Fertility transition in Lesotho : the recent trends, socioeconomic factors and proximate determinants.

Shale, Mashale. January 2011 (has links)
There is a general perception that fertility has been declining over a decade in Lesotho, and this has sparked the debate that fertility transition is drawing closer in Lesotho. The growing concern was stimulated by limited studies showing the effect of socio-economic factors on fertility in Lesotho and variations in proximate determinants. The paper examines recent fertility trends in Lesotho using various demographic techniques of fertility estimation and determines whether the onset of fertility transition has begun in Lesotho. The secondary aim is to assess and control errors in the Lesotho Demographic and Health Survey of 2004, thus providing robust and reliable estimates. The analysis utilizes the secondary data from 2004 Lesotho Demographic and Health Survey (LDHS). The data set comprised of a sample of 7095 women who participated in the survey. The use of 1996 Lesotho Population Census and 2002 Lesotho Reproductive and Health Survey were made to facilitate comparison with 2004 LDHS, and to provide differentials and measure changes over time in fertility. The P/F ratio method developed by Brass and the modified version, Relational Gompertz Model are employed and used to assess the quality of data as well as determining fertility levels and trends. The findings reveal that the overall fertility among women in Lesotho during 2004 LDHS is 4.02. Application of different methods depicts that fertility remains high in Lesotho, although considered moderate according to sub-Saharan standards. Despite the fact that TFR is high, overall fertility decline is evident. The estimates of fertility range between 3.5 and 5.6 depending on the technique in use. The reason for the high observed fertility is that women in the rural areas still cherish quite a substantial family size. Nevertheless, changing acceptance and perception of using contraception, delayed marriage, high levels of education and economic development among women in Lesotho contributes considerably to fertility declines in Lesotho. As a result, disparities that continue to propel fertility levels within population groups incite reassessment of existing research and policy so as to enhance development strategies as well as action programmes. / Thesis (M.A.)-University of KwaZulu-Natal, Howard College, 2011.

Anti-bacterial and anti-inflammatory activity of medicinal plants used traditionally in Lesotho.

