Conceptual graph-based knowledge representation for supporting reasoning in African traditional medicine

Although African patients use both conventional or modern and traditional healthcare simultaneously, it has been proven that 80% of people rely on African traditional medicine (ATM). ATM includes medical activities stemming from practices, customs and traditions which were integral to the distinctive African cultures. It is based mainly on the oral transfer of knowledge, with the risk of losing critical knowledge. Moreover, practices differ according to the regions and the availability of medicinal plants. Therefore, it is necessary to compile tacit, disseminated and complex knowledge from various Tradi-Practitioners (TP) in order to determine interesting patterns for treating a given disease. Knowledge engineering methods for traditional medicine are useful to model suitably complex information needs, formalize knowledge of domain experts and highlight the effective practices for their integration to conventional medicine. The work described in this paper presents an approach which addresses two issues. First it aims at proposing a formal representation model of ATM knowledge and practices to facilitate their sharing and reusing. Then, it aims at providing a visual reasoning mechanism for selecting best available procedures and medicinal plants to treat diseases. The approach is based on the use of the Delphi method for capturing knowledge from various experts which necessitate reaching a consensus. Conceptual graph formalism is used to model ATM knowledge with visual reasoning capabilities and processes. The nested conceptual graphs are used to visually express the semantic meaning of Computational Tree Logic (CTL) constructs that are useful for formal specification of temporal properties of ATM domain knowledge. Our approach presents the advantage of mitigating knowledge loss with conceptual development assistance to improve the quality of ATM care (medical diagnosis and therapeutics), but also patient safety (drug monitoring)

An Interrogation of Diarrhoea Concept among Yoruba Women in Ibadan Metropolis, Nigeria

This paper explores and simultaneously interrogates the emic perspective of childhood diarrhoea among Yoruba women living in Ibadan metropolis, Nigeria. The data was derived from in-depth interviews and focus group discussions conducted with women and other significant members of households who were health givers to children below five years of age. Two major concepts that are associated with childhood diarrhoea, owó ọmọ and ọwọ́́ iỳá, are analyzed within a phenomenological framework of African philosophy that challenges orthodox discourse of human health and life experience. The paper draws the attention of international health organizations collaborating with the Nigerian government in reducing child mortality associated with diarrhoea the inherent danger in ignoring folks’ beliefs and concepts. The paper concludes that it is only in recognition of cultural cosmologies that local people can be actively involved in designing improvement strategies and carrying out hygienic education sensitively

Infectious Disease Ontology

Technological developments have resulted in tremendous increases in the volume and diversity of the data and information that must be processed in the course of biomedical and clinical research and practice. Researchers are at the same time under ever greater pressure to share data and to take steps to ensure that data resources are interoperable. The use of ontologies to annotate data has proven successful in supporting these goals and in providing new possibilities for the automated processing of data and information. In this chapter, we describe different types of vocabulary resources and emphasize those features of formal ontologies that make them most useful for computational applications. We describe current uses of ontologies and discuss future goals for ontology-based computing, focusing on its use in the field of infectious diseases. We review the largest and most widely used vocabulary resources relevant to the study of infectious diseases and conclude with a description of the Infectious Disease Ontology (IDO) suite of interoperable ontology modules that together cover the entire infectious disease domain

A paradigmatic map of professional education research

This article maps out research in professional education with reference to a threefold typology of paradigms i.e. the positivist, interpretivist and critical paradigms. The rationale for such an endeavour is fourfold. First, it directs attention to the neglected territory of methodology which is essential for researcher reflexivity. Second, it shows that most research in social work education has been situated within the positivist or interpretivist paradigms, and the relative dearth of studies in the critical paradigm raises important questions about anti-oppressive practice in research. Third, a comparison of studies in different spheres of professional education indicates that research into social work education has often not been as rich or robust as research into medicine or teaching, and this deserves further reflection. Finally, there is a practical rationale – although this exercise casts doubt upon our current capacity to develop evidence-based educational reforms, it should also signpost fruitful avenues for future research

Indigenous African Leadership: Key differences from Anglo-centric thinking and writings

The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.This article draws on historical explorers’ accounts, ethnography and organisational approaches to examine practices, discourses and perceptions of leadership in 12 prototypical indigenous communities in West and Central Africa. By so doing, it highlights how leadership meanings from this context differ from Anglo-centric thinking and writings. Key to this contribution is an unravelling of ways in which historical cultural hegemonies impose particular discursive formations, constructed practices and mind-programming in a non-Anglo-Saxon socio-cultural context. Dramaturgical power arrangement, lucid role substitution and the notion of leadership as nonhuman emerge as dominant themes in the analysis. Also, featuring significantly are representations of leadership in symbols, mythology and as transcendental and metaphysical. These conceptualisations are different from predominant Anglo-Saxon writings that frequently present leadership as linear hierarchies, dyadic (leader-follower) relationship, acts and behaviours of heroic figures and as an essentially human action. An Afro-centric indigenous concept of leadership reflecting the context is proposed which challenges heroism, linearity, individualism and objectivism
