Abstract:

East Coast fever (ECF) is an infectious tick-borne disease of cattle, caused by a protozoan parasite Theileria parva. It is a disease of major economic importance in Zambia as it is the main cause of cattle morbidity and mortality. Despite its economic importance, the epidemiology of ECF in Zambia is poorly understood, thereby making ECF prevention and control difficult. Further, there is limited published literature on this disease in Zambia, with little available research concentrating on Southern and Eastern provinces. Such literature is mostly based on serological techniques such as indirect fluorescent antibody test (IFAT) which have limited sensitivity and specificity. Thus, this study was conducted to determine the prevalence and associated risk factors of ECF in Copperbelt and Central provinces of Zambia. The study was cross-sectional in design. Multistage cluster sampling was used involving district, veterinary camp, herd and individual animals. The provinces and districts were selected based on their vast potential for livestock production and the previously reported incidence of ECF. From each district, two veterinary camps were randomly selected. From each camp, herds were randomly selected from which individual animals were randomly sampled. Samples were collected from Mpongwe and Masaiti districts (Copperbelt province) and Kapiri Mposhi and Chibombo districts (Central province). Samples were examined for the presence of schizonts on Giemsa stained lymph smears. The lymph smear examinations revealed that 6.4% (95%, CI=4.9-7.9) of the samples were positive for T. parva schizonts. In Central province, the overall prevalence was 6.7% (95%, CI=4.0-8.2), while in the Copperbelt province it was 6.1% (95%, CI=4.0-8.2). Among the districts in these provinces, Kapiri Mposhi did not record any schizont positive cattle, while Masaiti recorded 2.4% (95%, CI=0.5-4.3). Mpongwe had a prevalence of 9.7% (95%, CI=6.0-13.4) and Chibombo had the highest prevalence at 13.6% (95%, CI=9.4-17.9). Risk factors that were identified to be associated with ECF were the district, frequency of veterinary service provision, tick control frequency, age and previous experience of ECF. The results indicate that ECF is prevalent in Copperbelt and Central provinces and hindering livestock production. There is hence the need for concerted efforts to control ticks and prevent ECF transmission through farmer sensitization, routine, regular, mandatory and supervised dipping and spraying of cattle and stringent livestock movement control.

Abstract:

Purpose: The purpose of this study was to investigate factors which affect motivation of librarians in three selected Universities in Zambia namely; Mulungushi University, Copperbelt University and Nkrumah University. The objectives of this study were to determine the extent to which librarians are motivated in their work, to find out factors that influence motivation among librarians in the selected university libraries in the Central and Copperbelt provinces of Zambia, to assess the impact of communication and staff development on staff motivation in the selected university libraries in the Central and Copperbelt provinces of Zambia and to propose measures aimed at contributing towards job motivation among librarians from the selected university libraries in the Central and Copperbelt province of Zambia. Methodology: The study was a survey by design targeting library staff such as sub-librarians, assistant librarians, senior library assistants as well as library assistants. A sample of 103 respondents was selected using purposive sampling. The survey combined qualitative and quantitative methods; qualitative data obtained from interviews using administered and self-administered questionnaires and interview technique results were analysed by coding and regrouping similar themes using constant comparative techniques. Quantitative data was collected and presented statistically in form of percentages and graphs. Findings: Study indicated various factors which can motivate librarians to do more work such as responsibilities including, good salary, promotion and work achievement. Unique Contributions to Theory Practice and Policy: The uniqueness of this research is that the findings will be used as reference by future researchers on this or related topics and this will help manager to put in place measures which will help motivate library staff. Hence this will lead to attainment of hard work among staff and delivery of quality services to clients.

Abstract:

Bemba tonology has been described with respect to two prominent claims: H tone local spreading is binary, and is blocked by the OCP. These claims are based on Bemba, as spoken in Northern Zambia. This paper examines these two claims with respect to contemporary Bemba as it is spoken today in the Copperbelt province of Zambia. This paper shows that in Copperbelt Bemba (CB), these two aspects of H tone spreading are markedly different. In CB, local spreading is ternary, not binary, and a H will undergo binary spreading even if it causes an OCP violation. Ternary spread will be shown to follow from two rules: High Tone Doubling and Secondary High Doubling motivated by different constraints within CB tonology. In addition to documenting and describing the behavior of high tone in CB, a comparison to other cases of ternary spreading is also made.

