This is a new release of the original 1924 edition.

The electron was first discovered in 1898 by Sir John Joseph Thomson and has since been the subject of detailed study by nearly every scientific discipline. At nearly the same time Heinrich Rudolf Hertz conducted a series of experiments using cathode tubes, high potentials and ultraviolet light. When applying a large potential to a cathode he found that an arching event across the metal plates would occur. In addition, when shining an ultraviolet light on the metal he found that less potential was required to induce the spark. This result, taken together with other electrical phenomena brought about by the shining of light upon metal and was eventually termed the photoelectric effect. The work of Thomson and Hertz represent the beginning of electron emission studies and a body of ideas that pervade nearly all aspects of physics. In particular these ideas tell us a great deal about the nature of physical interactions within solids. In this thesis we will focus on the emission of electrons induced by an incident electron source over a range of energies, in which one can observe changes in emitted electron flux and energy distribution. In particular, when energetic particles impinge on a solid they can impart their energy, exciting electrons within the material. If this energy is sufficient to overcome surface energy barriers such as the work function, electron affinity or surface charge potential, electrons can escape from the material. The extent of electron emission from the material can be quantified as the ratio of incident particle flux to emitted particle flux, and is termed the electron yield.

Ever wondered what transparency can look like in your life? Are you transparent? What does transparency really mean? In a world full of hurt, deception, betrayal, and evil, how are we to risk opening up to others? Who can we trust? How can we begin to share our lives when we do not fully understand the expectations we have concerning ourselves, God, and others? At times, real transparency can seem unattainable. If we are to show others true love, as God intended, we must risk walking the sometimes scary line of transparency. This book will challenge readers to become transparent in every area of their lives so that love can be shown. This transparency will open the door to better growth within our lives and that of others. It's time to explore what it's like to be transparent

Idasa's Democracy Index - initially developed for South Africa - is being expanded into Southern Africa in an effort to broaden the capacity of individuals and organisations monitoring and supporting democratic governance efforts in the region. This inaugural Democracy Index for Namibia is intended to set a benchmark for democracy to be measured against. The tool assesses the country's depth of democracy through five focus areas: participation, elections, accountability, political rights, and human dignity. The research relies on expert analysis to answer a set of questions that interrogate how closely, in practice, democracy meets the broad ideal of self-representative government. More specifically, to what extent can citizens control elected officials and government appointees who make decisions about public affairs? And how equal are citizens to one another in this accountability process? The purpose of the scores is to assist citizens in making their own judgements, based on the information made available, to stimulate national debate and to provide democracy promoters with a tool for identifying issues and needs that can be addressed by education, advocacy, training, institution building and policy revision.
