Commonality in Returns, Order Flows, and Liquidity in the Greek Stock Market

Using a unique high-frequency data-set on a comprehensive sample of Greek blue-chip stocks, spanning from September 2003 through March 2006, this note assesses the extent and role of commonality in returns, order flows (OFs), and liquidity. It also formally models aggregate equity returns in terms of aggregate equity OF, in an effort to clarify OF's importance in explaining returns for the Athens Exchange market. Almost a quarter of the daily returns in the FTSE/ATHEX20 index is explained by aggregate own OF. In a second step, using principal components and canonical correlation analyses, we document substantial common movements in returns, OFs, and liquidity, both on a market-wide basis and on an individual security basis. These results emphasize that asset pricing and liquidity cannot be analyzed in isolation from each other.

To avoid embarrassment, poetry should keep itself to itself”: an autoethnographic exploration of the place of poetry in adult literacy teacher education

This paper explores the reasons for the author’s reluctance to bring examples of her own poetry into her practice as teacher educator on a program for adult literacy tutors. The paper begins with the author’s poem, “The Place of Poetry”, which is used as a tool for reflection on the author’s assumptions about her identities as poet and as educator. The paper ends with poems written by the author’s students, which demonstrate that the use of poetry in education has the potential to facilitate transformative learning.

The Sacred and the Obscure: Greek in the Carolingian Reception of Martianus Capella

Carolingian scholars paid considerable attention to the Greek found in Martianus Capella’s De nuptiis Philologiae et Mercurii, a late antique Latin work full of obscurities in language and imagery. This article, focusing on glosses on De nuptiis from the oldest gloss tradition, demonstrates that a range of material was available to ninth-century scholars to elucidate Martianus’s Greek and that Greek seems, at times, to have served as a means to obscure. I argue that their interest in obscurity reflects a widespread epistemology and strategy of concealment, hence their intellectual investment in Martianus. For ninth-century readers, then, the Greek in the glossed Martianus manuscripts, however decorative it may have been, also operated at the core of medieval hermeneutics.
