Diese Arbeit beschreibt die Entwicklung englischer Partizipial- und Gerundialkonstruktionen in mittelenglischer und frühneuenglischer Zeit und untersucht dabei die Funktion von Textsorten im Prozeß des Sprachwandels. Aufbauend auf einer detaillierten Analyse sämtlicher Partizipial- und Gerundialkonstruktionen in sechs Textsorten einer überarbeiteten und erweiterten Fassung des Helsinki-Korpus wird gezeigt, daß sich die Hauptkonstruktionstypen in einer geordneten Reihenfolge über Textsorten ausbreiten. Die Funktion von Textsorten im Sprachwandel kann dabei als Katalysatorenfunktion bestimmt werden. Textsorten sind für die Ausbreitung, nicht aber für die Entstehung einer Konstruktion verantwortlich. Die Katalysatorenfunktion basiert einerseits auf dem spezifischen funktionalen Profil der Textsorten, andererseits auf ihrer Position innerhalb der Sozial- und Kulturgeschichte der englischen Sprache.Textsortenabhängiger Sprachwandel, wie er sich in der Ausbreitung von Partizipial- und Gerundialkonstruktionen zeigt, wird als Beispiel für die Elaborierungsphase im Prozeß der Standardisierung und der Ausbreitung von Schriftlichkeit gewertet.

The topic of the third volume of the series in "Essentials in Ophthalmology" is cataract and refractive surgery, a realm of ophthalmic care that has undergone revolutionary changes in the past 10 years. Worldwide, the removal of the opaque crystalline lens is the most frequently performed surgical intervention in the human body, and refractive surgery encompasses an increasing array of procedures with rapidly growing surgical volumes. The goal of the editors of this book has been to provide up-to-date clinically relevant overviews and to highlight the most interesting fields of research and controversy.

This book is written for students of English who are interested in the history of the language and would like to read an accessible but also comprehensive and reasonably detailed introduction. Apart from basic information about language change and the Indo-European background of English, it gives an outline of the major periods of the language (Old English, Middle English, Early Modern English and Late Modern English), with a brief examination of the perspectives of present-day English. Each period chapter provides information about the socio-historical background, the core areas of linguistic structure, discourse, speech acts and genres, and concludes with study questions and exercises.
