Nomenclature for the Upper Triassic and Lower Jurassic strata along the south flank of the Uinta Mountains has been somewhat confusing because of the position of the study area between southern Wyoming, where one set of names is used, and central/southern Utah where a different set of formation names is used. The Nugget Sandstone or Glen Canyon Sandstone of the eastern Uinta Mountains overlies the Upper Triassic Popo Agie or Chinle Formation. The nature of the contact between these two formations is unclear both in stratigraphic location and conformability. The Chinle Formation consists, in ascending order, of the Gartra Member, the purple unit, the ocher unit, and the upper red unit. The overlying Nugget Sandstone consists of two members, the lower Bell Springs Member and the overlying unnamed cross-bedded member, typically believed to be Navajo Sandstone equivalent. These two units of the Nugget Sandstone are thought to represent the Glen Canyon Group of the Colorado Plateau, although no obvious Wingate or Kayenta Formation equivalents have been recognized. The Bell Springs Member contains abundant fine-grained, ripple-laminated sandstones, red and green mudstones, occasional mudcracks and salt casts, evidence of burrowing and exposure, and some medium- to coarse-grained sandstones with small-scale (30-40 cm high) cross-beds. This member was deposited in a marine tidal flat environment, quite different from the mainly eolian environment of the rest of the Nugget Sandstone. The Bell Springs Member appears to be entirely Upper Triassic, based upon dinosaur tracks, while the upper windblown unit's age is unknown, but probably straddles the Triassic-Jurassic boundary. During mapping in the Donkey Flat, Steinaker Reservoir, Dry Fork, and Lake Mountain quadrangles, the Bell Springs Member of the Nugget Sandstone was mapped as a separate unit.

Sleeper populations are established populations of a non-native species whose population growth is limited by one or more abiotic or biotic conditions, such as climate change. While the northeastern US is predicted to be a hotspot for future invasions, identifying potential sleeper populations before they become invasive can inform proactive, climate-smart invasive species management. I focused on 169 introduced species that are established in one or more northeastern states. I used the Environmental Impact Classification for Alien Taxa (EICAT) framework to systematically identify and review the peer-reviewed literature for these candidate species to quantify their negative ecological and socioeconomic impacts. I identified 49 plants with ‘major’ impacts linked to the decline of multiple native species or loss of community diversity. Using high negative ecological impact, habitat suitability, and climate suitability as selection criteria, I highlight 37 species as high priority for management in the North Atlantic –Appalachian Region.

Thin fallout tuffs in the Duchesne River Formation in the Uinta Basin, Utah are evidence that volcanism was active in northern Nevada and Utah in the late Eocene. The Uinta Basin is a sedimentary basin that formed during the Laramide orogeny. Ponded lakes of various salinity filled and emptied and during the late Eocene the northern rim was dominated by a wetland/floodplain depositional setting. Most of the tuffs have rhyolitic mineral assemblages including quartz, biotite, sanidine, and allanite. Rhyolitic glass shards were also found in one of the ash beds. Biotite compositions have Fe/(Fe+Mg) ratios typical of calc-alkaline igneous rocks and clusters of biotite compositions suggest 3 or 4 volcanic events. Sanidine compositions from five samples grouped at Or73 and Or79. Only one sample had plagioclase with compositions ranging between An22 - An49. Some beds also contained accessory phases of titanite, apatite, and zircon. Whole rock compositions of the altered volcanic ash beds indicate these tuffs underwent post-emplacement argillic alteration, typical of a wetland/floodplain depositional setting. Immobile element ratios and abundances, such as Zr/Nb and Y are typical of a subduction zone tectonic setting and rhyolitic composition. 40Ar/39Ar ages constrain the timing of volcanism. One plagioclase and one sanidine separate from two different tuff beds yielded ages of 39.47 ± 0.16 Ma and 39.36± 0.15 Ma respectively. These dates, along with the compositional data seem to limit the eruptive source for these fallout tuffs to the northeast Nevada volcanic field. These new ages, along with previously published ages in the Bishop Conglomerate which unconformably overlies the Duchesne River Formation, constrain the timing of two uplift periods of the Uinta Mountains at 39 Ma and 34 Ma. Finally, the ages also date the fauna of the Duchesnean Land Mammal Age to be about 39.4 Ma as opposed to less precise earlier estimates that placed it between 42 and 33 Ma.

