▼ Fusion of medical images between different cross-sectional modalities is widely used, mostly where functional images are fused with anatomical data. Ultrasound has for some time now been the standard imaging technique used for treatment planning of prostate cancer cases. While this approach is laudable and has yielded some positive results, latest developments have been the integration of images from ultrasound and other modalities such as PET-CT to compliment missing properties of ultrasound images.
This study has sought to enhance diagnosis and treatment of prostate cancers by developing MATLAB algorithms to fuse ultrasound and PET-CT images. The fused ultrasound-PET-CT image has shown to contain improved quality of information than the individual input images. The fused image has the property of reduced uncertainty, increased reliability, robust system performance, and compact representation of information. The objective of co-registering the ultrasound and PET-CT images was achieved by conducting performance evaluation of the ultrasound and PET-CT imaging systems, developing image contrast enhancement algorithm, developing MATLAB image fusion algorithm, and assessing accuracy of the fusion algorithm.
Performance evaluation of the ultrasound brachytherapy system produced satisfactory results in accordance with set tolerances as recommended by AAPM TG 128. Using an ultrasound brachytherapy quality assurance phantom, average axial distance measurement of 10.11 ± 0.11 mm was estimated. Average lateral distance measurements of 10.08 ± 0.07 mm, 20.01 ± 0.06 mm, 29.89 ± 0.03 mm and 39.84 ± 0.37 mm were estimated for the inter-target distances corresponding to 10 mm, 20 mm, 30 mm and 40 mm respectively. Volume accuracy assessment produced measurements of 3.97 cm3, 8.86 cm3 and 20.11 cm3 for known standard volumes of 4 cm3, 9 cm3 and 20 cm3 respectively. Depth of penetration assessment of the ultrasound system produced an estimate of 5.37 ± 0.02 cm, indicating the system’s ability to visualize low contrast objects 5.4 cm into a patient.
PET-CT system’s performance evaluation also produced satisfactory results in accordance with set tolerances as recommended by IAEA Human Health Series 1. Computed tomography laser alignment test ensured that all CT gantry lasers were properly aligned with the patient bed. Image display width test ensured that volume of patient or organ being measured and displayed was equivalent to that selected on the CT scanner console, to a deviation of ± 1 mm. Results from CT image uniformity test showed that mean CT numbers in peripheral regions of interest deviated from the central mean to within recommended tolerance level of ± 5 HU, indicating a good level of uniformity. Computed tomographic dose indices for head and body phantoms were estimated as 44.30 mGy and 20.08 mGy, comparative to console displayed doses of 42.40 mGy and 19.49 mGy respectively. Registration accuracy for PET-CT images was to have displacements of less than 1 mm in x, y and z directions. Image quality of PET-CT images…

▼ The creation of value has long been recognized as a central concept in marketing and has
been suggested as the main purpose of organizations, a key to success via differential
positioning, and a precursor to customer satisfaction and loyalty. Understanding what value
is and how value is created and delivered to customers has become critical especially for
service firms where there is less tangibility. The main aim of this study was to assess the
value creation process of churches – a social institution – through the service experience
created for the patrons of their services i.e. the church members and how personal factors
affect the assessment of customer value.
This study assumed that churches first create positive service experiences through the
deployment of their service mix in order to create the needed value for their customers.
However, the assessment of value created out of the service experience is moderated by
personal idiosyncrasies of church members. Data was collected from four categories of
churches in
Ghana through a structured questionnaire. The analysis method included
ANOVA, Exploratory Factor Analysis and Structural Equation Modeling to test the
hypothesized relationships.
The study identified five elements of church service mix whose deployment influence the
creation of church service experience. The study found no relationship between church
service mix and customer value; but found a positive relationship between church service
experience and customer value. It was also found that members’ personal goals negatively
influence church service experience and customer value creation relationship; while
members’ value for fellowship positively influence church service experience and customer
value creation relationship.
Thus study has contributed to the understanding of value creation and customer experience
within churches, a dominant and non-profit making sector in the Ghanaian economy. The
study has also made some major recommendations to guide future research and church
management.

▼ Micro and small enterprises play a significant role in the socio-economic development of many
countries over the world. In
Ghana, the bulk of these enterprises are in the informal sector
providing employment and income, especially for the poorest members of society. Using data
from the EGC/ISSER survey in 2009/10, the study employed a probit regression model in
examining the determinants of individual participation in the non-farm sector and then estimated
the intensity of participation using a truncated regression model. In examining the effects of
firm-specific and non-firm factors on the financial performance of enterprises, the study
employed quantile regressions.The study used the Sharpe Ratio in adjusting for risks in
comparing the financial performance of male-owned and-female-owned enterprises. The results
indicate that individual and household factors such as gender,household head, spouse of the
household head, formal education, age, size of landholding,access to credit, electricity and
mobile phones shaped the participation of the individual in non-farm self-employment and wage-
employment. Enterprises located in the Savannah and Forest zones were less likely to participate
in non-farm self-and wage-employment as compared to those located in the Coastal zone.The
study found that firm-specific resources dominated market/industry factors in explaining
enterprise financial performance. When risks are not adjusted for, female-owned enterprises
underperform male-owned ones and when risks are adjusted for, women performed no
differently from men. The study recommends technical education and formal registration of
enterprises. The study recommends that deliberate policies should focus on addressing critical
factors such as access to credit, mobile phone, electricity and education, which could serve as
constraints to participation in the non-farm sector. The study also recommends a reorientation of
the mindset regarding female-underperformance hypothesis.

▼ A key issue worthy of academic attention in the study of the Muslim experience in the postindependence
Ghana is the proliferation of new religious movements. These new religious
movements found their way in
Ghana in consequence of Ghana’s diplomatic relations with
some Islamic states such as Egypt and Libya from North Africa, the Kingdom of Saudi
Arabia and the Islamic Republic of Iran from the Middle East. For the first time. Muslims in
the post-independence
Ghana came in touch with new Islamic orientations driven by the
interests of the sponsoring Islamic states to serve their religio-political agenda. Some of these
Islamic movements include Wahhabiyya (Ahlus-Sunnah), Shi’ah and the Green Book of the
Third Universal Theory (TUT).
The dissertation explores how these Muslim states through their embassies promoted their
religio-political interest in the modem day
Ghana. While the representative of these Muslim
states (embassies) promoted the interests of Ghanaian Muslims on education, health,
agriculture, Islamic centers and women empowerment, they in effect introduced their
ideological interest in Muslim religious space in
Ghana. We also examine the activities of the
various quasi-state institutions and the affiliated NGOs to these Islamic states. The study
further explores the extent to which these new religious ideas co-exist with the pre-colonial
and the colonial Islamic movements such as the Tijaniyya in contemporary time.
Significantly, Muslims transnational contacts in
Ghana extend to the United States of
America, in the aftermath of 9/11. Interestingly, this interaction with the West was largely
driven by the interests of the United States government to educate Muslims globally on the
menace of religious terrorism. The dissertation further examines this phenomenon

