  • In 2008, South Africa had 400 953 educators, which included school teachers and principals. Were they adequate in number and quality for the 12 239 363 learners in ordinary public and independent schools? Is the country’s teacher education system sufficiently geared up to produce the teachers that are required and are sufficient numbers of students being attracted to teaching?

However, in recent years, the popular version of this concept McCarthy’s (1964) 4Ps (product, price, promotion and place) has increasingly come under attack with the result that different marketing mixes have been put forward for different marketing contexts. While numerous modifications to the 4Ps framework have been proposed (see for example Kotler, 1986; Mindak and Fine, 1981; Nickels and Jolson, 1976; Waterschoot and Bulte. 1992) the most concerted criticism has come from the services marketing area.

  • As crop prices increase, the value of the crops being insured increases, which results in higher crop insurance premiums and premium subsidies. For example, the prices of major crops were substantially higher in 2011 than in 2006, and premium subsidies in 2011 (about $7.4 billion) were substantially higher than in 2006 (about $2.7 billion). USDA forecasts that the prices of major crops—corn, cotton, soybeans, and wheat—will continue to be substantially higher than 2006 prices through 2016. Administrative expense subsidies also increased because of higher crop prices.

  • Ooplasmic transfer involves egg retrieval from the woman undergoing IVF and another woman donating ooplasm (the cytoplasm of an egg cell: the material outside the nucleus). The egg is then fertilized with sperm and implanted into the woman intending to become pregnant. The resulting child has DNA from both women because of the mitochondrial DNA present in the ooplasm of the donor, as well as DNA from the sperm provider (partner or donor), and therefore has three genetic parents. It had been used for women whose infertility seemed to stem from the ooplasm in their eggs.

  • African countries have a choice between establishing an agricultural sector founded on broad-based ownership of medium-size farms (much larger than those currently operated and expanding over time) or a dual structure where a few mega farms coexist with many small producers. Given the long-term impacts associated with such choices, clear elaboration of the issues in an informed public debate about the development paths open to a country is needed.

  • Traditionally, the woman displayed has functioned on two levels: as erotic object for the characters within the screen story, and as erotic object for the spectator within the auditorium, with a shifting tension between the looks on either side of the screen. For instance, the device of the show- girl allows the two looks to be unified technically without any apparent break in the diegesis. A woman performs within the narrative, the gaze of the spectator and that of the male characters in the film are neatly combined without breaking narrative verisimilitude.

  • Access to basic services and mobility are both enhanced by public transportation and street connectivity (i.e., streets lead to other streets and stores, rather than just ending in cul-de-sacs). Having access to a car, or the use of mass transit, may enable greater mobility and utilization of local resources. Street connectivity may result in smaller walkable neighborhoods and create the opportunity to walk, both recreationally and to complete necessary errands independently.

  • In addition, the popularity of 'chip tuning' diesel engines to improve their power also risks wiping out the benefits of lower emissions from diesel fuel, and seems to boost PM emissions by a factor of three. Furthermore, says the report, even without factoring in non-tested equipment like air conditioning, CO2 emissions from transport have gone up about 20% over the past decade, as growth outstrips clean technology innovations. An agreement from car manufacturers to cut CO2 to 140g/km by 2008, though likely to be met, will not be enough to have a significant impact on emissions.

  • Although the statutory top marginal tax rate was over 90% in the 1950s, the average tax rate for the highest income taxpayers was much lower.
