A Person Fit Test For Irt Models For Polytomous Items

A person fit test based on the Lagrange multiplier test is presented for three item response theory models for polytomous items: the generalized partial credit model, the sequential model, and the graded response model. The test can also be used in the framework of multidimensional ability parameters. It is shown that the Lagrange multiplier statistic can take both the effects of estimation of the item parameters and the estimation of the person parameters into account. The Lagrange multiplier statistic has an asymptotic χ²-distribution. The Type I error rate and power are investigated using simulation studies. Results show that test statistics that ignore the effects of estimation of the persons’ ability parameters have decreased Type I error rates and power. Incorporating a correction to account for the effects of the estimation of the persons’ ability parameters results in acceptable Type I error rates and power characteristics; incorporating a correction for the estimation of the item parameters has very little additional effect. It is investigated to what extent the three models give comparable results, both in the simulation studies and in an example using data from the NEO Personality Inventory-Revised.     

An experimental study about the congruence between type A behavior pattern and type of task

This paper is an experimental study, the basic aim of which is to check whether the congruence between personality characteristics and task characteristics has positive effects for performance and satisfaction on individuals. The results obtained reveal that Type A behavior pattern individuals get better results in cases of congruence than in cases of incongruence, while the performance of Type B behavior pattern individuals is not related to the (in)congruence between personal needs/aims and the task's demands. Besides, we have found that Type A behavior pattern individuals also have greater levels of satisfaction in cases of congruence than in cases of incongruence. However, Type B behavior pattern individuals show the same levels of satisfaction in both cases.     

结合选择题与主观题信息的两阶段作弊甄别方法

为提高对高分作弊者和低抄袭比例作弊者的检验力,模拟600名考生的作答,设置3种抄袭比例（60%,80%和100%）和3种抄袭源能力（能力百分等级为60%,80%和100%）,设计两阶段作弊甄别法,第一阶段使用lz指数筛选个人拟合差的异常考生,第二阶段针对这些异常考生使用ω指数进行精确甄别。结果表明该法对高分作弊者和低抄袭比例作弊者的检验力优于仅使用答案抄袭检测法。     

成为自己的掌舵者：个体自我领导的多层次驱动机制

在信息化、数字化、智能化的新经济背景下,自我领导对组织和个人都有更为积极的价值。然而,已有的自我领导概念与研究局限于控制理论,实证考察多限于单一层次,且未能充分揭示自我领导的驱动机制。首先拓展自我领导的概念内涵,并开发新的测量工具。在此基础上,分别构建个体自我领导的跨层次驱动机制和多层次垂滴模型,并尝试探究个体特征、领导因素、组织情境因素和工作特征等对于个体自我领导的影响。由此,有望为自我领导提供更为丰富、准确、更新的内涵与测量,深化个体自我领导形成的驱动机制及边界条件,也有助于组织实践中有效激发自我领导。     

Valuing time: Moderate download times can improve online goal pursuit

This research examines how the length of time for which a goal is interrupted affects goal pursuit, in an online context. Goal interruption duration in the form of long download time duration has been identified as a significant impediment to electronic commerce. It is believed that a faster download time is always better to motivate web users to keep surfing. We challenge this belief. In three studies, we find that, under certain circumstances, longer rather than shorter download times motivate web users to keep surfing longer. The counterintuitive pattern of effects can be explained by web users' fit experiences (Higgins, 2000) while surfing. In particular, our findings suggest that when online surfing “feels right”, web users think that online information is right.     

Regulatory fit from attribute‐based versus alternative‐based processing in decision making

This paper discusses the fit between attribute-based versus alternative-based processing and regulatory focus, and its impact on decision outcome valuation. Attribute-based processing was found to occur more frequently under prevention focus, whereas alternative-based processing occurred more frequently under promotion focus. The fit between prevention/promotion focus and attribute-based/alternative-based processing was found to enhance satisfaction with choices and the perceived monetary value of chosen options. Moreover, the effect of fit on outcome valuation was found to be mediated by ease of processing. Finally, the effects of fit on ease of processing and outcome valuation disappeared when consumers first practiced to process information based on either attributes or alternatives.     

Family and Neighborhood Fit or Misfit and the Adaptation of Mexican Americans

In this study, a person-environment fit model was used to understand the independent and combined roles of family and neighborhood characteristics on the adjustment of adults and children in a sample of 750 Mexican American families. Latent class analysis was used to identify six qualitatively distinct family types and three quantitatively distinct neighborhood types using socioeconomic and cultural indicators at each level. The results showed that members of single-parent Mexican American families may be particularly at-risk, members of the lowest-income immigrant families reported fewer adaptation problems if they lived in low-income neighborhoods dominated by immigrants, members of economically successful immigrant families may be more at-risk in integrated middle class neighborhoods than in low-income neighborhoods dominated by immigrants, and members of two-parent immigrant families appear to be rather resilient in most settings despite their low socioeconomic status.     

人-职务匹配、人-组织匹配对员工工作态度的效应机制研究

本研究采用结构方程建模方法检验了人与职务、组织匹配对员工工作满意感和组织承诺的效应,及“内部整合”与“人际预测”的中介作用。结果表明,人与职务、组织匹配对员工工作满意感和组织承诺有显著的积极效应,“内部整合”对这种效应起完全中介作用,而“人际预测”仅对“人-职务匹配”对员工工作满意感的效应起部分中介作用。研究为理解“人-环境匹配”对于员工工作态度的效应机制提供了理论框架和实证依据。     

The Development of Early Attachment Behaviours

The normative development of attachment behaviours and the changing relationship between the level of activation of the attachment system and the intensity of subsequent attachment behaviours were studied longitudinally from 3 to 12 months of age. The study was based on Bowlby's notion about increasing goal directedness of the attachment system. The sample consisted of two groups of children, 33 children born with cleft lip and palate and 34 children without this congenital anomaly. To circumvent the age-limited applicability of the Strange Situation procedure, a new observational instrument was developed, the so-called Induced Stress at Home procedure. It appeared that the ISH procedure is a valid alternative to induce and measure the attachment behaviours proximity seeking, contact maintenance and avoidance. Using the multilevel model for longitudinal data, it was shown that attachment behaviours are not very stable across age. An elaborated model revealed that the relationship between activation of the attachment system and subsequent contact maintenance and resistant behaviour become less strong with age. No differences between children with and without cleft lip and palate were found.     

自陈量表式测验应用IRT的可行性

对采用5级评分Likert式测题的情感能力量表的分析表明,各分量表项目都有较好的模型-数据拟合性,而且显示了参数估计的不变性,及与CTT参数的关联性。这些都表明Likert量表应用IRT模型的假设条件得到了满足,即IRT应用是可行的。研究还表明IRT能对测量精度进行更精确的估计。
