The Dean of the Faculty of Law invites staff and interested individuals to attend the inaugural lecture of Prof Ulrike Kistner, Department of Public Law, titled The ‘person’ in question – legally, grammatically, philosophically.

Date: 17 March 2022
Time: 17:30
Venue: Equitas Auditorium

To attend the lecture, please RSVP to Refilwe Majola at MajolaRRM@ufs.ac.za

More about the speaker:

Prof Kistner has held teaching positions in Comparative Literature at Wits University, Modern European Languages at UNISA, and Philosophy at the University of Pretoria. She is currently working at intersections between political philosophy, social theory, jurisprudence, and psychoanalytic theory.

Abstract:

A major shift has been noted in constitutionalism and human rights frameworks – from human and civil rights to principles centred on ‘personhood’ and ‘dignity’. This shift calls for closer historical-critical investigation of the status of ‘person’. Roberto Esposito directs this inquiry to a philosophical grammar of the impersonal third person.

My contribution to this inquiry sets in with a probing of Esposito’s propositions, considering the post-apartheid elevation of ‘person’ in constitutionalism and philosophical elaborations of communitarianism. To the extent that the concept of ‘ubuntu’ is embedded in a linguistic ontology developed by Kinyarwanda, my argument will navigate between Rwanda and South Africa in the mid-1990s, and between juridical, moral-philosophical, linguistic, and Africanist notions of ‘ubuntu’ and corresponding claims on African philosophy.

The radical questioning of ethnolinguistic tenets on the part of some African philosophers brings me back to the philosophical grammar of the third person which, far from being confined to study old grammar books, opens alternatives to ethnophilosophical approaches to the ‘person’ in question.

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.
