Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

The main aim of this study is to define the clinical criteria which must be considered in order to come to an adequate decision whether a patient with intracranial arteriovenous malformation (AVM) should be operated upon or treated conservatively. A special method was used to reduce the effects of selection. This method made it possible to evaluate the therapeutic efficacy of conservative treatment versus surgery. The method implies that patients with equal combinations of variables (risk profiles) were compared in the two treatment lines. The variables building up the risk-profile pattern were chosen by analysing the decision process, as it was originally practiced by the surgeon who selected and treated the patients of this study. The risk profiles thus described relevant characteristics of the patient and his malformation. The variables were assigned numerical values accord ing to their prognostic value. Summation of the variables making up the risk profile then gives each risk profile a certain value. A low value symbolizes a bad prognosis and a high value a good prognosis in both treatment groups. There were many risk profiles with the same value in both groups and a comparison could be made over a large part of the risk-profile scale. This comparison showed that surgical treatment of A VM can always be justified, although the indications for surgery are less strong in patients with low risk profile values."

Das Lehrbuch vermittelt statistisches Grundlagenwissen zur Analyse und Beschreibung von verschiedenen empirischen Merkmalen (univariate Statistik). Ausserdem zeigt es die Prufung von Hypothesen uber Zusammenhange zwischen zwei Merkmalen (bivariate Statistik), sowohl "von Hand" als auch mit Unterstutzung von Tabellen-Kalkulationsprogrammen.

Die Wirbelschicht-Spruhgranulation ist eine neue Technologie zur formgebenden Verfestigung von Suspensionen, Losungen und Schmelzen. Das Buch gibt erstmals einen Uberblick uber alle wesentlichen Aspekte dieser Technologie. Theorie und Technik werden in einer fur die unterschiedlich vorgebildeten Interessenten (Chemiker, Ingenieure, Apotheker etc.) leicht fasslichen, reich bebilderten Darstellung vertraut gemacht."

Das Buch widmet sich der Frage, wie die Publikationschance eines Ereignisses neben dem Nachrichtenwert durch die aktuelle Nachrichtenlage und die zeitlichen Produktionsbedingungen beeinflusst wird. Den theoretischen Rahmen dafur bildet der DTA in Verbindung mit der Nachrichtenwerttheorie. Zur Beantwortung wird eine Input-Output-Analyse durchgefuhrt, bei der Material von Nachrichtenagenturen mit der Berichterstattung zweier regionaler Tageszeitungen verglichen wird. Die Ergebnisse zeigen einen hohen Stellenwert des Nachrichtenwerts gegenuber zeitlichen Einflussen und weisen auf einen konkurrenzbedingten Schwellenwert hin.
