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.

Research Article
Author(s): Richardson Kojo Edeme, Oluchukwu Olisakwe
Journal: International Journal of Public Policy and Administration Research

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.

Health Care Outcomes, Malnutrition and Food Security in Southern Africa Development Community: A Quantile Regression Approach

Research Article
Author(s): Strike Mbulawa
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.

Journal: International Journal of Education and Practice

Export to    BibTeX   |   EndNote   |   RIS

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.

Abstract
Vitiligo, an asymptomatic de-pigmenting skin disease occurs in both males and females. It is not readily known if differences in clinical and socio-demographic features exist between male and female vitiligo patients. To document gender based differences in socio-demographic (age at onset, area of onset, family history of vitiligo) and clinical characteristics (type of vitiligo, severity of disease, activity of lesions, area affected) of adult Nigerian vitiligo patients. This was a retrospective cross-sectional study of 76 adult vitiligo patients who attended the Dermatology Outpatient Clinic of the University College Hospital, Ibadan from January 2005 to December 2009. A questionnaire designed for the study was used to document the relevant information. Data was analyzed using SPSS version 16. Prevalence of vitiligo was 4.5%, 44 males (57.9%) and 32 females (42.1%) were seen. Mean age at onset was 34.6 ±17.1 years with a range of 1-78 years. The face and scalp were the commonest areas of vitiligo occurrence in both genders. There were differences in clinical characteristics however, they were not statistically significant. Significate difference was found in level of education, self-medication and duration of disease. There are some differences in clinical profile between male and female adult vitiligo patients.
Contribution/ Originality
This study contributes to the existing literature on vitiligo in adults. Vitiligo occurs in both adult males and females. However, differences in clinical and epidemiologic features of vitiligo between males and females is not readily documented. This study highlights these differences.

Journal: Humanities and Social Sciences Letters

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Knowledge-management (KM) has received much attention because of the rapid growth of computers and information technology in shaping products and services. While new learning and innovations added value to the existing products and services, they also added a new dimension to economy, popularly coined as knowledge-based economy. The 21st century is often described as an era of “knowledge capitalism.” This study has attempted to find links between KM practices and modern education and learning. This study has shown how KM practices can be used for education, training and learning purposes which in turn can help organizations leverage the skills and expertise of their workers and transform them into knowledge capital. This study also aims to identify such KM practices that create a knowledge economy. Data has been collected from six universities in public and private sectors in Saudi Arabia where KM practices can be seen and which have contributed to the national economy.
Contribution/ Originality
This study is going to be a useful contribution to the domain of knowledge economy in the Saudi Arabian context, particularly when the country is looking for a non-oil based economy, pursuing the 2030 vision. This study shows how learning and KM practices build up a knowledge economy.

Journal: Review of Information Engineering and Applications

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Traffic signs, signals and road markings installed on the roads and highways need a lot of improvements in Pakistan. They do not fulfill the fundamental conditions as per international standards i.e. peculiar shapes, sizes and colors. Among all the reasons the most important being the lack of a proper Manual, outlining the warrants and other details essential for putting up proper signs. The problem is further being made worse by the lack of qualified traffic engineers, not fully familiar with the art and science of traffic signs. As a result, the field engineers and contractors were left to their own wishes with regard to design and installing of the road signs. Where as in developed countries there are many signs manufacturing firms who are specialized in this particular field. Many international organizations making efforts for the uniformity of markings and road signs in order to improve the safety of roads and to enhance international roads traffic, but in Pakistan not much significant work has been done and is still very much lagging in this industry. This study is aimed to investigate about the improvements that need to be done in traffic signs and markings, there installation and their maintenance. This will help to make the traffic flow more safe and efficient. The up short of all this study is to enhance the best possible safety of the road users by awaking and changing the aptitude and attitude of users towards the traffic control devices.
Contribution/ Originality
This study contributes in the existing literature by suggesting improvement measures for traffic control devices used on rural highways in most of developing countries in terms of its manufacturing, installation and maintenance and also the road users response that can be enhanced by taking these measures.

