Research ArticleOpen accessIn the abstractDiversification and Performance of Group-Affiliated Firms during Institutional Transitions: The Case of the Chinese Textile IndustryQiang ZhangProblem statement: Business groups play significant roles and evolve with the changing institutional environments in many emerging Asian economies. A study of how the institutional transition and the resultant ‘institutionally rooted evolution’ of business groups affect the diversification outcomes of affiliated firms will therefore help to deepen our understanding of this unique organizational form. Approach: This study uses the 2001-2005 … …American Journal of Economics and Business Administration, Vol. 3, Issue 2 · 7 Apr 2011 · 7,424 accessesView PDFCite
Research ArticleOpen accessIn the abstractEconomic Growth and Unemployment: An Empirical AnalysisFuad M. KreishanProblem statement: This research investigates the relationship between unemployment and economic growth in Jordan through the implementation of Okun’s law. Approach: Using annual data covering the period 1970-2008, time series techniques are used to test the relation between unemployment and economic growth and to obtain estimates for Okun’s coefficient. Namely, the study used Augmented Dickey-Fuller (ADF) for unit root, cointegration … …Journal of Social Sciences, Vol. 7, Issue 2 · 21 Mar 2011 · 12,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimating the Parameters of the Negative-Lindley Distribution using Broyden-Fletcher-Goldfarb-ShannoNaushad Mamode KhanProblem statement: The Maximum Likelihood Estimation (MLE) technique is the most efficient statistical approach to estimate parameters in a cross-sectional model. Often, MLE gives rise to a set of non-linear systems of equations that need to be solved iteratively using the Newton-Raphson technique. However, in some situations such as in the Negative-Lindley distribution where it involves more than one unknown … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 29 Jan 2011 · 7,378 accessesView PDFCite
Research ArticleOpen accessIn the abstractGrowth Performance and Biomass Accumulation of a Khaya ivorensis Plantation in three Soil Series of UltisolsYetti Heryati, Debora Belawan, Arifin Abdu et al.Abstract: Problem statement: There was no information about the relationship between growth parameters, such as diameter and height and tree component biomass of Khaya ivorensis plantations with different soil types. The objectives of this study were, first, to determine and compare the growth of K. ivorensis in three different (Padang Besar, Durian and Rengam) soil series of Ultisols and, second, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 10,170 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Protease Inhibitors on Metabolic Complications and Lipodystrophy in Human Immunodeficiency Virus-Infected PatientsMohd Khaza, K. Laxmi Prasad, M. EstariProblem statement: Highly Active Antiretroviral Therapy (HAART)-associated metabolic complications include lipoatrophy (loss of Subcutaneous Adipose Tissue (SAT) and insulin resistance. The risk of Diabetes Mellitus (DM) in Human Immunodeficiency Virus (HIV)-infected patients receiving Highly Active Antiretroviral Therapy (HAART) especially protease inhibitors has not been well defined. Approach: We conducted an analysis in the Hospital of Rajeev Gandhi Institute of Medical … …Current Research in Medicine, Vol. 1, Issue 2 · 31 Oct 2010 · 6,934 accessesView PDFCite
Research ArticleOpen accessIn the abstractCyberbullying Education for Parents: A Guide for CliniciansMargaret HannahCyberbullying is a problem that is growing rapidly, current estimates indicate that at least 20-35% of children and adolescents experience cyberbullying. Clinicians need to be equipped with a framework to help parents in the role they play with their children and the cyberworld. This paper will guide professionals as they advise parents in navigating the world of cyberbullying. It is … …Journal of Social Sciences, Vol. 6, Issue 4 · 23 Oct 2010 · 9,620 accessesView PDFCite
Research ArticleOpen accessIn the abstractInterpolating Operators for MultiapproximationEman Samir BhayaProblem statement: There are no simple definitions of operators for best multiapproximation and best one sided multiapproximation which work for any measurable function in Lp for, p>0. This study investigated operators that are good for best multiapproximation and best one sided multiapproximation. Approach: We first introduced some direct results related to the approximation problem of continuous functions by Hermit-Fejer interpolation … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractHealth Impacts Estimation of Mineralogical and Chemical Characterization of Suspended Atmospheric Particles over the East DesertU. Ali Rahoma, Elsayed EmaraProblem statement: The small size fraction of aerosols, measured as PM10 and PM2.5, rather than the larger particles, is considered to be responsible for most of the health effects. Such particles have a relatively long residence time in the atmosphere and can therefore travel over long distances. Hence, a large portion of ambient concentrations of PM10 and in particular of … …American Journal of Infectious Diseases, Vol. 6, Issue 3 · 30 Sep 2010 · 10,772 accessesView PDFCite
Research ArticleOpen accessIn the abstractLeptospirosis in the Tropics: When Prevention Doesn't Easily Sell as a Ton of CureRoger Lee MendozaProblem statement: Human leptospirosis -- the most widespread zoonotic disease -- thrives in tropical and subtropical climates. It is seldom addressed ex ante or prior to an outbreak or expected outbreak by governments of high-risk countries. Whether common, post-exposure treatment with antimicrobial drugs is more cost-efficient than reducing animal reservoir populations was the overarching question that guided this study. A … …American Journal of Economics and Business Administration, Vol. 2, Issue 3 · 30 Sep 2010 · 8,378 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeckle Suppression of Radar Images Using Normalized ConvolutionA. K. Helmy, G. S. El-TaweelProblem statement: Synthetic Aperture Radar (SAR) images are becoming more widely used in remote sensing applications. SAR uses microwave radiation to illuminate the earth's surface. The coherent microwave illumination, however, suffers from fading effects result in generating a multiplicative speckle noise that corrupts SAR images. Approach: Through this study, scheme to reduce speckles was proposed, it was designed to accomplish … …Journal of Computer Science, Vol. 6, Issue 10 · 5 Aug 2010 · 7,259 accessesView PDFCite
