Testing The Efficacy Of Surface Swab Sampling To Determine Post-Mortem Submersion Interval (Pmsi), Using The Microbiome Colonization Of Skeletal Remains Submerged In A Lotic Environment, Sarah Rose

Master of Science in Forensic Science Directed Research Projects

Estimating the post-mortem submersion interval (PMSI) can provide a valuable forensic tool for medicolegal death investigations involving victims discovered in aquatic environments. Previous studies conducted by Cartozzo et al. (2021) successfully demonstrated the use of microbial succession to create predictive models for the estimation of PMSI from submerged bone. Though effective, bone sampling requires time consuming processing techniques that result in destruction of decedent tissue. This study investigates the use of bone surface swabbing as an effective alternative method to bone sampling, with the goal of predicting PMSI using a simpler, non-invasive sampling technique. Porcine (Sus scrofa) skeletal remains (rib …

In order to estimate the original gas-in-place, predict the production rates, and optimize the hydraulic …

Centennial High: A School For Hope And Growth, Augustina Teuber

Architecture Theses

In this paper, high school design is evaluated in order to better support the mental health of its occupants. The alarming rise in anxiety, depression, and violence among youth over the past few decades demonstrates the importance of changing society’s current trajectory. Thus this paper aims to clarify the extent design impacts users and how educational buildings can benefit adolescent mental health. Literature analysis from a diverse range of fields guides these conclusions. Additionally, case study analysis and logical argumentation are employed to identify practical solutions. Ultimately, an example design for a mental health conscious public school is purposed.

Effects Of States’ Laws On Youth Physical Activity Participation And Obesity Prevalence, Chae Young Chang

Midwest Social Sciences Journal

The alarming prevalence of obesity and lack of physical activity among adolescents led to immediate policy action to address these concerns. Accordingly, many states introduced and enacted their own legislation to encourage physical activity in schools. Few studies have explored the effectiveness of the new legislation, however, especially at the state level. To answer the fundamental question of whether policy is effective and to describe the varying effects of state obesity policies, this study analyzed the Youth Risk Behavior Surveillance System from 2007 to 2017. Using the difference-in-differences method, this study found that legislative efforts to encourage physical activity had …

Profitable Retail Customer Identification Based On A Combined Prediction Strategy Of Customer Lifetime Value, Yinglu Sun, Dong Cheng, Subir Bandyopadhyay, Wei Xue

Midwest Social Sciences Journal

As a fundamental concept of customer relationship management, customer lifetime value (CLV) serves as a crucial metric to identify profitable retail customers. Various methods are available to predict CLV in different contexts. With the development of consumer big data, modern statistics and machine learning algorithms have been gradually adopted in CLV modeling. We introduce two machine learning algorithms—the gradient boosting decision tree (GBDT) and the random forest (RF)—in retail customer CLV modeling and compare their predictive performance with two classical models—the Pareto/NBD (HB) and the Pareto/GGG. To ensure CLV prediction and customer identification robustness, we combined the predictions of the …

Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler

Graduate Theses, Dissertations, and Problem Reports (ETD)

Soils in the Monongahela National Forest (MNF) are acidic due to sandstone parent material, acid deposition, uptake of base cations by vegetation, and release of organic acids by organic matter (OM) decomposition. Increases in soil acidity have caused declines in forest health and changed species composition and nutrient status. Liming can neutralize soil acidity, but no large-scale liming projects have been done on acid forest soils in the USA. In anticipation of acquiring funding for a proposed liming project in the MNF, in 2007 and 2009 10 sites were selected to sample and analyze soils before lime was applied. In …

In all three essays, I use housing data to value various amenities and disamenities. Using several variations on the hedonic method, I am able to uncover the values based on the capitalization effect. I consider the effect of natural resource development by examining shale gas development, as well as the effect of urban development projects, including public transportation and sports facilities.

In the first essay of my dissertation, …

Optical Hygiene And Modernity: A Site Analysis Of Hyperion Water Reclamation Plant Using Lefebvre’S Triad, William R. Stone

Pomona Senior Theses

Hyperion Water Reclamation Plant sits at the edge of Los Angeles County as an almost unknowable infrastructure. Unlike the city block, the grocery store, or one’s own home, this integral part of the urban landscape asks not to be experienced by its users, only the employees who work there every day. This place, which I’d hesitate to call a place, amalgamates preconceptions about infrastructure, sewage, purity, danger, modern architecture, and the role of the state.

