A bibliometric study of the publication patterns of South African scientists.

Jacobs, Daisy. January 1998 (has links)
One of the legacies of the apartheid system was the discrepancy in funding and support for various activities, including research work in science and technology based on racial grounds. Some institutions of higher learning and research institutes were favoured more than others in terms of resources. Presently, despite the fact that there is national democracy, previously disadvantaged institutions with their culture of minimal research and poor publication output continue to produce inadequate quantities of research and publications while the historically developed universities are at the forefront of research and publication.This research is a bibliometric study of the publication patterns of South African scientists. The subjects were academic scientists from ten selected universities of the Eastern Cape, Western Cape and KwaZulu Natal, which vary considerably, with regard to standards of education, quantity of publications, development and overall progress. The general purpose of this study was to investigate the patterns used by scientists in publishing the results of their research, provide valuable information and play a significant role in evaluating the research and publication patterns of scientists from these different institutions The study collected two sets of data through lists of publications and a questionnaire. The questionnaire was pretested and the comments of the respondents enabled the investigator to make the necessary revisions in the subsequent questionnaire. The questionnaire was sent to 350 full-time academic scientists in the departments of physics, chemistry, botany, zoology and biochemistry / microbiology in the selected universities. Out of the 350 scientists, 174 responded. Twenty one returns were discarded, hence only 153 were used in the data analysis. Further data was obtained from the Science Citation Index and the Foundation for Research Development. Data were analysed using descriptive statistics, one way ANOVA and Pearson Chi-Square test. The results obtained in this study showed that the five null hypotheses were rejected. It was found that there was a : - • direct relation between academic rank and productivity; academic status and productivity. • direct relation correlation between prestige and productivity. • higher impact of "A" grade scientists over non-"A" grade scientists. • significant difference in productivity between areas of science that are funded and areas which receive little or no funding. / Thesis (Ph.D.)-University of Natal, Pietermaritzburg, 1998.

A comparative analysis of the coverage of science news in Cape Town newspapers

Turner, Gillian Kim 03 1900 (has links)
Thesis (MPhil(Journalism))--University of Stellenbosch, 2008. / The 21st century is less than a decade old, but it is already evident that South Africans will need to improve their scientific literacy (that is, their knowledge about science, the environment and health) if they are to become active citizens in a world which is dominated more and more by complicated scientific and technological advances. It is a world in which average people are increasingly required to understand and make appropriate local decisions regarding numerous scientific debates, including alternative energy sources, climate change and new medical techniques. For most South Africans, the press is their main source of science news. Thus, a huge responsibility rests on the shoulders of newspaper journalists to empower their readers with scientific knowledge and to share the excitement that comes from discovering more about how the universe works. It is within this context that the question arises as to how Cape Town’s newspapers cover science news. Having determined from a review of the literature that a large knowledge gap existed in this field, it was decided to conduct research about science coverage in three daily newspapers (the Cape Argus, the Cape Times and Die Burger) and three weekend newspapers (the Saturday Argus, the Sunday Argus and the Saturday edition of Die Burger) in Cape Town. The quantitative research method of content analysis was employed in order to provide statistical evidence for the study’s problem statement, namely that science news is covered very differently in the six newspapers. This exploratory comparative analysis formed the bulk of the research. The qualitative research methods of surveys and in-depth interviews with the newspapers’ specialist science writers were then used to address the thesis of the study, namely that the science writers are “gatekeepers” (as predicted by the theoretical model of gatekeeping) and that their education, knowledge, interests, beliefs about science, attitudes towards their reporting, and interactions with editors within the newspaper structures determine the science coverage in their newspapers. Thus, this study asks (primarily) what science is covered, and (secondarily) why. The content analysis yielded a wealth of information which confirmed that the six newspapers cover science news very differently, while the surveys and interviews with the science writers validated the prediction that they are the dominant (but not the only) influence on the coverage of science in their newspapers. This study’s goal is to provide a comprehensive comparative overview of the coverage of science news in Cape Town’s newspapers, which will not only create a foundation for future research, but will also provide useful information for the six newspapers, their science writers and editors. Key words: Cape Argus, Cape Times, Cape Town, Die Burger, environment, gatekeeping, health, journalism, media, newspaper, reporter, Saturday Argus, science, South Africa, Sunday Argus, technology.

