New International Airport, Accra

An airport as the name implies is an interface between different modes of transportation between either aerial and land or water transportation. It is a place where planes land and take-off. The enplaning and deplaning of passengers and for goads to be loaded and of f loaded, and also for planes to be serviced. At the beginning of aviation history, when it was known as an aerodrome the only function it performed was the provision of landing strips and storage space for aircrafts. With the growing importance of air-transportation, the airport has grown to become a complexity of elements which together act as an infrastructure for air-transportation. It also provides certain business and social services such as banking, shopping; postal facilities, in very modern facilities, swimming pools discotheques and playing grounds (mosques etc.) can be found. They also serve as a place of interest for site seeing. The airport has grown to a point where it is now a micro settlements which has to be considered in relation to its total environment.

New Iterative Methods With Errors Of Common Fixed Points For Multivalued Φ-Strongly Pseudo-Contractive Mappings In Banach Space

This thesis is an introduction and study of ”New iterative methods with errors of common fixed points for multivalued φ-strongly pseudocontractive mappings in Banach space” in which iteration processes used by Mann and Ishikawa with errors. The chief results that are obtained in this research is the convergence theorem of Ishikawa iteration processes for approximation of common fixed points for multivalued φ-strongly pseudocontractive mappings with errors. The focus of this thesis is in twofold: first we introduce and study a new class of Ishikawa iteration processes with errors for multivalued mappings in real Banach space; secondly,some convergence theorems of Ishikawa iteration sequences with errors for approximation of the fixed points of multivalued φ-strongly pseudocontractive mappings. The research begins with a general introduction of fixed point theory. In particular, a detailed description of existence, uniqueness and approximation of fixed points of a given Lipschitz continuous mapping in general complete metric space is provided. Especially, the exciting case of multivalued pseudocontractive and multivalued accretive mappings in Banach space together with the duality mappings are highlighted. We finally conclude the introduction with a vivid description of Mann and Ishikawa iteration schemes employed in the approximation of fixed points of multivalued mappings; notably the implicit iterative schemes and explicit iterative schemes;. The last part, and indeed the larger part, of the research is directed to the multivalued φ-strongly pseudocontractive mappings and the analyses involved. In this research, detailed proofs of subsidiary results leading up to the main theorem of multivalued φ-strongly pseudocontractive mappings are offered. The main theorem is then demonstrated in a series of lemmas and some convergence theorems of the underlying iteration procedures are also proved.

A New Paradigm Design of Commercial Centre in Tema, Ghana.

The aim of the thesis is to develop an ever vibrant commercial centre by introducing recreational facilities surveyed from a suburban community in Tema. It evaluates the key attributes of major commercial centres in Accra and Tema that may be adopted for the development of a new design model of commercial centres. It also outlines the general concepts and trends of commerce, and operative methods of the major types worldwide to develop a general guideline to realise the new model. Hopefully, the new way of designing the centres would make them friendlier, less stressful and more fun to shop in thereby developing an ever vibrant centre of commerce. The methods used are, literature review on existing concepts and trends of commerce and current types of commercial centres in the above cities. Questionnaires were distributed to shoppers, sellers and residents of community 22 in Tema on their preferred commercial centres and pull factors. Interviews were conducted at Tema Development Corporation and Accra Municipal Assembly on types of commercial centres existing in the study areas. Studies were also conducted on major design approaches locally and internationally for an understanding of their functioning. The results outline two major types of commercial designs; the traditional market style (60%) and the modern mall style (40%). Most of the residents in the study areas require entertainment facilities such as a golf course and a table tennis court which are the major pull factors aside the normal restaurant and sale points. The results obtained helped to design a new prototype commercial centre by merging the two major types of designs on an actual site in Tema and adding the community based pull factors mentioned above. Two sets of conclusions and recommendations were made: theoretical, based on literature review and case studies and practical; based on findings on community 22 (resident community for the model).

