The Influence Of The Environmental Quality Incentives Program On Local Water Quality, Pengfei Liu, Yu Wang, Wei Zhang Jan 2022

The Influence Of The Environmental Quality Incentives Program On Local Water Quality, Pengfei Liu, Yu Wang, Wei Zhang

Environmental and Natural Resource Economics Faculty Publications

The Environmental Quality Incentives Program (EQIP) is the primary conservation program on working agricultural land. The United States Department of Agriculture obligated over $15 billion through EQIP cost-sharing contracts during the fiscal years 2009–2019. The voluntary nature of the program and the lack of performance assessment have led to speculations regarding the effectiveness of the program in delivering environmental benefits, in particular for improving water quality. This study provides quantitative estimates of the influence of EQIP payments on local water quality at a national scale. We link monitoring station level water quality readings with EQIP contract data and exploit the …

Expanding Knowledge On Occupations, One Harmful Occupation At A Time, Taylor Dingus Jan 2022

Expanding Knowledge On Occupations, One Harmful Occupation At A Time, Taylor Dingus

OCCUPATION: A Medium of Inquiry about Health through Occupation

Humans are both natural doers and occupational beings, but in order to consider them as such, one must understand all occupational choices, the meanings and human behavior behind the choices, and the environment in which the choices take place (Helbig & McKay, 2003). Considering self-harm, substance abuse, and addiction as occupations advances this understanding of humans as occupational in nature who are molded by their occupational choices and factors surrounding them (Wasmuth, Brandon-Friedman, & Olesek, 2016). This study aimed to gain an understanding of the occupational nature of humans that engage in occupations defined as harmful by society in order …

Reproducibility And Variability Of Earthquake Subsidence Estimates From Saltmarshes Of A Cascadia Estuary, Jason Scott Padgett, Simon E. Engelhart, Harvey M. Kelsey, Robert C. Witter, Niamh Cahill

Geosciences Faculty Publications

We examine fossil foraminiferal assemblages from 20 sediment cores to assess sudden relative sea-level (RSL) changes across three mud-over-peat contacts at three salt marshes in northern Humboldt Bay, California (~44.8°N, −124.2°W). We use a validated foraminiferal-based Bayesian transfer function to evaluate the variability of subsidence stratigraphy at a range of 30-6000 m across an estuary. We use the consistency in RSL reconstructions to support estimates of coseismic subsidence from megathrust earthquakes. To assess the variability of subsidence estimates, we analyzed: nine examples of the 1700 CE earthquake (average of 0.64 ±0.14 m subsidence; range of 0.24 ± 0.27 to 1.00 …


Passive-Aggressive Intervention: The Impact Of Mandated Paid Parental Leave On Childcare Labor, Justin Fiume Jan 2022

Passive-Aggressive Intervention: The Impact Of Mandated Paid Parental Leave On Childcare Labor, Justin Fiume

Theses - Graduate Programs in Economic Theory and Policy

Gender inequality is one of the few fundamentally persistent inequalities within society, especially in the United States. This thesis will use a Marxist-feminist approach to explore the impact of the United States’ capitalist market economy on gender-specific public and private life structures. Specifically, how inequality is exacerbated as women transition to motherhood. This paper hypothesizes that a mandated paid parental leave would alleviate some of this ‘second burden’ by encompassing fathers in its eligibility. We formulate a difference-in- difference model to estimate the causal effects of two current states who mandate paid parental leave and evaluate the average treatment effect …


Parallel State Currency: A Mechanism To Expand Sovereignty For Countries With Foreign Debt And Trade Deficits, Angelica Huerta Ojeda Jan 2022

Parallel State Currency: A Mechanism To Expand Sovereignty For Countries With Foreign Debt And Trade Deficits, Angelica Huerta Ojeda

Theses - Graduate Programs in Economic Theory and Policy

Some countries, due to historical events, are within a creditor-debtor relationship and are unable to make full use of their currency. Debtor countries tend to not be fully sovereign -are either dependent on food, energy, or technology- which results in them being reliant on capital inflows. Foreign debt and lack of sovereignty feed each other into a debt trap and create an endless chain of dependency. This essay attempts to explore the possibility that governments with foreign debt and lack of sovereignty, like Mexico, should create another unit of account while keeping the current one. The parallel currency would not …


