"Learning myopia: An adaptive recency effect in category learning": Correction to Jones and Sieck (2003).

Reports an error in "Learning myopia: An adaptive recency effect in category learning" by Matt Jones and Winston R. Sieck (Journal of Experimental Psychology: Learning, Memory, and Cognition, 2003[Jul], Vol 29[4], 626-640). On page 633, Table 2, the values in columns (T, P) and (P, T) in the dual condition row incorrectly read .10 and .90, respectively. The correct values are .90 and .10, respectively. (The following abstract of the original article appeared in record 2003-06626-013.) Recency effects (REs) have been well established in memory and probability learning paradigms but have received little attention in category learning research. Extant categorization models predict REs to be unaffected by learning, whereas a functional interpretation of REs, suggested by results in other domains, predicts that people are able to learn sequential dependencies and incorporate this information into their responses. These contrasting predictions were tested in 2 experiments involving a classification task in which outcome sequences were autocorrelated. Experiment 1 showed that reliance on recent outcomes adapts to the structure of the task, in contrast to models' predictions. Experiment 2 provided constraints on how sequential information is learned and suggested possible extensions to current models to account for this learning.

炼制进口原油常减压装置的腐蚀问题

胜利炼油厂第三常减压装置改炼进口高硫原油或进口原油掺炼陆上原油后 ,设备腐蚀明显加重 ,致使换热器E2 4/ 1和空冷器A1/ 1腐蚀率高达 2 .5mm/a。腐蚀加重的主要原因是由于原油脱后盐含量偏高 ( 10～ 2 0mg/L)、硫含量高 ( 1.5 %～ 2 .5 % )所造成的塔顶及其冷凝冷却系统H2 S -HCl-H2 O环境的腐蚀 ,高温重油部位则主要是环烷酸引起的腐蚀。同时提出了改造电脱盐系统、优化原油调配和加强注剂管理等一系列措施
