Mechanisms Controlling Copper Transport In Natural Soils, Julie A. Luisi

Civil and Environmental Engineering Master's Project Reports

Biosolids are used as amendments to agricultural soils and can be a source of trace metals. It is unknown if these land-applied trace metals travel through the soil column to the water table. This study aims to determine the transport behavior of copper in natural soils, including 'aged' soils, commercial agricultural soils that have had multiple years of biosolids applications. Using acid digests and Darcy column apparatus it was determined that factors such as pH, soil composition, especially organic matter content, and the presence of other trace metals influence copper’s complex transport behavior in these soils. Natural soil appears to …

Evaluation Of The Influence Of Wording Changes And Course Type On Motivation Instrument Functioning In Chemistry, Regis Komperda, Kathryn N. Hosbein, Jack Barbera

Chemistry Faculty Publications and Presentations

Increased understanding of the importance of the affective domain in chemistry education research has led to the development and adaptation of instruments to measure chemistry-specific affective traits, including motivation. Many of these instruments are adapted from other fields by using the word ‘chemistry’ in place of other disciplines or more general ‘science’ wording. Psychometric evidence is then provided for the functioning of the new adapted instrument. When an instrument is adapted from general language to specific (e.g. replacing ‘science’ with ‘chemistry’), an opportunity exists to compare the functioning of the original instrument in the same context as the adapted instrument. …

Device Therapies Among Patients Receiving Primary Prevention Implantable Cardioverter-Defibrillators In The Cardiovascular Research Network, Robert T. Greenlee, Alan S. Go, Pamela N. Peterson, Andrea E. Cassidy-Bushrow, Charles Gaber, Romel Garcia-Montilla, Alan H. Kadish

Office of the President Publications and Research

BACKGROUND: Primary prevention implantable cardioverter-defibrillators (ICDs) reduce mortality in selected patients with left ventricular systolic dysfunction by delivering therapies (antitachycardia pacing or shocks) to terminate potentially lethal arrhythmias; inappropriate therapies also occur. We assessed device therapies among adults receiving primary prevention ICDs in 7 healthcare systems.

METHODS AND RESULTS: We linked medical record data, adjudicated device therapies, and the National Cardiovascular Data Registry ICD Registry. Survival analysis evaluated therapy probability and predictors after ICD implant from 2006 to 2009, with attention to Centers for Medicare and Medicaid Services Coverage With Evidence Development subgroups: left ventricular ejection fraction, 31% to 35%; …

Outer Limits Of Biotechnologies: A Jewish Perspective, John D. Loike, Alan H. Kadish

Office of the President Publications and Research

A great deal of biomedical research focuses on new biotechnologies such as gene editing, stem cell biology and reproductive medicine, which have created a scientific revolution. While the potential medical benefits of this research may be far-reaching, ethical issues related to non-medical applications of these technologies are demanding. We analyze, from a Jewish legal perspective, some of the ethical conundrums that society faces in pushing the outer limits in researching these new biotechnologies.

Secondary Teachers' Perceptions And Self-Efficacy Regarding Technology Integration: A Phenomenological Study, Christopher Brantley

Doctoral Dissertations and Projects

The purpose of this phenomenological study was to examine how teachers from various levels of technology self-efficacy perceive and implement technology within their specific classroom. Using a qualitative approach, I explored four public schools from a medium to large-sized school district in the Southeastern United States. The Technology Integration Confidence Scale (TICS) was used to purposively select 10 secondary teachers from the west side of Beach County (a pseudonym). The secondary teachers were placed into three groups based upon their individual self-efficacy level towards technology integration: (a) low, (b) average, and (c) high. Data was collected through the following methods: …

Tarry There! Spiritual Endowment For Today's Generation Per Luke 24:49, Cleveland Taylor

Doctoral Dissertations and Projects

This project will revisit the biblical significance of the treatment of tarry in Luke 24:49 (KJV) and the key principle of waiting on the timing of God’s provision of “power” promised to accomplish the job description He has given Christians. A period of radical fasting and prayer retreat will be an initial tarry presented to encounter the Holy Spirit experience. The word for power that Luke uses in Luke 24:49 and Acts 1:8 references “that ability to do work.” Acts 1:4 placed emphasis on the disciples not leaving Jerusalem without the promise. The potential value of this topic is in …

