An increasing number of researchers have recently shown interest in the relationship between economic growth of a country and its research output, measured in scientometric indicators. The answer is not only of theoretical interest but it can also influence the specific policies aimed at the improvement of a country’s research performance. Our paper focuses on this relationship. We argue that research output is a manifestation of the improvement of human capital in the economy. We examine this relationship specifically in South Africa for the period 1980–2008. Using the autoregressive distributed lag method, we investigate the relationship between GDP and the comparative research performance of the country in relation to the rest of the world (the share of South African papers compared to the rest of the world). The relationship is confirmed for individual fields of science (biology and biochemistry, chemistry, material sciences, physics, psychiatry and psychology). The results of this study indicate that in South Africa for the period 1980–2008 the comparative performance of the research output can be considered as a factor affecting the economic growth of the country. Similarly, the results confirm the results of Vinkler (2008) and Lee et al. (2011). In contrast, economic growth did not influence the research output of the country for the same period. Policy implications are also discussed. 相似文献

Fluorine research has been identified as a priority area in South Africa and the South African Nuclear Energy Corporation
(NECSA) is embarking in an effort to expand its hydrogen fluoride and aluminium trifluoride production capacity. On the eve
of those efforts this article reports the findings of an effort to map and assess fluorine research in South Africa in comparison
to four other countries i.e. Malaysia, Australia, Germany and Italy.
The results of the assessment are aimed at guiding future directions for fluorine research in the country, at identifying
centres of expertise nationally where new research chairs could be established, at identifying international centres of expertise
to be utilised for collaboration and of course for inter-temporal benchmarking of fluorine research in South Africa.
South Africa is identified to be producing a small number of fluorine research publications in comparison to other countries
like Germany and Italy which produce orders of magnitude larger number of publications and in comparison to country’s total
research effort. Furthermore the relevant research effort appears to be dispersed geographically and in disciplinary terms.
Relevant recommendations are provided with particular emphasis on the pluralistic science policy approach followed in the
country. 相似文献

This study assessed the inventive activity through patents registered by South African researchers worldwide using the WIPO database. South Africa is the most prolific producer of patents in the African continent. In this study, the focus was on research priority areas documented in the South African government policy documents rather than the overall inventive output of the country. The research priority areas considered were ICT, nanotechnology, biotechnology, climate change, energy and health. Patents in the areas were compared with the BRICS (Brazil, Russia, India, China and South Africa) countries and Egypt. The comparison was done using the revealed technological advantage sometimes referred to as the specialisation index. It is found that the two African countries have not increased their patent share significantly and are yet to find their specialisation. It was found that while South Africa is doing well in terms of patenting compared to other developing countries, the profile of inventions being patented are not necessarily aligned with the priority areas as documented in government policy. 相似文献

This document provides an analysis of scientometric research in South Africa and it discusses sources of growth in the country’s
research literature in general. South Africa is identified to have limited expertise in the field revealed mainly during the
last decade. However, the country is ranked 21st in the world among the countries publishing in the journal Scientometrics and it is the only African country with such a standing in the field. Identification of the forces affecting positively the
growth in the number of research publications in the country indicates that the primary incentive fuelling the recent growth
is the new funding formula in the country which subsidizes the universities by more than R100 000 for each publication that
their staff produces. The increase in the number of journals indexed in the ISI Thomson Reuters database and the incorporation
of social sciences at the NRF have also affected the growth of research publications, but to a lesser extent. 相似文献

This article identifies the effects of disinvestment on the R&D activities in South Africa. The importance of the article lies in its relevance for science and trade policy and in the examination of this angle of sanctions against South Africa. The results indicate that foreign owned companies increase their R&D activities as the threat of disinvestment intensifies. The same phenomenon applies to the new management of companies which disinvest. A side finding of importance is the fact that only a small proportion (3%) of the R&D activity in the country is undertaken by foreign owned companies. A number of explanations are offered for the observed behaviours. 相似文献

