- Description: The quality of the Bender-Gestalt performance of 22, normal, white South African male adolescents and 22, normal, Xhosa male adolescents, aged between 17 and 22 years, was investigated. The Pascal-Suttell scoring system was used. The mean score of the white adolescents was significantly below that of the Xhosa adolescents. It was found that while the mean score of the Xhosa adolescents was within one standard deviation of Pascal and Suttell's normative 'high school' mean, the mean score of the white adolescents was below that of the normative mean and not within one standard deviation of the mean. The results lend support to the findings that Bender performance is related to cultural background. It is suggested that the Pascal-Suttell tables may be in need of revision. The advisability of standardising tables, which are culture specific, for clinical use· in the Southern African context, is indicated. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: A Period of Transition : A History of Grahamstown 1902-1918 attempts to show that the trends begun in the nineteenth century were confirmed by developments in the first two decades of the twentieth century. In this period, Grahamstown was forced to abandon ideas of economic recovery and political importance, as it adapted to its role in the post-Union dispensation. The city has been firmly grounded in the wider environment, though comparison with towns of similar position and outlook has been impossible because of a lack of source material.4 It is clearly evident that Grahamstown was under pressure from the macrocosm; nonetheless, local initiatives and developments also lent clarity to broader trends. This is particularly clear in the emerging pattern of racial segregation in the City, to cope with the economic and social problems posed by a burgeoning black population. The limited financial resources of a corporation the size of Grahamstown restricted its effectiveness to improve schemes of public works and public health, and further underlined the dependence of the city on the government for assistance. Grahamstown's transition was predominantly one of acceptance of a changed political, social and economic environment.

A phenomenological explication of the male alcoholic's experience of existence with mother and father

- Description: Much is written, especially in psychodynamically oriented literature, about the unduly close dependency relationship male alcoholics have with their mothers. Whilst not disputing this it became apparent to myself when working with them that they also expressed strong attachments to their fathers who were described as absent or punitive. The literature goes on to theorize that a repressed homosexual element is often at work in the male alcoholic. Not much more of substance is said about the father other than he may be absent or punitive - even less is mentioned of the male alcoholic's experience with his father. It appears that this relationship has remained largely unexplored as a result of an uncritical imposition of theory, especially psychodynamic, upon the complex phenomenon of alcoholism. These theories generally posit the mother's influence over all problems in living be they neuroses, psychoses or alcoholism. It is possible that a dialogue exists between mother, father and alcoholic son which is more extensive and complex than that currently described in the literature, with father playing a greater role than previously believed.

- Description: From Introduction: The impact of computer technology has not yet been felt in South African primary schools. Yet it is believed that the effect of microelectronics on society will cause a revolution as significant as the industrial revolution. Whereas the industrial revolution amplified and extended the power of human muscles, the new microcomputer technology will mostly be concerned with amplifying and extending the power of the human mind. In order that the future generation might come to terms with the rapidly changing conditions, it is suggested that children of school age benefit by gaining experience with the new technology. It was against this background of challenge that I began to explore various uses of the new technology. The Cockcroft Committee (1982) investigation considered many aspects of mathematics teaching in primary and secondary schools in England. They gave a clear indication of the place of the microcomputer in mathematics teaching when they made this significant observation, "There can be no doubt that the increasing availability of microcomputers in schools offers considerable opportunity to teachers of mathematics to enhance their existing practice and also to work in ways which have not hitherto been possible." (para. 402). The aspect of 'doing' mathematics 'in ways which have not hitherto been possible' caught my attention. I saw the microcomputer as a powerful tool which would extend the children's range of mathematical experiences through the use of simulations. Seymour Papert (1980) propounds an exciting vision of education for the future which consists of collaboration between computers and children. His philosophy does not allow for computers programming children through drill and practice methods. He envisages the child programming the computer and mastering the powerful technology by using a highly active problem solving method. Besides learning problem solving skills, the aspect most emphasized by Papert (1971, 1972, 1980) is that through building and experimenting with computer programs, a child ought to gain new mathematical insights in the topic under investigation.

- Description: Consider the possibility of the remnants of our present day society being excavated and studied in centuries to come. Imagine the craftsmanship, the art, artifacts and architecture that will then be compared to those of the past centuries. Our entire culture will be labelled by the endless array of rubbish that has become an integral part of our lives. The increasing prevalence of kitsch in the society goes almost unnoticed where it should be causing concern. Few people are aware of its existence, or the permanent aesthetic scars induced by this prevalence. How has this cult of sheer awfulness come about and why has it become prevalent? It is impossible to pursue all the avenues of kitsch - so vast is it but it is the purpose of this study to try and answer some of the questions, in order to make people more aware of what has crept into our society, to help them become more discriminating, and not merely to level criticism at the perpetrators of kitsch.

