Chaotic Phenomena and Oscillations in Dynamical Behaviour of Financial System via Fractional Calculus

In this research work, we formulate the phenomena of the financial system in the fractional framework to describe the complex nature of finance. The basic definitions and ideas of the Caputo-Fabrizio fractional operator are listed. We introduce a novel numerical technique for the dynamical behaviour of our fractional model. The oscillatory and chaotic behaviour of the model is studied with the variation of various input parameters on the model. We have shown that there exists strong oscillatory and chaotic behaviour in the system; moreover, we highlighted the impact of fractional-order parameter on the model. The conditions for the local complex behaviour of the system are analyzed with the impact of certain parameters on the macroeconomic. Our findings suggest that the values of initial conditions, fractional order, and input parameters can lessen the chaos of the proposed financial system. � 2022 Zahir Shah et al.

Character development in Ghanaian tertiary education examining students levels of spirituality and moral development

Research has shown much concern about blending academic training with character development, as antidote to students’ vices in higher institutions. Developmental theories revealed that spirituality and moral development are relevant concepts in framing character development in higher education. However, little has been done in Ghana to probe into student’s levels of spirituality and moral development as constructs of character development. The purpose of the study was to explore the levels of university students’ spirituality and moral development as they influence character development and to create the awareness for educators to attend to the affective developmental needs and growth of students. The design was sequential explanatory mixed method using a questionnaire and an interview guide. Two published instruments, DIT-2 and SIBS-R, combined as one questionnaire with two parts to survey students (n=441) for quantitative data on spirituality and moral development respectively. Findings were presented in descriptive statistics, various statistical tests (t-tests and ANOVA) for differences among groups, and a correlation coefficient to establish relationship between the variables, spirituality and moral development. Focus group interviews (n=50) were conducted, transcribed and coded, and later integrated with the quantitative data to draw conclusions. Most of the students’ levels of spirituality were moderate or high (M=78.78, SD=9.52). Levels of moral development were higher at the maintaining norms stage (M=35.38, SD=13.52), with N2 score within the range of 20s. Both phases of the study showed students’ interest to enhance their spirituality and moral development. Hence, the desire of the majority of students for inclusion of character education in their training. Recommendations were for policy, practice and future research for higher institutional leadership to address students’ spirituality and morality needs and growth.

Characterisation and quality assessment of surface and groundwater in and around Lake Bosumtwi impact craton (Ghana)

Conventional graphical methods have been used to classify water in Lake Bosumtwi and groundwater around the lake. The study also assessed the suitability of these water resources for agricultural use. Results indicate slightly acidic, moderately hard to very hard groundwater with alkaline earth concentrations exceeding alkali metals. In contrast, the lake water is alkaline, showing alkalis in excess over alkaline earth metals. Weak acids exceed strong acids in both lake/groundwater. Rock weathering largely controls groundwater and lake water chemical compositions, resulting mainly in Ca�Mg�HCO3 groundwater and Na�HCO3 lake water types. Thus, suggesting that there is no apparent incipient relationship, which benefits the primary aquifer system in terms of recharge. Water quality indices suggest groundwater of good to excellent quality for human consumption and other domestic use. An evaluation of lake/groundwater based on salinity, sodicity and bicarbonate hazard reveals that the groundwater is generally suitable for irrigation whiles the lake water is not suitable for irrigation. However, the lake water may be used in generous amounts on highly permeable soils and salt-tolerant crops under special soil and water management practices. � 2021, The Author(s), under exclusive licence to Springer Nature Switzerland AG.

