In this study, we tested the hypothesis, derived from the theorizing of Derryberry and Tucker (1994), that the mere enactment of approach or avoidance behavior, without concomitant pursuit of personal approach or avoidance goals, can independently moderate the scope (i.e., breadth or narrowness) of attention on both the perceptual and conceptual levels. SpeciWcally, we predicted that enactment ...

Abstrakt In this note we critically examine the current state of teaching of Discrete Simulation at our university. We consider the case study of one of the projects that students are expected to solve in the course. Three approaches are compared nonmodular resulting from the current approach, using Haskell, and using Reactive framework from C#. We conclude that functional approach can address ...

In addition to its intrinsic practical importance, nonlinear time delayed feedback control applied to lifting surfaces can result in interesting aeroelastic behaviors. In this paper, nonlinear aeroelastic response to external time-dependent loads and stability boundary for actively controlled lifting surfaces, in an incompressible flow field, are considered. The structural model and the unstead...

The development of service-oriented applications has reached a point where more specifications are needed to enable holistic transparent service-management. A three-schema-architecture for design of servicebase-management-systems according to the ANSI/SPARC-model for database design is proposed in this paper. The conceptual schema of the proposed architecture decribes the servicebase, what prov...

There exist two formulations of rough sets: the conceptual and computational one. The conceptual or semantical approach of rough set theory focuses on the meaning and interpretation of concepts, while algorithms to compute those concepts are studied in the computational formulation. However, the research on the former is rather limited. In this paper, we focus on a semantically sound approach o...

The functional approach to typology often appeals to processing pressures in order to explain universals. This paper examines a case where the match between a processing asymmetry and a typological asymmetry is not one-to-one — a case where the functional approach appears to fail. For a particular typology of relative clauses, the psycholinguistic literature suggests two asymmetries: accessibil...

We present two (?) problem frames that serve to structure, characterize and analyze software development problems in the area of software and system security. These problem frames constitute patterns for representing security problems, variants of which occur frequently in practice. Solving such problems starts with the development of an appropriate software architecture. To support that proces...

Within the past three years, several new AI textbooks have been published, all written by well-known researchers (Dean, Allen, and Aloiminos 1995; Russell and Norvig 1995; Shoham 1994; Ginsberg 1993). Thus, it is not surprising that the authors of each of these textbooks have sought a way to distinguish their own book from the rest. The hook for Stuart Russell and Peter Norvig's new textbook, A...

We discuss the advantages and disadvantages of a functional approach to clustering of spatial-temporal data. This leads us to suggest an alternative methodology which allows cluster memberships to vary over both temporal and spacial domains. One advantage of our approach is that it can easily incorporate time-varying covariates. A fitting algorithm is developed and we provide a simple simulatio...

Rapid advances in hand-held computing and communication capabilities, decreasing cost of mobile devices, and emergence of standards are fuelling the growth of mobile distributed work arrangement (DWA) in business operations. However, mobile DWA is more than a technological arrangement; it is an organizational innovation that could involve structural and administrative changes in the organizatio...
