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
Use of Mobile Phone Technology to Support Improved Infant and Young Child Feeding Practices in Low- and Middle-income Countries: A Scoping Review
No full textSub-optimal Infant and Young Child Feeding (IYCF) practices persist in Low- and Middle-Income Countries (LMIC), contributing to the burden of malnutrition, morbidity and mortality. Contextualized behavior change communication (BCC) delivered through interpersonal support at the community level is effective for improving IYCF practices, but not widely available in LMIC. This scoping review examined the potential for mobile phone technology to facilitate greater access to quality BCC for IYCF. Four delivery channels were identified through a search of the published and grey literature and consultation with implementers. Direct messaging, voice counseling, job aid applications and interactive media each emphasize different BCC techniques. Four studies reported positive effects on IYCF practices with mobile phone-based BCC delivery, but contexts and designs vary. Further research is needed. The incorporation of mobile phone technology in BCC interventions should be guided by formative research to match both the content and delivery approach to the local context.M.Sc

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
Infant Feeding Practices in a Multi-ethnic Cohort of Vulnerable Women Registered in the Canada Prenatal Nutrition Program
Get PDFBackground: Breastfeeding rates are lower among socio-economically vulnerable women in Canada. Improved access to skilled lactation support is one priority action to address these disparities. The Canada Prenatal Nutrition Program (CPNP) aims to support breastfeeding among vulnerable women but little is known about participants’ infant feeding practices or effective models for delivering postnatal lactation support through the CPNP. Objectives: Data from a Toronto cohort of CPNP participants were examined to determine : 1) breastfeeding intensity levels at seven time points to six months postpartum, frequency of breastmilk supplement use by time point, and intervals of exclusive breastfeeding; 2) prevalence of expressed breastmilk use and associations between its use at two weeks postpartum and breastfeeding practices (any and exclusive) to six months; 3) prevalence of household food insecurity at six months postpartum and associations with continued and exclusive breastfeeding.
Methods: A pre/post study of a postnatal lactation support intervention was implemented at two CPNP sites but suspended prematurely due to the COVID-19 pandemic. Post-hoc analyses were conducted using the available dataset (study 1; n=151) and pooling it with data from a related study at another CPNP site providing free, in-home skilled lactation support (studies 2 and 3; n=337).
Results: At least 60% of study 1 participants provided breastmilk for >75% of daily milk feeds at all time points and 48% exclusively breastfed for at least three consecutive months, despite only 18% doing so for six months. In the pooled cohort, in-hospital formula supplementation was common (57%) and 34% used expressed breastmilk in the first two weeks postpartum. These early feeding practices were associated with breastfeeding cessation before six months and non-exclusive breastfeeding to both four and six months. Household food insecurity was highly prevalent (44%) in the pooled cohort but was not associated with breastfeeding practices.
Conclusions: Findings showed high rates of breastfeeding but a continued need for skilled lactation support from birth to improve exclusive breastfeeding. These findings inform adaptations to the redesign of the planned intervention study. Comprehensive assessment of infant feeding practices and household food insecurity in the national CPNP is also needed to shape future program delivery.Ph.D.2023-06-28 00:00:0
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
