An analysis of the basic needs approach in its application to regional economic development with specific reference to Ciske

- Description: In Chapter 7, it was argued that improved satisfaction of basic needs could in principle lead to increased labour productivity and, via a comulative process, to increased output and income levels. Higher incomes could in turn mean further improved satisfaction of basic needs, greater labour productivity and even greater output and income levels. Thus the satisfaction of basic needs could be seen as a means towards the end of improved living standards and the reduction of poverty, and hence an instrument of development policy. From the analysis of basic needs in Ciskei, it is apparent that government expenditure has been such that the "core" basic needs have evidently been catered for, at least to some extent, for some time. Yet, there has been nothing like a concerted strategy, and expenditure on basic needs was the result of ad hoc measures, rather than a conscious strategy or development policy as such. Basic needs were therefore seen simply as ends in themselves, rather than as means to the end of self-sustained economic development. In the case of Ciskei, more information about the satisfaction of basic needs, especially health, and water supply and sanitation, is required at the present stage. Such information should not only be seen in quantitative terms (as "inputs"), but also be evaluated qualitatively (as "outputs"). In other words, basic needs should be viewed functionally as thresholds to the goal of self-sustained economic development. This applies particularly to educatfon, where the total supply may be misleading, more significant measures being quality, access and actual consumption. Data for health, and water supply and sanitation, are not readily available, and again should reflect access and usage as well as availability. Nutritional data should not only reveal the extent and nature of poor nutrition (malnutrition) but also its causes, such as, inadequate expenditure on food on account of low income levels, or inappropriate nutritional patterns of consumption. Data on shelter should take into account the appropriateness of standards and types of shelter, rather than simply the number of houses as such. At the same time, the extent to which basic needs are complementary should be investigated; e.g. the effect the improved satisfaction of education would have on shelter, shelter on health, etc. The stronger such complementarities, the lower total government expenditure on basic needs would have to be. Similarly, if expenditure on basic needs is inappropriate or ill-directed, a revision of standards and redirection of resources may be necessary. In the case of Ciskei, it may well be that total expenditure on basic needs may not be inadequate as such at the present stage, but rather that co-ordination of existing expenditure is required to yield a purposive development policy. A powerful case for the suitability of a Basic Needs strategy for Ciskei may be suggested by the intermediate nature of economic development within its borders. To the extent that some basic needs are already satisfied, at least to some degree and some more than others, certain preconditions for economic development can be said to already exist. Yet it cannot be claimed that Ciskei has reached the "take-off" stage into self-sustained economic growth in the Rostovian sense. Nevertheless, a deliberately co-ordinated Basic Needs strategy may well move Ciskei away from the danger of slipping back into the so-called "Low-Level Equilibrium Trap." In other words, a more scientifically designed, co-ordinated and deliberately applied strategy, whereby basic needs become the means towards self-sustained economic growth, should at least be able to establish the "preconditions for take-off" necessary for sustained economic development.

- Description: From Introduction: As the headmaster of a large co-educational High School in East London, I have to counsel Standard 7 pupils at the end of each year with regard to their subject choices for the Senior Secondary phase. In consultation with the teacher-psychologists and the Standard 7 teachers, one has to make decisions with regard to subjects which could have far-reaching effects on the pupil. Year after year the greatest discussion and most difficult decisions concern whether or not to continue with mathematics. At the end of the Standard 7 year, the pupil is faced with a choice of subjects, one of which is usually mathematics. Depending on the school, this choice is often wide and the average Standard 7 pupil can, in spite of careful counselling and advice, still be bewildered and confused. One of the best methods of objectively predicting pupil performance is through the use of various standardised tests. Although some norm-based tests exist, very few schools apply these tests to help predict mathematics performance in the Senior Secondary Course. To aid the pupil in deciding whether or not mathematics should be taken in Standards 8, 9 and 10 it would be extremely useful if there were some guide or predictor on which this decision could be based, as it is generally accepted amongst teachers that mathematics can be a stumbling block in the Cape Senior Certificate, particularly by the weaker candidate. If it could be shown that the Standard 7 year-end mathematics mark could be used to help predict whether :- •the pupil would be likely to pass or fail mathematics in the Cape Senior Certificate; •what symbol the pupil would obtain; a decision as to whether or not he should continue with the subject could be made at this stage, and, depending on his Standard 7 mark, what the likely consequences of this decision would be. In the United Kingdom in particular, the use of A-level examination results have been used as predictors in subsequent educational courses and this has been the subject of fairly extensive research during the 1970's. The extent to which O-level examination results are predictive of A-level achievement has, however, received very little attention. The situation in South Africa is very similar and very little, if any, work has been done in assessing the effectiveness of using school marks in the lower standards of high school to predict marks in the upper standards. It is difficult to suggest a reason for this as such work would be of inestimable value in providing information for use in the counselling and selection of subjects for pupils embarking on the Senior Secondary Course.

- Description: From Introduction: The reIationship between technology and art today is a logical extension of a collaborative tradition with ancient roots. The artist has always been a principal perpetrator of technological innovation. He, through the natural progression of technical means, has virtually evolved each new art form. There are many examples such as the 'lost wax' casting process, Jan Van Eycks oil paint innovations, Senefelders 'chemical printing' and Niecephore Niepce's first eight hour photographic exposures. Even woodblocks were in their time an innovation. All art uses technology of a kind and artists who prefer to remain aloof from it are in fact merely using technologies absorbed in older traditional media further back in the history of art. It is the flexibility of art to adapt to changing conditions of the world today which has spurred change and brought about a new dynamism in the graphic arts. The present intensity of interest in the print can be directly attributed to the advancement of technology and communication in this century. A whole new field of materials, methods and techniques are now available to the venturesome graphic artist and printmaker. Along with the contemporary technology dedication to expression leads naturally to innovation in aesthetics.

