The purpose of this research is to propose a new choice of nonnegative parameter t in Dai–Liao conjugate gradient method.

Conjugate gradient algorithms are used to solve both constrained monotone and general systems of nonlinear equations. This is made possible by combining the conjugate gradient method with the Newton method approach via acceleration parameter in order to present a derivative-free method.

A conjugate gradient method is presented by proposing a new Dai–Liao nonnegative parameter. Furthermore the proposed method is successfully applied to handle the application in motion control of the two joint planar robotic manipulators.

The proposed algorithm is a new approach that will not either submitted or publish somewhere.

The purpose of this paper is to investigate the relationship between corporate entrepreneurship (CE), organizational culture (OC) and business performance (BP). Additionally, the study has attempted to address the moderating influence of OC on CE–BP relationship.

Data were collected from middle managers of Big Five banks of Pakistan. A two-step approach to structural equation modeling was used. Using confirmatory factor analysis, the measurement model fit was determined. The significance of the theoretical relationship was assessed using structural model.

The results have supported the hypothesized direct and moderated relationship.

The present study extends the body of knowledge in testing the resource-based view of the firm theory and contingency theory through providing empirical evidence on the hypothesized relationships. Additionally, the study has contributed in the existing theory through evaluating the moderating of OC by using interaction effect in partial least squares structural equation modeling (PLS-SEM).

The purpose of this paper is to examine the effects of the implementation of the International Public Sector Accounting Standards (IPSAS) on Nigeria’s financial reporting quality.

The study employed a survey research design to determine the effects of the implementation of the IPSAS on Nigeria’s financial reporting quality. Partial Least Square 3(SmartPLS 3) technique of analysis was applied to achieve the research objective.

The study found that accountability positively and significantly affects the quality of financial reporting in Nigeria. Specifically, IPSAS has improved the level of accountability, which in turn improved Nigeria’s financial reporting quality.

The study only explored two explanatory variables whereas other variables such as transparency, corruption minimization, comparability and faithful representation were not considered in this study. It is, therefore, recommended that further studies could expand the scope to cover some other variables not included in this paper.

IPSAS-Accrual has engendered the Nigerian Government to launch the Asset Tracking and Management Project (ATMProject) in order to easily track its assets for the purpose of accountability. Thus, accountability was discovered in this study to be the most essential factor to enhance the quality of financial reporting using accrual-based IPSAS in Nigeria.

Accountability will impact positively on the lives of Nigerians in relation to the application of public funds to impact on the lives of the masses.

The statistical significance of accountability found in this study, using partial least square technique of data analysis, will further enhance financial integrity in the country.

The purpose of this study is to determine the level of perception of a Muslim account holder in a conventional bank toward Islamic banking products and to determine the relationship between the perception levels of Nigerian’s account holder’s and their decision to patronize Islamic banking. Personal perception factor is operationalized as opinion or observations, which are able to influence customer’s decision to patronize Islamic banking products and services.

A field survey was conducted and samples drawn using proportionate stratified simple random sampling techniques. Out of the 500 questionnaires distributed by hand, only 304 were returned and 286 were usable for the data analysis using SPSS and PLS Modeling Software.

First, the means for personal perception variable was 4.91 with standard deviation of 1.007. This indicates the good perception level of Islamic products by Muslim account holders in a conventional bank in Kano, Nigeria. The respondents’ level of decision to patronize the Islamic banking products and services was satisfactory. Second, the results also showed that the research framework model, structural model and hypothesis were supported. In the measurement model, the convergent, discriminant validity and reliability/composite reliability of the perception construct were assessed favorably. The results revealed that perception was positively associated with a Muslim account holder’s decision to patronize Islamic banking products.

The study is subject to several shortcomings that limit interpretation of findings. One of the limitations of this study is the use of cross-sectional design for survey research and subjective self-reported perceptual measures in assessing the studies. Hence, the findings of this study cannot be generalized in a larger context across the cultures of other countries.

The implication of this study is for the Islamic banking industry to focus on the people’s level of perception, government support, quality and availability of Islamic banking products and services that would have an impact on customer decision to patronize Islamic banking products. The necessary suggestions on new area of research were recommended for future researchers.

Islamic banks have the potential to exploit and market to various segments of customers extending beyond those who are concerned with the legitimacy of the facility from the Islamic point of view and those who seek service quality, convenience and efficient transactions. To the practitioners in search of patronage of Islamic banking products and services, patronage studies on Islamic banking have so far largely focused on the combination of various religious, reputation, commercial, service satisfaction, staff, confidentiality and convenience factors.

The results of the present study establish the major problem that requires urgent attention needed to strengthen public education toward the distinctive characteristics of Islamic banks and how it may profitably suit the interest of customers in their financial dealings.

The purpose of this paper is to investigate investor herding behaviour and the effect of presidential elections on investor herding behaviour in African stock markets at the sector level.

The study segregates listed firms into financial, consumer goods, consumer services and basic materials sectors and uses the cross-sectional absolute deviation approach as a metric of detecting herding in each of the sectors. The authors extend the model to tease out the effect of presidential elections on investor herding behaviour.

The study reveals that sectoral differences are fundamental to the evolution of herding. Herding is prominent in a financial services sector dominated by banks. The phenomenon also prevails in markets with smaller consumer goods and services sectors. A post-presidential election effect on investor herding is found for the consumer goods and services sectors of Ghana and a pre-presidential election effect is documented in Nigeria's consumer services sector. The authors conclude that post-presidential election effect is as a result of political connections whilst a pre-presidential election effect is attributable to political business cycles.

