Human factors and ergonomics research could benefit from focusing more strongly on individual differences – especially trait variables. The present study suggests the analysis of moderator effects as a promising way to enhance understanding of trait variables and process control performance. Process control performance was studied by analysing moderator effects of general mental ability (GMA) and need for cognition (NC) on risky decision-making (RDM) and performance. Fifty engineering students were trained on a process control task using a computer-based simulation for three hours and tested twice thereafter. Risky decision-making was measured using a computerised gambling task while GMA and NC were assessed with questionnaires. Risky decision-making in interaction with each GMA and NC explained variance in performance over and above variance explained by the single effects. In conclusion, the analysis of moderator effects between individual difference variables and process control performance seems promising. Practitioner Summary: Individual difference variables affect learning and performance, but have often not been studied to any great extent in human factors research. This article suggests a promising approach to studying individual differences – moderator analyses – and illustrates how such differences can lead to a better understanding of what determines process control performance. 相似文献

For the blind recognition of Turbo codes in information interception, the recognition algorithm of turbo codes on trellis termination fall into following two parts. In coding structure recognition, turbo codes on trellis termination is defined as linear block codes, so the blind recognition of code length and start is achieved by analyzing the rank of codes matrix with a different number of columns and a different start; In encoder parameter recognition, by comparing the sequence matrix's column vector before and after interleaving and determining the decision threshold, the influence of error codes whose number is lower than the decision threshold is removed, and consequently, the problem of poor fault-tolerant performance in the traditional interleaving mode recognition method is solved. Simulation shows that the correct percentage of recognition is higher than 80% at 10-3 BER, and confirms the validity and reliability of the algorithm. 相似文献

23 highly hypnotizable undergraduates (Harvard Group Scale of Hypnotic Susceptibility) underwent 2 specially constructed 7-item hypnotic inductions. Over the 14 items, the main finding was of a relationship between E. R. Hilgard's (1973, 1977, 1979) "hidden observer" effect and 2 aspects of hypnotic age regression. Ss reporting a hidden observer experienced duality during regression to age 5, in which they were aware of being both adult and child. When asked to write a complex sentence, most did so, usually without spelling errors. The Ss not reporting this effect experienced quasi-lateral age regression in which they had the exclusive feeling of being 5 yrs old, with no sense of an adult identity. Most of these Ss were unable to write the same complex sentence when requested to during age regression. The study replicated Hilgard's finding of the hidden observer phenomenon in terms of its incidence and obtained similar verbal reports from Ss experiencing it. At the same time, the results suggest that a neodissociation account of hypnosis may need some modifications to accommodate these additional findings.

可转债融资与公司股价长期表现实证研究 总被引:1,自引:0,他引:1
实证检验了我国上市公司可转债融资后的股价长期表现,结果发现,可转债融资后的公司股价并未如配股和增发再融资后的长期表现欠佳,而是有一定的优越表现.以EBIT与Size/BM可比公司进行调整后,一年期的累积超过收益分别为13.52%和17.13%,而以大盘指数调整后的一年期累积超额收益仅为0.41%.对以Size/BM可比公司调整后的累积超额收益给予的多元回归分析发现,可转债发行后的一年期股价市场表现与初始转换概率正相关,与股权稀释因子负相关,而在统计意义上不显著,但制造业公司在可转债发行后股价的一年期市场表现优于非制造业的公司,且在10%的水平下显著. 相似文献

The comprehensive transportation project involves with many different transportation methods, such as railway, highway, waterway, airline, and pipeline, which have their special characteristics. To evaluate the transportation project with different transportation methods under the same system, the integrated evaluation method should be built up on the basis of a common index system. This paper suggests a feasible integrated evaluation method including index system establishing, indices transacting, the index weight distributing, and weighted value integrating. 相似文献
