This study purposed to investigate the level of pesticide residues and the potential health risk associated with vegetables, surface water, and sediment obtained from the river basin area. The concentrations of 87 pesticides from four main groups namely; organophosphate, organochlorine, pyrethroid, and persistent organic pollutants (POPs) were verified by triple quadrupole GC-MS/MS. The concentration of Parathion methyl, Methidathion, Bromophos methyl, Chlorfenvinphos, Triazophos, Azinphos ethyl, and D-trans-Phenothrin …

Teaching Economic Risk Management Through A Video Game Concept, Samantha Montella

Senior Honors Projects

Many video games imply economic behavior: making decisions within a game highlights the fundamentals of human action. The basic idea is that virtual worlds, like the real world, present us with a series of choices. Games impose digital scarcity, obliging players to weigh the benefits of different courses of action, make tradeoffs, and incur costs.

Good examples are found in the role-playing game (RPG) genre, where players face tough choices between different specializations and skill trees. Obliging players to make difficult decisions highlights the opportunity costs of choice, not the money cost. Games also encourage players to think entrepreneurially: to …

How Water Level And Irrigation Practices Affect Waterbird Community, Nesting, And Foraging Habitat Use On The Duck Valley Indian Reservation, Jamie L. Burke

Boise State University Theses and Dissertations

Loss of habitat continues to threaten all bird populations. Despite efforts for conservation of wetlands, waterbirds continue to face habitat threats especially in western North America where water resources are limited across the landscape. The White-faced Ibis (Plegadis chihi) is a colonial nesting waterbird of conservation concern that builds nests in emergent vegetation of freshwater wetlands throughout the western United States. An ibis breeding colony site located at the Blue Creek Wetland complex on Duck Valley Indian Reservation may face habitat threats in the future due to plans intended to increase irrigation water use efficiency. Plans include manipulation …

Experiences, Concerns, & Needs Of Foster Parents To Promote Child Resiliency, Emma Friemel

Human Development and Family Sciences Undergraduate Honors Theses

Children in foster care are highly likely to have experienced some form of abuse or neglect, along with a host of other negative or harmful experiences. These experiences can leave them vulnerable when faced with difficult situations in the future. This research examines the various factors that may affect a foster child’s ability to be resilient in future adverse situations. There are several studies that examine the resiliency of children in foster care, but few examine resiliency from the perspective of the child’s foster parents. Three hundred and sixteen prospective, current, and future foster parents in the state of Oklahoma …

The Impact Of Extreme Heat On Environmental Justice Communities In California: Assessing Equity In Climate Action Plans, Karishma S. Becha

Master's Projects and Capstones

Climate change projections suggest extreme heat events will be more frequent over the next few decades. Extreme heat has both negative environmental and social impacts as it affects energy security, public health by increasing the risk of heat-related illnesses and stresses food and crop supply through prolonged droughts. The impacts of extreme heat will also disproportionately affect communities of low economic status. Because of this, there is a need for better climate action plans that can adapt to and mitigate the impacts brought upon by extreme heat that does not disproportionately impact vulnerable communities. This research analyzed local government Climate …

Memorialization On College Campuses Today, Virginia Thornton

Geography and the Environment Capstone Projects

This study uses the theoretical basis of placemaking and memorialization to examine the placement of memorial landscapes on college campuses. The research is based in case study analysis of other college campuses. It looks specifically at where and what is memorialized and what elements of placemaking are incorporated. The main postulate of my research is that the location of the memorialization of the suspected slave burial ground and history of slave labor on Richmond’s campus is appropriately placed in the Eco-corridor. The research suggests this postulate is not true, as the majority of other memorials have been placed in more …

Stormwater Management For A Healthier Campus Watershed: The Value-Add Of Green Stormwater And Watershed Management To The University Of Richmond’S Campus Landscape, Nia Cambridge

We will focus on the emergence of green technology and how China is exporting its technology globally.

Evolutionary Bioethics Advanced By Ernest Everett Just: Implications For Biology, Ethics, And Theology, Theodore Walker

Perkins Faculty Research and Special Events

Ernest Everett Just (1883-1941) is an acknowledged “pioneer” in biology, being honored with a Black Heritage postage stamp in 1996. Here we discover that Just also made pioneering contributions to general evolutionary bioethics (distinct from special medical bioethics) by advancing a cell-biology-rooted theory of the origin and continuing evolution of ethical behavior influenced by the “law of environmental dependence.”

