Molecular and biochemical characterisation of transgenic banana lines containing iron uptake and storage enhancing genes
No full textThis thesis investigated the basis for availability of iron (Fe) and zinc (Zn) content in different banana fruits grown in Uganda and Australia. Rather than micronutrient content levels in different banana cultivar, genotype and environment interactions explained much of the differences. Such information should provide important insights for future developments in the biofortification of banana. Bananas consumed in Uganda did not contain sufficient levels of Fe and Zn that meet the nutrient requirements for vulnerable groups
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
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
Incidence and predictors of treatment failure to second line Antiretroviral treatment in a young people living with HIV clinic
No full textA dissertation submitted in partial fulfillment of the requirements for the award of Master of Science in Clinical Epidemiology and Biostatistics of Makerere UniversityBackground: Second line (PI) based regimens are still very expensive in most developing nations yet will be needed soon by the high number of people on ART due to treatment failure. We asked whether socio-demographic, laboratory and treatment data can be used to estimate the incidence of treatment failure on second line based regimens and to predict treatment failure in a young people living with HIV clinic at Baylor-Uganda.
Methods: A retrospective cohort study was carried out on 298 medical records of young people living with HIV receiving second line care and treatment at Baylor-Uganda between the period 2010 and 2013.
Results: During the follow up time of 12 (5-49.0) months, there were 65 (21.8%) primary endpoints (treatment failure). The incidence rate was 18.2 (14.3-23.2) per 100 person years and the predictors that were associated with second line treatment failure were duration on ART medication of 1-2 years (HR=3.485, p=0.009), duration on ART of 3-4 years (HR=4.186, p=0.000), duration on ART of > 5years (HR=7.418, p=0.000), viral load > 1000 cp/ml (HR=3.933, p=0.000) and adherence levels < 95% (HR=2.775, p=0.001).
Conclusion: A relatively high rate of treatment failure was reported from a clinical setup among young people living with HIV/AIDS in Kampala Uganda. Elevated viral load count, poor adherence and duration on ART were the predictors identified to second line treatment failure
Availability, accessibility and use of information and communication technology in management of students’ academic affairs in Makerere University
No full textA thesis submitted in partial fulfillment of the requirements for the award of the Master of Education in Information and Communication Technology Degree of Makerere University.The study was about availability, accessibility and use of ICT in management of students’ academic affairs in Makerere University. This emerged because of the problem that there was mismanagement of students’ academic records despite the technological advancement that had advanced in the University. Such problems include loss of marks, miscalculation of marks to mention but a few. The study intended to establish how ICT affected management of students’ academic affairs. It applied both correlation and cross sectional survey design. Data were collected using semi-structured survey questionnaires and interviews. Correlations were used to determine the extent to which ICT was related to management of students’ academic affairs and a cross sectional survey design was used because data were to be collected at one time from the sample of lecturers and administrators of Makerere University. Findings indicated that internet facilities, computers, management information systems, electronic databases all were available and accessible to administrators, lecturers and students though with restricted access for viewing results, record keeping, setting and marking exams. ICT for registration was used for tracking students’ registration progress by administrators and academic progressing. It was concluded that ICT facilities such as computers Management Information System and internet were the most common used for examination management and they were mainly applied for processing examination results, tracking students' academic progress, grading of students according to their performance, communication between lecturers and heads of department, communication to students via emails. It was again noted that ICT was accessed for communication between administrators and other teaching staff members in the University, for returning results to students online, calculating students’ GPA and CGPA and processing transcripts. Investigation about the level of use of ICT for registration management in Makerere University established that ICT facilities were used for provision of information easily on registration of students, easy monitoring of students’ registration progress, easy comparison of registration status with other data such as students’ academic progress and enhanced time management. So ICTs were reliable compared to the previous manual system. However ICT had not effectively improved collaboration between University administrators, students and the university outside community. Electronic Registration System was more It was recommended that the University authorities should adequately train and acquaint users with ICT skills such as database management, typing and printing, online examination management, skills in management information systems and internet and facilitate them with ICT facilities and University authorities should make it a policy for lecturers to use ICT facilities for examination management. It was also suggested that University authorities should train administrators and provide them with the required facilities like computers, computer software, internet facilities and reliable databases and there must be a formal procedure to be followed to enforce strict use of ICT structures in the University. It was also recommended that a framework of guideline be provided for prior to purchasing an e-registration system, that is, a list of the required specifications be made after consultation with users (administrators) to enable purchase of a reliable ICT structure and initial ICT training for administrators must be undertaken to engender commitment to e-registration initiative and support for new ICT skills acquisition for effective implementation of online registration
