'Colonial virus'? Creative arts and public understanding of COVID-19 in Ghana

In this paper I examine how responses to COVID-19 by Ghana’s creative arts communities shape public understanding of the pandemic. I focus on comedy, music, textile designs, and murals created between March and August 2020, through frameworks of the social psychology of everyday knowledge and arts and health. The art forms perform three functions: health promotion (songs), improving environmental aesthetics (murals), and memorialising (textile designs). Similar to arts-based interventions for HIV and Ebola, Ghanaian artists translate COVID-19 information in ways that connect emotionally, create social awareness, and lay the foundation for public understanding. Artists translate COVID-19 information in ways that connect emotionally, create social awareness, and lay the foundation for public understanding. Some offer socio-political critique, advocating social protection for poor communities, re-presenting collective memories of past health crises and inequitable policy responses, and theorising about the Western origins of COVID and coloniality of anti-African vaccination programmes. I consider the implications for COVID public health communication and interventions

“Colonial virus”: COVID-19, creative arts and public health communication in Ghana

Since March 2020, Ghana's creative arts communities have tracked the complex facets of the COVID-19 pandemic through various art forms. This paper reports a study that analysed selected 'COVID art forms' through arts and health and critical health psychology frameworks. Art forms produced between March and July 2020, and available in the public sphere - traditional media, social media and public spaces - were collated. The data consisted of comedy, cartoons, songs, murals and textile designs. Three key functions emerged from analysis: health promotion (comedy, cartoons, songs); disease prevention (masks); and improving the aesthetics of the healthcare environment (murals). Textile designs performed broader socio-cultural functions of memorialising and political advocacy. Similar to earlier HIV/AIDS and Ebola arts interventions in other African countries, these Ghanaian COVID art forms translated public health information on COVID-19 in ways that connected emotionally, created social awareness and improved public understanding. However, some art forms had limitations: for example, songs that edutained using fear-based strategies or promoting conspiracy theories on the origins and treatment of COVID-19, and state-sponsored visual art that represented public health messaging decoupled from socio-economic barriers to health protection. These were likely to undermine the public health communication goals of behaviour modification. We outline concrete approaches to incorporate creative arts into COVID-19 public health interventions and post-pandemic health systems strengthening in Ghana

Validation of the multidimensional WHOQOL-OLD in Ghana: A study among population-based healthy adults in three ethnically different districts

Objectives: Study of well-being of older adults, a rapidly growing demographic group in sub-Saharan Africa, depends on well-validated tools like the WHOQOL-OLD. This scale has been tested on different populations with reasonable validity results but has limited application in Africa. The specific goal of this paper was to examine the factor structure of the WHOQOL-OLD translated into three Ghanaian languages: Ga, Akan, and Kasem. We also tested group invariance for sex and for type of community (distinguished by ethnicity/language). Methods: We interviewed 353 older adults aged 60 years and above, selected from three ethnically and linguistically different communities. Using a cross-sectional design, we used purpose and convenience methods to select participants in three geographically and ethnically distinct communities. Each community was made up of selected rural, peri-urban, and urban communities in Ghana. The questionnaire was translated into three languages and administered to each respondent. Results: The results showed moderate to high internal consistency coefficient and factorial validity for the scale. Using confirmatory factor analysis, we found that the results supported a multidimensional structure of the WHOQOL-OLD and that it did not differ for males and females, neither did it differ for different ethnic/linguistic groups. Conclusions: We conclude that the translated versions of the measure are adequate tools for evaluation of quality of life of older adults among the respective ethnic groups studied in Ghana. These results will also enable comparison of quality of life between older adults in Ghana and in other cultures

Ownership Rights and Investment in Agricultural Land in Ghana: A Gender Analysis

This paper examines the relationship between ownership rights and investment in agricultural land from a gender perspective in Ghana, using the Two-Stage Conditional Maximum Likelihood estimation technique and data from the Ghana Household Asset Survey. The results indicate that investment in agricultural lands is generally low in Ghana and tends to occur mostly in agricultural lands owned by men suggesting its inability to enhance tenure security. Furthermore, investment in agricultural lands owned by men is associated with a wider range of ownership rights. However, the same cannot be said about agricultural land owned by women as investments in their land do not significantly improve their rights to the land. Except for economic rights that appear to have a significant negative association with investments in agricultural lands owned by women, all other rights have no significant relationship with investments in agricultural lands owned by both men and women. There is a positive relationship between age and ownership rights for men suggesting that the youth may have challenges securing their tenure. We recommend the strengthening of the current land administration projects to enhance tenure security. Policies that will support the growing of perennial trees, construction of farmhouses and irrigation should be put in place by the government to encourage men to undertake such investments as they tend to improve ownership rights of agricultural lands. More should also be done to secure the ownership rights of the youth if the government wants them to engage in agriculture

Volatility persistence in cryptocurrency markets under structural breaks.

This paper deals with the analysis of volatility persistence in 12 main cryptocurrencies (Bitcoin, Bitshare, Bytecoin, Dash, Ether, Litecoin, Monero, Nem, Ripple, Siacoin, Stellar and Tether) taking into account the possibility of structural breaks. Using fractional integration methods, the results indicate that both absolute and squared returns display long memory features, with orders of integration confirming the long memory hypothesis. However, after accounting for structural breaks, we find a reduction in the degree of persistence in the cryptocurrency market. The evidence of persistence in volatility imply that market participants who want to make gains across trading scales need to factor the persistence properties of cryptocurrencies in their valuation and forecasting models since that will help improve long-term volatility market forecasts and optimal hedging decisions.pre-print532 K

Effects of Fish Cage Culture on Water and Sediment Quality in the Gorge Area of Lake Volta in Ghana: A Case Study of Lee Fish Cage Farm

