习惯行为、执行意向与青少年身体活动意向与行为:基于计划行为理论的扩展模型

在计划行为理论(TPB)的基础上,引入身体活动习惯行为与执行意向,构建扩展TPB(METPB)模型,检验该模型对9~19岁青少年群体的中高强度身体活动(MVPA)的适用性,探讨该模型对小学、初中及高中阶段青少年MVPA影响的差异。结果显示:假设模型的拟合度可以接受,纳入习惯行为与执行意向后,METPB显著地提高了其对身体活动行为的解释力。态度和感知行为控制对MVPA行为意向有显著性影响,解释了31.4%的行为意向方差;行为意向和习惯行为对MVPA行为有显著性影响,解释了18.7%的行为方差;执行意向加强了行为意向朝实际行为的转换。METPB模型对于不同学习阶段青少年MVPA意向及行为的影响有显著性差异。其中:主观规范对小学生与初中生MVPA意向产生了显著性影响,而对高中生的MVPA意向并无显著性影响;感知行为控制对3个阶段学生的MVPA意向产生的影响随着学习阶段的上升不断增强。建议:在对于青少年身体活动的干预中,政府、家庭、学校应重视培养学生对于身体活动参与的正确态度,提高其参与身体活动的意愿,培养其参与身体活动的行为习惯,且在对青少年身体活动干预时考虑学习阶段的差异。

电子书用户使用意愿影响模型构建与实证

[目的/意义] 探究用户使用电子书意愿的影响因素，以有助于电子书产业走出缓慢的发展困境。[方法/过程] 以UTAUT2、使用满足理论为基础，从需求满足和外部情景因素两个层面构建影响因素模型，并将需求满足细化为内容需求、社交互动需求和休闲娱乐需求3个测量变量。采用问卷调查方法收集有效样本1 013份，使用AMOS21软件对模型进行验证。[结果/结论] 研究发现，需求满足、阅读习惯、价格价值、社会影响对使用意愿有正向影响作用，而激励措施对使用意愿有负向影响作用，努力期望对使用意愿的影响不显著，并依据研究结果提出促进电子书产业发展的建议。     

中国传统体育的审美价值取向与反思

从人对生命追求的角度探讨中国传统体育的审美价值。对人的社会、自然、精神生命的不同追求，构成了儒家、道家、佛教体育审美价值的不同取向。现代体育应以综合开发人的生命意识为发展方向。     

探索式搜寻意图对搜寻策略选择的影响机制研究

[目的/意义]研究旨在回答不同探索式搜寻意图的用户如何表达信息需求,不同的需求表达倾向于采用哪种搜寻策略,以及该选择机制如何受用户预期绩效的影响。[方法/过程]通过理论研究探索用户搜寻意图的复杂性和搜寻策略的多元化,结合用户需求表达和用户预期绩效的分析,建立用户探索式搜寻意图对搜寻策略选择的影响机制的理论研究框架,通过情景模拟问卷获取搜寻行为数据,以揭示无向信息收集、有向信息收集、知识获取、建议咨询、社会联系5种探索式搜寻意图在选择综合搜索引擎、专业搜索引擎、个人空间SMQA、问答平台提问和短视频网站浏览策略时的策略偏好及其成因。[结果/结论]研究表明,探索式搜寻意图需求表达的差异受搜寻目标的性质和用户认知能力的影响;不同需求表达的搜寻策略选择具有显著差异;预期绩效的调节作用促进了探索式搜寻策略选择的多元化和策略转换。

当今图书馆员继续承诺回归方程的构建

本文以多元线性回归为数据分析手段,建立了以当今图书馆员继续承诺为因变量的回归方程模型。该模型的自变量涉及四类,分别是：1、人口学基本信息：馆级领导,进馆5年以内,年龄31-40、51-60,东北地区,研究馆员;2、快乐指数因子：目标价值体验,身体健康体验;3、工作满意度因子：组织氛围满意度,公平满意度;4、快乐程度自评：未来五年与目前的快乐自评。并尝试对这些因子的影响进行了分析     

An integrated model of workload,autonomy, burnout,job satisfaction,and turnover intention among Taiwanese reporters

This study examines the relationships among workload, news autonomy, burnout, job satisfaction, and turnover intention among Taiwanese reporters. Results of a survey of 1,099 reporters indicate that workload and news autonomy were significantly associated with burnout. In addition, burnout was found to be negatively related to job satisfaction, which in turn had a significant effect on turnover intention. The results not only highlight the important role of workload and news autonomy in predicting burnout, but also extend previous research on journalist burnout by showing that job satisfaction acts as a mediator in the relationship between burnout and turnover intention.     

Risk,affect, and policy support: public perception of air pollution in China

Air pollution is a critical environmental problem that has spurred great public concern in China. This study examines how issue salience, environmental value, risk perception, and affective response influence information seeking, objective knowledge, and policy support related to this issue. The recent release of a controversial environmental documentary on Chinese social media, Under the Dome, also prompted us to explore the impact of exposure to this documentary on Chinese social media users’ information seeking and policy support related to air pollution. Results showed that risk perception and negative affect influenced information seeking and policy support both directly and indirectly. Also, exposure to the documentary moderated the effects of key variables on information seeking and policy support. However, contrary to our expectations, no significant relationship was found between information seeking and objective knowledge. Theoretical and practical implications of these findings were discussed.     

The Effect of Web Search Result Display on Users’ Perceptual Experience and Information Seeking Performance

ABSTRACT

Adding multiple sources of information in the display of Web search results may negatively affect users’ perceptual experience and information-seeking behavior. This claim was established by investigating the impact of different Web search compositions on users’ ability to extract specific information. In this article, we assumed that the quantity and order of different compositions (areas) in the Web search results page may contribute to individual’s ability to find information relevant to their search queries. An eye-tracking device was used to observe and compare the perceptual behavior of 14 users in an information-seeking task. The results showed that the use of different compositions in the display of Web results page significantly influenced users’ perceptual experience by reducing their attention to the organic results area. The quantity of these compositions was found to greatly increase the cognitive load of users when attempting to retrieve information from the organic area, which negatively affects their information-seeking performance. Our finding provides a rationale for further studies to consider the impact of quantity and order of Web page compositions on individuals’ perceptual attention and cognitive load in information-seeking task settings.