▼ Giardiasis and cryptosporidiosis remain as part of the commonest gastroenteritis in
Ghana.
The diseases are caused by the protozoan parasites, Giardia lamblia and Cryptosporidium sp.
respectively. Inadequate supply of treated water and poor sanitation are some of the key
factors leading to the spread of these infections. Being zoonotic diseases, it is suspected that,
a large proportion of human infections could come from infected domestic and farm animals.
Though, use of molecular tools has helped to understand how the diseases spread in humans,
animals, and the environment, very little information is available on the epidemiology and
transmission routes of G. lamblia and Cryptosporidium sp. in
Ghana, and a genetic
characterization of the parasite has also not been thoroughly investigated. Information on
clinical manifestations of Giardia infections and co-infections with other diarrhoeal causing
agents particularly rotavirus remain scanty. In the present study, the epidemiology and
molecular characterization of the two parasitic infections were investigated. The study, a
prospective cross-sectional hospital and community-based, was conducted in Accra,
Ghana.
A total of 485 patients comprising of 365 diarrhoeic and 120 non-diarrhoeic children of age ≤
5 years, were studied. Stool samples were tested microscopically, and by enzyme
immunoassay kits. Positive samples were tested by the semi- nested polymerase chain
reaction (PCR) and subsequently characterized into genotypes by PCR-RFLP, and nucleotide
sequence analysis. Demographic and clinical data were obtained by a structured
questionnaire.
In the hospital-based study, prevalence rates of 5.8% and 22.0% were
observed for G. lamblia and Cryptosporidium sp. infections respectively, and prevalence in
diarrhoeic children was significantly higher than non-diarrhoeic children (P< 0.0001).
Infection in day care centres was 10.1% for G. lamblia and 4.2% for Cryptosporidium.
Neither gender nor breastfeeding habits, education level of mother, presence of domestic
animals, source of children’s food, seasons (dry or rainy) was a risk factor for infections of
the two parasites. However, age and source of drinking water were identified as associated
risk factors for infection. G. lamblia genotype B and Cryptosporidium parvum were
identified in the genotyping study. Although severity of rotaviral diarrhoea was reduced by
Giardia co-infection, the results cannot be conclusive. Although both parasites were present
in the studied population, cryptosporidial diarrhoea appears to be more common than giardial
diarrhoea. The presence of infections among non-diarrhoeal children is of much concern, as
they can spread infections unknowingly. The presence of genotype B as the only prevailing
genotype of G. lamblia indicates that infections from animals will be uncommon, but
Cryptosporidium parvum transmission could be either anthroponotic or zoonotic. The co-
infection study had a limitatio n, and therefore demands further investigation. Several

▼ Bats are reservoirs for many emerging zoonotic RNA viruses, including rabies virus (RABV), SARS-like coronavirus, henipaviruses and filoviruses. Several bat species have been associated with Lagos bat virus (LBV) infection. They include Wahlberg‟s epauletted fruit bat (Epomorphorus wahlbergi), the straw-colored fruit bat (Eidolon helvum), the Egyptian fruit bat (Rousettus aegyptiacus), and an insectivorous bat, the Gambian slit-faced bat (Nycteris gambiensis). Bats are important for the maintenance and transmission of zoonotic viruses. The role of bats in the maintenance and evolution of lyssaviruses is complex and poorly understood. Fruit eating bats, including E. helvum, often inhabit and feed in agricultural areas, and this brings them into closer contact with humans and domesticated animals. LBV and other non-rabies lyssaviruses have not been well studied and the risk for humans and animals in
Ghana is uncertain. Lyssavirus epidemiology is influenced by the host species distribution, abundance, demographics, behavioral ecology, dispersal, and interactions with humans. E. helvum occur in cities and rural areas of
Ghana. The species is comestible and hugely harvested for bushmeat by both urban and rural folk. E. helvum feeds on fruits from farm plantations and roosts within or near residential areas. The species thus has close interaction with people. The pathobiology and route of transmission of LBV is not known in E. helvum bats. This study is one of the few studies of LBV in fruit bats in
Ghana and the experimental infection study is the first conducted on LBV in one of its natural reservoir species. Using E. helvum as a model, we hypothesize that there is endemic circulation of LBV in this bat species in
Ghana. The circulation of Lagos bat virus in the bat population is facilitated by certain pathobiology of the infection including susceptibility to the virus, incubation and clinical periods for different doses and routes of LBV infection, behavioral changes of rabid bats, virus occurrence in various bat tissues and excreta. Inoculation of LBV will result in clinical disease (rabies), although not all inoculated bats will develop the disease, especially when inoculated peripherally. The aim of this PhD study was dual. Firstly, it investigated infection dynamics of LBV in E. helvum in free ranging populations at the 37-Military hospital in Accra and Tano Sacred grove and in a captive population of E. helvum kept at the Achimota Forest. Secondly, the study conducted experimental investigation of the pathogenesis of Lagos bat virus, in E. helvum in captivity at the Achimota Forest in Accra,
Ghana. To evaluate these hypotheses, E. helvum bats were repeatedly sampled from two major roost locations in
Ghana from 2012 - 2014. Longitudinal sampling was also undertaken quarterly on captive bats at the Achimota Forest. Dead bats were collected from the roost sites and predetermined tissues collected at necropsy. Serum samples were subjected to virus neutralization tests against LBV. Tissues from dead bats were tested by…

▼ Highly active antiretroviral therapy (HAART) is known to improve treatment in Human
Immunodeficiency Virus (HIV)-infected patients but the emergence of drug resistance is an
obstacle in the effective management of HIV infection and Acquired Immune Deficiency
Syndrome (AIDS). Plasma viral load monitoring is the gold standard used in high-income
countries for monitoring treatment but it is not available in many resource-limited settings.
Although limited viral load testing is now available in
Ghana, viral load is not routinely used
for monitoring majority of patients on HAART. Physicians in
Ghana therefore depend mainly
on CD4 counts and clinical symptoms to monitor treatment. Thus, a significant proportion of
patients may suffer virologic failure while continuing to take first-line antiretroviral therapy
(ART). This may encourage the development and accumulation of drug resistance mutations
and compromise future treatment efforts.
The aim of this study was to investigate the presence of HIV drug resistance mutations in
patients on ART in
Ghana, relate these mutations to treatment regimens in order to inform
policy on ART monitoring and patient management in the country.
Venous blood was obtained from 338 patients on ART from the Korle-Bu Teaching, St.
Martin de Porres, Atua Government and Kumasi South hospitals in
Ghana. Personal
information and ART history of the patients were also collected using a sample collection
form. The CD4 counts and viral loads of patients were determined. HIV ribonucleic acid
(RNA) and proviral deoxyribonucleic acid (DNA) were extracted from the plasma and
peripheral blood mononuclear cells (PBMC), respectively. The HIV protease and reverse
transcriptase genes were amplified from the RNA and DNA by polymerase chain reaction.
The positive amplification products were sequenced and analyzed for drug resistant mutations
using the Stanford HIV Drug Resistance Database.
The mean age of patients was 42 years and 72% of patients were female. The mean CD4
counts increased from 161cells/μl at start of therapy to 454cells/μl at time of sampling. Only
7% of patients had detectable viral loads at time of sampling. Most of the patients (87%) were
on first-line regimen. Physicians rating showed that 86% of patients were doing well and the
rest were either not doing so well (11%) or were failing (3%). The reverse transcriptase gene
was successfully sequenced from 65 (19%) and 99 (29%) of plasma and PBMC respectively
while protease gene was successfully sequenced from 54 (16%) of plasma and 76 (23%) of
PBMC. Out of these, 46 % and 49% of the plasma sequences had nucleoside reverse
transcriptase inhibitor (NRTI) and non-nucleoside reverse transcriptase inhibitor (NNRTI)
resistance mutations respectively. From PBMC, 25% and 26%, respectively had NRTI and
NNRTI mutations. Protease inhibitor (PI) resistance mutations were found in 28% of plasma
and 9% of PBMC sequences. The most common NRTI mutation found was M184V and that
of NNRTI was K103N. Thymidine analogue mutations…

