Cycle switches are the simplest changes which can be used to alter latin squares, and as such have found many applications in the generation of latin squares. They also provide the simplest examples of latin interchanges or trades in latin square designs. In this paper we construct graphs in which the vertices are classes of latin squares. Edges arise from switching cycles to move from one clas...

Our study investigates the antecedents and performance implications of cooperative exchange norms. We argue that, in early relationships, the level of expected cooperative norms in an exchange is the result of a calculative process facilitated by transaction attributes: joint transaction-specific investments and observability. The greater the level of these two exchange attributes, the greater ...

We study a modification of the so-called Parrondo’s paradox where a large number of individuals choose the game they want to play by voting. We show that it can be better for the players to vote randomly than to vote according to their own benefit in one turn. The former yields a winning tendency while the latter results in steady losses. An explanation of this behaviour is given by noting that...

Perceived quality, expectations, customer satisfaction, and effect of customer satisfaction on repurchase likelihood are found to be higher for products than for services, but repurchase likelihood for products is lower. Retailers have the highest repurchase likelihood and score lowest on the other variables. A set of relevant category characteristics is used to further understand variation in ...

Dry-type air-core shunt reactors are now being used more frequently on high voltage power transmission systems to limit overvoltages. Recently, high voltage dry-type air-core shunt reactors have been designed, manufactured and installed directly connected to the transmission systems at voltages up to and including 345 kV. Applications at 500 kV are presently being considered. These ratings requ...

Network-based real-time multimedia applications require guaranteed performance communicationservices. To provide guaranteed service, resources have to be reserved within the network. If reservation is based on the peak rate of each connection, the network will be under-utilized by guaranteed service traffic when the traffic is bursty. In this paper, we first show that local deterministic delay ...

Children diagnosed with Specific Language Impairment (SLI) experience a delay in acquisition of certain language skills, with no evidence of hearing impediments, or other cognitive, behavioral, or overt neurological problems (Leonard, 1991; Paradis et al., 2005/6). Standardized tests, such as the Test for Early Grammatical Impairment, have shown to have great predictive value for assessing Engl...
