Abstract: Over the past century, the world has rapidly become urbanized, meaning more people now live in urban areas and cities than in rural areas. The mass movement of the rural poor to urban centers and cities has also changed the dynamics of poverty. Scarce employment opportunities, lack of assets, and sudden changes in economic conditions have been proposed as increasing the stress level for most urban residents, especially the poorer ones. Using a face-to-face household survey that included a six-item non-specific psychometric instrument, the data revealed how psychological distress may be patterned by socioeconomic status among urban residents in Ghana during difficult times characterized by food and fuel price hikes. The data collected in interviews of 1,158 adults (49% males and 51% females) who were 18 years and above were analyzed using multinomial logit regressions. The results confirmed previous findings and showed negative links between socioeconomic status, adverse life events, and psychological distress. Specifically, low income, low level of education, large household size, undesirable life events and being employed in agriculture was found to be associated with psychological disorders. The outcomes of this research project are consistent with previous findings-that people in lower socioeconomic strata and those who have suffered adverse events are more likely to suffer psychological distress. The implications of these results for behavioral health are discussed.

Abstract: Hearing loss affects 1 in 5 people worldwide and is estimated to affect 1 in 4 by 2050. Treatment relies on the accurate diagnosis of hearing loss however, this first step is out of reach for % of those affected. Increasingly automated approaches are being developed for self-administered digital hearing assessments without the direct involvement of professionals. This study aims to provide an overview of digital approaches in automated and machine learning assessments of hearing using pure-tone audiometry and to focus on the aspects related to accuracy, reliability, and time efficiency. This review is an extension of a 2013 systematic review. A search across the electronic databases of PubMed, IEEE, and Web of Science was conducted to identify relevant reports from the peer-reviewed literature. Key information about each report’s scope and details was collected to assess the commonalities among the approaches. A total of 56 reports from 2012 to June 2021 were included. From this selection, 27 unique automated approaches were identified. Machine learning approaches require fewer trials than conventional threshold-seeking approaches, and personal digital devices make assessments more affordable and accessible. Validity can be enhanced using digital technologies for quality surveillance, including noise monitoring and detecting inconclusive results. In the past 10 years, an increasing number of automated approaches have reported similar accuracy, reliability, and time efficiency as manual hearing assessments. New developments, including machine learning approaches, offer features, versatility, and cost-effectiveness beyond manual audiometry. Used within identified limitations, automated assessments using digital devices can support task-shifting, self-care, telehealth, and clinical care pathways.

Abstract: Although malaria or fever (as it is commonly referred to) is a major cause of morbidity and mortality in Ghana, the cost of treating the disease in the country has not been well documented. Knowledge about the cost of treating malaria can affect the health care seeking behaviour of people and justify increased expenditure for malaria control. This study used data collected from 1289 households in two districts in Ghana to estimate the direct and indirect costs of malaria treatment. Malaria was ascertained not by parasitological tests but through symptoms described by the respondents using a recall period of one month. It was found that substantial amount of time was spent in seeking malaria care and taking care of the sick, which makes the indirect cost per case of fever represent 79% of the total cost of seeking treatment in the survey area. The results provide le economic justification for malaria control. The average cost of treating an episode of the disease including direct costs and the opportunity costs of travel and waiting time amounted to $8.67 or 3.7 days of male output or 4.7 days of female output. When compared with the average five days loss of output for the patient due to malaria morbidity and caretaking, it can be concluded that the cost of controlling malaria is lower than lost earnings or the value of output.

Abstract: This study investigates the impact of exchange rate misalignment on outward capital flight in Botswana over the period 1980–2015. The study uses the autoregressive distributed lag (ARDL) approach to cointegration and the Toda and Yamamoto (1995) approach to Granger causality. Botswana’s currency misalignment was caused by current account imbalances. The most important determinant of capital flight from Botswana is trade openness, which indicates that exportable commodities are misinvoiced leading to net capital outflows. Our main findings show that in the long-run, when the currency is overvalued, the volume of capital flight through trade misinvoicing declines and increasing foreign reserves does not reduce outward capital flight. However, when the currency is undervalued, the volume of capital flight through trade misinvoicing increases and foreign reserves reduce outward capital flight. Investors respond more to prospects of devaluation than to inflation. Botswana should tolerate overvaluation of the pula of only up to 5%. When the pula is overvalued beyond 5%, capital flight increases substantially. The government has to formulate trade regulations and monitor imported and exported commodities. Botswana should also implement capital controls to limit capital smuggling and maintain monetary autonomy.

