- Description: The South African demersal longline experiment is assessed with emphasis on the target species, kingklip Genypterus capensis. The hypothesis that kingklip on the South African coast comprise a unit stock is tested. Recommendations for the management of the fishery are made. Longlining was found to be commercially viable. Techniques have been developed to target on either kingklip or the Cape hakes, Herluccius capensis and H. paradoxus. Longline fishermen exploit the kingklip spawner stock from August to No v ember by taking advantage of prespawning aggregations on the South-East Coast . Effort switches to the West Coast in late summer and early winter where kingklip are less abundant and a larger proportion of hake is caught. Catch rates of kingklip on the South Coast have declined sharply and the resource there has been exploited at a rate greater than that required to retain 50% of the unexploited biomass . There is a 17,6% probability that the spawner biomass on the South Coast has already been depleted below its pristine level. On the West Coast the catch rates of kingklip are lower than on the South Coast and have not changed significantly, although within the 95% confidence limits there is a possibility that the resource there has also been depleted below 50% of its pristine level. Genypterus capensis on the South African coast comprise a unit stock. Comparison of kingklip morphology using multivariate and discriminant function analysis and of otolith morphology using univariate statistics shows that there are no significant differences between the fish on the West and South Coasts. They are a slow growing species and were aged up to 25 years. Kingklip on the West Coast are smaller and have a lower L~ than those on the South Coast, but this is not a characteristic of discrete stocks. Kingklip on the South Coast mature earlier than those on the West Coast and aggregate to spawn on the South - East Coast in spring. There is no obvious spawning period on the West Coast. It is hypothesized that kingklip spawning on the South-East Coast is in response to favourable environmental conditions that enhances the survival of their eggs and larvae. It is recommended that demersal longlining be established as a permanent kingklip-directed fishery but that effort should not be allowed to increase. The West and South Coasts should be managed .separately. A TAC of 5 OOOt for kingklip should be introduced for 1989 of which 2 OOOt should be allocated to the West Coast and 3 OOOt to the South Coast . A closed season for kingklip from 1 August to 30 September on the South-East Coast is recommended. Hake-directed longlining should not be allowed as its effect on the hake spawner stocks are unknown and could be a potential threat to the stability of the demersal trawl fishery.

- Description: Six years as a sub-examiner of both literature and written work made me aware of a personal dissatisfaction with the system of examining. This research examines in detail the use of the contextual question in examining Shakespeare's plays. The main concern has been to try to deduce what constitutes a good set of contextual questions. This area appears to have attracted little detailed research. However, there is much general writing on the teaching of literature. There is no major conclusion in the dissertation but rather a series of conclusions related to the concept of the contextual question. These are summarised towards the end of chapter three. Some general recommendations appear at the end of chapter three as a sub-heading. The findings of this investigation indicate a need for further research into the system of examining literature in the Cape. It is hoped that teachers and examiners reading this dissertation will be able to use the findings to provide a possible framework for the setting of sound contextual questions

- Description: This study attempts to explore, theoretically and empirically, the experience of being black in a predominantly white university. It is more specifically concerned with perceived interaction between members of different cultural and ethnic groups, namely, between black and white. Using the existential-phenomenological method the experience of seven subjects, both male and female, were explicated. This explication revealed that black students become aware of their "difference" during interaction with members of the dominant white group. The black students perceive the behaviour of the white-dominant group to be racist and this creates a great deal of latent hostility, anger, and resentment. It is suggested that a programme be developed to diffuse the conflict situation during intergroup interaction at university.

- Description: The novel as an art form provides writers with the opportunity of exercising their imaginative power to create a 'speaking picture' of life. Whatever form that picture may take, it is vital that it should offer relevance to real life. The literature teacher's earnest intention, therefore, should be to encourage an appreciation of literary novels among adolescent pupils in order to enrich the quality of their living and to sharpen their awareness of the human condition. Teaching adolescents to discern the essential differences between the novel of quality and the novel which exists purely to provide wish-fulfilment and sensual titillation is the aim of this dissertation. Thus a structural analysis of the literary novel is presented, asserting that certain aspects of the novel should be identified and appreciated by the developing reader. Three novels which have recently been prescribed by the Cape Education Department for pupils in standards 9 or 10 are briefly examined in order to test the itensity of their illusion of reality in conjuction with the literary skills of their creators. These novels are Pride and Prejudice (Jane Austen), Wuthering Heights (Emily Brontë) and Tess of the d'Urbervilles (Thomas Hardy). Each has been viewed from a different angle, but each reveals its right to be evaluated as great literature. In order to develop literary appreciation among teenage readers, and to convince them of the delights and insights to be gained, it is proposed that comparison of the 'literary' with the 'unliterary' novel should promote discernment and sound judgement. Popular romance fiction, as published by Mills & Boon, is therefore investigated. These stories enjoy immense popularity, particularly among teenage girls. Far from promoting the illusion that life has been faithfully represented, these novels are shown to reveal a world manipulated to suit both the author and the reader: life as it might have been rather than as it is. A sample of adolescent responses to this type of comparative reading is provided in the last chapter. These responses reveal that the pupils' critical faculties were engaged and literary appreciation was evident

