The education domain is one of the business areas with abundant data. Nowadays, most of tertiary educational institutions have dilemmas in identifying probable secondary schools which are considered as feeders for enrollment. The data mining technique of classification has been used in this research to easily identify the target secondary schools for enrollment. With these techniques, higher educational institutions may lessen the marketing cost by filtering which of these secondary schools are considered enrollment contributors. The techniques of ID3, C4.5, BayesNet and Naïve Bayes were used in this research implemented on WEKA 3.6.0 toolkit [1]. Based on the experimental results, C4.5 outperformed ID3, BayesNet and Naïve Bayes in determining the best classification technique to identify the targeted secondary schools qualified for enrollment in tertiary level. The model created can aid in education management’s decision making process in terms of student recruitment.

Aim: The study assessed the effect of urban construction labour supply on agriculture in Nsukka urban, Enugu State, Nigeria.
Study Design: Simple random sampling technique was employed to select respondents for the study.
Methodology: The population of the study included all rural labourers, (male and female) in construction industries in Nsukka urban area. Two major labour assembly points where visited at different parts of the city to collect data. Using simple random sampling technique, 60 labourers were selected randomly from each point given a total sample size of 120 respondents used for the study. Structured interview schedule was employed to collect data. Data was analysised using descriptive statistics.
Results: Majority (79.2%) of the respondents were males. Only 5.8% had no formal education. The mean job experience of the workers was 14 years. Effect on agriculture included loss of family labour (M=2.15), decrease in farm practices (M=2.31), increase in standard of living (M=2.21), loss of farm lands (M=1.92) and reduction on agricultural production (M=2.37). Land area cultivated (< 1 hectare) after joining the construction industry by majority (64.0%) of the respondent had reduced drastically as compared to 1.1-2 hectares cultivated by 85% of the respondents 10 years ago (before migrating to construction industry). The study shows that lack of job security, industrial accidents, delayed payment/low wages, absence of written contract agreement accounted for some of the risk being faced by the construction industry workers. It further encapsulate some benefits enjoyed by the respondents to include earning extra income, payment of children school fees, owning new residential building, improved family nutrition among others. It is therefore recommended that soft loan should be provided to rural dwellers to enable them engage fully in agricultural activities, also, provision of job opportunities as well as social amenities should be provided in the rural areas to curtail migration to urban areas.

Addressing disputes of everyday moral diversity in research and related activities embraces concepts-of-right-and-wrong conduct. To transmit scientific information and theories, besieging gaps abound. Various communication tools have been explored to address exchange of information among researchers in our continual search for systematic creative work, undertaken to increase the stock of knowledge, and the use of this stock of knowledge to devise new applications.

DOI: 10.9734/JSRR/2015/13673

Aim: The present study investigated the effect of operating parameters in modeling the cooling rate of water quenched process.
Methodology: A three factor, three levels Box-Behnken design (BBD) of RSM was applied to determine the effects of three independent variables (Time (A), radial distance (B) and immersion speed (C)) on cooling rate. Response surface analysis method was employed to optimize the parameters in the experiment.
Results: Data analysis shows that A, AB, BC, A2 and B2 are the terms which significantly affected the cooling rate at 95% confidence level. The experimental values were very close to the predicted values and were not statistically different at p<0.05. Optimum cooling rate of 4.75ºC/s was obtained when the time, radial distance and immersion speed were 2.50 minutes, 7.91 mm and 0.22 m/s respectively.
Conclusion: The regression model obtained has provided a basis for selecting optimum process parameters for the cooling rate during water quenching process.

