Unsupervised Categorical Clustering On Labor Markets, Matthew James Steffen Apr 2023

Unsupervised Categorical Clustering On Labor Markets, Matthew James Steffen

Theses and Dissertations

During this "white collar recession,'' there is a flooded labor market of workers. For employers seeking to hire, there is a need to identify potential qualified candidates for each job. The current state of the art is LinkedIn Recruiting or elastic search on Resumes. The current state of the art lacks efficiency and scalability along with an intuitive ranking of candidates. We believe this can be fixed with multi-layer categorical clustering via modularity maximization. To test this, we gathered a dataset that is extensive and representative of the job market. Our data comes from PeopleDataLabs and LinkedIn and is sampled …

Finished, Shayla Frandsen

Theses and Dissertations

Sixteen-year-old Tiny Sinclair begins her first year at Charity Ambrose Finishing School in 1953 already feeling like an outcast: her mother, a glamorous movie star, is dead, and her father is imprisoned under suspicion of being a Communist. All her classmates seem to have it so easy: beautiful Betty is an elegant and popular socialite, while Diane, the richest girl in school, is dangerous and mysterious (and, for some reason, hell-bent on ruining Tiny's life). When a classmate is found dead and Tiny becomes the number one suspect, the situation seems to go from bad to worse. Determined to clear …

Halophilic Genes That Impact Plant Growth In Saline Soils, Mckay A. Meinzer Apr 2023

Halophilic Genes That Impact Plant Growth In Saline Soils, Mckay A. Meinzer

Theses and Dissertations

Many plants are highly sensitive to salt in the soil, and their growth and yield can be greatly hindered by as little as less than 1% salt concentration in the soil. Additionally, soil salinity is a growing issue globally and affects significant areas in Utah. Halophytes are plants that are adapted to grow in saline soils and have been widely studied for their physiological and molecular characteristics, but little is known about their associated microbiomes. Bacteria were isolated from the rhizosphere and as root endophytes of Salicornia rubra, Sarcocornia utahensis, and Allenrolfea occidentalis, three native Utah halophytes. Several strains of …

O Silêncio Da Mulher Carioca Oitocentista E Sua Representação No Romance Naturalista Lar De Pardal Mallet, Jessyca Kimberly De Oliveira Zanetti Apr 2023

O Silêncio Da Mulher Carioca Oitocentista E Sua Representação No Romance Naturalista Lar De Pardal Mallet, Jessyca Kimberly De Oliveira Zanetti

Theses and Dissertations

The 19th century represents the arrival of the Portuguese royal family in Brazil and, with it, significant changes in society and the local population. A formerly reclusive member of society begins to take shape not only in public life but also within the literature: the Brazilian woman. Despite her changing social role, prevailing hygienist and medical theories of the time pointed to the lack of vocation of the nineteenth-century woman for rational matters; which in naturalism implies that these pseudo-scientific theories would be the base to dissect and explain the social pathologies of Rio de Janeiro, Brazil, and society at …

Characterizing The Informativity Of Level Ii Book Data For High Frequency Trading, Logan B. Nielsen Apr 2023

Characterizing The Informativity Of Level Ii Book Data For High Frequency Trading, Logan B. Nielsen

Theses and Dissertations

High Frequency Trading (HFT) algorithms are automated feedback systems interacting with markets to maximize returns on investments. These systems have the potential to read different resolutions of market information at any given time, where Level I information is the minimal information about an equity--essentially its price--and Level II information is the full order book at that time for that equity. This paper presents a study of using Recurrent Neural Network (RNN) models to predict the spread of the DOW Industrial 30 index traded on NASDAQ, using Level I and Level II data as inputs. The results show that Level II …

Utilizing Isothermal Titration Calorimetry To Measure Β-Galactosidase Activity In Dairy Products, Tyler Ronald Jarrard Apr 2023

Utilizing Isothermal Titration Calorimetry To Measure Β-Galactosidase Activity In Dairy Products, Tyler Ronald Jarrard

Theses and Dissertations

The dairy industry uses enzymes to make cheese, alter product flavor, and eliminate lactose. The activities of these enzymes have been measured in clear buffered solutions, but because of the limitations of spectrophotometric methods, enzyme activities have not been measured in opaque or colored dairy products where they are used. Isothermal titration calorimetry (ITC) can be used to determine reaction kinetics in opaque and colored solutions by measuring the heat rate from enzyme-catalyzed reactions as a function of time. This study used ITC to measure β-galactosidase activity in opaque solutions of milk, sweet whey, sweet whey permeate, acid whey, and …

