Extending the 3 × 2 achievement goal model to the sport domain: The 3 × 2 Achievement Goal Questionnaire for Sport

In the present research, we sought to extend the 3 × 2 achievement goal model recently proffered in the school domain to the sport domain. We did so by conducting two studies focused on the development and initial validation of the 3 × 2 Achievement Goal Questionnaire for Sport (3 × 2 AGQ-S). Study 1 (n = 679), devised items for the questionnaire and demonstrated that data from the questionnaire nicely fit the proposed 3 × 2 model, showed a better fit to the 3 × 2 model than to alternative models, and indicated that each goal variable had good internal consistency. Study 2 again documented the strong psychometric properties of the measure, and additionally linked the goal variables to other constructs central to the achievement goal literature. The establishment of this measure allows extensive study of the 3 × 2 achievement goal model in the sport domain, and promises to yield deeper insights into the nature of achievement motivation in such contexts.     

A general proof of consistency of heuristic classification for cognitive diagnosis models

The Asymptotic Classification Theory of Cognitive Diagnosis (Chiu et al., 2009, Psychometrika, 74, 633–665) determined the conditions that cognitive diagnosis models must satisfy so that the correct assignment of examinees to proficiency classes is guaranteed when non‐parametric classification methods are used. These conditions have only been proven for the Deterministic Input Noisy Output AND gate model. For other cognitive diagnosis models, no theoretical legitimization exists for using non‐parametric classification techniques for assigning examinees to proficiency classes. The specific statistical properties of different cognitive diagnosis models require tailored proofs of the conditions of the Asymptotic Classification Theory of Cognitive Diagnosis for each individual model – a tedious undertaking in light of the numerous models presented in the literature. In this paper a different way is presented to address this task. The unified mathematical framework of general cognitive diagnosis models is used as a theoretical basis for a general proof that under mild regularity conditions any cognitive diagnosis model is covered by the Asymptotic Classification Theory of Cognitive Diagnosis.     

混沌理论对优化临床管理模式的启示——以孕产妇管理为例

围绕混沌理论与妊娠及分娩之间的联系,结合实践,提出可行的优化孕产妇管理工作的建议。强调医务人员应应用线上及线下多种方式,于孕前、孕期、产时、产后各阶段,针对孕产妇身心各方面,对其实施系统化的管理;应重点把握与孕妇首次接触的时机,建立信任关系以保证其良好的遵医行为;管理过程中应尊重孕产妇的个体差异,为其提供个性化的指导,同时应重视其支持系统的建立,医疗机构、社区、家庭应为孕产妇提供切实的支持。旨在为孕产期保健工作提供新思路,从而更好地为广大孕产妇服务。     

科学发展观与生态医学模式

分析了生物医学模式没有转型为生物心理社会医学模式的原因。认为生态危机背景下的医学发展模式研究,应把提高人的生命质量和改善人的生存、生活环境等相关条件,纳入视野之中,这正表现出生态医学模式的价值基础与科学发展观在根本上的一致性。以生态医学模式引领未来医学发展是实践科学发展观的必然要求和具体行动。

Diagnostic Classification Models for a Mixture of Ordered and Non-ordered Response Options in Rating Scales

When developing ordinal rating scales, we may include potentially unordered response options such as “Neither Agree nor Disagree,” “Neutral,” “Don’t Know,” “No Opinion,” or “Hard to Say.” To handle responses to a mixture of ordered and unordered options, Huggins-Manley et al. (2018) proposed a class of semi-ordered models under the unidimensional item response theory framework. This study extends the concept of semi-ordered models into the area of diagnostic classification models. Specifically, we propose a flexible framework of semi-ordered DCMs that accommodates most earlier DCMs and allows for analyzing the relationship between those potentially unordered responses and the measured traits. Results from an operational study and two simulation studies show that the proposed framework can incorporate both ordered and non-ordered responses into the estimation of the latent traits and thus provide useful information about both the items and the respondents.     

回避与趋近性负性人格特质对应激心血管反应模式的不同影响

本研究考察了回避与趋近性负性特质对不同强度心理社会应激刺激重复暴露的心血管反应、应激后心血管反应恢复、重复应激心血管反应的影响,并探讨了应激认知评价在其中的作用。167名大学生被试被随机分配到中/高强度应激条件中,连续采集其在基线期、首次应激期、恢复期、重复应激期四个阶段的心血管反应数据。结果发现:(1)无论应激强度如何,回避性负性特质预测首次和重复应激中较低(钝化)的心血管反应和应激后较差的恢复,而趋近性负性特质预测较大的心血管反应和应激后较差的恢复。(2)重复应激个人资源感知在回避性负性特质与重复应激心率反应之间起中介作用。因此,回避性负性特质与持续较低(钝化)的应激心血管反应和应激后较差的恢复相联系,而趋近性负性特质与较大的应激心血管反应和应激后较差的恢复相联系,即两类负性特质均表现出不适应的固化的应激心血管反应模式,这可能构成了两类不同负性特质增加罹患心血管疾病风险的生理机制。     

HPV疫苗如何走入大众视野？——基于微博相关视频的内容分析

以微博相关视频为研究对象,对选取样本进行内容分析,探究有可能影响公众健康态度和疫苗健康决策的社交媒体内容如何呈现人乳头瘤病毒(human papillomavirus, HPV)疫苗相关议题,并利用扩展的平行过程模式(expended parallel process model,EPPM)对其内容中的“威胁”和“效能”信息分析得出,兼具大众传播功能和人际传播影响力的微博中,不同来源的HPV疫苗视频对HPV健康风险及疫苗改善措施的信息呈现上存在差异,对于HPV疫苗的接种信息呈现不足,有可能影响用户的健康效能,对公众的健康促进需要更加全面、准确、平衡的HPV疫苗信息呈现。

     

关于实验动物运动模型建立的伦理思考

基于目前广泛应用的动物实验伦理3R和5F原则,通过深入分析已有运动干预文献中的动物运动模型构建方法,分别就运动模型建立前实验动物的选取,运动模式、运动剂量的确定,模型建立过程中不同阶段不同运动形式所涉及的伦理问题,以及实验动物安乐死等各个方面进行伦理分析,探讨伦理关怀在动物运动模型建立中的必要性和重要性。运动模型的构建作为研究运动干预的关键环节是极其重要的,此建立过程中涉及到诸多动物实验伦理问题。
