Abstract
Weight (resistance) training can increase strength and muscle mass. A personalized training protocol (i.e., with optimum frequency and number of sets) was followed for 4 months by a 40-year old male with 20 years of weight training experience. The body was split in three parts and was trained every 5-6 days. The strength increase was between 7% (back) and 17% (legs), while the free-fat mass increase was 0.4 kg (0.5%), which was lost after the 4-month period. It was shown that reduced sleep duration for one night did not affect the strength performance. However, with 2 days of reduced sleep, there were indications of worse performance. The results confirm the importance of personalized weight training programs and good sleep habits for strength improvements.
Contribution/ Originality
This study documents that a personalized weight (resistance) training programs can result in strength increases even for advanced trainees. This study contributes in the existing literature showing that one-night sleep restriction only slightly affects strength performance, but two nights of reduced sleep duration have a negative effect.

Journal: The International Journal of Biotechnology

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The aim of this study was to isolate and screen citric acid producing yeasts using low cost substrates. Thirty three yeast isolates were obtained from pineapple, plantain and sugar cane waste and identified as; Saccharomyces cerevisiae, Schizosaccharomyces pombe, Candida tropicalis, Pichia guilliiermondii, Debaromyces sp., Candida parapsilosis, Candida rugosa, and Candida krusei. Candida tropicalis had zone of clearance of 49±2.1 mm in diameter, Pichia guilliermondii had 40±1.2mm. Saccharomyces cerevisiae produced citric acid with glucose with 105.0 mg/l. C. tropicalis yielded 132.2 mg/l with sodium nitrate. S. cerevisiae and C. tropicalis produced citric acid at pH 6 with 23.70mg/l and 23.80mg/l. P. gulliermondii at pH 4 produced 23.00mg/l. The temperature of 30°C favoured S. cerevisiae and C. tropicalis yielding 40.80mg/l and 39.80 mg/l. After extraction, the yield of the citric acid was 4.231g, 3g of which was recrystallized to yield 2.16g of pure citric acid resulting into 72% recovery. The result indicated that pineapple wastes, plantain wastes and sugarcane cane are potential sources of yeasts that can be used for the production of citric acid.
Contribution/ Originality
This study contributes in the existing literature by providing basic information for other researchers regarding the isolation and the screening of yeasts for the production of citric acid using low cost substrates, as well as to study the effect of various fermentation parameters on citric acid production.

Abstract
Gender inequities in labour market opportunities is a particular concern since earnings from labour supplies are the most important source of income for the poor in the rural economies of developing countries. This study examined gender differentials in labour market participation of rural households in non-farm activities in Oyo state, Nigeria. A multistage random sampling technique was employed in selecting 120 rural households. Descriptive Statistics, Double- Hurdle regression model and Multinomial Logit regression models were the analytical tools employed. The mean farm size was relatively small as more than three-quarters of both male and female headed households respectively cultivated less than 1 hectare. Regression results indicated that male and female headed households participated and allocated more time to non-farm activities as their age and household size increased while farm size and remittances had negative effects. The decision on whether a household would hire or supply labour was largely influenced by the age of the household head, farm size, farming experience, household size and being a member of a cooperative group. However, female headed households’ participation was constrained mainly by inaccessibility to town as a result of the long distance between the homestead and the nearest town. The study recommends the establishment of small and medium enterprises in the rural areas to encourage the participation of both male and female headed households in non-farm income generating activities to cushion declining farm incomes.
Contribution/ Originality
This study contributes in the existing literature by complementing current research on labour market participation in Oyo State, Nigeria, a few of which have examined gender differences in non-farm activities by rural households.

Abstract
The study examined the effect of community financing institutions on cassava farmers’ income in Oyo State. The objectives were to examine the socio-economic characteristics of the respondents in the study area, identify governmental & non-governmental community financing institutions in the study area, and examine the effect of the financial institution programme on respondents’ income and to identify the factors affecting the accessibility of credit facilities among small holder farmers in Oyo State. A Multi-stage sampling technique was used for this study. In the first stage, a purposive sampling was used to select Lagelu, Akinyele and Ido Local Government Areas in Ibadan. Random sampling was used to select three communities from each of the three Local Government Areas and from each community, 10 respondents were selected randomly to give a total of 90 respondents of cassava farmers and processors. The analysis of the socio-economic characteristics revealed that majority of respondents that were involved in the cassava production and processing activities in the study area were males, the ages ranged between 17- about 65years and majority (38.9%) were between the ages 49-56years with the mean age of 49 years. Most (96.7%) were married with a high household size of between 6-10 numbers. The level of education of respondents revealed that majority (43.3%) had one form of education or the other which could enhance performance in production and processing activities. The primary occupation of respondents reveals that all of them were farmers, some are artisans and their monthly allowance ranged between less than ?20,000.00 and ?75,000.00 as most of them earn less than ?30,000.00. Chi square showed that there is a significant association between rural financing institution and cassava farmers’ income (?²=0.014, p=6). Also 57.8% of the respondents affirmed that the benefits received from the financial institution has a high effects on their standard of living which is affirmed by 43.3% of the respondents who agreed that their monthly income has increased as a result of the accessibility to fund. From the result, 53.3% of the respondents claimed that the high interest rate charged by the institution was the major challenge and 47.8% of the respondents affirmed that the Interest rate should be affordable as this will enhance accessibility of credits.
Contribution/ Originality
This original study focused on the effects of community financing institution on cassava farmers’ income. It revealed the significant relationship between rural financing and cassava farmers’ income and also the major constraint of high interest rate facing the farmers in the study area.

