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
Integrated community case management of malaria and pneumonia in eastern Uganda : care-seeking, adherence, and community health worker performance
No full textBackground: Despite being easily preventable and treatable, malaria and pneumonia are major killers of children aged less than five years. Integrated community based interventions through which lay persons called community health workers (CHWs) can manage malaria, pneumonia, diarrhea and neonatal conditions are recommended by WHO and UNICEF. However, there is limited information on care-seeking and performance of CHWs in the context of integrated illness management.Main aim: To assess care-seeking and quality of care in integrated community case management of malaria and pneumonia in children aged less than five years in Uganda so as to inform the implementation of integrated community case management of childhood illness strategy (ICCM). Methods: Four studies (I-IV) were nested in a cluster randomized trial in Iganga-Mayuge demographic surveillance site in eastern Uganda. In this trial CHWs treated malaria and pneumonia (intervention arm) or malaria alone (control arm) in children aged 4-59 months. Performance of CHWs (I) was assessed using: questionnaires (with knowledge tests, case scenarios) and record reviews for 125 CHWs; observations among 57 CHWs in the intervention arm; and four focus group discussions with CHWs. Adherence to treatment was assessed using pill counts and caregiver reports among 1256 children treated by CHWs (II). Receipt of prompt and appropriate antibiotics for pneumonia symptoms and treatment outcomes were assessed among 1276 children treated by CHWs (III). Care-seeking and management of malaria and pneumonia were assessed among 1095 children and from 13 key informant interviews (IV).Results: Care-seeking from CHWs was higher in the intervention than the control arm (31% vs 22%, p=0.01) (IV). CHWs’ performance on malaria symptoms was similar in the intervention and control arms on: overall knowledge, eliciting signs and symptoms, and prescribing (I). More children treated by CHWs received prompt and appropriate malaria treatment compared to other health providers (37% vs 9%, pConclusions: CHWs’ performance on malaria was not affected by additional roles of pneumonia management, but they had challenges in assessment of pneumonia symptoms. CHWs should be supported with continued training, adequate supervision and provision of drugs, diagnostics and other supplies.List of scientific papersI. Joan N.

Facilitators and barriers to Tuberculosis case notification among private health facilities in Kampala Capital City, Uganda.
No full textIntroductionPrivate Health Facilities (PHFs), Uganda's main healthcare providers, are indispensable stakeholders in the national tuberculosis (TB) program's efforts to improve TB case notification and combat the epidemic. However, notification rates remain relatively low in PHFs compared to public providers. In this study, we sought to assess facilitators and barriers to TB case notification among private facilities in Kampala Capital City.MethodsWe conducted a cross-sectional study utilizing a mixed-methods approach to assess facilitators and barriers to TB notification in Kampala Capital City between March and July 2022. For the quantitative strand of the study, we interviewed the TB focal persons at 224 PHFs using a structured questionnaire and for the qualitative, we conducted 14 key informant and in-depth interviews with Ministry of Health-Uganda staff, and TB focal persons at the Kampala Division administration level and at the PHFs. The quantitative analysis involved Modified Poisson regression and the qualitative analysis was carried out using thematic analysis to identify the facilitators and barriers to TB case notification.ResultsOf the 224 PHFs surveyed, the majority, 39.3%(88), were facilities in Nakawa division and 55.4% (124) of the respondents were male, with a mean age of 32.6 years (SD = 8.6). We found that the prevalence of TB case notification was significantly lower for facilities in Kawempe (PR 0.16; 95%CI 0.05,0.47) and Nakawa (PR 0.39, 95%CI 0.21,0.73). Notification was lower among facilities that had no guide for TB screening and diagnosis (PR 0.50; 95%CI 0.25,0.97) and among those facilities where training of other health workers at the facility in TB diagnosis was unknown (PR 0.35; 95%CI 0.13,0.93). Qualitative data showed that the main facilitators of TB case notification were: regular engagements between the NTLP and private health providers and, provision of materials and support to conduct case finding, while the main barriers included TB stigma, lack of resources such as TB diagnostic facilities.ConclusionsPHFs in Kampala Capital City are receptive to programmatic TB case notification. However, they need regular supervision and engagement activities to ensure that they have updated knowledge, equipment and funding support to carry out TB case notification according to policy
Pathways to diabetic care at hospitals in rural Eastern Uganda: a cross sectional study
No full textAbstract Background Prompt access to appropriate treatment reduces early onset of complications to chronic illnesses. Our objective was to document the health providers that patients with diabetes in rural areas seek treatment from before reaching hospitals. Methods Patients attending diabetic clinics in two hospitals of Iganga and Bugiri in rural Eastern Uganda were asked the health providers they went to for treatment before they started attending the diabetic clinics at these hospitals. An exploratory sequential data analysis was used to evaluate the sequential pattern of the types of providers whom patients went to and how they transitioned from one type of provider to another. Results Out of 496 patients assessed, 248 (50.0%) went first to hospitals, 104 (21.0%) to private clinics, 73 (14.7%) to health centres, 44 (8.9%) to drug shops and 27 (5.4%) to other types of providers like community health workers, neighbours and traditional healers. However, a total of 295 (59.5%) went to a second provider, 99 (20.0%) to a third, 32 (6.5%) to a fourth and 15 (3.0%) to a fifth before being enrolled in the hospitals’ diabetic clinics. Although community health workers, drug shops and household neighbours were utilized by 65 (13.1%) patients for treatment first, nobody went to these as a second provider. Instead patients went to hospitals, private clinics and health centres with very few patients going to herbalists. There is no clear pathway from one type of provider to another. Conclusions Patients consult many types of providers before appropriate medical care is received. Communities need to be sensitized on seeking care early from hospitals. Health centres and private clinics need to be equipped to manage diabetes or at least diagnose it and refer patients to hospitals early enough since some patients go to these health centres first for treatment
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
