Abstract: This paper reviews the usefulness of the project management approach in promoting organisational and managerial flexibility in traditional organisations in developing countries. Three aspects of project management, viz. organisational structure, organisational behaviour, and planning and control tools, that have immense potential to alleviate these problems are reviewed. The need for indigenous managerial approaches in developing countries, and addressing some of the problems that hinder organisations from exploiting the potential benefits of the project management scheme are discussed.

Abstract: Grading is a central component of educational assessment because it is through grading that a student’s performance is judged as having satisfied the requirement for a given unit or grade level. Accurate determination of the cut-off point between adjacent grades is thus critical in ensuring that a letter grade assigned, and ultimately the certificate given, are a true reflection of a candidate’s mastery of the assessed subject matter. Different systems are used to establish cut-off points: each method with its own advantages and disadvantages. In Botswana, the Angoff grading model was adopted following the introduction of criterion referenced testing in 1997. This model was implemented in order to correctly reflect the achievement level of primary school graduates and at the same time, maintain performance standards from year to year. While this model appears to have robust the theoretical foundations, its practical application and success are highly constrained by contextual country-specific factors. This paper outlines the observed practical limitations of the Angoff grading system in Botswana. URI: http://hdl.handle.net/10311/1115 Files in this item: 1

Abstract: To deliver project effectively is of paramount importance because most of the world population depend on services delivered by projects. Reports from various countries around the world, including Botswana, still indicate poor project delivery. Several causes may be advanced including ineffective project control. Devising means to alleviate the control problem is therefore, of great importance. Scholars and practitioners have suggested various techniques that monitor and keep track of projects. One of them is the earned value analysis(EVA) which touted by many as an efficient yet effective control system because of its ability to control scope, cost and time. Based on this premise, the study reported in this paper investigated possible use of EVA in building projects in Botswana. The investigation was two fold, firstly, through a questionnaire, quantity surveyors (QSs) were requested to indicate whether they have use the EVA on any building project in Botswana. Results from this survey indicated that EVA is not used at all in Botswana. In fact, majority (63%) of the QSs have not heard of the system before. The second phase of the study investigated its possible use, that is, if using EVA is more adventageous than the convectional control method (CCM). Results indicated that EVA system provide quality information that was well structured, more objective, and easily accessible to all key stakeholders in a timely and understandable manner. However, to use EVA system several challenges were also indentified which included firstly, the need to train the key players in the EVA technique.; the need to change the project regime from arms-length to a cooperative on to allow transfer and sharing of information in the design and construction phases of a project; increasing the use of IT; completing design before tendering even for other trades; and nominating sub-contractors as soon as the main contract is appointed.

Abstract: Malnutrition affects physical growth, morbidity, mortality, cognitive development, reproduction, and physical work capacity, and it consequently impacts on human performance, health and survival. It is an underlying factor in many diseases for both children and adults, and is particularly prevalent in developing countries, where it affects one out of every 3 preschoolage children. A well-nourished child is one whose weight and height measurements compare very well with the standard normal distribution of heights and weights of healthy children of the same age and sex. Factors that contribute to malnutrition are many and varied. The objective of the present study is to evaluate the level of malnutrition and the impact of some socio-economic and demographic factors of households on the nutritional status of children under 3 years of age in Botswana. Factors included: the number of children under 3 years of age in the family, occupation of the parents, marital status, family income, parental education, maternal nutritional knowledge, residence location (urban or rural), gender, and breastfeeding practices. The study was a cross-sectional descriptive survey using a structured questionnaire and measurements of weight and height. Four hundred households and mothers of children under three, representing the 23 Health Regions of Botswana, participated in the study. Reference standards used were those of the National Center for Health Statistics (NCHS). EPI Info software (version 5) was used for data entry and analysis. The results show that the level of wasting, stunting, and underweight in children under three years of age was 5.5 %, 38.7 %, and 15.6 % respectively. Malnutrition was significantly (p < 0.01) higher among boys than among girls. Underweight was less prevalent among children whose parents worked in the agricultural sector than among children whose parents were involved in informal business. Children brought up by single parents suffered from underweight to a significantly (p < 0.01) higher level than children living with both parents. The prevalence of underweight decreased significantly (p < 0.01) as family income increased. The higher the level of the mother’s education, the lower the level of child underweight observed. Breastfeeding was found to reduce the occurrence of underweight among children. The study findings imply that efforts for redressing child undernutrition issues in Botswana should focus on factors associated with development outcomes such as maternal income, maternal education, and the creation of employment or economic engagements that do not compromise important child care practices such as breastfeeding.