Abstract
The study was conducted to identify determinants of losses during pre-harvest and postharvest activities of fruits and their extent at producer`s level in Northwestern Ethiopia where tomato, papaya, avocado, banana and mango were used as fruit samples. Questionnaires were used to collect data from 180 randomly selected respondents of six districts (FinoteSelam, BurieZuria, Bahir Dar, Bahir Dar Zuria, Dangla and Farta). Descriptive statistics and multiple regressions analysis were used to identify determinant factors. The results of the findings revealed that the total fruit loss was estimated to be 44.8% where about 20.7% of the fruits were lost due to improper activities in the pre-harvest stages while about 24.1% loss was due to improper activities during post-harvest stages. The shares of pre-harvest and postharvest losses to the total fruit loss were about 46.2% and 53.8%, respectively. Income sources, use of pesticide, and use of compost or manure during production were the determinant factors that influenced fruit losses during pre-harvest while experience and educational levels of producers in fruit production and shortage of labor were the determinant factors of fruit losses during harvesting. Moreover, chemical treatments of fruits before storage and educational levels of the producers were the determinants that influenced fruit losses in producer`s storage while experiences of the fruit producers, distance to market and educational levels were the significant factors of fruit losses during marketing. Further researches and trainings of producers about use of pre- and post-harvest technologies that minimize losses at the value chain of fruits are vital.
Contribution/ Originality
This survey is one the few researches that has estimated fruit loss and identified the major factors responsible for loss. The research paper contribution is finding that about 44.8 percent fruit is lost and use of pre- and post-harvest technologies as well as educating producers about fruit loss is vital.

Journal: Journal of Empirical Studies

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Using signal extraction, this study identifies leading indicators of financial crisis over the period 1980-2015 in developing and advanced economies. The study evaluates vulnerability in the external, public and financial sector in developing countries. The results postulate that the level of imports is the principal leading indicator for detecting a forthcoming crisis in developing nation’s external sector. In the public sector, the best indicators for predicting a crisis in South Africa are in the order: maturity of debt; external debt; debt-GDP ratio; interest rate payments; short-term debt and government expenditure. In Namibia, the best indicator for predicting crisis is total expenditure and interest rate payments. Comparatively, Russia’s crises are better predicted by the following variables: debt ratio; interest rate payments; short-term debt; expenditure and external debt. The two best indicators were debt ratio and interest rate payments. In the financial sector, the common risk indicator among developing economies is the lending rate. The external balance sheet assessment shows that in developed countries, predictors of a financial emanate from portfolio investments and direct investments. For the UK, the best indicators of a looming financial crisis are: direct investment liabilities; portfolio debt liabilities and direct investment debt instruments.
Contribution/ Originality
This study is one of the first contributions in early warning systems that assesses vulnerability in multiple sectors of an economy which are external, public and financial sectors. To the best of the author’s knowledge, this study is also the first to determine external balance sheet assessment in developed nations.

Triple Hurdle Model with Zero Expenditures

Research Article
Author(s): Yeong Nain Chi
Journal: Quarterly Journal of Econometrics Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The Tobit model is a one-step decision method, implying that the decision to participate and the decision of how much to spend are influenced by the same variables and in the same manner. The double hurdle model is a two-step decision process; consumers first decide whether or not to participate, and then a second decision is made on how much to spend. The triple hurdle model has three separate stochastic decision choices for the first stage of awareness, the second stage of participation, and a final stage of consumption decision. This study provides a guidance in the choice of an appropriate model, which all observations can be used in the estimation for awareness and participation decisions, but only positive observations that pass awareness, participation and consumption decisions simultaneously can be used in the estimation based on a censored and truncated sample, allowing for richer interpretation of consumer choice behavior.
Contribution/ Originality
This study provides guidance in the choice of an appropriate model in the Tobit model, double hurdle model, and triple hurdle model in empirical expenditure analyses, which contain a high proportion of zero expenditure in the microdata, based on the Likelihood Ratio test.

