Effect of Lockup Agreements on Buyout Backed Initial Public Offerings

Using a sample of 279 buyout backed firms, I examined the effect of lockup agreements on the firm’s stock returns. I found there to be a negative .8 percent cumulative abnormal return for the three-day period surrounding lockup expiration. Consistent with my hypothesis the CAR for the three-day period surrounding lockup expiration was less negative for buyout backed IPOs compared to venture capital backed IPOs. In addition, I found there to be an abnormal 24.24 percent increase in trading volume for the three days surrounding lockup expiration

Preliminary Observations on Oyster Pearl Net Cultivation in Coastal Georgia

This work reports on survivorship and growth rates attained by a transplanted northern stock of Crassostrea virginica (x̄ = 15 mm) tested at various densities in pearl nets in sheltered and exposed sites in coastal Georgia (October 1985 - August 1986). Monthly growth increments ranged from 4.5 to 5.1 mm (shell height). One hundred oysters per net was the optimum stocking density. One hundred percent mortality was suffered at both sites during June - August (probably due to Perkinsus marinus). Current growth rates indicate a growth to market size time of 18 months or less for 15 mm seed grown in pearl nets. However, pearl net cultivation is shown to have serious drawbacks as an oyster grow-out system for coastal Georgia and alternative systems are discussed

The Effects of Cage Mesh Size and Tidal Level Placement on the Growth and Survival of Clams, Mercenaria mercenaria (L.) and Spisula solidissima (Dillwyn), in the Coastal Waters of Georgia

This work reports on the effects of cage mesh size and tidal level placement upon the growth and survival of the hard clam, Mercenarla mercenaria (L.), and the surf clam, Spisula solidissima (Dillwyn), In the coastal waters of Georgia. Surf clams (N = 50 per cage) and hard clams (N = 100 per cage) were each planted in replicated (N = 2) cages constructed of 3 mm, 6 mm, 13 mm and 19 mm mesh vexar plastic at various tidal levels. Cages were deployed by partial burial at the mean and the spring low water marks. At termination of the surf clam trial (6 months), there were no significant differences in survival determined for clams planted in different mesh cages at either tidal level or for clams grown in equivalent mesh size cages between tidal levels. There were significant differences In clam size with surf clams at the spring low water growing significantly larger than those at the mean low water mark. There were also significant differences In surf clam growth between different mesh size cages. Surf clams from 6 mm cages were smaller than those from other cages, while the largest clams reared were in the 13 mm and 19 mm mesh cages. Hard clam trials (15 month duration) illustrated that cage mesh size induced significant differences in survlval of hard clams. Significantly fewer clams survived In 19 mm mesh cages than in cages of smaller mesh at both tidal levels. No significant differences in hard clam survival were detected among other mesh sizes nor between tidal levels; neither were significant differences between tidal levels determined for equivalent mesh sizes. Significant differences in hard clam growth were determined for clams grown in different mesh size cages and between tidal levels. Clam growth was greater at the spring low water mark. Clams grew larger in 3 mm mesh cages, least In 13 mm mesh cages with no significant differences In growth in the 6 and 19 mm mesh cages. Statistical analyses (t-tests) Illustrated differences in clam growth among replicates at the spring low water mark. Growth may have been reduced in one set of cages as a result of cage excavation by currents. In Georgia, hard and surf clam growth was found to be dependent upon cage mesh size. Clam survival was Independent of cage mesh size as long as the initial size of the seed animals was greater than the mesh size of the cage

Lethal Parasites in Oysters from Coastal Georgia with Discussion of Disease and Management Implications

Extensive mortalities of oysters, Crassostrea virginica, occurred from 1985 through 1987 in coastal waters of Georgia. Fluid thioglycolate cultures of oysters collected from 16 of 17 locations revealed infections by the apicomplexan parasite Perkinsus marinus. An ascetosporan parasite, Haplosporidium nelsoni, was also observed in histopathological examination of oysters from 4 of the locations. While the range of H. nelsoni currently is recognized as the east coast of the United States from Maine to Florida, this is the first report of the parasite in Georgia waters. This paper documents the occurrence of these two lethal parasites in oysters from coastal waters of Georgia, along with potential disease and management implications. Results of an earlier independent and previously unpublished survey are also discussed which document the presence of P. marinus in Georgia as early as 1966

Fluoroscopic imaging overestimates the screw tip to subchondral bone distance in a cadaveric model of slipped capital femoral epiphysis

PURPOSE: Intra-operative imaging plays a key role in screw placement for slipped capital femoral epiphysis (SCFE). Complications have been associated with inadequate screw position. The purpose of this study was to evaluate computed tomography (CT) (3D fluoroscopy) and standard fluoroscopy (C-arm) images as compared with direct anatomic measurement to determine final screw position in a cadaveric SCFE model. METHODS: Osteotomy with pinning was performed at the physeal scar in ten cadaveric hips. A standardised approach-withdrawal technique was performed with C-arm images taken at 15 degrees increments. We also obtained a CT (3D fluoroscopy) scan of each hip. The screw tip-subchondral bone (STSB) distance was measured on digital imaging software and also with a digital calliper directly when the femoral head was cut in plane to expose the STSB distance anatomically. Statistical analysis included t-tests and Fisher\u27s exact test. RESULTS: Moderate SCFE osteotomies were achieved with a mean Southwick angle (39.5 degrees +/- 7 degrees ). The 60 degrees fluoroscopic image was found to be the most representative image (41% of the time) compared with both anteroposterior (AP) and lateral images (8% and 21%). Both fluoroscopy (2.7 +/- 0.8 mm, p \u3c 0.001) and CT (1.6 +/- 0.7 mm, p = 0.03) overestimated the STSB distance compared with direct measurement (0.94 +/- 0.51 mm). Two-thirds (67%) of CT measurements were within 1 mm of the cadaveric measurement, while only 20% of C-arm measurements fulfilled this criterion (p = 0.04). CONCLUSIONS: Both standard fluoroscopy and CT overestimated the STSB distance when compared with direct measurement in a cadaveric model of SCFE. Surgeons should be aware of the limitations of intra-operative imaging to determine the STSB distance. We suggest that using the known pitch of a screw (2.9 mm in a 7.3-mm cannulated screw) as an intra-operative tool to help guide screw placement