Shale, Thato Lucy. 10 December 2013 (has links)
A significant potion of the population in Lesotho relies on traditional medicine to meet its health care requirements. Traditional healers and herbalists were interviewed from Qacha's Nek (Highlands) and Mohale's Hoek (Lowlands) districts in Lesotho on plants used by the Basotho in traditional remedies. Fifteen plants were reported to be used for bacterial infections while thirteen plants were used for diseases associated with inflammation . Plant roots were most often used to make water extracts. Mainly high altitude plants are used with lowland healers obtaining most of their plant material from the highlands, either by collecting them or buying them from highland gatherers. Leaves and roots of plants used to treat bacterial infections were extracted with hexane, methanol and water and the respective extracts screened at 100 mg ml¯¹ for anti-bacterial activity using the disc diffusion bioassay. Seven species displayed very high anti-bacterial activity against both Gram-positive and Gram-negative bacteria. A number of plant extracts had medium inhibitory activity, mostly against Gram-positive bacteria. This activity was mainly found in the root extracts. Six of the thirteen plants screened for anti-inflammatory activity using the cyclooxygenase-1 (COX-1) bioassay had activity above 90%. Hexane and methanol extracts were the most active while water extracts usually had lower activity. Malva parviflora, Eriocephalus punctulatus and Asparagus microraphis exhibited high anti-inflammatory activity from hexane, methanol and water extracts made from leaf and root material. High anti-bacterial activity was also recorded from M. parviflora and E. punctulatus hexane, methanol and water extracts. An investigation on seasonal variation and plant part substitution in medicinal activities for these plants was carried out. Extracts of M. parviflora collected between June 1999 and July 2001 showed variation in anti-bacterial activity. Extracts made from leaves and roots inhibited the growth of both Gram-positive and Gram-negative bacteria. More bacterial strains were inhibited by extracts made from roots collected in cooler months. However, a trend in seasonal activity was not evident for either the roots or leaves because there was no detection of activity in some of the extracts made within the same months or seasons of the adjacent years. Variation in anti-inflammatory was detected for M. parviflora extracts. E. punctulatus leaf extracts did not exhibit any seasonal variation in anti-bacterial activity. Anti-inflammatory activity of E. punctulatus showed seasonal variation with the highest activity noted when material was collected during the cooler months and a decline in activity when collections were made during the warmer months. Hexane, methanol and water extracts made from leaves and roots of A. microraphis did not show any seasonal variation in anti-inflammatory activity. Thus, M. parviflora and E. punctulatus should be collected during the cooler months while A. microraphis can be collected throughout the year. Traditional healers, herbalists and vendors need to be encouraged to use aerial parts in substitution of ground parts which are reported to be highly utilized. Effect of storage on anti-bacterial and anti-inflammatory activities of M. parviflora, E. punctulatus and A. microraphis were monitored. Dried, ground leaf and root material of the three plants was stored in a cold room, at room temperature and in the Botanical Garden where the material was exposed to high and large changes in temperature. Dried hexane and methanol extracts made from leaves and roots of these plants were stored in a cold room and at room temperature. Initially, storage of the plant material under the three storage conditions caused an increase in antibacterial activity of the hexane, methanol and water extracts made from leaf and root material of M. parviflora and E. punctulatus. Storage for a longer period resulted in a decrease in inhibitory activity. TLC fingerprints developed from hexane and methanol extracts made from M. parviflora and E. punctulatus stored in a cold room and at room temperature showed a consistent number and colour of spots during the initial storage period. Prolonged storage resulted in a decline in the number and colour of detected spots. The stored hexane and methanol extracts made from leaves and roots showed a similar trend of increases and decreases in anti-bacterial activity as well as changes in spots with the storage of the extracts. Testing of the effect on anti-inflammatory activity of hexane, methanol and water extracts made from leaves and roots of M. parviflora, E. punctulatus and A. microraphis showed no change in inhibitory activity of hexane extracts obtained from the material and the extracts stored at the three storage conditions. Methanol and water extracts made from leaves exhibited an increase in activity with prolonged storage. Generally, the stability of the inhibitory activity was longer for the stored dried material than the plant extracts. Isolation of biological active compounds from M. parviflora was not successful due to loss in anti-bacterial activity as a result of collection of plant material from a different locality. Anti-inflammatory compounds could not be isolated due to insufficient amount and the synergistic effect of the active compounds . The purified compounds exhibited loss of activity following HPLC purification which then re-appeared upon recombining the fractions. A number of compounds were detected from essential oils of E. punctulatus using GC. Fractions containing these compounds gave positive anti-bacterial activity in the disc-diffusion , bioautographic and MIC bioassays as well as high anti-inflammatory activity with COX-1 and COX-2 anti-inflammatory bioassays. No anti-inflammatory compounds were isolated from A. microraphis. / Thesis (Ph.D.)-University of Natal, Pietermaritzburg, 2003.

Primary school teachers' understanding and interpretation of problem-solving : how it is promoted in science lessons, why and why not?

Moeletsi, M'aseapa Mookho Violet. January 2005 (has links)
This study explores how Lesotho primary school teachers understand and interpret problem-solving (PS) and how they teach and support it. Observation schedules and semi-structured interviews were used to collect data from classrooms, teachers and learners. The findings revealed that teachers have considerable understanding of (PS) and value it but are not teaching it. Teachers attribute this to their lack of knowledge, the difficult conditions in their schools, policy constraints (such as assessment) and their own habits and behaviours. However, the data also indicated that teachers, with support, can successfully design and teach appropriate lessons in their schools, raising issues about their knowledge, beliefs, identity and structures. / Theses (Ph.D.)-University of KwaZulu-Natal, Durban, 2005.

Closing the gender gap : examining the reasons for performance differences in mathematics between Std 7 girls and boys in the Qacha's Nek District - Lesotho.

Molise-Sehlabi, 'Make Aloyisa 'Maselloane. January 2002 (has links)
There is a concern in Lesotho about inequalities in different sectors including inequalities that exist between females and males in schools. Closing the gender gap between males and females, girls and boys is the government's priority, hence the recent Gender and Development Policy, 2002. The project was conducted with the purpose of exploring the reasons that contribute to pupils' gendered performance in mathematics. In this regard, the focus was put on reasons behind girls' poor performance in mathematics. This report presents and discusses the results of a research which was conducted in Qacha's Nek - Lesotho. The project made some observations based on the questionnaire data gathered from four primary schools. The data provided some useful insights into girls' attitudes, behavior and perceptions towards mathematics, and it also provided insights into teachers' attitudes, expectations and perceptions about girls and their learning of mathematics. The research also provided evidence that there are different social factors that contribute to girls' poor performance in mathematics. Some of those factors concern parents, teachers, classroom process, peers and girls themselves. The analysis of the results and subsequent discussion suggests reasons that may be useful in terms of helping to explain pupils' gendered performance in mathematics and in the continued search for strategies that could improve girls' poor performance in this subject. Schools could be creative in the strategies that they can adopt to tackle gender differences. With this in mind, teachers and pupils were asked to suggest possible solutions that could be employed in trying to combat the problem of the gendered performance in mathematics hence noticeable improvement in girls' performance in this subject. / Thesis (M.Ed.)-University of Natal, Durban, 2002.