Characterisation in Dagbamba folktales

This thesis examines characterisation in Dagbamba folktales. Dagbani is a Mabia language spoken in the Northern Region of Ghana by the Dagbamba. The study aims at exploring the characters in Dagbamba folktales that reflect the philosophies of the Dagbamba in the viewpoint of mimesis as a theoretical framework. It also looks into the individual themes found in these tales. The study reveals that, just as in many other cultures, the Dagbamba employ animals, human beings, objects and supernatural beings as characters in their tales. These characters exhibit unique traits such as hardwork, compassion and generosity. These characters depict the Dagbamba viewpoint of the world. The study uncovered specific themes such as respect for others and unity is strength in the individual Dagbamba tales. Data for the study were qualitatively collected from both primary and secondary sources. The primary data were collected through semi-structured interviews and native speakers‟ intuition, whiles the secondary data were collected from a Dagbani story book with the title, Dagbani Salin’nyaɣisa, which means, “Interesting Dagbani stories” It is expected that findings of this thesis would contribute to the prevailing literature on characterisation cross-linguistically.

Characteristics of ethical decision-making process of school leaders in public senior high schools in Dormaa Ahenkro municipality of Brong- Ahafo region in Ghana

The purpose of this study was to examine the characteristics of ethical decision-making of Senior High School leaders in the Dormaa Ahenkro Municipality of the Brong-Ahafo Region of Ghana. The study was a descriptive survey that employed a mixed method approach. The study used census method to select 66 respondents consisting of Headmasters/mistresses, Assistant Heads, Senior House masters and Mistresses and Housemasters and mistresses. Descriptive statistics were used to analyse the data. The study found that school leaders were essentially pre-disposed to be professional in ethical decision-making with a tendency to applying school rules and regulations. Respondents overwhelmingly adopted the professional ethical framework to resolve ethical dilemma but also utilized ethics of care, justice and critique in their decision. The notable background characteristic of respondent‟s position and experience at that position influenced their choice of framework but experience in teaching mediated their choice towards a more caring and just attitude. In conclusion, school leaders in Dormaa Ahenkro Municipality are inclined to be professional in their ethical decision making but also indicate a tendency towards adopting multiple ethical decision making frameworks. The study recommends that the professional code of practice and ethics be regularly interrogated to incorporate issues of care and justice. Also the study recommends among others that the Ghana Education Service takes measures to address the tendency towards use of other ethics rather than the professional as well as to organize community-school relationships.

Characteristics of small-scale pig farmers in the Binduri district of Upper East Region of Ghana

The study seeks to examine the characteristics of small-scale pig farmers in Binduri district. Simple random sampling was used to select twenty (20) communities in the district. However, snow ball’s sampling method was used to select ten (10) respondents from each community. In the district, 87.1% of small-scale pig farmers have the opinion that, their level of training on pig production practices has great negative effect on small scale pig farming. Hence, there is need for sufficient training on pig production practices especially for small-scale pig farmers in the district. This calls for government, Non-governmental Organizations (NGOs) and other stakeholders to step in to support small scale pig production in the Binduri district.

Characterization of density and selected anatomical features of stemwood and branchwood of E. cylindricum, E. angolense and K. ivorensis from natural forests in Ghana

This study investigated density and some anatomical features, and also assessed the correlations among them in stem and branch woods of Entandrophragma cylindricum, Entandrophragma angolense and Khaya ivorensis. Branch and stem wood samples were sampled from two natural forest reserves. Wood density was determined in accordance with ISO 3131 whereas anatomical investigations followed IAWA committee�s recommendations-1989. Results indicated that at 5% level of significance, wood density was significantly higher in branchwood than stemwood for all three species. Generally for all the three species, significant differences were found in fibre length and vessel diameter between branchwood and stemwood of same species but no significant differences were found in both ray and axial parenchyma quantities. Stemwood density correlated significantly and positively with fibre (r = 0.408, p < 0.01) and ray parenchyma (r = 0.280, p < 0.05) proportions but negatively with fibre length (r�=�?0.528, p < 0.01), vessel lumen diameter (r�=�?0.304, p < 0.05) and axial parenchyma proportion (r�=�?0.679, p < 0.01). However, branchwood density correlated significantly and positively with fibre (r = 0.505; p < 0.01) and axial parenchyma (r = 0.385; p < 0.01) proportions but negatively with fibre length (r�=�?0.316, p < 0.05), vessel proportion (r�=�?0.486, p < 0.01) and ray parenchyma proportion (r�=�?0.357, p < 0.01). The study suggests that wood type (stem or branch) is an important factor to consider in terms of their effect on some properties of products produced from them, since differences in fibre length, vessel lumen diameter and vessel proportion could affect strength, porosity, leachability, natural durability and drying properties of wood. � 2017, Springer-Verlag Berlin Heidelberg.

