No full textThis is a replication dataset for the manuscript titled: "Surveillance of respiratory viruses at health facilities from across Kenya, 2014."
These data originated from surveillance carried out in 11 sites across Kenya. It contains patients' demographics and clinical features, samples tested, samples positive, respiratory virus targets, years and months of sample collection.</p
Drivers of respiratory syncytial virus seasonal epidemics in children under 5 years in Kilifi, coastal Kenya
No full textRespiratory syncytial virus (RSV) causes significant childhood morbidity and mortality in the developing world. The determinants of RSV seasonality are of importance in designing interventions. They are poorly understood in tropical and subtropical regions in low-and middle-income countries. Our study utilized long-term surveillance data on cases of RSV associated with severe or very severe pneumonia in children aged 1 day to 59 months admitted to the Kilifi County Hospital. A generalized additive model was used to investigate the association between RSV admissions and meteorological variables (maximum temperature, rainfall , absolute humidity); weekly number of births within the catchment population; and school term dates. Furthermore, a time-series-susceptible-infected-recovered (TSIR) model was used to reconstruct an empirical transmission rate which was used as a dependent variable in linear regression and generalized additive models with meteorological variables and school term dates. Maximum temperature, absolute humidity, and weekly number of births were significantly associated with RSV activity in the generalized additive model. Results from the TSIR model indicated that maximum temperature and absolute humidity were significant factors. Rainfall and school term did not yield significant relationships. Our study indicates that meteorological parameters and weekly number of births potentially play a role in the RSV seasonality in this region. More research is required to explore the underlying mechanisms underpinning the observed relationships
Replication Data for: Near complete genomes of eight human astroviruses recovered from diarrheal stool samples of hospitalized children in coastal Kenya in 2019
No full textThis is a replication dataset for the publication: "Near complete genomes of eight human astroviruses recovered from diarrheal stool samples of hospitalized children in coastal Kenya in 2019.
The dataset is part of long-term surveillance of enteric viruses associated with diarrhea among children under 13 years admitted to the KCH study. This dataset contains results of samples positive for human astrovirus by real-time PCR for the period 13th April 2019-23th July 2019. Aside from the samples tested and results of the tests, it also contains the patients’ sociodemographic characteristic, cycle threshold and symptoms (diarrhoea and Vomiting).The dataset is used to generate new HAstVs genome sequences from RT-PCR positive samples collected from children hospitalized with diarrhea in Kilifi Kenya.
The raw sequence data were deposited in the Sequence Read Archive (SRA) under BioProject accession number PRJNA692787 and BioSample accession numbers SAMN17370496 to SAMN17370503. The genome sequences generated here were deposited in GenBank under accession numbers MW485038 to MW485045. </p
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
Replication Data for: The cost of care for children hospitalized with respiratory syncytial virus (RSV) associated lower respiratory tract infection (LRTI) in Kenya
No full textThis is a replication dataset for the submitted manuscript titled: "The cost of care for children hospitalized with respiratory syncytial virus (RSV) associated lower respiratory tract infection (LRTI) in Kenya."
These data contain RSV costing information on children under five years of age admitted at Kilifi County Hospital and Siaya County Referral Hospital with symptoms of acute lower respiratory tract illness or severe acute respiratory infection (SARI). It has information on the direct and indirect costs of taking care of a child hospitalized with RSV-associated illness. </p
Replication Data for: Prevalence and predictors of adverse birth outcomes and implications for uptake of new maternal vaccines in Kenya
No full textA cross-sectional survey was conducted to collect data on birth outcomes from women residents of the health and demographic surveillance systems (HDSS) areas of Siaya and Kilifi, Kenya; and from the maternity wards of Siaya County referral hospital and Bondo sub-county hospital. Participants of the HDSS sites had pregnancies registered in the years 2017 to 2020 through census rounds and were traced at home for interview. All women had a birth outcome by the time of data collection
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