Efficacy Of Human Placental-Derived Stem Cells In Collagen Vii Knockout (Recessive Dystrophic Epidermolysis Bullosa) Animal Model, Yanling Liao, Larisa Ivanova, Rajarajeswari Sivalenka, Trevor Plumer, Hongwen Zhu, Xiaokui Zhang, Mitchell S. Cairo

NYMC Faculty Publications

Recessive dystrophic epidermolysis bullosa (RDEB) is a devastating inherited skin blistering disease caused by mutations in the COL7A1 gene that encodes type VII collagen (C7), a major structural component of anchoring fibrils at the dermal-epidermal junction (DEJ). We recently demonstrated that human cord blood-derived unrestricted somatic stem cells promote wound healing and ameliorate the blistering phenotype in a RDEB (col7a1(-/-) ) mouse model. Here, we demonstrate significant therapeutic effect of a further novel stem cell product in RDEB, that is, human placental-derived stem cells (HPDSCs), currently being used as human leukocyte antigen-independent donor cells with allogeneic umbilical cord blood stem …

Restore, Revert, Repeat: Examining The Decompensation Cycle And The Due Process Limitations On The Treatment Of Incompetent Defendants, Margaret W. Smith

Vanderbilt Law Review

Though correctional facilities are one of the largest providers of mental health care in the country, the treatment provided often fails to address the needs of many mentally ill inmates. Indeed, after receiving treatment at a state mental health facility, many pretrial detainees who have been recently restored to competency revert to an incompetent state-or decompensate-upon their return to jail, at which point they must return to the state treatment facility to be restored to competency once again. This Note is the first to explore this "decompensation cycle," highlighting the significance of the problem and demonstrating how mental health treatment …

Funding Restrictions And Separation Of Powers, Zachary S. Price

Vanderbilt Law Review

Congress's "power of the purse"-its authority to deny access to public funds-is one of its most essential constitutional authorities. A central mechanism through which English parliaments clawed liberty from reluctant monarchs, it remains a crucial check on executive overreaching. It may provide power to stop a president in his tracks. And yet, two centuries after the founding, the scope of this congressional power and its relationship with constitutional executive authorities remains both contested and inadequately theorized.

Invisible Bars: Adapting The Crime Of False Imprisonment To Better Address Coercive Control And Domestic Violence In Tennessee, Alexandra M. Ortiz

Vanderbilt Law Review

On average, three or more women are murdered by their intimate partners in the United States every day. Despite the now well-known correlation between coercive control-the strategic use of oppressive behavior to control primarily female partners-and intimate partner homicide, most states continue to focus their criminal domestic violence laws solely on physical violence. As a result, state laws often fail to protect victims from future and escalating violence. Focusing on Tennessee law and drawing from the work of Evan Stark as well as the United Kingdom's Serious Crime Act of 2015, this Note proposes adapting the preexisting crime of false …

Building Conflict Resilience: It's Not Just About Problem-Solving, Robert C. Bordone

Journal of Dispute Resolution

Political polarization in the United States and internationally has increased enormously in the past decade, resulting in legislative impasse in some countries, political instability and partisan re-alignment in others, and decreased levels of communication, trust, and cooperation across partisan lines in schools, communities, and across the nation. As partisan polarization has increased, I have observed several perceptible changes in the way law school students engage each other around political differences and conflict in the classroom. From conversations with my colleagues, I am not alone in observing these trends.

Inherently Unneutral Investment Treaty Arbitration: The Formation Of Decisive Arguments In Jurisdictional Determinations, Relja Radovic

Journal of Dispute Resolution

The legitimacy crisis of investment treaty arbitration is much discussed, often challenging the neutrality of that system as a whole. Besides concentrating on the direction in which cases are being decided, or in which the law is being interpreted, the neutrality of investment treaty arbitration as a system can also be discussed from the perspective of its foundations. This article looks at the arbitral use of the two basic ideals of investment treaty arbitration, namely the legalistic and teleological notions, in the formation of decisive arguments, in the particular context of jurisdictional decisions. It examines to what extent the two …

From The Cover: 7,8-Dihydroxyflavone Rescues Lead-Induced Impairment Of Vesicular Release: A Novel Therapeutic Approach For Lead Intoxicated Children, Xiao-Lei Zhang, Jennifer L. Mcglothan, Omid Miry, Kirstie H. Stansfield, Meredith K. Loth, Patric K. Stanton, Tomas R. Guilarte

