Seasonal Occurrence of the White Shark, Carcharodon carcharias, in Waters off the Florida West Coast, with Notes on its Life History

The white shark, Carcharodon carcharias, is considered rare in the Gulf of Mexico; however, recent longline captures coupled with historical landings information suggest that the species occurs seasonally (winter-spring) within this region. We examined a total of seven adult and juvenile white sharks (185-472 em total length) captured in waters off the west coast of Florida. Commercial longline fisheries were monitored for white sharks during all months (1981-94), but this species was captured only from January to April. All white sharks were captured in continental shelf waters from 37 to 222 km off the west coast of Florida when sea surface temperatures ranged from 18.7° to 21.6°C. Depths at capture locations ranged from 20 to 164 m. Fishing gear typically used in Gulf of Mexico offshore fisheries may not be effective at capturing this species, and the apparent rarity of white sharks in this area may be, in part, a function of gear bias

D-branes and Discrete Torsion II

We derive D-brane gauge theories for C^3/Z_n x Z_n orbifolds with discrete torsion and study the moduli space of a D-brane at a point. We show that, as suggested in previous work, closed string moduli do not fully resolve the singularity, but the resulting space -- containing n-1 conifold singularities -- is somewhat surprising. Fractional branes also have unusual properties. We also define an index which is the CFT analog of the intersection form in geometric compactification, and use this to show that the elementary D6-brane wrapped about T^6/Z_n x Z_n must have U(n) world-volume gauge symmetry.Comment: harvmac, 25 p

Unilateral vs. Bilateral Incentives: Evidence from the U.S. Pork Industry

The idea that individuals adapt their behaviors in response to changes in incentive systems is fundamental to most economic analysis. This paper incorporates the concept of price discovery costs into the incentive theory to offer a theoretical model and empirical evidence on the differential incentive effects of long-term contracts and spot markets. Using the US pork industry case where procuring intertemporally consistent weights of hogs have been critical to pork processors, we show why the effectiveness of unilaterally determined and posted incentive price for the hog quality by the pork packers on the intertemporal consistency erodes and why a bilateral incentive structure built through long-term hog procurement contracts is demanded, in the presence of volatile hog price and feed price movements. The MGARCH model analysis of USDA AMS data supported our hypotheses that long-term hog procurement contracts would help moderate the erosion relative to the spot markets, resulting greater intertemporal consistency of hog weights.long-term contracts, incentive effects, price discovery costs, MGARCH model, Livestock Production/Industries,

NYU and JetBlue: Partnerships that Work

In a knowledge economy, every organization must place a priority on developing talent: finding and keeping the right employees and helping them succeed in life and work is the fulcrum strategy for productivity at all levels. Implementing that strategy is an almost overwhelming proposition that requires enormous resources, particularly in a highly competitive environment. Higher education and employers can benefit from working with each other to maximize human capital, but it is a collaboration that requires flexibility and goodwill on everyone’s part. This article, while introducing some of the literature on partnerships between higher education and corporations, also provides some anecdotal tips on how to proceed; more than anything else, it is a testimonial based on the partnership between New York University (NYU) and JetBlue as to what can be, as opposed to what is

Brief of \u3cem\u3eAmici Curiae\u3c/em\u3e Professors Joshua A. Douglas and Michael E. Solimine, Election Law Scholars, in Support of Petitioners

Professor Joshua A. Douglas and Professor Michael E. Solimine are election law experts who have a particular interest in the procedural aspects of election litigation. Professors Douglas and Solimine are filing this brief because they have a keen interest in ensuring that the federal courts employ the proper procedure in election law cases, as doing so helps to resolve these disputes in a manner that best comports with the unique aspects of the electoral system. This brief explains why district courts should not use the pleading standard from Bell Atlantic Corp. v. Twombly, 550 U.S. 544 (2007) and Ashcroft v. Iqbal, 556 U.S. 662 (2009), in making the threshold determination whether to refer a redistricting case to a three-judge district court. Relying on Professor Douglas’s and Professor Solimine’s experience and expertise in this area, it describes the history of the three-judge district court and explains the strong legal and policy reasons why Congress intended for three-judge district courts to resolve redistricting cases. The single district judge here improperly dismissed this case without referring it to a three-judge district court