Abstract
Hot pepper (Capsicum annuum) is an economically and traditionally an important crop in Ethiopia. It is also necessary vegetable crop mainly for small-scale farmers in Amhara National Regional State of Ethiopia. The productivity of this crop is low under national level, it is said to be 7.36qt per hectare. It is even lower to that of the national in Amhara National Regional State growing areas. Assessing pepper growing areas and collect damaged plants by the disease and identification of diseases was the focus of this study. Three districts were selected purposively based on accessibility, production and problem, available time, logistics, and representativeness. In each district three representative peasant administrations (PAs)/kebeles were selected. Sampled kebeles and respondents were selected using simple random sampling techniques. A total of 135 respondents were selected for interview. The data was collected through semi structured interview schedule. In each PA, three simple random sample selected farmers’ fields were assessed. The assessment was done at one growth stage of the plant (flowering-podding stage). The collected data was analyzed using descriptive statistics. The findings of this study confirm that in all the surveyed peasant farms, only one type of variety, which is Marekofana was encountered with low to high levels infestation of different leaf, stem, and root diseases. Root rot/wilt complex diseases were found distributed in almost all the surveyed areas. The prevalence of the disease, pepper wilt/root rot complex is high, therefore; efforts better to be made towards the integration of multiple control options.
Contribution/ Originality
This study contributes in the existing literature to fill the gap of the current state of knowledge of pepper disease assessment and identification. This study is one of very few studies which have investigated pepper disease assessment and identification. The paper contributes the first logical analysis of pepper disease.

Journal: International Journal of Business, Economics and Management

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This paper examines external debt and economic growth relationship in a panel of 48 Sub-Saharan Africa countries (SSA) for the period 1990-2017 using a two-step system General Method of Moments (GMM) technique. Our study shows that contemporaneously, external debt has a negative and statistically significant impact on GDP growth. However, the first lag of external debt variables stimulates GDP growth. The implication is that external debt accumulated in the previous period makes funds available for growth enhancing expenditure in the next period. Furthermore, our study found no evidence of a non-linear relationship between debt and economic growth. Lastly, we found that the deleterious impact of external debt on GDP growth does not preclude poor or rich SSA countries. We recommend the adoption of state-of-the-art measures in collecting domestic revenue to complement external revenue sources. In addition, we advocate for strong macroeconomic environment in SSA so that yield negotiation on the debt will not dissipate the coffers of SSA countries via high debt servicing cost.
Contribution/ Originality
This study uses new estimation methodology to unravel the external debt and economic growth nexus in Sub-Saharan Africa countries.

Journal: Humanities and Social Sciences Letters

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Teacher education is an important pillar of every education system worldwide. Consequently, there is a need to determine the efficacy of teacher education programs in preparing good-quality teachers. The aim of this study is to investigate the impact of learned media and teaching skills on the teaching of mathematics in secondary schools. We therefore explore how secondary school mathematics teachers perceive the effect of “media practicals” and “microteaching” on teaching practice through a survey study. Seventy respondents provided usable data for the analysis, which indicated that media practicals are well organized and microteaching helps the majority of student teachers practice the various teaching skills they had learned. However, the majority of respondents (61.4%) stated they were not able to implement all the techniques they learned during their teacher training, while most respondents’ (57.1%) teaching practice sessions were only assessed once by their supervisors. A major recommendation is that teaching practice assessment should be emphasized and undertaken at least twice.
Contribution/ Originality
This study contributes to the existing literature and discourse on the effectiveness of teacher education programs, with a focus on the reform agenda. Media practicals and microteaching are two main components of teacher education that have a strong bearing on the quality of teachers in imparting knowledge, competence, and attitudes to the youth of any state or country.

Research Article
Author(s): Nan Yin
Journal: International Journal of Management and Sustainability

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Organizational justice has long been the focus of research in the field of organizational behavior. In general, organizational justice is the subjective evaluation and perception of employees towards allocation of resources, rewards and punishments, performance evaluation, decision-making process and the interaction with the supervisor. Many studies show that organizational justice has a significant impact on employee attitudes and behaviors. To be clear, the main objective of this study is to explore whether the organizational justice the employee perceived will affect employee’s job satisfaction and organizational citizenship behavior. This study takes the real workplace environment as the target, with the actual staff as the sample, using the small and medium-sized computer and computer parts sales companies in Nanjing, China as the subject. In this study, 48 companies were randomly selected through field visits, the test object being the staff engaged in sales business in 48 computer and computer parts sales companies. The results show that there is a positive relationship between organizational justice and organizational citizenship behavior, and that job satisfaction has partial mediating effect on the relationship between organizational justice and organizational citizenship behavior.

