哈贝马斯"交往行动"概念内在要素表明,其交往行动理论是一种社会发展动力的"哲学假说",它只不过是以理论幻想的方式给资本主义社会提供诊断和治疗其弊端的温和谏言。尽管如此,交往行动理论也不乏给人有益的启示。  相似文献   

基于因子分析法的中国电子商务发展水平实证分析     

《信阳师范学院学报(哲学社会科学版)》2019,(3):34-38

电子商务快速发展,对于推动实体经济发展、加快转变产业发展方式、提升区域经济实力具有重大意义。文章借鉴电子商务发展水平评价指标的研究成果,尝试构建电子商务发展水平评价模型,模型包含4个一级指标:地区经济发展水平、区域信息化水平、电子商务发展潜力、商贸物流发展水平,综合运用SPSS统计分析方法深入分析我国各地区电子商务发展水平。结果显示:广东省电子商务发展水平最高,浙江、江苏、北京、上海次之,而甘肃、青海、西藏、宁夏电子商务发展水平最弱,其他省、市、自治区居中。根据分析结果,各地区应该结合自身情况,有针对性地发展电子商务,并且要重视物流基础设施建设,创新电子商务发展模式,以促进我国电子商务产业健康快速发展。  相似文献

Testing Measurement Invariance Across Unobserved Groups: The Role of Covariates in Factor Mixture Modeling     

Yan Wang  Eunsook Kim  John M. Ferron  Robert F. Dedrick  Tony X. Tan  Stephen Stark 《Educational and psychological measurement》2021,81(1):61

Factor mixture modeling (FMM) has been increasingly used to investigate unobserved population heterogeneity. This study examined the issue of covariate effects with FMM in the context of measurement invariance testing. Specifically, the impact of excluding and misspecifying covariate effects on measurement invariance testing and class enumeration was investigated via Monte Carlo simulations. Data were generated based on FMM models with (1) a zero covariate effect, (2) a covariate effect on the latent class variable, and (3) covariate effects on both the latent class variable and the factor. For each population model, different analysis models that excluded or misspecified covariate effects were fitted. Results highlighted the importance of including proper covariates in measurement invariance testing and evidenced the utility of a model comparison approach in searching for the correct specification of covariate effects and the level of measurement invariance. This approach was demonstrated using an empirical data set. Implications for methodological and applied research are discussed.  相似文献   

Incorporating Uncertainty Into Parallel Analysis for Choosing the Number of Factors via Bayesian Methods     

Roy Levy  Yan Xia  Samuel B. Green 《Educational and psychological measurement》2021,81(3):466

A number of psychometricians have suggested that parallel analysis (PA) tends to yield more accurate results in determining the number of factors in comparison with other statistical methods. Nevertheless, all too often PA can suggest an incorrect number of factors, particularly in statistically unfavorable conditions (e.g., small sample sizes and low factor loadings). Because of this, researchers have recommended using multiple methods to make judgments about the number of factors to extract. Implicit in this recommendation is that, when the number of factors is chosen based on PA, uncertainty nevertheless exists. We propose a Bayesian parallel analysis (B-PA) method to incorporate the uncertainty with decisions about the number of factors. B-PA yields a probability distribution for the various possible numbers of factors. We implement and compare B-PA with a frequentist approach, revised parallel analysis (R-PA), in the contexts of real and simulated data. Results show that B-PA provides relevant information regarding the uncertainty in determining the number of factors, particularly under conditions with small sample sizes, low factor loadings, and less distinguishable factors. Even if the indicated number of factors with the highest probability is incorrect, B-PA can show a sizable probability of retaining the correct number of factors. Interestingly, when the mode of the distribution of the probabilities associated with different numbers of factors was treated as the number of factors to retain, B-PA was somewhat more accurate than R-PA in a majority of the conditions.  相似文献   

Measuring children’s perceived cost of school science: Instrument development and psychometric evaluation     

《Studies in Educational Evaluation》2021

This investigation addresses the need for valid and reliable instruments that contribute to understanding the factors that lead to the rejection of science-related studies. We discuss the theoretical and methodological limitations of published attitudes toward science questionnaires and describe the development and validation of a short instrument rooted in the cost construct of the expectancy-value model of achievement motivation. We collected data from a sample of six hundred thirty-two 5^th and 6^th (M_age = 10.87; SD = .76) elementary students in Spain. Exploratory and confirmatory factor analysis revealed a parsimonious structure measuring loss of valued alternatives and task effort ​cost. Further psychometric evaluation displayed evidence for convergent, discriminant, and concurrent validity. Likewise, the reliability was acceptable for both three-item scales. These findings support the proposed instrument to measure barriers experienced by Spanish children when studying school science.  相似文献   

模拟情形下中国能源消费和碳排放的预测分析   总被引：1，自引：0，他引：1  

金婷婷  童霞  刘静娴 《南通职业大学学报》2021,(1):58-62

基于中国能源消费"煤多、油贫、气少"和碳排放逐年递增的现状,选取人口规模、经济发展水平、能源消费强度三个影响因子,构建STIRPAT模型,对碳排放量的影响因素进行了实证分析,并预测分析了在基准、低碳和协同低碳三种情形下中国2025—2050年的能源消费量和碳排放量。研究结果表明:在低碳情形和协同低碳情形下,中国的能源需求将分别在2045年和2035年出现拐点;协同低碳情形是实现碳排放峰值的最佳方式;在不同情形下碳排放强度虽有较大差异,但都呈现明显的上升趋势。据此提出了完善低碳经济立法、加快可再生能源发展、鼓励低碳工业化生产、加大科技创新等政策建议。  相似文献
