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
Health Literacy of Mothers Regarding Associated Factors of Pre-Ruptured Membranes on Perinatal Outcomes at Thulamela B Clinics
Full text linkMCurDepartment of Advanced Nursing SciencesPre-rupture of membranes prior labour initiation could complicate approximately 5% of pregnancies and could be associated with a high incidence of perinatal morbidity and mortality complications. The major complication could be cord compression resulting in hypoxia. The aim of this study was to assess the health literacy of lactating mothers regarding associated factors of pre-rupture of membranes on perinatal outcomes at Thulamela B clinics of Vhembe district. A quantitative research approach with a cross-sectional descriptive design was used.
The study population comprised a total of 210 lactating mothers within 6 weeks post-delivery.
Data were collected by the researcher through self-administered questionnaires. The IBM Statistical Package for Social Sciences (SPSS) version 25 was used for data analysis. The results are presented in the form of tables and graphs based on probability allowing judgement to be made on variables. Validity and reliability was ensured. Ethical clearance was obtained from the University of Venda Research Ethics Committee and permission to access health facilities from Limpopo Province Department of Health.
Data revealed that maternal health literacy was very limited, implicated by low literacy level, culture, cluster family decision regarding health care, reliance on lay persons for health information and limited health information from health care professionals as evidenced by late booking, failure to recognize the significance of pre-ruptured membranes and delay in seeking health. Recommendations included emphasis on active participation and health information topic suggestions by obstetric clients; midwives to provide woman-centred care with health education being a norm; systems in organization to consider maternal health literacy extension to families and the community and also recommendations to policymakers to utilize media campaigns for promoting maternal health literacy.NR
A Model to Enhance the Continuity of Postnatal Care by Primary Caregivers in Selected Districts of Limpopo Province
Full text linkPhD (Heath Sciences)Department of Advanced Nursing SciencesPostnatal women are discharged within six hours after delivery and it is documented that about three quarters of neonatal and maternal deaths occur during the first week of life, of which about half of the deaths occur in the home environment during the immediate postnatal care period. The continuity of postnatal care by primary caregivers need to be explored. This study sought to develop a model to enhance the continuity of postnatal care by primary caregivers in the selected districts of Limpopo Province of South Africa.
The convergent parallel mixed method was used where explorative, descriptive and contextual qualitative approaches were run concurrently with the descriptive quantitative approach. For the qualitative approach, non-probability purposive sampling was used to select 18 primary caregivers from the selected districts of Limpopo Province. Qualitative data were collected through in-depth one-to-one interviews and analysed through Tesch’s open-coding method. Trustworthiness was ensured through credibility, confirmability, dependability and transferability. For the quantitative approach, non-probability sampling was used to sample 100 midwives at designated health facilities of the selected districts. Data were collected through the Likert scale questionnaire and analysed through the Statistical Package for the Social Sciences (SPSS) version 25.0. Reliability and validity of the instrument was ensured through systematic literature review and a pilot study.
Both quantitative and qualitative data analysis yielded three main themes as follows: facilitators to continuity of postnatal care by primary caregivers; barriers to continuity of postnatal care and perceptions of primary caregivers regarding the interactions with midwives on the continuity of postnatal care. In the discussion of findings, qualitative findings were supported by quantitative findings. Based on the findings of phases 1 and 2, Walker & Avant’s method was followed to conduct concept analysis of the core concept. Concept analyses formed bases for the development of a model for continuity of postnatal care by primary caregivers. The model was validated with 19 participants consisting of managers and
midwives from the Vhembe District health care facilities. The group validated the actionable plans using a closed-ended checklist to verify whether the action plans were congruent with practice.
The results were analysed through simple descriptive statistics where the data were summarised using frequency distributions. The results indicated that the actionable plans could be applicable to practice and may need slight modification to suite the institutional needs prior operationalization. Recommendations were made on Maternal and Child Health Directorate, midwives and primary caregivers. Topics for further research were also suggested.NR
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
Factors associated with anaemia in pregnancy: a case study of Matibidi Village, Ehlanzeni District, Mpumalanga, South Africa
No full textMCurDepartment of Advanced Nursing SciencePregnant women who have anaemia are more likely to experience preterm birth, low
birth weight, perinatal and n eonatal mortality, which is one of the major public health
issues. In the South African province of Mpumalanga, in the Matibidi Village of the
Ehlanzeni District , the study's goal was to explore and identify risk factors for anaemia
in pregnancy. It was do ne using a qualitative approach that combined descriptive and
exploratory designs. The population consisted of pregnant women of age 18 years
years and above. A Non probability purposive sampling method was used because
the participants were aware of the risks associated with pregnancy. Immediately after
receiving permission from the U niversity of Venda Research Ethics C ommittee
( UVREC), the researcher sought permission to access the villages from the Ch ief and
Ward Councillor of Matibiti Village . I n depth one to one interview s were conducted
using a semi structured approach . D ata saturation was reached at participant number
16, however, the researcher continued to interview a total of 20 participants. Fo ur
criteria , dependability, conf i rmability, transferability, and credibility were used
to ensure trustworthiness. Te s ch's six steps were applied to analyze the qualitative
data . The findings showed that various factors in Matibiti Village contribut e to anaemia
in pregnant women. These included the socio economic status, pre existing maternal
chronic conditions, and religious and traditional beliefs and cultural practices of the
participants R ecommendations were made based on the study's findings.
R ecommendations included the need to start administering intravenous supplements
like Ferramed to pregnant women who are anaemic to help improve their haemoglobin
levels; health workers should be aware of religious and cultural practices interfering
with a dherence to the proper pregnant health care so that they emphasi z e the ir
urgency during health talks.NR
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
