    Understanding the Syrian Educational System in a Context of Crisis

    No full text
    Up until the outbreak of conflict in 2011, Syrian young people were among the most educated in the Middle East region, with Syria having achieved near universal primary education enrolment and a high rate of completed secondary education. Due to the years of conflict, many Syrian are currently displaced within their country and across Syria’s borders. In 2015, large numbers made their way across Europe and applied for asylum in Germany, Austria, Sweden, etc. The Syrian crisis raises important education-related questions for the international community as a whole, like the educational background of Syrians currently on the move. This paper gives an overview of the Syrian educational system in order to build an understanding of Syrian education in the broader global context. It aims to provide detailed information that other researchers, policymakers, and practitioners can draw from to inform their own work. The current document was written within the framework of DiPAS (Displaced persons in Austria survey), a survey carried out in and around Vienna to study the socio-demographic characteristics, values and attitudes of asylum seekers arriving in Austria in 2015

    Computing the matrix fractional power with the double exponential formula. ETNA - Electronic Transactions on Numerical Analysis

    No full text
    Two quadrature-based algorithms for computing the matrix fractional power AαA^\alpha are presented in this paper. These algorithms are based on the double exponential (DE) formula, which is well-known for its effectiveness in computing improper integrals as well as in treating nearly arbitrary endpoint singularities. The DE formula transforms a given integral into another integral that is suited for the trapezoidal rule; in this process, the integral interval is transformed into an infinite interval. Therefore, it is necessary to truncate the infinite interval to an appropriate finite interval. In this paper, a truncation method, which is based on a truncation error analysis specialized to the computation of AαA^\alpha, is proposed. Then, two algorithms are presented---one where AαA^\alpha is computed with a fixed number of abscissa points and one with AαA^\alpha computed adaptively. Subsequently, the convergence rate of the DE formula for Hermitian positive definite matrices is analyzed. The convergence rate analysis shows that the DE formula converges faster than Gaussian quadrature when AA is ill-conditioned and α\alpha is a non-unit fraction. Numerical results show that our algorithms achieve the required accuracy and are faster than other algorithms in several situations