Moderation Of The Association Between Primary Language And Health By Race And Gender: An Intersectional Approach, Neelam H. Ahmed, Mary L. Greaney, Steven Cohen Jan 2022

Moderation Of The Association Between Primary Language And Health By Race And Gender: An Intersectional Approach, Neelam H. Ahmed, Mary L. Greaney, Steven Cohen

Public Health Faculty Publications

In the United States (US), limited English proficiency is associated with a higher risk of obesity and diabetes. “Intersectionality”, or the interconnected nature of social categorizations, such as race/ethnicity and gender, creates interdependent systems of disadvantage, which impact health and create complex health inequities. How these patterns are associated with language-based health inequities is not well understood. The study objective was to assess the potential for race/ethnicity, gender, and socioeconomic status to jointly moderate the association between primary language (English/Spanish) and having obesity and diabetes. Using the 2018 Behavioral Risk Factor Surveillance System (n = 431,045), weighted generalized linear …


The Relative Potency Of Two Drugs Using The Confidence Interval For Ratio Of Means Of Two Normal Populations With Unknown Coefficients Of Variation, Warisa Thangjai, Sa-Aat Niwitpong Jan 2022

The Relative Potency Of Two Drugs Using The Confidence Interval For Ratio Of Means Of Two Normal Populations With Unknown Coefficients Of Variation, Warisa Thangjai, Sa-Aat Niwitpong

Journal of Statistics Applications & Probability

In the paper, the relative potency of two drugs using confidence intervals for the ratio of two means of normal distributions with unknown coefficients of variation is considered. The new confidence intervals were constructed using the large sample approach, the method of variance estimates recovery (MOVER) approach, and then compared with the existing approach: the generalized confidence interval (GCI) approach of Lee and Lin [1]. A simulation study showed that the large sample approach can be used to estimate the confidence interval for the ratio of normal means with unknown coefficients of variation when the value of σY /σX is …

Generalization Of The Ratio Of Minimized Kullback- Leibler Divergence Discrimination Technique To Bivariate Marshall-Olkin Family, Hanan. M. Aly, Ola. A. Abuelamayem

Journal of Statistics Applications & Probability

Different bivariate lifetime distributions are used to analyze lifetime data and study the reliability of the products. Sometimes, we find more than one distribution that fit the data well. In this case, we should select the best one. That is why the discriminant analysis is used. In literature, there is only one method used for bivariate lifetime distributions, which is the likelihood ratio test. In this paper, we try to generalize the ratio of minimized Kullback-Leibler divergence to be used as a discrimination method in the bivariate case and it could be applied on the bivariate Marsall-Olkin family. we will …

Design, Analysis, And Application Of Flipped Product Chaotic System, Md Sakib Hasan, Partha Sarathi Paul, Anurag Dhungel, Maisha Sadia, Md Razuan Hossain Jan 2022

Design, Analysis, And Application Of Flipped Product Chaotic System, Md Sakib Hasan, Partha Sarathi Paul, Anurag Dhungel, Maisha Sadia, Md Razuan Hossain

Faculty and Student Publications

In this paper, a novel method is proposed to build an improved 1-D discrete chaotic map called flipped product chaotic system (FPCS) by multiplying the output of one map with the output of a vertically flipped second map. Two variants, each with nine combinations, are shown with trade-off between computational cost and performance. The chaotic properties are explored using the bifurcation diagram, Lyapunov exponent, Kolmogorov entropy, and correlation coefficient. The proposed schemes offer a wider chaotic range and improved chaotic performance compared to the constituent maps and several prior works of similar nature. Wide chaotic window and improved chaotic complexity …

Cascading Cmos-Based Chaotic Maps For Improved Performance And Its Application In Efficient Rng Design, Partha Sarathi Paul, Maisha Sadia, Md Razuan Hossain, Barry Muldrey, Md Sakib Hasan