- Description: The need for developing a dry feed which satisfied the nutrient requirements of Oreochromis mossambicus fry was identified. The spawning and grading techniques which resulted in a higher fecundity and ensured uniformity within and between samples of fry are discussed. Preparation techniques were developed which met the physical requirements of fry feeds. An analysis of the flesh and yolk sac fry for amino acid composition was undertaken. The initial test diet was based on these results, as well as on the natural feeding ecology of the species. Feeding trials were undertaken and growth responses monitored to determine the optimum levels of the various dietary components. A feed was developed which gave superior growth to that obtained with natural food organisms. This feed consisted of Torula yeast (47%), Weider Super Protein (44.39%), Vitamin supplement (0.45% - multivitamin), additional vitamin C supplement (0.16%), Spirulina (5%), and methionine supplement (3%). An optimum particle size range for O. mossambicus fry (between 5 & 25mm) was established at 125-200um. The fry should be fed the following feed ratios depending on age: 30.4% body weight/day up to day 5, 30.6% body weight/day up to day 10 and 25.1% body weight/day up to day 15. An optimum feeding frequency of 8/10hr day was recommended. A feed conversion ratio of 1.24:1 and a protein efficiency ratio of 0.682:1 was obtained. Digestable energy of the feed was determined at 16.1 kj/g feed. The established dry feed is suitable for use in commercial hatcheries, and as a formulation for further research on the intensive rearing of O. mossambicus fry.

- Description: Many students find that their greatest academic step is that from high school to college or university, and that it involves a transition affecting almost all aspects of their lives. In order to offer assistance to students experiencing transitional and other personal problems, Student Counselling Services have been established and are operature at most tertiary institutions in Southern Africa. Currently no such service exists on the campus of the Cape College of Education, Fort Beaufort. This exploratory study attempts to determine whether there is a need for such a service and further, to establish factors which might encourage or discourage students from using such a service. An open-ended questionnaire was administered to 178 students at the College in order to gain insight into their ideas and feelings and what they perceive their needs to be. Through an explication of the student protocols, several major themes emerged and are discussed in detail. The research findings suggest a need for the establishment of a counselling service, and shed some light on factors which need be considered should such a service be offered. The methodological approach is discussed as well as recommendations for improvements.

- Description: This study involves an investigatioh into the nature and effectiveness of the pre-service training, where provided, of secondary school Mathematics teachers at the 11 colleges of education administered by the House of Representatives in the Republic of South Africa. The purpose of this study is to determine whether the HDE (Secondary) course offered at some of the aforementioned colleges of education is justified, In spite of the fact that it contravenes the requirements of the Education Act, No. 73 of 1969. Three different questionnaires were designed and during 1986 were sent to heads of Mathematics departments at the aforementioned colleges of education , to Mathematics teacher educators at these colleges and to beginning secondary school Mathematics teachers, teaching at schools administered by the House of Representatives in the Eastern Cape and Natal. The findings of this study show that the secondary course for Mathematics teachers is only offered at 5 of the 11 colleges of education and only a small percentage of students take this course. During 1986 most of the Mathematics teacher educators at the colleges of education were not suitably qualified. The study also shows that the Mathematics curriculum for the training of secondary school teachers is inadequate and a revision thereof is thus recommended. An obvious conclusion drawn from the findings is that the training of secondary school Mathematics teachers at these colleges of education is still in an early stage of development. One of the main recommendations of this study is that the training of secondary school Mathematics teachers at colleges of education administered by the House of Representatives should be terminated , in view of its ineffectiveness and In accordance with Education Act , No . 73 of 1969. On the other hand, in case this is not possible, suggestions are also made for the improvement of the pre-service training of secondary school mathematics teachers at these colleges of education.

