A Novel Supercritical Co2-Based Decellularization Method For Maintaining Scaffold Hydration And Mechanical Properties, Michael A. Matthews, Tarek Shazly, Rachel M. Handleton, Dominic M. Casali

Faculty Publications

Decellularized tissues are commonly utilized as tissue engineering scaffolds. Decellularization by extended exposure to aqueous detergents can damage the microstructure or deposit cytotoxic residue. Supercritical carbon dioxide (scCO2) has been proposed for decellularization, but reportedly causes dehydration and scaffold embrittlement.

Presented herein is a novel decellularization method that preserves matrix hydration state and mechanical properties. Over 97% of the water in porcine aorta is maintained by presaturating scCO2 with water; however, complete decellularization was not attained by any process utilizing only scCO2. Instead, a novel hybrid method is presented that combines a brief (48 h) exposure of tissue to aqueous …

The Legal Foundations Of White Supremacy, Erika K. Wilson

Faculty Publications

This paper focuses on a very important part of white supremacy — the legal foundations of white supremacy. The central thesis of this paper is that American law has historically played a vital role in constructing white supremacy. While America has eliminated overt race-conscious laws that favor whites, the law continues to play a critical role in maintaining white supremacy today. Unless and until we commit to understanding the history of the law in constructing white supremacy and the ways in which modern iterations of law continue to perpetuate white supremacy, white supremacy will remain an enduring feature of American …

Alcoholic And Nonalcoholic Parents’ Orientations Toward Conformity And Conversation As Predictors Of Attachment And Psychological Well-Being For Adult Children Of Alcoholics, Marie Haverfield, Jennifer Theiss

Faculty Publications

Alcoholism is a family illness that has implications for the physical, emotional, and psychological well-being of the spouse and children of individuals with alcoholism (Johnson & Stone, 2009). One in four families in the United States is affected by alcoholism (Grant, 2000), with approximately 26.8 million children growing up with a parent with alcoholism (Alcohol and Drug Programs [ADP], 2007). Children of parents with alcoholism tend to experience more frequent depression and struggle to develop healthy intimate relationships when compared to children of parents without alcoholism (Drejer, Theikjaard, Teasedale, Schulsinger, & Goodwin, 1985). Adult children of alcoholics (ACoA) who had …

The History And Political Economy Of The Hatch-Waxman Amendments, Erika Lietzan

Faculty Publications

Reform of the Hatch–Waxman generic drug framework is in the air. Scholars, consumer advocacy groups, regulated industry, and policymakers are engaged in heated debate about perceived shortcomings in the scheme, flaws, and unexpected loopholes. Changes in how the U.S. Food and Drug Administration (FDA) implements the law, as well as changes to the law itself, are under serious consideration. These policymaking discussions take place against a backdrop of shared assumptions about the origins and nature of the original Hatch–Waxman legislation — assumptions that this Article claims are wrong. Convention wisdom holds that the Hatch–Waxman legislation was a delicate compromise privately …

Academic Information On Twitter: A User Survey, Ehsan Mohammadi, Mike Thelwall, Mary Kwasny, Kristi L. Holmes

Faculty Publications

Although counts of tweets citing academic papers are used as an informal indicator of interest, little is known about who tweets academic papers and who uses Twitter to find scholarly information. Without knowing this, it is difficult to draw useful conclusions from a publication being frequently tweeted. This study surveyed 1,912 users that have tweeted journal articles to ask about their scholarly-related Twitter uses. Almost half of the respondents (45%) did not work in academia, despite the sample probably being biased towards academics. Twitter was used most by people with a social science or humanities background. People tend to leverage …

Defining The Opioid Epidemic: Congress, Pressure Groups, And Problem Definition, Taleed El-Sabawi

Faculty Publications

The passage of the Comprehensive Addiction and Recovery Act of 2016 evidences a shift in federal legislative support from criminal justice oriented legislative alternatives to more health oriented legislative alternatives to addressing the ongoing Opioid Epidemic. Such a shift was preceded by a redefinition of problem drug use in the policy discourse from an issue of deviancy to a health issue. However, the redefinition of problem drug use as a health issue, has been dominated by policy narratives and causal stories that do not define problem drug use in a manner that aligns with a multi-modal public health oriented legislative …

Walking In Minimalist Shoes Is Effective For Strengthening Foot Muscles, Sarah T. Ridge, Mark T. Olsen, Dustin A. Bruening, Kevin Jurgensmeier, David Griffin, Irene S. Davis, A. Wayne Johnson

Faculty Publications

Introduction: Weakness of foot muscles may contribute to a variety of loading-related injuries. Supportive footwear may contribute to intrinsic foot muscle weakness by reducing the muscles’ role in locomotion (e.g., absorbing forces and controlling motion). Increased stimulus to the foot muscles can be provided through a variety of mechanisms, including minimalist footwear and directed exercise.

Purpose: To determine the effect of walking in minimalist footwear or performing foot strengthening exercises on foot muscle size and strength.

