Abstract
Preservatives have been frequently used to improve the shelf life of food. The preservation of eggplants was determined using three chemical preservatives; ascorbic acid, sodium benzoate and sodium metabisulphite applied at different concentrations. The microbial load was determined to ascertain the efficacy of the preservatives. The microbiological population and diversity of the eggplant was assessed before and after treatment using standard methods. The plate count techniques was adopted to determine the total colony forming unit of the sample. Antimicrobial activities revealed that sodium benzoate inhibits the growth of bacterial and fungal species even at low concentration. Sodium metabisulphite was effective on bacteria while ascorbic acid showed a stimulatory response on the growth of fungi and bacteria. Four bacteria species namely, Staphylococcus aureus, Bacillus subtilis, Micrococcus luteus and Enterococcus faecalis and four fungal species, namely, Saccharomyces, Fusarium, Aspergillus and Rhizopus were isolated. Most of the isolates are soil and water borne which could serve as vehicle for contamination of the eggplants. Some of the isolates like Staphylococcus and Bacillus are involved in food spoilage and borne infections while Aspergillus and Fusarium species are notable causes of mycotoxicoses in man and animals. This study shows that preservatives applied at appropriate concentrations can create adequate protection from spoilage microorganisms, and therefore recommends the use of sodium benzoate to enhance the keeping quality of eggplants.

Abstract
In this study, the prediction issue of oil viscosity, on oil samples taken from Guneshli oil field of Azerbaijan has been viewed applying empirical correlations as Beggs-Robinson, Labedi, modified Kartoatmodjo, Elsharkawy and Alikhan, Al-Khafaji. The correlation models used in the evaluation of viscosity of Azerbaijan oil have been implemented in the Python software environment. The obtained values on empirical correlations have been compared to experimental data obtained from Guneshli oil field. The result of prediction has been evaluated using statistic functions as absolute average deviation (AAD), mean absolute error (MAE), correlation coefficient, root mean square error (RMSE). According to statistical analysis, it has been known that the Beggs-Robinson model has shown the lowest value on AAD (10.5614%), MAE (12.4427 %), RMSE (20.0853 %). The Labedi model has presented the worst result on every four criterions. Even though the Elsharkawy-Alikhan model has presented the highest result (99.9272%) on correlation coefficient, in the evaluation of viscosity of Azerbaijan crude oil, the Beggs-Robinson model can be considered more acceptable.
Contribution/ Originality
All authors contributed equally to the conception and design of the study.

Abstract
The study centred on participatory decision making and organizational goal attainment. This study investigated the extent to which participative decision making affects the organizational goal attainment. The study had a sample size of 136 obtained using the Cochran statistical formula. The study employed a survey research design. The instrument used for data collection was the questionnaire. The data from the responses were presented in frequencies, simple percentages. Three hypotheses were tested using the chi-square X2 and t-test statistical tools. The study found out that: Employee participation in decision making significantly improves job productivity (X2 cal = 2.554 > X2 0.5 = 0.6763); employee participation in decision, making relates to employee motivation (Fc – test = 21 .56 > ft 1 = 2.01); the policy of employee participation in decision-making is significant in organizational goal attainment (X2 Cal = 1.887 > X2 0.5 = 0.6763) The study, based on the above findings, concluded that for the goal attainment of any organization to be achieved successfully depended on the extent to which the organization integrated the workers into the policy formulation and implementation. The study recommends that organizations should adopt the ring show management theory as a way of survival.
Contribution/ Originality
This study is one of the very few studies which have investigated employees’ participatory decision making and organisational goal attainment. Currently there are paucity studies in Abuja that examine organisational goal attainment. This study contributes an important additional dimension in the search for sustainable organisational goal attainment in Nigeria.