NYMC Faculty Publications

Childhood lead (Pb2+) intoxication is a public health problem of global proportion. Lead exposure during development produces multiple effects on the central nervous system including impaired synapse formation, altered synaptic plasticity, and learning deficits. In primary hippocampal neurons in culture and hippocampal slices, Pb2+ exposure inhibits vesicular release and reduces the number of fast-releasing sites, an effect associated with Pb2+ inhibition of NMDA receptor-mediated trans-synaptic Brain-Derived Neurotrophic Factor (BDNF) signaling. The objective of this study was to determine if activation of TrkB, the cognate receptor for BDNF, would rescue Pb2+-induced impairments of vesicular release. Rats were chronically exposed to Pb2+ …

Combatting Discrimination Against The Formerly Incarcerated In The Labor Market, Ifeoma Ajunwa, Angela Onwuachi-Willig

Faculty Publications

Both discrimination by private employers and governmental restrictions in the form of statutes that prohibit professional licensing serve to exclude the formerly incarcerated from much of the labor market. This Essay explores and analyzes potential legislative and contractual means for removing these barriers to labor market participation by the formerly incarcerated. First, as a means of addressing discrimination by the state, Part I of this Essay explores the ways in which the adoption of racial impact statements — which mandate that legislators consider statistical analyses of the potential impact their proposed legislation may have on racial and ethnic groups prior …

Water Insecurity And Gendered Risk For Depression In Rural Uganda: A Hotspot Analysis, Christine E. Cooper-Vince, Hawk Arachy, Bernard Kakuhikire, Dagmar Vořechovská, Rumbidzai Mushavi, C. Baguma, Amy Q. Mcdonough, David R. Bangsberg, Alexander C. Tsai

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background:

Water insecurity is linked to depression in low- and middle-income countries (LMICs), though it remains unclear how geospatial clustering of water insecurity in rural regions is associated with risk for depression.

Methods: We conducted a population-based survey of a rural parish in southwestern Uganda (N = 1603) to evaluate the joint geospatial clustering of water insecurity and risk for depression among men and women living in rural Uganda.

Results:

Geospatial clustering of self-reported water insecurity and depressive symptoms was found to be present among both men and women. Depression hotspots were more often observed near water insecurity hotspots among …

From Research-To-Practice: An Adaptation And Dissemination Of The Compass Program For Home Care Workers, Ryan Olson, Jennifer Hess, Kelsey N. Parker, Sharon V. Thompson, Anjali Rameshbabu, Kristy Luther Rhoten, Miguel Marino

OHSU-PSU School of Public Health Faculty Publications and Presentations

The COMmunity of Practice And Safety Support (COMPASS) program was developed to prevent injuries and advance the health and well-being of home care workers. The program integrates elements of peer-led social support groups with scripted team-based programs to help workers learn together, solve problems, set goals, make changes, and enrich their supportive professional network. After a successful pilot study and randomized controlled trial, COMPASS was adapted for the Oregon Home Care Commission’s training system for statewide dissemination. The adapted program included fewer total meetings (7 versus 13), an accelerated meeting schedule (every two weeks versus monthly), and a range of …

Policing Narrative, Tal Kastner

Scholarly Works

Counter narrative, a story that calls attention to and rebuts the presumptions of a dominant narrative framework, functions as an essential tool to reshape the bounds of the law. It has the potential to shape the collective notion of what constitutes legal authority. Black Lives Matter offers a counter narrative that challenges the characterization of the shared public space, among other aspects of contemporary society, as the space of law. Using the concept of necropower--the mobilization and prioritization of the state's power to kill--I analyze the contested physical and conceptual space of law exposed by the counter narrative of Black …

What Does The Fos Say? Using Fos-Based Approaches To Understand The Contribution Of Stress To Substance Use Disorders, Jayme R. Mcreynolds, John P. Christianson, Jordan M. Blacktop, John Mantsch

Biomedical Sciences Faculty Research and Publications

Despite extensive research efforts, drug addiction persists as a largely unmet medical need. Perhaps the biggest challenge for treating addiction is the high rate of recidivism. While many factors can promote relapse in abstinent drug users, the contribution of stress is particularly problematic, as stress is uncontrollable and pervasive in the lives of those struggling with addiction. Thus, understanding the neurocircuitry that underlies the influence of stress on drug seeking is critical for guiding treatment. Preclinical research aimed at defining this neurocircuitry has, in part, relied upon the use of experimental approaches that allow visualization of cellular and circuit activity …