Characterization of fuel and mechanical properties of charred agricultural wastes: Experimental and statistical studies

The importance of parameters such as material type, compacting pressure, particle size, and their interactions in the manufacturing of charred briquette fuel for industrial and domestic use cannot be overemphasized because they have a considerable impact on briquette performance. In investigating the aforementioned phenomena, the Box�Behnken? Response Surface Design and ANOVA were used to analyze how briquette material type, particle size, compacting pressure and their interactions significantly influence the mechanical and combustion properties of charred briquettes made from palm kernel shells, corn cobs, sawdust, and rice husk. All three factors namely material type, compacting pressure and particle size, with all possible interactions are significant determinants of the relax densities and impact resistance of all the briquette samples. Meanwhile, water resistance of the sampled briquettes was significantly different for material type, pressure level as well as particle size, however, all factor interactions were insignificantly affected with palm kernel shell and rice husk recording the highest and lowest water resistance property. With regards to the combustion properties, apart from material type which significantly affected heating rate and specific fuel consumption, pressure and particle size together with all interactions did not have any significant influence on heating rate and specific fuel consumption. Finally, the findings provide a new perspective to investigate other agricultural residues which will diversify the energy resources of the country. � 2022 The Author(s)

Charismatic leadership has been a subject of considerable scholarly interest, and Former President Jerry John Rawlings as a prominent political figure, provides an intriguing case for exploration. The research aims to contribute to the broader understanding of how charismatic rhetoric is used in framing and trust building and its impact on public discourse. The analysis focuses on identifying recurring themes, sociopolitical issues, and elements of credibility patterns in Rawlings' speeches. The study employs qualitative research methods to sift through the content, identifying themes and rhetorical strategies that exemplify charismatic leadership. The research design, which is qualitative content analysis was used and through purposive sampling, six State of the Nation address speeches that showcase charismatic rhetoric elements were selected. The data collection technique involves document analysis, specifically using the written versions of Rawlings' speeches available from the website of the Ministry of Information. Ideological goals and visions, appeals to history, emphasize followers worth, emphasize collective identity, mention self confidence, mention past success, and similarities with followers were the charismatic themes discovered. Also, the findings revealed that Rawlings addressed five sociopolitical issues in his speeches, including accountability and anti-corruption, social justice and equity, democracy and freedom, Pan-Africanism, and youth empowerment. The study further uncovers three pivotal elements crucial for a communicator's credibility: honesty, competency, and the ability to inspire or instill hope for the future. The speeches reveal a compelling narrative of resilience, nationalism, and a call for societal transformation. His speeches not only served as a political tool but also as a means to inspire and mobilize the masses towards a common goal.

Chemistry Teachers’ perception of the use of simulation games in Chemical Equations Balancing

This study investigated the senior high school (SHS) chemistry teachers’ perception of the use of simulation games (SGs) in chemical equations balancing (CEB). The study employed a type 1 developmental research design in which SGs were designed, pilot-tested and finally developed. The developed SGs were implemented and evaluated in a two (2) day workshop using 35 chemistry teachers (made up of 20 males and 15 females) drawn from ten (10) SHS in the Sekondi-Takoradi Metropolis in the Western Region of Ghana. Questionnaire and interview were the two (2) instruments used for the study. The findings showed that majority (33 out of 35) chemistry teachers representing 94.2% agreed that SHS students had learning difficulties with regards to simple CEB. Again, all the 35 SHS chemistry teachers representing 100% indicated that they enjoyed the use of SGs materials and instructional approach in teaching simple CEB and that they wanted more of the SGs materials to be developed and used in teaching abstract chemistry concepts. It was recommended that stimulating experiments such as SGs approach should be designed and developed to interest students in the exciting field of chemistry so that more students may be drawn into studying chemistry.

