Using a geographical information system to plan a malaria control programme in South Africa
Booman Marlize,Durrheim Dave N.,La Grange Kobus,Martin Carrin
Bulletin of the World Health Organization , 2000,
Abstract: INTRODUCTION: Sustainable control of malaria in sub-Saharan Africa is jeopardized by dwindling public health resources resulting from competing health priorities that include an overwhelming acquired immunodeficiency syndrome (AIDS) epidemic. In Mpumalanga province, South Africa, rational planning has historically been hampered by a case surveillance system for malaria that only provided estimates of risk at the magisterial district level (a subdivision of a province). METHODS: To better map control programme activities to their geographical location, the malaria notification system was overhauled and a geographical information system implemented. The introduction of a simplified notification form used only for malaria and a carefully monitored notification system provided the good quality data necessary to support an effective geographical information system. RESULTS: The geographical information system displays data on malaria cases at a village or town level and has proved valuable in stratifying malaria risk within those magisterial districts at highest risk, Barberton and Nkomazi. The conspicuous west-to-east gradient, in which the risk rises sharply towards the Mozambican border (relative risk = 4.12, 95% confidence interval = 3.88-4.46 when the malaria risk within 5 km of the border was compared with the remaining areas in these two districts), allowed development of a targeted approach to control. DISCUSSION: The geographical information system for malaria was enormously valuable in enabling malaria risk at town and village level to be shown. Matching malaria control measures to specific strata of endemic malaria has provided the opportunity for more efficient malaria control in Mpumalanga province.

Abstract: Successful development and application of a computerised spraying operations management system in Mpumalanga Province, South Africa during 1998 resulted in its adaptation and introduction in neighbouring Maputo Province, southern Mozambique during 2000. The structure and components of this computerised management system are described, and its' operational benefit in southern Mozambique, where community-based spray operators apply intradomiciliary insecticide, are reviewed.The computerised management system allowed malaria programme management and field supervisors to monitor spraying coverage, insecticide consumption and application rates on an ongoing basis. The system supported a successful transition to community-based spraying, while assuring correct insecticide application and spraying completion according to schedule.In 1946, South Africa introduced intradomiciliary spraying with residual insecticides, DDT (dichlorodiphenyltrichloroethane) and BHC (Benzene hexachloride), to kill indoor-resting vector mosquitoes and thereby control malaria [1]. This resulted in a 75 percent reduction in the geographic extent of the malaria-affected area, with malaria occurrence limited to summer epidemics in the low-lying northern and eastern border areas with Botswana, Zimbabwe and Mozambique [2,3]. Similar malaria control programmes were initiated in other southern African countries. In Mozambique, spraying operations for malaria control collapsed during the 1970s due to the protracted civil war with a resulting high burden of endemic malaria throughout the country [4].Recently there has been a resurgence of malaria in southern Africa, attributed to a number of factors, including parasite drug-resistance, mosquito insecticide-resistance, climate changes and large-scale population migration [3,5]. The HIV/AIDS epidemic has resulted in a simultaneous dwindling of resources available for public health programmes, thus placing an onus on programme managers to ensure optimal effic

KNOWLEDGE MANAGEMENT PRINCIPLES
Marlize Breedt,Antonie Van Rensburg
South African Journal of Industrial Engineering , 2012,
Abstract: ENGLISH ABSTRACT: Business drivers such as digitisation, globalisation, customer intimacy and the emergence of the Information Age initiate the need to manage the organisation's knowledge asset. Knowledge management aims at leveraging this explicit and tacit knowledge asset to the collective benefit of the organisation by developing an infrastructure to facilitate the knowledge process and by making information readily available. The implementation of such an initiative requires integration of the strategic, process, human resource, and technology architecture components as the company's competitive advantage depends on the quality of the organisation's knowledge asset and successful exploitation of it. AFRIKAANSE OPSOMMING: Veranderingsdrywers soos digitalisering, globalisering, klienteverhoudings en die ontstaan van die inligtingsera inisieer die behoefte om organisasiekennishulpbronne te bestuur. Kennisbestuur het ten doel om die eksplisiete en nie-eksplisiete kennishulpbron tot die gesamentlike voordeel van die organisasie aan te wend deur 'n infrastruktuur daar te stel om die kennisproses te fasiliteer en inligting beskikbaar te stel. Die implementering van 'n kennisbestuursinisiatief vereis integrasie van die strategiese-, proses-, menslikehulpbron-, en tegnologieargitektuur komponente ten einde die kompeterende voordeel van die organisasie te behou. Onderliggend tot die sukses is die vermoe en kwaliteit van die organisasie se kennishulpbronne.

