A descriptive study was carried out from 2nd November 2014 to 22nd March 2015. The study aims to assess the psycho-social problems of infertile couples in AL - Hilla city, Babylon Governorate - Iraq. A purposive (non-probability) sample of (50) infertile couple ((50) infertile wives and the other (50) infertile husbands) have been selected from the center of infertility in Babylon Governorate. The questionnaire includes two parts: the first for assessing demographic characteristics of sample, and two domains psychological problems and social problems which include anxiety, depression, self-esteem, and social problems. A questionnaire was adopted and developed according to the Taylor scale for anxiety, the Beck scale for depression, the Rosenberg Self-Esteem Scale (RSES), and a questionnaire of social problems has been constructed.

Effective and ef cient modelling of in nite media is important for the production of accurate and useful solutions for many scienti c and engineering problems invo- ing in nite domains (Bettess 1977, 1980, Chow and Smith 1981, Medina and Taylor 1983, Zhang and Zhao 1987, Zhao et al. 1989, Zhao and Valliappan 1993a, b, c, d, Astley 1996, 1998, Yang et al. 1996, Yang and Huang 2001, Yun et al. 2000, 2007, Wang et al. 2006). Some typical examples involving in nite domains are as follows: (1) earthquake wave propagation within the upper crust of the Earth in the elds of geophysics and seismology, (2) dynamic structure foundation interaction in the elds of geotechnical, civil and dam engineering, and (3) transient pore- uid ow, heat transfer and mass transport within the interior of the Earth in the elds of g- science and geoenvironmental engineering. Although the solid Earth is viewed as a bounded domain at the terrestrial scale, it can be treated as an unbounded domain at the human scale. For instance, in the case of predicting possible property damages caused by an earthquake, only a limited region around the epicentre is of interest because the earthquake wave energy is signi cantly reduced as the distance from the epicentre is increased.

In this work we develop new explicit Discontinuous Galerkin Finite Element schemes, called ADER Discontinuous Galerkin schemes in the following, of arbitrary order of accuracy in space and time to solve linear and nonlinear hyperbolic conservation laws that arise frequently in the description of physical phenomena. Some prominent examples of hyperbolic conservation laws which are treated here are the nonlinear Euler equations of gas dynamics, describing the behavior of compressible gases without viscosity and without heat conduction, or the linearized Euler equations, which are used to model the sound propagation in a medium.The reason for developing very high order schemes is that they permit a good resolution of physical phenomena even on very coarse grids and that they exhibit only very little numerical dissipation, which is important when performing simulations in large domains for long times. Furthermore, grid refinement becomes much more efficient using higher order schemes since numerical errors decrease faster compared to the case when the same grid refinement is applied using a low order scheme. Our method relies essentially on the ADER approach developed originally by Toro et al. in the Finite Volume framework. The strategy consists in solving local generalized Riemann problems on the element interfaces where the initial conditions are piecewise polynomial instead of piecewise constant initial data that are typical of conventional Riemann problems. Toro et al. proposed to solve this kind of initial value problems by making the ansatz of a Taylor series in time at the interface and subsequently replacing time derivatives by space derivatives using repeatedly the governing partial differential equation. We present efficient algorithms for carrying out this procedure for linear and nonlinear hyperbolic systems. Since in the DG framework the numerical solution is allowed to be discontinuous at the element interfaces, the state and the space derivatives at the interface are computed by solving nonlinear and linearized homogeneous conventional Riemann problems, respectively. Finally, one obtains a high order accurate approximation of the numerical flux in time that can be integrated. The resulting scheme is explicit and uses only one single step to integrate the PDE from one time level to the other.

This book examines optimization problems that in practice involve random model parameters. It details the computation of robust optimal solutions, i.e., optimal solutions that are insensitive with respect to random parameter variations, where appropriate deterministic substitute problems are needed. Based on the probability distribution of the random data and using decision theoretical concepts, optimization problems under stochastic uncertainty are converted into appropriate deterministic substitute problems.Due to the probabilities and expectations involved, the book also shows how to apply approximative solution techniques. Several deterministic and stochastic approximation methods are provided: Taylor expansion methods, regression and response surface methods (RSM), probability inequalities, multiple linearization of survival/failure domains, discretization methods, convex approximation/deterministic descent directions/efficient points, stochastic approximation and gradient procedures and differentiation formulas for probabilities and expectations.In the third edition, this book further develops stochastic optimization methods. In particular, it now shows how to apply stochastic optimization methods to the approximate solution of important concrete problems arising in engineering, economics and operations research.