Faculty and Student Publications

We present a general framework for improving the chaotic properties of CMOS-based chaotic maps by cascading multiple maps in series. Along with two novel chaotic map topologies, we present the 45 $nm$ designs for four CMOS-based discrete-time chaotic map topologies. With the help of the bifurcation plot and three established entropy measures, namely, Lyapunov exponent, Kolmogorov entropy, and correlation coefficient, we present an extensive chaotic performance analysis on eight unique map circuits (two under each topology) to show that under certain constraints, the cascading scheme can significantly elevate the chaotic performance. The improved chaotic entropy benefits many security applications and …

The General Population's Perception Of Factors Associated With Positive Or Negative Perceptions Of Physical Therapy Care In Those With Low Back Pain, Jada M. Strowbridge

Honors Undergraduate Theses

Low back pain (LBP) has a global impact on health and is a substantial contributor to long term disability. The economic burden of LBP is immense and it is advancing annually. Costs attributing to LBP in the United States is about $84.1 to $624.8 billion. Physical therapy is commonly recommended for those with LBP since it is linked to improved clinical outcomes. However, patient perceptions can influence how this treatment approach is perceived. It is unclear if these perceptions can influence outcomes for patients suffering from LBP. Therefore, the purpose of this study is to identify the factors associated with …

Uv Exposure Causes Energy Trade-Offs Leading To Increased Chytrid Fungus Susceptibility In Green Tree Frog Larvae, Rebecca L. Cramp, Michel E. B. Ohmer, Craig E. Franklin

Faculty and Student Publications

Levels of ultraviolet (UV) radiation have increased in many parts of the world due to the anthropogenic destruction of the ozone layer. UV radiation is a potent immunosuppressant and can increase the susceptibility of animal hosts to pathogens. UV radiation can directly alter immune function via immunosuppression and photoimmunotolerance; however, UV may also influence pathogen defences by affecting the distribution of energy resources among competing physiological processes. Both defence against UV damage and repair of incurred damage, as well as the maintenance of immune defences and responding to an immune challenge, are energetically expensive. These competing demands for finite energy …

Precision Exercise Medicine: Sex Specific Differences In Immune And Cns Responses To Physical Activity, Constanza J. Cortes, Zurine De Miguel Jan 2022

Precision Exercise Medicine: Sex Specific Differences In Immune And Cns Responses To Physical Activity, Constanza J. Cortes, Zurine De Miguel

Psychology Faculty Publications and Presentations

Physical activity is a powerful lifestyle factor capable of improving cognitive function, modifying the risk for dementia associated with neurodegeneration and possibly slowing neurodegenerative disease progression in both men and women. However, men and women show differences in the biological responses to physical activity and in the vulnerabilities to the onset, progression and outcome of neurodegenerative diseases, prompting the question of whether sex-specific regulatory mechanisms might differentially modulate the benefits of exercise on the brain. Mechanistic studies aimed to better understand how physical activity improves brain health and function suggest that the brain responds to physical exercise by overall reducing …

A Ribosomal Protein Homolog Governs Gene Expression And Virulence In A Bacterial Pathogen, Hannah S. Trautmann, Kathryn M. Ramsey Jan 2022

A Ribosomal Protein Homolog Governs Gene Expression And Virulence In A Bacterial Pathogen, Hannah S. Trautmann, Kathryn M. Ramsey

Cell and Molecular Biology Faculty Publications

The molecular machine necessary for protein synthesis, the ribosome, is generally considered constitutively functioning and lacking any inherent regulatory capacity. Yet ribosomes are commonly heterogeneous in composition and the impact of ribosome heterogeneity on translation is not well understood. Here, we determined that changes in ribosome protein composition govern gene expression in the intracellular bacterial pathogen Francisella tularensis. F. tularensis encodes three distinct homologs for bS21, a ribosomal protein involved in translation initiation, and analysis of purified F. tularensis ribosomes revealed they are heterogeneous with respect to bS21. The loss of one homolog, bS21-2, resulted in significant changes …