In this thesis I conduct a site analysis of Hyperion Water Reclamation Plant in three parts, or moments based loosely on Henri Lefebvre’s conceptual triad: …

The Design, Development And Validation Of A Persuasive Content Generator, Sam Khataei, Michael J. Hine, Ali Arya

Journal of International Technology and Information Management

This paper addresses the automatic generation of persuasive content to influence users’ attitude and behaviour. Our research extends current approaches by leveraging individuals’ social media profiles and activity to personalize the persuasive content. Unlike most other implemented persuasive technology, our system is generic and can be adapted to any domain where collections of electronic text are available. Using the Yale Attitude Change approach, we describe: the multi-layered Pyramid of Individualization model; the design, development, and validation of integrated software that can generate individualized persuasive content based on a user’s social media profile and activity. Results indicate the proposed system can …

Our Past Creates Our Present: A Brief Overview Of Racism And Colonialism In Western Paleontology, Pedro M. Monarrez, Joshua B. Zimmt, Annaka M. Clement, William Gearty, John J. Jacisin Iii, Kelsey M. Jenkins, Kristopher Mm. Kusnerik, Carmi Milagros Thompson, Ashley W. Poust, Selina V. Robson, Judith A. Sclafani, Kelsey T. Stilson, Shamindri D. Tennakoon

School of Biological Sciences: Faculty Publications

As practitioners of a historical science, paleontologists and geoscientists are well versed in the idea that the ability to understand and to anticipate the future relies upon our collective knowledge of the past. Despite this understanding, the fundamental role that the history of paleontology and the geosciences plays in shaping the structure and culture of our disciplines is seldom recognized and therefore not acted upon sufficiently. Here, we present a brief review of the history of paleontology and geology in Western countries, with a particular focus on North America since the 1800s. Western paleontology and geology are intertwined with systematic …

The Role Of Peer Irrigators On The Choice And Intensity Of Use Of Irrigation Techniques, Noah Hayward, Kent Kovacs

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The use and the proportion of farmland that uses prominent irrigation practices in Arkansas were evaluated. A bivariate sample selection model evaluated the determinants of the share of irrigated land in a farm that uses each practice. In addition, the relationship between the irrigation practices a peer uses and the use and intensity of five common irrigation practices was evaluated. If a peer of an Arkansas farmer used center pivot irrigation, this increased the probability that the farmer used center pivot irrigation by 66 percentage points. A peer that used pivot irrigation decreased the proportion of irrigated land that used …

Exploring How Maternal Phosphorus Status Affects Calf Growth And Performance, Elizabeth Lafferty, Beth Kegley, Brittni Littlejohn, Jeremy Powell

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Phosphorus is an important component of bodily functions and is critical for adequate growth and development. This experiment evaluated the effect of maternal phosphorus intake on the growth and health of the calves. Treatments were 1) a free-choice mineral containing no supplemental P or 2) a free-choice mineral with 4% supplemental phosphorus. Primiparous, or pregnant for the first time, crossbred Angus beef cows (n = 36) were stratified by body weight and pregnancy status (bred by artificial insemination or natural service) then assigned to pasture groups (4 groups, 2/treatment, 9 heifers/group). These bred heifers had been receiving these same dietary …

Water Clarity At The River-Estuary Transition Zone: A Comparative Study Of The James, Mattaponi, And Pamunkey Sub-Estuaries, Rachel Henderson

Theses and Dissertations

Water clarity is a key parameter for monitoring water quality and often used to assess habitat suitability for submerged aquatic vegetation (SAV). Light attenuation, a measure of water clarity, is impacted by colored dissolved organic matter (CDOM), and by suspended particulates which include living and non-living components. We anticipated that the relative importance of these factors in regulating light attenuation would vary among the upper portions of three sub-estuaries differing in morphometry, hydrology, and degree of human influence. The James is characterized by eutrophic conditions and high algal abundance, whereas the Mattaponi and Pamunkey exhibit lower phytoplankton production. The Mattaponi …

Searching For Gold: Using A Novel Land Cover Classification To Identify Multiscale Drivers Of Site Occupancy By A Flagship Species For Early-Successional Habitat Conservation, Baron Lin

Theses and Dissertations

Understanding habitat selection at multiple scales is an important step in guiding conservation programs and reversing species declines. This, however, is difficult for species that occupy early-successional habitats (ESH) due to a lack of accurate representation of shrub cover in publicly available land cover data. The Golden-winged Warbler (Vermivora chrysoptera; GWWA) is a threatened species of conservation concern and a flagship for ESH conservation. We used a novel, LIDAR-derived land cover classification that accurately identifies shrubs at a fine resolution (1m) to investigate how habitat composition and configuration influence GWWA site occupancy. We aggregated this same land cover …

A Spatiotemporal Assessment Of Fish Assemblage Response To Land-Use Change And The Evaluation Of Edna Metabarcoding For Describing Diverse Fish Communities, Timothy M. Owen

Theses and Dissertations

Fish assemblages are often assessed as a biological proxy for environmental health. While humans value healthy environments for the ecosystem services and recreational opportunities they provide, it is increasingly evident that such resources can be paradoxically degraded by anthropogenic activities. In this investigation, we studied the relationship between different intensities of anthropogenic land-use change and habitat-driven fish assemblage response across multiple spatiotemporal scales. Secondarily, we explored the efficacy of eDNA metabarcoding against conventional electrofishing techniques for the purpose of describing complete fish communities. This study was conducted in the Tuckahoe Creek basin near Richmond, Virginia. This James River tributary serves …

Using Dialogue To Contextualize Culture, Ecosystem Services, And Cultural Ecosystem Services, Karen Allen, Celia Castellano, Sophia Pessagno

