This book is intended as a textbook for a first course in applied statistics for students of economics, public administration and business administration. A limited knowledge of mathematics and - in one single chapter - some knowledge of elementary matrix algebra is required for understanding the text. Complicated mathematical proofs are avoided and the explanations are based on intuition and numerical examples. The aim of this book is to enable the student to understand the reasoning underlying a statistical analysis and to apply statistical methods to problems likely to be met within the...

Water bugs are familiar insects in aquatic habitats throughout the World. They belong to the order Hemiptera, the largest insect order with incomplete metamorphosis. There are basically two kinds: (1) the semiaquatic bugs (Gerromorpha) which live upon the water surface, and (2) the true water bugs (Nepomorpha) which live beneath the water surface. Water bugs are found in a wide variety of natural habitats from small, temporary pools to larger ponds and lakes, from small streams to rivers, and from inland freshwater bodies to coastal mangroves, tidal pools of coral reefs, and the surface of...

Graduate text/monograph on polarization, alignment, and orientation effects in atomic collisions, induced by electron or heavy particle impact. The first part of the book presents introductory chapters on light and particle polarization, experimenatal and computational methods, and the density matrix and state multipole formalism. Examples and exercises are included. The second part of the book includes case studies of electron impact and heavy particle excitation, electron transfer, impact ionization and autoionization. Last chapter discusses related topics and applications. The book will...
