This paper examines steady states of an overlapping generations economy with a given distribution of household locations over a one-dimensional interval. Parents decide whether or not to educate their children. Such decisions are affected by location: parental aspirations depend on the earnings of their neighbors. At the same time, economy-wide wages endogenously adjust to bring factor supplies...

The paper aims to study the Free/Open source integrated library management systems like Koha, Newgenlib and e-Granthalaya. A thorough analysis of all the three software's has been done and listed the features available in all the three ILMS. Koha and Newgenlib has more advanced and varied features than e-Granthalaya. e-Granthalaya has simple interface with less options and easy to use and insta...

Subproblems have become an important object of NP-completeness theory since its beginning. In this paper, we show some undesirable consequences for subproblems deduced by the standard foundation of the theory, which are different from the practical viewpoint of computation. By the consequences, we clarify further the range in which the standard foundation is applicable to decision problems.

Despite many problems, researchers in the developing nations manage to produce a significant portion of the world’s scientific output. Imagine what these scientists could contribute to the global community if their difficulties could be reduced. The introduction of advanced technologies (such as CDROM) will likely improve scientific communication and education in the developing nations. But jus...

The concept of model transformations is of increasing importance in different areas of Computer Science, but up to now, there is a lack of common understanding concerning the mathematical and practical point of view. In this paper, we discuss some of the different aspects. Especially interesting is the new proposal of the POPL’07 keynote speaker Don Batory claiming that model transformations sh...