Abstract: The results discussed in this report are part of a larger study conducted among the students of the University of Botswana regarding their knowledge, attitudes, and behaviors related to HIV/AIDS. The study triangulated survey methods and focus group discussions. Five main areas were investigated: knowledge and personal experiences of HIV/AIDS, sexual behavior and practices, perceptions about risky sexual behavior on campus, and factors that influence the spread of HIV. This article reports high levels of risky behaviors such as alcohol and drug abuse; unprotected sex; frequent change of sexual partners; sex for financial gain, for prestige, for good grades, to relieve stress, and because of peer pressure; and casual sex as part of socializing.

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: This article discusses the challenges faced by most families in Botswana and the familial and social nets these families rely on to overcome the challenges. Both primary and secondary data were used to gather information. In-depth interviews were conducted with represenatives of various tribes to get their perspective on the topic. HIV/AIDS was found to be at the centre of all social, economic, moral, spiritual, and emotional interaction among family members. Its impact is challenging traditional thinking about family structures and family life and necessitating their redefinition. URI: http://hdl.handle.net/10311/543 Files in this item: 1

Abstract: Fault-plane solutions of an earthquake can provide information about the type of fault. We report on the calculation of the fault-plane solutions of the earthquake that occurred on the morning of 18 May 2001 and was felt in the southern parts of Botswana and the North West Province of South Africa. The fact that there were few seismic stations in the vicinity of these areas meant that standard programs such as FOCMEC would produce a large number of possible fault-plane solutions. In this study a semi-manual method of determining fault-plane solution was utilized to obtain the most likely solution from a SEISAN program. The results obtained from these two methods shows that the focal mechanism for this earthquake was normal faulting. The two methods used compliment each other. Other information obtained includes epicenter at coordinates (longitude 26.0E, latitude 25.6S), magnitude of about 4.6 ML and origin time of 9:14.10.52 UTC.

Abstract: Researchers and activists in Botswana have played an active role in the international campaign to alleviate women s subordinate position in economic development. Of late attention has shifted from 'women' to 'gender'. This shift has been premised on the need to provide a more holistic framework that focuses on relations between women and men, rather than on women exclusively. However, there are mounting concerns among academics and development practitioners that the gender debate has reached a stalemate in Botswana. The impasse is manifested in the perception that 'gender' and 'women' are used as synonyms in much gender discourse, research and activism. This paper argues that focusing on women and ostracising men makes the task of mainstreaming (or engendering) research and practice an unobtainable illusion. We propose new dimensions in gender discourses that will provide more balanced perspectives on both women and men. URI: http://hdl.handle.net/10311/901 Files in this item: 1

Abstract: Advantages of using Finite Element Method (FEM)in structural engineering practice are presented in this paper.A brief description of the method is given with the aim to illustrate the rich solid mathematical basis that makes its foundation.The paper then presents some guidelines on how to build a good model for Finite Element Analysis (FEA) purposes. The guideline emphasises the need for the analyst to have a clear understanding of the physical problem and of the behaviour of the elements he employs to carry out the analysis.A practical example presented in order to illustrate the type of analysis and results that can be obtained from a commercial FE software package. This example forms part of the research work that was carried out by the author.And finally, it is recommended that all practicing structural engineers must learn the basics of finite element method, and be equiped with some FE software packagess. Since it is the most commonly used and trusted method in the world of engineering today. In order to keep up with the rest of the world in engineering advancements, the author finds it vital to equip all engineers with the latest engineering software packages and to elevate continuing engineering education.

