Access To Clean Energy In Africa Revisited: The Roles Of Women Empowerment, Corruption Control, FDI And Sectoral Growth.
(Plos One, 2025-02-04) Adjei-Mantey, K.; Kwakwa, P.A.; Ankrah, E.
One of the key contributors to climate change is energy consumption, with the type of
energy used having implications on the natural environment and health of users. To pro mote environmental sustainability and sustainable development, Sustainable Development
Goal (SDG) 7 aims to achieve accessibility, and affordability of clean and modern forms of
energy for all. This study aims to investigate the effects of women empowerment, cor ruption control, foreign direct investment, and sectoral growth on access to clean energy
in Africa, as well as the effects of the interrelatedness of these factors on clean energy
access. Using data on 32 countries in Africa from 2002 to 2021 and rigorous econometric
techniques, the study finds that women empowerment and corruption control significantly
increase access to clean energy in Africa while sectoral analyses show varying effects of
growth in the different sectors on clean energy accessibility. Furthermore, it is found that
corruption control is not able to reverse situations of adverse effects of some variables on
access to clean energy in some cases, likely due to the low levels of corruption control in
Africa. The results suggest that African countries could enhance access to clean energy
for its citizens and harness the full potential of clean energy, to promote sustainable devel opment and improve the lives of their population, by empowering women, fighting corrup tion, and cultivating balanced economic growth.
Expression Pattern of APC And P53 Proteins in Left-Sided and Right-Sided Colorectal Cancer in Ghanaians
(University of Ghana, 2023) Asaku, B N A.
Background: The development of colorectal cancer tumours is significantly impacted by the loss
of APC and p53 protein function. The anatomical difference between the left and right colon,
significantly influence tumorigenesis of left-sided and right-sided colorectal cancers. Additionally,
because of genetic and environmental differences, there are variations in how APC and p53 affect
the tumorigenesis of left- and right-sided colorectal cancer in different racial groups. Differences
in the genetic characterization of left-sided and right-sided colorectal cancers has informed the use
of tailor-made treatment that has contributed to increased survival rate in the developed countries.
Aim: This study aimed to determine the expression pattern of APC and p53 proteins in left and
right-sided colorectal cancer in Ghanaians and compare results to expression pattern of APC and
p53 in left and right normal colon.
Methodology: Ninety formalin-fixed paraffin-embedded blocks were subjected to semi automated immunohistochemistry staining to determine the pattern of APC and p53 protein
expression in left-sided and right-sided colorectal cancers. Two independent assessors scored the
expression levels of the APC and p53 proteins in colorectal cancer and healthy colon tissues
independently, and Cohen's Kappa was used to determine the inter-rater reliability of the results.
To determine the significance of these proteins in the development and progression of colorectal
cancer in Ghanaians, the expression of the APC and p53 proteins in left-sided and right-sided
colorectal cancer were compared to the controls.
Result: APC protein was found in 74.4% of the total number of colorectal cancer cases and 100%
of normal colons, with a p-value of 0.012. Protein p53 was found in 73.3% of colorectal cancers
compared to 94.7% of normal colon (p-value = 0.044). APC protein expression was found in 70% of left-sided colorectal cancer and 100% of left normal colon. APC protein expression was found
in 86.7% of right-sided colorectal cancers and 100% of right normal colon. The p53 protein was
expressed in 75% of left-sided colorectal cancers and 100% of left normal colons. Protein p53
expression was found in 70% of right-sided colorectal cancers and 87.5% of right normal colons.
With a p-value of 0.001, high p53 expression was significantly associated with LCRCs versus
RCRCs. There was no correlation between protein expression and tumour stage or grade.
Conclusion: The significant difference in APC expression between healthy and cancerous colons
demonstrates that loss of APC expression influences the development of colorectal cancer in a
small percentage of Ghanaians. The high proportion of APC protein expression in both left-sided
and right-sided colorectal cancers may demonstrate the majority of colorectal cancers in Ghanaians
are not caused by loss of expression of wild type APC protein, and that other molecular genetic
factors contribute to the initiation of colorectal cancer in Ghanaians.
The Socio-Cultural Impacts of Flimani Kɔku Dance and Rituals on Kadzakɔƒe - An Ethnographic Overview.
(University of Ghana, 2022) Torgboh, J.
This study documents the historical origins and significance of Flimani Kɔku, its dance, song and
ritual performances in Kadzakɔƒe, a small farming community in the Ketu South District of the
Volta Region of Ghana. Just like Yeve, Flimani Kɔku and its variants Afesa and Tu are restricted
societies whose rituals and practices are strictly kept from the public space although many people
are aware of the fascinating supernatural powers that are put in the public domain on celebratory
occasions among the Ewes. The practice of Flimani Kɔku and its variants Afesa and Tu are mainly
the preserve of the Ewe ethnic group that is spread across West Africa including Ghana, Togo,
Benin and some parts of Nigeria. Essentially, Flimani Kɔku, which is the focus of this study, is
an Aŋlɔ-Eʋe religious and cultural practice with its own music and dance patterns.
