In developing an equitable, efficient, coherent and high quality health system in South Africa , there is considerable potential for constructive engagement collaboration and co-operation between the public and the private health care sectors. Both sectors should embrace this opportunity and therefore it is useful to propose some basic guidelines for engagement based on the vision and goals of the national health system.
In deciding whether or not to pursue any new PPI within the health sector, or in evaluating whether an existing PPI should continue or be revised, it is necessary to assess its merits in relation to the achievement of health system goals. Policy Toward Southern Africa , this day unit of study is designed to help high school students learn about the history, geography, and present situation in South Africa and its relationship to the United States. The first of four sections…. Spherule layers in the approximately 3. This interpretation was based, among other arguments, on the enrichment of siderophile elements, especially the platinum group elements.
We made a detailed mineralogical, petrological and geochemical study of spherule bed samples taken from drill cores and underground esposures at the Princeton, Mt. Morgan and Sheba gold mines, as well as surface localities. The macrostructure of each sample from within different spherule layer units shows evidence for multiple more than five events over about 30 cm. The mineralogy provides evidence for extensive hydrothermal and metasomatic alterations of the spherule beds. Geochemical analyses of alternating spherule, shale and chert layers show no correlation between the siderophile elements e.
Furthermore, no significant variation in the content of the siderophile elements was detected between spherule layers and shale layers; however, siderophile element contents are high only in layers containing abundant sulphide minerals and having high As, Sb, Se and Cr contents. We suggest that complex mineralizations, similar to those that have formed the Barberton Archean gold deposits or the Bon Accord deposit, were responsible for the siderophile element enrichments in the spherule beds. Nowhere else in the world have such multiple or even single spherule beds been observed, and none of the numerous known impact craters or the Cretaceous-Tertiary boundary is associated with comparable spherule beds.
Country watch: South Africa. Photo-comics are an ideal format for education of South African youth about acquired immunodeficiency syndrome AIDS given their low literacy rate and the widespread popularity of comic books. The comic tells the story of an adolescent girl who learns her friend committed suicide because she was infected with the human immunodeficiency virus HIV. Roxy learns about AIDS and discusses the risk factors with her friends. Focus group discussions were used to generate story ideas and pretesting of the comic book took place among several student groups.
By July , 30, copies of "Roxy" had been distributed to students, churches, youth groups, civic associations, and organizations working with street children. In addition, the comic was reproduced in a magazine, "Upbeat," that is popular among out-of-school youth. Qualitative evaluation through 8 student focus groups revealed that young people from various cultural backgrounds strongly identify with the themes, characters, and situations depicted in "Roxy. The comic includes a sex education chart with concise condom use instructions. Hydrous komatiites from Commondale, South Africa : An experimental study.
This study examines the emplacement conditions of komatiites in the 3. The komatiites of Commondale are unlike any other komatiites in both their physical structure and chemical nature. Komatiite unit chill margins preserve original komatiite liquid compositions with an Mg of 0. A common feature throughout the komatiite sequence is the presence of orthopyroxene spinifex, where original orthopyroxene crystals are still preserved.
This study used anhydrous and hydrous equilibrium experiments, along with disequilibrium cooling-rate experiments, to quantify the crystallization conditions of the Commondale komatiites. The phase relations were also examined at MPa under H 2O saturated conditions. Additionally, dynamic cooling-rate experiments show that the natural pyroxenes preserve a chemical signature indicative of crystallization and cooling within an inflated flow complex. This range is similar to that estimated for 3.

Health promotion in South Africa. Health promotion first entered the South African health system in The first significant piece of new policy for health promotion in South Africa appeared in the African National Congress ANC health policy document, health care services including reproductive health care.
At the moment, health promotion service delivery is the responsibility of the national, provincial and local governments with provincial and local governments mainly implementing and the National Health Promotion Directorate offering support. Funding for health promotion activities comes from the Department of Health budget allocation by the National Treasury. One major problem for Health Promotion development is infrastructure.
There is significant community participation in South Africa including health promotion policy and strategy document development. Health Promotion research and evaluation is limited. The National Department of Health considers the settings approach to be crucial in driving the progress of health promotion. There are very few trained health promotion specialists either capable or in the position to inform politicians and opinion leaders about the relationship between health and social determinants, and the evidence of effectiveness of health promotion action.
Mechanisms for demonstrating evidence of health promotion effectiveness in terms of health, social, economic and political impact are lacking and occupational standards for health promotion education and training are needed.

This is an area of active mining for diamonds, which were washed downstream from the famous Kimberley Diamond Area, millions of years ago when the river was much larger. The mining is focused on ancient drainages of the Orange River which are currently buried by think layers of sand and gravel.
Scientists are investigating whether these ancient drainages can be seen with the radar's ability to penetrate sand cover in extremely dry regions. A mine, shown in yellow, is on the southern bank of the river in an abandoned bend which is known as an 'oxbow. The large dark area in the center of the image is the Kubus Pluton, a body of granite rock that broke through the surrounding rocks about million years ago. North is toward the upper right.