The scavenging behavior of the Bengal Monitor (Varanus bengalensis) was studied at Jahangirnagar University campus, Bangladesh, from February 2010 to July 2010 by following focal sampling method. The behavioral patterns that were observed are scavenging, moving, resting, conflicting, and others (escaping, hiding etc.). The Bengal Monitor spent most of the time in scavenging (43.23%) during their active periods while least time (5.28%) was spent in others (escaping, hiding etc.) behavior. It spent 14.7% in moving, 21.3% resting and 15.5% conflict. During scavenging, the Bengal Monitor mainly fed on chicken feathers, eggshells, fish remains and the waste of vegetable matter. The highest scavenging activity was recorded in April (53.8%) and lowest (27.4%) in February. The scavenging behavior of this species varied in different months and seasons probably due to changing temperature and rainfall.

Power generation is the means of generating power supply into the society. This paper tells how power is being generated from various sources (nuclear, coal, solar, wind, natural gas, water, geothermal, biomass), its major impacts on the society and the possible solution to problems that arise from the process of power generation through the various means considered. The various methods of generating power, no matter how beneficial, still have one or two short-comings which might constitute threat to the peaceful coexistence of living things in the environment. Some of these shortcomings are considered in this paper with possible solutions suggested. Over-aged transmission and distribution lines, unequal phase loads, etc. contribute to electrical power losses in transmission and distribution in Nigeria.
To solve these problems, control measures such as introducing more substations, implementing pre-paid metering systems, using conductors of appropriate sizes and re-aligning the lines are suggested. In order to ensure sustainable power generation, foreign participation based on experience should be encouraged in the Nigerian power sector, the sources of fuel for electricity generating stations should be diversified, etc.

This study was conducted to look at factors that may influence young people in rural communities to choose farming as a career. This paper is based on the experiences of some selected young farmers in the Manya Krobo traditional areas of Ghana. Employing one of the occupational career choice frameworks as a tool for exploring factors that condition occupational career choices, this paper uses narrative of a cross-section of young people from diverse socio-economic backgrounds to show that a complex network of factors motivate rural young people to develop long term occupational careers in farming. This interest often starts from their childhood. It reveals that the reality of being born and bred in a rural community, willingness to identify with community goals, personal aspirations and goals, the belief in personal capabilities, desire to be a recognized local/national farmer and the opportunity to inherit land are some critical factors that influence the youth to embark on farming as a career. In view of this it is suggested that the aspirations of young people in rural farming, social relations with mentors as well as access to agrarian resources, should be considered a priority element of research and development aimed at directing policy on youth and agriculture. It is suggested that future studies should assess the impact of childhood experiences on stimulating the career interests of youth in farming.

The study was carried out to appraise tomato value chain in order to promote the development of tomato production and processing industry in Nigeria. Currently in Nigeria, about 1.8 Million tonnes of fresh tomato are produced per year, but over 50% of these are lost due to poor storage system, poor transportation and lack of processing enterprises. This makes it important to develop strategies for the development of tomato value chain. The method employed in this study includes semi-structured informal interviews with key value chain actors such as producers, intermediate traders, retailers and input suppliers and a critical review of available literature. The study revealed that there are good varieties of tomatoes in Nigeria, but only a few are suitable for industrial processing with regard to quantity and quality. The research also revealed that Nigeria is still not a major exporter of either fresh or processed tomato products despite the high production of fresh tomatoes. This was found to be due to inadequate supply of good quality seeds, inadequate storage facilities, poor disease and pest management, and poor processing facilities. The development of tomato for industrial use is currently gaining momentum, in the area of production of tomato juice, paste, ketchup, puree, and powder. Strategies identified to overcome the challenges include: policy shift to encourage Small and Medium Enterprises (SMEs) as well as Industries along the value chain; improved input supplies; organisation of farmers into cooperatives so as to initiate innovative funding mechanism for them; establishment of clusters for processors; improvement in marketing strategies including guaranteed price for fresh tomato products; adjustment in tariff regime to favour local manufacturers including outright ban on importation of processed tomato products; increased investments in Research and Development (R&D) to produce improved seed varieties and develop technologies for storage and processing; adoption of Good Agricultural Practice (GAP) by farmers and a strong National Commodity Association or Network.
