Local Injections Of Β-Ngf Accelerates Endochondral Fracture Repair By Promoting Cartilage To Bone Conversion., Kevin O. Rivera, Fabrizio Russo, Ryan M. Boileau, Ryan E. Tomlinson, Theodore Miclau, Ralph S. Marcucio, Tejal A. Desai, Chelsea S. Bahney

Department of Orthopaedic Surgery Faculty Papers

There are currently no pharmacological approaches in fracture healing designed to therapeutically stimulate endochondral ossification. In this study, we test nerve growth factor (NGF) as an understudied therapeutic for fracture repair. We first characterized endogenous expression of Ngf and its receptor tropomyosin receptor kinase A (TrkA) during tibial fracture repair, finding that they peak during the cartilaginous phase. We then tested two injection regimens and found that local β-NGF injections during the endochondral/cartilaginous phase promoted osteogenic marker expression. Gene expression data from β-NGF stimulated cartilage callus explants show a promotion in markers associated with endochondral ossification such as Ihh, Alpl, …

Motivations, Environmental Attitudes, And Personal Efficacy Of Volunteers At Communitree Tree-Planting Events In Northwest Indiana, U.S., Kaitlyn Pike, Rebecca Brokaw, Jess Vogt

Cities and the Environment (CATE)

In this paper, we examine the mechanisms of volunteering at tree-planting events conducted as part of a new, multi-organizational tree-planting effort in northwest Indiana called CommuniTree. A broad literature exists on general volunteerism as well as environmental volunteering, urban forestry volunteering, and even tree-planting volunteering. Yet, the motivations, environmental attitudes, and personal efficacy of urban forestry volunteers in particular are not fully understood, nor are the outcomes and implications of volunteer participation in neighborhood greening programs. A 22-question (34 individual items), self-report survey was administered in-person at CommuniTree tree-planting events in 2017 through 2019, obtaining 114 responses. CommuniTree volunteers who …

Tracing Carbon Sources Of Southern Beaufort Sea And Chukchi Sea Polar Bears Using Stable Isotope Analyses, Malia E.K. Smith

Marine Biology

The Southern Beaufort Sea (SBS) polar bear (Ursus maritimus) subpopulation has declined in response to sea ice loss, while the Chukchi Sea (CS) subpopulation appears stable. The substantial population decline in the SBS subpopulation in recent years is concurrent with increases in the proportion of polar bears coming on shore, and the duration they spend there. Both of these changes have been associated with the loss of access to their primary sea ice habitat, which is mainly used as a platform to hunt seals. The first objective of this study was to determine if the SBS and CS polar bear …

Genomic Signatures Of Optimal Growth Temperature In The Family Colwelliaceae, Anais Gentilhomme

Oceanography

The temperature range supporting growth defines a complex physiological phenotype that depends on interactions between an organism's genome and its environment. Its implications are widespread since small changes in optimal growth temperature (OGT) can alter an organism's ability to inhabit an ecological niche. Thus, organisms with extreme thermal growth traits (e.g., psychrophilic, with OGT < 15℃, or thermophilic, with OGT 60 -80℃) may be useful for identifying promising targets when searching for life on other planets, as well as predicting population dynamics in a warming Arctic. We performed comparative genomic analyses of bacteria newly isolated from Arctic sea ice that were affiliated with Colwelliaceae, a family of Gammaproteobacteria that contains many psychrophilic strains, to identify genomic factors that might be used to predict OGT. A phylogenomic analysis of 67 public and 39 newly-sequenced strains, was used to construct an updated phylogenetic tree of Colwelliaceae, of which at least two genera were well represented. To augment the previously reported OGTs of 26 strains, we measured growth rates at −1, 4, 11, and 17 ℃ to determine the OGTs of these 39 new strains of Colwelliaceae. We found that growth rates among all isolates were comparable at −1℃, but varied widely above 10 ℃, indicating higher variability in the ability to tolerate warmer temperatures. To analyze the phenotypic differences on a genomic level, we examined indices of amino acid substitutions that have previously been linked with cold adaptation via an increase in protein flexibility. We found that these indices were significantly correlated with OGT at the whole genome level, although the sign of some correlations were opposite of the predicted positive correlation between temperature and the indices. Using these data, we fit a multiple linear regression model for OGT within the Colwelliaceae family that incorporates the three most informative amino acid indices: GRAVY, Aliphatic Index, and Acidic Residue Proportion. Additionally, a putative cold-adaptive gene cassette was identified that was likely introduced by horizontal gene transfer between two closely related clades with different OGTs. These contributions offer key insights into OGT variability and its underlying genomic foundation in the family Colwelliaceae.

Quantifying Deepfake Detection Accuracy For A Variety Of Natural Settings, Pratikkumar Prajapati

Master's Projects

Deep fakes are videos generated from a starting video of a person where that person's face has been swapped for someone else's. In this report, we describe our work to develop general, deep learning-based models to classify Deep Fake content. Our first experiments involved simple Convolution Neural Network (CNN)-based models where we varied how individual frames from the source video were passed to the CNN. These simple models tended to give low accuracy scores for discriminating fake versus non-fake videos of less than 60%. We then developed three more sophisticated models: one based on choosing test frames, one based on …

Threat, Opportunity, Cooperation, And Competition: Defining China's Integration Into The Arctic, Susan Elizabeth Bowman

