Tearing Down the Wall Between Banking and Commerce: An Evaluation of the Federal Reserve Board\u27s Implementation of the New Standard for Permissible Non-Banking Activities
WORTH A DAM: GLACIER VIEW AND THE PRESERVATION OF WILD AMERICA
Conceived in the mid-1930s and formally proposed in 1943, the Glacier View Dam was an Army Corps of Engineers’ proposal for the North Fork of the Flathead River in northwestern Montana. This 416-foot tall dam would have provided inexpensive hydroelectric power to the region and helped control flooding on the volatile Columbia River watershed. Glacier View would also have flooded 20,000 acres of Glacier National Park, one of the “crown jewels” of the national park system. An ideologically diverse coalition of National Park Service officials, wilderness activists and outdoor recreation enthusiasts organized the defense of Glacier National Park and convinced both the Secretary of the Interior and Secretary of the Army to eliminate the Glacier View Dam from a multi-reservoir plan for the Columbia in 1949.
This dissertation looks at the defeat of the Glacier View Dam from several perspectives and argues that this little-known episode was a seminal moment in the environmental history of the United States. Proponents of the dam believed that Glacier View’s hydroelectric power would create an industrial center in western Montana and help reshape an extractive economy hard hit by the Great Depression, help prevent historic flooding in the region and help win World War Two and the Cold War.
One common alternative to Glacier View was the Paradise Dam on the Clark Fork River, still in the headwaters of the Columbia but outside of national park boundaries. Paradise, however, would have flooded 20,000 acres of the Flathead Indian Reservation, the treaty-guaranteed territory of the Salish, Pend d’Oreille and Kootenai peoples. These confederated Native Americans supported the construction of the Glacier View Dam to preserve their lands and economic base in western Montana.
The defeat of the Glacier View Dam was an important moment in the ascendance of the wilderness movement, one that preceded and inspired the more famous Echo Park Dam controversy in the 1950s. This controversy was an early instance where modern conceptions of wilderness swayed public policy in the United States and helped lead to the passage of the Wilderness Act of 1964 and the Wild and Scenic Rivers Act of 1968
In vitro characteristics and in vivo platelet quality of whole blood treated with riboflavin and UVA/UVB light and stored for 24 hours at room temperature
Background
There is a global increase in whole blood usage and at the same time, emerging pathogens give cause for pathogen reduction technology (PRT). The Mirasol PRT has shown promising results for plasma and platelet concentrate products. Treatment of whole blood with subsequent platelet survival and recovery analysis would be of global value.
Study Design and Methods
A two-arm, open-label laboratory study was performed with 40 whole blood collections in four groups: non-leukoreduced non-PRT-treated, non-leukoreduced PRT-treated, leukoreduced non-PRT-treated, and leukoreduced PRT-treated.
Leukoreduction and/or PRT-treatment was performed on the day of collection, then all WB units were stored at room temperature for 24 h. Sampling was performed after hold-time and after 24-h storage in RT. If PRT-treatment or leukoreduction, samples were also taken subsequently after treatment.
Thirteen healthy volunteer blood donors completed the in vivo study per protocol. All WB units were non-leukoreduced and PRT-treated. Radioactive labeling of platelets from RT-stored, PRT-treated whole blood, sampling of subjects, recovery, and survival calculations were performed according to the Biomedical Excellence for Safer Transfusion Collaborative protocol.
Results
In vitro characteristics show that PRT-treatment leads to increased levels of hemolysis, potassium, and lactate, while there are decreased levels of glucose, FVIII, and fibrinogen after 24 h of storage. All values are within requirements for WB.
In vivo recovery and survival of platelets were 85.4% and 81.3% of untreated fresh control, respectively.
Conclusions
PRT-treatment moderately reduces whole blood quality but is well within the limits of international guidelines. Recovery and survival of platelets are satisfactory after Mirasol treatment.publishedVersio

Imaging Cool Giant Planets in Reflected Light: Science Investigations and Synergy with Habitable Planets
Planned astronomical observatories of the 2020s will be capable of obtaining
reflected light photometry and spectroscopy of cool extrasolar giant planets.
Here we explain that such data are valuable both for understanding the origin
and evolution of giant planets as a whole and for preparing for the
interpretation of similar datasets from potentially habitable extrasolar
terrestrial planets in the decades to follow.Comment: Science white paper submitted to the Astro 2020 Decadal Survey on