Journal: International Journal of Chemistry and Materials Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The current research presents corrosion inhibition activity of expired Fluoxymesterone drug on the mild steel (MS) in the 3 M HCl solution. The atomic absorption spectroscopy, Tafel polarization and AC impedance spectroscopy studies have been done to verify the corrosion protection efficiency. The surface studies were carried out by scanning electron microscopy (SEM) technique. Atomic absorption spectroscopy results show that, the amount of iron content is low in the presence of corrosion inhibitor when compared with bare system. Tafel plots clearly hint the mixed corrosion inhibition property (inhibition of both anodic and cathodic corrosion process) of expired Fluoxymesterone drug over the MS surface in the acidic environment. From the AC impedance spectroscopy technique, it is observed that, the charge transfer resistance values enhances with a rise in the concentration of the corrosion inhibitor. Surface studies by SEM also support the atomic absorption spectroscopy, potentiodynamic polarization (Tafel plot) and AC impedance spectroscopy results.

Abstract
The innovation of glucometer has set a benchmark to restrain the effects of diabetes. Diabetes is a scourging metabolic disorder, responsible for disabilities and anachronistic deaths among mass populations. The hyperglycemic condition creates physiological and psychological sufferings to the patients. These complications have led to drastic evolvement in the diabetes diagnostic technologies. The pioneer work in the field of glucose monitoring devices started with the development of blood-based sensing practices, extensively used by the patients but it is an invasive technique which induces trouble in the subjects. Thus, a non-invasive, painless method of glucose testing is a new advancement in the range of glucometers and would profoundly increase the compliance and overcome complications. Saliva-based glucometers is a non-invasive approach, has the potential to exceptionally overcome the discomfort brought up by the blood-based invasive methods. The objective of presenting this review is to provide the chronological series of events in the identification of the disease along with the technological advancements in the glucose monitoring devices.
Contribution/ Originality
This study contributes in the existing literature about the glucose monitoring technologies available in current use as well as the upcoming technologies which will add the comfort and painless methods for glucose testing to support patient care.

Abstract
This is a qualitative paper which is to present the facts and literature findings on the causes of good governance practice in Ghana conceptually. It is noted that discipline and probity are the backbone of good governance. Every country in this modern era want to achieve good governance so that there will be improvement in the economic fortunes but this cannot be achieved if there is lack of discipline and lack of probity in the practice. Hence, literature reveals that there are some relationships between discipline (independent variable), probity (mediating variable) and good governance (dependent variable). Good governance is the main important factor to eradicating poverty and advancing development, said by the UN former Secretary General – Kofi Annan (Court, 2001). This research is purely a conceptual research and a model/conceptual framework has been proposed for future scientific research. Hypothesis has been proposed which need to be developed and tested for effective and efficient conclusion in future findings as such. This research only proposes the concepts that are associated with good governance practice – discipline and probity; the methods used are the secondary sources of data findings were analyzed. Future research findings, analysis and recommendation is eminent on this proposed concept model for future researchers. Therefore, a strong methodology is needed to support all the findings and interpretations of the hypothesis. In this instance, quantitative and qualitative study as a mixed method would be suitable for future research to test relationships and hypothesis that are been identified in the proposed conceptual model.
Contribution/ Originality
The aim of this conceptual paper is to contribute to the burning issues of the lack of discipline and probity as a deterrent in the developing world from achieving good governance. This study contributes in the existing literature of the concepts needed in practice to improve good governance for development.

Abstract
This study examines the factors influencing students’ under-performance in an advanced financial reporting course. Specifically, this study examines four factors which may influence the accounting students’ under-performance in an advanced financial reporting course, namely class attendance, curricular activities, internship experience and English language proficiency. This study conducted a questionnaire survey on 83 final year accounting students who had failed the advanced financial reporting course at least once. The results indicated that class attendance, curricular activities and internship experience are associated with students’ under-performance in this course. However, English language proficiency is not a significant factor influencing students’ under-performance in the advanced financial reporting course. This indicates that understanding the content rather than the language used to teach the course is more important for student success in this field. However, further analysis shows that English language and curricular activities are significant factors for success in the advanced financial reporting course when regressed with other factors. These findings could assist academics in understanding the factors influencing students’ under-performance in the advanced financial reporting course and subsequently help develop strategies to improve results in the classroom.
Contribution/ Originality
This study contributes to existing literature on the importance of class attendance, curricular activities, internship experience and English language proficiency on accounting students’ performance in the advanced financial reporting course.