Abstract: Satellite imagery derived fire history data for the southern Okavango Delta, Botswana from 1989 to 2003 were used to analyse the temporal and spatial distribution of fires and to assess changes in fire activity. Maximum fire activity was encountered for 1997 with 24.1% of the study area burned. The annual extent of the burned area fluctuated considerably, but there appeared to be a regular oscillation apparently induced by floodplain fires. The main fire activity on drylands is in September at the end of the dry season, while most floodplains burn earlier in the year. Both burning of floodplains and drylands appear to peak prior to floods and rainfall-events, respectively. Areas with highest fire frequency were outlined and spatial analyses showed that fires on the drylands are largely due to burning of adjacent floodplains. The floodplains were therefore identified as the centres of fire activity, being the regions with the highest fire frequency and serving as source of fires spreading into drylands. Floodplains showed higher fire frequencies compared to drylands, but no increase in fire activity was detected over the study period for both floodplains and drylands. Description: The study was part of the project 'Fire regime and vegetation response in the Okavango Delta, Botswana' funded by the Volkswagen Foundation, Germany and carried out by the Chair of Vegetation Ecology, Technische Universitaet Muenchen, Germany in collaboration with the Harry Oppenheimer Okavango Research Center (HOORC, University of Botswana) and University of Pretoria, South Africa. Financial support was also given by Conservation International Botswana and the German Academic Exchange Service (DAAD). URI: http://hdl.handle.net/10311/151 Files in this item: 2

Abstract: The influence of wild fires on microbial community structure, soil organic matter, sulphur oxidising and nitrifying microbial populations in the floodplains of the Okavango Delta of Botswana was assessed. Microbial community structure was assessed by phospholipids ester-linked fatty acids (PLFA) quantification while microbial sulphur oxidisers were assessed by Most Probable Number (MPN). Community structure assessment showed that burning shifted the microbial community structure from single cellular bacteria being the dominant groups to filamentous fungi and actinomycetes being the most dominant groups. Generally burning increased the fungal component (18:2 w6) matrix from 3.40 to 8.35 while the actinomycetes and sulphur reducing bacterial (10 Me 16:0) component also increased from 1.02 to 1.70 mostly in the floodplains. Generally, the organic matter content declined with burning. However, the influence of burning on soil pH was non conclusive. Soil microbial biomass carbon increased slightly after the fire. The number of heterotrophic and nitrite-oxidizing and sulphur reducing bacteria increased. Overall, these results indicate that burning significantly alters the microbial community structure as large above ground losses of nutrients during and after burning often results in low quantities of nutrients released into the soil.

Abstract: From the roots of Bulbine frutescens, the first sulfated phenylanthraquinones were isolated, together with their known sulfate-free analogs. Their structures were elucidated by spectroscopic and chiroptical methods, by acid hydrolysis or by partial synthesis. The new compounds have the usual stereo-orientation at the biaryl axis (i.e., with the acetyl portion above the anthraquinone plane) except for sodium ent-knipholone 60-O-sulfate (and thus, also its hydrolysis product, ent-knipholone), which exhibit an opposite axial configuration. We also describe the first stereoanalysis of natural phenylanthraquinones, some of which were found to be not enantiomerically pure, some even nearracemic. We furthermore, report on the first X-ray structure analysis of a phenylanthraquinone, viz. 40-O-demethylknipholone. URI: http://hdl.handle.net/10311/246 Files in this item: 2

Abstract: This study compared the fitness of Black African early adolescents with and without mild mental retardation. Participants included 30 purposively selected early adolescent Black Africans with mild mental retardation aged 11-14 from three schools for children with mild mental retardation in Southern Botswana and 30 randomly selected early adolescents of similar ages without mental retardation. Participants were assessed on a number of standard fitness variables including the Rockport Walk Test. In general, when compared to participants without mental retardation, participants with mild mental retardation exhibited low levels of fitness. Based on study results, the Ministry of Education is called upon to urgently put in place policies and programs that would reverse the low level of fitness among adolescents with mild mental retardation.

