The Centennial Academic Year

The curriculum at the US Naval War College has been in evolution throughout its first century

Nancy Hynes Duval: Florida\u27s First Lady, 1822-1834

The contributions of women to Florida history, and the details of their lives, have been sadly neglected by the state’s historians. Unfortunately, that fact particularly is applicable to the nineteenth century, when Florida developed political, social, and religious institutions and patterns that have continued to influence the state and its residents. Unless the individual left reminiscences, such as was the case with Ellen Call Long and Susan Bradford Eppes, or else attained national prominence, as did Rachel Jackson and Peggy Timberlake Eaton, the likelihood of our familiarity with them— despite their lifetime prominence and importance-is slim at best. One such almost-forgotten person is Nancy Hynes DuVal, wife of Governor William Pope DuVal

A Focus on the On-Scene Commander

What are the chances that an international crisis would escalate into war as a result of tactical interactions between on-scene naval forces executing orders from national leaders trying to manage the crisis? Since war between the United States and the Soviet Union did not break out as a result of the many crises of the Cold War, a quick answer might be, Escalation seems unlikely; at least it turned out that way. The question, however, deserves a more thoughtful answer

William Pope Duval: An Extraordinary Folklorist

William Pope Duval, who served four terms as territorial governor of Florida, was a natural storyteller.1 His tales were crafted and fabricated with so much skill that his listeners believed every word as the absolute truth. DuVal never hesitated to shade the truth or to embellish his stories so that they became fictionalized accounts bordering on the fringes of reality. He wove a web of drama as he spoke and completely captured the attention of his audience. The stations in life they, the members of his audience, occupied did not matter— raw frontiersmen, uneducated workingmen, intellectuals, literary geniuses, or sophisticated former royalty

Tectonic History of Midcontinental United States

Metasediments of Middle Precambrian, and possibly some of earlier age, form an arcuate trending belt across Missouri, Kansas, and Nebraska. These were intruded by granites of several ages that appear to be part of a continuous wave of Late Precambrfan igneous activity. Late Precambrian events that can be delineated include, besides the igneous activity and formation of iron deposits, development of a Keweenawan basin that extended from Lake Superior into eastern Kansas; igneous activity and metamorphism of Grenville age in the eastern Midcontinent; development of a major fault lineament extending northeastward from northeast Arkansas into the Canadian shield outcrop area and separating basement rocks of two distinct ages; and a long period of uplift and erosion during which sediments were deposited in interior and fringing basins. A belt of volcanic rock, partly preserved as an erosional remnant, extended from Ohio into New Mexico and formed a continental divide during Late Precambrian and Early and Middle Cambrian time. Higher peaks in this belt form the present St. Francois, Eminence, and Spavinaw outcrop areas. This area of high volcanic rock is termed the “Ancestral Ozarks.” Paleozoic time was a transition from a positive to a negative to a stable area. It began with broad submergence followed by development of domes, arches, and basins. Continued development of lesser arches fragmented the Midcontinent into numerous small basins and highs. The final stage of activity, oscillation and accompanying cyclical sedimentation, was succeeded by stability. Numerous cryptoexplosion structures are known in the Midcontinent. Some are associated with intrusive and extrusive igneous activity. Nearly all of them lie on a preexisting structural axis

Synthesis, structure, and high-temperature thermoelectric properties of boron-doped Ba_8Al_(14)Si_(31) clathrate I phases

Single crystals of boron-doped Ba_8Al_(14)Si_(31) clathrate I phase were prepared using Al flux growth. The structure and elemental composition of the samples were characterized by single-crystal and powder X-ray diffraction; elemental analysis; and multinuclear ^(27)Al, ^(11)B, and ^(29)Si solid-state NMR. The samples' compositions of Ba_8B_(0.17)Al_(14)Si_(31), Ba_8B_(0.19)Al_(15)Si_(31), and Ba_8B_(0.32)Al_(14)Si_(310) were consistent with the framework-deficient clathrate I structure Ba_8Al_xSi_(42-3/4x)□_(4-1/4x) (X = 14, □ = lattice defect). Solid-state NMR provides further evidence for boron doped into the framework structure. Temperature-dependent resistivity indicates metallic behavior, and the negative Seebeck coefficient indicates that transport processes are dominated by electrons. Thermal conductivity is low, but not significantly lower than that observed in the undoped Ba_8Al_(14)Si_(31) prepared in the same manner
