South African land restitution, by way of which the post-apartheid state compensates victims of racial land dispossession, has been intimately linked to former homelands: prototypical rural claims are those of communities that lost their rights in land when being forcibly relocated to reserves and they now aspire to return to their former lands and homes from their despised ‘homelands’. However, white farmers, who were also dispossessed (although usually compensated) by the apartheid state in the latter’s endeavour to consolidate existing homelands, have lodged restitution claims as well. While the Land Claims Court has principally admitted such restitution claims and ruled upon the merits of individual cases, state bureaucrats, legal activists, as well as other members of the public have categorically questioned and challenged such claims to land rights by whites. Focussing on white land claimaints effected by the establishment of former KwaNdebele, this paper investigates the contested field of moral entitlements emerging from divergent discourses about the true victims and beneficiaries of apartheid. It pays particular attention to land claims pertaining to the western frontier of KwaNdebele – the wider Rust de Winter area, which used to be white farmland expropriated in the mid-1980s for consolidation (that never occurred) and currently vegetates as largely neglected no-man’s-(state-)land under multiple land claims. Being the point of reference for state officials, former white farmers, Ndebele traditionalists, local residents, and other citizens, this homeland frontier is hence analysed as a fateful zone of contestation, in which the terms of a new South African moral community are negotiated.

Few studies exist reporting on long-term exposure of crustaceans to hypercapnia. We exposed juvenile South African rock lobsters, Jasus lalandii, to hypercapnic conditions of pH 7.3 for 28 weeks and subsequently analysed changes in the extracellular fluid (haemolymph). Results revealed, for the first time, adjustments in the haemolymph of a palinurid crustacean during chronic hypercapnic exposure: 1) acid-base balance was adjusted and sustained by increased bicarbonate and 2) quantity and oxygen binding properties of haemocyanin changed. Compared with lobsters kept under normocapnic conditions (pH 8.0), during prolonged hypercapnia, juvenile lobsters increased bicarbonate buffering of haemolymph. This is necessary to provide optimum pH conditions for oxygen binding of haemocyanin and functioning of respiration in the presence of a strong Bohr Effect. Furthermore, modification of the intrinsic structure of the haemocyanin molecule, and not the presence of molecular modulators, seems to improve oxygen affinity under conditions of elevated pCO2.
The pragmatics of computer-mediated communication between South African and Mexican drug traffickers

South Africa and Mexico are ripe with drug trafficking. The gangs and syndicates running the drug businesses in these two countries collaborate occasionally. Communication between these international drug business partners takes place on social media. Their main language of communication is English, mixed with some limited use of Spanish and Afrikaans. The key purpose of the interactions between the South African and Mexican parties is the organisation of their business activities. This study aims at examining how the drug traffickers position each other and themselves regarding their common business interest and how their relationship evolves throughout their interactions. Moreover, it is of interest to look at how these people make use of different social media and their affordances. For this a qualitative analysis of the interaction between two drug traffickers (one South African and one Mexican) on Facebook, Threema and PlayStation 4 was performed. Computer-mediated communication between these two main informants was studied at various stages of their relationship. Results show that at first the interaction between the South African and Mexican drug traffickers consists of interpersonal negotiations of power. The high risk of the drug business and gang/syndicate membership paired with intercultural frictions causes the two interlocutors to be extremely cautious and at the same time to mark their position. As their relationship develops and they gain trust in each other a shift to interpersonal negotiations of solidarity takes place. In these discursive practices diverse linguistic strategies are employed for creating relational effects and for positioning the other and the self. The discursive activities of the interactants are also identity practices. Thus, the two drug traffickers construct identities through these social practices, positioning and their interpersonal relationship.