The New Kaleo-Naa's Palace at Kaleo, Upper West Region, Ghana; an Emblem of Dagaaba Traditional Architecture

A palace is the official residence of a chief, the traditional administrative head of a village. The palace primarily provides accommodation for the chief as well as space for activities related to the traditions and culture of the people. In many villages in Northern Ghana, the disposition of the palace reflects the eminence, power and respect the chief commands. It also is a mark of how much significance the people attach to the traditions. The Kaleo Naa's Palace as the largest building in the area shall be a masterpiece of Dagaaba heritage revival architecture, ranking among the best examples in the Sub-Saharan Africa. The Palace shall illustrate regionalism in totality: use of on-site or locally available materials; harmony with the surrounding landscape; strong ties to local architectural traditions; and the appearance of having been constructed by native craftsmen using primitive tools This thesis therefore describes in detail the creation processes of this Dagaaba heritage resource and dwelling place of the Paramount Chief of the Kaleo Traditional Area, Naa Bananwini Sandu II and which is opened to people of all traditions and cultures; indigenes, tourists and the public in general.

New Supreme Court Building, Accra

The purpose of this design thesis is to provide an appropriate solution to the problems faced by the Supreme Court of Judicature, Ghana related to accommodation, circulation systems and other ancillaries Objective : The objective is to conduct a thorough study into the function of the judiciary, vis-a-vis the level of facilities at its disposal. This study is expected to find a basis for the proposal of a new court house for the nation’s three superior courts which collectively constitute the Supreme Court of Judicature. SCOPE: Under article 126 (1) of the Fourth Republican Constitution of 1992, the Judiciary shall consist of a. the Supreme (Superior) Court of Judicature comprising i. The Supreme Court ii. The Court of Appeal iii. The High Court and Regional Tribunals b. Such lower courts and tribunals as Parliament may by Law establish. Basically the scope of this study shall be restricted to research work leading to design proposals for the Supreme Court of Judicature being the three Courts: The Supreme Court: The Court of Appeal and The High Court of Justice- This thesis project shall not make any proposals for the Regional tribunal because its mode or exercise of power differs from those of the three main Superior Courts listed above. It shall be assumed that the Greater Accra Regional tribunal shall occupy the present premises of the Supreme Court of Ghana whilst the proposals for the new Court house are implemented. Thus basically the scope would entail the General space and service needs of the Supreme Court, the Court of Appeal and High Court of Justice. Those include: 1. Court rooms and their appendages. 2. Justices? Chambers and suites. 3. Offices for Registries 4. Offices for administration 5. Parking facilities for all court room participants and administrative staff 6. Storage facilities 7. Landscaping 8. Other ancilliaries Mode of Presentation This report is presented in parts in order of execution of study. The First stage inception and feasibility deals with the problem identification and objectives. The feasibility study is composed of documentation and analysis of the situation at the Supreme Court of Judicatures present premises. This is to investigate the authenticity of the problem defined and to serve as an exhibit for justification and basis for formulation of a statement of intent. The Second stage is the brief elaboration stage which deals with the outline of proposals emanating from the statement of intent that is general studies related to the effective dispensation of justice which would serve as a data bank to guide the evolution of a meaningful design proposal. The third part which is the Scheme design stage is information as to the design proposal which include 1. Design concepts ii. Appraisal of the design by way of drawings The report is illustrated with diagrams. For the purposes of clear distinction between information on the design and the pre-design information, the first two stages of the study are put together to constitute the first part and the third stage constitutes the part two of the report.

New public management, cocoa swollen shoot virus disease control and farmers opposition: a case study of the Tafo District, Eastern Region, Ghana

This study presents findings on the control of the Cocoa Swollen Shoot Virus Disease (CSSVD) in Ghana. It examines the resistance posed by cocoa farmers to the control of CSSVD through the destruction of diseased cocoa trees. The study’s guiding proposition was that the resistance posed by cocoa farmers to the control of CSSVD could be addressed if a customer-driven approach was used. To explore this proposition, a multiple research method combining interview, Focus Group discussion and policy document analysis was used to gather data. The study was conducted in the Tafo district in the Eastern region of Ghana; the sample consisted of 210 cocoa farmers who participated in semi-structured interviews and 45 respondents who took part in the Focus Group Discussion; and the data obtained was analysed using qualitative and quantitative techniques.The findings indicated that the resistance of the cocoa farmers to the destruction of the diseased cocoa trees was a principal challenge of the CSSVD control in Ghana. The findings also supported that the New Public Management approach to the control of CSSVD will involve the inputs of the cocoa farmers and will therefore reduce their resistance. The study also emphasized the need for education and sensitization of cocoa farmers on issues bothering on the spread and control of CSSVD. The study concluded that to improve the control of CSSVD, a New Public Management approach to the implementation of CSSVD control measures should be adopted to address the issue of resistance by cocoa farmers.

