用信息函数法对标准参照测验作质量分析   总被引:1,自引:0,他引:1  
根据项目反应理论的信息函数法,以自主开发的“现代教育和心理测量通用分析系统”为工具,对两个大规模实施的标准参照测验进行了测验质量分析。结果说明,信息函数分析法比经典真分数理论分析法,可以获得更丰富、深刻、有针对性的资料,能对项目筛选修订、测验编制开发给出有力的指导,值得大力引进、推广。  相似文献

公正:城市反贫困的伦理标准   总被引:1,自引:0,他引:1  
公正是人类社会追求的永恒价值理想 ,也是社会发展过程中需要妥善处理的一个难点问题。随着中国社会转型进程的日益加快 ,社会各阶层贫富差距的不断拉大 ,公正原则受到社会现实的极大挑战 ,公正原则的普遍实现与否 ,将决定我国城市反贫困工作的成败。基于上述理由 ,笔者从公正的制度化基础、公正的基本原则和公正原则实现的条件等几方面阐述如何以公正为伦理标准来推进城市反贫困工作。  相似文献

Innovative practice occurs when a clinician provides something new, untested, or nonstandard to a patient in the course of clinical care, rather than as part of a research study. Commentators have noted that patients engaged in innovative practice are at significant risk of suffering harm, exploitation, or autonomy violations. By creating a pathway for harmful or nonbeneficial interventions to spread within medical practice without being subjected to rigorous scientific evaluation, innovative practice poses similar risks to the wider community of patients and society as a whole. Given these concerns, how should we control and oversee innovative practice, and in particular, how should we coordinate innovative practice and clinical research? In this article, I argue that an ethical approach overseeing innovative practice must encourage the early transition to rigorous clinical research without delaying or deferring the development of beneficial innovations or violating the autonomy rights of clinicians and their patients.  相似文献

追踪研究是一种通过引入时滞, 以探索变量动态变化趋势和变量之间相互关系的调查研究方法。近年来, 在组织行为学中, 追踪研究越来越受到学者们的关注, 追踪研究成果也在逐渐增加, 但是大多数研究者尤其是国内研究者, 对追踪研究尚缺乏全面正确的认识。追踪研究设计可以依照重复测量之间的时间间隔长短进行分类, 不同的类型对应不同的样本量、调查方式和统计分析方法, 未来可以拓展追踪研究在团队和领导力、组织文化和变革以及员工激励等方面的应用, 或开展跨文化的追踪研究。  相似文献

Background/ObjectiveThe Short Health Anxiety Inventory (SHAI) is a widely used self-report instrument to evaluate health anxiety. To assess the SHAI's factor structure, psychometric properties, and accuracy in differentiating Spanish non-clinical individuals from patients with severe health anxiety or hypochondriasis.MethodA total of 342 community participants (61.6% women; Mage = 34.60, SD = 14.91) and 31 hypochondriacal patients (51.6% women; Mage = 32.74, SD = 9.69) completed the SHAI and other self-reports assessing symptoms of hypochondriasis, depression, anxiety sensitivity, worry, and obsessive-compulsive.ResultsThe original two-factor structure was selected as the best structure, based on its parsimony and empirical support (Factor 1: Illness likelihood; Factor 2: Negative consequences of illness). Moreover, the Spanish version of the SHAI demonstrated good construct and concurrent and discriminant validity, and internal consistency. A cutoff of 40.5 (total score) accurately distinguished non-clinical individuals from patients with severe health anxiety or hypochondriasis.ConclusionsThe SHAI is an adequate screening instrument to measure health anxiety in Spanish-speaking community adults.  相似文献

科学的划界与医学:—一论在医学中坚持科学精神   总被引:2,自引:1,他引:1  
这里所论的科学划界标准是就自然科学而言的,区分科学与非科学最重要的标准是它的可检验性和可重复性。科学的这个划界标准今天并未过时,医学和一般自然科学相比有其特点,但其为实验科学的医学也应坚持这个标准。  相似文献

Aggressiveness has been one of the behavioral traits most examined with various standard testing methods. We used two distinct methods (the mirror and the real opponent tests) to evaluate individual aggression and relate it to the activity and individual stress of chub (Squalius cephalus L.). Three hypotheses were formulated and tested: (a) there is a significant positive relationship between the aggressiveness of individuals measured with the mirror and the real opponent tests, indicating their convergent validity; (b) the irregularities in response to the aggressiveness and activity tests lead to the context-specific expression of the behavioral syndromes; and (c) there is a significant positive relationship between the stress induced in individuals by both tests of aggressiveness, demonstrating individually consistent stress-coping strategies. The first and the second hypothesis were confirmed, while the third hypothesis was rejected. Our results suggest that particular tests of aggressiveness could act as a situation with high strength, leaving little variation between individual responses. Thus, we propose that for the proper interpretation of various studies using different tests to study identical behavioral traits, it is important to consider the convergent validity of not only the tested behavioral traits but also the individual stress responses. The chub also showed stress relieve through aggressiveness, suggesting the species as a prospective animal model to the study interaction between the stress and the aggressiveness. A detailed aggression ethogram of chub was provided to facilitate the use of this specie in future studies.  相似文献

Abstract

In two experiments, we examined younger and older participants’ appraisals of memory failures in fictitious characters portrayed as younger (in their 20’s to 30’s) or older (in their 60’s to 70’s) adults. Participants read vignettes where forgetful behavior had minor or more severe consequences for the target character (Experiment 1) or for the character and others in the social environment (Experiment 2). Participants rated potential causes of the forgetfulness and opinions concerning the target character’s cognitive health. In Experiment 1, an age-based double standard was observed, where both age groups rated ability as a cause of forgetting more often for older than younger characters. Ratings of forgetfulness as a sign of mental difficulty, need for memory training, and professional evaluation were also higher for older compared to younger characters. In Experiment 2, the Attribution Type by Target Age interaction effect was replicated. Ability and effort contributed to the significance of the interaction, confirming the reliability and generalizability of the age-based double standard. Forgetfulness was rated as a sign of mental difficulty more often for the older than younger characters, replicating Experiment 1. In both experiments, the consequences of the forgetting had a large impact on the attribution and opinion ratings for younger and older forgetful characters. These data suggest that people of all ages evaluate forgetful characters in light of situational outcomes as well as ageist presumptions of cognitive frailty in later life.  相似文献
