Restoring Fort Frontenac In 3d: Effective Usage Of 3d Technology For Heritage Visualization, Mitsuyoshi Yabe

Theses

My thesis is composed of three elements: 3D modeling, web design, and heritage visualization. My goal is to use computer graphics design to inform and create an interest in historical visualization by rebuilding Fort Frontenac using 3D modeling and interactive design. The final model will be integrated into an interactive website to learn more about the fort's historic importance. It is apparent that using computer graphics can save time and money when it comes to historical visualization. Visitors do not have to travel to the actual archaeological buildings. They can simply use the Web in their own home to learn …

Alaska Athabascan Stellar Astronomy, Christopher M. Cannon

Arctic and Northern Studies

Stellar astronomy is a fundamental component of Alaska Athabascan cultures that facilitates time-reckoning, navigation, weather forecasting, and cosmology. Evidence from the linguistic record suggests that a group of stars corresponding to the Big Dipper is the only widely attested constellation across the Northern Athabascan languages. However, instruction from expert Athabascan consultants shows that the correlation of these names with the Big Dipper is only partial. In Alaska Gwich'in, Ahtna, and Upper Tanana languages the Big Dipper is identified as one part of a much larger circumpolar humanoid constellation that spans more than 133 degrees across the sky. The Big Dipper …

Characterization Of The Adenosine A1 Receptor In Summer And Winter Arctic Ground Squirrels, Zachary A. Carlson

Chemistry and Biochemistry

Hibernation is an adaptation that allows the Arctic ground squirrel (Urocitellus parryii) to survive the harsh arctic winter. Recently the activation of the Adenosine A1 receptor (A₁AR) has been shown to be necessary for entrance into hibernation during the winter but not summer season. In the current study we characterize the A₁AR in the forebrain, hippocampus and hypothalamus of summer and winter AGS. We also tested the hypothesis that increased A₁AR agonist efficacy is responsible for increased sensitization of the A₁AR during the winter season. The resulting ³⁵S-GTPγS binding data indicated an increase in agonist potency during the winter season …

Publications and Research

Introduction Epigallocatechin 3-gallate (EGCG), a polyphenol present in green tea, was shown to exert chondroprotective effects in vitro. In this study, we used a posttraumatic osteoarthritis (OA) mouse model to test whether EGCG could slow the progression of OA and relieve OA-associated pain. Methods C57BL/6 mice were subjected to surgical destabilization of the medial meniscus (DMM) or sham surgery. EGCG (25 mg/kg) or vehicle control was administered daily for 4 or 8 weeks by intraperitoneal injection starting on the day of surgery. OA severity was evaluated using Safranin O staining and Osteoarthritis Research Society International (OARSI) scores, as well as …

Parasites And Skeletal Indicators Of Anemia In The Eastern United States, Erin Dinneen

Anthropology

The goal of this research is to examine the influence of parasitic infection and diet in the etiology of anemia in prehistoric human populations of the eastern United States. Prehistorically, anemia is often attributed to a nutrient-deficient diet, while parasite infection is discussed as a secondary cause if at all. However, parasite infection is a leading cause of anemia in the developing world today. Modern epidemiological studies have demonstrated that parasites thrive or perish under particular environmental conditions, and risk for parasite infection can be predicted based on environment using GIS. Here I apply this method to see whether environmental …

Honda Country: Relocalization Through Technology In Nanwalek Alaska, David Dehass

Indigenous Studies

It should not be assumed that the introduction of a new technology automatically wipes out past cultural practices. Instead, it is often the case that these offerings are integrated into a current routine. For the Sugpiat of Nanwalek, Alaska, there is a constant need to negotiate between what to change and what to preserve. My research explores how a cultural group judges a new technology based upon shared boundaries and understandings. I examine how the decision to accept all-terrain vehicles (ATVs) has allowed for increased participation in subsistence practices, effective resource management, and material and emotional reunification with those things …

Growth And Maturity Of The Pacific Razor Clam In Eastern Cook Inlet, Alaska, Jamie M. Mckellar

