项目反应理论框架下的新等值方法——对数对比等值法   总被引:3,自引:2,他引:1  
项目反应理论有一些以除法形式给出的多级评分模型,若采用Haebara等值法、Stocking_Lord等值法或对称相对熵等值法进行测验等值,都因其对初值有较高要求而可能导致失败。针对这一类模型,我们给出了一种新的等值方法——对数对比等值法。这种方法收敛快,对迭代初值要求低,所得结果精度较高,可以为其他等值方法提供良好的初值。研究表明,对数对比等值法还改进和推广了0-1评分的两参数Logistic模型的Logit变换等值法  相似文献

The paper starts with a presentation of the pure happiness theory, i.e. the idea that the quality of a person’s life is dependent on one thing only, viz. how happy that person is. To find out whether this type of theory is plausible or not, I examine the standard arguments for and against this theory, including Nozick’s experience machine argument. I then investigate how the theory can be modified in order to avoid the most serious objections. I first examine different types of epistemic modifications of the theory (e.g. the idea that a person’s happiness is more valuable for her if it is based on a correct perception of her own life), and then turn to a number of modifications which all make the value of a person’s happiness depend on whether the evaluative standard on which her happiness is based satisfies certain requirements. In connection with this, I present and defend my own modified version of the happiness theory.  相似文献

The current experiment examined whether adjusting-amount and adjusting-delay procedures provide equivalent measures of discounting. Pigeons' discounting on the two procedures was compared using a within-subject yoking technique in which the indifference point (number of pellets or time until reinforcement) obtained with one procedure determined the value of the corresponding variable in the yoked condition with the other procedure. Behavior on each procedure was well described by a hyperbolic discounting function. Results revealed no systematic differences in the degree of discounting as measured by the discounting rate parameter of the hyperbola in Experiment 1, which used 20-mg pellets. These results were replicated in Experiment 2 using smaller, 14-mg pellets, which potentially yield more precise measurement of indifference points on the adjusting-amount procedure. The finding that estimates of the k parameter in the hyperbolic discounting function obtained with one procedure did not differ systematically from estimates obtained from the same subjects with the other procedure represents strong support for the hypothesis that the same process underlies the discounting of delayed rewards on both adjusting-amount and adjusting-delay procedures.  相似文献

Abstract: Philosophy teachers converse with troubled students who suffer from what I dub “intelligent collegiate depression” (ICD): a lack of self‐esteem, feelings of futility and pessimism about their futures, a distrust of academic values, and a lack of conviction that their lives matter. Students express their values and their resignation with what approaches conventional wisdom for them: They must be allowed to act as they wish so long as they do not hurt anyone; otherwise it does not matter what they do with their lives. I argue here that students' endorsement of this near‐nihilistic version of Mill's harm principle shows that they are committed to believing in more values than they realize. I then show how to parlay this commitment into a rejection of the worst effects of ICD—all the while holding in abeyance the question of metaethical objectivism vs. subjectivism. My approach shows that accepting a popular ICD premise logically undermines much of the unhappy ICD worldview.  相似文献

We report six unsuccessful attempts to replicate the "work ethic" phenomenon reported by Clement, Feltus, Kaiser, and Zentall (2000). In Experiments 1-5, pigeons learned two simultaneous discriminations in which the S+ and S- stimuli were obtained by pecking an initial stimulus once or multiple (20 or 40) times. Subsequent preference tests between the S+ stimuli and between the S- stimuli mostly revealed indifference, on average, between the S+ from the multiple-peck (high-effort) trials and the S+ from the one-peck (low-effort) trials, and likewise between the two respective Sstimuli. Using a slightly different procedure that permitted assessment of the relative aversiveness of low versus high effort, Experiment 6 again revealed a pattern of indifference despite showing that pigeons took considerably longer to begin pecking on high- than on low-effort trials. Our findings call into question the reliability of the original findings and the sufficiency of the hypothesized within-trial contrast mechanism to produce them.  相似文献

教师职业价值观是教师对其所从事的教师职业的一种评价,他反映着教师的需要,并直接影响着教师对工作的态度,因此教师职业价值观可以作为学校管理者进行有效管理的一个突破口,认清教师的职业价值观并了解个体差异,通过对教师职业价值观的关注和调动达到有效调动教师的工作积极性。  相似文献

为阐明价值观在集体行动参与中的地位和影响机制,研究者以利比亚事件为背景,针对现实和网络场域中不同程度的4类集体行动倾向,在天津市957名大学生中进行问卷调查研究,结果发现:价值观显著增加了低成本集体行动倾向解释率,并调节着情绪、工具性动机和社会认同对集体行动倾向的影响;中国人进行集体行动决策时具有集体主义理性计算特征;不同场域和程度的集体行动有其各自规律.结论:价值观在集体行动参与决策中是一种与社会认同类似的基础性变量.  相似文献

采用家长式领导行为问卷、运动价值观问卷、运动动机问卷和运动员精神问卷,对495名高校高水平运动员进行调查,以探讨教练家长式领导行为对高校高水平运动员的运动员精神的影响,及其内在的作用机制。结果表明:(1)家长式领导行为对运动员精神有显著的正向影响,运动动机在其中具有部分中介作用;(2)运动价值观在家长式领导行为与运动动机之间具有正向的调节作用,即运动价值观得分越高,这种正向关系也越强;(3)运动价值观对家长式领导行为与运动员精神关系的调节作用,是部分地通过运动动机为中介而产生。  相似文献

In citizen participation, a few representatives of the total citizen population participate in discussions with authorities regarding public decisions and policies. The present study examines a dual process model in which the representatives’ voice and similarity of values facilitate public acceptance through procedural fairness and trust in representatives, respectively. The results of an experiment employing a scenario method, which included participants from Japan (n = 211) and the Netherlands (n = 200), indicate that the representatives’ voice increased procedural fairness and public acceptance when the similarity of representatives was high. The effects of representatives’ voice on public acceptance via procedural fairness was supported in both nations, while other effects of representatives’ similarity on acceptance via trust were indicated only in Japan. These results suggest that the indirect voice of citizens, as conveyed by representatives, plays an important role in increasing perceptions of procedural fairness and public acceptance among citizens.  相似文献