▼ Kenkey, is a maize based sour, stiff dumpling, and it is among the most common fermented
cereal food products in
Ghana. There are several types of kenkey, and while some are made
from whole maize grains others are produced using degermed/and dehulled maize grains.
The kenkey types made using dehulled maize grains are less popular and have largely
remained at the level of “ethnic food”, restricted to very few socio-cultural communities.
Current trends in urbanization, and the increasing popularity of kenkey among consumers,
require larger scale production with consistent quality. The study was carried out to
examine the traditional white kenkey process and to optimize the key processing variables
in order to obtain reproducible quality white kenkey that will be acceptable to native and
non-native consumers.
A survey was conducted in three white kenkey production districts to collate information
on production, vending and consumption practices. The sensory profile and consumer
acceptance of different types of kenkey and other fermented maize products in
Ghana were
investigated. A total of two hundred consumers including 110 Ghanaians and 90
internationals were used for the consumer test. Traditional white kenkey types were
analyzed for their physicochemical, textural, microstructure and sensory characteristics.
Physicochemical analysis involved determination of pH, titratable acidity, sugars, lactic
acids, minerals, vitamins and amino acids using high performance liquid chromatography
procedures. The textural characteristics of white kenkey randomly obtained from traditional
processors were determined using instrumental (texture analyser) and consumer
assessments.
The effects of processing variables of steeping time (12, 30 and 48 h) and dough
fermentation time (0, 12 and 24 h) on the physicochemical properties of white kenkey were determined. A (three variable) Box-Behnken design was used to optimize the processing
variables of steeping time, steeping temperature, and fermentation time on white kenkey
quality parameters of moisture, pH, titratable acidity, glucose and lactic acid content. The
optimum region of the process variables was obtained by hedonic tests on the white kenkey
using balanced incomplete block design (for k= 5, b= 21, λ=2, r =7)
Quantitative Descriptive Analysis (QDA) was conducted on white kenkey made from
within and outside the optimum region of the process variables, as well as white kenkey
obtained from vendors using a panel of 18 trained members. Consumer acceptance study
was conducted using 65 consumers for white kenkey obtained from the optimum region
and traditionally processed white kenkey obtained from vendors.
The results of the survey showed that there were two main types of white kenkey, nonsweetened
white kenkey and sweetened white kenkey to which sugar is added during
production. All three procedures involved steeping of dehulled maize grains which is then
milled into a meal. In the (procedure at Atimpoku), the meal was not fermented any
further but…

▼ What did Ghanaian Women do with Radio, for what purposes and to what ends? Combining scholarship from gender and colonialism with media theories, archival research (written and audio), and oral history, this study on Women’s Radio history explores Ghanaian Women’s relationships with Radio, “an important Imperialist asset” involved in the mission of “civilising” primitive Africans and empire-building. The overarching theoretical foundation for the study is modernisation, packaged as Victorian styled “domesticity” a framework for British cultural imperialism. The study argues that women across various levels of social and cultural power, appropriated Radio and transformed it into a resource to contest their subordination, to expand their communication space and to negotiate new and more equitable gendered relationship within a predominantly patriarchal domestic space. In support of the thesis, the study examines three areas of women’s relationship with radio. Firstly, it explores the employment trajectory of women in radio careers focusing on the pioneers and key personalities and their contribution to the development of radio in
Ghana. Secondly, it unearths the neglected history of Women’s Radio Programmes and shows how post-colonial Ghanaian women used the programme space to subvert colonial and neo-colonial agenda of promoting Victorian-styled domesticity and separate women’s sphere. Thirdly, the study examines the history of women’s listening relationship with radio. Findings from the study indicate that by taking up careers in radio, Ghanaian women transcended historical prejudices against women in the exclusively male-defined economic space of Radio Broadcasting to contribute to the development of radio. In their roles as programme producers, journalists, and programme makers, Ghanaian women were agents in the early construction of national unity and the grander agenda of African Unity. The study also found that Ghanaian women had a strong voice on radio using the Women’s Radio Magazine spaces strategically to advocate women’s rights; to educate women on many issues peculiar to their sex and on national issues of health, hygiene, economics, science, sports and patriotism. As radio listeners, post-colonial Ghanaian women were not passive to radio programmes but selective of the programmes they listened to and engaged with content to facilitate their “personal modernity” and integration into “modern society.” This study presents new evidence that aside propaganda, radio was a primary tool of domesticity from the early 1930s. It also addresses critical historical issues regarding the use of radio to propagate Victorian domesticity in post-colonial
Ghana particularly after independence. The study rejects the notion that domesticity was a negative feature of post-colonial Ghanaian women’s life and argues that post-colonial Ghanaian women appropriated radio, a domestic technology and a tool of domesticity and transformed it into a resource to foster their integration into “modern society.”

▼ Background: Yaws is a treponemal infection that was almost eradicated fifty years ago has re-emerged in a number of countries including
Ghana. Single dose intramuscular benzathine benzylpenicillin was the recommended treatment. However treatment by intramuscular injection poses several operational and logistical constraints in poor communities where yaws occurs. Results of a randomized clinical trial in Tanzania showed that azithromycin was effective against syphilis a venereal treponemal infection, however little is known about its effect on yaws. This study describes the epidemiological characteristics of yaws including its prevalence and risk factors, and compares the efficacy of a single dose oral azithromycin as an alternative to intramuscular benzathine benzylpenicillin for the treatment of yaws in three selected yaws endemic districts in Southern
Ghana namely: Awutu Senya, Ga South and West Akim districts.
Methods: To describe the epidemiology of yaws we conducted a cross sectional survey that described the prevalence of the disease among various socio-demographic groups in the study area, and a case control study to determine various risk factors associated with the disease. In the clinical trial we set out to test the hypothesis that azithromycin was inferior to injection benzathine benzylpenicillin by 10% in the treatment of yaws. We conducted an open-label, randomized non-inferiority trial in the three selected yaws endemic districts. Children aged
1-15 with yaws lesions were assigned to receive either 30mg/kg of oral azithromycin or benzathine benzylpenicillin at a dosage of 0.6 million units for children below 10 years and 1.2 million units for those 10 years and above. The primary end point was clinical cure rate, defined as a complete or partial resolution of lesions 3 weeks after treatment. The secondary endpoint was serological cure, defined as at least a four-fold decline in baseline RPR titre 6 months after treatment. Non- inferiority of azithromycin was determined if the upper bound limit of a 2 sided 95% CI was less than 10%.
The trial was registered with Pan African Clinical Trials Registry number PACTR 2013030005181.
Results: The overall prevalence of yaws in the study area was 1.95%; however district prevalence ranged from 0.96% in the West Akim district to 2.77% in the Awutu Senya district. Yaws prevalence among female participants was 1.76% compared to 2.05% among male participants. Participants below 5 years had the lowest prevalence of 1.77%; the age group with the highest prevalence of 2.02% was 11-15 years. Results of the univariate analysis showed several risk factors associated with yaws: Males were 1.8 times more likely to have yaws compared to females (OR: 1.8, CI: 1.0-3.2, p-value=0.032). Persons who do not bath daily were 3 times more likely to have yaws compared to those who bathed daily, (OR=3.0, CI: 1. 0-5.4, p-value=0.000). The results also showed that persons living in a compound house were 1.8 times more likely to have the disease compared to those who lived in single…