Fisheries

In Alaska, the only road-accessible fishery for the Pacific razor clam, Siliqua patula, is located in eastern Cook Inlet, and has been monitored by the Alaska Department of Fish & Game (ADF&G) since 1964. In recent years, a shift has been observed in size, age, and number of clam cohorts in this region, yet little is known about the early life history of razor clams in this region. This study aimed to provide information on length and age at maturity, growth rates, and spawn timing at two beaches in eastern Cook Inlet, Ninilchik and Clam Gulch, in 2009 and 2010. …

Feeding Ecology And Movement Patterns Of Juvenile Sablefish In Coastal Southeast Alaska, Karson Marie Coutré

Fisheries

Sablefish, Anoplopoma fimbria, is a commercially valuable groundfish species undergoing population declines in the Gulf of Alaska and Bering Sea. This study assessed the role of juvenile sablefish as consumers in coastal Southeast Alaska (St. John Baptist Bay, Baranof Island, Alaska; SJBB) to better understand their use of habitat and food resources during their early life history. Specifically, the diet of juvenile sablefish was described for multiple seasons (summer and fall) and years (2012 and 2013) from analysis of stomach contents recovered using gastric lavage. Sablefish ate a wide variety of prey taxa, and the most important prey groups were …

Biotic And Abiotic Influences On The Use Of Arctic Lakes By Fish And Loons, Trevor B. Haynes

Fisheries

The particularly severe effects of climate change anticipated in the Arctic, accompanied by ongoing anthropogenic activities, necessitate proactive and knowledge-based management of the region's aquatic ecosystems. However, the paucity of information on the Arctic's aquatic environments hinders strategic or spatially-explicit management. In this dissertation, I examine the habitat use of poorly studied taxa of the Arctic Coastal Plain (ACP) of Alaska, including freshwater fishes and yellow-billed loons (Gavia adamsii). Distribution studies can be biased by false absences; therefore, I began by determining the detection probabilities of six fish species common to Arctic lakes for five gear types (Chapter 2). Variation …

The Effects Of Barotrauma And Deepwater-Release Mechanisms On The Reproductive Viability Of Yelloweye Rockfish In Prince William Sound, Alaska, Brittany Blain

Fisheries

Previous research has shown that releasing sport-caught Yelloweye Rockfish Sebastes ruberrimus with a deepwater-release mechanism (DRM) can alleviate anatomical damage due to barotrauma. However, it is unknown if a Yelloweye Rockfish remains a viable member of the population and reproduces in subsequent years following a barotrauma event and recompression with a DRM. The objectives of my study were to: 1) determine if Yelloweye Rockfish were able to reproduce one to two years following known forced decompression and recompression event(s); and 2) evaluate if barotrauma and recompression affected the quality of developing embryos. In 2010, Yelloweye Rockfish were sampled from an …

Variability In Foraging By Humpback Whales (Megaptera Novaenangliae) On The Kodiak, Ak, Feeding Ground, Dana Louise Wright

Marine Biology

The North Pacific humpback whale (Megaptera novaeangliae) population has been growing rapidly following a moratorium on commercial whaling in 1986. Knowledge of humpback whale foraging on feeding grounds is becoming increasingly important as the growing population consumes more prey, including economically important commercial fishes. The goal of this thesis is to better understand how marine resources are shared among the growing humpback whale population and sympatric apex predators, including western Steller sea lions (SSLs; Eumetopias jubatus), on the Kodiak, AK, feeding ground. To address this, we explored spatial and temporal (inter-annual and within-feeding season) variability in summer foraging by humpback …

Host Genetics And Diet, But Not Immunoglobulin A Expression, Converge To Shape Compositional Features Of The Gut Microbiome In An Advanced Intercross Population Of Mice, Larry J. Leamy, Scott A. Kelly, Joseph Nietfeldt, Ryan M. Legge, Fangrui Ma, Kunjie Hua, Rohita Sinha, Daniel A. Peterson, Jens Walter, Andrew K. Benson, Daniel Pomp

Department of Food Science and Technology: Faculty Publications

Background: Individuality in the species composition of the vertebrate gut microbiota is driven by a combination of host and environmental factors that have largely been studied independently. We studied the convergence of these factors in a G₁₀ mouse population generated from a cross between two strains to search for quantitative trait loci (QTLs) that affect gut microbiota composition or ileal Immunoglobulin A (IgA) expression in mice fed normal or high-fat diets.

