ScholarGPS honours Prof Hendrik Swart as highly ranked scholar

04 June 2024 | Story Leonie Bolleurs | Photo Kaleidoscope Studios

ScholarGPS awarded Prof Hendrik Swart, Senior Professor in the Department of Physics at the University of the Free State (UFS), Highly Ranked Scholar status.

ScholarGPS celebrates Highly Ranked Scholars™ for their performance in various fields, disciplines, and specialties. Prof Swart’s prolific publication record, the high impact of his work, and the outstanding quality of his scholarly contributions have placed him among the top 0,05% of all scholars worldwide.

Prof Swart received Highly Ranked Scholar status (Lifetime) for ranking 16th in the discipline of Phosphor. Highly Ranked Scholars™ – Lifetime refers to distinguished authors, including those who are currently active, retired, or deceased. These scholars are recognised for their exceptional lifetime scholarly contributions, placing them in the top 0,05% of all scholars. Their achievements are evaluated across four categories: overall (across all fields), within their specific field of study, within their particular discipline, and across all specialties they are associated with.

Additionally, Prof Swart received Highly Ranked Scholar status (prior five years) for ranking first in Condensed Matter Physics, 42nd in Physics, 155th in Sensor, 207th in Physical Science and Mathematics, and 969th in all fields.

Scientific profile and credibility

ScholarGPS is a California-based company that applies artificial intelligence, data mining, machine learning, and other data science techniques to its massive database of more than 200 million publications and 3 billion citations to rank more than 30 million scholars and 55 000 institutions worldwide. They categorise more than 200 million scholarly publications into specific academic specialties. These specialties are further organised into 177 disciplines and 14 overarching fields. As a result of this extensive classification effort, scholars who are considered highly ranked within their respective fields can now be identified with greater precision. This identification is done not only within each academic specialty, but also across disciplines and fields, providing a comprehensive view of scholarly achievement and expertise. This system allows for the identification of top scholars within various areas of academic research in a way that was not possible before.

Prof Swart, who is an NRF B1-rated researcher, currently also holds the SARChI Research Chair: Solid-state Luminescent and Advanced Materials (2023-2027). On receiving this award from ScholarGPS, he says it is always a privilege to be recognised as one of the top scholars in your specific field, especially at this late stage of his career.

Professionally, Prof Swart says this award may boost his scientific profile and credibility in the academic community, potentially leading to more collaborations and partnerships.

In the field of condensed matter physics, the impact of his work is specifically noteworthy in the study of defects and impurities within semiconductors, along with their practical applications in optoelectronic devices. Moreover, his significant contributions extend to understanding optical and electronic properties at the nanoscale, bearing implications for the development of semiconductor technology, including light-emitting diodes (LEDs), photovoltaic cells, and quantum dots.

Primarily focused on mentorship

He believes his successes in physics and advances in understanding the universe are the result of a combination of variables, including innovative research, collaboration and networking, mentorship, effective communication, persistence, and resilience. “I am primarily focused on mentorship, which is critical to developing the next generation of physicists and creating a supportive environment for learning and discovery, as well as conducting groundbreaking research and making novel discoveries that are critical to pushing the boundaries of physics. I am always searching for opportunities to collaborate with other scholars, both inside and outside my discipline, which will result in constructive exchange of ideas, interdisciplinary discoveries, and collective problem solving.”

The launch of a unique conservation project

2011-06-06

Our Department of Animal, Wildlife and Grassland Sciences launched a very special pilot project at Woodland Hills Wildlife Estate in Bloemfontein on Friday 03 June 2011, which aims to eventually aid in the conservation and study of one of Africa’s most graceful animals.

The project aims to provide the scientific basis needed for making future decisions in the best interests of the giraffe in the Kgalagadi Transfrontier Park in the Northern Cape and involves collaring and monitoring the behaviour and movement of these animals via GPS.

Based on the public interest in the giraffe and the increased impact of the growing giraffe population on the vegetation in the area, SANParks has been considering the translocation of a number of Kgalagadi giraffe. Due to limited information regarding their adaptation success and potential impact on their new environment, thorough planning and subsequent monitoring of the species is required.

Mr Francois Deacon from our university decided to undertake a PhD study to address the existing challenges. This will be the first study of its kind, undertaken on giraffe.

He says he decided on this project because of his love for animals and conservation. “There are nine sub-species of giraffe and seven of these are already endangered. I want to involve people and make them aware of the plight of the animals and the need for conservation,” he said.

The project kicked off on Friday morning, with a group of students and curious nature-lovers tracking a herd of giraffe at Woodland Hills. The challenge laid in identifying one of the animals which could easily be collared with a GPS device, tranquilising it, and applying the device, without harming the animal.

After a young bull was identified, it was up to Dr Floris Coetzee, a veterinarian, to get close enough to the animal to tranquilise it, and to the group of students to catch it and hold it down. All this was done perfectly and the animal was fitted with its new collars. The collars were designed and made by Mr Martin Haupt, who gained extensive experience in the design of similar collars for other research studies.

Mr Deacon will spend the following two weeks personally monitoring the animal constantly, to ensure that the collars do not cause any discomfort or injury and to determine whether it should be removed or adapted.

It has taken Mr Deacon over a year to plan the collaring process and the associated study. He says the main challenges in the project are financial, since it will cost approximately R500 000 to run over five years.

Thus far he has been supported by Mr Pieter Malan of Woodland Hills, Mr Cas Kempff of Cas Kempff Consulting Engineers and Prof. Frans Swanepoel of the UFS’ Directorate of Research Development, all of whom have been benefactors of the project.
Information gathered from the pilot project will provide the data to assess how to best fit the collar onto the giraffe to ensure that the animal is comfortable and that the collar will last in the wild. Scientific data will be generated and processed for use by the Woodland Hills Wildlife Estate management.

Should the pilot project be successful, between four and eight giraffe in the Kgalagadi will be tracked using the satellite GPS collars. The GPS collars will enable the constant recording of the location of individual giraffe for up to 2 years. This will allow control and monitoring of the animals in real-time.

The main benefits of the project include, amongst others, improved decision-making, informing tourism development, education and community involvement, improved sustainability and improved cross-border collaboration between South Africa and Botswana.

Anyone who wishes to get involved with the project or get more information, should contact Me. Sonja Buhrmann at sbuhrmann@vodamail.co.za or 0827735768.