The criteria adopted in this work for a successful CPNF include: 1. the tensile strength of the fabrics 2. a well-defined pattern 3. absorbency and wicking The properties selected for investigation were 1. the cotton fibre surface (using SEM and DSC analyses) 2. the degree of degradation of the cotton fibre as a result of the CPNF process (using cellulose fluidity measurements) 3. the non-cellulosic content of the fibre (using IR, DSC, and Chemical analyses) 4. fibre friction 5. absorbency and wicking 6. tensile properties Analysis of the results indicates clearly what the fundamental properties of the cotton fibre must be for a successful cotton CPNF to be manufactured. The conclusions also indicate the necessary properties a man-made fibre must have to produce a successful CPNF.

This investigation set out to discover the guidance needs of pupils specifically in the social/personality area, and further, to state these needs in such a way as to allow the logical development of guidance programmes. Group and individual interviews were conducted using a sample of 72 high school pupils, selected from standards six to eight. The results show clearly the areas in which the pupils perceive their needs to lie. It is also apparent that further research in this area is strongly indicated.

- Description: The focus of this research was the reappraisal in physiological and psychophysical terms of current equivocal theories regarding the onset, course and termination of apneic bradycardia. Sixteen healthy male subjects participated in four separate testing sessions . Maximal oxygen consumption (VO₂ max) was measured on land and underwater using an identical direct, continuous progressive cycle ergometer test. On each of two other occasions subjects exercised in either environment at 50, 70 and 90% of the appropriate VO₂ max, during which time heart rate was continuously recorded. An initial apneic bout at each exercise intensity was followed by performance of the same workload without apnea for an equivalent period of time. Ratings of perceived exertion (RPE) were also monitored. While apneic bradycardia occurred at each exercise intensity studied underwater, it was apparent only at 50% VO₂ max on land. With the exception of between 50 and 90% VO₂ max on land, the mean apneic heart rates did not differ with varying exercise intensity (p<0.05); nor did the lowest heart rate recorded, although this was lower underwater than on land. Apart from 70% VO₂ max on land, apneic heart rates were lower than the equivalent values measured during exercise without apnea. Land and underwater heart rates during apneic and non-apneic conditions did not differ until 90% VO₂ max. The effects of increasing exercise intensity upon the onset of bradycardia were evident in that it occurred earlier at 50% VO₂ max underwater than at the heavier workloads, and only at 50% VO₂ max on land. The mean breath-hold duration did not differ between the land and underwater environments, nor was it affected by increasing exercise intensity. The order in which breath-holds was performed did not alter the length of apnea. Land and underwater RPE did not differ and increased with increasing exercise intensity in both environments. During apneic exercise RPE was greater than the equivalent exercise without apnea. Twelve of the original 16 subjects were divided equally into two groups on the basis of vital capacity expressed relative to body surface area. Vital capacity was measured during the first laboratory session. Neither the mean heart rate response to apneic exercise at 50% V0₂ max in both environments, nor the lowest heart rates recorded differed between groups, prompting the conclusion that lung volume did not affect apneic bradycardia. Despite a longer breath-hold duration for Group A (large relative lung volume) than Group B (small relative lung volume), the onset point of bradycardia was the same for either group when expressed relative to total breath-hold duration

- Description: If I am aware of my own mental states by introspection (a) How can I know that other people have minds? and (b) How can I know what their mental states are? These are two of the questions with which I will be concerned in this dissertation. I discuss five different attempts to deal with them. (i) The claim that we can know that other people have minds by an argument from analogy. I show a number of serious flaws in Russell's and other versions of this argument. (ii) Malcolm's thesis that the criteria by which we apply mental terms to others are just different from the criteria one applies in one's own case. I argue that Halcolm's accounts of both first- and third-person criteria are not adequate. (iii) I consider Strawson claim that 'persons' is a primitive concept and that behavioural criteria are "logically adequate" for determining the correctness of statements about the mental states of others. I argue that both of his key concepts are underanalysed. (iv) A quite different attempt to answer our questions (a) and (b) is given by the empirical realist who argues that knowledge claims about other minds are best understood as hypotheses in a wider psycho-physical theory. I show that the major fault in Putnam's version of empirical realism is that he overlooks the subjective character of (iii) our mental states. (v) Finally I consider the claim, due to Nagel, that a conception of mental states is possible which incorporates both subjective and objective aspects of the phenonemon. I speculate that with a great deal of development this approach might hold the answer to our questions.

