Factors Influencing Distribution Of Prosthetic Devices In Iran: An Economic Analysis, Sarah Tensen

Virginias Collegiate Honors Council Conference

An estimated 177,622 Iranians have suffered an injury resulting in amputation. Prosthetic devices in Iran are scarce due to wealth disparity, wars, and lack of vital resources. Without prosthetic devices, amputees face unemployment, homelessness, a lowered self-esteem and cannot fully participate in society. I examined economic factors influencing the distribution of prosthetic devices and reviewed articles that focus on healthcare costs, distributions and services, relationships between Iran and other countries, etiology of amputation to find a solution for the prosthetic distribution issues. I concluded issues resulted from high costs, unequal distributions of wealth and resources, unsafe conditions, and a deficit …

Ultramafic Geoecology Of South And Southeast Asia, M.L. Galey, A. Van Der Ent, M.C.M. Iqbal, N. Rajakaruna

Biological Sciences

Globally, ultramafic outcrops are renowned for hosting foras with high levels of endemism, including plants with specialised adaptations such as nickel or manganese hyperaccumulation. Soils derived from ultramafic regoliths are generally nutrient-deficient, have major cation imbalances, and have concomitant high concentrations of potentially phytotoxic trace elements, especially nickel. The South and Southeast Asian region has the largest surface occurrences of ultramafic regoliths in the world, but the geoecology of these outcrops is still poorly studied despite severe conservation threats. Due to the paucity of systematic plant collections in many areas and the lack of georeferenced herbarium records and databased information, …

Dental Workforce Availability And Dental Services Utilization In Appalachia: A Geospatial Analysis, Xue Feng, Usha Sambamoorthi, R. Constance Wiener

Clinical and Translational Science Institute

Objectives—There is considerable variation in dental services utilization across Appalachian counties, and a plausible explanation is that individuals in some geographical areas do not utilize dental care due to dental workforce shortage. We conducted an ecological study on dental workforce availability and dental services utilization in Appalachia. Methods—We derived county-level (n = 364) data on demographic, socio-economic characteristics and dental services utilization in Appalachia from the 2010 Behavioral Risk Factor Surveillance System (BRFSS) using person-level data. We obtained county-level dental workforce availability and physician-to-population ratio estimates from Area Health Resource File, and linked them to the county-level BRFSS data. The …

The Alpine Vascular Plants Of Baxter State Park, Maine, Usa, Abigail J. Urban, Glen H. Mittelhauser, Matthew Dickinson, N. Rajakaruna

Biological Sciences

We conducted 12 days of field surveys on five mountains over 1100 m in elevation (Katahdin, North Brother, South Brother, Mount Coe, and The Owl) in Baxter State Park (BSP), Maine during the summers of 2013–14. In addition, we examined historic manuscripts, unpublished data, and herbarium records for plant records from the five mountains. Katahdin, the largest and tallest of the five mountains, has a rich history of botanical exploration and we documented 1559 herbarium vouchers that were collected from the mountain, primarily before the mid-1900s. Combining all data sources, we documented 38 families, 87 genera, and 131 taxa of …

Decadal Vegetation Succession Along A Chronosequence Within Eucalyptus Obliqua Wet Forest, Southern Tasmania, Christine Dobbin

Independent Study Project (ISP) Collection

Southern Tasmania is home to fire dependent mixed forests, which, if not maintained, will eventually be replaced by the rainforest understorey. Wet eucalypt forest succession after disturbance events was investigated through floristic and vertical measurements of four north facing chronosequence plots with labels describing the age class of each, from regrowth to mature sites. This study was possible due to the establishment of permanent 50m x 50m plots in 2007 for longitudinal monitoring and subsequent illustration of forest dynamics following disturbance, including clearfell burns and wildfire. The contents of this report are the comparative analyses of the findings from the …

The Sacred Forest And The Mythical Python: Ecology, Conservation, And Sustainability In Kom, Cameroon, C. 1700-2000, Walter Gam Nkwi Dr

