ABSTRACT BackgroundSub-Saharan Africa is the region most heavily affected by the HIV/AIDS epidemic. HIV increases the risk of developing cancer but the ascertainment of cancers in patients attending antiretroviral therapy (ART) treatment programs might be incomplete. To estimate the under-ascertainment of cancer we compared incidence rates of AIDS-defining cancers in South African HIV cohorts with and without cancer case ascertainment through record linkage with the National Cancer Registry. MethodsWe used the data of adult (≥16 years) HIV-positive persons receiving care between 2004 and 2011 at one of four ART programs in South Africa. These programs collaborate with the International Epidemiologic Databases to Evaluate AIDS Southern Africa (www.iedea-sa.org) and collected data for AIDS-defining cancers but not for other cancers. To improve cancer ascertainment we probabilistically linked patient records (using first name, surname, age, and gender) from two HIV cohorts with the cancer records of the South African National Cancer Registry. We calculated incidence rates per 100,000 person-years after starting ART for the AIDS-defining cancers, i.e. Kaposi sarcoma (KS), invasive cervical cancer (ICC) and non-Hodgkin lymphoma (NHL). We compared incidence rates before and after inclusion of record linkage identified cancer cases using the attributable fraction of cancers identified with 95% confidence intervals (CI). ResultsA total of 49,207 adults starting ART in South Africa were included. 65% of patients were female, median age at starting ART was 35 years (interquartile range 30-41 years). We identified a total of 471 incident cancer cases. With record linkage the incidence increased from 81 to 292 for KS, from 1 to 119 for NHL and 12 to 497 for ICC per 100,000 person-years. The attributable fraction of cancers identified was 72% (95% CI 63-79%) for KS, 98% (95% CI 94-99%) for NHL and 98% (95% CI 95-99%) for ICC. ConclusionAscertainment of cancer in HIV program data in African settings is incomplete. This case study has shown that probabilistic record linkage to cancer registries is both feasible and essential for cancer ascertainment in HIV cohorts in South Africa.

After several decades of apartheid rule, which denied human rights to the majority of the population on the ground of race and came to be regarded as a crime against humanity, South Africa adopted its first democratic Constitution in the early 1990s. The 1996 Constitution, which succeeded the 1993 interim Constitution, is considered one of the most progressive in the world. In its founding provisions, it states that South Africa is a democratic state founded on human dignity, the achievement of equality, the advancement of human rights and freedoms. The Constitution enshrines fundamental human rights in a justiciable Bill of Rights as a cornerstone of democracy. Unfortunately, in the eyes of a number of politicians, officials and lay-persons, the rights in the Bill of Rights accrue to South African citizens only. Xenophobia, which has been rampant since the end of apartheid, seems to support the idea that foreigners should not enjoy these rights. Foreign nationals have often been accused of posing a threat to South African citizens with regard to employment opportunities. In light of the South African legislation and jurisprudence, this article affirms the position of the South African labour law that foreign nationals are indeed protected by the Constitution and entitled to rights in the Bill of Rights, including the rights to work and fair labour practices.

The purpose of this article is to evaluate the engagement of farm beneficiaries in South Africa in the governance of restituted farms through communal property associations. The South African government has already spent millions of rands on land restitution to correct the imbalance of the past with regard to farm ownership by the African communities. Various methods of farm management to benefit the African society have been proposed, however, with little recorded success. This article argues that the South African post-apartheid government was so overwhelmed by political victory in 1994 that they introduced ambitious land reform policies that were based on ideal thinking rather than on a pragmatic approach to the South African situation. We used qualitative research methods to argue that the engagement of farm beneficiaries in farm management and governance through communal property associations is failing dismally. We conclude that a revisit of the communal property associations model is required in order to strengthen the position of beneficiaries and promote access to land by African communities for future benefit.

ABSTRACT This paper used qualitative methodology to explore the South African government communication and land expropriation without compensation and its effects on food security using Alice town located in the Eastern Cape Province South Africa as its case study. This was done to allow the participants to give their perceptions on the role of government communication on land expropriation without compensation and its effects on South African food security. In this paper, a total population of 30 comprising of 26 small scale farmers in rural Alice and 4 employees from the Department of Agriculture (Alice), Eastern Cape, South Africa were interviewed to get their perception and views on government communications and land expropriation without compensation and its effects on South African food security. The findings of this paper revealed that the agricultural sector plays a vital role in the South African economy hence there is a great need to speed up transformation in the sector.

Field dilution studies were conducted on three “deep” water marine outfalls located along the South African coast to establish the comparibility of actual achievable initial dilutions against the theoretical predicted values and, where appropriate, to make recommendations regarding the applicability of the different prediction techniques in the design of future outfalls. The physical processes along the 3000 km long coastline of South Africa are diverse, ranging from dynamic sub-tropical waters on the east coast to cold, stratified stagnant conditions on the west coast. Fourteen existing offshore marine outfalls serve medium to large industries and various local authorities (domestic effluent). For this investigation three outfalls were selected to represent the range of outfall types as well as the diversity of the physical conditions of the South African coastline. The predicted dilutions, using various approaches, compared well with the measured dilutions. It was found that the application of more “simple” prediction techniques (using average current velocities and ambient densities) may be more practical, ensuring a conservative approach, in pre-feasibility studies, compared to the more detailed prediction models, which uses accurate field data (stratification and current profiles), when extensive field data is not readily available.