Aspects of the ecology of the shrimp Palaemon pacificus (Stimpson) (Decapoda,Palaemonidae) in the Bushmans river estuary

- Description: The recruitment of Palaemon pacificus to the Bushmans River estuary was studied over a 12 month period. The dynamics of a population of shrimps in a small, tidal channel in the lower reaches of the estuary was investigated over a similar time span. Temperature and salinity tolerances of various stages and sizes of shrimps were compared in controlled experiments and are discussed in the light of the distribution and general ecology of the shrimp. Stage 6 zoeae and post-larvae entered the estuary on nocturnal flood tides throughout the year with peak recruitment occurring in March/April. The population of shrimps in the study site was predominantly juvenile for most of the year, with peak sub-adult numbers occurring in midsummer. The sex ratio was female-biased throughout the year except for short bursts of male predominance in February and April. Average growth rate was 0,043 mm carapace length per day. Maximum residence time in the study site was estimated to be four months and in the estuary at least six months. Flooding of the estuary resulted in a considerable reduction in juvenile numbers in the study site and some loss of sub-adults. Shrimps tolerated a temperature range of 4,3 to 30,9⁰C for 144 hours. Their long term tolerance range is probably narrower (10 to 28⁰C) because of the effects of temperature related factors such as starvation and disease. Their distribution in South Africa (Olifants River to Kosi Bay ) is consistent with this tolerance range. Sub-adults tolerated salinities of 1 to 79 ‰ and post-larvae 2 to 60 ‰ at 15⁰C for 144 hours. Low moulting success (low and high salinities ) and starvation (high salinities) would probably reduce these tolerance ranges to 2 to 56 ‰ (sub-adults) and 4 to 56 ‰ (post-larvae). Higher and lower temperatures (10 and 20⁰C) reduced the tolerance of post-larvae to low salinities, but sub-adults were only affected at 30⁰C. Stages 4 and 5 and stage 6 zoeae were intolerant of salinities below 14 ‰. The development of salinity tolerance with age is consistent with the retention of a marine breeding phase. It also explains the high loss of juveniles from the study site following the flood. It is postulated that recovery of the population after a flood would be fairly rapid except in extreme cases when estuarine vegetation is severely affected.

Low moulting success (low and high salinities ) and starvation (high salinities) would probably reduce these tolerance ranges to 2 to 56 ‰ (sub-adults) and 4 to 56 ‰ (post-larvae). Higher and lower temperatures (10 and 20⁰C) reduced the tolerance of post-larvae to low salinities, but sub-adults were only affected at 30⁰C. Stages 4 and 5 and stage 6 zoeae were intolerant of salinities below 14 ‰. The development of salinity tolerance with age is consistent with the retention of a marine breeding phase. It also explains the high loss of juveniles from the study site following the flood. It is postulated that recovery of the population after a flood would be fairly rapid except in extreme cases when estuarine vegetation is severely affected.

- Description: (From the introduction) Since the introduction of topical corticosteroid formulations, their use has become widespread, being prescribed for a large variety of dermatological conditions. This widespread use has created a need for a reliable method of assessing the various dosage forms of these compounds. Clinical trials are laborious, costly and difficult to mount as well as being impractical for the screening of large numbers of drugs. Patients suffering from dermatological complaints are not ideal subjects for the testing of topical corticosteroid preparations as it is difficult to obtain standardized lesions which are necessary for the comparison of results between patients (Baker and Sattar, 1968). For these reasons a number of methods have been developed for the screening of novel corticosteroids and testing of topical corticosteroid formulations.

Biopharmaceutics of phenylpropanolamine

- Description: Phenylpropanolamine (PPA), a sympathomimetic amine, has been widely used over the past 40 years as a decongestant and, in much larger dosages, as an appetite suppressant. Considerable interest has recently been shown in this drug due to its increasing popularity as an over-the-counter anorectic agent. Much controversy exists concerning the unfavourable side-effects of PPA resulting from the higher doses required for appetite suppression and the potential of this drug for abuse. A literature search revealed a paucity of information concerning the determination of PPA in biological fluids and, most noticeably, on the pharmacokinetics of this drug. An original method for determining PPA in serum and urine using high performance liquid chromatography (HPLC) which has increased sensitivity over other published HPLC methods is presented here. The simplicity of the extraction from biological fluids and subsequent determination by HPLC, enables concentrations of PPA to be monitored after a single dose of the drug. This method is therefore readily applicable to bioavailability and pharmacokinetic studies. The dissolution profiles of 4 sustained-release formulations of PPA were determined in a modified USP rotating paddle apparatus and the samples analysed using HPLC. A mathematical equation was applied to these data which are expressed in terms of dissolution parameters. Oral test dosage forms and solutions of PPA were investigated in bioavailability trials using the developed HPLC method to analyse the urine and serum samples. Linear one body compartment kinetics were assumed and the WagnerNelson method used to transform in vivo serum data to absorption plots which were then fitted to the well known Weibull equation. In order to more appropriately characterize the kinetic processes of absorption, distribution and elimination, a more complex model was utilized which involved numerical integration of a series of differential equations. The data were fitted to these models using nonlinear regression techniques. The pharmacokinetics of PPA are shown to exhibit some evidence of nonlinearity. The absorption of the drug appears to be di scontinuous and PPA seems to favour a two body compartment model.