Counseling psychology is a psychological specialty that encompasses research and applied work in several broad domains: counseling process and outcome, supervision and training, career development and counseling, diversity and multiculturalism, and prevention and health. Some unifying themes among counseling psychologists include a focus on assets and strengths, person-environment interactions, educational and career development, brief interactions, and a focus on intact personalities. In the United States of America, the premier scholarly journals of the profession are the Journal of Counseling Psychology and The Counseling Psychologist. In Europe, the scholarly journals of the profession include the European Journal of Counselling Psychology (under the auspices of the European Association of Counselling Psychology) and the Counselling Psychology Review (under the auspices of the British Psychological Society). Counselling Psychology Quarterly is an international interdisciplinary publication of Routledge (part of the Taylor & Francis Group).

'Kate Hefferon and Ilona Boniwell have done an excellent job on this introduction to Positive Psychology! I encourage educators, students and everyone else interested in an updated, well-written and culturally balanced approach to the scientific study of human flourishing, to read this highly accessible, yet rigorously crafted text; and to get it under your skin by ways of carefully chosen tests and exercises.' Hans Henrik Knoop, Aarhus University, Denmark and President, European Network for Positive Psychology 'This accessible, yet comprehensive, book provides an excellent new resource in the area of positive psychology. Students, researchers and practitioners alike will benefit from the skilful and lively integration of theory, research and application. The authors are prominent members of the international positive psychology movement and as such are able to deliver a confident, practical and overarching assessment of the area, integrated into psychology more widely.' Angela Clow, University of Westminster, UK 'This is an exceptional book that synthesizes more than a decade of positive psychology research into chapters that are engaging, accessible, and educational. Hefferon and Boniwell demonstrate a mastery of the literature through the ways in which they have marshaled the evidence from research and practice into this invaluable resource. This book will become an essential reference guide for researchers, educators and practitioners of positive psychology around the world.' Professor Alex Linley, Founding Director, Capp 'This book is a valuable resource for students looking for an introduction to Positive Psychology, but also wanting to get a comprehensive and updated overview of this innovative approach to the study of human behaviour and experience. It provides a broad coverage of the most relevant theories and constructs developed within Positive Psychology, and of their relevance for intervention and application in the most diverse life domains. Hefferon and Boniwell use a rigorous though accessible and friendly style of presentation. By means of effective learning supports, they stimulate readers' active engagement in critical reflections on each topic. The authors address the several issues and open questions which still characterize Positive Psychology as a relatively recent domain through a balanced and objective approach.' Antonella Delle Fave, University of Milano, Italy 'Kate Hefferon and Ilona Boniwell have produced the first textbook which has set out purposefully to support students and teachers in higher education in the exciting new area of positive psychology. The authors have experience of teaching the lectures described in each chapter and the book is written in a way that students will find engaging and fun. Each chapter has clear learning objectives, mock essay questions, measurement tools, summaries and a guide to further resources. The content has been well researched and the early chapters cover the main concepts of positive psychology such as emotions, happiness, wellbeing, optimism, and resilience. The later chapters are more novel and cover interventions and applications all with a critical eye. Of particular note is the chapter on the body in positive psychology - a topic which is frequently omitted from the 'thoughts and feelings' approach of other texts in this area. I would strongly recommend this book to all students and teachers of psychology.' Nanette Mutrie, Professor of Exercise and Sport Psychology, Strathclyde University, UK 'The text is well written, clear and engaging making it an invaluable resource to those seeking an introductory text or for a more comprehensive coverage of the applications of positive psychology. I would highly recommend this text to all students and higher education lecturers studying or teaching the psychology of happiness and wellbeing.' Charlotte Taylor, Research Assistant, University of Worcester, UK 'The authors utilise their own multidisciplinary experiences in the field of psychology in an endeavour to provide an effective textbook to accompany university level courses on Positive Psychology, an endeavour which appears to have been accomplished with a high degree of success.' Steven Southworth, Postgraduate Psychology student, University