Abstract:

Background Voluntary Medical Male Circumcision (VMMC) is a key intervention in HIV/AIDS. Improving VMMC program uptake in Zambia requires careful monitoring of adverse events (AE) to inform program quality and safety. We investigate the prevalence of VMMC AE and their associated factors among adult males in Ndola, Copperbelt Province, Zambia. Methods We performed a cross-sectional study using secondary clinical data collected in 2015 using two validated World Health Organisation/Ministry of Health reporting forms. We reviewed demographics and VMMC surgical details from 391 randomly sampled adult males aged ≥18 years at Ndola Teaching Hospital, a specialised VMMC fixed site in Zambia. Non-parametric tests (Fisher’s exact test or Chi-square depending on assumptions being met) and logistic regression were conducted to determine the relationships between associated factors and VMMC AE. Results The overall VMMC AE prevalence was 3.1% (95% CI 1.60%– 5.30%) and most AEs occurred postoperatively. In decreasing order, the commonly reported VMMC AE included; bleeding (47.1%), swelling (29.4%), haematoma (17.6%), and delayed wound healing (5.9%). There was an inversely proportional relationship between VMMC volume (as measured by the number of surgeries conducted per VMMC provider) and AEs. Compared to the highest VMMC volume of 63.2% (247/391) as reference, as VMMC volume reduced to 35.0% (137/391) and then 1.8% (7/391), the likelihood of AEs increased by five times (aOR 5.08; 95% CI 1.33–19.49; p = 0.018) and then sixteen times (aOR 16.13; 95% CI 1.42–183.30; p = 0.025) respectively. Conclusions Our study found a low prevalence of VMMC AEs in Ndola city, Copperbelt Province of Zambia guaranteeing the safety of the VMMC program. We recommend more surgically proficient staff to continue rendering this service. There is a need to explore other high priority national/regional areas of VMMC program safety/quality, such as adherence to follow-up visits.

Abstract:

In Zambia, poultry is a rapidly increasing sector contributing 4.8% of the Agricultural Gross Domestic Product (GDP), thus providing a significant income-generating activity. Worldwide, poultry is a major reservoir of Salmonella with an increasing incidence of extended-spectrum beta-lactamase (ESBL) producing strains. ESBLs are enzymes produced by bacteria and are capable of inactivating a wide range of beta-lactam antibiotics. Salmonella enterica serovars Enteritidis and Typhimurium are the most important foodborne serotypes in many countries, infecting both humans and animals and are transmitted to humans through the food supply chain. CTX-M ESBLs have been described in Salmonella Typhimurium isolates with resistant genes located on transferable plasmids. This study aimed to detect S. Typhimurium, their antimicrobial resistance, and CTX-M-type ESBL Producing strains in commercial poultry farms in Copperbelt Province, Zambia. Five districts were considered for this study, where one poultry farm per district was randomly selected for sampling. An overall number of 384 fecal samples were analyzed using microbiological and molecular methods. S. Typhimurium was detected at 17.7% (CI: 14.2%-21.8%) in commercial poultry farms in Copperbelt Province, of which 12.8% (CI: 9.8%-16.5%) were found harboring the CTX-M-Type ESBL genes. S. Typhimurium isolates showed 88.2% resistance to at least one antimicrobial compound. All the isolates showed 100% resistance to tetracycline, followed by ampicillin and amoxicillin at 91.2%. These isolates also showed 58.8% resistance to cefotaxime and 54.4% to ceftazidime. Detection of CTX-M ESBL producing Salmonella Typhimurium suggests the contamination of chicken food chain at farm level and calls for public health protection measures.