Open Access Fund Publications

We propose an alternative methodology for engaging with multifaceted cultural ecosystem services (CES) in the Global South. We explore the use of dialogue as a tool for understanding CES in situ, while developing shared action steps toward CES conservation among stakeholders. We held six dialogue workshops in the rural Central Pacific region of Costa Rica that were designed to foster understanding of shared community values for ecosystem services and associated conservation challenges. In two of the workshops, we employed model-based reasoning through which we used maps as boundary negotiating objects to nurture dialogue on CES values, observations, and concerns. In …

'Awakening The Sleeping Giant': Re-Indigenization Principles For Transforming Biodiversity Conservation In Canada And Beyond, M’S-It No’Kmaq, Albert Marshall, Karen F. Beazley, Jessica Hum, Shalan Joudry, Anastasia Papadopoulos, Sherry Pictou, Janet Rabesca, Lisa Young, Melanie Zurba

Articles, Book Chapters, & Popular Press

Precipitous declines in biodiversity threaten planetary boundaries, requiring transformative changes to conservation. Colonial systems have decimated species and ecosystems and dispossessed Indigenous Peoples of their rights, territories, and livelihoods. Despite these challenges, Indigenous governed lands retain a large proportion of biodiversity-rich landscapes. Indigenous Peoples have stewarded the land in ways that support people and nature in respectful relationship. Biodiversity conservation and resurgence of Indigenous autonomies are mutually compatible aims. To work towards these aims requires significant transformation in conservation and re-Indigenization. Key to both are systems that value people and nature in all their diversity and relationships. This paper introduces …

Using Noninvasive Techniques To Monitor Game Species Targeted By Poaching In Misiones, Argentina, Pryscilha M. Delgado, Carina F. Argüelles, Karen E. Dematteo

Neotropical Biodiversity

Misiones, Argentina contains the largest remnant of Upper Paraná Atlantic forest; however, half of it is unprotected. The long-term survival of its biodiversity is threatened by poaching and habitat loss, which eliminate animal populations and decrease genetic variability in species. Noninvasive techniques were used to evaluate the presence of four mammals [white-lipped peccary (Tayassu pecari), collared peccary (Pecari tajacu), tapir (Tapirus terrestris), and paca (Cuniculus paca)] often targeted by poachers. With detection dogs, 179 scats were collected across intact and modified habitats in the northern-central zones of Misiones. Of the samples collected, 76.5% (n = 137) could be genetically confirmed …

Dna Barcoding Approach To Characterize Microalgae Isolated From Freshwater Systems In Ecuador, Isabel Ballesteros, Paulina Terán, Cristina Guamán-Burneo, Nory González, Alejandra Cruz, Pablo Castillejo

Neotropical Biodiversity

The use of suitable DNA barcodes and the generation of databases with reference sequences have been considered a promissory approach for the identification of Chlorophyta and Cyanophyta microalgae. In this study, we carried out a molecular characterization and identification of strains isolated from freshwater systems in Ecuador using a dual barcode method. The target sequences for Chlorophyta were 18S rDNA and rbcL genes, and 16S rDNA and 16S–23S rDNA intergenic spacer (ITS) for Cyanophyta. We reported these DNA barcodes for 20 different Molecular Operational Taxonomic Units (MOTUs) for Chlorophyta and 10 for Cyanophyta. Our results show that the 18S V4 …

Perkembangan Teknologi Informasi, Tfp, Dan Emisi Gas Co2 Di Indonesia, Ganiko Moddilani, Irwandi Irwandi

Jurnal Ekonomi dan Pembangunan Indonesia

This paper examines the development of information technology, total factor productivity (TFP), and urbanization of CO2 gas emissions in Indonesia from 1975–2014. To discuss empirically, this study uses the Autoregressive Distributed Lag (ARDL) model. There are several results in this study. Firstly, the TFP coefficient value in the short term is lower than the long term, so that the Enviromental Kuznets Curve (EKC) hypothesis is not proven. This is one of the causes of rising CO2 gas emissions. Secondly, information technology has a significant impact on the increase of CO2 gas emissions. Thirdly, Indonesia’s urbanization has reduced CO2 gas emissions.

The Transcorporeal South: Bodies And Ecologies In Twentieth-Century Southern Literature, Tiffany Morgan Messick

Graduate Research Theses & Dissertations

This dissertation proposes that transcorporeality offers an alternative to Cartesian dualistic modes of embodiment in Walker Percy’s, The Moviegoer, Zora Neale Hurston’s, Their Eyes Were Watching God, Richard Wright’s, Native Son, and Carson McCullers’s The Heart is a Lonely Hunter. Opposing the division between mind and body as theorized by René Descartes, transcorporeality advances the body’s porosity, maintaining that the individual is enmeshed within the material world and that this entanglement consubstantiates consciousness. Examining the works of Descartes, focusing especially on the ways that Cartesian ideas have been applied in Southern culture, I contend that a Cartesian definition of subjectivity, …