- Description: An investigation into the quality of surface water and ground water was conducted during 1988 in the 38,8 km² Hout Bay River catchment near Cape Town. The main objective of the study was to determine those areas and activities which constitute a pollution source and to ascertain the relative proportion which each contributes to the pollution problem and health risk of the surf zone of the beach at Hout Ba . The objective was achieved by monitoring the chemical and microbiological attributes of the Hout Bay River, its tributaries and stormdrains in wet and dry conditions on a routine basis and during storm events. Hout Bay is a rapidly developing residential area in which sewage disposal occurs by means of septic tank soakaway systems. Ground water quality was monitored to investigate the contribution to contamination by septic tank effluent. Results showed that stormdrain effluent in dry and wet conditions and surface runoff during rainfall were the main vectors of pollution. Although the pollution concentration was high during dry conditions the greatest pollution discharge to the surf zone of Hout Bay occurred during storm events. In view of the proposed residential development it is imperative that pollution control measures be undertaken so as to secure the future recreational and aesthetic value of Hout Bay

- Description: Emphasis in the study is on the prevalence of poverty especially in the so called third world developing countries. Poverty as a social problem is caused by a number of factors, viz: Over population, unemployment, illiteracy, etc. In the case of the study the focus is the rapid population growth or "population explosion" as it is commonly known. Family planning is sen as important, but not the only strategy in combatting the interrelated problem of population growth and development. The relevance and importance of social workers, as members of a multidisciplinary team in the delivery of family planning programmes is emphasised. There is evidence in the study to support the observation that Black African people in particular are reluctant to use family planning methods. Based on this evidence, the basic assumption arrived at is that there is a general unfavourable attitude to family planning in the Taung area. The research design used is exploratory-descriptive. Of the 75 areas in the district, 10 areas were included In the investigation. A stratified random sample was used, with a sample size of 200 respondents. The interview schedule was used to collect data. It was structured and consisted primarily of close-ended questions, and was analysed using the Biomedical Data Programme (B.M.D.P.). The problem is formulated from literature concerned with population growth in the Republic of South Africa as well as Bophuthatswana. The following sub-problems were described: illegitimacy; health and economic problems associated with large families; abortion; malnutrition and malnourishment; and the absence of services of the National Family Planning Programme In the Taung area. Compatibility between social work and family planning is a central concern, with community development as a significant method of intervention. The three important concepts in the study were broadly defined, viz: Overpopulation, family planning and attitude. It was established that: -the use of family planning follows rather than precedes the process of modernisation and rising economic standards; -no family planning programme can be practised universally - because of factors such as culture, need and habit. Attitudinal change is considered based on the basic assumption arrived at. Little has been done on the subject of family planning in south Africa. With regard to the role of social work in family planning, there have been impediments along the following lines: lack of firm tradition; emphasis on treatment rather than on preventive work; a view of family planning asa health measure and to be offered solely in the medical and health services. To be active in this field social workers need formal education and training. Taung: - the area of study is predominantly rural with almost all characteristics of rural areas, those of: Irregular transport services to and from remote areas; corrugated roads; primitive sanitary conditions; poor communication system; absence of electricity in villages; illiteracy and unemployment. On the other hand, development is evident especially in the health, education and welfare fields. The central findings in the study are those arising from resistances to family planning usage - politically; culturally; morally and psychologically. The general conclusions are: The high rate of unemployment is present in the sample and there is financial dependence on partners (men); the importance of social workers in family planning is emphasised; there is a desire to have large numbers of children (children feature prominently in the area and are regarded as an asset in various ways); and lastly, improved education does lead to an increase in motivation to adopt family planning practices. Against the highlighted findings, recommendations were made, viz that: Community development be used as a strategy for change; social workers be involved as team members in family planning - in policy formulation and planning of population programmes at various levels, using different methods of intervention; paramedical aides beused - because of inter alia shortage of qualified manpower and lastly formal education and training to be granted to prospective change agents in family planning delivery programmes. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

We find that in a T₂ space (in the sense that no fuzzy net converges to two fuzzy points with different supports) all these notions are equivalent for the whole space. Furthermore, for N-compactness and f-compactness (being the only notions that are defined for an arbitrary fuzzy subset) we have equivalence under a stronger condition, namely, a T₂ space in the sense that every prime prefilter has an adherence that is non-zero in at most one point

