A method for automatic generation of most of the data required by the Agricultural Non point Source erosion model is developed from three sources:(1) file with contour lines from the topographic maps(TM), (2) soil mapping units from the soil surveys, and (3)land cover from land sat TM image classification.展开更多

In spite of various common causes for the Arab uprisings, the paper spotlights the ＂Youth role＂ and its regarded issues of ＂Youth Bulge＂, ＂Education＂ and ＂Unemployment＂ with a glimpse to the overturned regimes of ＂Tunisia, Egypt, Libya, and Yemen＂. According to published statistics these countries are among the countries with the highest rate of youth as working age population in MENA. Therefore, the paper is to present the importance and impact of youth as a social parameter in challenging political structure of the countries in the MENA and leading to topple their political systems. Thus, the paper reasons the MENA political upheavals, in general, and the mentioned countries＇ uprisings, in particular, can not be well understood disregarding to natural tensions between economic, population structures, and political demographic challenges. This is to be done drawing on data from different international institutions. The intervened variables such as ＂ethnicity, race, religion and sexuality＂ and international parameters have not been considered.展开更多

In this paper, the authors formally define the categorical data clustering problem as an optimization problem from the viewpoint of cluster ensemble, and apply cluster ensemble approach for clustering categorical data. Experimental results on real datasets show that better clustering accuracy can be obtained by comparing with existing categorical data clustering algorithms.展开更多

This paper examines the Nigerian informal sector and the extent of conformity with proper human resource practices. This paper adopts survey approach in analyzing data to test whether or not SMEs can conform to global HRM practices by analyzing some variables. Graphs and simple statistics were used to test the probability of conformity of informal sector activities with HRM practices in Nigeria. This paper also relied on secondary data from Bureau of Statistics and other government agencies. Past literatures were also examined. It was discovered that due to low capital outlay and inability to access funds from financial institutions, global human resource practices like proper recruitment, training, career development are being ignored.展开更多