Arctic and Northern Studies

Despite widespread attention to China's interest in the Arctic, little research examines how the country approaches the region. This thesis uses an inductive and qualitative approach to examine China's relationships with the eight Arctic states and major international institutions in the Arctic. This thesis asks: How is China integrating into the Arctic? How do Arctic states view China's integration? Through content analysis, narratives tell the story of China's relationship with the Arctic 8 and Arctic institutions. China's integration is explored on a fundamental level through the comparison of bilateral and multilateral relations, followed by more strategic undertones including threat, opportunity, …

Brian Reynolds, Public Visibility, And Gay Stardom, Finley Freibert

Faculty and Staff Scholarship

Once gracing the covers of numerous gay newspapers and magazines, Brian Reynolds was a key figure of Los Angeles’ emergent gay adult film industry of the late 1960s. He had all but disappeared from gay adult film historiography until he re-emerged as a cover model for a scholarly journal in 2012, to illustrate pioneering scholarship that initiated contemporary Pat Rocco studies. This article puts the story of Brian Reynolds in dialogue with critical star studies in order to offer a recovery history of Reynolds. Reynolds’ rise to celebrity and sudden relegation to obscurity underscores the historical instability of gay pornographic …

Como Olvidarte, Emilce Quiroz

Capstones

Being in both the Spanish and Documentary concentrations, I had to produce a short documentary in the Spanish language and produce a piece of written work to go along with it. For my capstone, I chose to focus on a homicide case that happened in Mexico City in 2015. It caught international attention and although many people have their own thoughts and beliefs as to what happened that day, I wanted to provide a platform for the families to express their own feelings of loss, injustice, and their own versions of the truth. This case was highly distorted by the …

Technoference: Parent Mobile Device Use And Implications For Children And Parent-Child Relationships., Brandon T. Mcdaniel Phd

Health Services and Informatics Research

The increase in the prevalence of smartphones and mobile devices has spurred changes in the caregiving environment of infants and young children, as phones and mobile devices are used at times during caregiving and in caregiving spaces. This use could create disruptions and cause distractions during parenting (termed technoference). This article summarizes the potential impacts on parent responsiveness and the experiences of infants and young children. Yet, it also warns that it is important to consider the reason for and type of parent use. Finally, the article ends with practical tips for working with parents concerning mobile device use.

Effects Of Sea Ice Seasonal Evolution And Oil Properties On Crude Oil Upward Migration Through Sea Ice, Marc Oggier

Geosciences

Sea ice plays an essential role in polar ecosystems as a habitat for organisms at the base of the food web. Receding Arctic perennial sea ice, potential oil and gas reserves, and increasing industrial activities in the Arctic are likely to increase oil extraction and transport in the maritime Arctic. Despite a decrease in summer sea ice extent, Arctic waters remain covered with sea ice for much of the year, increasing the risk of an oil spill in and under Arctic sea ice. This dissertation addresses the need for a quantitative understanding of the timing of and constraints on oil …

Palestinian Women’S Agency, Yasmin Khodary

Political Science

In Civil Resistance and Conflict Transformation, Veronique Dudouet divides responses to oppression into two main analytical categories. The first category refers to conventional actions, including party politics, advocacy or diplomacy, dialogue and negotiations, and litigation. The second category is non-intuitional/contentious actions including: first, nonviolent/unarmed/peaceful resistance through protest and persuasion, non-cooperation, disruptive intervention and creative resistance and second, violent/armed resistance through warfare, terrorist attacks, guerrilla insurgency, protest violence and sabotage. These two sub-categories of resistance operate outside the bounds of conventional political channels and are usually employed by an oppressed minority or disempowered majority by an exclusionary national or foreign actor. …

Suicide By Cop: A Secondary Analysis Using Open-Source News Data, Mckayla Nolan

Theses

Suicide by cop (SBC) has recently become a known phenomenon in the United States, Canada, Australia and parts on the United Kingdom as another way to complete suicide (Patton & Fremouw,2015). SBC refers to when an individual creates a scenario in which law enforcement agencies are called and have to use deadly force in order to protect themselves and the people around the individual who is attempting to take their life (Mohandie, Meloy, & Collins, 2009). The term suicide by cop was originally coined by a police officer and psychologist Karl Harris in 1983 and is the term that is …

Monetary Impact Of National Exchange Carrier Association Tariffs On Internet Access Cost In Rural Areas, Tim Obermier, Angela K. Hollman

Mountain Plains Journal of Business and Technology

This study examines the monetary impact of tariffs on consumer internet access via a digital subscriber line (DSL). Historically, the Communications Act of 1934 mandated that telephony services be provided to everyone, without exclusion. With the rapid emergence of the internet, the Connect America Fund was recently implemented to ensure equal access to both voice and broadband services. Since many telephony companies have emerged as internet service providers, DSL internet service is often bundled together with a landline telephone, especially in rural areas. This study examines the total cost of such bundled DSL internet service across the classes of cities …

Google And Shifting Conceptions Of What It Means To Improve A Product, Ramsi Woodcock

Law Faculty Popular Media

Judges sometimes claim that they do not pick winners when they decide antitrust cases. Nothing could be further from the truth.

Competitive conduct by its nature harms competitors, and so if antitrust were merely to prohibit harm to competitors, antitrust would then destroy what it is meant to promote.

What antitrust prohibits, therefore, is not harm to competitors but rather harm to competitors that fails to improve products. Only in this way is antitrust able to distinguish between the good firm that harms competitors by making superior products that consumers love and that competitors cannot match and the bad firm …
