A new wind tunnel testing process under development at NASA Langley Research Center, called Modern Design of Experiments (MDOE), differs from conventional wind tunnel testing techniques on a number of levels. Chief among these is that MDOE focuses on the generation of adequate prediction models rather than high-volume data collection. Some cultural issues attached to this and other distinctions...

This paper analyzes experimentally how the interaction of task meaning and peer presence affects work effort. We build on the experimental designs of Falk and Ichino (2006) and Ariely et al. (2008). Confirming previous results from the literature, we find positive peer effects and negative effects of low task meaning. In addition, we find that peer effects are even stronger if task meaning is l...

We present a Bayesian translational model for matching patterns in data sets which have neither co-occurring samples nor variables, but only a similar experiment design dividing the samples into two or more categories. The model estimates covariate effects related to this design and separates the factors that are shared across the data sets from those specific to one data set. The model is desi...

In the present research we analyze the interrelations of spatial distance and efficaciousness in helping needy others, and we investigate how these factors affect our judgments of moral helping obligations. The main question is under which conditions the location of an agent’s means of helping relative to a victim is regarded as morally relevant. We develop a new experimental design that allows...

Evidence from studies in international relations, the politics of reform, collective action and price competition suggests that economic agents in social dilemma situations cooperate more to avoid losses than in the pursuit of gains. To test whether the prospect of losses can induce cooperation, we let experimental subjects play the traveler’s dilemma in the gain and loss domain. Subjects coope...

Using a computational testbed, we theoretically predict and experimentally show that in the minimum effort coordination game, as the cost of effort increases, 1) the game converges to lower effort levels, 2) the convergence speed increases, and 3) the average payoff is not monotonically decreasing. In fact, the average profit is an U-shaped curve as a function of cost. Therefore, contrary to th...

In undergoing this life, many people always try to do and get the best. New knowledge, experience, lesson, and everything that can improve the life will be done. However, many people sometimes feel confused to get those things. Feeling the limited of experience and sources to be better is one of the lacks to own. However, there is a very simple thing that can be done. This is what your teacher ...
