Although corporations have been propelled to adapt eco-innovation strategies including decent work practices, responsible consumption and production, and transition from linear economy to circular economy model to integrate natural ecosystems, businesses, and waste management, inversely, the actual impact of the circular economy implementation (CEI) in Ghana is yet to be felt. This paper aims to analyse the implications of corporate green culture (CGC) on CEI behaviour, and to design a model that explains the mediating roles of environmental innovativeness (EI) and green intellectual capital (GIC) on the relation between CGC and CEI behaviour from the perspective of a lower resource economy context. Our paper is positioned on positivists' reasoning and quantitative research approach. A survey-based structured questionnaire has been used to collect data from 300 manufacturing firms in Ghana. Our hypotheses have been tested with the aid of SMART-PLS and structural equation modelling. The indicative results have shown that CGC positively affect CEI behaviour. Moreover, EI and GIC have significant and positive effects on CEI behaviour, Besides, GIC serves as a medium through which CGC indirectly impacts on CEI behaviour. The implications of the study include the emergence of baseline model to encourage CEI behaviour in Ghana and other Sub-Saharan African countries. The paper recommends that the newly developed model be used by practitioners to explain coordinated economic, ecological and social development, and restore ecological environment. Policymakers are encouraged to facilitate the reinforcement of environmental policies and subsequent realization of Sustainable Development Goals. [ABSTRACT FROM AUTHOR]

There are a number of genotypes/varieties of kenaf (Hibiscus cannabinus L) fibre in Ghana. The kenaf fibre is used in both engineering and social products and its properties improve its choice. This paper reports the tensile strength and elongation of five genotypes of the kenaf fibre in Ghana. The fibres are cultivated and harvested at maturity and prepared with water retting. A gauge length of 20 mm was used and cardboard as the initial support. The fibre diameters are found for each genotype to be 34.2 μm, 40.4 μm, 38.2 μm, 43.2 μm and 39.2 μm for EB31, TN11, EN31, PN11 and HN11 respectively. The densities are 0.53 g/cm³ for EB31; 0.60 g/cm³ for TN11; 0.63 g/cm³ for EN31; 0.94 g/cm³ for PN11 and 1.00 g/cm³ for HN11. The tensile strengths are 734.53 MPa for EB31, 1292.37 MPa for TN11, 1241.53 MPa for EN31, 979.35 MPa for PN11 and 1365.14 MPa for HN11. The corresponding percentage elongations are found to be 10.88 for EB31; 12.23 for TN11; 14.66 for EN31; 15.81 for PN11 and 13.13 for HN11. These results will make the application of fibre in various engineering applications, especially in composites, more predictive in properties and performance. [ABSTRACT FROM AUTHOR]

The objective of this research paper is to determine the critical success factors (CSFs) influencing the success of public road construction projects from the perspective of a developing nation. A self-administered questionnaire was used to gather data on the extent to which critical success factors gathered from literature impact the success of public road construction projects from sector practitioners' perspectives in Ghana. The data was then analysed using factor analysis. The study revealed that external environmental factors have the highest influence (46.23%) on public road construction project success, followed by project management factors (12.25%) while procurement-related factors have the least impact (6.97%). Public construction project management organisations and the government will now have a deeper understanding of CSFs that influence the success of public construction projects and use them as a guide to enhance the successful delivery of public road construction projects. Even though numerous studies have been undertaken to enhance the success of construction projects in Ghana, very little attention has been given to procurement-related factors. Thus, the study outcome will add value to sector practitioners and the Government of Ghana in the management of public road construction projects. [ABSTRACT FROM AUTHOR]

Primary healthcare (PHC) has become a concern in most resource constraint economies particularly in the global south where meeting this important economic need has become a burden. Given this, blockchain technology (BT), a promising transformation in contemporary service delivery, has become an alternative for service-oriented institutions to meet their desired goals. In primary healthcare, BT has been utilised to lessen the burden on medical supply chain and data management. Nonetheless, the technology seems to be a preserve of the developed economies. In the global south, not only has the complexities of the technology hindered the implementation of the technology but the understanding of its affordances has also been nascent. This study extends Task-technology fit model with the perceived e-readiness model. Drawing on the best-worst method, this paper investigates PHC managers' decision to embrace BT for PHC delivery in Ghana. The study finds that, in order of relevance, task-technology, infrastructure and individual characteristics are the main drivers of BT adoption and implementation. The study proposes the implementation of various strategies relevant to ensuring a sustainable BT for the management of PHC in resource constraint economies. [ABSTRACT FROM AUTHOR]

It depends on both the pedestrians and the building whether they can be evacuated from a building safely and quickly in any situation. Understanding pedestrian behavior is crucial when designing buildings for safe evacuation in emergencies like earthquakes and fires. Since this topic has yet to be fully explored in Ghana, we conducted experiments in a classroom to capture the characteristics of pedestrian movements during an emergency. In this experimental study, students were asked to pretend to evacuate during an emergency. The simulation and comparison of the evacuation of students from a classroom were conducted using a multi-grid model in our study. The study examines several factors that influence evacuation characteristics. These factors include pedestrian density, speed, time, door width, body mass index, and classroom capacity. The paper describes in detail all study phases, including planning, preliminary work, observational studies, empirical data collection, and statistical analysis. It thoroughly examines premovement time, group density, and velocities for groups and individuals moving through doorways, traveling distances, and walking in educational settings. A person's state of mind and psychological abilities are also taken into account, as well as their level of emotional involvement in the movement. The obtained results are also discussed for evacuation planning in educational institutions under different conditions. [ABSTRACT FROM AUTHOR]

Climatic impacts on the environment, land cover and land use change such as urbanisation and deforestation affect rainfall and change riverflow responsiveness and seasonal flows as a result of their influence on nonlinear behaviour of the catchments of rivers. Water supply is seriously affected which invariably impacts on domestic activities and agriculture. In some countries river transportation, hydropower, irrigation and fish farming are at risk due to these impacts. Within this paper, a review of existing hydrological and climatic studies in Africa and Ghana in particular is presented. The paper highlights the knowledge gaps identified in the review, such as rainfall-riverflow processes and their controls in the country, estimation of cycles in evapo-transpiration and solar radiation time series, together with the complete characterisation of the temporal and spatial fluctuations within the climate cycles. The establishment of a monograph of catchment response characteristic across the Ghanaian latitudinal gradient and if possible across the tropics is recommended. This could be used for the prediction of hydrologic response of ungauged catchments in the country. [ABSTRACT FROM AUTHOR]
