通过应用中国城市家庭消费金融调研数据,本文系统的实证检验了改进后的金融知识指标、经济学专业、金融学专业以及家庭理财规划等因素对家庭各项财富积累的影响,并通过使用合适的工具变量进行两阶段估计,验证了这种正向影响的稳健性。此外,实证结果中家庭理财规划以及理财规划时间跨度的正向边际效应表明,理财规划可能是金融知识差异影响家庭财富积累的重要机制。研究结论有利于更准确地理解居民金融知识差异对于家庭福利,特别是退休福利的影响。 相似文献

As Latinx teachers are recruited to work in U.S. schools, a continued agenda to understand their experiences is warranted. This multiple case study considers the storytelling of six Latinx teachers in a new Latinx diaspora community. It documents both their racial literacy (the ability to resolve racially stressful issues) and their experiences with (un)masking (literal and figurative ways to cover or embrace racial markers). This study reveals the tensions that arise when Latinx teachers attempt to define their identity in social spaces where their languages, bodies, and names, among other markers, are racialized when read by others. Implications for teacher education include a call to include storytelling as a pedagogical tool to develop Latinx teachers’ racial literacy skills. By experiencing storytelling in their own schooling, Latinx teachers are more likely to model such racial literacy skills in their schooling communities; thereby, empowering a generation of students to enact more humanizing behaviors. 相似文献

In quantitative trait linkage studies using experimental crosses, the conventional normal location-shift model or other parameterizations may be unnecessarily restrictive. We generalize the mapping problem to a genuine nonparametric setup and provide a robust estimation procedure for the situation where the underlying phenotype distributions are completely unspecified. Classical Wilcoxon–Mann–Whitney statistics are employed for point and interval estimation of QTL positions and effects. 相似文献

早在社会学诞生之初,其创始人孔德就将社会学确定为一门关于"社会的科学",称社会学为"实证的哲学".由于科学自身以及科学研究方法存在的局限性,这也意味着作为科学的社会学一系列问题的开始.正因如此,对于社会学的科学性含义,社会学实证方法的重要性,定量研究对于社会学理论发展的基础性意义等,有必要作进一步探讨. 相似文献

The authors conducted an online survey of elementary teacher education programs within a large midwestern state to assess preservice teachers’ and teacher educators’ beliefs about and preparedness to teach financial literacy. Very few preservice teachers had meaningful experiences with personal finance in high school, college, or personal decision making. No teacher educators reported ever teaching financial literacy in their higher education roles. Only 13% of teacher educators and 25% of preservice teachers thought that it was very important to teach financial literacy in elementary education. Most teacher education faculty and preservice teachers reported that they were not well qualified to use state economics standards or the JumpStart standards for financial literacy. Preservice teachers were more confident in meeting financial literacy standards than teacher educators. Both preservice teachers and teacher educators expressed openness to collaborating with other faculty members, members of the financial service industry, and parents to teach financial literacy. Follow-up phone interviews affirmed that elementary preservice teachers and teacher educators value social studies education (and financial literacy) less than reading and mathematics education. Qualitative results also suggest that elementary preservice teachers and teacher educators would like more easily accessible resources for teaching financial literacy. 相似文献

In this article, we introduce for the first time, the blank card methods for estimation of finite population mean of a sensitive variable. Two generic randomization devices are suggested, and for each device we identify the choices of special models. We introduce additive, multiplicative, and combination of both additive and multiplicative scrambling models that require use of a non sensitive variable. We derive the basic statistical properties of each model. It is interesting to note that various existing estimators can be viewed as the special cases of those presented here. The statistical efficiency of proposed techniques is compared with Greenberg et al. (1971) and modified Perri (2008) model. The proposed devices can easily be adjusted to achieve the required efficiency level by making suitable choices of different design parameters. 相似文献

提高媒介素养、加强媒介素养教育的呼声随着大众传媒日益深广的影响而显得越来越迫切。调查表明,理工科大学生对媒介资源的运用趋向理性,但对媒介素养的认知和批判能力的欠缺,反映了其媒介素养不够。同时,理工科大学生对媒介素养教育的主动参与性还远远不够。 相似文献

以广西桂林高校理工科大学生为样本,对英美文学对学生创新思维培养的实证分析表明:理工科大学生英美文学水平总体不高,创新思维能力呈中等水平;选(必)修英美文学课程不仅能提高学生英美文学素养,也促进了学生创新思维能力的发展;学生英美文学水平与创新思维能力呈中度正相关。因此,理工科院校应倡导学生重视自身英美文学素养的提高,并积极开设英美文学选(必)修课程,努力推进专业学科与人文学科的有机结合,以培养具有全面素质的优秀人才。 相似文献
