COVID-19 pandemic: ten research questions Africa must answer for itself

The COVID-19 pandemic is spreading through Africa and governments are making frantic efforts to control spread, hospitalizations and deaths. While control measures are being taken, research into the biomedical and socio-cultural aspects of the pandemic, relevant to the African population, should not be ignored. It should not be assumed that research performed in Asian, American and European populations will always be applicable to Africa. Rather, research should be done in Africa to answer questions peculiar to the epidemic on the continent and help inform international guidelines. National guidelines for treatment and prevention, patient recoveries and discharge, and public health control measures should be based on research performed in the appropriate context for them to be effective and robust. Urgent research is needed in viral immunology and shedding, treatment and prevention trials, protection of healthcare personnel, and antimicrobial use among others. In this article, we propose ten research questions that when answered in a timely manner by scientists in Africa, will enhance Africa’s response to the pandemic

Association of Researchers in Construction Management

Students studying at postgraduate level should engage in learning on higher cognitive levels such as evaluation and creation. The notion of effective learning at this level is characterised by the student's ability to use acquired knowledge and principles to solve complex problems. Learning theories advocate maximising student engagement with the learning resources in order to facilitate such effective learning. This can be achieved by addressing the following factors in curriculum design: accessibility, variety, formative assessment and the development of learning communities. This paper presents work done on a postgraduate level Project Management course to maximise the factors mentioned above, for example, with the introduction of automatically marked quizzes and the re-structuring of the course content. The content and delivery of the course was changed from weekly lectures and tutorial sessions (old system) to a web-based blended learning system (new system). Evaluation of the old and new systems was undertaken using questionnaires. The student evaluation suggests that the new system led to more effective learning. It is suggested that effective learning can be facilitated by a blended learning system

Healthcare provider perspectives on HIV cure research in Ghana

INTRODUCTION: Antiretroviral therapy (ART) has reduced mortality and improved life expectancy among HIV patients but does not provide a cure. Patients must remain on lifelong medications and deal with drug resistance and side effects. This underscores the need for HIV cure research. However, participation in HIV cure research has risks without guaranteed benefits. We determined what HIV healthcare providers know about HIV cure research trials, the risks involved, and what kind of cure interventions they are likely to recommend for their patients. METHODS: We conducted in-depth qualitative interviews with 39 HIV care providers consisting of 12 physicians, 8 counsellors, 14 nurses, 2 pharmacists, 2 laboratory scientists, and 1 community advocate from three hospitals. Interviews were transcribed verbatim and coded, and thematic analysis was performed independently by two investigators. RESULTS: Participants were happy about the success of current treatments and hopeful that an HIV cure will be found in the near future, just as ART was discovered through research. They described cure as total eradication of the virus from the body and inability to test positive for HIV or transmit the virus. In terms of risk tolerance, respondents would recommend to their patients\u27 studies with mild to moderate risks like what patients on antiretroviral therapy experience. Participants were reluctant to recommend treatment interruption to patients as part of a cure study and wished trials could be performed without stopping treatment. Healthcare providers categorically rejected death or permanent disability as an acceptable risk. The possibility of finding a cure that will benefit the individual or future generations was strong motivations for providers to recommend cure trials to their patients, as was transparency and adequate information on proposed trials. Overall, the participants were not actively seeking knowledge on cure research and lacked information on the various cure modalities under investigation. CONCLUSION: While hopeful for an HIV cure, healthcare providers in Ghana expect a cure to be definitive and pose minimal risk to their patients

The outcome of a training programme (RESPECT) on staff’s attitudes towards causes and management of aggression in a Regional Referral Hospital of Northern Uganda

Introduction Occupational violence has been demonstrated to impact negatively on the well‐being of nurses and patients. Staff attitudes towards causes and management of patients’ aggression influence their practice. Training is likely to influence attitudes towards aggression; however, Uganda's health system lacks adequate resources to provide aggression management training for staff. Aim To assess the impact of a training programme (RESPECT) on staff attitudes towards causes and management of patient's aggression in a Ugandan hospital. Methods This study used a mixed‐methods convergent design. A convenience sample of nurses and support staff employed in the psychiatric ward and other services across the hospital (N = 90) completed the Management of Aggression and Violence Attitude Scale (MAVAS) pre‐ and post‐training. The views of a smaller sample (n = 35) were captured via interviews and focus groups and analysed using thematic analysis. Results Participants reported greater agreement with patients’ physical and social environment (external and situational causative models) as factors influencing patient's aggression. Qualitative findings substantiated the results identified in the survey. Attitudes towards seclusion, restraint and medication remained unchanged. Discussion and implications for practice RESPECT has the potential to change staff attitudes towards aggression in the short term. Further research is needed to investigate long‐term effects and impact on incidents of aggression

