  • WendlandDavidW1989.pdf

    Creator:
    Wendland, David W.
    Abstract:
    Castle Rocks is 12 miles east of Mt. Jefferson, in the central Cascades of Oregon. The area contains volcanic rocks ranging from mid-Miocene to Holocene in age. These rocks record alternating periods of tholeiitic and calc-alkaline volcanism. The oldest rocks in the area range from basaltic andesite lava flows to...

  • Protected Area Effectiveness in European Russia: A Postmatching Panel Data Analysis

    Creator:
    Wendland, Kelly J., Baumann, Matthias, Lewis, David J., Sieber, Anika, and Radeloff, Volker C.
    Abstract:
    We estimate the impact of strict and multiple use protected areas on forest disturbance in European Russia between 1985 and 2010. We construct a spatial panel dataset that includes five periods of change. We match protected areas to control observations and compare coefficients from fixed versus random effects models. We...

  • Type systems of object-oriented programming languages

    Creator:
    Sandberg, David W.
    Abstract:
    Three different approaches to type checking have been taken in object-oriented programming languages. Smalltalk-80 uses run-time type checking. C++ uses subtypes. A third alternative is to use parameterized types. We examine the difficulties of programming in an object-oriented fashion with compile-time type checking and argue that parameterized types are better...

  • Smalltalk and exploratory programming

    Creator:
    Sandberg, David W.
    Abstract:
    Using Smalltalk-80, programmers can produce prototypes much faster than with C or Pascal. What techniques do Smalltalk-80 programmers use to produce these prototypes? What is special about Smalltalk-80 that enables them to uses these techniques? Can these techniques be used with conventional languages such as C? In an attempt to...

  • Experience with an object-oriented virtual machine

    Creator:
    Sandberg, David W.
    Abstract:
    Several years ago we began development of an object-based programming language and environment which we call X2. We implemented X2 using a virtual machine similar to Smalltalk-80 implementations, but X2 does no message look-up. The implementation differs from most Smalltalk-80 systems in that objects are paged and in the ability...

  • What is object-oriented programming?

    Creator:
    Sandberg, David W.
    Abstract:
    The term object-oriented is defined. This definition is then related to message-passing, inheritance, polymorphism, data abstraction, generics, and overloading.

  • An alternative to subclassing

    Creator:
    Sandberg, David W.
    Abstract:
    Smalltalk-80 obtains some of its expressive power from arranging classes in a hierarchy. Inheritance is an important aspect of this hierarchy. An alternative organization of classes is proposed that emphasizes description instead of inheritance. This alternative can be used with compile-time type checking and retains the important characteristics of Smalltalk's...
