- Description: Population dynamics is a South African secondary school biology syllabus topic which deals specifically with ecology or concepts within the realm of ecology. It is currently taught in a way which largely emphasises the teaching and learning of facts and concepts, often out of any context to which students can relate. While it is important to convey scientific concepts, it is just as important to address social and political issues regarding overpopulation and the environment. This research involved the administration of a questionnaire to Std 10 biology teachers in the Department of Education and Training (DET), which sought to obtain information about various aspects of teachers' teaching of population dynamics. These included their feelings toward the teaching of the specific sections of the population dynamics syllabus, and their knowledge and views of environmental issues and human population expansion. The findings of the research suggest that population dynamics is an important topic for students to learn about. The traditional teacher-centred approach to teaching is used by the teachers in the research sample. The sections considered by the teachers to be most important for learning were also considered the most interesting and the easiest to teach. The majority of the teachers in the research sample recognised that human population growth is a global and local problem and that South Africa cannot sustain its present population growth. The teachers in the sample show a diversity of opinions about sustainable development, and have a limited understanding of the links between population, poverty and consumption. Important information gained from the research will be significant in the development of a teaching and learning module on population dynamics that reflects the aims and purpose of environmental education.

- Description: A clinic survey was undertaken to investigate the nature of psychiatric problems experienced by the primary health care (PHC) patient population in the Bisho-King William's Town area of the Eastern Cape Region. The study took as its point of departure research findings which attest to the high rate of psychiatric distress amongst this population group in different parts of the world and ohservations regarding the form of presentation in terms of physical complaints. Hypotheses posited relationships between psychiatric problems experienced by patients attending PHC clinics in the study area and four types of variables, namely; somatic complaints, socio-demographic characteristics, patterns of health service utilisation and patient satisfaction with health services. Using a quasi-experimental descriptive approach, a two-stage screening procedure sorted the patient sample into three groups on the basis of the degree of psychiatric symptomatology experienced. The triangulation of the results of between-groups analyses with case materials recorded during psychiatric interviewing provided for an ethnographic account of the cultural experience of distress in the study area. The screening process used standard instruments, the Self-Reporting Questionnaire (SRQ) in the first stage and the Present State Examination (PSE) in the second stage. A pilot study was conducted prior to the fieldwork for the main study. Using the SRQ, thirteen psychiatric paticnts and 31 general PHC patients were sampled for the pilot study and 148 PHC patients were sampled for the main study. Using the PSE, 11 and 57 PSE interviews were conducted in the pilot and main studies respectively. Between-groups analyses used chi-square and F-statistics to investigate possible associations with identified patient correlates (P<0.5). These were socio-demographic, utilisation and satisfaction variables, measured by a separate face-valid self-response instrument compiled for the purposes of this study. Psychiatric symptomatology was found to be statistically significantly related to age, marital status and educational level. Further, patients experiencing more psychiatric symptomatology reported significantly more illnesses requiring treatment, longer consultation periods and a greater number of sick bed days. No statistically significant relationships were found between psychiatric symptomatology and number of children, number of failures at school, amount of treatment utilised, number of consultations, or patient satisfaction with services. Descriptive analyses of symptom and syndrome profiles found certain somatic complaints to be particularly prevalent amongst the patient sample. These include headaches and various tension pains, decreased energy levels and digestive problems. Qualitative analysis of interview data found that many somatic and psychiatric problems experienced constitute culturally defined and meaningful experiences, especially 'umbilini' (or nerves), 'ufufunyana' (a possession state), and accusations of witchcraft. Interpretation of complaints from the local traditional healing perspective, revealed a more complex mode of communication between patients and the health delivery system than may be accounted for in terms of a simple biomedical model. The interpretive analysis in the study showed that some forms of presentation incorporating somatic symptoms, such as 'nerves' may he viewed as help seeking behaviour of the socially unempowered. Implications of the results are discussed in relation to the need for improved identification and management of psychiatric distress at PHC level facilitated by a better developed referral network and closer interaction between biomedical and anthropological perspectives.