Methods: Fifty-seven runners were randomly assigned to one of three groups—minimalist shoe walking (MSW), foot strengthening (FS) exercise, or control (C). All groups maintained …

This study investigated the design cognition and performance results of secondary and post-secondary engineering students while engaged in an engineering design task. Relationships between prototype performance and design cognition were highlighted to investigate potential links between cognitive processes and success on engineering design problems. Concurrent think-aloud protocols were collected from eight secondary and 12 post-secondary engineering students working individually to design, make, and evaluate a solution prototype to an engineering design task. The collected protocols were segmented and coded using a pre-established coding scheme. The results were then analyzed to compare the two participant groups and determine the relationships between …

Comparing L1 And L2 Texts And Writers In First-Year Composition, Grant Eckstein, Dana Ferris

Faculty Publications

Scholars have at various points discussed the needs of second language (L2) writers enrolled in “mainstream” composition courses where they are mixed with native (L1) English speakers. Other researchers have investigated the experiences of L2 writers in mainstream classes and the perceptions of their instructors about their abilities and needs. Little research, however, has directly compared L1 and L2 students (mostly Generation 1.5) taking composition classes together. For this article, the researchers collected writing samples from 56 L1 and 74 L2 students enrolled in a university (mainstream) first-year composition course. Using a mixed-methods design, they analyzed the texts for language …

Examining The Impact And Influence Of The Leisure Science Literature, Mat D. Duerden, Michael B. Edwards, Michael C. Goates, Justin Dyer

Faculty Publications

This study explored the impact and influence of the leisure sciences literature through an analysis of highly cited articles. Discriminant function analysis identified whether articles had more exclusive impact inside or outside the field. Research themes and methodologies were examined based on these classifications. Results indicate articles with the greatest impact within the leisure literature tended to be quantitative studies drawing upon survey data and non-experimental designs focused on general leisure and outdoor/forest recreation. Articles with the greatest impact outside the leisure literature were more recent and focused on place attachment, psychological motivation, or community parks and recreation and used …

Navigating The Teen Years: The Adolescent Brain And Christ’S Atonement, Mark H. Butler, Genevieve L. Smith

Faculty Publications

Like other spiritually sincere youth, Caleb struggles with pornography use. At first, he was repulsed by it, but he found himself drawn back to it. The arousal was preoccupying and pleasurable. Pornography use became a habit. He still wanted to go on a mission, marry in the temple, be a worthy father. Repeatedly, he resolved to stop using pornography. He felt anger and shame every time he fell short. Caleb became discouraged and felt like he could never change. He felt that he didn’t deserve God’s or anyone else’s love and forgiveness because of all his broken promises.

Blended Learning: The New Normal And Emerging Technologies, Charles Dziuban, Charles R. Graham, Patsy D. Moskal, Anders Norberg, Nicole Sicilia

Faculty Publications

This study addressed several outcomes, implications, and possible future directions for blended learning (BL) in higher education in a world where information communication technologies (ICTs) increasingly communicate with each other. In considering effectiveness, the authors contend that BL coalesces around access, success, and students’ perception of their learning environments. Success and withdrawal rates for face-to-face and online courses are compared to those for BL as they interact with minority status. Investigation of student perception about course excellence revealed the existence of robust if-then decision rules for determining how students evaluate their educational experiences. Those rules were independent of course modality, …

Bioremediation of soil and groundwater sites contaminated by petroleum hydrocarbons is known as a technically viable, cost-effective, and environmentally sustainable technology. The purpose of this study is to investigate laboratory-scale bioremediation of petroleum-hydrocarbon contaminated soil through development of eight bioreactors, two bioreactors for each bioremediation mode. The modes were: (1)natural attenuation (NA); (2) biostimulation (BS) with oxygen and nutrients; (3) bioaugmentation (BA)with hydrocarbon degrading isolates; (4) a combination of biostimulation and bioaugmentation (BS-BA). Total petroleum hydrocarbons (TPH) mass balance over the bioreactors showed about 2% of initial20,000 mg kg-soil−1TPH was removed by advection due to synthetic groundwater which was flow-ing …

Changes In Estuarine Sediment Phosphorus Fractions During A Large-Scale Mississippi River Diversion, Eric D. Roy, Nhan T. Nguyen, John R. White

Faculty Publications

Ongoing deterioration and loss of wetlands in the Mississippi River delta threatens the survival of Louisiana's coastal ecosystems and human settlements. In response, the State of Louisiana has proposed a $50 billion, 50-year restoration program. A central piece of this program is the reintroduction of Mississippi River water into the deltaic plain using managed diversions that mimic natural flood pulses. These diversions would transport critically needed sediment, but also deliver large nutrient loads. Coastal eutrophication is therefore a concern, particularly blooms of toxin-producing cyanobacteria. The Bonnet Carré Spillway (BCS) is an existing large flood diversion that protects New Orleans and …

Polyamines In The Life Of Arabidopsis: Profiling The Expression Of S -Adenosylmethionine Decarboxylase ( Samdc ) Gene Family During Its Life Cycle, Rajtilak Majumdar, Lin Shao, Swathi A. Turlapati, Subhash C. Minocha

Faculty Publications

Arabidopsis has 5 paralogs of the S-adenosylmethionine decarboxylase (SAMDC) gene. Neither their specific role in development nor the role of positive/purifying selection in genetic divergence of this gene family is known. While some data are available on organ-specific expression of AtSAMDC1, AtSAMDC2, AtSAMDC3 and AtSAMDC4, not much is known about their promoters including AtSAMDC5, which is believed to be non-functional. (1) Phylogenetic analysis of the five AtSAMDC genes shows similar divergence pattern for promoters and coding sequences (CDSs), whereas, genetic divergence of 5’UTRs and 3’UTRs was independent of the promoters and CDSs; (2) while AtSAMDC1 and AtSAMDC4 promoters exhibit high …