A bibliometric study on HIV/AIDS literature in South Africa from 1982-2002.

Mitha, Sara Bibi. January 2003 (has links)
The pandemic of HIV/AIDS has been felt by nations throughout the world. It is a well-known fact that the AIDS epidemic is catastrophic in sub Saharan Africa, which heads the list of the most affected regions. As the epidemic imposes a strain on the already limited resources, a better understanding of the disease is continuously being sought out. This understanding is enhanced with better information dissemination. The present research aims to assist the information requirements of HIV/AIDS researchers in the country through a bibliometric study. The present study comprised an investigation of the patterns of authorship and publications of academic institutions in the sciences, medical institutions and affiliated organizations in South Africa, focusing on HIV/AIDS literature for the two decade period, 1982-2002. Published literature in the sciences and medicine from three internationally recognised databases were used for the assessment. They were: AIDSearch, lSI Science Citation Index Expanded and MEDLINE (OVID). A total of 2 281 documents formed the basis for the assessment. The results of the study are presented, as are their consequences for researchers and policy makers. Some recommendations are provided for the developers and designers of databases. The results of the study demonstrate exponential growth in the literature as might be expected. Because of the multidisciplinary nature of the disease, research is scattered in a variety of discipline-based journals. Researchers publish mainly in journals and the South African Medical Journal is the most productive in the field of HIV/AIDS. Collaboration in research on the subject is evident. The results also demonstrate that South African researchers are fast becoming internationally recognized in the field of HIV/AIDS research. The Medical Research Council emerged as the leader in South Africa's research efforts on HIV/AIDS. Of the academic institutions, the University of the Witwatersrand is the most productive institution, followed by the University of Natal. / Thesis (M.I.S.)-University of KwaZulu-Natal, Pietermaritzburg, 2003.

Open access scholarly communication in South Africa : current status, significance, and the role for national information policy in the national system of innovation

