Fractional calculus and applications of family of extended generalized Gauss hypergeometric functions

The aim of the present paper is to establish certain new image formulae of family of some extended generalized Gauss hypergeometric functions by applying the operators of fractional derivative involving 2F1(.) due to Saigo. Furthermore, by employing some integral transforms on the resulting formulas, we obtained some more image formulas and also develop a new and further generalized form of the fractional kinetic equation involving the family of some extended generalized Gauss hypergeometric functions and the manifold generality of the family of functions is discussed in terms of the solution of the fractional kinetic equation. The results obtained here are quite general in nature. � 2020 American Institute of Mathematical Sciences. All rights reserved.

A fractional model for predator-prey with omnivore

We consider the model of interaction of predator and prey with omnivore using three different waiting time distributions. The first waiting time is induced by the power law distribution which is the generator of Pareto statistics. The second waiting time is induced by exponential decay law with a particular property of Delta Dirac distribution when the fractional order tends to 1, this distribution is link to the Poison distribution. While the last waiting distribution, induced by the Mittag-Leffler distribution, presents a crossover from exponential to power law. For each model, we presented the conditions under which the existence of unique set of exact solutions is reached using the fixed-point Picard's method. Making use of a recent suggested numerical scheme, we solved each model numerically and some numerical simulations were generated for different values of fractional orders. We noticed a new attractor which can be considered as a combination of the Brownian motion and power law distribution in the model with the Atangana-Baleanu fractional derivative. With the aim to capture more attractors, we modified the model and presented also some numerical simulations. Our new model provides more attractors than the existing one even for fractional differential cases. We presented finally the Maximal Lyapunov exponent and the bifurcation diagrams. The comparative study shows that modeling with non-local and non-singular kernel fractional derivative leads to more attractors as this kernel is able to capture more physical problems. � 2019 Author(s).

Fractional optimal control dynamics of coronavirus model with Mittag�Leffler law

Most countries around the world are battling to limit the spread of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2). As the world strives to get an effective medication to control the disease, appropriate control measures for now remains one of the effective measures to reduce the spread of the disease. In this study, a fractional optimal control model is formulated in Atangana-Baleanu-Caputo derivative sense. The reproduction number and steady state of disease free of the Coronavirus model are examined and found to be globally stable. The existence and uniqueness of solution of the fractional Coronavirus model is established by using the Banach fixed point theorem approach. Three controls are considered in the model and Pontryagins Maximum Principle is used to establish the necessary conditions for optimal control solution. The numerical solution suggests that the best strategy is found to be the utilization of all three controls at the same time. � 2020

Fractional order modelling of Anthrax-Listeriosis coinfection with nonsingular Mittag Leffler law

Anthrax and Listeriosis are both bacteria infections that affect the human system in different ways. This study, analyses a fractional order model of Anthrax-Listeriosis coinfection. The model is a modification of the integer order model formulated by Osman and Makinde in [1]. The positivity, existence and uniqueness of the model solutions are investigated by applying the definition of the Atangana-Baleanu (AB) operator in the sense Louiville-Caputo to the model. The Hyers-Ulam stability analysis is carried out and the model is proven to be Hyers-Ulam stable. The Adams-mouton scheme for the proposed (AB) coinfection model is derived and used to numerically simulate the theoretical results by varying fractional orders to see how changes in the fractional order derivative affects the coinfection dynamics. The results obtained are in agreement with the results obtained in the corresponding integer model by Osman and Makinde, however, the results reveal that the fractional order is the main driver of the coinfection and that the use of the ABC operator and fractional operators in general enhances a better description of biological processes than integer order operators. � 2022

A fractional order optimal 4D chaotic financial model with Mittag-Leffler law

In this paper, a fractional 4D chaotic financial model with optimal control is investigated. The fractional derivative used in this financial model is Atangana�Baleanu derivative. The existence and uniqueness conditions of solutions for the proposed model are derived based on Mittag-Leffler law. Optimal control is incorporated into the model to maximize output. The Adams�Moulton scheme of the Atangana�Baleanu derivative is utilized to obtain the numerical results which produce new attractors. Euler-Lagrange optimality conditions are determined for the fractional 4D chaotic financial model. The numerical results show that the memory factor has a great influences on the dynamics of the model. � 2020 The Physical Society of the Republic of China (Taiwan)