- Description: This study aimed at investigating the relationship between adolescent parasuicide, depressive illness and associated risk factors. Reports worldwide indicate that suicidal behaviour in this age group has risen 150% over the past 20 years, whilst the rate for suicide in adults and the elderly has remained the same (Deykin et al, 1985; Neiger & Hopkins, 1988; Sudak, Ford & Rushforth, 1984a). In South Africa statistics confirm similar trends with regard to attempted and completed suicide. Statistics reveal that a high local incidence of adolescent suicide attempters are seen at psychiatric units. One pilot study recorded 187 adolescent suicide attempters during a three month period. This study was based on the hypothesis that the incidence of depressive illness in adolescent suicide attempters is higher than is generally accepted and that this condition often goes unrecognised and is misdiagnosed because it manifests differently with acting out behaviour and "masked" symptomatology. A random sample of suicide attempters between the ages of 13 - 25 who presented at C23 (psychiatric emergencies) Groote Schuur Hospital following a suicide attempt were assessed. 100 subjects were seen over a period of three months. The research procedure comprised a comprehensive assessment incorporating a semi-structured interview, self-report and objective rating scales for depression as well as instruments designed to assess the general health of each subject and their level of suicide intent. The depressive inventories used have been validated for use in this age group and were designed to elicit the associated features of adolescent depression. If warranted, a clinical diagnoses was given based on DSM 1V criteria. This diagnosis was substantiated by information from the research instruments which formed part of the assessment process. A high incidence of clinical disorders was diagnosed in the sample (86%). Depressive illness was found to be a significant risk factor for suicidal behaviour with 68% of the subjects suffering from an affective disorder and 21% reporting depressive symptoms. This study shows that the correlation between parasuicide and depressive illness is high enough to suggest that all suicidal behaviour in this age group should be taken seriously as parasuicide in itself is often a reliable indicator of an underlying depressive condition. Additional risk factors for adolescent parasuicide identified in this study correlated well with the findings of similar research studies. Psychiatric co-morbidity, especially substance use (42%) and cluster B personality factors (54%), were high and served to increase an individual's vulnerability to suicide risk. Psychosocial factors such as sexual abuse (28%) and physical abuse (37%) were also identified as high risk factors for adolescent suicidal behaviour. Individuals at risk for depression and suicidal behaviour typically came from broken homes which were disrupted and unsupportive. Family members were frequently abusing alcohol and 67% of the subjects reported the presence of psychiatric illness in the family. The preferred method of suicide attempt was an overdose (90%). These attempts were generally unplanned and impulsive with no disclosure prior to the event. Intent was usually high at the time of the act. It is only through identifying the risk factors specific to the developmental concerns of this age group and acknowledging the role of depressive illness in adolescent suicidal behaviour that effective preventative measures can be devised.

- Description: Besshi-type deposits range in age from early Proterozoic to early Tertiary, of which the largest number are late Proterozoic, early Palaeozoic or Mesozoic in age. No Archaean examples of Besshi-type deposits are known, probably due to insufficient availability of sialic crust for erosion and clastic marine sedimentation before the start of the Proterozoic. All Besshi-type deposits are contained within sequences of clastic sedimentary rock and intercalated basalts in a marine environment. The basalts and amphibolites are principally tholeiitic in composition. Besshi-type deposits characteristically form stratiform 1enses and sheet-like accumulations of semi-massive to massive sulphide. The main ore assemblage consists dominantly of pyrite and/or pyrrhotite with variable amounts of chalcopyrite, sphalerite and trace galena, arsenopyrite, gold and e1ectrum, barite being absent in general. The median Besshi-type deposit (n=75) contains 1.3 million tonnes (Mt) of massive sulphide with a Cu grade running at 1.43%. It is suggested that Besshi-type deposits form by both exhalative and synsedimentary replacement processes when considering geological features and comparisons with modern analogues in the Guaymas Basin, Middle Valley and Escanaba Trough. The currently forming metalliferous sediments in the Red Sea provide for a brine pool model explaining the lack of footwall feeder zones below sheet-like deposits. Where thick sulphide lenses are contained in some Besshi-type deposits, combinations of exhalative precipitation and sub-sea-floor replacement of permeable sediments and/or volcanic rocks, take place in the upper parts of submarine hydrothermal systems.

