公共信息与IPO询价制效率的关系研究

基于公共信息来评价IPO询价制效率是IPO领域的理论研究前沿.把IPO询价过程分为初步询价阶段和累计投标询价阶段,以2005年1月1日至2008年12月31日在沪深A股市场依据累计投标结果确定发行价的80只IPO为样本,通过考察询价前、询价期间和询价后的公共信息对询价各阶段生成的价格指标的影响,实证分析公共信息与IPO询价制效率的关系.研究结果表明,中国询价制具有较强的信息揭示能力,价格区间和价格调整反映公共信息的能力强,IPO询价制具有一定的效率;中国初步询价阶段的信息揭示能力强,而累计投标询价阶段信息揭示能力弱;中国IPP询价制效率并不完全有效,价格区间确定时已知的公共信息时价格调整产生显著影响,发行价确定时已知的公共信息对初始收益产生显著影响.

IPO询价机制研究

根据询价中的价格机制、发行人的目标函数、机构投资者的目标函数显示，IPO公司为达到发行收益最大化的目标。应联合保荐机构在询价过程中采取数量歧视，有效地在机构投资者与二级市场投资者之间分配股票数量。越多的二级市场投资者参与如PO认购，发行人可以通过降低机构投资者的外部选择价值来获取更高收益。

A narrative inquiry into familial and school curriculum making: attending to multiple worlds of Aboriginal youth and families

In this paper we draw upon a narrative inquiry alongside urban Aboriginal youth and their families in western Canada; the overall goal of our inquiry was to understand their educational and schooling experiences. Shifting our focus from schools as the only place where curriculum is made, we draw on the conceptualization of children, youth, and families as also engaged as curriculum makers in homes and in communities and in the in-between places of homes and schools. In this paper we explore the multiple curriculum-making worlds of Lane and Donovan, two Aboriginal youth. As part of understanding the multiple worlds and relationships between, and intersections of, multiple worlds, we draw on Lugones' concept of world traveling. We contemplate the importance of understanding lives over time, in geographic places, and social contexts. We wonder how the worlds youth inhabit are shaped by institutional, social, political, and institutional stories, and how these larger narratives shape the ways in which we attend to the lives of youth.     

Exploring How an Elementary Teacher Plans and Implements Social Studies Inquiry

Social studies continues to be marginalized in elementary grades, yet the C3 Framework and its Inquiry Arc offer possibilities for high-quality elementary social studies instruction. However, the C3 Framework requires that teachers possess an adequate understanding of how to implement inquiry within the various social studies disciplines, which we argue is an aspect of the pedagogical content knowledge necessary for effective elementary social studies instruction. This single-case study follows an elementary teacher through her use of the C3 Framework, Inquiry Arc, and a related curriculum approach called the Inquiry Design Model as she conceptualized, planned, and implemented inquiries in her fifth-grade classroom. By incorporating this new knowledge into her existing understanding of social studies pedagogy, as well as her knowledge of her students and specific educational context, the teacher was able to successfully navigate some of the challenges associated with implementing social studies inquiry in elementary classrooms.