Unwillingness of patients in Ghana to interrupt antiretroviral therapy for HIV cure research

OBJECTIVES: Though antiretroviral therapy (ART) has reduced HIV infection into a manageable chronic disease, it does not provide for a cure. HIV cure trials may carry risks for patients who are generally doing well on ART, making it imperative that their input is sought as various types of cure methods and trials are designed. Few studies have sought the views of African patients on HIV cure studies. The objective of this study was to determine the views and preferences of people living with HIV (PLWH) in Ghana on cure research. METHODS: We used a questionnaire to interview 251 PLWH in Ghana about their willingness to engage in HIV cure research. We investigated their motivations, the types of cure they would prefer and which risks were acceptable to them. RESULTS: Most participants were enthusiastic about participating in cure research and driven by both altruistic and personal motives. Patients preferred a cure where they would continue follow-up with their doctor (88%) compared to being assured that they have been completely cured and did not need further follow-up (11%). The vast majority of the respondents were risk averse. Most patients (67%) would decline to interrupt ART as part of a protocol for HIV cure research. In bivariate analysis, participants above the age of 40 years were more likely to agree to treatment interruption during cure studies (OR 2.77; 95% CI 1.21-.6.34. CONCLUSIONS: Our results show that preferred cure modalities and risk tolerance for patients in Africa may be different from those of other parts of the world. Extensive social science and behavioural studies are needed on the continent to help inform future cure trials

Employee motivation in Ghana: A factor structure and measurement tool

Purpose: This paper reports research on the factor structure of employee motivation as well as provides a tool for measuring the level of employee motivation in Ghanaian organisations. Methodology: The study was designed as exploratory, comparative and cross-sectional. 260 respondents drawn from across the gender, status and job grade hierarchy of 19 organisations participated. The organisations were matched in terms of tenure (over 5years), number of employees (50 or more) and geographic location (headquartered in Accra). A 41-item questionnaire on the Level of Motivation (LoM); Characteristics of Employee Motivation (CEM); aspects of Organisational Citizenship Behaviour (OCB); Managerial Assumptions about employee behaviour (MA); Contextual Institutional Analysis (IAN) and Organisational Leadership Issues (Le) was developed and used. The instrument combined fixed response format on a 3-point scale with open-ended responses. Findings: Exploratory Factor Analyses (Varimax Rotation, converging in 26 iterations) yielded 6 factors, which account for 60% of the variance. Thematic analyses of both interview and open-ended questionnaire data support the emergent factor structure, providing some tentative indication that employee motivation in the Ghanaian (or indeed African) context should be looked at more in an integrated manner rather than in terms of the limiting confines of any one theory of motivation. The 3 items hypothesised to constitute the measure of level of employee motivation loaded neatly onto Factor 6. One-way ANOVA demonstrated no differences in the level of motivation across the organisational samples; this was confirmed by the interview data. Implications/Originality/Value: The implications and value of this research are: that motivation research in Africa does need to focus more on developing an integrated model of employee motivation; also, a simple 3-item but novel tool for measuring the level of employee motivation as well as its underlying dynamics, is tentatively put forward. This, in the Ghanaian context, is a much needed psychometric

Cascade and Commutative Self-Assembles of Nanoscale Three-Component Systems Controlled by the Conformation of Thiacalix[4]arene

In this work, the formation of two- and three-component supramolecular systems based on cone, partial cone, 1,3-alternate stereoisomers of heteroditopic “hosts”: <i>p-tert-</i>butylthiacalix[4]arene containing 4-amidopyridine fragments with silver(I) cations and dicarboxylic acids in liquid and solid phases were studied by UV spectroscopy, dynamic light scattering, and atomic force microscopy methods. It has been shown that these macrocycles are coreceptors, capable of simultaneously binding silver(I) cations, dicarboxylic acids (oxalic, malonic, succinic, maleic, fumaric acids), and hydroxyl acids (glycol, tartaric acids). For the first time, by the dynamic light scattering method, it has been shown that the conformation of p-<i>tert</i>-butyl thiacalix[4]arenes significantly affects the type of three-component system formed: cone is characterized by the formation of cascade systems; for partial cone, intermediate systems; and for the 1,3-alternate stereoisomers, three types of three-component systems (cascade, intermediate, and commutative) were observed