New Variant of SARS-CoV-2 Dynamics with Imperfect Vaccine

)e occurrence of a new strain of SARS-CoV-2 cannot be ruled out. )erefore, this study seeks to investigate the possible effects of a hypothetical imperfect anti-COVID-19 vaccine on the control of not only the first variant of SARS-CoV-2 but also the second (new) variant of SARS-CoV-2. We further examine the rates and a, escape of quarantined infectious individuals from isolation centers. )e control Rc and basic reproduction numbers R0 are computed which gives assess to obtain asymptotic stability of disease-free equilibrium point globally and the existence of a unique persistent equilibrium solution. Numerical results reveal that people infected with the second strain who are vaccinated with an imperfect vaccine are under control but the prevalence of the second variant enhances the prevalence of the first variant. )us, discovering a vaccine that is effective (to a good extent) for the prevention of variant 2 (new variant) is necessary for the control of COVID-19. Numerical results also reveal that increase in the rate at which individuals infected with the first variant escape the isolation center gives rise to the population infected with the first variant and lowers the peak of the population infected with the second variant. )is is probably because individuals infected with the second variant appear to be more careful with their lives and get vaccinated more than individuals infected with the first variant.

Newspaper Distribution as Vehicle Routing Problem

This thesis seeks to address the problem of finding distribution routes from the distribution centre in Kumasi to all the twenty-seven district capitals in Ashanti region for Graphic Communication Group Limited (GCGL) office in the region, not only to ensure timely delivery of newspapers but also cost-effective. The problem was formulated as Capacitated Vehicle Routing Problem with Time Window (CVRPTW) and the Clark and Wright’s Savings algorithm was employed to solve the problem. The algorithm takes the travel time matrix as input and proceeds to find the travel time savings between all the districts. The proposed problem was solved using VRP SOLVER computer program. Comparison of results in terms of the total traveling time obtained by the Clarke and Wright savings algorithm and the actual distribution routes maintained by company showed the current total travelling time can be reduced by up to 21.9%.

The nexus between financial development and economic growth: empirical evidence from Ghana

The study examines the nexus between financial development and economic growth in Ghana over the period 1970-2013. The stationarity test result shows that the order of integration of variables included in the model was a mixture of I(0) and I(1). Therefore the study employs the bounds testing approach to cointegration and error correction models developed within the Autoregressive Distributed Lag (ARDL) framework to explore the long-and short-run effects of financial development on economic growth. The study uses five different measure of financial development including, credit to the private sector, narrow money, broad money, ratio of narrow money to broad money and domestic credit. The study also investigates whether there are other determinants of economic growth. Evidence of both long-run relationship and short-run dynamics was found amongst the various financial development indicators and economic growth. Precisely, the results showed that credit to the private sector, ratio of narrow money to broad money, narrow money, broad money and domestic credit influenced economic growth in the long-and short-run. Again, inflation and government consumption expenditure were found to impede economic growth in the long-run and short-run. Contrarily, capital stock, trade openness and FDI were found to stimulate economic growth both the long-and the short-run. When credit to the private sector was used as an indicator for financial development, financial sector liberalisation was positive. The study recommends that policy makers should take caution in the choice of financial development indicator as a policy instrument for the attainment of growth and development. Again on the basis of empirical evidence, policies to improve the accessibility of affordable credit by the private sector, including small and medium scale enterprises should be enforced.