The nature and extent of implementation of music education : a case study of Mohokare Primary School and Hoohlo Primary School in Maseru, Lesotho.

Motsoane, Phatsa M. January 2004 (has links)
This study investigated the nature and extent of implementation of music education in Lesotho primary schools in Maseru district. A case study conducted focused on Mohokare LEC Primary School and Hoohlo ACL Primary School. The findings from the study suggest that teachers at both schools had a relatively positive attitude towards music education and that they think the subject area should be taught in their schools. However, they suggest that effective implementation of the subject is hampered by several structural, contextual and curricular factors in the education system and the schools themselves. For example, preparations for implementation of music education were not sufficient (e.g., human and other resources were not in place). Teachers were not adequately trained in the subject itself as well as in its pedagogy. This has implications for the Ministry of Education and Training (MoET) to strengthen pre-service and in-service music education. In addition, a clear music education policy should be drawn up to guide schools and district offices in the implementation of music education. This should be followed by a provision of adequate and appropriate resources needed for the process. / Thesis (M.Ed.)-University of KwaZulu-Natal, Durban, 2004.

Girls and science in the Lesotho secondary schools : a study of the reasons for low participation rates by girls in the Mohale's Hoek district.

Moletsane, Mamorakane. January 2002 (has links)
It has been discovered that in many countries, both locally and internationally, girls have low participation rates in science at secondary school level. This thesis examines the factors that underscore the persistence of girls' low participation rates in schools. The major reason for this examination is to establish ways in which secondary school teachers, interested individuals or groups of people, and the ministry of education in Lesotho can manage this problem. Kelly (1981) argues that causes of girls' negative attitudes towards science are multifaceted. Thus, in attempting to understand these causes and to develop strategies to manage this behaviour, a single approach, which focuses on student-teacher classroom interaction, was considered. This thesis therefore, seeks to investigate the responses of girls and science teachers in schools with least numbers of girls having opted for science in the last five years. Due to less numbers of science teachers in schools, I involved in this study, all those found in schools surveyed. To survey girls' responses to this problem, I drew a random sample of both those who have opted for, and those who have opted out of science. I then used a self-administered questionnaire as the research instrument for this study. Basing myself on my judgement's analysis, I therefore concluded that gender discrimination is the major source of girls' negative attitudes towards science in Lesotho, the country that condones female subordination. The unfavourable learning atmosphere that male teachers create for girls in science lessons, such as, the harassment, the harshness, deprivation of opportunity to participate in class, to use the laboratory equipment and other ways and means of ill-treating and frustrating girls are all a result of male domination. A number of recommendations to manage this problem have therefore been proposed. / Thesis (M.Ed.)-University of Natal, Durban, 2002.

Exploring the disjunction between spoken and written English among second language (L2) learners at St Charles high school, Lesotho.

Molapo, Mpheng Patricia. January 2002 (has links)
This research project was primarily a qualitative investigation, the purpose of which was not to test a particular set of hypotheses, but rather to develop an exploratory analysis of the disjunction between spoken and written English among pupils at St Charles High School. In light of the lack of empirical and exploratory research on the use of English as a second language in Lesotho, the study aimed to investigate pupils' and teachers' perceptions on the use of English as a subject and medium of instruction. Chapter 1 presents an introduction of English and the formal type of education in Lesotho by missionaries just before the middle of the nineteenth century. Although English is regarded as the 'language of power' nevertheless the teaching and learning of the language has its own problems and teachers and pupils' experiences with second language learning in different local and international contexts are discussed in Chapter 2. The study used both qualitative and quantitative methods to gather and analyse data. A case study approach was employed using a range of instruments to collect data relevant to the aim of this project. The findings show that although pupils are generally proficient in spoken English and appear to understand the spoken language fairly well, assessment of their written exercises and during lesson observations indicates that their fluency in English is not related to their performance in written English. Therefore, fluency in English language does not necessarily form a sufficient basis to describe pupils as competent in English (L2). This does explain the possible difference between spoken and written English. The thesis does not offer tips for teachers nor are methods prescribed about how to teach English as a second language. Although limited to a particular high school (the detail and context of which are described in Chapter 3), much of what was found and the subsequent recommendations may be of value to improve the teaching and learning of English. I hope that this study, which was very much a pilot in nature, will help to highlight issues that might be addressed in more detailed studies in the field of second language learning. / Thesis (M.Ed.)-University of Natal, 2002.

