轻工企业组织行为与经济绩效的实证研究

为了探索中国轻工企业组织行为与经济绩效的因果关系和操作模式,我们参考英、荷、日三国有关企业组织行为的态度量表,设计了一套涵盖企业对市场竞争、文化理念和管理情景的“三模块”总量表,在轻工行业抽取八个样本企业,实施现场实验,采集有关企业组织行为的态度指数,然后与其经济绩效进行关联分析．结果表明,轻工企业组织行为的态度指数与其经济绩效总体趋势呈正相关,但个案分析提示两者间关系复杂,不仅有正相关,也有负相关现象;究其规律尚须扩大样本行纵贯式追踪研究．     

Measures of response bias at minimum-detectable luminance levels in the pigeon

Using an operant analogue of the yes-no detection task, six pigeons were trained to detect luminance changes under two different reinforcement-scheduling procedures. In the first, an uncontrolled reinforcement-ratio procedure, the relative frequency of food reinforcers obtained for correct detections was free to vary with the birds' behavior as luminance levels were changed. In the second, a controlled reinforcement-ratio procedure, changes in preference could not alter the relative distribution of food reinforcers between the two response alternatives. Extreme response biases developed as luminance was decreased to threshold in the uncontrolled procedure. No progressive changes in response bias as a function of decreasing luminance were seen in the controlled procedure. Absolute thresholds for light intensity were lower in the controlled than in the uncontrolled procedure.     

The temporal organization of behavior on periodic food schedules.

Various theories of temporal control and schedule induction imply that periodic schedules temporally modulate an organism's motivational states within interreinforcement intervals. This speculation has been fueled by frequently observed multimodal activity distributions created by averaging across interreinforcement intervals. We tested this hypothesis by manipulating the cost associated with schedule-induced activities and the availability of other activities to determine the degree to which (a) the temporal distributions of activities within the interreinforcement interval are fixed or can be temporally displaced, (b) rats can reallocate activities across different interreinforcement intervals, and (c) noninduced activities can substitute for schedule-induced activities. Obtained multimodal activity distributions created by averaging across interreinforcement intervals were not representative of the transitions occurring within individual intervals, so the averaged multimodal distributions should not be assumed to represent changes in the subject's motivational states within the interval. Rather, the multimodal distributions often result from averaging across interreinforcement intervals in which only a single activity occurs. A direct influence of the periodic schedule on the motivational states implies that drinking and running should occur at different periods within the interval, but in three experiments the starting times of drinking and running within interreinforcement intervals were equal. Thus, the sequential pattern of drinking and running on periodic schedules does not result from temporal modulation of motivational states within interreinforcement intervals.     

Experience and self-consciousness

Does all conscious experience essentially involve self-consciousness? In his Subjectivity and Selfhood: Investigating the First-Person, Dan Zahavi answers “yes”. I criticize three core arguments offered in support of this answer—a well-known regress argument, what I call the “interview argument,” and a phenomenological argument. Drawing on Sartre, I introduce a phenomenological contrast between plain experience and self-conscious experience. The contrast challenges the thesis that conscious experience entails self-consciousness.