- Description: Mortality has always been a popular theme in literature. By means of a semiological and narratological approach, it has been endeavoured in this study to prove that transience comprises a complex code constituted by a whole series of codes. In each of the chosen volumes one specific short story is analysed and all the codes related to transience are defined and described. Then these codes are discussed within the context of the volume as a whole. The following codes have been identified and analysed: death and death related codes, decay, distress, frustration, emptiness, loneliness observe, look and see, reproduction, the code of ageing, youth/ageing, lost love, time. The following texts of Aucamp have been used as the object of study: Die Hartseerwals, Spitsuur and 'n Bruidsbed vir Tant Nonnie. The reason these texts were selected, is twofold: They represent the early works of the author. The continuity is essential for making meaningful deductions. The final conclusions are: Man's bond with an environment which is characterised by continual change, influences his existence and makes his life a tentative experience. Transience involves more than merely ageing, obsolescence and death. Transience is a complex experience, related to the physical and mental in man. Besides ageing, sexuality contributes to man's downfall. Loneliness, isolation and frustration determine his actions and stress his experience of transience. The result is a painful experience of life.

- Description: High drop-out rates in the sub-standards in developing countries prompted the researcher to investigate preschool education in first and third world countries, and attend to the related problem of school readiness. The rapidly expanding Educare preschool project in the rural area ot Keiskammahoek in Ciskei was investigated as an example ot community-based low-cost preschool education. A final sample of 41 children who had attended Educare Centres were matched to a control group on age, sex, primary school (where possible), and breadwinner's occupation. The Abbreviated Aptitude Test for School Beginners (standardised on Xhosa-speaking school beginners) was used to test tor significant differences between the two groups six to seven weeks atter school entry. A t-test was used on raw scores and chi-squared tests on staves. No signiticant difference was found between the means of the experimental and control groups. On a subjective rating scale for general-linguistic development and socio-emotional adjustment, no significant difference between means of the experimental and control groups was found. The experimental group's tailure to perform better than the control group, could be ascribed to various reasons, amongst others, the possible shortcoming that the pairs were not matched on intelligence, severe lack ot equipment in Educare Centres, large numbers of children in the majority of groups, uniform programmes for a wide age range, irregular attendance ot children, the low level of training of supervisors and poor home conditions. Scholastic abilities of school beginners in the Keiskammahoek District, as tested, were poor. Results deviated grossly from standardised norms. The expected percentage for the combined categories Very Weak and Weak is, tor instance, 31%; in this investigation, however, 73% of the testees fell in these two classes. Chronologically older children generally performed better. A highly significant difference existed between testees under six years and those over six years. This investigation indicated the need for better organised preschool education in rural areas in Ciskei. proposals with substantial financial implications are: Better training of para-professional staff by qualified staff. Training of qualified staff to provide expertise in preschool education in Ciskei. Provision of sufficient educational materials by Government subsidies and private sponsors. Institution of bridge classes by the Ciskei Department of Education to promote school readiness. Suggestions without financial implications include: An investigation of regulations regarding entrance age for basic education. Only in exceptional cases should children under six be admitted. Daily programmes in Educare Centres geared towards learning readiness without becoming academic. An age limit of three years for admittance to Educare Centres. Very young children should be catered for separately. Liaison between Sub A teachers and Educare staff. , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: This study investigated the effects of incremented loads greater than maximal acceptable loads on selected locomotor kinematic and psychophysical variables for four different hand-held load-carriage methods. Ten male and ten female subjects, between the ages of 18 and 30, participated in four experimental sessions. Data collection involved obtaining selected anthropometric, strength, maximal load and preferred load, gait kinematic, and psychophysical values. The anthropometric, strength and load capacity variables enabled absolute and morphology normalised sex-based comparisons to be made. The kinematic and psychophysical parameters were used to quantify any changes from two sets of baseline values,"unloaded" and "maximal acceptable load" values, when loads were increased and carrying methods changed. Statistical analysis revealed that males were taller, heavier and stronger than females (p<0.05). Males chose significantly greater maximal acceptable loads and absolute maximal loads than females when expressed in their absolute or relative terms. Preferred walking speeds were not significantly different for unloaded or loaded conditions, although males walked significantly faster in absolute terms (but not in relative terms) than females. Different load carrying methods and incremented loads brought. about significant changes to several of the kinematic parameters investigated. Finally, ratings of perceived exertion, as well as the number of exertion sites, were seen to increase significantly as load increased. These values were not, however, significantly affected by differences in load carriage method.