Journal: International Journal of Management and Sustainability

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Supply of some materials and metals in the World is getting increasingly challenging. To deal with this issue, several organizations (e.g. European Commission) have composed a list of materials critical for the economy, in the list, 27 critical materials (CMs) are included. Furthermore, several actions have been proposed to tackle the problem, including recycling of CM from secondary sources. Global supply chains of raw CMs often rely on limited number of suppliers (e.g., China, Russia, Brazil, US). Since some countries have monopoly and regulate the supply of CMs, they can have big impact on the prices of CM. Therefore, the objective of this paper is to explore the possibility of scrap recycling, which can be used to meet some of the demand. To evaluate the amount of scarp that can be used for recycling, we propose a graphical optimization technique (pinch analysis). To show the applicability of pinch analysis and the amount of scrap that can be recycled, two examples are presented.
Contribution/ Originality
This paper contributed in the area of supply chains of critical materials. The methodology used in the paper is Pinch Analysis, which is a graphical optimization method. The methodology used can be useful to determine the potential recycling rates of scrap within supply chain of critical materials.

Abstract
This study was conducted in Simien Mountains National Park, Northwest Ethiopia with the objective of evaluating the patterns of plant community formation and vegetation structure in the afro- alpine vegetation. The data were collected from stratified mountains by using systematic sampling in each stratum from October to November 2015. A total 62 (20 m x20 m) main plots were sampled. In each main plot five (1m x1m) subplots, one at each corner and one at the center, were used to collect data for herbaceous species. In each plot, data on plant species identity, abundance, height and Diameter at Breast Height (DBH) were recorded. Collected specimens were identified at field and also at National Herbarium, Addis Ababa University. Plant community analysis was performed using R version 3.1.3. Sorensen’s similarity coefficient was used to detect dissimilarities among communities. Shannon - Wiener diversity index was computed to describe species diversity of the plant community types. Results showed that a total of 86 plant species representing 34 families and 63 genera were recorded from which90.7 % were herbs, 7% shrubs and 2.3 % trees. Asteraceae is the species richest family whereas Poaceae is the dominant. Three plant community types were recognized from cluster analysis. Species richness, diversity and evenness varied among the plant communities. Analysis of population structure of the dominant species revealed various patterns. Because this afro-alpine area has varied habitat heteroginity, separate plant community regimes need separate planning and implementing (management) measures for sustainability of the vegetation.

Research Article
Author(s): Shi He
Journal: Humanities and Social Sciences Letters

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Drawing on a unique dataset of 530 estimates from 19 studies on foreign direct investment forward productivity spillovers in China, our prime objective is to investigate determinants of forward spillovers from foreign direct investment using Bayesian Model Averaging based Meta-Analysis. Our results suggest that forward spillovers vary across firm attributes, including the ownership structure of foreign firms, the origin of foreign firms, market orientation of foreign firms, the ownership structure of local firms and the technological levels of local firms. Specifically, wholly-owned subsidiaries yields positive technology diffusion to local firms in upstream sectors while joint ventures negative; both foreign firms from Hong Kong, Macao and Taiwan and other economies create negative spillover effects on local buyers; local-orientated foreign firms are likely to generate positive productivity spillovers while export-orientated foreign firms negative; non-state-owned enterprises are likely to benefit more forward technology spillovers from foreign direct investment than state-owned enterprises; middle-tech local firms tend to obtain more forward productivity spillovers than high-tech local firms and low-tech local firms.
Contribution/ Originality
This study contributes in the existing literature on the determinants of forward spillovers from foreign direct investment using Bayesian Model Averaging based Meta-Analysis. The paper's primary contribution is finding that forward spillovers vary across foreign and local firm attributes, such as the ownership structure of foreign firms and the origin of foreign firms.

Abstract
Hibiscus sabdariffa is a species of Hibiscus in the Malvaceae family. Hibiscus sabdariffa is widely consumed as Zobo drink beverage in Nigeria with many health benefits, and it is believed that the brilliant reddish coloration of methanolic extract of this plant’s calyx may have a staining effect on thin blood smear. Hence, this study aims to examine the staining effect of methanolic extract of Hibiscus sabdariffa calyx on thin peripheral blood films in other to obtain more surrogates for hematological stains. Dried calyx of Hibiscus sabdariffa was obtained commercially from Yola. The calyces were pulverized to fine powder and 10g of the powder was soaked in 50ml of absolute methanol for 12hours to obtain methanolic extract. PH of the extract was determined using PH meter. The methanolic extract was used to stain thin peripheral blood smear. Results: Raw methanolic extract of Hibiscus sabdariffa calyx had pH of 1. The extract produces poor staining effect and impacted a pale pinkish-orange appearance on the red blood cells with pseudo large central pallor microscopically. While field stain and Leishman stain produces a dark pink coloration with normal pallor on the red cell. Raw methanolic extract of Hibiscus sabdariffa calyx was acidic and it impacted a poor pale pinkish-orange coloration with pseudo large pallor on red blood cell in thin peripheral blood smear. More research to get a molar equilibrium of acidic and basic substances in this plant’s calyx extract is recommended in other to obtain more cost effective surrogates for good hematological stains.
Contribution/ Originality
This study contributes in the existing literature of the medical importance of Hibiscus sabdariffa calyx with emphasis on the relevance of this extract in medical laboratory practice.

