Abstract:
The study seeks to assess the structure of the economy of Ghana in terms of changes in the economic structure before and after the production of oil in commercial quantities. This is viewed with regards to economic multipliers, sectoral interdependence and trade concentration. The results show that changes occurred with regards to multipliers and sectoral interdependence. The output multipliers of most sectors have declined. The results also show that the agricultural sector experienced an initial decline in its growth while industry experienced an increase.

Abstract:
Abstract The degree of the banking sector concentration is a structural variable and refers to the number of banks in the system and the degree of their market power. The importance of measuring concentration in the banking sector stems from the causal relationship between the market structure and the competitive behaviour of market participants. Traditional models measuring the banking sector competition proceed from the market structure and concentration measures. In contrast, modern approaches to measuring competition rely on non-structural models and analysis of the behaviour of market par

Abstract:
In this paper, the detection for two kinds of cracks is studied: (1) linear notch crack; (2) nonlinear breathing crack. A pitch-catch method with piezoelectric wafer actives sensors (PWAS) is used to interrogate an aluminum plate with a linear notch crack and a nonlinear breathing crack respectively as two cases. The inspection Lamb waves generated by the transmitter PWAS, propagate into the structure, interact with the crack, acquire crack information and are picked up by the receiver PWAS. The linear notch crack case is investigated through: (1) analytical model developed for Lamb waves inte

Abstract:
The commercial space transportation industry is rapidly growing with increasing numbers of spaceflight participants (SFPs). These private individuals receive considerably less training than astronauts before embarking on space missions, which presents an urgent need to develop the cognitive ergonomics that simplify spacecraft cockpit design. Neuroergonomics is an emerging area within cognitive ergonomics, which Parasuraman described as “the study of brain and behavior at work”. This experimental study investigated the neuroergonomics of cursor control devices (CCDs) for spacecraft cockpits by

Abstract:
This paper aims to evaluate a number of spatial aspects of Brazils current trade policy, emphasizing those relating to economic integration in general, and bilateral trade with Argentina in particular. A national computable general equilibrium model was developed and implemented (EFES-ARG), in order to evaluate the sectoral impact of different trade integration strategies with specific economic countries/blocs. Moreover, EFES-ARG was integrated with an interstate trade model such that the national results obtained were regionalized. The analysis of the short-run regional aspects of Brazilian t

Abstract:
The last decade has brought a row of substantial changes that have profound implications for the traditional hydrocarbon resource-rich economies. Economic conditions may change radically either throughout a decade or within months. The question is whether there is no other option for a hydrocarbon resource-rich economy than to be held hostage to the fluctuations in global oil prices. The general answer to a changing environment is: Adapt! From the macroeconomic perspective, this means diversifying the economy to broaden the income base and significantly reduce the dependence on oil revenues. T

Abstract:
The report provides a review of how risk is conceived of, modelled, and mapped in studies of infectious water, sanitation, and hygiene (WASH) related diseases. It focuses on spatial epidemiology of cholera, malaria and dengue to offer recommendations for the field of WASH-related disease risk mapping. The report notes a lack of consensus on the definition of disease risk in the literature, which limits the interpretability of the resulting analyses and could affect the quality of the design and direction of public health interventions. In addition, existing risk frameworks that consider diseas

Full text
Abstract:
Digital Public Infrastructure (DPI) is the foundation for digital transformation of economies. The goal of digital transformation in government is to create a more transparent, efficient, and responsive public sector that meets the evolving needs of citizens. Ethiopian government has developed legal and regulatory frameworks and launched several initiatives over the last decade to enhance DPI and digitalization. Accordingly, the strategy for digitalization was launched in July 2020 with four cross-sectoral areas: infrastructure, supporting systems, digital interaction, and digital ecosystem. T