Journal: Review of Computer Engineering Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
In this paper, the propagation loss for 1800 MHz cellular network in a crowded market is studied and characterized using the Comit´e International des Radio-Communication, (CCIR) propagation loss model. Empirical measurement of the received signal strength in the market was conducted using CellMapper android app installed on Samsung Galaxy S4 phone. The CCIR model was configured with three different percentages of covered areas (PB). The model was optimized using the root means square error (RMSE) method and also by tuning the PB value. The un-tuned CCIR model gave an RMSE value of 9.23 dB which is above the acceptable upper limit of 6 dB for propagation loss prediction models. On the other hand, the PB-tuned CCIR model gave the best prediction result with an RMSE value of 2.177 dB and prediction accuracy of 98.11 % which is better than the performance of all the RMSE-tuned CCIR models. The results showed that apart from using an RMSE value to tune the CCIR propagation loss model, adjustment of some other key parameters of the model can as well provide a better prediction performance. However, the choice of the parameter to be tuned depends on the specific nature of the case study area.
Contribution/ Originality
The paper's primary contribution is the development of an alternative approach for optimizing the CCIR model by adjusting the percentage of covered area rather than using the root mean square error (RMSE). The paper demonstrated that the proposed method can give better propagation prediction performance than the RMSE-based optimization approach.

Abstract
In this paper the impact of adjusting the optimal tilt angle of solar photovoltaic (PV) modules on monthly bases was studied and compared to that of the annually-fixed optimal tilt angle. PVSyst software was used to determine the optimal tilt angle for each month for a given case study site in Imo state in Nigeria. Mathematical models for computing the required PV array power to meet the daily energy demand of 100 kWh were presented. Addition parameters considered in the study were the PV array number of modules as well as PV array area and cost. For the case study 100 kWh daily energy demand, the selected PV module had a peak power rating of 100W, with a unit cost of N 18,000 and with dimensions that gave an area of 0.65945m^2. The results showed that there is about 4 % (annual average) reduction in the required PV array power when the monthly adjustment of the optimal tilt angle is used. December had the highest percentage reduction in the required PV array power. The reduction in the PV array power resulted in the corresponding reduction in the number of PV modules needed to provide the required power, as well as a reduction in PV array area and cost.
Contribution/ Originality
This study is one of the very few studies which have investigated the impact of the optimal tilt angle on the solar photovoltaic array size and cost for the solar power system in Imo state, Nigeria.

Abstract
In recent times, there are increases in the incidence of child labor in Lagos State. Many children worked in informal sectors of the economy such as market, construction sites, beer parlors, and motor parks. Many were on the streets hawking and begging for alms. Economic doldrums, lack of parental care and forced migration were linked with the rampant in child labor in Lagos State. The problem is the Child’s Rights Act promulgated by the Lagos State government has become so ineffective. This study therefore, sets to examine the reasons for surge in child labor in recent times in Lagos State. It investigates government’s efforts in the protection of children. The study also examines parental roles in providing and nurturing children. Anomie and Social Structure Theory was used in this study to explain the reason why many children engaged in labor. This study was conducted in two areas with highest cases of child labor in Lagos State, namely: Oshodi, and Lagos Island. Qualitative method of data collection was used in this study. In-depth interviews were conducted among one hundred and ninety-eight child laborers, and fourteen welfare officers. This study found that many child laborers were abandoned by their parents, guardians and relatives. Many were truants, victims of breaking home, poverty, polygamy and forced migration. This study concluded that government should provide welfare services for children who are between Age 0 and 18. The number of children per family should also be limited to 3.

Abstract
Using non-linear models to forecast volatility for three equity index samples, this study examines weekly returns of three indices; Dow Jones Industrial index, FTSE 100 index, and Nikkei 225 index. The sample covers a twenty year sample period. The study employs an in sample and out of sample volatility forecast using standard symmetric loss functions in order to identify an appropriate model that best forecast volatility. Using the mean error (ME), root mean square error (RMSE), mean absolute error (MAE), and mean absolute percentage error (MAPE), the study finds the EGARCH model to outperform the ARCH, and GARCH model in forecasting volatility.
Contribution/ Originality
This is among the first studies that found EGARCH model to outperform the ARCH, and GARCH model in forecasting volatility using a combination of Japan, UK and US data.
