...Demography of Germany Concepts, Data, and Methods G. Rohwer U. P¨tter o Version 3 October 2003 Fakult¨t f¨r Sozialwissenschaft a u Ruhr-Universit¨t Bochum, GB 1 a 44780 Bochum goetz.rohwer@ruhr-uni-bochum.de ulrich.poetter@ruhr-uni-bochum.de Preface This text is an introduction to concepts and methods of demographic description and analysis. The substantial focus is on the demographic development of Germany, all data refer to this country. The main reason for this focus on a single country is that we want to show how the tools of demography can actually be used for the analysis of demographic problems. The text consists of two parts. Part I introduces the conceptual framework and explains basic statistical notions. This part also includes a short chapter that explains how we speak of “models” and why we do not make a sharp distinction between “describing” and “modeling” demographic processes. Then follows Part II that deals with data and methods. In the present version of the text, we almost exclusively discuss mortality and fertility data; migration is only mentioned in Chapter 6 and briefly considered in the context of a Leslie model at the end of the text. In addition to providing a general introduction to concepts of demography, the text also intends to show how to practically work with demographic data. We therefore extensively document all the data used and explain the statistical calculations in detail. In fact, most of these calculations are quite simple;...

...saying things like “Look” in a stern voice was necessarily going to get him, and time was not on his side. What the hell, he thought, you’re only young once, and threw himself out of the window. That would at least keep the element of surprise on his side. ... In a spirit of scientific inquiry he hurled himself out of the window again. Douglas Adams Mostly Harmless Strangely, the thing that least intrigued me was how they’d managed to get it all done. I suppose I sort of knew. If I’d learned one thing from traveling, it was that the way to get things done was to go ahead and do them. Don’t talk about going to Borneo.

...INFORMATION TECHNOLOGY FOUNDATION 1 Compiled By: RONKY F. DOH (aka: ronky biggy diggy daddy igp) FU DAME TALS OF COMPUTERS We are living in an information age dependent upon digital information. Digital information is electronic information, the result of computer processing. Every type of job relies upon getting information, using it, managing it, and relaying information to others. Computers enable the efficient processing and storage of information. Do not think of a computer merely as the machine with the keyboard and the mouse, although that might be true for some types of computers. Embedded computers may be inside your household appliances, the video cassette recorder, the automobile, planes, trains, power plants, water purification plants, calculators, and even inside a few toys. These embedded computers are very small. They affect our lives each day. Why, even modern traffic lights operate with computers. They are all around us. Think of additional ways in which computers affect our lives each day. Every organization somehow use(s) a computer to run the organization. Some of the places are hospitals, schools, fire department, banks, stores or supermarkets, stock exchange, police department, insurance companies, transport companies, and government agencies etc. What is a computer? A computer is many things to many people, depending on what it is being used for. At one time the computer can be a machine which processes the payroll, then it can be a machine which tabulates...

...Sams Teach Yourself C in 24 Hours Previous | Table of Contents | Next Hour 1 - Getting Started A journey of a thousand miles is started by taking the first step. —Chinese proverb High thoughts must have high language. —Aristophanes Welcome to Teach Yourself C in 24 Hours. In this first lesson you'll learn the following: What C is Why you need to learn C The ANSI standard Hardware and software required in order to run the C program What Is C? C is a programming language. The C language was first developed in 1972 by Dennis Ritchie at AT&T Bell Labs. Ritchie called his newly developed language C simply because there was a B programming language already. (As a matter of fact, the B language led to the development of C.) C is a high-level programming language. In fact, C is one of the most popular general-purpose programming languages. In the computer world, the further a programming language is from the computer architecture, the higher the language's level. You can imagine that the lowest-level languages are machine languages that computers understand directly. The high-level programming languages, on the other hand, are closer to our human languages. (See Figure 1.1.) Figure 1.1. The language spectrum. High-level programming languages, including C, have the following advantages: Readability: Programs are easy to read. Maintainability: Programs are easy to maintain. Portability: Programs are easy to port across different computer platforms. The...
