Generalized full-information item bifactor analysis

Full-information item bifactor analysis is an important statistical method in psychological and educational measurement. Current methods are limited to single-group analysis and inflexible in the types of item response models supported. We propose a flexible multiple-group item bifactor analysis framework that supports a variety of multidimensional item response theory models for an arbitrary mixing of dichotomous, ordinal, and nominal items. The extended item bifactor model also enables the estimation of latent variable means and variances when data from more than 1 group are present. Generalized user-defined parameter restrictions are permitted within or across groups. We derive an efficient full-information maximum marginal likelihood estimator. Our estimation method achieves substantial computational savings by extending Gibbons and Hedeker's (1992) bifactor dimension reduction method so that the optimization of the marginal log-likelihood requires only 2-dimensional integration regardless of the dimensionality of the latent variables. We use simulation studies to demonstrate the flexibility and accuracy of the proposed methods. We apply the model to study cross-country differences, including differential item functioning, using data from a large international education survey on mathematics literacy.     

认同理论视角下新员工组织社会化的定义及结构维度

组织社会化研究一直以来被批评缺少理论基础, 导致对组织社会化的本质和结构维度缺乏足够认识, 从而影响到在实证中如何测量员工组织社会化的程度。角色认同理论和社会认同理论可以为该研究提供理论基础。在对概念重新进行理论界定的基础上, 揭示了组织社会化本质是新员工角色及社会认同发展的过程。相应地, 组织社会化程度是一个两维度结构。未来研究应以此为基础进一步发展组织社会化量表和理论模型, 并依据认同理论改进实证研究方法。     

程序公正的测量及研究操纵

程序公正是指处理管理事务所依据的原则是否公正。普遍认可的程序公正原则包括一致性、避免偏见、准确性、可修正、代表性、道德与伦理原则。程序公正研究主要有测量和实验操纵两种研究范式。对程序公正的测量主要以单维为主,亦有少数多维测量量表;对程序公正的实验操纵主要以发言权为主,有少数研究对准确性、无偏性或综合几项原则进行操纵。未来研究应考虑程序公正的结构问题,对程序公正的操纵范围进行扩展、操纵方法考虑情景性,还需关注程序公正与程序不公正的差异。     

Cross-modal personality attributions in synaesthetes and non-synaesthetes

Those variants of synaesthesia that trigger colour are well studied, although comparatively less is known about variants that involve cognitive constructs such as personality types. Here we investigate sequence-personality synaesthesia (also known as ordinal linguistic personification, OLP) in which sequenced units (e.g., letters) become associated to personalities or genders. We present the first group study of this variant, showing similarities and differences between synaesthetes and non-synaesthetes. In Experiment 1, we show that synaesthetes differ from the general population in the phenomenology of their reports, the depth of their personality associations, and the consistency of those associations over time. In Experiment 2, we show that synaesthetes are similar to the general population in the underlying rules that link their personalities to letters. Specifically, we show that these mappings are not random, but are based on a shared rule system linking linguistic qualities of letters with quantitative dimensions of personality (based on Goldberg's Big Five personality traits; Goldberg, 1990, 1992). Synaesthetes tend to associate high-frequency letters with high agreeable and low neurotic personalities, and non-synaesthetes share these tendencies at an implicit level. Together, these data show that synaesthetes differ from the general population in phenomenological ways, but that their underlying mechanisms may be common to all people.     

The closer the relationship, the more the interaction on facebook? Investigating the case of Taiwan users

This study argues for the necessity of applying offline contexts to social networking site research and the importance of distinguishing the relationship types of users' counterparts when studying Facebook users' behaviors. In an attempt to examine the relationship among users' behaviors, their counterparts' relationship types, and the users' perceived acquaintanceships after using Facebook, this study first investigated users' frequently used tools when interacting with different types of friends. Users tended to use less time- and effort-consuming and less privacy-concerned tools with newly acquired friends. This study further examined users' behaviors in terms of their closeness and intimacy and their perceived acquaintanceships toward four different types of friends. The study found that users gained more perceived acquaintanceships from less close friends with whom users have more frequent interaction but less intimate behaviors. As for closer friends, users tended to use more intimate activities to interact with them. However, these activities did not necessarily occur more frequently than the activities they employed with their less close friends. It was found that perceived acquaintanceships with closer friends were significantly lower than those with less close friends. This implies that Facebook is a mechanism for new friends, rather than close friends, to become more acquainted.     

