Abstract: Although several studies have recommended removal of secondary components of magnetic remanence by zero-field cycling from room temperature to a temperature much lower than the low temperature transition for magnetite (about 120 K), the method has not become a standard routine technique. This is partly due to the poor understanding of the behavior of magnetite particles at the low-temperature transition zone. Previous experiments by other researchers have used magnetite powders. In such powders it is always possible to attribute any discrepancy between the results observed and theory to possible existence of magnetostatic interaction effects or existence of elongated particles in samples presumed to contain only equant particles. Such factors need to be eliminated in order to have a better understanding of the low temperature behavior of magnetite particles. Low-temperature magnetic properties of lithographically produced arrays of both interacting and noninteracting cubic magnetite particles as well as those from powder particles have been measured as part of this study. A gradual increase in the amount of saturation isothermal remanent magnetization (SIRM) lost at the Verwey transition Tv with increasing particle size in the pseudo-single-domain size range has been observed. This behavior is consistent with the vortex state domain structure. The grain size dependence of the amount of SIRM lost at Tv is most probably what previous researchers reported as a magnetic memory particle-size-dependent trend. Magnetic memory measured during the cooling and warming process is shown to be a stress-related phenomenon. Such measurements could be useful in assessing the nature of stress in a magnetite sample.

Abstract: There has been sufficient concern in Botswana about the family that it has become a subject of several radio debates and panel discussions. Recently, a National Law Reform Committee was set up to look into, among other things, the existence of both customary and statutory laws relating to marriage. Whatever the success of the Law Reform Committee will prove to be in the future, for now, it does represent a significant formal recognition by government that there are serious problems in this area of concern. By reflecting on field experiences, teaching as well as public discussions of the subject, this paper calls attention to an area of social research which is contemporary and relevant, but which has not enjoyed systematic attention hitherto. The aim of this paper will be to illustrate how the modern Tswana family as it is found today throughout the country, to a lesser or greater extent, does not correspond with its modern ideal as well as its legal conception. This departure from the defining characteristics creates problems for family life and in the long run have retarding effects on community, and by extrapolation, National development potentials.

Abstract: During the South African War of I899-I902 the Kgatla people and their leader, Linchwe I, became deeply involved in fighting on Britain's side against the Boers, and the history of their campaign helps in many ways to explain why some blacks chose to take part in the white man's war'. In contrast to recent studies which deal generally with black participation in the war, the account that follows examines the role of one specific African group and explains, in detail, how one black leader weighed his options, took deliberate action and tried to direct events in which he and his regiments were involved. Special attention is also focused on the Kgatla choice between Boer and Briton, their expectations when entering the war, their actual role in the fighting and their gains from participation balanced against the cost. Linchwe's Kgatla provide a particularly instructive case study, because in the years preceding the war part of his people were resident in the Bechuanaland Protectorate under British administration, while the other part lived in the western Transvaal under the rule of the Zuid Afrikanische Republiek (ZAR). The fact that they straddled two colonial worlds, which between I899 and I902 collided in war, was a major factor in Kgatla actions and deliberations. As 'partitioned Africans', directly familiar with and affected by both white colonial combatants, the Kgatla and their experience suggest many possible reasons why other Africans were involved in the fighting, whether against Boer or Briton. For decades scholars and amateur historians have noted Kgatla participation in the South African War, but only recently has research begun to reveal the extent and significance of the Kgatla (and African) role in the conflict. The research of Schapera, Ellenberger, Hickman, Teichler and Truschel has yielded much evidence related to Kgatla military activity beginning with the battle of Derdepoort (25 November 1899).

Abstract: The two universities - University of Botswana (UB) and National University of Lesotho (NUL)-have their origins in the University of Botswana, Lesotho, and Swaziland (UBLS). The University of Botswana came into existence in 1982, while the National University of Lesotho was established in 1976. The Department of African Languages and Literature is one of the oldest in the humanities faculty. The two major languages and literatures, Setswana and Sesotho, have so much in common that one can hardly discuss one without the other. The Department of African Languages and Literature of the University of Botswana offers a course, AL305-''Individual Project Work on a Literary or Linguistic Topic." Similarly, the National University of Lesotho offers AL304-"Project Work on a Literary or Linguistic Topic." Students are required to submit dissertations in partial fulfilment of the Bachelor of Arts degree. Between 1973 and 1983, seventy-three dissertations on modern and traditional literature were presented, including forty-one in Sesotho and thirty-two in Setswana. Copies are kept in the special collections of the University libraries. For the purposes of this bibliography, the Setswana dissertations written at UBLS and the University of Botswana and Swaziland (1976-82) are included under UB, and the Sesotho dissertations of UBLS are included under NUL.

