Pigeons were trained on a multiple schedule in which separate concurrent schedules were presented in the two components of the schedule. During one component, concurrent variable-interval 40-sec variableinterval 80-sec schedules operated. In the second component, concurrent variable-interval 40-sec variableinterval 20-sec schedules operated. After stable baseline performance was obtained in both components, extinction probe choice tests were presented to assess preference between the variable-interval 40-sec schedules from the two components. The variable-interval 40-sec schedule paired with the variableinterval 80-sec schedule was preferred over the variable-interval 40-sec schedule paired with the variableinterval 20-sec schedule. The subjects were also exposed to several resistance-to-change manipulations: (1) prefeeding prior to the experimental session, (2) a free-food schedule added to timeout periods separating components, and (3) extinction. The results indicated that preference and resistance to change do not necessarily covary. 相似文献

回想起来,"忍者追捕"涉及的是一个席卷斯塔顿岛的连环"忍者盗贼"。"武当乐队"正是发祥此地且名声在外,出于对功夫电影的敬意,在很久以前他们把这个地方戏称为"少林"。这个特别的盗贼,如今已被认定在过去的七个月里洗劫了十八户人家。九月,他在东安山的基奥洛家作案时,遇到了当地居民菲儿·基奥洛,"忍者盗贼"之恶名便是源自此案。他一身黑衣,戴着黑色面具,基奥洛说道,那盗贼还拿着双节棍。他用那副双节棍击打基奥洛的 相似文献

This study examined technical and nontechnical employee attitudes toward participation in training. A survey was administered to 337 self‐identified technical and nontechnical university employees. Our findings are as follows: (a) most employees prefer training that is less than 2 hours in length, (b) employees do not want training outside their regular shift, (c) employees strongly prefer hands‐on training, and (d) less than half were encouraged by their supervisor to apply what was learned in nontechnical training to their job. 相似文献

司法公正现实化经历了一个从告知真理到发现真理的演进过程 ,其目标从实体公正与程序公正的统一、分化到并重 ;其模式由国家职权主义与当事人主义各自独立发展到二战以来的相互渗透。西方司法公正现实化源于人民对公正理念的执着追求和法官精英队伍的形成 相似文献

This paper considers the development of school students’ ability to define three terms that are fundamental to statistical
literacy: sample, random, and variation. A total of 738 students in grades 3, 5, 7, and 9 were asked in a survey to define
and give an example for the word “sample.” Of these, 379 students in grades 7 and 9 were also asked about the words “random”
and “variation.” Responses were used to describe developmental levels overall and to document differences across grades on
the understanding of these terms. Changes in performance were also monitored after lessons on chance and data, emphasizing
variation for 335 students. After 2 years, 132 of these students and a further 209 students who were surveyed originally but
did not take part in specialized lessons, were surveyed again. The difference after 2 years between the performance of students
who experienced the specialized lessons and those who did not was considered, revealing no differences in performance longitudinally.
For students in grades 7 and 9, the association of performance on the three terms was explored. Implications for mathematics
and literacy educators are discussed. 相似文献

Several tasks used in research studies are presented with assessment rubrics and examples of the development of student understanding. The tasks focus on students’ appreciation of variation in several contexts and illustrate the need to discuss variation in the classroom and to ask students specifically about it during assessment. 相似文献