▼ The sedimentary record, as revealed in sediment cores, can be used to reconstruct the past history of contaminant input into the aquatic environment. This is because contaminant inputs equilibrate rapidly with sediment supply, and the sediment column represents a continuous sequence of sediments that are associated with contaminant accumulation. With radiometric techniques, it is possible to date recent sediments over a period corresponding to about five half-lives (approximately 100-200 years using 210Pb). To understand the geochemistry of estuarine sediments in relation to their provenance, trace metal accumulation trends and potential ecotoxicological risks, this study investigated sediment cores and surficial sediments from the Ankobra, Pra, Amisa, Densu, Sakumo II and Volta estuaries of
Ghana. Geochemical and petrographical techniques were used to reveal the source of sediment supply into the estuarine environments. In addition, Gamma Spectroscopy and Inductively Coupled Plasma Mass Spectrometric (ICP-MS) techniques were used for deriving geochronologies, sedimentation rates, spatial and temporal accumulation of Mo, Cd, Pb, V, Cr, Cu, Zn, As and Hg in the study sites. The pollution status of the estuarine sediments was investigated using Aluminum-normalized enrichment factors (EFs). Cluster and correlation analysis differentiated natural from anthropogenic sources of trace metal in the estuaries. The excess fluxes of trace metals, estimated using sedimentation rates helped in quantifying the extent of anthropogenic contamination of metals in each estuary. AQUARISK software was used to assess any potential ecotoxicological risks associated with trace metal enrichments. Results showed that sediments from the Ankobra, Pra, Densu and Volta estuaries comprised quartzose sedimentary provenance while those of Amisa and Sakumo II estuaries comprised mafic igneous provenance. The sedimentation rates estimated from the constant rate of supply model were 0.24±0.10 gcm-2y-1, 0.47±0.20 gcm-2y-1, 0.43±0.02 gcm-2y-1, 0.31±0.13
gcm-2y-1, 0.20±0.01gcm-2y-1 and 0.54±03 gcm-2y-1 for the Ankobra, Pra, Amisa, Densu, Sakumo II and Volta estuaries respectively. The sediment core from the Ankobra estuary was significantly enriched with Hg (5.0<EF≤8.4) and extremely enriched with As (69.3<EF≤114.3) over time. Similarly, the sediment core from the Pra estuary showed significant enrichment with Hg (5.0<EF≤10.2) between 1980 AD and 1995 AD and very high enrichment with As (EFs around 20.5) since 1875 AD to present. Likewise, the sediment core from the Amisa estuary showed significant enrichment with Hg (EF=6.3) around 1940 AD and a significant enrichment with As (5.0<EF≤6.5) from 1960 AD to present. On the contrary, the sediment core from the Densu estuary was not enrichment with trace metals although a sharp peak correlating to a moderate EF of 4 was observed around 1965 AD for Hg. The sediment core from the Sakumo II estuary was significantly enriched with Hg (5.0<EF≤6.3) since 2005 AD to present, with other trace metals showing…

▼ The inclusion of an additional safety rod in conjunction with a core conversion study of
Ghana Research Reactor-1 (GHARR-1) was carried out using neutronics, thermal hydraulics and burnup codes. The study is based on a recommendation by Integrated Safety Assessment for Research Reactors (INSARR) mission to incorporate a safety rod to the reactor safety system as well as the need to replace the reactor fuel with LEU. Conversion from one fuel type to another requires a complete re-evaluation of the safety analysis. Changes to the reactivity worth, shutdown margin, power density and material properties must be taken into account, and appropriate modifications made. Neutronics analysis including burnup was studied followed by thermal hydraulics analyses which comprise steady state and transients. Four computer codes were used for the analysis; MCNP, REBUS, PLTEMP and PARET. The neutronics analysis revealed that the LEU core must be operated at 34 kW in order to attain the flux of 1.0E12 n/cm2.s as the nominal flux of the HEU core. The auxiliary safety rod placed at a modified irradiation site gives a better worth than the cadmium capsules. For core excess reactivity of 4 mk, 348 fuel pins would be appropriate for the GHARR-1 LEU core. Results indicate that flux level of 1.0E12 n/cm2.s in the inner irradiation channels will not be compromised, if the power of the LEU core is increased to 34 kW. The GHARR-1 core using LEU-UO2-12.5% fuel can be operated for 23 shim cycles, with cycle length 2.5 years, for over 57 years at the 17 kW power level. All 23 LEU cycles meet the ~ 4.0 mk excess reactivity required at the beginning of cycle. For comparison, the MNSR HEU reference core can also be operated for 23 shim cycles, but with a cycle length of 2.0 years for just over 46 years at the 15.0 kW power
level. It is observed that the GHARR-1 core with LEU UO2 fuel enriched to 12.5% and a power level of 34 kW can be operated ~25% longer than the current HEU core operated at 30 kW. Based on the results presented in this report, it is concluded that the conversion of the GHARR-1 to LEU core is not likely to compromise safety nor increase the frequency/severity of any of the postulated design basis accidents identified in the current approved SAR.

▼ In many cities across the globe, transportation has been a major catalyst for economic growth and for the progress of human societies. However, as an activity that is largely dependent on the combustion of fossil fuels, on-road urban transportation has fast become one of the most important sources of anthropogenic-induced Greenhouse gases (GHGs) which are known to contribute to climate change. The causes and effects as well as adaptation and mitigation strategies for climate change have received global attention from policy and non-policy actors, including the scientific and academic community. Three broad climate mitigation strategies –efficiency in vehicle technologies, use of alternative fuel sources and travel reduction through land use and transport integration –have been proposed for the transport sector. Climate mitigation policy for the transport sector in
Ghana has generally favoured the first two strategies. Thus, notwithstanding the burgeoning scientific evidence that has shown that developing countries have greater opportunities to significantly mitigate climate change through an integrated land use and transport system, the third strategy has not received the needed academic and policy attention. In the context of urban sprawl and long commuting distances between residential areas and locations of activity points in some major Ghanaian cities, this present study explores the ramifications of present land use and transportation systems on energy use and climate mitigation, using the Greater Accra Metropolitan Area (GAMA) as a case study.
Inspired by the philosophical worldview of pragmatism, the study adopted a complementary mixed methods design involving quantitative surveys of trip makers and qualitative interviews with relevant stakeholders, including public transport suppliers, government officials and social scientists, together with participant observations. Secondary data sources, including policy documents and existing literature were also used in the study. The Systems conceptual framework of land use and transport system was developed as an interpretative guide in analysing the symbiotic relationship between spatial and transportation
patterns and the extent to which this relationship has impacted on energy use and GHG emissions in GAMA.
While GAMA continues to sprawl, the functional interactions between Accra Central and its peri-urban localities with respect to work, shop and accessing government services trip patterns are characterised by extensive use of low occupancy motorised transport modes over long commuting distances. This has adverse implications for per capita energy use and GHG emissions. In contrast, relative short distance trips to nearby activity points are accompanied by a significant use of non-motorised transport modes by trip makers with its associated reduction in fossil energy use and subsequent emissions. Long distance trip makers surveyed expressed high preference for mass transit, with its climate mitigation co-benefits.
In the light of the above, it is…

▼ This thesis looks at the socio-economic and psychological factors mediating marital
commitment among married couples in the Taifa Circuit of the Methodist Church
Ghana,
in the Greater Accra Region of
Ghana. Attention was paid to the nature of the socioeconomic and psychological factors that influence marital commitment in the Ghanaian context. Many marriages have suffered difficult situations such as deep regrets by spouses, depression, divorce etc all due to low level of marital commitment.
The methodology for this thesis is quantitative in nature. A survey design was used for
the study. Here the Rev Ministers of the various branches of Methodist Churches in the
Taifa Circuit were interviewed verbally to know their findings concerning the topic under
study. This is because they interact with married couples in the church during
programmes such as family life, marriage counselling, pre-marital counselling, couples
meetings and resolution of marital issues. The research instrument used was
questionnaires namely International Personality Item Poll and, Personal Relation and
Marital Happiness Scale. Five hypotheses were tested and supported by the use of the chisquare. The study investigated the link between personality, marital happiness and
commitment. The link between socio-demographic factors and marital commitment was
also assessed. The results revealed that, in the aggregate more married females show
higher marital commitment level than their male counterparts. It also revealed that a
lower commitment level in marriage was not attributed to respondent’ education. The
analysis showed that those with agreeable personality trait have a higher marital
commitment than those with extraversion personality trait.

