The implicative dilemma (ID) is gradually receiving attention of clinical psychologists and researchers. Although research on its clinical relevance is promising, there are still some issues regarding its measurement that need further consideration. This article explores the adequacy of the different thresholds used to determine construct association, the efficacy of the different indices commonly used to measure IDs, and a verification of the ID not being a mere subproduct of the self-ideal distance. It also introduces a new index. Finally, guidelines are provided for practitioners on how to interpret the indices' numerical results in relation to major depression.  相似文献

论动态稳定     
目前,人类认识在两方面取得了共识:一方面,认识到了可持续发展的意义.另一方面,认识到了可持续发展与稳定的关系,并提出稳定是压倒一切的主题。现在的问题是,对稳定主要是从平衡方面去理解:经济稳定就是经济平衡,自然稳定就是生态平衡等。实际上这仍然是一种静态的稳定,这种平衡的稳定是没有活力的,因而是同进化和发展的目标正相矛盾的。本文则指出,具有活力的稳定是一种非平衡的稳定,其在本质上是一种动态稳定,其同进化和发展的目标正相一致。  相似文献

如何规范城市居民最低生活保障标准的测算   总被引:14,自引:0,他引:14  
洪大用 《学海》2003,(2):122-127
目前,我国城市居民最低生活保障标准的制定和调整比较随意,整体水平偏低,难以有效满足城市贫困人口的基本生活需求,并且没有根据不同家庭的情况执行多元化的弹性标准。为此,需要进一步规范低保标准的测算,其关键是要深入理解《城市居民最低生活保障条例》的有关规定,掌握测算低保标准的科学方法,合理区分不同类型家庭的基本生活需求,坚持共享发展成果,不断调整保障标准的原则,特别是要科学确定低保标准测算的指标体系和测算程序。  相似文献

Standard models of concept learning generally focus on deriving statistical properties of a category based on data (i.e., category members and the features that describe them) but fail to give appropriate weight to the contact between people's intuitive theories and these data. Two experiments explored the role of people's prior knowledge or intuitive theories on category learning by manipulating the labels associated with the category. Learning differed dramatically when categories of children's drawings were meaningfully labeled (e.g., “done by creative children”) compared to when they were labeled in a neutral manner. When categories are meaningfully labeled, people bring intuitive theories to the learning context. Learning then involves a process in which people search for evidence in the data that supports abstract features or hypotheses that have been activated by the intuitive theories. In contrast, when categories are labeled in a neutral manner, people search for simple features that distinguish one category from another. Importantly, the final study suggests that learning involves an interaction of people's intuitive theories with data, in which theories and data mutually influence each other. The results strongly suggest that straight-forward, relatively modular ways of incorporating prior knowledge into models of category learning are inadequate. More telling, the results suggest that standard models may have fundamental limitations. We outline a speculative model of learning in which the interaction of theory and data is tightly coupled. The article concludes by comparing the results to recent artificial intelligence systems that use prior knowledge during learning.  相似文献

Deliberate self-harm has recently begun to receive more systematic attention from clinical researchers. However, there remains a general lack of consensus as to how to define and measure this important clinical construct. There is still no standardized, empirically validated measure of deliberate self-harm, making it more difficult for research in this area to advance. The present paper provides an integrative, conceptual definition of deliberate self-harm as well as preliminary psychometric data on a newly developed measure of self-harm, the Deliberate Self-Harm Inventory (DSHI). One hundred and fifty participants from undergraduate psychology courses completed research packets consisting of the DSHI and other measures, and 93 of these participants completed the DSHI again after an interval of 2–4 weeks (M = 3.3 weeks). Preliminary findings indicate that the DSHI has high internal consistency; adequate construct, convergent, and discriminant validity; and adequate test-retest reliability.  相似文献

Authors of many statistical texts and review articles have pointed to the possi- ble adverse effects that outliers can have on the calculation of sample statistics and have suggested several methods for detecting and treating outliers. We investigated two different methods-data censoring and transformation-for treating outliers in aptitude test data at the item level and total-score level and their effects on the internal consistency and predictive validity of six computer- ized tests being evaluated by the U.S. Air Force. Results from our sample of more than 2,000 pilot training candidates indicated that neither outlier treat- ment method at either level of analysis had significant effects on the tests' internal consistencies or predictive validities. Possible reasons for these findings include the frequency with which outliers occur and the robustness of linear modeling methods.  相似文献

More than 30 years of research has established psychological hardiness as an important individual resiliency resource. One important question still remaining is whether psychological hardiness can be trained. The present study explored this question longitudinally within the context of a 3-year military academy training program. Cadets from 3 different Norwegian military academies (N = 293) completed hardiness questionnaires during the first week of their training, and then again at the end of each year, resulting in a total of 4 waves of data. Using hierarchical linear modeling, no statistically significant effect of time on hardiness scores was found. The nonsignificant growth parameter was examined further using Bayesian statistics as an indicator of the relative evidence for the null hypothesis of no change over time versus the alternative hypothesis of change. The resulting Bayes factor provided substantial support in our data for the null hypothesis of no hardiness development during the 3-year officer training programs.  相似文献

If measurement invariance does not hold over 2 or more measurement occasions, differences in observed scores are not directly interpretable. Golembiewski, Billingsley, and Yeager (1976) identified 2 types of psychometric differences over time as beta change and gamma change. Gamma change is a fundamental change in thinking about the nature of a construct over time. Beta change can be described as respondents' change in calibration of the response scale over time. Recently, researchers have had considerable success establishing measurement invariance using confirmatory factor analytic (CFA) techniques. However, the use of item response theory (IRT) techniques for assessing item parameter drift can provide additional useful information regarding the psychometric equivalence of a measure over time that is not attainable with traditional CFA techniques. This article marries the terminology commonly used in CFA and IRT techniques and illustrates real advantages for identifying beta change over time with IRT methods rather than typical CFA methods, utilizing a longitudinal assessment of job satisfaction as an example.  相似文献

Single-case designs provide an established technology for evaluating the effects of academic interventions. Researchers interested in studying the long-term effects of reading interventions often use curriculum-based measures of reading (CBM-R) as they possess many of the desirable characteristics for use in a time-series design. The reliability of CBM-R scores is often supported by research from group designs, but making idiographic interpretations regarding the change in a student’s oral reading rate requires attention to the precision of static scores and growth estimates. The purpose of this paper is twofold. First, we discuss how recent empirical work on the technical adequacy of CBM-R scores has revealed multiple threats to the data-evaluation validity when CBM-R passages are used to measure oral reading rate. Second, we identify pertinent considerations for conducting a visual analysis of intervention effects based on CBM-R data. We conclude with a brief discussion of implications for researchers considering the use of CBM-R within multiple-baseline designs.  相似文献

大数据技术的进步,给传统科学哲学带来了诸多挑战。科学哲学家们需要重新思考数据的本质,进而深入思考数据的特性以及与信息的内在关联。对数据本质的理解主要有两种:一是关系论,二是表征论。以大数据技术的发展为依据,可知关系论更加合理,同时可将信息解释为数据加意义。数据和现象的区分,可以进一步为我们提供理解数据之本质的途径。从大数据的发展看数据和现象的区分,可以得知在不同语境中对数据的定义是不同的,因此数据的两种定义其实并没有冲突。通过对香农的信息定义的解读,可知信息和数据之间有着内在的关联,二者是关系实体的不同表述方式。解决问题的关键在于该定义所使用的语境,以及是否赋予意义在此关系之上,因此数据就是信息,万物皆可信息化或数据化。  相似文献
