Influence analysis is an important component of data analysis, and the local influence approach has been widely applied to many statistical models to identify influential observations and assess minor model perturbations since the pioneering work of Cook (1986) . The approach is often adopted to develop influence analysis procedures for factor analysis models with ranking data. However, as this well‐known approach is based on the observed data likelihood, which involves multidimensional integrals, directly applying it to develop influence analysis procedures for the factor analysis models with ranking data is difficult. To address this difficulty, a Monte Carlo expectation and maximization algorithm (MCEM) is used to obtain the maximum‐likelihood estimate of the model parameters, and measures for influence analysis on the basis of the conditional expectation of the complete data log likelihood at the E‐step of the MCEM algorithm are then obtained. Very little additional computation is needed to compute the influence measures, because it is possible to make use of the by‐products of the estimation procedure. Influence measures that are based on several typical perturbation schemes are discussed in detail, and the proposed method is illustrated with two real examples and an artificial example. 相似文献

采用中国汉字谜,通过模拟wallas(1926)关于顿悟问题解决的四个阶段,探讨了酝酿期有效提示和无效提示对猜字谜的影响。结果发现:有效提示组被试比无效提示组猜对了更多的靶字谜,反应时也更短;在脑电水平上,酝酿期的有效提示谜比无效提示谜在左前额叶分别于300ms-400ms,400ms-600ms,600ms-800ms内引发了更大的P300-400成分、P400-600成分、P600-800成分。表明有效提示谜比无效提示谜对靶字谜问题的解决有更大促进作用。 相似文献

Previous research suggests that there is a relationship between social contexts (e.g., economic growth, engagement in wars) and motives within populations. In particular, high achievement motive is associated with subsequent economic growth, which in turn increases power motive. Increased national achievement and power motives have been argued to precede social changes that lead to decreased affiliation motives, and engagement in wars. The present study aimed to examine differences in achievement, power, and affiliation motives between 266 college students in China (a nation with sustained high economic growth) and 255 college students in the USA (a nation with previously strong but now slowing economic growth, and engaged in war). Analysis of personal strivings suggested that Chinese college students showed significantly higher levels of achievement motive than the American college students, but American college students showed significantly higher levels of affiliation motive than Chinese college students. Overall, males exhibited higher achievement motivation than females. No significant interaction effects were found for gender by location for any of the three motives. The findings are discussed in relation to previous research. 相似文献

目的:探讨话务员成就目标与工作倦怠的关系。方法:采用修订的成就目标量表、工作倦怠量表调查270名移动一线话务员。结果:1.掌握目标取向与负性的情绪耗竭以及玩世不恭存在显著负相关,而与成就动机存在显著正相关;2.表现趋向以及表现回避与情绪耗竭、玩世不恭存在显著正相关,与成就动机存相关系数不显著;3.掌握目标取向负向预测情绪耗竭以及玩世不恭,而正向预测成就动机,而表现回避正向预测情绪耗竭和玩世不恭。结论:掌握目标取向的个体感受的倦怠程度越低,而表现回避和表现趋向的得分越高的个体感受职业倦怠程度越高。 相似文献

明清之际,以天主教为代表的基督教第三次入华,由于伊斯兰教与基督教长期对立的历史背景,再次入华的基督教与中国伊斯兰教的关系颇为复杂,这既表现于基督教对中国伊斯兰教的敌视,也表现于二者在统治机构中的权利争夺,这些对中国伊斯兰教的发展均产生了重要影响。 相似文献

Many studies support the proposition that early cosocialization with opposite-sex children has the effect of inhibiting later mutual sexual attraction, but the existence of a period in the life cycle in which individuals are sensitive to the effect of early cosocialization has been a matter of controversy. Drawing on earlier traditional psychological research, and on more recent work guided by parental investment theory, we hypothesized that only for maternal perinatal association (MPA)-absent males a less-than- around-three-years age difference with the sister can predict stronger aversion to sibling incest. The results corroborated the hypothesis. The results can be interpreted as support for the existence of a sensitive period as well as for the potent role of MPA. Cross-cultural comparative studies were called on to further test the hypothesis. 相似文献