▼ Workplace safety and health is a crucial concern for all—wage earners, employers/management
and the society as a whole. This is because workplace injuries and accidents have many
ramifications on the life of the individual worker as well as others in society. Consequently,
countries, as diverse as they are, have put in place mechanisms to ensure the safety of workers
through several administrative, policy and legal instruments. Indeed, today the safety and health
of workers is considered a global human rights issue.
In spite of this, the informal sector that employed the majority of low skilled workers in
developing economies is often neglected in most systematic studies. The informal sector has
attracted less attention not only from government but also from academics, policy researchers
and human rights advocacy groups. In the rare instances where studies are conducted, they tend
to focus on productivity to the neglect of safety.
In Ghana where the informal sector of the economy has outgrown the formal sector, as a
consequence of the Structural Adjustment Programmes (SAP) undertaken in the 1980s, and, the
Highly Indebted but Poor Initiatives (HIPC) in the 2000s, have deregulated and liberalized the
Ghanaian economy and resulted in shrinking the role of the state in job creation. Consequently,
vehicle repairs and spare parts retail have become one of the common features of the informal
economy since many middle-class workers rely on imported vehicles from Europe and the North
America. In spite of the popularity of the vehicle repairs and spare parts business, the physical
environment in which the artisans work, and their occupational health and safety (OHS)
conditions are often absent from intellectual discourse regarding their business activities. As such, this study explored artisans’ experiences with occupational hazards and the coping strategies within their work environment. The study utilised the qualitative in-depth interview and observational methods to understand the general level of safety among the artisans at Kokompe in Accra. The artisans selected for the study included auto-mechanics, autoelectricians, auto-welders, auto sprayers and auto-spare parts dealers made up of master artisans, apprentices and other workers. In all 58 artisans were selected through convenience and snowballing sampling techniques. In addition, six key informants from state inspection agencies and other departments concerned with Occupational Health and Safety (OHS) in Ghana were interviewed. The study revealed that the general level of safety and working conditions among the artisans was poor as all processes—welding, spraying mechanical and other artisanal activities—were carried out at the same place often resulting in multiple exposures to different hazards and safety concerns. The predisposing factors leading to these were human, environmental and mechanical. However, most of the artisans attributed accidents and injuries to unforeseeable events or spiritual forces. Significantly, it was observed that the…

▼ Decades of rapidly growing urban population, the growth of a business and middle class with money to invest, and an expanding private sector with large investment capital and the ability and willingness to pay high prices for property have resulted in rapid commoditisation of land in the Ga State. Concomitant with these are highly insecure land ownership, land litigation and conflict, poor land use planning and enforcement of land laws. Investigating the processes by which communal and statutory lands become difficult to access and tenure insecurity are necessary to determine the potential outcomes of contemporary and future land administration reforms. Specifically, the study investigates the politics of property rights institutions creation and change from 1876 to 2010 in the Ga State in
Ghana. The study‟s methodology was philosophically grounded within the pragmatism paradigm which used a convergent parallel mixed methods research approach. Qualitative and quantitative data collection was concurrently done. Selection criteria for in-depth interviews (30) and FGDs (8) of chiefs, family heads and bureaucrats (30 in all) were based on purposive sampling and „snowballing‟ technique. Quantitative data collection involved a household survey of 323 households in 52 localities in 4 purposively selected traditional areas namely Nungua, Tema, Kpone and Gbawe in the Ga State. Archival data from PRAAD,
Ghana Law Finder Database and Government of
Ghana reports complemented primary data. The Institutional Analysis and Development (IAD) a multi-tier conceptual framework was used to do a systematic analysis of evolving power relations in decision making concerning land administration between the Ghanaian State and the Ga State actors from 1870s to 2010.
Generally, results indicate that in a path-dependent manner, all governments (colonial and post-colonial) used state hegemony to impose land rules on Ga land owners and society. A general lack of cooperation and inadequate information characterized the relationships between governments‟ actors and the Ga chiefs and people. Such interactions and high levels of distrust among Ga chiefs, family land owners and individuals resulted in declining trusteeship ideals of Ga land tenure. Speculation in land, wanton land sales, land conflicts and chieftaincy disputes, landlessness, demolition of property and loss of life due to land litigation therefore remain still prevalent in the Ga State. Hence, despite comprehensive interventions such as LAP I, access to land and tenure security remains an acute challenge within the Ga State as some communities and social classes face dire situations of land tenure insecurity. LAP I was poorly conceived and implemented. Set targets for LAP I were hardly achieved- high transaction cost in resource allocation, customary boundary demarcation fiasco and only 8000 out of 50,000 land title certificates were issued in Accra and Kumasi. Self-interested politicians and bureaucrats maximized LAP I budgets and protected their parochial interests for top…

▼ One of the hallmarks of our rapidly evolving democratic culture as a nation has been the
relentlessness with which we have subjected every social institution to scrutiny through
open debate and discussion. Consistent with this culture of debate, there has been a flurry
of criticisms and commentaries about the institution of Chieftaincy. Not surprisingly, no
consensus on the relevance of the institution in the midst of a modern nation-state has so
far been achieved.
One side of the debate suggests that the institution is incompatible with modern forms of
governance and must therefore be discarded. And, almost invariably, those who suggest that
Chieftaincy should be abolished argue that the institution is hereditary and therefore
undemocratic. The argument also runs that the institution has lost much of its original
functions and that it fosters tribalism, conflict and classism, so to speak.
The polar view asserts that traditional institutions are indispensable for political
transformation in the country, as they represent a major part of the country’s history,
culture, and governance system. This view favours the continued existence of chieftaincy
because the institution is seen as playing key roles in the socio-political lives of the people.
It is significant to note that juxtaposed with this chieftaincy institution is the sometimes
parallel “modern State”, vested with enormous authority in rule making, application,
adjudication and enforcement; thus creating political dualism in the country. This dualism
transcends all levels – national, regional, district and village level politics – under the
present Fourth Republic of
Ghana.
The issues have been, do these political institutions exist and function together or in
isolation? Are there not interrelations between them? If there are, what are the nature and
dynamics of the interrelations between these two separate leaderships as they exist and
function alongside each other?
Within the theoretical perspective of the interplay of tradition and modernity as it happens in
every social change, this study looks at the possible diverse relations between the traditional
rule and local government structures in some small communities (Apapam and Nkronso) in
Akyem Abuakwa, with emphasis on the controversy over the relevance of chieftaincy to
mainstream politics at the local level. In this regard, the broad objective of the investigation
is to examine how the chieftaincy institution and local government in Akyem Abuakwa
local communities co-exist and function alongside each other in spearheading socio-
economic activities, and maintaining law and order. An additional objective is to assess the
issue of whether or not traditional rule has lost its relevance and importance after the
establishment of local government under the Fourth Republic of
Ghana.
Field data were collected from three categories of respondents: traditional leaders,
government functionaries and the people (the ruled). Four main instruments were used,
namely, interviewing (of…

▼ Shoreline change is an issue of concern to most coastal managers because the coastal zone is home to over 60% of the world’s population. In
Ghana, shoreline change has been associated with loss of economic lands and properties. Previous researches have shown that the
Ghana coastline is eroding at variable rates; the Eastern and Central Zones are receding while the Western zone is thought of as stable. This opinion, however, contrasts field observations and interview with local coastal community members. This research therefore sought to determine the shoreline change trends in the study area through modelling the driving and resistive factors along the shores. The factors investigated are sea-level rise, wave impact, sediment supplied by rivers, resistance of coastal material and human impact. Multi-temporal spatial datasets, hydrodynamic datasets, geological map of the area and systematically sampled field measurements were used. Standard procedures were employed to compute values for the eight variables that were selected as proxies for the driving and resistive variables. Analysis was carried out in short-term (1974-2005) and long-term (1895-2005) change categories in shoreline trends. Average short term change rate of -4.18 ± 0.10 m/year and long term change rate of -7.25 ± 0.11 m/year were obtained for the entire study area. The results revealed that the strength of hard shore outcrops, the shear strength of the soil, the sediment supplied by rivers and human impact contributed significantly to variations in the shoreline change trends along the study area. It was identified that shoreline change trends observed in the study area is mainly caused by physical processes of wave action, which is modified by the characteristic features along the shores, and aggravated by human impact. The shoreline change trends reflect the coastal material resistance at the various sections along the coastline; this is attributed largely to the formation history of the coast. It was, however, found out that the effect of sea level rise on the shoreline trends was minimal. The Western Section of the study area was found to be more vulnerable to erosive forces relative to the Eastern Section. It is recommended that a non-linear model be employed for confirmation of the findings.