- Description: This study investigated the influence of human morphology upon selected physiological, biomechanical and psychological responses to horizontal locomotion. In so doing, it was possible to evaluate the effectiveness with which morphology-normalised speeds of walking and running reduced the between-subject variability that is inherent in human locomotor responses. Twenty caucasian males were divided into two groups on the basis of stature - ten subjects in each of a "short" category (<170cm) and a "tall" category (>185cm). All subjects were habituated to treadmill locomotion prior to exposure to three walking treatments (0.83, 1.39 and 1.94m.s⁻¹) and three running treatments (2.50, 3.06 and 3.61m.s⁻¹). During each of these five-minute locomotor conditions, energetic (V02), kinematic (cadence and stride length) and psychophysical (central and local RPE) data were captured. From these data, lines of best fit were calculated for each subject, allowing for a prediction of the abovementioned locomotor variables from known absolute rates of progression. Using suitable regression equations, subject responses to morphology-normalised speeds of walking and running were effectively extrapolated. When the rate of progression was expressed in absolute terms (m.s⁻¹), significant differences (P <0.05) were found between the stature-related groups with respect to both energetic and kinematic locomotor responses. Such differences were successfully eliminated when use was made of locomotor speeds relativised on the basis of morphology. This study concludes that the use of appropriately prescribed morphology-normalised rates of progression are effective in reducing the variability in locomotor responses between subjects differing significantly in stature.

- Description: This study deals with the problems of external examining, the inflexible demands of which dominate and dictate to literature teaching in South African schools today. The aims of teaching literature are discussed, and it is suggested that the negative attitudes among pupils resulting from the present examining system defeat many of these aims. The opportunities for the enjoyment of literature are minimised by the process of preparation for external examinations. Creative teaching methods are abandoned in favour of coaching for specific types of questions, which are determined and limited by the practical constraints of a mass external examination. In catering to the demands for admininstrative reliability and efficiency, the educational validity and efficiency of the examinations are sacrificed. In Britain the Newbolt and Bullock Reports, among others, have made forceful recommendations for alternative approaches to external examining. Subsequently, much experimentation with internal examining, course-work and open-book examining has followed, aspects of which are discussed in this study. There has been limited experimentation in these areas in South Africa. The TED conducted a successful internal examining experiment in English literature, the results of which are considered in this thesis. The national English Olympiad open-book examination is a further example of the success of an alternative approach. By contrast, a comparison of examination papers set by the JMB and CED over the last ten years, shows clearly that the stated syllabus aims of teaching literature and the aims of examining the subject were wholly incompatible. Recommendations are made for the adoption of alternative examining strategies in order to address the shortcomings identified

- Description: The purpose of this study is to identify, observe and record the attitudes and use to of contraceptives by black males in Umtata and to investigate the effect of education, urbanisation and age on fertility control. Data was gathered from a sample of adult males who were past the school going age and were employed or working in Umtata and its surburbs, which are Ngangelizwe, Ikwezi, Southernwood, Northcrest, Norwood, Ncambedlana, Nduli Crescent, Fortgale and Hill Crest. Information was also gathered from Nursing officers in charge of family planning service centres in the areas mentioned above. Findings reveal that, although black urbanised educated males in Umtata seem to have accepted the use of contraceptives by themselves and their sexual partners, their patterns of behaviour in relation to fertility control and the value of children to families remains traditional. This contributes to the relatively high fertility rate in the country. Children are an investment for old age. They are also regarded as a security factor against divorce. It is the duty of legally married couples to raise a family with children who will continue to bear the family name. It appears that men are either suspicious of modern contraception if not totally opposed to it. Many still prefer the use of natural methods of contraception. There is thus need for social workers and health planners to recognise and educate males on the use and benefits of modern contraceptives to limit the number of children borne and control periods when they would like to have children. This study will be of value to social welfare services and to family planning nurses who are in direct contact with clients in hospitals and clinics, in their family planning campaigns, when they motivate couples and individuals on the importance of family planning, and also in mother-and-child health services. Educationists, sociologists, psychologists and persons in other fields of study will also benefit from information attained in this survey.
