Es richtet sich gleichermaAen an Praktiker in Dienstleistungsunternehmen und Affentlichen Verwaltungen sowie an Mitarbeiter produzierender Unternehmen, die ihr Dienstleistungsangebot systematisieren und ausbauen wollen.

Die Integration von Informationssystemen beschrankt sich selten auf die Veranderung von Softwarekomponenten und Datenstrukturen oder die Veranderung von IT-Infrastrukturkomponenten. Meist sind ebenso Produkte, Geschaftsprozesse oder Organisationsstrukturen, also fachliche Unternehmensstrukturen betroffen. Das Buch hat zum Ziel, einen grundlegenden Beitrag zur situativen Methodik-Unterstutzung der Planung und Umsetzung von Integrationsprojekten zu leisten. Um dies zu realisieren, wird eine Strukturierung der Integration aus Metamodellierungs-Perspektive vorgenommen. Es werden Archetypen der Integration formuliert und typische Situationen fur Integrationsprojekte beschrieben. Zahlreiche Fallstudien zu Integrationsprojekten liefern erste Erkenntnisse uber die Wiederkehr grundlegender Integrationsaufgaben in bestimmten Integrations-Situationen. Darauf aufbauend wird eine erste Annaherung an eine situationsbezogene, anpassbare Integrationsmethodik vorgestellt."

Das Buch zeigt, welche Potentiale sich f r Unternehmen durch eine konsequente Orientierung an den Kundenprozessen und einer kooperativen Zusammenarbeit zwischen Unternehmen ergeben. Eine wichtige Rolle nehmen dabei elektronische Dienstleister (sogenannte WebService-Anbieter) ein, die diese Kooperationsprozesse erst erm glichen oder die elektronischen Services viel effizienter erbringen als jedes einzelne Unternehmen im Netzwerkverbund, z.B. f r den Zahlungsverkehr und die Logistik. Dazu werden anhand anschaulicher Beispiele aus der Praxis methodische Vorschl ge zur Gestaltung des Kundenprozesses, zum Portaldesign und zur Kooperationsprozessanalyse und Out-tasking sowie Architekturen f r Kooperationsprozesse und WebServices entwickelt.

The most widely used statistical method in seasonal adjustment is without doubt that implemented in the X-11 Variant of the Census Method II Seasonal Adjustment Program. Developed at the US Bureau of the Census in the 1950's and 1960's, this computer program has undergone numerous modifications and improvements, leading especially to the X-11-ARIMA software packages in 1975 and 1988 and X-12-ARIMA, the first beta version of which is dated 1998. While these software packages integrate, to varying degrees, parametric methods, and especially the ARIMA models popularized by Box and Jenkins, they remain in essence very close to the initial X-11 method, and it is this "core" that Seasonal Adjustment with the X-11 Method focuses on. With a Preface by Allan Young, the authors document the seasonal adjustment method implemented in the X-11 based software. It will be an important reference for government agencies, macroeconomists, and other serious users of economic data. After some historical notes, the authors outline the X-11 methodology. One chapter is devoted to the study of moving averages with an emphasis on those used by X-11. Readers will also find a complete example of seasonal adjustment, and have a detailed picture of all the calculations. The linear regression models used for trading-day effects and the process of detecting and correcting extreme values are studied in the example. The estimation of the Easter effect is dealt with in a separate chapter insofar as the models used in X-11-ARIMA and X-12-ARIMA are appreciably different.

Wenn heute uber Informationstechnik in der offentlichen Verwaltung" geschr- ben oder geredet wird, geschieht dies meist im Kontext von Electronic Gove- ment," wobei diese Thematik dann auch noch haufig auf die Bereitstellung el- tronischer Burgerservices reduziert wird. Dabei hat die offentliche Verwaltung selbstverstandlich schon lange vor der Verbreitung des Internets massiven Gebrauch von der Informationstechnik - macht - nur blieb die Auseinandersetzung damit lange Zeit einem sehr kleinen Kreis von Praktikern und Wissenschaftlern vorbehalten. Ursachlich dafur war - niger der Wunsch nach Exklusivitat, sondern vor allem der Umstand, dass sich ausserhalb dieses Kreises kaum jemand fur das Thema erwarmen konnte. Im Zuge von E-Government hat sich diese Situation schlagartig geandert. Die Anzahl der Kongresse, Messen, Umfragen, Benchmarkings usw. zum Thema hat in den letzten Jahren zwar spurbar nachgelassen, doch nach wie vor wird E- Government von denen, die sich damit beschaftigen (und das sind heute noch - mer sehr viel mehr Personen als noch vor zehn Jahren), als zentrales Instrument zur Modernisierung des Behordenapparats angesehen. Inzwischen wissen wir aber auch, dass gerade strukturelle Veranderungen vielfach sehr schleppend verlaufen und die IT im offentlichen Sektor noch immer nicht die Durchschlagskraft" - reicht hat, die ihr vielfach zugeschrieben wurde und die angesichts der technischen Moglichkeiten auch ohne weiteres vorstellbar ist. Fur das eher zogerliche Aufgr- fen der mit moderner IT eroffneten Veranderungsoptionen gibt es zahlreiche Grunde, von denen in den nachfolgenden Beitragen immer wieder die Rede sein wird."

It is generally accepted that training in statistics must include some exposure to the mechanics of computational statistics. This learning guide is intended for beginners in computer-aided statistical data analysis. The prerequisites for XploRe - the statistical computing environment - are an introductory course in statistics or mathematics. The reader of this book should be familiar with basic elements of matrix algebra and the use of HTML browsers. This guide is designed to help students to XploRe their data, to learn (via data interaction) about statistical methods and to disseminate their findings via the HTML outlet. The XploRe APSS (Auto Pilot Support System) is a powerful tool for finding the appropriate statistical technique (quantlet) for the data under analysis. Homogeneous quantlets are combined in XploRe into quantlibs. The XploRe language is intuitive and users with prior experience of other sta tistical programs will find it easy to reproduce the examples explained in this guide. The quantlets in this guide are available on the CD-ROM as well as on the Internet. The statistical operations that the student is guided into range from basic one-dimensional data analysis to more complicated tasks such as time series analysis, multivariate graphics construction, microeconometrics, panel data analysis, etc. The guide starts with a simple data analysis of pullover sales data, then in troduces graphics. The graphics are interactive and cover a wide range of dis plays of statistical data."

Increasing the designer's con dence that a piece of software or hardwareis c- pliant with its speci cation has become a key objective in the design process for software and hardware systems. Many approaches to reaching this goal have been developed, including rigorous speci cation, formal veri cation, automated validation, and testing. Finite-state model checking, as it is supported by the explicit-state model checkerSPIN, is enjoying a constantly increasingpopularity in automated property validation of concurrent, message based systems. SPIN has been in large parts implemented and is being maintained by Gerard Ho- mann, and is freely available via ftp fromnetlib.bell-labs.comor from URL http: //cm.bell-labs.com/cm/cs/what/spin/Man/README.html. The beauty of nite-state model checking lies in the possibility of building \push-button" validation tools. When the state space is nite, the state-space traversal will eventually terminate with a de nite verdict on the property that is being validated. Equally helpful is the fact that in case the property is inv- idated the model checker will return a counterexample, a feature that greatly facilitates fault identi cation. On the downside, the time it takes to obtain a verdict may be very long if the state space is large and the type of properties that can be validated is restricted to a logic of rather limited expressiveness.
