Interjurisdictional Certification and Choice of Law
There is a story, probably apocryphal, that, at a 1970s conference discussing the great potential and even greater problems of some economically developing countries, a rather cynical American economist is supposed to have remarked that Brazil is the country of the future-and always will be. Some commentators believe that much the same could be said about the certification process, but with greater accuracy. Certification has beguiled and to some extent disappointed two generations of legal scholars.\u27 Intended to resolve problems that arise when a court of one jurisdiction must apply the law of another jurisdiction, certification is the process by which the first court may inquire of a court in the jurisdiction whose law is at issue for help in determining what the law is. The certification process is inherently attractive be-cause it eliminates the need for a court either to guess at another jurisdiction\u27s uncertain law or to refrain altogether from trying to apply that law.
The difficulty that certification can ease typically arises in one of two situations. The first situation occurs when a federal court, for whatever reason, must identify and apply the substantive law of a state.Federal courts hearing diversity cases are the most likely to inquire into state law, but the problem can also arise when a federal court\u27s subject-matter jurisdiction is based on the presence of a federal question. The second situation occurs when a state court\u27s own conflict-of-laws rules direct it to apply the law of another state
Shigella sonnei oligosaccharide-protein conjugates
AbstractSynthetic oligosaccharides composed of several repeats of Shigella dysenteriae type 1 O-specific polysaccharide (O-SP), bound by their reducing ends to a carrier protein (“sun” type configuration), induced in mice significantly higher antibody levels than conjugates of the native O-SP (“lattice” type configuration). Here we present isolation and characterization of low molecular mass oligosaccharides of Shigella sonnei lipopolysaccharides and their conjugation to several carrier proteins. Conjugates were formed by oxime linkages between the terminal Kdo residues of the reducing ends of the saccharides and aminooxy linkers bound to the protein. IgG antibody levels induced in young outbread mice by these conjugates were significantly higher than those prepared with the full length native O-SP. We propose clinical evaluation of the new S. sonnei conjugates
Acceleration and Substructure Constraints in a Quasar Outflow
We present observations of probable line-of-sight acceleration of a broad
absorption trough of C IV in the quasar SDSS J024221.87+004912.6. We also
discuss how the velocity overlap of two other outflowing systems in the same
object constrains the properties of the outflows. The Si IV doublet in each
system has one unblended transition and one transition which overlaps with
absorption from the other system. The residual flux in the overlapping trough
is well fit by the product of the residual fluxes in the unblended troughs. For
these optically thick systems to yield such a result, at least one of them must
consist of individual subunits rather than being a single structure with
velocity-dependent coverage of the source. If these subunits are identical,
opaque, spherical clouds, we estimate the cloud radius to be r = 3.9 10^15 cm.
If they are identical, opaque, linear filaments, we estimate their width to be
w = 6.5 10^14 cm. These subunits are observed to cover the Mg II broad emission
line region of the quasar, at which distance from the black hole the above
filament width is equal to the predicted scale height of the outer atmosphere
of a thin accretion disk. Insofar as that scale height is a natural size scale
for structures originating in an accretion disk, these observations are
evidence that the accretion disk can be a source of quasar absorption systems.

AVIAN SPECIATION IN THE PANTEPUI: THE CASE OF THE RORAIMAN ANTBIRD (PERCNOSTOLA [SCHISTOCICHLA] ‘‘LEUCOSTIGMA’’ SATURATA)
This is the published version. Copyright Central Ornithology Publication OfficeWe document the first records for Guyana of Roraiman Antbird (Percnostola [Schistocichla] “leucostigma” saturata), an endemic of the tepui highlands of southeastern Venezuela, northern Brazil and western Guyana. This form is well differentiated from nominate leucostigma (Spot-winged Antbird) of the Guianan lowlands in morphology, vocalizations, and genetics, and replaces it both altitudinally and ecologically. The two taxa are distributed parapatrically on the continuously forested northeastern slopes of the eastern tepuis, and they almost certainly come into contact, yet there is no evidence of intermediacy. We recommend that saturata be treated as a distinct species of Percnostola, and consider its' origin in the light of various models of speciation in the tepuis

Professor Husband\u27s book deals with two problems, the date of the trial and crucifixion of Jesus, and the legal aspects of the proceedings against him. In both divisions of the subject his conclusions are novel and are supported by able argumentation

Greenland Ice Sheet Mass Balance: Distribution of Increased Mass Loss with Climate Warming; 2003-07 Versus 1992-2002
We derive mass changes of the Greenland ice sheet (GIS) for 2003-07 from ICESat laser altimetry and compare them with results for 1992-2002 from ERS radar and airborne laser altimetry. The GIS continued to grow inland and thin at the margins during 2003 07, but surface melting and accelerated flow significantly increased the marginal thinning compared with the 1990s. The net balance changed from a small loss of 7 plus or minus 3 Gt a 1(sup -1) in the 1990s to 171 plus or minus 4 Gt a (sup -1) for 2003-07, contributing 0.5 mm a(sup -1) to recent global sea-level rise. We divide the derived mass changes into two components: (1) from changes in melting and ice dynamics and (2) from changes in precipitation and accumulation rate. We use our firn compaction model to calculate the elevation changes driven by changes in both temperature and accumulation rate and to calculate the appropriate density to convert the accumulation-driven changes to mass changes. Increased losses from melting and ice dynamics (17-206 Gt a(sup-1) are over seven times larger than increased gains from precipitation (10 35 Gt a(sup-1) during a warming period of approximately 2 K (10 a)(sup -1) over the GIS. Above 2000m elevation, the rate of gain decreased from 44 to 28 Gt a(sup-1), while below 2000m the rate of loss increased from 51 to 198 Gt a(sup-1). Enhanced thinning below the equilibrium line on outlet glaciers indicates that increased melting has a significant impact on outlet glaciers, as well as accelerating ice flow. Increased thinning at higher elevations appears to be induced by dynamic coupling to thinning at the margins on decadal timescales