- 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.

- Description: This thesis continues the Rhodes 2.3 GHz Survey of the Southern Sky. It consists of two parts : a data processing part and an astronomical analysis part. In the data processing part the data for the regions 4HR to 15HR, -80° to -61° and 12HR to 23HR . -27° to -7° are presented in contour map format. A beam pattern of the Hartebeesthoek telescope at 13 cm is constructed from drift scans of the radio source TAU A. This is used to investigate the data filtering techniques applied to the Rhodes Survey. It is proposed that a set of widely spaced scans which have been referred to the South Celestial Pole can provide a single calibrated baselevel for the Rhodes Survey. The observing technique and the necessary reduction programs to create a coarse grid of antenna temperatures of the Southern Sky using these observation are developed. Preliminary results for this technique are presented as a map of the region 18HR to 6HR, 90° to 30° with a 5°x5° resolution. On the astronomical side two studies are undertaken. The region 13HR to 23HR, -61° to -7° is searched for large extended areas of emission. 7 features occurring at intermediate galactic latitudes are found. They are interpreted as follows: one of them is the classical HII region surrounding the star Zeta Ophiuchi (l",b")=(6.7°,22.4°), and the rest are combinations of thermal and nonthermal emission from galactic features. The galactic equator profile for 24°> L > -58° is studied. It is dominated by a plateau of emission for L < -26°. This is interpreted as a combination of thermal and nonthermal radiation emitted by a ring of gas symmetric about the galactic centre with a radius of 4 - 6 kpc.

- Description: From Introduction: Anyone familiar with David Storey's work will find, on reading a brief outline of his life, that much of the inspiration for his novels and plays springs from personal experience. The third son of a coal-miner, he was born in Wakefield on 13 July 1933. He is one of three surviving sons, an older brother having died in childhood. (In Saville and In Celebration the death as a child of a mining family's eldest son has a powerful effect on the parents and some of the remaining brothers.) Although his father wanted his children to reach the middle class through education, Storey has indicated that this ambition was not pursued wholeheartedly.

Design automation of a machine-independent code generator

- Description: As both computer languages and architectures continue to proliferate, there is a continuing need for new compilers. Researchers have attempted to ease the work of producing compilers by developing methods to automate compiler writing. While much work has been done (and considerable success achieved) in writing parsers which can handle a variety of source languages (using mainly table-driven analysis methods), less progress has been made in formalizing the code generation end of the compiler. Nevertheless, some of the more recent publications in code generation stress portability or retargetability of the resulting compiler. A number of code generator synthesisers have been developed, some of which produce code that can be compared in quality with that produced by a conventional code generator. However, because of the complexity of generalizing the mapping from source language to target machine, and the need for efficiency of various kinds, code generator synthesisers are large, complicated programs. Consequently, the person who develops a code generator using one of these tools invariably needs to be a code generation specialist himself. Many compilers follow a pattern of having a front end which generates intermediate code, and a back end which converts intermediate code to machine code. The intermediate code is effectively machine independent, or can be designed that way. With these points in mind, we have set out to write a system of programs which -- 1. will allow the generation of such a back end in a reasonably short time, for a general intermediate code, and for a general machine code, and -- 2. can be used by anyone who has a sound knowledge of the target machine's architecture and associated assembler language, but is not necessarily a specialist compiler writer. The system consists of a series of friendly, interactive programs by means of which the user sets up tables defining the architecture and assembly level instructions for the target machine, and the code templates onto which intermediate codes produced by a parser have been mapped. A general notation has been developed to represent machine instructions using the same format as the target assembler. Thus the code generator writer is able to write code sequences to perform the effects of the intermediate codes, using assembly mnemonics familiar to him. The resultant table-driven code generator simply replaces a sequence of intermediate codes by their respective code templates, relocating them in memory and filling in addresses known only at code-generation time. This thesis describes the use and implementation details of this generalized code generation system. As an example, the implementation of a code generator for a CLANG [23] parser on an 8080 processor is described. The discussion also includes guide-lines on how to implement a loader and associated run-time routines for use in executing the object code. The results of a number of bench-marks have shown, as expected, that code produced by a code generator developed in this manner is larger and slower than that from a special purpose optimizing code generator, but is still several times faster than interpreting the intermediate code. The major benefit to be gained from using this system lies in the shorter development time by a less skilled person. , KMBT_223 , Adobe Acrobat 9.53 Paper Capture Plug-in