Abstract:

AbstractPyrometallurgical slags from three Cu-Co smelters (Nkana, Mufulira, Chambishi) in the Copperbelt Province, Zambia, were studied from mineralogical and chemical points of view. The slags were enriched in metals and metalloids, mainly Cu (up to 35 wt.%), Co (up to 2.4 wt.%) and As (up to 3650 ppm). The following primary phases were observed in slags: Ca-Fe silicates (clinopyroxene, olivine) and leucite, oxides (spinel-series phases), ubiquitous silicate glass and sulphide/metallic droplets of various sizes. The presence of glass and skeletal/dendritic crystal shapes indicated rapid cooling of the slag melt. Copper and cobalt were found in low concentrations in the majority of silicates (olivine, clinopyroxene) and oxides, substituting for Fe in their structures (up to 7.15 wt.% CoO in olivine, 4.11 wt.% CuO in spinel). Similarly, up to 0.91 wt.% CoO and 6.90 wt.% CuO were observed in the interstitial glass. Nevertheless, the main carriers of these metals in the slags studied were Cu sulphides (digenite, chalcocite, bornite, chalcopyrite), Co-Fe sulphides (cobaltpentlandite), Co-bearing intermetallic phases ((Fe,Co)2As) and alloys. Weathering features corresponding to the presence of secondary metal-bearing phases, such as malachite (Cu2(CO3)(OH)2), brochantite (Cu4SO4(OH)6) and sphaerocobaltite (CoCO3), were observed on the slag surfaces. They indicate that the slags studied are reactive on contact with water/atmosphere and that their environmental stability and release of potentially harmful metals and metalloids must be evaluated further.

Abstract:

Abstract The Central African Copperbelt (CACB) is Earth’s largest repository of sediment-hosted copper and cobalt. The criticality of these elements in battery technology and electricity transmission establishes them as fundamental components of the carbon-free energy revolution, yet the nature and origin of the hydrothermal fluids responsible for ore formation in the CACB remain controversial. Here, we present microthermometric, scanning electron microscopy and laser ablation–inductively coupled plasma–mass spectrometry analyses of fluid inclusions from the Nkana-Mindola deposits in Zambia. We find that base metal concentrations vary by one to two orders of magnitude between “barren” and “ore” fluids, with concomitant distinctions in major salt chemistry. Primary fluid inclusions, hosted by pre- to synkinematic mineralized quartz veins, are characterized by high homogenization temperatures (∼200–300 °C) and salinities, with K/Na &gt;0.8 and elevated metal concentrations (102 to 103 ppm Cu and Co). Conversely, barren, postkinematic vein quartz contains lower homogenization temperature (∼110–210 °C) and lower-salinity primary inclusions, characterized by K/Na &lt;0.8 with low metal contents (&lt;102 ppm Cu and Co). We propose a model in which high-temperature, sulfate-deficient, metalliferous, potassic residual brines, formed during advanced evaporation of CaCl2-rich, mid-Neoproterozoic seawater, were responsible for ore formation. During basin closure, lower-temperature, halite-undersaturated fluids interacted with evaporites and formed structurally controlled, sodic metasomatism. Reconciliation of these fluid chemistries and base metal concentrations with reported alteration assemblages from a majority of Zambian Copperbelt deposits suggests highly evolved, residual brines were critical to the formation of this unique metallogenic province.

Abstract:

The need to protect forest resources from unsustainable, yet rational, human actions has attracted global attention. This is because smallholder dependence on forests can degrade forest resources and cause deforestation. While efforts to understand forest programmes and motivations to protect forests have increased in recent decades, there remains a limited understanding of household factors affecting participation in forest support programmes, especially in the context of high-pressure areas, such as the Miombo woodlands. This study was conducted in the North-Western, Copperbelt and Eastern Province of Zambia. In each province, we selected landscapes consisting of protected and non-protected forest areas. We administered structured interviews to 1123 households and used logistic regression to estimate determinants of participation. We found that better education, landholding size, increased share of forest income, cash crops and non-farm income, and access to forests and markets have a negative impact on participation in forest support programmes. Being located in landscapes with protected areas was positively associated with participation. We suggest that, in order to increase participation, forest programmes should focus on households with low levels of education, limited livelihood opportunities, and poor access to markets. Besides, programmes should provide incentives, including support for farm inputs and at the same time encourage reforestation and agroforestry methods.