Network Representation Theory In Materials Science And Global Value Chain Analysis, Mats C. Haneberg Apr 2023

Network Representation Theory In Materials Science And Global Value Chain Analysis, Mats C. Haneberg

Theses and Dissertations

This thesis is divided into two distinct chapters. In the first chapter, we apply network representation learning to the field of materials science in order to predict aluminum grain boundaries' properties and locate the most influential atoms and subgraphs within each grain boundary. We create fixed-length representations of the aluminum grain boundaries that successfully capture grain boundary structure and allow us to accurately predict grain boundary energy. We do this through two distinct methods. The first method we use is a graph convolutional neural network, a semi-supervised deep learning algorithm, and the second method is graph2vec, an unsupervised representation learning …

The Topology And Dynamics Of Surface Diffeomorphisms And Solenoid Embeddings, Xueming Hui Apr 2023

The Topology And Dynamics Of Surface Diffeomorphisms And Solenoid Embeddings, Xueming Hui

Theses and Dissertations

We study two topics on surface diffeomorphisms, their mapping classes and dynamics. For the mapping classes of a punctured disc, we study the $\ZxZ$ subgroups of the fundamental groups of the corresponding mapping tori. An application is the proof of the fact that a satellite knot with braid pattern is prime. For the mapping classes of the disc minus a Cantor set, we study a special type of reducible mapping class. This has direct application on the embeddings of solenoids in $\mathbb{S}^3$. We also give some examples of other types of mapping classes of the disc minus a Cantor set. …

Development And Validation Of A Spanish Nutrition Screening Tool For Hispanic American 3 To 5-Year-Olds, Denisse Arias Olivas Apr 2023

Development And Validation Of A Spanish Nutrition Screening Tool For Hispanic American 3 To 5-Year-Olds, Denisse Arias Olivas

Theses and Dissertations

Latinos comprise 18.9% of the population in the United States and are the largest and fastest growing minority group. Obesity prevalence was 26.2% among Hispanic children compared to 16.6% among non-Hispanic White children. The obesity epidemic among Latino children has been growing rapidly over the past three decades. Multiple barriers, such as lack of culturally appropriate screening tools, language, and lack of access to nutritional assessment and expert consultation, prevents screening of Latino children and further nutritional guidance. For this reason, prevention efforts such as the use of nutritional screening tools is required for early intervention, more so with populations …

Language Modeling Using Image Representations Of Natural Language, Seong Eun Cho Apr 2023

Language Modeling Using Image Representations Of Natural Language, Seong Eun Cho

Theses and Dissertations

This thesis presents training of an end-to-end autoencoder model using the transformer, with an encoder that can encode sentences into fixed-length latent vectors and a decoder that can reconstruct the sentences using image representations. Encoding and decoding sentences to and from these image representations are central to the model design. This method allows new sentences to be generated by traversing the Euclidean space, which makes vector arithmetic possible using sentences. Machines excel in dealing with concrete numbers and calculations, but do not possess an innate infrastructure designed to help them understand abstract concepts like natural language. In order for a …

Real-Time Imaging And Measurement Of Compartmentalized Redox Shifts Using Novel Redox-Sensitive Biosensors: Implications In Developmental Toxicology, Brandon Mitchell Davies Apr 2023

Real-Time Imaging And Measurement Of Compartmentalized Redox Shifts Using Novel Redox-Sensitive Biosensors: Implications In Developmental Toxicology, Brandon Mitchell Davies

Theses and Dissertations

Glutathione (GSH) is a small antioxidant in the body and exists in large quantities compared to other antioxidants. The GSH redox state (Eh) helps developmental processes, however, when the GSH Eh is disrupted, cells may undergo significantly poor developmental pathways, possibly leading to long-lasting damages. Similarly, NADPH and Thioredoxin redox states can have a major impact on cellular function, viability, and response to both endogenous and exogenous toxicants. Subcellular, compartmentalized redox environments during normal or perturbed situations, specifically in the cytosol, mitochondria, and nucleus, are not well understood. Here, using the P19 neurogenesis model of cellular differentiation, the kinetics of …

A Comparison Of The Vascular Response To Acute Sauna Heating In Young And Middle-Aged Adults, Olivia Kathryn Leach Apr 2023