The study is based on four African countries due to data constraints. Nonetheless, the study is the first in Africa to the best of the authors' knowledge, and the results are very solid and have a lot of practical and policy implications.

The study has implications for investors as it guides investment behaviour in pre- and post-presidential election periods.

Past studies on investor herding behaviour in African stock markets have largely concentrated on the aggregate market. Knowledge on sectoral differences in investor herding is almost non-existent for African stock markets. Furthermore, premised on the fact that stock markets react to presidential elections, there is no known study that have attempted to examine the effect of presidential elections on investor herding behaviour. This paper contributes to the literature by providing evidence on sectoral differences in investor herding behaviour and the effect of presidential elections on sectoral herding behaviour.

This study aims to explore commonalities and differences between Islamic social finance (ISF) and sustainable development goals (SDGs).

The study has adopted a qualitative library-based research method, and the secondary data is collected through the available literature on the topic.

This study concludes that the majority of SDGs are compatible with ISF. Moreover, it finds that the global ISF possesses adequate financial resources to assist Muslim majority nations in achieving some of the most critical and urgent SDGs on time.

The scope of this study is confined to examining the possible role of ISF in achieving many of the most pressing development goals aligned with the SDGs. To maintain coherence within the study’s focus, this paper makes no comparisons between the ISF and other types of endowments/charities.

This paper outlines an agenda for the ISF-led development strategy and makes some crucial recommendations on how the global ISF might potentially lead the charge of Islamic charities in achieving the SDGs in Muslim majority nations.

This paper adds original value to the available literature on the potential of ISF and SDGs in the arena of development. The paper analyses the role of ISF in achieving the SDGs.

The sustainable development goals (SDGs) devised by the United Nations (UN) call on countries – whether rich or poor – to solve global issues, improve lives and save the planet for future generations. However, the UN predicts that between $5 and $7tn will need to be spent annually between now and 2030 to accomplish these goals, posing a major financial hurdle. Islamic social finance, if used ethically, seeks to realise SDGs through fairness, justice and equity. Thus, this study aims to determine how Islamic social finance instruments such as Zakat, Waqf, Sadaqat and Qard-hasan contribute to realising SDGs.

This study used a preferred reporting items for systematic reviews and meta-analyses-based systematic literature review. Scopus and Google Scholar were chosen for the qualitative and meta-analysis of studies. The topic was reviewed in 178 academic papers from 2000 to 2022. The required articles were analysed after careful review.

Islamic social financing mechanisms have the capacity to solve many social issues and create better welfare conditions by ensuring economic, social and environmental sustainability in line with the SDGs. Indonesia and Malaysia lead Islamic social finance research, the survey found. The review revealed that Islamic social funding can achieve 11 out of 17 SDGs. Islamic commercial finance can be used for the remaining goals. The paper highlights Islamic social funding research limitations and opportunities.

The review study shows that Islamic social finance can fill the SDG funding gap, especially considering the post-pandemic financial crisis that has increased global income inequality and social disparities.

To the best of the authors’ knowledge, this article is the first of its kind to review the potential of Islamic social financing instruments to help achieve the SDGs.

The purpose of this paper was to determine which entrepreneurial ecosystem pillars matter most in enhancing the performance of SMEs in the manufacturing sector of Uganda.

Descriptive cross-sectional survey of 310 SMEs in manufacturing sector were sampled. Stratified and simple random sampling techniques were employed because of the population’s homogenous characteristics. Data was collected using a Self-Administered Questionnaire and analyzed using SPSS and AMOS version 23.

The results indicate both institutional arrangements and resource endowments significantly influence performance of small and medium enterprises (SMEs) in the manufacturing sector of Uganda. However, institutional arrangements have a stronger predictive power on performance of SMEs in the manufacturing sector of Uganda as compared to resource endowments.

The data was cross-sectional in nature thus limiting monitoring changes in the performance of SMEs in the manufacturing sector over a long period of time. Besides, the study concentrated on SMEs in the manufacturing sector which is just subset of the industrial sector leaving other sectors like trade and services.

An empirical study on entrepreneurial ecosystem pillars in a strategic and important sector – SMEs manufacturing sector, at a micro-level, and being done in Uganda is a contribution to existing literature. This is because, most entrepreneurial ecosystem studies are largely conceptual and are normally done at macro and meso-levels targeting SMEs generally and mostly in developed countries which have completely different business environment compared with developing countries.

This paper aims to examine the concept and practice of Islamic banking in the context of a non-Islamic country such as Uganda.

Semi-structured interviews were used to elicit the strategies banks may use to ensure that the Islamic banking system is successful and to ascertain those factors that may hinder its success. Chief executive officers of business associations, heads of committees on Islamic banking and religious leaders were interviewed.

The strategies used by financial institutions in ensuring the adoption of Islamic banking are now known such as “creating awareness of Islamic banking’s mode of operation among existing and potential clients.” The findings also show that factors such as “lack of trust among clients” may hinder the success of Islamic banking.

The research findings are useful for informing the deliberations of regulators, the business community and financial institutions. The results are applicable only to those countries in the preparation stages of adopting Islamic banking services for the first time, but they could be generalized to any new product launch in any country.

This paper may help Ugandan financial institutions to design strategies that will accelerate the adoption and, ultimately, the diffusion of Islamic banking in Uganda.