Over the past half century, the USDA Forest Service has increasingly faced diverse and often competing demands for forest resources, ranging from recreation, to ecosystem services, and timber supply. Building positive community-agency relationships has become increasingly important. Such relationships can improve community support for forest planning and management activities, ultimately making the agency more efficient and effective, while also providing economic and social benefit to local communities. The development of social capital may play an important role in promoting positive agency-community relationships. Broadly defined, the term refers to the social networks between individuals and groups that create a willingness and ability to act collectively toward a common goal. This study focuses on the impact that a partnership between the Colville National Forest and Northeast Washington Forestry Coalition has had on rural Northeast Washington communities. Overall, our study suggests the partnership has positively impacted networks among community members and networks between the community and the Forest Service. However, there is room for improvement. Many study participants were not familiar with important details about the Coalition's membership and objectives, or how its work may impact them or their community. Targeted outreach efforts will likely lead to greater support for the partnership. Such efforts could also strengthen networks among community members and community-agency networks as individuals learn how the partnership can benefit them and issues they care about. / Graduation date: 2012

This thesis aims to evaluate the impact of the Constitutional Fund for Financing the Northeast (FNE) in the state of Bahia and Pernambuco economies in the period 1989-2010. Objective accordingly verify the spatial and sectoral allocation of investment has contributed to a better geographical distribution of economic activity fulfilling their goals. Furthermore, analyzing their impact on the supply chain of these States, to establish whether the investments are distributed on a priority basis and estimate job creation based on RAIS data, checking the evolution of formal employment. For both our territorial clipping is based on a micro IBGE classification and our main database, in addition to sources already cited also includes management reports and data FNE kindly made available by the Ministry of National Integration (MI), in addition to data obtained from the publications of the Bank of Northeast Brazil (BNB). We conclude that although the FNE have considerable importance in the structuring of the northeastern economy and the states concerned, their actions were much more constrained by the logic of the market than by networking with a national regional development policy. However, there is an undeniable contribution to devolution of productive activities within the region, although this devolution is happening imperfectly and directed the few regions and even less complex sectors are the biggest beneficiaries. Finally, we conclude that the macroeconomic framework of the region and the states analyzed, although impacted by the FNE, still lacks a more fruitful role of the public sector on the articulation of a national development policy. / Esta dissertação tem como proposta avaliar o impacto do Fundo Constitucional de Financiamento do Nordeste (FNE) nas economias estaduais da Bahia e Pernambuco, no período entre 1989-2010. Objetiva nesse sentido verificar se a alocação espacial e setorial dos investimentos tem contribuído para uma melhor distribuição geográfica da atividade econômica cumprindo com seus objetivos. Além disso, analisar o impacto dos mesmos na cadeia produtiva desses Estados, averiguar se os investimentos estão distribuídos de forma prioritária e estimar a geração de empregos com base nos dados da RAIS, verificando a evolução do emprego formal. Para tanto o nosso recorte territorial é por microrregiões com base na classificação do IBGE e nossa principal base de dados, além das fontes já citadas compreende também os relatórios de gestão e dados do FNE disponibilizados gentilmente pelo Ministério da Integração Nacional (MI), além dos dados obtidos através das publicações do Banco do Nordeste do Brasil (BNB). Concluímos que embora os recursos do FNE tenham peso considerável na estruturação da economia nordestina e dos estados em questão, as suas ações foram muito mais condicionadas pela lógica do mercado do que pela articulação junto a uma política nacional de desenvolvimento regional. Entretanto, é inegável a sua contribuição para desconcentração das atividades produtivas dentro da região, ainda que esta desconcentração esteja acontecendo de forma imperfeita e direcionada à poucas regiões e ainda que setores menos complexos sejam os maiores beneficiados. Por fim, concluí-se que a estrutura macroeconômica da região e dos estados analisados, embora impactada pelo FNE, ainda carece de uma atuação mais profícua do setor público na articulação de uma política nacional de desenvolvimento.