▼ Demand Responsive Approach (DRA), adopted as a policy for rural water delivery in
Ghana, is an attempt within a decentralized programme to improve the efficiency of
service supply and also to make users take key decisions about the service they want
and are willing and able to pay for. This study was conducted in communities where
the DRA had been applied under the National Community Water and Sanitation
Programme (NCWSP) in the Shai-Osudoku District of
Ghana. The aim was to
examine the conditions under which DRA leads to improved functionality, the
suitability of the approach for rural communities and the changes in the patterns of
water usage. Data was collected using purposive sampling from two hundred
households in four communities in addition to FGDs and key informant interviews.
Descriptive statistics and probit regression was used to determine the socioeconomic
factors influencing households’ ability to pay for water and factors which affected the
use of water. The study established among other findings that community members
participated in the implementation of the facilities in various aspects: an expression of
demand. Respondents indicated the water facilities were of good quality in terms of
durability, flow and taste; however, financial management is a major setback.
Generally the water needs of the communities are met. It was also realised
households which were closer to the facilities in general used more of the water from
the facilities. The study recommends an institutional coordination and collaboration
among stakeholders, education and training for committee members, equity concerns
should be addressed and external support to be factored in rural water delivery.

▼ Niger’s rice production has not been able to match growth in demand. The slow growth in domestic rice production has been attributed to salinity, non-adapted germplasm, and low farmer adoption of improved varieties. This study was carried out to: determine farmers’ perception on influence of salinity in rice production and their preference for rice varieties in salt affected areas; identify potential sources of genes for salt tolerance from local and exotic rice germplasm; determine genetic control of salt tolerance in rice; and evaluate yield performance of early segregating generations of rice from crossing diverse parental genotypes.
Participatory rural appraisal (PRA) was conducted in three regions of Niger involving 197 farmers from 11 villages. The results showed that rice is the most preferred crop. Farmers identified lack of fertilizer, diseases, salinity, and lack of good varieties as the main production constraints. Ninety (90) percent of the farmers were aware of salinity problem and use manure and/or ashes, straw, and the avoidance of urea as coping strategies. The farmers preferred high yielding rice varieties with tolerance to diseases and salinity, medium height and high tillering ability.
Laboratory analyses were carried out on soils from irrigated and non-irrigated fields as well as irrigation water. Most of the irrigated rice fields were clayey (40 to 50% clay). The non-irrigated ones were mostly sandy (50 to 90% of sand). The irrigated soils were characterized by pH which varied from 3.2 to 6.8, an electrical conductivity (EC) above 4, a sodium adsorption ratio (SAR) below 13 and an exchangeable sodium percentage (ESP) below 15. The water analysis indicated the sodium adsorption ration (SAR), the potassium adsorption ration (PAR) the total dissolved solids (TDS), and sodium content of irrigation water varied from site to site. The total sodium quantity estimated to be deposited per hectare per year varied from 87 kg/ha/year to 218 kg/ha/year.
Fifteen exotic and five local varieties were evaluated in a greenhouse under four salt levels and a control without salt. Significant genotype by salt concentration effect was observed. Significant variability among varieties (probability level of 0.001) across and within salt levels was present for all the traits measured. Four salt tolerant genotypes with high selection index were identified.
One hundred and twenty F3 families derived from a diallel cross of 4 parents were evaluated in salt affected farmer’s fields in two sites. High heritability was observed for almost all the traits. Additive effects for tiller number, panicle number, and panicle weight, additive maternal effects, and partial dominance effects for height and duration were observed. Yield potential varied significantly (Probability level of 0.001) among F3 families ranging from 2.52 to 4.17 t/ha. Correlation analysis among traits showed that yield was significantly and positively associated with height, tiller and panicle number, and panicle weight.

▼ In the pursuit to improve man’s livelihood, human activities which include emission of heavy metals from various industries and sectors, as well as the past use of chemicals such as pesticides, polychlorinated biphenyls and flame retardants have often mobilized and redistributed natural substances and anthropogenic pollutants into the atmosphere, predisposing it to relatively high concentrations of such pollutants even in pristine areas in the environment.
This study assessed the level of atmospheric pollution, contributing sources and human health exposure risk of persistent organic pollutants (POPs) along with selected heavy metals with focus on Abetifi, one of the highest altitude environments in Ghana. Passive sampling with polyurethane foam (PUF) as adsorbent was employed. Samplers were deployed every 84 days for two years. A total of 65 polyurethane foams were deployed and twelve (12) groups of analytes were considered together with their various isomers. High resolution gas chromatographic technique coupled with high resolution mass spectrometry (HRGC-HRMS) and electron capture detectors (ECD) were used in the analysis of the POPs. Besides, high performance liquid chromatography (HPLC) coupled with MS was employed in analysing the perfluorinated compounds (PFCs) while the heavy metals were analysed using Atomic Absorption Spectrometer (AAS). Principal Component Analysis (PCA) and UNMIX model were used to group pollution source contribution of all analytes (POPs and heavy metals) in this study. Diagnostic isomer and other predictive ratios were also employed for source apportionment of various individual analyte groups.
Results revealed that polychlorinated dibenzo-furans gave with the least total mean concentration (0.074 pg/m3) for the sampling period and polybrominated biphenyls gave the highest (55 pg/m3). The pesticide group gave values in the order of DRINs (53 pg/m3) > DDT (41 pg/m3) > HCHs (28 pg/m3). Data for perflourinated compounds (PFCs) in the atmosphere at Abetifi was recorded with a maximum total concentration (Σ8) of 15 pg/m3. The human exposure level to dioxin-like chemicals in the air at the study location was 0.0067 pg TEQ/kg bw per day. The atmospheric pollution source observed at Abetifi was a mixed one consisting of agricultural, vehicular and from burning of biomass. Agricultural source was basically as a result of re-volatilization from polluted sinks (a secondary pollution source).

▼ This research examines the rationale behind the institutionalized pilgrim-age process of the Methodist Church
Ghana (a phenomenon, dubbed Sacred Site Visitation in this research), and its relationship with the renewal program of the Church. The study was approached from an interdisciplinary perspective, namely, theological, church historical and anthropological perspectives to demonstrate how sacred site visitation affects renewal. Victor Turner’s theory of Communitas constituted the theoretical foundation of the study. The theory perceives sacred site visitation as a liminal phenomenon, characterized by Communitas, a situation which offers opportunities for ‘pilgrims’ to enjoy a fresh kind of social existence of harmony, filial bond and freedom in their spiritual quest.
Adopting a qualitative approach to data management, interview schedules, focus group discussions were employed to elicit views, beliefs, and insights from the Church’s clergy and the laity about the Church’s practice of sacred site visita-tion. Three prayer centres of the Methodist Church,
Ghana, were used for case study with purposive samples of the laity, youth and senior hierarchy constituting the respondents. Two viewpoints emerged from the study. On one hand, sacred site visitation is a means of spiritual renewal in the Methodist Church
Ghana for the following reasons: providing church members with the opportunity to enhance their prayer lives; satisfying physical, spiritual and emotional needs. It also helps the Church to construct a firm and non-negotiable image of the Wesleyan tradition. On the other hand, it emerged that renewal in the Church goes beyond sacred site visitation, fasting or praying to a holistic development of Church members. Whereas the Church hierarchy was associated with the latter viewpoint, the laity
held on to the former viewpoint. A remarkable finding was that the laity’s per-spectives on certain sacred site visitation practices ran contrary to the Church hi-erarchy’s perspectives. The recommendations from the research were two-fold: for academia and the Methodist Church
Ghana. For academia, it is recommended that there should evolve a discipline, Hierotopy or Hierotopical Studies under the Hu-manities which transcends the methodological and terminological limitations im-posed by traditional humanistic disciplines. For the Church, various steps should be made to streamline sacred site visitation to meet the qualitative growth of the members of the church.