Journal of Global Initiatives: Policy, Pedagogy, Perspective

Scholars have taken a keen interest in the social and cultural meanings of the African landscape in the reconstruction of the continent’s history (Giblin, 1992; Spear, 1997; Wagner, 1995). But how much did Africans know of their environmental past? This article explores the indigenous history of ecology, focusing on the medicinal forest (ak’u mii-fii) and the mythical python (iigw-im) and their link with livelihood and sustainability in Kom, Cameroon. The paper argues that the Kom people have always been conserving their forests since the pre-colonial era. During the colonial period and especially in the 1930s many hectares of land including …

Ebola Virus - Epidemiology, Diagnosis, And Control: Threat To Humans, Lessons Learnt, And Preparedness Plans - An Update On Its 40 Year's Journey, Raj Kumar Singh, Kuldeep Dhama, Yashpal Singh Malik, Muthannan Andavar Ramakrishnan, Kumaragurubaran Karthik, Rekha Khandia, Ruchi Tiwari, Ashok Munjal, Mani Saminathan, Perumal Arumugam, Sunil Kumar Joshi

Bioelectrics Publications

Ebola virus (EBOV) is an extremely contagious pathogen and causes lethal hemorrhagic fever disease in man and animals. The recently occurred Ebola virus disease (EVD) outbreaks in the West African countries have categorized it as an international health concern. For the virus maintenance and transmission, the non-human primates and reservoir hosts like fruit bats have played a vital role. For curbing the disease timely, we need effective therapeutics/prophylactics, however, in the absence of any approved vaccine, timely diagnosis and monitoring of EBOV remains of utmost importance. The technologically advanced vaccines like a viral-vectored vaccine, DNA vaccine and virus-like particles are …

Habitat Use And Behaviours Of Introduced Muscovy Ducks (Cairina Moschata) In Urban And Suburban Environments, Joni Downs, Rebecca Loraamm, James Howard Anderson Jr., Jacqueline Perry, Jessica Bullock

Suburban Sustainability

Muscovy ducks (Cairina moschata) are native to South America, Central America, and Mexico. The species is commonly domesticated and raised for meat across the globe. Escaped or intentionally introduced populations have become established in many suburban areas, although they are little studied. A total of 642 individual time-activity budgets were collected for invasive Muscovy ducks in Tampa, Florida, USA, in order to quantify habitat use and behavioural patterns. Muscovy ducks utilized a variety of cover types, including open water, shoreline, grass, tree, shrub, and urban habitats. Muscovy ducks foraged by dabbling, gleaning, grazing, and probing, while occasionally obtaining, …

Abundance And Habitat Preferences Of Introduced Muscovy Ducks (Cairina Moschata), Jacqueline Marie Perry Cahanin

USF Tampa Graduate Theses and Dissertations

Muscovy ducks are native only to Central and South America, Mexico, and parts of southern Texas and are considered invasive in some areas outside of their native range. Although they have been introduced worldwide, they remain largely unstudied. The primary focus of this study was to relate Muscovy duck abundance to habitat characteristics of wetlands in Tampa, Florida. Muscovy abundance was measured using point count methods at 21 wetland sites that occur within an eight km radius of the University of South Florida’s main campus. Habitat features at these sites were assessed using field methods and Geographic Information Systems (GIS) …

Zonation Pattern And Spatial Arrangement Of A Geukensia Granosissima Population In A Mixed Mangrove Forest Of Tampa Bay, Derrick Shane Hudson

USF Tampa Graduate Theses and Dissertations

Here I provide the first report on Geukensia granosissima patterns of abundance along a tidal gradient within a mixed mangrove stand located in Tampa Bay, Florida, USA. Specifically, I examined 1) the relationship between G. granosissima size and density with mangrove root type (e.g. prop root, pneumatophore), and of density within the intertidal zones; and 2) the possible role of predation in shaping the lower zonation patterns displayed. Transect surveys located along the lower and upper population limit boundaries were conducted every two months over a ten-month period. Variables measured include size distribution, density of mussels, above ground mangrove prop …

Geographical Information Systems (Gis) Applied To Urban Nutrient Management: Data Scarce Case Studies From Belize And Florida, Charlotte Juliane Haberstroh

