Factors affecting performance on Base-10 tasks were investigated in a series of four studies with a total of 453 children aged five to seven years. Training in counting-on was found to enhance child performance on Base-10 tasks (Studies 2, 3, and 4), while prior knowledge of counting-on (Study 1), trading (Studies 1 and 3) and partitioning (Studies 1 and 4) were associated with enhanced Base-10...

The authors develop the concept of regional systems of innovation and relate it to preexisting research on national systems of innovation. They argue that work conducted in the 'new regional science' field is complementary to systems of innovation approaches. They seek to link new regional work to evolutionary economics, and argue for the development of evolutionary regional science. Common ele...

Diversijication by incumbent telecommunications companies raises many issues for regulators. Given the concerns expressed by potential competitors antl.some ·consumergroups, it is important for regulatory commissions to adopt costing principles that cannot be manipulated bypmticipants in the hearing process. Incremental cost is offered as the benchmark conceptforidentifyingpredation and cross-s...

Two major methods of explaining economic institutions are compared for the case of a homogenous quadratic duopoly market. In the indirect evolutionary approach, sellers may evolve to care for sales, in addition to profit. In the strategic delegation approach, sellers may design incentives so that their agents care for sales. The two approaches model different phenomena, but both allow certain k...

Interactive pricing mechanisms integrate customers into the price-setting process by letting them submit bids. Name-your-own-price auctions are such an interactive pricing mechanism, where buyers’ bids denote the final price of a product or service in case they surpass a secret threshold price set by the seller. If buyers are given the flexibility to bid repeatedly, they might try to incrementa...

The explosion in the amount of data available for analysis often necessitates a transition from batch to incremental clustering methods, which process one element at a time and typically store only a small subset of the data. In this paper, we initiate the formal analysis of incremental clustering methods focusing on the types of cluster structure that they are able to detect. We find that the ...

Multi-context systems provide a powerful framework for modelling informationaggregation systems featuring heterogeneous reasoning components. Their execution can, however, incur non-negligible cost. Here, we focus on cost-complexity of such systems. To that end, we introduce cost-aware multi-context systems, an extension of non-monotonic multi-context systems framework taking into account costs...

Mass-marketing frauds (MMFs) are on the increase. Given the amount of monies lost and the psychological impact of MMFs there is an urgent need to develop new and effective methods to prevent more of these crimes. This paper reports the early planning of automated methods our interdisciplinary team are developing to prevent and detect MMF. Importantly, the paper presents the ethical and social c...

The incremental parsing (IP) algorithm has been successfully used in real-time applications, due to its efficiency and power to model musical style. For example, musical systems using IP can continue phrases played by a musician in a consistent way. This paper proposes some alterations in the original algorithm in order to adapt it to accompaniment systems.