Is HIV/AIDS in Africa distinct? What can we learn from an analysis of the literature? 总被引:1,自引:0,他引:1
This paper investigates, through an analysis of the published literature, the notion held by several people that HIV/AIDS
in Africa is unique. Using co-word and multidimensional scaling (MDS) analyses of MEDLINE-extracted HIV/AIDS records, this
study used five lists of terms to investigate the related-ness of various factors and diseases to HIV/AIDS. The lists consisted
of risk factors, sexually transmitted diseases, tropical diseases, opportunistic diseases, and pre-disposing factors. Data
(i.e. words.txt — consisting of keywords/phrases describing the aforementioned factors and diseases; and text.txt — containing
HIV/AIDS papers’ titles) were analyzed using TI computer-aided application software, developed by Leydesdorff. Results revealed
that several factors and diseases that are pre-dominant in Sub-Saharan Africa exhibited strong and high pattern of co-occurrences
with HIV/AIDS, implying close associated-ness with the epidemic in the region. Further areas of research, whose results will
be used to make conclusive observations and arguments concerning the uniqueness of HIV/AIDS in Sub-Saharan Africa, are recommended. 相似文献

This study is an attempt to explain a reliable numerical analysis of a stochastic HIV/AIDS model in a two‐sex population considering counselling and antiretroviral therapy (ART). The authors are comparing the solutions of the stochastic and deterministic HIV/AIDS epidemic model. Here, an endeavour has been made to explain the stochastic HIV/AIDS epidemic model is comparatively more pragmatic in contrast with the deterministic HIV/AIDS epidemic model. The effect of threshold number H * holds on the stochastic HIV/AIDS epidemic model. If H * < 1 then condition helps us to control disease in a two‐sex human population while H * > 1 explains the persistence of disease in the two‐sex human population. Lamentably, numerical methods such as Euler–Maruyama, stochastic Euler, and stochastic Runge–Kutta do not work for large time step sizes. The recommended structure preserving framework of the stochastic non‐standard finite difference (SNSFD) scheme conserve all vital characteristics such as positivity, boundedness, and dynamical consistency defined by Mickens. The effectiveness of counselling and ART may control HIV/AIDS in a two‐sex population.Inspec keywords: diseases, stochastic processes, epidemics, patient treatment, finite difference methodsOther keywords: two‐sex human population, antiretroviral therapy, competitive numerical analysis, stochastic HIV‐AIDS epidemic model, structure preserving framework, stochastic nonstandard finite difference scheme, SNSFD scheme, deterministic HIV‐AIDS epidemic model 相似文献

This article reports the findings of a scientometric analysis of nanoscale research in South Africa during the period 2000–2005.
The ISI databases were identified as the most appropriate information platform for the objectives of the investigation and
have been interrogated for the identification of South African authors publishing in the field.
The article identifies trends over time, major institutional contributors, journals in which South African authors publish
their research, international collaborators and performance in comparison to four comparator countries (India, Brazil, South
Korea and Australia). The major findings of the investigation are as follows: nanoscale research in South Africa is driven
by individual researchers interests up to date and it is in its early stages of development; the country’s nanoscale research
is below what would one expect in light of its overall publication output; the country’s nano-research is distributed to a
number of Universities with subcritical concentration of researchers. 相似文献

This study aims to assess trends in human immunodeficiency virus (HIV) incidence in South Africa, and to assess the extent to which prevention and treatment programmes have reduced HIV incidence. Two models of the South African HIV epidemic, the STI (sexually transmitted infection)–HIV Interaction model and the ASSA2003 AIDS and Demographic model, were adapted. Both models were fitted to age-specific HIV prevalence data from antenatal clinic surveys and household surveys, using a Bayesian approach. Both models suggest that HIV incidence in 15–49 year olds declined significantly between the start of 2000 and the start of 2008: by 27 per cent (95% CI: 21–32%) in the STI–HIV model and by 31 per cent (95% CI: 23–39%) in the ASSA2003 model, when expressed as a percentage of incidence rates in 2000. By 2008, the percentage reduction in incidence owing to increased condom use was 37 per cent (95% CI: 34–41%) in the STI–HIV model and 23 per cent (95% CI: 14–34%) in the ASSA2003 model. Both models also estimated a small reduction in incidence owing to antiretroviral treatment by 2008. Increased condom use therefore appears to be the most significant factor explaining the recent South African HIV incidence decline. 相似文献

