Applied Mathematics 2015年第12期6卷 2096-2103页

作者： R. F. Al-bar Department of Mathematics Faculty of Science Umm Al-Qura University Makkah Saudi Arabia

In this paper, operational matrices of Bernstein polynomials (BPs) are presented for solving the non-linear fractional Logistic differential equation (FLDE). The fractional derivative is described in the Riemann-Liouville sense. The operational matrices for the fractional integration in the Riemann-Liouville sense and the product are used to reduce FLDE to the solution of non-linear system of algebraic equations using Newton iteration method. Numerical results are introduced to satisfy the accuracy and the applicability of the proposed method.

Intimate partner violence(IPV)is simultaneously assumed as a serious crime and a major public health issue,having recurrences as one of its main characteristics and,consequently,re-entries of some alleged offenders in the criminal justice system(CJS).The main goal of this study is to assess if in cases of female victims of IPV,violence decreases after the first entry of the alleged offender in the CJS.A retrospective study was performed based on the analysis of police reports of alleged cases of IPV during a 4-year *** final sample(n=1488)was divided into two groups according to the number of entries in the CJS(single or multiple)followed by a comparative *** suggest that violence decreases after the first entry of alleged offenders in the ***-entries were found in only 15.5%of the cases but they were accountable for 3.3 times more crimes on ***,victims of recidivism presented more injuries and required more medical ***,a small group of alleged offenders seems to be more violent and accountable for most of the IPV crimes registered in the CJS suggesting that regardless of legal sanctions aiming to deter violence,these measures may not be enough for a certain group of *** study sustains the need for a predictive model to quantify the risk of repeated IPV cases within the Portuguese population.

Case study research investigated the launching of an innovative Live Journal, as part of a professional social network, during international conference held in Israel on the subject of teacher training. Research literature notes various publications used to record research and academic materials, but talks less about tools accompanying academic conferences. As far as could be ascertained no online ＂live journal＂ has served the needs of a professional conference. To understand the process and contribution of the Live Journal, qualitative study was chosen, using categorical analysis to interpret materials uploaded by participants on the journal. Additionally, in-depth interviews exposed participants＇ voices and interpretations. The research aimed to identify factors encouraging or hindering the initiative＇s success, patterns of participation, participants＇ characteristics, writing styles and incumbent difficulties and aimed to present a model for optimal operation of the Live Journal. Findings indicate essential components for the journal＇s success include： participants, technology and marketing, noting the importance of each component and their correlation with other components. The journal＇s potential to assist construction of a professional community, and act as an impetus for professional development and familiarity with other professionals in the field indicates the importance of the journal and constitutes the key for success.
