    Effectiveness of peer to peer strategy in reducing accidents and injuries at a selected platinum mine in Zimbabwe
    (Springer, 2021) Ndlovu, B.; Nunu, W.N.; Mudonhi, N.; Moyo, N.; Murwira, T.S.
    The selected mining company implemented the "Peer to Peer" strategy in 2008 to fast track achievement of zero tolerance to injuries and fatalities incidents at its workplace. Our study, therefore, sought to assess the effectiveness of this strategy in reducing accidents and injuries at this selected platinum mine in Zimbabwe. A mixed-method cross-sectional survey was conducted on 32-day shift employees using a semi-structured questionnaire with closed and open-ended questions. Furthermore, incident trend analysis was done on data obtained from the records from 2004 to 2017. Covert observations were then employed to triangulate findings from data collected using the questionnaire on practices. The tests Hotelling, Chi-square, time series plots, and Multiple Logistic Regressions were employed to compare the variables of interest before and after implementing the peer to peer strategy. There was a significant drop in the number of incidents after implementing the peer to peer strategy. There was no association between tested demographic characteristics and the level of employees’ knowledge of the strategy. Employees were afraid to implement the strategy to their superiors fully. Findings pointed out that this strategy was effective despite being part of a cocktail of strategies. There was a vast decrease in the rate of occurrence of incidents after the implementation of this strategy. However, there is a need for engagement to address the subordinate management dynamics that was observed to be a threat in the comprehensive implementation of this strategy.

    Survey on prevalence of cataract in selected communities in Limpopo Province of South Africa
    (Elsevier, 2020) Nunu, W.N.,; Ndou, N.D.; Manyange, B.S.; Ramakuela, N.J.; Manganye, B.S.; Tshivhase, S.E.; Mambanga, P.; Murwira, T.S.
    Background: Over three-quarters of all blindness worldwide are preventable and usually caused by cataract. However data on the prevalence and risk factors about cataract are not always available in South Africa. This study sought to determine prevalence and factors associated with cataracts in selected communities in Limpopo Province of South Africa. Methods: A population-based cross-sectional survey was conducted on respondents aged 18 years and above in selected villages of Vhembe District. Visual Acuity (VA) was evaluated at 6 m using Snellen’s E chart whilst eye examinations were conducted using torch light, 2.5 X magnifying lenses and an ophthalmoscope. Chi Squared tests ( χ2 ) and Multiple Logistic Regressions (MLRs) were conducted to determine associations of different variables using STATA V 13 SE. Results: About 387 out 467 targeted respondents participated in the study. Household heads were the majority of the respondents (246; 63.6%). Cataract prevalence amongst r5espondents was estimated at 44% of which 261 (67.4%) were females with 3.1% of the respondents having permanent blindness. Cataract knowledge still remains low as 228 (58.9%) and Age of respondent, gender specific, marital status, occupation, and primary care giver were significantly associated with prevalence of cataracts. Conclusions: There is an urgent need to improve eye care services so as to improve access to cataract surgery as soon as one is diagnosed. There is also need to conduct community awareness campaigns that are gender specific so as to improve community members’ knowledge on cataracts and ensure they develop proactive eye services seeking behavior. This would minimize chances of the community members suffering permanent blindness due to cataracts.