Results: We found 42 microbiota-specific QTLs in 27 different genomic regions that affect the relative abundances of 39 taxa, including four QTL that were shared between this G …

Fap206 Is A Microtubule-Docking Adapter For Ciliary Radial Spoke 2 And Dynein C, Krishna K. Vasudevan, Kangkang Song, Lea M. Alford, Winfield Sale, Erin E. Dymek, Elizabeth F. Smith, Todd Hennessey, Ewa Joachimiak, Paulina Urbanska, Dorota Wloga, William Dentler, Daniela Nicastro, Jacek Gaertig

Dartmouth Scholarship

Radial spokes are conserved macromolecular complexes that are essential for ciliary motility. A triplet of three radial spokes, RS1, RS2, and RS3, repeats every 96 nm along the doublet microtubules. Each spoke has a distinct base that docks to the doublet and is linked to different inner dynein arms. Little is known about the assembly and functions of individual radial spokes. A knockout of the conserved ciliary protein FAP206 in the ciliate Tetrahymena resulted in slow cell motility. Cryo–electron tomography showed that in the absence of FAP206, the 96-nm repeats lacked RS2 and dynein c. Occasionally, RS2 assembled but lacked …

Alaska Native Perceptions Of Food, Health, And Community Well-Being: Challenging Nutritional Colonialism, Melanie Lindholm

Arctic and Northern Studies

Alaska Native populations have undergone relatively rapid changes in nearly every aspect of life over the past half century. Overall lifestyles have shifted from subsistence-based to wage-based, from traditional to Western, and from self-sustainability to reliance on Outside sources. My research investigates the effects of these changes on health and well-being. The literature appears to lack concern for and documentation of Native peoples' perceptions of the changes in food systems and effects on their communities. Additionally, there is a lack of studies specific to Alaska Native individual perceptions of health and well-being. Therefore, my research aims to help identify social …

The Integrated Hydrologic And Societal Impacts Of A Warming Climate In Interior Alaska, Charles E. Jones

Engineering

In this dissertation, interdisciplinary research methods were used to examine how changes in hydrology associated with climate affect Alaskans. Partnerships were established with residents of Fairbanks and Tanana to develop scientific investigations relevant to rural Alaskans. In chapter 2, local knowledge was incorporated into scientific models to identify a socialecological threshold used to model potential driftwood harvest from the Yukon River. Anecdotal evidence and subsistence calendar records were combined with scientific data to model the harvest rates of driftwood. Modeling results estimate that between 1980 and 2010 hydrologic factors alone were responsible for a 29% decrease in the annual wood …

Effect Of Allyl Isothiocyanate On Developmental Toxicity In Exposed Xenopus Laevis Embryos, John Russell Williams, James R. Rayburn, George R. Cline, Roger Sauterer, Mendel Friedman

Research, Publications & Creative Work

The pungent natural compound allyl isothiocyanate isolated from the seeds of Cru-ciferous (Brassica) plants such as mustard is reported to exhibit numerous beneficialhealth-promoting antimicrobial, antifungal, anticarcinogenic, cardioprotective, and neu-roprotective properties. Because it is also reported to damage DNA and is toxic to aquaticorganisms, the objective of the present study was to determine whether it possesses tera-togenic properties. The frog embryo teratogenesis assay-Xenopus (FETAX) was used todetermine the following measures of developmental toxicity of the allyl isothiocyanate:(a) 96-h LC50, defined as the median concentration causing 50% embryo lethality; (b) 96-h EC50, defined as the median concentration causing 50% malformations of the …

Trophic Dynamics In A Changing Arctic: Interactions Between Ptarmigan And Willows In Northern Alaska, Katie Christie

Biological Sciences

Shrubs have been expanding in the Arctic over the past century, with important consequences for ecosystem functioning, plant community composition, and wildlife habitat. Herbivores have the capacity to strongly moderate the growth and biomass of shrubs, and therefore need to be considered when attempting to understand and project future changes to Arctic ecosystems. Ptarmigan (Lagopus lagopus, L. muta) are common and widespread in many tundra regions, and feed on shrubs throughout their life cycle. Ptarmigan are likely to be an important herbivore in northern Alaska where shrub expansion is rapidly occurring; however, little is known about their spatial and temporal …

Infection Rates, Parasitemia Levels, And Genetic Diversity Of Hematozoa In New World Waterfowl, Matthew M. Smith

