User studies are important for many aspects of the design process and involve techniques ranging from informal surveys to rigorous laboratory studies. However, the costs involved in engaging users often requires practitioners to trade off between sample size, time requirements, and monetary costs

(MAAS) are described. Correlational, quasi-experimental, and laboratory studies then show that the MAAS measures a unique quality of consciousness that is related to a variety of well-being constructs, that differentiates mindfulness practitioners from others, and that is associated with enhanced

managers ’ behavior, 1 how board structure affects oversight activities, 2 and how scale and scope economies affect mutual fund costs and fees. 3 More generally, the fund industry is a laboratory in which to study the actions of individual investors who buy fund shares. In this paper, we study the flows

contended that "attachment behavior [characterizes] human beings from the cradle to the grave" (1979, p. 129). In recent years, laboratory and naturalistic studies of infants and children (summarized by Bretherton, 1985, and We are grateful to Donna Bradshaw for sharing her expertise in the areas

standards: PGP 5.0. Our case study used a cognitive walkthrough analysis together with a laboratory user test to evaluate whether PGP 5.0 can be successfully used by cryptography novices to achieve effective electronic mail security. The analysis found a number of user interface design flaws that may

from 3 experimental studies starkly challenge this implicit assumption that having more choices is necessarily more intrinsically motivating than having fewer. These experiments, which were conducted in both field and laboratory settings, show that people are more likely to purchase gourmet jams

in comparison classes by 15% on standardized tests and 100 % on tests targeting the PUMP objectives. This study provides further evidence that laboratory tutoring systems can be scaled up and made to work, both technically and pedagogically, in real and unforgiving settings like urban high schools. 1.

rejection, the sellers may have an opportunity to post prices again in another round. We study how the duopolists' pricing behavior responds to changes in the likelihood of the buyer observing multiple prices, �, and the probability of continuing to another round, �. The unique equilibrium features

The study of the fluid dynamics of violent volcanic eruptions by laboratory experiment is described, and the important fluid-dynamic processes that can be examined in laboratory models are discussed in detail. In prelim•inary experiments, pure gases are erupted from small reservoirs. The gases used
