In Experiment 1, water-deprived Sprague-Dawley rats were given 5 min access to saccharin. This tube retracted, an empty tube advanced, and the rats were given 1 hr to lick the empty tube on a fixed-ratio 10 lick contingency to self-administer saline or cocaine (0.33 mg/infusion) via an intravenous catheter. The results showed that rats avoided intake of saccharin after saccharin-cocaine pairings and that greater avoidance of the gustatory cue was associated with greater cocaine self-administration. In Experiment 2, a similar dose-response function was obtained with either the empty tube or a lever as the operant. In Experiment 3, avoidance of the saccharin cue and the propensity to self-administer cocaine were maintained after at least 1 month of abstinence. As such, this paradigm may be useful as a model of cue-induced craving and drug-induced devaluation of natural rewards. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Two studies of task-focused dyads tested the approach/inhibition theory of power (P. Keltner, D. H. Gruenfeld, & C. Anderson, in press), which posits that having power increases the tendency to approach and decreases the tendency to inhibit. Results provided preliminary support for the theory: Participants higher in personality dominance or assigned control over resources expressed their true attitudes, experienced more positive and less negative emotion, were more likely to perceive rewards (i.e., that their partner liked them), and were less likely to perceive threats (e.g., that their partner felt anger toward them). Most of these effects were mediated by the sense of power, suggesting that subjective feelings of power are an important component in the effects of power.

Perceived organizational support: A review of the literature. 总被引:1,自引:0,他引:1
The authors reviewed more than 70 studies concerning employees' general belief that their work organization values their contribution and cares about their well-being (perceived organizational support; POS). A meta-analysis indicated that 3 major categories of beneficial treatment received by employees (i.e., fairness, supervisor support, and organizational rewards and favorable job conditions) were associated with POS. POS, in turn, was related to outcomes favorable to employees (e.g., job satisfaction, positive mood) and the organization (e.g., affective commitment, performance, and lessened withdrawal behavior). These relationships depended on processes assumed by organizational support theory: employees' belief that the organization's actions were discretionary, feeling of obligation to aid the organization, fulfillment of socioemotional needs, and performance-reward expectancies.

The effect of facially applied air movement on perceived air quality (PAQ) at high humidity was studied. Thirty subjects (21 males and 9 females) participated in three, 3-h experiments performed in a climate chamber. The experimental conditions covered three combinations of relative humidity and local air velocity under a constant air temperature of 26 °C, namely: 70% relative humidity without air movement, 30% relative humidity without air movement and 70% relative humidity with air movement under isothermal conditions. Personalized ventilation was used to supply room air from the front toward the upper part of the body (upper chest, head). The subjects could control the flow rate (velocity) of the supplied air in the vicinity of their bodies. The results indicate an airflow with elevated velocity applied to the face significantly improves the acceptability of the air quality at the room air temperature of 26 °C and relative humidity of 70%. 相似文献

个性化传播包括许多因素:市场营销策略,清晰的数据库,建立客户接触点的数据分析,针对客户接触点的相关市场策略的规则,对客户隐私的保护,文件输出,衡量成功的尺度和响应客户反馈的迭代设计。近年来,利用客户数据实现个性化传播已获得越来越多的关注。然而,利用精确的数学方法从客户数据中提取关系数据,然后将其转化为抽象的规则,并融入实际的设计,这与其说是一种科学技术,不如说是一种艺术。本论文主要探讨了如何有效地将通过数据挖掘得到的重要变量转化为具体的编程规则,以准确地表示这些可变数据,并应用到个性化传播中。 相似文献

The reasons underpinning search biases in 2 species of macaque monkeys (Macaca mulatta and Macaca arctoides) were explored over the course of 3 experiments requiring monkeys to search for a hidden food reward. The results reveal that monkeys are adept at exploiting perceptual cues to locate a food reward but are unable to use physical constraints such as solidity as cues to the reward's location. Monkeys prefer to search for a food reward beneath a solid shelf, not because they have an expectation that the reward should be there, but rather because, in the absence of usable cues, this bias emerges as a default search option. It is hypothesized that this bias may have its roots in a history of competition for food resources. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
