Nanotechnology is a fast-growing scientific research area internationally and is classified as an important emerging research area. In response to this importance, South African researchers and institutions have also increased their efforts in this area. A bibliometric study of articles as indexed in the Web of Science considered the development in this field with respect to the growth in literature, collaboration profile and the research areas that are more within the country’s context. We also looked at public institutions that are more active in this arena, including government policy considerations as guided by the National Nanotechnology Strategy launched in 2005. We found that the number of nanotechnology publications have shown a remarkable growth ever since the launch of the strategy. Articles on nanotechnology have been published in numerous journals, with Electrochimica Acta publishing the most, followed by Journal of Nanoscience and Nanotechnology. These publications fall within the traditional domains of chemistry and physics. In terms of the institutional profile and based on publication outputs over the period reviewed, the Council for Scientific and Industrial Research is a leading producer of publications in nanotechnology, followed by the University of the Witwatersrand – institutions that are both based in the Gauteng Province. There is a high level of international collaboration with different countries within this field – the most productive collaboration is with India, followed by the USA and China, as measured through co-authorship.

Entropy, founded in 1999, is an emerging international journal in the field of entropy and information studies. In the year of 2018, the journal enjoyed its 20th anniversary, and therefore, it is quite reasonable and meaningful to conduct a retrospective as its birthday gift. In accordance with Entropy’s distinctive name and research area, this paper creatively provides a bibliometric analysis method to not only look back at the vicissitude of the entire entropy topic, but also witness the journal’s growth and influence during this process. Based on 123,063 records extracted from the Web of Science, the work in sequence analyzes publication outputs, high-cited literature, and reference co-citation networks, in the aspects of the topic and the journal, respectively. The results indicate that the topic now has become a tremendous research domain and is still roaring ahead with great potentiality, widely researched by different kinds of disciplines. The most significant hotspots so far are suggested as the theoretical or practical innovation of graph entropy, permutation entropy, and pseudo-additive entropy. Furthermore, with the rapid growth in recent years, Entropy has attracted many dominant authors of the topic and experiences a distinctive geographical publication distribution. More importantly, in the midst of the topic, the journal has made enormous contributions to major research areas, particularly being a spear head in the studies of multiscale entropy and permutation entropy.

African Sample

A sample of 163 white, male, English-speaking managers from a diversity of disciplines, functional areas and kinds of business and industry completed self-report scales on job demands, role stressors and social support. Their scores were compared with those of comparable samples from elsewhere, mainly from the USA, for whom data were obtained from published sources. The South African mean of 48,9 hours worked per week was similar to those of comparable groups. On a variety of job demands the South African sample showed a trend towards higher demands, which was interpreted in terms of a shortage of high-level human resources, due to over-utilization of whites and under-utilization of blacks. The trend was towards greater role clarity in the South African sample and no greater role conflict was found. More social support was reported than in the case of Dutch samples but less than in USA samples. A generally positive interpretation was given, with an element of eustress also being present.

Obvious and transparent measures of traditional racism no longer appear to adequately assess anti-black prejudice in more sophisticated samples. This, together with a growing tendency for traditional measures to elicit antagonistic responses from subjects, led in an earlier study to the development and preliminary validation of a South African subtle racism (SR) scale. The current research used a new sample, in which the use of traditional measures of anti-black racism would have been very difficult, to cross-validate the SR scale. It also extended the validation of the SR scale by investigating its association with self-reports of actual interracial behaviour. The findings from 303 white students at the University of the Witwatersrand showed a high level of internal consistency on the SR scale, and a strong correlation with an interracial behavioural intention scale. These findings as well as significant correlations with self-reported interracial behaviour support the validity of the SR scale. Contrary to earlier thinking, the findings also indicate a very powerful relationship between anti-black prejudice and authoritarianism.

Road recycling technology is gradually becoming a research focus in road construction due to natural resource shortages. It is therefore necessary to carry out deep and extensive analysis of the huge amount of publications in the research area of recycling technology in road construction. Based on three databases (Web of Science, Compendex and Scopus) and VOSviewer visualization software, this study conducts a bibliometric analysis of the literature in the field of recycled construction materials in pavement engineering. The global research publications were reviewed to quantitatively identify the literature characteristics. A number of publications, document types, research areas and keywords were used to achieve the general statistics of this reviewed literature. H-index, publication number and citations per publication were used to evaluate the academic contributions by country, institution and journal. The results show that the most productive country and institution for publications are the USA and Chang’an University from China, respectively, followed by China and Wuhan University of Technology. In recent years, researchers have generally paid attention to two main approaches: the application of rubber modified asphalt and the performance enhancement of recycled pavement.
