Kursah, M. B. (2023). Satellite image analysis of thermal comfort for a sustainable urban ecology of Winneba, Ghana. Urban Climate, 52,
Abstract
To mitigate thermal heat effects for a sustainable urban living environment through planning and interventions, studies on land surface temperature (LST) in urban settings are crucial. Thus, the relationship between LST and surface landscape must be established to accurately assess the impacts of surface temperature changes for planning purposes. This will help gain knowledge about the spatial concentration of the heat effects and to design practical needs of urban planning. The study aimed to analyse and reveal the spatial dynamics of LST and its statistical relationship with two normalised satellite indices using Landsat satellite data. The Landsat-derived LST is validated using the MODIS surface temperature data. It also mapped the heat spots (HS) and evaluated the ecological evaluation index and thermal comfort using the thermal field variance index (TFVI). The results showed spatial variation in LST even within the built-up areas due to heterogeneity in the surface characteristics. Thus, localised heat islands (HIs) exist within short distances. The analysis established an inverse correlation for LST-NDVI and a direct correlation for LST-NDBI. The vegetation and water surfaces served as important heat reduction sinks while heavily built-up areas and the hardened-clayey bare surfaces served as heat-enhancing sources. More than half (52.80%) of the study area enjoys an excellent (48.57%) and good (4.23%) ecological evaluation index, indicating excellent to good thermal comfort. Much of these areas are in the urban periphery. Also, more than one-third (38.96%) enjoy the worst (34.85%) and worse (4.11%) ecological evaluation index and thus high thermal discomfort. Identifying these HS areas and evaluating the thermal comfort will help the planners and decision-makers to fully evaluate the thermal consequences of different landuse or land development scenarios and therefore improve the scientific basis of future planning and regulations.

Sam, E. F., Odame, P. K., & Amoah-Nuamah, J. (2023). Predictors of distractive activities to walking in Accra, Ghana. Urban, Plannng and Transport Research, 11,
Abstract
Walking is a fundamental mode of transport for many people globally, with immense health and environmental benefits. However, increased walking is associated with an increased risk of road traffic crashes and injuries, especially where traffic enforcement is poor, and pedestrians could easily be distracted. Despite this, a plethora of evidence exists on driver distraction; however, there is a dread of evidence of pedestrian distraction (i.e. distracted walking), particularly in Africa. This paper uses a quantitative methodology to examine the predictors of distractive activities to walking in Accra, Ghana. The study surveyed 400 pedestrians within Accra’s Central Business District (CBD). A questionnaire was deployed via Kobo Toolkit and Jamovi was used in analysing the data. The study observed that three of the top four distractive activities to walking were digital devices-related (e.g. the use of mobile phones). We found that listening to music, making, receiving phone calls, and conversing with other people while walking are the main distractive activities. The binary logistic regression model found sex, age, level of education, occupation, reasons for walking, weekly time for walking and time for common trips as significant predictors of distractive activities to walking.

Abstract
Access to public transport services is crucial to the enjoyment of various life-enhancing opportunities by persons with disabilities (PWDs). However, the attainment of such services is confronted with varying levels of difficulties due to the non-conformity between transport service delivery and PWDs’ needs. While many players like transport operators and vehicle manufacturers contribute to the delivery of transport services, this study examines the responsiveness of public transport operators to the travel needs of commuters with disabilities in Accra. Using a qualitative research approach, 24 public transport operators were conveniently sampled from 3 popular and busy transport terminals in Accra, the capital city of Ghana. Thematic content analysis was employed using key constructs that emanated from the transcripts. The findings reveal that none of the public transport providers/operators had any knowledge of Ghana’s Disability Act of 2006 and its transport provision. By this, all activities tailored to the disability population were generally informed by common sense despite refuting calls to acquire disability-friendly vehicles or support systems. It is recommended that sensitization on the transport provision of Ghana’s Disability Act should be heightened by the Ministry of Transport given its ability to improve transport services to the disability population.

Ofosu Ankrah, J. & Amoako-Gyampah, A. K. (2021). Prophetism in the wake of a pandemic: charismatic Christianity, conspiracy theories, and the Coronavirus outbreak in Africa.. Research in Globalization, 3,
Abstract
The outbreak of COVID-19 subjected prophets and the prophetic ministry to ridicule and taunts by both disenchanted Christians and non-believers alike. This study examines responses to these challenges posed by COVID-19 to prophets and the prophetic movement in Africa. The study shows that Charismatic Christianity on the continent may serve as useful resource for public education amidst the COVID-19 pandemic, but also, a source of public health misinformation and thus, create doubts, uncertainties and fear. The paper argues that, the Covid-19 pandemic has both prospects and challenges for prophecies, as well as greater implications for Char- ismatic Christianity in Africa