Fractional stochastic modeling: New approach to capture more heterogeneity

To further capture holding complexities of nature that arise in many fields of science, technology, and engineering, we suggested in this paper a novel approach of modeling. The novel approach is a coupling of fractional differential and integral operators with the stochastic approach. The approach is texted using systems of chaotic problems. The numerical simulation impulsively shows that the new approach is able to capture hiding behaviors that could not be captured by fractional differential and integral operators and the stochastic approach only. We believe that this approach is the future way to model complex problems. � 2019 Author(s).

Frames of poverty, a qualitative content analysis of selected newspapers in Ghana

Poverty has remained a cancer that plague many developing countries and the media have a role to play in eradicating poverty. This study examines the prominence the media give to issues of poverty, the frames used by the Daily Graphic and the Ghanaian Times newspapers to report issues of poverty and the reasons for using these frames from the perspective of journalists. Newspaper content analyses and interview are the methods used to collect data for the study. Premised on the agenda-setting and framing theories, contents of the two state-owned newspapers, published from January to December, 2019 were analysed, and 263 poverty-related stories were identified. The analyses of these stories revealed that the media in Ghana give little prominence to issues of poverty in comparison with the frequency and placement of poverty-related stories in the newspapers. Four frames – poverty redress, poverty advocacy, plight of the poor, the poor as nuisance – emerged from the data analysed. Thus, the newspapers dominantly frame poverty as a phenomenon that is being addressed, and advocate for its address. Journalists argued that the sources of poverty news, economic reasons, personal values of journalists and media as mirror of society are the dominant reasons these frames are used to report issues of poverty. The study recommends, therefore, that the media pay more attention to and report issues of poverty, especially when poverty remains a plague that hangs on the neck of the majority of Ghanaians.

Framework for assessing the performance of the Ghanaian health system: study protocol

Background: Assessing the performance of health systems through quantitative and qualitative methods is recognized as an effective approach to strengthening national health systems. However, while many high-income countries have institutionalized health system performance assessment (HSPA) as an integral component of their respective health systems, few studies on HSPA have been documented in low- and middle-income countries, including Ghana. This study aims at providing a comprehensive framework for periodic assessment of the performance of the entire health system in Ghana. Methods: The study will have four work packages. First, a structured review will be conducted to identify both international and national HSPA frameworks that could be applied to the Ghanaian context. Second, based on the structured review, an assessment framework tailored to the Ghanaian health system context will be developed. Third, the draft framework will be presented and discussed with experts and stakeholders for its appropriateness, feasibility and acceptability. Finally, the framework will be piloted to assess its effectiveness and suitability for full-scale implementation. Discussion: Currently, Ghana does not have a full-fledged HSPA tool that provides a holistic health sector-wide approach to assessing health system performance. Thus, developing this HSPA framework for the country will provide a tool for periodic and comprehensive assessment of the performance of the health system, which can be compared with that of other countries. Such a comparison will offer the opportunity for mutual learning and for exploring new options for formulating more effective national health policies. As this is expected to be the first attempt to develop a comprehensive HSPA framework in Ghana, this study will provide a basis for future discussions on how to further develop and implement HSPA programmes in the country. � 2021, The Author(s).

A framework for designing and producing academic gowns for Technical Universities in Ghana