Abstract: This paper examines the challenges and opportunities that present themselves to the Southern African region as far as free regional and international trade is concerned. The focus of the paper is on the Southern African Development Community (SADC), the one regional organization to which all Southern African countries are members. Issues that need to be dealt with include the existence of a total of three regional groups all concerned with trade: SADC, the Southern African Customs Union (SACU), and the Common Market for Eastern and Southern Africa (COMESA) and concern over productivity and competitiveness of the region internationally. The SADC region needs to move swiftly towards free regional trade as part of the process of gearing up to the ever increasing global competition. Domination of the region by South Africa is also alluded to briefly. There is very little discussion on the Democratic Republic of Congo and Seychelles, the latest members of SADC. However, data on these two countries is presented in the three tables contained in this paper. URI: http://hdl.handle.net/10311/836 Files in this item: 1

Abstract: Solar energy is finding wide application via several energy-saving devices and systems. Its use, especially in rural areas, can often be limited by the non-availability of complete information on insolation data. In this investigation, both the mean extraterrestrial and terrestrial radiations were calculated for three zones in Nigeria. These zones were assumed to be dependent mainly on the latitude, L. The isotropic model was employed for the computation of the diffuse and ground reflected components of radiation. Consequently, the total insolation was obtained for various inclinations of the collector surface. It was found that three solar energy seasons exist for each zone. For maximum total incident radiation, a different collector inclination is ideal for each solar energy season. However, for all year round applications, a fixed inclination varying between L and (L+10) degrees is recommended. URI: http://hdl.handle.net/10311/672 Files in this item: 1

Abstract: This paper traces historical events in the development of primary science in Botswana. It identifies changes that have taken place from 1969 to 1989. Prior to 1969, the word science in primary schools was non-existent. Primary pupils were taught nature study which emphasised hygiene and plants. The revised 1982 primary science curriculum coincided with the period of rapid industrial developments in Botswana. The purpose of including physical science concepts in the primary science curriculum was to prepare the nation for industrialisation. The purpose of including environmental concepts in the primary science curriculum was to raise the environmental awareness of the nation. URI: http://hdl.handle.net/10311/1047 Files in this item: 1

Abstract: The use of solar energy is well established for low-grade thermal applications such as water heating and purification. In many of the solar systems, the collector surface located in the Northern Hemisphere faces the true south direction. However, there are occasions in which the radiation received by the collector at various orientations is desirable, such as a collector incorporated with a tracking system. The data for such situations are not available for several solar farms in Nigeria. Consequently, in this study, the average global radiation on flat surfaces was determined for three zones in Nigeria. The total insolation was obtained while the surface azimuth angle was varied between 0° and 75° at 15° intervals. The results are presented for three inclinations of the collector surface, namely L − 10, L, and L + 10 degrees respectively. URI: http://hdl.handle.net/10311/671 Files in this item: 1

Abstract: In many African countries, including Botswana, the driving schools and instruction given to pupils are uncontrolled. Thus, this paper presents the results of an investigation into the level of professional training offered by the driving schools in Gaborone. A total of 400 randomly selected drivers completed questionnaires on their training, accident records, and L-tests. Male trainee drivers received more instruction than females, and there was some indication that the pass rate on L-tests was lower for female drivers. Also, the pickup van forms the majority of the national vehicle population. It accounts for almost 40% of the accidents but is presently not used for training in the commercial driving schools. It is concluded that the quality of professional instruction in driving schools needs improvement so that learners can be encouraged to take training from these institutes.

Abstract: In this paper we trace how Gaborone has grown from a very small village to the capital city of Botswana in a period of less than 30 years. Attention has been given to how careful design of master plan concepts has shaped the city and responded to the needs and aspirations of the residents. Through appropriate and enabling urban- development policies, standards and codes, a very amenable environment has been created. The city can boast of adequate and modern civic and commercial centers; modern functional infrastructure including water, electricity, roads and sewage systems; access to land for virtually all people; adequate housing provided by both the public and the private sectors and for the low income, the adoption of a very successful program of squatter upgrad- ing and self-help housing. Through careful management and development control practices, city growth has been contained quite well in spite of rapid development and the future of the city looks quite bright.

