|
A CASE OF PLAGIARISM (Case No. 28122012)
Assistant Professor Dr. A.V. Dorugade pointed out a plagiarism in a paper published in Asian Journal of Mathematics and Statistics Volume 4 Number 2, 90-97, 2011. On the receipt of Assistant Professor Dr. A.V. Dorugade’s letter, the case forwarded to the Ethics Committee of the Science Alert. As per the report of the Ethics Committee, article entitled "An Efficient Estimation Procedure For Determining Ridge Regression Parameter" authored by Moawad El-Fallah Abd El-Salam from Department of Statistics and Mathematics and Insurance, Faculty of Commerce, Zagazig University, Zagazig, Egypt published in Asian Journal of Mathematics and Statistics Volume 4 Number 2, 90-97, 2011, contains substantial sections of text that have been taken verbatim from earlier publication without clear and unambiguous attribution. Science Alert considers misappropriation of intellectual property and duplication of text from other authors or publications without clear and unambiguous attribution totally unacceptable. Plagiarism is a violation of copyright and a serious breach of scientific ethics. The Editors and Publisher have agreed to officially retract this article. Science Alert is highly thankful to Assistant Professor Dr. A.V. Dorugade, for pointing out this plagiarism. Detail of article from which text has been copied by Moawad El-Fallah Abd El-Salam: A. V. Dorugade and D. N. Kashid, 2010. Alternative Method for Choosing Ridge Parameter for Regression, 4: 447 - 456, 2010.