Scientific co-authorship of African researchers has become a fashionable topic in the recent scientometric literature. Researchers are investigating the effects, modes, dynamics and motives of collaboration in a continental research system which is in an embryonic stage and in different stages of development from country to country. In this article we attempt to provide some additional evidence by examining both patterns of collaboration at country and continental levels and the scientific disciplines emphasised. Our findings indicate that the continent’s research emphasises medical and natural resources disciplines to the detriment of disciplines supporting knowledge based economies and societies. Furthermore, we identify that the collaborative patterns in Africa are substantial higher than in the rest of the world. A number of questions related to research collaboration and its effects are raised. 相似文献

The importance of science in Africa has been gaining the interest of scholars and policymakers alike who find that the relationship between science and development is getting stronger than ever. Science in Africa continues to find its own place in the global world of science. However, there have not been any attempts in recent years to study the production of science in all African countries taken as a whole. In this bibliometric study, science in Africa is analyzed using the publications African countries have produced in the last 15 years i.e. from 2000 to 2015. It is not only the number of publications but also the research areas which are of great importance. Not many recent studies have examined the publication productivity of all African countries. The analysis undertaken here shows that a few countries, namely, South Africa, Egypt, Tunisia, Nigeria and Algeria are the leading countries. These produced the highest number of publications during 2000–2015. At the same time, some of the weakest countries in Africa have strengths in specific research areas and are thus able to contribute to knowledge production in those areas. The findings presented in the paper suggest the implications for development in Africa and the measures which could be taken. 相似文献

This paper compares the position and performance of Africans in international research networks, comparing a well-funded and internationally driven research network against a network developing organically with less funding and oversight. Specifically, we map the co-authorship networks related to African governance and public policy (1) in general and (2) related to HIV/AIDS. In both research networks Africans are well positioned globally, but African authors have lower connectivity and status in the HIV/AIDS network than the general network. Links between authors in different African countries are often bridged by non-Africans. This makes the African research networks vulnerable to shifting funding priorities; and international dropout would fragment the HIV/AIDS network more than the general network. We conclude that funders and researchers should prioritize direct inter-country African collaborations to improve the resilience of African research networks. 相似文献

South Africa has a decade of experience designing and implementing biodiversity offsets. In the absence of explicit national policy on biodiversity offsets, the country has relied on existing legal provisions in environmental law as the basis for offset requirements, supported by provincial guidelines. South Africa’s periodic national biodiversity surveys provide scientifically rigorous quantification and mapping for individual ecosystems and finer scale surveys identify biodiversity priority areas, primed as ‘offset receiving areas’. Yet despite enabling factors the use of offsets has frequently been inadequate to deliver intended biodiversity outcomes. Challenges include: (a) the absence of national policy to drive and shape offset implementation; (b) insufficient capacity to evaluate, design and implement offsets; (c) inconsistent decision-making; (d) problems establishing sustainable financing mechanisms; and (e) inadequate enforcement and monitoring, linked to poor drafting of licencing conditions and/or insufficient capacity to monitor implementation. South Africa’s experience provides valuable insights into the challenges and potential solutions for making offsets work for biodiversity conservation and offers important lessons for the development and implementation of biodiversity offsetting in other developing countries. 相似文献

Apart from a few bibliometrical studies the South African scientific system is a scantly researched area and asking for more empirical evidence. This empirical study of academics and researchers (n = 204) from a selected province of South Africa examines the interrelationship between publication productivity and collaboration, and the sectoral differences between higher education institutions and research institutes. The study highlights the specific context of the scientific system in South Africa with its characteristics features of productivity and collaboration and shows how they are structurally facilitated and hindered. Being a prominent contributor to the development of science in Africa the study offers some interesting findings. 相似文献

In recent years, the term “policy instrument” has been used frequently with regard to R&D policy and innovation policy. This article examines the development of the term as part of a body of research known as “policy design”. Over the last 50 years, there has been substantial progress in setting policy design on a more systematic basis, with the development of established concepts and analytical frameworks, including various taxonomies of policy instruments. However, with just a few exceptions, this body of research seems to have had little impact in the world of R&D policy. The paper reviews the literature on R&D policy instruments, identifies a number of challenges for R&D policy instruments in the light of four transitions and sets out a research agenda for the study of R&D policy instruments, before ending with a number of conclusions. 相似文献