Is playing exergames really exercising? A meta-analysis of energy expenditure in active video games

This article reports a meta-analysis of energy expenditure (EE) of playing active video games (AVGs). In particular, heart rate (HR), oxygen consumption (VO2), and EE were assessed and three moderators for the effects of AVGs--types of AVG, player age, and player weight status--were analyzed. The results show that playing AVGs significantly increased HR, VO2, and EE from resting. The effect sizes of playing AVGs on HR, VO2, and EE were similar to traditional physical activities. AVG type and player age were significant moderators for the effects of AVGs. The finding suggests that AVGs are effective technologies that may facilitate light- to moderate-intensity physical activity promotion.     

First person plural: Roman Jakobson’s grammatical fictions

Roman Jakobson, who had left Russia in 1920 and in 1941 took refuge in the USA from the Nazis, was one of the main figures in post war linguistics and structuralism. Two aspects of his work are examined in this article. Firstly, Jakobson purifies his linguistic theory of pragmatic references. Secondly, he develops his own diplomatic mission of mediating between East and West. In this article, I argue that these two aspects did not develop independently from one another. Instead I claim that his theory is designed to slip through the Iron Curtain, while at the same time providing the means to analyse ways of acting politically by using language. This argument is unfolded in two steps, each consisting of two parts. First, I compare the theory of pronominal expressions as developed by Emil Benveniste to Jakobson’s theory of shifters. While Benveniste focuses on the relation of language and its subject using language, Jakobson introduces a model of communication to allow maximal formalisation of language. According to this even the category of person can be freed from its reference to a subject which would be understood as having a place in space and time. Then, Jakobson’s theory of shifters is studied in relation to his analyses of poetry. For this, two examples are chosen: Jakobson’s text on two poems by Russian poet Alexandr Blok, and his text on a poem by Bertold Brecht. In both texts, the theory of shifters—and the alleged purification from pragmatic aspects of language use ensuing from this theory—is challenged by the simple fact that they focus on the pronoun of the first person plural. According to Jakobson, the category of number does not belong to the shifters. Rather, number quantifies participants of the related event. The pronoun ‘we’ is at the same time a shifter and a non-shifter, as it refers to the speech event and the related event. Thus the pronoun ‘we’ opens up the possibility to include or exclude the participants of a communicative situation, and thereby enables the speaker to act socially or even politically by using language. The article concludes by coming back to the historical situation in which Jakobson developed his analyses of poetry. Analysing poetry seems to have been a passe-partout for him, a seemingly harmless subject that allowed him to get a foot in the door of remote and secluded lecture halls.     

黄老学派“类法治”思想探析

黄老思想是战国时期兴起的一个哲学政治思想,一方面其强调"道生法",主张法律的道德基础、强调法律的权威与作用;另一方面主张"循法而治",并提出君主"无为而治",弱化统治者的主观能动性,防止统治者对法律的侵害。相对于中国古代的法家、儒家等其它学派法律思想,其法律思想更接近于西方的法治思想,对我国今天的法治建设有一定的现实借鉴意义。     

Learning HMM-based cognitive load models for supporting human-agent teamwork

Cognitive studies indicate that members of a high performing team often develop shared mental models to predict others’ needs and coordinate their behaviors. The concept of shared mental models is especially useful in the study of human-centered collaborative systems that require humans to team with autonomous agents in complex activities. We take the position that in a mixed human-agent team, agents empowered with cognitive load models of human team members can help humans develop better shared mental models to enhance team performance. Inspired by human information processing system, we here propose a HMM-based load model for members of human-agent teams, and investigate the development of realistic cognitive load models. A cognitive experiment was conducted in team contexts to collect data about the observable secondary task performance of human participants. The data were used to train hidden Markov models (HMM) with varied numbers of hypothetical hidden states. The result indicates that the model spaces have a three-layer structure. Statistical analysis also reveals some characteristics of the models at the top-layer. This study can be used in guiding the selection of HMM-based cognitive load models for agents in human-centered multi-agent systems.