Factors that enable high pass rates at Cambridge Overseas School Certificate (C.O.S.C.) level at Botha-Bothe High School in Lesotho.

Leu, Mokete Moses. January 2004 (has links)
This study sought to investigate factors that enable high pass rates at Cambridge Overseas School Certificate (C.O.S.C.) level at Botha-Bothe High School in Lesotho. The focus of the study has been on three broad possible factors, namely the nature of leadership within the institution, the relationships between administration and teachers, amongst the teachers and between the teachers and learners, as well as resources available in the school. The study used a triangulation of three instruments: interviewing, observation and document analysis to collect data. These three instruments helped the researcher to collect proof-checked information and arrive at concretized conclusions. The Principal, Deputy-Principal, HODs and teachers who participated in interviews, handed to the researcher the necessary documents and took the researcher around to different teaching centres. Having investigated and correlated all the results, the researcher concluded that the following are possible factors that could improve pass rates. The first factor is a sound leadership that allows interaction, that manages time, that motivates other stakeholders, and that includes its subordinates in decision-making. The second factor is warm relationships between management and staff, amongst the academic staff and between teachers and students. The third factor is the availability and good management of resources (human and material). / Thesis (M.Ed.) - University of KwaZulu-Natal, Durban, 2004.

The management of teaching and learning resources in primary schools.

Mohono, 'Mapaballo Jeannette. January 2010 (has links)
This study sought to explore the management of teaching and learning resources in the context of free primary education in Lesotho primary schools. In addressing this purpose the qualitative methods of data production were used. The participants were the principals and teachers from three schools. Qualitative data was collected through individual semi structured interviews, observations and document analysis. This was analyzed using qualitative thematic approach. The findings showed that the schools studied had functional resource management committees. However the schools experienced a high shortage of resources. These resources largely come from the government but they are delivered late in most cases. Therefore teachers find themselves having to improvise and to use resources in turns. The study concludes that schools cannot rely on government alone in terms of teaching and learning resources. / Thesis (M.Ed.)-University of KwaZulu-Natal, Edgewood, 2010.

Solid waste management in low and high income residential areas of Maseru : a comparative study of Maseru West and Seapoint.

Seholoholo, Masechaba. January 1998 (has links)
Waste management has received very little attention in Lesotho' s Development Planning. Lack of environmental policy and environmental framework law has resulted in waste being illegally dumped. Inadequate services in the country, coupled with increasing population in the urban areas due to rural-urban migration, has led to litter being a serious environmental problem in the whole country, especially in the urban areas. This study aims to analyse the defects of the waste management strategies in Maseru by investigating the waste management systems employed in two residential areas of different income levels. In addition, this thesis attempts to evaluate the impact of socioeconomic and educational factors on solid waste management practices in Maseru. An investigation into trends or similarities in the services rendered by the Maseru City Council was carried out and compared with the literature reviewed. A survey was conducted as two case studies, mainly to assess the present coverage and the standard of refuse generation, collection and disposal service. Waste was collected from the two study areas and compared in terms of the type and amount of waste. generated. The major factors influencing waste generation were found to be the gender and educational level of the household head, income level of the household and the household size. These were found to be proportional to waste generation and inter-related. In this regard, that families headed by men were found to have higher incomes than those headed by women and were found to produce more waste. Furthermore, in households where the household head had attained a higher level of education, income levels increased, there was a concomitant increase in waste generation. In general, high income residential areas generated more waste than low income residential areas. Large families use more money and consume more food than small families, thus generate more waste. The major component of waste was largely paper and plastic, but glass, cans and organic materials were also recorded. In general, waste management in Maseru (Lesotho) was found to be very poor because of lack of policy and contradicting and scattered sectoral laws dealing with waste management, lack of urban planning and infrastructure. More importantly, waive of laws relating to waste has resulted in land degradation due to illegal dumping and littering. / Thesis (M.Sc.)-University of Natal, Pietermaritzubrg, 1998.