Examines the extent to which sociopolitical changes that have taken place in South Africa have impacted everyday linguistic interaction and have contributed to language shift from the indigenous African language to English,….
These units of study and learning activities for use in secondary social studies classes will help students better understand the complex situation in South Africa and prepare them to make wise and effective decisions about U. The Flynn Effect in South Africa. This is a study of secular score gains in South Africa. The findings are based on representative samples from datasets utilized in norm studies of popular mainstream intelligence batteries such as the WAIS as well as widely used test batteries which were locally developed and normed in South Africa.
Flynn effects were computed in three ways. Financing Schools in the New South Africa. In almost every dimension, South Africa has undergone dramatic changes since the end of apartheid. Public education in South Africa has been completely transformed from an amalgam of separate and highly unequal educational systems, defined in terms of the race and place of residence of students, into a unified system based on the principle of…. Findings: The paper explores….
The influence of heating over Africa on the South American precipitation climatology, and the influence of South America on Africa , is examined through the application of GCM simulations with idealized boundary conditions and perpetual solstice January and July conditions.

The presence of Africa is associated with a pronounced up to 4 mm day-1 decrease in precipitation in Brazil's Nordeste region during austral summer. Low-level moisture divergence and dry-air advection associated with the downbranch of a Walker circulation induced by heating over southern Africa is amplified over the Nordeste due to the response of the land surface.
The response is much smaller during austral winter due to differences in the heat source over Africa and a reduced sensitivity in the surface heat balance over tropical South America. In July, a Rossby wave train generated over South America induces a response in the surface temperature of Africa that leads to stronger precipitation in central and western Africa.
This study suggests a zonal mode of variability for South American and African circulation and precipitation fields.

The resulting perturbations depend as much on land surface atmosphere interactions as on the direct forcing from the adjacent continent, and the mechanisms are highly nonlinear. South Africa Divestiture. Target Report No. Divestiture of university-held stock in U. Namibia [ South -West Africa ].
Namibia, a country of 1,, inhabitants of whom The Namibian Desert was a barrier to European expansion until the late 18th century, when the area came under German and British influence. Efforts to bring about an orderly and peaceful transition to independent status are hampered at present by the lack of parallel progress toward withdrawal of Cuban combat forces from Angola. Beginning in , considerable executive power was transferred from the administrator general appointed by the South African Government to an interim 3-tier system of elected representatives dividing responsibility between central, ethnic, and local authorities.
The judicial structure has separate overlapping systems for whites, westernized blacks and coloreds and for indigenous blacks. Namibian society is highly politicized, with 4 white and about 40 nonwhite political groups. Namibia's economy is dual, with a modern market sector of mining, ranching and fishing producing most of the wealth and a traditional subsistence sector supporting most of the labor force. However, real growth since has been negative because of persistent drought, political uncertainty, low demand for mineral products, and previous overfishing.
Namibia has no separate representation in any international body. The country may have the. Echinococcus felidis in hippopotamus, South Africa. Hydatid cysts of Echinococcus felidis are described from the hippopotamus Hippopotamus amphibius from Mpumalanga Province, South Africa.
Among six hippopotami investigated, hepatic hydatids were found in three. The identification was based on mitochondrial and nuclear DNA sequences. In addition, the rostellar hook morphology was analysed. This is the first morphological description of the metacestode of E. The definitive host of E.
All rights reserved. Phytoplankton bloom off South Africa. NASA image acquired December 26, Off the coast of South Africa , near where the South Atlantic meets the Southern Indian Ocean, a massive summer phytoplankton bloom colored the waters with a swirl of turquoise, green and white in late December Although this circular bloom has the appearance of a precious antique gaming marble, it is actually the result of millions of tiny plant-like organisms phytoplankton which are growing where nutrient-rich waters mix together.
Each spring and summer, lengthening sunshine comes to the southern oceans, providing light to spur the growth of these microscopic plants. The lengthening light also melts sea ice, which can release additional nutrients into the sea. Blooms such as this one become a banquet for krill, fish and other marine species which survive in these cool waters. Using a geographical information system to plan a malaria control programme in South Africa. Booman, M. In Mpumalanga province, South Africa , rational planning has historically been hampered by a case surveillance system for malaria that only provided estimates of risk at the magisterial district level a subdivision of a province.
METHODS: To better map control programme activities to their geographical location, the malaria notification system was overhauled and a geographical information system implemented. The introduction of a simplified notification form used only for malaria and a carefully monitored notification system provided the good quality data necessary to support an effective geographical information system. RESULTS: The geographical information system displays data on malaria cases at a village or town level and has proved valuable in stratifying malaria risk within those magisterial districts at highest risk, Barberton and Nkomazi.
Matching malaria control measures to specific strata of endemic malaria has provided the opportunity for more efficient malaria control in Mpumalanga province.