Abstract:

Many scientific research projects carried out in developing countries gather data and fail to return any summary of the findings to the community that provided the data. Residents from communities experiencing water issues are therefore deprived of effective participation in the use of findings, since communities might be seen as only a source of data. Indigenous writers have revealed the injustice of this reality and have suggested that this is typical of colonial or ‘colonising’ research methods. It is concerning because accessing research knowledge encourages communities to examine their issues and empowers them to formulate solutions. Inspired by decolonising methodologies, we explored different ‘decolonising’ approaches to returning research findings to participant communities using the results of a recent water research project conducted in Ndola, Copperbelt Province, Zambia. In this case study, we describe participant communities experience regarding access to research findings and conclude that face-to-face discussion is the preferred approach to returning water research findings in Ndola.

Abstract:

In many developing countries, the effect of climate change on agriculture is evaluated with reference to small scale farmers, mainly under low input systems. As a result, literature on climate variability and its effect on high input farming systems are scanty. We evaluated the impact of climatic variability on maize and soybean yield under a high input management system. The objectives of the study were to: (i) assess rainfall and temeperature variability at a high input farm (ii) evaluate the effect of rainfall and temperature on maize and soybean yield under high input management system. (iii) assess the impact of El Ni&ntilde;o and La Ni&ntilde;a on maize and soybean yield. Data for rainfall and temperature was obtained from Zambia Meteorological Department which was complimented by records from the weather station located at the study site. Yield data for both maize and soybean was provided by ZAMBEEF farm. The analysis covered 32 years from 1980 to 2012. Time series plot was used to investigate the trend in minimum and maximum temperature and seasonal rainfall. Correlations were done in SPSS to establish the strength and direction of association between climatic variables (temperature and seasonal rainfall) and maize and soybean yield. Multiple Regression in SPSS was then used to analyze variation in maize and soybean yield due to climatic variables. Results revealed that minimum temperature had an increasing linear trend of 0.3&deg;C to 0.5 per decade while maximum temperature showed an increasing linear trend of 0.2&deg;C to 0.3&deg;C per decade. On the other hand, seasonal rainfall was variable with over the period studied. The variations in maize and soybean yield explained by seasonal rainfall and temperature was not significant with only 17.2% and 20.1% of the variation explained, respectively. Although there was no significant impact of both El Ni&ntilde;o and La Ni&ntilde;o on the yields of both crops, regression analysis revealed a negative relationship between El Ni&ntilde;o and soybean yield and a positive relationship with maize yield and a positive relationship was revealed between La Ni&ntilde;a and maize and soybean yields.

Abstract:

This article aims to identify and discuss the existence and strengthening of a child-centred teaching discourse in Zambian kindergartens. The article is based on the understanding that the teacher-directed approach to teaching is a historically based hegemonic discourse within Zambian kindergartens. This means that the teacher-directed teaching discourse dominates thinking in many ways and is translated into institutional arrangements (Hajer, 1995, in Svarstad, 2005, p. 243). Several studies have pointed to the challenges posed by the teacher-directed teaching discourse in kindergartens in Sub-Saharan Africa as a hindrance of pedagogical quality in such institutions, pointing to a child-centred teaching discourse as an important path towards development (EFA, 2015, p. 208, Temba, 2014, p. 110; Mwaura et al., 2008; 2011). This article includes a positive discourse analysis of the Zambian Education Curriculum Framework[1] and a small-scale qualitative study, based on observations from four classrooms in four kindergartens in the Copperbelt province of Zambia. The article focuses on conducting a positive discourse analysis of the elements of child-centred teaching discourse observed in one of the four classrooms. The findings point to the existence of a child-centred teaching discourse in the Zambian Education Curriculum Framework. However, only one of the four Zambian kindergarten teachers seemed to implement teaching practices that could be identified as a child-centred teaching discourse. he elements of a child-centred teaching discourse identified through the positive discourse analysis were: the kindergarten teachers’ professional decisions, good interaction with children, use of a variety of materials, and children’s participation. The findings are discussed in light of the Zambian Education Curriculum Framework as well as theoretical perspectives on child-centred teaching discourse, argumentation theory and children’s right to participation. Finally, the article includes a critical discussion of how the findings may strengthen a child-centred teaching discourse in Zambian kindergartens.

