Although I feel honored to write a foreword for this important book, it is a task that I approach with some trepidation. The topics covered in the book summarize the current state of the art in technical demography. However, my knowledge and expertise with respect to technical demography are limited to the most fundamental and intermediate-level methods; hence, critical commentary on the contents of this volume is beyond my scope in this fore word. Since I have some understanding of the logic and substantive aspects of the methods rather than the complicated mathematics used in describing them, my comments will necessarily be restricted to the book's general or ganization and content. To date, most texts published on technical demography have been limited to traditional demographic methods: sources and limitations of data, life table construction and applications, standardization techniques, various methods for preparing population estimates and forecasts, etc. However, population specialists have in recent years been developing and successfully applying a variety of sophisticated techniques not covered in the more standard intro ductory texts. In addition, many traditional methods that are unique to the demographic discipline have been improved and extended."

Provides information needed to design millimeter-wave microstrip and printed circuit antennas from analysis methods and materials selection to antennas for particular applications. Special focus is given to the issues that impact the ability to scale microwave frequency designs to the millimeter-wav

the accent and emphasis in educational research will be altogether different from the one when it is constructed mainly as a practice or as an activity performed by the society to produce and sustain its social, cultural, and economic potentialities. The major topics dealt in this book are: Sphere of Educational Research; Kinds of Educational Research; Intelligence Tests; Sampling in Research; Experimental Methods; Historical Methods; Hypothesis in Research; Research Design; Processing and Presentation of Research Data; Presentation of Research Report; etc.

Research involves systematic investigation of a subject in order to establish the facts and arrive at a new conclusions. It being a crucial endeavour, the researcher needs to cultivate a scientific outlook. This book aims to help develop the scientific temper required to carry out research work in the fields of commerce and management in a meaningful way. Multiple examples showing methods of conducting investigation in these fields are provided. It explains the complexities of research methodology in a simple and lucid manner. Hence, trying to fill the gap in the existing literature on the subject.
