- ItemGender and leadership positions: understanding women’s experiences and challenges in patriarchal societies in Northern Ghana(International Journal of Sociology and Social Policy, 2023) Adongo, Awinaba Amoah; Dapaah, Jonathan Mensah; Azumah, Francess Dufie; 0000-0002-0261-3295; 0000-0002-9349-6273; 0000-0001-6023-8000Purpose – Women are rarely seen in positions of leadership in patriarchal societies, which is unsurprising.Following gender equity policies, few women have been able to break through the gender equity barrier and assume leadership positions in schools. Few research investigations have delved into the experiences and challenges that women encounter in positions of leadership in patriarchal societies in government schools in Northern Ghana. The study seeks to comprehend the experiences and challenges that women confront in positions of leadership in patriarchal societies in Northern Ghana. Design/methodology/approach – The study aimed to gain a better understanding of the experiences and challenges that women encounter in educational leadership roles in patriarchal societies in Northern Ghana. To achieve the study’s objectives, a quantitative research approach and a social survey design were used, as well as descriptive and inferential statistics. Findings – The findings of the study revealed that in patriarchal societies in Northern Ghana, women experience conventional gender roles that conflict with roles, cultural values, gender stereotyping, family responsibilities and cultural beliefs and perceptions of women and attitudes and low expectations of women’s managerial skills discourage women from taking on leadership positions in men-dominated societies.
- ItemBuilding the capacity of students in creative problem-solving and critical thinking skills: Aesthetic narrative of Ayigya Township, Ghana(Royallite Global, 2023) Kquofi, Steve; Adom, Dickson; https://orcid.org/0000-0001-6263-615X; https://orcid.org/0000-0002-0559-4173The study set out to investigate the environmental aesthetics present in habitual areas, specifically in Ayigya Township, Ashanti Region, focusing on picture-making tendencies for optimal skill development. A total of 346 respondents from various structures were specifically chosen to participate in the study using the Narrative Case Study Design under the qualitative research approach. Semi-structured interviews, observation, and photographic documentation were used for the data collection. The data were analysed using photographic documentary and qualitative narrative analysis. The findings demonstrated how dispersed aesthetic elements are in everyday life and how this appreciation would have a positive impact on the Senior High School student’s capacity for creative problem-solving and critical thinking skills. It is suggested that students develop alternative means of expressing their creativity. The study contends that art teachers must help students to use aesthetics in their environments to develop the tools and materials for their artistic productions.
- ItemOn the dynamics of the Tent function-Phase diagrams(Modem Science Publishers, 2016-05) Kwabi P. A.; Obeng Denteh, William; Boadi, Richard Kena; Ayekple, Yao ElikemThis paper focuses on the study of a one dimensional topological dynamical system, the tent function. We give a good background to the theory of dynamical systems while establishing the important asymptotic properties of topological dynamical systems that distinguishes it from other fields by way of an example - the tent function. A precise definition of the tent function is given and iterates are clearly shown using the phase diagrams. By this same method, chaos in the tent map is shown as iterates become higher. We also show that the tent map has infinitely many chaotic orbits and also express some important features of chaos such as topological transitivity, boundedness and sensitivity to change in initial conditions from a topological viewpoint.
- ItemA MATHEMATICAL MODEL OF COVID-19 TRANSMISSION DYNAMICS WITH EFFECTS OF AWARENESS AND VACCINATION PROGRAM(Journal of Ghana Science Association, 2023-10) Agbata, B.C.; Shior, M.M.; Obeng-Denteh, W.; Omotehinwa, T.O.; Paul, R.V.; Kwabi P. A.; Asante-Mensa, FThis study introduces a deterministic mathematical model for understanding the transmission dynamics of COVID-19, con sidering the influence of vaccination and awareness program, which target susceptible individuals. The model is based on a system of differential equations, resulting in an SVEIR model. Through qualitative analysis, various aspects of the model, such as disease-free equilibrium, endemic equilibrium, basic reproduction number, and local and global stability, were thoroughly explored. The disease-free equilibrium is proven to be both locally and globally stable when R0 < 1, while it ∼becomes unstable when R0 > 1. Simulation results demonstrate that the combination of vaccination and awareness programs emerges as the most effective approach to mitigate the spread of COVID-19 within the population.
- ItemMolecular characterization of interactions between the D614G variant of SARS-CoV-2 S-protein and neutralizing antibodies: A computational approach(Infection, Genetics and Evolution, 2021) Kwarteng, Alexander; Asiedu, Ebenezer; Sylverken, Augustina Angelina; Larbi, Amma; Sakyi, Samuel Asamoah; Asiedu, Samuel Opoku; 0000-0002-0893-2908; 0000-0003-2867-1984; 0000-0002-7691-914X; 0000-0002-3814-6924; 0000-0001-5168-4762; 0000-0002-0352-3195The D614G variant of SARS-CoV-2 S-protein emerged in early 2020 and quickly became the dominant circulating strain in Europe and its environs. The variant was characterized by the higher viral load, which is not associated with disease severity, higher incorporation into the virion, and high cell entry via ACE-2 and TMPRSS2. Previous strains of the coronavirus and the current SARS-CoV-2 have demonstrated the selection of mutations as a mechanism of escaping immune responses. In this study, we used molecular dynamics simulation and MM-PBSA binding energy analysis to provide insights into the behaviour of the D614G S-protein at the molecular level and describe the neutralization mechanism of this variant. Our results show that the D614G S-protein adopts distinct conformational dynamics which is skewed towards the open-state conformation more than the closed-state conformation of the wild-type S-protein. Residue-specific variation of amino acid flexibility and domain specific RMSD suggest that the mutation causes an allosteric conformational change in the RBD. Evaluation of the interaction energies between the S-protein and neutralizing antibodies show that the mutation may enhance, reduce or not affect the neutralizing interactions depending on the neutralizing antibody, especially if it targets the RBD. The results of this study have shed insights into the behaviour of the D614G S-protein at the molecular level and provided a glimpse of the neutralization mechanism of this variant.
