Prof Heidi Hudson
Prof Heidi Hudson wants her faculty to embrace the digital era to find that unique ‘KovsieHumanities’.

Ever since her appointment as Dean of the Faculty of the Humanities in March 2018, Prof Heidi Hudson has been on a mission to build relations – and importantly – to find a unique identity for ‘KovsieHumanities’.

“My immediate aim is to consolidate
where things are going well,
and to rectify imbalances and inequities
that developed over time.”
—Prof Heidi Hudson.

 

Prof Hudson is Professor of International Relations with a B2 rating from the National Research Foundation. She was until recently a member of the Committee on the Status of Women in the International Studies Association (ISA), a Global Fellow of the Oslo Peace Research Institute (PRIO) in Norway and is also an elected member of the Academy of Science of South Africa.

 

Critical self-reflection

 

“My immediate aim is therefore to consolidate where things are going well, and to rectify imbalances and inequities that developed over time,” Prof Hudson said. Such a process will require critical self-reflection from all concerned in order to carve out and claim a specific identity and role for the Humanities at the UFS.

 

Research excellence important

 

Research excellence is a major priority for her and plans to enhance research within the faculty will include measures to understand the faculty’s research landscape, addressing uneven productivity and the lack of diversity of our researchers; creating research-ready undergraduate students; increasing and developing postgraduate students; and effectively marketing our Humanities research. 

 

The diversity of the faculty is considered a strength in terms of interdisciplinary and cross-faculty collaboration. “This aspect is also encouraged by the university’s differentiated research strategy where the Humanities will lead and coordinate an African Studies research hub.”

 

Curriculum development and renewal, together with space to actively engage with discipline-specific questions on the decolonisation of the curriculum, is a key priority related to teaching and learning for Prof Hudson. “The approach to curriculum renewal is collaborative, with the recent formation of two programme committees for the generic degrees,” she said.

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.
