This volume contains lectures presented at the 14th Annual Hampton University Graduate Studies at the Continuous Electron Beam Accelerator Facility (HUGS at CEBAF), that took place at Jefferson Lab and Hampton University from June 1st to 18th, 1999. The programme was focused on the structure of hadrons from the low to the high energy regimes, including a balance of theory and experiment, and emphasized topics in electron scattering on the nucleon and nuclei.

Written by leading experts in the field, this book provides an authoritative overview on electromagnetic interactions. It describes the main features of the experimental data and the theoretical ideas used in their interpretation, and is an essential reference for graduate students and researchers in particle physics and electromagnetic interactions.

One of the activities of the Ettore Majorana Centre for ,Scientific Culture is the international advanced study courses on scientific topics which are of particular relevance today. The Centre is located in Erice, a mountain town in the province of Trapani in Sicily. At present over seventy Schools of the Centre are active, holding annual or biennial courses, so that about forty courses are organized each year. To date some twenty thou sand participants have attended the courses of the various Schools of the Centre. The International Physics Workshop Series has been established to make the contents of the Workshops o'f great topical interest available to those who were unable to attend them. The courses are conducted on an advanced, post-doctoral level. This volume - the proceedings of the session on "Quarks and Hadronic Structure" - is the first of the Series. In September 1975, thirty-three physicists from twenty-one laboratories in nine countries met in Erice to attend the Workshop. The countries represented were: Austria, France, Germany, India, Italy, Poland, Switzerland, the United Kingdom, and the United States of America. The purpose of this Workshop was to bring to gether a group of theorists working on various aspects of the quark structure of hadrons to discuss and critically evaluate the present situation. Professor Morpurgo was given the direction of the Workshop. I would like to take this opportunity to thank him most warmly for having accepted this responsibility and for the success of the Work shop.

This book contains the proceedings of the third international workshop on From Parity Violation to Hadronic Structure and More. The many applications of parity violation are way beyond the scope of what Lee and Yang could have imagined fifty years after their proposal. For the physics topics discussed during this workshop, the application of parity violation has become a standard work horse allowing for the extraction of many physics topics in different experiments.

Almost 50 years after the proposal of Lee and Young in 1956 to test the hypothesis of parity violation in weak interactions and the subsequent experimental verification of parity violation by C. S. Wu, parity violation has today become a useful property of weak interactions. This is due to the fact that the focus nowadays has changed: parity violation in weak interactions is no more a topic of investigation but is used as a tool in many different fields ranging from nuclear physics to the search for the hidden extra dimensions requested by string theory. For our first workshop which took place June 5-8, 2002, at the Institut fiir Ke- physik of the Johannes Gutenberg-Universitat Mainz, we concentrated on the in vestigation of the strangeness contribution in the nucleon. This book contains the refereed and selected papers of the second workshop "From Parity Violation to Hadron Structure and more (Part II)", which took place June 8-11, in the Labo- toire de Physique Subatomique et de Cosmologie, in Grenoble. These papers appear in EPJAdirect, the electronic-only part of EPJA, and they are accessible without restrictions. They will also appear in printed form and can be ordered through Springer. The excellent presentations show the dramatic and steady progress in the accuracy of measured parity violating asymmetries over the last few years.