- Description: Chemically modified electrodes, constructed by incorporating oxomolybdenum(V) phthalocyanine (OMo(V)(OH)Pc, Pc = phthalocyanine dianion) into graphite powder were used to catalyse the oxidation of cysteine. Solution catalysis of cysteine by oxomolybdenum(V) tetrasulfophthalocyanine, [OMo(V)(OH)TSPc]4−, was also investigated. A considerable reduction in overpotential for cysteine oxidation was observed. Cysteine oxidation occurred at 0.26 and 0.28 V vs. Ag/vbAgCl for catalysis by Omo(V)(OH)Pc and [OMo(V)(OH)TSPc]4− respectively as opposed to 0.77 V vs. Ag/vbAgCl observed on CoPc chemically modified electrodes. The anodic peak currents vary linearly with cysteine concentration in the range 0.02 to 0.08 mol dm−3 and 0.008 to 0.02 mol dm−3 for [OMo(V)(OH)TSPc]4− and OMo(V)Pc respectively.

- Description: Issues of group identity and prejudice have played a large role in the history of South Africa. To examine differences between White English- and Afrikaans-speaking adolescents within the context of the "new" South Africa, data was collected from 553 high school students using a questionnaire which assessed aspects of these groups' perceptions of themselves (their identities), attitudes toward other racial groups (their prejudices), and beliefs about their rapidly changing socio-political environment. A discriminant function analysis conducted with these variables correctly identified group membership at a rate much higher than chance (p < .00001). Post hoc univariate analyses indicated that compared with Afrikaans-speakers, English-speakers demonstrated significantly less identification with their own culture, less racial prejudice but also less willingness to make retribution to those who were oppressed by Apartheid, and less concern/confusion over the recent changes which have taken place in the country. Descriptive and correlational analyses also provided additional, valuable information regarding the variables assessed in the study. Overall, the results seemed to indicate that the adolescent subjects of this study find themselves in a state of transition.

An investigation into some critical computer networking parameters : Internet addressing and routing

- Description: This thesis describes the evaluation of several proposals suggested as replacements for the currenT Internet's TCPJIP protocol suite. The emphasis of this thesis is on how the proposals solve the current routing and addressing problems associated with the Internet. The addressing problem is found to be related to address space depletion, and the routing problem related to excessive routing costs. The evaluation is performed based on criteria selected for their applicability as future Internet design criteria. AIl the protocols are evaluated using the above-mentioned criteria. It is concluded that the most suitable addressing mechanism is an expandable multi-level format, with a logical separation of location and host identification information. Similarly, the most suitable network representation technique is found to be an unrestricted hierarchical structure which uses a suitable abstraction mechanism. It is further found that these two solutions could adequately solve the existing addressing and routing problems and allow substantial growth of the Internet.

An investigation into teachers' perceptions of female secondary school principals in Kwazulu-Natal

- Description: There are few female teachers who hold principal positions in schools, especially in secondary schools. This study investigates teachers' perceptions of secondary school female principals' leadership abilities and styles.It also investigates whether teachers' perceptions are influenced either by their sexes or experience or lack of experience of working with female principals. The reseacher hopes that this research findings will help to either: develop and improve female leadership (where it is found to be wanting); and or influence authorieties to appoint more female teachers to head secondary schools. The literature surveyed revealed that the appointment of principals in seconday schools is discriminatory against female teachers. It further revealed that principals (mainly male) do not prepare female teachers for management and leadership positions. As a result female potential leaders become demotivated. This is unfortunate as research has found that female principals are as effective as leaders as male principals are. One disadvantage of having a small number of female leaders in education is that this results in an education that only reflects the male perspectives and values. This in turn alienates girls' perspectives from education. In order to establish teachers' perceptions of female secondary school principals a survey of the percptions of teachers in the Maphumolo circuit of female principals in this area was first carried out by means of a questionnaire. This was followed by a case study of one female principal. In depth, semi-stuctured interviews were undertaken with the principal and three teachers working with her in order to establish this principal's leadership style and the teachers' feelings towards her. A statistical analysis of the survey and a conten~ ~alysis of the case study were carried out. These revealed that the majority of teachers perceive female principals as effective and transformational leaders. These perceptions were found to be minimally influenced by either the teachers' sexes or experience of working with female principals. The..majority of those teachers who perceived female principals negatively tended to be males and to be from a group of teachers who had never worked with female principals. Recommendations for the increase of the number of female principals in secondary schools and for the improvement ofleadership in these schools are made.
