Does The Foreign Direct Investment In Emerging Asian Countries Get ‘Greased’ Or ‘Sanded’ By Corruption? Evidence From Gets Model, Rainah Ginsad, Imbarine Bujang, Abdul Aziz Karia, Emelia Girau, Siti Rahayu Beli
ASEAN Journal on Science and Technology for Development
Inflows of foreign direct investment (FDI) considerably boost industrialization and economic growth in emerging economies. Corruption, human capital, and the economic environment are just a few factors mentioned in the literature as influencing FDI inflow. The impact of corruption on FDI, whether FDI is greased or sanded by corruption, has received greater interest in recent empirical study. This study analysed the impact of the Corruption Perception Index (CPI) on foreign direct investment (FDI) in selected Asian emerging economies. Utilising annual panel data covering 22 selected Asian emerging economies, this study uses the General-to-specific (GETS) model to analyse the impact. The …

Phylogenetic Relationships Of A North American Radiation Of Clematis (Ranunculaceae), Jesse Harris, Thomas H. Murphy, Erin A. Manzitto-Tripp, Nicolás Medina, Zach Irick, L. Dwayne Estes, Stacey D. Smith
Aliso: A Journal of Systematic and Floristic Botany
Clematis L. is one of many plant genera that contributes prominently to the species richness and endemism of the southeastern United States. Here we examined phylogenetic relationships among species in Clematis sect. Viorna, commonly known as leatherflowers, which are distributed primarily in the southeastern United States. We used data from restriction site-associated ddRADseq to reconstruct a best estimate phylogeny of this group. Our analyses revealed that the North American members of sect. Viorna form a well-supported clade, and several of the traditionally recognized infrasectional taxa were resolved as monophyletic. Although characters employed in classification including habit and inflorescence position …
Nitrogen Application Timing And Cereal Rye (Secale Cereale L.) Cover Crop Influence Greenhouse Gas Emissions, Graig Reicks
Nitrogen Application Timing And Cereal Rye (Secale Cereale L.) Cover Crop Influence Greenhouse Gas Emissions, Graig Reicks
Electronic Theses and Dissertations
Dryland contributions to greenhouse gas (GHG) emissions are increased by N fertilizer applications and high soil water contents. Fertilizer timing and spring growth of cover crops prior to cash crop planting were investigated in separate studies to examine impacts on overall GHG emissions using a near continuous measurement system. There was a significant interaction between N fertilizer rate (0 vs. 224 kg N ha-1 surface-applied as urea) and application date (p= 0.01) for CO2 emissions. This interaction occurred because N fertilizer increased CO2 emissions by 35% for the 21 d interval following early spring application. When application was delayed until …
Species Distribution Modeling Of Aquilegia Brevistyla (Ranunculaceae): A Critically Imperiled Black Hills Disjunct Species, Eric Daniel Puetz
Species Distribution Modeling Of Aquilegia Brevistyla (Ranunculaceae): A Critically Imperiled Black Hills Disjunct Species, Eric Daniel Puetz
Electronic Theses and Dissertations
Unchecked human activity is contributing to rising levels of greenhouse gas emissions, changes in land use, altered disturbance/fire regimes, spread of invasive species, and loss of biological diversity and related breakdown of ecosystem services. Additionally, climatic shifts may lead to phenological mismatches between species and their environments if these changes outpace a species’ ability to adapt or migrate to a more suitable habitat. Isolated mountain populations are particularly threatened by unpredictable climatic conditions, as they may have limited migration corridors and often lower levels of genetic diversity to move or adapt, respectively. As these negative feedbacks compound on the landscape, …

Assessment Of The Ecological Integrity Of Two Wetland Sites Within Eastern Michigan University’S Fish Lake Environmental Education Center (Fleec), Brianna Rice
Master's Theses and Doctoral Dissertations
Wetland ecosystems function as reservoirs of biodiversity for both terrestrial and aquatic organisms, and are among the most vulnerable ecosystems to degradation. The ecological integrity of two wetlands at Eastern Michigan University’s Fish Lake Environmental Education Center, a bog and one vernal pool, was assessed. Plant species richness was used to conduct Floristic Quality Assessments (FQA) using the coefficient of conservatism and wetland indicator status for each species. The Michigan Rapid Assessment Method (MiRAM) was conducted as a more comprehensive assessment of each ecosystem. The bog had an FQA of 31.6 and a MiRAM: 81/100, representing high-quality wetland conditions. The …

