  text: "The textual Object Constraint Language (OCL) is an of-\r\nficial part of
    the Unified Modeling Language (UML). OCL\r\nis primarily used to formulate restrictions
    over UML mod-\r\nels, in particular, invariants and operation pre- and post-\r\nconditions
    in the context of class diagrams. However, OCL\r\nis missing means to specify
    constraints over the dynamic\r\nbehavior of a UML model. We have therefore developed
    a\r\ntemporal extension of OCL that enables modelers to specify\r\nbehavioral
    state-oriented constraints. That work provides\r\nan alternative to the rather
    cryptic temporal logic formulae\r\nthat are commonly used to specify behavioral
    system prop-\r\nerties.\r\nThis article now illustrates that our OCL extension
    al-\r\nlows for specifying all kinds of properties that are regarded\r\nas relevant
    in practice. We present according temporal OCL\r\nexpressions for property specification
    patterns that have\r\nbeen identified in the area of formal specification."

  text: "The Object Constraint Language (OCL) was introduced to support the specification
    of constraints for UML diagrams and is mainly used to formulate invariants and
    operation pre- and postconditions. Though OCL is also applied in behavioral diagrams,
    e.g., as guards for state transitions, it is currently not possible to specify
    constraints concerning the dynamic behavior and timing properties of such diagrams.\r\n\r\nThis
    article discusses OCL’s application for the dynamic behavior of UML Statechart
    diagrams and presents an OCL extension for specification of state-oriented time-bounded
    constraints.We introduce operations to extract state configurations from diagrams
    and define additional predicates over states and state configurations. The semantics
    of our OCL extension is given by employing time-bounded Computational Tree Logic
    (CTL) formulae. An example of a flexible manufacturing system with automated guided
    vehicles demonstrates the application of our extension."

  text: The Unified Modeling Language (UML) has received wide acceptance as a standard
    language in the field of software specification by means of different diagram
    types. In a recent version of UML, the textual Object Constraint Language (OCL)
    was introduced to support specification of constraints for UML models. But OCL
    currently does not provide sufficient means to specify constraints over the dynamic
    behavior of a model. This article presents an OCL extension that is consistent
    with current OCL and enables modelers to specify state-related time-bounded constraints.
    We consider the case study of a flexible manufacturing system and identify typical
    real-time constraints. The constraints are presented in our temporal OCL extension
    as well as in temporal logic formulae. For general application, we define a semantics
    of our OCL extension by means of a time-bounded temporal logic based on Computational
    Tree Logic (CTL).

  text: "Two parameters of language production, the partner model and the mentally
    represented knowledge\r\nabout a spatial constellation, are investigated with
    respect to their influence on spatial reference. At\r\nissue is whether the verbally
    expressed point of view in route directions is primarily influenced by the\r\nneeds
    of the partner or by the underlying mental representation of the speaker stemming
    from his or\r\nher own experience with an object. Two experiments in which participants
    (N 5 90) were asked to\r\nproduce a set of route directions are reported. The
    experimental situation was such that the point of\r\nview of the speaker did not
    correspond to the point of view of the partner. The results show that more\r\nparticipants
    localize from their own point of view than from the point of view of the partner.\r\nDiscussion
    centers on the fact that speakers do not always behave in a truly partner-oriented
    manner."