Journal: International Journal of Business, Economics and Management

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This study examined the contemporaneous effect of global economic policy uncertainty on Nigeria’s export earnings, using Nigerian data that spans from 1997 to 2016. The theoretical framework relied on the contemporaneous theory of external vulnerability, which posits that macroeconomic shocks from dominant economies could be transferred to lesser dominant economies through international linkages of global economies and financial market. To achieve objective, this study employed the ARDL and GARCH estimation techniques, to estimate the effect of global economic policy uncertainty on Nigeria’s export earnings. The results revealed the adverse effect of global economic policy uncertainty on Nigeria’s export earnings, affirming the vulnerability of Nigeria’s export earnings to external shocks. The practical implication of the finding is that developing economies could insulate their domestic macroeconomic environment from external shocks by diversifying their economies. Importantly, Nigeria should increase diversification of her export base as a coping strategy for protecting against the contemporaneous effect of global economic uncertainties.
Contribution/ Originality
The study contributes to existing literature focusing on export earnings, which is a major source of vulnerability to external shocks in Nigeria. The use of global economic policy uncertainty index appears novel, compare to previous studies that use global output and inflation.

Journal: International Journal of Business, Economics and Management

Export to    BibTeX   |   EndNote   |   RIS

Abstract
In this research, we study factors such as consumer attitudes and personal innovativeness in order to understand the effect of loyalty on satisfaction with mobile wallet applications in Thailand. We developed a research model, based upon previous research, where we propose and examine four constructs. In general, consumer attitudes and personal innovativeness loaded strongly on both loyalty and satisfaction with the Thai consumers sampled. We found strong support for all of the hypothesized relationships, albeit some at different strength levels. It was found that consumer attitudes are an extremely strong factor that increases loyalty and improves satisfaction with mobile wallet applications in Thailand. We also found a very strong impact of satisfaction on loyalty with Thai consumers. This study helps to understand how specific factors influence consumer satisfaction with mobile wallet apps, and what drives consumers’ decisions to be loyal and satisfied customers.
Contribution/ Originality
This study contributes in the existing literature of consumer behavior, particularly consumer satisfaction model. This study uses new estimation methodology of survey construct with snowball sampling approach. This study originates new formula for predicting Thai consumers’ satisfaction in mobile wallet usage. This study is one of the very few studies which have investigated in factors influencing the satisfaction with mobile wallets apps. The paper’s primary contribution is finding that consumer attitudes has a significant influence on Thai consumer loyalty and increase satisfaction.

Journal: International Journal of Sustainable Agricultural Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Poultry feed cost represents a significant part of operational cost of poultry production. Consequently, efficient feed formulation practice is required for a sustainable poultry production. Many poultry farmers, employ inefficient methods like rule of thumb and intuition to handle feed formulation problem. This paper presents the report of the development of a feed formulation model which can be used to harness the potentials of locally available feed stuffs toward producing a balanced poultry feed. To achieve this aim, a hybrid Tabu-Genetic Algorithm Model ((TAM) was developed for layers mash feed formulation as case study. Thirteen (13) decision variables and eight (8) constraints were identified and used in the research. Secondary data were collected from the recommended nutrient requirements schedule made available by both the Ondo State Ministry of Agriculture and the Freedom Feed Mill (a local feed miller) in Akure, South-West Nigeria. Based on this data, the optimal solution of the TAM developed for the layers mash produced a balanced feed at reduced cost.
Contribution/ Originality
This study uses a hybrid of tabu search (TS) and genetic algorithms (GA) to formulate poultry feed. GA being a global search algorithm is usually slow. The introduction of TS helps to reduce the time taken to arrive at the optimal solution.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
It is argued that while increase in budgetary allocation to social services is highly desirable, it is not sufficient to guarantee enhancement in better health outcome. This paper links public health expenditure, economic growth and health outcomes and the causality among them using Nigeria data. The finding suggests increase in public health expenditure has decreased infant mortality rate while infant mortality rate is negatively correlated with economic growth. Interestingly, the direction of causality among public health expenditure, infant mortality rate and growth is unidirectional, from public health expenditure to growth.
Contribution/ Originality
This is one of the few studies which have investigated public health expenditure, economic growth and health outcomes (infant mortality rate) in Nigeria.

