In Vitro Evaluation Of The Solubility Of Endosequence Bc Sealer In Acidic Solutions, Inderpal S. Sappal

Theses and Dissertations

Purpose: In recent years, bioceramic sealers (BCS), such as EndoSequence BC Sealer, have gained popularity in endodontic practices. Previous research has found BCS difficult to remove from canals during retreatments when compared with other endodontic sealers. Acidic solutions have been found to inhibit the set of BCS and increase their solubility. The purpose of this study was to evaluate the efficacy of acidic solutions in the removal of BCS as compared with a traditional retreatment solvent.

Methods: Roots of extracted human single rooted teeth (N=15) were prepared into 17 mm sections, then instrumented with ProTaper Gold (PTG) rotary files up …

Test-retest reliability was evaluated using intraclass correlation …

The Impact Of Postmodernism On 21st Century Higher Education, Lia B. Wheatley

Liberal Studies (MA) Final Essays

The American undergraduate higher educational institution was organized and developed well over 100 years ago, and for the most part, it was designed around Eurocentric ideals, experiences, and values—ones that hardly reflect the population and principles of a 21^st century America. The higher education system is undoubtedly a product of modernism; however, as postmodernism has become more widespread through mainstream society, universities must reevaluate their means and their ends in order to meet transitioning standards and expectations especially if academe hopes to remain a pillar of our ever-progressing society.

The three majorly impacted areas of higher education include enrollment …

Nursing, Physical Therapy, And Cytotechnology Graduate And Undergraduate Students' Attitudes Toward Teamwork Before And After Participation In An Interprofessional Education Experience, Shelley C. Mishoe, Muge Akpinar Elci, Rebecca Poston, Kimberly Adams Tufts, Beth Thompson

Community & Environmental Health Faculty Publications

BACKGROUND Educating health professional (HP) students in environments wherein they can learn about, from, and with each other can prepare them for interprofessional collaborative practice (IPCP), which may positively impact patient safety and satisfaction (Brashers et al., 2015; Health Professions Accreditors Collaborative [HPAC], 2019). IPCP is characterized by effective communication, shared values, respect for diverse disciplines and teamwork among health professionals (IOM, 2015). However, professional silos in practice can foster competition rather than collaboration. Knowledge of HP roles and responsibilities is a primary tenet of IPCP (Interprofessional Educational Collaborative [IPEC], 2011).

PURPOSE An interprofessional education (IPE) approach that combined book …

Climate Disruption In Canadian Constitutional Law: References Re Greenhouse Gas Pollution Pricing Act, Jocelyn Stacey

All Faculty Publications

This analysis considers the Supreme Court of Canada’s decision in References re Greenhouse Gas Pollution Pricing Act, 2021 SCC 11, in which a majority of the Court upheld as constitutional national carbon pricing legislation. The decision presents an excellent illustration of the legally disruptive nature of climate change. Illustrating that nothing is static in a climate disrupted world—including constitutional law—this article identifies three shifts the Court makes in relation to climate disruption. First, the decision represents a shift away from climate denialism toward a judicial willingness to confront the environmental, social and legal implications of climate change for Canada. Second, …

Financial Literacy, Experience, And Age Differences In Monetary Sequence Preferences, Jenna M. Wilson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The emerging research on age differences in monetary sequence preferences suggests that older adults make decisions that are normatively correct from the standpoint of economic theory when choosing to receive larger versus smaller amounts of money sooner than later, but make non-optimal decisions about paying money. In an adult life-span sample (N = 594, aged 20-88, M_age = 46.48, SD= 15.16) recruited through MTurk, the present study examined age differences in monetary sequence preferences. Participants received eight hypothetical scenarios that described monetary events, and completed measures of financial literacy and financial experience. Older age was associated with …

Qualitative Study Of Collaboration Between Independent Reading Specialists And Elementary Classroom Teachers, Lindsay Lee Hawbaker

Electronic Theses and Dissertations

Abstract

The failure of educators to meet the needs of elementary students who require separated, differentiated, and intensive reading interventions (Tier 3) has been attributed to the scarcity of administrative resources and a lack of effective collaboration between reading specialists and classroom teachers. Experts opine that common barriers to effective collegial collaboration between institutional reading specialists, who are employed by the school, and classroom teachers include: an unsupportive school culture, the classroom teachers’ fear of losing pedagogical autonomy, the absence of mutual trust and interdependence between the reading specialists and their students’ classroom teachers, and the inability of reading specialists …

Anthology Of An Empath, Meriel Melendrez Mees

Cal Poly Humboldt theses and projects

How can we live here together? How can we, human beings (especially those of us not considered as such, historically, presently, or in the future) and more-than-human beings live here together and care for each other? I set out to learn how a pair of permaculture farmers in Southern Humboldt lived and worked with these questions: I attempted a qualitative and quantitative analysis of twenty years of natural history journals that one of them recorded. I was particularly interested in the aesthetics of land tending, affective relationships with more-than-human beings, and disrupting settler colonialism through epistemic reparations to the Sinkyone …

Why Do People Donate? Motivation Of Major Donors In Higher Education, Karin Hsuan Chao-Bushoven

