This study examined the association of scores on measures of traditionality and gratitude. Briefly defined, traditionality refers to how strongly one endorses the traditional value of submission to authority for harmony and benefits in a collective group. Traditional Taiwanese culture is linked with collectivism, and the society tends to encourage members to respect authority and harmony. As people of a collectivistic view seek to maintain harmony within the group, gratitude and reciprocity of good is expected from members. Nevertheless, traditionality of values differs among group members, as is also true for gratitude. It is not known how scores on traditionality might relate to feelings of gratitude among athletes in the competitive sports setting. 289 Taiwanese high school athletes were administered the Sport-domain Gratitude Questionnaire by Chen and Kee and the Traditionality Scale by Kao and Lu. Data, subjected to structural equation modeling, show that traditionality scores were related to those on gratitude. Implications and limitations were discussed. 相似文献
The purpose of this study is to find a formula that describes the relationship between item exposure parameters and item parameters in computerized adaptive tests by using genetic programming (GP) – a biologically inspired artificial intelligence technique. Based on the formula, item exposure parameters for new parallel item pools can be predicted without conducting additional iterative simulations. Results show that an interesting formula between item exposure parameters and item parameters in a pool can be found by using GP. The item exposure parameters predicted based on the found formula were close to those observed from the Sympson and Hetter (1985) procedure and performed well in controlling item exposure rates. Similar results were observed for the Stocking and Lewis (1998) multinomial model for item selection and the Sympson and Hetter procedure with content balancing. The proposed GP approach has provided a knowledge‐based solution for finding item exposure parameters. 相似文献
This paper proposes an on‐line version of the Sympson and Hetter procedure with test overlap control (SHT) that can provide item exposure control at both the item and test levels on the fly without iterative simulations. The on‐line procedure is similar to the SHT procedure in that exposure parameters are used for simultaneous control of item exposure rates and test overlap rate. The exposure parameters for the on‐line procedure, however, are updated sequentially on the fly, rather than through iterative simulations conducted prior to operational computerized adaptive tests (CATs). Unlike the SHT procedure, the on‐line version can control item exposure rate and test overlap rate without time‐consuming iterative simulations even when item pools or examinee populations have been changed. Moreover, the on‐line procedure was found to perform better than the SHT procedure in controlling item exposure and test overlap for examinees who take tests earlier. Compared with two other on‐line alternatives, this proposed on‐line method provided the best all‐around test security control. Thus, it would be an efficient procedure for controlling item exposure and test overlap in CATs. 相似文献
This research examined how the presentation of items related to goals and temptations influences the dynamic of self-regulation, as reflected in evaluation and choice. The authors found that when items, such as healthy and unhealthy foods or academic and leisure activities, are presented together in a unified choice set (e.g., in 1 image) and seem to complement each other, people express a positive evaluation of and a preference for tempting items. Conversely, when the items are presented apart from each other in 2 choice sets (e.g., 2 images) and seem to compete with each other, people express a positive evaluation of and preference for goal items. 相似文献
Anxiety disorders are the most common type of psychiatric conditions in children. Early identification and intervention during preschool years is critical for minimizing their detrimental long-term effects. The Preschool Anxiety Scale (PAS) is a developmentally-sensitive and symptom-specific instrument that has been commonly used and widely validated in the west. The current study tested the psychometric properties of its Traditional Chinese version (PAS-TC) in Hong Kong. The study sample consisted of a total of 1317 Hong Kong parents, recruited from 12 local preschools, with preschool children aged from three to six years old. Results showed that a correlated five-factor model demonstrated a good fit for the data. PAS-TC also demonstrated acceptable reliability and satisfactory validity. Furthermore, gender but not age effects were found in Hong Kong. Additionally, similar to previous studies, items from physical injury fears were the most reported in the top-ten frequently endorsed items. Finally, the anxiety level of our Hong Kong sample was found to be between the Mainland China and western countries. Clinical implications of the above findings concerning PAS-TC are discussed.
Traditional mediation analysis assumes that a study population is homogeneous and the mediation effect is constant over time, which may not hold in some applications. Motivated by smoking cessation data, we propose a latent class dynamic mediation model that explicitly accounts for the fact that the study population may consist of different subgroups and the mediation effect may vary over time. We use a proportional odds model to accommodate the subject heterogeneities and identify latent subgroups. Conditional on the subgroups, we employ a Bayesian hierarchical nonparametric time-varying coefficient model to capture the time-varying mediation process, while allowing each subgroup to have its individual dynamic mediation process. A simulation study shows that the proposed method has good performance in estimating the mediation effect. We illustrate the proposed methodology by applying it to analyze smoking cessation data.
Relative to previous research concerning the positive association between high-performance work systems (HPWS) and employees’ voice and helping, we examined a wider range of mediators reflecting employees’ ability, motivation, and opportunity to expand their citizenship-based role definitions. Trust in the supervisor was also investigated as a boundary condition on the relationships in question. Multisource data, collected in 4 waves, from 208 supervisor–employee dyads showed that employees’ efficacy, instrumentality, and autonomy perceptions concerning voice mediated the association between employee-experienced HPWS and expanded role definition for voice. Instrumentality mediated the relationship between employee-experienced HPWS and expanded role definition for helping. The positive links between employee-experienced HPWS and both supervisor-rated helping and voice were mediated by employees’ role definitions. Trust in the supervisor positively moderated the mediated effects. 相似文献