The study determined the impacts of fish cage farming on the gorge area of Lake Volta. Water and sediment samples were collected from six sites in the Lee Cage Farm; four from sections with cages and two from about 1300 m upstream of the farm which served as the control. Water quality variables monitored were pH, temperature, dissolved oxygen, nitrate-nitrogen, ammonia-nitrogen, orthophosphate, faecal coliforms and total coliforms. Variables monitored in the sediment were organic matter, total carbon, total nitrogen and total phosphorus. There were variations in water quality between the farmed and control sites but the differences were not significant (p > 0.05). The mean counts of total coliform in the water ranged from 940 - 3318 cfu/100 ml while faecal coliforms ranged from 113 - 552 cfu/100 ml at the farmed site. The mean total coliform count at the control site ranged from 837 - 6960 cfu/100 ml while the faecal coliforms ranged from 48 - 120 cfu/100 ml. Therefore, there was significant variation between the faecal coliforms count at the two sites (p = 0.046). The results suggest that the general microbiological quality of the water at the study area was unacceptable

Financial stress spillover across Asian Countries.

This paper uses fractional integration techniques to explore the stochastic properties of the Financial Stress Indices (FSIs) of 10 Asian countries, further investigating the bilateral linkages between them to ascertain how financial stress spreads among countries in the region. For the FSIs of each country, the results show that all the estimated orders of integration are in the interval (0, 1) implying fractional integration and a long memory pattern. Thus, shocks will have transitory though long‐lasting effects. For the cross‐country spillovers of the FSIs, we find that convergence is satisfied in all cases with values of the differencing parameter around 0 and thus showing short memory behavior. It is worth noting that for the larger economies in the region, Japan and China, financial stress transmission between Japan and the smaller economies was faster than with respect to China. Overall, the results provide valuable information on the financial market activity of the countries in the region. To check for the robustness of the baseline results we also use systemic risk measures for these countries, CoVaR with the results showing evidence of fractional integration for the individual series, with all values of the differencing parameter in the range (0, 1). For convergence, there is a substantial reduction in the degree of integration, though the results are not as clear as with the FSIs.pre-print412 K

Cryptocurrencies and stock market indices. Are they related?

In this paper, we investigate the stochastic properties of six major cryptocurrencies and their bilateral linkages with six stock market indices using fractional integration techniques. From the univariate analysis, we observe that for Bitcoin and Ethereum, the unit root null hypothesis cannot be rejected; for Litecoin, Ripple and Stellar, the order of integration is found to be significantly higher than 1; for Tether, however, we find evidence in favour of mean reversion. For the stock market indices, the results are more homogeneous and the unit root cannot be rejected in any of the series, with the exception of VIX where mean reversion is obtained. Concerning bivariate results within the cryptocurrencies and testing for cointegration, we provide evidence of no cointegration between the six cryptocurrencies. Along the same lines, testing for cointegration between the cryptocurrencies and the stock market indices, we find evidence of no cointegration, which implies that the cryptocurrencies are decoupled from the mainstream financial and economic assets. The findings in this paper indicate the significant role of cryptocurrencies in investor portfolios since they serve as a diversification option for investors, confirming that cryptocurrency is a new investment asset class.pre-print394 K

Can Action Research Strengthen District Health Management and Improve Health Workforce Performance? A Research Protocol.

The single biggest barrier for countries in sub-Saharan Africa (SSA) to scale up the necessary health services for addressing the three health-related Millennium Development Goals and achieving Universal Health Coverage is the lack of an adequate and well-performing health workforce. This deficit needs to be addressed both by training more new health personnel and by improving the performance of the existing and future health workforce. However, efforts have mostly been focused on training new staff and less on improving the performance of the existing health workforce. The purpose of this paper is to disseminate the protocol for the PERFORM project and reflect on the key challenges encountered during the development of this methodology and how they are being overcome. The overall aim of the PERFORM project is to identify ways of strengthening district management in order to address health workforce inadequacies by improving health workforce performance in SSA. The study will take place in three districts each in Ghana, Tanzania and Uganda using an action research approach. With the support of the country research teams, the district health management teams (DHMTs) will lead on planning, implementation, observation, reflection and redefinition of the activities in the study. Taking into account the national and local human resource (HR) and health systems (HS) policies and practices already in place, 'bundles' of HR/HS strategies that are feasible within the context and affordable within the districts' budget will be developed by the DHMTs to strengthen priority areas of health workforce performance. A comparative analysis of the findings from the three districts in each country will add new knowledge on the effects of these HR/HS bundles on DHMT management and workforce performance and the impact of an action research approach on improving the effectiveness of the DHMTs in implementing these interventions. Different challenges were faced during the development of the methodology. These include the changing context in the study districts, competing with other projects and duties for the time of district managers, complexity of the study design, maintaining the anonymity and confidentiality of study participants as well as how to record the processes during the study. We also discuss how these challenges are being addressed. The dissemination of this research protocol is intended to generate interest in the PERFORM project and also stimulate discussion on the use of action research in complex studies such as this on strengthening district health management to improve health workforce performance

Re-examination of risk-return dynamics in international equity markets and the role of policy uncertainty, geopolitical risk and VIX: Evidence using Markov-switching copulas.

This study re-examines the empirical relationship between risk and return from 1994m12 to 2020m08 in fifteen international equity markets employing the novel time-varying Markov switching copula models. We provide first-time insightful evidence of time-varying Markov tail dependence structure and dynamics between risk and return in international equity markets. Results show that the dependence structure is positive for USA, UK, Germany, Italy, Brazil, Australia, Taiwan, Canada, Mexico, Japan, France and South Africa and negative for Singapore, India, Japan and China. Finally, we document the effects of policy uncertainty, geopolitical risk and VIX conditional on different markets states.post-print433 K