Electronic ceramics represent an important segment of advanced ceramics and will probably constitute a major share of the
advanced ceramic markets at least till 2000 AD. Yet, other than ferrites, this area has not been sufficiently examined in
this country. Therefore, this review covers briefly the science and technology status, the markets and the possible future
projections of these ceramics the world overvis a vis the Indian situation and indicates the scope for indigenous effort in this vital area of electronic components. 相似文献

This paper reports first results on the interplay of different levels of the science system. Specifically, we would like to understand if and how collaborations at the author (micro) level impact collaboration patterns among institutions (meso) and countries (macro). All 2,541 papers (articles, proceedings papers, and reviews) published in the international journal Scientometrics from 1978–2010 are analyzed and visualized across the different levels and the evolving collaboration networks are animated over time. Studying the three levels in isolation we gain a number of insights: (1) USA, Belgium, and England dominated the publications in Scientometrics throughout the 33-year period, while the Netherlands and Spain were the subdominant countries; (2) the number of institutions and authors increased over time, yet the average number of papers per institution grew slowly and the average number of papers per author decreased in recent years; (3) a few key institutions, including Univ Sussex, KHBO, Katholieke Univ Leuven, Hungarian Acad Sci, and Leiden Univ, have a high centrality and betweenness, acting as gatekeepers in the collaboration network; (4) early key authors (Lancaster FW, Braun T, Courtial JP, Narin F, or VanRaan AFJ) have been replaced by current prolific authors (such as Rousseau R or Moed HF). Comparing results across the three levels reveals that results from one level might propagate to the next level, e.g., top rankings of a few key single authors can not only have a major impact on the ranking of their institution but also lead to a dominance of their country at the country level; movement of prolific authors among institutions can lead to major structural changes in the institution networks. To our knowledge, this is the most comprehensive and the only multi-level study of Scientometrics conducted to date. 相似文献

The study used Rasch analysis to investigate the presence of a syndrome of health risk behavior in South African adolescents. A total of 2186 in-school adolescents participated in the study (males = 1077; females = 1119; age range = 12-16 years; median = 13 years). The data are baseline from a longitudinal study of a leisure-based drug abuse and HIV/AIDS prevention program at Mitchell's Plain in Cape Town, South Africa. The adolescents completed a self-report measure on various health risk vulnerabilities, including use of alcohol, tobacco and other drugs (ATOD), co-occurrence of penetrative sex with use of ATOD, health related self-efficacy, personal beliefs about health, peer perceptions, and use of contraceptives. The Rasch analysis calibrated data on 50 items from the aforesaid conceptually distinct health risk domains. Infit and Outfit mean square statistics and principal components analysis of the standardized residuals suggested a fit of the data to the unidimensional Rasch measurement model. The findings support a syndrome view of health risk in teenagers as proposed by problem behavior theory. 相似文献

The paper is a bibliometric study of the publication patterns and impact of South African scientists 1981–96, with special emphasis on the period 1992–96. The subject fields surveyed are Physics; Chemistry, Plant and Animal Sciences; and Biochemistry/Microbiology. Scientists were selected from the ten universities of the Eastern Cape, Western Cape and KwaZulu Natal, which vary considerably, with respect to standards of education, quantity of publications, development and overall progress. The general purpose is two-fold: 1) to observe the publication and citation trends during 1981–96, a period which covers significant policy changes in the country, in particular the end of apartheid 1994; within this context 2) to investigate the patterns used by scientists 1992–96 from these different institutions in publishing the results of their research in the form of conference papers or (inter)national journals. The study collected two sets of data through a scientometric analysis of Science Citation Index and a questionnaire. With the exception of Physics, the results demonstrate a decreasing South African world share, in particular for Plant & Animal Sc. publications, and a similar decline of citations starting in 1986/87. Further, the citation impact relative to the world, after a substantial drop 1985–93 probably representing the international embargo period, in 1994–96 reaches the same level as observed in 1985–89. Also, the study shows that there is a direct relation between academic position, research experience and productivity among South African Scientists in the four scientific disciplines. 相似文献