USF Tampa Graduate Theses and Dissertations

Nutrient inputs into the environment greatly impact urban ecosystems. Appropriate management strategies are needed to limit eutrophication of surface water bodies and contamination of groundwater. In many existing urban environments, retrofits or complete upgrades are needed for stormwater and/or wastewater infrastructure to manage nutrients. However, sustainable urban nutrient management requires comprehensive baseline data that is often not available. A Framework for Urban Nutrient (FUN) Management for Geographic Information Systems (GIS) was developed to specifically address those areas with limited data access. Using spatial analysis in GIS, it links water quality, land use, and socio-demographics, thereby reducing data collection and field-based …

Wildland Resources Faculty Publications

The occurrence of wildfire is influenced by a suite of factors ranging from “top-down” influences (e.g., climate) to “bottom-up” localized influences (e.g., ignitions, fuels, and land use). We carried out the first broad-scale assessment of wildland fire patterns in northern Mexico to assess the relative influence of top-down and bottom-up drivers of fire in a region where frequent fire regimes continued well into the 20th century. Using a network of 67 sites, we assessed (1) fire synchrony and the scales at which synchrony is evident, (2) climate drivers of fire, and (3) asynchrony in fire regime changes. We found high …

Ecological Correlations Of Dietary Food Intake And Mental Health Disorders, Jordan Hoerr, Joshua Fogel, Benjamin Van Voorhees

Publications and Research

This paper examines the ecological association of dietary food intake with mental health outcomes on the group level across countries. Published data from the World Mental Health Survey were used to compare lifetime prevalence of four categories of mental health disorders (anxiety disorders, mood disorders, impulse control disorders, and substance use disorders) with a country’s fish/seafood and sugar/sweetener supply quantity using the Spearman rank correlation. Data were compared for 17 countries across the world. Sugar and sweetener supply quantity was significantly and positively associated with anxiety disorders (rho = 0.75, p = 0.001), mood disorders (rho = 0.75, p = …

Using Ranked Auxiliary Covariate As A More Efficient Sampling Design For Ancova Model: Analysis Of A Psychological Intervention To Buttress Resilience, Rajai Jabrah, Hani Samawi, Robert Vogel, Haresh Rochani, Daniel Linder

Biostatistics: Faculty Publications

Drawing a sample can be costly or time consuming in some studies. However, it may be possible to rank the sampling units according to some baseline auxiliary covariates, which are easily obtainable, and/or cost efficient. Ranked set sampling (RSS) is a method to achieve this goal. In this paper, we propose a modified approach of the RSS method to allocate units into an experimental study that compares L groups. Computer simulation estimates the empirical nominal values and the empirical power values for the test procedure of comparing L different groups using modified RSS based on the regression approach in analysis …

Polytechnic Journal

Heavy trace metals such as arsenic, cobalt, chromium, nickel, cadmium, mercury, selenium and lead, in addition to some micronutrients such as manganese, copper, iron and zinc were analyzed in water, sediment, and tissues of three edible fishes (Capoeta trutta, Arabibarbus grypus, Cyprinus carpio) and two gull species (Chroicocephalus genei and Larus michahellis) from Derbendikhan Lake in Sulaymaniyah governorate, Kurdistan region of Iraq during winter, spring and summer seasons. The content of heavy metals in the fish species differed depending on the season, feeding status and sediment quality which in turn biomagnified in gull tissues. The indices of bioaccumulation factors from …

Gait Changes In A Line Of Mice Artificially Selected For Longer Limbs, Leah M. Sparrow, Emily Pellattt, Sabrina S. Yu, David A. Raichlen, Herman Pontzer, Campbell Rolian

Publications and Research

In legged terrestrial locomotion, the duration of stance phase, i.e., when limbs are in contact with the substrate, is positively correlated with limb length, and negatively correlated with the metabolic cost of transport. These relationships are well documented at the interspecific level, across a broad range of body sizes and travel speeds. However, such relationships are harder to evaluate within species (i.e., where natural selection operates), largely for practical reasons, including low population variance in limb length, and the presence of confounding factors such as body mass, or training. Here, we compared spatiotemporal kinematics of gait in Longshanks, a long-legged …
