A Qualitative And Quantitative Study Of Required Internships: The Students’ Perspective, Elizabeth Ann James

Theses and Dissertations--Educational Policy Studies and Evaluation

Internships are increasingly popular in higher education (Coco, 2000; Divine et al., 2007). One reason for the increase is the benefits, both perceived and documented, associated with them (Divine et al., 2007). In addition to offering internships as electives, some programs have even begun requiring them of all students (Klein & Weiss, 2011). The policy change from elective to required internships has been evaluated very little, if at all, even though mandatory internships result in a substantial increase in cost and commitment for the departments that implement them (Divine et al., 2007).

This study analyzed survey and interview data from …

Examination Of Resistance Settings Based On Body Weight For The 3-Minute All-Out Critical Power Test, Marlene J. Schulte, Jody L. Clasey, Bradley S. Fleenor, Haley C. Bergstrom

Kinesiology and Health Promotion Faculty Publications

There are conflicting suggestions regarding the most valid resistance (3-5% of body weight) to use for the critical power (CP) 3-min all-out (CP_3min) test to estimate CP and anaerobic work capacity (AWC). The purpose of this study was to determine if the CP and AWC estimates from the CP_3min test were affected by the percentage of body weight used to set the resistance on a Monark cycle ergometer. Ten recreationally trained participants (mean ± SD: Age: 22.2 ± 2.2 yrs.) completed the CP_3min test at resistances of 4.5% (CP_4.5%) and 3% (CP_3%) …

“From School Of Crisis To Distinguished”: How One School Continues To Defeat The Odds, Ben Crawford

Theses and Dissertations--Science, Technology, Engineering, and Mathematics (STEM) Education

Despite conditions that would work against a small rural school in an impoverish area of rural Kentucky, Fairway Elementary School has managed to excel in its accountability measures. This study used a mixed-methods approach with data collected through interviews and MAP student growth scores in reading and mathematics. Five themes emerged from the qualitative data regarding school success: (1) a well-organized intervention system, (2) a focus on and overall enjoyment of the discipline of mathematics, (3) involvement of parents in school functions, (4) transparency of needs and organization of resources, and (5) an overall school culture that is competitive, impactful, …

Building Teacher Efficacy: Challenges Of Creating Communities Of Practice Among New Teachers And Veteran Teachers In A Toxic Work Environment, J Lail

Theses and Dissertations--Educational Leadership Studies

Recently, changes in graduation requirements in some states have made it more important than ever for students to be literate in all content areas. State assessments not only measure student academic ability, but they are a necessary component of graduation from high school. After completing required courses, students are expected to take assessments covering the content of those courses. In order to safely meet the graduation requirement, students must score at least 3 points per assessment on a 5-point scale. This has proven difficult for over 50% of students expecting to graduate.

Students at Midwestern-American High School (MAHS) have been …

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. …

Paracest Agents Encapsulated In Reverse Nano-Assembled Capsules (Racs): How Slow Molecular Tumbling Can Quench Cest Contrast, Annah Farashishiko, Jacqueline R. Slack, Mauro Botta, Mark Woods

Chemistry Faculty Publications and Presentations

Although paraCEST is a method with immense scope for generating image contrast in MRI, it suffers from the serious drawback of high detection limits. For a typical discrete paraCEST agent the detection limit is roughly an order of magnitude higher than that of a clinically used relaxation agent. One solution to this problem may be the incorporation of a large payload of paraCEST agents into a single macromolecular agent. Here we report a new synthetic method for accomplishing this goal: incorporating a large payload of the paraCEST agent DyDOTAM3+ into a Reverse Assembled nano-Capsule. An aggregate can be generated between …

Free-Base Nicotine Determination In Electronic Cigarette Liquids By 1H Nmr Spectroscopy, Anna K. Duell, James F. Pankow, David H. Peyton

Chemistry Faculty Publications and Presentations

E-liquids usually contain significant nicotine, which will exist primarily in two forms, monoprotonated and free-base, the proportions of which are alterable through the effective pH of the medium. The fraction of nicotine in the free-base form is α_fb, with 0 ≤ α_fb ≤ 1. When dosed via aerosol, the two nicotine forms have different mechanisms and kinetics of delivery, as well as differing implications for harshness of the inhaled aerosol, so α_fb is relevant regarding abuse liability. Previous attempts to determine α_fb in electronic cigarette liquids and vapor have been flawed. We employed the exchange-averaged …

