Design, implementation, and re-engineering of operating systems are still an ambitious undertaking.
Despite, or even because, of the long history of theory and practice in this field, adapting existing systems
to environments of different conditions and requirements as originally specified or assumed, in terms of
functional and/or non-functional respects, is anything but simple. Especially this is true for the embedded
systems domain which, on the one hand, calls for highly specialized and application-aware system abstractions
and, on the other hand, cares a great deal for easily reusable implementations of these abstractions.
The latter aspect becomes more and more important as embedded systems technology is faced with an innovation
cycle decreasing in length. Software for embedded systems needs to be designed for variability, and this
is in particular true for the operating systems of this domain. The paper discusses dimensions of variability
that need to be considered in the development of embedded operating systems and presents approaches that
aid construction and maintenance of evolutionary operating systems.

Culture impedes educational transactions between developed countries, and is often an area of tension when developing countries try to borrow models, or have models imposed upon them. This article uses the German Dual System as a case for examining issues surrounding the adaptation of borrowed models. Since attempts at borrowing models can fail for cultural as well as non‐cultural reasons, a contention here is that culture needs to be unpacked and laid bare, to avoid it becoming the too easy answer for failure. Borrowed models have a greater chance of taking hold, if the conditions that forged them are understood, and if conditions of the receiving country are likewise internalized. Limits imposed by culture have to be recognized. Four approaches to cultural borrowing that conceivably can reduce the tensions are proposed namely, partial borrowing, pilot borrowing, customization and conceptual borrowing. 相似文献
