The Faculty of the Humanities webinar series will provide opportunities for future research collaboration.

How does an anthropologist, a linguist, and a health systems researcher collect data during COVID-19 when human interaction is limited? Speaking at the first webinar hosted by the Faculty of the Humanities on Fieldwork in the time of COVID-19, Prof Deborah Posel, Research Professor in Sociology, said, “Lockdown impacted social sciences just as much. For us it was a lockout from people, libraries, and field research.” 

“The benefits (of the webinar) for Humanities research are obvious. Research in the Humanities differs a lot from research in other disciplines such as Natural Sciences; it happens in silos and not as a group focused,” said Prof Heidi Hudson, Dean of the Faculty of the Humanities. This webinar series will provide a platform to engage, but also for inter-departmental and inter-disciplinary research in the faculty. “Using this platform to engage and talk about our shared experiences will help bring researchers together and to reflect on our own experiences,” Prof Hudson said. 

Academics from different departments in the faculty shared how the COVID-19 lockdown affected their research projects. They were Dr Gladys Kigozi, Senior Researcher in the Centre for Health Systems Research and Development (CHSR&D), Dr Kristina Riedel from the Department of Linguistics and Language Practice, and Prof Joy Owen from the Department of Anthropology

Different approaches implemented 

Centre for Health Systems Research and Development
Research in the CHSR&D focuses mainly on in-person research. “COVID-19 has diminished the interaction between researchers and participants, and it threatened the quality of data gathering,” Dr Kigozi said. Field activities were thus suspended for six months, which compromised the timeline of projects.  

The CHSR&D aligned their projects with COVID-19 regulations and had virtual consolidations with the Free State Department of Health, while advertising research through health-care workers and social media.

Department of Linguistics and Language Practice 
For Dr Kristina Riedel, COVID-19 was not the proverbial nail in the coffin of linguistics research. There is great body of spoken, signed or written language that has been transcribed. “Linguists may also study public or private online data or printed texts such as newspapers, social media, and Bible translations,” Dr Riedel said. 

Language documentation usually happens with a researcher interacting with a speaker or group of speakers, which is then recorded in a high-quality, low-noise environment. Just like Anthropology, the best form of understanding data comes from in-person documentation. “We often need to work with people who are not connected to online spaces, such as the elderly and marginalised communities,” Dr Riedel said. Researchers sometimes need to be immersed in the community when recording takes place.

Department of Anthropology 
Prof Joy Owen provided perspective on how Anthropology as a discipline and anthropologists have been impacted by the lack of human interaction, which is what Anthropology is essentially about. “Anthropology, as founded in the early 20th century, is a fully immersive experience. Body, mind, psyche, and spirt were employed to understand the other (people),” Prof Owen said in her opening remarks. The anthropological encounter could thus not be socially and physically distant. 

The continuous shift to virtual interaction is not an ideal practice. “A video call, however initiated, cannot provide access to the daily nuances of life,” Prof Owen said. The video call/interview cannot replace the in-person ‘hanging out.'

Harvard couple to present lectures on Biostatistics and Mathematics at the UFS
2015-12-07


Professor Donald Rubin

Prof Donald Rubin (John L. Loeb Professor of Statistics at Harvard University) and Elizabeth Zell (MStat - mathematical statistician in the Division of Bacterial Diseases) will visit the University of the Free State (UFS) where they will present lectures on their respective work.

Over his prestigious academic career, Prof Don Rubin’s 400 publications and 13 books have earned him around 180 000 citations at an h-index of 113. He is one of the most cited statisticians/mathematicians/economists/psychologists in the world over the last 10 -15 years. He has supervised 35 PhD candidates as sole-supervisor, 17 more as co-supervisor, with a further eight in the pipeline.

Prof Rubin who will meet with UFS academics in the Department of Mathematics and Actuarial Sciences will also deliver a lecture: Rerandomisation to improve covariate balance in experiments.

Randomised experiments are the “gold standard” for estimating causal effects, yet in practice, chance imbalances often exist in covariate distributions between treatment groups. If covariate data are available before units are exposed to treatments, these chance imbalances can be mitigated by first checking covariate balance before the physical experiment takes place. Provided a precise definition of imbalance has been specified in advance, unbalanced randomisations can be discarded, followed by a rerandomisation. This process can continue until a randomisation yielding balance according to the definition is achieved. By improving covariate balance, rerandomisation provides more precise and trustworthy estimates of treatment effects.

Prof Rubin received an honorary professorship from the Faculty of Natural and Agricultural Sciences at the UFS.


Elizabeth Zell

The lecture will take place on:
Date: Tuesday 8 December 2015
Time: 16:00
Venue: Albert Wessels Auditorium, Bloemfontein Campus

Zell earned her Master’s degree in Statistics at North Carolina State University, and for more than two decades, was an active bio-statistical researcher in various offices of the Centers for Disease Control (CDC). Since 2013, she has been the Principal Statistician and President of Stat-Epi Associates, Inc. Her 150+ publications have earned her 14 500 citations at an h-index of over 50. She is a Fellow of the American Statistical Association, and, in 2010, she received the Statistics Section Government Award for outstanding contributions to statistics and public health by the American Public Health Association. During her career at the CDC, she earned more than 20 CDC research awards and honours.

She will deliver two lectures at the UFS. The first is entitled A Potential Outcomes Approach to Documenting the Public Health Impact of the Introduction of PCV13 for the Prevention of Invasive Pneumococcal Disease. The topic of her second lecture is: Assessing the Effectiveness of Intrapartum Antibiotic Prophylaxis for Prevention of Early-Onset Group B Streptococcus Disease through Propensity Score Design

Elizabeth’s lectures will take place on:
Date: Wednesday 9 December 2015
Time: 10:45 and 13:00
Venue: West Block 111, Bloemfontein Campus
