Directly Indecomposables in Semidegenerate Varieties of Connected po-Groupoids
We study varieties with a term-definable poset structure, "po-groupoids". It
is known that connected posets have the "strict refinement property" (SRP). In
[arXiv:0808.1860v1 [math.LO]] it is proved that semidegenerate varieties with
the SRP have definable factor congruences and if the similarity type is finite,
directly indecomposables are axiomatizable by a set of first-order sentences.
We obtain such a set for semidegenerate varieties of connected po-groupoids and
show its quantifier complexity is bounded in general
Intertemporal Changes in the Riskiness of REITs
This study investigates the variability in the risk components of REITs over the 1973-1989 period using the cusum test, the cusum of squares test, and the Quandt's log-likelihood ratio method. Four REIT portfolios were formed: an all-REIT portfolio, an equity REIT portfolio, a hybrid REIT portfolio, and a mortgage REIT portfolio. The two-index model was employed and the results indicated that both the market beta and the interest-rate beta of the portfolios were time-varying. In addition, significant shifts in return-generating regimes over time were detected for all four portfolios.
The Venereal Game
The adjective venereal is defined in dictionaries as pertaining to sexual intercourse, but the associated noun, venery, relates either to coital activity or to the hunting of game. Although Venus pursued her prey indiscriminately in bower or bosky dell, in the venereal game only the bosky dell is involved. James Lipton\u27s An Exaltation of Larks lists scores of venereal terms, relics of mediaeval times. Some -- a school of fish, a pride of lions -- are still in general use; others -- a skulk of foxes, a barren of mules -- are still used by specialists; still others have vanished from the general ken. Mr. Lipton goes on to conjure up his own collectives, such as an unction of undertakers, a float of dancers, a dilation of pupils, and a wince of dentists. This is a game open to all. It is played with gusto on Mary Ann Madden\u27s competition page in New York Magazine