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 …

Does Combined Therapy Of Curcumin And Epigallocatechin Gallate Have A Synergistic Neuroprotective Effect Aainst Spinal Cord Injury?, Jiri Ruzicka, Lucia M. Urdzikova, Anubhav Amin, Sarka Kubinova, Meic Schmidt, Meena Jhanwar-Uniyal, Pavla Jendelova

NYMC Faculty Publications

Systematic inflammatory response after spinal cord injury (SCI) is one of the factors leading to lesion development and a profound degree of functional loss. Anti-inflammatory compounds, such as curcumin and epigallocatechin gallate (EGCG) are known for their neuroprotective effects. In this study, we investigated the effect of combined therapy of curcumin and EGCG in a rat model of acute SCI induced by balloon compression. Immediately after SCI, rats received curcumin, EGCG, curcumin + EGCG or saline [daily intraperitoneal doses (curcumin, 6 mg/kg; EGCG 17 mg/kg)] and weekly intramuscular doses (curcumin, 60 mg/kg; EGCG 17 mg/kg)] for 28 days. Rats were …

Do Investors Still Gravitate To Preferred Habitats On The Us Treasury Yield Curve?, Kenneth S. Dreifus, Angelo Decandia, Elliott Goldberg, Mohammed Chowdhury

New York School for Career and Applied Studies (NYSCAS) Publications and Research

The purpose of this study is to test the preferred habitat theory non-econometrically using interviews with the help of a questionnaire for self-guidance on a group of focused investors. Frequencies and simple percentages were used to analyze data. Though many generations of post-World War II economics and finance students were taught that the nature of the liabilities on the balance sheet and the desire to avoid mismatches against assets caused particular classes of investors to gravitate to a preferred habitat on the yield curve, our study based on the responses to questionnaires by a group of U.S. based bond traders …

Connecting Chemistry To Community With Deliberative Democracy, Regis Komperda, Jack Barbera, Erin Shortlidge, Gwen Shusterman, Stem Education And Equity Institute, Portland State University

Biology Faculty Publications and Presentations

Science education communities have called for rethinking curricula to improve student understanding of the nature of science and the role of science in addressing controversial modern issues such as climate change, energy policy, and pollution levels. One approach to meeting this call is integrating these topics into class activities that require students to use discussion and scientific approaches to solve problems and deliberate potential policy solutions. Deliberative democracy (DD) is one such active learning approach in which students work in peer groups to reach a consensus on a scientific topic relevant to both real-world issues and course content. During DD …

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 …

Post-Fire Regeneration And Fuel Succession Patterns In Hesperocyparis Bakeri Forests, Bret Anthony Mcnamara

Cal Poly Humboldt theses and projects

Climate change is predicted to cause widespread redistribution of suitable tree habitats, as well as increase the size and frequency of wildfires in the western United States during the forthcoming century. Rare serotinous conifers may have heightened sensitivity to the impacts of both fire regime and climate shifts for multiple reasons. First, the rapid spatial rearrangement of suitable habitat will disproportionately affect trees with constrained seed dispersal capabilities, and limited dispersal is a trait associated with some genera of serotinous trees. Second, a number of serotinous conifers depend on fire disturbances for regeneration, though with the expected increase in annual …

The Effects Of Ocean Acidification And Reduced Oxygen On The Behavior And Physiology Of Juvenile Rockfish, Corianna H. Flannery

Cal Poly Humboldt theses and projects

As climate change progresses, the frequency and duration of upwelling events that bring low pH, low dissolved oxygen (DO) water to nearshore habitats are expected to increase. In addition, long-term global changes in ocean pH and DO are expected to occur within the next few decades to centuries. Locally, there have been documented reductions in near-shore pH along with the expansion of oxygen minimum zones within the California Current System. However, very few studies have investigated the potential interactive effect of these stressors on temperate reef fish. For this thesis, two sets of laboratory experiments were conducted to determine the …

