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.

Plant-strengthening agent enhances natural ability of plants to survive
2015-07-27

Drought, diseases, and fungi. These are factors that farmers have no control over, and they often have to watch despondently as their crops are damaged. In addition, the practice of breeding plants in special and strictly-controlled conditions, has resulted in crops losing the chemical ability to protect themselves in nature.

Researchers in the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS) have developed an organic agent that restores this chemical imbalance in plants. It enables the plant to build its own resistance against mild stress factors, and thus ensures increased growth and yield by the plant.

ComCat®, a plant-strengthening agent, is the result of extensive research by the German company, Agraforum AG, together with the UFS. Commercialisation was initially limited to Europe, while research was done at the UFS.

“Plants have become weak because they were grown specially and in isolation. They can’t protect themselves any longer,” says Dr Elmarie van der Watt from the department.

Dr Van der Watt says that, in nature, plants communicate by means of natural chemicals as part of their resistance mechanisms towards various stress conditions. These chemicals enable them to protect themselves against stress conditions, such as diseases and fungi (biotic conditions) or wind and droughts (abiotic conditions).

Most wild plant varieties are usually well-adapted to resist these stress factors. However, monoculture crops have lost this ability to a large extent.

The European researchers extracted these self-protection chemicals from wild plants, and made them available to the UFS for research and development.

“This important survival mechanism became dormant in monoculture crops. ComCat® wakes the plant up and says ‘Hey, you should start protecting yourself’.”

Research over the last few years has shown that the agent, applied mostly as a foliar spray, subsequently leads to better seedlings, as well as to growth, and yields enhancement of various crops. This is good news for the agricultural sector as it does not induce unwanted early vegetative growth that could jeopardise the final yield ? as happened in the past for nitrogen application at an early growth stage.

“The use of synthetic agents, such as fungicides which contain copper, are now banned. Nowadays, options for natural and organic agriculture is being investigated. This product is already widely used in Europe, but because farmers are often swamped by quacks, the South African market is still somewhat sceptical.”