Abstract:

AbstractObjectiveTo investigate trends in child malnutrition in six countries in southern Africa, in relation to the HIV epidemic and drought in crop years 2001/2 and 2002/3.DesignEpidemiological analysis of sub-national and national surveys with related data.SettingData from Lesotho, Malawi, Mozambique, Swaziland, Zambia and Zimbabwe, compiled and analysed under UNICEF auspices.SubjectsSecondary data: children 0–5 years for weight-for-age; HIV prevalence data from various sources especially antenatal clinic surveillance.ResultsChild nutritional status as measured by prevalence of underweight deteriorated from 2001 onwards in all countries except Lesotho, with very substantial increases in some provinces/districts (e.g. from 5 to 20% in Maputo (Mozambique, 1997–2002), 17 to 32% in Copperbelt (Zambia, 1999–2001/2) and 11 to 26% in Midlands province (Zimbabwe, 1999–2002)). Greater deterioration in underweight occurred in better-off areas. Areas with higher HIV/AIDS prevalences had (so far) lower malnutrition rates (and infant mortality rates), presumably because more modern areas – with greater reliance on trade and wage employment – have more HIV/AIDS. Areas with higher HIV/AIDS showed more deterioration in child nutrition. A significant area-level interaction was found of HIV/AIDS with the drought period, associated with particularly rapid deterioration in nutritional status.ConclusionsFirst, the most vulnerable may be households in more modern areas, nearer towns, to whom resources need to be directed. Second, the causes of this vulnerability need to be investigated. Third, HIV/AIDS amplifies the effect of drought on nutrition, so rapid and effective response will be crucial if drought strikes again. Fourth, expanded nutritional surveillance is now needed to monitor and respond to deteriorating trends. Finally, with or without drought, new means are needed of bringing help, comfort and assistance to the child population.

Abstract:

The influence of imported material, technology and methods has put pressure on most traditional architectural systems to modernize. This influence to modernize is transmitted through various mechanisms. This paper argues that there are a number of aspects to vernacular architecture that would be lost through this conversion process to modern materials, technology and methods. Through the examination of vernacular architecture among the Lamba people of Senior Chief Mushili’s chiefdom, the study found that there are cultural, environmental and aesthetical aspects in vernacular architecture that are poorly understood in the process of modernization. Data for this research were collected through an ethnographical approach with occasional in-depth interviews with senior members of the Royal establishment and the community. Thus, the data were mainly qualitative.

Abstract:

Abstract. An estimated variogram of a soil property can be used to support a rational choice of sampling intensity for geostatistical mapping. However, it is known that estimated variograms are subject to uncertainty. In this paper we address two practical questions. First, how can we make a robust decision on sampling intensity, given the uncertainty in the variogram? Second, what are the costs incurred in terms of oversampling because of uncertainty in the variogram model used to plan sampling? To achieve this we show how samples of the posterior distribution of variogram parameters, from a computational Bayesian analysis, can be used to characterize the effects of variogram parameter uncertainty on sampling decisions. We show how one can select a sample intensity so that a target value of the kriging variance is not exceeded with some specified probability. This will lead to oversampling, relative to the sampling intensity that would be specified if there were no uncertainty in the variogram parameters. One can estimate the magnitude of this oversampling by treating the tolerable grid spacing for the final sample as a random variable, given the target kriging variance and the posterior sample values. We illustrate these concepts with some data on total uranium content in a relatively sparse sample of soil from agricultural land near mine tailings in the Copperbelt Province of Zambia.