The academic gown literature in Africa is limited due to a lack of research on design histories, philosophies, aesthetics, gown wearer perspectives, and framework for producing academic gowns for Ghana's technical universities. The study therefore sought to develop a framework for academic gown production for Ghanaian technical universities by investigating the design histories, philosophies, aesthetics, and perceptions of academic gowns. The study used expert and maximum variation sampling techniques to select 66 participants. Using an inductive approach and a qualitative research design, the study employed a multi-method data gathering strategy, and narrative analytical techniques were used for data analysis. The study revealed that technical universities initially hired gowns for academic ceremonies, but between 2000 and 2011, they started producing their own gowns incrementally due to high rental costs, identification issues, and income generation. While some designed and constructed their gowns in-house, the majority subcontracted to gown contractors. Institutions, apart from management, still hire gowns for members to supplement their existing collection and then rent out their own gowns to interested institutions. Whereas some institutions incorporate their philosophies into the gown designs to ensure corporate identity, others do not. The institutions often designed the gowns to be aesthetically pleasing, and the designs have expressive, political, sociocultural, economic, and emotional implications. 41.7% of participants were satisfied with their gown designs, 35.4% were dissatisfied, and 22.9% were somewhat satisfied, with 58.3% expressing a desire for improvement. Consequently, the study developed a seven-stage design framework after validating the five-stage framework, which is now suitable for gown design and production. Wearers value highly academic gown use for ceremonies, and customising them can enhance their identity and brand image. Therefore, academic institutions should adopt the framework for academic gown production. For research and educational purposes, technical universities should maintain detailed information about gown designs for research and educational purposes.

A framework for developing ICT policy for tertiary institutions in Ghana. The case of Ghana institute of languages

Information and communication technologies play an important role in reshaping education to respond to current and contemporary information society needs and to reduce the gaps that exist between socio-economic realities. The purpose of this study was to establish the framework for developing ICT policy for tertiary institutions in Ghana with reference to the Ghana Institute of Languages as a case study. This study was guided by the following specific objectives: to identify the benefits and challenges of developing the ICT policy for tertiary institutions in Ghana; to determine the ways in which the ICT policy could be integrated into the teaching and learning process by lecturers and students; and to determine the extent to which the implementation of the ICT policy for tertiary institutions can reach A survey research design method was used for this study. The study population consisted of 50 lecturers and students. A sample of 35 was drawn using a simple random sampling technique from the list. The data was collected by the use of a questionnaire. The study proves to be of immense benefit, although it may encounter challenges, which are a common phenomenon with most such programs. However, with the overwhelming advantages expected to be achieved, there is a need for tertiary educational institutions to embrace the concept no matter what may serve as an obstacle. Also, it would lead to online education, which would improve students’ intake and give more access to both teachers and learners, thereby easing the pressures of the traditional face-to-face teaching and learning process. Furthermore, it was also concluded that the integration of the ICT policy framework should be on a pilot basis so that strengths and weaknesses would be identified and resolved before spreading to the other institutions. Additionally, capacity building should be established using the teachers who are considered cardinal points and the centre for the entire implementation of the policy University of Education,Winneba http://ir.uew.edu.gh xiii framework. The study recommended that in order to successfully integrate the ICT policy framework, there is a need to run the programme on a pilot basis in order to identify its strengths and weaknesses before generalization.

Framing of corporate social responsibility (CSR) initiatives

This research was initiated to be an information source for the researcher to appreciate the state of CSR initiatives in Ghana as are portrayed in the Ghanaian newspapers with particular reliance on the Daily Graphic. The objectives of the study included examining the coverage given CSR initiatives and the types of CSR initiatives that are reported on in the Daily Graphic as well as identifying the dominant frames through which the CSR initiatives are narrated. Designed as a qualitative content analysis study, the research used document analysis to answer the research questions. The research found that the Daily Graphic did not give prominence to CSR initiatives in its coverage. Most CSR issues reported in the Daily Graphic centred more on philanthropic, ethical as well as economic initiatives. The research further found that poverty, health and sanitation, education, development, and stakeholders frames were the major frames used by the newspaper to report the CSR initiatives. The findings of this research will help organisations know the kind of CSR initiatives that the Daily Graphic reports on and how this reportage is done so they can make a conceited effort to be more involved in the narrative about their CSR activities.