U.S. Public Perceptions Of The Sensitivity Of Brain Data, Shenyang Huang, Umika Paul, Shikhar Gupta, Karan Desai, Melinda Guo, Jennifer Jung, Beatrice Capestany, William D. Krenzer, Dylan Stonecipher, Nita A. Farahany
Faculty Scholarship
As we approach an era of potentially widespread consumer neurotechnology, scholars and organizations worldwide have started to raise concerns about the data privacy issues these devices will present. Notably absent in these discussions is empirical evidence about how the public perceives that same information. This article presents the results of a nationwide survey on public perceptions of brain data, to inform discussions of law and policy regarding brain data governance. The survey reveals that the public may perceive certain brain data as less sensitive than other ‘private’ information, like social security numbers, but more sensitive than some ‘public’ information, like …

A “War” Over Lobster And Whales: The Issue-Attention Cycle, Media Discourse, And Political Ecology Of Right Whale Science And Conservation In Six Us Newspapers, Marcus Reamer, Catherine Macdonald, Julia Wester, Russell Fielding, Meryl Shriver-Rice
Honors College Faculty Publications
News organizations and journalists are important and influential actors in environmental politics. Their reporting on social and environmental issues often follows issue-attention cycles (IACs) that emphasize drama and problematization to maintain public interest. This study examined nearly 13 years of news coverage to understand the media discourse about the Critically Endangered North Atlantic right whale (NARW) and its conservation. Content analysis and critical discourse analysis were used to analyze 356 texts published in six large US newspapers between January 1, 2010 and March 15, 2023. NARW conservation and management received increased public attention and an IAC began in 2017 after …
Relationships Between Cliff Swallows (Petrochelidon Pyrrhonota) And Feather Coloration, Morphological Characteristics, And Colony Size, Sonja M. Brandt
Relationships Between Cliff Swallows (Petrochelidon Pyrrhonota) And Feather Coloration, Morphological Characteristics, And Colony Size, Sonja M. Brandt
Master's Theses or Doctor of Nursing Practice
Environmental stressors such as drought and roadways can strongly affect breeding birds. Cliff Swallows (Petrochelidon Pyrrhonota) are aerial insectivores that experience mortality from car collisions, because they often nest and hunt under bridges and road culverts. Individual traits that may convey social information, such as body condition, or feather coloration, might be associated with better coping around cars and other environmental stressors. Few studies have investigated relationships between coloration and other environmental stressors, such as water loss due to drought near the colony and foraging areas. Colony size can be heavily affected by various environmental factors such as water level …

Communicating Climate Change: Adaptive Silviculture In Central Appalachian Kentucky, Logan Baker
Communicating Climate Change: Adaptive Silviculture In Central Appalachian Kentucky, Logan Baker
Theses and Dissertations--Forestry and Natural Resources
Climate change communication is an emerging field that requires a multidisciplinary understanding of both climate and social science. Communicating with underrepresented woodland owners about climate change, specifically climate change adaptation in forestry applications, necessitates appropriately adjusted approaches. In Central Appalachian Kentucky, outreach with underrepresented woodland owners on forest adaptation topics has not been examined in depth. The recent establishment of an Adaptive Silviculture for Climate Change research site in the University of Kentucky’s Robinson Forest has created an opportunity to generate regionally specific climate adaptation information for Appalachian Kentucky forests. It is imperative to investigate how best to approach communicating …
Sensitivity To Artificial Light And Sound In Bats Using Urban Landscapes, Aleana R. Savage
Sensitivity To Artificial Light And Sound In Bats Using Urban Landscapes, Aleana R. Savage
Graduate Theses/Dissertations
Anthropogenic activity has prompted range shifts, extirpations, and behavioral change of native wildlife. Although humans have long altered the landscape, recent (post-1950s) increases in land use intensification has significantly impacted wildlife habitat and biodiversity. As anthropogenic developments and disturbances compromise habitat, some species have begun to exploit urban areas. While there are some commonalities among synurbic species, such as generalist diets and high fecundity, not all urban wildlife share these characteristics. As urban areas expand, it will be essential to distinguish what drives unique species to select for urban habitat. The gray bat, Myotis grisescens, is an endangered species …

Geographical Variation In Songs Of Bachman’S Sparrow (Peucaea Aestivalis), L. Nguyen, K. Doñas, J. Jackson, R. Kannan
Journal of the Arkansas Academy of Science
We present an analysis of geographic variation in primary song components of the Near Threatened North American endemic, Bachman’s Sparrow (Peucaea aestivalis). These songs have 2 distinct portions: an introductory tweet we call the "whistle" and a more complex second portion that we call the "trill". We analyzed 327 songs from 111 recordings downloaded from eBird.org from the entire current range of the species. We grouped the recordings into 3 distinct geographic clusters, East, Central, and West. The data measured from spectrograms suggest a significant statistical difference among groups for 3 measured characteristics: frequency range of trill, number of horizontal …