Chemistry topic-difficulties perceived by SHS students and how they are addressed by their teachers and the prescribed textbooks

This study investigated chemistry topic difficulty perceived by SHS students and how the available textual materials and teachers help in addressing the difficulties. Five research questions guided the study. The study employed the descriptive survey design. The population comprised all SHS 3 chemistry students in eight schools selected from five administrative districts in Western Region. The sample size was 280 SHS 3 chemistry students and sixteen teachers. It was established that students perceived nine (9) out of the twenty carefully selected topics in the SHS curriculum to be difficult. According to the students, the most difficult topic in the SHS chemistry curriculum was ‘Redox Reactions’ followed by ‘Electrochemistry’ and ‘Nomenclature of Organic Compounds’. The respondents noted the abstract nature of the topics, lack of practical activities, unavailability of prescribed textbooks, and uninteresting lessons as some of the causes of topic difficulty. The study established no significant difference in the topics perceived to be difficult by both male and female students. Again, it was revealed that the chemistry teachers’ instructional strategies contributed to students’ perceived topic difficulty in the selected schools. Surprisingly, some of the available textual materials in use by both teachers and students did not meet the requirements of good textbooks. Specifically, the language level of some of the books was above the students, while some of the books did not provide topic summary and learning objectives. Additionally, there were inadequate exercises for students. It was recommended that as much as possible, simple language should be used in writing chemistry books and, more specifically, in explaining difficult concepts. It was recommended that books should be revised often and that worked examples and exercises should be provided after authors had treated the topics.

Chief executive officers’ social media use a study of selected personalities in Ghana

The study examines the kinds of posts CEOs share on social media and further investigates how the concepts of self-branding and corporate branding are enacted through the posts. This research, through the lens of Goffman’s Presentation of Self and the theory of identity construction, and anchored on a case study design interrogates Facebook and Twitter posts of two purposively selected CEOs. This study indicates that the selected CEOs share posts on governance, their personalities, global issues, social and organisational subjects. Also, the study reveals that the CEOs present themselves positively to appeal to their social media followers. This assertion is supported by the CEOs branding of themselves as organisational leaders, corporate spokespersons, social commentators, influencers, globetrotters, religious people and gender advocates. Further, the study showed that the images of the organisations the selected CEOs head are shaped positively through their social media use. In effect, CEOs portray their organisations as competent, innovative and impactful. The study concludes that the CEOs construct, modify, maintain and promote their identities and that of their organisations on social media.

Chieftaincy in Builsa, 1900-1957

The study explores the role of British colonial rule in shaping chieftaincy institutions in Builsa. The Builsa people occupy the western end of the Upper East Region of Ghana. They were annexed into the British colonial system in 1902 by Major Morris’ led expedition to the Northern Territories. The socio-political aspects of their society particularly chieftaincy institutions experienced significant changes under British rule on the Gold Coast. Before the advancement of the British to the area, all the Builsa villages and towns were politically independent and autonomous from one another headed by clan heads and chiefs respectively. There was no supreme ruler who commanded control over the entire territory until the 1911 Armitage’s political integrations of states in the Northern Territories, which facilitated colonial administration of the vast lands of the north. This scheme created Sandema as the paramountcy and its chiefs as overlords of the entire Builsa up to the present. This calls for scientific research to address the question, how far did British colonial rule shape the institution of chieftaincy among the Builsa people? In addressing this question, a qualitative research approach was adopted with a content analysis strategy for the examination of the text data gathered. In addition, the researcher conducted interviews with knowledgeable persons about the evolution of chieftaincy in Builsa under British rule to complement the archival and secondary sources. Based on the evaluation of the data, the findings conclude that British colonial policies strengthened the institution of chieftaincy in Builsa and bestowed more power and authority on the Builsa chiefs. The study further argues that British rule served as a magnetic force that pulled together the dispersedly Builsa villages and towns into a unified powerful state. This growth of unity and power made the Builsa paramountcy later challenged the supremacy of Mamprugu over the Builsa territory and completely regained its independence from the Nayiri colonial-backed domination in 1933.
