Research ArticleOpen accessIn the abstractDo Personal Strengths and Weaknesses Impact Subjective Well-being of Elderly?Nurhayati Mohamad, Khadijah Alavi, Mohd Suhaimi Mohamad et al.Everyone gets affected by the challenges of aging, but personal strengths and weaknesses of elderly people influence their well-being the most. The current study is designed to measure the impact of personal strengths (intergenerational social support and self-esteem) and weakness (loneliness) on Subjective Well-Being (SWB) of Malaysian institutionalized elders. A cross-sectional survey design is employed to arrive at the random … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 15 Jan 2017 · 7,708 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Analysis on the Performance of the Convoluted Exponential Distribution and the Exponential Distribution in Terms of FlexibilityEnahoro Alfred Owoloko, Pelumi Emmanuel Oguntunde, Adebowale Olusola AdejumoIn this article, the convoluted exponential distribution which was derived as the sum of two independent exponentially distributed random variables was compared with the exponential distribution in terms of flexibility when applied to four real data sets. The idea is to verify if the convoluted exponential distribution would perform better than the exponential distribution in modeling real life situations. Some … …Journal of Mathematics and Statistics, Vol. 12, Issue 1 · 15 Apr 2016 · 6,983 accessesView PDFCite
Research ArticleOpen accessIn the abstractASYMPTOTIC BEHAVIOR OF FINITE-TIME RUIN PROBABILITY IN A BY-CLAIM RISK MODEL WITH CONSTANT INTEREST RATELei WangThis study investigates the ruin probability of a renewal risk model with constant interest rate and by-claim parts. We assume that the claim size and the inter-arrival time satisfy a certain dependent structure with some additional assumptions on their distribution functions. In particular, we study the asymptotic behavior of P(R*δ´ (t, x) >x), which holds uniformly in a finite interval. … …Journal of Mathematics and Statistics, Vol. 10, Issue 3 · 5 Aug 2014 · 6,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractAN APPROACH FOR TEXT SUMMARIZATION USING DEEP LEARNING ALGORITHMG. PadmaPriya, K. DuraiswamyNow days many research is going on for text summarization. Because of increasing information in the internet, these kind of research are gaining more and more attention among the researchers. Extractive text summarization generates a brief summary by extracting proper set of sentences from a document or multiple documents by deep learning. The whole concept is to reduce or minimize … …Journal of Computer Science, Vol. 10, Issue 1 · 7 Nov 2013 · 7,803 accessesView PDFCite
Research ArticleOpen accessIn the abstractMOMENTS OF NONIDENTICAL ORDER STATISTICS FROM BURR XII DISTRIBUTION WITH GAMMA AND NORMAL OUTLIERSZ.A. Al-Saiary, A. A. JamjoomThere are some distributions with no simple closed form for distribution functions such as the Normal and Gamma distributions. This will be the problem if we want to find moments of nonidentical order statistics in the presence of Gamma and Normal outliers observations. We used the idea of approximating Normal and Gamma distributions with Burr type XII distribution. We get … …Journal of Mathematics and Statistics, Vol. 9, Issue 1 · 12 Apr 2013 · 7,040 accessesView PDFCite
Research ArticleOpen accessIn the abstractOrganizational Factors and Innovativeness of Housing DevelopersAhmed Mohammed Kamaruddeen, Nor’ Aini Yusof, Ilias Said, Abd Hamid Kadir PakirIn examining the influence of a firm’s structure and culture on innovativeness among housing developers in Malaysia, we draw a theoretical perspective to develop hypotheses, that propose the structure and culture of the firm as organizational factors which influence innovativeness. We, therefore, examine the direct relationship between independent variables (firm structure and culture) and the dependent variable (firm innovativeness). While … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 12 Dec 2012 · 7,693 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Attitude Toward Watershed Management Operation on Level of People ParticipationB. M. Golrang, F. S. Lai, M. Rostami et al.Recent studies in many countries had display the influence of many factors including: Satisfaction, Knowledge, Demographic and Attitudinal variables in level of people participation. The main question here is, whether these factors would also be effective on people participation in Iran? The purpose of this research was to investigate communication factors influencing attitudes of farmers’ application of Watershed Management Operations … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 19 Nov 2012 · 8,053 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinding the Envelope and Efficient Frontier of Financial AssetsFarida Kachapova, Ilias KachapovProblem statement: One of the problems considered in financial mathematics is finding portfolios of given financial assets that minimize risk for targeted returns. The set of such portfolios is called the envelope of the assets. Traditionally this problem is solved as a calculus minimization problem involving partial derivatives and Lagrange multipliers. Approach: In this study we describe an invariant geometric … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 16 Jul 2012 · 9,279 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of the Maize (Zea mays)-Mucuna (Mucuna deeringianum Bort) AgroecosystemCarlos Ernesto Aguilar-Jimenez, Alfredo Tolon-Becerra, Xavier Lastra-BravoProblem statement: In Selva de Chiapas, Mexico, the traditional farming technique of slash-fell-burn used on hillside fields has caused severe soil deterioration. Consequently, indigenous farmers reacted by developing several agroecological practices that improve the physical, chemical and biological fertility of the soils. Standing out among these techniques is the use of Mucuna (Mucuna deeringianum Bort.) in rotation with maize (Zea … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 2 · 30 Mar 2012 · 7,987 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuality of Life of the Elderly ResidentsFereshteh Farzianpour, Shayan Hosseini, Maryam Rostami et al.Problem statement: A preliminary investigation of the Orem self-care training effects on the Quality Of Life (QOL) of the health care centers’ elderly residents in the city of Masjed Solaiman, Iran. Approach: The Orem self-care training was administered to 349 elderly free of chronic disorders (aged 65 and older). The eligible participants were selected from 11 health centers. The training … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 5 Nov 2011 · 8,525 accessesView PDFCite