A Comparison Of The Vascular Response To Acute Sauna Heating In Young And Middle-Aged Adults, Olivia Kathryn Leach

Theses and Dissertations

BACKGROUND: Age-related declines in endothelial function have been well documented with larger declines observed in middle-aged. Passive heat exposure has been shown to be a promising method to improve vascular endothelial health, with sauna specifically being linked to reduced risk of cardiovascular disease. Increases in blood flow and shear rates associated with heat exposure are often considered to have a major influence on the observed improved endothelial function following heat exposure. The magnitude of these changes in response to sauna have not yet been defined. Therefore, the purpose of this study is to quantify and compare the vascular response to …

Large-Scale Testing Of Lightweight Cellular Concrete Backfill For Sliver-Fill Mse Wall Configurations, Meghann Dee Morgan Apr 2023

Large-Scale Testing Of Lightweight Cellular Concrete Backfill For Sliver-Fill Mse Wall Configurations, Meghann Dee Morgan

Theses and Dissertations

Lightweight cellular concrete (LCC) is an aerated or foamed concrete where 25-80% of the concrete matrix consists of air voids. The high volume of air voids reduces the strength but significantly decreases the weight of the material, which has made it an attractive alternative to soil for retaining structure backfills. Though the use of LCC has increased, little research has been performed on the large-scale behavior of retaining structures containing LCC as backfill. This research test attempts to fill knowledge gaps found with regard to the use of LCC in a mechanically stabilized earth (MSE) wall with a trapezoidal or …

The War On Gender Equality: A Comparative Study Between Feminism And Anti-Feminism In South Korea And The United States, Ashley Dipenti Apr 2023

The War On Gender Equality: A Comparative Study Between Feminism And Anti-Feminism In South Korea And The United States, Ashley Dipenti

Undergraduate Honors Theses

Since the time of Confucianism and the development of patriarchal systems in South Korea, there have been distinct differences between male and female experiences and roles in various aspects of Korean life. The gendered history of South Korea has led to a gap between the two genders that persists today in important areas of Korean society, such as education and social life. As both genders struggle for equality and representation, both sides argue that they are being discriminated against. This struggle has led to two major groups being formed in South Korea (hereafter Korea): feminists and anti-feminists. The following review …

Pausing In American English: Documenting Native English Speakers' Pausing Patterns, Ammon Hunt Apr 2023

Pausing In American English: Documenting Native English Speakers' Pausing Patterns, Ammon Hunt

Theses and Dissertations

The purpose of this study was to examine more deeply the relationship between pause location and duration and its connection to clause and phrase boundaries for native English speakers (NESs). Previous research has shown pauses produced by NESs to be located at clause boundaries (Brown & Miron, 1971; Hawkins, 1971; Tavakoli, 2011), but little empirical work has been done to probe this issue further. For this research, 80 speech samples, 40 male and 40 female, were randomly selected from the International Dialects of English Archive (IDEA) representing different regions in the United States. Oral data from the read-aloud portion of …

The Impact Of Speech Pause On The Perceived Effectiveness And Likability Of A Speaker's Communication, Rebecca Lyman Apr 2023

The Impact Of Speech Pause On The Perceived Effectiveness And Likability Of A Speaker's Communication, Rebecca Lyman

Theses and Dissertations

The purpose of this study was to examine how length and location of speech pausing affects a listeners' perception of likability and communication effectiveness. Furthermore, the end goal of this study is to understand how to better assess atypical speech pause for persons with aphasia (PWA). Speech samples were collected from two neurotypical speakers over the age of 75. The speech samples were the recorded responses of picture description tasks found in the Western Aphasia Battery (WAB) and the Boston Diagnostic Aphasia Examination (BDAE). These speech samples were then modified to include artificial pauses located both within sentence and between …

Party Contacting, Group Identity, And Covid-19: An Analysis Of Asian American Voter Turnout In 2020, Suzy Yi Apr 2023

Party Contacting, Group Identity, And Covid-19: An Analysis Of Asian American Voter Turnout In 2020, Suzy Yi

Sigma: Journal of Political and International Studies

Many scholars have examined what affects voter turnout rates among racial minorities compared to that of White voters. Racial minorities consistently turn out to vote in elections at lower rates than White voters. One method of combating low voter turnout is through party contacting, in which political parties mobilize people who are most likely to vote through activities such as door-to-door canvassing or individualized contact through mail, phone calls, and texts (Huckfeldt and Sprague 1992; Wielhouwer and Lockerbie 1994). However, because political parties direct their efforts towards those who are most likely to vote, they are more likely to favor …

