Understanding customer satisfaction and customer loyalty in banking remains critical as banks strive to attain high performance standards to justify their existence. The aim of this paper, therefore, was to determine the mediating role of customer satisfaction between its antecedent, service quality and its consequent, customer loyalty. Quantitative research method was employed to generate 850 usable questionnaires through systematic random sampling. A mediation effect investigation was done, using regression analysis to establish the interrelationships between the three study constructs. Overall, the study empirically tested and established interrelationships between the three variables in Ghana’s retail banking industry with satisfaction emerging as a strong mediator variable. Results of the study also revealed a positive and significant mediating role of customer satisfaction between service quality and customer loyalty. There were positive and significant relationships between service quality and customer satisfaction and between customer satisfaction and customer loyalty. The positive relationship between service quality and customer loyalty was insignificant. It is, therefore, concluded that, there is the need for banks to improve service quality at all levels, as the benefits to be derived are enormous, impacting strongly on customer satisfaction and weakly on customer loyalty.

DOI : 10.51244/IJRSI.2022.9402Many practical issues in science and engineering are formulated by ordinary differential equations (ODE) that require their own numerical solution. There are a variety of numerical approaches, e.g. the Euler method, the modified Euler method, the Heun’s method, the Adam-Bashforth method, and so on, that exist in the context of numerical analysis. Amongst them, the classical fourth order Runge-Kutta (RK4) technique is the most reliable and most used. The objective of this paper is twofold. The first goal is to derive the value of different parameters in the formulation of the fourth order Runge-Kutta method, and the second goal is to give details of the geometrical interpretation of this method, principally explaining the role of the increment parameters in the formula. The whole discussion will facilitate perception of the key mechanism of the Runge-Kutta method.

DOI : 10.51244/IJRSI.2022.9403Background: Heat stress exposure in the workplace that occurs continuously will affect the increment of fluid expenditure through sweat and if it is not accompanied by adequate fluid intake, it will cause dehydration. One of the workplaces that have a physical hazard in the form of heat stress is the tofu industry. Preliminary measurement results for all locations are above the threshold value limit. Method: This descriptive study uses a cross-sectional approach, the sample is 31 workers in the tofu industry, Jomblang Village, Semarang Indonesia. The variables analyzed were the amount of drinking water consumption, the habit of drinking diuretic drinks, and the incidence of dehydration. Research instruments are questionnaires, beaker glass, urinometers, and cameras. Data analysis was carried out univariately. Results: Heat stress averages 33.01°C, most workers are >40 years old (67,7%), 83.9% are male, water consumption (freshwater) averages 2,1 liter for 24 hours, and 87.1% have less water intake. 87.1% of workers have a drinking diuretic habit both at work and at home, with the most types consumed are tea and coffee. The urine specific gravity averages 1.016, a minimum of 1.009, and a maximum of 1.026 of which 58.1% is unhydrated. Conclusion: Lack of drinking water consumption to replace body fluids lost through sweat due to heat stress will increase the specific gravity of urine. The specific gravity of urine can be an early marker of kidney problems.

DOI : 10.51244/IJRSI.2022.9408In the history of the built environment, interior design and urban planning have always responded to epidemics by designing architecture and urban spaces to resist the different viruses and pathogens while preventing their spread. The architectural design strategies used in the past centuries, including Modernism, were a reaction to creating pandemic-free built forms and spaces, thus creating a healthy and sustainable built environment. The Italian piazzas, modernism, minimalism, decentralization of urban cities, urban renewal, etc. were a few of the design outcomes of a pandemic-resistant environment. This research study will help architects understand and evaluate the design strategies used to achieve a healthy, sustainable built environment, thereby adding progressive layers of protection against the virus. Future-built spaces must be designed by taking into account what we’ve learned from the past and moving in the right direction toward sustainability.