Abstract: Our motivation and inspiration to undertake this aspect of the phonology of Setswana is derived from research in Setswana phonology by Creissels (Notes, 1991-1992) and from the Bantu languages phonology by Bastin (1983). The reanalysis of the phenomenon that we earlier treated under what the two linguists describe generally as "imbrication"l (cf. Chebanne, 1993, ACAL 24), and which means an affixal imbedding which transforms morphemes has yielded new mterpretations on the Setswana data. We are now inclined to call this phenomenon "intersuffixing", which refers here to the adjustment of positions and forms undergone by verbal suffixes according to morpho-phonological rules. The two terms, intersuffixing and imbrication, actually do not mutually exclude each other. Imbrication may result after certain suffixal permutations in the process of intersuffixing have occurred.

Abstract: The 1990s began with a commitment to children through the adoption, by the United Nations General Assembly, of the Convention on the Rights of the Child. This Convention set the minimum standards of protection for children's survival, health and education; protection against exploitation at work; protection against the degradations of war; and protection against physical and sexual abuse. By 20th July, 1994, 163 countries had ratified the Convention and 11 other countries had signed but not yet ratified the convention (World Health Organization, 1994:1).

Abstract: This article is about the way people of Tswana origin related with non Tswana speaking people and how they referred to them. It talks about how some of the non Tswana speaking people especially the Whites or Makgowa came into being as seen by the Tswana and other inhabitants of Southern Africa. The article also talks about trade, Traders and Travellers among the Tswana, other Africans in Southern Africa and the Whites (Makgowa,the Boers (Maburu), the Portuguese in Southern Africa. The barrier between "us" and "them" (or in postmodern-speak, "the other") in Sotho- Tswana language is said to be most clearly demarcated by the mo-! ba- (singular! plural) distinction in noun prefixes given to "us" people and the le-! ma- prefixes given to "them" people. This being a mirror image of Nguni usage, where "us" are ama- and "they" are abe-. URI: http://hdl.handle.net/10311/1102 Files in this item: 1

Abstract: The traditional developed earth as one of the most important construction materials by taking cognizance of the strength requirements, durability of resulting structures and the environmental concern in processing and using the material. Overthe years, however, modern earth construction has replaced the traditional methods. Unfortunately,these methods are also accompanied by high energy consumption and environmental degradation.This paper examines the methods of improving earth construction in two major villages in Botswana.Tests with different stabilizers showed that only certain proportions were effective and it was concluded that the traditional earth construction may be improved by using certain ratios of cement and lime as stabilizers.

Abstract: In both precolonial and Westerm forms of schooling, education was a crucial medium of construction and articulation of ideas concerning the role and behaviour of women. Precolonial education reproduced and maintained sharp gender differentiation in the division of labour. Socialisation and women's own internalisation of their role and position in society, upheld dominant male ideology and subordination of women. Under colonialism, missionary and colonial education renegotiated but did not fundamentally change the role and position of women. However, it inadvertently also provided women with ways to move out of the household sphere into the wider labour market, albeit as unequal participants. Missionary education strictly separated the sexes and rested on the continued association of women with Victorian notions of 'domesticity'. The concept of ideology is used in this paper to tease out and highlight the gender dynamics which have influenced and directed education among Batswana.

Abstract: This paper is about the introduction of western education by Missionaries in Africa. These European Missionaries left their homes for religius reasons, to convert the "heathens" to the christian religion. Convertion to christian religion faced many hurdles like language barriers, cultural beliefs and that the people to be converted were illiterate. The converts to be had to be taught how to read and write to be able to interpret the bible. The education offered by Missionaries was tended to be scriptural in nature because the intended converts were supposed to read and understandthe great book of God - the Bible. Emphasis was on religious studies. Missionaries targeted African leaders such as Chiefs in their endeavor to convert and also to introduce western education. Once the leaders were convinced and converted in the new religion and education, they would influence the dissemination of the new faith to their groups or tribes. Western education was introduced in the manner such as described above among Batswana. The Missionaries who introduced western education and christianity were members of the London Missiory Society (LMS) formed in 1795 and these were Dr. Robert Moffat and Dr. Livingstone.

Abstract: The design and construction of infrastructure facilities such as road network, water supply and sewage disposal in Botswana, have often been done in a top-bottom fashion where the government or local authority decides what is good for the community. While the design and construction of infrastructure facilities require technical knowledge, heavy equipment and proper supervision, their management hardly requires these resources to the same extent. This offers the beneficiaries of the facilities an opportunity to manage their day-to-day operations and maintenance. Reports on an approach adopted to engage the community in the management of local road network, water supply and sanitation in three major villages in Botswana. It analyses the method previously employed in managing these facilities and outlines the benefits which will accrue when this approach is fully operational. Concludes by underlining the fact that, for community-managed facilities to work, the people in the community need to participate in all the stages of the project (i.e. planning, design, construction and eventually maintenance).
