The development of modern programmable pacemaker-systems has led to a series of questions which until now have apparently not existed in the treatment of cardiac rhythm disturbances. These questions touch especially on the problem of whether the relation which usually exists between a diagnostic step and its therapeutic consequence, namely its therapeutic relevance, is abolished or at least changed. 相似文献

Compensation decisions have important consequences for employees and organizations and affect factors such as retention, motivation, and recruitment. Past research has primarily focused on mean performance as a predictor of compensation, promoting the implicit assumption that alternative aspects of dynamic performance are not relevant. To address this gap in the literature, we examined the influence of dynamic performance characteristics on compensation decisions in the National Basketball Association (NBA). We predicted that, in addition to performance mean, performance trend and variability would also affect compensation decisions. Results revealed that performance mean and trend, but not variability, were significantly and positively related to changes in compensation levels of NBA players. Moreover, trend (but not mean or variability) predicted compensation when controlling for future performance, suggesting that organizations overweighted trend in their compensation decisions. Theoretical and practical implications are discussed. 相似文献

The need to belong can motivate belief in God. In Study 1, 40 undergraduates read bogus astrophysics articles "proving" God's existence or not offering proof. Participants in the proof-for-God condition reported higher belief in God (compared to control) when they chronically imagined God as accepting but lower belief in God when they imagined God as rejecting. Additionally, in Study 2 (72 undergraduates), these effects did not occur when participants' belongingness need was satisfied by priming close others. Study 3 manipulated 79 Internet participants' image of God. Chronic believers in the God-is-rejecting condition reported lower religious behavioral intentions than chronic believers in the God-is-accepting condition, and this effect was mediated by lower desires for closeness with God. In Study 4 (106 Internet participants), chronic believers with an accepting image of God reported that their belief in God is motivated by belongingness needs. 相似文献

Surveys on sensitive issues provide distorted prevalence estimates when participants fail to respond truthfully. The randomized-response
technique (RRT) encourages more honest responding by adding random noise to responses, thereby removing any direct link between
a participant’s response and his or her true status with regard to a sensitive attribute. However, in spite of the increased
confidentiality, some respondents still refuse to disclose sensitive attitudes or behaviors. To remedy this problem, we propose
an extension of Mangat’s (Journal of the Royal Statistical Society: Series B, 56, 93–95, 1994) variant of the RRT that allows for determining whether participants respond truthfully. This method offers the genuine advantage
of providing undistorted prevalence estimates for sensitive attributes even if respondents fail to respond truthfully. We
show how to implement the method using both closed-form equations and easily accessible free software for multinomial processing
tree models. Moreover, we report the results of two survey experiments that provide evidence for the validity of our extension
of Mangat’s RRT approach. 相似文献

We examined perceptual sequence learning by means of an adapted serial reaction time task in which eye movements were unnecessary for performing the sequence learning task. Participants had to respond to the identity of a target letter pair ("OX" or "XO") appearing in one of four locations. On the other locations, similar distractor letter pairs ("QY" or "YQ") were shown. While target identity changed randomly, target location was structured according to a deterministic sequence. To render eye movements superfluous, (1) stimulus letter pairs appeared around a fixation cross with a visual angle of 0.63°, which means that they appeared within the foveal visual area and (2) the letter pairs were presented for only 100 ms, a period too short to allow proper eye movements. Reliable sequence knowledge was acquired under these conditions, as responses were both slower and less accurate when the trained sequence was replaced by an untrained sequence. These results support the notion that perceptual sequence learning can be based on shifts of attention without overt oculomotor movements. 相似文献