See especially “The Origin of Man’s Ethical Behavior (1941, unpublished book manuscript) by Ernest Everett Just and Hedwig Schnetzler Just, discovered in 2018 among the collected papers of E.E. Just at the Moorland-Spingarn Research Center at Howard University.

Accordingly, evolution is …

Aquaculture has been presented as a means of income for coastal communities, particularly in the context of climate change and resource exploitation. The NGO Marine Cultures in Jambiani, Zanzibar has established a sponge cultivation program for women in response to declining feasibility of seaweed farming from warming ocean temperatures. In addition, the organization strives to restore a severely damaged reef while providing employment for coral farmers and tour boat operators. This study analyzed the influence of aquaculture on community stakeholders, primarily with respect to sponge cultivation and secondarily in regard to coral farms. Using Marine Cultures as a case study, …

Road Development In Asia: Assessing The Range-Wide Risks To Tigers, Neil Carter, Alexander Killion, Tara Easter, Jodi Brandt, Adam Ford

Human-Environment Systems Research Center Faculty Publications and Presentations

Roads are proliferating worldwide at an unprecedented rate, with potentially severe impacts on wildlife. We calculated the extent and potential impacts of road networks across the 1,160,000-km², 13-country range of the globally endangered tiger (Panthera tigris)—a conservation umbrella species. We found that roads were pervasive, totaling 134,000 km across tiger conservation landscapes (TCLs), even in tiger priority sites and protected areas. Approximately 43% of the area where tiger breeding occurs and 57% of the area in TCLs fell within the road-effect zone. Consequently, current road networks may be decreasing tiger and prey abundances by more than …

Biophilia In Everyday Life, Olivia Duke

Virginias Collegiate Honors Council Conference

Mindfulness is an important practice in daily life that many have forgotten in our fast-paced consumerist society. When we are advised to be mindful, we tend in think that we don’t have the time or money for it – but really it involves simple and inexpensive choices. I found my own inspiration through Biophilia, a movement encouraging the reintegration of nature into daily life. Simply taking a moment to be grounded in your surroundings can drastically boost your mood. Biophilia encourages healthy living of both body and mind. Taking care of ourselves as well as our natural environment is vital …

Decision-Support System For Lid Footprint Planning And Urban Runoff Mitigation In The Lower Rio Grande Valley Of South Texas, Javier Guerrero, Taufiqul Alam, Ahmed Mahmoud, Kim D. Jones, Andrew Ernest

Civil Engineering Faculty Publications

To address regional flooding in the United States, federal and state agencies are adopting strict drainage policies in any large-scale commercial development within the watershed boundary. The conventional approach of implementing a wet detention pond (WP) reduces the land cover and causes operation and maintenance challenges eventually. The present study developed a decision-support system (DSS) in the Lower Rio Grande Valley region of South Texas for optimal selection of Best Management Practices (BMPs) by substituting a portion of the WP footprint with three regionally promising low-impact development practices, namely, porous concrete pavement (PCP), bioretention (BR), and bioswale (BS). Source Load …

Transformative Change In Rural Ethiopia: The Impact Of Small- And Medium-Scale Irrigation, Logan Cochrane, Anne Cafer

Journal of Rural Social Sciences

Rural livelihoods in Ethiopia are vulnerable due to their reliance upon variable rainfall and the lack of access to irrigation. Irrigation coverage in the country is low, as the existing systems tend to cover state-run and commercial operations. There is significant potential for irrigation to play a transformative role in rural lives and livelihoods. Much of the evidence available in Ethiopia focuses upon technical studies of irrigation systems or impacts on households after gaining access to irrigation. This article highlights the causes and pathways of change. We focus on more financially-viable and environmentally-sound small- and medium-scale systems, versus the large-scale …

Uav-Based Remote Sensing Of Immediate Changes In Geomorphology Following A Glacial Lake Outburst Flood At The Zackenberg River, Northeast Greenland, Aleksandra M. Tomcyzk, Marek W. Ewertowski

Environment and Society Student Research

Two detailed geomorphological maps (1:2000) depicting landscape changes as a result of a glacial lake outburst flood were produced for the 2.1-km-long section of the Zackenberg river, NE Greenland. The maps document the riverscape before the flood (5 August 2017) and immediately after the flood (8 August 2017), illustrating changes to the riverbanks and morphology of the channel. A series of additional maps (1:800) represent case studies of different types of riverbank responses, emphasising the importance of the lateral thermo-erosion and bank collapsing as significant immediate effects of the flood. The average channel width increased from 40.75 m pre-flood to …