Nations have committed to reductions in the global rate of species extinctions through the Sustainable Development Goals 14 and 15, for ocean and terrestrial species, respectively. Biodiversity loss is worsening despite rapid growth in the number and extent of protected areas, both at sea and on land. Resolving this requires targeting the locations and actions that will deliver positive conservation outcomes for biodiversity. The Species Threat Abatement and Restoration (STAR) metric, developed by a consortium of experts, quantifies the contributions that abating threats and restoring habitats in specific places offer towards reducing extinction risk based on the IUCN Red List …
Characterizing Prescribed Fire With Terrestrial Lidar In The New Jersey Pine Barrens, Samuel Rhule Stockton
Characterizing Prescribed Fire With Terrestrial Lidar In The New Jersey Pine Barrens, Samuel Rhule Stockton
Graduate Theses, Dissertations, and Problem Reports (ETD)
Prescribed burning has become a commonly used tool in the mitigation of wildfire, though monitoring the way it changes ecosystems has historically been a time-intensive process. Rapid change across ecosystems has necessitated advancements in remote sensing technologies to quantify the changes taking place. Single-scan terrestrial LiDAR scanning is one such method of monitoring these changes through the quantification of ecosystem structural characteristics. Acute disturbance events such as fire can transform the structure of an ecosystem, and by extension, change the way that ecosystem functions. The purpose of this study is to analyze the changes in vegetation density and distribution following …
Late Holocene Fire History Reconstruction Of Beaver Lake In The Northwest Lowlands Of The Olympic Peninsula, Grace Mckenney
Late Holocene Fire History Reconstruction Of Beaver Lake In The Northwest Lowlands Of The Olympic Peninsula, Grace Mckenney
All Master's Theses
Fire is an essential component of the landscapes and forests of the Pacific Northwest, including the temperate rainforests of the Olympic Peninsula. Previous fire history reconstructions from the peninsula show that fire return intervals varied throughout the postglacial period, primarily in response to climatic changes and corresponding shifts in vegetation. However, much less is known about the fire history of the low-elevation forests of the Olympic Peninsula and the role of cultural fire regimes in these environments. The purpose of this study was to reconstruct the paleoenvironmental history of a low-elevation study site, Beaver Lake, located in the northwestern part …

United States Department of Agriculture Wildlife Services: Staff Publications
Understanding landscape scale connectivity is an essential component in the management of invasive species since connectivity facilitates their invasion potential. Invasive wild pigs (Sus scrofa) are among the most prolific invaders on the planet, causing billions of dollars in agricultural and environmental damage annually. Newly introduced to Canada in the 1980s, we examined wild pig invasion potential across the northern prairies from western Canada into the currently wild pig-free northern U.S. states. We used GPS collar data collected in the Canadian prairies to quantify resource selection and incorporated results into an electric circuit theory framework to evaluate potential …

United States Department of Agriculture Wildlife Services: Staff Publications
Understanding the epidemiology and transmission dynamics of transboundary animal diseases (TADs) among wild pigs (Sus scrofa) will aid in preventing the introduction or containment of TADs among wild populations. Given the challenges associated with studying TADs in free-ranging populations, a surrogate pathogen system may predict how pathogens may circulate and be maintained within wild free-ranging swine populations, how they may spill over into domestic populations, and how management actions may impact transmission. We assessed the suitability of Torque teno sus virus 1 (TTSuV1) to serve as a surrogate pathogen for molecular epidemiological studies in wild pigs by investigating …
Quantifying The Ecological Effects Of Salix Fragilis On Riparian Habitat In Kittitas County, Washington, Landon Shaffer
Quantifying The Ecological Effects Of Salix Fragilis On Riparian Habitat In Kittitas County, Washington, Landon Shaffer
All Master's Theses
Invasive species threaten plant community structure and function globally. Riparian areas, the zone near streams where water influences vegetation, are especially sensitive to invasive species colonization, suffering large-scale shifts in community composition. Salix fragilis (crack willow) is a nonnative riparian species abundant in the lower elevation tributaries of central Washington. Some speculate whether this willow should be listed as invasive in Washington, despite a lack of regional supporting evidence. I studied riparian communities dominated by either S. fragilis or native species in the Kittitas Valley and measured biodiversity, quantified differences in solar attenuation, and compared leaf decomposition rates to learn …