Impact of changing the measles vaccine vial size on Niger's vaccine supply chain: a computational model
<p>Abstract</p> <p>Background</p> <p>Many countries, such as Niger, are considering changing their vaccine vial size presentation and may want to evaluate the subsequent impact on their supply chains, the series of steps required to get vaccines from their manufacturers to patients. The measles vaccine is particularly important in Niger, a country prone to measles outbreaks.</p> <p>Methods</p> <p>We developed a detailed discrete event simulation model of the vaccine supply chain representing every vaccine, storage location, refrigerator, freezer, and transport device (e.g., cold trucks, 4 Ă— 4 trucks, and vaccine carriers) in the Niger Expanded Programme on Immunization (EPI). Experiments simulated the impact of replacing the 10-dose measles vial size with 5-dose, 2-dose and 1-dose vial sizes.</p> <p>Results</p> <p>Switching from the 10-dose to the 5-dose, 2-dose and 1-dose vial sizes decreased the average availability of EPI vaccines for arriving patients from 83% to 82%, 81% and 78%, respectively for a 100% target population size. The switches also changed transport vehicle's utilization from a mean of 58% (range: 4-164%) to means of 59% (range: 4-164%), 62% (range: 4-175%), and 67% (range: 5-192%), respectively, between the regional and district stores, and from a mean of 160% (range: 83-300%) to means of 161% (range: 82-322%), 175% (range: 78-344%), and 198% (range: 88-402%), respectively, between the district to integrated health centres (IHC). The switch also changed district level storage utilization from a mean of 65% to means of 64%, 66% and 68% (range for all scenarios: 3-100%). Finally, accounting for vaccine administration, wastage, and disposal, replacing the 10-dose vial with the 5 or 1-dose vials would increase the cost per immunized patient from 0.71US and $1.26US, respectively.</p> <p>Conclusions</p> <p>The switch from the 10-dose measles vaccines to smaller vial sizes could overwhelm the capacities of many storage facilities and transport vehicles as well as increase the cost per vaccinated child.</p
Formal Comparisons of Legislative Institutions: Ideal Points from Brazilian Legislatures
Economic Value of Dengue Vaccine in Thailand
With several candidate dengue vaccines under development, this is an important time to help stakeholders (e.g., policy makers, scientists, clinicians, and manufacturers) better understand the potential economic value (cost-effectiveness) of a dengue vaccine, especially while vaccine characteristics and strategies might be readily altered. We developed a decision analytic Markov simulation model to evaluate the potential health and economic value of administering a dengue vaccine to an individual (≤ 1 year of age) in Thailand from the societal perspective. Sensitivity analyses evaluated the effects of ranging various vaccine (e.g., cost, efficacy, side effect), epidemiological (dengue risk), and disease (treatment-seeking behavior) characteristics. A ≥ 50% efficacious vaccine was highly cost-effective [< 1× per capita gross domestic product (GDP) (60 and cost-effective [< 3× per capita GDP (200. When the total vaccine series was $1.50, many scenarios were cost saving

Individual common variants exert weak effects on the risk for autism spectrum disorders.
While it is apparent that rare variation can play an important role in the genetic architecture of autism spectrum disorders (ASDs), the contribution of common variation to the risk of developing ASD is less clear. To produce a more comprehensive picture, we report Stage 2 of the Autism Genome Project genome-wide association study, adding 1301 ASD families and bringing the total to 2705 families analysed (Stages 1 and 2). In addition to evaluating the association of individual single nucleotide polymorphisms (SNPs), we also sought evidence that common variants, en masse, might affect the risk. Despite genotyping over a million SNPs covering the genome, no single SNP shows significant association with ASD or selected phenotypes at a genome-wide level. The SNP that achieves the smallest P-value from secondary analyses is rs1718101. It falls in CNTNAP2, a gene previously implicated in susceptibility for ASD. This SNP also shows modest association with age of word/phrase acquisition in ASD subjects, of interest because features of language development are also associated with other variation in CNTNAP2. In contrast, allele scores derived from the transmission of common alleles to Stage 1 cases significantly predict case status in the independent Stage 2 sample. Despite being significant, the variance explained by these allele scores was small (Vm< 1%). Based on results from individual SNPs and their en masse effect on risk, as inferred from the allele score results, it is reasonable to conclude that common variants affect the risk for ASD but their individual effects are modest
