This chapter describes four systems that introduce new pedagogy, address inequities in the classroom and show improved learning with reduced cost. The first system supports inquiry and casebased learning, moving students towards more active learning, engagement, and hypothesis construction. The next system describes mathematics and geometry tutors that positively influence a student’s confidenc...

behaviour studies indicated that the permethrin resistant strin of an. stephensi was 3-fold resistant to knock-down compared with the susceptible strain. the resistant strain was however 3-fold less irritable to permethrin and less responsive than the susceptible strain to the movement of an aspirator. if reduced irritability and reduced responsiveness to catch are consequences of the changes i...

Optical scan voting systems are ubiquitous. Unfortunately, optical scan technology is vulnerable to failures that can result in miscounted votes and lost confidence. While manual counts may be able to detect these failures, counting all the ballots by hand is in many situations impractical and prohibitively expensive. In this paper, we present a novel approach for examining a large set of ballo...

The Busse–Heikes dynamical model is described in terms of relaxational and non-relaxational dynamics. Within this dynamical picture a diverging alternating period is calculated in a reduced dynamics given by a time-dependent Hamiltonian with decreasing energy. A mean period is calculated which results from noise stabilization of a mean energy. The consideration of spatial-dependent amplitudes l...

This paper examines the motivations for the construction of consumer decision tools (CDTs). CDTs are Web-based decision support systems aimed at improving the quality of consumer decisions. CDTs are useful for high involvement choices, such as car or university programme selection, where the consumer is strongly affected by the outcome. Firms will supply CDTs only when they desire informed, mut...

Previous research has found that iconic gestures (i.e., gestures that depict the actions, motions or shapes of entities) identify referents that are also lexically specified in the co-occurring speech produced by proficient speakers. This study examines whether concrete deictic gestures (i.e., gestures that point to physical entities) bear a different kind of relation to speech, and whether thi...

This paper investigates bloatware bundling and product pricing decisions of a monopolistic firm when consumers can remove the bloatware from their electronic devices after purchase. We show conditions under which it is optimal for the firm not to bundle bloatware with their products. Furthermore, we show that even if the firm can make it harder for consumers to remove bloatware, the firm is not...

The Busse-Heikes dynamical model is described in terms of relaxational and nonre-laxational dynamics. Within this dynamical picture a diverging alternating period is calculated in a reduced dynamics given by a time-dependent Hamiltonian with decreasing energy. A mean period is calculated which results from noise stabilization of a mean energy. The consideration of spatial-dependent amplitudes l...

In this paper, we investigate the reduced form of circulant matrices and we show that the problem of computing the q-th roots of a nonsingular circulant matrix A can be reduced to that of computing the q-th roots of two half size matrices B - C and B + C.