The Nexus between Government Investment Expenditure and Private Investment in Ghana

This study employs both ARDL model and Granger causality test to examine and test the direction of causality between government investment expenditure and private investment in Ghana for the period 1970 to 2013. The study revealsthat, in both long run and short run, government investment expenditure has an insignificant negative impact on private investment. It is also established that there isa bi-causal relationship between government investment expenditure and private sector investment in Ghana. Based on the bi-causal relationship, the study advocates the need for government to invest more in physical infrastructure and human capital in order to reverse the negative and insignificant effect of government investment expenditure on private investment.

Nexus between job resourcefulness and organizational citizenship behavior in Ghana’s public sector, the mediating role of work engagement.

There have been numerous research works on job resourcefulness and organizational citizenship behaviour against the backdrop of workers in the private sector. However, there is a knowledge gap in similar studies relating to the public sector based on the mediating role played by employee engagement. This study sought to assess the nexus between two distinct public workers (institutions) based on job resourcefulness and organizational citizenship behaviour in Ghana Public Sector looking at the mediating role of work engagement. Questionnaires were administered for 76 workers from both institutions with the use of purposive and availability sampling for the heads and workers respectively based on statistics from Ghana Statistical Service. Regarding OCB, positive work attitude included: workers avoidance of problems among coworkers, adherence to rules and regulations, co-workers work assistance, and responsiveness to information flow or communication. Regarding work engagement, COCOBOD workers had higher response rate than their counterparts at Okomfo Anokye Hospital. The effect is that better engagement means better productivity. Regarding job resourcefulness, Okomfo Anokye Hospital workers had better response rate than their COCOBOD counterparts. The impact of job resourcefulness is to increase customer orientation. Health workers, particularly hospital workers based on their working conditions should be made to enjoy some work benefits as their counterparts in the public sector. The relevance of this study is to bridge the knowledge gap on the subject matter and inform policy-makers on working conditions of public workers.

The nexus of oil consumption, oil price volatility and economic growth in Ghana

The study investigated the nexus of oil consumption, oil price volatility and economic growth in Ghana. Annual time series data sourced from the World Bank’s Development Indicator (WDI) were used in this study, and the series spanned from 1980 to 2013. The ADF test proved all the variables to be stationary after first differencing. The Johansen cointegration test indicated two cointegration equations among the series. The study found a statistically significant positive relationship between crude oil consumption and Ghana’s economic growth, both in the long and in the short run. Crude oil price was found to have a negative relationship with Ghana’s economic growth in the short run, but a positive relationship with Ghana’s economic growth in the long run. The study further found a negative significant relationship between oil price volatility and Ghana’s economic growth in the long run. The study recommends an efficient consumption of crude oil especially in the productive sectors (Manufacturing, Agricultural and Transport sectors) of the economy, in order to stimulate Ghana’s economic growth. And also, to reduce Ghana’s vulnerability to oil price volatility, policy makers must adopt risk management instruments such as physical reserves and hedging against oil prices.

Nighttime nox from sciamachy lunar occultation measurements

Vertical profiles of stratospheric NO2 and NO3 have been retrieved from moderately resolution atmospheric lunar transmission spectra measured by SCIAMACHY (Scanning Imaging Absorption Spectrometer for Atmospheric Chartography) on board the ENVISAT (Environmental Satellite). The measurements were taken over the high Southern latitude (50o S–90o S). The global spectra fitting method by differential optical depth approach were used to fit NO2 and NO3 using the spectral window of 430–460 nm and 615–680 nm respectively. To assess the accuracy of the retrieved NO2 profiles the SCIAMACHY nighttime NO2 profiles were compared with daytime NO2 profiles measured by Halogen Occultation Experiment (HALOE), using photochemical correction model. The validation results show that the quality of SCIAMACHY nighttime NO2 is high within 5–20% in the altitude range of 24–39 km. Our current understanding of NO3 chemistry and the internal consistency of the retrieved NO3 profiles were verified with a complex and a relatively simple model scheme. The complex model uses a comprehensive photochemistry of the stratosphere and the simple model uses only SCIAMACHY ozone and ECMWF temperature and pressure analyses as input. We found that the retrieved NO3 profiles are in very good agreement with the model calculations within the expected accuracy of 20–35 %.