De Beer, Jennifer Anne 03 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2005. / ENGLISH ABSTRACT: South African science shows a decline in its global competitiveness in that its scholarly publication rate has not kept pace with that of other countries, both developed and developing. This, together with a decline in publication rate especially among junior South African scholars, suggests a structural problem in the South African national system of innovation. A declining publication rate indicates a problem of knowledge diffusion for South Africa, and hints at a possible knowledge generation problem. This assignment limits itself to the dynamics of knowledge diffusion with specific reference to Open Access scholarly communication. Open Access scholarly communication is an overt intervention regarding knowledge diffusion. The marginalisation of science in and of developing countries, leading to a state of knowledge imperialism and knowledge dependence, is addressed, and it is argued that knowledge diffusion and generation are at the heart of longterm economic growth. This assignment has been structured around two core sections, a theoretical framework based in the literature, and empirical study. The central concepts of scholarly communication and Open Access, national information policy (NIP), and national system of innovation (NSI) are elaborated upon in the theoretical framework (Chapters 2 and 3). The empirical part of this study (Chapters 4 and 5) in turn consist of two parts. Both parts used the survey method, however the first part made use of a questionnaire instrument, and the second part made use of a structured record review. Both empirical studies were used to assess levels of activity and extent of adoption of Open Access within a defined South African scholarly community, one discipline-based, the other institution-based. The aims of this study were two-fold: to assess levels of awareness of and investment in Open Access modes of scholarly communication within defined scholarly communities; and to create a benchmark document of South Africa's involvement to date in various Open Access initiatives. The argument is made for the openness of scholarly systems, and furthermore that the disparate and uncoordinated nature of Open Access in South Africa needs a policy intervention. The policy intervention so identified would exist within an enabling policy environment and would be minimally disruptive to the South African science system. Said policy intervention would constitute a National Information Policy since it would address the storage, dissemination, and retrieval of scholarly research output. This assignment recommends the amendment of the current statutory reporting mechanism - used by scholars to report and obtain publication rate subsidies - which would require that scholars make their research available via an Open Access mode of scholarly communication, and moreover, would require scholars to report on having done so. / AFRIKAANSE OPSOMMING: Die wetenskap as praktyk in Suid-Afrika toon 'n afname in internasionale mededingendheid. Laasgenoemde is sigbaar in die tempo waarteen Suid-Afrikaanse vakpublikasies nie tred hou met dié van ander nasies nie, beide ontwikkelde en ontwikkelende lande. Hierdie afname, gepaardgaande met 'n afname in publikasiegetalle van veral junior navorsers, sou kon dui op 'n strukturele probleem in Suid-Afrika se nasionale innovasiestelsel. 'n Afname in die vakpublikasietempo dui daarop dat Suid Afrika 'n probleem het ten opsigte van die distribusie van kennis. Hierdie werkstuk is beperk tot die dinamiek van kennisdistribusie met spesifieke verwysing na 'Open Access' wetenskaplike kommunikasie. 'Open Access' wetenskaplike kommunikasie is 'n eksplisiete intervensie gemik op kennisdistribusie. Wetenskap binne en vanuit ontwikkelende lande word al hoe meer onbelangrik geag en kennis-imperialisme and kennis-afhanklikheid neem toe. Aan hierdie laasgenoemde aspekte word ook aandag geskenk. 'n Deel van die argument wat geopper word is dat kennisdistribusie en kennis-generering kern aspekte van langtermyn ekonomiese groei is. Hierdie werkstuk bestaan uit twee kern afdelings: 'n teoretiese raamwerk gebaseer op 'n literatuuroorsig, en 'n empiriese studie. Die sentrale konsepte van wetenskaplike kommunikasie en 'Open Access', nasionale inligtingsbeleid, en nasionale innovasiestelsels word beskryf in die teoretiese raamwerk (Hoofstukke 2 en 3). Die empiriese deel van hierdie studie (Hoofstukke 4 en 5) bestaan uit twee dele. Beide laasgenoemde dele maak gebruik van 'n opname as metodiek, maar die eerste deel het gebruik gemaak van 'n vraelys, en die tweede deel het gebruik gemaak van gestruktureerde studie van rekords (in die vorm van Webtuistes). Albei empiriese studies was gebruik om die vlak en mate van aktiwiteit rondom 'Open Access' binne 'n beperkte Suid-Afrikaanse wetenskaplike gemeenskap vas te stel. Hierdie gemeenskappe is gedefinieer óf volgens dissipline óf volgens instansie. Die doel van hierdie werkstuk was veelvoudig: om die vlak van kennis van en betrokkenheid by 'Open Access' inisiatiewe vas te stel binne Suid-Afrika; sowel as om 'n basis-dokument te skep insake Suid-Afrika se betrokkenheid tot op hede by verskeie 'Open Access' inisiatiewe. Die argument vir 'n oop wetenskaplike stelsel word gestel. Verder word geargumenteer dat die lukrake en ongekoordineerde manier waarop 'Open Access' tot dusver in Suid-Afrika bevorder is, daarop dui dat 'n intervensie op die vlak van beleid benodig word. Laasgenoemde beleid sou binne die bestaande beleidsomgewing geformuleer word, en sou relatief min ontwrigting meebring in die huidige Suid-Afrikaanse navorsingsopset. Die spesifieke beleid wat ter sprake is, is die nasionale inligtingsbeleid aangesien dit regulasies daarstel ten opsigte van die berging, distribusie, en herwinning van navorsingsuitsette. Hierdie werkstuk stel voor 'n verandering van die huidige statutêre verslagdoeningsmeganisme - wat gebruik word deur wetenskaplikes om verslag te doen oor hul gepubliseerde navorsing om navorsingsubsidie te kry - wat sou vereis dat wetenskaplikes hul navorsingsuitsette beskikbaar stel via 'n 'Open Access' kanaal, en verder, dat navorsers verslag doen oor laasgenoemde.