Framing of female athletes in Ghana, a study of two selected newspapers

This research examines how female athletes in Ghana are framed by local sports newspapers and investigates the perceptions of the female athletes towards the frames used. The study was based on the framing and feminist theories. The study used qualitative method for the data collection and analysis. Two major local sports newspapers with the highest circulation- the Graphic Sports and the 90 Minutes were selected for the study. In addition, interviews were conducted with six female athletes to complement the analyses of stories from the newspapers. The major findings in this research revealed that the field of sports is clearly a gendered profession that not only welcomes men enthusiastically than women but also serves as a site for celebrating skills and values clearly marked as masculine. This study also showed that female athletes are often overlooked and marginalised as they are deemed inferior in skills and knowledge to their male counterparts. Furthermore, the study showed that, in the area of sports, women are treated as “outsiders” by virtue of their gender but “insiders” by their adherence to athletic norms and values. The study concludes that men in Ghana continue to dominate and have all the authority in the field of sports and this eventually leads to the underrepresentation of women in the profession.

Framing of the xenophobic attacks in South Africa by the BBC and Al Jazeera online newspapers

This study examines how the BBC and Al Jazeera Online newspapers framed the xenophobic attacks in South Africa. The study is underpinned by the Framing Theory. Data were gathered from 32 news and feature articles by the BBC and 63 by Al Jazeera Online newspapers. These were thematically analyzed. The findings reveal that the attribution of Responsibility frame is the most dominant. This was followed by the frames of Human Interest, Economic Consequence, Conflict, and Morality in the order of importance. Also, it was revealed that the African immigrants in South Africa were depicted as Targets and Competitors of the local South African. The findings also show that the two online newspapers used negative tones in describing the South African but are slightly positive towards the African immigrant. The study concludes that the BBC and Al Jazeera Online newspapers impute responsibility for the attacks to the South African people who see the African immigrants as the cause of the economic frustration of the South African. It is recommended that news makers minimize framing players of migration crisis in a negative light in order to better mediate in migration related crisis and avoid stirring violent confrontations between immigrants and local populations.

From students’ pop band to a trans-african international band: A historical case study of Ghana Bigshots Band

The purpose of this study was to construct a concise historical narrative of the formation, development, survival and internationalisation of the Ghana Bigshots Band. It is quite unusual for a pop band to emerge from a Ghanaian university and still survive after school, considering both the academic and industry challenges. The Ghana Bigshots Band, arguably Ghana’s first modern ‘Afro-fusion’ band emerged from a university and came to international prominence. The band has broken the myth of the ‘ivory tower’, where the academia disassociates itself from the realities of the society. Employing interview and documentary research for data collection, the paper consequently unravels that the transition from students’ pop band to a trans-African international band was capital intensive. However, the consistency of maintaining an African identity in the band’s compositions and the ideology of blending tradition and modernity accounted for its survival and internationalisation. This study, is, therefore, recommended as a roadmap for student-musicians who wish to take their craft beyond the academic enclave.

Fruits and vegetable consumption trends among basic school students in the Kwadaso Municipality Ashanti Region of Ghana.

In Ghana and more specifically, in the Ashanti Region, regardless of the abundance of fresh fruits and vegetables and numerous efforts by government and other stakeholders to encourage the consumption levels among school-aged children and adults, very little has been achieved. Generally, several factors such as socio-economic and socio-cultural factors, food costs, taste, convenience, and availability are known to influence the consumption of fruits and vegetables. The specific objectives sought to, assess the influence of knowledge of fruits and vegetables consumption on the consumer, evaluate the postharvest handling methods used by students in the postharvest management of fruits and vegetables; and their challenges. The study utilised the quantitative and descriptive research approach. The researcher used simple random sampling to select 120 participants for this study from the various schools in the community. The researcher used observation and questionnaire to collect data from respondents. Descriptive statistics such as frequencies, percentages and means were used to analyse the data collected. The population for this study covers the entire adult population residing in the Kwadaso Township who are aged 12 years and above. The population is estimated to be about 2000 according to the Ghana Statistical Service. This includes both males and females, educated and uneducated. The study also revealed that students conveyed their fruits and vegetables usually in polythene bags and jute sacs. It was also noticed that, the method of conveying was dependent on how longer or shorter the distances under consideration. Most of the losses that were recorded in fruits and vegetables consumption were mainly during the storage stage and in the course of transit. Most of the labour or workforce for the production of fruits and vegetables were aged people. The study recommends that partly prepared fruits and vegetables could be prepared for students who are unable to consume due to their busy schedules so that they could carry them along in order to increase their consumption.
