“Reds Driven Off”: the US Media’s Propaganda During the Gulf of Tonkin Incident
In 2008, the Annenburg Public Policy Center of the University of Pennsylvania conducted a poll to determine just how informed voters were following that year’s presidential election. One of the most shocking things they found was that 46.4% of those polled still believed that Saddam Hussein played a role in the terrorist attacks on the US on September 11th, 2001. No evidence had ever emerged linking him to it after 5 years of war in Iraq, but that did not matter, as “voters, once deceived, tend to stay that way despite all evidence.” Botched initial reporting can permanently entrench false information into the public’s mind and influence them to come to faulty conclusions as a result. This power of first impressions gives journalists an immense and solemn responsibility when conveying events. A misleading headline or an unsubstantiated report can sway the public towards similarly flawed conclusions with disastrous results
Be Good: Hatred and Hope in the Letters of Gerald Koster
To tell an informative story about someone’s life is difficult at the best of times. Gerald “Gerry” Koster’s correspondence during his last year of service in the US Navy towards the end of the Pacific War can thus only paint an incomplete portrait of who he was and what exactly the war meant to him. Nevertheless, there are things that his letters can teach readers, not only about Koster’s role and daily activities in the military, but about his personal character and how that manifested in his interactions with the defeated Japanese and his family. And perhaps, through his personal character, it is possible to discern something larger about the culture of his specific time and place in history
An automated tool for the design and assessment of space systems
Space systems can be characterized as both large and complex but they often rely on reusable subcomponents. One problem in the design of such systems is the representation and validation of the system, particularly at the higher levels of management. An automated tool is described for the representation, refinement, and validation of such complex systems based on a formal design theory, the Theory of Plausible Design. In particular, the steps necessary to automate the tool and make it a competent, usable assistant, are described
Are there Carbon Savings from US Biofuel Policies? Accounting for Leakage in Land and Fuel Markets
This paper applies the insights of the carbon leakage literature to study the emissions consequences of biofuel policies. We develop a simple analytic framework to decompose the intended emissions impacts of biofuel policy from four sources of carbon leakage: domestic fuel markets, domestic land markets, world land markets and world crude oil markets. A numerical simulation model illustrates the magnitude of each source of leakage for combinations of two current US biofuel policies: the Volumetric Ethanol Excise Tax Credit (VEETC) and the Renewable Fuel Standard (RFS). In the presence of both land and fuel market leakage, current US biofuel policies are unlikely to reduce greenhouse gases. Four of the five policy scenarios we consider lead to increases in greenhouse gas emissions. That is, total leakage was greater than 100%. The single scenario that generates emissions savings, the removal of the VEETC in conjunction with a binding RFS, only does so because negative leakage in the domestic fuel market offset the remaining positive sources of leakage.Multi-market, carbon leakage, biofuels, greenhouse gases, Agricultural and Food Policy, Land Economics/Use, Resource /Energy Economics and Policy, Q42, Q54, Q58,
Phonon Band Structure and Thermal Transport Correlation in a Layered Diatomic Crystal
To elucidate the relationship between a crystal's structure, its thermal
conductivity, and its phonon dispersion characteristics, an analysis is
conducted on layered diatomic Lennard-Jones crystals with various mass ratios.
Lattice dynamics theory and molecular dynamics simulations are used to predict
the phonon dispersion curves and the thermal conductivity. The layered
structure generates directionally dependent thermal conductivities lower than
those predicted by density trends alone. The dispersion characteristics are
quantified using a set of novel band diagram metrics, which are used to assess
the contributions of acoustic phonons and optical phonons to the thermal
conductivity. The thermal conductivity increases as the extent of the acoustic
modes increases, and decreases as the extent of the stop bands increases. The
sensitivity of the thermal conductivity to the band diagram metrics is highest
at low temperatures, where there is less anharmonic scattering, indicating that
dispersion plays a more prominent role in thermal transport in that regime. We
propose that the dispersion metrics (i) provide an indirect measure of the
relative contributions of dispersion and anharmonic scattering to the thermal
transport, and (ii) uncouple the standard thermal conductivity
structure-property relation to that of structure-dispersion and
dispersion-property relations, providing opportunities for better understanding
of the underlying physical mechanisms and a potential tool for material design.Comment: 30 pages, 10 figure

Dusky Grouse Population Ecology and Thermal Landscape Ecology in the Great Basin Ecosystem
Dusky Grouse are a mountainous forest grouse found throughout the western, inland mountain ranges of the United States and Canada. While a few studies have looked at Dusky Grouse in the Rocky Mountain Ecosystem of their range, there have been no prior studies of the Dusky Grouse in the Great Basin Ecosystem aside from a brief survey by Zwickel and Bendell in 2004 in the Duck Creek Range of Nevada. With the available habitats differing in both species diversity and availability on the landscape between the two Ecosystems, I wanted to assess characteristics about the Dusky Grouse populations at the southwestern edge of their range in the Great Basin Ecosystem. Thus, I estimated the abundance of Dusky Grouse in the Schell Creek, Duck Creek, and Egan Ranges of White Pine County, Nevada, as well as created a monitoring protocol for continued monitoring of abundance in these areas. I estimated a density of 5 males/km2. I also assessed the seasonal habitat selection of Dusky Grouse in the White Pine County study areas during breeding, nesting, brooding, and over winter. Dusky Grouse used aspen, conifers, and mountain shrubland habitat types the most across the seasons. Finally, I determined the varying temperatures of the study area’s landscape during peak summer and identified possible thermal refuge, or areas that protect species from extreme heat, for an array of wildlife taxa on the landscape. Aspen and conifer stands offered the coolest thermal refuge during peak hours of the summer compared to mountain mahogany, pinyon-juniper, and mountain shrublands. This research is new for the Great Basin Ecosystem, as well as for Dusky Grouse literature as a whole