Abstract: the transition to the xxi century has deeply changed relationships within society. education is part of such process and, thus, the relationship between the process of unification of europe itself and of its higher education is emblematic of such perception. this paper aims to bring about elements to understand the bologna process; analyzing aspects of its implementation; seeking for links between its characteristics and the goals and reasoning underlying that process; and discuss likely impacts upon the brazilian context. our analysis indicates that as europe aims to establish international partnerships to widen the scope of options for its higher education, one can assume that the agenda to be proposed tends to be screened by european interests. that, in its turn, requires some discussion and negotiation that foregrounds the notions of otherness and diversity, with the university fully performing its condition of privileged locus for critical, propositional and prospective analysis.
The Effect of Fear Appeal HIV-AIDS Social Marketing on Behaviour: Evaluating the Importance of Market Segmentation

Theoretical and Applied Economics , 2010,
Abstract: The increase in various social problems has caused practitioners to review fear appeals in order to influence behaviour. The Aids pandemic is a major concern and some advertising campaigns do not seem to be producing the expected results. This study used structural equation modelling to investigate whether the use of fear increases the likelihood of adopting appropriate behaviour pertaining to HIV/Aids prevention. Fear, attitude towards the advertisements, severity, susceptibility and efficacy were examined to ascertain the influence of fear appeals on a specific market segment. The findings of this paper indicate a relationship among susceptibility, fear, attitude and behavioural intent.

Abstract: Sweetpotato is a major staple food in the world. It is a good source of carbohydrates, vitamin A, vitamin C and protein. The maximum production potential of the crop is being hampered by severe drought which ravages most parts of Africa. The main aim of this study therefore was to screen accessions of sweetpotato for drought tolerance in a quick screening method, followed by field screening with a view to identify accessions that can perform well under water stress conditions. Fifty sweetpotato accessions consisting of cultivars and breeding lines collected from the ARC-VOPI gene bank were planted for drought screening in the glass house for six weeks during which water was withheld to induce stress. Observations were made on number of dead plants and days to wilting point. The results were analyzed and 12 best performing accessions were selected for field trials. The field trial was carried out in Lwamondo, Limpopo province, a drought prone area in South Africa, under rain-fed conditions. The best performing accessions were Zapallo, Tacna, Ejumula, 2004-9-2 and Ndou.
A moderate increase in ambient temperature modulates the Atlantic cod (Gadus morhua) spleen transcriptome response to intraperitoneal viral mimic injection

Abstract: Background Atlantic cod (Gadus morhua) reared in sea-cages can experience large variations in temperature, and these have been shown to affect their immune function. We used the new 20K Atlantic cod microarray to investigate how a water temperature change which, simulates that seen in Newfoundland during the spring-summer (i.e. from 10°C to 16°C, 1°C increase every 5 days) impacted the cod spleen transcriptome response to the intraperitoneal injection of a viral mimic (polyriboinosinic polyribocytidylic acid, pIC). Results The temperature regime alone did not cause any significant increases in plasma cortisol levels and only minor changes in spleen gene transcription. However, it had a considerable impact on the fish spleen transcriptome response to pIC [290 and 339 significantly differentially expressed genes between 16°C and 10°C at 6 and 24 hours post-injection (HPI), respectively]. Seventeen microarray-identified transcripts were selected for QPCR validation based on immune-relevant functional annotations. Fifteen of these transcripts (i.e. 88%), including DHX58, STAT1, IRF7, ISG15, RSAD2 and IκBα, were shown by QPCR to be significantly induced by pIC. Conclusions The temperature increase appeared to accelerate the spleen immune transcriptome response to pIC. We found 41 and 999 genes differentially expressed between fish injected with PBS vs. pIC at 10°C and sampled at 6HPI and 24HPI, respectively. In contrast, there were 656 and 246 genes differentially expressed between fish injected with PBS vs. pIC at 16°C and sampled at 6HPI and 24HPI, respectively. Our results indicate that the modulation of mRNA expression of genes belonging to the NF-κB and type I interferon signal transduction pathways may play a role in controlling temperature-induced changes in the spleen’s transcript expression response to pIC. Moreover, interferon effector genes such as ISG15 and RSAD2 were differentially expressed between fish injected with pIC at 10°C vs. 16°C at 6HPI. These results substantially increase our understanding of the genes and molecular pathways involved in the negative impacts of elevated ambient temperature on fish health, and may also be valuable to our understanding of how accelerated global climate change could impact cold-water marine finfish species.

Abstract: Background Emerging information technologies present new opportunities to reduce the burden of malaria, dengue and other infectious diseases. For example, use of a data management system software package can help disease control programs to better manage and analyze their data, and thus enhances their ability to carry out continuous surveillance, monitor interventions and evaluate control program performance. Methods and Findings We describe a novel multi-disease data management system platform (hereinafter referred to as the system) with current capacity for dengue and malaria that supports data entry, storage and query. It also allows for production of maps and both standardized and customized reports. The system is comprised exclusively of software components that can be distributed without the user incurring licensing costs. It was designed to maximize the ability of the user to adapt the system to local conditions without involvement of software developers. Key points of system adaptability include 1) customizable functionality content by disease, 2) configurable roles and permissions, 3) customizable user interfaces and display labels and 4) configurable information trees including a geographical entity tree and a term tree. The system includes significant portions of functionality that is entirely or in large part re-used across diseases, which provides an economy of scope as new diseases downstream are added to the system at decreased cost. Conclusions We have developed a system with great potential for aiding disease control programs in their task to reduce the burden of dengue and malaria, including the implementation of integrated vector management programs. Next steps include evaluations of operational implementations of the current system with capacity for dengue and malaria, and the inclusion in the system platform of other important vector-borne diseases.