Abstract: Effects of flooding on soil nitrogen (N), and asymbiotic nitrogen fixing bacterial (diazotroph) populations of the Okavango Delta were investigated. Diazotrophs from the rhizosphere of dominant annual and perennial grasses of the Okavango Delta were isolated on N-free composite media and identified applying morphological and biochemical criteria and Restriction Fragment Length Polymorphism (RFLP). Azotobacter species were found associated mostly with the grasses Andropogon guyanus and Vetevaria nigritiana (103CFU g–1 rhizosphere soil). Annual grasses such as Eragrostis inamoena, Setaria sphacelata as well as perennials showed insignificant populations (<101CFU g–1 soil). On the contrary, Azospirillum spp. was found associated with most of the grasses. Highest population densities (above 104MPN g–1 soil) were observed in rhizospheres of E. inamoena, Cympogon excavatus, Sporobolus acinifolis, Eragrostis lapila and Eragrostis rigidor and lowest population densities (below 102MPN g–1 soil) in rhizospheres of Andropogon guyanus and Panicum repens. Flooding increased the Azotobacter populations, while Azospirillum spp. populations were significantly reduced. Nitrogen-fixing sulphur reducers were observed in the rhizosphere of annuals (A. guyanus and P. repens) and only in perennials growing in flooded soils. No Beijerinckia species were found associated with any of the grasses. The highest soil nitrogen levels were detected in flooded soils (<0.20% N) while no N was detected in the rhizosphere soil of grasses growing in very dry soils (<5% moisture content). The results indicate that in the Okavango Delta, total soil nitrogen varies with flooding regime. With flooding, the diazotroph population shifts towards Azotobacter and Nfixing sulphur reducers while Azospirillum spp. are widespread in non-flooded soils. RFLP analysis of the 1 450bp amplicon using the restriction endonuclease Alu1, showed three different banding profiles, suggesting the occurrence of three different species of Azospirillum.

Abstract: The sale of herbal medicine, either as concoctions or single plant specimens, has become common in the streets and main shopping centres of major towns and cities in Botswana. A study was undertaken to collect information on the uses of medicinal plants sold by street vendors in Gaborone, Botswana during June 2008 to December 2008. The indigenous knowledge of the street vendors and the plants used for medicinal purposes were collected through questionnaire and personal interviews during field trips. The survey showed that the street vendors used 47 species of plants distributed in 45 genera belonging to 29 families to treat various diseases and health conditions. The documented medicinal plants were mostly used to cure skin sores, sexually transmitted diseases (STD) and asthma. In this study, the most dominat families are the Asteraceae and Fabaceae, each with 5 species and roots were most frequently used for the treatment of diseases accounting for 62% of the medicines sold. This study showed that many people in Botswana still continue to depend on medicinal plants for primary healthcare. URI: http://hdl.handle.net/10311/922 Files in this item: 1

Abstract: The fluorescence studies of coagulating protein extracted from Moringa oleifera seeds have been studied using steady-state intrinsic fluorescence. The fluorescence spectra are dominated by tryptophan emission and the emission peak maximum ( max = 343±2 nm) indicated that the tryptophan residue is not located in the hydrophobic core of the protein. Changes in solution pH affected the protein conformation as indicated by changes in the tryptophan fluorescence above pH 9 whereas the ionic strength had minimal effect. The exposure and environments of the tryptophan residue were determined using collisional quenchers. URI: http://hdl.handle.net/10311/323 Files in this item: 1
