Data on Indigenous traditional knowledge of medicinal plants used by herbalists in treating opportunistic infections among people living with HIV/AIDS in Uganda
No full textIn Uganda, herbalists widely used medicinal plants for treating people living with HIV/AIDS (PLHIV). Different species are mainly used to treat the opportunistic infections that characterise the disease. An ethnobotanical survey was conducted in eight districts of Arua, Dokolo, Mbale, Bushenyi, Iganga, Rakai, Luwero and Kaabong in different parts of Uganda. The data has been disaggregated by district in each column. Each column captures the biodata and number of herbalists interviewed by district. Then a summary of the responses to the key questions asked pertaining to the use of medicinal plants, the signs and symptoms of HIV/AIDS and the indigenous traditional knowledge and associated practices of the herbalists. Data from the individual districts is then synthesised to get a representative picture for the whole country. The data generally show that the herbalists treat HIV/AIDS by symptoms patients present with. An analysis of all the opportunistic infections and their frequency of citation by the herbalists is given. The herbalists are knowledgeable on a wide range of opportunistic infections in HIV/AIDS. The herbalists also generally counsel their patients and encourage them to simultaneous their antiretroviral drugs with herbal treatments. The data also show what the herbalists believe to be the cause of AIDS, in addition to the challenges they face in their practice
Antiviral activity of Ugandan medicinal plants against human immunodeficiency virus type-1 (HIV-1)
No full textThis data set describes data on the antiviral activity of 11 medicinal plant species used to treat people people living with HIV/AIDS in Uganda against-HIV-1. The data was generated from 22 plant extracts were tested against HIV-1 Pseudovirions (PV) HXB2 (IIIB) strain using the human glioblastoma cell line; U87.CD4.CXCR4, transfected with the luciferase firefly reporter gene. The selective inhibition of the growth of HIV-1 PV was measured using the selectivity index. The in vitro cytotoxicity of each of the plant extracts was also evaluated using the AlamarBlue cell viability assay on U87.CD4.CXCR4 cells. The experiments were conducted at the Institute for Medical Microbiology & Virology, University Clinics & Faculty of Medicine, University of Leipzig, Germany and the Fraunhofer Institute for Cell Therapy & Immunology, Leipzig, German
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