Religion, Language, Gender, And Culture: Challenges Experienced By Saudi International Students In Humboldt County, Dafer Sahab Alqarni

Cal Poly Humboldt theses and projects

The effects of culture shock on individuals living abroad are well known. Less well known, however, are the specific experiences, needs, and challenges of Saudi Arabian students studying internationally, especially in Western nations. In this study, I used qualitative research to explore the needs and difficulties of Saudi international students in Humboldt County and at Humboldt State University (HSU). Using semi-structured interviews with eight participants, diversified by gender and marital status, I provide a holistic view of HSU Saudi international students’ experiences and challenges which could help to understand Saudi students’ experiences abroad generally, and in Humboldt County specifically. I …

Utility-Scale Solar Photovoltaic Hosting Potential Of Historic Mill Sites In Humboldt County, California, Michael Avcollie

Cal Poly Humboldt theses and projects

The adoption of Redwood Coast Energy Authority’s (RCEA’s) Community Choice Energy program in May of 2017 across Humboldt County has sparked interest in locally produced energy from solar photovoltaics (PV). RCEA has a goal of bringing 5 Megawatts (MW) of local, utility-scale, solar PV under contract by 2018 and 15 MW by 2023. Humboldt County’s former mill sites offer features that make them suitable for hosting PV development. This study performed an inventory and analysis of these sites to answer two questions: Can Humboldt County’s former mill sites provide the hosting capacity for15 MW of local, utility-scale solar PV? Which …

Effects Of Manual And Mechanical Ammophila Arenaria Removal Techniques On Coastal Dune Plant Communities And Dune Morphology, Monique R. Silva Crossman

Cal Poly Humboldt theses and projects

The removal of invasive species as part of the restoration process can allow natives organisms to rebound. An ecosystem that incurs damages from invasive species is coastal sand dunes, which are dynamic systems. Some coastal sand dunes on the west coast of the United States have been invaded by Ammophila arenaria. The invasive grass, A. arenaria, is thought to alter and stabilize foredune morphology and reduce populations of native species. The objectives of my research are to examine the effects that manual and mechanical A. arenaria removal techniques have on coastal sand dune morphology and vegetative cover over time. …

Assessing Spatio-Temporal Patterns Of Forest Decline Across A Diverse Landscape In The Klamath Mountains Using A 28-Year Landsat Time-Series Analysis, Drew S. Bost

Cal Poly Humboldt theses and projects

Rates of tree mortality in California and the Pacific Northwest have greatly increased in recent years, driven largely by pest and pathogen outbreaks as well as the effects of hotter, warmer droughts. While there have been a multitude of regional-scale assessments of mortality and forest decline, landscape-level studies are necessary to better identify forests that are most vulnerable to decline and to anticipate future changes. This need is particularly notable in the remote and little-studied mountains of northwest California, which are renowned for their diverse, heterogeneous vegetation types. A recent observation of elevated levels of Shasta red fir (Abies …

Music And The Brain, Maddie Nierman

The Science Journal of the Lander College of Arts and Sciences

Music is an important part of cultures worldwide. It has been used throughout the ages as a method of conveying emotions to the listener. However, there is some confusion about exactly which areas of the brain are affected by music. This study shows the general areas of the brain stimulated by music, explaining how these sections influence emotion and learning capability. In addition, this paper demonstrates that music therapy may be helpful in relieving stress or some neurological disorders, based on the areas activated by music. Training in music has cognitive and motor coordination benefits, as well, because this training …

Resilience And Native Girls: A Critique, Addie C. Rolnick

Scholarly Works

The term resilience is often used with reference to Indigenous women and Indigenous youth. Native girls are included in each of these categories but are rarely the main focus of a campaign. Their triple vulnerability (gender, indigeneity, and age), however, means that the focus on resilience is often greatest when applied to them. This Article centers them. It traces the development of resilience in the (non-Native) ecological and psychological literature. Although resilience is used across many different disciplines, it is especially prominent in ecological literature about resilient institutions, such as communities and cities, and in psychological literature about resilient individuals. …