Cal Poly Humboldt theses and projects

Higher education has relied on private philanthropy since the establishment of the first universities in the U.S. This reliance has increased over the decades as a result of rising costs and decreased government investment. As such, it has become more critical to better understand what factors motivate philanthropists to increase their support of higher education; including direct support for teaching and research and increasing financial support for those students otherwise not able to pursue secondary education. However, much of the existing data focuses only on point-of-philanthropic-act, and neglects to examine motivational factors of long-term donors that have progressively increased their …

Effects Of Prescribed Fire On Drought Resistance And Recovery In Mixed Conifer Forests Of Lassen Volcanic National Park, California, Zachary J. Wenderott

Cal Poly Humboldt theses and projects

Forests throughout much of the western United States are experiencing increasing climatic variability, often resulting in decreased forest productivity and elevated likelihood of tree mortality. Severe drought, such California’s recent 2012-2015 drought, are projected to increase in intensity, frequency, and severity throughout much of this region in coming years. Forest management has long relied on prescribed fire and mechanical thinning to reduce fuel loads and ameliorate potential fire hazards. These treatments may also have the ability to reduce stand density, alleviate competitive pressures, and allow residual trees access to critical resources during periods of extreme stress. Utilizing a long-term National …

Beyond Care And Order In School Climate: A Qualitative Study Of Defender And Outsider Cognitions In Bullying Situations, William S. Richards Iv

Cal Poly Humboldt theses and projects

This study examined the cognitions of students who intervene or do not intervene when they witness bullying incidents along with the ways that these cognitions may relate to these students’ perceptions of school climate at a small, rural high school in Northern California. Because increasing the frequency of bystander intervention has been found in prior studies to decrease bullying, this study illuminates the cognitive processes that support agency to intervene in bullying and distinguish them from cognitive processes that reduce agency to intervene. This study also identifies possible links between the ways students perceive school climate and their agency to …

Exploring Renewable Energy Futures In Humboldt County Consistent With The Goals Of California’S Renewable Portfolio Standard, Amin M. Younes

Cal Poly Humboldt theses and projects

Humboldt County has abundant wind, solar, and biomass resources, but has made limited progress towards the state’s 2045 requirement of 100% clean electricity. A recently rejected onshore wind project showed that technically and economically viable projects can fall to social and political challenges, emphasizing the need for social considerations in renewable transitions. I therefore integrated community members’ preferences into modeling of RPS-consistent renewable energy scenarios in Humboldt County. My model suggests that offshore wind, utility-scale solar, distributed solar, and biomass power are technically and economically viable sources of significant local generation at varying costs.

In interviews with energy-engaged residents, I …

May All Teachers Be Happy: A Mindfulness Manual For School Staff, Laura Ella Ashley

Cal Poly Humboldt theses and projects

There are many teachers who leave the profession early due to burnout; furthermore, there are many requirements for teachers to support the social emotional wellness of their students. With training provided to teachers as to how to help students as the norm, and no support for helping the teachers who are burnt out, this project aims to bridge this gap. After facilitating and surveying participants in a mindfulness staff group, the results of this study clearly show that teacher well-being can be supported, and enhanced, with a simple mindfulness support group provided on site to school staff.

The Role Of Hardiness And Autonomy Support On College Student Engagement, Kevin Douglas Cherry

Cal Poly Humboldt theses and projects

The gap between college student enrollment and graduation rates remains a problem for college students and administrators. Literature on persistence in college suggests that factors such as hardiness and autonomy support may contribute to student perseverance through degree attainment. The current study focused on these constructs using a framework based on self-determination theory (SDT; Ryan & Deci, 1985). Factors related to student persistence, namely hardiness and autonomy support, were expected to positively predict college student engagement. Furthermore, hardiness was expected to moderate the relationship between autonomy support and college student engagement. College students from a university and a community college …

Write Yourself Awake: The Double Pursuit Of Mindfulness Meditation And Writing, Alysia M. Hegg

Cal Poly Humboldt theses and projects

Contemplative pedagogy involves teaching methods designed to cultivate deepened awareness, concentration, and insight. Contemplative practices work to undo the Cartesian mind–body dualism that says that mental phenomena are non-physical, or that the mind and body are distinct and separable. This project focuses on an understanding that our internal world includes communication with one’s self, acts of imagination and visualization, and recall and memory. These internal experiences foster many things, such as compassion and kindness, as well as resilience and sustainability through connection.

