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

Get PDFVariations 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
Strategies to enhance the approach to prostate cancer screening of African men in the Free State
No full textThesis (Ph.D.(Family Medicine))--University of the Free State, 2023: Prostate cancer is a significant public health concern in South Africa, with rising incidence and mortality rates, particularly among African men. Prostate-specific antigen (PSA) screening is a practical method for early detection and improved outcomes. However, it carries the risks of overdiagnosis and overtreatment. Recent studies have shown a more significant net benefit of PSA screening for Black men than the general population. However, there are knowledge, attitude and practice gaps among primary healthcare providers and users, especially Black men, regarding prostate cancer screening. Practical strategies to address these gaps are lacking. This study focuses on vulnerable African men in the Free State Province, South Africa.
: This thesis presents the results of five complementary studies aiming to identify gaps in prostate cancer screening and determine strategies to enhance prostate cancer screening among African men in the Free State Province from the perspectives of primary healthcare providers and users. The first study employed a cross-sectional descriptive design, using case record information and self-administered questionnaires to profile Black South African men with prostate cancer attending a tertiary hospital’s oncology and urology clinics in the Free State Province. The second study used a cross-sectional analytical survey design, administering self-administered questionnaires to assess the knowledge, attitude and practice of primary healthcare providers in the study setting. The third study also employed a cross-sectional analytical survey design, utilising self-administered questionnaires to investigate African men’s knowledge, cultural beliefs and screening intentions regarding prostate cancer screening. Factors associated with their intention to screen for prostate cancer were examined. Quantitative data were analysed using descriptive statistics, and associations were tested using chi-squared or Fisher’s exact tests. The fourth and fifth studies comprised a scoping review and a modified Delphi survey to identify and propose strategies to enhance prostate cancer screening among African men in the study setting, addressing the identified gaps.
: The findings revealed that aggressive prostate cancer is prevalent among African men in the study setting. Poor knowledge and awareness of the disease and low screening uptake were observed. Factors such as dietary habits, lifestyle and presentation time were associated with aggressive disease at diagnosis. Cultural beliefs influenced screening uptake among men. Factors associated with a higher intention to screen included reduced fear, perceived benefits, situational barriers, and perceived risk of developing prostate cancer. Regarding primary healthcare providers, the majority demonstrated poor knowledge (64.8%), neutral attitudes (58.6%) and poor practice (40.0%) related to prostate cancer screening. Female providers, lower cadre nurses and community health workers had lower knowledge scores. Lack of prostate cancer-related continuing education was significantly associated with poor knowledge, negative attitudes and poor practice among healthcare providers. The study proposed strategies to address the identified gaps among African men and primary healthcare providers. Community-oriented approaches involving the active participation of both providers and community members were emphasised. These strategies focused on relevant prostate cancer health education topics in public spaces, employing diverse, comprehensive, user-friendly and culturally sensitive methods.
: This thesis highlights the gaps in prostate cancer screening among African men and primary healthcare providers in the Free State Province, South Africa. Targeted strategies are needed to enhance prostate cancer screening uptake and improve outcomes in this vulnerable population. Implementing the proposed strategies can improve awareness and knowledge of the disease and ultimately enhance screening practices among African men in the study setting
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