Journal: Journal of Social Economics Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The study analyzed the linkages among food security, nutrition and health care outcomes within the SADC regional bloc for the period 1991 to 2016. The study employed panel OLS and quantile regression analysis and the latter provided more informative findings that would culminate in the development of effective policies to deal with problems of infant mortality. Specifically, the study showed that population growth and malnutrition have a positive and significant effect on infant mortality across the entire distribution. The effect of investment in fixed capital and economic development is significant at higher quantiles. There is a non-linear relationship between infant mortality and population growth. Food security has no effect on infant mortality rate across the entire distribution and these results are consistent with those found using panel OLS. Robust results using quantile regression show that the sensitivity of infant mortality to each variable remains the same, statistically, but the magnitude or effect increases in higher quantiles. The study showed potential parameter heterogeneity across countries with implications for estimating the wider effects of mortality for a policy shock that may have unequal effects across the distribution. Properly developed policies should have a differentiated approach in influencing the rate of infant mortality in member states.
Contribution/ Originality
The study is one of the few studies that have examined the linkages among food security, nutrition and health care using quantile regression in SADC.

Journal: Journal of Information

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The purpose of this study is to identify the factors that affect the behavioural intention to use mobile apps by Gen Y in Malaysia. The Unified Theory of Acceptance and the Use of Technology 2 (UTAUT2) and the Diffusion of Innovation Theory (DIT) are combined to examine the drivers that affect the behavioural intention to use mobile apps. The factors include performance expectancy, habit, price value, social influence, complexity and trialability. Data was collected by distributing self-administered survey questionnaires using the quota sampling technique to Gen Y in five States in Malaysia. The results show that all these variables significantly affect the behavioural intention to use mobile apps by Gen Y in Malaysia. The UTAUT2 and the DIT have been proven to be the suitable theories that can be considered by future researchers who wish to conduct research related to technological innovations. This study is useful for apps’ designers, as they will be able to design apps to suit users’ preferences and expectations by analysing the variables.
Contribution/ Originality
This study combined UTAUT2 model and Diffusion Innovation Theory to study the behavioural intention and confirmed their suitability. Any future researchers on technological innovation can use this new model. Additionally, this study is useful for apps’ designers to design apps to suit users’ preferences by understanding the influencing factors.

Abstract
In teacher education, action research has served as one of the tools for reflective practice to bridge the gap between the educational theories learned in the teacher training college and the actual pedagogical practice within the four walls of the classroom. In this descriptive and explorative research study, first the concept and characteristics of action research are outlined, supported by a discussion on action research types and models that are relevant to teacher training in Malaysia. Then, this paper explored the implementation of action research component in teacher education in Malaysia by first providing brief background information of action research in Malaysian teacher training institutes. Then, it discussed issues and challenges that are faced in terms of curriculum, teaching methods and objectives. The study also discussed the rationale for integrating action research component in teacher education programme. The result shows that the implementation of action research is hampered by the absence of exposure to action research in the earlier part of the training, the curriculum lacks practical input and the objectives set can be general and vague. It is recommended that action research workshops and trainings are conducted earlier in the training program and that more hands-on learning experience is introduced.
Contribution/ Originality
This article contributes to the existing literature by providing an overview of action research implementation in teacher education system in Malaysia. It discusses the issues and challenges that are faced by action research supervisors and trainee teachers. It also highlights the rationale for integrating action research component in teacher education curriculum.
