Determinants of Venture Capital Supply in Sub-Saharan Africa
No full textThe purpose of this paper is to determine the variables that influence venture capital supply in Sub-Sahara Africa. The study developed econometric models and examined a 10-year period (2006 to 2015) pertaining to eight (8) Sub-Sahara African countries namely: Botswana, Ivory Coast, Ghana, Kenya, Mauritius, Nigeria, South Africa and Uganda. The empirical model includes six determinants (initial public offering, market capitalisation, unemployment rate, foreign direct investment inflow, inflation rate and trade openness). Secondary data was utilised for the study. The primary sources of data were the World Bank Development indicators and Preqin data base. All the statistical analyses in the study were performed using E-views version 8. Panel data models of pooled, fixed and random effects were employed. The results suggest that there is a significant positive relationship between initial public offering, market capitalisation and venture capital supply. Second, there is no significant relationship between unemployment rate, foreign direct investment inflows, trade openness and venture capital supply. Based on the empirical findings, this study recommends that Sub-Sahara African governments should attempt to develop their economies by improving infrastructure and corporate governance. There is also a need for African countries to develop the equity market.</jats:p
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

No full textThe Entrepreneurial Orientation of Immigrant Entrepreneurs in South Africa
Get PDFThe objective of this study was to measure the entrepreneurial orientation of immigrant entrepreneurs in South Africa. Data was collected through the use of self-administered questionnaires in a survey. The study focused on immigrant entrepreneurs from West Africa specifically, Nigerians, Ghanaians and Senegalese that are business owners in the retail sector and have been in business for at least five years. Because of the difficulty in obtaining the population of immigrant entrepreneurs in the study area, purposive and snowball sampling methods were used. The results indicated that immigrant entrepreneurs are adept at introducing new product lines and also making changes to their product lines. This suggests that immigrant entrepreneurs are innovative. The results also showed that immigrant entrepreneurs are proactive as they have the tendency to be ahead of others in introducing new products. In additions, immigrant entrepreneurs have a strong preference for high risk projects with chances of high return
The Link between Venture Capital Supply Factors and Economic Development in South Africa
No full textThe purpose of this paper is to provide a new theoretical model for the factors that influence the supply of venture capital investment in South Africa. Based on extant literature, the study puts forward a tentative framework to explain the link between venture capital supply factors and economic development. To this point, the paper has established that there is a link between venture capital supply and economic development and the link is mediated by formal job creation in the MSME sector. The framework depicted in Figure 4 shows three key determinants of venture capital supply including the MSME density, the extent to which industrialisation has taken place and the share of natural resource contribution to GDP. While the utility of the framework is limited without empirical evidence, the study draws attention to the need of the South African economy to find mechanisms of increasing formal job creation in the small and medium enterprise sector while simultaneously focusing on increasing the rate of industrialising the economy
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
