This paper reports the results of experiments designed to test the theory of the optimal composition of prizes in contests. In the aggregate the behavior of subjects is consistent with that predicted by the theory, but we find that such aggregate results mask an unexpected compositional effect on the individual level. Whereas theory predicts that subject efforts are continuous and increasing fu...

The employment effects of training programs for the unemployed are frequently studied, but little is known about the number, the characteristics, and the labor market prospects of those who drop out of these programs. The aim of this paper is to contribute to filling this gap. Using German administrative data it turns out that one out of five participants of further training programs drops out ...

Design of a clinical study to determine the impact of an experimental agent or regimen on dental caries activity must balance a number of interacting variables to yield meaningful results. At the outset, caries experience must be determined for each subject to permit sample stratification that will, in addition to age and sex, divide dental caries risk equally between the experimental groups. U...

In this article, we investigate a novel anytime control algorithm for wireless networked with random dropouts. The controller computes sequences of tentative future commands using time-varying (Markovian) computational resources. sensor–controller and controller–actuator channel states are spatial- time-correlated, respectively, modeled as multistate Markov process. To compensate the effect pac...

conclusions the individual characteristics, educational background and admission criteria had showed relation with academic failure. vulnerable students should be identified and educational supports should be provided for these students. results the frequency of course repetition, probation, and delayed graduation was reported to be 19.25%, 3.9% and 19.85%, respectively. gaining low grade in hi...

Dropout is a phenomenon that unfortunately occurring worldwide and of increasing concern to authorities. It reality quality indicators in many models are affected by the number students who drop out school at higher levels. However, this not only reflected educational level, but also affects social personal development young people. The analysis dropout among Spaniards topic interest due reperc...

We consider a class of networked control systems (NCSs) where the plant has time-varying norm-bounded parameter uncertainties, the network only provides a limited number of simultaneous accesses for the sensors and actuators, and the packet dropouts occur randomly in the network. For this class of NCSs with uncertainties and access constraints as well as packet dropouts, we derive sufficient co...
