Research on Indigenous Knowledge and its Application: A Case of Wild Food Plants of Zimbabwe

Research on indigenous knowledge should go beyond documenting and interpreting it. Rather, it should stimulate inquiry into its application in present day community development and education settings. This study intends to steer indigenous knowledge research towards practical application initiatives. The study documents wild food plants of Zimbabwe, highlights some popular wild food plants, and cites some commercially marketed wild food plants and makes recommendations on the application of indigenous knowledge of wild food plants in community and educational settings

National environmental education policy is essential for guiding and coordinating environmental education activities within a country. The Zimbabwean Environmental Education Policy development process took place between 2000 and 2001.This paper looks at stages in the policy development process, the factors that influenced it and the lessons learnt from the process

Power/Knowledge in the Governance of Natural Resources: A Case Study of Medicinal Plant Conservation in the Eastern Cape

This article explores the power/knowledge relations at the knowledge generating interface between a modern community development organisation and a traditional health practitioner community in a town in the Eastern Cape, South Africa, through the lens of Foucaldian governmentality. This case study is part of a broader study which explores power/knowledge relationships in the representation and application of indigenous knowledges in selected environmental education and community development contexts. This study traces the various loci of power/knowledge and their implications in a project focusing on the conservation of traditional medicinal plants in which the community development organisation and traditional health practitioner community were involved as key partners. The case study provides a micro-setting to analyse natural resource governance, which reveals how power located in modern institutions is reinforced by the generation and accumulation of disciplinary (scientific) knowledge as a hegemonic regime of truth that is applied in the governance of medicinal resources. It also reveals the location of power within the traditional healer community on the other hand and how this is maintained by the resilient cultural retention of medicinal knowledge and related practices within the community against a background of dominant Western medical practice

A Curriculum Model: Engineering Design Graphics Course Updates Based on Industrial and Academic Institution Requirements

Engineering design graphics courses taught in colleges or universities should provide and equip students preparing for employment with the basic occupational graphics skill competences required by engineering and technology disciplines.  Academic institutions should introduce and include topics that cover the newer and more efficient graphics techniques and technologies developed through research by academic institutions and professional organizations as well as information obtained from experienced engineering design graphics practitioners.  This paper presents the systematic approach used at the University of Nebraska at Kearney (UNK), Department of Industrial Technology (ITEC), to update and improve its existing multidiscipline engineering design graphics course.   Twenty five engineering design graphics course syllabi, all from programs accredited by either the Association of Technology, Management, and Applied Engineering (ATMAE) or the Accreditation Board for Engineering and Technology (ABET), were reviewed in this study.  A review of the course syllabi identified 20 of the most commonly taught engineering design graphics topics.  The 20 topics were used to develop a survey instrument subsequently sent to the top 10 employers of ITEC students majoring in Construction Management, Industrial Distribution, and Telecommunications Management.  The results obtained from the employer survey were analyzed and used to update the introductory engineering design graphics course at UNK so that engineering design graphics topics taught are consistent with academia and kept current and relevant to the needs of industry

A simple mathematical model for Ebola in Africa

We deal with the following question: Can the consumption of contaminated bush meat, the funeral practices and the environmental contamination explain the recurrence and persistence of Ebola virus disease outbreaks in Africa? We develop an SIR-type model which, incorporates both the direct and indirect transmissions in such a manner that there is a provision of Ebola viruses. We prove that the full model has one (endemic) equilibrium which is locally asymptotically stable whereas, it is globally asymptotically stable in the absence of the Ebola virus shedding in the environment. For the sub-model without the provision of Ebola viruses, the disease dies out or stabilizes globally at an endemic equilibrium. At the endemic level, the number of infectious is larger for the full model than for the sub-model without provision of Ebola viruses. We design a nonstandard finite difference scheme, which preserves the dynamics of the model.