▼ This study was conducted in the Northern guinea and Sudan savannas of Zaria and Kano, Nigeria to: (i) identify cowpea production constraints and assess farmer and consumer perceptions and preferences on grain quality traits in cowpea, (ii) assess the variability of grain nutritional values (protein, iron and zinc contents) of cowpea accessions from Africa and other parts of the world, (iii) determine the mode of inheritance of iron and zinc contents in cowpea grains and (iv) determine the relationship between zinc concentration and yield components. Farmers pointed out inadequate improved cowpea seed at planting time (rainy season) and lack of resistant varieties to pod sucking and pod boring insects as the major constraints to cowpea production in the areas. Farmers preferred a cowpea variety that combines high yield with rough texture, white or brown colour. Consumers‘ grain quality preferences were consistent with those of farmers, except for women who prioritized cooking time and oil consumption. Significant genetic variations were observed in: zinc content (1.01 to 329.15 mg/kg); iron content (10.01 to 386.3 mg/kg); protein content (1.72 to 29.93%) and other physicochemical properties of grain. Many of these variations can be generated by conventional breeding methods to address the nutritional needs in developing countries. In addition, 3 accessions: TVu-13088, TVu-13495 and TVu-9725 that combined the largest number of desirable nutritional attributes were identified which can be nominated for anti-nutritional factor testing prior to recommendation for infant diets formulation and other use. For nutrient enhancement, five accessions each were identified for protein, zinc and iron contents. Genetic diversity of 169 cowpea accessions using 119 SNP markers clustered the accessions into two main groups on genetic distances (0.00 to 0.212) with small genetic differentiation (0.26 to 0.45) between African and USA cowpea accessions. This indicates that the entire genetic diversity in the African germplasm might already have spread over cowpea-growing regions in the world as a whole, though not completely within any single region. The Polymorphism Information Content (PIC) values ranged from 0.2366 (7344_500 SNP) to 0.427 in two SNP markers (4749_1972 and 14929_258). Weak negative correlation existed between iron content and fat (r= -0.18, P < 0.007), iron content and carbohydrate (r= -0.18, P < 0.007) but iron content was positively correlated with protein (r= 0.26, P < 0.001) content. Fat content was negatively correlated with ash content (r= -0.13, P < 0.05) and protein content (r= -0.85, P < 0.001). Ash content correlated positively with protein (r= 0.14, P < 0.05) and negatively with carbohydrate (r=-0.23, P < 0.001). Protein was negatively correlated with carbohydrate (r= -0.29, P < 0.01). Zinc concentration showed weak negative significant (r= 0.03, P < 0.05) correlation with number of pods per plant. No significant correlation was observed between zinc concentration and grain weight. Similarly negative…

▼ This study examined the development potential of Kenya‘s transnational migrants in
the United Kingdom (UK), the United States of America (US), Canada and
Ghana and
how it can be leveraged towards the realization of Kenya‘s long term development plan
- Kenya‘s Vision 2030. There is an upsurge of interest on the linkages between
migration and development due to the realization that apart from the negative impact
that migration can have on the countries of origin, migrants have much development
potential which is largely unexploited. To explore how the development potential of
Kenyan migrants can be mobilized towards the country‘s development, this study
examined migrants‘ transnational involvement in remittance transfers, return-visits,
savings, and investments. The study used mixed research methods in data collection
and analysis: a survey of 212 respondents, 21 in-depth interviews and 5 focus group
discussions.
Overall, the study revealed that most of the Kenyan migrants in the four countries are
actively involved in remittance transfers, return-visits, savings and investments in
Kenya and they therefore form a potent development resource for the country.
Nonetheless, this development potential has not been fully realized due to the numerous
challenges the migrants encounter in their transnational engagement. The other key
finding of the study is that most of the Kenyan migrants in the study are relatively
young (92% are below 47 years) and highly skilled professionals (76% have a
minimum of a bachelor‘s degree) who can be of immense benefit to Kenya from skills
and knowledge transfer. But as the findings indicated most Kenyan migrants are
scarcely informed about the objectives of Kenya‘s Vision 2030 and therefore may not
be consciously involved in its realization. Based on these findings the study
recommends an all-inclusive migrants‘ engagement strategy that will swiftly identify
and address the concerns of the Kenyan migrants so as to encourage them to get more
involved in national development. The study also recommends the improvement of
information dissemination to the Kenyan diaspora. The objectives of Kenya‘s Vision
2030 should be clearly explained to the Kenyan diaspora and they should also be
informed about available opportunities in Kenya. This study gives empirical support to
the growing recognition of migrants‘ potential to contribute to the development of their
home countries. It also contributes to the novel web survey data collection method. The
study collected data from a study population that was scattered in four geographically
dispersed countries using Surveymonkey web survey tool.

▼ Diarrhoea is a major public health problem that affects the physical and cognitive
development of young children. Anthropometric data was collected from 274
children, 170 with diarrhoea and 104 without diarrhoea. Stool specimens were
analyzed by conventional culture, PCR for EAEC, Shigella, Cryptosporidium,
Entamoeba, and Giardia species, as well as by ELISA for faecal lactoferrin
levels. Additionally, all E. coli recovered from culture were PCR screened for
EAEC, and compared with those obtained from the stool DNA. Multiple gene loci
(aaiC, aap, attA and aggR) were sought for EAEC. About 50% of the study
population was mildly to severely malnourished. Mild to severe malnutrition
(WAZ <-l), moderate to severe stunting (HAZ < -2) and moderate to severe
wasting (WHZ < -2) were associated with diarrhoea (p = 0.023, 0.026 and 0.062,
respectively). In only 1 of 170 diarrhoea stool specimen was Shigella flexneri
recovered by culture. EAEC and Cryptosporidium were associated with diarrhoea
(p = 0.048 and 0.011, respectively), and malnourished children who had diarrhoea
were often co-infected with both Cryptosporidium and EAEC. About 27 % (4/15)
C. parvum genotypes were identified by HRM analysis. Faecal lactoferrin levels
were higher in children with diarrhoea (p = 0.019). Children who had EAEC
infection, with or without diarrhoea had high mean lactoferrin levels irrespective
of nutritional status. In conclusion, the current study identified high levels of
growth deficits among the children with/without diarrhoea. The use of DNAbiomarkers
revealed that EAEC and Cryptosporidium were common intestinal
pathogens in Accra, and that elevated faecal lactoferrin was associated with diarrhoea in this group of children. EAEC’s dispersin gene (aap) was significantly
associated with diarrhoea in both the faecal and bacterial DNAs, in the children
studied (p < 0.05).

▼ Out-of-pocket payments for healthcare in low and middle income countries have potentially
catastrophic consequences for vulnerable households. These can lead to vicious cycles of
impoverishment and debt.
Ghana introduced the National Health Insurance Scheme (NHIS) to
protect Ghanaian residents from the financial consequences of health and illness shocks.
This thesis contributes to the discussion on the economic consequences of high Out-of-Pocket
(OOP) payments for health care. The sixth round of the
Ghana Living Standards Survey,
collected over the period between August 2012 and August 2013 from a nationally representative
sample of 16,772 households was used as the main data set. A probit model was used to predict
enrollment in NHIS. Also, catastrophic health expenditures (defined as out-of-pocket health
expenditures exceeding set thresholds and causing economic suffering to the household) were
further adjusted by concentration indices that indicate whether the distribution of these payments
are different between the rich and the poor. Health Expenditures are deemed Catastrophic when
they go beyond the set threshold at which the livelihood of a household is adversely affected
causing them to become poor or poorer. The catastrophic expenditures were then regressed on a
number of household socio-economic factors to determine factors that predict the incurrence of
such expenditures.
The analyses showed that only 1.1% of Ghanaian households incurred catastrophic health
expenditures. On average, these payments have low intensity of 0.001% (in excess of the
catastrophic threshold – 10% of household expenditure being the proportion beyond which a
household may become impoverished or deeper impoverished by out-of-pocket health
expenditures). The regression results showed that households that have insurance coverage are
found to be 2.4 percentage points less likely to incur catastrophic health expenditures than households without health insurance. However, the burden of such payments is found to be
heavier on poorer households.
Thus, NHIS was found to offer some financial protection against catastrophic health
expenditures among Ghanaian households. Education on the indispensability of the NHIS to
sustenance of livelihood should be intensified among the poor and the very poor in
Ghana,