17Β-Estradiol Potentiates The Reinstatement Of Cocaine Seeking In Female Rats: Role Of The Prelimbic Prefrontal Cortex And Cannabinoid Type-1 Receptors, Elizabeth M. Doncheck, Luke A. Urbanik, Margot C. Debaker, Laura M. Barron, Gage T. Liddiard, Jennifer J. Tuscher, Karyn M. Frick, Cecilia J. Hillard, John Mantsch

Biomedical Sciences Faculty Research and Publications

Clinical observations imply that female cocaine addicts experience enhanced relapse vulnerability compared with males, an effect tied to elevated estrogen phases of the ovarian hormone cycle. Although estrogens can enhance drug-seeking behavior, they do not directly induce reinstatement on their own. To model this phenomenon, we tested whether an estrogen could augment drug-seeking behavior in response to an ordinarily subthreshold reinstatement trigger. Following cocaine self-administration and extinction, female rats were ovariectomized to isolate estrogen effects on reinstatement. Although neither peak proestrus levels of the primary estrogen 17β-estradiol (E2; 10 μg/kg, i.p., 1-h pretreatment) nor a subthreshold cocaine dose …

Turbulence, Entrainment And Low-Order Description Of A Transitional Variable-Density Jet, Bianca Viggiano, Tamara S. Dib, N. Ali, L. G. Mastin, Raúl Bayoán Cal, S. A. Solovitz

Mechanical and Materials Engineering Faculty Publications and Presentations

Geophysical flows occur over a large range of scales, with Reynolds numbers and Richardson numbers varying over several orders of magnitude. For this study, jets of different densities were ejected vertically into a large ambient region, considering conditions relevant to some geophysical phenomena. Using particle image velocimetry, the velocity fields were measured for three different gases exhausting into air – specifically helium, air and argon. Measurements focused on both the jet core and the entrained ambient. Experiments considered relatively low Reynolds numbers from approximately 1500 to 10 000 with Richardson numbers near 0.001 in magnitude. These included a variety of …

Investigating Differing Degrees Of Foxo3a Expression In Adult Neural Stem Cells Between Age Groups In Zebrafish, Francis G. Bacik

Cal Poly Humboldt theses and projects

One factor influencing organismal longevity is the activity of transcription factors of the “fork head domain” family, otherwise known as “Forkhead box” (Fox) proteins. Studies of the four isoforms of the “O” subclass of Fox proteins found in human genes have revealed a direct relationship between FoxO3a-dependent gene expression and the conservation of neural stem cell (NSC) in the adult brain, specifically in the subgranular zone of the dentate gyrus in the hippocampus and the subventricular zone of the cortex. This transcription factor has also been shown to regulate apoptosis in nervous tissue during embryonic development in zebrafish. The current …

What's So Great About The Alternative? Understanding Motivations For Participating In Humboldt County Alternative Food Networks, Jessica Smith

Cal Poly Humboldt theses and projects

Participation in alternative food networks such as farmer’s markets, community supported agriculture (CSA), and community gardens has become an increasingly popular way to express opposition to the current industrial food system. Food justice scholars often criticize alternative food networks for operating within a neoliberal economic framework and suggest that structural inequalities within the food system are not able to be addressed by alternative food networks in the same way they are through food justice or food sovereignty. The goal of this research is to discover individual motivation behind participation in local alternative food networks in Humboldt County. I am curious …

The Effects Of Descending Resistance Sets Compared To Constant Resistance Sets On The Volume Completed During A High Intensity Free Weight Back Squat Exercise, Jason E. Meyer

Cal Poly Humboldt theses and projects

Improving anabolic hormone production is an important training adaptation in resistance training; however, no previous research has developed optimized descending resistance sets to increase training volume. The purpose of this research was to compare two different loading protocols of constant resistance sets (CRS) and descending resistance sets (DRS) on the free weight back squat. Eleven resistance trained male participants (mean ± SD, age = 22 ± 3 yr, and back squat 1RM ratio (1RM/body weight) = 1.65 ± 0.2) completed 4 experimental sessions over 2 weeks, during which 4 sets of the back squat were performed with 85% 1RM and …