The Growing Greens: How Young Postmaterialists Delivered Electoral Success For The German Green Party In 2021, Isaac Lamoreaux Apr 2023

The Growing Greens: How Young Postmaterialists Delivered Electoral Success For The German Green Party In 2021, Isaac Lamoreaux

Sigma: Journal of Political and International Studies

The German Green Party seemed to be forever a secondary party in German politics. That is, until the German General Election in 2021 when they gained more seats in the Bundestag than any other party. Many wondered how such a small party could perform such a feat. Scholars, particularly Ronald Inglehart, have theorized on and studied the concept of postmaterialism. In a basic sense, postmaterialism is a set of values that turns away from safety and security concerns (materialism), and more toward what Inglehart called intellectual and aesthetic concerns (Inglehart 1971, 991–993). These concerns range from topics like freedom of …

The Junk Food Problem: Why The Law Allows Advertising To Kids And How To Implement Change, Makenna Hardy, Madison Maloney Apr 2023

The Junk Food Problem: Why The Law Allows Advertising To Kids And How To Implement Change, Makenna Hardy, Madison Maloney

Brigham Young University Prelaw Review

Rapid technological advancements have increased the methods in which advertisers can reach the public, specifically children. As obesity rates increase among America’s youth, more stringent advertising laws barring junk food exposure have been advocated for. Since the Supreme Court has determined commercial free speech as deserving full First Amendment coverage, the rights of advertisers frequently inhibit productive methods of protecting children from junk food advertisements. This article examines the current standards safeguarding both children and advertisers and the feasibility of restricting advertising to kids within the limitations of commercial speech protections.

An Ironic Alliance: The Domestic Foundations Of Qatar’S Support For Democratic Revolution Abroad, Jonah Phillips Apr 2023

An Ironic Alliance: The Domestic Foundations Of Qatar’S Support For Democratic Revolution Abroad, Jonah Phillips

Sigma: Journal of Political and International Studies

When the wave of revolutions commonly referred to as the Arab Spring engulfed the Arab world in the early 2010s, regional powers were suddenly presented with a potentially complete restructuring of the Arab world’s political and social structure. In the years leading up to the uprisings, rising food prices, soaring unemployment, and widespread political corruption had converged to make the Middle East and North Africa a fertile ground for revolution. The mounting pressure came to a head in December of 2010 when demonstrations broke out across Tunisia following the self-immolation of a street vendor protesting police corruption. The following months …

Utah Antidiscrimination Efforts: Shortcomings, Challenges, And The Way Forward, Greta L. Asay Apr 2023

Utah Antidiscrimination Efforts: Shortcomings, Challenges, And The Way Forward, Greta L. Asay

Brigham Young University Prelaw Review

Despite being a pro-business state, Utah is not considered employee-friendly; employment discrimination is prevalent, in spite of the state and federal laws in place to protect against it. The state agency that is in place to safeguard employees against unlawful discrimination is the Utah Antidiscrimination and Labor Division (UALD), established by the Utah Antidiscrimination Act (UADA). While the UALD has the potential to be a powerful legal guardrail for employees, it currently is not fulfilling this potential. This paper explores the shortcomings of the UALD and argues that changes should be made to strengthen the authority of the UADA.

The Fourth Amendment In A Digital Age: Defining Boundaries In Law Enforcement Surveillance Of The Home, Josh Hoffman, Jared Xia Apr 2023

The Fourth Amendment In A Digital Age: Defining Boundaries In Law Enforcement Surveillance Of The Home, Josh Hoffman, Jared Xia

Brigham Young University Prelaw Review

As our country enters a new digital age, emerging technologies have increased the ability of law enforcement to monitor American citizens more closely. The tracking of suspects through thermal imaging, video monitoring, and cell phone GPSs are just a few examples of the unlocked potential now available to investigating authorities. When directed at the home, these technologies allow for unprecedented encroachment of our most intimate sphere of daily life. With this accelerating prevalence of technology in surveillance practices comes the need to reassess what boundaries the Fourth Amendment defines for our privacy. This paper explores the application of the Reasonable …

Checking The President’S Sanctioning Power In The New Age Of Economic Warfare, Jaden Mcquivey Apr 2023