▼ The main goal of this study is to describe the morphological properties of C’lela; a
Niger-Congo, Western Kainji language spoken in the eastern part of Kebbi State,
Nigeria. The study mainly adopted the classic descriptive model of linguistics in
particular to explore and highlight the morphological processes and properties of
C’lela. The relevant data for the study were sourced mainly from the extant literature on
C’lela as well as the field data. By and large, the primary data were corroborated with
the secondary sources.
The study established that C’lela has distinctive morphological properties akin to other
languages across West Africa. C’lela uses prefixes and suffixes on nominal and verbal
categories to provide information about number and tense, and equally undergoes the
major morphological processes such as compounding, derivation, affixation, and
reduplication. In terms of derivation it was revealed that though derivational processes
in C’lela are analyzable mainly on the principles of concatenative morphology where
prefixes and suffixes are in concatenative relationship with their host stems, the
language also lends itself to non-concatenative morphology, where the internal stem-
vowel, instead of affixes, contains the syntactic and semantic information in the
derivation. This suggests that C’lela has a derivational system that exploits affixation,
as well as internal modification. With regard to compounding, it emerged that C’lela is
an endocentric but a left-headed language. It was also realized that the language
exhibits both partial and complete reduplications, which in most cases are lexical and
semantic in function. It was particularly noted that the complete reduplication of verbs
that contain heavy-initial disyllabic stems in C’lela are accompanied by phonological
operations such as syllable truncation and imbrication.
The study while illustrating the chief morphological processes inherent in C’lela,
endeavored to examine and highlight the various phonological processes that are often
triggered when stems come into contact with affixes or when compounding and/or
reduplication take place. These morphophonological processes include but are not

▼ In spite of the available modern technologies for dealing with ill-health, many people
continue to resort to divination in the search for therapy. The persistence of the practice of
divination in health seeking suggests that there is a considerable use derived from its practice.
Against this background this study was conducted to assess the extent to which divination
influences health-seeking behaviour as people utilise modern healthcare facilities in the
Talensi-Nabdam district in Northern
Ghana, findings of which could provide clues to some
barriers to healthcare delivery and utilization in
Ghana at large.
A mixed-method approach involving Focus Group Discussions with community elders, in-
depth interviews with practicing diviners and experienced healthcare practitioners, and a
community survey using a questionnaire was used. Analysis involved triangulation of both
the qualitative and quantitative data. Qualitative data was analysed by importing verbatim
transcripts of all interviews and discussions into Nvivo-7 software, while quantitative
analyses involved logistic regression procedures, using Stata-10 software.
The use of divination in health seeking was found to be significantly correlated with age, sex,
marital status, number of wives possessed by men, number of children, level of education and
religious affiliation. Findings also suggest that on the pathway between symptoms
recognition and therapy options divination is often employed to pin down supernatural and
other causes of misfortunes and ill-health and to determine the appropriate patterns of resort.
Patients with such diseases as burns, boils, anthrax, and snakebites tend to consult diviners
first as they believe these conditions are of spiritual or supernatural origin. Diviners don’t
consider themselves as healers, but rather consider themselves merely as custodians of the
spiritual conduits by which people can find out the causes of ill-health and other misfortunes
from the spiritual and ancestral world in order to determine the course of action.
The findings have implications for healthcare service and utilization: delays in seeking and
utilising modern healthcare services and the tendency for patients asking for “discharge
against medical advice” to enable alternative treatment at home, as well as reasons for
treatment failures at modern healthcare facilities.
It is proposed that a bio-psycho-social-spiritual model should be integrated into clinical care
of patients at modern healthcare facilities especially in diagnostic interviews and treatment
regimes of patients. Collaboration between the
Ghana Health Service and diviners together
with other magico-religious healthcare practitioners could facilitate incorporation of this
model into medical and nursing training curricular.

▼ Lake Bosumtwi is an important natural inland freshwater meteorite crater lake due to its scientific and socio-economic importance to both local and international communities. Although groundwater has been the main source of water supply for people living around the lake and visitors/tourists, very little work has been conducted with regard to the quality of the groundwater delivered by the aquifers within the lake basin. These aquifers are made up of the metasediments of the Birimian Supergroup and boreholes that are mostly fitted with pumps tap the groundwater.
A combination of conventional graphical methods, multivariate statistical and mass balance models have been applied to surface water in Lake Bosumtwi and groundwater hydrochemical and stable isotope (δ2H and δ18O) data from Birimian aquifers around the lake. The objective was to contribute to and improve the understanding of the hydrochemistry of the lake water and groundwater in aquifers around the lake and also to understand the relationship between these two reservoirs.
Results indicate that groundwater is of good to excellent quality for domestic use and is generally suitable for irrigation in comparison to the lake water that has high salinity and high sodicity and is, therefore, not suitable for irrigation. Hydrochemical and isotopic (i.e., δ2H and δ18O) compositions of the groundwater and lake water suggest that there is no apparent incipient hydraulic relationship, which benefits the main aquifer system in terms of recharge from the lake. However, the reverse process, whereby the lake receives contribution from the aquifers through subsurface flow cannot be discounted on the basis of the data from this research.
iii
Recharge of the aquifers appears to occur on hilltops where the water is characteristically acidic with low level of mineralization, suggesting short residence time. The groundwater within the basin has been recharged by recent meteoric water that has undergone evaporative enrichment prior to recharge. Evaporative loss in the range of 45% to 51% has been estimated for rainwater available for infiltration and subsequent recharge. The lake water is considerably enriched relative to the heavier isotopes of hydrogen and oxygen as a result of severe evaporation over the open lake surface. Estimated evaporative loss over the lake surface is about 82% resulting in the concentration of the univalent cations in the Lake.
Q-mode hierarchical cluster analysis (HCA) of the hydrochemical data employed to examine the spatial distribution of the investigated samples resulted in four spatial clusters (C1 to C4). Conventional graphical plots of the hydrochemical compositions of these clusters combined with mass balance hydrochemical modelling suggested that the groundwater has evolved from Na-Mg rich water types located on hill tops to Ca-Mg rich hydrochemical facies at the lower reaches of the crater. The relevant reactive minerals within the aquifers and the geochemical processes that control the hydrochemical evolution of the groundwater and lake…

▼ This study examined the extent to which Africentric worldview influence the relationship between
stress and psychological health among primary caregivers of children with intellectual disability
in Ghana using the mixed methods design. The quantitative phase recruited and assessed 160
primary caregivers using standardized measures assessing Stress, Africentric worldview,
Africultural coping, and Psychological health. Results from MANOVA indicated that primary
caregivers of children with intellectual disability experience significantly high levels of stress and
poor psychological health than primary caregivers of children with sickle cell disease and healthy
controls. Results from hierarchical regression analyses on primary caregivers of children with
intellectual disability indicated that; first, caring for an intellectually disabled child is associated
with high levels of stress which further leads to poor psychological health. Second, spirituality
buffered the relationship between stress and anxiety. Third, Africentric values of spirituality and
intuition predicted spiritual coping.
The qualitative phase adopted semi-structured interviews with 11 primary caregivers of
children with intellectual disability to inquire about their stressors and coping strategies. Using
thematic analysis, emergent themes included; psychological reactions, caregiving challenges,
societal reactions, coping strategies, psychological functioning, knowledge of condition, and
perceived cause of disability. Despite the numerous challenges associated with caregiving,
primary caregivers of children with intellectual disability reported the significance of their
spirituality, family/community support systems, and hope as effective coping strategies in raising
their children. Results from both the quantitative and qualitative phases demonstrated the stressful nature of raising a child with intellectual disability and the importance of Africentric values of
spirituality and communal support systems in coping. Implications for clinical intervention programmes, research, policy, and psychological education are discussed.
