Multifaceted data are very common in the human sciences. For example, test takers' responses to essay items are marked by raters. If multifaceted data are analyzed with standard facets models, it is assumed there is no interaction between facets. In reality, an interaction between facets can occur, referred to as differential facet functioning. A special case of differential facet functioning is the interaction between ratees and raters, referred to as differential rater functioning (DRF). In existing DRF studies, the group membership of ratees is known, such as gender or ethnicity. However, DRF may occur when the group membership is unknown (latent) and thus has to be estimated from data. To solve this problem, in this study, we developed a new mixture facets model to assess DRF when the group membership is latent and we provided two empirical examples to demonstrate its applications. A series of simulations were also conducted to evaluate the performance of the new model in the DRF assessment in the Bayesian framework. Results supported the use of the mixture facets model because all parameters were recovered fairly well, and the more data there were, the better the parameter recovery. 相似文献

Although men typically hold favorable views of advertisements featuring female sexuality, from a Terror Management Theory perspective, this should be less the case when thoughts of human mortality are salient. Two experiments conducted in South Korea supported this hypothesis across a variety of products (e.g., perfume and vodka). Men became more negative towards advertisements featuring female sexuality, and had reduced purchase intentions for those products, after thinking about their own mortality. Study 2 found that these effects were mediated by heightened disgust. Mortality thoughts did not impact women in either study. These findings uniquely demonstrate that thoughts of death interact with female sex-appeal to influence men’s consumer choices, and that disgust mediates these processes. Implications for the role of emotion, and cultural differences, in terror management, for attitudes toward female sexuality, and for marketing strategies are discussed. 相似文献

This study draws on costly signaling theory (CST) and explores the hidden motive of proactive knowledge sharing. We theorize that the need for status drives employees to generously share their tacit knowledge and special expertise to obtain social recognition and status as conferred by supervisory appraisal. We tested our hypotheses based on the moderated mediation model using a sample of 146 supervisor–subordinate dyads that were collected from South Korean organizations. The present analysis supports the proposed theoretical framework based on CST, thereby providing new insights into the need for status as an unexplored hidden motive of proactive knowledge sharing and the roles of job design factors as contextual contingencies. This study offers theoretical and practical implications related to knowledge management, employee motivation, and job design. 相似文献

By atomic-scale high-angle annular dark-field scanning transmission electron microscopy, the long-period stacking ordered (LPSO) structures in a near-equilibrium Mg97Zn1Y2 (at.%) alloy have been characterised. In addition to 18R and 14H, new polytypes of LPSO structures are analysed and determined as 60R, 78R, 26H, 96R, 38H, 40H, 108H and 246R. All of these LPSO structures feature AB′C′A building blocks with two Mg layers and three Mg layers sandwiched between them. The Bravais lattices and space groups of new polytypes of LPSO structures were easily determined via the newly introduced method. A structural relationship between the LPSOs is proposed. 相似文献

目的:以中国传统的财富观和刻板印象内容模型为理论基础,采用实验法,探讨道德、热情和能力在贫富心理融合中的作用。方法:613名社会人士参加了实验,两个实验分别操作了穷人和富人身份。结果:无论对穷人还是富人的心理融合,道德、热情和能力三个因素对心理融合的主效应都显著,且道德因素的效应值最大。这表明,人们对贫富群体的心理融合存在"道德突显效应",即道德因素在人们对穷人和富人的心理融合过程中起到重要作用。 相似文献

The relative preference for a target product over a competitor can be increased by providing a third alternative (a “decoy”) that is clearly inferior to the target but is not necessarily inferior to the competitor. In 3 experiments, we examined the conditions in which these decoy effects occur. When participants reported their preferences immediately after being exposed to the information about them, the influence of decoys on preferences was attributable to the justification they provided for choosing the target over the competitor. (That is, a decoy had an impact if and only if the target was superior to the decoy but the competitor was not.) When participants evaluated each product individually before making their choices, however, they based their preferences on these evaluations. In this case, decoys exerted their influence through their impact on the values that participants assigned to the attributes on which the evaluations were based. This influence was evident even when the decoy was clearly inferior to both the target and competitor. Moreover, it occurred under conditions in which the target and competitor were in different product categories and also when the decoy was in a totally different product domain than the target and competitor. 相似文献

Contributions of processing ability and knowledge to verbal memory tasks across the adult life-span 总被引:3,自引:0,他引:3

This study investigated the relationships of processing capacity and knowledge to memory measures that varied in retrieval difficulty and reliance on verbal knowledge in an adult life-span sample (N = 341). It was hypothesized that processing ability (speed and working memory) would have the strongest relationship to tasks requiring active retrieval and that knowledge (vocabulary ability) would be related to verbal fluency and cued recall, as participants relied upon verbal knowledge to retrieve category items (fluency) or develop associations (cued recall). Measurement and structural equation models were developed for the entire sample and separately for younger (aged 20-54 years, n = 168) and older (aged 55-92 years, n = 173) subgroups. In accordance with the hypotheses, processing ability was found to be most highly related to free recall, with additional significant relationships to cued recall, verbal fluency, and recognition. Knowledge was found to be significantly related only to verbal fluency and to cued recall. Moreover, knowledge was more important for older than for younger adults in mediating variance in cued recall, suggesting that older adults may use age-related increases in knowledge to partially compensate for processing declines when environmental support is available in memory tasks. 相似文献