Checking The President’S Sanctioning Power In The New Age Of Economic Warfare, Jaden Mcquivey

Brigham Young University Prelaw Review

The United States President has nearly unlimited sanctioning power. This paper agrees with presidential authority over sanctions, which has been firmly established by the Trading With the Enemy Act of 1917, International Emergency Economic Powers Act in 1977, United States v. Curtiss-Wright Export Corp., and INS v. Chadha. However, this paper does not agree with unchecked sanctioning power. By simply declaring a national emergency, the President can legally justify most economic sanctions on foreign countries. Over the last few decades, the United States has entered a new state of “sanctioning madness” and is known for its particularly destructive unilateral sanctions. …

Explaining Guatemalan Vigilantism, Bryant Mcconkie Apr 2023

Explaining Guatemalan Vigilantism, Bryant Mcconkie

Sigma: Journal of Political and International Studies

Ripped from his home in Concepción, Guatemala, the evening of October 13, 2015, Mayor Bacilio Juracán was brutally beaten, doused with gasoline, and burned to death by attackers convinced he had orchestrated the murder of a political rival they supported. In just this one isolated incident, the town hall, various cars, and at least six additional buildings were burned along with the mayor (“Linchan y Queman” 2015). A growing number of similar lynchings—vigilante attacks in which victims of the mob are severely injured or killed—across Guatemala have thrust Guatemalan vigilantism into the public consciousness, perplexing governments and political theorists alike …

The Impact Of Gender On The Acceptance Of Surveillance Technology, Jody Messick Apr 2023

The Impact Of Gender On The Acceptance Of Surveillance Technology, Jody Messick

Sigma: Journal of Political and International Studies

A classic dilemma facing governments and citizens alike is the trade-off between privacy and security. This concept is found in the Constitution’s Fourth Amendment, which implies that citizens have a right to be protected against “unreasonable searches and seizures by the government” (FindLaw 2019). The technological revolution, and its implications for privacy, has complicated the nature of this right. Different types of data require different approaches to the privacy versus security tradeoff. A 2003 panel by Wright et. al asks how “sensor data,” data that is collected through technology that tracks a user’s online or real-world movements, should be approached, …

Internet Censorship In The Time Of A Global Pandemic: A Proposal For Revisions To Section 230 Of The Communications Decency Act, Braxton Johnson, Alex Dewsnup Apr 2023

Internet Censorship In The Time Of A Global Pandemic: A Proposal For Revisions To Section 230 Of The Communications Decency Act, Braxton Johnson, Alex Dewsnup

Brigham Young University Prelaw Review

During the era of the novel coronavirus SARS-CoV-2, social media sites have justified removing inflammatory opinions pertaining to COVID-19 in attempts to protect and promote public health and safety by automatically categorizing such opinions as misinformation. While the intention of such censorship is noble, it raises the question of whether social media sites and internet service providers in general have too much power when it comes to controlling information. In an age where social media has become intrinsic to the dissemination and formation of opinion, the free exchange of ideas on the Internet is of prime importance, and any threat …

The Gig-Economy War: The Drive Towards Regulating Rideshare Employment Misclassification, Inae Cavalcante Apr 2023

The Gig-Economy War: The Drive Towards Regulating Rideshare Employment Misclassification, Inae Cavalcante

Brigham Young University Prelaw Review

With the emergence of the gig-economy, the doctrine distinguishing independent contractors from employees has never been more relevant in the state of California. Currently, the state faces a legal battle regarding employment misclassification of rideshare apps’ drivers, specifically Uber Technologies. While many believe that drivers should be entitled to the label of employee and receive benefits and protections under the California Labor Code, the law is not tailored to this new market and renders itself ambiguous. Although many solutions were presented in the past, such as the Borello Test, the ABC Test, Assembly Bill 5, and Proposition 22, no employment …

Local Partisan Agreement And Trust, Mike Pulsipher, Kelsey Eyre Apr 2023

Local Partisan Agreement And Trust, Mike Pulsipher, Kelsey Eyre

Sigma: Journal of Political and International Studies

Americans are more distrusting than ever. On every metric, there has been a noticeable and substantial decline in trust of government, media, and business. This important trend has received a lot of academic and press attention and has been identified in nearly every state and every demographic. Curiously, despite decades of falling crime, fraud, and corruption, Americans are also less trusting in each other. While changes in trust for government, media, and business have looked quite different for Democrats and Republicans, partisans have shown similar declining trends in general trust.