Abstract: This study utilized instrumental variable techniques and the Driscoll-Kraay estimator to examine the effect of democracy and natural resources on income inequality using a comprehensive panel dataset from 43 sub-Saharan Africa (SSA). The findings from our empirical analysis indicated that natural resources and democracy indices such as electoral, liberal, participatory, deliberative, and egalitarian drive income inequality in SSA. Regional comparative analysis also showed that the democracy indices increase income inequality in West, Central, and Southern Africa while having a neutral effect on income inequality in Eastern Africa. Natural resources were revealed to reduce income inequality in West and Southern African countries while increasing income inequality in Eastern Africa. In the case of Central Africa, natural resources play an insignificant role in income inequality. The interactive effect analysis indicates that the democracy indices interact with natural resources to increase income inequality in SSA. Finally, the democracy indices interacted with natural resources to drive income inequality in Eastern and Southern African countries while exerting an insignificant effect on income inequality in West and Central African countries. The policy implications of the findings are discussed.

Abstract: This study contributes to the literature by investigating the effect of environmental degradation on foreign direct investment (FDI) using comprehensive panel data from 103 developing countries between 1970 and 2019. In this study, nine variables, namely, CO 2 emissions, total greenhouse gas emissions, methane emissions, PM2.5, nitrous oxide emissions, ecological footprint of consumption, ecological footprint of production, total area (ecological footprint), and total biocapacity, were used to measure environmental degradation/sustainability. Using Lewbel's two‐stage least squares to control endogeneity issues, the result from the aggregated s le indicates that while CO 2 emissions significantly reduce FDI, the remaining environmental degradation variables stimulate FDI. Further analysis reveals that, generally, environmental degradation boosts FDI flows to low and lower‐middle income countries while reducing FDI flows to upper‐middle income countries. The regional analysis also shows that environmental degradation generally reduces FDI flows to Europe and Central Asia, and the Middle East and North Africa regions while stimulating FDI flows to South Asia, Sub‐Saharan Africa, Latin America, and the Caribbean. Environmental degradation was found to have a neutral effect on FDI flows to East Asia and the Pacific. These results are robust to alternative econometric techniques. The policy implications are discussed.

Abstract: Age-friendly cities are crucial to achieve the WHO goal of healthy aging. Such cities promote opportunities for health, participation, and security, thus enhancing quality of life as people age. Older people commonly experience psychosocial challenges such as anxiety, depression, substance abuse, loss of autonomy, grief, fear, and loneliness. Australian and Canadian cities continue to seek innovation to improve healthy urban aging and create more age-friendly environments for older adults. There is increasing evidence on the effectiveness and feasibility of mobile technology in health promotion and closing psychological treatment gaps. Older adults have been demonstrated to engage frequently with mobile devices, particularly text messaging. In this article, we conceptualize the Text4HealthyAging, an evidence-based text messaging innovation to support healthy urban aging in Canadian and Australian cities.

Abstract: The income inequality-economic growth linkage is a topical issue in economics and policy discussions. Both theoretical and empirical results on the impact of income inequality on economic growth have been controversial. One of the criticisms of the existing studies relates to using cross-sectional data and linear estimation techniques for empirical analysis. Capitalising on the limitations in the existing literature, this article employs the novel Quantile-on-Quantile Regression (QQR) approach to examine the relationship between income inequality and economic growth in BRICS. Applying the novel QQR technique helps to model how income inequality distributions affect the distributions of economic growth. The quantile cointegration tests reveal cointegration between income inequality and economic growth. The QQR results indicate that income inequality has a stronger negative effect on the lower and middle tails of economic growth in Brazil while having a stronger positive impact on economic growth in Russia, China and South Africa. For India, income inequality has a stronger negative effect on the lower tail of economic growth and a stronger positive impact on the middle and higher tails of economic growth. These results are consistent with quantile regression results. Further analysis from the Granger causality-in-quantiles shows that at various quantiles, a bidirectional causal relationship between income inequality and economic growth exists in China, while a unidirectional causality runs from income inequality to economic growth in Brazil and India. No causal relationship was found between income inequality and economic growth in Russia and South Africa. The policy implications are discussed.