The study, therefore, presents the significance of Flimani Kɔku, by documenting its practice –
dance and music performance patterns as well as its values and rituals in Kadzakɔƒe. This study
area of study is complete virgin territory and was therefore replete with some challenges, which
but for the researcher‟s own early immersion into vodu practice, would have derailed the work.
In documenting Flimani Kɔku, the study conceptualises the practice as an embodiment of
AŋlɔEʋe indigenous Knowledge systems and is an archive of history, beliefs and culture, which
impart social values and a sense of identity by ensuring the spiritual development of its members.
The study therefore aims to preserve and protect the practice from the onslaught of foreign
religions, especially the Judeo-Christian faith, which is at the forefront of denigrating traditional
religious practices as exemplified in a similar attack on the „Trokosi‟ religious practice with the
justification that it was not a „religion‟ but an enslavement of women and girls.
Based on the data collected by this study, Flimani Kɔku practice is clearly not only an age-long
religious belief of Kadzakɔƒe of other Aŋlɔ-Eʋe communities who benefit from its spiritual protection and guidance, the inculcation of moral values, impartation of generational knowledge
while fostering social cohesion in the communities of practice.
The study relies on an ethnographic field work approach which explores and documents the
practice of Flimani Koku through participant observation and other ethnographic techniques in
the community of Kadzakope.
Finally, the study used a qualitative approach of enquiry of intensive ethnographic exploration
with its tools and mechanisms - interviews, focus group discussions, observation, participant
observation and audio-visual recordings - in documenting Flimani Kɔku, its history, dance and
socio-cultural impact on the Kadzakɔƒe
Mental Health Status of Health Care Workers in Saltpond Government Hospital in the Context of Covid-19
(University of Ghana, 2023) Ameyaw, I.
Title of study: Mental health status of health care workers in Saltpond government hospital in the
context of COVID-19.
Background: The COVID-19 pandemic has had a significant impact on public mental health.
During a pandemic, healthcare workers (HCWs) are exposed to many stresses that predispose them
to psychological disorders. To learn more about these issues, this study was conducted to assess
the mental health status of health care workers in a selected government hospital in Ghana. The
outcome of this study is expected to inform strategies to improve mental health status of health
workers in such situations.
Method: This study used a cross-sectional analytic design with a simple random sampling method
and a close-ended structured questionnaire to collect data. Chi square and fisher exact tests and
multiple logistic regression were used to identify and test the association between dependent and
independent variables. A total of 296 healthcare workers in Saltpond Government Hospital were
involved in the study.
Results: Among healthcare professionals, depression, anxiety, and stress was prevalent.
Approximately 55(20.27%) health workers were depressed, 44(15.07%) anxious, and 76(22.79%)
stressed. The study found that depression, anxiety, and stress were significantly associated with
socio-demographic characteristics such as marital status and gender. About 169(57.24%) had
“excellent knowledge” and 102(34.48%) had “good knowledge” of COVID-19 among the
participants.
Conclusion and Recommendations: A significant proportion of health workers in the study area
were found to be depressed, anxious, and stressed. Mental health services should be strengthened by the Ghana Health Service (GHS) to reduce the prevalence of depression, anxiety, and stress
among healthcare workers. Periodic screening should be conducted among hospital staff. The
counseling and public health education units of GHS should be strengthened to enhance awareness
among healthcare workers the signs and symptoms of depression, anxiety, and stress and relevant
coping strategies.
Effect of Pretreatment Times on the Quality Characteristics of Orange Fleshed Sweet Potato (Ofsp) Flour
(University of Ghana, 2023) Akpey, M.
Orange Fleshed Sweet Potato (OFSP) flour presents a promising alternative to traditional flours,
offering enhanced nutritional benefits, particularly in Vitamin A content. This research delves into
the drying characteristics of OFSP slices and the subsequent quality of its flour. The primary focus
was to ascertain the impact of chemical and hot water blanching pretreatment durations prior to
air drying at varied temperatures.
The OFSP samples, sourced from a farm, underwent a process of washing, peeling, and slicing to
a thickness of 3mm. These samples were then subjected to blanching in hot water and ascorbic
acid for durations ranging from 1 to 3 minutes, followed by drying at temperatures of 50, 60, and
70℃. Key drying characteristics, such as drying curves, moisture ratio, and effective moisture
diffusivity, were meticulously studied. Quality attributes, including color, water absorption
capacity, and swelling index, were also analyzed, with color assessment conducted using a
HunterLab colorimeter.
Findings revealed that a drying temperature of 70℃ resulted in the shortest drying time. Ascorbic
acid pretreatment for 3 minutes retained the highest moisture content across all temperatures.
Effective moisture diffusivity values oscillated between 1.081 to 1.171×10-9 m²/s, with samples
dried at 70℃ showcasing higher values. Five thin-layer models were employed to interpret the
drying curves, with the Page model proving optimal for temperatures of 50oC and 60℃, and the
logarithmic model for 70℃.
The research underscores that varying combinations of pretreatment, duration, and drying
temperature can yield diverse outcomes concerning quality criteria. In the broader context of the
food industry, the insights from this study can pave the way for the large-scale production of high-quality OFSP flour, potentially revolutionizing flour-based products with enhanced nutritional
profiles.
