Racing the Rising Tide: Legal Options for the Marshall Islands
This Note first describes the threat posed by accelerated sea-level rise. A review of scientific data shows that global warming causes ocean levels to rise and that RMI may need to be evacuated. The current diplomatic efforts to decrease global warming offer few assurances to RMI. In fact, the countries that have obligated themselves to reduce global warming are actually increasing emissions of gases that cause global warming
Is Newer Better? Penn World Table Revisions and Their Impact on Growth Estimates
This paper sheds light on two problems in the Penn World Table (PWT) GDP estimates. First, we show that these estimates vary substantially across different versions of the PWT despite being derived from very similar underlying data and using almost identical methodologies; that this variability is systematic; and that it is intrinsic to the methodology deployed by the PWT to estimate growth rates. Moreover, this variability matters for the cross-country growth literature. While growth studies that use low-frequency data remain robust to data revisions, studies that use annual data are less robust. Second, the PWT methodology leads to GDP estimates that are not valued at purchasing power parity (PPP) prices. This is surprising because the raison d’être of the PWT is to adjust national estimates of GDP by valuing output at common international (PPP) prices so that the resulting PPP-adjusted estimates of GDP are comparable across countries. We propose an approach to address these two problems of variability and valuation.purchasing power parity; penn world table; methodology; growth; gdp estimates; cross-county data
Building Capacity to Improve Latino Health in Rural North Carolina: A Case Study in Community-University Engagement
In North Carolina, health disparities for the emergent Latino population are well documented. Between 2005 and 2009, a community-university engagement model with Latino leaders and university faculty and students in rural eastern North Carolina worked to address solutions to health disparities among Latinos. Based on principles of community-based participatory research, this model focused on partnership formation and capacity building. Community partners acquired leadership and research skills. University partners gained a local understanding of Latino health through collaborative community and systems-level initiatives. Mutual benefits were achieved in partnerships established, resources leveraged, and community members reached. These strategies can be replicated in other communities that have an immigrant Latino population, community-oriented, bilingual health professionals, and a university committed to engagement
Renner-Teller effects in HCO+ dissociative recombination
A theoretical description of the dissociative recombination process for the
HCO+ ion suggests that the nonadiabatic Renner-Teller coupling between
electronic and vibrational degrees of freedom plays an important role. This
finding is consistent with a recent study of this process for another
closed-shell molecule, the H3+ ion, where Jahn-Teller coupling was shown to
generate a relatively high rate. The cross section obtained here for the
dissociative recombination of HCO+exhibits encouraging agreement with a
merged-beam experiment.Comment: 11 page

Extended treatment with MY-NEOVAX, personalized neoantigen-enhanced oncolytic viruses, for two end-stage cancer patients.
Neoantigen vaccines involving multi-peptides and poly-epitope-encoding RNA or DNA have undergone early phase clinical testing with modest reported antitumor effects [ 1]. The less-than-expected activity of these neoantigenic vaccines may correspond with the development of immune escape mechanisms. One permutation on neoantigen vaccines, which may counter or prevent these adaptive immune escape mechanisms, are 'personalized' oncolytic viruses that encode one or more tumor-specific transgenes. Herein, positive therapeutic effects for MY-NEOVAX™, personalized neoantigen-enhanced oncolytic adenoviruses, are described for two heavily pretreated end-stage patients, one with high-grade metastatic neuroendocrine carcinoma of the pancreas and the other with colorectal cancer metastatic to the brain, liver and lungs. To date, treatment benefit has exceeded 12 months without dose-limiting toxicities or related serious adverse events and with documented radiologic stabilization and improved performance status
Relationships between inventory, sales and service in a retail chain store operation
Effective inventory management is critical to retailing success. Surprisingly, there islittle published empirical research examining relationships between retail inventory, sales andcustomer service. Based on a survey of 101 chain store units, this paper develops and tests aseries of hypotheses about retail inventory. Seventy-five percent of the store owners/managersresponded to the mail survey. As expected, significant positive relationships were found betweeninventory, service and sales. Specifically, support was found for the theory that inventory is afunction of the square root of sales. Also, greater product variety leads to higher inventory, andservice level is an exponential function of inventory. Finally, demand uncertainty was found tohave no apparent effect on inventory levels
UV Interstellar Absorption Lines towards the Starburst Dwarf Galaxy NGC 1705
Archival Goddard High Resolution Spectrograph low-resolution spectra of NGC
1705, with wavelength ranges 1170.3 to 1461.7 A and 1453.5 to 1740.1 A and a
velocity resolution of about 100 km\s, have been used to derive the velocity
structure and equivalent widths of the absorption lines of Si II 1190.42,
1260.42, 1304.37 and 1526.71 A, S II 1253 , Al II 1670.79 Aand Fe II 1608.45 A
in this sightline. Three relatively narrow absorption components are seen at
LSR velocities --20 km/s, 260 km/sand 540 km/s. Arguments are presented to show
these absorption features are interstellar rather than stellar in origin based
on a comparison with the C III 1175.7 A absorption feature. We identify the
--20 km/s component with Milky Way disk/halo gas and the 260 km/s component
with an isolated high-velocity cloud HVC 487. This small HVC is located about
10 degrees from the H I gas which envelops the Magellanic Clouds and the
Magellanic Stream (MS). The (Si/H) ratio for this HVC is > 0.6 (Si/H)solar
which together with velocity agreement, suggests association with the
Magellanic Cloud and MS gas. H-alpha emission line kinematics of NGC 1705 show
the presence of a kpc-scale expanding supershell of ionized gas centered on the
central nucleus with a blue-shifted emission component at 540 km/s (Meurer et
al. 1992). We identify the 540 km/s absorption component seen in the GHRS
spectra with the front side of this expanding, ionized supershell. The most
striking feature of this component is strong Si II and Al II absorption but
weak Fe II 1608 A absorption. The low Fe II column density derived is most
likely intrinsic since it cannot be accounted for by ionization corrections or
dust depletion. Due to their shallow gravitational potential wells, dwarf
galaxies have small gravitational binding energies and are vulnerable to largeComment: 15 pages, LaTEX, 1 figure. Accepted for publication in Astrophysical
