Prof Catherine Comiskey, a professor in Healthcare Statistics from the School of Nursing and Midwifery at Trinity College Dublin and Academic Director of CHARM-EU, presents a lecture on building a research career with global impact to members of the UFS Transformation of the Professoriate Mentoring Programme.

A visiting scholar from Trinity College Dublin in Ireland visited the University of the Free State (UFS) to work with staff members from the UFS Transformation of the Professoriate Mentoring Programme on identifying collaborations, writing, and building a research career.

Prof Catherine Comiskey, a professor in Healthcare Statistics from the School of Nursing and Midwifery at Trinity College Dublin and Academic Director of CHARM-EU – an EU-funded academic programme – held a writing retreat for participants in the Transformation of the Professoriate Mentoring Programme in the last week of June. She also worked with individual members to identify potential European and UK collaborators on various research projects. On Friday 30 June, she presented a lecture on building a research career with global impact.

Encouraging staff members

According to Dr Henriëtte van den Berg, Manager: Transformation of the Professoriate Mentoring Programme, Prof Comiskey encouraged colleagues to develop a research and publication strategy to ensure that they optimise the work they are doing, to look for opportunities to collaborate with colleagues across different disciplines, and to work together on publications and the supervision of postgraduate students.

“She also emphasised the importance of collaborating with people in industry, as they often have a rich source of data that is publishable. She highlighted the importance of being an ethical researcher. The workshop participants benefited from her passion and broad knowledge to start planning collaborations and to reflect on how they can make the work they are already doing work more for them. A group of workshop participants has already started working on a systematic review that they will conduct in collaboration with Prof Comiskey,” said Dr Van den Berg.

Share expertise

Prof Comiskey facilitated online writing interventions for the colleagues of the mentoring programme during COVID-19 lockdown restrictions. She was invited to the campus to share her expertise in quantitative methodology and transdisciplinary work.

Prof Comiskey completed a PhD in Mathematics and coordinates many interdisciplinary research teams, comprising applied mathematicians, statisticians, psychologists, medical doctors, sociologists, anthropologists, nurses, computer scientists, and healthcare employees. She has been selected as one of five international experts nominated by the European Commission to serve on the International Scientific Committee of the European Monitoring Centre for Drugs and Drug Addiction.

She has 30 years’ experience of teaching, research, postgraduate supervision, and teaching to specialists and non-specialists in all areas of applied statistics, mathematics, and epidemiology. She is also a seasoned academic leader, having served as Research Director at Trinity College, Dublin for many years.

CHARM-EU is an EU-funded academic programme spanning five European universities to develop, run, and evaluate a new EU-wide model for Universities of the Future. This involves a new transdisciplinary master’s degree that addresses the Sustainable Development Goals (SDG).

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
