    InternetwahlenDemokratische Wahlen über das Internet?
    (Informatik-Spektrum: Vol. 25, No. 2, 2002) Philippsen, Michael
    Nach einer Zusammenstellung und kritischen Diskussion derjenigen Argumente, die Befürworter und Gegner der Durchführung demokratischer Wahlen über das Internet oft vorbringen, bespricht der Artikel die technischen Grundlagen einiger praktikabler Typen von Internetwahlverfahren, die bereits in realen Wahlexperimenten erprobt werden. Dabei werden die Stärken, Schwächen und verbleibenden Risiken deutlich gemacht und bewertet.AbstractAfter a critical discussion of those arguments that are frequently given by both the proponents and the opponents of democratic elections over the Internet, the article presents the technical basics of some Internet voting schemes that are practical and that have already been used in voting experiments. The presentation identifies strength and weaknesses of the schemes and focusses on the remaining risks.

    Towards a more integrated EA planning: linking transformation planning with evolutionary change
    (Enterprise modelling and information systems architectures (EMISA 2011), 2011) Aier, Stephan; Buckl, Sabine; Gleichauf, Bettina; Matthes, Florian; Schweda, Christian M.; Winter, Robert
    Enterprises are subject to continuous change driven by top-down planned transformation projects as well as by bottom-up initiatives realizing what is called the evolution of the enterprise. Enterprise architecture (EA) planning presents itself as a means for facilitating and controlling this change. Nevertheless, the methods and models of EA planning developed in recent years either have a strong focus on planned (proactive) transformations or on guided (reactive) evolution. In this paper, we outline an EA planning method that accounts for both types of enterprise change by illustrating the interplay of EA planning, requirements, release, and synchronization management. Specifically we focus on the coordination of design activities modeled as intermeshed closed-loop control systems and on an integrated information model describing EA transformation planning.