Amoako-Gyampah, A. K. (2022). Sanitary Inspection, Mosquito Control and Domestic Hygiene in the Gold Coast [Ghana] from the late nineteenth to the mid-twentieth century.. Social History of Medicine, 35,
Abstract
Mosquito control was the focus of many public health interventions in the Gold Coast because, during the colonial period, malaria and other mosquito-borne diseases remained a leading cause of European and African morbidity and mortality. Tagging along with theories of racial ecology that portrayed Africans and their surroundings as the nidus of infection, and therefore, perceiving African homes as a source of danger, colonial officials targeted the fight against mosquito at African households and surroundings. Sanitary inspectors were deployed to African households to search, prosecute and fine householders whose environment harboured larvae. By examining the connection between household sanitary inspection, mosquito control and domestic hygiene, this article demonstrates how sanitary inspection was not limited to finding larvae. Instead, it became a tool for checking general cleanliness in African households, and therefore, provided the colonial administration, the means to regulate, and manipulate African habits and practices in the domestic sphere.

Amoako-Gyampah, A. K. (2022). The Public Health Question and Mortuary Politics in Colonial Ghana.. Social History, 47,
Abstract
British colonial rule in Ghana profoundly affected the interment of corpses. The practice of home burials was widespread in nineteenth-century Ghana. Guided by prevailing Euro-Western discourses on sanitation and public health, colonial officials banned home interment and introduced cemeteries. This article examines the imposition of cemetery burials in colonial Ghana, the responses of the local population, its impact on indigenous burial practices, and its ramifications beyond the public health imperative. I argue that, despite initial opposition, the colonial administration succeeded in imposing cemeteries and this reoriented the people’s beliefs and practices regarding burial rituals, with spiritual and pragmatic implications for health, identity and the use of space; it also reoriented the people’s perceptions of the relationship between the living and the dead. The widespread acceptance of cemeteries was accompanied by a penchant by chiefs and other notables to create private cemeteries exclusively for their families. This threatened the spatial planning policies of the colonial administration, especially in urban areas, forcing them to strictly regulate the creation of cemeteries, limiting burials to public cemeteries, and closing already demarcated ones. Chiefs exploited cemeteries to flex power by imposing customary fees and sanctions, and by forcing their opponents to exhume their buried relatives.

Abstract
In late December 2019, strange pneumonia was detected in a seafood market in Wuhan, China which was later termed COVID-19 by the World Health Organization. At present, the virus has spread across 232 countries worldwide killing 2,409,011 as of 17 February 2021 (9:37 CET). Motivated by a recent dataset, knowledge gaps, surge in global cases, and the need to combat the virus spread, this study examined the relationship between COVID-19 confirmed cases and attributable deaths at the global and regional levels. We used a panel of 232 countries (further disaggregated into Africa-49, Americas-54, Eastern Mediterranean-23, Europe-61, Southeast Asia-10, and Western Pacific-35) from 03 January 2020 to 28 November 2020, and the instrumental variable generalized method of moment’s model (IV-GMM) for analysing the datasets. The results showed that COVID-19 confirmed cases at both the global and regional levels have a strong positive effect on deaths. Thus, the confirmed cases significantly increase attributable deaths at the global and regional levels. At the global level, a 1% increase in confirmed cases increases attributable deaths by 0.78%. Regionally, a 1% increase in confirmed cases increases attributable deaths by 0.65% in Africa, 0.90% in the Americas, 0.67% in the Eastern Mediterranean, 0.72% in Europe, 0.88% in Southeast Asia, and 0.52% in the Western Pacific. This study expands the understanding of the relationship between COVID-19 cases and deaths by using a global dataset and the instrumental variable generalized method of moment’s model (IV-GMM) for the analysis that addresses endogeneity and omitted variable issues.

Tamakloe, R., Sam, E. F., Bencekri, M., Das, S., & Park, D. (2022). Mining groups of factors influencing bus/minibus crash severities on poor pavement condition roads considering different lighting status. Traffic Injury Prevention, ,
Abstract
Objective: This study employs a data mining approach to discover hidden groups of crash-risk factors leading to each bus/minibus crash severity level on pothole-ridden/poor roads categorized under different lighting conditions namely daylight, night with streetlights turned on, and night with streetlights turned off/no streetlights. Methods: The bus/minibus data employed contained 2,832 crashes observed on poor roads between 2011 and 2015, with variables such as the weather, driver, vehicle, roadway, and temporal characteristics. The data was grouped into three based on lighting condition, and the association rule data mining approach was applied. Results: Overall, most rules pointing to fatal crashes included the hit-pedestrian variable, and these crashes were more frequent on straight/flat roads at night. While median presence was highly associated with severe bus/minibus crashes on dark-and-unlighted roads, median absence was correlated with severe crashes on dark-but-lighted roads. On-street parking was identified as a leading contributor to property-damage-only crashes in daylight conditions. Conclusions: The study proposed relevant countermeasures to provide practical guidance to safety engineers regarding the mitigation of bus/minibus crashes in Ghana.