Biological Sciences

Blood parasites can limit the productivity of birds and increase the vulnerability of isolated and naïve populations to extinction. I examined 804 blood samples collected from 11 species of South American waterfowl to assess infection by Haemoproteus, Plasmodium and/or Leucocytozoon parasites. In addition, I strove to develop a new molecular tool to quickly and accurately determine relative parasitemia rates of Leucocytozoon parasites in avian blood. I used samples collected from waterfowl in interior Alaska (n = 105) to develop and optimize a real-time, quantitative PCR methodology using TaqMan fluorogenic probes. Molecular screening produced an apparent prevalence rate of 3.1% for …

Effects Of Snowmobile Noise And Activity On A Boreal Ecosystem In Southcentral Alaska, Timothy Carl Mullet

Biological Sciences

Snowmobiling is a popular winter activity in northern regions of North America. Although snowmobiles are important utility vehicles and serve as a means of outdoor recreation, their activity is known to affect plants and animals. These effects have been a growing concern over the past 20 years as a result of increased snowmobile activity into once inaccessible natural areas. Minimizing the impacts of snowmobiles on biota, preserving the quality and character of wilderness areas, and providing adequate access to snowmobilers for traditional activities has been a challenge for public land managers in Alaska. To address the effects that snowmobiles have …

Monitoring Energy And Nitrogen Availability For Arctic Caribou (Rangifer Tarandus), Lindsay L. Vansomeren

Biological Sciences

Arctic caribou and reindeer (Rangifer tarandus) are an economically and ecologically important species. Rangifer populations are often affected by nutritional factors. Our ability to monitor nutrient supply to arctic ungulates is presently limited by a lack of techniques to consistently and easily measure availability of specific nutrients and which may disproportionately affect different segments of Rangifer populations. I refined and validated a method to measure availability of specific nutrients including nitrogen (N) and energy to caribou using purified fibrolytic enzymes and acid/pepsin to simulate digestion. I then used this method to measure how availability of nitrogen and energy was altered …

Effect Of Temperature On The Phenology Of Chilo Partellus (Swinhoe) (Lepidoptera, Crambidae); Simulation And Visualization Of The Potential Future Distribution Of C. Partellus In Africa Under Warmer Temperatures Through The Development Of Life-Table Parameters, N. Khadioli, Z. E.H. Tonnang, E. Muchugu, G. Ong'amo, T. Achia, I. Kipchirchir, J. Kroschel, B. Le Ru

All Peer-Reviewed Publications

Maize (Zea mays) is a major staple food in Africa. However, maize production is severely reduced by damage caused by feeding lepidopteran pests. In East and Southern Africa, Chilo partellus is one of the most damaging cereal stem borers mainly found in the warmer lowland areas. In this study, it was hypothesized that the future distribution and abundance of C. partellus may be affected greatly by the current global warming. The temperature-dependent population growth potential of C. partellus was studied on artificial diet under laboratory conditions at six constant temperatures (15, 18, 20, 25, 28, 30, 32 and 35 °C), …

Research And Inhabited Image (Ria): A Spatial Hypothesis, Sveva Avveduto, Fabio Fornasari

The Transdisciplinary STEAM+ Journal

This paper discusses the possibility of representing research activity as a narrative path starting from an experimentation field. The aim is to test and verify connections between social space and the construction of images of the world through the building and perception of specific language in the narrative dimension of research. The field work we present has been carried out as an installation art in Borromini’s Crypt in Rome, and is the example of rendering the story-dimension of research through a medium, a narrative technology in constant progress and evolution. In this way research activity can be presented as ascent …

The Return On Investment For Undergraduate Degrees In Hospitality And Tourism Management, Asli D. Tasci, Abraham Pizam, Robertico Croes, Po-Ju Chen

Rosen Faculty Scholarship and Creative Works

Increasing concerns regarding the value of higher education in the USA have motivated several organizations to calculate the return on investment (ROI) for college education by employing diverse methodologies. This study evaluates these methodologies by using data from a survey of alumni of Rosen College of Hospitality Management at the University of Central Florida. The results reveal that the highly publicized low ROI for college education might be inaccurate, confusing and misleading for several reasons, among which is the assumption of zero income while studying, causing debt to be the total of a student’s expenses. Data reveal that Rosen College …
