Research ArticleOpen accessIn the abstractComplexity in Human Perception of Brightness: A Historical Review on the Evolution of the Philosophy of Visual PerceptionKuntal Ghosh, Kamales BhaumikProblem statement: The “eye-brain” complex, which contributes maximally to visual perception, is no doubt a very interesting object for complexity study. In this review we shall try to present some of its aspects in perceiving brightness. It is a well-known fact that the perceived brightness of any surface depends on the brightness of the surfaces that surround it, a phenomenon … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 8,680 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe So-Called Moderate Justices on the Rehnquist Court: The Role of Stare Decisis in Salient and Closely-Divided CasesPaul Douglas FooteProblem statement: A major question that has puzzled political scientists is what factors influence the decisions of US Supreme Court justices. Despite 20th Century statutory reforms that have led to a fundamental weakening of institutional cohesion on the Supreme Court, the norm of stare decisis continues to serve as a constraint to moderate decision-makers under certain external conditions. Evaluate voting … …Journal of Social Sciences, Vol. 6, Issue 2 · 30 Jun 2010 · 8,147 accessesView PDFCite
Research ArticleOpen accessIn the abstractOsteoporosis Induction in Animal ModelKamran Kaveh, Rashid Ibrahim, Mohd Zuki AbuBakar, Tengku Azmi IbrahimProblem statement: Osteoporosis; the major health problem is an imperative disease requires a significant attention to discover different aspects of this threatening abnormality. There are some problems in osteoporotic human population to conduct researches such as lack of a homogenous sample size or ethical problems. So, there was a need to have protocol in animal model to let the scientists … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 9,305 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoil Compaction and Oil Palm (Elaeis guineensis) Yield in a Clay Textured SoilZuraidah Yahya, Aminuddin Husin, Jamal Talib et al.Problem Statement: The impacts of soil compaction on crop yields have been studied extensively by soil scientists due to declining soil productivity associated with mechanisation. However, a relationship between machine-induced soil compaction and oil palm (Elaeis guineensis) yield is unclear. Therefore, the objectives of this study were to determine the effects of mechanization on soil physical properties and the influence … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 10,280 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization Techniques for Variable Selection in Binary Logistic Regression Model Applied to Desire for Children DataS. K. Sarkar, Habshah MidiProblem statement: The population problem is the biggest problem in the world. In the global and regional context, Bangladesh population has drawn considerable attention of the social scientists, policy makers and international organizations. Bangladesh is now world’s 10th populous country having about 140 million people.
