The Relationship of Certain Selected Variables to First Grade Achievement

Educators have long been aware of the need for adequate predictors of school achievement for first grade pupils. Moreover, there is growing interest in the screening of school beginners, both as a means of determining their readiness for learning and as a way of identifying early those children with potential difficulties so that they can be given required attention at a time when it will be most beneficial

Introduction

Değirmencioğlu, Serdar M. (Dogus Author)Debt and personal indebtedness have become a global problem as consumption-driven economies have spread across the world. These days, outstanding consumer debt is a normal feature of many economies and for a large number of people, the source of great mental distress. However, an understanding of personal debt requires an understanding of the complex social systems that produce poverty. This book frames credit use as a social phenomenon, and explores the dynamic interplays between consumers who need credit and credit granting institutions. By drawing upon a range of international perspectives, this book sheds much needed light on the social and psychological factors that contribute to the growth of personal debt and its associated impact on wellbeing. In so doing, the book contributes to an understanding of why more and more people are in debt, why it is causing so much harm to so many people and exactly who is benefiting from what has become the world's number one growth industry

The Electromagnetic Self-Energy Contribution to M_p - M_n and the Isovector Nucleon Magnetic Polarizability

We update the determination of the isovector nucleon electromagnetic self-energy, valid to leading order in QED. A technical oversight in the literature concerning the elastic contribution to Cottingham's formula is corrected and modern knowledge of the structure functions is used to precisely determine the inelastic contribution. We find \delta M_{p-n}^\gamma = 1.30(03)(47) MeV. The largest uncertainty arises from a subtraction term required in the dispersive analysis, which can be related to the isovector magnetic polarizability. With plausible model assumptions, we can combine our calculation with additional input from lattice QCD to constrain this polarizability as: \beta_{p-n} = -0.87(85) x 10^{-4} fm^3.Comment: 5 pages, version accepted for publication in PR
