Weeds are a fascinating study for specialists, not only because of their economic importance, but also since in this case biology must be combined with history and agriculture (and its economic aspects). Thus, weed scientists may be concerned with pure basic research, concentrating on general aspects, or with applied science, i.e. having a practical orientation. One of the aims of this book is to create a synthesis between these two branches of study and to review the literature of both fields. The agrestals, the weeds of arable land ~ the most important group from an economic point of view ~ was chasen as the main topic. Other weed groups could only be mentioned briefly (e.g. grassland weeds), or superficially (e.g. aquatic weeds), or had to be omitted completely (e.g. ruderals, because they are so heterogeneous), to keep this volume to an acceptable size and price. Nevertheless, nearly all subsections of botanical science have been treated.

Few subjects in gynecology, let alone in medicine in general, have provoked such inter est or study as cervical cancer. Although the wealth of monographs and books publish ed on the subject would seem to obviate the need for more, the great advances made in the medical sciences and in gynecological experience and techniques in recent years call for, if not require, a new book on cervical cancer to bring together the latest ideas and trends in its methods of study, diagnosis, and treatment. Although precancerous lesions have become more common, the number of women developing invasive cervical carcinomas has not increased, owing in part to programs of patient education, in part to screening examinations sponsored by the government. The gynecologist is now able to detect with well-tried and proved techniques precan cerous states of the cervix, and to treat these effectively before they become invasive cancer. Accordingly, recent interests in cervical cancer have shifted from the classic descrip tion of invasive carcinoma to newer studies of cause, diagnosis, therapy, and terminol ogy of its precursors. As the reader will learn, epidemiological studies as guides for the future account for, and justifiably so, an important part of this book. New knowledge about changes in the morphology of cervical carcinoma confirms its dependency on hormonal stimulation. Furthermore, modem experiences serve to explain which therapy is best. Overlapping of concepts and opinions between some chapters could not be avoided."

We have edited this book in honour ofMakoto Numata, the nestor of Japanese plant ecology, who will celebrate his 65th birthday in November 1982 and will be retiring from office in March 1983. As the main concern of his work during the last years was to educate people in ecological understanding - probably the only possibility for mankind to master the 'environmental problems' - the topic chosen for this book seemed the most suitable one to honour the retiree. We hope that this volume will prove to be useful for many in carrying through this important task of modern ecology. We are grateful to the authors and particularly to Mr. Peters and the staff of Dr. W. Junk publishers for their patient cooperation. We are also indebted to Jan Knaapen for making the index.

You've probably heard the buzz about Eclipse, the powerful open source platform that gives Java developers a new way to approach development projects. It's like a shiny new car--no longer content to just admire Eclipse, you're now itching to get in and drive.

Eclipse is to Java developers what Visual Studio is to .NET developers--it's an integrated development environment (IDE) that combines a code editor, compiler, debugger, text editor, graphical user interface (GUI) builder, and other components into a single, user-friendly application. It provides a solid foundation that enables Java developers to construct and run integrated software-development tools for web development, application design, modeling, performance, testing, and much more.

As with any extensive programming tool, however, there's a lot to learn. And there s no better guy than well-known Java expert Steve Holzner to teach you. An award-winning and best-selling author who has been writing about Java topics since the language first appeared, Holzner delivers just the kind of targeted, practical, everyday knowledge you need to hone your mastery of Eclipse.

Perfect as a companion to an Eclipse programming tutorial (such as Holzner's own Eclipse, O'Reilly, April 2004) or an ideal stand-alone for all those developers who either don't want or don't need the tutorial approach, the "Eclipse Cookbook" contains task-oriented recipes for more than 800 situations you may encounter while using this new Java platform--from deploying a web application automatically to reverse engineering compiled code, from re-naming all references to a class across multiple packages to initializing the SWT JNI libraries.

Each recipein the ever-popular and utterly practical problem-solution-discussion format for O'Reilly cookbooks contains a clear and thorough description of the problem, a brief but complete discussion of a solution, and in-action examples illustrating that solution. The "Eclipse Cookbook" will satiate Java programmers at all levels who are ready to go beyond tutorials--far beyond writing plug-ins and extensions--and actually use the powerful and convenient Eclipse day to day.

Java programmers know how finicky Java can be to work with. An omitted semi-colon or the slightest typo will cause the Java command-line compiler to spew pages of annoying error messages across your screen. And it doesn't fix them--that's up to you: fix them, compile again, and hope that nothing goes wrong this time.

Eclipse, the popular Java integrated development environment (IDE) provides an elegant and powerful remedy for this common, frustrating scenario. It doesn't just catch your errors before you compile, it also suggests solutions. All you need to do is point and click. And it's free--what could be better? Still, if you're like most programmers, mastering a new technology--no matter how productive it will make you in the long run--is going to take a chunk out of your productivity now. You want to get up to speed quickly without sacrificing efficiency.

O'Reilly's new guide to the technology, "Eclipse," provides exactly what you're looking for: a fast-track approach to mastery of Eclipse. This insightful, hands-on book delivers clear and concise coverage, with no fluff, that gets down to business immediately. The book is tightly focused, covering all aspects of Eclipse: the menus, preferences, views, perspectives, editors, team and debugging techniques, and how they're used every day by thousands of developers. Development of practical skills is emphasized with dozens of examples presented throughout the book.

From cover-to-cover, the book is pure Eclipse, covering hundreds of techniques beginning with the most basic Java development through creating your own plug-in editors for the Eclipse environment. Some of the topics you'll learn about include:

Using Eclipseto develop Java code

Testing and debugging

Working in teams using CVS

Building Eclipse projects using Ant

The Standard Widget Toolkit (SWT)

Web development

Developing Struts applications with Eclipse

From basics to advanced topics, "Eclipse" takes you through the fundamentals of Eclipse and more. You may be an Eclipse novice when you pick up the book, but you'll be a pro by the time you've finished.

The first large-scale study of political participation in eighteen Latin American democracies, focusing on the political participation of the region's poorest citizens. Political regimes in Latin America have a long history of excluding poor people from politics. Today, the region's democracies survive in contexts that are still marked by deep poverty and some of the world's most severe socioeconomic inequalities. Keeping socioeconomic inequality from spilling over into political inequality is one of the core challenges facing these young democracies. In Voice and Inequality, Carew Boulding and Claudio Holzner offer the first large-scale empirical analysis of political participation in Latin America. They find that in recent years, most (but not all) countries in the region have achieved near equality of participation across wealth groups, and in some cases poor people participate more than wealthier individuals. How can this be, given the long history of excluding poor people from the political arena in Latin America? Boulding and Holzner argue that key institutions of democracy, namely civil society, political parties, and competitive elections, have an enormous impact on whether or not poor people turn out to vote, protest, and contact government officials. Far from being politically inert, under certain conditions the poorest citizens can act and speak for themselves with an intensity that far exceeds their modest socioeconomic resources. When voluntary organizations thrive in poor communities and when political parties focus their mobilization efforts on poor individuals, they respond with high levels of political activism. Poor people's activism also benefits from strong parties, robust electoral competition and well-functioning democratic institutions. Where electoral competition is robust and where the power of incumbents is constrained, the authors find higher levels of participation by poor individuals and more political equality. Precisely because the individual resource constraints that poor people face are daunting obstacles to political activism, Voice and Inequality focuses on the features of democratic politics that create opportunities for participation that have the strongest impact on poor people's political behavior. Ultimately, Voice and Inequality provides important insights about how the elusive goal of political equality can be achieved even in contexts of elevated poverty and inequality.
