Dr Martin Clark, the founder of the MAGIC (Multi-purpose Aerial Geological Image Classification) initiative. MAGIC can obtain geological and structural information that is critical for making informed decisions in exploration and mineral extraction processes.

Mining has historically been described as a boom-and-bust industry, where fluctuations in mineral prices could result in extreme success or bankruptcy. Successful mining companies closely monitor assets/expenditures, risks, and other parameters associated with their business to best ensure their longevity. In most mineral industries, there are a few competitors that dominate the delivery of a mineral resource. As a result, technological development, along with other factors, are critical to ensure that these companies’ business remains viable and protected.

This is according to post-doctoral fellow in the Department of Geology, Dr Martin Clark.

Drone technology: better, faster, safer

He says technological development in mining generally translates to how a company can extract a resource from the ground better, faster, and safer. 

Dr Clark believes the rapid development of drone technology represents a shift in the toolbox that mining companies can employ.

“Drones can collect a great deal of data randomly over vast or small areas within hours, historically accomplished by mapping campaigns which can last months to years. Drones can also collect data in areas which are difficult and dangerous for humans to get to. These include cliff faces or rock walls that are difficult and dangerous to get close to, as well as stretches of land where dense vegetation, inaccessible terrain, and even atmospheric dangers become factors which reduce or modify the scope of exploration work,” he said. 

Expanding application of drones

Dr Clark’s work specifically focuses on expanding the applications for which drones are used. “I assess what and how good the imaging capabilities of drones are, use the imagery to generate 3-D models to drive scientific observation, and yield results which can help companies to extract resources. This initiative is called MAGIC (Multi-purpose Aerial Geological Image Classification),” he said. 



“MAGIC aims to collect geological and structural information that is critical for making informed decisions in exploration and mineral extraction processes,” he added.

Dr Clark is not only the founder of MAGIC; he also drives multiple aspects of the initiative including education, research, and business development. 

In 2013, when he was busy with his doctorate, there was already a spark of interest in using drones to address geological questions. At that time, Dr Clark was working with remotely sensed high-resolution LiDAR imagery to better understand geological structures at the Sudbury Mining Camp in Canada. The interest became a reality in 2018, when he applied this initiative during his post-doctoral fellowship at the UFS.

Now and the future

“At present, there are no direct mining projects underway, but projects are expected to begin in 2020. Drone operation and image-analysis techniques are currently being refined for industry,” he said. 

Besides his work with drones, Dr Clark also work in the fields of structural geology, remote sensing, and geospatial data analysis.

Code-switching, tokenism and consumerism in print advertising
2014-10-27

Code-switching, linguistic tokenism and modern consumerism in contemporary South African print advertising. This is the current research focus of two lecturers from the Faculty of the Humanities at the UFS, Prof Angelique van Niekerk and Dr Thinus Conradie.

The act of switching between two or more languages is replete with socio-cultural meaning, and can be deployed to advance numerous communicative strategies, including attempts at signalling cultural familiarity and group affiliation (Chung 2006).

For advertising purposes, Fairclough’s (1989) seminal work on the ideological functions of language remark on the usefulness of code-switching as a means of fostering an advertiser-audience relationship that is conducive to persuasion. In advertising, code-switching is a valuable means with which a brand may be invested with a range of positive associations. In English-dominated media, these associations derive from pre-existing connotations that target audiences already hold for a particular (non-English) language. Where exclusivity and taste, for example, are associated with a particular European language (such as French), advertising may use this languages to invest the advertised brand with a sense of exclusivity and taste.

In addition, empirical experiments with sample audiences (in the field of consumer research) suggest that switching from English to the first language of the target audience, is liable to yield positive results in terms of purchase intentions (Bishop and Peterson 2011). This effect is enhanced under the influence of modern consumerism, in which consumption is linked to the performance of identity and ‘[b]rands are more than just products; they are statements of affiliation and belonging’ (Ngwenya 2011, 2; cf. Nuttall 2004; Jones 2013).

In South African print magazines, where the hegemony of English remains largely uncontested, incorporating components of indigenous languages and Afrikaans may similarly be exploited for commercial ends. Our analysis suggests that the most prevalent form of code-switching from English to indigenous South African languages represents what we have coded as linguistic tokenism. That is, in comparison with the more expansive use of both Afrikaans and foreign languages (such as French), code-switching is used in a more limited manner, and mainly to presuppose community and solidarity with first-language speakers of indigenous languages. In cases of English-to-Afrikaans code-switching, our findings echo the trends observed for languages such as French and German. That is, the language is exploited for pre-existing associations. However, in contrast with French (often associated with prestige) and German (often associated with technical precision), Afrikaans is used to invoke cultural stereotypes, notably a self-satirical celebration of Afrikaner backwardness and/or lack of refinement that is often interpolated with hyper-masculinity.