DOI : 10.51244/IJRSI.2022.9409The study reviewed the Environmental and Social Impact Assessment (ESIA) study report for the proposed highrise resort development project in Kilifi County of Kenya. The proposal by M/S Palm Exotja Limited, P.O Box 347 Watamu, will involve the construction and operation of the ultra-modern tourist facility of 61 floors- Palm Exotja Highrise Resort at Dabaso, Watamu, in Kilifi County. This will be the tallest building in Kenya and perhaps in East African region. The ESIA study report prepared by Hannah M. Njoroge, Beatrice N. Karanja and Regina W. Gathuma (Registered EIA/EA experts), on behalf of the proponent was published by the National Environment Management Authority (NEMA). Comments were invited from the lead agencies and stakeholders on environmental management, as well as from the members of the public to register their concerns regarding this proposed development project. The national heritage resources in Kenya are protected by legislation and policies and wherever they are located, usually occur as part of the natural and human environment. This study was conducted as part of this EIA study report review process and culminated in National Museums of Kenya’s raising concerns over the likely negative impact of the proposed project activities to the national heritage resources of the proposed project area. The data for this review study were gathered through literature review and fieldwork at the site of the proposed project, at Dabaso, in Kilifi County. The preliminary fieldwork carried out at the proposed project area and findings of the review of the Kenya’s national legislation on heritage management, shows that the EIA study report does not address the possible negative impact of the proposed project to heritage resources of the study area. In conclusion, the study recommends that M/S Palm Exotja Limited carries out heritage impact assessment to address negative impact of the project activities to heritage of the study area. This study has implications not only, for the decision-making regarding the integration of national heritage concerns in the national development planning processes in Kenya, but also for the professional practice in heritage management authorities, institutions and individuals such as archaeologists, biologists, anthropologists, palaeontologists and historians among others, who have interest in the management of heritage resources.

Exchange rate has become one of the major issues Nigerian economy has been confronted with in the recent times especially since one of the goals of all economies is to have a stable exchange rate. The concept of exchange rate was introduced into the analysis of economic growth and development. This study examined the impact of exchange rate on agricultural exports in Nigeria from 1981 to 2019. The Auto regressive distributed lag (ARDL) model and Granger causality test were employed as analytical tools to test for the existence of a relationship between the variables. This research generally places importance on the effect of interest rate, exchange rate, total exports, inflation rate and loans to the agricultural sector on agricultural exports. However, it is mainly concerned with the relationship between exchange rate and agricultural exports. The study establishes that exchange rate significantly affects agricultural exports and there is no causality between them. By implication, exchange rate has a direct or positive relationship with agricultural exports in Nigeria in the long run. This therefore implies that an increase in exchange rate will lead to an increase in the level of agricultural exports in the long run.

Composite breads were made by supplementing wheat flour with chemically modified African yam bean and cassava starches after the flour – starch blends were produced from the cleaned seeds and roots using hammer milling system. Three mixture components were obtained from the D-optimal mixture design of Response Surface Methodology (RSM). The physical and sensory properties of the bread was determined and subjected to statistical analysis of variance (ANOVA) using cubic models to generate the regression equations from the experimental values. The linear, binary and ternary effects of the dependent responses and their interactions was generated and graphically represented using 3D response surface plots. The developed models were tested for adequacy and validated using criterion at p<0.05, non significant (p>0.05) lack-of-fit (LoF), >0.7 adjusted R2 and >4 adequate precision to confirm adequate model signals. The numerical optimization outcomes had the desirability value of 0.86 depicting the ideal value. The optimized values for the optimum blends selected were 80.15 g wheat flour, 11.23 g African yam bean starch and 8.53 g cassava starch which will give the best composite flour -starch blends for enhanced bread products. The optimization was confirmed by performing confirmatory runs determining the 95 % confidence levels of the blends. The D – optimal mixture design of response surface methodology with three experimental components was adequate (propagated the design space) in evaluating and optimizing of the dependent responses tested; bread height, oven spring, loaf weight, loaf volume, specific volume and bulk density, appearance, crumb and crust, taste, aroma and acceptability.
