that this group of patients is entering a new stage in their disease and thus need to adapt their lifestyle to this new situation.
CONCLUSION : The preliminary results of this study show that the Dutch Diabetes Empowerment Scale (Dutch-DES-20) as well as the Telemonitoring Health Effect and Readiness Questionnaire (THERQ) are valid and reliable instruments. The results further show that there is substantial growing interest in using a telemonitoring platform. For type 1 and type 2 diabetes patients with only insulin treatment it could be used to improve their metabolic control; for type 2 diabetes patients with a combined treatment regimen to improve empowerment. The selection of patients could be based on present Internet use, use of social media and on the fact they already log diabetes data
Dietary habits in preschool children: as a basis for the development of a methodological framework for future dietary surveillance
No full textkoamabayili/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