Abstract:

Decision tree (DT) algorithms are important non-parametric tools used for land cover classification. While different DTs have been applied to Landsat land cover classification, their individual classification accuracies and performance have not been compared, especially on their effectiveness to produce accurate thresholds for developing rulesets for object-based land cover classification. Here, the focus was on comparing the performance of five DT algorithms: Tree, C5.0, Rpart, Ipred, and Party. These DT algorithms were used to classify ten land cover classes using Landsat 8 images on the Copperbelt Province of Zambia. Classification was done using object-based image analysis (OBIA) through the development of rulesets with thresholds defined by the DTs. The performance of the DT algorithms was assessed based on: (1) DT accuracy through cross-validation; (2) land cover classification accuracy of thematic maps; and (3) other structure properties such as the sizes of the tree diagrams and variable selection abilities. The results indicate that only the rulesets developed from DT algorithms with simple structures and a minimum number of variables produced high land cover classification accuracies (overall accuracy > 88%). Thus, algorithms such as Tree and Rpart produced higher classification results as compared to C5.0 and Party DT algorithms, which involve many variables in classification. This high accuracy has been attributed to the ability to minimize overfitting and the capacity to handle noise in the data during training by the Tree and Rpart DTs. The study produced new insights on the formal selection of DT algorithms for OBIA ruleset development. Therefore, the Tree and Rpart algorithms could be used for developing rulesets because they produce high land cover classification accuracies and have simple structures. As an avenue of future studies, the performance of DT algorithms can be compared with contemporary machine-learning classifiers (e.g., Random Forest and Support Vector Machine).

Abstract:

Purpose Productivity and production risks affect the use of agricultural production practices and inputs, particularly in developing countries. This paper aims to investigate the effects of adopting drought-tolerant maize varieties (DTMVs) on farm productivity, yield variance and downside risk exposure of maize growing households of Zambia. Design/methodology/approach The study uses household survey data collected from 11 maize producing districts of Eastern, Southern and Copperbelt provinces of Zambia using a structured questionnaire. The Antle’s flexible moment-based approach was used in specifying, estimating and testing a stochastic production function. The study further applied an endogenous switching regression model to control for both observable and unobservable sources of bias. Findings The study revealed that DTMV adoption increases maize yield by 15 per cent and reduces the risk of crop failure: reducing yield variance by 38 per cent and exposure to downside risk by 36 per cent. Originality/value This study establishes the benefits of DTMV adoption in Zambia with regards to productivity, yield stability and downside risk in the face of climate change. Results from this study underscore the need for more concerted efforts to scale-out DTMVs for both maize productivity enhancement and for risk mitigation against weather shocks.

Abstract:

Background: As donor contributions for HIV/AIDS stagnate globally, national governments must seek ways to improve use of existing resources through interventions to drive efficiency at the facility level. But program managers lack routinely available information on unit expenditures at points of care, and higher-level planners are unable to assess how resources are used throughout the health system. Thus, managers cannot measure current levels of technical efficiency, and are unable to evaluate effectiveness of interventions to increase technical efficiency. Methods: FHI 360 developed the Routine Efficiency Monitoring System (REMS), a relational database that leverages existing budget, expenditure and output data to produce quarterly site-level estimates of unit expenditure per service. Along with the Government of the Republic of Zambia (GRZ) and implementation partner Avencion, we configured REMS to measure technical efficiency of Ministry of Health resources used to deliver HIV/AIDS services in 326 facilities in 17 high-priority districts in Copperbelt and Central Provinces. REMS allocation algorithms were developed through facility assessments and key informant interviews with MoH staff. Existing IFMIS and DHIS-2 data streams provide recurring flows of expenditure and output data needed to estimate service-specific unit expenditures. Trained users access REMS output through user-friendly dashboards delivered through a web-based application. Results: District health management teams are using REMS to identify “outlier” facilities to test performance improvement interventions. Provincial and national planners are using REMS to seek savings and ensure that resources are directed to geographic and programmatic areas with highest need. REMS can support reimbursement for social health insurance and provide time-series data on facility-level costs for modeling purposes. Conclusions: REMS gives managers and planners substantially-improved data on how programs transform resources into services. The GRZ is seeking funding to expand REMS nationally, covering all major disease areas. Improved technical efficiency supports the goal of a sustainable HIV/AIDS response.