“McMindfulness” is a term that refers to when mindfulness is used for self-serving and ego-enhancing purposes. Symptoms of …

Can A Remote Sensing Approach With Hyperspectral Data Provide Early Detection And Mapping Of Spatial Patterns Of Black Bear Bark Stripping In Coast Redwoods?, Shayne R. Magstadt

Cal Poly Humboldt theses and projects

The prevalence of black bear (Ursus americanus) bark stripping in commercial redwood (Sequoia sempervirens) timer stands has been increasing in recent years. This stripping is a threat to commercial timber production because of the deleterious effects on redwood tree fitness. This study sought to unveil a remote sensing method to detect these damaged trees early and map their spatial patterns. By developing a timely monitoring method, forest timber companies can manipulate their timber harvesting routines to adapt to the consequences of the problem. We explored the utility of high spatial resolution UAV-collected hyperspectral imagery as a …

A Comparison Of The Removal Of Estrogen Between Different Wastewater Treatment Processes, Danielle J. Jones

Cal Poly Humboldt theses and projects

Pharmaceuticals are found in water systems and are classified as contaminants due to their adverse effects on numerous types of aquatic organisms. Estradiol, a natural occurring estrogen and ethinylestradiol, a common synthetic estrogen found in birth control, are a class of pharmaceuticals called endocrine-disruptive contaminants (EDC). These contaminants have been shown to cause developmental delays in fish as well as feminizing male fish in concentrations as low as 1 ng/L for both estradiol and ethinylestradiol, and bioaccumulating in mollusks and oysters. There are many natural and human-assisted methods for removing pharmaceuticals in water, and they are dependent on both the …

Wingate Muscular Power Test Reference Values For Active Healthy Adults Ages 19-29: Normative Data And Differences Between Sex, Levi Basist

Cal Poly Humboldt theses and projects

The Wingate Muscular Power Test (WMPT) has existed for several decades and to this day is considered the gold standard for evaluating an individual’s muscular power. However, the utility of this test is predicated on having accurate and relevant normative data with which to compare individual results. At present, the existing literature on this subject is either several decades old and/or inclusive of only specific subject groups (i.e. men only or sport-specific athletes). This study presents WMPT normative values for active healthy adults ages 19-29, separated by sex. The sample consisted of 330 active healthy volunteers (186 men and 144 …

Laboratory To Landscape: Mycorestoration, Riley Sanae Allen

Cal Poly Humboldt theses and projects

Mycorestoration is the use of saprophytic fungi to remediate pollutants from land and water. To address contaminant presence in non-point source pollution primarily from agricultural runoff, we worked towards identifying the community-scale implementation process of mycofiltration, a type of mycorestoration that filters contaminants from water, in Arcata, California. This place-based study used Participatory Action Research (PAR) to collaboratively conduct Transdisciplinary Research (TR) to collect baseline qualitative and quantitative data that did not exist for Arcata’s context. These data have been compiled into a written implementation plan which is intended to exist as a living document that is referenced and transformed …

Use Of Redwood Basal Hollows By Bats: A Focus On The Townsend's Big-Eared Bat On The North Coast Of California, Amon Jotesh Armstrong

Cal Poly Humboldt theses and projects

Loss of roosting resources, either through disturbance or removal, negatively affects bats. For sensitive species, such as the Townsend’s big-eared bat (Corynorhinus townsendii), determining roost requirements is a critical component in conserving their habitat. Such cavity roosting bats on the North Coast of California may use hollows in large redwood trees. In this study, I examined the factors determining the use of basal tree hollows by different bat species at eight redwood forest sites in Del Norte, Humboldt, and Mendocino Counties, California. Bat guano was collected from 179 basal hollow roosts from 2017 to 2018, and guano mass …

A Techno-Economic Comparison Of Battery Electric And Hydrogen Fuel-Cell Transit Bus Fleet Options For Humboldt County, California, Aditya S. Kushwah Mr.

Cal Poly Humboldt theses and projects

This study analyzes the techno-economic feasibility of converting the conventional transit bus fleet of the Humboldt Transit Authority (HTA) into a battery-electric or a hydrogen-fueled bus fleet. The study identifies which of these technologies represents the more economically viable investment for HTA by analyzing the costs and benefits associated with each pathway. Both pathways involve zero-emission or low-emission technologies.

The study outcomes suggest that the conversion of the HTA’s current conventional fleet to an electric fleet is more feasible than conversion to a hydrogen fuel cell bus fleet. The total discounted cost (3% rate) of converting the 21-bus conventional fleet …

On The Acceptance Of Urban Beavers In Martinez, California, Zane A. Eddy

Cal Poly Humboldt theses and projects

As ecosystem engineers, beavers construct complex riparian and wetland habitats that benefit many other species, including endangered salmonids. Through their landscape alterations, beavers also promote increased groundwater recharge and provide refugia during wildfires and high flow events by impounding water and allowing it to spread across the landscape. Prior to the North American colonial fur trapping campaigns, there were between 60 and 400 million beavers in North America. By the beginning of the 20th century, beavers were extirpated from many parts of the continent, however through human efforts, their population has since rebounded to between 10 and 15 million. The …

A Survey On The Status Of Acceptance And Commitment Training In Rural Northern California, Jacqueline A. Morris

Cal Poly Humboldt theses and projects

The interest in acceptance and commitment training (ACT) from within the applied behavior analysis (ABA) community has increased as evidenced by recently published literature addressing the need to examine the acceptability and utilization of ACT within ABA. However, there is limited literature on the perspectives of those working in the field of ABA on the use of ACT. In the present study a survey was conducted of ABA practitioners working in rural northern California to evaluate their level of interest in ACT, their perceptions of ACT being within the scope of practice of ABA, and any perceived challenges in developing …