Sexually transmitted infections among HIV serodiscordant partners: A secondary analysis of HIV Prevention Trial Network 052

Sexually transmitted infections (STIs) remain a public health concern because of their interaction(s) with HIV. In the HPTN 052 study, STIs were evaluated in both HIV-positive index cases and their HIV-negative partners at enrollment and at yearly follow-up visits. Our definition for STI was based on any infection with Chlamydia trachomatis, Neisseria gonorrhoeae, syphilis, or Trichomonas vaginalis. We used log-binomial regression models to identify factors associated with prevalent STIs. Generalized estimating equation models with the Poisson distribution were used to compare STI incidence between HIV-positive index cases and HIV-negative partners. 8.1% of the participants had STIs at enrollment. The prevalence of STIs (8.9 vs. 7.2) was higher in HIV-positive index cases than HIV-negative partners. Being female (prevalence ratio (PR) = 1.61; 95% CI: 1.20–2.16) or unmarried (PR = 1.92; 95% CI: 1.17–3.14) was associated with prevalent STIs. Compared to HIV-negative male partners, HIV-positive female index cases had a higher risk of STI acquisition (incidence rate ratio (IRR) = 2.25; 95% CI: 1.70–2.97). While we are implementing HIV prevention interventions for HIV-negative people, we should also intensify targeted STI prevention interventions, especially among HIV-positive women

Problematising Local Indigenous Community Research

This book deliberates on developments related to Knowledge Pathing: Multi-, Inter- and Trans-Disciplining in Social Sciences. The book explores the value of this vexed concept in advancing the course for multi-, inter- and trans-disciplinary perspectives, methodologies, theories and epistemologies of knowledge pathing. The discourse on knowledge pathing remains critical in advancing debates and dialogues in the humanities and social sciences spaces of research and studies. This book makes a significant contribution to the scholarly understanding of indigenous knowledge research by focusing on problematising local indigenous community research from Afro-sensed perspectives. The field of indigenous knowledge research and higher education in Africa is complex. Yet, across the continent, higher education has been the sector to least embrace Indigenous Knowledge Systems (IKS) or regard indigenous science as a legitimate source of inspiration for the development of youth and local communities. Higher education institutions and local indigenous communities should thus generate knowledge and power through research. On the other hand, higher education researchers should use their research processes and skills for cross-beneficiation when engaging local indigenous communities. This book embodies the current discourse on decolonisation and the use of indigenous knowledge in research and is intended for research specialists in the field of indigenous knowledge systems

A Phase 2b Study to Evaluate the Safety and Efficacy of VRC01 Broadly Neutralizing Monoclonal Antibody in Reducing Acquisition of HIV-1 Infection in Women in Sub-Saharan Africa: Baseline Findings

Background: HIV Vaccine Trials Network 703/HIV Prevention Trials Network 081 is a phase 2b randomized, double-blind, placebo-controlled trial to assess the safety and efficacy of passively infused monoclonal antibody VRC01 in preventing HIV acquisition in heterosexual women between the ages of 18 and 50 years at risk of HIV. Participants were enrolled at 20 sites in Botswana, Kenya, Malawi, Mozambique, South Africa, Tanzania, and Zimbabwe. It is one of the 2 Antibody Mediated Prevention efficacy trials, with HIV Vaccine Trials Network 704/HIV Prevention Trials Network 085, evaluating VRC01 for HIV prevention. Methods: Intense community engagement was used to optimize participant recruitment and retention. Participants were randomly assigned to receive intravenous VRC01 10 mg/kg, VRC01 30 mg/kg, or placebo in a 1:1:1 ratio. Infusions were given every 8 weeks with a total of 10 infusions and 104 weeks of follow-up after the first infusion. Results: Between May 2016 and September 2018, 1924 women from sub-Saharan Africa were enrolled. The median age was 26 years (interquartile range: 22-30), and 98.9% were Black. Sexually transmitted infection prevalence at enrollment included chlamydia (16.9%), trichomonas (7.2%), gonorrhea (5.7%), and syphilis (2.2%). External condoms (83.2%) and injectable contraceptives (61.1%) were the methods of contraception most frequently used by participants. In total, through April 3, 2020, 38,490 clinic visits were completed with a retention rate of 96% and 16,807 infusions administered with an adherence rate of 98%. Conclusions: This proof-of-concept, large-scale monoclonal antibody study demonstrates the feasibility of conducting complex trials involving intravenous infusions in high incidence populations in sub-Saharan Africa