Abstract
A lecture timetable is a tabular list showing the times which a particular lecture is scheduled to hold and the venue for it in each day of the week. Its content includes the course code for each course, the code for the lecture venue and the time for each lecture. A lecture timetable is designed every semester. In this era of technological advancement, virtually every aspect of human endeavour has been automated (the use of machines and computers instead of human to accomplish a task). Now students can pay their school fee, register their courses and even check their results on the internet. This is the drive that gave birth to this research work: the design of an automated lecture timetable for the department of mathematical sciences, KSU Anyigba. The project presents the automated design of lecture timetable. The principle of operation is simple and employs the use of computer technology. A program is written in Visual Basic which produces the output in an error free tabular form displaying the courses/venues for each particular schedule.

Abstract
The isolation of microalgae that can use carbon-rich pollutant from wastewater and accumulate lipids is of great interest in biodiesel production. The heterotrophic cultivation of microalgae could overcome light dependency, and hence increase the yield of microalgae lipid per unit area. After several microbial screening and acclimation procedures, strains of microalgae were proved to be tolerant of wastewater and to grow heterotrophically. One top-performing strain (AE2) was identified through morphological observation as Chlorella sp and was isolated from an open pond of domestic wastewater. This microalgae is able to grow in raw wastewater at 20°C with no illumination and eliminates 100% of its COD (424 mg/L) in 9 days. The biomass produced in wastewater as growth medium comprises 53% of fats of the dry mass and 68% of fats of the dry mass in BG 11 culture medium supplemented with 5 g of glucose/L. The analysis of fatty acid methyl esters FAME composition was 32.5 % of the total biomass. The extracted microalgae oil was converted to good quality biodiesel. This heterotrophic isolated microalgae is a promising strain in terms of wastewater COD removal and cytoplasmic accumulation of high quality and quantity lipids for prospective biodiesel production.
Contribution/ Originality
This study is one of the very few studies which have investigated the isolation of microalgae from the southern climate that can grow efficiently in low carbon sources such as wastewater. The isolated microalgae produced biomass with 53% of fats that are favorable in term quantity and quality for biodiesel conversion.

Abstract
The purpose of this research was to examine the effect of an intervention designed to improve functional movement as determined by Functional Movement Screen ™ (FMS) composite scores, one mile run time, standing isometric hip extension strength, agility T-Test time, and vertical jump in recreational runners (N=12, 7 males and 5 females; Mean Age = 49.08±15.87 yrs.; and mean weekly run volume = 15.96±21.21 miles), while normal running training load was maintained. We employed a two group (Control and Treatment) randomized experimental design. The treatment group (n=6) completed a 6 week intervention using the standard corrective methodology advocated by the FMS organization in combination with their normal run training, while the control group (n=6) continued their normal run training without additional intervention. We found a significant interaction between group and pre/post measure with a large effect sizes demonstrating improvement in the treatment group for the both the 1 mile run time (F = 5.45, p=0.042, Np2= 0.353) and the FMS composite score (F = 10.55, p=0.009, Np2= 0.513). There were no other significant interactions or meaningful effect sizes for any other dependent variable. This study supports the concept that a 6 week standard FMS intervention can result in concurrent improvements in both FMS composite score and 1 mile running performance without a concurrent change in running training load, isometric hip extension strength, vertical jump performance or t-shuttle times, in recreational runners.
Contribution/ Originality
This study contributes in the existing literature by being the first to examine the effect of a corrective intervention for functional movement ability on both FMS score and athletic performance (1-mile run, t-shuttle, vertical jump, hip extension strength) concurrently, while simultaneously controlling for training, in recreational runners.