Au cours du Sylvicole supérieur (1000-1500 AD), le secteur de l’embouchure du Saguenay aurait été exploité par des groupes Iroquoiens du Saint-Laurent en quête de ressources marines, et plus particulièrement du phoque. Ces groupes provenaient vraisemblablement de la région de Québec où se trouvaient leurs camps de base et auraient ainsi développé une forme d’adaptation aux ressources marines de l’estuaire, faisant d’eux les groupes iroquoiens les plus mobiles de toute la vallée du Saint-Laurent. Dans cette étude, nous proposons que l’exploitation des mammifères marins fût pratiquée en deux temps, d’abord au printemps, lors de courtes périodes par des contignents de chasseurs masculins attirés par le phoque du Groenland et puis en été, par des familles entières profitant de la présence de phoques gris et commun. Les pinnipèdes étaient probablement traqués sur la batture ou sur les glaces et abattus à la hache ou à l’arc et à la flèche. Puisque les résidus alimentaires retrouvés dans les vases de cuisson étaient surtout composés de poissons et de mammifères terrestres, il est supposé que des sous-produits de la chasse au phoque aient été rapportés dans la région de Québec et utilisés comme réserve de nourriture, comme matière première ou comme monnaie d’échange. Nous défendons également l’hypothèse que ces excursions dans l’estuaire n’étaient pas nécessairement liées à la précarité de l’agriculture dans la région de Québec puisque cette pratique aurait été adoptée tardivement, soit après 1300 AD et peut être même à partir de 1400 AD. Les données sont issues de six sites ayant fait l’objet de fouilles répartis sur une bande littorale de 40 km de longueur. Il s’agit des sites Ouellet (DaEk-6), Anse-aux-Pilotes IV (DbEj-7), Cap-de-Bon-Désir (109G), Site archéologique des Basques-de-l’Anse-à-la-Cave (DbEi-5), Pointe-à-Crapaud (DbEi-2) et Escoumins I (DcEi-1). / During the Late Woodland period (AD 1000-1500), the area of the mouth of the Saguenay River was exploited by groups of St. Lawrence Iroquoians in search of marine resources, especially seals. These groups probably originated from the Quebec City region where their villages and permanent settlements were and thus developed a form of adaptation to the marine resources of the Estuary, making them the most mobile Iroquoian group in the St. Lawrence Valley. In this study, we propose that the exploitation of marine mammals was practiced in two stages, first in the Spring, during short periods by male hunters attracted by Harp seals and then in summer, by whole families taking advantage of gray and common seals. Pinnipeds were probably hunted on the foreshore or on the ice pack, with an ax or bow and arrow. Since the dishes cooked in the vessels consisted mainly of fish and land mammals, it is assumed that seal by-products were brought back in the Quebec City region and used as supplies, as raw material or as goods to exchange. We also propose the hypothesis that these excursions into the Estuary were not necessarily related to the precariousness of agriculture in the region of Quebec, since this practice was adopted later, after AD 1300 and perhaps even after AD 1400. The data used in this thesis are derived mainly from six sites located on a coastal strip extending over nearly 40 km. These sites are Ouellet (DaEk-6), Anse-aux-Pilotes-IV (DbEj-7), Cap-de-Bon-Désir (109G), site archéologique des Basques-de-l'Anse-à-la-Cave (DbEi-5), Pointe-à-Crapaud (DbEi-2) and Escoumins I (DcEi-1).

Approved for public release, distribution is unlimited / North Korea's pursuit of nuclear weapons has shaken the foundations of U.S. policy in Northeast Asia. Because of North Korea's record of state-sponsored terrorism, illicit activities, human rights violations, arms sales, and fiery rhetoric, its development of operational nuclear weapons is deeply disturbing. Although most agree North Korea should not possess nuclear weapons, nobody has a solution. This thesis evaluates three U.S. policy options for North Korean nuclear weapons: incentive-based diplomacy, coercive diplomacy, or military force. It analyzes them according to four criteria: the impact on North Korea's nuclear weapons, the impact on its neighbors (China, Japan, and South Korea), U.S. policy costs, and the precedent for future proliferation. This thesis shows that diplomacy will fail to achieve U.S. objectives for three reasons: lack of trust, DPRK reluctance to permit transparency, and the difficulty of conducting multilateral coercive diplomacy. Ultimately, Deputy Secretary of State Richard Armitage's question must be answered: "What price is the United States willing to pay to disarm North Korean nuclear weapons?" If Washington is unwilling to back a threat of military force, it should not risk coercive diplomacy. Likewise, U.S. leaders may need to decide between maintaining the U.S.-ROK alliance and eliminating North Korean nuclear weapons. / Major, United States Air Force

Parmi la grande quantité de témoins culturels découverts sur le site Droulers/Tsiionhiakwatha (BgFn-1), la pierre taillée et polie forme un assemblage bien modeste. Les Iroquoiens de Droulers ont habité un village semi-permanent daté du Sylvicole supérieur, plus précisément entre l’an 1430 et 1500 ap. J.-C. Ils ont fabriqués des grattoirs, des pointes de flèches, des forets, des polissoirs et des meules à mains, en plus d’outils en quartz hyalin dont la fonction n’est pas bien définie. Parmi les 3595 objets lithiques, nous trouvons 18 outils et 1085 déchets de taille en cristal, ce qui représente près de 30% du total. Le quartz hyalin fut utilisé durant la préhistoire québécoise, mais jamais en aussi grande quantité que sur Droulers. Nous présentons la chaîne opératoire du quartz hyalin, de son extraction à son rejet sur les sites archéologiques. Nous explorons également son utilisation et sa symbolique chez les habitants du village Droulers, une enquête basée sur des données archéologiques et ethnographiques des Amérindiens actuels et de ceux de la période de Contact du nord-est de l’Amérique du nord. / Among the large number of artefacts found on the Droulers/Tsiionhiakwatha Iroquoian village (BgFn-1), the assemblage of stone tools is very small. The Iroquoians at Droulers produced scrapers, arrowheads, drills, whetstones and manos, and also shaped tools with crystal quartz. Among the 3595 lithic objects, we find 18 tools and 1085 pieces of debitage in crystal quartz, which compose over 30% of the total lithic assemblage. Cristal quartz was worked during Québec prehistory, but never to this extent. This thesis is about the chaîne opératoire of crystal quartz and its uses throughout prehistory of Québec and among prehistoric Iroquoians.
